Author here - the reason is pretty underwhelming: These are the parts I had on hand when I decided to start on the project. Using a chip with a builtin Ethernet peripheral would definitely make more sense (though I'd be trading any com

If you can only capture 60FPS, you cannot accurate measure a signal of 40Hz, since it is below the Nyquist frequency. (I know you mentioned the slow-mo camera which probably does have the bandwidth).

This is a very first-world opinion. Low-end (second hand) smartphones are some of the only available computing devices available for a large part of the world.

> There's something more constricting about there being one function to bootstrap everything than there is about one file. The trickiest thing is that main() is not even the bootstrap function. The actual entry point of a program

This is the most use that board has and would have gotten in the last 10+ years. I like to think it laying down its FTDI chip for a greater cause was an honour for it.

Indeed - I know I could have also popped out the DIP micro on the board and used it directly, but I choose not to for two reasons: 1. Its so much bulkier, and I wanted something that was the same form factor as my old unit 2. It seemed way

Totally fair point. One of the videos I'm going to get around to making on my channel at some stage is a UART transceiver on an FPGA. Definitely not the "easier in a pinch" I was originally going for, but hey, if you've

You're absolutely right, I don't know why I had attributed the name to the full duplex nature. And of course, there is also USART, where you can have a separate clock line, which allows you to omit the start and stop bits too. A

People can blog about whatever they want. I think people on HN and other platforms often forget: Just because the content ended up here, doesn't mean it was written for here.

I think the authors point is that dd is a specialised command, and for most common tasks (where the precise details don't matter), it's often not the best tool for the job. I didn't come away with the impression that you shou

I can't think of any type of job that is both vilified AND one that you could take on the cusp of destitution. And at least for me personally, setting the example to my kids of integrity being one of the most important characteristics

Heard about a great floating point implementation bug just today. When nintendo released Super Mario 64 for the Wii virtual console, they essentially just made their own emulator that plays a single ROM. The emulator is pretty accurate, tho

If you code to a standard, this is less of a problem. If you implement AES in a way that produces a different output to someone elses implementation, then you by definition haven't implemented AES. From a binary trust perspective, this

I put the warnings in the title and the first few paragraphs, but also implicitly at the end, where the reader checks the comments to see a great deal of reiterations of the message

If someone copy-pastes this code in spite of the warnings, I consider them to be very much in own-risk territory. Sucks if they end up getting burned, but I don't consider myself responsible.
