Windows on the iPad

20 05 2014

Microsoft introduced an operating environment named Windows on

November 20, 1985 as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUI).

Microsoft Windows came to dominate the world’s personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984. As of October 2013, the most recent versions of Windows for personal computers, mobile devices, server computers and embedded devices are respectively Windows 8.1, Windows Phone 8, Windows Server 2012 R2 and Windows Embedded 8.

Tablets …

Touch screen technology has brought about a revolution in the new-age and broadcast media industries and is now widely adopted by Television, Computer, Mobile Phones and Camera manufacturers. Tablet computers are among the most visible manifestations of this technology and are seen as a possible replacement for regular desktops and laptops in the foreseeable future.

The majority of tablets are available in 2 sizes, 7 and 10 inch.

Note
Some tablet manufacturers make also 8 and 9 inch tablets. Few models can be found with large than 10 inch display sizes, in majority these are Windows based tablet computers.
There are several aspects about tablet displays which a discerning customer should consider before considering one of the manufacturers for the final purchase.

There were already early beginnings in finding out the right screen size.

20140218-073438.jpg

There are many requirements for suitable tablets which basically remain the same independent of the screen size. So let’s have a look on some technical specifications.

1 Display resolution …

Screen resolutions vary according to the manufacturer and the price range in which the tablet is sold. From the QXGA resolution on the new iPad to the WVGA resolution that is found in the most basic models, there is a wide choice available for the consumer depending on his or her personal needs.

Typically, the screen resolution can be categorized as follows:

QXGA 2048 x 1536
WXGA 1366 x 768 or 1280 x 800
XGA 1024 x 768
WSVGA 1024 x 600
WVGA 800 x 600

Tablets of smaller sizes such as the 7 inch can do well with a lower resolution screen. Higher screen resolution becomes relevant as the tablet size increases.

2 Screen coating, Brightness and Protection …

Since tablets are highly portable devices, they are widely used indoors and outdoors. While screen brightness is not really an issue when used indoors, these tablets can become highly reflective in outdoor daylight conditions and therefore needs the screen brightness to offset the ambient brightness. Most manufacturers have overcome the problem by using a coating that prevents glare while also protecting the glass from scratches and dirt. If your tablet display is protected using a toughened glass such as Gorilla Glass, the chances of screen cracking due to the tablet accidentally falling on the ground is minimized.

3 Screen Viewing Angles …

While this may not be a major concern if you are using the tablet as a hand held device, screen dimming and colour change can be an irritant if you are placing the tablet on a stand or keeping it on a table for people around you to see. This problem is normally found in LCD displays made using TN technology. Colours like red, blue or green become darker and the screen becomes dimmer as you move away from the centre of the screen. Make sure that you get to test this out on a demo piece at the retailer before you choose your tablet. Most modern tablets do not use the TN technology in their LCD display.

4 Screen Technology …

There are 2 prominent TFT (Thin Film Transistor) LCD Screen technologies available today.

In Plane Switching technology or IPS was developed in Japan in response to the viewing angle problems caused by LCDs based on twisted nematic display technology. IPS LCD screens have almost no viewing angle colour changes.

Plain Line Switching or PLS is a relatively new LCD technology and was developed by Samsung in Korea and has lower manufacturing costs as compared to other LCD technologies. With improved image quality, viewing angles and screen brightness, PLS is expected to address several of the issues faced by tablet manufacturers.

Samsung’s way …

On 12.2-inch models, you can also split the screen into four, to run four visible apps at the same time. You might display your email app, next to your browser, next to a video, while editing an iWork document.

Samsung already refreshed the traditional Android interface. Instead of grids of icons for a home screen, the tablets show a magazine-like layout that separates apps and content into different tiles and pages.

Samsung’s emphasis on professional users for tablets is a direct effort to compete with Microsoft’s Surface tablets, which are marketed as a more viable replacement for a laptop suitable for work. But it is also an effort to take on Apple, whose iPads are widely used by workers in various fields, like construction, medicine and food service.

20140217-084416.jpg

Apple, it’s your turn now to say Good Bye to the One-Window technique.

Increased screen size …

There are rumors about an iPad coming in 2014 with an increased screen size. The actual screen size is 9.7″ and sources speculate about a screen size up to 13″.

If this will come true what would the intention of Apple be?
Would the customers benefit from a larger screen size?

To answer these questions we should look at the motivation of users when buying a tablet. Well-known daily tasks are mailing, shopping, and banking and stats of Apple’s App Store say that nearly all of the top ten downloaded apps are games.

20140217-085455.jpg

For this kind of usage an increased screen size is dispensable. This is also validated by increasing sales of the iPad Mini.

So the only reason for launching a bigger screen size could be to use a tablet for professional tasks like editing documents, e.g. spreadsheets, presentations, and letters with Apple’s iWork suite while accessing sources shown in other apps, e.g. websites in Safari.

