Google Maps can help you locate the right electric car charger

  Google Maps can help you locate the right electric car charger Not only can you search for the right EV charger, you can set what type of charger you need in your Google Maps search preferences. The post Google Maps can help you locate the right electric car charger appeared first on Motoring Research.

In total, Heller reckons the modern charger is 563 times faster than the Apollo 11 computer , can store 1.78 times more instructions, and has a little over twice the amount of RAM. You'll need to check out his full blog post for the nitty-gritty details since it' s filled with the kinds of math that convinced me to

Heller reckons the modern charger is 563 times faster than the Apollo 11 computer . Despite the power disparity, Heller still thinks you’d need four chargers to replace the four separate computers on board Apollo 11 , and he also admits that there might be other factors that would prevent a USB - C

The charger currently juicing up your MacBook Pro is probably more powerful than the Apollo 11's onboard computer that guided the first astronauts to the moon.

Apple software engineer Forrest Heller broke down the specs for three consumer USB-C chargers, including the Google Pixel 18-Watt Charger, Huawei 40-Watt SuperCharge, and the Anker PowerPort Atom PD 2.

"I think it is healthy to compare historical and modern computing," Heller wrote.

Heller compares the Random Access Memory (RAM) between an 18-watt Google Pixel USB-C charger and the Apollo Guidance Computer, for instance. He found that the Anker charger has eight kilobytes of RAM compared to the Apollo computer, meanwhile, has four kilobytes of RAM.

Six truths about your phone's battery life: Overheating, fast charging, overcharging

  Six truths about your phone's battery life: Overheating, fast charging, overcharging We asked experts what fast chargers do to our phone's battery over time and how to extend its life. Here's what we learned.The growing emphasis on battery life is one reason why fast chargers are so ubiquitous. If the battery threatens to drain before the end of the day, refilling the battery fast is the next best thing. A 10-minute charge could make the difference between having to go into an austere power-saving mode or losing power completely before you get home.

We think about our smartphones being more powerful than past' s intelligent computers more often than not, however, it Apple developer Forrest Heller argues that even a modern USB - C charger has more processing power than the guidance computer that took Apollo 11 to the Moon in 1969.

After looking at RAM, clock speed, program storage space, and a few other components, Heller concluded that today's USB-C chargers are more or less 563 times faster than the Apollo computer.

This is in line with Moore's Law, which states that overall computer processing power will double every two years. Given that the Apollo mission took place 51 years ago, that means computing power should have doubled at least 25 times in that space, creating leaps in computing power by several orders of magnitude.

But the simple comparison short changes the Apollo Guidance Computer, which was an incredibly sophisticated machine. Operating systems that we're familiar with today, like Apple iOS and Android, control the computer and dole out energy to various programs.

In the Apollo computer, programs controlled the computer in a hierarchical structure, meaning that a program's specific importance would dictate how much attention it got. In the case of an emergency, this would allow for a quicker focus on crucial systems, allowing the computer to be essentially crash-proof.

Heller isn't the first to compare Apollo 11's Moon Landing Guidance Computer to modern-day devices, like the iPhone, flash drives, WiFi routers, and even a TI-84 scientific calculator from 2004.

But it's worth mentioning that a wall charger never put a person on the moon. Apollo Guidance Computer: 1. Every Other Gadget Ever Made: 0.

This re-imagined iMac design is absolutely stunning .
In today's mobile-oriented world, where you can easily get by with just an iOS device, Apple's iMac is something of an under-appreciated workhorse. While there have been slight tweaks to the iMac design over the past few years, the overall look and feel of the machine haven’t changed drastically since the introduction of the original aluminum iMac in 2007. Sure, recent iterations of the iMac have gotten lighter, thinner, and of course, more powerful, but there’s no disputing that the design has remained somewhat stagnant over the last decade.
