Apple’s new iPad 3 in Business: Wins and Losses
March 9, 2012 | 
Author 
On First Glance Not Much Different from iPad 2
You are not supposed to call it the iPad 3, rather the Resolutionary new iPad. The new iPad specs show that it has the same dimensions, weight, battery life of the previous iPads. The winning feature is the fabled retina screen, 2048 x 1526 pixels on 9.7 inch diagonal equal 265pixels/inch – very close to the point where the human eye can no longer distiguish pixels. And the new A5X processor is dual core for regular processing but quad-core for its graphic operations. RAM increases to 1GB by way of the A5X chip And the iS ight 5Mpixel camera is not quite equal to the new 41MPixel Nokia 808 PureView but it certainly moves the iPad up from its humble camera specs in iPad 1 and 2. Storage tops in at 64GB plus 2GB of iCloud space with fast 4GLTE network operation as better data mover. And the price, despite the reputed 25% increase in wages at Apple’s Foxconn manufacturing sources - the price is the same $499 for the 3G 16B unit.
The New iPad Catches Competition with Pants Down
As Tim Cook noted in his presentation there is no other tablet currently being delivered that can match the new iPad specs especially for screen resolution and speed and price for comparable specs. All the Androids currently top out at 1280 x 800 pixels and most are back at the old iPad 1024 x 800 or less. Only the upcoming Samsung Galaxy 11.6 tablet due out sometime in the Summer will have screen resolution a notch above the new iPad at 2560 x 1600 pixels and a 2GHz processor instead of the slower A5X. But we are talking futures in the case of Samsung.
And as for the Android OS powering the tablets, Jelly Bean,version 5 is expcted in June-July but no definitive word on features. In fact Google’s Andie Rubin, at the Mobile World Conference in Barcelona, was reduced to promising a major push for Android and its tablets “during the summer”. The speculation on the next version of Android, Jelly Bean, posits a Siri like Assistant, a File Manager, an ability to switch between Android and a loaded version of Windows – no idea if 7 or 8 with instant response, special malaware protection and the only real guarantee – a better version of Chrome the browser. Problem – vendors have yet to move to Honeycomb much less Ice Cream Sandwich versions of Android. Will Jelly Bean be compelling, stable and delivered on time enough to persuade tablet vendors to adopt Jelly Bean in prompt fashion??
On the Ultrabook front, Wintel is stuck at high prices between $900 and $1500 for ultra-slim laptops that cannot match the specs of the iPad 3 for battery life [9-10 hours] nor for screen resolution [2056x ]. Worse, the Intel Ivy Bridge processors are being delayed a speculated amount of time – IvY Bridge bring same speed at but double battery life for lower prices. And of course, the biggest mover, Windows 8, is now being posited as not available until the end of the year … and may not make Christmas sales. Windows 8 itself had its Consumer Preview reveal and is getting highly positive or deeply distressed reviews. Positive for Metro and touch interfaces, negative for its integration of Metro with the old Win 7 UI. So Win8 is still a dubious player until this time next year
And Nokia and Rim are preoccupied with getting their smartphone houses in order. Net result – expect at least two quarters of continuing dominance in tablet sales by Apple with iPad and the new lower priced iPad 2 and iPad 1 versions. And it could be a full year or more depending on how badly Apple competitors goofle. So count on Apple absolutely dominating the tablet market with its end consumer orientation. But it is in the Business market that Apple hopes to make its breakthrough and there are some ingredients for that in the iPad 3 … err, new iPad.
Apple and Business
I can remember working on a contract at Nortel Networks back in the late 1990′s and all the machines were Apple PCs and servers. But Nortel is gone and so is Apple in most business settings. And if many major shops like Fedex and Corrections Canada are just starting to move to Windows 7 this year – you can judge how daring business IT shops are. Ostensibly, the new iPad is designed to change that.
For example, hospitals and doctors will now have a screen equal to the task of showing all the Xray, ultrasounds, and other scans of their patients. And the camera will be equal to the task of recording with fidelity patient progress. Ditto for insurance agents documenting and servicing claims. likewise Apple has a vision of where iPad can be used in Business – but there are serious flies in the ointment as seen immediately below.
