BEN: Sounds like you need a shot of espresso, Chuck. [Laughter] JAIM: Do pushups maybe, you know. ROD: Cold shower. CHUCK: Cold shower, yeah. [Laughs] CHUCK: Hey everybody and welcome to Episode 26 of The iPhreaks Show! This week on our panel, we have Rod Schmidt. ROD: Hello from Salt Lake City! CHUCK: Ben Scheirman. BEN: Hello from Houston! CHUCK: Jaim Zuber. JAIM: I’m good enough, I’m smart enough, doggone it, people – sorry. Hello from Minnesota! BEN: [Laughs] JAIM: Can you believe that guy is my senator? CHUCK: [Laughs] JAIM: No. He don’t get back to work. I don’t know what’s going on here. CHUCK: [Chuckles] I’m Charles Max Wood from DevChat.tv, with a quick reminder to go check out GoingRogueVideo.com. I have a 30-minute video on how I went freelance. And we also have a special guest this week, and that’s Sam Davies. SAM: Hello there from Bristol, the UK! CHUCK: Do you want to introduce yourself for the people who don’t know who you are? SAM: Sure! I’m Sam Davies. I work now for a company called ShinobiControls, and we build various different UI controls for both iOS and for Android and things. All kinds of different things; I’m not going to [unclear] you with exactly what we do, but charting and all kinds of different to help people’s [unclear]. I stay at that life as a computer vision researcher back in the day a few years ago. I spent a while of doing that. But Academia just doesn’t really have any money so I had to leave Academia and go do something a bit more applicable so I started doing mobile development and kind of stuff at working machine over a few years ago. Now, I work as a developer evangelist so kind of writing different bits and pieces and teaching people about things as well. I like talking to devs and doing dev work as well. CHUCK: Very nice. We brought you on the show to talk about “Custom UIControls”. SAM: Yup! I guess, sure, I’d talk a little bit about what – what they are and why you would want to make custom UIcontrols. CHUCK: Yeah, that sounds like a good start to me. SAM: UIControls, we all know exactly what UIControls are because we use them all the time, but what that actually means for somebody who’s using something that really helpful for lots of different groups of people including designers, developers, and for the end user as well. They represent a common vocabulary of ways and what you interact with an app. So we’re all used to UIControls in iOS because we have things like UISliders, we have Buttons, we have segment of control, whole selection of different things, and they were really, really useful. But the question always comes when you get to the stage where you want something that doesn’t quite – whether the existing ones from iOS don’t exactly do what you want to do – you want to have something slightly different. An example I always give whenever anybody wants to talk to me about this kind of thing is,

  CHUCK: Hey everybody and welcome to Episode 25 of the iPhreaks Show! This week on our panel, we have Rod Schmidt. ROD: Hello from Salt Lake! CHUCK: I'm Charles Max Wood from DevChat.tv. I just want to give you another quick reminder that you can find out about my freelancing journey at GoingRogueVideo.com, it's a 30-minute video detailing how I went from laid off to freelancing successfully. We also have a special guest, and that is Jeff Biggus. JEFF: Hello! CHUCK: Since you haven't been on the show before, Jeff, do you want to introduce yourself? JEFF: Sure! I'm a Mac and iOS programmer, I work for my own company, have for about 17 years now. Lately, it's been all Mac and iOS, maybe for the last 7 years or so, and I come from a background that's maybe more science, like academic science, but now I do a lot of just general programming stuff. CHUCK: Awesome. What kinds of things have you been academic-ing or studying or whatever? JEFF: [Chuckles] I used to do a bunch of computational physics stuff. So I was in the physics world for a while, and before that, I was an electrical engineer.  It was a lot of very practical engineering type programming. Ugly code that got the job done. CHUCK: Boy! That sounds like what I do! JEFF: [Chuckles] CHUCK: Ugly code that gets the job done. JEFF: Exactly, yeah. Which is basically what I do now; except it's a little more elegant these days. The tools are much nicer. CHUCK: Awesome. So, we brought you on today to talk about the Accelerate Framework. JEFF: Yeah. CHUCK: It's part of the standard suite of the libraries you get from Apple, it looks like. Can you explain briefly what it is or what it does? JEFF: Sure! It's a set of, really, C Libraries. It's called the Framework. Normally, when you hear framework, you'd think Objective-C framework, but this is all C-level calls. The goal of it is to give us set of functions, a humongous set of functions, that can allow you to do common tasks much faster because they're heavily optimized. As a consequence, that actually saves battery life so you get more power and better energy use. I would even like the case that if you get into it, that your code is actually often better; it's cleaner and it's more maintainable going forward. CHUCK: Huh! What exactly is it used for? JEFF: When you look at the framework, it looks like there are basically 3 areas that it seems to hit which is Audio, Video, and Images, and also Pure Math functions. But, since everything under the hood is all just bits, sometimes, whether it's something is an image or audio or math, it's just that your perspective on things. A lot of times, these functions that are in there can be used for even really mundane tasks that you might not be thinking about them as. You might grab an audio function to do something where you’re simply doing some very simple calculation for something that has nothing to do with audio. CHUCK: Got you! ROD: I would imagine game programming would use a lot especially 3D… JEFF: Oh, sure! Game programming seems like the easiest place to get the most immediate impact from this, but also, Video and Image Processing. Actually,

