On the third day of the 2007 Taipei IT Month in Taiwan yesterday, notebook computers and desktop computers built with AMD’s Phenom processor and Intel Penryn processor openly battled for the consumer-market after each company launched their quad core processors.

Intel with partners like Acer, Genuine, ASUS, and Lenovo promoted their desktops with Core 2 Quad and notebooks with Centrino Duo, even though Intel didn’t plan to exhibit in IT Month. Intel’s Taiwan division is holding two road shows for DIY experts. One was on December 1 while the second will be on December 8.

AMD, on the other hand, put on a showcase for IT Month with a “Bee Movie“ booth-style exhibit at halls 1 and 3 of the Taipei World Trade Center. AMD’s subsidiary company ATI showcased HDMI and Full HD with a demonstration of a new graphic card named “Radeon HD2000”.

As the two rivals postured over factors like performance and high-definition, Wikinews reporter Rico Shen interviewed some of their partners. BenQ and Micro-Star International both said: “No matter whether the consumer chooses a computer with AMD or Intel, the consumer should consider it based on functionality and practically before purchasing. For example, some low-price notebook computers (EeePC, OLPC) were launched before the show because notebook computer manufacturers had considered and evaluated what a consumer really want. Sincerely, I recommend a consumer not be fooled by a its price but to consider its functionality first!”

Sales of existing homes in the U.S. fell 9.6% in February, the National Association of Realtors (NAR) said today, in a sign that the U.S. housing market is still depressed. The figure was worse than the 3.9% decline anticipated by the economists surveyed by Dow Jones Newswires and questions whether the U.S. housing market is beginning to recover or will continue to fall.

A combination of foreclosures and short sales, where the mortgage holder sells the house for less than owed on the mortgage, accounted for almost 40% of the sales.

Millions of foreclosures have forced down home prices and the number of foreclosures are predicted to rise this year. The inventory of existing homes listed for sale rose 3.5% at the end of February, a 8.6-month supply at the current sales rate. As more homes are listed in the spring, the inventory of houses for sale will probably increase. A five or six month inventory is usually considered a healthy balance between supply and demand.

According to Moody’s Analytics, another 3.6 million bank-owned homes and possible foreclosures will be added to the inventory by 2013, adding to the 6.7 million home foreclosures since 2006. Thus housing inventories will probably continue to remain high, delaying the point when prices stabilize. The median sales price in February fell 5.2%, down to a price level not seen since April 2002.

“We have an uneven, choppy recovery,” said NAR’s chief economist Lawrence Yun. “Hopefully it is a recovery that is taking place.”

Companies in the United States are shedding more jobs, pushing the country’s unemployment rate to a 26-year high of 9.8%.

The US Labor Department said on Friday that employers cut 263,000 jobs in September, with companies in the service industries — including banks, restaurants and retailers — hit especially hard. This is the 21st consecutive month of job losses in the country.

The United States has now lost 7.2 million jobs since the recession officially began in December 2007. The new data has sparked fears that unemployment could threaten an economic recovery. Top US officials have warned that any recovery would be slow and uneven, and some have predicted the unemployment rate will top 10% before the situation improves.

“Continued household deleveraging and rising unemployment may weigh more on consumption than forecast, and accelerating corporate and commercial property defaults could slow the improvement in financial conditions,” read a report by the International Monetary Fund’s World Economic Outlook, predicting that unemployment will average 10.1% by next year and not go back down to five percent until 2014.

Mark Zandi, chief economist at Moody’s Economy.com, said that “it’s a very fragile and tentative recovery. Policy makers need to do more.”

“The number came in weaker than expected. We saw a lot of artificial involvement by the government to prop up the markets, and now that that is starting to end, the private sector isn’t yet showing signs of life,” said Kevin Caron, a market strategist for Stifel, Nicolaus & Co.

Also on Thursday, the US Commerce Department said factory orders fell for the first time in five months, dropping eight-tenths of a percent in August. Orders for durable goods — items intended to last several years (including everything from appliances to airliners) — fell 2.6%, the largest drop since January of this year.

