What's wrong with AoE? It's high performance, low-overhead, and simple. We're looking at using KVM, or Xen. Xen PV has much better performance compared to our current ESXi cluster. I think our ESXi cluster is on FC + 1GE + HP Blades. We can get far better performance from Xen by using DAS and replicating it up to a AoE store in case of local drive failure. Drive latencies are 1/10th of what they are on FC, and we're able to get much better IOPs from using local SSDs. Our systems, and TCO is far lower cost by using commodity Dell hardware instead. Last company I was at had something like 500 TB aggregate storage, and 18 racks. We have over 100 Gbit/sec of aggregate bandwidth on our cluster. I'd say probably 25 gbit/sec of that was storage traffic. I'd like to see you try to meet that scale with a traditional FC SAN.

I live in Scotland, and I recently signed up with an ISP that did this. They have block control over my building, so there wasn't any other solution. They have a device (I'm pretty sure it's just a linux box based on my nmapping) that looks at each packet's TTL. If the TTL is odd and the port is NOT 80 or 443, it drops the packet. If the TTL if odd and the port is 80 or 443, then it redirects you to a billing page. I bypassed it by incrementing TTL at my gateway. I imagine people will modify openwrt/dd-wrt to do this as well. Additionally, I have a solution which tunnels my connection over a VPN to an Amazon EC2 instance and does some magic to beat QoS. It seems like oversubscribing at at least 2000% seems typical. I'm paying for a 50 mbit/sec connection. I see closer to ~6-8 mbit/sec (no, I'm not getting my megabytes and bits confused). Additionally, since I know a little about my ISP internally, they run all these blocks to their HQ over MetroE-like products, and then concentrate it into their core. Their transit is 10GigE (based on traffic numbers pulled from various private sources). I know that they sell far more than 10GigE of bandwidth to customers. There is far more wrong with the ISP environment here than you'd know. My girlfriend's ISP is even worse. They do a significant amount of throttling on specific ports (1935, 80, so on..) and basically any kind of download during the day slows down to a halt. They have about 6000 people + several offices on a 10 GigE connection. I don't know if this will even be seen, but I thought it was worth throwing out there.

Anonymous Now Attacking Corporate Fax Machines 410

An anonymous reader writes "Anonymous has claimed responsibility for distributed denial of service attacks against several anti-WikiLeaks websites this month. In a novel twist to the campaign, Mission Leakflood has started a new DDoS attack against fax numbers belonging to Amazon, MasterCard, Moneybookers, PayPal, Visa and Tableau Software. Some numbers have already stopped responding, and Twitter and PostFinance have since been added to the target list."

Venture Capitalists Lobby Against Software Patents 127

ciaran_o_riordan writes "No matter which side the US Supreme Court's Bilski decision pleases, it will be just the beginning of the software patent debate in the USA — the other side will start a legislative battle. The lobbying has already begun, with venture capitalist Brad Feld arguing against software patents, mailing a copy of Patent Absurdity to 200 patent policy setters. As Feld puts it, 'Specifically, I'm hoping the film will bring you to an understanding of why patents on software are a massive tax on and retardant of innovation in the US.' The patent lawyers and big patent holders often tell us that patents are needed to secure investment, so it's interesting to see now that venture capitalists are refuting that. And Brad Feld isn't the only vocal one; there's a growing list."

Planck Satellite Reveals Star Formation Processes 29

An anonymous reader writes "New images from the Planck Space Observatory reveal the gas and dust between the stars and isolate the physical processes at work in our galaxy. The new images are an eye-catching by-product of a spacecraft designed to look back at the earliest light in the universe. ... When observed at much longer wavelengths, where the cosmic microwave background can be seen, the picture is very different, as clearly demonstrated in new images from ESA's Planck mission. The dust is no longer a dark shroud, but shines out in its own right, and new aspects of our galaxy are revealed."

