Hello HN, I made this simple notepad for writing down whatever comes to mind. The goal is to force you to not get hung up on what you’ve already written. There’s no formatting, you can’t edit what you’ve typed, you can’t select text or move your caret around. There’s no backspace, delete, undo/redo, or paste. You can’t even see any words except the one you’re currently typing, and when you’re done with it, it fades away. The text is all still there, just invisible. You can save everything you’ve written as a .txt if you want, or just empty your thoughts and let them disappear forever.…

I built a Proth prime tester on a Zybo Z7-20 FPGA ($200 board) and found a new 1,123-digit prime: 2079 * 2^3718 + 1. Proth primes are numbers of the form k * 2^n + 1. They have a neat property: Proth's theorem gives you a deterministic proof of primality, not just a probabilistic test. If you can find an integer a where a^((p-1)/2) = -1 mod p, the number is proven prime. No "probably" about it. The interesting part is the hardware. The core is a 4096-bit Montgomery CIOS multiplier running on a Zynq-7020. It uses 28 DSP48E1 slices and runs at 74 MHz, doing one full modular multiply in…
