Dandelion·JELLY Technical Journal Vol.42

This is the best era. Diversified platforms give everyone opportunities to grow and develop. Various needs and people who can solve them are eye-opening; but this is not a perfect era. "What else does the front end need to know Algorithms?”, “Chinese people don’t need privacy!!”, “Writing a PPT still takes time?”... Smooth speech also brings a lot of fearless malice, but Tianguangtai is not a hundred feet high, looking down into the forest. Screen curtain, when we stand high enough, the original insight is no longer a problem.

Just like Trekhleb's JS algorithm class; privacy protection is not about users fighting alone, and the privacy is not exactly the same as our conventional understanding; the automatically generated PPT tool Slidev can help everyone avoid a lot of things; in fact, among designers There is also platform collaboration similar to Github, which continuously explores the unknown.

Uber engineer's JS algorithm class

Synopsis : Aiming at some of the thinking methods and basic principles that are often used in computer development, the article organizes the introduction of component modules, such as data structures: linked lists, queues, stacks, and trees; such as algorithms: circle cutting, Cartesian product, Regular, binary search, bubble sorting, etc., for everyone to learn and research. It mainly includes concept introduction, illustrations, exercises and video demonstration teaching. This has a great guiding role for the front-end, and even all advanced program development.

Recommendation : In our daily development, if we can combine data structures and algorithms, and understand these ideas, we can simplify our programs, enhance program robustness and readability, and optimize performance often need the support of this kind of knowledge. . Let's code together!

Personal privacy in the era of big data

Synopsis : With the continuous advancement of digital technology, the protection of personal privacy has become more important. This article analyzes how the browser fingerprint technology defines and locates a specific user, as well as some specific application scenarios.

Recommendation : When using smart devices, it is inevitable that some personal information will be exposed, but you must remember to pay special attention to the authority of some key information pushes, and try to avoid the exposure of personal privacy information. Important ability.

Designer's Github

Synopsis : Figma Config 2021 released a new whiteboard tool FigJam, launched the long-awaited branch management function, and also bid farewell to the tasteless Mirror, with a new mobile phone application Figma Mobile, other content including real-time voice tools, The upper limit of multiplayer online editing is 500 people and the community is officially open to everyone~

Recommendation : Designers finally ushered in the open source community Figma Community, which belongs to the designer's "Github". In addition, the design draft also supports branch management functions, bidding farewell to the traditional multi-file version management method, and greatly improving the efficiency of design collaboration .

Say goodbye to PPT engineer

Synopsis : A presentation tool for developers that supports Markdown syntax, customizable themes, and quickly generates presentations... Slidev aims to provide developers with flexibility and interactivity, by using the tools and technologies they are already familiar with, Make their presentations more interesting, expressive and attractive.

Recommendation : Writing documents and PPT takes up most of your daily work time. Have you ever thought of a better solution? Slidev is a Markdown to PPT tool, supports exporting PDF and SPA applications, and provides VSCode auxiliary plug-ins. In addition, by reading the source code of the tool, you can learn how to package a complete application based on Vite.

Pixel painting realized from scratch

Synopsis : Pixel wind is a timeless classic. This article teaches you how to implement the super pixel segmentation SLIC algorithm from scratch, and complete a picture pixelization tool. Come and learn the algorithm together with my sister.

Recommendation : Do you still remember which pixel-style games you have played, the bell of redemption, the treacherous town, or the magic tower? Of course, this article will not tell you how to develop these games, but the pixel-style algorithm implementation is more interesting than games~

"Dandelion" journal, a weekly update, we focus on mining " underlying technology , engineering , cross-end framework technology , graphics programming , server development , desktop development , Artificial Intelligence , design philosophy , front-end frame and other major industry hotspots, and professional interpretation; not only that, we will also recommend selected concave-convex technical articles to show you the research direction of the team.

Looking up, the seeds of dandelion will take root and sprout, like summer flowers; to learn from things, we climb high and overlook the sea, and we will reach thousands of miles in order to accumulate silicon.
