Comment: What's changed in two and a half decades? (Score 1) 26

I haven't followed this race in a very long time though, I do remember GM's Sunraycer back in 1987. My question is: what has changed in the past twenty-six years? From a quick look on Wikipedia I see that the average speeds are higher but nothing like double what they were back when I was a kid. Is it safe to assume that the improvements made have been largely incremental? Are we talking about an ever so slightly more refined design every two years, better solar tech, better drag calculations? Please don't think I'm flaming. I all challenges like this one. I'm simply interested in what kind of progress has been made.

I think a fair chunk of the "/bin/cp /from/large.iso /to/large.iso" problem could be eliminated if cp (and dd) helped the kernel and dropped the page-cache on large copies via fadvise/madvise. Linux really defaults to the most optimistic assumption: that apps are good citizens and will dirty only as much RAM as they need. Thus the kernel will generally allow apps to dirty a fair amount of RAM, before it starts throttling them.

Why haven't basic system tools like cp had this functionality added to them? I can't imagine the required patches would be incredibly complex.

Speaking of kinematics, you might want to take a look at a EMC (Enhanced Machine Controller). EMC is a CNC package originating from NIST. EMC has an active community using and developing it. There are known bugs in the forward and inverse kinematics for PUMA style robots that could really uses the eye of a trained mathematician.

I'm sure there are are plenty of other areas that the EMC project could utilize your math skills. There are many, many users and developers of EMC that would appreciate your skills.

What is learned by simply booting up a VM and loading a game? In the story submission he specifically mentioned "all the fun workarounds" that he had to come up with get everything to work on a modern system. Don't you think doing a cleanroom reimplementing a subsystem like DirectDraw presents a great learning experience?

No, I wouldn't have done this if you had payed me; I have my own interests and passions. I'm not at all interested in graphics programming or for that matter video games, though, apparently someone is and I think it's great that he saw a problem and decided to attempt to find a solution for it.

This is what being a geek is all about. Bravo.

I would LOVE to start my own cable company that simply pushed analog and QAM TV without the need for converter boxes and was utterly lacking in all but absolutely require encryption. I think the public would love to use their own TV tuners again and be able to build their MythTV boxes/use their Tivos without having to clear it with some mystical gate keeper.

I live in the Pacific Northwest (NW US) where Comcast is the one and only cable provider (there are some outer-suburbs with FiOS but not tons). I recently started researching my cable situation and found that Comcast pushes all their Basic Digital channels (2-71 plus some), which is all I subscribe to via clear/unencrypted QAM[1]. It turns out that most if not all of Comcast's West Coast network is the same. This means it dead simple to hookup a HDHomeRun from Silicon Dust to a MythTV box.
