Linux Tips

I found this in the ubuntu documentation. Tasksel is an installation system that is an integral part of the Debian installer; it is also included in Ubuntu. Tasksel groups software packages by tasks and offers an easy way to install all the packages needed for that task. It provides the same functionality as using conventional meta-packages. Tasks List Tasks are defined in .desc files found in /usr/share/tasksel. Debian derivatives can easily add tasks. The default list available in Ubuntu can be viewed with this command-line: $ sudo gedit /usr/share/tasksel/ubuntu-tasks.desc Installation Since Ubuntu 6.10 (Edgy) tasksel has been included as part of the base installation. Tasksel is present on all versions of Ubuntu's installer, but previously was not installed on the base system. Usage To run tasksel, at the command line, type $ sudo tasksel the tasksel menu will be shown: Already-installed tasks will have an asterisk beside their name. Select a task by scrolling down and pressing

These are NOT FINAL! THEY ARE ONLY FOR BRAINSTORMING/EXPLORATION! Initial Theme Mockups for Firefox 4.0 Version A - Tabs-on-Bottom Possibly add a Bookmarks widget as an upfront replacement for the Bookmarks menu/Bookmarks toolbar (option to turn those on would remain). Version B - Tabs-on-Top The more contentious Tabs-on-Top concept. Positives Save Vertical Space Efficiency/Remove Visual Complexity - Right now the tabs have to be connected to something. So we are adding an extra visual element for them to connect to. Shorter Mouse Distance to Page Controls Negatives Breaks Consistency/Familiarity - Moving things confuses existing users. Title is MIA - With the space removed from the titlebar you only get the truncated version in the tab. Longer Mouse Distance to Tabs - Takes longer to mouse to a tab. Lost Space - Sandwiched in between the application icon and the window widgets you lose some space. Combo Stop/Refresh/Go Button. Attached at the end of the location bar. Turns green whe

Looking for an application that would allow you to take notes, draw sketches and insert images , it's like i have found for you - Jarnal . Jarnal is an Open Source platform and written in Java, similar to Windows Journal . Supports collaborative writing, a feature that allows multiple authors to edit a single file in real time over a network. Another important feature is that it allows you to create and export presentations created with formats pdf, html, and text (only text, the figures are not exported) . Being written in Java, only requires at least Java 2 1.4.2. This application can be found in the openSUSE Build Service under the repository Open Source Software by the method or one-click install . The official website of the project can be found here . For demos: There is a simple on-line demo and and a more advanced (and fun) demo demonstrating networked usage . See what the developers says... Why is this program better than Microsoft Windows Journal or One-Note? Because

I found this native emulator for GNU / Linux called lxdream . lxdream is a new Sega Dreamcast emulator for Linux. To install simply download the file you need for your distro from this link You can also download through the official repositories. For Ubuntu First edit the list by entering the terminal and typing: $ sudo gedit /etc/apt/sources.list Enter the following lines. deb http://www.lxdream.org/debian unstable main deb-src http://www.lxdream.org/debian unstable main Save and type $ sudo apt-get update $ sudo apt-get install lxdream You must download and flash the bios rom Dreamcast Find the program in Menu> Applications> Games> lxdream , select and open the program, the first thing you should do is go into Settings> Routes and tell the program where files are located and bios flash rom you downloaded.

For this, the easiest way is to use one-click install . Once installed, go to YaST , and as root user remove all matters related to NetworkManager: Afterwards, go to Network Devices> Network Settings , which warns us that the network is currently controlled by NetworkManager and .... Click OK. Changes to the Traditional Method with ifup option and uncheck Change Default Route via DHCP . Then in the Summary tab, select the wireless card, and click on the Edit button. In my case, it is necessary to switch to DHCP only with version 4. In the General tab, uncheck the Enable Device Control for users not using Root KInternet . With this we are able to connect using Wicd. You must restart the machine. If for some reason, when asked to restart the root password to run Wicd, it can be solved by opening a terminal as Root and entering the following line: chkconfig wicd on It may also be unable to see the icon in the system tray so it would be necessary to have installed the packages for gtk

