Screen and Audio recording on macOS & iOS

February 28, 2018 / Arun Patwardhan / 3 Comments

In this article we are going to look at how we can use the built in Application: QuickTime to record a screen or a movie. In fact, the videos that you are about to see in the article below were created using QuickTime.

A good reason to record the activity on the screen would be to create a visual step by step guide which can be distributed to employees in the organisation. For example, you can create a video to show employees how they can sign into their company’s email account and access it from their iPhone or Mac.

Recording your Mac’s screen

Follow the steps given below to record your Mac’s screen:

Open QuickTime Player
Click on File > New Screen Recording
You should see the window popping up.
From the drop down next to the Record button select the audio input & whether mouse clicks should be shown.
Click on the Record Button. You should see a dialog asking you whether you want to record a small area or a full screen.
The recording starts once the stop button in the menu bar becomes dark.
Click on the stop button to stop the recording.
Save the file that was created.

Recording your iPhone/iPad Screen

(Mirroring your iPhone Screen on the Projector)

The process of recording the iPhone/iPad screen is quite similar to recording your computer’s screen. The key thing to remember is to connect your iPhone/iPad to the Mac with the lightning cable.

Follow the steps given below to record your iPhone/iPad screen:

Open QuickTime Player
Click on File > New Movie Recording
You should see the window popping up.
From the drop down next to the Record button select the audio input & whether mouse clicks should be shown. The difference now is the fact that you get an extra option to choose the source.

Recording a Movie

Follow the steps given below to record a Movie on your Mac:

Open QuickTime Player
Click on File > New Movie Recording
You should see the window popping up.
From the drop down next to the Record button select the audio input. You can also select your camera source from here.
Click record to start recording & click on the stop button to stop recording.

Recording Audio

Follow the steps given below to record an Audio on your Mac:

Open QuickTime Player
Click on File > New Audio Recording
You should see the window popping up.
From the drop down next to the Record button select the audio input.
Click record to start recording and stop to stop recording.

Here is a quick video on how to perform the different tasks that we have seen above.

Buyers Guide for macOS & iOS in the Enterprise

November 20, 2017 / Arun Patwardhan / Leave a comment

This article is more of a productivity article aimed at getting first time users up and running quickly on their Mac, iPhones or iPads. Anyone looking to buy one of these products or Tech Support teams that help employees with their computers would find this article helpful. The thoughts shared here are personal, readers are welcome to share their own thoughts and experiences.

The article is not a comprehensive guide. Its aim is to give potential users some idea as to how the devices can be used in their work environment. Specifically from an Application perspective.

Macintosh

Which one to buy?

This depends on how the device is going to be used. Here are 3 general classifications:

Basic Usage

Basic usage would mean simple day to day tasks. These are the tasks that would qualify for:

Checking emails
Browsing the web
Social Media
Listening to Music
Watching Movies
Composing letters
Preparing Presentations & running presentations
Note taking

In such a case you may want to consider buying a MacBook or a MacBook Air. If portability is not required then a Mac Mini would also do.

At entry level configurations these devices would do the job very well.

Intermediate Usage

If the tasks being performed are a little more demanding then you may want to consider higher configuration devices. Again in most cases the MacBook or a MacBook Air would do. If portability is not required then a Mac Mini would also do. In all these cases consider one with slightly higher configuration.

For situations where the compute power is important you may even consider the MacBook Pro. For example, if there are programmers who need to work with a high configuration Mac and they need portability, then you can consider the MacBook Pro.

Pro Usage

This indicates that the tasks being performed are very compute intensive. These are some of the job profiles which may demand compute intensive resources:

Programmers
Video Editors
Audio Editors
Post Production Teams
Marketing & Creative Teams
Scientific Research

For such situations the higher end desktops & MacBook Pros would be required. So the iMac or the highest configuration Mac Mini, or the 15″ MacBook Pro would be best suited for such environments.

In some situations even more powerful computers would be required. The iMac Pro & Mac Pro should then be considered.

Built In Applications that might be useful

Productivity Tools

There are 3 applications which are a part of the suite called iWork that are very useful in organisations.

PAGES: Built in word processing application. You can easily created documents, letters, reports and even have them exported in Microsoft Office compatible format.
KEYNOTE: Built in presentation applications. Enables you to create powerful presentations from scratch. Like Pages it is possible to create presentations that are compatible with PowerPoint.
NUMBERS: Built in spreadsheet application. Enables you to quickly create spreadsheets and export them to Excel if needed.

The other advantage is the fact that these applications are also accessible from the cloud. Tight integration with iCloud means that you can make changes to documents from your Mac, iPhone, iPad, or iCloud.com.

Creative Tools

There are 2 applications which are available for creative purpose. These might be handy for people working in the creative departments.

