Add all NP users to forum, this way all staff who use DaDesktop can be alerted more easily to new features as they are announced on the forum.

Remote Replica is a very useful new feature designed to replicate, or clone your Fresh Start Desktop to another server often in a different geographical location. Any changes to your machine will be silently and automatically copied in the background to the replica without requiring any further user input. Thus the Remote Replica is always ready if you need it.

New Documentation explaining useful ways how this feature can be used is now available as below :-

https://www.dadesktop.com/doc/remote-replica-1

Please let us know in the comments how you find this feature.

The ability to make publically available course recordings should be available on DaDesktop. This was previously possibly, but no longer appears to be possible currently.

We need to make sure that permission is given for this by the trainer and with the consent of participants first.

Course Recordings should be available on the DaDesktop site https://www.dadesktop.com/videos-catalog

Explanation

For certain errors / warnings we should use more specific or different wording according to the user role type. Examples below but there may be others required:-

Error not relevant to user

Here the user is a participant, so doesnt know/care what a FreshStart is , and can't control a Fresh Start machine anyway1 So this error message to a participant is very confusing and not helpful.
fresh-start-error.png

An error is shown that is not an error

A trainer who had issues with cloning FS to Trainer Desktop, getting 403 errors as the trainer desktop already existed.

403-error-not-an-error.png

here it should really say error, it should just be an Informational alert warning that trainer Desktop already exists

Another message that should only be shown to certain user roles

course-outside-hours.png

Here the trainer was confused, thinking that this message was for him and that he was only going to have 5 minutes to work on his material. But this message should only be for Participants, not Trainers who have full time access when creating a FreshStart

We've recently introduced improvements so that if you need to resize your Fresh Start machines, you no longer need to make manual changes to extend the partition within the VM itself. This greatly simplifies the process and saves time.

This is the case for any standard NobleProg OS Templates, using either Windows or Linux. Custom templates may still need manual disk resizing which is detailed in the guide below.

An updated guide to resize Fresh Start desktops can be found here https://www.dadesktop.com/doc/resize-disk-of-fresh-start-desktop-in-course

We will be releasing daily billing on 9th of May! It means you will have real time access to your next bill amount and breakdown!

I'm very pleased to announce that we have released a Debian 11 (codenamed Bullseye) OS template for DaDesktop today.
This new template is being distributed to all DD nodes so will be available to every DaDesktop region shortly.

DaDesktop Templates
As a note we support Windows, Ubuntu, CentOS and Debian officially but we're happy to provide custom templates for other operating systems such as Fedora if required.

Please get in contact with us if you require assistance https://www.dadesktop.com/contact-us

When using DD nodes that use fully cloud based infrastructure such as AWS, we should add an option to :-

'Click to extend memory' link on DD to change the amount of memory allocated to this server to permit high DaDesktop memory usage for DD Desktops.

Depending on config this may be done 'on the fly' or may require a VM reboot.

If a participant have high latency, detect whether they are using VPN, and notify them and advise them to do something about it.

I recently provided some training on the DaDesktop platform to NobleProg staff to explain more about DD, and to provide a run through of how it works and a quick look at some of the newer features too.

The video can be found below:-

NB The video is just over 30mins long.

Topics Covered

Training courses

General layout of DaDesktop

DaDesktop For Work (DD4W) - Flexible Virtual desktop machines that can be spun up in seconds to work from.

FreshStart - What is the purpose of the FreshStart Machine?

Training Room

Recordings - Room recordings or Trainer Desktop Recordings

Snapshots

Remote Replica - Available for Standalone and dd4w machines, not for FreshStart nor course desktops currently

Chat

Multi-trainer capability - With example

Users in different geographical locations - For trainer, freshstart desktop and participants

Spool - Ability to keep course desktop after the course finishes

Port forwarding allows exposing a port or ports of a desktop to the local network or the internet. It is commonly used with Remote Desktop Protocol.

This feature can be used for both DaDesktop Course machines (Super admin and own permissions required), DaDesktop For Work or Standalone machines. Please note, the interface may appear slightly differently for the different types of machines.

This feature has been improved by the addition of auto allocation of ports both TCP and UDP as well the maintaining the manual port forwards feature as originally introduced.

For further details please see the DaDesktop Port Forward Documentation

Sometimes, we only find our about course issues using DaDesktop after the course is finished.

Although the Technical Support Chat icon is always shown on screen, it may be that users aren't aware that live technical help is close by.

A suggestion is to have the ability to send a helpful preset message (or newly written one even), that can be quickly and easily sent to all members of a course using the chat introducing the Tech support agent available at the beginning of the course in a semi automated manner.

This needs thinking through more for best effect but would be a big help I think ..

@tanvi

When we see 'Error 1006 in DD connection logs' this usually indicates an issue caused by the participants' network access, possibly restrictions on websockets.

For example something like Akamai CDN WAF could restrict access as it does packet inspection eg WebApplicationProtector-CS.pdf

"with Layer 3/Layer 4 Protections inspect packets and network connections to determine which requests to automatically block."

In this case there is little we can do so we should warn users with a message such as :-

'There is a problem with your network , please either change your network configuration or contact your network administration team for advice.'

Hi all

There's been a lot of improvements and new features added to DaDesktop recently so I thought it was a good time to update you with the latest goings on with DaDesktop.

