Improving the Beaglebone Board with Embedded Ubuntu, Enhanced GPMC Driver and Python for Communication and Graphical Prototypes
Final Master Thesis Improving the BeagleBone board with embedded Ubuntu, enhanced GPMC driver and Python for communication and graphical prototypes By RUBÉN GONZÁLEZ MUÑOZ Directed by MANUEL M. DOMINGUEZ PUMAR FINAL MASTER THESIS 30 ECTS, JULY 2015, ELECTRICAL AND ELECTRONICS ENGINEERING Abstract Abstract BeagleBone is a low price, small size Linux embedded microcomputer with a full set of I/O pins and processing power for real-time applications, also expandable with cape pluggable boards. The current work has been focused on improving the performance of this board. In this case, the BeagleBone comes with a pre-installed Angstrom OS and with a cape board using a particular software “overlay” and applications. Due to a lack of support, this pre-installed OS has been replaced by Ubuntu. As a consequence, the cape software and applications need to be adapted. Another necessity that emerges from the stated changes is to improve the communications through a GPMC interface. The depicted driver has been built for the new system as well as synchronous variants, also developed and tested. Finally, a set of applications in Python using the cape functionalities has been developed. Some extra graphical features have been included as example.

Figure 1. Graphical representation of sound • We are used to editing sound graphically. • But for many operations, we do not actually need to see the waveform! 4.1 Potential applications • • • • • • • • • • • • • • • • 1 of 11 21m.380 · Workshop: Command-line sound editing · Wed, 12/7/2016 4.2 Advantages • No visual belief system (what you hear is what you hear) • Faster (no need to load guis or waveforms) • Efficient batch-processing (applying editing sequence to multiple files) • Self-documenting (simply save an editing sequence to a script) • Imaginative (might give you different ideas of what’s possible) • Way cooler (let’s face it) © 4.3 Software packages On Debian-based gnu/Linux systems (e.g., Ubuntu), install any of the below packages via apt, e.g., sudo apt-get install mplayer.

Practical Debian Administration
Practical Debian Administration Alexander Zangerl [email protected] Abstract Debian GNU/Linux offers a very rich and well-designed environment to a system administrator. This talk is about the most important tasks you will face on any Debian box, and how to deal with them most efficiently; I will also present some of the less well-known (but in my opinion still quite interesting) Debian-specific tools and approaches that can make administrating a Debian system very pleasant. 1 Debian in a Nutshell Debian is a free, volunteer-produced Linux/Unix Operating System Distribution. As I pointed out in some detail in a previous paper[1], Debian is very well suited for experienced Unix users as well as large scale environments for a variety of reasons; we might very well call Debian \The Distribution for Sysadmins by Sysadmins". The biggest difference[5] between Debian and other operating system distributions is that Debian uses a very extensive policy and stringent quality assurance processes which produce one well integrated operating system from thousands of disjunct little pieces of software. Other distributions recently have adopted apt as Debian's \killer app" as they perceive it, but in fact the real killer apps are the policy, the bug handling rules and methods, the security team and all the other codified consistency and quality measures. While people are using \apt-get into it!" as slogan for Debian, I'd rather something like \Policy makes Perfect". All that flexibility and the project size come at a price[6], too, but mostly that price is paid by the developers. -

Game Data Packager
game-data-packager A data-driven, cross-distribution installer for commercial game assets. Background ● Many old games were either re-released as free software or reverse engineered ➢ But most times it's only the game engine, not the data ● There well exists free alternative data sets for some games – FreeDoom (Doom I & II) – OpenTTD (Transport Tycoon Deluxe) – Lgeneral (Panzer General) ● Other engines, while being free software; are useless on their own, so they end up in alternate repositories: - Debian: contrib, or non-free if there's a non-commercial clause - Fedora: these goes in alternative RPMFusion repository Acquiring non-free data ● Most shareware games can only be distributed as a copy of the original archive; commercial game assets cannot be distributed at all. ● game-data-packager existed in Debian since 2005 as a tool that creates .deb packages for local use. ● Other distributions are providing similar scripts, that also involves wget, md5sum, unzip,… … and a lot of duplicated work. https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=heretic1-wad ● Fedora & Mageia are using autodownloader that saves data in /home/. ● Each game engine has detailed instructions to follow by hand. Happy new year 2015 ● A new data-driven engine was committed to git around 2015/01/01 : – engine is written in Python3 – per-game definitions are stored in human-writable machine-readable YAML files. – a plug-in system can handle individual game quirks ● An authoring tool is then added, all the existing shell scripts got rewritten pretty fast. « -

SoXI(1) Sound eXchange SoXI(1) NAME SoXI − Sound eXchange Information, display sound file metadata SYNOPSIS soxi [−V[level]] [−T][−t|−r|−c|−s|−d|−D|−b|−B|−p|−e|−a] infile1 ... DESCRIPTION Displays information from the header of a givenaudio file or files. Supported audio file types are listed and described in soxformat(7). Note however, that soxi is intended for use only with audio files with a self- describing header. By default, as much information as is available is shown. An option may be giventoselect just a single piece of information (perhaps for use in a script or batch-file). OPTIONS −V Set verbosity.See sox(1) for details. −T Used with multiple files; changes the behaviour of −s, −d and −D to display the total across all givenfiles. Note that when used with −s with files with different sampling rates, this is of ques- tionable value. −t Showdetected file-type. −r Showsample-rate. −c Shownumber of channels. −s Shownumber of samples (0 if unavailable). −d Showduration in hours, minutes and seconds (0 if unavailable). Equivalent to number of samples divided by the sample-rate. −D Showduration in seconds (0 if unavailable). −b Shownumber of bits per sample (0 if not applicable). −B Showthe bitrate averaged overthe whole file (0 if unavailable). −p Showestimated sample precision in bits. −e Showthe name of the audio encoding. −a Showfile comments (annotations) if available. BUGS Please report anybugs found in this version of SoX to the mailing list ([email protected]).
