Install style files in LyX

http://flukylogs.blogspot.com/2009/09/install-style-files-in-lyx.html

LyX is a frontend to LaTeX and so installation of any style file in LyX essentially mean: (1) installation of that style file in underlying LaTeX; and then (2) getting that style file work in LyX (using LyX layout files). Installation method for different types of style files are given below:

Install LaTeX class (.cls)
create new directory with name under /usr/share/texmf-texlive/tex/latex/
copy .cls file (& other files, if present) in the new directory
sudo texhash
create  a file .layout in ~/.lyx/layouts
edit the layout file according to the instructions given in Chapter 5 of "Customizing LyX: Features for the Advanced User" (Help->Customization in LyX).
open LyX and click 'tools -> Reconfigure' and restart LyX when done. The new Document Class should be available now.
For Example, to install IEEEconf class file, download the zip files from here. Create .cls file by executing 'latex IEEEconf.ins'. Copy the folder IEEEconf to /usr/share/texmf-texlive/tex/latex/. Run sudo texhash. Find IEEEtran.layout file & copy it to a new file named IEEEconf.layout in ~/.lyx/layouts (IEEEconf and IEEEtran are very similar, so IEEEtran-layout file can be used as layout file for IEEEconf). Edit the the second line in IEEEconf.layout from
# \DeclareLaTeXClass{article (IEEEtran)}
to
# \DeclareLaTeXClass{article (IEEEconf)}
and it should turn up when you reconfigure LyX.

Install LaTeX style (.sty)

Style file (.sty) is an addition to class files (.cls) files and they provides special formatting rules which overrides the similar rules in class  files, if present. So each style file must be associated with a class file. Installation process is similar to that of class files (see previous section of this post). Layout files (step 5 above) have different format. Instructions are given in Chapter 5 of "Customizing LyX: Features for the Advanced User" (Help->Customization in LyX).

For Example, to install ACRA style file, download the files from here. Copy the file acra.sty to /usr/share/texmf-texlive/tex/latex/ACRA/. Run sudo texhash. Find article.layout file & copy it to a new file named acra.layout in ~/.lyx/layouts (acra.sty uses "article" class). Edit the the second line in acra.layout from
#  \DeclareLaTeXClass{article}
to
#  \DeclareLaTeXClass[article, acra.sty]{article (ACRA)}
Then add in next line

Preamble
    \usepackage{acra}
EndPreamble

and it should turn up when you reconfigure LyX.

Install BibTeX Style (.bst)
create new directory with name under /usr/share/texmf-texlive/bibtex/bst/
copy .bst file (& other files, if present) in the new directory
sudo texhash
open LyX and click 'tools -> Reconfigure' and restart LyX when done.
open LyX and click 'tools -> TeX Information' and choose BibTex Styles. Click 'Rescan' The new BibTeX should be available now.

XMind scroll problem

cgoise

View profile

More options Apr 7, 9:48 pm

XMind (and other Eclipse applications) do currently not show up in the
new global menu, which is used in Ubuntu Natty Narwhale (11.04).
See here: https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/688136
Workarounds for this type problems can be found on the following site:
http://askubuntu.com/questions/6784/is-it-possible-to-make-indicator-...

In essence: the command to run XMind from the command line is now:
"APPMENU_DISPLAY_BOTH=1 /usr/local/xmind/xmind"
(without quotes)

The site does not mention how to start applications affected by this
bug from the main menu, which requires a slightly different command.
This can be done by changing the command in the main menu to:
"/bin/sh -c  'APPMENU_DISPLAY_BOTH=1 /usr/local/xmind/xmind'"
(again without quotes).
The program 'alacarte' can be used for this, just as in previous gnome
version.

This specific setting (APPMENU_DISPLAY_BOTH=1) causes the normal AND
the global menu to be shown. It will be therefore noticed when the bug
is fixed, so the main menu can be resetted.

beamer->xouranl ->lecture

Recently I purchased Wacom Intuos4 small, which allows me to electronically write anything on digital note.  Windows has Windows Journal Note and Smartnotebook is an excellent software with 30 days of evaluation period.

