My custom Alfred.app searches

I thought others might find a couple of my custom searches and fallback searches for Alfred.app interesting. When I type some text that doesn’t match anything, here’s what I get:

The “Jira search” entry searches my company’s local Jira server. You can add one for yourself by clicking this link and editing the URL in Alfred Preferences | Features | Web & URL | Custom Searches (this is in Alfred.app version 1.3.1).

The “OF Inbox” entry uses an omnifocus:// URL to send the text to your OmniFocus Inbox. Here’s a link to add this to your Alfred config.

OS X Lion: Restore windows when quitting and re-opening apps

Posted on by

I just upgraded my work laptop to Lion recently.

After the reversed scrolling behavior, the next big annoyance was that when I launch apps they open with all of the documents that were open when I quit them. This was particularly noticeable and annoying with Preview.app and Microsoft Word, because I typically open these to quickly look at something and then I quit them.

If you’re wondering how to turn this behavior off, uncheck the box shown below in System Preferences | General | Restore windows when quitting and re-opening apps:

OmniFocus extension for PopClip

I just hacked together an OmniFocus extension for PopClip

The extension creates a new task with the selected task in the OmniFocus quick entry window. Just a tiny bit of AppleScript.

Installation

Unpack into ~/Library/Application Support/PopClip/Extensions/OmniFocus.popclipext and then open the extension by double-clicking in Finder or using the open command.

iTerm2: How to unsplit a pane back to a tab or window

Posted on by

This morning I accidentally dragged an iTerm2 tab and created a split pane in one of my tabs. I searched for quite a while to find out how to move it back to its own tab. Finally, I found it at http://groups.google.com/group/iterm2-discuss/browse_thread/thread/920ff96f710a0a93:

You can already do this by holding cmd-shift-opt and dragging the pane to a
tab bar or away from any terminal window to create a new window.

Don’t be alarmed by super large VSIZE on OS X

(Also at https://github.com/urbancoding/jenx/issues/32)

Don’t freak out too much if 64-bit processes on OS X have a VSIZE of 10 GB or more.

What this shows is a ridiculously simple Ruby program (running under MacRuby) having a VSIZE of 10 GB.

OTOH, Activity Monitor shows up a much more sane “Virtual Mem” of 315.0 MB for this process:

Also, vmmap seems to indicate that most of the virtual memory comes from “reserved VM address space (unallocated)” and it seems to consider this as unimportant:

This issue, by the way, is not specific to MacRuby (my initial suspicion). I saw a similar pattern with Xcode, which also has a VSIZE of around 11 GB. I did not see this pattern with MRI Ruby [ruby 1.9.3p0 (2011-10-30 revision 33570)], Mail.app, Finder, iTerm, Alfred, Safari, or mysqld — these apps all have a much lower VSIZE of around 3 or 4 GB each. I have no idea why.

OS X appears to “reserve” a large amount of virtual memory for 64-bit processes, but they are not necessarily using it just because it’s been reserved for them.

brew install growlnotify-1.2.2 on OS X 10.6 (Snow Leopard)

The latest growlnotify in homebrew (1.3) fails on OS X 10.6 (Snow Leopard), because it’s a Lion-only binary.

marca@SCML-MarcA:/usr/local$ growlnotify

Here’s how to fix it (thanks to https://github.com/mxcl/homebrew/issues/8316):

Easy access to TrueCrypt from the command-line in OS X

Posted on by

TrueCrypt on Mac OS X has a nice GUI, but if you’re a command-line afficionado…

Put this in your ~/.bashrc or similar file:

alias truecrypt='/Applications/TrueCrypt.app/Contents/MacOS/Truecrypt --text'

Then you can do stuff like:

$ truecrypt
Usage: Truecrypt [--auto-mount <str>] [--backup-headers] [--background-task] [-C] [-c] [--create-keyfile] [--delete-token-keyfiles] [-d] [--display-password] 
[--encryption <str>] [--explore] [--export-token-keyfile] [--filesystem <] [-f] [--hash <str>] [-h] [--import-token-keyfiles] 
[-k <str>] [-l] [--list-token-keyfiles] [--load-preferences] [--mount] [-m <str>] [--new-keyfiles <str>] 
[--new-password <str>] [--non-interactive] [-p <str>] [--protect-hidden <str>] [--protection-keyfiles <str>] 
[--protection-password <str>] [--random-source <str>] [--restore-headers] [--save-preferences] [--quick] [--size <str>] 
[--slot <str>] [--test] [-t] [--token-lib <str>] [-v] [--version] [--volume-properties] [--volume-type <str>] [Volume path] [Mount point]
...

or:

$ truecrypt --text --non-interactive --password=(password) --mount /Users/marc/Dropbox/TrueCryptVolume.truecrypt /Volumes/TrueCrypt

marc@hyperion:~
12:31:43 $ ls /Volumes/TrueCrypt
Audio/     Backups/   Documents/ Taxes/

or:

$ truecrypt --list
1: /Users/marc/Dropbox/TrueCryptVolume.truecrypt /dev/disk4 /Volumes/TrueCrypt

or:

$ truecrypt --dismount
$ truecrypt --list
Error: No volumes mounted.
