  • Regular Expressions – Regular expressions ("regexes") are supercharged Find/Replace string operations. Regular expressions are used when editing text in a text editor, to: check whether the text contains a certain pattern find those pattern matches, if there are any pull information (i.e. substrings) out of the text make modifications to the text. As well as text editors, almost every high-level programming language includes support for regular expressions. In this context "the text" is just a string variable, but the operations available are the same. Some programming languages (Perl, JavaScript) even provide dedicated syntax for regular expression operations.
  • MySQL active-passive cluster | Your IT goes Linux – We will use the iSCSI Lun defined in our iSCSI cluster as a shared storage and we will run MySQL in active-passive (fail-over) mode using Pacemaker and Corosync cluster engine. The cluster will have to connect to the iSCSI target, mount the iSCSI partition on one node and start a MySQL service which has all its data on this partition.
  • Perl – […] Perl has horrors, but it also has some great redeeming features. In this respect it is like every other programming language ever created. This document is intended to be informative, not evangelical. It is aimed at people who, like me: dislike the official Perl documentation at for being intensely technical and giving far too much space to very unusual edge cases learn new programming languages most quickly by "axiom and example" wish Larry Wall would get to the point already know how to program in general terms don't care about Perl beyond what's necessary to get the job done. This document is intended to be as short as possible, but no shorter[…]
  • Linux Performance – This page links to various Linux performance material I've created, including the tools maps on the right, which show: Linux observability tools, Linux benchmarking tools, Linux tuning tools, and Linux observability sar. For more diagrams, see my slide decks below.
  • AIXchange: Useful Storage Links – Here's an assortment of really good storage-related articles — the majority of which are found on IBM developerWorks — that are worth your time. While some of them are a few years old, they still provide relevant information.

  • Samba e Active Directory .:. – Unire una macchina Linux (*BSD, Solaris, …) a un dominio (Active Directory) Windows talvolta è comodo, talvolta è utile, talvolta è necessario. Per ottenere questo risultato si usa Samba.
  • Squid e autenticazione su Active Directory .:. – È giunto il momento di rifare il proxy aziendale – ovviamente Squid – e con l'occasione cambio il metodo di autenticazione appoggiandomi al dominio: una password in meno per gli utenti e controllo più centralizzato. Le condizioni al contorno sono sempre quelle: Debian come guest su VMware ESX così aumentiamo la percentuale di virtualizzazione con tutti i pro (ma anche i contro).

  • Soup To Nuts – Repository of Open Source Articles and Example Code – This site is a collection of scripts, hints, articles, and programs.
    Performance Monitoring on Linux, Postfix 2nd Instance for Sender-based Routing: Multiple Gmail and Comcast Accounts, Linux Quota Tutorial , SQLite Tutorial, over 200 Linux tips and tricks, Virtual Filesystem: Building a Linux Filesystem from an Ordinary File, MySQL Tips and Tricks , MSSQL 2005 Tips
  • Dunigan’s Network Peformance Links – list of tools for network measurement and monitoring, tcp performance, etc
  • AIX A-Z: Learning AIX’s spooler back-end programs – Summary:  While most IBM® AIX® administrators know how to set up print queues and manage printing through the System Management Interface Tool (SMIT) or the general print commands, there's more to printing on the UNIX® system. If you want to learn more than just how to set up or manage virtual printers on AIX, this article is for you. Most successful AIX and UNIX administrators thrive on learning more about the system they administer. Printing is only one facet of their system, but it's an important one to know.
