Review of #dchh 2013 in Hamburg

Recently I visited the Developer Conference 2013 in Hamburg (developer-conference.eu), a German speaking conference about programmierung and web business initiated by Tarek Mueller (@TarekMueller) and Sebastian Betz who live inside the Hamburg startup scene.
The conference was held for the third time, this time in a much bigger environment. In opposite to the first two years with around 300 visitors in the OTTO building, this year the Cinemaxx was rented for around 1500 visitors.
Here I list a short summary of the talks I have visited attaching a small comment from me. I need to say sorry for the uncomfortable table format.

reset forgotten MySQL root password

There may be several reasons for the need to recover a MySQL root password. In my case, I changed it on my local developer machine a while ago and I did not remember the new password.

Resetting the password is very easy – if you have root access to your machine.

  1. Create a file containing:
    UPDATE `mysql`.`user` SET `Password`=PASSWORD('MyNewPass') WHERE `User`='root';
    FLUSH PRIVILEGES;
  2. Stop your MySQL-Server
  3. Start your MySQL-Server with the following command:
    mysqld_safe --init-file=/path/to/your/file

Now you should be able to log into your MySQL-Server using root and MyNewPass (I recommend you to not use THIS password, if your server is reachable in any way).

This post is a simplification of a part of the official reference manual here: MySQL Manual.

Using Xdebug with your IDE gives you a lot of benefits. While clicking through the browser you can directly follow the code (by setting breakpoints) inside your IDE. You can find an introduction in Xdebug here and the whole documentation, surprise surprise, on xdebug.org.

Integrate Redmine into PhpStorm/IntelliJ (on Mac OS X)

Integrating Redmine 1.3.2 into PhpStorm 3.0 (or probably other IntelliJ IDEs) has several benefits. I mainly use it to read the descriptions of my tasks directly inside PhpStorm.

What do you need?

  • Admin access to Redmine to enable the REST web service and to see the identifier of your project
  • for self-signed HTTPS certificates sudo/root access to a terminal (if your Redmine URL starts with https, you may need it)
