One of the best HTTP clients is the open source tool curl. With ongoing development and continuously new updates, it is worth getting everything out of this powerful tool!

And as a bonus: @bagder is friendly developer, and also great to follow here on Mastodon! So give the article a go and follow Daniel 😉

This is the first version of the cheat sheet, with some practical examples. Feedback is very welcome, and boosts as well 🚀

How I know Daniel is a friendly and funny person? I met him some years ago at a speakers dinner at Snow (NL). Had a big laugh, with him on the opposite of the table and Lennart Poettering besides him. One of the dinners I won't forget 😀

I'm working on a cheat sheet for #AWK. This nifty tool is easily overlooked, but so powerful that it really made me invest more time into learning it.

The initial version of the cheat sheet is available and ready for feedback: https://linux-audit.com/cheat-sheets/awk/

Boosts would be appreciated, and feedback even more!

What are your AWK one-liners that others really need to know and should be included?

Special thanks to @DopeGhoti

    Adding a caching layer to your app is like giving your app performance-enhancing drugs. It'll run like the horse 🐴 ... until the unexpected side effects kick in, and you realize you've created a little monster. At first, it's pure magic...then your users become your QA team by accident. Always be aware of edge cases and unexpected trade-offs.

    Like @bert_hubert I removed X from my phone. Had my account already in hibernation mode. With @nluug also leaving the platform, no more need to use the app 👋

    @alien
    Agree. That is why I announced it clearly on my X timeline a while back as well. If people value a person's messages/knowledge, then they might be persuaded to make the jump or at least try it out. I see in my bubble (not just Linux or security, but also sustainability) that people are coming over. Hopefully that continues, include leaving X.

    @pootriarch
    But is it sending actual data or does it want to get some resources? After all, this is related to profiler itself, so it may need to pull in some developer scripts (e.g. on first use, or the latest).

    Trust, but verify 😉
