Link: How to convert Apache rewrites for nginx

Apache is still by far the most widely deployed HTTP server, according to the latest Netcraft web server survey, but nginx has been slowly, steadily gaining market share, thanks to its blazing speed. If you want to try a faster web server and move from Apache to nginx, you’ll probably have to change some of your websites’ configurations, starting with rewrite directives. To migrate rewrite rules from Apache to nginx, start with these tips and tricks.

Link: How to clean up disk space on Linux

BleachBit is an open-source disk space cleaner software, available on Linux and Windows platforms. Besides cleaning up disk space, BleachBit can also shred files securely, and wipe out unallocated disk space for your privacy.

In this tutorial, I will describe how to clean up disk space on Linux by using BleachBit.

Article series: CommandLineFu, BASH, AWK, Perl, SED One-Liners Explained

We must confess that we are not as fond of the Linux command line as some Linux users — we’ll take a good GUI, and a mouse over a keyboard any time we can. But for those that love working at the Linux command prompt (and that probably don’t make nearly as many typos as we do), we thought you might appreciate this series from the catonmat blog:

Or perhaps you’d prefer this series:

Link: How to Flash an SD Card for Raspberry Pi

The Raspberry Pi is an incredible little computer made up of a components and connectors on an unfeasibly small printed circuit board that is approximately the dimensions of a credit card. Depending upon your intended use, your Rasberry Pi may have a keyboard, monitor and mouse added. Regardless of your intended use, you are going to need an SD (Secure Digital) card on which to install an operating system.

This tutorial describes how to install an operating system onto an SD card for use in your Raspberry Pi.

If you’ve ever turned a Raspberry Pi into a media center or retro gaming station, you know how frustrating it can be when it crashes and corrupts your SD card. Here’s a little trick to making that a little less painful.

Link: Autotrash – Purges files from your trash based on age and/or filename

Autotrash is a simple Python script which will purge files from your trash based on their age or the amount of free space left on the device. Using autotrash -d 30 will delete files which have been in the trash for more then 30 days. It uses the FreeDesktop.org Trash Info files included in the new GNOME system to find the correct files and the dates they where deleted.

Features:
Remove files that are older then a given number of days (see the -d option)
Purge older files to ensure a specific amount of disk space is free (see the –min-free option)
Check for remaining disk space, and only delete if you are running out (see the –max-free option)
Delete regex matching files first (see –delete-frist option)

Link: A Raspberry Pi File and Print Server

I was recently looking into the options to buy a living room “home server” to centralize certain services like file and print server, media server, etc.

It didn’t take me long to realize that for less money I could get a whole legion of small microcomputers that do the same work better and more securely; and use less energy while doing so.

This was of course the pretext to buy my first Raspberry Pi. A few more should follow… This article starts a little series explaining what I did and how I did it. Today, I will look at the first and simplest type of server …

Link: Raspberry Pi – Driving a Relay using GPIO

There’s something exciting about crossing the boundary between the abstract world of software and the physical ‘real world’, and a relay driven from a GPIO pin seemed like a good example of this. Although a simple project, I still learned some new things about the Raspberry Pi while doing it.

Avoid Bluestacks until they fix their nasty bug!

This started out as a simple link to an installation tutorial that we found:

Now days Android is leading mobile operating system , there are wide range of app and games in android , If you are really fond of using android applications but unfortunately you don’t have any android supported Phone. Then don’t worry you can still enjoy all the Android application and Games on your PC and Laptop, One software will helps you to make your dream come true. Now days Bluestacks is one of the famous and working Software Which convert any android apps in Windows or Mac version. By using Bluestacks software you can run easily any android app on your pc or laptop.

In addition to the Windows versions, there is also a Mac version of the Bluestacks software, and that’s what we tried. But as soon as you install it and attempt to run it, to comes up with an error message that reads:

“Network Issue. The network is experiencing some problem. Please retry or cancel.”

If you put this error into Google, you find that many other potential users, using both the Windows and Mac versions of this software, have run into this issue. And when one user attempted to get help, what did the company do? They addressed a completely different issue and then marked the thread as “answered”, basically washing their hands of the issue.

Well, this bug still exists, and it stops you cold after you have installed the software. So for now, Bluestacks earns our “avoid this software package” designation. Don’t waste a minute of your life trying to install and run this thing, because several users with more experience than us have apparently tried and failed. But if you ignore our advice and somehow manage to get it working, please leave a comment telling us how you did it!

EDIT: In the meantime, here’s another way to run Android on your PC or Mac, though we haven’t actually tried this one yet:

Link: OctoPi – 3D Printer Web Server Distribution for the Raspberry Pi

I am happy to say that I am a backer of the Rigidbot 3D printer, (which you can pre-order already), I am expecting it to arrive in August. In the meantime, I have ordered a Raspberry Pi to play with and started visiting a local maker community known as XLN.

This led me to find a really cool project called OctoPrint, which lets you control 3D printers using a Raspberry Pi over a web interface, however people were not installing it on their Pis because there was no out-of-the-box solution. Today I am happy to announce that a solution is here! I give you Octoprint + Rapberry Pi = OctoPi. A raspberry Pi distribution which runs OctoPrint out of the box, with support for time-lapse video on webcams (there is also an experiential version in the works that supports streaming from a raspberry Pi camera).