  • 1 With the actual operating system iOS 7 for mobiles an increased screen size will not solve the following problems:

    - Files still remain in a fragmented file system followed by redundancy.

    ( see my post http://iNotes4You.com/2012/10/11/the-ios-filesystem )

    - The One-Window-Technique is the main disadvantage when working with more than one application. It’s a daily task to retrieve information from one window and use it in a window of another application.

  • 2 Embryonic clipboard
    Working a bit more effectively affords an advanced clipboard with multiple entries.
  • 3 Mobility is slightly decreased.
    Weight and energy consumption could hamper the usage of a tablet with a larger screen size. The size of the device depends on the bezel which is actually about 0.79″ (2cm) for the actual iPad Air. A minimum bezel width of half of this value would be acceptable and the total size of the device would’t really decrease the mobility.
  • 4 Stats for the iPad Mini show us that many customers seem to go the reverse way regarding screen size. This decreases the number of potential customers for an iPad Pro. An overview of all actually available tablets show us that all manufacturers see the perfect screen size within a range of 7 to 10 inch.
  • 5 With the iPad Air Apple developed a tablet with an incredibly reduced weight and a battery life which lets you use the device a whole day. A bigger screen and improved multitasking will possibly roll these advantages back.

Windows and the operating system …

To enable a tablet for a more professional use it should offer

  • application windows
  • real multitasking
  • an increased memory
    to handle different tasks and to not let more complex applications fall into the suspended state

I’m no iOS developer so I cannot estimate whether iOS 7 already was designed for important changes in the near future.

So my presumption is that Apple will not just increase the screen size. The new iPad Pro (if there will be one) will show us application windows with an improved iOS 8 or an operating system named Mavericks for mobiles.

It needs some innovative power to organize windows on a touchscreen and find intuitive gestures to use them.

A workspace for innovation, right? And with that a case for Apple.

Suggestions …

My suggestions are based on a Two-Windows technique following the KISS principle.

A UI for the following tasks has to be developed …

  • Open two or more windows
  • Switch between windows
  • Maximize one of the windows
  • Return to ‘Two/Multiple-Windows’ display

(Tap on an image to zoom.)

Increased size doesn’t matter …

Actually tablets are used mainly because of their mobility and a more relaxed usage when reading information. Here is what Ben Bajarin wrote on TabTimes:

People see this device and realize that it is in fact a computer. This fundamental point is where the paradigm shift to tablet computing is about to happen.

The amazing thing about a tablet, that sets it apart from every device I have and use it that has more computing capabilities than my phone and is more portable/mobile than my notebook.

I can sit reclined on my couch or bed and learn, work, or play. I can take it to the office and work. I can use it as portable TV or DVD player. I can use it to make home movies. I can use it to make music. I can take it to the lake and capture video of my family water skiing and edit and create the video right there on the lake.

I can keep going with these scenarios but you get the picture.

This is why, I believe it has the most potential of any form factor out there with regard to the future of computing.

We can read statements like this quite often and I never read any suggestions for a bigger screen size. So the question is:

Is there a market for tablets with screen sizes near to 13″?

Sam Beckets concept …

Sam Becket published a concept video in December 2013 showing multitasking on an iPad.

(1:06 min)

Summary …

A bigger screen size for an upcoming iPad makes no sense without improvements of the operating system. Even then mobility decreases and there are only a few applications where an iPad with a screen size near to 13″ could make sense.

It’s easy to forget that people once marveled at the interactive tablets carried around by characters in Gene Roddenberry’s Star Trek, or the touch screens in Spielberg’s Minority Report – dream futures that have become reality.
In 1983 Apple co-founder Steve Jobs stated that his ultimate ambition was

“to put an incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes…”.

That vision would take him 27 years to realize.

With the release of the iPad mobile devices reached a new quality because of it’s screen size and the possibility to operate them just with the fingers and without any peripherals. They initiated a shift in paradigm of teaching and learning as well and from that time ‘people could hold the internet in their hands‘.

Historically the term first originated when Apple‘s founder Steve Jobs discussed the future of personal computing during an interview alongside Bill Gates at the fifth All Things Digital conference in 2007. At that time he described

“a category of devices that aren’t as general purpose, that are really more focused on specific functions, whether they’re phones or iPods or Zunes or what have you. And I think that category of devices is going to continue to be very innovative and we’re going to see lots of them,”

Jobs said.

20131223-100235.jpg

It wasn’t the first tablet computer by any means, and the iPad faced significant criticism when it was first announced – most pointedly the accusation that it was trying to fulfill a demand that didn’t exist. But the iPad surprised everyone, instantly spawning a market for a new form of computer that made the internet touchable and found its way into the hands of 170-million customers in its first three-and-a-half years.

There are some quite astonishing engineering feats behind the iPad. The iPad Air (launched in 2013), for example, weighs twenty times less than an Apple Mac from ten years ago, but packs four times the memory and four times the processing power. The glass that covers the screen is manufactured via a process which makes it harder than sapphire, and is coated with an invisible oil-repellant to reduce fingerprint staining.

