This document discusses using the C to Go translation tool c2go to translate C code implementing quicksort algorithms into Go code. It provides examples of translating simple quicksort C code, improving the translation by using a configuration file, and how c2go handles standard C functions like qsort by translating them to their Go equivalents. The examples demonstrate how c2go can generate valid Go code from C code but may require some manual fixes or configuration to handle certain data structures or language differences.
This document summarizes the key changes and new features introduced in Python 3, including:
- Strings are now unicode by default and implicit conversions between str and bytes are prohibited.
- Integers are unified under int and long is removed.
- New features like formatted string literals, function annotations, nonlocal and keyword-only arguments, extended iterable unpacking, comprehensions, exception chaining, and yield from.
- New collection abstract base classes and data structures like OrderedDict and Counter.
- Metaclasses can now control class creation and new metaclass like OrderedClass is introduced.
- Under the hood improvements including a new GIL and stable ABI version tagged shared object files.
Swift is a compiled, statically typed programming language that was first released in 2014 and became open source in 2015. It supports object-oriented, procedural, and functional programming paradigms. Swift has built-in support for arrays, dictionaries, tuples, and sets, as well as common control flow constructs like conditionals and loops. Users can define classes, structures, and enumerations and protocols to organize their code. Functions, closures, and objects are supported.
Why we are submitting this talk? Because Go is cool and we would like to hear more about this language ;-). In this talk we would like to tell you about our experience with development of microservices with Go. Go enables devs to create readable, fast and concise code, this - beyond any doubt is important. Apart from this we would like to leverage our test driven habbits to create bulletproof software. We will also explore other aspects important for adoption of a new language.
This document discusses Java collections frameworks. It covers core collection interfaces like List, Set, Queue and Map. It also discusses concrete collection classes that implement these interfaces like ArrayList, LinkedList, HashSet, TreeSet, HashMap and TreeMap. The document further explains concepts like iterators, generics in collections and differences between collections before and after generics.
This document discusses input and print functions in Python. It explains that the print function displays information to the user and includes examples of printing different data types. It also explains that the input function accepts information from the user, stores it in a variable, and can include a prompt. Examples are provided of getting both string and numeric input and converting the input to other data types like integers. The document also covers simple formatting options for print like printing on new lines, adding separators, or printing on the same line.
This document contains 3 solutions to C++ programming problems involving basic data types and classes.
Solution 1 defines a phone number struct and demonstrates initializing instances, getting user input, and outputting phone numbers. Solution 2 defines a point struct and shows adding the x and y coordinates of two points to find the sum. Solution 3 defines a Rectangle class with private width and length variables, and public methods to set/get dimensions and calculate perimeter and area, demonstrating default values and bounds checking.
Rust
Why do you care about Rust? Who has the time to learn all these new languages? It seems like a new one is popping up every other week and this trend is growing at an exponential rate. Good news, a fair number of them are crafted really well and efficiently solve specific problems. Bad news, how do you keep up with all of this, let alone decide which languages to include in your companies technology portfolio.
Despite the challenges of all these new languages, a majority of developers are intrigued about the idea of becoming a polyglot, but don't know where to begin or don't have the time. In my polyglot travels, there is one language of late that is the sure-fire answer to the above questions, Rust.
In this talk I’ll explore the value behind becoming more polyglotic as a developer, how to pick languages to learn, and then dive deep in the the language of Rust. Which in my opinion, is hands down the best up and coming languages to learn.

The document discusses closures in programming languages, providing examples of how closures work in JavaScript by allowing inner functions to access variables in an enclosing scope. It explains that while Java 8 introduced lambda expressions, lambda expressions in Java are not true closures since they do not close over variables in enclosing scopes. The document concludes that a closure is a function that closes over the environment in which it was defined, whereas a lambda is just an anonymous function.
A reworking of my 2010 RubyConf lightning talk introducing Go via a concurrent implementation of MapReduce. This code is probably buggy as hell and the design awful but it's also a reasonably good intro to the full breadth of Go.
This document describes an implementation of RSA encryption and decryption algorithms along with additional functions for generating prime numbers, computing the encryption and decryption keys, encrypting and decrypting messages, and timing the processes. The code includes functions for integer to text conversion, modular exponentiation, extended Euclidean algorithm, and transposition cipher encryption of the ciphertext for additional obfuscation. An example use case at the end demonstrates generating primes, encrypting and decrypting a sample message, and timing the processes.

