Lean Code and API’s

API Resources

GeocodeResponse-OVER_QUERY_LIMIT

Using an Application Program Interface or API is not a new concept, is relatively simple, and easy to do.  However, developing applications using resources outside of your local controlled environment can present new challenges and opportunities.

In this instance, I was testing one of Google’s API resources and received an “OVER_QUERY_LIMIT” error message.  Although it’s not too often that this happens, apparently it can on occasion.

You have exceeded your daily request for this API.  We recommend registering for a key at the Google Developers Console:  https://console.developers.google.com/apis/credentials?project=

You typically need an API key before you can use an API such as the Google Maps Geocoding API.  For those of you thinking or wondering about security, you can place restrictions on the use of your API key.

Registering an API Key

APIs Credentials

If you already have a Google account, go to the “https://console.developers.google.com/apis/credentials?project=” link as shown in the error message above, sign in to your account and accept the terms and conditions.  You can then begin the process of creating your project and credentials.  Google will then generate an API key for your project to use in your application.

As of this writing, there are at least 184 API’s available where some of the more popular API’s include Google Drive API, Gmail API, Google Maps Android API, Google Cloud Translation API, and Google Maps Geocoding API.

Once you’ve enabled the API’s required for your project and set up your API Key, you can begin using and monitoring the services requested from your GoogleAPIs dashboard. The “Web Services > Geocoding API” page provides a simple example of getting and using the API Key in your application.

API’s can greatly simplify your application development and enables you to deploy features that would otherwise consume a lot of time and effort to implement.  The guides and documents in the API Library describe the scope of the API and provide sufficient information to begin using them to your advantage.

API Access Limits

Be aware that some API’s may have limits to the number of free “access requests” received and/or processed in a given day or over a given time period.  Users may encounter problems if requests from your site exceed this limit.  Increased access requests may be available if you are using a “fee-based” service or premium account.

For example, as of this writing, the Google Maps Geocoding API imposes the following Standard Usage Limits:  2,500 free requests per day and 50 requests per second.  A “pay-as-you-go” billing option or Premium Plan is also available with a maximum of 100,000 daily requests.

API Services

API services or resources may offer significant advantages for your application and are certainly worth an investment of your time to see what is available.  If your programming language, such as JavaScript or Python, provides a means of working with “http” requests, API’s are definitely worthy of your consideration.

API’s enable working with external resources both as a data source and for manipulating data.  The ability to programmatically work with data reduces the possibility of data entry errors and other human fallibilities.

Remember to use API key restrictions to control and prevent unauthorized access requests!  Making an attempt to use an API key from a site other than the one authorized in the restriction settings will return a “REQUEST_DENIED” status as pictured below:

Brackets Update

Brackets-Corner-ScreenShotVersion 1.12 of Brackets was released on January 29, 2018 and is now available for download.  This release introduces some exciting new features including JavaScript Refactoring, intelligent rename in file/scope feature, try catch block wrapping, one click conversion of anonymous expression / function block to arrow expression, and getter/setter creation.  More information can also be found in the release notes.

As a lightweight editor, Brackets serves as the “Goldilocks” solution for my smaller JavaScript and web page development projects.  Web page development is greatly enhanced with the live preview feature.

Although JetBrains Web Storm is my IDE of choice for larger applications, Brackets is an ideal editor for those looking to start off with something simple and easy to use.  Numerous extensions are readily available, easy to install, and will greatly enhance your experience while using Brackets.

To take advantage of the latest and greatest features, it’s important to keep your applications up to date.  These updates may fix bugs that you’ve discovered (or have yet to discover) and may also introduce some features that can save you a lot of time and effort in your development process.

Lean Code and JavaScript IDE

BracketsJavascript is one of the more popular programming languages in use today and its use and capabilities are further enhanced by a variety of available frameworks, such as Node.js and AngularJS, and other libraries.

Although you can use almost any text editor to write Javascript, a language based Interactive Development Environment (IDE) or Code Editor can greatly improve your ability to write code more efficiently and effectively.  This is especially true where syntax and case sensitive languages – like Javascript – are concerned.

I use WebStorm by JetBrains for the majority of my web-based applications, however, a number of less capable cross-platform IDE’s and editors are also available for writing JavaScript, HTML, and CSS.  One such editor is Brackets created by Adobe Systems.

Review:  The 10 best JavaScript editors” by Martin Heller, Contributing Editor, InfoWorld (May 17, 2017) presents a number of JavaScript editors for consideration of which Brackets is among them.  I prefer to use cross-platform tools wherever possible and I use a variety of IDE’s and editors that are best suited for the project at hand.

Brackets is a light-weight open-source cross-platform editor equipped with sufficient functionality to efficiently write HTML, CSS, and JavaScript code.  A number of extensions are also available to further enhance your experience using Brackets.

Extensions are often written by third-party programmers or developers and should be installed with caution.  I highly recommend researching and reading reviews by others to ensure they are worthwhile and trustworthy.

If you are just learning JavaScript or writing a quick a script, consider the simplicity of using an editor like Brackets where you can focus on writing your code rather than get bogged down with learning all the details and nuances of a full-featured IDE.

