@Hosch250 I don't think we should be updating. We have to find what causes the issue and solve that instead
we don't need any of the updates so increasing the dependency version only limits the number of people that can use the package
certainly considering it's only for testing
did you try creating a new solution and adding vsd as a reference?
If everything works fine then it's isolated to the test project

OK. I'll do my PR now, and you can take a look when you want.

I don't check that.

@Kevin Krumwiede - Thanks for your question. I believe it isn't clean because let's say that you have 50ish variables, and you have created a function in a different file (I have transitioned from C to Java so I don't the equivalent of function or method in JAVA) to declare these variables. I think it will be not a good experience for code reviewer to go back and forth between declaration piece and usage (setting) piece. Right? I'm new to JAVA world, so I am not sure the best way to handle this. I'd appreciate your thoughts. — watchtower 1 min ago

@Hosch250 I thought yesterday, crap, the WalkTree method works like a filter for the list but as I was already on my way to bed I couldn't fix it anymore. I've rewritten my answer.
 
OK.
I've already changed it.
@t3chb0t You know, the nonReadonlyFieldMembers and membersCanBeReadonly variables both point to the same item.
I'm not sure if it is worth it to rename it?
Even changing the value of one changes the value of the other, which isn't really surprising, but...
 
I was asking myself the same question...
I have one more idea about WalkTree...
private static void WalkTree(SemanticModel model, SyntaxNode node, Action<IFieldSymbol> processSymbol)
{
    // todo check whether node is reference to a field
    // check whether reference is assignment or ref/out param
    foreach (var child in node.ChildNodes())
    {
        if (child is ConstructorDeclarationSyntax)
        {
            continue;
        }

        var symbol = model.GetSymbolInfo(child).Symbol as IFieldSymbol;

        processSymbol(symbol);

        WalkTree(model, child, unassignedSymbols);
 
I thought about that myself.
Feel free to post it as a suggestion.
 
@Hosch250 what do you think about this. the WalkTree method does nothing but scannig the tree and you handle each item with a separate method
 
I could do that easily enough if I used dynamic.
No, I'll do as casts and null checks in each item.
...
The one is ugly, and the other is slow.
 
5:05 AM
there's no need for dynamic
 
It wouldn't work anyway, since I'm wouldn't have a method to handle each node type.

Q: Must declare function prototype in C?

Mohit DeshpandeI am kind of new to C (I have prior Java, C#, and some C++ experience). In C, is it necessary to declare a function prototype or can the code compile without it? Is it good programming practice to do so? Or does it just depend on the compiler? (I am running Ubuntu 9.10 and using the GNU C Compile...

But if I'd have to summarize, I'd say that.. generally speaking, you don't need to explicitly declare functions because defining them already does also declares them. Here are two situations where you would need to:
1. The definition of the function is in an external module. (For example, if the function is defined in foo.c, but you want to call it from bar.c, you will need to declare the function in bar.c or a file included by it (typically, foo.h).
2. The definition of the function comes after a call to it (For example, if you have two functions that call each other, you will need to declare the second one before the definition of the first one).

@t3chb0t I think I have to do so indeed
 
is regex101 broken or is it only my machine? it doesn't want to parse even a simple number anymore regex101.com/r/J35T5w/1
lol
how did I come up with the idea to write the string inside the regex field? embarassing
 
@t3chb0t move the Row + offset and Column + offset in the rect.Contains call and only create a new Coordinate when that is true
then you get rid of those unnecessary allocations
 
1:25 PM
@JeroenVannevel but I need this throw-away coordinate to compare it with the current one so that I can skip it. if I move the addition then someone will say I do four additions instead of two, this is insane ;-)
 
do the equality checks separately then
you're doing them anyway with the equality operator
I wouldn't accept your solution either because of the unnecessary allocations
 
you're joking now, aren't you?
 
I'm not?
You turn a solution with 1 allocation to a solution with potentially 9

I would be really surprised if I say a dependency on Rectangle for such simple code
 
@skiwi This can probably be improved by using Math.Min and Math.Max rather than the intermediate boolean values but I can't be arsed to look into it
 
1:33 PM
And I disagree with the OP saying the level of clunkiness is the same
@JeroenVannevel True that, it looks weird to me in the first place
 
@skiwi why should I write 8 lines of code for checking bound if I can use the rectangle and do it with only single line?
 
@t3chb0t Because you surprise other maintainers with your Rectangle class
 
oh no, Math, another dependance
 
you're being petty
 
@skiwi how do you mean surprise? they can take a look at the docs anytime
why can math be used but rectangle not?
 
