Things seemed to be a bit streamlined and I was okay with the clean, simple interface.  My biggest challenge was inserting multiple rows.

Clicking on every menu, right-clicking on single rows,  or trying the traditional ctrl + did not do the trick.  It is a little cumbersome, but here is how I got around this annoyance:

This what Google gives you by default:

After all my cutting and pasting, I decided to highlight multiple rows, this did not work. What you need to do is highlight the row numbers (headers?) and not the actual rows.  Once they are highlighted, right-click on the row numbers column and you will see the menu change, like so:

Although this is a bit clunky, it did resolved my issue of adding one row at a time.  I really hope Google brings shortcut support to this little, yet important task.

I had a situation where I had to move a home directory (in-tact) from one user to another.  Permissions became very inconsistent since the previous user never fully migrated his profile from his predecessor.  To clean up the mess I did the following (works on Snow Leopard/Lion):

Enabled Root User
Go to your System Preferences and under system click on Accounts

Then click on Login Options, and to the right you will see Network Account Server, click Join.

A window will pop-up, continue by clicking on Open Directory Utility …

This will open the Directory Utility, make sure the small lock on the bottom left is in the Unlocked position, if not, click on it and enter your admin password. Once it is unlocked, go to the top menu, click Edit > Enable Root User

Once you Enable Root User, you will be prompted to enter a password for the Root.

Backup up both profiles
Now that Root is enabled, log in under a separate Admin account – Make sure you are not logged in as one of the users you are moving.

Add the new user to your system. (System Preferences > Accounts > +)

Once you have added the new user to your system, open up Terminal and become root by typing “su – root” without the quotes.
Once you are done, make a copy of both the new user and the old user profile directory e.g. /Users/NewUser/ and /Users/OldUser. Compare the newly created backups with the old directories to make sure the structure is the same.

Move the profile to the new user
Now that you have compared the directories, you are ready to move everything over to the new user. Remove the original (not the newly created backup) /Users/NewUser.

Now move the old user to the new user e.g. mv /Users/OldUser /Users/NewUser

Recursively change permissions
I had a minor issue with syntax, but after a little trial and error I did the following:

From /Users/ I typed chown -R NewUser *

This changes the permissions(ownership) from OldUser to NewUser.

Log in and Test your new permissions
Log out of the current profile and log in under NewUser and test the permission by opening up any documents or desktop elements.

Good Luck

I confirmed I had the latest iTunes, confirmed all OSx updates with no luck.  After looking around the web I found that the issue is related to a DNS entry in the host file.  To fix the issue and get around the loop, do the following:

• Open “Terminal”(/applications/utitlities/terminal.app)
• Type sudo vim /etc/hosts (you will be prompted to enter your password)
• Scroll down till you find gs.apple.com, now arrow to the beginning of that line (hit the “i” to insert a the following character) put a “#”  in front of it, the result should be simliar to #127.0.0.1 gs.apple.com, now hit the “esc” key.
• Now type :w and the enter key, followed by :q and the  enter key (this is writing the new hosts file, and quitting the editing program)
• To clear your cache type dscacheutil -flushcache

Good luck.

Recently I have been trying to wrap my head around a very annoying bug in Fireworks CS5.  The bug is noticeable when you are working on a document with two or more layers.

To see it in action you open a document and try to select a layer by left clicking your cursor on the layer. No matter how many times you try to click on the other layer, it won’t select it. (red outline)

After several attempts, I restarted Fireworks, but the problem persisted.  I also restarted my computer and continued to have the same problem.  Finally, I started closing all my applications and all of sudden I could select again.  So what was the problem? after closing all my apps I narrowed it down to Spotify.

Yes, running Spotify while you are working on Fireworks CS5 disables your ability to click on the layers within the canvas.  The only work around is to click on the layers via the layers panel or turn off Spotify.

Productivity disruption.

I am not sure when the engineers at Spotify will be able to resolve the problems, but I was able to find a support post on Get Satisfaction – you can also follow the latest on Adobe Forums.

