Too many kids as well as teenagers and adults have problems with study. Today's meetup will inform you about the basics in STUDY TECHNOLOGY that provides an understanding of the basics of learning and supplies exact ways to overcome all the pitfalls one can encounter during study. This is applicable to young children, teenagers (or their parents that are trying to help them) and adults alike. Study Technology shows how one studies in order to comprehend a subject so one can apply it. Laws on which learning is based and workable methods have also been discovered for anyone to apply for themselves or when teaching others. Too many students graduate from school and college unable to put to use what they’ve learned in school. It’s not that they’re stupid or that their teachers didn’t know how to teach. More than likely it traces back to the one thing missing from most educations—learning how to learn in the first place. We all went to school, yet isn’t it odd that no one taught us how to study? The information presented at this meetup can help anyone improve others or his own ability to learn. It is a practical tool that parents and teachers alike can use to enhance a child's study performance. You’ll learn the barriers that lie between your own or a child's education. And you will very quickly learn how to overcome them. This technology will enable you or a child to pursue any subject with skill and confidence. Teachers who have "hard to handle/distributive " or slow learners in class will absolutely love the amazing turn around most often seen in improved behaviour and student performance in class. If you or your child has difficulties at school (or learning new things at work or online) than this meetup is important to you. If you can not make it to our meetup than contact the organizer and arrange it to suit your time. This technology can if one was to live far away be taught online. (extension course) You may offcourse also opt to have this technology taught to your own child by experienced volunteeer staff or learn about this yourself and transfer this knowledge to those you want to have better grades. Yes it is possible to improve anyone's study performance. All it takes is just 5 steps. See you at this meetup. Pam

The optimum computing machine is a subject many of us have studied. If you were building one how would you design it? First the computer should be able to compute with perfect accuracy on any problem in the universe and produce answers which were always and invariably right. Second the computer would have to be swift, working much more quickly than the problem and process could be vocally articulated. Third the computer would have to be able to handle large numbers of variables and large numbers of problems simultaneously. Forth, the computer would have to be able to evaluate its own data and there would have to remain available within it not only a record of its former conclusions but the evaluations leading to those conclusions. Fifth, the computer would have to be served by a memory bank of nearly infinite capacity and would have to be available to the analytical portion of the computer in the smallest fractions of a second. Sixth, the computer would have to be able to rearrange former conclusions or alter them in the light of new experience. Seventh, the computer would need no exterior director, but would be entirely self determined about its programing guided only by the necessity –value of the solution which it itself would determine. Eight the computer should be self servicing and self arming against present and future damage and would be able to estimate future damage. Ninth the computer should be served by perception by which it could determine necessity –value. Tenth ,the memory bank should store perceptions as perceived ,consecutive with time received with the smallest possible time divisions between perception .It would then store in color-Visio (moving),tone audio (flowing),odor ,tactile and self sensation ,all of them cross –coordinated . Eleventh, for the purposes of solutions, it would have to be able to create new situations and imagine new perceptions hitherto not perceived and should be able to conceive these to itself in terms of tone –audio ,color-visio ,odor, tactile, and self sensation –and should be able to file anything so conceived as imagined ,labeled “memories” Twelfth, the entire machine should be portable. It might be somewhat astonishing at first to conceive such a computer .But the fact is, the machine is in existence .There are billions of them in use today and many ,many more billions have been made and used in the past . In fact you’ve got one .for we are dealing with the human mind. L.RON .HUBBARD Do you want to learn how the mind works?Then do not miss this meetup. RSVP now !!

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
