Nobody in the UK gets denied healthcare if they want to pay for it. You can always go private, at which point it's the same as in the US. And as far as I understand it, healthcare prices in the US are so incredibly inflated that even though you might be paying for public healthcare that you then don't use on that particular occasion, you'll still have spent less money in total paying taxes and going private in the UK than you would do just getting private service in the US.

Shouldn't the size heuristics be in kernel space? Why should cp be analysing the RAM on the system? Take a look at the obscene hacky amount of heuristics userspace ends up with here, for example: http://insights.oetiker.ch/linux/fadvise/

IMHO, POSIX_FADV_SEQUENTIAL should be sufficient, but it doesn't seem to do anything useful (wrt. the page cache). I'm using POSIX_FADV_DONTNEED continuously on just-read pieces of file for an md5sum-type program (moderate CPU on a one-off sequential read), and this seems to work, but I'll also need to do the Oetiker mincore hack as referenced above in order to avoid evicting files out of the page cache if they were in there before.

This is a massive hack though; why shouldn't POSIX_FADV_SEQUENTIAL suffice? IMHO the kernel should do the following heuristic on POSIX_FADV_SEQUENTIAL: for large files don't cause cache misses to populate the cache. And cp could then do a single posix_fadvise and be done with it.

How do I get my editor to do that for me? Or am I supposed to hold down the space bar every time I want to line things up like that?

Also, how wide does my screen have to be? I like the 80 character standard. If the tabs have variable width, then what happens when I view someone's code with a tab width of 8 when he wrote it with 4? Everything wraps horribly? No thanks.

Just a thought. Here in Europe I drive a TDi and get 40-60 mpg depending on how hard I drive it.

However, I took a while getting the hang of it. The turbo only kicks in at about 2500 rpm, and only after a delay. If I want real acceleration this involves being in the right gear and getting the engine revved up in advance.

How much more difficult/impossible would this be in an automatic? A kick down won't work as well as there will still be a turbo lag.

In Europe this is easy: everyone drives stick.

Ubuntu LTS Experiences X.org Memory Leak 320

MonsterTrimble writes "Ubuntu 10.04 LTS Beta 2 is experiencing a major memory leak due to patches for X.org. 'An X.Org Server update that was pushed into the Lucid repository last week has resulted in the system being slower and slower as it is left on, until it reaches a point where the system is no longer usable. ... In order to make the Ubuntu 10.04 LTS deadline, the developers are looking at just reverting three of the patches, which brings the GLX version back to 1.2. Ubuntu developers are now desperate for people willing to test out this updated X.Org Server package so they can determine by this Friday whether to ship it with Ubuntu 10.04 LTS or doing an early SRU (Stable Release Update). Right now this X.Org Server that's being tested is living in the ubuntu-x-swat PPA.'"
