Value & Time

Growth

When we think about value, we think about the cost we pay for something. However, that’s a very shortsighted definition. We probably only consider cost as defining value because most of the things we buy are defined this way. For instance, when we go to a grocery store, we look at two brands of cheese, and the cheaper one is the better value. It doesn’t matter much which is the better quality cheese, it simply matters which is the cheaper cheese. As consumers, we typically only consider the cost. To me, the definition of value is far more complicated.

Buying Vacuum Cleaners

Twenty years ago, when I would buy a vacuum cleaner, I only considered cost when purchasing. The cheapest vacuum was the best value and the one I would purchase. But time and time again, I found that my value vacuum cleaner would stop working after about a year. So, I’d go back to the store and buy another one. I was paying about $100 per year to purchase vacuum cleaners. Note that now my value definition has a time element. After several years, I considered buying a Dyson vacuum cleaner. It was four times as expensive, but I had hoped it would do a better job than the $100 vacuum cleaners and that it would last longer. And today, 15 years later, I still have that same Dyson vacuum cleaner. If it were to break today, I would have spent $400 over 15 years for my vacuum. That’s a substantially better value than before!

Value of Technology

The cost of computer technology is very similar. You can buy the $300 laptop and expect to replace it next year, or you can buy a MacBook and have it for 10 years. But custom software is a little more difficult to directly compare since the price tag isn’t as clearly defined. What I’ve found is that when customers purchase consulting services or software development services based solely on the cost of those services, they often find that the price tag explodes over the lifespan of the product due to poor development. When you find the developer with the lowest cost, he probably has the least experience. He will take longer to accomplish the work since he’s bound to run into more snags than an experienced developer. He’s also likely to overlook things that a senior developer wouldn’t. These issues will result in additional costs during the lifetime of the application to fix in addition to lost time and productivity from your software users.

Conclusion

Paying for custom technology services is more like buying a vacuum than it is purchasing a block of cheese from the grocery store. The true value of those technology services will be defined not by cost alone, but by how long those services solve your technology problems.

Drive & Success

Drive

Most people would say that I’m a successful person. I’ve started my own business, enjoyed 20+ years of a happy marriage, raised a wonderful daughter, earned a third degree black belt, and done so much more. Of course, each of us may view success differently. To some, success may be earning their first million before 30 or to earn their MBA. Success may be marrying the woman of your dreams or buying the car you’ve always wanted. Regardless of how you define success, the formula is pretty much the same.

Drive

The relationship between drive and success is well defined. Tommy Hilfiger said: “The road to success is not easy to navigate, but with hard work, drive and passion, it’s possible to achieve the American dream.” Chuck Norris also recognized the connection: “I’ve always found that anything worth achieving will always have obstacles in the way and you’ve got to have that drive and determination to overcome those obstacles on route to whatever it is that you want to accomplish.”

But what too many people seem to ignore, is that the opposite is also true – without drive, you will have a very difficult time being successful. When I look around, the people I most often see struggling to get by are the same people who have little – if any – drive. They buy their next lottery ticket and hope this is the one. They put their money into fad diets because it’s easier than working on the body they want. They rely on whatever easy method or get rich quick scheme they can find. And where does it leave them? Exactly where they started.

My wife has often says I’m driven by a rubber band. She says that I never stop, and that she believes I could achieve anything if I set my mind to it. I’m thankful to have that drive. It has served me well. But to those of you who have not achieved the success in your life you have wanted, why do you think that is? Are you driven to success, or just driven to the couch to binge watch the next season of your favorite show? Are you as interested in learning Italian as you are sitting on the deck all summer? If you’re not getting where you want in life, what do you intend to do about it?

It’s never too late to change your life to be what you want it to be. However, you need to start by taking charge of your life and focusing on the things that will drive you toward the success you wish to achieve!

Samsung Galaxy Watch

Galaxy Watch

Over the last several years, I have owned several smart watches. Unfortunately, I was never impressed with any of them. Early smart watches had horrible battery life. At the end of the day, it was not uncommon for my watch to have less than 20% battery  remaining. Use your watch more heavily, and you could expect to recharge mid way through the day. While early smart watches were nice toys, they lacked any real use case beyond being able to read your text messages.

How things have changed. I bought a Samsung Galaxy Watch hoping to give smart watches another try. Not only is the battery life amazing, but so are the features. At the end of the day, I typically have 70% or more battery remaining. I can now go multiple days without charging! In addition to being able to send and receive text messages, I can use my watch to make calls! The Samsung Galaxy Watch includes WiFi, NFC, optional 4G, and is even waterproof!

The Samsung Galaxy Watch is also an amazing tool for runners, hikers, bikers, and anyone who wants to keep track of their exercise or heart rate. With GPS, altimeter, barometer, step counter, and heart rate monitor, the Samsung Galaxy Watch is the perfect tool for any fitness enthusiast.

