Q: Maximum coverage of set with minimum overlap

n0shadowSuppose I have a collection of items, each of which can have up to N labels.

@sineemore All three are from the same author.
I guess some people just like to publish many packages.
 
12:16 PM
Greetings, Programs.
 
@Zeta There is too much of it in modern JavaScript and web development. These days I tend to write mostly static sites/webapps. I saw how the wrong choice of "how much of it must be client side" ruined several projects.
Thankfully our customers are okay with *bloat-free*, static only sites.
 
I've never published a package, but I have mailed some, and received others.
@sineemore Many computer people become enamored with their own cleverness and this leads to all sorts of disasters. I have been guilty of this too.
 
@Donald.McLean, may I print it and hang on our company office door?
 
@sineemore By all means. That is the whole point of "Do the simplest thing that could possibly work." - a reminder that what we do is all about delivering functionality to our users in good time and at reasonable cost.
 
Right.
If you cannot explain in simple words what your code does, you do not know what your code does.

Fortunately for me, my users expect a full up Web Application with all the bells and whistles. Much more fun than static web pages.
 
I don't like GUI. All those pesky users complaining about how it doens't look right, yadda yadda.
 
"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies." quote from quotes.cat-v.org/programming
 
@Mast I'd love for my users to complain. At least then I would get some actual feedback.
 
@Mast Provide your users a DIY GUI kit, where they can arrange the functions as they want :D.
 
@Zeta Code behind? Yea, that may work.

Right. "Here's the library, there's the C interface, have fun and create your perfect UI".

@JDługosz Yes. But it looked like you were mod-pinging someone while you're not a mod here. Figured you mistook this room for the WB general room.
 
Just a perq. I get flags for objectionable content, unlocking rooms etc. across all chat rooms; global powers are intentional so someone is always around, somewhere. Interesting though: how can you tell it was a super-ping? The line looks the same as any other, to me.
 
This looks more like a code review than an SO question. — Christophe Roussy 42 secs ago
 
@JDługosz Chris wasn't here in the past 2 days. So if it was a ping at all, it was a superping.
 
I didn’t know that any @ name that shows up means a ping was successful. I seem to recall the 2 day thing meaning that calls were left on the floor and not signaling; I think I had been asked to ping someone who was stale that way, in the past.
 
Yes, there's such a thing as a stale ping.
Mod's don't stale ping.

But shouldnt I be wary of narrowing conversions and avoid them when possible?
 
2:19 PM
@KarstenKoop This is a good illustration of why broad questions are a bad fit for this site - you've been tempted to start entering into a code review and debugging session with the OP, in a format (tiny comments with partial markdown support) that's really not suited for that. — IMSoP just now
 
@bruglesco Well, you either compute values and then narrow it, or you compute with reduced precision in the first place. Avoiding narrowing does’t mean bringing yourself down to the least common way, it means not using narrower variables in the first place.
BTW, just put this up: codeproject.com/script/Articles/…
I’m trying to post tutorials/whitepaper/notes a few times a week when I’m not on a paying-work deadline. That’s why I’m interested in what he was able to find already (and found lacking) on strides.

@JDługosz thank you for the insight. Should I then use a cast to make truncation explicit or let the narrowing happen implicitly?

@bruglesco I would use my own certainly<float>(x) thing. It just wraps static_cast but can have checking turned on if you need to debug. GSL has narrow and narrow_cast. github.com/isocpp/CppCoreGuidelines/blob/master/…
I’m not sure if the compiler even warns on float — might be a warning level setting.
 
Im not sure either but I use w4 and wX and thats partly the reason I ask

Naturally.
 
@Mast Timeline says off-topic, though
 
@MathiasEttinger Yes, and I can hazard a guess it was for being broken.
But it doesn't say which of the off-topic reasons was picked.
Might have something to do with the off-topic reasons being able to change over time now I think about it...

Oh, "Make it clear that the broken code is not the code for review". Yeah it was the broken code reason
@Mast Do you think the broken close reason changed?
 
