I used to write some scripts in PHP which i was going to run on Linux. Unfortunately, I was faced with this small error :

Bad interpreter: No such file or directory

All you need to fix it is just run this command :

dos2unix /path/to/your/script.php

I used to find many times duplicates in my table in MySQL database this time. First of all, I will paste here my table structure below (yes i know that it is difficult to read) :

mysql> describe proxy_parser_statistics;
+-----------------------+---------+------+-----+---------+----------------+
| Field                 | Type    | Null | Key | Default | Extra          |
+-----------------------+---------+------+-----+---------+----------------+
| ID                    | int(11) | NO   | PRI | NULL    | auto_increment |
| file_name             | text    | NO   |     | NULL    |                |
| processing_stamp_date | date    | YES  |     | NULL    |                |
| processing_stamp_time | time    | YES  |     | NULL    |                |
| processed_records     | int(11) | YES  |     | NULL    |                |
+-----------------------+---------+------+-----+---------+----------------+

I just use this query :

SELECT a.id, a.file_name FROM proxy_parser_statistics a INNER JOIN proxy_parser_statistics b ON a.file_name = b.file_name WHERE a.id <> b.id

Hi, I would like to show you very quick and I hope so, quite useful advice, how to run some job in every hour using crontab :

In recent time Institute of Communications (Instytut Łączności) began work on create a common API for telecom operators in Poland such a Orange, Plus, T-Mobile and Play to unificate using of their network functionality for instance sending and receiving SMS/MMS/USSD, make phone calls, phone localization etc.

I think that this work of Institute of Communications and major telecoms in Poland, will help developers and small companies to reduce costs associated with the need to adopt their services to telecom networks in Poland.
