Fuzzing finds bugs by testing software behavior with high volumes of input. To create semantically valid inputs for different targets, traditional fuzzers require significant engineering effort. LLM-based fuzzing approaches can be adapted to create inputs for a wide range of software but introduce new issues: every test needs an LLM query, sacrificing the speed of traditional fuzzing. We introduce Typed Template Fuzzing (TTF). It uses LLMs in a preprocessing step to create templates which encode semantic information of seed files. These templates enable semantically-aware mutations without the need for a parser, type-checker, or further LLM queries. We have implemented TTF in our tool Typos. Using Typos we have run a five-month fuzzing campaign, finding 97 previously undiscovered bugs. Typos achieves a 94.7% rate of valid inputs across a wide range of formats including SMT-LIB2, C, C++, Go, Rust, SystemVerilog, Scala, Java, and domain-specific libraries such as PyTorch and Qiskit.
This publication proposes a definition and a classification of agile software development approaches and analyses ten software development methods that can be characterized as being "agile" against the defined criterion.

The study shows that agile practices improve both informal and formal communication, but indicates that, in larger development situations involving multiple external stakeholders, a mismatch of adequate communication mechanisms can sometimes even hinder the communication.

The results show that the embedded industry has been able to apply agile methods in its development processes and that the appreciation of the agile methods and their individual practices appears to increase once adopted and applied in practice.

Requirements in large systems rarely exist in isolation. Their meaning depends on the wider project context - other requirements, policies, decisions, tests, and implementation details. That becomes especially important when AI is used for review, because spotting a possible conflict or gap is only the beginning. ReqSpace explores how AI, visualisation, and connected project context can help reviewers understand those findings, trace the relationships behind them, and focus on the questions that…
AI is making software generation faster, but speed does not remove the need for expertise. As more work is delegated to AI, tacit knowledge may become one of the most important human advantages in software engineering.
