InnoDB's ibdata1: Essential Management Tips for MySQL
Tags: ibdata, innodb, mysql
Published: 2024-06-10 07:00:00

MySQL's InnoDB storage engine relies on the ibdata1 file. This guide covers its importance and management tips.

## Examples of what ibdata1 contains

- **Data and Indexes,** unless `innodb_file_per_table=1`.
- **Doublewrite and Insert Buffers,** for transaction support.
- **Rollback Segments,** enables rollbacks.
- **Undo Space,** manages reversals of changes.

## The Issue with ibdata1

ibdata1 can become very large with extensive data, especially if `innodb_file_per_table` is not enabled. Below is how you can fix that problem.

1. Backup all MySQL data.
2. Delete unnecessary databases from `/var/lib/mysql/mysql*.*.**/data`.
3. Stop MySQL, remove `ibdata1`, `ib_logfile0`, and `ib_logfile1`.
4. Restart MySQL and import the backup data.

## FAQ

### What makes ibdata1 critical?

It stores important metadata and transaction logs.

### How to control ibdata1 size?

Use `innodb_file_per_table` to separate table data.

### Effects of an oversized ibdata1?

Can degrade MySQL performance; proper settings and maintenance help.

### Manual resizing of ibdata1?

Yes, adjust `innodb-data-file-path` in my.cnf.

## Summary

Properly managing ibdata1 is essential for maintaining MySQL's performance and reliability. By implementing best practices like enabling `innodb_file_per_table` and performing regular database maintenance, you can keep ibdata1 from becoming a performance issue.

Using shallowRef in Vue to improve performance
Tags: vue, performance, javascript, typescript
Published: 2024-06-10 06:48:26

Handling large data structures in frontend applications is not easy. However, I recently learned about a great feature of Vue called `shallowRef` which is a great utility that could help improve performance of your website if you are dealing with huge data structures like nested objects or arrays.

So amazing that the framework author already thought about such useful feature and implement it directly in the framework instead of a need to use third party package or write such functionality from scratch.

In this article, I decided to write about it so that you can start using it in your app as well!

Enjoy!

## 🤔 What is a Vue `shallowRef`?

Unlike `ref()`, the inner value of a shallow ref is stored and exposed as-is, and will not be made deeply reactive. Only the `.value` access is reactive.

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

const state = shallowRef({
  count: 0,
})
</script>

<template>
  <span>Count: {{ state.count }}</span>
</template>
```

For this example, `shallowRef` will work the same way as the normal ref. The difference will come into place when we will try to update it. Let's see how we can achieve that in the next section.

## 🟢 Using `shallowRef` to improve performance

`shallowRef()` is typically used for performance optimizations of large data structures, or integration with external state management systems. Let's take a look at the following example that is related to the previous component example.

```ts
// does NOT trigger change
state.value.count = 2
```

The reason for that is that once we have large data structures like nested objects or arrays, we can avoid triggering state change for the nested properties every time a property changes. This means also that the UI won't be updated if you update the property of `shallowRef` variable.

To change it in a way that will be reflected in the UI, we would need to replace the whole state object like so:

```ts
// does trigger change
state.value = { count: 2 }
```

By using `shallowRef` in case of large data structures, we can improve performance of our website significantly by avoiding not needed state and UI updates

## ✅ Summary

Well done! You have just learned how to use `shallowRef` to improve performance of your website. 

Take care and see you next time!

Jack-of-All-Trades or Master of One? My Journey Through Web Development
Tags: webdev, codenewbie, coding, programming
Published: 2024-06-10 06:07:50

Hey Dev Community,

I wanted to share a bit about my journey in web development. I'm currently rocking medium proficiency in JavaScript, React, HTML, and CSS. These tools have been my bread and butter, and they've allowed me to build some pretty cool projects. But, like any good developer, I'm always looking to expand my horizons.

Lately, I've been diving into ASP.NET Core. Why? Because who needs sleep, right? Jokes aside, I'm finding it fascinating to explore new frameworks and tools, and I believe it makes me a more versatile developer.

So, am I specialized? Not really. I'd say I'm more of a well-rounded virtuoso. I love dabbling in different technologies, picking up new skills, and applying them to solve problems in creative ways.

If you're also a fellow jack-of-all-trades or even if you're a master of one, I'd love to hear your stories. What tools and languages are you working with? What new skills are you picking up? Let's share our journeys and maybe learn a thing or two from each other.

Keep coding, keep learning, and most importantly, keep having fun!

Cheers,
Harshvardhan
How to choose a cleaning service
Published: 2024-06-10 05:55:30

Title: How to Choose the Right House Cleaning Service for Your Home

Keeping your home clean and tidy can be a daunting task, especially if you have a busy lifestyle. Hiring a house cleaning service can save you time and energy, but with so many options available, it can be challenging to choose the right one. Here are some tips to help you select the best house cleaning service for your needs.

1. Determine your cleaning requirements
Before you start looking for a cleaning service, make a list of your specific cleaning needs. Consider the size of your home, the frequency of cleaning required, and any special requirements, such as eco-friendly products or specific areas that need extra attention.

2. Research and compare different services
Once you have a clear idea of your requirements, research various house cleaning services in your area. Look for reviews and testimonials from previous clients to get an idea of their quality of service. Compare prices, services offered, and availability to find the best fit for your needs and budget.

3. Check for licensing and insurance
Ensure that the cleaning service you choose is licensed and insured. This protects you from any potential damages or accidents that may occur during the cleaning process. A reputable company will readily provide proof of their licensing and insurance upon request.

4. Inquire about their hiring and training process
Ask the cleaning service about their hiring and training procedures. A reliable company will conduct background checks on their employees and provide them with proper training to ensure consistent, high-quality service.

5. Discuss cleaning products and equipment
If you have specific preferences for cleaning products or if you have allergies or sensitivities, discuss this with the cleaning service. Some companies use their own products and equipment, while others may be open to using products you provide. Make sure to clarify this before hiring them.

6. Establish clear communication and expectations
Clear communication is key to a successful relationship with your house cleaning service. Discuss your expectations, preferences, and any concerns you may have. A good cleaning service will be open to your feedback and will work with you to ensure your satisfaction.

7. Consider a trial period
Before committing to a long-term contract, consider starting with a trial period. This allows you to evaluate the quality of their work and determine if they are the right fit for your needs. Many cleaning services offer a one-time or introductory cleaning session for this purpose.

Choosing the right house cleaning service may take some time and effort, but it's worth it to find a reliable and trustworthy company that meets your needs. At [Puget Sound Cleaners](https://pugetsoundcleaners.com/), we provide vetted, licensed, and insured cleaners to give you the highest quality service. By following these tips and hiring Puget Sound Cleaners, you can ensure a clean and comfortable home without the hassle of doing it yourself.
