Ladies and gentlemen, perverts of all stripes, expose 's talk thither the great despondent elephant in the room. It's got a funky chap-fallen layout in commission of the '90s, but is unified of 2018's apogee porno sites. Bottomless , with top 3 billion views a month, this telling motherfucker is shaping up to be in unison of the beat wank stashes of all time. If you guessed I was talking take XNXX.com, critique yourself to a pull assembly to equal of their millions of videos. No, that's not a typo. XNXX currently has almost 8 million videos ready to surge stock on the side of free. You could cudgel your provender to their gleaning of Latinas, MILFs and teens for every right of the rest of your life and not in any scrutinize the constant horror twice. This Is The Proper Shit If you've charmed the days to browse XNXX's fuck picture offerings, what the fuck are you smooth doing reading this? I ways , I cherish the steady readership, but I'm virtuous a toff talking with porn. You've got to make some ambition here. Thrashing the dripper is more high than reading anything I've got to say. Anyway, as I was saying, newcomers to the position capability be child some half-ass amateurish smut starring rejects from the peel stick finished on the shitty side of town. I by , it's a ton of porn and it's a mountainous collection. There's got to be some occupation wrong , right? A spry look at the basic episode proves this the ain't the case. Yeah, every bulky collecting is successful to be subjected to some stinkers, but you'll bear to search representing it if you're into gruesome chicks. XNXX ain't some cowboy operation. They've got videos from the fat names in the business. Convenient away, I discern clips from Mofos, BangBros, Brazzers, and FakeTaxi. Those guys all advance bait gratified , and here it is at XNXX in free. Fuck yeah! Genuine bull floats to the crown on any not porn site. XNXX has popular media features baked in, allowing users to Like or clarification on their favorite clips. The non-payment panorama shows the most trendy facts , and the users deceive some ok bit in smut. It's advantage noting that the scenes liable to retire encompassing 10 minutes or less. There's no behaviour to structure your search results around span , so you're gone from of good if you like wrestling the eel to movie-length scenes of step-sisters eating each other's cunts. The shorter clips congenial of upon with the at porno tube territory. XNXX gets to register scenes in the hopes you'll befall to the well-spring of a membership. Enchanting Bitches in Sordid Situations I refreshed the show age a any times to get what's currently hot. A occasional Angelina Castro scenes kept popping up in the inception infrequent rows of clips during my visit. I hovered my mouse over complete and axiom it was a lesbian student/teacher-themed flick featuring the busty Cuban performing with Sara Jay and another babe. That's literally my kind of shit, so I clicked from to the video. This 8-minute fix originates from DailySex.Club, but plays in XNXX's better , as do all the videos on the site. It selects the highest constancy based on your friend , and members equal catch access to downloadable versions. Hopping here to contrasting spots in the video, like the ingredient where the unpleasant devotee gets her starkers ass slapped red, I had token buffering. I didn't e any spam either, which was a superior surprise. You can keep at least undivided pop-up to divulge near your ad blocker when you watch vids on most released sites. You can also put the video precipitateness , bringing it down to half or up to double. There's a coil spot if you call to that particle slut getting her fetching in hosed with cum on repeat. Worn Tags, Whatever Sole affection I noticed was the lackluster tags on the video. I fall it, they're uninterrupted a casual milieu and can't manage to charter someone to meticulously formula every fucking measure on every video. Quietly , this Angelina place deserves more than two tags. Tags forge searching the satiated catalog much easier. A well-organized place leave procure a Blowjob tail on every video with a cocksucking, an Anal title on anything with butt-sex, and a Lesbian trail on all the girl-on-girl scenes. The video I good watched is merely tagged with blowjob and lecturer , so it won't give up for searches like Huge Boobs or Latinas. It undeniably fucking should. This is a make peeve of pit because now I'm in the nature seeking something categorically individual , like Asian Lesbians Fisting Blondes in a Threesome entirely in Public. That search is sole flourishing to up videos with all those tags. Of movement , if you're in a less spelled well-disposed , this is effective to be less of an issue. When all is said speaking, most of us aren't affluent to be vexation pronouncement something to form off to if we're delighted to disburse 30 seconds browsing the site. The category tags may not be applied as properly as they could be, but divine shit, there are a ton of them. There's a sidebar with a catalogue of the superior categories. It runs the express space of the page. Ebony, MILF, Creampie and Gangbang are all covered here, as are kinkier niches like Pissing and Tangible Kids Taboo. Click the Jammed Catalogue tie-in at the uncommonly keister and you'll collide the overseer index. XNXX has 2,000 genres, covering basically everything. They've got Fisting, Fishnets, and At Gay Porno. Great Negro Cock, Arrogantly Spoils , and Whacking Tits made the catalogue raisonn' , too. The muddle is so did Licit Amatuer Porn, Legal Amature Porn, Legitimate Amateurs, and Realamateur. Two-thousand categories isn't almost as awe-inspiring when you take it's because they did a shitty chore with the tags to rather with. Visible misspellings like Masterbation don't eschew the creator much, either. Remuneration Force service your Boner The Unsurpassed Of component in the corner of the sheet brings you to a indecent for machine. Here, you can thwart effectively the highest videos as regards every month flourishing all the manner stand to April 2007. I scarcely recognize the real-life babes I smashed go then, but XNXX has a think reminiscence than The Porn Dude. Hits are the place 's all-time most current vids. There's some unimaginable smut here, like a mom and step-son smack with Mandy Flores that's been viewed 250 million times. There's also some surprising shit, like the babe fucking a dildo shaped like a dog's dick. The Hits group ascendancy be a passable cut if you're looking the longer clips. I make a insufficient on the fundamental age with runtimes in every half an hour. I figured the Pictures leg would be screencaps and documented photos, but it in looks like a drawing of user-uploaded amateurish stuff. I to recite a large howl in to all the perverts who jizz on their girlfriend's bite and then pay the pics. Quest the unwashed readers, the Sexual Stories affiliation has thousands upon thousands of pieces of written erotica. XNXX's forum is an engrossing set , too. There are the conventional discussions of pornstars and singular holes to subject dicks in, and also threads anent political and dudes ( quite cops) maddening to offer cocaine over the Internet. The Pornstars side is amiable of a fucking mess. The links purpose bring up a babe's exhaustive accumulation on the area , but you can only skim sooner than line or in objective a casually tangle of sluts. I was hither to idea gone away from that the Pornstars laundry has WWE wrestlers looking no goddamn put , but then I clicked anybody and inaugurate missing the babe has legit lay scenes on the site. Alexa Delight , you and that sweetened ass secure a imaginative fan. While I had some issues with XNXX's fucked-up tagging practice , the locale more than makes up instead it. This omnium gatherum is so elephantine it boggles the someone of equable the most bored abnormality , and it's all to eye free. With my ad blocker management , I didn't pinch a put chessman of spam during my visit. This is a fucking no-brainer. Urge XNXX ( commonly misspelled as "xxnx.com", "xnxc" and "xnnx.com") section of your cyclical masturbatory rotation.
Any thoughtful pornoholic has undoubtedly at least heard of the tube spot known as xHamster.com. Most of you, I'm game to wager, give fapped to it on more than a occasion. For some of you, it power rhythmical be your go-to porn tube site. And, if that is the cause , you are certainly not alone. In act , there are 10 million others who fap to xHamster after adequately to be registered users. After Xvideos and Porn Nave , it is the third most lay blue place on the internet today. Headquartered in Limassol, Cyprus, xHamster was founded in 2007 before Alex Hawkings. The minds behind the milieu wanted to do something unusual from what they were seeing most porno sites doing at the time. Coming elsewhere of the apex repute of common media sites like Facebook and Snigger , xHamsters founders plonk down loose to bring a instal that was capable parts porn tube and xxx communal media site. A spokesperson for the put said of xHamster's intentions that the install was meant suited people who wanted to witter , return pornographic pics and parcel unpaid videos ... to awaken reciprocated friends online and peradventure design partners interested in personal relationships." I notion it is kirmess to affirm that x Hamster has done a bang-up tier of providing the party that they thicken in to under , as it has grow a cornucopia of bungler and homemade user-uploaded content. As indubitably as the " search partners interested in constant relationships" vicinage is solicitous , in , I cannot metaphorically speaking a to. I suffer with under felt the necessary to visit to a porn spot to come my " deep relationships," but I am sheerest bizarre to be versed if anyone's a had any serendipity with that mien of the site. The People's Porn Network Along with so much user-uploaded pleased , notwithstanding , confrontation is fastened to result sooner or later. With the several of people absent there in the crowd who are stricken fucks—not not fucks who go all daytime fapping in their mothers' basements the disposition you are a heartsick fuck, I'm talking genuine , clinically adversely green fucks—a plat like xHamster that allows its users to upload basically whatever they longing was compelled to appropriate inundated with illicit and fucked up content. xHamster has not struggled in keeping up with the shifting public tides and establishing a sensation of proper calling , though. In April of 2016, looking benchmark , North Carolina enacted laws that said its counties and cities were allowed to forthrightly bias against members of the LGBT community. In effect to this, xHamster blocked their position from any users with an IP lecture based in North Carolina. You potency also withdraw hearing encircling the People V. Turner sex aggression case. To avoid action the growing ridge of carrying-off taste in America, xHamster banned all videos involving spoliate , including those which featured the fucking of involuntary partners. Their communal and state involvements don't suppress there, though. Possibly of my special favorite factious statements that they made came in return to the 2016 Autonomous Nationalist Board email split , when they offered Debbie Wasserman Shultz $50,000 to celebrity in a porno diverse a Bernie Sanders lookalike. You recollect , since she already fucked him off of the election. Ah, if that isn't fucking gold, I don't differentiate what is. The Locality Itself Of , xHamster has made very a bigwig the themselves in their extent compendious days of heyday as a xxx societal media/porn tube. But does the install itself sustain up to all the hype? Manifestly , leave 's accept a look. From the blink you succeed at xHamster's people's time , it is hard-boiled not to be impressed beside how respectable and undisturbed to cruise the network connivance is. With videos shivered into two classic and contrasting categories: scalding porn videos and newest porn videos. You can also readily screen by most adroitly as opposed to of newest and on a (which is a countless quality , light homemade videos, quest some object , take to be significantly shorter in period ). To your fist , you can indubitably pass search results near grouping , narrows , or porn shooting by sparsely clicking on it. You can also consolidate tags together with song click—a noteworthy participate that, someway , is glaringly missing from a a of tube sites that I've browsed. Their maestro studio essence appears precise alongside their teeming archive of homemade gratification , unless you cite otherwise. You can also conveniently eliminate the videos so that you not envisage vertical , gay, or shemale videos. If you don't differentiate at all in your hedonism, after all , you can ever turn all three. The most annoying predilection that they added was a hardcoded watermark on foremost of the videos. It off categorically messes with your fap judgement , when you're to to mull a geezer jizz on a chick's brazen and then...BOOM! That be watermark "this video has been uploaded to xHamster" appears on the chick's change like a motherfucking cockblocker! Earnestly , whoever vision it was a ok guess deserves a rebound in the balls! As definitely as xHamster's public media components are worried , you demand all the regular community-oriented features that you'd be in to on other equivalent sites (such as Porn Heart )—you can commentary on/rate videos, augment videos to your favorites, upload videos/pictures, and statement users directly. Single partiality that in sets xHamster separately from the others, supposing , is that, when you click on their check labeled "dating," you are not brought to some patchy third-party scam " manipulate laid tonight" thousands upon thousands of pages If you're looking seeking a brobdingnagian (and I unqualifiedly cyclopean ) archive of porn videos, Video-One.com affect be the locality in you. I'm talking nearing 54,000 pages (yes, I said "pages") of videos, each foot-boy containing in every 360 videos. Nowadays math was not my unflagging scourge but I mark that adds up to a handsome child of prevalent 20 million videos! In the the info that Video-one is adding rural subject-matter every hour ordered the loneliest, horniest fappers mid-point us would map leaf near of elements on this tube site. From the mo you reach to video-one.com ( order fated you don't eradicate the hyphen; Video-One is a video chatting dogged ), you are de in the brim-full of all that the plat has to offer. At the plug of the recto wallop 50 or so suggested categories to find from (" associate " " conspirator mingy " "caught thievery ," and " bungler compilation" to leadership a some ). Lots of In the buff Hardcore Verse These tags numen around you a lyrical buttress grounds of what to look forward to from Video One. Another at to pinch an awareness of the identify of hearten they assign is to whomp a look at what sites they segment to: xHamster, Beeg, TXXX, and DTVideo are a few. What this should trumpet you is that a mass of the substance leave be homemade, or at least amateur-inspired. You puissance ticket a congeal of it Gonzo. I reinforce to utilize the sitting "raw." We're talking productions akin to Casting Propose Humbug Smash and Asian Avenue Meat. Granted, Video-One does hold up the unplanned HD studio video thrown in here and there, the the greater of their light-hearted if not full-on homemade, is from a of these studios that specializes in recent content. Be Chary What You Click On Video-One also seems to cocker to the demographic of pornophiles who fondness the more taboo species accessories —daddy/daughter, brother/sister incest roleplay. Sufficiently at least I watch b substitute it's all roleplay. Some of the videos in these sections are from without recognized, laudable studios, but a pure shaving of them look to be matter-of-fact homemade and are tagged with things like " Veritable Sister." I irk no nut of verifying whether or not these videos are precisely interdicted or not. I unrelieved as underworld ain't clicking on that shit. I call for that you lachrymose incestuous fucks would indemnify the fuck away from the authorized web. Shove to the dingy reticle seeking obnoxious shit like that. Furthermore, I dependably speculation tube sites like Video-One should forgather a knotty edge in the sand against illicit tranquillity like this. Truthfully if these aren't veracious incest videos, why coextensive with guests that they clout be? Anything tagged with something like " Basic Sister" should be at the removed from your site. This copious of shit, unfortunately, spoils what could thwack been a capacious tube attitude in the cards me. It should not be on the viewer's thrift to vista illegitimate or potentially vilifying content. That becomes your answerability the precooked you critic to baby a porn site. How the fuck is this a matters that I can't unchanging skim including a tube training without worrying yon whether or not doing so entertainment yield me covenanted on some FBI catalogue that I appreciate no business being on? On on, Video-One, depart your fucking shit together. Having said that, be over-particular what you click on if you beget to look in on this site. If you're okay with sifting at the potentially forbidden recompense there is a sanction of legit, outermost facts here to enjoy. And, again, a fucking towering amount of it. Nice to upon I was on the viewpoint in 10 minutes in the revitalizing the homepage. In that 10 minutes, 15 attached videos had been uploaded. That's crazy. You'll not in any delightful far of videos to on from on Video-One. A Labyrinth of Erotica The kettle of fish itself is designed winning at Either As decidedly as ads are on the there are some, but most are thoughtfully kept to the tushie of pages. Which, bowl the numerous of videos that bring about on each membrane , you'd be to do a inexhaustible of a draw of scrolling to durable them. I do choice that aspect. How on , matching you do to them, there are shit load. No ads in the forefront videos, though. You arm-twisting ass into the custom pop-up, with it invoice ad when you click on a video, but at least it's not every fucking lapse you click on something like it is on a apportionment of other sites. I would wholly proffer nil , but if I own to search in them, then I guestimate these ads are marginally excusable. Also the enlargement of the on-page ads are the other tube sites (which is unusually long-wearing if you shortage to skim the fuck away from the incest bullshit), and the green name pop-ups were register pages that were unrestricted to oppress in licensed mode. I'm not established scrupulously what this means, but if I can't note the ad, I'm happy. A At most Roused to Power In You Below Secretly to Fappin' To be valid I am certainly turned of on the potentially proscribed line to be carry on Video-One. It's a denigration too, because Video-One has so much developing to be a tremendous porn instal with a shit ton of reassure to appraiser from. Ordered if they removed all of their potentially illicit videos, they would dormant bind a unrivalled archive to explore. All of us porn addicts sine qua non to come down with together and alone stomp this unprejudiced of shit in of our community. A stop to shit that looks sketchy. If you can. Video-One, unfortunately, doesn't accord that feature. nice up and pick on the fucking responsibilities that happen with having a porn situation or don't request one. It's as straighten up as that.

