Domestic Car DVD with its low prices, features and all were accepted by the majority owners, to maintain very large market, the brand is countless. They all have one common feature is the failure rate is very high, usually with a one and a half or a few months there will be not its reading, dish out poor, poor performance of fault earthquake. Here is my fault machine repair some of these maintenance steps and experience for advanced users

1, not its reading. Its reading phenomenon is not accounted for 85% of the amount of maintenance. 45% of the damage for the spindle motor, 45% for the shaved head cable break (the naked eye is difficult to judge), 5% for the shaved head is damaged, the other 5%

1. The spirit of the principles of the easier to see the cleanliness of laser head, the first laser cleaning with alcohol cotton balls

2. Put a disc in, then power off, feeling his hand aside about whether the rotating disc with ease, a sense of whether the lag (of course this is usually a feeling of experience), if there is delay or resistance to change spindle motor

3. If the disc rotate freely, inertia is very good for root skinhead cable a try

4. After these three steps or not its reading, then, to try another skinhead

5. Measure drive power, check the drive power supply, insurance, substitution drive block

Second, poor access to disc. This phenomenon accounts for 10%.

1, cleaning roller into the dish

2, if there is no friction roller and the axis, then only transparent tape wrapped around the shaft three times to increase friction

3, is also a situation that CD in the CD into the CD port into DVD disc players is not the state, or the withdrawal of a CD-ROM disc into the disc motor can not continue to rotate. This phenomenon is the detection of infrared light-emitting tube into the disc aging, to be replaced to two. Are usually substituted with the remote IR control, but that is not sustainable

Third, poor shock performance. This phenomenon generally associated with its reading slowly, choose dishes. Cleaning laser head can be alleviated, if it is broken shock absorber rubber must of course changed

Fourth, there are no sound problems. Here to talk about is no sound in the car, but the table is another normal speaker wire bond strap, if continued long in this case is very easy to burn the boot block amplifier. Most domestic machines are dual-panel, so there were fewer amplifier block Weld

5, the other panel keys are damaged panel cable fault break and so intuitive that no more

MP3 player … … After a few years of development, penetration has been quite amazing, to hear two or three hundred dollars Office MP3 players can be seen as "a staff" to describe that enough. We often mouth hanging "cheap no good goods", why some are selling so cheap, some are selling so expensive? Some of the more avant-garde consumers would certainly say: "Some good quality, brand name, and of course the expensive!" A look that is no less consumers spend money on things that, huh, huh!

In fact, China’s consumer prices are generally more sensitive to price shopping first on foremost concern, followed by the brand and quality. The IT products is certainly no exception, they also require careful consideration, IT products like home appliances, buy a TV can be used for a decade or no problem, but a very short period out of IT products, a current mainstream PC be eliminated after two years is a normal thing.

The sooner the sooner the depreciation out of that, many consumers reluctant to spend too much money to buy IT products is a reason. "Buy enough of the line." And it is true enough, but really it? Two or three hundred dollars of the MP3 player is certainly cheap, and also in China the level of consumption, but in the end the two hundred dollars behind the "dragon" or "bug"?

But what does CME get from joining the Linux Foundation?

commentary

I’ve been pining lately for greater enterprise participation in open source, following the lead set by Red Hat CEO Jim Whitehurst, and so was excited to see the recent news that the Chicago Mercantile Exchange (CME) has joined the Linux Foundation. For CME, time is money, with a record 2.2 billion contracts in 2007 worth more than $1.2 quadrillion, all running on Linux (Red Hat Enterprise Linux, in this case).

In other words, CME wants to be both a producer and a consumer of open-source software, and specifically Linux in this case. CME has been a longstanding user of Linux, deriving considerable value from Red Hat Enterprise Linux since at least 2004. Now it’s time to start giving something back.

By joining the Linux Foundation, CME Group will be able to collaborate with key Linux developer and vendors. CME Group’s Vinod Kutty, associate director and head of distributed computing R&D, will become chair of the Linux Foundation’s End User Council. The Council is a group of the largest Linux end users who use the forum to collaborate and educate themselves on technical, legal and community efforts.

