The life of a Hackaday writer often involves hours spent at a computer searching for all the cool hacks you love, but its perks come in not being tied to an office, and in periodically traveling around our community’s spaces. This suits me perfectly, because as well as having an all-consuming interest in technology, I […]
The world’s militaries have always been at the forefront of communications technology. From trumpets and drums to signal flags and semaphores, anything that allows a military commander to relay orders to troops in the field quickly or call for reinforcements was quickly seized upon and optimized. So once radio was invented, it’s little wonder how […]
The word “Schlieren” is German, and translates roughly to “streaks”. What is streaky photography, and why might you want to use it in a project? And where did this funny term come from? Think of the heat shimmer you can see on a hot day. From the ideal gas law, we know that hot air […]
Not too long ago, I was searching for ideas for the next installment of the “Big Chemistry” series when I found an article that discussed the world’s most-produced chemicals. It was an interesting article, right up my alley, and helpfully contained a top-ten list that I could use as a crib sheet for future articles, […]
If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At least not without a liberal amount of adhesive, water or some other substance to facilitate a temporary or more permanent bond. This assumption gets tossed out of the window when it comes to […]
Once upon a time, typing “www” at the start of a URL was as automatic as breathing. And yet, these days, most of us go straight to “hackaday.com” without bothering with those three letters that once defined the internet. Have you ever wondered why those letters were there in the first place, and when exactly […]
As the Common Business Oriented Language, COBOL has a long and storied history. To this day it’s quite literally the financial bedrock for banks, businesses and financial institutions, running largely unnoticed by the world on mainframes and similar high-reliability computer systems. That said, as a domain-specific language targeting boring business things it doesn’t quite get […]
In the 2000s, the DVD industry was concerned about piracy, in particular the threat to their business model presented by counterfeit DVDs and downloadable movies. Their response was a campaign which could be found embedded into the intro sequences of many DVDs of the era, in which an edgy font on a black background began […]
Whenever the topic is raised in popular media about porting a codebase written in an ‘antiquated’ programming language like Fortran or COBOL, very few people tend to object to this notion. After all, what could be better than ditching decades of crusty old code in a language that only your grandparents can remember as being […]
An occasional series of mine on these pages has been Daily Drivers, in which I try out operating systems from the point of view of using them for my everyday Hackaday work. It has mostly featured esoteric or lesser-used systems, some of which have been unexpected gems and others have been not quite ready for […]
