Created November 7, 2013 10:41 — forked from alexjs/cors-nginx.conf
#
# Slightly tighter CORS config for nginx
#
# A modification of https://gist.github.com/1064640/ to include a white-list of URLs
#
# Despite the W3C guidance suggesting that a list of origins can be passed as part of
# Access-Control-Allow-Origin headers, several browsers (well, at least Firefox)
# don't seem to play nicely with this.

ilguzin / socket_idle_timeout.java
Created June 5, 2013 08:44
The way to organize read timeout (read idle timeout) for socket connection with Netty. See. http://docs.jboss.org/netty/3.2/api/org/jboss/netty/handler/timeout/ReadTimeoutHandler.html
public class MyPipelineFactory implements ChannelPipelineFactory {
private final Timer timer;
private final ChannelHandler timeoutHandler;
public MyPipelineFactory(Timer timer) {
this.timer = timer;
this.timeoutHandler = new ReadTimeoutHandler(timer, 30), // timer must be shared.

ilguzin / implicits_create_and_import.scala
Created April 12, 2013 07:12
Useful way of injecting implicits in the scope. We add here a companion object with implicits for mongo database requests. Then make the object nested in the desired class by importing.
object UserDaoImpl {
object Implicits {
implicit object AccountWriter extends BSONDocumentWriter[Account] {
def write(acc: Account) = BSONDocument(
"email" -> acc.email)
}
implicit object AccountReader extends BSONDocumentReader[Account] {

ilguzin / mongo_unique_index_on_embedded_document
Last active December 16, 2015 02:59
As comes from official mongo documentation you cannot create unique index on fields from embedded documents. Here is a workaround for those using $push to append values to array of embedded documents.
Mongo shell command
> db.users.update(
{ community:'Coomunity1',
'users.login': {'$ne': 'Login1'}
},
{ $push:
{ users: {login:'Login1', pwd:'*****'} }
},
{upsert: true})

ilguzin / scala_implicit_list_conversion
Last active December 16, 2015 00:38
Implicit conversions to work inside collections. Stolen from http://stackoverflow.com/questions/12447968/how-can-i-get-implicit-conversions-to-work-inside-collections
Here are a few alternatives you might wish to consider:
1. Use a view bound
If it's possible to change the function that takes a List of Bs, this would be the simplest solution. Modify it to accept a List of things that can be converted to Bs. That is,
def myfun(l: List[B]) = ...
would become
def myfun[X <% B](l: List[X]) = ...
