  • ScyllaDB takes on Amazon with new DynamoDB migration tool

    There are a lot of open-source databases out there, and ScyllaDB, a NoSQL variety, is looking to differentiate itself by attracting none other than Amazon users. Today, it announced a DynamoDB migration tool to help Amazon customers move to its product.

  • ScyllaDB Announces Alternator, an Open Source Amazon DynamoDB-Compatible API

    ScyllaDB today announced the Alternator project, open-source software that will enable application- and API-level compatibility between Scylla and Amazon’s NoSQL cloud database, Amazon DynamoDB. Scylla’s DynamoDB-compatible API will be available for use with Scylla Open Source, supporting the majority of DynamoDB use cases and features.

  • ScyllaDB Secures $25 Million to Open Source Amazon DynamoDB-compatible API

    Fast-growing NoSQL database company raises funds to extend operations and bring new deployment flexibility to users of Amazon DynamoDB.

  • ScyllaDB powers up Alternator: an open Amazon DynamoDB API

    Companies normally keep things pretty quiet in the run up to their annual user conferences, so they can pepper the press with a bag of announcements designed to show how much market momentum and traction that have going.

    Not so with ScyllaDB, the company has been dropping updates in advance of its Scylla Summit event in what is perhaps an unusually vocal kind of way.

    [...]

    Scylla itself is a real-time big data database that is fully compatible with Apache Cassandra and is known for its ‘shared-nothing’ approach (a distributed-computing architecture in which each update request is satisfied by a single node –processor/memory/storage unit to increase throughput and storage capacity.

  • Percona Announces Full Conference Schedule for Percona Live Open Source Database Conference Europe 2019

    The Percona Live Open Source Database Conference Europe 2019 is the premier open source database event. Percona Live conferences provide the open source database community with an opportunity to discover and discuss the latest open source trends, technologies and innovations. The conference includes the best and brightest innovators and influencers in the open source database industry.

  • Thwarting Digital Ad Fraud at Scale: An Open Source Experiment with Anomaly Detection

    Our experiment assembles Kafka, Cassandra, and our anomaly detection application in a Lambda architecture, in which Kafka and our streaming data pipeline are the speed layer, and Cassandra acts as the batch and serving layer. In this configuration, Kafka makes it possible to ingest streaming digital ad data in a fast and scalable manner, while taking a “store and forward” approach so that Kafka can serve as a buffer to protect the Cassandra database from being overwhelmed by major data surges. Cassandra’s strength is in storing high-velocity streams of ad metric data in its linearly scalable, write-optimized database. In order to handle automation for provisioning, deploying, and scaling the application, the anomaly detection experiment relies on Kubernetes on AWS EKS.

  • SHADERed 1.2.3 Released With Support For 3D Textures & Audio Shaders

    SHADERed is the open-source, cross-platform project for creating and testing HLSL/GLSL shaders. While a version number of 1.2.3 may not seem like a big update, some notable additions can be found within this new SHADERed release.

Debian and Ubuntu Leftovers

  • Ritesh Raj Sarraf: Bpfcc New Release

    bpfcc version 0.11.0 has been uploaded to Debian Unstable and should be accessible in the repositories by now. After the 0.8.0 release, this has been the next one uploaded to Debian.

  • Utkarsh Gupta: Joining Debian LTS!

    Back during the good days of DebConf19, I finally got a chance to meet Holger! As amazing and inspiring a person he is, it was an absolute pleasure meeting him and also, I got a chance to talk about Debian LTS in more detail. [...] I had almost no idea what to do next, so the next month I stayed silent, observing the workflow as people kept committing and announcing updates. And finally in September, I started triaging and fixing the CVEs for Jessie and Stretch (mostly the former). Thanks to Abhijith who explained the basics of what DLA is and how do we go about fixing bugs and then announcing them. With that, I could fix a couple of CVEs and thanks to Holger (again) for reviewing and sponsoring the uploads! :D

  • Ubucon Europe 2019 in local media

    News from the new Ubuntu distribution, the exploration of the several platforms and many “how to”, rule the 4-days agenda where the open source and open technologies are in the air. The Olga Cadaval Cultural centre in Sintra, is the main stage of a busy agenda filled with several talks and more technical sessions, but at Ubucon Europe there’s also room for networking and cultural visits, a curious fusion between spaces full of history, like the Pena Palace or the Quinta da Regaleira, and one of the youngest “players” in the world of software. For 4 days, the international Ubuntu Community gathers in Sintra for an event open to everyone, where the open source principles and open technology are dominating. The Ubucon Europe Conference begun Thursday, October 10th, and extends until Sunday, October 13th, keeping an open doors policy to everyone who wants to Afterall, what is the importance of Ubucon? The number of participants, which should be around 150, doesn’t tell the whole story of what you can learn during these days, as the SAPO TEK had the opportunity to check this morning. Organised by the Ubuntu Portugal Community, with the National Association for Open Software, the Ubuntu Europe Federation and the Sintra Municipality, the conference brings to Portugal some of the biggest open source specialists and shows that Ubuntu is indeed alive, even if not yet known by most people, and still far from the “world domain” aspired by some.

Devices/Embedded: Win Enterprises and Raspberry Pi 4

  • Win Enterprises unveils Atom-based LAN gateway and compact SBC

    Win Enterprises unveiled a fanless “PL-82000” networking gateway with 6x GbE and 2x SFP ports based on an Atom C3000. It also launched a Raspberry Pi sized “MB-5000” SBC that runs Ubuntu or Win 10 on Intel Apollo Lake. We tend to forget Win Enterprises because as its name suggests, the company typically sticks to Windows-supported products. Yet, they have increasingly produced barebones products without listed OS support, such as the new PL-82000 networking appliance, as well as Linux supported systems such as the MB-5000 SBC announced back in June. (In 2017, we covered an Intel Bay Trail based MB-80580 SBC and Win IoT-380 Gateway with Linux support.)

  • Raspberry Pi 4 PCI Express: It actually works! USB3, SATA… GPUs?

    Recently, Tomasz Mloduchowski posted a popular article on his blog detailing the steps he undertook to get access to the hidden PCIe interface of Raspberry Pi 4: the first Raspberry Pi to include PCIe in its design. After seeing his post, and realizing I was meaning to go buy a Raspberry Pi 4, it just seemed natural to try and replicate his results in the hope of taking it a bit further. I am known for Raspberry Pi Butchery, after all.

  • Raspberry Pi 4 B+ - PCI Express

    Why did I do it? Because I wanted to see if it can be done. Because Raspberry Pi 4 might be the cheapest device that is PCIe capable after a relatively minor modification (if I didn't lift the capacitors when desoldering the VL805, this is literally 12 soldering points). That, in turn, can be quite handy for developing own PCIe cores for various FPGA based experiments.

    I'm sharing it to allow people to learn from this - and to dispel the myth that PCIe is somehow out of reach of hobbyists due to some concerns over signal integrity or complexities. Stay tuned for more Pi4/PCIe experimentation!
