5 Misconceptions About Mobile Software Development

Reading Time: 4 minutes

The world of making mobile apps is exciting! For many, it is a new marketplace. A place of new opportunity and possibility. All of these things are correct, but mobile software development needs to START with the right thinking or your competition will beat you to market.

If we were working together on this app, there are a few things I’d have to make sure you know. Each of these is important. The right decisions can make sure users are engaged and know what to do. The wrong decisions can result in confused customers and lead to people uninstalling the app just as fast as they downloaded it.

Mobile and web development are the same

Everyone is familiar with websites and web pages these days. Think about it. Who hasn’t seen amazon or online Tax Software these days? So it is easy to assume that web and mobile development are the same. However, from the start, even the screen size changes the goals and viable choices in mobile development.

Your goals for each page become more directed and simplified. Accomplishing one task becomes key. A web page with thirty options of things to do just becomes confusing and takes subtracts from the ease and enjoyment of using an app. The target metrics and engagement are very different in mobile when compared to just an online web page.

People are busy and often use applications with one hand. With web pages people are usually sitting in front of a computer with little to no distractions. From this point alone, it becomes easier to see how mobile development takes a whole new mentality in terms of user engagement.

It’s “Okay” to make an app for just IOS or Android

There was a time when mobile development was made for a specific platform. You could just create an app for the Google Playstore or the Apple store. Those days are over.

If your app does not exist on at least both Google and Apple your app ( and company ) is often seen an inferior and less professional. To add to the problem you are leaving market share on the table by not developing for as many devices as possible. On top of all that, if your app isn’t available on both stores you are basically inviting competition to “copy” your app and provide it where ever you are not! This just isn’t a smart move in most business peoples book.

Google and Apple development means learning two languages

There was a time where both Apple and Google development required you specific programming languages. Swift for Apple and IOS development. Kotlin / Java for Android development.

This has changed in recent years. Now there are languages and options to develop for BOTH platforms with one language. The one that I prefer (right now) is React Native. Other options are Google’s flutter, and langauges like Xamarin (owned by Microsoft)

These new options mean you do not have to learn two or more separate languages to have a mobile app available on multiple platforms. I recommend being in this space for mobile development. Word has it that many companies are also going this route. Why? This is because two or more separate teams are no longer needed.

Going to market for mobile apps is as easy as web

If you have ever done any web development. The release strategy can be relatively simple. Sometimes as simple as just uploading files to a server. For web development, this means you can release changes at any time an very easily, In come cases, releasing changes on a daily basis are common.

This is not the case with mobile development. Both Apple and Google have code reviews of you app BEFORE you are allowed to put it on their stores. No body wants an app on their phone that crashes as soon as you download it. We expect the apps we get from the Google and Apple Stores to work and that we can trust them with things like credit cards and personal information. So you can see why it makes sense that the app stores would insist on a general review of you app before it is placed in the stores.

** Depending how your app was created the review can be a few days to several days depending on what feedback you get from the stores.

If my app is beautiful it will beat my competition

I have run across this one several times in the past few years. Some people want to win a design award as recognition. Others want to show off a style of feature that they designed in an app store.

While I do agree good and beautiful design can make your app stand out from the crowd, that can never be at the sacrifice of the function of the app. If it’s pretty but crashes then it is useless on many levels.

Your reason for creating the app needs to be compelling in that of itself. The app has to provide some sort of value that other apps are not. BUT at the very base level it has to work without crashing and smoothly before making it prettier than your competitions app. If your idea is that your app will get customers because of your unique logo and not because it provides use to you clients / users you should save your time and money and keep you day job.

What does this mean to you?

Many of my readers are looking to become software developers (as perhaps you are in finding my blog). These few top of mind topics are meant to give you a primer on the mental shift that occurs when changing over from web development to mobile development. If you have never done web development, that is great! You have the advantage of NOT having some of the bad habits and pitfalls listed above.

