You sound paranoid and schizophrenic you should honestly try explaining your situation to someone you know or a professional. I think you’ll realize that your thinking is a bit delusional. I can’t really understand what you’re saying here.
The profile you responded to "techbro" was made 3 years ago, has 102 karma (i.e. 1 upvote every 10 days, on average), and has never submitted anything - zero submitted articles or profiles. My profile was made 12 years ago and has 3,118 karma (approximately averaging an upvote every 1.4 days) including lots of submissions of stuff I made, for example this Show HN that I was pleased to see make it to the front page with 36 points and lots of positive comments: https://news.ycombinator.com/item?id=43141139 (the resource itself is currently offline as I've temporarily replaced my website with 50 reasons why it's wrong to disrupt communications between a husband and wife. I'll replace my website as soon as this issue is solved.)
Right up your alley, I've actually written a cryptographic case study of some of the dynamics of this, I've just sent you a copy of it (you and I were in touch before - it was very well reviewed by professional cryptographers.) In your reply to this, please acknowledge your receipt of my email, and if you can, print it out as well, as it can become inaccessible later.
Of course, there are a lot of NSA-affiliated people who could come out of the woodworks to support parent's slander that I "sound paranoid and schizophrenic".
The reason they don't? They're witnesses in the FBI case and don't want to go to prison themselves. The FBI has already handwritten over 10,000 affidavits in this case. (They are writing by hand to avoid electronic tampering with evidence.)
I am not making a media story about it yet, which would be the next step, so there are no articles about this yet.
My reason for not doing so is not to bring extra attention to the case, but simply to solve it in a straightforward and expedient manner.
Cuda optimization actually doesn’t suck that much. I think NSight studio is amazing and super helpful for profiling and identifying bottlenecks in kernels
The problem is that their efficiency at converting electricity into projectile kinetic energy is really bad (like single digit percentages bad), getting electrical energy and power density is quite difficult in the first place (capacitors have abysmally bad energy density compared to gunpowder), and coils absolutely hate having their current changed quickly (which you need for this to work).
The problem with coil guns in particular is the ferrous slug is drawn to the center of the magnetic field. The field has to be collapsed at the right time to avoid sapping velocity from the slug, counterproductively.
Many designs that achieve respectable velocities use a multi-stage coil, which requires precise timing for each magnetic field, a lot of power, and high current capability. Generally, that means large batteries for a power source and large capacitors to feed the coils, which becomes heavy and expensive.
Even rifle variants rarely make more energy than a .22 LR, a feat which is easily overshadowed by air guns several hundred years old.
The electromagnet isn't the issue, it's the capacitors to power the magnets. A coil gun capable of matching a small handgun would be too heavy to reasonably carry. At the scale where they could become competitive with a conventional gun, you have an artillery piece.
