⚙ So exciting! Look at all those atoms! ⚛

I don't know what these things are called but I roughly know how they work and it was fun to play with! Of course a CFL bulb in my hand lights up thanks to the HF HV electric field.

Good night Fedi :3

Study of thousands of players shows a simple online game works like a “vaccine”, increasing skepticism of fake news by giving people a “weak dose” of the methods behind disinformation.

“This is a version of what psychologists call ‘inoculation theory’, with our game working like a psychological vaccination.”

The game itself is apparently hugged to death: https://getbadnews.com

Igorrr - ieuD is such a masterpiece

This could make an awesome AND terrifying science-fiction story.

I wonder if it's possible that an artificial satellite orbiting Venus would have remained invisible to this day. If it has a small enough radar cross-section and stable orbit...

I wish I would know more astronomy.

How fucked up would it be to find ruins of a highly technological civilization on Venus?

Venus is totally in the habitable zone (although it has very long days) and the only reason it's so hot is because its dense CO2-rich atmosphere. What if once it had sentient life and they started a runaway global warming...?

First class cars on an otherwise full train is a crime against society.

Democracy is a lot like ecosystems. People take them for granted. We can often think that they're is resilient enough to protect themselves.
They're also hard to grasp and quantify. And there are circumstances in which they just destroy themselves.

I had to notice that it runs quite warm, 70 degrees Celsius according to the thermal camera. That's a temperature rise of 45 K over ambient.

I hope it will work as expected, and help me be more productive while I'm travelling.

For circuit design and layouting I really need two screens; especially with the shitty 1366x768 resolution thinkpad... Maybe I should do the fullHD mod.

I took it apart and now I know; it uses the LM2576, so from USB it runs at near 100% duty cycle which it really didn't like. It is probably intended to run from 12-14V.

It only had 20uF input capacitor, which is not enough with 5-ish volts coming out from USB (meaning higher current for the same power) so I added 200uF extra, and now it runs stable! I can either power it from my laptop or from a power bank.

I'll share a photo of it later in action.

A while ago I found a tiny (7"?) display in Elen's old room, which I used since then when I needed to look at misbehaving servers, very useful.

I thought it would be nice to use it as a secondary monitor with my laptop, but it didn't run well when powered from USB. Since it lacks any kind of documentation or part number, I had no idea what the "DC in" port really means...
