Avoid referring to UserForm1 in the code-behind of UserForm1: that will not work as you expect, the minute you start New-ing up your forms. Use Me to refer to the current instance of the form. That said this code might interest youMathieu Guindon 19 secs ago

Q: Promise Library

Timhttps://github.com/timcassell/ProtoPromise I'm working on a C# Promise implementation (based off Promises/A+ and ES6 with some alterations). I'd like some feedback, if anyone has any to give. The most glaring issue it has right now is it is not thread safe, which I plan to get around to soon. O...

Q: C++ Leak detection simple class

As It isBasic idea is to use a Class, with static methods to add and remove references in a static vector, that keeps track of these references, and check that vector upon exit. The class is detecting intentional leaks that I create, but maybe you can find a case where it does not detect the leak, that ...

Could you provide your code in one code block? I'm interested in this, but I don't copy multiple code blocks. Also do you think there are class attributes, not instance attributes, that are defined in __dict__ but not on the type? — Peilonrayz 44 mins ago
@Peilonrayz Any time I've edited my code in a Q post here it's been rolled back, so I don't think it's wise to try to revise it.
or reorganize it even.
 
That's probably to avoid answer invalidation, but you have no answers so it won't matter here.

If you don't want to that's fine, it'll just deter some people - like me - from answering.
 
I use multiple code blocks to insert discussion and avoid scrolling code blocks. It's quite intentional and my preference to keep it the way it is.

Brainfuck interpreter written in C on codereview might give some ideas. Your use of the stack to handle nested loops is probably a good idea. — Peter Cordes 48 secs ago
subq $1,(%r12) is an 8-byte sub; your cells are 1 byte so you're allowing carry-out to propagate between cells. That's a bug, IDK if it's the cause of the problem you're asking about. Also related Brainfreeze: A Brainfuck compiler in C on CodeReview talks some about x86 asm sequences that implement BF "instructions". JITing vs. dispatch with a chain of branches isn't a big difference as far as what the blocks need to be. (And BTW, for performance you might want to dispatch via a jmp table(%rax) after a movzx load.) — Peter Cordes 13 secs ago

Q: Brainfuck compressor in Python

connectyourchargerJust for fun, I created a script called TinyBF which can compress Brainfuck programs into a format half their size. For example, take a famous hello world program clocking in at 78 bytes: --<-<<+[+[<+>--->->->-<<<]>]<<--.<++++++.<<-..<<.<+.>>.>>.<<<.+++.>>.>>-.<<<+. When put into TinyBF format...

 
research prototype codebases are a neverending source of pain
I need to work on a module in such a codebase that contains the model for implementing a spec
There's some fluff around serialization and deserialization of that model, but the most infuriating (at least right now) part of all the mess is that there are some entities in the model where instances have no field for their primary natural key
And there is literally zero documentation on why anyone thought that was acceptable in any way shape or form
ughhhhh and the spec was written in word and the pdf export doesn't expose an outline.

@Vogel612 Wat
Welp, that's kind of an important step not to forget.
 
yea, I'm very much weirded out by how apparently nobody though that might be a useful thing to have
all these entities are accessed through a parent entity which stores the children in a map.

@Peilonrayz @Vogel612 Such questions are a pain. I'm not sure if they should have been migrated. Probably best to have a dialogue with SO mods about this. The question surely fits better on CR than on SO, but the answers aren't good CR answers. Personally I'd recommend adding a comment and if possible, edit an answer to improve it (not too much, but just add a brief explanation about why that answer could be better than the original code)
@410_Gone If you use anything Kotlin, then yeah you would need that.
Nice to see that you're using Kotlin by the way :)

@SimonForsberg Yeah my Android project wouldn't build because a referenced project used Kotlin...which seemed odd to me
