RealityVoid··on That time when I failed the Microsoft interview
The water level decreases, along with the shore and anything with it falling within the event horizon. Any other apocalyptic brain teasers?
RealityVoid··on That time when I failed the Microsoft interview
Lake level stays the same.
RealityVoid··on Prevent cognitive debt by manually retyping LLM-generated code
What do you think would be the effect on people that already have the skills and abilities. The LLM would build these systems using the skills that are largely understood by the programmer but piece them in new ways suitable for the system. This could lead to new enmergent behaviors that are not understood by the programmer.

I still think that you can build this model in your head even with LLM's but I'm not sure neither one way or the other.

RealityVoid··on The bond market isn’t buying what Fed Chair Warsh is selling
What happens to the local price of oil if you are able to export the oil at a much higher price?
RealityVoid··on It's not empowering to hand off the details
Yes, owns. Ownership as in accountability, stewardship and care. But I think you already got this from my post and if we're fighting about semantics, there's no constructive discussion to be had.
RealityVoid··on It's not empowering to hand off the details
When an employee writes a system, the employee owns the system. When an AI writes a system for you, YOU own the system.
RealityVoid··on It's not empowering to hand off the details
Tools? Yes. Reliable foundations? Eh, mostly not. Maybe I'm holding it wrong, but I'm not impressed. Not in the least because in order to get a good system you must have a good image of the system in your head. And if AI builds the system, how will you ever get that system in your head?
RealityVoid··on Design is compromise
Would you say... You have arrived at a compromise? Ba-dum-tshh!
RealityVoid··on Writing by hand is good for your brain
Yes, but that is a different kind of improvement compared to note king during a lecture as an adult. I think hadriting ability is important, I just don't think note taking dutin a lecture is useful in any way.
RealityVoid··on Writing by hand is good for your brain
Certain kinds of writing is thinking, but you're not writing in the thinking way, you're transcribing.
RealityVoid··on Writing by hand is good for your brain
Or... Hear me out... Don't take notes at all. I'm sure I can find supporting material that is just much better than my paltry notes. I find that for me, it detracts from engaging with the material. I just much better prefer to listen and engage and think what is being said.

I only take notes if I am trying to work out some of the things said or as support for this or that or maybe 2 really interesting lines or quips I want to remember just so later and I find particularly surprising or interesting (or mistaken, hah).

When solving math problems, yes, by all means take notes! I find writing with a pen indispensable because it's much more flexible and expressive. And i need the memory caching that writing provides.

RealityVoid··on Natural experiments prove phytoplankton carbon removal works
This scenario is pretty similar to the Azolla event:

https://en.wikipedia.org/wiki/Azolla_event

Where "event" in this case is something that happened over an 800 000 years interval.

RealityVoid··on My car’s OTA update broke Android Auto
> it’s a voluntary industry standard that has no government oversight or regulatory authority.

Yes, hence why I said I'm not sure about enforcement mechanisms how they stack up against the aviation standard. Still, in my limited experience, projects that are ASIL x take the thing pretty seriously and they do get certifications from external bodies. Actually, I am supporting an SEooC external certification right now.

> The infotainment system itself may be QM but there has to be assurance that it is in fact separated from higher safety level system.

The separation most likely happens _outside_ the infotainment itself, through a gateway.

RealityVoid··on My car’s OTA update broke Android Auto
> don’t have anything like the verification and documentation processes that are mandated by DO-178

ISO 26262? Not sure how the enforcement looks, but automotive is pretty serious about ISO 26262.

Still, the infotainment is most likely QM so it wouldn't apply in this specific situation.

