Fast Convergence and the Fast Reroute – Definitions/Design Considerations in IP and MPLS

Fast Convergence and the Fast Reroute Network reliability is an important design aspect for deployability of time and loss sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology.   Fast reaction is essential […]

AWS offers Alexa developers free cloud credits

Developers interested in extending the capabilities of Amazon’s Alexa virtual assistant have some more free tools in their arsenal, thanks to a program the company announced Wednesday.Developers with an active Alexa skill --  a service that expands the capabilities of the virtual assistant -- can apply for $100 in Amazon Web Services credits every month to help pay for what they’ve built. After that, they can receive up to $100 per month in additional credits if they incur usage charges for their skills.The credits are meant to build on AWS’s existing Free Tier, which offers developers a small bundle of free services every month, but charges them for any usage that goes over those low caps. According to a blog post by Amazon CTO Werner Vogels, the move is supposed to make it free for developers to operate most Alexa skills.To read this article in full or to leave a comment, please click here

Appeals court rules Americans have no legal recourse if hacked by foreign governments

Put aside the matter of Russian interference in our presidential election to instead consider this scenario: If Vladimir Putin ordered his government-employed hackers to plant spyware on your personal computer – stealing all your data and even recording your Skype calls – you would have no access to any legal remedy in the U.S. court system. Preposterous, you say? That’s the law, according to the United States Court of Appeals for the District of Columbia Circuit, which yesterday upheld a lower court decision denying even a day in court to an American citizen who moved here from Ethiopia 30 years ago and was victimized by that country’s government in the exact fashion described above.To read this article in full or to leave a comment, please click here

Worth Reading: Redundancy does not imply fault tolerance

It’s a tough life being the developer of a distributed datastore. Thanks to the wonderful work of Kyle Kingsbury (aka, @aphyr) and his efforts on Jepsen.io, awareness of data loss and related issues in the face of network delays and partitions is way higher than it used to be. Under the Jepsen tests, every single system tested other than ZooKeeper exhibited problems of some kind. But many teams are stepping up, commissioning tests, and generally working hard to fix the issues even if they’re not all there yet. —the morning paper

SAP adds new features to Vora and readies a cloud version

SAP has added some new capabilities to SAP Vora, its in-memory distributed computing system based on Apache Spark and Hadoop. Version 1.3 of Vora includes a number of new distributed, in-memory data-processing engines, including ones for time-series data, graph data and schema-less JSON data, that accelerate complex processing. Common uses for the graph engine might be analyzing social graphs or supply chain graphs, said Ken Tsai, SAP's head of product marketing for database and data management.

Linux Systemd & Golang Services using Kardianos Service

This week I have done something new, but I found myself dealing with a ‘zero knowledge’ situation or something I like to call ZKS. This is one of those ones where it’s fun, but it also feels a bit stressy as there was enough rope to hang myself with.

That something new is Systemd, which is a Linux operating system thing that manages the initialisation of user things. To speak about this more technically, it is a drop in replacement ‘init’ system that starts services and sets up the user environment. Wikipedia has this to say about it:

Systemd is an init system used in Linux distributions to bootstrap the user space and manage all processes

For those lacking historic knowledge around systemd, it previously many upset devs and administrators, which in turn setup a site called ‘boycottsystemd’ which looks to be offline. They said it flies in the face of doing it the Unix way, which is (to summarise) do one thing and do it well. Systemd is now the default init system for Ubuntu 15x and newer releases. Can’t be that bad…right?

Whilst this is not a complete education around systemd, it’s popular and is reasonably easy to Continue reading
