Run Task Scheduler in Silent Mode
Tags: beginners, tutorial, productivity, windows
Published: 2023-08-14 07:18:51

Automating mundane task via Task Scheduler is a no brainer.
And making them run in silent mode i.e. not seeing the command prompt pop up every time it runs is a huge win.

For example, if your mundane task is automated via script in a batch file (.bat), you can run your batch file e.g.:(`run.bat`) in silent mode without the command prompt window popping up.

To do this, you can use the `start` command along with the `/B` flag. Here's how you can modify your batch file:

```batch
@echo off
# cd \Path\to\YourAutomationProject
cd C:\User\UserName\daily-automation

# Example of task automation with Python
start /B pythonw.exe daily_automation.py
```

Explanation:

1. The `start` command is used to start a separate window to run a specified program or command.

2. The `/B` flag is used to start the application without creating a new command prompt window. This is what allows the script to run silently.

3. Replace `python` with `pythonw.exe`. The `pythonw.exe` is similar to `python.exe`, but it runs in the background without showing a console window. This helps achieve the silent mode you're looking for.

Please note that the behavior of `pythonw.exe` can vary depending on the specific Python version you have installed. In some cases, you might need to use `python.exe` and pair it with other techniques to hide the console window.

Also, ensure that the paths provided in your batch file are accurate and the files are located in the specified directories.

Good luck!
Automation is king.
Git Remotes for Beginners: Inspect, Rename and Remove
Tags: git
Published: 2023-08-14 07:17:40

In the [previous post, I introduced you to the concept of Git remotes](https://poddarayush.com/posts/git-remote-commands). I showed you that a Git repository can have more than one remote and how you can fetch data from a particular remote.

In this post, I am about to answer the following questions:
1. How do you view more details about a particular remote? The branches present in the remote, and how those branches map to your local branches.
2. How do you rename a remote?
3. How do you stop tracking (remove) a remote from your Git repository?

## View (Inspect) a Git remote
The command to achieve this is: `git remote show <shortname>`. For example, the sample output of running `git remote show origin` is shown below.

```bash
* remote origin
  Fetch URL: git@github.com:ayushpoddar/colorls.git
  Push  URL: git@github.com:ayushpoddar/colorls.git
  HEAD branch: main
  Remote branches:
    color-hidden-files  tracked
    main                tracked
    show-abs-path-xargs tracked
    size-in-bytes       tracked
  Local branches configured for 'git pull':
    color-hidden-files  merges with remote color-hidden-files
    main                merges with remote main
    show-abs-path-xargs merges with remote show-abs-path-xargs
    size-in-bytes       merges with remote size-in-bytes
  Local refs configured for 'git push':
    color-hidden-files  pushes to color-hidden-files  (up to date)
    main                pushes to main                (up to date)
    show-abs-path-xargs pushes to show-abs-path-xargs (up to date)
    size-in-bytes       pushes to size-in-bytes       (up to date)
```

I want you make the following observations:
- This command outputs the full URL of the remote that the shortname is mapped to.
- The list of branches in remote have been "fetched" to your local repository.
- It lists the mapping between your local branches and remote branches. This helps you with knowing the remote branch that will be used when running `git pull` or `git push` on a local branch.


> If you are wondering if the branch names in remote and the corresponding branch names in local can be different, I would encourage you to read [this Github article](https://docs.github.com/en/get-started/using-git/pushing-commits-to-a-remote-repository#renaming-branches).

## How to rename a remote shortname?
Simple command.

```bash
git remote rename <old-shortname> <new-shortname>
```

## How to remove a remote?
If you want to stop tracking a remote, you need to remove all references to the remote from your local repository. The command to do so is:

```bash
git remote remove <shortname>

# rm is an alias for remove
git remote rm <shortname>
```

## Final words
After reading the [first post](https://poddarayush.com/posts/git-remote-commands) and this post, you are equipped enough to understand any advanced ideas or commands that you may encounter. You can explore more on your own using `man git-remote` or `git help remote`.

What is a Module?
Tags: javascript, beginners, api, node
Published: 2023-08-14 07:14:00

Hearing of the word **"Modules or Node_modules"** and wondering exactly what it is?

Now you're at the right place, think of a box containing some pieces of items it could be simply anything {some pieces of metals, used items and the likes...}.

Now that box is exactly what Module is and those contents are your simple and complex lines of codes, so I am saying your {index.html, style.css, app.tsx, header.js} and so more are simply your modules and the lines of codes in it are what made up the module.

So Bingo! now you know what a module is, come back here for another pieces of my contents...
Posgresql Optimization: GIN indexes and Cluster Operation
Tags: postgres, postgressql, apacheage
Published: 2023-08-14 07:09:44

## GIN Indexes
In the regular index structure, a single key is normally associated with either one or multiple values, so finding the desired index entries are relatively simple. But the structure Generalized Inverted Index (GIN) holds is different. 

For GIN index, a value can have multiple key associated with it. Like GiST, user-defined indexing strategies can be implemented on GIN. It is also a way of implementing full-text search.

## Cluster operation
In Postgres database, reading records randomly from disk is normally considered 4 times expensive than sequence disk read. If records in the database table are randomly distributed, retrieving more than one record will take longer time because of random data access. 
Clustering a database table using an index will reorganize the order of data records according to the index order, which in turn will reduce the number of random disk access and speed up the process.

