Oops, had almost a month long delay in posting. Because my life just sucks.

Anyway, there must be something to share with you here. I'll do it like I did previously -- by reviewing my last GitHub activity. I'll gather here some random interesting things.

unpacking CRX files and rubyzip drama

If you are going to use the gem crx_unpack (for example to run headless Chrome with a downloaded extension) it will fail because it does not support CRX v3. Somehow the only documentation of the CRX format I could find is from some Android SDK and it's outdated, so the only actual source of truth is a crx3.proto file in Chromium source code. If you need it, here is my pull request that is unlikely to be accepted because the gem repo wasn't updated in 10 years, but of course you can use my fork in your Gemfile.
Oh and while I was figuring this out I found a funny drama about the gems zip and rubyzip. As I understood, many years ago when someone made a gem for ZIP archives and for some reason named it rubyzip. Then another guy made another gem and named it more obviously, and he used the same Ruby module name, so now they are conflicting. And for years they can't come to peace, lol.

another pcbr-demo page: "Ruby Web App Frameworks"

While refreshing my knowledge about available simplistic Ruby web servers I decided to pass the "Web App Frameworks" Ruby Toolbox category page through the PCBR and this trivial line of code:

TableStructured.new( Oga.parse_html(page_html_budy).at_css "table" ).
  map{ |_| _.to_h.transform_values(&:text}.values_at :_1, :Stars, :Forks, :"Latest release" }

obtains the array that you can then print like this:

          stars forks latest_release
          +     -     +             
rails     52970 20368 20230524      
rack      4679  1551  20230424      
sinatra   11908 1961  20230411      
hanami    6066  515   20230201      
padrino   3349  494   20230225      
roda      1957  138   20230511  
...

that then results in another PCBR-demo page telling you that judging by the above criteria the gem camping is "the best web framework" today but don't ask me, I know nothing about it and at first I could not even find its repo. BTW, if you ever wondered how to add GitHub link to you gem Rubygems page, then you should look into the metadata gemspec docs and use it like they did it in Sinatra for example.
Interesting, there is a web server called strelka -- it's named after the first dog that survived orbiting the Earth. The README says the dog's name is translated as "little arrow" but that's not correct. It is "arrow sign", because it's neither a bow ammunition (it would be "стрела") nor little (it would be "стрелочка") but I'm lazy to make a pull request because the repo is on Sourcehut.
And while parsing the Ruby Toolbox I learned that HTML table rows can have <th> too so I had to fix the gem tablestructured.

gem nakicommon

Decided to make the stupidest library that one can make -- a library for everything, hehe. I saw such a one that extends Ruby stdlib with hundreds of refinements but as you know I'm still a minimalist. So I made only one simple method that is needed way too regularly -- it is the Array#assert_one that asserts that an array is one element long and returns the element.

other little trivias

how bundler parses semver

Did you know how bundler parses the semver? It appears it does not know anything about the delimeters and they can be either dots, or gyphens, or even kittens, it just scans for digits.

test frameworks dependency tree

Have you ever wondered which test frameworks do test frameworks use for themselves? I clicked through some of them and here are the results I gathered:

* maxitest --- rspec
* rspec -- aruba, cucumber, rr, mocha, flexmock, minitest
* aruba -- rspec, minitest
* cucumber, rr, power_assert -- test-unit
* test-unit -- power_assert
* mocha, flexmock -- minitest
* minitest -- minitest

A good compilation of the common test automation antipatterns in Russian.

about OOP

Some insightful answer on Software Engineering SE about what's the real purpose of OOP and what this term really means.

benchmarked two more perceptual image hashing gems

Added gem dhashy to my perceptual image diffing benchmark -- average fingerprinting speed, average comparison quality and awful comparison speed.
Also added gem phasion -- average fingerprinting, fast comparison but the same bad quality as gem phamilie, probably due to the same backend.

I guess it's enough for now. Next time I'll tell you about the "compose-launcher", give you one advice for dockerizing the chromium, and tell you about one big -- yet cheap ..( -- freelance project that I've spent like a week or two on it during June.
