toomuchtoomuchspam writes "According to Websense, Microsoft's CAPTCHA has been busted again. CAPTCHA was surely a logical move for different service providers to fight against spammers, but it seems to be melting down. 'Realizing the potential for massive abuse from spammers with anti-CAPTCHA capabilities, who could use the clean IP reputation to carry out various attacks over Email and Web space, Microsoft attempted to increase the complexity of their CAPTCHA system. The CAPTCHA system was revised in an attempt to both prevent automatic registrations from computer programs or automated bots, and preserve CAPTCHA's usability and reliability. As this attack shows, those efforts have failed,' says Websense security researcher Prasad. Could there be any better CAPTCHA? A better solution?"

For the last 10 years, I have been asking people more knowledgeable than I, "How big should my swap be?" and the answer has always been "Just set it to twice your RAM and forget about it." In the old days, it wasn't much to think about — 128 megs of RAM means 256 megs of swap. Now that I have 4 gigs of RAM in my laptop, I find myself wondering, "Is 8 gigs of swap really necessary?" How much swap does the average desktop user really need? Does the whole "twice your RAM" rule still apply? If so, for how much longer will it likely apply? Or will it always apply? Or have I been consistently misinformed over the last 10 years?

Ian Lamont writes "The recent news that China will run out of IPv4 addresses in a few years points to slow adoption of IPv6 in some developed countries. Now it turns out that the largest number of networks displaying new IPv6 address blocks are registered through AfriNIC, which services networks in Africa and the Indian Ocean. While AfriNIC has a smaller installed base than other regions, many countries in Africa are showing rapid growth in terms of online connectivity."

CWmike writes "Within a month, Microsoft will unveil what CEO Steve Ballmer called 'Windows Cloud.' The operating system, which will likely have a different name, is intended for developers writing cloud-computing applications, said Ballmer, who spoke to an auditorium of IT managers at a Microsoft-sponsored conference in London. Ballmer was short on details, saying more information would spoil the announcement. Windows Cloud is a separate project from Windows 7, the operating system that Microsoft is developing to succeed Windows Vista."

ancientribe writes "Hacker RSnake blogs about a newly discovered and deadly denial-of-service attack that could well be the next big threat to the Internet as a whole. It goes after a broadband Internet connection and KOs machines on the other end such that they stay offline even after the attack is over. It spans various systems, too: the pair of Swedish researchers who found it have already contacted firewall, operating system, and Web-enabled device vendors whose products are vulnerable to this attack." Listen to the interview (MP3) — English starts a few minutes in — and you might find yourself convinced that we have a problem. The researchers claim that they have been able to take down every system with a TCP/IP stack that they have attempted; and they know of no fix or workaround.

Croakyvoice writes "Finally, months after the official announcement, 3,000 lucky people can now pre-order Pandora, possibly the world's fastest handheld console. It boasts a processor capable of up to 900 MHZ, PowerVR 3D graphics, a large 800x480 LCD touchscreen, Wi-Fi, Bluetooth, USB, dual SD card slots, TV out, dual analogue and digital controls, a clamshell DS Lite-style shape, and a 43-button mini keyboard. The console already boasts an amazing amount of ready-for-release software such as Ubuntu and many full-speed emulators for systems such as Snes, Amiga, Megadrive, and many more that are not publicly announced yet. The console is as powerful as the original Xbox and on a par with the Nintendo Wii. Those interested should visit OpenPandora.Org. For the full history of Pandora from inception until the present, check out the Pandora Homebrew Site."

James Harold writes "Today NASA unveiled a new infrared mosaic of our galaxy. The result of over 800,000 individual images collected by the Spitzer Space Telescope, it is the largest, highest-resolution, and most sensitive infrared picture ever taken of the Milky Way (and will likely remain so for the foreseeable future). Because Spitzer sees in infrared, it penetrates much farther into the galaxy, revealing previously hidden star clusters, star-forming regions, shocked gases, glowing 'bubbles' and more. The complete mosaic is about 400,000 by 13,000 pixels, and a 180' printed version is being shown at the American Astronomical Society meeting in St. Louis. A zoomable, annotated version of two different variants on the image (as well as some additional information on the science) is available at Alien Earths, a NASA- and NSF-supported education site." The Spitzer survey is already causing a stir potentially bigger than that raised when Pluto was deemed not a planet: two minor spiral arms of the Milky Way may be demoted.
