💲 How much is a website ??

Youssef Rabei — Sat, 01 Aug 2020 16:33:07 +0000

TL;DR I Want to know how to estimate a price for my websites from simple HTML sites to Complex sites (blog, e-commerce, etc...)

This is my first paid website.
It's still finishing it (so be gentle).

What I used to build it

For the Front-End I used React
For the CMS I used Contentful
For the Hosting I used Netlify
For the Analytics I used Google Analytics

What are the Pages/Features (It's a simple website)

The Main Home page (dah)
A Gallary with up to 25,000 images (Updateable using Contentful)
A 3D CV page with up to 25,000 (minus the above images) (Updateable using Contentful)
A Static About page
And it's responsive (Like if there is a 2020 web isn't)
404 Page (Work in progress)

I will add in the future

A detailed page for every image in the gallery (and probably I will host the images separately with Cloudinary)
simple profile so users can comment on the images and rate it and like it etc...
Blog using Contentful

So how much should this website now and after the new features cost

And how to estimate my future website or my old personal websites

I searched online and found a couple of blog posts BUT I think it was super expensive
And I found these websites that ask some questions like how many pages does it have cms or a blog and how is the design, etc... and then give you a price and I liked it but I didn't believe it that I can make websites that value these numbers
I will be so happy if these numbers were true because I'm 16 and I can have these numbers
I always loved programming not because of the money I can make I didn't even know how much until now I loved it because the creativity and the problem solving and all this fun stuff not money so that is why I'm a little surprised

Multiples of 3 or 5 : ✍ by jhoffner

📃 Description

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

🤔 Thinking

I'm gonna make a for loop will check if a number less than the limit divisible % by 3 or || 5
Then push it to an array
Then add it

👨‍💻 Code

const solution = num => {
  let divBy3Or5 = [];

  for(let i = 1; i < num; i++) {
    ((i % 3 === 0) || (i % 5 === 0)) ? divBy3Or5.push(i) : null;  
  }

  return divBy3Or5.reduce((acc, elm) => acc + elm, 0);
}

I think it's a stupid code like it has to be a better way to solve this kata

Validate Credit Card Number : ✍ by mcclaskc

📃 Description

In this Kata, you will implement the Luhn Algorithm, which is used to help validate credit card numbers.
Given a positive integer of up to 16 digits, return true if it is a valid credit card number, and false if it is not.

Here is the algorithm:

Double every other digit, scanning from right to left, starting from the second digit (from the right).
Another way to think about it is: if there are an even number of digits, double every other digit starting with the first; if there are an odd number of digits, double every other digit starting with the second:

1714 ==> [1*, 7, 1*, 4] ==> [2, 7, 2, 4]

12345 ==> [1, 2*, 3, 4*, 5] ==> [1, 4, 3, 8, 5]

891 ==> [8, 9*, 1] ==> [8, 18, 1]

If a resulting number is greater than 9, replace it with the sum of its own digits (which is the same as subtracting 9 from it):

[8, 18*, 1] ==> [8, (1+8), 1] ==> [8, 9, 1]

// OR

[8, 18*, 1] ==> [8, (18-9), 1] ==> [8, 9, 1]

Sum all of the final digits:

[8, 9, 1] ==> 8 + 9 + 1 = 18

Finally, take that sum and divide it by 10. If the remainder equals zero, the original credit card number is valid.

18 (modulus) 10 ==> 8 , which is not equal to 0, so this is not a valid credit card number

🤔 Thinking

I will create an array out of the credit card number
Then check its length if it's even I will loop over it starting in the first index 0 jumping one index at a time like 0, 2, 4, 6, n.length if its odd I will do the same but starting in the second element index number 1
Then double it and add them into another array and then sum it
Then divide it by 10 and check if its remainder is equal to 0

👨‍💻 Code

const validate = num => {
  let numArr = Array.from(String(num), Number);

  if (numArr.length % 2 === 0) {
    for(let i = 0; i< numArr.length; i+=2) {
      numArr[i] *= 2;
    }
  } else {
    for(let i = 1; i< numArr.length; i+=2) {
      numArr[i] *= 2;
    }
  }

  const lessThan18Arr = numArr.map(num => num > 9 ? num - 9 : num)

  const sum = lessThan18Arr.reduce((acc, elm) => acc + elm, 0)

  return sum % 10 === 0;
}

🐞 Bugs

I think it's the Time complexity (Both Solutions takes about 1000ms give or take 100ms)
And there is repetitive code
Not DRY (Don't Repeat Yourself)

