@Malachi I don't get it.

@SimonAndréForsberg - it's somewhat obscure:

Or rather, it is an 'in the know' joke - if you are not in the know, you have no idea, and it's just frustrating.

Oooooooh.

Forgot about that XKCD.

I have so much code I want to have reviewed! Where should I even begin?

@SimonAndréForsberg from the beginning

2:40 PM

@kleinfreund I'll look over it.

Don't hurry. ;)

Also there is an example post on how to create new posts in the _drafts folder.

@syb0rg no hurry, it's already merged

Heya :)

C# threading question, anyone? What's wrong with this lock object?

public object Lock
{
  get
  {
    return this._lock;
  }
  private set
  {
    this._lock = value;
  }
}

2:42 PM

@amon You looked over it?

@kleinfreund Where did the license go?

@syb0rg yes, or else I'd be hypocritical. The license was for the fonts, now removed

This was the font license for the Roboto font.

@amon I thought you did. I was just looking over all of the changes right now.

(sorry to crash in like this - hi guys!)

notice there currently is no _posts folder. Needs to be created for the first post to be made.

Heya @lol :p

Simon André Forsberg

2:44 PM

@lol.upvote Is there anything wrong with it?

public ItemXmlNavigator XmlDescriptive
{
  get
  {
    lock (this.Lock)
    {
      if (this._xmlDescriptive == null)
        this.XmlDescriptive = this.IsPrefItemModified ? this.DocumentItem.PrefItem.GetDescriptiveXml(this.XmlDescriptiveOptions) : this.DocumentItem.PrefItemDescriptiveXml;
      return this._xmlDescriptive;
    }
  }
  private set
  {
    this._xmlDescriptive = value;
  }
}

They're locking on a public property.

@lol.upvote Locks should be privately-owned by the class which uses them.

And I was wondering why my code was deadlocking.

(this is 3rd-party decompiled code BTW)

Simon André Forsberg

@lol.upvote Yeah I was about to say that. It felt wrong to use a lock as a public object...

Do we get 20 stars a day per chatroom?

2:46 PM

how can I avoid my code (consumer of this piece of crap) to deadlock, given that this code is "frozen"?)

Simon André Forsberg

@lol.upvote I thought the code snippet you post didn't work at first.

@lol.upvote Is your code the only consumer?

No

Simon André Forsberg

@syb0rg Yes. 20 stars per user per day per chatroom

Hence the occasional/random deadlock

2:47 PM

@SimonAndréForsberg Cool, thanks.

I'm F'd, right?

Simon André Forsberg

@lol.upvote At least the code is.

Is your code helping the cause the deadlock, by acquiring more than one lock?

Simon André Forsberg

So considering we got 8 users here at the moment, we have 160 stars to play with today! (Sounds like a dream, huh @Malachi?)

5

I'm just calling the method-disguised-as-a-getter above, and it's freezing. I figured I'd decompile the library to see why

2:51 PM

Or have other consumers already deadlocked, and you're just trying to acquire one (already deadlocked) lock? In the former case, avoid causing a deadlock by not holding another lock before/when you try to get this one.

problem is, I wasn't expecting a simple property getter to be doing this.

@SimonAndréForsberg 10 people should star everything that I say until I get that stupid badge.. or wait.....

I didn't even know I was acquiring a lock by calling that getter

Being able to set (i.e. change) the lock object property from outside is a 'WTF?'.

I already have the outspoken badge.....LOL :)

2:52 PM

Well, congrats. I don't.

2

:D

But with activity comes starring. :p

@kleinfreund that's only a matter of time ;)

Exactly.

@ChrisW it's the scary part, indeed!

I have outspoken, but not on this site (yet).

3

(wait, have I just posted proprietary, illegally decompiled code on a public chat?)

4

2:54 PM

@lol.upvote does chat fall under the stack licensing thing?

So you do hold another lock before you try to acquire this one? Debugger might show whether that other lock of yours is part of the deadlock, and which other thread is deadlocking on it.

@lol.upvote want me to flag it for moderator attention? you will probably get a hidden badge

@lol.upvote "Waiter, there's a fly in my soup!" -- "Ssh! Don't tell everyone: everyone will want one!"

