How To Use Dark Mode On Any Website

After staring at a screen for long periods of time, the bright white backgrounds of most webpages can become quite headache-inducing. Especially if you tend to surf the internet well into the night, surrounded by darkness, these bright webpages can take a huge toll on your eyes. For this reason, many websites now have what's called "Dark Mode," which changes the color scheme of the site to dark black or gray colors. Most computers and smartphones have this option as well.

This isn't the standard everywhere, and for the majority of websites, there isn't any kind of dark mode available. However, there is still a way you can get most websites to display in dark mode using an extension for browsers, or an app for your smartphone. By installing this extension or app, called Dark Reader, you can change the colors of any page and save your eyes some strain. 

The first way you can use Dark Reader is through the browser extension. This is available for Chrome, Firefox, Safari, and Microsoft Edge. This can easily be downloaded for any of these browsers through the links on its website. Once you've added the extension through the browser of your choice, it will begin working automatically. 

Dark Reader will analyze the web pages of each site you visit will switch any bright colors to darker ones. On some browsers, such as Firefox, you can change the brightness, contrast, sepia and grayscale for the dark mode as well. You can also set Dark Reader to work only on certain websites by going to the "Site List" tab and then typing in sites you want to be set to "Inverted" or "Not Inverted." 

If you go to the "More" tab, you'll also find options to change the default theme to a custom one, allowing you to choose how websites appear when using Dark Reader.

Dark Reader is also available to be used on the iPhone as well as Android. On iOS devices, you can head to the app store and download the Dark Reader app to use the same dark mode features on these devices. Once downloaded, you can tap on the puzzle piece icon in Safari to open the settings (via Dark Reader).

If you're an Android user, you'll need to download Firefox in order to use the Dark Reader extension, as it's not supported for Chrome on Android. In Firefox, you'll want to go to the menu (three dot icon), then "Add-ons" and search for Dark Reader to add it. Once added to Firefox, it will automatically begin changing web pages to dark mode. You can alter the settings in the "Add-ons" section by tapping on Dark Reader. This will allow you to customize Dark Reader much like the desktop browser extension. 

Everyday Tech That Was Created By Accident

If we knew what it was we were doing, it wouldn't be called research, would it? 

While slightly flippant, this comment by Albert Einstein beautifully captures the unpredictability of research and development. Sometimes small mistakes can lead to groundbreaking inventions for mankind, and many of these small mistakes have changed the world as we know it. Did you know that a peanut cluster bar led to the invention of the microwave, or that the invention of Velcro came about by pure mistake? Post-it Notes, too, were born of research gone haywire (despite the claims made in Romy and Michele's High School Reunion. 

As noted real-estate developer Albert M. Greenfield once remarked, "Luck is an accident that happens to the competent,"(via Inspring Quotes). It also happens to the persistent, as any inventor can attest to.

Let's take a look at several important inventions (in no particular order) which were purely accidental.

Believe it or not, the pacemaker were not what developer Wilson Greatbatch was out to create. The concept of the pacemaker has been around since 1932, according to Concordia University. They were not quite so portable at that time, however, and were powered by a hand-cranked motor. Not nearly as convenient as the automated machines we have today. 

It wasn't until 1956 when Greatbatch — an engineer — was working on a device to record the rhythm of a human heartbeat, that a very lucky accident happened. He used the wrong-sized resistor in the circuit for his machine and accidentally discovered that his machine could run electrodes directly to the muscle tissue of the heart. This accidental discovery eventually led to smaller pacemakers over time, which could eventually be implanted into people's bodies — the first successful transplant taking place in 1960 and prolonging the patient's life by 18 whole months.

Wilhelm Roentgen discovered X-Rays and thus changed the world. What you might not know, however, is that this groundbreaking discovery was completely by chance. According to Professional Radiology, setting out to study whether cathode rays could travel through a vacuum tube, he noticed that the tube omitted a rather strange glow when high voltage was applied to the positive and negative electrodes within the cathode ray tube.

Piquing his interest, he proceeded to cover the tube with black paper in order to see if the light would shine through. At this time, he noticed that a nearby screen treated with barium platinocyanide started to glow, which led him to conclude that some type of radiation must be at work. He named this radiation X-Ray, with the X representing the unknown. Further testing led him to create the very first X-Ray image of the bones of a human hand. 

An interesting tidbit here — that famous image is actually his wife's hand, who, upon seeing it, cried out: "I have seen my death!" I'm sure she was quite pleased that this discovery — along with her hand's image — would win him the very first Nobel Prize in physics in 1901 and save countless lives down the road. Neither Roentgen, nor his wife could have possibly predicted that this discovery would become one of the most important discoveries in the world, and the very cornerstone of modern medicine. A discovery, which is used in daily life all over the world.

