comment How does Netflix know my password?
@kasperd Most people don't have strong 20+ character passwords and use the same password in several different places, which is why we need those slow password hashing functions in the general case. If everyone had a strong password and never reused the same one on any two sites you could even argue you don't need a salt at all. But that's not the case in the real world, so almost any real life system is going to have to cater to that majority of users who "cannot choose good passwords". Therefore the use of debating MD5+salt password hashing systems is questionable (or an academic exercise).

comment How does Netflix know my password?
I have to downvote just for the MD5 example, however good the rest of the answer may be. This is just not something you want to read in 2014 (soon to be 2015). It was never a good idea to use raw MD5 (even with a salt) to store passwords, and most people realized that over the course of the last 10 years. -1

comment Bash- How to make a Linux script file human unreadable?
Maybe he means those installer scripts that just contain a massive embedded binary blob and a couple lines of actual script to dump it to a file and execute it? Just a thought.

comment Why half of my RAM of 8GB is missing?
@Boris_yo Why don't you get a standard 500GB or 1TB HDD to store all the stuff that doesn't need to go on the SSD? It's not healthy for the SSD to be near full anyway due to how TRIM works, and I'm pretty sure you can move the page file to another location (like an HDD) as needed.

comment Minimum standalone graphics card requirements for dual monitor display
If you're not going to be using the graphics card either way then there is no noise to worry about. I just turned my GPU fan to 20% (the minimum possible on mine) and I can't hear a thing. A passive GPU would make zero noise. Are you sure integrated graphics cards don't support dual monitors, though?

comment What does “File not found” mean on a web page?
I'm talking about your general statement and analogy to the stranger's house. It's completely wrong. How and where content is served is up to the configuration of the web server and the website, there is no fundamental rule that URL's need to look like a file path when serving a file. The analogy fails in that you're asking stranger for /framework/images/icons/png/, whatever that may be, and it knows - or is supposed to know - what to do.

comment What does “File not found” mean on a web page?
You may or may not be right in this particular case, but in general that is patently untrue. The web server gets the URL you sent (here /framework/images/icons/png/) and is then free to serve whatever content it wants. There doesn't have to be a file name and extension at the end of the URL, it just often is the case as it reflects the file hierarchy of the website. Similarly, you can be served a .png from an URL that ends in .gif and so on.

comment My colleague often shuts down my machine through the LAN - how do I prevent it?
Perhaps you could ask him to stop shutting down your computer remotely as well? It's a waste of company time and resources.

comment What PPI must be used before the human eye can't distinguish each pixel
@Noodlemanny All good, his answer is more "official", I concur. I just like trying to derive things myself and then checking if it agrees with existing results (in this case they did).

comment What is the danger of inserting and browsing an untrusted USB drive?
Haha, I saw one of these at school once. Some dude would plug it into computers while we were using them and the mouse would start doing things of its own accord (someone was remote-controlling the device from across the room).

comment Is there such a thing as an “HDR monitor”?
"monitors cannot represent big exposure differences, so there are no HDR monitor" - why not? Is this a technological issue (not enough power for the monitor to suitably represent a wide dynamic range) or something else? Are there "medium dynamic range" monitors which are better than LDR while not still capable as displaying the entire dynamic range visible to humans, and do they look natural?

comment Does Chrome's Download Manager resume downloads if the connection is lost or closed?
I did the same as Sathya (except I didn't switch off my wifi.. if you get my drift) and Chrome was unable to resume the download, simply marking it as complete with no option to resume. Sorry.
