Force lsp-mode to update when I visit the buffer

I use lsp-mode to edit typescript project files in emacs. When I update definitions in a file, lsp flymake diagnostics are not updated in other files until I perform an edit on the other file. Having to insert a space character and then undo it to see the latest errors quickly becomes annoying. Is there a way to "trigger lsp check when I focus on the buffer"?

Getting the compilation output of asdf:load-system into SLIME

Running (asdf:load-system "my-project") in the SLIME REPL causes warnings and/or errors to be printed to the REPL, which is difficult to go through. In this post we explore a solution that does not receive much attention in beginner tutorials.

Building libpq on MSYS2 MinGW 64 bit for libpqxx

For Windows, although there is a PostgreSQL installer provided, the libpq in the installation directory cannot be used to link libpqxx on MSYS2. This post shows how to build libpq from source on MSYS2.

LD31 - FuFuFuel!

Finally! First entry ever! First time "finishing" a playable game from scratch in such a short time (less than 12 hours, dammit chores!!). Link

The original intention was to build a survival defense kind of game, with simple graphics but focus on strategy and macromanagement. I guess I was overambitious, though. Most of the planned features never made it into the game (complex targets, level-up weapons, etc.) It's way past bedtime and it's freaking Monday tomorrow...

Enjoy the game, post your scores in the comments! (Didn't manage to implement the high scores table, awww.) I'm sure I'll find time to build on the game post-jam. (After rating the games, of course!)

The horrors of a graphical programming tool

Recently I had the opportunity to use a graphical programming tool. The problem was to automate an industrial process, and what could be better than a flowchart-like tool? is apparently what the pioneers thought. The tool had been used on several other units, with varying "success". This means I had legacy code to start with. While this certainly does not speak for other tools, and of course the legacy code had a hand in the experience, I want to document here some of the horror-ful experience.

What are buffer overflows?

To the uninitiated, the jargon "buffer overflow" may invoke images of hackers and bugs and exploits, but this article shows that you can easliy have your own buffer overflow too.