All this being said mobile software development can be very rewarding. Seeing a customer run through your app without having to explain anything creates a great sense of accomplishment. If your new to the development game, I welcome you and encourage you to read more about development, and most of all. KEEP GOING!

Mobile Development, although challenging, is the best way to reach people and has replaced web applications in terms of market demand

Basic Programming 2 – Learn about functions

Reading Time: 3 minutes

Why are functions important?

Functions are how programs do work. Think of them as the action that is to be performed by code. Functions can return variables, perform calculations, or draw images on the screen. They are essential to creating applications in that they can define something to be done and to them over and over.

In fact, this is the proper use of a function. Imagine that you need to convert ounces to cups or inches to feet over and over. You could create an application that performs this conversion for you and use the program whenever you need to do the conversion.

How are functions created?

To get started (most languages) use the function key word. A keyword is a word that is pre-defined in a coding language that represents an action. In this case, the function keyword tells the chosen programming language that we are about to create a subroutine of code (an action that will be stored in memory as a variable)

Let’s take a look at a function and break it down.

function nameOfFunction() {
    let result = 1000
    return result
}

As we talked about earlier, we start with the function keyword. This keyword tells the language that the following code is a block of code that does something.

After the function keyword, we have the name of the function. I have chosen to call it nameOfFunction just to help describe what it does, but it would be any combination of characters we choose. For example, we could give the function a name of asdf123 instead. The program will not care what you name as long as it is within your chosen language’s guidelines for function names.

The next part we see that we should note are the parenthesis characters.

()

These parenthesis will not do anything for our basic example. However, calling attention to them is important as we will use them in a more advanced form of functions later. So take note of them, but don’t worry that they don’t seem to do anything right now.

The next part of our function to take note of are the curly brackets.

{}

These are very important. They define what is called a code block or block of code. Code blocks signify the start and end of a named space. You can think of this area as a separate universe or country. Within this code block whatever we put in it exists between those curly brackets ONLY. So in this example, as we keep moving forward with our function, you can see that we are using the let keyword to make a variable named result and assigning it a value of 1000.

Since result is inside of our curly brace code block it does not exit before or after the curly braces. This helps us make sure that we don’t accidentally assign it a different value in another function and ruin the nameOfFunction routine that we just wrote.

Side note: Don’t worry if this doesn’t make total sense right now. My intention is to start to introduce concepts that we can build on later. Not to introduce a concept like name spaces and have you understand everything about them right away.

The last part of the function that to cover is the line that reads

return result

The return word is also a keyword. This keyword allows messages to be sent outside of the universe we created between our curly brackets. This line tells the program to take the result variable and send it back to whoever (or whatever line of code) called it.

To use our new function, we would do something like the following code.

nameOfFunction()

This tells our program to look for something that we saved named nameOfFunction and do whatever that thing does.

So in our case:

  • Set a variable named result and give it a value of 1000
  • (on the next line) return the value of result

So in with our function, running it would return 1000. Alternatively we could have written the function as:

nameOfFunction() {
    return 100
}

This would have returned the exact same result as our original function, but would not have let us talk about as many concepts. So for teaching and example purposes being a little less efficient helps us learn more.

Next we will talk about more complex functions an the usage of the parenthesis as mentioned earlier.

Basic Programming 1 – Learn about variables

Reading Time: 2 minutes

Curious about programming?

Programming isn’t as difficult as it used to be. Languages have evolved to be more easily understood. This means good things for technology and advancement in general.  You don’t have to spend years learning a programming language. In fact, there are key concepts that are used in each language. You can concentrate on these main concepts to help get up to speed with any coding language that you want to learn. 

Setting a Variable

The first concept that you will need is the ability to set a variable. A variable is a way to assign something (a value or way of doing things) to a reference or place holder. This is a bit like calling something an automobile a Car rather than saying something like, “That large red thing over there with four wheels sitting by the curb”. By calling it a car we are creating something we both can use to refer to something (a reference).

