How to Limit the Network Bandwidth Used by Applications in a Linux System with Trickle

Trickle is a network bandwidth shaper tool that allows us to manage the upload and download speeds of applications in order to prevent any single one of them to hog all (or most) of the available bandwidth. In few words, trickle lets you control the network traffic rate on a per-application basis, as opposed to per-user control, which is the classic example of bandwidth shaping in a client-server environment, and is probably the setup we are more familiar with.

Understanding Linux CPU stats

Let's take a step back. There are 3 general states your CPU can be in:

Idle, which means it has nothing to do.
Running a user space program, like a command shell, an email server, or a compiler.
Running the kernel, servicing interrupts or managing resources.
These three meta states can be further subdivided. For example, user space programs can be categorized as those running under their initial priority level or those running with a nice priority. Niceness is a way to tweak the priority level of a process so that it runs less frequently. The niceness level ranges from -20 (most favorable scheduling) to 19 (least favorable). Read More

Linux mini-drones jump, flip, climb, and fly

Parrot is prepping two Linux-based mini-drones: a $160 “Jumping Sumo” wheeled robot and a $100 “Rolling Spider” quadrocopter that can fly, roll, or climb.

Parrot, which last month announced a Bebop successor to its popular AR.Drone 2.0 quadrocopter, has released new information on two smaller, cheaper mini-drones that were originally unveiled back at CES in January. The Jumping Sumo and Rolling Spider will launch in August for $160 and $100, respectively. Read More

Red Hat Releases Enterprise Linux 7

Is Android too open for Google to retain control?

I don't see what the problem is with forking Android. If it's truly an open project then tough bungies for Google if it gets forked. If Google had truly wanted to prevent that and retain total control then they should never have made Android open in any way whatsoever.

However, Google wanted to stop Apple from dominating the mobile device market so they came up with Android and made it an open project. We can debate just how open it really is (certainly not as much as Firefox OS or Ubuntu), but the fundamental truth is that Android isn't iOS or Windows. It is forkable, though not necessarily in an easy way. Read More

Has Linux Conquered the Cloud?

Linux on the desktop may have missed its adoption time line, but Linux in the cloud is a win-win proposition for the post-PC movement.

Linux shows signs that it is the go-to cloud platform. Microsoft's Azure may be the only real threat to Linux cloud dominance -- all other major cloud software platforms are based on Linux and open source software. Read More
