Every cell in your entire body (on average) gets replaced over a 7 year span. If you figure that you stopped growing around 18, and your body has been slowly replicating itself since then, it completed the first full replication at 25, the

Looking at it a different way, it’s entirely possible that those grants are the same ones that the companies would have applied for to roll out broadband to rural areas. In that sense, it doesn’t spend tax dollars in excess of what would h

I think it stalls more innovation than it encourages, and generally prevents new entry into a technology space, because the existing players have all the patents that a new player would need to get started. The fewer players you have in a

I can do 60s in bursts, and the bursts have lasted as long as 2 months before. I usually burn out as soon as we hit the finish line, and work 10-20 hour weeks for a while until all the comp-time is used up. But I can really do a fantastic

Most games have all the assets loaded onto every client, and they just synchronize over the server like a glorified IRC channel. People reverse-engineered WoW servers, and then ran their own WoW communities for a decade until Blizzard fina

In the Pascal that I remember, strings were always 256 bytes and the first byte tracked the length, meaning they were always safe, though might get truncated. The LongString just did allocations whenever it needed, and was also safe, as lon

Actually, thinking back, the primary reason I did that was that bash can’t dereference a variable by its name stored in another variable without an eval, and calling eval on each access of the variable was slow. By eval-ing the whole metho

Btw, one of the things I came up with in bash was an “object oriented” pattern (antipattern?) where a “constructor” function would declare variables for “attributes” and functions for “methods”, like for example declaring an object named Ve

You forgot my favorite one! Xlib is written so badly that there is no graceful way to deal with a connection error to the server - the library gives you one callback to clean up and then it forcibly aborts the process. I looked into why,
