Hackaday Links: June 7, 2026

Christopher Nolan’s The Odyssey isn’t hitting theaters for another month or so, but if you’re already planning your trip to the cineplex, you may want to check out this page on the movie’s website which lets you view the trailer in the six (!) different formats it’s being released in.

We don’t really have an opinion on the big-screen adaptation of the epic tale as a piece of media, but from a technical standpoint, it’s interesting to see how the viewing experience changes between the 70mm IMAX version with an aspect ratio of 1.43:1 and the 35mm cut at 2.39:1. Unfortunately, the website offers no way to approximate what the movie will look like once compressed, streamed over the Internet, and displayed on a cheap TCL TV, to say nothing of how the viewing experience will be impacted should you watch the movie on your phone by way of a series of short YouTube clips while going to the bathroom. Maybe Nolan is saving that for his next film.

If you head over to the movies in one of Waymo’s vehicles, you can feel a little better about the long-term ecological impact of your trip thanks to a recently announced partnership between the autonomous car maker and B2U Storage Solutions. Under the agreement, old batteries pulled from Waymo’s fleet of self-driving electric cars will get a second life as localized grid storage.

The idea is that batteries which no longer hold enough charge to power a robo-taxi should still have enough capacity to store the energy produced by renewable sources so it can be doled out later when the demand goes up. By installing these batteries in the cities that Waymo actually operates their vehicles in, they don’t have to worry about shipping them around either — they can just yank them out of the car, and wire them right into the grid. Of course, eventually the batteries will be too cooked to adequately perform in this role as well, but this should give them a few more productive years before they get torn down and scrapped.

Fork! Ladybird Browser And SerenityOS To Go Separate Ways

In the monthly Ladybird Browser update video which we’ve placed below, SerenityOS founder [Andreas Kling] announced an interesting development. The browser has been forked from the OS that has been its progenitor, and both projects will now proceed separately. This frees the browser from the SerenityOS insistence on avoiding external libraries, and allows it to take advantage of stable, fast, and mature open source alternatives. This is already paying dividends in compatibility and speed, and is likely to lead further towards a usable everyday browser as time goes by.

As the world of fully-featured web browser engines has contracted from a number of different projects to little more than Google’s Blink and Mozilla’s Gecko, Ladybird has found itself in an unexpected position. It is vital that the browser market retains some competition and does not become a Google monoculture, so while it might not seem so at first glance, the news of Ladybird going alone has the potential to be one of the most far-reaching open source stories of the year.

If you’d like to try Ladybird you’ll have to get your hands slightly dirty and build it yourself, but we’d expect ready-built versions to appear in due course. We took a look at an earlier version of Ladybird last year, as well as SerenityOS itself.

Jenny’s Daily Drivers: SerenityOS, And In Particular, Ladybird

As we continue on with the series in which I take a different OS for a spin every month I am afraid, dear reader, that this month I have a confession to make. Our subject here isn’t a Daily Driver at all, and it’s not the fault of the operating system in question. Instead I’m taking a look at a subject that’s not quite ready for the big time but is interesting for another reason. The OS is SerenityOS, which describes itself as “a love letter to ’90s user interfaces with a custom Unix-like core“, and the reason I’m interested in it comes from its web browser. I know that the OS is very much a work in progress and I’ll have to forgo my usual real hardware and run it in QEMU, but I’ve heard good things about it and I want to try it. The browser in question is called Ladybird, and it’s interesting because it has the aim of creating a modern fully capable cross-platform browser from scratch, rather than being yet another WebKit-based appliance.

A Pleasant Trip Into The 1990s

Part of a Linux desktop with the SerenityOS build instructions in the background, a terminal having built the OS, and the OS itself in a QEMU window.
My first look at SerenityOS after building it.

SerenityOS isn’t ready to be installed on real hardware, and there’s no handy ISO to download. Instead I had to clone the repository to my Linux machine and run the build script to compile the whole thing, something I was very pleased to observe only took about 40 minutes. It creates a hard disk image and opens QEMU for you, and you’re straight into a desktop.

When they mention ’90s user interfaces they definitely weren’t hiding anything, because what I found myself in could have easily been a Windows 9x desktop from the middle of that decade. There are  a bunch of themes including some Mac-like ones, but should you select the “Redmond” one, you’re on very familiar ground if you had a Microsoft environment back then. It’s only skin-deep though, because as soon as you venture into a command line shell there’s no DOS to be found. This is a UNIX-like operating system, so backslashes are not allowed and it’s familiarly similar to an equivalent on my Linux box. The purpose of this review is not to dive too far into the workings of the OS, but suffice it to say that both the underpinnings and the desktop feel stable and as polished as a Windows 95 lookalike can be. The various bundled utilities and other small programs seem to work well, and without any hint of the instabilities I’ve become used to when I’ve experimented with other esoteric operating systems.
