I would attempt to restructure your code so it doesn't have to re-process all the records every day. For example, an average function seems to need all the data, but if you store the sum of all previous values and the number of records then you only have to add the new values and divide by the new total number of records.

If you have a machine that has a 1000 parts plus tens of thousands of lines of code, and the machine injuries somebody due to an error in either the code or one of the individual parts does your magic intervene here? Maybe the person who wrote the code or made a specific part just wanted to leave work on time and made a mistake. Does that mean since there is no ill will the accident still happens, or does you magic somehow know the part will fail and makes them correct the issue?

Technically the amount of energy available is E=mc2 where M would be the mass of the earth, however at our current level of technology we can't exploit that with efficiency so the practical conversion would be significantly less.

Instead of landing directly on the cliff, what prevents them from landing nearby and using an elevator to bring the cargo up? Is there a lake they can do water landings with pontoons.

@FrogOfJuly In what size diameter are you deploying your spotting system? Is this just around the earth about 8000 miles? Does your spotting system include the entire distance from earth out past the moon? Is it bigger than that?
cybernard
Jul 30, 2023 18:04
@FrogOfJuly What diameter around earth are you trying to do this in? The moon is 230,000 +/- away from earth? I ask because if you want an effective defense your going to need minutes if not hours to "man the battle stations", so technically you need as wide as possible. Even just going around the moon doesn't provide use with much time to react unless their going at some ridiculously slow speed for some reason. Logically, would warp in, at some percentage of light speed, sends out its fighters in a surprise attack before we could muster an adequate defense.

@FrogOfJuly I googled it. nationalww2museum.org/war/articles/… What kind of distances are we covering because even 1000 miles is insignificant in outer space.
cybernard
Jul 30, 2023 18:04
The issue I see is the TSAR bomb covers 150miles. Light travels at 186,000 miles per second. You can sweep a 1000 mile grid in much shorter time larger effective radius. The cost of enough nukes is going to be crazy along with the raw materials required to produce them. Laser could be powered with solar panel or nuclear for a long time with less resources. Therefore, a grid of lasers will cover more space, cost less, and not fill outer space with radiation. Even bombs from earth to Mar's shortest orbit would use ALL the nuclear material on earth.

For many thousands of years people either didn't know or believed the earth was flat, and surely over that large of time scale someone draws the symbol accidentally and boom we have a major problem. Until Galieo people believed the sun and planets revolved around the earth, so reality would change and that would cause major issues.
cybernard
Jul 3, 2023 18:05
I think the real problem is universal constants like PI and gravity. People commonly believe PI is 3.14, but it isn't that is rounded. Same thing happens for other important constants like gravity, a slight rounding could cause the planets to fly off or collide into the sun or jupiter. There's exist about 12 constants and if each one was rounded our world/universe would be bad.

his weakest energy output in that level will render our galaxy into deSitter Space/the big rip Doesn't that mean he can't use ANY powers? The use of his power would surely crush the earth killing everyone including his relatives. Even 1,000,000th of that would eliminate the earth. Seems like we need to get rid of him, as a sneeze could wipe out a city.

The question is does this ship have a crew as in a generational ship? As long as you have the ability to do maintenance the ship will continue. What kind of manufacturing abilities are on board? As long as you can manufacture replacement parts for 100% of the ship it could be self-repairing.

@TrickyZerg Regarding you could use dd but used improperly it could erase your drive or part of it. I usually use bonnie++ in linux. Sysbench could also be used. Just remember that because of the nature of file systems your actually speed will be a bit slower than the RAW performance of the drive.

It doesn't really matter because 3.0 is 600mb/s which not achievable by ANY hard drive. Even 2.0 or 3gbps is 300mb/s which is not achievable by any hard drive. Now if you had SSD you could expect to achieve 500-600mb/s. I looked up the hard drive and even its best non-sustainable speed is 195mb but is typical 147mb/s. Just barely over SATA 1 speeds.

Why do they not have solar panels, wind turbines, generators to provide them with electricity and entertainment. Modern TV can be 50w and with a few batteries a TV can run ages on a single charge. If there near a stream maybe they can even have hydro power. Keeping these things maintained will surely keep a percent of your population occupied.

You need to take time to break each part of the project down into manageable pieces. If its going to take more than 1 week it should be its own piece. Then you can identify what you need to learn to make progress on each piece. Then spend some of your time making progress, and some of your time learning. Identifying pieces that you are lacking skill can help you boss hire you appropriate help.