Better Reflection is an awesome new library that uses magical time-warp techniques* (*actual magic or time-warp not guaranteed) to improve on PHP’s built-in reflection by providing additional functionality. In this talk we’ll briefly explore the cool features of Better Reflection, and how you can use Better Reflection in your projects to maximise your reflection-fu.
Помните легендарные Java Puzzlers? Да-да, те самые, с Джошом Блохом и Нилом Гафтером? Ну, по которым ещё книжку написали? Так вот, в Groovy всё ещё веселее.
В смысле — задачки ещё более странные, и ответы ещё более поразительные. Этот доклад для вас, Groovy-разработчики, мы покажем вам настоящие, большие и красивые подводные камни! И для вас, Java-разработчики, потому что таких вещей на Java-подобном синтакисе вы точно никогда не видели! И для вас, PHP-разработчики… хотя, нет, не для вас :)
Всем точно будет весело — ваши ведущие Женя и Барух будут зажигать, шутить, спорить, бросаться футболками в публику, и самое главное — заставят вас офигевать от Groovy.
TypeScript is a superset of JavaScript that compiles to JavaScript. It adds optional static typing, classes, interfaces, and other features to JavaScript to help catch errors. TypeScript files use the .ts extension and can be compiled to JavaScript using the TypeScript compiler. Key features of TypeScript include static typing for variables, interfaces for defining object structures, classes and inheritance for object-oriented programming, and modules for code organization.
This document provides an overview of classes in C++. It begins with definitions and concepts related to classes, such as encapsulation and user-defined types. It then provides examples of declaring and defining a simple Time class with attributes like hours, minutes, seconds and methods to set, get, print and change the time. The document also discusses class members, access specifiers, constructors, pointers and references to class objects, and getter and setter methods. It concludes with brief mentions of utility functions, separating interface from implementation, and organizing classes across header and source files.
This document provides an overview of using the Vim text editor and its many features for coding. It covers Vim basics like modes, windows, buffers and tabs. It then details various commands and plugins for navigation, searching/replacing, diffing, tags management, autocomplete, syntax checking, key remapping, colorschemes, and working with the Linux shell. The document emphasizes that Vim can serve as a full-fledged IDE and recommends plugins to enhance its functionality for directory viewing, highlighting, autocompletion, and more. It provides references for further learning Vim's grammar and shortcuts.
Rust — это современный, практический, быстрый и безопасный язык программирования. Некоторые говорят, что Rust — это как C++, если бы его писал человек, знающий Haskell.
Система типов Rust решает главную проблему C++ — небезопасность. C++ очень легко сделать ошибки, которые приведут к поломкам (например, use after free). Rust позволяет писать безопасный код, сохраняя при этом выразительность и околонулевые накладные расходы C++. В докладе будут подробно описаны механизмы языка, которые контролируют безопасность программы.
Хотя в данный момент Rust ещё не подходит для использования в продакшне, его всё равно стоит изучать. Во-первых, потому что это очень интересный подход к программированию, а во-вторых, потому что через несколько лет для разработки требовательных к ресурсам программ будет необходим именно Rust или другой похожий инструмент.

The Ring programming language version 1.5.3 book - Part 25 of 184Mahmoud Samir Fayed
This document provides summaries of various file handling functions in Ring programming language including Read(), Write(), Dir(), Rename(), Remove(), fopen(), fclose(), fflush(), freopen(), tempfile(), tempname(), fseek(), ftell(), rewind(), fgetpos(), fsetpos(), clearerr(), feof(), ferror(), perror(), fgetc(), fgets(), fputc(), fputs(), ungetc(), fread(), fwrite(), fexists(), and describes how to use numbers and bytes with files. Examples are given to demonstrate the use of these functions for tasks like reading and writing files, getting directory listings, opening and closing files, seeking within files, and checking for errors.
The document provides an introduction to the Clojure programming language. It discusses that Clojure is a functional Lisp dialect that runs on the Java Virtual Machine. It extends the principle of code-as-data to include maps and vectors in addition to lists. The document also provides an overview of Clojure's core data structures, functions, concurrency features like atoms and agents, and how to get started with Clojure.
These are the slides of the second part of this multi-part series, from Learn Python Den Haag meetup group. It covers List comprehensions, Dictionary comprehensions and functions.
