Bell Telephone Company was first to the market and won. It's now known as AT&T.

Sounds interesting, thanks for sharing. How is the quality compared to RealSense? Do I understand correctly that OAK-D camera requires two cables (USB-C and barrel jack power), not just one?

Zed cameras has a very hostile EULA (borderline illegal, but IANAL), I would not recommend using them unless it's absolutely the only option.

Yep, the AKS primality test (2002) was such a surprise to many (including myself) at the time. Most importantly, it did not rely on Riemann hypothesis, which remains unresolved. 1. https://en.wikipedia.org/wiki/AKS_prim

Just an observation: by this metric, bison meat is approximately 200 times more ethical than chicken meat.

to a certain degree, SpaceX is so successful, because they allow themselves to have that attitude.

The diameter of this asteroid is estimated to be ~160 km, which is 21.7 times less than Moon with d=3474 km. Assuming similar density, the mass of the new asteroid is 10000 less than Moon and it's unlikely to affect much.

They didn't ship with mine! :) Probably, an update to a later version. I don't know?

Sadly, by the time I discovered the community improvements / hacks, my kids lost all the interest. Hopefully, Spintronics would be more reliable, given that the author is well aware of the unreliability issue with Turing Tumble.
524.
by krasin 5y ago
Yes. But kids like to be exposed to the joy of engineering first. It's otherwise hard for them to justify the pain that's required to get to the joy of success.
525.
by krasin 5y ago
Yes, this is from the same person. Turing Tumble is almost amazing. Unfortunately, gears and balls used there are not reliable enough and more complex circuits have abysmal reproducibility (~50%). I tried it with my kids and they were very

Interesting. Thanks. Then my explanation of the observed phenomena is likely wrong either partially or fully.

Obligatory reference to "Made in Japan" by the founder of Sony: https://www.amazon.com/Made-Japan-Akio-Morita-Sony/dp/045115... TL,DR: Japanese went through this cycle as well. And I would say Chinese to

To be more precise, without using German scientists to the full capacity. This multi-channel telemetry was enabler; Soviets followed the same approach as SpaceX is doing: lot of launches, lots of explosions and learning something every time

One of the best books about soviet rocketry is "Rockets and People" ([1]). My blood boiled at how badly German engineers were treated on the Soviet side and how inefficient the use of their skills was. They literally landed German

Thanks for the kind words! Yes, I am in SFBA; I know about Saildrone; Sailbuoy, Liquid Robotics and a few other similar companies pursuing small data-collection drone boats. I didn't hear about Sofar yet - thanks for the link. As a ful

I hope we get rid of cargo ships that burn matter. But sails are too high maintenance to be scalable. Last year, as an experiment I've launched a tiny solar-powered boat ([1]). Ultimately, it was too small and underpowered only making

Got it. I can relate: while Python 3 support is probably fixed now, I agree that Bazel tooling for adding toolchains has been always abysmal. Things somewhat get better ( https://docs.bazel.build/versions/master/too

An interesting case that's hard to support with Bazel. Note: I don't quite like Bazel; but my take is that Bazel supports too much configurations and options: my workflows are always much simpler. Which is why I am curious to hear

by krasin 5y ago
Can you please give an example of such an interesting case? I am genuinely curious. And I agree with the general point that monorepos require a great build tooling as a match.

by krasin 5y ago
I really like monorepos. But I find that it's almost never a good idea to hide parts of a source code from developers. And if there's some secret sauce that's so sensitive that only single-digit number of developers in the wh

Yes. Error checking but not error correction. Bit flips are detected, but they are usually handled with a panic on one of the sides. In Ethernet, on the other hand, packet loss is routinely handled, and higher level protocols can work when

by krasin 5y ago
These cables would work for power and maybe even Ethernet. The problem with USB is that the protocol is designed with no data loss in mind. A single bit flip due to EM interference or bad cable, and the camera firmware (or the host driver)

It's safe to say that orchards are not changing anytime soon. These robots are not useful yet, and to demonstrate their utility they need to work on existing orchards. Only once everyone is using robots for apple picking, we might see
