Declarative assembly of web applications from pre-defined concepts

Declarative assembly of web applications from predefined concepts De Rosso et al., Onward! 2019

I chose this paper to challenge my own thinking. I’m not really a fan of low-code / no-code / just drag-and-drop-from-our-catalogue forms of application development. My fear is that all too often it’s like jumping on a motorbike and tearing off at great speed (rapid initial progress), only to ride around a bend and find a brick wall across the road in front of you. That doesn’t normally end well. I’ve seen enough generations of CASE (remember that acronym?), component-based software development, reusable software catalogues etc. to develop a healthy scepticism: lowest-common denominators, awkward or missing round-tripping behaviour, terrible debugging experiences, catalogues full of junk components, inability to accommodate custom behaviours not foreseen by the framework/component developers, limited reuse opportunities in practice compared to theory, and so on.

The thing is, on one level I know that I’m wrong. To start with, there’s Grady Booch’s observation that “the whole history of computer science is one of ever rising levels of abstraction” ¹. Then there’s the changing demographic of software building. Heather Miller recently gave a great presentation on this topic, ‘The Continue reading

Fortinet Extends Cloud Security Into AWS CloudFormation

Cisco goes deep into AWS hybrid cloud with SD-WAN, security, Outposts data center support

Cisco is taking its integration with Amazon Web Services to a new level, announcing plans to integrate its SD-WAN, network services and security wares with the cloud giant's hybrid cloud environment, including its new Outposts offering. Outposts offers AWS-designed hardware that lets customers run compute and storage on premises, while connecting to AWS’s cloud services. Each Outpost has a pair of networking devices, each with 400 Gbps of connectivity and support for 1 GigE, 10 GigE, 40 GigE, and 100 Gigabit fiber connections. AWS announced the general availability of Outposts at its annual AWS re:Invent symposium, held this week in Las Vegas. To read this article in full, please click here

Amazon joins the quantum computing crowd with Braket testbed

Amazon’s initial foray into the heavily hyped world of quantum computing is a virtual sandbox in which companies can test potential quantum-enabled applications and generally get to grips with the new technology, the company announced Monday.The product is named Braket, after a system of notation used in quantum physics. The idea, according to Amazon, is to democratize access to quantum computing in a small way. Most organizations aren’t going to own their own quantum computers for the foreseeable future; they’re impractically expensive and require a huge amount of infrastructure even for the limited proof-of-concept models at the current cutting-edge.To read this article in full, please click here

The sale of PIR: The Internet Society Board Perspective

[Published on behalf of the Internet Society Board of Trustees.]

Last Friday we held a webinar with Internet Society members to answer questions about the sale of the Public Interest Registry (PIR). We were also able to unveil more details about the sale and its long-term contribution to the stability of the Internet Society (ISOC). On that call, we listened to our community members carefully. We heard the concerns regarding this decision from those who are worried about the future of the .ORG community, and who believe that we – as a non-profit and mission-driven organisation- are risking undermining our own legitimacy and responsibility to the public Internet.

First and foremost, we take the reaction from our community very seriously. Clearly, some members of the community believe that the decision to move forward with this transaction is harming our reputation. We fully understand the concerns expressed by our chapters and members, and we know that a lot of the criticism we have faced since announcing the transaction stems from the fact that we have not consulted openly, or been as clear as we should have been about what this sale would mean for both .ORG, and the Internet Society. It has always been the Board’s intention to be as open, transparent, and Continue reading

Heavy Networking 491: Real-Life Segment Routing & PCE

Heavy Networking revisits segment routing on today's episode. This time we look at segment routing as it's being use in an international science network. Our guest is Nick Buraglio. We discuss which flavor of segment routing in use, the problems the network was trying to solve and how segment routing addresses them, challenges of path computation, and more.

The post Heavy Networking 491: Real-Life Segment Routing & PCE appeared first on Packet Pushers.

Best Practice for Creating Indexes on your MySQL Tables

By having appropriate indexes on your MySQL tables, you can greatly enhance the performance of SELECT queries. But, did you know that adding indexes to your tables in itself is an expensive operation, and may take a long time to complete depending on the size of your tables? During this time, you are also likely to experience a degraded performance of queries as your system resources are busy in index-creation work as well. In this blog post, we discuss an approach to optimize the MySQL index creation process in such a way that your regular workload is not impacted.

DPDK and Open vSwitch Installation on Debian 10

DPDK stands for Data Plane Development Kit. The DPDK project consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures. Open vSwitch can use the DPDK library to operate entirely in userspace. Thanks to it, performance of Open vSwitch increases. The tutorial help you to build and install Open vSwitch using DPDK datapah on Debian 10 Buster. The second part discuses DPDK and Open vSwitch configuration and compare performance of Open vSwitch applicance with enabled/disabled DPDK.

Note: You can download my Debian 10 Buster VMDK image with installed DPDK 18.11.2 and Open vSwitch 2.11.1 for quick testiing of Open vSwitch/DPDK functionality. If you do so, you can skip the tutorial and continue with Part 2 - DPDK/Open vSwitch Configuration.
