Getting Synaptics trackpad to send actual scroll-wheel events
I have a laptop (a Samsung Series 9) with a Synaptics trackpad, and I have Windows XP on it. One of the nice features of this trackpad is that it allows you to scroll by placing two fingers on the trackpad and then dragging them up or down.

Where does the file owner on Windows matter, seeing that there are ACLs?
Coming from a Linux background, I'm used to a file having an owner, and a owning group. Access permissions can be set separately for owner, group, and others, and that's it. Now on (NT-based) Windows, it's a bit different, because Windows uses ACLs. That means instead of having three lists of permi…

Possible to rotate video (.MOV/H.264/AVC) losslessly?
The iPhone (3GS, 4, 4S, etc) often records video upside-down but then includes metadata about the rotation inside the MOV container. However, many applications (XBMC, VLC, Windows Media Player) do not understand this rotation metadata and so the videos play upside-down. Is it possible to permanentl…
Does GNU/Linux counts processes and threads together when I limit their number?
I want to limit the number of processes per user on my machine, with and the nproc value. I have read here that Linux dosen't distinguish between processes and threads?

Stop automatic video play in Firefox
Is there a way to let embedded videos (primarily Flash, but I'd prefer something that will also work with HTML5 video) automatically background load, but not start playing until explicitly started?

Kill process by name and owner?
Before I look into reinventing the wheel and roll my own, is anyone aware of an application/utility that allows me to kill processes, filtering by both process name and process owner?

What is the point to 120Hz in 2D mode?
I’ve been searching the Internet for advice on my next PC/console monitor purchase and came across a good deal on the LG D2342P-PN. It’s an LED monitor with all three connectors I want, and even 3D mode at 120Hz—which I didn’t want but why not have? Then, I read some reviews of it and the biggest s…

I open a big file with this command: less +G /var/log/blah/file.log Now when I find the desired info I'd like to know its exact offset in this file, so later I can open that file again and return to that exact place.

How is load average calculated on osx? It seems too high - and how do I analyze it?
An advanced question: I think my load averages are too high as compared to a linux system. I have around 0.40 1min with basically no cpu use (0-1%) and even if this is spread out over 4 cores it still equals roughly 0.10 = 10% cpu use which isn't correct. I've now learned that load average takes no…
