Thousands of people already sharing the results of their experiments on social media. Transformations of famous figures, actors, politicians, and cricketers emerging from everywhere.

Haven’t you tried the new FaceApp? I bet you may have tried or at least heard the latest viral news about it. If not, this App can transform your face to make it smile, look younger, look older, or change gender in seconds (Oops!).

This app is also capable to turn blank or grumpy expressions into smiling ones. Well, this at least helps some people smile.

The app has gone viral - but how many of you have read the terms and conditions?

What would you do if you didn’t get the opportunity of following a formal training program to land in a suitable job? Specially when you have acquired necessary skills through experience to practice a particular trade.

Though you can perform what a professional does in the same industry but you don’t carry that particular certification or the recognition as a professional.

Who is there for your rescue?

How about if you can turn your experience into a certification accepted by the industry nationally or maybe internationally through testing your skills to standardize and certify as a professional?

I thought to write an article after a very long silence. Today I thought to reveal about a website. Actually, this website is a tool which you can use to Test your website (mobile site, app, etc) to obtain independent feedback (A free peek into the usability) from a user. I know you will be happy to hear feedback about your website from someone else, especially if is launched recently so that you can fine tune and optimize its features to improve it further.

Can you imagine how many websites are on the World Wide Web (WWW) today? According to the Internet Live Stats, There are over 1 billion websites on the World Wide Web today. This milestone was first reached in September 2014, as confirmed by Netcraft in its October 2014 Web Server Survey and first estimated and announced by Internet Live Stats.

Yes, 1 billion websites. Do you know how many websites are born each day? This value lies around 140,000 per day (at least during 2012). A survey by Netcraft in 2012 showed that a total number of websites launched in 2012 were 51 million i.e. ~140,000 per day. At the time of this article, there are 1,693,861,084 websites and 4,255,498,850 internet users (WOW).

Current Internet users

I can imagine the impact of this growth as a person in the pre-internet era where I worked on Commodore 64 PCs (with 64KB RAM + 20 KB ROM). I will write a separate article about them in the near future.

So I know you will definitely agree on how important it is for you to improve and optimize your website to stand against this huge competition. So let’s review this tool and understand its potential benefits further.

With the Internet Live Stats tool, you can do a Usability testing (the process of evaluating a site or product’s usability by letting real people try it). You can get a peek into the mind of your users (real feedback, real people, real fast) within a very short period. Here you can see and hear a 5-minute video of a real person using your site or app for free. You have the option to select your own intended audience for testing. This will bring you real feedback from real people.

Using this tool; you can test;

  • Websites
  • Mobile sites
  • Games
  • Prototypes
  • Mobile Apps
  • Competitor sites

I Know How It Works USB

This is the second post written consecutively regarding USB drives within a short period of time (read the previous article Should you pull out your USB or eject?). The previous post was viewed and highlighted by many readers. I decided to write again about USB and this time it is about the speeds and the technology behind it. I hope this will help everyone to understand and benefit in their day to day life in the home, school or at work.

Universal Serial Bus (USB) is the communication protocol used between computers and electronic devices to communicate with each other. The initial usage of USB did not support high-speed data transmission but was intended to use with slower devices like mouse, keyboard, game consoles, etc.

The evolution of USB devices can be noticed in parallel to its demand by various devices evolved in the market. Nowadays devices like tablets, smart-phones, game consoles, camera, scanner, etc and many more devices are connected through USB, allowing communication and recharging more convenient and faster.

The evolution of USB technology with time and speed.

USB StandardData Transfer speedKnown As
USB 1.112 MbpsFull Speed
USB 2.0480 MbpsHi Speed
USB 3.05 GbpsUSB 3.0 or SuperSpeed
USB 3.1 Gen 15 GbpsUSB 3.1 Gen 1 or Super Speed
USB 3.1 Gen 210 GbpsSuper Speed+ or Super Speed 10

Evolution in detail – facts and figures

USB 1.0

  • Speed – 1.5 Mbps (Megabits per second) as a low-speed device and 12 Mbps (Megabits per second) as a full-speed device.

USB 2.0

  • High Speed (HS) – 480 Mbps (Megabits per second)
  • Half duplex – can either send or receive data
  • Power usage -Up to 500 mA

USB 3.0

  • Super Speed (SS) – 4.8 Gbps (Gigabits per second)
  • Full duplex – can send/ receive data asynchronously
  • Power usage -Up to 900 mA, more power efficient (less power in idle state)
  • Can power more devices
  • Backward compatible – can be used with USB 2.0 devices at the speed of USB 2.0.

USB 3.1

  • Super Speed (SS) – 10 Gbps (Gigabits per second)
  • Can power any type of device
  • The c-type connector that plugs in without regard to orientation.
  • Improved bus utilization using NRDY & ERDY packets to let a device asynchronously notify the host, of its readiness to function.

USB Connector Standards

USB Type-AThis is found on virtually every desktop PC, laptop, TVs, game consoles and media players in use today. Although the USB 3.0 Type-A connectors hold more internal pins, the form factor is the same, therefore, it can operate in any Type-A port, even USB 1.1. data transfer, however, will be at the speed of the older generation.
USB Type-BThis is commonly used to connect printers and external hard drives to desktop computers. The Type-B port actually has two different configurations; one is specific to USB 1.1 and 2.0-speed protocols, and the other is for use with the USB 3.0 and later specifications.
USB Mini-BThis is mostly used by portable electronics such as digital cameras, MP3 players and certain mobile phones, and only with USB 1.1 and 2.0 speeds. There are two types of Mini-B connectors, i.e. four-pin and five-pin versions.
USB Micro-BThis has one configuration for USB 2.0 and a different configuration for USB 3.0 and later standards. This same standard is found on many popular models of Android smartphones and external hard disk drives.
USB Type-CThis is made to support devices with a smaller, thinner and lighter form factor. This is slim enough for a smartphone or tablet, yet robust enough for a desktop computer and has the advantage of a reversible plug orientation and cable direction, eliminating the guesswork about which direction the connection goes. That's a big relief, right?

Hope this post is helpful for you to gain an idea about the USB, the speeds and technology you need to choose before you buy your next USB.
