PostgreSQL indexing: Hash Index
Tags: postgres, database, apache, age
Published: 2023-07-25 11:18:11

PostgreSQL offers a wide array of options for database indexing, hash indexing being one of them. In this article, we'll explore the fundamental theory and structure of hash indexing and its implementation in PostgreSQL.

A hash index is a database indexing method that utilizes a hash function to map keys to corresponding values. Hashing is a technique to associate a small number with a value of any data type to access data for situations where keys are relatively small and the data set remains static, in PostgreSQL.

## Architecture of Hash Index

Meta Page is the initial page in the hash index and holds essential information about the index's contents. It also has Bucket Pages which are the primary pages of the index, where data is stored in the form of "hash code - TID" pairs. TID stands for "tuple identifier" and helps locate the actual data in the table. Overflow Pages have a structure similar to bucket pages and are used when a single page is insufficient to hold all the data for a specific bucket. Finally, Bitmap Pages maintain a record of overflow pages that are currently clear and can be reused for other buckets, improving the efficiency of the index.

## Hash Index in PostgreSQL

Hash indexing in PostgreSQL uses the hash function to calculate an integer hash code for each value in the indexed column. At first, the hash index contains a small number of buckets, but this dynamically increases as the index grows to accommodate data efficiently. When inserting data into the hash index, the hash code determines the specific bucket where the data is stored. The data is organized as "hash code - TID" pairs, with the TID serving as a pointer to the actual data location in the table. 

If different values produce the same hash code, PostgreSQL uses either open addressing or chaining. Open addressing involves searching for the next available bucket in a specific sequence until an empty one is found, while chaining stores multiple values in the same bucket or overflow pages. Bitmap pages are employed to manage the allocation of overflow pages effectively. 

Hash indexing is most effective for static datasets with relatively small keys, providing rapid data access for read-intensive workloads in PostgreSQL.

JavaScript "textContent" vs "innerHTML"
Tags: javascript, webdev, programming, tutorial
Published: 2023-07-25 10:50:01

In JavaScript, both the `innerHTML` and `textContent` can be used to manipulate the text inside HTML elements.However, there is a slight difference between the two.

Let's see that difference in this article.

## `textContent` vs `innerHTML`

`textContent` is used to set the text between any tag.You pass the text as the string.


Whereas, `innerHTML` is used to pass any other HTML as the content of an HTML tag.

For the upcoming examples, we will use this HTML

```html
    <h1>Using innerHTML:</h1>
    <h2 id = "innerHTML"></h2>

    <h1>Using textContent:</h1>
    <h2 id = "textContent"></h2>
```

## Example of `textContent`

We have passed a string "Hello World" as the textual content of `h2`.

```js
document.getElementById("textContent").textContent = "Hello World";
```
Here, passing  any HTML tags as a string won't render as HTML.

**Output**


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/k5ojy3m64sa4fr34vozo.png)



## Example of `innerHTML`

Here, we passed some additional HTML `<em>Hello World</em>` in between the `h2` tags. That is why we got the output in italics

```js
document.getElementById("innerHTML").innerHTML = "<em>Hello World</em>";

```

**Output**

Error: error:0308010C:digital envelope routines::unsupported at new Hash
Published: 2023-07-25 08:38:24

The error message you're encountering seems to be related to an issue with OpenSSL, which is used by Node.js for cryptographic functions. The specific error message `ERR_OSSL_EVP_UNSUPPORTED` suggests that there might be a compatibility issue with the version of Node.js you're using (v18.16.1).

As of my last knowledge update in September 2021, the latest Node.js LTS version was 14.x. It's possible that Node.js v18.x has been released since then and might have introduced changes or compatibility issues.

To resolve this issue, I recommend trying the following steps:

1. Check the Node.js version requirements for your project. Ensure that the version of Node.js you are using is compatible with all the dependencies in your project, including `react-scripts`.

2. If you have multiple versions of Node.js installed, make sure you are using the correct version. You can switch between Node.js versions using a version manager like `nvm` (Node Version Manager).

3. Try reverting to the latest LTS version of Node.js (e.g., v14.x) to see if the issue persists.

4. If you are using a specific version of Node.js required by your project, try downgrading to a lower minor version within the same major version (e.g., from v18.16.1 to v18.15.x) to see if that resolves the issue.

5. If none of the above steps work, consider checking for updates or bug reports related to `react-scripts` and Node.js v18.x to see if there are any known compatibility issues.

6. If you're still facing issues, consider posting a question on a developer community or GitHub repository associated with `react-scripts` to seek help from the maintainers and other developers who might have encountered similar issues.

Remember that software ecosystems, including Node.js and its dependencies, are constantly evolving, and it's essential to ensure that all versions and dependencies are compatible with each other. If there are known issues or compatibility problems, using the recommended versions or seeking support from the community can often help resolve them.
