These versatile constructs allow us to handle a variable number of arguments of the same type within a function.

## What are `Variadic Parameters`?

In Swift, **variadic parameters** enable a function to accept zero or more values of a specific type.  
They come in handy when you want to create a function that can take any number of arguments without specifying the exact count upfront.  
Imagine a scenario where you're dealing with a method that often works with individual elements, and you'd rather avoid creating an array just for a single value at the implementation level.

### How to Define a Variadic Parameter

To declare a variadic parameter, use a value type followed by three dots `...`.  
  
  
Here's an example:

```swift
mutating func add(_ newContent: Content...) {
    content.append(contentsOf: newContent)
}
```

In this snippet:

- `add(_:)` is a method that can accept either a single value or multiple values at once.
- The `Content` type represents the elements we're adding to our collection.

You can now call this method with one or more `Content` instances:

```swift
var posts = BlogPosts()

// Add a single content item:
posts.add(Content(title: "Blog post 1"))

// Add multiple items:
posts.add(
    Content(title: "Blog post 2"), 
    Content(title: "Blog post 3")
)
```

### Handling Multiple Variadic Arguments

Since Swift 5.4 (shipped with Xcode 12.5), you can define multiple variadic arguments in a method:

```swift
mutating func add(_ newContent: Content..., newUsers: User...) {
    content.append(contentsOf: newContent)
    users.append(contentsOf: newUsers)
}
```

This flexibility allows multiple parameters to receive zero or more values.

## Caveats / Limitations

While variadic parameters are powerful, they have some limitations to consider:

**Empty Variadic Arguments** : You can pass an empty array as a variadic argument. For instance:

```swift
struct BlogPosts {
    private(set) var content: [Content] = []

    mutating func add(_ newContent: [Content]) {
        content.append(contentsOf: newContent)
    }
}

var posts = BlogPosts()
    posts.add([])
```

The same applies when using variadic parameters directly:

```swift
struct BlogPosts {
    private(set) var content: [Content] = []

    mutating func add(_ newContent: Content...) {
        content.append(contentsOf: newContent)
    }
}

var posts = BlogPosts()
    posts.add()
```

**Type Consistency** : Variadic parameters must have the same type. You cannot mix different types within a single variadic argument.

## Conclusion

Variadic parameters are a powerful feature in Swift that allows you to create functions that can accept a variable number of arguments.

Promethues- Architecture
Published: 2024-04-22 04:30:03


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/24yc4c4717qz76e2nbf2.png)
Prometheus gathers metrics from your applications and infrastructure. These metrics represent various aspects of your systems’ performance, such as CPU usage, memory consumption, request latency, and more. Prometheus collects these metrics over time, allowing you to understand trends, identify anomalies, and troubleshoot issues.
Key Components of Prometheus Architecture
Prometheus Server: The core component responsible for data collection, storage, querying, and alerting.
Time Series Database (TSDB): Stores time-series data efficiently, enabling fast querying and analysis of metrics.
Data Model: Defines how metrics are organized using metric names, labels, and values.
Exporters: These are tools that expose metrics from third-party systems as Prometheus metrics. Since Prometheus can only scrape metrics in its
Service Discovery: services are identified which are need to scraped.
Alert Manager: Handles alerts sent by the Prometheus server. It is responsible for deduplicating, grouping, and routing them to the correct receiver such as email, PagerDuty, or OpsGenie. It also takes care of silencing and inhibition of alerts.
Pushgateway: A middleware component that accepts metrics from jobs that cannot be scraped. This is typical for short-lived jobs or batch jobs that don’t expose an HTTP endpoint long enough for Prometheus to scrape. Metrics are pushed to the Pushgateway, and then Prometheus scrapes the Pushgateway to collect these metrics.
Targets: Any system or service that exposes metrics via an HTTP endpoint. This could be applications, infrastructure components, or external services.
Client Libraries: Libraries for instrumenting applications and services to expose their own metrics in a Prometheus-compatible format.
PromQL: The query language used to query and analyze metrics stored in Prometheus.
Visualization Tools: Various tools and dashboards can be used to visualize the metrics collected by Prometheus, such as Grafana.

How to edit a table's cell with VTable?
Tags: vtable, data, visualization
Published: 2024-04-22 03:29:55

## Title
Can an editable table enter the editing state directly when clicked, instead of double clicking a cell to make it editable?

## Description
In the table editing scenario, double-clicking to enter the editing state would be cumbersome, and you need to enter the editing state directly.

## Solution 
You can configure editCellTrigger to click in the table initialization option. The configuration item is defined as follows:
```
/** Edit triggering time: double click event | single click event | api to manually start editing. Default is double click 'doubleclick' */
editCellTrigger?: 'doubleclick' | 'click' | 'api';
```

## Code Example
```
  const option = {
    records,
    columns,
    autoWrapText: true,
    limitMaxAutoWidth: 600,
    heightMode: 'autoHeight',
    editCellTrigger: 'click' // Set the edit trigger timing
  };
  const tableInstance = new VTable.ListTable(container, option);
```

Manchester United and Manchester City's England FA Cup Final
Published: 2024-04-22 02:49:37

The final of the FA Cup will be held as the Manchester Derby for the second consecutive year.

Manchester United (Manchester United) of the English Premier League won the penalty shootout 4-2 after drawing 3-3 in the FA Cup semi-final against Coventry at Wembley Stadium in London on the 22nd after a 120-minute extended struggle.

Manchester United players are delighted to secure a 4-2 win in the shootout. 

Manchester City, which defeated Chelsea the previous day, will play in the final match at Wembley Stadium on May 25. Manchester United, which lost 1-2 to Manchester City in the FA Cup final last season, has a chance to avenge it.

