| 00:33 | <@Consul> | Okay, that's the second time my computer's powered down suddenly of its own accord. |
| 00:33 | <@Consul> | I can't think of what would be causing that? Overheating, maybe? |
| 00:35 | <+Alek> | probably. |
| 00:35 | <+Alek> | vid card is likely. |
| 00:36 | <@Consul> | Hrm, built-in video, but I could get a cheap vid card if that's the issue. |
| 00:36 | <@Consul> | The computer boots right back up afterward. |

| 00:42 | <@Consul> | Hrm... |
| 00:42 | <@Consul> | The Echo sound card is new... |
| 00:42 | <@Consul> | Maybe that has something to do with it... |
| 00:46 | <@Consul> | Hrm, the clues online seem to point most to an overheating CPU, which is possible. I just have the no-frills fan that came with the CPU on mine. |
| 00:58 | <@Consul> | Hrm |
| 00:58 | <@Consul> | Core 1 hovers about 6C higher than Core 0 |
| 00:58 | <@Consul> | Core 0 at 42, Core 1 at 48 |
| 00:58 | <@Consul> | A bit on the high side, probably. |

| 01:06 | <@Consul> | Very intersting... |
| 01:06 | <@Consul> | So far, both sudden shut-offs have been while watching a Youtube video. |
| 01:08 | <@Consul> | Query: is it possible to misconfigure a Linux kernel that some combination of hardware/software might cause a spontaneous shutdown? It's a total shutdown, like pulling the plug, not a controlled halt. |
| 01:08 | <@ToxicFrog> | Probably. |
| 01:08 | <@ToxicFrog> | I wouldn't know how, offhand. |
| 01:09 | <@Consul> | Well, this has been happening since I loaded this newest Ubuntu Studio, and as you know, it's had a shitload of bugs. |
| 01:09 | <@Consul> | I'm going to dump it this weekend when I have time to try Gentoo again. |
| 01:10 | <@Consul> | In the meantime, I'll stop visiting YouTube and see if it happens again. |
| 01:10 | <@ToxicFrog> | Speaking of which, I need to get openSUSE on Orias at some point |
| 01:11 | <@Consul> | I just want something that's never touched PulseAudio. |
| 01:12 | <@ToxicFrog> | Yeah, I'm not suggesting it for your purposes |
| 01:12 | <@ToxicFrog> | I just like it more than Fedora now |
| 01:12 | <@Consul> | Gentoo is difficult for me to get to a usable level, though. |
| 01:12 | <@Consul> | Something always goes wrong. |
| 01:13 | <@ToxicFrog> | Might try Lunar, which is a source-based distro I find better than gentoo in general |
| 01:13 | <@ToxicFrog> | I haven't used either heavily, though |
| 01:13 | <@Consul> | Nice to know the options. |
| 01:13 | <@Consul> | I tried Arch a couple of times. Lots of potential, but again, I found it difficult to configure Gnome and X in a way I liked. |
| 01:14 | <@Consul> | I guess that's going to be an issue on all of these "meta"-type distros, though. |
| 01:25 | <+Alek> | ehh, 48 is normal. |
| 01:26 | <+Alek> | 60+ is something to worry about. |
| 01:27 | <+Alek> | could be memory overheat, but memory tends to cause a freeze, not a reboot. |
| 01:27 | <@Consul> | Well, it's not a reboot, it's a cold shutoff, like the power plug is suddenly pulled. I still had an Ethernet light on the back jack, though. |
| 01:28 | <@Consul> | So the mobo was still getting power. |
| 01:28 | <@Consul> | Definitely sounds like some failsafe is getting tripped. |
| 01:30 | <@Consul> | Aha! My hard disk is hovering at about 44C and it's throwing a red light in ksensor. |
| 01:31 | <+Alek> | now that's worrisome. |
| 01:31 | <@Consul> | The other two hard disks are hovering about 40C |
| 01:31 | <@Consul> | Time to get a case fan. In the meantime, I'll start shutting my comp down when I don't need it. |
| 01:34 | | * Alek has 2 case fans and keeps both side panels off. hasn't had an overheat since. :P |
| 01:35 | <@Consul> | I could pop my side panel off for now, I guess. |
| 01:35 | | * Alek had, prior to that, a string of overheated-gpu cold shutdowns that culminated in a burned mobo, then in a flared-out transistor on the video card after mobo replacement. |
| 01:36 | | * Alek has a different vid card now, of course. |
| 01:37 | <+Alek> | it was epic. I finish assembling the case with the new mobo, everything in, all cables hooked up. I flip the switch, and a second later there's a HUGE flare reflecting off the wall the left side of the case is facing. I take a look, a component on the vid-card is flaring like a road flare. bright and steady. |
| 01:38 | <+Alek> | I flip it off immediately, let it cool down (just in case) and take out the vid card, and use the onboard... until I put in the other card. |
| 01:38 | <+Alek> | that solved everything. >_> |
| 01:40 | <@Consul> | Yeah, all three drives are over 40 now. |
| 01:45 | <@Consul> | I just got a small fan and put beside the comp to blow right on the drives. |
| 01:46 | <@Consul> | Looks like it's working. Down to 42... |
| 01:46 | <@Consul> | 41... |
| 01:48 | <@Consul> | And 40... It's not blinking at me anymore. |
| 01:48 | <@Consul> | Hopefully, this is the issue. |
| 01:48 | <@Consul> | If I still get spontaneous shutdowns, then I'm back to square one. |
| 01:54 | <@Consul> | Down to 37. So far so good. |
| 02:02 | <@Consul> | Is it normal to have an 8 or so degree difference between CPU cores? |

| 02:40 | <@gnolam> | 40 C is nothing... |
| 02:40 | <@gnolam> | As long as you're within human temperature ranges you have nothing to worry about. |
| 02:41 | <@Consul> | It could be GPU then. |
| 02:41 | <+Alek> | hee |
| 02:41 | <@gnolam> | (Of course, in my experience, computer sensors tend to be /wildly/ inaccurate) |
| 02:41 | <@Consul> | I'm trying to find a way to get to that temp sensor... |
| 02:46 | <@gnolam> | I should really try to fix the overheating issues on this computer. |
| 02:47 | <@gnolam> | Having to open all the windows every time I want to do heavy computations is getting a bit stale. :) |
| 02:48 | <@Consul> | The sudden shutdowns are very disconcerting, because they're so hard to diagnose. |

| 20:38 | <@Consul> | Well, I think I nailed down the cause of my spontaneous shutdowns. |
| 20:38 | <@Consul> | I pulled my new sound card, and guess what? |
| 20:41 | <@AnnoDomini> | BUGS. |
| 20:44 | <@Consul> | Well, there is still one test: plug it into the other PCI slot. |

| 23:08 | <@ToxicFrog> | <himi> What book/books would you recommend for me as a reference/learning tool for C++? |
| 23:08 | <@ToxicFrog> | * himi has been dragged into a project involving modifying some large C++ codebases, and would like something to help him out |
| 23:09 | | himi [~fow035@Nightstar-13747.lns1.cbr1.internode.on.net] has joined #code |
| 23:10 | <@AnnoDomini> | The Necronomicon, in the original. The sanity loss from that should get you going smoothly towards adopting the C++ mindset. |
| 23:11 | | * himi snickers |
| 23:11 | | * Vornicus hasn't seen a useful C++ book. |
| 23:12 | <@Consul> | Neither have I. I suppose I could always say "can't go wrong with O'Reilly", which might be true in most cases... |
| 23:13 | < himi> | I mostly just need a reference - I'm already a competent programmer in a number of other languages both OO and non |
| 23:14 | <@Consul> | Well, in that case, you probably can't go wrong with O'Reilly. |
| 23:16 | < himi> | There isn't a good equivalent to K&R? |
| 23:19 | <@ToxicFrog> | No-one actually uses K&R C anymore, so possibly not the best analogy~ |
| 23:20 | | * himi was talking about the book . . . |
| 23:36 | <@TheWatcher> | If you really like pain, you could try Stroustrup... |
| 23:36 | <@TheWatcher> | But that won't cover a bunch of stuff, especially Boost. |
