Profile folder - Firefox. From MozillaZine Knowledge Base This article is about Firefox's profile folder.

Profile folder - Firefox

See also Profile folder - Thunderbird and Profile folder - SeaMonkey. Firefox stores a user's personal information such as bookmarks, extensions, and user preferences in a unique profile. The first time you start Firefox, it will automatically create a default profile; additional profiles can be created using the Profile Manager. The settings which form a profile are stored in files within a special folder on your computer — this is the profile folder. Finding the profile folder The Firefox profile containing your user data and settings is not found in the installation directory but rather in a separate location on your computer. Using the Help menu - Firefox 3.6 and above In Firefox 3.6 and above, you can open your profile folder directly from the Firefox Help menu, as follows: [1] [2] In the Firefox Button or menu bar, click "Help" and select "Troubleshooting Information".

Centos - Flush-0:n processes causing massive bottleneck - Server Fault - Iceweasel. 21.10. Linux Performance Guide - Iceweasel. The key to achieve good performance on reads and writes is to have lots of RAM since disks are so slow.

21.10. Linux Performance Guide - Iceweasel

This guide will focus on achieving good write performance on a Linux kernel based operating system. If you have not already read the information available in Chapter 21, Configuration & Performance do that now to get some basic knowledge on memory mapping and store files with Neo4j. This section will guide you through how to set up a file system benchmark and use it to configure your system in a better way. Create a large file with random data. The file should fit in RAM so if your machine has 4GB of RAM a 1-2GB file with random data will be enough. If you have a standard hard drive in the machine you may know that it is not capable of transfer speeds as high as 1.4GB/s. Next we will use a small utility that simulates the Neo4j kernel behavior to benchmark write speed of the system.

The utility will be given a store file (large file we just created) and a name of a log file. 21.10.2. Overview of RAMFS and TMPFS on Linux - Iceweasel. This is a guest post written by SathiyaMoorthy.

Overview of RAMFS and TMPFS on Linux - Iceweasel

Using ramfs or tmpfs you can allocate part of the physical memory to be used as a partition. You can mount this partition and start writing and reading files like a hard disk partition. Since you’ll be reading and writing to the RAM, it will be faster. When a vital process becomes drastically slow because of disk writes, you can choose either ramfs or tmpfs file systems for writing files to the RAM. Both tmpfs and ramfs mount will give you the power of fast reading and writing files from and to the primary memory. 1.

Stop Using “rm” on the Command Line (Before It’s Too Late) - Iceweasel. True story… While writing a Python script one day to do a little screen scraping and reporting, the topic of data loss came up between a friend and myself.

Stop Using “rm” on the Command Line (Before It’s Too Late) - Iceweasel

I was bragging that I had never in my life accidentally lost a single file or piece of data that I wasn’t able to recover. Literally seconds later, while intending to rename my script using “mv”, I accidentally typed “rm” instead and deleted it. That was just about the last time I used “rm”. I now use a script which, for no particular reason, I call “rr” . #! Just make the script executable (chmod 755 rr), drop it in your path, and forget “rm” ever existed. As always, there are several other ways of doing this (remapping “rm”, making an alias, using the Finder, etc.), so pick the way that works best for you.

Admin Linux » Blog Archive » Personnaliser le prompt

Souvent négligé par de nombreuses distributions, le prompt est la première source d’information transmise à l’utilisateur ou à l’administrateur. Parmi les données utiles qu’il peut transmettre, on peut trouver : la couleur pour indiquer la différence entre les sessions “root” et les autres,la localisation (dans quel répertoire sommes nous),l’heure,etc… La variable de personnalisation du prompt sous Bash et ses dérivés est “PS1″. Dans la plupart des distributions le prompt est initialisé dans “/etc/profile” ou dans les fichiers de configuration de bash (“/etc/bash/bashrc”, “/etc/bash.bashrc”).

L’utilisateur désireux de modifier l’affichage de son prompt définira ses nouveaux paramètres dans “~/.bashrc” ou “~/.bash_profile”. Les séquences d’échappement pouvant être utilisée pour le prompt sont principalement les suivantes : L’application d’une couleurs est définie par \033[<code couleur>m. Par exemple :
