Chronos' Acolyte Mac OS

I recently got my hands on one of those Google ChromeBooks (Cr-48). Interesting to have an operating system that is just a web browser. But, as anyone likely reading this article already knows, the graphical interface is the web browser and the operating system is still Linux. But what version? Well, let's go on a journey together.First, you need ChromeOS. If you've got a ChromeBook this is a pretty easy thing to get. If not, check http://getchrome.eu/download.php for a USB or optical download that can be run live (or even in a virtual machine). Or, if you know that you're going to be using a virtual machine, consider a pre-built system from hexxeh at http://chromeos.hexxeh.net/vanilla.php. I have found the VMware builds to be a bit persnickety about the wireless on a Mac, whereas the VirtualBox builds ran perfectly. I split my time between the two anyway, so I've just (for now) been rocking VirtualBox for ChromeOS. When you load it for the first time it asks for a Google account. Provide that, select your network adapter, choose from one of the semi-lame account images ( for the record, I like the mad scientist one) and you're off to the races.Next, we need a shell. When you first log in, you see a web page that shows you all of the Chromium apps you have installed. By default, you'll see File manager and Web Store. If you've used the OS X App Store then the Chrome Web Store is going to look pretty darn familiar. My favorite for now is Chrome Sniffer. But all of these kinda' get away from where we're trying to go: get a scripting environment for Chrome OS.Chrome comes with 2 types of shell environments. The first is crosh. To bring up a crosh environment, use Control-Alt-t. This keystroke invokes the crosh shell. Here, type help to see a list of the commands available. Notice that cd, chmod, etc don't work. Instead, there are a bunch of commands that a basic user environment might need for troubleshooting primarily network connections. 'But this is Linux' you ask? Yup.At the help output you'll notice shell. Type shell and then hit enter. The prompt will change from crosh> to chronos@localhost. Now you can cd and perform other basic commands to your hearts delight. But you're probably going to need to elevate privileges for the remainder of this exersize. So let's type sudo bash and just get there for now. If you're using a ChromeBook, the root password might be root, or if you're using a downloaded vm from hexxeh then it might be facepunch (great password, btw).Provided the password worked, the prompt should turn red. Now, if you're using a hexxeh build then the file system is going to be read-only. You won't be able to change the root password nor build scripts. But otherwise, you should be able to use passwd to change the password:passwd chronosOnce you've got slightly more secure shell environment (by virtue of not using the default root password), it is time to do a little exploring. Notice that in /bin, you see sh, bash, rbash and the standard fare of Linux commands (chmod, chown, cp, attr, etc. Notice that you don't see tcsh, csh or ksh. So bash commands from other platforms can come in, but YMMV with tcsh, etc. Running ps will give you some idea of what's going on process-wise under the hood:ps auxFrom encrypts to crypto to the wpa supplicant, there's plenty to get lost in exploring here, but as the title of the article suggests, we're here to write a script. And where better to start than hello world. So let's mkdir a /scripts directory:mkdir /scriptsThen let's touch a script in there called helloworld.sh:touch /scripts/helloworld.shThen let's give it the classic echo by opening it in a text editor (use vi as nano and pico aren't there) and typing:echo 'Hello Cruel World'Now close, save and then run it:/scripts/helloworld.shAnd you've done it. Use the exit command twice to get back to crosh and another time to close the command line screen. You now have a script running on ChromeOS. Next up, it's time to start looking at deployment. This starts with knowing what you're looking at. To see the kernel version:uname -rOr better:cat /proc/versionGoogle has been kind enough to build in similar sandboxing to that in Mac OS X, but the concept that you can't run local applications is a bit mistaken. Sure, the user interface is a web browser, but under the hood you can still do much of what most deployment engineers will need to do.If these devices are to be deployed en masse at companies and schools, scripts that setup users, bind to LDAP (GCC isn't built-in, so it might be a bit of a pain to get there), join networks and the such will need to be forthcoming. These don't often come from the vendor of an operating system, but from the community that ends up supporting and owning the support. While the LDAP functionality could come from Google Apps accounts that are integrated with LDAP, the ability to have a 'One touch deploy' is a necessity for any OS at scale, and until I start digging around for a few specific commands/frameworks and doing some deployment scripts to use them, right now I'm at about a 6 touch deploy… But all in good time!This faq contains instructions for installing StickyBrain under Tiger and also provides help if you've already installed Tiger and StickyBrain is not working.

First Time installation of StickyBrain Under Mac OS X 10.4 Tiger

If you have already installed Mac OS X 10.4 and are installing StickyBrain for the first time, all you need to do is download StickyBrain 3.5.0 or higher from www.chronosnet.com and run the installer.

Already installed Tiger and StickyBrain is Not Working

If you did an archive and install when installing Mac OS X 10.4 Tiger and you previosly had StickyBrain installed under 10.3 Panther, StickyBrain may a) hang on 'Opening Database'; b) open to a blank database; or c) open but you can't restore from a backup or .Mac. To solve any of these issues perform the following steps:

Knights armour mac os. 1. Open the following directory: /Previous Systems/Previous System 1/Library/OpenBase/Databases/

2. Move the file named 'StickyBrain_yourusername.db' to the Desktop. Depending on what version of StickyBrain you were running before the Tiger upgrade the file may be called 'Chronos_yourusername.db'.

3. Move any other files from this directory that are used by other applications to the Desktop.

4. Download StickyBrain 3.5.0 or higher from www.chronosnet.com

5. Launch the StickyBrain installer and at the screen before you install StickyBrain choose 'Uninstall' from the Easy Install popup menu and then click the Uninstall button. When asked, choose to uninstall OpenBase. This will uninstall StickyBrain and OpenBase from the computer (OpenBase is the database engine StickyBrain uses to store the notes in).

6. Launch the StickyBrain installer and this time install StickyBrain. At the end of the installation you'll be asked to restart your computer.

7. After your computer has restarted launch StickyBrain. This will create a new database.

After this step if you have a backup file or a backup on .Mac you will be able to restore your notes from it. To restore from a backup choose File > Restore All Notes, and then select the backup file and click Open. If the backup is on .Mac choose File > Restore All Notes From .Mac.

If you did an archive and install when installing Tiger you should have access to backups of your StickyBrain database. By default backups are created in the following directory (where '~' denotes your home folder):

~/Library/Application Support/StickyBrain/Backups/

If, however, you don't have access to a backup and the only copy of your notes are stored in the database that you pulled out of the /Previous Systems/Previous System 1/Library/OpenBase/Databases/ directory in Step 2 above, do the following steps:

1. Launch the OpenBase Manager application, which is located in the /Applications/OpenBase/ directory.

2. Click the Local button.

3. Select the StickyBrain_yourusername/Chronos_yourusername database in the list and choose Action > Stop Database.

4. Choose Action > Delete Database.

5. Quit Openbase Manager.

6. Drag the StickyBrain_yourusername.db/Chronos_yourusername.db that is on the Desktop into the following directory: /Library/OpenBase/Databases/.

7. Launch the OpenBase Manager application.

8. Click the Local button.

9. Select the StickyBrain_yourusername/Chronos_yourusername database in the list and choose Action > Start Database.

10. Launch StickyBrain and you should have access to your notes.
