Beloved Software

Tuesday, February 26th, 2008

Here’s a list of free software tools and libraries that I have come to love.

TCLAP is a Templatized C++ Command Line Parser library that makes your wildest command line parsing dreams come true. Its usage is so simple, it’s almost ridiculous. But it not only has all the features you can imagine but also comes with very well written manual.

Next is Prototype, the famous JavaScript Framework that turns formerly painful JavaScript development into a breeze. I just love how easy it is to develop with Prototype. It hides browser dependencies and makes code readable.

A very special piece of software is TiddlyWiki a reusable non-linear personal web notebook. I use it to document my research and write my thesis. It’s ingenious. In some sense it can also be seen and used as an archive that puts documents into context.

When it comes to text editors I’ve been in love with Vim ever since I attended my first C lectures. When used to the interface code editing at the speed of light is possible. To be fair I also like Notepad++ very much.

When it comes to graphics, layout and design I rely on Inkscape – an extremely powerful and easy to use vector graphics editor. It’s under heavy development and great features are added almost every hour. Nevertheless it is very stable.

I’ve been looking for decent UML modeling tools forever. Seriously. There’s a whole bunch of them out there and I tried a lot of them. Until recently I have been unable to find one that doesn’t suck. Then I discovered BOUML. It’s free and fast. Despites its plenty features it doesn’t come across bloated or sluggish.

Speeches, talks and presentations

Thursday, January 10th, 2008

One of the draft blog-posts that has been piling up forever is an assorted list of interesting videos of speeches, talks and presentations. Right now seems to be a good time to share them.

But first of all a list of great video-talk sources:
www.ted.com the website of “Technology, Entertainment, Design” featuring great talks given by for example Al Gore
google techtalks the google tech talk youtube page
www.bigthink.com a new place featuring interviews from all kinds of important and intelligent people about all kinds of topics
www.videolectures.net a place that provides free and open access to high quality video lectures presented by distinguished scholars and scientists.

And here the talks I really enjoyed listening to in the last weeks:
7 Habits For Effective Text Editing 2.0 a talk by Bram Moolenaar, the creator of VIM about efficiently using VIM
Resource Aware Programming a very interesting talk by Walid Taha
Linus Torvalds on git and git by Randal Schwartz
Quicksilver: Universal Access and Action by Nicholas Jitkoff the creator of Quicksilver – an extremely interesting and inspiring talk

CUDA Link Collection

Tuesday, November 6th, 2007

Here’s a list of CUDA related things on the web. CUDA stands for Compute Unified Device Architecture and is a GPGPU technology created by NVIDIA that allows a programmer to use the C programming language to code algorithms for execution on the GPU. The official website can be found here.

Update: NVIDIA introduced the new CUDA Zone website: http://www.nvidia.com/cuda a convenient way to access everything related to CUDA.

If you happen to know more CUDA related links (e.g. projects that use CUDA) feel free to leave a comment.

Minor Updates

Friday, November 2nd, 2007

There have been no updates for quite some time. Besides work there’s not much time to write articles. However I updated the blog under the hood as comment spam kept piling up. So now I’m driving akismet a spam filtering service created by Automattic. Hopefully this helps. I also optimized font-sizes throughout the blog for a more pleasant reading experience.

Furthermore the draft-posts keep getting more and more. Among others there’s some C++ stuff I’d like to share, some CUDA related code I wrote and a Science Fiction article that’s not quite finished. Hopefully some of this stuff will get published some time in the near future. Stay tuned!

Update: so far the askimet spam filtering service works great. No more spam! Hurray!

Favourite Music

Saturday, August 25th, 2007

Recently a couple of records were released that I really enjoy a lot. The first to mention would be “An end has a start” by “The Editors”. It was releases some day in June and at first I did not like it. I’m not even sure if it was the actual record I was listening to but I thought it was boring and rather pathetical. But after listening to it again a couple of weeks ago I began to really like it a lot. Favorite tracks would be “The weight of the world” (I know a couple of people who really should take the lyrics of that song to their heart) and “Bones”. I love how the singer belts out the words “Retreat, retreat” in that song and of course the fabulous phrase “The love you felt to equal the pain you’ve gone through” not to forget the dynamic and especially danceable style of the song.

