Apple Posts

So this post from 1997 titled “101 Ways to Save Apple” made it to the front page of Hacker News today. Ahh, what a great look back to a time that really doesn’t seem like it was that long ago. It was only 17 years ago, but the Apple of 1997 and the Apple of 2014 might as well be completely different companies.

So this past week I attended the first (I think) Cocoaconf to be held within a reasonable distance of Huntsville. In this case, a mere 3.5 hours away in Atlanta. Overall, I’d say this was a very good conference. It was small (I’m guessing about 150 or so attendance). The location was easy to get to, and the conference in general seemeed well organized.

Since it’s been awhile since I wrote a post about what I use in regards to software, perhaps it’s time that I did that again. So here’s a list software I’m using in 2013:

Download I recently added a Mac mini to my setup at home, that I’m using to drive my in-home “video on demand” system. With many of the TV’s in the house on AppleTVs, any TV in the house can watch any movie in the library at any time. I put the mini (headless) in the closet, along with the Drobo and a printer. But, the new Mac mini lacks an optical drive. So, how to continue ripping the DVDs I already own? The solution, it turns out, is to continue doing the actual work on my iMac when it comes to ripping, filtering the files through iDentify and MetaX. But I don’t want to have to go to screen sharing on the Mini and add a file to iTunes. I want that to happen automatically. That’s where Automator - one of the most underrated pieces of software that comes with every Mac - comes in. With Automator, you can attach an action to a folder, so that that action will be performed whenever anything is added to that folder. So here’s what I did to get files from a folder into iTunes: Create a folder somewhere on your system. I put mine in my user directory. Open Automator. From the dialog box, select “Folder Action.” At the top, where it says “Folder Action receives files and folders added to,” select “Other” and select your new folder. Search for an action called “Set Var of Value”. Drag that action over to the right. From “Variable” select “New Variable.” Call it “Source” Search for an action called “Import Files into iTunes”. Drag that action over to the right underneath the variable action. Be sure to select “Library” from the empty dropdown. Search for an action called “Get Var of Value”. Drag that action over to the right underneath the iTunes action. Be sure the selected variable is “Source”. Search for an action called “Move Finder Items to Trash”. Drag that action over to the right. Search for an action called “Run AppleScript.” Drag that action over to the right. In the AppleScript action, paste this: on run {input, parameters} tell application "Finder" to empty trash return input end run Save the action. You’re done.

Unless you’ve been living under an Internet rock, you know that Apple released a new version of iOS, featuring a much heralded new mapping application. This application replaces the old Google Maps application. You also probably know that it has been roundly criticized and mocked. Now, before anyone accuses me of blatant fanboyism (although, without a doubt, I am an Apple fanboy), the new Maps application sucks. It’s a step backwards from the previous one, lacks some of the features the previous one had, and is generally disappointing. I especially don’t like how it didn’t degrade gracefully on the iPhone 4 (no voice turn-by-turn, and, for some strange reason, it seems unable to count down the distance to the next turn). In general, it clearly isn’t ready for primetime, Apple over-advertised it, and I think Apple could have done better. But, other than being disappointing, the new Apple Maps application has no real impact on me because I never used the old one. It sucked also, and I think people are forgetting just how badly the old one was allowed to languish without significant updates. The Google-based Maps app in iOS 5 was essentially unchanged from the one that was released 4 years earlier. Here are some things that were wrong with the “old” Google-based Maps app as of iOS 5: No voice turn-by-turn directions. Had to manually advance while driving when doing directions. Searching sucked: you had to spell things exactly right or it wouldn’t find them. For some reason, it thought I lived in Madison, Wisconsin all the time. If you live in anywhere but a large city, it was essentially useless for navigation. You could maybe find an address, if you knew exactly what you were looking for, but you couldn’t safely get there in a car. In short, I long ago abandoned the built-in mapping application for better services available in the App Store. I’ve been using the free Mapquest app for the last couple of years, and it’s worked great. It’s gotten better with each iteration, to the point where it’s pretty much my sole navigation app now. My process flow as usually been search for an address in Safari (or get it from another app like Yelp or Urban Spoon) and paste it into Mapquest, or search in Mapquest (usually with a little better luck than the built-in Maps app). Bam. Reliable turn-by-turn voice navigation that actually works on my iPhone 4. Pair that with the new Bluetooth stereo I put in my truck, and it works like butter. If it would just do night colors, it would be damn near perfect. Now, if I lived in a big city, I can understand being upset with the new app. Lacking walking or biking directions and public transit directions seems a curious oversight considering how many of Apple’s iPhone customers live in those environments. I can’t really understand why Apple would leave that data out unless they simply could not get it, and I hope they address that soon for all the people that do rely on it. But, for me, the new Maps app sucks just as much as the old one did, and I will not use it just as much as I didn’t use the previous one. So, for me, nothing has changed. Just, more than anything though, I’m disappointed in Apple, for two reasons. One, that they couldn’t get this right, and two, that they released it in spite of what they had to know were serious problems with it, all while heralding it as one if iOS 6’s killer features. Especially in light of news that they still had a year on their Google maps contract, I would rather they have spent that year fine tuning it rather than release something that clearly wasn’t ready for primetime.

