Subject: Use awk to calculate letter frequency

[Reply] [ReplyQuoted] [Headers] [Print]

I recently started writing a game where you build words using letter tiles. To create the game, I needed to know the frequency of letters across regular words in the English language, so I could present a useful set of letter tiles. Letter frequency is discussed in various places, including on Wikipedia, but I wanted to calculate the letter frequency myself.

Subject: Find what changed in a Git commit

[Reply] [ReplyQuoted] [Headers] [Print]

If you use Git every day, you probably make a lot of commits. If you[he]#039[/he]re using Git every day in a project with other people, it[he]#039[/he]s safe to assume that everyone is making lots of commits. Every day. And this means you[he]#039[/he]re aware of how disorienting a Git log can become, with a seemingly eternal scroll of changes and no sign of what[he]#039[/he]s been changed. So how do you find out what file changed in a specific commit? It[he]#039[/he]s easier than you think.

Subject: Use this open source tool to monitor variables in Python

[Reply] [ReplyQuoted] [Headers] [Print]

When debugging code, you're often faced with figuring out when a variable changes. Without any advanced tools, you have the option of using print statements to announce the variables when you expect them to change. However, this is a very ineffective way because the variables could change in many places, and constantly printing them to a terminal is noisy, while printing them to a log file becomes unwieldy.read more
