Visual Mandela Effect: You Don’t Know Iconic Images As Well As You Think

Pop quiz, hotshot: does the guy on the Monopoly box (standard edition) wear a monocle? Next question: does the Fruit of the Loom logo involve a cornucopia? And finally, does Pikachu have a black-tipped tail? If you answered yes to any of these, I am sad to say that you are wrong, wrong, wrong.

So, what’s the deal? These are all examples of the visual version of the Mandela effect (VME), which is named after the common misconception/mass false memory that anti-Apartheid activist Nelson Mandela died decades ago in prison, despite leading South Africa in the latter half of the ’90s and living until 2013. Many people even claim having seen TV coverage of his funeral, or say they learned about his death in school during Black History Month. The whole thing has VICE wondering whether CERN is causing these mass delusions somehow with the LHC.

The more attention VME gets, the more important it seems to be to study it and try to come to some conclusion. To that end, University of Chicago researchers Deepasri Prasad and Wilma A. Bainbridge submitted an interesting and quite readable study earlier this year purporting that the VME is ‘evidence for shared and specific false memories across people’. In the study, they conducted four experiments using crowd-sourced task completion services.

Hackaday Links: August 28, 2022

The countdown for the first step on humanity’s return to the Moon has begun. The countdown for Artemis 1 started on Saturday morning, and if all goes well, the un-crewed Orion spacecraft atop the giant Space Launch Systems (SLS) booster will liftoff from the storied Pad 39B at Cape Canaveral on Monday, August 29, at 8:33 AM EDT (1233 GMT). The mission is slated to last for about 42 days, which seems longish considering the longest manned Apollo missions only lasted around 12 days. But, without the constraint of storing enough consumables for a crew, Artemis is free to take the scenic route to the Moon, as it were. No matter what your position is on manned space exploration, it’s hard to deny that launching a rocket as big as the SLS is something to get excited about. After all, it’s been 50 years since anything remotely as powerful as the SLS has headed to space, and it’s an event that’s expected to draw 100,000 people to watch it in person. We’ll have to stick to the NASA live stream ourselves; having seen a Space Shuttle launch in person in 1990, we can’t express how much we envy anyone who gets to experience this launch up close.

Hackaday Podcast 183: Stowaway Science, Cold Basements, And Warm Beers

This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos met up on a secret server to discuss the cream of this week’s crop of hacks. After gushing about the first-ever Kansas City Keyboard Meetup coming up tomorrow — Saturday the 27th, we start off by considering the considerable engineering challenge of building a knife-throwing machine, the logistics of live-streaming on the go, and the thermodynamics of split-level homes.

This week, Kristina came up with the What’s-That-Sound and managed to stump Elliot for a while, though he did eventually guess correctly after the tape stopped rolling. Think you know what it is? Then fill out the form and you’ll earn the chance to win a genuine Hackaday Podcast t-shirt!

Later in the show, we look at a macro pad that breaks the mold, an ASCII terminal like it’s 1974, and a Z80 that never was (but definitely could have been). Stick around as we root for the CubeSats hitching a ride aboard Artemis I, and at last call on the ‘cast, it’s lagers vs. ales (vs. ciders).

I3C — No Typo — Wants To Be Your Serial Bus

Remember old hard drives with their giant ribbon cables? They went serial and now the power cables are way thicker than the data cables. We’ve seen the same thing in embedded devices. Talking between chips these days tends to use I2C or SPI or some variation of these to send and receive data over a handful of pins. But now there is I3C, a relatively new industry standard that is getting a bit of traction.

I2C and SPI are mature but they do have problems. I2C can be relatively slow and SPI usually requires extra pins for each device. Besides that, there is poor support for adding and removing devices dynamically or discovering devices automatically.

I3C, created by the MIPI Alliance, aims to fix these problems. It does use the usual two wires, SCL for the clock and SDA for data.  One device acts as a controller. Other devices can be targets or secondary controllers. It is also backward compatible with I2C target devices. Depending on how you implement it, speeds can be quite fast with a raw speed of 12.5 Mbps and using line coding techniques can go to around 33 Mbps.

Space-Based Solar Power: Folly Or Stroke Of Genius?

The Sun always shines in space, unless a pesky planet gets in the way. That’s more or less the essential thought behind space-based solar power (SBSP) as newly pitched by ESA’s director general, Josef Aschbacher on Twitter. Rather than putting photovoltatic solar panels on the Earth’s surface which has this annoying property of constantly rotating said panels away from the Sun during what is commonly referred to as ‘night’, the panels would be put stationary in space, unaffected by the Earth’s rotation and weather.

Although a simple idea, it necessitates the solving of a number of problems. The obvious first question is how to get these panels up in space, hundreds of kilometers from the Earth’s surface, to create a structure many times larger than the International Space Station. The next question is how to get the power back to Earth, followed by questions about safety, maintenance, transfer losses and the inevitable economics.

With organizations ranging from NASA to China’s Academy for Space Technology (CAST), to US institutions and others involved in SBSP projects, it would seem that these problems are at the very least deemed to be solvable. This raises the question of how ESA’s most recent proposal fits into this picture. Will Europe soon be powered from orbital solar panel arrays?

How Resilient Is The Natural Gas Grid?

A few years ago, I managed to get myself on a mailing list from a fellow who fancied himself an expert on energy. Actually, it seemed that no area was beyond his expertise, and the fact that EVERY EMAIL FROM HIM CAME WITH A SUBJECT LINE IN CAPS WITH A LOT OF EXCLAMATION POINTS!!!! really sealed the deal on his bona fides. One of the facts he liked to tout was that natural gas was the perfect fuel. Not only is it clean-burning and relatively cheap, it’s also delivered directly to consumers using a completely self-powered grid. Even under “zombie apocalypse” conditions, he claimed that natural gas would continue to flow.

At the time, it seemed a bit overstated, but I figured that there was at least a nugget of truth to it — enough so that I converted from an electric range and water heater to gas-powered appliances a couple of years ago, and added gas fireplaces for supplemental heat. I just sort of took it for granted that the gas would flow, at least until the recent kerfuffle over the Nordstream pipeline. That’s when I got a look at pictures of the immense turbine compressors needed to run that pipeline, the size and complexity of which seem to put the lie to claims about the self-powered nature of natural gas grids.

Surely a system dependent on such equipment could not be entirely self-powered, right? This question and others swirled doubt in my mind, and so I did what I always do in these cases: I decided to write an article so I could look into the details. Here’s what I found out about how natural gas distribution works, at least in North America.

IBM’s Early PC Attracts Time Travelers

It wasn’t long ago I was nostalgic about an old computer I saw back in the 1980s from HP. It was sort of an early attempt at a PC, although price-wise it was only in reach for professionals. HP wasn’t the only one to try such a thing, and one of the more famous attempts was the company that arguably did get the PC world rolling: IBM. Sure, there were other companies that made PCs before the IBM PC, but that was the computer that cemented the idea of a computer on an office desk or at your home more than any computer before it. Even now, our giant supercomputer desktop machines boot as though they were a vintage 1981 PC for a few minutes on each startup. But the PC wasn’t the first personal machine from IBM and, in fact, the IBM 5100 was not only personal, but it was also portable. Well, portable by 1970s standards that also had very heavy video cameras and luggable computers like the Osborne 1.

The IBM 5100 had a brief three-year life from 1975 to 1978. A blistering 1.9 MHz 16-bit CPU drove a 5-inch CRT monitor and you could have between 16K and 64K of RAM along with a fair amount of ROM. In fact, the ROMs were the key feature and a giant switch on the front let you pick between an APL ROM and a BASIC ROM (assuming you had bought both).
