No one went to jail when my grandparents died. Stop spreading lies.

Thanks, I have an EE education, but I didn't really understood what charges were doing in a BJT. I can use them and apply the formulas, but I never really "grokked" them. This makes it clearer.

Counterpoint: I know my car can brake and turn much harder than I do (it's not a sports car by any mean, but that's beyond the point). I'd rather not change my tires and brake pads all the time though, and keep some margin fo

Once any HDL is translated to a bunch of primitives (gates, LUTs, flip-flops, etc), that's the job of an automated place-and-route, which already exist. It's independent of the starting language.

The graphs are beautiful, however they're independent of the language (because they're a visualization of the resulting gates). You could get the same graphs from VHDL or Verilog. I don't like the "fallback" mechani

Good for american hobbyist I guess. It's not an option where I live unfortunately (orders above 75€ have free shipping though).

Some still do, but they'll only send to businesses, not to individuals. What's annoying for me is Digikey and friends insisting on only delivering with express carrier. I'd like to have a cheaper, slower option.

Assuming the orbit is at 200km, these mirrors could only focus the image of the Sun on a 1.7km wide disk (that's (Sun diameter)/(Sun's distance)×(Earth distance)). Moreover, the Sun's illuminance is about 1kW/m2 aro

It's not for doing nothing, it's for fooling around at the edge of knowledge. Sometimes, very useful stuff emerges.

Conveniently, there's already an electric cable sized to transport a few MW nearby. This might reduce the cost of installation, also there'll be no land acquisition/impact study issues. However, I agree that putting solar pan

That "if it hits a populated area" reduces the probability by a factor 100 (because about 1% of the world's surface is urbanized [1]). So the actual frequency of "city wiped" is more like once every 10000 years. Com

The french government (more pro-business than pro-ecology, but not climate deniers) is seriously planning for how to manage 55C heatwaves around the half of the century. Because climate scientists agree that's what's coming (excep

European here. Maybe I'm not typical, but I know that the contiguous US is about as large as the EU (around 4000 km from one side to the other). And if you need 24h to get to the other side if a state, you're either on dirt tracks

I don't understand this argument. When someone uses a tool to create something, they are the copyright holder. Why would it be different when the tool is an LLM?

Really nice article, I'll look closer to green lights next time I see one. The most striking experience I had was working with a blue laser (430nm). The best way I found to describe its color is that it was screaming "blue" a

You got it backwards, Watts are Joules/second (or joules are Watt•second).

Enjoy the annoying-to-debug errors when someone inevitably mixes arr[0] with arr[1] and tramples the heap (this could be mitigated by accessing the fields with macros), or writes arr[3] because they forgot this is not a regular array.

The second tome I had to do that for the same project (new computer), I sarted taking very detailed notes when doing this kind of unpleasant, supposedly one-off things.

Inference can only happen after having invested in training and datacenter construction. Arguing about "inference profitability" sounds a lot to me like ignoring large cost centers of these comanies.

To be clear, I was answering your second paragraph, about "funding oil extraction that is happening anyway". I understood this as "buying shares directly from the extracting company". I agree that buying on the secondary

Both are asking for money to extract oil (and hopefully sell it for more money). I don't see why the oil well being already drilled or not should make a difference if I don't want to invest in CO2-producing endeavours.

The space shuttle stack has a net thrust (thrust minus weight) of about 9 MN at lauch [1]. High carbon steel has a yield strength of 700 MPa [2]. So you need a piece of steel with a cross section of 0.013 square meter to hold it down. That&

For electronics without wireless functionality, it is allowed to self-certify. Anyone could also print whatever label they want on their products illegally (i.e. without doing the required paperwork to self-certify). The policemen controlli

There's no free alternatives, because AMD doesn't document the bitstream format (i.e. what you need to push to the FPGA to program it to do wha you want).

People change their minds. Is that illegal? Maybe they had the intention to only be in the US temporarily at first, but now they'd like to get permanent residence. Why shouldn't they be able to apply for it, from the US, while sti

That's what formal verification is about. I did some (using PSL for hardware verification); writing the formal spec is way harder than the actual code. It will find a lot of subtle issues, and you spend a most of the time deciding if i

Thanks, I didn't think synchronizing the pixel clock would be needed, but this makes sense.
