#Rails Logger Tricks

#Here are a few quick tricks for using the Rails logger.

#Save disk space by rotating logs in the config/environments/test.rb and config/environments/development.rb

config.logger = Logger.new(Rails.root.join("log",Rails.env + ".log"),3,5*1024*1024)
#which will rotate the log files every 5 megabytes and leave only the three most recent log files. This will limit the total spaces #used by the logs at 15 megabytes.

#To log to STDOUT while using the console use this trick:

exporting your repository

Previously there was a tip that covered sharing changes but that included all of your repository’s history.
What if you just want to export a certain commit’s changes? Or just one folder? What if you wanted to make 
an archive of the repository for backup? 

Fear not, for Git can do all that and more. Thanks to Stack Overflow for providing with some helpful hints to add into this post.
If your need is to just make a quick backup of your repository, doing a git archive will help. So if you wanted to get 
zip file packed with your repository’s files:

Creating fancy money entry for your Rails app

This week I was working on a client project where we wanted to implement a nice way of entering an amount of money. We wanted to replace a standard text input field with something like this:

Money entry sample

In the resulting implementation, when the user types the amount in the text box it automatically splits thousands and the decimal point.

Asynchronous and deferred JavaScript execution explained

The HTML <script> element allows you to define when the JavaScript code in your page should start executing. The “async” and “defer” attributes were added to WebKit early September. Firefox has been supporting them quite a while already. Does your browser support the attributes?



Normal execution <script>
-------------------------------
This is the default behavior of the <script> element. Parsing of the HTML code pauses while the script is executing. For slow servers and heavy scripts this means that displaying the webpage will be delayed.

If you get following error, when you try to start nginx…

[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

Then it means nginx or some other process is already using port 80.

You can kill it using:

sudo fuser -k 80/tcp

Import a large sql dump file to a MySQL database from command line
Posted on March 19, 2013 by cmanios
Today I had to import a very large SQL dump file (6 Gb) to a MySQL database using windows command line. If you are using linux it is the same. The process is the following:

Open a command prompt (or shell in Linux) with administrative privilleges
If you are in Windows set character set to unicode. Linux is using UTF-8 by default.
chcp 65001
Connect to a mysql instance using command line
$PATH_TO_MYSQL\mysql.exe -h 192.168.1.1 --port=3306 -u root -p
if you are in localhost you do not need host and port
