coding an initial handshake with bitcoin node in rust

Thanks! I'm reading the [rust book (official documentation)](https://doc.rust-lang.org/stable/book/). 

Hi sn,

I've got a js/ts background and I've never really dealt with any low level programming. Thanks to bitcoin, though, I got increasingly interested in its inner workings. I found an amazing resource in [learn me bitcoin](https://learnmeabitcoin.com/) and got inspired by one of its guides about making a network handshake with bitcoin node.

And so, just like that, here I am learning how to work with bytes, endianness, tcp streams. In a rust programming language that I've never used. And all that related to the most exciting piece of technology of my lifetime. 

Never mind, just felt a bit proud to have completed this mini project, learned so much and decided to share. Thanks!

And next? Creating a bitcoin transaction, ofc!

Without doing the math, how long is 50,000 blocks?

hello stackers,

in the past few weeks i've been working on building an expense tracker. why another app of this kind you ask? 

tracking expenses in a commercial app leaks a lot of sensitive information. lofextra differs from other similar apps by storing all the data locally, on your device, where it can't be accessed by any 3rd party. lofextra also supports realtime e2e encrypted sync with other devices you might be using. no registration, no email, no password. just a mnemonic phrase we all know (and love). installable as pwa and works offline as well. fully open source as a bonus. you can read more in the [repository](https://github.com/pycan-jouza/lofextra) or check the [faq](https://lofextra.com/faq)

have a look and let me know what you think. looking forward to your feedback

A must read. Changes your world perception. Most dangerous superstition.

Looking for a technical bitcoin resources

With a background of a fullstack engineer (typescript), I'd like to grasp advanced engineering concepts behind bitcoin workings. In essence, I'd like to be able to understand BIPs and ideally be able to contribute in some way.

Could you recommend some resources? Thanks!

I've built a jukebox on top of lightning

LN Jukebox - direct search feature

The search box debounce is now set to 1 second, should be much better, thanks!

Regarding passing the sats on to artists, how would you go about it?

Thanks for the suggestions! Both are in the todo list :)

No man, it's all people choices, of course!

There sure is! I plan to develop the chat for listeners, but that's a bigger one, so it will take some time.

Hey, me again..

Thanks to @artdesignbySF's suggestion, I've implemented direct search feature so that you don't need to look up audio on youtube and then copy and paste it to the jukebox. Search directly on the jukebox page now!

I know I'm a bit annoying already, but don't worry, no more major feature announcements for at least a week. Minor features are being deployed continuously.

LN Jukebox - performance optimizations + volume adjusting

Hmm, the direct search makes a lot of sense. Thanks for a suggestion!

I've checked your project and it's not exactly how I envisioned the lightning jukebox. That's why I decided to work on mine. I also enjoy the freedom to choose my own tech stack. My implementation brought unique challenges that I wanted to solve. I'm really not trying to be your competition. I might consider joining your project, but as I said before, I wanted to give mine a go first.

Really hard to say. Could be lightning network congestion? From what I've heard, it was always pretty much instant.
