 Viele Chaträume sind in der Lage, zu erkennen, wann ein Benutzer eine Verbindung herstellt oder unterbricht – dies wird dann allen verbundenen Nutzern im Chat angezeigt. Da du bereits ein Ereignis beim Verbinden und Trennen emittierst, musst du nur dieses Ereignis ändern, um eine solche Funktion zu implementieren. The most logical way of doing so is sending 3 pieces of data with the event: the username of the user who connected/disconnected, the current user count, and if that username connected or disconnected.
 
-Change the event name to `'user'`, and pass an object along containing the fields `username`, `currentUsers`, and `connected` (to be `true` in case of connection, or `false` for disconnection of the user sent). Be sure to change both `'user count'` events and set the disconnect one to send `false` for the field `connected` instead of `true` like the event emitted on connect.

 **Note** Privacy Considerations: Due to the requirement that only 1 like per IP should be accepted, you will have to save IP addresses. It is important to remain compliant with data privacy laws such as the General Data Protection Regulation. One option is to get permission to save the user's data, but it is much simpler to anonymize it. For this challenge, remember to anonymize IP addresses before saving them to the database. If you need ideas on how to do this, you may choose to hash the data, truncate it, or set part of the IP address to 0.

-HTTP Strict Transport Security (HSTS) is a web security policy which helps to protect websites against protocol downgrade attacks and cookie hijacking. If your website can be accessed via HTTPS you can ask user’s browsers to avoid using insecure HTTP. By setting the header Strict-Transport-Security, you tell the browsers to use HTTPS for the future requests in a specified amount of time. This will work for the requests coming after the initial request.

-BCrypt hashes are very secure. A hash is basically a fingerprint of the original data- always unique. This is accomplished by feeding the original data into an algorithm and returning a fixed length result. To further complicate this process and make it more secure, you can also *salt* your hash. Salting your hash involves adding random data to the original data before the hashing process which makes it even harder to crack the hash.
+BCrypt hashes are very secure. Ein Hash ist im Grunde ein Fingerabdruck der ursprünglichen Daten - immer einzigartig. This is accomplished by feeding the original data into an algorithm and returning a fixed length result. To further complicate this process and make it more secure, you can also *salt* your hash. Salting your hash involves adding random data to the original data before the hashing process which makes it even harder to crack the hash.
 
-BCrypt hashes will always look like `$2a$13$ZyprE5MRw2Q3WpNOGZWGbeG7ADUre1Q8QO.uUUtcbqloU0yvzavOm` which does have a structure. The first small bit of data `$2a` is defining what kind of hash algorithm was used. The next portion `$13` defines the *cost*. Cost is about how much power it takes to compute the hash. It is on a logarithmic scale of 2^cost and determines how many times the data is put through the hashing algorithm. For example, at a cost of 10 you are able to hash 10 passwords a second on an average computer, however at a cost of 15 it takes 3 seconds per hash... and to take it further, at a cost of 31 it would take multiple days to complete a hash. A cost of 12 is considered very secure at this time. The last portion of your hash `$ZyprE5MRw2Q3WpNOGZWGbeG7ADUre1Q8QO.uUUtcbqloU0yvzavOm`, looks like one large string of numbers, periods, and letters but it is actually two separate pieces of information. The first 22 characters is the salt in plain text, and the rest is the hashed password!

Das erste kleine Datenbit `$2a` gibt an, welche Art von Hash-Algorithmus verwendet wurde. Der nächste Teil `$13` definiert die *Kosten*. Bei den Kosten geht es darum, wie viel Energie für die Berechnung des Hashwerts benötigt wird. It is on a logarithmic scale of 2^cost and determines how many times the data is put through the hashing algorithm. For example, at a cost of 10 you are able to hash 10 passwords a second on an average computer, however at a cost of 15 it takes 3 seconds per hash... and to take it further, at a cost of 31 it would take multiple days to complete a hash. Ein Aufwand von 12 gilt zur Zeit als sehr sicher. The last portion of your hash `$ZyprE5MRw2Q3WpNOGZWGbeG7ADUre1Q8QO.uUUtcbqloU0yvzavOm`, looks like one large string of numbers, periods, and letters but it is actually two separate pieces of information. The first 22 characters is the salt in plain text, and the rest is the hashed password!