IMOVIE: Quick create movies using videos, audios and photos that you have.
GARAGEBAND: A simple Music creation application that comes with a library of different instruments.

Popular Third Party Applications

These are just some of the applications.

Office Suite

Productivity

Cloud

Creative

Security

Communication

Data Backup

Virtualisation (Running Windows or Windows Applications on the Mac)

Some tasks that can be done with built in Applications

Scanning Documents using Preview
Signing Documents using Preview
Record Screen Activity using QuickTime
Record a quick movie using QuickTime
Automate Tasks & create workflows using Automator
Encrypt Data using FileVault
Show your iPhone/iPad screen on a projector using QuickTime on Mac
Backup data using Time Machine

iPhone/iPad

Which one to buy?

The decision on whether to buy the iPhone &/or the iPad depends a lot on what you intend to use it for. As such the major differences between the 2 devices are:

iPads tend to have larger screens
iPhone has cellular communication capability
iPhones are more portable as compared to iPads
iPads are better suited for long duration usage
iPads tend to be higher powered devices

While it appears that iPads are better than iPhones, that is not necessarily the case. iPhones being smaller and more compact have many advantages too.

Ideally speaking having both, an iPhone and an iPad, is the best thing to do.

To make a decision use the task list below to help find out if you need an iPhone or an iPad or both.

Note, even though I mention that the tasks can be performed easily on an iPhone, many of the tasks can also be done very easily on the iPad. The point is to illustrate ease of use in situations where you have to perform tasks with a single hand or when you are on the move.

Tasks easily performed on an iPhone

Making calls
Messaging
Scheduling activities such as: Reminders, Appointments, Events
Taking Photos & Videos
Emails
Banking Transactions
Finding Transit Directions
Finding a Taxi
Making E-Payments

Tasks easily performed on the iPad

Writing letters & blogs
Creating Presentations
Working with spreadsheets
Creating posters, flyers
Working with business applications
Content creation

If you do a mixture of tasks from both the lists then getting both an iPhone as well as an iPad is a good idea.

A thing to keep in mind is that the Pro version of the iPad also has a nice keyboard accessory as well as the  Pencil available. These 2 products make the whole experience so much better.

Screen size consideration

iPhone and iPad screen sizes vary quite a bit. Here are some tips on the tasks which can be best performed on specific screen sizes.

Creative Work

Generally speaking, creative tasks require a large screensize. So for an iPhone the smallest screen you should have is 4.7″. Similarly for the iPad the smallest screen you should have is the 9.7″.

Documents, letters, spreadsheets

These tasks are better performed on the iPads as such you can go for any screen size in them. Of the lot, its a lot easier to create documents and letters on the phone than spreadsheets. Again, for phones one should the larger the screen size the better.

Presentations

Like documents and spreadsheets presentations are a lot easier to create on the iPad. They can also be created from the phones. The larger the phone the better.

Messaging & Communication

This is one aspect where the screen size is not so much of an issue. In fact, some users may find the smaller screen size a lot better. Typically, the iPhone is a much better device than the iPad for this.

Productivity & General Tasks

This includes calling taxis, ordering food, taking notes, control keynote presentations, setting up appointments and reminders. These tasks are also best performed on iPhones. They can be done well with the iPad too.

Built In Applications that might be useful

Productivity Tools

There are 3 applications which are a part of the suite called iWork that are very useful in organisations.

PAGES: Built in word processing application. You can easily created documents, letters, reports and even have them exported in Microsoft Office compatible format.
KEYNOTE: Built in presentation applications. Enables you to create powerful presentations from scratch. Like Pages it is possible to create presentations that are compatible with PowerPoint.

Create PDF documents through pages & then edit the PDFs either through iBooks or markup utilities
Record and Edit videos using the camera & iMovie

Useful iPad Accessories

 Pencil *Works only with iPad Pro
Smart Keyboard *Works only with iPad Pro
Lightening to VGA Adapter
To connect to wired ethernet use 2 two adapter combination:
- Lightning to USB 3 Camera Adapter
- Belkin USB-C to Gigabit Ethernet Adapter

 TV

There are a few things that can be done with the  TV. It can be used to mirror both macOS & iOS Devices. In which case apps such as Reflector are not really required.

It is very easy to setup and use. This can make projecting both the iPad screen as well as the iOS Screen very easy & it allows you to move across the room as you are not physically wired to the projector.

Final Word

As we can see there are a wide variety of apps available both for macOS & iOS. These include built in apps as well as Third party apps. The community of developers creating these apps is strong and growing. There are many more apps which can be used for a wide variety of purposes.

This article should give the user a fair idea as to the capabilities of devices such as iPads, MacBooks and the rest of the line up. The good thing is that for enterprise environments its easily possible to create apps that are tailored to the needs of that organisation and this makes the devices much more attractive.

