I had some fun making a blog for one "Steve Wolfraum" in under 30 minutes: wolframcloud.com/objects/b3m2a1/home/…

If anyone wants the email steve.wolfraum@gmail.com let me know

@b3m2a1 Nice blog post, I'll let someone else have the email though ;)

@b3m2a1 Are the meeting times consistent? I never paid attention, I occasionally tune in when I get the notification email, look at what's planned for that day, and usually just close it (as most of it is not sufficiently interesting to watch live)

b3m2a1

@Szabolcs Looks like they might cluster towards being on the hour? But other wise no pattern that I see from the feed timestamps here.

And if you look at the videos the vast majority of them don't really start until ~25 minutes into the stream

If you really want to catch it, you can keep the thing open in the background and wear headphones? I think it's silent if nothing is playing and so that'd alert you immediately when it starts.

Szabolcs

I might not be able to make it. I would probably be difficult to make a difference by commenting. I can still watch it afterwards and see what's happening.

So thanks for the note!

b3m2a1

Oh actually I just realized I have Twitch email me when it happens from before the addition to the feed here. Here are some timestamps:

All those times are PST

@GalAster nice to see you here. Did you see my comments here?

Hopefully they were clear enough to be useful

BTW off-topic: Did anyone upgrade to Mojave and did you find any unexpected incompatibilities (Mathematica or other software)? I'm not planning on upgrading until 10.14.1, but I'd like to know what to expect.

@CarlLange had some advice about it breaking things in Safari I think

@J.M.issomewhatokay. do you have a package of your numerical recipes for special functions laying around somewhere? I notice you seem to have a nice recipe for most special functions-related things that appear here, but I'm not sure where I could access any of it outside of your various answers and blog posts. Even if it's not polished up or documented I'm sure people would find it useful to have on GitHub in whatever form.

J. M. is somewhat okay.

@b3m2a1 I said this in my blog post:

> So, I am now actively working to document or finish some of the stuff I had been developing and keeping for years. I am really hoping what I can produce over the next few weeks would be useful to a lot of people.

my special function-related research is part of what I'm working on to release gradually

Mostly, they need to be documented, and made a little more user-friendly

a small number work for most arguments, but break spectacularly in some corner cases; so, I still need to research fixes for those as well.

Carl Lange

@Szabolcs Safari 12 breaks the SE editor bar extension. Mathematica gives a warning when you open it that it's only 32-bit. Those are the only two issues so far.

(Also my Emacs build broke, but you probably don't care)

Warning only happens the first time you open MMA and every 30 days, I think. 12 should fix that issue.

@CarlLange Every time or first time only?

@CarlLange Sorry, I just saw that.

Would love to know if anyone has any info they could share about GrammarApply and related functinos mathematica.stackexchange.com/questions/179762/…

functinos is the name of my next subatomic particle

Szabolcs has made a change to the feeds posted into this room

Szabolcs

@C.E. I added the PackageData RSS feed to this chatroom. It's low volume, and it's useful to learn of new additions. It also strengthens community moderation. Is this OK?

What is the difference between PackageData and the PublicPacletServer?

C. E.

7:34 PM

@Szabolcs Yes, I think it's a great idea.

b3m2a1

@KraZug different installation concepts. PackageData links to packages where the PublicPacletServer tries to host the packages themselves (as paclets) for ease of installation.

The idea for the latter was to build something like the PyPI and to get pip-like installation.

Szabolcs

@C.E. For the above question: didn't you have a meta post about PackageData? Or was it all here in the chatroom?

Can't find the meta post now.

C. E.

@Szabolcs It seems like it was all here in the chat room

Szabolcs

@KraZug Do you know MathSource (recently, or many years ago, renamed the Wolfram Library Archive)?

library.wolfram.com

halirutan

@Szabolcs There was some kind of trick to prevent that all the old RSS messages are displayed when adding a new feed, but I don't remember the details. Maybe RM or CE or MrWiz told me about it.

Szabolcs

7:46 PM

@halirutan Yes, put it as a ticker feed, wait for the flood, then change to message feed

halirutan

Ahh, right. Exactly

Szabolcs

I did that but I was impatient ... didn't wait for them to appear. I wasn't sure I remembered right that they would appear.

@KraZug If you search the Wolfram Library Archive for packages, then often there's no source code, only a reference to a conference presentation; or the package is 20 years old and doesn't work anymore; or it's not even a proper package, just some notebooks; or the package source stored at the Archive is not the latest version

Submitting is also somewhat difficult, and takes a couple of days. The submission should be a proper package (hopefully), not a work in progress.

Updating a submitted package is too much fuss so people don't do it.

I like PackageData because it solves many of these problems.

It's just a collection of links, but it's very easy to add packages to it, it's easily searchable, it's just packages, and it's moderated by the SE community (you need 2000 rep and you can log it with your SE account)

People can also add GitHub links to something that is not quite a version 1.0 yet, but they still want to show it to the world and maybe gain some collaborators

It also has the RSS feed, so now we can see updates here immediately (and moderate if needed).

So, at least for me, PackageData is a fresh and dynamic replacement for the Library Archive

It's not a package repository like PyPI, which would take a lot more effort to make succesful

halirutan

I hate to interrupt with something completely different, but does someone know how this kind of chart is called?

junkcharts.typepad.com/.a/6a00d8341e992c53ef01a3fbbe5a13970b-pi

KraZug

@Szabolcs, ok, thanks. Yes, I've seen MathSource, and never found it very useful. I have my package on the PublicPacletServer, but I should probably put it there too.

Szabolcs

@KraZug You can add a link to whereever is the main website of your package.

I was really curious about this graph meeting, but it's getting late ... not sure I'll wait for it

KraZug

8:00 PM

@b3m2a1, can you remind me how to update my paclet on the Public server?

C. E.

@halirutan Searching for "hierarchical edge bundling" gives similar results (I recognized the plot from the d3.js example gallery, and that's what they call it.)

b3m2a1

@KraZug provide a link in an issue to GitHub or similar and I can update from there.

Szabolcs

@halirutan I don't know :( Circular graph layout with edge bundling? Although there's not much of a bundling in that one.

b3m2a1

Basically just ping it with an issue and we'll go from there (I don't have so many submissions that I need to automate the handling).

Beyond, I suppose, the large amount of automation I already do

@Szabolcs It seems to be related to Sankey diagrams but "circular flow chart" gives also many hits..

Ah.. "Chord diagram"

KraZug

@b3m2a1 Heh. I thought I'd updated it via the package before though

b3m2a1

@halirutan I always read "Sankey diagram" as "snakey diagram"

@KraZug ah yeah there's a way to do that but I can't remember

Give me a moment to look it up :)

Szabolcs

@b3m2a1 Me too! It looks like that :D
