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.

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.

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…

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.

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!

When mobile phones first appeared, they were powered by very simple cores like the venerable ARM7 and later the ARM9. Low clock frequencies, zero microarchitectural sophistication, sufficient for the job. In recent years, as smartphones have come into their own as the most important computing device for most people, the processor performance of mobile phones have increased tremendously. Today, cutting-edge phones and tablets contain four or eight cores, running at clock frequencies well above 2 gigahertz. The performance race for most of the market (more about that in a moment) was mostly about pushing higher clock frequencies and more cores, even while microarchitecture was left comparatively simple. Mobile meant “fairly simple”, and IPC was nowhere near what you would get with a typical Intel processor for a laptop or desktop.
Today, that seems to be changing, as the Nvidia Denver core and Apple’s Cyclone core both go the route of a few fat cores rather than many thin cores.

Last week, my iPod Nano (6th generation) stopped working since its power button got stuck and failed to do anything to activate the machine. I rushed out, and got myself a replacement player in the form of an Apple iPod Nano 7th generation. I must admit that I have not found any alternative to an iPod paired with iTunes when it comes to a plain stand-alone audio player. After the utter disappointment that the 6th gen nano was, the 7th gen turned out to be surprisingly good and might even be almost up to the standards of the near-perfect 3rd generation.

Apple just released their new iPhone 5s, where the biggest news is really the 64-bit processor core inside the new A7 SoC. Sixty four bits in a phone is a first, and it immediately raises the old question of just what 64 bits gives you. We saw this when AMD launched the Opteron and 64-bit x86 PC computing back in the early 2000’s, and in a less public market the same question was asked as 64-bit MIPS took huge chunks out of the networking processor market in the mid-2000s. It was never questioned in servers, however.

It is quite interesting to see how Qualcomm has emerged as a major player in the “processor market” and is trying to build themselves into a serious consumer brand. I used to think of them as a company doing modems and other chips that made phones talk wirelessly, known to insiders in the business but not anything a user cared about. Today, however, they are working hard on building themselves into a brand to rival Intel and AMD. At the center of this is their own line of ARM-based application processors, the Snapdragon. I can see some thinking quite similar to the old “Intel Inside” classic, and I would not be surprised to see the box or even body of a phone carrying a Snapdragon logo at some point in the future. A part of this branding exercise is the Snapdragon Batteryguru, an application I recently stumbled on in the Google Play store.

Selling and marketing high technology is what I do for a living. My counterpart is the customer or buyer, and I help design, build, explain, an market these products. In this role, I am most usually the expert on the domain, helping potential customers understand what we sell and why it will help them. Both at the high-level value proposition and the details behind it. Some people focus most of the their energy on the high-level value proposition, but I feel that youoften need a bit detail backing that as well.
I recently had the enlightening experience of being on the buying side instead, experiencing the transition from high-level value proposition to low-level details. It struck me as being quite similar to what the customers for our virtual platforms would experience when coming in new to the field.
I bought a camera.

Is the touchscreen the end-all of user interfaces for mobile devices? There were rumors in early 2011 that the iPad2 would lose all physical buttons (which did not come true, obviously). To me, that sounds like a really good and bad idea. Good, in the sense that a device that is all a big screen certainly looks nice. Bad, since it would be much less user-friendly than a device with some real physical buttons to press.
I have been thinking about this subject lately, after using a BlackBerry Torch 9800 as my work phone for a few months. I like the device a lot, but there are certainly some rough edges and some places where there is a UI conflict between touching the screen and pressing the buttons. At the same time, I am using both an iPod Nano 3G, and a couple of iPod Touches. I used to have SonyEricsson Symbian-based P900, P990i, and G900 smart phones which also were combined touch/press devices with a stylus.

Ever since I got my BlackBerry smartphone, I was annoyed that the display said “My Number: Unknown number” in a number of places. I assumed that this would be automatic, just like everything else information-related on this device. However, I finally worked out how to “fix” the problem by manually setting my phone number.