However, in both of the above cases the associated supporting medical or insurance IT infrastructures present problems. That IT business procesing requires multitasking and efficient data processing tools – not great iOS strengths. Multitasking is a privileged state for which Apple is loath to give developers unrestricted access because of malaware vector, reliability and battery life problems/costs. Data processing tasks and servers run into the Apple ecosystem pricing and access barriers. It is not a pretty picture trying to do Business with Apple.
Yes, Apple can point to HTML5, various XML and other document exchange systems, and the OnLive Windows in iPad story. But there are serious problem here too. HML5 moved along fast until about 2009-10. Since that time a number of serious and unresolved problems have continued to hamper HTML5′s progress. First, no major vendor is using HTML5′s Canvas and SVG and CSS3 in a major way – there a lot of start-ups but no compelling app. More seriously, key recommendaions like Forms, touchscreen UI, Web Databases, Web Offline operations and many others are in the state of limbo. Bottom line – HTML5 is not a robust Business solution space in contrast to consumer apps where games, videos, and blog reading are livable in the smartphone andtablet space.
But there are more serious Business IT problems. iBookAuthor has shown what the toll that going without Flash takes in multimedia settings. Even moderate sized iBookAuthor texts eat up 2-4GB of the precious storage available on iPad. True one can send and receive the book on demand from the iCloud or DropBox , but this defeats the handy reference idea. As well, Java has been banned on iOS – and so much of the local lient supporting infrastructure for XML and other document exchange mechnisms used by Business even on the Mac which is heavily Java coded have to be changed for the iPad’s Objective C.
But Objective C presents another problem again for developers. Although Objective C is C programming language inspired, it is more than C and definitely not C++. And the iOS version of Objective C is different from the Mac version although the programming libraries are starting to converge. But the bottom line is that Apple imposes on software and business developers another language with little cross platform capabilities. In addition, just as Java and Flash have been banned there is scarcity of other client programming tools such as Ruby or Python or Groovy except in iOS native dialects .
Finally there has been talk of the OnLive desktop solution of bringing Business to the iPad. The OnLive desktop service that brings Windows 7 and Microsoft Office screens to customers on iPads with very fast response time. But OnLive has run into 3 hurdles. First, the Windows 7 sessions are delivered from a server not from the users local PC. Second, the response time is dependent to an extent on the screen size for the iPad and that has increased withthe new iPad by a factor of 4. Third, Microsoft and onLive are having a disagreement on what can be done with customers using Windows 7 and Office – see here for details.
Summary
Pundits have failed to give proper credit to the new iPad. it is loaded with screen, battery, camera, and CPU features. It gives Apple another 3 to 6 quarters of likely dominance of the consumer side of the tablet market. But the tide may be turning decisively in Apple’s favor if consumer sales explode without a Android por Windows response to iPad 3 specs. This may help carry the way in the Business market as end users demand iPad support at work.
However, as we have seen, a)Business IT is very conservative and b)even the new iPad, its ecosystem and closed programming present real problems for Busines IT as well as business software vendors. These are not simple issues – so expect a stormy rollout of iPads in Business.

jsFiddle: JavaScript Test and Demo Environ
In our review of the top ten books on jQuery, I recommended W3schools.com JavaScript and its jQuery pages as the place to go for testing out the code you find in the various book pages. However, there is another and perhaps better option for testing and demoing your JavaScript framework code – jsFiddle.
jsFiddle provides the same edit and test environ that W3schools does – all the JavaScript and CSS links are predefined but then goes 2 or 4 steps further. First, jsFiddle supports about a dozen JavaScipt frameworks including the most popular like Dojo, EXTjs, Mootools, jQuery, Processing and YUI. All the frameworks have several versions available – for example, Mootools versions 1.1.2. thru 1.4.4 are available and so on for the other frameworks. This is no small matter for developers who have to test fit in code into different framework versions on various servers.
I also like the separate editable panels for HTML, CSS, and JavaScript. This is the layout users find for many of the web or ebook tutorials explaining the use of the JavaScript widgets and frameworks. So users can easily cut and paste to the apprporiate panel. Also as you refine a widget, it is convenient to go to HTML and CSS panels rather than on a huge panel with all the code. To get at the final code you is a bit strange. Put the URL http://jsfiddle.net/yourregisteredjsfidlename/draft in a new web browser window. The hit CTRL U to get the source and save it.
jSFiddle panels use color coding helping to identify operators and elements. In addition, watch the color coding carefully. Change a HTML tag name and the closing tag turns to red in color until you change it. Like wise for braces, brackets, and parentheses in the JavaScript, CSS, and HTML panels. For example, if you add an opening bracket it is red and will remain so until a balancing bracket is entered. Put the cursor next to brace, bracket, or parentheses and it turns green if their is a balancing one – otherwise it will be red. Currently this color coding help does not extend to single or double quotes in any of the panels. But it does to HTML tags – but only partially,as jsFiddle is alpha code.
