ChatGPT to the rescue. Here is the shorter synopsis.... still crazy but at least it's understandable now.
> The metaphor: if you were going to pick up (or “take”) your penis with something as thin and fragile as rolling paper, you’d better be very careful — otherwise you’d tear it, risk injury, etc. That imagery is deliberately hyperbolic and somewhat bawdy, which fits the nature of many Spanish idioms.
> Over time the expression morphed into the figurative sense rather than the literal. Some sources note that the exact phrasing is “cogérsela con papel de fumar” rather than “coger con…” etc.

Not sure you understood my mention of X. I see it as outdated and don't care about it. You are suggesting you can capture single screens on Wayland, but I am specifically referring to being able to "snip" like in the modern sense of screen capturing.
Most people are capturing parts of the screen, and not all of it. I don't buy having to use an editor after the capture as acceptable.

Does it support labwc? The web page says something about legacy windowing system, so I'm guessing it's still only expected to work under X.
Also, my understanding is that there is no wayland screengrabber that isn't limited to taking an image of the entire desktop space (even if multiple monitors... then you get a reeeaaallllyyyy wide png).

There is one. I forget the term, but it is about interrupting looping thought processes.
Basically choose a random letter in the alphabet, or a word with lots of different letters in it (so not "visibility") and then go letter by letter thinking of words with that initial letter. For each letter, go until you can't really think of more, and then move onto the next number. Continue the moment you can't tihnk of another word... it's not about stressing yourself out.
This makes it pretty much impossible to think of things that keep you awake (problems, negativity, etc), and your brain gets super tired of thinking up randdomish words that have little to nothing to do with each other.

Do you have the equivalent of a Tax Free Savings Account like we have up here in Canuckville? I have, and use it for the obvious enough reasons. But (thankfully) I read an article that if I buy/sell too quickly, they assume I'm a day trader, and immediately classify it as income.

It's really frustrating, because "Liberal" means such different things to other countries.
For Canada, the crazy fascist wannabes are strongly connected to the conservatives on the far right, whereas Liberal tends to be leftward. Eventually you reach tree hugging leftism like NDP and whatnot.
Totally different use of familiar titles.
We also have that same thing when talking about "tories" etc that bear so little similarities to our local divisions using the same descriptives.

This reminds me of the black fax attacks in the 90's (and probably earlier). To protest governments, people would send them hundred page faxes that were entirely black, which of course created a real cost for the department under attack, and kept the device unavailable for legit purposes.
Blindly letting outside people print anything out on your paper (fax or printer) is not exactly smart these days.

Some of our Premiers, which are like Prime Ministers, but at the Provincial level, are highly guilty of catering to corporate interests. Ontario's current PM is a sucker for the almighty dollar, and enriching his friends and business partners.

Yea the parliamentary system works well, which is why we're happy to keep it. This might change depending on how the current king, and future king(s) are accepted by Canadians. As you know, Britain's been having a tough time keeping their colonies connected to the Crown.
There is a type of authority, because federal laws are presented to the Queen (King nowadays) via the Governor General, who then returns with the Royal Assent. And when government is prorogued or dissolved, they "give permission" from the Throne. They also deliver the Speech From The Throne. But this is pretty much all symbolic, and executive in nature. The word "advice" is used a lot.
That is to say, things can't be done without the Governor General's involvement, but it takes a lot for the GG to deny the PM's wishes... last time it happened was in 1926 when Canada was a very different place, and our connection to the monarchy was much stronger. All hell would break loose if Canada wanted something that was denied by the Crown.
In practice, it's a sort of pomp and circumstance thing.

You have a black shirt. After AI you have a black shirt with exposed bra. Ask yourself if it's appropriate to add a bit of bra not knowing if it was there in the original picture. Since you don't know, you either try to find out, or you don't use that added detail.
The solution is the same as when we instruct people to verify their sources when they nab stuff from Wikipedia. No difference at all. If you can't verify the source, you don't add the detail.
The AI just did what it was asked. There is nothing to change there. There is something to change with the users who blindly accept new facts or image elements.