🏁 Finally

const validate = num => {
  let numArr = Array.from(String(num), Number);  
  let i = numArr.length % 2 === 0 ? 0 : 1; 

  while(i < numArr.length) {
    numArr[i] *= 2;
    i+=2;
  }

  const lessThan18Arr = numArr.map(num => num > 9 ? num - 9 : num)

  const sum = lessThan18Arr.reduce((acc, elm) => acc + elm, 0)

  return sum % 10 === 0;
}

Testing 1-2-3 : ✍ by acr

📃 Description

Write a function which takes a list of strings and returns each line prepended by the correct number.

Examples:

number([]) // => []
number(["a", "b", "c"]) // => ["1: a", "2: b", "3: c"]

🤔 Thinking

map over the array and return an array using template literal every element with its index

👨‍💻 Code

const number = arr => arr.map((elm, i) => `${i+1}: ${elm}`)

Stop gninnipS My sdroW! : ✍ by xDranik

📃 Description

Write a function that takes in a string of one or more words, and returns the same string, but with all five or more letter words reversed (Just like the name of this Kata). Strings passed in will consist of only letters and spaces. Spaces will be included only when more than one word is present.

Examples:

spinWords( "Hey fellow warriors" ) // => "Hey wollef sroirraw"
spinWords( "This is a test") // =>"This is a test"
spinWords( "This is another test" ) // =>"This is rehtona test"

🤔 Thinking

Turn the string into an array of words (strings)
Then Check if the word length >= 5
If true I will reverse the word(s)
Then join it all

👨‍💻 Code

const spinWords = str => {
  const arr = str.split(" ");
  const spinedarr = arr.map(word => {
   return word.length >= 5 ? word.split("").reverse().join("") : word;
  })

  return spinedarr.join(" ");
}

Credit Card Mask : ✍ by samranjbari

📃 Description

Write a function maskify, which changes all but the last four characters into '#'.

Examples:

maskify("4556364607935616") // => "############5616"
maskify(     "64607935616") // =>      "#######5616"
maskify(               "1") // =>               "1"

🤔 Thinking

I'm will make an array and then slice it so I get the last 4 digits
Then use the padStart method to create a string with the same length with that starts with #s

🤷‍♂️ What?

MDN:

The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.

👨‍💻 Code

const maskify = cc => {
  const last4 = cc.split("").slice(-4);

  const masked = cc.length >= 4 ? last4.join("").padStart(cc.length, "#") : cc;

  return masked
}

Sort array by string length: ✍ by Steve hopkinson

📃 Description

Write a function that takes an array of strings as an argument and returns a sorted array according to the string length Ascendingly

🤔 Thinking

I didn't have to think that much.
I know how sort works it takes a compare function or two arguments the first is the first element and the second is the second element and it keeps increment the index like the map or the filter methods

👨‍💻 Code

const sortByLength = arr => arr.sort((x, y) => x.length - y.length);

Descending Order : ✍ by TastyOs

📃 Description

make a function that can take any non-negative integer as an argument and return it with its digits in descending order. Essentially, rearrange the digits to create the highest possible number.

🤔 Thinking

It's pretty much like the last one
I will make the number an array then sort it then make it a number again It's easy

👨‍💻 Code

const descendingOrder = num => {
  const digitArr = Array.from(String(num), Number);
  const sortedArr = digitArr.sort((x, y) => y - x);
  const sorted = Number(sortedArr.join(""));

  return sorted;
}

Playing with digits : ✍ by g964

📃 Description

Given a positive integer n written as abcd... (a, b, c, d... being digits) and a positive integer p

we want to find a positive integer k, if it exists, such as the sum of the digits of n taken to the successive powers of p is equal to k * n. #### In other words: Is there an integer k such as : (a ^ p + b ^ (p+1) + c ^(p+2) + d ^ (p+3) + ...) = n * k If it is the case we will return k, if not return -1.

