What You Need To Know About Apps

Apps

As companies prepare to enter the new year, some will embrace new technologies like mobile applications. While a large number of businesses already have apps for both Android and iOS, may smaller business do not. Those businesses will have to decide if the investment will provide value for their users as well as their organization. To help make that decision, it’s useful to better understand the mobile app ecosphere.

Android or iOS?

The most important question is what devices you are targeting with a mobile application. Are you only looking to support iPhones, or do you want Android too? This decision will drive the rest of the decisions you make. While most organizations want an application for both platforms, you may be looking to create apps for a niche market better serviced by one or the other. For example, if you want to create an app that will target a handheld barcode scanner and label printer, you’ll want to develop for Android only as iOS doesn’t support that that hardware.

Native or Hybrid?

The next question is if you want the app to be developed natively or using hybrid technologies. The difference is the programming environments used as well as the development time and costs. While native apps almost always ‘feel’ better than their hybrid counterparts, they also require developing separately for both platforms – which increases the development time as well as the cost. Conversely, hybrid apps can be written once and will work well on both devices.

Costs & Monitization

To place an app on either store, you will need a license. For Google, this is a nominal one-time purchase, but requires an annual license from Apple. If your organization is a non-profit or business that doesn’t wish to pay an annual license fee, you may wish to skip on Apple development. If you’re planning to sell your app on the store, note that both Apple and Google take a 30% cut of all sales. This can be significant cost, but the large market available to you makes it well worth the cost.

Approval

After you’ve created your app, it will need to be reviewed. Both Google and Apple have staff who download apps to verify compliance with their rules. Note, it is possible for your app to be rejected, in which case you will have to make modifications and resubmit.

User Acceptance

One last point I’ve learned is to make sure your app services a purpose. I’ve had several clients create an app they thought was great only to find that nobody downloaded or used the app. This can be disappointing and lead to a substantial loss to the business. The best way to avoid this is to ensure that you’re creating an application that fills an actual user need – not just something that you perceive as a need.

Conclusion

The decision to make an app can be a big one with lots of options and potential costs. Take time to research the market and ecosphere before you jump in and you will have a much more successful app launch!

Cool Tech Gifts for Christmas

Circuit Board

With Thanksgiving behind us, it’s time to start looking for gifts for the important people in our lives. If one of those people happens to be a techie, what can you get them? Particularly if they’re a teen? Here are some ideas of cool tech toys for the people on your list.

Electronics

There are some really great products out there for learning more about electronics. One of my favorites is littleBits. Each piece contains a separate electronic component – such as a speaker, button, or power cell – than can be connected magnetically to create circuits. With a variety of sets available, you can create all kinds of projects.

Another cool electronic toy is Snap Circuits. Snap Circuits are more like a traditional electronics learning set, but instead of using wires connected to metal springs, the pieces are snapped on a board with metal buttons. These buttons connect pieces together to create the electrical circuitry.

Both of these sets are appropriate for children as young as elementary school and are great for learning the basics of electrical engineering with countless online and print books available for project ideas.

Microcontrollers

For the techie with a bit more experience in electronics, a microcontroller may be the perfect gift. Today, there are countless microcontrollers available. However my two favorites are the Arduino and the micro:bit.

The micro:bit was developed by the BBC to teach children more about electronics and programming. It’s a small device, but it packs a lot of cool features including a grid of LEDs, an accelerometer, buttons, and built-in bluetooth support. They’re very easy to program and fairly inexpensive. NOTE: buy two, you’ll need them to play with the bluetooth functionality!

For more mature electronics enthusiasts, the Arduino is amazing. In fact, it is well beyond a toy for learning and has transcended into the hands of professionals creating prototypes and products. Countless kits exist on sites such as Amazon that include wires, motors, LEDs, buttons, resistors, and countless other components to build just about anything. In addition, since Arduino is truly the industry leader, it’s easy to find books and online resources for help as well as inspiration.

