@R.M. @Szabolcs Usually I would post this in the plugin chat, but I'm very happy at the moment and I think everyone should know about it.

We got another high-end (and expensive) tool completely free of charge for the Mathematica Plugin development: The YourKit Profiler!

I used a test-version lately to track down some bug and I was instantly in love with it. In only a few minutes I could track down the 20 lines of code (out of about 12000) that were responsible for a performance drop in specific situations.

I wrote the guys who sell it whether they would support our open-source project and today I got the confirmation mail that they are all in.

This is btw the second company that gives expensive things for free. We already have IDEA Ultimate licenses for the plugin developers for free.

@halirutan Congrats! This is a top-notch tool. When I started my switch to programming, they were the first company I did my interview with. They gave a take-home task of writing a virtual file system in Java, which I did, and learned Java along the way. They ended up picking some other candidate, but they told me that my code was more professional than most of those they got from candidates with years of experience.

@halirutan In fact, at the time (2009) they were just 2 or 3 guys - I mean, the developers. One of them, IIRC, previously founded IntelliJ, or was one of the founders.

@halirutan Their dev office is also in SPb, like IntelliJ

halirutan

@LeonidShifrin I guess many of the guys around IntelliJ do know their stuff pretty well.

@LeonidShifrin The HQ is in Germany, actually :-)

Leonid Shifrin

@halirutan I think so, yes. They have some amazing folks there.

@halirutan Why am I not surprised :)

@halirutan I still want to find the time to open-source that VFS stuff I wrote for them. It had some interesting features not found in usual file system: the clusters could be variable length, and I could insert in the middle of the file or collapse, without rewriting the whole file. For large files, this led to hundred-fold speedups w.r.t. the stanard file system.

halirutan

@LeonidShifrin I noticed lately that your GitHub profile is really empty compared to what you already did.

Leonid Shifrin

@halirutan The funny thing is that this was my first Java program, and yet it is still the most sophisticated and well-designed. And I used Idea for development - this was my first encounter with a modern IDE.

@halirutan Sorry, not following...

@halirutan Do you mean listing some projects etc?

halirutan

12:15 AM

@LeonidShifrin You said "I still want to find the time to open-source..." and I regularly check your repos :-)

Nothing new for a very very long time

It's really sad that you are so busy.

Leonid Shifrin

@halirutan I could explain the reason, but perhaps in an email. Besides, hopefully some time soon I will have a good new installment there :)

halirutan

@LeonidShifrin Or if you like to chat/talk there is still skype :-)

Leonid Shifrin

@halirutan is your email at halirutan.de operational, or should I send it to your uni. mailbox (there are two I have - patrick and patrick.scheibe, there)?

halirutan

You should find me by my username.

@LeonidShifrin Whatever you prefer. My first name at halirutan.de is completely functional.

Leonid Shifrin

@halirutan We could chat now for a little bit, or we could chat tomorrow, which might be better since it's a bit late. But I'd still send you a brief email now.

halirutan

12:23 AM

@LeonidShifrin I'm awake. Can you find me in skype?

Leonid Shifrin

12:33 AM

@halirutan Just sent you an email. Let me look in Skype

halirutan

@LeonidShifrin I invited a Leonid on Skype. Let's hope it was you :-)

I would appreciate if someone could help with the `code`part of formatting in this question

thanks

@OleksandrR. given your post here (demonstrations.wolfram.com/…) maybe you'd like to contribute to the question above?

@LeonidShifrin I'd like to see that code, if you wouldn't mind showing it to me.

J. M. is back.

5:08 PM

@Sosi That's a different Oleksandr. :)

Sosi

oh! thanks @J.M.isback. and sorry @OleksandrR.

can anyone tell me how to format the code part in a post so that it doesn't have that horizontal bar due to the trimming of the code?

i.e. how to word wrap all code and still show the whole thing

Leonid Shifrin

6:04 PM

@rcollyer Sent you an email with the project attached as a zip file. You will have to unzip it and create a New Java Project from its source, in WB. Then run the JUnit tests, the source is reasonably well documented.

rcollyer

@LeonidShifrin Thanks. got it. it should be an interesting read.

I need a little bit of help from someone who is using Windows (or if you like, OS X; but not Linux for now).

Please download IGraph/M specifically from this link, install it as usual (standard package installation), and try that it works. Do <<IGraphM` , then open the documentation, IGDocumentation[], then try a few examples from there. Maybe evaluate the full documentation notebook. Make sure there's no unexpected error, especially no crash.

If you use Linux, don't try it because the Linux binaries are not yet in the archive I linked to above. Only Windows/OSX today. I'll get to Linux maybe tomorrow.

I need an independent test before I release the next version.

Let me know if it worked (or didn't work).

Wolfram Blog: Democratic Presidential Debate Word Clouds

posted on October 14, 2015 by Wolfram Blog Team

The first Democratic debate of the 2016 election season has finally come to pass. Although the Democratic party has less than half the number of candidates as the Republican party, this event was just as lively and saw just as much hype. As we did for the two GOP debates, we used last night’s transcripts [...]

any matlab users here know if there is anything like Manipulate for making simple gui's? About to go into using Glade and whatnot but as a Mathematica user it all seems so complicated

@Szabolcs I'm on OS X 10.11 with Mathematica version 10.2. And I get two errors in evaluating the whole document.

During evaluation of In[30]:= IGraphM::error: games.c:931, No simple undirected graph can realize the given degree sequence

I guess error In[30] is intentional. But these are the lines have errors:

Out[30]= LibraryFunctionError[LIBRARY_FUNCTION_ERROR,6]
