similar to: Real-time events with WebSockets and fallbacks?

I''m in the midst of a few new Rails deployments as well as being tasked to revise an existing older deployment to help improve performance. So, I''m wondering what sort of setup is preferable these days for a dedicated server? The basics I''m aiming to start with are the latest CentOS/RHEL, PostgreSQL, Ruby 2.x, Rails and Apache. Is Passenger still the way to go these

I want to connect each llvm ir for example: 1. Turn C/C++ language into C_llvmIR assembly language using Clang 2. Turn Fortran language into Fortran_llvmIR assembly language using Dragonegg 3. Turn Python language into Python_llvmIR assembly language using Unladen-Swallow 4. Connect each llvm IR Is this possible? Wonjun, Choi -------------- next part -------------- An HTML attachment was

I''m thinking of starting on a Ruby website that uses WebSockets, and perhaps working some on a server for it beforehand. Is good support for asynchronous connections something I could work on adding to the Rails core? Is it feasible? Desired? As I understand it, Rails plugins like Juggernaut [1] aren''t going to optimally support async, since they can''t re-architecture

Hi all, I can't find a working archive search for this list, so please forgive me if this has been discussed before. Has any thought been given to supporting websockets in the ssh client? I'm talking about solely using a websocket as the transport layer, and leaving the actual protocol intact, as opposed to the (to me, frankly terrifying) idea of allowing a web server to act as an ssh

Hi everyone, I'm currently trying to play a little with WebRTC using sipml5 client and Asterisk trunk (370821) It seems the the WebRTC implementation for Asterisk 11 is already available in the trunk? Am I right? http://lists.digium.com/pipermail/asterisk-dev/2012-July/055940.html I'm having trouble to even register to my Asterisk server using sipml5 client. The only reference to

I have heard alot about Node.js and watched a few tutorials and read some stuff. I get the impression that in certain situations AJAX calls with node.js is alot faster than with rails. I also have somewhat of an impression that with Rails web sockets are complicated to implement but with node.js web sockets might be alot easier. I am trying to figure out if I should learn some node.js or

I'm trying to generate the correct response to a websocket connect. The websocket connect is: GET /chat HTTP/1.1 Host: example.com:8000 Upgrade: websocket Connection: Upgrade Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ== Sec-WebSocket-Version: 13 So I take the Sec-WebSocket-Key above and add the extra part and put that in /tmp/sha1 dGhlIHNhbXBsZSBub25jZQ==258EAFA5-E914-47DA-95CA-C5AB0DC85B11

I finally found it. echo -n ${key}258EAFA5-E914-47DA-95CA-C5AB0DC85B11|openssl dgst -sha1 -binary|base64 Thanks, Jerry
