Why Deep Frying Turkey Can Go Very Wrong

November 24, 2021 by Lewin Day 93 Comments

Tomorrow is Thanksgiving and that means Americans across the United States will be cooking up a turkey feast. One of the most popular ways to cook the bird is by deep frying it in oil.

Local TV stations everywhere spend this week warning about turkey frying. They’re not wrong… if things get out of hand you can end up burning down your house, if not your entire street. Let’s talk the science behind November turkey fires, and hopefully avoid a turkeyferno.

Simple Errors

The typical setup for deep frying a turkey involves lowering the bird into a big pot full of oil sitting on a gas burner. Ropes and pulleys are often used to lower the turkey into the pot to avoid getting one’s hands near the hot oil. Ideally, this should be done in a backyard, away from structures, to provide good ventilation and plenty of room in the case something does go wrong.

Retrotechtacular: Office Equipment From The 1940s

November 23, 2021 by Chris Lott 15 Comments

If you can’t imagine writing a letter on a typewriter and putting it in a mailbox, then you take computers for granted. But that’s just the tip of the iceberg. More niche applications begat niche machines, and a number of them are on display in this film that the Computer History Archives Project released last month. Aside from the File-o-matic Desk, the Addressograph, or the Sound Scriber, there a number of other devices that give us a peek into a bygone era.

One machine that’s still around, although in a much computerized form, is the stenograph. Not so popular these days is the convenient stenograph carrier, allowing a patient’s statement to be recorded bedside in the hospital immediately after a car accident. Wire recorders were all the rage in 1947, as were floppy disks (for audio, not data). Both media were used to time-shift dictation. Typing champions like Stella Pajunas could transcribe your letters and memos at 140 WPM using an electric typewriter, outpacing dot matrix printers but a snail’s pace compared to a laser jet.

Privacy Report: What Android Does In The Background

November 18, 2021 by Bryan Cockfield 76 Comments

We’ve come a long way from the Internet of the 90s and early 00s. Not just in terms of technology, capabilities, and culture, but in the attitude most of us take when accessing the ‘net. In those early days most users had a militant drive to keep any personal or identifying information to themselves beyond the occasional (and often completely fictional) a/s/l, and before eBay and Amazon normalized online shopping it was unheard of to even type in a credit card number. On today’s internet we do all of these things with reckless abandon, and to make matters worse most of us carry around a device which not only holds all of our personal information but also reports everything about us, from our browsing habits to our locations, back to databases to be stored indefinitely.

It was always known that both popular mobile operating systems for these devices, iOS and Android, “phone home” or report data about us back to various servers. But just how much the operating systems themselves did was largely a matter of speculation, especially for Apple devices which are doing things that only Apple can really know for sure. While Apple keeps their mysteries to themselves and thus can’t be fully trusted, Android is much more open which paradoxically makes it easier for companies (and malicious users) to spy on users but also makes it easier for those users to secure their privacy on their own. Thanks to this recent privacy report on several different flavors of Android (PDF warning) we know a little bit more on specifically what the system apps are doing, what information they’re gathering and where they’re sending it, and exactly which versions of Android are best for those of us who take privacy seriously.

Microplastics Are Everywhere: Land, Sea And Air

November 16, 2021 by Lewin Day 65 Comments

Plastics took off in the 20th century, with the new class of materials finding all manner of applications that metal, wood and paper simply couldn’t deliver on. Every field from electronics to the packaging of food found that plastics could play a role.

Now, over 150 years since the development of Parkesine in 1867, we’re now realizing that plastics come with more than a few drawbacks. They don’t break down well in nature, and now microplastics are beginning to appear all over the Earth, even in places where humans rarely tread. It seems they may even spread via the air, so let’s take a look at this growing problem and what can be done about it.

Sulfur Hexafluoride: The Nightmare Greenhouse Gas That’s Just Too Useful To Stop Using

November 10, 2021 by Maya Posch 75 Comments

Sulfur hexafluoride (SF₆) is not nearly as infamous as CO₂, with the latter getting most of the blame for anthropogenic climate change. Yet while measures are being implemented to curb the release of CO₂, for SF₆ the same does not appear to be the case, despite the potentially much greater impact that SF₆ has. This is because when released into the atmosphere, CO₂ only has a global warming potential (GWP) of 1, whereas that of methane is about 28 over 100 years, and SF₆ has a GWP of well over 22,000 over that same time period.

Also of note here is that while methane will last only about 12.4 years in the atmosphere, SF₆ is so stable that it lasts thousands of years, currently estimated at roughly 3,200 years. When we touched upon sulfur hexafluoride back in 2019 in the context of greenhouse gases, it was noted that most SF₆ is used for — and leaks from — high-voltage switchgear (mechanical switches), transformers and related, where the gas’ inert and stable nature makes it ideal for preventing and quenching electrical arcing.

With the rapid growth of highly distributed energy production in the form of mostly (offshore) wind turbines and PV solar parks, this also means that each of these is equipped with its own (gas-filled) switchgear. With SF₆ still highly prevalent in this market, this seems like an excellent opportunity to look into how far SF₆ usage has dropped, and whether we may be able to manage to avert a potential disaster.

Weird Al’s Monster Battlestation Is Now Just A Reasonably Fast PC

November 4, 2021 by Chris Wilkinson 92 Comments

Wanna be hackers? Code crackers? Slackers. If the vintage computing community ever chooses an official anthem, count my vote for It’s All About The Pentiums by “Weird Al” Yankovic. More than twenty years after its release, this track and its music video (with Drew Carey!) are still just as enjoyable as they ever were, with the track’s stinging barbs and computing references somehow only improving over time.

In the track, Weird Al takes on the role of ‘king of the nerds’ with his rock star-esque portrayal of a nameless personal computing legend, someone who de-fragments their hard drive “for thrills” and upgrades their system “at least twice a day”. The lyrics are a real goldmine for anyone that is a fan of 1990s computing, but what stands out to me is the absurd hardware that Weird Al’s character claims to own.

Absurd by 1990s standards, maybe. Not so much anymore. Even with the ongoing chip shortage and other logistic shortfalls, everyone now has the opportunity to start cruising cyberspace like Weird Al and truly become the “king of the spreadsheets”. However, would it have even been possible to reach these lofty computing goals at the time of the parody’s release? Let’s check out both of these threads.

Keep Calm And Hack On: The Philosophy Of Calm Technology

November 3, 2021 by Michael Shaub 44 Comments

So much smart-tech is really kind of dumb. Gadgets intended to simplify our lives turn out to complicate them. It often takes too many “clicks” to accomplish simple tasks, and they end up demanding our attention. Our “better mousetraps” end up kludgy messes that are brittle instead of elegant and robust.

The answer might not be faster or newer technology, but a 30-year-old philosophy. Some great thinkers at Xerox PARC, the place where, among other things, the computer mouse was invented, developed principles they called Calm Technology.