🤔 Thinking

I will make the first number n an array, like in the last kata.
Then I will map over it and power it with p + index index is the second argument in the map method.
Then Add it all.
Then check if it's equal to n * k

👨‍💻 Code

const digPow = (n, p) => {
  const k = n * p;
  const numArr = Array.from(String(n), Number);
  const sum = numArr.reduce((acc, elm, i) => (elm ** (p + i)) + acc);  
  const result = sum === k ? p : -1;

  return result
}

🐞 Bugs

I don't understand what he want from this description

🏁 Finally

After many times trying and trying and reading the discussion section I gave up and googled it but I said to myself if I keep doing that I will never be better and I won't be better, So I didn't look at the solutions and reminded myself that I don't have to cheat so when I write this post it will be bugless

If I didn't have any bugs, I didn't learn anything new

So I unlocked the solutions and looked at them and then I submit this

const digPow = (n, p) => {
  const numArr = Array.from(String(n), Number);
  const sum = numArr.reduce((acc, elm, i) => acc + (elm ** (p + i)), 0);  
  const result = sum === (n * p) ? p : -1;

  return sum % n ? -1 : sum / n;
}

Sorry for the similar katas, But I will take it as today was my num to arr / sort day

I wasn't thinking right at first.

I wanted to make an array with the end of the given string and then compare it to the given ending by pushing end length times

👨‍💻 Code

const solution = (str, ending) => {
  const arr = str.split("");
  let endingL = 0;
  let endingArr = [];

  while(endingL < ending.length) {
    endingArr.push(arr.pop());
    endingL += 1;
  }

  let endingStr = endingArr.reverse().join("");

  return ending === endingStr ? true : false;
}

🐞 Bugs

I think it's the time complexity
Too much code for a simple task

🏁 Finally

Right After submitting my answer, my internet connection lost and I didn't even have the chance to read other people solutions, So I had the time to laugh on myself and see how stupid I was 🤣, And I remembered the substr method

So after the internet is back I submited this code

const solution = (str, end) => str.substr(str.length-end.length) === end;

Does my number look big in this? : ✍ by JulianNicholls

📃 Description

A Narcissistic Number is a number which is the sum of its own digits, each raised to the power of the number of digits in a given base. In this Kata, we will restrict ourselves to decimal (base 10).

🤔 Thinking

I have to turn the number into an array so I can map over it and power every digit with number length and then add it with the reduce method and then check if it's equal to the original number

I removed the map and made it all with the reduce

👨‍💻 Code

const narcissistic = num => {
  const arrOfDigits = Array.from(String(num), Number);
  const pow = arrOfDigits.length;

  const sum = arrOfDigits.reduce((acc, val) => val ** pow + acc, 0 )

  return sum === num;

Javascript saves the world

Youssef Rabei — Tue, 14 Apr 2020 21:16:54 +0000

When building apps, we focus on minimizing costs, time to market, bugs, bundle size, application speed, SEO, but we spend almost no effort trying to minimize the damage our applications are making to the environment.

Global-Warming

So Carbon dioxide (CO2) is a greenhouse gas that gets pumped to the atmosphere and acts like a blanket that traps heat.
There is also Methane (CH4) it has 25 times the heating potential of Carbon dioxide.

What is CO2e (Carbon Dioxide Equivalent)

It's 1 ton of Methane, 25 tons of Carbons + some other gases.

Google says it's

The standard unit for measuring carbon footprints. The idea is to express the impact of each different greenhouse gas in terms of the amount of CO2 that would create the same amount of warming.

There was a Paris Climate agreement in 2016 where 187 states agreed on trying to keep the increase in temperature to 2 degrees or ideally 1.5 degrees (We already reached 1 degree)

No one cares about 2 degrees We don't even feel it.
Let me tell you that there are species will extinct if this happened

A report from the UN says that is likely we hit 3.2C by the end of the century

What happens when the climate rise 5°C

All water ice on the planet will meltdown, raising the sea levels a few dozen meters above the normal “sea levels” and destroying the coastlines, and it will be a catastrophic event obviously, and millions upon millions of animal species (discovered and Undiscovered) will die.

