Apple rolls back Camera Roll

For those of you who were shocked seeing photos deleted from your iPhone after the iOS 8 update, you just got tricked by Apple. You would have figured that out by now.

With iOS 8.1 your Camera Roll makes a victorious return. If you have enabled your iCloud Photo Library, the 'Camera Roll' will be replaced with 'All Photos'.

Clean App Switcher in iOS 8

You see recent and favorite Contacts in App Switcher after upgrading to iOS 8. Wish you could take them down? Follow along!

When you double click your home button, you see your recent apps which you can quickly switch between. With iOS 8 you also see avatars of your most recent and favorite contacts.

This feature is useful, but if you like it clean, you can have your way.

To disable your contacts from displaying in the app switcher -

• Launch your Settings app
• Select Mail, Contacts, Calendar
• Under Contacts section select Show In App Switcher

Toggle the switch to disable your recent, favorites, or both contacts.

WhatsApp reveals shared media in a slide

This is a little less known feature I recently discovered on iOS 7 (iOS 8 is round the corner).

To see all media (images / videos) shared between you and your friend or group, one can of course

• Open the friend's (or group's) chat window
• Click on the friend's (or group's) name on top
• Click on View All Media

The quicker way is to slide your finger from left to right on a particular friend (or WhatsApp group) from your chat list and you directly are in the View All Media screen.

WhatsApp: Difference between Broadcast Lists and Groups

and how to use them appropriately?

Broadcast Lists in WhatsApp

The Broadcast feature lets you send a message to many of your friends at once, without revealing the recipients to one another and each recipient then has the option to respond to you individually.

What more? You can now create Broadcast Lists and save the list of contacts to whom you send Broadcast Messages. Broadcast Lists are saved lists of message recipients that you can repeatedly send Broadcast Messages to, without having to select them each time.

Note: In order to be able to send a Broadcast Message to a specific contact, that person must have your phone number saved in their address book. Just a way to avoid Spams.

Groups on WhatsApp

Groups on the other hand creates a common space where up to 50 participants can be added to chat and collaborate together.

• A maximum of 50 participants can be added to a group you create.
• You can create a max of 50 groups.
• Every group in WhatsApp has a group admin. If you create a group, you are the admin by default. Only the group admin can add people to the group chat.
• As a group admin you can control the participants in the group. If a group admin leaves the group, WhatsApp will randomly assign an admin to a remaining group participant.
• As a group member you can control your own participation in a group chat. You may wish to stay or leave the group when you wish.

WiFi calling on Apple iPhone 6 & iPhone 6 Plus

You will be able to make regular calls to people over a WiFi connection if and when you have a poor network reception.

What is WiFi calling?

WiFi calling uses WiFi to enable voice and SMS to provide better mobile phone coverage in low cellular reception areas.

How does it work?

Moving past the technicalities, WiFi calling is a phone related feature which can be enabled by navigating to Settings / Phone / WiFi Calling and toggle the switch to ON.

Benefits?

• Voice and SMS over WiFi
• Improved battery life since it's only using one radio connection
• Hop from one network to another seamlessly. Start a call over WiFi at home, then step outside and the call will switch to your cellular network automatically and seamlessly without disruption.
• Hi-def audio calling.

How would calls be billed?

This is going to be operator specific and we will need to wait to hear more on this technology and service plan parameters. 

Will this work anywhere in the world?

I wish this was a good news but this is only supported by selected operators around the world yet. Several operators around the world have WiFi calling services, including T-Mobile US, Orange UK and Rogers Wireless in Canada. We will have to wait until Apple ends up with a deal with Etisalat or Du in UAE or other operators around the world.

Is it iPhone 6 only feature or will it support all iOS 8 enabled devices?

9to5mac.com says "WiFi calling is one of several new Phone-related features in the pipeline for iOS 8."

gizmodo.com says "You'll be able to call people using your WiFi connection on the iPhone 6."

appleinsider.com says "T-Mobile confirms support for Wi-Fi calling on iPhones running iOS 8."

I guess it's a matter of time when we'll clear the hazy air.

Increase your iPhone 5 battery life

Here are some less known options (may be obvious) to improve your iPhone 5 / 5s battery life.

Turn off Location Services

You might only need this on Google Maps to help you with navigation. Other than that I don't see much use of it on any other app. Many use the check-in facility on Facebook but caution here, Facebook location service is a battery hog.

• Settings / Privacy / Location Service - Turn of for as many apps as possible.

Don't kill multi-tasking Apps

It turns out that the work your phone does to reload these apps into the phone's RAM is more draining on the battery than keeping them in the RAM if they are already there. iPhone does a good job of managing what is actually running. Seeing these apps on double-clicking the home button doesn't actually mean they are running.

Turn off AirDrop

Swipe your finger from the bottom of the screen, click on AirDrop and select Off. When you're not using it, its best to turn it off.

Turn off Automatic Timezone

Unlike some your daily commute might not span different time zones. You can turn this feature off and manually change it to the new timezone.

• Settings / General / Date & Time / Turn off Set Automatically

Turn off Background App Refresh

Turning off as much of the Background App Refresh as possible is a good idea.

• Settings / General / Background App - and turn off as many apps as possible, or all of them.

Turn on Auto-Brightness

In the midst of all the turn-off(s), here is something you can turn on. iPhone does a good job of adjusting the brightness so that it isn't unnecessarily bright when it doesn't need to be. The display is one of the most power consuming facet of your phone.

• Settings / Wallpapers & Brightness / Auto-Brightness On

Turn on Reduce Motion

This will take away some of the pretty animations in iOS 7, but I'm just staying true to the purpose of the post.

• Settings / General / Accessibility - and turn Reduce Motion to 'On'

Command to connect to Oracle DB

sqlplus "/ as sysdba"

How do you know your TNS Entry in Oracle?

I'm just consolidating what I found from various other web pages. It's easier to refer to than looking all over the web.

tnsnames.ora file in Windows can be found at:

%ORACLE_HOME%/product/11.2.0/dbhome_1/network/admin

Since I'm no genius in Oracle, I had to look for the ORACLE HOME directory. You would need administrative access to the server or PC since you need to fetch this from the registry.

• Open Start > Run > regedit
• Navigate to HKEY_LOCAL_MACHINE / SOFTWARE / ORACLE / KEY_OraDb11g_home1
• You will find a key ORACLE_HOME and it's value would contain the path