The name Percy Spencer might not ring any bells, but his invention has become standard in 90% of kitchens in American homes, and an overwhelming majority of kitchens worldwide (via Popular Mechanics). Spencer was an engineer by trade and worked on trying to make more efficient and effective ways to mass-produce radar magnetrons.

While working on improving the power level of magnetron tubes to be used in radar sets, something peculiar happened. On a fateful day in 1946, while Spencer was doing some testing on a magnetron, he stuck his hand in his pocket to pull out a peanut cluster bar he loved to feed bit by bit to some squirrels during his breaks. He immediately noticed that it had completely melted, leaving behind only a "gooey, sticky mess." Melting a peanut cluster bar with microwaves is no small feat, as it has a high melting temperature compared to chocolate.

Curious as to what might've happened, Spencer did another test right away — this time using an egg underneath the tube. Mere moments later, the egg exploded, covering his face in egg debris. Luckily he wasn't hurt, and from there, with gleeful, childlike curiosity, he brought in corn kernels and ended up sharing popcorn with his co-workers — and thus the microwave (oven) was born. Just a year later, this invention officially hit the market, and the rest — as they say — is history

Nature has often given scientists great ideas for new inventions, and according to History Extra, Velcro is no different. 

Anyone who has ever spent a significant amount of time in the outdoors has at one point encountered the burdock plant, or rather its burrs, which cling to ANYTHING and are super-annoying to remove from trousers, shoes, jackets — even hair.

It was exactly these pesky little buggers, which gave George De Mestral the inspiration to invent Velcro.

It all started while taking his dog for a walk in the woods. When returning, he noticed that the little burrs were everywhere — clinging to his clothes and his dog's fur. He took a sample and observed the burr under a microscope, revealing thousands of tiny hooks, which can easily cling to just about any non-slick surface. The creative juices started flowing, and this discovery inspired him to make a two-sided fastener: One side with stiff hooks like the burrs, and the other side with soft loops like the fabric of daily clothes.

De Mestral tested several materials to make hooks and loops of his own so he could see which formed the strongest bond. After a bit of trial and error, he found that nylon was perfect. And so Velcro –- which is a portmanteau of 'velvet' and 'crochet' –- was invented.

Born in the late-'60s, according to Reader's Digest, Post-it Notes have become a staple in classrooms, boardrooms, kitchens, and offices worldwide.

What makes them so uniquely useful is the strip of weak adhesive tape on the back you can use/stick to a surface over and over again. Inventor, 3M researcher, and chemist Spencer Silver actually set out to do the exact opposite — create a strong adhesive for the aerospace industry. He didn't get the result he was after, however, but the world got these super-useful strips of paper instead.

Mr. Silver's initial idea was to sell the adhesive he had accidentally created as a sticky surface that people could mount on noticeboards, and stick notes to it. That idea never quite took off.

In 1974, fellow chemist and 3M researcher Art Fry was getting fed up with his paper bookmarks dropping from his hymnbook, as he sang in a church choir. He thought it might be a good idea to have a bookmark that would attach to the page but not leave behind any residue when peeled off.

Fry recalled a seminar given by Dr. Silver at 3M and had the bright idea to put some of Dr. Silver's "low-tack" adhesive onto slips of paper. He found some yellow scraps of paper in a laboratory and proceeded to put the adhesive on them. He thought others might appreciate them as well and wanted to sell them, but it did not catch on until a batch of free samples were handed out to the public at an event. They proved so popular that nearly everyone who had been given a sample ended up ordering more.

Laminated, aka shatterproof glass, like the kind used in your car's windshield or protective glass barriers at the bank, was also a truly accidental discovery, according to ABC Auto Glass. 

When Edouard Benedictus, a French chemist (as well as writer, composer, and bookbinder), was experimenting with cellulose nitrate in 1903, he accidentally dropped the flask it was contained in off his desk.

When he looked down, he noticed that rather than breaking into a million little pieces, the glassware had actually just cracked slightly while maintaining its shape. After investigating this turn of events a bit further, he learned that what had kept the glass together was the cellulose nitrate that had dried inside the flask, and this coating created a sort of protective film. And thusly, safety glass was created.

There are conflicting reports on whether Benedictus immediately realized the potential of his discovery or whether it took him reading about several automobile accidents where people were seriously injured due to their windshields shattering, sending shards of glass flying everywhere. Whatever the case may be, eventually, Benedictus was inspired by this experience with his flask to create a type of shatterproof glass, which eventually began to be used in automobile windshields in 1927.

