The animation is confusing...is one trip to the end and back the 1B iterations? I thought maybe they were counting up and once the slowest reached the end they would all stop but that didn't seem to be it. Maybe if it did (and there was a counter on each showing how many bounces they made), it'd be a little more clear.

Interesting nonetheless.


Looks like they are just bouncing back and forth at relative speeds to each other; the speed of each ball is all that matters. I also found this diagram confusing at first.


Not natively. There is other firmware out there, though, that allows such functionality. Depending on where you live, it may be illegal to even try, though, hence the native firmware locking out such use (you can record or visualize but not save/replay).


Just recording and replaying wouldn’t help you anyways, the code is rolling to prevent replay attacks.


I think if you have enough replays you can deconstruct the rolling code. Not sure.

Also there are ways to desync/resync your key so you might be able to “add a key” with the flipper with certain firmwares.

Cloning the current key and using it can desync it from your car. Super annoying. Be careful


I don’t know exactly how the rolling key works but wouldn’t it be kind of like having a secret stored in the key that’s needed to generate the next code? If it’s designed properly, recording a few thousand codes shouldn’t tell you anything about the next code, just like you can’t deduce private keys by looking at a few thousand encrypted files. I have no clue if that’s really how it works, so I would be happy to be corrected if my mental model is wrong here.


> If it’s designed properly,

That phrase is doing a lot of heave lifting there...

(This is only what I've read, but as i understand it many rolling code keys can be broken by recording three button presses while the keyfob is out of range of the car, then brute forcing the seed.)


Basically yeah. You'd need millions of replays to even have a chance. Cracking basic wifi back in the day required a couple days worth of sniffed packets. I'd imagine this is similar, if there is in fact a way to do it.


Rolling code protocols like Keeloq can be broken pretty easily (apparently).


Plenty of devices use the Keeloq protocol for rolling codes which is pretty straightforward to break in modern hardware.


Probably as enforceable as any other EULA. Windows surely has similar language. I'd guess that somewhere buried deep in the agreements, or somewhere, it says they can audit your usage somehow. Does it ever happen? I'd be curious to know.


Windows doesn’t have similar language. Not directly, anyway. Depending on the edition of Windows you purchase and how your overall license agreement works, you get anywhere from zero to ten VM licenses per paid Windows license.

I’m omitting a few details for brevity (MS licensing is nuts when you get into the weeds).


Wonder why it seems like all QT5 are "no help wanted"...


Qt5 is in maintenance mode. Qt6 has long been released.


Qt 5.15 at this point has been out for 4 years, already out of "normal" commercial LTS and will reach the end of extended commercial LTS next year. They don't have any incentive to do this kind of change.


Agreed. Interesting that Yahoo was your choice. I may try it as well (have experimented with DDG and Bing a bit, but haven't used Yahoo since it was the only option back in the day).


Off topic (sorry), but has the quality of searches been on a steady decline over the last year or two? If I'm not just imagining things, wonder if it is because they changed the algo or if there is too much noise for the algo to work well anymore. Frustrating nonetheless...


Yes, it's been discussed a lot in that time period how bad the decline has been.

I also use assistant a lot and it too has fallen off a cliff. Assistant in 2016 was better than it is today. Crazy.


Disregarding search results, it's been impossible for me to learn over all these years when it will actually start listening to me. Unpredictable time, can't count on the beep, can't count on the lights... it used to be instant on, and I miss that.


Google was at least super good at caching so if you knew the url you wanted a snapshot of it was almost definitely snapshotted accurately.


IF configured away from the defaults:

By relying on the default keepalive limit, NGINX prevents this type of attack. Creating additional connections to circumvent this limit exposes bad actors via standard layer 4 monitoring and alerting tools.

However, if NGINX is configured with a keepalive that is substantially higher than the default and recommended setting, the attack may deplete system resources.


They have a device/chip compatibility list here: https://github.com/OpenIPC/wiki/blob/master/en/guide-support...


In the article one of the attendants says "I hit stop on Pump 3 and nothing happens" so they are at least seeing the pump is on and running. Whatever is happening must be either locking the attendant out or is leaving the attendants machine in a bad state with the pump running switch "on" so to speak. I wonder if it's actually NFC. It'd be interesting to see what a Flipper Zero would come up with.


I can imagine a lot of Flipper Zero owners heading out to explore pumps now.


Agree, sounds like some kind of poorly-protected function has been discovered that's putting the pump into a "maintenance" or "test" mode where it will dispense fuel without a prepay having been completed.


> "Every time we push Pump Three stop, it wasn’t doing anything," he said. "We have to shut off the whole pumps - we have emergency stops."

Whew - sanity prevails! When I read the part about not stopping, I was a bit worried that the e-stop somehow was not a simple mechanical failsafe.


There are multiple mentions of "extraterrestrial super islands", is this a mistranslation of the Meissner effect? Great term nonetheless.


It's the mistranslation of room-temperature superconductivity.

"super islands" is likely translated from 超岛 which sounds the same as 超导 (superconductivity). I have no idea how 室温 (room-temperature) became extraterrestrial, must be extraordinarily bad speech to text model.

edit: could be 室温 (shi4wen1) -> shi4wai4 -> 室外(outdoors)/世外(out of this world) -> extraterrestrial


What a hilarious mistranslation. Somehow it is fitting though, as a totally unprecedented floating material.


You're exactly right on the extraterrestrial part: the speech to text transcribed it as "最近我们这个有关世外超岛的话题非常的火热"


I wish I could learn CJK. Will take a lifetime to master.


Yes, I saw that, there are some more obvious translation errors.


The extraterrestrial super island of stability


Let's break one rule at the time, please. I don't think I'm quite ready for heavy elements that are long lived, either at room temperature or any other, and even less so if they turn out to be non-radioactive...
