Q: Please check/ comment on my code

This is the first bit of code I've done so just after some comments/ feedback on it; MONTHS = 'JANFEBMARAPRMAYJUNJULAUGSEPOCTNOVDEC'; //months document.write ('<h1>Introduce Yourself</h1><hr />'); var userName = ''; //create username variable userName = prompt('Enter your First Name','Alex'); //...

javascript

Mat's Mug

what changed? the reference couldn't possibly have changed. its mutable properties might though - the copy of the object reference being passed does point to the same object after all

Lars H

When You Pass an object You just pass a Pointer to a memorylocation.

And thats true even when you pass it ByRef'

Mat's Mug

indeed. the only difference is whether the method receiving that parameter can (ByRef) or can't (ByVal) reassign that pointer to point elsewhere

Lars H

12:06 AM

Well then You agree!

Mat's Mug

lol

Lars H

The values in the Object can be changed !

I Still have to try your example !

Mat's Mug

of course the values in the object can be changed, but that's not what ByRef/ByVal do...

- passing a reference by value (changes to fields/properties of the ref-type are visible to the caller, but reassigning the ref-type to a new/different object is not visible)
- passing a reference by reference (changes to fields/properties, and reassigning the reference are visible to the caller)

A: How to 'do' ByVal in C#

Parameters in C# are, by default passed by value. There is no modifier to make this explicit, but if you add ref / out the parameter is by-reference. The usual confusion here is the difference between: passing a value-type by value (changes to the value-type are not visible to the caller, but ...

^^ this answer explains it pretty well

@LarsH I took a string as an example specifically because it's an immutable reference type, which makes the behavior more obvious :)

Lars H

As you said String is a special case !

Because it is immutable !

Jeroen Vannevel

@LarsH: show an example then that demonstrates what you believe it means

get rid of the confusion

Lars H

12:19 AM

Well its just What I said Before ! If I pass A table "ByVal" and then change the rows in the Table ! The Rows will be Changed !

Mat's Mug

The rows aren't the table

Jeroen Vannevel

that's different

besides, you're passing the reference by value

you can't reassign it, but you can modify its properties

Lars H

Well then we are on the same page !

Jeroen Vannevel

If you use ref, you can also reassign it

Lars H

Yes.

We seems to be in agreement !

Jeroen Vannevel

12:22 AM

You can't tell me what I seem like!

Mat's Mug

but it does not mean that an object is passed by reference no matter what!

@JeroenVannevel lol

Jeroen Vannevel

If I understand this endless debate, it's like this:

value types are passed by value. This means all structs. You can't reassign their properties nor the actual reference to change the original

reference types (classes, interfaces) are passed by reference by value. You can't change the reference but you can change their properties

ref and out pass the reference by reference: changes to properties and the actual reference are propagated to the original reference

Lars H

There are so many out there that doesn't get that the content of an Object can be changed even iuf You pass it ByValue

Mat's Mug

var object1 = new Something();
DoSomething(ref object1);

void DoSomething(ref object obj)
{
    obj = new Something(); // caller gets the new reference
}

void DoSomething(object obj)
{
    obj = new Something(); // caller does not get the new reference
}

Lars H

But personally I have a problem ;

@JeroenVannevel why do commas suck?

Jeroen Vannevel

I don't like them here

Maybe it's a remnant from my 5 minutes dabbling with CSS?

Mat's Mug

@LarsH what's the problem?

Jeroen Vannevel

I removed the commas. At night the codebase becomes mine and mine alone so it'll have to follow my rules

python lisp closure

Lars H

ForEach over IEnumerable generates more IL-code !

Mat's Mug

ok, but then enumerating the IEnumerable with ToList() prior to looping makes you iterate it twice... so....

Lars H

12:42 AM

Well what I understand You have to do an overload for whatever You want to loop over!

ToList() is just bad especially in a loop.

Mat's Mug

I mean before entering the loop. so that you iterate a List<T> instead of an IEnumerable<T>

but I don't see a point in doing that

Lars H

No but still ! I just read that it was so beatifull with IEnumerable and then I find out that when Writing performant code You shouldn't use it.

So You will have to have two types of codereview !

Jeroen Vannevel

@Mat'sMug: I manually replace two pivot items with another page. If I try to interact with the page too fast (scroll to the next one or just click on a button too fast), it crashes "value cannot be null". If I wait a few seconds, it works just fine

any experience?

@LarsH: Take everything in that book with a grain of salt. It focuses on extreme performance measures that you will never need 99% of the time. It's nice to know as a background but it should never dictate your code unless you do it for a very good reason (aka: you're building the next atomclock or whatever)

rolfl

So, my son, gifted, but not all this time....

Lars H

Well I often have to make measures because I write Components that other use and very often I have to skip LINQ but I did't know about ForEach over IEnumerable

Jeroen Vannevel

@Mat'sMug: nevermind, think I found the culprit

Well that's a fun one

If you click the calendar the first time, it gives you a correct notification you're not logged in

if you click the calendar again, it logs you in

I don't even know where it gets the credentials from

literally the entire event handler is this

    private async void OnCalendarButtonClicked(object sender, RoutedEventArgs e)
    {
        if (Session.Instance.IsLoggedIn)
        {
            Frame.Navigate(typeof(MainPage), 1);
        }
        else
        {
            await new MessageDialog("De kalender is enkel beschikbaar wanneer u aangemeld bent.").ShowAsync();
        }
    }

ah, the joys of non-awaited asynchronous methods

looks like the saving of credentials on the phone does in fact work

but since it initializes from the constructor, you can't await it

so while the session is busy logging in, the startpage has already decided nobody is logged in, so it gives an error message

but by the next time you click, that unawaitable login request succeeded so it lets you pass right into the logged in view

Most people posting questions here have less than a few years experience. The vast majority.

