As part of my trade, I work a lot with colors. ColorSchemer Studio has long been a valuable tool in my toolkit for picking out color schemes based on solid color theory. It had its shortcomings, though, and some other tools had surpassed it, both on the desktop and on the iPhone. However, I got a sneak peek at the up-and-coming version 2.0 of ColorSchemer Studio, and I'm willing to say that it's poised to regain its lead in the field.

ColorSchemer Studio 2 adds an amazing number of new features, and improves on just about every aspect of the existing toolkit. Firstly, I want to highlight that it can now work entirely in the CMYK gamut, if you choose. Screen colors are adjusted to a CMYK profile, and there are export options to match. That's a big deal for those who take their colors off the screen and into the real world. Even though many modern presses can actually get better color from an RGB file, CMYK still rules in the world of offset printing. While it's a huge step for this app, it's not the coolest part ... read on for an in-depth preview.

I had the opportunity to speak with the creators of Checkout: an excellent Point of Sale application for the Mac. I've been working with the app for several weeks now and have been thoroughly impressed by it, especially after the developers shared their perspectives. Many thanks to Ed and Dirk for walking me through it.

Whether you're starting a new store or transferring your current system to Checkout, it's the best Point of Sale I've worked with in my many years of retail. The creators explained that they designed Checkout to help small and mid-sized retail stores make sales, print receipts, manage stock, organize customers, and collect payments.

This application focuses heavily on ease-of-use in everything from installation to managing metrics and allows the user to remove "unneeded complexities" from the system they work with every day.

Read on for a full walk-through of the application.

MacUpdate announced today the release of version 5.0.2 of the MacUpdate Desktop utility, which allows users to manage application and widget software updates on their Mac OS X machines. The new version of the application adds some features and bug fixes as well as support for more languages.

MacUpdate Desktop can track software updates for 30,000 Mac applications, and it also provides update support for applications on the iPhone, although iTunes handles that pretty well. Updates can be triggered manually and individually, or set to install automatically when MacUpdate Desktop is open. It also provides support for updating screen savers and allows users to sort applications into "watch lists," so they can keep track of programs that are more important to keep current than others.

The update includes improved handling of the software it tracks, such as version and application matching, as well as French, German, and Italian localization. Some of the bugs it fixes are community preferences, registration problems, and issues with extracting tar bzip2 and dmg.zip downloads.

There are several update managers out there for Mac OS X (including AppFresh, LogicielMac, VersionTracker Pro, etc.) with fans and detractors of their own. If you've had great or not-so-great experiences with any of the updater tools, let us know in the comments.

It must be nice to be Evernote CEO Phil Libin right now. His company's product / service, Evernote, is about to break 2 million customers, they're past the days of initial development and beta testing, and the future is looking bright.

I had a chance to chat with Mr. Libin last Friday about Evernote, the service that acts as a cloud-based repository for all of the information in your life. Last year during the closed beta test of the service, TUAW's Brett Terpstra interviewed Libin, who called Evernote "universal human memory extension." Whatever information you want to put into the Evernote cloud -- text, photos, voice memos -- is available for searching and viewing from your Mac, PC, or iPhone. Handwritten or printed text runs through a recognition routine that makes it searchable text, something that I've found incredibly useful when storing my business cards in Evernote. You can send web pages to Evernote from Firefox with the click of a button, or tweet notes to Evernote by addressing them to @myEN.

Libin ran me through a short history of Evernote, mentioning that many of the first reviews and discussions of it were provided by TUAW. The Mac app and the service began a closed beta in February, 2008, moving to an open beta in June of that year. As Libin noted, "We never really told anyone when we came out of beta; we just gradually removed the word 'beta' from the site and the software." Since then, Evernote has signed up almost 2 million users.

When I asked Libin if Evernote was meeting the company's expectations in terms of growth, he replied that "we're right where we thought we'd be now." In terms of the present and near future, there's a lot going on. Localized versions of Evernote will be available by the end of 2009 for several European countries, with a Japanese localized version on tap for early 2010. Libin noted that "the Japanese market is huge! Evernote is listed in many Japanese magazines, half of our Twitter traffic is in Japanese, and we're even thinking about opening an office in Japan."

Most of us have really crappy, insecure passwords. Sure, we tack a couple of numbers or punctuation characters at the end of our cat's name, but that's a far cry from secure -- especially since we also have the equally nasty habit of using the same password on every single site/service/machine/device with which we have regular contact. We're not just asking for trouble, we're offering it a delectable stolen identity sandwich.

