  • Azure DevOps Artifacts package promotion

    2021-07-21 | 10 min read

    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:

    Azure DevOps Artifacts package version promotion

    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.

  • How to block Apple TV updates

    2021-07-11 | 5 min read

    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:

    Apple TV fullscreen update prompt

    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.

    I decided to move from GitHub Pages to my own server with my own domain. Also I switched from commenting system based on GitHub issues to remark42 comment engine.

  • Let's Encrypt certificate with instead of Certbot

    2021-04-05 | 13 min read

    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 instead of Certbot

    On top of that, last month Electronic Frontier Foundation (creators of Certbot) announced that they have joined the hounding of Richard Stallman, so now they can go fuck themselves for sure.

  • Building RetroShare on Mac OS

    2021-04-01 | 14 min read

    A couple of weeks ago RetroShare has released version 0.6.6. But while download page offers quite a variety of pre-built packages for different operating systems, there is no 0.6.6 build for Mac OS (only 0.6.5 is available).

    RetroShare splash

    I found this peculiar, so I decided to try to build it from sources myself. It also seemed like a good opportunity to finally try RetroShare, as it has been available for more than 15 years, and I’ve heard many good things about it.

  • Creating a C++ library with CMake

    2021-03-08 | 17 min read

    All of the sudden I found myself in a situation that I have been successfully avoiding so far - I needed to make a C++ library with CMake.

    CMake and a library

    To clarify, this will be about so-called normal kind of library.

  • Постоянный вид на жительство в Норвегии

    2021-02-21 | 8 min read

    Наконец-то прошло больше трёх лет как я в Норвегии, и стало можно получить постоянный вид на жительство (в оригинале “permanent oppholdstillatelse” или “permanent residence permit”).

    Норвежский постоянный вид на жительство

    Забегая вперёд, самое сложное (долгое) во всём процессе это прохождение необходимых курсов по норвежскому языку. Разумеется, помимо ожидания пока наберётся минимально необходимый срок проживания в Норвегии.

  • Gollum - Git-based Markdown wiki

    2021-01-07 | 11 min read

    We needed to create an internal knowledge base, preferably based on a wiki-engine. The requirements were:

    • in-house hosting
    • simple maintenance
    • no vendor-lock - ideally, storing articles as plain-text files
    • customization and styling
    • not overloaded with gigabytes of fancy JS-frameworks
    • version control
    • Markdown markup

    From my own researching and evaluating, there are very few wikis that meet all the requirements, and out of those Gollum seems to be the best.

    Gollum wiki (original picture:

    Even though it has its own installation guide, for me that wasn’t enough, so here are my guides for Linux and Mac OS, plus some customizing and tweaking.

  • How to manually upload VIVE VR screenshots to Steam

    2021-01-02 | 7 min read

    I was playing Half-Life: Alyx and wanted to take some screenshots. To my surprise, standard F12 screenshot button did nothing, so I had to use the screenshotting functionality from the HTC VIVE software. Annoying enough, screenshots made this way do not end up in Steam Screenshot Uploader, so I’ve spent quite some time till I found how can I add them there manually.

    Steam Screenshot Uploader

    Essentially, the process consists of cropping half of VR screenshots, sorting them by setting their modification timestamp attribute and placing them to the right folder.

  • Installing Qt without installer

    2020-12-04 | 13 min read

    At some point (beginning of 2020 year) Qt installer started to require users to have Qt Account (again), otherwise you can’t proceed with the installation. More details in the Qt’s official blog post.

    Qt installer, account

    That’s something that already happened before, but back then community got really mad about it, so The Qt Company reverted that, and installer started to work without Qt Account. And now they fucking did it again, and apparently this time community wasn’t that mad (or there is nothing left of that community after all the stunts The Qt Company has been pulling over the past years).

    Anyway, I won’t tolerate such anal-probing, so The Qt Company (or rather its management) can go fuck itself, and I’ll be just building Qt from sources - it’s not that scary as it sounds.