Other jsFiddle Features
Highlighted in yellow on the screenshot of jsFiddle above are 5 other nifty features for test and demo environ:
1)with the Add Resources accordion button developers can add additional framework script and link resources – very handy for complex and/or multi-framework apps;
2)the Info button allows changing the title, description, body tag and HTML DTD used for the test page;
3 in the toolbar on the top of the jsFiddle screen – the TidyUp button uses the Tidy program to format the contents in the JavaScript panels/windows. It would be nice to have it apply to HTML[which it was originally written fo] and the CSS too;
4)in the toolbar again, the JSLint button runs the JavaScript checking routine giving precise error messages where the JavaScript has gone bad. This is better/more precise than the Google Chrome IDE and Firefox’s otherwise excellent Firebug console;
5) the Share button is why I call jsFiddle a demo environ. jsFiddle creates a)shortcode URL to get at the browser session; b)iframe code to embed the session on your blog/website; c)Facebook and Twitter embed codes. In sum this is a great environ to also demo what you plan to do.
Here is what jsFiddle looks like in live action:
This is simple jQuery demo code in which the Tidy, JSLint, and panels helped to speed along development.When you try it, jsFiddle is a winner.
Summary
jsFiddle is a well composed JavaScript test and demo environ that deserves its testing mettle. Come here for testing out those code snippets from web tutorial sites or kindle code recipe books. This saves you the trouble of creating the equivalent code in Notepad or your favorite Web IDE. And then jsFiddle is geared to getting the mesage out to your development team. Its a very convenient way of demonstrating to client and other team members status of development on key components of a system. Even though this is self-proclaimed alpha software, in fact it is a keeper for any JavaScript or Web developer.
The Better jQuery Bookshelf
jQuery deserves its reputation for being a breakthrough JavaScript framework for 4 reasons. First, it is open source in every incarnation which has accelerated its use and adoption even by major software vendors like Adobe, WordPress and even Microsoft. Second, it is the APL of JavaScript. jQuery’s selector function create a shorthand for finding all the objecrts on a Web page in simple condensed notation – $(” div .plusStyle”) finds all div tags within a web page that have used the class plusStyle for CSS styling. This notation eliminates tedious JavaScript search code. Then users can add any of dozens of methods to operate on all of these objects with simple one line calls – again eliminating many lines of tedious looping code.
Third, jQuery has rigorously followed the W3C DOM and CSS code standards in its selector and operational methods. This has been one of the first complete demonstrations of the the utility of the W3C DOM and CSS standards in JavaScript. It also has had the added benefit of providing an emergency hack for getting around Microsoft’s non-compliance with W3C standards. It has relieved developers of some of the misery of dealing with the still existing and deviant IE5 through IE8 browsers [even IE9 leaves some large gaps in standards compliance].
Fourth, jQuery has provided some novel graphics methods which has spawned its own UI group and a fast growing and innovative jQuery UI framework. This UI frameworkhas been the source of scores of free UI and mobile plugins and widgets enriching Web client computing greatly. For example, Adobe is using jQuery as the driving engine for its Edge animation program that uses no Flash and all HTML+CSS code[Edge still does not need routines exclusive to HTML5 though Adobe implies that will be coming].
Thus if you do any Web development you owe it to yourself to become jQuery capable. This is a list of books that can get you up to speed quickly. Here are our key Tomes for jQuery.
JavaScript: The Definitive Guide by David Flanagan
Why a book on JavaScript? Because this is the first book that covers all the features in JavaScript comprehensively including some of the specialized function and array features of JavaScript used extensively by jQuery. It is truly the Definitive Guide. As well there is a section in the book devoted to jQuery. And if you need to come up to speed in JavaScript using this book along with the W3schools’ JavaScript tutorials is one of the fastest ways to come up to speed quickly. Then keep the Definitive Guide for its encyclopedic coverage of JavaScript.
