That said, I suppose that some teams will be hoping that applying a consistent style will keep people from doing dumb things. It's an easy thing to lint for and be sure it won't bite you. I'll just say that it's not a substitute for real code reviews, and it's important not to turn good practice into cargo culting. — johncip 10 secs ago

9:49 AM
@SimonForsberg If I had to guess, I’d say because the description don't even try to explain what the code is doing?
@MathiasEttinger Doesn't the title says what needs to be said?
"Lacks concrete context", which links to this is not for "Lacks description of what the code is doing"
@SimonForsberg Right misread "Unclear what you’re asking" in a hurry.
@MathiasEttinger Seems like a lot of people misread it that way when closing a question.
The title doesn't say much either, it seems to be a calculator, but arithmetic is broader than that
@SimonForsberg Yeah, I always found having the two confusing, but I try to stick to Unclear->missing description; Lacks context->missing code

@MathiasEttinger Good, that's exactly the way you're supposed to VTC :)
@SimonForsberg We've had two metas about this, but it seems a certain user doesn't want to follow that, and is making a trend not to.
Yes, I am aware...
@Peilonrayz Doesn't mean everyone else has to follow either.
@SimonForsberg Yeah, those answers don't make the square fill to the rect. :(
@MathiasEttinger It's been a year since those questions. It's also easier for people to copy other peoples close reasons when picking, and this makes you build an incorrect pattern match. We can say the same thing over and over, but it'll never be as strong as constantly picking the wrong option every day.

> This square can also change dynamically and this approach doesn't resize the square
@Peilonrayz The resize-component I added in my test on the about page isn't meant to be used later, but of course the square could change dynamically because of the browser window being resized
@SimonForsberg Yeah if the browser window changes then it's basically just my question with a bunch of padding (with information in it), and so it is resizable. Never mind you editing the flex directions :)

@SimonForsberg Got it working 100% in Chrome using the experimental ResizeObserver. Found from this SO question. I've pushed to peilon's-nonsense for you to see. :)
@Peilonrayz Cool, I will take a look after work
How much does it work in other browsers? 50% 70% ? :P
Dynamic resize doesn't work because ResizeObserver doesn't exist in them. Using a polyfill should be fine, or using the top answer from the SO question :)
Initial resize should work, or you'll just need to add this.updateMapRect(); before the ResizeObserver().
@Peilonrayz I think I might be able to solve the resize things with some Vue magic.
@Peilonrayz Why the display: none; on the .selectors ?

@SimonForsberg If you don't then you have a ton of whitespace below the map. (As it duplicates the size of the map below .field-views.)

@Peilonrayz Ok, then I guess I'll just have to put those selector-elements inside the other .field-views

