OP is talking about 1900 miles, which is some 3050 km or 27.5° across Earth. One can see more than 150° of the night sky in open areas so one will see over 80% of the stars the other does.

I agree that a list would be cool but I need to make sure that people know this is not a “WARNING! Avoid these bugged devices:” situation. Calling for a list increases unjustified panic. (Also, it looked like you didn’t understand the difficulties of listing all ESP32 products, which I was all too happy to be pedantic about.)

Am I oddly curious about the cheapest/most expensive/most popular retail ESP32 device? Yes.

Does this news increase/decrease the benefit of making such a list? No, it’s still way below the cost.

No. I’m saying you cannot have a complete list because the chip is user friendly. Look at all the “ESP32 project” results in the search engine of your choice if you want an incomplete list. Unlike say an Intel processor, you don’t need a contract with the manufacturer to make a device with the chip so not even Espressif has a list of commercial products that ship with their chip.

I will not stop you from building a list, I’d just not bother if I were you. There is no use of one resulting from this news. Suppose I told you “LOOK! This device’s firmware was compiled before they knew the program might be .1% more efficient with this instruction discovered in 2025!” – would that really change how you feel about the device? We live in an age of bloat; most software has way higher overhead that could be optimized away.

However, lots of people will fail to realize that, again, this is not an exploit so I’ll enjoy lower ESP32 prices for future home automation projects.

I hate people who blame the Mercator projection without properly learning about what is wrong with it.

1. This is not a Mercator projection map. The northern side of the US is straight and horizontal on Mercartor maps.
2. “Straight lines” on a globe (great circles) on the Northern hemisphere bend in this ⏜ way, not this ⏝ on a Mercartor map.
3. Flattening a sphere without compromises is impossible. Most other projections are either unusable in many local contexts or don’t span the globe. Mercator (specifically the WGS-84 implementation) works very well unless your journey goes over ±84° latitude, which is OK for most cases. Every other projection will stretch, skew or cut local areas in major ways and EVERY ONE WILL SHOW (almost every instance of) THE SHORTEST (great circle) PATH AS NOT STRAIGHT. And the last, all-caps point only manifests for long journeys. If you can travel long distances in a straight line, you are piloting a ship or aircraft, and you can afford a computer to plot the great circle curve.

Actual problems with Mercator:

1. It needs to be infinitely tall to cover poles. This map shows how tall a version that gets to .1 mm from the South Pole is. Therefore, polar researchers and the military need to get another app for navigation (along with hardware for whatever the substitute for GPS is).
2. It significantly distorts sizes at different latitudes so it’s not recommended for showing the entire world, especially for a child’s first impression. There are worse picks, such as Gall-Peters (which preserves sizes but stretches shapes horribly unless you are close to the very conveniently picked 45° latitude where most of the Europe lives, nullifying the notion that the map combats imperiallism) or Dymaxion (which I love but cutting oceans and the equator into incongruent pieces strewn all over the page does not help children grasp basic geography).

That’s like saying “I want a list of all devices with ATmega328P.” Anyone can make a unique device with this chip as the processor, in fact I have. It’s a chip with an extremely low barrier of entry thanks to extensive documentation, lots of dev boards and libraries. Not as low as the 555 (lots of people’s first IC) but WAY lower than anything you’d traditionally consider a 32-bit CPU.

Anyway, even if you obtained the list magically, it would be of little use. To be clear: this is not an exploit. The chip just has more instructions than previously thought – instructions that you write into your program when building an ESP32 device. This can make some programs a little faster or smaller but you still need to flash them onto the microcontroller – using physical access, OTA (if you set it up in the existing FW) or some exploit (in someone’s OTA implementation, perhaps).

There is nothing to “fix”. Undocumented instructions have just been found in the silicon but they are not executable unless the ESP32’s firmware their owner flashed to give it a purpose uses them. No pre-2025 firmware that we know of uses these instructions, and they might turn out to be buggy so compilers might not adopt them. If they turn out OK, the documentation of the instruction set will need an update, and compilers will be able to take advantage of the new instructions.

Yes, this is about undocumented instructions found in the silicon but they are not executable unless the ESP32’s firmware uses them. Firmware cannot be edited to use them unless you have an existing vulnerability such as physical access or insecure OTA in existing firmware (as far as researchers know).

It is good to question the “backdoor” allegations - maybe the instructions’ microcode was buggy and they didn’t want to release it.

This is about silicon. Undocumented instructions have just been found in it but they are not executable unless the ESP32’s firmware uses them. Firmware cannot be edited to use them unless you have an existing vulnerability such as physical access or insecure OTA in existing firmware (as far as researchers know).

Comes with a heartened announcement before the show from the theater manager: “I KNOW ALL THE QUOTES, YOU KNOW ALL THE QUOTES, NOBODY WANTS TO HEAR YOU AND YOUR FRIENDS QUOTE THE WHOLE MOVIE, SO SHUT UP AND JUST WATCH!”

I mean, if it’s the most traditional form you’re aiming for, the Finns in certain regions/seasons might have historically had more access to ice than fresh water

Maybe ice is simply more available than liquid potable water in Finland.

That’s a fairy

cubed Water

Ice blocks??

Trying out Blorp (the newly out-of-beta Lemmy app) and it looks great!

Please reupload, Imgur is bloat

My wireless headphones just cracked open and you wouldn’t believe what was inside!! Fuck you, you ruined the magic!

It’s a fucked-up world where literal nazis are in the left half of the spectrum. This is why I’ve deliberately fried my exocortex (rip In-Tulpa) and fled the Biocon Soldier training grounds to become a Hiveist. I have ADHD and a severe lack of dopamine and I know joining the Hive will help us both; I want nothing more than to donate my compute to get The Uniting Fog finished sooner.

Biocon Priest’s In-Tulpa is an angel. You know, an innocent little boy.
