:) that's true. In case we actually get questions for which adding the tag would be useful, we could introduce it, but up to now there have not been any.

tohecz replying to samcarter

ah, but then I don't need to worry about the email feed either :D

samcarter replying to tohecz

You don't have to worry about (1) yet, as the `overleaf` tag does not yet exist :)

tohecz replying to samcarter

ah cool!

tohecz

Ah, well, that's a nice offer, thanks! Basically what we do on SE: (1) If the question is not Overleaf-specific, we untag it. (2) If it's specific to an Overleaf project without any obvious community benfit, we direct the user to the support at company email address. (3) If it's Overleaf-specific, but more generic/conceptual, we try to address it in the post as that is beneficial to the community (sometimes it requires to go to email too as the user can't separate the conceptual issue from their personal contents, but that's the next step).
  
The things under (3) are most interesting obviously to me/us, as (1) is just a mis-tagged regular post, and (2) needs to go to emails either way and hardly anyone benefits from it.

@tohecz Recently your overleaf drawing contest came up in the discussion to  https://topanswers.xyz/tex?q=1570 :)

samcarter replying to tohecz

In the mean time, I can play your personal newsfeed if you want and ping you in case anything overleaf specific comes up.

samcarter replying to tohecz

:) Comments are indeed a bit different than on other sites and probably take a bit to get used to. The big advantage is that it is much easier to discuss about a question or an answer. One has all the features of a real chat room, can reply to specific comments, show code blocks including proper syntax highlighting etc.

tohecz replying to samcarter

not sure I wanna go that path. Enough of all the internal Overleaf feature requests I make :D But thanks for letting me know! (I'll actually make a note about this if I feel like taking up the challenge one time!)

samcarter replying to tohecz

Not yet. The closest things available is an RSS feed for all new questions from the TeX community. However If you would to make a feature request, head over to the tavern https://topanswers.xyz/meta?room=1

tohecz replying to samcarter

oh hi Sam Carter!

samcarter replying to tohecz

Hi, nice to see you here!

tohecz

I wonder, does TopTeX has email feeds for tags? We find it useful at Overleaf in SE, for email notifications about messages tagged [overleaf], so I wondered whether that’s not available here as well…

tohecz

Ah I see, the "Chat" changes to "Comments" whenever you're not on the dashboard (so not even in help pages). I don't consider that intiuitive :-) Anyway, here's the message:

tohecz

Heck, I posted a chat message just about 10 minutes ago. I saw it being here. I refreshed the page, and the message has disappeared.

"Value added" services have always been accepted and permitted.  For example, the PCTeX and BlueSky implementations of TeX, which involved considerable work to accomplish, were both recognized and accepted by Knuth.  I'd say that Overleaf's services are acceptable under this criterion -- what is provided here is use of facilities and enabling of cooperative work by subscribers, as well as support by knowledgeable individuals paid for their work.  
I don't know the details of the tool based on TikZ, so won't try to judge.

Happy rubber duckie day to you too!

Diaa replying to Anonymous 1123

I don't see it is different from building a program in C language for example then sell it.  
You don't have to pay to learn C but you can legally monetize your knowledge of it.

marmot replying to Anonymous 1123

I think it is legally allowed. If it is morally the right thing to do is another question, but recall also that Overleaf is basically doing the same: they sell online compilation LaTeX services. Different people have different views on whether this is something one should do. My personal take is that Prof. Knuth and others offer us all these tools for free and it is at least questionable if someone provides services entirely reliant on these free tools for profit.

Anonymous 1123

I heard someone base on TikZ to create a tool, then sells this tool. Is this allowed?

Is there anyone who has enough knowledge with both linux and windows to help me with my question https://tex.stackexchange.com/q/578144/2288 before importing it here?

Raaja replying to Prabhjot Singh

Thnx

marmot replying to Diaa

It is not a LaTeX package but just Mathematica. https://www.wolfram.com/mathematica/

Diaa replying to marmot

Would you please share its link? I couldn't find it.

marmot replying to Diaa

In my humble opinion there is only one package which deals reliably with most mathematical operations, and this is Mathematica. The LaTeX support of this package has considerable room for improvement, but at least in principle there is some.

Diaa

Does anyone know a package that enables doing complex mathematical operations (except sage) without the need for external compilation from another software?

Prabhjot Singh

btw A happy and warm year to all of you.

Prabhjot Singh

 [link](https://adityam.github.io/context-blog/post/interfacing-with-julia/ ) for latex and Julia. :

Raaja

Idd that's true, but I would also like to know your experiences with it (if any).

marmot replying to Raaja

I have no experience but if you google `julia pgfplots` you get several hits such as [this one](https://juliapackages.com/p/pgfplots). I believe to vaguely remember having seen some questions on this in TeX.se.

Raaja

I recently heard from one of my colleague someone made a nice interface between latex and julia so that julia can use latex to make plots. Does any one of have heard/used it in julia? PS: Julia is a programming language.

Anonymous 1123 replying to samcarter

Yes. It  is a matter of philosophy imho. I use the way to teach secondary school.

Anonymous 1123 replying to samcarter

Thank you very much.

samcarter replying to Anonymous 1123

You can also write `\SI{0.5}{\kilo\metre\per\hour}` - which one to use is a matter of philosophy imho

Anonymous 1123

@Joseph I  use `siunitx` package. Am I true when I type  $\SI{ 0.5}{km/h} $?

Very reasonable given that marmots are hibernating in their burrows. :smile_cat:

samcarter replying to barbara beeton

Amazing story! Thanks for sharing the link! It is so refreshing to read news about happy people. Nice that a little bird can bring so much joy to all these people.   
I recently listed to a podcast about life in Paris during the pandemic. During lockdown a lot of different birds have conquered (back) the city and the podcast said that many people now picked up bird watching as their hobby :)

barbara beeton

@samcarter -- When I first signed up here, you asked what I had chosen for an avatar, and I identified it as a painted bunting.  Well, here's a report of an actual sighting, much out of normal range, and the poor thing is all fluffed up on account of the cold: https://www.washingtonpost.com/dc-md-va/2021/01/03/painted-bunting-great-falls-bird-watchers/

You're welcome! I think one can improve it by using a `standaloneframe`. (Interestingly it seems that an `xsavebox` eats the fadings.)

... but it does show that the answer you got is a tiny bit off, and that it is possible. Now one would have to prettify things. (I think `makecell` does such things but I am not sure.)
