rolfl

12:53 AM

@SimonAndréForsberg No, the downvote is still useful. There's a bunch of crap that the answer is saying, the VM will never null out the previously set valu, but, in some threads, the value may never have been set to not null.

That's assuming a multithreaded application.

In a single-theaded application, the value will be null until you add an instance, after which it will always be not-null.

Also, in a multithreaded app, the value that is set could get overwritten by another thread which may not have known it was previously set.

So, the code is not thread safe.

Not at all.

Which is OK, so long as there is only one thread.

But, even single thread, and even "under heavy stress or memory use", the value will never be set to null after it has been set not-null first

Downvote that answer. Guilt free.

The accepted answer is not great either. It is mostly accurate, but completely ignores any multithreaded consequences.... the OP should at least be warned that in MT, the code is BS.

Phrancis

@rolfl sounds like someone should say something... I'll be happy to upvote a better answer from someone who knows better, like you.

On a 3 year old question?

Meh, 2 year old.

There, comment added:

I realize this answer is somewhat long in the tooth, but, it really should be pointed out that this answer is only true in a single-threaded use of the static values and methods. In a multi-threaded use case (which is likely the case here - it is android), the use of this system is likely to cause numerous unexpected 'features'. — rolfl 29 secs ago

I'm not sure what to do with a question like this: codereview.stackexchange.com/questions/4605/… I'm trying to come up with a good comment, but first of all, it's nearly 3 years old and who knows if the asker will even come look at the comment.

Jamal

@nhgrif He hasn't been around too recently. If important clarification is needed, then alongside a comment, it may have to be closed as "unclear what you're asking."

nhgrif

It's not really unclear what he's asking. He wants the code to run faster.

Jamal

Ah, okay

nhgrif

But it's unclear why he thinks it's necessary to run faster or why he thinks it's possible.

If I knew a way to speed it up, I'd just post that.

nhgrif

Yes.

Phrancis

Guessing, new user...

nhgrif

So, it's really interesting... in Objective-C (and this will likely carry over to Swift), we almost never throw exceptions.

I've never written anything that throws an exception.

I've also never written a try-catch block in any serious Objective-C code.

Phrancis

Is Objective-C == C# ?

nhgrif

No.

C# makes extensive use of exceptions and try catch blocks...

C# is under Microsoft and .NET and such.

Objective-C is Apple's language.

Phrancis

2:48 AM

Do you find Objective-C better in general?

nhgrif

I like Objective-C. Everyone else hates it. I've not done much with C#

Basically nothing.

I've done some Java, C++, and VB.NET

And a tiny bit of PHP.

People have a hard time getting over the syntax of Objective-C.

Phrancis

> Is there any way to find frame rate of an video? to precisly get all frames.

^^ nice grammar

nhgrif

The general rule of thumb for Objective-C exceptions is that the only things that throw exceptions are things that are logic errors.

Things that 100% can be completely avoided.

Phrancis

I would think, all things Apple considered, that it would be simpler than any Micro$oft version...

nhgrif

And as such, you shouldn't be using try-catches in high level Objective-C code.

Instead, things that the programmer can't control that could go wrong, such as File IO, this is handled with an NSError object.

The file IO methods all take an NSError ** argument. A pointer to a pointer to an NSError object.

Phrancis

2:57 AM

I'm a bit lost on what a try-catch is (I'm a db guy) but I feel that makes sense

nhgrif

If there was a problem during IO, the NSError object is set.

try-catch is error handling

So, if something throws an exception (to let the program know something went wrong), it the exception isn't caught (try-catch blocks catch exceptions) then the program will crash.

Phrancis

That doesn't sound good...

Dagg Nabbit

@nhgrif that's interesting... I've wondered if a language with no exceptions at all could somehow work

nhgrif

Most languages, such as VB.NET, C#, Java, they all use exceptions for things that can go wrong outside the programmers control, such as a problem reading a file, for example. This means in these languages, you write all of your file IO in a try-catch block.

