Copying a DVD, CD, or Disk Image on OSX

There are a quite a few ways to backup DVD’s and other images using the GUI.  This one produces an identical digital image, including the boot camp partitions on a Snow Leopard DVD, of which I was making a backup copy.

Simple method to copy a data CD or DVD:

  1. Open Terminal (Applications>Utilities>Terminal)
  2. Check where the disk is mounted:  df
  3. Unmount the disk:  umount /dev/disk2s3
  4. Copy the disk to a file:  dd if=/dev/disk2s3 of=image-name.iso
  5. Burn using Disk Utility

/dev/disk2s3 is the device location df returned for my DVD drive
image-name.iso is the name of the iso image file that will be created.
Resulting image-name.iso is your CD/DVD image.

Have Technology, Will Travel

My international technical assignments often call for agility, fast response and high tech connectivity.  Actually I just travel for family visits a few times a year. =)  But still!  I turn to a kit of mobile gizmos that are a must for every road warrior geek.

  1. Air Power:  You need to write code (or watch sci-fi) without worrying about a laptop battery running out.  Mine is the Apple MagSafe Airline Adapter.

  2. Retractable Cables:  Ethernet, USB and Firewire.  When the hotel wireless is out or they are still in 1996 hard-wired land, your own compact cable can be a life saver.  Also helps when you have physical access to a WAP but not the wireless credentials.

  3. International  Adapters:  Laptops generally handle foreign power, so I’ve only ever needed the plug adapters and not the power adapters.

  4. External Hard Drive:  These are just too small and powerful to leave behind.  You can bring a system backup along, software you may need to install or a media library.

  5. USB Key Drive:  Same principle as above but for easy transfers of data, documents, wireless keys, etc.

  6. Wireless Router:  Ok, this sounds like a stretch but imagine a villa, hostel or cabin with one ethernet connection and many residents.  Allowing everyone online from anywhere is a big win since the average Linksys is only 2 pounds including the power adapter.  Since the actual electronics are  the size and weight of a cigarette pack, it seems like these should continue to get smaller and lighter.  You can skip the power adapter completely, via Power Over Ethernet.  Cisco already makes a 1 pound POE WAP for $100.  Not bad.

  7. Tethering:  Configuring your mobile phone to provide connectivity to your laptop gives you almost limitless connectivity.  No more airport and coffee shop charges.  No more PDA only access when stuck on the tarmac.

  9. Riedel Sommalier Wine Glasses and protective tote:  When the job is done, celebrate in style.  Ok, just kidding, but I did build this case for in-city transport!  =)

What am I missing?

WordPress UnGallery

The PHP gallery application used on my previous Web site, is now available as a WordPress extension plugin!  UnGallery dynamically imports a directory tree of images and embeds them into a WordPress Page.  The name describes the goal to stay out of your way and publish photos with no administration.

This approach allows your powerful administration tools like FTP, SCP, automation scripts or image editors to directly manage the content being published.  Changes are automatically seen in WordPress.  There are no web forms to select files for upload.  There is no importing or modifications to the database.  The gallery files are accessed remotely by WordPress and remain accessible and manageable, outside the WordPress environment.

If you’ve ever had to reorganize where your photos are stored, remove a few from a large set, or edit the red-eye of a dozen noticed after uploading, you know how inconvenient it is to return to the gallery management UI to update everything.  With UnGallery, all these add/remove/edit changes you make to your library are automatically rolled into the WordPress UnGallery view on the next browser load.

Features:

  • Unlimited depth, breadth, and number of photos. The gallery here has approx 8,000.
  • Multiple gallery views:  Top level marquee (optional), thumbnails, browsing previous and next pictures.
  • Gallery hierarchy breadcrumbs with links to parent, present, and sub-galleries
  • Photo library is managed outside of WordPress, simply update via FTP, SCP, etc.  UnGallery sees changes immediately.
  • Optional banner captions
  • Unbrowsable, private galleries
  • Thumbnail cache for faster page loads
  • Support for MP4 movies embedded within WordPress
  • Automatic image rotation of jpegs with exif orientation

To Do:

  • Make many of the setup options manageable on the plugin admin screen.  These include:  Thumbnail sizes, path to the gallery directories, caption text, and hidden text.
  • Optional caching
  • Move state, position handling to session
  • Fix MP4 case sensitivity
  • Allow other names than ‘gallery’ as the base URI / page name

Notes:

  • The default WordPress page width is a bit small for a gallery.  I use the excellent Atahualpa theme and increase the page width to a modern browser standard.  If you want to squeeze UnGallery into a small width WordPress install, you’ll want to update the width of the thumbnails it generates.  See the readme file.
  • This plugin is still young, so there will be things to fix.  Feel free to use it, extend it or contact me with questions.
  • Much is taken from other sources and noted inline.

Download:

  • Grab the current version at WordPress.org.
  • The installation steps are mostly standard, though there are couple simple, extra steps, noted in the instructions.

iPhone In Motion

The iPhone’s limited support for even basic animation and motion, especially online has been a challenge for years. This is the one feature that seems a natural fit for a media based smart phone. I’d grown dependent on these feature before migrating off my Blackberry PDA.

As a driver both on Austin’s streets and golf courses, I rely on doppler radar to monitor weather. It helps me avoid heavy rain, dangerous lightning, flash flooding, etc. My car feels the same about Texas’ Spring hail season. Unless you are a professional meteorologist, the single most useful datum regarding the threat of an inbound storm is the most recent doppler radar, in motion. There are a lot of 99¢ radar-in-motion apps on the App Store and some of them worked fine for me. But they mostly receive poor reviews, are often buggy and none are free. Also, the clearest, most useful images I’ve found are from KVUE’s weather site. The handy animated gif files published there are a simple way to track the direction of storms, but not with an iPhone.

Enter iPhoneInMotion.com, where I’ll animate useful content that is not available for the iPhone. Apple’s support for animated gif files, AVIs, mpegs, etc may be forthcoming, but until then, this can help keep you advised of your current weather activity.

Technology Information?

If you haven’t heard the term before, don’t worry. Here are the details of my consulting services, which I call Technology Information.

I’ve worked closely with Information Technology my entire career and it’s been an exciting one. One of the benefits afforded to IT engineers is the days are rarely dull or repetitive. The scope of work interacts regularly with all parts of company operation from Sales to Marketing to Engineering. In addition to the expected responsibilities like keeping the servers online, I’ve had the opportunity to contribute web content, product documentation, marketing collateral, online help systems, blogs articles and knowledge bases.

Today, I use my Information Technology background to provide Technology Information services. I help companies build white papers, product documentation and strategic messaging for their Web sites. I advise merchants on site design, eCommerce solutions and deploy content management systems. I’m a technical writer experienced working with Development groups, Support teams, Marketing and Sales organizations and business owners. My focus is on creating written technology content, but I have a strong background in the associated technical systems involved as well.

I recently worked with RED Method, a local user interface design firm located in Austin, Texas. RED works with companies like yours, from startups to the Fortune 50, expanding business opportunities by rapidly turning product ideas into market validated software applications. I helped RED deliver the strategic messaging and case studies for the launch of their sharp, new Web site. Check it out!

I also worked with RSH Garage Doors to launch their new Web site. RSH’s owner, Bobby Halliwill wanted a clear and elegant design to deliver the RSH message of service and value.  He also had a business to run, so it was important he receive a turnkey solution including: hosting, domain name administration and content management. I worked with RSH to create and launch a new web site, on schedule.
