Raspberry Pi A+ Details Leaked
It is garbage because a very closed CPU is used as an educational platform without datasheet availability.
This Broadcom SOC is great for mass-produced routers, bad for sharing with people trying to learn how Linux boots, learning assembly and possibly advancing to their own RTOS. I'm aware of the measly peripheral datasheet sections that are available online, but for Atmel and NXP chips one has to read a LOT more to make basic hardware level programs (how are the VICs nested, timing and boot issues/settings, other exceptions made by Broadcom i their ARM11 implementation etc).
Consistency is unimportant if youre giving people a board with the OS pre-installed, the kernel can handle different CPUs while users use different programs. But if you want to learn a bit more and go lower level (for example from Arduino), you're screwed by Broadcom SOC's severe lack of documentation. And forget about learning to code for the GPU.
When AIM Was Our Facebook
I was thinking the same thing. AIM was the first feeling of being online? Hell no! It was 9600 baud modems, BBSes and the first live chat for a lot of us was IRC.
I know I know unix has a chat thingy too, but it was IRC that connected the world, in strange little dungeon chatrooms, where you had to smell the bots before trying to download mp3s from them :)
Is Science Just a Matter of Faith?
When the first-ever reactor was being setup by Fermi, he know exactly how to build it and what the results will be. No human had ever built one before. And yet it was 'science' before the first reactor.
More than being 'testable', science gives you results rather than emotional satisfaction. There is much of science not testable (immediately) such as time travel and the likelihood of intelligent aliens in nearby galaxies.
A different definition might be:
- Science is the most likely truth given the observable
- Religion is usually the least likely truth, but one that emotionally appeals to us.
It was religion that claimed the world is flat, and sits on the back of a giant tortoise and a few other animals piled up. Science claimed the world was round before it was directly testable. It because testable when people sailed around the world. Yet there are still people in the 21st century who believe the world is flat, and they're being lied to.
Earth's Inner Core Rotation Slower Than Estimated
Holy assumptions in the original article. It links the core's relative rotation to the magnetic field. The magnetic field exists because a huge mass of ferroelectric material rotates.
Now which do you think affects the magnetic field more, the cores RELATIVE rotation speed (a few degrees in a million years?) or the overall Earth rotation (roughly 365 degrees in a day)? This is like putting a magnet in a plastic cup, rotating the magnet, and rotating the cup SLIGHTLY slower, and saying the resulting magnetic field is due to the cup rotating SLOWER.
Is the ISS Really Worth $100 Billion?
People in the ISS staring back at Earth while a huge asteroid wipes off the planet killing off all mammals would probably say "yup... that's some nice ROI.. good investing".
IEEE Releases 802.3ba Standard
Can you install Windows/Solaris/Linux/AIX on file-level storage, install Oracle/DB2/Exchange/Domino?
Block-level storage can and does completely replace local harddrives. Thats the reason for bladeservers, where blades have everything but harddisks. They're given volumes of fiber channel, iscsi or fcoe to become their local virtual disks. NFS or CIFS would be completely useless to them without first having block level volumes (except for the rare case of Linux/FreeBSD installed on NFS).
IEEE Releases 802.3ba Standard
I do not believe you've actually used iSCSI, at all.
The performance numbers are very different and so are the technologies, Microsoft filesharing is file-level and iSCSI is block level. It means with an iSCSI card, the machine can treat volumes as local disks and install any OS.
Secondly, you're confusing iSCSI with NFS. NFS has been freely available even back on Windows NT4. However it was not created to counter Microsoft, it was ALREADY there.
iSCSI until recently has been the only technology that provides block-level storage access and as efficiently as possible on a routable ethernet network. The recent FCoE is even more efficient but its not so easily routable.
IEEE Releases 802.3ba Standard
It's interesting how this will increase the adoption of iSCSI storage, yet the original reason to go to iSCSI will be lost since fiber cables will have to be laid.
Either way 1Gbit Ethernet is beginning to feel a bit like a bottleneck with storage and other bottlenecks being removed.
It'll take some time between ratification and cheap D-Link switches...

AdvancED Flash On Devices
I was so happy about a detailed book (700+ pages) on a 'flash on devices' book. I've been wanting to know more about the intricacies of flash chips before I put them on my dev boards. Embedded development gets far less attention regarding literature than web programming. ... and then I was let down. :) A book on flash chips (NAND, NOR, XIP, various voltages and tricks) will have to wait for a better day.
I hate flash.
Nokia To Make GPS Navigation Free On Smartphones
Yeah but does it have an aviation sixpack?
The aviation screen is just software, but Garmin charges an arm and a leg for it. It would be great to have a rough altimeter, airspeed indicator along with the map as a backup while up there.
Homemade PDF Patch Beats Adobe By Two Weeks
Since when has changing a registry entry become a 'hack'?
Next we'll hear of create-a-folder hack or waterfall screensaver hack.

Red Hat & AMD Demo Live VM Migration Across CPU Vendors
Declaration: VMware support engineering here, but speaking strictly on my own behalf.
The stability issues are justified if you consider all types of VMs. Windows 2003, default RHEL5 kernels etc use more than the basic set of assembler instructions (disk IO code uses MMX, SSE etc).
We can compile a kernel for strictly 486 CPUs and demonstrate migrations between AMD and Intel using extensive CPU masking: http://kb.vmware.com/kb/1993
We've also known that mismatched CPU stepping makes the VMs unstable. This is because instructions suddenly run faster or slower compared to the front side bus, not all of Linux and Microsoft code has been tested against that. You can happily try it and a lot of our customers succesfully do. Some get BSODs and kernel oops. This is not our fault.
If you virtualize the instructions more (bochs?) you can of course move the VM anywhere including a Linksys router's MIPS chip. At the cost of speed of course.
Lastly, why would we want to keep customers stuck to one CPU vendor? We've software vendors.
Fast-Booting Text-Editor Operating System?
If you need fancy text editing, use WordPerfect 7.
You can even find shortkey masks for standard keyboards, I still remember shift-7 prints.
Either way, Linux's boot-to-edit cannot come close to the speed of DOS. Especially with himem and emm386 disabled.
SGI Releases OpenGL As Free Software
I'm surprised that opengl was never really 'open'. It now makes sense why it wasnt a part of glibc and/or xfree86 until recently.
The opening of video card drivers and now opengl are major steps in the success of linux on the desktop (and for gamers).
Just imagine, we can now add opengl to Heretic and Command and Conquer, and it can all still be very much free. I can't wait for when I can port Halflife2 to Linux.
