Write Once, Run Everywhere: Cross-Platform Programming Done Right

One of the goals of programming languages back in the 1950s was to create a way to write assembly language concepts in an abstract, high-level manner. This would allow the same code to be used across the wildly different system architectures of that era and subsequent decades, requiring only a translator unit (compiler) that would transform the source code into the machine instructions for the target architecture.

Other languages, like BASIC, would use a runtime that provided an even more abstract view of the underlying hardware, yet at the cost of a lot of performance. Although the era of 8-bit home computers is long behind us, the topic of cross-platform development is still highly relevant today, whether one talks about desktop, embedded or server development. Or all of them at the same time.

Let’s take a look at the cross-platform landscape today, shall we?

Hackaday Links: April 12, 2015

Everyone loves Top Gear, or as it’s more commonly known, The Short, The Slow, And The Ugly. Yeah, terrible shame [Clarkson] the BBC ruined it for the rest of us. Good News! A show featuring the Dacia Sandero drones will be filling the Top Gear timeslot. And on that bombshell…

More Arduino Drama! A few weeks ago, Arduino SRL (the new one) forked the Arduino IDE from Arduino LLC’s repo. The changes? The version number went up from 1.6.3 to 1.7. It’s been forked again, this time by [Mastro Gippo]. The changes? The version number went up to 2.0. We’re going to hold off until 2.1; major releases always have some bugs that take a few weeks to patch. Luckily the speed of the development cycle here means that patch should be out soon.

Need an ESP8266 connected to an Arduino. Arachnio has your back. Basically, it’s an Arduino Micro with an ESP8266 WiFi module. It also includes a Real Time Clock, a crypto module, and a solar battery charger. It’s available on Kickstarter, and we could think of a few sensor base station builds this would be useful for.

[Ben Heck] gave The Hacakday Prize a shoutout in this week’s episode. He says one of his life goals is to go to space. We’re giving that away to the project that makes the biggest difference for the world. We’re not sure how a [Bill Paxton] pinball machine fits into that category, but we also have a Best Product category for an opportunity to spend some time in a hackerspace… kind of like [Ben]’s 9 to 5 gig…

[Jim Tremblay] wrote a real time operating system for a bunch of different microcontrollers. There are a lot of examples for everything from an Arduino Mega to STM32 Discovery boards. Thanks [Alain] for the tip.

45s – the grammophone records that play at 45 RPM – are seven inches in diameter. Here’s one that’s 1.5 inches in diameter. Does it work? No one knows, because the creator can’t find a turntable to play it on.

Are we betting on the number of people who don’t get the joke in the second paragraph of this post? Decide in the comments.
