but the few things I get to understand (or sort of understand) are such a snap at reality, almost metaphysical, and a bit weird to think so many people are walking around and have no clue as to how some things really work
@Zanna I think I got a bit more curious about it after watching Interstellar (personally one of the best movies I've ever seem, and I liked it even more when I read that most of it is based on real physics theories)
even vaguely correct physics in movies is gratifying to me, like in the recentish Star Trek movie that had a huge explosion is space with no sound, I sat back with a happy sigh hahaha
Someone gifted me a book about, what's it called? Climate engineering... stuff like dumping iron in the ocean or deliberately polluting the air to reduce global warming... the most evil bunch of junk I can imagine. I didn't even open the book, and I couldn't give it away, I dropped it in the recycle bin
I can't read scientific papers, I am bored by the 7th footnote.
@edwinksl you were talking about how math is the currency of physics, but I don't know if that's just my impression, aren't the frontier physics theories mostly backgrounded by speculation over qualitative data and not quantitative?
@Zanna @edwinksl en.wikipedia.org/wiki/Brane_cosmology - That's the theory that I was reading on how could gravity travel past other dimensions. It claims other forces are constrained to our spacetime, while gravity is not, explaining why it's a weaker force (since it leaks to other dimensions)
@Zanna @edwinksl Don't take all I'm saying as true, it's just what I understood. But most particles that carries forces (electromagnetic, light, mass) have been found, except for a particle that carries gravity (they would name it gravitron). Gravity compared to other forces, at least on macroscopic scales, is weaker. So this theory claims gravitrons are not constrained to our dimensions (3 spatial + time), but could travel to other dimensions explaining why we couldn't find gravitrons yet
"Even though there are only five superstring theories, making detailed predictions for real experiments requires information about exactly what physical configuration the theory is in. This considerably complicates efforts to test string theory because there is an astronomically high number – 10500 or more – of configurations that meet some of the basic requirements to be consistent with our world."
If a question:
is an exact duplicate of an existing question, even confirmed by OP
is also meant in the same way
...it seems pretty clear that the question should be marked as a dupe. Additional (alternative) answers should be posted on the original question. If OP does not like the existing ...
@JacobVlijm sorry, but that's what appears to be the case here. Your suggestion to edit dupe messages for all questions because of that one post does more damage to AskUbuntu.
@JacobVlijm As for "couldn't draw votes to his answer" it's totally OK , and understandable. I get that, really. If you're upset about that, sorry. That just seemed to me to be underlying reason. I apologize
@JacobVlijm there have also been posts on meta.stackexchange.com about this before, so i will link them in a minute or two.
How to create memory dumps for out of memory.
If system is out of memory then oom-killer kills the process which occupies highest memory by some calculations.
How can we get core dump of the process killed
@Serg I don't think it is a very bad behavior until he doesn't do this annoying. The SE model actually likes the active investigations around a question.
@peterh it is not bad behavior, I totally understand that. Everybody wants more attention to their posts. But to change the way duplicates work just because of that - no ,sorry, this only puts other users in disadvantage.
SIGKILL. Signal #9. Killed. Means the process got killed by the kernel (forcibly) with no chance for the process to say, "No-no-no-no, wait! I want to live!"
@Serg If he asks essentially the same question multiple times, they can be closed from the second. But, if he asks essentially different questions around the same topic, I think it is a positive thing and not negative.
IIRC the command stream verifier in the open source graphics stack will issue SIGKILL to a process using OpenGL that submits an invalid command stream to the driver
@Jodamo117 You get the freedom, this compiz-crash-with-SIGILL means that the 3d accelerating window manager crashes on some reason, and the most probable reason is that the 3d driver is buggy :-(
@allquicatic Not SIGKILL, but SIGILL. Signal on "illegal instruction", i.e. the code segment of the compiz is harmed...
I knew SIGILL in the back of my mind but haven't seen that except when trying to run invalid code :P
actually, compiz -> libgl (Mesa) -> llvm -> codegen stuff... could result in an illegal instruction as part of LLVM JIT compiling instructions at runtime
especially if using a driver that is implemented via Gallium
@Jodamo117 1) Try to update your 3d driver 2) Try to disable 3d accelerating functions of your window manager 3) Try to switch to another driver (in many cases, there are a binaryonly driver from the nvidia/ati having hardcore hw acceleration, and an opensource one, having fewer 3d accel, but being opensource) 4) You can buy a not so evil hw from a different amnufacturer
@Jodamo117 5) you can switch to a window manager not using any 3d accel 6) you can check for hw problems, for example memtest or trying some massive 3d using app to check if it dies even with that.
