Meet The Winners Of The 2024 Tiny Games Contest

September 18, 2024 by Tom Nardi 12 Comments

Over the years, we’ve figured out some pretty sure-fire ways to get hackers and makers motivated for contests. One of the best ways is to put arbitrary limits on different aspects of the project, such as how large it can be or how much power it can consume. Don’t believe us? Then just take a look at the entries of this year’s Tiny Games Contest.

Nearly 80 projects made it across the finish line this time, and our panel of judges have spent the last week or so going over each one to try and narrow it down to a handful of winners. We’ll start things off with the top three projects, each of which will be awarded a $150 gift certificate from our friends at DigiKey.

First: Sub-Surface Simon

While this contest saw a lot of excellent entries, we don’t think anyone is going to be surprised to see this one take the top spot. Earning an exceptionally rare perfect ten score from each of our judges, Sub-Surface Simon from [alnwlsn] grabbed onto the theme of this contest and ran like hell with it.

Keebin’ With Kristina: The One With The (Mc)Cool Typewriter

Okay, so this isn’t a traditional keyboard, but you can probably figure out why the RuneRing is here. Because it’s awesome! Now, let me give you the finer points.

Hugely inspired by both ErgO and Somatic, RuneRing is a machine learning-equipped wearable mouse-keyboard that has a configurable, onboard ML database that can be set up to detect any gesture.

Inside the ring is a BMI160 6-axis IMU that sends gesture data to the Seeed Studio nRF52840 mounted on the wrist. Everything is powered with an 80mAh Li-Po lifted from a broken pair of earbuds.

Instead of using a classifier neural network, RuneRing converts IMU data to points in 24-dimensional space. Detecting shapes is done with a statistical check. The result is a fast and highly versatile system that can detect a new shape with as few as five samples.

Hackaday Links: September 15, 2024

September 15, 2024 by Dan Maloney 10 Comments

A quick look around at any coffee shop, city sidewalk, or sadly, even at a traffic light will tell you that people are on their phones a lot. But exactly how much is that? For Americans in 2023, it was a mind-boggling 100 trillion megabytes, according to the wireless industry lobbying association CTIA. The group doesn’t discuss their methodology in the press release, so it’s a little hard to make judgments on that number’s veracity, or the other numbers they bandy about, such as the 80% increase in data usage since 2021, or the fact that 40% of data is now going over 5G connections. Some of the numbers are more than a little questionable, too, such as the claim that 330 million Americans (out of a current estimate of 345.8 million people) are covered by one or more 5G networks. Even if you figure that most 5G installations are in densely populated urban areas, 95% coverage seems implausible given that in 2020, 57.5 million people lived in rural areas of the USA. Regardless of the details, it remains that our networks are positively humming with data, and keeping things running is no mean feat.

Hackaday Podcast Episode 288: Cyanotypes, Antique 21-Segment Displays, And The Voynich Manuscript In A New Light

September 13, 2024 by Dan Maloney No comments

It’s Friday the 13th, and despite having to dodge black cats and poorly located ladders, Elliot and Dan were able to get together and run down the best hacks of the first week of September. Our luck was pretty good, too, seeing how we stumbled upon a coffee table that walks your drink over to you on Strandbeest legs, a potato that takes passable photographs, and a cool LED display three times better than a boring old seven-segment.

If you’ve never heard of the Voynich manuscript, you’re in luck too, because we got a chance to look inside this medieval comic book literally, with multispectral analysis. Is your cruise ship too short? No worries, just lop it in two and add a section. Speaking of cutting things up, that’s what you need to do to see how your plus-size DIY rocket engine performed after test firing.

And finally, it was a sweep for Jenny this week with our “Can’t Miss” articles, where she both pines for a simpler, smaller web experience and wonders what the future holds for biomass fuels.

This Week In Security: Malicious Rollback, WHOIS, And More

September 13, 2024 by Jonathan Bennett 4 Comments

It’s time to talk about Microsoft’s patch Tuesday, and the odd vulnerability rollback that happened. CVE-2024-43491 has caught some attention, as it’s a 9.8 on the CVSS scale, is under active exploitation, and results in Remote Code Execution (RCE). Yikes, it sounds terrible!

First off, what actually happened? The official statement is that “build version numbers crossed into a range that triggered a code defect”. We don’t know the exact details, but it’s something like an unsigned integer that was interpreted as a signed integer. A build number could have rolled over 32767, and what was intended to be 32768 or higher suddenly became −32767. Lots of “if greater than or equal” logic breaks down in that situation. Because of a logic flaw like this, certain versions of Windows 10 were unintentionally opting out of some historical security fixes.

And that’s where the high CVSS score and active exploitation descriptor comes from. This is simply the highest score of the resurgent flaws, and an acknowledgement that they have been exploited in the past. The good news is that this only applies to Windows 10 build 1507, so either the original install without any of the major updates installed, or one of the Windows 10 Enterprise Long-Term Servicing Branch (LTSB) versions. It seems that the March 2024 monthly security update introduced the problem, and it wasn’t fixed until this month’s updates.

FLOSS Weekly Episode 800: Champagning The Ladybird Browser

September 11, 2024 by Jonathan Bennett 5 Comments

This week Jonathan Bennett and Aaron Newcomb chat with Andreas Kling about Ladybird, the new browser in development from the ground up. It was started as part of SerenityOS, and has since taken on a life of its own. How much of the web works on it? How many people are working on the project? And where’s the download button? Listen to find out!
