BLACKSMITH_TB  Not so much - Wireshark isn't a port scanner, instead it captures traffic by protocol. But as other posters are quick to point out, there are lots of free port scanners for OS X, too.  
(Version 3.7.2)

BLACKSMITH_TB  The color palette of the original was taken from a Jackson Pollack painting, titled Shimmering Substance.  
(Version 1.0.1)

BLACKSMITH_TB  I've tried downloading the 1.0.2 plugin from three different places, but they seem to install the 0.86 version of the plugin. Am I missing something?  
(Version 1.0.2)

BLACKSMITH_TB  Especially nice on dual monitors, as the two cityscapes are subtly different.  
(Version 1.1)

BLACKSMITH_TB  While there's no doubt that the Windows versions of RealPlayer have been larded with adware/spyware for years now, the OS X and Linux versions are largely benign. Of course, I don't think anyone would bother installing RealPlayerif it weren't for the occasional annoying site that insists on using RealAudio for its content...  
(Version 11.1)

BLACKSMITH_TB  I disagree completely. I know it's possible to have a Bad Experience™ when trying to upgrade to some of the newer betas from an old version (completely uninstalling, deleting prefs, etc. may be necessary). But there's no doubt that the new community-maintained builds are more stable, and have a much smaller memory footprint than the old versions. I've been using 1.0b56a7 since it came out at the beginning of the summer, on 10.5 and 10.6, with no problems whatsoever.  
(Version 1.0b56a7)

BLACKSMITH_TB  If you have 1.7 installed, doing a

sudo port selfupdate

Should update for you (it does for me on 10.5.8, at least).  
(Version 1.8)

BLACKSMITH_TB  While it's in beta (at least through August) the license is $29, with an option to buy a lifetime license for $49, afterwards that will be $39/$54 apparently. I like PB a lot, so I coughed up the $29, but $50 is just too much to pay for an email client. I may regret that eventually, of course...  
(Version 1.0b15)

BLACKSMITH_TB  It will allow you to send any audio to your Airport Express, but it introduces about a two-second lag. For watching DVDs, or avis, etc., VLC solves this problem by allowing you to shift the audio (intended to compensate for bad dubbing, I think, but it works perfectly with Airfoil).   
(Version 3.3.2)

BLACKSMITH_TB  This is good in theory, but in practice, Quit refuses to quit anything I've tried (on 10.4.11). Neither the -a or -p flags seems to have any effect - I consistently get:

43:166: execution error: System Events got an error: Can't make every application process whose name = "Adium" or short name = "Adium" or title = "Adium" or displayed name = "Adium" into type reference. (-1700)

No running application matches "Adium"  
(Version 1.0)

BLACKSMITH_TB  Obviously, developing a useful and interesting app takes significant time and energy. And it's great to see developers get compensated for their work. Software is like any other product - prices are what the market will bear. I buy a fair amount of shareware personally, but I couldn't justify spending nearly $100 on a snazzy drawing program. So I'd rephrase this as "you might sell many more copies at a lower price."  
(Version 1.3.3)

BLACKSMITH_TB  The all-new (Leopard or better) GeekTool 3 is in beta:

http://thememymac.com/2009/geektool/more-on-geektool-3/  
(Version 2.1.2)

BLACKSMITH_TB  As the App's icon suggests, I assume the intended audience are web developers and graphic designers who need to create placeholder text. It does seem a little like overkill, since there are plenty of lorem ipsum generators, like lipsum.com.  
(Version 1.0 build 7)

BLACKSMITH_TB  It is a firewall. It's designed to interfere with network traffic. Without creating rules to allow EyeTV access to the internet (including checking for updates, etc.), LS would in fact stop it from working.  
(Version 2.1.1)

BLACKSMITH_TB  Odd that an anonymous poster would know the product history of the non-free competitor, No Spin. While it's theoretically possible they're a user who has installed multiple versions, I'd say it seems much more likely they're associated with No Spin's author(s), making this hardly an impartial review.  
(Version 1.0)

BLACKSMITH_TB  Once you've installed, you can do

fing -h

for a list of options. It has a friendly interactive mode,

fing --interactive

Generally speaking, you'll need to sudo fing.  
(Version 1.2)

BLACKSMITH_TB  S3 isn't free, but it's cheap:

http://aws.amazon.com/s3/#pricing

You do need some sort of interface to it, hence JungleDisk.

