My eyes...

It's so hard to get starting to type... To write something... To complete a sentence in my mind and then put it on the screen... My eyelids closing with drug-induced sleep which is not sleep, I feel awake but my eyes want to close and then... Then what? Dream about something I won't remember even 5 seconds after I wake up with the alarms buzzing and beeping and screaming into my ears? It's so hard to put two and two together and come up with a description of the massive scene in my mind, leave alone a story plot... My eyes really want to close all by themselves so I do, my mind is numb but still running fast, no satisfying sleep is anywhere near. It's more like passing out eventually...

Fuck you Ubuntu, fuck you Shuttleworth!

Seriously? Tossers! Time to switch to something else. NOW!

Best late birthday present ever!

Ordered yanks ago, arrived yesterday, no HDMI/DVI to plugin but got SSH working! WHOHOOOO!!!

Compiling wspr & wsjt etc. on (x/k/l/)ubuntu

See here, excellent guide. This is on a i386 env based on that guide. Tested on Ubuntu 12.04.

Warning, this checks out trunk code so it might not work some days. Check out the development mailing lists / raise a bug / go have a cuppa and try a couple of days later.


sudo apt-get install subversion python-dev python-numpy python-imaging-tk python-pmw libportaudio2 portaudio19-dev libsamplerate0-dev gfortran cl-fftw3 python-dev build-essential

cd ~/wsjt-code

./configure --with-portaudio-lib-dir=/usr/lib/i386-linux-gnu --with-portaudio-include-dir=/usr/include && make && sudo make install



cd ~/wspr-code
./configure  --with-portaudio-lib-dir=/usr/lib/i386-linux-gnu --with-portaudio-include-dir=/usr/include  && make && sudo make install

but unfortunately it ignores the prefix for Python stuff. In the end I gave up on the prefix etc. and compiled it on the Eee 701 directly, wasting space on the packages. The original idea was to compile it on a 32-bit "development" VM and then copy stuff around. Anyhooow... The going is very slow on Eee, esp. with the fldigi running and decoding bpsk31 14.070 in the background. A lot of warnings are generated during the build.

I haven't compiled the rest. Maybe they will work.

Anyway, I have had problems running it off the installed path, also wsjt's startup script has some logic problems.

Simply run python wsjt.py or python wspr.py from the source directory and it all works fine!

Ben niye bi mok yazamiyom yaaa

Bu günlük iş yeter, saat 6'yı geçti, Radyo 4'teki 6:30 komedisini kaçırmadan eve gitmeli. Laylaylom, çanta toplandı. Tamam, pass, yarın görüşürüz İan... Ha? Ne? Almanlarda yine mi sorun çıkmış, tamam biraz hakkında konuşalım, ne yapabiliriz filan feşmekan, oki bu akşam bir bakarım serverlerine sorun çıkartıyor mu, 10'da mı duruyorlardı? Ha tamam, 9'da, saat farkı da var. Oki hadi bay! Çat küt araba kapısı. Ulan saate bak, 7 olcak neredeyse, direk eve. Çok acıktım. Telsizde bir şey duluyor mu bakalım tepeden aşağı inerken. 145.7375'te bir şey var ama pek anlaşılmıyor, çok fade in out var.... Neyse eve geldik zaten. Çat küt kapı. Yaa, evvelki hafta Freecycle'daki adamdan aldığım turntable hala arabanın arkasında yahu, dur onu da yüklenelim, spikerler kalsın şimdi, hepsini birden taşıyamam.

Off nasıl acıktım yaa, hemen hafta sonu dondurduğum yemeklerden birisini mikrodalgaya atalım ama önce laptopu açalım hazırlansın. Lay lay lom, bir podcast mı dinlesem o arada, bir BBC komedisi arşivlerden iyi gider. Yemeği de ısıttık yiyelim, bir yandan birikmiş Private Eye sayılarının birisini okuyayım.

and the other usual stuff.

When you get the nnfyboot error:

export LD_LIBRARY_PATH=$ORACLE_HOME/lib
ln -­s /usr/bin/basename /bin/basename
ln ­-s $ORACLE_HOME/lib/libclient10.a $ORACLE_HOME/lib/libagtsh.a

(Edit for 11.2.0.3)

mkdir /usr/lib64
ln -s /usr/lib/x86_64-linux-gnu/libpthread_nonshared.a /usr/lib64
ln -s /usr/lib/x86_64-linux-gnu/libpthread_nonshared.a /usr/lib64

Also see here for the following instructions:

During relinking operation OUI will fail and in $ORACLE_HOME/install/make.log  you will find following error.

/u01/app/dev/Middleware/agent11g/lib/libnnz11.so: could not read symbols: Invalid operation

collect2: ld returned 1 exit status

make[1]: *** [/u01/app/dev/Middleware/agent11g/sysman/lib/emdctl] Error 1

make[1]: Leaving directory `/u01/app/dev/Middleware/agent11g/sysman/lib'

Solution:

======

When you start to install with ./runInstaller, run in another terminal window (as root)

ls $ORACLE_HOME/sysman/lib/ins_emagent.mk

At first this will produce an error, as the installer wont have created this file yet.
Once the file exists, do:

vi $ORACLE_HOME/sysman/lib/ins_emagent.mk

Search for the line

$(MK_EMAGENT_NMECTL)

Change it to:

$(MK_EMAGENT_NMECTL) -lnnz11

What's more, insanely for some reason we could link Oracle libraries with the GCC 4.6 on 10.2.0.2 but not on 10.2.0.3. gcc is a symlink to /usr/bin/gcc4.6 by default.

apt-get install gcc-4.4
cd /usr/bin
rm gcc
ln -s gcc-4.4 gcc

once it's all linked w/o errors

rm gcc

ln -s gcc-4.6 gcc

and then retry and retry and retry. Insane!