As I’ve mentioned a couple of times before, one of my projects right now is ripping all the DVDs I own so that I can watch them on my AppleTV (or any AppleTV in the house). Well, one of the problems I’ve run into a couple of times is longer movies that are distributed on two discs. This is usually movies like the Lord of the Rings Extended Edition or The Ten Commandments. Really, they’re one movie, but are distributed as two separate movies because of the restrictions of physical media. Well, digital media imposes no such restrictions on us, so why have two separate movies listed on the AppleTV? So after much trial and error, I finally discovered a way to get everything play nicely together. Unfortunately, this is not an easy problem to solve and even involved me writing a small script that could merge chapter files together because every single method I could find would eliminate chapter markers. So here, in abbreviated form, is the process for merging m4v files together and preserving chapter markers. Note: This tutorial assumes some level of technical proficiency. This is not a point-and-click process (yet :P) and requires the use of multiple tools and the shell. Tools you’ll need: Handbrake or whatever tool you’re using for ripping your legally obtained DVDs. MetaX and/or iDentify Subler remux Quicktime, which is now built into Mac OS X. chaptermerge, a script I wrote that merges chapter files together. The proces: Rip both movies from their individual DVDs using Handbrake or whatever other tool you’re using. Be sure that you’re adding chapter markers. Load each movie into MetaX and download the chapter names. That’s really the only thing you need to add to the file. Save the files with chapter names. Load each movie into Subler and extract the chapter files. To do this, select the chapter track and select File -> Export. Now, open the first movie in Quicktime. Drag the second movie on top of the first one. Quicktime will add the two together. Save the movie for use on an AppleTV. Get a beer or 6, because this takes awhile. While the movie is saving, use chaptermerge to merge the chapter files together. See the docs on how it works. Once the file has finished saving as a Quicktime MOV (it’s actually still h.264 inside the file), fire up remux and convert the merged file back into an m4v. Drag the file into remux, set the output to m4v, and save. Should be pretty quick - a matter of minutes. Load the merged file back into Subler and add the merged chapter track. Drag the chapter file into the Subler window. Save the file. Load the merged file into a tool such as iDentify or MetaX and add the remaining metadata. That’s it! You now have a merged file with both parts of the movie, accurate chapter markers and full metadata, ready to be copied to iTunes and viewed on your AppleTV.

