  • blblack/gdnsd – gdnsd is an Authoritative-only DNS server. The initial g stands for Geographic, as gdnsd offers a plugin system for geographic (or other sorts of) balancing, redirection, and service-state-conscious failover. The plugin system can also do things like weighted address/cname records. If you don't care about these features you can ignore them :).
  • How to Create and Apply Patches in GIT using diff and apply Command – Creating a patch in GIT is a great way to share changes that you are not yet ready to push to a public branch of a project.
  • Your own Dynamic DNS in 3 steps | The Nexus – This is a "niche" post: it will really only appeal to you if you have access to your own — or a friend's — name servers and want to use your own domain to track your dynamic IP addresses, such as your home router's. You will still have to buy your own domain, cheap if you go to internet.bs or namecheap.com. I hear that the latter even provide their own dynamic DNS service although I cannot tell you anything about its quality/flexibility. So, why this post? It's for you, my friends, budding entrepreneurs who wish to bootstrap your business and know that every cent counts. Maybe you feel that you could host your product's web site on a home computer. Maybe you need more control over what happens on that server. Or maybe you want to be able to log on to your development machine from anywhere in the world. Whatever your reasons, you're still here. So let's get started.
  • Apache – Prefork or Worker | Code Bucket – Apache is the most common and famous webserver. Everyone knows about apache and most of us also have hands on experience with apache. But few of us know that apcahe2 comes with 2 multi processing modules(MPMs): 1. Prefork 2. Worker
  • Ottimizzazione di Apache, dall’analisi ai parametri – […] I recenti sviluppi nel campo della virtualizzazione hanno accelerato la moltiplicazione di ambienti virtuali vps a basso costo, molto convenienti ma a volte carenti dal punto di vista delle risorse di sistema. Molto spesso questi ambienti vengono utilizzati a scopo di testing o come ambienti di produzione all'interno dei quali viene implementato l'utilizzo di un web server. Apache, come ben sappiamo ,e uno dei web server piu diffusi e nella maggioranza dei casi rappresenta la scelta di default su un grandissimo numero di installazioni […]

  • Bucky — Performance Measurement of Your App’s Actual Users – Bucky is a client and server for sending performance data from the client into statsd+graphite, OpenTSDB, or any other stats aggregator of your choice. It can automatically measure how long your pages take to load, how long AJAX requests take and how long various functions take to run. Most importantly, it's taking the measurements on actual page loads, so the data has the potential to be much more valuable than in vitro measurements. If you already use statsd or OpenTSDB, you can get started in just a few minutes. If you're not collecting stats, you should start! What gets measured gets managed.
  • Linux on 4 KB sector disks: Practical advice – Advanced Format disks use 4,096-byte sectors rather than the more common 512-byte sectors. This change is masked by firmware that breaks the 4,096-byte physical sectors into 512-byte logical sectors for the benefit of the operating system, but the use of larger physical sectors has implications for disk layout and system performance. This article examines these implications, including benchmark tests illustrating the likely real-world effects on some common Linux file systems. As Advanced Format disks have become the norm, understanding how to cope with these disks is a vital skill for anyone who wants to avoid serious performance penalties associated with suboptimal configuration.
  • WPScan by the WPScan Team – WPScan is a black box WordPress vulnerability scanner.
  • SiteSucker for OS X – SiteSucker is a Macintosh application that automatically downloads Web sites from the Internet.

  • Observium – Observium is an autodiscovering SNMP based network monitoring platform written in PHP which includes support for a wide range of network hardware and operating systems including Cisco, Windows, Linux, HP, Dell, FreeBSD, Juniper, Brocade, Netscaler, NetApp and many more. Observium has grown out of a lack of network monitoring platforms which are both simple to manage and pleasant to use. It is intended to provide a navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, using as much auto-discovery as possible with little or no manual intervention, and having a very intuitive interface. Observium is not intended to replace an up/down alerting system like Icinga or Nagios, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.

  • Using KVM virtualization – Kernel Virtual Machine (KVM) virtualization has largely replaced Xen as the default open source mechanism for creating and supporting virtual machines (VMs) on most Linux systems. Though the motivation for this change is primarily build and support related rather than technical, the reality is that many enterprise IT groups that are interested in virtualization will need to learn the administrative command-and-control tools that KVM uses. Similarly, IT shops with an existing investment in Xen virtualization that are moving to KVM will probably want to convert existing VMs to the formats that KVM supports whenever possible, rather than having to re-create them.

  • Ratuus – RATUUS is an easy to use, web based system for administration of POSTFIX virtual domains and users. Sounds good, but what does it really mean? Postfix mail server is able to work with non-system users, users which are not known to the operating system. This functionality is very useful since it gives you possibility to use one mail server for multiple domains without worrying that usernames will overlap. Like this you can have address [email protected] and also [email protected] and they can all point to different mailboxes. These kind of users are usually stored in some kind of a database, with MySQL database being most commonly used. And this is where RATUUS comes into play – it provides user friendly interface for managing these virtual users and domains. With RATUUS you can easily create, modify and delete domains, users and aliases and all your actions are immediately reflected to Postfix configuration. RATUUS is using the same database layout as famous PostfixAdmin so migration
