Will There Be Justice for Shireen Abu Akleh?

It’s been 3 weeks since Palestinian-American journalist Shireen Abu Akleh was shot dead while reporting on an Israeli raid in the occupied West Bank. And yet, two central questions remain: Will anyone be held accountable for killing her? And shouldn’t the U.S. be investigating the killing of one of its citizens? Lina Abu Akleh, Shireen’s niece, joins Mehdi to discuss.

Losing: DeSantis-Trump law defeated in new free speech case

Florida Gov. Ron DeSantis has been attacking Americans’ First Amendment freedoms through laws punishing views he opposes and trying to mandate what social media companies publish. An appeals court ruled his social media law violates the First Amendment and illegally tried to push his viewpoints. MSNBC Chief Legal Correspondent Ari Melber reports on the setback, and how DeSantis has used big government power to target speech while claiming the opposite.

Creating a Petabyte HD Array Controlled by a Single Raspberry Pi

Well here’s a Pi project you thought you’d never see. Jeff Geerling created a storage array of 60 20TB hard drives, aka over a petabyte, controlled by a Raspberry Pi 4.

It was just an experiment to see if the Pi had what it took (and to have an excuse to use one of 45Drive’s Storinator XL 60-bay server).

So, did it work? Sorta. Kinda. At least in a proof-of-concept sort of way.

The Importance of Early Sound Exposure in the Womb

MIT shares how the auditory system is shaped in the womb.

In the new study, the researchers showed that exposing a computational model of the human auditory system to a full range of frequencies from the beginning led to worse generalization performance on tasks that require absorbing information over longer periods of time — for example, identifying emotions from a voice clip. From the applied perspective, the findings suggest that babies born prematurely may benefit from being exposed to lower-frequency sounds rather than the full spectrum of frequencies that they now hear in neonatal intensive care units, the researchers say.

Scientists Discover That the Human Brain Works in 11 Dimensions

And you already thought the human brain was staggering complex. According to scientists working at the Blue Brain Project in Switzerland, it’s even more complex than we thought.

When stimulated, virtual neurons would form a clique, with each neuron connected to another in such a way that a specific geometric object would be formed. A large number of neurons would add more dimensions, which in some cases went up to 11. The structures would organize around a high-dimensional hole the researchers called a “cavity”. After the brain processed the information, the clique and cavity vanished.

The researcher Ran Levi detailed how this process is working:

“The appearance of high-dimensional cavities when the brain is processing information means that the neurons in the network react to stimuli in an extremely organized manner. It is as if the brain reacts to a stimulus by building then razing a tower of multi-dimensional blocks, starting with rods (1D), then planks (2D), then cubes (3D), and then more complex geometries with 4D, 5D, etc. The progression of activity through the brain resembles a multi-dimensional sandcastle that materializes out of the sand and then disintegrates.”

The significance of the discovery lies in allowing us greater understanding into “one of the fundamental mysteries of neuroscience – the link between the structure of the brain and how it processes information,” elaborated Kathryn Hess in an interview with Newsweek.

The scientists look to use algebraic topography to study the role of “plasticity” which is the process of strengthening and weakening of neural connections when stimulated – a key component in how our brains learn. They see further application of their findings in studying human intelligence and formation of memories.

New Products 5/25/2022 Feat. Pogo Pin Probe Clip – 2×5 1.27mm Pitch SWD!

Browse through all that’s new here!

NEW PRODUCTS THIS WEEK

RP-SMA to w.FL / MHF3 / IPEX3 Adapter: Most antennas have SMA or RP-SMA connectors on them, how are you going to connect them to your little RF module? This little cable will bridge the two!

This adapter cable is super handy for anyone doing RF work with modules that have w.FL connectors. It has a tiny MHF3/ IPEX3 / wFL / w.FL connector on the end – not a uFL connector – on one end, and an RP-SMA plug on the other.

Surface Mount Rotary Encoder – EC11J: For projects that need a rotary encoder but need to keep it single-sided or need to avoid interrupting traces or devices on the other side, here’s an all-SMT rotary encoder! It’s a high-quality 30-detents encoder from Alps, with detents and a nice feel. There’s a nice smooth bushing for placement in a box.

Pogo Pin Probe Clip – 6 Pins with 2.54mm / 0.1″ Pitch: The Pogo Pin Probe Clip with 6 pins in a 2.54 / 0.1″ pitch spacing is a great way to test and connect with pin-point accuracy without soldering! It’s sort of like an alligator clip with an array of built-in springy pogo pins – so you can connect to a PCB with classic 0.1″ spaced pad holes, without soldering or a special adapter cable.