We need to start reducing the climate rise curve

As a Developer you have an impact (A big one too)

Electricity is responsible for 30% of the CO2e.
80% of the world's electricity is created from burning Fossil fuels.
So don't waste electricity, because we destroying our planet to create some electricity so don't wast it.

Microsoft Azure and Google Cloud are Carbon-neutral firms.

Carbon neutral: A product or company that's carbon neutral (or carbon-free) is removing the same amount of carbon dioxide it's emitting into the atmosphere to achieve net-zero carbon emissions, usually by purchasing carbon offsets or credits to make up the difference.

Servers "Carbon" Cost

(The carbon released to create the electricity to run the server)
Let's talk about an absolute Dell server

To run a server

It's about 600 kilograms of carbons that are the electrical cost of it was running at 100% for a year

Idle server

Still costs electricity even nothing running on it, still cost about 25% or 150 kilograms of carbon a year

To create the server

If we said we created that particular server and got four yeara lifespan it produced 320 kilograms of carbon

So idle servers waste almost half a ton of CO2e per year (creation + idleness)

What the hell is serverless?

It's an execution model where the cloud provider (AWS, Azure, or Google Cloud) is responsible for executing a piece of code by dynamically allocating the resources. And only charging for the amount of resources used to run the code.

How serverless help

So when you use something like Microsoft Asure, Google Cloud or AWS your code gets executed next to my code, So we utilize all the servers at 100%, So no waste.

Serverless is greener because

CO2e was released to create the server
CO2e was released to power the server
If you don't run 100% of your server you are wasting CO2e

serverless run servers at 100%

How to go Serverless in Node.js?

We have

Microsoft Azure Function
AWS Lambda Function
Google Cloud Function

So there is a problem when you use azure function you got this

module.exports = async function(context, req) {
  context.log("Javascript HTTP trigger function processed a request.");

  if (req.query.name || (req.body && req.body.name)) {
    context.res = {
      // status: 200, /* Defaults to 200 */
      body: "Hello " + (req.query.name || req.body.name)
    };
  } else {
    context.res = {
      status: 400,
      body: "Please pass a name on the query string or in the request body"
    };
  }
};

So we gonna use nestjs

with Microsoft Azure

nest add @nestjs/azure-func-http

Basically, it adds or updates 10 files into your nest project to serverless application
And when you want to deploy (I recommend to) use a tool named Hexa

npm install -g @manekinekko/hexa
hexa init
hexa deploy

And you are good to go

To know more about nestjs with

Microsoft Azure: go to Nitr.ooo
Google Clouds: See this video
AWS Lambda: Read this article

I'm gonna write about serverless and nodejs again but tech-wise only, with AWS, Google and Azure

I got electrocuted ⚡

Youssef Rabei — Mon, 06 Apr 2020 13:57:28 +0000

So I literally got electrocuted this week that's why I wasn't active this week like I promised and I didn't work on anything.

so what happened

Before

It was 3 am and I was writing (finishing) my second post here on Dev.to

Article No Longer Available

And my little sister Habiba was sitting on the balcony and keep asking me to get her the charger and I kept telling her I will as soon as I finish what I'm doing.

The Spark

So after I posted it I go to show it to her. THEN I got her the charger, plugged it on thas plug that my father created out of the balcony lamp, then the plug fell and I didn't touch it except when Habiba told me that it's not charging so I hold it and I saw that one of the two wires was cut after it fell, So I left it carefully and I told her that I will fix tomorrow, So I got to the room to turn the lights off so no one gets hurt and I was going to isolate it anyway.

Now I'm in it, I'm electrocuting

On my way to turn the lights off SUDDENLY I stopped in the middle of the way (Still don't know why???) I got back to the balcony and touched the naked wire with my left hand and I kept screaming and screaming (involuntarily) like never before and I got pushed to the opposite wall and I keep feeling the heat on my arm and my legs just stopped so I leaned on a (metal) column and I'm still screaming and waving with my hand with the plug that had no intention to leave my hand then Habiba wanted to touch me but thank god I screamed don't touch me and the neighbors got out to there balcony and my mom wakes up freighted and while she was getting a wooden bloom! Thank God I pushed the wire with my right hand and it finished finally or that what I thought.

