Can confirm, radar signal processing is very bandwidth heavy and not suited to a typical CPU.

Can also confirm that it is generally regarded as impolite to talk too much about it!

Radar is cheap now, thanks to semiconductors getting smaller and faster the analog front-end which used to be a long expensive chain of components is now much smaller, the ADC is now faster, more accurate, and cheaper, the processor is now fast enough to keep up with a higher bandwidth signal. You could probably drive a very rough radar system directly off a Pico's GPIO and ADC, maybe toss in a decently fast op-amp for a receive amplifier.

Where you will run into issues is processing radar signals into usable data. If you're happy with the results that radar was giving 30 years ago then it's fine and dandy, but the magic of modern radar is in the software, not the hardware.

Wow! You managed to break almost every financial law and regulation in one go. That's amazing!

I feel like it would be unfair to make them include the SVG decoder, the artical uses TypeScript and I believe that is a feature most runtimes (browsers) provide. However they do have to include the SVG files themselves. The Canadian flag from Wikimedia comes in at 699 bytes and France at 262 bytes. So I'm fairly confident that even with compression they'll be over 5kB

Yes, it does. I can't speak universally but I would generally expect it to be a written rule, if not then at least it's the expectation.

We should probably assume that the authors are aware of ceramics, Curie points, and the earth magnetic field. While the article isn't very clear on what effect causes the change in temperature needed to erase the VRM. I suspect is has something to do with how long the object has spent stationary with respect to the earth's field. At least that's my takeaway from having to periodically rotate magnetometers to prevent them from acquiring a bias.

StimDeck, for autism on the go.

AI inference is basically 1 operation iterated over every single model weight. That's what's makes computer in memory attractive and feasible.

General purpose workloads would require much more silicon real estate and are not (typically) nearly as bandwidth hungry. Just like not all CPU workloads benefit from being adapted to a GPU, even fewer will benefit from being adapted to processing in RAM.

The signature doesn't touch the image data in any way. It's just a piece of metadata attached to the image, like any other metadata tag.

They did, they contracted with a vendor to store and backup the data. If that is insufficient then just about every customer of AWS, Azure, GCP, OCP, and every other managed storage provider is guilty of the same sin.

As a whole, I'd say it's for better. Obviously Nine PBS's situation is shitty and fuck "OSS" for putting them in that position, but they are not Iron Mountains customer. They are strangers to Iron Mountain who just demanded 50TB of customers data from Iron Mountain. The only sane response is to tell Nine PBS to come back with a court order, and (hopefully) to tell their lawyers to just make sure Nine PBS is in fact the rightful owner and if so, not to fight them on it.

Anything else is the sort of stuff that causes blog posts and news articles about data breaches to be written.

You and crtasm both make an excellent point about where the problem lies. I suffered from a critical imagination failure by never considering the implications of running the link on anything other then a controlled and isolated network.

They do not care, AlphaTheta is well down the enshittification road. They captured all the DJs, then they captured all the venues, and now they'll squeeze both for profits until a sufficient critical mass has built to trigger a collective switch away from them. At which point executive bonuses will be paid, investors will get their returns, and the PioneerDJ brand will be sold to an even scummier company to wring a few more dollars out of it.

I too also have a special place of hate for Rekordbox. However I'm somewhat confused by this vulnerability, isn't plug n play unauthenticated file access essentially a core feature of "PRO DJ LINK"? The security mitigation, and best practice, being to have the involved devices connected on a entirely private LAN. I've never tried connecting them to a "public" network.

That's why most platforms have been forced to adopt non-DMCA takedown procedures (available only to large corporations of course). This way they are able to get rid of "infringing" content without the responsibilities or accountability of a DMCA notice. And of course without having to provide any rights to the original poster.

I like to remember that Gibson wrote Neuromancer on a typewriter and hadn't even touched a computer till (I believe) half way through Count Zero.

> The hard part seems to be smooth rapid vertical descent. It's impossible to predict how the prop wash will interact with the wind and push the drone around as it descends into its own turbulence. I was tracking betaflight development for a while and was wondering if we'd ever see some kind of prop-wash calibration. Is there some adjustment of PID gains while descending through prop wash that could improve stability?

