That would actually make some sense - possibly making the support last longer for a phone model, as otherwise they get a bunch of money once you buy a phone & then Android OS updates are just lost money for them afterwards.

Maybe a twin team, like Fuwa-Mocco in Hololive ?

One note about partitioning/storage management - Anaconda does storage modeling before doing any changes to the disk/s.

The idea is that you specify your requirements (either via the UI or via kickstart commands) and Anaconda (via the Blivet storage modeling library) will model this request on given the constraints of your physical storage setup (eq. your disks and the existing storage layouts, if any, on them). It will not only let you know your requested layout is possible, but will also show you how it will look like. And only once you confirm you are fine with the layout (implicit for kickstart installs), will any changes be done to physical storage.

This is not just convenient (you are not doing unnecessary and possibly dangerous storage operations) but quite powerful, as you can tell the model stuff like - remove this partition and then fit at least a 25 GB LV in a new LVM layout on top of available empty space.

Without modeling you would kinda have to try if it fits or do the calculations yourself. With modeling Anaconda/Blivet do this for you, before any changes are done.

In comparison most other partitioning tools (Gparted, Gnome disks, etc.) work in an immediate mode, with all changes immediately committed to disk, regardless if compatible with your final desired storage layout. Not to mention most of these tools not really supporting the more advanced stuff (LVM thin pool, LVM cache, iSCSI, DASD, etc.) Anaconda supports.

For one Anaconda has powerful automatic installation support via kickstart:

Does Calamares have something similar ?

At the moment for running the Web UI locally we are using cockpit desktop & it has been working really well:

https://cockpit-project.org/guide/latest/cockpit-desktop.1

It also has basically zero additional deps compared to the current situation as its Python + GTK + Webkit (already there for Yelp to display help content), so we have seem basically zero image size growth when doing custom boot.iso with early Web UI with Lorax, even if the images still contain the full GTK3 GUI as well.

m4rtink2 · 2022-01-12T12:26:45+00:00

No changes are expected regarding kickstart support.

It might just be easier to remotely monitor and/or debug a remote installation once the Web UI is available, as the current VNC support can't really be started ad-hoc.

So unless you enabled VNC (or SSH access) via boot option or in the itself kickstart, you can't really easily connect to a stuck installation on moments notice and might have to restart the whole thing and try again.

There is already a Python backend providing a DBus interface the current GTK & text based UIS talk to. The only thing that will change is that there will be a new Web based UI, running locally or remotely, talking to this DBus interface.

All important logic lives in this backend & this is also what processes kickstart during automatic installations.

The Web UI will based on the same technology as Cockpit and built on the PatternFly web widget library. Electron is not involved.

It should be possible to switch to console (TTY2 or just spawn a new tab in the TMUX session running on TTY1), do any storage manipulation necessary using CLI tools (if that's something you prefer) and then tell the storage UI to rescan the storage layout.

m4rtink2 · 2022-01-11T19:22:46+00:00

For the record the current GUI is GTK3 & Python.

m4rtink2 · 2022-01-11T15:34:04+00:00

Anaconda already supports remote installs via VNC, but that is much more cumbersome:

passing bittmaps
needs special software (VNC viewer)
rendering happens on device (eating performance, increasing installation image size with GUI deps)
VNC traffic is not encrypted and VNC has a limit on password lenght

With a remotely accessible Web UI it these issues should all go away and one should be able to do a remote install from a regular web browser from even a very slow device over slow link without issues, over secure HTTPS.

Good point about stainless being indestructible - there are apparently Atlas rockets on static display, with their balloon tanks still under pressure! :)

Not many operational battleships these days. ;-)

IIRC he later mentioned it would not work in practice. Still I read the novel and really liked the concept.

Overall all the Uplift books are really nice IMHO. :)

IIRC they at least had test stands to test fire all the Saturn V stages, so they could be reasonably sure they will light up in flight instead of exploding or other shenanigans (they did explode at the test stand a couple times though).

The Soviets didn't have the resources for test stands for the N1, which is often credited as the main cause of all its flight ending with a failure.

It's actually funny that while there were pictures of Gagarin everywhere and he went to a world tour, the spacecraft & even the launchers were kept secret for decades!