20140329-121852.jpg

But most incredible of all is the fact that Jobs succeeded in coming up with a portable – and connected – computer that even orangutans in the Smithsonian National Zoo have worked out how to use, forever altering the future of digital media in the process.

A tablet …

When Steve Jobs ended years of speculation in 2010 by announcing the iPad tablet device, he helped launch a new era in computer hardware. Though tablet PCs have been around for years, the iPad was the first device to use the form factor successfully in the consumer market.

So what exactly is a tablet?

At its most basic level, a tablet PC is a mobile computing device that’s larger than a smartphone or personal digital assistant. In general, if the computing device uses an on-screen interface it’s a tablet.
To confuse matters, some manufacturers produce hybrid devices that are part tablet, part laptop computer. The device might come with an attached keyboard — the screen swivels or folds down to cover the keyboard and voila, you have a tablet!

In 2010, Lenovo introduced a prototype device called the IdeaPad U1 at the Consumer Electronics Show in Las Vegas, Nev. At first glance, it looked like a normal laptop computer. But if you detached the screen from the base, the laptop converted to a tablet computer with its own, independent operating system. Lenovo rebranded the device, naming it the Lenovo LePad and launching it in China in 2011.

The touch screen …

Thousands of scientists, their researches and inventions, the ongoing miniaturization, and improvements in sensor technology made a smartphone and a tablet ready for use.

All tablets have a touch screen interface and an operating system capable of running small programs and interpreting gestures. Further sensors are used to automatically change the orientation from portrait to landscape mode.

Summarized, it was the touch screen first introduced with the iPhone in 2007 and it’s multi-touch capable operating system iOS which made the iPad to a device capable to replace computers for an increasing number of people.

The development of the Touch Screen Technology started in the 1960s although there are many results of basic scientific researches in physics starting hundreds of years earlier.

1960s

Historians consider the first touch screen to be a capacitive touch screen invented by E.A. Johnson at the Royal Radar Establishment, Malvern, UK, around 1965 – 1967. The inventor published a full description of touch screen technology for air traffic control in an article published in 1968.

1970s

In 1971, a “touch sensor” was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor called the “Elograph” was patented by The University of Kentucky Research Foundation. The “Elograph” was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology. The Elograph was selected by Industrial Research as one of the 100 Most Significant New Technical Products of the Year 1973.
In 1974, the first true touch screen incorporating a transparent surface came on the scene developed by Sam Hurst and Elographics. In 1977, Elographics developed and patented a resistive touch screen technology, the most popular touch screen technology in use today.

In 1977, Siemens Corporation financed an effort by Elographics to produce the first curved glass touch sensor interface, which became the first device to have the name “touch screen” attached to it. On February 24, 1994, the company officially changed its name from Elographics to Elo TouchSystems.

1980s

In 1983, the computer manufacturing company, Hewlett-Packard introduced the HP-150, a home computer with touch screen technology. The HP-150 had a built in grid of infrared beams across the front of the monitor which detected finger movements. However, the infrared sensors would collect dust and require frequent cleanings.

1990s

The nineties introduced smart phones and handhelds with touch screen technology. In 1993, Apple released the Newton PDA, equipped with handwriting recognition; and IBM released the first smart phone called Simon, which featured a calendar, note pad, and fax function, and a touch screen interface that allowed users to dial phone numbers. In 1996, Palm entered the PDA market and advanced touch screen technology with its Pilot series.

2000s

In 2002, Microsoft introduced the Windows XP Tablet edition and started its entry into touch technology.

Note
Until today I use a Siemens T4010 Convertible running on the XP Tablet edition with a stylus and an incredible weight of 2.5 kg.
It just works, but it works more like a heater if you place it on your lap and because it’s running XP you have to take care of it’s health with an antibiotic therapy each week.

However, you could say that the increase in the popularity of touch screen smart phones defined the 2000s. In 2001 Mitsubishi launched the DiamondTouch (a human interface device that has the capability of allowing multiple people to interact simultaneously while identifying which person is touching where).

Various companies expanded upon these inventions in the beginning of the twenty-first century. The company Fingerworks developed various multi-touch technologies between 1999 and 2005, including Touchstream keyboards and the iGesture Pad. Several studies of this technology were published in the early 2000s by Alan Hedge, professor of human factors and ergonomics at Cornell University. Apple acquired Fingerworks and its multi-touch technology in 2005. In 2007, Apple introduced the iPhone still seen as the king of smartphones with nothing but touch screen technology follwed by the iPad in 2010.

