Do you need an Architect in a Software Company?
This may be a dangerous question to ask for someone whose role is that of an
Architect, but I think it is a valid question for an Architect to ask. This is
particularly true in the software industry where the role is interpreted in many
different ways. In some cases, an Architect may work in an established
enterprise company and hand down instructions on technology stacks to the
developers. At the other extreme an Agile development team may work without the
involvement of an Architect. Neither

Log Analysis for Containers
Introduction
The IT and DevOps world has come a long way with infrastructure.
Virtualization revolutionized our ability to quickly deploy an application and
scale up services when needed, paying only for the computing power used. Over
the last few years, agile methodologies and continuous delivery have pushed VMs
to their limits. Many teams still repeatedly use a single VM for releases and
testing. Production VMs rarely change unless something goes seriously wrong. At
the pace software develop

Common Angular Routing Challenges
When it comes to frameworks, no one is perfect. As we migrate the Logentries
application from legacy code to Angular, we’ve encountered a few interesting
challenges along the way that we’ve enjoyed investigating and resolving. While
specific challenges often depend on your project and migration strategy, the aim
of this post is to share our solutions to problems one may encounter when
migrating an app to Angular. In particular, I’ll focus on how Angular handles

What is Elastic Logging?
We’re all familiar with the concept of “Elasticity” – the way cloud
infrastructures can automatically react to their required workloads, scaling
resources up or down as needed. While elastic environments provide us with much
needed flexibility, they have also historically presented challenges when trying
to monitor activity from their ephemeral components. Automatically accounting
for new nodes can be tricky while scaling up. And when scaling down, data
associated with these nodes is potentially

State of Log Management for AWS
Introduction
The Log Management [https://www.rapid7.com/fundamentals/what-is-log-management/]
industry was traditionally driven by regulatory compliance and security concerns
resulting in a multi-billion dollar market focused on security and information
event management (SIEM) solutions. However, log management has evolved into a
market that is focused on both the management and analytics of log data. Log
management technologies are becoming more powerful and dynamic, allowing for
data to be

How to Add a GPS Time Source to ntpd
USB GPS dongles have come down significantly in price in recent years and I
picked one up to play with recently.
Apart from using a GPS module to report your latitude, longitude, altitude and
time for mapping applications, it’s also possible to feed the time information
to ntpd as a back-up time source or as a highly accurate time source depending
on the GPS module you end up getting.

Playing with Java 8's Completable Futures
Of the many additions to Java 8 such as the Stream API
