    Out of curiosity, can you share which application do you use to see all Chrome tabs and the other open programs when you tab?
    Looking forward to next episode.

    Nice tutorial, but why not use WebSockets ??? then you can simplify the usage to a webbrowser and less code 🙂

    Business Opportunity in Ruvol

    I have invented a Board Game [still unpublished and not yet out in the market] that I believe is guaranteed to be as challenging and exciting as CHESS. I called it “RUVOL.”

    It is my hope that one day Ruvol may surpass chess as the “Number One Board Game in the World.”

    The weakness of chess is it always starts in fixed positions that the opening moves become “memorizable.” In fact, not a few have so mastered the moves that they can play against their opponents “blindfolded.” It is for this very reason that the great Bobby Fischer introduced his so-called “Fischer Random Chess,” where the starting position of the pieces is “randomized” to make the memorization of openings impracticable. Fortunately, it is also for this reason that I invented Ruvol where “every game” has been calculated to be a challenging one to play.

    HOW IS RUVOL PLAYED and HOW YOU CAN MONETIZE IT?

    I detailed everything in my YouTube video. Here is the link: https://www.youtube.com/watch?v=jcqth0m3-R0

    BIG MONEY POTENTIAL IN RUVOL!

    It is worthwhile to note that the people who play chess will be the same people who will play Ruvol. In my Google search, I learned there are around 800 million chess players in the world. Even just a small percentage of these 800 million is good enough to earn big money from Ruvol either as an ONLINE GAME BUSINESS or as a PHYSICAL PRODUCT DISTRIBUTOR.

    Thanks and God bless!
