This blog post describes a new setup for presenting with Apple’s Keynote app that I’ve experimented with. It involves: A Mac running Keynote An iOS device (iPhone or iMac) The wish For presentations, mirroring the laptop’s display with the projector’s is perfect, because: It is easy to do interactive demos (e.g. switch to a REPL, run some JavaScript code). You can use the cursor as a virtual laser pointer (there is a preference under “Slideshow” to show the cursor in that mode). But there are several pieces of information that would be nice to have while presenting: The next slide, for smoother segues Remaining time (countdown) Presenter notes (I don’t use them, but many people do) Therefore, many people don’t mirror displays and Keynote’s Presenter Display. But then you lose the previously mentioned advantages. The best of both worlds It’d be cool to have mirroring plus extra information displayed somewhere, but I don’t even know how exactly that would work. Non-solution: Keynote Remo...

There is one important area where Android and Windows 8 are ahead of iOS: sharing data between applications [1] . Interestingly the foundations for improving things have already been laid. There are two parts when it comes to sharing: offering data and receiving data. The offering part already exists [2] : many apps have a “sharing” button. For example, things that can be done with the current page in Safari include: Create a bookmark, send the URL via email, tweet the URL. Sharing in Safari on an iPhone However, the receiving part is still limited. iOS has built-in support for email, Twitter and more, but you can’t plug into the system with your own app. That is likely to change soon, as explained in a tweet by @chpwn: New, private iOS 6 feature Apple is using: remote view controllers. For example: the Mail compose view is now run in a separate process. Consult [3] for details. I can’t wait for Dropbox to be a sharing plugin, then you can send files to it from everywhere and from i...

Today, Nokia introduced a new brand for its location and mapping services: HERE. HERE applications will be available for several operating systems: iOS: based on HTML5(!), with an offline mode, voice-guided turn-by-turn navigation (including for walking) and public transport directions. Free, available within a few weeks. Firefox OS: Nokia has announced a strategic partnership with Mozilla and will bring a HERE app to Firefox OS sometime in 2013. Android: Nokia demonstrated a “reference application” and an SDK that will be available for Android OEMs in early 2013. To better compete with Google and Apple, Nokia is in the process of acquiring the company earthmine whose technology would help with bringing 3D mapping to HERE. Furthermore, Nokia announced LiveSight a brand for technologies (present and future) for augmented reality. For example, in one envisioned LiveSight application, you would look at your surroundings through your phone’s display and l...
