I always imagined that port allocation was a much more formal process more akin to an ISO or ECMA standardisation, but nope - Tatu sent an email asking for it and Joyce basically just replied with &amp;quot;sure thing, it&amp;#x27;s yours&amp;quot;. For something as critical as port allocation it&amp;#x27;s pretty interesting&amp;#x2F;funny how casual it was.</text></comment>

I couldn&amp;#x27;t compile the program so I was asking for help.&lt;p&gt;I thought I was going to wait for a long time, but was surprised when a response came a few minutes after. The response came from the author of the program itself, and he was very nice in how he answered my question. It was obvious that I was a noob and needed hand-holding. It made a lot of difference to me.&lt;p&gt;You have no idea how that positive response affected Tatu.&lt;p&gt;&lt;i&gt;Edit: Changed possible to positive in the last paragraph.&lt;/i&gt;</text></comment>
