bibtex citation with author for IEEEtrans

Capital letter in bibtex

In bib file, add {} for the word with first capital letter,

e.g.

title="Controllable Fuzziness of General Fuzzy Numbers Addition Based on {Yager} T-norms",

then the title in Reference will display the Yager rather than yager.

Reomve obsolete packages

The 'rc' status means the configuration files of the removed packages are not removed. Issue the following cli command to remove them.

sudo dpkg -l|grep "^rc"|awk '{print $2}' | xargs sudo apt-get remove -y --purge

my new word is in ehchant

This file,/home/chiao/.config/enchant/en_US.dic contains my new words from lyx.

Beamer allowframebreaks

In LyX: DO NOT put brackets around allowframebreaks,

Show filename on top bar (lyx, kate, ...)

「系統設定值」->　「外觀」->　「運作方式」->「選單可見度」，點選「滑鼠懸浮時顯示」

Set table column spacing

Put this in TeX box : \setlength{\tabcolsep}{1pt}, e.g.

The pdf result is

One author et. al. setting in biblatex

Beamer compile error

This is caused by my installation of old beamer in /home/chiao/texmf.

/bin/rm -rf /home/chiao/texmf/tex/latex/beamer
/bin/rm -rf /home/chiao/texmf/tex/latex/pgf
texhash /home/chiao/texmf

latex code to word , libreoffice

In LyX, export (匯出) "MS Word Office Open XML". Then open it in word.
In LyX, export (匯出) "OpenDocument (Pandoc)". Then open it in libreoffice.

Break the long in-line math

If the in-line math contains too long expression, e.g, parenthesis, just add an math space in between the equality and the left parenthesis. Then the line will be broke at the math space. The following graph is the lyx source:

Note that there is math space. The following is the pdf graph.

Or put  \allowbreak in the place for breaking line, e.g. 

The pdf output is

Copy drupal from kpchiaoi5 to kpci7

In kpchiai5:

1. mysqldump -u drupaladmin -h localhost --skip-lock-tables -p drupal > drupal_20160826_kpchiaoi5.sql
2. gzip -9 drupal_20160826_kpchiaoi5.sql
3. sudo tar zcvf public_html_drupal_20160826_kpchiaoi5.tgz public_html/drupal

In kpci5:

1. download from kpchiaoi5: drupal_20160826_kpchiaoi5.sql.gz, public_html_drupal_20160826_kpchiaoi5.tgz
2. gzip -dc drupal_20160826_kpchiaoi5.sql.gz | sed -e '/^UNLOCK/d' -e '/^LOCK/d' > ~/a.sql
3. Using phpmyadmin to drop all drupal tables.
4. mysql -u drupaladmin -p drupal < ~/a.sql
5. sudo tar zxvfp public_html_drupal_20160826_kpchiaoi5.tgz -C /home/chiao
6. sudo chown -R www-data.www-data /home/chiao/public_html/drupal (IMPORTANT!!!!)
7. 6. 設定 -> 開發 -> 效能 -> 清除所有快取

For drupal having “htaccess: Options not allowed here” error

Edit /etc/apache2/mods-available/userdir.conf, add Options in AllowOveride, namely,

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 }