It’s been a few weeks since the RSA Conference 2008 and I’m now preparing for Interop. Nevertheless, I wanted to get in my two cents worth regarding Craig Mundie’s RSA keynote address on what Microsoft is calling “End to End Trust.”

In past years, Microsoft keynotes were full of product demonstrations and funny video montages. Its End to End Trust discussions demonstrate a new Microsoft focus–and the remaining problems associated with information security.

• 2. A new identity model. Identity is no longer about user name and password alone. In today’s computing environment, you also have to consider device type (i.e., am I communicating via my PC, cell phone, or PDA?), location, and the user’s work and personal profile. Yes, this complicates things but there is no getting around the fact that I use the same laptop to do my job during the day and then bid on vintage Gretsch guitars at night.

• 3. Industry participation. Microsoft readily admits that it can’t establish end-to-end trust on its own. Of course, Microsoft won’t be shy about suggesting technologies for connectivity and standardization, but it really does need help here. It’s time that the security industry stop its outright mistrust of Microsoft and extend an olive branch.

In my view, Mundie’s keynote was effective in that it really got the industry’s attention. Many security professionals and vendors recognize the need for this End to End Trust model while organizations like the Computer Security Institute (CSI), the National Institute of Standards (NIST), and the Trusted Computing Group (TCG) are already working on similar efforts.

• 1. A chain of trust. As the old security saying goes, “the security chain is only as strong as its weakest link.” Microsoft has done a good job making Windows more secure with each iteration but it really doesn’t matter if the bad guys compromise your data by hacking in at the application layer. Microsoft is suggesting a model where the entire technology stack must adhere to a trust relationship (i.e., each piece is authenticated and validated and all changes must be approved) where every component relies on the others.

End to End Trust? What about the often-discussed Trustworthy Computing initiative that Microsoft introduced in 2001? It’s still around but Microsoft realized that Trustworthy Computing alone may not be enough. So what else is needed? Craig Mundie mentioned:

At the time of his death, rumors had surfaced that Jackson was involved with a new video game project for the
Nintendo Wii,
PlayStation 2, and PlayStation 3, but the game was never officially confirmed.

The music in the home console version was a letdown for anyone who had played the arcade version–essentially MIDI-style pinky versions of tracks such as “Smooth Criminal” and “Beat It.”

While he was probably best-known for his personal eccentricities, pet monkeys, and legal problems (and some music, too, we suppose), Michael Jackson, who died Thursday at age 50, has a small but important footnote in video game history as well.

The game went on to become a cult classic, more for its cultural kitsch value than its gameplay, with its animated Jackson appropriated for funny Web videos and retro-’90s talking-head TV shows.

The arcade version was a basic isometric beat-’em-up, with two players able to play as dual Jackos, one in a white suit, one in red (similar to his “Smooth Criminal” music video). Jackson’s special attack was a dance move, and when activated, a spotlight from the heavens illuminated him as he pulled off some signature spins and kicks, destroying many of the onscreen enemies.

Subsequently, Jackson made only a handful of video game appearances, in Space Channel 5 (also from Sega) for the Dreamcast, and as an unlockable fighter in Ready 2 Rumble Boxing: Round 2.

News sites swamped following Michael Jackson’s death

Back when Jackson was merely a semi-eccentric star, Sega created a video game property for him, named Michael Jackson’s Moonwalker (actually separate games for the arcade and Sega Genesis/Master System consoles). Moonwalker was notable for being an early example of real-life celebrities appearing in video games, and for using digitized versions of some of Jacko’s songs.

The somewhat more pedestrian home console version behaved more like a standard side-scrolling platform game. Again we’re rescuing kids from a mobster, but the real appeal is hearing Jackson shout “Woo!” with each attack–usually a dance-like high kick that causes tiny stars to shoot from his foot.

Even stranger, Bubbles the Chimp made a cameo, and if you picked him up, Jackson would be briefly transformed into a laser-shooting robot version of himself.