The Samsung Galaxy Watch has rewritten the book on smart watch technology. Their watch is absolutely amazing and is the first smart watch I have ever really loved.

Remote Connections

Computer on a Tree Stump

As a techie, I often need to connect to a variety of computers to accomplish my work. But as a small business owner, I enjoy the freedom to do my work from wherever I choose. How can you accomplish both? Remote connections! Through a variety of technologies, I am able to access the resources necessary to do my job from anywhere around the globe.

SSH

The simplest means to remotely connect to a computer is through Secure Shell – better known as SSH. SSH is a secure replacement for the much older (and insecure) telnet protocol. SSH uses public-key cryptography, so you can setup keys to connect to your server instead of a password. This makes connecting easier and more secure. SSH is a text-only connection type and is particularly well-suited for Linux machines. However, while SSH is a great tool for controlling a Linux server remotely, it doesn’t allow you to use resources on that server (or network) from your local machine. For example, if the remote server runs a website, you won’t be able to access that site via SSH.

SSH Tunnel

While SSH won’t allow you to access remote resources directly, you can turn options for tunneling. Tunneling will map local ports to remote ports so that your local computer can access resources on a remote computer. For example, if your remote server runs a MySQL server, you can setup an SSH tunnel to forward localhost:3306 to remotehost:3306. Then, you can setup your MySQL client to connect via your local machine. The SSH tunnel will then forward your requests to the local machine. I heavily use this technology for web sites on my development build server. For example, I run a Jenkins server on port 8080. I can SSH into my machine and create a tunnel to port 8080. This allows me to view my Jenkins web server from anywhere. I even have an Android application (JuiceSSH) that allows me to setup SSH tunneling from my phone. So, when I need to control a Jenkins build on the road, I connect via JuiceSSH and make the necessary changes.

VPN

Sometimes, a tunnel just isn’t enough. Maybe you need your computer appear to be on another network. Running my own business, I have some clients who allow me to access their systems – but they require me to connect from my office IP address. Since I like to travel – or work from home – I need a way to remotely connect to my network. A VPN is the perfect solution. I can access everything on my network, and I appear to be on that network by other systems. Unfortunately, a VPN is a little more complicated to setup. OpenVPN software is available to setup a server, but I have found it more difficult to setup than I would like. (When I did get it setup, I found it frequently locked up on my Linux server too.) So, I decided to buy a Netgear Nighthawk router. Their embedded VPN works great from Android, Mac, iOS, and Windows.

An added bonus of a VPN is that it can be used to secure your connection when you are using a public WiFi connection. Additionally, since you will appear to be at a particular IP address, you can access services that are only available from your geographical area. For example, web-based TV programs only available to users within a specific geographical area.

Conclusion

The ability to remotely access resources means you can work from any location in the world. You don’t need to be at your office. You can even access your home computer from work or from your phone. If you’re looking for an easy way to connect, look at SSH – it’s a simple and very effective way to access remote computers!

Development Environments

Workbench

As a developer, it’s a great time to be alive. We have countless options for development languages and frameworks. But, sadly, many of them leave much to be desired in terms of tools and environments.

The Model Environment

As a veteran Java developer, I’ve been spoiled with excellent tools. We have numerous IDEs including Eclipse, NetBeans, and IntelliJ. Everyone has their preference, but all three are excellent. Likewise, we have numerous build and dependency management packages such as Maven and Gradle. We have test frameworks, automation frameworks, debuggers, profilers, and anything else you could want to engineer even the most complex of application. In short, Java provides the best development environment there is. Seriously. Few languages have IDEs as good as what Java has. Even fewer have tools that can complete with Maven or Gradle.

When Will Other Languages Catch Up?

I continue to see how Python is displacing other languages. But when will it catch up to Java in terms of development environment? Are there any IDEs that complete with Eclipse for Python? (NOTE: Eclipse can actually be used for Python, but it always seemed to me more of a hack than a real Python IDE) How about debuggers? Go ahead and try debugging Python or JavaScript code and you’ll quickly see how far behind Java they are. Not to mention dealing with libraries and environments!

A Call to Action

As we continue to shift to newer languages, I’m concerned that the next generation of developers will actually have a more difficult time than we do today. Why, as a development community, are we only focused on creating new languages but not on creating solid environments? How are Go, Python, Rust, and the myriad of other languages ever supposed to achieve the same widespread adoption of Java if we never had the rest of the tools we need to get the job done? I want to enjoy the benefits of some of the newer languages to come along. But, until they can complete with Java, I’m unable to stake the success of my customers on them.