This is an important concept in programming in that the things that we need to “remember” or “refer to” are often hard to describe. For example, a large number (3.14159265359) or a bit of code such as () => { return true }. ( try describing that to someone!)

 Example

Here is an example of how a variable is set in the JavaScript language (very popular these days).

cost footInInches = 12

Let’s break this down.

  • First is const this is short for constant (a value that will not change)
  • Second, footInInches is the name of the reference
  • Third is the = this assigns or equates the name with the thing to the right of the equal sign
  • Fourth, the assignment value or thing we are referring to

As a side note, the fourth part of the line of code (the value) doesn’t have to be a number. It could be a word, a equation, or even refer to another code file. This is the first concept that starts to open up the world of programming to endless possibilities.

Next concept we will talk about functions (article coming soon)

1 Hour of Code | A Great Idea

Reading Time: 3 minutesThe Hour of Code has come up as a topic of conversation a few times recently in my daily routines. The ‘Hour of Code’ is a nationwide idea (by Computer Science Education Week and Code.org) to introduce people to coding and programming. It’s a great concept and I suspect will be a great help as we keep moving forward in terms of the technologies of the future. It is essentially an event that will be held world wide to introduce people to the world of coding.

A Worthy Goal

The chief aim of an hour of code, it would seem to me, is to introduce new people to programming and prime new generations to idea of coding and creation outside of the normal physical creation patterns. Growing up it is common for children to be introduced to paint, pencils, paper, and other physical mediums of creation canvases. But, if you were born in a generation where programming and applications where not part of daily life, you might not even be able to introduce this path to the future generations. This is not your fault, but it would seem coding and programming is here to stay. The Hour of Code is a great concept to introduce the concept of programming to new generations where their older influencers might not be able to (experience wise or socio economically). This could give a needed introduction to a new minds that could transform or even push forward our advancements in technology. As with any skill or ability some take excel more than others in various areas. This might help expose a new mind to a place where they naturally excel.

Time Boxing – the difficulty of the task

As a programmer and thinking about the task of an our of code, this is no easy undertaking.  Each language has a base to learn. Even as I think about how to explain this the complexity makes my head to circles. I’ve been thinking about a good analogy for a  few minutes now. Here is the best description that I can think of… off the cuff. Teaching a new person about programming is like acquainting a person with new world. You need to find concepts that they are familiar with and relate them to the new world that you are trying to introduce. There are laws that can’t be broken. Not the kind of laws that come with punishment but laws that ensure that things actually work and don’t “fall apart”. One these are understood then you need to teach the person how to use concepts together cohesively so that they work in the way they are designed. If you are going to truly understand and be able to create in the programming head space you need to have the appropriate experience in hours and taking your lumps and stumbles.

I don’t think that the Hour of Code will be able to accomplish this in the time allotted. However, it should be able to guide very large groups of people through examples of how things are done. This would be much like taking a person on a guided tour of a forrest. You will be able to see the great sights and experience the space, but you should probably not be left along in the middle of the tour. This being said if you have the curiosity and the time, I would highly recommend trying to participate in the event. You might find a new area for your mind where you can excel where you never thought that you could, and although the Hour of Code is currently planned for certain days the intention is that it will live on (and hopefully help people keep learning)

Worried About Having the right Equipment?

If your interested in participating with your family (as this is mainly aimed towards children) check out the following map. I would also urge you to not just think of this as child’s play. If your interested in programming but have never taken the time or have not had the opportunity I would urge you to attend. You might be the mind that some company or innovation has been waiting for to help push towards the future!

