Re: Okay, I confez, I'm not a Linux Adapt.

Mentioned this once before on the forums and stumbling over a blog article on Ksplice http://blog.ksplice.com/ , the boot-less kernel patching tool. Following the path down to the download links for the free versions for Ubuntu and Fedora, it appears to already been included in the Ubuntu 10.10 Synaptic Package Manager, version 0.9.9-2
Ksplice allows system administrators to apply security patches to the
Linux kernel without having to reboot. Ksplice takes as input a source
code change in unified diff format and the kernel source code to be
patched, and it applies the patch to the corresponding running kernel.
The running kernel does not need to have been prepared in advance in any
way.

Go and grub it.

PS, more goodies on that blog... e.g. network discovery and configuration, DHCP, DNS and the lot.

Edit: proofs the downloadable version from Ksplice is quite a bit further along @ 1.1.32. Installed it and it went to check for any kernel patches and reported none were needed. An menu entry is created on the Systems Tools menu for Ubuntu 10.10.

Edit: Every so amazing this Ubuntu business. When first installing 0.9.9-2 from Synaptic and going back in there, there was a New in Repository and 3 packages listed there for Ksplice, version 1.1.31. Ran that and it even showed the free access key that was assigned. I'm rolling, bootless.... MS got a few lessons to learn for applying security patches ;P

Re: Okay, I confez, I'm not a Linux Adapt.

"To apply a patch, Ksplice first freezes execution of a computer so it is the only program running. The system verifies that no processors were in the middle of executing functions that will be modified by the patch. Ksplice modifies the beginning of changed functions so that they instead point to new, updated versions of those functions, and modifies data and structures in memory that need to be changed. Finally, Ksplice resumes each processor running where it left off."

That's why there's no soft reboot bootstrapping required.

Re: Okay, I confez, I'm not a Linux Adapt.

Thanks for that. Ksplice reported 2 days ago that my latest kernel upgrade to 2.6.35-27.bld 48 was "not yet" in their db, but today the yellow triangle on the panel status icon went away and status reported as nominal/up to date, so it's working to satisfaction this far.

Discovered some glibc troubles today which had been there since Feb.20 and only showing in DDDT2 result logs [still validating], applied the temporary fix of adding a line to /etc/profile of export MALLOC_CHECK_=0, which removed the alerting messages and noted that it may have relation to NVIDIA drivers and or OpenOffice ... actually removed that and had installed LibreOffice 3.3.1 from Synaptic on 10.10 so will see if it returns. It's said it could have the inverse effect on the next update, then requiring for the line to be removed again. We'll see... the fix did not affect the performance... still crunching at 99.8% efficiency if left alone and the GUI/x-org has been stopped.

Kind of eager to actually put me hands on the first RC of Natty as some major performance enhancing reworks are coming in there and the next 2.6.39 kernel.

Re: Okay, I confez, I'm not a Linux Adapt.

This is so hilarious... have me Linux quad look like a Mac with MacBuntu and Docky and loads of Compiz tweaks and now me W7 looks like Ubuntu 10.10: http://www.webupd8.org/2011/02/make-windows-7-look-like-ubuntu-with.html#more

Hope it comes with Linux efficiency ;P

LoL

Re: Okay, I confez, I'm not a Linux Adapt.

Navigation in the Nautilus file manager is sometimes painfully slow. If one has Nautilus Elementary installed and on screen, one can though hit Ctrl-L or the little pencil icon in the tool bar and type a file location directly. As one is doing this the address area is offering the available paths, so when typing /var/lib/bo the pick list offers /var/lib/boinc-client. Also this Ctrl-L box is great to copy an address from a document or manual and paste it in and instant navigation takes place.

See http://www.khattam.info/howto-get-edit-path-p...lementary-2010-06-08.html

This way, if one has the an integrated terminal view expanded in Nautilus, it is also much quicker to do some command line activity in any particular location.

enjoy

edit: ''paste'' not ''past'' blushing

edit 2: Nautilus Elementary also works on Ubuntu 10.10 (Maverick)

Re: Okay, I confez, I'm not a Linux Adapt.

Good, that's the purpose of this quasi blog... to spread the word of Linux and take the sting out for those with threshold fear, and on that, the next next Ubuntu will be called Oneiric Ocelot

http://www.markshuttleworth.com/archives/646

Not a derivative of Onerous, but meaning Dreamy Cat.

Got DockBarX now running properly, very similar as with the Windows 7 Superbar. Small icons for running applications on the panel bar and on hover showing a thumbnail of the application screen. Visit http://www.techsupportalert.com/content/ubuntu-tips-and-tricks.htm

Re: Okay, I confez, I'm not a Linux Adapt.

Next up, easy file sharing with WebDav: http://www.linuxplanet.com/linuxplanet/tutorials/7314/1/

Got file sharing going using samba and other bits, inter-platform, but this is appealing too for maybe the future of the WCG Crunching charts: Come and fetch them :D

Re: Okay, I confez, I'm not a Linux Adapt.

Today got the FireFox 4 (Minefield) RC nightly build and wow, everythings still works the same it did... all extensions operational. This is the address to the ppa for Lucid and Maverick http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu Pick the main 4.0 bots and install. 3.6 and 4.0 both running concurrently to find the duhferences.

One continuing gripe: When searching a lost bookmark amongst the thousands, still no telling which bookmark folder it's in... maybe there's and extension for that :?

Re: Okay, I confez, I'm not a Linux Adapt.

I haven't figured out, why Ubuntu leaves older versions of kernels installed? They take 128 MB of disk space each, which can be lot for some users, when several versions of the kernel is installed. At least I haven't needed to go back to earlier versions during my few months of experience with Ubuntu.

I decided to remove these unused kernel packages as my GRUB menu was starting to need streamlining. And removing extra kernel packages seemed to be the easiest way to do this. Now I only have two latest versions of the kernel installed and the grub has fewer number of options available. This was then the first cleanup operation I have had to do to Ubuntu.
