Open Data und Zwangsversteigerungen

nospam@example.com (Mo) — Fri, 17 Jun 2011 11:21:38 +0200

Eine große Anzahl an Amtsgerichten veröffentlichen die Termine für Zwangsversteigerungen von Immobilien auf www.zvg-portal.de. Ich hätte die Daten gerne im Rohformat, und habe eine diesbezügliche Anfrage gestellt - leider ohne Erfolg und mit kurioser Argumentation.

WebDAV, Windows 7 and Self-Signed Certificates Howto

nospam@example.com (Mo) — Wed, 06 Apr 2011 05:26:25 +0200

WebDAV is a nice protocol. Unfortunately, the Windows implementations of it are amongst the crappiest pieces of software ever written. I thought it was better on Windows 7, but it still sucks. Here's how you can make it work at least for read access with HTTPS and self-signed certficates.

Always up SSH SOCKS Proxy on Windows

nospam@example.com (Mo) — Tue, 29 Mar 2011 19:16:06 +0200

For additional security, I use SSH tunneling to one of my servers and dynamic port forwarding for some of my applications. This post explains how to use Putty to have a tunnel/SOCKS proxy that is created automatically on startup, and reconnects when disconnected, without any annoying windows open.

My Favorite Portable Virus Removal Tools

nospam@example.com (Mo) — Sun, 13 Mar 2011 15:18:07 +0100

I was just asked for my favorite free portable anti-virus solutions. In general, nowaways, you will most likely have to reinstall because most malware digs too deep into your system to be removed again. The first thing you need to do is THINK about the source of your infection. In 99% of all cases is YOUR fault if you get infected, and you will get infected AGAIN if you don't learn.
With that warning in mind, if you know what you did wrong, and if you still want to run anti-virus software, I recommend MWAV (mirror) and Spyware S&D. Boot a clean OS from CD, eg. Hiren.

Hacker Psychology I

nospam@example.com (Mo) — Sat, 12 Mar 2011 14:53:11 +0100

This is a very obvious stategy, mostly applied subconciously by those that know the trade. I've had the pleasure of seeing it work in a lot of open source projects. It is also among the strategies suggested in the excellent book Coders at Work.

Create an encrypted file system on Android with LUKS

nospam@example.com (Mo) — Wed, 09 Feb 2011 14:20:33 +0100

QUOTE:

LUKS is the standard for Linux hard disk encryption. By providing a standard on-disk-format, it not only facilitates compatibility among distributions, but also provides secure management of multiple user passwords.

Building off the work from other great sources, the Guardian Project hack team decided to take a crack at porting LUKS to Android recently, with the goal of creating a proof of concept build process that can be easily adapted to future projects.

Howto: Install TARPIT on Debian Stable (Lenny)

nospam@example.com (Mo) — Thu, 03 Feb 2011 14:29:22 +0100

QUOTE:

Add a TARPIT target to iptables, which captures and holds incoming TCP connections using no local per-connection resources. Connections are accepted, but immediately switched to the persist state (0 byte window), in which the remote side stops sending data and asks to continue every 60-240 seconds. Attempts to close the connection are ignored, forcing the remote side to time out the connection in 12-24 minutes.

Running an own microblogging server has several advantages over using Twitter directly. Many applications support Status.net as an open source implementation, and your tweets can conveniently be pushed to your Twitter account.
