Until a few month ago. Somewhere I saw someone solving a Rubik’s cube and thought it might be time to figure out how that works. Couldn’t be that hard, right? Well I bought one and went to one of those websites where they explain in great detail how to go about it. http://sekalura.net/posts/20230901-textbooks/ Fri, 01 Sep 2023 09:36:50 +0200 http://sekalura.net/posts/20230901-textbooks/ I recently read a bunch of textbooks and figured it would be a good idea to write something down about them. It helps me to remember them a bit better and maybe can even assist someone else with finding the next book to read. The Phoenix Project by Gene Kim Someone told me about that book and I found the concept interesting. The idea is to explain some lessons about IT and DevOps by way of telling a story. http://sekalura.net/posts/20230503-wallet/ Wed, 03 May 2023 18:20:20 +0200 http://sekalura.net/posts/20230503-wallet/ For a couple of years now these minimalist wallets are becoming more and more popular. I had a relatively small one for a while already but now thought it might be interesting to try out a really slim one. As I am already playing around with some leather it just made sense to make one myself. So I started looking around for inspiration and then decided that I could also start with a pattern from someone else. http://sekalura.net/posts/20230424-pocket-knife/ Mon, 24 Apr 2023 22:07:33 +0200 http://sekalura.net/posts/20230424-pocket-knife/ Some time ago I was looking for a pocket knife. I wanted something slim that’s easy to carry around with does not have too many tools on it. A blade and a bottle opener was more or less all I was looking for. It turned out to be surprisingly difficult to find something that I liked. The one that came closest was the Victorinox Bantam Alox. The problem however is that I don’t like the look of it all that much. http://sekalura.net/posts/20230403-frame-bag/ Mon, 03 Apr 2023 09:34:00 +0200 http://sekalura.net/posts/20230403-frame-bag/ I do a bit of cycling. Sometimes it is useful to be able to take a few items with me. As it is more comfortable to put them into a frame bag then to carry a backpack I bought one and it is working great. It then happened a few times that I felt like a smaller one would be better and decided to try and make one myself. After looking at a couple of designs for inspiration I started to make a paper template and then cut out the pieces. http://sekalura.net/posts/20230331-headphones/ Fri, 31 Mar 2023 21:04:23 +0200 http://sekalura.net/posts/20230331-headphones/ Ok, its not really about headphones. But I have some in-ear headphones from sennheiser and they came with a small pouch to keep them in. That pouch was made out of synthetic leather. The problem with that is its limited lifespan. Especially when used regularly. And I did use it regularly. Because I liked it but it was not looking good anymore I decided to make a new one. It was a rather simple design which is basically just two sheets of fabric with some springy metal plates at the opening. http://sekalura.net/posts/20230330-kumiko/ Thu, 30 Mar 2023 12:58:24 +0200 http://sekalura.net/posts/20230330-kumiko/ Sometimes I watch videos where a maker is building some random thing. There is one named Pask Makes on youtube. He is really talented and I enjoy his videos a lot. At some point he became quite excited about this kumiko pattern and started integrating that into various builds. I do like that pattern as well and so also have build something using it. I started experimenting a bit and then decided to build one of those keepsake boxes. http://sekalura.net/posts/20230327-tau-zero/ Mon, 27 Mar 2023 10:44:31 +0200 http://sekalura.net/posts/20230327-tau-zero/ A while ago I read the book Tau Zero written by Paul Anderson. I was looking for a new book to read and that one caught my eye. It was described as a science fiction classic and did sound interesting. The story is about a space ship that continually has to accelerate because of an accident. The author than explores the effects of time dilation and it’s consequences. That does not sound to special on it’s own but the author manages create an environment where isolation is increased to an extreme level. http://sekalura.net/posts/20210524-shelf/ Mon, 24 May 2021 15:26:12 +0200 http://sekalura.net/posts/20210524-shelf/ Like lots of people I also have the problem that I never have enough space on my workbench. To improve the situation a bit I decided to build a small shelf. I had these thin plywood sheets from a previous project still laying around and so I designed it around them. They are roughly the A4 sized so it really is a rather small shelf. I cut a couple of strips and glued them together as the pillars the different levels would be resting on. http://sekalura.net/posts/20210521-high-performance-browser-networking/ Fri, 21 May 2021 15:26:44 +0200 