Header files contain function and variable definitions that are imported into C++ programs using the #include statement. Header files have a ".h" extension and declare functions and define macros. When a function is used in a C++ program, its definition must be imported from the library by including the appropriate header file. Common header files provide input/output operations (iostream.h), console input/output (conio.h), formatted I/O (iomanip.h), strings (string.h), mathematics functions (math.h), general purpose functions like memory management (stdlib.h), and random number generation (stdlib.h).
python-message is a Python publish-subscribe broker for messages within an application. It allows components to subscribe to messages on topics and publish messages to subscribed listeners on those topics. Key features include using hashable objects like strings as topics, synchronous publishing to subscribed listeners, and APIs for subscribing, unsubscribing, publishing, and managing topic declarations. Examples show how it can decouple logging from libraries and allow dancing with processes, threads, and coroutines by decorating listener functions.
This document discusses C++ functions. It defines a function as a group of statements that is given a name and can be called from within a program. The structure of a C++ function includes a header and body. The header specifies the return type, name, and parameters, while the body contains the code. Functions can use value, reference, and constant reference parameters. Variables within a function can be local or global. Standard library functions are pre-defined in headers like <iostream> and <math.h>. The document provides examples of defining, calling, and using different types of functions and parameters in C++.
Header files contain function declarations and macro definitions that can be included in C programs using the #include preprocessor directive. They allow code and declarations to be reused across multiple source files. There are two ways to include header files - using angle brackets to search system directories and quotes to search the local directory. The #include directive works by having the preprocessor scan the header file before compiling the rest of the source code. Header files can be included once or multiple times conditionally to avoid errors.
This document discusses C++ functions. It defines standard functions that come with C++ and user-defined functions. It explains the structure of a C++ function including the function header and body. It discusses declaring function signatures separately from implementations. Parameters and scopes are also covered. Examples are provided of standard math and character functions as well as user-defined functions. Header files for organizing function declarations and implementation files are demonstrated.

DEF CON 27 - KYLE GWINNUP - next generation process emulation with bineeFelipe Prado
The document discusses Binee, an emulator that extends existing PE emulators by mocking Windows functions, system calls, and OS subsystems to enable deeper malware analysis. It loads PE files and DLLs, resolves imports, and maps them into emulated memory. Binee defines hooks for functions to intercept calls and interact with mocked subsystems for file I/O, registry, memory, and other OS services. Configuration files define the emulated OS environment to provide context and rapidly change configurations for analysis. This approach aims to reduce the cost of dynamic analysis while extracting more features through emulation at scale.

This document provides an overview of building web applications with R Shiny, an open source package that allows developers to create interactive web apps using R. It discusses the key components of a Shiny app, including the user interface (UI) and server functions. The UI generates the webpage using R functions, while the server executes R code in response to user interactions. Apps can display interactive R analyses and share results without requiring users to have R installed. Basic apps contain a single app.R file with UI and server functions, but more complex apps can split components across multiple files. Input and output elements allow users to interact with widgets and view outputs. The reactive nature of Shiny causes outputs to update automatically in response to input changes.
.NET Fest 2018. Антон Молдован. One year of using F# in production at SBTechNETFest
В 2017 году мы начали активно использовать F# для построения high-load push-based queryable API, а также обработки больших потоков данных (stateful stream processing). На тот момент времени никто в наших командах не имел предыдущего опыта по внедрению и применению F# но мы решили попробовать. На этом докладе я расскажу о нашем опыте внедрения F#, его проблемах и недостатках, о том как мы его научились готовить, где имеет смысл его применять и как подружить C#/OOP с F#/FP в одном проекте.
Данный доклад нацелен на аудиторию не имеющую предыдущего опыта с FP/F#.
Agenda:
- Why did we choose F# over C#?
- A high-level overview of the architecture of our push-based queryable API.
- Adopting F# for C#/OOP developers (inconveniences, C# interoperability, code style, DDD, TDD)

It allows users to write streaming jobs using simple batch-like SQL queries that Spark will automatically optimize for efficient streaming execution. This includes handling out-of-order and late data, checkpointing to ensure fault-tolerance, and providing end-to-end exactly-once guarantees. The talk discusses how Structured Streaming represents streaming data as unbounded tables and executes queries incrementally to produce streaming query results.
1. Update Center Developer’s Guide
Overview
This document is intended to provide information about the various web requests
that can be performed on the Snap Creator Update Center. Each entry details the
format, parameters, and return values. Return values can be formatted in JSON,
XML, or HTML.
Sample codefrom Plugin Controller:
def show
@plugin = Plugin.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render xml: @plugin }
format.json { render json: @plugin }
end
end
Depending on which format the get request is sent, the Update Center will respond
with the same format. Plugins, Agents, and Servers are able to be created, updated,
shown, and deleted through web APIs using json or xml.

})
Demo Server
As an example, we create a demo server that can be run by using rails server just like the
normal Update Center. It should be run on a separate port and assumes that update center is
running on localhost:3000
Update Center Web API Documentation

10. Database Schema
Overview
The Update Center is a tool to help ensure compatibilities between various components
of the Snap Creator Framework, such as agents, plugins, and servers. This requires a
database to keep track of what versions of each component exist and what their
compatibilities are.
Users
This table keeps track of the users in the system. It uses names and emails to help
identify users and has encrypted password and remember tokens to support password-
secure sessions.
ID int
Name string
Email string
Password string (encrypted)
Remember token string (encrypted)
Timestamp datetime
Plugins/Agents/Servers
Plugins/Agents/Servers need to be conscious of their name and enough information to
know which version they are. They also need to know what operating system they are to
disambiguate between the same version for different OSes.
ID int
Name string
Major int
Minor int
11. Revision int
Build int
OS int
Timestamp datetime
Operating System index table
In order to support multiple operating systems dynamically, we decided to make a table
of all operating systems and use the ID associated with it to reference each operating
system in plugins, agents, and servers tables.
ID int
Name string
Architectural int
Agent-Server Compatibility
The compatibility matrices will simply show which agents are compatibility with which
servers, given as IDs into their respective tables. These tables are implemented as a
white list to show what is compatible with what. Similar tables are constructed for
Plugin-Agent and Plugin-Server.
Agent-ServerCompatibility
Agent ID int
Server ID int
12. Plugin-Agent Compatibility
Plugin ID int
Agent ID int
Plugin-Server Compatibility
Plugin ID int
Server ID int
Seeding Database Tables
Overview
Ruby on rails allows an admin to create static table entries that persist through
database resets. We thought it was important to have a set of foundational data
preloaded into the database tables.
Locating the Seed File
The seed file can be found in the project directory under dbseeds.rb
Editing the Seed File
Open the seed file in any text editor.
The first thing you may note is that line comments are generated by a '#'. Anything
follow the pound sign will be commented.
13. In order to make a new entry in a table, simply type the table name, followed by create,
and then enter a value for each column of the table.
Each column must be given a value.
Auto generated values like ID or Timestamp do not need to be given a value here.
Example
Here is an example of adding a row to the Plugins table that contains the columns:
name, major, minor, revision, build, and os
Plugin.create(name: "Cool Plugin", major: "1", minor:"2", revision: "3", build:"4", OS:"1")
