  • git-flow cheatsheet – git-flow are a set of git extensions to provide high-level repository operations for Vincent Driessen's branching model. more This cheatsheet shows the basic usage and effect of git-flow operations
  • Voluntary – […] Our goal is to create open source software that promotes freedom of expression, privacy and the decentralization of power with an eye towards usability […] (Just for OSX at the moment)
  • A Visual Git Reference – This page gives brief, visual reference for the most common commands in git. Once you know a bit about how git works, this site may solidify your understanding.
  • SSH_VPN – Community Help Wiki – This page discusses using SSH to set up SSH-based point to point connections, which can then be used to create routes that create virtual private networks. Note that using SSH in this fashion is not the "best" way to create a permanent, stable VPN. Notably, SSH uses TCP, and TCP over TCP can provide abysmal performance under pathological conditions.
  • VPN over SSH – This how-to is intended to cover the details of how to establish a VPN (Virtual Private Network) over a SSH connection. Starting with open-ssh 4.3, you can now use a ssh connection to set up a VPN. This is technically termed "layer-3 IP-in-SSH tunnelling" and is not using ssh to port forward (ssh -L ) or create a dynamic "application level" forwarding (SOCKS) (ssh -D ). Rather a VPN is established using a SSH connection to create a virtual interface, tun0. Advantages : IMO, this technique is easier to set up then openvpn, especially if you are using a single client. Works with most Linux distributions without the need to install any additional software on the clients. The server only needs openssh-server. This protocol uses udp to transmit tunneled tcp connections resulting in a more stable connection compared with port forwarding (using ssh with the -L or -D options). Disadvantages : As of yet I do not know of a windows client which will use this protocol. If you are needing to set up a VPN with numerous clients I would use openvpn. Although there are several "how-to's" on the web, most of them assume you know something about networking and routing. This page attempts to explain some of the "missing details".

  • check_jvm – Nagios Exchange – JvmInspector is standalone tool + Nagios wrapper plugin (check_jvm) that dumps various properties from locally running JVMs. This information includes: * Heap & non-heap memory * Running threads * Loaded classes * Running java version, paths & arguments * On App servers only: Container server name & total active sessions (tested & supported app servers are tomcat5+ and jboss4+) JvmInspector doesn't need local or remote JMX network socket. It directly attaches to JVM's PerfData, so it MUST be started with the same USERid as the target JVM!
  • Raspberry Pi VPN Gateway – Netflix finally arrived in Germany, but guess what? It's library is heavily limited in comparision to the US one and if you like TV series as much as I do, you don't want to wait until they eventually release it year(s) later for us german users. Maybe you've heard recently of Anonabox — a small device with two ethernet ports that you can plug in front of your router and everything behind the device is routed through Tor (side note: turned out to be a scam and got pulled from Kickstarter in the end). However, it made me come up with an idea: Instead of having a Tor-box, I want a VPN-box that is connected to my PrivateInternetAccess VPN. If I'm in need of a VPN connection I just switch the WiFi network and I'm good to go. This way I can easily watch US content from Netflix as well as unblock location restricted content like YouTube, even with my iPhone or Xbox[…]
  • My Tmux Setup on unwiredcouch.com – I've been using tmux as my main terminal multiplexer for about 3 years now and have refined my configuration over time to fit my daily workflow. Which is usually a mix of writing code, chef recipes, remote login into different servers and various shell tasks. This is a flexible setup that doesn't concentrate too much on doing a specific thing or replacing an IDE inside of tmux.

  • microHOWTO: Configure Apache to use Kerberos authentication – To configure Apache to use Kerberos authentication Kerberos is an authentication protocol that supports the concept of Single Sign-On (SSO). Having authenticated once at the start of a session, users can access network services throughout a Kerberos realm without authenticating again. For this to work it is necessary to use network protocols that are Kerberos-aware. In the case of HTTP, support for Kerberos is usually provided using the SPNEGO authentication mechanism (Simple and Protected GSS-API Negotiation). This is also known as ‘integrated authentication’ or ‘negotiate authentication’. Apache does not itself support SPNEGO, but support can be added by means of the mod_auth_kerb authentication module.
  • How to create a bootable USB stick on OS X | Ubuntu – […] Note: this procedure requires that you create an .img file from the .iso file you download. It will also change the filesystem that is on the USB stick to make it bootable, so backup all data before continuing […]
  • thomastk/kunjumon – Kunjumon is a framework that can be used to create plugins for Nagios monitoring system, without writing any new code. The plugins thus created are robust, and, can monitor complex scenarios by querying data from multiple databases. While efforts to build such plugins would require considerable scripting work, using Kunjumon framework, a a plugin that pulls input data from databases can be implemented by defining it in XML format, and, there is no need to write any code to support it. The Kunjumon framework has been tested on all the Linux platforms, and against MySQL, Postgres, Oracle and Microsoft SQL Server. However, in general, it would work with any ODBC interface configured on the Nagios host to access a data repository.
