I don't know how to respond, we are talking past each other ,,, sorry I brought the topic up!
But, the example I gave was a multi-demensional array of n records -- each record had 4 fields.The difference in XML is that each field of each record would be enclosed within tags like:•quantity>3•/quantity>•name>Item 1•/name>•price>3.23•/price>•special>•/special>• used in place of < open tag symbolthis record contains 11 characters of actual data and 72 characters of superfluous XML tags.repeat n times for an array of n recordsThe point is that the format of the data...
I agree that they are used for different purposes.But, I think ubiquity and universal availability of XML parsers has made programmers lazy. When you write an app, you decide on the format and content of your data pretty early in the design cycle. After that, it changes infrequently -- say, a new version of the app with additional records and fields.But, every time anyone uses the app they are spending an enormous amount of overhead for the luxury of using XML.In my...
Yeah! A hash, used properly, can be a very efficient way to store and manipulate (retrieve, process, scale, distribute) data.The keys should be few, meaningful and unique.The values should be concise and encoded for their primary usage (streaming, query, transactions, etc.).... And, of course a value can always contain additional hashes  
Ya' know ...IMO, one of the biggest wastes in iOS and OS X is the system-wide use of XML. It wastes bandwidth, processing time, storage, cell data, RAM and battery power.For example. I have a small iPhone data source that I use to prime a table on the iPhone and Watch. If stored as a PList or archive file, it is encoded into XML, stored within the app on disk/SSD, decoded from XML into RAM, then processed.The XML packet is twice the size of a text representation of the...
Well ... You are right! In truth, the top of the edges, themselves, aren't touch sensitive ... but if you just broadly aim for an edge from the front, with your finger at an angle (~ 45 degrees) you'll hit the edge of the screen without obscuring anything but the very edge ...Like the old story of the contest between the mathematician and the engineer -- it's close enough to get the job done Edit: I am fiddling with a Watch app I wrote, that shows a table of 23 rows, 3...
You don't need to pinch the digital crown -- just roll a single finger over the top or bottom of it.But, I can see the Watch tattling to the iPhone:  Hey Siri, He's force-touching me! 
Actually, the curved top of the edges of the Apple Watch display are touch sensitive. Depending on the app you can pan or scroll by dragging on these areas without obscuring the screen. Nothing for zoom, though ... yet.
Not quite as trivial as you would make it sound ...Consider: You want to send a notification to Cindy:You know all of her device addresses!You don't know if she is using one or more of her devices!You don't know if she is within hearing or taptic range of any of her devices!You don't know the Off/On or battery/power status of any of her devices!You don't know the Internet connection status (wired, WiFi, Cell, no connection) of any of her devices!You don't know on which of...
Then, there's the  Grate [sp] Siri Face-off ... Consider, you're sitting around the family room, with several family members' iPhones and iPads plugged in -- charging or being used. You lift your wrist and to the Watch you say "Hey Siri" ... There's an instantaneous cacophony of replies from Siri on all your iDevices -- each vying for your attention ... "Pick Me" ... "No, Pick Me" ... "No, Pick Me" ...
