Mod parent up.

Many of the benchmarks (such as the lame, Java and RAM bandwidth benchmarks) are CPU-bound, and will run the majority of time in userspace. As the kernel should only be invoked for timer ticks, interrupts, TLB misses, etc (which would probably account for less than 1% of the CPU time), and change to the kernel should have minimal impact on the benchmarks.

The parent's comment that power settings have been misconfigured sounds spot-on.

Submission + - A campaign to block Firefox users (whyfirefoxisblocked.com) 5

Submitted by rarwes on Friday August 17, 2007 @03:32AM

rarwes writes: A website is aiming at blocking Firefox users. This because a fraction of the Firefox users installed an Ad Blocker and thus stealing money from website owners that use ads. They recommend using IE, Opera or IE tab. From the site: Demographics have shown that not only are FireFox users a somewhat small percentage of the internet, they actually are even smaller in terms of online spending, therefore blocking FireFox seems to have only minimal financial drawbacks, whereas ending resource theft has tremendous financial rewards for honest, hard-working website owners and developers.

Submission + - Spam-bot intrusion caught! Now what?

Submitted by Anonymous Coward on Monday February 19, 2007 @07:49PM

An anonymous reader writes: I've recently detected and halted an intrusion on my home computer, taken some actions to prevent further intrusions, and located the software that was running a bot agent. Cursory examination showed that the bot software is intended for acting as an agent for spamming. Configuration files distinctly point at the user/host/domain of several bot-herders — damning evidence. To whom should I disclose this information for appropriate investigation, follow up, and countermeasures? Nothing would please me more than to see this botnet to be caught and dissassembled, I'm sure much of the internet-using community would support this. Thanks in advance for your suggestions.

Submission + - March is the Month of PHP bugs

PHP writes: "Stefan Esser is the founder of both the Hardened-PHP Project and the PHP Security Response Team (which he recently left). During an interview with SecurityFocus he announced the upcoming "Month of PHP bugs" initiative: "We will disclose different types of bugs, mainly buffer overflows or double free(/destruction) vulnerabilities, some only local, but some remotely trigger-able (for example, because they are in functions usually exposed to user input). Additionally there are some trivial bypass vulnerabilities in PHP's own protection features. [...] As a vulnerability reporter you feel kinda puzzled how people among the PHP Security Response Team can claim in public that they do not know about any security vulnerability in PHP, when you disclosed about 20 holes to them in the two weeks before. At this point you stop bothering whether anyone considers the disclosure of unreported vulnerabilities unethical. Additionally a few of the reported bugs have been known for years among the PHP developers and will most probably never be fixed. In total we have more than 31 bugs to disclose, and therefore there will be days when more than one vulnerability will be disclosed. The Month of PHP bugs will take place in March 2007.""

Submission + - Rollable E Ink Display Becomes Real Product

Submitted by on Sunday February 18, 2007 @05:58AM

An anonymous reader writes: Two years ago Philips unveiled a prototype of a functional electronic-document reader, called the Readius, which could unroll its display to a scale larger than the device itself. Unfortunately, that was only a prototype. According to Cnet, however, Polymer Vision, which spun out from Philips in 2006, has redesigned the Readius and turned it into a real product that it is going to be available by the end of this year. There are some notable differences between this Readius and the prototype version, in particular, the ability to display 16 shades of grey instead of just 4 and the connectivity options. What doesn't make sense though, is given the energy efficiency and easy-to-read high contrast functionality of E Ink, why other than Motorola with its Motofone, has no other cell phone manufacturer incorporated E Ink technology into its handsets?

Suppressed Report Shows Cancer Link to GM Potatoes 325

Posted by Zonk on Sunday February 18, 2007 @01:38AM from the politics-and-potatoes-and-science-mix-poorly dept.

Doc Ruby writes "After an 8-year-long court battle, Welsh activists have finally been allowed to released a Russian study showing an increased cancer risk linked to eating genetically modified potatoes. While the victory of the Welsh Greenpeace members in the courtroom would seem to vindicate the work of the Russian scientists that did the original research, there are still serious questions to be answered. The trials involved rats being fed several types of potatoes as feed. The rats who were fed GM potatoes suffered much more extensive damage to their organs than with any other type; just the same, serious questions remain about the validity of the findings. The Welsh group wants to use this information to stop the testing of GM crops in the UK, tests currently slated for the spring of this year."