Jon Ericson on May 23, 2018

Back when I was a full-time programmer and there was some code someone struggled with, it was a common practice to ask around in cubicle land. Sometimes you’d get lucky and find someone who know the answer right away or knew where to look in the documentation. When Stack Overflow launched, I cultivated a habit of asking and immediately answering questions I’d heard discussed at the office on the site. To this day, I get upvotes on questions like “How can you untar more than one file at a time?” It doesn’t just add to my reputation score—it also feels great to know I’ve helped dozens¹ of strangers. How often can you say that about an hour or so of effort? …

 
@Peilonrayz Before graduation, after graduation and after the recent change were different versions, so at least 2 times, yea.
 
3:13 PM
@Mast The recent one was a wording change due to this meta. And the original also look the same as current ones to me.
I agree the wording has changed, but I don't think the intent has changed, is all
 
@Peilonrayz We went from 3 to more, didn't we? Or did we skip that step?
Anyway, it can be changed.
 
@Mast We've never had more than three, IIRC SE said we arn't allowed without a better reason
 
So it makes sense not to list them in the Timeline unless you somehow deepcopy the reasons into it, which would be database hell.
@Peilonrayz 3 is the maximum pre-graduation, 5 post-graduation.
IIRC
 
@Mast The different versions are stored in the backend 10k. So it'd just mean adding an ID
@Mast I guess that's not the case for us ):

@Peilonrayz Sorry, late ping on the notification...
It was closed as not-working as intended.
Then, someone voted to reopen, putting it in to the reopen review queue, which is where I found it.
 
@rolfl That's fine. I found out you can get instant ones the other day :)
 
In my opinion, the first block of code clearly works, and delivers the intended result. Their attempt at a refactor did not work, so they are looking for other solutiuons.
Which, is "working code, I tried to improve it, but failed... so, I am looking for any/all advice on how to improve it".
 
@rolfl Looks like it was flagged to be close and to open... How strange
 
3:47 PM
And, in case folk would like a link :codereview.stackexchange.com/posts/60366/revisions - it contains the close reason and who voted....
(and the reopen review queue.... codereview.stackexchange.com/review/reopen/97021 )
 
@rolfl I agree it works. However it is not written the way they want. "I want this code to look like this"
What's different between that and "I have this code, but I want this feature"
 
Which methods can throw? And are they really throwing string (presumably std::string but that's not a given)? It does look like you'd benefit from a unit-test framework - most of them can check that expected exceptions are thrown.

Fun times, I might need to make our entire application at work DPI aware
 
4:29 PM
@skiwi That's tough on Windows, but worth it.
 
5:19 PM
@202_accepted It's a C++ application though running for a small part on a proprietary GUI framework and the rest is Windows Forms
(Obviously) we can't require .NET 4.7 and Windows 10 Creators Update (1703) so I think the only option is to implement it by ourselves
 
@skiwi If it's Windows-only, you'd be far better off re-implementing the UI in C#/WPF.
It would take a lot less time, and we've got a bunch of experts here who could hold your hand at first.

CodeReview is for reviewing working code. Since this code doesn't work, it belongs here on StackOverflow. — Remy Lebeau 14 secs ago
 
@DainIronfootIII It's Windows only, but... that's realistically never going to happen
Web is taking more priority anyhow nowadays
 
Yep. Bet it would be easier than making the whole thing DPI aware.
You could even copy/pasta most of your existing logic.
 
5:30 PM
What would be easier? WPF or web?
 
Both are easier than making things DPI aware.
They are about the same, I'd say. They both have their benefits and their gotchas.
TBH, I'd go for web simply because almost nobody wants to install desktop software anymore.
 
I've been looking into it all half day, looks like since Vista you can make it DPI-aware but DPI is determined by the primary monitor and in other situations it will be stretched (System DPI awareness), and since Windows 10 (1703) you have the PerMonitorV2 DPI awareness mode which is the only proper working one
@DainIronfootIII That's the trend I'm seeing, so I'm not sure how much support desktop will get
 
Hey. If you really, really must get DPI awareness, go with the web. The browser provides it to you.
Well, same with WPF. You can get it there from the app too.
 