If you’re wondering what kind of programs can be written using JavaScript, HTML, and CSS, you’ll have Brackets to serve as your source of inspiration as one of the many possibilities.  For more information, visit the Brackets web page.  As of this writing, Brackets 1.11 is available for download.

The excitement of learning a new language is often met with varying degrees of chaos and confusion when selecting the right tools to get started.  I recommend starting with something simple and less distracting that will allow you to focus on the task at hand.  Brackets is one such editor.

In time, you will learn which tools will best serve your needs and you can adjust your working and coding environment accordingly.  Feature filled IDE’s and Editors will do little to serve your needs if you have yet to learn or don’t know how to program.

High-Performing Python

I was pleasantly surprised to see some very useful downloads when I opened the November 2017 issue of the Intel Developer Products Newsletter:

  • Intel Distribution for Python – Accelerate Python Performance – Powered by ANACONDA, and
  • Intel Performance Libraries – Download these free libraries today to create better, more reliable, and faster software applications.
    • Intel Data Analytics Acceleration Library (Intel DAAL)
    • Intel Math Kernel Library (Intel MKL)
    • Intel Integrated Performance Primitives (Intel IPP)
    • Intel Threading Building Block (Intel TBB)
    • Intel MPI Library (Windows Package)

Rather than write about these free offerings from Intel, click on the links above to see and choose the tools that will serve you best.  The files are relatively large and you may want to reserve your time for when and how you download them to your machine.  Versions are available for Windows, MacOS, and Linux.

Anaconda is my Python installation of choice if not simply for the ease of maintaining the many Python packages that are available.  That the Intel distribution for Python is powered by Anaconda is not surprising.

Although I’ve expressed my fair share of caution when using code libraries written by others, I have no concerns with Intel as the documentation is more than thorough.  If you’re truly interested in a comprehensive Python installation, consider this package offering from Intel.

Simply the best – Logitech’s Craft Keyboard

Craft Keyboard BoxI pre-ordered Logitech’s Craft Keyboard several weeks ago and it just arrived – a week earlier than expected!  The Craft Keyboard is compatible with Logitech’s FLOW technology and is a perfect companion to my MX Master 2S mouse.

I use computers extensively in my line of work and I’m always looking for the ultimate keyboard experience.  I was also looking for a single solution that would allow me to work on more than one machine using the same keyboard and mouse.

Logitech’s Craft keyboard coupled with the MX Master 2S mouse and Logitech’s FLOW software technology is the answer to that quest.  I can now work seamlessly between my SurfaceBook Pro and MacBook Pro machines all while using the same keyboard and mouse.  The keys on the Craft keyboard are labeled for both PC and MAC machines.

IMG_4564The top left dial, referred to as the CROWN, is one of the unique features of the Craft keyboard.  The CROWN presents either a smooth or ratchet style feel when turned depending on the current context of the application.

The touch sensitive CROWN integrates seamlessly with Microsoft Office, Adobe, and other applications.  Even browsing the web is a slightly enhanced experience.  You can perform context specific tasks from within an application by simply tapping, pressing and / or turning the CROWN.

As a premium keyboard, my expectations were high and for the most part, Logitech has delivered .  The Craft keyboard provides the best typing experience of any keyboard I have literally had the opportunity to lay my hands on.  The backlit keys are very quiet, highly responsive, and require minimal travel and effort to actuate.  The tops of the keys are slightly concave and your fingers naturally settle into them.

F6-F7 Backlight BrightnessThe backlit keys turn on immediately as your hands approach the keyboard and turn off approximately 5 seconds after you move them away.  You can use the F6 and F7 function keys to decrease or increase the brightness level of the backlit keys respectively.  There are 15 levels.  This is worth noting as the backlit keys work regardless of the ambient light levels in the room.

Simultaneously pressing the “fn” and “esc” keys toggles the shift state of the function keys between standard and assigned features.  The assigned function key features can be repurposed to perform a variety of tasks using Logitech’s Options software.

Visit Logitech’s web page for a complete review of the Craft Keyboard’s many features and capabilities.  I ordered my keyboard directly from the site and I’m extremely pleased with my purchase.

Although the Craft keyboard carries a steep price tag, when I consider the many hours that I spend working on my computers, the quality of the keyboard itself, and the new found real estate on my desk top, it’s worth every penny.

 

Increased productivity and creativity are just two of many reasons that make Logitech’s Craft Keyboard my new keyboard of choice.

Lean Code and Productivity

Writing code can be a very time-consuming process and finding ways to be more productive is typically welcomed by professional programmers.  While many new programmers are anxious to learn their language of choice, few spend any time learning about the Interactive Development Environment or IDE they are using to write their code.

Programmers can increase productivity by taking advantage of the many keyboard shortcuts that are built into their IDE or editor of choice.  Many IDE’s are designed to work on any platform and makes learning them that much more valuable.  In this context, choosing the right IDE can be just as important to your productivity as knowing the language itself.

