The Magic of Deep Linking

jDeploy Newsletter • 84 implied HN points • 10 Feb 26
🕹 Technology Java
  1. Deep linking is critical to a smooth desktop app experience because it lets links open directly in the native app instantly, avoiding slow web reloads and reducing friction.
  2. Making apps behave as singletons on Windows and Linux is essential so opening a link brings the existing app to the front instead of launching new processes or windows, which saves RAM and avoids clutter.
  3. jDeploy 6 delivers a cross-platform deep-linking solution for Java desktop apps by adding singleton support, simple package.json flags (singleton=true and urlSchemes), and a small desktop library to handle URL/file callbacks.

How to Deploy a Java Application Using Supervisor and Set Up Log Rotation

Vasu’s Newsletter • 13 implied HN points • 18 Oct 24
🕹 Technology Java
  1. Use Supervisor to keep your Java application running smoothly. It automatically restarts your app if it crashes.
  2. Set up log rotation to manage log files effectively. This helps prevent your system from running out of disk space by rotating and compressing logs.
  3. Make sure to test both the application and the log rotation. Checking logs regularly ensures everything is working as expected.

Fairy tales in password hashing with scrypt

Thái | Hacker | Kỹ sư tin tặc • 0 implied HN points • 19 Apr 14
🕹 Technology Java
  1. scrypt, a password-based key derivation function, is commonly used for password hashing but wasn't initially designed for this purpose
  2. Using scrypt incorrectly, such as with file encryption API instead of proper password hashing, can lead to weak security vulnerabilities
  3. When developing a crypto library, it's important to conduct user studies to ensure developers are using it correctly and securely

JWT Signing And Verification Benchmarks

ciamweekly • 0 implied HN points • 23 Feb 26
🕹 Technology Java
  1. The piece benchmarks signing and verification performance across different JWT algorithms to compare how they behave under load.
  2. The measurements use a Java JWT library (fusionauth-jwt) to get practical, implementation-level performance data.
  3. Benchmarks aren’t universal — you should run your own tests and make sure the results apply to your specific use case.

How to write beautiful Java

Tecnica • 0 implied HN points • 28 Jul 24
🕹 Technology Java
  1. Using streams in Java can make your code cleaner and easier to read. It helps you focus on what you want to do instead of how to do it.
  2. Instead of checking for null values with messy if statements, use Optionals for a more elegant solution. This can make your code safer and cleaner.
  3. Refactoring your code with these techniques can greatly improve its quality. Small changes can lead to a more enjoyable coding experience.
