If your team's mentality is "yeah the page loads slower these days but whatevs lmao" and nobody does nothing to improve things then you'll inevitably end with a broken mess of a site/platform
"Small issues add up" indeed!

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.

yesterday I drafted out the structure in a file of how I wanted a feature to work, told it to confirm that it followed the intention of how the code should work (it apparently did based on its response) and told it complete it
ended up with a broken mess and many additional things I didn’t ask for

I’ve tried being specific and limiting the scope- I end up taking more time refining the prompt than what it would take to draft out the feature
I’ve tried giving requirements to be met on one or two files- I get so much boilerplate that I still need to review and end up throwing away

That has been my experience so far too, every time I try it I just can’t for the life of me be satisfied with the results I get
it feels like I must be missing something since every other post talks about how they produce millions of lines of code and ship three features per second with AI agents

This is the main problem I have with bluesky; I do want to enjoy it and I had started to make a habit of using it more because there is great content and people here yet I can’t seem to be able to hide from posts and topics that I’ve repeatedly pressed “show less” on

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

Not having to learn everything from scratch is the benefit of already existing, refined tools; but understanding how the tools work is the duty of the craftsman

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 :)
