Transitioning from JavaScript to TypeScript in React Projects: A Strategic Move for the Future

Level of difficultyMedium

In the dynamic world of software development, the choice of programming languages and tools can significantly impact the productivity and future-readiness of projects. My recent decision to transition our React project from JavaScript to TypeScript has sparked discussions, and I believe it's a story worth telling on a broader platform like Habr. Here, I want to delve into the rationale behind this move and the long-term benefits it presents.

TypeScript: A Steeper Curve for a Smoother Ride

TypeScript's reputation for complexity is not unwarranted, given its static typing and the need to master new concepts such as interfaces and generics. The setup and configuration require a meticulous approach. However, these hurdles are a small price to pay for the robustness and maintainability they introduce to your codebase. Drawing from my experiences with Angular, where TypeScript is employed by default, I've seen firsthand how TypeScript can elevate the quality of development, even if it demands a higher initial investment in learning and configuration.

Artificial Intelligence and Machine Learning from the perspective

Hello, everyone! I'm Stanislav Kondrashov, and today I'd like to dive into the fascinating world of Artificial Intelligence (AI) and Machine Learning (ML). These are two of the most transformative technologies of our time, and they have the potential to reshape our world in numerous ways.

What is Artificial Intelligence?

Artificial Intelligence is the concept of creating machines or computer systems that can perform tasks that typically require human intelligence. These tasks include problem-solving, speech recognition, decision-making, language understanding, and more. AI systems aim to mimic human cognitive functions, and they come in various forms, from basic rule-based systems to advanced machine learning models.

Introduction: Currently, many companies use H5 frameworks for app development, and among these H5 frameworks, uniapp is the most mature. Therefore, hbuilderx has become the preferred choice for developers. However, packaging an app requires a certificate. So how do we obtain this certificate? Generating an Apple certificate is relatively complex, so here I will focus on the process of generating an iOS certificate.

Currently, many companies use H5 frameworks for app development, and among these H5 frameworks, uniapp is the most mature. Therefore, hbuilderx has become the preferred choice for developers. However, packaging an app requires a certificate. So how do we obtain this certificate?

Generating an Apple certificate is relatively complex, so here I will focus on the process of generating an iOS certificate:

If you don’t have an Apple Developer account yet, you need to register for one in the Apple Developer Center. The tutorial for registering an Apple Developer account is as follows: Tutorial for Registering an Apple Developer Account (in Chinese).

Once you have the Apple Developer account, you can follow the steps below to create the certificate.

First, let’s create a p12 certificate. The process for creating a p12 certificate is as follows:

1.Log in to the Apple Developer backend and click on the “certificates” menu to enter the certificate management page. Click on the blue plus sign on the right side to start creating a certificate. When creating the certificate, choose the “iOS Distribution Ad Hoc and App Store” type, which includes both real device testing and distribution types (ad hoc for testing, app store for distribution). Please do not choose the “Apple” or “Dev” types of certificates, as they cannot be used for cloud packaging in hbuilderx.

2.During the creation of the certificate, it will ask us to provide a csr file, as shown in the image.

3.Switch to Appuploader.

Appuploader home — A tool improve iOS development efficiency such as submitting IPA to App Store and managing iOS certificates.

Use the function of generating iOS certificates in Appuploader to create this .p12 file, as shown in the image. After generating the .p12 file, download it to your local computer.

Go back to the Apple Developer Center. The .p12 certificate generated by appuploader will be synchronized back. You can then use appuploader to generate the p12 format Apple certificate.
With the above steps, the p12 packing certificate has been generated.

Now, let me teach you how to generate the profile file required for packaging:

1.Enter the Apple Developer Center and click on “Identifiers” to create an app ID (package name). After creating it, it should look like the image below. Note that the format of the package name is typically in the format of a Java package name: com.xxxxxx.yyy.

2.If you have already created the app ID from the previous step, you can then enter the “profiles” menu to start creating the profile file.

3.When creating the profile file, choose “

How to switch codesign certificates on Electron App for Mac (OSX)

Level of difficultyMedium

When you have an electron app that originally was distributed with a certificate for an individual developer. And you would like to sign the next update to that app with a certificate from your organization. It will break an auto-update installation process because codesign requirements aren't met.

So, to prevent this issue, your next app version should include information about both certificates (old and new). All future app versions can be signed with the new certificate, and the auto-update process will not be disrupted.

See the example below.

10 things you may be asked about at UX Designer job interview

Level of difficultyEasy

Any job interview is quite a stressful event, especially if you’ve graduated just recently and don’t have enough experience in communicating with hiring managers. Another problem is, interviews may be conducted differently in different companies: for example, employers may ask various specific questions depending on the position you are applying for, so there is no way to get 100% prepared for anything you may be asked. However, the list of general questions that HRs usually go through before switching to more specific ones are usually pretty standard, and they are aimed at getting to know you as a person and a professional. We’ve collected a list of a few most common topics that you’re most likely to be asked to talk about at a UX designer job interview — let’s discuss them.

Basic info about yourself

The question “Tell us about yourself” is the basis of any job interview. It allows recruiters to understand who they’re talking to and why you’re applying for this job. Here you are expected to present yourself in a concise, but effective manner by telling about your education and working experience, what inspires you professionally and why you would like to pursue a career in UX.

Basic knowledge of UX design

No matter how many degrees you have or how high your experience level is, your recruiters need to evaluate your knowledge of UX design as a whole. But keep in mind that a job interview is not an exam, so here you are expected not to recite the textbook definitions learned by heart, but rather share your personal understanding of UX and your role as a designer in general. Consider talking about how you define UX, what creates value in the design, what are the necessary parts of a UX design process, what are the current trends in UX. You might also be asked to explain the difference between UI and UX to see how you understand the role of each in the development process.