On the other hand, Ubuntu provides the best solution since I am making my presentation slides using beamer.  Once you make a pdf file using beamer, open xournal on Ubuntu and just open the pdf file. The software xournal will smoothly convert the pdf to xoj format.  You can start lecturing!.

1. generate pdf using beamer or use any pdf file
2. start xournal and open the pdf file.
3. enjoy electronic writing!

So, simple and easy!

Submit a long running job via an LSF script file

2. Submit a long running job via an LSF script file

An alternative way of the bsub command line is to use an LSF script file as follows

Usage: bsub < jobfile

where the jobfile is a job script file. A sample LSF jobfile might contain lines like the following:

#BSUB -J jobname
#BSUB -oo outfile.%J
#BSUB -eo errorfile.%J
myprog

If you prefer to have the job output sent to you via email, you can specify an email address instead of specifying output and error file names:

#BSUB -J jobname
#BSUB -u userid@missouri.edu
myprog

You can also use #BSUB comments to specify any other bsub command options that you want to include, and multiple options can be specified on a single #BSUB comment line. An advantage of this method is that all the command options are saved in the job script file so that they are not forgotten.

How to includepdf files to SmartNotebook

I have landscape pdf files for teaching.  Here is steps to include the pdf file into SmartNotbook software.

1. Open a pdf file (landscape)
2. Rotate all the pages 180 degrees, so upside down.
3. Print the pdf to "SmartNotebook Document Writer" printer driver.
4. Once the pdf file is converted, it will be automatically loaded to SmartNotebook software in a correct way. Otherwise you have to rotate each page after loading.

The simplest way to print text and pdf files through ssh

If you want to print "b.pdf" to a remote Linux box connected to a printer, then

Linux / Unix Command: zip

When given the name of an existing zip archive, zip will replace identically named entries in the zip archive or add entries for new names. For example, if fooz.zip exists and contains foo/file1 and foo/file2, and the directory foo contains the files foo/file1 and foo/file3, then:

zip -r fooz foo

will replace foo/file1 in fooz.zip and add foo/file3 to fooz.zip. After this, fooz.zip contains foo/file1, foo/file2, and foo/file3, with foo/file2 unchanged from before.

How to use UHthesis2e in Lyx

=== Ubuntu ===

Become a root by
$ sudo bash

Go to the latex directory (/usr/share/texmf-texlive/tex/latex)
$ cd /usr/share/texmf-texlive/tex/latex

Make a uhthesis directory
$ mkdir uhthesis
$ cd uhthesis

Copy uhthesis setup files to the dir.
$ cp /somewhere/uhthesis2e.cls  ./
$ cp /somewhere/uht10.clo       ./
$ cp /somewhere/uht11.clo       ./
$ cp /somewhere/uht12.clo       ./


Go to
$ /usr/share/lyx/layouts
$ vi uhthesis2e.layout

Add following lines
#% Do not delete the line below; configure depends on this
#  \DeclareLaTeXClass[uhthesis2e]{article (uhthesis2e)}
# Input general definitions
Input stdclass.inc

Start Lyx and in Lyx
do: Tools > Reconfigure ; Restart Lyx.

And you will see "article (uhthesis2e)"
Now you should be able to use the document class in LyX as usual:
Document > Settings > Document Class > Document Class > article (uhthesis2e)


Download UHthesis2e.zip

gcc and OpenFOAM

I also find a couple of links that may be useful to you to compile gcc and OpenFOAM. (by Shengmeng at Platform Inc.)

(Link 1) http://www.cfd-online.com/Forums/blogs/wyldckat/385-automated-scripts-building-gcc-4-4-x-4-5-x-using-openfoam-1-7-series.html

(Link 2: discussion forum) http://www.cfd-online.com/Forums/openfoam-installation/73629-openfoam-installation-redhat-enterprise-linux-5-a.html

(Link 3: OpenFOAM in CentOS) http://sourceforge.net/apps/mediawiki/centfoam/index.php?title=Main_Page


I followed the steps in link 1 and so far so good.

