Review: Seattle Sports Dry Doc Waterproof Digi Case for my iPhone

Jen Wieczner told a story of a friend lost, perhaps but for the sake of a waterproof phone case ...

When Technology Can't Save You - Jen Wieczner - Technology - The Atlantic

... four others, including my friend Tyler Lorenzi, 23, treaded water while the river swept them downstream. Around the same time their fellow sailors were pleading at the door of a strange residence, a tugboat found their overturned vessel and called authorities. Near a ship graveyard known as the Ghost Fleet, Tyler was eventually pulled unconscious from the James; he passed away in the hospital. Another sailor, Alexander Brown, 24, drowned. Tyler, a graduate of Northwestern University, worked as a research engineer for the National Institute of Aerospace, a division of NASA; Alex was earning a doctorate in engineering there.

I didn't know Alex, but Tyler was generous, selfless and warm, and gave hugs without hesitation ... He was dashingly handsome, strong in the way of someone who got that way by going about his regular business, with perpetually tan skin and flushed cheeks, the kind that mark someone who is comfortable outdoors and spends much of his time there...

... According to the Virginia Marine Resources Commission, which investigated the accident, none of the boaters were carrying cell phones on the fatal night, or at least none that still worked. After Tyler's death, I wondered about what went through the boaters' minds -- tech-savvy young people who worked and studied at NASA programs -- when they fell into the water: Did they immediately realize the gravity of the situation? Dependent on their technology on land, did they reach automatically for their phone before reality settled in? What must it have been like to realize that their means of communication - and hopes of rescue -- were quite literally dead in the water?

... Motorola calls its Defy SmartPhone "life-proof," because it's water- and dust-resistant; its new Brute flip phone is designed to meet military standards for "extreme elements," including "blowing rain," "salt fog" and liquid immersion. RIM, which manufactures Blackberry devices, says, "While it is possible that BlackBerry could work after being submerged in water, RIM does not recommend doing it," and adds that in a recent Yahoo News water test, BlackBerry did just fine.

Needless to say, iPhones are not water resistant. They are notoriously water sensitive [1].

You can, however, buy pouches for $10-$25 that will keep the phone working underwater. You can even use the phone in the pouch.

I tested a cheap one at home. Here's my Amazon review ...

Amazon.com: John Faughnan "John G Faughnan"'s review of Seattle Sports Dry Doc Waterproof Digi 02 ...: ""

I purchased and tested the Seattle Sports Dry Doc Digi Case. The Digi Case 02 appears to be the same case with different attachment device.

I filled the case with a paper towel and then submerged it for 30 minutes in 1 foot of water. The end of the paper towel was slightly moist when I recovered. Most phones, even an iPhone, would probably still be ok at that point.

It looks to me like a new Digi Case, carefully sealed, would protect against a quick dunk. This one is fine for keeping my phone in a non-waterproof bike bag or for insurance on a hiking trip that could involve a stream crossing. I would want something more robust (and more costly) if I were going on a canoe trip.

An iPhone is useable through the case -- the touch controls work.

For an iPhone 4 to fit best, it's probably worth removing any other case. Larger pouches work with a case on the phone.

[1] We inherited a friend's iPhone 1 after it visited a white porcelain bowl. It worked well as an iTouch for my son, save for the lack of a speaker. One day, after about 1-2 years of use, the external speaker started working. I do not understand this.

Lessons from sharing our team videos

In a burst of foolish optimism, I volunteered to do some videos of our team pitchers and share them.

This turned out to be much harder than I imagined. It's one of those tasks where each step has multiple options, but only a few choices really work.

Along the way I tested and abandoned MobileMe's video gallery [1] and Karelia Sandvox [2]. I briefly considered then discarded Picasa Web album video sharing.

I did figure out a path that works. Two of 'em actually. I'll share the easy one first.

The easy option

Use an iPhone. Take short clips. Don't edit. Upload. Share links.

The much more painful deluxe option

The deluxe option assembling multiple video fragments from a Canon dLSR HD video camera into a one video for each pitcher, then embedding them in a web page.

If I ever do this again, this is what I'll do for the deluxe option.

I. Getting the video

  1. Bring a tripod (!) and an external microphone.
  2. Have the coach use the external microphone to narrate comments.

II. Use iMovie and share via YouTube hidden links

This was the first time I used the new iMovie. I read a few pages in the surprisingly well done Portable Genius Guide to iLife (see [3]).

  1. Each player gets one Project/Movie.
  2. Edit in 3:4 ratio -- this is the pitcher we're working on.
  3. From iMovie share to YouTube as "private" at the highest available resolution.
  4. In YouTube change these to "hidden".

