Bash - useful bash aliases which I use in my daily work

~/projects/CppAdventureExamples/bash/aliases.html Bash alias is abbreviation of one terminal command (usually long command) using other terminal command (usually much shorter command). We can define aliases in bash dot files (ex. ~/.profile file).

Example of bash alias: 
alias i="sudo apt-get install"
Then we can install 'vim' package using 'i' alias this way (it works of Debian-based systems): 
i vim
Today I would like to present few useful bash aliases which I use in my daily work.
You can paste below aliases into your ~/.profile file (or ~/.bashrc) if you recognize them useful for you.
Enjoy!
#==================================================================
# Listing aliases 
alias ll="ls -lah"
#list only directoriesj
alias lsd="ls -lF ${colorflag} | grep --color=never '^d'"
alias sl='ls'

#==================================================================
#filter selected app from running commands 
alias pg="ps aux --sort=start_time | grep"
#list all apps runned by me and sort by start time
alias pm="ps aux --sort=start_time | egrep '^$USER'"

#==================================================================
# BUILD ALIASES
# speed up make + make install using all available CPU cores
alias mi="make -j`nproc` && sudo make -j`nproc` install"

#==================================================================
# OTHER ALIASES
# show last notes to syslog file quickly 
alias lg="tail -f /var/log/syslog"
# speed up wget in parallel (on 16 threads)
alias wgetp="aria2c -x 16 -s 16"
#generate 12-character long password 
alias passgen="strings /dev/urandom | tr -cd '[:alnum:]' | fold -w 12 | head -n 1"
# retart apache2 server
alias aprst="sudo /etc/init.d/apache2 restart"
# show open ports
alias ports='netstat -tulanp'
# ps 10 memory and cpu consuming processes 
alias psmem='ps auxf | sort -nr -k 4 | head -10'
alias pscpu='ps auxf | sort -nr -k 3 | head -10'

Advanced C++ - Stack unwinding

Stack unwinding is normally a concept of removing function entries from call stack (also known as Execution stack, Control stack, Function stack or Run-time stack). Call Stack is a stack data structure that stores active functions' addresses and helps in supporting function call/return mechanism. Every time when a function is called, an entry is made into Call stack which contains the return address of the calling function where the control needs to return after the execution of called function. This entry is called by various names like stack frame , activation frame or activation record. With respect to exception handling , stack Unwinding is a process of linearly searching function call stack to reach exception handler. When an exception occurs, if it is not handled in current function where it is thrown, the function Call Stack is unwound until the control reaches try block and then passes to catch block at the end of try block to handle exception. Also, in this proc...
