I made a thing! It's a tool to measure finger strength, you can use it figure out how much force you put into a hangboard in grip positions you can't hang with. In the video I explain how you can make your own, alternatively if you don't like watching videos you can just read the README on my github repo (https://github.com/Jan-de-Munck/scale) and follow the instructions from there

Big companies: “We have money and a roadmap”

Indie creators: “We have… Well, roadmap is actually a fiction. We have open-source tools and we need to survive.” 🌿🔥

Big budgets ≠ big vision.

The future of creativity isn’t owned by corporations — it’s built by artists 🎥✨

Art isn’t about who spends more. It’s about who’s brave enough to walk into the wilderness where limits are just a fuel.

To studios: Adapt or fade. To creators: Your time is now.

Okay so a guy in my solid state physics class was telling us about this muon scanning startup he worked at, GScan, and I'm going insane. I don't work there and I have no stake in the company, financial or otherwise, I just need to tell you about it.

Muons are short-lived subatomic particles, same charge as an electron but ~200 times more massive. On Earth, they're produced by cosmic rays colliding with the upper atmosphere, and they hit the ground at a rate of about ten thousand per minute per square meter.

They're moving extremely fast at ground level, like 0.99 c. So they careen right through matter, deflecting only very slightly around heavy atomic nuclei – they'll penetrate like a hundred meters into solid rock.

What do you do with this continuous shower of deep-penetrating charged particles, constantly blanketing every square inch of the Earth's surface?

(source)

The classic thing is use them to image the inside of massive structures, like we use x-rays to look inside living tissue – except instead of generating them yourself, you just use atmospheric muons. Muon archeology is a whole thing, they've used it to find hidden chambers in pyramids and stuff. Neat!

But this one Estonian company is doing some crazy bullshit and I love it.

Sandwich anything between a pair of portable muon detectors and get full 3D imaging of the interior, with sub-millimeter accuracy, by tracking the minute deflection of muons between them. Samples that are WAY too thick for x-rays, made of literally anything. Just put some muon detectors on some two by fours in a warehouse and call it a day.

You can just. Image anything??? Anything you want?? Completely passively!! Just detectors! No particle source! Put them anywhere. The detectors themselves are a mature technology, the company's tech is in the algorithms they use to get this level of spatial and elemental resolution.

You can detect failures inside cable-reinforced concrete bridges without cutting open the bridges.

Decommissioned Soviet nuclear submarine filled with concrete, with no drawings or documentation, that may or may not have spent fuel canisters in it? And you need to cut it up for storage? Just look at the muons.

One of the wackiest ideas is to put one detector under your bed and one on the ceiling, so you get a full 3D scan of your body every night, passively. I want one.

The Rise of Arduino Compatible Boards - An Exploration of the Expanding Ecosystem

The Genesis of an Open Source Movement When Arduino was launched in 2005, it helped spawn the age of accessible, affordable microcontroller boards and platforms. By providing a common hardware and software standard that was simple to use but still powerful, Arduino opened the door for non-engineers and electronic hobbyists to easily create interactive projects and prototypes. This drastically lowered the barrier to entry for physical computing and embedded systems. Within a few years, the Arduino platform had grown into a thriving global community with developers of all skill levels sharing code, tutorials, and ideas. The Growing Demand Inspires New Options As Arduino gained popularity and demand increased, companies recognized an opportunity to expand the ecosystem. Rather than competing directly with Arduino, many started releasing boards that were compatible with the Arduino software and libraries. These clones and derivatives allowed users to benefit from Arduino's openness while also having alternative hardware options at lower price points or with additional features. Some boards were nearly identical clones while others incorporated unique enhancements. Regardless, their compatibility with the Arduino IDE gave users the flexibility to choose a board that best fit their specific needs and budgets. A Proliferation of Board Types and Form Factors Today, the variety of Arduino Compatible boards available is staggering. In addition to the classic Uno and Nano form factors, there are boards shaped as mini PCs, single-board computers, wearables, educational kits, drones, robots, and more. Each brings something new while still maintaining the foundational principles that make Arduino great. For example, some focus on size and portability while others emphasize power, connectivity, or cost. Educational boards make learning to code more interactive and hands-on. Industrial boards enable Arduino to be used in professional contexts that require certifications or rigorous testing. A World of Enhancements Beyond the Original Spec Many Arduino compatible boards one-up the original Arduino specs by including features like WiFi, Bluetooth, GPS, high-speed microprocessors, more memory and flash storage, additional input/output pins, and specialized sensors. Some push processing power to the level of Raspberry Pi while shrinking the board size. Others add compatibility for new languages beyond just C/C++. Interfaces like Ethernet, USB, and add-on shields expand what these boards can interface with. Many also supply dev kits with components, sensors, motors and displays to simplify prototyping of specific project types. Get more insights on Arduino Compatible

A few years ago I had a phase of being REALLY into digital privacy, using tor, duckduckgo, etc before suffering some burnout because I was trying to be 100% secure. So I'm by no means a expert I'm just relaying experience.

The culture of a lot of left leaning and "fandommy" sites (tumblr, twitter, etc) tends to fear/dislike (or just not know about) a lot of the IT stuff used by people into online privacy because they asscoiate it with "techbros". ESPECIALLY anything even remotely involving cryptocurrency. But if Trump is going to start censoring things and making morning after pills harder to get now might be a VERY good time for Americans to get into online privacy and how to avoid being tracked as well as avoiding censorship. Perhaps even some crypto to buy things discretly (or perhaps if ICE agents start caring about cash?) and because many activists groups also take donations in crypto. Never dealt with crypto myself but from what I know Monero was designed to be more untracable than Bitcoin. Don't know how succesfull that is though. Definetly get into privacy in general though.

I'll leave some useful links to get started. Words of advice:

Don't install a fuckton of privacy extensions on your browser, your unique combination of extensions will give your browser a unique fingerprint. Instead read up on and pick a few commonly used ones.

The BIGGEST annoyance for me was acedemic/proffesional settings because noone wants to switch over to some software they never heard off for one group project. Personally I use some normie software for exclusivly proffesional purposes with NO other information on me and do my actual browsing/leisure computer use more privatly.

https://www.privacytools.io/os: General software/browser/etc recomendations.

https://coveryourtracks.eff.org/: Test how private your browser is.

https://www.torproject.org/: THE gold standard for privacy focused browsers. Also obscures ip. Might not always be practical. Has the disadvantage of being notoriously slow and is blocked by some services/websites to avoid people bypassing ip bans and whatnot. Probably don't use this as your everyday browser but if you ever need to look up anything without censorship use tor.

https://tails.net/: Install a portable mini operating system on a usb stick to browse privately from any computer.

https://www.eff.org/ Electronic frontier foundations website.

https://mastodon.social/explore Don't have experience with it myself. But open source social media that should be much harder to censor.

Tumblr probably won't like me talking too directly about this because of ties to piracy but for people interested in banned books https://en.wikipedia.org/wiki/Shadow_library should be an interesting read...