I did some math 60*60*24 = 86,400 * 3.3814oz =432 gallons of boiling water per day. This is not a very effective weapon. The fact is you can only get 18 gallons per hour. I think the usefulness of your weapon is looking pretty bad. user535733 suggestion to start a tea shop is looking pretty good right now. Also water doesn't stay hot for very long within 30 minutes boiling water wouldn't be boiling.

Castle dumped scaled oil,tar, or etc on people from castle walls there's no reason why it can't be water. Although its not as sticky as tar or oil so it might run off faster.

Problem here is that you don't let people in at 100 so there can never be greater than 100. Even then it is doubtful people will battle-royale as only a couple people need to die. Given a choice people would eventually leave for a different area. Eventually people would figure it out, and pass laws to prevent this from ever resulting in battle-royale. They would be 90 person limit (for safety margin), and if you have a child you have leave town. No battle-royale.

@user2352714 I am saying most of the people you listed could be residents of said town. Nobody who works in your town is gonna to live more than 2 hours away because even then their commute is 4 hours a day. There is no reason why said town wouldn't have all the standard laws.

In addition to this great answer I would like to add a "home owners" associate could be a great addition to the gated community. Keep the most normal people along the perimeter, and the other more abnormal in the middle. Also placing it at the top of mountain would keep people from looking in from any direction.
cybernard
Feb 6, 2021 00:04
@RBarryYoung If the gated community is large enough it will have its own police force, post office, and etc all staffed by non-humans. From the outside nothing will be appear to be wrong. Every police officer will behave mostly like any other police office, and file tickets and reports. Some stuff you can even cover up by saying the residents were wearing costumes.

What kind of explosives do they have? C4 /dynamite or nitroglycerin? Because nitroglycerin predated both but it was super dangerous to work with and you will lose hundreds of lives a year due to accidents. Based on en.wikipedia.org/wiki/Timeline_of_steam_power and this "The first steel-frame skyscraper was the Home Insurance Building (originally 10 storeys with a height of 42 m or 138 ft) in Chicago, Illinois in 1885." approx what year are we talking about? Also how many floors does your average sky scraper have?

Some libraries may have special collection that you may not check out at all and/or not well advertised. Textbook too delicate or rare to checkout. Our local universities has some of the hand written pages by JRR Tolken (lord of rings) and its only real advertised to students. If I hadn't known someone working there I would have never known, so therefore to me it was a secret. Anyone can schedule an appointment but it is so poorly advertised and little known that it might as well be a secret
cybernard
Sep 1, 2019 16:28
Libraries may have reserved copies of certain textbooks only for students of a certain class so they don't run out, but thats only secret as in publicly we have 2 copies for check out but 20 for specific students to check out.

This is an over simplification, but if you put a red transparent sheet in front of a flash light all light from it appears to be red. Well if the insects can't see red, we don't exist. So shift the light into spectrum of light the bugs can't see, even if its infra-red,x-ray,gamma ray, or etc.
cybernard
Jul 22, 2019 19:29
I wonder what part of the visible light spectrum the bugs can see because light naturally red-shifts due to acceleration?
cybernard
Jul 22, 2019 18:52
@TracyCramer Sorry I mean Mars not Mercury. Our sun has a habitable zone which the planet Mars is the last planet to receive enough heat to be habitable. If the bug creatures are at Pluto no useful amounts of heat will reach them from our sun.
cybernard
Jul 22, 2019 18:52
Also each star has a habitable zone. In our solar system only reaches Mars at best so is heat really an issue? All the other planets in our solar system are cold dead rocks, except those with internal heat of their own. Also what are we doing about the light generated by the rest of the objects in our solar system. In order to get any heat from our sun they have to reach 150 million miles of our sun, are they really going to get that close? The other planets in our solar system generate even less or no heat so they have to be super close to detect heat
cybernard
Jul 22, 2019 18:52
Note: You can have underground greenhouses using LED lighting so can have all the plant life you choose to preserve. Question: Speed of Light issue, if we shut everything down today it maybe years before it disappears for them. How far away are they? (in light years). If everything goes perfectly how long will it take them to pass through our neighborhood and be safe again? Also the heat from our sun only reaches Mercury at best so is this really an issue? The solar winds go much further do we need to hide them because you say only heat and light so I am inferring a no answer.

Approx how many square miles of ice do you need cleared? Having primarily surface mount building that shift with ice would be more practical at least.
cybernard
Mar 11, 2019 18:34
So let me get this straight.... You want to remove a nearly unbombable sheet of ice that would provide a free naturally occurring layer of armor for any underground bunkers?? Are you crazy? I say we keep the ice, and only dig small holes for our buildings. Maybe a couple farms, and that is it. Air craft can land virtually anywhere on a smooth sheet of ice so its great for air bases.
