How to increase the UI font size in SQL Developer Data Modeler 18.2?

I am using Data Modeler 18.2 and I want to increase the font size of the Interface, but I cannot find a way to do it. I managed to do in the main sqldeveloper, but even though I've searched through many folders and config files, in data modeler I cannot find a way. I'd appreciate it if someone knows the trick!

ArangoDB Graph Viewer Options: Label using more than one attribute

In Arango's Game of Thrones example dataset, they show a graph view where character nodes are labeled with two attributes: name and surname. How is this done?
Arango graph viewer example with Game of Thrones character data
The help doesn't explain it.
Graph Viewer Options
Nodes Options Menu:
Label (string): Nodes will be
labeled by this attribute. If node attribute is not found, no label will be displayed.
That makes it sound like only a single attribute can be used, yet their example shows the use of two attributes.
Luckily it's ArangoDB open source, so it's possible to achieve it and quite easily
here's quick and dirty commit adding such a functionality
to test it, not deploying it into production as it can cause unexpected security issues
clone on linux https://github.com/pavelsevcik/arangodb, cd into it, switch branch to feature/graph-viewer-config-labels--quick-and-dirty and run
cd js/apps/system/_admin/aardvark/APP
npm install
npm run grunt
mv node_modules ..
zip -r ../app.zip .
mv .. /node_modules .
then deploy created js/apps/system/_admin/aardvark/app.zip via services > add service > upload > set mount point to /aardvark
then change in url _admin/aardvark to aardvark and test it
here's Feature Request: Support of multiple attributes for displaying labels in Graph Viewer
The Graph Viewer does not support multiple attributes for displaying labels.
I took a screenshot of the graph without any labels and edited it in Paint.NET, that's the whole secret. This was for full control about the font face, size and placement. This combination was the easiest way to do it when I wrote the AQL tutorial.
Feel free to open a feature request on GitHub nonetheless.

publish or export a ADF task flow diagram to external document -- possibly in PDF format

JDeveloper 12c permits viewing ADF task flows as diagram. Is it possible to export the diagram part to an external file--pdf or png?
If you have Windows 10, you can probably use the Print Functionality.
From File Menu > Print (or Print Preview) and Select "Microsoft Print to PDF", attached screenshot displayed below:

FBX import crashing UE4

Exporting from Maya to UE4 is causing the UE Editor to crash with no explanation. The submit error report dialog appears but there is no useful information available.
I have tried changing the FBX Version as some posts suggest, however, this does not seem to help.
How can I go about addressing this issue?
When exporting make sure the base model is in editable mesh and not editable poly and make sure the FBX exporter is set to ASCII not Binary.
This happened to me on 3ds Max, I am not a maya user
i had recently come across with the same crash... while importing from fbx
from mixamo and maya what worked for me was....while exporting fbx i had done the resetting of fbx preset to autodesk media and entertainment and switched off the smoothmesh option and enabled the Triangulate..
please do delete the unused nodes before exporting and keep no group nodes above the mesh or skeleton...
hope that helps those encounter similar in their workflow
as i was doing the following test projects this error occurred and crashed...

Drupal working with external db

Hi i want to build up a site which is connected to external db.
This data store around 10000 products (ex. toys and each toy have few attributes). I am able to implement it to module how ever what would be the best direction to go ?
My thought was to build custom node module which will create node for each position but this give me plant of nodes. ( I never had chance to deal with bigger db)
What would be better solution?
Thanks for all ideas.
Your choice is to use Migrate module. With this module you can extend the custom module, to convert all the 10,000 Data in to nodes in Drupal system.
Trust me Migrate can handle more than 10,000 data. Actually it is not a Bigger DB.
