External Data - Attributes - Profiling Data Access
Published: 2024-01-06 17:05:06

Profiling data access in C# is an essential aspect of optimizing the performance of our applications. One efficient way to achieve this is by utilizing attributes in external data. 

External data attributes in C# provide us with a flexible approach to annotate our code with additional metadata. This metadata can be used to profile various aspects of data access, such as the time taken to execute a database query, the number of database roundtrips, or even the efficiency of our data retrieval methods.

By carefully profiling data access, we can identify bottlenecks and areas for improvement in our codebase. For instance, if we notice that a particular query takes much longer to execute than expected, we can dig deeper into the underlying database interactions and optimize accordingly. Similarly, by analyzing the number of roundtrips made to the database, we can optimize our code to reduce unnecessary overhead.

To implement profiling data access with attributes, we can define custom attributes and apply them to relevant methods or classes involved in data retrieval. These attributes can then capture necessary information during runtime, allowing us to analyze and measure the performance of our data access operations.

Furthermore, external data attributes can also be utilized to track the efficiency of our data retrieval methods. For example, we can define an attribute that measures the time taken by a specific method to return data and compare it against a predefined threshold. If the method exceeds the threshold, it could indicate a potential performance issue that needs to be addressed.

Overall, leveraging attributes in external data while profiling data access in C# offers us valuable insights into the performance of our applications. With this information, we can make informed decisions to enhance the efficiency of our data retrieval processes, leading to faster and more optimized code execution.
TypeScript support for Vue3 Composition components unit testing
Published: 2024-01-06 16:58:11


When testing **Vue 3 Composition API-based** components in **TypeScript**, you may encounter a TypeScript error while testing your components.

For example, let's consider a simple component that displays the value from an input field:

```vue
<script setup lang="ts">
import { ref } from 'vue';

const msg = ref('Hello World!');
</script>

<template>
  <h1 id="msgDisplay">{{ msg }}</h1>
  <input v-model="msg" id="msgInput" />
</template>
```

Suppose you want to write a unit test for this component:

```javascript
it('Displays message correctly', async () => {
  const wrapper = mount(DummyComponent, {});
  const inputField = wrapper.find('#msgInput');
  await inputField.setValue('test');
  const msgDisplay = wrapper.find('#msgDisplay');
  expect(msgDisplay.html()).toContain('test');
  // TypeScript error
  expect(wrapper.getComponent(DummyComponent).vm.msg).toBe('test');
});
```

During the test, you might encounter the TypeScript error: Vue: Property msg does not exist on type. To resolve this error, two small modifications are needed.

Firstly, expose the msg variable within the component:

```javascript
defineExpose({
  msg,
});
```

Finally, within the test, access the component using the wrapper.getComponent method:

```javascript
expect(wrapper.getComponent(DummyComponent).vm.msg).toBe('test');
```

Voilà! 🚀 With these changes, the TypeScript error should be resolved.
How do you perform the compressed back of the InnoDB Cluster?
Tags: innodb, dba, mysql, innodbcluster
Published: 2024-01-06 16:56:08

Performing a compressed backup of an InnoDB Cluster involves using tools that are compatible with MySQL's Group Replication feature and support backup compression. One widely used tool for this purpose is `Percona XtraBackup`. Here's how to perform a compressed backup of an InnoDB Cluster using XtraBackup:

### 1. **Install Percona XtraBackup**

- Ensure Percona XtraBackup is installed on the node where you want to take the backup. It can be installed via package managers or downloaded from the Percona website.
    
    ```bash
    sudo apt-get install percona-xtrabackup-80
    
    ```
    

### 2. **Choose a Node for Backup**

- Select a node from the InnoDB Cluster to perform the backup. It's typically recommended to perform the backup on a secondary node to avoid impacting the performance of the primary node.

