In addition to gmail-style email hosting for your domain (and ThunderBird and Outlook hookup instructions to boot), GAppsFYD, as LifeHacker calls it, sports Docs, Chat, and Calendar, all private to specified users of your domain. It also includes Web Pages, giving you space to host static web pages (but you have your own server for that — right?); Sites, a collaborative intranet-style hosting space; and a Start Page, a central page from which all domain users can access the activated services. Best of all, you can activate/deactivate whichever services you choose, allowing only what you need.

Each domain you set up with Google Apps can accomodate up to 100 users under the free version. If the email service is activated, each user gets their own inbox with up to 6GB of storage. You can also setup multiple addresses per user (with one shared inbox amongst them), and a “catchall” email address, where mail sent to a nonexistent user will end up. And, of course, you get all the standard advantages of gmail.

Backing up a Thunderbird or Firefox profile is important, too. Especially if you’re like me, and it would take hours to get Firefox just perfect again after having your profile wiped (if, for example, the drive it was sitting on were to fall to minor corruption). Hunting down that perfect theme (what was it called again?), rounding up all those can’t-live-without extensions…

Under Windows

Under Windows XP (and presumably Vista as well), the default profile for Firefox is found under C:\Documents and Settings\<user>\Application Data\Mozilla\Firefox\Profiles\XXXXXX.default, where that last XXXXX is a random string of numbers. Thunderbird’s profile is located under C:\Documents and Settings\<user>\Application Data\Thunderbird\Profiles\XXXXXX.default. If you’ve used “firefox -ProfileManager” or “thunderbird -ProfileManager” to change your profiles around, these will be different.

Under X/K/Ubuntu

Under Kubuntu (and presumably most or all flavors of linux), Firefox’s default profile is under ~/.mozilla/firefox/XXXXXX.Default User. For Thunderbird, it’s ~/.mozilla-thunderbird/XXXXXXX.Default User.

Methods of backup

A quick google search can turn up lots of methods of backup, including MozBackup. While I haven’t used this extension myself, I’ve no doubt that it works to some extent (or else it wouldn’t have lasted as long as it has). If you prefer GUI solutions, by all means, try it out.

My preferred method, however, is to make a .7z archive of my profile directory (make sure TBird or FireFox is shut down before you zip the archive, though!) This essentially takes a snapshot of the program (including extensions, skins, even open tabs and windows if the “Show my windows and tabs from last time” option is set!); if your profile ever gets corrupted, you can simply unzip the “saved profile” over the current profile, restoring it to the “last known good configuration”, to quote windows.

Another advantage to the zip-it-up method is that you can create “holes” in the profile. For example, with the “Show my windows and tabs from last time” option set, Firefox will leave a sessionstore.js file inside the profile directory; the next time Firefox opens, it reads this file and re-opens all your tabs from last session. Deleting this file from the zip archive creates a profile hole that the more up-to-date sessionstore.js can fit into. Very handy at times.

Here’s the background: our family computer has almost a one-to-one ratio of user accounts to users; unfortunately, when surfing the internet/checking email, my parents tend to just use whichever account happens to be active when they sit down. So, I had to find a way to make their email account available to every account without having to manually add the email to every single Windows account (Oh, the horror!).

So, after a little file-browsing, I finally managed to do it. Best part is, if I want to add another email account to all Windows accounts, I only have to add it once. The worst part is that you can’t have an email account on just one Windows account, unless that account works under its own profile, which defeats the purpose.

Anyway, on to the how-tos:

Prep the folder structure
You will be pointing all Thunderbird client instances to the same mail directory on your hard drive, so you should *ahem* quarantine a specific folder for TBird to dump all its email in. I created a directory email under C:\Program Files\Mozilla Thunderbird\ .

Create a base profile
First you want to create a new profile that you can work with as a base. Go to Start->Run… , type cmd, and press Enter. This will bring up a command line. Navigate to your TBird program folder and run thunderbird -profilemanager:

> cd “C:\Program Files\Mozilla Thunderbird”
> thunderbird -profilemanager

Once the little profile manager pops up, click “Create new profile…”, click Next. Give your profile a name (I used my family’s last name), then select “Choose Folder…” and select the folder you setup in step 1. Click finish. Optionally, you can delete your “default” profile and/or any profiles you won’t be using from here out. Finally, select the new profile and click Start Thunderbird.

