I am definitely a rsync user, and for anyeone whom is not allergic to command line i do not see why searching for another utility … Wrap an well thought rsync command inside a desktop short-cut and here we go! Rsnapshot is also something i liked

ownCloud has come a long way since the last time I gave it a look. What I’ve covered in this post doesn’t touch everything that ownCloud can do — such as its WebDAV support. But if you’re looking for an online storage and syncing app that keeps your files under your control, ownCloud is definitely worth a close look.

Meine private Top 10 oder der Anwendungen für die Kommandozeile, vielleicht sollte ich eher sagen, dass das meine Lieblingsanwendungen sind und nicht unbedingt die, die ich am häufigsten benutze (dann müsste wenigstens sudo noch dazu).

Was ist eigentlich Linux, was der Kernel, was eine Distribution, und wofür steht GNU? Dabei geht er auch auf vermeintliche und echte Stärken und Schwächen des freien Betriebssystems ein: Software, Security, Support, Spiele und mehr.
Bevor er zum Praktischen und Technischen kommt, porträtiert der Autor außerdem noch die Open-Source-Community mit ihren Mailinglisten und Konferenzen und erklärt dem Linux-Neuling, wo er sich Hilfe holen kann.

Man sitzt grübelnd vor dem Rechner, tippt nichts, bewegt keine Maus - aber plötzlich hört man die Festplatte anlaufen. Was hat sie aufgeweckt: Der Indexer der Desktop-Suche, eine E-Mail, oder gar Malware? Oder: Wieviel Schreiboperationen landen bei allen Buffern und Caches tatsäclich auf der Platte? Blktrace gibt die Antwort.

Linux Command Line Cheat Sheet

Looking for a no-nonsense command-line tool for monitoring your GNU/Linux system? Glances might be right up your alley. This neat little Python-based utility provides an overview of all key system aspects, including CPU load, disk storage, memory consumption, and network activity. More importantly, the utility does a good job of presenting monitored data in an easy-to-follow manner.

Back up drives and partitions to image files or other drives Copy a drive block-for-block directly to another drive Supports a very large number of file system types Can reinstall GRUB 1 and 2 after cloning Can access image files on local disks, an SSH server, SAMBA server, or NFS server

The ebook editor is an easy to use yet complex enough program for aspiring authors who would like to create books in epub format. The software is available for Windows, Linux and Macintosh systems at the project’s Google Code web page.

So to be more specific with the commands, here's what I did to enable user theme extension: Code: $ sudo add-apt-repository ppa:ricotz/testing $ sudo apt-get update $ sudo apt-get install gnome-shell-extensions-user-theme (if you don't already have ppa-purge installed) $ sudo apt-get install ppa-purge $ sudo ppa-purge ppa:ricotz/testing

UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on Windows, Linux, and Mac OS X. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.

So if you believe in the principles behind UNIX and Open Source, please don't write software which requires any of the Gnome/KDE and DBus API. Writing X11 programs with xcb and proper RPC APIs like SUNRPC or Thrift should be more than good enough. So, please support choice and freedom by implementing programs the right way instead of the Linux/Gnome/DBus way.

You know how you can control your Linux box through the terminal command line? Well, if you have SSH set up, you can also control a remote computer over the network. This is really useful for taking control of things like webservers.

What is FreeNAS you say? Put simply, it's is an operating system based on FreeBSD that brings with it a snazzy web interface for management, and all the protocols you need to share files between Windows, Mac and Linux. In other words, a perfect solution for your digital bookshelf. Let's get to it.

With Déjà Dup it's very easy to configure periodic backups. Do do them, just click on "Schedule" and decide how often you want to run your backups, and how long for.

Yes, it's that simple. With Déjà Dup, there is really no excuse not to backup anymore.

But if you want – nay need – to record something from a radio station, a live web-cast performance or some other ‘audio’ event playing on your computer in Ubuntu how can you do so?

As the name somewhat obviously spells out ‘Audio Recorder’ is a small utility for recording audio. It’s able to capture output from your soundcard, microphone, web browser – even Skype; basically if it plays through your speakers Audio Recorder can record it.

Arduino is an open embedded hardware and software platform designed for rapid creativity. It's both a great introduction to embedded programming and a fast track to building all kinds of cool devices like animatronics, robots, fabulous blinky things, animated clothing, games, your own little fabs... you can build what you imagine. Follow along as we learn both embedded programming and basic electronics.

