hypertable thrift or swig question - go

I'm very interested in Hypertable DB, and im currently developing a crawler and indexer in Go-lang, unfortunately there's no binding available for the languange. I'm having a difficulties in compiling swig and hypertable c++ client (too many errors) and thrift don't have a working support for go-lang, is there a way to connect directly to hypertable's thriftbroker by straightforward coding from go? or any suggestion to access hypertable from go?
Thanks.

There may not be Thrift support in Go, but it appears there will soon be Go support in Thrift:
https://issues.apache.org/jira/browse/THRIFT-625
It appears that the code from this standalone project has been checked into the trunk of Thrift, and will appear in some future release (maybe version 0.7). One of those two (the development version of Thrift or the standalone project should get you started).

Can lua 5.3 do websockets?

I'm trying to build a very simple websocket client in lua, and I have found a number of libraries, but I have also found a lot of problems with each library.
The biggest problem is that lua 5.3 is the current version, but no libraries seem to work with it.
lua-websockets : will not work on lua 5.3 because of the luabitop dependency
http.websocket : gives me connection resets whenever I try to receive messages, and the documentation is sparse when it comes to building an asynchronous websocket client.
turbolua : looks great but the last update was almost a year ago, it will not build on my Mac and the website (www.turbolua.org) appears to have been hacked.
Am I missing something here?
The library found on github.com/arcapos/luawebsocket works with Lua 5.3.

Using Couchbase Lite (not Couchbase Server) in a Golang application

I'm wondering if anyone has ever tried to use Couchbase Lite (not Couchbase Server) in a Golang application. In other words building it into a Golang binary?
I came across this library Couchbase Lite Core and through a quick read, it looks like the underlying library for Couchbase Lite (I stand corrected)? What I couldn't find though was how to use it.
Has anyone tried to make this work with something like cgo perhaps? I'm looking to build it statically into the application so it doesn't have dependencies when distributed.
Lite Core is the underlying implementation of the upcoming 2.0 version of Couchbase Lite. It's still under development. The intention is to have a common core, with platform and language specific bindings on top.
There is currently no Go implementation I'm aware of. cgo does look like an option. Given the goal of Lite Core being the underlying implementation for all platforms, this seems on its face like a reasonable approach.
If you're interested, there's a GitHub account for community projects at https://github.com/couchbaselabs. If you work on this, it would be great to have it included there.
To see an example of platform integration, take a look at https://github.com/couchbase/couchbase-lite-ios/tree/feature/2.0
I haven't tried embedding Couchbase Lite, but my team and I make extensive use of embedded datastores like BoltDB Assuming you aren't using Couchbase's replication features heavily, BoltDB may meet your requirements.

Xamarin Forms: How do I implement WebSockets?

We want to transfer data from a client to a server in realtime, so we have decided to go with WebSockets.
Using Xamarin.Forms it was surprisingly difficult to find a suitable WebSocket library.
The best match was "WebSocket4Net" because it is directly suggested on Xamarin's Homepage. However I was not able to install this library, because it only supports versions of .NET up to v4.0. (We are using v4.5)
Whenever I try to change the target framework of my PCLs from v4.5 to v4.0 I get loads of weird errors stating "Windows.Input library could not be found", "ObservableCollection could not be found" etc.
So we are currently using the library "WebSocket.Portable.Core", which although lacking some functionality worked out. However for some reason we can only receive one message. The event "MessageReceived" always is just called once.
Has anyone heard about such a problem with WebSockets? Maybe it is just time to use another library, but I just can't find one?
I also can't find any solution how to implement WebSockets natively for each platform.
WebSockets.PCL has a native implementation for each platform and it's well documented

Why one might need JeroMQ if it can use JZMQ?

Simple question. Why "porting" zmq on java and call it JeroMQ is good idea?
JeroMQ is an official project of the ZeroMQ community; it's a full port of the C++ libzmq library, supporting version 3.2.
Advantages:
Pure Java, so no need to link in C/C++ via JNI. This is extremely helpful on devices where native libraries are difficult or impossible.
100% compatible with the JZMQ API (the two projects agreed on a single API so you can import one or the other transparently).
100% compatible with the ZeroMQ wire protocol, so you can run some nodes using JeroMQ and some using the native library, and it works as expected.
Good performance, relatively close to the native library.
Disadvantages:
No PGM multicast - there is no Java version of that library yet.
Does not yet support ZeroMQ v4 functionality, including security.
JeroMQ is a pure Java implementation of ZeroMq. If your target language is Java, it's easier to get started with JeroMq since it uses a single jar file. ZeroMq (zmq), on the other hand, is written in C. You must build zmq, libzmq, and the Java language bindings, jzmq, to use it in a Java app. The JeroMq API is identical to jzmq, so starting with JeroMq and switching to jzmq later has no impact on your application with the exception of performance; zmq performs better than JeroMq.
Hope that helps,

Need a mongo driver that supports replica sets and eventmachine for ruby

I am trying to find a ruby based mongo driver to use in my project. It has to support replicasets and eventmachine. I'm aware of em-mongo, but it does not support replicasets. It looks like there is not a good option at the moment, but I wanted to see if anyone was aware of one before I explore mongo alternatives...
I'm a maintainer for the 10gen Ruby driver. Hang tight, we'll have support for this in the near future.
I don't believe there is anything out there (from 10gen or otherwise) that does this currently but we're actively working on a version of our driver that supports asynchronous reads and writes.
All of the official 10gen drivers are aiming to support this by mid to end of the year and the ruby driver team is already working on it. Hopefully we'll have something for you much earlier than that (likely in our 2.0 release).
You can try my fork of em-mongo with Replica Set support.
Also I am working on gem Monga which should support some modern features of MongoDB. But it is totally not production ready right now.
