comment Is email encryption practical enough?
@Mnementh: If you are going to have personal meetings, you might as well just use them for key exchange. No need for a keyserver, then. Keyservers are nice, but you end up having to trust something else, somehow, in order to use them. That's where I get nervous.

Actually, secure transmission isn't required, just initial secure key exchange. If you can exchange keys securely, AND we assume that the encryption algorithm has exploitable flaws, then it doesn't matter if the intervening networks are secure or not - only the recipient will be able to decrypt the message.

Signing e-mail is not the same as encrypting it. Signing solves the identity problem (who sent it), but it doesn't keep the contents secret.

comment How to test your backups against medium degeneration?
SMART results may not tell you as much as you'd like. Google labs did some testing - labs.google.com/papers/disk_failures.pdf and found that they got lots of failures with no SMART warning at all.

comment How to force Windows to rename a file with a special character?
May I ask how you got to this state? Windows generally won't let you do this.

comment Why can I not combine two partitions into one from Disk Management?
Yuk. I just checked the Wikipedia entry. Apparently Symantec hasn't updated the thing in years, and it had crash problems with Vista formatted partitions. No mention of Win 7, but I'd bet that it's no good. Too bad, I bought a copy from PowerQuest years ago and it was rock solid at the time. Sad to see Symantec letting it go to bit rot.

Well, now we know. He needs to backup first anyway, but it's good to know. Can the latest PM work with Win 7 drives?

comment Why can I not combine two partitions into one from Disk Management?
Well, you don't really have any other options. I believe that there is no free tool that will combine live filesystems and leave the contents intact. I'm not even sure Partition Magic (a non-free tool) can do that. Combining two filesystems without losing any data along the way is pretty difficult to get exactly right. Even if there were a free solution, you'd need to back everything up first, because any bug could destroy all your data.

comment Makeshift multiple monitor support?
SLI is for two graphics cards to communicate. If you are doing things that can be split among GPUs, SLI can help make that possible.

Yup, you're right. And I see that you've already found it.

comment Can I upgrade my wireless network reach by switching the router from 802.11g to 802.11n without upgrading all the clients?
Yes. And I should have seen that problem when I typed it.

comment USB to Serial adapter/cable Windows/Mac/Linux
I've used FTDI based USB-to-Serial on Linux several times and not had a problem. In fact, I've had a lot more trouble with on-board serial ports, than with the FTDI ones.

comment Create Factory Restore Disk for Acer Aspire D250
I'm rather fond of linux (I use the System Rescue CD, which can be setup to boot from a USB stick). I then use 'dd' to create a complete image of the working HD.

comment Thinkpad T60: VGA output is tinted yellow (but not DVI output)
Unlike DVI, VGA is quite analog, so if a pin is making poor connection (either because the pin in the connector isn't in good shape, or because the connection to the motherboard is damaged), you'll get bad signals on that pin, which will screw up the output visuals. Since you've tried other cables and monitors, it's back to the service guys I'm afraid.

comment Video encoding for archival
Agreed, I was more considering format than lifetime of the media. I don't know of any media currently available that I'd trust for more than a few years. HDs might do OK sitting on the shelf, but they might not. CDs are too damn small. SSD drives using USB might not be bad, if you thing the flash memories they are based on will last.

comment Is 4GB Ram sufficient for a 64 bit OS
@freedom_is_chaos - it's not quite that simple. PAE allows the KERNEL to access larger amounts of memory. It's somewhat limited in actual use because there are sometimes issues with device drivers (not everyone tests properly for these conditions), and of course no application can get more than it's normal 2 or 3 gigs of memory. But it's still sometimes useful, especially on desktop systems. @edgarholleis - Explaining what's wrong would have been more helpful.

comment Microsoft Office alternative for Windows?
I'm fascinated by the prices quoted in various answers for student editions. MS has made their pricing structure so complicated, no one can figure out what anything costs...

comment How does an iPhone know which mp3s are podcasts?
Yes, iTunes 'knows' they are podcasts because of how it got them. This is a SERIOUSLY annoying mis-feature that iTunes has had for years. There are lots of little things that iTunes will or won't do with something that it 'knows' is a podcast (like auto-load it onto a shuffle). Good luck getting around this by any means other than using iTunes. Unfortunately, you've run into one of the many areas where Apple's approach to things makes it hard on the end user who doesn't fit the expectations Apple has.

comment converting mp3 to 3gp
At the very least, choose a higher bitrate on the target format than the mp3 was. That will help minimize the overall quality loss from transcoding.
