Show HN: 100.st – Dev utilities I built for format conversions and encoding

rjh29 · 2025-05-07T21:15:58 1746652558

This is just AI slop. https://100.st/tools/uuid-nil-generator this generator literally just makes an arbitrary number of identical all-zero UUIDs. Then 10 pages of genAI SEO crap after.

Did a human even pass their eyes over this? Why should I trust anything it does?

i ro know what do u mean, uuid nil is basically all ZEROS. the text below each tool just for SEO not for human to read. I assume a developer knows what is a UUID, base64....

I did something similar but with focus on auto-detections and in-browser only: https://wt.tools/tools

Neat.

OC and you just reminded me of Unicode normalization. I've not needed anything in my own work. Might be useful for others.

Another random notion: Validate UUIDs? Like identify its kind, verify its well formed?

bh213 · 2025-05-08T07:21:52 1746688912

It does validate UUID and detects a few versions (I'd have to check which npm package is used for UUID ) but just copy one into input and it should be validated.

The text column is very thin on pages like the IPv6 address generator. The spacing between the lines also seems too high (reminds me of school essays where for some reason you always had to put tons of space between lines). Maybe consider decreasing the space a little bit for readability.

> for some reason

It's so you/the teacher have room to leave comments/corrections.

i also have my own personal toolset when i need https://tools.woz.lt/

cmd+k is the key

Looks like a fork of: https://github.com/CorentinTh/it-tools

What makes yours better?

putna · 2025-05-07T20:07:57 1746648477

it is, it has a link to repo you mentioned. I would say that having your own instance of these tools, gives some confidence when using tools like Passphrase Generator or bcrypt

ThinkBeat · 2025-05-08T01:09:09 1746666549

That is impressive. I love it.

I wish it came as an offline application.

thats more beautiful and sick modern UI

dadro · 2025-05-07T19:37:47 1746646667

Looks great. Image/file > Base64 and the inverse could be a useful addition.

mqus · 2025-05-07T20:46:08 1746650768

even just text > base64 would also be great

abdelbkk · 2025-05-09T20:00:30 1746820830

Looks like https://gchq.github.io/CyberChef/ except that you can use CyberChef offline. Why reinvent the wheel all the time?

jasonlotito · 2025-05-07T18:21:07 1746642067

> Why reinvent the wheel all the time?

Because since the invention of the wheel, there have been a LOT of changes and inventions that have dramatically improved the wheel.

omneity · 2025-05-07T17:52:24 1746640344

Well it can be a good learning experience for OP, that's reason enough. By the way, I use CyberChef occasionally and I love it, strongly recommended!

bee_rider · 2025-05-07T16:58:58 1746637138

You have a typo I think, “generatw IPv6.”
