You're The Best Pilot We Ever Had


"You're the best pilot we ever had". This is from the magical line in the movie where Coop finds the secret NASA station and finds out he is going into space! 👾👾👾👽

I'm quoting Interstellar!

I love that line - it inspires me so much. It inspires me to be really thorough in my learning so that I can be the best possible Software Engineer that I can be.

Back-End Validation 

"No matter how complete the front-end validation of a website or application seems, validations must also be completed on the back-end or server side"

It says that:
  • "Front-end validations are easy to bypass - a malicious user can simply turn off JavaScript on their browser, for example". 
  • There's also a potential for "middleman attacks in which data is changed after the requested is submitted by the user but before it arrives at the server". 
    • Huh what?
      • How does that even WORK?
    • I didn't know that that was even POSSIBLE.
  • "As a rule, THE BACK-END should never trust the data it receives."
I LOVE THIS STUFF.

OMG I LOVE THIS STUFF SO SO MUCH.

OMG I LOVE THIS STUFF.

More Random Messy Notes

On Back-End Validation...

  • "AS THE DEVELOPER, ONCE DATA IS IN THE BACK-END, WE HAVE COMPLETE CONTROL OVER IT,  LUCKLY".
  • BACK-END VALIDATION HAS SEVERAL ADVANTAGES.

There are two main ways to validate inputs on the server-side.

There are two main ways to validate inputs on the server-side.

What are these?

THE FIRST ONE:
  • Takes place while the user is still inputting data into the form on the front-end
  • We can make async requests to the server with pieces of their data
    • And send directly to the user
    • Before they've submitted
  • This is slower than front-end validation
  • It can also be a design challenge from a user-experience perspective
THE SECOND ONE:
  • Is once the form has been submitted
  • Backed-end form validation is: "our application's last defence against problematic data" 
  • And it's essential to verify the validity and safety of our data 
  • Before adding it to a database
  • In this way: 
  • There is also an opportunity:
  • To 'SANITISE' the data
    • In order for our database to be useful:
    • it's important that all data within it is formatted consistently.
  • While we may want to be flexible about the formatting we require from a user, 
    • we likely want to transform inputs into a strict format before entering them in the database.
Do I understand what any of this means? No not really.

Oh wait yes I do - thanks!!!

Life can be so hard. It can be so hard. It can be so, so, so hard. And

In fact it can be so so messy.

But one thing's for sure: I love what I do. 

I love what I do.

I love what I do.

I love what I do.

I know that I love what I do.

Thank you.

Hello World

 Hello from Susanna Codes! Hi everyone,  My name is Susanna and I'm a 28-year-old aspiring software engineer from Brighton! As I type this, listening to music from "Le Fabuleux Destin d'Amelie Poulain" (it reminds me of home, in Luxembourg, where I am from - I'm missing home quite a lot lately!) and look forward to some Irish Cream tea in my afternoon break, I am thinking: How lucky I am that my amazing colleague Rosana helped me out with a plan for my software engineer journey (she directed me to the front-end first). How HTML and CSS would not have been my first languages of choice had I not been guided in this direction, as in my head they were seen as 'less-serious' langages. How done I am with what other people think of me and if other people see the 'front-end' as softer then so be it! Everyone has to start somewhere. I am so grateful to be on this journey, with Codecademy's Front-End Engineer Career Path.  Thank you to Async Brighton as

Yosemite

Yosemite I'll never forget the first time I head the song Yosemite by Lana del Rey. I very nearly clicked away.  It was quite near the start of my Software Engineering journey, right near when I start learning the Front-End/Web Development. I was listening to Arcadia by LDR before, maybe twice, and then Blue Banisters came on. I nearly clicked away in the first 30 seconds but I forced myself to keep listening anyway.  I'll never forget how that song has made me feel. It became my song of 2022 even though I only discovered it in November. I can still listen to it every day and get that complete sense of wonder and of awe that I felt the first time that I heard it. That ending of the song is completely amazing, and it just completely just blows me away every time. "Withstanding all the time, changes, and seasons..." - LDR Concise Body Arrow Functions Why am I so bad at arrow functions? Whyyyyyyyyyyy?  Just kidding, I am beginning to get them. But why are they so hard? &

Two Lines of Thought, Makes Me Wonder What I'm Missing

Two Lines of Thought, Makes Me Wonder What I'm Missing "Lines of Bamboo, See What You Do To Me..." Bamboo by Elder Island is one of my ultimate 'becoming a Software Engineer songs'. (I prefer the original, but here is a great live version. ) There's a story behind this. I met a man named Mark. He was an SWE approaching retirement - he was down in my hometown with his wife, visiting. I won't go into the context of how we met, but it was a miracle. It was a complete miracle. It was just meant to be. We chatted for at least two hours and at the end of the conversation he said to me "All the best of luck with your new career". I couldn't believe what he'd just said - I hadn't even committed to it yet! A few weeks later, I did, though. After I walked out of that cafe where I had been sitting and talking to Mark and his wife though, I felt like - even though I didn't "feel ready" yet - Mark had predicted something that I didn&
