The inner workings of MacOS.

Mac OS & Python: Add and remove Python modules

Mac OS has Python built-in, and also has the cool command ‘easy_install’ already part of the system. This command lets us easily grab and install Python modules and their dependencies. However, this tool does not allow us to uninstall them. For that we’ll need to get another command – one that we can get using the easy_install command.

First we’re going to install pip on our system, a command that will help us cleanly uninstall Python code when we need to. Open up your terminal and type: Continue reading Mac OS & Python: Add and remove Python modules

Mac OS & Python: An Introduction for the Applescripter

Applescript is a great tool for us Mac users. It’s a scripting language that’s easy and simple enough to not scare away true beginners. A fun feature of Applescript is how to write code, since almost looks like regular English sentences. Applescript was the first scripting language I felt comfortable using. However, its ceiling of limits is pretty low. For some tasks it’s better to turn to other tools.

When jumping from the Applescript ship to Python, the water seems mighty cold. There is a lot more ‘computer code’ and all the commands are new and foreign. Plus, the language’s name is a type of snake! You’ll be feeling homesick for the ease of Applescript, but these feelings will pass.

Python’s developers wanted to create a language that was fun to learn and use, that’s why they named it after the British comedic troupe, Monty Python. And when compared to other languages, like C and Pearl, it is easy to pickup and learn. Continue reading Mac OS & Python: An Introduction for the Applescripter

Easily Compressing Multiple Folders

You have a directory full of important folders, and you want each one compressed separately. Doing this by hand would take waaay to much time. Of course, we can do this in terminal, and with one line of code (sweet!) so it’s easy to use.

For this we use the “Find” command built in into our computer. From there we’ll have two choices, to use compress it to a zip file for a dmg file.

Snazzy Peer-to-Peer In Your Browser

I am really impressed with this little piece of software made by Patrick Williams over at bittorrent.

Paddleover allows you to share your files with anyone in the world using the power of torrents, but is simple enough for even the most basic of users to understand.


In this image you can see me, and the user “Patrick” sharing files with each other. I currently have none shared, but Patrick has four. I can browse those files, and choice to download them if I want. To grab a file, I just click and drag it over to my name, and it is automatically added to my download folder on my computer. Pretty snazzy!

This circle view can be expanded into sharing multiple files with multiple people, each with their own folder select shared content. Each computer is now like a remote hard disk, but using a torrent backend to transmit the data. I would like to see this simple method applied to content distribution of digital products, like videos and games.

Mac OS: Zipping with your terminal

The basic command structure for compressing a file into the zip format with the terminal is:

zip -r <destination> <source>

If you want to compress more than one folder or item:

zip -r <destination> <source1> <source2>...

The source can be a file or folder.

Unfortunately zip is not very smart when it comes to folders and it will save not only the file, but the path to the file as well. We can fix this behavior by adding just a little bit to the original command.

Mac OS: Command basics – “cd” and “ls”

For those out there that are new to using Terminal, or need a quick review, this is a quick overview of the “cd” and “ls” commands. These two commands are the basic tools for navigating the file structure “inside” of your Mac. Once these two are mastered, you will be able to comfortably move onto doing cooler, more complicated commands that can be run in Terminal. Continue reading Mac OS: Command basics – “cd” and “ls”

Fixing Adobe Applescript Errors

Fixing Adobe Applescript Errors

If you are still using an Adobe Photoshop CS3 or CS4, you might have run into some funky Applescript errors. These errors sometimes pop-up as, “Error loading /Library/ScriptingAdditions/Adobe Unit Types.osax”, or “Can’t make 720 into type traditional points”, or something similar.

The fix for this is easy, and is provided straight from Adobe. The error comes from a conflict between the old 32-bit component and the newer 64-bit scripting environment of Mac OS X 10.6+ (Snow Leapard, Lion, and Mountain Lion).

There are three ways to fix the issue, but simplest is to download the updated file and install it into the “/Library/ScriptingAdditions” folder of your Mac, then restart your computer.

Setting Pidgin and Google Talk (GTalk) with A Custom Domain

Pidgin IM LogoPidgin does a great job of connecting all the chat & IM protocols together, and is available on Windows, Mac, and Linux (yeah!), plus it’s open-source and free! Its interface is dead-simple, but sometimes its setup can be confusing for beginners.

If you have a custom email domain for your gmail account, setting up to use Google Talk through Pidgin needs a couple extra tweaks to the settings. Follow these easy steps to get started.

Mac OS: Making an ISO Image

Many people don’t know that Macs can native make an ISO disk backup without any third-party software – part of the Unix backbone of the operating system. This built-in tool allows anyone to save disc data quickly and reliably. I have included the instructions needed to make a perfect copy of any disc – simple and easy.

Mac OS: Tweeting using cURL

Termianl-IconThe cURL function, found on most UNIX based systems, including the Mac OS, is one of the cooler functions that is also simple to use and awesomely powerful when used correctly. Check out my introduction to CURL for more information about some cool things you can do with it.

Recently I found out that it is simple and relatively easy to post new status updates to twitter through the Terminal using cURL. This opens up the doors for using Applescript, BASH or other languages to automate postings if needed.