Here we have created a launcher for applications, operating through the terminal, this may disadvantage those who wish to launch or create links to these applications. To do this follow these three steps: 1. Create a launcher with the terminal of our choice: For example, my favorite is terminal Xterm and I run Moc: The command would look like this: xterm -e mocp Here are a list of terminal emulators for you to use: gnome-terminal -x mocp sakura -e mocp konsole -e mocp xterm +u8 -e mocp 2. Create a script:. Open a new file with our favorite text editor and put the following: #!/bin/bash xterm -e mocp Save the file and then give it execute permissions: # chmod +x filename 3. Create a hotkey for the program: This depends on the program or environment that are using (can be in gnome, kde, Openbox) or any program(for that as xbindkeys) I hope you can use them now.

By the time now, we all know that all applications installed on our PC are slowly filling our system with files, then comes a time when controlling everything in our computer becomes virtually impossible. If you want your computer to be running like the first day you had it. Put FSlint the task of cleaning and organizing your Linux very easy. Thanks to the implementation of FSlint . With a single click we can delete duplicate files, empty folders, temporary files, check the installed packages, links incorrect blanks along with other tasks that will allow us to maintain our Linux in optimal conditions.

I just installed urlfilter unfortunately some users are recreated popularity site NSFW, the problem is not to "entertain" with this type of site, but sometimes these places up dirt half of computers and then to clear it we have to invest a good time running antivirus and AntiSpyware. The installation of urlfilter has no problems; But, the detail is applied to all the locks on network users. What if I want to leave a machine without locks?. So, we have to resort to give permission by IP addresses, is not the only solution but is very easy to implement. Based on the urlfilter squidGuard , the documentation of this project can be applied practically without problems. The first is to locate the configuration file for squidGuard in IpCop , place it in: /etc/squidGuard/squidGuard.conf This is the file we have to change. I am still awaiting a change that if I lost my web changes so you have this in mind. The documentation of squidGuard finding rules based on source IP addresses t

We can download the new version of Linux Mint Linux Mint which is 7 Gloria, a distribution which has always called attention with its menu, this time with further improvements. Mint7 Linux is based on Ubuntu 9.04 Jaunty Jackalope and is completely compatible with their packages and repositories and comes with GNOME 2.26 desktop environment.

Install RedHat RHEL 4 AS to the USB Hard Drive 1. Install RedHat RHEL 4 AS to the USB Hard Drive Boot RHEL4 Installation CD, enter "expert". Partition your USB Hard drive manually. In my case, I created 1GB /dev/sda1 mounted as /boot and /dev/sda5 mounted as / (root), I also have /dev/sda7 SWAP partition. After installation, boot from the RHEL4 Installation CD again, type "linux rescue", don't let the installer mount the USB hard drive partitions. 2. Mount partitions # mount /dev/sda5 /mnt/source # mount /dev/sda1 /mnt/source/boot # chroot /mnt/source 3. Restore initrd image # cp /boot/initrd-2.6.9-5.EL.img /tmp/initrd.gz # cd /tmp # gunzip initrd.gz # mkdir /tmp/a # cd /tmp/a # cpio -i < /tmp/initrd (Output: 2078 blocks) 4.

In Linux there is a variety of audio players and some really very good, not for the fact that play music correctly, but they do all the comforts and accessories that we offer. I made a small collection that I think are the best and most well known, it is clear that this is based on my tastes so I strongly recommend to comment on this post which is more suited to your tastes: Amarok: which i like use every day to listen to the music, a lightweight player that has everything you need, multiple playlists, integration with other KDE applications, it downloads lyrics from the Internet, socialized through Last.FM, information of the artists on wikipedia, apparently set by CSS ... as you can see an endless list that makes it my favorite player without doubt. Exaile: uses GTK + and the features I'm very similar to those found in Amarok. Banshee: I have to stress this for its ease of operation. And the library is great for people who have a large collection of songs on your hard disk. Y

