Code refactoring: what is it and why should you do it
Tags: refactoring
Published: 2024-03-28 10:28:47

There is a lot of talk and mention of refactoring in developer communities. But what is it exactly?

Some use refactoring as an **insult** - meaning your code is bad and it needs refactoring. Others use it as an **excuse** - meaning my estimations were wrong because I needed to refactor legacy code or when regression bugs happen because they were “refactoring” code.

## What is refactoring

Refactoring is the art of restructuring existing code without changing its external behavior. And this distinction without changing is really important.

Refactoring shouldn't be done while you are adding new features to the code. First, refactor old code and then proceed with adding a new feature.

[Martin Fowler](https://refactoring.com/) says that refactoring is a "series of small behavior-preserving transformations". And if he says so then who are you (or me) to question that 🫣

He continues that "each transformation does little, but a sequence of these transformations can produce a significant restructuring."" By making small changes it is less likely you'll break things.

Refactoring should not be a separate task that we'd add once in a while to our TO DO list. It should be a part of day-to-day programming.

## Why should you refactor your code?

You should consider refactoring as a part of your code hygiene - similar to washing your teeth or washing your hands. You don't question why - you just do it.

### Enhance readability and maintainability

Easier to read code is easier to fix. Both by you and your colleagues. You know, code is read more than it's written so it is important to be easy on the eyes.
The best way to learn the value of simple code is to be the person who has to pick it up again several months (or years) after it was written. Preferably in an emergency where you have to make and deploy a change very quickly, and also be confident that you're not going to take the system down.

### Improve extensibility and maintainability

Well-factored code is like Lego blocks. Easy to add a new feature to it, or to remove it if you don't need it anymore.

### Increase performance

Sometimes, by simplifying code, you inadvertently or intentionally fix an issue which improves performance.

### Reduce technical debt

Technical debt refers to accumulated code issues that make future development harder.

Refactoring helps you pay down this debt by fixing issues like duplicate code, unused variables, and poor naming conventions.

**However, refactoring shouldn't be done for its own sake.**
Always have a clear goal in mind, such as improving readability, fixing a bug, or adding a new feature.

*I'm giving a talk at the [Weblica conference](https://weblica.hr/en/) about code refactoring so if you are interested in learning more, do come by. This will be my first talk at a conference (I'm not counting meetup talks) and I hope it will be both informative and amusing.*

60 Years of the IBM System/360: A Legacy of Reliability and Security
Tags: mainframe, ibm, reliability, security
Published: 2024-03-28 10:14:48

In April, 7 1964, the world witnessed the birth of a technological titan – the IBM System/360, the first commercially successful general-purpose mainframe computer. Today, six decades later, the IBM mainframe continues to be a cornerstone of the global IT landscape, a testament to its enduring legacy of reliability and security.

Leave for loop now ! 🤔
Tags: javascript
Published: 2024-03-28 10:06:51

Can you guess what will be the output of

> https://codexdindia.blogspot.com/

```js
let cars2 = [4,5];
//cars2.length = 100;
cars2.forEach((car) => {
  console.log(car, "some text");
});
```
,
```js
let cars2 = [];
 cars2.length = 100;
cars2.forEach((car) => {
  console.log(car, "some text");
});
```
and
```js
let cars2 = [4,5];
 cars2.length = 100;
cars2.forEach((car) => {
  console.log(car, "some text");
});
```

I tried to create a new way of looping in JavaScript, because I liked the `forEach` loop and _I don't like the long formate of the for loop in js_. I tried to **invent** a new way of looping so I search [for loop javascript](https://www.w3schools.com/js/tryit.asp?filename=tryjs_loop_for) and edited [this code](https://cxdi.w3spaces.com/inventing-new-loop-type.html).

```html
<!DOCTYPE html>
<html>
<body>

<h2>JavaScript For Loop</h2>

<p id="demo"></p>

<script>
const cars = ["BMW", "Volvo", "Saab", "Ford", "Fiat", "Audi"];
let text = "";
cars.length = 100;
for (let i = 0; i < cars.length; i++) {
  text += cars[i] + "<br>";
}

document.getElementById("demo").innerHTML = text;
</script>

</body>
</html>
```

This worked fine ( you can change to `text += i + "<br>";` for getting counting )

the modification of array.length was working fine for the for loop.

but when I tried it with the `forEach` loop it's different. (a little bit obvious 😅) I thought I may be wrong at this but guess what even chatGPT given the wrong reply, it given the reply that I guessed at starting...