JungleDisk is a one-time price, after which I believe all upgrades are free, and the license is good for OS X, Linux, and Windows versions:

https://www.jungledisk.com/desktop/faq.aspx

I'd say the MobileMe appears slightly less appealing as a backup solution, but it does offer other functionality (syncing mail, calendars, etc.). They're really not too similar.   
(Version 2.60a)

BLACKSMITH_TB  It's maddening that these Quicktime updates and patches require a restart. Just how many low-level hooks does it have into the OS?  
(Version )

BLACKSMITH_TB  Keep in mind that you have to manually enable the Tracemonkey engine, by going to about:config and searching for the javascript.options.jit.content pref. Set it to true.

Gmail screams, I have to say.  
(Version 3.1b1)

BLACKSMITH_TB  FAT32 limits maximum file size to 2Gb, which makes moving large files (VMs, .iso, etc.) rather inconvenient.  
(Version 1.2812)

BLACKSMITH_TB  To get the beta version, you'll want to go to Opera.com, as the Download Now links are both to the current stable version.  
(Version 9.5b2)

BLACKSMITH_TB  Not true. Try File > Convert Files... in Max, which can convert from any of the many formats it supports, to any of them.  
(Version 1.0)

BLACKSMITH_TB  In fact, Real have made their codecs available for years via the Helix project: https://community.helixcommunity.org/realcodecs/

And they've also been reverse-engineered by the Real Alternative folks (for Win32, at least).

So it would be perfectly reasonable to include Real support in VisualHub.  
(Version 1.31a)

BLACKSMITH_TB  It may well run under Tiger (10.4.11 in my case), but the .pkg refuses to install.  
(Version 0.11.3)

BLACKSMITH_TB  We're spoiled for choice when it comes to standards-compliant browsers, no doubt. Firefox is my fave because of the many extensions available, but they do tend to slow it down. For those who don't need the added functionality they offer (development tools, content blocking, etc.), Safari and Opera are great (and fast) choices.  
(Version 2.0.0.11)

BLACKSMITH_TB  Oops - copy and paste error - you need the leading slash, of course:

/Applications/rr.app/Contents/MacOS/rr -window -hires

Hi-res is nice, too.  
(Version 0.23.3)

BLACKSMITH_TB  Looks like this option is now available if you invoke rr from the command line:

Applications/rr.app/Contents/MacOS/rr -window

See the developer's page for other flags.  
(Version 0.23.3)

BLACKSMITH_TB  I see it adds Vista-related features along with (finally) being a universal binary. But it has a bigger footprint than CORD (40M/400M for RDC vs. 20M/200M for CORD on my iMac). I think I'll pass.  
(Version 2.0b1)

BLACKSMITH_TB  You shouldn't have to reinstall (which may not fix things in Application Support anyhow). Just run FF in Safe Mode:

http://kb.mozillazine.org/Safe_mode  
(Version 1.2)

BLACKSMITH_TB  I'm not sure you could call all linuxes "difficult" (ubuntu anyone?), especially if you choose to boot a Parallels VM from a live cd iso.  
(Version 2.5.3170)

BLACKSMITH_TB  While the Unarchiver is very, very nice, it can't handle .sitx archives, so it's a chicken-and-egg problem. When people stop using Stuffit to compress files, there will be no need to use Stuffit to decompress them.  
(Version 11.0.1)

BLACKSMITH_TB  It's a little unclear why you'd want to do a fresh full backup with Superduper after defragging - the copy on the external drive shouldn't be fragmented. Superduper isn't doing some low-level snapshot of the original - it's copying files over sequentially, so they shouldn't be fragmented at all. This thread has details:
