Don't buy cheap plasticky Chinese copies. Buy Czech Merkur instead: https://merkurtoys.cz/ Merkur is about as old as Meccano and Erector and boys from the former Eastern Bloc are most likely very familiar with it.

That's why many cars include also a radar that detects and alerts you of approaching traffic from the sides before it comes into view - both camera and the driver (the blind spots when reversing are large). E.g. Mazda 3 has that - if i

The set of parking sensors costs what? 100 USD? On a car that sells for upwards of $30-40k? That's a pretty ridiculous penny pinching.

Drone at 40000 feet? That's higher than most airliners - that would need be one heck of a drone, especially given where they have shot it down and how far it would have had to fly. Much more likely sounding/meteorological balloons

And it just so happens that most meteorological payloads tend to be cylindrical/small boxes. So it is possible that trigger-happy NORAD is shooting down a lot of perfectly harmless stuff now.

You realize it is Sunday, right? And that probably a lot of relevant people are not in the office today, even if the techops grunts who are on call are scrambling.

If you don't automate, don't document and don't check that it is actually working your process from the get-go it is only your own fault, especially when working on industrial scale like this. Rotating the certificates consta

I have just received the "You are over the daily limit of sending tweets" message. Sent three (!) tweets today. Couldn't think of a better way to kill the user retention and engagement. Well done, Twitter!

I think this says more about the Google interview process than about ChatGPT. That a machine learning model can "bullshit" its way through an interview that is heavily leaning on recall of memorized techniques, algorithms and &quo

No questions but thanks to all of you guys. That's one heck fascinating stuff you are working on there and big kudos for researching and documenting the tech history! I remember seeing this Globus device in all Russian spaceflight phot

What you are saying is correct from an engineering standpoint but it completely ignores the human psychology. Tube amps produce a lot of (not only harmonic) distortion, especially the cheap stuff. And then there are also various nonlinearit

It won't. Federation doesn't solve any of the problems Twitter now has. That instead of one poorly managed understaffed silo full of trolls and abusers you have 2000 poorly managed, even more understaffed systems with 2000 differe

Except he has fired exactly those. Like the entire information security team. Giving Twitter your payment/CC info now is likely a very bad idea ...

That's likely the flight simulator application causing it, not the VR headset. Those things are extremely performance intensive even without VR, with VR it gets only that much worse. Unless the application & the setup is very high

If you were unable to focus your eyes properly afterwards it means the headset you have tried has been likely poorly adjusted and/or damaged. Typically the interocular distance was likely set incorrectly for you (there is a slider on t

12 to 17" 4k monitor is completely pointless. At those sizes a normal FullHD or 1920x1200 panel will do you the same service - and cost much less and require much less powerful GPU to drive (battery of your laptop will thank you!)

That's all fine and groovy - as long as your work doesn't involve any text or anything requiring high resolution/fine details. Then unless you spend $$$ for very high end hardware with high resolution (4k on a headset != 4k o

Don't do that. That's a good way to turn an annoyance into a very expensive failure to fix (and, of course, no warranty anymore). Superglue or epoxy on an inductor is going to prevent the inductor from having sufficient cooling. A

Yeah, do that and you may cause the power converter to overheat and die because the superglued inductor may not get enough airflow over it anymore. These wonderful "fixes" (along with people "reflowing" stuff using heat

If it is truly a "coil whine" and not something else (case resonance, fan bearing whine, high pitched noise from the speakers, etc.), then you can't fix it. The noise is caused by one of the many inductors in the various powe

He means that the average gamer that isn't gaming in 4k at 120Hz and/or going crazy with a high end VR rig (these things are still a tiny minority comparatively) will not fully utilize even the capabilities of the current hardware

Sorry and how many people actually have 8k displays to begin with? Or have a monitor that is actually capable of those 240Hz refresh rates? Better graphics sells games, no doubt. But there is also a tradeoff between investing huge amounts o

Nvidia doesn't think so simply because you are a tiny niche that has such "requirements" - and also the money to burn for it. Don't get me wrong, there is nothing wrong with it - just you are simply not the market that i

That's a bit missing the point of what he said. You are correct about the hardware requirements - but his point was that 90% of the applications of this high end hardware ends up being in machine learning (and or crypto mining) and not
