Encrypting Your Drive with TrueCrypt

Today I thought I’d try my hand at a video tip, a screencast walkthrough of encrypting your hard disk using TrueCrypt. TrueCrypt whole-disk encryption is a fantastic option to further secure your data against prying eyes, and the software is free and open source. Whole-disk encryption is precisely what you might think it is, encrypting your whole hard disk and locking it down with a password. After your encrypt your disk, you’ll need to enter a password every time you boot up or resume from hibernation to unlock the data on your drive.

Whole-disk encryption is a far superior method of securing your data than BIOS passwords or user accounts; user account passwords are easily bypassed or cracked, and BIOS passwords are locked inside the motherboard rather than the hard drive, so anyone could just yank your drive out of your machine, hook it up to theirs and access your data as if you’d never set a password at all. Whole-disk encryption is per-disk or per-partition, and uses a variety of very high level encryption algorithms, so you can’t get much more secure than this.

Take advantage of Firefox 3’s color profile support

One of the big complaints I’ve heard from the more photographically inclined about Firefox 2 was the lack of color profile support in the browser. The simplest way to explain color profiles (or embedded ICC) is to look at some examples of images rendered in browsers that don’t support color profiles (in the left frames) and those that do (in the right frame.)

Images provided by SmugBlog.

What do you immediately notice? For me, it was the depth of shadowing. What you being to realize as you look at the difference between the images, however, is how much more “real” the image feels to you; the expanded range of colors really makes the images pop out.

When you’re seeing an image on the web with a color profile in a browser that supports color profiles you’re seeing it in a closer representation to what the author intended. At this time, Firefox 3 and Omniweb are the only browsers to fully and properly support color profiles. Safari has a buggy implementation of it, and Internet Explorer… well, it’s Internet Explorer. They’re still scratching their heads over how to CSS working.

How do I enable color management support in Firefox?

Shockingly, Firefox 3 doesn’t come with color profile support enabled by default. This feature was one of the most praised and eagerly awaited aspects of the new version, so I have no idea why they would chose to not enable it from the get-go. Apparently Mozilla chose not to enable the feature by default over performance concerns. On a page with lots of color profile-enabled images this feature can slow down rendering time.

None the less, enabling color profiles is very simple, you can either:

• Install the Color Management extension; keep in mind that the extension is still in the experimental/review phase as of this writing, so you’ll need an account with the Mozilla Addons site to get it.
• Alternatively, you can enable profile support by hand, which is actually very simple and the method I recommend. In Firefox 3, type about:config. If you get a warning, just say OK and continue on. In the filter bar, type: gfx.color_management.enabled. It should have a state of “false”. Double click it to turn it bold and toggle it to “true”. Restart Firefox.

You can test if your color profile support was successfully enabled at this site. Another great demo page is over at SmugMug- try loading it in Firefox 3 with color profiles, then Internet Explorer or Safari. Big difference, no?

How do I export my images from Photoshop with ICC profiles?

By default Photoshop does not embed color profiles in images exported using the Save to Web & Devices interface. To enable this, choose the JPEG format and checkmark “ICC Profile”. Simple as that.

Getting FolderShare for Mac to Play Nice

I’ve been using Microsoft’s FolderShare (now Windows Live FolderShare blah blah blah) service for years now, and I’ve got to admit that as much as I hate most of Microsoft’s Live apps, FolderShare is one utility that I couldn’t live without. Well, OK- I could, but I wouldn’t want to.

My recent addition of a shiny new MacBook Air to the household introduced an odd problem; while my Mac Pro has never had issues syncing files to the PCs in the house using FolderShare, the Air refused to do so. After some cursing, I did a bit of Googling and came across the solution.

Disable FolderShare encryption across all the Macs and PCs you want to sync. Yep.

Now, don’t ask me why my Mac Pro didn’t have the problem with encryption; both machines run Leopard, and neither have their Firewalls enabled. In any case, disabling encryption solves the problem, though I’m not at all a fan of the fact that my data is getting tossed around in plain text now. I suppose I could funnel everything through my Hamachi network to encrypt it, but… bleh.

Anyway, there’s the solution, Mr. Googler with a Mac. Hopefully Microsoft will fix the problem sooner rather than later, but if their track record with FolderShare updates is any indication I wouldn’t hold my breath. I’m hoping to get a Dropbox invite to see if it’s a worthy replacement. Stay tuned on that.

Resolving “Unsupported Operating System” Error in Windows Media Player 11

Fresh install of your slipstreamed Service Pack 3 media and missing Windows Media Player 11? Microsoft has yet to update the WMP11 download to support clean installs for Media Center with Service Pack 3, but here’s a fix that should work on any XP installation where you encounter the problem:

1. Download Windows Media Player 11
2. Using WinRAR, 7zip or any other archiving app that can support it, extract wmp11-windowsxp-x86-enu.exe.
3. Run wmfdist11.exe from those extracted files.
4. Run wmp11.exe, also from those files.
5. Enjoy.

Encountered this issue this afternoon, so I thought I’d share a fix. Good luck.

Intel Pro/Wireless 2200BG Disconnects on Apple Airport

I’ve had my laptop (a Dell XPS Inspiron Generation 2) for almost three years now. It’s still running strong, and overall I’ve been pretty happy with it. However, since day one I’ve had one majorly aggravating issue with it: the Intel Pro/Wireless 2200BG card disconnects. Like, a lot. Frequently. Several dozen times a day. I called Dell support on several occasions, and they were never able to really help. They replaced the card once to no avail. Now that it’s out of warranty, I kind of gave up on making the stupid thing work.

Then I decided to Google one day… go figure.

So it turns out the Intel Pro/Wireless 2200BG (and, I presume, other Intel wireless products) has a feature called PSP, or “Power-Save Polling”. Essentially the technique causes the wireless card to switch between an active and low power passive operating state, reducing power consumption and boosting battery life for your laptop. That’s all well and good, but the technology requires that the router you’re using supports this feature, as both sides of the process must cooperate in a unique manner to keep the connection alive during the lower power phases.

Surprise, surprise: Apple’s Airport line (Airport Extreme, Airport Express, etc.) doesn’t support PSP.