Head First jQuery
Head First series of books use all sorts of visual clues, quizzes and thought experiments to make material fun and memorable. I find that it works very well with jQuery because the topic requires focus and concentration. Again, this a is a great book to use in conjunction with W3schols jQuery set of tutorials. The books exercises can be easily done there and get users used to testing out their jQuery ideas right away in the W3schools test interface.
This is the book that I constantly use as my cheat sheet for jQuery development. Its like the iPod of books for jQuery development with two quick explanatory chapters and then a comprehensive set of referrence guide sections. the only thing that comes close is the JQAPI Adobe AIR version of jQuery documentation. But until a good dockable tablet becomes available, I carry Flanagan’s jQuery Pocket Reference everywhere.
The Plus PC World: Client Computing Directions
The Technology pundits have it all wrong – calling for a Post PC World. Over on Reddit, we are having a small debate on the Post PC World versus the Plus PC World. The Post PC World see the decline of the PC as they are replaced by smartphones, tablets, games and other mobile devices . The Post PC World also sees the rise of new client OS with primacy placed on touchscreen operations, ease of use, low power usage , and therefore strict control of multi-tasking. Apple iOS is the best examplar.
The Plus PCWorld takes the view of rapid convergence of the smartphone, tablet, gaming, and PC Worlds. Moores Law is again at work continuing to deliver a doubling in computing power [and dragging along storage, display area, and communication bandwidth with it]every 18 months or less for the same price. For example, quad-core chips are being delivered in smartphones and tablet. the result is that every device can be a PC. Okay, not equivalent to todays fastest and best PC – but able to run the best of PCs from 4 -5 years ago. And most importantly run the bulk of programs and apps with good response time, ease of use, and that users want: a browser, email, word processing, simple games, videos and maybe 2-3 special apps/programs. But there are two other phenomena pushing towards a Plus PC World – Convertibles and Cross Platform Compatibility.
Convertibles
Smartphones [see Motorola Atrix ] and tablets [see Asus Transformer Prime] are becoming convertibles. Game consoles like like Sony Ericsson smartphone are becoming expanded use convertibles. Users can hook more smartphones and tablets into docking stations with more traditional PC conveniences such as a full keyboard, a trackpad, more and better battery-life, more ports and disk storage. And these devices now have the equivalent of PC computing power from just a few years ago.
Alternatively, WiFi Direct or Bluetooth bring about device-to-device or to network port/docking station connectivity at ever higher speeds of up to 25MB/sec. This makes virtual connections among devices an alternative to wired connections; but also this place a premium on being able to communicate easily between devices.Thus being able to run the same or familiar OS and apps on those devices will be a winning option for the expanded Client Computing. As Client Computing devices converge on features, speed of operations, and quickly achieved portability – then compatibility and a common OS infrastructure becomes a primary concern for consumers. Next consider cross platform compatibility for businesses and developers.
Cross Platform Compatibility
Cross Platform Compatibility has rarely won against proprietary systems with “better” feature sets. OS2 vs Windows is the best example of that to business’ great duress when Windows went onto major reliability, bugs, security and pricing problems that can still plague the OS 20 years later. So the emergence of mobile OS like Apple iOS and Google Android raise the question of cross platform compatibility.
Now Steve Jobs conveniently “solved” the compatibility problem while banning cross platform tools like Flash, Java, and program generator output from his iOS devices. Steve’s solution was HTML5. But even two years ago HTML5 had some serious discrepancies among vendors as this interview with W3C HTML5 Editor Ian Hickson reveals. Since then issues with Touchscreen UI, Web databases, CSS3 styling, and Offline Work among others have grown contentious between major software vendors of both OS and browser makers. Add to this the problems of general Web HTML performance and security problems – and HTML becomes no magic cross platform solution.
In fact developers face an increasing Babylon of Programming Languages and Database Systems[ NoSQL anyone?]. Look at just the largely incompatible Operating Systems for Client Computing:
1 – PC OS – Linux, Mac, Windows
2 – Smartphone and tablet OS – Android, BBOS, iOS, Windows Phone and Windows 8
3 – Gaming consoles - Nintendo 3DS, Playstation OtherOS and Vita, Xbox 360
4 – Cloud Operating Systems – Amazon EC2, Apple iCloud, Google Chrome OS, IBM eyeOS, Microsoft Azure,
Now for the past 30 years[if not 60 years] isolated islands of information have been at the top of IT Problems for organizations large and small. Isolated sets of incompatible devices have plagued consumer computing. PCs brought a measure of unity for Client Computing. But the Post PC versus Plus PC OS directions will answer whether the problem of isolated island expands or contracts. How do the major client computing OS vendors stack up.