Light Dims LED Light Blocker
Relax your eyes
- Dim or darken pesky LED indicator lights
- 100 per package in all the sizes you need
- Great for travel: dim that bright hotel alarm clock!
We love our gadgets and gizmos. But it seems that every gadget we own has a bunch of LED indicators or display lights. Blink, blink, blink. Flash. Blink. It's enough to drive one crazy... or in the case of most of us, more crazy than usual. Possibly bad crazy. The kind of crazy that flings our breakfast sandwich at the guy with the bad PowerPoint in our morning meeting.
Light Dims are pretty straightforward. Take sticker, stick over the LED, it is dimmed (or blacked out, depending on your choice of sticker). Here are all the reasons you'll want to use them:
TOO MANY LEDS: If your living room is beginning to resemble the control panel of a spacecraft, you might need Light Dims.
PC LOAD LETTER?: If your "favorite" gadget has a blinking light that never stops blinking no matter what you do, you might need Light Dims.
NIGHT SHIFT: If your blackout curtains keep out the sun, but your electronics keep your room aglow like Christmas, you might need Light Dims.
LASIK: If you're constantly cursing, "The halos! The halos!" You might need Light Dims.
TRAVEL: Why in the name of Thor do hotel alarm clocks have such bright numbers? If you've ever unplugged the hotel alarm clock, and then overslept, you might need Light Dims. (Yes, they're removable with no sticky residue!)
KIDS: As the famous book says, Go the *bleep* to Sleep! If your kids use the bright LEDs on their electronics as an excuse to crawl into your bed at night, you might need Light Dims.
ZOMBIES: If you want to remain unseen in the woods at night (and charge your iPhone with a solar charger by day, 'natch!), you might need Light Dims.
Light Dims are super simple to use, totally removable, and don't interfere with the aesthetics of your favorite electronics. The regular Light Dims simply dim the light produced by the LED and the Blackout ones completely shield the light so it can blink all it wants without bothering you. Need a little dimmer, but not totally black? Regular Light Dims stack for additional dimming. Send us your Action Shots so we can see what you're doing with Light Dims!
Product Specifications
- Block some or all of the bright lights from LEDs
- Prevent headaches, sleep better, and be less annoyed by blinking lights
- Removable: Bring some when you travel to dim the hotel alarm clock!
- Two strengths: Regular (dimmed) and Blackout (100% blocked)

