CSS Styling of Select

This has plagued my life for a 5 month period in 2024. Thankfully, this is almost over, and I'd rather force everyone to Chromium-based browsers instead of waiting for Mozilla to build its support for it. The <select> element can now be customized with CSS (Chrome for Developers blog).

People demand too much of online web framework courses

This is a thought I shared on the Ruby Brasil WhatsApp group, when a user manifested that there's no course now that helps a beginner or a React developer to move into Ruby on Rails. This is not about Ruby on Rails, it's about any course on any web framework nowadays. A Ruby on Rails course is tasked with the gargantuan task of teachin...

The World needs non-founders

I learned about myself around a decade ago that I wasn't founder material. I'm incapable of visualizing something from nothing, which is (to me) the defining talent necessary to be a founder. However, I'm pretty good at helping a founder bring his vision to market. Unfortunately, the World doesn't seem to care nearly as much as it shou...

Just sad

Today, I'm here hearing the sounds of a possum trotting around the backyard and thinking of all the ways I'm allowing myself to sabotage my own progress in life. I can't go on trying to please people, trying to say what they think they want to hear. But then, this was what I did all my life, and it's hard to think of some other way to ...

The Correct Amount Of Compression

Just after publishing my previous post about TailwindCSS, I took part in yet another discussion about the framework over what I believe is another misconception: that TailwindCSS is somehow against the Don't Repeat Yourself (DRY) principle. This is far from the truth. The DRY principle, in my experience, is stretched beyond its meaning...

The two main concepts behind TailwindCSS

Design from the smallest screen size to the biggest, instead of biggest to smallest; sizes are calculated referencing 4px as 1 unit. These are the two most important concepts of TailwindCSS, but they're not understood nor followed nowhere near enough. The first is a mental model based on the current state of web development, where the ...

Being confidently humble

While reading this wonderful X thread by @dieworkwear about how Tristan Tate erroneously confuses his style as one matching that of Cary Grant, a thought crossed my mind: it's so easy to fall into a trap of your own ego. This goes both ways, for being too humble is just as bad as being too confident, but the later seems worst to me, as...

Note To Self On IDEs

Some languages demand IDEs. Some don't. On those who don't, you can't get any value from an IDE until a certain level of skill. Once you stop fighting the syntax and basic programming concepts, you can finally enjoy the power the IDE gives you. That's until you're good enough at the language, and your knowledge is big enough on how to ...

Giving yourself credit is hard

I've spent most of my days doing things and never listing them on paper. I never celebrated a milestone or achievement, as they went by without receiving any notice from me. Whenever you feel like what your time flew by, stop to remember and list the things you did. Almost always, I get tired before I finish, because there's just too m...