The US government has been spending billions of dollars — part of a $787 billion stimulus package — to help spark economic growth. There have been some signs the economy is improving.

The Commerce Department said on Thursday that spending on home construction jumped in August for its biggest increase in 16 years. A real estate trade group, the National Association of Realtors, said pending sales of previously owned homes rose more than 12 percent in August, compared to August 2008.

A separate Commerce Department report said that consumer spending, which accounts for more than two-thirds of US economic activity, rose at its fastest pace in nearly eight years, jumping 1.3 percent in August.

Other reports have provided cause for concern. A banking industry trade group said Thursday the number of US consumers making late payments, or failing to make payments, on loans and credit cards is on the rise. A survey by a business group, the Institute for Supply Management, Thursday showed US manufacturing grew in September, but at a slower pace than in August when manufacturing increased for the first time in a year and a half.

Stock markets reacted negatively to the reports. The Dow Jones Industrial Average fell 41 points in early trading, reaching a level of 9467. This follows a drop of 203 points on Thursday, its largest loss in a single day since July. The London FTSE index fell 55 points, or 1.1%, to reach 4993 points by 15.00 local time.

Stardust is a NASA space capsule that collected samples from comet 81P/Wild (also known as “Wild 2) in deep space and landed back on Earth on January 15, 2006. It was decided that a collaborative online review process would be used to “discover” the microscopically small samples the capsule collected. The project is called Stardust@home. Unlike distributed computing projects like SETI@home, Stardust@home relies entirely on human intelligence.

Andrew Westphal is the director of Stardust@home. Wikinews interviewed him for May’s Interview of the Month (IOTM) on May 18, 2006. As always, the interview was conducted on IRC, with multiple people asking questions.

Some may not know exactly what Stardust or Stardust@home is. Can you explain more about it for us?

Stardust is a NASA Discovery mission that was launched in 1999. It is really two missions in one. The primary science goal of the mission was to collect a sample from a known primitive solar-system body, a comet called Wild 2 (pronounced “Vilt-two” — the discoverer was German, I believe). This is the first [US]] “sample return” mission since Apollo, and the first ever from beyond the moon. This gives a little context. By “sample return” of course I mean a mission that brings back extraterrestrial material. I should have said above that this is the first “solid” sample return mission — Genesis brought back a sample from the Sun almost two years ago, but Stardust is also bringing back the first solid samples from the local interstellar medium — basically this is a sample of the Galaxy. This is absolutely unprecedented, and we’re obviously incredibly excited. I should mention parenthetically that there is a fantastic launch video — taken from the POV of the rocket on the JPL Stardust website — highly recommended — best I’ve ever seen — all the way from the launch pad, too. Basically interplanetary trajectory. Absolutely great.

Is the video available to the public?

Yes [see below]. OK, I digress. The first challenge that we have before can do any kind of analysis of these interstellar dust particles is simply to find them. This is a big challenge because they are very small (order of micron in size) and are somewhere (we don’t know where) on a HUGE collector— at least on the scale of the particle size — about a tenth of a square meter. So…

We’re right now using an automated microscope that we developed several years ago for nuclear astrophysics work to scan the collector in the Cosmic Dust Lab in Building 31 at Johnson Space Center. This is the ARES group that handles returned samples (Moon Rocks, Genesis chips, Meteorites, and Interplanetary Dust Particles collected by U2 in the stratosphere). The microscope collects stacks of digital images of the aerogel collectors in the array. These images are sent to us — we compress them and convert them into a format appropriate for Stardust@home.

Stardust@home is a highly distributed project using a “Virtual Microscope” that is written in html and javascript and runs on most browsers — no downloads are required. Using the Virtual Microscope volunteers can search over the collector for the tracks of the interstellar dust particles.

How many samples do you anticipate being found during the course of the project?

