cjdavis··on Galaxy Nexus Power Analysis: Why chargers can't keep up with navigation
IEC 62684, Interoperability specifications of common external power supply (EPS) for use with data-enabled mobile telephones, is an international standard - and is basically micro USB. Even Apple is supporting it.

Some quick looking doesn't show any details of the max power rating unless you buy a copy of the spec for 45 Swiss francs.

cjdavis··on AT&T Drops T-Mobile USA Deal
The more accurate term would be Too Big To LET Fail * , but the acronym starts getting unwieldy.

* [Or The #### Will Really Hit The Fan]

cjdavis··on AT&T Drops T-Mobile USA Deal
You can actually buy the iPhone 4s unlocked straight from the Apple website. I just did last week as an xmas gift for my dad, with the intention of trying it out with his current account on Cincinnati Bell Wireless.

I believe they use the same frequencies as T-Mobile.

cjdavis··on Amazon Puts Your $1000 Kindle Library 'On Hold,' Apologizes, Shrugs
The letter clearly states he has contacted every Amazon support option he knows of:

  I have filed a complaint with the BBB, emailed everyone I
  could at Amazon, called the Customer Service Line, the
  Kindle "Executive" support line, and Corporate. I have 
  been apologized to by everyone I have spoken to and been 
  told that they have never seen this situation before.
 
  None of them can tell me if I will ever receive the 
  content I have paid for.
cjdavis··on We Are All Criminals – or – Why I Hate Traffic Cops
His first population based result - "If each <truly awful crime> had one perpetrator we’d be talking about 3.3% of the population" - uses the correct population. After that he's using 208.
cjdavis··on Adobe Donates Flex to Apache
It's not necessarily a security issue. There are many custom corporate apps that only run on IE6.
cjdavis··on Skyim breaking Steam record -- a singleplayer game has 240,000 users online
Wow, Counter-Strike is still number three, over ELEVEN years after release?!
cjdavis··on Apple: Siri Only Works On iPhone 4S, We Have No Plans To Support Older Devices
The carrier paid for it. They want you to sign up for a contract extension to get the shiny new phone. They have no interest in supporting your old phone.
cjdavis··on Amateur rocket launch reaches 121,000 feet
We used shiftbrites in our 7x8 window at Hive13 adnd it worked out very nicely. Last week we got it working with OSC and Processing - http://www.hive13.org/?p=527 - which should make connecting to it with a wide variety of software pretty easy.
cjdavis··on Google Reader cutting internal social features, integrating into Google+
They are already adding it to the export function - hooray, because I was sorely missing this in the split of my regular Google account from my GA account. The third paragraph reads:

   We think the end result is better than what's available today, 
   and you can sign up for Google+ right now to start prepping 
   Reader-specific circles. We recognize, however, that some of you 
   may feel like the product is no longer for you. That's why we 
   will also be extending Reader's subscription export feature to 
   include the following items. Your data belongs to you, after all, 
   and we want to make sure you can take it with you.

   * Your subscriptions
   * Your shared items
   * Your friends
   * Your likes
   * Your starred items
cjdavis··on Smartphones' accelerometer can track strokes on nearby keyboards
Ignoring the security implications, this could be a great way to use an old spare keyboard for text entry on your phone. And with some training, it would probably be far more than 80% accurate.
cjdavis··on Don't confuse it with Quickster, QuickStar, Quik-Star, Kwik Star, or Kwikster.
Netflix is well known for its amazing delivery system, and this new name emphasizes that - not what product is being delivered at all. I think Qwikster will be expanding into shipment of all sorts of non DVD movie type things. They are already going to be doing video games.

That said, yes Qwikster sounds stupid. But the same could be said for such words as Google, iPad, etc.

cjdavis··on Hacker group draws increased scrutiny from feds
This is as likely and will be taken as seriously as the possibility of addressing the grievances of the people that committed 9/11.