Here's something I talk a lot about.
The Pseudo Random Number Generator (PRNG) is ultra important in encryption when handled by computer.
I learned the easiest way to tell whether your PRNG is any good is to take 3 bytes from it, plot them as X, Y and Z, rinse, repeat, and then just look.
A good PRNG will look like an even fog. A crappy one will have visible features.
You can replace the bad_prng_1 and bad_prng2 functions with your prng to see if it is any good.
<code>import random import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D def good_prng(): # Generate three independent random bytes x = random.getrandbits(8) y = random.getrandbits(8) z = random.getrandbits(8) return x, y, z def bad_prng_1(): x = random.getrandbits(8) # Introduce patterns for certain ranges of x if 50 <= x <= 100: # Create a pattern with some randomness y = (x * 2 + random.randint(0, 15)) % 256 z = (x * 3 + random.randint(0, 15)) % 256 elif 150 <= x <= 200: # Another pattern y = (x * 5 + random.randint(0, 15)) % 256 z = (x * 7 + random.randint(0, 15)) % 256 else: # Random y and z y = random.getrandbits(8) z = random.getrandbits(8) return x, y, z def bad_prng_2(): # Generate x, y, z such that x + y + z is constant total = 384 # For 8-bit numbers, 128 * 3 x = random.getrandbits(8) y = random.getrandbits(8) z = (total - x - y) % 256 return x, y, z def main(): # Number of points to generate num_points = 10000 # Prompt the user to select the PRNG type print("Select PRNG type:") print("1. Good PRNG") print("2. Bad PRNG 1 (Patterns in ranges of x)") print("3. Bad PRNG 2 (Sum of x, y, z is constant)") choice = input("Enter 1, 2, or 3: ") if choice == '1': prng_function = good_prng print("Using Good PRNG...") elif choice == '2': prng_function = bad_prng_1 print("Using Bad PRNG 1...") elif choice == '3': prng_function = bad_prng_2 print("Using Bad PRNG 2...") else: print("Invalid choice. Defaulting to Good PRNG.") prng_function = good_prng # Keep track of plotted points points_dict = {} x_vals = [] y_vals = [] z_vals = [] colors = [] for _ in range(num_points): x, y, z = prng_function() point_key = (x, y, z) if point_key in points_dict: color = 'red' else: color = 'black' points_dict[point_key] = True x_vals.append(x) y_vals.append(y) z_vals.append(z) colors.append(color) # Plotting with Matplotlib fig = plt.figure() ax = fig.add_subplot(111, projection='3d') # Plot the points ax.scatter(x_vals, y_vals, z_vals, c=colors, marker='o', s=2) ax.set_xlabel('X') ax.set_ylabel('Y') ax.set_zlabel('Z') plt.title('PRNG Visualization') # Show the plot plt.show() if __name__ == "__main__": main() </code> Feel free to post screenshots of what you get with your prng. Most new algorithms will look pretty much the same, but I bet a lot of old ones look interesting. And as you can see, the bad ones really stand out.
The input is just a stream of pseudo random bytes that can be treated in sets of 3 to create 10,000 points on the plot. The colour changes if the same 3 appear again. It does happen sometimes.
There is a delay to plot (for obvious reasons) but you can drag it around to see it from different angles.

Ritalin for children has been a thing since at least the early 70's when there was a drug for everything, and everyone took them unquestioningly.
EDIT: Except for autism. If you weren't spinning dishes on the kitchen floor, you were not autistic. Pretty weird that you had to be totally non-verbal and totally withdrawn to get a diagnosis for that.

It's ironic, given how they really pushed Ritalin on children back in the day.
If you were diagnosed as a child, you're a shoo-in as an adult. Perhaps tell the specialist you were diagnosed as a child, but your parents were against you taking meds for it.
