I'm Ulf Åström and this is my personal homepage. I don't advertise this place much so you probably know already who I am and what you are looking for. The purpose of this homepage is to document the things I do. It is my digital drawer that you may peruse as you wish.

I sometimes neglect maintaining this page. If you find something that's horribly out of date, let me know (or don't! "LOL")

Stuff I Have Been Busy With Lately (aka "Updates")

• Get Rich Quick From Bitcoin With This 1 "Weird" Trick
• Mega Drive has 16 bit memory
• My demo I'm 14 and this is cool as SHIT (Pouet) placed 3rd in the newschool demo compo at Edison 2019.
• battle-plan.el, a personal to do/checklist manager for GNU Emacs.
• I was asked, as part of a job application, to write a distributed Mandelbrot fractal renderer. My solution had two layers of parallellization, as it both spread the workload over multiple servers and also implemented multithreading on the individual server node (I got the job). Here is a massive rendering of one of the cooler locations I discovered (-0.4077+0.6003i to 0.3994+0.609i). There is also a miniature, if you're on a tight connection.
• BASMENT DWELLERS, an epic next-gen RPG about killing monsters and stealing their treasure - now on Steam!
• DATAJESUS, a webcomic (in swedish only)
• I designed an "I ♥ HICCUPS" shirt - so far, no one has bought it!?

Game Development

• SLAKT, a platform shoot 'em up with a western theme
• I'm developing a roguelike called The Slimy Lichmummy (TSL for short)
• The 2014 International Roguelike Developers Conference in Berlin, Germany
• The 2013 International Roguelike Developers Conference in Poznań, Poland
• The 2012 International Roguelike Developers Conference in London, UK
• The 2011 International Roguelike Developers Conference in Visby, Sweden
• A DAY @ THE ZOO, for the 7-day roguelike challenge 2013
• "BRAABLIBS' CURSE" - a game I probably will not be making

Other Zoftware

• A serialization library for C. It converts binary data to human-readable text and back, including pointers and arrays. zlib license.
• battle-plan.el, a personal to do/checklist manager for GNU Emacs.
• A camouflage pattern generator that emulates some common military camouflage patterns. I wanted to port it to JavaScript but I haven't had the time or motivation, so now I mostly consider it a dead project. However, Gael Lederrey has rewritten it in Python.
• A small example how to do line wrapping in C

Music

• Music I've made
• My ukulele chord finder [needs rewrite; BBL]
• A script that generates random goth metal lyrics
• I sometimes record live videos of concerts (playlist on my YouTube channel)

Other hobbies

• My mahjong page
• My travel page
• My photos of parking ticket machines page
• My fishing page
• My user page at the geohashing community wiki. Geohashing is an Internet game/GPS sport about visiting random locations and having spontaneous adventures. I'm not very active anymore.
• Recycling on 2017-12-19

Writing

• Get Rich Quick From Bitcoin With This 1 "Weird" Trick (2020)
• Keep your dirty phone out of my face (2018)
• The woes of selling musical instruments (2018)
• Is "Dune" really that good? (2018)
• Kvinnor i rockmusiken (2016) - a short essay about women in rock music, written as part of my university studies (in swedish only).

Images

• Miscellaneous photos
• Some other images
• What's going on in Happy Pony Land today? A fragmentary story of commuting to work, interpreted by oddmunds. Part 1 | Part 2

Nostalgia

• My first computer, a 8088 "laptop": the Bondwell Model 8 Turbo!
• Some other assorted rarities junk I have collected over the years.
• Refresh rates for the LG 775FT monitor
• Repainting an IBM Model M keyboard - the result will surprise you!
• manwithchainsaw, a brief attempt at a webcomic.
• Small Chip Compo 01 that I hosted in 2003
• A scanned manual for the SANSUI WS-X1 6-track cassette recorder.
• Comet Hunter, a tiny QBASIC shoot 'em up I made in 2000. It's rather clunky and there's almost no challenge to it, but at the time I was struggling to release any game at all so I felt quite accomplished (download).
• Mega Drive has 16 bit memory
• Games I've played, with mini-reviews and anecdotes
• Site history

Professional

I currently work as a programmer, developing a video transcoder in C++.

I previously worked (for ~10 years) as a technical consultant in electrical engineering. I did a lot of CAD and a bit of programming. It was like living in a Dilbert strip.

I put this silly thing together to showcase my skills. If you have an interesting proposal, we should get in touch.

Other things

• My keyboard layout, with various notes
• Get yourself a random number today!
• Broom
• Spoofing Firefox useragent, to avoid e.g. Facebook pushing its Messenger app
• My page of links to other places of interest