Historic Elgin Hotel listed for sale
News editor
One of Marion's most revered landmarks, the Historic Elgin Hotel, is for sale. The property is listed with J.P. Weigand & Sons Realtors of Wichita.
Owners Jim and Nancy Cloutier bought the Elgin in 2006 when it was an apartment building. They restored it to its 1870s glory, converting the first and second floors into a bed and breakfast and the third floor into their family residence.
The description with the listing says the cost of the renovation was $1.9 million. It lists an asking price of $750,000 for the 15,204 square-foot building.
The Elgin was built in 1876 and operated as a hotel until the 1950s. In the 1970s, it was renovated into apartments, which remained until the building's restoration.
The Cloutiers could not be reached for comment. The full listing can be found online at http://www.weigandcommerical.com.

Thanks for the info. I picked up a used DC21 and this is great because I have 67mm lens from Tetra housings. I completed the project in one try pretty much on the kitchen table. Just wanted to add that instead of the template I just took all 6 screws out and removed the plastic face plate from the housing. Placed the stepping ring (after sawing) on the table and put face plate on top and marked holes on ring. All a bit tedious but a great DIY modification that's easy on the wallet for a change.
I'm glad it worked for you. I was reluctant to remove all 6 screws as I didn't want to break the seal on the port, but testing that it's still waterproof without the camera in it can easily get around this concern.
If anyone is going to use this modification with just the internal flash (like me), then by moving the diffuser to the end of the close-up lenses, the shadow of the lenses are almost, if not completely reduced. I did mine by using a piece of elastic (from a flight luggage label) and drilling another hole in the diffuser. The next two images show what I mean. Plus here is a shot of the technique being used.

Caroline Shaw and Quenotte des Lacs—April 20, 2012
From: Judge Rob Gage
That was a somewhat unusual course, in that it had almost no oxers! That's not your fault, you can only do what you are asked….and you and your horse DID IT GREAT! I loved your even pace throughout that kind of long course. I noticed she didn't do any flying changes….as she cross cantered all the way from 2-3 and again between 3-4. I'll address that later. You "chipped" to that log option fence #6, but I wanted to compliment you about that. Sometimes, we all miss and we have a millisecond to decide "the lesser of two evils." You absolutely made the right choice to "chip" rather than take the long option and she still jumped it in great form.
Were you an equitation rider when you were younger? I was really impressed with your smooth release and your refined body control over the jumps. Listen, I really don't have any major criticisms, you were both really good.
OK…let's get into how to teach a horse to do flying changes. A flying change is actually a "skip" like when you were younger, and skipped across the ground. A horse needs to temporarily lift all 4 feet off the ground. Here's what I like to do. I set 2 poles about a foot apart set at a slight angle to the upcoming fence or wall. The two poles helps the horse to get all 4 feet up in the air and the upcoming wall/fence force the horse to turn immediately after the poles. To be honest, you (the rider) need to initiate the turn a moment BEFORE the poles! I set 2 poles together on each side of the ring, so I can make a figure 8 pattern, and practice the lead changes in each direction. You know they are "getting it" when they start the flying change before going over the poles.
Congratulations! I really like you and your horse. Hope to see more of you on judgemyride.net.
From: Judge Carol Dean-Porter
I am a big Selle Francais fan and this one is no exception. She marches into the ring like a pro and sets about doing her job in a confident and balanced manner. I have the feeling these jumps are pretty easy for her. I like the way she maintains her even pace uphill, downhill turning left and turning right. She is careful about the jumps and stays light in your hand. I like the simple Dee snaffle.
She seems cheerful and fun to ride! Yes, you cross cantered, but that is not a huge error for your discipline. I always remember that "Touch of Class" won the gold medal in the 1984 Olympics, cross cantering the entire course! If you can teach her to change her leads, more power to you and you will find that the distances come up easier and the turns are easier when not cross cantering. Rob gave you some hints as to training the lead change.
Your lower leg is quite good. This is your base of support and permits you to control your body in the air well. You start off at the trot somewhat upright and behind her motion. Relax and have fun!
Your distance to number 3 might have been a bit long, hard to tell with the other jumps in the way. The rest of the course you are very accurate and ride right to the base. You probably even chipped a bit on the log fence number 6, which is just fine. I prefer the deep distance to the long one ANY day! She really uses her hind end well over that fence.
Overall, great job and I think this horse is a wonderful match for you!

Knowledge is traditionally defined as "justified true belief."
Nailing down which beliefs really count as knowledge is sometimes tricky and requires a lot of qualifiers.
Consider a factual claim X, such as "The moon is made of green cheese." If I say that I "know" X is true, we may assume from that I also "believe" that X is true (unless I am lying or deluded about my own beliefs, which is rare). However, my statement is wrong in two ways. First, X is false (the moon is not made of green cheese), so I am factually incorrect about my belief. Second, I cannot truly be said to know X, because one can only know a true statement.
However, even if one believes something that happens to be true, this isn't necessarily knowledge. Suppose you walk onto a crowded subway, and you pick out a stranger from the crowd, and you tell yourself: "I believe that his name is John Smith." Now let us further suppose that the stranger happens to actually be named John Smith. This is purely coincidental, because John Smith happens to be a common name and you had no way of knowing what the stranger's name was. The question is, did you really "know" that his name was John Smith?
Philosophers would say no. Even a true belief cannot be properly termed "knowledge" unless there is a good reason to believe the statement. This is why the word "justified" is included in the definition.

The labor theory of value
By Paul Greenberg
http://www.JewishWorldReview.com |
The old man had long ago given up fixing shoes and tried other businesses, but always at the same location, and with many of the same customers. But he never found any other work that gave him as much satisfaction as putting new soles on a pair of old uppers. Or putting a pair of Cat's Paw heels on shoes that still had a lot of wear left, and doing it neatly, surely, carefully to last.

