Руссифицируем Sphider 1.3.6 или Sphider vs UTF-8

Доброго времени суток, уважаемые читатели моего блога! Столкнулся с Sphiderом в учебных целях, и обнаружил, что мой сайт ( не индексируется этим роботом! Выдает ошибки в SQL запросах и все тут!

Логирование запросов SQL в Denwer 3 с MySQL 5

И добавим в него строку: define('WP_POST_REVISIONS', false); Перед выполнением работ с базой сделаем дамп базы на [] read more »

Moving My Own Little Mountain

Last year, I returned to a question that has been bugging me for a number of years with Toronto's weather. The problem was that in order to find the answer, I needed some data - and whilst the data is freely available to answer the question, it's just not in a form that I could easily query.

So, back in the winter, I wrote a program for the RaspberryPi (http:/... read more »
