Dance of Shiva


'Dance of Shiva' by Karmacosmic is absolutely one of my favourite songs of all time.

I mean... the joy... contained in there... is just magnificent. It's just magnificent!

Introduction to Form Validation

Websites require a lot of information to function - things like our usernames, our passwords, our 'friends/followers/connections', 'likes', credit card information, and so on.

These all have to be filled out by users on the front-end (or provided). 

User information is traditionally collected using HTML "forms". "If you ever entered text in a website, selected options on a list, or checked a box and then hit enter (/pressed button), YOU LIKELY FILLED OUT AND SUBMITTED AN HTML FORM!!!!". 

Wow.

"The process of checking that the information submitted through a form adheres to expectations is called form validation".

Why Validate Forms?

Most data once submitted into forms is stored by a website or a web app. 
It's stored 'in a database, on the server side'.

There are reasons why it is important for us to make sure that this data is accurate:
  • We want operations that depend on the data to work:
    • E.g. the user's email address needs to be accurate for further communications to go ahead
    • E.g. or the usernames need to be unique or else it will cause errors
  • We want to keep our site secure:
    • "Unprotected data leaves entry points for malicious actors to hurt our application or our users".
      • "Allowing a user to submit a non-secure password means that their account will not be protected.".
      • "Unprotected forms can also allows bits of code to be injected into our servers. This can potentially leave our users' sensitive information exposed.".

Regular Expressions

"Data submitted through forms are stored as strings".

Then it talks about using regular expressions or regex or regexp - eek this is all sooo scary - WHYYYYY!

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? ...

Where To Hide A Star

Where To Hide A Star I haven’t read this book but I just saw this title of a forthcoming children’s book on the train and so I wanted to write a blog post based off of this as well. The last six months have been… rewarding and fulfilling. I have managed to make all of my dreams come true and to defy expectations,  Sometimes the best place to hide is in plain sight and if you reread all of my blogs over the last six months (all 200 of them) you would know exactly what I’m struggling at work and what was going on. And why. But I’ve managed to overcome most of my challenges. Neurodiversity. Being very new in the field relative to the expectations of the job. Being in a new workplace environment. All stuff which I can handle and I am doing just fine. Because I am amazing and fabulous and I can do anything. I am loving the job. I am thriving. I am loving just getting on with it. I love my work. I am having massive breakthroughs. On Thursday I had what felt like the biggest breakthrough ...
