Blockchain Essentials: Crash Course on the Technology

in progress for now
A blockchain is a type of distributed ledger technology (DLT) that consists of growing list of records, called blocks, that are securely linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). The timestamp proves that the transaction data existed when the block was created. Since each block contains information about the previous block, they effectively form a chain (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.

Uni Mathe, A-Levels, Matura etc., by a Cambridge Grad
A Cambridge and UniVie Grad and a soon-to-start PhD student in Computer Science and Mathematics at ISTA to teach Maths, Stats, CS and/or Computational Biology/Programming modules. Ich spreche auch Deutsch und kenne mich mit dem Schulmaterial (z.B. Matura) und Modulen aus Uniprogramm (BSc Mathe auf Uniwien) aus. If your goal is not just to learn some formulas by heart, but to gain a deep insight into how mathematical topics are interconnected, or to get a hand at coding and how to think algorithmically to solve complex tasks – I am just the right fit for you or your child. Additionally, I am personally familiar with the British educational system – from A-Levels (3 x A*) to University (MSc/MPhil from Cambridge with distinctions).

TRAINING TO EMBODY EFFECTIVE MANAGERIAL COMMUNICATION IN THE PROFESSIONAL FRAMEWORK
➤ Being a good manager is also being a good communicator. After all, a strategy can only be put into practice if you show yourself capable of interacting with your employees, of being a source of inspiration for them and of listening to their concerns. Unfortunately, not all managers naturally excel in this role and their difficulties in asserting themselves as true leaders is often attributable to their difficulties in communicating. ➤ The objective would then be to explore together the areas of improvement in terms of communication know-how. And managing effectively requires specific and advanced know-how. ➤ In fact, managerial communication corresponds to the interactions between the management of the company and the organization and more specifically, between the manager and his team. This executive is in charge of transmitting information and directives from higher hierarchical levels, supporting internal communication, distilling messages related to his own management to obtain the commitment of his team, all while transmitting a message effectively. ➤ This exercise can therefore be tricky: this is why it is important to choose the right mediator in order to be well supported, not only to be understood by those around him, but also to carry out his mission. ➤ What to communicate? When ? Whose ? These questions will find an answer in the consistency of the actions undertaken. Good managerial communication will thus aim to exchange / dialogue effectively with its employees, maintain a close link between the different layers of the company, bring human relations back to the heart of the company, establish a climate of trust and good team cohesion, motivate by inspiring. ➤ In short, each session combines techniques & practice exercises adapted to your everyday situations (filmed with your agreement in order to be reviewed, commented on, decoded together live), so that you can put them into practice immediately, and this from the 1st session. Statistically, the progression following these private sessions is quickly noticeable, from 2 or 3 sessions *. (* study 2020). ➤ THE TRAINER: Trained in Grande Ecole post-preparatory classes & Ivy League university in the United States, our teacher has specialized and has been working for more than 15 years, in Europe and North America, in the field of communication , in reputable international public and private establishments, intervening in forums and conferences, and oriented on two axes: training and coaching, with pedagogy and careful methodology as key words. ➤ PLACE, TIMETABLE, PRICES - Locations: Geneva-Lausanne-Friborg-Zurich-Neuchâtel-Lugano-Montreux-Bâle-Neuchâtel-Berne-Lucerne-Bruxelles-Luxembourg-Paris-Lyon. But currently and until further notice, only by videoconference in accordance with national recommendations on Covid, this format also unanimously suitable for those accompanied. -Apart from the classic advantages of videoconferencing (time savings related to travel, eco-responsibility, increased scheduling flexibility, etc.), the quality of the session & the interaction remain the same. In addition, the notes taken during the sessions are immediately transcribed on the session chat and are automatically transmitted to you so that you can browse them during and after the session if you wish. - Hourly fees: To support each other and to be pleasant to you in this period of covid19 and in a spirit of solidarity, the fees have been temporarily reduced. But this fixed price will not increase after the start of the sessions. -Sessions in English / French -As other people do regularly, you can also please your loved ones by offering gift vouchers available all year round. -Program: adapted to each need
