Meet the quantum blockchain that works like a time machine

A new — and theoretical — system for blockchain-based data storage could ensure that hackers will not be able to crack cryptocurrencies once the quantum era starts. The idea, proposed by researchers at the Victoria University of Wellington in New Zealand, would secure cryptocurrency futures for decades using a blockchain technology that is like a time machine. You can check out their findings here. To understand what’s going on here we have to define some terms. A blockchain stores every transaction in a system on what amounts to an immutable…

Unstoppable exploit in Nintendo Switch opens door to homebrew and piracy

The Nintendo Switch may soon be a haven for hackers, but not the kind that want your data — the kind that want to run SNES emulators and Linux on their handheld gaming consoles. A flaw in an Nvidia chip used by the Switch, detailed today, lets power users inject code into the system and modify it however they choose. The exploit, known as Fusée Gelée, was first hinted at by developer Kate Temkin a few months ago. She and others at ReSwitched worked to prove and document the exploit,…

This robot can build your IKEA furniture

There are two kinds of people in the world: those who hate building IKEA furniture and madmen. Now, thanks to IkeaBot, the madmen can be replaced. IkeaBot is a project built at Control Robotics Intelligence (CRI) group at NTU in Singapore.

The results, if you’ve ever fought with someone trying to put together a Billy, are heartening. From Spectrum: The assembly process…

Don’t just stir; Stircle

Although I do my best to minimize the trash produced by my lifestyle (blog posts notwithstanding), one I can’t really control, at least without carrying a spoon on my person at all times, is the necessity of using a disposable stick to stir my coffee. That could all change with the Stircle, a little platform that spins your drink around to mix it. Now, of course this is ridiculous. And there are other things to worry about. But honestly, the scale of waste here is pretty amazing. Design house Amron…

Cameras found in smart homes or wearables need to transmit HD video, but it takes a lot of power to process that video and…

Teased as part of the company’s 40th anniversary, the shrouded gadget definitely doesn’t look like a NEO-GEO, or even a NEO-GEO Pocket. Gizmodo notes that the description mentions a “new game machine,” but no details beyond that. The tall, boxy outline suggests a…