There are basically three components used in touch screen technology …

  • 1 The touch sensor is a panel with a touch responsive surface. Systems are built based on different types of sensors: resistive (most common), surface acoustic wave, and capacitive (most smart phones). However, in general sensors have an electrical current running through them and touching the screen causes a voltage change. The voltage change signals the location of the finger.
  • 2 The controller, is the hardware that converts the voltage changes on the sensor into signals the device can receive.
  • 3 Software tells the device what’s happening on the sensor and the information coming from the controller. Who is touching what and where; and allows the operating system and apps to react accordingly.
    To improve the features multi-touch was introduced to recognize the presence of two or more points of contact with the surface. This plural-point awareness is used to implement advanced functionality such as pinch to zoom.

Summary …

The iPad is in the line of disruptive innovations. It seems to become a tool supporting all areas of life, household, education, science, health, communication, etc. It’s for primates but still not for apes who grant preferences to other activities.

Two running systems

16 02 2014

There are some similarities between an iOS device and a human being. Here is a simplified explanation of a computer-like device by using some well-known facts about human beings. Which of them is more complicated cannot be assessed. But it’s obvious that humans learn during their whole life whereas the basic skills of a device are fixed when the production process ends. Adding further skills means installing apps but even features of apps are already clearly defined by the developers.

There is a one way connection between the owner and his device because the owner has access to uncountable information saved on internet servers, can improve his skills and personality, and can be creative when using his brain and e.g. a mind mapping tool or an iWork app.

The comparison …

Basics of the two systems are summarized in this mind map.

20131120-144435.jpg

Feel free to download this map from my Box account.

The alternative file formats have been created with iThoughts HD for iPad (.ITMZ file format). Compatibility to other tools is limited.

The differences …

Comparing the two systems might be useful for those who are not deeply involved in computer technology. So first of all let’s see where the differences are to avoid misconceptions (Source, modified). Keep in mind that these differences are not valid for supercomputers with hundreds of processors or implemented artificial intelligence. We are just talking about an iOS device with a single processor.

  • 01 Brains are analogue; computers are digital
  • 02 Brains uses content-addressable memory
  • 03 Brains are massively parallel machines; computers are modular and serial
  • 04 Processing speed is not fixed in the brain; there is no system clock
  • 05 Short-term memory is not like RAM
  • 06 Brains cannot be divided in hardware/software
  • 07 Synapses are far more complex than electrical logic gates
  • 08 Processing and memory are performed by the same components in the brain
  • 09 The brain is a self-organizing system
  • 10 Processors only can handle commands predefined by the operating system
  • 11 Brains can learn
    As far as I know there are two areas where even iOS devices improve their capabilities over time. When writing words iOS saves frequently written words in an individual dictionary. Power management adapts to usage over time.
  • Bonus Difference
    The brain is much, much bigger than any [current] computer.
    Accurate biological models of the brain would have to include some 225,000,000,000,000,000 (225 million billion) interactions between cell types, neurotransmitters, neuromodulators, axonal branches and dendritic spines, and that doesn’t include the influences of dendritic geometry, or the approximately 1 trillion glial cells which may or may not be important for neural information processing. Because the brain is nonlinear, and because it is so much larger than all current computers, it seems likely that it functions in a completely different fashion. The brain-computer metaphor obscures this important, though perhaps obvious, difference in raw computational power.

Source

Processor and apps …

The mind map shows that the kernel of an iOS device has to be divided into processor, operating system, and memory.

The Memory

During installation of a new app, the installer code creates a home directory for the app, places the app in that directory ( /AppName .app) and creates several other key directories. These directories constitute the app’s primary view of the file system located in the memory of your device and represents the universe for that app. It contains everything the app can access directly.

20131120-150432.jpg

If you create a document (e.g. with Apple’s Keynote) or receive one via E-Mail you possibly want to further work with it in another app. In Apple’s filesystem this is not possible by default.Interactions of an iOS app are limited mostly to the folders associated with it. This limitation is labeled Sandbox-Mode and was designed to increase the security of the filesystem. Unfortunately it also decreases the usability in many cases.

Note …
One exception to this rule occurs when an app uses public system interfaces to access things such as the user’s contacts or music. In those cases, the system frameworks handle any file-related operations needed to read from or modify the appropriate data stores.

The Operating System

If you tap on a control within an app (or you generally touch the screen), the app (the touchscreen) sends a specific command to the processor which communicates with the operating system to retrieve the necessary further tasks. The processor only can handle commands which have been defined by Apple (implemented in the operating system), the developer of the operating system. Programmers (companies where you het your app from) use these commands to let you interact with their app.

The Processor

A central processing unit (CPU), also referred to as a central processor unit, is the hardware within a computer that carries out the commands of an app by performing the basic

  • arithmetical
    counting the number of mails
  • logical
    setting WiFi on or off
  • input/output
    playing music, or asking Siri via microphone

operations of the system.

