@Ixrec hey - you know C++ supra well, jah?

I wouldn't go quite that far but I have used it a lot and read a lot about it

Jimmy Hoffa

@Ixrec well to be fair, supra refers to below; not above.

Ixrec

lol

so what did you want to say about C++?

Jimmy Hoffa

13:49

@Ixrec I want someone to tell me there's threading bugs in this:

Q: C++11 version of Windows EventWaitHandle

I don't know C++ at all, but for the heck of it I tossed this together because I was talking with someone about C++ and was given the impression there is absolutely nothing quite like the windows APIs ManualReset and AutoReset EventWaitHandles, so I figured I'd see if I could create one. I think...

I never feel ok about any piece of code I write that no one finds holes in

Ixrec

ah, sorry, I've never done any multithreading

Jimmy Hoffa

balls

I'm sure it's got errors, but I haven't the C++ chops to know where.

Ixrec

> I don't really know well enough how to make a thread to test it's multi-threading off hand in C++ and don't care to try figuring it out.

std::async?

Jimmy Hoffa

@Ixrec Что?

Ixrec

en.cppreference.com/w/cpp/thread/async

you basically just pass it a function and some parameters and it "just works"

(there's some controversy over how the returned future's destructor operates, but that's the only problem I'm aware of)

yeah that code is definitely not something I'm qualified to review

and now I have another flip flop

Lightness Races in Orbit

14:00

and I still haven't solved this race condition

it makes no sense

Jimmy Hoffa

@Ixrec well quit it!

@Ixrec ohh you're referring to how to make a thread? Yeah I could use std::thread I'm sure and it's probably this side of easy to put a sleep in it, followed by it making a notify or whatever just to prove cross-thread-signalling works... but.. eh. Writing that C++ was painful enough, more less writing more

@LightnessRacesinOrbit yes; unless I'm mistaken you didn't identify any bugs for me to fix though?

and nothing responded on my CR.SE post

Jimmy Hoffa

15:27

@LightnessRacesinOrbit thanks for your post! I typically rely on recursion since it's clearer to read, but since it's C/C++ every little inch of performance gets counted so I agree, I should go with a loop there. As for lines being too long, yeah I suppose I could break some of those operations up a touch.

@LightnessRacesinOrbit on another note - do modern C/C++ compilers not have TCO?

thinking about it, that's a prime candidate

ratchet freak

TCO?

Jimmy Hoffa

tail call optimization

Jimmy Hoffa

15:30

It's interesting to see users who are still around

@ratchetfreak yes, but it would make his mention of using a loop over recursion in my function there moot as they'd be identical

it doesn't matter, it just made me curious; do modern C/C++ compilers have TCO?

ratchet freak

an optimizer will put it in

though you can make it explicit

Jimmy Hoffa

92

A: Which, if any, C++ compilers do tail-recursion optimization?

Both the current version of VC++ and GCC do tail call optimizations fairly well and even for mutually recursive calls. I bet the Intel compiler does, too. Letting the compiler do the optimization is straightforward: Just switch on optimization for speed. But you do that anyway, right? ;-) For ...

there we go. @LightnessRacesinOrbit you don't have to worry about stack growth from clean pure recursion anymore

Of course, impure recursion will still require stack swaps

Ixrec

huh, now I have Flip Flop on SO...I can't remember doing anything at all on that site today, other than following a Duga link and upvoting the existing "no don't do that" comment

@LightnessRacesinOrbit just something to think about when you see a clean recursive solution- it may not be expensive as we've been taught to think. You're right though that it should be a loop for those reasons

Lightness Races in Orbit

@JimmyHoffa nothing about teaching - just an intuition

yes, it'll likely be optimised out

I still think it looks wasteful

loops ftw

ratchet freak

yeah the idiom for looped waiting is a actual loop

Jimmy Hoffa

In early days of .NET people had to be explicitly informed NO DAMNED RECURSION - NOT EVER - it's one of the classic trivia questions for .NET interviews "When will an exception not be handled?" - Stack overflow. So for me it feels like a "trained" reflex because it's something .NET folks are demanded to be wary of so much..

