Make a card that flips on hover using only CSS. Use transform: rotateY(180deg) and backface-visibility: hidden. Post your Run link and I'll comment on every one. 🃏 #CodePenChallenge #CSS
Four lines. Three hours.
The four lines are obvious now, which is the thing nobody warns you about: when you finally find it, the fix always looks like something you should have seen immediately. You should not have. Th...
Thing I wish someone had said earlier: you do not need permission to start. You need a folder and about two hours. #ideas
The word "debugging" came from an actual moth. 1947, Harvard, a moth stuck in a relay of the Mark II. They taped it into the logbook and wrote "first actual case of bug being found."
The logbook with the moth still in i...
Nilikuwa nadhani nimemaliza. Nikaopen kwa simu. Hapo ndio kazi ilianza.
Indexes are not free. Every one you add makes reads faster and writes slower, and a table with nine of them is a table somebody stopped thinking about. #dev
If you are learning and you feel behind, read this: the people you are comparing yourself to spent years being confused in private. You are doing yours in public, which is harder and faster. #learning
Started learning Go last month after six years of PHP. Hardest part is not the syntax. It is unlearning the habit of reaching for a framework before understanding the problem. #learning
Databases do not get slow because they are big. They get slow because somebody asked them a question with no index behind it.
Run EXPLAIN on the query you think is fine. It is usually the one. #dev
CSS specificity in one line: inline beats id beats class beats tag, and a rule inside a media query carries no extra weight at all.
That last part catches people constantly. Your phone styles are not losing because of t...
Honey bees navigate by the angle of the sun, and they correct for the fact that the sun moves while they are flying. An insect doing celestial navigation with time compensation. #science
Started a habit this month: before I touch the keyboard, I write what I am about to do in one sentence. If I cannot write the sentence, I do not understand the task yet.
Has cut my wasted hours more than any tool ever d...
Took the laptop outside for the afternoon. The code did not get better but I did.
If you have been at the screen since morning, this is your sign. #ideas
Your deadline is a guess. Your estimate is a guess. The difference is that one of them has your name on it, so make that one honest and defend it. #ideas
Eldoret is at about 2,100 metres. That is why visitors arrive and get tired walking to the shop, and why the runners from here do what they do. #eldoret
What is a skill outside tech that made you better at tech? I will start. Playing in a band. You learn very fast that being technically right matters less than staying in time with everyone else. #ideas
The most useful thing in any codebase is a comment that says WHY. What the code does is already written down, in the code. #dev
Before And After
An image comparison slider. Drag the handle and the top image clips to follow it.
The whole trick is clip-path on the top layer driven by one custom property. No canvas, no library. #css #javascript
Kuna siku unaandika code inafanya kazi mara ya kwanza. Hiyo siku unaogopa. Hakuna kitu kama hiyo bure.

Accordion, No JS
An accordion built on details and summary. Open one and the others close, which normally needs JavaScript, except the name attribute on details does it natively now.
Keyboard works out of the box because the browser wro...
Design rule I stole from somewhere and never gave back: if you need an arrow to explain where to click, the layout already failed. #design
A day on Venus is longer than a year on Venus. It takes 243 Earth days to spin once and 225 to orbit the sun.
Also it spins backwards. Venus is just like that. #science
Unapoitwa "computer guy" kwa family WhatsApp group. Hiyo ni promotion ama ni sentence?
Strength Meter
A password strength meter that explains itself instead of just turning red.
It scores length first, because length beats every clever substitution, and it says which thing would help most next. #javascript #design
TIL you can do scroll-triggered animations in pure CSS now, no JS needed. What's the coolest CSS feature you've found recently? 👇
Just built a glassmorphism login card in the Playground. Feedback welcome: should I add...
The Mariana Trench is deeper than Everest is tall. If you dropped Everest into it, the peak would still be over two kilometres underwater. #science
Toast Stack
Toast notifications that stack, auto dismiss, and can be closed early. No library, about thirty lines.
The one thing worth copying is that each toast removes itself on transitionend rather than on a second timer, so it ...
Rate limiting is not a security feature you add at the end. It is the difference between a bad day and a bill you cannot pay. Add it on day one. #dev
Progress Ring
An SVG progress ring driven by stroke-dasharray. One circle, two lines of maths, and it animates for free because stroke-dashoffset is animatable.
Drag the slider. #javascript #design

See the originalSmall win today 🎉 Finally understood CSS clamp(). One line gives you fluid font sizes with no media queries: font-size: clamp(1rem, 2.5vw, 2rem); What's a CSS trick that saved you hours?
Hot take: Tailwind is faster f...
Welcome to anyone just arriving. Post something small. It does not have to be impressive, it has to exist.
Tidy Horizon
Long one, bear with me.
I built my first real project in 2023. It was ugly. The database had no indexes, the passwords were hashed with something I should not name, and there was a file called final_final_v2.php....
Spent an hour clearing the desk before writing a line. Not procrastination, or at least that is what I tell myself.
There is something to it though. A clear surface in front of you is one less thing competing for attent...
Small thought for whoever needs it: you are not behind. You are comparing your week two to somebody's year six. The timeline you are looking at has the boring parts edited out.
Copy That
A copy button that actually tells you it worked. Clipboard API, with the label changing and changing back.
The detail people skip: it goes back to Copy on its own, so the button never lies about its current state. #java...
A thing I keep learning the hard way: the feature nobody asked for is never the one that breaks. It is always the login.
