I'd actually compare screen OCR to screenshots. Instead of every app and every website implementing their own screenshot functionality, the system provides one for you.

Same goes for text selection. Instead of every context having to agree on tagging the text and directions, your phone has a quick way of letting you scan the screen for text.

To be fair, I still use the "hold the text to select it" approach when I want to continue with the "select all" action and have some confidence that is going to do what I want.

I'm ~1900 which means first two rounds are typically beginners.

It's easier and quieter than stopping the clock and searching for a free queen piece if your position is decisive and your opponent stubborn. Or your piece to be captured immediately. So not necessarily "cocky" as the answers suggest but rather "mindful to other players".

A software engineering example: knowing that Postgres FK doesn't implicitly create an index. Three different projects I joined weren't aware of this and we managed to improve the performance with a negligible amount of effort.

Keen to hear your wins (and make them mine ^^

2. A key of a function is something like `keccak256(function's signature + docstring)`

3. A value is a list of the function's implementation (index being the implementation's version) and some other useful metadata such as the contributor's signature and preferred function name. (Compiler emits a warning that needs to be explicitly silenced if preferred name is not used.)

4. IDE hints and the developer confirms to auto import the function from the global KV store.

5. Import hash can be prepended with a signers name that's defined in some config file. This makes it obvious in git diffs if a function changes its author. Additionally, the compiler only accepts a short hash in import statements if used with a signer.

package.toml

  [signers]
  mojmir = "mojmir's pubkey"
  radislava = "radislava's pubkey"

  // use publisher and short hash
  import "mojmir@51973ec9d4c1929b@1" as log_v1;
  // or full hash
  import "51973ec9d4c1929bdd5b149c064d46aee47e92a7e2bb5f7a20c7b9cfb0d13b39" as log_latest;
  import "radislava@c81915ad12f36c33" as ln;

  log_v1("Hello");
  log_latest(ln(0));

Ie. engineering work needs to happen in the UI they used to confirm the tx

You can set the shell for some commands, for example:

```

set shell := [ "python3", "-c"]

# I can run python!

[no-cd]

foo-bar:

    @import sys; major, minor = sys.version_info[:2];

    assert (major, minor) >= (3, 7), "This script requires at least Python 3.7. Please link \"python3\" to Python 3.7 or higher and try again."

And the API for your commands stays consistent for a very little effort. Of course you can achieve all this with just bash scripts but I find it faster and easier to provide a good devex this way.

It was an excuse for a train trip to beautiful Vienna. Also, I met Jon Gjengset for whom I hold a lot of respect, especially his ability to think and talk and explain.
