Comment: Older than 15 years (Score 1) 543

by dolphinling (#32068692) Attached to: How Old Is the Oldest Computer You Regularly Use?

I semi-regularly ssh into a server that's running linux 2.2, and AIUI the home directories for that and the desktops in the building (that I do use regularly) are served off an ancient SGI mainframe. I also regularly use a server running AIX 5.3; I have no idea how old the hardware for that is (AIX 5.3 came out in 2004).

Thus, I'm reasonably sure 15+ years old is not an overstatement. Yay for universities.

That said, even my desktop is over 6 at this point.

Hard to say. I'm pretty sure the 3 second time had a lot of "typical" linux components stripped out, but note that you won't get a shell until everything's finished loading, while X can be started in parallel with other things and be usable while other components start. I believe some work was done that got it under 5 seconds from init to usable. There's still the bios time (0 with a tricked-out coreboot setup) and the time while the kernel starts up before init (this takes 2-3 seconds for me, no idea what "normal" or "fast" is). That adds up to ~7-8 seconds.

One thing to note is that storing the kernel directly in EEPROM lets you skip the bootloader entirely. Bootloaders are usually pretty fast, but they usually have a programmed delay of a few seconds to let you choose a kernel or whatever.

I'd say media files (and software, too) expand to take up as much space as internet bandwidth allows. Back in the day, if you wanted online video, it was all tiny .mpgs. Now it's HD Theora and H264. Back when I had dialup, I wouldn't have appreciated it if the only way to watch something was to wait 7 weeks for it. Now, I can get that same file in a few hours and that's an acceptable time to wait.

And of course, very much involved is packrat tendencies: we'd much rather buy another hard drive than have to delete stuff, even if we're done with it.


+ - OGP releases video of VGA emulator booting-> 1

Theovon writes "Slashdot hasn't seen much news about the Open Graphics Project for some time now, but the OGP has been quite busy, especially recently. As you may recall, the OGP's goal is to develop a fully open-source graphics card. All specs, designs, and source code are released under Free licenses. Right now, they're using FPGAs (large-scale reprogrammable chips) to build a development platform that they call OGD1. And they've just completed an alpha version of legacy VGA emulation, apparently not an easy feat. They have posted a Youtube video of OGD1 driving a monitor, showing Gentoo booting up in a PC. This completes a major step, allowing OGD1 to act as the primary display in an x86 PC. The announcement can be seen on the OGP home page, and there's an article. Finally, the Free Software Foundation has taken notice of this and is asking for volunteers to help with the OGP wiki."

Debian Gets FreeBSD Kernel Support 425

Posted by timothy
from the types-like-this-kept-me-out-of-good-schools dept.
mu22le writes "Today Debian gets one step closer to really becoming 'the universal operating system' by adding two architectures based on the FreeBSD kernel to the unstable archive. This does not mean that the Debian project is ditching the Linux kernel; Debian users will be able to choose which kernel they want to install (at least on on the i386 and amd64 architectures) and get more or less the same Debian operating system they are used to. This makes Debian the first distribution, and probably the first large OS, to support two completely different kernels at the same time."

Huh. I dropped my OLPC from about 4 feet (a little less, maybe 3.5 with some forward momentum too) just a week ago. It bounced to about 1.5-2 feet, then landed again. Outdoors, hard asphalt. No damage except a tiny depression in the plastic on one corner.

Not the first time I've dropped it, either. Only thing I've broken from a drop is a tiny chunk of plastic off the headphone jack--in a ~6 foot drop onto a tile floor that hit the wall and my leg and thus didn't get the full force, but did manage to bend the 1/8th inch headphone connector.

Sounds like Dell has some catching up to do.

A book that I liked when I was younger was To Infinity and Beyond by Eli Maor. It's a sort of advanced layman's look at infinity and the closely-related zero. It includes mathematical topics your students probably haven't seen before (and won't, unless they become math majors), in enough depth to be interesting but not overwhelming (not enough to really be useful mathematically, either just to make them interested and perhaps help them be more comfortable if/when they get to higher math). It also has a lot of history. It seems to be mostly available on google book search (a bunch of random pages missing, but mostly there) so you can check it out without leaving your computer!

Adobe To Open Real-Time Messaging Protocol 108

synodinos writes "Adobe has announced plans to publish the Real-Time Messaging Protocol specification, which is designed for high-performance transmission of audio, video, and data between Adobe Flash Platform technologies. This move that has followed the opening of the AMF spec has been received with varying degrees of enthusiasm from the RIA community."
