For the first time ever, I am launching a product I could easily devote the next ten years of my life to. It honestly feels amazing

I love what it stands for and what it represents, it& #39;s called "Epilepsy Blocker"
It took two months all-day coding to build, thread belowhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="👇" title="Down pointing backhand index" aria-label="Emoji: Down pointing backhand index">

I built a chrome extension that automatically blocks flashing GIFs that may cause an epileptic seizure to people with photosensitive epilepsy, kinda like an AdBlockerhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🛑" title="Stop sign" aria-label="Emoji: Stop sign">

I remember reading articles online about how people with photosensitive epilepsy are having seizures from media content
Things that can make content dangerous:
https://abs.twimg.com/emoji/v2/... draggable="false" alt="💥" title="Collision symbol" aria-label="Emoji: Collision symbol"> Flashing
https://abs.twimg.com/emoji/v2/... draggable="false" alt="🔴" title="Red circle" aria-label="Emoji: Red circle"> Transitions involving red colors

I started building it in the "24hr startup challenge", but it was far more difficult than I expected
Even after the challenge and one month in, I quit because I thought it was not feasible. I wanted to analyze GIFs in real time but the it was taking about four minutes per GIFhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🐌" title="Snail" aria-label="Emoji: Snail">

After that, luckily, I stumbled upon one of @andreyazimov ’s articles, where he talked about going through a similar phase with & #39;MacBook Alarm& #39;. Eventually, he pushed through and managed to finish the project
That inspired me, so I decided to give it another gohttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🌥️" title="Sun behind large cloud" aria-label="Emoji: Sun behind large cloud">

I started studying about photosensitive epilepsy in depth https://abs.twimg.com/emoji/v2/... draggable="false" alt="📚" title="Books" aria-label="Emoji: Books">
What I found was that the UK is the leader in this field, having the most established scientists in the field and the strictest guidelines for TV broadcastinghttps://abs.twimg.com/emoji/v2/... draggable="false" alt="📺" title="Television" aria-label="Emoji: Television">
This where I found established guidelines and papers

I started reading numerous scientific papers and studied linear algebra for the first time after Uni https://abs.twimg.com/emoji/v2/... draggable="false" alt="🎓" title="Graduation cap" aria-label="Emoji: Graduation cap">
By using Python, linear algebra and optimized Python packages written in C, I managed to speed up analysis from four minutes per GIF to just under one second!https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤯" title="Exploding head" aria-label="Emoji: Exploding head">
By using Python, linear algebra and optimized Python packages written in C, I managed to speed up analysis from four minutes per GIF to just under one second!
Initially, I was looping through every single pixel of the GIF, which is time consuming https://abs.twimg.com/emoji/v2/... draggable="false" alt="⌚️" title="Wristwatch" aria-label="Emoji: Wristwatch">
Food for thoughthttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🧠" title="Brain" aria-label="Emoji: Brain">
Imagine a simple GIF, 600x600 pixels with 200 frames. That makes for 600x600 pixels x 200 frames = 72 million pixels to analyze, crazy

The way I managed to overcome this was by:
Specialized algorithmhttps://abs.twimg.com/emoji/v2/... draggable="false" alt="👨🔬" title="Man scientist" aria-label="Emoji: Man scientist">
Switching to Python and Python packages written in optimized C code and using specific matrix functionshttps://abs.twimg.com/emoji/v2/... draggable="false" alt="🐍" title="Snake" aria-label="Emoji: Snake">
I will write a large blog post sometime in the future where I will write all the details

So far I had launched Epilepsy Blocker on Reddit but was taken down very quickly due to "self promotion"
However, while it was still up, someone subscribed for $10/mohttps://abs.twimg.com/emoji/v2/... draggable="false" alt="💳" title="Credit card" aria-label="Emoji: Credit card">
That means that Epilepsy Blocker is officially helping someone stay safe onlinehttps://abs.twimg.com/emoji/v2/... draggable="false" alt="💙" title="Blue heart" aria-label="Emoji: Blue heart">