CHUCK: I’m Charles Max Wood from DevChat.tv.

If you’re interested in that, you can go check it out there. We also have a special guest, and that’s Patrick Burleson. PATRICK: Hello from Dallas, Texas! CHUCK: Do you want to introduce yourself since you haven’t been on the show before? PATRICK: Sure! My name is Patrick Burleson. I run BitBQ software, which is BitBQ.com. I also do quite a bit of consulting with MartianCraft, and also MartianCraft.com – they are the makers of the design application called Briefs. CHUCK: Cool! BEN: That was a previous pick of the show! CHUCK: Yup! PATRICK: Awesome! PETE: We should do an episode about Briefs. PATRICK: You should! I will probably get your wrap on the show. CHUCK: That’d be awesome. Then we could do one on boxers. BEN: Yup, quite a history. PATRICK: Yes, Briefs has a very long history. CHUCK: That’d be really interesting. We brought you on to talk about “Build Automation”. PATRICK: Yeah! Build Automation is something that I think everyone should probably definitely look into even if you’re on a team or even a solo developer. That sounds crazy to some people why would a solo developer want to have a build automation…The way I look at it is, on my solo stuff, I want a computer doing as much of the work as I can make it to without me having to get in the way. Automating your build is one of those things where with a click of a button, I can update and ship a new version of any of my products or ship out a beta or whatever. It makes it very, very easy and also reduces the number of mistakes you can make. You don’t have to do anything manually; there’s a chance for a mistake. CHUCK: So it’s just kind of like continuous integration? PATRICK: Yeah, it is a lot like continuous integration. You can use it 2 different ways.

I’m not a robot; I’m just going to [unclear] [Laughter] CHUCK: Ben Scheirman. BEN: Hello! I’m eagerly waiting of the arrival of GTA 5. So if the doorbell rings, I may run to go get it. CHUCK: Alright! Jaim Zuber. JAIM: Hello from Minneapolis! And also, not a robot. CHUCK: Pete Hodgson. PETE: Good morning from…I am not a robot. [Laughter] CHUCK: Rod Schmidt. ROD: Hello from Salt Lake! CHUCK: I’m Charles Max Wood from DevChat.tv. Before I introduce our guest, I just want to make a real quick announcement. This Friday, meaning last Friday when you get this episode, was my ‘Freedom Day’. It was the day I was laid off from my job 3 years ago and went freelance. I’m celebrating that by putting up a free video that kind of chronicles my journey through freelancing and going from laid off to actually making enough money to live on. I’m going to have a lot of lessons that I learned in there and stuff, so if you’re interested, you can get that at GoingRogueVideo.com. BEN: Whoo-hoo! Congrats! CHUCK: Thanks! We also have a special guest, and that is Steve Madsen. STEVE: Hello from the Columbus, Ohio. CHUCK: Can we get you to introduce yourself real quick? STEVE: Sure! I own Light Year Software, which is a small consultancy here in Columbus specializing in Rails and iOS development. I’ve been doing that for about 7 years now since relocating back from the San Francisco Bay Area. CHUCK: Was it named after the unit of measure, or the cartoon character? STEVE: Unit of measure. CHUCK: Okay. STEVE: I was looking for something science-y. CHUCK: Awesome. PETE: What’s the cartoon character? CHUCK: Toy Story. Buzz Lightyear. PETE: Oh! Oh, yeah. CHUCK: Alright, we brought you on to talk about “Networking”. STEVE: Yes! That’s a big topic! CHUCK: I was going to say [laughs] it was kind of a broad topic. What in particular is interesting about networking with iOS or Cocoa? STEVE: Specifically about iOS, obviously, we’re talking about mobile devices. I think it’s safe to say that since mobile devices became as popular as they did with the introduction of the iPhone, the possibilities on how for us to build apps that communicate back to servers or communicate with people nearby have gone up a lot. CHUCK: Yeah, that makes sense.