2:20 PM
@SimonForsberg That's because UWYA is not intuitive here either.
Making close reasons intuitive is hard.
For example, why isn't a description part of the context? Try explaining that to new users, it's not easy.
This, of-course, can all be solved by leaving a specific enough comment explaining what's wrong with it regardless of the close reason used.
Which is cumbersome at times, but not hard.
@Mast Exactly, which is one of the reasons why I prefer comments, and why I am encouraging others to do so as well.
@Mast Three clicks if you have the auto-comment script.
@Mast By "not intuitive" you mean for new people to the site?
@SimonForsberg If you have enough auto-comments to make them specific enough again, yes.
It's on my to-do list, somewhere. Been there for a while...
My to-do list is about as long as @skiwi his list of tabs.
@SimonForsberg No offense/disrespect meant, but I honestly think the "auto comment" script (and any argument for it) is a bit of rubbish.
@Mast 1156 items on your most important todo list?
2:31 PM
@Peilonrayz Primarily, but even for regular users.
1. It's not mentioned anywhere on the site except in a couple Meta posts and such.
2. It's not exactly "universal" -- I can't put it on my phone / tablet.
3. It's not always trivial to setup, and with browser security boundaries and settings changing all-the-time, is somewhat unreliable.
yea, power users could really use builtin auto-comments
@Mast I guess changing from "Lacks concrete context" to "Lacks concrete code" would be enough to 'fix' this? Makes it explicit about code, rather than 'context'. I don't think we'd have this issue if we didn't have that title.
@Vogel612 That would be a much better solution, IMHO.
le sigh :)
2:34 PM
@202_accepted All true.
preferrably accessible with proper keyboard nav
@Peilonrayz That's not a bad idea.
@Peilonrayz that close reason is not about lacking code alone though
@Vogel612 If it's hidden behind a link too IIRC
it's also intended to be applicable for code-dumps
2:35 PM
Yes, the commit is already in a code review system Gerrit! — xSavitar 10 secs ago
@202_accepted I especially agree about point 3, it's annoying when you have to copy-paste your old auto-comments when it has updated. However, point 1 and 2 is not really any argument against using it when you have the possibility to do so.
No, but it is primarily and abused a lot for the rest. Sometimes with good reason though.
It's all screwed up really, even though we've debated this ad infinitum already.
@Vogel612 Which is why it's unintuitive that it shouldn't be used for questions lacking description.
@Peilonrayz I like that idea
@Vogel612 code-dumps are not mentioned in codereview.meta.stackexchange.com/a/3652/31562
2:36 PM
sometimes my memory is great, sometimes it does this to me ...
@SimonForsberg I do 95% of my SE from my phone or tablet, particularly the SE / SO Apps. There's no ability for me to use the auto-comment script with those, for reason 2 particularly. As a result, I have to come up with my comments all-on-my-own, or maintain an Evernote or something with them in it. (So, as a result, I don't bother using it.)
@Mast It's not meant for code-dumps
@202_accepted Yeah that seems annoying. I never use SE from my phone.
@SimonForsberg Unfortunately, these-days I'm quite-frequently mobile. :/
I have a Windows phone, except for chat most of SE doesn't even work on it.
@Mast I replaced mine a year-and-a-half ago, when they sunset the program.

Yeah, it's super frustrating because he texts me "our professor said to do <x>", and I'm like "Oh FFS that's the complete opposite of what you should be doing." I mean, I don't know python all that well, but I still know the basics.
His professor likes to say that "PEP-8 doesn't matter in the real world", which fine, whatever, to each their own, but if my friend wants to follow the PEP-8 guidelines because they're the de-facto standard, let him.
Welcome, Pat. Because you have a problem with your code, you are asking at the correct site. But, since you are new, I will inform you that when your code is complete and tested, you can post it at our Code Review sister site and get feedback on how you might improve it. It can be very helpful. — Mawg 50 secs ago
@202_accepted A lot of things doesn't seem to matter in the real world, does that mean that we should just give up on promoting good code quality standards?
@SimonForsberg That was my point. Yeah, sure, you can write Python without PEP-8 (and plenty of people do), but a lot of us follow it because it helps create a consistent experience, so you should probably advise students to do the same.

@202_accepted You got to keep some standard to keep your code base sane.
@202_accepted Back when I was at school, I wasn't allowed to use JSON because "it's not used in the real world"...
@Peilonrayz There was a time where, when building a webpage, you didn't use JavaScript if you didn't have to. It was too expensive bandwith-wise, slowed down your loading time and was too much error-prone.
Some advice isn't wrong, but outdated.
@Mast Unfortunately, that's not outdated.
I work with JS enough to know.
@Mast I can't imagine a time where anyone said "don't use JSON", only a time when it didn't exist.
And yes, we still have to support PoS (technically, that's point-of-sale, but read it how you like) machines where JS execution is a serious factor in performance.

@Duga Converted an answer to a comment
Voting to close as off topic, not working as intended, because the stated problem is "The new list should be made by splicing together the nodes of the first two lists" but the code is not splicing the lists together (it makes copies). And there's a bad bug. — 1201ProgramAlarm 17 hours ago
Can any C-person tell me if it's a big issue or not that it's making copies instead of splicing lists together?
5:51 PM
@SimonForsberg Well, in short it simply means the code does something else than the problem statement asks for.
It's like using the wrong sort method.
If the problem asks for a bubble sort and you write a selection sort, the code does not work as intended.
@Mast Does something else, or in a different way?
Sounds like different way
@Mast You have a point there
What does "splicing together" mean anyway?
That's very context dependent, but with linked lists, it's basically a relink.
Like a transfer.
But the whole point of a splice is not needing copies.
I voted with unclear what you are asking because at the time of my vote thats what it had been for me.
@SimonForsberg ^^^
@Heslacher Ah thanks, I didn't check who VTC'd for what
@Mast So you merge the two lists into each other, modifying one of the existing ones?
6:06 PM
Splicing itself is more generic than that, but think of it as moving the pointer instead of copying the data.
@Duga should we let t3chb0t know that another user has an avatar with the same character?? (not that he/she has an exclusive right to use it)