Fit for Sale

Sales

As an app developer, I am often approached by friends and acquaintances with “great” app ideas. They believe their idea is worth millions and that I should drop everything and develop their app. Businesses too fall prey to the idea that “I need an app“. Either way, it’s imperative that adequate market research be performed prior to developing any piece of software. 

A Great Idea

A few years ago, I was approached by an individual who had a “great idea” for a software application that was going to revolutionize the industry. He had some startup money to develop the application, and was in a hurry to get started. He contacted me to write him a mobile application, cloud-based management system, and REST services for integration points. It was an ambitious project for the client, and I was excited to start developing. He provided the requirements to me, and I wrote the software. I provided feedback to improve the application, but it was ultimately the customer’s decision what he wanted to include or not include.

Poor Market Research

Unfortunately, as the project moved forward, I learned that the client had very little money for development. None-the-less, we worked to create a working product which we achieved on his budget. But, as he would learn during the next month, he was creating an application that nobody actually wanted. Not only did his application lack features that would be necessary for adoption, it served only a very small niche market. The customer assumed he knew what people wanted, and had never bothered to reach out to any prospective clients for feedback.

Consequences

Due to the customer’s poor market research, he was unable to find clients interested in his software application. Months went by with very few interested parties, and nobody ultimately purchased the software service. Consequently, the customer blamed me for writing an application that nobody wanted. He even fought me on payment because he was unable to make his money back through sales.

Lessons Learned

There are several important lessons to be learned from this experience. First, if you’re paying someone to write you software or create any other work for you, make sure it’s worth the cost. It’s your job as the customer to know what you are purchasing and to ensure that it will meet your business objectives. As a software consulting firm, I can provide you with information and develop software. However, I can’t tell you wether or not your application will be a success. Second, market research is of paramount importance for any project. If you don’t know the target market, the demographics, the estimated number of consumers, and other key data; you can’t determine financial viability of the project. Before you go into any project, do your part first and ensure that the work you are paying for will take you where you’re trying to go!

Debugging & Maintenance

Debugging

Long after the initial fun of developing an application comes years of debugging and maintenance. Yet, many languages and developers fail to make choices that will ensure that future maintenance will be possible. Then, when problems occur, substantial time and effort is spent trying to resolve the issue.

Current Trends

It seems that right now, a growing number of developers and development teams are transitioning to languages like Python and Javascript. Both of these languages can do great things. Unfortunately, they both suffer from the same problem – they are incredibly hard to debug and maintain. Why is that? Python and Javascript are both weakly typed scripting languages. What does that mean? In short, it means that the programmer can be lazy about how they define things and let the computer do all the work. Unfortunately, it also means an increased risk of runtime errors and greater difficulty in finding problems.

Magic Frameworks

This is exacerbated by magic frameworks. Everyone loves Ruby on Rails and Django. But both become a nightmare to debug very quickly. Need to change something from the framework? Great – your hack will be the source of nightmares when you leave. While these frameworks may simplify our lives in the short term by providing a quicker time-to-market, in the long-term they are more difficult to maintain.

How Can We Fix This?

Unfortunately, I have rarely seen well documented Python or JavaScript code. Typically, users write code and forget about it. Online videos and tutorials rarely stress the importance of comments and documentation. Thus, we end up with fragile code nobody understands. As a developer community, we need to do a better job of passing on our knowledge of code to the next developer. This means comments, readme files, and other documentation. If you write software using weakly-typed scripting languages, you owe it to those who will debug your code later to put in the extra effort!

Classic Hacking

Security

I’ve been involved with technology since the mid 90’s. During the late 90’s, I worked on Unix systems. It was those experiences that lead me to love Linux, taught me to program in C, and helped me learn to automate tasks using various scripting languages. But the 90’s were a much different time for security. Nobody really worried much about hackers or social engineering. And now, over 20 years later, I see people in the workforce that have been robbed of some of the fun I had in the past due to increased security on machines. Of course, increased security is good, I’m not going to argue otherwise. But it has also made a lot of the ‘fun’ from the past no longer possible.

Remote Display

When I was working on old Unix systems, one of my favorite hacks was to set my display to another computer. Since Unix display works as a client/server model, you can actually set your app to appear on any computer monitor you want. So, it was common where I worked to find the most horrible graphic you could and display it on someone else’s machine. Always a good laugh. Other tricks would allow you to play audio on their speakers (great when the individual has fallen asleep at their desk) or turn their keyboard buttons on and off.

Password Files

Long before the /etc/shadow file, passwords were stored in the /etc/password file. And, since the file was readable by anyone, you could easily grab the entire password list and run it through a tool like John the Ripper. Even more fun, commands like ‘ypcat’ would allow you to get the passwords of all users on the network even if they weren’t on the local machine.

