Dstat is a versatile replacement for vmstat, iostat, netstat and ifstat. Dstat overcomes some of their limitations and adds some extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources in real-time, you can eg. compare disk utilization in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).

Dstat gives you detailed selective information in columns and clearly indicates in what magnitude and unit the output is displayed. Less confusion, less mistakes. And most importantly, it makes it very easy to write plugins to collect your own counters and extend in ways you never expected.

Dstat’s output by default is designed for being interpreted by humans in real-time, however you can export details to CSV output to a file to be imported later into Gnumeric or Excel to generate graphs.

For what I know there isn’t an official google drive application for Linux and so after looking around I’ve found that there are some interesting project that you can use to access your data on Google Drive from your linux, and in particular today I’d like to show 2 of them:

Grive and Grive Tools: These 2 tools are good if you want to use Google Drive on your laptot or Desktop or in general in a graphical environment.

google-drive-ocamlfuse: This is more suited if you want to mount your Google Drive from a server or from a terminal, in fact this software will mount your Google Drive as File System and you’ll be able to move inside it and see all your files, like a local file system.

Your server appearing pretty slow could be many things from wrong configs, scripts and dodgy hardware – but sometimes it could be because someone is flooding your server with traffic known as DoS ( Denial of Service ) or DDoS ( Distributed Denial of Service ).

Denial-of-service attack (DoS attack) or Distributed Denial-of-service attack (DDoS attack) is an attempt to make a machine or network resource unavailable to its intended users. This attack generally target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers. DoS attacks are implemented by either forcing the targeted computer to reset, or consuming its resources so that it can no longer provide its services or obstructs the communication media between the users and the victim so that they can no longer communicate adequately.

In this small article you’ll see how to check if your server is under attack from the Linux Terminal with the netstat command

YrminsulHave you had enough of nice and friendly heroes? Then become the villain of the piece! Get your own back on the pathetic forces of the good and make them finally understand that evil is something to be taken seriously, and must be well done. Resist their combined attacks during a game combining strategy and Tower Defense phases in a persistent universe. Make their islands, which make up this boring haven of peace, fall one by one. Evil spirits, boastfulness and a tendency towards machievelic laughter will finally be rewarded through a title which renews the codes of the genre. You can find all of this and a great cartoon style graphics in this new title (it’s been released on 16 of April for Linux): Yrminsul, the game has been developed by an French Indie software house: Studio Black Flag Let’s see some more about this game.

novena

The team that is building the Novena project is launching a crowdfunding campaign around the Novena open hardware computing platform. Originally, this started as a hobby project but by popular demand, they have prepared a crowdfunding offering and so everyone can contribute to the interesting project and bring at his home this interesting computer.

Novena is a 1.2GHz, Freescale quad-core ARM architecture computer closely coupled with a Xilinx FPGA. It’s designed for users who care about open source, and/or want to modify and extend their hardware: all the documentation for the PCBs is open and free to download, the entire OS is buildable from source, and it comes with a variety of features that facilitate rapid prototyping.
