[Bug 597098] Re: jstack thread dump error: get_thread_regs failed for a lwp

[Andrew Ball]

For Tomcat, I was able to use kill -3 tomcat_pid as a workaround.  I
got basically the same behavior with OpenJDK on Ubuntu 10.10 x86_64.

Hello Alan,

  AP Ubuntu - it doesn't smell of death

I'd buy a (4XLT) tee shirt with that on it!  :-)

Re: [ubuntu-uk] Radio Software

[Andrew Ball]

Hello Chris,

  CW Our legal logger - this is simply a application that
 records an mp3 file from a live input creating a new
 file every 24 hours. Currently we use
 http://www.cooolsoft.com/mp3rec.htm but searching the
 linux-audio pages I'm unable to find a similar
 application.  Any ideas?

I would favour a modular approach: use some fairly
ordinary recording software to capture each programme as a
.wav file (I prefer .au, but .wav seems more common these
days) and then while the next programme is airing, the
previous can be compressed into MP3 and Ogg/Vorbis, perhaps
for posting on your Web site. This could be automated fairly
easily.

I'm assuming you want to do this for live shows.  If you
also have pre-recorded shows, you probably already get those
in digital (hopefully uncompressed) format.

Re: [ubuntu-uk] Fiddling with System

[Andrew Ball]

Hello Rob,

  RB I also tried this and I could get as far as getting
 things like mplayer working by specifying which
 desktop to use but I wasn't able to get independent
 mouse/keyboard control on that desktop using a USB
 mouse  keyboard.

If you have a VNC server instance running on the desktop
that you're trying to control, x2vnc might work.  My wife's
PC used to sit next to mine and every now and again I'd drag
my mouse pointer off the left-hand edge of my screen, onto
hers and start moving her windows around.  Perhaps you can
imagine how popular that made me.  :-)

Hope this helps,
  - Andy Ball

Re: [ubuntu-uk] Ubuntu CAD Alternative

[Andrew Ball]

Hello,

  PS This term often refers to 2D technical drawing
 programs such as AutoCAD etc. It can also refer to
 electronics design programs or 3D mechanical design
 programs.

It's years since I touched CAD stuff, but istr that
AutoSketch was AutoDesk's 2D drafting program and AutoCAD
was 3D.  Perhaps AutoCAD started out more like AutoSketch
though.

Re: [ubuntu-uk] Server OS Suggestion

Hello Dave,

  DW Why have ANY window manager on a server!?

Or X11?!  ;-)

Hello Matthew,

  ASB Or X11?!  ;-)

  MMW That one's easy, some of the PHP libraries that use
  GD and similar rely on the underlying X11
  functionality.

I use php, but what is GD?

Re: [ubuntu-uk] USB Network Cables

[Andrew Ball]

Hello Gav,

  GF A pair of USB wireless dongles or a USB to Ethernet
 adaptor for the Windows machine maybe?

I was going to suggest a PLIP cable, but then I
remembered that Microsoft Windows doesn't support PLIP.
There are USB PC-to-PC cables with open source drivers, but
I don't know whether Windows treats those as a network
interface, which should increase the odds of Linux talking
to the Windows box.  A FireWire cable is another option, if
both machines have the appropriate port.

Re: [ubuntu-uk] USB Network Cables

[Andrew Ball]

Hello Ian,

I was thinking of this...

  http://netbsd.gw.com/cgi-bin/man-cgi?upl+4+NetBSD-current

  ...which makes me wonder what chipset(s) are in the non-Prolific
cables.  Whether or not similar support is included in Ubuntu I can't
say because I have neither the cable nor an Ubuntu box on which to try
it.  Hopefully I can fix the lack of an Ubuntu box at least.
