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...

Recently, I was shopping for a presenter (a remote control for PowerPoint, Keynote, etc.) and liked the Logitech Presenter R700 (a newer European-only version of the R800) best, due to its design and its integrated display with a countdown. Alas, Macs are not officially supported for this device. Thankfully, they can be made to work together, as explained in this blog post. I also mention how my configuration file can be adapted to an R800. Installation If you press keys on the R700, wireless signals are sent to the R700’s USB stick, which appears to OS X as a USB keyoard. The key presses that OS X receives work for PowerPoint, but not for other apps. Thankfully, a tool called KeyRemap4MacBook lets you remap the keys per app and only for the R700 – without affecting other devices (including the actual keyboard). Based on Andrew Ferrier’s work , I wrote a configuration file that makes the R700 work with Keynote, DVD Player and VLC. Installation: Install KeyRemap4MacBook Copy the file...

I many cases, if you are presenting in front of an audience, you will create slides, visual material of some kind. I’m a very visual person myself and learn much better if I can read in addition to listen. Slides are also helpful when you lose attention for a few seconds. There are a variety of software technologies out there for helping you with creating slides. Following are ones that I find intriguing: PDF: somewhat surprisingly, I still find PDF the best format for slides (I would have expected it to be HTML by now). Why? You get a single, easily portable and printable file that scales well to various screen sizes and resolutions. Furthermore, all modern web browsers have excellent PDF support, which means that you don’t even have to “leave the web” if you want to check out a PDF file. Lastly, Speakerdeck is a convenient way of putting PDF slides online. As examples, you can check out my slides . LaTeX: works remarkably well for slides, via the built-in Beamer packag...
