I have a specific need for a tailored appliance version of what you are proposing. It is the bootable client appliance remote-desktop front-end for an end-user F95-based modeling language <http://www.metacalculus.com/lens/Spiritext.html> surrounded by xterm menu scaffolding <http://www.metacalculus.com/lens/MIDUS.html> in Perl. The remote desktop server is configured as a TDE R14 Ubuntu 14.04 Togglebox VPS now. It is part of the scaffolding for an end-user development (EUD) type of workflow called quality assurance and evolution (QAE) to extend a science exploration modeling technology called MetaCalculus <http://www.metacalculus.com>, which has been under continuous development for 50 years. End users can connect to this remote middleware via NX remote desktops <https://en.wikipedia.org/wiki/NX_technology> from the bootable appliances, similarly configured as TDE-Ubuntu or TDE-PCLinux <http://trinity.mypclinuxos.com/> distros on LiveCD or LIVE USB sticks. NX remote desktops communicate through FreeNX server apps, and NoMachine <https://en.wikipedia.org/wiki/NoMachine>, Remmina <https://en.wikipedia.org/wiki/Remmina> or X2GO <https://en.wikipedia.org/wiki/X2Go> client apps. The front-end PC and Togglebox TDE desktops are preconfigured mirrors that merge with each other, each having 20 virtual desktops accessed though side panel pagers (client-right opposing server-left). Taskbar panels similarly oppose each other (client-top opposing server-bottom). This is the front-end of a server-based MetaCalculus "automation lab" (AutoLab). This dual mirrored OS client-server "AutoLab ensemble desktop environment <http://www.metacalculus.com/doc/MIDUS/AutoLab_Desktops.html>" is designed for shared menu-guided workflow of an EUD-QAE team on a collection of virtual desktops, some on client and some on server via several connected interactive sessions spanning multiple servers, where up to 400 (20 x 20) sessions may be running simultaneously from a single PC workstation. And since NX supports desktop sharing, the desktop collection can span teams of overlapping user workflow sharing of teachers and students. As you can imagine, this dual OS Infrastructure as a Service (IaaS) ensemble is designed as an integrated front and middleware interactive workflow environment, which in turn fronts a background massively parallel Docker batch system for cloud supercomputing, using AWS et al <http://www.metacalculus.com/AutoKey/Linux_VAR_Wholesale_AutoLabs.png>. It can integrate "super SaaS" collaborative open-source development and K-12 end-user STEM education <http://www.metacalculus.com/AutoKey/Retail_Linux_USB_Appliances.png>. The modeling language, an F95 Extension "NeoFortran" supporting the modeling solver and kernel API of the original mainframe PROSE language <http://www.metacalculus.com/doc/imgzoom/HolonModelingInPROSE2.png>, can operate on all three of these computing layers (client PC, Togglebox VPS, or AWS et al) in various configurations (from client tablets for K-12 students to Togglebox VPS's for developers to AWS Docker jobs for high-fidelity big-data simulation models globally optimized in massive parallel jobs). Since the NeoFortran is an optimization modeling language <http://www.metacalculus.com/doc/FC/Synthetic_Calculus.pdf> which can optimize system-dynamics models <https://www.google.com/search?q=System+Dynamics+Images&espv=2&tbm=isch&tbo=…> translated via the XMILE protocol <http://www.metacalculus.com/AutoKey/MCSD/XMILE_Example.png>; and since optimization searching is embarrassingly parallel <http://www.metacalculus.com/doc/DigiCal/MOBHeraJupiter.html>, this integrated environment can support interactive SERIAL modeling of parallel optimization processing <https://docs.google.com/spreadsheets/d/1uLtZUZybn3uxYIxrmB5If8bNmWxM_ZASbfP…> in the cloud (similar to web searches), *without any parallel programming*. Simplification of this parallel processing is what I am working on now. Although I am a Trinity user, and have been since the fatal KDE4 fork that set back my downstream development by several years, I don't participate in this forum much, but I would like to see Trinity win the desktop race. As you can probably tell, most of the higher infrastructure I have shown in the links above was accomplished before that plasmoid fork. Ironically KDE (as one of the original two Linux desktop environments) is still more generally sanctioned than TDE. But the general trend (Windows style war) that forking trend was part of has hobbled the whole Linux community in another pursuit of the Tower of Babel. I would like to see the Trinity community adopt this LiveCD/USBstick Linux-boot ensemble as a QAE project and expand its desktop functionality. There are many TDE improvements I can think of that this QAE effort would mandate. Not the least would be integrated QA with the NX clients, which would significantly improve overall Linux interface reliability. This effort would enable TDE to trump the KDE style leadership with EUD-friendly practicality. The intent is to adapt more of an EUD "walled garden" approach, like Apple has achieved with the Mac, in order to broaden Linux EUD. In the above links you see evidence of a host of integrated EUD automation apps designed to lift the OS development focus out of the "Windows style swamp" that the Linux downstream community has blundered into. My intent is to emerge new EUD order out of this chaos by giving* the original computing language new life in the clouds: optimization of simulation modeling in parallel processing, without parallel programming*. This can be the killer app to transform the industry the way Fortran did originally, by exploding diversity in R&D; something IT middlemen cannot accomplish on their own, because they are not diversified enough to match the diversity of science, like end-users are. Thus we need to simplify and generalize advanced Linux EUD as this ensemble aims to do.