I really hope this doesn’t mean its “back to iTunes” I have learned to love Spotify and I believe that once it hits the USA it will replace most if not all other music services.  We heart Spotify but can’t work with it on.  We will keep you posted.

Since Adium 1.3ish, we have noticed a bug that seems to be related to Facebook’s chat protocol.  After a bit of digging around we found that using the XMPP protocol fixes the captcha issue.

Below are a few simple steps  to setup Adium 1.4 to use the standard XMPP protocol with Facebook chat.

To use XMPP instead of the old implementation, do the following:

• Open Adium
• Add a “Jabber” account
• Type in your Facebook username* + @chat.facebook.com.
• Under Options, Set the connection server to “chat.facebook.com”

*To activate your username, go to Account, then Account Setting, and then Username

update confirmed on the Adium Wiki

When you started the computer it said that there was a font conflict and asked if it should ignore the conflict or move one of the files to the trash, well you should have moved it to the trash. Then just logged out and back in. That is it, empty the trash and you are completely done.

If you are having trouble with things like SIMBL and it’s plugins that is a different story, but as a hint: For now SIMBL stuff still works if you run the target application it in 32-Bit mode. Click the *.app file and then press Apple-I to bring up the info box where you can select 32-Bit only.

One last bit of advice is to ensure you upgrade programs like Little Snitch before you run your Snow Leopard Upgrade because it will not run without the upgrade and you will be left without a firewall until you upgrade, so might as well do it before and have it the whole time, or at least do it almost right away when you restart after the upgrade.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x=independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.

We are excited to be a part of Asheville’s very own independant TED event, TEDxAsheville.  Tonight at 7pm, people will come from all over the region to listen to some of Asheville’s most influentional speakers and performers.  Tonight’s Line-up includes:

2009 TEDxAsheville Speaker Lineup:

Dee Eggers
UNC Asheville professor of environmental studies

Drew  Jones
Climate scientist, the Sustainability Institute

David McConville
Media artist, the Elumenati

Caroline Yongue

and begin to turn this into my node types by just making a few adjustments to the list, really not even adjustments just classifications. Now here is that list after classifying them

• Pages

  • Sponsor URL – Textfield – Limit 128
  • Sponsor Banner Image – Textfield – Limit 64
  • Sponsor Priority – Dropdown – 0-10

Now for Drupal we have a pretty nice little list to just create in CCK by naming them applying these limits to the fields. This is pretty easy and if you ask your client to classify a certain area of their site like sponsors many times they will give you a list must like the first one. Using CCK this is all easy and once you are done you have a nice form, automatically built, that will only ask the administrator for the information that is needed and will create the node for them, it is straight forward, looks like all the other Drupal admin forms and handles validation for you.

So when I try other CMSs like modX, Concrete5, Joomla, etc… I always wonder as soon I install it how i go about doing the same thing within their system. Well the truth is that most CMS have something similar to Drupal’s CCK and to tell the truth again it is usually hard to find documentation on it because every calls it something different. There are content types, page types, and many many more names for the same thing. I prefer the term page type, because i think that it universally makes sense.

Creating this same thing in Silverstripe is actually really simple, it makes sense, and to me it is better than Drupal’s system because it is more flexible and since you are building basically a model and controller for your page type that extends the base Page model and controller then you have all the functionality of the Page but can also extend it as far as you want.

So lets get started with this same process just using Silverstripe! Lets take our blank list and classify it for Silverstripe.

• Pages
  • Already Created at Install
• Sponsors
  • Sponsor Name – Textfield – Varchar(128)
  • Sponsor URL – Textfield – Varchar(128)
  • Sponsor Banner Image – File Upload
  • Sponsor Priority – Dropdown from 0-10 – Integer(2)
• Classes
  • Class Name – Textfield – Varchar(64)
  • Class Description – Textarea – Text
  • Class Instructor – Textfield – Varchar(64)
  • Class Capacity – Textfield – Integer(3)
  • Class Slots Filled – Textfield – Integer(3)

Notice that the classifications of these fields more closely models a database, this is because Silverstripe is smart and they know that you are going to build these extensions with Models, so they should model a data source more closely. Let Take our list and get started with creating our page types now!

