Is there any free or paid WebAR framework that uses images as markers, and not pattern/barcode markers?
I've only found Awe.js, which has some cons.

Is it possible to get alternative image sizes using instagram basic display api? So far I haven't found any possibilities on api doc, but when I inspected instagram web app html source I found srcset attribute which contains several images for different versions, so they exist. Is it possible to get it using the api somehow?
Unfortunately it is not possible with the new API :((((((
I am working on the solution for OCR using Azure Read API, and it provides out of box solution for raster PDFs
https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/concept-recognizing-text#read-api
but I don't see if it can support vector based PDFs. I have other solution by using some third party libraries such as Aspose and PDFxStream, but prefer if I can stay within just Azure Vision API ecosystem.
So my question is is it possible to use Read API for vector PDF, and if not what is best practical approach I could use?
To answer my question: yes, it supports Vector based PDFs, although it is not explicitly mentioned in API documentation. We checked both through Azure portal and through API code and it works. No problem with mixing raster and vector based PDFs.
The educational web app I'm working on makes use of ESRI base maps displayed with Leaflet. (See CODAP and click the Map tool.) One of our partners would like to be able to use a base map that displays biomes as, for example, displayed here.
ESRI supplies a bunch of useful base maps. But how do I create my own? And can I start with an image like the one linked to above?
typically people use either ArcMap or ArcGIS Pro to publish their own content as services hosted either on ArcGIS Online or their own installation of ArcGIS Server, but its also possible to upload shapefiles, csvs and other files into ArcGIS Online directly using the website.

Can anyone indicate me to a framework of BI / OLAP or at least a Chart Engine, preferably open source, which properly integrate with MEAN.JS or MEAN.IO platform in SPA - Single Page Application architecture?
I know the keen.io. It is free in low transactional volume, but it is not open-source.
The Pentaho is a great BI tool, it's open-source, has RESTful Services and supports MongoDB, but your dashboard still employs Java on the server side and is one generation behind frameworks like Node.js and Angular.JS and they are only migrating now for jQuery and Bootstrap.
Thank you in advance for any contribution.
Discovery 1
There is a amazing API, similar to jQuery in objective of manipulate DOM for you to compose graphic charts, named D3.JS - Data-Driven Documents d3js.org.
Discovery 2
There is a chart engine named NVD3 nvd3.org, built on D3.JS, that allow you apply re-usable chart components in your Javascript applications.
Discovery 3
There is a Angular.JS module named AngularJS-NVD3-directives http://cmaurer.github.io/angularjs-nvd3-directives/, that integrate the chart components of NVD3 into directives of Angular.JS, allowing use it natively in your Angular.JS applications.
The Open Source Solution for MEAN Stack
You can integrate AngularJS-NVD3-directives components with Pentaho RESTful services via Mongoose accessing your MongoDB data to build dashboards and scoreboards control panels for your applications.
You still need to write code to integrate each of the components of a control panel as grid layout, themes, field projection and visibility, filter, sort, pivot tables and charts.
Today, the development process of control panels isn't straightforward, but you already have an open source solution good enough to design impressive applications.
I've never used them and may be they're not what you're looking for, but you should definitively take a look to this two projects: d3js and raphaeljs
Hope this helps you!
Anybody here knows which technology or framework or whatever is being used to present that nice GUI on Trello website ?
I'm a little bit outdated about front-end technologies.
Here is a very nice write up of the Trello tech stack from Fog Creek (the creators):
The Trello Tech Stack
In a nutshell (if you're too busy to read the article) they use:
Client
Backbone (for client-side MVC)
HTML5 (for pushState)
Mustache (for templating)
Server
node.js
HAProxy
Redis
MongoDB
On the front-end, Trello predominately uses jQuery and Backbone.js. All of the modals, menu, and dialog windows are custom. All of the CSS is custom. Trello uses and icon font for icons.