Upgrade of TDE DVD 14.04 to 16.04 -- FAIL
by Jonesy 01 Aug '16

01 Aug '16

I've just installed the Trinity LiveCD tde-ubuntu-14.04-desktop-r14.0.3-amd64.iso and performed all the updates. I commented out the entries in /etc/apt/sources.list.d/libreoffice-trinity.list -and- /etc/apt/sources.list.d/trinity.list and did a sudo do-release-upgrade to upgrade to xenial (16.04) and received the following: |Checking package manager |Reading package lists... Done |Building dependency tree |Reading state information... Done |Building data structures... Done | |Calculating the changes| | |Calculating the changes | |Could not calculate the upgrade | |An unresolvable problem occurred while calculating the upgrade. | |This can be caused by: |* Upgrading to a pre-release version of Ubuntu |* Running the current pre-release version of Ubuntu |* Unofficial software packages not provided by Ubuntu | |If none of this applies, then please report this bug using the |command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. | |Restoring original system state | |Aborting I don't see how any of the "This can be caused by" pertain.

There is some forecast of getting rid of autotools?
by Anderson Torres 31 Jul '16

31 Jul '16

Hello, guys! I want to know if there is some forecast on getting rid of autotools and using only cmake, mainly because I want to port trinity to NixOS, and it would be easier taht way. Thanks in advance! Torres

enigmail (GPG) with kmail-trinity
by andre_debian＠numericable.fr 30 Jul '16

30 Jul '16

Does anyone has succeeded to install "enigmail" with kmail-trinity, or an application similar to enigmail ? The objective is to use GPG keys in kmail-trinity. enigmail works with thunderbird, icedove (Debian), but not sure with kmail-trinity. Have a nice day. André

And what about installing the Ubuntu 14.04 Trinity live CD first and then apt-get dist-upgrade? This would upgrade Ubuntu to 16.04 with minimal risk. I did this to go from 12.04 to 14.04 without any glitch. Just a hint from my own (successful) experience.

Re: "Could not find mime type application/octet-stream"
by Pavle 30 Jul '16

30 Jul '16

Hi, I use Trinity on Arch Linux. I didn't use a display manager, but rather started Trinity and I3 through .xinitrc script (I don't know if it is relevant). After installing Trinity, some of GTK apps (Midori, dwb) failed to start in I3, with similar message: "Could not find mime type application/octet-stream" and segfaut. Didn't test in Trinity. First quick fix was to set an environment variable GSETTINGS_SCHEMA_DIR=/usr/share/glib-2.0/schemas but some other apps (SpaceFM) still segfaulted after many error messages. Then I disabled /etc/profile.d/trinity.sh and started it only when starting Trinity, which solved my problem.

LiveCD for Ubuntu 16.04 LTS
by Marvin Jones 29 Jul '16

29 Jul '16

I am building a new workstation and I really, Really, REALLY want to fire it up with Ubuntu 16.04 LTS with Trinity R14.0.3. Ref: https://wiki.trinitydesktop.org/LiveCDs , has anyone built a Live CD for Xenial yet? Or, is a Live CD under construction? Or, has anyone installed installed TDE 14.0.3 on Ubuntu 16.04 yet and could/would share their experiences if I run into "challenges" during a raw install? I don't believe I've seen any chatter about Ubuntu 16.04 on this list. And, I really do not want to start out 2-years old with Ubuntu 14.04. "Inertia" usually prevents me from upgrading releases once I have a solid linux workstaion humming along. Hell, my primary workstation is $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04.4 LTS" ... with TDE 3.5.13.3 Thanks for reading this, and thanks for TDE!!

"Could not find mime type application/octet-stream"
by Curt Howland 27 Jul '16

27 Jul '16

Hi. I seem to have messed up the file associations list. I went into Trinity Control Center to add .webm as a video file type, and somehow deleted something so that now I'm getting "Could not find mime type application/octet-stream" errors every time I drop a file onto the desktop. Maybe I could recreate the entry, or copy the default file associations list back over my user .trinity list? I don't want to have to reinstall everything just to clear a "Sorry" pop-up.

Ktorrent not showing peers' Country
by Dan Youngquist 26 Jul '16

26 Jul '16

Ktorrent's Country column isn't working, it just shows N/A for every peer. Any ideas why? This is a Debian Jessie system with TDE 14.0.4 from Slavek's repo, updated this morning. Thanks. -- PGP key: http://homestead-products.com/pubkey.htm
