It works on so called smart meters using a P1 port, it can monitor solar panels but it also works with regular old analog meters. I have an old style analog meter but I like gadgets and monitoring / reducing my energy usage just as much as the next guy so I bought one. It has an optical sensor that you paste (with tape) on your meter and that detects a little black bar on the rotor disc and using a rpm factor on your meter it calculates the electricity used. I has some trouble with the device when I set it up, it turned out to be aligned wrongly. It sometimes missed the black bar, so the numbers were incorrect. I wrote a little application using Qt and QML to show the raw light sensor values in a line graph to help me align the YouLess correctly. This post tells you more about the application, which of course is open source.

The Play Store version must be updated to target API level 33. For Windows and Linux I'm building the app automatically in a CI environment but the Android build was still a manual process. Until now, because after a bunch of messing around with Android NDK versions, OpenSSL library paths and Qt compile flags I can automatically build Leaf Node Monitoring in my CI. I'm using Woodpecker CI and that requires every build step to be executed in a Docker image. There are a few Qt docker images floating around but they are all using the pre-built 5.15.2 version by extracting it from the Qt Online Installer. That version is quite old, 5.15.15 LTS was released [a few days ago for Commercial License Holders](http://web.archive.org/web/20230902132649/https://www.qt.io/blog/commercial-lts-qt-5.15.15-released) on August 31, so after 1 year it will become available as open source. My docker image builds Qt from source using the `5.15 KDE Qt Patch Collection` branch for Android and it includes OpenSSL. This is as far as I know the most up to date docker image for Qt 5.15, currently at 5.15.10 LTS.

Major new features include a responsive and adjustable layout, massive performance improvements and a new check type, allowing you to execute external processes, for example, the nagios/monitoring plugins.

This post looks at a few other projects that sell GPL software and it's a bit of a progress update regarding my plans and software.

At first I thought of it as a hosted service, probably something monitoring related, or high-available cloud hosting-ish. That's the kind of stuff a sysadmin dreams of.<br><br> Now that I'm a developer for a couple of years, exposed to a few different languages, design patterns and software architectures, that idea is still lingering around, but no longer focused on a hosted piece of software. The web is just too fast paced, bloated and way too much work compared to a piece of cross platform software.<br><br> In my spare time I've been chugging along on a piece of software, which I'm contemplating selling. In my case the commercial aspect is made more difficult because I also want to release the software with a GPL license.<br><br> This post describes the initial hurdles I'm encountering, next to just programming the software.

Now, how many of those articles just use a linux server (vps) somewhere with some native apps, but mostly SSH to that server? Well, what if I told you that you can run a full blown IDE, the best IDE for C++ there is, CLion by JetBrains, on Android? Including compiling, just native GCC, CMake, GDB and all the stuff you are used to? Just for fun I've installed CLion on an old Samsung Tab S2 I had lying around, using Ubuntu in a chroot. It works way better than I'd expected, with a Bluetooth keyboard and mouse it's almost as if your on a desktop. I wonder if you could run Android Studio and use the tablet to compile app's for itself. This article shows some photo's, including a mechanical keyboard, different window managers and had instructions to replicate this setup.

After a few years (!) my old phone stopped receiving calls making it time for a new one. The new phone has Android, which allowed me to install a system wide adblocker, Blokada. It works by posing itself as a local VPN, filtering advertisements, trackers and all kinds of nasty things that spy on you or bring in malware. It does not require root access on Android, it's open source and best of all, it works very well. In the first three days of usage it has blocked over 5000 ads and trackers, including 400 when I was asleep. Sat, 16 Feb 2019 00:00:00 GMT Sat, 16 Feb 2019 00:00:00 GMT
