My audio samples are stored in a FireWire external drive for use with the MacBookPro. I am migrating everything over to the MacBookAir and Apple told me that there is no way to use FW drives natively. WTF?!
So now I am copying everything over to the new drive. Now there are many ways you can do that. You can use OSX’s native copy and paste. But OSX copy and paste is slow and would go do file counting. It also had issues if you terminate file transfers in the middle of it.
But rsync does all these—and better at it. It is already built in inside OSX. Shell tools are better and more efficient. You can buy apps which do these kinds of things but why buy crappy apps when you have the best tool for it?
Syntax:
$ rsync -av [source] [target]
or what I did in my shell:
$ rsync -av /Volumes/Ra/Audio/ /Volumes/LaCie/Audio/
where:
-a is a flag to tell rsync to turn on archive mode, where “accessed date” and “modified date” will not be modified as a result of copying.
-v is the flag for verbose mode, which shows the files being copied as the process continues.
For the rest of what rsync can do, look no further than its built-in manual, of course:
$ man rsync
I know, it's a no brainer. But I continue to be surprised at what most people didn't know is readily available in OSX

Part 1 of 3
This presentation briefly goes through the steps of how I processed a high dynamic range image of a cloudscape during stormy season in Hong Kong.
High dynamic range images or HDR, is the process of combining multiple low dynamic range captures into a single image, when a single capture does not afford the necessary range for what is intended.
Three captures were made for the making of the final image. All three images share the same ISO, the same aperture value, and the same focal length. They differ in shutter speed, and the result is shown here, with one normal exposure (0EV), one 3 stops down (-3EV) and one 3 stops up (+3EV).
The image on the left was exposed for the overall intent: the clouds and the reflection on the sea. The image in center was exposed for the highlights, which provides some tonal details in the sunlight in this case. And the image on the right is exposed for the shadow areas, where the buildings on the horizon are now correctly exposed, and you can see the patterns on the water surface.
After importing my RAW captures into Lightroom, I have exported them to merge to HDR via Photoshop. I used to use Photomatix for this but lately I have been using Photoshop because it was easier for my workflow.
The important bits to note here is that you should be focusing on extracting details from the captures, and not trying to create the final image.

Then I do the same for the water area. Note that at this point this image is very similar to by 0EV capture—no surprises there. This was what I saw when I photographed this photo. I do HDR not for effect, but just so that I can have some details on the shadow area.
At this point you see that really there is not much color to this scene. In fact, they stand to distract the overall image, so I removed it. Here since I have been working in Lab mode I just quickly removed the color channels or just removed the color saturation. If I work with images filled with color I usually would use the channel mixer in RGB mode or use the black and white tweaking modules inside Lightroom. But as you can see there is not much color in this image to start with so I can simply just remove the color saturation.
After importing back into Lightroom, I tweak things further as I feel that I can still get some more details in the shadow area. If I were inside Photoshop I would do a image-wide shadows/highlights tweak but since Lightroom version 4 there is this new Clarity parameter which works very well in manipulating local contrast so I used it.
And that’s it. But remember, every single image is different. This is not a recipes. There are no rules. Now go have some fun!
Cheers.

Data is important to me. Some humans commented that I have a lot of tags. If you have no data, sure, you don’t need tags. But if you have 10,000+ media items on Flickr like I do, you tag, you organize, you make sure that everything you do is searchable so that when someone asked you for a photo, you are able to find it under 10 seconds. I can do that. Can you?

1. I use Adobe Lightroom, because it has tight integration with the EXIF metadata storage scheme implemented by Flickr.
2. When I enter information in the title / description area of Lightroom, it automatically populates the relevant fields on Flickr. www.flickr.com/photos/seeminglee/8429087032/
3. When I assign keywords inside Lightroom, they get populated as Flickr tags. Lightroom has an awesome feature which allows you to create synonyms for tags, and is what I currently do for Chinese tags. I am bilingual, Flickr is not. So assigning synonyms inside Lightroom, I tag once but then Flickr shows both Chinese and English on the page. www.flickr.com/photos/seeminglee/8429087032/
4. The JPEG format stores metadata information in the form of EXIF. Add /meta to the Flickr URL and you see it instantly. JPEG EXIF on Flickr is text only, making it very indexable by search engines. All that info you spend time organizing in Lightroom is reflected automatically. www.flickr.com/photos/seeminglee/8429087032/meta
Some people said that they have no idea where I find the time to popular these fields. I don’t. Everything is automatic. Things just get smartly embedded everywhere. With a few scripts anything is possible.

Removing history does not work. Public unsearchability creates a false sense of safety. Just because you are not searchable by the public domain does not equate unsearchability.
Put yourself in the shoe of Google: if you just spend a whole lot of resources to dig up all these information, are you really going to disposed them all that easily? Most likely not. If I were Google, I will be happy to remove your result from the public domain to keep peace with you.
Tada! Due to quesiontable actions committed by you to fulfill your very desire to remove data, I have just identified why I get into the search business at the first place: to mine important intelligence data that no one else has a copy of. Thanks to your help, I have just identified what you considered to be most damaging to your credibility. I’m sure that businesses will pay me tons of money just to get their hands onto my treasure chest.

If Wikipedia:leet [1] is too difficult for you to comprehend, fear not—there is a simple English edition of the same entry [2] which can get you started in no time. 1337 is good for avoiding search engine index. But it has other good useful uses, such as creating highly memorable passwords which fits today’s strong passwords requirements.
Let’s say that I need to create a new password for pinterest, and I have decided to just use my name and pinterest for it so I will always remember it, so I type:
p1nt3r3stS33M1NGL33 (using pinterestseeminglee as my mnemonic key for human memory) by substituting all vowels with numbers and use my name in capital letters. Obviously you might want l create something stronger, for example:
P!n73re57533/\/\!n6733
Which is still basically “pinterestseeminglee” but easily memorizable. This beats using any other methods. Nerds tools are useful for something. Use it.

Before you decide to hack my pinterest account, let’s just say that this is not it—but now I could also be telling you this intentionally. What do you know? :)

Collusion is an experimental add-on for Firefox and allows you to see all the third parties that are tracking your movements across the Web. It will show, in real time, how that data creates a spider-web of interaction between companies and other trackers.

Part 2 of 3
By keeping everything in 16-bit color space we can manipulate the image further once we have all our materials together.
Most strange looking HDR images found on the web is a result of people exporting to JPEGs after this. But this image was not what I had in mind when I looked at the landscape, so let’s work on this further.
To further reveal details in the shadow, I created a curve which targets only the shadow area. Shown here in the layer blending options you can see that I have targeted the curve adjustment to only affect a graduated area. If I do not do this, the sunlight would have been over-exposed again.
Also note that I am using the Lab color mode inside Photoshop. This allows me to work with the luminance, or lightness, separated from the color a/b channels.
After I am satisfied with the shadow overall contrast, I work with the overall luminance contrast for the overall image. Obviously the curve shown here is specific to this image.
Now I created a layer mask with a basic gradient fill so I can use the curve to adjust the tonal contrast for the sky.