The fundamental task of a CPU is to execute a sequence of stored instructions (a program). The instructions are kept in the memory. Usually CPUs work in 4 steps:

  • FETCH
    Fetch involves retrieving an instruction (a sequence of numbers) from the program memory. The location in program memory is determined by a program counter (PC), which stores a number that identifies the current position in the program.
    The instruction that the CPU fetches from memory is used to determine what the CPU has to do.
  • DECODE
    In the decode step, the instruction is broken up into parts that have significance to other portions of the CPU. The way in which the numerical instruction value is interpreted is defined by the CPU’s instruction set architecture (ISA). Often, one group of numbers in the instruction, called the opcode, indicates which operation to perform. The remaining parts of the number usually provide information required for that instruction, such as operands for an addition operation. Such operands may be given as a constant value (called an immediate value), or as a place to locate a value: a register or a memory address, as determined by some addressing mode.
  • EXECUTE
    During execution, various portions of the CPU are connected so they can perform the desired operation. If, for instance, an addition operation was requested, the arithmetic logic unit will be connected to a set of inputs and a set of outputs. The inputs provide the numbers to be added, and the outputs will contain the final sum.
  • WRITEBACK
    The final step, writeback, simply “writes back” the results of the execution to the memory. Some types of instructions manipulate the program counter rather than directly produce result data. These are generally called “jumps” and facilitate behavior like loops, conditional program execution (through the use of a conditional jump), and functions in programs. Many instructions will also change the state of digits in a “flags” register. These flags can be used to influence how a program behaves, since they often indicate the outcome of various operations. For example, one type of “compare” instruction considers two values and sets a number in the flags register according to which one is greater. This flag could then be used by a later jump instruction to determine program flow.

After the execution of the instruction and writeback of the resulting data, the entire process repeats, with the next instruction.
Scientists found out that a brain can also be divided into areas with special functionalities. But don’t ask me how this all works together within a human being and whether parallel execution of tasks is possible or not. Fact is that the processor cannot work on two different tasks as long as their is no companion processor which is designed to offload work from the main processor. The introduction of the M7 Motion processor in Apple’s iPhone 5S in October 2013 allows to aggregate all the data from different sensors of the device and deliver necessary data to the CPU if needed. So the device gets faster because work is partially done by two ‘brains’.

20131120-143425.jpg

The Sensors

In the skin, there are at least five different types of nerve endings:

  • heat sensitive
  • cold sensitive
  • pain sensitive
  • itch sensitive
  • pressure sensitive

All these senses submit reactions controlled by the brain, the many experiences stored there, and patterns which initiate reactions.

Your iOS device also needs the help of many sensors to work properly. For example, if you turn your device from portrait to landscape mode the operating system will also turn the screen of an app (if the developer implemented this feature). In contrast to human sensors, the device’s sensors always initiate the same actions if the input data are the same whereas a human being is able to react in different ways up to the actual needs, e.g. hearing a voice (the sound waves) but not processing the content.

Summary …

There are similarities but only in a figurative meaning. Human beings learn many additional skills and can change their reactions even if causes remain the same. An iOS device gets its skill when manufacturing is finished and can only expand them with the installation of an update of the operating system. Advantage human being. So keep control over yourself and do not delegate essential task to your device. Just use it for what it is intended for, show you the way with the app Maps, connect you to the giant sources of knowledge, and help you being creative by using a mind mapping tool.

Recovery

15 01 2014

When an iOS device encounters iOS- or app-related trouble, the issue usually can be fixed by

  • Restarting the app
  • Rebooting the device
  • Deleting the app and reinstalling it

But there are also circumstances where these actions don’t help.
Let’s start with the easiest and fastest way of solving a problem on an iOS device.

Reboot an iOS device …

To reboot means to discard all continuity in a running device in order to recreate its status and memory from the beginning.

Why do you have to reboot your device occasionally?

Rebooting is sometimes necessary to recover from an error, re-initialize drivers, or hardware devices. A reboot may also occur automatically if the computer or hardware device encounters an error or is overloaded.

The reason can be a hardware malfunctioning or, more likely, an application which does not manage the memory associated to it correctly by interfering with other parts of the memory reserved for other tasks.

20131024-191710.jpg

Think of it like this …

You want to send money to an a count and looked up the account number. Somebody asks you ‘What time do we have the appointment with Mr. Smith?’. After answering, your short-term memory containing the account number is deleted or the account number you are sure it’s right now contains transposed digits.

You have to reboot and load your memory again with the account number.

If you don’t look up the account number again your money transfer will fail. Regarding your device an app may execute an unwanted operation which might freeze it e.g. by running into an endless loop. You tap on a control but the app doesn’t react or delivers wrong information to the brain of your device, the processor.

Recovery Mode …

In some circumstances, though, the problems are more extensive and require putting the device into recovery mode and restoring it.
Recovery mode is also called DFU mode (Device Firmware Update).

DFU Mode is a state where an iOS device can interface with iTunes but does not load the iPhone operating system or boot loader (this is what really differs DFU mode from Recovery Mode).

The primary reason people need to access DFU mode on their iOS device is to change the firmware on the device. This can serve to downgrade to a prior iOS firmware and operating system, or to use a custom firmware that is required for a Jailbreak or SIM unlock.

