comment Change framerate on MKV container
Wouldn't it be easier to change the subtitles? If you speed up the movie from 25 to 23.98, you'll also have to pitch up the audio and it'll look/sound unnatural. Also, you'd have to recompress the bitstreams.

comment Is there a way to check if driver si working correctly in VM
Ok, good then! But in the future, I would encourage you to try to rephrase your question by describing what exactly the situation is now, and what information you want. It's just a little unclear at the moment.

comment Is there a way to check if driver si working correctly in VM
I don't understand this question. A VM has no access to the underlying hardware; therefore you cannot check whether a driver works. You can check only in the host OS. And if you have no OS installed at all, there is no driver.

comment Streaming mp4 with ffmpeg
Actually I was a little inaccurate in the above comment. Indeed it makes sense that you can't "stream" an MP4 because it contains global metadata in the file header, which makes random stream access impossible. You might want to look into setting up HTTP Live Streaming (which is Apple's own technology), which uses MPEG-2 Transport Streams and transmits the video in segments.

comment How to create a table for my website which changes daily?
@davidgo We really shouldn't encourage people to post off topic questions here by answering them. (Why bother if it's off topic when you get an answer anyway, right? This has been discussed often.) So please, consider your knowledge about Super User's scope when answering questions, and throwing in a migration vote yourself if warranted.

comment Find if a short MP3 exists in a longer MP3
I don't know exactly. It depends on what scale of time such a hash is computed and how long your cut MP3s are. You'd then have to create overlapping windows of hashes of the source MP3 at intervals of your desired accuracy, I suppose. Then, compare the individual MP3 hashes against the precomputed hashes of the original. This seems like a computational nightmare though. I'm not too much of an expert with this acoustic fingerprinting. A binary search may also be possible, like finding the rough area of the cut MP3 and then narrowing down.

comment Find if a short MP3 exists in a longer MP3
EchoNest on its own can't do that. But that would be a nice project if I had a few days time. It's not so easy since you're dealing with specific time constraints.

Please be more specific by what you mean with "require password". Do you want to be able to login graphically without a password? Login on a (remote) shell? Run sudo without a password?

comment What is the hash algorithm for owncloud passwords
Have you looked into the source code? Or the configuration? github.com/owncloud/core/blob/… Seems a salt is involved, somewhere.