After

I kept saying that I'm okay so mom doesn't freak out more so as soon I could walk they made me lay on the bed and tried to calm me down, then see if I'm okay, and my right side keeps hurting me.

See what happened to my body

First, check what is going on with my (waist) it's a slight burn and I was shaking then my elbow hurts its another burn but this one is bad I think that where the electricity came out from so I thought it's okay and I told Habiba just like the flash his electricity came out from his feet mine came out from my elbow (I don't know why but I think it's like a mechanism to calm everyone down since it's just me, mom and my little sister were there) and after I started to feel my left hand or the whole side I sat there was a lot of burns (like bubbles) on my palm then I kept crying involuntarily (I think it's because I could have been dead right now on the same day I was telling mom about what I wasn't to do on this year and some of my goals)

Asking doctors on 4 am

Mom posted on Facebook what happened and a lot of them scared us more than I did, but most of them said to go to the nearest hospital (like right now) but I didn't want to go or I didn't want to go like 4 am to a hospital (we are not in my city, we thought since there is lockdown all over Egypt, we go to Alexandria (the place we usually go in holidays and summer break) and my dad wasn't there that week), So some doctors ask to see how the burns look like and they said it's okay to rest for a couple of hours and then go to a hospital just to make sure that the electricity didn't miss any of my systems and while mom was doing that, I prayed but while I'm praying there was a lot of things I forgot and I keep trying to remember but I can't (I'm afraid that it could miss my brain and I will be stupid or something). So mom called dad to come as fast as he can so since there is a lockdown the only train is at 6 am that arrives Alexandria at 9 am so I slept until he came.

Not just electricity it's coronavirus

So after dad came we go to a hospital and they said only one can enter with me (I didn't know why the guards were so intense) so one of the doctors made this thing I don't know what does it called to see my heartbeat and some other things and he said that if there is any damage or something bad my heart wouldn't be normal.
After we got out and told dad that I was okay he heard that one of the laboratory scientists got COVID-19 (so this is why they are so intense).

Finally

Let's just say that I'm so grateful to be alive so thank god

What I'm doing in this WEIRD times?

Youssef Rabei — Thu, 02 Apr 2020 01:25:35 +0000

I'm working on a web app about COVID-19 called COVEGY.
It should have like a dashboard or analytics, the latest news about the coronavirus worldwide, a story about this virus and how to protect ourselves from it, etc.

What technologies I'm using (For Now)

Front-End

For creating the UI I will choose ReactJs and gonna use it's boilerplate create-react-app by Facebook.
For the Styling, I always style using CSS but now I will try Sass

Visualizing my data

Chart.js for displaying the charts obviously
Leaflet for displaying the Map, It's an open-source JavaScript library for mobile-friendly interactive maps

Deployment

I 'm gonna use Netlify, It's free, easy to use and most importantly Fast.

Where to get the data for the dashboard

There is a lot of sources out there but I will choose this API coronatracker

Obstacles (Bugs)

I never made a website that content had to be connected on multiple pages, I made a lot of multi-pages websites like the home page, the about page and so on but now in this web and in my blog I have to divide the news or posts into multiple pages like every page have 5 posts, so I read about it and found that I will make the URL take a parameter I think (I don't remember what does it call exactly) but it will be after the URL "?" a question mark with the page number something like this (www.covegy.netlify.com/news?page=3) OR like this (www.covegy.netlify.com/news/page/3), SO if anyone knows what should I do please let me know in the comments. (Just to know, I'm using react-router)
The Design I'm not a designer and I don't want my design to be normal, So I opened a lot of design websites and I knew what I want to my web be like but when I opened adobeXD I couldn't do it so I made a simple design. So that's it for now, if you have any ideas or questions about this web let me know in the comments

Thanks for reading, I really appreciate it

So I'm gonna write here because I want when I become successful, people will want to know my story (I don't mean fame) or someone like me see my blog and inspires him/her like I saw some blogs that inspired me like Florin Pop who inspired me the most (gonna talk about that topic later).
So basically I want to document every step in my way of becoming what I want to be in programming (in life, and in business).