What Does Arduino Do?

Arduino was invented by Massimo Banzi, a self-taught electronics guru who has been fascinated by electronics since childhood. Mr. Banzi had what I think of as a dream childhood: endless hours spent dissecting, studying, re-assembling things in creative ways, and testing to destruction. Mr. Banzi designed Arduino to be friendly and flexible to creative people who want to build things, rather than a rigid, overly-technical platform requiring engineering expertise.

So what is the lesson here?  On the community side, we may have the greater challenge.  We can argue until we’re blue in the face about all of the great benefits of community development, but we can’t indemnify graphics IP vendors against lawsuits when the details of their designs are revealed in open-source drivers.  This obviously isn’t guaranteed to happen, but it only has to happen once to foul up the works.  On the vendor side, with a little help, trust and understanding you get a Linux driver stack, lots and lots of testing on a variety of platforms and an active community supporting your platforms.  This isn’t a free lunch, though, and it is important to seed the development community with engineering resources; this improves the community as well as the software it produces.

They say that when one door closes on you, another opens. People generally offer this bit of wisdom just to lend some solace after a misfortune. But sometimes it's actually true. It certainly was for Ken Thompson and the late Dennis Ritchie, two of the greats of 20th-century information technology, when they created the Unix operating system, now considered one of the most inspiring and influential pieces of software ever written.

The highest single source of revenue for Linux Mint isn’t the donations, it isn’t ads on the website, it is the default start page in Firefox. This simple search plugin is estimated to generated from 2 to 40 times more money than the start page itself. If this proves to be the case we’ll be in a position to grow and to achieve things we never dreamed off before.

Create and configure printer sharing
Configure integration between Samba and the Common UNIX® Print System (CUPS)
Manage Windows® print drivers, and configure downloads of print drivers
Configure the [print$] share
Understand security concerns with printer sharing
Set up and manage print accounting

The Show Don’t Tell policy also applies to feature comparisons. Let’s say you want to outline the salient features of Linux. Instead of giving a huge lecture about how virus-free, how fragmentation-free, how fast the desktop is, just show it to them. Take their Windows/Mac laptop and put it beside your own desktop. Start a timer and show your friend how fast it boots. I hate to repeat, but just show it, don’t talk about it.

If you are fan of command line like me and agree that in many situations it’s better/easier to use terminal than graphical interface, you should try terminal plugin for nautilus file manager. This smart plugin makes it possible to open popup terminal in any directory you opened in nautilus and use it for file manipulations or anything you want. If you still don’t have it installed you definitely should.

I’ve recently been using Debian a lot (mostly Debian Wheezy (aka testing)), So I’ve decided to adapt my Fedora 15 post installation setup & tips article for Debian. Here are some of the common things I add to a typical “graphical desktop” Debian installation as well as some tips and tricks that you’ll hopefully find useful. Btw, I highly recommend you to use the netinstall Debian distribution - that way you’ll get an up-to-date installation immediately and you won’t have to download huge installation images.

This article will be of use mostly to people using Debian as a desktop OS (with GNOME as their desktop environment) - it doesn’t discuss any server configurations.

libimobiledevice is a software library that talks the protocols to support iPhone®, iPod Touch®, iPad® and Apple TV® devices. Unlike other projects, it does not depend on using any existing proprietary libraries and does not require jailbreaking. It allows other software to easily access the device's filesystem, retrieve information about the device and it's internals, backup/restore the device, manage SpringBoard® icons, manage installed applications, retrieve addressbook/calendars/notes and bookmarks and (using libgpod) synchronize music and video to the device. The library is in development since August 2007 with the goal to bring support for these devices to the Linux Desktop.

"Android ist allerdings ein gewisser Sonderfall: Die benutzen zwar einen Linux-Kernel (allerdings mit vielen Patches und Subsystemen, die so nicht im Mainline-Kernel aufgenommen werden), der Userspace ist allerdings google Android. Nix mit GNU, keine glibc, keine GNU sonstwas-utils etc. Das Framework ist Java-basiert und haben nichts mit normaler Linux-Entwicklung zu tun. Aber who cares. Linux hat sowieso schon gewonnen. Und diese Fragmentierungs-Geschichte kann ich echt nicht mehr hören. Da könnte man gleich behaupten, es gäbe kein Linux, sondern KDE, Gnome etc. und kein Windows, sondern die Lenovo Toolbox, die Dell Wireless Utilities etc. Die Apple-Gehirnwäsche wirkt, bald dürfen alle nur noch iOS verwenden."

