I was wondering how to make my touchpad settings permanent in Ubuntu. I could find a few pointers on the net, like:
But sometimes it makes sense to look at your own system’s documentation:
% cd /usr/share/X11/xorg.conf.d
% head 50-synaptics.conf
# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# DO NOT EDIT THIS FILE, your distribution will likely overwrite
# it when updating. Copy (and rename) this file into
# /etc/X11/xorg.conf.d first.
# Additional options may be added in the form of
# Option "OptionName" "value"
#
Section "InputClass"
Which seems pretty obvious to me. I added
Last week, the Dutch public broadcaster (NOS) decided to “fix” their online teletext offering, there breaking [an old script I had laying around](/2008/july/15/teletext_nl_script/index.htm l). Their new web interface (displaying gifs) can be found here.
After @bdekruijff discovered their newly, hidden text feed, I decided to adapt the old script to this new situation. Thanks to this page I was able to (partially) reconstruct the feed. Most escape sequences are working, I’m still fiddling with finding Unicode chars for the “Contiguous Graphics Set”.

Thanks to the help of Marc Petit-Huguenin I have been able to create (and upload) debian packages (install fine on Ubuntu) for Pandoc2rfc and xml2rfc. For Pandoc2rfc I choose to add a little shell script that calls pandoc and xml2rfc for you. So creating an I-D is as simple as:
pandoc2rfc *.mkd # or a few other extensions
The shell script depends on transform.xsl to be installed in /usr/lib/pandoc2rfc/,
allthough this can be overridden with a flag. When pandoc2rfc is installed you don’t
have carry the supports scripts inside your I-D’s source repo. My pandoc2rfc I-D
source directory now only has: template.xml, abstract.pdc, back.pdc, middle.pdc and a
bib/ directory with references.
I like Vim, so I try to use it at many places. Like in my shell (set -o vi), and
when writing and coding.
After some Googling I found that Vim can also be used as a MANPAGER. But there is
one nagging issue. To quit viewing the manual page you have to type ‘:q’, which is
one keystroke more then when using less as your MANPAGER… Needless to say: this
is unacceptable.

In the standard library the DNS types have been renamed from RR_MX to MX which I
think is a good change. So I made the same change in Go DNS, but this time
I’m providing gofmt -r rewrite rules. They all have the form:
gofmt -r 'RR_A -> A' -w *.go
And then for all the types, so it’s quite a list.
Download the rewrite rules here and use
it like $SHELL rewrite.
I’m starting to get really happy about the Go DNS API, so invasive API changes are less and less likely.
We want to create a little program that prints out the MX records of domains, like so:
% mx miek.nl
miek.nl. 86400 IN MX 10 elektron.atoom.net.
Or
% mx microsoft.com
microsoft.com. 3600 IN MX 10 mail.messaging.microsoft.com.
We are using my Go DNS package.
First the normal header of a Go program, with a bunch of imports. We
need the dns package:
NSEC3 - A shadowy flight into the dangerous world of a record who does not exist.
Denial of Existence, a young loner on a crusade to champion the cause of the innocent, the helpless, the non-existent, in a world of records who operate above the law.
Inspired by NLnet Labs and PowerDNS, I figured I couldn’t stay behind, so here is how to add new RRs to Go DNS.
A small note before I delve into the details, I haven’t optimized Go DNS for adding new types, as this is a relative infrequent event. There are a few items that need to be added before Go DNS understands the new RR type.
RR interface;Lets take the new DANE (RFC6698) as an example. The record is called TLSA, and looks like:

This is an official announcement from SIDN also published here.
In the course of Sunday 28 October, an error occurred during the publication of a new ZSK (with key tag 20331). Because of the error, the new ZSK was not published in the DNS when it should have been. However, the software used by SIDN (OpenDNSSEC) continued to work on the basis that the ZSK had been published successfully.

Indeed a really nice font and fully open source. Using it now at 11pt. See:
I’m a huge fan of syntax highlighting in my editor Vim. One thing I started to
miss was that user defined type miss out on the highlighting, because Vim does
not know about them. Wouldn’t it be cool to have some sort of automatic support that
detect your types and adds them to the correct highlighting group? I call
this “dynamic syntax highlighting”.
As a proof-of-concept I took the tagbar
plugin, and modified it a little to take
advantage of the language detection (specifically the types). The modified code
can be found in my fork on github.
When editing zone files with vim I always get annoyed by the fact that the syntax highlighting did not understand newer types ’n stuff. I never did anything about until now.
Download this vim syntax file and drop it
in ~/.vim/syntax. It adds newer (DNSSEC) types and base64 highlighting. Base64 only works
when there are no embedded spaces (patch welcome to fix that btw!)

If you do DNS for too long everything looks like 53.
In this “trace” I’m showing the logging of fksd when I add a
zone, try to list it as a non-existent user miekg (which fails), add the user
miekg and list it again. User are identified by the key in the TSIG record, their
password is the shared secret.
The “config files” from nsupdate can be found in the github repo
of fksd.
The nsupdate commands are preceded with a %, extra comments are preceded with #:
I’m writing a nameserver called fksd (Funkensturm daemon), which is
currently in a prototype stage (but the code is available at
github).
In this server I’m pursuing some interesting directions in nameserver development, such as the dynamic configuration as provided by BIND10.
BIND10 uses http(s), but I think using DNS packets is more in line with a nameserver, so I opted for that route.
With fksd you can use packets (which will be TSIG signed in the
future tomorrow) to configure the server. The only configuration possible at the
moment is adding a zone. Such a packet needs to have a TXT record like
the following in its AUTHORITY SECTION:

I’ve created a small wrapper for libunbound for use in Go.

import (
"dns"
"fmt"
"os"
"unbound"
)
func main() {
u := unbound.New()
defer u.Destroy()
if err := u.ResolvConf("/etc/resolv.conf"); err != nil {
fmt.Printf("error %s\n", err.Error())
os.Exit(1)
}
if err := u.Hosts("/etc/hosts"); err != nil {
fmt.Printf("error %s\n", err.Error())
os.Exit(1)
}
r, err := u.Resolve("www.nlnetlabs.nl.", dns.TypeA, dns.ClassINET)
if err != nil {
fmt.Printf("error %s\n", err.Error())
os.Exit(1)
}
fmt.Printf("%+v\n", r)
