Non-Linux FOSS: All the Bitcoin, None of the Bloat

LinuxJournal - Tue, 2015, May26 - 10:17

I love Bitcoin. Ever since I first discovered it in 2010 and mined thousands of them, I've been hooked on the technology, the concept and even the software.

One of the frustrations with using Bitcoin, however, is that the blockchain has gotten so large. more>>

Dr Hjkl on the Command Line

LinuxJournal - Thu, 2015, May21 - 12:43

The first time I used vi was in a college programming course. It was the default editor on the computer lab's UNIX systems we used to compile our assignments. I remember when our professor first introduced vi and explained that you used the hjkl keys to move your cursor around instead of the arrow keys. more>>

LinuxJournal - Wed, 2015, May20 - 11:17

One of the most crucial pieces of any UNIX-like operating system is the init dæmon process. In Linux, this process is started by the kernel, and it's the first userspace process to spawn and the last one to die during shutdown. more>>

LinuxJournal - Mon, 2015, May18 - 09:29
A new mini-computer is on the way, and it looks like it may be the Raspberry Pi killer we've all been waiting for (sorry Pi). C.H.I.P. is its name, and it looks set to wipe the floor with its established competitor on several counts:

1. It's completely open source. I don't just mean the software, either. more>>

Infinite BusyBox with systemd

LinuxJournal - Tue, 2015, May12 - 05:58

Lightweight virtual containers with PID 1.

In this article, I demonstrate a method to build one Linux system within another using the latest utilities within the systemd suite of management tools. The guest OS container design focuses upon BusyBox and Dropbear for the userspace system utilities, but I also work through methods for running more general application software so the containers are actually useful. more>>

I've touted the awesomeness of Calibre in the past. And although the Web-based calibre2opds still is an awesome way to access your eBook library, using a native Android app is even smoother. more>>

It's Easier to Ask Forgiveness...

LinuxJournal - Thu, 2015, May07 - 07:00

...than to understand Linux permissions! Honestly though, that's not really true. Linux permissions are simple and elegant, and once you understand them, they're easy to work with. Octal notation gets a little funky, but even that makes sense once you understand why it exists.

One ongoing question kernel developers face is the best way to delete data so no one else can recover it. Typically there are simple tools to undelete files that are deleted accidentally, although some filesystems make this easier than others. more>>

Chrome-Colored Parakeets

LinuxJournal - Tue, 2015, May05 - 07:00

I personally like Google's Chrome interface. It's simple, fast, elegant and did I mention fast? Unfortunately, I don't like how locked down the Chrome OS is on a Chromebook, nor do I like its total dependence on Google. I also don't like the lack of ability to install Chrome easily on generic hardware. Thankfully, Budgie is here to help. more>>

LinuxJournal - Mon, 2015, May04 - 10:42

Linux has a well deserved reputation as being one of the most secure platforms for individuals and businesses. This is largely due to the way security is integrated into the system, but there is a great risk in being too complacent. Recent events serve to remind us that there is no such thing as an uncrackable system. more>>
