Clearly making a motor with induced magnetic fields both for the stator and rotor isn't the innovation here, since a large fraction of industrial motors do not have permanent magnets.

I would assume the innovation here would need to be making it small and efficient for any meaningful torque output? Usually when you see claims of a 93% efficient electrical motor its the result of taking an absolute beast of a 2kW machine and operating it at 400W. Does anyone have insights into what Renault are doing here?

KeePass is just an encrypted database file with UI around it for usability. You can keep the db on a USB drive, sync it through a cloud storage, e-mail it to yourself, whatever ... It's really not that complicated. BitWarden is the above as a service, I reckon.

Nb. The above refers to KeePassX. No idea what the KeePass without the x is about. Naming things. So hard.

I figured 2x4 would be the theoretical minimum since ascii characters are 1 byte each (without extensions). 1x5 with color is impressive, even if it is sort of like a faux 3x5

After the transition to digital TV our broadcasted signals mostly look like noise, though. Maybe an outside observer would assume that our civilization ended sometime in 2010.

I'm half expecting to see "AI model" appearing as stand-in for "linear regression" at this point in the cycle.

Wait, does that mean that you could make an ASCII representation of a QR code that points to the URL that the QR code was made of?

Shouldn't 523 in that list of "other numbers" actually be 522?

> I wrote my first line of code in 1983. I was seven years old, typing BASIC into a machine that had less processing power than the chip in your washing machine

I think there may be a counterpoint hiding in plain sight here: back in 1983 the washing machine didn't have a chip in it. Now there are more low-level embedded CPUs and microcontrollers to develop for than before, but maybe it's all the same now. Unfathomable levels of abstraction, uniformly applied by language models?

The opposite of down is up, so it wouldn't be completely illogical.

Indeed, 15 or 25 mph (24 or 40 km/h) are the speed limits in school zones (when in effect) in CA, for reference. But depending on the general movement and density and category of pedestrians around the road it could be practically reckless to drive that fast (or slow).

It does sound like a good outcome for automation. Though I suppose an investigation into the matter would arguably have to look at whether a competent human driver would be driving at 17mph (27km/h) under those circumstances to begin with, rather than just comparing the relative reaction speeds, taking the hazardous situation for granted.

What I would like to see is a full-scale vehicle simulator where humans are tested against virtual scenarios that faithfully recreate autonomous driving accidents to see how "most people" would have acted in the minutes leading up to the event as well as the accident itself

Indeed, then this design will truly have come full circle.

I remember the pitch for Julia early on being matlab-like syntax, C-like performance. When I've heard Julia mentioned more recently, the main feature that gets highlighted is multiple-dispatch.

I think it seems pretty interesting.

Even with text, parsing content in 2D seems to be a challenge for every LLM I have interacted with. Try getting a chatbot to make an ascii-art circle with a specific radius and you'll see what I mean.

I think the selfishness here is related to being fine with generating a pile of electronic waste that becomes a problem for everyone else, as long as he can avoid carrying a few ounces extra.

It's hard to recycle electronics, because separating materials that are chemically bonded together is very labor intensive and isn't worth it from the price of aluminum, copper, lithium, etc alone.

It would have to cost more to dispose of a laptop for this to work out financially.

In 15 years: Testing shows that automotive shaped charge glassbreakers can't penetrate the armor on most modern automotive glass.

Was drone-proofing civilian cars a mistake?

I wish there was an active dev community that could patch win10 going forward, but without access to source code for the kernel, perhaps that isn't really viable.

Ideally I would want to use Linux but I also want to play games that are only supported on windows.

Does using WSL help or is an outdated windows base still going to be the weakest link in the security onion?