Microcomputers

With more power than microcontrollers and more versatility as well, microcomputers offer unlimited opportunities to create and explore. The industry leader in this real has long been the Raspberry Pi. About the size of a credit card and costing substantially less than a typical computer, the Raspberry Pi is an excellent platform for learning and exploration. You can interface the Pi with custom hardware, learn to program with Scratch, create a custom video game console, or explore countless other options. And, much like the Arduino, online retailers have numerous kits with all kinds of parts to aid in learning and fun.

A newcomer to the microcomputer realm, the NVIDIA Jetson Nano offers programmers and techies a new real to explore – artificial intelligence! This small box (about the size of a Raspberry Pi) features an NVIDIA graphics processor specifically configured to perform the intense number crunching associated with AI processing. This is an excellent gift idea for those who already have some background in programming and electronics and want to take their ideas to the next level!

Conclusion

This is a great time to be a techie. With countless low-cost gadgets available to encourage exploration and experimentation, the barrier to learning technology has never been lower! Take time to explore the products out there and buy something that may encourage someone in your life to join the tech revolution!

Simple Tips to Avoid Scammers

Gangster

It seems that every day criminals find new ways to separate victims from their money. However, most of these tricks can be avoid with three simple rules.

Assume all email is junk mail until proven otherwise

Email is the easiest way to scam people. It takes little effort to send out thousands of messages, and scammers win if even a small percentage of people act on their messages.

Don’t click on links. If you believe the email to be from a reputable source, go directly to their website instead of using the email link

Don’t open attachments. This is particularly true for unsolicited Microsoft Office documents such as Word and Excel, but equally important for any other attachment. If you believe the attachment to be valid, contact the sender by phone and confirm they sent it.

Contact the sender directly. If you get a message claiming to be from someone important in your organization and asking you to do something that seems odd, contact the person and verify authenticity.

Assume all phone calls are spam

Suspect local numbers. If a caller claims to be from your credit card company or the IRS, but their phone number is from your area, it’s a scam.

Ignore callers from India. Does the speaker have an Indian accent? It’s a scam. The overwhelming majority of spam calls originate from call centers in India.

Caller can’t provide you with information. Does the caller know your name, address, account number, or other information? If not, are they really your bank? I doubt it.

Avoid entering data in unencrypted sites

Check for the secure icon in your browser. If the web site you’re visiting isn’t encrypted, be skeptical. Particularly if they’re asking you to enter personal information. Never, under any circumstances, enter your credit card information in a non-secure site.

Conclusion

The simple answer for security in the modern age can be summed up “trust no one”. Assume everyone is out to scam you, and you’re probably not far from the truth. If you want to conduct business with an entity, go to their web page directly or contact them on the phone. Always assume the incoming solicitations you receive are from people trying to cheat you and you will likely avoid most scammers.

Skills All Developers Should Know

Tools

When I talk with developers, it’s amazing how many of them are disappointed with the limited job opportunities available to them. Often, the problem is that they lack many of the common skills required to be an effective programmer in today’s market. These developers have managed to become specialists in a very specific technology stack which isn’t widely used elsewhere. I’ll tell them some things they should learn, and – surprisingly – they’ll often argue that the specific skill I mentioned isn’t that useful. What are those skills?

HTML

First and foremost, every developer today needs to know HTML. In our web-based world, it’s hard to find work that doesn’t require HTML at some point. This is obviously true for web development, but is equally valuable with hybrid mobile technologies such as Cordova or Ionic. Or, maybe you need to create documentation for you application that will be accessed on the web.

JavaScript

While every developer may use a different programming language for backend development, we all use JavaScript for web programming. But JavaScript goes well beyond that. Today, JavaScript can be used for developing backend services with Node or even interfacing with Arduino hardware with the Johnny5 library.

Git

Developers need to be comfortable with Git from the command line. GUIs are nice, but when you need to automate a build script or download code from a command prompt on a remote computer, the Git command line is essential.

