I just updated the OpenCV on iOS Xcode project to use the git repo as a submodule for OpenCV. I've also fixed the SURF demo. Take a look!
(The git mirror that I had created for OpenCV's svn is now gone.)
Note: If you've cloned a previous version, use git submodule init and git submodule update after pulling the latest rev to pull the correct version of OpenCV. If you get build errors, you probably need to do this.
If you're new to the iPhone scene or working on In App Purchase code using a client's iTunes Connect setup, be aware that you must have all of your banking and financial information set up such that you *could* sell something on the app store, even if your app is not yet released, in order to test In App Purchase.
I have a client who hasn't yet released any applications. (SOON! Right, Randy?) We ran into this problem together and spent a couple of hours pulling our hair out over this one. I suggested that he go ahead and add his banking information before escalating the problem to our friends at Apple and everything started working one he got himself setup for payments. Unless I'm missing something obvious in the docs, and since there is no error message that comes back from the Store Kit callback indicating why an item is invalid, there is really no way that one would know that other than to have stumbled upon it like we did.

./contrib/gdata http://gdata-objectivec-client.googlecode.com/svn/trunk/ svn ./contrib/hgsubversion https://jonmarimba@bitbucket.org/durin42/hgsubversion hg ./contrib/mogenerator http://github.com/rentzsch/mogenerator.git gitIf you then run hg externals in the project. You'll see that the subversion, mercurial, and git repositories are checked-out much like subversion handles svn-externals. Note: Be aware that the hgexternals python scrip will actually run svn or git binaries in a subprocess, so svn and git will have to be installed for this to work properly. If you wanted to hold the external project to a given revision, which is usually a good idea, you just append the external version control system's usual revision flag. For example, if you wanted the Gdata Objective-C code pegged at revision 533, the first line in the .hgexternals file would look like this.
./contrib/gdata http://gdata-objectivec-client.googlecode.com/svn/trunk/ svn --revision 533In order to get the hg externals command to act a little more like subversion, you'll want to add the hgexternals.extstatushook to your .hgrc to get the status of the external projects when you type hg stat. To do this, you add the below to your .hgrc as suggested in the hgexternals installation instructions.
[hooks] post-status = python:hgexternals.extstatushookWith a couple of extra plugins, mercurial can pull from subversion and git, in addition to the usual mercurial repositories. If you prefer to let hgexternals shell out to git or svn (thus requiring you to use git and svn tools within the subprojects themselves), you can stop here. If you would like to use mercurial commands within all subprojects, regardless of whether they are Mercurial repositories, read on. Either way, we can now pull subprojects from anywhere and we can also use hg stat as we normally would in the working copy of the project and each subproject status will also be shown.
./contrib/mogenerator git://github.com/rentzsch/mogenerator.git hgWhat we're doing here is telling the mercurial hgexternals extension to pull from the git repository using mercurial itself. When hg-git is installed, this works with a git-based subproject just as it would with a Mercurial-based project. Make this edit to .hgexternals, remove the mogenerator directory that was checked-out with git, and rerun hg external command. Mercurial will now pull mogenerator from github and we can now work within the mogenerator subproject using regular hg commands.
./contrib/gdata svn+http://gdata-objectivec-client.googlecode.com/svn/trunk/ hg -r 533 ./contrib/hgsubversion https://jonmarimba@bitbucket.org/durin42/hgsubversion hg ./contrib/mogenerator git://github.com/rentzsch/mogenerator.git hgIf we remove the gdata subdirectory tha wall pulled using Subversion from contrib and rerun hg external so that Mercurial will now pull it using its hgsubversion plugin, we now have three projects in our contrib directory that Mercurial itself pulled from git, svn, and hg repositories. With Mercurial plus the addition of a few plugins, we now have an über distributed version control system that makes it much simpler to work with and to update external code from many different sources.
I'm performing a 5 minute "lightning" talk at the iPad/iPhone DevCon tomorrow and I'm not planning to use slides. I don't want to burn half of the 5 minutes getting keynote working, but hopefully attendees would like to have some of the links and code I'll reference. So! Here are my notes, links, and other such fodder. There is a lot more than 5 minutes worth of material here as I've been making notes about my habits for the last week or so; this is all of them. I plan to talk until I run out of air or out of time...