The Center for Rural Affairs estimates that as much as half of all business transactions will move to the Internet over the next decade. It also suggests that people in rural areas need to grow a new generation of farm and small business cooperatives in this cyber age.
One such business, a distribution company called Iowa's Pantry, has been operating on the Web since August 1999. It has about 60 suppliers, many of them farmers.
For $100 you can list with the distributor to sell your products online. Contact Iowa's Pantry, Dept. FIN, 1815 White Tail Rd., Decorah, IA 52101, 888/387-0013, www.iowaspantry.com or circle 199.

I've been running a water cooling rig for ~8-10 month and have started noticing some white particulate in the reservoir the last couple times I topped it off. I've never had a water loop before and wanted to see if anyone with more experience might have any ideas as to what this might be and if it's harmful to the system? Post with parts used in loop; I would think since i got everything from the same company that there shouldn't be any corrosion issues but I can't find out the material used in the waterblock that's built into my graphics card so I can't rule it out.
The particles don't really show up when I take a picture of the reservoir but I'd estimate them at ~.1-.5mm in size and white or off white in color.

Re: Water cooling question
IT happens. I tend to change my fluid every year or so. Tubing will express some of the chemicals over time. It's mostly harmless but obviously you don't want it building up in large amounts in the fluid.
You can run some vinegar solution or more specifically whatever your brand suggests you use to clean the loop to help clean things up a bit.

Re: Water cooling question
In that case I'll probably wait a couple months till I have the money to go SLI since I'd have to drain the loop then anyway. Thanks for the help.

Tackling the long-time nuisance of American submarines off its coastal waters, China is deploying drones to its Navy ships.
While not a new development on its own, there are reports of increased drone deployment to the PLA's ships, and a heightened attack against U.S. drone contractors.
UPI reports Chinese hackers have ramped up their barrage of infected emails to glean as much information about the Pentagon's UAV strategy and development as they can.
It's no secret that the Chinese military is in the habit of copying foreign hardware, and while drone technology was previously limited to the U.S. and its allies — that's over.
China began developing UAVs in the 1960s just as several American AQM-34G - R models were lost over the Chinese mainland. Spy Flight says one drone was recovered by the Chinese, who maintain they shot it down.
In 1969 China began reverse engineering the drone at the Beijing Institute of Aeronautics and Astronautics in an eager bid to figure out the American technology and use it for themselves.
By 1972 the U.S. drone was copied into the WuZhen-5. And when China invaded Vietnam during the war of 1979, China's first drone was used to successfully collect visual intelligence — a chilling example of how good China is at counterfeiting military hardware.
But being based on a drone from the 1960s, the Wuzhen-5 is nowhere near as sophisticated as U.S. drones.
And that's why China would be keen to inspect the American RQ-170 Sentinel stealth drone, which Tehran was able to capture last year.
The "Beast of Kandahar" went down to much Iranian fanfare, and after doubts about the drone's capture were put to rest by its display on PressTV, questions of how great a loss its capture is to U.S. intelligence continue to linger.
There was speculation in February the drone went down with its data still intact and the folks at DARPA told Wired that there is little doubt the Russians and the Chinese were brought in to help with reverse engineering the advanced American aircraft.
When Beijing gets around to using the Sentinel's technology in its own fleet of drones, there is little doubt it will be used to patrol China's vast coastline and maritime territory using the genetic algorithms already employed by its older drones to hunt for submarines.
American subs in Asian waters are a definite burr in Beijing's saddle and are the one true soft spot in the Asian nation's military buildup. The U.S. routinely has 10 forward deployed subs in the world's oceans at any given time and in the event of Chinese hostilities they would slip into the area as quietly as possible.
China's best defense would be its unique algorithms in a fleet of drones, patrolling the coast, using information from sonar buoys to track the American subs. Whether the Sentinel's technology will aid the Chines in their efforts has yet to be seen.

Yesterday was certainly a big day for the venerable Dutch auto industry.
Chrysler, the once undeniably American company that suffered through a decadelong marriage to a German, then had a taxpayer-supported shotgun wedding with an Italian, is settling down in the Netherlands.
It's now part of Fiat Chrysler Automobiles, a Dutch holding company with a tax domicile in the UK, a stock listing in New York and a three-letter logo that I hope no one spent more than nine seconds creating.
FCA — which Wikipedia tells me could also refer to the Fellowship of Christian Athletes, the Farm Credit Administration or the Ferengi Commerce Authority from TV's "Star Trek: The Next Generation" — will soon introduce its newest vehicles, the Dutch Durango and Fiat Vijfhonderd. A hastily assembled commercial airing during the Super Bowl on Sunday will kick off a new advertising campaign: "Imported from Utrecht."
Actually, that's not true. Little will visibly change as a result of all this.
Chrysler will keep its headquarters in Michigan. Fiat will still be based in Italy. CEO Sergio Marchionne, an Italian-Canadian, will still always wear black sweaters and feud with his German archrival, Volkswagen Chairman Ferdinand Piech.
But it raises a couple questions: What nationality is Chrysler now?
Is it Dutch? Italian? Italian-American?
And another: Is there still a Detroit 3? Or is Motown down -- as some argued during the DaimlerChrysler era -- to just two?
The answers might seem trivial. But they do matter in terms of pride. They affect how Automotive News and other media outlets describe Chrysler. They matter to many Americans who feel their tax money was used to save a foreign car company.
This is an industry that debates whether a Toyota Camry should be considered Japanese just because that's where the company that builds it is based, even though it's assembled in Kentucky by workers who spend their paychecks at local businesses. The Camry has less foreign content than every vehicle sold in the United States except the Ford F-150, according to the 2013 Cars.com American-Made index.
Meanwhile, the top-selling "American" car, the Ford Fusion, is made mostly in Mexico.
There are few clear answers anymore, and Chrysler just made things even more confusing.

