Tamás Szelei's questions

I would like to create a short clip of me playing Minecraft, an OpenGL game. The usual screencast recorders do not properly record OpenGL.

What kind of software is available for this purpose?

My experience with the software in the similar (but no longer duplicate) question:

1. kazam: very low framerate despite setting to 60 FPS, no sound, unity menubar constantly flashing through the fullscreen window.
2. RecordMyDesktop: max framerate setting is 50 FPS, but the video becomes extremely fast if not using the default 15 FPS.
3. xvidcap: not available on 12.04
4. tibesti: not available on 12.04
5. wink: does not run
6. ffmpeg: very low quality video and no sound with the recommended settings, might be tunable though (no gui unfortunately).
7. kdenlive: uses recordmydesktop, and the recorded clip becomes corrupted
8. aconv: video sped up, often broken image, no sound

The libboost-dev package in the repos is an older one and I would like to use the newest release. I'm OK with installing from source, but am a little confused by the instructions on the site. It instructs to run

./b2 install --prefix=PREFIX

where PREFIX is a directory where you want Boost.Build to be installed.

What should PREFIX be set to so that the libraries and headers are available for the compilers to find without specifying custom paths?

Although my ethernet card worked, I had very bad latency and speed. I looked up the hardware and I found a driver. Having run its autorun.sh script makes the hardware work correctly. It loads the module by calling modprobe. However, I have to do this after every boot. How can I permanently install this module?

I read many places that the rule of thumb for swap space is to double the amount of physical RAM. However, 32 GB does seem a LOT. Do I need that much? Do I need it at all with this high amount of physical RAM?

I'm building a new configuration and intend to buy an SSD with it. I recall that the first SSDs were problematic in Linux for some reason (maybe lack of TRIM support?).

Is there something to specifically avoid in today's SSDs? Or is it a safe bet to buy any?

I have 4.5.2 installed from the Ubuntu official repositories. I would like to install 4.6 as well to try out the C++0x features it brings.

How can I do this without breaking my system? I'm fine with the newer being default, but also want to keep the older version.

From a developer's perspective. Should I use a text-based config in /etc or in $HOME? Or something else?

I started a hobby project and figured that if there were some reasonably reachable criteria for this, I might as well work in that direction. Tried asking on #ubuntu-app-devel, but the channel seems kinda dead.

I want to save the list of packages that have installed. I figured it might be the best to list all and diff it with the default set.

Edit: Clarification: I don't want to get the list of installed packages that are installed at the moment. Rather I want to get the list of packages that I added since the default install.
