• A Big Thank You Community! KDE Snaps resumed and More.

  After my last post a few things have happened. First, I want to thank all of you for your support, monetary and moral. The open source community is amazing and I love being a part of it. We are surviving thanks to all of you. Despite my failed interview, a new door has opened up and I am happy to announce that Canonical is funding me to work part time for a period of 3 months on KDE Snaps! While not the full time role I was hoping for, I'll take it, and who knows, maybe they will see just how awesome I am!

• Niko Matsakis: Must move types

  Rust has lots of mechanisms that prevent you from doing something bad. But, right now, it has NO mechanisms that force you to do something good¹. I’ve been thinking lately about what it would mean to add “must move” types to the language. This is an idea that I’ve long resisted, because it represents a fundamental increase to complexity. But lately I’m seeing more and more problems that it would help to address, so I wanted to try and think what it might look like, so we can better decide if it’s a good idea.

• Niko Matsakis: Temporary lifetimes

  In today’s lang team design meeting, we reviewed a doc I wrote about temporary lifetimes in Rust. The current rules were established in a blog post I wrote in 2014. Almost a decade later, we’ve seen that they have some rough edges, and in particular can be a common source of bugs for people. The Rust 2024 Edition gives us a chance to address some of those rough edges. This blog post is a copy of the document that the lang team reviewed. It’s not a proposal, but it covers some of what works well and what doesn’t, and includes a few sketchy ideas towards what we could do better.

• What are Varargs in Java and How to Use Them

• What are Java’s Access Modifiers and How to Use Them

  In Java, access modifiers are keywords that determine the accessibility of classes, methods, and variables in an object-oriented program. There are four access modifiers in Java: Access modifiers are used to control the level of encapsulation of an object-oriented program and to restrict access to sensitive or implementation-specific details of the program.

• How to use Yield in Python

  In Python, Yield is a keyword that allows you to pause and resume a function's execution, effectively turning it into a generator. The Yield keyword is used to produce a value from a generator function in Python and then pause the function's execution.
