Sometimes you need to double check that a private key matches your certificate (if, for example, you've got multiple badly named keys on your system). You might also occasionally want to check if a certificate matches a Certificate Signing Request (CSR) Read more…

I had this happen to me a few times already. Notification Center on the Mac goes completely numb: no more notifications and the list is empty. I’m writing down the fix, so I do not have to google the forums once again the next time. Open the Terminal, then: # this usually fails, as the notification server is already running launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist # kills and restarts the notifi..

Highlights from the CodeBeam SF 2018 conference, March 15-16 2018 Once was Erlang Factory The name has changed - yearly in fact, for the past few years - but this conference is always a destination for the Erlang faithful. The premise has been broadened since the Erlang Factory days of yore to welcome other BEAM based languages, the most prominent of those being Elixir of course, but worthy mentions here are LFE (Lisp Flavored E....

A trucker delivering palletized cargo to a pier would have to remove each item from the pallet and place it on the dock. Longshoreman would then replace the items on the pallet for lowering into the hold, where other longshoreman would break down the pallet once more and stow each individual item - all at a cost so high that shippers knew not to send pallets to begin with. – The Box, Marc Levinson.

In Part 1 of this series, we discussed the two styles of IoT device evolution; one, where simple sensory devices communicate with a cloud brain and the second, where Smart Internet Devices, or SIDs (thanks to low power and in-memory computing), become more prevalent. There, we had imagined the possibility of localized nano ecosystems made up of SIDs (NEoSIDs) becoming alternatives to large IoT ecosystems. Large like the ones provided by App..

BenchmarkDotNet is a cool tool for benchmarking. It has a lot of useful features that help you with performance investigations. However, you can use these features even if you are not actually going to benchmark something. One of these features is DisassemblyDiagnoser. It shows you a disassembly listing of your code for all required runtimes. In this post, I will show you how to get disassembly listing for .NET Framework, .NET Core, and Mo..

Recently I wrote a short article about setting up an environment for programming STM32 microcontrollers with the libopencm3 library. You can read it here . I wanted to write the second part as soon as possible but I found out that even though I could, I didn’t understand everything well enough. I just didn’t feel comfortable with the subject. That’s why I started this series. I want to explore what actually happens when you program a..

I’ve been working on improved learning materials for Codename One. One of the problems with videos is that I can sometimes unintentionally drag an idea that can be explained with a single image. DPI is one of those ideas, I’m assuming most of you already understand it but even if you do, I think this graphic helps put things in perspective. Figure 1.

After my Asus N66U kicked the bucket, I considered a few options: another all-in-one router, upgrade to something like an EdgeRouter , or brew something custom. When I read the Ars Technica article espousing the virtues of building your own router, that pretty much settled it: DIY it is. I've got somewhat of a psychological complex when it comes to rolling my own over-engineered solutions, but I did set some general goals: the end ....

I published two articles on MapLayout here and here . After all that work they are now effectively obsolete thanks to a new API in MapContainer that builds component placement directly into the map itself. Unfortunately the Google API doesn’t let us position components (native or otherwise) accurately as it pans the map. This creates a small delay when panning/zooming as the components try to catch up to the map. The only workaround is..

Rowan didn’t always want to be a software engineer. In fact, he had planned to study physics and astronomy when he started university. As a teen, he spent many hours behind a computer screen, where he became more and more curious as to how software worked, and the impact that technology could have on the world.

Over the years I read several articles on how to be effective, and how the 10x engineer thing is or is not a lie and all that.
