So I am still using Ubuntu Gutsy and wanted to install the new version of geant4, which has migrated from is old build system to using CMake. I suppose this is long over due (as anyone knows who tried to build it 4 years ago). Here is what I had to do.

CMake upgrade to 2.8

First I needed to upgrade my version of CMake from their website and remove the old one.

wajig purge cmake
wget http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz
# then follow install instructions for cmake

Geant4 – First  build attempt

Almost … I get the following error

…
[ 81%] Building CXX object source/processes/CMakeFiles/G4processes.dir/transportation/src/G4UserSpecialCuts.cc.o
[ 81%] Building CXX object source/processes/CMakeFiles/G4processes.dir/transportation/src/G4VTrackTerminator.cc.o
Linking CXX shared library ../../outputs/library/Linux-g++/libG4processes.so
Error running link command: Argument list too long
make[2]: *** [outputs/library/Linux-g++/libG4processes.so] Error 2
make[1]: *** [source/processes/CMakeFiles/G4processes.dir/all] Error 2
make: *** [all] Error 2

Looks like there is just too many shared libraries in the compiling command! To see how bad it is check out the output

Googling… results in finding a similar error

As a user recommends I will try appending cmake flags (although this is not ideal)

-DBUILD_SHARED_LIBS=OFF -DBUILD_STATIC_LIBS=ON

Geant4 – Second  build attempt

Thinking it might be my old install, I commented all my geant4 settings from by previous install in my .bashrc file.

Using the command

cmake -DCMAKE_INSTALL_PREFIX=/path/to/geant4.9.5-install /path/to/geant4.9.5 -DBUILD_SHARED_LIBS=OFF -DBUILD_STATIC_LIBS=ON

we are not building the shared libraries (only the static). Need to find a fix for this. I think it is just my old kernel…

…
[ 98%] Building CXX object source/physics_lists/CMakeFiles/G4physicslists-static.dir/lists/src/MaxTimeCuts.cc.o
[ 98%] Building CXX object source/physics_lists/CMakeFiles/G4physicslists-static.dir/lists/src/MinEkineCuts.cc.o

Linking CXX static library ../../outputs/library/Linux-g++/libG4physicslists.a
[100%] Built target G4physicslists-static

Success!

My conclusion is that I cannot build the shared libraries because of my old system. If you know how to get around this please let me know.

Hooray! We just earned $60 billion dollars from the Saudi Government by selling all kinds of high tech weaponry to them. And by we I mean my fellow US citizens. What should we do with all this money? Shopping spree? How about a bomb shelter? But more important questions persist.

How many people will be killed with these arms?

SAUDI ARABIA ARMS DEAL DETAILS :

The U.S. is encouraging the Saudis to buy systems known as THAAD-Terminal High Altitude Defense-and to upgrade its Patriot missiles to reduce the threat from Iranian rockets. U.S. officials said it was unclear how much this package would be worth. [9]

Actually the THAAD system probably doesn’t work, why else would you need a warranty. From a technical point of view, THAAD  is incredibly challenging,  if not impossible, in its current for of existence. All you have to do is look at the language they use to describe their tests (even on wikipedia). During development

The Exchanged “Goods and Services”

• Buy 150 new and upgraded F15 fighters, dozens of Attack Helicopters [6]
• 84 new F-15 fighters [9]
• 70 upgraded F-15 fighters [9]
• 70 Apaches helicopters
• 72 Black Hawk helicopters
• 36 Little Bird helicopters    [9]
• HARM anti-radar missiles [10] ( nice name )
• Precision-guided JDAM bombs [10]
• Hellfire missiles [10]
• Sophisticated displays mounted on fighter pilots’ helmets [10]
• THAAD???

US gains from Sale

• A little bit of $$$ and
• more global waring

following the below instructions for EasyTag, I was able to have the same level of ease. The only exception would be that you have two steps (scan / rename),

It’s works in several stages.

First, select the files you want to move. If the tags are correctly written, then do: Scanner>>.Rename File(s) & Directory.

You need to use tokens to describe how you want the files to be renamed.

For example, to put them as ~/music/artist/album/song.mp3 you would use:

/home/yourusername/music/%a/%b/%t in the file name’ section.

It will show you underneath what the resulting filenames will be. Check they are OK.

Then hit the green icon at the top to the right of the “Scanner: Rename Files and Dir” box

That will NOT rename the files – they won’t be saved until you hit the ‘diskette’ icon on the main screen (not the scanner screen).

Once you do that, it will save the files to the new filenames & directories.

You can do this to lots of files at once, once yo have tried it on a few to make sure it does what you want.

It’s a bit cumbersome, but soon becomes routine, and for me has worked well.

The search string that I configured was: ‘/srv/downloads/new/audio/%a/%b/%a – %t’, and it was straighforward to figure out the macro legend (click ‘show legend’ within the search window)

I used: /media/sdc1/musical_arts/main/%a/%b/%a–%t and set file names to replace ‘ ‘ and %20 with an underscore, ‘_’.

Introduction

There are plenty of ways to define 3-dimensional geometries. Some are easy but limiting and some are very complex while providing limitless geometry configurations. Some cost thousands of dollars and require yearly licenses while others are free.

Here I try to document them and their compatibilities.

General

Virtual Geometry Model (VGM) – A nice translational library

C++ Based Models

• GEANT4 – Users Guide for Application Developers, Chapter 4
• ROOT – TGeo classes

XML Based Models

• GDML – Part of the CERN Simulation Project
• GraXML -

STEP

STEP is a standard for design and data exchange, as opposed to, say, Autocad’s formats which are are designed such that you cannot do this easily unless you fork over some money for their lousy software. Don’t use proprietary file formats.  If you are looking to start a project, requiring some 3D design, use an application that can import/export STEP! This will save you and everyone working on the project many headaches. STEP is growing so become familiar with it, especially if you are an architect or engineer! Check out this neat machining video.

The U.S. military are just murdering people!!! Too strong of words… tell me after you have seen the video. Two Reuters camera men killed. Cameras are weapons apparently. The military murder people trying to help the wounded. Two children are wounded.
