Microsoft Build 2015: We’re there, come say hi!

AddThis Social Bookmark Button
All of a sudden it seems, Microsoft Build is again upon us. And what a Build it promises to be. Let’s see what’s been promised, or, even better, what’s been conjectured. 1. Visual Studio 2015. OK, it seems fairly clear by now that at a Microsoft developers’ conference called Build, Microsoft are going to announce a new build (geddit?) of Visual Studio 2015. I doubt it’ll be the RTM but instead the RC, or Release Candidate. That’ll make it high time for this software-risk-averse CTO to install it on his machine – virtual machines, what are they? 2.
Windows 10. No, definitely not the release, but I dare say there’ll be some kind of developer-related news about the next generation of the Windows platform. There may be another beta release, but then again Microsoft are throwing out new versions regularly already. 3. Developing cross-platform Windows apps. With the previous two items, we’ll be hearing about the ins and outs of creating cross-platform apps. Maybe with some joint time with Xamarin (after all, they are there too). So expect lots of information about Universal apps, especially for the phone. Maybe even for IoT? Who knows. (Well, they do,...(Read whole news on source site)

ReactiveCocoa 3.0 - Signal Producers and API clarity

AddThis Social Bookmark Button
My previous blog post took a first look at ReactiveCocoa 3.0 (RC3), where I described the new Signal interface, and the pipe forward operator. In this blog post I continue my exploration of the RC3 APIs and turn my attention to signal producers. I also discuss a few points around the overall clarity of the new ReactiveCocoa APIs. If you’ve used ReactiveCocoa before you might have come across the concept of hot and cold signals. The distinction between the two has been a source of confusion, partly because the two concepts are represented by the same type, RACSignal. The ReactiveCocoa
design guidelines recommend naming conventions for distinguishing between hot and cold signals, however they are pretty subtle! With RC3 the difference between these two concepts is made much more explicit by representing each with a different type (Signal and SignalProducer), and a subtle difference in operation naming (you observe a signal but start a signal producer). With RC3 the confusing terms ‘hot’ and ‘cold’ have disappeared completely. Signals The easiest way to understand how Signal and SignalProducer compare is to give them a try. In my previous blog post I created a simple signal that emits a next event each second:

Setting up a VPN server on a Mac and using it for #Xamarin.iOS development

When you develop for Xamarin.iOS, you are faced with the annoying fact that you have to use a Mac to build and debug your iOS applications. There are of course no technical reasons behind this requirement, it’s just Apple being Apple and forcing their hardware on every iOS developer (one can wonder how loud people […]

Windows 10 build 10061 fixes MapIcon woes!

I discovered this while preparing for my Techdays 2015 talk and you probably have to be a mapping nut like me to appreciate this fully, but some things cannot wait until my session itself, so here’s this thing I found out while pressed a dot after a MapIcon type variable after having upgraded to Windows 10 build 10061. Windows Phone 8.1 brought an awesome new map control that introduced the concept of MapIcon. Previously, if you had to draw point objects on a map depicted by an image, you had to resort to drawing
XAML elements on top of the map. While the map itself took care of the position of the icon, behind the scenes it was not the map, but the UI thread taking care of drawing the icons, which is quite resource-heavy as anyone who has tried to draw a lot of points on a Windows Phone map will acknowledge. This resulted also in the icons lagging visibly behind when you change position, something you (unfortunately) can see very good when you use my Sensorcore app Travalyzer. Enter Windows Phone 8.1, that introduced the MapIcon – a...(Read whole news on source site)

does it hurt when you stop?

Hold your cell phone up to your face, like you’re talking to someone… keep it there for 20 or 30 minutes, constantly holding your arm tight as you do. When you finally decide to put the phone down, your arm is going to be tired and sore. It’s going to hurt just to put the […]
