Pardon my shitposting.

Thriving in the gap between software and hardware.

A fucking flower.

Ever heard of the game Shenzhen I/O? That WAS my day job.

For someone who has dabbled in electronics my first impression is "this is useless". Soldor wick is basically multi-stranded copper wires. You can already cut it with whatever snips you have on your bench.

But Hakko is Japanese i think? They like to release wild products. I remember Makita releasing a microwave oven and coffee maker that uses their battery and has their color scheme.

The design is pretty modern. But what is with the choice of the Kodak CCD sensor? CCD cameras got a resurgence in Chinese communities with second-hand camera prices increased like tenfold.

Also see Apertus Axiom where they also used the Zynq but used one hell of a CMOS sensor that can do 4K 300FPS.

For your second example it's impossible to find a YouTube video of Chika dance that is available in every country. Try this: https://streamable.com/0hrdh

It's remarkable how smooth the animation is. And how natural the character's movements are. This scene jumps over the uncanny valley straight into being enjoyable.

And I think there's an AI paper from a Chinese researcher using this video as a demo.

And the beautiful thing about adaptive attacks is that they look exactly like Hollywood, it's beautiful! Because you see them flipping and going through values, getting it right and moving to the next one, which you all told it was fake, it was not!

Wenext. I used it from single quantities up to a couple hundred pieces. They assign a human in the loop to check your model that you can email to.

Hard to believe it's only 50 years old because of how mechanical and simple the cube is compared to other gadgets of that time.

I remember 15 years ago finding many variants of cube with different sizes and number of dimensions (yes, there is a video game of a 4D or 5D rubiks cube).

Hate to say that but it works for me. I am using the largest regular* font size on an iPhone SE and there's no issue on the exact same page in the weather app.

Perhaps OP is using one of the extra-large font sizes hidden behind the "Larger Accessibility Sizes" toggle. It can be expected users at that font size value accessibility over aesthetics. As screen space is limited there is of course a point where things start to look broken.

The weather app could include a TV or clock-like layout for extra-large text sizes but that doesn't really fly with Apple's UI/UX consistency.

It all comes down to cost. These BGA chips have pins under the device unlike older packages like QFP or DIP. The pattern of missing pins is designed so it a fewer signal layers to bring out all the sigal connections in a typical PCB process. Devices with full grids would need more layers or tighter tolerances.

The appeal of STM32MP1 is you can put DDR momery with the chip on a 4 layer board. ST even provides the layout.

I miss this kind of stuff in computer programming languages.

In hardware design, verification is done simultaneously with design, and semiconductor companies would be bankrupt if they did not verify the hell out of their designs before committing millions in manufacturing these chips.

Even among hobbyists this is getting traction with yosys.perhaps its time for programmers to adapt this kind of tooling so there will be less buggy software released...

Next thing they do is to optimize the hell out of kernel process management things until it catches up with the overhead of calling a function in a GC language.

Same thing happened with my work computer in the office network with a MITM HTTPS firewall. The IP address jumps between the coasts randomly confusing the Windows weather widget. Images failing to load on a lot of websites because the IP address change triggers something in their CDN. Everything is working fine when I'm WFHing so it has to be the office network.

Oh and this can also happen when a mobile user is jumping off their home wifi network to a internationally roaming data card. Why they would do that? Because data is cheaper this way, or they are actually tourists. So please do not block users just because they are doing this teleportation dance.

USB4/thunderbolt is a magical protocol. Turns out the fastest way to move data between 2 modern PCs is to connect their thunderbolt ports with a USB-C cable. The connection shows up as a ethernet port on Windows and I can easily saturate a SSD with its 1GB/s+ transfer rate. And it just works (tm). Reminds me of firewire on these 20 yo Macs.

And What happen if you wire both ports together on the same PC?.. Do you get a broadcast (thunder) storm?