http://sekalura.net/posts/20210521-high-performance-browser-networking/ Recently I stumbled over the book “High Performance Browser Networking” by Ilya Grigorik. It is one of those books where people say that every developer should read it. Often when people say something like that I am a bit sceptical. However I felt like reading something like that and so I started reading it. To my surprise I do agree with that sentiment in this case. It really is a book that a developer should read. http://sekalura.net/posts/20210517-7-segment-display/ Mon, 17 May 2021 14:27:28 +0200 http://sekalura.net/posts/20210517-7-segment-display/ A colleague wanted to build a clock. He had a case with a bit of history and wanted to put a simple digital clock inside. A couple of 7 Segment display elements and a ESP8266 should have done the trick. The problem was that he did not find those display elements in the size that would have fit properly. When he told me about it I also searched for a bit and then thought about what it would take to build one myself. http://sekalura.net/posts/20210430-bottles/ Fri, 30 Apr 2021 16:21:18 +0200 http://sekalura.net/posts/20210430-bottles/ This is just a small one. But I thought it might still be worth writing about it. Every now and then it makes sense to mark something to reduce the probability that it gets lost or taken by somebody else by accident. I had this with the water bottle I use to take to the bouldering gym. Lots of people have a similar one and I had one disappear on me already so I thought about making mine a bit unique. http://sekalura.net/posts/20210418-boxes/ Sun, 18 Apr 2021 20:36:51 +0200 http://sekalura.net/posts/20210418-boxes/ For some reason everybody who works with wood in some way will build a box at some point. Its hard to explain why. Maybe because its enjoyable or in some rare cases it might actually be useful to have a box. You can build one that is extraordinary complicated or so simple it barely deserves the name. As I sometimes work with wood I followed that proud tradition and have build a couple of boxes as well. http://sekalura.net/posts/20210417-oled-display/ Sat, 17 Apr 2021 12:13:46 +0200 http://sekalura.net/posts/20210417-oled-display/ Basics Every once in a while I play around with an Arduino and some sensors. Its easy to get something simple up and running and usually is a lot of fun. I’m not that good with electronics but there is a lot of helpful information on the net. I stumbled over those tiny OLED displays. They looked quite interesting so I bought some. The ones I ordered have 128x64 pixels and come with the SSD1306 driver that can easily be connected to an Arduino via the I2C bus. http://sekalura.net/posts/20210416-pipes/ Fri, 16 Apr 2021 18:32:46 +0200 http://sekalura.net/posts/20210416-pipes/ Every now and then I start wondering what I have done with my time lately. It usually comes down to working and having spend an extraordinary amount of time on Netflix watching some TV-Shows. That feels rather depressing and I have to remind myself that that’s not all I have done. And so today I decided that it might be an good to write a couple of posts about some of those little toy projects that I am almost always work on. http://sekalura.net/posts/20190717-cpp/ Tue, 16 Jul 2019 22:06:13 +0200 http://sekalura.net/posts/20190717-cpp/ It has been quite a while since I wrote some C++. I’m not exactly a fan of the language but I have a small tool that I wrote and use a lot which needs a UI. Because I want it to have fast and solid native UI and it has to run on Linux the choices are somewhat limited. There is GTK which I never really got used to and then there is Qt. http://sekalura.net/posts/20190127-between-the-strokes-of-night/ Sun, 27 Jan 2019 22:22:02 +0100 http://sekalura.net/posts/20190127-between-the-strokes-of-night/ I just finished reading Between the Strokes of Night from Charles Sheffield. And I have to say, that is a book worth reading. It is hard science fiction and starts in the not so distant future but progresses quite far into the future. It is another one of those books that really stay with you for a while. That keep you thinking. Not just about the story of the book but way beyond that. http://sekalura.net/posts/20181124-the-freeze-frame-revolution/ Sat, 24 Nov 2018 23:16:25 +0100 http://sekalura.net/posts/20181124-the-freeze-frame-revolution/ I just finished reading The Freeze-Frame Revolution written by Peter Watts. It is an awesome book. I really like the books from Peter Watts. They are so much stranger, more complex and outside the box than most other books. Its not always an easy read but always well worth it. The Freeze-Frame Revolution is somewhat tamer than Blindsight and Echopraxia. But it still comes with an extraordinary premises and ends somehow with an amazed reader starring blankly into the room while trying to figure out what just happened.