It's not a short-term fix though, and a month of development time would be short-term definitely
Hmm damn, this might even work... we are hosting our own .NET runtime in our application, and I was wondering how it would work with the DpiChanged event that was introduced in .NET 4.7, but we can just call it by name at runtime :)
 
I'd strongly advise against making it DPI aware. But, /shrug
 
5:34 PM
It's tricky because I don't want to propose an ugly or unmaintainable solution though
Ironically the DPI aware thing came up since I'm implementing an embedded Chromium webbrowser
Which is a WPF control run inside an ElementHost inside our WinForms application of which the .NET runtime is hosted in our C++ application...
 
Oh my gosh.
 
At least my job is fun though in some ways :)
But the matter is quite.. complex
It's almost always technical debt that you encounter though
The application should've been DPI aware since Vista already

@skiwi Actually, no. It shouldn't be DPI aware.
The UI system you use should handle that for you.

@RMunroe Wut?
 
@Mast Yeah I'm sure, the application should be rendered the same, whether you're on a 1080p screen with 100% scaling or a qHD screen with 125% scaling
Currently on the qHD screen it's either living with blurry fonts because Windows bitmap stretches it, or you have to live with a smaller application and need to manually enlarge some parts and increase the font size
 
6:02 PM
Vectorize the entire thing?
 
@skiwi Umm, you are crazy to try to fix that with DPI awareness...
 
@DainIronfootIII Agreed.
 
I and another developer are using it that way, but now you've got consultants too that switch between a qHD screen and a full hd screen and then they would need to use that workaround every time if they don't want blurry fonts
@DainIronfootIII Bitmap scaling with blurry fonts is not an option
 
Still smells like fixing the wrong problem the wrong way.
A double XY problem.
 
Like I said, most, and certainly modern, UI systems handle that for you.
 
6:03 PM
(XY)^2
 
@skiwi What the heck are you displaying fonts in bitmaps for?
Use bloody raw text, and Windows will scale it for you.
 
Let the viewer handle the view.
 
@CaptainObvious No.
 
@CaptainObvious no - #authorship
 
6:04 PM
@DainIronfootIII That is the issue, Windows does not magically work
 
It does with fonts displayed as fonts.
 
possible answer invalidation by Sander on question by Sander: codereview.stackexchange.com/posts/195024/revisions
 
Don't display text in any picture type. Ever.
 
If you're on anything higher than 100% scaling in Windows 10 and your application is not DPI aware (the default) then Windows will bitmap scale it automatically
 
@SamOnela Thanks for the heads up, nailed it.
 
6:06 PM
@skiwi Actually, fonts have built-in support for different sizes that Windows knows to use.
And if your font doesn't support that, then switch to a sensible font.
 
> DPI unaware

DPI unaware applications render as if the screen that they are on has a DPI value of 96. Whenever these applications are run on a screen with a display scale greater than 100% (> 96 DPI), Windows will stretch the application bitmap to the expected physical size, although this results in the application being blurry.
Read msdn.microsoft.com/en-us/library/windows/desktop/… if you don't believe it, I read the whole thing already
 
@Duga Doesn't fix the question, but the question shouldn't have been answered anyway.
 
The world isn't only built around frameworks that know what to do, unfortunately
 
Look. This is part of my job. We have to be scalable for accessibility requirements.
Windows does this automatically if you do it right. And doing it right isn't DPI-awareness.
 
There is literally no other option than setting the correct DPI awareness level, if you don't set it, then Windows will bitmap stretch
Now maybe the GUI framework you are using will do this for you, that's nice, but in my case it doesn't
 
6:09 PM
In that case, the correct option is to switch frameworks.
 
The correct option is to implement DPI awareness, how you achieve that is another question
 
The obvious question now is: what framework is skiwi using and what framework is Dain using.
 
I've used WinForms, WPF, and web.
 