7) you can use a (3d/compositing) window manager that isn't using compiz, maybe its code path won't hit the bug you are experiencing, even keeping the same graphics driver
@peterh not sure it's compiled using llvm (clang); it's probably compiled using gcc, but under the hood Gallium3d uses libLLVM at runtime to generate code... though, now that I think about it, I don't recall if it exclusively uses LLVM to generate code for the GPU, or if it also generates CPU-side code using LLVM.
looks like his computer comes with some nvidia GPU; I guess it depends on whether he's using the iGPU or dGPU for the desktop which driver is being activated
@peterh Sun got bought out by Oracle; that's what happened
as they demonstrated by suing Google, the fact that Oracle released Java under an "open source" license doesn't stop them from attempting to cash in whenever someone uses Java stuff -- even OpenJDK stuff -- in other projects
@peterh no, the Jonathan Schwartz led Sun of the mid 2000s was basically the ideal commercial open source company; it just took them a very long time to fully commit their mindset to being a good open source citizen
right before they got bought by Oracle they were pretty much there
@allquicatic What happened to the redhat-oracle marriage? As I know, next to the redhat, the IBM and also the Oracle have their nearly-unknown distributions, wtf?
@peterh ew , java ? Also If he asks essentially the same question multiple times, they can be closed from the second We're not talking about one OP posting same question. We're talking about a person who comes to the site and sees that their question is being closed. They'll be like " But guys, those posts don't work for me ". And the close voters basically say "Screw you, we close everything as duplicate, even if it didnt work for you"
@peterh Red Hat had better not have anything to do with Oracle; I've never heard of them potentially merging and I'm glad they haven't; Oracle is as evil as could be and Red Hat is pretty much non-evil
@Jodamo117 Nah, you need to understand the physical layout of your computer :) You have ports that are on your motherboard, and then you have ports that are on your expansion cards --
look at that picture of the back panel... the motherboard ports are clustered on the left-hand side in a tight "box" (rectangle), whereas the expansion card ports are in removable slots along the bottom
@Serg I wish you'd stop suggesting that it is: And the close voters basically say "Screw you, we close everything as duplicate, even if it didnt work for you" Really. Also only very new users cannot comment etc.
if you have the monitor plugged into the motherboard, it'll be using the integrated graphics core on your CPU, which is a tiny fraction of the performance of whatever dedicated GPU you have in the expansion slot along the bottom
@peterh exactly that. Especially on stackoverflow. I liked AU because it's more friendly and people communicate here a bit better, but lately it's just been getting a bit worse - people abuse close vote and downvote too much
ok... well, Ubuntu always tries to start you off with the open source graphics stack, so maybe you can drop to a terminal and install the proprietary nvidia driver, it'll work better
I suppose that issue would be extremely likely to happen if you are using a GTX 1060/1070/1080, because the new cards have quite limited (incomplete) support in nouveau
@allquicatic would I do that from Ubuntu? Because It wigs out before I can do anything. though i hadnt tried to hot key terminal when it was doing that yet
@Jodamo117 of course - you can't do anything to it from Windows... well, you could, but it would be painfully hard
you could also plug your monitor into the motherboard instead and use the Intel iGPU, which might at least temporarily let you into a bug-free desktop long enough to install the Nvidia driver and reboot
@Serg 5 determined 3k+ users could reopen daily around 40 unfairly closed questions. In the only one case it happened, the mods started to give some 1y cage, but I am not sure it should happen again.
@allquicatic They laid them off???? Wow! They are really psychos then. I've heard they got "other tasks" from their employer, not in the java development.
@allquicatic I suspected, it is essentially a threat for the google, to "help" the java development, if he makes such a lot profit from it. And, the google can threat back with the go, but it is not a really strong threat, because the developers learned java/android won't be happy to switch to go. Many of them would switch to the m$ or to the ios. Particularly in the US.
@Serg Maybe a "question reopen" chatroom could be started, where everybody could post his/her question nominated for reopen. And people having 3k+ on the given site, could decide if he supports the initiative or not.
@Serg I've heard once from a similar initiative, but into the other direction: a "delete voters" chatroom has once existed. Then the founder got a 1y ban and he didn't came back. It seems the SE don't like the cooperations.
@allquicatic What if google would buy Oracle?
@allquicatic Well, I think it is forbidden by the U.S. anti-trust law. Somehow naming an OS from a furniture, or from a fruit, and then banning every product even with a similar name, it wasn't... suck US
@peterh Huh? Just... "Huh?" in general to your last several comments. I'm really not sure where you're going with all this. And no, Google could never buy Oracle. Not going to happen.
And the lawsuit between Google and Oracle over Java has nothing to do with trademarks.
@allquicatic I think, they want money and don't know, how can they get it. Maybe they repented that java has been opensourced. But I am sure, if it hadn't been, it would be much smaller now. And the also Android would be much smaller, and it would use probably a go-like api.
