find the right information online is not so simple. It would seem that the search services have been indexed and have learned to quickly detect emerging sites. You can search not only web pages, but video, audio, etc. (how, is another question). For the most patient of people with an analytical mind came up with enhanced query for searching. (I personally rarely use them, but perhaps someone already is not without them, his life). The calculation formula of the ratings of the relevance of results will save us a lot of time browsing the information. Still, for example, there are services that you can sing into the phone song, and they'll say, what was the song and give a listen to the original. Incidentally, the service is innovative. This is one of the few examples where a search is not a text phrase, and directly in the digital "content". Very funny, try it, if your company will pay you the account for telephone calls. By the way, try to find this service, for exampl

Hello, colleagues! Finally, we can say with a clear conscience to inform you that the next, third, the conference of the Ural web developers will be held on 25th and 26th of February in Chelyabinsk , and there will be a lot of interest. / > Very briefly about the event UWDC (Ural Web Developer Conference) is an annual event held in Chelyabinsk, they are web developers, designers and other Ionici from all over the Urals, Russia and even some from abroad. This year we're looking at about 50 speakers and 500 participants generally. The conference UWDC is an informal and friendly atmosphere, interesting content and positive emotions. most interesting Below I will discuss the most interesting, in my subjective opinion, reports and sections. Maybe you will be interested in something else — see the provisional programme on the conference website . In the section Alexander Makarov , a leading developer of Yii, will talk about the history of the development and

This service was created in the first place because they were necessary to me. Since 2002 I have been in the web development with the involvement of freelancers. After some time I got permanent staff and freelancers. First, the discussion of the projects and work on them was carried out by voice, telephone and email. to Skip the background and go to the control panel Phone voice and Skype : this type of control has certain advantages in that you can use eloquence, comlimenti and reprimands. But practice shows that if the freelancer is chosen, then all this is useless. But if successful, it is possible to go without calls. However, when you voice a number of disadvantages: often forgotten what was said. To record calls, which is hard and more harder then these entries to find what and when was said. Problem with “forgot”, “it was said”, ” I knew not” – huge. In the project where many details can not be put into such a control method. mail - during the executio

perspective... Back in the issue of content monetization on Habrahabr and the use of different models of this process read the opinions of our colleagues... Sergey Rudnev, a specialist in advertising and pr in the Internet, believes that social networking "is what the advertiser is a clear audience, loyal to the project (and thus, loyal to your products) and conducting on site for a considerable time". the he Also believes that many well-known social Internet projects for example, Habrahabr, will be able to significantly capitalized in the future: " don't want to say that ... resource is aimed only at profit with the help of free of "content cows" , but, for example, the fact that your account cannot be deleted (at least, at that time, when I was trying to do), says that the number of registered users (and possibly all user data) will be featured in the commercial proposal for the investor/advertiser. I hope it will not be so. Bec

I'm studying for a bachelor's degree in the Odessa legal Academy and as I remember myself in this role — I really miss the electronic legal aid in my pocket. Not like in ' 82 in the yard, and to carry a pair of 3-4 knizhentsii was my duty. Habr were full of news about the next updates of the iOS/Android versions pravo.ru and the toad to the Russian colleagues, I was incredibly crushed. But it has happened, and there was square national product framework ipLex, which, in fact, I want to tell as release candidates a tester. How many times to you on the street, far-fetched article clung Ppsniki, %username%? How many the tax you did not give a hard fight back, deftly wielding the quotes from the legislation? And whether you're under pressure from dishonest employees to quote the Constitution and other laws, do you know your rights and freedoms? Ashamed? Take the smart in the hands and let's a cat!

