And that's why the LSB will ultimately fail. It makes the developers lives a lot harder for very little gain. Most folks running commercial software on Linux will be using RedHat, so it makes sense to primarily target RedHat, and the rest of the distributions mostly follow RedHat's lead (for obvious reasons) so there generally isn't a problem.
I disagree. Right now if software people want to release binary software, they have to release packages for many different distros at once because they are _not_ all compatible at the lowest level (the c library, and other low level libraries that practically everything links with). With the LSB they should be able to release just one package and save a lot of work.
As for all the extra dependencies you mentioned, those could potentially cause a few problems, but I think it will be significantly less than are caused by differences in the really low level stuff.
I could be wrong though. I have never released binary packages for multiple systems.
In other words there really isn't a good way to know that your binary application is LSB compliant.
The slashdot blurb has a link to version 1.0.1 of the LSB test suite.
And if that isn't bad enough, the LSB isn't a particularly exciting platform to port to. Most of the cool new Linux features are not included. Basically the LSB is Linux with all of the joy sucked out. No wonder commercial vendors simply test against RedHat and call it good. It simply doesn't make sense to do anything else.
The LSB specifies a BARE MINIMUM. The "cool features" can be added by any LSB complaint Linux vendor very easily. Just because the LSB says that these features MUST exist, doesn't mean that ONLY these features must exist.
I was browsing rpmfind.net a few days ago, and I found a bunch of packages in Mandrake Cooker which were modified for LSB compatibility. That's probably a good sign.
Each software package you download comes in one big file, but instead of extracting the thing all over your file system, you just stick it somewhere in a packages hierarchy, like so:
etc., and write some software which will automagically go inside these packages and read any files from there. Then installing/uninstalling software is as simple as adding/removing one file.
Other than some possible efficiency problems, is there any other issues with such a scheme?
Rough rule of thumb is that the sun output about 1kW/sq. meter. Based on that, you can figure out how big an array you'd need, with a given efficiency.
For example, a 4x8 meter array, with 15% cells, outputs about 4*8*0.15*1 = 1.2kW power.
Now, figure out how much power your cooler needs, and design from there.
The WTC building is designed with columns on the whole outside of the tower, and more columns around a "central core" (Kind of like a big, square, O). Then there are beams linking the outside columns to the inside ones. These beams hold the building together. They also hold up each floor.
When the plane collided, it weakened some of the columns, but the building did not yet collapse (by design). While the fire burned, it weakened the beams, which then cracked under the pressure of the floor. When this happened, there was nothing holding the outside columns to the inside columns, which caused the building to collapse.
"Luckily", the building fell straight down (by design), and not sideways, which would have caused more damage.
In conclusion, it is the fire that caused the collapse, and the building did not "disintegrate", but did collapse in a designed pattern.

At full sunlight intensity, the sun outputs about 1000W/square meter. Most common solar cells right now are about 15% efficiency (although you can get them commercially at atleast 22%), where you'd get about 150W/sq. meter at full sunlight. That's not too bad, considering 8 sq. meters of these solar cells can propell a solar car at well over 100km/h.
Of course you'd have to augment the solar cells with batteries. Have the cells power the the devices and charge the batteries during the day, and use plain batteries during the night.
It's already been done to an extent. SolarHost offers web hosting powered by solar power. They are the people providing hosting for The Formula Sun website. (Formula Sun, incidentally, is a group of races across the USA in various solar powered vehicles. Shameless Plug)
At my school, they've been doing this for a while now with multiple choice exams. They figure out, statistically, who is likely to have cheated, and the correlate with seating positions and stuff, so it's fairly effective.
I'm using Rogers@home, and in my area, it is significantly faster than DSL. I don't suffer from the over-subscription problem. I can get 200kB/s down easy...sometimes more. And it's fairly steady morning/evening/night/etc. Up time is good too. But they cap up at about 30-40kB/s.
was take both. The University I'm at (University of Western Ontario) lets me take Computer Engineering and Computer Science concurrently, and graduate with both degrees in only 5 years.
And a nice benefit of going into engineering is that you can then become a fully licensed Professional Engineer (which actually MEANS something up here in Canada).
A major difference between the engineering vs. the science program, is that science tends to focus more on the theoretical knowledge, and engineering on the practical applications of the knowledge.
Basically, look into exactly what each program offers, and how that would fit into what you want to do.
A Fluke Hydra series wireless data logger should be able to take care of this. If you want something cheaper, take a look at PC/104 aquisition boards from Diamond Systems. You can link them up to a PC with a wireless modem.

No, this is the right list. It was even linked to in the article, if you bothered to check...
Yeah, here in London ON, our autumn was more green than our summer! :) (because of the dryness).
:)
We have about a centimetre of snow on the ground now though...
Some funky weather indeed
I'm in London, and my IP has changed only once so far (and since I had static settings, I didn't notice it until I booted into Windows one day :)).
But now Rogers is warning everyone to switch to dynamic settings, and that their connections will break when they switch (Nov 30th), so be careful.
Should we really be taking advice on building a web server from someone who's server crashes under /.s load?
What if we did something like this:
Each software package you download comes in one big file, but instead of extracting the thing all over your file system, you just stick it somewhere in a packages hierarchy, like so:
/packages/graphics/gimp.package
/packages/net/mail/pine.package
etc., and write some software which will automagically go inside these packages and read any files from there. Then installing/uninstalling software is as simple as adding/removing one file.

This kind of reminds me of Squant.

Isn't that exactly what Babylon 5 was about?
And there's also a Canadian version of TV Guide here.

Or what if they linked to a results page of a search engine listing sites with DeCSS? Is this now legal?
Mine isn't capped for total usage... and it's fast too!
