Self executing watchr script

2010-01-11T09:53:00.004Z

watchr monitors a directory tree, and triggers a user defined action whenever an observed file is modified.

Example test.watchr:

watch("lib/(.*)") { system "rake" }
Signal.trap("INT") { run_tests }

This script executes rake test whenever a file in lib/ changes.
To start watchr run watchr test.watchr on command line.

In order to execute this script itself insert a shebang and do chmod a+x test.watchr:

#!/usr/bin/env watchr
watch("lib/(.*)") { system "rake" }
Signal.trap("INT") { run_tests }

Now you execute that script with ./test.watchr.

Nice, uh? :)

autotest notifications with Gnome's notify-send

2008-11-11T12:14:00.007Z

Create the following files ($HOME/.autotest and $HOME/bin/notify_redgreen). Run autotest in your applications folder (e.g. rails or merb).

$HOME/.autotest:

module OSD
PATH = ENV['HOME'] + "/bin/notify_redgreen"

def self.notify(color, msg)
  system "#{PATH} #{color} #{msg}"
end

Autotest.add_hook :red do |at|
  notify(:red, at.results[/\d+ tests.*$/])
end

Autotest.add_hook :green do |at|
  notify(:green, at.results[/\d+ tests.*$/])
end
end

$HOME/bin/notify_redgreen:

#!/bin/sh

Terratec Hybrid Cinergy XS auf gentoo

2007-12-27T10:44:00.000Z

Geschafft! Der DVB-T Stick funktioniert nun auf unter gentoo.

Die Erleuchtung kam hierher:

Einfach die expirementellen Treiber nutzen!

Warum ich das hier schreibe? Damit google es besser findet - das nächste Mal ;)

man 1 id3

2005-12-01T16:18:00.000Z

Just did

$ man id3

on Debian:

BUGS

The ID3 format has some shortcomings. There is a 1 in 16777216 chance of your mp3 having a certain bit-pattern, causing id3 to write over the last
128 bytes of your mp3 upon tag creation. If you add a track number to an ID3 v1.0 tag, the last two characters of the comment string will be trunâ

trunâ? Truncated? ;-P

Bleeding edge: lighttpd-1.4.8 and eaccelerator-0.9.4-rc1

2005-11-24T00:01:00.000Z

There is a new version of lighttpd (1.4.8) and eaccelerator (0.9.4-rc1) available.
Both are running without problems up to now (about 5 hours ;).

Remember:

"If you are on a bleeding edge, you will bleed."

$ HEAD localhost | grep Server

lighttpd with daemontools on Debian

2005-11-23T23:43:00.000Z

I love lighty, daemontools and Debian.
There are 3 step to combine them (assuming you have lighttpd already installed).

Step 1

Install daemontools.

$ apt-get install daemontools-installer
$ get-daemontools
$ build-daemontools

(I am using /service-style.)

Step 2

Create run script.

$ mkdir /service/lighttpd
$ cat <<EOF > /service/lighttpd/run
#!/bin/sh
exec /usr/sbin/lighttpd -f /etc/lighttpd/lighttpd.conf -D
EOF

(lighttpd will be started automagically)

Step 3

Remove lighttpd from init.d

$ update-rc.d -f lighttpd remove

Now, use svstat and svc as usual :)

Thats all folks!

RAW: The enterprise evaluation of Rails vs Java

2005-11-23T15:00:00.000Z

Evidence I:
Riding Rails writes about Rick Bradley's evaluation document which deals with "picking Rails over Java".

If don't know what I'm talking about, read RAW: Introduction.

RAW: Introduction

2005-11-23T14:45:00.000Z

What?

In this section I'll gather posts from people who are moving from Java to Ruby (especially Ruby on Rails.

Why?

I'll try to convince my boss to use Ruby and drop Java in most cases.

RAW?

RAW ("Rubylution at work") is the code name for my mission.

Rubylution?

This name fits well, I think. Flori (guy who dislike Java too ;) has a blog named "Rubylution".

lighttpd writev problem and solution

2005-11-18T10:07:00.004Z

Problem

I am hosting Pflegewiki using lighttpd (version 1.4.7) + FastCGI-PHP.
Two days ago I got emails from users which had problems uploading files (503 - Service Not Available). I could reproduce this problem only trying to upload large files (> ~100Kb).

The logfile said:

2005-11-18 10:27:41: (network_writev.c.276) write failed: Bad address 16
2005-11-18 10:27:41: (mod_fastcgi.c.2751) write failed: Bad address 14

Workaround

As a temporary workaround I switched network backend from "writev" to "linux-sendfile":

server.network-backend = "linux-sendfile"
#server.network-backend = "writev"

It works and should peform better than "writev", Jan said.

Solution

I was about to submit a bug report so I searched for "writev" here and found a patch (changeset #829) which solves this issue. After patching and switching back to "writev" everything worked fine.

However, I use "linux-sendfile" anyway, now.

Update: blogger.com sucks. I had to delete tons of entries... Sorry.

Borussia-Duell

2005-11-01T09:29:00.000Z

Es ist fast schon eine kleine Tradition, einmal im Jahr den Feind BVB beim Heimspiel gegen die "echte Borussia" zu bestaunen.

Eines vorweg: Das Spiel war nicht sonderlich gut und das nicht nur weil Gladbach 2:1
verloren hat (und somit für ca. 9500 mitgereisten Anhänger der Abend gelaufen war - mehr hier und hier) war.

Wie auch immer, hier ein paar Schnappschüsse.

Oh, fast vergessen: Leider hat auch der "Meister der Herzen" seine erste Saisonniederlage beim HSV erleiden müssen :(

ServerSide TiddlyWiki using WebDAV

2005-09-09T13:51:00.000Z

Bingo, I know... :)

With the SaveChangesToDAV-Plugin you can manage your TiddlyWiki online using WebDAV.
All you need is YATWA and WebDAV webserver e.g. apache.

It's implemented with XMLHttpRequest (Bingo bonus) and supports PUT and GET methods (so no locking, versioning etc.)

Expect bugs - have fun.

XSS in "Code Snippets" [Updated]

2005-04-09T09:21:00.000Z

Update:
The "XSS tag exploit" shown below will fail because the application doesn't allow single quotes and slashes! Anyway, Peter will fix the XSS issues ASAP...

Outdated:
Peter Cooper's nice "Code Snippets" (rails driven with tag support) is vulnerable to XSS:

(Snipped from my email to Peter)

1. Tags
 * http://www.bigbold.com/snippets/tags/ruby<body onload="alert('XSS')">
 -> tags should be escaped

2. Create user (http://www.bigbold.com/snippets/login/create)
 * Every input field is vulnerable to XSS:
   <body onload="alert('XSS')">
 -> input field should be escaped
 * The URL field accepts "javascript:" URLs: (NOT TESTED)
   javascript:alert('XSS')
 -> only allow %r{(f|h)ttps?://} (?)

I hope Peter will fix these issues soon :)
