Hacker Public Radio

Please consider recording an episode for Hacker Public Radio. We are a you-contribute podcast. :) Ken requests an episode on Fahrenheit, which really requires discussion of the two temperature systems, and how they are quantified. Terminology Centigrade: old fashioned term for Celsius Kelvin (K): less common measurement of temperature used for Science Thermal Equilibrium: en.wikipedia.org/wiki/Thermodynamic_equilibrium‎ Zeroth Law of Thermodynamics: en.wikipedia.org/wiki/Zeroth_law_of_thermodynamics Absolute zero: en.wikipedia.org/wiki/Absolute_zero My personal preference is Celsius. Less numbers to deal with in everyday use. Really Cold – Temperatures below 0°C Really Hot – Temperatures above 30°C The "American" thinking is temperatures go in 20's, 30's, 40's...ect. more work! Obligatory gun discussion Indirect conversation about PV = nRT formula Correction: the absence of pressure (vacuum) causes water to boil. Celsius and Fahrenheit are "measured" by the states of water boiling/freezing. Celsius freezes at 0° boils at 100° Fahrenheit freezes at 32 boils 212° 1 (K) Kelvin = -273.15°C

In what has become an annual thing, Jezra and NYbill talk about their New Years predictions past and future. Better late then never, I guess...

In episode "Thu 2013-12-19: hpr1404 Editing pre-recorded audio in Audacity" I walked you through editing a podcast, by the magic of editing this is been posted after the other show has aired. The plan here is to get people to share their useful hacks to show how elegent, or in my case ugly, code can be. As Knightwise says "Getting technology to work for you."™ Feel free to share your own hacks with us. http://hackerpublicradio.org/eps.php?id=1404 http://hackerpublicradio.org/eps/hpr1430-downloader.bash.txt #!/bin/bash # Downloads videos from youtube based on selection from http://thebestofyoutube.com # (c) Ken Fallon http://kenfallon.com # Released under the CC-0 maxtodownload=10 savepath="/mnt/media/Videos/tv/youtube/bestofyoutube" savedir="${savepath}/$(date -u +%Y-%m-%d_%H-%M-%SZ_%A)" mkdir -p ${savedir} logfile="${savepath}/downloaded.log" # Gather the list seq 1 ${maxtodownload} | while read videopage; do thisvideolist=$(wget --quiet "http://bestofyoutube.com/index.php?page=${videopage}" -O - | grep 'www.youtube.com/embed/' | sed 's#^.*www.youtube.com/embed/##' | awk -F '"|?'

Do you know the Sanctum games? You should! Listen to Armin from Coffee Stain Studios on todays episode of Hacker Public Radio! "We're actually working on Linux support. *pause* I don't know if I'm supposed to say that."-- Armin Coffee Stain Studios In 2010 a few students from the University of Skövde created the Indie game developing company "Coffee Stain Studios". In 2011 they released the game "Sanctum" on Steam, and in May of 2013 they released "Sanctum 2". These games are most often described as a mix between First-person shooter and Tower defense. You find yourself in a futuristic setting, fighting aliens with a fair bit of humor. The player chooses how much resourses to distribute on automatic towers or his or her own weapons. Both games featured the possibility to collaborate with your friends to beat the levels. One of the founders, Armin Ibrisagic, was at DreamHack in November 2013, where I got a chance to talk to him. DreamHack "What is DreamHack?" you ask? Only the world's largest computer festival, held multiple times a year in Jönköping, Sweden. According to Wikipedia "It holds the world record (as recognized by the Guinness Book of Records and Twin Galaxies) for the world's largest LAN party and computer festival, and has held the record for the world's fastest Internet connection, and the record in most generated traffic." I also got an interview with one of the organizers of DreamHack, but that you will hear another day. Today we focus on Sanctum, and how the market looks for smaller game developers.

