Mechanical Engineering Useful Software in Linux
So, as usual, I've no wrote in this space for a long time, but today, as my daughter sleeps like a baby (10 months :P), I've got the time for some writings.. So since my last post, I've acquired a new 13" laptop to replace the good old asus eee 701, I needed a small, fast and good pc for some of my engineering work. Just in short lines the PC is an Acer Travelmate 8371, and Linux Mint Debian Edition runs very smooth.... only one thing does not work at all, and that is the fingerprint reader, which I don't care at all.. One of the most important things for me in laptops is battery (6 hours) and suspend (all ACPI events works out of the box. Even the intel wireless card work without problems...So I'm very pleased with this little and robust machine... So, back on the post title....
QEMU is a fairly complete x86 emulator that lets you run one operating system under another. Currently it is best supported under Linux where it can host numerous other OSes . This guide looks are running Windows XP under QEMU on Debian Linux. Note: although Debian is free you must have a license for the copy of Windows XP you will be running. QEMU uses a large file rather than a real partition to run the guest perating system.

If you want to reduce PDF file size using command line you can use ghostscript.Ghostscript is used for PostScript/PDF preview and printing. Usually as a back-end to a program such as ghostview, it can display PostScript and PDF documents in an X11 environment. Furthermore, it can render PostScript and PDF files as graphics to be printed on non-PostScript printers.

Second release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3 released Another iteration of release candidates for Python 2.6.8 , 2.7.3 , 3.1.5 , and 3.2.3 have been released for testing. They include several security fixes. EuroPython 2012 will be in Florence, Italy, July 2nd-8th. The Call for Proposals is open until March, 18th. Sponsorship packages are available, too!

Caveat: The material in this topic uses the os.fork() function which is not available under Microsoft Windows. (One reason is that Windows, compared to Unix, is very slow to create new processes so that in practice you would never use fork() even if you could! There is another solution to this problem - threading - that works on both Unix and Windows which we will cover in a later topic.) If you are using Windows I recommend that you read the concept sections at the top because the principles will be used in the next topic.
wxPython is not part of the standard Python distribution and has to be downloaded and installed separately. It's best to tell the user that wxPython is required but has not been found (hence the try/except ImportError). Keeping track of parents is usefull when we have to show/hide a group of widgets, repaint them on screen or simply destroy them when application exits. It's usually best to have the portion of code which creates all the GUI elements (button, text fields...) separate from the logic of the program.

Note: Xorg -configure may not always work, as indicated in Xorg(1). In any case, if you are using Squeeze, read on, as you no longer need a full xorg.conf. You should use a file in /etc/X11/xorg.conf.d , e.g.
This tutorial assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction . . . all the while sneaking in little nuggets of UNIX ® wisdom and lore . It serves as a textbook, a manual for self-study, and a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts .

7.8. Using MEncoder to create VCD/SVCD/DVD-compliant files
7.8.1. Format Constraints MEncoder is capable of creating VCD, SCVD and DVD format MPEG files using the libavcodec library. These files can then be used in conjunction with vcdimager or dvdauthor to create discs that will play on a standard set-top player. The DVD, SVCD, and VCD formats are subject to heavy constraints. Only a small selection of encoded picture sizes and aspect ratios are available.
Daniel Davis - Watching videos on the Wii
I looked into the AVI method as I have a 2GB SD card handy. It seems the Wii only supports MJPEG video files which, while compatible with many digital cameras, tend to be very large with a 100MB file giving you just a few minutes of video. You need to have Mencoder installed first (it's part of MPlayer ) and you may need to change the framerate (fps) to 23.97 or similar if the audio is out of sync. Mencoder should accept any video format as input (i.e. FLV, etc.), not just AVI.7.8.1.
