How to Show Indexes in MySQL Tables & Database
Tags: mysql, mariadb, database
Published: 2024-04-09 10:41:20

Managing data from small or large databases is a daily task of database administrators and developers. Frequently, they need to search for specific data processing thousands of rows. This can be complicated with large databases and may lead to potential performance issues.

For example, you need to retrieve a list of products with total sales equal to or less than the specified value - 20000. You execute a SELECT * FROM query with the WHERE clause, and MySQL scans each row one by one to check if it satisfies the specified condition. In the output, the matching rows are added to the result to be returned. If MySQL cannot find the required values, it scans each row until the end of the table. What if the data is fetched from a large table? This could waste a significant amount of your time and resources and lead to poor performance. So, indexes may help resolve performance issues with large tables.

An index in MySQL is a data structure that may speed up data retrieval on a table. It arranges values in such a way, so MySQL can quickly find specific rows based on indexed columns without having to scan the full table.

In the article, we'll explore the basics of indexes and their different types available in MySQL. We'll also examine methods for showing indexes and querying specific index information.

GUI for fastlane?
Tags: flutter, ios, fastlane, android
Published: 2024-04-09 10:16:19

Hello mobile app developers 🍃

**I'm building a GUI for fastlane for build and release automation.**

I worked with fastlane for a couple of years now, and got tired of having to go back and read the same docs I forgot, and configure new lanes for my apps, etc.

The idea is a simple and intuitive app that wraps fastlane commands and guides you step-by-step through the standard process for configuring Flutter app releases.

I put together a [one page website](https://fastlaneui.framer.website) to explain the reason to use it - is this interesting to you?
Odoo : Inherit base menu and add groups to it
Tags: odoo
Published: 2024-04-09 10:06:24

While using Odoo development, you often get a use case to extend a base menu and add some custom group to it to restrict the access. Assuming the xml way of adding attributes to field, we may tend to do the same menu items in Odoo, sadly this will not work. Below is the proper way to extend and add user groups to a  base menu. 

For example we have menu item  - **purchase.menu_product_pricelist_action2_purchase** - and we have a custom user group that is - **custom_module.group_access_price_suppliers** -  now we need to add this new user group to the menu item. In order to do that we shall create a security.xml in our custom module and add below code to that

```
 <record id="purchase.menu_product_pricelist_action2_purchase" model="ir.ui.menu">
            <field name="groups_id" eval="[(6, 0, [ref('ambala.group_access_price_suppliers')])]"/>
        </record>
```

This code snippet is from an XML file in an Odoo module, and it's used to define a menu item in the Odoo user interface. Let's break down the code:

xml
Copy code
<record id="purchase.menu_product_pricelist_action2_purchase" model="ir.ui.menu">
    <field name="groups_id" eval="[(6, 0, [ref('ambala.group_access_price_suppliers')])]"/>
</record>
<record>: This tag is used to define a new record in Odoo's database. In this case, it's defining a record for a menu item.

id="purchase.menu_product_pricelist_action2_purchase": This assigns a unique identifier to the record. This ID is used to reference this record from other parts of the code.

model="ir.ui.menu": Specifies the Odoo model for which the record is being defined. In this case, it's defining a menu item (ir.ui.menu).

<field name="groups_id" eval="[(6, 0, [ref('ambala.group_access_price_suppliers')])]"/>: This line sets the groups_id field of the menu item record. The groups_id field is used to specify which user groups have access to this menu item.

eval="[(6, 0, [ref('ambala.group_access_price_suppliers')])]: This part evaluates to a Python expression that defines the access groups for this menu item.
(6, 0, [ref('ambala.group_access_price_suppliers')]): This is a tuple with three elements:
6: This indicates that the operation is to replace the existing records with the given list.
0: This is the ID of the record to be replaced. Since it's 0, it means it's creating a new record.
[ref('ambala.group_access_price_suppliers')]: This is a reference to a user group defined in the system. ambala.group_access_price_suppliers likely represents a user group called "Price Suppliers" defined elsewhere in the code. It specifies that members of this user group will have access to this menu item.

if we want to just add the custom user group but keeping all the existing group then do the below 

```
 <field name="groups_id" eval="[(4, ref('your_custom_group_id'))]"/>

```

Speak Everyone's Language: A Guide to Multilingual React Apps! 🔯
Tags: webdev, react, javascript
Published: 2024-04-09 09:56:32

In today's world, speaking everyone's language is super important for websites and apps. React, a cool tool for making websites, has some awesome tricks to help with that! In this blog, we're going to dive into how you can easily make your React app understand many languages. It's going to be fun, simple, and totally doable!

## Cool Ways to Make Your App Multilingual:


### 1. DIY Translations:

We can start by doing it ourselves! Think of it like having a secret decoder ring for each language.
We'll create special files for each language, like having different dictionaries.
Then, when our app starts, we'll pick the right dictionary based on the language someone wants.

