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…
How important is the documentation (manual, user guide, instruction booklet) for the actual quality and perceived quality of a product? Does it materially affect the user? I was recently confronted by this question is a very direct way. It turned out that the manual for our new car was not quite what you would expect…
This is just the first page, and as you can see if you know Swedish or German or both, it is a strange interleaving of sentences in the two languages.
When my old CM Storm mechanical gaming keyboard stopped working a while ago, I looked around for replacement alternatives. I ended up getting the new Corsair K65 RGB LUX narrow keyboard. A while earlier this year, I got a Corsair K70 at work. Thus, I can do a double review on a pair of closely related keyboards, but with different key switches, sizes, and backlighting systems.
In my sporadic series of IT fixes that I happen to find, here is another one about how to fix the load behavior of plugins in Outlook.
This is a solution to a problem that I have had myself with plugins for Outlook. I assume it works the same for other office programs. Basically, some plugins, in particular the Skype Meeting/Lync Meeting plugin, would not load when Outlook started and I was forced to manually enable it in the add-ons manager each time. Highly annoying. I managed to fix it by doing a small registry fix.
The family and I spent last week on a cruise in the Mediterranean with Royal Caribbean Cruises (RCC). It was a wonderful vacation, and very family friendly. We did a number of shore excursions and got to see historical landmarks like the stadium at Olympia where the original Olympic games were held. Lounging by the pool on the ship was nice on our sea days, if a bit crowded. Service was fantastic, and you really do not need to think much at all about practical things while onboard. It just happens. Very relaxing. If I compare it to a typical all-inclusive hotel vacation, it is definitely higher quality with the added benefit of moving around and seeing multiple places in a week.
Electric bikes have started to become common,in Sweden in recent years. It’s been a big thing in other countries for a while, so I guess they have finally matured to the point that they can stand our climate. To be honest, I never quite saw the point of such a vehicle, until my wife took a job that perfectly fit their sweet spot, and I got to try hers. It was quite a revelation. I am usually rather hesitant to believe hype, but in this case, I think we do have the making of a really useful type of vehicle that offers a useful alternative for a particular niche in the transportation continuum.
Thanks to the good folks at Vector Software, I was pointed to a conference recording on Youtube, from the Google Test Automation Conference (GTAC) 2015 (Youtube video). The recording covers quite a few talks, but at around 4 hours 38 minutes, Brian Gogan describes the testing used for the Chromecast product. This offers a very cool insight into how networked consumer systems are being tested at Google. Brian labels the Chromecast as an “Internet of Things” device*, and pitches his talk as being about IoT testing. While I might disagree about his definition of IoT, he is definitely right that the techniques presented are applicable to IoT systems, or at least individual devices.
I am a big fan of proper real decent mechanical tactile clickety-clack keyboards. Writing is my means of communication, creation, and commercial contribution to the world. I write a lot of text – both code and normal language, and I feel that I type faster, more accurately, and produce better text when using a tactile keyboard. I cannot understand how anyone cannot love them once they have their fingers on them. However, mechanical keyboards have a bad reputation for being NOISY. The rest of my family thinks my CoolerMaster Trigger Cherry MX Brown is a bit too noisy when I use it at home. Thus, when I read about the Matias Quiet Pro keyboard, I spent the money and gave it a try. If I could have the feeling of a tactile keyboard without the noise, it would be a wonderful compromise!
Now that Windows 10 has been officially out for a while, I decided to give it a try on one of my home machines. I expect that all my Windows 8.1 machines will be updated eventually – it is a free update, after all, and supposedly things should work just as well as in Windows 8.1. Just with a different user interface. Windows 10 is indeed different from Windows 8.1 in fairly significant ways, and it really feels like what would have come after Windows 7 if Windows 8 hadn’t come between. I can see why many or even most people see this as the better upgrade path, even if I lament some of the changes made.
I am using DropBox quite a bit to move files around between various machines (nothing confidential, just stuff that I need to move around and that is a tad on the large side). Today, I hit a very issue where I saved screenshots from a Ubuntu machine and waited for them to show up on a Windows machine. And they never did. Confused, I went to the web interface, and the files were indeed in place there. I could download it from the web interface without an issue. Weird. Other files did sync in the meantime, so just what was going on?
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.
I just got hit by a strange behavior in Microsoft word: the comment and format change “balloons” that pop up next to the text when using change tracking and viewing changes started to overflow their allocated balloons. The font used look very funny too. The issue was that a document contained a format specification for these balloons that used a font not present on my system, which in turn caused Word to use something like Courier to display it. Which did not look nice. However, it was easy to solve.
