Dropbox to ferry files around using the public folder, don't miss this time-saving Services add-on.

Once installed, right-click on any file on your Mac, select the 'Services' menu, then choose either 'Move' or 'Copy to Dropbox.' That's it. Your file is moved (or copied), and the public link to the file is copied to your clipboard, ready to send.

Many more useful services are available at Mac OSX Automation.

So you decide to buy a copy of Things from Cultured Code. You've read great things about it (no pun intended), and you're ready to graduate from chaotic analog scratchings on a notepad to an elegant digital management process using an award-winning application.

Impatient, you give the instructions a cursory glance, then begin madly entering tasks. A week later, you note that most of the items you dumped in the inbox during the first week are overdue. Your initial enthusiasm wanes. You want to use this app, but old habits die hard. With a tinge of guilt, you keep reverting to writing down your tasks on a notepad.

One day, you decide to give it another go. You paid for this app, after all. Months go by. In time, you learn just enough (largely through trial-and-error) to use Things as a basic task management tool. Habits are formed. You know how to add new task items, create projects, set due dates, and tag your items. But your list is still chaotic. Your tags are haphazard. You start a project, then abandon it. You tend to stick all of your tasks in the inbox and leave them there. While you've made the switch to digital task management, you know that you're not taking advantage of the power under the hood. You know that—if you took the time to really grok this app—you'd be more productive.

Like many of the other Mac apps you've purchased, Things is a tool you want to learn how to use in the way it was intended to be used—but time is at a premium. And, let's be honest, you just aren't going to take the time to read the documentation.

Enter the screencast. For many people, it's hard to really get how to use an app by reading written instructions. It's much easier (and more enjoyable) to watch a video demonstration.

series of high-quality videos that teach you how to deploy your purchase. These videos are available at ScreenCastsOnline, a one-man show run out of the UK offering high-quality video productions that illustrate how to use the Mac OS and a variety of popular Mac software titles.

If you don't want to or can't afford to subscribe to this service, you'll still find excellent free tutorials here. And if you're willing to invest a modest amount of cash to learn how to better use your apps and operating system, now is the time to grab a membership. This month, ScreenCastsOnline is offering a 50 percent discount. At $57 for a six-month membership, this a good deal. You get a lot for your money.

Disclaimer: I don't subscribe to ScreenCastsOnline, and I'm not sponsored by this operation in any way. But I've viewed many SCO videos and have found that they are uniformly outstanding. Take a look at some of the many free screencasts on offer and decide for yourself. I say that if you're going to pay for a Mac application, it's in your interest to learn how to use it well. I think this is one of the best ways to do this.

Another solid option is Lynda.com. The reason I don't subscribe to ScreenCastsOnline is that I'm fortunate enough to enjoy unlimited access to Lynda through my employer, so my plate is full. This site offers a huge selection of tutorials, enough to keep me occupied for years. If you are in the business of web development, graphic design, video work, photography, audio production, or Flash development, you'll get a lot out of these tutorials.

Here's the difference between the two: SCO is consumer-focused and Mac-centric. Lynda.com is geared towards corporate users who have employees on a variety of platforms with specialized needs. SCO focuses on Mac-specific OS and app tutorials that meet the needs of most Mac users. Lynda.com focuses on professional development and training for higher-end applications/tools like the Adobe Creative Suite or Final Cut Studio. An advantage of SCO is that you can download tutorials and keep them forever. There's no DRM. With Lynda.com, tutorials are online-only. For personal training on the Mac, SCO is the way to go. For professional training, steer to Lynda (and you may want to consider pitching Lynda to your employer. Compared to on-site training courses, it's dirt cheap).

alternativeto.net and iusethis.com.

AlternativeTo is the newer of the two sites, and I really like the approach they're taking. Pick a product (Mac, Windows, Linux, online) and see a user-generated lists of alternatives to that product. There are 15 alternatives to Photoshop for the Mac, for example. While all the alternatives are not necessarily equals to a given app, it at least provides a wide angle shot of what's available. I use it as an exploratory tool to find out about applications I've never heard of before.

The other site, iusethis, is similar. You can look up an app (Mac, iPhone, Windows) to get an idea of how many people use it, to include viewing random user comments of varying merit. As with AlternativeTo, it's easy to link to related apps to explore other solutions. This site is best for taking a quick snapshot of the relative popularity of a given app, what some people are saying about it, and for exploring the most popular apps (according to the self-selected user base of iusethis) in a given category. It's the site I use to get a ballpark estimation of what users think of a given application.

Philip Glass album, which I learned about via Twitter.

To my surprise, I discovered 140 other free MP3 albums on the site. I had no idea.