We still don't have TCO.. :/ Not reasonably

But screw it, I use recursive solutions all the time anyway. I just make sure never to use one when it would be even close to reasonable that it may run out of stack space.

ratchet freak

you've been doing haskell too much

ffahim

15:43

hello everybody

Jimmy Hoffa

@ratchetfreak recursion is just a lot clearer for a whole class of situations..

> Hi Doctor Nick!

Lightness Races in Orbit

@JimmyHoffa So it's a trained reflex to use recursion because you were taught "no recursion ever"?

ffahim

who is doctor?

Jimmy Hoffa

@LightnessRacesinOrbit no - the opposite is.

> it may not be expensive as we've been taught to think.

culturally .NET folk will hiss and scream at recursion

ffahim

ratchet freak

15:46

tail call recursion vs. explicit loops

ffahim

what is that

Lightness Races in Orbit

5 mins ago, by Jimmy Hoffa

We still don't have TCO.. :/ Not reasonably

So it probably is.

Jimmy Hoffa

@ratchetfreak also - stack space in .NET is the least of the expenses you're paying when running in the .NET runtime. The expense of your whole runtime outweighs most all of the little things you may do - which is why .NET and Java it's pointless to try optimizing out individual operations. It's the big operations you want to avoid - mostly IO stuff.

Lightness Races in Orbit

it's using .NET and Java in the first place you want to avoid

Jimmy Hoffa

:P computers seem to manage just fine with that stuff these days so..

The real time sinks in .NET (and probably Java) are reflection, IO, and GC. These things cost so much more than a new stack that pretty much every little operation you may not need or new stack - so long as they don't add to the reflection, IO, or GC, are going to be completely in the performance noise

Lightness Races in Orbit

15:51

do they

only because people seem to think it's acceptable to be forced into buying an i999 250,000,000GHz septacentacore CPU in order to open a word processor

ratchet freak

applications do tend to get more bloated

Jimmy Hoffa

@LightnessRacesinOrbit yep; I have been working in .NET for years on systems that were quite large with huge amounts of data throughput, and they work just handy dandy. Perhaps C++ would have eeked out more but that would have required a lot more time spent on the code and maintenance and a lot more risk

@LightnessRacesinOrbit to be honest, most .NET devs are terribad...so... yeah. :/ I've worked on large .NET desktop applications that ran famously well, but more often than not I have to correct a bunch of awful crap other people did to get them there..

though to be fair for desktop - I just don't care. It's so irrelevant in my book..

Servers should be doing all of your compute (unless it's like games or something that would require too much network transmission..) and the desktop should be thin client in my book. Specifically, Google and Mozilla have provided us with the thin clients..

Lightness Races in Orbit

ew I forgot you're one of those disgusting "everything shuld be cloud lol" people

Jimmy Hoffa

some things can't get away from needing to be desktop - and at that point, sure use C++ or anything else, it shouldn't matter.

ratchet freak

to bad those thin clients are not so thin anymore

Jimmy Hoffa

15:57

@ratchetfreak true enough.. either way, write your own thin clients for your own applications if need be but really it should just be UI stuff on the desktop..

Ixrec

my impression was that in practice you only run on the server things that absolutely need to be on the server for performance, security, or "that's where the data is" reasons, and all other work is offloaded to the client because there are more clients than servers

though there are a lot of apps where "all other work" arguably is "just UI stuff"

Lightness Races in Orbit

and because latency, and privacy, and security, and convenience, and you can do things better with a real native app than you can in a web browser, and, and, and...

Jimmy Hoffa

@Ixrec that's one approach... I just can't imagine doing important computations without the server being "where the data is", and "where the data can be computed quickly" and "where the data is secure"...

like I said, for desktop apps..use whatever. Who cares. It's a desktop application; bloody meaningless.