Manchester United won the game, but it was a rollercoaster ride between heaven and hell.

He got off to a good start. Scott McTominay's first goal in the 23rd minute gave Manchester United the lead, before Maguire's header in extra time gave the team a 2-0 lead. Bruno Fernandes scored his third goal in the 13th minute of the second half, which seemed to easily secure the win.

However, Coventry scored a dramatic tie in the 26th minute, starting with Ellis Sims' pursuit goal, Callum O'Hare's additional goal in the 34th minute of the second half, and Manchester United Aaron Wan-Bissaka's handball foul in the extra time.

The two teams, which failed to secure a win for 90 minutes in the first half and the second half, went into extra time. Coventry hit the ground after Victor Thorpe scored a goal in extra time in the second half of extra time, but VAR declared offside.  [안전놀이터 추천](https://www.cmriindia.org/esports-betting-site/)

In the end, the two teams went into a penalty shootout, with United winning 4-2 and confirming their place in the final.
Common Forex Trading Mistakes to Avoid
Published: 2024-04-22 02:39:08

**Lack of a Trading Plan**
One of the most common mistakes of new forex traders is lacking a trading plan. A trading plan outlines how a trader will find and execute trades, including under what conditions they will buy and sell, how large of a position they will take, what can be traded, and other related rules. Without a trading plan, traders are likely to carry out impulsive trading.

**Overtrading**
Another common mistake is overtrading. This happens when a trader opens too many positions at a time or trades too frequently. Overtrading often leads to poor decision-making, which will then give rise to higher transaction costs and risks.

**Using data APIs with delayed data**
Forex markets are highly dynamic. It is important to choose real-time Financial Market Data APIs wisely. Using a market data API with delayed data may cause traders to fail to capture the swift price movements, limiting the ability to make timely decisions. Hence, it is crucial to choose a reliable API like AllTick Financial Market Data APIs (https://alltick.co/en-US), which covers real-time for over 100 currencies.

**Not Using Stop-Loss Orders**
In forex trading, stop-loss orders are indispensable for risk management. With stop-loss orders, traders can set an exit point for a position, restricting the possible losses. 
Not utilising stop-loss orders may result in significant losses if a trade goes against a trader.

**Failing to Adapt to Market Conditions**
Forex markets are ever-changing. Traders have to keep up with the changes and adapt to the new market conditions to prevent losses or missed opportunities.

**Trading Without a Clear Strategy**
A clear trading strategy is much needed for trading forex successfully. Without one, it is likely to make poor decision-making.

**Lack of Patience**
Forex trading requires patience. Traders who are too eager to make a profit may be more likely to make impulsive decisions that lead to losses.


All in all, while forex trading presents lucrative opportunities, success hinges on knowledge, discipline, and prudent decision-making. By sidestepping the common pitfalls mentioned above, you can enhance your performance and navigate the forex markets more effectively
Yet Another Newsletter: Saying goodbye

This will be a short one. I've decided to shut down this newsletter. It's been fun gathering stuff I find interesting on a weekly basis, but it also takes time sometimes, and the newsletter hasn't really grown like I thought it would.

Having said that, I do want to thank all of you who have subscribed over the past couple of years.

It's not all doom and gloom, though. I'm going to be putting more of my energy into my live stream, [nickyt.live](https://nickyt.live) if you weren't aware, as well as what, I think, might be a bit more unique in terms of a newsletter/video shorts, [OneTipAWeek.com](https://onetipaweek.com).

MMOexp:Item Level Breakpoints Important
Published: 2024-04-22 02:19:00

 What are Item Power Breakpoints in [Diablo 4 Gold](www.mmoexp.com/Diablo-4/Gold.html)?
Item level Breakpoints are hidden stats that can bring your weapons and armor up a statistic tier based on the power level. There is a universal layer of tiers in Diablo 4 that can provide a massive buff to all stats based on the power level tier that you jump. This is all done through the upgrade system at any Blacksmith in the game.

Why are Item Level Breakpoints Important?
Although the breakpoints are essentially hidden, they dictate how useful a piece of armor is. When you find a new item that looks worthwhile and it has some decent stats, the next metric to check is the power level, If it falls just below one of the levels I listed above, then it’s usually better to wait.

Tracking the Item Level Breakpoints in Diablo 4 can save you time and resources when you’re looking for a specific build. Keep this in mind as you level and continue farming all those Sanctuary monsters until you have what you need.

There are tons of stats to keep track of in Diablo 4, and some of them don’t have a great explanation on the surface as you scroll through your equipment. Thorns are one of the many stats that can have a significant effect if you know how to utilize them, and I’m here to explain how they work on your armor. Here’s how Thorns work in [cheap Diablo IV gold](www.mmoexp.com/Diablo-4/Gold.html).

The Most Important Thing I learned About Writing Readable Code
Tags: webdev, beginners, programming
Published: 2024-04-22 02:07:00

Well, first of all, it lets other people understand our code.

You have probably found yourself in a codebase before.

You read it and you are just like, "I don't understand what the hell is going on around here."

And the temptation is just to like jump in and rewrite everything.

But, being able to write code where people can really easily read it is something that other developers on your team will really appreciate.

And that is what often is the difference between them looking at you as a junior developer and a senior programmer.

Rooting for you,

For week 7, this was the comeback week in where we are all present the whole week since for the past few weeks its either we have an activity at school that we need to be absent in our ojt or there's a holiday during the week, so this week was a bit different and tiring. Anyways, for my task, it was all the same as last week where I have to do my tasks. The difference was that I had to teach another intern from another school the task that I was doing since he was suddenly told by our manager that he will be learning some warehouse task in which I was assigned, so I was tasked to let him observe me on how to process my task as well as taught him the right process. Everything else went smoothly for this week of internship.
