Start Developing iOS Apps Today: Introduction

Start Developing iOS Apps Today: Introduction
Start Developing iOS Apps Today is the perfect starting point for creating apps that run on iPad, iPhone, and iPod touch. View this guide’s four short modules as a gentle introduction to building your first app—including the tools you need and the major concepts and best practices that will ease your path. The first three modules end with a tutorial, where you’ll implement what you’ve learned. At the end of the last tutorial, you’ll have created a simple to-do list app. After you build your first app and before you start your next endeavor, read the fourth module. Even though it takes you through every step of building a simple app, to benefit most from this guide, it helps to be acquainted with computer programming in general and with object-oriented programming in particular. Get the Tools Before you start developing great apps, set up a development environment to work in and make sure you have the right tools. To develop iOS apps, you need: To download the latest version of Xcode Related:  Code

Sparse files – what, why, and how « UNIX Administratosphere Sparse files are basically just like any other file except that blocks that only contain zeros (i.e., nothing) are not actually stored on disk. This means you can have an apparently 16G file – with 16G of “data” – only taking up 1G of space on disk. This can be particularly useful in situations where the full disk may never be completely used. One such situation would be virtual machines. If a virtual machine never fills the disk entirely, then a certain amount of the disk will never have anything but zeros in it – permitting the saving of disk space by using a sparse file. The operating system (which supports sparse files) knows that the block “exists” but is null, so it provides the zero-filled block out of thin air. There are problems with using sparse files. Another problem is that everything about disk management is based on how many sectors or blocks are used – and the disk size reported for a sparse file is the full size of the file (not the actual number of blocks on disk).

Introduction to HTML - Web developer guide When you look at a web page in a web browser, you see, at the simplest level, words. These words usually have some style characteristics, such as different fonts, font sizes and colors. In many cases a page also displays images or maybe video. Sometimes there is a form where you can enter (or search) for information, or customize the display of the page to your liking. Often a page contains content that moves or changes while the rest of the page remains the same. Several technologies (such as CSS, JavaScript, Flash, AJAX, JSON) can be used to define the elements of a web page. The HTML specification defines a single language that can be written using the relaxed HTML syntax, but also the more strict XML (Extensible Markup Language) one, and also addresses the needs of web applications. The creator of a web page can use Cascading style sheets (CSS) to define the appearance and layout of texts and other materials. This article provides an introduction to HTML. A brief history of HTML <!

Nick Farina - An iOS Developer Takes on Android Recently, we released the Android version of Meridian, our platform for building location-based apps. We didn’t use one of these “Cross Platform!” tools like Titanium. We decided it was important to keep the native stuff native, and to respect each platform’s conventions as much as possible. Now, our platform leverages HTML5 (buzzword, sorry) in many places for branding and content display, so we got a fair amount of UI for free. So, we rolled up our sleeves, downloaded the Android SDK, and got to work. Development Environment Apple has made it pretty easy to start writing iOS apps. Android is a bit more involved. If you want to waste a week or so playing around and not getting work done, you could explore the many tempting alternatives to writing Java in Eclipse. But let’s assume you are on a deadline and want to do things the way that Google endorses. You’re going to just hate Eclipse. Eclipse is a world unto itself. The Java Language Java is a high level programming language. Debugging

Harvard Researchers Build $10 Robot That Can Teach Kids to Code Mike Rubenstein, Harvard University Mike Rubenstein wants to put robots in the classroom. Working with two other researchers at Harvard University, Rubenstein recently created what they call AERobot, a bot that can help teach programming and artificial intelligence to middle school kids and high schoolers. That may seem like a rather expensive luxury for most schools, but it’s not. The tool is part of a widespread effort to teach programming and other computer skills to more children, at earlier stages. Rubenstein’s project grew out of the 2014 AFRON Challenge, held back in January, which called for researchers to design low-cost robotic systems for education in the developing world. He and his colleagues assembled most of the electronics with a pick-and-place machine—a machine that automatically builds printed circuit boards—and in order to further cut costs, they used vibration motors for locomotion and left out a chassis.

Chosen - a javascript plug-in for jQuery and Prototype - makes select boxes better Chosen is a jQuery plugin that makes long, unwieldy select boxes much more user-friendly. Downloads Project Source Contribute Standard Select Turns This Into This Multiple Select <optgroup> Support Single Select with Groups Multiple Select with Groups Selected and Disabled Support Chosen automatically highlights selected options and removes disabled options. Single Select Multiple Select Hide Search on Single Select The disable_search_threshold option can be specified to hide the search input on single selects if there are n or fewer options. Default Text Support Chosen automatically sets the default field text ("Choose a country...") by reading the select element's data-placeholder value. Note: on single selects, the first element is assumed to be selected by the browser. No Results Text Support Setting the "No results" search text is as easy as passing an option when you create Chosen: Limit Selected Options in Multiselect You can easily limit how many options the user can select: Right to Left Support

Apprendre à écrire ou à coder ? Programmer ou être programmé(e) ? Premier argument en faveur de l’apprentissage du code informatique lors de la scolarité : Syntec Numérique, le syndicat qui regroupe les entreprises du secteur, alerte les pouvoirs publics depuis des années sur les difficultés de recrutement d‘informaticiens correspondant à leurs besoins. L’émergence de structures éducatives hybrides illustre le décalage (ou «mismatch») entre formation et profils recherchés, à l’image de l’école 42, une école d’informatique gratuite ouverte à toutes les personnes âgées de 18 à 30 ans, sans condition de diplômes préalables, lancée à l’initiative du PDG de Free en France. 40 000 candidatures ont été reçues en seulement quelques semaines pour 1 000 admis. D’autre part, la vie des individus, des collectivités comme des entreprises est de plus en plus régie par des algorithmes et des programmes informatiques dont la logique détermine une certaine façon de penser. Apprendre à coder dès le primaire… Exemple d’écriture cursive.