@Peilonrayz I had an issue with the view not updating on first load so now I also call the updateMapRect method when component is mounted
@SimonForsberg Makes sense, is everything else working?
@Peilonrayz Looks like it so far, gonna test it on other devices to make sure shortly. I haven't tested many different browsers but I assume you have tested a few at least.
@SimonForsberg Hahaha, very nice
@SimonForsberg I'll take care of that now, you all can make it a reference question or whatever.
@puzzlepiece87 Perfect!
@SimonForsberg I mostly just tested on Firefox, and moved the viewport around a lot. I don't think there's a reason for it to not work on the other browsers, except maybe IE.

Q: Given CR's question title policy, how to title a second question about the same program?

puzzlepiece87Originally asked in 2nd Monitor If we're asking a second CR question involving the same software, is it acceptable to give it nearly the same title? What is best practice for naming these questions?

Feel free to chime in with your above answers or make a community wiki answer or whatever
@SimonForsberg I bet you'll get a lot of smiles/upvotes for including that sequence in your answer.
@Peilonrayz I don't care much about IE anyway
@puzzlepiece87 That's the plan

A: Given CR's question title policy, how to title a second question about the same program?

Simon ForsbergCreating different titles for follow-ups is difficult, so most follow-up questions tend to have very similar titles which is perfectly fine. Some options for naming a follow-up question is: XYZ Program v2 Follow-up to XYZ Program XYZ Program continued XYZ Program - follow-up If you want to be...

@SimonForsberg you have the announcer and booster badges but do you care about going for the publicist badge?
@SᴀᴍOnᴇᴌᴀ Somehow I tend to get those kind of badges every now and then, for very weird questions that I sometimes don't even remember that I have shared.
Also, I don't think you can get those badges by sharing links internally within Stack Exchange
I don't think a chat link will give me progress towards them, or a meta link
8:02 PM
oh so your meta answer counts as "internally within Stack Exchange" as well?
Like this: stackoverflow.com/q/28662058/1310566 I got an announcer badge for that on February 11. It was a long time ago since I shared that question at my work, and now I don't even work there anymore
@SᴀᴍOnᴇᴌᴀ I think it counts as internal yes
Actually, maybe I didn't share it at work, maybe internal links do count...
Or someone copied the link, posted it somewhere, and then I get the credit for sharing it :D
@SimonForsberg Any linking counts IIRC.
If you share it, and someone clicks it, you get credit.
Q: Formatting time delta

Mantas KandrataviciusQuite often, I find myself measuring how long some part of my code takes to complete. I normally do that by storing current time using time.time() and then subtracting time after the code is done. This normally gives me a float that I can then format and print for debugging purposes. This is the...

@202_accepted Only one way to find out: Could I get 25 different IPs to click on this ? :)
@SimonForsberg One down
Question: does it count if I copy/paste the link?
Oh crap, it's 25 needed for bronze, not 10
@202_accepted As long as it ends with /31562 I get the credit, as that's my user id.
If copy/paste counts, there's two.
@SimonForsberg I have a server farm with over 200 IP's in it, I could loop through all of them and ping it...:P
@202_accepted lol
Alright, only used 1 from the farm.
Wonder if I can get more allocated to me...
8:14 PM
@202_accepted When you get a link from SE it usually looks something like this: [site].stackexchange.com/[qa]/<postid>/<userid>/
sooo it's not any linking
because only the visits with a userid are attributed to you.
@Vogel612 I figured, didn't know if they checked that it came from a Referrer or not, though.
@SimonForsberg If you know where to look, I'm listed in the ARIN WHOIS Database.