BASH

Like it or not, much of the cloud runs on Linux servers. As such, a knowledge of BASH is essential in today’s world. While many developers prefer a Windows only world, it’s just not the case when you have to deal with Google or AWS cloud services.

SQL

It’s amazing to me how many junior developers are unfamiliar with SQL. In today’s marketplace, nearly every application needs to interact with a database somewhere. Whether it’s an enterprise application using Oracle or an Android app using SQLite, SQL is the common way to interact with a database.

Conclusion

It may be noted that – other than JavaScript – no programming languages are on the list. Whether you develop in C, C++, Java, Swift or some other language, the above skills will apply. There are countless toolkits and frameworks, languages and environments. However, nearly all of them will require some mix of knowledge of HTML, JavaScript, Git, Bash, and SQL

Attitude Matters

Bad Attitude

Anybody who has ever looked at job requirements for technical staff has probably noticed the huge number of skills required. This may include programming languages, hardware platforms, frameworks, protocols, or countless other technical specifications. However, what you will see far less often is interpersonal skills or attitude. In reality, these soft skills are typically far more valuable.

This week, I overheard an aspiring programmer discuss how he found it “mentally draining pretending to care about business needs our values”. I immediately jumped in to try to correct his errant thinking. As the discussion continued, he made it abundantly clear that he only cared about money. In fact, the only reason he was going to school for technology was to make money.

While many people chose their profession based on financial factors, money should never be the primary motivation. Why? Because study after study has found that money is a poor motivator of behavior. Instead, people motivated by the intrinsic characteristics of a job are far more successful. For example, as a programmer, I’m motivated by helping business transform their operations through technology and by the challenge of the problem. While a large number of the applications are, in themself, boring; solving complex problems and helping businesses grow is always exciting.

For the individual trying to find a job, learn to be motivated by the job instead of the money. Not only will it help you perform better, it will help you develop a more positive attitude.

In the end, most business owners would rather have a less technically competent individual with a positive attitude than a more skilled individual with a poor attitude. For the business, they can train the desired skills, but fixing a poor attitude is far more difficult.

Backups Are Not Optional

Drives

Recently, I visited a customer site for what seemed like a simple request – to update their Windows computer. However, in the end, the machine had to be reformatted. The customer was very worried that they would lose critical data on their system. That didn’t happen, but I was concerned that the customer wasn’t performing backups on what he considered to be critical operational data.

Today, failure to backup important data is not excusable. With the advent of cloud services as well as cheap data storage, customers have countless options for ensuring their data is always available. Regardless of the operating system or situation, everyone should be performing regular backups of critical information.

Backup Options

For Mac users, Apple’s Time Machine is the way to go. The gold standard for computer backups, Time Machine automatically backups up your entire system whenever a configured hard drive is connected to the computer. Not only is it easy to configure and implement, backups couldn’t be easier. During setup of a new Mac computer, simply plug in the Time Machine drive and the OS will take care of moving everything to a new system. It could not possibly be easier. Additionally, Apple’s iCloud drive is an incredibly cheap cloud-based backup option. The free iCloud storage allows up to 5 gigs while paid solutions start at only .99 cents per month.

Unfortunately, Windows users don’t have anything as nice as Time Machine. However, Microsoft’s OneDrive allows free storage of 5 gigs (like iCloud) and up to 1 TB for only $6.99 per month. With automatic syncing to the cloud, OneDrive can quickly – and easily – protect mission critical data.

In addition to the above, countless other options exist. Google Drive, a service similar to OneDrive or iCloud, allows 15 gigs of free storage. For developers, both BitBucket and GitHub provide off-site storage of source code. For your cell phone, Google Photos can backup every selfie you take so you never have to worry about losing the pictures on your phone.

Conclusion

In the end, it doesn’t really matter what service you use or how you do your backups. What matters is that you’re doing them. For me, as a business owner, the loss of my business data would be catastrophic. So, I have implemented various backups to preserve critical files. If my computer blows up today, I’ve got nothing to fear – I’ll be back up and running tomorrow.