Wine one of the best known Windows emulation systems under Linux platform now has an excellent graphical environment called WineXS. Many Windows applications when installed in Wine can give us some problems in most cases are resolved by changing the settings, from now on you can do so much easier with WineXS. As you can see in the image WineXS includes an installer and uninstaller software, add fonts, change the registry, edit the configuration and many among others. WineXS is a wonderful tool for Wine and with it you will not need to re-use Windows anymore. Download WineXS 1.4.2

A great tool for doing this is 'Phatch', a free and open source platform that will allow editing of images in bulk and easily. The properties that we can change are size, resolution, size limit, transpose images, watermarks, borders, shadows, text ... great tool for those who work with many images. Phatch alter images in bulk . In the picture we can see some of its main functions, but we can select by clicking on the top and select the option ALL. Download Phatch tool for the mass modification of images.

Arista is a wonderful video format converter that anyone can use without any knowledge, its performance is really very simple, but its main purpose is to streamline the full process of converting a video giving a few options that are easily understood for us users: Convert to Apple iPod, Cowon D2, Computer, DVD Player, Sony PSP or Sony Playstation 3. One of the features I liked most of Arista is the ability to preview video looks like without having to wait until it finishes its conversion, in this way can we know if we feel we must correct or select another. Arista also allow us to extract and convert video or DVD directly from any camera connected to your PC without the need for additional software. Download Arista

Sometimes it is necessary to put restrictions on users, if you have a computer to the public or used by many people. For example a library, we can not allow anyone to put their taste or change certain settings. In your Gnome desktop environment there is a tool called Pessulus that will control these profits that can manage users. Pessulus is divided into 4 parts, General , allowing us to configure access to the command line, printers and the ability to save files. Panel , where you can block access to applets and controls such as blocking off and restart the computer. Browser , allowing us to configure all the properties that can change the user's browser Gnome Desktop , which controls user sessions. From this application you can control the vast majority of the options for Gnome. To install just have to type in your terminal: $ sudo apt-get install pessulus (or equivalent depending on distribution)

Monitor the CPU usage of applications that we use, it is recommended if you need to maintain a good performance on your system, sometimes in our system we have applications that should not stop working and we need some free resources on your computer for them. Linux can prevent other applications to consume these resources and the applications work properly within a cpu limit. To install in ubuntu: $ sudo apt-get install cpulimit It is in the universe repositories. To install it on any other Linux distribution follow this: $ wget http://downloads.sourceforge.net/cpulimit/cpulimit-1.1.tar.gz $ tar-zxf cpulimit * xxx.tar.gz $ cd cpulimit-xxx $ make Use it To use it, you will need to know the name of the application or PID, once you know it: Examples of use If we want to avoid that Firefox does not exceed 30% of CPU usage type cpulimit -e firefox -l 30 In the case of wanting to limit the process with PID 3675 to use only 40% CPU at maximum, for that type on your console as f

301 redirect is the most efficient and Search Engine Friendly method for webpage redirection. It's not that hard to implement and it should preserve your search engine rankings for that particular page. If you have to change file names or move pages around, it's the safest option. The code "301" is interpreted as "moved permanently". Below are a Couple of methods to implement URL Redirection IIS Redirect In internet services manager, right click on the file or folder you wish to redirect Select the radio titled "a redirection to a URL". Enter the redirection page Check "The exact url entered above" and the "A permanent redirection for this resource" Click on 'Apply' ColdFusion Redirect <.cfheader statuscode="301" statustext="Moved permanently"> <.cfheader name="Location" value="http://www.new-url.com"> PHP Redirect <?

