Another related tool I found interesting: perf c2c

This will let us find the false sharing cost (cache contention etc).

I do something like

  find $PWD -type f -ls | awk '{gsub("/", ";", $11); print $11" "$7}' | flamegraph.pl --title "Disk usage" --countname "bytes" --nametype "file" --width 1900 --minwidth 0.05

I have been using Global for about 6 years now. Mostly I use it in emacs (though at times I use the CLI version).

I use it in Linux and Windows. I mostly work on C/C++ (Linux kernel, Windows drivers etc) and also have used it for few C# projects (via exuberant ctags backend).

One real advantage I get: I switch platforms between Linux and Windows (the place I work for has both). So I use emacs in both platforms and same gtags customization works out of box in both platforms. This relieves me in learning/using new editor/tagging system for each platform.

FWIW: my dot emacs https://github.com/surki/dotemacs/blob/master/init.org

What you describe is implemented in these libraries: libduma (http://duma.sourceforge.net/) and efence (http://linux.die.net/man/3/efence)

They also have buffer underflow protection (either overflow or underflow at a time).

But in 32 bit systems, for applications that heavily use memory, you may run out of address space

Doing it in C with mixed assembly

  {
    long len = 0;
    while (str && *str++)
    {
        len++;
    }
  
    return len;
  }
  
  
  void print(const char *str) 
  {
      int len = strlen(str);
  
      long ret;

                            "popl  %%ebx"
                            
                            "a" (SYS_write),
                              "S" ((long) stdout),
                              "c" ((long) str),
                              "d" ((long) len));

For moving or persisting X applications you would need something like http://en.wikipedia.org/wiki/Xmove

Probably you are using x selection buffer for copy/paste. But if you want to pick up stuff from X "clipboard" buffer, you would need xsel or something like that.

Wanderlust is quite usable now. I use it everyday(I have my gmail and exchange server(imap) accounts managed in it). You should give it another try sometime.

I use a similar setup with urxvt and stumpwm. In stumpwm I have

    ;; Launch emacs
    (defcommand emacs () ()
       (run-or-raise
        "urxvt -title emacs -e screen -U -dRR -S emacs -c ~/.screenrc.emacs"
      '(:title "emacs" :instance "urxvt" :class "URxvt")))

which will launch emacs (or raise it if it was already launched).

Some of the thing you might want to consider when doing "emacs -nw"

  - Make sure your TERM is exported appropriatly.
    Otherwise you may end up with less colors (M-x list-colors-display).
    Screen fiddles with TERM and emacs may end up supporting less colors.

  - Copy/Paste between regular X apps and the emacs will not work.
    You would need to use something like "xsel". See here [1]

  - Some of the keys may not work as expected. This will be 
    apparent especially when using orgmode. You may want to 
    remap them appropriately

And also I suggest you use Emacs + Wanderlust setup for email (and put it in a screen session as well).

I think "The Man from Earth" was also partially distributed through torrents. At least that's what the wikipedia claims - http://en.wikipedia.org/wiki/The_Man_from_Earth

I use something like this to watch the processes that are running or waiting for IO

  watch -n 1 ps -eo pid,ppid,wchan=WIDE-WCHAN-COLUMN,stat,command r

You probably want to use tsocks. It LD_PRELOADs the socket related functions and does the necessary work.

I starting using magit recently, but I am still to get used to it.

Here is a link discussing about git support in Emacs that I found useful:

http://alexott.net/en/writings/emacs-vcs/EmacsGit.html

How about doing something with imagemagick or mencoder? I think video encoding/decoding gives a nice balance between disk and cpu usage.

Well, the example(at least the first one) in that video is bit skewed. First, he runs gzip and then immediately runs 'parallel gzip' without dropping disk caches. So in the later case the bottleneck would be CPU rather than disk IO(everything read from disk cache in the RAM). IMO I expect for the work that is IO bound we won't see any significant improvement using parallel or anything similar.

I strongly recommend having a look at the Gnu Screen customization in Ubuntu Server.

I see, thanks for the update. It would have helped if the title was Fennec 2.0 Alpha, not just Fennec Alpha. I would give it a try sometime this weekend.

Am I missing something? I remember trying this on a Nokia N810 about 1.5 years back, was quite slow, I gave up.

Looks like they are still working on it.

autossh http://www.debianadmin.com/autossh-automatically-restart-ssh...

  > Not perfect, but I find it's more natural to write in org-mode 

Do you have any specifics on the problems you faced? I produced my master thesis entirely using orgmode without any problem. (defined custom latex class, with different kind of ToC etc, not that difficult)

Check EmacsWiki as well: http://www.emacswiki.org/emacs/ArtistMode

Especially integration with Ido mode.

Checkout hs-minor-mode as well. Great for sifting through code (or xml, html etc)

  Got a computer behind a firewall whose configuration 
  you don’t have access to? It’s pretty easy to get the 
  computer behind the firewall to poke out to another 
  server.

  (step 1, from the computer you wish to access)
  derwiki@firewalledcomputer:~$ ssh -R   localhost:2002:localhost:22 mypublicserver.com

  (step 2, from any computer than can access  
   mypublicserver.com)
  derwiki@mylaptopontheinternet:~$ ssh mypublicserver.com -p 2002
  (authenticate)
  derwiki@firewalledcomputer:~$

If you want to keep it running always, you may want to consider "autossh" (restarts ssh connections if they ever exit/disconnect)

OK, didn't see that one. But technically it should be possible to do that(i.e., pure web rendering through JS) for TS as well.

What I meant to ask was - how does it compare using VNC against RDP. Probably you have through and rejected RDP, so was curious to know the technical details. (xrdp for Linux exists as well)

That's pretty neat.

If you are going to support Windows, how does stackvm compare against "Terminal Services Web Access (TS Web Access)" [1]

I assume you are using git to manage your home directory. I use gibak[1] for the same(built on top of git). Out of curiosity, what is your setup like?

[1] http://eigenclass.org/hiki/gibak-backup-system-introduction

That's nice.

I use

  emacs -Q -f list-colors-display

to find out the color codes

For the people out there who live in Emacs - Give Emacs + Wanderlust a try. It has a nice imap implementation, you can prefetch the mail, work offline, have multiple imap accounts etc.

Previously I was using Mutt + offlineimap

If you are using Conkeror, you can use create a page mode, specific to a site - http://conkeror.org/WritingPageModes

Conkeror seems to have a reddit mode already in place, may be you can cook up a mode for HN - http://conkeror.org/PageModes

Shouldn't we s/microprocessor/microcontroller/g ?

It looks like these the are the chips we are talking about

I use wget for the same. I usually call it from gnu screen, to update the status line with the no. of unread mails

  unread="$(wget --secure-protocol=TLSv1 --timeout=3 -t 1 -q -O - \
  https://${gmail_login}:${gmail_password}@mail.google.com/mail/feed/atom |
  sed -n "s/<fullcount>\(.*\)<\/fullcount>/\1/p")"

  unread=${unread:-0}

  echo $unread

And also worth checking out http://groups.google.com/group/emacs-g-client?pli=1 if you are into emacs side of the things.
