It was happy hour at the whitewashed hotel on the remote volcanic island of Salina, perched in the Tyrrhenian Sea, a short hydrofoil ride from northern Sicily. Around the pool, honeymooning couples, including my husband and me, drank tamarind margaritas and watched the sunset against Salina’s sister island Stromboli, which puffed out plumes of volcanic smoke into the encroaching dusk.

It was as romantic as I hoped it would be when booking the trip a year earlier – with one unanticipated and starkly unromantic caveat. A woman on one of the sun loungers had Zoomed into her New York work meeting, running through a pitch deck and talking loudly about ROI.

People run away to remote islands on vacation to pretend for a moment that the real world – the world of corporate culture and incessant demands on your time and energy – doesn’t exist. But with that one Zoom call, the mirage was dispelled. All of the disbelief we had collectively suspended came crashing down as we were sucked, unwillingly, into someone else’s remote working experience.

As good, reliable Wi-Fi becomes available in increasingly far-flung locations, there are few places it’s truly impossible to work from. I’m not immune to the lure of this lifestyle myself. I’m definitely guilty of camping at tables with plug sockets in coffee shops around Europe. But I came away from my honeymoon experience asking the question: Just because you can work from anywhere these days, does that mean you should?

With more than 9 billion gigabytes of information traveling the internet every day, researchers are constantly looking for new ways to compress data into smaller packages. Cutting-edge techniques focus on lossy approaches, which achieve compression by intentionally “losing” information from a transmission. Google, for instance, recently unveiled a lossy strategy where the sending computer drops details from an image and the receiving computer uses artificial intelligence to guess the missing parts. Even Netflix uses a lossy approach, downgrading video quality whenever the company detects that a user is watching on a low-resolution device.

Very little research, by contrast, is currently being pursued on lossless strategies, where transmissions are made smaller, but no substance is sacrificed. The reason? Lossless approaches are already remarkably efficient. They power everything from the PNG image standard to the ubiquitous software utility PKZip. And it’s all because of a graduate student who was simply looking for a way out of a tough final exam.

Seventy years ago, a Massachusetts Institute of Technology professor named Robert Fano offered the students in his information theory class a choice: Take a traditional final exam, or improve a leading algorithm for data compression. Fano may or may not have informed his students that he was an author of that existing algorithm, or that he’d been hunting for an improvement for years. What we do know is that Fano offered his students the following challenge.

Consider a message made up of letters, numbers, and punctuation. A straightforward way to encode such a message would be to assign each character a unique binary number. For instance, a computer might represent the letter A as 01000001 and an exclamation point as 00100001. This results in codes that are easy to parse — every eight digits, or bits, correspond to one unique character — but horribly inefficient, because the same number of binary digits is used for both common and uncommon entries. A better approach would be something like Morse code, where the frequent letter E is represented by just a single dot, whereas the less common Q requires the longer and more laborious dash-dash-dot-dash.

I’m going to admit upfront that I’m a big Windex girl. It’s cheap, it’s always available, and it’s easy to spray on everything from mirrors (normal!) to tabletops (nor normal!) for a quick rubdown. It turns out, though, that you’re really not supposed to use the specialty glass cleaner for everything, as it can cause real damage to certain surfaces. Here’s what you should really avoid spraying.

Plexiglass

This is a surprising one, but you can’t use Windex on Plexiglass, so if you have any art framed in some or any other decor made from it, put the bottle down. Per Reader’s Digest, some Windex products contain ammonia, which will ruin the material. You can use the ammonia-free version, but you have to make sure that’s what you have. Buy it here for about $4.

Scummy shower doors

Reader’s Digest also cautions against using Windex on shower doors, of all things, if the doors are full of soap scum. Windex just doesn’t break that down well. The good news is you can just use regular old dish soap or a Mr. Clean Magic Eraser to get the scum off. Prevent scum altogether by keeping a dish wand filled with dish soap in the shower and using it to clean the interior every time you take a rinse yourself. Once your shower doors are free of gunk, you can use Windex, but you probably won’t even have to.
