I'd love to save some power! I have a dual opteron 246 workstation. These CPUs don't support any kind of low power mode. The room gets a few degrees warmer when I run this computer. *Now* tell me how I can save some power while being able to use the workstation. Sleep mode, my ass.. And no, I'm not planning to shell out some $$ to swap the CPUs any time soon:P
they're now owned by the big guys. using them is pretty much pointless ever since google came out with a better algorithm. the big four (google/yahoo/msn/ask) use comparable quality algorithms, everyone else just leeches off them or uses much lower quality algorithms
Thank you for your advice, but I think you're taking it a tad too far. I'm not encrypting child pornography, I'm encrypting my company's sensitive files. In other words, I don't want deniability, I just don't want to be liable if my laptop is stolen or somesuch.
The idea with this key is that a backup is stored in a secure place. If you forget the password or lose the key, a backup key can be used to recover the data. I don't agree with implementation, mind you - the company wants me to store that recovery key with them. I'd much rather store it in a safe deposit box. Maybe that's just me, though...
How about moving the IDF underground? (or rather, below the heat-generating equipment) If you build a small "basement" as a networking closet, you won't need to do all that much to shield it from the heat. just a thought...
Does anyone else think it's about time to make a small satellite with a few "claws" to fly around our existing satellites and replace their various parts? It could probably do repairs to the ISS as well (spacewalks should be for fun, not for work).
one problem is, what if someone turns the computer with crontab shortly after you're dead? Just write up all your instructions (including passwords if you want) in a will. I'm pretty sure you can specify that content meant for different people must be kept confidential from all others.
Not sure if it's obvious to others, but this seems to me like a really good way to kick off medicine in a new direction. Let's say this technique fails to cure cancer - that's not the end of the road, though - someone will surely try it to target nanoparticles elsewhere, like AIDS. I'd invest a lot of money into this venture if I had any:)
I was going to suggest POP3 with leave-mail-on-server + sorting rules: this way works well for me. Also, force thunderbird to BCC your own email on every message you send out - that way the threads of conversation look beautiful AND you get a trail of "sent" emails on all machines you use.
However, if you really want to always have a perfect sync, consider putting the mail folders on a flash drive and using that every time you check your email. That adds some security too, since if the data is not present, it can't really be compromised (of course you should also encrypt the data on flash drive). I checked while migrating from windows to linux - thunderbird uses the same format for mailboxes (you should be able to use it directly)
I agree with you - just look at what happened to Sega Saturn (2-CPU system). In a few years this will all change, however - the functional languages are starting to mature, which means fresh students will be taught to use them. Well, that's the hope, anyway:) The beauty of functional languages is the level of parallelism they allow. The paradigm is that nothing is dependent on state, which means the computation can be performed as a "black box" on an independent CPU/core. It's not a panacea, but it should help a lot.
From the developers perspective, the Microsoft solution cen be the best choice - it allows (or will soon) to write games that are cross-compatible between the console and the PC, thereby minimizing the gaming company's efforts to get into both markets. I think that's a very lucrative incentive. The next generation of MS console will most likely have a motion-sensitive controller as well. They've actually made motion-sensitive products before, so they can easily accomplish and likely top the feat, especially with the advances in technology made so far. I'm sure they already have a prototype already. Their weak point, however, is lack of backward compatibility - hopefully that will change next time.
I didn't know that there are twice as many registers in 64bit version. Of course that's only effective for applications compiled to run natively in 64 bit, not 32 bit guest applications... but I see your point.
Your processing power won't improve at all by switching to x64. The only improvement is that you will be able to address more RAM and HD space, nothing else. In fact, you will even lose out - 64 bit systems waste more memory than 32 bit systems. That's primarily because the 32-bit structures take up 64 bits on 64 bit system, while not carrying any more data. And all the pointers are suddenly 64 bit in length, etc. In other words, it's worth switching only if you have and plan to use a reasonably larger amount of RAM/HD space than the 32 bit max limit. (in other words, if you want to switch to use 5gb, i'd recommend sticking with 32 bit system, but for 6gb or 8gb the pros start outweighing the cons)
second that. I was about to send you an email asking the same thing: what are the start-up and operating costs? (start-up would be cost of the laser device, and operating - your electrical bill)
In terms of fuel, you're probably right. However, I'm sure there's a lot more to it than just fuel. What about supplies, for instance? Let's say you need 1 ton of supplies - but the shuttle will only take 200 kilos away from earth. Either you need to build a bigger rocket, one that can take up 1 ton, or you can stockpile the stuff somewhere. Moon makes sense because it has lower gravity (which means the craft that could take up 200 kilos might take 1 ton up from the moon). You don't want to fill ISS with supplies for something like this. Plus, humans are used to building structures under gravity's effect - which means it should be much easier to build a port on the moon than in space. That is not to say that the solution sounds feasible right now.. Not only there's a matter of basic supplies, but also there are problems like radiation and meteorites - which are not so easily solved.
Feh, with so many problems we'll get there by walking first.

Fedora Linux

I've started using Ubuntu as my first Linux - I loved the kind of support I was able to get at Ubuntu forums (fast responses, nobody being condescending to a n00b like me...) - but for me the dealbreaker was that the packages were not up-to-date for a long time. It's true, the working packages should only be updated after they've been through a lot of testing - but the problem is, not all software works correctly in the old versions.. I'm using Fedora now - grinding my teeth whenever a problem occurs - but using it nonetheless. Anyway, it would've been perfect if Fedora came with Ubuntu-level support... oh well, I can dream:P
Or maybe it doesn't have to be a dream.. I've seen Fedora-specific questions being answered on Ubuntu forums - maybe there's still hope
actually, google sometimes changes the result URLs to redirects like "google.com/redir?url=http://example.com" (not just like that, but you get the idea). then their server is set up to send an HTTP redirect message to your browser whenever you click on that link - you get to the page and don't even notice that your click was logged
yahoo does this all the time (and for whatever reason they redirect between their internal sites multiple times - a redirect inside another redirect.. *shrug*)
The best implementation of "protection" I've seen in schools was re-imaging the OS automatically over the network on every bootup. The students can do WHATEVER they want, (giving them the local admin access becomes safer, though still not recommended) - at logout the computer reboots and it is once again clean for the next user. HD space is cheaper now, so you might be able to get away with a hidden partition for re-imaging. Problem is, what if they modify the hidden partition with something malicious? As for speed, the implementation I've seen took an average time to boot up; if one wasn't looking at the screen they'd think it was regular windows installation. I'm guessing it wasn't re-imaging the WHOLE partition, just the parts that have been changed. Don't remember the name of the software they used, though:(

Thanks for staying on topic and answering my question in great detail.

Exactly right. That's why I was looking into these keys in the first place.
The idea with this key is that a backup is stored in a secure place. If you forget the password or lose the key, a backup key can be used to recover the data.
I don't agree with implementation, mind you - the company wants me to store that recovery key with them. I'd much rather store it in a safe deposit box. Maybe that's just me, though...
Let me guess, they also improved its hardware specs by upgrading to cell processor and a blu-ray drive...

Come to me, son of Jor-El! KNEEL before ZOD!!
Okay, I got it out of my system now...
ZOD!!!!!
..be careful asking for pointers
I'm surprised they didn't mention this old gag

If it cost $20 instead of $100, I would buy one just to display those three buttons on my desktop
