This is what is happening:

1. Because of signals like the ocean getting more, scientists know the earth's temperature has been rising.
2. An event happens (snow, hurricane, etc.) 3. Scientists decide said event might have happened because the earth is getting warmer.

This is suspicious, but even if these events are being incorrectly classified as side-effects of global warming, that does not disprove global warming.

What NAS To Buy? 621

Posted by CmdrTaco
from the to-busy-to-build-your-own dept.
An anonymous reader writes "Currently, I'm running an old 4u Linux server for my private backup and storage needs. I could add new drives, but it's just way too bulky (and only IDE). For the sake of size and power efficiency I think about replacing it with a NAS solution, but cannot decide which one to get. The only requirements I have are capacity (>1.5TB) and RAID5. Samba/FTP/USB is enough. Since manufacturers always claim their system to be the best, I'd like to hear some suggestions from you Slashdot readers."

Persistent Terminals For a Dedicated Computing Box? 288

Posted by Soulskill
from the persistence-pays-off dept.
Theovon writes "I just built a high-end quad-core Linux PC dedicated to number-crunching. Its job is to sit in the corner with no keyboard, mouse, or monitor and do nothing but compute (genetic algorithms, neural nets, and other research). My issue is that I would like to have something like persistent terminal sessions. I've considered using Xvnc in a completely headless configuration (some useful documentation here, here, here, and here). However, for most of my uses, this is overkill. Total waste of memory and compute time. However, if I decided to run FPGA synthesis software under WINE, this will become necessary. Unfortunately, I can't quite figure out how to get persistent X11 session where I'm automatically logged in (or can stay logged in), while maintaining enough security that I don't mind opening the VNC port on my firewall (with a changed port number, of course). I'm also going to check out Xpra, but I've only just heard about it and have no idea how to use it. For the short term, the main need is just terminals. I'd like to be able to connect and see how something is going. One option is to just run things with nohup and then login and 'tail -f' to watch the log file. I've also heard of screen, but I'm unfamiliar with it. Have other Slashdot users encountered this situation? What did you use? What's hard, what's easy, and what works well?"

What To Do With a Hundred Hard Drives? 487

Posted by Soulskill
from the build-a-hard-drive-cannon dept.
Makoto916 writes "In five years with my current employer as the IT administrator, I've amassed a sizable cabinet of discarded hard drives; just shy of 100, in fact. All of the drives range in size from 20GB up to 300GB. They've all been stored in anti-stat bags, and spot checks of even the oldest ones show that most of them still work. Individually, they're mostly useless for our line of work, which is digital video production. However, the collective storage potential is quite significant. They are of varying size and speed, but the one commonality is they're all IDE. What is the best way to approach connecting all of these devices and realizing their storage potential? On a budget, of course. Now, I'd never use such an array for critical data storage, but it certainly would be useful as a massive backup array to our existing SAN that does store critical data. I have several spare and functioning PCs, but not nearly enough to utilize their internal IDE controllers; even with multiple add-in controllers, it still wouldn't be enough. Not to mention the nightmare of managing a bunch of independent PCs. I've looked into ATA Over Ethernet and there's a lot of potential there, but current 15 to 20 bay AoE cabinets are expensive, and single device enclosures are so rare that they're also expensive. Are there any hardware hackers out there who have crafted their own home-brew AoE systems? Could they scale to 100 drives? Is there a better way?"

Are Academic Journals Obsolete? 317

Posted by timothy
from the all-the-cool-kids dept.
Writing "Surely there is a better way," eggy78 asks "With the ability to get information anywhere in the world in seconds, and the virtually immediate obsolescence of any printed work, why are journals such an important part of academic research? Many of these journals take two or more years to print an article after it has been submitted, and the information is very difficult (or expensive) to obtain. Does this hinder technological advancement? There are certainly other venues for peer review, so why journals? What do they offer our society? Are they just a way to evaluate the productivity of professors?"
