Cool links of the week

I collect cool, interesting links spread all over the web and share them here every Thursday. Hope you enjoy! More of them in the archive.

My favorite mouse costs less than USD 10. Who needs a MX Master?

Ductts. A diary for crying and tears. For iOS.

Baseline. A nice theme for Obsidian.

Just Buy Nothing. A fake online store to scratch that shopping itch. According to the creator of the site, “this is either the dumbest idea of all time or something that will actually help people stop giving their money to these corporations that are actively trying to make their sites as addicting as possible while the quality goes down and prices go up…” Tip from Rafael.

Compare Small Form Factor PC Cases. Shows the size and volume of various computers.

“Break glass in case of emergency,” Liquid glass edition. If you enable some accessibility options, macOS 26 “Tahoe” looks like a 1990s OS.

Windows XP-themed Crocs, The Verge. The missing merch from Microsoft’s 50th anniversary celebrations. As expensive (USD 80) as it is ugly.

Term-Shdw. A small application that creates a “comet effect” for the mouse cursor inside the terminal.

Subtitle Edit. Video subtitle editor. Free, for Windows.

I spent 6 years building a ridiculous wooden pixel display. Through the kiloxp.com site you can interact with the display and there’s a live stream of it changing on YouTube.

Threadbare. “Story-driven, collaborative game where players don’t just explore a world—they co-create it.” Still in development, Linux only.

NextDNS gains feature to bypass age verification, r/nextdns.

“Meta AI, what app do you recommend for private messaging?”

A friendly introduction to SVG. Drawing on web pages with code. Who would have thought?

A partial comparison of window management interactions in iPadOS 18 and 26. Maybe it was harder to discover these gestures in iPadOS 18, but it seems like a better thought-out thing (and better overall) than the version 26 implementation.

F-Droid Search Metrics. Statistics from F-Droid, the Android app store from an ideal world.

Cheat Sheets. Repository of quick references for various technologies. Tip from Alexandre.

Known bug in NetBSD’s sleep command, via @ayke@hachyderm.io. The command can’t handle durations longer than 250 billion years. If necessary, put the command in a loop, with each command limited to about 200 billion years.

Delete old emails and pictures as data centres require vast amounts of water to cool their systems.

— UK’s Department for Environment, Food and Rural Affairs.

The absurd guidance is part of a list published by the UK government to mitigate the severe drought affecting England, alongside useless classics (“take shorter showers”) and other nonsense (“use water from the kitchen to water your plants”).

As David Gerard pointed out, the document makes no mention of the inefficiencies of (privatized) water companies nor the thirsty data centers focused on artificial intelligence. (The great irony is that the suggestion to delete emails to save water may have come from generative AI. Is this how AI will end humanity?)

My favorite mouse costs less than USD 10

Anyone looking for a new mouse usually stumble upon the Logitech MX Master at the top of recommendation lists (MSRP: USD 99). The one I use daily costs a fraction of that, or 1/10 to be exact. Are they worth what they cost?

Old people on the internet probably remember phpBB, a discussion board software that was very popular in the early 2000s. I discovered, by chance, that it still exists and has active development, albeit slow: the phpBB3 series was released in December 2007 and the last major update (3.3), in January 2020. If it ain’t broke, don’t fix it…?

Cool links of the week

Web browsers with AI assistants built-in are coming. Are they the future of browsing the web?

Tiny Awards 2025 opens voting. Runs until September 1st.

eightyeightthirty. A site that collects links from those 88×31 pixel badges and puts them in a web visualization. (Site is a bit heavy.)

“linux” on DuckDuckGo. DDG’s mascot, a duck, becomes a penguin when you search for “linux.”

Time Flies. “A little adventure
about our limited time in this world.” For PlayStation 5, Nintendo Switch, Windows and macOS.

Web browsers with AI assistants built-in are coming

Just as the US justice decides whether Google will have to divest its web browser, Chrome, a new generation of rivals emerges, bringing built-in artificial intelligence “assistants” as their differentiator.

It’s quite likely a coincidence, but it’s still curious. There are several asterisks to this story, starting with the fact that these new rivals are built on top of Chrome’s foundation, Chromium. I’ll set those asterisks aside, though, because the more important question is whether these assistants are here to stay.

FinTech Dystopia. A web-published book by Hilary Allen about “Silicon Valley ruining things.”

Chemicals on the seafloor sustain an extreme-depth ecosystem (video). Life exists at almost 10 km deep.

Wplace. The world is a coloring canvas. Reminds me of those Reddit events.

StoryTerra. Explore movies, series, books and games by location and/or date on a big map. Behind the scenes.

Instaloader. A command-line tool to download Instagram content, even stories (requires logging in with an account, though).

A less affectionate approach to technology

It’s almost impossible to escape WhatsApp and very difficult to get rid of Instagram. For many, it’s also undesirable. Friends, relatives, loved ones, and the entire presence of many businesses are only available on one or the other (or both).

In 2022, when I wrote about a “more affectionate approach” to technology (pt_BR), I had recently returned to using these and other commercial platforms. I lowered my defenses in an attempt to be more present, to participate more.

The problem with companies like Meta is that every concession on our part is exploited to the fullest.

LookAway Mirror. LookAway, the nice macOS app that reminds you to take breaks during the day, got an iOS companion that blocks sites and apps when the computer is also locked.

Pebble is called Pebble again. They got the trademark back.

Spiral Getty. A Wikipedia-based visual search tool.

This option disables Meta AI and increases privacy in WhatsApp conversations

Remember when WhatsApp was just a lightweight messaging app? I miss those days. Today there are so many features, so many announcements of new stuff that sometimes useful ones slip by unnoticed.

By chance, the other day I came across “Advanced chat privacy,” available in group and individual conversations. It was released in April.

When activated, three things happen:

  • It disables conversation export. This makes it harder to forward messages to third parties and process them with external AIs, like Google’s NotebookLM.
  • It disables automatic media downloads.
  • Finally, it disables access to Meta AI, Meta’s annoying AI that, by default, can be invoked by typing @meta in a conversation.

Unfortunately (but not surprisingly), there isn’t a global button to activate advanced privacy in all conversations; only within each conversation’s options.

Given the impossibility of using a better app, like Signal, it’s a good option to activate when sensitive topics are being discussed.
