In the last year Google has banned: the Element app, the LBRY app, and several Fediverse apps. If you get all of your apps from a single corporation, be it Google or Apple, you should make an effort to change that.

If you have an Android phone F-Droid is an alternative app repository, and it’s very easy to install! All of the previously mentioned apps have been available from F-Droid throughout being dropped from the Play Store.

If you have an iPhone, please consider other options for your next device. Apple does not respect you enough as a user to consider you possibly more capable of deciding what you should install on your phone than they are. That is absurd; please stop rewarding this behavior with your money.

Man I wish the American economy still had small stores like this... Radioshack put them all out of business then stopped selling it when places like digikey put THEM out of business.. now you can only order from a catalog and its just not as satisfying.

I am seeing more and more people on various social platforms finally realize what a cancer Python is.

Me, a glorious embedded C programmer, who knew all along.

Might make a bike computer or add this to a set of garden sensors I made previously. These displays look great in full sunlight.

Set about playing with a cheapo e-paper display over the weekend. Waveshare has some great code for use with the STM32 that I adapted for use with STM32CubeIDE.

I could have chosen a better test image, though...

Set about talking to some WS2812 addressable LEDs over the weekend and made this demo up. There's a sheet of paper in front of the LEDs to make the colors more pronounced.
The processor is a cheap STM32F401 board which sends the whole string of all 7 LED colors to its PWM timer over DMA.
Colors are advanced every 10 ms. Every 1 ms, the colors are blended by a weighted average to smooth out the effect. Overall, the LEDs look like they update at 100 Hz.

Hi, @freemo. Any plan to support webm/video uploads on the server? I've been looking to upload some clips of projects.

An explanation I gave a while back as to why gun statistics generally favor the fact that less restrictive gun laws means fewer violence and homicides.

I basically explain why the typical argument of "countries with more guns have more violence" is inherently anti-scientific as it violates fundamental statistical analysis good practices. Instead we would use statistical causality tests for this, not correlation tests. When we actually look at the data from that perspective it generally shows that countries with less restrictive gun laws effectively lowers a nations homicide and violent crime rates.

Reattached the graphs from that post, but best to click the link to the original post where I go into more detail (the graphs are there as well).

Can someone teach boomers how to use source code management without checking in gigs of binaries, IDE preferences, and configuration files?

I wanted to share a write up I did not to long ago explaining circuit duals with a specific focus on magnetic circuits. They behave the same as an electric circuit in the sense that anything you can do with an electric circuit there is an equivalent way to do it with a magnetic circuit. A magnetic circuit is a circuit that uses the magnetic fields propagating through “wires” rather than electric fields. It’s a very cool idea and worth a read, though all the usual electric concepts are flipped, for example instead of talking about electromotive force (EMF/voltage) you would use magnetomotive force instead (MMF) as filling the same function as voltage in an electric circuit.

Let me know what you think, this tutorial was a week long effort to write.
