I posted something on unix.se about a Mathematica related issue, if any of you have any idea please let me know :)

http://unix.stackexchange.com/questions/136396/clipboard-behaviour-when-copy-paste-from-mathematica-to-gooble-chrome

12:17 PM

@Öskå You should have asked here first :-)

@Öskå I guess you are using Chrome (no matter whether beta or stable) and not Chromium?

Yes I'm using Chrome indeed

@halirutan and I still can Copy/Paste on here.. :) But last time I had a clipboard related issue you advised me to ask there.. :D

@Öskå It depends on the whether in Oslo..

@Öskå OK, here we go:

I didn't get the Oslo joke :P

I can ask a proper question on mma.se if you like :)

I'm just going to copy/paste the same question

@Öskå I could have said it depends on some water level in China.. I just mean I know the answer in this special case and what you did (asking on Unix) was the correct way in general

That's why I asked on the chat here as well :)

12:23 PM

@Öskå I suspect the issue is related to the java one I reported here. This all comes from Mathematica which rapes the system clipboard by not ending the copied text with a zero byte.

Oh lord, now I remember you giving me that link last time.. :)

@Öskå After the last update, Chrome unfortunately shows the same behavior. I haven't found another way than using Chromium instead of Chrome.

@Öskå If you have time, you could post an issue on the official Chrome bugtracker.

mhm, I might do that indeed, it's really annoying. But when doing xclip -out I get Error: target STRING not available after copying something from Mathematica.

So is it Chrome-related or Mathematica/XClip-related?

@Öskå This is what I get after copying your code in Mathematica

xclip -o -verbose -selection clipboard | hexdump -C
Connected to X server.

Using UTF8_STRING.

If I copy: StringJoin @@ CharacterRange["a", "z"][[;; 14 - 2]] I get:

@Öskå Now copy the input not from within Mathematica but from the chat-message above and do the same xclip command in a terminal.

You will see that there are no additional bytes after the 2]]

Indeed, so I guess that Mathematica is f*cking things up and Chrome can't handle it? I have no clue how I could report that tbh :)

@Öskå It needs to be fixed at Wolfram. I already did this for the current beta but I wouldn't hope for much..

Let's not lose hope :D

But @halirutan thanks for your help, at least now I understand the issue :)

@Öskå No problem. Glad that my wasted hours save some one else's time.

12:55 PM

I bet you had a better understanding of what's internally going on thanks to that, which makes it worthy.., r-r-r-ight?

1:34 PM

@Öskå Only if I can fix it, which I can't in this case. I still have to live with the fact that each bit code I copy from Mathematica to IDEA has trash at the end.

rm -rf

@SjoerdC.deVries I agree with you in general, but here, it seems fairly innocent and nothing sinister. OP must've had a "oh duh!" moment and deleted it. Since there are no answers and there are plenty of possible duplicates as you say, I'd suggest just leaving it alone. Perhaps if the comments required more effort (e.g. a comment saying "I tried this for a while and here's an outline of the algorithm; I'll post an answer shortly") then we could undelete it.

@rm-rf OK, I can agree with that.

@Rojo Did you use it, or do you just feel close to its name? :)

Hi guys, for some reason ParametricPlot3D isn't showing all the longitudinal mesh lines: i.imgur.com/wxZVTvA.png Any idea what could be going on?

@Guillochon Can you try what Mesh->Full gives you?

IMO the automatic mesh generation is messed up. Just look what ParametricPlot3D[{Cos[u] Sin[v], Sin[u] Sin[v], Cos[v]}, {u, 0, 1.9 Pi}, {v, 0, Pi}] gives you and that the missing line is exactly where the sphere closes at 2Pi.

@Guillochon `ParametricPlot3D[{Cos[u] Sin[v], Sin[u] Sin[v], Cos[v]}, {u, 0,
2 Pi}, {v, 0, Pi}, BoundaryStyle -> Black]`

anyway its the boundary and not the mesh

@chuy I'll try that, waiting for some cells to finish first

@chuy Exactly! It's really weird this is not the default when half of the examples in the doc are closed toruses or something else where this issues shows up.

@chuy Splendid, that works! Thanks.

chuy

I can see the sense in it not being the default, but view may vary

Rojo

5:02 PM

@Szabolcs The latter :)

5:43 PM

Another quickie: Is there a way to change the line thickness for BarLegend? The lines/ticks are hairline thin and difficult to see

Szabolcs

@Guillochon I don't know, I can't find a way either.

@Guillochon Try digging in Options[ChartingiBarLegend]` ... TicksStyle affects colour but not thickness.

(I think)

@bobthechemist You asked me some time ago about Joomla. Do you have any further experience? For instance, tweaking the JCE editor so that inserting the <pre class="prettyprint"... becomes easy?

I'm not satisfied with my knowledge about Joomla. In general it is a great system, because it is easy to use, but plugin/extension/modules is kind of hard to understand at the beginning. For instance the JPrettify plugin I recommended makes nothing more than inserting in each page that the prettify.js script is loaded so that you can use the highlighting. This is kind of overkill and I would really like to know how to tweak things and do stuff by myself.

@halirutan I haven't had much luck with the extension, and was planning on following up with you. Regardless of the the type of code (python, bash, WL, etc) I get no highlighting but do get grey-background code. The project went to the back burner for a while. I agree that the extensions are quite cumbersome - better in Joomla 3, but still a pain. I looked at Drupal and Wordpress as alternatives, but it wasn't obvious that they made the task simpler.
