manceraioon Ask HN: Most interesting tech you built for just yourself?

My flatmate used to watch TV in the living room quite loud when I was trying to sleep in my room.

I set a Raspberry Pi with an IR led running an Apache server close to the TV. From my phone I would visit the Raspberry IP and send signals to the IR led to lower the volume.

manceraioon Nikon releases bug fix firmware update for the 10 year-old D7100 DSLR camera

That sounds about right. But how come a manager having a 10 year old camera and not a newest model?

manceraioon Music for Programming

Here is my personal collection of more than 24h of voiceless electronic beats. I know is used for coding by two dev friends and myself:

Enjoy :)

manceraioon Show HN: Responsecodes.xyz

I actually encountered the same issue. I knew there was some service doing that, but I couldn't find it using Google. It took me several minutes.

I guess you have and edge if you manage to match user intent with your keywords and get ranked by Google.

Good luck!

manceraioon Why hasn't Middle Earth had an Industrial Revolution?

Modern science differs from Middle Earth knowledge in having the willingness to admit ignorance. No scientific law, concept, theory or idea is sacred.

I don't think Middle Earth Christianity, Islam or whatever other premodern traditions of knowledge would agree in those two views. Everything that was important to know about the world was already known and written in the Bible, Qur'an or the Vedas.

How on earth there was going to be any secret of the universe yet to be discovered by mere immortals?

manceraioon One year as a solo dev building open-source data tools without funding

It looks like your projects resonate with people, and more important, you are capable of putting them in front of many eyes. Which is even harder than writing code. For that reason, don't seek the validation of VCs and figure out a business around it. Let your customers be your VCs.

Congratulations on your work :)

manceraioon Show HN: SHA-256 explained step-by-step visually

Do you recommend any resources to learn about this?

manceraioon Show HN: SHA-256 explained step-by-step visually

First time doing this type of visualizations. I have this one tailwind.ink which will visualize a color palette on their luminance, chroma and hue values, but it's not really representing the algorithm behind.

manceraioon Show HN: SHA-256 explained step-by-step visually

Thanks :) I first implemented sha256 in js to understand its inner workings. Then I started displaying its variables with react and adding this stepped mechanism. Finally, I added some notes on the left to add some context of what is going on.

It seems like a "nothing up my sleeve" way to initialize the variables.

manceraioon Show HN: SHA-256 explained step-by-step visually

Thanks for the feedback and I am glad you'll use it for teaching (which was the main goal of this project)! The padding part it's briefly explained on the "dynamic" notes on the left column, but yes, can be improved. Typing on the input gives you some sense of what is doing on the background, specially if it jumps to two blocks.

The "for each chunk" is also implemented (which was one of the most difficult parts to synchronize with the UI), but I agree too, I should come up with some way to represent it better. Thanks again :)

manceraioon Show HN: SHA-256 explained step-by-step visually

I actually started this because my first idea was: can I implement SHA-256 with just TTL logic gates? which should be possible, but it would take months to do.

manceraioon New alternatives to HSL and HSV that better match color perception

I created a tool that could help you on creating this type of palettes. It's based on CIELAB and you can see where all the colors are placed in the lightness, chroma and hue space. You can also see they boundaries for any family color so you know how much you can stretch chroma without shifting lightness or hue.
