This week we chat with our CEO, Prashanth Chandrasekar, about the milestones our community achieved in 2019 and what we have planned for 2020.

Three months ago, we interviewed Prashanth during his first week on the job. Now, with a full quarter of work under his belt, our new CEO reflects on what we accomplished over the last decade and lays out his vision for where Stack Overflow, as a company and community, will be heading over the next year and beyond.

Paul explains why engineers prefer to give blunt feedback, even in a public setting, and why that approach makes sense for someone working on mission critical software systems. …

A: Code Review is getting boring

Jianmin ChenI understand the argument about codereview questions are boring, poor quality, too forgiving. I asked more than 35 questions from Nov. 2016 to August 2018.

I think half of it is unrelated noise, but part of it could be considered an answer.
It's definitely not worth any upvotes at the moment, but it might be if the noise is cut. But that would be a bit drastic.

This is an interesting problem. If the code is working as expected and all you want to do is improve performance, you might get faster and better responses by posting your issue on SE Code Review. Just a suggestion. As far as I understand the problem, this might be a candidate for parallelization: Have you considered using the multiprocessing package, dividing your list of rows into sublists of rows and threading the work on them?

@Peilonrayz I wonder if we should be migrating that question to meta.CR.
Probably not worth it, but still.
Feels a bit odd, closing the question knowing that OP can't ask the question on the relevant meta because of lack of reputation.
 
We can try, but ultimately if I were the OP I'd be like why do I want -8 on Meta, to be migrated and then told "post a question". Not really the best PR.

@CaptainObvious I like how that text cuts-out.
 
@CaptainObvious @Mast Python doesn't use 4 dot version specifiers. I assume you mean just 3.7.6 or 3.7.6b1 - if it's a beta. You can check with sys.version or sys.version_info.
 
@Peilonrayz Heh, good catch. That's actually the version of WinPython, not of Python itself.
Drop the 0 and you got the actual Python version, 3.7.6.
 
Sweet, you're using a newer version than myself so I should be able to answer fine, :)
 
Fixed.
@Peilonrayz I'm using a newer version than you? Never thought that would happen.
 
11:16 AM
I have Python 2.7 and 3.3 - 3.7 all installed. So I can test version incompatibilities. And keeping them installed properly - which I some how haven't - never mined up-to-date is a pain in the ass. I hate updates >:(
 
Ain't that the truth.
At home I usually whip-up a VM if I need a specific version without messing-up my 'normal' installation.
 
Unfortunately that doesn't seem like an option with test runners like tox or nox.

@Mast I can't be sure of that until I see the question.
@Mast ... or so we think...
 
@HimBromBeere I would guess the OPs intent is to have a good solution in their environment, which they described in the body and in the tags as ASP.NET Core. And a good solution is not to reinvent the wheel, no matter how great that new wheel may follow certain principles. The best solution is to use the existing wheel that is already following certain patterns. The accepted solution through the lens of ASP.NET Core to me looks like there is something hidden. There must be some reason why the existing system was not used. In a code review I would certainly question that choice. — nvoigt 57 secs ago
codereview.stackexchange.com works for small code changes. I suggest reading Martin Fowler’s refactor and uncle bob’s clean code. Learn SOLID pattern. Then RGB TDD. Then DRY/kiss. The idea is to learn code craftsman skills. Then learn how to get things done. TDD valuable for prototyping and testing. But not day-to-day unless people’s safety or lives may be effected by your code. Book on Domain driven design is the next step. What your program hopes to solve should be a big influence to how you code it. — TamusJRoyce 15 secs ago

@Peilonrayz The DEFAULT = 0 in the BaseClassifier, this doesn't have to be self.DEFAULT = 0? It's automagically selfed?
 
@Mast welp ... that's some semi-thinly veiled attempt at self promotion there
 
@Mast Oh no, it's a class variable. Which means it's defined on type(self) not self. So yeah it doesn't require self.
 
And does anyone know why rev 4 wasn't caught as invalidation here?
It's autoflagged for re-opening now, with 2 answers already on it. Bit of a mess @Vogel
 
@Mast possibly because the question was closed at the time?
 