I often use Shipley's IsEmpty() to find out if some object is empty, rather than comparing its pointer to nil.
That way, nil messaging returning nil doesn't bite you in the ass when you're expecting something that is not an NSObject and you don't get that ugly (null) string in your UI. I hate that.

I've been a command-line user of subversion (svn) for some time and have long enjoyed these little bits of bash foo.
rm -rfv `find . -name *\.svn`The find . -name *\.svn finds all of the .svn folders that svn uses to track the repository and with the help of those handy back-tics, rm -rv does the recursive removal of svn tracking directories.
svn add `svn stat |grep \? |awk '{print $2}'`
Grep finds every svn stat output line that includes a question mark (meaning the item is not currently under version control) and pipes it through awk '{print $2}', which shows only the text (the filename) from the second column of the svn stat output. The back-tics and svn add finish the magic.
svn revert --recursive && rm -rf `svn stat |grep \? |awk '{print $2}'`
As with any other nerd foo, make sure that you really want to do what you're asking for when you use these commands. These make my life with svn just a little easier.

Some software is, in my experience, not quite WYSIWYG when it comes to the final printed output so I have gotten into the habit of viewing a PDF in preview before I actually send a document to my printer. This has saved many trees.
Apple makes it fairly easy to do this. Just command-P and click on the weird-looking PDF button to get the drop down menu to select "Open PDF In Preview."
I would like to see most every print job automatically open in preview without needing to take my hands off of the keyboard. One can make this happen with a little bit of effort, some help from Folder Actions, and a little piece of free third-party software. Here's how I do it.
First, download and install Cups PDF per the instructions on its home page. This will create a printer and driver that dumps a pdf file into ~/Desktop/cups-pdf/. Set your default printer to CUPS-PDF.
Next, you will setup a folder action on the ~/Desktop/cups-pdf/ to open each file that gets dumped in there in preview. I keep my folder actions scripts in ~/Desktop/Folder\ Actions/, so I put the following applescript (derived from a similar script that ships with Leopard) there.
(* add - new item alertThis Folder Action handler is triggered whenever items are added to the attached folder.
The script will display an alert containing the number of items added and offering the user
the option to reveal the added items in Finder.Copyright © 2002–2007 Apple Inc.

