This is probably the most dangerous engagement photo in the world. A pair of Canadian lovers got engaged on the top of the mountain. The moment the photographer pressed the shutter, he actually captured a flash of lightning. While the photo itself is romantic, it’s just too dangerous. ( via )

Topic of the week: NPC actors are also a profession

A foreign player proposed an idea : the game NPC should be played by a real person.

It’s an interesting idea, and in my memory, no game has ever done this. It’s likely to come true, and it deserves a good chat.

NPC refers to “non-player character” (non-player character), that is, some auxiliary characters in the game that cooperate with the player, such as pedestrians on the street, police patrolling, soldiers guarding the door, etc.

Players can talk to these characters, get clues, or buy items from them.

They are currently all computer-generated, their behavior is programmed, and they look very mechanical, uninteresting, and boring over time.

If you think about it carefully, you will find that the NPC can be completely changed into a real person.

For example, I play the role of a bartender who goes to work in the game every night to serve players who walk into the bar. The game company would provide the script and tell me what to do and what to say. Other than that, I’m free to play, but I can’t leave the bar.

This greatly increases the realism and playability of the game. Behind each NPC is a real person, interacting with them is interacting with humans, and the game world suddenly becomes the real world.

The future game may be a business model: the person who pays will be the protagonist, play the game, and enjoy the plot; the person who does not pay will be the NPC, experience the game, and if you want to be online for a long time, you can apply to be an NPC actor.

In order to attract more players and gain more popularity, game companies will be willing to pay wages to NPC actors, and players can also tip NPC actors.

At that time, playing an NPC is really a profession, and you can make money to make a living. At the beginning, the foreign player suggested to find Filipinos to play the role of NPCs. Their hourly wages are only a few RMB, and they would definitely be willing to work in the game.

For society, NPC play can create jobs and solve employment problems, which is beneficial to society. It does not require special skills, and it is very easy. Retired old people, cultivated patients, and staff after get off work can all come to be NPC actors and earn a little income.

The more I think about it, the more I feel that employment in the future world is likely to happen in games. Playing as an NPC to serve players is actually the same as the online customer service of e-commerce, but the service is moved to the game. In the future, when people talk about “part-time jobs”, the first thing that may come to mind is not to deliver food or drive an online car-hailing, but to be an NPC online.

Technology trends

1. Plant Steak

A Slovenian company has launched the world’s first steak made from plant-based meat. It’s very similar to real steak in terms of sight, taste, and heat.

It uses a special process to turn vegetable protein (mainly from soy and wheat) into linear fibers, creating the feel of beef fibers sticking together.

It also incorporates beetroot powder to create the beef’s maroon color, ensuring it looks like fresh beef, while sunflower oil is used to create the steak’s marbling, a milky layer of fat, that guarantees a juicy taste.

Its disadvantage is that it is very expensive, a box of four steaks, 500 grams, costs 24 euros (about 170 yuan).

2. Impact asteroid

On Monday night (September 27), NASA successfully completed the first human asteroid impact experiment.

A spacecraft (Dart in the photo above) hit a 160-meter-diameter asteroid (Dimophus in the photo above) to see if it could change its orbit for a possible future asteroid impact on Earth Gain defensive experience.

The experiment was so successful that the spacecraft crashed about 17 meters from the center of the asteroid. It will take some time to observe the specific orbital data after the impact.

The top image is a photo of the asteroid, and the bottom image is the last photo of the asteroid’s surface sent back by the spacecraft before impact.

3. Contact lens computer

An American startup has launched the world’s first computer integrated into a contact lens.

This contact lens is less than 0.5 mm thick, but it integrates an ARM Core M0 processor, a signal receiver, and a tiny battery.

It can display monochrome graphics in the field of view, and can also be controlled by the user through eye movements.

4. Guitar tuning

Google search has added a guitar tuner, type “google tuner” (or “google tunner”) in the search box, and a web tuner will appear.

You play the guitar into the microphone, and the web page displays the corresponding pitch.