This week on our panel, we have Ben Scheirman. BEN: Happy Apple Christmas Day! And hello! CHUCK: Apple Christmas Day… BEN: Yeah! Today is the launch date.

CHUCK: I’m Charles Max Wood from DevChat.tv. We have a special guest, and that’s Aaron Douglas. AARON: Hey! How’s it going? I’m saying hi from Milwaukee, Wisconsin. CHUCK: Pete would be so proud of me, I didn’t butch your name. AARON: [Laughs] CHUCK: We have you on this week to talk about “Scalable Cloud Apps”. AARON: Yeah, definitely. CHUCK: I asked you before the show, I’m going to ask you again, how does that relate to iOS programming? AARON: I’ve noticed that a lot of us iOS devs come from more of the finite programming that we know – JavaScript and CSS – it’s just this kind of a logical step into iOS app development. I came from a Java enterprise background so I’m very familiar with writing apps that are behind other apps. I noticed that a lot of iOS developers are afraid of integrating their app with a server, and that there’s a lot of apps that have to talk to other users or there’s central data. So I think it’s a really important topic just because apps can be so much more powerful if they are connected with other people. CHUCK: Absolutely. Are you talking about API services like Facebook or Twitter? Or, are you talking about more of the backend systems like Parse? AARON: Yeah, it’s more of the backend systems like Parse.

PETE: My boy is teething at the moment, and we got up today at 5 o’clock in the morning. That’s nice. CHUCK: [Laughs] CHUCK: Hey everybody and welcome to Episode 20 of iPhreaks! This week on our panel, we have Pete Hodgson. PETE: Good morning from San Francisco! CHUCK: I’m Charles Max Wood from DevChat.tv. We have a special guest, and that’s Jason…is it Felice? JASON: Yeah, it’s Felice, that’s right. Hello from Detroit this time! CHUCK: I do that just to make Pete laugh. PETE: [Laughs] Yeah, it makes me laugh, I freaked out. [Laughs] Oh, I was going to say like you did the episode number, and I was like thinking, “Should I remind him? Because I don’t remind him, I’d keep him say anything.” [Laughs] CHUCK: No, I was seriously actually thinking, “I should ask Jason just to make sure I know how to say his last name,” and I was like, “Nope! I’m going to do this just for Pete.” JASON: [Laughs] PETE: Oh, man. Well, I’m touched. Thank you very much. CHUCK: So Jason, since you’re new to the show, do you want to introduce yourself really quickly? JASON: Sure! That’s probably the hardest question. I have been doing mobile development for, I don’t know, it’s like 3 years or something like that, but it really depends on what you count. I’ve done some of embedded development before that, and some dust wholesome stuff back in the day, something like ’90 something. And mostly, I’ve been on the next person, which is why I found first to home with iPhone stuff, and I’ve done some Android. I think the bigger focus that I have is on creating expressive beautiful code and helping people to do that because I think a lot of people just haven’t been exposed to really expressive code especially when we’re talking mobile environment. PETE: What do you mean by expressive code? This is a good sidebar conversation we can talk about. I’m interested particularly in expressive code in Objective C [laughs]. It’s an interesting language for that kind of stuff I think. JASON: It is, yes. And that brings up an interesting question, which is like ‘how much of the language you have to know before code is expressive?’ Because everybody that I have actually worked with are brought into Objective C into them, like for first couple of weeks, group of programmers who weren’t familiar with it. Like my first 2 weeks, they’re just like, “I don’t even see code. It just looks like ASCII. I’m not even sure what’s going on either.” CHUCK: [Laughs] JASON: That’s the response that I’ve got. And it’s interesting because after a week or 2, they’re like, “Oh, okay! Got it!” I think it has to do with the [unclear] versus the indentation, the way that it uses it being different from most of the languages. PETE: Yeah. JASON: But I’ve seen Kiwi who makes nice expressive tests for the most part that’s sort of the DSL approach.