Ixrec

I intended to include all of those under "that's where the data is" reasons

Jimmy Hoffa

Desktop applications will never generate the petabytes of data that servers are dealing in; you have to have many many users to get that data which means you're using some kind of centralized server

Lightness Races in Orbit

15:59

I like how I'm taking over the starboard. You're slowly becoming The New Lounge and you don't even realise it...

Jimmy Hoffa

Which is why from my perview, I just don't care about desktop.

Ixrec

user55340

@JimmyHoffa It ruins the expectations of the user experience.

Lightness Races in Orbit

haha a downvote

Jimmy Hoffa

This may be a worthwhile question, but first you have to clarify one really important point: WHY don't you want to use radio buttons? They perform precisely the behaviour you want. To claim you want something else to perform that functionality, you need to give back story as to what you are actually trying to accomplish - and why it needs to be solved in an absolutely non-normative fashion. — Jimmy Hoffa 7 secs ago

If he can edit it or comment so I can edit it and say "I cannot use radio buttons because X, Y, Z, but I need the behaviour for A, B, C, how can I go about providing this UX without ratio buttons?" then we can have a meaningful Q&A

right now though, it's just meaning less and especially given that code-snippet answer..ugh..this is not SO..

Ixrec

16:10

hence I downvoted and VTC'd as unclear

Jimmy Hoffa

@Ixrec I will in ~30. I want to give some time for him to respond so that I might correct it first. If a corrected version is still close vote worthy, I'll correct it then CV..

Ixrec

I generally don't spend enough hours a day on the site for the whole "remember to come back and vote later" thing to be remotely practical

Jimmy Hoffa

@Ixrec totally reasonable.

goddamnit I just got flip flop on programmers

where is that secret hats meta Q I posted..

Ixrec

maybe if the site name changed and all the off-topic "spam" disappeared overnight it would become practical

Jimmy Hoffa

@Ixrec I was arguing for site name change ages ago..

the google rankings hit would be hard but... hell, why do I care?

Ixrec

16:15

I think everyone is now

Jimmy Hoffa

I know

Wish it didn't take so damned long

Ixrec

that's actually an upside, we'd stop showing up in google searches for generic "programming help" or "how to deal with stupid programmers" and other off-topic nonsense

Jimmy Hoffa

Our question rate is ~35/day, that may drop like a stone - resulting in who knows how many participants just stopping showing up...

it could be a very dangerous game

Ixrec

but everyone agrees most of that 35/day is crap

maybe we should try to estimate our non-spam question rate

Jimmy Hoffa

over time question rate would start to rise again, but by then how many answerers had we lost?

@Ixrec good idea

take my SEDE query and filter out closed/deleted Qs

Jimmy Hoffa

That SEDE I posted is ugly nasty bad SQL

but it's forked and reforked and reforked from various other writers..

my whole contribution is basically this line: CONVERT(DATE, DATEADD(day, (DATEDIFF(day, CreationDate, @LastFullDayOfData) % 7), CreationDate)) [Week],

Ixrec

16:31

ah, I see a score > 0 in there too

Jimmy Hoffa

@Ixrec a 0 scored Q still qualifies as one we obviously don't damned well care for (IMO)

Ixrec

hm, yeah that only changes it from 10 a week to 15 a week, not a big change

Jimmy Hoffa

not sure where "35 qs per day" comes from

Ixrec

so whatever I was doing was probably just broken

Jimmy Hoffa

well, the way I'm rolling it includes our dead days in the average

Ixrec

16:33

@JimmyHoffa your first query was showing 100-150 per week, so...ok yeah 35 a day is an overestimate

@JimmyHoffa dead days?

the hat task runs...every five minutes?

Jimmy Hoffa

Ixrec

16:38

@JimmyHoffa so what I'm seeing is our average non-crap questions per day is 1-2

which is...even worse than I guesstimated :/

Jimmy Hoffa

@Ixrec no

Your SQL are the bads

One second

Ixrec

I'm looking at your query, it shows 10-15 acceptable questions per week

Jimmy Hoffa

@Ixrec average per day per week

that shows 227 non-closed questions with a score of >0 in November

what I do see is a fall around September

But, it trends up... arguably until exams.