Been having some problems with my iMac upstairs. I’m pretty sure the hard drive is failing (again), although hopefully it’s just bad sectors. But, with hard drive prices currently still in the stratosphere, I decided to try one more last trick to see if I can save myself some money. That is, the old Windows trick: fdisk, format, reinstall. Or, well, the Mac Equivalent - Disk Utility, reinstall. About a year ago, a bought a Drobo. I’ve been meaning to write a review of the Drobo and maybe now I will (the short of it is, I had some growing pains with it, but now that I’ve figured out its quirks, it seems to work well). One of the reasons I bought the Drobo as to use a shared Time Machine backup store for all the Macs in the house. So, I thought, in addition to trying to save my Mac, now would be a great time to test my fancy Time Machine backup system. And, unfortunately, since Time Machine really isn’t meant to work with unsupported network volumes, it does require some gymnastics to get it to work. Even worse, it isn’t a very well documented procedure. But, ultimately, I was able to figure it out; I’ll post what I did hoping that maybe it will save someone some time and headache. First step is to format and reinstall as you normally would. If you are on/installing Lion, you may be presented with an option to reinstall from a backup as part of the install process. Don’t do this. Reinstall Lion as if you were performing a fresh install. When the installation is complete and you get to the Lion post-install setup screens, you will (eventually) reach a screen asking you to create a user account. Create your original user account (same username) as in your backup. Once you’re out of setup, go to System Preferences, then Users. Create a new administrative level user (I called mine “foo”). Be sure this is an admin-level user. Log out and log into the account you just created. Turn on unsupported Time Machine volumes. Open up a Terminal window and enter: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1 Now, open up a finder window and navigate to your Drobo or other device and to whatever network share you have your Time Machine backups stored on. Mount it. Now, inside the share, mount the .sparsebundle that is your restore image (it should be the machine name). If you open it, you should be able to see a folder called “Backups.backupdb” in it. Next, fire up the Migration Assistant. Select “From another Mac, PC, Time Machine backup, or other disk.” Hit continue. Select “From a Time Machine backup or other disk.” Hit continue. It may take a second, but, eventually, you should see a drive image and the name of your old hard drive (usually “Macintosh HD”) appear. Click continue. It may take awhile for it to parse the image. My backup image was about 350gb, and it took about 20 minutes to parse out all the information. Select what you do or don’t want and click continue. You should be presented with a dialog stating that a username on the system is the same as one in the backup. Select “Replace…” Click continue. Wait. It will take awhile. It took about 5 hours for me to do a complete restore from a backup on the Drobo to my iMac. And that’s it. Once it finished and you reboot, your Mac should be just as it was during the last backup.

Over the weekend, I was having some hard drive issues. While I think I fixed the issues, I’ve been keeping a close eye on my console (Console.app) to look for any hints that the issues are more major than those that can be repaired by Disk Utility. However, while watching my console, I noticed something: there are a LOT of spammy Mac apps out there! Most Mac/Objective-C developers are aware of the NSLog() function, which, while in an Xcode environment, outputs data to the Xcode console. It’s usually one of the first things a new developer learns about and it’s very useful for debugging. What many developers may not realize is that NSLog() continues to output data to the system logs even when the app is not being run from within Xcode. As a result, the console fills up with messages that don’t mean a whole lot to people looking at the console. Now, I don’t want to come across as saying you should never use NSLog() outside of Xcode. There are times when outputting debug data to the console is fine. But some of the things I see are people echoing objects into the log or short text strings that are obviously method names. These aren’t helpful to people looking at the console and, arguably, aren’t helpful to a developer once an app is in the wild. Once your app is in the wild, data in the logs should indicate error conditions in your app. NSLog() is fine for debugging in Xcode, but you should be careful to remove them when you’re done. A good question I ask myself before leaving an NSLog() in place is, “if a user filed a support request with this data, would it help me fix their problem?” Most of the time, the answer is no. So before releasing an app, do a quick search in your project for all uses of NSLog() and evaluate whether they are really needed.

A couple of days ago, I upgraded to the most recent version of Netbeans - 7.1.1. I had been running a 7.1-DEV nightly from back in 2011 and just hadn’t bothered to upgrade yet. The first thing I noticed is that this version of Netbeans introduced a “feature” that allows you to zoom in or out of text. This is accomplished by, on the Mac, holding down the Command key and scrolling on the trackpad. The problem with this is that it is very easy to trigger accidentally - to the point where I was doing it multiple times a day. Even more irritating, there was no indication as to what the zoom level was or easy way to revert to normal view. If you trigger it accidentally, you just have to kinda zoom back out until you find a setting somewhat similar to the rest of your tabs. Fortunately, someone on the nbusers mailing list mentioned how to solve this problem, so I want to post it here in case anyone else gets as lost and frustrated as I was. Open the preferences page. On the Mac, you would go Netbeans Menu -> Preferences. Go to Keymaps. Search for “zoom”. Remove the bindings for “Zoom Text In” and “Zoom Text Out.” Double click on the Shortcut and hit backspace twice.

Another small update to the Mac Oil Price Widget has been released. This fixes a small bug that resulted in the negative symbol continuing to be visible. Not really necessary because the widget itself says “Up” or “Down.” You can download it over on it’s page.
