comment How do I tell if my Memory is ECC or Non-ECC?
@Hennes: You can have 10, but 9 is far more common. The memory is typically split into chunks of 72-bits (8 bits read at once from each of 9 data-chips), with 64-bits of data + 8-bits of error-correction in each chunk. See here for more technical info.

comment Can a file be maliciously changed in a way that maintains its original SHA-1 Hash?
The question is, why would you want to use a hash that has any known vulnerabilities, when there are alternatives that are just as fast, easy to use, and widely available that don't (eg. SHA-256)? Additionally, there's a reason cryptographers declare a hash insecure after only one vulnerability is found: history has shown that when one is found, others quickly follow. The famous Bruce Schneier quote is "Attacks always get better, they never get worse"

comment Can a file be maliciously changed in a way that maintains its original SHA-1 Hash?
-1 everything in this post is completely made up. Length-extension attacks do not "maintain the same hash" (the hash just changes in a known way). Also, there's no reason a virus would have to remove "the less-used code" (how would it even determine what that is?). And what do jpegs have to do with anything!?

comment How to make Shift, Ctrl and Alt toggle like Caps lock
This feature is the bane of every video game player who hits 'shift' 5 times for whatever reason while playing and is immediately minimized to the desktop, usually followed by their in-game death.

comment Why is a 7zipped file larger than the raw file?
@Mehrdad: "Is there any compression algorithm (however poor) that does not increase the length of any input?" - The answer is no. There are 2^(n+1)-1 possible messages of size n-bits or less. Our algorithm must map each one of these to a unique output. If even one of these gets mapped to a value with fewer bits, another value must necessarily get mapped to one with more.

comment How does Netflix know my password?
@kasperd: Collisions can be generated on-demand for MD5‌​, making it completely insecure. Note that this is not the same vulnerability as "finding out your password". Your argument is a straw man; please stop spreading misinformation.

comment My motherboard doesn't support AHCI, is IDE mode + SATA 2 much slower for new SDD/HDD/SSHD?
If you do not disable read/write caching, you are not testing AHCI, you're testing your OS's proficiency at caching.

comment How does Netflix know my password?
You guys are using two different definitions of the term "one-way". There's the mathematical definition which simply means "not injective," and then there's the computer science definition which means "cryptographically secure." When discussing cryptographic hash functions we always use the second definition, so the statement "MD5 is no longer one-way" is correct.

Did you disable read/write caching when doing these tests? Otherwise you are measuring the completely wrong thing.

comment Will my “6-core CPU” motherboard support an 8-core CPU?
Er, I thought the whole point of the AM3+ socket-type was that it was backwards compatible with AM3 sockets, but also forward-compatible with the upcoming AM4 socket? At least, that's how it worked with AM2/AM2+.. But in either case, while this does solve my problem, it does not answer the question in the title, for anyone who finds this page via google, so I cannot mark it as correct.

comment Can my landlord access my personal network because he controls the upstream connection?
@Jason Anyone who can follow simple instructions can install custom firmware on home/soho routers. They could also use a linux box with two ethernet ports.

What tool did you use to determine that VS 2010 is the culprit? @JRobert's link contains dozens of programs..

comment How can I tell which laptop touch-screens work well with a stylus (for drawing/taking notes)?
@DaveRook according to meta.superuser.com/a/5545/23668 this sort of question is on-topic: "However, a question that allows for a learning opportunity and that can be applied to various situations, of the form "how can I determine [for myself] which foo can do bar" has potential to be valuable."

I'm not sure why the close-vote; if you read past the first sentence, you'll see this isn't a shopping recommendation, it's about the different types of touch-screens

comment How can I view HD videos without stuttering on PS3 Media server?
Nowadays "Video quality" has been renamed "transcoder quality," and is a dropdown. There's an option for "Wireless," but unfortunately that doesn't work for me - I need to set it to "Low quality (Slow CPU)" to get no stuttering on wireless for some videos (my CPU is blazing fast, the only issue is the connection). Despite the name, though, it doesn't actually look that bad.

comment How can I enter Unicode characters (e.g. ♥♦♣♠) when logging into Windows?
FYI alt-codes enter characters from your current codepage, not unicode. You need to set a flag in the registry to use unicode alt-codes.

comment What stops an internet router from sniffing my traffic?
@FrankThomas: The US government uses one-time pads for its most secure transmissions. They transfer truck-loads of tapes with large random keys on them by armed-guard, or so the story goes.

comment Disable “Do you want to change the color scheme to improve performance?” warning
"I never assumed the message can be turned off and I don't see how that could be considered a benefit." - Because this message pops up often when playing video games, pulling me out of the game (which sometimes isn't paused) just to disable this message once again. I don't care that my system is using all its GPU ram (in fact, that's a good thing). I don't care if Windows Aero runs slow while I'm in my game, as long as the game continues to run fine - which it always does. I just want this message to not disrupt my gaming.