As most of us Mac folks know, a solution exists and it's called 1Password. If you've owned your Mac for more than an hour or so, chances are pretty good that you've been admonished to acquire this lovely app (maybe even by more than one person). Several of us at TUAW are big fans of 1Password, and today our pointy party hats are standing taller than ever thanks to the opening of the public beta for 1Password 3.

This new version brings with it a massive list of changes, improvements and new features -- a couple of which have helped me to realize the dream of being able to utilize 1Password data on OSes other than OS X. You see, like many other Mac enthusiasts, I use Windows at work. Obviously, this precludes me from fully embracing Mac-only software like 1Password, but thanks to a brand new feature called 1Password Anywhere, my pain is dulled.

1Password Anywhere allows you to take your 1Password data and open it using any modern web browser. I've tested this with Chrome, Firefox and IE under Windows XP and they all work wonderfully. Your data is still absolutely secure and stored behind the same master password that protects the data in 1Password proper. They didn't spare any detail, either -- 1Password Anywhere looks and feels remarkably similar to the native OSX application. The data is read-only in your browser, but being able to easily the strong passwords and paste them is worth the admission price. The truly enlightened will see the application of a service like Dropbox here -- just move your keychain file into your Dropbox and your passwords are now with you whenever you go.

"Where did all my disk space all go?"

When I was in college, each student was allotted 4 megabytes ('mega' is not a typo) of disk space for both email and files. Granted, this was back in the early '90s, before anyone had heard of "www." or had even thought of ".mp3" or ".mp4". In 1995 I acquired a 1GB hard drive and felt like king of the known world. Sure, it was in a case about the size of a loaf of bread, but an entire gigabyte! All to myself! Today I have a Drobo which is in a case roughly the same size as that 1GB drive, but it has 2 terabytes of redundant storage -- 2,000x the space on that prime example of mid-90s storage tech.

One thing hasn't changed: there's still never enough hard drive space. It seems to be as unavoidable as death and taxes. That Drobo? It's about 95% full.

Enter OmniDiskSweeper, a freeware program by The Omni Group which will allow you to find where your diskspace has gone. Now, there are a number of different programs out there for analyzing your hard drive space: DiskInventoryX, GrandPerspective, Baseline, DaisyDisk, and WhatSize, to name just a few. Choosing one may be as personal as which Twitter client or web browser you prefer. I like OmniDiskSweeper for two reasons: it is free and it is simple. It uses the same "Column View" that I use in Finder, and automatically sorts the folders which use the most disk space to the top.

For example, looking at the Drobo, I can see that about 50% of the space on that device is taken up by programs I have recorded using Elgato's EyeTV. You might also find files in unexpected places. A friend recently used OmniDiskSweeper and realized that he had tried to copy a bunch of files to an external hard drive, but something had gone wrong. Instead of moving the files to the external drive, they had just been moved into a folder in /Volumes/.

OmniDiskSweeper makes it easy to delete files right through the app; simply select the file and click the big red "Delete" button. A word of warning! A warning dialogue box will appear, asking you to confirm that you want to "Destroy" the files. They will not be sent to the Trash (since the assumption is that you are running OmniDiskSweeper because you want to reclaim diskspace), they will be deleted immediately.

The Omni Group made OmniDiskSweeper (along with several other utilities) free a few months ago, so if you looked at it and were turned off by a price tag, give it another look. It may not have as many bells and whistles as some of the other programs out there, but it's hard to beat OmniDiskSweeper for ease of use.

UPDATE: TUAW reader "ithinkergoimac" comments below that OmniDiskSweeper may report incorrect (significantly increased) file sizes if you are using TimeMachine.

The iPhone app platform TapLynx from NetNewsWire was released yesterday, after months of anticipation. TapLynx provides you with a way to build media-rich iPhone applications without having to write any code. It's basically NetNewsWire's way of leveraging their RSS expertise along with their iPhone development skills, in the form of Brent Simmons.

Although TapLynx users don't need Cocoa knowledge, if you're a Cocoa developer you can use TapLynx to quickly add media management features to your app. In fact, NewsGator distributes TapLynx as a Software Development Kit, making its development roots fairly obvious. Beyond the ability to customize the user interface and choose the feeds you want your app to display, TapLynx offers the unique feature of being able to do remote updates to the app. This means that you can change a number of things in the app including the look-and-feel without requiring an update to be submitted to the frustratingly slow App Store.

