If I'm validating a user input form should I use a hash or a encrypted string. I hope to include the user IP, header requested time plus a random number for the string.

So after my hosting my first project and announcing it on devrant, the users pointed out the many security faults and places where the code can be exploited ( thank you so much ). So I started my research on security ( im 99% self-taught ). The first thing I landed across is the code vulnerabilities which the I can fix then the vulnerabilities of the language itself and then binary code to overrun whatever the language it is. Well, the topic gets broader and broader. If I click on a link named xxx vulnerabilities oh god that is a whole new collection of hundeds of wiki like pages. I feel like I'm lost and here I need some real help

Me : I should start building user authentication system.
inner self : there are enough free and secure ones out there, just go read the documentation.
Me : fuck I'm not reading 10000 pages of documentation written in alien language.
inner self : well then you better start building
Me : **writes code
Inner self : you better add the data validation and security while coding
Me : I just want it to work !
Me after a few days trying not to suicide : the site is hacked, the code is bugged, hello darkness my friend

Trying to put together all the code of my ajax request into a function so I do not repeat myself. The code works perfectly outside but not in the function. Well fuck JavaScript. I've been stuck here for two days.

The 1080ti is rated at a little more over 11 teraflops. GPUs with over 1 teraflops of compute performance was released in the early 2000's.
It's 2017 and we are stuck with fancy gen xxx cpus.
I smell a huge compute performance wastage.

After my previous PC bursting into flames when I changed my input voltage to 120v on the power supply my dad never bought me one again this happened when I was aged 12. I was so much in love with computers that I would visit my friends who had ones at home and not leave till their moms asks me to. I remember collecting my lunch money and buying a Pentium 4 mb for dog cheap at a local store and as soon as I plugged in the mb short-circuited and died (I had the other parts as I was scavenging the junk yard for them). I'll never forget the moment I burst into tears seeing my hopes for a PC dieing. So after all the years passing when I was 16 I spent my whole summer vacation working in a construction site doing so much heavy work. There were days that my body couldn't bear and I just fell but somehow by the end of that summer I managed to collect enough money to assemble this 3rd gen dual-core. This is my baby. I'm using it till this date.

Currently I'm learning PHP,java and JavaScript along with the basic web designing. I'm stuck in a point where I can't focus on one language and learn deep into it because my everyday work comes along with a little bit of everything.

When you begin with searching for ajax PHP requests and end up with this

I fucking love my local phone service provider. They have a game (70mb) like Temple run where we get free mobile data for playing it. The 70 mb for downloading it gets reimbursed too !!

I feel so lonely

Got banned from stack overflow because my questions were too "simple". FML. Being a newbie sucks

This happened before I got into web development.
One day me and my best friend (already a developer) was try to download some pirated software on the internet. We found a website which allowed us to download the software but after completing a survey. We completed it but then we landed on another one and this guy sitting next to me took my laptop and deleted the survey pop-up doing something with the chrome developer tools. I was really freaked out and then he told me that is normal and left myself wondering.