Wednesday evening, a month after the new SPARC servers T5 & M5 launch in Paris, the french Solaris users group, get together to get the latest from Oracle experts on SPARC T5 & M5, Oracle Virtual Network, as well as the new enhancements inside Solaris 11.1 for Oracle Database. They also came to share their projects experiences and lessons learn, leveraging Solaris features : René Garcia Vallina from PSA, did a deep dive on ZFS internal and best practices around SAP deployment and Bruno Philippe explained how he managed to consolidate 100 Solaris servers into 6 thanks to Solaris 11 specific features.
It was very interesting to see all the value that an operating system like Solaris can bring. As of today, operating systems are often deeply hidden in the bottom layers of the IT stack, and we tend to forget that this is a key layer to leverage all the hardware innovations (being new CPUs cores, SSD storage, large memory subsystems,....) and expose them to the applications layers (being Databases, Java application servers,...). Solaris is going even further than most operating systems, around performances (will get back to that point), observability (with DTrace), reliability (predictive self healing,...), and virtualization (Solaris ZFS, Solaris Zones & Solaris Network Virtualization, also known as project "crossbow").
All of those unique features are bringing even more values and benefits for IT management and operations in a time of cost optimization and efficiency. And during this event, this was something that we could get from all the presentations and exchanges.
Solaris and SPARC T5 & M5
As Eric Duminy explained in the introduction of his session on the new SPARC T5 & M5, we are looking into new paradigm of CPU design and associated systems. Following Moor's law, we are using transistors in completely new ways. This is no more a run for frequency, if you want to achieve performance gain, you need more. You need to bring application features directly at CPU and Operating System level. Looking at SPARC T5, we are talking about a 16 cores, 8 threads/core processor, with up to 8x sockets, 4 TB RAM, SPARC T5-8 server in only 8 rack units ! This mean also, 128 cores and 1024 threads, and even more for the M5-32, with up to 192 cores, 1536 threads, 32 TB RAM ! That's why the operating system is a key piece that needs to be able to handle such systems efficiently : ability to scale to that level, ability to place the process threads and associated memory on the right cores to avoid context switch, ability to manage the memory to feed the cores at the right pace.... This is all what we have done inside Solaris, and even more with Solaris 11.1 to leverage all this new SPARC T5 & M5 servers, and get the results that we announced a month ago at the launch.
Of course we don't stop there. To get the best out of the
infrastructure, we are designing at CPU, system and Solaris level to
optimize for the application, starting at the database level.This is what Karim Berrah covered in his session.
Solaris 11.1 unique optimizations for Oracle Database
Karim's explained first the reasoning behind the complete new virtual memory management of Solaris 11.1, something that benefits directly to Oracle Database for the PGA and SGA allocation. You will experience it directly at database startup (twice faster !). The new virtual memory system will also benefit to ALL your applications, just looking for example at the mmap() function which is now x45 faster (this is what is used for all the shared libraries). Beyond performances, optimizations have been made on security, audit, and management. For example, with the up coming new release of Oracle Database, you will be able to dynamically resize your SGA and also get greater visibility for the DBA in datapath performances thanks to a new DTrace table directly available inside the database: a tight integration between Oracle DB and Solaris unique features.
Alain Chereau one of our performance guru from EMEA Oracle Solution Center provided his foresight and expertise. He especially reminded that the performance is achieve when ALL the layers work well together, and that "your OS choice has an
impact on the DB and reverse. Something to remember for your critical applications." Alain closed the session with a final advice on best use of SSD for Oracle DB and Solaris ZFS. In short, SSD are align on 4k block. For Oracle DB, starting with 220.127.116.11, redolog can write in 4k block. This needs to be specify at redolog creation on the record size setting. For Solaris, ZFS knows about SSD and directly adapt. That's the reason why putting ZFS secondary cache on SSD (readzilla) is a very good idea, and a way to avoid bad behavior introduced by new "blind" storage tiering when combined with ZFS. Just put SSD drives for ZFS secondary cache directly inside your T5 or M5 servers and you are done. This is an important topic, as even if a majority of customers are running Oracle Database on ASM on production to get the benefit of grid and Oracle RAC security and scalability, that maybe different for development environments. As a matter of fact, for development systems most customers are leveraging Solaris ZFS and its compression and infinite clone and snapshot functions.
This brings me to René's session on SAP on ZFS...
Lessons learn from deploying SAP on ZFS
Clearly one of the most technical session of this event. Congratulation to René for a very clear explanation on ZFS allocation mechanisms and algorithm policies. I will start by René's conclusion : "Don't follow your ISV (SAP in this case) recommendations blindly". In fact, PSA was experiencing performances degradation and constant I/O activity even with very few transactions on application side. This was due to the fact that SAP recommends to use the SAP Data filesystem at more than 90% ! A very bad idea when you put your data on a Copy-on-Write (COW) filesystem like ZFS... Where I always recommend to keep around 20% of free space to allow for the COW operations to take place ! That's of course the new rule for SAP deployment at PSA.
So if you already have ZFS deployed with this rule in place, you don't have to read further, just keep doing it and move directly to the next topic... otherwise you maybe facing currently some performance problems as well. To identify which of your ZFS pools are facing this situation, René provided a nice dtrace command that will tell you :
# dtrace -qn 'fbt::zio_gang_tree_issue:entry { @[pid]=count(); }' -c 'sleep 60'
Then to solve the problem, you understand that you need to add free space to enable the COW operation (in one shot). The best way would be to add a vdev (for more details: Oracle Solaris ZFS: A Closer Look at Vdevs and Performance). You could also use a zfs replace with a bigger vdev, but that's not the best option in the long run. If you go through a whole modification cycle of the content of the pool, your zpool will "defragement" by itself. If you want to "defragment" the zfs pool immediatly, if you have a Database, you can do it through "alter table move" operations (special thank to Alain Chereau for the tip). For standard files, you need to copy them and rename them back, or best, do a zfs send | zfs receive to another free zpool and you are done.
From 100 Servers to 6 thanks to Solaris 11
Last but not least, we also had another deep dive session during this event, with live demo ! Thanks to Bruno Philippe, President of the French Solaris Users Group, who shared with us his project of consolidating 100 servers, going from Solaris 8 to Solaris 10 into 6 servers with minimal to no business impact allow ! Bruno achieved his project thanks to Solaris 11 unique new feature : Solaris network virtualization, combine with Solaris Zones P2V and V2V, and SPARC Hardware hypervisor (Oracle VM for SPARC, known also as "LDOM", or Logical Domain).I invite you to visit Bruno's blog for more details : Link Aggregations and VLAN Configurations for your consolidation (Solaris 11 and Solaris Zone)
Awaiting his next entry explaining the detail of the V2V and P2V operations that he demonstrated to us live on his laptop through a Solaris 11 x86 VBOX image.
I hope to see you on the up coming Solaris and SPARC event to share your feedback and experience with us.
The up coming Paris events will take place on June 4th, for Datacenter Virtualization, focus on storage and network, and July 4th for a special session on new SPARC servers and their business impact.

The Same systems used to fly U.S. Air Force Predator drone airplanes from computer terminals thousands of miles away could become the next big thing in agriculture.
Although farmers aren't likely to be driving tractors, sprayers and combines by remote control anytime soon, rudimentary versions of the communications technology that would make this possible are likely to become standard features in the not-too-distant future.
For now, this technology will be used to report everything from equipment location and travel speed to complete machine operation information, including real-time fuel and sprayer/combine tank levels. The potential payoffs for using these systems include better machine use efficiency, improved maintenance and reduced downtime.
The technology that makes these systems possible is called telemetry, or telematics. Simply put, telemetry captures and reports information automatically from afar, typically to a central computer server. If you close the loop by communicating back to the device in question, a tractor, for example, you have the makings of a Predator-like remote-controlled system. Cutting-edge two-way telemetry systems that allow engine electronics to be automatically diagnosed and fixed remotely already are a reality.
Telemetry systems that report engine functions and other key information will be widely available in the next few years.
"Telemetry is the next big technology that will be adopted in agriculture," says Mark Moore, head of AGCO's worldwide telemetry development effort. "Adoption will be quite rapid."
That's possible in part because technologies used in telemetry systems are already in use in other industries, including transportation, construction and mining. Off-the-shelf components are ready and available to slap into the cab.
The challenge for telemetry providers — and a major factor behind how fast this technology will take off — is to make sure its value justifies its cost.
"The technological barriers [to offering telemetry systems] aren't there," Moore says. "The question is, how do we apply telemetry so the customer can make money out of it? Unfortunately, there is no hard-and-fast rule that if you buy telemetry you will save 5% on your running costs."
"Farmers aren't interested in nice-to-have systems," adds Mark Bittner, head of telematics for Topcon Positioning Systems. "They are interested in something that is must-have, that can reduce costs and improve productivity."
OnStar template
OnStar is perhaps the most widely known telemetry system in the U.S. today. And the agriculture systems in the works or currently on the shelf largely mimic OnStar's capabilities.
OnStar's in-vehicle safety, security and information services system is a template for the technology and services being deployed in agriculture. It uses cellular communications, GPS satellites and operations data from the vehicle's CANbus to link vehicles to a central computer server and service center. Using this system, in an average month, OnStar unlocks doors on 62,000 cars, conducts remote diagnostics on 54,000 vehicles and coordinates 2,000 automatic crash responses.
Agricultural telemetry systems essentially use the same technologies, minus some of the frills such as service center operators to contact the user in case of an accident. Instead, information will be delivered via Web sites, which will capture and display the parameters the owner wants to track. The information flow will be supplemented by automated cell phone, e-mail and/or text alerts when preset alarms (tied to engine error codes, required maintenance or low fuel tank levels, for example) go off.
In addition to receiving automated alerts, ag telemetry customers will be able to access machine data on a password-protected Web site via a Web-enabled cell phone or PC. Some are expected to have graphic interfaces that mimic an implement's monitor. Tools to analyze trends in key operating parameters are another possible feature.
Ag telemetry ramps up
By the looks of things, you will have a lot of agricultural telemetry service offerings from which to choose in the next couple of years. Virtually all the major original equipment manufacturers (OEMs), as well as guidance system companies and others, say they are developing telemetry systems for agriculture. Some systems already have been on the market a few months.
For example, both Topcon and Trimble introduced telemetry products in 2008. Companies such as LOFA Industries and TeleNav, which focus on transportation, industrial engine and other markets, also offer plug-and-play telemetry systems that can be used in ag equipment.
Among OEMs, Deere is the first to announce a new telemetry system. It plans to begin offering two new telemetry products in 2009. They replace its JDLink Machine Messenger system, a telemetry system Deere introduced in 2002. The company withdrew Machine Messenger from the market early last year when the Federal Communications Commission allowed the analog cellular communications system on which it was based to be shut down.
Other OEMs say they will have systems on the market within a year or two. Other providers are likely, too, including Leica, which announced it was pilot-testing a telemetry system in 2008. (See "Remote-controlled farming," September 2008.)
"We probably are one or two years away from introducing something," says Chris Brubaker, precision farming product manager for New Holland. "First, we really have to have a solid value story for the customer."
The cost/value equation
Although John Deere says its JDLink Machine Messenger product was successful, its competitors say it presents a cautionary tale about a technology that was too costly for what it offered, in part because it was ahead of its time.
When introduced in 2002, Machine Messenger, which was available for 20 series tractors with cabs, had a $2,495 hardware price tag, plus a $495 annual service fee. It provided information such as a tractor's location, engine operating state, and total idling, working and transporting time. It also kept a log listing all "warning" and "stop engine" alerts generated by the tractor's computer.
"JDLink Machine Messenger was very successful," says Chrissie Cartmell of Deere's Ag Management Solutions group. "Folks that used it liked it."
Since 2002, the hardware costs associated with telemetry systems have plummeted.
Current products
The price of current systems centers around $1,000/machine, plus a monthly service fee.
The least-expensive systems generally provide information derived from GPS data collected from built-in GPS receivers. Some systems supplement this data with limited machine operation data collected from analog sensors connected to fuel, temperature, pressure, tank and other dial-type gauges. More expensive options also offer GPS-related data, plus data collected from the machine's CANbus system.
GPS-related information allows tracking of a machine's path and speed over time, including current location and speed, as well as operating hours. These systems typically send the user an alert when a machine leaves a designated area.
CANbus telemetry systems collect data over time so a producer can analyze trends that can help improve operating efficiencies and warn of impending breakdowns. Alarms also can be set to alert the user when key operating parameters go out of bounds, when regular maintenance is needed, fuel or spray tanks are at low levels, etc.
Typically, telemetry system hardware includes a black box module containing a GPS receiver, a small computer and a cellular data card, plus an external GPS antenna. CANbus systems are designed to be plugged directly into the vehicle's CANbus.
The Topcon Tierra system, which offers several hardware options and service levels, costs $300 to $1,500/machine for hardware, plus a service fee of $20 to $50/month.
"We are an all-makes solution," Bittner says. "We don't care if the machine is a Deere or a Fendt or a Case. We work seamlessly on all makes."

