Dataans v.0.3.0 ➡️ tbt.qkation.com/posts/dataan...
The most important feature in this release is multi-device data synchronization.
I was frustrated about it because the path to the final solution was rough. Such a simple feature turned out to be hard to implement. More in the article 😉

Me and my friends were camping for 3-days. We needed to cover each other's debts. Fortunately, we found kittysplit: kittysplit.com. It does not require any sign-ups! It simplifies this process a lot. We no longer need to do it manually or semi-manual in Google Sheets

It took me three times more code and twice as much time as I initially estimated.

So, if you ever wondered (most likely not) about such things, this is your chance. 😉

There is one thing I forgot 🙈
There are use cases when return Err(/* ... */); is better. Thanks @dzuchun for reminding me that (t.me/tbtpm_chat/2...). Let me show you an example:
```
if name.len() > 5 {
// ---- value moved here
Err(name)?;
}
Ok(name)
// ^^^^ value used here after move
```

The only acceptable way to return an error from a function: `Err(Error::new(/* ... */))?;`
Any other options are mental disorders from the previous experience with other languages 🧐
