Summer photo updates

http://www.dspsrv.com/~jamesc/photos/

I just put some photos on the web this night.
And mailed them to some people.

Holidays in Holland.
Two days in Rotterdam.
10 days in De Lage Vuursche and visit Baarn. And Rachel visits us.

We meet Siebe (and Hidde and Benthe) in Utrecht.
We go on a pedal boat with Hans and find Blackberries.

We stay 4/5 days in Duinrell (Wassenaar) and then fly home from Schiphol.

Trains and buses everywhere.
Good fun actually.
Moving suitcases quite manageable really.
I had the heavy green one, Daire the big orange one, Fionn had buggy+Maeve+Kate.
Steps/lifts in train stations were the most awkward thing.

installing git (and in particular git-svn on solaris)

This might make you really really glad you use a linux with a sane package manager!
Thanks to anyone who wrote on solving Error.pm/SVN::Core.pm problem on the internet.
That helped!

I had one same^H^H^Himilar issue on cygwin and solaris
I want to use git-svn.

cygwin just had one error "Can't locate SVN/Core.pm" (git package was installed).
This solved by installing the additional subversion-perl package.
$ cygcheck.exe -l subversion-perl


solaris (as usual! was more difficult) ... :-E

solaris 10 opensolaris/blastwave doesn't have a git package !? :-o (for intel/amd)
So I have git installed using sunfreeware packages
http://sunfreeware.com/programlistintel10.html#git
AND make sure all the dependancies are installed from SFW also, see the minor grief I had below missing expat (not for git itself but for getting perl Alien::SVN to compile so I could get git-svn working)

First error "Can't locate Error.pm" solved easily enough.
$ wget home.comcast.net/~ericblake/Error.pm
And copy to somewhere in $PERLLIB path.
$ cp Error.pm /usr/perl5/vendor_perl/

Next error "Can't locate SVN/Core.pm"

$ perl -MCPAN -e shell
cpan> install Module::Build
cpan> install Alien::SVN
didn't work :( didn't like /usr/sfw/bin/gmake :(

Manifying blib/man3/Alien::SVN.3
/usr/bin/perl "-Iblib/arch" "-Iblib/lib" Build.PL Build
Too early to specify a build action 'Build'. Do 'Build Build' instead.

incidentally, $(/usr/sfw/bin/gmake --version) == "GNU Make 3.81"

$ ./Build

meh. :-7 mixing packages from CSW and SFW would be a bit messy
get and install SMCexpat (from sunfreeware)
now:

$ ./Build
looks better, goes further
... but linking problems
cc: Warning: option -- passed to ld


Oh right. It used sun compiler throughout.
Back to configure.
$ perl Build.pm
Would you like to pass any arguments to configure? [--libdir=/usr/perl5/site_perl/5.8.4/i86pc-solaris-64int/Alien/SVN --prefix=/usr/perl5/5.8.4 ]CC=/usr/sfw/bin/gcc

I bet if I just took the perl files from Cygwin or linux it would have done the same job ... !?

AUGHGHGHGHGHH!

reinstall svn sunfreeware package,

svn okay now but git svn still has lib problems

$ git svn clone https://$MYREPO --trunk=trunk --branches=branches --tags=tags
ld.so.1: git-hash-object: fatal: relocation error: file /usr/local/bin/git-hash-object: symbol deflateBound: referenced symbol not found
Can't use an undefined value as a symbol reference at /usr/local/lib/perl5/site_perl/5.8.8/Git.pm line 421.

HA! deflateBound is in libz

I'm so STUPID! Get zlib from sunfreeware (remember what I said earlier about ALL dependancies!!)


and I'm running with this
$ export LD_LIBRARY_PATH=/usr/local/lib:/usr/sfw/lib:$LD_LIBRARY_PATH
probably don't need that but was picking up libgcc, libiconv from /opt/csw instead of /usr/local


So in conclusion: Alien::SVN (which provides SVN::Core) is quite awkward to build for solaris (gmake, cc vs gcc and lib differences on solaris)

etymology of jargon

etymologically interesting

Anything self-referential is amusing (blame/praise starts with GEB - how can one describe systems purely if you have any use/reference of anything in that system in the description of the system - HAHAHAH!) like a joke or pun. Etymology of words about language, jargon: old french jargon garrire bird-chatter gargle. from http://www.etymonline.com/index.php?term=jargon

http://catb.org/jargon/html/introduction.html
http://catb.org/jargon/html/distinctions.html
"communication, and of inclusion, and of exclusion."
And for hacker jargon as a technical language there is a complex level of detail which does seperate it from being just a plainer slang. Not easy to learn/understand unless you learn the whole culture (shared consciousness), descriptive of complex/different ideas/models/thinking... which is very useful and important for facilitation of communication, quite like a real language.

Oh yeah! so elitist :) too.

"we have attempted to ensure that everyone's sacred cows get gored, impartially. Compromise is not particularly a hackish virtue, but the honest presentation of divergent viewpoints is."

This digression started with http://www.faqs.org/docs/jargon/H/hexadecimal.html
"correct term for base 10, for example, is ‘denary’"

   ~"etymologically pure"~   real live language   decimal style words   "too racy and amusing for stuffy IBM", (incorrect and inconsistent anyway! :))
2  binary                    binary
3  ternary or trinary        ternary
8  octonary                  octal                octaval
10 denary                    decimal              decimal

library-check.pl, postfix config to forward/relay mail to smtp server

1. Move across library-check.pl script from suse to ubuntu
2. enable mail from command-line and perl WWW::Mechanize script dependancies
3. solve postfix trouble (i.e. config postfix properly)
4. WAH! 5 + 6 books two accounts 5*23 + 6*29 days overdue. oops.

brazil nuts, garden stones and avalanches

Isn't it annoying that garden/fields seem to grow stones.

"Avalanches are gravitational granular flows,"

"When the avalanche flows over a terrain feature (steeper slope or surface irregularities), the flow can become turbulent (mixing) causing the victim to be pushed down. As the flow smoothes out, it is the particles segregating (de-mixing) that force the person back to surface."

"When an avalanche slows (but before it stops), the snow fragments interlock, resulting in a
change in state from a fluid-like flow to that of a sliding block (everything moves as a single unit or block)."

So. Esentially. Keep arms near face somehow.
