SPARK Ada

“if security was taken as seriously as in any other industry then all of the above languages would have been written in SPARK”

“after using Spark for a long time, I think for most workloads, it's just not really needed any more. Too complex, too difficult to tune.”

“tools like Ark and Spark that make having access to the Lightning network something that the average person can muster”

“memory safety is very strong, formally provable. Has no GC. Excellent performance. Very mature.”

“The latter is mature and used in some parts of the software industry today.”

“or is integrated with specific programming languages like SPARK, Frama-C or this Verus”

“via static enforcement via Spark and compilers were able to optimize them nicely”

“Ada/SPARK have been on huge, high-assurance, high-safety applications for decades”

“Just rewrite the engines in Rust and SPARK Ada running on seL4.”

“a very interesting language, that can prove program correctness at compile time”

“Embedding proofs into the code that prove absence of runtime errors lets the bot know what your actual intent is”

“the only industrial strength, actually practical and pleasant to use formal verification language: SPARK”

“a SPARK Ada or other implementation that shows no code injections could ever happen from loading, modifying, or rendering text”

“The syntax is Pascal-like, which some people used to C-family languages dislike but I personally find nice.”

“you can actually embed a proof in the code so that you actually know that the code is correct”

“Ada/SPARK has the strongest verification story and decades of space heritage, but the development cost is higher.”

“We passed on Rust for Ada/SPARK2014 to write to bare metal on Cortex-M processor”

“They seem to ignore the existance of Spark, so even if you specifically want to use JVM it feels clearer and simpler”

“we need to switch to Ada/SPARK or some other type of formally verifiable system”

“NVidia rather use Ada/SPARK instead of Rust for their automotive systems”

“features which I wish mainstream languages would have, particularly regarding the formal verification utilities of SPARK”

“I'd rather fly in an airplane with a system coded in Ada/Spark rather than Python”

“it is still in development and more robust than the C/C++ (and likely Rust) toolchain”

“it would be more prudent to let the LLM generate Ada/SPARK because it can formalize and prove a wider scope than Rust”

“Spark's a pretty good renderer for it after you've generated the gaussian splats.”

“It turns any device into a deployment target without needing Kubernetes or heavy runtimes.”

“before you know it, your program is filled with proof statements”

“You can completely eliminate use-after-free, double-free, dangling pointers, memory leaks, and null dereferences.”

“My initial enthusiasm for the idea of Ada and Spark evaporated when I saw how much ceremony the code required.”

“Ada/Spark is for me ahead of Rust both in term of features and user experience”

“Ada and especially Spark makes it a whole lot easier to produce correct software.”

“Ada is having a bit of a resurgence with stuff like NVidia picking SPARK”

“if you want to produce auditable high-integrity, high-assurance, mission-critical software, you should be looking at SPARK/Ada”

“Ada with SPARK is very difficult to scale to larger projects”

“SPARK can be used incrementally, proving lower level or critical parts first.”

“Doesn't that make it extremely difficult to use for larger projects?”

“it has such a neat type system, pre- and post-conditions, formal verification”

“SPARK provides machine-checked formal verification that proves absence of runtime errors, bounds violations, and functional correctness at compile time”

“if you want even safer, high-integrity, and formally verified code on Android!”

“Ada and SPARK fulfilled the promise of a safe systems language decades ago”
