REISUB did not work all these days on Fedora 16 because it was not enabled. UGH.
See if it is enabled with
cat /proc/sys/kernel/sysrq
It will give you either 0 or 1.
If it is 0, enable it with:
sudo su
(enter password)
echo 1 > /proc/sys/kernel/sysrq
Next time your linux machine with Fedora 16 freezes or misbehaves in general, you are set to use the REISUB weapon.
Alt + PRTSC (or the SYSRQ key) +
R
E
I
S
U
B
-> issued in around 6 seconds with a second in between each alphabet.
Other ways to get around freezes and misbehaviour
Ctrl+Alt+Backspace: End the X session
Ctrl+Alt+F1 (or any function key from F2 to F6) followed by
ps aux or
top
find PIDs of processes
kill processes one by one with their PID
kill -9 PID-goes-here

Fedora 16 "Oopses" Category: linux
What irony. Just as I was trying to respond to (e:uncutsaniflush) about how he likes Fedora 16, my system froze up completely. First the mouse was still moving across the screen but I was unable to click anything. Then everything went unresponsive. I had to hard boot and then the whole system crashed. Splendid.
Take a look at the attached /var/log/messages. It found "oopses".
[txt]1211/Oopses.txt[/txt]
Where do I file such crashes and freezes? It is definitely a bug that either Fedora or Chrome people need to sort out. This has never happened in Fedora 15 which almost never crashed. Surely, this is a problem for many people? I have a feeling it is chrome-related because freezes and crashes always happen when I am on Chrome.
PS: (e:Paul): the txt attachments are broken. I tried pasting the log before in the message body and it did not work out. Some quirk made a zillion copies of my post. Every time I would click the edit button and submit some edits, it would make an extra copy and post it.
tinypliny - 12/12/11 10:56 % But of course, you knew all this so you don't need me to tell you.
heh, you overestimate how much I know. the truth is close to nothing. I am just barely getting by with all this linux mania. there is too much to learn and too little time.
systemd-37-3.fc16.x86_64 : A System and Service Manager
-- I disabled selinux long ago because it was annoying me.
-- My chrome has the following extensions:
Autocomplete
Delicious
Lazarus
Link Grabber
Middle Button Scroll
OWA chrome companion
Tab Glutton
None of them are for optimizing browsing. When I disable them, chrome starts even faster and pages load around the same speed.
I will try browsing without them today to test it out. Thanks for the suggestion.
-- How recently was the system updated as recommended?
Last week.
-- Are there packages held back?
hmm? what does that mean?
-- Are there packages from both stable and testing?
only stable.
-- Are there packages (especially kernel modules) compiled locally from 3rd party sources?
No, I didn't install any extra drivers this time.
-- Are there packages installed by force despite depends probs?
No. Whatever whined, I didn't install.
uncutsaniflush - 12/11/11 22:14 Oh yeah, are you doing selinux and something you use needs "readahead"? Sometimes selinux doesn't like readahead. I think I had that prob in Fed 13 or Fed 14. I don't think I fixed it, I just gave up.
I think there is a solution but I don't know what it is.
uncutsaniflush - 12/11/11 22:11 Back in the day when I was just a wee lad and liked breaking betas for fun, the big thing was being able to reproduce crashes and errors on demand to help figure out what is actually going on.
Historically, Browser extensions can be bugbears. I assume that you are using Chrome with extensions enabled. If a browser with extensions crashes or is suspected of causing crashes, usually the first thing to do is disable the extensions and try surfing the same websites that led to the original crash. If stuff crashes, its probably not the extensions; but if it doesn't it might be one of the extensions.
Additionally, in researching bugs and crashes, it is helpful to know how updated and how vanilla the running system is. How recently was the system updated as reccommended? Are there packages held back? Are there packages from both stable and testing? Are there packages (especially kernel modules) compiled locally from 3rd party sources? Are there packages installed by force despite depends probs?
But of course, you knew all this so you don't need me to tell you.
paul - 12/11/11 11:21 I will add the text thing back. I think I overwrite it when some resent updates got merged.
I don't see how the duplicate thing would happen.

Justin Bieber Category: music
What a beautiful voice and wonderful talent
turned into rot.
by fame.
PSL: I actually liked that Christmas song before I saw the video. One word. Ew. I guess Mariah Carey is more pleasant on the radio that on screen. And I don't even want to talk about that little sweet kid who is clearly being overproduced and droned over by pop. What a complete waste of his talents. It's painful to watch.
tinypliny - 12/11/11 11:19 I have to say though west 34th St is pretty magical (like consumerist crazy-buying magical). I went absolutely bonkers in the uniqlo store.
metalpeter - 12/11/11 10:30 It isn't product Placement in a Video the Video is labeled ad.... It is an ad for Macy's and it is his ad...
tinypliny - 12/11/11 09:27 Most music videos seem to require that all females be dressed like hookers
I don't know. Something about not being dressed like a hooker while singing christmas songs is a ton more appealing to me. You are singing a heartfelt sincere song, all the showing off and gestures seem out of place and context.
tinypliny - 12/11/11 09:23 The product placement on that video is atrocious. But then Christmas is clearly about consumerism.
metalpeter - 12/11/11 09:13 She does a great version of this song but when did Justin get added to it... Find the one of her alone it is far better..... She looks great but this out fit doesn't show off her boobs the right way?.... They are so trying to be like the Glee Version of this song .... And they Fail.... Can't say to much cause it is supposed to be an ad for a Charity Thing Macy's does or maybe for them and then you notice the charity still bad though....

Ha. Yours have just 4 arms?
Ours have 5x more arms and 20x hands.
Because we are better.
Made in China.
paul - 12/10/11 13:15 And this is exactly what scares me about China. That one doesn't even have a lot of arms compared to the crazy one.

Sad parrots Category: the odes
(e:pmt) and I went on a grand grocery shopping expedition. I got my favourite tea and so many greens! (e:paul) bought versions of all those greens for the tortoises. I guess we share the same diet, well... except murdered parrots.
I probably don't need to shop till next year, which is exactly what I wanted because I have some insanely intense writing sessions coming up. We also stopped at the pet store where we saw these lovely sad parrots.
This one looked at me in such a sad way. I was really tempted to buy them to get them out of that small cage. But I am not sure I am a "pet-person". I read that parrots require a ton of attention. Otherwise they become anxious and pick at their own feathers. She was nearly $1600.
This is the male from the same species called Eclectus, maybe because they are so eclectic and have such a sharp colour difference between the males and the females.
I can't believe how sweet that voice sounds!
(e:matthew) told me about the African Grey parrot and its famed intelligence. The poor thing was trying to sleep in another cramped cage.
I felt so horrible for them. Imagine being taken out of a tropical forest where you lived, shipped across seven seas in a cramped cage and landing here in snow-laden Buffalo... Can't be worse fates than that. I hope some rich person buys them and gives them a good home.
metalpeter - 12/10/11 17:35 Well maybe I wonder if since they repeat stuff if something like a radio or TV being on would give them that company they need.... You could maybe even mess with friends a bit.... Could they for example repeat Jokes.... How about chesy lines from porn? Maybe repeat the news?
