Side note: Descriptive variable names make debugging (or code reviewing) much easier - names like x, y, c, t1 etc are difficult to follow as they don't mean anything (unless you made them!). — Samuel Everson 36 secs ago
In Ruby variables and method names are snake_case, not camelCase. ItIsAReadabilityThing. Pay attention to that if you every intend to program as part of a team as they'll call you out in a code review.

It's installed on Ubuntu by default, and probably also on Debian (as long as you have a desktop installed).

12:36 PM
400 is a value. 400 is how we display that value in decimal. You are looking for opcodes, not the literal string cmp xxx, immediate. Chances are there isn't even a cmp. More like just a dec, followed by a conditional jump (jz or jnz). If that has you stumbling, stop doing whatever you were trying to do. You will break things. Post your code at Code Review, and have someone optimize it, to help you regain your lost time. — IInspectable 1 min ago

I was influenced by this comment:
Your code is full of black boxes. FE, all these UnitOfWork and the classes you store. That makes a good review impossible. — Gert Arnold 2 days ago
@Vogel612 Is that ^^ not a valid concern, enough to make it off-topic?
 
3:58 PM
while it's a valid concern, it doesn't disqualify the question completely
 
@Mast thanks for your comment here:
I’m voting to close this question because it poses a specific question, there is no request for review. Please take a look at the help center. — Mast 2 days ago
I had a similar sentiment except the OP included this text: "If it is not is there any way to improve it?"
 
@Vogel612 We've closed and kept open other questions for the same reasons. I hate the reason cause it changes so much day to day.
 
@Peilonrayz I'm contemplating removing my comment since 1. the title has been updated and 2. that statement about the consensus likely isn't accurate
Welcome to Code Review! The current question title, which states your concerns about the code, is too general to be useful here. Please edit to the site standard, which is for the title to simply state the task accomplished by the code. Please see How to get the best value out of CR: Asking Questions for guidance on writing good question titles. Also, while it isn't exactly a mirror scenario the consensus is that questions about the complexity of code are off-topicSᴀᴍ Onᴇᴌᴀ May 28 at 21:25
 
@SᴀᴍOnᴇᴌᴀ Is that meant to be an at or a reply? Because if it's a reply I edited the source comment to be clear I'm not talking about that question.
 
@Peilonrayz I replied to your message because it seemed related - mostly about the close reason
 
4:10 PM
To me they're totally different. One's a clothes line with a ridiculous amount of slack, where the other's unclear if we want a clothes line or not.
 
@Vogel612 It's missing review context.
But possibly that can be alleviated by more accompanying explanation too.
If someone decides it's worthy of the effort and fixes it up, I may reconsider my vote. But for now, the question is all over the place yet not in a good one.
Left a comment. Possibly as unclear as the question itself, but it should trigger a response with hopefully helpful information. If anyone disagrees with it, I'll see it in the morning.

This migration won't enable header IDs. This migration is already a big thing so we don't want to conflate adding new features with running the migration itself.

Q: C - Fast & simple bump allocator

XilpexI recently have been very interested in custom allocators, so I decided to make the very basic (this should be faster than malloc) bump allocator.

I don't think it should affect testing, as the code should be exercised whether as a result of an if clause or a bit shift. There may be some code coverage tools that are confused by such tricks (especially the second one), but that's why you employ humans, right? I wouldn't say it's arbitrary; if you have a single method with a cyclomatic complexity over, say, 50, that's probably too high and your method is likely doing too much. However, as a code reviewer, if I see a ton of code with tricks like those shown, I'd be making sure the test suite is very comprehensive. — Heretic Monkey 6 secs ago