2

@ChrisW I don't control the other threads.. I need to be able to call that getter no matter what.. I was thinking of spawning a Task that could time out, could that work?

@Malachi don't! ;)

..or it would eventually abort, leaving other threads deadlocked and the app frozen forever... i.e. no change from current situation...

I just starred something because it referenced Star Trek. dang it I am a nerd/geek

2:58 PM

But why, Star Trek is great.

Also got my little brother into watching it.

@kleinfreund I watched everything they had on netflix streaming last year... I am working on Battlestar galactica right now

@ChrisW this would be a thread-safe implementation of the getter right?

public ItemXmlNavigator XmlDescriptive
{
  get
  {
    object obj = new object();
    lock (obj)
    {
      if (this._xmlDescriptive == null)
        this.XmlDescriptive = this.IsPrefItemModified ? this.DocumentItem.PrefItem.GetDescriptiveXml(this.XmlDescriptiveOptions) : this.DocumentItem.PrefItemDescriptiveXml;
      return this._xmlDescriptive;
    }
  }
  private set
  {
    this._xmlDescriptive = value;
  }
}

Watched DS9 in December for the second time.

@lol.upvote The good thing about a new Task might that you could write such that it doesn't hold a lock while it tries to acquire the new lock? But if the Task blocks forever and you wait on the task, someone might still deadlock on a lock you hold. I don't know whether (and I'm not at all sure how) a Task can timeout if it's blocked on acquiring a lock.

Aaaan out of ammo.

3:01 PM

I expect that object obj = new object(); be a static object, or at least persistent, e.g. a private instance field of the class.

Naive code often lock(this) which has the same problem as locking a public property i.e. this is too public and can be locked from outside.

@kleinfreund I have watched several episodes when I was younger and it was on tv. but that was the first time I watched all the series.

and netflix was missing one of the first set of movies, I was disappointed. I have to have the dvd sent to me they won't stream it...

private object obj = new object();
public ItemXmlNavigator XmlDescriptive
{
get
{
lock (obj)
{
if (this._xmlDescriptive == null)
this.XmlDescriptive = this.IsPrefItemModified ? this.DocumentItem.PrefItem.GetDescriptiveXml(this.XmlDescriptiveOptions) : this.DocumentItem.PrefItemDescriptiveXml;
return this._xmlDescriptive;
}
}
private set
{
lock (obj)
this._xmlDescriptive = value;
}
}

Wow. :( I wish we had Netflix here.

@ChrisW thanks a million!!

Ah. I love the smell of handled flags and upvotes in the morning. :-)

2

3:08 PM

;)

@ChrisW wait, the Lock setter is private, doesn't that come down to the same as a private field?

Going to make myself a cup of tea. Later.

Oh, and I have four votes left...

@lol.upvote Yes it does. So less wtf.

Even so, why would it ever be changed? I'd usually expect it assigned/defined once, in the constructor. If they change internal state, do they shrug off their old lock and start locking on a new object?

@ChrisW no clue, these people write C# with a VB6 mindset. That explains the "WTF" threaded code.

3:18 PM

I'd just assign to this._lock in the constructor; maybe their constructor assigns to this.lock instead. Or maybe they coded it as a "public object Lock { get; private set; }" and your disassembler sees a compiler-generated field named _lock (I don't know because I'm not familiar with MSIL).

Simon André Forsberg

@Jamal I'm glad you do. Except that... it isn't morning. :)

@ChrisW looking for the constructor... came across a scary "public bool IsLocked" property, with public getter AND setter.

dammit

Well, fair enough, I did go to bed after it officially became morning here.

@ChrisW found the constructor. The lock is assigned in the constructor. yay!

Any API documentation / usage examples to go with those public methods? Or would that have been too much to ask? IsLocked isn't bulletproof:
if (!foo.IsLocked)
{
... there's a race condition here ..
lock(foo.Lock);
... access foo without deadlocking ...
}
else
... too dangerous to try locking right now ...

... but using IsLocked like that might be better than nothing if you are deadlocking. They should have implemented a thread-safe TryLock method if they expected you to do/need that.