First, Using yum in RHEL, I downloaded and installed flex, texinfo, byacc, and bison.

$ yum install -y flex flex++ --downloadonly --downloaddir=/home/albertsk/packages/
$ rpm -i /home/albertsk/packages/flex-2.5.4a-41.fc6.x86_64.rpm


$ yum install -y bison --downloadonly --downloaddir=/home/albertsk/packages/$ rpm -i /home/albertsk/packages/bison-2.3-2.1.x86_64.rpm 

$ yum install -y byacc --downloadonly --downloaddir=/home/albertsk/packages/
$ rpm -i /home/albertsk/packages/byacc-1.9-29.2.2.x86_64.rpm

Second, I downloaded  build-gcc_v4.tar.gz (5.7 KB, 12 views) and used the script to install other utilities such as gcc, gmp, mpfr and mpc.  During this process, I defined set FOAM_INST_DIR under my $HOME directory, which is quite important to "source etc/bashrc" for compiling environment.


Third, I went to OpenFOAM/OpenFOAM-1.7.1 directory and execute
$ ./Allwmake

which is still going on for about a half day. 


Fourth, later on I found that not all the executable files are built and got error message that says "/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found".  None of web information is directly useful, so I search the library and found an newer version at

ThirdParty-1.7.1/platforms/linux64/gcc-4.3.3/lib64/libstdc++.so.6.0.10



So, I copied libstdc++.so.6.0.10 to /usr/lib/ and make a newer link

ln   -sf   libstdc++.so.6.0.10   libstdc++.so.6

(The file libstdc++.so.6.0.10 should be copied to all the compute nodes and the link should be updated once a serial OpenFOAM test is done in fractal.)

Fifth, I got 4 errors in config such as

configure: error: no vtf3.h found; check path for VTF3 package first...
configure: error: no bfd.h found; check path for BFD package first...
configure: error: no libiberty.h found; check path for LIBERTY package first...
configure: error: no papi.h found; check path for PAPI package first...

This link seems to have a solution: http://www.cfd-online.com/Forums/openfoam-installation/80787-missing-vtf3-h-bpatch-h-papi-h.html

vtf3 library problem can be solved. See
http://anirban.org/cs521/ass7/
Download VTF library and extract & copy to a convenient location.

For bfd.h, it is found at
 /home/albertsk/OpenFOAM/ThirdParty-1.7.1/platforms/build-linux64Gcc/binutils-2.20.1/bfd/bfd.h
/home/albertsk/OpenFOAM/ThirdParty-1.7.1/platforms/linux64/gcc-4.5.2/include/bfd.h
/home/usr/local/binutils-2.21/include/bfd.h
Perhaps, these directories should be included in "INCLUDE" environment.

For iberty package, it is because binutils-devel is not installed.

Encoding from multiple input image files (JPEG, PNG, TGA, etc.)

http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html

6.8. Encoding from multiple input image files (JPEG, PNG, TGA, etc.)

MEncoder is capable of creating movies from one or more JPEG, PNG, TGA, or other image files. With simple framecopy it can create MJPEG (Motion JPEG), MPNG (Motion PNG) or MTGA (Motion TGA) files.

Explanation of the process:

1. MEncoder decodes the input image(s) with libjpeg (when decoding PNGs, it will use libpng).
2. MEncoder then feeds the decoded image to the chosen video compressor (DivX4, Xvid, FFmpeg msmpeg4, etc.).

Examples.  The explanation of the -mf option is in the man page.