Pogo Pin Probe Clip – 2×5 1.27mm Pitch SWD: The Pogo Pin Probe Clip with 2×5 0.05″ pitch SWD spacing is a great way to test and connect with pin-point accuracy without soldering! It’s sort of like an alligator clip with an array of built-in springy pogo pins – so you can connect to a PCB with classic ‘SWD’ pad holes, without soldering or a special adapter cable.

Chiharu Shiota: Using String to Draw in Space #ArtTuesday

Chiharu Shiota uses string to represent life and relationships. Learn more about Chiharu Shiota’s history, life and work in this video from Louisiana Channel on vimeo:

Strings, which now have become a signature for the artist, were her escape from the canvas: “I started to make three-dimensional pictures with strings.” Feeling more connected to the string as a material than paint, Shiota started doing performance and installation art. “I create in space,” she says about her method and continues: “When you weave string, it’s a communication with the space. It’s like painting a picture in the air.” Often the strings are intertwined but also connected to human objects such as shoes, suitcases, and old photographs that she finds at flea markets and antique shops.

Building The Bronx at the New York Transit Museum’s Grand Central Terminal Gallery

One of the most important facets of a city is it’s public transportation system. Learn all about transit and the only borough on the continent from the New York Transit Museum’s Grand Central Terminal Gallery, via Gothamist:

Before City Island voted to become part of New York City in 1895, and before it was consolidated into the Bronx in 1898, the area relied on a horse-drawn railroad — a trolley car that rode on rails and was pulled by horses — to connect to the Bartow station of the Harlem River and Port Chester Railroad. But the Interborough Rapid Transit Company (IRT), which built New York’s first subway line in 1904, was focused on using newer technologies to improve commutes.

So around the same time they were building the subway in Manhattan, the IRT took over this Bronx railway, which was called the Pelham Park and City Island Railroad. A few years later, they decided to substitute the horse railroad for NYC’s first monorail. The Flying Lady — so called because of its “long, cigar-shaped yellow car” — could fit 40 people, and took only a few minutes between stops instead of the 40-plus minutes by horse. More than 100 people came out for its inaugural ride on July 16th, 1910.

Things did not go well.

Testing for the Best Folding EDC Knives

In this Project Farm video, Todd tests out 15 brands of everyday carry folding knives: Fallkniven, Benchmade, Gerber, Victorinox, Kershaw, Cold Steel, Kizer, CRKT Fossil, Leatherman Skeletool, Milwaukee, DeWalt, COAST, Kingmax, Vulcan, Master USA.

In the end, the expensive Benchmade ($170) performed best, but the Kizer ($69) and Kershaw ($87) also showed impressive performance.

The surprise was the Kingmax (at only $13). It performed decently and includes other useful features, like a window break and seat belt cutter.

Comparing Diorama Builds That Took 1, 10, and 100 Hours

Martina of NerdForge wanted to know just how radically different the results might be in building a fantasy house diorama that took 1 hr, 10 hrs, and 100 hrs.

As you might imagine, the 100-hour diorama is amazing and the clear winner, but the results on the 10-hour house are pretty decent, too.

The 1-hr house? You can’t really complete a fantasy house diorama in an hour. She did manage to get it built, but barely had time to splash on some paint.

NASA’s InSight Rover Downed by Dust #SpaceSaturday

After more than three years on Mars, NASA’s InSight mission may come to an end. Here’s more from MOTHERBOARD:

Just weeks after the lander’s seismometer recorded a magnitude 5 “marsquake”—the biggest earthquake ever detected on another planet—mission operators announced that dust buildup on the mission’s solar panels is slowly starving InSight of power. Unless the lander is graced by a fortuitous dust devil that blows some of the crud off the panels, InSight will end its science operations this summer and will be officially dead by the end of the year.

The Weird Chemistry in This Space Rock Suggests it Came from a Super Nova

From Gizmodo:

In 1996, a rock from space was found in southwestern Egypt’s Great Sand Sea. The rock was odd, even by extraterrestrial standards, and a team of researchers studying the rock’s chemistry now propose that it came from a supernova—the brilliant, explosive collapse of a star.

The rock is named Hypatia, after a 4th-century Egyptian mathematician. Based on the pattern of 15 elements in a 3-gram sample of the stone, a team of researchers suspects Hypatia came from well beyond our stellar neighborhood, and emerged from the gas and dusty detritus that followed a distant star’s explosion. Their research is published in the journal Icarus.

The researchers think Hypatia came from a Type Ia supernova; these supernovae occur when white dwarves (the small, dense remnants of stars) consume so much material, often from a neighboring star, that they explode. That distinguishes Typa Ia from Type II supernovae, in which a large star’s core collapses, causing a massive explosion.

Read the rest.
