Finally, NetBSD Boots in KVM!

2010-08-29T18:44:22Z

Compared to OpenBSD and FreeBSD the NetBSD install was hard, really hard. It wasn't until I stumbled across this that I managed to convince myself to try it again.

The trick seems to be to ignore as much as you can from other Internet tips. NetBSD runs fine in KVM, so if someone says you need to run it in Qemu mode - don't believe the hype. OK, in virt-manager there is no preset defaults for NetBSD, so I went with a generic OS and tried starting the install from there. The kernel hangs before it probes USB, or it segfaults.

What I did was to stop the guest, and in the details view I disabled ACPI and selected the pcnet NIC instead of the default ne2k-pci. Running the default options in the NetBSD 5.0.2 installer, and the bootloader after install, works fine.

Good Luck!

Announcing Minix editline 1.14.0

2010-08-12T16:17:09Z

It is with great pleasure I announce the next release of the editline library by Simmule Turner and Rich Salz! This is a popular library, it exists in several forked versions. This release marks the end of a huge effort where archaeological methods have been applied to recover fixes and improvements developed independently over several decades by the following projects: Heimdal, Festival speech-tools, Debian, and Mr. Steve Tell.

Noteworthy changes and additions:

The symbols rl_complete() and rl_list_possib() are no longer possible to overload as function pointers. Instead the FSF libreadline rl_set_complete_func() and rl_set_list_possib_func() API has been added for implementing custom completion handlers.
8-bit handling now work correctly on non-utf8 terminals, including meta characters and key bindings. This is actually a revert of an old broken Debian patch.
The functions el_bind_key() and el_bind_key_in_metamap() have been added thanks to the efforts of Festival speech-tools hacker Mr. Alan W. Black.
Support for capitalizing words (M-c), also from Mr. Alan W Black.
Improved FSF libreadline compatibility and signal safety fixes by Mr. Steve Tell.
The HUGE code cleanups are mostly courtesy of the Heimdal Project,.
Several more APIs for increased compatibility with FSF libreadline have also been added. See the file include/editline.h for details.

Minix editline moves to GIT

2010-07-19T00:40:00Z

A small heads-up, I've migrated the Minix editline project from Bazaar to GIT. The new URL for keeping tabs on your favourite free readline() clone is:

http://git.vmlinux.org/editline.git/

I'm currently working on fixing up the tree and doing some house cleaning - including making more stuff configurable - before releasing a 1.14.0 later on.

One such item is the integration of libtool with our autoconf friends. This should make it lot more portable (again) and also help smooth a merge with other sources for this library. More on that as well, later, hopefully.

Git Quickie

2010-07-13T18:45:07Z

This is a document I intend to maintain for my own purposes. It serves like a quick reminder to the steps I need to take when creating and working with git repositories.

First setup a bare repository on the server.

$ git --bare init projectX.git
Initialized empty Git repository in /pub/git/projectX.git/

Set one-liner description, visible in gitweb.

$ echo "Secret Project-X use ROT13 to decode all source files" >projectX.git/description

Setup a post-update hook so that the server repo is update automatically when you push to it.

$ cp ~/public_html/programming/post-update projectX.git/hooks/

Change how the "Owner" field in gitweb is displayed to include an obfuscated email address.
$ vi projectX.git/config

[gitweb]
        owner = "Joachim Nilsson <troglobit()vmlinux!org>"

These steps have become so common to me that I've setup a script to create server side git repositories.

You can now push to the server, after having setup remote location on the client.

$ git remote add origin ssh://login@example.com/pub/git/projextX.git
$ git push origin master
$ git push --tags

Simple Guide to Converting from Bazaar to GIT

2010-07-12T23:56:58Z

You need git, and bazaar obviously. Also install bzr-fastimport, it contains the export plugin as well. The rest is a rip off from the folloing URL: http://fthieme.net/en/drupal6/node/77.

git init project.git
cd project.git
bzr fast-export --export-marks=.git/bzr.mark ~/project.bzr | git fast-import --export-marks=.git/git.mark

That worked for me. The output will likely be something like this:

01:41:19 Calculating the revisions to include ...
01:41:19 Starting export of 33 revisions ...
01:41:20 Exported 33 revisions in 0:00:01

Syntax Highlighting in less

2010-05-09T17:53:00Z

Yes, it's certainly possible and source code becomes so much easier to read. Try it out by downloading my .lessfilter, save it as ~/.lessfilter in your $HOME.

Then try it out on a C source file: less -R myfile.c, soon you will probably add a line alias less="less -R" to your ~/.bash_aliases file. :-)

HowTo Move Window Controls Back to the Right Side

2010-05-01T14:46:53Z

When you've installed Ubuntu 10.04 you might want to have the window controls back to the right side, where you're used to having them. Use the following simple command:

   gconftool-2 --set /apps/metacity/general/button_layout --type string "menu:minimize,maximize,close"

Best. Programming. Font. Ever.

2010-04-26T20:44:17Z

This is not only a reminder to myself, it is appraisal to the probably best programming font ever: Inconsolata. Thank you Mr Raph Levien!

On the previous laptop I used ProFont quite extensively, but its screen was only 1280x800, on the new laptop I have 1680x1050 and ProFont just got too small for my aging eyes.

HowTo Hide Window Titlebar on Maximized Windows

2010-04-17T22:11:47Z

This is a "reblog" of another excellent post.

Open the Compiz config panel: either using the terminal "ccsm" or from the Gnome menu: System→Preferences→CompizConfig Settings Manager
Go to "Window Decorations", in Category Effects
On the penultimate line; "Decoration Windows", the default is "any", meaning all windows have a titlebar
Replace "any" with "!state=maxvert"