end try
end adding folder items to
Ctrl (or right) click the cups-pdf folder, Enable Folder Actions, then Configure Folder Actions via the contextual menues seen below.
When you select "Configure Folder Actions" you'll set the script that runs every time a new file is added to that folder to the one above.
Now every time you hit command - P to print in a application, you'll hit enter to print to your default CUPS-PDF printer, which will write a PDF to the cups-pdf folder on your desktop. The folder action will then pop-up this window (for five seconds).
All you have to do is hit enter.
So! Every time I print I hit command - P, enter, wait a sec, enter. Instant preview.
As you know from my last post, I have lots and lots of calendars. It used to be much much worse. Sharing calendars between my three Macs before Leopard server was a pain in the ass. Sure, you could put a calendar on a regular DAV server and subscribe to that calendar on your other machines, but you could not write to that calendar from any machine other than that which created it initially. All subscribed machines were read-only. What does this mean to me? You know about my 14 calendars, right? Triple it. That's right. I used to have 42 calendars on each of my 3 machines. 14 calendars to which I could write and 28 to which I was subscribed so I could read any appointments from my other two machines. What a mess.
Leopard calendar server has brought me back to a debatably sane 14 calendars. But how does one migrate all of those calendars spread across multiple machines onto the shiny new calDAV server? Like so:
1. Subscribe to your shiny new calDAV server (under the Accounts tab) in iCal preferences.
2. Create a new calendar on your calDAV server through iCal (File Menu -> new Calendar -> your server) for each of your 14 calendars.
3. Create a *.ics file from your old calendar by:
a. Selecting the calendars you want to export by using the export functionality in iCal (File Menu -> Export) on each of your machines or...
b. Mounting your DAV server and downloading all of 'em at once (assuming you're keeping your calendars on a DAV server now, which I was, this method is a lot easier for obvious reasons)...
4. Select the calendar from the source list (one residing on your new calDAV server) and import the *.ics files you wish to store in the new calendar (File Menu -> import).
Your appointments are now on your calDAV server and will show up on all of your subscribed machines fully editable from all.
I'm scheduled to within an inch of my life, so there is no surprise that I have 14 calendars in iCal right now. I have calendars for billable hours vs. non-billable hours. I have calendars on my calDAV server that I share with clients, some under a different username than others, and some that I use to synchronize personal calendars across multiple machines, and yet another that I share with my assistant. (Hi Christina!) I have calendars coming out my ears from various sources.
Very often, I'll place an appointment in one calendar and later wish to move it to another. Perhaps I'll have a tentative appointment with a client, so I'll put that in my non-billable calendar. When that appointment happens, perhaps I'll put that into my billable calendar. Unfortunately, my billable calender is under a different username on my calDAV server than my billable calendar (one of them I share, the other I do not). Normally, when I want to move an appointment from one calendar to another I right/ctrl-click the appointment and select the calendar I want to move it to. Unfortunately, the only calendars listed in that contextual menu are those under the same user account as the appointment I'm trying to move. Bummer.
The workaround:
1. Select the appointment you would like to move.
2. Use your favorite method of getting it to the clipboard (I use command-X to cut)
3. Select the calendar from the source list to which you would like to move the appointment
4. Paste (command - v for me)
All appointment data when cut or copied is retained when pasted into the other calendar.
Wouldn't it be nice to have ALL of your calendars in the contextual menu? Radar: 5593635
For those wishing to use Mozilla Sunbird with the calDAV server that comes with Leopard, it's not setup in Sunbird in (quite) the same way as it is in iCal.
Let's say you have the calDAV Account URL working in ical (which will subscribe you to all of your calendars) and its URL is
https://somedomain.com:8443/principals/users/username/
In Sunbird, you'll have to subscribe to the your calendars individually. Every calDAV user I've setup so far in Leopard server has been given a default calendar called simply "calendar", which you can subscribed to from Sunbird at
https://somedomain.com:8443/calendars/users/username/calendar/Easy enough. However, if you add a new calendar in iCal, it will create a calendar named with a UUID. In order to figure out what that UUID is, it's easiest to just mount the calDAV in the finder (Command - K) at
https://somedomain.com:8443/calendars/users/username/You'll see several directories in there: calendar, dropbox, oubox, notifications, etc. The one that looks like a UUID (for example, 037D3206-9C1D-4C6C-8E54-B3E3CAF90ABF) is the directory you'll want to subscribe to in Sunbird. In the example above, you would subscribe to
https://somedomain.com:8443/calendars/users/username/037D3206-9C1D-4C6C-8E54-B3E3CAF90ABF/

Carburetor tuning:
Even when you're doing it right, anything you change in one system will often screw something up in another unexpectedly.
Sometimes starting over from a reasonable baseline is better than hammering away at a not-quite-right but oh-so-close-to-working plan.
Keeping track of what you've done makes it easier to get where you want to be, even if what you've done has sucked grapes.
...funny. Writing music works the same way, too... and so does writing code.
The native iPhone hack I put together for the C4[1] conference is in the process of a "wow, I hope somebody can read this code someday" cleanup. I will release the source in the coming days. Stay tuned for a download link.
In the meantime, here are a couple of teasers.
Screenshots:
And here is some code for playing a sound file from your native iPhone Application's bundle (with the class-dump'd headers you'll need, too). The iPhone, as was mentioned by everyone with a native hack at C4, has some really intelligent API. Hats off, ladies and gentlemen, to the iPhone team. They must be having a grand ol' time internally playing with this thing.