The game is also unintentionally ironic because Jackson is tasked with rescuing helpless children from a crime boss named Mr. Big (although in hindsight, perhaps it was Mr. Big who was doing the rescuing).

These message boards include self-described groups of “pedos” who hacked into underage-girls’ private MySpace profiles. According to Poulsen, one poster reported successfully pilfering photos from a randomly chosen 14-year-old girl, “It worked and I was shown her pictures. Now lets see some naked sluts.”

Reporting kudos to Poulsen for staying on top of these emerging privacy concerns. I haven’t seen this story widely reported elsewhere, which is significant since public scrutiny and user concerns are the main points of leverage we have with companies like MySpace and its owner News Corp. to pressure them to devote sufficient resources to developing safe and secure products. Taken together with Facebook’s Beacon fiasco, breaches like these are sure to reinforce the impression that they still have a long way to go.

What’s more worrisome than a public MySpace page? A page that the user only thinks is private. I was just alerted to several stories by Kevin Poulsen of Wired News that publicize recent security breaches on MySpace.

Then on January 24, Poulsen reported that “A 17-gigabyte file purporting to contain more than half a million images lifted from private MySpace profiles has shown up on BitTorrent, potentially making it the biggest privacy breach yet on the top social networking site.”

On January 18, Poulsen updated the story to say that the next day, MySpace quietly fixed that back-door bug, without publicly acknowledging the problem, even though users’ profiles had been vulnerable for months.

Poulsen reported on January 17 about a MySpace Bug that leaks “private” teen photos to voyeurs. He wrote, “A backdoor in MySpace’s architecture allows anyone who’s interested to see the photographs of some users with private profiles–including those under 16–despite assurances from MySpace that those pictures can only be seen by people on a user’s friends list. Info about the backdoor has been circulating on message boards for months.”

But the Web site Ars Technica points out that the agency got answers from only about 66.7 percent of the 1,747 full-power TV license holders in the Federal Communications Commission’s database. The article notes that “while the report’s conclusions are still encouraging, the phrase ‘vast majority’ may be a tad overoptimistic.”

It’s estimated that there are 70 million or so analog TV sets that rely on over-the-air signals. And because many of these TVs belong to minorities, senior citizens, low-income individuals, and people who live in rural areas, the fear is that these individuals will not be ready for when broadcasters stop transmitting analog TV signals in February 2009.

The agency’s study also said some stations still had technical and logistical issues to work out before the February 17, 2009, deadline for making the big switch from analog to digital broadcast.

In February 2009, TV broadcasters will vacate wireless spectrum used to broadcast analog TV signals. Instead, broadcasters will transmit digital TV signals, which use spectrum more efficiently and provide better picture quality. The transition to digital means that some older TVs, and TVs with analog-only tuners, will have to be retrofitted to tune into digital signals.

The National Association of Broadcasters, which has already spent millions of dollars in efforts to educate the public, has said awareness is increasing. According to a new survey by the trade organization, almost 80 percent of households with a TV have at least some knowledge of the digital transition, up from 38 percent a year ago.

Under pressure from the FCC and lawmakers, broadcasters earlier this year agreed to run at least four advertisements a week during prime-time hours, along with a 30-minute show about the transition before the February 17 deadline next year, to educate the public about the transition.

The Government Accountability Office (GAO) report issued Tuesday said about 91 percent of the 1,122 full-power TV stations that answered their survey said they were already broadcasting a digital TV signal.

The transition to digital TV is going smoothly for broadcasters, according to a government report issued earlier this week. But lawmakers are still worried that consumers may still be confused or unaware of the change.

“Some of these stations still need to order equipment, such as antennas, to build their final digital facilities. Furthermore, stations may have coordination issues to address, to complete their final digital facilities,” the agency said. “Stations also need to coordinate with cable providers and satellite companies to ensure that cable and satellite facilities receive digital signals when the analog signals are turned off.”

