Obversvations

  • CompreFace project looks pretty interesting if you want to try or use face recognition functionality in your application.
  • QuestDB one more player in SQL DB world used by such companines as Airbus, Toggle, Turk Telecom and others.
  • Solana is a clear leader in Rust’s “new starts” repositories, almost every monthly review Rust section includes any of Solana-related repositories. This month’s review is the Anchor project.
  • Starting newly with Rust or switching from other programming languages and don’t know how to implement a specific algorithm in Rust, so see The Algorithms – Rust repository.
  • Based on official documentation SWC is 20x faster than Babel on a single thread and 70x faster on four cors, if you use Babel and want to build your projects faster SWC is worth trying.
  • If Git CLI for some reason doesn’t work for you, there is a GitUI project which probably you want to try.

Constraints: Null, Empty, and Blank.

As I see there is some confusion related to validation annotations usage in Java. Let’s see a quick example of the three most confusing annotations from the Hibernate Validator.

@NotNull

public class User {

   @NotNull
   private String name;


   // ...
}
Value passedValidation result
<null>🍎 – validation failed
“”🍏 – validation passed
" "🍏 – validation passed
“Alex”🍏 – validation passed

Note: only null values are not allowed, emtpy value will pass this validation.

@NotEmpty

public class User {

   @NotEmpty
   private String name;


   // ...
}
Value passedValidation result
<null>🍎 – validation failed
“”🍎 – validation failed
" "🍏 – validation passed
“Alex”🍏 – validation passed

Note: null and empty size/length values are not allowed, values with multiple spaces will pass this validation.

@NotBlank

public class User {

   @NotBlank
   private String name;


   // ...
}
Value passedValidation result
<null>🍎 – validation failed
“”🍎 – validation failed
" "🍎 – validation failed
“Alex”🍏 – validation passed

Note: null values are not allowed and trimmed length must be greater than zero.
