How can I check the version of the installed Apparmor on a Linux system?
I would like to know how to get the version information of an installed program that doesn't have the      --version or -version   method implemented.
Do you have to want to hurt someone for the cruciatus curse to work? OK so the scene where Harry sees Voldemort making Draco tutur Rowel brings a few questions to my mind.      he felt the rage that did not belong to him posses his soul, saw a long room, only light by fire light, and the grate blond Death Eater on the floor,screaming and writhing, and a slighter figure standing over him, wand outstretched, while Harry spoke in a high, cold, merciless voice.   "More, Rowel, or shall we end it and feed you to Nagini? Lord Voldemort is not sure he will forgive you this time...You called me back for this, to tell me Harry Potter has escaped again? Draco, give Rowel another taste of our displeasure... do it, or feel, my wrath yourself!"   A log fell in the fire: flames reared, their light darting across a terrified, pointed white face-   I remember in the Order of the Phoenix Harry tries to do the cruciatus curse on Bellatrix, it doesn't work. She say this is because Harry doesn't mean it, he doesn't want to hurt he enough. If she's right about that (I'm sure she is) I don't see how Draco is managing to make to make Rowel writhe and scream, because it is clear he doesn't want to be doing it.   Also Harry was actually angry at Bellatrix and if his anger at her killing his godfather won't work... well you get my drift.   I know Draco is probably better at magic, but I feel Bellatrix is right, you really have to want them to hurt for it to work.  Next thing, Voldemort's having Draco do it why? Is he doing to upset Lucius, because that and lot of effort to go to, seeing as Voldemort is angry and he'd probably do a better job himself. Or is he trying to train himself a new soldier, I mean the other ones are getting old. Fantasy series with Celtic overtones, intermittent stone magic, and ongoing slow magic I checked this series out of the library during college, maybe 15 years ago now.    It was based around 'stone magic' – magical stones that granted their bearers enormous power.  Unfortunately, the power of these stones is intermittent, they'll fade out for a long time then fade back in.  The main characters dealt with a 'master' stone of some sort, the first to restore, last to die.  It's also the key to granting other people access to their own powers – I think seals had magic fish they swallowed, which keyed off the master stone, and in the last book I think the character created magic staves for another race. It also had 'slow magic' – longer to set up, less apparently potent than stone magic, but the slow magic, given time to work it, could still be powerful and dramatic.  It just took time and preparation instead of brute force. In one book, the main character faces off against the source (or something like that) of magic, and is about to win when it's discovered she's pregnant.  The source – a dragon? – isn't allowed to harm anyone who doesn't come to it freely, so the main character is forbidden to finish the trial.  In the sequel, her daughter repeats the trial, and becomes immensely powerful by winning, but there was a cost of some sort, something that transformed her A lot of the naming made me think it had a Celtic root. What is 'Currying'? I've seen references to curried functions in several articles and blogs but I can't find a good explanation (or at least one that makes sense!) Where can I find out when the next kernel version will be released for my distro version? I checked the , , and  wiki pages but still cannot seem to find a complete answer to this.  When using an LTS release like 18.04, is there somewhere public that can be checked to determine what kernel versions are being tested and when they are anticipated to be released for it? I would like to use 4.19, for example, but would like to know how to check this for any anticipated kernel release.  I know I could potentially just install the 4.19 kernel myself but I would rather know when it (and future kernel releases) were in the release pipeline. Is there somewhere on Launchpad that I could check? Somewhere else? Where are the Ubuntu kernel package maintainers doing their work? Mail on Big Sur does not reliably find dollar values Process management and high technology weapon. Novel name and author? I am looking for help to point me out at a very old novel (likely from the '60s) about two empires at interstellar war. When it comes to starships, one is technologically very advanced, and the other has very low and inefficient technology.  The highly advanced empire has apparently strong chances to win the war, in particular considering a new technology they were developing. I remember the technology to work like this: consider the space as a flat surface, and on this surface, a disk around the spaceship. When the technology was turned on, this disk was stretched out, as made of rubber, so that it produced a cone, with the tip being the spaceship. The spaceship was therefore teleported 10 parsec away (if I remember correctly), but retained all the connections to the original position. If the spaceship moved, the cone moved as well. This allowed to move in position among enemy ships completely unnoticed, by stretching while afar, then moving in the proper position 10 parsecs away, then destretching.  Despite this technology, the empire lost the war because of delays. It's a perfect example of how having a disruptive technology does not guarantee to win against the competitors.  I am trying to find out the author and name of this novel, hopefully with the date of publication and in which journal/magazine. How to calculate what this power series converges against? (double factorials) Delete files except n files with the "bigger" name? I've been getting this undefined symbol building with this command line:  $ gcc test.cpp Undefined symbols:   "___gxx_personality_v0", referenced from:   etc...   test.cpp is simple and should build fine.  What is the deal? Did the law of conservation of energy apply to the earliest moments of the Big Bang? If so, what theoretical physics supports this?   I hear that Einstein's theory of relativity disputes the law of conservation of energy- so does that mean the law is false, or only some aspect of it? I have, by default, 250MB of swap space in Ubuntu, and I want to expand it to a larger size. I need 800MB, which I think will be enough to open several applications without having to hit the current limit of swap. I hope someone can help me. Problem printing LaTeX from lua in lualatex How can I disable animation when switching desktops in Lion? I would very much like to disable the sliding animation that occurs when switching desktops via ctrl+&#x2192;/&#x2190; or ctrl+[number] in Lion.   This was previously accomplished in previous versions with this command:  defaults write com.apple.dock workspaces-swoosh-animation-off -bool YES &amp;&amp; killall Dock   This new animation is even more slow than in Snow Leopard - nearly 1 second to switch - a real productivity killer.

I know the relations between the two countries are bad.   Is it likely that I'm not allowed to enter the USA after having been to Iran?   If it matters, I've never been to either of those countries.
