hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

Background and Cron Jobs

This worked on 14/May/23. The instructions will probably require updating in the future.

llama is a text prediction model similar to GPT-2, and the version of GPT-3 that has not been fine tuned yet. It is also possible to run fine tuned versions (like alpaca or vicuna with this. I think. Those versions are more focused on answering questions)

Note: I have been told that this does not support multiple GPUs. It can only use a single GPU.

It is possible to run LLama 13B with a 6GB graphics card now! (e.g. a RTX 2060). Thanks to the amazing work involved in llama.cpp. The latest change is CUDA/cuBLAS which allows you pick an arbitrary number of the transformer layers to be run on the GPU. This is perfect for low VRAM.

Clone llama.cpp from git, I am on commit 08737ef720f0510c7ec2aa84d7f70c691073c35d.

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

	print("====")
	print("".join(map(lambda i: ([""]9+["\n"])[(i>>1)%10] if i&1 else "" if (i>>1)//10 in (0, 9, (i>>1)%10, 9-((i>>1)%10)) else " ", range(200))))

	commentWrapper.style.marginLeft = '10px';
	commentWrapper.style.color = '#333';

	I was drawn to programming, science, technology and science fiction
	ever since I was a little kid. I can't say it's because I wanted to
	make the world a better place. Not really. I was simply drawn to it
	because I was drawn to it. Writing programs was fun. Figuring out how
	nature works was fascinating. Science fiction felt like a grand
	adventure.

	Then I started a software company and poured every ounce of energy
	into it. It failed. That hurt, but that part is ok. I made a lot of
	mistakes and learned from them. This experience made me much, much
