How to improve performance of ngRepeat over a huge dataset (angular.js)?
I have a huge dataset of several thousand rows with around 10 fields each, about 2MBs of data. I need to display it in the browser. Most straightforward approach (fetch data, put it into $scope, let ng-repeat="" do its job) works fine, but it freezes the browser for about half of a minute when it starts inserting nodes into DOM.

How to use Jackson to deserialise an array of objects
The Jackson data binding documentation indicates that Jackson supports deserialising "Arrays of all supported types" but I can't figure out the exact syntax for this. For a single object I would do this: //json input { "id" : "junk", "stuff" : "things" } //Java MyClass instance = objectMapper.readValue(json, MyClass.class); Now for an array I want to do this: //json input [{ "id" : "junk", "stuff"
AngularJS - How to use $routeParams in generating the templateUrl?

AngularJS - Any way for $http.post to send request parameters instead of JSON?
I have some old code that is making an AJAX POST request through jQuery's post method and looks something like this: $.post("/foo/bar", requestData, function(responseData) { //do stuff with response } requestData is just a javascript object with some basic string properties. I'm in the process of moving our stuff over to use Angular, and I want to replace this call with $http.post. I came up with
How to decode JSON with type convert from string to float64
I need to decode a JSON string with the float number like: {"name":"Galaxy Nexus", "price":"3460.00"} I use the Golang code below: package main import ( "encoding/json" "fmt" ) type Product struct { Name string Price float64 } func main() { s := `{"name":"Galaxy Nexus", "price":"3460.00"}` var pro Product err := json.Unmarshal([]byte(s), &pro) if err == nil { fmt.Printf("%+v\n", pro) } else { fmt.
Gson: Directly convert String to JsonObject (no POJO)
Can't seem to figure this out. I'm attempting JSON tree manipulation in GSON, but I have a case where I do not know or have a POJO to convert a string into, prior to converting to JsonObject. Is there a way to go directly from a String to JsonObject? I've tried the following (Scala syntax): val gson = (new GsonBuilder).create val a: JsonObject = gson.toJsonTree("""{ "a": "A", "b": true }""").getAs