New Forum : forum.dadesktop.com

png;base64d4c5f53bb7cfd370.png

Firstly, the new DaDesktop Forum, https://forum.dadesktop.com has been launched. The plan is that DaDesktop announcements, feature requests, bug fixes etc, will be presented and tracked in the open from now on.

The Tickets & Feature Requests category will include bug reports and new feature suggestions from Franchisees and the other users.

One example added this week, to give you an idea :- Accessibility - Pre Course readonly test should have audio test.

Franchisees will be able to login with their staff login as usual. Franchisees will also be subscribed to receive any new items added to the 'Announcements' category in the forum.
The forum is also open to course delegates and the public via their DaDesktop login.

The site has been recently redeveloped to improve the SEO of the forum content available.

Any feedback for the forum is welcomed.

New and Improved DaDesktop Features

Multi Trainers

A newly requested feature is the use of 'Multi Trainers'. This means that DaDesktop now allows one or more trainers on all its courses.
The trainers will each have their own login to DD, and can control the ‘Trainer Desktop’ as if it were their own.
The idea is that both trainers will be on the Audio conference, swapping over at intervals as appropriate, but can take control of the Trainer Desktop as required. This will be especially useful on longer courses, or courses that just work better with input from two experts in their field to the course participants.

vGPU - can now offer 3D graphics capability* on Windows and Linux machines on DaDesktop
A new Production DD node with this capability, hs2fi.npg.io has been set up, located in Europe.

This enables NobleProg to host courses for applications such as CAD packages such as SketchUp which were not previously possible because a full graphics stack could not be configured. This server allows SketchUp or other graphic applications to be used or installed.

Please get in touch for further info.

Removal of CentOS8 DD Templates, as this OS is now End of Life. A drop in replacement such as AlmaLinux or RockyLinux will be added in its place suitable for Redhat Linux RHEL clone OS course requirements.

Seafile - A new storage system, Seafile on the NobleProg network has been set up. This allows you to upload files, even full virtual machines from your own laptop or desktop that can now be easily accessed inside the Trainer's desktop machine.

Improved Clipboard - you might remember that we much improved the clipboard functionality at the end of last year. This has been since been further improved.
Although it may appear to be a small feature, the ability to simply copy and paste from a machine into the DD Desktop was one of our most requested features to improve upon. It's particularly useful on courses where delegates require a lot of copying and pasting commands etc as part of their course.

Likewise, ongoing updates are being made to the DaDesktop Documentation site to refine, update and improve the information held there.

There are many more smaller improvements coming through and also a number of wider improvements to the User Interface, some of which you may have seen already.
Full details of these will be posted on the next newsletter.

If you have any queries about any of these new features or the new Forum, please don't hesitate to get in touch with me.

Many thanks

CentOS 8 DaDesktop Templates have been removed due to a change in business model by CentOS.

A drop in replacement such as AlmaLinux or RockyLinux will be added in its place shortly, suitable for Redhat Linux RHEL clone course requirements.

Please note CentOS7 is still supported and will still be offered as a DD template.

A newly requested feature is the use of 'Multi-trainers'. DaDesktop can now allow one or more trainers for all its courses.

The trainers will each have their own login to DaDesktop, and can control the ‘Trainer Desktop’ as if it were their own.

Scenario - for a blind person, the audio part of the training is the only part of the learning, and ensuring that audio checks and course recordings are crucial. In this case, ensuring that testing the sound in DaDesktop before the course works as expected is of crucial importance.

As part of our existing read only test, eg Clock we should incorporate a simple Audio test.

This will help in two ways:

For participants who have normal sight and hearing but wish to check that their setup is correct. We do see a number of participants who cannot always hear the trainer at the beginning of the course. The audio is usually working fine, issue may be on participants side, but this does give the chance for users to test beforehand.

For participants with accessibility issues, the audio test needs to be slightly refined, as the user would not be able to see on the screen the button to press. Hence what is required is the ability to press a predefined key such as 'A' for audio which would provide a short 10-15 second sound sample .

If we start looking at accessibility of DaDesktop this is a vast area which may not be easy or quick to get optimised fully. However, thinking about users with different needs would be a good step forward and could lead to a project strand to develop accessibility at some point.

More control of the firewall, so as well as 'Enable/Disable internet access' an option for 'Enable/Disable local inbound access (excluding VNC from the gateway obviously!)'.

It was neat (and useful) that all our VMs were on the same virtual network - and indeed we made use of it in a couple of cases to transfer files, but I can also see cases where you might not want your colleague on the same course to get to ports on your VM - especially if there is some form of test / assessment involved. I guess in most Windows cases it doesn't matter as the Windows firewall will default to on, but still an option would be nice.

A user suggests:-

Some form of indicator to say the host has updated the fresh start image, to let the student know it's worth restoring. Maybe even a pop-up when they launch a session if there is a newer version?.

A new storage system, Seafile on the NobleProg network has been set up. This allows you to upload files, documents and even full virtual machines from your own laptop or desktop that can now be easily accessed inside the Trainer's desktop machine.

training-page008.png
The Seafile Docs server is accessible from anywhere, where you login via the SSO link and then upload course content etc, which can then be readily accessed within the DaDesktop Machines on a course. Trainers can use this feature to add content for a course. This tool can also be used to upload entire Virtual machines if they are to be used in a nested configuration using VirtualBox or Virt-Manager for example.

Alternatively, you may wish to use a cloud storage application such as DropBox, Google Drive etc, but this is likely to be slower in use within the DaDesktop machine compared to using the NobleProg Seafile cloud storage system.