Ixrec

the trend up at the end is probably the tail of not-yet-closed stuff

Jimmy Hoffa

17:03

@MichaelT I don't understand the cyclical nature of the graph - I remember seeing that in weekly rollups before and trying to scratch my head at it. Is it monthly?

enderland

@MichaelT is that percentages? or absolute numbers

user55340

@enderland absolute.

user55340

Or whatever jimmy's query dumps out.

enderland

Percentages would probably be a more compelling trend than absolutes, because 20/100 questions being good is much worse than 15/30

pretty sure it's absolute, the versions of the query without "acceptable" were giving 100-150

what do you call those charts that show the min/max as a bar with a line in the middle for median?

Box plot

In descriptive statistics, a box plot or boxplot is a convenient way of graphically depicting groups of numerical data through their quartiles. Box plots may also have lines extending vertically from the boxes (whiskers) indicating variability outside the upper and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram. Outliers may be plotted as individual points. Box plots are non-parametric: they display variation in samples of a statistical population without making any assumptions of the underlying statistical distribution. The spacings between the different parts...

sweet, got my wifi modules

Jimmy Hoffa

so, yep.

That excludes weekends

Ixrec

that's a bit depressing

Jimmy Hoffa

not really. 10-20 good questions a day? That's plenty of good content.

Ixrec

I meant the steady decline

Jimmy Hoffa

*30 -> 300-600 good questions a month. That's a lot of content. Imagine wikipedia adding 300-600 pages a month

eh.. you have to look at the era

it doesn't strike me as a steady decline

the first third of that or more is NPR

(I think?)

psr

@JimmyHoffa or just lurking

@Ixrec a decline is to be expected, even

once a question is asked, it does not need to be asked again

This comment: This post would be better if you explained X, Y, Z. comes across as "someone has an idea for a possible enhancement to my post, but it's not needed". This comment: -1: This post would be better if you explained X, Y, Z. comes across as "oh okay I had better make those c...

grumble mumble.. I get boxplots working and then find out I need to use some other library to overlay multiple on the same spot...

and it has a totally different API grumble

Lightness Races in Orbit

did you try a standard API

Jimmy Hoffa

@LightnessRacesinOrbit I will say this, R is fast

now if only they didn't use so much non-english verbiage throughout their APIs

Q: Why can't my program compile under Windows 7 in French?

I'm running Windows 7 French and I'm trying to compile this really basic program, but Visual Studio is being stubborn and refuses to comply. I also tried compiling it with both GCC 4.7 and Clang trunk on Coliru and I get more or less the same errors (output is below the code), though I think Coli...

> ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and none of the bad parts

Lightness Races in Orbit

Rrrrrrr me hearties

Jimmy Hoffa

20:14

because apparently base and lattice graphics is a great terminology to start with for something that people are supposed to use just to create simple graphs?

@JimmyHoffa missing a legend

Jimmy Hoffa

yellow = question count per day
green = acceptable question count per day
red = unacceptable question count per day

Ixrec

that is interesting

Jimmy Hoffa

@Ixrec screw you too! You want to chart this shit in R? You go ahead and figure out how to put a legend on without getting a crazy damned bunch of lines drawing all over hell and back

Ixrec

what's the year/month when the green and red start touching again?

lol

Jimmy Hoffa

20:58

R is neat; but it takes some fiddling...

I really need to figure out how to create functions

just stringing shit together with temporary variables is really annoying

Ixrec

I'm sure it's buried in the documentation somewhere

Christmas miracle - I have reserved seats for a showing of SW tomorrow. :-D

Jimmy Hoffa

@GlenH7 I had a chance at that last week but passed

everyone in my office was offered them by some vendor for an pre-screening or day-of or something

user41796

This appears to be an additional showing they've added to help deal with the demand

user41796

I got nearly perfect seats and half the theater was still available to pick from

@JimmyHoffa tough call. I probably would have taken them. But I'm glad I get to see it with my kids first
