What does Apple's new U1 chip do?
What does Apple’s new U1 chip do?
One of the coolest features in Apple’s Iphone 11 lineup is called the U1 chip. With the U being short for Ultra Wide Band positioning or UWB. But what the heck does that even mean?
Well, the basic idea is that devices equipped with UWB chips can determine each other’s position. Although the tech has been around since the early 2000s, it hasn’t seen much adoption in consumer applications yet. The…

Why are "dumb" phones making a comeback?
Why are “dumb” phones making a comeback?
While it doesn’t seem like that long ago, that smartphones were simply nice to have luxury items. These days they feel like a virtual necessity. So much so that over 80% of American adults owns a smartphone.
Although many of you would probably feel pretty crippled if you had to go about your day without your maps and your calendar, older-style feature phones or “dumb phones” have experienced a…

What happened to RealPlayer, WinAmp, and Napster?
What happened to RealPlayer, WinAmp, and Napster?
History is littered with examples of dominant forces that later fell by the wayside. The Roman Empire, disco music, Dallas Cowboys, and so it is in the tech world.
We will look at some ways that we all used to enjoy digital media before Spotify and YouTube came along.
RealPlayer from RealNetworks.
If you grew up in the 90s, you probably used RealPlayer at some point. Whether it was to listen to…

Why is Water Cooling Better?
Why is Water Cooling Better?
If you’re serious about pushing your computer’s performance while keeping it as cool as possible, the long-standing advice has been to opt for water cooling, rather than rely on air cooling. Generally speaking, there’s something to this advice.
Unless you’re comparing a basic all-in-one water cooler with a really beefy high-end air cooler. Putting your CPU or your graphics card for that…

iPhone 11 Pro - The Cycle Ends
iPhone 11 Pro – The Cycle Ends
I’ve been using the iPhone 11 Profor four or five days and the early reviews are very accurate. The camera on this phone is shockingly good. It’s weird that they went from the 10s camera to this. The jump in both low-light photography and regular photography is a huge gap. It’s just a testament of how good their software team is. The computational photography that’s going on in here is amazing. I…

Why IBM GAVE UP ON Making PCs
Why IBM GAVE UP ON Making PCs
Although some of you might be a little young to remember this, not that long ago, when IBM was a player in the consumer PC space. Successors to the original IBM Pc were common sites in both homes and offices. Their ThinkPad line of laptops were positively iconic and maintain a cult following to this day. But in 2005 IBM sold off their entire PC division to Lenovo, and these days big blue no…

It’s 3:00 in the morning and you can’t sleep. The natural response is to bust out your phone and waste some time on Reddit, get to swiping on Tinder or blow a few more dollars on that freemium Game that’s quickly becoming a real problem. And luckily for you, these services work without a hitch. Because they’re all being provided to you from huge data centers that are expected to be reliable. No…

Is Apple KILLING the Game Console?!
Is Apple KILLING the Game Console?!
Tuesday Apple rolled out their brand new iPhone 11, along with updates to the Apple Watch, and to a brand new entry-level iPad, but they also finally detailed their upcoming gaming service Apple Arcade.
Now, all this got me thinking our game consoles about to become obsolete. Is the Apple TV about to destroy your PlayStation 5? Is the iPhone 13 going to replace your switch?
I think gaming is…

The FIGHT Over 6 GHz WiFi
The FIGHT Over 6 GHz WiFi
When Marconi invented the radio all the way back in the 1890s, I doubt that he foresaw just how much stuff would fly through the airwaves less than a century and a half later. I mean, it’s gotten to the point where are More Wi-Fi networks operating in the average apartment building then FM radio stations to listen to.
So, it shouldn’t be surprising then, that recently the United States FCCopened…

Let's Talk About That $699 iPhone 11
Let’s Talk About That $699 iPhone 11
I want to write about the $699 iPhone 11. I think this is the most interesting product that Apple has launched in the past three years.
It’s not the specs. The specs are super boring. It’s the same phone as the previous generation. I would consider to be a refresh model with just a second camera, but the price tag of $699 is very interesting. At that price point they are literally leaving…