Man Uses Drake Equation To Explain Girlfriend Woes 538

artemis67 writes "A man studying in London has taken a mathematical equation that predicts the possibility of alien life in the universe to explain why he can't find a girlfriend. Peter Backus, a native of Seattle and PhD candidate and Teaching Fellow in the Department of Economics at the University of Warwick, near London, in his paper, 'Why I don't have a girlfriend: An application of the Drake Equation to love in the UK,' used math to estimate the number of potential girlfriends in the UK. In describing the paper on the university Web site he wrote 'the results are not encouraging. The probability of finding love in the UK is only about 100 times better than the probability of finding intelligent life in our galaxy.'"

Slovak Police Planted Explosives On Air Travelers 926

Entropy98 writes "Slovakian Police have planted explosives on 8 unsuspecting air travelers. Seven were stopped by airport security, including one man arrested and held upon arriving at a Dublin airport. Unbelievably, one innocent traveler made it home with 90 grams of explosives, and had his flat surrounded by the police and bomb squad."

Shuttleworth Suggests 1-Way Valve For User Experience Testing 757

darthcamaro writes "No surprise but Ubuntu's Mark Shuttleworth has come out swinging in favor of the Linux desktop. Speaking at Linuxcon yesterday he detailed the things that he thinks Linux requires in order to win the desktop wars. Those include: co-ordinated software releases, better quality and design, some user experience testing and oh yeah, a dose of 'shut the f*** up' too. During his keynote, he extended an invitation to any open source application to submit their software for testing by user-experience experts. The sessions would be recorded for posterity, and the developer would not be able to interact with the user. "'If the developer is in the room, they have to say nothing. It's the shut the f*** up protocol,' Shuttleworth said. 'You sit and watch someone struggle with the software that you've so lovingly produced.'"

Local Privilege Escalation On All Linux Kernels 595

QuesarVII writes "Tavis Ormandy and Julien Tinnes have discovered a severe security flaw in all 2.4 and 2.6 kernels since 2001 on all architectures. 'Since it leads to the kernel executing code at NULL, the vulnerability is as trivial as it can get to exploit: an attacker can just put code in the first page that will get executed with kernel privileges.'"

Pandora Wants Radio Stations To Pay For Music, Too 253

suraj.sun sends along an Ars writeup of the lobbying Pandora is doing now that it has secured its future, royalties-wise. Some might think it odd that Pandora is weighing in on the side of the record labels in their fight to get radio stations to pay more for the music they broadcast. "US radio stations don't pay performers and producers for the music they play, but the recording industry hopes to change that with a new performance rights bill in Congress. Webcaster Pandora has jumped into the fray on the side of the artists and labels, asking why radio gets a free ride when Pandora does not. ... With revenues from recorded music sales declining, rights-holders have turned their eyes in recent years to commercial US radio, which currently pays songwriters (but not performers or record labels)... With its own future secure for the next few years, Pandora is now turning its attention to the public performance debate here in the US, saying that the issue is a simple matter of fairness: why should webcasters have to pay more for music than traditional radio does? ... [But] the 'fairness' argument could clearly go either way. Radio might start paying a performance right; on the other hand, perhaps webcasters and satellite radio companies should simply stop paying one, relying on the old argument about promotion."

Google Releases Open Source NX Server 257

wisesifu writes with news of a new open source NX server, dubbed NeatX, that was released by Google and promptly lost in the shuffle of the Chrome OS announcement. "NX technology was developed by NoMachine to handle remote X Window connections and make a graphical desktop display usable over the Internet. By its own admission, Google has been looking at remote desktop technologies for 'quite a while' and decided to develop Neatx as existing NX server products are either proprietary or difficult to maintain. 'The good old X Window system can be used over the network, but it has issues with network latency and bandwidth. Neatx remedies some of these issues,' Google engineers wrote on the company's open source blog. NoMachine had released parts of the source code to its NX product under the GPL, but the NX server remained proprietary. [...] Neatx is written in Python, with a few wrapper scripts in Bash and one program written in C 'for performance reasons.'"