RealityVoid··on I also filed the corners off my MacBook
They make many many many more things than just powertools. They have ebike motors, home appliances, industrial machinery, chips (they have a very good division for MEMS as far as I can tell, they make high quality IMU's, they are super popular for airbag usage), protocols (the CAN bus is BOSCH IP and you pay 1 cent royalty I think for each MCU's with CAN on them), automotive components.
RealityVoid··on The Tokio/Rayon Trap and Why Async/Await Fails Concurrency
Real time control can be like that as long as the computing parts are clearly bound within your performance requirement.
RealityVoid··on SpaceX bond worth 10% less than issue price – heading for junk bond status
Falcon rockets, starlink, Tesla. They all pushed the envelope in their field. Are the stocks overpriced? Yes. Did they do impressive technical work? Also yes. They might get surpassed by competitors, but that is to be expected for all companies. But they clearly did something special there. And I deff am no Musk fanboy, but you have to give him the credit for establishing those systems.
RealityVoid··on The kids with phones are alright
OP is from Palo Alto, so, obviously, the closest thing to a hellscape you can possibly get. /s
RealityVoid··on The kids with phones are alright
This is obviously an overstatement. Sure, a phone is convenient, but we managed to function just fine without smartphones. I assure you, it's possible to do all those things without a phone.
RealityVoid··on QuadRF can spot drones and see WiFi through my wall
Can you back this up with any authoritative sources?
RealityVoid··on QuadRF can spot drones and see WiFi through my wall
This is not a radar, only a receiver.
RealityVoid··on QuadRF can spot drones and see WiFi through my wall
According to CivDiv's channel about 70% of the drones used are still RC FPV drones. They are cheaper longer range and have a slightly simpler supply chain. Fiber optic cable prices have exploded because of the war.
RealityVoid··on The glass backbone: Why the Army's logistics will break in the next war
It's not as easy as plopping a new SW on it. Have you wondered why, despite this conflict dragging on for this long, autonomous targeting is still not common? It's just much harder to do, and doing it reliably is actually super hard.

Hw access is also not as easy as you think. Try getting a Pixel 9 class SoC board that you can actually dev stuff on, you'd be surprised how hard it is to get such a thing. And when you get it, it will probably be 2x as expensive for just the board.

Oh, put the Pixel 9 on it then. Have you tried doing optical flow on rolling shutter cameras?

Then, whatever solution you get, you need sufficient volume and reliable supply of the thing. Oh, you can't find the chip anymore? Good luck porting the stack you have since the pipeline is different.

Whereas these rc FPV drones you can basically build what what you find in the back of your drawer.

RealityVoid··on AI doesn't know how to forgive and cannot forget
It's probably doing a lot of heavy lifting.
RealityVoid··on The glass backbone: Why the Army's logistics will break in the next war
I think one way communication should be sufficient together with a shared secret. It's probably less reliable compared to two way communication, but it should satisfy the criteria. IR visual pattern propagation will respect this. You don't have radio spectrum that is too prone to jamming, and if the drones are visual navigation/targeting based, if they can see you to acquire the you as a target, they can identify you as a friend as long as you can ensure emitters are not occluded from your side.

It's not perfect, but it's cheap and it should work.

Give me a couple hundred k and I can probably build the prototype, haha.

RealityVoid··on EU Parliament greenlights Chat Control 1.0
I would have expected the right wing parties to be against this, somehow, but... Nope, just checked my country's votes, and nationalists just love cc1.0 it seems.
RealityVoid··on The glass backbone: Why the Army's logistics will break in the next war
I think you can do this relatively simply with infrared led lights. Imagine "Please don't kill me" remote controls. You are a bit more visible when broadcasting, but presumably you can be selective when turning it on.
RealityVoid··on The glass backbone: Why the Army's logistics will break in the next war
You need hardware for these things. High speed image processing and high precision control and global shutter cameras. You can't just slap a raspi on it with any run of the mill camera and call it a day.
RealityVoid··on EU Parliament greenlights Chat Control 1.0
This has an expiration date baked in for 2028 so if no new legislation comes in until then, it will undo itself on its own.
RealityVoid··on EU Parliament greenlights Chat Control 1.0
Oh, yes, thankfully the protections for privacy are much better in the US... right? Right?