Bei der tatsächlichen Entwicklung jedoch (des Linux-Kernels, von Bibliotheken, von Anwendungen, …), da fließt es prächtig und kräftig. Wenn jemand (ja, z. B. ein Distributor) etwas am Linux-Kernel patcht, dann fließt diese Änderung bei den meisten Distributionen (nach gewünschter Zeit) ein.

Linux may not be the most popular OS around, but that doesn't mean it we're going to sit here and ignore it. Here are our favorite downloads for everyone's favorite open source operating system.

Im Prinzip ist die Dockstar auch nur ein kleiner Homeserver, mit Debian bespielt kann man damit also alles anstellen, was auch ein "normaler" Homeserver packt. Allerdings sind natürlich Grenzen in der Leistung gesetzt. So ist das Hosten einer oft besuchte Websites eine schlechte Idee für die Dockstar, auch ein OpenVAS Server wäre eine sehr schlechte Wahl, aber trotzdem gibt es genügend Serverdienste, die unter Linux mit wenigen Ressourcen zurechtkommen und von denen habe ich hier eine Liste mit Beiträgen aus unserem Blog und Wiki erstellt.

Wenn es um Webserver geht, fällt den meisten Administratoren als erstes Apache ein, der in der globalen Statistik des Web auch an erster Stelle steht. Kleinere und schnellere Alternativen gewinnen jedoch immer mehr Anhänger, so zum Beispiel Lighttpd und Cherokee. Als zusätzlicher Wettbewerber stieg vor einiger Zeit der Nginx-Server (ausgesprochen englisch "Engine-ex") in den Ring. Er steht für hohe Performance, Stabilität, umfangreiche Features, einfache Konfiguration und geringen Ressourcenverbrauch. Das Resultat der Bemühungen des Programmierers Igor Sysoev verrichtet seinen Dienst in vielen großen Sites, zum Beispiel Wordpress.com, Hulu und Linuxquestions.org. Ungewöhnlich: Außer als Webserver kann Nginx auch als Proxy für die Mail-Protokolle IMAP und POP3 auftreten.

CrunchBang is a Debian GNU/Linux based distribution offering a great blend of speed, style and substance. Using the nimble Openbox window manager, it is highly customisable and provides a modern, full-featured GNU/Linux system without sacrificing performance.

Wireshark is an open source network packet analyzer. Without any special hardware or reconfiguration, it can capture live data going in and out over any of your box's network interfaces: Ethernet, WiFi, PPP, loopback, even USB. Typically it's used as a forensics tool for troubleshooting network problems like congestion, high latency, or protocol errors — but you don't want to wait until your network is in trouble to learn how to use it. This weekend, why not take a look at your network traffic, and learn how to use Wireshark to your advantage?

"I think Qt has a lot to offer people who want to develop applications for (and on) Ubuntu, particularly now. It already powers popular cross-platform applications like VLC, not to mention the entire Kubuntu distribution," he concludes, "It has strong commercial backing as well as a large developer community. No single solution will meet all developers' needs, of course, and Ubuntu supports multiple toolkits and frameworks for this reason, but Qt seems like a great tool to have in our toolbox for the road ahead."

Seitdem immer mehr Leute USB-Festplatten oder -Sticks benutzen und die Distributionen mehr und mehr auf udev setzn, umso überkommener ist es mit Device-Pfaden zu arbeiten, denn sie können sich sehr schnell ändern. Einige behelfen sich, indem sie ihre Festplatten oder USB-Sticks über udev feste Devices zuordnen, aber wirklich toll und einfach ist diese Lösung nicht. Hier bieten sich UUIDs an, da sie eine feste Zuordnung bieten auch wenn sie Device-Namen verschieben sollten, weil man USB-Stick und Festplatte gleichzeitig nutzt oder eine zweite Platte einsetzen möchte.

Ubuntu 10.10 Server Edition extends Canonical's CloudInit configuration tool. This lets you set a default locale, set the hostname, generate and set up SSH private keys, and set up mount points on Ubuntu instances during boot-up when running in the cloud.

