  In a scientific context, a hypothesis is a guess, based on current knowledge, including existing laws and theories. It explicitly leaves room to be wrong, and is intended to be tested to determine correctness (to be a valid hypothesis, it must be testable). The results of testing the hypothesis (i.e. running an experiment) may support or disprove existing laws/theories.

  A theorem is something that is/can be proven from axioms (accepted/known truths). These are pretty well relegated to math and similar disciplines (e.g. computer science), that aren’t dealing with “reality,” so much as “ideas.” In the real world, a perfect right triangle can’t exist, so there’s no way to look at the representation of a triangle and prove anything about the lengths of its sides and their relations to each other, and certainly no way to extract truth that applies to all other right triangles. But in the conceptual world of math, it’s trivial to describe a perfect right triangle, and prove from simple axioms that the length of the hypotenuse is equal to the square root of the sum of the squares of the remaining two sides (the Pythagorean Theorem).

  Note that while theorems are generally accepted as truth, they are still sometimes disproved - errors in proofs are possible, and even axioms can be found to be false, shaking up any theorems that were built from them.

  A law describes what happens, a theory explains why. The law of gravity says that if you drop an item, it will fall to the ground. The theory of relativity explains that the “fall” occurs due to the curvature of space time.

  If your computer is compromised to the point someone can read the key, read words 2-5 again.

  This is FUD. Even if Signal encrypted the local data, at the point someone can run a process on your system, there’s nothing to stop the attacker from adding a modified version of the Signal app, updating your path, shortcuts, etc to point to the malicious version, and waiting for you to supply the pin/password. They can siphon the data off then.

  Anyone with actual need for concern should probably only be using their phone anyway, because it cuts your attack surface by half (more than half if you have multiple computers), and you can expect to be in possession/control of your phone at all times, vs a computer that is often left unattended.

• ⁨Comment⁩ on ⁨Can you un-smart a smart tv?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:

  For what it’s worth, I just bought a TCL 55S450F (55 inch 4K HDR FireTV) specifically because it does not ever need an internet connection to function (expressly stated in the manual). It is currently on Amazon for $268 (they have other sizes at other prices). It’s a great TV, considering the price. The only real drawback for me is the remote is Bluetooth, rather than infrared (less compatible with universal remotes).

  Note that for full dumb TV effect, you’ll want to go into the settings and tell it to resume the last input, rather than going to the home screen when you turn it on (without connecting it to the Internet, the home screen is basically just a big banner telling you it’s not connected, and when you dismiss that, it just allows you to access inputs and manage settings).

  You are falling into a common trap. LLMs do not have understanding - asking it to do things like convert dates and put them on a number line may yield correct results sometimes, but since the LLM does not understand what it’s doing, it may “hallucinate” dates that look correct, but don’t actually align with the source.

• ⁨Comment⁩ on ⁨How do I "ls -R | cat | grep print" ?⁩ ⁨⁨10⁩ ⁨months⁩ ago⁩:

  grep -r string .

  The flag should go before the pattern.

  -r to search recursively, . refers to the current directory.

  Why use . instead of *? Because on it’s own, * will (typically) not match hidden files. See the last paragraph of the ‘Origin’ section of: en.m.wikipedia.org/wiki/Glob_(programming). Technically your ls command (lacking the -a) flag would also skip hidden files, but since your comment mentions finding the string in ‘any files,’ I figured hidden files should also be covered (the find commands listed would also find the hidden files).
