Static dev domains for all ngrok users | ngrok blog
Jan 8, 2026: We updated this blog post to reflect our new pricing and the transition from static domains to dev domains. One of the major complaints users have with ngrok is that the URL changes every time the agent restarts. Every ngrok account now comes with a free dev domain to alleviate this issue. Dev domains are automatically assigned to your account and remain yours as long as you have an n

BLisp: A Statically Typed Lisp Like Language
BLisp is a statically typed Lisp like programming language which adopts effect system for no_std environments. BLisp supports higher order RPC like higher order functions of functional programming languages.
Error Prone
Error Prone It’s common for even the best programmers to make simple mistakes. And sometimes a refactoring which seems safe can leave behind code which will never do what’s intended. We’re used to getting help from the compiler, but it doesn’t do much beyond static type checking. Using Error Prone to augment the compiler’s type analysis, you can catch more mistakes before they cost you time, or en

GitHub - GaloisInc/crucible: Crucible is a library for symbolic simulation of imperative programs
Crucible is a language-agnostic library for performing forward symbolic execution of imperative programs. It provides a collection of data-structures and APIs for expressing programs as control-flow graphs. Programs expressed as CFGs in this way can be automatically explored by the symbolic execution engine. In addition, new data types and operations can be added to the symbolic simulator by imple
GitHub - NASA-SW-VnV/ikos: Static analyzer for C/C++ based on the theory of Abstract Interpretation.
IKOS started as a C++ library designed to facilitate the development of sound static analyzers based on Abstract Interpretation. Specialization of a static analyzer for an application or family of applications is critical for achieving both precision and scalability. Developing such an analyzer is arduous and requires significant expertise in Abstract Interpretation. IKOS provides a generic and ef
GitHub - smackers/smack: SMACK Software Verifier and Verification Toolchain
SMACK is both a modular software verification toolchain and a self-contained software verifier. It can be used to verify the assertions in its input programs. In its default mode, assertions are verified up to a given bound on loop iterations and recursion depth; it contains experimental support for unbounded verification as well. SMACK handles complicated feature of the C language, including dyna
