iTunes 11 File Sharing

30 11 2012

iTunes 11 is released.

The Dinosaur-App has got a fresh new design.
I am not a DJ and use iTunes only for backing up my devices and saving files via File Sharing to a local harddrive.

So my rating of iTunes 11 is a bit different from others.
See, why it does not suit my requirements …

The good news is …
(quoted from Christian Zibreg on iDownloadBlog.com)

iTunes 11 does not exactly mark a fresh start for the decade-old app, it truly delivers important enhancements while de-cluttering the interface and introducing under-the-hood tweaks.





Linking sheets in NUMBERS

29 11 2012

If you want to link various sheets in Apple’s iWork-App NUMBERS here is an example how to do this.

You may download the sample in the native NUMBERS-Fileformat.

Properties EN .Numbers iDrive
Alternative Download from Dropbox

The essentials in brief …

  • 1 Tap on the cell in the destination sheet you want to link with a cell in the source sheet.
  • 2 Tap on ‘=’ for creating a formula.
  • 3 Tap on the small ‘Down Arrow’ on the right side.
    The sheets come up for selection.
  • 4 Select the sheet and cell containing the source data.

Creating formulas with linked data works in the same way as in a standalone sheet.
The only difference is that you have to select the sheet (Step 2) before you refer to cells of it in your formula.





S/MIME Secure E-Mail communication

27 11 2012

If you want to communicate via E-Mail in a secure way, activate S/MIME for your E-Mail-Account in the settings of your iOS-Device. S/MIME was first introduced by Apple in iOS 5.

The problem …

Maybe you experienced an E-Mail from a friend where the subject line seems a little odd. Upon opening the E-Mail you noticed that it was SPAM. Somehow a spammer was able to use your friends E-Mail address (spoofing an address) which, understandably, made you feel comfortable enough to open and read the message. These experiences forced the need for having a more secure form of E-Mail.

If you send a letter through the post office do you simply print a piece of paper and drop off in a mailbox, or do you put it in an envelope? If you are worried about people reading your message, why do you send an email without a ‘virtual envelope‘? As an email passes through routers, switches, and from one mail server to another without it being inside a virtual ‘envelope’ (thus encrypted), anyone could look at your letter.

How it works …

Secure/Multipurpose Internet Mail Extensions (S/MIME) can secure your mail by encrypting a message at the source and only decrypting it once it’s in the hands of the receiver. S/MIME also supports digital signatures, so you can know for sure who sent the message and that it wasn’t changed in transit.

If S/MIME is activated the iOS-Mail application will show a little checkmark (within a gearwheel) after the sender’s name if a message was signed.

If something is wrong with the certificate or the message was changed after it was signed, iOS-Mail displays the senders name in red followed by an open padlock.

A common reason for signature failures is people using self-signed certificates or using CAcert, which isn’t considered a trusted authority by Apple and others.

The bad news is that you normally have to pay for a Digital ID from a Certificate Authority (CA) e.g. VeriSign.

If certificates are cheap (or even free) the certificate authority only checks whether the person requesting a certificate is actually in control of the E-Mail address in question, with no actual identity checking.

What you need …

A Class 1 Digital ID e.g. from Symantec/VeriSign.

The process from APPLY to INSTALL …
20121113-110418.jpg

How to install …

  • Apply for a Digital-ID.
  • Wait for confirmation and issue. It may last up to several days depending on the verification strategy of the CA.
  • CA issues your digital certificate for installation on a PC/Mac.
    Follow the instructions of CA, when you get the download link for your certificate.
  • Install the certificate in the certificate storage of Safari/Internet Explorer.
  • Export it using file format PFX.
  • Send the PFX-File as an attachment to the appropriate E-Mail-Account (the account the certificate was applied for).
  • Open it on your iOS-Device and tap on the attachment (PFX-File).
  • iOS identifies this format as an importable Identity Certificate for installation as a Profile. Follow the instructions. Pay no heed to any strange message.
  • Turn on S/MIME-Option.
    Two additional sections (Sign, Encrypt) will be displayed.
  • Turn on Sign and Encrypt.
    You can select one of the certificates you own a private key for. Clicking it puts a checkmark next to it and this is the certificate that will be used to sign all outgoing messages from this account.

How to communicate securely …

  • Send a Mail to the recipient.
  • The Recipient must install your certificate (by tapping on the sender’s name) for future secure communication.

Additional information …

  • Apple has chosen to not indicate that a message was signed in the standard configuration under iOS. To enable this feature, you have to go into the Settings… Account… Advanced for each E-Mail-Account, and then enable S/MIME. If you have other iOS-Devices you have to repeat all steps for every device.
  • Recipients will get an attachment smime.p7s if you send an E-Mail with your certificate. This attachment can be ignored.
  • iOS doesn’t automatically store the certs of people who sent a signed E-Mail to you. Instead, when someone has sent you a signed message, you have to tap the sender’s name and then you can install the certificate for future use. If you try to send a message to someone you don’t have a certificate for while encryption is enabled, their name turns red to alert you to the problem. A lock icon indicates that a message was encrypted.

Using an iPhone in Thailand

25 11 2012

3G is now widely available in Thailand.

Here are some notes about using an iPhone in a small village about 7 kms away from Khon Kaen in the northeast of the country.

