Ubuntu Touch OTA-12 Update

I installed the new update of the Ubuntu Touch today. Only on my tablet at the moment. There are some impressions:

  • External keyboard support is improved: easy switching by Win+Space, AltGr support, works well in X11/Xorg applications, too. No external keyboard layout indication is available, though.
  • Xorg support improved. I am now able to compile and run my own X11 programs. The whole thing seems to be more stable, too. There still is no working clipboard support between X11 and native applications.

The TeX works (the TeXlive can be installed), the gcc works and the GNU Octave works.. Well, the ParaView is even not available for install.

Freshly compiled uFEM on Ubuntu Touch

There are still many rough edges (for example the way how multiple windows in Xorg emulaton works – you have to switch them by clicking o a small symbol in an ugly titlebar) but at the moment I am able to use it as a notebook replacement (the only really missign thing is a support of external VGA screens: the 1920×1020 or so is not an option for the most of dataprojectors around).

Of course, lot of things is impractical and not very configurable due to the limitations of the mobile operating system.

Ubuntu Touch OTA-12 Update

No shocking news

I use non-SGI computers more and more (both my phone and my tablet are Ubuntu Touch based and my 2nd desktop is the Intel Compute Stick with the Ubuntu) but I still use my O2 most time.

Work (sort of)

The O2 has a bunch of programs on all virtual desktops (some manuals, text editors JabRef and so). There are visible only some terminals (RXVT ones) which are connected to remote machines (they are much faster than my O2 so I use them for actual number crunching). The Vim and the Gnuplot are of course running locally…

Chip(s) for your pocket

Well, no potato products will be discussed here. But there is something interesting: a pocket verision of the posibly world-cheapest ($9) computer – the C.H.I.P.. Yes, I have got the Pocket C.H.I.P. thingy.

It cost me more than the advertised $49, of course. I live in an expensive country and the shipping was also not free. By it’s still quite cheap.

After some limited success with the bare C.H.I.P computer (which is less or more equivalent to the original Raspberry Pi) I decided to try the pocket version.

By the way: my main trouble with the C.H.I.P itself was the video output: only a TV-grade output was available at the beginning and I don’t have a proper TV. The rest was OK, except the speed with the default XFce desktop (the thing has a 1 GHz ARM processor but only some 512 MB of RAM).

But back to the main topic: the Pocket C.H.I.P. look a bit cheap (but it has to look cheap because it is..) and the keyboard is a bit strange but it is functional and easy to use. It is relatively big. So it is large for a pocket but big enough to be comfortable bot for reading and for typing. The screen resolution is 480×244 which is unusual and very low for today’s standards but optimal for an indented use. By the way, using RXVT means that you have perfectly readable text which is pleasant for your eyes. And the DOOM is also not that bad here…

MicroDef on PocketC.H.I.P. computer

I must confess that I got the thing with no particular reason of plan for an use. I was just curious for what the thing can be usefull. At the moment I thing that it is not so bad as portable calculator (Octave + Gnuplot) and I even managed it to compile and run my MicroDef. Fortunately, I have modified the MicroDef for very small screens in the past (for my Ben NanoNote computer) so the use on an another small device required no code changes.

The OS of this thing is a normal Debian (armhf) with the X11 (no Mir, no Wayland, no other mess is here) so things are very simple here (there is a custom launcher and a simple setup tool but the rest is stock Debian). One can install almost anything here if the software fits in it’s 4 GB flash space (there is no expansion port) and if the software can work of its low-resolution screen.

At the moment, I can confirm that lot of stuff actually works on the computer: gcc, GNU Octave, Gnuplot, TeX (latex at least), Vim, RXVT, Calc (apcalc),…