Linux wird im mobilen (Smartphones mit Android oder WebOS) und semimobilen Bereich (kommende Tablets mit Android, WebOS, kommende Netbooks mit Chrome OS) zunehmend erfolgreich. Diese Bereiche sind die kommenden Wachstumsbereiche im Computermarkt. Teilweise sind sie es bereits heute.

Interessant dabei ist, dass Linux nicht Linux genannt wird und unter verschiedenen Namen im Markt nach vorn marschiert. Deswegen dürften viele diesen Siegeszug übersehen. Gleichzeitig liegt es natürlich an der Open-Source-Herangehensweise, dass Linux hier erfolgreich ist. Google (Android und Chrome OS) und Palm (WebOS; Palm und WebOS gehören jetzt zu HP) stehen auf den Schultern derer, die Linux entwickelt haben und weiter entwickeln. Sie müssen für ihre eigenen Betriebssysteme nicht bei Null anfangen.

OStatic:

As Steven Vaughan-Nichols notes, Hewlett-Packard, the number one PC seller on the planet is trending toward becoming a significant Linux distributor. In acquiring Palm, HP also acquires the Linux-based WebOS, and if HP is smart, it will pursue a very open strategy with WebOS, possibly on mobile phones, and possible on iPad-like tablet devices.

[..]

Google, too, has demonstrated how powerful Linux can be when it’s not branded as Linux. Android is a hugely successful mobile OS, based on Linux. Google’s upcoming Chrome OS is Linux-based and was developed with the help of the Canonical team. Increasingly, Linux is having an impact on desktop and mobile technology users when it isn’t called Linux.

Das Jahr, in dem Linux auf dem Desktop einzieht, mag vielleicht nie kommen. Aber vielleicht ist das auch nicht mehr wichtig, wenn die Bedeutung des Desktops künftig marginalisiertwird.

Linux wird auf den Geräten von morgen eine bedeutende Rolle spielen, wenn auch in unterschiedlichen Gewändern. Die Computerwelt wird gerade umgekrempelt und Linux ist mittendrin.

Was macht eigentlich Microsoft?

To help guide newbie's in getting off to a pain-free start with the worlds greatest free Operating System we publish a traditional “10 things to do after installing Ubuntu” article, consisting of the usual fare such as how to get flash and multimedia codec's up and running, enabling 3D drivers, etc.

So, to better help make an awesome, relevant and above-all-else useful 10-point guide for post-Lucid installations I thought it’d be beneficial to see what you consider your “top 10” must do’s and factor the most popular in. After-all one nerds' Ubuntu Tweak is another geeks BleachBit !

Regardless of how you feel about the Linux desktop, this is one area in which Linux can have a real impact, both financially and productively, and any small or home office has the potential to be transformed by just switching one application or two to their open source equivalents. So, we've put together this guide to helping people in offices switch to Linux, explaining what tools are available for different jobs and how best to maximise compatibility with other Windows users. Read on!

The office is traditionally the domain of Microsoft, a costly and sometimes frustrating environment where you have to constantly keep on top of updates, patches and the latest versions to stay in the loop. Free software offers an escape from this cycle, and more importantly, an alternative.

Linux and free software can offer a breath of fresh air, and you don't even have to jump feet-first into a new operating system: cross-platform open source applications enable you try the alternatives before you ma

Most Linux distributions come with the md5sum utility so installation is usually unnecessary. We are going to use the Ubuntu 8.10 LiveCD for the following example:

Check the iso file

Manual method

First open a terminal and go to the correct directory to check a downloaded iso file:

*

cd download_directory

Then run the following command from within the download directory.

*

md5sum ubuntu-8.10-desktop-i386.iso

md5sum should then print out a single line after calculating the hash:

*

24ea1163ea6c9f5dae77de8c49ee7c03 ubuntu-8.10-desktop-i386.iso

But what is AppArmor? AppArmor is a security module implementation of name-based access controls. In other words, AppArmor protects your system against the exploitation of program flaws and compromises. This protection is done via profiles that will set a program to either “complain” or “enforce” against wrong doing.

In this article I will show you how to install AppArmor and how to use it to set an application in either “complain” or “enforce” mode.

I’ll simply say that it’s an exciting time to be interested in portable and mobile computing. There are options for all sorts of users and developers, and those options are increasingly robust and competitive. As I’m getting ready to publish this, even Microsoft is making a respectable play for mobile hearts, minds, and wallets.

