Comprendre le fonctionnement des données structurées Google Search works hard to understand the content of a page. You can help us by providing explicit clues about the meaning of a page to Google by including structured data on the page. Structured data is a standardized format for providing information about a page and classifying the page content; for example, on a recipe page, what are the ingredients, the cooking time and temperature, the calories, and so on. Google uses structured data that it finds on the web to understand the content of the page, as well as to gather information about the web and the world in general. For example, here is a JSON-LD structured data snippet that might appear on the contact page of the Unlimited Ball Bearings corporation, describing their contact information:
VI and VIM editor: Tutorial and advanced features Vim Intro: This "vi" tutorial is intended for those who wish to master and advance their skills beyond the basic features of the basic editor. It covers buffers, "vi" command line instructions, interfacing with UNIX commands, and ctags. Learning Shell Scripting Language: A Guide from Newbies to System Administrator Linux is built with certain powerful tools, which are unavailable in Windows. One of such important tool is Shell Scripting. Windows however comes with such a tool but as usual it is much weak as compared to it’s Linux Counterpart. Shell scripting/programming makes it possible to execute command(s), piped to get desired output in order to automate day-to-day usages. In-fact automating these day-to-day task on server is an important task, system administrator has to perform and most of the admins achieve this by writing scripts to be executed as and when required. The most commonly used shell in Linux is BASH which stands for Bourne Again Shell.
One VPN To Rule Them All! June 18, 2014 | By Jean Taggart | | Share If you want to anonymize your traffic, one of the most common solutions available is to use a commercial VPN (Virtual Private Network) service. A VPN allows you to establish an encrypted tunnel over the Internet, and have your traffic exit out of a server on the VPN network. This exit point is usually configured to be in another country. Routing your traffic through such a service is what provides you with a certain level of privacy. To prying eyes, your traffic will appear to be emanating from a server on the network of the VPN service, therefore masking your location and somewhat protecting your personal identity.
Bash Shortcuts For Maximum Productivity It may or may not surprise you to know that the bash shell has a very rich array of convenient shortcuts that can make your life, working with the command line, a whole lot easier. This ability to edit the command line using shortcuts is provided by the GNU Readline library. This library is used by many other *nix application besides bash, so learning some of these shortcuts will not only allow you to zip around bash commands with absurd ease :), but can also make you more proficient in using a variety of other *nix applications that use Readline. I don’t want to get into Readline too deeply so I’ll just mention one more thing. By default Readline uses emacs key bindings, although it can be configured to use the vi editing mode, I however prefer to learn the default behavior of most applications (I find it makes my life easier not having to constantly customize stuff).

Fix "502 Bad Gateway" error on NGINX server after upgrading PHP I check my servers for upgrades on a regular basis and when I noticed yesterday that PHP was upgraded to version 5.5.12, I backed up everything of course (backup guide) and decided to upgrade which can easily be done with sudo apt-get dist-upgrade. Unfortunately I’ve ran into quite an annoying issue which I had not encountered before, all pages returned “502 Bad Gateway” errors. I’ve done this a numerous time and the upgrade went very smoothly. I was even asked if I wanted to keep local configuration files or not. Fedora 16 Linux on Samsung Series 9 (NP900X3A) Laptop Few words for a warm-up Few months ago I bought myself a brand new and shiny ultrabook from Samsung. It obviously came pre-installed with Windows7. I quickly rushed to wipe the evil OS out, before I did an SSD clone, just in case I will ever need Windows7 on this laptop again. Right, so it was time to install my favourite linux distribution - fedora! There was only fedora15 available back then, so I installed fedora15, which I am not going to talk about much, because few weeks later fedora16 was released, so I did a fresh install again.

Pull Data from Other Cells with Absolute and Relative References LVM HOWTO Logical volume management provides a higher-level view of the disk storage on a computer system than the traditional view of disks and partitions. This gives the system administrator much more flexibility in allocating storage to applications and users. Storage volumes created under the control of the logical volume manager can be resized and moved around almost at will, although this may need some upgrading of file system tools. The logical volume manager also allows management of storage volumes in user-defined groups, allowing the system administrator to deal with sensibly named volume groups such as "development" and "sales" rather than physical disk names such as "sda" and "sdb". One of the difficult decisions facing a new user installing Linux for the first time is how to partition the disk drive. With logical volume management, the whole disk would be allocated to a single volume group and logical volumes created to hold the / /usr and /home file systems.