At this point, you may want to setup an email account under the new profile to see if it carries over to the other Windows accounts. After that, exit TBird.

Copy the profile settings to all users
In the C:\Documents and Settings\[username]\Application Data\Thunderbird directory, where [username] is the account name that you created the new profile under, there is a file called profiles.ini . You can open this file in notepad to see the contents. Under my configuration (using the email folder for all users), the contents look something like this:

[General]
StartWithLastProfile=1

[Profile0]
Name=Rowls
IsRelative=0
Path=C:\Program Files\Mozilla Thunderbird\email
Default=1

The IsRelative line tells TBird whether or not the Path line is using a relative (1) or absolute (0) path to the desired email folder. We want 0. Path should point to the folder from step 1.

If you still have other profiles that are listed in profiles.ini, you will only want to copy the contents that refer to your global profile. Otherwise, you can copy the entire file over.

Where you want to copy it is to the C:\Documents and Settings\[username]\Application Data\Thunderbird directory of every other Windows user you want to share email accounts with.

And you’re done. Log into someone else’s account (or have them do it for you), pull up TBird, and see if the email accounts carry over.

Enjoy

But those little storage devices can store more than documents. Duh.

I’m working on getting a business running where I basically come to your computer and clean it. Take out the trash, clean up the spyware, spank the viruses, polish the CPU. Kinda like Geek Squad. Anyway. In this business there are a few essential programs that I will be using, but it’ll get very old very quickly if I have to download each and every one to my client’s computer to run it. Not to mention it’ll take more of their disk space, which is NOT a good thing. One alternative is to lug my laptop around to each person, setup a local file sharing network (somehow) and work on their drive from my comp.

No, thank you.

My solution: portable apps on a 1-gig flash drive. There are LOTS of programs that work from a flash drive, many of them free.

However, in choosing programs for your flash drive, you have to keep a few things in mind.

Size: Programs, along with all their add-on dll files and lengthy EULAs, can take up a good chunk of drive space. And with flash drives, you are limited to the drive’s capacity. So, obviously enough, the smaller the better.

Storage methods: How does the app store information? Most programs use files, but way too many programs use the Windows Registry. This is a BIG no-no for portable apps. On one hand your registry settings won’t be available on another person’s computer, and on the other hand you don’t want to inadvertently edit your client’s registry. As such, you want to make sure any program you bring won’t make registry changes.

Relative path support: Life on a flash drive means never knowing what drive letter you’ll be assigned. Therefore your programs have to be able to cope with changing letters, and they can’t be using absolute paths.

So here’s what my life-on-a-stick currently looks like:

Dock: With many programs come many directories. My file structure is pretty deep. As such, I don’t want to go hunting for my apps with my client’s Windows Explorer. So I downloaded RKLauncher. Yes, you could probably go with another dock program, or even a floating menu app, but I prefer RKL because 1) it’s a dock, and I like docks, 2) it supports both ObjectDock and Yz Dock docklets (don’t worry if that didn’t make sense), 3) it’s a standalone executable, 4) it supports relative paths, meaning it can find my programs even when my flash drive’s letter changes, and 5) it’s FREE!!! Free is very important to me.
Total size of RKLauncher + Dock Icons for all my apps + the following docklet: 3.24MB

Menu Docklet: When traveling, you can’t be sure what resolution the computer you visit will be working with, and you don’t often want to mess with the settings (if you can). As such, your traveling dock will ideally be as small as possible. Enter the menu docklet, KKMenu. It’s not really a docklet anymore, it’s a standalone executable, but as such it should work with any dock that supports shortcuts. The download includes a DOC subfolder with a file help.html that gives a rundown of how to use the program, along with a couple of menu skins. In my installation, I’ve deleted the DOC folder all but one skin (one INI file and one PNG file), and all extraneous files (everything in the root docklet folder other than kkmenu.exe and kkmenueditor.exe). My RKLauncher has 4 links to KKMenu, one for each category Internet, Utilities, Security, and Office. Put together with the two links to local copies of Windows Explorer and Task Manager, it’s a very small dock.