What I'm saying is that there is no room for a major desktop GUI overhaul, so my options are limited
 
@skiwi Quick question: do you have the AutoScaleMode property / whatever that Windows Forms has?
 
6:10 PM
@skiwi Even if the alternative is more work?
 
@skiwi DPI awareness is certainly a major GUI overhaul.
 
I ask because there's a Stack Overflow question with some insight (no idea if it helps):

Q: Windows Forms DPI scaling

Bartosz Karpiński My application looks good with 100% DPI setting, but when user selects different (125% or 150%) words don't fit in containers. I tried to fix this with solution I found here: Detect windows font size (100%, 125%, 150%) which is: this.AutoScaleMode = AutoScaleMode.Dpi; It fixed 150% setting (...

 
@DainIronfootIII I disagree partly, it surely will take lots of time, but we have tons of third party components that only work with WinForms and maybe even don't have WPF, UWP or web variants
 
It's for C# / Windows Forms, so it probably doesn't help much, but might point you in the right (or a more helpful) direction?
 
So in order to change to WPF for example we might do it somewhat faster than a DPI overhaul, but then we'll need to launch six other projects to find new components for parts where there is only WinForms support
 
6:11 PM
@skiwi I think WinForms can already do it.
 
So, WinForms has limited support for it, WPF does it good, and Web does it good when done right.
 
I know the feeling, having to stick to something old because otherwise crap breaks and you have to re-write many programs is awful.
 
@202_accepted I'm not sure, I'll need to look into it definitely, I'm trying to find the path of least resistance
 
@skiwi This might help get you part of the way there, and part is better than none. ;)
 
@skiwi If you provide a generic description of the components, it might be built in to WPF.
 
6:13 PM
@DainIronfootIII We are already moving to web though, so that will be the next big thing and another desktop GUI framework is not going to happen
 
@skiwi Then cut your losses on this and do it right on the web.
 
@DainIronfootIII PDF Viewer? :)

Q: Add a PDF viewer to a WPF application

someone2088I am new to WPF, and am trying to add a PDF viewer to my WPF application, but can't seem to work out how to do it... I have tried following a couple of tutorials/ examples that I have found online, but they don't seem to work for me for varying reasons... For example, I tried following the tutor...

Couple dozen options out there for the picking.
 
@DainIronfootIII That's WPF. We talk Web.
 
@DainIronfootIII There's no time for that, will take years to get everything converted, and right now (for a while already) we're using the built-in WinForms webbrowser which is a piece of .. and can break down at any time, hence we are moving to embedding Chromium

@Mast It's definitely an XYZOmega problem, that I won't disagree it, but it's not as if we have a lot of other options... The WinForms built-in webbrowser is terrible, we need to replace that, Chromium embedded is a very good (and one of the only) options, the WinForms variant however has major showstopping issues (I'd need to get info tomorrow on why exactly) and therefore we need to use the WPF variant in an ElementHost (hosted inside WinForms)
But the WPF Chromium embedded browser requires that your application is DPI aware, so now we need to implement DPI awareness
 
Context, good.
I love context.
 
@skiwi Talk to Mat. We've dealt with this in Rubberduck.
 
I did a trial run of making our application DPI aware but then not actually resizing things, everything worked together nicely, but now we need to use workarounds to increase some parts of the program and the font size, those were already existing options in the program
 
6:19 PM
Or maybe we haven't and should :)
 
But then colleagues who switch between monitors a lot get annoyed (and rightfully), because they would need to change their workaround everytime they switch display/scaling factor
 
Switching monitors screws things up, yea, that's not an application problem IMO.
But I feel what you're getting at.
Tough cookie.
 
To be fair, ever since I got my qHD screen at work I've been putting my application into system DPI awareness mode via the properties and using the above mentioned workaround, but as a developer I barely move screens so it worked for me, even though I suggested the GUI guru to change it
(I absolutely could not live with blurry fonts)
However I may have become the GUI guru now..
Or at least partly ^^ I don't have the deciding factor
Basically it's too much legacy and technical debt
 
Sometimes you just gotta work around it.
Everything at my workplace is legacy, I was offered a new job, and as part of the agreement for me to stay I mandated that they allow me to use the entirety of Q3 for legacy rebuild.
 