Lets start by creating a new file for our site. Open up the installation of Silverstripe and open up the folder mysite/code Next we want to create a file to extend the Page Model and Controller. Following Silverstipe conventions we will append the word “page” at the end of the file name, since we are extending Page. Lets do Classes as our example for simplicity. So lets add a file to our mysite/code folder and name it ClassPage.php With Silverstripe extending things is a lot like working with an MVC framework such as CakePHP or Code Igniter so we chose to name that ClassPage.php after the singular version of what our Model will represent. If we had been doing the Sponsors instead we would of named it SponsorPage.php

Now that we have our file, lets open it and start editing our code! Once we open the file we are going to want to let the system know what we have by declaring our Model class first. So lets do the following:

		class ClassPage extends Page
		{
			static $db = array();
 
			function getCMSFields()
			{
				return $fields;
			}
		}

Basically we have just declared our Model and told the system the name. Next we need to add more code to this declaration and make it actually add our database fields and connect them to this model. We also need to write the getCMSFields function, as it is a Silverstripe standard that will be called for your Model once someone creates a new instance of this page type. So lets get that out of the way and create our class variable db, another Silverstripe standard. This will ensure that when someone runs a db update that our fields will be installed into the DB. So lets change that previous code to this:

		class ClassPage extends Page
		{
			static $db = array(
				'ClassInstructor' => Varchar(64),
				'ClassCapacity' => Int(3),
				'ClassSlotsFilled' => Int(3)
			);
 
			function getCMSFields()
			{
				$fields = parent::getCMSFields();
				$fields->addFieldToTab('Root.Content.ClassInfo', new TextField('ClassInstructor'));
				$fields->addFieldToTab('Root.Content.ClassInfo', new TextField('ClassCapacity'));
				$fields->addFieldToTab('Root.Content.ClassInfo', new TextField('ClassSlotsFilled'));
				return $fields;
			}
		}

Notice i left out the Title and Description fields, i feel that since they are kind of standard that leaving them out is ok to do, makes it easier to read and they are standard so they will be some kind of common tie among the different content types. So now we have our Content Type created, we only need to do one more thing to have a basic working extension here and that is to define the controller. This part might be confusing to people coming from other MVC frameworks as they are included in the same file, I didn’t like it at first but it really is ok and you will get used to it. Notice that in the getCMSFields() function that we are adding “Root.Content.ClassInfo” That is basically the tab at the top of the admin interface to let you know it is separate from the main content tab. So at the bottom of the model start a new class and leave it empty, since we are not needing to customize the existing Page_Controller.

	class ClassPage_Controller extends Page_Controller
	{
	}

So our entire file should look like this:

	class ClassPage extends Page
	{
		static $db = array(
			'ClassInstructor' => Varchar(64),
			'ClassCapacity' => Int(3),
			'ClassSlotsFilled' => Int(3)
		);
 
		function getCMSFields()
		{
			$fields = parent::getCMSFields();
			$fields->addFieldToTab('Root.Content.ClassInfo', new TextField('ClassInstructor'));
			$fields->addFieldToTab('Root.Content.ClassInfo', new TextField('ClassCapacity'));
			$fields->addFieldToTab('Root.Content.ClassInfo', new TextField('ClassSlotsFilled'));
			return $fields;
		}
	}
 
	class ClassPage_Controller extends Page_Controller
	{
	}

Now we can test it out, the first thing we need to do is go to our site and login to the admin areas. Then in a new tab append the following to the end of the URL /dev. Once you open that page you will see some text and the DB will be updated. Now we can go to our admin area and use our new page type!

There is still more to do but mainly in the TPL files and making sure that your info displays correctly or at least has a default for people to override in their own themes. We will save the theming for next time, it is nice and straight forward too but try this out and see what you think. If there are errors in any of this code let me know, I was mainly doing this as a reference so I didn’t build and run this but it should work just fine.
