Day 28 - All asides

Just stuff.

Aside: Some games

#

• Finished Volume, and really enjoyed it. Made sure to get 100% of the achievements, which was mercifully open to even someone of my limited skill.
• Purchased and played through The Beginner’s Guide. As expected, I really enjoyed it. Definitely akin to The Stanley Parable, but different enough in premise and execution to be something new.
• Finally started playing The Talos Principle and am enjoying it so far.

Aside: The near future

#

I’m definitely doing the upcoming AI course from nucl.ai, and will work it into this blog.

Aside: The slightly further future

#

After a coworker pointed it out, I was glad to see Riot Games using Erlang. It’s my intention to rewrite the IoK server emulator entirely in a different technology stack, and Erlang is very likely to be a part of that.

Aside: Cleaning up my filesystem

#

Having a lot of CDs from various parts of the world, my hard drives are full of music files with interesting sets of characters in their file names. This has caused a few problems with some cloud backup utils, some music utils, even Windows and/or Mac OS X freaking out about the files. After the dozenth annoying crash, I looked around for a quick-and-easy way to sanitize the file names. Not finding exactly what I wanted, I took some of the Ruby code I’d found and morphed it into this monstrosity:

          puts "Oops, that file already exists!"
        else
          File.rename(file_name,new_name)
          file_name = new_name
        end

    dirs_to_check.each do | dir_to_check|
      check_dir_contents(File.join(dirname,dir_to_check))
    end
  end

  check_dir_contents(DirName)

end
