Linux: How to share files on a local network with woof
We’ve all been in this situation were we want to exchange files with other users connected to the same network as we are, and while there are tons of ways to do this, almost none of them is easy, quick, or simple enough. Thankfully, though, Linux users can utilize a small tool called “woof” that simplifies the process and makes the exchanging of files a walk in the park. What I am about to present in this short tutorial is suitable for home networks where convenience is the primary concern, and security isn’t an issue.

Check Internet Speed with speedtest-cli on Ubuntu

Check Internet Speed with speedtest-cli on Ubuntu
Internet connection speed is something that we always check at our homes and offices. The most common method that we use is by visiting a speed test website like speedtest.net. On that site, a javascript application is loaded in the web browser which selects the best (nearby) server based on the ping time and then the speed test results for that server are shown. Speedtest.net also uses a flash player to produce the result graphically.

The problem using these web based speed tests is that it does not allow you to schedule the speed test at regular intervals, e.g. as a cronjob and you can’t use them on headless servers. One application that can solve this problem is “speedtest-cli”. This application allows you to check your internet speed using the command line.

An introduction to Linux activity/event trackers

An introduction to Linux activity/event trackers
Most modern GNU/Linux distributions use some kind of a software service that tracks the user activities and events. These events can be anything, from the opening of a document file, to the chat conversation. This isn’t happening for the purpose to monitor the user and sell this usage data information to 3rd parties, but to help users enjoy a more user-friendly and unified experience across their applications. For example, if you want to quickly locate that document that you opened last weekend, chances are that you will easily and promptly find it after opening your file manager and going to the “Recent” folder.

How to setup virtual containers with LXC and quota support on Debian 8
Quota support is an often requested feature in lxc. Linux filesystem quota is required when you want to give multiple users access to a container and want to control that one user is not using all the disk space. Quota is also required for web hosting servers, e.g. with ISPConfig 3, for the same reason: one website shall not be able to fill up the whole disk. This howto shows you, how you can use lxc with hard disk quota using qemu nbd with a qcow image file on Debian 8.