As for music to dance to: check out “Idealism” by “Digitalism”. From what I’ve heard a very new band from Berlin. All in all topnotch dance music, an exciting mixture of electronic and rockmusic. There are rocking tracks like “Idealistic”, some more relaxed downtempo tracks like “Apollo-Gize” and some Prodigy like dancefloor hits like “Homezone” but all are really funky and a lot of fun.

arctic_moneys_favourite_wort_nightmare air_pocket_symphony

Already released in April was the second kickass record by the “Arctic Monkeys”. Awesome piece of music. Most favourite song from that LP would be “505”. Without knowing the story behind that song I bet it’s about a tragic, wonderful, pathetic, romantic, rockstar like love thing. So! Incredible! “But I crumble completely when you cry, it seems like once again you’ve had to greet me with goodbye.”

The fourth record is also very special (of course). It’s “Pocket Symphony” by “Air”. Minimalistic downtempo music to relax or concentrate (I listen to it when I’m working). But make no mistake. It’s not shallow music without soul or message. Listening to for example “One hell of a party” gives me the creeps. In a positive way! And also the lyris of “Photograph” are ingenious if you ask me: “I would like to own your photograph, the angels cry to have your photograph, as if you were awfully made for life, as fortune favor fools like candle light.”.

All new

Thursday, July 19th, 2007

All new on the echelon blog. The layout has undergone a severe design rework – it looks much prettier now. Also check out the supercool new navigation and blog-description.

Suomenlinna

The blog is now driven by Wordpess. Even the hosting changed as this webserver now runs on one of those new fancy server grids. Took long enough to make those changes but now everything is running very smoothly again and new posts are about to come. As for the RSS feed: it is now located at http://www.soa-world.de/echelon/feed/.

Good Games

Monday, April 9th, 2007

No, this is not about the coolest, best and most spectecular new video games but about good video games as in “doing good“. HopeLab a non profit organization in the area of San Francisco has dedicated itself to combine rigorous research with innovative solutions to improve the health and quality of life of young people with chronic illness.

Their first and most popular product is Re-Mission, a “challenging, 3D shooter with 20 levels that takes the player on a journey through the bodies of young patients with different kinds of cancer. Players control a nanobot named Roxxi who destroys cancer cells, battles bacterial infections, and manages realistic, lifethreatening side effects associated with cancer”. Watch the making of video here.

The other game might not entirely fit in the category “good game” but it’s another exepctional game. PeaceMaker by Impact Games is a game where you either play the Israeli Prime Minister or the Palestinian President. It is inspired by real events in the Israeli-Palestinian conflict and your goal is to achieve a two-state solution in order to bring peace to the region. Read an extensive game review on Gamasutra here.

I like the idea of games that “do good” a lot and I’m wondering if a MMOG such as a browser game could be designed to do good too.

Renaissance of the Command Line

Thursday, March 8th, 2007

Recently I noticed some odd stuff. Launchy – an open source keystroke launcher for windows. Start++, a Vista tool that enables users to launch programs, open websites and play music by typing simple commands into a textbox.

Launchy

Start++

Are they reinventing the unix shell? Well, not exactly but by some means yes, they are. That’s no surprise. Interacting with a computer via the keyboard is much faster than using the mouse. Especially when your hands reside on the keyboard, e.g. while writing text or during a chat conversation. I think it’s great that people are rediscovering this advantage. Creators of IRC clients for example have been including this feature for a long time.

For the very same reason I prefer the VIM editor and use the bash even on my Windows Systems with the help of Cygwin.

The Future of Desktop Environments

Thursday, March 1st, 2007

Lately quite a lot of videos presenting future desktop environments emerged. All of them are really cool so I’d like to summarize and share them.

multi-touch-sensing desktop

A very popular one is a TED talk by Jefferson Han given in February 2006. Mr. Han presents a “multi-touch-sensing” screen which is basically a touchscreen which “recognizes multiple simultaneous touch points” and even pressure. Sounds boring? It’s not. Watch the video and see for yourself.

This however are still dreams of the future. A not so far away and really cool desktop environment is the BumpTop Prototype. It’s a project that aims to “enrich the desktop metaphor with expressive, lightweight techniques found in the real world”. A very cool video is available here.

But one can enjoy fancy new desktop environments today. The Beryl Project is an OpenGL accelerated desktop for the Linux operating system. And boy does it look pretty! There are two videos available here and here.

Wallpaper Roundup

Here’s a quick roundup of wallpapers or images that are so cool you must use them as wallpapers. Almost all of them can be found at deviantart.com. Included are some nice freehand drawing pieces, somewhat girlish but beautiful vector art, photos and manipulated photos and nice science fiction space stuff.