Brent Simmons, the developer behind TapLynx, is the guy behind the perennial Mac favorite RSS reader, NetNewsWire. What many people don't know is that before he did NetNewsWire he worked at UserLand, creating tools for developers. So in some ways this is Brent returning to his roots.

[Update] As commenters have pointed out, the pricing for TapLynx is a little over the top: $3,499US for an Enterprise license, which is the only type of license they offer. That makes the news of TapLynx's release a little less interesting, in my opinion.

I love everything about my MacBook Pro, but for some reason it does not like to share its screen. It appears under the "Shared" section of the sidebar in Finder, and file sharing works perfectly, but for some reason screen sharing won't work. The "Connecting To 'MacBookPro'" panel will pop up and then disappear a few moments later (as if it is about to connect), but at least 90% of the time no screen sharing window appears.

Fellow TUAW writer Aron Trimble suggested that I go into Finder and try "Go > Connect to Server" and then put in "vnc://10.0.x.x" (where 10.0.x.x is my MacBook Pro's IP address). That worked immediately, and every time.

This confirmed that it wasn't a firewall setting (Screen Sharing is explicitly on) or trouble accessing the MacBook Pro over the LAN (file sharing already worked perfectly). For some reason the screen sharing connection was just not being made over Bonjour.

The only drawback to this direct-IP method is that my network, like most, uses dynamic addresses with DHCP, meaning that the IP addresses change from time to time, especially on a network with multiple devices which are not always turned on. My first thought was to create a static IP for the MacBook Pro in System Preferences > Network, but then I realized that my office LAN uses IPs which start with 192.168.x.x. I could create a new network "Location" but that would also involve manually switching it back and forth, or using a third-party program.

What I really needed was a way to make sure that my MacBook Pro is given the same IP every time it connects to my home LAN. Fortunately, Apple's Airport Extreme will allow me to do just that using DHCP Reservations.

A DHCP Reservation tells the Airport Extreme to reserve a certain IP address for certain computers, as determined either by a "DHCP Client ID" or the computer's MAC address. A DHCP Client ID is easier to remember than a MAC address, but the MAC address will never change unless you swap out the logic board or Airport card of your Mac. I'll show you how to set it up using either method.

We've mentioned Dropzone before as a Friday Favorite, but I just happened across the app while I was trying to solve a problem.

I suspect many TUAW readers find themselves in the same situation that I am in: I use a desktop and a laptop. I often find myself wanting to move files between these two machines, so here's what I do: switch to Finder, click on the shared Mac I want, navigate to the folder I'm looking for, and then track down the file I want to copy there and drag it over. I could drag a folder from the other computer to my "Places" sidebar in Finder, but honestly, I just never do.

What I wanted was something quick and painless. I tried to whip something up using Automator and Folder Actions where it would copy/move files saved in one folder to the other machine, but even that would get messy. Most often I don't want to move the file, I just want to copy it. I could put the files in Dropbox, but some of these files are sizable (i.e. the 30+ MB iMovie update). To use Dropbox for this would take a long time.

Turns out that Dropzone offers the perfect solution: by enabling FTP on both Macs (System Preferences > Sharing > File Sharing, then click the "Options" button, and check the box "Share files and folders using FTP") I now have a drag & drop solution to copying files between computers. Simply drag the file to the Dropzone icon on the dock and then drop it onto one of the many "dropzones" which I have defined, and Dropzone does the rest. Two folders that I added almost immediately? The "Automatically Add to iTunes" folder in the iTunes folder and the Auto Import folder from inside my iPhoto Library (you will have to control-click your iPhoto library and choose "Show Package Contents" to find the "Auto Import" folder).

There are several plugins available to extend Dropzone to other services such as ImageShack, TwitPic, Flickr, and more. For Internet services, not only will the file get copied to where you want it to go, but the URL will be placed on the clipboard so you can paste the URL wherever you want it to go. I often FTP files to my website, and files Dropzone FTPs to a website can also support putting the URL on the clipboard.

There are several other nifty options, Dropzones for starting the screensaver, putting your Mac to sleep, or drag & drop printing a file to the default printer. You can also zip files (or zip and email them) and many other conveniences.

The biggest feature of all was one that I almost overlooked until I watched a screencast from macosxscreencasts.com about Dropzone. A built-in Dropzone called "Install Application" will allow you to drag a .dmg onto Dropzone and have the DMG mounted, the app installed to /Applications, the DMG moved to the recycle bin, and the app launched (it also works with applications which have been .zip'd instead of put into a disk image).

