OMEMO ensures neither room consistency nor transcript consistency. In fact, last time I checked you could easily send different transcript to different participants (for example by simply not providing them decryption key or providing an in

My impression was that gtk has pretty reasonable tutorials, at least for those languages with official bindings. Once you go through tutorial, you can examine gtk-widget-factory app and gtk-demo app for further ideas how to implement commo

I do recommend Behave. Robert Sapolsky is terrific writer. Though, I found it quite funny how in each chapter Sapolsky starts by describing usually story, criticising how it is wrong and too simplistic, elaborating on complexities involved,

In C++, you can for example: 1. Manage resources with RAII (though, in C you could use non-portable attribute cleanup in similar manner). 2. Use type safe wrappers around builtin types like in [0] and [1]. 3. Use containers with more extens

In pre C++11 it was quite typical for std::string to be implemented with COW semantics. Since C++11 standard it is no longer permitted, though it is not necessarily reflected in all stdlib implementations.

Using unsafe blocks and pointers can silence the borrow checker, but that doesn't mean that code is well defined. For example, using swap (mentioned in the article) with overlapping references would be undefined behaviour.

I would argue to the contrary, especially that we are comparing modern Clang/LLVM with a GCC that was released back in 2008. At that point C programming language didn't even have a memory model.

I think you are looking at the side that does the reading. I was actually thinking about the other side that does the writing (inside pthread_mutex_init), where those two things are not separated by any function calls and are more readily r

In case someone is interested, here is relevant code [0]. Notice that mutexp is read without any synchronization, and _spinlock further down uses different lock than one in initialization code (former is specific to this mutex and latter

Now that OpenBSD has an optimizing compiler maybe they will notice and fix dataraces in their pthread_mutex_lock implementation. Currently they use broken double-checked locking pattern when mutex is lazy initialized with PTHREAD_MUTEX_INIT

That is good point, so far I see one potential explanation, but it presumes that clients are on equal footing with other peers in the system. Whenever you send a write and destination discovers that it doesn't have all of writes operat

A lot of undefined behaviour on this list is quite specific to the C programming language, so it would be like comparing apples to oranges. Though, one major impression I think you will get after going through this list is that there is no
