Submission + - EOMA68 Modular Eco-Computing Project launches on Crowd Supply (crowdsupply.com) 6

lkcl writes: An ambitious project running for the past five years to create eco-conscious cost-saving user-upgradeable computing appliances has just launched on Crowd Supply, with a 15.6in laptop housing and micro-desktop housing, with the first Computer Card in the series using an ultra-low-power Allwinner A20 Dual-Core ARM processor. Two main OSes are currently available: Parabola GNU/Linux-libre which is FSF-Endorsed: RYF Certification is being applied for, and Debian GNU/Linux is also available. The sponsors of the laptop housing — Thinkpenguin — have more about the privacy issues at their blog, Liliputing has an article, and Freedom's Phoenix Radio has a live interview with Ernest Hancock.

Comment Re:Fractint (Score 1) 131

Is there anything better than Fractint now? I too played with it for ages on a clunky old IBM PC with clicky keyboard and Windows 2 (although Fractint ran in DOS though, I think, and necessitated misc tweaking with graphics drivers to make it work, you kids don't know how lucky you are...)

You have the open-source "xaos" http://xaos.sf.net/ for a fast interactive fractal exploring and "Fraqtive", http://fraqtive.mimec.org/ for a beautiful view generator. Also, there are new versions of fractint, but the UI is really outdated. Wikipedia has a list with a few more, at http://en.wikipedia.org/wiki/Fractal-generating_software

Comment Re:Turbo Boost technology? (Score 5, Informative) 196

Seriously, couldn't the marketing droids come up with a better name?

Sadly, this technology was called "Intel Dynamic Acceleration" (IDA) in Core-2 CPU's, but nobody noticed it. So, Intel tried with "Dual Dynamic Acceleration" (DDA), but again, nobody noticed. At last, renamed it to "Turbo Boost" and now everybody thinks it's something new.

So, after three attempts, it seems that the current name is the best.

Comment Re:/tmp and /var/tmp (Score 3, Interesting) 303

-- but they failed to point out that Solaris also has a /tmp, and that, by default /tmp is actually partially backed by RAM, which is extremely convenient and useful from time to time, when you want a little piece of lightning-fast filesystem space, or want to eliminate disk as a variable in some sort of timing test.

In any new Linux distribution, /dev/shm is also backed by ram, so you can do:

$ dd if=/dev/zero of=/var/tmp/foo bs=1024k count=512
512+0 records in
512+0 records out
536870912 bytes (537 MB) copied, 1.12253 s, 478 MB/s


$ dd if=/dev/zero of=/dev/shm/foo bs=1024k count=512
512+0 records in
512+0 records out
536870912 bytes (537 MB) copied, 0.754747 s, 711 MB/s

Obviously, I had to copy four times the data to reach the slowness of Solaris :-)

The Courts

Submission + - NVIDIA Countersues Intel Over License Conflict (hothardware.com)

MojoKid writes: "After Intel filed a lawsuit against NVIDIA late last month, alleging that a four-year-old chipset license agreement the companies signed did not extend to Intel's future generation CPUs with "integrated memory controllers" (like Nehalem), NVIDIA decided to fight fire with fire. Today, NVIDIA filed a countersuit in the Court of Chancery in the State of Delaware against Intel Corporation for breach of contract. Furthermore, the action also seeks to terminate Intel's license to NVIDIA's valuable patent portfolio, which no doubt is reverberating with some level of intensity in the halls of Intel. According to NVIDIA, the countersuit was "brought in response to a filing by Intel last month in the Delaware court", which is no doubt in rebuttal to the skirmish that Intel initiated last month."
NASA

Submission + - Effects of the Top Layer of Mars' Soil

nlhouser writes: "The Mars Odyssey orbiter has been showing the scientists more detailed pictures at variable depths on Mars, more detailed than previously available. Plans are that the next 2008 Mars mission of NASA, the Phoenix Mars Lander, will find different ice depths next to each other instead of in different locations long distances apart. According to the Arizona State University research specialist, Joshua Bandfied, "We find the top layer of soil has a huge effect on the water ice in the ground.""