If you are anything like me, the "install a new app" process is several steps that you repeat a lot. Dropzone's handling of it is incredibly fast and works really well. If it opens a DMG it cannot handle (such as an installer), it will simply open the folder. Great, start stuff that saves you time and frustration. Remember how computers were supposed to make our lives easier? Dropzone does just that.

Sometime this summer a wiseacre commenter (we get a few) suggested we do a "Five Apps" for a variety of somewhat offbeat topics. One wasn't so far-fetched however: gastroenterologist. One could say that a gastro doc has about the same needs as any doctor, of course, and that's an easy out. So here are 5 apps that are great for gastroenterologists and possibly any medical specialist... Coming soon: 5 apps for the lemur owner.

Epocrates Rx - This free app looks up drugs and is updated weekly. Epocrates [iTunes link] has already been available for other mobile platforms for a while, this is a must-have for physicians, I would think. There's also a Pro version that is designed for medical professionals, and it requires a yearly subscription fee to work. It's $99 for one year, which is pretty reasonable for what this does -- which includes an amazing pill ID tool.

DocWrite - Another free app with a service you subscribe to, but this may appeal to more than doctors. DocWrite [iTunes link] is a transcription service that sends your ramblings securely and sends you back a complete transcription in PDF or Word. DocWrite has a web-based dashboard for your stuff, too, so you'll never be without those documents in text or audio.

PubSearch - PubMed is a massive database of medical research papers and PubSearch (free version) [iTunes link] is an iPhone app that'll search them. Yes, of course you need a subscription to the database (noticing a trend here?). PubSearch also has a Mac desktop app, although there does not seem to be any coordination between the two. I'd imagine something like sharing bookmarks would be helpful. PubSearch Plus [iTunes link] costs $1.99 and is really the more functional version as it will show full articles and use EZProxy (where supported).

Medcalc - A free medical calculator? Yep, Medcalc [iTunes link] includes a ton of formulas for doctors, plus a few indices and charts and whatnot to keep a handy reference for those who need it. This app seems to cover a lot of ground, although I'm not sure how much applies to the field of gastroenterology.

Mobile MIM for iPhone and iPod touch - Sadly, this has yet to be released. But I'm guessing it'll be at the top of many doctors' wish lists. MIMvista makes real-deal medical imaging stuff and the MIM app for iPhone was demonstrated at WWDC. The demo was astounding, showing how doctors could merge CT and PET scans right on their iPhone and make notes for later use. The app is pending FDA approval, with no release date or price set.

When TextExpander touch for the iPhone was announced, one of the exciting aspects was the SDK to allow other developers to integrate TextExpander's technology into their iPhone apps.

The new version of WriteRoom for iPhone now includes TextExpander support. With this announcement, SmileOnMyMac has announced that they will be selling TextExpander touch for $1.99 until September 30 at 12 noon Pacific Time, a 60% discount off the regular price of $4.99.

WriteRoom for iPhone 2.1 includes other updates as well, as noted on the development blog:

• TextExpander support.
• Optional startup password.
• Settings are now accessed within app.
• New option to lock screen orientation.
• Sync service is out of beta and is open sourced.

If you purchase WriteRoom for iPhone ($4.99 on the App Store), you'll get a $5 off coupon that can be used to purchase either WriteRoom ($24.95) or TaskPaper ($29.95) for Mac.

The company's teaser page still says "coming soon," but eagle-eyed reader Jason spotted the free Zipcar app [iTunes link] in the store today. We've been waiting for this app for quite a while, and it's exciting to see it in action.

The app provides Zipcar members with a location-based search for nearby Zipcar locations, allowing them to drill down to the individual garages via a map view. Reserving a car is as easy as clicking one big green button, and the app allows you to sort available cars by time, type and model to make it easier to find the one you want. You can see your upcoming reservations and cancel a car if you don't need it after all.

Once you get to your car, you can use the virtual keyfob to help find it in the garage by honking the horn (nice touch); while you still need to use your RFID-equipped Zipcard to activate the car's remote unlock and ignition system, once you do that at the beginning of your reservation you can put it back in your wallet and use the iPhone to lock and unlock the car. You can also extend your reservation from the iPhone app, as long as there's open time after your slot ends.

One somewhat quirky thing about the app is that there's no way to adjust your reservation time window except at the 'top' of the car search process; often as not, with the Zipcar website, you may find yourself tweaking the hours of your booking to improve your chances of finding the car you need. The lack of flexibility is noted on the app's iTunes page under "Coming Soon," so a future release will probably improve matters here. The Zipcar app requires iPhone OS 3.0 and works on the iPod touch as well, although most features will require a network connection.