If you are concerned about what would happen to your business in the event of a computer crash or catastrophic event, contact someone in your IT department. If you don’t have an IT department feel free to contact Talixa Software for assistance.

Tech Tip: Google Alerts

Alert

Google is responsible for innumerable software tools and applications. Chrome, Android, the Pixel, GoogleFi, and Gmail are just a few. But there’s a particularly useful tool that few people seem to know much about – Google Alerts.

Google Alerts is a service where Google will email you with new results for a desired search string. This has a few particularly useful applications for business and security.

First, entering your name as well as any common variations (Tom vs Thomas) can be useful for identity monitoring. Every time something comes up with your name, you’ll be notified. Quoted in the paper? Named in a lawsuit? Listed as next of kin in an obituary? If your name is associated with new content, you’ll be notified.

Second, entering your company name is great way to keep track of anybody mentioning your business. Even better, enter the names of your competitors so that you can keep track of any news releases associated with them as well! Of course, you can also use Google Alerts to get new information on your favorite musician, actor, or any other subject of interest to you.

While not as exciting (or as well known) as many of Google’s products, Google Alerts is an excellent tool to keep track of your digital footprint, keep up to date on your competitors, or stay abreast of the things that matter most to you.

Remote Work? It’s Not All Good.

During the last few months, we’ve seen a huge shift by companies to encourage remote work. Indeed, for many organizations, this is they only option they have if they wish to stay in business. Many workers are very pleased with this, and some have even blasted companies who say they’ll end their remote plans when the coronavirus passes. However, as a business owner, I have a variety of issues with remote work.

Lack of Accountability

One of the biggest difficulties with remote work is the lack of accountability. Online, you’ll see all the people who support remote work argue that if you don’t trust someone, why are they working for you? But how can I possibly ever grow to trust someone I don’t have any interaction with? If the person works a remote-only job, and was hired remotely, I have no way to ever know the individual’s work ethic, whether he consistently shows up on time, or whether he plays games at the office all day. I’ve seen many people play Facebook games in their cubicles, I can only imagine what they would do if they were at home!

Difficulty in Mentoring

I currently have several interns (or, as I hear they’re called now, externs) working for me remotely. They need to complete an internship to finish the degree, and I offered to let them work for me. Unfortunately, I can’t watch what they do or easily mentor them. I don’t know when they’re stuck, and I have no way to really tell if they’re having difficulties or if they’re simply unproductive. I feel sorry for anyone working as an extern now, as I do not believe it’s possible to provide the same level of mentorship that’s possible when a team member is onsite.

Inability to Develop Social Connections

While many people may prefer to ignore it, social connections in the workplace are important. Developing relationships with a diverse pool of team members provides an employee the ability to learn from other team members, to share in the success and hardships of a project, and to engage in team-building that grows ever important as someone desires to climb the corporate ladder. Individuals who never work at the office will have a very difficult time developing the skills necessary to become the leaders of tomorrow.

Decreased Visibility

When it comes time to promote someone, do you chose the worker you’ve never met, or the individual who you see showing up early and staying late every day? The remote worker may put in just as many hours, but it will never been seen by management. Likewise, when it comes time to downsize, are you going to fire your friend or the worker three states away?

Minimized Importance of Client Interaction

Developing custom software for clients, I place a great deal of importance on relationships with my customers. I like to visit them whenever possible, see how things are going, and even socialize a bit. I view my customers as more than a source of revenue, but as the people who enable me to have a business. As such, I place a great deal of value on relationship building. With remote workers, the option for real meaningful client interaction is gone.

Why Not Outsource Everything?

If you disagree with all of the above, and you really think that remote-only is the future, then why not outsource everything to India, the Ukraine, or Latin America? If there truly is no value to being onsite, then there’s no value to me paying an American developer when I can outsource the work at a substantially reduced rate. By arguing that all jobs should be remote, you’re actually arguing that you’re way too expensive for the benefit you provide.