Internet Relay Chat (IRC) is a form of real-time Internet text messaging (chat) or synchronous conferencing. It is mainly designed for group communication in discussion forums, called channels, but also allows one-to-one communication via private message as well as chat and data transfers via Direct Client-to-Client. IRC client software is available for virtually every computer operating system that supports TCP/IP networking. IRC is based on a line-based structure with the client sending single-line messages to the server, receiving replies to those messages and receiving copies of some messages sent by other clients. The basic means of communication in an established IRC session is a channel. Channels in a server can be displayed using the IRC command LIST that lists all currently available channels. Channels that are available across an entire IRC network are prepended with a '#', while those local to a server use '&'. Other non-standard and less common channel

This is a port of Tesseract OCR engine that supports Indic script. The aim of this project is to add Indic script support to the Tesseract OCR engine, which currently does not support connected script such as devnagri. This includes adding some routines to the existing code base, training the engine with sample images and then testing for accuracy for subsequent debugging and refinement in the algorithms. Tools and used software Tesseract OCR engine 2.03 http://code.google.com/p/tesseract-ocr/ Gimp 2.2.17 http://www.gimp.org/ bbtesseract (GUI for editing training data, such as box files) 0.5.34 http://code.google.com/p/bbtesseract/ Project Plan: Take the input image and then manipulate it in a manner so that it then fit to be processed by the Tesseract OCR engine. For devnagri scripts, it translates to clipping the maatra(shironaam) between successive characters. Online Documentation: http://code.google.com/p/tesseract-ocr/wiki/TesseractProjects , http://tesseract-ocr.repairfaq.or

Tesseract-ocr was an OCR Engine that was developed at HP Labs between 1985 and 1995... and is now at Google. The Tesseract OCR engine was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but it is probably one of the most accurate open source OCR engines available. The source code will read a binary, grey or color image and output text. A tiff reader is built in that will read uncompressed TIFF images, or libtiff can be added to read compressed images. Important Download Information: The language data files are separate from the code! See the ReadMe wiki for installation and usage information! Additional installation and usage information can be found in the FAQ wiki. Supported Platforms The developers are regularly testing on the following platforms: Ubuntu 6.06 (x86/32, x86/64) Ubuntu 6.10 (x86/32, x86/64) Windows (x86/32) with Visual C++ Express 2008 The upcoming 3.00 release will probably include: Page layout analysi

This tutorial will show you how to customize and remaster your ubuntu 9.04 jaunty using a jaunty iso file. 1. Create a work directory # mkdir jaunty 2. Create the following directoires # mkdir jaunty/cdrom # mkdir jaunty/tmp # mkdir jaunty/root 3. Mount the jaunty iso image on jaunty/cdrom directory # mount -o loop jaunty.iso jaunty/cdrom 4. Copy everything from the cdrom to jaunty/image directory # cp -r jaunty/cdrom jaunty/image 5. Now the image directory has the content of your cdrom We are going to rebuild filesystem.squashfs under jaunty/image/casper Move the filesystem.squashfs image to jaunty/tmp directory # mv jaunty/image/casper/filesystem.squashfs jaunty/tmp 6. Mount the filesystem.squashfs under jaunty/root direct # mount -o loop jaunty/tmp/filesystem.squashfs jaunty/root 7. Copy the contents of fileystem.squashfs to jaunty/remaster # cp -r jaunty/root jaunty/remaster 8. Copy resolv.conf and sources.list from the host system # cp /etc/resolv.conf jaunty/remaster

Actually the usbserial module has been added to the kernal in ubuntu 9.04 (jaunty). Everyone using a phone or usb device to access internet will be having problem with that. To solve this please follow the following steps. It is possible to pass the ids as kernel parameters. 1. Get your device's vendor and product ids. Connect your device and type at terminal: $ sudo lsusb 2. Open your menu.lst file to edit. $ sudo gedit /boot/grub/menu.lst 3. Find your ubuntu kernel line. kernel /boot/vmlinuz-2.6.28-13-generic root=UUID=c54f5577-285d-455d-8...... 4. Add this line below it usbserial.vendor=0x VVVV usbserial.product=0x PPPP where VVVV and PPPP are vendor and product ids. Restart your system, for the changes to take effect.... Now you need not modeprobe after connecting your device
