Vision and Sound From the Ideally Bare Numeric Impression giZmo

erlehmann Re:Oops, forgot the C compiler part. (38 comments)

This page asserts that "Xcode 4 is a free download for all members of the iOS and Mac Developer Programs.", continuing "Sign in to your account to begin the download." and according to Apple, an account costs 99$/year.

Maybe I am missing something big here, for example "free" meaning "free" as in "free beer if you buy a subscription", but I have since suggested installing Debian. Proper package management makes it vastly easier to install and develop software.

Vision and Sound From the Ideally Bare Numeric Impression giZmo

erlehmann Re:libglitch and making music a with C compiler (38 comments)

The glitter.py script is your friend; it just outputs the audio bitstream. You can pipe that into sox but I wouldnt know how to capture the output of this in Windows *SCNR*.

Working example that outputs 16 seconds of the track "sidekick" (128000 = 8000 * 16): ./glitter.py `cat tracks/sidekick.glitch` | head -c128000 | sox -c 1 -r 8000 -t u8 - sidekick.wav

Vision and Sound From the Ideally Bare Numeric Impression giZmo

erlehmann Oops, forgot the C compiler part. (38 comments)

Before IBNIZ, viznut was using a C compiler to, well, discover minimal music. You should read his paper regarding algorithmic composition using small programs. und check out my repository of formulas for C programs that generate sound.

People without easy access to compilers (I met a gal a few days ago who had old OS X and no 99$ to spare for a dev account) should still check out a track from the repository as wave file to get an impression of the style.

I also wrote a program generating a crude chiptunes version of the IT crowd melody (of course, the melody is not algorithmically generated, but rather encoded in the source, feel free to consider that cheating).

Vision and Sound From the Ideally Bare Numeric Impression giZmo

erlehmann libglitch and making music a with C compiler (38 comments)

I wrote something similar to IBNIZ, yet vastly simpler, a composing software called glitched (needs pygame 1.9.1). The forth variant I use has no subroutines or recursion and is not even turing complete and the stack has only 256 fields. However, it is compatible with that of several other implementations (see README). Like IBNIZ, it has live editing and stack visualisation.

It is important to note that sound made with this kind of tools is not limited to chiptunes. There is a video of an older version of glitched, doing Karplus-Strong-string synthesis.

(Apologies in advance to the users of a totally unrelated glitch library, which is also written in python. I have met one of it's developers last night and we agreed insane troll logic dictates a merger of our two projects to rectify the namespace collision. I may have to bring that up again when he is sober.)

Notch Announces Minecraft 'Adventure Update'

erlehmann Re:Rewrite in C/C++ (142 comments)

There is a project called Minetest-c55. It is not as featureful as Minecraft, but written in C++ (using Irrlicht) and licensed under the GPL2 (or – as I remember – at your option, any later version). You can check it out on Bitbucket.

Disclaimer: I maintain a fork called Minetest (Minetest Delta) with some added features (new block types etc.), which can be found on GitHub. Look at the screenshots.

xkcd To Be Released In Book Form

erlehmann Re:Limitations of Dead Tree (198 comments)

That really isn't supposed to happen, but then I only tested it with Gecko and Webkit. What Opera version are you using ?

xkcd To Be Released In Book Form

erlehmann Re:Limitations of Dead Tree (198 comments)

Used to love XKCD.

Me too, I think the noise ratio is going up for at least a year. But then he is not at NASA anymore, so he probably does less math stuff. I think another problem is that honest criticism is not taken into account -- actually I asked Randall on IRC and he said that he fears getting obsessed with quality and prefers not worrying. While I see that this might be enjoyable, I think a little more thought couldn't be that damaging; just compare his approach to the Debian/OpenSSL disaster to my one to see what I mean.

Internal Instant Messaging Client / Server Combo?

erlehmann Re:wtf (360 comments)

IMO, an "educated" opinion from a technical crowd is in any way better than a simple Google query. I don't know, for example, how Google could possibly have a differentiated answer to the pros and cons of particular clients.