I’m a big fan of international/roots music, so I was thrilled to find many free albums in this genre. These are all sampler compilations, so it’s hit and miss—but there are some good songs to be discovered. I’m not too surprised about that—the point of sampler music is to get you to buy albums from the featured label, so it’s in their interest to include a solid cross-sample of their best offerings.

Back in the day (just a few years ago, really), I frequently picked up low-cost or free sampler albums from labels in music stores. These days, I tend to get my music online from two primary sources: iTunes and Mondomix (before Mondomix, I frequented the now-defunct Calabash, which was bought out by Mondomix). I haven’t bought much from Amazon.

Here’s my point: iTunes doesn’t offer much in terms of free ‘sample’ music beyond the ‘Free Single of the Week.’ Calabash used to offer a lot of free singles. Mondomix does not, but they do offer streaming radio mixes and a decent podcast (it’s in French, by the way). There are not many online sources that offer a place to pick up free sample compilations anymore. Amazon, it turns out, has some of the best free offerings I’ve come across. Who knew.

At any rate, here’s what I think are some of the best of the lot from Amazon’s current free ‘International’ collection:

- Pressure Sounds sampler: solid reggae and dub tracks.
- Rotana sampler: great collection of Middle Eastern sounds from a huge label.
- Saavn sampler: Bollywood music…you can’t go wrong with Bollywood tracks.
- Anana sampler: interesting collection of music from Israel.
- Epsa world music sampler: ‘tango & folklore’ from Argentina.
- Putamayo sampler: decent sampler of music from around the globe.
- Turkish hits: nice variety of Turkish artists.

A few other albums of note that I picked up from other collections:

- A surprisingly good, wide-ranging compilation of Baroque music.
- A great collection of old music (and I mean old…Medieval and Renaissance period sounds). If you like this sort of thing, by the way, I highly recommend Anonymous 4.
- An album with five solid blues-folk tracks from influential American artists on the Vanguard label (e.g. Odetta, Ramblin’ Jack Elliot).

Oh, and if you’re a Mojo Nixon fan (I’m not), head to the free album store now. Looks like pretty much all of Mojo’s stuff if currently free.

Whatever you’re into, the Amazon’s free MP3 collection is worth a browse.

Note: In case you’re wondering, this site is not sponsored in any way by Amazon.com. Just thought I’d share what I found there.

If you attempted the temporary fix to get your wireless working correctly on your MacBook after the recent Mac OS 10.5.8 update, check out this MacFixIt post before you try to install the patch issued by Apple earlier today.

I reinstalled the 10.5.8 Combo Update, then applied the Airport patch, and all is now working well.

If you are one of the many people experiencing AirPort connectivity problems after upgrading to 10.5.8, here’s a solution that worked for me, found on the Apple Discussions forums from user SpacePirate.

This solution allows you to revert to the 10.5.7 AirPort kernel extension (kext file) without reverting the entire OS back to 10.5.7. It appears that Apple is aware of the problem, so hopefully we’ll see an update soon that fixes this bug.

It’s worth emphasizing that you should not do this unless you are comfortable modifying system files. Ensure you have a good backup. Proceed at your own risk.

- Download the 10.5.7 Combo Update.

- Download and install Pacifist, a handy tool that allows you to extract specific files from an Apple package (i.e. the Combo Update is a .pkg file).

[Pacifist is $20 shareware. You can use it in trial mode to accomplish this task, but if you think it’s something you might use from time to time, consider buying it. It’s helpful for repairing damaged files without reinstalling the entire OS, verifying installations, and finding missing or altered files.]

- Turn off your AirPort.

- Delete /System/Library/Extensions/AppleAirport.kext.

- Delete /System/Library/Extensions/IO80211Family.kext.

- Extract /System/Library/Extensions/AppleAirport.kext from the 10.5.7 package using Pacifist and copy this file to the /System/Library/Extensions/ folder on your Mac.

[Open the 10.5.7 package with Pacifist, find the AppleAirport.kext file in the /System/Library/Extensions/ directory of the package, and extract this file to your /System/Library/Extensions/ folder on your Mac, or copy the file to the desktop, then drag it to the /System/Library/Extensions/ folder on your Mac. Don’t try taking these files from a Time Machine backup unless you know how to properly set permissions for the copied files. If you use Pacifist, the app will set the correct permissions for you.]

- Extract /System/Library/Extensions/IO80211Family.kext from the 10.5.7 package with Pacifist using the method described in the previous step.

- Delete the /System/Library/Caches/com.apple.kernelcaches/ folder.

- Delete /System/Library/Extensions.mkext.

- Empty your trash. Reboot.

- Turn the AirPort back on.