Creating an MPEG-4 file from all the JPEG files in the current directory:

mencoder mf://*.jpg -mf w=800:h=600:fps=25:type=jpg -ovc lavc \
    -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

Creating an MPEG-4 file from some JPEG files in the current directory:

mencoder mf://frame001.jpg,frame002.jpg -mf w=800:h=600:fps=25:type=jpg \
    -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

Creating an MPEG-4 file from explicit list of JPEG files (list.txt in current directory contains the list of files to use as source, one per line):

mencoder mf://@list.txt -mf w=800:h=600:fps=25:type=jpg \
    -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

You can mix different types of images, regardless of the method you use — individual filenames, wildcard or file with list — provided of course they have the same dimensions. So you can e.g. take title frame from PNG file, and then put a slideshow of your JPEG photos.

Creating a Motion JPEG (MJPEG) file from all the JPEG files in the current directory:

mencoder mf://*.jpg -mf w=800:h=600:fps=25:type=jpg -ovc copy -oac copy -o output.avi

Creating an uncompressed file from all the PNG files in the current directory:

mencoder mf://*.png -mf w=800:h=600:fps=25:type=png -ovc raw -oac copy -o output.avi

Note

Width must be integer multiple of 4, it is a limitation of the RAW RGB AVI format.

Creating a Motion PNG (MPNG) file from all the PNG files in the current directory:

mencoder mf://*.png -mf w=800:h=600:fps=25:type=png -ovc copy -oac copy -o output.avi

Creating a Motion TGA (MTGA) file from all the TGA files in the current directory:

mencoder mf://*.tga -mf w=800:h=600:fps=25:type=tga -ovc copy -oac copy -o output.avi

Subversion Commands and Scripts

 Basic SVN Commands
http://www.linuxfromscratch.org/blfs/edguide/chapter03.html

svn status

svn status. This command prints the status of working directories and files. If you have made local changes, it'll show your locally modified items. If you use the --verbose switch, it will show revision information on every item. With the --show-updates (-u) switch, it will show any server out-of-date information.

$ svn ci -m " any message"
$ svn update
$ svn status

will show files that are not subversioned with "?" in front.

Reference sheet for natbib usage

http://merkel.zoneo.net/Latex/natbib.php

The natbib package has two basic citation commands, \citet and \citep for textual and parenthetical citations, respectively. There also exist the starred versions \citet* and \citep* that print the full author list, and not just the abbreviated one. All of these may take one or two optional arguments to add some text before and after the citation.

\citet{jon90}	-->	Jones et al. (1990)
\citet[chap. 2]{jon90}	-->	Jones et al. (1990, chap. 2)
\citep{jon90}	-->	(Jones et al., 1990)
\citep[chap. 2]{jon90}	-->	(Jones et al., 1990, chap. 2)

3. Make the pre-revprop-change hook script executable: chmod +x PATH/hooks/pre-revprop-change
4. Initialize svnsync: svnsync init file:⁄⁄⁄PATH URL_TO_REPO_ROOT_TO_CLONE
5. Synchronize: svnsync sync DEST_URL

(Note: "DEST_URL" is the url to the Subversion repository you created in step 1.)

How to install OpenFOAM in Mac

Preparations

1. Obtain the necessary software through MacPorts.
   • libtool
2. Obtain the latest version of XCode.
   • This may be available on your Max OS X Install CD/DVD.
   • Available online at http://developer.apple.com/technologies/xcode.html.
     • Note: You will need to sign in with your Apple ID and password to access the download.
3. Obtain the latest version of XQuartz from http://xquartz.macosforge.org/.
4. Obtain the latest version of Qt from http://qt.nokia.com/downloads/qt-for-open-source-cpp-development-on-mac-os-x.
   • Note: You do not need the full SDK. The "QT libraries" download is sufficient, and will include qmake.
5. Obtain the latest version of CMake from http://www.cmake.org/cmake/resources/software.html

here we go.

But I was NOT able to install OpenFOAM on my Mac.

Installation of Elmer CFD using Intel Compilers ver. 12

All most all routines are compiled with some warning and recommendation messages.

Two key things should be done to compile files in fem/src.

1. "CONTIGUOUS" option should be disabled in configure files, Makefile files, and especially acx_elmer.m4.

