Shows CLI diff between two plist files
#!/bin/bash
## @file
## Shows CLI diff between two plist files.
##
## Normally, Mac plist files are binary, so diffs do not display. However,
## there are cases where seeing diffs is important. For example, when tracking
## changes via Mackup's git storage option.
##
## Note this option allows seeing plist diffs without fully installing Xcode

How to Build a Fast Limit Order Book

https://web.archive.org/web/20110219163448/http://howtohft.wordpress.com/2011/02/15/how-to-build-a-fast-limit-order-book/

The response to my first few posts has been much larger than I’d imagined and I’d like to thank everyone for the encouragement.

If you’re interested in building a trading system I recommend first reading my previous post on general ideas to keep in mind.

My first really technical post will be on how to build a limit order book, probably the single most important component of a trading system. Because the data structure chosen to represent the limit order book will be the primary source of market information for trading models, it is important to make it both absolutely correct and extremely fast.

To give some idea of the data volumes, the Nasdaq TotalView ITCH feed, which is every event in every instrument traded on the Nasdaq, can have data rates of 20+ gigabytes/day with spikes of 3 megabytes/second or more. The individual messages average about 20 bytes each so this means handling

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.) 
    

    2. 



git clone --bare git@github.com:usi-systems/easytrace.git

Язык запросов Яндекса


Морфология и поисковый контекст


При поиске с учетом морфологии принимаются во внимание:


    

  • форма заданного слова (падеж, род, число, склонение и т. д.);
    • 

  • часть речи (существительное, прилагательное, глагол и т. д.).
    • 



По умолчанию Яндекс ищет все формы слова, указанного в запросе. Например, при запросе [рассказал] поиск будет производиться по глагольным формам: «рассказать», «расскажу», «рассказывать» и т. д., но не по однокоренным словам типа «рассказ», «рассказчик». Исключение составляют случаи, когда используются операторы ! и " .
