In transaction model (in Explorer API) we have address as input instead of txId with index. Is there any way to check tx output spending?

Generally, my question is how to check the particular UTXO status using cardano sl API?

When can everyone stake ADA? I was not involved with the snapshot.

Hi! We use Cardano in our exchange service, currently our node uses version 1.3.2 and we plan to upgrade it to 3.2.0.What API version will be most suitable for 3.2.0? The latest docs I found are 1.7.0 versioned.And as I see, API v0 will be deprecated soon, so all the endpoints we use right now will not work and we should move to v1 fully?

In March, Charles Hoskinson is supposed to tell an exact date for the start of Shelley mainnet.

is the absence of an x86_64-unknown-linux-gnu build for 0.8.10 intentional?

Hi! Any advice on ways to introduce my teenager into learning how to be a programmer? I know Haskell requires an advanced skillset, looking for suggestions for him to get there?Thanks

Haskell has successfully been taught to high school kids

it doesn't actually require an advanced skillset - in fact for someone starting from scratch it won't be any different to learning any other language

the reputation it has for being hard to learn has a lot to do with it being very different from more popular languages in the industry and there are a lot of things people have to unlearn when getting used to Haskell

I'd look at what they're interested in first, then decide on which angle to push for to get them interested - someone who is only interested in games and visual stimulus may require a different approach to someone who is intrigued by puzzles

so if you want them learning Haskell, you may have to look at some related languages like Elm where it's easier to get a graphical app or a game going - otherwise can start with learnyouahaskell and go from there, though if they haven't done any programming before you will have to clarify things and help them out, probably work with them, which you'd have to do anyway really

Is there already a specific Plutus guide, any recommended books or other sources?What would be a good starting point in order to learn Plutus? Does it require learning Haskell first?

I think learning Haskell first would give you a very good starting point

having said that I haven't looked at Plutus aside from skimming some of the docs on the IOHK website

Great, thanks a lot for your reply!If somebody knows a very good Plutus learning resource, please tell. :)

I don't think you'll find much more than what's on the IOHK website at the moment - I heard something about someone having written a book but I'd be hesitant to get one just yet seeing how all of this is still work in progress

https://cardanodocs.com/technical/plutus/introduction/ <— what's here looks syntactically a lot like Haskell - not identical but very similar

so getting the hang of Haskell or one of the ML (Caml, F#, Standard ML) derivatives would definitely be a good first step - Haskell probably more so to get used to being largely forced to write immutable code

in ML land it's easier to find ways to avoid that

and aside from Haskell, you could have a look at the other smart contract languages - more in the sense of what they're capable of or what they're used for

To prepare for Plutus at this time, getting very comfortable with Haskell basics is the best return on time, in my opinion.

There is an official Plutus eBook on Amazon, and a course on Udemy. I own both.

They are nice to give context.

Search Amazon for this: "Plutus: Writing reliable smart contracts"

For anyone interested in Plutus, please consider joining @CardanoProjects to connect with other developers and stakeholders.

Search Udemy for this: "Plutus programming language"

They are both official, in the sense the authors are from IOHK / Cardano

Like I said, general advice for first step: learn Haskell fundamentals, get very comfortable with writing simple programs.

You're welcome. We are always looking for new members.

Great, thank you all for your valuable information!

there's the x86_64-unknown-linux-musl build

I know, but in all previous builds there was also a glibc build

Don't Trust. Verify.
what is musl? i am not familiar

alternative to glibc, statically linked though so the binaries don't depend on a shared lib

I'm not sure if you can link musl as a shared lib even?
