sudo port install enchant # you'll need MacPorts 1.8.* for this


Then download the dictionaries from the OpenOffice wiki.

Next, place the files in ~/.enchant like so:

$ tree .enchant/
.enchant/
`-- myspell
    |-- en_US.aff
    `-- en_US.dic

UPDATE
You can also set the path to where you want to keep the dictionaries when you compile enchant by passing the --with-myspell-dir option to configure (or aspell, hspell etc).

What you need to do is open up your vmx file and comment out (disable) the following line:

scsi0:0.mode = "independent-persistent"

Others have also reported finding the following line in their vmx file:

for f in `find . -regex ''.*cp.*snippets''` ; do cp bbb.html $f/ ; done

Which returned:

cp: cannot stat `bbb.html': No such file or directory

bbb.html is a symlink and the default behavior of cp (I think) is to try and copy the actual file, which didn’t exist from the current directory. So just adding the -R made cp copy it as a symlink with the final command being:

for f in `find . -regex ''.*cp.*snippets''` ; do cp -R bbb.html $f/ ; done

sake is a tool for system-wide rake tasks. It was created by Chris Wanstrath and is now maintained by postmodern. It provides a handy way to distribute generally-useful rake tasks. The advantage of sake over, say, a script in ~/bin is that 1) you have a predictable interface and 2) its easy to distribute tasks with sake -i http://any-url (in theory).

Examples

Ben Schwarz has written a great sake task for installing a ssh-public-key on a remote server. You can install it with sake -i http://github.com/benschwarz/sake-tasks/tree/master%2Fssh%2Fssh.sake?raw=true . (If you haven’t seen highline before, check it out. It’s a nice abstraction and clean alternative to using gets and puts.)

A sake task for installing remote git repos

Based on Ben’s task I’ve created a task for installing remote git repos.

The above task will do two things:

Create the bare repository on a foreign server
Optionally create a local working copy

There’s a bug in the above authentication code, did you catch it? For authentication, it will use your ssh keys if it finds it otherwise it will ask you for a password. However, if your ssh keys aren’t valid then it simply fails. Ideally it would ask you for a password and retry in this case.

I’m not too concerned about this however; if you’re creating a git repo remotely, you probably want to clone it and you also probably have your ssh keys setup to do so. (I probably shouldn’t be checking for a password at all.)

sake disadvantages

I believe sake is a great idea, but there is some rough edges in the current implementation.

Current Gem has a bug

Today, if you gem install sake there is a bug such that sake wont even run. Your best bet is to clone drnic’s repo sake >= 1.0.16 and install from there.

My guess is that this is because sake’s creator recently put out a request for someone to take over the project and the person who took it over hasn’t upgraded the rubyforge gem.

Task installation

Another bug that seems to be specific to this version of sake, when I run sake -i the task names and namespaces are created but the ~/.sake file contains no code.

Again, this just seems to be a minor bug with the current version and as such I see it as temporary. I’m planning on working on a patch on for this, though I’m not sure I’ll fix it before someone else.

Task development

The built-in way to do sake task development is to write a little bit, then sake -i your file, then write a little bit more etc. This gets old fast. Because of that drnic has written a great project for sake task development. In that project you run sake testrun taskname.

drnic’s project is handy and makes sake task development a snap. However, I think this fact could slow the adoption of sake; it’s a barrier to entry if you have to install a second project just to develop the first.

Even so …

I still think that the idea of sake is solid. There is definitely a need for easily distributable, reusable, system-wide rake tasks. Despite its current shortcomings, sake is definitely worth a look.

Organize all files in a given folder by date. This is commonly used to organize a “Downloads” folder. Currently this script will only move files more than 24 hours old. This is to protect against moving a file as it is downloaded.

Motivation

I love SafariStand. One of the features that I love is the sort-downloads-by-date feature. Now that I have moved to Firefox I really miss this feature. I been unable to find a good extension that will sort my downloads in a similar way. This script was written as an simple way to fill that gap.

Setup

I keep a ~/bin directory where I keep simple scripts such as this. Then setup a crontab such as the following:

*/10 * * * * /usr/local/bin/ruby /Users/nathan/bin/organize_folder_by_date.rb /Users/nathan/Desktop/Downloads

Acquiring

It is available on github: here (raw).
or

git clone git://github.com/jashmenn/download_sort.git

Open up Script Editor and paste this:

on open filelist
	repeat with i in filelist
		do shell script "qlmanage -p '" & POSIX path of i & "' >& /dev/null &"
	end repeat
end open

File > Save As…. Choose “Application” and save it somewhere it won’t move. I choose /Applications/ql.app.

Now simply choose ql.app next time you download a power-point file or set it up in Firefox’s Preferences > Applications.

qlmanage is the command-line tool to open files in Quick Look. By using AppleScript you are able to create this thin “application” that Firefox will trust and give a downloaded file (As opposed to a shell script, which Firefox will not let you choose as a file handler).

set mirror:order '*.jpg *.gif *.png *.js *.css * */'

This will send first jpg, then gif, then png files etc. This is very handy if you are mirroring an entire website and you want the images to go live before the html does.

1. cd into your directory where your db files are stored. In our case it was in the /usr…/data/mysql/ folder.
2. We then run the command:
   myisamchk *.MYI | grep -3 –color corrupted
3. This should give you some output on the current state of your files and indicate which files are corrupted and needing repair. It also gives you the next command to run on the line that reads:
   Fix it using switch “-r” or “-o”
4. So that is just what we did
   myisamchk -r file.MYI
5. Voila, your db should be repaired

Try editing

~/.bashrc

And adding:

alias screen='TERM=screen screen'

Not sure if this has adverse effects and there might be a better way to do it, but hey, it works!

Very handy to quickly view source, or edit any remote HTML/CSS, etc.

A first draft would be

s/\./-/g


but that gives you 2-640-849-0-jpg. Note the extension is transformed as well.

I could then do a second regex like s/-jpg/.jpg/ but that feels less than optimal.

The solution is a zero-width negative look-ahead assertion
man perlre for more information on this, but the basic idea is that
you match occurances of the preceeding expression that ate not followed by the zwnla.
For example /foo(?!bar)/ matches any occurrence of foo that isn’t followed by bar.

Combine this with the common perl utility rename and we get the following:

rename -n 's/\.(?!jpg)/-/g' *


Note that Matz has decided not to include the zero-width negative look-ahead assertion to Ruby.

UPDATE
Thanks goes out to Matt Pulver for submitting these improvements to the above regex:

This will handles cases like test.jpg.jpg

s/\.+(?!jpg$)/-/g


If you want to substitute all non-alpha-numeric characters and support other file extensions try:

s/[^0-9a-z](?!\w+$)/-/g

env has a nice option for clearing out all of the environment variables:

-i, --ignore-environment - start with an empty environment


Now you can try to run your script in an environment very similar to cron or monit. Note that this option even clears the PATH so you need to specify full paths or specify a PATH variable.

/usr/bin/env -i HOME=/path/to/my/home /path/to/do_script.sh

let rev=`cat REVISION`+1 && echo $rev > REVISION

Wrap that up as a nice shell script and you get a nice increment command:

#!/bin/bash
let rev=`cat $1`+1 && echo $rev > $1


[nathan@nate ~]$ cat REVISION
1
[nathan@nate ~]$ increment REVISION
[nathan@nate ~]$ cat REVISION

Create a 3-line file /etc/event.d/svscanboot :

start on runlevel [123456]
respawn
exec /command/svscanboot

That should start svscanboot with each system bootup. To have init start svscanboot without rebooting, do

start svscanboot

as root after creating the above file.