@Vogel612 I'm fine with re-opening that question, but that would mean nuking 2 answers that shouldn't be there in the first place.
 
2:05 PM
Interestingly, at least to me, classes are just another scope so you can do things like:
>>> class Foo:
    	def bar(self):
    		pass
    	print('hello', bar)


hello <function Foo.bar at 0x000002226C669158>
 
@Peilonrayz Right, it exists over all instances.
The amount of times I use that is just about never, I think.
@Peilonrayz Interesting.
@Vogel612 Absolutely.
And promoting all the wrong things.
 
@Mast Pretty much yeah.
 
@Mast afaict none of the answers have actually been invalidated by the edit
and if you say it should be reopened after the edit, I'm very much okay with that
I assume you did verify that the code does now pass the test cases on hackerearth?
 
@Vogel612 Perhaps first paragraph by Ray.

I'm not sure it's working
These are different to TLE which they are also getting.
 
2:15 PM
@Vogel612 It works for the example input/output, don't have the means to verify it against other values.
 
yea, I tried to check against the site, but the signup there was being annoying so I didn't
 
Wait, perhaps I can do this...
 
I've confirmed it's still broken, according to the site.
 
Eh, nvm.
If it were up to me, we'd completely outlaw TLE and the likes. But, you know...
I mean, if you can't complete the bloody challenge, what are you doing here?
 
It's not a TLE problem. It's just a flat out wrong answer.
They have 2 wrong answers and 7 TLEs - which probably are wrong too
 
2:18 PM

Why did we even try to salvage this again?
And how did it get +4/-3?

I had no idea that there is Code Review as well !! — IrateINWIT just now
 
@Mast First year students.
 
@pacmaninbw When I started programming, we didn't have internet. We had a second-hand book.
If there was a bug, you went looking for it. There was no such thing as untested code.
Good thing too, since I didn't have a debugger either.
 
@Mast True dat. I got my BS in computer science in 1985, no internet.
@Mast depending on test coverage there may have been untested code.
 
Every code was used. If it produced the correct result, it was tested, right?
Not necessarily well tested...
 
It was hard to tell if every path through the code was tested.
 
3:13 PM
Hence looking for the bugs.
 
Hence code reviews.
I had a teacher that ran the code and found lots of student bugs, I got an A in his class.
He taught me Unix, Operating systems and C.
My Operating systems code had one of the fewest bug counts.
@Mast You're right, all code presented on CR should be tested before it gets here.
 
@Mast I remember the first time I learnt about so many code review 'comments' first hand. Normally the price for the knowledge was a dead a project. :/
 
@Peilonrayz Heh, I remember setting a self-built motorcontroller on fire due to a minor bug I thought would never happen.
It did happen and the darn thing shorted out.
 
@Mast I have a very nice jacket from a company I worked for from 1984 to 1999. The back has a cartoon of people walking through a swamp with shot guns hunting giant bugs. The caption is the Great Bug Hunt of 99.
@Mast I saw 4 voltage supply boards go up in smoke for 85 to 99. Not my code.

Not sure I understand. When you create a shelfset, you can select which files they contain. Do you mean that you are having to make changes to the same source files for work item A and work item B?

Prashanth Chandrasekar on January 21, 2020

As we enter a new decade, there are tremendous forces converging—cloud computing, big data, AI, ML, and an increasingly diverse group of young coders from around the world. Every day, millions of developers visit Stack Overflow to find information they need as they push these exciting new technologies forward. There has been a massive shift since my days as a computer engineering graduate. I was fascinated by the power of languages like Perl, but had only my teachers, classmates, and a few small web forums and mailing lists as a community to support my learning. The numbers below really put into perspective the impact that our community generates and the opportunities that lie ahead: …

 
If you're going to call getStructs many times, it makes sense to construct a map of inputs so that you can find things in O(1) rather than O(n). And I'm not sure how you plan to use those other arguments, but you should probably pass references to pointers, rather than references to objects. But this now looks like a question better suited to Code Review. — Beta 42 secs ago

"Merge" was probably a poor word choice there. From my understanding, it's not a dump of all these scopes into Stack Overflow.
