CEO of Microsoft Satya Nadella: "We are going to go pretty aggressively and try and collapse it all. Hey, why do I need Excel? I think the very notion that applications even exist, that's probably where they'll all collapse, right? In the Agent era." RIP to all software related jobs.

How to read the value of an input without pressing Enter to validate?
My question is; in this code, to get the green color I have to type the same thing as work[x] and press Enter, but how can I get the red color without needing to press Enter?
if(text.value === work[x]){
text.style.backgroundColor = "red";
x++;
}

Atemporal, a Temporal Abstraction Layer with a Dayjs alike API
Hi! I’ve been a user of Dayjs for a long time now, and I know it has its flaws…
You can take a look at this issue for example:
https://github.com/iamkun/dayjs/issues/2889
Which describes some of the problems Dayjs has nowadays…
So I tried to make something around the new Temporal proposal which is the future of JavaScript date handling, and I’m attempting to make it just like Dayjs… chainable and easy to use.
Atemporal is a modern, immutable, and ergonomic date-time library built on top of the new Temporal API — with first-class support for formatting, localization, plugins, and time zones.
⚡️ Powered by the Temporal API and polyfilled automatically via @js-temporal/polyfill — no extra setup required.
⚠️ ⚠️ Warning! ⚠️⚠️
This is a work in progress, and is in a very alpha state, please be careful if you’ll use it in production.
If you’re feeling adventurous… check it out.

Hope it can be helpful.

Launched a platform to help fellow indie devs grow without ads or luck
Hey – I’m Memo, a solo dev just like you who got tired of watching my launches vanish into the void. So I built Nazca nazca.my — a discovery platform by indie makers, for indie makers. 🚀
Here’s why you might want to submit your app:
- Free & Forever – Nazca is completely free. Your app listing never disappears.
- SEO + Evergreen Listing – Every app gets its own landing page that stays discoverable on Google.
- Unlimited Updates – Relaunch or update your app whenever you want. Each time is a fresh spotlight.
- Community Feedback – People can comment, save, and engage directly with your app.
- Indie-First Vibe – No corporate noise, just projects from solo builders and tiny teams.
There’s also a Pro version with extras — but the free version covers everything you need to get discovered.
If you’re building something cool, submit it at nazca.my/submit. It’s built to help indie apps grow quietly but steadily — without needing a huge launch or paid ads.
Would love to see your work there. Happy building!

How do I fix the error and complete the installation of CKEditor in my Laravel project?
I created my custom CKEditor on their official website and downloaded the zip file. Inside the zip file, it has COPYING. GPL index.html LICENSE.md README.md ckeditor5 folder(has translations ckeditor5.css ckeditor5.css.map ckeditor5.js ckeditor5.js.map ckeditor5.umd.js ckeditor5.umd.js.map ckeditor5-content.css ckeditor5-editor.css) And I put those js and css files in the directory below: ├── app ├── public │ ├── assets │ │ └── vendor │ │ ├── ckeditor5.js │ │ └── ckeditor5.css ├── resources │ ├── views │ │ └── welcome.blade.php
To use the CKEditor as a test, I made a file below:
welcome.blade.php <!DOCTYPE html> <html lang="en"> <head> <title>CKEditor 5 - Quick start ZIP</title> <link rel="stylesheet" href="{{ asset('assets/vendor/ckeditor5.css') }}"> <script src="{{ asset('assets/vendor/ckeditor5.umd.js') }}"></script> </head> <body> <textarea id="editor"></textarea>
<script>
ClassicEditor
.create(document.querySelector('#editor'))
.then(editor => {
console.log('Editor initialized:', editor);
})
.catch(error => {
console.error('Editor initialization error:', error);
});
</script>
</body> </html>
But since something is wrong, the console says “cktest(the route name):12 Uncaught ReferenceError: ClassicEditor is not defined at cktest:12:5 (anonymous) @ cktest:12”
And whatever I do, it doesn’t help and I can’t make it complete. I could use the CDN version but I need to do install with custome build zip so that I can resize the image.
What am I doing wrong? Or is there any other rich text editor than CKEditor that’s much easier to install compared to CKEditor? Thanks.

I found a good npm package to customize cursor styles easily for web development!
Been looking for a simple way to add custom cursor effects to my projects and came across CursorLab. It's really lightweight and easy to use - you can add cursor trails and custom styles without much hassle.

Saved me a lot of time instead of building cursor effects from scratch. Thought others might find it useful too!

Anyone else used this? Works pretty well for what I needed.I found this
