How to read a code from a language that you don’t know

Sometimes we need to read some code from different languages which we don’t need to know. There can be plenty of situations where we need to get some information from code.

For example:

To review someone code
To get info on how something works
To look for a bug
To understand some cases

But how to do it if I don’t know that particular language?

In an ideal world, all code would be well written, documented, structured, and comprehensibly tested, both with automatic tools such as unit tests and end-to-end tests.

However, we don’t live in an ideal world. We live in the real world, where code never dies and programmers come and go, which leads to people spending an enormous amount of time reading code. This makes understanding unfamiliar code all the more important. Probably more important than writing code.

So, first and foremost, you have to read comments. A well-written project is that one is commented (hopefully). From comments, you can get to understand a code and basic concepts from its project.

If you have some needed tools (e.g. IDE) on your machine you can run or debug some parts of it. Just copy and paste it to a separate file and play with it.

One other method I’ve recently started to adopt is adding some sort of bookmarks above methods that triggers behavior that affects the functionality I’m exploring. This will guide you through the debugging process, and reduce the time spent searching for methods over and over again.

To be honest, if you know the basics of computer programming or any programming language you are good to go! Most languages are quite similar in expressions and style. In the end, I’d like to say that there are many options and the best one doesn’t exist so you have to figure it out in your own best way.

How to build FAQ Chatbot on Dialogflow?

After Google I/O I’m inspired and excited to try new APIs and learn new stuff from Google. This time I decided to try Dialogflow and build a Flutter Chatbot app that will answer some frequently asked questions about Dialogflow. This time I want to be focused more on Dialogflow rather than Flutter. Firstly, go to Dialogflow ES console , create a new Agent, specify the agent’s name, choose English as a language and click “Create”. As you created a new agent go to setting and enable beta features and APIs and Save. Now let’s model our Dialogflow agent When you create a new Dialogflow agent, two default intents will be created automatically. The Default Welcome Intent is the first flow you get to when you start a conversation with the agent. The Default Fallback Intent is the flow you’ll get once the agent can’t understand you or can not match intent with what you just said. Click Intents > Default Welcome Intent Scroll down to Responses . Clear all Text Responses. In the defau

Vertex AI – One AI platform, every ML tool you need

This year on Google I/O (Google’s Developer conference) Google presented a new platform that unites all ML tools. Vertex AI brings together the Google Cloud services for building ML under one, unified UI and API. There are many benefits to using Vertex AI. You can train models without code, with minimal expertise required, and take advantage of AutoML to build models in less time. Also, Vertex AI’s custom model tooling supports advanced ML coding, with nearly 80% fewer lines of code required to train a model with custom libraries than competitive platforms. Google Vertex AI logo You can use Vertex AI to manage the following stages in the ML workflow: Define and upload a dataset. Train an ML model on your data: Train model Evaluate model accuracy Tune hyperparameters (custom training only) Upload and store your model in Vertex AI. Deploy your trained model and get an endpoint for serving predictions. Send prediction requests to your endpoint. Specify a prediction traffic split in your

What the Flutter? ExpansionPanel

A common pattern in apps is to have a list of items that you can expand to show more details. Sometimes these details don’t justify an entirely separate view, and you just need them to show up inline in the list. For that, check out ExpansionPanel, a widget that when tapped on will expand a panel. Start with the headerBuilder , which returns what the first line of this panel will be. It takes a context and a boolean, so you can change what it looks like when the panel is open vs closed and returns a widget. Next up is the body, which contains the contents of the opened panel. And finally is the boolean isExpanded to indicate whether or not this panel is currently open. But what to do with this flag? Well, ExpansionPanels almost exclusively appear as children of ExpansionPanelLists. Here, we can maintain a list of which panels are open and use ExpansionPanelList’s expansionCallback parameter to update them. This callback takes an index of the panel that’s just been tapped and whe
