Thanks to Remy Sharp and his work on nodemon!

To get going install nodemon like so.


npm install -g nodemon


Then you can start your app like so.


nodemon app.js


Boom, you never have to worry about restarting nodejs, just code and GSD! (Get Sh*t Done)

I am heart broken and sad to hear that Steve Jobs has passed away. I truly believed he was a visionary and creative genius. One of my personal heroes and he will always be missed. Through him I knew that thinking differently was not the wrong path. This has led me to pursue my dreams and become an entrepreneur. Think different!

I want to start blogging about the challenges I have faced and how I solved them. Also would like to start talking about the new programming language I have started to pick up. Haskell! This is one tough language, requires me to think in a way I have never done before, but I am hoping to become a better developer from this!

var string_to_number = "10" * "10"; // result 100

I thought that was cool, but funky right? Note, this does not work with the “+” operator. So a cool way to convert a string into a number is to do the following cool trick:

var string_to_number = "200" - 0; // result 200 booyah!

That is it for this tip and trick. Let me know if you come across a neat tip.

var hello = "hel" + "lo"

This is not the interesting point I wanted to talk about. It actually gets more interesting on what happens when you concat
string literals with numbers. For example:

var x = "33" + 3 // result "333"

Notice the above example the number 3 was concatted with the string “33″ that result in the string “333″.
However can you guess what would happen if the number came first? More importantly what happens in this next example:

var x = 3 + 3 + "33" // result "633"

This is entirely different if you had done the values in a different order, for example:

var x = "33" + 3 + 3; //result "3333"

So be careful with this gotcha.

I must have been under a rock for the last couple of years, because JavaScript has really become super popular and I have just been ignoring it like that stupid American Idol show everyone in America seems to love.

Anyways, I am finally doing a full 360 and relearning JavaScript as an effort to enhance my web development skills.

/opt/local/bin/

I ended getting a big error report which said something along the lines of:

mkdir: /opt/local/var/run: No such file or directory
chown: /opt/local/var/run/mysql5: No such file or directory
chmod: /opt/local/var/run/mysql5: No such file or directory

Solution
I solved this by doing the following:

1. Make sure you have ran the following command after the install completes:

   sudo /opt/local/lib/mysql5/bin/mysql_install_db  --user=mysql
   

2. Finally you have to do the following:

   sudo mkdir /opt/local/var/run
   sudo chmod g+w /opt/local/var/run/
   sudo mkdir /opt/local/var/run/mysql5
   sudo chown mysql /opt/local/var/run/mysql5/
   

Now you should be able to start mysql with no problems! A little bonus is create alias for starting and stopping mysql. My MBP is running Snow Leopard so I edit:

 ~/.profile 

and add the following at the end of the file:

alias mysqlstart='sudo /opt/local/bin/mysqld_safe5 &'
alias mysqlstop='/opt/local/bin/mysqladmin5 -u root -p shutdown'
