Quantum supremacy and post-quantum crypto

Google announced today that it has demonstrated “quantum supremacy,” i.e. that they have solved a problem on a quantum computer that could not be solved on a classical computer. Google says Our machine performed the target computation in 200 seconds, and from measurements in our experiment we determined that it would take the world’s fastest supercomputer 10,000 years to produce a similar output. IBM disputes this claim. They don’t dispute that Google has computed something with a quantum computer that would take a lot of conventional computing power, only that…

Scrape the Web with scrapestack (Sponsored)

I first grew to love Firefox not as a web developer but as user, and what drew me to this amazing new browser was its add-on ecosystem. The add-on I used the most? Web scrapers.

These days writing scrapers, even as a seasoned software engineer, is a nightmare. Storage, CAPTCHA, DDOS/Proxies…to protect our sites we’ve killed the generic scraper on a large scale level. These days…

How to Create a QR Code

QR codes aren’t everyone’s cup of tea but I quite like them. If I see something I want to remember or check out later, especially when on the road, it’s super easy to take a quick picture — it’s much easier than trying to remember a URL and much faster than typing it in on a tiny keyboard. If you need to generate QR codes, for a client or yourself, there’s a really nice JavaScript project: node-qrcode. Let’s look at the different wys and output formats you can use to…
