In order to be able to use the windows terminal application, you will need at least windows 1903 which is going to be released this month, in a matter of days.Define cognitive learning in psychology if you are like me and can’t wait until the official release of 1903, you can install windows insiders edition which will let you build and use the new terminal application today.Define cognitive learning in psychology if you already are on windows 1903, or up, you are good to go.

In this article, I will show you how to cross compile C and C++ programs on a x86-64 machine for raspberry pi using clang 8.Define cognitive learning in psychology the advantage of cross compiling on a x86-64 system for armhf is that, usually one has a beefy laptop or desktop computer that can speed up, by an order of magnitude or more, the compilation of C and C++ programs.Define cognitive learning in psychology this is more visible with large C++ programs, that can take hours to build on a raspberry pi 3 or days on a raspberry pi zero.

I recommend that you do the build in a debian stretch virtual machine or a docker container in order to not mess your system.Define cognitive learning in psychology if you decide to install stretch in a virtual machine, make sure to use the minimal netinst system. It is really important that you start with a bare bone system, because we need to install armhf executables and libraries.Define cognitive learning in psychology by using a minimal system we avoid potential conflicts with the native x86-64 versions.

This is a short note about measuring the execution time for a C program, or delaying the program execution for a specified amount of time.Define cognitive learning in psychology I’m only interested in using mechanisms that let us measure the execution time with at least millisecond resolution, so I won’t mention the classical C way of getting the time of day with second resolution time or using the clock function.Define cognitive learning in psychology

Since C11, the standard way to get a good time estimate is to use the timespec_get function, which returns the system clock time: 1 #include 2 #include 3 #include 4 5 int main ( void ) { 6 struct timespec t0 , t1 ; 7 8 if ( timespec_get ( & t0 , TIME_UTC ) != TIME_UTC ) { 9 printf ( "error in calling timespec_get " ); 10 exit ( EXIT_FAILURE ); 11 } 12 13 // do some work ... 14 15 if ( timespec_get ( & t1 , TIME_UTC ) != TIME_UTC ) { 16 printf ( "error in calling timespec_get " ); 17 exit ( EXIT_FAILURE ); 18 } 19 20 // calculate the elapsed time 21 double diff = ( double )( t1 .Define cognitive learning in psychology tv_sec - t0 . Tv_sec ) + (( double )( t1 . Tv_nsec - t0 . Tv_nsec ) / 1000000000L ); 22 printf ( "elapsed time: %lf seconds " , diff ); 23 }

In this article I will show you how to use ANSI escape codes to control the colors of your terminal, write text at arbitrary positions, erase lines of text or portions of the terminal and move the cursor.Define cognitive learning in psychology the advantage of using ANSI escape codes is that, today, these are available on most operating systems, including windows, and you don’t need to install third party libraries.Define cognitive learning in psychology these are well suited for simple command line applications. If you need to do complex text graphics check the ncurses library.

Start by downloading docker desktop for macos.Define cognitive learning in psychology if you don’t have a docker account, sign up for one it is free and it only takes a few minutes to create one. Once you are logged in, you should be able to get the docker app for macos.Define cognitive learning in psychology open the dmg file and drag the installer to your applications, you can safely accept all the default settings.

An interesting property of the singly linked list is that, in order to visit a certain node, you will need to pass through all the previous list nodes until the searched one.Define cognitive learning in psychology for example, if you want to print the third element of a singly linked list, you will need to start at the list head and pass through the first and second nodes.Define cognitive learning in psychology in other words, you can’t have random access to the singly linked list elements, like you can for example with an array. If you want to read more about the linked lists theory check the books recommended at the end of the article.Define cognitive learning in psychology

We are going to implement a C++17 file watcher that will monitor a given folder for file changes. For our limited purposes, we’ll monitor only the creation, modification and deletion of all files from the watched directory.Define cognitive learning in psychology the base folder will be checked for changes at regular time intervals and, in case of changes, we’ll run a user defined function.