We have a C++ GUI framework as well that was built around 1995 which still hosts 3 important views, we're thinking about getting rid of that, but won't be easy
Redesigning them in another GUI framework is quite frankly not an option though, looks like it will be web, the question is who has time for that somewhen, lot sof things to do
Ironically enough web is proving to be the most stable platform
As long as you stay away from those fancy Javascript libraries ;)
Definitely not saying that they're bad things, but I think if your application needs to survive 10 years that the libraries won't do you any good in the end
I'm almost feeling like a coworker now who isn't fond at all of third-party libraries, I guess he may be right
Except I have high hopes on open-source third-party libraries, save time now when implementing something and then still have the ability to fix it later down the line
 
6:30 PM
@skiwi Good luck.
 
I'm voting to close this question as off-topic because questions about improving functioning code belong on Code ReviewMichael 40 secs ago
 
I'd still stay away from them.
I use jQuery (most people say I don't need it) and underscore.
 
We have developed almost all of our frameworks in-house, but I suppose that's what happens when you start developing and need a database and there's no SQL around yet
 
@skiwi That's me. I avoid anything that I can.
I only use third-party libraries when they do things really well, or provide something that I don't have the expertise to create. (I.e. d3.js, iTextSharp, etc.)
 
There's things like webbrowsers or PDF viewers that you can't get around though
Working more on GUI makes me want to work on a web-based client even more
 
6:34 PM
Web is no cakewalk either.
 
We've also been working on a Xamarin-based app for a short while, but recently thinking about turning it into a progressive web app, I'm a little bit skeptical, but so far I can't find a reason why it won't work
 
You run into things like "shoot, this font isn't available on ____" or "dammit, this CSS class doesn't work in Safari."
 
(And neither can my coworkers)
If most issues are related to styling then we can live with that, first need to make the bigger picture work
 
JavaScript between browsers isn't easy, either.
IE, Safari and FF/Chrome/Opera all do things just slightly differently.
Now, the big stuff works between them, and jQuery handles a LOT of the interoperability.
 
Tell that to @Phrancis.
I've tried, but he won't listen :)
 
6:40 PM
@Michael I think we need to clarify whether the code works or not on its own first, if it doesn't work on its own then it's offtopic on Code Review; otherwise, it might be on topic. — Thomas Ward 47 secs ago
 
If we get the embedded browser working we can transition gradually from Windows to Web though as you can call back into the hosting application from the browser

@202_accepted Oh don't forget Edge. Did you know they have a mobile browser now? ;)
 
@Phrancis Yeah they keep telling me to put that crap on my phone.
 
7:34 PM
@Phrancis My family likes it for their iOS phone.
It's a lot better on my WP device than on desktop.
I dislike Edge's JS. The HTML renderer is great. The JS quirks, less so.
For example, when you remove the focused element from the DOM.
FF/Chrome either move focus to the previous focusable node or the previous focused node (I forget which). Edge removes focus from the page entirely, and when you press TAB, it sets it to the first focusable node on the page.
Or rather did a year ago. Haven't retested this since I got updated.
 
Oh.. there's still a Windows 10 feature update pending, I'm not looking forward to installing it

@skiwi I suggest to install it while you're at work. Or on a holiday. Well, when you don't need your PC for several hours.
 
@CaptainObvious I can't remember what the consensus is on TLE questions - should it be deemed not working?
 
I swear I'm going to kill and deinstall Windows one day... I'm gaming and it switches me away from full-screen to show an "you need to install important updates!" prompt, and the prompt doesn't even have a damn close button
 
@SamOnela consensus is that TLE is k, so long as the code doesn't need to work on unreasonably large inputs and demonstrably works for smaller inputs that the ones presented in the question
 
okay that is what I thought
but is 5000 rows with 5000 chars unreasonably large?
I presume many would say Yes
