Is buying hopefully broken electronic test equipment at the flea market, fixing it and then blogging about it a niche hobby?

As an experiment, I just now took a random section of a few hundreds bytes (as a hexdump) from the /bin/ls executable and pasted them into ChatGPT. I don't know if it's correct, but it speculated that it's part of a

I've cut-and-pasted some assembly code into the free version of ChatGPT to reverse engineer some old binaries and its ability to find meaning was just scary.

Their stash will explode. LLMs can do this on binaries just the same, and there's a lot more closed than open source SW out there.

Have you heard about clock buffers and hold violations?

AFAIK, creating latches is just as easy in Verilog as in VHDL. They use the same model to determine when to create one. But with a solid design flow (which should include linting tools like Spyglass for both VHDL and Verilog), it’s not a ma

My memory is definitely rusty on this, but you can easily construct cases where the VHDL delta cycle model creates problems where it doesn’t for Verilog. I remember inserting clock signal assignments in VHDL to get a balanced delta cycle cl

I used to be a huge VHDL proponent, talk about the delta cycle stuff, give VHDL classes at work to new college grads and such. And then I moved to the West Coast and was forced to start using Verilog. And in the 21 years since, I’ve never o

One of the choke points of all modern video codecs that focus on potential high compression ratios is the arithmetic entropy coding. CABAC for h264 and h265, 16-symbol arithmetic coding for AV1. There is no way to parallelize that AFAIK: th

The relevance is that you don’t need to assume that the knife wielding person can hit you from a distance. One way or the other, this doesn’t seem to be a problem in other countries.

by tverbeure 7mo ago
4% is the standard number that's quoted by pretty much any financial planner. It's based on backtesting and assume that there's be large downswings along the way.

by tverbeure 7mo ago
FWIW, the 4% rule is for safe withdrawals for around 30 years of retirement, as in, you retire at 65 and you hope to live until 95, and even then it has a non-zero chance of running out of money. It's not a percentage you should use if

I don't know, but model names such as "kimi-k2-thinking" in the test set might offset a clue.
