La programmazione nel 2017

Geek   20.07.17  

Un'indagine sull'uso dei linguaggi di programmazione del 2017. Un contenitore di open data per stilare classifiche sullo stato della programmazione in continua evoluzione, dalle app ai desktop, dal web ai server.

This app ranks the popularity of dozens of programming languages. You can filter them by listing only those most relevant to particular sectors, such as "Web" or "embedded programming." Rankings are created by weighting and combining 12 metrics from 10 sources. We offer preset weightings—the default is our IEEE Spectrum ranking—but there are presets for those interested in what's trending or most looked for by employers. Don't like the defaults? Take complete control and create your own ranking by adjusting each metric's weighting yourself. To compare with a previous year's data, click "Add a Comparison" and then click "Edit Ranking," which will give you the option to compare with data from 2014, 2015, or 2016.

Come è cambiato negli anni iOS

Geek   01.07.17  

9To5Mac ripercorre l'evoluzione di iOS, dal 2007 a iOS 10, in attesa della versione stabile di iOS 11.

Introduced alongside the first-generation iPhone in 2007, the then-called iPhone OS was the basis of Apple’s first smartphone and its goal to introduce "a revolutionary product that changes everything."

10 years later, the iOS has evolved just as much as the iPhone hardware has, if not more. Head below as we take a look at the progression of iOS over the years...

When Steve Jobs originally unveiled the iPhone at the Macworld Conference & Expo on January 9, 2007, he proclaimed the iPhone ran "real Mac OS X" and was capable of running "desktop applications." Fast forward a few months and the iPhone operating system had been renamed to just iPhone OS, and thus the introduction of iPhone OS 1.
