Spacetime isn't quantized as far as we know. We don't know since we don't have quantum gravity or ability to probe Planck scale. Quantum fields are continuous, it is excitations in the field, particles, that are quantized.

I think we need to accept that calendars and clocks are different. Calendars are based on years and days of planets, planets are different, and they don't divide evenly. Clocks are measured in seconds, the SI seconds are basis of units

Pro: Database is perfectly secure. Con: The database no longer exists. Also, there is more to security than memory errors. SQL injection, authentication, and access rules matter. It doesn’t matter if Rust database is secure to bad data if i

Anything that isn't symmetrical. Mice and keyboards. Circular saws. Tape measures. Box cutters. Folding knives. Garden tools. Those are just ones that impacted me recently. Some have lefty versions but there is less selection. I recent

Republic back then meant commonwealth with any form of government. The Dutch Republic was loose union of seven provinces. Republic changed to mean democratic government by representatives without monarch.

There USB over IP. I think Linux supports it. It could be possible to have Pico implementation, use WiFi like this, and connect to computer or another dongle.

The solution is to always add a second name. Like people, projects could have short name and full names. Could be organization (Apache Spark), could use type (Oak Versioncontrol), could be longer name (Violet Spring). Then can use short nam

That's why important to give the scale. dBfs is full scale level, and db SPL is sound pressure level.

It is a weird argument because we totally could build a Great Pyramid replica. Ships and trains hauling stone and tower cranes plopping them into place. We are really good at moving things and lifting them. It would probably be the quarries

If you want cheap missile truck, then Rapid Dragon, dropping missiles from cargo aircraft, is the answer. The B-21 is the B-52 successor, and has to worry less about being shot down.

Northrup has built a couple of prototypes and supposed to deliver first one next year. The B-21 program is going really fast. Air Force are ordering 145, which is slightly more than the B-1, B-2, and B-52s.

The B-21, a cheaper version of the B-2, makes more sense as new bomber since it can do the normal bomber jobs and the B-52 job of nuclear cruise missiles. B-52 engine refurbishment is going to cost $15 billion for 70 odd bombers, or $214 mi

Those are called trigger boards. I haven't found one with buck converter to make 12V. 12V is in earlier PD standard so lots of chargers support it but you have to check each charger and lots don't say. The guaranteed solution is P

I think you are confusing the devices with USB-C that require USB-A, and devices that charge the standard USB-C 5V/3A/15W. The USB-A ones cheaped out in including the resistors that signal legacy USB mode, they work with the ones

The build process is just as vulnerable.

English is a West Germanic language with vocabulary from other languages, primarily French and Latin. But most of the core words are Germanic. It is not a pidgin whose defining feature is simplified grammar.

What are you wanting to use it for? There is using Pi as desktop, which was only option for a while, but now mini PCs are much better. There is using it as server, where mini PCs are better for homelabs and multiple services but Pi is good

This is similar to scam where people are sent messages about bad transaction with a fake link to the bank to verify it. Some attackers have gotten Paypal to send notifications that have the link. People are supposed to check the source and

I have decided that the Pi4 1GB is the ideal for hobbyists. Faster than Pi3, takes normal USB-C charging, and can do most single server or electronics jobs. Which is why it is currently sold out.

That doesn't talk about an increase in radiation. If there was an issue, we would see it in flight crew. There is also a difference with altitude and soil composition, and that would show up in the data.

Planet wide high speed rail doesn't make much sense, it is better of medium sized trips. Flights are will always be better for intercontinental trips. Vacuum trains could be faster but would be so expensive to build. Issues would be bi

150 kW is tiny, that is a single rack. Would have to launch a huge number of them to match the GW data centers being built. There is also a lot of overhead for each one. If Starlink didn't exist, then it could make sense to put edge da

There aren’t even doors between sections. Airlocks are serious things, there is one or two for station for EVA. There are multiple hatches for docking spacecraft. One of the innovations of ISS is larger docking adapter with bulkhead that is

There is the .arpa domain used for reverse lookups. ipv6.arpa is already used for that. But combining the ipv6-literal from Microsoft, gives ipv6-literal.arpa.

I have books that link to online content. I've had one that had printable workbook that that no longer worked because the site had disappeared. Are you going pay the extra money to the developers to keep the servers running? What will

Unlike models with lots of memory, the Pi3 1GB and Pi4 1GB are still cheap, but the Pi4 1GB is sold out everywhere. I think the Pi4 is sweet spot for small projects.

Kessler syndrome is way overstated. One way to tell is talk about it closing off space. That can't happen, it is possible to cross debris bands with low danger. People also don't talk about different orbits. We can use higher low

Nuclear rockets aren't suitable to get orbit, they are too heavy. Also, nuclear rockets can separate the reactor and the propellant, called close cycle. I think the solid core reactors that are feasible send propellant through reactor

I want normal USB-C power. I also want USB-C video output, they might need to replace USB-A port with USB-C. What would be really nice is Zero 3 with 2 USB-C ports and video output. Then have something cheap for projects that was flexible.
