A Portal Port Programmed For Platforms Of The Past

If you still have a Commodore 64 and it’s gathering dust, don’t sell it to a collector on eBay just yet. There’s still some homebrew game development happening from a small group of programmers dedicated to this classic system. The latest is a Portal-like game from [Jamie Fuller] which looks like a blast.

The Commodore doesn’t have quite the same specs of a Playstation, but that’s no reason to skip playing this version. It has the same style of puzzles where the player will need to shoot portals and manipulate objects in order to get to the goals. GLaDOS even …read more

A Whole Other Kind Of Graphical Programming

Java isn’t everyone’s cup of tea. With all its boilerplate and overhead, you’re almost always better off with a proper IDE that handles everything under the hood for you. However, if you learn a new language, you don’t really want to be bothered setting up a clunky and complex IDE. If only you could use a simple, standard Windows program that you are most likely already familiar with. This wish led [RubbaBoy] to create the MSPaintIDE, a Java development environment that let’s you write your code in — yes — MS Paint.

If you’re thinking now that you will end …read more

Become The Rockstar Developer You’ve Always Dreamed Of Being

If you have ever worked in software-related industries, the chances are that the word “Rockstar” will elicit a visceral reaction. It’s a word used by a Certain Type Of Manager for an elite software developer who’s so 1337 they don’t play by the rules of ordinary mortals. In reality it’s use is invariably an indication of trouble ahead, either from clueless startups or troublesome rockstar developers making a toxic atmosphere for the mere members of the backing band. Hackaday has a team that brings together a huge breadth of experience, and we’ve been there.

Would you like to be a …read more

Friday Hack Chat: Making Programming Easier

There is a long history of graphical programming languages. Some people don’t like to code, and for them, graphical programming languages replace semicolons and brackets with easy-to-understand boxes and wires.

This Friday, we’re going to be talking about graphical programming languages with [Boian Mitov]. He’s a software developer, founder of Mitov Software, and the creator of Visuino, a graphical programming language for the embedded domain. He specialized in video, audio, DSP, DAQ, industrial automation, communications, computer vision, artificial intelligence, as well as parallel and distributed computing. [Boian] is the author of the OpenWire open source technology, the IGDI+ open source …read more

State Your Intentions More Clearly With State Machines

To the uninitiated the words ‘State machine’ sound like something scarily big and complex. They aren’t (necessarily) and can be quite useful. In fact, state machines are no physical machines but a model of processes. They link the states a system can be in with allowed transitions. For example a media player when stopped can change to play or open another file. While playing, it can go to pause, stop, reverse, fast forward and so on. A state machine creates a map of all states and how they are connected. It is an abstract tool hat offers a graphical approach …read more

Running Programs On Paper

It’s a simple fact that most programs created for the personal computer involve the same methods of interaction, almost regardless of purpose. Word processors, graphics utilities, even games – the vast majority of interaction is performed through a keyboard and mouse. However, sometimes it can be fun to experiment with alternative technologies for users to interact with code – Paper Programs is an exciting way to do just that.

Paper Programs is a combination of a variety of existing technologies to create a way of interacting with code which is highly tangible. The setup consists of a projector, and a …read more

Solving Mazes with Graphics Cards

What if we told you that you are likely to have more computers than you think? And we are not talking about things that are computers while not looking like one, like most modern cars or certain lightbulbs. We are talking about the powerful machines hiding in your desktop computer called ‘graphics card’. In the ordinary gaming rig graphics cards that are much more powerful than the machine they’re built into are a common occurrence. In his tutorial [Viktor Chlumský] demonstrates how to harness your GPU’s power to solve a maze.

Software that runs on a GPU is called a …read more

Educational Robot for Under $100

While schools have been using robots to educate students in the art of science and engineering for decades now, not every school or teacher can afford to put one of these robots in the hands of their students. For that reason, it’s important to not only improve the robots themselves, but to help drive the costs down to make them more accessible. The CodiBot does this well, and comes in with a price tag well under $100.

The robot itself comes pre-assembled, and while it might seem like students would miss out on actually building the robot, the goal of …read more

Using Modern C++ Techniques with Arduino

C++ has been quickly modernizing itself over the last few years. Starting with the introduction of C++11, the language has made a huge step forward and things have changed under the hood. To the average Arduino user, some of this is irrelevant, maybe most of it, but the language still gives us some nice features that we can take advantage of as we program our microcontrollers.

Modern C++ allows us to write cleaner, more concise code, and make the code we write more reusable. The following are some techniques using new features of C++ that don’t add memory overhead, reduce …read more