In short, there’s no reason to feel trapped by your current platform. Go out and explore. You may find that you like where you’re at, but you’ll definitely learn something about the creativity and diversity of the tech landscape if you look around.

The GNU/Linux systems have reached an important level of maturity, allowing to integrate them in almost any kind of work environment, from a desktop PC to the sever facilities of a big company.

In the module called "The GNU/Linux operating system", the main contents are related with system administration. This book is the main documentation for the module.

We will learn how to install and configure several computer services, and how to optimise and synchronise the resources.

The activities that will take place in this module cover the studied topics in a practical approach, applying these concepts in real GNU/Linux systems.

Winning the middle ground

Ultimately, BitDefender had the performance and accuracy needed to win. It wasn't the fastest on test, but neither was it the slowest. Changing the options makes a big difference to the performance, but we're of the opinion that if you want to run antivirus software, you should run it at the most paranoid level available. BitDefender competently found all the virus files, identified them and suggested appropriate action, so it's difficult to see what more it could do. It was simple to use and the updates to the virus database seem to be regular. The command line app is configurable and versatile too, so you can easily set up regular scans.

With strong competition from Beagle, especially in the number of search options, Recoll just manages to cling on to the top spot. Forcing the user to index the system manually is actually a clever design. For anyone who's convinced that desktop search tools eat up too many resources, this offers the opportunity to index the system at a convenient time. It should therefore help Recoll to attract users who'd normally distance themselves from desktop search tools.

Defining the keywords to look for and avoid for each search helps Recoll accurately locate the correct file each time. Other tools should also consider adopting this feature.

Diese Art der Sicherung ist nicht wirklich zu empfehlen, da die Image-Datei die gleiche Größe wie die gesicherte Partition hat. Daher ist es sinnvoller, das Image zu komprimieren. Der folgende Befehl erstellt ein komprimiertes Image der Partition /dev/hda1 und speichert dieses in die Datei image-compress_hda1.img im Heimatverzeichnis. Durch das Weglassen von of im Befehlsaufruf werden die Daten auf die Standardausgabe geschrieben, wo sie dann per Pipe-Operator an gzip weitergeleitet werden:

dd if=/dev/hda1 | gzip -9 > ~/image-compress_hda1.img.gz

Betreibt man ein Ubuntu- oder Debian-System über einen längeren Zeitraum, so sammeln sich über die Monate und Jahre eine ganze Reihe von Kerneln an. Bei Sicherheitsupdates oder auch Upgrades auf ein neueres Ubuntu oder Debian werden die alten Kernel nicht deinstalliert. So hat man bei Problemen mit dem neuen Kernel, den “Alten” noch zur Verfügung und kann so das System booten.

Allerdings belegen der Kernel mit seinen Headern eine ganze Menge Platz, so dass man früher oder später etwas aufräumen sollte. Über Synaptic kann man sich die alten Kernel raussuchen und sie dann installieren. Mit ein bisschen Shell-Magie deinstalliert man jedoch mit nur einem Kommando alle alten Kernel inklusive ihren Headern.

Update:

GDM lässt sich auch grafisch konfigurieren, indem man den Erscheinungsbild-Dialog als User gdm ausführt (via @Perry3D):

$ gksudo -u gdm dbus-launch gnome-appearance-properties

Korrekt, der neue Login-Manager ist jetzt eigentlich ein stinknormaler Gtk.Dialog der vom User “gdm” aufgerufen wird. Dieser User hat auch eine gconf-Datenbank in der man auch reinschreiben kann welches Theme benutzt wird.

At the end of this month (October 29th, 2009 to be exact), Ubuntu will be releasing its newest take on the Linux operating system. This time around, it should be obvious (even to the biggest of skeptics) that Ubuntu is making some serious inroads to the business and enterprise scene.

GNU Screen, a windowing system for your console

Powertop is one of those tools every user of Linux on a laptop should have installed – especially if your laptop depends primarily on its battery for life.

Transmageddon is a video transcoder for Linux and Unix systems built using GStreamer. It supports almost any format as its input and can generate a very large host of output files. The goal of the application was to help people to create the files they need to be able to play on their mobile devices and for people not hugely experienced with multimedia to generate a multimedia file without having to resort to command line tools with ungainly syntaxes.

PDF Mod is available as a free source package for Linux systems that's fairly easy to compile; the Lazy Ubuntu blog linked below has a copy-paste terminal guide for Ubuntu users.