Zipcar members are almost as enthusiastic about the service as iPhone owners are about their devices, so this combination is sure to strike sparks. Once you've got the Zipcar app downloaded, let us know your road trip experiences via the comments below.

Every "point-oh" version of Mac OS X usually brings some small bit of pain, as I find some little utility no longer works. Snow Leopard has been no exception. I had been using the version of Screen Sharing from 10.5.4 because it had some "hidden" features which I liked. Unfortunately those "hidden" features were also "unsupported" features. When 10.5.5 came out, they were gone, but I continued to use the version of Screen Sharing from 10.5.4 which worked until 10.5.8. Sadly for me, it does not work at all in 10.6.

The biggest drawback of Screen Sharing was the removal of the Bonjour Browser, which showed a list of computers available for Screen Sharing (both locally and via Back to My Mac). Now I had to type them in manually, which isn't such a big deal when you are trying to connect to a machine on a local network. If you are trying to connect over the Internet, however, you need to use the full hostname, which may look something like this: macbook.yourname.members.mac.com. Plus, it just seems like one of those things that the computer ought to do for me. [Side note, if you are looking for a handy way to see all the Bonjour services on your local network, check out Tildesoft's free Bonjour Browser utility.]

While looking through a bunch of old files in my ~/Downloads/ folder, I found a version of ScreenSharingMenulet. I checked its webpage and saw what I was looking for: "ScreenSharingMenulet 1.7.1 and higher is compatible to Mac OS 10.6 Snow Leopard." ScreenSharingMenulet sits in the menu bar along with your other menu extras. Simply click on its icon (shown above) and choose which computer you wish to connect to via a dropdown list. In my testing it worked very well over a LAN although it did not seem to pre-populate with the machines over the Internet. Given the flakiness of Back To My Mac over ther Internet, I can hardly fault this program for that shortcoming.

ScreenSharingMenulet is free (donations accepted) from Stefan Klieme who has several other handy-looking utilities at his website. If you use Screen Sharing a lot, it's definitely a handy tool to have around.

My Friday favorite is SpamSieve. We have mentioned it a few times previously, but since it has recently been updated to version 2.76 I wanted to sing its praises again. It's the best way I've found to deal with spam.

Using Bayesian filtering, SpamSieve installs as a plug-in to your mail client and lets you mark messages as spam. As you do, it builds a a corpus file of rules telling determining what is spam and what isn't. The more messages you mark, or train, the more accurate SpamSieve gets. I've been using it since November of 2003 and after years of training, it's so accurate that it rarely fails to catch an errant spam encrusted message. When it does, using either a keystroke sequence or a pulldown menu from your Mail client you can train it as spam.

At the start, it's quite labor intensive since you have to mark a few hundred messages for it to really start working, but it pays dividends. After a while, you'll have a personalized set of inclusion/exclusion rules that gets better over time. To give you an idea, yesterday I received 307 emails. Out of those SpamSieve correctly marked and moved over 30 messages and missed only 2 that needed training.

When you only have a handful of Macs in an office or household to upgrade to a new operating system, it's no great problem to run around with the installation DVD and upgrade one machine at a time. But when you're supporting a large office or school environment, it's impossible to take the time to manually upgrade each machine. That's where tools like Apple Remote Desktop and LANrev come in handy.

LANrev 5.2 has been released today, with full compatibility with Mac OS X 10.6.1 Snow Leopard. LANrev uses a proprietary imaging process that saves the home directory and OS settings of each machine during an automated OS deployment, so that the users are back up and running as quickly as possible afterwards.

IT professionals can not only roll out Snow Leopard faster using LANrev, but the application also tracks Snow Leopard machines for asset inventory and provides for remote management of Macs. LANrev has an asset inventory for storing license numbers and purchasing information, which is critical for audits. LANrev can track the location of stolen Macs and provide law enforcement officials with information to locate and recover the machines. For those who are concerned about power usage, LANrev does automated power management of large Mac installations, putting Macs to sleep or shutting them down when they're idle.

Unlike Apple Remote Desktop, LANrev works in cross-platform environments, so it's useful for situations where a small group of Mac users may exist in a Windows world -- or vice versa. No pricing info is available on the LANrev Web site, so be sure to contact one of their distribution partners if you're interested in this professional administration tool.