You may need to perform a recovery-mode restore if you experience any of the following situations on your iOS device.

The device

  • displays the Apple logo with no progress bar or a stopped progress bar for over ten minutes
  • restarts but never displays the Home screen
  • is no longer recognized in iTunes after an update or restore did not complete
  • automatically goes into recovery mode after having an issue while installing an update or performing a regular restore

Reasons for this system behavior can be …

  • Broken connection while updating to a newer version of iOS
    – Computer to which the device is connected fails
    – Broken internet connection
  • Repairs that require you to erase all data on phone
  • Unwanted deletion of the device
  • Corrupted files

How to recover your device …

This brief manual applies to all iOS devices as there are iPhone, iPod touch, and iPad independent of their iOS version. I kept it brief and left out the clear-worded instructions messaged from iTunes and your device. They are all self-explaining.

What you need is your

  • iTunes backup password
    (if you use one)
    To use an iTunes backup password is highly recommended because only in this case the device restore includes all sensitive data like passwords for E-Mail accounts or websites.
  • Phone number
    (if you use an a SIM card in your iPad)
  • iTunes account credentials (Apple ID)
    (E-Mail address and password)

How to enter the Recovery Mode …

  • Connect Apple’s USB adapter (cable for charging your device) to your computer with an installed version of iTunes, but do not connect it to your iOS device.
  • Turn off your iOS device by holding down the sleep/hold button in the top right corner until the slider ‘slide to power off’ appears at the top. Slide it.
  • If your phone won’t respond to that, hold the sleep/wake button and the home button together until the screen goes dark.
  • When the phone is off, hold down the home button and connect the USB adapter to the dock connector of your iOS device.
  • The iPhone will turn on and display the Apple logo.
    Keep holding the home button until the screen shows the iTunes logo/USB adapter.

The iOS device is now in Recovery Mode.

If the red empty battery icon appears onscreen, let the phone charge for a few minutes and then restart this process.

When the phone is in recovery mode, a window will pop up in iTunes saying that the phone is in recovery mode and needs to be restored. You can either restore it to its factory settings or from a recent backup of your data.

20131024-194210.jpg

An example …

I set my iPad 3 (64 GB, Used space 21.5 GB, 224 apps) into recovery mode after backing up to iTunes. The total time of a restore was about *3 hours*.

About 20 of the 224 apps are frequently used and a greater amount of data is stored in their local folders. The other apps are just for tests and usually manage no data.

You can estimate the time for the total recovery process including the restore of data by taking the two parameters (21.5 GB and 180 min) into account.

(Your used space / 21.5) * 180 = time to recover and restore

The worst cases …

  • If recovery is not possible you have to contact an Apple Store or send your device to the repair service.
  • f you don’t have any backup in iTunes or iCloud resp. just an old one you will loose all your data resp. all changes since your last backup.

Failed attempts to unlock …

If the iOS device has been disabled from too many attempts at entering the passcode lock, then your device will be locked.

The only way to regain full use is to put the device into recovery mode and restore it via iTunes.

So in this case you must have access to a computer with an installed version of iTunes. There is no way to do it just with an internet connection.

Restore without iTunes …

If you don’t use iTunes, maybe you already moved into the Post-PC era, you can restore your device if it’s connected to a WiFi network.
An iOS device has a built in reset option programmed into the device itself. With the introduction of the iCloud service, you no longer need to connect the device to a computer to restore through the iTunes software.

Restoring an iPhone is useful if you’re going to sell the device or if you want to troubleshoot it after data has been corrupted.

Follow these steps:

A Backing up your iOS device

  • Step 1
    Connect to the Internet through a Wi-Fi connection. A typical iPhone backup can consume a lot of data.
  • Step 2
    Tap on the “Settings” menu item. Select “iCloud” and then “Storage + Backup.”
  • Step 3
    Tap on the button that says “Back Up Now” to cause the iPhone to back up its settings to iCloud, which may take several minutes to an hour or more.

B Resetting your iOS device

  • Step 1
    Tap on the “Settings” menu and then tap on “General.”
  • Step 2
    Scroll to the bottom of the menu and tap “Reset.”
  • Step 3
    Tap the button that says “Erase All Content and Settings.” The iPhone will ask you to confirm this choice. Press the button marked “Erase Phone” to restore your phone to its factory settings.

C Restoring from a backup

  • Step 1
    Start up your iPhone. On a freshly restored iPhone, you are prompted to use the Setup Assistant. Do this in a place where the iPhone is connected to a Wi-Fi signal. This can consume a lot of data.
  • Step 2
    Select “Restore from iCloud Backup.”
  • Step 3
    Enter your iCloud username and password information. Your iPhone will restart and begin downloading your backup from iCloud. You may be asked to choose from up to three backups on iCloud, sorted by date.

Reselling your device …

Before you resell your device follow these steps:

Method 1
You can remove all settings and information from your iPhone, iPad, or iPod touch by going to Settings – General – Reset and tapping on Erase All Content and Settings.

