..."In his newsletter today, retired entrepreneur Bill Southworth tallied the times #Trump has grabbed #headlines to distract people from larger stories, starting the tally with how Trump’s posts about Peanut the Squirrel the day before the election swept like a brushfire across the right-wing #media ecosystem and then into the mainstream. In early 2025, Southworth notes, as the media began to dig into the dramatic restructuring of the fe"...

Diagnosed with leukemia, Jay Taylor thought his life insurance would protect his family. But when he tried to claim his “accelerated-death benefit,” he hit a maze of restrictions. “For an insurance company, these claims are a game of numbers. But for a family in my position, it’s the difference between financial survival and catastrophe.”

I have been thinking for a while about the issue of anonymity in Web3 (and, more in general, anonymous transactions). The growing realization of the damage caused by decentralized financial technologies is nagging my cypherpunk self, who has been at war for a lifetime against invasive tracking, manipulative marketing, and surveillance capitalism. I collected my thoughts here: gagliardoni.net/#20250427_priv…
Spoiler alert: I'm not endorsing backdoors, but I think some middleground solution must be found.

The image shows a screen displaying the "UK Audience Vote" results for a competition, likely a music contest. The list is ranked from 1 to 12, with Malta in first place, Israel in twelfth place, and the other countries in between. The countries listed are Malta, Greece, Latvia, Finland, Albania, Estonia, Sweden, Lithuania, Poland, and Israel. The background of the screen is dark, with the text and numbers in bright colors, making them stand out. On the right side of the image, there is a person wearing a black shirt with silver embellishments, holding their head with both hands, possibly in a moment of emotion or reaction to the results. The person is wearing a bracelet on their left wrist. The overall atmosphere suggests a significant moment in the event, possibly a reaction to the audience's voting results.

Determine Fundamental Constants with LEDs and a Multimeter
There are (probably) less than two dozen fundemental constants that define the physics of our universe. Determining the value of them might seem like the sort of thing for large, well funded University labs, but many can be determined to reasonable accuracy on the benchtop, as [Marb’s Lab] proves with this experiment to find the value of Planck’s Constant.
[Marv’s Lab] setup is on a nice PCB that uses a rotary switch to select between 5 LEDs of different wavelengths, with banana plugs for the multi-meter so he can perform a linear regression on the relation between energy and frequency to find the constant. He’s also thoughtfully put connectors in place for current measurement, so the volt-current relationship of the LEDs can be characterized in a second experiment. Overall, this is a piece of kit that would not be out of place in any high school or undergraduate physics lab.
To use this to determine Planck’s constant, you need to use Planck’s relation for the energy of a photon:
E = hf
Get some Energies (E), get some energies (f), and bam! You can generate a value for h, Planck’s constant. The energies? Well, that’s a very easy measurement, but it requires some understanding of how LEDs work. [Marb] is simply measuring the voltage needed to just barely light the LED of a given frequency. (For frequency, he’s relying on the LED datasheets.) That translates to the energy of the photon because it corresponds to the energy (in electron volts) required to jump electrons over the bandgap of the semiconductor in the LED– that’s how the light is generated. Those photons will have the energy of the gap, in theory.
In practice, the LEDs do not emit perfectly monochromatic light; there’s a normal distribution centered on the color they’re “supposed” to be, but it is fairly tight. That’s probably why is able to [Marv] get to within 5% of the canonical value, which is better than we’d expect.
This isn’t the first time we’ve determined plank’s constant; it’s quite possible to get to much higher accuracy. The last time we featured this particular technique, the error was 11%.