This is time consuming. It took about 10 minutes for each clip to create a movie and upload. An alternative would be to export as .mp4 (NOT default .m4v) then bulk upload overnight [4]

III. Share images using Blogger and MarsEdit or HTML markup

  1. I tried a few web page editors, but, as noted above, I didn't have much luck.
  2. Instead I used YouTube's embed code (iframe markup) and pasted the embed text into the MarsEdit HTML view for each video. It was tedious but gave good results.

- fn -

[1] I'd not tried it before. Now I see why Apple gave up on the Galleries.
[2] Crashed on me during my video uploading attempts. Could be just bad luck -- pretty much every OS X app I use crashes sooner or later. Almost like 10.6.7 is an unhappy host OS. Still, bad timing.
[3] iMovie notes

  • Clip Library is a pool of shared clips that can be included by reference in multiple Projects (movies). Clips can be stored in iPhoto, Aperture 3+ or iMovie. I think Clip processing is smoothest if they live in iMovie. Clips can be split, reorganized, rated, merged. Even deleted, though that's not obvious.
  • A "project" is a movie.
  • In a clip or a project/movie click to set start point, space to play
  • click then drag to create a frame within a single clip (can't span clip): Click into  this frame and drag and drop to the Project area. It took me forever to understand this. I kept thinking I had to edit the clip first.
  • Native export is .m4v -> evil, vile, worthless, foul spawn of satan. Want .mp4

[4] The settings to make this work are not obvious. I got decent results when I used Export to Quicktime, MP4, then set data rate to 4096, image size 768x576, Fit within size for crop, and "best quality" encoding mode in video options.

The unremarked defects of Apple's newer iPhone cables

I've not seen this mentioned anywhere. Time to remedy that.

We have a collection of about 8 iPhone/iPod USB cables. The older ones locked onto devices. The newer ones have friction locks.

All of the old ones are in great shape.

Two of the three newer ones are damaged. The cables separate from the connectors at both ends.

Clearly, something went wrong. Looks like a manufacturing defect.

I wonder if it's fixed with newer cables.

Why I hate video: Format, codecs, DRM and m4v vs mp4

My version of iMovie exports (09), by default, .m4v. (emphases mine)

The M4V file format is a video file format developed by Apple and is very close to MP4 format. The differences are the optional Apple's DRM copyright protection, and the treatment of AC3 (Dolby Digital) audio which is not standardized for MP4 container.

Google's Picasa service doesn't support .m4v ...

Video Upload Requirements : Video - Picasa Help:

... Uploadable Video File Types .3gp, .avi, .asf, .mov, .wmv, .mpg, .mp4, .m2t, .mmv, .m2ts ...

Neither does YouTube ...

Supported YouTube file formats - YouTube Help

WebM files - Vp8 video codec and Vorbis Audio codecs

.MPEG4, 3GPP and MOV files - Typically supporting h264, mpeg4 video codecs, and AAC audio codec

.AVI - Many cameras output this format - typically the video codec is MJPEG and audio is PCM

.MPEGPS - Typically supporting MPEG2 video codec and MP2 audio

.WMV

.FLV - Adobe-FLV1 video codec, MP3 audio

Heavens, but I do hate video data standard issues.

It's the patents, it's the DRM, and above all, it's Apple. Data formats and DRM are at the core of Apple's great flaw -- a deep addiction to data lock [1].

[1] Pro video customers of Apple's Final Cut Pro are learning all about what Apple's data lock means.

Update 7/5/11: Two wikipedia articles on Apple's ProRes 422 and ProRes 4444 and these additional articles help capture the full horror of the 2011 state of video codecs -- and the complexity of the video editing workflow. There is nothing analogous to JPEG or even JPEG 2000. See also ...

FCP X didn't add anything new to ProRes (mercifully). It will do "native editing" on h.264, which sounds interesting.

Karelia Sandvox fails

I've been looking for a general purpose personal OS X website creation tool for years, ever since FrontPage effectively expired @2000. iWeb was a feeble contender but it died a year ago.

Yes, this is a terrible market.

My most recent trial was Karelia's Sandvox; I tested an earlier version in 2006.

Sandvox looked like a contender. It's been around for years and is being actively updated. It has a trial version.

It failed under 10.6.7. It had several weaknesses and one fatal error. The weaknesses were that it uses a proprietary database store (no native HTML edit) and that when I searched help and the web for "embed video" and MobileMe I found nothing.