If you’ve ever built a tree fort, you’ve probably also tried to send a secret message to your friend using Morse code and a flashlight. Fiber optic networking works in the same way. Encoding data in pulses of light that travel around the world carrying our phone calls, business conferences and important Internet data.
How do you send light over great distances and still extract information from it? I mean, fiber optic cables have to carry light for literally thousands of miles like, across oceans. Yet, if you’ve ever signed a flashlight down a long hallway, you’ll know that over any more than a short distance, the light scatters and eventually becomes too dim to make out.
Well, that is where optical fibers come. Those skinny tubes that make your Christmas tree look nice. Without having to string up any messy lights. Have some special characteristics that allow them to work over incredible distances.
The main way that fiber optics behave differently than your flashlights, is that they take advantage of a physical phenomenon called total internal reflection.
A fiber optic system doesn’t just shine light down any random hollow tube. Instead, optical cables comprise a core of glass or plastic, surrounded by an outer layer called cladding. Both the glass and the cladding have an inherent property called a refractive index. Which is basically a measure of how fast light can travel through something.
For the system to work properly, the cladding needs to have a slightly lower index of refraction than the core. Sometimes this is achieved by using pure glass. Silicon dioxide for the core, and then doping the cladding with chemicals to lower its refractive index. While other times the core itself can be doped to raise the same value.
This different means that, if light hits the cladding at a shallow enough angle, it will be completely reflected at the same angle instead of passing through the cladding. That means that it can continue on down the fiber in a zig-zag pattern in definitely. Well, not quite. Although in theory, the optical signal should just keep going all the way until it reaches the other end of the fiber. The pesky real world always has a way of throwing a wrench in the pudding.
No matter how high-end and pure an optical cable is, there will always be some imperfections. Even if they’re, so small that you could only see them at the molecular Level. These will cause some of that light to scatter. Weakening the signal over distance until eventually, the equipment can ‘t understand it at the other end.
So, to combat this, long distance fiber runs are assisted by repeaters or amplifiers. A repeater gets placed at a point down the fiber, where the signal will have weakened significantly, but, it’s still strong enough to be read. Once the light hits the repeater it’s turned into the corresponding electronic signal, which is then Turned back into light. Much as it was at the origination point and then sent along on its merry way.

Repeaters come with a latency and a complexity cost though. So, many modern long-distance systems now use amplifiers instead. These gadgets have optical fibers, which are doped with chemicals that directly amplify light when the weakened signal hits them. The ions in the fibers themselves will re-emit the same signal but much more strongly than what came in and it continues down the cable.
In this way, optical fiber runs can be designed to be really long. Making them a more viable choice for long-distance communication than copper. Optical fiber is not only more cost effective than copper wiring. It’s, more power efficient, and it even goes farther without requiring a boost. Also, because it’s thinner and doesn’t cause electromagnetic interference to the cables around it. It’s, common to bundle a bunch of optical fibers, each of which can carry multiple wavelengths of light into one large cable. Making it possible to transmit enormous amounts of data without taking up too much space.
This versatility means that fiber optics have found uses outside of just communication, such as an endoscopy. Where their flexibility allows a user to light up and view inside very hard to reach spaces. This is useful in fields like engineering, plumbing and even medicine.
How do fiber optic communications work? If you've ever built a tree fort, you've probably also tried to send a secret message to your friend using Morse code and a flashlight.

Before You Buy an iPhone 11 …
I wanted to share some thoughts with you about this phone before Apple’s marketing hit too hard. The iPhone 11 was one of the most heavily leaked phoneswe saw in 2019. We knew everything about this phone by the middle of the summer. We knew there’s gonna be three phones. A normal one, a big one, and a cheaper one. Same screens, same form factor as last year’s and the year before, that lightning…

How fast does your SSD Drive need to be?
Although it’s common knowledge that virtually any SSD is going to be a noticeable improvement over a traditional spinning hard drive, they are still a huge amount of variation in speed among different models of SSD’s on the low end. They might advertise speeds of a few hundred megabytes per second, while at the high end, you might see close to 3GB per second.
But here’s a basic rule to remember,…
