Vintage Computer Festival East Was A Retro Madhouse

April 19, 2023 by Tom Nardi 36 Comments

The Vintage Computer Festival East took place last weekend at the InfoAge Science and History Museum in New Jersey, and by any metric you care to use, it was a phenomenal success. Everyone you spoke with, from the the exhibitors and attendees, to the veteran volunteers who put this incredible show together, all said the same thing: they’d never seen a turnout like this before.

Of course, such success is not without cost. The exhibit rooms were so packed that moving through them was a challenge, the line to get food or browse the consignment area occasionally stretched outside the building, and at one point the event’s electronic payment system buckled under the pressure.

Yet even the folks who waited the better part of an hour to rummage through boxes of dusty treasures, only to find themselves left standing with armfuls of heavy gear they couldn’t pay for until the technical issues were resolved couldn’t really complain. I should know, I was one of them. It would be like going to a concert and getting upset that the music was too loud — the event was advertised as a festival, and that’s exactly what it was.

No matter where you went, you’d find throngs of excited people who were eager to chat about the golden age of computing. So even if you were stuck in a long line, or had to step outside of the exhibit area to get some fresh air, you were always in excellent company. Seeing such a large and diverse number of people come out for what’s ultimately a niche event was exceptionally gratifying. At the end of the day, if the price we have to pay for this kind of community response is a few long lines and tight squeezes, it’s well worth it.

Each time I cover an event like this for Hackaday, I do so with the caveat that there’s really no substitute for being there in person. No matter how many articles you read and YouTube recaps you watch, you’ll never be able to see all the things you would have had you been able to walk the show floor yourself. It’s a bit like exploring the Moon or Mars: remotely controlled robots are capable of capturing terabytes of data and beaming it back to Earth, but even still, there’s the potential to learn so much more by putting boots on the ground.

The same is true of VCF East 2023 — what I bring you here is just the tip of the iceberg in terms of what was on display at this year’s event. On the other hand, you have the advantage of being able to peruse these images without having to stand in line. Is it worth the trade? Only you can be the judge of that. But for my money, I’ll gladly get back in line when VCF East 2024 rolls around.

How Tattoos Interact With The Immune System Could Have Impacts For Vaccines

April 5, 2023 by Lewin Day 40 Comments

Tattoos are an interesting technology. They’re a way of marking patterns and designs on the skin that can last for years or decades. All this, despite the fact that our skin sloughs off on a regular basis!

As it turns out, tattoos actually have a deep and complex interaction with our immune system, which hold some of the secrets regarding their longevity. New research has unveiled more insight into how the body responds when we get inked up.

The Liquid Trees Of Belgrade: The Facts Behind The Furore

April 4, 2023 by Lewin Day 126 Comments

Historically, nature has used trees to turn carbon dioxide back into oxygen for use by living creatures. The trees play a vital role in the carbon cycle, and have done so for millennia. Recently, humans have thrown things off a bit by getting rid of lots of trees and digging up a lot more carbon.

While great efforts are underway to replenish the world’s tree stocks, Belgrade has gone in a different direction, creating artificial “liquid trees” to capture carbon dioxide instead. This has spawned wild cries of dystopia and that the devices are an affront to nature. Let’s sidestep the hysteria and look at what’s actually going on.

Europe’s Proposed Right-To-Repair Law: A Game Changer, Or Business As Usual?

March 27, 2023 by Maya Posch 145 Comments

Recently, the European Commission (EC) adopted a new proposal intended to enable and promote the repair of a range of consumer goods, including household devices like vacuum cleaners and washing machines, as well as electronic devices such as smartphones and televisions. Depending on how the European Parliament and Council vote in the next steps, this proposal may shape many details of how devices we regularly interact with work, and how they can be repaired when they no longer do.

As we have seen recently with the Digital Fair Repair Act in New York, which was signed into law last year, the devil is as always in the details. In the case of the New York bill, the original intent of enabling low-level repairs on defective devices got hamstrung by added exceptions and loopholes that essentially meant that entire industries and types of repairs were excluded. Another example of ‘right to repair’ being essentially gamed involves Apple’s much-maligned ‘self repair’ program, that is both limited and expensive.

