OMG, how very beautiful ! Is it fully automatic? Will it persist?

Yes, here is info: https://stackoverflow.com/questions/33225947/can-a-website-d...

Selenium leaves trace in HTTP requests, so its use is quite detectable. The authors of PeopleSoft can include Selenium detection in their products, disallowing your automation scripts. Why not use GreaseMonkey instead?

I want to share my solution for remote collaboration and teaching: https://github.com/amkhlv/mathpump3

Professor uses Wacom and Inkscape to draw a picture, which is incrementally transmitted to students' computers. Students, those who have Wacom, may interact. Or just watch. Transmission happens every time the svg file is saved. Transmission requires a RabbitMQ server, which can be easily set up. Basically, a class needs one person who knows Linux, to set up the server.

It is intended for scientific collaboration or teaching in small groups of people. I am now using it for teaching my QFT class, although it only has 5 students. In principle, it should scale, but I have not tried it for large groups...

Drawing with Wacom in Inkscape is a pleasure, once you get used to it. In some sense, it is more convenient than using a physical blackboard. Although, some training is needed...

Right, because computer programming (unlike computer science!) does not take a genius. It is, basically, a routine work. Unfortunately, there is a tendency to say the same about fundamental science, for example here: http://www.slate.com/articles/health_and_science/science/201... and here : https://www.theguardian.com/commentisfree/2017/sep/30/we-hai... This worries me. Without outstanding contributions from individuals, science will turn into waste of human resources. We absolutely need to protect and care about our elites !

exercise is great, but one has to be careful, and avoid doing stupid things:

It seems that such exploit would require some kind of `network-manager` running. But if `network-manager` is disabled, and all interfaces configured in `/etc/network/interfaces`, then the new malicious interface will be just ignored. It will not come up.

Right, but a custom HTTP header does not even have to contain a secret. I just has to have a non-standard name. Firefox will refuse setting it, right?

Perhaps a server, when running in development mode, should require a custom HTTP header? This would be a non-simple request, and the browser will refuse. Would this be a reasonable counter-measure?

Here in Brazil, all NATs are either defective or ``symmetric'' whatever this means I am not an expert sorry. I do not expect STUN to work. As for TURN, this means traffic will go through the server. Then how is it better than Skype? Microsoft can afford, if I understand it correctly, a huge network of TURN servers, essentially. Is this how Skype works?

STUN server is not a real solution. It is typically unable to penetrate NAT. Maybe WebRTC will work sometimes, but it is not a reliable solution. It is difficult to come up with alternative to Skype until IPv6 is widely adopted. But when we get IPv6, every computer will have its own address, then yes.

Dear William, thank you for your great work! My post was sarcastic. I completely agree with what you wrote in your comment. But I do believe that my guess about why your proposal was rejected is partially correct.

"making only some software available in US" --- you slightly missed my point. I meant "software only available in US". That would be impossible to achieve with Sage, as Sage is open source. If you support Sage, you cannot control who gets it. (By the way, North Korea would also be able to use it!) The point, I believe, is to only support those projects which are under control and can be used for control. Maybe I am unfair to Simons. It is just hard for me to interpret this in any other way. It is not only about software. Academia has other structures serving the same purpose.

Academia needs some control mechanisms. Otherwise, the scientific research is at risk of becoming completely chaotic. Selective availability of software is one of those mechanisms. In this case, a closed-source software is made available to a specific group of people controlled by highly competent leaders: the US academic community. This increases the prestige of the group, and indirectly the level of competition needed to get there. Moreover, it increases the prestige of the US universities. This also helps the world-renowned science leaders to have more refined control over the direction of scientific research and science policy.

I developed this: http://andreimikhailov.com/slides/bystroTeX/slides-manual/in... and it seems to work, for example: http://andreimikhailov.com/teaching/gdmc/exterior-calculus/i... I wish I had time to polish it more. It is also Scribble, but unrelated to Pollen.

It says ``This video can’t be played with your current setup'' I guess must be some super-advanced new audio-codec. Please, recommend me how to get around this restriction!

You are right, and thank you for the link. Actually, let me use this to advertise my own fork of PdfViewer:

https://github.com/amkhlv/pdfviewer

I started that fork because I could not find a viewer which would keep vertical position, and jump back after following an internal link, and have bookmarks with charhints.

There is a conceptual problem, however: as I said, I feel that PDF is getting deprecated because of insufficient demand. If this is true, then it does not make much sense to invest effort into TeX + PDF. Maybe I am wrong. Sometimes I think that I am simply allergic to TeX :)

Also, if they submit a revised version, it will be a different page. Anyway, I don't think we will ever get a good PDF reader, because there is no demand. People read HTML.

I dont know what is Adobe plugin. I will investigate. However, just based on its name, I would probably recommend removing it. The combination of these two words, ``Adobe'' and ``plugin'', makes me feeling uneasy :) Which brings us to the second point: there is no good open-source PDF viewer. If you care about using open source, then go HTML.

Thanks for the link, I will have a look! Although, in terms of typography you cannot beat LaTeX. That's what LaTeX is good at. But the thing is, I don't care so much about the typographic quality. All I need is a quick way of inserting and hyperlinking math formulas in HTML pages.

I want to put a hyperlink to Eq. (4.4) of http://arxiv.org/abs/hep-th/9907164 What is the right format? How can it even in principle work? If I click on the link:

http://arxiv.org/abs/hep-th/9907164/Eq_4_4

what is supposed to happen?

The main problem with LaTeX is that it does not have a good hyperlink mechanism. So, I am thinking about how to switch from LaTeX to HTML. I have a markup system based on Racket:

http://andreimikhailov.com/slides/bystroTeX/slides-manual/in...

The main application was supposed to be slides, to replace the Beamer. But I think it is good for generic math-oriented web publishing. It does not work on Windows, though. Comments/suggestions/testing are welcome!