Following on my previous posts about broken phone browsers, phones, and cars, here is another case of “why didn’t they catch this in testing?”
We recently got ourselves an iPod Touch, to entertain our oldest child on long trips. It is a brilliant device in many ways, I can understand why people love their iPhones (even though I am very happy with the very different style of the Blackberry phone that I was given by my employer). However, I have found one weird behavior in the music player that leaves me wondering how it got through into the shipping product.

Continuing on the thread from my previous post about the testing of products that fail to find problems that become obvious to (some) users after a very short time, I just read an article (in Swedish) about how the famed Tesla roadster cars behaved when they were confronted with Scandinavian winters.

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.

I just found “The Toaster Project“, a Royal College of Art project where Thomas Twaites built a simple toaster from scratch. Really from scratch, going all they way back to iron ore and raw petroleum. In the process, he had to smelt ore, create plastic from petroleum, etc. It is a very interesting observation about the immense industrial complexity behind the very simple everyday items of our lives. I also think it has something to tell us computer scientists about abstraction.

I have installed Google Maps on my trusty SonyEricsson G900 (last of its kind, unfortunately, as UIQ is shut down and SE is moving to Nokia S60 etc.), and I find it an almost too fun and useful toy-tool. However, today, something really funny happened. For some reason, when asked to display my current location, it decided that I was in Northern Greece — to within 5000 m.

This is a follow-up to last year’s post on the Chariot Corsaire XL bike trailer we have. Now that we have a baby girl as well as our older boy, we have upgraded the trailer with a baby seat. Works very well, even though it was quite a bit of work to install it.

Now I have had my yubikey for about a week, and I have put it on my keychain. It really works extremely well! The only small issue is that I tend not to have my keys immediately within reach while at home in the house or on travel, so there is a step of “go retrieve the keys” before I can use it for login.

I been listening to the SecurityNow! podcast raving about the coolness of the Yubikey, created by Swedish startup Yubico. It seems like the device has captured the imagination of quite a few people, and I have been kind of curious about it. So I was quite pleasantly surprised when I got one a few days ago, since we are testing it as a new way to authenticate to our VPN at work.

I just got myself a new home PC, to replace my no longer very trusty five-year old Athlon-based PC. In the process, I realized I had to move my iTunes library from the old machine to the new. Reading on the web and the Apple support area made me somewhat skeptical as to the feasibility of this operation… would all my cover art, podcast subscriptions, playlists and ratings survive the move? There are many stories of failed moves and lost data out there… and moving from Windows XP to Vista 64-bit did not make the dread less.
In the end, it turned out it was really dead easy!

I don’t know if anyone has noticed, but I have finally managed to put a custom icon on the RSS feed for this blog. It is a larger version of the icon used as “favicon” for this blog and www.engbloms.se. I got the idea from the RSS feeds reader on my SonyEricsson G900 phone, which showed a few feeds with icons, but most with a generic icon.

I just read Stephen Fry’s latest blog post about smartphones in general and the Apple iPhone in particular. He really loves the iPhone, but the interesting thing to me was the wish list of future improvements to the device. In particular, support for MMS. That was one of the things that made the iPhone unacceptable to me and not really to be considered a serious mobile phone (along with no bluetooth modem).

I am a skeptic when it comes to technology. Despite working in the tech field — or maybe because I am — I always expect technology to fail or at least disappoint. But sometimes that instinct is actually wrong! Here are two recent examples when I felt “wow, that was pretty good” about some fairly mundane pieces of computerized equipment.

I should have known to expect trouble when I tried out DataViz ActiveSync on my new G900… the first thing it said was that “in order to avoid problems, we will deactivate the synchronization towards PC Suite”. Ah well. I assumed you could get it back…
But that was not so easy. I quickly realized that ActiveSync was pointless for me, since the setup I have for my data is not “everything on the corporate server, period”, which is the usecase ActiveSync is built for. But when I told ActiveSync to stop synchronizing certain categories of data, that lock it had put up still applied it turned out. With no way I could find to turn it off. So suddenly my phone just did not want to synchronize with my PC.

I just got myself a new phone, having tired of my old P990i getting a bit unreliable. It was only about two years old, but I guess I was pretty rough on it. My new phone a the SonyEricsson G900, and I am actually very happy about it.
Edit: inserted a couple of updates after a couple of more days of use.
