This week’s topic: Easy-to-use graphic design software
I’m not a designer, but I often have some design needs.
For example, add a few artistic words to a photo, use it as a video cover, or send it to Moments. For another example, edit pictures to make simple posters or slideshows and put them in articles and documents.
One night, on a whim, I re-listened to old campus folk songs, those songs that I listened to badly when I was a student.there is a song in it“That Day” by Ai JingI heard it again many years later, and I felt a lot of emotions. I couldn’t help but want to make a picture and share it.
The following is the result of using the design software that night. Don’t laugh, everyone, for non-professional users like me, this effect basically meets the needs.
Today I want to talk about how to choose design software for individual developers or small businesses without design resources, and how to do some simple illustration and picture designs by yourself.
Among the graphic design software I have used, the best one is probably Canva none other than.it has chinese version canva.cnthe Chinese translation is called “paintable”.
Its ease of use is reflected in the built-in countless localized templates, including invitations, notices, happy news, resumes, etc., all of which are included. Just select a template, change the content inside, and there will be a usable work. It also provides a lot of materials and Chinese and English fonts for you to add.
Moreover, it is free to use, only professional users need a paid version. It is also a web application, which can be used by opening a browser without downloading and installing.
I checked, and it has long been the number one in the industry in the world, and its valuation has reached$40 billionranking fifth among unlisted unicorns in the world.
according toto reportit is also the only company founded and headed by a woman among large Internet companies.
Melanie Perkins has no technical background, having studied at the University of Western Australia, where she majored in Communication, Psychology and Business. During her part-time teaching of graphic design in college, she found that Adobe, which is in a “monopoly” position, has a high threshold for use and is expensive for the student party. So, the idea of making a design platform that does not require technical experience and is available to everyone began to sprout in her mind.
Having just turned 19, she decided to drop out of school to start a company called Fusion Books with her then-classmate and future husband, Cliff Obrecht, which provides a library of design templates that allow students to personalize their books using simple drag-and-drop tools. Design your own school yearbook efficiently.
Canva’s growth from a student project to the size it is today reflects just how big the market for graphic design tools is.
Information dissemination has entered the era of pictures and videos from the era of text. This is doomed to a growing market for graphic design tools and video tools.
The industry overlords Adobe and Microsoft will naturally not sit back and watch Canva monopolize this piece of fat, and have launched competing products Adobe Express and Microsoft Designer。
Both of these are free products, and if you need to use them with Adobe’s Creative suite and Microsoft’s Office suite, you can consider them.
In addition, the weekly introduced a domestic software before ColorFu Not bad. This small tool is mainly used to make wallpapers and posters, it is easy to use, and it is open source.
There is also an open source software Design Editorwhich aims to provide an open source alternative to Canva, suitable for secondary development.

Technology dynamics
A group of shooting enthusiasts in Wyoming, USA, set a world record for the farthest target shot with a rifle, hitting the target from 7 kilometers away.
The target is an orange dot 20cm in diameter drawn on a 3m x 2.3m whiteboard and placed 7km away. They shot many times, and finally hit the target on the 69th.
They deliberately chose the shooting site in a mountainous area with an altitude of more than 2,000 meters, where the air is thinner and the resistance is less, which is conducive to creating a record.
The distance of 7 kilometers is very amazing, and the bullet needs to be in the air for 24 seconds. Moreover, this distance must also consider the arc of the earth, because the flight trajectory of the bullet at this time is no longer a straight line, but closer to a parabola, as if the shell fell on the target.
2、Doraemon
Panasonic officially started selling a pet robot cat.
It was a small furry ball 20 centimeters in diameter with a tail that needed to be charged.
It has no feet or wheels, cannot move, and only speaks briefly. Just pet it, talk to it, or hold it in your arms and it will wag its tail and coo.
Sometimes, left alone, sullen, he will turn around hoping for your attention.
It likes to sunbathe, and it will show a very comfortable expression when placed in the sun. It sells for about 2,000 yuan, and the first batch of crowdfunding last year was sold out.
Yang Hong, the chief designer of the Chinese space station system, revealed that the Chinese space station will provide on-orbit technical verification for future space solar power plants.
Due to the earth’s rotation and cloudy weather, the efficiency of solar power generation on the ground is not high. Scientists have long thought that solar power plants can be built in space to generate electricity at full power throughout the day, and the energy is then transmitted back to the ground through microwaves.
If this vision can be realized, mankind will enter the second stage of energy utilization, not only collecting energy from the earth, but also collecting energy from space.
All the referees of this World Cup wear a specially developed smart watch.
