Ceph is a distributed network storage and file system designed to provide excellent performance, reliability, and scalability. Ceph is based on a reliable and scalable distributed object store, with a distributed metadata management cluster layered on top to provide a distributed file system with POSIX semantics. There are a variety of ways to interact with the system:
Distributed file system. An dynamic cluster of metadata servers create and manage and file system hierarchy, providing POSIX file system access via the Ceph file system client in recent Linux kernels or via a FUSE driver.
Object storage. A librados library provides applications direct access to the underlying distributed object store. Clients talk directly with storage nodes to store named blobs of data and attributes, while the cluster transparently handles replication and recovery internally.
S3-compatible storage. A radosgw proxy server provides an S3-compatible REST interface to the distributed object storage system, allowing applications designed to work with Amazon’s S3 service to use a private installation of Ceph instead.
Rados block device (RBD). The RBD driver provides a shared network block device via a Linux kernel block device driver (2.6.37+) or a Qemu/KVM storage driver based on librados. In contrast to alternatives like iSCSI or AoE, RBD images are striped and replicated across the Ceph object storage cluster, providing reliable, scalable, and thinly provisioned access to block storage. RBD supports read-only snapshots with rollback.

24) !!:gs/foo/bar
Runs previous command replacing foo by bar every time that foo appears
Very useful for rerunning a long command changing some arguments globally.
As opposed to ^foo^bar, which only replaces the first occurrence of foo, this one changes every occurrence.

Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP server. It is designed to provide DNS and, optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP/PXE for network booting of diskless machines.
Dnsmasq is targeted at home networks using NAT and connected to the internet via a modem, cable-modem or ADSL connection but would be a good choice for any smallish network (up to 1000 clients is known to work) where low resource use and ease of configuration are important.

Most Linux photographers use graphical applications like digiKam, Rawstudio, or darktable as their tools of choice for processing and managing photos. But it is possible to set up a photographic workflow built around command-line tools that can handle a wide range of photographic tasks: from fetching photos from your camera and convert RAW files to the JPG format, to backing up the photos on a remote machine and even publishing them on the web. Here is a sample workflow you can use as your starting point.

LXC is the userspace control package for Linux Containers, a lightweight virtual system mechanism sometimes described as “chroot on steroids”.


LXC builds up from chroot to implement complete virtual systems, adding resource management and isolation mechanisms to Linux’s existing process management infrastructure.

Linux Containers (lxc) implement:
Resource management via “process control groups” (implemented via the cgroup filesystem)
Resource isolation via new flags to the clone(2) system call (capable of create several types of new namespaces for things like PIDs and network routing)
Several additional isolation mechanisms (such as the “-o newinstance” flag to the devpts filesystem).

The LXC package combines these Linux kernel mechanisms to provide a userspace container object, a lightweight virtual system with full resource isolation and resource control for an application or a system.

Give it a try: Most distros come with screen, and those that don't have it in their repo: Lookup gnu screen if you need to. Otherwise, from any command-line, just type "screen"

If you get a welcome message, just return until it goes away. You'll now have what looks like a normal command line.

So type "ls" and enter, and you'll get a list of files. Now (where it gets clever) Ctrl-A Ctrl-C and suddenly your screen goes back to the way it was before you ran the 'ls' command.

But press Ctrl-A twice, and your 'ls' command and output is back! Ctrl-A twice again, and it goes away.

This is because you have TWO command-lines running, and only one of them has had 'ls' run in it.

And the price is this: If you show a Windows user a standard Gnome Ubuntu desktop, what exactly do they see that makes them interested in learning about this new & different OS?

Very little.

Taskbars, buttons, menus.. nothing they're not used to. An office suite and a few web browsers. Yawn. A rotating cube.. well, that IS different, but what's it good for? Nothing but eye candy.

It is very hard to get somebody interested in Linux when you show them Gnome or KDE. Because they've done such a good job of catching up with Windows, they're so close now that they're boring.

The funny thing is, now, that showing somebody the GUIs that were kicked off by the initiative to compete with Windows and get away from the arcane command-line.. it doesn't work. It just doesn't look interesting.

And yet if you then shrug and switch back to your normal stripped-down window manager.. suddenly that interest is aroused. They see a desktop like this one:


and suddenly they're fascinated. Where's the taskbar? The desktop icons? What's all that text doing? It looks like an OS out of the Matrix!

In singleplayer mode, the player takes over the role of the young woman Rain and follows her through her life. The story is divided into several missions and animated cutscenes.

The game also features an extensive multiplayer mode, firstly allowing players to accomplish singleplayer missions with the help of others and secondly to compete against other players in numerous team-based modes.

Being developed on the *awesome* XreaL engine, 'Rain' has an excellent base to built upon.

Pushover is a fun puzzle game originally published by Ocean in 1992. In this game you control an ant that can walk along platforms that are connected with ladders. On those platforms are dominos that need to fall according to some rules.
All dominos must fall and none must crash into another
One special domino must fall as last domino and that domino triggers the exit door to open when you enter the exit door the level has been completed
You may rearrange as many dominos as you want, except for the trigger. You may not place dominos in front of the doors, except for the vanishing domino.
You may push push once to start a chain reaction with the dominos leading to the fall of all of them
All this has to be done within a time limit (which is normally generous)
There are 11 different dominos that behave differently when pushed, some fall, some not, some wait a bit before they fall, some raise, some toppler until they meet an obstacle
There is a help in the game and introductory levels that show how all the dominos work
What you find on this web page is a faithful reimplementation of the original game. Although we removed the original password scheme as it will not work on an open source game.

FreeLords is a turn-based strategy game in the style of the classical Warlords. In short, you produce armies in cities and use them to conquer more cities and finally defeat the other players. We have already extended the game design at some points, e.g. by introducing hitpoints for the armies or using simultaneous moves.

The game was started in 2000 by Michael Bartl using C++ and Qt. In 2007, we decided to do a Java port due to several serious restrictions (dependencies for example were a real pain).
