Naming Schemes – A good naming scheme is scalable, unique, and easy to remember. The purpose of these naming schemes is to name networked servers, wireless access points or client computers, but it can also be used to name projects, products, variables, streets, pets, kids, or any other project where unique names and rememberable names are required.
SSD Cloud Hosting & VPS – MNX.io – Here at MNX, we’ve been busy setting up a brand new data center for our cloud hosted services. We started off as a consulting company providing managed Linux services, which means we have been exposed to a ton of different customer environments and an equal number of schemes for naming equipment…not all of them good. It’s a problem that goes back as far as computers have existed, and everyone has their own opinion on the “best” way to name hosts. Most methods start out fine at the beginning, but quickly become unwieldy as infrastructure expands and adapts over time.
Trello – Organize anything, together. Trello is a collaboration tool that organizes your projects into boards. In one glance, know what's being worked on, who's working on what, and where something is in a process.

Bash: parsing arguments with ‘getopts’ | rsalveti’s random thoughts – Today I was writing some scripts, and in every script I wanted something to handle all input arguments, in a good way, so I could pass my arguments in any order and my program would know about it. I used ‘getopts’ before, but this time I decided to write some stuff here about it.
dayid’s screen and tmux cheat sheet – A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

LDAP org chart | bitcube.co.uk – For centralised authentication and authorisation, LDAP is the de-facto standard. Whether in its pure form on Unix or in Active Directory guise on Windows, everyone uses it. What many people don't realise is that you can store all sorts of useful (and not so useful) information in LDAP. One field which can be useful is the "manager" attribute. One of our customers use that and so we've written a small script to graph it using the excellent Graphviz tool. It will probably need customising for specific cases, however we hope that people find it useful nonetheless. If you want to alter the output, do have a look at the record format documentation.
Puppet errors explained | bitcube.co.uk – Puppet is a wonderful system automation tool, however the learning curve can be a little steep. We've collected some of the errors messages and "strange" behaviour you may come across together with explanations to help overcome these hurdles and boost adoption of this fabulous tool. If you have any useful errors and explanations, please do send them in and we'll update this article.
DNS Load Balancing and Using Multiple Load Balancers in the Cloud – [...] Load balancing in general is a complicated process, but there's some secret sauce in managing DNS along with multiple load balancers in the cloud. It requires that you draw from a few different sets of networking and “cloudy” concepts. In this second article in my best practices series (my first post covered how to use credentials within RightScale for storing sensitive or frequently used values), I'll explain how to set up load balancers to build a fault-tolerant, highly available web application in the cloud. Here's what you’ll need: Multiple A records for a host name in the DNS service of your choice Multiple load balancers to protect against failure [...]
gdnsd – gdnsd is an Authoritative-only DNS server which does geographic (or other sorts of) balancing, redirection, weighting, and service-state-conscious failover at the DNS layer. gdnsd is written in C using libev and pthreads with a focus on high performance, low latency service. It does not offer any form of caching or recursive service, and notably does not support DNSSEC. There's a strong focus on making the code efficient, lean, and resilient. The code has a decent regression testsuite with full branch coverage on the core packet parsing and generation code, and some scripted QA tools for e.g. valgrind validation, clang-analyzer, etc. The geographically-aware features also support the emerging EDNS Client Subnet draft for receiving more-precise network location information from intermediate shared caches.
kandanapp/kandan · GitHub – What is Kandan? Kandan is a private chat service for your company or team. You can invite colleagues to share ideas and files in a persistent group chat room or rooms. Unlike HipChat or other alternatives, Kandan is completely Open Source and can be hosted internally or externally by your organization or by a third party.
GitSvnCrashCourse – Git SCM Wiki – Welcome to the Git crash course for SVN users! This introduces you to Git based on your current Subversion knowledge. If you want to migrate your company from SVN to Git, see the SVN migration page. If you want a list of common commands, see the Git Cheat Sheet (or the git-svn guide if you are using Git as a subversion client. Many non-SVN-specific guides are also available. This crash course is based on Pasky's unmaintained version.
Use vim at its best to edit your Puppet manifests – Linuxaria – Using this repository you’ll enable the following plugins: pathogen Makes it super easy to install plugins and runtime files in their own private directories. snipmate.vim snipMate.vim aims to be an unobtrusive, concise vim script that implements some of TextMate’s snippets features in Vim. syntastic Syntastic is a syntax checking plugin that runs files through external syntax checkers and displays any resulting errors to the user. This can be done on demand, or automatically as files are saved. If syntax errors are detected, the user is notified and is happy because they didn’t have to compile their code or execute their script to find them. tabular Sometimes, it’s useful to line up text. Naturally, it’s nicer to have the computer do this for you, since aligning things by hand quickly becomes unpleasant. vim-puppet Make vim more Puppet friendly! vim-fugitive Provides an amazingly deep Git integration for vim.