This Episode is kind of a direct response to HPR1343 by Laindir, where he explains his awesome way to decode the morse code in HPR1216. For the fun of it, I start right out by digressing into a memory of mine. It is about how I tried to decode morse code telemetry from the AO-21 amateur radio satellite some 20 years ago by using a CBM-8032 computer. After that I reveal the easy way to decode HPR1216 by using the CW mode of the program FLDIGI. Along the way, I mention the use of "monitors" in pulse audio, which are selectable in pavucontrol as input sources for audio applications. This is an easy way to loop back sound output from other applications. This method also combines nicely with WEBSDR, web accessible software defined receivers, all over the world. These may be used if you want to throw some real world signals at FLDIGI to play with the different modes. For listening to amateur radio communication I recommend to start out with one of these modes: CW (morse telegraphy), PSK > BPSK31 (very common, narrow band tele type mode) and RTTY > RTTY-45 ("original" radio tele type). For the typing modes you might want to check also "View>Waterfall>Docked scope" or activate "View>View/Hide Channels". Finally I add a tip about using OSS-wrappers like aoss, from alsa-oss, and padsp from the pulseaudio-utils package, to run old OSS applications. I use this primarily for siggen, a suit of command line / curses applications for generating audio signals like sine wave, rectangle and so on. NOTE: There is one stumbling block with pavucontrol, which I forgot to mention in the recording. Applications will only show up as playback sources or recording sinks when they actively use the interface. That is, the alsa player source will only be visible while playing, in the same way as an audacity sink can only be seen while the recording is going on.

Recycled Electronics and Gnu/Linux Used for Education. Reglue, in a nutshell, gives free Linux computers to under privileged children and their families. From their website: According to our estimates and those of the Austin Independent School District, there are over 5000 Austin students who cannot afford a computer or Internet access. Reglue wants to reduce that number by as much as we can. Since 2005 we have provided 1102 disadvantaged Austin-area kids and their families a computer. These kids cannot grow and compete with their peers unless they have a computer and Reglue focuses on giving these kids the tools they need. http://www.reglue.org/ To find out more about Ken Starks - Find him on Google+ Ken's Blog http://linuxlock.blogspot.com/2009/08/let-their-eyes-be-opened.html

This episode introduces the discussion of Frames in LibreOffice Writer by opening the Properties window and looking at the first tab, Type. Becuase there is so much to discuss about this tab, it is the only one we will look at in this episode. In the next episode we will wrap up the discussion of Frame properties by looking at the ther tabs in this window Links The written version of this tutorial can be found on my Web site at http://www.ahuka.com/?page_id=476

Nido Media invades the Early Morning Show hosted by colleague host Brenno de Winter to talk about his talk on Censorship and Hacking in the Netherlands. We discuss the situation of Alberto Stegeman, who proved the lack of security on Schiphol by touching the plane of the Queen. Brenno's own adventures with the Dutch transportation card. Henk Krol showed a medical system's security, a system considered to be "Top Notch Security", hinged on a (shared) password consisting of 5 numbers. He also talks about the Dutch Responsible Disclosure procedure and what is wrong with it, including examples such as Hans Scheuder who found a flaw in habbo Hotel. Ilyam saw his little brother and sister taken away by the Child Protection Services by accident and decided to film it and go public with it. Indigo - system for registering people immigrating to the netherlands. Contains markers like "You are ready to be removed". Russian Activist fled to the Netherlands after he was let out of jail. Here he got cought in a system named 'Indigo' which is used by the immigration service. One of the flags this system can set on people is 'you are ready to be removed'.

Listen to the man who created the database YOU use everyday, today on Hacker Public Radio. "There's no reasons to use MySQL anymore."-- Monty Michael Widenius at FSCONS 2013 A couple of months ago I attended FSCONS 2013. There I met Michael "Monty" Widenius, the driving force behind both MySQL and MariaDB. This is a guy who loves being a developer and he loves Open Source software. He named MySQL after his daughter My, and the new fork MariaDB got it's name from his other daughter Maria. Monty was invited to FSCONS 2013 to give a speach entitled "The MySQL and MariaDB story", and the synopsis on fscons.org says: "The story of how MySQL was created, why it was successful and how it grow until it was sold to Sun, who was then overtaken by Oracle. It will also cover how and why MariaDB was created and what we are doing to ensure that there will always be a free version of MySQL (under the name of MariaDB). The talk will also explains the challenges we have had to do this fork, especially the merge with MySQL 5.5, and the various systems (like buildbot) that we used to build the binaries and how we are working with the MariaDB/MySQL community." -- https://frab.fscons.org/en/fscons13/public/events/51 That presentation can be found on YouTube, and I encourage you all to have a look at it. "Michael Monty Widenius: The MySQL and MariaDB story": http://youtu.be/JxyBNdwmpzM If you have not yet made the switch to MariaDB, now is the time! Monty also asks everyone who uses MariaDB to activate the anonymous plug-in, so that the developers might know what to focus their attention on. If you wish to look Monty in the eyes, you have the opportunity to do so, as this interview was video recorded and will be realesed on YouTube or similar.