Programming Style Guide: Naming Conventions

September 21, 2017September 21, 2017 / Arun Patwardhan / 2 Comments

Today we are going to look at Naming conventions you can follow while writing code.

Naming conventions lay down the basic rules for naming different elements in your code. The objectives are simple:

Make the element easy to read
Should be self explanatory
Should contain information in a compact and concise manner.

Ideally a well named variable or function should not need a comment to explain what it is for.

With the above objectives in mind let us look at some of the naming conventions that can be followed. The examples are from the Swift & C++ programming languages.

Naming Conventions

Camel Case Names

In camel case naming convention the entire name of the element is constructed by forming a sentence joined into a single word. So for example if we have a variable for keeping track of the price of oil in US dollars then the variable name might be priceOfOilUSD.

Here are some examples of naming conventions with the camel case.

SWIFT

var priceOfOil : Float = 23.49

C++

float priceOfOil = 3.45;

class PersonInfo
{

};

Underscore Separated Names

In the underscore separated naming convention the entire name of the element is constructed by forming a sentence joined together with the help of underscores in-between them. So if we take the example of the variable keeping track of the price of oil in US dollars the the variable name might be price_of_oil_usd.

Swift

var price_of_oil : Float = 45.71

C++

float price_of_oil = 99.87;

void print_value_of_pi()
{
     //print something
}

Names with type information

A naming convention that is quite popular is the one that mixes the previous 2 naming conventions, with the underscore used to separate the type description in the prefix. So if we take the example of the variable keeping track of the price of oil in US dollars then the variable name might be f_priceOfOil or float_priceOfOil. Either of the design styles work. The prefix is popularly abbreviated and you can create your own rules for abbreviating the type description.

This style is often referred to as the Hungarian notation. The additional information that is provided as a part of the prefix can be:

Whether the variable is a pointer
Whether the variable is an object
The scope of the variable
Type size
Whether the data can vary or is a constant
…

Swift

var f_priceOfOil : Float = 0.0

C++

float f_priceOfOil = 22.3;

int *ptr_memmoryBuffer = NULL; //ptr indicates variable is a pointer

Naming Rules

There are some rules that are typically followed while designing names for variables and functions. Like the conventions themselves the rules are not binding but they are very useful an give the added punch that naming conventions provide.

Variable names always start in lower case.
Type names always start in upper case.
The naming conventions is consistently applied through all the projects
Names should be kept as small as possible without sacrificing on the description

Naming Strategies

As far as strategies are concerned there are multiple approaches that one can follow. Here are some potential strategies.

Follow one naming convention for variables and another convention for functions.
Let constants be all upper case
Prefix types with your companies initials.

Summary

The above illustrate just some of the naming conventions that can be followed. By no means are they comprehensive or complete. Also it is not necessarily true that everyone follows the above naming conventions. You may find that many software development firms have their own unique naming convention. This article should give you an an idea about naming conventions. Feel free to share some naming conventions that you have come across.

macOS & iOS IT Tool List

May 18, 2017July 28, 2019 / Arun Patwardhan / Leave a comment

This list is based on questions that I have been asked by various IT admins.

It is more of a collection of tools (mainly software, but a few hardware tools too) that Enterprise IT Teams might find useful while supporting/managing Macs & iPhones in the enterprise. Some of the tools are free, while others are paid. Also, it is not necessary that all the tools will be required. Of course, some tools are not meant for troubleshooting but provide a service themselves.

The below list is not an endorsement or recommendation of any of the products mentioned. These are just some of the products I have come across. You may have to do your own research to see which tool fits your organisation’s needs. The author is not responsible for any damages or loss of data that might occur from usage of these tools.

*This list is not a complete list but an ongoing project. Feel free to share your comments on tools that you may have used & I will add them to this list.

Creating multi-OS Install Disk

April 17, 2017 / Arun Patwardhan / 1 Comment

In this article we are going to look at how to create a multi-OS Install Disk. We are going to look at the example of creating a multi-OS Install Disk for the following versions of the OS:

10.9.1
10.10
10.10.4
10.11.5
10.12
10.12.1
10.12.2
10.12.3

The idea is to have a single disk with multiple versions of the Install Disk on it. The versions should reflect the need of the organisation.

REQUIREMENTS

USB Drive at least 75GB in Size. This depends on the number of Install drives you wish to have. At the very least there should be enough space to create 2 partitions of 8 GB each.
While I have mentioned USB drive, it need not be restricted to that interface. You can use Thunderbolt, FireWire or even an SDXC slot for this. Ideally the port should be one that is supported on maximum possible computers.
Install setup for each version of the OS for which you want to create the install disk. The setup must match the version desired.
A Mac running the same major version of the OS. You can only create an install disk for 10.9.x on a Mac running OS X 10.9.x, the same applies for the other versions of the OS.

The process is the same. It’s just that it needs to be repeated.