20131024-195605.jpg

If you wish to recover all your settings and data again on a new device, ensure that you have an iCloud or iTunes backup and that it’s up to date.

Newer devices running on iOS 5 and later support hardware encryption. Erasing the device means removing the encryption key that protects the data. This process takes just a few minutes.

Method 2
Use iTunes to restore your iPhone to factory settings.

Plug the phone into a computer running iTunes and wait for it to appear in the ‘Devices’ section of the iTunes sidebar. Select the iPhone from the sidebar and then make sure you’re on the “Summary” tab. Under ‘Version’ select ‘Restore‘. You’ll receive a pop-up dialog informing you that this step will erase your phone and reset it to factory settings. Click Restore to continue.
iTunes will now download the latest firmware for the iPhone, which may take several minutes depending on your connection speed. Once downloaded, iTunes will automatically begin the restore process during which your phone will reboot twice. After the process is completed, the phone will appear in iTunes as a new device and ask you for a device name. Before entering any information, disconnect the phone. It has now been wiped of your personal information and is ready for sale.

Summary …

Restore from a backup or even recovery of a device is usually a process you didn’t need while using your iOS device. Quality of hardware and software ensures that all what happens in the life of a computer doesn’t happen with an iPhone or an iPad.

Anyway your iOS device should regularly backed up to iTunes, or what is much more comfortable, to iCloud. Strongly recommended is the usage of an unlock code as well as a password for iTunes backups. If you don’t use passwords many sensitive settings like E-Mail account settings are not included in a backup. So you have to configure them all if the restore process is finished. That can be a pretty much exhausting task.

Blogging with iPad + iPhone

7 01 2014

No computer, no mouse, no keyboard, no cables, just an iPad, an iPhone. That seems to be a minimalistic configuration for blogging and doing all the other things where an electronic device is a bit more comfortable than a pen, sheets of paper, card boxes, and postage stamps.

This time I want to talk about blogging on WordPress, the biggest free blogging platform in the world, with a minimalistic configuration supported by Apple’s ecosystem.

The hardware …

I use this hardware configuration at home and the iPhone on-the-go and at home as a second screen.

The apps …

All mentioned apps are so-called ‘universal’ apps that means you download once from Apple’s AppStore and the apps are installed across all devices which are configured with the same Apple ID. All my apps are able to connect to cloud storages so that information can be accessed from the iPad as well as the iPhone when on-the-go. Additionally they keep the data in the local app folders, an indispensable requirement. WordPress, PlainText, iThoughts, and Keynote, the essential apps for blogging, save their files automatically in their local documents folder. This allows working even if an internet connection is temporarily not available. Syncing is automatically done if the iOS device reconnects.
Essential data are synced with Dropbox (supported by most of the apps in Apple’s app store) and additionally with Box to increase data security (redundant storages). Unfortunately Dropbox still doesn’t allow WebDAV access which is required when saving iWork documents on an other storage than iCloud. So my second cloud provider is Box (for personal use, 10GB free, perfect UI and features available in the iOS app, perfect content sharing platform, available since 2005). Box supports WebDAV so iWork documents can alternatively saved on Box from within all iWork apps by using the command ‘Copy to WebDAV’.

All apps are developed by reliable companies and offer regular updates and feature extensions as well as adaption to major changes of the operating system like Apple’s update of iOS in Sep 2013.

WordPress
The blog engine

20131020-063307.jpg

This app is used to finally create the textual and formatted part of a blogpost with added images or videos. It also manages the WordPress database where your posts are stored. Posts can be saved as drafts for further editing, published immediately (even via E-Mail sent to WordPress), or scheduled.
Powerful stats give you an overview of the number of visitors from each country, followers, referrers, search engine terms, top posts and pages, clicks, tags, and categories you assigned to your posts. Backups of the whole blog data can be made by exporting an the database contents as an XML file.

It’s recommended to activate Akismet (a subsidiary of WordPress) to keep your blog clean of spam comments.

Apple’s Keynote
Breath life into your posts

20140106-071108.jpg

There is no other comparable app for creating presentations on mobiles like Apple’s Keynote, part of the iWork Suite. With Keynote I create all the images you see in my blogs as well as images for social networks. Creating an image in Keynote is a funny task. Collages created with images (e.g. screenshots of running apps on your device), added text and symbols, varying opacities, and connecting lines breath life into your post.
And it’s all synced with your other iOS devices via iCloud.

iThoughts
Visualize your thoughts

20131020-063640.jpg

Take this mind mapping tool for brainstorming, feature descriptions, or all other kind of information which should be summarized visually.

Tap Forms
Keep it all together

20131020-063816.jpg

Using a database is the right way to keep different information together. With Tap Forms I manage all posts, post intros for sharing on social networks, images, and links. This is also done automatically by WordPress but the iOS app lacks because some useful features covered by my database are only available via a browser which, in some cases, is a quite painful way to access essential information about posts.