Finally launched for public beta test of the original search engine Blekko developed under the leadership of Richard Skrenta (Rich Skrenta). Richard Skrenta gained notoriety in hacker circles in 1982, when he wrote virus Elk Cloner , considered the first mass virus for personal computers (back then it was Apple II). The talented player was only 15 years old, he went to school. In the late 80s and 90s Skrenta worked in companies Amiga Unix (Commodore Business Machines), Unix System Labs and Sun Microsystems (developed encryption at IP level). Later he was one of the founders of the open directory Open Directory Project , bought soon by Netscape. Then he resigned and founded the news aggregator Topix , which, in 2005, also successfully sold one of the American publishing consortium. Search engine Blekko — his new startup, created with the assistance of investment capital former colleague Marc Andreessen (author of the Mosaic browser and cofounder of Netscape). In Gener

Today, 10 September 2012, was officially released the release of PostgreSQL 9.2! / > Finally ended a long period of beta testing, announced in may this year. The developers promise even greater performance, scalability and flexibility (performance, scalability and flexibility). performance and scalability Postgres now supports the 64-core processors, and lowered his Postgres'a, power consumption. Then I suspect everything is clear and without superfluous retreats. The mechanism of index-only scan . That for an animal such? The fact that the indices in the Postgres database does not provide information about visibility of record. That is, to understand visible to any entry, the server must read the real table the tuple (tuple). There are times that the index contains information about obsolete tuple. It is clear and the horse that access sorted index for much faster access to real table, which can be smeared somehow. Briefly, in version 9.2 this feint ears ar

To be clear, what was going on, I must say that our service is the exchange of copywriting ContentMonster.ru . At the moment, it runs more than 300 orders a day and is constantly working more than 400 authors. We are working on its creation is already more than six years, and during that time has filled a number of "bumps", most of which could have been avoided. Most likely, if the mistakes were not, we would grow faster, users would be greater and more stable psyche. So, let's begin. 1. Run update on Friday. To ensure that the project is pleased with their constant growth, need over him to work tirelessly. Users waiting for new features, please do the necessary for them features, implying that a little more and they will be offended and leave to the competitors. We continuously recorded the user's wishes in a separate list, doing the most urgent at the moment, the tasks and fill the updates on a production server. It was found experimentally that

to the Attention of all progressive nerds and fans to look to the future! Tomorrow at 16:00 at MSU will host a seminar on the problems and future of computer networking workshop is supported by the Center for applied research of computer networks SKOLKOVO — this is a unique opportunity to communicate directly with the developers of the Protocol OpenFlow and to learn how to build Vychislitelnye network in 5-10 years. in short, OpenFlow is to try to design network protocols with a clean slate, but given the 40 years of existence of the networks and directly under modern conditions with an avalanche of traffic. The OpenFlow switch is implemented only on the level of data transfer. The car's controller is much more simple device, whose task is to take incoming frame, extract from it the address and if the destination is in the table of switching, the immediate transfer of the frame and switching matrix. Otherwise, the switch over a secure channel sends a request to

Google has received another lawsuit (I wonder how many of these lawsuits filed against corporations?) from a small Irish hotel. The hotel is really not the big and famous, but the administration was unpleasantly surprised when I noticed that when you enter the hotel name in the search box, it displays a few search suggestions, one of which shows the word "receivership" next to the name of the hotel. This word is difficult to translate into Russian, but the term literally means "management of a bankrupt's estate". That is a potential customer, entering the name of the hotel, could see the word and decide that the hotel was bankrupt. It is clear that in this hotel no one will go. Now the owner of the hotel (its name — Ballymascanlon House Hotel, Golf and Leisure Club) filed a lawsuit against the Corporation, asking to remove that term from the search suggestions in respect of the institution. In General, for corporations not the first to be in a

to work in a new project uses PostgreSQL. Because so far I have worked with MySQL, now have to study and discover Postgre. The first challenge that interested me was the replacement muskulistogo SQL_CALC_FOUND_ROWS . When you use this constant in MySQL, you can obtain the number of all the query finds entries even if the query limit'ω is indispensable in a paged output of search results when using "heavy" queries. Immediately ready-made solutions could not be found. The forums just stated that the SQL_CALC_FOUND_ROWS in Postgre no. Some wrote that it is necessary to use count(*). And no more information. But also from MySQL I know that the search with a count () query is running almost 2 times slower than with SQL_CALC_FOUND_ROWS. I consulted those who use PostgreSQL, a day plagued google and the result received 4 replacement option SQL_CALC_FOUND_ROWS in PostgreSQL, one of which is quite comprehensible speed. So, just imagine those four options, which will be d

