How to Create a Custom Physics Engine

June 20, 2017 in C++, Tutorial by Adrian Marius

There are many reasons you might want to create a custom physics engine: first, learning and honing your skills in mathematics, physics and programming are great reasons to attempt such a project; second, a custom physics engine can tackle any sort of technical effect the creator has the skill to create. In this series, Randy Gaul provides a solid introduction on how to create a custom physics engine entirely from scratch.

C++11 multithreading tutorial

January 23, 2017 in C++, Tutorial by Adrian Marius

The code for this tutorial is on GitHub: https://github.com/sol-prog/threads.

In  previous tutorials I’ve presented some of the newest C++11 additions to the language: regular expressions, raw strings and lambdas.

Perhaps one of the biggest change to the language is the addition of multithreading support. Before C++11, it was possible to target multicore computers using OS facilities (pthreads on Unix like systems) or libraries like OpenMP and MPI.

This tutorial is meant to get you started with C++11 threads and not to be an exhaustive reference of the standard.

Unreal Engine sponsors Global Game Jam2017: Development resources released

January 19, 2017 in Game Engines, News, Tips & Tricks, Tutorial, Unreal Engine by admin

From the Unreal Engine blog:

“Running over 48 hours from January 20 – 22, the Global Game Jam will bring developers across the world together to build games. Last year, the event had grown to over 630 sites in 93 countries with over 30,000 jammers, and this year seems set to build on that!

As proud sponsors of the event again this year, we want all of the UE4 developers taking part to be able to get the most out of the engine. In light of this, we asked Mathew Wadstein (well known for his YouTube training videos) to come up with a tips and tricks series. Mathew has created a massive, 27 video, UE4 game jam series to help those participating in the GGJ be more successful with their UE4 games.

This series has many helpful videos including:

  • Quickly building a menu
  • Cooking and packaging
  • Audio tips
  • Materials and HUDs
  • How to use all of our templates
  • Much, much more!”

The entire playlist can be reached here. For more information, follow this link.

Bitbanged USB stack on a sub-$1 Cortex M0+ MCU

January 5, 2017 in ARM, Devices, DIY, Hardware, Microcontroller, Tips & Tricks, Tutorial by admin

A nice presentation about how to get USB running on an sub-$1 Cortex M0+ ARM microcontroller that has no built in USB hardware. The talk describes the implementation of a new bitbanged USB stack, starting with a primer on the USB PHY layer and continuing up the stack, concluding with “Palawan”, a feature-complete open-source bitbanged USB Low Speed stack available for use on microcontrollers priced for under a dollar. We’ll go over requirements for getting USB to work, as well as talking about USB timing, packet order, and how to integrate everything together.

Configuring Primefaces application with glassfish and nginx

July 21, 2016 in Programming, Source Code, Tips & Tricks, Tutorial by admin

primefaces-logoOne of the issues I had these days was installing an Primefaces application in Glassfish application server  running in a container with no external IP address and configuring a nginx front-end for it. While making the two servers work together is just a matter of right configuration files, issues start to pile up when we want to have the context path removed from the nginx. Tried couple of approaches, using URL rewrite, proxy pass, etc, but in the end all of them ended up with links and resource files (ex. CSS files for the themes) not being found. Eventually after many tries ended up with this solution, which (so far) seems to work without any issue. Read the rest of this entry →