-Time to implement another sorting algorithm. This time, you'll be implementing a <dfn>selection sort</dfn>. Selection sort works by finding the smallest value in the array, then swapping it with the first value in the array. Then, it finds the next smallest value in the array, and swaps it with the second value in the array. It continues iterating through the array until it is completely sorted.
+È tempo di implementare un altro algoritmo di ordinamento. Questa volta, implementerai l'algoritmo <dfn>selection sort</dfn>. Selection sort funziona trovando il valore minimo nell'array e poi scambiandolo con il primo valore dell'array. Quindi, trova il valore più piccolo successivo nell'array, e lo scambia con il secondo valore nell'array. Continua a iterare sull'array fino a quando non è completamente ordinato.

-Combinators allow us to combine multiple selectors differently than either grouping or chaining them, as they show a relationship between the selectors. There are four types of combinators in total, but for right now we’re going to only show you the descendant combinator, which is represented in CSS by a single space between selectors. A descendant combinator will only cause elements that match the last selector to be selected if they also have an ancestor (parent, grandparent, etc) that matches the previous selector.
+Combinadores nos permitem combinar vários seletores de modo diferente do que por agrupamento ou encadeamento, pois mostram uma relação entre os seletores. Existem quatro tipos de combinadores no total, mas, por enquanto, mostraremos apenas o combinador descendente, que é representado no CSS por um espaço único entre seletores. Um combinador de descendente fará com que elementos que coincidam com o último seletor sejam selecionados se também tiverem um ancestral (pai, avô, etc.) que corresponda ao seletor anterior.
 
-So something like `.ancestor .child` would select an element with the class `child` if it has an ancestor with the class `ancestor`. Another way to think of it is child will only be selected if it is nested inside of `ancestor`, no matter how deep. Take a quick look at the example below and see if you can tell which elements would be selected based on the CSS rule provided:
+Então, algo como `.ancestor .child` selecionaria um elemento com a classe `child` se tiver um ancestral com a classe `ancestor`.

-There’s really no limit to how many combinators you can add to a rule, so `.one .two .three .four` would be totally valid. This would just select an element that has a class of `four` if it has an ancestor with a class of `three`, and if that ancestor has its own ancestor with a class of `two`, and so on. You generally want to avoid trying to select elements that need this level of nesting, though, as it can get pretty confusing and long, and it can cause issues when it comes to specificity.
+Não há limite para quantos combinadores você pode adicionar a uma regra, então `.one .two .three .four` seria totalmente válido.

-Okay, you went over quite a bit so far. The only thing left for now is to go over how to add all this CSS to your HTML. There are three methods to do so.
+Tudo bem, você já passou por um bocado até aqui. A única coisa que falta por enquanto é ver como adicionar esse CSS ao HTML. Existem três métodos para fazer isso.
 
-External CSS is the most common method you will come across, and it involves creating a separate file for the CSS and linking it inside of an HTML’s opening and closing `<head>` tags with a self-closing `<link>` element:
+O CSS externo é o método mais comum que você encontrará. Ele envolve a criação de um arquivo separado para o CSS e a vinculação desse arquivo dentro das tags de abertura e fechamento de um elemento `<head>` do HTML na forma de um elemento `<link>` de fechamento próprio:
 
-First, you add a self-closing `<link>` element inside of the opening and closing `<head>` tags of the HTML file. The `href` attribute is the location of the CSS file, either an absolute URL or, what you’ll be utilizing, a URL relative to the location of the HTML file. In the example above, you are assuming both files are located in the same directory. The `rel` attribute is required, and it specifies the relationship between the HTML file and the linked file.
+Primeiro, você adiciona um elemento `<link>` de fechamento próprio dentro das tags de abertura e fechamento de `<head>` do arquivo HTML. O atributo `href` é o local do arquivo CSS, que pode ser um URL absoluto ou um URL relativo à localização do arquivo HTML (você usará essa última opção). No exemplo acima, você está assumindo que ambos os arquivos estão localizados no mesmo diretório. O atributo `rel` é necessário e especifica a relação entre o arquivo HTML e o arquivo vinculado.
 
