Unfortunately my workplace is in the countryside. Someone decided it was a good idea to build a big international research center in the middle of nowhere. Which is now a liability for the project, as few people want to come work here.

Quake was notorious for being the first major game to require a powerful FPU. Michael Abrash manually tuned the rasterization code to fit the Pentium pipeline, any other CPU didn't cut it.

This. When my Japanese girlfriend finally visited my small hometown in Spain, she was surprised how lively the city was. Not Madrid or Barcelona, but just a small 100k city. In Japan the big cities are cool, but small cities are ugly and boring.

On the other hand Spanish trains don't need women only cars due to the massive amount of dirty chikan ojaji (old guys that love groping women, even underage schoolgirls). Japan is not a paradise either.

Because these articles always talk about the good parts and never mention the bad parts which make up the vast majority of the country.

I have been living in the inaka for 8 years now and I always laugh at this kind of articles. They only focus on the core areas of Tokyo, Osaka, and a few big others cities, and forget to mention that outside of those areas the whole country is just endless urban sprawl of the ugliest, soulless cities you can imagine.

IANAL, but my understanding is that whatever patents and industrial design rights Nintendo had on the N64 expired long ago, so replicating N64 hardware is perfectly legal as long as you don't use the original logos and trademarks.

Time will tell, but I don't think big enough FPGAs will be affordable any time soon.

And in any case, software emulation is already incredibly advanced, with emulators like Dolphin and PCSX2 arguably being superior to original hardware (4k rendering, anti-aliasing, high resolution textures, etc). Honestly I can't see the benefits of FPGA emulation for 6 gen consoles and onwards.

The MiSTer is already struggling to fit the N64 core, and the GameCube is more than 10 times more complex than the N64. Just the CPU cache and the GPU embedded RAM would be prohibitively expensive to implement on an FPGA, it would require one of the very top of the line FPGAs in the market to even attempt it.

This. My old GameCube is already broken, the optical drive decided to die. Fortunately some Swiss magic still allows it to run games, otherwise it would just be an expensive paperweight.

You didn't understand my point...

Closed platforms like consoles are at the mercy of their manufacturers. If you want consumer rights, stick to open platforms like the PC.

> It cannot be a "pretend" manifestation, when a physical disc that requires nothing more than an official piece of hardware to use continues to work 100 years into the future (assuming the physical hardware survives that long.) Those are the "rights" that are being fought for in this instance.

That's a pretty big assumption. Back in the day I bought a GameCube and decent game collection. I tried it a few months ago and the optical drive is dead, so now my games are just expensive coasters. I could buy another one in the second hand market, but given their age it will also die sooner or later.

That is the problem with proprietary console media, once the hardware inevitably dies, the media itself is useless.

Graphical adventure games were already dead before the Xbox even arrived, and besides that the first Xbox was not that popular outside North America so it could not have affected other regions.

You don't double integrate, period. You essentially have three options:

1) An absolute positioning system like GPS.

2) A visual positioning system like fiducial markers or SLAM.

3) Something that can measure linear speed and then you integrate the speed only once. Easy to do on vehicles, but even the most accurate system will quickly drift.

12 years ago I had to write the firmware for an IMU. It took me some real effort to convince my bosses that double integration was, for all practical purposes, impossible. I wish I had known about this video back then...

IMU are very useful to known your orientation though. Even an inaccurate IMU is useful to provide an initial estimate to feed vision-based algorithms.

For those who are not aware, Soviet scientists actually developed ternary computers back in the '50s: https://en.wikipedia.org/wiki/Setun

Ternary encodings are also popular for data transmission, for example both USB4 and GDDR7 use PAM-3 encoding.

Yes they are. Every time I visit Tokyo I try to avoid Shinjuku because it is extremely confusing and I always get lost.

Signs are mostly useful for people who are new to a place, if you need a significant amount of time to familiarize yourself then they are useless.

How do you expect tourists, including people coming from other regions of Japan, to familiarize themselves with the layout?
