RavenDB 3.5 Features: Data Exploration

AddThis Social Bookmark Button
RavenDB is doing a pretty great job for being a production database, in fact, we have designed it upfront to only have features that make sense to have for robust production systems. In particular, we don’t have any form of ad-hoc queries. A query always hits an index, so it is very fast. Even what we call dynamic queries in RavenDB are actually creating an index behind the scene. This is pretty awesome for normal production usage, but it does have some limitations when you want to explore the data. This can be because you are a developer trying to
find a particular something, and you just want to quickly fire off random queries. You don’t care about the costs, and you don’t want to generate indexes. Or you can be an admin that needs to get a particular report from the system and you want to play around with the details until you get everything right. In order to serve those needs, RavenDB 3.5 is going to have a really nice feature, explicit data exploration. For example, let us say that I want to count the number of unique words in all of my posts, I can do...(Read whole news on source site)

I’m Not Mocking You, Just Your AngularJS Tests

You could alternatively call this post, “Avoid redundancy in your Angular unit tests.” There are myriad approaches to implementing service calls in Angular. Some developers use the $resource service for pure REST endpoints. I prefer to isolate web interactions in a component of their own that returns a promise. Although $http returns a promise, you have to know how to parse the pieces, such as looking at the data property instead of the result itself, so I prefer to wrap it. A service in my apps ends up looking something like this: var blogExample; (function (blogExample) { ... [[ This is a content summary

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:
