We host several competitions through the year to try and produce results for continuing students. These events should also be viewed as a way to attract and work with potential new students. In particular, Math Kangaroo and our Russian School Olympiad are great events to open to all students (whether currently enrolled or not). Principals should advertise them locally, prepare marketing materials for interested parents who show up and make themselves available to answer questions before and after testing. In some branches they even offer a presentation about our program to parents while the kids are engaged in the competitions. These tactics seem especially useful in newer markets as a means of advertising our brand among competition-oriented families. In established markets, most of the families who come already know about us- we just aren't the right fit for them so there is a lower rate of conversion on families. To this end, some existing branches have even considered restricting non-RSM students from participating.
Мы всегда мечтали сделать iPhone одним большим дисплеем. Настолько впечатляющим дисплеем, чтобы вы забывали о самом физическом устройстве. И настолько умным устройством, чтобы оно реагировало на прикосновение, слово и даже взгляд. iPhone X воплощает мечту в реальность.
Это смартфон будущего.
Justice Jackson described his fear of what happens when the ends of government become remote from the wishes of the people due to the meddling of the bar and its assertions of fake complexity. “When free government becomes too perplexing and futile,” he said, “the people turn to dictatorship. It is the simplest form of government.”
Turns out, if you add point A a lot of times (in other words, multiply it by a large enough number) and get another point B, it will be hard to figure out what that number was, provided you are given only the original point A and the resulting point B.
My strategy in the post is to build Bitcoin up in stages. I’ll begin by explaining a very simple digital currency, based on ideas that are almost obvious. We’ll call that currency Infocoin, to distinguish it from Bitcoin. Of course, our first version of Infocoin will have many deficiencies, and so we’ll go through several iterations of Infocoin, with each iteration introducing just one or two simple new ideas. After several such iterations, we’ll arrive at the full Bitcoin protocol. We will have reinvented Bitcoin!
A blockchain – originally block chain – is a distributed database that is used to maintain a continuously growing list of records, called blocks. Each block contains a timestamp and a link to a previous block. A blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. By design, blockchains are inherently resistant to modification of the data. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks and the collusion of the network. Functionally, a blockchain can serve as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The ledger itself can also be programmed to trigger transactions automatically.
