The Go Programming Language (Go) is an open-source programming language sponsored by Google and created by Robert Griesemer, Rob Pike, and Ken Thompson that makes it easy to build simple, reliable, and efficient software.
Go has gained popularity since it was first announced in 2009, and it’s now being used by many companies worldwide and for a variety of applications; Dropbox, Google, SoundCloud, CloudFlare, Docker and Cloud Foundry are some of the Go programming users.
Like any technology, though, it has its adherents and critics. Here are some key benefits and perceived drawbacks of the language as told by experts familiar with it.
- It is fast. And not only fast in the sense that programs written in it run fast when compared to other common languages; but also fast in the sense that its compiler can compile projects in the blink of an eye. You can even edit and run Go programs directly on the Web.
- It is a garbage-collected language. This puts less pressure on the developer to do memory management, as the language itself takes care of most of the grunt work needed.
- It has built-in concurrency, which allows parallelism in an easier way than is possible in other languages. Go has the concept of goroutines to start concurrent work and the concept of channels to permit both communication and synchronization.
- Go has documentation as a standard feature. That makes it easier for developers to document their code and generate human-readable data out of source code comments.
- Go has a rich standard library which covers a lot of areas. In fact, Go is probably the only language that can claim to have a fully working Web server as part of its standard library.
- Go’s built-in build system is both elegant and simple. No need to mess with build configurations or makefiles.
- Go is still a very young language and has a very young ecosystem. This means there aren’t many libraries for it yet, leaving developers to write libraries themselves. There is also a shortage of books and online courses on the language.
- Go is simple to the point of being superficial. Go’s simplicity is mostly superficial, and in its effort to find simplicity, it threw away decades of valuable programming language progress.
- Although Go is a high-level language, it still has low-level features such as pointer-arithmetic which does not rule out the chance of doing systems and OS programming.
- Go’s tooling is really weird, on the surface it has some really nice tools, but a lot of them, when you start using them, quickly show their limitations.
- It is still not so easy to learn Go and it’s difficult to handle errors in it.
What is your attitude to Go? Is it worth learning? What do you think are Go’s advantages and disadvantages? Can you tell us about a real use you have given to this programming language? Please, feel free to share your thoughts here below.
At one time, universities and colleges were institutes of higher learning for those who were passionate about acquiring knowledge. Today, education discussions tend to to center around how much individuals can make with their degree. Thanks to the Internet there are still places that offer open learning initiatives designed to help a new generation of technologists succeed.
Let’s start reviewing the free online courses to grow your tech skills.

The use of health apps has skyrocketed in 2014. Flurry, a mobile analytics company, has followed over 6,800 health and fitness-related apps, and sees a growth of 62% based on measurements of the number of times the app is opened and used. Overall growth rate apps otherwise is 33%.
By 2017 the app market is predicted to reach 26 billion users. Among its key drivers is the world’s aging population with its increasing need for medical care. In the United States alone, Tighe notes, almost 20 percent of Americans will be older than 65 by 2030, making them more vulnerable to Alzheimer’s, cardiovascular disease, and other age-associated conditions. This changing landscape is forcing to create new ways to monitor people health and provide assistance with making health wise choices. And here mobile medical apps have already proved efficient and thus are gaining more and more popularity.
This boom has been also supported by most global IT corporations such as Google, Apple, Microsoft and Facebook. So here are some recent actions in that area showing that these companies treat this market segment really seriously:
- Google recently launched Google Fit and directed towards more consumers within training and nutrition.
- Apple has partnered with the company Epic. Since Epic handles over 51% of the medical records in the US, it gives Apple a very solid position in healthcare sector. Apple has, in iOS8, also included a personal health platform, HealthKit, which integrates other applications and gathers information for the user will appear in Apple Health app.
- Microsoft invests in a separate solution and will with Microsoft Health Vault offer a platform where people can gather, store, share and use health data online.
- Facebook has integrated MapMyFitness so friends can cheer on each other, share results and compete against each other. This has also contributed to the large increase in the use of health and Fitness app, where distribution is large via the social networking channel.
There is even an opinion that the increased use of health and fitness apps will destroy the market for wearables. It’s hard for them to compete with mobile apps, as the number of smartphone users is really big. So when the software is already integrated into smartphones they automatically become efficient devices for collecting health data. To put it short, the benefits of using mobile apps to wearable medical-devices include 1/ cost savings because there is no need to develop a completely new device, 2/ enhancing existing platforms by adding more sophisticated sensing and data capabilities, 3/ using an interface that consumers know well and is already part of their everyday life.
Healthcare IT outsourcing
Health apps are built up not only by global IT companies, but also by healthcare providers to be used by doctors, specialists and by patients, of course. And here healthcare organizations increasingly take over the idea that IT outsourcing can help them bring their apps faster to the market while they could focus on their core activities.
This tendency has also been stimulated by changing government regulations concerning hospitals and clinics in lots of countries. And while some organizations are broadly outsourcing a mobile applications development, others are handing out the responsibility of IT management and overseeing their entire IT infrastructure.
