iPhone sucks!!
The problem is iPhone still thinks the handsfree is plugged in so it turns off the speaker.
My iPhone has got this issue as well. I fixed by keep plugging and unplugging until it worked.
That probably got the dust out from the jack.
If that does not fix, let’s try..
You could probably use alcohol to do this as well.

Somebody just got a new macbook and he wanted to run something every time it is turned on.
To create a startup script on OSX is not hard. Just a few steps.
Firstly, make a folder in /Library/StartupItems. Then create a plist file and an executable file. That’s it.
Let’s start with open Teminal and..
$ cd /Library/StartupItems $ sudo mkdir WhatEverNameYouWant $ cd WhatEverNameYouWant
and then create a file named StartupParameters.plist.
You can use whatever text editor to create and add..
{
Description = "WhatEverNameYouWant";
Provides = ("ScriptNameYouWant");
OrderPreference = "None";
}Next, create ScriptNameYouWant and put the commands you want.
Don’t forget to start the file with shebang #!/bin/sh to execute with Bourne shell.
This can be other. It depends on what you will execute.
The file will look like..
#!/bin/sh The commands to execute commands and the last command
Save and make it executable..
sudo chmod +x ScriptNameYouWant
and restart your mac. See what you fuckup your Mac lol
I’ve done Ruby on Rails with MySQL but never done done Ruby with MySQL. I just did this last week to check a small thing. I didn’t want to establish the whole Rails’s process. I takes a lot of memory.
Let’s do a quick start.
Install a driver first. You can get one that’s written by C or Ruby. If you got gem then that’s easy.
$ sudo gem install mysql
It’s written by C
It’s quite easy to start. Require ‘mysql’ then create a connection to the database and then query. If install by gem, just require ‘rubygems’ first.
require 'rubygems' require 'mysql' db = Mysql::new("host", "user", "passwd", "db") res = db.query("select * from mytable") res.each do |row| puts "id: #{row[0]}" end
and this is what I got
id: 1 id: 2 id: 3 id: 4 ... ...
Looks simple. The index of an element in an array is sorted by the sequence of columns in the table.
Or you can get the column names instead of the indexes by each_hash
res.each_hash do |row| puts "id: #{row['id']}" end
More information at the pages of the driver.
I’ve got it working but didn’t know how it works.
To avoid the same origin policy, JSON is a good thing to help you. The thing on the same origin policy is the browser requests from JavaScript or Flash aren’t allowed because we need to protect from script injection attacks. If this happens, the resources like http cookies will be accessed then your authentication or password in the cookies can be stolen.
So we can’t fix this but we can avoid it. The basic idea is we can request any Javascript anywhere.
<script src="http://somewhere/jsfile" type="text/javascript"></script>
Once it loaded, the browser could execute this javascript.
But if it receives json then it does nothing. We can make a returned Javascritpt looks like this.
var json_var = {'var1':'val1'};
It would be better if we can define the callback function.
myCallback({'var1':'val1'});
The server needs to provide this padding. The next thing is we have to declare this function(myCallback) to be executed once it loaded.
For instance, Graph on Facebook allows us to define the callback
https://graph.facebook.com/175459332480559/albums?callback=myCallback
by putting the ?callback=yourCallback at the end of uri
I misunderstood when I started because I saw the doc from jQuery that can put the dataType as jsonp and I thought it was just another asynchronous request which can request across the domain name on the browser.
Basically, jQuery actually provides the callback function as well like
https://graph.facebook.com/19292868552?callback=jsonp1291493679672
jsonp1291493679672 is the callback function to be defined in window like window['jsonp1291493679672'] which defines data and returns this data to the callback function we put in the ajax request. What it does is, jQuery puts ?callback=? at the end of uri and replaces a question mark(?) with jsonp1291493679672. The numbers at the end comes from now() btw.