2. The following directory should be included in $LD_LIBRARY_PATH

/opt/intel/composerxe-2011.2.137/compiler/lib/ia32/

3. By running 'make check' in fem, I got 154 passes out of 163:

capturing messages from configure and make

To capture the output of the configure and make steps you can use the script command or the following technique if using a Bourne style shell:

shell$ ./configure {options} 2>&1 | tee config.out
shell$ make all 2>&1              | tee make.out
shell$ make install 2>&1          | tee make-install.out

or if using a csh style shell:

shell% ./configure {options} |& tee config.out
shell% make all              |& tee make.out
shell% make install          |& tee make-install.out

Best Practice for Patching Individual Packages in PCM

Issue Description

I need to update the kernel package on my PCM cluster with the latest and greatest avaialbe on RHN.

Solution Detail

Often, it is necessary to apply patches to your PCM cluster. Some patches fix security issues, while other patches offer bug fixes and feature improvements. Patches can be applied in two ways.

1.     One way is to use kusu-repopatch tool to download and install all available patches for your Operating System. This has the advantage of having your cluster nodes always at the "latest and greatest" version level. There are a few down sides with this approach, namely that updating large number of packages is more risky and can break your production environment, and also if you are using Platform OFED for InfiniBand support, kusu-repopatch cannot be used due to dependency issues. This last point is only valid for PCM versions < 2.1. In 2.1, this issue is addressed, and kusu-repopatch can safely be used even with Platform OFED kit installed.

2.     The other way is to download the individual packages manually using yum command, and then add them to your PCM repository. The advantage is that updates can be done very quickly and relatively safely. The disadvantage is that not all of your packages are at the "latest and greatest" version level.

This article describes the second approach, That is, how to patch individual packages in your PCM cluster. As a working example, the article shows how to patch the kernel package.

If you are interested in using kusu-repopatch to patch all the packages, please refer to the article titled "Best Practice for Patching PCM Clusters with kusu-repopatch."

0. Before you begin

Before applying any patches to your production environment, you should take some precautions in case something goes wrong. In your PCM cluster you can take advantage of repository snapshots and node group templates to apply your updates in a safe way.

NOTE: In older version of PCM (< 2.0) the above commands did not have the "kusu-" prefix. For example, repoman vs. kusu-repoman. To determine which version of PCM cluster you are using,you can look at the output of cat /etc/kusu-release.

1.     Use kusu-repoman command to get the name of your production repository. For example,

pcm201installer:~ # kusu-repoman -l
Repo name:      sles-10.3-x86_64
Repository:     /depot/repos/1000
Installers:     192.168.1.1;172.27.1.43
Ostype:         sles-10-x86_64
Kits:           base-2.0-1-x86_64, sles-10.3-x86_64,
                nagios-2.12-7-x86_64, ofed-2.0-1-x86_64,
                PCM_GUI-2.0-1-x86_64, platform-hpc-2.0-2-x86_64,
                platform-isf-ac-1.0-1-x86_64, platform-lsf-7.0.6-1-x86_64,
                platform-mpi-7.1-1-x86_64, platform-rtm-2.0.1-1-x86_64

The name of the repository is sles-10.3-x86_64, and it has an ID of 1000. The repository is located under /depot/repos/1000/ directory, and it was created during PCM installation.

2.     Create a snapshot of your production repository with kusu-repoman command. This will create a new repository with ID 1001 under /depot/repos/1001/ directory.

# kusu-repoman -r -s

3.     Create a new node group which is a copy of your production node group with kusu-ngedit command. You can use kusu-nghosts -l command to determine the name of your production node group, first. Then, use kusu-ngedit to create a copy called compute-patchtest, like this:

# kusu-ngedit -c compute-rhel-5.4-x86-64 -n compute-patchtest

4.     Associate the compute-patchtest node group with snapshot repository using the kusu-ngedit command.

5.     Move a single node to compute-patchtest node group using kusu-nghosts command.

1. Register with Red Hat Network (RHN)

Fist step is to to register your cluster to Red Hat Network. If you are using SLES, then please use equivalent procedure to register for online updates. If you are using CentOS or SCL, then you do not need to register your cluster, but you might need to enable the online repository in /etc/yum.repos.d/ directory.

