- Fixing scrolling, hidden scrollbars etc in Mountain Lion
- Here's some other useful tips for Mountain Lion
- X11 isn't supported, so if you run X11 / GTK apps like Mandelbulber use XQuartz
- Quicksilver stopped working after the upgrade so I switched to Alfred (thanks to Ashe Dryden for the recommendation)
- I used Spaces heavily on Snow Leopard (6 desktops, with apps assigned to workspaces for music, code, social media, graphics, sysadmin and writing), which became useless with 10.7 (one of the biggest reasons I didn't upgrade when 10.7 came out). I'm using TotalSpaces to restore classic Spaces functionality. I'll probably end up paying the $18 for the full version (almost as much as the OS upgrade itself) just because Spaces is so essential to how I work.
- Getting the battery time remaining to show in the menu bar was a chore. In Mountain Lion, you can no longer see the battery time next to the battery icon. There are 2 apps that can fix this for you. One is a simple one called "Battery Time" the other a more-advanced $1 app called "Battery Time Remaining".
- Since 3rd-party menubar items cannot be re-arranged (come on already) I couldn't actually see the battery time remaining on my laptop since the icon was pushed all the way off to the side. There are a few apps that you can get to fix this for you. "Bartender" at a pricey $15 or the more reasonably-priced "Menu Bar Rearranger" at $4.99. But really, why do I have to pay to do something as basic as change the ordering of some icons on my menu?

Drink-by date: This post was written based based on work I did in June, 2013. The GHC, Haskell, Cabal and pandoc were all current versions installed in Ubuntu 10.04. If you're reading this documentation after June, 2015, consider it out of date.
This blog post was the original inspiration to use Pandoc)
A few months ago I started putting my resumé on Github. As a freelance software dev it's quicker to send somebody to 1 spot to see both code for projects I work on and descriptive, bulleted-list of accomplishments (without all of the monetization noise of LinkedIn). Recently I spent 5 hours on one of those endlessly-recursive campaigns of compiling things from source code in order to save myself a few minutes of maintaining my online resumé in different formats (pdf and markdown) and since it deals with some bugs in some standard Ubuntu / Debian packages, I'll post instructions here for how I fixed them.
My goal was to be able to update my resumé in markdown, and have run a single deploy script that would commit changes, generate a pdf from the markdown and push the updated markdown and pdf to GitHub. There's a Linux utility called "pandoc" that does this and a whole lot more. It's written in Haskell, a powerful functional programming language that is beloved by academics and high-frequency stock traders and otherwise hasn't broken into mainstream software developement.
My first time around, I did a standard "sudo apt-get install pandoc" on my Ubuntu server and thought I was good to go. The syntax for a basic conversin is simple, and like ffmpeg, the input and output formats are inferred by file extension:
$ pandoc resume.md -o resume.pdf
Except that this yielded the following error:
pandoc: resume.md: hGetContents: invalid argument (Invalid or incomplete multibyte or wide character)
A character-encoding bug. Removing curly quotes from the markdown file confirmed this since it worked fine if the input document was all ascii. But what's the point of a PDF if you have to limit yourself to ugly straight quotes and spelling "resumé" as "resume"? There was some chatter on google groups that this was an issue with setting the right LANG in your locale, but that in later version of pandoc this bug was fixed. Rather than fiddle with global settings, I opted to upgrade pandoc.
The version of pandoc, as well as Haskell and GHC (the Glasgow Haskell Compiler) are all years out of date in debian / ubuntu. (The computer I was working on was running Lucid 10.04 which is supported through 2015). So geting the latest pandoc woudln't be as simple as an apt-get upgrade, and would require upgrading the GHC, Haskell, the Haskell Package Manager (cabal) and finally pandoc. All of these are source-code installs except for the final upgrade of pandoc.
If you've already tried to install pandoc or Haskell via apt-get you'll need to remove the packages via the following command:
$ sudo apt-get autoremove ghc6
Now we're ready to start the installation process. First, install the dependencies via apt-get:
$ sudo apt-get install libgmp3c2 freeglut3 libedit2 libedit-dev freeglut3-dev libglu1-mesa-devpandoc uses LaTeX for formatting, so you'll need to get pdflatex on your system.
$ sudo apt-get install texlive-full
Now you'll want to get the source code to build the GHC and the Haskell Platform. First the GHC. This a standard configure / make install build.
Cabal, the Haskell Package manager, is included in the Haskell Platform
$ wget http://lambda.haskell.org/platform/download/2013.2.0.0/haskell-platform-2013.2.0.0.tar.gz $ gunzip haskell-platform-2013.2.0.0.tar.gz $ tar -xvvf haskell-platform-2013.2.0.0.tar $ cd haskell-platform-2013.2.0.0 $ ./configure $ ./make $ ./sudo make install
You can also get the source for Cabal from GitHub.
Once you have Cabal up and running, first refresh the packages list:
$ cabal updateNow, you can install pandoc
$ cabal install pandocCabal will install a bunch of dependencies. This will tak a few minutes. Cabal installs executables to ~/.cabal/bin/pandoc - you can symlink this to a directory that's already in your path:
sudo ln -s ~/.cabal/bin/pandoc /usr/local/bin/pandoc
Now you should be ready to go. For some pointers as to how I actually automated the generating of pdf's by committing changes to my resumé, check out this shell script: https://github.com/erstwhile/resume/blob/master/deploy
