#StackBounty: #gnome-shell #18.10 #workspaces Sometimes, I can't drag and drop windows into other workspaces

Bounty: 50

Sometimes, I can’t drag and drop windows to other workspaces.

It always works when I just boot up my computer. After a while (most often days), it just stops working. I can’t drag and drop anymore. I have to reboot to make it work again.

I’m on Ubuntu 18.10 with GNOME Shell 3.30.2, but I remember having this problem with Ubuntu 18.04 too.

Here is a video that shows the problem: https://youtu.be/s1shbBFvt3o

#StackBounty: #mathematical-statistics #likelihood-principle Did Deborah Mayo refute Birnbaum's proof of the likelihood principle?

Bounty: 100

This is somewhat related to my previous question here: An example where the likelihood principle really matters?

Apparently, Deborah Mayo published a paper in Statistical Science refuting Birnbaum’s proof of the likelihood principle. Can anyone explain the main argument by Birnbaum and the counter-argument by Mayo? Is she right (logically)?

#StackBounty: #18.04 #encryption #ssd #dd #tpm DD a BitLocker/TPM encrypted drive

Bounty: 200

Is it possible to create a bit identical image of a Windows 10 SSD using an Ubuntu live cd/usb?

If I boot into the laptop with the live/cd/usb, I can’t see the drive using fdisk or gparted.

The laptop in question is a Dell Latitute 7490. The laptop has TPM enabled and the drive is encrypted using BitLocker. I have tried disabling BitLocker, but still can’t see the drive to DD it when using a live cd/usb.

#StackBounty: #autodesk-forge #autodesk-viewer #3dsmax 3ds Max BlendedBoxMap support for the Forge Vewer

Bounty: 50

We are really interested in adding BlendingBoxMaps to certain objects in our model (such as terrain and larger geometry to avoid obvious repeating in the texture).
However, all our test has failed as objects containing BlendedBoxMap (see image below) turns black after translated to SVF. Any guidance would be highly appreciated.

Update:
If the above doesn’t work. Is there any alternative to BlendedBoxMapping to achieve good looking textures for larger terrain? We are aware that baking the texture onto large mesh gives very blurry results as the SVF translation reduces all larger texture resolutions to 1024×1024 (which seems to be impossible to avoid) and stretches the 1024×1024 texture as much as needed to fit the large object.

#StackBounty: #tiff #image-viewer Looking for a raster viewer to display 16-bit tif rasters properly

Bounty: 50

Currently I use IrfanView to display and quickly delete cloudy satellite images (by pressing delete button). But, unfortunately, some 16-bit, 3-band images are not displayed properly as RGB.

I tried to use this software to solve my problem, but all of them do not display satellite images properly:

What software can I use to quickly display and quickly delete 16-bit, 3-band tiff images?

Here is the original tiff image (with LZW compression)

Here is how it should be displayed correctly (screenshot of ArcGIS Desktop with raster metadata):

Here is what I see with IrfanView (and other software):

#StackBounty: #7 #taxonomy-terms #i18n-l10n Translating a taxonomy term does not populate content into fields

Bounty: 100

When translating a node into another language it does the following:

  • automatically populates all fields with content from the source node on the edit form
  • ensures the two nodes are linked as translations
  • defaults to the second language (if only two enabled)

When you press ‘translate’ on a taxonomy term it loads a blank form (as if you are creating a new term).

How do I duplicate the behaviour of the node ‘translate’ link for taxonomy term ‘translate’ – to create the same one-click functionality?

#StackBounty: #load-balancing #google-cloud-platform #google-compute-engine GCE TCP Loadbalancer access from within region always route…

Bounty: 100

We’re running across three zones in GCE with a TCP Proxy loadbalancer in front. The backend for the loadbalancer is on a single node within one of the zones. Using the health check, the loadbalancer can determine where to send the traffic. This works as expected when traffic originates outside of Google. For outgoing traffic we use a NAT gateway and a route with a lower priority than the default Google route (800 instead of 1000) to actually route the traffic for 0.0.0.0/0 there.

However, when one of the backend servers that’s not in the same zone as the (active) backend for the TCP loadbalancer tries to access the external address, it will get a connection time out. The route does not seem to get used. If the request originates from the same zone as the active backend, it works. The nat gateway route does not seem to be used.

One solution would of course be to make sure that there’s an active backend in all zones, but we prefer not to do that. One thing we note is that when we get traffic from within the cluster through this external IP address, the client IP address in our logs seems to be the loadbalancer address itself. Any idea how to solve this otherwise? Is this expected behaviour or did we possibly misconfigure some route or firewall?

#StackBounty: #ssl #tomcat #redirect #apache2 #lets-encrypt modern installation of Tomcat with SSL on port 443

Bounty: 50

In the computer course I’m writing I’m using Tomcat for the server. (Students learn how to set up CentOS and everything from scratch. Currently the course has them using Tomcat running on port 8080.) I’m going back to write the section on security. I want students to learn to set up their web server to use SSL/TLS on port 443, with HTTP port 80 redirecting to HTTPS port 443. This should be a very basic, fundamental configuration, no?

The last time I did this myself was about 10 or 15 years ago, when I compiled Apache myself and put it in front of Tomcat using whatever connectors (I’ll have to go look at my configuration from back then), purchasing outrageously priced SSL certificates and installing them manually. How I’m sure things are greatly improved. Recently I’ve set up Apache (I didn’t have to compile it) hosting static pages directly, and using Let’s Encrypt (once I figured out what I should be doing) for SSL was a breeze. It’s working nicely. So I assume I’d want to use Let’s Encrypt in whatever solution I prescribe to the students.

So what is the best practice, straightforward, and simple setup for Tomcat with SSL on port 443 (preferably using Let’s Encrypt) with HTTP port 80 forwarding to HTTPS port 443? Do I still need to stick Apache (or Nginx?) in front of it? (The last I checked, letting Tomcat use lower port numbers was a pain, and nobody seemed to know an easy, straightforward way to do it.)
