If you write software, chances are you’ve come across Continuous Integration, or CI. You might never have heard of it – but you wonder what all the ticks, badges and mysterious status icons are on open-source repositories you find online. You might hear friends waxing lyrical about the merits of CI, or grumbling about how their pipeline has broken again.
Want to know what all the fuss is about? This article will explain the basic concepts of CI, but will focus on an example, since that’s the best way to understand it. Let’s dive in. Continue reading “Continuous Integration: What It Is And Why You Need It”
When it comes to building sets and props for movies and TV, it’s so easy to get science fiction wrong – particularly with low-budget productions. It must be tempting for the set department to fall back on the “get a bunch of stuff and paint it silver” model, which can make for a tedious experience for the technically savvy in the audience.
But low-budget does not necessarily mean low production values if the right people are involved. Take [Joel Hartlaub]’s recent work building sets for a crowdfunded sci-fi film called Infinitus. It’s a post-apocalyptic story that needed an underground bunker with a Fallout vibe to it, and [Joel] jumped at the chance to hack the sets together. Using mainly vintage electronic gear and foam insulation boards CNC-routed into convincing panels, he built nicely detailed control consoles for the bunker. A voice communicator was built from an old tube-type table radio case with some seven-segment displays, and the chassis of an old LCD projector made a convincing portable computer terminal. The nicest hack was for the control panel of the airlock door. That used an old TDD, or telecommunications device for the deaf. With a keyboard and a VFD display, it fit right into the feel of the set. But [Joel] went the extra mile to make it a practical piece, by recording the modulated tones from the acoustic coupler and playing them back, to make it look as if a message was coming in. The airlock door looks great too.
Like many hacks, it’s pretty impressive what you can accomplish with a deep junk pile and a little imagination. But if you’ve got a bigger budget and you need some computer displays created, we know just the person for the job.

A few months ago, [Ulysses] had a project in mind that would run Zork on a TDD. Although it was a bit of a struggle getting the project ready in time for the Bay Area Maker’s Faire, the accompanying build blog tells us it was more than worth the effort.
After hooking up the guts of the phone to an Arduino Pro, A modem was modified so the acoustically coupled TDD could be interfaced. Although the TDD display is only one line, [Ulysses] is transmitting the text at only 45.5 baud, So even the slowest reader could keep up with the story. For running the actual code, initial attempts at using an Arduino Pro, and then Arduino Mega proved unsuccessful because of the limitations of sram in these AVRs. After discarding the idea of running Zork on an Arduino, the project was finished with a single board FitPC computer mounted inside the phone.
The code of the project runs Zork on a port of the Infocom Z-code Interpreter Program, or ZIP. A lot of interactive text adventures were put out in the Z-code format, so we’re guessing it would be trivial to have this project run Leather Goddesses of Phobos, or the amazing Hitchhiker’s Guide to the Galaxy. It’s a very nice project, and we could easily see ourselves sitting down with this project, a two liter bottle of Shasta, and an all-Rush mix tape on a Saturday night.
