@chillworld "Attention to detail", "structured thinker", and "Lucky" are all characteristics that seem appropriate for your resume... ;-)
C# Folk... I know I should keep my nose out of these places, but, is C# performance always such a guessing game? : codereview.stackexchange.com/q/55220/31503
Q: Vectorize Matlab sum

Seanny123I have the following Matlab function: function [res] = a3_funct(x) res = 0; for i = 1:size(x,1) res = res + abs(x(i))^i; end end It's emulating this equation: Here is an example use: >> a3_funct([1,2,3]') ans = 32 I know I should be able to use the sum() function...

Q: Better way of comparing integers

alexI wrote this class which is comparing some values, how can I improve its performance and maybe make it prettier? You can see at the bottom what type of data it requires, also the array size can reach 100 000 elements. As it is the class is working fine, but I would like to get a second opinion ...

Q: PHP : Is it possible to optimize two for loops and a foreach?

user3510209I'm writing a php function to collect data from different positions in an given array, I've done it as follows which gives me what I require. for ($a=9; $a < 13; $a++) { $n = $arr[$a][2]; $p = $arr[$a][3]; $c = $p; $v1[] = array($n,$p,$c); } for ($b=3; $b < 16; $b+=4) { $h...

@rolfl I don't use C# much either, but the last time I did, the profiler I used seemed to be pretty competent.
@JeroenVannevel I still think it's a bad design if a class about network connections starts to give UI popups by default... I could slightly understand it as optional
Haskell, what?
data PointSet s a where
    Halfplane :: RealFrac a =>
                 a -> a -> a -> (a -> a -> Bool) -> a ->

@skiwi Decoupling error detection from reporting is one of the (big) reasons nearly all reasonably modern languages include some sort of exceptions/exception handling.
@JerryCoffin But C# has exceptions, right?
@skiwi Yes, I believe so.
4:39 PM
Then it's a really messed up design there?
@skiwi Where? Not sure what code you're talking about.
A: Windows.Web.Http.HttpClient#GetAsync throws an incomplete exception when invalid credentials are used with basic authentication

Yuval ItzchakovAfter reconstructing your example and playing around, i figured out what happens. var data = await client.GetAsync(new Uri("https://mytestdomain/v2/apikey?format=Json")); The GetAsync method invokes the http request with invalid credentials. What happens is that the returned request tries to l...

It is code that does an async call to an URL, and returns the data
@skiwi I'm not at all sure, but it looks to me like that's not quite the case. Rather, it looks like an exception is being thrown somewhere deep down, and (by default) they install a top-level exception handler that simply displays a message if an exception was thrown, and nothing else caught it.
@ckuhn203 hope I didn't overlap too much: codereview.stackexchange.com/a/55240/23788 ;)
@JerryCoffin I see, that changes the case somewhat... yet still not what I would expect

A: Finding the largest mirror image of a subset of integers present in an array of integers

rolflThe algorithm you have chosen is not optimal. You scan all possible values and when you find a solution you remember it if it is bigger than the previous. Instead, what you can do, is work optimistically, and assume the solution will be big, and work backwards from there... then, you can exit wit...

4:58 PM
is this an answer?
A: Finding the largest mirror image of a subset of integers present in an array of integers

mjolkaAs your code has already been reviewed, I would just like to propose another solution: to find the longest common "substring" of the array and its reversal. Finding this by dynamic programming can be done in \$O(n^2)\$ time and \$O(n)\$ space.

beto_veHi there fellow coders, I am looking to improve the following query. We are using EF6 (CodeFirst) and C# Lambda Expressions, and Repository/Unit of Work patterns. Also, we needed to restrict the query in a way that we could inner-query the entities so that the query will only retrieve a subset...

Well. yeah, but, just because noone asks questions with sockets as the tag....
I don't think it overlapped too bad @Mat'sMug. When it did, it clarified what I was trying to say. You're gold.
lol thanks :)
It makes me feel like I did a pretty good job though. If you're worried about overlapping, I was pretty thorough.
A: Making a phone call in the background

CommonsWare Is it possible for my service to make a quiet phone call? No.

Such a descriptive answer.

Why is someone even trying to do that? I'd be furious if I found out an app I was running was quietly making phone calls in the background.

@Mat'sMug I don't know, are you abstract?

Stop smoking the documentation. It's bad for your health.
@ckuhn203 As if smoking something else is better for the health?
@Simon when you answer that two-pass question ....
you may want to point out that int arrays are initialized to 0 in Java ;-)
@rolfl What makes you think that I'm going to answer it?

this makes me twitch

Only valid reasons for Java 6 (or lowr) in my opinion are when you are writing general libraries intended for open source, or work at a company having only access to Java 6
All toy projects should be mandatory Java 8 by now! Well... Java 7 at least

Q: Why do we have to directly insert our code into a question?

Some GuyI have an issue about being required to insert your code into your question. This can be extremely annoying for many.

At least we here are mature enough to refrain from downvoting if closevoting is enough.

I think it's unfair to down vote if I vtc. If the question gets opened back up, it has a stigma attached to it.
Speaking of which, if you encounter an older (answered) question that only has a dead link, please flag it. There are still some around with code behind an intact link, but I haven't deleted them because the code was still available.

Q: Capture the notion of invertible functions

JavranI find sometimes it is useful to capture the notion of invertible functions.

Moreover, if there f' and g'...

As a moderator on SQA, I do not believe a general "review my software" would be welcome. However, you could probably achieve the same results if you took the "teach to fish" approach. You could probably describe a bit about the app and what your goal is (better usability? better reliability?) and then ask "how would I test such an app for _____?" You could also consider the existing "User Experience" Stack Exchange, they might be able to help in that regard. — corsiKa 27 mins ago

@Phrancis Have you played my tic-tac-toe?
Is this comment grammatically correct?
@molnardenes Excellent question! I've edited my answer and provided a clean way to do this. Although using Loggers, as suggested by 200_success, is also an option - unless you some day might want to save the steps to a list. — Simon André Forsberg 20 secs ago
Especially, is - between "option" and "unless" a good choice?
Are you suggesting that Java loggers can't save the steps to a list?
@Marc-Andre That's why I try to stay away from steam. (I only have one steam game anyway...)
@200_success Hmm... Now that you mention it, they probably can. Although I see no reason for why one would want that option instead of a callback interface if that was the case
Loggers are basically infinitely configurable, and you can even write plugins.
10:18 PM
Can a logger be gíven the a, b and r values without it being as a String?
@200_success lko(), nice one. Clever :)
Yes, loggers can log structured data as well as strings, using Logger.log(Level, String, Object[])
@200_success Which method would you say is preferable if you want it as a list, using a Logger or a callback interface?
Monkevening @rolfl
I think loggers are good enough that you probably don't want to reinvent the wheel. Especially since the original question just had S.o.println(). YAGNI.
And, in any case, loggers will be more flexible than anything you can write from scratch.
It suddenly sounds like loggers can be used for all kinds of interfaces, which does not sound like what they are meant for.
Explain your concern?
10:27 PM
I mean, if loggers can be used as a callback interface for "logging to a List<EuclidesStep>", they can be used for all other callback interfaces as well, although I believe that's not their intended purpose, they should probably only be used for logging to File and to Sysout.
The intention is probably to make it possible to write a plugin to log to a database, for example. You could abuse that extensibility, sure.
@SimonAndréForsberg I think Logback also supports a DB and a TCP/IP socket.
@Donald.McLean Yes, indeed it does.
Not to mention quite a variety of options for files (rolling over, etc).
Yeah, I remember them. I'm using Log4j every now and then...