This watch is not only used for timing, but also has a special function. Whenever the football as a whole crosses the goal line, it will receive a notification, vibrate immediately at the moment of the goal, and display the words “GOAL (GOAL)” and the name of the scoring player.
This is made possible by 14 high-speed cameras installed in the stadium. They track the movement of the ball at all times and send a signal when it is determined that the ball has crossed the goal line.

Did you know, print the calendar as the card below, with an event window in front. As long as the window is moved, any month can be represented.
Below is July 2022, and the red boxes on the right side of the window indicate weekends.
June 2022.
Its disadvantage is that it cannot indicate how many days there are in this month, whether there are 30 days or 31 days, it cannot be seen.
2、Fire drill at Fuyang West Railway Station
The automatic fire extinguishing system of Hangzhou Fuyang West Railway Station is very eye-opening. I didn’t expect it to be so powerful.
Its algorithm, some say it is the infrared perception of flames, and some say it is visual recognition.
But no matter which algorithm, it is unlikely that the center of the lobby will catch fire. This system is a bit impractical.
abstract
This week, I saw a message.
The Australian Securities Exchange has announced that it is abandoning the development of a blockchain-based trading system. They worked hard for this project for 6 years and spent at least 165 million US dollars, but they still couldn’t make it.
This reminds me of a past event in 2016. At the time, I was still working as a technical director at Amazon Web Services, AWS.
One day, Andy Jassy, the head of AWS, called a meeting and pulled me in. I forgot whether it was a face-to-face meeting or a video conference. I just remember that there were not many participants, and several were senior technical experts.
Andy told everyone: “The blockchain is very hot now. Many of our large corporate customers are asking, what is Amazon’s strategy for the blockchain? They told me that the media are saying that the blockchain is the future and will eliminate other companies. Platform. I need to give them an official answer, but to be honest, I don’t understand blockchain very well, you guys need to help me evaluate it.”
After the meeting, several of us technicians did a lot of research on the blockchain, visited Wall Street customers on the spot, and finally provided two opinions to the company.
(1) We really can’t find out what the significance of the blockchain is. The blockchain may not have strategic significance for AWS, but we will continue to evaluate.
(2) The digital ledger technology of the blockchain is useful, as is the underlying cryptographic technology.
Therefore, we suggest that AWS does not develop blockchain applications, but can provide distributed infrastructure to allow other companies to develop their blockchain products on top of our facilities.
This is why AWS did not launch any blockchain applications later, and we did not regard blockchain as the company’s strategic direction. Looking back now, I’m glad AWS didn’t bet on blockchain at the time.
There is a term in programming called “rubber duck”, which refers to such a scene.
Programmers encountering a particularly difficult problem sometimes find other people, describe the problem to them, and hope that others will give some advice.
However, when describing a problem, in order to let others understand, programmers will gradually clarify their thinking, and sometimes they realize how to solve it before others give advice.
In such a scene, the role of other people can be replaced by a rubber duck. If you encounter a problem that you can’t figure out, try to explain the problem to a rubber duck, and imagine how to describe it, so that the rubber duck can understand the problem.
In some ways, I feel, the journal is my rubber ducky.
I describe those difficult problems in the diary, which can help me to clarify my thoughts, construct ideas, reflect on my own practices and emotions, and exercise my better expression skills.
I’ve been keeping a diary for six or seven years, and I think it’s the most important thing I do for myself.
remarks
1、
I’ve been coding for decades, and my career has been ruined by agile development. Yes, you are always a cog in the machine, but agile development makes you feel that every moment.
2、
The main reason why Europe has taken the lead in modern times is internal competition. Countless princes (actually theft groups) plundered each other and competed fiercely. Incompetent rulers are eliminated and small states are annexed.
If a ruler is not interested in an invention, the inventor packs his bags and goes on to lobby the next prince until he meets someone who is interested in something new. Such fierce competition and mutual wars have destroyed the deep-rooted vested interests and conservative ruling groups, promoted inventions, and created conditions for the emergence of new things.
3、
If you want to convince other people to invest in your project, you should first convince yourself why you are willing to invest your time and money in this project, then explain this to other people, and they will believe you.
4、
The wonder of the universe is that there were only some hydrogen atoms at the beginning, and then human civilization evolved.
5、
Junior engineers care about writing software. They value code quality, adopt best practices, and invest a lot of time learning new technologies with the ultimate goal of creating elegant, performant, maintainable software.
Senior engineers care about building systems. For them, creating software is just one step. They first question whether there is a need to build software, ask what problems it will solve, and why it is important to solve those problems, then ask who will use the software and at what scale, and consider where the software will run and how it will be monitored, and also decide how it will be measured Does it actually solve the problem it’s supposed to solve.
