Learning the Command Line – Editing files

Terminal — nano — test1-1

In this session we are going to learn one way of editing text files in Terminal. Back in the day there was pico. This was the editor part of the Pine mail program used in *nix. It was a very simple plain text editor used to create mail and text files. There are other editors such as vi, vim and emacs but those can get complicated and very powerful; these aren’t really needed to create or edit a simple text file. Fast forward to today, we now have nano, the …

If you’ve been keeping up with this series, you’ll know I’ve promised you a little magic. This is it and you might learn a little something too. It’s really simple but …

Learning the Command Line – Shell Scripts

Terminal commands are great but what if you want to have something done every time you login? What if you need to do something on several files or some other repetitive action and don’t want to type in the commands every time. That could get time consuming and dreary. In this article, we will set up our Terminal environment to make certain things a little easier and get a start on shell scripting. A shell script is a text file with all the commands you want run, one after another. …

These Permissions Are Not The Repairs You’re Looking For – A Critical Look at Permissions in OS X

Screenshot 2013-11-29 11.14.32

So, your Mac is acting up. Indeed, a Mac is no more impervious to Murphy’s Law than a non-Mac PC (I use PC here in the literal sense to signify personal computer). What do you do when the inevitable occurs? The first response for many to this will differ – some will seek out a solution, some will be adept enough to tackle the problem head on, some will likely do some sort of voodoo dance (if life has taught me anything, it’s that if you can imagine it, someone …

Mac-Forums Investigates MacKeeper

MacKeeper Default View

Update (July 27, 2013): Grammar/spelling errors corrected and a short section about Mac-Forums’ relationship to the product was added. Introduction One of the persistent questions around the forum has to do with a piece of software called MacKeeper. A cursory scan of the forum will paint in the minds of new members a confusing picture. On the one hand, many of our community members argue against it, describing it as bad, harmful, problematic and, my favourite, akin to snake oil (thanks to chscag for that one). On the other, the software is a permanent …

Clamshell Mode Performance Issues: A Myth?

info_chart

Background A while back, I remember hearing a theory floating around that running a Mac in clamshell mode forced OS X to throttle the processor to save on heat. There is a tiny bit of anecdotal evidence to support such a claim (here) which ultimately suggests that something about clamshell mode might be slowing down the performance of the machine. As someone who runs his machine in clamshell mode quite frequently (the compulsive neat freak in me loves that it saves me space on my desk), I decided to put this …

iOS and The State of Innovation

The first version of iOS (nee iPhone OS).

Quite a few people have been commenting on an ostensible lack of innovation on the part of Apple when it comes to iOS. Search the word “stale” in relation to iOS and you’ll find yourself with enough content for a leisurely Saturday afternoon. Is this critique warranted in light of the mobile landscape that iOS competes in? Preface and a Confession Before I begin this conversation, let me put this out there – I use iOS but I use multiple Android devices and I tend to prefer Google’s Linux based …

The Mysterious File:/// Bug

Recently, there has been a rather silent but important story floating around about an odd bug built into Cocoa (OS X’s application programming interface that, in part, includes the user interface elements of OS X including things like buttons and text boxes). Although not generating a lot of news, this is an interesting bug that’s worth exploring. Triggering the Bug The bug manifests itself simply by typing File:/// into any native Cocoa widget. Open up any application that uses Cocoa for its text boxes and enter that string. Press space …