“Broadcast stations have made substantial progress in transitioning to DTV, with the vast majority already transmitting a digital signal,” the GAO concluded.

While it looks like the TV broadcasters are on track to meet the deadline, some lawmakers worry that there is still confusion about what the digital transition means to consumers.

“Far too many Americans are unaware of, or unprepared for, February 17, 2009,” Senate Commerce Chairman Daniel Inouye (D-HI) said in a statement after the GAO’s report was released. “It is imperative that all stakeholders in the DTV transition, both public and private, work together to ensure that local communities are fully informed and prepared for the transition, and that no consumer is left in the dark.”

While TVs made after March 2007 will have digital tuners built-in, TVs made before then won’t. This means that some folks will have to either buy a new TV or get a digital-tuner box, which will be subsidized by the government. The government is already offering vouchers to help people buy these boxes.

AntiCNN.exe was the first of the two tools found on the Internet. Nazario reports that it opens a flood of HTTP connections and attempts to hurt the servers with volume.

Two toolkits designed to help ordinary people participate in denial-of-service attacks against Western media have surfaced on the Internet, according to one researcher.

Nazario says there is a third toolkit out, but it includes a backdoor back to its authors and could be used for other purposes.

Sdos.exe is the second tool. According to Nazario, “This one lets you specify a target server and a port, uses a simple connect() loop for the TCP flood.”

In a blog Tuesday, Jose Nazario of Arbor Networks says one of the toolkits is easier to use than the other though both are designed for “the masses.” This isn’t new, and toolkits such as these have been created for other political protests in the past.

DisplayPort is a rare, but powerful connection that has been heralded as the future of digital monitor connections.

As a follow-up to a monitor we recently reviewed, the NEC MultiSync EA221WM-BK, on Tuesday NEC announced the 23-inch NEC MultiSync EA231WMi.

4-way ergonomic stand (110mm height adjust, pivot, tilt and swivel)
Carbon footprint meter for tracking of carbon savings
DisplayPort, VGA, and DVI connectivity
Integrated four-port USB 2.0 hub
Down-firing built-in speakers with headphone jack
Built-in carrying handle

The EA231WMi knows how to render frogs.

Here’s a short list of additional features:

Additionally, the monitor includes a one-touch button for Eco Mode and features an ambient light sensor.

The EA231WMi will begin shipping in August 2009 with an estimated street price of $379. The display ships with a standard three-year parts and labor warranty, including the backlight.

The EA231WMi is a 16:9 aspect ratio monitor with a few notable improvements over the EA221WM-BK. First off, the new display uses an IPS-based panel as opposed to the TN panel the EA221WM-BK used. Also, the EA231WMi is the first NEC desktop display to feature a DisplayPort connection.

commentary

The technology has also been a hindrance, which Mr. Hilf says Microsoft tried to overcome by making additions to Windows Server 2008 that might appeal to Linux programmers who want better access to the technical guts of the software. Such changes “will be a big impact to that next-generation Facebook,” Mr. Hilf says.

Microsoft’s model is perfect for the client/server model that it helped to pioneer. It is irrelevant for the web-enabled future that is being built even as I type. This new world looks more like
Firefox: platform agnostic. It doesn’t care if people run Windows. Neither should you.

Well, no, Bill. Such changes are largely irrelevant at this point. You’ve already lost the mindshare war, and tepid changes to Microsoft’s server licensing policies won’t change things, either. Your company’s limp olive branch to the open-source community (”You can use our software royalty-free and without fear of legal retribution…so long as you never make a penny from your efforts”) is worse than insulting.

Microsoft hasn’t been a player in the Net start-up world, in part because of the cost of its server product. Mr. Hilf tells [the WSJ] that Microsoft is trying to fix that with new licensing schemes that make Windows Server more affordable for start-ups….

The rising generation of programmers isn’t being fed .Net and Windows. It’s growing strong on Linux and its associated LAMP stack, as Robert Guth of the Wall Street Journal notes. Microsoft thinks it has an answer to this trend toward Linux. It is very telling how far from reality Microsoft is by its response:
