From the incubator Y Combinator was another interesting startup: personal search engine Greplin . The idea is to index all personal information that you provide to social services: Facebook, Twitter, Dropbox, Evernote, LinkedIn, Gmail, Google Docs, Google Calendar, Google Voice, etc. — and then provide the search according to your personal archive. The system works very simply: specify the passwords for the services (use secure authentication OAuth and other APIs, so that system cannot see your password) — and after a few minutes of indexing you get for personal use ascetic search line in Google style. It is a familiar idea for those who had used a desktop search engine that indexes all documents on the hard disk, including e-mail, IM logs and other personal information. Same here, but only online, because now, more personal information is stored online, not on your home PC. If a man is, so to say, rapid online life, often he doesn't remember what exactly the serv

the Backstory After the appearance of a topic about the app for Android OS that allows you to monitor the work of public transport of Saint-Petersburg, I came up with the idea to create a convenient and versatile method of access to this information as possible with more devices. The idea to create an app for each platform dropped immediately — it will take a lot of time and I have no way to test their programs on all those devices. Therefore, it was selected a web application running in the browser. This opens up the possibility of its operation in most mobile OS that has a browser with JavaScript support. Thus, we get a rather big list: Android, iPhone, iPad and other iOS devices, Maemo, Windows phone 7, webOS, MeeGo, Moblin... and so on (in theory). Still remain a regular, non-touch phones, which are usually used OperaMini. It will try to adapt the interface of the same application. The result is this: spbtransport.ru The Android app SPB Transport UPD 1. some time a

It turns out that the user requests may very well be correlated with, for example, the speed of the spread of influenza. That is, the frequency of requests associated with the same flu, can match with the speed of growth in the number of diseases flu. If such a correlation is to display on the graph, there is almost complete coincidence. This was spotted somewhere in the end of 2008, when Google launched the service Google Flu Trends . The service tracked the number of user requests associated with the flu, and compared such data with the speed of the spread of the disease. It turned out that on the basis of these data it is possible to predict the probability of occurrence of the beginning of a flu epidemic in a particular region or even to predict the development of epidemics, and for quite a long time. of Course, scientists of different areas are interested in this service, and developers corporations few years presented new service , which allows to track dependencies

Recently, I had an interesting challenge in storing some data in the session work with the database PostgreSQL (TTL = life time of a single connection to the database). The original question was... Is it possible that instead of this design: the some_procedure1(user_id, param1, ... , paramN); ... some_procedureX(user_id, param1, ... , paramN); use this: the set_user(id); some_procedure1(param1, ... , paramN); .... some_procedureX(param1, ... , paramN); i.e. to use some kind of global variable within the session to store the user ID value, which will be available to all procedures in the database. Digging on Google, asked around on the forum, I found not even one solution, and as many as 3! Than with you and share... the First option. Using a temporary table. As stated in documentation , quote: PostgreSQL instead requires each session to issue its own CREATE TEMPORARY TABLE command for each temporary table to be used. for each session we need to re-create the