A short list of the primary IDE’s I use includes:

  • IntelliJ IDEA HelloWorldMicrosoft:  Visual Studio 2017 (C, C#, C++),
  • ActiveState:  Komodo IDE (TCL/Tk),
  • JetBrains:
    • CLion (C++),
    • PyCharm Professional (Python),
    • IntelliJ IDEA Ultimate (Java),
    • PhpStorm (PHP),
    • RubyMine (Ruby),
  • NetBeans IDE:  NetBeans (Java).

Most of you reading this are likely familiar with the more common key combinations such as <Ctrl>+<s> to save a file, <Ctrl>+<c> to copy highlighted text, or <Ctrl>+<v> to paste text.  Many IDE providers have developed key combinations that provide much more functionality than typically offered by primitive text editors.  Extended features may range from basic editing and code navigation to code selection, code completion, code generation, code refactoring, and so much more.

IntelliJ IDEA SecretsVisual Studio 2017 (Microsoft), Komodo IDE (ActiveState), IntelliJ IDEA Ultimate and PyCharm (JetBrains) are just a few examples of IDE’s where key combinations exist to perform a wide variety of tasks.  Also knowing certain shortcuts that can be used while entering code can save a significant amount of time.

A premium IDE is well worth the investment in both money and the time required to learn it.  Extending IDE functionality to include automated code generation, code formatting, import optimization, and support for version control systems are just some of the reasons for using a premium IDE.

Once you discover the key combinations that are available to you, remembering them will be the next challenge.  Practice makes perfect and the more often you use them, the more likely it is that you will remember them.

CLionMenuDropDownIf you’re accustomed to working with your mouse when navigating the menu options inside your IDE, make note of the keyboard shortcut that may appear next to the menu option you are using as pictured in this CLion IDE drop-down menu.  If not this time, perhaps it may be worth trying the next time you find yourself reaching for the mouse to perform a task.

Aside from attempting to remember everything you read in the documentation, you can also perform a simple Google Search for “Cheat Sheets” on the language of your choice.  You will quickly discover that you are not alone when it comes to memorizing keyboard shortcuts and you will be presented with a vast array of options that are best suited for you and your specific IDE.

Increase your productivity and take advantage of all the power at your fingertips.  You will save yourself a tremendous amount of time and effort writing your code and developing your application.  By learning all there is to know about your IDE of choice, you may surprise yourself to see how much time you can save using a simple key combination that you never knew existed.

Until Next Time – STAY lean!

Logitech MX Master 2S for Power Users

Logitech Master MX 2S - FeatureWorking with multiple computers at the same time can be cumbersome at the best of times – especially where peripheral devices are concerned.  My K760 keyboard allows me to use the same keyboard on multiple machines as does my MX Master mouse.  However, neither of these devices make it possible to work seamlessly with two computers at the same time.

“There’s always a better way and more than one solution!”

~ Versalytics.org

Logitech Master MX 2S - Front Of BoxI am typically working between my SurfaceBook Pro and MacBook Pro at the same time, especially when developing applications that need to run on both.  Even the simple task of copying files or text between them takes time that I’d rather spend doing other more productive tasks.

If you’re a power user working with more than one computer, wanting to work more efficiently and effectively, and looking to free up some precious desk space, then the Logitech MX Master 2S mouse is the solution you’ve been waiting for.

Multi-Computer Control With Logitech Flow

The new Logitech MX Master 2S mouse coupled with the Logitech Flow feature is the solution that makes working seamlessly between two or three computers connected to the same WiFi network possible.  Sharing files or data between machines is as simple as moving the mouse from one screen to the other as you would when working with two monitors connected to the same machine as shown in the video below:

Logitech Master MX 2S - Back Of BoxAside from Logitech’s flow feature, there are a number of other features and improvements that the Logitech MX Master 2S brings to the table:

  • Pair with up to 3 computers and easily switch between them using the “connect” button on the bottom of the mouse.
  • Dual connectivity makes it easy to connect to your machines using either BlueTooth or Logitech’s unifying USB receiver (included).  The unifying receiver makes it possible to connect up to 6 devices using only a single USB port.
  • Completely customizable with Logitech’s “Options” software.
  • Full button and key customization.  The mouse has 7 buttons.
  • Application specific settings.
  • Gesture Button.
  • Scroll Wheel with auto-shift for speed-adaptive scrolling.
  • Battery notification and status indicator.  Note that you can use the mouse while charging it with the included USB cable that connects to a micro-USB port on the front of the mouse.
  • 70 days of battery life on a single charge compared to 40 days with the previous generation mouse.
  • Darkfield high precision (4000 DPi) sensor that allows you to work on virtually any surface – including glass.  The nominal value is set at 1000 DPi and ranges from 200 to 4000 DPi that can be adjusted in 50 DPi increments.

Logitech Master MX 2S - Inside the BoxI like the look and feel of the Logitech MX Master 2S mouse.  The mouse fits comfortably under the palm of your hand and the finger extension over the sculpted shape feels natural and relaxed.

I’m using the Logitech MX Master 2S mouse exclusively in my home office.  All facets of our business are subject to continual improvement leading to more effective and efficient use of our most valued resource – TIME.