Objective-C still has exceptions, but they are (or should be) reserved for truly exceptional behavior, and really, as I said, it's all behavior that the programmer can prevent.

Like index-out-of-bounds throws an exception.

Dagg Nabbit

yeah, but do you really need them, I wonder, or could you just break control flow without "throwing" anything

nhgrif

3:01 AM

But you're not using try-catches for index-out-of-bounds exceptions in Java

So, in Objective-C, if you're going to read/write from a file

let's say you're going to read from a file

If the read is fine, the method returns an NSString * object (assume we're using the method that reads it as plaintext)

If an error is encountered, internally in this method, there likely is a try-catch block. But to the end user of this method, the result is that the method returns nil instead of an object.

And the pointer to a pointer to an NSError object is set to a new NSError object that contains details about what went wrong.

Dagg Nabbit

a lot of Lua code works like that

it's best bractice for the first return value to be nil if something went wrong

and you can return multiple values so the next return value could be an error message or something

nhgrif

So, instead of try { file IO code } catch { blah }, it's more like: file IO code; if(!error) { all is fine; } else { handle the error in some way }

Dagg Nabbit

where does the **NSError live though

Phrancis

Dagg Nabbit

nhgrif

Dagg Nabbit

3:07 AM

no wonder people don't like that syntax

so the error is a passthrough variable basically

that's not bad

nhgrif

[NSString stringWithContentsOfFile:datePath encoding:NSUTF8StringEncoding error:&error]; == NSString.stringWithContentsOfFile(datePath,NSUTF8StringEncoding,&error);

Dagg Nabbit

good lord

Swift's syntax is more like Java/C# etc

Although the variables are still named.

rolfl

@Jamal - new SEDE query ....

data.stackexchange.com/codereview/query/206619/…

Dagg Nabbit

3:09 AM

that looks much more natural to me

i wonder why ObjC deviates so much from C-style

nhgrif

There are other languages that use the square bracket syntax.

the thing is, to me, it actually looks a lot, lot more clean.

It definitely does.

rolfl

3:16 AM

Yeah, I have now ranked it by feedback ratio as well.

There are really two questions answered by that query.....

1. how much people vote....

2. how much value is generated by a person's contributions to CR.

Dagg Nabbit

I don't think you can measure the value of contributions by the number of upvotes

Phrancis

@nhgrif DELETE FROM foo WHERE SomeId = (SELECT TOP 1 * FROM #SomeTempTable);

nhgrif

Currently, the Objective-C tag is mostly me answering questions by this user: codereview.stackexchange.com/users/14608/bazola

rolfl

@DaggNabbit The value added is complicated....

but, it basically amounts to the votes the person casts, together with the votes on answers related to questions the person asks.

nhgrif

@Phrancis I don't want to delete from foo. I want to delete the top row in the temp table and the temp table doesn't have an ID column.

Phrancis

3:19 AM

Oh. Well that works OK then.

rolfl

i.e. if I ask a question, and it generates 5 answers, and the average answer score is 2, then I have added a value of 10 to the site.

Dagg Nabbit

I think people vote more on things they can understand easily

nhgrif

I don't agree with that @DaggNabbit

Dagg Nabbit

and vote less on things that are harder to digest

rolfl

I would agree with that .... but, the second thing is the feedback ratio... which is interesting.

Dagg Nabbit

3:20 AM

@nhgrif I'm almost positive that it's the case

nhgrif

People are willingly to vote somewhat blindly on things they don't understand.

Or haven't even looked at to determine whether or not they'd understand it.

Phrancis

^^ guilty.

rolfl

If you assume that people 'should' do the following: vote on any question they answer, accept an answer to their own question, vote on answers to their own question......

the vote can be up, or down.....

nhgrif

That's a fair assumption @rolfl

rolfl

but, if you have a feedback ratio of 1, then you have voted/accepted on each of those opportunities (or on some other thing as a substitute).

