Installing MySQLdb on MacOS Lion

jon — Thu, 10 Nov 2011 06:58:01 +0000

I ran into an issue installing the MySQLdb module.

>>> import MySQLdb
/Library/Python/2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.7-intel.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /Library/Python/2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.7-intel.egg/_mysql.pyc, but /Users/jhaddad/Downloads/MySQL-python-1.2.3 is being added to sys.path

Referenced from: /var/root/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.7-intel.egg-tmp/_mysql.so
Reason: image not found

I fixed it by doing the following:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql

I’m not sure if it matters, but I’ve got MySQL 5.5 installed.

Found the answer here – but it wasn’t the top voted one. If this is useful, vote Chris up.

Api Tester now hosted on Github

jon — Thu, 06 Oct 2011 02:27:41 +0000

About 4 years ago I decided to write a little GUI tool for manually testing API calls. Put it on the top of my blog, people have downloaded it, and I haven’t touched it since then. Last updated timestamp was 2007.

I don’t know if anyone wants it, but it could be useful as a starting point, or to understand how Cocoa apps were written… 4 years ago… I don’t know. Whatever.

Headless Virtual Box

jon — Thu, 15 Jul 2010 23:07:01 +0000

I like running VirtualBox headless on my Mac. It doesn’t show up in the Dock, and feels like it’s a remote server.

First, figure out which VMs you have on your machine.

haddad-work:~ jhaddad$ VBoxManage list vms
Oracle VM VirtualBox Command Line Management Interface Version 3.2.6
(C) 2005-2010 Oracle Corporation
All rights reserved.

"WebServer" {2c61a180-e098-4926-b09a-27e431791c88}

Then start it using VBoxHeadless

nohup VBoxHeadless -s WebServer -vrdp on  &

I’m using Cord for RDP.

Open up Cord. If you’re using the default settings, you can just go to quick connect and type “localhost”. You’ll see your VM booting.

Mount afp share over command line

This is so useful to me that I have to repost it here, just in case it disappears.

# create a folder for the mount point
sudo mkdir /Volumes/music

# mount the disk
mount -t afp afp:/// /Volumes/music/

#refresh the finder for when you get back
disktool -r

# when you're done
sudo umount /Volumes/music

Running Puppet Master on Mac OS X Snow Leopard

jon — Tue, 02 Feb 2010 20:24:39 +0000

As of a few hours after this post, I’ve given up trying to get Puppet Master running on Snow Leopard. There appears to be an issue with the SSL certificates generated that’s preventing puppetd from getting it’s recipes. There doesn’t appear to be any way to disable this. I have switched to a CentOS VM, which worked perfectly the first time. The Unixy underpinnings of my Mac seem to be getting less and less useful every day.

I kept getting the below error when trying to start puppet, even though I had created the user and group through the accounts prefs pane. Apparently that’s not good enough for the PuppetMaster to run.

For some reason this figuring this out was a huge pain. These are the steps I took to getting it installed. If it looks simple, well, that’s because it really is. Most people suggest solving this with MacPorts, but then I still wouldn’t know how to set up users and groups on Snow Leopard, so I’d just be screwing myself over in the long run.

Anyways, here’s the error I was getting:

err: /File[/var/puppet/rrd]: Failed to retrieve current state of resource:
Could not find group puppet

How to solve:

Install Facter and Puppet

This is easy enough – Snow Leopard comes with Ruby by default. Both can be downloaded from the Reductive Labs download page.

Install Server Admin Tools.

As of this blog entry, you can find them in Apple’s downloads section, although it was kind of a pain to find.

Enable Remote Management for youself

I was not able to connect to localhost until I enabled this option. You can control which users have management rights, so I’m not to concerned here.

Create user and group for puppet.

Use the GUI tool to create new a puppet user and group. You should now be able to start the pupptermasterd (yay!)

I’ll expand this post if I realize I forgot anything, or if questions come in.

Installing NumPy on MacOS X Snow Leopard

jon — Tue, 22 Sep 2009 19:24:08 +0000

NumPy is a requirement to work with PyTables. This is the second step in the install process, after getting HDF5 set up.

These instructions are based on the ones found on the NumPy site, but I’m summarizing things for my own use later on.

First, you’ll need to install the Fortran compiler for OSX (gFortran). Fortunately there’s a Fortran universal binary installer.

Next, get the NumPy source. You can find it on Sourceforge.

Now, build with gFortran.

python setup.py build –fcompiler=gnu95
python setup.py install

Enjoy!

Helpful guide for setting up SSHFS on mac

jon — Wed, 09 Sep 2009 23:23:26 +0000

I finally got fed up enough to look into this. I’ve previously used Samba mounts, but this in theory should be better.

http://www.turingtarpit.com/2009/04/mounting-remote-filesystems-on-osx-leopard-using-sshfs-macfuse-and-macfusion/

If you’re using Snow Leopard, the drive will not be able to mount. You can get around this by deleting /Applications/Macfusion.app/Contents/PlugIns/sshfs.mfplugin/Contents/Resources/sshnodelay.so

OS X: Spaces + Fluid = Awesome

jon — Sat, 29 Nov 2008 22:41:17 +0000

I’ve tried so many times to use Spaces, and I keep failing. As useful as it *should* be, it just never was. And I’ve finally realized why. Most of what I do is in a web browser. And spaces just wasn’t made for that. I want Gmail to always be in space 3. Facebook on 4. It just wasn’t meant for that.

I’ve recently discovered Fluid. Fluid brings creates Site Specific Browsers. This means I have an actual application that I launch called Gmail. It’s independent from everything else, doesn’t crash when Safari does (which, to be honest, is all the time). I can assign it to a space. So good.

Also, I’ve discovered hitting F9 (expose) after triggering F8 for spaces, it’ll do expose over all the spaces. Pretty cool way to organize.
