Submission + - Debugging the FreeBSD kernal transparently

An anonymous reader writes: To debug the FreeBSD kernel core dump efficiently, it is best to set up a remote debugging session between the development machine and target machine, and remotely debug the kernel using serial communication. This article shows you how you can debug as many kernel images as you want to debug; it becomes transparent to users once debugging starts and your system's performance is not affected at all.

Submission + - UK shadow chancellor champions OSS

gdr writes: The BBC are reporting that The UK shadow chancellor George Osborne estimates that the government could save £600 million a year by using more open source software. He also complains about the lack of open standards in current systems stifling competition and hampering innovation.

Submission + - Scientists make electric components from shells

Matthew Sparkes writes: "Microscopic glass skeletons of algae could be transformed into silicon for novel electronic applications. Each replica is converted from silica to semiconducting silicon, and since the algae, known as diatoms, come in a huge variety of forms, the converted shells could have various potential applications. These could range from making microscopic gas sensors, to creating new kinds of batteries. Diatom shells are about 10 micrometres across and come in a variety of shapes — resembling barrels, donuts, triangles, and stars — with regularly sized features of 10 nanometres or smaller."
Censorship

Submission + - YouTube banned nationwide in Turkey

unity100 writes: "As of 07.03.2007, access to YouTube.com has been banned nationwide in Turkey through the nations' one and only internet backbone provider, Turkish Telecom, in accordance with decision no: 2007/384 dated 06.03.2007 of Istanbul First Criminal Peace Court.

The reason for this court's decision is a recent video that has been published on YouTube.com recently which is said to be insulting Turkish Republic's founder, Mustafa Kemal.

Curiously, this follows on the heels of a 3-4 month long campaign by the ruling party and the media supporting them against the freedom in the internet, citing "internet needs to be 'straightened up'".

All internet users nationwide are met with the below message that apparently emanates from Turkish Telecom DNS server or access filters :

"Bu siteye eriim mahkeme kararyla engellenmitir !...

www.youtube.com sitesine eriim stanbul 1. Sulh Ceza Mahkemesi'nin 2007/384 say ve 06.03.2007 tarihli karar gerei engellenmitir.

Access to www.youtube.com site has been suspended in accordance with decision no: 2007/384 dated 06.03.2007 of Istanbul First Criminal Peace Court.""

Submission + - Google's terabyte transfer system

An anonymous reader writes: Google has a system for shipping terabytes of information around the world. This system was brought about by following on the work started by by Microsoft researcher Jim Grey, who delivered copies of the Terraserver mapping data to people around the world. Google's open source team is working on ways to physically transfer huge data sets up to 120 terabytes in size. From the BBC article: "We have started collecting these data sets and shipping them out to other scientists who want them," said Google's Chris DiBona. The program is currently informal and not open to the general public. Google either approaches bodies that it knows has large data sets or is contacted by scientists themselves. One of the largest data sets copied and distributed was data from the Hubble telescope — 120 terabytes of data. "We have a number of machines about the size of brick blocks, filled with hard drives. "We send them out to people who copy the data on them and ship them back to us. We dump them on to one of our data systems and ship it out to people." Google keeps a copy and the data is always in an open format, or in the public domain or perhaps covered by a creative commons license.

Journal Journal: Using Google Adsense for Charity

I hope Slashdot-readers will help me generate more attention for this idea and come up with ideas to get this idea higher up Google's to-do-list. I have blogged about this on my blog. The origins of this idea lie in me looking at the enormous amount of $8 on my Adsense account (the payout limit is $100) and wondering if there was something better to do with it, instead of waiting 12 years for the first check.

Submission + - Pros and Cons of a Secondary MX?

brad-x writes: "From the article:

"Many sites use multiple MX records in DNS. But i feel like i'm seeing more and more which just have a single MX record. Why choose the one strategy over the other?

Given that MTAs are increasingly complicated these days (with various spam filtering techniques), what are some good arguments for (or against) having multiple MX records for a relatively small domain (1000 users)? Here's a couple notes of my own (which i'm not wedded to: please tell me if you disagree!)""

Submission + - Hide secret messages in images on the internet

Andrew Lee writes: "This program lets you hide arbitrary text messages inside image files. It is different than other stego tools in that it encodes the message by making visible changes to the image, rather than encoding the message in non-visible parts of an image file's data. In theory you can even print out the image and scan it back in to retrieve the secret message.

Submission + - Vista Download Disaster

SkinnyGuy writes: "Downloading Windows Vista sounds like a great idea — until you actually do it. Looks like Microsoft hasn't thought out all the fine details. PC Magazine's own publisher gave it a shot and recounts his sorry tale to columnist Lance Ulanoff. Some other tales of woe appear in the associated forum."

Submission + - Slashdot Funnies

R3d M3rcury writes: I was going through the links in the 'Funnies' section and I found that a bunch seem to have been discontinued.

Mikey — Appears to have been taken over by a squatter.
Dr. Fun — Has been discontinued.
After Y2K — Updating sporadically at best. Looks like the last one was in 2004.
Helen — Ended at the end of last year.

Also, the Fifth Wave has moved to http://www.gocomics.com/thefifthwave/

Anyway, it might be time to clear out those five. Perhaps replace them with AppleGeeks, Ctrl+Alt+Del, Joy of Tech, Sheldon, and Evil, Inc.. Of course, that's just my list. What other comics do people think would be entertaining for Slashdot readers?

Submission + - I violated copyright law. Now what?

An anonymous reader writes: I am US-based and have recently been doing part-time subcontracting work for a friend in the UK who runs her own small marketing firm. She sells a complete branding/identity plan and if that includes a web site refresh, she calls me. The clients do not know who or where I am, or even that the work is being subbed. Like many designers, I often use Corbis and other photo merchants to mock up layouts for review. It is legal to download images ("comps") from Corbis to use offline for the this purpose. If the client likes the design/images, I get a quote from the photo vendor and the client has the option to purchase. If the price is too high, which it often is with Corbis, I turn to less expensive or free alternatives.

One of her clients, for whom I recently designed a site, just received a $25,000 invoice from a law firm in London representing Corbis, who claimed their content was on the client's site. The client of course was frantic when they received the bill and called my marketing friend, who called me. I investigated and sure enough, there were images on the site that were rightfully the property of Corbis, which I put there. In this instance I neglected to swap out the comps with legal images I purchased for the client from another online source before I made the site live. As a designer I respect content rights and did not, would not, maliciuosly steal images. The client and my friend had no idea.

I moved quickly to correct the situation — scrubbed the site and looked through other clients' sites to make sure nothing else had gotten through. I called Corbis and told their legal department what happened and they told me I would have to deal with the law firm, who handles "all our overseas affairs." I then sent a certified letter to the law firm telling them what happened in an attempt to exonerate the client, and by default, my friend. That was today.

I quoted the images in question on the Corbis site and the total would have been about $800. I did my due-googling and in the spectrum of copyright infringement, I want to believe I'm closer to the speeder than I am the serial-killer. Other photo houses (Getty) send out cease and desist letter and it's done. There is mention of similar situations on some forums, especially in the UK, but I can't seem to find any precedent as to what my fate might be. Does anyone have any idea? I made about $1,000 for the site about a year ago, and as much as it would pain me, would be willing to give that up to make this go away. But something tells me this is going to get ugly.
