Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation who founded the field of harmonic analysis in the early 1800s. Fourier’s basic insight was that you can represent everything as a sum of […]
Here at Hackaday Central, we fancy that we know a little something about Linux. But if you’d tasked us to run any GUI program inside a Linux terminal, we’d have said that wasn’t possible. But, it turns out, you should have asked [mmulet] who put together term.everything. You might be thinking that of course, you […]
When making a personal website, one will naturally include a personal touch. What could be more personal than creating a font from your own handwriting? That’s what [Chris Smith] has done, and it looks great on his blog, which also has a post summarizing the process. Like most of us [Chris] tried to use open-source […]
If you’re working with a microcontroller that reads a sensor, the chances are that at some point you’re faced with a serial port passing out continuous readings. The workflow of visualizing this data can be tedious, involving a cut-and-paste from a terminal to a CSV file. What if there were a handy all-in-one serial data […]
Retrocomputers need ROMs, but they’re just so read only. Enter the latest incarnation of [Piers]’s One ROM to rule them all, now built with a RP2350, because the newest version is 5V capable. This can replace the failing ROMs in your old Commodore gear with this sweet design on a two-layer PCB, using a cheap […]
You’ve generated a ton of data. How do you analyze it and present it? Sure, you can use a spreadsheet. Or break out some programming tools. Or try LabPlot. Sure, it is sort of like a spreadsheet. But it does more. It has object management features, worksheets like a Juypter notebook, and a software development […]
Over on his blog our hacker [cpt_tom] shows us how to simulate the hardware for a Commodore PET. Two of them in fact, one with static RAM and the other with dynamic RAM. This project is serious business. The simulation environment used is Digital. Digital is a digital logic designer and circuit simulator designed for […]
We can understand why shaderacademy.com chose that name over “the shady school,” but whatever they call it, if you are looking to brush up on graphics programming with GPUs, it might be just what you are looking for. The website offers challenges that task you to draw various 2D and 3D graphics using code in […]
As long as there have been games, there have been crackers breaking their copy protections. “Digital Rights Management” or DRM, is a phrase for copy protection coined near the end of the 1990s, and subverted shortly thereafter. But how? [Nathan Baggs] show us what it took to be a cracker in the year 2000, as […]
There’s long been a push to stop writing code as a sequence of lines and go to something graphical, which has been very successful in some areas and less so in others. But even when you use something graphical like Scratch, it is really standing in for lines of code? Many graphical environments are really […]
