Re: [Android] Running debian + emacs on my Android G1 [was: [Orgmode] emacs + orgmode on Ubuntu on Android G1]

The way I installed debian caused the swapping via "compcache" to be disabled, which I remedied by now (see wiki page above). That helps with some problems with memory consumption, but doesn't really make things faster (I have a slow SD card, I think I will order a faster one soon). I didn't manage to get below 9 seconds for changing from one day to the next in the agenda, even though I moved out most of my reference material (and that way I have a more pure GTD-setup in my org-files now). > Thus I'll only be using the local emacs on my android phone as a > fallback when I have no (fast) network access, otherwise I'll use it > via ssh on a much faster host.

I have a remote host on which I use emacs + org mostly from the phone, so I have my @G1 and @Network context on that box and use speed commands, fast tag selection and context based auto exclusion to get the right context. So if I have to wait for a delayed train again, I can just pull up my shopping lists ;) The debian installation remains on my sd card, since it's nice to have the familiar tools with me in a pinch. I guess android based smartphones will be much faster a few years from now, if they still exist, and then maybe this setup will be more frequently used. -- Friedrich Delgado Friedrichs TauPan on Ircnet and Freenode ;) pgpf5Wxpb1YNW.pgp Description: PGP signature ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

Re: [Android] Running debian + emacs on my Android G1 [was: [Orgmode] emacs + orgmode on Ubuntu on Android G1]
Ok, summary of my experiences so far: Emacs runs nicely, but uses a lot of memory with org mode, and it's hard to use the agenda and probably difficult to make it run much faster. Thus I'll only be using the local emacs on my android phone as a fallback when I have no (fast) network access, otherwise I'll use it via ssh on a much faster host. > As using this via the small keyboard is still awkward, even with speed > keys (let's face it: emacs just wasn't made for small keyboards), and > because it's still going to be slow, even if I can optimize it a bit, > I guess I'll still be going forward with my plans for integrating > org-mode with Remember The Milk. As a sideeffect of this experiment, I have my org mode set up in a way that is much more convenient to use on a small keyboard, that way I can use it via ssh (connectbot) quite comfortably now.

Re: [Android] Running debian + emacs on my Android G1 [was: [Orgmode] emacs + orgmode on Ubuntu on Android G1]
A small update, I'll probably continue next weekend: > I have emacs + org-mode running now, but it's very slow. Emacs on > its own runs and starts quite fast, but as soon as I add my whole > config, it takes 90 seconds to start, and 30 seconds to change in the > org-mode agenda from one day to another. I've put some 'if's around the parts of my emacs config that I don't need on my phone, and I also cut down on the org files (no Someday/Maybe stuff on the phone, it's not relevant for the agenda anyways... hm, I could actually leave those out of my agenda everywhere). I got down to 9 seconds for changing to the next day, and 20 seconds for changing to the next week. (Emacs startup time stays at a constant 90 seconds, even though I've cut out many elisp files.) I think if I separate my Notes (i.e. pure reference Material) into separate files, I'm going to make it under 5 seconds. In an old thread I read Carsten talking about implementing some kind of cacheing mechanism for the agenda, I think at this point I'd be interested in something like that ;) Memory usage while using org + emacs is ok, I can even leave emacs running in the background. If it's idle, I won't even notice it's still running (Yay for Apps2SD, it really frees up the main memory of the phone). As using this via the small keyboard is still awkward, even with speed keys (let's face it: emacs just wasn't made for small keyboards), and because it's still going to be slow, even if I can optimize it a bit, I guess I'll still be going forward with my plans for integrating org-mode with Remember The Milk. But now I'm really tempted to start using mutt as a mail client on the phone ;) Have a good week!

A small update, I'm not done yet: I have emacs + org-mode running now, but it's very slow. Emacs on its own runs and starts quite fast, but as soon as I add my whole config, it takes 90 seconds to start, and 30 seconds to change in the org-mode agenda from one day to another. As 30 seconds are way too long, I'm obviously going to try cut down my config and maybe just use a subset of my org-files on the phone. If I can't that last figure below 5 seconds I think the experiment is going to be called off as a failure. (Or maybe I'll just use the local emacs as an emergency fallback if I have no network access.) Apparently some system administration tasks on the debian installation take so much memory that the whole system gets unstable, because the oom killer is going to kill important services. I just had to reboot my phone after generating a UTF8 locale. I looked at adb logcat and the android core was very unhappy and killed every service it could find, even the phone service... So I probably want to make sure I don't need to use my phone when administrating the debian installation. > > I didn't run emacs yet, but I have a suspicion that it might run a > > little faster on a native ext3 partition than from an image file. > What do you mean by an image file - does yours involve some kind of > loopback?

The debian installer uses a loopback mount, as it doesn't require a native ext filesystem. This is probably handy, but I guess most root mods these days use an ext partition anyway, so why not just use that...
