Prevent dash on the repeated author for IEEE bibliography

The following might not be work. Try my another blog:

https://kpchiaoo.blogspot.com/2019/07/bibtex-citation-with-author-for.html

1. Put the following line inside bib file, @IEEEtranBSTCTL{IEEEexample:nodash,CTLdash_repeated_names = "no"}
2. Put the TeX ERT inside lyx file contains
   \bstctlcite{IEEEexample:nodash}
3. Make sure "nodash" in both files are the same
4. Or edit IEEEtrans.bst, change # 1 to #0 as follows:

   % #0 turns off the "dashification" of repeated (i.e., identical to those
   % of the previous entry) names. The IEEE normally does this.
   % #1 enables
   FUNCTION {default.is.dash.repeated.names} { #1 }

Octave produce blank fig (xfig) file in ubuntu 18.04

I have a post in http://octave.1599824.n4.nabble.com/Cannot-produce-fig-file-td4687972.html#a4688009.

The reason why fig cannot be created is due to the bug in ghostscript 9.22.  
I found a solution (temporarily) in ubuntu 18.04. The steps are:

1. Download the ghostscript 9.23  here
2. Untar it at, say, /foo/.
3. sudo mv /usr/bin/gs /usr/bin/gs_orig_922
4. sudo ln -sf /download/Ghostscript/ghostscript-9.23-linux-x86_64/gs-923-linux-x86_64 /usr/bin/gs
5. Done!

Convert vmdk for using in ESXi

The vmdk file, e.g, created in vmware workstation, cannot be directlt used in ESXi. It needs to be converted. The process is:

1. Enable ssh connection in ESXi host.
2. ssh to ESXi host, e.g. ssh -l root 192.168.1.110
3. cd to the directory containing the vmdk file, e.g.
   cd /vmfs/volumes/62169753-c96da716/vmdk
4. Suppose the vmdk file is ubuntu.vmdk, and let the converted vmdk filename be ubuntu_convert.vmdk. Then issue the command,
   vmkfstools -i ubuntu.vmdk ubuntu_convert.vmdk -d thin
5. It will show something like:
   ...
   Clone: 100% done.
   It does not mean thee conversion is really finished. Just wait until the shell returns prompt, e.g. [root@chiao-dell:/vmfs/volumes/62169753-c96da716/vmdk]
6. Usually, it will take couple of hours to finish for large file, YES! H.O.U.R.S. !
7. If the datastore in on an nfs server, e.g. 192.168.1.8, then get into the nfs directory and use the following command to display the converted file size.
   ls -lsh ubunut_convert-flat.vmdk
   You will see something like this line:
   2.0G -rw------- 1 myuid mygid 510G  8月  8 16:27 ubuntu_convert-flat.vmdk
   Keep running this command, the size at the front is increasing.
