Can anyone explain the difference between 'Priority Best Effort' (PBE) queueing and 'Best Effort' (BE) queueing?
If a node isn't saturated, are the BE packets delayed and if it is saturated will they just not arrive?

I suppose I could have tackled some long neglected household repair, or I could have just kicked back and overdosed on Christmas movies and bowl games like I usually do this time of year. But instead, after lounging around for a day or so, a light bulb went off over my head. An iPhone application! I was going to try my hand at developing an iPhone application."

Linux-hackers? Can they get in on the fun too? Just how hard is it for a coder experienced in Linux and C to write an iPhone application? Smallnetbuilder.com is running an article entitled, How To Write an iPhone App in 14 Days which describes one Linux hacker's iPhone application journey.
NewYorkCountryLawyer writes: "It appears that one of the 'last people sued' by the RIAA, in the flurry of lawsuits commenced just prior to its announcement that its litigation campaign was folding up its tents, was a Pittsburgh area college student named Jerome Williams, against whom a complaint was filed on December 15th in Atlantic Recording v. Williams. While he was unlucky to get caught in the RIAA's propellor blades at the tail end of the campaign, he was, unlike most victims of the RIAA's 5 1/2-year onslaught, able to find spirited legal counsel who are hopping mad about the RIAA's lawsuits, saying that 'Just because the record industry plaintiffs are mammoth corporations with massive financial resources does not justify them shirking their burden of proof under the law, particularly when their claims can have such dire repercussions on often powerless individuals.' His lawyers have taken the fight to the RIAA, filing a motion to dismiss the complaint for legal insufficiency. I guess you know who I'm rooting for."
Hugh Pickens writes: "Bell Curve author Charles Murray has a new book out arguing that too many kids are now heading to four-year colleges and wasting their time in pursuit of a bachelor's degree that is a meaningless credential and that only 20 percent of all college students have the brains and abilities to understand their assigned reading. Deborah Solomon has an interview with Murray in the NY Times in which Murray says that "there are very few unemployed first-rate electricians. I can get a good doctor in a minute and a half. Getting a really good electrician — that's hard. If you want jobs that are in high demand, go to any kind of skilled labor.""

They even opened up a few boutique retail outlets along the way. They had a funky vibe going with their black and white cow-spotted boxes, and the future seemed very bright indeed. That future never materialized, and Gateway was acquired by Acer last year for a comparatively modest $710 million. Now Gateway has completely
ended the business model that put them on the map: Direct Sales. Acer doesn't do direct sales, and brought their market vision to their new acquisition." Link to Original Source
MojoKid writes: "Part of GM's decision to move forward with their Chevy Volt electric car concept is a direct result of
Dr. Lyle Dennis' efforts. The primary function of Dennis'
GM-Volt.com site was to assemble
a list of potential customers interested in purchasing a Volt. Dennis hoped that if enough people expressed interest, GM would respond by committing to manufacture the car. Now that GM has committed to getting the electric car in production before the end of 2010, Dennis's next goal is "to try and compel GM to build enough cars for us," as Dennis claims that GM's "actual production numbers are projected to be modest at first."
This next step for Dennis was started by his publicly releasing the metrics from
his site's wait list, which had reached 33,000 people potentially interested in
purchasing a Chevy Volt. Dennis released this information yesterday in a blog
post on his site. As of when
this news post was written, that number had already gone up to 34,503
people." Link to Original Source
CWmike writes: "After the computer network at the Naval Weapons Station Earle was breached and crashed just a few weeks after the terrorist attacks of Sept. 11, 2001, investigators thought it might be part of a larger al-Qaeda plot against the United States. Was the break-in organized by a nation-state? A terrorist group? After throwing critical resources at the probe when the government was already investigating not only the 9/11 attacks but the anthrax killings, investigators didn't track the breach to al-Qaeda. They tracked it to an unemployed system administrator in the U.K. — Gary McKinnon, who has said he broke into U.S. military computers hoping to uncover evidence of UFO. He has been charged with hacking into 92 computer systems at the U.S. Army, the U.S. Air Force, the Department of Defense and NASA. "The concern was there," said Howard Schmidt, who began working at the White house as the vice chairman of the President's Critical Infrastructure Protection Board in 2002, in the midst of the McKinnon investigation. "When these things take place, you never know till the very end what their motivation is.... You don't know if it's a nation-state or a terrorist group. You have to work it as if this was the most important case you ever worked. There is a finite amount of resources. This pulled big resources that could have been used for other things.""
MojoKid writes: "According to the Electronic Frontier Foundation (EFF), a
dangerous legal precedent has just been set that can potentially unravel existing federal privacy protections for e-mail and Internet usage. The alert from the EFF is not just to sound a general warning, but it also takes the form of an Amicus curiae (friend of the court) brief, filed with the federal 9th U.S. Circuit Court of Appeals, asking for the court's legal finding to be overturned. The findings of this case
could become the foundation of a
legal precedent by which other similar cases can subsequently be based upon. If that were to be the case, then the unauthorized retrieving of e-mails from an e-mail server would not be considered a violation of the federal Wiretap Act, which
will then open the door for government-sponsored snooping." Link to Original Source
Roland Piquepaille writes: "A few months ago, I've written about the most powerful microscope in the world which was able to display images at an incredible high-resolution of just 0.05 nanometer (or 50 picometers). It seems that German scientists also have pushed electron microscopy to the picometer scale and broke the record for the highest-resolution images ever seen. The German team said they were able to 'microscopically measure atomic displacements precisely to a few picometers.' According to the scientists, it is possible to see atoms moving by only 10 picometers (or 0.01 nanometer). This could open new paths for research about physics of materials.

Roland Piquepaille writes: "Scramjets, or supersonic combustion ramjets, such as the X-51A aircraft being built by Pratt & Whitney and Boeing, should start to fly in 2009. And if everything goes according to plan, missiles flying at Mach 6 could be deployed by 2015. But designing such planes is not so easy. This is why Purdue University engineers have developed the only wind tunnel capable of running quietly at 'hypersonic' speeds. The Purdue engineers say that this 'quiet wind tunnel operation is critical for collecting data to show precisely how air flows over a vehicle's surface in flight' at hypersonic speeds. But read more for additional references and pictures of the Boeing/AFOSR Mach-6 Quiet Tunnel."