possible answer invalidation by khashashin on question by khashashin: codereview.stackexchange.com/posts/214161/revisions
@Duga Hmm.... 1) Doesn't that say that the answers are slower then the OP? 2) Not sure if it counts as invalidation or not.... @Vogel612?
Sorry but Stackoverflow is not a code review service, IMHO this code has some issues and we can only try to guess. The OP did not provide yet a Minimal, Complere and Verifiable example. stackoverflow.com/help/mcvedparoli 59 secs ago
yes it says that. I'm tempted to rollback for the atrocious orthography and self-deprecation. Also a performance test without the used code presented is ... probably bollocks?
well it says that Matthias' answer is marginally faster and both are using 99% less function calls
which is kinda breaking my suspension of disbelief.
I don't know that I'd trust that "benchmarking", it doesn't explain what a "Function Call" is...
@Vogel612 Oh, few function calls is a good thing?
8:40 PM
if you get the same result in fewer function calls I'd say that's a good thing, yes....
@Vogel612 Is that what happened, though? Or was it a "timed" test, and they counted how many times it could be run in that period?
I was first thinking that it tried to do as many function calls as possible in the same amount of time
@202_accepted you're reading the same post as I am right?
Rollback as "unclear what you are editing"?
I dunno
8:42 PM
@Vogel612 I think so, I don't trust the "benchmark" what-so-ever, I'd like to see the technique used and what definitions are at play.
The times are within 500ms of each other, while the "numbers" are several orders-of-magnitude different.
It's going to be better if I say nothing now...
Different topic: I'm trying to move a REST service from being an eclipse plugin to being a webapp
Can someone add some comment to the question perhaps?
how in the world does RESTEasy work?
~sigh. Maven, you don't get to decide that there is a compilation error and then there isn't one from one moment to the next
@Vogel612 Never used it, these days my favorite REST server is Javalin - especially wonderful if you can use Kotlin

Q: Dynamically Generating XML Deserialization Classes / Code: Part I, Reading

@SᴀᴍOnᴇᴌᴀ I don't want to scroll, figured you didn't want to either :)
I have been using the PageDown key more lately
@Vogel612 You using some kind of byteassist library? Hibernate maybe? Or something else?
@SᴀᴍOnᴇᴌᴀ Figured you didn't want to do that either
well there should be a hibernate somewhere on the classpath, but I'm not touching jars that I depend on through maven
@Vogel612 You sure about that? Because otherwise I'm not sure how that error message got there
9:37 PM
I actually set up proper maven dependency myself within the last 72 hours and I'm the only one working on that state, sooo...
yes I'm sure
yea, I assume the module-info.class (which is java9 stuff) is just tripping tomcat8 when it expected a language-level 8 war
probably so, yes
I'll try downgrading that specific dependency to see whether it keeps blowing up
You should be able to get rid of all the module-info.class files I think somehow

I'm not gonna start rewriting all jars I get from maven
I mean somewhat more automatically than that, like with some Maven configuration
I already have my sourcelevel on 1.8. If that's not a hint for maven I highly doubt there's another one, honestly

Sounds like you've made quite a lot of progress
Out of curiousity, what was the fix?
Q: Singleton service class with inheritance

Jacob StammThere is a service class (ProposalPdfService) in one of our assemblies that has implementation logic specific to that app's assembly. Previously (and, I believe, erroneously) I treated it as a quasi-singleton by making it and all its members static, but I refactored it to use the singleton patter...

@SimonForsberg use a newer tomcat version :D
lol, yeah well that works too

Sounds like the best solution to upgrade tbh
we're using Jersey as well, sooo ...
The whole project is gaffa-tape, spit and snakeoil
So you're using both Jersey and Tomcat? You haven't considered using Jetty as well while you're at it?
How come you are working at this hour though?
~meaning-havy sigh
mostly because I was sick last week and didn't get to working as much as I wanted and because I'm free to work whenever I damn well please
benefits of a student job that I can work from home
We're configuring jersey when the application is started. We're also using Apache Camel, OSGI and a handful of other things that are ... quite dubious IMNSHO
there is some stuff around jersey-min and jersey-all. I should actually ask my boss whether they had that in the back of their head when they defined tomcat as the new host instead of eclipse