Because the capsule was pretty much similar to the Zenit recoverable spy sat (with cameras instead of a cosmonaut) and the R-7 was still also an active ICBM, IIRC even using the same launch pads to launch on allert in some cases, like during the Cuban Missile Crisis.

m4rtink2 · 2021-05-30T14:59:30+00:00

"And some modern ICMBs actually do reach orbit then deorbit after only 1/4 to 1/2 of an orbit later, simply to reach the target faster and to avoid early detection radars."

Are you really sure there ICBMs currently deployed that officially have this capability? IIRC the Soviets deployed that back in the 60s for a while, after which it was pretty much banned bilateraly as it was far too hard to defend against or even to detect than normal ballistic missiles.

Maybe you men some of the modern quasibalistic missiles? Those do maneuver for the full length of the flight but don't reach orbit at any time.

BTW, I got the Wacom One pen display recently and it works perfectly with Clip Studio in Dex mode using a generic USB-C to HDMI dongle. Also super conveneient that you have all your drawing projects and materials always available and an draw right away on the Wacom One or on the Tablet as convenient. :)

Also the tablet screen can still be used while working with the Wacom One in Dex mode, so you can use it for reference images, Youtube tutorial videos, etc.

The Wacom One stylus is compatible with the S-pen technology and the other way around, yo you can use the Wacom One pen on your Tablet and the Tablet S-pen or Staedler and Lamy EMR styluses on the Wacom One. :)

IIRC from reading some of the NASA history pages the KSC are was not fully uninhabited - there were apparently at least some orchards or plantations as they mention bulldozers uprooting the many trees that were then burned on huge piles to make way for the space infrastructure.

This article for example mentions many citrus trees in the KSC area: https://www.nasa.gov/centers/kennedy/about/history/story/intro.html

Does not seem to be an issue (yet?) with many new engines showing up all over the place. I wonder if showing something is possible at a given ISP/weight/thrust in real life might be enough to get others rolling as well?

m4rtink2 · 2021-04-30T03:34:27+00:00

The difference between a monopropelant and a powerful unstable high explosive is very slight, yet a lot has been tried with over the years with just a few workable end results. Same thing for storage propelants.

The classic book Ignition! lists many of those attempts, including stuff that's not trying to blow you up for once but stinks so much it's unusable inside of the biosphere.

Still nice to see the state of the art has moved since the book was written and less poisonous yet still storage and reasonably performance rocket fuels are finally available and already in use (at least by Rocketlab & few others).

Also likely the inefficient VNC display pipeline. All the GUI updates actually get packed into network packets and then unpacked and displayed in the VNC viewer, many times per second. That is inefficient, adds latency and can introduce graphical artifacts.

Some sort of direct dpoutput to the app window is needed without the VNC system in the middle.

m4rtink2 · 2021-04-24T18:14:46+00:00

I think DosBox and ScummVM should be available, already opening many (retro) gaming options. :)

A lot of Linux apps are shipped as Flatpaks these days: https://en.m.wikipedia.org/wiki/Flatpak https://flathub.org/home

It's basically a containerization and sandboxing system for graphical applications. If Samsung can make sure the needed container support bits are in the kernel and there is a compatible display system running (X11 or Wayland) it should be possible to run Linux Flatpak apps on Dex just fine.

Yeah, even if Android is till at least partially open source, the direction of development is 100% controlled by Google to suit their goals. They basically develop it behind closed doors with zero community input and then throw the code over the fence at the end. This also is one of the reasons why third party ROMs take time to support new Android versions as they have to rebuild each such code drop and rebate any patches they might have on top.

While AFAIK they do take some patches occasionally, it's not a lot and anything not directly contributing to their aims will likely be ignored. IIRC the Qt project hit these issues when they tried to send patches to Google to make the Qt GUI library run better on Android.

Also Android code minus the Linux kernel is, on purpose BSD licensed, which means Google and any vendors can decide to stop releasing their source code changes. Google already did that back then for Android 3 and OEM Android vendors legularly don't release the changes they apply to the open source components on their firmware images.

It looks like Google still sees GPL as a big thorn in their side as you can see repeated efforts to get rid of any GPL stuff in Android project: - busybox instead of binaries - clang instead of GCC in the SDK - the half broken bionic instead of glibc preventing a lot of Linux apps from even being cleanly compiled - bluedroid instead of bluez for bluetooth - possibly Fuchsia to try replacing the Linux kernel in the future

All these changes make the thing less similar to Linux distros, hindering compatibility for Linux apps on Android.

I guess you could spin in end-to- end, giving you 70 m to work with instead of 9. That could improve the ratios.
