Link Roundup, 1-26-15: Centralized Architecture

Centralized Architecture

At Phys.org, Dr. Norbert Aschenbrenner recently wrote about the First Series Production Vehicle with Software Control. Siemens and partners are developing information and communications technology for electric cars, and their first production vehicle uses a central electronics and software architecture called RACE. This centralized architecture is intended to reduce development time and make it easier to add new functions later. This SATURN link roundup offers several recent blog posts and a podcast on the topic of centralized architecture.

Selecting the Right Computing Architecture for Your GIS: Dave Peters at Esri Insider offers some advice on how to choose between centralized and distributed architectures.

IoT Drives Business Decisions: In a podcast from the 2014 IoT Summit, Gary Butler, Chairman and CEO of Camgian Microsystems, and Gary Audin, President of Delphi, discussed two approaches to connecting the Internet of Things (IoT), centralized architectures and architectures distributed at the network edge.

Link Roundup, 1-20-15: Clouds at Hyperscale

Clouds at Hyperscale

For media services everywhere, January is the time to write summaries of the previous year and make forecasts about the next one. Lisa Wirthman of Forbes Magazine helps us transition to the new year with How the Top 5 Cloud Trends of 2014 Will Impact the Enterprise in 2015. The fourth of Wirthman’s five trends is about the maturing cloud market in 2014 and the growth of a few cloud providers operating at a global scale in 2015. This SATURN link roundup offers a few recent blog posts on clouds at hyperscale.

A Rare Peek Into The Massive Scale of AWS: Amazon Web Services has revealed the size and scope of its cloud, and Timothy Prickett Morgan at EnterpriseTech reports that it is really, really big. Morgan runs through some of the numbers and discusses the datacenter architecture of the AWS cloud. You can also watch AWS Senior Vice President Andy Jassy’s keynote talk from the AWS Re:Invent 2014 Conference. Continue reading

Trends and New Directions in Software Architecture, by Linda Northrop
1:30 PM ET – 2:15 PM ET

Software architecture has enormous influence on the behavior of a system. For many categories of systems, early architectural decisions can be a greater influence on success than nearly any other factor. After more than twenty years of research and practice, the foundations for software architecture have been established and codified, but challenges remain. Among other trends, increased connectivity, a shift to the cloud and to mobile platforms, and increased operational and market tempos have precipitated the need for changes in architectural practices and decisions. The first talk shares a perspective on the trends influencing the need for change, the related architectural challenges, and the applicable research and practices.

Link Roundup, 1-5-15: Refactoring

Refactoring

In December 2014, Andre Infante of CoinReport wrote about a Bitcoin developer’s warning that the rapid development of Bitcoin software may be “introducing consensus bugs.” In Peter Todd Warns of Potential for Accidental Bitcoin Forks, Infante describes how the pace and scale of refactoring may have created a fork in the development. If the fork is not corrected, the network may not be able to achieve consensus about official versions of events, which could wreak havoc for a payment system. This link roundup offers several recent blog posts and a conference presentation on the topic of refactoring.

Sacrificial Architecture: Martin Fowler of ThoughtWorks, and author of Refactoring, explains why he hopes that in a few years you’ll need to throw away the code you are creating today.

Architecture Seams: Jean Barmash at Hello FooBar! expands Michael Feathers’ term seam from the book Working Effectively with Legacy Code from code to architecture, then discusses how to exploit architecture seams in a large-scale refactoring project. Continue reading

Architectural Concepts Podcast: SATURN 2015 and Why You Should Plan to Attend

I had the pleasure of talking about our plans for SATURN 2015 with Bett Correa and Russ Miller, longtime friends of SATURN, on their Architectural Concepts Podcast.

Link Roundup, 12-12-14: Cross-Language and Cross-Platform Development

In a Huffington Post article titled “What Global Warming, Energy Efficiency and Erlang Have in Common,” Noah Gift says, “Hidden in the discussion of rising energy costs and consumption in datacenters is the selection of software language.” Gift’s emphasis is on how the constraints many languages have limit them to one processor and how the languages used to write software can affect the way that processors use energy. This inefficiency would seem to extend backward from running software to developing software. Nowadays, developers must contend not only with multiple desktop platforms but also with multiple mobile platforms, and do so in multiple languages. This week’s link roundup highlights some tools for simplifying the processes of developing across languages and platforms.

Apache Thrift: The Apache Thrift software framework combines a software library with a code-generation engine, and the compiler generates code that can communicate across programming languages, enabling efficient development of scalable backend services. A white paper discusses motivations and design choices. Continue reading

Why You Should Submit Your SATURN 2015 Proposal NOW

At SATURN, we hate the idea that a good talk might be rejected because its abstract is unclear or doesn’t answer questions that the reviewers might ask. Good talks should not be rejected because the proposal is not absolutely perfect.

So last year we introduced an early-acceptance deadline for speaker submissions, and it worked out really well. The quality of presentations was higher than in years past, and we overcame the dreaded Student’s Syndrome–everyone waiting until the night before to submit.

But this year we asked ourselves, Can we give even more opportunities? Can we make the proposal process even more friendly?

For SATURN 2015, we have adopted a rolling-acceptance approach.This means that the review committee is continuously reviewing speaker proposals as they are submitted. When reviewers see a great proposal, it is accepted immediately and added to the technical program. Authors of other proposals get detailed feedback about what the reviewers are thinking and what questions they have, so they can revise and resubmit.

No longer will you have to hire a soothsayer to guess what the committee might have been thinking, only to have the feedback too late to do anything about it.

We have been accepting speaker proposals since October though the website was lagging a bit. That has been corrected and the full list of speakers accepted is now available. The line-up so far is looking stellar.

The final deadline for acceptance is January 16, but that doesn’t mean you should wait until the last minute!  If you want the opportunity to be accepted early or to receive feedback for improving your proposal for resubmission, you should submit your proposal right now.

SATURN is a conference for working professionals. Our rolling acceptance and early feedback this year should make it easier for you to speak at SATURN, so don’t delay!