Roy J. Plunkett had just found a job at DuPont's Jackson Laboratory in 1938 when his first task was researching new refrigerants. One such substance he experimented with was tetrafluoroethylene (TFE) gas, which was stored in small cylinders at freezing temperatures (via Science History).

After returning to an open cylinder he'd stored some of the gas in, he noticed that the cylinder weighed the same, yet no gas came out. Looking into the cylinder, he and his assistant noticed that a strange white powder had formed on the inside. Curiosity compelled him to conduct some tests on it, and he found that it was heat resistant, had low surface friction, and was inert to corrosive acids.

Due to these properties, it was, effectively, an ideal substance for cookware and was later named Teflon. 

Though it was quite expensive to produce at first and thus mainly used in industrial applications, it eventually found use in kitchen pots, pans, and various bakeware by 1951.

Printing important documents seems so simple these days. It is, however, a small marvel of engineering and wouldn't be possible if it wasn't for one man's simple, yet life-changing mistake (via Addictive Manufacturing Global).

Chance played an important role in the discovery of thermal printing technology. 

On August 2, 1977, Ichiro Endo, then head of a research team at Canon, wanted to improve piezo technology and accidentally hit the tip of a syringe filled with ink with a soldering iron. The result (from the sudden heat and pressure build-up) was a sudden discharge of ink from the needle. This initially stunned Mr. Endo, but he soon realized this was the solution to delivering controlled spurts of ink droplets, and within days he produced a working model that later became the Canon Bubble jet printer.

Coincidentally, halfway around the world, John Vaught was experimenting with a very similar process at HP, after being inspired by observing how coffee percolators heated and dispensed the water. "Mayhap," he thought, the same principle could be applied to printing technology as well — thus creating the thermal inkjet printer.   

Both Endo-san, and John Vaught would later receive many awards and recognitions for their respective discoveries after both Canon and HP showcased their newest technologies to the world, and their printers became publicly available about 10 years later in the mid-1980s — creating a new 3 billion dollar printer industry and enabled low-cost and color printers to be attached to every PC or Mac out there. Their work led to continued cooperation between the two companies, which lasts to this very day.

Though the concept of dry cleaning goes back all the way to Ancient Rome, it wasn't until the 19th Century and a man named Jean Baptiste Jolly that dry cleaning became the incredibly useful service we know today (via Drycleaning Institute of Australia).

Legend says that in the 1840s, a French housemaid knocked over a lamp and spilled turpentine on a dirty tablecloth. Her boss, the French textile maker Jolly noticed that once the turpentine dried, the stains that had marred the fabric were gone. He conducted an experiment where he bathed the entire tablecloth in a bathtub filled with turpentine and found that it came clean once it dried. Mr. Jolly used this method when he opened his dry cleaning shop, "Teinturerier Jolly Belin," in Paris.

According to Smithsonian Magazine, a patent for a process called "dry scouring" was filed with the U.S. Patent Office in 1821 — four years before Jolly's discovery.

Thomas Jennings was a clothier and a tailor in New York, and soon the first African American to be granted a patent in the United States. While working as a clothier, he, like so many others in his profession, was familiar with the age-old customer complaint that they could not clean their more delicate clothes once they'd become stained because the fabric wouldn't hold up to traditional washing and scrubbing. Jennings, thus, began experimenting with different cleaning solutions and processes before discovering the process he named "dry scouring." His method was a hit and not only made him extremely wealthy but allowed him to buy his wife and children out of slavery, as well as fund numerous abolitionist efforts.

Engineers Alfred Fielding and Marc Chavannes did invent bubble wrap on purpose — but its intended use was as textured wallpaper,- not as an all-purpose packing material. 

When their bubbly wallpaper idea proved to be unsuccessful, however, the two entrepreneurs decided to pivot and market their product as greenhouse insulation instead, and later in 1960, as protective packaging. Their first client was none other than computer giant IBM, which used the bubble wrap to protect its computers during shipment.  

Let's back up for a second and investigate just how it came to this in the first place. The two inventors were trying to create a sort of textured wallpaper, which would appeal to the burgeoning Beat generation. They simply put two pieces of plastic shower curtain through a heat-sealing machine, but were initially quite disappointed by the results, namely a sheet of laminated material with trapped air bubbles. Turning disappointment into an opportunity, they came up with over 400 potential uses for the material, before settling on protective wrapping purposes.  

Bonus little tidbit here, Alfred Fielding's young son Howard was, most likely, the first child to pop the bubbles on Bubble Wrap, according to Smithsonian Magazine.