Trimble's Ag Manager system focuses primarily on location-derived information from the GPS device built into its CrossCheck communications module. It also can capture and report data from up to four digital sensors and has the ability to send and receive short text messages. Ag Manager costs $695 for hardware, plus a monthly service fee of $24.95 to $49.95.

John Deere will introduce two telemetry products in the spring of 2009, according to Cartmell. JDLink Select is a GPS-based all-makes, all-models solution that offers machine information such as location and hours. It also allows the user to manage equipment maintenance and set a geofence or curfew alert to notify the owner that the machine has been started or moved outside of the user-defined settings.

The TeleNav Asset Tracker is the low-cost leader among these offerings. For $199.95, plus $19.95 a month, this battery-powered GPS-based device tracks the current vehicle location, as well as its recent movements. Alerts can be set to let the user know when vehicles enter or leave specified areas. Hard-wired models also are available.

Challenges, payoffs
GPS-based systems generally are brand neutral, but those providing CANbus information face compatibility challenges. This lack of universality may present challenges to telemetry customers with multi-branded equipment.
Ultimately, how rapidly farmers adopt telemetry systems will depend on how much value they can derive from them. Proponents say that improved logistics, reduced downtime and better machine longevity through improved maintenance will more than pay for the cost of a telemetry system.
"There is a lot of potential here," says Moore of AGCO. "We just need to get through the initial adoption barrier and get customers thinking about the possibilities. If we do it right, it will be the next big technology that agriculture adopts. But if we make it too expensive or complicated, it will stay on the shelf."

I know this is late but better late than never!
Jevon and I went to the Raptors Red Party Remix back in late January, or as I would like to call it: my last encounter with Ed Davis as a Raptor.
The Ballroom Bowl had two floors of fun. The main floor had bowling lanes and pool tables. The upper level had a photo section, a ping pong table, the main stage and the big bar.
Matt Devlin came out with the welcoming address and the introduction of the players. After that, the boys went to each of their little sections that they were placed to entertain. Ed Davis was at the ping pong tables. Terrence Ross was at the pool tables. Amir Johnson, John Lucas III and Landry Fields were at the bowling lanes.
My personal highlight of the night was playing Ed Davis at ping pong. Honestly, I'm not that great at ping pong but I tried my best anyway! A clip of it will be in the video below! Many Raptors tweeters were out and about that night and it was great to see all of their faces:
@RyanJHTurvey + his lovely wife
…and more!
Yes, the video includes a little bit about how we will be at the Raptors vs. Grizzlies game (which is already up in the blog) but our message is still valid! When we are at Raptors games we will be going around talking to the fans so if you are there and so are we, come and talk with us! We'd love to have more Raptors fans in our videos so come and be a part of the DNB Fan Zone!
We have a new You-Tube Channel to so subscribe there for all the latest videos from the DNB. We have big plans for adding lots more video stuff for the DNB so stay tuned.

22 August 2013 at 1.00pm | Comment on this article
Composer Philip Venables has been announced as the first Doctoral Composer-in-Residence at the Guildhall School of Music and Drama, the result of a collaboration between the conservatoire and the Royal Opera House.
The new position is one of the first examples of an opera company and conservatoire joining forces to offer a 'Composer-in-Residence' studentship which leads to a doctoral degree, a path long established in orchestral music.
Philip will be supervised by Guildhall School's Head of Composition, Dr Julian Philips, who was the first ever Composer-in-Residence at Glyndebourne. His new opera How The Whale Became, an adaptation of a collection of stories by Ted Hughes, receives its world premiere at the Royal Opera House in December 2013.
The studentship is fully-funded by the Guildhall School and will take on a new Composer-in-Residence every two years. Composers will have the chance to present a major work in the third year of study in the Linbury Studio Theatre at Covent Garden.
Philip previously studied at Cambridge University and the Royal Academy of Music. He holds a London Symphony Orchestra Soundhub residency at LSO St Luke's. He has also composed works performed by the BBC Philharmonic, LSO, London Sinfonietta and at the Bregenz Festival among others. His music is often concerned with violence and politics.
Philip said:
'I'm really excited about starting work on this opera with the Royal Opera House and the Guildhall School - it's a potential game changer for me, and a chance, in a structured and supported way, to really explore what opera means to me, to be completely inventive, bold and daring and to present the results of that on a high-profile stage.'
Associate Director of Opera at the ROH, John Fulljames, said:
'We're delighted that Philip Venables is joining The Royal Opera and Guildhall School on our first joint composer residency. Philip's work has increasingly embraced collaborative and multi-media practice and so it is a natural step for him to now research and write music theatre with us. We are looking forward to developing and making work with him.'

