@Szabolcs I came into trouble with dynamic histograms in v9 a while ago and didn't check if v8 had the bug too. However, your issue was different, but I tell you because you seem to be using histograms dynamically
@Szabolcs They use some internal symbol which gets tracked so it constantly reevaluates it even when it doesn't need to. I reported it and got a quite dumb respose. I just used, instead of histogram, safeHistogram = Refresh[Histogram[##], None] &
@Szabolcs Just try With[{d = RandomReal[{-1, 1}, 10000]}, Dynamic[Print@3; Histogram[d]]] to see what I mean
Its subtle because you won't actually get bad results, just slow and CPU wasteful ones

@Rojo What is dynamic histogram? Are you referring to the mouseovers?
 
@rm-rf No
Just to a histogram inside a Dynamic
A histogram that gets updated when something happens
Data changes, etc
 
ah, ok. I thought it was new functionality in v9 =)
 
@rm-rf No, it's the contrary. I just tested in v8 and it worked fine
A v9 screwup

@OleksandrR. what the hell? What did he do?
 
1:59 PM
@rcollyer spamming
 
2:48 PM
@OleksandrR. well the 15 year ban should work, maybe ...
I hadn't noticed any spam, but we're very quick around here.
Should we add a snippet on the blog about this: Free fall steak?
 
On second thought, never mind.

Is there a way to get LayeredGraphPlot pick up the vertex styling of a Graph?
trying to make a "family tree" type graph, with pictures at the vertices
i have a nice Graph but it's not layed out as nicely as the LayeredGraphPlots
should i ask this as a question?
 
@EliLansey Sorry, I can't help with that. (v7)
 
@Mr.Wizard oh well.
you'd think that with 44k rep wolfram would gift you their latest and greatest version, you know?
 
@EliLansey makes me wonder about holding a contest. Thoughts, anyone?
 
3:38 PM
A contest seems to not really fit with the site since even theme questions are sometimes frowned upon, but it would be a great match for the blog in my oppinion.
 
3:51 PM
@jVincent that is a good point, but other sites, such as Ask Different, have had contests in the past. Besides getting SE to pay for a full license seems like a nice idea to me. But, it may not be others cup of tea, so I asked.
 
I personally would like to see both just theme treads and competitions (with or without prices really). But I get the feeling most don't agree, in any case start a thread on meta and see what the feedback is.

I participated in the apple contest (and won an ipod) and it was very nasty... voting nearly shut down unless it was a true diamond of an answer. On the last day, people started strategically downvoting others just to get ahead in the race
We can pitch the idea, but it's not very likely that they'll agree to sponsor... In any case, we need to come up with our own format that minimizes an individual's ability to strategize for personal gain, while giving every one (regardless of rep) an equal shot at winning something
I say "they'll not agree to sponsor" because they usually try to tie to some major event related to the site. I asked about it during v9's release, but they said that they were going to be busy network wide w/ hats and general sluggishness due to the holiday season. Maybe next conference? There's also this:

Q: Should we hold a mini-contest?

F'xEdited now that the site has graduated: How do you feel about holding a Mathematica mini-contest? It seems to me that this is a great fit to our community’s overall “we find plenty of ways to do stuff” spirit, and it could help publicize our site in an effective manner. I'd be willing to step up...

One of our New Year’s resolutions here at Stack Exchange is to take a hard look at our user experience. As the network has grown and our audience expanded, the system has grown with it – but there are some rough edges in places that can use a bit of smoothing. You’ll be seeing a lot of improvements over the next few months, but today I’d like to announce the first bit of polish: built-in profile pictures.

We have used Gravatar to let you manage your profile picture since roughly six to eight weeks before Stack Overflow entered beta. Gravatar is a wonderful service that lets you use a con …

 
@rcollyer That must mean we're doing our work pretty well =)
 
@rm-rf actually, your experience on apple.se is enough to dissuade me. I'd rather not have it turn into a blood bath just to get Mr.W a free copy of v9.
@rm-rf and, the users here are really kind of rabid about that sort of thing.

Q: Can we automate spam detection in the suggested edits?

rm -rfWe occasionally get spam in the suggested edits like the following: The entire post has been defaced and replaced with spam. This is not an isolated occurrence; here are more examples: 1, 2, 3, 4, 5, 6. All of them have the same characteristics: Not a single word that can be found in the Eng...

any one uses Mathematica on Linux here by any chance?

@rcollyer Congratulations! :-)
@rcollyer It was my mistake. I'm not sure what I did that brought up a window asking if I want to disable dynamic evaluation (it was taking too long), so I did disable it. After that I restarted the kernel a number of times, and I didn't realize that this didn't really reset the system. Dynamic Evaluation was still off because I didn't restart the front end. I also didn't realize that if Dynamic Evaluation is off then histograms with only a few bins do not work.
So all in all it was a user error.
You can try Histogram@RandomReal[1, 100] after turning off Evaluation -> Dynamic Updating Enabled, and it'll give you a grey rectangle in the middle of the graphics. But I think this is normal, not a problem.
This is an excellent suggestion, I've been using it a lot recently (as I needed to use Combinatorica):

A: How to load a package without naming conflicts?

Leonid ShifrinThe answer of @R.M. already explains the essence of the problem. You can streamline the process of removing the Combinatorica from the $ContextPath by loading it via Block[{$ContextPath}, Needs["Combinatorica`"]] (or use Get intead of Needs, although Needs is a preferred way to load a package...

@WReach @rcollyer Here's the same thing in the current documentation. It wasn't that easy to find ...
 
8:18 PM
@Szabolcs at the very top it says "OBSOLETE MATHEMATICA TUTORIAL" So it is likely a rehash of what was already discussed.
@Szabolcs thanks.
@Szabolcs I'll have to play with it a bit. What version are you using?
 
8:42 PM
@rcollyer 8 or 9 do the same thing, but as I said, it's really not a bug.

@Szabolcs In fact, it is the exact same page :)

@Nasser yep. Windows & Linux.
 
@Rolf, thanks. I was away. I am on linux now, But I do not get the main bar at the top like on windows. I am just evaluating linux and using a 30 days trial version of M9. Do you also not get the main top bar as well? THis is strange it is missing. I assume this is only in a trial version that this happens?
 
@Nasser. Yes, I also do not get a main top bar. There never was such a a thing. It still looks like here upload.wikimedia.org/wikipedia/commons/thumb/3/3e/…