Client Computing Directions
The client computing vendors have distinct positions on their OS as the table below suggests:
| Category | Apple | Microsoft | |
| Smartphone | Most Apps – 600,000 mind share leader 2nd in market share |
2nd in Apps – 400,000 1st in market share |
Well behind in apps and market share |
| Tablets | Most Apps – 120,000 1st in market share |
2nd in Apps – 40,000 2nd in marketshare |
Well behind in apps and market share |
| Mobile OS position | Proprietary Few languages for development strict control of multitasking No cross platform tools Closed ecosystem |
Open Source Many languagesOpen 3rd party multitasking Some cross platform tools Semi-open ecosystem |
Proprietary Many languages but some proprietary Open 3rd party multitasking Some cross platform tools Semi-open ecosystem |
| Game Consoles | Mobile iDevices only | Mobile iDevices only | Proprietary Xbox and Kinect UI Market share lead |
| PC | Proprietary 2nd Most Apps Small Server presence |
No real OS presence Chrome OS?? |
Proprietary 1st in Apps 1st in market share 2nd Server OS |
| PC OS | Proprietary some cross platform tools 2nd in languages for development |
No real OS presence Chrome OS?? |
Proprietary some cross platform tools Most languages for development |
| Futures | Dividing line appears to be iOS Mac equals no touchscreen, no iOS emulation, no VM support except on Mac HW In iOS touchscreen exclusive no cross platform support restricted multitasking iCloud exclusive to iOS iOS in Apple TV |
Chrome OS emerges?? Android makes jump to PC?? Google buys Canonical?? Android becomes game and TV console controller |
Windows 8 supports PC and tablets Windows 8 converges on Phone 7 Supports Microsoft Azure for Cloud Supports some 3rd party Clouds but not as closely Xbox 360 and Windows 9 converge?? |
Clearly no one OS vendors has the lead across the board in the current and future Client Computing OS platforms. But Apple clearly has the lead.
In client computing OS, Apple has become the new Microsoft. Its OS systems are moving to ever more rigorously closed and proprietary base. This is all good as long as Apple can lead the innovation mind share parade in hardware fact as well as OS features. Also, the Mac hardware and OS/X have been treated as poor cousins – no touchscreen operations, 2-3 times the price of identically equivalent PC hardware, slow transition to iOS feature set. The upcoming Mountain Lion OS/X will catch up to many but not all iOS features.
It appears Apple is convinced of 3 things. First, the Post-PC era will bypass PCs except for niche operations. Typically these will be specialty apps like multi-screen desktop configurations, high-end graphics processing, large development machines, and/or desktops devoted to heavy analytics. Second, Microsoft will do a Vista on Windows 8 – have some show stopping bugs or feature misses that they can smirk in TV ads again – “We told you so”. Third, that the need for cross platform capabilities is over-rated and the speed of machine operations, ever faster communication bandwidths, and HTML, XML, and other data exchange formats will obviate the need for any real cross platform support.
Google, despite doing well in smartphones and inspiring a flood of just great tablet hardware designs, is still firmly entrenched in protecting its Search Business and their own access to Client Computing. As long as that is true there is no need for a Google PC desktop presence and therefore there remains a big gap in Google’s Client Computing OS presence. Besides, Facebook is the real enemy with all its 800 million users and the amount of face time they spend in Facebook and the search engine Facebook is working on.
Ye Editor has advanced the idea that any vendor that has an Open Source OS should be exempted from any limits on app market share. Given that Google’s Android and Chrome OS are both Open Source this would appear to offer an opportunity for Google to get into app software in a bigger way. But the app software market, except through the Cloud, does not appear to meet the Google business model. Google appears committed to Chrome and the Cloud and thus a Post PC World.