So, people with a feedback rato of 1 are breaking even... less than 1, are not, more than 1, are giving feedback on more than just what they participate in.

Dagg Nabbit

3:22 AM

I have very rarely gotten an answer that I felt was thorough enough to be the "one correct answer"

nhgrif

nhgrif

Weird. If I sort by name, I don't see me.

oh

Dagg Nabbit

@Phrancis I may have to start interpreting it like that, but I'm always hoping another answer might come along

nhgrif

You can always change the accepted answer.

I was really hoping the guy who posted this question would come back for more: codereview.stackexchange.com/questions/51670/…

Dagg Nabbit

yes, but accepting answers lowers the chance of it being answered again

Phrancis

Here's a thumb rule, if @rolfl posted it, it's likely the most helpful answer.

Dagg Nabbit

I'm mostly here to get good reviews, not to score rep, help other people score rep, help the site get out of beta, etc.

nhgrif

3:26 AM

Welp, if you post an Objective-C question, already having an accepted answer isn't necessarily going to shy me away from posting an answer.

Dagg Nabbit

and checking answers seems detrimental to that

nhgrif

In fact, this week I stole an accepted answer here and on SO.

rolfl

@Phrancis not always true ... been batting a bad average recently.

Dagg Nabbit

I think you're in the minority there.. if I see the asker has accepted an answer I don't waste my time unless the answer was pretty bad

that has definitely been the trend on SO... once something gets checked, answers and views fall way off

Phrancis

@rolfl for all it's worth, every answer you've posted on my questions has been helpful.

rolfl

3:28 AM

@DaggNabbit That's refreshingly honest, but it is symptmatic of a trend on SO that we are trying to avoid on CR.

Dagg Nabbit

I know, I'm just not sure it's the SO content that causes it rather than the SE format

Phrancis

SO: $this->sucks

nhgrif

I do wish questions like these had a way of eventually marking an answer as accepted: stackoverflow.com/questions/21234335/nstimer-does-not-stop There's been no activity for almost 6 months. The user's last activity is almost just as long ago. There's a posted answer (mine) with 10 upvotes, and several other answers (but none with more than 1 upvote). I don't even care about the 15 rep... but seeing the question is "unanswered" is a little irriating.

rolfl

@DaggNabbit The numbers make no sense though, your ratio is 2.94

which means you have voted almost 3 times as often as what would be 'anticipated' for your questions/answers.

Phrancis

@nhgrif seems like people on SO just don't give a flying expletive

nhgrif

3:31 AM

CodeReview, however, should almost get rid of the accepted answer altogether though. On StackOverflow, you are posting a problem and the answer with the checkmark is the one that resolved the problem.

rolfl

Accept on code review is complicated, but the alternative is ... worse.

nhgrif

On CR, you're posted code you'd like someone to look over. Good answers here will not only provide some improvements that can be made, but hopefully also not overlap any other answers.

Phrancis

For myself I generally "accept" the answer that has the best advice about best practices/design/performance

nhgrif

Take this question for example: codereview.stackexchange.com/questions/55735/… I got the checkmark for the accepted answer. But honestly, I would've thought my other answer to this question should've deserved the check mark. It's less specific but addresses a much bigger, much more important issue.

Phrancis

Though most of the time other answers provide good tips as well, usually one stands out where someone has really taken the time to look at your code as a whole

nhgrif

3:34 AM

And if you compare my more specific answer (the accepted one) to GraniteRobert's answer, his is probably better and deserves the check mark over my accepted one.

But I probably got the check mark because the asker like my combination of answers

rolfl

I feel a lot of the time I get 'high rep' votes.... people vote for my answer because it's my answer.... speaking of which, I think I may be in line for a serial-upvote reversal today.

nhgrif

Also... I just realized that the question is tagged oop. Is that really a necessary tag?

