Chinese Regulators May Kill Retractable Car Door Handles That Never Should Have Existed

November 26, 2025 by Lewin Day 157 Comments

Headlights. Indicators. Trunk releases. Seatbelts. Airbags. Just about any part of a car you can think of is governed by a long and complicated government regulation. It’s all about safety, ensuring that the car-buying public can trust that their vehicles won’t unduly injure or maim them in regular operation, or in the event of accident.

However, one part of the modern automobile has largely escaped regulation—namely, the humble door handle. Automakers have been free to innovate with new and wacky designs, with Tesla in particular making waves with its electronic door handles. However, after a series of deadly incidents where doors wouldn’t open, regulators are now examining if these door handles are suitable for road-going automobiles. As always, regulations are written in blood, but it raises the question—was not the danger of these complicated electronic door handles easy to foresee?

So Long Firefox, Hello Vivaldi

November 25, 2025 by Jenny List 114 Comments

It’s been twenty-three years since the day Phoenix was released, the web browser that eventually became Firefox. I downloaded it on the first day and installed it on my trusty HP Omnibook 800 laptop, and until this year I’ve used it ever since. Yet after all this time, I’m ready to abandon it for another browser. In the previous article in this series I went into my concerns over the direction being taken by Mozilla with respect to their inclusion of AI features and my worries about privacy in Firefox, and I explained why a plurality of browser engines is important for the Web. Now it’s time to follow me on my search for a replacement, and you may be surprised by one aspect of my eventual choice.

Where Do I Go From Here?

Hackaday in the Ladybird browser — It’s Hackaday, in Ladybird! (Ooof, that font.)

Happily for my own purposes, there are a range of Firefox alternatives which fulfill my browser needs without AI cruft and while allowing me to be a little more at peace with my data security and privacy. There’s Chromium of course even if it’s still way too close to Google for my liking, and there are a host of open-source WebKit and Blink based browsers too numerous to name here.

In the Gecko world that should be an easier jump for a Firefox escapee there are also several choices, for example LibreWolf, and Waterfox. In terms of other browser engines there’s the extremely promising but still early in development Ladybird, and the more mature Servo, which though it is available as a no-frills browser, bills itself as an embedded browser engine. I have not considered some other projects that are either lightweight browser engines, or ones not under significant active development. Continue reading “So Long Firefox, Hello Vivaldi” →

Keebin’ With Kristina: The One With The Elegant Macro Pad

November 24, 2025 by Kristina Panos 9 Comments

Some people are not merely satisfied with functionality, or even just good looks. These persnickety snoots (I am one of them) seek something elegant, a true marriage of form and function.

Should such a person be in the market for a macro pad (or ‘macropad’ if you prefer), that snoot should look no further than [YANG SHU]’s 8-key programmable stream deck-like device.

The main goal here was the perfect fusion of display and feel. I’m not sure that an FDM-printed, DIY macro pad can look any better than this one does. But looks are only half the story, of course. There’s also feel, and of course, functionality.

Yes those are (hot-swappable) mechanical key switches, and they are powered by an ESP32-S2. Drawn on the 3.5″ LCD are icons and text for each switch, which of course can be easily changed in the config app.

There’s a three-direction tact switch that’s used to switch between layout profiles, and I’m sure that even this is satisfying on the feel front. Does it get better than this? Besides maybe printing it in black. I ask Hackaday.

The Unexpected Joys Of Hacking An Old Kindle

November 24, 2025 by Tom Nardi 23 Comments

In the closing hours of JawnCon 0x2, I was making a final pass of the “Free Stuff for Nerds” table when I noticed a forlorn Kindle that had a piece of paper taped to it. The hand-written note explained that the device was in shambles — not only was its e-ink display visibly broken, but the reader was stuck in some kind of endless boot loop. I might have left it there if it wasn’t for the closing remark: “Have Fun!”

Truth is, the last thing I needed was another Kindle. My family has already managed to build up a collection of the things. But taking a broken one apart and attempting to figure out what was wrong with it did seem like it would be kind of fun, as I’d never really had the opportunity to dig into one before. So I brought it home and promptly forgot about it as Supercon was only a few weeks away and there was plenty to keep me occupied.

The following isn’t really a story about fixing a Kindle, although it might seem like it on the surface. It’s more about the experience of working on the device, and the incredible hacking potential of these unassuming gadgets. Whether you’ve got a clear goal in mind, or just want to get your hands dirty in the world of hardware hacking, you could do far worse than picking a couple of busted Kindles up for cheap on eBay.

If there’s a singular takeaway, it’s that the world’s most popular e-reader just so happens to double as a cheap and impressively capable embedded Linux development environment for anyone who’s willing to crack open the case.

Hackaday Links: November 23, 2025

November 23, 2025 by Dan Maloney 19 Comments

Remember the Key Bridge collapse? With as eventful a year as 2025 has been, we wouldn’t blame anyone for forgetting that in March of 2024, container ship MV Dali plowed into the bridge across Baltimore Harbor, turning it into 18,000 tons of scrap metal in about four seconds, while taking the lives of six very unlucky Maryland transportation workers in the process. Now, more than a year and a half after the disaster, we finally have an idea of what caused the accident. According to the National Transportation Safety Board’s report, a loss of electrical power at just the wrong moment resulted in a cascade of failures, leaving the huge vessel without steerage. However, it was the root cause of the power outage that really got us: a wire with an incorrectly applied label.

This Week In Security: Cloudflare Wasn’t DNS, BADAUDIO, And Not A Vuln

November 21, 2025 by Jonathan Bennett 8 Comments

You may have noticed that large pieces of the Internet were down on Tuesday. It was a problem at Cloudflare, and for once, it wasn’t DNS. This time it was database management, combined with a safety limit that failed unsafe when exceeded.

Cloudflare’s blog post on the matter has the gritty details. It started with an update to how Cloudflare’s ClickHouse distributed database was responding to queries. A query of system columns was previously only returning data from the default database. As a part of related work, that system was changed so that this query now returned all the databases the given user had access to. In retrospect it seems obvious that this could cause problems, but it wasn’t predicted to cause problems. The result was that a database query to look up bot-management features returned the same features multiple times.

That featurelist is used to feed the Cloudflare bot classification system. That system uses some AI smarts, and runs in the core proxy system. There are actually two versions of the core proxy, and they behaved a bit differently when the featurelist exceeded the 200 item limit. When the older version failed, it classified all traffic as a bot. The real trouble was the newer Rust code. That version of the core proxy threw an error in response, leading to 5XX HTTP errors, and the Internet-wide fallout.

So Long, Firefox, Part One

November 20, 2025 by Jenny List 153 Comments

It’s likely that Hackaday readers have among them a greater than average number of people who can name one special thing they did on September 23rd, 2002. On that day a new web browser was released, Phoenix version 0.1, and it was a lightweight browser-only derivative of the hugely bloated Mozilla suite. Renamed a few times to become Firefox, it rose to challenge the once-mighty Microsoft Internet Explorer, only to in turn be overtaken by Google’s Chrome.

Now in 2025 it’s a minority browser with an estimated market share just over 2%, and it’s safe to say that Mozilla’s take on AI and the use of advertising data has put them at odds with many of us who’ve kept the faith since that September day 23 years ago. Over the last few months I’ve been actively chasing alternatives, and it’s with sadness that in November 2025, I can finally say I’m Firefox-free.
