The only way to get rid of problems like this is to actually _care_ about what you're working on and keeping an eye out for and actively trying to fix or prevent these kinds of things
🔍 Found in a recent web performance audit:
favicon.ico → 301 redirect → broken URL → returns 13 MB uncompressed HTML
⚠️ Even tiny assets can slow your site if misconfigured.
Check static files (favicon, images, CSS, JS) — small issues add up

I edited my Cross-Site Request Forgery countermeasures research into a stand-alone article, including recommendations reusable by other projects.
tl;dr: no need for tokens or keys, modern browsers tell you if a request is cross-origin!

Cross-Site Request Forgery
Cross-Site Request Forgery countermeasures can be greatly simplified using request metadata provided by modern browsers.

it seems more bad when it’s used as the direct primary output method in a field that had a higher bar. then people are incentivized to compromise on quality, and people in power often don’t understand or appreciate quality. so everything kind of gets shittier

It’s been a rough couple of weeks, what with work consuming my soul and my coworkers my sanity
But having the most wonderful wife in the world is reason enough to push through

Asking chatgpt to analyze and give an opinion of code as if it was the “Dr House of software development” is great for both comedic effect and insightful feedback

Made a few adjustments (6 or 7) to a react component, and then started blindly removing chunks of code from it,
And nothing broke.
I’m just amazed at how purposefully out of their way someone must have gone to over complicate this component
I refuse to believe it wasn’t intentional

Just spent an hour trying to fine tune my zmk configuration because doing p+o real quick was activating ctrl+o (homerow mods) and nothing seemed to make it right...
Turns out I hand't correctly changed that single &mt to my custom &hm behavior :)

Maybe a hot take but if you've been working as a webdev for 2 years you should at the very least know how to add breakpoints and debug the code using the sources tab on chrome's devtools 😬

After tinkering with my #neovim configuration again, startup time went down to 35 ms ✨ (and all it took was making everything either trigger on BufRead or InsertEnter like a madman ☠️)

I saw this post a couple of days ago and it seemed like a bit of fun; not super polished, but it does the trick!
Even after having a very tiring week at work (damn you 10 hour work days!) it is nice to sit down and do some recreational #coding to relax :)

I started learning ⚡Zig today! Found out about Ziglings (codeberg.org/ziglings/exe...) and really liked the approach!
Doing exercises like these seems like a fun way to learn a programming language; I also feel it matches my learning process better than just glossing over the docs #zig #code
