I am trying to reproduce the answer provided by chris to mathematica.stackexchange.com/questions/16375/… using 10.2, yet I can't get the same answers. would someone mind checking with their version?

I need exactly 3!!!

@halirutan fixedish I think someone else also voted.

@William I hope with exactly 3 reputation points :-)

Damn.. now I need to wait another 10k points..

I remember playing this game with someone. We ended up downvotes and stuff it was exhausting.

Hi, could anyone test the example "Create a maze by random depth-first search of a grid graph" in the FindShortestPath page? It gives me an error "Set::pvw: "The property value PropertyValue[{m,v},VertexCoordinates] could not be set.""

@MartinJohnHadley Sorry, my R knowledge is quite limited, and I don't know that off-hand. Also sorry for the late response, I am not at home and my internet access is spotty.

@xslittlegrass Agreed. Related to mathematica.stackexchange.com/questions/94277/… ?

@Szabolcs no worries, thanks for reply :) I asked 'cus I've been using some of your nice stuff here szhorvat.net/pelican/pages/mathematica.html after you answered one of my questions on multi graph

@MartinJohnHadley @Szabolcs The analog of Apply in R is do.call(...). Look it up, e.g. here.

@LeonidShifrin that's wonderful, thanks! I didn't ask you out of embarrassment in having never learned R when I promised you that I would :D ... finally getting round to it now.

@LeonidShifrin Well, actually I used that but forgot :)

@SjoerdC.deVries have you tried email?

@Szabolcs Hi!

A comment I've found out there:

Thank you clive – Clive elphick 22 secs ago

@Szabolcs My last email sent to @Guesswhoitis. a week ago hasn't got reply yet.

@belisarius What does that mean? A man who is talking to himself?

@Silvia I guess he just forgot the stop "Thank you. Clive", but it's funny :)

@belisarius Kind of cute :)

@belisarius Here in East Asia, we call that Moe :)

@Silvia Do you know why there are so many new (college?) users from Asia each year? Is Mma a standard curricula somewhere?

Most of them never return after the course

So probably it's useless for them

@belisarius Could be in two or three colleges/universities in mainland China. I'm not sure. And I don't know the situations in Japan or Korea.

@Silvia India seems affected too :)

@belisarius Oh yes could be. India has huge CS students!

@Silvia It seems odd to train students on a non-free platform. There are a lot of good free stuff to learn out there

When I was in college, there is indeed an optional course on introducing MMA.

Oh, optional is OK

@Szabolcs Not yet, will do tonight if nobody else has done so.

Hello everyone

I have the problem, that the user interface and all the text in mathematica is unsharp

like using a bad printer

@DominicMichaelis I'm afraid I don't have a clue. Never had that issue. What OS are you using? No problems with other programs?

@Szabolcs Sent

@SjoerdC.deVries Windows 8.1 Pro, nope in every other program everything is sharp

my resolution is 1920x 1080

the quality of the upload is not the best, on the left hand side something is written in win edt and on the righthand side it is mathematica

I hope you see a difference

I have zero mathlink experience. I have some (crappy) C++ function that I want to call from Mathematica (from Linux). What's the easiest reasonable path?

Mathlink, librarylink, etc? and if so. Any particularly good tutorials/examples?

Disclaimer: I haven't tried anything, not even pressed "F1"

@Rojo mathematica.stackexchange.com/questions/8438/… ?

@DominicMichaelis The difference does not seem to be large, but I assume it's worse behind your screen. Did you adjust Window's color profile in the control panel?

bloch thaaanks

:)

@DominicMichaelis in which case it might be related to mathematica.stackexchange.com/questions/87072/…

@SjoerdC.deVries yes it much worse here

I tried the color adjustment but nothing happens

@DominicMichaelis Anything non-standard that you did? Changed any Mathematica or Windows setting? Which version are we talking about? Has it always looked this way?

@SjoerdC.deVries it does look like this always on this pc, i Have mathematica 9.0.1.0 on a windows 8.1 pro operating system. On my old machine the fonts did look better

what dpi have you set in Windows?

Is 1920 x 1080 a possible answer ?

it is a 15,6 inch display

@DominicMichaelis it's a software setting I expect either 96 or 120 dpi

where do I see it ?

I'm not sure. It might be that that was an XP setting. But if you go in the display control panel (perhaps advanced options) there are various scaling and dpi options. You might try those. Perhaps there is a conflict with an assumption made by mathematica

I don't find an option to change it

In Win 7 There is one tab to scale screen items 100/125/150%. There's also a "Set custom text size (DPI)" option

In windows 8.1 there is just a factor which may be set but nothing with dpi

@DominicMichaelis seen this:

support.microsoft.com/en-us/kb/2900023

?

@SjoerdC.deVries not yet, I start to read it

@SjoerdC.deVries oh thanks a lot, now everything is fine, you are my hero :)

@DominicMichaelis Glad to be of help

for sure it is only a small problem but it did drive me crazy at least a bit

I contacted the mathematica support and they told me, it is best to contact wolfram community, that disappointed me a bit

@VitaliyKaurov "Very active thread"? I see one today, a couple 3 months ago and then the remaining 99% 1 year ago... doesn't seem very active to me ;)

Also, some indication from WRI developers that typing into the textbox on that page is more useful than typing into /dev/null would also be helpful :D

@TheToad I got 6 or so emails today about that thread from Sander Huisman mentioning functions that were recently added.

@TheToad true )) what I meant there are many comments and ideas. WRI folks monitor it.

@DominicMichaelis This is normal. Many many Windows programs don't support DPI scaling. Mathematica is hardly an exception.

@TheToad There was a burst of comments today.

@Vitaliy But I still want bugfixes and polish over features ... I have no need for more symbols in the system namespace. Instead make those that were added fast and robust, and complete any missing features. For example ArrayResample is literally unusably slow for multidimensional arrays. It's much faster to use Part, which can do the exact same thing. For some reason, ArrayResample uses a convoluted implementation that does the same thing much more slowly and at the cost of unpacking.

@Szabolcs In fact i didn't know that something like that exists

It should never have been added like this. What happens is that I look at it, I try to use it, I discover that it's broken, and I won't touch it for quite a while. I might not even notice if it gets fixed in the next version. I think other users will behave similarly.

What I'd like is: have the Property system for Graph fixed and made usable; fix NeighborhoodGraph and make it not compute the layout for no good reason (which slows it down more than 100 times); make BetweennessCentrality take weights into account like EdgeBetweennessCentrality does. Fix Graphs with properties getting corrupted when deleting edges or vertices. Fix nasty inconsistencies like the ones between WeightedAdjacencyMatrix and WeightedAdjacencyGraph. Why on earth do these two ...

does someone how this was fixed?

... have to use different and incompatible adjacency matrix formats?

@DominicMichaelis What do you mean?

@Szabolcs it was a very strange mistake, because changing a variables name changes a working code in a non working code

the "this" is a link

@DominicMichaelis Check the link in Mr. Wizard's answer for why some functions are sensitive to variable names.
