Comment: Re:Will it have the same garbage CPU? (Score 4, Insightful) 141

by mnmn (#48345453) Attached to: 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.

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 :)

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.

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.

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).

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.

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...

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.

+ - Fuel Cell Car and Experiment Kit

Submitted by
Anonymous Coward
Anonymous Coward writes "Kids can't help but get excited about saving the planet when they see their own model car zoom across the floor powered by nothing but water! Fuel-cell technology is the environmentally friendly wave of the future. The water becomes fuel before kids' eyes as electrolysis (powered by a solar cell) breaks it into its separate components of hydrogen and oxygen, creating a gas that is then stored for use by the fuel cell when it's time for the car to get going. During the building process, children from age twelve can use the included 96-page Experiment Manual as a guide to performing thirty experiments on such subjects as the effects of direct and indirect radiation, the characteristics of a solar module, constructing and loading a reversible fuel cell, and decomposition of water in the fuel cell, plus they can design experiments of their own. The kit contains everything children need to build and experiment with their fuel cell and car (except 1 quart of distilled water)."

+ - Modern Day Witch-Hunt in Connecticut

Submitted by zhenya00
zhenya00 (972438) writes "USAToday is reporting on a story most of us are already familiar with; the case of Julie Amero, a 40 year old Norwich, Connecticut substitute teacher who has been convicted of four counts of risk of injury to a minor when the un-patched Windows 98 computer she had used to check her email began to display a flurry of pornographic pop-ups to the students in her classroom. She faces up to 40 years in prison when she is sentenced this Friday March 2.
From the article:

"Julie Amero was a victim of a school that couldn't be bothered to protect its computers, of a prosecutor without the technology background to understand what he was doing, a police "expert" who was not, and a jury misled by all of them. "Miscarriage of justice" doesn't begin to describe it."
Can this country really allow something like this to happen? Why isn't there general outrage on the front page of every newspaper? Why aren't those responsible being flooded with calls and emails from angry citizens?"

Is it possible that software is not like anything else, that it is meant to be discarded: that the whole point is to always see it as a soap bubble?
