How To Verify CD-R Data Retention Over Time? 303

Peter (Professor) Fo writes "I've recently had two CD-Rs reported to me as faulty which are just 3 years old. This is worrying — I suspect the failure rate for this batch could be 10%. When researching CD longevity there is old and unreliable information; pious 'how to cosset your discs so they last 100 years' blurb; and endless discussions of what sort of dye to use, don't use cheap media, burn slower (or don't), but not much by way of hard facts besides there's a lot of data loss going on. Does anyone know of a generic utility (win or *nix would suit me) that can map sector readability/error rates of CDs? I'd like to measure decay over time in my environment with my media and my other variables; and I expect others would too."

LHC Forces Bookmaker To Lower Odds On the Existence of God 457

A UK bookmaker has lowered the odds on proving that god exists to just 4-1 to coincide with the switching on of the Large Hadron Collider. The chance that physicists might discover the elusive sub-atomic object called the "God particle" has forced the odds lower. Initially the odds that proof would be found of God's existence were 20-1, and they lengthened to 33-1 when the multi-billion pound atom smasher was shut down temporarily because of a magnetic failure. A spokesman for Paddy Power said, "The atheists' planned advertising campaign seems to have renewed the debate in pubs and around office water-coolers as to whether there is a God and we've seen some of that being transferred into bets. However we advise anyone still not sure of God's existence to maybe hedge their bets for now, just in case." He added that confirmation of God's existence would have to be verified by scientists and given by an independent authority before any payouts were made. Everyone getting a payout is encouraged to tithe at least ten percent.

Games To Outsell Music, Video In UK 47

The BBC reports that for the first time, spending on games and game hardware will outstrip sales in the music and video industries. Quoting: "In the last five years the video games market has more than doubled in value, while music sales have stagnated. The good news for game makers in the report was balanced by grim tidings for high street retailers. 'The music and video market is not just suffering from a slowing of growth but a massive transfer of spend to online,' says Malcolm Pinkerton of Verdict Research. It is online sales of CDs and DVDs that have grown rapidly, rather than digital downloads, which still only account for around 4% of music and video sales."

(Useful) Stupid Unix Tricks? 2362

So the other day I messaged another admin from the console using the regular old 'write' command (as I've been doing for over 10 years). To my surprise he didn't know how to respond back to me (he had to call me on the phone) and had never even known you could do that. That got me thinking that there's probably lots of things like that, and likely things I've never heard of. What sorts of things do you take for granted as a natural part of Unix that other people are surprised at?

Barack Obama Wins US Presidency 3709

Last night, around 11pm, all the major networks announced that Senator Barack Obama had won the election. Soon after, Senator McCain conceded. There were no crazy partisan court hearings, just a simple election. This is your chance to talk about it and what it means for the future of our nation.

Reuse Code Or Code It Yourself? 429

eldavojohn writes "I began coding for a project that had simple requirements for my employer — Web services and a test application for them. But requirements have been creeping, as they always do. Initially I had decided to use the Spring Framework with Hibernate. And I re-used a lot of libraries that made things simple and quick for me. The new requests coming in involve capabilities beyond those of the frameworks. Now, I used to be told that good programmers write code and great programmers reuse code. It's starting to look like I would have saved myself a whole lot of time if I had written the database transaction using JDBC instead of Hibernate — now that I'm married to this object model framework, some of this stuff doesn't look doable. So what is better for the majority of software projects out there: reuse code, or code from scratch? What elements or characteristics of a problem point to one option over the other?"
Wireless Networking

Low-Bandwidth, Truly Remote Management? 215

kaiser423 writes "I'm looking to integrate some highly critical solutions into what would essentially be a remote, moving datacenter. No operators will be allowed at the site, and we may be able to have a high-speed INMARSAT data link. As a backup, we're planning to have multiple redundant low-speed Iridium data links. Essentially, we're looking to be able to power up/down and reboot some computers, and be able to start/stop some programs. We're willing to write the terminal interfaces necessary for our programs, and possibly do the remote desktop thing with some of our 3rd-party programs. But what is out there that would give us this type of access, work robustly over a high-latency, low-bandwidth stream, and would be tolerant to intermittent network outages? Please hold the pick 2 of the 3 jokes, I know they're contradictory goals; I'm looking for a compromise here! These boxes would regrettably nearly all be running Windows (with some VxWorks). Does anyone out there remember those days, and have any solutions that they preferred?" Read on for a few more details of this reader's requirements.