Python is a multi-paradigm programming language created in 1989 by Guido van Rossum. It is based on ABC and Modula-3 and was named after Monty Python. Python has a simple syntax and dynamic typing and memory management. It can be used for web development, data science, scientific computing, and more. The core philosophy is summarized in the Zen of Python document. Python code is written, tested, and executed using integrated development environments like PyCharm or directly from the command line.
The document provides code snippets for creating programs in C to:
1. Restrict mouse pointer movement and display pointer position by accessing the interrupt table and using functions like int86().
2. Create simple viruses by writing programs that shutdown the system, open internet explorer infinitely, or delete IE files.
3. Create DOS commands by writing C programs that can be executed from the command line to list files or directories.
4. Switch to 256 color graphics mode and create directories by calling int86() and writing to registers.
5. Develop a basic paint brush program using graphics functions to draw shapes determined by brush properties when the mouse is clicked.
This document provides an overview of dictionaries in Python. It discusses how dictionaries are defined using curly braces {}, how keys can be any immutable object like strings or numbers while values can be any object, and how to access values using keys. It also covers adding and deleting key-value pairs, checking for keys, shallow and deep copying, and creating dictionaries from keys or sequences.
This document provides an introduction and overview of the Go programming language. It discusses key Go concepts like concurrency using goroutines and channels, object-oriented programming using structs and interfaces, and real-world examples of Go in production systems. The document covers Go's simplicity, concurrency features, interfaces, and how these properties make Go well-suited for building scalable and performant web applications. It also provides performance comparisons between Ruby and Go implementations for common tasks.
1. The document discusses user-defined and standard functions in C programming. It provides examples of function prototypes, definitions, and calls.
2. Key points covered include function return types, parameters, local variable declarations, and scope. Header files and standard library functions are also mentioned.
3. Examples show how to define, declare, and call functions of different types (void, non-void) with and without parameters in C code.
Rust provides memory safety without garbage collection through its ownership and borrowing model that is checked at compile time. Ownership rules ensure that references to resources like vectors remain valid by moving the vector when it is passed to a function. Borrowing allows immutable or mutable references to a resource, but not both at the same time, avoiding data races. Rust achieves performance comparable to C++ through its zero-cost abstractions and moves semantics that avoid unnecessary data copying.
Go is an open source programming language designed by Google to be concurrent, garbage collected, and efficient. It has a simple syntax and is used by Google and others to build large distributed systems. Key features include garbage collection, concurrency with goroutines and channels, interfaces without inheritance, and a large standard library.
Spread syntax and rest syntax allow iterable objects like arrays and strings to be expanded in function calls, array literals, and object literals. Spread syntax spreads the elements into separate arguments/elements, while rest syntax collects remaining elements into a single variable. Tagged template literals allow functions to operate on template literal strings before they are evaluated. Decorators propose a way to annotate and modify classes and class elements.
C# 3.0 introduces many features common in functional programming languages like generics, first-class functions, lambda expressions, and type inference. However, C# retains its object-oriented roots, and some features like datatypes and laziness remain more fully realized in pure functional languages. While C# supports programming in a functional style, its performance characteristics and lack of optimizations mean it may not be a serious competitor to ML and Haskell for functional programming tasks.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
2. About Rust
● New systems programming language by Mozilla.
● Designed to write secure code:
● Memory safety
● Thread safety
● Performance similar to C++
4. Cargo
Cargo.toml
[package]
name = "program"
version = "0.1.0"
authors = ["John D <john.d@test.com>"]
[features]
default = [ ]
[dependencies]
num = "0.1.27"
Commands
$ cargo build
$ cargo test
$ cargo run
$ cargo new title [--bin]
Tool used for downloading dependencies, building dependencies and
building our program.
6. Variable bindings
A 'let' expression is a pattern:
let(x, y) = (42, 24); // x = 42, y = 24
Variable bindings are immutable by default:
let x = 42;
x = 10;// error
let mut x = 42;
Type inference:
let x: i32 = 10; // Same as let x = 10;
7. Stack and Heap
fn main() {
let x = Box::new(5);
let y = 42;
let z = &x;
}
Box<T> implements Drop, it is freed when it goes out of
scope
Address Name Value
2^30
...