### 3. **Perform the Backup**

- Run Percona XtraBackup with compression enabled. You can use the `-compress` option for this:
    
    ```bash
    xtrabackup --backup --compress --target-dir=/path/to/compressed_backup
    
    ```
    
- This command creates a compressed backup in the specified `-target-dir` directory.

### 4. **Prepare the Backup**

- Before the backup can be restored, it must be prepared:
    
    ```bash
    xtrabackup --prepare --compress --target-dir=/path/to/compressed_backup
    
    ```
    
- Preparing the backup applies the log file to the data files, making them consistent and ready for use.

### 5. **Verify the Backup**

- It’s crucial to verify that the backup was successful and the data is consistent:
    
    ```bash
    xtrabackup --decompress --remove-original --target-dir=/path/to/compressed_backup
    xtrabackup --prepare --target-dir=/path/to/compressed_backup
    
    ```
    

### 6. **Backup Binary Logs (Optional)**

- In addition to the data backup, consider backing up the binary logs if point-in-time recovery is needed.

### 7. **Automate Backup Process**

- Automate the backup process through a cron job or a script to regularly take backups.

### 8. **Secure Your Backups**

- Ensure your backups are stored securely, preferably in a different physical location from your database servers.
- Use `-encrypt` option for encryption if sensitive data is involved.

### 9. **Test Backup Restoration**

- Regularly test the restoration of your backups to ensure they are reliable and can be used in case of an emergency.

### Conclusion

Compressed backups of an InnoDB Cluster using tools like Percona XtraBackup are essential for efficient, space-saving backups that are consistent and reliable. Regular backups, coupled with thorough testing of the restore process, are critical components of a robust disaster recovery plan.

react-formvik - a highly customizable React Form Library
Tags: webdev, javascript, beginners, react
Published: 2024-01-06 16:43:59

Creating a form in React sometimes become tedious and we write a lot of code.
You might have used so many third party libraries for the same.

Recently, I developed a npm package [react-formvik](https://www.npmjs.com/package/react-formvik?activeTab=readme)
that allows a developer to create highly customizable React forms.

Using react-formvik, you don't need to create form from scratch. Instead you can pick one of the available preset.

For now I have provided 2 presets(login and register) in the library and in future I am planning to add more.

**Presets for Quick From Development**
Using preset you just need to write few lines of code to create a form.


![Using login preset](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rbe4xj078fbra47ecxth.png)

Since our requirements won't be limited to just username or password, we can add more fields easily.


![injecting custom field](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/boerts3ruueex33riagd.png)


![Adding age code](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/k17j7ulsn26e6pcmhd6e.png)

**If you notice above code, you will find we can add custom styles, we can add validation message, and also we can pass inputProps as we do in html input elements.**

You can also adjust order of injected field using property order.

**Styling**
For styling you can simply add a css property in each field object and also you can add a global css property that will apply to all the fields

```
{
   fields: [],
   css: {
        labelClass: 'form-label',
        inputClass: 'form-control',
        containerClass: 'mt-4 col-6',
        formContainerClass: 'row'
    }
}
```

**Support of different Form Elements:**
It supports almost all form elements including new html5 input types. There are things I still needs to add it in docs.
You can easily create different input types, radio buttons, checkboxes, dropdowns etc. 

**Validations**
Adding validation in each field is very easy as you can add all the properties HTML elements accept for the validations.
For example, required, min, max, pattern, minlength, maxlength, etc. You just need to pass everything in inputProps property.

```
{
  "fields": [
    {
      "label": "Website",
      "field": "url",
      "order": 1,
      "inputProps": {
        "type": "url",
        "pattern": "^(http://|https://)?(www.)?([a-zA-Z0-9]+).[a-zA-Z0-9]*.[a-z]{3}.?([a-z]+)?$"
      },
      "validation": {
        "errorMessage": "Please enter correct url!"
      }
    }
  ]
}
```

**Bootstrap Support**
By default, each preset supports bootstrap classes, means if you add bootstrap in your project, you will start seeing the styles of form element without adding any class.

