Private lessons in math - physics - engineering
I am an aeronautical engineer and I am well aware of the frustration of not achieving the desired academic results. I was here. A lot of times. I find it very satisfying to teach and to see how my students achieve their goals. I sincerely believe that learning is a privilege and a pleasure. It is my top priority that my students feel this. My level of mathematics, physics and engineering is very competent. Although of course, for very specific topics or doubts, I will have to analyze whether I am able to teach lessons with ease or not. Do not hesitate to write to me. I am used to working with people of different ages. I believe in segmentation, visualization of progress, objective results and practice. For students who have difficulty I analyze the root of learning problems. And, above all, I try to motivate them. An ideal lesson time would be distributed as follows: 20 minutes question and answer and start from these gaps, 30 minutes to advance, 10 minutes lateral thinking. Beyond these general lines, there is no rule or magic method. Some things work with some students and not with others. Adapting to needs is really the goal of private lessons. So I will do my best to find what motivates and helps my student.

installing and using a Linux-based distribution
You want to get out of the straitjacket imposed by Windows. I offer to install and help you use a Linux based distribution of your choice. Ubuntu, Linux mint or other type. All of these distributions are graphically very close to Windows and you won't be completely lost. You are a simple user of your computer, you do not have extensive computer knowledge! It doesn't matter, I'll show you how to best use your computer with this personalized training.

Elasticsearch Logstash and Kibana training for all levels
Elasticsearch is a NoSQL database whose particularity is to be able to index strongly text-oriented documents. You could think of it as a search engine, but you could set it up to exactly match your search needs. Elasticsearch is therefore a search engine capable of storing a large quantity of documents and which can be queried in real time. In addition, its query language provides interesting interrogation possibilities that can be exploited to extract statistics in real time. In this course I explain how you can design your Elasticsearch cluster in an efficient way and also use it to index / search your data.

HTML Classes for beginners and intermediates (You can even build your website on your own)
HTML is the standard markup language for Web pages. With HTML you can create your own Website. In simple words we can say, easiest and the best method to create a website. In the course duration, I'll be giving you live practical exposure so that you can actually experience and master over the concepts of HTML tags. Having years of work experience, I know how to start and build your concepts at a good pace. With the completion of this course, you'll be ready to build your own website. I am providing you a brief summary of our course which we generally follow but that doesn't mean that I am bound to just this much content. In case you have any doubt for any other specific topic related to the subject, you could always come up to me or you need any help in your assignments or projects, you are always welcome. Here is a brief overview of the topics we'll be covering : Introduction to HTML HTML Elements HTML Attributes HTML Headings HTML Paragraphs HTML Formatting HTML Fonts HTML Styles HTML Links HTML Images HTML Tables HTML Lists HTML Forms HTML Frames HTML Iframes HTML Colors HTML Colornames HTML Colorvalues HTML Quick List HTML Layout HTML Doctypes HTML Head HTML Meta HTML Scripts HTML Entities HTML URLs HTML URL Encode HTML Media HTML Audio HTML Object HTML Video HTML YouTube HTML GeoLocation HTML WebStorage HTML SSE HTML WebWorkers HTML Canvas HTML Plug-ins In case you have any query, please feel free to contact me.

Math For Minds (MFM)- class room , is a math class but in different show , it consists of several items , the most important is philosophical deep meaning and Engineering applied model for these tools. with more exercises, and too much assessment in training . we produce the meaning of mathematical skills .. And this is our Process " Skills Transferring " I Think That " You can choose teacher for any subject, Except math, You Need math skills transferring process developer"
