  • Search for a Hugo-based blog

    2020-01-05 | 6 min read

    I was working on the documentation for some project, and chose to use Hugo for it. Fits perfectly, but lacks the searching functionality. So I implemented it there, and also decided to add it to my blog too.


    It is actually a bit surprising why I didn't think about it earlier. But then again, using Google's site-specific search (ololo should be good enough for that purpose already, so I just didn't bother to do something else.

  • Apple TV, Kodi and network share

    2019-12-26 | 10 min read

    For a long time I was using Kodi with LibreELEC running on a Raspberry Pi 3 Model B device. It was pretty good, and I was going to write a post about it, but never had time for that, and now I got an Apple TV, so instead I'll write a post about using Kodi on Apple TV.

    Apple TV, Kodi and network media storage

    I'll talk about how to install Kodi on Apple TV and how to create a network media storage for it.

  • Resizing images with ImageMagick vs sips

    2019-12-12 | 2 min read

    For quite a some time I was using sips from standard Mac OS bundle to resize (mostly scale down) images. But I always had some suspicions about its results quality, so I decided to compare it with ImageMagick.

    ImageMagick vs sips

    The figure above shows results of an image being scaled down to 100px width using both tools, and as you can see, ImageMagick conversion quality is better.

  • NGINX, uWSGI and Python scripts

    2019-11-03 | 10 min read

    You have a static HTML page with a form on it. And you want this form to be processed by a Python script when submitted. And you serve your page with NGINX. To make all that work you will also need an application server such as uWSGI.

  • The fuck is this CORS and how do I send my bloody request

    2019-10-10 | 6 min read

    So I was working on some web view and I needed to send an XMLHttpRequest using JS. Usually I was working with my own backend, but this time it was a different remote host (our YouTrack instance), and my request failed with the following error:

    Firefox, missing CORS header
    Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS header Access-Control-Allow-Origin missing).
    Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS request did not succeed).

    That's how I learnt about the existence of CORS, as it turned out I never sent cross-origin requests before.

  • Players queue for Heroes of Might and Magic

    2019-09-21 | 3 min read

    It's not like we at work don't have things to do, but suddenly we decided to play Heroes of Might and Magic. So we created a virtual machine, installed the game and started a hot-seat game via RDP.

    HoMM queue

    For notifying about next players turn we created a Slack channel. But soon enough it became annoying to announce next turns manually, so I created a simple web-application for that.

  • Barefaced phone scammers

    2019-08-22 | 5 min read

    I got a phone call the other day. The man on the other end told me (with a strong indian accent), that he is from “Computer Solutions” (or something). That already sounded fishy, but he also used my full name, which lowered my guard for a bit, so I did not hang up right away.


    Right after “how are you” he said that according to their “systems” my computer is in danger, because, as they can “see”, there was some “hacking software” downloaded to my computer, and they will now help me to get rid of it.
