Beginner’s Guide to iOS Development: Building Your First App – Part II In the first part of our iOS tutorial I took you through a guided tour of the iPhone app development. We got a deeper look at Xcode 4, and also took a very short tutorial on building iPhone app. The beginner tutorial was written for anyone who is looking to get into programming iOS apps. Today, we’ll get into the second segment of the topic, where we will be building a fully-functioning iPhone application. At the end of the tutorial you will get an application which can’t be pushed into the iPhone since it will need you to purchase developer program, but we can run it inside the iOS Simulator on a Mac OS X system. Note: You will need a computer with Macintosh Operating System (Mac OS) for Xcode installation, application development and app submission, there’s no way you can do it on Windows legally. Pre-Setup: Installing Xcode Packages If you haven’t done so already you will need to get Xcode 4 on your computer. 1. Hit “Next” and you’ve got to enter a name for your project. 2. 3. 4. 5.

You’ll never believe how LinkedIn built its new iPad app (exclusive) Guess how much of LinkedIn’s new iPad app is actually mobile web and not native. Go ahead — guess. We’ve had a lot of fun asking people to guess this over the past couple days. They’ll start with 40 percent and edge up to 70 percent, but no one comes close to the real figure: 95 percent. Yes, only one screen in the entire LinkedIn iPad app is actually native. We were shocked to hear this 95-percent figure from Kiran Prasad, who heads up LinkedIn’s mobile development team. But the new iPad app had struck us as so surprisingly sexy during our initial review that we had to know more about how Prasad and his team of four (yep, just four devs built this app) packed so much punch into a web app for a tablet. Especially as Silicon Valley tech companies pick sides in the web-versus-native war, it’s fascinating to see the presumably conservative LinkedIn lean toward the more progressive side of mobile technology. LinkedIn and the mobile web [vb_gallery id=421649] Now, with more Node.js

50 tips for designing brilliant iOS apps | Feature | Computer Arts 1 A touchscreen interface might be flexible and intuitive, but it’s not perfect. Consider what people are doing while they’re using your app, and how they’re holding the device. Remember that fingers cover a much greater area than you might expect, and are far from accurate at selecting items. 2 Take a device-centric approach to design: don’t just think about the size of the screen, but also where and when it will be used. 3 Think of your app one screen at a time. 4 Designing for a mobile phone or tablet is very different from the web, or even a standard desktop app – every element has a fixed position on screen, which must be considered carefully. 5 When porting an app between different screen sizes, bear in mind that when this changes significantly – from iPhone to iPad, for instance – the way in which the device is used will also change. 7 A finger is considerably larger and less precise than a mouse, and touch-targets on a touchscreen interface should leave ample margin for error.
How to write your first BlackBerry application – Lesson 1: UI fields This article is the first in a series of articles about BlackBerry development. With App World, third party software vendors and the web, there are a ton of opportunities for an independent developer to make money. BlackBerry Development in Java – Lection 1: Basic fields in the User Interface Let’s get right into it. Download the JDE (Java Development Environment) from the BlackBerry website. For advanced features and other APIs you may want to use, you need code-signing keys from RIM. For this introductory application, you don’t need signature keys and the compiled *.cod file can be run on the device (and not only on the simulator). After installation of the JDE, launch it and then click on: 1. Then on the left side in the JDE, you see the Tab Files. 1. That’s how the ‘Files’ should look like on the left side of the screen: The *.java Files: We have two *.java files for our Project. A BlackBerry application always starts with the main() method.

tech blog » Blog Archive » zxcvbn: realistic password strength estimation Over the last few months, I’ve seen a password strength meter on almost every signup form I’ve encountered. Password strength meters are on fire. Here’s a question: does a meter actually help people secure their accounts? It’s less important than other areas of web security, a short sample of which include: Preventing online cracking with throttling or CAPTCHAs.Preventing offline cracking by selecting a suitably slow hash function with user-unique salts.Securing said password hashes. With that disclaimer — yes. These are only the really easy-to-guess passwords. Strength is best measured as entropy, in bits: it’s the number of times a space of possible passwords can be cut in half. This brute-force analysis is accurate for people who choose random sequences of letters, numbers and symbols. As a result, simplistic strength estimation gives bad advice. The table below compares zxcvbn to other meters. A few notes: I took these screenshots on April 3rd, 2012. Installation The model Data Conclusion

The Pitfalls of Open Sourcing Your Startup Free and Open Source Software (FOSS) refers to software whose source code is freely available for modification and redistribution. Typically open source projects tend to have strong communities of programmers, developers and most importantly, uses backing them, and it is this community support which ultimately drives these initiatives to succeed. Open Source Software can be found virtually everywhere, from programming languages like Python, the Mozilla suite of applications, the Git version control system and the largest collaborative project in computer history, the Linux kernel. On the surface, releasing the source code of your startup’s application/service to the general public might seem like a good way to advance one’s startup for a very low price, but in reality there exist a few pitfalls. Moreover, since the code is open source, it is visible to all, which presents a potential threat that a competitor may use it to their advantage. What are your thoughts?

Lithium-based Batteries Information – Battery University Discover why lithium-ion is a superior battery system. Pioneering work of the lithium battery began in 1912 under G.N. Lewis, but it was not until the early 1970s that the first non-rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium batteries followed in the 1980s but the endeavor failed because of instabilities in the metallic lithium used as anode material. Lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest specific energy per weight. The inherent instability of lithium metal, especially during charging, shifted research to a non-metallic solution using lithium ions. Credit for inventing the lithium-cobalt-oxide should go to John B. The key to the superior specific energy is the high cell voltage of 3.60V. In 1994, the cost to manufacture Li-ion in the 18650 cylindrical cell was over US$10 and the capacity was 1,100mAh. Types of Lithium-ion Batteries Last Updated 2015-08-19
