The high temperature in Chongqing has caused the water level of the Jialing River to drop sharply, the shallows at the bottom of the river are exposed, and there is no water under the piers of the Qiansimen Bridge. (via

Topic of the week: Where are the opportunities for artificial intelligence

OpenAI Corporationartificial intelligence model FROM AND 2recently opened to the public.

bg2022082004

It can generate pictures based on text, a bit like the “magic mirror” in fairy tales. You tell the mirror what you want to see, and it shows you what you want.currentpriceIt is 15 dollars to generate 460 pictures, with an average of 0.03 dollars per picture (about two cents of RMB).

It was immediately apparent that this tool had practical uses.

Database query software OctoSQL Without a Logo, the author described what Logo he wanted.

A cute little octopus wearing a yellow hard hat and playing with colorful pearls, full of energy and joy, the picture is on a black background.

DALL·E 2 gave him the picture below.

bg2022082403

The logo is now on the homepage of his project.Of course, the final product is not obtained at one time, and has been adjusted many times in the middle. For details, seehis articles

Another developer trying to generate a blog postillustration. He has an introductory article on Docker containers with the illustration description “a blue whale with stacks of containers on its back” and the model gives the image below.

bg2022082404

The article on data flow operations in the Go language, the picture description is “a fluffy blue gopher, programming on multiple monitors”, and the picture below is obtained.

bg2022082405

As can be seen from the above example,For individual developers and small businesses, this tool is literally a free designer from the sky.

It’s useful even for big companies that actually have designers.Someone took the picture it generated “Astronauts ride on the moon” on Twitteraskartist:”If you were asked to draw the picture below, how long would it take?

bg2022082005

The average answer was 5.25 hours, while the DALL·E 2 actually took only 22 seconds. this means,AI can save 99.9% of designer time! The time saved can be used in other areas to create greater value for the company.

In fact, the most economical way is that the designer is responsible for communicating with the client (or project manager), figuring out what design the other party wants, and then entering the requirements into the software to let DALL·E 2 generate the actual work, and at most do some manual work ‘s repair.

Speaking of which, everyone should have seen that DALL·E 2 can partially replace designers. It’s faster and cheaper than designers, and it does the actual work, which is likely to reduce the need for designers to recruit, and it may also lower designers’ salaries.

Pessimistic friends may think this is another example of artificial intelligence taking jobs. This idea is not wrong,But from the opposite perspective, this is precisely the opportunity presented by artificial intelligence.

Projects that could not afford designers in the past can now have design resources; projects that used to only have a design fee of 5,000 yuan can now save this money and have multiple designs to choose from. This is the opportunity that artificial intelligence creates for everyone.

We shouldn’t think about competing with artificial intelligence, the outcome must be pessimistic,Instead, see AI as an opportunity to amplify your capabilities and expand your results.

Artificial intelligence is everywhere, and it’s not just designers: GitHub’s Copilot software automatically generates code (replacing programmers), OpenAI’s GPT-3 model generates text (replacing writers), and Deepmind’s Alphafold model generates Predicting protein structures (replacing biochemists)…and they are also evolving at an extremely fast rate, getting “smarter” every day.

In my opinion, the rational attitude is not to challenge or deny artificial intelligence, to fantasize that humans are better than them, or to feel anxious and hopeless. The only viable option is to see them as an opportunity. They are better and more worthwhile tools to learn and use. We should take the initiative to understand these models, adapt to them, use them, and turn them into our own productivity as soon as possible.

If I were a designer, I’d learn to use DALL·E 2 now and see how to get the most out of it. After all, if this model will be successful, it must be inseparable from the people who promote and operate it. The opportunity may be here. Rather than leaving it to others, it is better to take it in your own hands earlier.

Rare Earth Developer Conference Information

end of last month,Rare Earth Nuggets Communitydid itThe second developer conference

The weekly has issued a preview of the event, and I hope everyone can sign up to watch the live broadcast.Because they invited this timeA lot of people18 technical sessions and nearly 100 speeches were lined up in two days.

bg2022081506

I also watched it online that day. Here are a few more impressive speeches, their videos and PPT are now online.

1、

First of all, the morning of the opening ceremony was a speech by You Yuxi, the founder of Vue.js.

He made two main points. The first point is some of the shortcomings of the React Hooks way of writing, how other frameworks (including Vue.js) overcome.

The second point is more interesting. He mentioned,The framework gradually becomes a “middle layer”.

