I have been spending quite a bit of time in recent years developing training materials and doing trainings for Simics. There is always a discussion on how best to do training, in particular between live sessions with actual trainers and offline video and other self-study resources. I am a firm believer in the value of live training, and during our recent winter vacation up in the Swedish mountains I made myself provide a perfect example of the value of a teacher. I took a skiing lesson.Continue reading “The Benefit of Live Teachers (Applied to Myself)”
As I chronicled earlier this year (see “A Sudden Case of Cancer”), I got a Thyroid Cancer diagnosis back in May of this year. In June I went through surgery which went very well. After only three weeks, I was sufficiently recovered to travel to Greece and give a keynote presentation at the SAMOS conference. My scar prevented me from taking as much as advantage as I could have of the sun and pool, but it was possible to do at least a little bit of bathing towards the end. Now, I have reached part two of the treatment, radioiodine therapy to knock out any lingering cancer cells. Basically, I am going radioactive for a few days.Continue reading “Cancer Part 2: Going Radioactive”
I have had some annoying problems in recent months with my work laptop refusing to connect to certain WiFi login pages (more technically known as Captive Portals), essentially locking me out of the WiFi in certain places. Here is how I solved it.Continue reading “Failing to See WiFi Login Page [Captive Portal] / Solved”
I have a new blog post out on the Intel Developer Zone, about the Simics 6 device register coverage feature. I use device register coverage to look at how different operating systems use the same hardware. The differences are significant, demonstrating the (rather expected) observation that different software stacks use the same hardware in different ways.Continue reading “Intel Blog: Simics 6 Device Register Coverage”
I just started using Office 365 at work, and almost immediately I hit a hilariously bad problem in the core simple “import CSV” functionality. Basically, the Excel 2016 that I got (it is 2016, not the latest 365 that my home machine all use) does not understand Windows line endings or decimal numbers.Continue reading “Excel 2016 & CSV Import – Hilariously Broken”
A while ago, Ars Technica reviewed the Mega Sg, a modern clone of the old Sega Genesis gaming system. I stumbled on this review recently and realized that this is a fascinating piece of hardware. The Mega Sg is produced by a company called Analogue (https://www.analogue.co/), presumably named thus because they create analogues to old gaming consoles. The way this is done is different from most current “revive the old consoles” products that simply use software emulation to run old games. Instead, Analogue seems to have settled on using FPGA (Field-Programmable Gate Array) technology to basically build new hardware that is functionally equivalent to the old console hardware.Continue reading “Using FPGAs to Simulate old Game Consoles”
This year’s family vacation was spent on the Greek island of Crete, in an all-inclusive resort close to Chania on the north coast. Overall we got nice weather and an enjoyable pool-and-sun holiday, mostly staying at the hotel with a few excursions. In the following, I will go through some of the most surprising or interesting observations I made in Crete. Greek letters are cool, but I do not think we will go back to Greece any time soon when there are higher-quality places available (such as Spain).Continue reading “Off-Topic: Vacation in Crete”
Cancer – it is a scary thing, and it recently became part of my life. It is only two weeks ago today that I got my cancer diagnosis, and I am already out of surgery and recovering. It has been a very speedy process, and hopefully this will be the end of it. Getting a cancer diagnosis is a bit rattling, but there is no reason to panic.Continue reading “A Sudden Case of Cancer”
I heard about the DOOM Game Engine Black Book by Fabien Sanglard on the Hanselminutes podcast episode 666, and immediately ordered the book. It was a riveting read – at least for someone who likes technology and computer history like I do. The book walks through how the ID Software classic DOOM game from 1993 works and the tricks and techniques used to get sufficient performance out of the hardware of 1993. As background to how the software was written, the book contains a great description of the hardware design of IBM-compatible PCs, gaming consoles, and NeXT machines circa 1992-1994. It covers software design, game design, marketing, and how ID Software worked.Continue reading “DOOM Black Book – This is Brilliant!”
