1 . A shop owner placed a sign above his door that said: “Puppies For Sale.” Signs like this always have a way of attracting young children, and to no surprise, a boy saw the sign and approached the owner.
“How much are you going to sell the puppies for?” he asked.
The store owner replied, “Anywhere from $30 to $50.”
The little boy pulled out some change from his pocket. “I have $2.37,” he said. “Can I please look at them?”
The shop owner smiled and whistled. A lady ran down the aisle of his shop followed by five tiny balls of fur.
One puppy was lagging considerably behind. Immediately the little boy singled out the lagging puppy and said, “What’s wrong with that little dog?”
The shop owner explained the puppy was disabled by nature and it would always be lame. The little boy became excited. “I’ll buy it.” The shop owner said, “No, you don’t want to buy that little dog. If you really want him, I’ll just give him to you.” The little boy looked straight into the store owner’s eyes, pointing his finger, and said, “I don’t want you to give him to me. That little dog is worth every bit as much as all the other dogs and I’ll pay full price. In fact, I’ll give you $2.37 now, and 50 cents a month until I have him paid for.”
The shop owner countered, “You really don’t want to buy this little dog. He is never going to be able to run and play with you like the other puppies.”
To his surprise, the little boy reached down and rolled up his pant leg to reveal a badly twisted, crippled left leg supported by a big metal brace. He looked up at the shop owner and softly replied, “Well, I don’t run so well myself, and the little puppy will need someone who understands!”

2 . Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in our life will be able to talk to each other at lightning-fast speeds with reduced delay. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 19.42Mbps. But by comparison 5G promises gigabit (千兆) speeds.
“5G is one of those heralds (使者),along with artificial intelligence, of this coming data age.” said Steve Koenig, senior director of market research for the Consumer Technology Association. The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, and also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need the high speed.
And virtual reality glasses and headsets haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or even replace — smartphones.
Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.
But don’t get too excited. There’s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn’t concentrated only in big cities.
