John Macfarlane released a new version of Pandoc that has a lot of new enhancements. A lot of things have changed in the Markdown input types and it’s now compatible with PHP Markdown. This is very nice, because a lot of implementations use the extensions defined by PHP Markdown.
I downloaded the dmg file to install it on my MacBook Pro and it works like a charm.
So, I decided to install it on my new CentOS 6 server to build documents there. Well, I was in for a nice surprise.
Today a colleague asked me to sync some files to a server that is not
listening on SSH port 22.
I normally create a configuration entry in my ~/.ssh/config file, like
Host tosync
Hostname syncer.example.com
Port 1234
User syncuser
and then command
rsync -va --progress --inplace . tosync:
But this time I didn’t want to create the entry in my SSH configuration,
because I need this trick in a script. So I started to read the rsync
manpage and after some experimenting I found
After upgrading my MySQL database server from version 5.0.95 to 5.1.61 I suddenly got these errors in the backup logging.
mysqldump: Couldn't execute 'SELECT /*!40001 SQL_NO_CACHE */ * FROM `EVENTS`': Cannot proceed because system tables used by Event Scheduler were found damaged at server start (1577) dbdump gave errorcode 2 for database 'information_schema' 2012-08-09 09:07:53 -> Finished MySQL backup on host 'xxx.tonkersten.com'
Hmm, no idea what has happened. I hope I didn’t do something stupid.
Today the classic, and old, Common Desktop Environment (a.k.a. CDE) was released into the Open Source world.
You can get the very alpha version at SourceForge.
I haven’t been able to get a running version by now, but I keep trying.
Good job, guys.
Working with git a lot I decided I needed some git status in my
prompt.
I searched the web and some solutions where almost what I wanted and this one by Sebastian Celis came very close.
But it didn’t work with my version of zsh, because that didn’t seem to
understand the =~ operator.
I also think Sebastian makes things over complicated and so I changed some things aroud.
This is what I came up with:
When installing a minimal CentOS 6 system, minimal really, really means minimal. After a reboot the network interfaces do not start, so network connectivity is non existing.
Looking into that I noticed that the file
/etc/sysconfig/network-scripts/ifcfg-eth0 contained
DEVICE=eth0 HWADDR=11:22:33:44:55:66 NM_CONTROLLED=yes ONBOOT=no BOOTPROTO=dhcp TYPE=Ethernet USERCTL=no PEERDNS=yes IPV6INIT=no
The lines that mess things up are NM_CONTROLLED=yes meaning the
interfaces are managed with NetworkManager, which isn’t actually
installed as part of a minimal install. You want a minimal install, you
get a minimal install. And ONBOOT=no, meaning do not start the interface on boot.
How stupid is that!
It often happens that I get into a situation where I need to know key
codes of pressed keys. On my Mac that’s simple. Just use the Key Codes
by Many Tricks.
But on Linux I constantly was trying to find out which key produced what.
So I ended up writing a program for that. I started of in the shell, but that ended up being rather tricky and unnecessary complicated. So I redid the whole thing in C.
Today I’ve posted a new version of the header program.
Nothing really fancy happened, just added support for zonefiles, in
this case the Bind ones.
It’s available at the usual places.
I’m creating a Puppet Starter Kit with some standard manifests
included and a complete set of documentation. All documentation should
be written in Markdown
and will be served by Markdoc. But I want to
generate all Markdown files from the Puppet manifests, so I only need to
document the manifest file. Generating the Markdown is not that
difficult, except that I kept ending up with empty lines at the top of
the manifest code and I wanted to get rid of those. Of course this
should be done with sed, because the whole generation process is
written in bash. When playing around with sed I found ~ sed
`/./,$!d' filename ~ which, I think, is genius in it’s simplicity.
After you find something, do not remove. Life in UNIX and Linux is nice!
I have a eeePC 900 (the 9” version) running Arch Linux for some time now. I didn’t update it for a while, so, today being a rainy Sunday, I decided it was time to do it.
So, I typed:
pacman -Syu
and waited for about half an hour.
And look what I got
Linux eeetje 3.0-ARCH
Everything is running nice and smooth, so I’m very happy.
Can’t wait to get my hands on Linux 3.11 for Workgroups ;-)
Some users insist on using bash. This is a good shell, but not as good
as zsh. But, I do want them to be able to use the per directory
umask as well as all the zsh users.
So I started digging, as the bash shell does not support a chpwd
hook.
This is what I came up with:
chpwd()
{ # Set the initial umask
case "${PWD}/"
in
/etc/puppet/*)
um=$(umask)
umask 007
;;
*)
[[ x"${um}" != x"" ]] && umask ${um}
;;
esac
}
function cd()
{
builtin cd "${@}"
chpwd
}