The approach Postgres has taken for clustering is different from the SQL Server and DB2, there is no additional penalty during transactions of having a clustered or clustering index, it does not try to maintain the physical order of records and all new data goes to the end of the table. 
`CLUSTER` is not a one-time operation; one has to run CLUSTER every now and then to reorganize the order of records. After the first time of clustering, Postgres will remember which index it was clustered by. 
During the process of clustering, an exclusive lock is acquired on the table, which will block other transaction from accessing. It is also a time consuming process depending on the data size it holds and the workload of the server. 
> So it is recommended to run during evenings and weekend when others will not be disturbed. 
Also remember to run `ANALYZE` after clustering to update the database statistics.

In the next article, we'll consider another two important optimization techniques: `Bitmap index scan` and `Bitmap heap scan`
Should I use both client side and external connection pooling together?
Tags: database, databaseconnection, connectionpooling
Published: 2023-08-14 07:06:38

When it comes to database connection pooling, software developers often find themselves faced with the question: should I use both client-side and external connection pooling together? It's a valid question, and one that requires careful consideration. Let's dive into the topic and explore the pros and cons of using both types of connection pooling simultaneously.

First, let's quickly understand what client-side and external connection pooling are. Client-side connection pooling is a technique where the application itself manages the connection pool. On the other hand, external connection pooling involves using a separate component or service to handle connection pooling.

Now, let's look at the advantages of using both types of connection pooling together:

*   **Improved performance:** By combining client-side and external connection pooling, you can leverage the benefits of both approaches to achieve optimal performance. Client-side pooling allows for efficient reuse of connections within the application, while external pooling provides additional scalability and load balancing capabilities.
*   **Redundancy and failover:** Using both types of connection pooling can provide redundancy and failover capabilities. If one connection pool fails, the application can fall back to the other pool, ensuring uninterrupted access to the database.
*   **Flexibility:** Different parts of your application may have varying connection pooling requirements. By using both client-side and external pooling, you can tailor the pooling strategy to specific components or modules within your software, providing flexibility and optimization.

However, there are some considerations to keep in mind when deciding whether to use both types of connection pooling:

*   **Increased complexity:** Implementing and managing both client-side and external connection pooling can add complexity to your application. It requires careful configuration and coordination between the two pooling mechanisms.
*   **Overhead:** Using both types of pooling may introduce additional overhead, as the application needs to maintain and manage two separate connection pools. This can impact resource utilization and performance.

In conclusion, whether to use both client-side and external connection pooling together depends on your specific requirements and the complexity of your application. It can provide improved performance, redundancy, and flexibility, but at the cost of increased complexity and overhead. Consider your application's needs and weigh the pros and cons before making a decision.

Postgresql Optimization: Hash Index and GiST
Tags: postgres, postgressql, apacheage
Published: 2023-08-14 07:00:13

## Hash Index

`Hash index` can locate records very quickly when only equality comparison is involved in the searching on an index. The `hash index` entry is organized in key and value pairs, where the value point to the table record(s) contain(s) the key. 
Given a key, it requires only one or two disk reads to retrieve the table record. It was quite a popular index algorithm in the days when memory was relatively expensive and using `B-tree index` caused more disk reads. However in Postgres, `hash index operations are not WAL- logged, which means it has to be rebuilt manually after system failure.`

*Because of the difficulty in maintenance, it is not recommended of implementing Hash index in production system.* `B-tree index` is considered as a good alternative for handling equity comparison.

## GiST
B-tree index in Postgres can handle basic data type comparison like numbers and strings using balanced tree structure. In case of customized data type or advanced data type, using the B-tree index could not able to improve the performance. In order to optimize this kind of data types, `Generalized Search Tree (GiST)` is introduced in Postgres. 
It is an extensible data structure, which a domain expert can implement for appropriate access method on customized data types or data types that go beyond the usual equality and range comparisons to utilize the tree-structured access method. GiST is also used in full text search by several of contrib modules.

In the next article, we'll dsicuss `GIN indexes` and `Cluster operation`

PostgreSQL Optimization: B-tree index
Tags: postgres, apacheag
Published: 2023-08-14 06:47:28

`Balanced tree index` is considered as the most efficient index type in Postgres database system. As name implies, the index structure is balanced between its left and right side.

Theoretically it requires same travelling distance to any leaf page entry. It can be used to locate a single value or a range of values efficiently if the indexed column is involved in comparison categories of:
- equalgreater than, 
- smaller than or 
- combinations of these operators. 

B-tree index can also assist in string comparisons such as `LIKE`, pattern matching if the comparison tries to match the beginning part of the column. However in case of string comparison, if your database uses other locale other than C, one will need to create index with a special mode for locale sensitive character by character comparison.

In the next article, we'll consider `Hash Indexes` and GiST.
ReactJS useContext Hook

Published: 2023-08-14 06:30:56

**useContext() Hook**

Context provides a way to pass data through the component tree without having to pass props down manually at every level.

- Step 1: Create Context Component
  eg:
    // MyContext.jsx
     import React,{ createContext } from “react”
     const MyContext = createContext();

     export default MyContext;

- Step 1: Using Context Provider

eg:
// App.js
import React from 'react';
import MyContext from './MyContext';
import ChildComponent from './ChildComponent';

function App() {
  const contextValue = {
    name: 'John',
    age: 30,  };

  return (
    <MyContext.Provider value={contextValue}>
      <div className="App">
        <ChildComponent />
      </div>
    </MyContext.Provider>
  );
}

export default App;


- Step 3: Using useContext hook
eg:

// ChildComponent.js

import React, { useContext } from 'react';
import MyContext from './MyContext';

function ChildComponent() {
  const context = useContext(MyContext);

  return (
    <div>
      <p>Name: {context.name}</p>
      <p>Age: {context.age}</p>
    </div>
  );
}
export default ChildComponent;