Internet

Internet Browsing: Yes, chances are any computer I walk up to these days will have high-speed internet connected to a browser of the owner’s choice — but I’m not the owner, and their choice may not be mine. I prefer FireFox (along with my choice of skins and extensions), so I downloaded FireFox Portable. The owner has even kindly put up instructions for copying your current FireFox settings for use under the portable version. Must-have extensions I take with me include DownThemAll!, SearchBar Autosizer, Cooliris, and PDF Download for use with Foxit Reader (more later), but it doesn’t yet support relative paths
Of course, since space is limited, you want to set some settings that prevent FFP from using more than it absolutely needs. Mainly this means turning off cookies, disk cache, and history.
Total file size of FFP, extensions, and one theme: 26.4MB
Edit: I talked with the author of PDF Download, and we managed to get relative paths working ^_^ In order to do this, open the PDFD options. Under the “General”, select “Open PDF”. Under the “PDF Opening” tab, select “Use this viewer:”. In the text field to the right, put the relative path to your PDF reader executable, starting at the directory where FFP starts. This method uses a lot of “dot-dot” directory specifications (”../”, meaning “one directory up”), but it is also set-and-forget; once you find the right path, you don’t have to modify it again (unless you’re switching PDF viewers).

Email: While it’s true that most email services have a web interface, I prefer a program that brings all my accounts to the same place. Enter ThunderBird Portable. Along with the Webmail Extension, it can bring just about any account type to the desktop. And, of course, you’ll have to explore the settings to reduce disk writing to a bare minimum.
Total size of TBP and two extensions: 27.6MB

Utilities

Advanced Text Editing: A good program that works like Notepad and has a little extra kick is Notepad++, but for flash drives go with Notepad++ Portable.
Total size: 2.25MB

File Compression: Let’s face it: the ZIP compression format stinks. For all the other formats, the best program out there is 7-Zip, with a portable version. Supports almost every compression format out there.
Total size: 2.08MB

SSH Client: My college career involves a lot of work on Linux computers through SSH clients. All I did here was copy over the SshClient.exe file from my local SSH installation, and it seems to work fine.
Total size: 3.07MB
There is also a portable PuTTY, if that’s your app of choice.

Lightweight PDF Viewer: Down with bulky Adobe Reader, long live Foxit Reader! Download and extract the ZIP file from Foxit’s site, and you have a standalone, lightweight PDF viewer!
Total size: 3.85MB

Other utilities: I have a few other small programs that might come in handy. These are Process Explorer (a bulked-up Task Manager), TightVNC Viewer (viewer executable only, along with a personalized build of UltraVNC Single Click, though I haven’t tried the combo yet), FolderSize, and a small program that creates a System Restore Point (edits the registry, yes, but in this case you want it to ).
Total size of all four apps: 4.91MB

Security

Antivirus: My app of choice for antivirus is actually AVG Free, but I haven’t yet figured out how to run it from a flash drive. Until then, I will use ClamWin Portable.

Antispyware/malware: At the moment, my spyware apps include only files copied over from local installations of Ad-Aware SE and Spybot SD. I have NOT tested these for registry modification yet, however!

Office
My portable office suite is OpenOffice.org Portable. Unfortunately, the installation program doesn’t let you choose which parts to install, and there’s really not much you can remove to save space. I’ve managed to slim my install down to 76MB total, but it’s still bigger than I like, when I’ll only occasionally use Writer and Calc.
Total size: 76MB slimmed, 181MB full install

Last, but not least, I have two files on the root of my flash drive: an autorun.inf and an rklauncher.bat. The autorun.inf is setup to automatically run RKLauncher (setup with some help from lazycoder.com). The rklauncher.bat file is essentially a shortcut in the case that autorun doesn’t autorun. With flash drives (and, therefore, changing drive letters), file shortcuts don’t work, so simple windows batch scripts have to be used instead (setup with a template found on a fatwallet.com post — be sure to use relative paths!).

Altogether, my 1GB flash drive shows 225MB used space, 747MB free space. Plenty of free space for any documents or relatively small downloads I may want to grab
