At least with a small contributor's team, the problem with AI PRs is that the (most of) feedback is useless. In hand-written PR, I can write a comment about better way to do something, and my teammate will learn and use better methods

DTL, diode-transisor logic, was used in 1960-1970's when they did not have cheap high-quality transistors yet. The power consumption was pretty terrible, but you needed less semiconductors. In the modern logic, diodes are not that usef

And the first thing you do to them is to convert them to binary. Look at any Ethernet PHY for example - you have that nice 5-level signal coming on.. and the first thing you do is feed it into AFE/ADC so you get digital signals that yo

there is nothing special about negative voltages, it's all relative to some point anyway. With mixed analog/digital circuits for example, it's pretty common to treat exactly same voltages either as -2.5/0/2.5 (relat

This is a board with RP2040, and FPGA. Github page[0] has more details. They only refer to FPGA as "1120 LUT FPGA". It is Renesas SLG47910 "ForgeFPGA". It comes from free (free-as-a-beer) toolchain from Renesas. The boar

My belief is that people care more about things that affect them directly. And this means your pro-control statements like "I pay a known enemy of state to fund a terrorist attack" are pretty abstract - do you know anyone who fund

Yes, running server farms in production is complex, and docker won't magically solve _every one_ of your problems. But it's not like using deb files will solve them either - you need most of the same components either way. > If
