Questa procedura è dedicata a tutti gli utilizzatori sui iPhone 4 e 3GS, iPad 1 e 2 e iPod Touch che hanno aggiornato il proprio sistema operativo e che, per diversi motivi, vogliono tornare indietro.

I problemi delle grandi aziende IT è spesso ricercato nel settore sviluppo, tanto che più è grande l’azienda e piu’ si cerca di esternalizzare proprio lo sviluppo. In alcuni casi si cerca di manterenere il controllo sul know-how internalizzando i settori funzionali a scapito del development.

Nel febbraio 2001, in una stazione scistica nel Wasatch Mountains dello Utah, diciassette persone si sono incontrati per parlare, sciare, rilassarsi, e cercare di trovare qualcosa in comune. Ciò che è emerso è stato il Manifesto Agile Software Development.

Perché gli sviluppatori non riescono a stimare di stimare il tempo di produzione?

Questa, come altre domande, sono lo spunto per scrivere un articolo che mi è stato ispirato dopo la lettura di un post di  Ash Moran mentre navigavo per il Patch Space Blog.

This is the italian translation of the article Dear business people, an iOS app actually takes a lot of work!, written by Kent Nguyen. Thanks Kent for giving us permission to publish this translated article.

According to various rumors and mainly based on the statements of Richard Shim (DisplaySearch), the leading provider of display and LG, Samsung and Sharp would started production of Retinal Display for iPad3 with twice the resolution of 2048 × 1536 pixels. The screen will appear the same size as the iPad, 10-inch LCD (not AMOLED) with aspect ratio of 4:3.
Apple could start the commercialization of iPad 3 new generation in the first quarter of , 2012.

HTML(5) Approach
The final technique is something that is emerging now, especially thanks to the great improvements in term of stability and speed introduced by the latest version of iOS for the in-app web views. A couple of good examples of this approach are the Ars Technica app and the Bloomberg Businessweek+ magazine.

Pages Pre-Rendered by images
This technique is heavily used inside the highly interactive magazines published using the Adobe Digital Solutions environment: well known examples are the Condé Nast magazines (Wired is one of the most famous examples).
The way these magazines are implemented starts with the well known suite of Adobe Digital Publishing tools, In Design in primis. These tools are used by many publishers around the world and the latest versions offer the pos sibility to export the project, other than in the ubiquitous pdf format, in a package suited for distribution through iPad.

CORE TEXT RENDERING
Core Text (short: CT) is another of those technologies developed for the Mac and later ported to iOS.
The Core Text framework is dedicated to text layout and font handling. Just to summarize the capabilities of this framework, consider that is at the base of the desktop publishing revolution that made the Mac famous in this professional sector.

The Magazine is a PDF File
You may like it or not, but should your software house be committed to develop a magazine iPad app, the magazine will be with high probability given to you as a PDF file. As there is no way to “escape” from it, at the end you will need to develop your own pdf reader or integrate some free or commercial external library.
