Tethering fees are another "brilliant" invention by the customer-hating American telcos. You get a set amount of data per month, for instance 20GB. Why should they care at all what you decide to use that data for?

I thought that tethering fees only applied to unlimited plans now? At least with Verizon, there is no such fee for the normal data-capped plans.

I have unlimited data with T-Mobile and no tethering fee.

What I would like to do is use my phone as portable storage device and then plug it in to external processing unit and boot from my phone. The external processing unit could be desktop computer, laptop or tablet. The reason? When sitting behind my desk at home or office I don't like to be limited with the mobile CPU. I have the required kWhs to power a proper CPU, GPU and run 64GB of memory. I also don't want to run…

We really need robust USBC drivers. Even Apple, being in the forefront of USB C connectivity, is vastly lacking in robust USB C operations. Plug in/out of usbc cables causes dramatically high crash rate on the new MBPs

Ah so I am not the only one! My MacBook Pro was regularly crashing completely when I unplugged my dock while it was closed. I now always have to wake up my MacBook before I unplug the dock.

I think you're thinking about the EOMA project. Boards are soon to go out for their production run. https://www.crowdsupply.com/eoma68/micro-desktop/updates/pcb...

Yes that is indeed what I was thinking of - it's a very interesting project. Imagine if that device was a fully functional, standalone phone ...

I don’t understand the desire for this. In this model, you’re still carrying a laptop. It’s just utterly useless without the phone.

Just bought a Dex Station. If Emacs runs well enough then it will be a lifesaver.

If Emacs is all you need, you can run it today with Termux. Dex is of course nice for giving a bigger screen etc. What this "Linux on Galaxy" thing will provide on top of Termux is X (or Wayland?) and probably a bigger selection of software.

I already tried Emacs in Termux but I was too slow and did crash while trying to do some things.

Nowadays I simply use JuiceSSH and mosh to connect to my main computer. I would like to have Emacs in my smartphone even while I don't have mobile signal though.

> I don't want to do a full reboot every time I "unplug" the phone from desktop processing unit and move it somewhere else. How do you expect this to work? You can’t hibernate an OS and swap out all the hardware and expect it to actually wake back up. You’re going to have to do a full boot.

That's true, but we're getting close: Linux ostensibly supports power-toggling and hot plugging CPUs, memory, and disks at this point. I think it's more focused on allowing VMs to be resized and replacing bad components in servers, but I know that some systems are already using some of this tech to improve power management and support better hibernation. I think there's still quite a ways to go to make graphical sessions robust enough to be suspended and then brought up on different hardware (I don't think things are presently set up to allow for changes to the pci controller and X sessions expect things to be pretty static, as evidenced by the hoops you need to jump through for switchable graphics), but we may get there if a major company ever decides to take an interest.

Maybe I'm the only one that is getting tired of smart phones? I feel like it just takes over every ones life sometimes. I'm ready to go back to a $30 nokia that just f'n works for half a decade, doesn't die every day due to battery usage, and in general... doesn't spy on my entire life story for the supposed purpose of better targeted ads.

I think there's some serious room back in the mobile market with the way these devices are going. Outrageously expensive disposables aren't sustainable forever. At some point people get tired of throwing $500 in the bin for the exact same thing they had last year, just so they can have a full day worth of battery charge again.

would love to do that, too - but if you use the phone responsibly and maturely then its smartphone capabilities are pretty useful.

for starters - don't throw away the phone - throw away the crapps - FB, WA, IG, Twitter, SC, ...

Actually, you probably could. If you write the hibernate image to a place using a machine-id of some sort. Imagine you have images like

    /hibernate/machine/5c76f5e0-9117-4e33-8093-9de2e2f1b6de
    /hibernate/machine/d755fe2c-2b13-4436-8a5b-ba3363b9c642
When your kernel boots up, it grabs its machine-id and looks for a hibernation image to map into its memory. If it finds one, great, you have an "instant wake". If it doesn't, you boot as normal. Now imagine that your kernel tries to mount a specific device to `/hibernate` prior to looking for hibernate images. Upon hibernating, it writes its image to its machine-id. You could easily share the disk between two machines (even of different architectures) and keep two separate hiberante images on disk. You wouldn't be sharing the processes, but you could share your data.

With a sophisticated enough setup, you could probably even dual-install binaries (although this would be much involved with ELF where you must have separate binaries compared to something like Mach-O) to something like /usr/bin_x86_64/ and /usr/bin_arm64/ and then use your shell to select your path. This might work on a system level, but would certainly work on a per-install basis manually.

One solution is use rdnis over usb.

It allows ethernet connection over USB.

Once ip network is setup, you can easily run nfs, samba, vnc over that network interface.

A few years back when I worked on AOSP project, I dislike the tools from Android. I put a "ubuntu for arm" rootfs in a subdirectory inside a cell phone platform, chroot to that subdir. I have full ubuntu environment inside a cell phone. xfce4-terminal, ddd, nfs, samba - ~40k ubuntu packages all available with a simple apt-get install command.

As long as you have enough RAM, CPU cores, storage space inside a cell phone, it is very easily to setup.

If you keep the vnc server running, you can plug and unplug that cell phone to any desktops, thin client and your can instantly log back into the same GUI environment.
