Well blocking IO means that a given thread cannot do anything more until the IO is fully received (in the case of sockets this wait could be a long time). Non-blocking IO means an IO request is queued straight away and the function returns. The actual IO is then processed at some later point by … Read more
If you are using Google Tag Manager and also want to trigger some events via code, ga(‘send’…) does not appear to be enough. You need to first fetch the appropriate analytics object: if (“ga” in window) { tracker = ga.getAll()[0]; if (tracker) tracker.send(“event”, “Test”, “Test GA”); } Note that this assumes you’re only using a … Read more
Solved: A shortest scrollbar click detection I could come up with, tested on IE, Firefox, Chrome. var clickedOnScrollbar = function(mouseX){ if( $(window).outerWidth() <= mouseX ){ return true; } } $(document).mousedown(function(e){ if( clickedOnScrollbar(e.clientX) ){ alert(“clicked on scrollbar”); } }); Working example: https://jsfiddle.net/s6mho19z/
Update (February 2021) Several solutions seem to be accepted on Github, whereas my original answer is not. I’m rounding them up here for convenience: Solution 1a (see Engin Yapici’s answer below): v-on=”enableClick ? { click: clickHandler } : {}” Solution 1b (see Heals Legodi’s answer below): v-on=”enableClick ? { click: () => clickHandler(params) } : … Read more
Events in general: Events are always sent to inform about something (e.g. a change of state). Let’s take your example with a man and a wall. Here we can imagine that there is a game where a user can walk as a man in a labyrinth. Every time a user hits the wall it should … Read more
Pre/PostBuildEvents are properties, so to override them just set them from command line to empty string. msbuild foo.sln /p:PreBuildEvent= /p:PostBuildEvent=
The reactor pattern is more specific than “event driven programming”. It is a specific implementation technique used when doing event driven programming. However, the term is not used with much accuracy in typical conversation, so you should be careful about using it and expecting your audience to understand you, and you should be careful in … Read more
The Observer Pattern is a very special instance. Event-Driven can mean anything. In most Observer Pattern implementations the Observer is an object watching the observee. When the observee is changed, a method of the observer is called. Strictly speaking this is not an “Event”. That means: various different actions on the observee, usually lead to … Read more
Commands can be rejected. Events have happened. This is probably the most important reason. In an event-driven architecture, there can be no question that an event raised represents something that has happened. Now, because Commands are something we want to happen, and Events are something that has happened, we should be using different verbs when … Read more
Here is a Typesafe/Reactive point of view on the question from Jonas Bonér. From the third paragraph of this blog post: The difference being that messages are directed, events are not — a message has a clear addressable recipient while an event just happen for others (0-N) to observe it.
