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 mechanisms to prevent that.

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 struggle with multi-thousand page documents and non-native sea

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 thing, just look at the linux-flavoured C.

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 stopping times are highly unpredictable, a lower number of

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, a combination of batteries for smaller, reg

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 Cortex-M yet, especially in regards to the Sec

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 associated downtime while restoring to a different server

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 parameters, creating CRC structures, diffent logic for different wor

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 track of clock domains seperately from normal signals. My iss

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 for europeans, as cheap gas and oil from Russia w

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 search keywords.

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 code. In my opinion, it's even more of

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 practice before.

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 local machine is usually also highly constrained in computing p

Most car trips could be replaced with ebike trips, but the majority of distance travelled (and thus, roughly, carbon emitted) can't. 80% of the distance driven is with trips >10 km, 70% of the distance driven already at >20 km. T

RISC-V is even worse: The Cortex-M series have standardized interrupt handling and are built so you can avoid writing any assembly for the startup code. Meanwhile the RISC-V spec only defines very basic interrupt functionality, with most MC
