> Nuclear has the most bizzare cost curve of any new technology where every year it costs more than the year before; a pattern which makes effectively no sense and is really only e…

The PS5 and Xbox are also very close to being an x86 PC, but you're not installing your own OS on there even though there are few technical hurdles if the manufacturer removed the …

A PDF of a long document such as a standard or reference manual is almost always preferable to an HTML version. HTML versions have issues with formatting, searching (as browsers st…

It's often a requirement for bare metal embedded development (too heavy in terms of memory), so it's basically unavoidable. Non-standard languages are very common for this kind of …

Signal Priority only works well if the arrival time of the bus can be predicted some time before arrival at the signal (~30 seconds is a number I've heard a few times). As bus stop…

Certainly not with hydrogen directly. It might be involved in the production chain, but it's such a pain. If it's at all possible to electrify, that'll very likely win. For flights…

It's still the lingua-franca of ASIC/FPGA/Simulation, especially for scripting the tools. I think it's slowly being replaced there by Python, but it's very slow.

The Hazard 3 is basically a hobby project of Luke Wren, a Raspberry Pi Employee. He's contiuing to evolve it further, but I don't think it's ready for a full replacement of the Cor…

My "Homeserver" with its database running on an old laptop has less downtime than AWS. I expect most, if not 99%, of all businesses can cope with a hardware failure and the associa…

One of the reasons amaranth (and other neo-HDLs) is so great is the full-fleged seamless integration with the host language. Generating DSP filters using the numpy for all paramete…

What are the benefits of SV for multi-clock design? I found migen (and amaranth) to be much nicer for multi-clock designs, providing a stdlib for CDCs and async FIFOs and keeping t…

> There's still relevance in making it stupidly easy to make an LED blink and make basic apps on circuit boards. Education + weekend hardware hackers might look for something diffe…

How would you effectively stop windows updates to china? Bypassing the Windows activation measures isn't stopping single pirates (or people still wanting Windows 7 updates intended…

While energy is expensive, I find it hard to blame on the "green stuff". The majority of the energy cost increases in the last few years are because fossil fuels got more expensive…

It takes a bit of effort to add all you would want and, for me personally, bangs can be anywhere instead of having to be at the start of a search query as is needed for custom sear…

And to avoid having two sources (perhaps with slightly different voltages) connected together and leading to hijinks. E.g. a usb A-C cable plugged into a USB-C power supply.

That is the point of Amaranth (and migen). It's not HLS, it doesn't try to generate logic from normal python code. It's an HDL implemented in python, not trying to look like python…

Alon Levy has also written some more on Tram-Trains: https://pedestrianobservations.com/2020/11/03/tram-trains/ A few points I want to add: The Stadtbahn (called Tram-Metro in this…

Mont (if not allmost all) S-Bahn trains in Germany only have one staff member. The space for wheelchairs is directly behind the drivers cabin and the few times I've seen a ramp bei…

Current modern nuclear reactors getting built are huge. Maybe, perhaps, in the next decade or two we'll see small(er) reactors, but this isn't a new idea and hasn't worked out it p…

It seems like this is already deployed in Arch, as I've hit it yesterday. I was surprised at first, but it was quite useful.

As the local machine is there anyway, only the increase in energy usage should be considered, while the server only exists for this use case (distributed across all users). The loc…