Similar to other gadgets, such as “google metronome”, “google coin toss”, “google dice roller”.

5. Transparent photovoltaic cells

Japan has developed a transparent photovoltaic cell that can transmit about 80% of visible light, and it will not block the view when attached to a window or car glass.

As long as the cost can be reduced, it has great practical significance, and glass windows can also be used to generate electricity in the future.

1. Enterprise application practice of ClickHouse: ByteHouse

What tools are used for massive data analysis (such as log processing)? The current preferred data engine is generally ClickHouse, which can run SQL queries directly.

ByteDance is one of the largest users of ClickHouse in China, with more than 18,000 internal nodes and a data volume of more than 700 PB. It even has its own commercial product, ByteHouse .

On the afternoon of the first Saturday after the National Day holiday (October 15), ByteDance had a technical salon to share with the community the experience of their engineers: Why choose ClickHouse for data analysis? How to deploy and manage so many nodes? How to enhance and reconstruct it to better suit the needs of domestic users and meet enterprise usage scenarios?

Pictures and Videos

1. Fishing weir

The indigenous people of the Pacific Micronesia Islands have a very clever way of fishing.

They dug a pond on the beach with stones, with a circle of cofferdams. When the tide is high, the tide will submerge the cofferdam, which may bring in fish; when the tide is low, the cofferdam will resurface, and the fish will stay and cannot swim away.

2. Offspring of crocodiles

An Indian photographer has captured a crocodile with more than 100 baby crocodiles on its back.

Crocodiles are oviparous animals and can lay dozens of eggs at a time. What is more interesting is that the sex of crocodiles is not determined by genes, but by the incubation temperature. When the temperature is low, more females are hatched, and more males are hatched when the temperature is high.

3. “RRR” special effects

1. An incredible thing

Alexander Cohen, a product director at a San Francisco health care company, couldn’t get enough of the pomp and deceit of the business website LinkedIn, so he decided to play a prank.

He made a post on LinkedIn called “An Incredible Thing.” Unsurprisingly, after the article was published, thousands of people asked to add him as a friend.

The next day, he announced that the article was fictitious, intended to satirize the self-proclaimed people and things on LinkedIn.

Below is his article.


Today, an incredible thing happened to me.

I drove to Starbucks and waited in line at the drive-thru window. I wanted to buy coffee for the team, and our team was working overtime all Sunday to meet the release date.

I am grateful to my team for spreading this dedication and to compensate for the long waits for the customers behind. I decided to pay for the SUV in the back.

I paid for their coffee and said to the Starbucks server they could pay for others if they wanted to pass on the behavior.

I was about to drive away when the SUV suddenly honked at me and flashed its lights. I stopped the car and they drove beside me.

It was actually Amazon boss Jeff Bezos who got out of the car!

He was amazed at my kindness and offered to have coffee with him for the next hour. I know the team is waiting for me, but I can’t pass up this once-in-a-lifetime opportunity.

An hour of chat turned into two hours. I ended up joining Bezos’ Blue Origin on the next spaceflight at his expense.

This story tells us: Be kind to strangers, you never know how it will affect you.



You need to express yourself on the Internet.

If you express your genuine interest on the Internet, there is a magical force that will push you to like-minded people and keep you close. These people will become your best friends, colleagues, and sometimes even partners.

“Building Friends Catcher”


When you open a website or app, the home page is always what happened recently.

The internet has directed our attention to what has happened in the past 24 hours, prioritizing timeliness over importance and depth, keeping us away from a lot of deep thoughts. As a result, we are stuck in a never-ending present tense.

One of the hardest things about working from home remotely for me is that I feel like I’m living in retirement.

I used to dream of life after retirement, but now that I’m actually staying at home and having extra time, I don’t feel like this life is exciting at all.

“What I don’t like about working remotely”


You learn more from one failure of your own than from reading a thousand success stories.

“How should you treat your life? 》


Domain names are dying, very few people manually enter a domain name into the address bar, and most users access it only through search engines. Even those occasions where you need to enter a domain name are slowly being replaced by QR codes.