Microsoft has looked like the ugly duckling in Client Computing OS for the past 10 years. They simply missed the mobile OS marketplace despite owning its entry points and trying all sorts of tablets, Mobile CE, and phone operating systems. Ballmer lacked Jobs vision that PCs with ever greater computing power had a)become cumbersome to use with many programs having large learning curves and/or remember how to us and b)had for most users raced beyond the consumer computing sweet spot , and c)discounted too much the importance of portable/mobile = light and long-battery life devices capable of knowing their physical state [GPS, ambient light, orientation sensors, altimeters etc]. Then Steve Jobs navigated to the consumer computing sweet spot by trial and error delivering the full range of audio/visual media on iPods; then user phone and Internet connectivity with the iPhone and finally renewed emphasis on ease of use with iPad offering exclusive touchscreen operations in the Apple OS universe.
But Steve Jobs was not infallible – he was originally dead set against 3rd parties being able to create iPhone apps. And the latest Apple magic, Siri, was developed outside Cupertino. But credit Steve and the Apple engineers for seeing the opportunity. Siri has brought voice out of the computing UI desert despite many attempts from IBM, Microsoft and others to deliver it into the computing interface world [But Siri will not work well in business and organizational settings where cross chatter interference will shoosh it up].
But also give Redmond credit, they have recognized their extremely vulnerable position and are betting the farm on Windows 8. Whats in Windows 8 is a series of big bets from the new Resilient File System through Live Tiles as Dashboards to Picture Passwords. Microsoft is “all in” on Windows 8. But the crucial bets are three. First, by bringing a Sensor API, touchscreen operations and the Metro interface up to the Desktop, Redmond is betting that the legion of desktop software vendors will be able to inject new vigor and ease of use into their desktop apps while porting others to the tablet and mobile devices. This is the Plus PC vision – the desktop does not have to wither and die; but given light and portable options can flourish with the new Windows 8 enablement of knowing the state of the machine. This means that Windows 8 will be able to take advanatge of the new convertibles hardware better than Android or iOS.
Second, by bringing Live Tiles, Hubs and true multitasking to tablets and other mobile devices, Windows 8 developers will be able to take advantatge of the huge computing power coming to smartphones and tablets with quad core procesors and new SSD storage capabilities. Windows 8 developers will not just have all of the iOS-like touchscreen and sensor APIs but have more programming leeway to deliver “software magic” on Windows 8 than on iOS.
Third, despite maltreating Windows Web developers over the past decade, Redmond understands the developers, developers, developers advantage. Thus by rescuing their desktop apps, providing multiple language streams for development, and relaxing some of the burdensome Apple ecosystem constraints, Microsoft will initially hope to get enough developers on board to deliver some compelling mobile and desktop apps. Personally, Ye Editor drools at the opportunity to run a touchscreen version of Adobe Photoshop or Corel Paint. Ditto for Microsoft Project or Netbeans Java IDE. Or Techsmith Snagit.
Summary
Steve Jobs and Apple broke the Microsoft Client Computing monopoly – Redmond now has about a 50% share of client computing OS. With smartphones, tablets and extremely portable and long life computing devices, the PC dominance of client computing ended. But with enormous computing power and storage and high res screen size coming to all devices including smartphones, tablets, PC laptops and ultra compacts, the ball game changed again. All of the devices from smartphones through tablets to notepad/ultra compacts have nearly the same computing power at their disposal. And with docking stations or WiFi Direct, mobile devices can become transformable or convertibles. This changes a Post PC World into a Plus PC World if the right software is offered. And Microsoft is working triple overtime trying to make sure that the “right software” is offered. And come February 29th, users worldwide will get to see how right the software is with the Microsoft Windows 8 beta or Consumer Preview launched that day.
The Blog Becomes The OpenSourcery Home Page
Reality is being reflected:
The OpenSourcery.com Blog KeepOpen is now the Site’s Home Page
The old website start page is here and can also be accessed from Old Website menu item. All theopensourcery.com web pages are untouched and intact. You should be able to access them with their existing URLs with no problems. However, making this move to the WordPress blog format means:
1)Ye Editor will be practicing what he preaches;
2)Open up opportunities for 3rd party contributors. Send an emeil to Ye Editor if you are interested;
3)Opens up the powerful search engine to find earlier postings and topics;
4)The categories option in the sidebar also should get more use;
5)Also opens up some layout and styling opportunities in the next few months.
Hope readers like the new digs.
