Network Programming with Python

Guide to Network Programming with Python



Python provides two levels of access to network services. At a low level, you can access the basic socket support in the underlying operating system, which allows you to implement clients and servers for both connection-oriented and connectionless protocols.
Python also has libraries that provide higher-level access to specific application-level network protocols, such as FTP, HTTP, and so on.
This chapter gives you understanding on most famous concept in Networking - Socket Programming.

Ebooks: R Programming Language

R is a programming language and software environment for statistical analysis, graphics representation and reporting. R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, and is currently developed by the R Development Core Team. R is freely available under the GNU General Public License, and pre-compiled binary versions are provided for various operating systems like Linux, Windows and Mac. This programming language was named R, based on the first letter of first name of the two R authors (Robert Gentleman and Ross Ihaka), and partly a play on the name of the Bell Labs Language S.

Rust Programming Tutorial

Guide To Rust Programming

Welcome to “Guide To Rust Programming”, an introductory app about Rust. Rust is a programming language that’s focused on safety, speed, and concurrency. Its design lets you create programs that have the performance and control of a low-level language, but with the powerful abstractions of a high-level language.


Rust performs the majority of its safety checks and memory management decisions at compile time, so that your program’s runtime performance isn’t impacted. This makes it useful in a number of use cases that other languages aren’t good at: programs with predictable space and time requirements, embedding in other languages, and writing low-level code, like device drivers and operating systems. It’s also great for web applications: it powers the Rust package registry site, crates.io! We’re excited to see what you create with Rust.

This app is written for a reader who already knows how to program in at least one programming language. After reading this app, you should be comfortable writing Rust programs. We’ll be learning Rust through small, focused examples that build on each other to demonstrate how to use various features of Rust as well as how they work behind the scenes.

Ebooks: Arduino

Arduino Tutorial

Arduino is a prototype platform (open-source) based on an easy-to-use hardware and software. It consists of a circuit board, which can be programed (referred to as a microcontroller) and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and upload the computer code to the physical board.

Arduino boards are able to read analog or digital input signals from different sensors and turn it into an output such as activating a motor, turning LED on/off, connect to the cloud and many other actions.

You can control your board functions by sending a set of instructions to the microcontroller on the board via Arduino IDE (referred to as uploading software).
Unlike most previous programmable circuit boards, Arduino does not need an extra piece of hardware (called a programmer) in order to load a new code onto the board. You can simply use a USB cable.

Additionally, the Arduino IDE uses a simplified version of C++, making it easier to learn to program.

LISP Programming Language ebook

LISP Programming Language tutorials

Lisp is the second-oldest high-level programming language after Fortran and has changed a great deal since its early days, and a number of dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme.

Lisp was invented by John McCarthy in 1958 while he was at the Massachusetts Institute of Technology (MIT).

This reference will take you through simple and practical approach while learning LISP Programming language.

The Lisp Programming Language has an incredible history and is still one of the most widely used programming languages for Artificial Intelligence. Find out what features make it so valuable for AI research and programming.

1. Fanuc G72.1 G72.2 Figure Copy Program Example (Bolt Hole Circle)

This CNC program example shows how both G72.1 and G72.2 figure copy functions can call one-another in one part program, read Programming Notes below carefully.

Programming

Fanuc G72.1 Rotational Copy

Using G72.1 Rotational Copy G-code a figure specified by a subprogram can be repeatedly produced with Rotational movement.
Read G72.1 definition with program example Fanuc G72.1 Rotational Copy (Figure Copy Function CNC Mill)

Fanuc G72.2 Linear Copy

Using G72.2 Linear Copy G-code a figure specified by a subprogram can be repeatedly produced with Linear movement.

Programming Notes

Specifying two or more commands to copy a figure
  1. G72.1 cannot be specified more than once in a subprogram for making a rotational copy (If this is attempted, alarm PS0900 will occur).
  2. G72.2 cannot be specified more than once in a subprogram for making a linear copy (If this is attempted, alarm PS0901 will occur).
  3. In a subprogram that specifies rotational copy, however, linear copy can be specified. Similarly, in a subprogram that specifies linear copy, rotational copy can be specified.

2. Fanuc G72.2 Linear Copy (Figure Copy Function CNC Mill)

Fanuc G72.2 Linear Copy
Using G72.2 Linear Copy G-code a figure specified by a subprogram can be repeatedly produced with Linear movement.

Programming

G72.2 P... L... I... J...

Parameters

ParameterDescription
P       Subprogram number
L       Number of times the operation is repeated
I       Shift along X-axis
J       Shift along Y-axis


G-Code Data
Modal/Non-ModalG-Code Group
     Non-Modal00

Programming Notes

Notes

  1. In the G72.2 block, addresses other than P, L, I and J are ignored.
  2. P, I and J must always be specified.
  3. If L is not specified, the figure is copied once.
  4. For shifts (I, J), specify increments. The n-th geometric shift is equal to the specified shift times (n – 1).

First block of the subprogram

Always specify a move command in the first block of a subprogram that performs a linear copy. If the first block contains only the program number such as O00001234; and does not have a move command, movement may stop at the start point of the figure made by the n-th (n = 1,2, 3, …) copying.

Example of an incorrect program
            O00001234 ;
            G00 G90 X100.0 Y200.0 ;
                ;
                ;
            M99 ;


Example of a correct program
            O00001000 G00 G90 X100.0 Y200.0 ;
                ;
                ;
            M99 ;

Limitation

Specifying two or more commands to copy a figure
G72.2 cannot be specified more than once in a subprogram for making a linear copy (If this is attempted, alarm PS0901will occur).
In a subprogram that specifies linear copy, however, rotational copy (G72.1) can be specified. Similarly, in a subprogram that specifies rotational copy, linear copy can be specified.




Commands that must not be specified
Within a program that performs a linear copy, the following must not be specified:
Command for changing the selected plane (G17 to G19)
Command for specifying polar coordinates (G16)
Reference position return command(G28)
Axis switching
Coordinate system rotation (G68)
scaling (G51)
programmable mirror image (G51.1)

Single block
Single-block stops are not performed in a block with G721.1 or G72.2.
