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.

One solution is local seconds and SI seconds. Another is use metric seconds for stopwatches and local minutes for scheduling, and accept there is uneven number of seconds in minute.

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 it lets anyone in to do anything. Or if it is crashing all the time or corrupting your data.

Same here. I realized that will never be good at precise games.

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 recently found a left-handed weeding sickle and it is the best thing. Most of them are just annoying. I can do most things with right hand but then have to switch hands instead of the natural motion. But there are a few that are dangerous.

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 name internally, and full name globally. I like the type name cause tells what it is.

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 that be the bottleneck.

If wanted it in concrete, would be faster. Or could do it in steel or steel/concrete with some interior space (Luxor in Las Vegas is size of smaller pyramid).

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 million each. $750 million is current cost of B-21.

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 PPS chargers that have variable voltage.

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 in the cable or adapter.

Lots of people assume that USB-C always uses USB-PD, but the basic signalling is done with resistors. Lots of devices only need 15W, and it is better than USB-A charging. If you want faster charging, buy more powerful chargers.

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 for lightweight single service. Then there is hobbyist use, where Pi is cheap when get lightweight one and has ecosystem of hardware and software.

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 go directly to bank, and this will bypass that.

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.
