MSFT announced azure .) Will it scale? It's conventional wisdom that relational databases aren't as scalable as the schemaless entity-Attribute-value (EAV) tables used by SSDS, original SDS, Amazon simpledb, and Google's bigtable and the App Engine's data store. if the SSDS team was leveling with us when they attributed the choice of the Eav (authority-container-entity) data model to simplifying data access (not scalability ), it cocould turn out that conventional wisdom was wrong in this case.

In the previous article, I wrote how to enable scrapy to Support HTTP proxy. But scrapy does not support socks proxy by default. Sometimes the pure HTTP proxy is easily intercepted by g f w, and proxy is required to collect websites blocked from abroad. Okay, capability is forced by demand. The following describes a solution. Deploy a Linux VPs in the United States or Hong Kong Debian as an Example Install necessary components Apt-Get install build-

Describe Each query outputs a score of a A/b in a row indicating the probability of randomly extracting two socks of the same color from the range [l,r] of the query. Analysis Interval without modification of the topic, just require a variety of colors, so you can use Mo team. If the number of colors I in the interval [L, R] is c[i], then the probability of randomly extracting two

You can use Tor services with different Tor tools, such as Tor Browser, Foxyproxy, and other things, and download managers like wget and aria2 can't use Tor socks to start anonymous downloads, so we need some tools to get Tor socks Convert it to an HTTP proxy so that it can be downloaded.Note: This tutorial is based on Debian and the other distributions are somewhat different, so if your distribution is bas

The main topic: give some socks in the order, each time asked how many of the same color in the socks pair.Idea: Mo team algorithm is really a magic algorithm. First, the brute force enumeration is the time complexity of O (n^2), which is certainly not possible. If the interval is guaranteed not to overlap, then the total time transfer complexity can be reduced to O (n). Unfortunately, there is no such guar
