    multiprocesscallback.py, by Peter Sobot (psobot.com), May 13, 2012
    
    Handles callback functions in classes that have member functions that
    are executed in a different process. A crazy experiment in Python
    magic that breaks a lot of rules.
    
    Do not use in production, for any reason. (Although I do.)
    
    If your class takes in a callback, like so:

pgorczak

import logging

import rospy

# Messages sent to my_logger will not be directed to stdout.
# They will show up in rqt_console with my_logger associated to the node.
logging.getLogger('my_logger').addHandler(rospy.impl.rosout.RosOutHandler())
logging.getLogger('my_logger').setLevel(logging.INFO)

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Building a Nix Package (The C&C++ Version)

Nix can be used to build any kind of package. But here I'm just going to focus on the simple C&C++ case.

Firstly we have to know that the final built packages will located inside /nix/store. Which is globally readable directory of all build inputs and build outputs of the Nix system. The emphasis is on readable, not writable, that is /nix/store is meant to be modified by the user or programs except for the Nix system utilities. This centralises the management of packages, and keeps our packages and package configuration consistent.

So what exactly are we trying to build. Our goal is to build a directory that will be located in /nix/store/*-package-version/, where * is the hash of the package. Preferably a version is also available, but some C&C++ packages don't have versions, so in that case, there's only /nix/store/*-package/.

What will be inside this directory? It follows the GNU Coding Standards descri

Using py.test is great and the support for test fixtures is pretty awesome. However, in order to share your fixtures across your entire module, py.test suggests you define all your fixtures within one single conftest.py file. This is impractical if you have a large quantity of fixtures -- for better organization and readibility, you would much rather define your fixtures across multiple, well-named files. But how do you do that? ...No one on the internet seemed to know.

Turns out, however, you can define fixtures in individual files like this:

tests/fixtures/add.py

import pytest

@pytest.fixture

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
