Olimpio — Sun, 07 Feb 2021 16:22:31 +0000

Hello guys... I need your help... When (quickly) navigating on my react website... I get this error on the console. I heard I need to use the cleanUp function in order to correct this error. But I am using firebase firestore to fetch the data so I dont know how to solve this error...
Here is the error on the console

Here is the code of the useEffect hook I am using...

useEffect(() => {
    const fetchDb = db.collection('posts');

    fetchDb.get()
      .then(response => {
        const fetchedPosts = [];
        response.docs.forEach(post => {
          const fetchedPost = {
            id: post.id,
            ...post.data()
          };
          fetchedPosts.push(fetchedPost);
        });
        setPosts(fetchedPosts);
        setIsLoading(false);
      })
      .catch(error => {
        error = 'Houve um erro'
        setError(error);
      });
  }, []);

How can I share the same domain with two different servers?

Olimpio — Sat, 28 Sep 2019 06:39:16 +0000

Is it possible to have two separate servers share the same domain name? If so, how?

I have a website and email services hosted on a nginx server with the domain name site.co.mz, working perfectly.

But recently I'm developing a new website that should replace the one hosted on this nginx server. I've hosted this new website on Heroku because I'm developing this website using Jekyll and some gems which Heroku makes it easy to host and it's working perfectly too.

I want to know if is it possible to share the same domain name site.co.mz on these two different servers?

TIL: How does .chomp method works?

Olimpio — Sun, 17 Feb 2019 22:49:13 +0000

As I'm learning Ruby on Codecademy I've come across many methods and I'm learning many things. But as I want to master this language, I'm taking some time to dive into some new things I learn every day. Today I want to go in depth on:

How does `.chomp` method work?

First of all, put in mind that Ruby is an Object Oriented language and everything in Ruby is an object. So, when we call the .chomp method on a value/object it removes the line break.

Actually, what .chomp does, is removing the Enter character at the end of your string. When you type d e v t o, each character at a time and then press Enter gets takes all the letters and the Enter. Remember that Enter is just another character in Ruby.

For example:

input = gets # get a string
Bem Vindo
=> "Bem Vindo\n" # when you hit the enter keyboard it adds a character

Now let us remove that enter character

puts input.chomp

or we can remove right away when typing it

input = gets.chomp # gets require a string as input and chomp will delete the line break that comes with that string

gets is your User's input. Also, it's good to know that gets or puts, mean get string or put string for puts. That means these methods are dealing with strings only.

We can even use the .chomp method to remove a substring of a string in that way.

str = "Hello"

str.chomp("lo")

Thanks.