I found an easy way to add Google Analytics to a movabletype blog as well. There is a small plugin that puts the javascript on your page available here. I love it when others write code so I don't have to.
I’ve been thinking of setting up google analytics on my site for a while now and have finally taken a few moments to get started. I'm curious to see where folks are coming from and am kind of tired of writing one-off scripts to grep my apache logs.
If, like me, you have a site made of many many html pages, this one’s for you. (DO please make a backup of your site and configuration files before you start).
In order for google to analyze a given web page, you need to add a short javascript to each. It looks something like this:
<script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
</script>
<script type="text/javascript">
_uacct = "XX-XXXXXXX-X";
urchinTracker();
</script>
Each html document you want google to track will need to include that file’s text immediately before the </body> tag through the placement of a small SSI tag.
It will look something like this:
<!--#include virtual="/data/included.html" -->
perl -p -i -e 's/<body<!--#include virtual=\"\/data\/included.html\" -->\n <body/g' `find . |grep \.html`
If SSI isn't yet configured on your apache box, there is a simple set of tricks that will make life MUCH easier. Assuming that you have compiled mod_include (most apache installations have this), you simply need to add
Options +Includesto your site configuration. I placed it in my virtual hosts file along with my other Options directives. The real juice is here: place
XBitHack onin your apache configuration as well. This will make apache parse any file (looking for SSI includes) with the execute (remember your unix permissions?) bit enabled. You will then set the execute bit on all of your html pages like so:
cd your/apache/htdocs
chmod +x `find . |grep \.html`
Note: XBitHack will not work on windows for obvious reasons. There is no executable bit on windows. See the apache tutorial referenced above for other methods to enable SSI if you're on windows.
I had an interesting Apache gdb session recently wherein I discovered that the Apache Portable Runtime (APR) package on one of my clients' shiny new Debian Linux boxes was.... well ... completely borked, causing a segfault for every apache child process. It's my fault for using the testing distribution, but (hey!) the box isn't all that important and it's an excuse to see what's new in Debian-land. However, as I actually do want to serve a web page from this machine, I figured it best not to further trust the package manager to find me non-broken software. I decided to download APR and friends + apache and compile it myself. The last time I did anything like this, I used MacPorts (then darwinports) to compile and install apache on my mac at home, a very "batteries included" affair as MacPorts selects a good set of default options for me. After some attempts to grok the various configuration options for Apache, I decided that I really just wanted the same options I have installed on the MacPorts+OSX box at home. Enter MacPorts happily human readable portfiles.
In the MacPorts portfile for apache we find the configure.args line.
configure.args --with-apr=${prefix}/bin/apr-1-config --with-apr-util=${prefix}/bin/apu-1-config --libdir=${prefix}/lib --with-expat=${prefix} --with-pcre=${prefix} --mandir=${prefix}/share/man --enable-mods-shared=all --enable-ssl --with-ssl=${prefix} --enable-deflate --enable-proxy --enable-proxy-connect --enable-proxy-http --enable-proxy-ftp
All that was necessary was to make the prefix variable point to where I wanted to install apache, drop in the args above for the ./configure script, and everything compiled without a hitch. I did already have the various other dependencies (ssl, etc.) installed on my system from the aborted attempts at installing the Apache2 package, so there were no surprises from missing libraries. Editing the (happily very clear and atomic) default apache configuration files a little brought me to the necessary service configuration very quickly. Now I have virtual hosting, mod_rewrite (to send all requests on port 80 to the https port), and some other nice features running on the very latest stable Apache2.
"Reality isn't virtual enough."
Seriously. I just heard this at a game design panel.
Looks like the Nike+ data gets... um ... just a little smoothing / averaging. Then again, I still need to test the data importer... You're looking at distance reported per 10 second interval. Raw data babeeee.
With the help of Drew Thaler's instructions on how to grab disk access by running an app in gdb, it looks like the bug in Parallels Workstation was even weirder than the case-sensitivity problem. Parallels uses QT, a cross-platform GUI toolkit to handle user interface presentation, rather than the much-more-common-on-OSX-but-not-cross-platform toolkit called cocoa. Unfortunately, it follows my library search path to get to QT. My installation of QT is broken. (I've known this for a while and haven't had the time to rebuild it from source). Why doesn't Parallels force inclusion of QT from the app bundle? I don't know. Bug report filed.
See the extended entry for Drew's instructions (thanks Drew!)

