So, now that machines have as much memory as they do, we have the opportunity to make X11 windows lossless, by a mechanism called redirection. If you need local IP address, use:: The X server acknowledges the XRender request.

To send data back to a specific client, you first send the handle, and then the data, as two frames. Often, the resource corresponds to a file or the output of an executable residing on the server. I have made extensive references to information, related to Ruby, available in the public domain wikis and the blogs, articles of various Ruby Gurusmy acknowledgment and thanks to all of them.

They could, if they wanted to, draw the window pixmaps onto the COW normally. A large reason that the X Window System stuck around for now was just because it was a lot of effort to replace it.

I also want to give a big shout-out to everybody who worked on the stuff I mentioned in this article, and also want to give my personal thanks to Owen Taylor, Ray Strode and Adam Jackson for being extremely patient and answering all my dumb questions, and to Dave Airlie and Adam Jackson for helping me technically review this article.

MQTT on Google Groups — this is mostly where discussion of the protocol itself happen, along with the broader ecosystem of implementations and use cases. Only listed in here for completeness, and as an introduction. Much of the material on rubylearning.

Hence, a machine can have a maximum of port numbers ranging from 0 to And if you want to help out in any of these areas, I assume all the projects listed above would be more than happy to have contributions. Intel supports Mesa and has built a number of drivers for their chipsets which are shipped inside Mesa.

To put it simply, they are the endpoints you can read from like a normal IO object. Roger has given a lot of time to the MQTT community, so if you use mosquitto please let him know — and why not donate, as a thank you for all his hard work.

Imagine a set of windows like this. Thu, 28 Sep The more experience you have with Fire, the more you will dislike this new form of energy. Wayland can use almost the entire stack as detailed above to get a framebuffer on your monitor up and running.

Ruby lets you access network services at two levels: It uses card-specific drivers to translate the API into a hardware-specific form.

Once you have a socket open, you can read from it like any IO object.

Sysbench, in-memory, small server: MyRocks over time

Sockets can also communicate within a process, if a communication channel is established there. Note that, depending on the server being tested, a test can take several weeks. This method waits until a client connects to the port you specified, and then returns a TCPSocket object that represents the connection to that client.

Socket Programming and Threads

All socket classes are part of the standard library and not part of the core classesso to use them in your Ruby program, you must first write: Then there are developers who have done this before, using a messaging system.

From there, under the Service Hooks tab, select the MqttPub hook in the list to bring up the configuration options. Otherwise, give the client a successfull connection message. A socket represents a single connection between two network applications.

As X11 is a networked protocol, this means that OpenGL should have to work over the network. The Bad tend to come to the zeromq-dev mailing list with long and unanswerable questions of the form, "How do I use ZeroMQ to do such-and-such.

This method yields the block sequentially. For example, a website might allow deletion of a resource through a URL such as http: Binary downloads will follow in future.

A port may be a Fixnum port number, a string containing a port number, or the name of a service.

Hypertext Transfer Protocol

If you tried out the thing with setting the scale of the windows in GNOME Shell above, you may have been confused at first, and then figured out that your mouse corresponded to the untransformed window.

Scott Hanselman on Programming, The Web, Open Source.NET, The Cloud and More. TCP/IP - Socket Programming [email protected] Jim Binkley 2 sockets - overview read(2) / write(2) with normal TCP, read may return less data than you expect.

Call it. Using TCP Through Sockets David Mazi`eres Revised by Frank Dabek and Eric Petererson you can’t immediately read and write data to a socket returned by socket. You must first assign the socket a local IP address and Note that one can call connect on a TCP socket without first calling bind.

In that.

C - TCP/IP - Writing and reading on a socket

Sockets programming in Ruby Although you can use Ruby to write large programs, part of Ruby's strength as an interpreted scripting language is the ability it gives you to quickly try things out.

Let's TCPServer Helper class for building TCP socket servers. It’s with immense pleasure that I announce the release of the second generation of bettercap, a complete reimplementation of the most complete and advanced Man-in-the-Middle attack framework. This release not only brings MITM attacks to the next level, but it aims to be the reference framework for.

Put just after sock = TCPSocket? – SeanNieuwoudt. if the code of rescue gets executed 10 times, sock will be nil after the for-loop ends.

All Hail Bettercap 0, One Tool to Rule Them All.

You need to make sure sock is a Socket object before calling any method or accessing any attribute of the object itself. SeanNieuwoudt is right. – yeyo.
