  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

  • Booting once-only – GNU GRUB Manual 0.97 – You can teach GRUB to boot an entry only at next boot time. Suppose that your have an old kernel old_kernel and a new kernel new_kernel. You know that old_kernel can boot your system correctly, and you want to test new_kernel.<br />
    To ensure that your system will go back to the old kernel even if the new kernel fails (e.g. it panics), you can specify that GRUB should try the new kernel only once and boot the old kernel after that.<br />

  • ottimizzazioni (quasi) estreme – In fondo, perché far ricomprimere ad Apache lo stesso file centomila volte al giorno, se questo non cambia praticamente mai? Non sarebbe possibile comprimerlo “a priori” e poi istruire il server a fornire la giusta versione a seconda che il browser dell’utente supporti o meno il formato gzip? A quanto pare la risposta è si
  • Trouble-Maker – Being a system administrator is full of interesting challenges. We like this. However, some of these challenges can be problematic, if they cause service interrupts on production systems. Most system administrators have run into the situation where something is wrong, the server is down, and we don't know what is going on. This project attempts to help.<br />
    <br />
    There are a lot of tools out there to make the system administrator's life easier. However, no tool is a replacement for properly understanding the system and experience in troubleshooting unknown situations. This is where Trouble-Maker comes in. Unlike other projects, we do not attempt to solve problems — we cause them.

  • Puppet is system administration – Automated. – Puppet is a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration.
    By saving you countless hours of frustration, monotony, and/or reinventing the wheel, Puppet can change your life. Here are some key points about Puppet:
    Puppet lets you perform normal administrative tasks (such as adding users, installing packages, and updating server configurations) on any number of systems, even if those systems are running completely different operating systems. Through the use of providers, Puppet takes a generic instruction from you (such as ensuring MySQL is installed) and performs the task the "right way" for each system.
    Whether you have a small, heterogeneous network of user workstations or a cluster of rack-mounted number-crunchers, Puppet can help reduce your overhead and get the everyday management of your network under control so you can concentrate on the real problems.

  • Hive – Hadoop Wiki – Hive is a data warehouse infrastructure built on top of Hadoop. It provides tools to enable easy data ETL, a mechanism to put structures on the data, and the capability to querying and analysis of large data sets stored in Hadoop files. Hive defines a simple SQL-like query language, called QL, that enables users familiar with SQL to query the data. At the same time, this language also allows programmers who are familiar with the MapReduce fromwork to be able to plug in their custom mappers and reducers to perform more sophisticated analysis that may not be supported by the built-in capabilities of the language.