Conclusion

While I think remote work can be a great thing, I reject the notion that it is superior to working onsite. I look forward to returning to a normal business world where I can interact with my customers, meet for a burger with a new lead, and mentor my team in person. The remote-only world of today isn’t all it’s cracked up to be!

The NVIDIA Jetson Nano

During the last few weeks, I’ve had the opportunity to play around with the NVIDIA Jetson Nano. As an artificial intelligence enthusiast, I was very eager to see what the Jetson Nano could do, and I was not disappointed.

The Jetson Nano is a small AI computer, about the size of a Raspberry Pi. Just like the Pi, the Nano runs Linux and contains a 40-pin header for interfacing with other components. With 4 USB ports, ethernet, and HDMI, it’s a self-contained computer. What separates the Nano from the Pi, however, is the NVIDIA GPU. With 128 cores, the GPU is capable of performing floating point operations substantially faster than a typical machine. It’s those very floating point calculations that are the bulk of AI processing applications.

Taking the Nano for a spin, I downloaded their OS image and installed on an SD card. Visiting NVIDIA’s website, I found that they offered a free online course to learn the basics. Through their course, I was able to create simple AI to perform real-time image classification. Unlike a typical Haar filter generation, the Nano was able to create a classifier in minutes. And, even more exciting, the PyTorch framework they demonstrate contains pre-trained networks that allow for far fewer images than a typical Haar filter requires. Additional NVIDIA courses include video processing using C++, medical image processing, and countless other AI tasks.

What makes the Nano so exciting is just how fast it works. Having developed AI models in the past, I’m accustomed to lots of waiting. However, the Jetson Nano functions like a mini AI supercomputer. For beginners, this means you can easily generate your neural network model quickly and perform validation tests with substantially less effort than traditional computer architectures.

I highly recommend the Jetson Nano for anyone wanting to learn more about artificial intelligence or wishing to experiment with potential consumer or industrial applications with computer vision.

Master of Your Destiny

Workforce

As the economy begins to rebound from the COVID-19 pandemic, people are starting to go back to work. Unfortunately, it seems some sources are suggesting that companies have engaged in sexist behaviors by only bringing men back to work. Or have they? I asked both my wife and my daughter what they thought the reason for this apparent sexism may be and they both came to the same conclusion – women were likely staying at home to take care of their children. None of the articles I read came to this conclusion.

Shouldn’t we stomp out sexism whenever we find it? Absolutely. As my daughter enters the workforce with a STEM degree, I want her to have the same opportunities as men. As a business owner, I have a simple rule for the people I work with – they must be the most qualified people I can find. Note my lack of concern for race, gender, religious creed, etc.

Unfortunately, I see a bigger problem with the assumption that everyone is bigoted: it destroys the motivation of those who are the target of those prejudices. For instance, as women see articles about sexism in the workplace, they increasingly believe that everyone is out to get them. Likewise, the constant insistence of racism creates an environment where minorities believe they’re unable to get the job. This causes those individuals to put in less effort or even give up. After all, if the system is rigged against a person, why would they bother to try?

These notions of sexism and racism end up becoming a self-fulfilling prophecy. People give up, we see a less diverse workforce, and then point out the racial/gender makeup of the workforce to prove our conclusion.

What Do I Tell My Daughter?

When I talk to my daughter about sexism, I tell her that she is in control of her own destiny and can accomplish anything she wants to do. I tell her to ignore the reports of widespread bias and instead work hard to achieve her goals. I tell her that when she falls for the narrative that women are at a disadvantage in the workplace, she becomes the victim and is unable to achieve her goals.

Conclusion

While I have witnessed sexism in the workplace, I reject the notion that women are systematically oppressed. I believe that women are just as capable as men, and that when they begin to see themself as the victim they kill their own upward mobility through the paralysis of fear. Most importantly, I reject the politics of division and believe we all end up better when we bring the best people together – regardless of race, gender, or any other meaningless classifier.
