Linux AIO some of the most common distributions in one ISO

Aug 262014

Sometimes you want to test or show different GNU/Linux distributions, or just different desktop environment, and in these cases you usually have to put different ISO on CD/DVD or better on USB Sticks and this usually take some time. Luckily now there is a new and nice project that makes the work of testing different distributions much more easy: the Linux AIO (All In One) project.

From the Linux AIO website:

Our plan is to bring some of the major Linux distributions (Ubuntu and flavors, Linux Mint (“Debian”), Debian Live) with different desktop environments on one ISO file that can be burnt on one DVD or USB flash drive. Every one of them can be used as Live system, with no need of installation on hard drive or can be eventually installed on computer for full experience.

How to reboot Linux automatically on Kernel Panic

Luckily this problem don’t happen so frequently, at least using stable kernel and distributions, but sometime your beloved Linux could go in “Kernel Panic”.

A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover. The term is largely specific to Unix and Unix-like systems; for Microsoft Windows operating systems the equivalent term is “stop error” (or, colloquially BSOD “Blue Screen of Death”).

The kernel routines that handle panics, known as panic() in AT&T-derived and BSD Unix source code, are generally designed to output an error message to the console, dump an image of kernel memory to disk for post-mortem debugging and then either wait for the system to be manually rebooted, or initiate an automatic reboot.

The default it’s to wait, so if this happen on one of your servers and you don’t notice it all its services could stay down for some time, while using an automatic reboot the problem could be solved quickly.

What’s your upload and download speed at home (or in your office) ?
Are you really sure that you get what do you pay for to your ISP ?

To test the speed of our internet connection There are several internet services such as SpeedTest a web service that is available both from Web browsers and mobile application.

Now you can easily check it also with speedtest_cli a command line interface for testing internet bandwidth using speedtest.net. In this way you can do the test also on servers that don’t have a Browser or a graphical interface. Continue reading »

If, like me, you are a statistics freak you must install this small application on all your computers: WhatPulse

The software tracks a user’s pressed keys, mouse clicks and used bandwidth and the uptime of the system. Periodically, or by hand, the user can upload to the server the number of keystrokes made; this is called “pulsing”.

Users can see where they are in a leaderboard of people who have joined the program and compare themselves against people from their own countries. Users can also join teams, which enables them to compare themselves against people with similar interests (Go Linux Users !!).

There is a basic, and free, version where you can easily see and check all the basic statistics and a premium account where you can see some more stats.

The software is available for Linux, Windows and Mac.

If, like me, you work on terminals connected via ssh to remote computer/server you are probably used to tmux and screen and so it’s not a problem if you have to close your session, as you’ll be able to easily re-connect when you need it, but sometimes you could forget about using one of these utility.

Started a long-running process over ssh, but have to leave and don’t want to interrupt it?
Just start a screen, use reptyr to grab it, and then kill the ssh session and head on home.