I don't know how he finds the time, but the python / mac community owes Bob several rounds of applause. Let me be the first to stand (soon as I get this here foot outta mah mouth). I'm also wowed at how he managed to find my blog and comment before I got round to sending a question to the mailing lists. And ... well you know... he kicked my butt and I deserved it.
I wonder if I'm using cocoa bindings incorrectly... or maybe there's a bug. Usually when I start to think "maybe there's a bug in somebody else's code," I look for ways in which I'm using that code in weird (wrong) ways. I figure that the pyobjc people are about 7 orders of magnitude better at this than I am.
I've been learning cocoa bindings (I like this voodoo) and have hit a brick wall. I've been asking pythonmac-sig if they've any ideas and they pointed me in the direction of NSZombieEnabled, but i haven't been able to get very far.
I have an NSArray controller with a python object subclassing NSObject. I've put a + button on the gui to add the python object like this:::
def addTriggerModel_(self, sender): # BUTTON
self.setCanAddTriggerModel_(False)
newTriggerModel = scNSDrumTriggerModel.alloc().init()
newTriggerModel.resetWithNodeBusAndInput(node = self.nextNode, bus = self.nextBus, \
input = self.nextInput, sendInfo = self.sendingTriggersToClient)
self.nextNode += 100
self.nextBus += 10
self.nextInput += 1
NSLog("Adding newTriggerModel")
self.triggerArrayController.addObject_(newTriggerModel)
NSLog("Added newTriggerModel")
self.setCanAddTriggerModel_(True)
This works just peachy the first time I do it, but fails on a second addition of the new scNSDrumTriggerModel object. At first I was getting Signal 5/6 errors, then I did:
from PyObjCTools import Signals
Signals.dumpStackOnFatalSignal()
from PyObjCTools import Debugging
Debugging.installVerboseExceptionHandler()
This told me:
NSGenericException - *** Selector 'retain' sent to dealloced instance 0x1147cb0 of class OC_PythonArray
So I turned on NSZombieEnabled and tried running in gdb with a breakpoint on -[_NSZombie retain], but I don't really know what I'm looking for. I'm looking at a lot of hex memory addresses with very little human-readable stuff in there.
I tried setting a breakpoint at (+[OC_PythonArray newWithPythonObject:]) to see perhaps what proxy objects are being instantiated, but I'm clearly in over my depth. The variable corresponding to the pythonObject in OC_PythonArray newWithPythonObject: up there ^ has address 0x0 (Is that a null pointer?) in gdb each time I hit that breakpoint.
When I run malloc_history on the memory address that the NSZombie has, I get this:
Anyone who has tried to comment on my 'blog, please try again. My server was blocking outgoing smtp and I wasn't getting the notifications to approve comments.
oops.
So I've been going 'round and 'round (including sending a DVD-R via UPS RED which - I'm told - was corrupted upon arrival) to get a binary database save file to the company that handles the database maintenance at one of my clients so that they can perform an upgrade to the system.
I finally bit the bullet... and did everything I could think of to make sure that the file got there intact:

Stupid nerd trick: (File under... DUH!)
When working on real-time audio control, it's probably not a bad idea to try to get the best possible time-slicing quantum possible. What with latency to think about and generally wanting everything to just-happen-right-the-heck-now(TM)...