Inventor Open Sources "TV-B-Gone," and Why 340

ptorrone writes "Inventor Mitch Altman explains why he open-sourced his TV-B-Gone kit, the original stealth keychain fob for defeating TVs in public places. The title of the article is 'Patent-B-Gone' and perhaps the most interesting fact is that Mitch's brother is a patent attorney, but he still decided to release an open source hardware version of the TV-B-Gone, with pretty impressive results."

Portable Solar Power For Portable Hardware? 262

Tjeerd writes "Because the 'green revolution' is accelerating, I felt it was time to get involved. Last week I started with buying a portable solar energy charger for my mobile phone. But soon I was thinking of also recharging my Asus Eee netbook with a portable solar energy recharger. I found things like the Portable Power Pack, Foldable Solar Chargers, and the Solar Gorilla. The Solar Gorilla looks quite interesting and might be able to recharge my netbook and fits nicely in a rucksack. But I would like some real-life feedback. If you have experience with these or other portable solar devices, what has worked for you?"

Wayland, a New X Server For Linux 487

An anonymous reader writes "Phoronix has a new article out on Wayland: A New X Server For Linux. One of Red Hat's engineers has started writing a new X11 server around today's needs and to eliminate the cruft that has been in this critical piece of free software for more than a decade. This new server is called Wayland and it is designed with newer hardware features like kernel mode-setting and a kernel memory manager for graphics. Wayland is also dramatically simpler to target for in development. A compositing manager is embedded into the Wayland server and ensures 'every frame is perfect' according to the project's leader."

Programming .NET 3.5 224

lamaditx writes "The world of the .NET framework is taken to the next level by the release of .NET 3.5. The intended audience of this book are experienced .NET programmers. There are no sections that tell you details about C#, SQL servers or anything like that. I don't recommend this book if you never worked on a .NET project and don't know how to set up a SQL database. You should be aware that the code is written in C#. You might use one of the software code converters if you prefer Visual Basic instead. I think the code is still readable even if you do not know C#. I appreciate the fact that the authors decided to use one language only because it keeps the book smaller. The authors assume you are using Visual Studio 2008. You don't necessarily need to update to 2008 if you are working with an older edition because you can use the free Express Edition to get started." Keep reading for the rest of Adrian's review.

Intel Core I7 Launched, Nehalem and X58 Tested 194

MojoKid writes "Today marks the official launch of Intel's new Core i7 processor, the most major overhaul of Intel's core processor architecture since the release of their Core 2 design. As has been reported, the Core i7 is a major departure from Intel's aging Front Side Bus architecture of old, now replaced by Intel's QPI (Quick Path Interconnect) serial links. This 20 lane bi-directional (40 lanes total) point-to-point connection provides 6.4 GT/s of bandwidth and scalability for future multi-socket designs as well. In addition, the Core i7 now has an integrated triple channel memory controller offering over 3X the bandwidth of the previous Core 2 architecture with DDR3 system memory. Though the product is set to ship in volume later this month, the early benchmark numbers show Intel's new chip is markedly faster clock-for-clock versus their previous generation CPU and much faster than anything AMD has out currently."

How To Make Money With Free Software 81

bmsleight writes "The Dutch Ministry of Finance organized an architecture competition to design not a building, but rather the new 5-Euro commemorative coin. The theme was 'Netherlands and Architecture'. The winning design was made 100% with free software, mainly Python, but also including The Gimp, Inkscape, Phatch, and Ubuntu. The design is amazing — the head of Queen Beatrix is made up of the names of architects based on their popularity in Yahoo searches (rendered in a font of the artist's own devising). In the end the artist, Stani Michiels, had to collaborate closely on location with technicians of the Royal Dutch Mint, so all the last bits were done on his Asus Eee PC. Soon, 350,000 Dutch people will use and enjoy the fruits of free software."

D.I.Y. Home Security 377

theodp writes "The NYTimes reports that pre-wired home security installations by alarm companies are on the way out. Thanks to wireless window and door sensors and motion detectors, installing and maintaining one's own security system is becoming a do-it-yourself project, with kits available from companies like InGrid and LaserShield. Time to start cranking out some new iPhone and Android apps, kids?"

Windows 7 To Be 256-Core Aware 441

unassimilatible writes "As new features of Windows 7 continue to trickle out, ZDNet is now reporting that it will scale to 256 processors. While one has to wonder, like with Vista, how many of the teased features will actually make it into the final OS, I think we can all agree, 256 cores is enough for anybody." This Mark Russinovich interview has some technical details (Silverlight required).
