Is there any solution/instalation/tutorial for Crystal Reports (without VS) to create offline QR Code in report. I've tried generating QR code using google API (successfully), but need a offline workaround. Open source would be nice but commercial solutions are also welcome.
Thanks in advance
At least one 3rd-party Crystal Reports UFL (User Function Library) among those listed here can generate QR Code images on the fly without a dependency on font or internet services.
In Crystal, you insert a dummy image with the desired size of the barcode.
You then right-click and select: Format Graphic...
and set the the Graphic Location expression to the QR Code function call.
On Preview/Refresh of the report, the image is generated on the fly to the hard drive and immediately replaces the original image.
This takes only a few milliseconds so you won't notice any slowdown.
I've been using the fabulous Bwip-js, a server solution under MIT license, for quite some years now. It provides qrcodes (and all other kind of 1D and 2D codes) as response to HTTP requests.
In Crystal Reports you can insert an image and set its source to the appropriate URL of bwip-js.
My instance is running on a lightweight Node.js server, needed only small changes in their node.js example script. It all works like a charm and very stable over months without reboot. Excellent project.

Do you know any good tools to support the translation of .arb files?
It's a standard for Flutter and since Google Translator Toolkit will be sunset soon (https://support.google.com/translatortoolkit/answer/9462068) we're searching for a good solution to translate/gather our translations
Edit (June 2020): There's great new open source project called Arbify. This is a self-hosted tool to manage multiple translation projects focused on Flutter. You can edit arb files and fetch them via Dart package tool.
Aside from that some services like POEditor have announced basic support for ARB too.
At the moment the best support for arb files is on Localizely. However, this is a paid service and has strict limits on a free version. It allows to export arb translation files with plurals and placeholder support. It doesn't support genders, though.
There is also one simple web editor and one desktop editor (Babel) that support arb files.
Crowdin supports .arb:
https://support.crowdin.com/supported-formats/
It is also able to pull the data from a Git repo and send Pull Requests on GitHub.
However, when I used it in 2018 there was a problem of ##last_modified attribute being updated without any other changes to the translation files, causing lots of churn in PRs. By that time, they were reluctant to improve the situation (based on email conversation with their support), so we resorted to manual edits.
https://localise.biz/ allows 2000 translations. Which I assume are 1000 strings in 2 languages or ~666 strings in 3 languages and so on. Which is more than https://localizely.com/ 150 strings

I am looking for a scala library that I could use to plot some interactive graphs that would produce e.g. and HTML file. I am thinking about 2D line and bar charts. By interactive I mean some basics like zoom and unselecting lines I don't want to see.
I found WISP which is very nice, but what I don't like is that I need a single output file with my graphs and don't want to start a server. (Basically, I could use WISP to get my graphs on a webpage, CURL it and save to disc and then stop my server, but this feels way too much)
Any suggestions?
How about http://lightning-viz.org/?
It supports Scala client. Sometimes, I use Jupyter notebook to talk to the lightning server to get interactive plotting. (or I can skip the notebook step, and get the interactive plots directly at the lightning server page)
http://lightning-viz.org/clients/#scala
It also supports a variety of interactive plots http://lightning-viz.org/visualizations/
I recommend using a data source (ie. sqlite if you don't want to run a service) with Tableau. Tableau is purely GUI based but it fits your use case. You can create dashboards and nothing beats Tableau for interactive data visualization.
They have a free version (with limitations) and free 1-year student licenses.

Is there any API Which can generate QR Code of any image when i will go to read it,it revels the same image.
Any suggestion would be helpful.
Thanks
There's no direct way to encode an image as QR Code. There are several problems to do this:
- Image would need to be encoded somehow and there's no standard to do that on QR Codes. So any implementation wouldn't work globally.
- An image usually contains hundreds or thousands of kB, while most mobile scanners struggle to decode a QR code with more than a few hundreds bytes (that's at least 1.000 times less information!).
To make it short: It's not possible to do that. Sorry.
A workaround is to upload an image to a server, get a link to that image and create a QR Code with that link. So when the QR Code is scanned, your image is shown on the browser.
QR Droid (for Android) implements this workaround. (QR Droid > Create > Local Image). But I don't think there's any API to do the whole process.
Create a Chrome Custom Search (go to chrome:settings -> manage custom search)
Then just create an entry:
QR Generator | qr | https://chart.googleapis.com/chart?cht=qr&chs=300x300&chld=H|0&chl=%s
then whenever you open a new tab or whatever, you just type qr space your url

Anyone know of a system or framework for a non-programmer form creation? Not a full implementation, but something that handles the designer aspect and something that handles the displaying for being filled in. All the logic we'll be doing. Maybe just a pair of widgets.
We've got a client-server application into which normal users enter and modify data in a thick client and we want to allow the customers to update and create forms with another thick client application, rather than calling us every time they need a letter changed. We want something to do the display bits while we implement the various hooks and functions the system uses.
We're a java shop, but we expect that we're open to writing these clients in another language if it'll be easier.
Possibly Xopus with a schema for the XForm could work.
http://xopus.com/
Try searching for XForms libraries and tools. XForms is a new-ish standard format for defining forms and there are some libraries and tools available for it. Haven't tried any of these myself.
EDIT:
This looks interesting: http://www.orbeon.com/forms/builder
Well, you're a Java shop so this might not be the best tool for you, but from you description you look like a classic case for Infopath:

What I want is lots of nodes which can expand making a mind map.
I'd ideally like to expand and collapse nodes. I would like to be able to navigate by either dragging around the page, or by following expanded nodes.
I have a colleague who needed that kind of functionalities to graph Maven dependencies between projects. He ended up using FreeMind to do the visualization. He just had to write an XML file conforming to the FreeMind format. I even think you can just use OPML as the file format and find a ready to use XSLT to transform it to the FreeMind format. Maybe FreeMind actually supports OPML directly (I havent used it for a long time).
Once you have your data in FreeMind, you can either export them, or use the FreeMind applet to display an interactive MindMap on your website.
Suggest mxGraph.
Suggest protovis, lovely javascript cross-platform visualisation library.
I think you are asking for a component that does what Visio can do, except that it can be displayed on a web page. Most likely you would have to create one from scratch, because mind mapping tools are always released as products per se and not customizable components. I suggest looking for a basic drawing/illustration component, and then putting your mind-mapping logic in it.