For the past couple of weeks, I have been using a Nokia 7.1 phone as my main phone while my main Sony phone has been off for repairs. My habit for quite a few years has been to use Sony “flagship” phones as my work phones (and way back, even Sony-Ericsson). The question this poses – how was it to use a theoretically far weaker “mid-range” phone instead of a flagship?Continue reading “Living with a Nokia 7.1 Phone”
For some reason, Microsoft has decided to hide some decidedly useful features in Windows 10 explorer behind the non-intuitive and rather unknown “shift-key + right-click” combination.Continue reading “Off-Topic: Windows Explorer Tip: Shift Right-Click”
I have tried yet another keyboard at home in my quest to find one that the rest of the family finds sufficiently silent – while still being nice to type on. While my fingers love the feeling of the super-clicky MX Blues in my K70 at work, it is not the best choice with other people in the same room, especially at home. Thus, my long-running quest for a keyboard with a nice feel but less noise. I started with a Matias Quiet, and when that broke I tried a Corsair RGB Silent Strafe with the rather expensive MX Silent switches. The “silent” was not sufficiently silent, though, bringing me to the latest keyboard I am trying: the Corsair K55 RGB.Continue reading “Off-Topic: The Corsair K55 Rather Silent Keyboard”
Late last year I was trying to do some machine learning work on my brand new Alienware 15 R4 gaming laptop. I had bought the laptop in order to have something portable with sufficient performance to actually do convolutional neural network (CNN) training and inference “on the road”. The GTX 1060 in the laptop is just as powerful as my home desktop machine, and should run Tensorflow and Keras well. I had the setup working on the desktop already, and copied the code over to the laptop. When trying to run the code the first time, I got some rather strange errors that I finally figured out meant that I was missing the CUDA toolkit. I downloaded CUDA version 10, installed, and the machine rebooted into the Windows 10 automatic repair mode.Continue reading “Windows 10 Reboot Loop – CUDA & Alienware”
I have a documented love for keyboards with RGB lighting. So I was rather annoyed when one of my Corsair K65 keyboards suddenly seemed to lose its entire red color component. The keyboard is supposed to default to all-red color scheme with the WASD and arrow keys highlighted in white when no user is logged in to the machine it is connected to – but all of a sudden, it went all dark except a light-blue color on the “white” keys. I guessed it was just a random misconfiguration, but it turned out to be worse than that.
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.
During this year’s vacation trips, we sampled an unusual number of ice cream places around Sweden & Europe. Here are some notes on a few places we visited and where I took the time to actually take some photographs…
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.
The Matias Quiet keyboard that I have been using for a couple of years recently gave up the ghost. The Enter key broke off and it seemed kind of unreliable in the USB department too – sometimes not activating when attached to a laptop, and sometimes just disappearing. I had got complaints about it being a little noisy still, despite being a lot quieter than a standard ALPS-style Matias keyboard. The replacement I got was a Corsair Strafe RGB Silent. I am rather fond of Corsair keyboards and mice, and this variant sounded promising.
Earlier this week, I attended a Google IO Extended event in Stockholm. It was really nice event organized by Google to extended the reach of Google IO across the globe and those of us who would not be able to attend live. The main event was watching the IO keynote live, but before it started we had some good team games (my team did so-so I must admit) and talks on WebRTC and real-time communications using standard web technology rather than custom plugins. Watching a keynote like this live in a theatre setting gives a different experience from just reading about it post-facto or watching it on your own where it is easy to be distracted (which is something that was addressed in the keynote…).