-Then inside of the newly created `styles.css` file, you have the selector (the `div` and `p`), followed by a pair of opening and closing curly braces, which create a “declaration block”. Finally, you place any declarations inside of the declaration block. `color: white;` is one declaration, with `color` being the property and `white` being the value, and `background-color: black;` is another declaration.
+Então, dentro do arquivo de estilos recém-criado `styles.css`, você tem o seletor (`div` e `p`), seguido por um par de chaves de abertura e de fechamento, que criam um "bloco de declaração". Por fim, colocamos as declarações dentro do bloco da declaração. `color: white;` é uma declaração, com `color` sendo a propriedade e `white` o valor. `background-color: black;` é outra declaração.
 
-A note on file names: `styles.css` is just what you went with as the file name here. You can name the file whatever you want as long as the file type is `.css`, though “style” or “styles” is most commonly used.
+Uma observação sobre os nomes dos arquivos: `styles.css` é simplesmente um nome escolhido como nome do arquivo aqui. Você pode nomear o arquivo como quiser, desde que o tipo de arquivo seja `.css`. No entanto, "style" ou "styles" é o nome mais comumente usado.
 
-A couple of the pros to this method are:
+Algumas das vantagens desse método são:
 
-1. It keeps your HTML and CSS separated, which results in the HTML file being smaller and making things look cleaner.
-2. You only need to edit the CSS in one place, which is especially handy for websites with many pages that all share similar styles.
+1. Ele mantém o HTML e o CSS separados, fazendo com que o arquivo HTML seja menor e mais limpo.

-Internal CSS (or embedded CSS) involves adding the CSS within the HTML file itself instead of creating a completely separate file. With the internal method, you place all the rules inside of a pair of opening and closing `<style>` tags, which are then placed inside of the opening and closing `<head>` tags of your HTML file. Since the styles are being placed directly inside of the `<head>` tags, you no longer need a `<link>` element that the external method requires.
+CSS interno (ou CSS incorporado) envolve adicionar o CSS no próprio arquivo HTML em vez de criar um arquivo completamente separado.

Any inline CSS will override the other two methods, which can cause unexpected results. (While you won’t dive into it here, this can actually be taken advantage of).

-The above is an example of a cryptic kakuro (also known as cross sums, or even sums cross) puzzle, with its final solution on the right. (The common rules of kakuro puzzles can be found easily on numerous internet sites. Other related information can also be currently found at krazydad.com whose author has provided the puzzle data for this challenge.)
+Acima, vemos um exemplo de um quebra-cabeças kakuro críptico (também conhecido como somas cruzadas, ou mesmo um cruzamento de somas), com a sua solução final à direita. As regras comuns dos quebra-cabeças kakuro podem ser encontradas facilmente em vários sites da Internet. Outras informações relacionadas também podem ser encontradas atualmente em krazydad.com, cujo autor forneceu os dados do quebra-cabeça para este desafio.
 
