Great post from Jean-Luc Aufranc up on CNX Software.
I usually think of open-source hardware and/or software are enabling skilled people to more easily fix bugs, improve on the design, get feedback from the community, etc…
But in a world where IoT devices become more prevalent, there’s another reason why you should request open-source software: Long term support. What made me think about are two things. The first one if that I own WeLoop Hey 3S smartwatch, which I love and wear since March 2018. That’s quite a feat since most cheap devices I own often only last a few months or a year or so. I’m also used to the watch face and Weloop app interface.

The NYC Pride theme for 2021 is “The Fight Continues”
NYC Pride announces the official theme for 2021, “The Fight Continues,” as the kick-off to this year’s events and programming. In a time of tremendous adversity for the community on many fronts, “The Fight Continues” reflects the multitude of battles we’ve been fighting as a country and as a city. With the coronavirus pandemic still ongoing, issues of police brutality, the alarming murder rate for trans POC, economic hardship, climate disasters, violent efforts to disenfranchise voters, our rights as a community being questioned at the level of the Supreme Court, and more, we are in the midst of many different fights.
Author Nicholson Baker says it’s possible that Covid-19 might have leaked out of a lab. He says it’s not a conspiracy theory, but a theory that is worthy of more research to determine how the virus came to infect humans.

Immigrant Heritage Month is an opportunity to celebrate the richness and diversity immigration brings to the United States. Every Tuesday in June on the Adafruit blog we are going to share interesting stories and awesome people that uplift immigrant heritage.
Every June we celebrate Immigrant Heritage Month locally and nationally. It is a time for people across the United States to explore their own heritage and #CelebrateImmigrants and the diversity that forms the unique American experience. For Philadelphia, it is also a time to celebrate all that is beautiful and vibrant about being a welcoming city and celebrating our local diversity and culture in all its shapes and forms.
One of the remarkable things about America is that nearly all of our families originally came from someplace else. Immigration is part of the DNA of this great nation. It’s a source of our strength and something we all can take pride in. That’s why during Immigrant Heritage Month, we are encouraging you to share your American story.
The Catalan time system is the traditional way to tell time in Catalan. Exclusive to the language, they divide it in fractions of a quarter and half a quarter of an hour.
In Catalan time is read a bit differently than in most other languages. At 00:00, is twelve o’clock, but after that time is not said as “amount of time that passed or that is missing until the next hour”, but as “fraction of the current hour (which by english standard will be the next one)”.

With a MIDI library available for the Raspberry Pi Pico making a little MIDI “piano” is relatively easy. The MacroPad which I build last month is the perfect little device to play around with this.
If you want to follow along exactly, first you’ll have to build my MacroPad, though pretty much any Raspberry Pi Pico with a few buttons attached will do. Just make sure to update the code below so that the pins correspond with your hardware.
The Raspberry Pi Pico will need to run CircuitPython for this to work, my MacroPad already had this.
Definitely guilty of giving up on stained clothes too quickly. Super handy video from NPR on YouTube.
You’ve wiped ink on your sleeve. Or dribbled dressing down your shirt. (Oil stains are the worst!) Perhaps it’s the catastrophic red wine spill on a friend’s tablecloth. Don’t fret! With the help of some common household products (dish soap, hydrogen peroxide, and rubbing alcohol) and chemistry know-how, you can be a stain removal master. This video shows you how to tackle stains like ink and blood, plus how to get oil stains out of clothes and a red wine removal trick that doubles as a great party trick.
As it turns out, quantum entangled drums aren’t going to make your electronica band big anywhere. But if they’re super tiny, they might just help boost the speed of a computer network. Here’s more from Gizmodo:
They achieved this perfect unison of drums using a quantum mechanics phenomenon known as entanglement—and the drums could be useful for developing quantum computers.
The two drums play together with a precision far beyond what an orchestra or two matching metronomes can achieve. “They essentially become one entity,” said physicist Shlomi Kotler of the Hebrew University of Jerusalem, who performed the experiment while working at the National Institute of Standards and Technology in Boulder, Colorado.Kotler’s team published their work in the journal Science this month.

