With all the AI boom, there’s an uncomfortable β€œskill” we’ll have to train: context switching.

Devs are famously bad at it. Managers, not so much.
Now AI agents push us toward 5–10 tasks in parallel.

More productivity… or just more exhaustion? πŸ€”
Skill to train, or a well-disguised trap?

πŸ”₯πŸ₯ž Hot take: there's no such thing as "the best AI." There's the best AI for each task.

Here's my current setup:

- Gemini: API + good notifications β†’ fast in applications
- Grok: real-time updates/news
- Claude: code + agents
- ChatGPT: day-to-day + multimodal

What's your preferred combination?

Believing there's only one right way to work is a mistake.

Perhaps the best skill isn't choosing one side, but being willing to adapt when the context changes.

Saying that remote work "isn't good" is an oversimplification.

The important thing is to try both models and see what works for you.

Remote and office work have their pros and cons. And we're not static beings.

Writing my JavaScript book has been incredible: I've iterated on several things, learned and polished the content so that anyone can truly learn from scratch.

I'm already working on Part 2, but parts 0 and 1 are available on my blog.

Importing vs fetching JSON They behave differently, so make sure you pick the right one.

πŸ“ Importing vs fetching JSON

JSON imports are now supported cross-browser, but when would you use them rather than fetch()?

I was testing how the theme-color works and some hacks to make it prettier.

I leave a before and after the hack so that the header and footer look β€œinfinite”.

How does it look?

What is an Algorithm? β€’ Undefined Shell by Guillermo Rodas is your definitive source for everything related to programming and web development. At Undefined Shell, we are passionate about exploring and learning about innovative digital product development, especially in the Full-stack and JavaScript realm. We offer detailed tutorials, analysis of the latest technological trends, and practical tips for developers of all levels. Join our community passionate about web development and take your skills to the next level. β€’ Undefined Shell by Guillermo Rodas An algorithm is a set of instructions or steps that are followed to solve a problem or carry out a particular task. So, a manual for assembling a prefabricated piece of furniture or a cooking recipe could be considered algorithms.

Ever built IKEA furniture and ended up with one screw left over? πŸ™ƒ

Or watched someone twist a Rubik’s cube until suddenly everything clicks into place?

That’s what algorithms are about, following steps that look confusing until the logic reveals itself. 🧩

The problem isn't using AI to create content; the problem is that generating poor-quality content is becoming easier.

The theory of the dead internet.

Ever noticed how a yoga mat only gets dirty on the side that touches the floor?

Well, I invented the MΓΆbius Yoga Mat: the first mat that gets dirty all over, on every surface.

No wasted space.

AI can trick you into laziness, making you think it can do everything for you. But once you get past that illusion, the magic happens: you realize it actually amplifies your knowledge. πŸš€

New generations will never know the thrill of searching for something online without even knowing where to start.

Playing detective, falling into rabbit holes, discovering new ideas, and following threads to unexpected places.

It's funny how there were so many posts, demos, and interviews about GPT-5, all clearly prepared in advance for its launch today.

It feels like they knew it wouldn't be that surprising, so they needed to make some noise.

The true engineering value is to avoid unnecessary work, not to write faster code.

The less code you write, the more you get paid. πŸ’°

I’ve always felt strong in Frontend, even as a Fullstack dev.

But with everything happening in AI, I shifted a few months ago, now I’m part of an AI Infra team.

Has anyone else changed direction because of AI?

I think this is the first ad I’ve seen that uses Gen AI.

If you look closely at the details, it’s obvious.

Being a good graphic designer or illustrator is not just about drawing beautifully or applying styles.

Those who think that don't understand work.

Now, if your job is repetitive or doesn't require critical thinking, an AI will do it sooner or later.

It doesn't matter the profession.

The reality is that if you want to move up in your career, you need to go the extra mile, or someone else will and get the promotion instead.

And I’m not talking about working extra hoursβ€”you can always work smarter.