Email Overflow

My sister’s first experience with the internet was through a device called “WebTV”. This device was a small terminal that would turn your TV into an internet terminal. It was a cheap, easy alternative to a computer. It also suffered from a pretty simple flaw – you could only have a limited number of emails. (200, I believe.) I found an unsecured email relay – pretty common in the 90’s – and spammed my sister with enough messages to flush out all her email. As you might guess, she was mad.

A New World

How things have changed. Unsecured email servers are much more difficult to find, and Unix is now much harder to hack out-of-the-box. While most of the hacks of twenty years ago were mischievous in nature, today’s hackers are far more sinister. And, thankfully, the world has adapted to become a safer place. Nonetheless, I still look back to the simpler days of computing and the fun we had.

Scheduling & Planning

Schedule

Last January, I made a decision that profoundly changed my life – I started scheduling and planning my time. Most people are subjected to schedules and plans at the workplace, but few take their life so seriously. As a consequence, we all end up in a place we never intended to be. We all have hopes and dreams, but we fail to plan the steps necessary to get there. During the last year, I started my business full time, completed 61 college credits in 6 months, read four books in Chinese, and accomplished more than I have in years. None of these things would have happened without planning and scheduling.

Pen & Paper

Many people may use electronic tools like Google Calendar or their iPad Reminders. While these are both great tools, they are way too easy to ignore. I have found that using a written planner is so much more effective. Every night, I plan out out the most important things I need to accomplish the following day. On Sunday, I plan the big items I need to accomplish throughout the week. I take notes of what happened in any given day so that I can reflect on my progress later and see where I can improve. I nearly always have my journal nearby so that I can capture anything important to me.

Electronic Tools

While I prefer to do my scheduling and task lists on paper, there are some things that simply work better via electronic scheduling. For instance, when I write a blog post, I schedule it to be published at a future date. That way, I can write several posts during one block of time and have them go out during the upcoming month. For my social media, I use HootSuite for the same purpose. I can schedule all my media for the week or the month and not worry about it during the week. This ensures that my blog and my social media are constantly fresh and updated without the necessary worry about posting every day.

The End Result

Through the use of scheduling tools, I have found that I am able to be substantially more productive than ever before. Tasks get accomplished on time, more gets done, and I have more free time to focus on the things I enjoy in life. Even more importantly, I know where my life is headed. I have a plan, and I know where I’m going. Do you?

Payment Terms

Money

Recently, a fellow small business owner asked me how I handle billing. For a small business, money is often one of the biggest concerns. Without a steady flow of cash, you can’t meet your business objectives or your personal financial requirements. As a small business, you have to determine when to bill and how to bill. Even worse, you have to define how you deal with delinquent payments – which can kill your business.

When To Start Billing?

The first question to answer is when do you start billing? This is particularly true if you’re billing by the hour. Does the clock start ticking at your first meeting? After the project requirements are defined? After the project is complete? For my business, anything after the initial project meeting is billed to the customer. I think it’s important for a customer to understand that project planning, requirements gathering, and any other tasks completed before any actual code is developed is an integral part of the development lifecycle. I typically bill the first of the month after any billable hours have accrued. I’ve found that the longer you wait, the more the bill increases. Then, you risk the customer suffering from sticker shock when you finally send the bill after months of work.

Late Payments?

When I started my business, I was so pleased to have customers that I didn’t worry about late payments. I assumed that my customers respected me enough to pay me on time. I was incredibly wrong. What I’ve found instead is that many companies will put me at the bottom of the list of payees. Why is that? Well, I think it’s pretty simple. The customer knows they have to pay their lease on time or risk eviction. They know when they fail to pay their internet bill, they won’t be able to perform their mission. What happens when they don’t pay you? Likely nothing. Additionally, they know you don’t have a collections branch and are unlikely to use a collections agent. Thus, they have absolutely no reason to worry about when they pay you. I have learned to include verbiage in my contracts defining payment terms. I give customers a 5 day grace period, and after that the customer is charged a late fee. Additionally, all the customer’s projects are paused until payment is received. If you continue to work, you end up months behind on payment and continuing to work for free.

What About Equity?

I’ve had many ‘customers’ offer to pay me in equity. I do the work and they will give me a percentage of the revenue generated by the software. I have a very simple answer for this kind of relationship. No. While an individual may think that their idea will generate millions, they rarely do. Even worse, you’ve now wasted time developing software that you will never be paid for. The original ‘customer’ lost nothing. You lost countless billable hours to a project that will never be profitable.

Conclusion

Money is the lifeblood of any business. What I’ve learned is that it’s imperative to have clearly defined payment terms and procedures for your business. When you fail to make those terms clear to customers, you will quickly find that your business struggles to get by and that you are spending more time nagging customers to pay than you do performing your business’s objectives.