Dagg Nabbit

@rolfl I didn't understand that either, I don't vote that much

Sometimes it's purely about length. Sometimes the separate answers come at different times. Sometimes the answers review entirely different topics.

Dagg Nabbit

@nhgrif, @rolfl are you guys doing that mostly because a single answer would be really long?

nhgrif

Sometimes. But not always.

that's a big part of it too.

nhgrif

I have two not-so-short answers, and the question is still longer than my answers combined.

This question really should've been broken up into multiple questions.

Dagg Nabbit

see that's a case where it looks to me like the shorter answer could have just been tacked on to the other one

nhgrif

If anything, I feel I'd move the last section of the longer answer down to the short answer.

Dagg Nabbit

maybe that's why multiple answers feels weird to me... harder to reorganize. Don't want to move stuff from one answer to the other, because it sort of invalidates votes

nhgrif

Where in the short answer and in the last section of the long answer I'm addressing some specific implementation details

rolfl

3:57 AM

One of the key parts to Code Review is that you can answer any part of the question you want: "Do I want feedback about any or all facets of the code?"

A complete answer would often be unfeasible for a single answer, and requires multiple people o do anyway.

Dagg Nabbit

that is true... i think multiple answers over a few days makes a lot of sense

Anyway, this has been discussed on meta a number of times: meta.codereview.stackexchange.com/…

Dagg Nabbit

4:02 AM

hahah, one of those was mine

nhgrif

The thing is, you don't need to see the entire project to review a piece of it. And if context is necessary, it could be provided via a github, but you post a handful of questions for several distinct/important classes in your project.

Then you can also post a question that focuses more on having the big picture reviewed.

But for the big picture review, we don't need to see every single line of the entire project. We don't need to see the implementation details of all the classes. We need to see how the classes interact with each other.

But a question that posts a entire project with 10 or more classes and says "Hey, review me!" is kind of unacceptable. That's essentially 11 questions, at least, all packed into one.

It's pretty entertaining.

If you look at any given recently posted Objective-C/iOS question, you can tell whether myself or rmaddy is around because the post is most likely last edited by one of us to remove the xcode

Q: Merge Sort: Null pointer exception when using compareTo() method

This is in connection to the Algorithms 1 class going on at coursera. The instructors uses Comparable interface so that the implementation doesn't depend on type. Here is my implementation: public class MergeSort { private static Comparable[] aux; private static void sort(Comparabl...

Q: A functional binary heap implementation

I've implemented a binary heap in F#. It's pure and uses zippers for tree modification. To test it out I have implemented heap sort using it but it takes 10 seconds to sort a list of 100 000. Regular List.sort is instant and since heap sort should have the same complexity I'm wondering what I can...

Q: Processing large file in Python

I have some code that calculates the "sentiment" of a Tweet. The task starts with an AFINN file, that is a tab-separated list of around 2500 key-value pairs. I read this into a dict using the following function: csv.register_dialect('tsv', delimiter='\t') def processSentiments(file): with ...

@Phrancis good luck with your move, hope it goes smoothly!

Looking for a good PHP / MySQLi project suggestion

Or multiple projects

"Don't use PHP and MySQLi" is not a suggestion btw ;)

Vogel612

@CodeX well that would have been mine..

CodeX

@Vogel612 haha i know its not the best platform but i love it

sure, do what you are best with ;))

@DaggNabbit What is a "real code review" anyway?

CodeX

9:55 AM

@SimonAndréForsberg 1. "REAL - actually existing as a thing or occurring in fact; not imagined or supposed."
2. "not imitation or artificial; genuine"

Im guessing a REAL code review is pretty rare

Simon André Forsberg

@CodeX I was more thinking of the Code Review part. I know what real is. But what is a real Code Review? Is it just because it's on the internet that it's not real or what is it?

CodeX

@SimonAndréForsberg They are just asking for a genuine review of the code as opposed to a "spammy give me more repz" version

A code review could in fact be "Nice code, looks really good"

Simon André Forsberg

@CodeX That part I think is used way too little around here. Sometimes we just focus on the bad parts.

