New tvitnut buttons or farewell counter

1 year, 9 months ago
On November 20 Twitter disconnected a possibility of viewing of the counter of links through private API of the buttons and removed the counter from their official design what they warned in the blog a little more than a month ago about. New buttons look so now:

It is about API located at the address: http://cdn.api.twitter.com/1/urls/count.json. Earlier, having transferred the necessary url, it was possible to receive number of tweets/retweets in which the reference to this url is contained. From now on instead of usual json, API returns an error 404.

API though officially also was private, but upon, was not limited in use in any way and for years of its existence managed to form the basis of a set of the services which are engaged in this or that data analysis.

Officially Twitter connects it with complexity of transfer of functionality on a new platform, to be exact, on low priority of this task, concerning others and convince the users that the counter on the button does not play any special role for visitors of the websites. However, it is the first case of failure of a large social network from the counter on the button.

2 years, 4 months ago


IBM и Twitter представили первые в отрасли облачные сервисы, которые позволяют бизнес-профессионалам и разработчикам извлекать ценную информацию из данных Twitter. В процессе реализации проекта IBM и Twitter тесно сотрудничали с более чем 100 клиентами, и уже сегодня предоставляют корпоративным заказчикам возможность применять социальные данные для принятия бизнес-решений.

2 years, 11 months ago
Due to the API twitter updatings from version 1.0 to version 1.1 requests not receiving RSS tape in old style, it seems have ceased to work:



It is connected with the end of support of twitter ohm of XML, RSS and Atom of standards of output. Developers have commented on their motives at acceptance of similar solution the thesis that the share of similar requests is small and can be disconnected without serious consequences for users.

But I am inclined to assume that there will be users who would like to see that functionality, nevertheless. For this group the narration below will also be led.

It already was in? Simpsonakh?


There is mass of solutions of this problem. Probably, the most adequate? this creation of widget in the account of the twitter with the subsequent transfer of data to google apps script for the subsequent forming of the RSS tape. This solution is described here.
But after all not all have the twitter account, and among who does not have it, there can quite be also those who wants to read others tweets simply.

Strictly speaking, the solution which I will propose below, is not absolutely reading someone's twitter, it simply search of all references of user name.
