Cool Links

Here’s a collection of interesting links I’ve found around the web. The feed updates frequently, and I compile everything into a blog post on the last day of each month.

I shrunk down into an M5 chip , by Marques Brownlee

Cool Link
2025-12-29
#tech

I usually love these videos that deal with the scale of things, and getting one from MKBHD was a surprise for sure, but a welcome one.

It’s incredible how far technology has come, and it’s a testament of how humans can achieve incredible things when we want to.

The birth & death of search engine optimization , by Xe Iaso

Cool Link
2025-11-24
#tech #ai

This article walks through how the concept of SEO (Search Engine Optimization) was born, how it inevitably became broken and how easy it is to “win” it, as long as your content is made up and not actual real information.

This Mastodon thread is an amazing tale about game development, physics and time-traveling bugs.

Introducing SlopStop: Community-driven AI slop detection , by Kagi Search

Cool Link
2025-11-16
#tech #ai #app

This is a really cool initiative! Kagi has been my search engine of choice for over a year and I’m really happy with how they’re aiming to stop AI slop from taking over their (still great) search results.

In my experience, their results are miles ahead of Google’s, Bing’s or whatever other search engine out there, partly because of their algorithm prioritizes good sites, partly because they allow you to prioritize/deprioritize/block the sites you want.

But a good algorithm only goes so far and with the amount of AI slop hitting the web every day, it’s gonna be harder and harder to avoid them. Now Kagi users can report certain articles as AI-generated so other users can know that beforehand and not click on them, or even block their domains.

Edit Photo , by Pintura Labs

Okay, this is pretty cool. This lil’ website allows you to do quick image edits right on your browser. Nothing new there - except for the fact that it actually works with no account, no ads, no popups, no upsell. Truly a marvel!

Another cool little web utility. This one lets you squoosh your image files to greatly reduce their file size without any significant loss in quality. Especially useful if you have a website of your own and want to optimize your images.

A cartoonist's review of AI art , by The Oatmeal

A really fun web comic of an artist explaining his thoughts about AI art. I think I agree with all the points there.

Notebook Navigator - Modern File Explorer for Obsidian , by Johan Sandberg

Cool Link
2025-10-09
#tech

This is beautiful. This Obsidian plugin completely overhauls the file navigation and makes it actually usable. It fixes one of the app’s biggest problems for me: navigation.

You can add custom icons to folders as well, which I used to need a separate plugin for.

Are people’s bosses really making them use AI tools? , by Andy Bell

Cool Link
2025-08-28
#ai #tech

Time and time again, we’ve been seeing companies that go all-in on AI in hopes of not falling behind or standing out while the bubble doesn’t burst. This article has some real life testimonies of employees that are being forced to use AI in their work - even if it makes things harder and makes the results worse.

Obsidian Bases

Cool Link
2025-08-27
#tech

Obsidian, my note-taking, second-brain, CMS app just got a huge feature: Notion-like databases, here simply called Bases. You can use them with any files in your vault and in my initial testing, it’s pretty powerful!

I’m already using it to manage Cool Links, and looking forward to use it for more of my stuff in the future.

uBlock Origin Lite for (iOS) Safari

Cool Link
2025-08-10
#tech

Finally! I’ve been using uBlock Origin on my desktop browsers since it’s existed, and it makes the commercial web usable. Now it’s finally available for iOS Safari (maybe on the Mac too?)

Safari has had some ad blockers for a while, but none were as good as this one. This one blocks ads, trackers, and even allows hiding some page elements you select, just like the desktop version.

A must-have in all my web browsers.

Como eu salvo links e preservo conteúdos no mundo pós-Pocket , by Augusto Campos

Cool Link
2025-07-27

This article (in Brazilian Portuguese) was a huge inspiration to me in reworking how I save my Cool Links, starting this month. I’m using the Obsidian Web Clipper instead of the custom solution the author had, but the principles are still the same.

Building up a weekly routine to organize things has also been a good change, as I don’t have a lot to do at the end of the month when I’m putting this post together.

The Internet Used to Be a Place , by Sarah Davis Baker

#deep-read #tech

Amazing video about the internet we’ve lost (or rather, was taken from us), and how we can rebuild it.

Absolute fan of Sarah’s storytelling here, the way she weaves through the topics and links (hah!) them to that Hypnospace game is amazing!

Don't Guess My Language , by Robert Vitonsky

Cool Link
2025-05-31
#tech

As a bilingual person that’s soon moving to another country I really struggle with websites and apps that keep trying to serve you content in a specific language instead of the one you choose. Google is one of the worst in this regard.

Even worse is when the content is translated automatically. It sucks! Google again sucks at this. It keeps reverting things to Portuguese and even re-enabling automatic dubbing (gross, I know) on videos, even though I explicitly have my device, browser, and Google account set to English.

Kagi Search Stats

Cool Link
2025-05-31
#tech

Kagi has been my search engine of choice for over a year now, and I just found out about their public stats page. Pretty cool they have this info open out there!

The most interesting part is the Domain Insights, that ranks the domains that get most blocked/prioritized on Kagi (Kagi allows you to prioritize results from specific domains, or simply block some altogether). It seems people really hate getting Pinterest results 😅

Moving from Notion to Obsidian , by Dave Rupert

Cool Link
2025-05-31
#tech

I love Obsidian, and have been using it for over a year for taking notes about everything. The thing about his kind of app though is that you’re always looking for ways to tweak and improve your system. This article is great at explaining how Dave uses Obsidian for himself and as usual has a list of neat plugins.

One day, maybe, I’ll write my own post about how I use it. I’m just not confident enough on my system yet, probably…

Test Ad Block - Toolz

If you use any adblockers (you should!), this website is a neat way to test how effective your setup is. The higher, the better, but if you get a green result you should already feel safe browsing online. I got 98% with my NextDNS + UBlock Origin combo!

The Everything App is a symptom of Nothing Management

Cool Link
2025-05-31
#tech

This is a spot on overview of how pretty much every tech company now has no clear direction besides making more money. No vision, no goals, no passion, except for making the number go up.

Yea, every company needs to make money because workers need money to survive, but when a system only ever rewards those that seek money above everything else, that system has failed and will continue to fail unless a big shift happens.

The passionate, skilled, full-of-ideas people that could solve real problems and/or improve the lives of others have been crushed by the weight of big companies looking for one more way to exploit you.

The Internet Archive opt out itch , by Stefan Judis

Cool Link
2025-05-31
#tech

In this article, Stefan ponders the ethics of the Internet Archive’s opt-out behavior. The work they do is really good for the web in general — but, on an individual level, it kinda sucks that someone is archiving your website without asking?

He also raises the point that while you can ask for your website to be excluded from being archived, doing so might make you (or your company) look shady and untrustworthy. Like, what are you trying to hide so much?