Great question. The short answer is that we don’t know. The long answer is a bit more complicated. Here’s what we know. The Galileo and Ulysses spacecraft carried dust detectors onboard that Eberhard Gruen and his colleagues used to first detect and them measure the flux of interstellar dust particles streaming into the solar system. (This is a kind of “wind” of interstellar dust, caused by the fact that our solar system is moving with respect to the local interstellar medium.) Markus Landgraf has estimated the number of interstellar dust particles that should have been captured by Stardust during two periods of the “cruise” phase of the interplanetary orbit in which the spacecraft was moving with this wind. He estimated that there should be around 45 particles, but this number is very uncertain — I wouldn’t be surprised if it is quite different from that. That was the long answer! One thing that I should say…is that like all research, the outcome of what we are doing is highly uncertain. There is a wonderful quote attributed to Einstein — “If we knew what we were doing, it wouldn’t be called “research”, would it?”

How big would the samples be?

We expect that the particles will be of order a micron in size. (A millionth of a meter.) When people are searching using the virtual microscope, they will be looking not for the particles, but for the tracks that the particles make, which are much larger — several microns in diameter. Just yesterday we switched over to a new site which has a demo of the VM (virtual microscope) I invite you to check it out. The tracks in the demo are from submicron carbonyl iron particles that were shot into aerogel using a particle accelerator modified to accelerate dust particles to very high speeds, to simulate the interstellar dust impacts that we’re looking for.

And that’s on the main Stardust@home website [see below]?

Yes.

How long will the project take to complete?

Partly the answer depends on what you mean by “the project”. The search will take several months. The bottleneck, we expect (but don’t really know yet) is in the scanning — we can only scan about one tile per day and there are 130 tiles in the collector…. These particles will be quite diverse, so we’re hoping that we’ll continue to have lots of volunteers collaborating with us on this after the initial discoveries. It may be that the 50th particle that we find will be the real Rosetta stone that turns out to be critical to our understanding of interstellar dust. So we really want to find them all! Enlarging the idea of the project a little, beyond the search, though is to actually analyze these particles. That’s the whole point, obviously!

And this is the huge advantage with this kind of a mission — a “sample return” mission.

Most missions rather do things quite differently… you have to build an instrument to make a measurement and that instrument design gets locked in several years before launch practically guaranteeing that it will be obsolete by the time you launch. Here exactly the opposite is true. Several of the instruments that are now being used to analyze the cometary dust did not exist when the mission was launched. Further, some instruments (e.g., synchrotrons) are the size of shopping malls — you don’t have a hope of flying these in space. So we can and will study these samples for many years. AND we have to preserve some of these dust particles for our grandchildren to analyze with their hyper-quark-gluon plasma microscopes (or whatever)!

When do you anticipate the project to start?

We’re really frustrated with the delays that we’ve been having. Some of it has to do with learning how to deal with the aerogel collectors, which are rougher and more fractured than we expected. The good news is that they are pretty clean — there is very little of the dust that you see on our training images — these were deliberately left out in the lab to collect dust so that we could give people experience with the worst case we could think of. In learning how to do the scanning of the actual flight aerogel, we uncovered a couple of bugs in our scanning software — which forced us to go back and rescan. Part of the other reason for the delay was that we had to learn how to handle the collector — it would cost $200M to replace it if something happened to it, so we had to develop procedures to deal with it, and add several new safety features to the Cosmic Dust Lab. This all took time. Finally, we’re distracted because we also have many responsibilities for the cometary analysis, which has a deadline of August 15 for finishing analysis. The IS project has no such deadline, so at times we had to delay the IS (interstellar, sorry) in order to focus on the cometary work. We are very grateful to everyone for their patience on this — I mean that very sincerely.

And rest assured that we’re just as frustrated!

I know there will be a “test” that participants will have to take before they can examine the “real thing”. What will that test consist of?

The test will look very similar to the training images that you can look at now. But.. there will of course be no annotation to tell you where the tracks are!

Why did NASA decide to take the route of distributed computing? Will they do this again?

I wouldn’t say that NASA decided to do this — the idea for Stardust@home originated here at U. C. Berkeley. Part of the idea of course came…

If I understand correctly it isn’t distributed computing, but distributed eyeballing?

…from the SETI@home people who are just down the hall from us. But as Brian just pointed out. this is not really distributed computing like SETI@home the computers are just platforms for the VM and it is human eyes and brains who are doing the real work which makes it fun (IMHO).

