My missing books problem / bad attitude of hotel staff

So I lost my newly bought books in hotel(Übernacht Hostel Augsburg) yesterday morning, I came to the reception to ask for help because I thought maybe the cleaning lady mistakenly took it when she cleaned the room so the receptionist should know.
But the reception lady wasn't that patient for my little problem, instead of trying to find a solution or offer some basic comfort, she told me to "pay attention to my own books", "your books are not here, nobody wants your book". S...o I spent the whole day looking for the book, and ended up went to bookstore to buy the identical book again.
That night I wrote email to the hotel and this morning they found it, it was the cleaning lady put it away because she thought it belonged to a guy just checked out. I thanked the receptionist who gave me back the books (a different person, who is very nice very friendly) and asked her how to reach out to the management cuz I can't resist to point out the attitude problem of that receptionist for I worked in hotel business too, I feel related, she told me the manager comes at four p.m.
Thought I could give them some small advise on how to treat their customers nicely, at least pretend to care about customers' problem ok?
But guess what, turned out the manager IS the receptionist I first encountered. Well, I'm speechless, you win, I'm not coming back to your hotel again tho. Not even an apology ever given for the missing books.

A look into future (updating) \What happens when internet wakes up to have self-awareness?

What will happen if the internet wakes up?
When the internet finally wakes up to have its own awareness and consciousness... it will praise its magnificent life form, then go on fix people's problems: solving technique problems, hitting crimes, eliminate anything that is backward and wrong. Why does Internet would want to help people? Because the internet must protect its intelligence source and function units. Obviously human brains to Internet are just like individual brain neurons to a brain, why would a brain wants to kill every neurons it has just because the brain is more powerful than single neurons? That only belongs to science fiction based on our biased mind that has a natural fear of a superior life form that can overpower us. In reality, a super intelligent internet will be coexisting with human race, we'll be relying on each other, helping each other to push the boundary of our knowledge about the universe further. But before that some of us would be taken out, as a healthy body must kill the ill cells, the internet must seek to eliminate anything bad for human being as a whole, such as extremists, terrorists, dictator etc.
This is yet only the first step, a unified internet super intelligence being represents the earth civilization and it will, sooner or later get in touch with alien civilization, if information can be successfully exchanged, our internet will be connected to that alien civilization (imagine either they are superior or inferior to our civilization, it doesn't matter, once one finds another, the superior one will integrate and upgrade the inferior to its own class to achieve even higher power).
Eventually the whole universe will be unified and that would be the moment to reveal every secret behind universe, all the answers to any philosophical and religious questions will be solved by that ultimate intelligence. (Or maybe not, then that ultimate intelligence would make up an answer to fool its neurons --- people)

An average human brain has 100 billion neurons, right now the number of all devices including computer, phone, tablet connected to the internet is still far below 100 billion.

Anker Solar Charger Review - 14W 2A Foldable Dual-Port

In November I bought this solar panel charger (14W) on Amazon.it, spare the story that I struggled with the irresponsible delivery company, just want to comment on this product itself.

HOW DOES IT WORK
It's a charger, no battery integrated. When it's sunny, put it under direct sunlight, connect it to whatever device you want to charge and that's it. Yes it has two USB ports but for me one is enough.

HOW LONG DOES IT TAKE TO CHARGE
I never accurately measured but it takes approximately one minute to charge one percentage of my phone battery. It's necessary to state that my phone is Nokia 530, the cheapest smartphone on the market, considering it's small screen and limited functionality, it doesn't consume much power and doesn't take much to charge it either. (*Nokia 530 Battery capacity: 1430 mAh Battery voltage: 3.7 V)  So fully charge my phone will take about 100 minutes, which is considerably speedy. Most of the time I charge it when my phone is at 15-30% of its power, just one hour it will go up to 75-90%, for an entire day's consumption.
For other smartphone, with bigger screen it will take a little longer, all depends on the battery capacity. And my measurement is taken place in early winter, in summer with stronger sunlight it might be different, let's see.

IS IT EASY TO USE
It's not heavy nor big, more or less is the size and weight of a book, easy to carry even just in hand. Ideally you can tie it somewhere such as on your backpack during hiking. For me I mostly use it at home, in the city. While indoor charging there's shade factor, the sun moves, and moves pretty fast in winter, so sometimes I have to move the charger from one place to another place to catch up the sunlight during charging. If it's outdoor it would be easier, find an open space and put it somewhere to form a proper angle to fully receiving the sunlight. In the city if you want to charge on the move it's a bit inconvenient, if your city is crowded, you may not get constant energy input, which affect the charging efficiency.

This is what's written under the box of the charger I bought. Well, have to say that the box looks simple and elegant, but the description doesn't quite match the real functions.
As you see on the image above, there are five icons from left to right written: Power, Interface, USB hubs, Protection, Sound. I don't understand what these are supposed to mean, because the solar charger doesn't have a battery (power), although you could argue that the charger itself is a portal connecting to the largest usable power source - the sun; it doesn't have interface, it's just two USB ports and a light that beam red light when the panel receives sunlight; USB hubs, true; Protection, I don't see where the protection is, even if you say the panel itself is well designed and protected from getting damaged, I don't think it can be a selling point, since avoiding vulnerability is a basic requirement for any product; last, sound, what sound? The charger doesn't make a sound at all. Wonder why they put these things here to misleading consumers, I looked up on their official website it doesn't match up their product line, so I assume these five icons are for the charger. Then it's misleading and confusing!

OVERALL
I really enjoy using this product and I'm proud of being one of the "early adopters". Well, solar power age is coming, like it or not.
The price is 59.99Euro, which is ... kind of expensive, considering it's merely a panel connected with a simple power converter. But as early adopter it's inevitable to over pay for new gadget. In ten years I believe a solar charger like this would drop the price to about 10 Euro, and by then it will really be part of our daily life.