Rummy Satta
Published: 2024-03-28 10:02:58

In the realm of gaming and gambling, few activities blend skill and chance as seamlessly as Rummy Satta. This intriguing amalgamation of the classic card game Rummy with elements of betting, or "Satta" in Hindi, has garnered a dedicated following among enthusiasts seeking both mental stimulation and the thrill of uncertain outcomes.

Rummy, a game deeply rooted in tradition and strategy, is renowned for its rich history and widespread popularity. Originating from the United States in the early 20th century, Rummy has evolved into various forms, each with its own set of rules and nuances. The game typically involves arranging cards into sets and runs, employing strategic maneuvers to outwit opponents and declare victory.

On the other hand, "Satta" refers to the practice of betting or wagering money on uncertain outcomes, often associated with games of chance.

The fusion of [Rummy and Satta](https://rummy-satta.net/) creates a unique gaming experience that appeals to a diverse audience. At its core, Rummy Satta retains the fundamental mechanics of traditional Rummy, requiring players to meld cards into valid combinations while striving to minimize their points. However, the addition of betting introduces an element of risk and reward, elevating the stakes and intensifying the competitive atmosphere.

One of the key distinctions of Rummy Satta lies in its dynamic nature, where strategic prowess and calculated risks play pivotal roles in determining the outcome. Players must not only possess a thorough understanding of Rummy's rules and tactics but also navigate the complexities of betting, assessing probabilities and anticipating opponents' moves. This delicate balance between skill and chance ensures that every game is a riveting test of wits and nerve.

Furthermore, Rummy Satta fosters a sense of camaraderie and social interaction among participants, fostering bonds forged through shared experiences and mutual excitement. Whether played casually among friends or in organized tournaments with high stakes, the game cultivates a vibrant community of enthusiasts united by their passion for cards and the thrill of uncertainty.

However, it's essential to approach Rummy Satta responsibly, recognizing the potential risks associated with gambling and exercising restraint to avoid adverse consequences. While the allure of winning big may be enticing, it's crucial to maintain perspective and prioritize enjoyment over financial gain.

In conclusion, [Rummy Satta](https://rummy-satta.net/) stands as a testament to the enduring appeal of both Rummy and betting, offering a captivating fusion of skill and chance that captivates players worldwide. With its rich strategic depth, dynamic gameplay, and inherent excitement, Rummy Satta continues to enthrall enthusiasts, serving as a testament to the enduring allure of gaming in all its forms.
type script: hide column based on if the cells filled or not
Published: 2024-03-28 09:58:27

Hi,
I have this typescript to hide columns where all the cells are empty. But this doesn't work. Could you help me with correcting it? 
Thanks.  


function main(workbook: ExcelScript.Workbook) {
    const sheet = workbook.getActiveWorksheet();
    const tableRange = sheet.getUsedRange();
    const table = sheet.getRange(tableRange.getRow(), tableRange.getColumn(), tableRange.getLastRow(), tableRange.getLastColumn());
    const numRows = table.getNumRows();
    const numCols = table.getNumColumns();

    //sheet.setColumnWidths(1, numCols, 100); // Reset column widths

    // Loop through each column in the table
    for (let col = 1; col <= numCols; col++) {
        let visibleCount = 0;
        let bHide = true;

        // Loop through each row in the column's range
        for (let row = 1; row <= numRows; row++) {
            const cell = table.getCell(row, col);
            if (cell.getValue() !== '') {
                visibleCount++;
            }
        }

        // If there are any non-empty cells in the column, don't hide it
        if (visibleCount > 0) {
            bHide = false;
        }

        // Hide or show the entire column based on the visibility flag
        sheet.setColumnHidden(col, bHide);

Let's say we have a model structure that allows us to make comments on anything:

```rb
Comment.has_one :comment_commentee_tie

CommentCommenteeTie
  belongs_to :comment
  belongs_to :commentee, polymorphic: true

Post
  has_many :comment_commentee_ties
```

Now let's say we want to filter comments by possible post data. To alleviate the joining, we can define a non-polymorphic association for Comment:

```rb
Comment
  has_one :comment_commentee_tie
  has_one :post, through: :comment_commentee_tie, source: :commentee, source_type: "Post"
```

### Polymorphic children

Let's look at the harder case with `has_many :children, polymorphic: true`

We can use the scope option to filter what types of children we want:

```rb
Parent
  has_many :parent_child_ties
  
  has_many(
    :good_children,
    -> { where(child_type: "GoodChild") },
    through: :parent_child_ties,
    source: :child,
    source_type: "GoodChild"
  )
```
