Переделка ККМ Атол в термопринтер

Некоторое время назад я увлекался тем, то писал самодельные прошивки для различных готовых устройств. Так, например, сделал пульт для управления солярием из пульта от охранной сигнализации. А что,...

Some reasons to avoid Cython

Cython is an easy way to speed up your Python code—but it doesn’t scale well to large projects.

Приключения капитана Блада: потонет ли Арабелла?

Недавно в сети появилась новость о том, что был открыт исходный код игры "Приключения капитана Блада". Мы не смогли пройти мимо и проверили его качество с помощью PVS-Studio. Потонет ли легендарный...

10 most asked C++ interview questions and answers

C++ is a general-purpose object-oriented programming (OOP) language, developed by Bjarne Stroustrup, and is an extension of the C language. It is therefore possible to code C++ in a "C style" or "object-oriented style." In certain scenarios, it can be coded in either way and is thus an effective example of a hybrid language. #c++ #interview #questions #and #answers

[normalized Sound] A deep dive into dispatching techniques - Jonathan Müller - Meeting C++ 2022

A deep dive into dispatching techniques - Jonathan Müller - Meeting C++ 2022 Slides: https://slides.meetingcpp.com Survey: https://survey.meetingcpp.com At the core of an interpreter is a loop that iterates over instructions and executes them in order. This requires dispatching: based on the current instruction, it needs to select different code. A fast interpreter requires a fast instruction dispatcher, but so does everything else that needs to switch over a fixed set of different options. This talk investigates at various dispatching techniques, from virtual functions over simple switch statements to jump tables. We'll look at performance analysis tools, benchmarks, and lots and lots of assembly code, in order to learn ways to trick the compiler into generating the assembly code that we actually want. Even if you don't need to actually write an interpreter or other dispatcher, you will learn a lot about optimization.

CppNorth and the Forgotten Developers

Mike Daum joins Phil and Timur. After some community news, including the state of modules support in CMake and a new compile-time parsing library inspired by Rust's macros, we talk to Mike about CppNorth - what it is, how it got started and what makes it different - then about company cultures, a new language from Epic, and the importance of catering to 'Dark Matter Developers'.

Improving Output Iterators

Let’s say we had a range, represented by a pair of pointers, that we wanted to copy into another pointer. We might write that like so:

About Safety, Security and yes, C++ and Rust

Recent publications by Consumer Reports and the NSA have launched countless conversations in development circles about safety and its benefits. In these conversations, I’ve seen many misunderstandings about what safety means in programming and how programming languages can implement, help or hinder safety. Let’s clarify a few things.

The Mysterious Life of an Exception Recon 2022

Exceptions are an important control flow mechanism used in many modern programming languages. They allow for control flow to be diverted directly to an exception handler, and are generally used for handling error conditions. It is hard to reverse engineer binaries containing exception handling since the control flow transitions are not obvious and hidden behind layers of indirection. While some off-the-shelf reverse engineering frameworks support automated recovery of exception information, this process is generally not well-understood and documentation about this process is spread out over multiple standards and varies between implementations. In this talk, we will approach reverse engineering exceptions from scratch. After a primer on the Intel Itanium C++ ABI, which specifies how language runtimes implement exceptions on different architectures, we will focus on the exception handling data emitted by the compiler. We will show how to parse and understand the call frame information used for unwinding the…

Unix and C History

Brian Kernighan joins Rob and Jason. They first talk about the pros and cons of virtual teaching and training during COVID times, and the news that BOLT has been merged into LLVM. Then they talk to Brian about the history of UNIX and C development at Bell Labs.