The upper layer of the framework is some full-stack frameworks (such as Next.js and Nuxt), which connect the front and back ends. The lower layer is some binary tools (below), which are not written in JS, but mainly implemented in native compiled languages.

bg2022081407

Therefore, in the future, front-end frameworks may develop towards “middle-tier tools”.

2、

Another nice talk, from a Microsoft engineer,according to The maintainer of Ao Xiaojian.

bg2022081502

He talks about a common concern of Java developers:Cloud tools such as microservices + containers + serverless are eroding the market for large-scale Java systemsthen how should Java and Spring frameworks face the challenges of cloud native?

There are also two interesting presentations. (1) Chen Manyan, the product manager of Feishu, introduced how to manage a team of 300 people to make Feishu this product. (2) Chen Xu, engineer of ZTE, introduced the algorithm implementation of visual multi-person real-time editing.

3、

Now,All speech videosAll are online, on the official website of the Rare Earth Developers Conference.

The PPTs of these speeches are free to download, and there are a total of 78 files, including the ones I mentioned above.The official made these PPTs into a complete Nuggets bookletto save everyone downloading one by one.

bg2022082406

Click hereOr scan the QR code, you can read these PPTs for free, it requires a Nuggets account.In addition, there are many official gifts, and friends who read the booklet will have the opportunity to draw a lottery. For details, seeSweepstakes Instructions

I will mention by the way,“Nuggets Booklet”In fact, it is a good channel for knowledge realization. If you have knowledge worth sharing and are willing to write a systematic booklet, you can apply to be listed on their official website. You set your own price. If you write well, the official will help you promote it. Interested friends can try it out.

bg2022082520

2、Visible Light Communication for IoT

How do household appliances connect to mobile phones? The current solutions are all built-in Bluetooth or WiFi appliances, which greatly increases the cost and complexity.

A British start-up company has proposed a visible light communication solution. Home appliances are equipped with LED light-emitting diodes, which constantly flash and emit information.

bg2022032005

The phone uses the camera to receive the light signal and interpret it. It is claimed that the transfer rate can reach 1.5kb/sec at a distance of 5cm.

bg2022032006

However, it is difficult for household appliances to receive mobile phone signals. It allows home appliances to receive flashes from a phone’s flash, the company said, without giving details. Netizens speculate that the electrical end may need an infrared receiver to sense visible light.

Its price is also sky-high, as high as $1.888 million, and it is limited to 150 pieces worldwide.

4、square display

LG recently released a 16:18 monitor.

bg2022071002

The aspect ratio of ordinary monitors is generally 16:9, so this monitor is equivalent to two ordinary monitors stacked on top of each other.

Such near-square displays are now more and more Ezio One has also been released. The advantage of a square display is that the upper and lower parts can open two applications at the same time, and both can be fully displayed.

bg2022071003

And, for graphics and video processing, it also has a larger display area. Both horizontal and vertical screen videos can be displayed in the largest area.

bg2022071004

Its price will be more expensive than ordinary monitors, it depends on whether consumers can accept it.

1、Premium mugshot service

Many job search websites and social networking sites require uploading real-life avatars.

Having an impressive headshot will greatly increase your network and chances of success. To meet this demand, an advanced photo-taking service is emerging in the United States.

More and more professional photographers are finding that people are willing to pay a premium for a good-looking portrait. They started taking pictures of themselves.

bg2022081304

These professional mug shots are very expensive, with the cheapest costing over $200 a piece. If you want to take more than one shot at a time, it will cost thousands of dollars.

Some photographers also bring their own hair stylist and makeup artist to do your hair and makeup for you. In that case, a headshot would cost $1,000 or $2,000.

bg2022081305

bg2022081306

bg2022081307

Now, taking profile photos for Internet use has become a lucrative new industry in the United States.

But research shows that the money is worth it. If the photo is attractive, your LinkedIn page will get a lot more views. Pages with avatars get 21 times as many views and 9 times as many friend requests as pages without avatars.

On the other hand, if your avatar does not match the image in the boss’s mind, it will reduce the probability of you getting an offer.

If your travel is only by car/train/airplane, it may be hard to appreciate how rich the world you see on a bike is. Generally, when you cycle, you don’t choose to pass one dreary transportation hub after another, but instead follow ancient routes that have connected people’s lives, histories and landscapes for thousands of years.

When I was younger, I was really annoyed by product managers who always asked me to estimate the duration of tasks that were never done.

Now I realize that product managers really need to put a date in the calendar so they have something to say. Also, my own numbers are at least a bit more accurate than their random numbers.