3 DNA Repair Foods

3 DNA Repair Foods

Reading Time: 4 minutes

Research Into Ways to Prevent Cancer

I’m not sure if it’s the massive amount of new and information that is available now or actual number of occurrences. But, it seems like I am hearing more and more about friends (or friends of friends) that are dealing with cancer one way or another. Having a scientist background, I am very interested in this topic. Cancer is where the cells of your body misfire and keep grow (or replicate) without a stop signal.  ** Be advised this is a pretty rudimentary and blanket description

All the technical descriptions behind, it seems to me that the best that a human can hope for (save for adaptive evolution) is to function as designed. Meaning our organs perform at there optimal for their functions. The human body is constantly in a state of flux. Cells die off and are replaced with new ones sometimes on a weekly basis. The blueprint for the rebuilding of these cells is in our DNA.

Why DNA Repair is Important

According to research we have hundreds of incidents to DNA damage an hour. One article I read cites that as many as 800 incidents an hour. So if you estimate this out to a 24 hour day, this means close to 20,000 incidents a day. Yes, 20 thousand. So lets apply to this to our regular bodily functions. This means that at any given hour some of our cells are being damaged and repaired. This could be the any organ. Just pick any major one and you can see the problems that might happen. Now let’s factor in that if our DNA is repaired the wrong way (cancer) we could have major problems. Imagine if you have a house, and any part of your house is damaged 800 times in an hour. How many hands would you need to just keep your house up and running.

Luckily our bodies are adapted to do this repair and successfully do so for most people every day. However, how many of can honestly say we are “nice” to our own bodies? So this is where we develop a problem. What if the repair systems just plain can’t keep up and fall behind, or the number of incident rise to be too much for the repair systems? This is why healthy eating and being aware of carcinogens (cancer causing “things”) are important to know. As you body repairs itself it CAN make mistakes.

Take Care of Yourself

Given that our bodies can make mistakes in repairing itself. It is important to know that what you do in daily life can play a factor in how optimal you body performs. For example, it is well accepted that smoking whether it be cigars or cigarettes can increase the chance for a person to develop cancer. So if we accept that there are hundreds of DNA damage incidents an hour, and that smoking increases the chance for cancer. I would, and do, chose to not smoke. Originally it was not for these reasons, however this does re-enforce my decision. There are also less popular areas to moderate that could effect your chances.

Imagine being on a beach, with your favorite cool beverage in hand, just relaxing and enjoying the scene for hours and hours. It’s one of my favorite images for relaxing and recuperating from stressful work situations for sure. But, as many of us know, the sun itself (UV rays) can cause DNA damage. So apply your new knowledge about DNA damage by the hour. It’s actually more risky than most people suppose. I’m not saying you should never be in the sun. Although I do know people how consciously decide to walk in the shade, I don’t think this is totally necessary. However, if you read most any articles and research on skin cancer, it is recommended to avoid the peak hours of the sun. This means staying out of the sun from 10am – 4pm when the sun is at it’s most powerful.

Sound horrible? It is hour right to choose how you life you life. I just think it’s important to be in-the-know and have a choice than to stumble upon something that may have been avoidable. I personally wear sunblock whenever I can and make sure I am wearing it when I am in direct sun. My adoption of this information just means I plan my hikes so that I’m done before 11am or noon at the latest. If I’m invited to hours and hours on the beach I will be SURE to wear sunscreen and probably bring some sort of cover / shade to sit under.

Give Your Body Good Things to Build With

The last part that I’ve adopted is based on research is diet. This is the hardest part for me because I am a food lover! It’s hard to refute the saying  “you are what you eat” given that what we eat is used to fuel and rebuild our bodies. It is important to be conscious of  what you feed your body. There is a lot of ongoing research about food. In fact, too much to even scratch the surface in this article. There is ongoing research on organic vs organic foods, food genetics, soil compositions, oceanic and air pollution, the way we prepare our foods etc. All of them worth reading if your trying to educate yourself on these matters.

