Traits In PHP
Tags: php, webdev, laravel, oop
Published: 2024-03-12 16:46:20

PHP only supports single inheritance, but with the use of traits, we can achieve multiple inheritance.

A trait in PHP is like a set of reusable functions that you can add to different classes. It's a way to share code between classes without using regular inheritance.

Lets take an example:-

**1. Declare Trait**
   We can declare a trait with the `trait` keyword:

```
<?php
trait Trait1 {
    public function method1() {
        echo "Method 1 from Trait1!";
    }
}

trait Trait2 {
    public function method2() {
        echo "Method 2 from Trait2!";
    }
}
?>
```
Above we have declared two traits.

**2. Use of Trait**
   To use a trait in a class, use the `use` keyword:

```
<?php
trait Trait1 {
    public function method1() {
        echo "Method 1 from Trait1!\n";
    }
}

trait Trait2 {
    public function method2() {
        echo "Method 2 from Trait2!\n";
    }
}

class MyClass {
    use Trait1, Trait2;
}

$obj = new MyClass();
$obj->method1(); // Output: Method 1 from Trait1!
$obj->method2(); // Output: Method 2 from Trait2!
?>
```

I hope You understand the concept of traits.

Tags: webdev, javascript, beginners, programming
Published: 2024-03-12 16:14:23


In an intriguing turn of events, following a significant price rally witnessed by nearly all of the meme coins trading within the cryptocurrency realm, a substantial slump pulling the prices down has piqued the interest of crypto market traders and investors globally. Amid this slump witnessed, insights unveiled by the tracker Spotonchain, showcasing massive SHIB & PEPE dumps to CEXs, gained notable traction as it potentially hinted at a meme coin season end.
With SHIB and PEPE prices down 4-10% today, these selloffs birthed a pool of bearishness, as derivatives data for these tokens hinted at a downtrend in the broader crypto market. Meanwhile, other meme coins, such as FLOKI and DOGE also traded in the red today, aligning with the market sentiments of a potential meme coin season end.

SHIB & PEPE Prices Dip, Other Meme Coins Follow
As of writing, Shiba Inu’s price showcased a plunge of 4.52% over the past 24 hours and is currently trading at $0.00003265. PEPE coin’s price, on the other hand, was noted to fall by 9.84%, reaching $0.000008287.
Notably, the derivatives data for these tokens signaled a downtrend in the market, aligning with the slump as data showcased investors exiting or closing positions with a considerable plunge in market activity. Coinglass‘ data revealed a 5.87% dip in SHIB’s open interest and a 26.86% drop in volume, whereas the OI-weighted funding rate also slipped, reaching 0.0965%. Simultaneously, PEPE’s open interest plunged 8.06%, and volume plummeted 27.64%, whereas the OI-weighted funding rate fell to 0.1045%.

This collectively birthed a tidal wave of bearishness on SHIB & PEPE, while other meme coins like DOGE and FLOKI mirrored this bearishness.
As seen by investors across the global crypto realm, a substantial price slump witnessed by meme coins collectively appears to be birthing market sentiments of a meme coin boom coming to an end. This, in turn, triggers speculations over future colossal selloffs, pushing the prices down further.

Latency Under the Lens
Tags: webdev, beginners, devops, learning
Published: 2024-03-12 15:59:21

In the past, I was usually trying to fine-tune the code of my application, either by coding better or using the most performant tools and techniques. But in several recent jobs, I've noticed that the performance issue was not actually in the code but was "around" the application.

For example:

- Timeouts between the printer at the locations and my server - in the APM, the request processing time takes tens of milliseconds, so why a timeout?
- Long query time to database - but the query was optimized and ran a few milliseconds on the query client when tested.

The issue was high latency between the client and the server because of a nonoptimal geolocation deployment of servers.

For example, the database deployed in the west region while the application server was in the east region. In another case I had, the app servers and the database were on two different continents (Europe and the U.S.)

Nowadays, this issue is too common because provisioning servers is so easy, trying to keep cloud costs cheap and the separation between developers and the cloud infrastructure maintainers.

Let's demonstrate the issue by exploring the latency difference between a few countries. We will use https://wondernetwork.com/pings, one of the greatest sites I found a couple of years ago, telling the story of the importance of latency.


![Table of ping time between countries](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/erohd4maz5a7ao805zs4.png)

The website runs about 30 pings and shows the average; a ping is the time for the round trip between the sender and receiver (Client ↔ Server).

So, to establish the first TCP connection between a client and a server (Browser and Application Server, App Server and DB, etc.) - it takes ping-time X 1.5 to pass the 3-Way handshake.

![a graph of the TCP handshake](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ycmxq1rzalwe58o5c9tl.png)

Then, each transferring of packet of data will take the ping time. A standard TCP packet is up to 1.5KB, so to pass 15KB of data, you wait for at least a ping-time X 10 packets if none of the packets dropped in the middle.

Now imagine how long it takes to pass 100 records of shop listings with their full catalog and item descriptions between an app server in Europe and a database server in the U.S. Or how long it takes the browser to download your single-page application from your servers.

There are many ways to decrease the latency of your app, which I will elaborate on in the following posts in the latency series. but to name a few:
- Manually align the deployment of your servers in the same region on your cloud provider
- Working with private networks inside your cloud provider
- Using a CDN for static content
- Keeping connections alive between sender and receiver

This post was originally published on my newsletter, [Percentile 99th](https://percentile99th.substack.com/). If you wish to learn about the ways to decrease latency and more about application performance, I write about it extensively there.

E o voucher ein, Azure ? Vai ter ou não ?

Fiz o desafio da Microsoft learning que oferecia um voucher e no final não o citavam mais, fui passado para trás ?

Para quem me conhece a mais tempo sabe que eu adoro promoções, se tem algo de graça por tempo limitado, essa coisa acaba de se tornar meu hiperfoco, foi assim que eu tirei a Amazon Practitioner e a OCI Fundamentals.a A mesma coisa foi quando eu recebi um convite para o desafio da Microsoft Learning para o curso Microsoft Azure Fundamental que dizia claramente que ao final você ganhará um voucher.

Entrando em outro dia para dar continuidade, me deparo que a mensagem mudou ( Nesta foto foi quando eu percebi que tinha caroço nesse angu) e que não mais história de voucher, e agora como proceder ? Será que ele ainda vem ou já é comum esse tipo de atidude da Azure?

Django - "manually" revert a migration.
Tags: django, migration, revertmigration
Published: 2024-03-12 14:51:03

Backup everything (DB, code) before you doing this. Be extra cautious if you are doing this on Production db/environment.

Steps are as below:

- Delete the corresponding row in django_migrations table.
- Revert/delete tables and/or any other changes made by the migration. Be careful with this step and make sure after this, your Django system state (db/files) is the same as before migration.
- Remove the migration file (in app/migrations/00xx_<migration name>) if you need to.

Notes:
- Try to do this on a Test Django app to see that this is simple.