The global healthcare IT outsourcing market is growing continuously. According to an article by Nearshore Americas, a recent study made by the Everest group states that the global healthcare IT outsourcing market is increasing at a compound annual growth rate of 12%. This gives us an insight on how much demand healthcare institutions now place on IT outsourcing services. According to TechNavio IT outsourcing in the global healthcare and life sciences sector is expected to increase at a compound annual growth rate of 8.6% through 2019.
Among the trends to watch besides going mobile, there is hosting on the cloud by health-related organizations to make their operations safer, using analytics-as-a-service technologies due to growing interest in Big Data, etc. Therefore 70% of healthcare organizations worldwide are expected to invest in consumer-facing mobile applications, wearables, remote health monitoring, and virtual care.
So the world has been ready for a while to embrace healthcare apps and demand for them is not going to slow down any time soon. Among the top medical apps they call CDC Vaccine Schedules, Family Practice Notebook, ASCVD Risk Estimator, etc.
What health-related apps have you tried and which ones do you use daily? Thank you for sharing!
The infrastructure-as-a-service (IaaS) market has exploded in recent years. Google stepped into the fold of IaaS providers, somewhat under the radar. The Google Cloud Platform is a group of cloud computing tools for developers to build and host web applications.
It started with services such as the Google App Engine and quickly evolved to include many other tools and services. While the Google Cloud Platform was initially met with criticism of its lack of support for some key programming languages, it has added new features and support that make it a contender in the space.
Here’s what you need to know about the Google Cloud Platform.
Google recently shifted its pricing model to include sustained-use discounts and per-minute billing. Billings starts with a 10-minute minimum and bills per minute for the following time. Sustained-use discounts begin after a particular instance is used for more than 25% of a month. Users receive a discount for each incremental minute used after they reach the 25% mark.
2. Cloud Debugger
The Cloud Debugger gives developers the option to assess and debug code in production. Developers can set a watchpoint on a line of code, and any time a server request hits that line of code, they will get all of the variables and parameters of that code. According to Google blog post, there is no overhead to run it and “when a watchpoint is hit very little noticeable performance impact is seen by your users.”
3. Cloud Trace
Cloud Trace lets you quickly figure out what is causing a performance bottleneck and fix it. The base value add is that it shows you how much time your product is spending processing certain requests. Users can also get a report that compares performances across releases.
4. Cloud Save
The Cloud Save API was announced at the 2014 Google I/O developers conference by Greg DeMichillie, the director of product management on the Google Cloud Platform. Cloud Save is a feature that lets you “save and retrieve per user information.” It also allows cloud-stored data to be synchronized across devices.
The Cloud Platform offers two hosting options: the App Engine, which is their Platform-as-a-Service and Compute Engine as an Infrastructure-as-a-Service. In the standard App Engine hosting environment, Google manages all of the components outside of your application code.
The Cloud Platform also offers managed VM environments that blend the auto-management of App Engine, with the flexibility of Compute Engine VMs.The managed VM environment also gives users the ability to add third-party frameworks and libraries to their applications.
Google Cloud Platform networking tools and services are all based on Andromeda, Google’s network virtualization stack. Having access to the full stack allows Google to create end-to-end solutions without compromising functionality based on available insertion points or existing software.
According to a Google blog post, “Andromeda is a Software Defined Networking (SDN)-based substrate for our network virtualization efforts. It is the orchestration point for provisioning, configuring, and managing virtual networks and in-network packet processing.”
Containers are especially useful in a PaaS situation because they assist in speeding deployment and scaling apps. For those looking for container management in regards to virtualization on the Cloud Platform, Google offers its open source container scheduler known as Kubernetes. Think of it as a Container-as-a-Service solution, providing management for Docker containers.
8. Big Data
The Google Cloud Platform offers a full big data solution, but there are two unique tools for big data processing and analysis on Google Cloud Platform. First, BigQuery allows users to run SQL-like queries on terabytes of data. Plus, you can load your data in bulk directly from your Google Cloud Storage.
The second tool is Google Cloud Dataflow. Also announced at I/O, Google Cloud Dataflow allows you to create, monitor, and glean insights from a data processing pipeline. It evolved from Google’s MapReduce.
Google does routine testing and regularly send patches, but it also sets all virtual machines to live migrate away from maintenance as it is being performed.
“Compute Engine automatically migrates your running instance. The migration process will impact guest performance to some degree but your instance remains online throughout the migration process. The exact guest performance impact and duration depend on many factors, but it is expected most applications and workloads will not notice,” the Google developer website said.
VMs can also be set to shut down cleanly and reopen away from the maintenance event.
10. Load balancing
In June, Google announced the Cloud Platform HTTP Load Balancing to balance the traffic of multiple compute instances across different geographic regions.
“It uses network proximity and backend capacity information to optimize the path between your users and your instances, and improves latency by connecting users to the closest Cloud Platform location. If your instances in one region are under heavy load or become unreachable, HTTP load balancing intelligently directs new requests to your available instances in a nearby region,” a Google blog post said.
