Did either one of you login to amazon, Facebook, google, etc on one of the other persons device? If so there is likely still a tracking cookie associating you with her device. And your searches are causing her device to be targeted.


You are logged in to Android phones all the time. Not that it matters since they know who owns the phone.


Even if you don't have cookies enabled, then browser fingerprinting could make the connection.


How much data has Google and Apple collected using LIDAR and such on their mapping/street view vehicles?


It's in the millions. Tesla's is in the hundreds of millions/close to a billion.


Technically, it's 0, because Tesla does not use LIDAR at all.


Additionally you could decide to only store up to 6 occurrences of each integer in the bit array, use the value of 7 as an indicator that there are 7 or more occurrences and store the actual counts for those cases in a sorted array occupied by the remaining 346 bytes left in the 4KB page.


The other challenge is developing for all the variants on Android (OS version, different manufacture idiosyncrasies, hardware speeds, screen resolutions, orientation, virtual vs hardware keyboard) all increase the development time and especially the QA time on Android.


Any opinions on pros/cons of using Varnish vs a CDN (Akamai/Limelight)


On small projects where one has complete ownership and knowledge of the code, one can get by without testing. When you have a large project with tens to hundreds of developers, automated testing gives the developers the confidence and comfort to make large or deep changes with an accurate measure as to the overall stability of the product, even the areas where an individual developer may have little domain knowledge of.


Agreed. I submitted a couple of patches to Rails recently and I would have been far more reluctant to try to make fixes if I hadn't been able to verify them with a fairly extensive test suite.

People get too dogmatic about testing and particular testing methodologies but testing in general is a very powerful and useful tool when used wisely.

DPI is a pointless term in comparing different medium. One of the comments mentions Dots per Radian of viewing angle which I think makes much more sense. Don't need/want my TV to have 300DPI, but 30 DPI would actually be pretty awesome there.


Indeed. Any medium (regardless of dot size) will appear razor sharp when viewed from far enough (so that one can't see individual dots).

Of course, if there are enough dots in particular physical area, the human eye is incapable to see a single dot from the closest possible focusing distance. This is what I would call a "retinal diplay". Not sure if 326 DPI is enough for that, but is surely enough for the iPhone's screen.

W3C recommends the pixel to be interpreted as about 4E-4 radians[1]. Personally I think that's a stupid idea, and I don't think anyone has implemented it, but I would support using such a measure for device resolutions.

I believe the biggest reason android adoption is so high is the availability of android devices on all major US carriers as opposed to the iPhone being an AT&T exclusive.


Up until this point at least, I think you're correct. I certainly would have liked to have purchased an iPhone since long before Android was ever released, but AT&T's reception in my area is abysmal.

However, even if Apple can get out of their exclusive arrangement with AT&T, it may be too little too late.
