"What Tesla is doing is inferring it from two cameras." People keep repeating this. I seriously don't know why. Stereo vision gives pretty crappy depth, ask anyone who has been playing around with disparity mapping. Modern ma

Just tried from Terasic website. Tried to order two for $225 each, they seemed to be available. That said, the price has almost doubled in a few years...

My MiSTer FPGA was about $200 before I was playing games. $700 is either hyperbole or have DE10 Nano board prices really gone up THAT much? After DE10 Nano, you need just a RAM module and a I/O board and you're ready to go.

An FPGA can be 100% hardware perfect with practically no extra processing cost. The potential is there, even if it's not initially exploited. CPU based emulation will require a fairly powerful CPU just to emulate SNES. It's pretty

High bandwidth phased array LEO satellite internet is a relatively new concept. Give them some time.

I think they were geofenced all along. Otherwise Russians could have used captured Starlink terminals to their advantage. Nothing to do with Starlink or Musk. Those orders were from the State Department.

Assuming everything is reported fairly, I really can't imagine being Nichia's customer. Ever. Sacking and not compensating the employee that single-handedly made Nichia successful by inventing a working blue LED and saving Nichia

Spoofing a Starlink receiver's GPS is not going to be very helpful with phase-shifted array antennas. Both the satellite and the terminal need to know each other's position. https://en.wikipedia.org/wiki/Phase

Why would you need a coprocessor or hardware multiply? It's all tiles and sprites just like Super Mario Brothers. Ok, on the Spectrum software emulated, but still. Tower rotation is achieved by scrolling (well, rolling really) 8x8 char

Wasn't that about one incident, where the driver was in a traffic accident before the wheel fell off? Wheels are actually designed to fall off in an accident.

It's another tool in the toolbox. Can't have too many of these! In the end, you'll need to profile it on your target chips.

MAME's cheatinit is just like ye olden C64/Amiga Action Replay and Final Cartridge days. Scan the RAM, die once in the game, scan again for decreased values, repeat until just one address left. Then patch that address for unlimite

I'm assuming it's done with video tricks, like compositing etc. I'd certainly hope no one was actually endangering anything!

That'd be pointless. There are way better solutions for ICBMs.

If near a ground station, can't the satellites just use their standard radio links to cover that? Might be an issue for Antarctica and major seas.

I guess the problem is that most of the useful bits of that 10 TB are going to be most of the time somewhere far away from the target audience. You have to share that 10 TB with everything on that satellite's orbit.

No one, unless you’re using a CPU emulator or a JIT with an SPI RAM. RP2040 doesn't have memory protection / virtual memory capability and has only 264 kB (or so) RAM.

Would it really even matter? Is there anything you'd do differently if we're conclusively determined to live in a simulation?

Please note I was talking about Windows 10/11 command prompt. Your tip works on Linux.

Right, vaguely aware of that, but been a while. Thanks for correcting!

Thanks. Pretty nice!

Just discovered today standard ANSI escape sequences work on Windows 10 command prompt. Even 24-bit color works fine! Try (not possible to copy paste, see [1]): echo ^[[48;2;255;0;0mHello^[[0m Hello is printed with a red (RGB(255,0,0

Nothing prevents you from using a smaller MTU... well "TU" for TCP frames. Less packets to process would speed things up. Fever headers to process. Also if your TCP flow bandwidth is counted in tens or hundreds of gigabits per sec

by vardump 3y ago
It'd be great to have an MTU of say 64 KiB or greater. Although I guess you'd also need a longer than 32-bit CRC to detect all the possible 3 bit errors past 11 kB frame size. A 40-bit CRC would be sufficient, at least up to 188 k

Hmm. Should we also get lasers attached to our eyes and chant "resistance is futile"?
