Sure - all sorts of stuff with type-punning in unions because much harder to understand when it's transformed into a whole series of casts to/from void/char , with the loss of checking that one gets from a union. Even withou

To add to this, a lot of what compilers decide is undefined isn't bizarre corner case code that rarely happens, but common and useful techniques that the compiler will happily demolish without warning. The 'defined' workaroun

Z runs during rush hours, I believe. I only see it before 9 am and after 5 pm weekdays. Also, you can transfer from the M to a whole bunch of other train lines depending on where you are going. It's not the best, but it isn't terr

This article discussed Java, so I used Java. Also, C#'s value types are somewhat limited aren't they?

They've mostly been in the epoch manager itself - some were recently resolved, one has been pseudo-resolved by not freeing the respective memory, and I'm working on another right now. They're all edge cases, but they manifest

Something this doesn't mention is that for a given program written in both Java and say C++, the C++ version will have to perform much fewer allocations than the Java one. Escape analysis can help with this but afaik it's not even

Usually, financial companies will use one of the commercial realtime jvms - it's not just some tuning. Javascript being singlethreaded would certainly simplify having a pauseless GC but it's still a nontrivial problem and I'm

> The garbage collection in your web browser is complete, utter garbage compared to what Lisp people were doing 30-40 years ago. Sorry! Can you back that statement up? GC has advanced heavily over the years (and still is).The first paper

HFT firms pay very well for systems and HPC developers, especially when you count the bonuses. I'm not sure when/if the total salary reaches 500k, but I've heard that total salaries from 200-300k are fairly common. A recent g

I hope you realize that stack allocation can replace a lot of allocation that would be done by a GC? And that having control over memory layout can lend itself to better performance? And that naively mallocing everywhere is not the only or

I haven't used Haskell in a production environment, but I ended up removing core.typed from my Clojure core since it often fell apart/became prohibitively verbose when dealing with nontrivial functions and higher kinded types. It

There is still a lot of Fortran being written, but a lot of it is on legacy projects (scientific codes have a habit of lasting a long time). While there are some cool things like coarray Fortran and some groups require that everything be do