So what are the chances that the EU will succeed where the US has not?

Gordon Moore, 1929 — 2023

March 25, 2023 by Jenny List 16 Comments

The news emerged yesterday that Gordon Moore, semiconductor pioneer, one of the founders of both Fairchild Semiconductor and Intel, and the originator of the famous Moore’s Law, has died. His continuing influence over all aspects of the technology which makes our hardware world cannot be overstated, and his legacy will remain with us for many decades to come.

A member of the so-called “Traitorous Eight” who left Shockley Semiconductor in 1957 to form Fairchild Semiconductor, he and his cohort laid the seeds for what became Silicon Valley and the numerous companies, technologies, and products which have flowed from that. His name is probably most familiar to us through “Moore’s Law,” the rate of semiconductor development he first postulated in 1965 and revisited a decade later, that establishes a doubling of integrated circuit component density every two years. It’s a law that has seemed near its end multiple times over the decades since, but successive advancements in semiconductor fabrication technology have arrived in time to maintain it. Whether it will continue to hold from the early 2020s onwards remains a hotly contested topic, but we’re guessing its days aren’t quite over yet.

Perhaps Silicon Valley doesn’t hold the place in might once have in the world of semiconductors, as Uber-for-cats app startups vie for attention and other semiconductor design hubs worldwide steal its thunder. But it’s difficult to find a piece of electronic technology, whether it was designed in Mountain View, Cambridge, Shenzhen, or wherever, that doesn’t have Gordon Moore and the rest of those Fairchild founders in its DNA somewhere. Our world is richer for their work, and that’s what we’ll remember Gordon Moore for.

You can read our thoughts on Moore’s famous law. If you ever wondered how Silicon Valley became the place for electronics, the story is probably much older than you think.

Plan To Jam Mobile Phones In Schools Is Madness

March 24, 2023 by Lewin Day 329 Comments

Mobile phones in schools. If you’re a teacher, school staffer, or a parent, you’ve likely got six hundred opinions about this very topic, and you will have had six hundred arguments about it this week. In Australia, push has come to shove, and several states have banned the use of mobile phones during school hours entirely. Others are contemplating doing the same.

In the state of New South Wales, the current opposition party has made it clear it will implement a ban if elected. Wildly, the party wants to use mobile phone jamming technology to enforce this ban whether students intend to comply or not. Let’s take a look at how jammers work in theory, and explore why using them in schools would be madness in practice.

The Rise And (Eventual) Fall Of The SIM Card

March 20, 2023 by Tom Nardi 109 Comments

There are few devices that better exemplify the breakneck pace of modern technical advancement than the mobile phone. In the span of just a decade, we went from flip phones and polyphonic ringtones to full-fledged mobile computers with quad-core processors and gigabytes of memory.

While rapid advancements in computational power are of course nothing new, the evolution of mobile devices is something altogether different. The Razr V3 of 2003 and the Nexus 5 of 2013 are so vastly different that it’s hard to reconcile the fact they were (at least ostensibly) designed to serve the same purpose — with everything from their basic physical layout to the way the user interacts with them having undergone dramatic changes in the intervening years. Even the network technology they use to facilitate voice and data communication are different.

Yet, there’s at least one component they share: the lowly SIM card. In fact, if you don’t mind trimming a bit of unnecessary plastic away, you could pull the SIM out of the Razr and slap it into the Nexus 5 without a problem. It doesn’t matter that the latter phone wasn’t even a twinkling in Google’s eye when the card was made, the nature of the SIM card means compatibility is a given.

Indeed there’s every reason to believe that very same card, now 20 years old, could be installed in any number of phones on the market today. Although, once again, some minor surgery would be required to pare it down to size.

Such is the beauty of the SIM, or Subscriber Identity Module. It allows you to easily transfer your cellular service from one phone to another, with little regard to the age or manufacturer of the device, and generally without even having to inform your carrier of the swap. It’s a simple concept that has served us well for almost as long as cellular telephones have existed, and separates the phone from the phone contract.

So naturally, there’s mounting pressure in the industry to screw it up.