The iPhone-Configuration …
iPhone 4S, 64 GB, 3G-Internet-Connection via provider DTAC, Temperature 86-95 F (30-35 C)

  • WLAN OFF
  • Bluetooth OFF
  • iCloud ON
  • Location Services OFF
  • Push-Mail OFF
  • Push-Notifications OFF
  • Brightness 25%
  • Auto-Brightness OFF
  • Manual lock after usage

With this configuration and normal usage of the 3G-Connection (estimated 1h/day) and no calls the remaining battery power was at 40% after 10 hours.

It’s hard to say wether the device has higher battery drain in Thailand than in countries with lower average temperature because there are so many factors affecting it.

As I did not drop my habits using the device in Thailand it seems to me that there is no significant difference.

To be on the safe side I use the ‘Mophie Juice Pack Powerstation mini’ (Mophie 2.500 mAh / iPhone 4S 1450 mAh). Recharging is fast (1%/min) and may be applied 2 times a day if the device is charged to 80%.

The human brake …
Clammy fingers are like brakes when using gestures like drag, flick or pinch.

Wouldn’t this be a good idea for a new accessory available in Apple’s Store …
The Fingertip-Cooler?
How it should work …
Use Wireless-Fingertip-Connection to connect to your finger, go to SETTINGS and adjust the temperature or use the ‘Auto-Temperature’ feature.

The speed …

A suitable offer …

DTAC Internet and Voice package

Converted rate for an unlimited access per month with speed limitation to 64 KBit/s after 1 GB data transfer …
427 Baht = 13.90 $ (10.79 €)
If the limit is reached you will get an SMS. It contains the dial-up *104*50# with which you can activate the ‘3G BOOSTER’ for 150 Baht (4.88 $/3.76 €) with 1 additional GB for 1 month.

How to get a SIM-Card …

Nearly all shopping malls (Tesco Lotus, Big C, MBK, …) offer Prepaid SIM-Cards. An alternative is to buy it directly at the Suvarnabhumi-Airport on arrival. There is a DTAC-Office at Arrival-Floor.
Register on the DTAC-Website for controlling your balance from outside the country.
The validity of prepaid SIM-Cards is limited. Every time you refill your account the validity is extended (150 Baht (4,88 $/3.79€) – 1 month). If you often visit the country and want to keep your number you may extend the validity up to 360 days for just 2 Baht/30 days.
You can do this by E-Mail short before your card expires. As an alternative dial *113*days# with days = 30, 60, …, 360.

Staying in the country you can refill your account at all shopping malls, 7 Eleven and in many small kiosks. After successful refilling you will get an SMS which contains the remaining call-credit and the expiration date.

Here are some useful dial-ups …

*102*9# your mobile number will be displayed
*101*9# view remaining credit balance and validity date
*101*4*9# view remaining internet credit balance and used data transfer volume
*104*50# order 3G Booster, which gives you extra 1 GB data transfer volume with 3G speed for 30 days

Have a nice trip and enjoy the delicious food and fruit.





Changing the layer of images

22 11 2012

In Apple’s KEYNOTE (part of the iWork-Suite) text and images are allocated in layers.
There is an easy way to change the layer of overlapping text and images.

You only have to use cut and paste in reverse order to permute the layers.
Here is an image which explains the procedure shortly.

Bugfixing for DATEDIFF(…)

20 11 2012

An error occurs in Apple’s iWork-App NUMBERS when using the DATEDIFF-Function. This function determines for example the number of days between two dates.
The bug occurs, if argument 2 is greater than argument 1 in DATEDIFF(arg1, arg2, “D”).

The downloadable .numbers-Document explains how to fix this bug using the ISERROR-Function.

Shortcuts

16 11 2012

Reduce the effort of typing frequently used text blocks.

On iOS-Devices people interact with one app at a time. This app is presented in a single window. So the best practice is to use built in features of iOS for text editing.
Then there is no need to switch between the app you are currently working with and any additional app like TextExpander.

Setting up your iOS-Device with shortcuts …

20121111-122405.jpg

Further examples for shortcuts …

  • E-Mail-Signatures
    If you use the iOS-Mail app you can set up signatures for all of your accounts (‘Per Account’-Option). If you want to use a different signature from time to time you can use shortcuts.
  • Different Salutations

Benefits of iOS-Shortcuts …

  • Shortcuts are available in all apps
  • Shortcuts are synced with all of your other iOS-Devices via iCloud.
    Just go to Settings… iCloud and turn on ‘Documents + Data’.

Special for WordPress users …

If you use the app WordPress or post by E-Mail create shortcuts for …

  • a table e.g. with 2 columns and rows
    (required arrow brackets were replaced by braces)
    Shortcut
    wptable22
    Phrase
    {table border=”0″}
    …{tbody}
    ……{tr}
    ………{td}A 1{/td}
    ………{td}B 1{/td}
    ……{/tr}
    ……{tr}
    ………{td}A 2{/td}
    ………{td}B 2{/td}
    ……{/tr}
    …{/tbody}
    {/table}
  • WordPress shortcodes for properties of the post in the E-Mail body e.g.
    Shortcut
    wpmail
    Phrase
    [category Shortcuts]
    [tags … iOS, Usability]
    [status … draft]
    [title … Shortcuts]