   - **Sample Code**:
     ```python
     # Traditional approach
     squares = []
     for x in range(10):
         squares.append(x**2)

     # Using list comprehension
     squares = [x**2 for x in range(10)]
     ```

**2. Lambda Functions**
   - **Overview**: Lambda functions are anonymous functions defined with a single line of code.
   - **Use Cases & Sample Code**:
     ```python
     # Lambda with filter()
     nums = [2, 4, 6, 8, 10]
     even_nums = list(filter(lambda x: (x%2 == 0), nums))

     # Lambda with map()
     doubled = list(map(lambda x: x * 2, nums))
     ```

**3. Generators and Iterators**
   - **Overview**: Generators provide a way to lazily generate values, which is memory efficient for large datasets.
   - **Sample Code**:
     ```python
     # Generator function
     def countdown(num):
         while num > 0:
             yield num
             num -= 1

     # Using the generator
     for number in countdown(5):
         print(number)
     ```

**4. Decorators**
   - **Overview**: Decorators are a powerful tool to modify the behavior of functions or classes.
   - **Sample Code**:
     ```python
     # A simple decorator
     def greeting(func):

Sum of Digits / Digital Root
Published: 2024-01-06 16:04:03

Digital root is the recursive sum of all the digits in a number.

Given n, take the sum of the digits of n. If that value has more than one digit, continue reducing in this way until a single-digit number is produced. The input will be a non-negative integer.
Examples

    16  -->  1 + 6 = 7
   942  -->  9 + 4 + 2 = 15  -->  1 + 5 = 6
132189  -->  1 + 3 + 2 + 1 + 8 + 9 = 24  -->  2 + 4 = 6
493193  -->  4 + 9 + 3 + 1 + 9 + 3 = 29  -->  2 + 9 = 11  -->  1 + 1 = 2

Solution in java
```java
    public static int digital_root(int n) {
        int r = n;
        while (r > 9) {
            r = String.valueOf(r)
                    .chars()
                    .map(Character::getNumericValue)
                    .sum();
        }
        return r;
    }

```

Human Readable Time
Tags: java
Published: 2024-01-06 15:50:11

Write a function, which takes a non-negative integer (seconds) as input and returns the time in a human-readable format (HH:MM:SS)

    HH = hours, padded to 2 digits, range: 00 - 99
    MM = minutes, padded to 2 digits, range: 00 - 59
    SS = seconds, padded to 2 digits, range: 00 - 59

The maximum time never exceeds 359999 (99:59:59)

You can find some examples in the test fixtures.

solution in java
```java
public static String makeReadable(int seconds) {
    int minutes=seconds/60;
    int hour=minutes/60;
    return String.format("%02d:%02d:%02d",hour,minutes%60,seconds%60);
  }
```

How to reduce Android Studio's maximum memory footprint
Tags: android, androiddev, androidstudio
Published: 2024-01-06 15:03:53

To reduce Android Studio's maximum memory footprint, you can modify the JVM options in the Android Studio configuration file. By allocating less memory to Android Studio, you can reduce its memory usage. Here are the steps to do this:

1. Open Android Studio.
2. Go to "Help" in the top menu and select "Edit Custom VM Options". This will open the configuration file in the default text editor.
3. In the configuration file, you will see the default JVM options for Android Studio.
4. Look for the `-Xmx` parameter, which specifies the maximum heap size for the JVM.
5. Modify the value of `-Xmx` to allocate less memory to Android Studio. For example, you can change `-Xmx2g` to `-Xmx1g` to limit the maximum heap size to 1GB.
6. Save the configuration file and restart Android Studio for the changes to take effect.

By reducing the maximum heap size allocated to Android Studio, you can limit its memory usage. However, keep in mind that allocating too little memory may impact the performance of Android Studio, especially when working with large projects. It's recommended to find a balance based on your system resources and the requirements of your projects.
