Comment: Re:Linus Torvalds and regression? (Score 1) 186

by fuzzix (#35917476) Attached to: Linux Kernel Suffering Power Management Regression?

I run my recently upgraded desktop (Core i5-2500K) through a power meter and it is very easy to notice - Ubuntu 10.10 (kernel 2.6.35) idles at about 30W, while 11.04 (2.6.38) goes up to 35W. That's about 20% more.

I believe 2.6.36 introduced a problem with DRI on intel and some other video chipsets which led to a shitload of kworker wake ups. One of my laptops running Arch benefitted from a kernel parameters suggestion over here but by that stage I had a menu.lst as long as your arm full of attempts at a functional system (e.g. kernel ... nohz=off highres=off pcie_ports=compat...) each with small, incremental improvements.

You can't catch every regression without owning all hardware and infinite time :)

a whole os, distro and the highlights include enabling http pipelining and including a couple of browser add-ons, switching default search engine
Really ? really ?
That's the problem that needs solving, thru a new disto

Yep, that's right, a whole new distro... to enable something that not everybody thinks is a great idea... I mean, if you want to make 200 http connections per web page have at it, but do it on some other web, not the one that myself and others enjoy traffic from.

Xen 4.1 Hypervisor Released 105

Posted by Soulskill
from the onward-and-upward dept.
LarsKurth writes "The Xen.org open source community just released a new version of the Xen Hypervisor, Xen 4.1. Feature highlights include a new prototype scheduler for latency-sensitive workloads, better support for very large systems (>255 CPUs, 1GB/2MB super page sizes), new security features, and many others. During the development cycle of Xen 4.1, the Xen community worked closely with upstream Linux projects to ensure that Xen dom0 support and Xen guest support are available from unmodified Linux distributions. The release announcement contains a full list of changes."

Does Typing Speed Really Matter For Programmers? 545

Posted by timothy
from the backspace-speed-is-key dept.
theodp writes "I can't take slow typists seriously as programmers,' wrote Coding Horror's Jeff Atwood last fall. 'When was the last time you saw a hunt-and-peck pianist?' Atwood's rant prompted John Cook to investigate just how important it is to be able to type quickly. 'Learning to type well is a good investment for those who are physically able to do so,' concludes Cook, 'but it's not that important. Once you reach moderate proficiency, improving your speed will not improve your productivity much. If a novelist writing 1000 words per day were able to type infinitely fast, he or she could save maybe an hour per day.' At 150 WPM, notes Cook, the world's fastest typist was still only 10x faster than Stephen Hawking."

The Case For Lousy Passwords 343

Posted by CmdrTaco
from the love-for-the-lousy dept.
itwbennett writes "Since the Gawker and McDonald's hack attacks, the web has been overrun with admonishments against using weak passwords. But weak passwords have their place too, says blogger Peter Smith. Like, for example, on Gawker, where he really doesn't care if it gets cracked. 'Life is too short to be worrying about 24 character passwords for trivial sites,' says Smith. And, to put things in perspective, your good passwords are pretty weak too. In a 2007 Coding Horror article, Jeff Atwood points out that the password "Fgpyyih804423" was cracked in 160 seconds by the Ophcrack cracker."

cylonlover writes "The Jack PC from Chip PC Technologies offers a neat and novel thin-client desktop computing solution where the computer doesn't just plug into the wall, it is the plug in the wall. Running on power provided by the ethernet cable that also connects it to the data center server, the computer-in-a-wall-socket supports wireless connectivity, has dual display capabilities and runs on the RISC processor architecture."

W3C Says IE9 Is Currently the Most HTML5 Compatible Browser 382

Posted by Soulskill
from the complain-about-the-tests-here dept.
GIL_Dude writes "The W3C posted results for their latest HTML5 compatibility tests and have found that, so far, IE 9 has the best overall results. 'The tests cover seven aspects of the spec: "attributes," "audio," "video," "canvas," "getElementsByClassName," "foreigncontent," and "xhtml5." The tests do not yet cover web workers, the file API, local storage, or other aspects of the spec. Not do they cover CSS or other standards that have nothing to do with HTML5 but are somehow lumped under HTML5 by the likes of Apple, Google, and Microsoft.'"

Taco Bell Programming 394

Posted by timothy
from the how-dare-you-insult-the-code-monkeys dept.
theodp writes "Think outside the box? Nah, think outside the bun. Ted Dziuba argues there's a programming lesson to be learned from observing how Taco Bell manages to pull down $1.9 billion by mixing-and-matching roughly eight ingredients: 'The more I write code and design systems, the more I understand that many times, you can achieve the desired functionality simply with clever reconfigurations of the basic Unix tool set. After all, functionality is an asset, but code is a liability. This is the opposite of a trend of nonsense called DevOps, where system administrators start writing unit tests and other things to help the developers warm up to them — Taco Bell Programming is about developers knowing enough about Ops (and Unix in general) so that they don't overthink things, and arrive at simple, scalable solutions.'"

Erm... yes, that's great and all. Except Hatsune Miku has been around since 2007, and versons of the the Vocaloid software that powers "her" has been around a good bit longer (since 2004 or so, I think). I'm pretty sure I heard reference to special-effects-heavy concerts more than a year ago.

Precisely. Japan's latest rock star is a discovery of the Whitman Campaign. Jerry Brown knows what I'm talkin' 'bout.

UK To Track All Browsing, Email, and Phone Calls 286

Posted by samzenpus
from the that-about-covers-it dept.
Sara Chan writes "The UK government plans to introduce legislation that will allow the police to track every phone call, email, text message and website visit made by the public. The information will include who is contacting whom, when and where and which websites are visited, but not the content of the conversations or messages. Every communications provider will be required to store the information for at least a year."