Without a database, even without a few radically different, such a project is impossible. So we will devote time to this question. So at least will need a database serving the usual "flat" (2D) data – i.e., a certain ID is assigned to the data field. Why is the field data I consider one? Because: the selection is based only on the ID field of the search data is not possible. There is a specialized index – otherwise such amounts of information will be of little avail the any number of fields can be Packed into one, for this I "on the knee" has created a small set of application libraries, in particular when the package is stored CRC data, not to use God forbid broken If you do not set a task of minimizing the number of lines of code working with data and a bit of convenience, almost any task can be reduced to one where these items will be sufficient. In the case of such high requirements of optimality and speed, in my opinion it is justified. Th

In may 2011, Google launched search flights in the hint text when the search request (works on the Russian language for local routes). It was clear that the company is seriously working in this direction and soon travel agents will have to find a new job 1 . And continued not long in coming. Yesterday opened a full search of tickets normal interface Google Flights . He is restricted to the territory of the United States. Search, display of prices and plotting works extremely quickly, even when you specify up to five places of departure and five arrival dnom search request that makes you wonder how it is implemented. Friendly graphical interface shows schedule of flights between the selected points, the ticket price of every airline on the specified date, time of flight. Use the individual sliders, you can filter the results by time of flight (there and back) and the cost of the ticket. The calendar shows what days the tickets will be cheaper.

Surprisingly, this event left unattended on habré. I hasten to correct the situation. 12 APR Crytek and Mail.Ru Group announced the launch of open beta testing of its new online shooter called Warface. It is noteworthy that Russian players are the first in the world had a unique opportunity to try yourself on the battlefield Warface. Warface is an online multiplayer shooter that will be distributed on the model Free2Play . Under the cut is a small squeeze of information about the game and the developers. If you are interested in more information, then it is better to go for the official website of Warface in Russia . And even better download game to see. Free2Play All the main game content in Warface is free, but those who this be not enough, can use real money to purchase additional items such as more badass weapons, gear and various equipment. All of the above can be purchased for in-game points. There are three types of currency: the the war bucks — ear

You have come a long and difficult path from idea to realization of your project. The stage of closed testing is completed and you are ready to present your creation to the world. The main and for some time the only advertising medium that your project can be a promotional video. It can be spread on YouTube and social networks, to send to partners and investors, to place on the home page, to accompany a press release to the media or to spice up a speech at the conference. The purpose of a promotional video briefly and clearly tell about the essence and value of the project to interest your target audience and motivate to become a user. How to make a good movie, which will manage until the end? How to make a movie called smile, an interest, a desire to see the project up close? There are no universal recipes, but there are proven plot scheme and rake, which have already occurred many times. In this article I will do a small review of promo videos for startups, which

Not so much expression there is in the SQL dialect of the Postgres database 'but that requires as argument a filesystem path. I can name a couple: the the CREATE TABLESPACE... the CREATE FUNCTION... (in case of dynamic loading of C functions) So, the crux of the matter is that these arguments are string constants. And this, in turn, means no lexical check, which leads to different effects in different operating systems. In order not to spread the idea of the tree: the Windows Users! Replace your usual slashes (backslash's, actually) these slashes: '/', parameters specifying the system path! the NO: CREATE TABLESPACE dbspace LOCATION 'C:\Program Files\PostgreSQL\8.3\data\dbs' ; CREATE TABLESPACE dbspace LOCATION E'C:\Program Files\PostgreSQL\8.3\data\dbs' ; * This source code was highlighted with Source Code Highlighter . the YES: CREATE TABLESPACE dbspace LOCATION 'C:/Program Files/Pos

If you sell an online service, you probably would like to see what is happening at each stage of the sales funnel. From the analysis of the funnel one can draw important conclusions: how clear and easy the process of installation and initial application settings, how many and which clients become active users of the service, what percentage goes from free version to the paid. In addition, the dynamics of conversion rates you can make a conclusion about the effectiveness of measures to increase sales. Under the cut you will find a description of some techniques for working with Excel, which can be useful in the analysis of data arrays. We will explain how we conduct managerial statistics service jivosite.ru using Excel's pivot table and connect to MySQL via ODBC on the example of report on sales funnel. The proposed method is quite simple and universal, it can be used to create beautiful reports in minutes. problem Statement You want to build a report on sales funne
