Perhaps it is, in your part of the world, but there's a reason why, even there, prisons are called "correctional facilities"; punishment is only part of the reason people are sent to prison.

Libav is a fork of ffmpeg, even if its developers, who are former ffmpeg develeopers, claim otherwise.

Libav proponents argue that theirs is the better fork.

Others say the opposite.

Trying to decide which fork to use, I read these two accounts and concluded that both(!) were saying "stick with ffmpeg". If you are interested in the issue, read these two references and decide for yourself.

I installed Cinnamon the other day, and was almost tempted to switch to it from KDE, so I fail to see what's all this fuss about Gnome 3. Isn't that what Cinnamon uses under the hood?

(What do you mean I'm supposed to use Gnome 3 without Cinnamon?!?!?)

Does this method scale to learning more than one password, or does one have to use the same password everywhere? What about changing one's password?

Regarding coercion, it is often more effective to threaten someone's family than to threaten that someone. This method does not seem to offer protection against this kind of coercion.

Hmm, now that you mention it, I see that the solution in the article's comments is also wrong, as cell D6 has a value of 3. instead of 5. Perhaps the puzzle does have only one solution, after all, and this is why most of my runs produce the same result.

It looks like this puzzle is one of the hardest to type, if not to solve!

Here's one:

812 753 649
943 682 175
675 491 283

154 237 896
369 845 721
287 169 534

521 974 368
438 526 917
796 318 452

And here's another:

869 712 354
243 658 179
175 493 286

952 367 841
316 845 792
784 129 635

531 274 968
428 936 517
697 581 423

The list is not exhaustive.

When I wrote my reply, I got a second solution after two additional runs on the solver. Now that I actually want to reproduce a second solution, my solver kept producing the same solution, so I helped it a bit by filling in an additional cell! (It's the"2" in the second row—"1" did not work.)

If your solver does not make random guesses, making its guesses in some deterministic fashion among valid choices (e.g., in order) instead, then it is obviously not wrong! On the other hand, I think it is fun to be able to let the solver loose on an empty sudoku grid and watch it produce a different solution each time.

One reason that you cannot solve this puzzle without making assumptions is that it has more than one solution!

One of the comments in the FA provides a solution to the puzzle, which is different from the solution I found using a sudoku solver that I wrote back when I realized that I was spending too much time on these puzzles.

When stuck, my solver starts selecting random values among the valid possibilities, backtracking if the guess does not lead to a solution. This makes it possible for the solver to solve puzzles that don't have enough (or any) numbers to solve the puzzle deterministically, producing different answers each time it is run on such a puzzle. I guess this particular puzzle is one such incomplete puzzle, as running the solver again, produced a third solution!

I would think that sudoku puzzles with more than one solution are not correct puzzles, so this particular puzzle does not qualify as such.

a set of six pyramid-shaped probes

So that's what the title of the Doctor Who episode was referring to! I wonder if the probes will locate Sutekh.

Now, this is very interesting: Do you see UV as just more purple, or do you see it as an entirely different color, that you cannot describe to people who cannot see it, just as they cannot describe purple?
