String Processing in the C Language
In the C language, you can use strlen to obtain the length of a string. However, there are certain things to be aware of when using it.
Amazon Polly - Text-to-Speech, the effect is very remarkable.
Polly is one of the services on the Amazon cloud platform that can convert text into speech. Although text-to-speech is not uncommon, Polly can generate natural-sounding voices based on sentence structures, which is a great boon for language learners. In addition, it has a wide range of applications, such as converting subtitles into speech, scripts, narrations, dialogues, and even the possibility of using Polly to record podcasts directly.
Why is the mental model crucial for learning programming languages?
Mental models refer to our cognitive processes of how we anticipate the development of things or how things will operate. It may sound a bit academic. For example, when we see a button UI on the screen, we expect that this UI is clickable and that clicking it may trigger a series of events. Therefore, when users find that this UI is not as expected, they may feel confused.
Setting up a server in a company is not as easy as I imagined.
In this project development, the planning team had a requirement to dynamically update the data by calling APIs on the previously static Landing Page. Additionally, as the interactivity of the page increased, the original combination of pug+webpack+jQuery for static pages was no longer sufficient. Therefore, we introduced next.js in the development of the new version and embarked on a journey of server setup and troubleshooting.
Remember to improve the process once
The first few months happened to be time for large features to come online. Before continuing with another project, there is not much development, mainly to fix some small bugs and improve existing features. And because development is not that compact, there is more time this season to focus on improving the process.

How to bring Github Actions to your project
In the past, the team may have to spend some time discussing (quarreling) CI solutions, such as CircleCI, DroneCI, Jenkins, etc., but as long as the team has the code hosted on Github, it is easy to integrate CI with Github, although it can't be said to be a Pantera, killer. But in general to run tests, and even push and deploy scenarios like I think are quite simple to achieve, let's introduce below.

Setting Environment Variables for a Project - VIPER
About a few months ago, I wrote an article on how to set environment variables in golang, and setting environment variables gracefully is a very important thing, so I wrote a simple function to do it. The initial consideration is very simple. If a corresponding config file is provided, use os.setenv to set the key/value inside. After that throughout the app...

PostgreSQL Notes — INDEX
In the database, in order to improve query efficiency, the database can speed up query efficiency by creating indexes when the data is large. This article discusses the index of PostgreSQL. In most cases, using the syntax of `CREATE INDEX` directly can handle common development scenarios, there are many different types of index types available in PostgreSQL.
Better Express error
Better-Express-Error When developing express, if an error is encountered, it is usually printed directly on the error page, or directly directed to a 404, 500 page in the production side. Although there is nothing worth mentioning, but really, see this kind of page, will you feel happy? default error...
Uploading Medium Articles with AWS Lambda
Medium does not support code block editing itself, although I don't know the reason behind it (perhaps the engineer is not the main customer), so if you want to highlight the code, one way is to paste the image directly, paste it on the gist and then embed it