The fatal error was that it crashed when uploading a page with several embedded videos to MobileMe. I got a classic "quit unexpectedly" dialog.

There's not much going on in this corner of the tech world. Anyone have something that works?

Google Plus Circles don't have readable feeds

File this one under ominous -- Google Reader can't handle Google Plus feeds.

You can see this with Andy Hertzfeld's "public circle":

https://plus.google.com/u/0/117840649766034848455/posts

Google Reader can't find the feed. I thought the https was the problem, GR can't do authenticated feeds. So I tried Safari.

Safari does treat the "circle" as a feed, but the post list it shows doesn't match what we see in the web UI.

My web searches didn't turn up anything on this, which is kind of interesting too. It's not subtle!

OmniDiskSweeper finds 247GB in my OS X Volumes directory (Aka: Disappearing drive space)

OmniDiskSweeper is a free utility from the superb OMNI group. I run it periodically. Today it showed me:

  • 1Password is storing 177MB of 1Password backups in Library\Application Support.
  • All my iPod and iOS backups come to 2.1 GB. That's a lot, but not bad for five iPhones and a few iPods (who uses iPods any more?)
  • iPhone software adds up to 1.6 GB (3.1, 2.1, 1.2, 1.1)
  • Caches runs 1.7 GB
  • ITunes Library has swollen to 70GB, mostly due to movies
  • Pictures (Aperture, iPhoto) runs to 80 GB
  • I had 500MB of tunes in Music\Amazon MP3 that were also in iTunes. Not sure how that happened, but obviously I don't need both.
  • I had FileMaker Pro 8 (!) installed once in my Applications folder and once in shared applications
  • Volumes, a "hidden" root unix directory, had 247GB in it. [1]

I freed up a GB or so in minor cleanup, but then I had to decide what to do with Volumes. I'm used to Volumes holding Unix aliases, not folders.

Volumes held two folders named after my Time Capsule backups. One held 227 GB, the other a mere 41GB. They were both created within one day of one another in Jan 2011. The smaller one is a copy of a portion of my drive, the bigger one was the entire drive.

Google couldn't explain these findings, but I found this one reference that sounded interesting ...

Another tip is to look in your /Volumes directory. I once found 100's of megabytes there. It seemed to be a mirror of what had been on a firewire drive that had been unplugged before ejecting. Some program had tried to write to '/Volumes/FireWire/data/'. However since the firewire drive had been removed suddenly, it just created a directory called FireWire/data and wrote it there...

Except I didn't find 100s of MBs, I found 100s of GBs. I am pretty sure Time Machine put them there, and I wonder if it had to do with Time Capsule being offline.

After due consideration I deleted these 600,000+ files. I do, after all, have redundant offsite backups in addition to Time Machine.

[1] You can view it in Terminal, but it's easiest to use the Finder's "Go to Folder" feature and just enter "Volumes".

See also:

Update 6/25/11: Through an Apple Support Group discussions I learned that this isn't terribly rare, and that it's particularly seen with disk cloning software -- probably because of the volume of data they manage. It smells like a deep OS bug -- the OS loses the connection to the "virtual" target in /Volumes and starts writing to the local disk. I wonder if this is more common in 10.6. I am surprised I didn't find more about this on Google, perhaps this post will help. Through the discussion thread I learned of these posts ...

  • Tiger Problems - Disappearing file space: Francine Schwieder wrote this several years ago, but I believe it's all still true. Suggests this is not a new OS X problem.
  • TidBITS Adam Engst: Dealing with Doppelganger Folders in /Volumes: Adam wrote this in 2008. He ran into trouble when using Crashplan ... 
    ... Needless to say, applications should notice the disappearance of a disk, and Matthew Dornquast of Code42 Software said that they had spent nearly 100 hours trying to prevent CrashPlan from writing to a folder in /Volumes if the disk disappeared. However, I received reports of a wide variety of applications suffering from this problem, including the BitTorrent client Azureus, the Perforce version control system, Apple's Xcode development environment, and Mac OS X itself...

    ... More generally, this is an architectural problem in Mac OS X that Apple needs to fix. Although applications bear some responsibility for creating folders in /Volumes when they shouldn't, the operating system should protect itself from such an obvious misuse. Unfortunately, a vast amount of code, both from Apple and other developers, assumes that /Volumes is writable, which means that fixing the problem would require lots of other changes, and Apple hasn't had the fortitude to force such an unpalatable solution on developers....
  • Apple Tips Where did my Disk Space go?: James Pond on multiple causes of disk space loss, including the /Volumes bug.

I've suggested that Onyx add a check for these files in its cleanup process.