That said… There have been quite a few people who have expressed interested in developing automated algorithms for searching. Just because WE don’t know how to write such an algorithm doesn’t mean nobody does. We’re delighted at this and are happy to help make it happen

Isn’t there a catch 22 that the data you’re going to collect would be a prerequisite to automating the process?

That was the conclusion that we came to early on — that we would need some sort of training set to be able to train an algorithm. Of course you have to train people too, but we’re hoping (we’ll see!) that people are more flexible in recognizing things that they’ve never seen before and pointing them out. Our experience is that people who have never seen a track in aerogel can learn to recognize them very quickly, even against a big background of cracks, dust and other sources of confusion… Coming back to the original question — although NASA didn’t originate the idea, they are very generously supporting this project. It wouldn’t have happened without NASA’s financial support (and of course access to the Stardust collector). Did that answer the question?

Will a project like this be done again?

I don’t know… There are only a few projects for which this approach makes sense… In fact, I frankly haven’t run across another at least in Space Science. But I am totally open to the idea of it. I am not in favor of just doing it as “make-work” — that is just artificially taking this approach when another approach would make more sense.

How did the idea come up to do this kind of project?

Really desperation. When we first thought about this we assumed that we would use some sort of automated image recognition technique. We asked some experts around here in CS and the conclusion was that the problem was somewhere between trivial and impossible, and we wouldn’t know until we had some real examples to work with. So we talked with Dan Wertheimer and Dave Anderson (literally down the hall from us) about the idea of a distributed project, and they were quite encouraging. Dave proposed the VM machinery, and Josh Von Korff, a physics grad student, implemented it. (Beautifully, I think. I take no credit!)

I got to meet one of the stardust directors in March during the Texas Aerospace Scholars program at JSC. She talked about searching for meteors in Antarctica, one that were unblemished by Earth conditions. Is that our best chance of finding new information on comets and asteroids? Or will more Stardust programs be our best solution?

That’s a really good question. Much will depend on what we learn during this official “Preliminary Examination” period for the cometary analysis. Aerogel capture is pretty darn good, but it’s not perfect and things are altered during capture in ways that we’re still understanding. I think that much also depends on what question you’re asking. For example, some of the most important science is done by measuring the relative abundances of isotopes in samples, and these are not affected (at least not much) by capture into aerogel.

Also, she talked about how some of the agencies that they gave samples to had lost or destroyed 2-3 samples while trying to analyze them. That one, in fact, had been statically charged, and stuck to the side of the microscope lens and they spent over an hour looking for it. Is that really our biggest danger? Giving out samples as a show of good faith, and not letting NASA example all samples collected?

These will be the first measurements, probably, that we’ll make on the interstellar dust There is always a risk of loss. Fortunately for the cometary samples there is quite a lot there, so it’s not a disaster. NASA has some analytical capabilities, particularly at JSC, but the vast majority of the analytical capability in the community is not at NASA but is at universities, government labs and other institutions all over the world. I should also point out that practically every analytical technique is destructive at some level. (There are a few exceptions, but not many.) The problem with meteorites is that except in a very few cases, we don’t know where they specifically came from. So having a sample that we know for sure is from the comet is golden!

I am currently working on my Bachelor’s in computer science, with a minor in astronomy. Do you see successes of programs like Stardust to open up more private space exploration positions for people such as myself. Even though I’m not in the typical “space” fields of education?

Can you elaborate on your question a little — I’m not sure that I understand…

Well, while at JSC I learned that they mostly want Engineers, and a few science grads, and I worry that my computer science degree with not be very valuable, as the NASA rep told me only 1% of the applicants for their work study program are CS majors. I’m just curious as to your thoughts on if CS majors will be more in demand now that projects like Stardust and the Mars missions have been great successes? Have you seen a trend towards more private businesses moving in that direction, especially with President Bush’s statement of Man on the Moon in 2015?

That’s a good question. I am personally not very optimistic about the direction that NASA is going. Despite recent successes, including but not limited to Stardust, science at NASA is being decimated.