-The `testPuzzles` array contains the description of 200 such puzzles, a mix of 5x5 and 6x6 types. The first puzzle in the file is the above example which is coded as string as follows:
+O array `testPuzzles` contém a descrição de 200 desses quebra-cabeças, uma mistura dos tipos 5x5 e 6x6. O primeiro quebra-cabeças no arquivo é o exemplo acima, que está codificado da seguinte forma:
 
 `6,X,X,(vCC),(vI),X,X,X,(hH),B,O,(vCA),(vJE),X,(hFE,vD),O,O,O,O,(hA),O,I,(hJC,vB),O,O,(hJC),H,O,O,O,X,X,X,(hJE),O,O,X`
 
-The first character is a numerical digit indicating the size of the information grid. It would be either a 6 (for a 5x5 kakuro puzzle) or a 7 (for a 6x6 puzzle) followed by a comma (,). The extra top line and left column are needed to insert information.
+O primeiro caractere é um algarismo que indica o tamanho da grade de informação. Seria um 6 (para um quebra-cabeças de kakuro 5x5) ou um 7 (para um quebra-cabeças 6x6) seguido por uma vírgula (,). A linha acima e a coluna da esquerda adicionais são necessárias para inserir informações.
 
-The content of each cell is then described and followed by a comma, going left to right and starting with the top line.
+O conteúdo de cada célula é então descrito e seguido por uma vírgula, indo para a esquerda para a direita e começando com a linha superior.
 
-`X` = Gray cell, not required to be filled by a digit.
+`X` = Célula cinza, não é necessário ser preenchida por algarismos.
 
-`O` (upper case letter)= White empty cell to be filled by a digit.
+`O` (letra maiúscula) = Célula vazia branca para ser preenchida por um algarismo.
 
-`A` = Or any one of the upper case letters from A to J to be replaced by its equivalent digit in the solved puzzle.
+`A` = Ou qualquer uma das letras maiúsculas de A a J, que será substituída pelo seu algarismo equivalente no quebra-cabeças resolvido.
 
-`( )` = Location of the encrypted sums. Horizontal sums are preceded by a lower case "h" and vertical sums are preceded by a lower case "v". Those are followed by one or two upper case letters depending if the sum is a single digit or double digit one. For double digit sums, the first letter would be for the "tens" and the second one for the "units". When the cell must contain information for both a horizontal and a vertical sum, the first one is always for the horizontal sum and the two are separated by a comma within the same set of brackets, ex.: (hFE,vD). Each set of brackets is also immediately followed by a comma.
+`( )` = Localização das somas criptografadas. Somas horizontais são precedidas por uma letra minúscula "h" e somas verticais são precedidas por uma letra minúscula "v". Essas são seguidas por uma ou duas letras maiúsculas, dependendo de a soma ser de um único algarismo ou de um algarismo duplo. Para somas de dois algarismos, a primeira letra seria a das "dezenas" e a segunda a das "unidades". Quando a célula deve conter informações tanto para uma soma horizontal quanto vertical, o primeiro é sempre para a soma horizontal e os dois são separados por uma vírgula dentro do mesmo conjunto de parênteses, ex. (hFE,vD). Cada conjunto de parênteses é também imediatamente seguido por uma vírgula.
 
-The description of the last cell is followed by a Carriage Return/Line Feed (CRLF) instead of a comma.
+A descrição da última célula é seguida por um Retorno de carro/Feed de Linha (CRLF) em vez de uma vírgula.
 
-The required answer to each puzzle is based on the value of each letter necessary to arrive at the solution and according to the alphabetical order. As indicated under the example puzzle, its answer would be 8426039571. At least 9 out of the 10 encrypting letters are always part of the problem description. When only 9 are given, the missing one must be assigned the remaining digit.
+A resposta necessária para cada quebra-cabeças baseia-se no valor de cada letra necessária para chegar à solução e de acordo com a ordem alfabética. Tal como indicado no quebra-cabeças de exemplo, a resposta seria 8426039571. Pelo menos 9 das 10 letras criptografadas são sempre parte da descrição do problema. Quando apenas 9 são dadas, o número que falta deve ser atribuído à letra restante.
 
-You are given that the sum of the answers for the first 10 puzzles in `testPuzzles` is 64414157580.
+Você é informado de que a soma das respostas dos primeiros 10 quebra-cabeças em `testPuzzles` é 64414157580.
