comment Multiple GUI windows in one (GUI applications windows multiplexer/wrapper)
Thanks for the comment @goldilocks - problem with tiling window managers like awesome is that they change the entire desktop environment paradigm (vs. what I'm used to); I'd basically like a tiling window manager only inside a scalable (floating) window with a titlebar, which I can move around - while it keeps the positions of the inner applications in sync; added clarification to OP. Thanks again - cheers!

comment Repeating a text-output terminal command, in a scrollable ncurses-like interface?
PSS: Multitail linked from one of the pages on this answer also looks neat, but it needs to be built from source (for me, libncursesw5-dev was also needed); but unfortunately it can scroll "only the last 100 lines", and refresh of the command kills the scroll window (as of v6.0).

PS: pwatch seems to be able to do what I wanted; except it needs handlers for proper termination of ncurses; it also (currently) terminates prematurely if one goes above a certain line in the ps axf output (though scrolling works). But otherwise, that was what I was looking for. Cheers!

comment Repeating a text-output terminal command, in a scrollable ncurses-like interface?
Many thanks for that answer @slm - it explains well that what is a "state of the art" for this problem (which I wasn't aware of) - so I accepted it for now. I got both atop and htop - and it seems, none of them report kthreadd and its "dependencies"; and that is a part of what I need this for (and which is why I wanted a "generic" application which gives one a curses scrolling window). Thanks again - cheers!

Thanks, @MarkPlotnick and @Marki - unfortunately, there seems to be no scrolling behavior with watch, although, at least it keeps the start of output on top of terminal...

comment Linux Kernel logical address space organisation
Thanks for the example! Just my note on the Linux part - I just tried this example as where.c, on Ubuntu 11.04 using gcc where.c -o where; reports "main at 0x80483c4". Tried readelf -S where, and it reports, say "[13] .text PROGBITS 08048310 ... " which looks about right? Although I also get "ac at 0xbfb035a0" and "local at 0xbfb0358c", and that address range (0xbf...) seems not to reported by readelf -S.

comment Resolving executable user stack trace addresses in ftrace
Thanks for the edits, @slm - I definitely do not have -dbg packages loaded; which is why I find this strange - if they were the problem, then I shouldn't get any resolved traces from Xorg or other processes? And this trace only gives an offset into an executable file, so the debug info (as in, a link to source code file and line number) isn't even needed... Yet, I get stacktraces resolved everywhere, except my program; and the program isn't even linked to anything other than (implicitly) libc?

comment Resolving executable user stack trace addresses in ftrace
Many thanks for the answer, @slm - could this also refer to the libc library? As I don't see what other library would the program above refer to... Cheers!

comment Observing a hard-disk write in kernel space (with drivers/modules)
A small note: some of the explanation in this answer (e.g. dirty pages flushing) is observable, if in the sudo bash... script in the OP: ftrace memory is increased (echo 8192 > $KDBGPATH/buffer_size_kb); and sync ; is added after the ./wtest ; call. Then I can see flush-8, kworker (under kthreadd in ps axf), and sync itself, as processes in ftrace calling functions like e.g. ata_bmdma_setup() (which is part of libata, which ata_piix builds on), or get_nr_dirty_inodes().