1:35 PM
End result is that you do allocations that aren't necessary and can be removed with small additions
 
@t3chb0t Imo the tools you are using are too complicated for the problem you are solving
 
allocations that no one can even say how much they cost... well, I like to keep my code simple and use all available references (as long as I know they exist) rather then write everything by myself.
@skiwi well, I didn't have to write any logic but a simple if and a few pretty obvious comparisons wherease the other solution has like 4 ternary operators, 4 comparisons || and plenty of magic numbers for some magical logic where you can make at least 20 mistakes... ok, your choice

Q: python reduce sqlite3 db lookups

Muhammad AnnsI am trying to reduce sqlite3 db look ups in python. I have system with limited RAM of 1 GB only where i am implementing it. I want to store current DB values somewhere from where i can retrieve them without consulting DB again and again. One thing to keep in mind is that trigger point of all of ...

@skiwi Oh, it unhung itself.
 
@denis Your question lacks an intro.
What does your code do and why did you write it? You start with a link, but questions should be stand-alone.
 
I will add the description of the problem into the question's body instead of referring to a question @Mast.
 
@Mast Expensive, but cool.

We need to keep an eye on this user: codereview.stackexchange.com/questions/151268/…
That comment is OK, but I'm seeing them escalate things pretty badly in a few places.
 
4:46 PM
@Hosch250 Agreed. Question needs more VTC.
 
Yup, mine was the first.
 
@denis Better, but you still haven't told us what it's supposed to do and why.
 
the goal is to avoid the usage of System.Reflection I think this summarizes the use of the class, or do you mean like a list of functionalities/features ?
 
If you want to avoid using something, stop writing code.
That's not a goal.
Do you want to by chance? Why do you want to avoid using System.Reflection and what do you want your code to do?
 
@denis I think speed is an importat factor because otherwise one could just use reflection
 
4:52 PM
@Mast I will add more info on that, but how is that not a goal ?
 
worth mentioning, at least by a tag

Q: SPOJ - Aplha Code - Exceeds Time Limit

Uma KanthI'm trying to solve Alpha Code on SPOJ. http://www.spoj.com/problems/ACODE/ It works fine for small numbers but exceeds the time limit for bigger numbers.

Q: Rust recursion pattern in simple cat program

IanGilhamI'm trying to get my head around recursion in Rust. I've put together a basic implementation of cat here to play with the basics. Here's my recursive version: use std::env; use std::fs::File; use std::fmt::Display; use std::io; use std::io::BufReader; use std::io::prelude::*; use std::path::Pat...

 
@denis What do you want to achieve, regardless of existing methods to accomplish it?
Usually you have a problem and use solution X to solve it.
Now you have a problem without stating the problem but stating you don't want to use solution X. So you're looking for solution Y without telling the problem.
 
That makes sense @Mast will update it to reflect that + I will add the tag the @t3chb0t mentioned.
 
@t3chb0t Isn't speed always a factor?
 
4:59 PM
Here the speed is the goal of the whole thing
 
@Mast rarely, I'd rather write something quickly with linq that works properly then spend hours optimizing something that no one ever will notice, if something needs to be fast that it's a clear requirement and one needs more time
 
@t3chb0t Answered one of your questions that was over a month old.
 
@t3chb0t Why would I need to pass a delegate around in my Roslyn question? Why couldn't I just call a static method directly?
 
This would be off-topic for Code Review. You're presenting heavily simplified code where Code Review requires the real deal. You're also not interested in optimization but more in why something is faster than something else. That's code explanation, another thing we're notoriously reluctant to accept. On top of that you're encountering errors, which would make this code considered broken. Please check the Code Review on-topic help centre for more information before posting there. — Mast just now
 
I know it's not particularly substantive, but I tried to put enough in there for it to be worth it. :)

@Mast How does that looks to you ?
 
@EBrown you don't like my var position = (int?)null; :P I forgot to put a warning about it in the question :)
 
@denis Much better, have an upvote.
 
@t3chb0t No, nor your var range = (CronRange?)null;. Lol
> Overall, excellent work here. It's always nice to see your questions as they tend to be very good code-wise to begin with, the worst I can find here is a few nitpicks. :)
As always, my default sign-off.
 
Thanks @Mast now I'm just waiting for someone to answer it -_- .
 
5:03 PM
@denis If it gets far enough up the C# zombie list I'm going to be working on it. ;)
 
@denis It already has an answer...
 
We have 207, I want to be down to ~100 by the end of January.

Sorry @t3chb0t but I'm looking for more in-depth review :/
Tho you still have my upvote as the answer is valuable.
 
You could always post a follow-up once you've waited long enough.
With the revised code.
 
@denis there's nothing to be sorry about, you pick the best answer and I know this one isn't complete (yet) as I didn't have the time to study the code completely
 
5:05 PM
Most of these C# zombies are either: long, already good, or difficult problems to solve. I think it's a good challenge to scratch them off one-by-one.
2
I already learned several things from answering a C# zombies.
2
 
I looked at several, but a lot of them involve DB's.
 
I might dig on some zombies to later today.
 
I've never worked with a DB in code.
 
