continuing the theme of queries, not addressed by search engines (or specifically the queries are filtered). Last time the focus was Bing, which is not quite successfully tried to block the bots, causing some client requests that do not have cookies Bing return an error . Now the "hole" found in Google: for example, this query [9999999..99999999999999999999999] is blocked by Google. Instead, the Niners may be other numbers. This is a specific request format X..Y, which includes all numbers from X to Y. the hypothesis that the range of numbers is too large and therefore the system can not cope with the request can be discarded. Small investigation showed that blocking such queries from Google, apparently due to suppression of the carders. In may 2011, a security expert from F-Secure Mikko Hypponen noticed , Google mobile search allows you to search for credit card numbers, indicating the appropriate range of numbers. Ten hours later such queries was blocked ....

According to the analytical Agency comScore, in December 2011, the search service from Microsoft took a larger share of the search market in the US than the search engine Yahoo. It happened for the first time, but for the most part the cause of the incident — the loss of the search market Yahoo. In December, Bing has added just 0.1% to a private share, but Yahoo lost 0.6%, which is a pretty significant loss. In any case, the Bing team can celebrate, because the share of this search service at least a little, but continues to grow. By the way, recently Bing has turned 3 years. It should be noted that the search service from Microsoft is a platform for running Yahoo search.

I often deal with tasks that require very large database performance while processing large amounts of data. Today I will talk about very simple but effective technique that can help you out if base has not kept pace with the amount of data that accumulates and needs to be treated. The method does not depend on the database, but the habit of publishing blog PostgreSQL, and a sample will be on it. Let's cut to the example. Spherical cow Suppose we are talking about simple billing (it is clear that the method is applicable not only for billing, but it will look quite clearly). A table that accumulates data about calls of subscribers will be in our case to have this format: CREATE TABLE billing.calls ( call_id BIGINT, call_time TIMESTAMP subscriber_id INTEGER duration INTERVAL ); * This source code was highlighted with Source Code Highlighter . Here so all simply. Data about calls form this sign with insane speed, and must be within a reasonable tim...

Hello. Considering that since the release of PostgreSQL 9 it's been some time — I decided to probe one of its new features — native replication. As you know, the new mechanism is based on transmitting a XLOG'from master to slave. One of the advantages of fatty can be called normal processing ALTER's. In other words — the administrator 9th version can do without Slony. We assume that the packages you have installed(and if not, for Debian/Ubuntu you can get them here ) has created a database testdb. I describe the process assuming that a base postgres'you are in /var/lib/postgresql/9.0/, if not — use the correct path for you. So there you go: 1. Custom listen && pg_hba.conf Suppose that the ip 192.168.0.1 we have a master and slave is 192.168.0.2. Then the string "listen" in postgresql.we have conf will look like this: listen_addresses = '192.168.0.1' And in pg_hba.conf on the master would be this entry: the host replica...