Internal Instant Messaging Client / Server Combo?

erlehmann IRC is obsolete (360 comments)

Unless you are looking for massive scalability (as in: 500 users in a single chat room), Jabber / XMPP can handle everything better than IRC. There are things like automagic contact lists (have everyone in your department on the list, centrally administrated), working encryption, publish-subscribe ... and of course the XMPP standard is easy to extend, as it's XML based.

Internal Instant Messaging Client / Server Combo?

erlehmann Re:Pidgin (360 comments)

considering that its been around for 5 years, the answer may not surprise you - or anyone for that matter: yes it is. i know only of one reliable way to crash it and that was a problem with the xmpp specification and has since been fixed. even running svn - which i do - does not necessarily mean there will be any instabilities.

Internal Instant Messaging Client / Server Combo?

erlehmann Re:Pidgin (360 comments)

While Pidgin may be a reasonable multi-protocol client as a Jabber client I would suggest Gajim, which also does PGP and esession encryption (Pidgin cannot do either, AFAIK).

Disclaimer (possible conflict of interest): I contributed the :3 smilie to the Gajim icon set.

Smart Spam Filtering For Forums and Blogs?

erlehmann Bad Idea (183 comments)

As someone who once used text browsers, I can only advise everyone not to do this - it breaks accessibility at a fundamental level: I got banned from a forum once because they mislabeled fields.

What however, works really great for comment spam is a simple question like "What is the name of Barack Obama ?".

Microsoft Treating "Windows-Only" As Open Source

From http://www.opensource.org

Open source doesn't just mean access to the source code. The distribution terms of open-source software must comply with the following criteria: [...]

German Member of Parliament supports Pirate Party

erlehmann erlehmann writes  |  more than 5 years ago

erlehmann writes "On todays rally against internet censorship in Berlin, German long-term member of parliament Jörg Tauss announced he had quit the Social Democratic Party (SPD) and will support the Pirate Party in the upcoming elections (Twitter status, press statement, both in German). Tauss, Member of Parliament since 1994, is widely regarded as an internet expert and was one of only 4 politicians of the ruling coalition voting against the bill implementing secret lists of censored web content under the guise of fighting child porn, which has since become law.

Critics point to an ongoing investigation against Tauss regarding child porn, while he himself says he only purchased the pictures in question to prove that the internet is not a primary distribution channel and had hopes of blowing up a child porn ring. The Social Democratic Party has asked Tauss to resign from parliament after he quit the party."

The Dawning of Internet Censorship in Germany

erlehmann erlehmann writes  |  more than 5 years ago

erlehmann writes "This week, the two big German parties ruling Germany in a coalition have had the final talks on their proposed internet censorship scheme: Under the disguise of fighting child pornography, DNS queries for sites on a list shall be given fake-answers that lead to a site with a stop sign. The list itself is maintaned by the German federal police (Bundeskriminalamt).

German Blog Netzpolitik (literally "net politics"), details the history of the censorship plan and the protest movement that has formed over the course of several month. Over 128k citizens have signed a petition protesting the law, yet to no avail."

Howto prevent metacrap? Killer video CMS features?

erlehmann erlehmann writes  |  more than 6 years ago

erlehmann (1045500) writes "I am one of the developers of Yolanda, a Free Software video CMS. We wanted to use only free software and open standards, but every other Video CMS we found used Adobe's Flash. We decided to use Fluendo's Cortado applet instead to play Ogg Theora video files. We also use Creative Commons licensing. One of the next things we will implement will probably be an automatic submission to a Bittorrent tracker upon upload of large videos.

Naturally, questions arise: First, how can we motivate People not to submit metacrap but useful meta-information ? Second, what are the killer-features you would like to see in a Free Video CMS ? Third, what use-cases come to your mind aside from Universities presenting lectures online ?"
