Aperture 4 is on it’s way?

Filed under: Uncategorized — devguydavid @ 4:41 am

Ultimately image quality is what is important to me in photography. Lightroom 3 beats Aperture 3 in my book for image quality, and I’ve spent a lot of time with both (about 6 months each), making comparisons, and deciding what looks best to me. Actually, throw Capture NX2 into the mix, because I spent about 6 months with that, too. But I really like the Aperture interface and “Apple ecosystem” integration, so I’d switch to Aperture if the image quality and tools were to be upgraded to match that of Lightroom.

So now I’m trying to decide whether I should upgrade to Lightroom 4, because it makes even more improvements in the image quality department. If figured, though, that I’d wait for a bit more to see if an Aperture 4 could sway me. In my search for clues, I just happened upon a book on Apple Aperture 4 that is due out July 4, 2012. Does this mean it’s actually on its way? Check it out:

Just in case they pull it:

Headphone Stand

Filed under: Do-It-Yourself, Music, Uncategorized — devguydavid @ 6:15 am

I wanted a headphone stand that was functional, was inexpensive, and somewhat matched the iMac black and silver theme.  I found this at Sears:

And guess what.  It was only $11.69.  It’s actually a banana hanger!  The headphones can rest on the banana hook on the front or on the top.  There’s also a hook on the back for the cord which was really for the included banana slicer.  That’s right, I got a headphone stand *and* a banana slicer. 😀

My First iOS App “Comparo”

Filed under: iOS, Photograpy, Products, Programming — devguydavid @ 4:04 am

I released my first iOS app.  It started as a project to simply learn about iOS development, but it has turned into a simple, straightforward utility that I believe is very useful for anyone with an iPhone or iPod touch that has a camera.  It is a utility that allows you to compare two pictures at once.  It provides up to seven such sets of pictures, and has functionality to associate a note with each set.  It’s great for comparing two cars at different car lots, or comparing your cabinets with the different floors available at the store, or whatever you want to compare!  Check it out at

Make your own White Noise Machine

Filed under: Do-It-Yourself — devguydavid @ 6:23 pm

One of our sons has a hard time sleeping.  We’ve tried lots of things.  He’s been through a sleep study, tonsils and adenoids were taken out, diet changes, etc.  Next on the list was white noise.  However, I didn’t want to spend the money on a white noise machine.  So I made my own, complete with a clock and an FM radio!

Snow Leopard TimeMachine Backups to an Ubuntu Linux Server

It works!  Perform this at your own risk; it’s unsupported.

First set up AFP:

Then make sure you enable using unsupported volumes:

Now add the new-in-10.6 plist: .  (This page actually has a script that sets things up for you; I haven’t tried it but it is a great idea.)

iPhone OS4 Revealed

Filed under: Apple — devguydavid @ 6:11 pm

“Multitasking, folders, enhanced mail, iBooks, enterprise, Game Kit, and iAd.”

As my friend Ben said, “multitasking and iAd are KILLER features.”  He’s right.  Unfortunately iPhone 3g and iPod Touch 2nd gen won’t get multitasking (and some other things).  I’m glad I spend the extra on the 3gs now!

Auto-bracketing with the Nikon D90

Filed under: Photograpy — devguydavid @ 8:26 am

Auto-bracketing is great for things like HDR, which I’d really like to get into more.  I don’t necessarily like when it’s “overdone” (although sometimes it turns out pretty neat from an art point of view), but I’m really into capturing more dynamic range to make the photo look more like what the eye can see.  Anyway, the D90 is capable of capturing three auto-bracketed frames at a time, and by default the photographer must press the shutter release once for each of those frames.  If you don’t have a remote this can be bad news as pressing the shutter release can move the camera and make it harder to align in post-processing.  However, I stumbled across a post that describes how to have the auto-bracketing happen with one press of the shutter release.  I’ve reproduced the steps here just in case that forum goes away:

1. Press the BKT button and set the bracketing to 3F by rotating the main command dial. Using the sub-command dial set the exposure increment to whatever you like. I prefer 1 stop intervals.

2. Go to CSM c3 Self-timer. Set the delay time, 5 seconds should be enough to allow the camera and tripod to stabilize. Next, set the number of shots to 3.

3. This step is optional. Go to CSM d6 and set the Continuous Low shooting speed to 4 fps.

4. Press the Release mode button and rotate the main command dial until the self-timer icon appears with the Continuous Low shooting icon above it.

5. Press the shutter release button. After the self-timer delay the camera will perform auto-bracketing with one push of the shutter release button.

Shadows Under Icons and Windows

Filed under: User Experience — devguydavid @ 7:20 pm

This is something that really annoys me, and Apple is doing it with the newly announced iPad.  But it’s something that happens pretty much everywhere (windows, mac os, gnome, kde, etc.).  If there were some configuration flag that turned it on or off as needed, then life would be grand.  What is it?

ssh keychain

Filed under: System Administration — devguydavid @ 10:30 pm

For the longest time I’ve maintained my own ssh-agent management scripts.  Every time I set up a new box I’ve had to go out and gather the information all over again.  But no more!

Vimperator and Gmail

Filed under: System Administration — devguydavid @ 8:28 pm

For a while now I’ve been tired of hitting ctrl-z every time I go to gmail to put vimperator into pass-through mode, and finally decided to see if anyone else had figured out a better way.  I found it. (more…)
