Will RadioShack Return?

September 8, 2023 by Al Williams 145 Comments

We suspect that if you want to write a blockbuster movie or novel, the wrong approach is to go to a studio or publisher and say, “I have this totally new idea that is like nothing you’ve ever seen before…” Even Star Trek was pitched to the network as “Wagon Train to the stars.” People with big money tend to want to bet on things that have succeeded before, which is why so many movies are either remakes or Star Trek XXII: The Search for 4 PM Dinner Specials. Maybe that’s what the El Salvador-based Unicomer Group had in mind when they bought one of our favorite brands, RadioShack. They are reportedly planning a major comeback for the beleaguered brand both online and in the physical world.

In all fairness, the Shack may be better in our memories than in our realities. It was handy to stop off and pick up a coax connector, even if it cost three times the going rate for one. There was a time when RadioShack offered reasonable parts for projects, and it seems like near the end, they tried to hit that target again, but for many years, you could not find the typical parts for a modern project there anyway. However, Unicomer isn’t just a random group of investors.

Liberté, égalité, Fraternité: France Loses Its Marbles On Internet Censorship

August 22, 2023 by Jenny List 77 Comments

Over the years we’ve covered a lot of attempts by relatively clueless governments and politicians to enact think-of-the-children internet censorship or surveillance legislation, but there’s a law from France in the works which we think has the potential to be one of the most sinister we’ve seen yet.

It flew under our radar so we’re grateful to [0x1b5b] for bringing it to our attention, and it concerns a proposal to force browser vendors to incorporate French government censorship and spyware software in their products. We’re sure that most of our readers will understand the implications of this, but for anyone not versed in online privacy and censorship this is a level of intrusion not even attempted by China in its state surveillance programme. Perhaps most surprisingly in a European country whose people have an often-fractious relationship with their government, very few French citizens seem to be aware of it or what it means.

It’s likely that if they push this law through it will cause significant consternation over the rest of the European continent. We’d expect those European countries with less liberty-focused governments to enthusiastically jump on the bandwagon, and we’d also expect the European hacker community to respond with a plethora of ways for their French cousins to evade the snooping eyes of Paris. We have little confidence in the wisdom of the EU parliament in Brussels when it comes to ill-thought-out laws though, so we hope this doesn’t portend a future dark day for all Europeans. We find it very sad to see in any case, because France on the whole isn’t that kind of place.

The World ID Orb And The Question Of What Defines A Person

August 10, 2023 by Maya Posch 68 Comments

Among the daily churn of ‘Web 3.0’, blockchains and cryptocurrency messaging, there is generally very little that feels genuinely interesting or unique enough to pay attention to. The same was true for OpenAI CEO Sam Altman’s Ethereum blockchain-based Worldcoin when it was launched in 2021 while promising many of the same things as Bitcoin and others have for years. However, with the recent introduction of the World ID protocol by Tools for Humanity (TfH) – the company founded for Worldcoin by Mr. Altman – suddenly the interest of the general public was piqued.

Defined by TfH as a ‘privacy-first decentralized identity protocol’ World ID is supposed to be the end-all, be-all of authentication protocols. Part of it is an ominous-looking orb contraption that performs iris scans to enroll new participants. Not only do participants get ‘free’ Worldcoins if they sign up for a World ID enrollment this way, TfH also promises that this authentication protocol can uniquely identify any person without requiring them to submit any personal data, only requiring a scan of your irises.

Essentially, this would make World ID a unique ID for every person alive today and in the future, providing much more security while preventing identity theft. This naturally raises many questions about the feasibility of using iris recognition, as well as the potential for abuse and the impact of ocular surgery and diseases. Basically, can you reduce proof of personhood to an individual’s eyes, and should you?

Review: Beepy, A Palm-sized Linux Hacking Playground

August 7, 2023 by Tom Nardi 45 Comments

In the long ago times, when phones still flipped and modems sang proudly the songs of their people, I sent away for a set of Slackware CDs and embarked on a most remarkable journey. Back then, running Linux (especially on the desktop) was not a task to be taken lightly. The kernel itself was still in considerable flux — instead of changing some obscure subsystem or adding support for a niche gadget you don’t even own, new releases were unlocking critical capabilities and whole categories of peripherals. I still remember deciding if I wanted to play it safe and stick with my current kernel, or take a chance on compiling the latest version to check out this new “USB Mass Storage” thing everyone on the forums was talking about…

But modern desktop Linux has reached an incredible level of majority, and is now a viable choice for a great number of computer users. In fact, if you add Android and Chrome OS into the mix, there are millions and millions of people who are using Linux on daily basis and don’t even realize it. These days, the only way to experience that sense of adventure and wonderment that once came pre-loaded with a Linux box is to go out and seek it.