The phenomenon is called Vortex Ring State* and it's not a problem that can be solved with a better calibration/control. A basic description of the problem is the prop moves into it's own prop-wash replacing happy lift with sad turbulence. The solutions are to:

1. Don't descend vertically, always have a reasonable degree of lateral motion. 2. Descend vertically slowly, how slow is vehicle specific 3. Angle the propellers so that their thrust angle is off vertical. 4. Descend with no power at all, thus avoiding the creation of prop-wash entirely, halting the descent will require the use of 1-3.

If you do happen upon a solution that can be applied to traditional helicopters there's probably a good deal of money in it for you.

Oh yeah, there's no shortage of reasons not to use SF6. Even in conventional waveguides, as far as I know most designs these days prefer nitrogen or dried atmospheric air.

You don't need a significant flow of argon, just enough to keep unwanted gasses out of the waveguide.

It's possible there exists a material that is transparent to mm waves, airtight, and can survive the conditions at the bottom of the hole. In such a case they could cap the waveguide and prevent any gas leakage.

I'm quite sure Quaise is well aware that Argon isn't cheap and are already exploring multiple avenues for reducing its usage.

It is interesting that they have to use Argon instead of the more typical Nitrogen or SF6. A waveguide with such a significant pressure differential is decidedly unusual and a unique challenger for what they are doing.

Nobody is questioning the value of unconstrained mass surveillance on solving crimes.

Unfortunately it also enables a good deal of more heinous crimes against the people its supposed to protect, by the people who are supposed to be protecting them.

Its not integrated to the SoC, it is soldered to the mainboard though.

They didn't have the code for the offensive program, they were creating the emulator to run it on a different architecture.

The user wants the website to work in IE6, developing and testing only against IE6 to the detriment of other browsers is not generally regarded as a healthy state of affairs.

The standard exists, it is the responsibility of both the producer and consumer of ePUB files to adhere to the standard.

Yes, for the ones I've owned rooting is very easy. KOReader and Plato are both popular (amongst the community of eReader rooting people) alternatives to the OEM software.

Whether or not it works isn't what matters. It's whether or not the perpetrator, consciously or not, believes it works.

I feel like building an nLab would be a far more valuable learning experience then using one.

The caveat being not just as a DIY soldering kit but as a full "course" in the design and construction of it.

Its got a power supply, an MCU, analog I/O, digital I/O. Learning the theory of how to read a 100kHz analog signal is far more valuable then a device that can read a 100 kHz signal.

They're presenting it as a "intro to electronics" device. I think they've missed though, as far as I'm concerned, learning to build a "nLab" equivalent device from a bare AVR MCU would be a far more informative and useful introduction then yet another "Babies First blink.c" kit.

Even worse, a fully formed lesson plan, parts, and prerecorded lessons could actually be worth $200. Unlike this widget, which is not worth half that.

The spec page says 100 kHz BW on the oscilloscope, the FAQ says 400 kHz. In either case calling it an "oscilloscope" is a stretch, its the ADC channels on an MCU.

I find it curious that all their promo shots seem to only show the back of the board. I couldnt find any of the component side, or any information about what components are used. My guess would be:

- a very small dual rail supply

- AVR or STM MCU

- Signal generator is PWM through an RC low pass filter

- Oscilloscope is potentially just the input through a resistor network to shift +/- 5V to 0-5V, maybe a buffer to keep input impedance high.

I just don't see $170-200 of value here, or anything close to that.

A company operating above board would be sure to carefully document the state of the rental before and after whatever work they were doing. Any tradesperson/installer/technician/repair person will have tales of how they were accused of stealing grandmas wedding ring from the bottom of the sock drawer while repairing a leak in the kitchen.

So either Bot Company damaged property and is trying to pretend they didn't. Or they are incompetent and failed to document the state of the property or handle the owners complaints appropriately.

Given that their training robots and would therefore be collecting as much data as possible, including camera data, I'm leaning towards malice instead of ignorance.

Of course its an incentive, however the disincentives to purchasing (subscribing/spending), and thus producing, such games still exist.