Samuel Lee was an American physician and diver. He was the first Asian American man to win an Olympic gold medal for the United States (the second Asian American to win a gold medal overall) and the first man to win back-to-back gold medals in Olympic platform diving. Via LA Times
Sammy Lee learned to dive at Pasadena’s Brookside Park pool, which until 1940 allowed people of color to use the facilities only on Wednesdays, the day before it was drained and refilled. His most reliable place to work out was waterless — a diving board installed over a sand pit he dug in his coach’s backyard.
The inescapable racism “inspired me to perform,” Lee, the son of Korean immigrants, once said. “I was angered, but I was going to prove that in America, I could do anything.”
Lee overcame discrimination to become the first Asian American to win an Olympic medal and the first diver to win back-to-back gold medals in two different Olympics — in London in 1948 and Helsinki in 1952.
A retired doctor who also coached Olympians, Lee died in Newport Beach [in 2016] after suffering from pneumonia. He was 96.

In 1841, Dr. William W. Wolf moved to Dayton to practice homeopathy, a branch of alternative medicine that believes in the healing power of food. Hailed Dayton’s “Cracker King,” Wolf concocted the Wolf Cracker, a curious hard-butter snack made for medicinal purposes.
“In the 19th century, crackers were linked to Christian physiology and sectarian medical practitioners,” says Lisa Haushofer, a senior research associate at the University of Zurich’s Institute for Biomedical Ethics and History of Medicine. “Christian physiologists like Sylvester Graham, of Graham Cracker fame, were concerned about a modern diet that contained too many stimulating substances.” (In addition to being a cracker evangelist, Graham was also a pro-temperance Presbyterian minister who preached a vegetarian diet). Wolf echoed Graham’s concerns that food was far too rousing (though Graham also dubiously believed his crackers could cure licentiousness), so he launched the Wolf Cracker Bakery to churn out his wholesome snacks.

Ohio’s vaccination rate was slowing, until Republican Governor Mike DeWine started his Vax-a-Million lottery, offering a chance to win a million dollars, or a scholarship. That’s led to a 45% increase in people getting vaccinated in the state. But some Republicans are pushing back on Governor DeWine’s initiative, introducing anti-vaxx legislation and decrying it a waste. “The real waste,” says DeWine, “the tragic waste -- is when you lose someone to Covid.”

Finding organic molecules, or their organic salt remnants, is essential in NASA’s search for life on other worlds. But this is a challenging task on the surface of Mars, where billions of years of radiation have erased or broken apart organic matter. Like an archeologist digging up pieces of pottery, Curiosity collects Martian soil and rocks, which may contain tiny chunks of organic compounds, and then SAM and other instruments identify their chemical structure.
Using data that Curiosity beams down to Earth, scientists like Lewis and his team try to piece together these broken organic pieces. Their goal is to infer what type of larger molecules they may once have belonged to and what those molecules could reveal about the ancient environment and potential biology on Mars.

As it turns out, radioactivity is rare in the ocean. When naturally occurring radiation is present, it may mean an earthquake is coming. Here’s more from MOTHERBOARD:
On land, increased seismic activity is known to release small quantities of radon, a naturally occurring radioactive gas, into soil in the days before earthquakes happen. So detecting a spike in radioactivity in the sea floor might be able to help us predict underwater earthquakes. Except, as with lots of ocean science, we have almost no idea what’s going on with radioactivity on the seafloor, and to be able to detect a spike in radioactivity, we’d need to have baseline readings.
“Radioactivity itself is largely unknown in the marine environment, despite its importance” said Professor Theo J. Mertzimekis at the University of Athens. He’s leading a team with funding from the EU to develop underwater drones that can measure marine radioactivity. The 4 year project just started this spring. The team are currently very much still in labs on dry land, developing the sensors and A.I. the drones will need to operate.
