Computers! They’re in everything these days. Everything from thermostats to fridges and even window blinds are now on the Internet, and that makes them all ripe for hacking.
Electric vehicle chargers are becoming a part of regular life. They too are connected devices, and thus pose a security risk if not designed and maintained properly. As with so many other devices on the Internet of Things, the truth is anything but.

We’ve all looked up things on Wikipedia and, generally, it is usually correct information. However, the fact that anyone can edit it leads to abuse and makes it somewhat unreliable. Case in point? The BBC’s [Marco Silva] has the story of the great online toaster hoax which erroneously identified the inventor of the toaster with great impact.
You should read the original story, but in case you want a synopsis, here goes: Until recently, the Wikipedia entry for toasters stated that a Scottish man named Alan MacMasters invented the electric toaster in the 1800s. Sounds plausible. Even more so because several books had picked it up along with the Scottish government’s Brand Scottland website. At least one school had a day memorializing the inventor and a TV show also honored him with a special dessert named for Alan MacMasters, the supposed inventor.

There were news stories afoot this week with somewhat breathless headlines that suggested a medical breakthrough was at hand: “In a 1st, two people receive transfusions of lab-grown blood cells.” A headline like that certainly catches the eye, especially as the holidays approach and the inevitable calls for increased blood donations that always seem to happen this time of year as the supply gets pinched. Does a headline like that mean that someone is working on completely artificial blood?
As always with this sort of thing, the answer is a mixed bag. Yes, a team in the UK has transfused two patients with a small amount of lab-grown red blood cells, and it’s the first time that particular procedure has been performed. But while the headline is technically correct, the amount transfused was very small, so the day when lab-grown whole blood transfusions replace donated blood isn’t exactly here yet. But the details of what was done and why it was attempted are the really interesting part here, and it’s worth a deep dive because it does potentially point the way to a future where totally synthetic blood may be a real thing.

Once upon a time, countries protected their domestic industries with tariffs on imports. This gave the home side a price advantage over companies operating overseas, but the practice has somewhat fallen out of fashion in the past few decades.
These days, governments are altogether more creative, using fancy export controls to protect their interests. To that end, the United States enacted an export restriction on high-powered computing devices. In response, Chinese designers are attempting to artificially slow their hardware to dodge these rules.

As far as interesting problems go, few can really compete with the perennial question: “Are we alone?” The need to know if there are other forms of intelligent life out there in the galaxy is deeply rooted, and knowing for sure either way would have massive implications.
But it’s a big galaxy, and knowing where to look for signals that might mean we’re not alone is a tough task. Devoting limited and expensive resources to randomly listen to chunks of the sky in the hopes of hearing something that’s obviously made by a technical civilization is unlikely to bear fruit. Much better would be to have something to base sensible observations on — some kind of target that has a better chance of paying off.
Luckily, a chance observation nearly 50 years ago has provided just that. The so-called Wow! Signal, much discussed but only occasionally and somewhat informally studied, has provided a guidepost in the sky, thanks in part to a citizen scientist with a passion for finding exoplanets.
A footnote in the week’s technology news came from Linus Torvalds, as he floated the idea of abandoning support for the Intel 80486 architecture in a Linux kernel mailing list post. That an old and little-used architecture might be abandoned should come as no surprise, it’s a decade since the same fate was meted out to Linux’s first platform, the 80386. The 486 line may be long-dead on the desktop, but since they are not entirely gone from the embedded space and remain a favourite among the retrocomputer crowd it’s worth taking a minute to examine what consequences if any there might be from this move.
The Intel 80486 was released in 1989, and was substantially an improved version of their previous 80386 line of 32-bit microprocessors with an on-chip cache, more efficient pipelining, and a built-in mathematical co-processor. It had a 32-bit address space, though in practice the RAM and motherboard constraints of the 1990s meant that a typical 486 system would have RAM in megabyte quantities. There were a range of versions in clock speeds from 16 MHz to 100 MHz over its lifetime, and a low-end “SX” range with the co-processor disabled. It would have been the object of desire as a processor on which to run WIndows 3.1 and it remained a competent platform for Windows 95, but by the end of the ’90s its days on the desktop were over. Intel continued the line as an embedded processor range into the 2000s, finally pulling the plug in 2007. The 486 story was by no means over though, as a range of competitors had produced their own take on the 486 throughout its active lifetime. The non-Intel 486 chips have outlived the originals, and even today in 2022 there is more than one company making 486-compatible devices. RDC produce a range of RISC SoCs that run 486 code, and according to the ZF Micro Solutions website they still boast of an SoC that is a descendant of the Cyrix 486 range. There is some confusion online as to whether DM&P’s Vortex86 line are also 486 derivatives, however we understand them to be descendants of Rise Technology’s Pentium clone.

Robots are used in all sorts of industries on a wide variety of tasks. Typically, it’s because they’re far faster, more accurate, and more capable than we are. Expert humans could not compete with the consistent, speedy output of a robotic welder on an automotive production line, nor could they as delicately coat the chocolate on the back of a KitKat.
However, there are some tasks in which humans still have the edge. Those include driving, witty repartee, and yes, folding laundry. That’s not to say the robots aren’t trying, though, so let’s take a look at the state of the art.
