Redirection occurs anytime your user attempts to load a page with a given URL, but is instead sent to a site that uses a slightly different address. There are many reasons why you might consider redirection: The original site has moved, and you want to send the user to the most current location. You want to track clicks and log pages that refer users to your site/sites.

SOA or Service Oriented Architecture is a software development framework employed for building a business application by using a number of small independent services. So, with this context, what is a service? A service is a component of an application that performs one particular task. For example, a payment service is used for online payments, and an authentication service is used for securely logging users into their application.

Quality assurance (QA) testing is an essential part of the software development process, involving the identification of bugs in products to ensure they are as error-free as possible. Unfortunately, there are also a lot of misconceptions about what QA testing and QA services actually entail. Today, many companies engage in software QA outsourcing , sometimes using offshore testing services, while some still keep their QA services in-house.

Dynatrace news. Applications often deliver frustrating user experiences that result from bad performance, poor operational health, or unexpected errors. In some instances, however, bad user experience stems from usability issues in product design or development. Examples of such issues include buttons that don’t work as expected, visuals that look like buttons but are indeed only labels, and so on.

The ANY aggregate is not something we can write directly in Transact SQL. It is an internal only feature used by the query optimizer and execution engine. I am personally quite fond of the ANY aggregate, so it was a bit disappointing to learn that it is broken in quite a fundamental way. The particular flavour of 'broken' I am referring to here is the wrong-results variety.

My last post showed how the API Science API can be utilized to create a graphical analysis of API performance binned by the hour of the day. In this post, we use data extracted from the API Science API to analyze the performance of an API by day of the week. This type of analysis would be useful for a company whose product experiences surges of usage on different days of the week (for example, weekends versus work days).

Photo taken by Adrian at the Park Hyatt NingBo, China I recently read Annaka Harris’ new book Conscious about the mysteries and nature of consciousness and had an epiphany. What we do to make our computer systems observable is actually closely related to consciousness. The essential quality of conciseness is a model of the system. That model is fed with information and interrogated about the overall health and behavior of the system.

As a programmer we have written codes that ideally solves a problem, but do we take note of the performance when it comes to solving a problem, or do we just feel comfortable with “My code works?" Don’t stop there, take your thinking bigger than “My code works” to “Can my code solve a huge problem?” as this is where thinking on a performance level comes in.

Within 24 hours of last month's post on regulation of technology firms , new anti-trust probes into Google and Apple were reported by the Wall Street Journal. Around the same time, Renault stirred up a hornets nest of regulatory furore over its proposed (and subsequently withdrawn) merger with Fiat Chrysler. It's worth examining the prior in the context of the latter to understand why the regulatory free ride Big Tech Media firms enjoy will continue for quite some time to come.

Most, if not all, Java and Android developers have come across logging requirements in their application. The most commonly known Java logging frameworks are Log4j2 , Logback , and JUL (Java Util Logging), and most people have probably used SLF4J, the abstraction on top of these logging frameworks. A lesser-known logging framework is TinyLog, and soon its successor, TinyLog 2.