How about you try Monitor.TryEnter(foo.Lock) since they do expose their Lock as a property?

A: Given N*N matrix, rotate it by 90 degree to left and right without extra memory

You ask many questions on CodeReview, which in itself is good, but you have to start helping the reviewers actually review your code. You have this habit of dumping code and expecting a review. It does not work that way (very well). For a start, let's review the ideal process for a 'real' review:...

@ChrisW in my dreams, yeah

I may be stirring some trouble..... but the asker needs to start thinking before he posts ... ;-)

@Donald.McLean Let me star that for you....

^ I'm suspicious of this answer: because it addresses the question in the text of the OP, but doesn't reference the specific source code presented with the question.

@ChrisW ugh. the Lock property isn't exposed by the interface.. and the implementation is in an internal class - I'm F'd.

How is it deadlocking, then?

Do you own a lock before you call that property? And is that previously-held lock of yours part of the deadlock?

4:20 PM

Nope. There's possibly 12 DLL's accessing that code, I'm contacting their support.

random question
The avatar images beside the room name, are all those people active in chat?
I am guess from the fade on some of them that it indicates people that WERE here?

If so anyone else have trouble telling which are actually faded backgrounds and which are just light avatars?.......

I don't have trouble.. Most of them are fade out.

I think faded avatars are people still technically in the room, but that haven't participated in a while.

They fade out with inactivity, but they are still in the room.

Ha! That's technically a Manji!

Was expecting some historical references or something

Yes, it is.

The swastika (卐) () is a symbol that generally takes the form of an equilateral cross, with its four arms bent at 90 degrees. There are many similarly-shaped symbols that westerners refer to as swastikas (see examples below), but the indigenous users of these symbols never called them by this name. The earliest archaeological evidence of swastika-shaped ornaments dates back to the Indus Valley Civilization as well as the Mediterranean Classical Antiquity and paleolithic Europe. Swastikas have also been used in various other ancient civilizations around the world including Turkic, India,...

There is even a unicode symbol.

@SimonAndréForsberg Yeah, kinda.

ultimate TTT? WTF is ultimate?

I'm in

@syb0rg we keep the weekend-challenge tag?

Simon André Forsberg

@lol.upvote I believe the pictures explain that :)

8:28 PM

@syb0rg you rang?

oh that's AWESOME!! Sudoku meets Tic-Tac-Toe!!

@lol.upvote Yes, but just change the definition a bit. It is meant to be done on the weekends in free time, but people are busy and need more time for projects.

Simon André Forsberg

@lol.upvote Yeah, kinda :) The concept really takes Tic-Tac-Toe to a whole new level

I'm lovin' it

@apieceoffruit Yeah, I was just saying I haven't seen you on here in a while.

Simon André Forsberg

8:30 PM

@syb0rg I've already edited the tag to reflect the lack-of-weekendness, but some meta-posts might also need editing

Ok so how about weekend-challenge is on for all of February, we implement the ultimate tic-tac-toe?

@kleinfreund What do you mean?

The tag wiki will need an edit

@syb0rg Huh?

@kleinfreund You pinged me a while back about a list for the community site?

8:31 PM

@syb0rg Oh, yes. I just wanted to know if have plans for the site and so on.

@kleinfreund The GitHub site was created to host the code of CR community projects and the reviewed challenge code.

@SimonAndréForsberg would you write up the meta post? I feel like I'm monopolizing the featured meta posts...

@lol.upvote Hey, I'm reliable.

Simon André Forsberg

@lol.upvote And I was just about to suggest to you to make a meta post :)

8:33 PM

Most of the time

@syb0rg Should this code also be available at the site?

@kleinfreund The site will point to the GitHub organization that hosts the code.

Do you think otherwise?

@sim I really don't mind my next tag badge to be on the fun tag, it's just... you know.

Well, I don't know anything about your challenges, but it could be a possibility to have the code submissions be available at the site.

@syb0rg yeah I haven't had time to contribute much. I found this site a few days before I took my work days and only started getting back to the important stuff now!

8:36 PM

@apieceoffruit So you are going to be on more often now?

