Famous Sed One-Liners Explained, Part I: File Spacing, Numbering and Text Conversion and Substitution Inspired by the success of my "Awk One-Liners Explained" article (30,000 views in first three days), I decided to explain the famous sed one-liners as well. These one-liners, just like the Awk one-liners, are compiled by Eric Pement. You may download them here: sed one-liners (link to .txt file). Most people are only familiar with one particular command of sed, namely the "s" (substitute) comand. s/comand/command/. That is unsatisfactory.

Setting up Vagrant with Laravel 4 One of the things that annoys me the most about picking up someone else’s work is that it shouldn’t be difficult to get up and running. If I start exploring an Open Source project, I want to see something magical happen almost instantly or I lose interest. It’s just not worth the time to have to jump through hoops and set everything up just to see a working example. Not having a standard environment for a project can also be a problem when you are working as part of a team of developers. If you are all using your own machines, and you all have different versions of each bit of the stack, then you can hit problems where code is written for one machine, but causes problems on another. You don’t want to be in a situation where your code passes all the tests locally, but constantly falls over as soon as it hits the production server.

Some useful shell scripts Some shell scripts to make life easier Over the years I accumulated way too many aliases, so I started converting most of them to shell scripts. This has the added advantage that they can be made much more powerful, with enhancements impossible in aliases. Here are some of the most useful, that can easily be customized to anyone's unix environment. HTG Explains: The Linux Directory Structure Explained If you’re coming from Windows, the Linux file system structure can seem particularly alien. The C:\ drive and drive letters are gone, replaced by a / and cryptic-sounding directories, most of which have three letter names. The Filesystem Hierarchy Standard (FHS) defines the structure of file systems on Linux and other UNIX-like operating systems. However, Linux file systems also contain some directories that aren’t yet defined by the standard.
SSH Can Do That? Productivity Tips for Working with Remote Servers SSH has many features which are helpful when working regularly with files on remote servers; together they can give a vast increase in productivity over the bare use of SSH. If you regularly use SSH, it’s worth spending a little time learning about these and configuring your environment to make your life easier. This has been presented at presented at Yapc Europe 2011 in Riga and the Floss UK Spring 2012 Conference in Edinburgh.
PHP: a fractal of bad design - fuzzy notepad (This article has been translated into Spanish (PDF, with some additions) by Jorge Amado Soria Ramirez — thanks!) Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about.

DragonFly BSD Please keep in mind that major modifications have been made to nearly the entire DragonFly kernel relative to the original FreeBSD-4.x fork. Significant changes have been made to every kernel subsystem, as a consequence this list is constrained to the largest, most user-visible changes unique to DragonFly. The scheduler abstraction has been split up into two layers. The LWKT (Light Weight Kernel Thread) scheduler is used by the kernel to schedule all executable entities.