I made a joke with some people at the TAS event that one day SpaceShipOne will be sent up to save stranded ISS astronauts. It makes me wonder what kind of private redundancy the US government is taking for future missions.

I guess one thing to be a little cautious about is that despite SpaceShipOne’s success, we haven’t had an orbital project that has been successful in that style of private enterprise It would be nice to see that happen. I know that there’s a lot of interest…!

Now I know the answer to this question… but a lot do not… When samples are found, How will they be analyzed? Who gets the credit for finding the samples?

The first person who identifies an interstellar dust particle will be acknowledged on the website (and probably will be much in demand for interviews from the media!), will have the privilege of naming the particle, and will be a co-author on any papers that WE (at UCB) publish on the analysis of the particle. Also, although we are precluded from paying for travel expenses, we will invite those who discover particles AND the top performers to our lab for a hands-on tour.

We have some fun things, including micromachines.

How many people/participants do you expect to have?

About 113,000 have preregistered on our website. Frankly, I don’t have a clue how many will actually volunteer and do a substantial amount of searching. We’ve never done this before, after all!

One last thing I want to say … well, two. First, we are going to special efforts not to do any searching ourselves before we go “live”. It would not be fair to all the volunteers for us to get a jumpstart on the search. All we are doing is looking at a few random views to make sure that the focus and illumination are good. (And we haven’t seen anything — no surprise at all!) Also, the attitude for this should be “Have Fun”. If you’re not having fun doing it, stop and do something else! A good maxim for life in general!

An Oklahoma police officer is on paid administrative leave, following an altercation with ambulance personnel while they were transporting a patient to the hospital. Trooper Daniel Martin, a member of the Oklahoma Highway Patrol (OHP), was caught on video by his police vehicle’s dashboard-camera in a physical struggle with paramedic Maurice White, Jr. after Martin pulled the ambulance over. Martin had previously passed the ambulance while en route to another call, but came back and pulled over the ambulance. The incident occurred on May 24, and footage from the police dash-cam was released following a tort claim filed by paramedic White.

It has also been suggested that the previous call had in-fact been to pick up his wife from a police station who was then present in the car during the incident between Martin and the ambulance.

Footage by the OHP released Friday shows the ambulance personnel repeatedly informing Trooper Martin that they have a patient in the back of the ambulance that they are in the midst of transporting to the hospital. Martin yells at the ambulance driver for making what he claims was an obscene gesture – the ambulance driver asserts he raised both hands signalling confusion at the police officer’s actions. Trooper Martin can be heard telling the ambulance driver “I’m going to give you a ticket for failure to yield, and when I go by you saying ‘What’s going on?’ you don’t need to give me no hand gestures now, I ain’t going to put up with that [expletive], do you understand me?”

The video from the police dash-cam is eight minutes long, and paramedic White can be seen twice being pushed up against his ambulance by Trooper Martin. In one instance, Martin shoves White up against the ambulance while gripping his neck tightly with his other hand. In a written statement, paramedic White described the hold placed on him by the Trooper, stating “he engaged my trachea in a claw-like grip digging his nail into my neck while partially shutting off my air supply.”

The sister of the patient in the ambulance, Clara Harper, was following the ambulance and witnessed the incident. Harper later viewed the footage from the police dash-cam, and she stated to Tulsa World paramedic White “never once became aggressive to that trooper.” She asserted that “He did nothing wrong.” After the ambulance was allowed to continue transporting the patient to the hospital, Harper got into the ambulance to be with her sister. “She was scared, and I was trying to calm her down and telling her everything was going to be all right,” said Harper.

Paramedic White was interviewed by KOKI-TV, and recounted his thoughts as the incident was taking place. He stated his main concern was for his ambulance patient: “It was surrealistic because I’ve never had such an experience. My biggest concern was for the patient. If there’s any nightmare from this, it’s because of what that mother, that patient, had to go through.” White’s attorney told KOKI-TV that if White deemed the arrest to be unlawful, he had the right to resist it. White is a paramedic for Creek Nation Emergency Medical Services in Oklahoma. He told FOX News he was surprised at the actions of the police trooper. “He’s taken an oath, just as I have, to protect and serve. I could not believe that this was happening,” said White.

