How Regulations Are Trying To Keep Home Battery Installs Safe

September 24, 2025 by Lewin Day 81 Comments

The advent of rooftop solar power generation was a huge step forward for renewable energy. No longer was generating electricity the sole preserve of governments and major commercial providers; now just about any homeowner could start putting juice into the grid for a few thousand dollars. Since then, we’ve seen the rise of the home battery, which both promises to make individual homes more self sufficient, whilst also allowing them to make more money selling energy to the grid where needed.

Home batteries are becoming increasingly popular, but as with any new home utility, there come risks. After all, a large capacity battery can present great danger if not installed or used correctly. In the face of these dangers, authorities in jurisdictions around the world have been working to ensure home batteries are installed with due regard for the safety of the occupants of the average home.

The Impending CRT Display Revival Will Be Televised

September 23, 2025 by Maya Posch 112 Comments

Until the 2000s vacuum tubes practically ruled the roost. Even if they had surrendered practically fully to semiconductor technology like integrated circuits, there was no escaping them in everything from displays to video cameras. Until CMOS sensor technology became practical, proper video cameras used video camera tubes and well into the 2000s you’d generally scoff at those newfangled LC displays as they couldn’t capture the image quality of a decent CRT TV or monitor.

For a while it seemed that LCDs might indeed be just a flash in the pan, as it saw itself competing not just with old-school CRTs, but also its purported successors in the form of SED and FED in particular, while plasma TVs made home cinema go nuts for a long while with sizes, fast response times and black levels worth their high sale prices.

We all know now that LCDs survived, along with the newcomer in OLED displays, but despite this CRTs do not feel like something we truly left behind. Along with a retro computing revival, there’s an increasing level of interest in old-school CRTs to the point where people are actively prowling for used CRTs and the discontent with LCDs and OLED is clear with people longing for futuristic technologies like MicroLED and QD displays to fix all that’s wrong with today’s displays.

Could the return of CRTs be nigh in some kind of format?

Meta’s Ray-Ban Display Glasses And The New Glassholes

September 22, 2025 by Maya Posch 134 Comments

It’s becoming somewhat of a running gag that any device or object will be made ‘smart’ these days, whether it’s a phone, TV, refrigerator, home thermostat, headphones or glasses. This generally means somehow cramming a computer, display, camera and other components into the unsuspecting device, with the overarching goal of somehow making it more useful to the user and not impacting its basic functionality.

Although smart phones and smart TVs have been readily embraced, smart glasses have always been a bit of a tough sell. Part of the problem here is of course that most people do not generally wear glasses, between people whose vision does not require correction and those who wear e.g. contact lenses. This means that the market for smart glasses isn’t immediately obvious. Does it target people who wear glasses anyway, people who wear sunglasses a lot, or will this basically move a smart phone’s functionality to your face?

Smart glasses also raise many privacy concerns, as their cameras and microphones may be recording at any given time, which can be unnerving to people. When Google launched their Google Glass smart glasses, this led to the coining of the term ‘glasshole‘ for people who refuse to follow perceived proper smart glasses etiquette.

This Week In Security: The Shai-Hulud Worm, ShadowLeak, And Inside The Great Firewall

September 19, 2025 by Jonathan Bennett 7 Comments

Hardly a week goes by that there isn’t a story to cover about malware getting published to a repository. Last week it was millions of downloads on NPM, but this week it’s something much more concerning. Malware published on NPM is now looking for NPM tokens, and propagating to other NPM packages when found. Yes, it’s a worm, jumping from one NPM package to another, via installs on developer machines.

It does other things too, like grabbing all the secrets it can find when installed on a machine. If the compromised machine has access to a Github account, a new repo is created named Shai-Hulud, borrowed from the name of the sandworms from Dune. The collected secrets and machine info gets uploaded here, and a workflow also uploads any available GitHub secrets to the webhook.site domain.

How many packages are we talking about? At least 187, with some reports of over 500 packages compromised. The immediate attack has been contained, as NPM has worked to remove the compromised packages, and apparently has added filtering code that blocks the upload of compromised packages.

So far there hasn’t been an official statement on the worm from NPM or its parent companies, GitHub or Microsoft. Malicious packages uploaded to NPM is definitely nothing new. But this is the first time we’ve seen a worm that specializes in NPM packages. It’s not a good step for the trustworthiness of NPM or the direct package distribution model.

Radio Apocalypse: Clearing The Air With SCATANA

September 18, 2025 by Dan Maloney 7 Comments

For the most part, the Radio Apocalypse series has focused on the radio systems developed during the early days of the atomic age to ensure that Armageddon would be as orderly an affair as possible. From systems that provided backup methods to ensure that launch orders would reach the bombers and missiles, to providing hardened communications systems to allow survivors to coordinate relief and start rebuilding civilization from the ashes, a lot of effort went into getting messages sent.

Strangely, though, the architects of the end of the world put just as much thought into making sure messages didn’t get sent. The electronic village of mid-century America was abuzz with signals, any of which could be abused by enemy forces. CONELRAD, which aimed to prevent enemy bombers from using civilian broadcast signals as navigation aids, is a perfect example of this. But the growth of civil aviation through the period presented a unique challenge, particularly with the radio navigation system built specifically to make air travel as safe and reliable as possible.

Balancing the needs of civil aviation against the possibility that the very infrastructure making it possible could be used as a weapon against the U.S. homeland is the purpose of a plan called Security Control of Air Traffic and Air Navigation Aids, or SCATANA. It’s a plan that cuts across jurisdictions, bringing military, aviation, and communications authorities into the loop for decisions regarding when and how to shut down the entire air traffic system, to sort friend from foe, to give the military room to work, and, perhaps most importantly, to keep enemy aircraft as blind as possible.

A New Generation Of Spacecraft Head To The ISS

September 18, 2025 by Tom Nardi 22 Comments

While many in the industry were at first skeptical of NASA’s goal to put resupply flights to the International Space Station in the hands of commercial operators, the results speak for themselves. Since 2012, the SpaceX Dragon family of spacecraft has been transporting crew and cargo from American soil to the orbiting laboratory, a capability that the space agency had lost with the retirement of the Space Shuttle. Putting these relatively routine missions in the hands of a commercial provider like SpaceX takes some of the logistical and financial burden off of NASA, allowing them to focus on more forward-looking projects.

But as the saying goes, you should never put all of your eggs in one basket. As successful as SpaceX has been, there’s always a chance that some issue could temporarily ground either the Falcon 9 or the Dragon.

While Russia’s Progress and Soyuz vehicles would still be available in an emergency situation, it’s in everyone’s best interest that there be multiple backup vehicles that can bring critical supplies to the Station.

Which is precisely why several new or upgraded spacecraft, designed specifically for performing resupply missions to the ISS and any potential commercial successor, are coming online over the next few years.

In fact, one of them is already flying its first mission, and will likely have arrived at the International Space Station by the time you read this article.