Code that works for the given use-case, and very little else.

What I call 'brittle' code. Looks good, even smells good, but put it under pressure, or try to make it take some weight.... or bend a bit for a enw task, and it shatters.

Q: Making kexec reboots less painful

kexec is a way for a Linux kernel to directly boot another Linux kernel without going through the usual BIOS startup sequence, which can take several minutes on enterprise servers.

Q: CPU friendly infinite text scroller - velocity

I've done some research today and read a lot about JavaScript performance. I learned that animating using the transform: translate makes a use of the GPU, hence reducing the CPU usage. I've also read about velocity.js which seems to be a replacement for $.animate(). I've tried to combine these t...

Wow! You put a lot of work into this. Thank you for sharing. I have some suggestions for you to consider. Add setlocal to the top of your script. This script uses a lot of variables. After you exit, they're still hanging around, junking up your environment, potentially causing problems for...

Q: Monitor Downloads folder and sort files as they are downloaded

I have written my first shell script that uses inotify-tools to monitor my Downloads directory. What i intend to do with the script is that, as soon as a file is downloaded, it moves that file to a folder named after its extension. For example: if it is test.pdf it will be moved to a folder named...

That one is one vote short: codereview.stackexchange.com/questions/71993/… ;)

janos

most of us here probably already upvoted it though ;)

rolfl

@Mat'sMug I've been 1-vote-short of a guru for about 3 months now.....

I presume that's because all the regulars have voted, and the visibility is low.

Also, I find when I go through 1vote short, at least 2/3 of the times there are badges which require >= 10 votes, I have voted for already.

1-vote short has created artificial steps in Code Review vote patterns.

@rolfl lol nice graph :)

Mat's Mug

What's that chart showing exactly?

rolfl

I had to use a logarithmic scale on the left.....

On the X axis is the post score.

on the Y axis is the count of posts with that score.

janos

lol

rolfl

two series, one is questions, the other is answers.

Mat's Mug

Ah

Well that's a nice one

rolfl

5:04 PM

I made the count a logarithmic scale otherwise the scale is too large to see the blips.

There are some extreme outliers on the + score side, so I have excluded scores where there's only 1 post with that score.

Stack overflow is more entertaining ;-) data.stackexchange.com/stackoverflow/query/257875/…

RubberDuck

Interesting graph Guru @rolfl

Oh wow!

People just don't vote there do they? Drives me nuts. 4 or 5 answers on a question. 0 votes.

If you think it's worth your time to answer, isn't it good enough for an upvote?

janos

when looking at Score < 100, no outliers like here on CR

data.stackexchange.com/stackoverflow/query/257880/…

yeah that's a bit troubling

Mat's Mug

Maybe CR needs a meta-reminder?

Jamal

@RubberDuck Ugh, tell me about it. One reason why I don't bother trying to find anything else to answer on SO.

rolfl

OK, tidied up the query (@janos - it allows min/max filtering on the score range now): data.stackexchange.com/codereview/query/257875/…

@Mat'sMug About voting?

A 'Tis the season for giving' thing?

janos

5:19 PM

nice!

I think it's not so great that we have these anomalies around 9, 24, 39

but at least we're not alone, serverfault seems to have similar too:

data.stackexchange.com/serverfault/query/257875/…

programmers too:

data.stackexchange.com/programmers/query/257875/…

so that's a bit of a relief :)

rolfl

@janos Interesting, they have a dip in questions at 39, and there's no 40 badge for questions

RubberDuck

Natural phenomenon?

janos

hm, that's odd

rolfl

It could be a variation just based on volume.

At least on programmers, the difference is in the order of 10 posts total.

janos

do I interpret it correctly that the anomaly (on CR at least) is due to small sample size for these scores?

rolfl

5:34 PM

@janos No, at some points the CR counts are low, but the differences are large... See the actual numbers now in: data.stackexchange.com/codereview/query/257882/…

anything past score 20 on CR is suspect though.

@rolfl why?

The numbers/volumes are too small to draw conclusions from.

Not that the voting is suspect, but, for example, the dip at 39 for answer scores, on CR, is the difference between....

There are 54 votes on that now?!

4@38, 2@39, and 3@40

is the 3 at 40 being just 1 more than 2@39, really an indication of the 1-vote-short being a game changer?

Q: '100' is a magic number

Magic numbers are bad. I totally agree. But there's a magic number I find hard to fix: '100' is a magic number. Consider this code: public double getPercent(double rate) { return rate * 100; } public double getRate(double percent) { return percent / 100; } Sonar will raise 2 vio...

java

I don't think so

I think it's stuff that goes hot that's still the biggest skewer

rolfl

I agree with that, but the one-vote-short is also making a difference

The question is whether 1-vote-short made the 40-score answers 40, or whether it is just noise at that point.

Mat's Mug

Individual voters can still make a difference...

Mat's Mug

We need more voters.

meaning that the small sample sies for those scores make the conclusions suspect.

Hmm... That peak and dip directly correspond to how much time I've spent here. Not saying all of those votes were mine, but I know it was a significant portion of the increase/decrease.

@RubberDuck same with my votes.

@janos If I'm gonna make a fast recovery, I'm gonna need a lot more than one vote!

I don't like being sick, I want to code!

janos

that was not just any one vote ;)

usually there's a lag in the badge deliveries, maybe you haven't seen the significance yet

Simon André Forsberg

oh, you mean this? :)

You've earned the "Good Question" badge (Question score of 25 or more) for "Tool for creating CR questions".