Do following to register your cluster with RHN:

1.     run rhn_register on your Installer node

2.     Update the /opt/kusu/etc/updates.conf file and enter valid username/password to login to RHN as well as Server ID (a.k.a RHN System ID).

NOTE: Server ID is not needed if you are running PCM version < 2.0.

2. Download and Install the Patches

Yum will, by default, download and install the updated packages. However, since PCM will be responsible for installing the updated packages on cluster nodes, we just need yum to download the package, and not install them. For this, you need to download the downloadonly plugin for yum. Follow these steps to download and install the kernel patches.

1.     Download the downloadonly plugin from RHN:

# yum -y install yum-downloadonly

2.     Create a snapshot of your production repository. Best practice is to always test the updates prior to applying them to production repository. Therefore, you should first create a snapshot of your production repository and .....

3.     Download latest kernel packages from RHN. There are three packages which you must update: kernel, kernel-devel and kernel-headers. The packages must be downloaded to /depot/contrib/1001/ directory; this is where PCM will look for custom RPMs associated with snapshot repository (id = 1001).

# yum update -y kernel kernel-devel kernel-headers --downloadonly --downloaddir=/depot/contrib/1001/

4.     Update the snapshot repository:

# kusu-repoman -ur "name of snapshot repository"

This will create appropriate symbolic links in /depot/repos/1001/Server/ directory, and it may take up to 10 minutes to complete. The symbolic links to the latest kernel packages are shown below:

[root@pcm201installer ~]# ll /depot/repos/1000/Server/kernel-*
lrwxrwxrwx 1 root root 59 Oct 21 12:13 /depot/repos/1000/Server/kernel-2.6.18-194.17.1.el5.x86_64.rpm -> ../../../contrib/1000/kernel-2.6.18-194.17.1.el5.x86_64.rpm

lrwxrwxrwx 1 root root 65 Oct 21 12:13 /depot/repos/1000/Server/kernel-devel-2.6.18-194.17.1.el5.x86_64.rpm -> ../../../contrib/1000/kernel-devel-2.6.18-194.17.1.el5.x86_64.rpm
lrwxrwxrwx 1 root root 67 Oct 21 12:13 /depot/repos/1000/Server/kernel-headers-2.6.18-194.17.1.el5.x86_64.rpm -> ../../../contrib/1000/kernel-headers-2.6.18-194.17.1.el5.x86_64.rpm

5.     Install the patches on nodes in the compute-testpatch node group. Use the kusu-cfmsync command to install the patches "on-the-fly" - there is no need to re-provision the nodes to install the patches in PCM. However, if you have patched the kernel, you need to reboot the nodes using kusu-boothost command to boot them with the new kernel.

# kusu-cfmsync -n compute-testpatch -u
# kusu-boothost -r "hostname of patched node"

3. Test the Patches and Install in Production Environment

The only thing that remains is to test the patches work ok for nodes in compute-testpatch node group. Do as much testing as required to convince yourself that your production applications will work with OK after the patches were applied. For example, you may wish to do the following tests:

• Test that nodes in compute-testpatch node group can be re-provisioned correctly
• Test that patched packages are installed after re-provisioning. For kernel patches, run uname -r command to make sure kernel version is the latest one.
• If you have patched the Installer node as well, then you can run command like kusu-genconfig nodes and make sure you get a list of all node hostnames in you cluster. This will confirm that PCM tools can communicate to the cluster database

Once you are satisfied that the patches are safe to roll out to your production environment, you can follow the steps outlined in section 2 "Download and Install the Patches" to patch your production repository. The only difference is that now you should specify your production node group and installer node group name when you apply the updates via kusu-cfmsync -u
