+1: WinSCP is awesome.

comment Program that does a screen print every 15 minutes and saves it to a file
Yea, and a lot of it will install itself, given the opportunity.

@CheesePls: I love SCP partly because it supports the recursive flag that lets you move subdirectories without scripting. If the server you're copying to allows ssh, I'd recommend giving it a try.

comment My system show extremely hot processor temperature
+1: Misapplied thermal paste is a very common cause of this sort of behaviour. You should have a very very very thin layer...It's only there to make sure there is no air between the processor and the heatsink.

comment Where does power consumption go in a computer?
Heat energy is almost always a waste product: if we could move electrons around inside a CPU without creating heat, we'd do it in a second.

comment Is zip's encryption really bad?
@Akira: Okay,. My point is that user-generated passphrases are weaker and less reliable then pre-generated keys, and I think that, even if you stipulate a length, the social engineering angle is going to be much more prevalent (people tend to write down long keys). Also, I think that the potential for weak passwords builds a false sense of security (i.e.the data are encrypted, but the password is vulnerable to a weak dictionary attack). In a nutshell: users don't have as much input in asymmetric systems, and I think that's a good thing.

@Akira: What's your point? Do you HAVE a point? The only thing I've said is that there are problems with symmetric key encryption, which you've never refuted, despite all the tangents you keep jumping on to. If you actually have a meaningful point, by all means, continue.

comment Is zip's encryption really bad?
@Akira: That's why the key-sharing problem is solvable via public-key encryption, because it doesn't matter who can ENCRYPT traffic, but only in who can DECRYPT traffic. The same is NOT true for symmetric key encryption which is why its inherently a weaker system: since there is only one key, key transfer is extremely important, and that's the weakest part of the system.

@Akira: But that's not how asymmetric key crypto even WORKS! The private key is encrypted, but that is never shared! It's encrypted so that, if someone breaks into your machine, they have to do a little more work to get your private key. The public key is the shared key, and, since the public key cannot DECRYPT anything, it's not a problem. To go back to the house argument, there is a key that can unlock the door and there is a key that can lock the door. You protect the key that can UNLOCK it, but the key that LOCKS it, you leave on a hook right by the door.

@akira: You can quote the gpg manual all you like, but that doesn't change the fact that the encryption is done via asymmetric keys. The symmetric part only applies to encrypting the private key for storage. If I locked my house with a key, and then stored the key in a combination box that was stored in a secure location, by your logic, my house would be locked with a combination lock. Encrypting the private key is in no way required for asymmetric key encryption.

@akira: You're not even addressing what I'm talking about. Onetime pads are the definition of problematic: hand generated, hand transferred. Symmetric key encryption is problematic because the key generation is left in the hands of the enduser (when they choose their passphrase or whatever), and that is a massive problem.

comment Why is network utilization so low
+1: Yep, yep. If your network adapter is gigabit, and you're connecting out through a 10 megabit high speed internet line, that's 1%. If you're not sharing a massive amount of data across a LAN, then your max is always going to be capped by your maximum upload/download speed.

comment How to make one CPU to be used simulataneously be three different users
+1: Best idea in this situation: program in shifts, or program in groups. Splitting 1 laptop 3 ways leaves 3 people without enough computer to get their work done.

comment Setting default path in Unix
As an additional wacky check, do which valgrind and make sure that it's not trying to execute one in another directory.

comment What kind of eye wear can I use to protect my eyes from being irritated from staring at a screen all day?
Fricking no-glare coating doesn't do much more than make the glasses impossible to clean.

comment Suggestions for Backup solution
@shiki: I'm not a fan of Robocopy. Somehow it made it into production at work, and it's just not suited for that sort of abuse.

comment 4 GB DDR2 vs 2 GB DDR 3
+1: In the long run you're going to see more of a benefit with fewer page faults than with faster page faults.

comment How do I kill a process that keeps respawning?
+1: Reformatting is the best option, as far as security and efficiency go. You can't ever be sure of a machine after its been infected. I work for a big corporation, and we re-image infected machines whenever we find them. We have a godawful huge amount of expensive antivirus software, and we STILL do it that way.
