There are several astronomy databases that store various information about space objects such as stars and planets. Some (most?) of those databases expose their data via TAP interface, so it can be queried using ADQL.
Here I’ll be telling about how to get data from such sources and what sort of issues/problems one can encounter.Read more

Like many other teams, we have a fair amount of 3rd-party dependencies in our project (a C++-based SDK, that is). Like fewer other teams, we store those dependencies source code right in our project repository and we build them together with the project sources every time. This is of course a tremendous waste of time and CPU cycles, as it would be much more efficient to build dependencies just once (per version) and link to already pre-built binaries.
But where to store pre-built dependencies and how to fetch the correct variants for various platforms, toolchains and configurations? Our investigation on the matter led us to Conan package manager.Read more

For a long time in our team we’ve been storing logins, passwords, keys and other things like that in personal password managers or just plain-text files, spread around people’s machines, and no one had the full set. Finally, we decided to stop this chaos and start using one common passwords database.
Having evaluated several options, we chose KeePass. It’s not exactly meant for multi-user usage, but we came up with some sort of workaround.Read more

A couple of years ago we came to a point when having a car had become more of a necessity than a luxury. Having spent about a year to get norwegian driving license, we entered a leasing contract for a new BMW i3.
Here I’ll be talking about the leasing process and in general about the experience of owning an electric car in Norway.Read more

Last time I needed to handle a C++ library project with CMake. This time I was tasked with creating a deb package for one of the libraries in our SDK.
And what would you know, CMake can handle packaging too - with CPack utility.Read more

It is amazing what kind of crazy ideas people might come up with. One of our users decided that they want to use our visualization engine inside their Qt application on Windows and Linux (so far so good) and also to build a version for WebAssembly to target web-browsers (fucking hell).
Very surprisingly to me, this actually works!Read more

Some time after we started to publish our packages to Azure DevOps Artifacts, users told us that they cannot see new versions of the packages until those are “promoted to Release view”. And indeed, there is a concept of “views”, and packages can be “promoted” to certain views:
Apparently, that is the case when someone consumes packages not directly from your feed, but from their own feed with your feed being an upstream source.Read more

Apparently, Apple thought that we will be delighted to get fullscreen update prompts on Apple TV like this one from time time but mostly when you expect them the least:
They just show up randomly on system start or simply on top of an application, if you leave it unattended for some time. And there is no setting in system preferences which would allow you to disable those.
You can, however, blacklist Apple update servers with firewall or DNS, and that will stop these prompts from showing up.Read more

I needed to set-up a new website with HTTPS and so I took Let’s Encrypt procedure from my past instructions. But to my surprise, Certbot is installed via Snap now, which is just retarded. That discovery triggered me to remember that I read about other ways of getting Let’s Encrypt certificate, such as acme.sh.
On top of that, last month Electronic Frontier Foundation (creators of Certbot) announced that they have joined the hounding of Richard Stallman (here’s a screenshot, “just in case”), so now they can go fuck themselves for sure.Read more