Until Ubuntu gets Oracle certified, it's server won't be taken seriously. On the other hand, Oracle hasn't certified OEL6 with Oracle 11gR2 so I'm not taking Oracle seriously either.

VMWare ESX Killing trick

Nice way

• locate the VM:

  vmware-cmd -l

• Shutdown the VM:

   vmware-cmd /vmfs/volumes///.vmx stop

• Just turn the power off:

   vmware-cmd /vmfs/volumes///.vmx stop hard

Nasty way

   ps auxfww|grep 
  kill -9 

Skype, qjackctl and pulse notes

Tested on Dell Latitute and Asus Eee.

Also should work fine with any recording device (including on-board / webcam mikes), mixer is used to provide better mikes and multiple people recording).

Plug the UCA-202 into the laptop.

Setup

Add the following to .asoundrc:



hakan@hakan-laptop:23:28:55:~$ cat .asoundrc 
pcm.pulse {
    type pulse
}
ctl.pulse {
    type pulse
}
pcm.!default {
    type pulse
}
ctl.!default {
    type pulse
}

Start qjackctl and add the following to the execute script after startup bit:

pactl load-module module-jack-sink channels=2; pactl load-module module-jack-source channels=2;pacmd set-default-sink jack_out

Verify /proc/asound/cards and set the hardware to the correct one.

Then start up the jack daemon, open the connections, disconnect all.

Start up a 4-track Timemachine: timemachine -c 4

Connections

• Connect the PulseAudio Jack Sink left & right to Timemachine channels 1 & 2.
• Connect System-capture 1 & 2 to Timemachine channels 3&4.
• Connect System-capture 1 & 2 to Pulseaudio Jack Source channels left and right (so that Skype people can hear you talking via the mike).
• To monitor yourself, connect System-capture 1&2 to System playback 1 &2 (Folio Notebook master mix/tape button must be depressed to achieve this - which causes a lot of 50Hz hum), other mixer to be tested.

Power up the mixer, send the mike 1 to left channel, mike 2 to right channel. Test both channels to see if you are recording into Timemachine. 

Start Pavucontrol and mute all devices apart from the USB one. 

Set Pavucontrol Recording: Skype : Input from: Jack Source (PulseAudio Jack Source).

Set up a Skype test call and check if you can hear it via the mixer headphones and the mixer mike is played back to you. If you are using a second PC to test in the same room, Skype's echo cancellation makes it very tricky. Also make sure that the pavucontrol input volume is set to 100% at least to start with. 

Can't.... Write.... Block.... .

Things done today

Released a podcast, tidied up the place and rode to Hemel and had some beer with MehmetN. Lovely biking weather. Overall a satisfactory day.

TUC walk

I should have been in London today. With all these trips going on, I completely forgot about it. Darnit...

Votka

I really don't like it.

just maybe I complain too much

and just need a way to deal with all this shite?

Hobbies & Guilt

I've been reading the old entries here. I haven't done much lately. Today I tidied up the room. That's it. I mean, seriously. I plugged the new antennas in and listened to 20 and 40m but didn't transmit again. Last entry in the logbook is now years old. I've become a real lurker SWL. Some kind gentleman from Ofcom extended my reciprocal licence until 2016 so I don't have to worry about it for an other couple of years.

I spent some cash on vertical antennas for 20 and 6 meters and got a short vertical for 80m to 70cm and guess what, the stupid wire antenna around the room beats the lot for reception. I was hoping for something a bit better than that.

I haven't been writing, composing nor playing anything lately. I haven't taken the scope out for a year nor I have used the small scope nor binos for a coupe of months now. I haven't touched the camera for weeks until today (shot a couple of sun+cloud pictures through a dirty window).

I haven't found a new band to listen for a while and last time I went to a concert was Hawkwind in Cambridge and that was some damn time ago.

I've been reading a bit, at least I can say I've done that.

Tomorrow, a new day, hopefully.

Ubuntu Keyserver not accessible

Don't you hate it when this happens?

root@hakan-pc:~# sudo add-apt-repository ppa:libreoffice/ppa
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv 36E81C9267FD1383FCC4490983FBA1751378B444
gpg: requesting key 1378B444 from hkp server keyserver.ubuntu.com
gpgkeys: HTTP fetch error 7: couldn't connect to host

This usually happens because the keyserver port is blocked by a corporate firewall. You can use an other machine to fetch the keys and load them.

Sample here for the libreoffice ppa:

Grab the fingerprint from the ppa page, i.e., 36E81C9267FD1383FCC4490983FBA1751378B444

gpg --keyserver keyserver.ubuntu.com --recv 36E81C9267FD1383FCC4490983FBA1751378B444
gpg --export --armor 36E81C9267FD1383FCC4490983FBA1751378B444 > libreoffice_ppa.key
scp libreoffice_ppa.key targetserver:~/

on the target server,

cat libreoffice_ppa.key | sudo apt-key add -
apt-get update

All done.
