Visualizing System Latency 68

Posted by timothy
from the picture-says-1000-64-bit-words dept.
ChelleChelle writes "Latency has a direct impact on performance — thus, in order to identify performance issues it is absolutely essential to understand latency. With the introduction of DTrace it is now possible to measure latency at arbitrary points; the problem, however, is how to visually present this data in an effective manner. Toward this end, heat maps can be a powerful tool. When I/O latency is presented as a visual heat map, some intriguing and beautiful patterns can emerge. These patterns provide insight into how a system is actually performing and what kinds of latency end-user applications experience."

Sticky Rice Is the Key To Super Strong Mortar 194

Posted by timothy
from the what-can't-sticky-rice-do? dept.
lilbridge writes "For over 1,500 years the Chinese have been using sticky rice as an ingredient in mortar, which has resulted in super strong buildings, many of which are still standing after hundreds of years. Scientists have been studying the sticky rice and lime mortar to unlock the secrets of its strength, and have just determined the secret ingredient that makes the mortar more stable and stronger. The scientists have also concluded that this mixture is the most appropriate for restoration of ancient and historic buildings, which means it is probably also appropriate for new construction as well."

Huge Unidentified Organic Blob Floating Around Alaska 424 Screenshot-sm

Z80xxc! writes "The Anchorage Daily News reports that a 15 mile-long blob of unknown, 'gooey,' probably organic material is floating past communities on Alaska's North Slope. The US Coast Guard sent pollution experts to investigate, who determined that it was not an oil spill or other type of pollution, but were unable to determine what it is. A sample is currently being analyzed by experts in Anchorage, while the blob is following the current northwards."

> The reason that many of these laptops are listed as worth ~$3,000 is probably that some of them are 10+ years old (when laptops were really really expensive).

I am sure even the government ( especially the government ? ) does write-offs ( http://en.wikipedia.org/wiki/Write-off#Accounting ) over 3 to 4 years for a laptop.

Office 2007 Fails OOXML Test With 122,000 Errors 430

I Don't Believe in Imaginary Property writes "Groklaw is reporting that some people have decided to compare the OOXML schema to actual Microsoft Office 2007 documents. It won't surprise you to know that Office 2007 failed miserably. If you go by the strict OOXML schema, you get a 17 MiB file containing approximately 122,000 errors, and 'somewhat less' with the transitional OOXML schema. Most of the problems reportedly relate to the serialization/deserialization code. How many other fast-tracked ISO standards have no conforming implementations?"

Psychologist Beating Math Nerds in Race to Netflix Prize 205

Posted by Zonk
from the must-calculate-harder dept.
s1d writes "An almost-anonymous British psychologist named Gavin Potter has suddenly risen to the top of the Netflix prize charts. With his very first attempt, he got a score which took the BellKor team seven months to reach. Currently at a score of 8.07, he has only five teams ahead of him now in the race for the ultimate Netflix algorithm. 'Potter says his anonymity is mostly accidental. He started that way and didn't come out into the open until after Wired found him. "I guess I didn't think it was worth putting up a link until I had got somewhere," he says, adding that he'd been seriously posting under the name of his venture capital and consulting firm, Mathematical Capital, for two months before launching "Just a guy." When he started competing, he posted to his blog: "Decided to take the Netflix Prize seriously. Looks kind of fun. Not sure where I will get to as I am not an academic or a mathematician. However, being an unemployed psychologist I do have a bit of time."'"

Ford Claims Ownership Of Your Pictures 739

from the like-a-child-shouting-MINE dept.
Mike Rogers writes "In a move that can only be described as 'Copyright Insanity', Ford Motor Company now claims that they hold the rights to any image of a Ford vehicle, even if it's a picture you took of your own car. The Black Mustang Club wanted to put together a calendar featuring member's cars and print it through CafePress, but an attorney from Ford nixed the project, stating that the calendar pics and 'anything with one of (member's) cars in it infringes on Ford's trademarks which include the use of images of their vehicles.' Does Ford have the right to prevent you from printing images of a car you own?"

Apple's Leopard Will Exclude 800MHz G4 Processors 371

from the older-tech-gets-forked dept.
goombah99 writes "According to AppleInsider, Apple is about to announce that Leopard will not support 800 MHz G4 PowerPC processors. Previously developers had been told that it would require at least an 800 MHz G4. But AppleInsider alleges only 867 MHz G4s and higher will now be supported because of speed issues, and testers have been told that the new OS 'cannot be installed' on lesser machines. This cutoff in minimum requirements means that all those original iMac flat screens and Titanium PowerBooks are now forked to the Tiger (10.4) Update Path."

The Linux Identity Crisis 364

from the wants-to-be-called-linuxette-now dept.
Jayze Calrtini writes "From an article from ZDNet:"If you've been following the current rift in the Linux community between Linus Torvalds and his minions squaring off against Con Kolivas and the mainstream Linux fanatics, you probably know that it's getting quite heated. You also probably know that these two entirely different ideas could create three possible paths Linux can take for the future: stay geeky and appeal to the advanced tech guru in all of us; go mainstream and leave the advanced functionality and reliable kernel behind to compete with Microsoft and Apple; or face a "civil war" that could lead to total Linux annihilation."

Ballmer Says Google's Growth Is 'Insane' 420

Posted by Zonk
from the doubling-the-doubled-growth-rate dept.
eldavojohn writes "Steve Ballmer spoke to the Seattle PI this week, commenting that Google's pace of employee growth is 'insane,' and the company has few successful businesses outside of Internet search and advertising. He referred to Google's non-search efforts as 'cute.' Google's current number of employees is nearly doubling each year. 'I don't really know that anybody's proven that a random collection of people doing their own thing actually creates value.' Mr. Ballmer went on complain that, in general, competition for good programmers has become an issue. Even 'hedge funds' are looking for skilled coders, making the HR fight between the two companies that much more challenging."

RIAA Has to Disclose Attorneys Fees In Foster Case 193

from the it-feels-good-to-come-clean dept.
NewYorkCountryLawyer writes "The RIAA has been ordered to turn over its attorneys' billing records by March 26, 2007, in Capitol v. Foster in Oklahoma. The 4- page decision and order, issued in connection with the determination of the reasonableness of Ms. Foster's attorneys fees, requires the RIAA to produce the attorneys' time sheets, billing statements, billing records, and costs and expense records. The Court reviewed authorities holding that an opponent's attorneys fees are a relevant factor in determining the reasonableness of attorneys fees, quoting a United States Supreme Court case which held that 'a party cannot litigate tenaciously and then be heard to complain about the time necessarily spent by his opponent in response' (footnote 11 to City of Riverside v. Rivera)."

The reason that every major university maintains a department of mathematics is that it's cheaper than institutionalizing all those people.