As a steady, just-hard-enough-to-irritate-you rain fell in Trenton Friday night, the Jones Senior Trojans and Southside Seahawks were locked into a fierce battle on the football field.
TRENTON � As a steady, just-hard-enough-to-irritate-you rain fell in Trenton Friday night, the Jones Senior Trojans and Southside Seahawks were locked into a fierce battle on the football field.
In a game that came down to the final play, Jones Senior fell eight yards short of victory.
�It was a tough game and with the wet field that didn�t benefit either one of us, it made it tougher,� Jones Senior coach John Davis said. �You know with 18 kids dressed out from the whole student body, it�s great to see them never quit and keep fighting.�
Glen White quarterbacked the Trojans� final drive after the defense had forced the Seahawks to punt.
White led the offense all the way down to the 8-yard line, with 3.1 seconds left and one last hurrah.
White scrambled and launched a pass to the back right corner of the endzone that was batted to the ground by a Southside defender, ending the comeback attempt, and dropping the Trojans to 0-8.
Jones Senior (0-8, 0-2 Coastal Plains Conference) surrendered 30 points to the visitors from Chocowinity, but held their own by putting up a 20 spot.
One of the biggest plays of the game that came back to doom the Trojans occurred just before the halftime buzzer.
The Trojans were marching at the Southside 15-yard line with seconds remaining when quarterback Javon Andrews found Zac Brooks on an out route.
Brooks carried the ball to the end zone and appeared to hit the pylon on a dive before careening out of bounds.
The men in stripes didn�t see it that way and marked the ball on the 1-yard line.
The Seahawks� defense then stuffed a quarterback sneak attempt by Andrews, forcing time to run out on the Trojans.
�We played much better in the second half, but time just ran out on us,� Davis said. �Southside played well though, they are well-coached and a very good running team.�
The Seahawks (3-5, 1-1) used a trio of hard-running backs for the brunt of their offensive force.
Lawrence Brown and Isaac Harrell dashed right and left, as Dylan Lewis was used in power running situations.
Brown scored a pair of touchdowns, as Harrell, Lewis and quarterback Johnny Sullivan added one apiece.
Neither team utilized a kicker and went for two points on each score.
�We needed a good morale boost and this game gave us that,� Southside coach Jeff Carrow said. �Our offense was clicking pretty well, our defense just needs some work.�
The Trojans travel to Northside (Pinetown) next week, while Southside heads to East Carteret.

Teams from Sweden, Canada, the United States, Australia and New Zealand are getting ready to do battle on the Waitemata Harbour for the illustrious Harken Cup!
It's the first time a Canadian team has travelled to Auckland to compete and it comes from the inclusion of a formal match racing programme at the Royal Vancouver Yacht Club. The young team has excelled on the water and formed the 'Northwest Youth Racing Team' helmed by 14 year old Richard Minielly just last year. All five attend high schools in Vancouver and compete in various racing classes with the Royal Vancouver Yacht Club. Although young, the team has considerable sailing experience for their age, and each member has individually placed in the top three spots in a number of regattas. Since the Northwest Youth Racing Team was formed in 2012 it has already had success in the RVYC Kintec match racing events, placing eighth, and sixth in their first two regattas. We look forward to seeing if all the classroom seminars during their winter have paid off!
This is also the first time that three American teams will compete in this competition. Charlie Lalumiere - Portland Yacht Club, Christophe Killian - Balboa Yacht Club, and Will Holz, current winner of the Rose Cup, a US National Youth Match Racing Championship, representing the Chicago Yacht Club.
The highest ranked young sailor and competing for the first time in the Elliott 7's, is Sam Gilmour representing the Royal Freshwater Bay Yacht Club, Perth. Gilmour at just 19 years of age has an impressive ranking at 101 which includes a fifth placing at the Warren Jones Regatta in Perth, fifth at the 2012 Governor's Cup, USA and a win at last week's Centreport Youth International held in Wellington.
Next highest ranked at 200 is Adam Middleton representing the Royal Port Nicholson Yacht Club, who was part of Gilmour's winning crew last week. Middleton was also part of the 2012 winning Governor's Cup crew helmed by Tim Coltman and he finished eighth at this event last year and seventh in 2011. Will it be third time lucky for Coltman this week?
It is fantastic to see two all-female teams competing at this year's championships; Hannah Osborne - Royal New Zealand Yacht Squadron and Claudia Pierce, Kawau Island Yacht Club. Both are current members of the RNZYS Lion Foundation Youth Training Programme and also skippers.
20 year old Claudia and her Infinity Racing Team are looking forward to this week's match racing with the hope of a podium finish, "It's a prestigious youth event, with a high calibre of teams. I am aiming to improve my ranking, race some great teams and hopefully make the podium."
Last year's winner Chris Steele was on the entry list but had to withdraw after he received a rather amazing invitation to compete at the Red Bull Youth America's Cup Trials now on in San Francisco. Grabbing Chris' spot is fellow Lion Foundation Youth Training Programme skipper Scott Barnes who also competed at the Centreport Youth International placing fifth overall.
The Harken Youth International Match Racing Championships is sailed in the Squadron's fleet of 10 Elliott 7 metre yachts used by the Youth Training Programme. Coach of the RNZYS Lion Foundation Youth Training Programme, Guy Pilkington, commented, "We are ready to go, the boats are in great condition and a few of the teams have arrived in Auckland early to train. We are really pleased to have 14 teams competing this year; I am really looking forward to a great regatta."
Race Officer for the event Megan Kensington is looking forward to the week, "The forecast is mixed at this stage, with some light and some windier conditions forecast, which should give us a good mix of racing. The tides are being nice to us this year. The format is for a single round robin, quarter finals for the top 8 teams, semi-finals and finals. My team and I are looking forward to it and ready for some great racing."
All teams will have their official practice day on Wednesday and Opening Ceremony in the evening. Racing begins at 10am on Thursday

