Mini Cooper automobiles have the option to be fully configured to a geek’s liking. One feature they offer is the Mini Connected add-on. This lets you connect your smartphone via Bluetooth or USB to access the media and other features. In this tutorial, I will outline how to pair a Bluetooth phone to your Mini Connected system and also enable the Office feature.
In order to use Apache Maven for dependency resolution and automatic resolution of transitive dependencies for software projects on a Windows machine, it is necessary to set the proper Windows Environment Variables. This setup is necessary on all modern versions of Windows, and the steps to do so are also similar for all versions.
Understanding PHP’s numerous built-in functions for manipulating strings is essential if you ever want to be efficient with the language.
ZFS supports a type of RAID-5 redundancy called raidz. This redundancy works at the ZFS pool level and affects all created filesystems in that pool. According to the Sun docs, raidz offers “better distribution of parity [than RAID-5] and eliminates the ‘RAID-5 write hole’ (in which data and parity become inconsistent after a power loss).” Creating RAID volumes in most volume managers (like VeritasVM) requires learning a new language describing the various components involved. ZFS only requires one command.
Have you ever run out of disk space on your production server? Do you cringe at the downtime required to bring filesystems offline, backup, create bigger filesystems, and restore, all the while typing with crossed fingers? Do you dread deciding the disk layout for your new server? You do not need to panic! ZFS has you covered. In one simple command, you can add space to a ZFS pool without taking it offline.
Descendent (child) filesystems in ZFS take on the characteristics of the parent filesystem (compression, quotas, and available disk space). The pool concept in ZFS is fitting – a hard drive (or several) becomes a pool. We no longer have to define the exact size of a filesystem when we create it. Each filesystem has access to the same pool of space. However, it is simple to reserve a minimum amount of space for a filesystem and its decendents.
Creating new ZFS filesystems may seem strange at first since they are initially mounted under their parent filesystem. This is no problem since ZFS provides a simple and powerful mechanism for setting the mount point for a filesystem.
The distinction between ZFS pools and filesystems is worth repeating. A ZFS filesystem cannot exist outside of a ZFS pool. Creating a ZFS pool also creates a ZFS filesystem of the same name. Understanding the second part can help avoid confusion. This tech-recipe describes the simple step to list the ZFS filesystems configured on the system.
A previous tech-recipe demonstrated the command to create a ZFS pool using zpool. While this created a mounted filesystem, the fun does not stop there. The pool can be used in additional ways. This tech-recipe shows how to create more filesystems out of an existing pool.
Cygwin is a great tool for UNIX people stuck in a Windows world as it provides a vast assortment of UNIX tools in a Windows command prompt. One of the most powerful uses of Cygwin is as an X server. While it may be useful occasionally to run a single X application in its own window, that can be boring. As a more exciting option, it is simple (one command) to launch a full Solaris desktop session complete with login screen.
A JOIN is a way to connect related database tables by the common values between them. A left join contains all of the rows from the primary table plus related members of the second database if they exist. Using joins can significantly reduce the number of database queries required to render a web page. This Tech-Recipe describes how to do a left join in Symfony using Propel.
If you forget to carry your glasses, using your Windows Phone 8 with small text will be a problem. Luckily, you can use the magnifier to zoom the screen in and out to enlarge small text and make content clearer.
