Expanding the AWS Cloud: Introducing the AWS Europe (London) Region

All Things Distributed

In November 2015, Amazon Web Services announced that it would launch a new AWS infrastructure region in the United Kingdom.

What Makes A Senior Software Developer?

Professor Beekums

UPDATE 2017-01-01: This post has a follow up. Most engineering organizations will have to answer the question: “What makes a software developer a senior developer?” This is a challenging question because it is extremely subjective. Search for the answer on the internet and you will get many different answers. Some will contain criteria that are also subjective themselves which adds additional difficulty to the question.

My Activity Report For 2016

The Polyglot Developer

It has been a long year being an advocate of technology and I thought it would be a good idea to share everything that has happened to The Polyglot Developer and all of its networks. Last year, in 2015, I started a tradition of sharing my WordPress, YouTube, and course statistics. We are approaching the end of the year and it is that time again. Below you’ll find statistics that may help you if you’re planning on creating a blog or developing a course.

Design Patterns: Queue-Based Load Leveling Pattern

cdemi

Modern software usually involves running tasks that invoke services. If the service is subjected to intermittent heavy loads, it can cause performance or reliability issues. If the same service is utilized by a number of tasks running concurrently, it can be difficult to predict the volume of requests to which the service might be subjected at any given point in time.

Transforming Development with AWS

All Things Distributed

In my keynote at AWS re:Invent today, I announced 13 new features and services (in addition to the 15 we announced yesterday). My favorite parts of James Bond movies is are where 007 gets to visit Q to pick up and learn about new tools of the trade: super-powered tools with special features which that he can use to complete his missions, and, in some cases, get out of some nasty scrapes.

Beware of Developers Who Do Negative Work

Professor Beekums

UPDATE 2016-12-25: This post has an important follow-up. At some point in every software developer’s career, we work with someone who does negative work. The notion of negative work may sound a little strange. Someone can do no work by just… not working. How does negative work happen? One example of this is an awful developer that was once at the same company as me.

Create A URL Shortener With Golang And Couchbase NoSQL

The Polyglot Developer

Continuing down the road of Golang development I thought it would be a cool learning example to develop a URL shortener application similar to that of TinyURL or Bitly. I think these are great examples because not only does it teach you how to develop a RESTful API that uses a datasource, but it also challenges you to think critically when it comes to the algorithms.

Design Patterns: Competing Consumer Pattern

cdemi

Building on the Queue-Based Load Leveling Pattern , the Competing Consumer Pattern enables a system to process multiple messages concurrently to optimize throughput, to improve scalability and availability, and to balance the workload. During the lifetime of an application, the number of requests may vary significantly over time. Using a single instance of the consumer service might cause that instance to become flooded with requests.

Memory Latency on the Intel Xeon Phi x200 “Knights Landing” processor

John McCalpin

The Xeon Phi x200 (Knights Landing) has a lot of modes of operation (selected at boot time), and the latency and bandwidth characteristics are slightly different for each mode. It is also important to remember that the latency can be different for each physical address, depending on the location of the requesting core, the location of the coherence agent responsible for that address, and the location of the memory controller for that address.

Should You Hire a Bootcamp Graduate?

Professor Beekums

Developer/coding bootcamps are incredibly popular right now. That should not be a surprise to anyone. Software development is an incredibly lucrative field. There is a much greater demand for talent than there is supply. I’ve seen that from both the hiring side and the job applicant side. It makes sense that a lot of folks out there are interested in becoming software developers.

Create A Real Time Chat App With Golang, Angular, And Websockets

The Polyglot Developer

I’ve been hearing a lot about websockets lately and how they can accomplish real time communication between applications and servers. They act as a compliment and possible alternative to RESTful APIs that have been around for significantly longer. With websockets you can do real time messaging for things like chat, communication with IoT, gaming, and a whole lot of other things that need instant communication between clients and the server.

The post on “Beware of Developers Who Do Negative Work” was both enjoyed by many and highly criticized by many. I’m usually fine with criticism, but one point really stung. A lot of the criticism denounced the idea that junior developers do negative work. They need mentoring and coaching, not to be frightened and have their insecurities targeted by callous bloggers such as myself.

Determine If A Number Is Prime Using The Go Programming Language

Almost two years ago I wrote an article explaining how to determine if a number is prime or not using JavaScript. It turns out this article became more popular than I thought it would, and if I had to guess, it might be because it is a good computer science and overall interview question for new career developers. I thought it would make sense to revisit the post, but this time focus on accomplishing the task with the Go programming language instead of JavaScript.