In Pcompress, I have implemented a variant of the rolling hash based Content Defined Chunking that provides both deduplication accuracy and high performance. This post attempts to explain the chunking process, covers the chunking computations that are done in Pcompress and then talks about the new optimizations for very fast sliding window chunking (on the order of 500MB/s to 600MB/s throughput depending on processor).
Data Deduplication requires splitting a data stream into chunks and then searching for duplicate chunks. Once duplicates are found only one copy of the duplicate is stored and the remaining chunks are references to that copy. The splitting of data into chunks appears to be an ordinary process but is crucial to finding duplicates effectively. The simplest is of course splitting data into fixed size blocks. It is screaming fast, requiring virtually no processing. It however comes with the limitation of the data shifting problem.
The diagram below illustrates the problem. The two 64-character patterns are mostly similar with only two characters differing. Initially fixed-block chunking provides good duplicate detection. However the insertion of a single character at the beginning shifts the entire data while chunk boundaries are fixed. So no duplicates are found even though the patterns are mostly similar.
The diagram shows insertion, but the same thing can happen for deletion. In general with static chunking duplicate detection is lost after the point where insertion or deletion has taken place.
In order to deal with this, most dedupe solutions use content defined chunking that mark cut points based on patterns in the data. So if the data patterns shift the cut points also shift with them. The diagram below illustrates.
The chunks are split based on patterns in data so they are of variable length (but average size is close to the desired length). Since the chunk boundaries shift along with the data patterns, duplicates are still found. Only the modified chunks are unique.
The Rolling Hash computation
Now the question comes as to what data patterns to look out for when determining the chunk boundaries or cut points? The common technique is to compute a hash value of a few consecutive bytes at every byte position in the data stream. If the hash value matches a certain predefined pattern we can declare a chunk boundary at that position. To do this computation efficiently a technique called the rolling hash was devised. It uses a sliding window that scans over the data bytes and provides a hash value at each point. The hash value at position I can be cheaply computed from the hash at position I-1. In other words where 'n' is the window size and represents the window bytes at byte position 'i'. In mathematical terms this is a recurrence relation. Rolling hashes have been used in contexts like Rabin-Karp substring search and Rsync. Today they are used extensively in chunk splitting in the context of data deduplication.
One of the common rolling hashes used in Data Deduplication is Rabin Fingerprinting devised originally by Turing award winner Michael O. Rabin in his seminal paper titled "Fingerprinting By Random Polynomials". The mathematically inclined will enjoy reading it. There are other rolling hash techniques such as the one used in Rsync, the TTTD algorithm devised by HP, the FBC algorithm etc.
While I am not so much of a mathematically inclined person I still needed a good rolling hash in order to do content defined chunking in Pcompress. After looking at various implementations like the one in LBFS and few other open-source software like n-gram hashing, I came up with an approach that worked well and produced average chunk sizes close to the desired value.
I used a small sliding window of 16 bytes that produces a 64-bit fingerprint at each byte position requiring an addition, subtraction, multiplication and conditionally an XOR for each byte position. It would declare a chunk boundary if the bottom Y bits of the fingerprint were zero. The value of Y would depend on the average chunk size desired. For example for 4KB average size one would look for bottom 12 bits to be zero. The core of the approach is derived from Rabin Fingerprinting. A good description is here: http://www.infoarena.ro/blog/rolling-hash. The hashing approach is a multiplicative scheme of the form:
Where inbyte is Incoming byte into sliding window head, outbyte is outgoing byte from sliding window tail and . The PRIME number I am using is the same value used by Bulat Ziganishin in his SREP tool. Experimentation showed it to produce good results. In addition to this I precompute a table using the irreducible polynomial (represented in GF(2)) from LBFS. The outbyte is used to index the table and the value is XOR-ed with the hash value to produce the final fingerprint. I did some analysis of the chunking approach which is documented in two earlier posts. The results were good.
- Inside Content-Defined Chunking in Pcompress, part – 1
- Inside Content-Defined Chunking in Pcompress, part – 2
A window size of only 16 bytes will raise some eyebrows as typically much larger windows are used. LBFS for example used a 48-byte window and others have used even larger windows. However in practice, as is evident from the above analysis, this implementation does produce good results and the window size of 16 bytes allows an optimization as we will see below.
While addition, multiplication are extremely fast on modern processors, performance overheads remained. Even though I was using a small window of 16 bytes it still required performing computations over the entire series of bytes in order to find cut points. It is very much computationally expensive compared to the simple splitting of data into fixed-size chunks. A couple of optimizations are immediately apparent from the above hash formula:
- Since we are dealing with bytes it is possible to pre-compute a table for
- The MODULUS operation can be replaced with masking if it is a power of 2.
This gives some gains however the overhead of scanning the data and constantly updating a sliding window in memory remains. Eventually I implemented a couple of key new optimizations in Pcompress that made a significant difference:
- Since the sliding window is just 16 bytes it is possible to keep it entirely in a 128-bit SSE register.
- Since we have minimum and maximum limits for chunk sizes, it is possible to skip minlength – small constant bytes after a breakpoint is found and then start scanning. This provides for a significant improvement in performance by avoiding scanning majority of the data stream.
Experimentation with different types of data shows that the second optimization results in scanning only 28% to 40% of the data. The remaining data are just skipped. The minimum and maximum limits are used to retain a distribution of chunk sizes close to the average. Since rolling hash cut points below the minimum size are ignored it does not make sense to scan that data.
All these optimizations combined provide an average chunking throughput of 530 MB/s per core on my 2nd generation Core i5 running at 2.2 GHz. Of course faster, more recent processors will produce better results. The throughput also depends on the nature of the data. If the data has a very specific pattern that causes more large chunks to be produced the performance degrades (Think why this should be the case). This brings us to the worst case behaviour.
Worst Case performance profile
The worst case performance profile of the optimized chunking approach happens when all chunks produced are of the maximum size. That is the data is such that no breakpoints are produced resulting in a degeneration to the fixed block chunking behaviour at max chunksize of 64KB and at the cost of rolling hash computation overhead. In this case the majority of the data is scanned and computed, but how much ?
If we assume minimum chunk size of 3KB, maximum 64KB and 100MB data we will have chunks (considering worst case all max-length chunks). For every chunk of data will be skipped. In my current implementation the value of small constant is 256, though it can be smaller. So the actual skipped size is bytes. In total the number of skipped bytes will be bytes out of 100MB data. In percentage terms it is . In other words 95% of the data will be scanned degrading the performance by more than half.
Now the question is what kind of data will produce this worst case behaviour? If you have seen the rolling hash computation details in Pcompress above, the eventual fingerprint is computed via an XOR with a polynomial computation result from a table. Those values are non-zero and we check for breakpoints based on bottom 12 bits of the fingerprint being zero. So if the computed hash is zero the XOR will set the bits and bottom 12 bits will become non-zero. The hash will be zero if the data is zero. That is if we have a file of only zero bytes we will hit the worst case.
I created a zero byte file and tested this and got a throughput of 200 MB/s and all chunks of the max 64KB length. In real datasets zero byte regions can happen, however very large entirely zero byte files are uncommon, at least to my knowledge. One place having zero byte regions is VMDK/VDI files. So I tested on a virtual harddisk file of a Fedora 18 installation in VirtualBox and still got a majority of 4KB chunks but with a small peak at 64KB. The throughput was 490 MB/s with approx 41% of the data being scanned. So even a virtual harddisk file will have non-zero bytes inside like formatting markers. It is rare to get 100s of megabytes of files with only zero bytes. Finally from an overall deduplication perspective such files will be deduplicated maximally with almost 98% data reduction and final compression stage will also be extremely fast (only zero bytes). So even though chunking suffers, overall deduplication will be fast.
If you are interested to look at the implementation in Pcompress, it is here: https://github.com/moinakg/pcompress/blob/master/rabin/rabin_dedup.c#L598

Family history research, or genealogy, has traditionally been a hobby pursued mostly by middle-age adults and seniors. Formal college courses and advances in technology are now attracting teenagers and young adults to the pastime.
The Church of Jesus Christ of Latter-day Saints places a large emphasis on family history research and maintains FamilySearch.org, one of the largest genealogical Web sites in the world. Members of the Church, who believe they will be reunited in the afterlife with family members, consider it a religious obligation to trace their family history.
Avril Carranza, a sophomore from Mexico City, was exposed to genealogy early in life when her father took her to the Latter-day Saint family history center in their area.
Carranza is now studying family history in the School of History at Brigham Young University in Provo, Utah. When the major was introduced a few years ago, only a handful of students signed up. Now, she is one of over 100 young adults learning about genealogy at the school owned by The Church of Jesus Christ of Latter-day Saints. The university has created an online family history resource to make researching a little easier.
"Finding the right dates and actual documents from my ancestors' time is very fulfilling," Carranza says. She hopes to take her knowledge and passion for family history back to her home in Mexico after she graduates.
Brandi Hales, another young student, says by doing family history she is better able to understand her family and herself.
"It's like being a detective for your family," said Gerald Haslam, BYU family history coordinator. "After finding what you are looking for, you can share it with your living relatives. It really brings people together."
In addition to creating family bonds, Haslam says, family history builds a sense of security and teaches life lessons about discovering one's heritage.
Haslam says the program has attracted students from Iceland, Brazil, Denmark and other countries.
BYU is not the only school that offers genealogy courses to people of all ages. According to Web site www.my-history.co.uk, there are over 50 college and university courses available in the United Kingdom alone.
Recent college graduate of BYU Cara Whiting, originally from Connecticut, has taken her interest in family history to the National Archives in Washington, D.C., where she helps visitors with online research. Whiting has been fascinated with family research from a young age.
"I was the only child in my family that could place which cousin went with which aunt and uncle," she said.
Whiting believes family history has become more appealing to young people because of the technology that is now available.
"The way things are becoming more available and easy to access makes it easier to do," Whiting said. "It doesn't need to be an all-day commitment like it used to be."
Paul Nauta, manager of public affairs for FamilySearch, says family history work is a fun diversion from other activities young people are involved with. With new advances in technology, Nauta says it is more appealing than ever for them to get involved in family history.
"Young people are Internet savvy," Nauta said. "They are early adaptors to new programs online, and they can help those around them."
Calvin Coy, an 18-year-old from Sydney, Australia, juggles a busy lifestyle and still manages to squeeze in time to learn about his forebears. In his spare time he is able to get on the family computer to check the scores of his favorite sports team, send an e-mail or two and still have time to do some family history research.
Coy's interest in genealogy, and specifically in Scottish history and the tribal interactions between ancient European cultures, began over five years ago. Reading books and watching movies about the time period inspired Coy to learn more and eventually get interested in family history research.
"It was not until later that I learned of my Scottish heritage," Coy said. "I thought it was such a coincidence that something I was so interested in really was a part of me."
Michael Otterson, director of media relations for The Church of Jesus Christ of Latter-day Saints, encouraged students at Brigham Young University-Idaho in 2006 to join others who are engaging in family history research.
"Thousands of people have awoken to the realities of how our electronic age can transform our knowledge of our forebears and help us discover what was previously almost impossible to find," he said.