Which is precisely how it feels using using the Beepy from SQFMI. The handheld device, which was formerly known as the Beepberry before its creators received an all-too-predicable formal complaint, is unabashedly designed for Linux nerds. Over the last couple of weeks playing with this first-run hardware, I’ve been compiling kernel drivers, writing custom scripts, and trying (though not always successfully) to get new software installed on it. If you’re into hacking around on Linux, it’s an absolute blast.

There’s a good chance that you already know if the Beepy is for you or not, but if you’re still on the fence, hopefully this in-depth look at the hardware and current state of the overall project can help you decide before SQFMI officially starts taking new orders for the $79 gadget.

LK-99: Diamagnetc Semiconductor, Not Superconductor?

August 5, 2023 by Jenny List 70 Comments

Every so often, along comes a story which, like [Fox Mulder] with his unexplained phenomena, we want to believe. EM drives and cold fusion for example would be the coolest of the cool if they worked, but sadly they crumbled when subjected to scientific inquiry outside the labs of their originators. The jury’s still out on the latest example, a claimed room-temperature superconductor, but it’s starting to seem that it might instead be a diamagnetic semiconductor.

We covered some of the story surrounding the announcement of LK-99 and subsequent reports of it levitating under magnetic fields, but today’s installment comes courtesy of a team from Beihang University in Beijing. They’ve published a paper in which they characterize their sample of LK-99, and sadly according to them it’s no superconductor.

Instead it’s a diamagnetic semiconductor, something that in itself probably bears some explanation. We’re guessing most readers will be familiar with semiconductors, but diamagnetic substances possess the property of having an external magnetic field induce an internal magnetic field in the opposite direction. This means that they will levitate in a magnetic field, but not due to the Meissner effect, the property of superconductors which causes magnetic field to flow round their outside. The Beijing team have shown by measuring the resistance of the sample that it’s not a superconductor.

So sadly it seems LK-99 isn’t the miracle it was billed as, unless there’s some special quirk in the production of the original Korean sample which didn’t make it to the other teams. We can’t help wondering why a sample from Korea wasn’t subjected to external evaluation rather than leaving the other teams to make their own. Never mind, eh!

Ask Hackaday: What’s The Deal With Humanoid Robots?

July 31, 2023 by Lewin Day 43 Comments

When the term ‘robot’ gets tossed around, our minds usually race to the image of a humanoid machine. These robots are a fixture in pop culture, and often held up as some sort of ideal form.

Yet, one might ask, why the fixation? While we are naturally obsessed with recreating robots in our own image, are these bipedal machines the perfect solution we imagine them to be?

The British Government Is Coming For Your Privacy

July 30, 2023 by Jenny List 77 Comments

The list of bad legislation relating to the topic of encryption and privacy is long and inglorious. Usually, these legislative stinkers only affect those unfortunate enough to live in the country that passed them. Still, one upcoming law from the British government should have us all concerned. The Online Safety Bill started as the usual think-of-the-children stuff, but as the EFF notes, some of its proposed powers have the potential to undermine encryption worldwide.

At issue is the proposal that services with strong encryption incorporate government-sanctioned backdoors to give the spooks free rein to snoop on communications. We imagine that this will be of significant interest to some of the world’s less savoury regimes, a club we can’t honestly say the current UK government doesn’t seem hell-bent on joining. The Bill has had a tumultuous passage through the Lords, the UK upper house, but PM Rishi Sunak’s administration has proved unbending.

If there’s a silver lining to this legislative train wreck, it’s that many of the global tech companies are likely to pull their products from the UK market rather than comply. We understand that UK lawmakers are partial to encrypted online messaging platforms. Thus, there will be poetic justice in their voting once more for a disastrous bill with the unintended consequence of taking away something they rely on.
