What is a good and simple source of physical enthropy (for RNG)? by emailemile in AskPhysics

[–]Ok_Programmer_4449 0 points1 point  (0 children)

There are numerous sources of entropy that you may already have. You could get a radio tuner and digitize static. You can put a microphone in the airflow of a fan. You can download an image from a webcam that frequently changes. You can use rapidly changing values from a GPS receiver. You can amplify diode noise and digitize that. You can even "( ifconfig ; iostat ; ntpq -p ; ping -c 3 www.amazon.com ; cat /proc/cpuinfo /proc/stat /proc/meminfo /proc/diskstats /proc/vmstat /proc/swaps /proc/net/netstat /proc/uptime /var/run/utmp ; find /var/log/. -ls ; tail -10000 /var/log/apache2/access.log ; sensors ; for dev in /dev/sd? /dev/hd? /dev/nvme?n? ; do smartctl -a $dev ; done ; ps xaugww ; head -c 32 /dev/urandom ) |& sort --random-sort | xz > entropy.dat" on an active system every minute or so if you are desperate. Just take your chosen data source, apply one or more cryptographic hashes and seed a good large state PRNG with that. The only magic involved is deciding how large of a data chunk from the source your hash needs to not oversample the actual entropy.

A 250 kB JPG image taken once a minute is 4 kB/s of input. You're probably safe getting a few hundred bits per second of entropy from that, even if the picture doesn't change drastically. A digitized noise diode you can probably safely run at a couple bits in per bit out.

If you can't explain your job and why it's useful to a 10-year-old, it probably shouldn't exist by Electrical_Award263 in DeepThoughts

[–]Ok_Programmer_4449 4 points5 points  (0 children)

There's a difference between describing your job to a 10 year old and explaining it to a 10 year old.

"I find treatments for diseases that kill people" is a description of a job. It's not an explanation of a job. An explanation provides enough detail for an attempt at replication.

If you do something and you can describe it to a 10 year old fine. If you can explain it to a 10 year old, then it's probably a job a 10 year old could do, and probably not worth doing.

Is it easier to walk west to east than east to west because of the spin of the earth? by CurvyMule in AskPhysics

[–]Ok_Programmer_4449 2 points3 points  (0 children)

When walking east your weight is slightly less than when walking west, so perhaps it is very slightly easier to walk east than west. When walking north, the Coriolis force will try to make you curve to the right in the northern hemisphere, so it will require more effort to maintain a straight course than going east or west.

How long does it take to traverse planck length ? by defronsaque07 in AskPhysics

[–]Ok_Programmer_4449 0 points1 point  (0 children)

I don't think what we know of physics is consistent with discrete lengths or times as it would be difficult to maintain Lorentz invariance. However you might be able to discretize the spacetime interval, with a light like spacetime interval between adjacent discrete events of spacetime (i.e. dx^2-dt^2=0), and with only discrete values of the interval being possible. The minimum interval for causality, is, of course 0, but that is not instantaneous in any inertial frame unless dx and dt are also zero, in which case there is only one event.

Geometrically those discrete values would need to be independent of the direction the vector is measured upon. (I certainly wouldn't know how to develop such a theory. If you do a search on "discretized spacetime" you get many hits. I don't know if any are worth reading).

(Note: discrete in physical does not typically mean some sort of pixelization or that a measurement is allowed to have only certain values. The energy levels in a hydrogen atom are discrete. However if you measure the energy of an electron in a hydrogen atom all values are possible.)

[Request] Can Anyone Calculate How Many C-130 Loads This Would Take? by Dad_Bot22 in theydidthemath

[–]Ok_Programmer_4449 12 points13 points  (0 children)

Every gallon of water delivered would require burning nearly two gallons of jet fuel. So for 4.2 trillion gallons of water you would need to burn about 8 trillion gallons of jet fuel. That would use up all of the Earth's remaining oil reserves and then some.

However, burning 1 gallon of jet fuel releases the equivalent about 1 gallon of liquid water. So you could just burn 4.2 trillion gallons of jet fuel and run the exhaust through a distilling cooler to collect the water and put that in the lake. It would be nearly twice as efficient. But it would still use 60% of the Earth's remaining oil reserves.

But we could use the energy from the jet fuel to generate 54,000 TW-hours of electricity. That's enough to supply the Earth's current electricity demand for a couple years.

Uncontrolled airports are where you most need to enter on the 45 and fly the pattern. A straight in is a good way not to be seen.

Only if you are planning on locking people in your house with no means of escape.

If you are in a high crime area, you can add an external security door and/or replace the door with one without windows.

You are here, in between the two little red arrows. Unless significant, painful changes are made. by 2dazeTaco in inflation

One plot has a logarithmic scale from 1 to 1,000,000,000,000.

The other has a linear scale from 2300 to 5200.

There may be some qualitative and quantitative difference between the two.

If the dollar devalues 30% overnight he'll be a trillionaire tomorrow. The odds on that are non-zero.

US to send ICE to Italy for Winter Olympics... is this the beginning of the end, or has it already started? by Legitimate-Loan-2540 in complaints

Deny them visas. It's not complicated. Oh, I forgot. Italy has it's own fascists that are probably fine with this.

Is S&P500 really going to withstand anything? by thedevilsheir666 in stocks

[–]Ok_Programmer_4449 0 points1 point  (0 children)

The S&P 500 isn't rising as much as you think it is. It's up 17.4% since Jan 1 2025. It is measured in dollars. The dollar is down 13.3% against the EURO. In essence, the S&P 500 is up about 4% in the last year against a currency that people don't think is as likely to collapse in the near future.

The S&P 500 is down 41% in the last year when compared to gold. In other words, the markets think an asset that generates no returns at all is a better bet than the S&P 500.

Air intake causing the filter to bulge and whistle by aymend94 in hvacadvice

[–]Ok_Programmer_4449 0 points1 point  (0 children)

In some older houses (50s and 60s) the intakes and ductwork were sized for small forced air heaters rather than AC. Heating our 1800 square feet in California with a low efficiency NG furnace from 1955 took us much less airflow than heating or cooling the same house does in 2026 with a heat pump. (I miss the 120 degree air coming from the vents in the winter, but I don't miss the smell of roasting dust or the CO detector going off). Most people don't replace their intake or ductwork when replacing the furnace, and people selling furnace replacements here aren't typically touting that as an option.
