finally the confusion is solved:
chinese checkers is not chinese:
http://en.wikipedia.org/wiki/Chinese_checkers
chinese chess is chinese, and comes from the same ancient indian game as occidental chess:
http://en.wikipedia.org/wiki/Xiangqi#History
http://en.wikipedia.org/wiki/Chess#History
http://en.wikipedia.org/wiki/Chaturanga
btw, chinese chess is called 象棋：
象 = elephant
棋 = board game
and in the indian game, one of the pieces was the elephant, later converted to a modern chess piece
矛 = spear
盾 = shield
矛盾 = disagreement
chinese disagreements are very serious! =)

Method of authentication in which password is MD5 hashed concatenated to a nonce, value given by the server open to be used only once. The client returns the MD5, and without knowing the password one cannot reproduce the MD5 for a given nonce.

Great http tutorial, looking forward to writing those requests by hand, and getting server output to my screen.
For Krusader users.
The bookmark system is fine, except for one serious flaw: if you want to rename the root of your directory structure, you have to modify all the paths one by one.
A workaround I’m using for this is to build my path step by step with environment variables and use single instance mode, aliases and the terminal emulator.
For instance, I put this on my .bashrc:
$A=a $B="$A/b" $C="$B/c" alias kra 'krusader "$A"' alias krb 'krusader "$B"' alias krc 'krusader "$C"'And to jump dirs just go to the embedded terminal emulator (open it with you shortcut, then control + down), and type the alias you want (kra for $A, and so on).
so if I want to rename “a” to “a2″, I only need to change “$A”, and all the others will be fine.
This is also a good method to set your $PATH variable.
Learning different languages teaches us about what is universal in human perception, and thus leads to common metaphors in both languages.
For example:
眼看 = very soon
眼 = eye
看 = see
Completely analogous to the English expression “At a glance”
Conclusion: what is the fastest thing that happens in human perception?
Seeing and understanding visual data, since both languages independently (probably, unlike say French and English which have enormous shared background) developed the same metaphor (as fast as looking and seeing)

if you ever meet 2 byte characters, that
suspect this encoding. It is quite common. For a list see

二十 = 20
三十 = 30
二三十 = around 20 or 30

make a multipage tex document with INPUT_PATH
INPUT_PATH="/path/to/tex/file/asdf.tex"compile with:
pdflatex -synctex=1 "$INPUT_PATH"this should generate “asdf.pdf” and the synctex file ( because of -synctex=1)
run synctex as
synctex view -i 77:1:/path/to/tex/file/./asdf.tex -o asdf.pdf77:1 means you are on line 77 column 1 of the tex file, and you want to get the position on the pdf. Note the ugly “/./” between the parent directory and the basename. It must be there!
sample output
This is SyncTeX command line utility, version 1.2 SyncTeX result begin Output:report.pdf Page:2 x:261.757507 y:492.330658 h:255.095062 v:495.319450 W:100.061378 H:13.902562 before: offset:0 middle: after: SyncTeX result end
amongst other things, this is telling you that this position on the tex file corresponds to Page 2 of your pdf.
Now all you have to do is to tell your pdf viewer to open that page. In Okular this would be:
okular -p 2 asdf.pdfBash suffers from a few disadvantages
which in my opinion make python a better choice for anything that is not a one liner.
On the other hand, learning bash and the basic Linux commands can be very useful for a programmer
sudo apt-get install fdupes
fdupes -rd dirA dirB dirCWill look for duplicates
echo 'cd ..' > test && chmod +x test./testdoes not nothing because ./test is executed is a subshell
. testworks, because the ‘.’ operator does does the same thing as copying the file test and pasting inside the current shell
Linux command line is such a powerhouse it already comes with a pdf command! pdf –help to learn of course
Useful, simple AND visually appealing. Beautiful. See Wiki link and by examples link.
Files:
find . -exec echo {} # outputs 'no-spaces' and 'many'
find . -exec echo "{}" # outputs 'no-spaces' and 'many and many spaces'
Same for xargs -I {}.
Use concatenation and escape the single quote outside:
echo 'asdf'''asdf' # prints asdf'asdf
Alt tab changes window groups, and alt backtick (‘`’, just above tab) navigates inside a given group of windows!! So useful.
If when you simply add skype command to the Startup applications, Skype does start-up, but there is no icon in the system tray, so that if you close the main window, or have the option to start in system tray, you cannot access Skype anymore with a GUI. Even worse, the Skype instance continues to run on the background, preventing you from opening a new one.
To me, the solution was instead of simply adding a command skype, to add
bash -c "sleep 10 && skype"
This waits for a bit before starting up Skype, so it seems that the problem was that Skype was starting up too early before some other necessary things were ready.

If that happens for any reason and if you can still boot, but get a broken interface (no mouse and keyboard for me) a possible solution is:
sudo apt-get -f dist-upgrade and follow the instructionsDO NOT TYPE THE NUMBERS ON THE KEY PAD, EVEN IF YOU ARE SURE THAT NUM LOCK IS ON WHEN YOU TYPE YOUR USERNAME!!!
Use the numbers above the letters instead.
!fooDoes the last command starting with `foo’. Source: this short and useful bash intro

With the script to follow you can do:
# changed lines only
# only in files .php
# under current dir
# but don't make them (0)
sed_multifile .php find replace 0
# make changes and list nothing (1)
sed_multifile .php find replace 1
# replace in all files
sed_multifile "" find replace 0
The script:
#!/usr/bin/env bash
usage()
{
echo "Usage: sed_multifile dotext find replace dosubstitute"
}
# argument checking
if [ $# -ne 4 ]
then
usage
exit
fi
# decide write or not
if [ $4 -eq 0 ]
then # don't replace
find . -type f -name "*$1" -print0 | xargs -0 sed -n "s/$2/$3/gp"
else # replace
find . -type f -name "*$1" -print0 | xargs -0 sed -i "s/$2/$3/g"
fi
Just add it to your bash search path.