@denis Don't be fronting on my turf. ;)
 
Yup, answering zombies can be a great educational exercise.

5:06 PM
(I'm kidding, I'd absolutely love if you would help out.) :)
@Hosch250 It's really easy.
 
@Hosch250 Sounds like you're about to learn something.
 
@Mast Yeah, except I'm already learning things.
I don't want to start yet another project...
 
Fair enough.
 
@EBrown I finally understand (I think I do) how async/await works by answering some questions, @denis question is for example one of those where you can learn a lot of cool stuff but it cannot be reviewed in even 2h, it requries much more
 
At least, not at the moment. It is very high on my list of things to learn.
@t3chb0t Go read about it in C# In Depth :)
 
5:08 PM
@t3chb0t Oh yeah, I had no idea how async/await really worked until I answered a few (long ago), I recently learned how CultureInfo works by reading and answering an old zombie.
 
You should be able to get it from the local library system.
 
Most of my C# answers within the last ~5 days have been zombies, ~330 rep from it.
 
 
@Hosch250 I did, but it's not the same as doing it yourself, besides I don't find books particularly useful :P I've learned more from msdn and SO
 
@t3chb0t The OP's code was also really well put together, it took me sometime to figure out improvements or any additions that I can propose.

@Hosch250 I've seen that one it's a good question indeed, but I'm not really into security to detect any flaws so I'm avoid it ^^
 
@denis it's not that I don't want to review it, it's just pretty complex so I need to run it for my self in VS with all the tests... I want to learn something from it not only writing, the naming is bad :P
and I'm not an expert with expressions but this one seems to be a nice start to using them more often
 
@Hosch250 I keep skipping that one for the moment.
I'll get to it when I have more time.
 
expressions?
 
5:18 PM
right, expressions
 
what do you refer to with "expressions"?
 
expression trees
 
expression trees
 
expression trees
 
expression trees
 
5:19 PM
:-)
 
where are the expression trees in that question?
 
@JeroenVannevel btw, I run a few simple benchmarks and all three versions of finding neighbours are virtually equaly fast, the difference was maybe 30ms for 10mln calls, it's like nothing :)
 
aha
it's not about speed, it's about memory impact
 
there seem to be no noticable overhead in using throw-away structure instances

This is still hideous. I can't believe that would in any way pass a code review. — Jared Smith 36 secs ago
 
well, they don't have to be garbage collected so I guess they vanish as soon as you don't need them anymore
 
I'm not saying it would be a big issue but if you can have equally clear code and one of them has less allocations, I see no point in going for the one that has more

Hello @Vogel612
@EBrown Can you show me your list of zombies :?
 
5:30 PM
I don't have any.
 
Oh well nvm than
 
I have three questions without accepted answers, if you want to answer any of them.
But one is over a month old (almost 2) and I'll probably accept the answer on it here shortly.
@denis This this and this.
They're also three different languages, humorously enough.
 
@denis you can search for candidates [c#] closed:no hasaccepted:no
 
One of them I selfie-answered, since it was probably going to become a zombie.
 
C# only :/ luckily there is one but I haven't worked with wpf all that much I can take a look tho.
 
5:36 PM
I just answered a zombie without a single line of code: codereview.stackexchange.com/a/151274/34073
 
is it even legal? :P
 
@t3chb0t you can even restrict by things like score:2 answers:0
 
yup, I have the search parameters link bookmarked
 
@t3chb0t It is but the opposite is not, or at least it usually is not well received..
 
@denis It depends, there are many answers on this site without a line of code. A lot of times saying something about the algorithm itself in human-form is as valuable (or better) than writing code. You can also write an entire review here without putting a single bit of code in it by describing the general issues and how to fix them.
 
5:42 PM
@denis sorry, I'm afraid I don't follow you - OutOfThreadsException
ok, I'm back
it was about whether it's legal
 
@EBrown I mean that answer that consists only of pure code is not well received.
 
@denis Ah, yes. In the case that an answer is only code it's pretty much unfit here.
 
@denis yea, but that has reasons deep within the philosophy of the site
 
And that boosts me to 60/80 and 340/400 for a silver .
 
5:50 PM
there is probably no search option like didn't answer it mayself?

Q: Do Americans swap wives because Americans eat pigs?

What a stupid question.
 
Do they?
 
mhmm, this isn't serious? is it?
 
I've not even heard of that in first-world countries until now, so I'd say no.
 
heard of what?
 
5:54 PM
Do Americans swap pigs because Americans eat wives?
 
Wife swapping.
 
Pigeating, wifeswapping or the causality?
Wife swapping is totally a thing though
causality is bs, the other two occur
 
Do pigs eat Americans because Americans swap wives?
 
I'd heard of it in Inuit culture, but that's it.
Anyway, I meant it was stupid because of the causality question.
Just as a reminder, correlation != causality.
 
Btw anyone used Beautiful soup?