5
2 z → 0
1 y 42
0 x → 2^30
8. Vector
● Provided by the std library
● Growable (dynamic)
● Can implement any type: Vec<T>
let v = vec![1, 2, 3, 4, 5]; // v: Vec<i32>
let mut my_vector: Vec<u8> = Vec::new();
let v = vec![0; 10];
for i in &v {
println!("Reference to {}", i);
}
for point in fractal.iter() {
if *point == 0 {…}
}
10. Pattern matching
let x = 3;
match x {
1 => println!("one"),
2 | 3 => println!("two or three"),
x @ 4..10 => println!(“say {}”, x),
_ => println!("i can't count that much"),
}
11. Result<T, E>
To manage errors, we can use the type system:
enum Result<T, E> {
Ok(T),
Err(E)
}
// Result<T, String>
fn division(num: f64, den: f64) -> Result<f64, String> {
if den == 0.0 {
Err(“Error”)
} else {
Ok(num / den)
}
}
12. Ownership
Variable bindings imply there is an owner to an asset
fn foo() {
let v = vec![1, 2, 3];
}
1) v in scope: Vec<i32> is created
2) Vector lives in the heap
3) Scope ends: v is freed, heap
allocated vector is cleaned.
There is only one binding to any asset. Lifetimes and transferring
ownership must be considered.
fn read_vector(vec: Vec<i32>) {
println!("{:?}", vec);
}
fn main() {
let my_vector = vec!(1, 3, 5, 7);
read_vector(my_vector);
println!("{:?}", my_vector); // error
}
13. Ownership
Give back ownership:
fn read_vector(vec: Vec<i32>) -> Vec<i32> {
println!("{:?}", vec);
vec
}
Borrowing (pass by reference):
fn read_vector(vec: &Vec<i32>) {
println!("{:?}", vec);
}
fn main() {
let my_vector = vec!(1, 3, 5, 7);
...
}
14. Ownership
Mutable reference: &mut
fn add_to_vector(vec: &mut Vec<i32>) {
vec.push(10);
}
fn main() {
let mut my_vector = vec!(1, 3, 5, 7);
add_to_vector(&mut my_vector);
println!("{:?}", my_vector);
}
● Any borrow's scope may not last longer than the owner
● Can exist many immutable borrows, (&x)
● Only one mutable reference (&mut x)
15. Traits
// TRAIT: Tells about a functionality a type has to provide
trait Dimensional {
fn area(&self) -> i32;
}
// Function for any type that implements the Dimensional trait
fn print_area<T: Dimensional>(object: T) {
println!("Area: {}", object.area());
}
struct Rectangle {x1: i32, y1: i32, x2: i32, y2: i32,}
impl Dimensional for Rectangle {
fn area(&self) -> i32 {
(self.x2 - self.x1) * (self.y2 - self.y1)
}
}
fn main() {
let r = Rectangle { x1: 0, x2: 4, y1: 0, y2: 2, };
print_area(r);
}
16. Closures
● Anonymous functions
● Rust imposes less restrictions about type annotations:
● Argument types and return types can be inferred
● May be multi-line, with statements between { }
fn main() {
let multiply = |x, y| x * y;
let sum_squares = |x: i32, y: i32| -> i32 {
let x = x * x;
let y = y * y;
x + y
};
println!("{:?}", multiply(2, 3));
println!("{:?}", sum_squares(2, 3));
}
17. Threading (spawning)
● A thread can be spawned with thread::spawn
● Accepts a closure and returns a handle
● Handles can be error checked with the Result Enum
use std::thread;
fn main() {
let handle = thread::spawn(|| "Hello".to_string());
match handle.join() {
Ok(x) => println!("{}", x),
Err(e) => println!("{:?}", e),
}
}
18. Other features
● Foreign Function Interface in 2 directions:
● Can call C code into Rust
● Can call Rust into other programs
● Conditional compilation by passing flags and assisted by Cargo
[features]
secure-password = ["bcrypt"]
● Use of 'raw pointers' (marked as unsafe to the compiler)
let x = 5;
let raw = &x as *const i32;
let points_at = unsafe { *raw };
println!("raw points at {}", points_at);
19. Rust projects
● Maidsafe (http://maidsafe.net/)
“ MaidSafe is a fully decentralized platform on which
application developers can build decentralized applications”
● Crates.io (https://crates.io/)
A catalog with Rust crates
● Servo (https://github.com/servo/servo)
“Servo is a prototype web browser engine written in the Rust
language. It is currently developed on 64bit OS X, 64bit Linux,
Android, and Gonk (Firefox OS).”
