A few days ago, Sir Clive Sinclair died. I owe him, or rather his most successful product, my career as a computer scientist. I bought myself a ZX Spectrum in my early teens, taught myself how to program it, and never looked back. The ArsTechnica obituary calls the Spectrum a “gaming computer”, and I guess that is mostly fair. Can’t say I ever used it for more than playing games or programming games.Continue reading “Thank You, Sir Clive Sinclair”
With Covid-19 still a bit of an issue, the summer of 2021 is yet another one for “svemester” (Sverige-semester, or Sweden-vacation). There are plenty of things to see, and one place that I finally got to visit was the old oil refinery at Oljeön in Ängelsberg, home to Engelsbergs oljefabrik and the world’s oldest preserved oil refinery dating back to the mid-1870s. It is a beautiful piece of industrial history, well-preserved and with good guided tours.Continue reading “Oljeön – The World’s Oldest Preserved Oil Refinery”
Continuing on my blog posts about our Hemester (part 1 covered Bodens Fästning), this blog post will cover Hemsö Fästning. Both are fascinating places, but also rather different, and clearly demonstrate the changes from the early 1900s to the Cold War of the 1950s.Continue reading “Hemsö Fästning – Coastal Defense from the 1950s”
Due to Covid-19, this year’s summer vacation involved a “staycation”, or “hemester” as we say in Swedish. We went up north in Sweden, and took the chance to visit some military museums. In particular, the fortresses at Hemsön and Boden (fästning means fortress). Both are fascinating places, but also rather different, and clearly demonstrate the developments from the early 1900s to the Cold War of the 1950s. This post covers Boden, with a separate post for Hemsö released a few days after this post.Continue reading “Bodens Fästning – A Fortress in the North of Sweden”
Last weekend, the yearly Flygdag (Airshow) of the Swedish Armed Forces took place in Uppsala at Ärna. Huge crowds, but it was still easy to get a good view of the aerial displays that took place. In this blog post, I just wanted to share a few photos.
Last month, I (together with my family and some friends) tried the virtual reality (VR) experience that has been created for the museum in Gamla Uppsala. VR is used to let people explore the area around Gamla Uppsala, experiencing what it looked like back in the year 650 AD. 650 AD is in the middle of the Vendeltid era (before the Viking age which is typically considered to start around the year 800). At this point in time, Gamla Uppsala had been an important religious and political center for a long time. The big burial mounds that dominate the landscape to this day were already old by then, having built in the 500s.
I followed-up on my visit to the Bovington Tank Museum in the UK with a visit to the Swedish equivalent, Arsenalen in Strängnäs. It is about 100 km from Stockholm, and thus less far off than the UK variant. Arsenalen is strictly speaking a “vehicle” museum, not just a tank museum, even though a majority of the vehicles on display are indeed tanks or at least armored vehicles.
Last week, I visited the rather wonderful tank museum (http://www.tankmuseum.org/home) at Bovington in England, UK. Fascinating, and I am happy to have seem so many legendary machines for real.
Today, I visited the Portsmouth Historic Dockyard in Portsmouth, UK, together with my kids. Somewhat surprisingly maybe, the kids mostly loved it and I got to see and learn a lot of interesting history. I found it particularly usful to compare the three main ships on display: the 1510 Mary Rose, the 1765 HMS Victory, and the 1860 HMS Warrior. They show both the development and continuity of the Royal Navy over a very long period of time.
This is another vacation-related post, of the kind that I do every once in a year or so. I recently came back from a family vacation to Gothenburg (Göteborg in Swedish), where I had some time to visit a few great museums dealing with history, and in particular with military history and the history of technology.
Note: This post was caused by listening to an interesting science podcast while thinking about the theories of startups, and the connection might seem a bit odd. Still, I think there is something to be learnt here. End note.
I recently listened to the episode on Bliss, by the Radiolab podcast. As always, Radiolab manages to take a theme and connect all kinds of things to it. In this case, bliss as in happiness turned into Bliss, the man, and his invention of Symbolics. Symbolics was an attempt to create a rational language based on symbols that would not allow the manipulation of human opinion or feeling like regular languages do. It was an attempt to create an antidote to the manipulations of dictators, tricksters, and populists (Bliss himself had been briefly interned in a pre-war German concentration camp, so he definitely knew what words could do). He designed a symbolic writing scheme that was intended to only communicate ideas clearly and unambiguously and with no room for demagogery and oratory. In the end, nobody wanted to use the language for its original purpose.
During the Christmas holidays, I got the chance to compare my oldest child’s brand new Lego set with some from the mid-1980s. It is quite striking how much larger the things in the sets have become, and how much more affordable (in relative terms) Lego has become since then.
Unless you have been living under a rock I guess the media deluge has made it clear that it was twenty years ago on November ninth that the Berlin Wall fell. Wow. Without a doubt the most momentous and important event that I have lived through. Not at all on the topic of this blog, but important enough to write some personal recollections about.
I just found a fairly interesting podcast that offers a nice example on how do marketing for paper-based magazines using digital ephemeral technology. The ancient warfare magazine has a podcast that accompanies each issue, where a set of history buffs discuss around the theme of the current issue of the magazine.
I just read a fairly interesting book about the British Spitfire fighter plane of World War 2. The war bits were fairly boring, actually, but the development story was all the more interesting. I find it fascinating to read about how aviation engineers in the 1930s experiment and guess their way from the slow unwiedly biplanes of World War 1 and the 1920s to the sleek very fast aircraft of 1940 and beyond. It is a story that also has something tell us about contemporary software development and optimization.
Back in 1996, DVP celebrated its 15th anniversary. When looking through my digital and paper archive, I found this gem: The official badge and logo for the 1996 anniversary! We also produced some mouse pads with this logo on them, one of which I still use for my daily job. Pretty good quality I must say.
The picture shown here was saved as GIF for use on the web. But scarily enough, apart from a few more GIF files, I could not open or even understand the file type of most of the files from that time, only ten years ago. Our digital archives are not very robust — more on that below.
Matts Today in History: The Vasa Sinks, August 10, 1628
is the latest installment in the very good and long-running PodCast called “Matt’s Today in History”. I really appreciate the effort going into the production of it, and the perserverance of Matt in keeping it up for more than two years.
This particular issue was interesting in two regards.
First, I suggested the topic.
Second, it featured what at least seemed like real paid advertising at the start. This is thanks to PodShow, the “media network” used to distribute this podcast. The deal behind PodShow is quite simple fo the podcaster: you get bandwitdh for free, in return for the possibility of there being advertising inserted into the audio.
The reasoning behind PodShow is nicely explained in a podcast from the Stanford Technology Ventures Entrepreneurial Thought Leaders series. Here, Ron Bloom and Ray Lane of PodShow describe the way PodShow got started and just what it is. Basically, they are building a new media company, to compete with radio and television. It is not just a nice place to find podcasts. Recommended listen for anyone interested in just how podcasting can be monetized. They describe how their staff constantly monitors the various shows that they carry, and find those popular and targeted enough to carry some paid advertising. Other shows carry intros and pointers to various other PodShow shows, to drive audience to more popular properties.
Thus, the conclusion must be that Matt’s Today in History has reached some threshold of audience that makes it valuable enough to carry advertising. Great job, and a sure sign of popularity of the podcast.