![Languages folder](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pq77es1eux9hlhzrurgs.png)

### 2. React-Intl Magic:
React-Intl is a powerful library for internationalization (i18n) in React applications.
It's like having a language wizard in your app. It can do things like change numbers, dates, and words into any language.

```
import React from 'react';
import { FormattedMessage, IntlProvider } from 'react-intl';

const messages = {
  en: {
    greeting: 'Hello!',
  },
  fr: {
    greeting: 'Bonjour!',
  },
};

function App() {
  const [locale, setLocale] = React.useState('en');

  return (
    <IntlProvider locale={locale} messages={messages[locale]}>
      <div>
        <h1><FormattedMessage id="greeting" /></h1>
        <button onClick={() => setLocale('en')}>English</button>
        <button onClick={() => setLocale('fr')}>French</button>
      </div>
    </IntlProvider>
  );
}

export default App;
```
Similar way there is also one library named `i18next`

Tip: Use the Laravel Arr helpers directly instead of using temporary collections
Tags: laravel, tips, tutorial, beginners
Published: 2024-04-09 09:44:06

Here's another quick Laravel tip: Instead of creating a temporary collection just to use array helpers, you can use the Laravel `Arr` helpers directly.

This makes the code much more readable, as you don't need the cognitive load of having to consider the `collect()` logic and also having to convert it back to an array with `all()`.


```php
use Illuminate\Support\Arr;

// Do this 👇
Arr::mapWithKeys($array, function (array $item, int $key) {
    return [$item['email'] => $item['name']];
});

// Instead of this 👇
collect($array)->mapWithKeys(function (array $item, int $key) {
    return [$item['email'] => $item['name']];
})->all();
```
Lots of debug log is written after commons-logging is upgraded to 1.3.0
Tags: log4j, logging, java
Published: 2024-04-09 09:31:59

## Background

The default log level of our applications is `DEBUG` because we aim to separate informative logs from diagnostic logs.

Recently, we received a vulnerability warning from `commons-configuration2`, prompting us to update the version. After the update, the application runs fine; however, the size of our log has grown from hundreds of kilobytes to a few gigabytes.

## Investigation

The update of `commons-configuration2` also upgraded `commons-logging` to version `1.3.0`, which includes `log4j-jcl`. Previously, `log4j-jcl` was a standalone dependency. Now, all dependencies in our application (mainly `commons-beanutils`) are capable of writing logs through `log4j` loggers.

## Solution

We modified `log4j2.xml` to suppress the excessive logging by package. In the long term, we may need to introduce a custom log level between `INFO` and `DEBUG` as our default log level; and have a fine grained logging configuration.

Data Engineering Zoomcamp Week 6 - using redpanda 1
Published: 2024-04-09 06:43:52

This week we explored using redpanda as a drop in for kafka.
Using redpanda can be ran from a docker container.

Steps:
Copy the docker-compose.yml file into your install directory (this is a replica of what we used for the course).

```
version: '3.7'
services:
  # Redpanda cluster
  redpanda-1:
    image: docker.redpanda.com/vectorized/redpanda:v22.3.5
    container_name: redpanda-1
    command:
      - redpanda
      - start
      - --smp
      - '1'
      - --reserve-memory
      - 0M
      - --overprovisioned
      - --node-id
      - '1'
      - --kafka-addr
      - PLAINTEXT://0.0.0.0:29092,OUTSIDE://0.0.0.0:9092
      - --advertise-kafka-addr
      - PLAINTEXT://redpanda-1:29092,OUTSIDE://localhost:9092
      - --pandaproxy-addr
      - PLAINTEXT://0.0.0.0:28082,OUTSIDE://0.0.0.0:8082
      - --advertise-pandaproxy-addr
      - PLAINTEXT://redpanda-1:28082,OUTSIDE://localhost:8082
      - --rpc-addr
      - 0.0.0.0:33145
      - --advertise-rpc-addr
      - redpanda-1:33145
    ports:
      # - 8081:8081
      - 8082:8082
      - 9092:9092
      - 28082:28082
      - 29092:29092

Top 10 Software Quality Assurance Tools For The Professionals
Tags: qualityassurancetools, qualityassuran, qa, salesforceqa
Published: 2024-04-09 08:57:25

In the software development lifecycle, these QA tools act like a toolkit that can help you to validate, inspect and perfect the processes before they go live. Undoubtedly, there are multiple tools that you can use as a professional, but we are listing the top ten tools that you must add to your bucket list.
01. Selenium
Selenium is one of the best open-source automated web automation tools that allow users to execute testing for web applications. It is also used on various platform testing applications and supports many programming languages. Therefore, this tool is appropriate for professionals who want a flexible QA testing solution.
02. TestLink
TestLink is a test management platform that assists the quality assurance engineers in tracking, planning and making reports on the test efforts.
It is specifically helpful for those teams working on agile projects and looking for a QA tool to help them manage the complete testing process in software development.
03. Apiary
It is an API software testing tool on a cloud-based platform for building, testing and designing APIs. Thus, it is beneficial for documentation, collaboration, and integration with popular frameworks and programming languages.
This tool is helpful for QA professionals who require API management and testing solutions. You should know that this tool is available online on a subscription basis.
04. Cypress 
It is an open-source quality assurance automation tool that supports multiple testing types using JAVAscript, like API, end-to-end, and component testing. Cypress is a complete tool that is helpful for automated testing and supports running various tests in a single framework.
05. Playwright
Playwright is an open-source automation tool or framework that Microsoft uses. It is also similar to Cypress because it is an end-to-end automation testing tool supporting API testing. It helps to maintain a single framework for different testing types.
06. Jmeter 
is an open-source platform quite famous for performance testing (It is a non-functional testing technique which helps to observe the speed, stability and responsiveness of an application under a given work pressure), but it is also used for API testing without any problem.
JMeter is useful because it offers a user interface that makes it easy to run complicated tests. 
Well , this is not the end there are other 4 [Quality Assurance Tools](https://s2-labs.com/blog/quality-assurance-tools/) that you need to master.