PlainText
Back to the roots

20131020-063942.jpg

Don’t care about formatting. This can be done later. Content is essential and content doesn’t need bells and whistles but a running brain. To keep the mobility the editor should be connected to a cloud storage so that editing can be continued anytime, everywhere with one of the two devices.

PlainText is connected to the cloud storage Dropbox as well as iCloud and automatically saves edited text in the cloud. Just write what’s in your mind, the rest is managed by the app. As an alternative I recommend the app ByWord which supports Markdown. The app can be updated so that text can easily posted to WordPress, Tumblr, Blogger, Scriptogram, and Evernote.

Note (1)
Simple text editing for users aged from 4-104.
The first text editors were Line Editors oriented to teleprinter- or typewriter- style terminals without a display. On some line editors, the cursor could be moved by commands! Line editors drastically improved text editing. In 1982 the Personal Editor was developed for PC DOS, the IBM operating system for their first personal computers like IBM PC, XT, or AT.
Limitations in Personal Editor led to the development and release of the E-Editor (E.exe) in 1984, a much faster editor that supported very long files and included a substantially enhanced user interface.
The story of the E-Family began and has not yet ended.
Simple editors are still in vogue because

  • the application loads within a blink
  • there is no need to learn how to use it
  • the file format (txt) is readable by all machines and applications
  • most of the simple editors sync automatically across iOS devices

and
are a perfect way to quickly write down a basic idea for further platform-independent usage with all other apps like an E-Mail client, a grown-up word processor like Apple’s Pages, or a mind mapping tool like iThoughts.

Note (2)
Markdown is a plain text formatting syntax designed so that it can optionally be converted to HTML. Markdown is popularly used as format for readme files, or for writing messages in online discussion forums, or in text editors for the quick creation of rich text documents. Markdown works with special characters like *italic* or **bold** to format text as italic or bold.
There is no clearly defined Markdown standard, apart from the original writeup and implementation by John Gruber, which is considered to be abandonware, leading to fragmentation as different vendors write their own variants of the language to correct flaws or add missing features.

Prizmo
The text recognition engine

20131020-064100.jpg

Sometimes it’s worth to take a quick screenshot of an information. Then, if you want to quote, you need a text recognition application which allows to convert an image into text. The far best app is Prizmo. Prizmo supports syncing via iCloud so that screenshots or photos made with the iPhone are also available on the iPad to extract text later.

AIO Remote
The document manager

20131020-064610.jpg

Sometimes it’s necessary to scan documents (e.g. invoices of charged accounts, …) with the AirPrint capable HP printer or copy them. The app also provides file management. The HP printer can be fully controlled by the app.

Google+
The content network

20131020-113112.jpg

G+ for iOS devices let you publish links to your WordPress blogs on Google+ to quickly extend your audience when posting to appropriate communities.

FileBowser
The data management tool

20131020-114652.jpg

The best app to manage files on cloud storages as well as computers is FileBrowser by Stratospherix, now also supporting Point.IO. By using a VPN connection you can access storages of remote computers in your office. FileBrowser supports the display of Microsoft Office files, Apple iWork files, PDF files, and other well-known formats.

Additional apps
Various tasks

For other related tasks the software configuration can be extended by TeamViewer Remote Control (managing the still indispensable Windows PC in the office) and further apps which connect you with other social networks like LinkedIn, Pinterest, Scoop.it, Path, Tumblr, StumbleUpon, Twitter, and Facebook. An additional useful app is the free version ‘PS Express’ by Adobe for some basic editing of images.

Blog articles with high quality require intense researches to enable readers to validate your content and for quoting content of other authors. This can be done by using the mind mapping tool iThoughts with it’s integrated browser or by saving links as bookmarks in Safari using a special folder like ‘BlogResearch’. Doing it with iThoughts is the more convenient way if you create the blog structure already with a mind map.

The whole configuration …

Made with iThoughts for the iPad here is a summary of all compontents I use for blogging.

20140506-091341.jpg

If you use a mind mapping tool you can benefit from links assigned to topics. These topics are marked with a small globe. Tapping on a topic opens the website within the integrated browser of iThoughts without switching to the standard browser.

Feel free to download this mind map.

The alternative file formats have been created with iThoughts HD for iPad (.ITMZ file format). Compatibility to other tools is limited. The DOCX file format is suggested for those who don’t use a mind mapping tool. The file contains the image as well as a detailed outline of all topics.

Summary …

It works but admittedly it would work also with a cheaper configuration when using Android devices. But the price is often not the one and only criterion. In my case it’s the homage to a great visionary, an innovator, and a top influencer of our times.

It was Steve Jobs who forced me to join Apple’s ecosystem and start blogging about this fascinating company and the much more fascinating people who made Apple to the most valuable and innovative company in the world (Forbes 2013).

The only task which cannot be done with an iOS device is uploading of files to websites like BIGGERPLATE, the mind mapping platform.
