A scheduler is the piece of software that brings you the illusion of multi-tasking. Because a single processor (with a single core) can only run one process at the same time, the operating system switches the process currently running. And it does this very fast (IIRC up to 1000 times a second in the case of linux).
The scheduler decides which process runs when and has to make sure that no process has to wait in the queue forever without getting his share of CPU time (this is what is called "starving").
Since the scheduler is a program by itself, it has a specific runtime characteristic, usually dependent of the number of programs waiting for their CPU share. The special property of the current scheduler in linux is that its runtime is in fact independent of this number. That's expressed in CS by O(1).
Too many of yesterday's assumptions in this article. It's about how the user should conform to what the program wants to do or is expecting. The program doesn't like an extra line space between paragraphs, so the user should inconvenience themselves by using styles and formatting instead.
No, the user should put a minimum of effort into learning how to use his tools efficiently. You know, style definitions aren't there to inconvenience users but actually to help them. That using styles makes converting documents easier is just a positive side effect but not the point of this feature.
If people know that and still prefer to take the "easy" route - that's fine with me, as long as they don't expect me to help them with the mess they have chosen.
Users are going to do what they do regardless. So I guess the answer is to write much better import/export filters for when files are going to be used in more than one program.
Filters can only guess which incidentally equally (or unequally) formatted parts of a text belong together. They will never beat a user who thinks a second about the structure of their document before starting to write it.
It's no good going on about typography either. Most people don't know what that is. But they know a friendly program that produces nice-looking results when they use it. And that is all they want.
No, they also want to be able to quickly change formatting of similar items (headings and such). This is impossible if the format the "easy" way.
Embedding active hyperlinks in documents could be a reason.
I don't know what an "active" hyperlink is, but my LaTeX documents always contain internal and external links. This very easy with the package hyperref. Regular \ref macros are automatically made clickable internal links in the PDF and the \url macro creates external links.
This is one of the things that seems really really hard for novice users : distinguising between email and browsing (many consider email as something not internet related),
What I find even more astonishing is, when people don't know that they don't have to read their mail via webinterface. It all boils down to the difference between the internet and the web. They just don't get the idea of different services through the same "channel".
and understanding that the browser is not the internet, as much as MS word is not your text document.
Tireless promoter of Mutt and Vim, and a really nice guy even after all these years of abuse from the n00bs.
Nice guy? Not in public. And some time ago he has shut down his site about his mutt configuration because he wants to enforce the work on bark, a new mailclient to come.
Anyone know which discs are needed for what installation you might want?
For a normal installation you only need to get the first two or three discs. If you have a fairly fast internet connection, you can even go with the
netinst image.
This installs a base system, reboots, and then you can get every package you want from a local mirror.
Being more of a physicist than software guru:-), I figured if my router told me it would only accept the wireless MAC addresses I told it to, nobody could get on my net without my knowledge. I sure hope this is true...
Not really. It is possible to fake MAC addresses.
Meanwhile I don't want to bother w/ WEP because that sounds like work (heh), so- can an outsider still tap into the data flow even if he can't connect?
Yes. If you put your wifi card into monitor mode you can see all the traffic your card can "grab out of the air" without being connected to an AP.
This should make it possible to find out MAC addresses which are accepted by the router.
To my knowledge, the best way to protect your traffic is to use encryption on higher level protocols, such as ssh, https etc or to tunnel everything through a VPN. Though I don't know what to do to prevent MAC spoofing.
Only on slashdot could the primary discussion on a topic end up discussing the terminology itself rather than the issue at hand:)
Obviously, you haven't been in usenet for a while.

Isn't the DDoS tag a little bit redundant for a submission which appears in Slashdot?
It's german.
You use SSH from public terminals?
Yes, as often as I would use my personal apps via some webinterface on public terminals. Of course, you could translate that to 'No'.
Imagine public terminals everywhere, allowing access into "the system", where you can reach all your data and applications.
Thanks, I already have ssh.
Sorry, of course you are right.

> IT STILL SHOWS UP! Really? I tried google.de and google.com/intl/en, but none of them showed any sponsored links at all.
In other news, The Register shows how stupid google's adword system is abused.
Dammit. Never leave a slashdot page to write en email and then come back for commenting it without a refresh.
mutt, slrn, w3m (for textdumps of html mails). HTH J.

"Where did you save your document?" -"In Word!"
I've never had a virus, worm, trojan, adware, or spyware, and I don't give a shit about Joe User.
Guess what OS I'm useing.
Mac OS X?
Nice try.
yeah!
(dammit, that friggin eleven fscks the whole joke up)
