Happy Birthday, Sinclair ZX81 Computer!

On March 5, 1981, Sinclair Research launched the ZX81 home computer in the U.K. (It was also known as the Timex-Sinclair TS1000 in the U.S.) It came with just one kilobyte of memory, and was a self-contained unit with a rather crappy keyboard. The keyboard didn't have moving key switches; instead it used membrane buttons similar to those often used on microwave ovens.

Despite its limitations, the ZX81 was a revolution, because it cost just £49.95 in the U.K.—massively cheaper than anything else on the market. It was also available in normal retail stores, rather than specialty computer shops.

It really was the people's computer, and for many it was their introduction to home computing and computer programming. Incidentally, at that cheap price, it was a kit you assembled at home (a soldering iron was required). You'd have to pay an extra £20 if you wanted a pre-assembled unit. In the U.S., the fully-assembled unit cost $149.95.

The ZX81 was also expandable. You could upgrade it from its RAM using an external cartridge to bring it up to 16k—making it vastly more usable for real work. If you needed to store programs, you saved them on cassette tapes using a tape recorder. This was a finicky process, as you had to fiddle with the volume to get things just right...but for the price, it was unbeatable.

The ZX81/TS1000 sold millions, despite its limitations. Although it didn't take over the computing world, its serious focus on retail price made it a common computer in the early home computing market. (My family had one!) It was literally a fraction of the price of competing systems. Here's a detailed remembrance of the ZX81, showing some of what it could (and could not) do:

Here's more detail from that interview, including a discussion of the "wobbly" RAM pack:

Big Questions
What Could the Repeal of Net Neutrality Mean for Internet Users?

What could the repeal of net neutrality mean for the average American internet user?

Zouhair Belkoura:

The imminent repeal of net neutrality could have implications for Americans beyond the Internet’s stratification, increased costs to consumers, and hindered access to content for all. Net neutrality’s repeal is a threat to the Internet’s democracy—the greatest information equalizer of our time.

With net neutrality’s repeal, ISPs could be selective about the content and pricing packages they make available. Portugal is a good example of what a country looks like without net neutrality

What people may not realize is that a repeal of net neutrality would also give ISPs the ability to throttle people’s Internet traffic. Customers won’t likely have visibility into what traffic is being throttled, and it could substantially slow down people’s Internet connections.

What happens when this type of friction is introduced to the system? The Internet—the greatest collective trove of information in the world—could gradually be starved. People who experience slower Internet speeds may get frustrated and stop seeking out their favorite sites. People may also lose the ability to make choices about the content they want to see and the knowledge they seek.

Inflated pricing, less access to knowledge, and slower connections aren’t the only impact a net neutrality repeal might have. People’s personal privacy and corporations’ security may suffer, too. Many people use virtual private networks to protect their privacy. VPNs keep people’s Internet browsing activities invisible to their ISPs and others who may track them. They also help them obscure their location and encrypt online transactions to keep personal data secure. When people have the privacy that VPNs afford, they can access information freely without worrying about being watched, judged, or having their browsing activity bought and sold by third-party advertisers.

Virtual private networks are also a vital tool for businesses that want to keep their company data private and secure. Employees are often required by their employers to connect to a VPN whenever they are offsite and working remotely.

Even the best VPNs can slow down individuals' Internet connections, because they create an encrypted tunnel to protect and secure personal data. If people want to protect their personal privacy or company’s security with a VPN [they] also must contend with ISP throttling; it’s conceivable that net neutrality’s repeal could undermine people’s freedom to protect their online safety. It could also render the protection a VPN offers to individuals and companies obsolete.

Speed has always been a defining characteristic of the Internet’s accessibility and its power. Net neutrality’s repeal promises to subvert this trait. It would compromise both people's and companies’ ability to secure their personal data and keep their browsing and purchasing activities private. When people don’t have privacy, they can’t feel safe. When they don’t feel safe, they can’t live freely. That’s not a world anyone, let alone Americans, want to live in.

An AI Program Wrote Harry Potter Fan Fiction—and the Results Are Hilarious

“The castle ground snarled with a wave of magically magnified wind.”

So begins the 13th chapter of the latest Harry Potter installment, a text called Harry Potter and the Portrait of What Looked Like a Large Pile of Ash. OK, so it’s not a J.K. Rowling original—it was written by artificial intelligence. As The Verge explains, the computer-science whizzes at Botnik Studios created this three-page work of fan fiction after training an algorithm on the text of all seven Harry Potter books.

The short chapter was made with the help of a predictive text algorithm designed to churn out phrases similar in style and content to what you’d find in one of the Harry Potter novels it "read." The story isn’t totally nonsensical, though. Twenty human editors chose which AI-generated suggestions to put into the chapter, wrangling the predictive text into a linear(ish) tale.

While magnified wind doesn’t seem so crazy for the Harry Potter universe, the text immediately takes a turn for the absurd after that first sentence. Ron starts doing a “frenzied tap dance,” and then he eats Hermione’s family. And that’s just on the first page. Harry and his friends spy on Death Eaters and tussle with Voldemort—all very spot-on Rowling plot points—but then Harry dips Hermione in hot sauce, and “several long pumpkins” fall out of Professor McGonagall.

Some parts are far more simplistic than Rowling would write them, but aren’t exactly wrong with regards to the Harry Potter universe. Like: “Magic: it was something Harry Potter thought was very good.” Indeed he does!

It ends with another bit of prose that’s not exactly Rowling’s style, but it’s certainly an accurate analysis of the main current that runs throughout all the Harry Potter books. It reads: “‘I’m Harry Potter,’ Harry began yelling. ‘The dark arts better be worried, oh boy!’”

Harry Potter isn’t the only work of fiction that Jamie Brew—a former head writer for ClickHole and the creator of Botnik’s predictive keyboard—and other Botnik writers have turned their attention to. Botnik has previously created AI-generated scripts for TV shows like The X-Files and Scrubs, among other ridiculous machine-written parodies.