Transcript CHUCK: Hey everybody and welcome to Episode 18 of The iPhreaks Show! This week on our panel, we have Pete Hodgson. PETE: Hello from San Francisco! I can’t think of anything funny to say. CHUCK: Andrew Madsen. ANDREW: Hi from Salt Lake City! CHUCK: Ben Scheirman. BEN: Hello from Houston! CHUCK: Jaim Zuber. JAIM: Hello from Minneapolis! CHUCK: Rod Schmidt. ROD: Hello from Salt Lake! CHUCK: I’m Charles Max Wood from DevChat.tv. This week, we have a special guest, and that’s Ken, is it Auer? KEN: That’s correct! And I’m in Holly Springs, North Carolina. CHUCK: Awesome. We brought you on the show today to talk about “Software Craftsmanship”. KEN: Good! That’s what I came for! CHUCK: Oh, good! BEN: You mean cowboy coding? CHUCK: [Laughs] Cowboy coding… KEN: Not at all. CHUCK: [Laughs] Don’t make him get his gun. BEN: [Chuckles] CHUCK: Do you want to just explain what Software Craftsmanship is? KEN: In a nutshell, I would say caring about the craft and what you’re doing and how you’re building yourself with. I tend to come from the school that Software Craftsmanship as opposed to the people who software craftsman and impress other people [unclear]. CHUCK: [Laughs] I like that. I know a lot of the latter. I know a few other former, too. I’ve talked to few people about Software Craftsmanship before. The one that comes to mind first off is Micah Martin who’s Uncle Bob’s son over at 8th Light. When I talked to him, he actually mentioned the Manifesto for Software Craftsmanship. Is that something that you try and stand by? And, is there a lot of culture and (I’m trying to think of what the right word is), sort of like the Agile Manifesto where there’s all of this extra stuff around it. Does the Software Craftsmanship kind of have that as well? KEN: I think, what are in the Software Craftsmanship Manifesto, if I understand it right because I wasn’t there when they put it up, it’s really just about software people that are often just get them treated like mushrooms; shelved in the dark in the corner if they don’t, and hopefully they go out. The whole idea was, “This is something that we should be proud of and do well.

Software Craftsmanship with Ken Auer
Transcript [This show is sponsored by The Pragmatic Studio. The Pragmatic Studio has been teaching iOS development since November of 2008. They have a 4-day hands-on course where you'll learn all the tools, APIs, and techniques to build iOS Apps with confidence and understand how all the pieces fit together. They have two courses coming up: the first one is in July, from the 22nd - 25th, in Western Virginia, and you can get early registration up through June 21st; you can also sign up for their August course, and that's August 26th - 29th in Denver, Colorado, and you can get early registration through July 26th. If you want a private course for teams of 5 developers or more, you can also sign up on their website at pragmaticstudio.com.] CHUCK: Hey everybody and welcome to Episode 17 of The iPhreaks Show! This week on our panel, we have Pete Hodgson. PETE: Hello, hello from San Francisco! CHUCK: Jaim Zuber. JAIM: Hello from Minneapolis! CHUCK: Andrew Madsen. ANDREW: Hi from Salt Lake City! CHUCK: Rod Schimdt. ROD: Hello, hello from Salt Lake! CHUCK: I’m Charles Max Wood from DevChat.tv. This week we have a special guest, and that is Brandon Alexander. BRANDON: Hello! I’m coming from Atlanta, Georgia. CHUCK: Since you haven’t been on the show before, do you want to give us a brief introduction, let us know who you are? BRANDON: I’m currently a iOS and hopefully Mac developer for Black Pixel. I do a lot of the client development work and test as much as I can a lot of our products. I’m also an author, a conference speaker, and I’ve also done a training video to appear soon. CHUCK: Nice! Sounds like fun! What book did you write? I’m curious… BRANDON: The book I wrote is called “Pro iOS 5 Tools”. It’s a couple of versions of iOS old, but the techniques in the book are still completely valid today. CHUCK: Very nice. Alright, we’ll tell people to go check it out. We brought you on the show to talk about “Performance Tuning” for your iOS app. I think it’s interesting; we’re talking about a resource-constrained environment. Is it about the user’s experience? Or, are there other concerns as well that we’re trying to optimize for? BRANDON: Ultimately, it’s about the user experience. If you try to implement something and the user doesn’t have a good experience with it, or it does something over the phone like battery life, you might want to rethink that feature or rethink the assumptions of your application.
