Contracts are a means of setting preconditions and postconditions on function declarations, and adding assertion statements within functions. The feature is intended to help make C++ code safer and more reliable.

New overloads on TarFile.CreateFromDirectory accept a TarEntryFormat parameter, giving direct control over the archive format. Previously, CreateFromDirectory produced Pax archives. The new overloads support all four tar formats—Pax, Ustar, GNU, and V7—for compatibility with specific tools and environments.

While the codebase is fresh and grows fast under the umbrella of the local environment, we tend to rely on debugging tools, which were created specifically for that purpose. The app is half-baked, and the code is split open. We observe it through the lens of our IDE and with the speed of our brain. Everything is possible; we may pause execution for minutes, and the whole system is a white box - an open book for us.

Companies hiring developers with several years of experience expect candidates to demonstrate practical reasoning about functional programming patterns, concurrency models, and the Scala type system. A mid-level engineer is usually expected to work independently, contribute to design decisions, and understand the trade-offs behind the tools they use.

Tracy is compatible with Kotlin from version 2.0.0 and Java from version 17. Integrations can be made with SDKs from OpenAI, Anthropic, and Gemini. The library also works with common Kotlin/LLM stacks including OkHttp and Ktor clients, as well as OpenAI, Anthropic, and Gemini ones.

We're pleased to announce the release of Scala 3.8 - a significant release that modernizes the Scala ecosystem and paves the way for Scala 3.9 LTS. This release introduces a standard library compiled by Scala 3 itself, stabilizes highly-anticipated features like Better Fors (SIP-62) and runtimeChecked (SIP-57), and introduces experimental features including flexible varargs and strict equality pattern matching. A runtime regression was detected after publishing Scala 3.8.0 artifacts.

XAI just open sourced the X recommendation algorithm, and honestly, it felt like they massacred my boy. I scrolled down expecting to see language stats like the 2023 repo. You know the usual breakdown: Java, Scala, maybe some Python sprinkled in. Instead, there were only two languages listed. Rust and Python. That's it. Which immediately tells you this wasn't a refactor. This was a full rewrite.

A study from Dimensional Research shows that 92 percent of the 2,000 respondents reported being concerned about Oracle Java pricing, up from 82 percent in the same survey last year. Those stating they were very concerned about the changes leapt from 19 percent in 2025 to 29 percent this year. In 2023, Oracle changed its Java SE subscription model, shifting from a per-user or per-processor basis to per-employee.

JEP 527, Post-Quantum Hybrid Key Exchange for TLS 1.3, has been elevated from Proposed to Target to Targeted for JDK 27. This JEP proposes to enhance the implementation of RFC 8446, Transport Layer Security (TLS) Protocol Version 1.3, using the Hybrid Key Exchange in TLS 1.3 specification, currently being drafted by the Internet Engineering Task Force (IETF) in conjunction with JEP 496, Quantum-Resistant Module-Lattice-Based Key Encapsulation Mechanism, delivered in JDK 24.

From the discussions in the Jakarta EE Platform call[s] the last couple of weeks, it looks like we won't see a release of Jakarta EE 12 on this side of summer (on the Northern Hemisphere at least). The reason is that since Jakarta EE 11 was delayed by a year, most of the vendors are currently working on their implementations.
