I spend most of my development time split between Rails and iOS. Each offers a rich API that makes building projects much more productive and enjoyable. There is one place, however, that Ruby clobbers Objective-C: testing. Read More
I have posted the slides from my talk on networking with Cocoa at CocoaConf. For those that attended: thank you! It was great meeting so many new people and having the opportunity to present.
One common suggestion for improvement from attendees was for demos. These are always tricky with networking topics, because you never know how good the Wi-Fi will be at a conference. When I give this talk in the future, I think I will split it into two, build some demos, and bring a second laptop with a cross-over cable.
Now that Apple has released the complete set of WWDC 2011 videos to registered developers, those of us who couldn’t make it to the conference have the opportunity to hear about all the new, shiny stuff coming in Mac OS X 10.7 and iOS 5. Read More
CocoaConf is a new developer-focused conference for Mac OS X and iOS being held August 12-13 in Columbus, OH. I am presenting a session on networking with Cocoa. It will cover the various APIs available to Mac OS X and iOS developers from Apple and third-parties, as well as touch on issues unique to using the network on a mobile platform.
Early registration opened today and you can get a conference pass for 50% off.
If you’re (re)building a development workstation on Mac OS X, you may have decided to use the latest MySQL 5.5 packages from mysql.com. Unfortunately, that means you probably have seen (or will soon see) two problems. Read More
Much has been said over the last 2½ years about the App Store and places where Apple is failing third-party developers. Many things have been fixed, but unfortunately, many more have been neglected or only partially addressed. On January 22, 2011, the App Store surpassed 10 billion downloads. Let’s assume 1% of those are paid and Apple only takes the minimum 29¢ for each one. That’s still $29 million. Apple needs to do a lot more to earn their 30% cut. Read More
Following up on my post about automatic Subversion revision stamping, here is a modified script for use with Git-based projects. Read More
I found this on SuperUser today and just have to share it.
In Terminal, you can reposition the cursor on a line by option-clicking where you want it to go. Credit where due.
It doesn’t happen every day, but certainly a few times a week: I end up with a monster command, spanning two full 100 character wide lines or more. Inevitably, there’s an error in there in the middle, and I sit waiting, holding down left-arrow to fix it and try again.
PostgreSQL is my database of choice. The main reason is that a standard distribution comes with just about everything one could ask for in a free RDBMS, and if what you want isn’t already installed, it’s often in the “contrib” directory. In particular, now that I’m doing a lot of iOS development, and location awareness is a big part of mobile apps, it’s useful to be able to work with coordinates. PostgreSQL does this using the cube data type and earthdistance functions, both in “contrib”. Read More
These days, it’s not uncommon to be faced with the situation of having two or more Wi-Fi devices you might wish to use in a hotel room when the hotel does not provide free in-room Wi-Fi. The hotel doesn’t know that those devices are all yours and in one room, so using them means paying per device, which is crazy.
This explains how to easily set up Internet connection sharing in Mac OS X 10.6 so you can pay once, and piggyback the rest of your devices off that one laptop. These instructions assume that you have a wired Ethernet connection available in the room.
That’s it: you should now be able to use the Internet from your wireless device, via your laptop plugged into the Ethernet.