One surprising bit of research that I ran across is that fruits can have an anti-cancer effect in the body. I’ve seen articles including strawberries, blueberries, and even kiwi fruit. Other that show that cruciferous vegetables have a preventative DNA damage effect as well as possibly an ability to inactivate carcinogens. Other interesting research proposing that tea drinks can also help with anticancer activities. Green teas specifically contains polyphenols that are thought to contribute to anticancer activities.

Take Action

Based on my research, here is the advice that I have adopted.

  1. Eat berries
  2. Eat cruciferous vegetables
  3. Drinking tea and other antioxidant good and drinks
  4. Exercise

I’d recommend continuing your own research and deciding which (if any changes) are appropriate for you.

Coding vs Programming

Reading Time: 3 minutes

If you have ever thought about building and application, or have spoken to anyone that has, you have probably use the words coding and programming. These words are often used interchangeably and often are confused into seeming like they mean the exact same thing. These two words actually have different contextual meaning in the realm of software development.

What is the difference?

To understand the differences it’s worth talking about the thinking that happens when looking to build a useful application. Technology, in general, is created to help solve problems and even further usually for a very specific problem. These problems can be a business, social, physical, or just solving the problem of everyday boredom. At the core of building an application is the problem that the software is seeking to help or fix outright.

In corporations / companies there are groups of people with the sole purpose of defining the problem and proposing solutions to that problem. These employees are titled business analysts, the are totally separate from the programmers that put fingers to keyboards and write the actual code. These employees help define the actions and behavior that is needed for the software. These can be things like does the application require a login, does it require payment through credit cars, and are there any analytics or reports that are needed once the program is up and running.

After the business analyst has gathered enough of the particulars (called requirements) the ideas can then be discussed with a programming team (or lead programmer). Here the team will look at the requirement and determine the IF the functionality can be created and what has been asked for can be done within the proposed deadline. These negotiations can weeks depending on the complexity of the problem and the programming language that has been chosen

Programming

Here is where the differences between programming and coding begin to make themselves more clear. After the problem is well defined and it has been determined that the program can be feasibly created it comes time to actually plan how the data flows and the program methodologies that will be used. This is where the programming CAN begin. When a season programmer is giving a problem to be solved they have the acumen and experience to see the needed functions and behaviors to appropriately employ patterns and tools to get the job done. This means they can and have been empowered to make these types of decisions. Programming is more than just typing or putting thoughts to paper. It is implementing known patterns and algorithms that other developers can understand such that the solutions can be expanded upon and maintained later.

Coding

The other way that the program can get written is to contract out the actual fingers to keyboard out to contract company or possibly outsource the work (sometimes in another country). This requires that the corporation (often the lead programmer) take the time to plan and detail all the parts of the program that need to be created. This means down to the detail of something like this bit of code should accept only money values and return a value +/- an expected result of so many dollars. Another example would be written in a specific language and the result that comes out be in an agreed upon format that is well known throughout the industry. These types of specifications should be easily measured and easily determined if they task has been completed or not. For example, this program accepts a date from an emulated calendar. This date can only be accepted if it is in the future (not today or yesterday) in the forma mm/dd/yyyy and not more than 30 days ahead of tomorrow. Executing on these types of requirement is referred to as coding. There ideally no guesswork and it can be broken down into very small tasks. This is the coding aspect of a project. This requires less creativity in description but much more specificity in what is wanted and can be accepted.

A decision based on your needs

Both programming and coding require high amounts of skill, creativity and critical thinking. However, the programming type is trusted with much more autonomy and creativity. The coding style is less interpretive but you typically know exactly what you are getting (if the requirements are met). Programming is great if you already have a team that you trust and know they can fulfill your needs. My advise in deciding what type you should hire would be if you already have the resources hire developers that can handle making good programming decisions about scalability and future use. If you are on a limited budged and don’t have a team. You can leverage a the coding style coder to get your application done. However, without a team of programmers you will need to clearly defined everything that is needed BEFORE the project begins. If you start this process after you being your costs will be much higher that you could ever expect.