To continue the over-generalization - that Anonymous has not (yet) claimed responsibility for any violent acts is the only thing separating the two in the eyes of the government (and the general public.)

cjdavis··on Vim Cheat Sheet - For Programmers By Programmers
I remember the old joke of emacs standing for Eight Megabytes (of RAM) And Constantly Swapping. Oh for the days when that was a lot of system memory.. Not really.
cjdavis··on Iran forged the wrong SSL certificate
Or so you think - as the parent says, it just takes a DNS entry to make somebody else's server appear to be yours.
cjdavis··on Dead Man's Switch
Here's how it would work: You decide how many different friends and family you are going to send your secret message to, and how many of them will need to agree to unlock the message together. Let's say you pick 15 recipients and 8 need to agree. Then ANY 8 of the 15 messages can be combined to decrypt the secret.

No 3rd party service needed at all.

Couldn't you encrypt the results again with different numbers? So you could do interesting things like 'my wife AND (any 3 of 50 others)'

cjdavis··on Groupon has no viable business model
I'm not sure, but it could be that you are paying actual hard cash - much like a gift card. In many states it is illegal for gift cards to expire.
cjdavis··on Philips LED bulb Tear-down
Meanwhile the >75% reduction in power usage and >800% increase in lifetime are features that have surpassed the incumbent (which are what makes the $40 cost affordable - a feature they are no where near approaching..)
cjdavis··on How 38 Monks Took on the Funeral Cartel and Won
How can they be amazingly competitive industries AND have amazingly high margins at the same time? I thought those were mutually exclusive things.
cjdavis··on Show HN: My weekend project, QR-codes for everybody
At Hive13, we are putting QR codes on equipment description pages using a wiki template - http://wiki.hive13.org/Equipment. Our next step is to print the template info to a sticker, which is placed on the equipment described. Then you have an easy link using your phone to further information directly on the tool itself.
cjdavis··on Coming soon: make your phone your wallet
This is a specific use case for NFC, in exactly the way you describe. NFC should be usable for pairing in Bluetooth v2.1.
cjdavis··on Open Source 5-Axis CNC mill and plasma cutter
Something of this size and cost is perfect for many local hackerspaces to build and operate.
cjdavis··on 20 Million-Dollar Businesses You've Never Heard Of
Yes, that's a gallery where the text is not overlaid on the photo, and the Google ads are not quite as tacky, but I think this is missing the point: the content in the OP doesn't belong in a photo gallery format at all.

Notice how many points the posts summarizing the article received - NOBODY to whom you actually want to advertise has any desire to sit around clicking through a gallery to read text.

cjdavis··on Drupal 7 Released
I'll second this. Drupal Gardens is well worth checking out, especially if you are new to Drupal. You can get a site up and running _very_ quickly, the built in theme editor is amazing (think Firebug with a save button), and you really can get a tarball of the whole site with a couple of clicks.

I build Drupal based websites, but I'm not affiliated with Acquia.

cjdavis··on A Typical Day for PFC Bradley Manning
"The guards are required to check on PFC Manning every five minutes by asking him if he is okay. PFC Manning is required to respond in some affirmative manner. At night, if the guards cannot see PFC Manning clearly, because he has a blanket over his head or is curled up towards the wall, they will wake him in order to ensure he is okay."

Just went looking for this and couldn't find anything. Pointers?
cjdavis··on Check if your email is amongst those compromised in Gawker break-in
It is very, very easy. The first 8 characters of your password were hashed using DES without a salt. Your cell phone has enough CPU to crack them all.
cjdavis··on Startup Lessons, Courtesy of United Airlines’ Crappy Customer Service
No, it's because airline ticket pricing is simply based on the maximum amount of money they can get out of you. Some examples:

A one way ticket nearly always costs more than half the amount of a round trip ticket. So to prevent people from using one half of a round trip, they cancel your entire ticket.

Even better: when Delta had a huge hub here in Cincinnati, they owned something like 80 - 90% of the flights at the airport. They jacked the prices up to the point this was the most expensive destination in the country. However flights out of the Dayton airport 50 miles away were $100s cheaper - including on Delta. And the Delta flight would connect in Cincinnati! When I asked what would happen if I just flew out of Cincinnati and ignored the Dayton - Cincy leg, I was told they would cancel the entire ticket. Same thinking as the first example.

A study at one point showed something like 1,500+ people a day were flying out of Dayton rather than Cincinnati because of the cost difference. While the lost jobs hurt when Delta merged with Northwest and pretty much moved their hub away, I was happy to see them go.