I had the honor to have a scheduled talk at the Embedded World 2018 show in Nürnberg, right at the start of the show on Tuesday morning. Getting to Nürnberg for the Embedded World without paying a fortune for plane tickets is tricky due to all the other people flying down from Swedish embedded and tech firms at the same time. This year, I was lucky and I had managed to get a very convenient flight at a decent price. Leaving Stockholm in the afternoon around 14.00 on Monday, flying via Frankfurt and then on to Nürnberg, arriving in the early evening just in time for a nice Bavarian dinner. No stress, no late evenings on the U-Bahn into town. A good night’s sleep before getting up and getting to the show with plenty of time to set up for my talk. What could possibly go wrong?
The USB standard has spawned quite a few connector variants over the year. Apart from the basic “A” connector (the one that you put in one way, then the other way, and finally the right way), there have been quite a few mini and micro variants of the “B” connector. Now, with “C” we seen to be approaching, finally, a reduction in the number. But it seems to me that there is a need for another variant…
I am an avid podcast listener, using podcasts as the main source of entertainment on my commute, when I go to gym, go shopping, cook at home, et cetera. In the past, I have used a long line of iPod nano devices to serve my listening needs (see my review of the 7th and final generation iPod Nano), downloading podcasts to a Windows PC and then syncing them over to the device. This worked well enough, and I kind of liked separating out the battery used for listening from the battery my phone used for calls and data traffic. But nothing lasts, and now that Apple killed off the iPods I had to find a replacement solution before my last iPod broke.
The new Windows 10 Controlled Folder Access (CFA) feature is a great idea – prevent unknown programs from modifying your files, to stop ransomware in its tracks. It is so good that I forced an early update to Windows 10 Build 1709 (“Fall Creators Update”) on a couple of my home machines and enabled it. Now, I have quickly disabled it, as it is not possible to actually use it in a real environment. It just stops things a bit too hard.
More travel notes. This time from Loka Brunn, a spa hotel and conference facility in the vicinity of Grythyttan in mid-west Sweden. The place dates back to around 1720, when an organized “Kurort” was founded. I spent a weekend there with my wife, and found the place to be very relaxing and professionally run.
After updating my Sony Xperia Z5 Premium from 2016 to Android 7.1, I noticed the settings for screen scaling (known as Display Size). The setting has probably been around since I got Android 7 (Nougat) on the device a while back, but I did not notice it until now. I tried it out, and it is kind of useful to shrink text a bit to get more onto the rather large screen of the device. But the keyboard behaves in a rather funny way…
It is summertime, and time for another off-topic blog post about travel. This year, we took our family vacation on the island of Mallorca, at the Playa Garden Hotel & Spa. It is located in Playa de Muro, between Port d’Alcudia and Can Picafort on the east coast of Mallorca. The goal was to enjoy a bit of sun & sea, and that worked out very well. It looks like we were lucky in our hotel choice, too.
Human Resource Machine, from the Tomorrow Corporation, is a puzzle game that basically boils down to assembly-language programming. It has a very charming graphical style and plenty of entertaining sideshows, hiding the rather dry core game in a way that really works! It is really great fun and challenging – even for myself who has a reasonable amount of experience coding at this low level. It feels a bit like coding in the 1980s, except that all instructions take the same amount of time in the game.
Skype for Business is an interesting beast. It is a nice little program for internal collaboration, but some of its behaviors are just super-annoying. One my pet peeves is the fact that when you get into a meeting with screen sharing you have a bunch of big heads covering up a sometimes significant chunk of the materials being presented. I finally figured out how to get rid of them. It comes down to the view mode. This little icon in the toolbar:
I and my wife recently took a short vacation in Nerja in Spain, a tourist town on the Costa del Sol. Late February was definitely low season, which made for a rather relaxing experience without the huge crowds that would be expected to fill up the place later in the year.
A recent update to the Amazon Kindle app on my Android devices introduced a severely annoying page curl animation when flipping through pages in a book. This unnecessary animation slows things down and disrupts the reading flow, or at least that is my opinion. It was really hard to find any kind of help on the Amazon pages or elsewhere on the Internet for how to turn it off. I finally figured it out, and here is how I did it so that other people with the same problem can search and find a solution…
