One of the really important rules of playing chess, in fact, the rule upon which the entire game hinges, is king safety. You can't make a move that puts your king in an unsafe position. This position of unsafe-ness is referred to as 'check'. If you can't find a way …

Oddly enough, I ran into this same problem while using SFML. Here in Qt-creator, I'm getting this error while trying to use a string. I declared something like so:

#include <QCoreApplication>

#include <QDebug>

#include <QList>

int main(int argc, char *argv[])

{

Last time I mentioned how the UCI (Universal Chess Interface) required two types of input, the FEN input, and a move by move input style. The second is rather interesting, especially for the internal chess board I have set up, because the input uses standard notation with alphanumeric characters.

While working with layouts in Qt creator, I ran into an interesting problem. I am trying to add my "gridLayout_2" (the box with 9 push buttons) into the "myGrid" (the box with 8 text labels). When I run this code:

#include "widget.h"

#include "ui_widget.h"

Another update to the BLOX2 (BLU Life One X2) kernel, I just added Sovoca's KCAL color calibration for the screen! You can check out the commit on GitLab, but unfortunately, while …

While building the picoEngine in C++, I will often be wondering what the engine is thinking. One of the problems is that I can not "see" the engine's board, so I don't know why it would make a particular move. So, I added a print function. This also is in …

While working through section 4 of my Qt GUI creator course, I ran into an interesting error:

/home/alaskalinuxuser/Documents/qt_course/section_4_21_qmainwindow/mainwindow.cpp:19: error: no matching function for call to 'QAction::QAction(const char [5])'
QAction * quitAction = new QAction("Quit");

What made the error interesting was that my …

Another update to the BLOX2 (BLU Life One X2) kernel, I just extended the voltage control from the big cores to the little cores as well! You can check out the commit on GitLab, but essentially we saw that the "bc" in the code stood for "big cores" and we …