Q: CR Weekend Challenge

Those of you that weren't following what's going on in the chat room might have been taken by surprise by a recent avalanche of Rock Paper Scissors Lizard Spock posts. This is how it started: OK, weekend challenge.... we all solve the Rock Paper Scissors Lizzard Spock problem with our 'favou...

discussion fun weekend-challenge

@syb0rg should be, I haven't been doing as much recreational coding as I would like.

@apieceoffruit Yay! Have you voted recently?

yesterday, by syb0rg

We could really use your ammo.

hehe. this is definitely the best meme here

I reference it a lot. :)

8:39 PM

@syb0rg on what? Anything in particular or just general post answers?

Simon André Forsberg

@lol.upvote Should we let the meta users have their say in the challenge as well or should we just say: "Let's make TTT Ultimate!" :)

@apieceoffruit Particularly answers that don't have any upvotes and are good answers.

But yeah, anything goes for voting.

Just make sure to use all of them!

Simon André Forsberg

I like it that there's a notice on the meta Weekend Challenge post saying "Post is related to a rapidly changing event."

Gotta get into my alcove the regenerate my ability to vote.

@Jamal put it there, because each week there was new stuff. If it's going to be monthly, maybe it can be removed.

8:41 PM

@syb0rg how many do you get? I do tend to upvote 5-6 things a day

max 40

^^^ yep

Though somehow @rolfl was able to squeak out 43 votes.

But we are more. Two people can vote 80 times. Think about it.

Q: Cryptography: Implement AES on CTR mode using pycrypto

I'm trying to implement CTR mode by myself (only decryption by now), using only AES built-in functions from pycrypto. It means that I'm not supposed to use mode=AES.MODE_CTR. However, I know that using AES.MODE_CTR would be more simple, but I'm doing this as a learning experience. What I'm doing...

python cryptography

@SimonAndréForsberg I think the vote-for-next-challenge is what got the thing exhausted. Let's just say "implement Ultimate TTT by Feb.28 and post it here for review", we'll see what we get :)

8:42 PM

Two people with one being rolfl can vote a whopping 83 times!

Good night all. See you tomorrow. Happy coding!

^^ tomorrow he's voting 37 times max

It's called Monkey-Math You have 10 bananas, you give monkey 5, monkey has 10 bananas!

haha

'night @kleinfreund

Cya @kleinfreund

That doesn't even make sense.

Simon André Forsberg

8:44 PM

@lol.upvote That's possible actually, there were many suggestions in the beginning but after a couple of weeks there was only two suggestions, and the last week only one (which no one has implemented still AFAIK)

@rolfl Do you know how you got 43 votes?

that's zombie-looting

you vote on a post that gets deleted the same day, get your vote back; the vote count keeps going up on the voters page.

Simon André Forsberg

@syb0rg Vote, post gets removed, you can vote an additional time

that ^

Oh, that's silly.

8:46 PM

it's just a "bug" in the display, actual vote count is really capped at 40.

@syb0rg - you can use it to your advantage and rep-free. Down vote when you vote-to-close.

@rolfl Do you get your vote back when it gets closed?

Or is it only when the OP deletes the post?

Zombie looting: when you've downvoted (upvoted?) a question that ends up being deleted (on the same day), and then you get your vote back. The vote count doesn't deplete though, which means zombie looting allows you to appear to have voted like 43 times on a single day, and steal the show on the voters tab.

Simon André Forsberg

@lol.upvote So are you or I going to write that meta post?

@SimonAndréForsberg if it's not posted by the time I get home, have fed, bathed and put the kids to sleep and back online, then I'll post it.

You have, uh, about until shortly after votes get reloaded

Simon André Forsberg

8:54 PM

OK, we'll see then. I'm gonna grab something to eat, and then it's soon tomorrow :/

@Pops it just won't stop, eh?

Simon André Forsberg

I might post it, otherwise you will have the honor :)

cool

@lol.upvote: What was that?

@jam what was what?

8:57 PM

You pinged me earlier.

oh, was about the "rapidly changing event" notice on the CRWEC meta-post. We're thinking of rebooting CRWEC but making it monthly instead of weekly; would it still require the notice?

« first day (270 days earlier) ← previous day next day → last day (3752 days later) »