CodeX

@SimonAndréForsberg Indeed but it is the bad parts that make the code bad, so i guess after suggesting fixes the code becomes "Nice Code", i wonder how many people take their review the wrong way and cry themselves to sleep..

I think the biggest problem as a beginner is knowing who is right, just because the code suggested works doesn't mean its the best answer, yet you will see it marked as such

I was told to use || instead of && yet i needed to use &&, was it a misinterpretation of my question? maybe.. maybe not..

The thing about the internet is that, everyone has an opinion even if they don't know what the F$%K they are talking about

Oops bit of a rant there.. sorry about that

@SimonAndréForsberg you know code reviews are an actual thing in software dev right

Code review

Code review is systematic examination (often known as peer review) of computer source code. It is intended to find and fix mistakes overlooked in the initial development phase, improving both the overall quality of software and the developers' skills. Reviews are done in various forms such as pair programming, informal walkthroughs, and formal inspections. Introduction Code reviews can often find and remove common vulnerabilities such as format string exploits, race conditions, memory leaks and buffer overflows, thereby improving software security. Online software repositories based on S...

Simon André Forsberg

@DaggNabbit Yes, I've heard about it, but I don't get what differences those from what we do here?

Dagg Nabbit

if you ever participate in a real code review you'll understand ;)

some of what we do here comes close but some does not

CodeX

So, code reviews should be carried out by competent programmers only?

Does anyone here do any paid work in reviewing for companies / individuals?

Dagg Nabbit

i have, yes

and yeah i think reviewers should be competent

the thing i was referring to earlier though was a tiny snippet of code that i didn't think really warranted a review, since it was not useful by itself and completely lacked context

@DaggNabbit Do you have a degree or any form of valid paper work to say your competent?

2. Another term for a panic attack induced by social anxiety and/or physical surroundings.

CodeX

@DaggNabbit Im just thinking from a clients point of view, they would need to know you were capable before taking you on unless they allowed a trial run or knew you as a person.

@Matthew Monking here means something different

Dagg Nabbit

yeah but the client doesn't care about a code review, it's more of an internal thing

Matthew

@CodeX Oh

Dagg Nabbit

@CodeX unless you mean a company outsourcing code reviews, that i don't have any experience with, just internal ones

CodeX

10:45 AM

@DaggNabbit I see, i struggle to get any real work in coding / IT in general because i don't have a piece of paper to say i spent 3 years at uni and at 31yrs old i don't think id fit in well on a campus

@DaggNabbit Yeah i guess i should have said freelance

skiwi

@CodeX A bet would be to maintain some kind of open source project, which preferably actually gets used... I think that is one of the things you can do yourself

Dagg Nabbit

^ that's not a bad idea at all

skiwi

Then I'd say you have higher chances... Some companies might totally ignore that, but do you really want to work for such companies?

CodeX

@skiwi Yeah, i have a project that i want to make open source, just not ready for all the kicks and punches yet

Id like to freelance a bit and get some experience

skiwi

I'm not so sure about freelancing, working in a company does give more experience I think

Dagg Nabbit

10:49 AM

if you have spare time, you could do some free work for a non-profit to beef up your portfolio

skiwi

But that depends mainly about the fact that in companies you need to integrate your program with all kinds of running systems

Dagg Nabbit

like an animal shelter or "save the children" thing or whatever

skiwi

And as freelancer that is still possible, I just think less likely

CodeX

Great suggestions here, i have done some "free" work just for the experience, i will definitely get an Open Source project going and see what sort of feedback i get

@Matthew meta.codereview.stackexchange.com/a/1678/46720

I enjoy building websites but would rather be building applications, maybe plugins, not sure what platform i would do that on though

Matthew

Lol

@skiwi: the main advantage of working in a company as opposed to freelancing is that you can learn from other/better/more seasoned developers
