A History Of Pong

July 28, 2025 by 8 Comments

Today, creating a ground-breaking video game is akin to making a movie. You need a story, graphic artists, music, and more. But until the middle of the 20th century, there were no video games. While several games can claim to be the “first” electronic or video game, one is cemented in our collective memory as the first one we’d heard of: Pong.

The truth is, Pong wasn’t the first video game. We suspect that many people might have had the idea, but Ralph Baer is most associated with inventing a practical video game. As a young engineer in 1951, he tried to convince his company to invest in games that you could play on your TV set. They didn’t like the idea, but Ralph would remember the concept and act on it over a decade later.

But was it really the first time anyone had thought of it? Perhaps not. Thomas Goldsmith Jr. and Estle Ray Mann filed a patent in 1947 for a game that simulated launching missiles at targets with an oscilloscope display. The box took eight tubes and, being an oscilloscope, was a vector graphic device. The targets were physical dots on a screen overlay. These “amusement devices” were very expensive, and they only produced handmade prototypes.

Wayland Will Never Be Ready For Every X11 User

July 28, 2025 by 140 Comments

After more than forty years, everyone knows that it’s time to retire the X Window System – X11 for short – on account of it being old and decrepit. Or at least that’s what the common narrative is, because if you dig into the chatter surrounding the ongoing transition there are some real issues that people have with the 16-year old spring chicken – called Wayland – that’s supposed to replace it.

Recently [Brodie Robertson] did some polling and soliciting commentary from the community, breaking down the results from over 1,150 comments to the YouTube community post alone.

The issues range from the expected, such as applications that haven’t been ported yet from X11 to Wayland, to compatibility issues – such as failing drag and drop – when running X11 and Wayland applications side by side. Things get worse when support for older hardware, like GeForce GT610 and GT710 GPUs, and increased resource usage by Wayland are considered.

From there it continues with the lack of global hotkeys in Wayland, graphics tablet support issues, OBS not supporting embedded browser windows, Japanese and other foreign as well as onscreen keyboard support issues that are somehow worse than on X11, no support for overscanning monitors or multiple mouse cursors, no multi-monitor fullscreen option, regressions with accessibility, inability of applications to set their (previously saved) window position, no real automation alternative for xdotool, lacking BSD support and worse input latency with gaming.

Some users also simply say that they do not care about Wayland either way as it offers no new features they want. Finally [Brodie] raises the issue of the Wayland developers not simply following standards set by the Windows and MacOS desktops, something which among other issues has been a point of hotly debated contention for years.

Even if Wayland does end up succeeding X11, the one point that many people seem to agree on is that just because X11 is pretty terrible right now, this doesn’t automatically make Wayland the better option. Maybe in hindsight Mir was the better choice we had before it pivoted to Wayland.

Commodore 64 On New FPGA

July 28, 2025 by 19 Comments

When it comes to getting retro hardware running again, there are many approaches. On one hand, the easiest path could be to emulate the hardware on something modern, using nothing but software to bring it back to life. On the other, many prefer to restore the original hardware itself and make sure everything is exactly as it was when it was new. A middle way exists, though, thanks to the widespread adoption of FPGAs which allow for programmable hardware emulation and [Jo] has come up with a new implementation of the Commodore 64 by taking this path.

The project is called the VIC64-T9K and is meant as a proof-of-concept that can run the Commodore 64’s VIC-II video chip alongside a 6502 CPU on the inexpensive Tang Nano 9k FPGA. Taking inspiration from the C64_MiSTer project, another FPGA implementation of the C64 based on the DE10-Nano FPGA, it doesn’t implement everything an original Commodore system would have had, but it does provide most of the core hardware needed to run a system. The project supports HDMI video with a custom kernel, and [Jo] has used it to get a few demos running including sprite animations.

Built with a mix of Verilog and VHDL, it was designed as a learning tool for [Jo] to experiment with the retro hardware, and also brings a more affordable FPGA board to the table for Commodore enthusiasts. If you’re in the market for something with more of the original look and feel of the Commodore 64, though, this project uses the original case and keyboard while still using an FPGA recreation for the core of the computer.