The Oklahoma Department of Public Safety decided to release the police dash-cam video publicly after amateur video of the incident was posted to the video-sharing website YouTube. Captain Chris West, spokesman for the OHP, explained why the video was not released earlier. “We’ve been well aware of the fact that this incident has drawn enormous attention, but made the decision to protect the integrity of the investigation, any and all relevant evidence, as well as the rights of the department employees,” said West. Prior to the release of the dash-cam video, a relative of the patient had posted video of the incident to YouTube. The son of the ambulance patient can be seen in a video stating to the camera “Highway patrolman pulled over my mom’s ambulance because he’s mad we didn’t pull over, and he tried to arrest … the EMT from taking my mother to the hospital.”

Richard O’Carroll, the lawyer for paramedic White, said that Trooper Martin abused his authority as a police officer. “Everything on this needs to relate back to why are we here? One man is there protecting a patient and one man is there abusing his authority and throwing his weight around,” said O’Carroll. White’s attorney filed a tort claim on behalf of his client in order to get the video of the police vehicle’s dash-cam released. Trooper Martin’s lawyer says he did not realize a patient was in the ambulance at the time of the incident.

O’Carroll explained the decision of paramedic White not to use sirens while transporting his patient to the hospital: “There was a reason he wasn’t running sirens. There was a suggestion of chest pains and a heart condition and sirens aggravate these conditions by increasing the blood pressure.” However the attorney for Trooper Martin, Gary James, said that the ambulance was not exempt from regulations because it did not have its sirens on. “If they’re not running their sirens or lights, they don’t get afforded any emergency vehicle exemptions,” said James. The OHP chief is handling an internal review into the incident. As of June 1, Trooper Martin has been on paid administrative leave.

Wikibooks, an Internet project which seeks to create free content textbooks using wiki technology, has published its February 2005 statistics. The Cookbook project leads the statistics, both by number of contributors (94) and by total edits (668). Newcomer of the month is “Wikibooks Pokédex“, with 337 edits by mainly one user, followed by “Programming:Ada” (320 edits). Seventy contributors edited on “Wikiversity“, followed by sixty-eight users on the “Jokebook“. Wikiversity is a project of its own which aims to build a collaborative learning environment online.

Wikibooks was originally meant as a place for textbooks and manuals but has increasingly become a community creating books on all kinds of subjects, with the cookbook being the most prominent example. Intended as a collection of recipes from around the world, it hosts recipes from Hamburger to Sushi, ethnic cuisines from the Caribbean to the Mediterranean, and gives background information on ingredients, nutrition, and many cooking techniques.

Wikis are openly editable websites that are often used to create knowledge bases. Wikibooks is a project operated by the Wikimedia Foundation, a non-profit organization based in the United States which runs several free content wikis, including Wikipedia, a free encyclopedia, and Wikinews, a free news source. The statistics for Wikibooks are extracted using an SQL query on the latest Wikibooks database dump.

The Minnesota Department of Health (MDH) has said that bars do not become exempt from to Freedom to Breathe Act by holding ‘theatre nights.’ The act, which is designed to ban smoking in bars, excludes actors in theatrical performances. The MDH has, however, said that “theatre nights being held in bars do not fall within the theatrical production exemption of the Freedom to Breathe Act.”

The press release by the MDM said that “in reviewing the law, MDH has determined that it has the authority to address theater nights and take enforcement action if the activity is an attempt to allow smoking in violation of the act.” It continued by saying that “the Minnesota Commissioner of Health Dr. Sanne Magnan said MDH will work together with local health agencies to bring establishments into compliance if they violate the law.”

The theatre nights sometimes involve bars calling the visitors to the bars “cast” with the entrance becoming a “stage entrance:” or something similar. The Minnesota Commissioner of Health commented on these actions by saying that “The law was enacted to protect Minnesotans from the serious health effects of secondhand smoke,” and that “We [the MDH] expect all establishments to comply with the law. It is time for the curtain to fall on these theatrics so that employees, and all Minnesotans, are protected from secondhand smoke.”
