By coincidence I re-watched that film this weekend (I like it a lot) and seeing this article immediately made me think of it. Yes, in the film he takes meds, but he stops doing it after a while because of the side effects (impotence amongst

Very interesting! The audio of Tom's Dinner rejected by the encoding sounds mesmerizing to me. I still find it to be musical - it reminds me of a record I bought a really long time ago, it was called modulation & transformation on

It all depends on the situation. Here in the Netherlands almost everybody has an PV installation with no way other than the breaker to turn it on and off. Some inverters do have an interface, and sometimes it's available. Even less peo

Sure. Of course. Not being allowed to disconnect them would be ridiculous. But do you want to keep an eye on the market every day, and run to the breaker to turn on an off your inverter? No. So you need a solution for that. Then a battery i

Well, until '27, I'm allowed to use the grid as a free battery, basically, this is a kind of government subsidy. But that will end, and the contracts available will be fixed price with a feed in tariff or dynamic (realtime) market

It's nice to have solar panels, I have them too and while they do generate even more electricity than I need, they do so in around 6 to 7 months peaking in July. So in winter, it's grid power and in summer I might need to pay to f

The thing is though that even with array bounds checking built into the language, out of bounds access due to programming error can still be attempted. Only this time it's safer because an attacker can't use the bug (which still e

Mine as well. Sucks that I just went through the required updating of the build (minimum sdk) of my only app on there, a 2016 Java string art app below 2MB with no data collection, advertising or monetization whatsoever. Now they want to pu

On my phone, turquoise is green for me, but on my laptop it's blue. I guess that's why it's called turquoise. The same thing happens with the purple spectrum. There's an unlimited amount of purple hues, ranging from red

It doesn't. The spider's name is 'Number 16'. It could be any alphanumeric string.

There are popular embedded platforms like STM32 that don't have hardware double support, but do have hardware float support. Using double will cause software double support to be linked and slow down your firmware significantly.

Me too. I didn't even know about this blockade. I'm using T-Mobile fiber internet and rt.com loads just fine.

What a coincidence, I first saw this video in my YouTube recommends and now here. I used to have an MSX-2, a Philips. It had a double sided 720K 3.5" floppy drive, fhe file system is FAT12 and the disks were compatible with PC's.

From the article: "When we don’t feel confident in our code, it is tempting to attach our sense of self-worth and professional pride to something that can be measured. A set of strict lint rules, a naming schema, a file structure, a la

Very interesting to see this here. I bought the Nike missile control unit years ago from some guy here in the Netherlands and it still sits in my garage. It has cool mechanical gyroscopes and microwave components. I disassembled most of th

The case of what is a constant, and whether or not it even really is, is not always clear in C. As an embedded developer (almost always on bare metal), variables declared with the const modifier are usually (but not always, it depends on th

Really nice to see this here. I'm in the Netherlands and it has been a tradition in my family and my mother's family to watch this (on tv) on new year's eve. It's been quite a while since I watched it, living on my own.

I switched to Brave a few days ago and have never been happier. The problem with firefox on Android is that it is extremely slow, though apparently not for everyone. Slow in the sense of tapping a link, then having to wait 5 to 10 seconds b

The oscilloscope works like a vector display (or x-y plotter). A circle can be displayed by feeding a sinewave voltage to the Y input and a cosine to the X input. Adding a voltage to the Y input moves the ball up and down. Similarly, adding

Looks good. Simple, humble, to the point. It has a certain elegance that I like. It loads fast as well.

Just counting the bottles, soda intake in your household works out to 3350cc/day*person, on average. If you're not exaggerating, you have a very unhealthy habit.

Voltage drop is one way to look at it, but since efficiency is paramount, it's better to look at losses. Losses in the conductor are I^2 * R, so when there's a current of 3.5A, losses are 6.6W at an input of 3.5*13.4=46.9W. Effici

Allwinner (A10, etc) SoCs have it. You still need the connector with integrated magnetics though.

On some microcontrollers I know a pointer to address 0 really is just that. I tested compiling the following unsigned short *a = 0; ((void (*)(void))a)(); which may cause a jump to address 0 (usually the reset vector). On R8C w

I fondly remember a university project where we made an mp3 player - hardware based around an Intermetall (MAS) chip and the software to drive it. This was late 90's and the run of the mill 486 struggled to play 256kbps mp3's. I d

I had the same question, looked up the resolution, it's 312x390, about half VGA. Guess that's why it looked pretty sharp still. By the way "Optional: hot glue a motor to the watch’s crown to keep it from falling asleep."

I've been using my own proxies for years, just a plain SSH dynamic SSH tunnel (SOCKS). It's pretty easy to do with a cheap linux VPS. If you want, you can set up a tunnel on one local port and another one (from another VPS) on ano

Theoretically it's possible, but in practice the lower input voltage makes it harder to convert it to +5/+12V. It becomes increasingly lossy and expensive - to convert 0.5V to 12V at 10W is not trivial to begin with. Voltage acros

It would, but the size would be impractical and it's too costly. Quick estimate, let's assume we need 10W for 10 seconds, that's 100 Joule of energy. The energy stored in a capacitor is 0.5 C V^2. Say we use a 10V capacitor t
