Your numbers appear to be way off. Commercial reactor grade Uranium is enriched to less than 20% (typically about 5%) while weapons grade Uranium is closer to 90% (the first U-235 bomb was enriched to 80%). Some specialized reactors do us

I'm curious how you were able to source the parts to replace the burned out transistors and other components.

That's from a study that was done after the accident. As far as I'm aware NASA never even considered a rescue mission while Columbia was in orbit. They simply assumed that if the tiles were damaged there was nothing that could b

It all depends on what kind of programming you do and what kind of math you're talking about. Some types of programming are highly dependent on math, such as 3D graphics programming, data science and machine learning. Others have les

It is however safe to say that there are a lot more eyes on those 400 npm packages than there are on the Windows source code. Moreover with the spread of bug bounty programs I would expect that the likelihood of security bugs in widely use

There's far more to hardware than just designing the logic circuits (open source designs do exist such as Risc V) you also have to fabricate them and the processes for fabricating CPU's, GPU's and similar chips are probably t

80% of what you need to know to be a good programmer is best learned through programming, not course work, and the other 20% you can learn on your own from books. I only ever took one formal CS course but that didn't stop me from buil

What exactly do you mean by that ? Are you talking about an IBM emulation product that runs on RH Linux ?

Your examples don't support your argument very much. Export controls on cryptography were eliminated decades ago as it became clear that they made no sense and were counterproductive in a world where the Internet exists. Patents are a

Aside from the details of this specific proposal it seems to me that government mandates on what end-user software can do is uncharted territory. How would this affect open source browsers ? The most widely known browsers (ie. Chrome and

My guess is that only a small fraction of HN users are going to be able to figure out what this is for without spending a significant amount of time doing a deep dive into 5G (I don't belong to that fraction, btw).

I've had a small amount of experience with this sort of thing, though not with the full blown streaming apps like OBS. For example I've written an Android App that sends video frames from a phone's camera to a remote client.

Well, I know that I could live spending less than 50% of my monthly income on food. Ignoring other subsidies however my rent would cost over 80% of my monthly income, so if I paid my rent, as people are likely to do first, it's true t

Can someone explain why neon is critical for "lasers used in chip manufacturing" ? I don't think they'd be using He-Ne lasers, and if they are I would think those could be replaced fairly easily with solid-state lasers.

Thanks, that's useful information that I haven't seen anywhere else.

Yes, I was confused because my Dell laptop power input doesn't have 3 wires (unless there's somehow a third wire buried in the barrel connector), so I was assuming that the ID signal is somehow just combined with the actual input

by tgflynn 5y ago
I guess it would also be helpful to know what range of laptops this is for. I was assuming it was for relatively recent models. I have an Inspiron that's about 5 years old and it has a barrel connector for power. It's not obvio

If the connector on the left represents the output of a generic power supply then I still don't see how you would connect this on the laptop side. EDIT: On further thought I think that connector must be intended to represent the laptop

I assume the purpose of this would be to build a Dell compatible charger but this repo doesn't appear to provide much information on how to actually do that. I get that the microcontroller provides the signalling the laptop needs to i

Cameras are cheap and readily available, can detect most objects that humans are interested in and don't depend on having access to modify the objects you want to track.

by tgflynn 5y ago
If you have 2 cameras observing the same object and you know their coordinates and orientations in 3D space there's a fairly simple algorithm to recover 3D coordinates from pairs of matching pixels between the two images. It should be
