How gaming turned me into a coder

Monday 17th of September 2018 06:18:10 PM
I think the first word I learned to type fast—and I mean really fast—was "fireball."Like most of us, I started my typing career with a "hunt-and-peck" technique, using my index fingers and keeping my eyes focused on the keyboard to find letters as I needed them. It's not a technique that allows you to read and write at the same time; you might call it half-duplex. It was okay for typing cd and dir, but it wasn't nearly fast enough to get ahead in the game. Especially if that game was a MUD.read more

Top 5 Open Source Data Integration Tools

Businesses seeking to improve their data integration know that today's data integration software perform complex tasks. They enable applications to access data associated with other applications, and also to migrate data from one platform to another, transforming it as necessary. Given this sophistication, selecting the best data integration tool is far from easy. Adding to the complexity of the selection process: early data integration tools focused on ETL – extract, transform, and load processes. However, most of today's data integration products have much more advanced capabilities and can generally connect both on-premises and cloud-based data. Many also integrate with other data management products, such as business intelligence (BI), analytics, master data management (MDM), data governance and data quality solutions. To help sort through the complex options, the list below highlights five of the best open source data integration tools, based on vendor profile and completeness of their data integration tool set.

Red Hat: Boston, US Government, OpenShift Route, VirtualBox and More

  • BU Spark! teams up with Red Hat, hosts software design workshop
    Students traveled across Boston to its Fort Point neighborhood to attend a BU Spark! workshop about interaction design Friday. There they delved into interaction design and explored how to develop user-friendly software. BU Spark! and Red Hat Inc. hosted the Interaction Design Bootcamp jointly at Red Hat’s Boston office. BU students and Spark! Interaction design fellows attended. Red Hat is a software company that specializes in information technology and has a research relationship with Boston University that includes educational elements. The programs taught by Red Hat focus on user experience design, one of Red Hat’s specializations, according to their website.
  • Open source can spark innovative business transformation in government, Red Hat leaders say
    The federal government, largely hamstrung by legacy systems, is in need of a major digital transformation. Open source technology can be the spark that sets off that revolution, leaders from open-source software company Red Hat said Tuesday. “The types of technologies that you choose matter,” said Mike Walker, global director of Open Innovation Labs at Red Hat. “It will influence the way your business operates and open new doors to new business process, and ultimately allow you to become a software company that can achieve some of those innovations and reductions in cost and time.”
  • Kubernetes Ingress vs OpenShift Route
    Although pods and services have their own IP addresses on Kubernetes, these IP addresses are only reachable within the Kubernetes cluster and not accessible to the outside clients. The Ingress object in Kubernetes, although still in beta, is designed to signal the Kubernetes platform that a certain service needs to be accessible to the outside world and it contains the configuration needed such as an externally-reachable URL, SSL, and more. Creating an ingress object should not have any effects on its own and requires an ingress controller on the Kubernetes platform in order to fulfill the configurations defined by the ingress object. Here at Red Hat, we saw the need for enabling external access to services before the introduction of ingress objects in Kubernetes, and created a concept called Route for the same purpose (with additional capabilities such as splitting traffic between multiple backends, sticky sessions, etc). Red Hat is one of the top contributors to the Kubernetes community and contributed the design principles behind Routes to the community which heavily influenced the Ingress design.
  • VirtualBox DRM/KMS Driver Proceeding With Atomic Mode-Setting Support
    The "vboxvideo" DRM/KMS driver for use by VirtualBox guest virtual machines that has been part of the mainline Linux kernel the past several cycles will soon see atomic mode-setting support. Hans de Goede of Red Hat, who has been stewarding this driver into the Linux kernel after Oracle has failed to do so, is tackling the atomic mode-setting as his latest advancement to this driver important for a VirtualBox desktop VM experience. Published today were initial patches preparing the move to atomic mode-setting but not yet the full migration to this modern display API that offers numerous benefits.
