Hot on the heels of Bambu Lab’s announcement that it would be locking down all network access to its X1-series 3D printers with new firmware, the X.509 certificate and private key from the Ba…

Perhaps one of the most fascinating aspects of any developing tech scandal is the way that the target company handles criticism and feedback from the community. After announcing a new authenticatio…

In lieu of high-explosives, an exploding wire circuit can make for an interesting substitute. As [Hyperspace Pirate]

In the olden days of the WWW you could just put a robots.txt file in the root of your website and crawling bots from search engines and kin would (generally) respect the rules in it. These days, however, we have especially web crawlers from large language model (LLM) companies happily ignoring such signs on the lawn before proceeding to hover up every scrap of content on websites. Naturally this makes a lot of people very angry, but what can you do about it? The answer by [Aaron B] is Nepenthes, described on the project page as a ‘tar pit for catching web crawlers’.

With the slow demise of physical media the past years, companies are gradually closing shop on producing everything from the physical media itself to their players and recorders. For Sony this seems to have now escalated to where it’ll be shuttering its optical media storage operations completely, after more than 18 years of producing Blu-ray discs. As noted by [Toms Hardware] this also includes minidisc (MD) media and MiniDV cassettes.

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the questions that [Graham] set out to answer once and for all. He starts with an in-depth exploration of the decoupling capacitor (and related) theory. [Graham] then dives into the way that power delivery is affected by the inherent resistance, capacitance, and inductance of traces. This is the problem that decoupling capacitors are supposed to solve.

How small can an electric motor be without resorting to manufacturing methods like lithography? In a recent video, [Chronova Engineering] on YouTube tries to replicate the 1960 McLellan motor that fulfilled [Richard Feynman]’s challenge requirements. This challenge was part of [Feynman]’s

In the world of large language models (LLMs) there tend to be relatively few upsets ever since OpenAI barged onto the scene with its transformer-based GPT models a few years ago, yet now it seems that Chinese company DeepSeek has upended the status quo. Its new DeepSeek-V3 model is not only open source, it also claims to have been trained for only a fraction of the effort required by competing (open & closed source) models, while performing significantly better.

The Pebble smartwatch was introduced in 2012 as part of a Kickstarter campaign and saw moderate success before the company behind it got bought out by Fitbit. Although a group of enthusiasts kept their Pebble devices alive, including via the alternate Rebble project for online services, it seemed that no new Pebble devices would grace this Earth. However, we now got a flurry of Pebble updates, with Google, the current owner of Fitbit, open sourcing the PebbleOS source, and [Eric Migicovsky] as the original Pebble founder announcing new Pebble watches.

Transition-metal dichalcogenides ( TMDs ) are the subject of an emerging field in semiconductor research, with these materials offering a range of useful properties that include not only semiconductor applications, but also in superconducting material research and in supercapacitors. A recent number of papers have been published on these latter two applications, with [Rui] et al. demonstrating superconductivity in (InSe 2
