  • With Strato, Esgyn Sends Hybrid Data Workloads to the Cloud
    451 RESEARCH REPRINT REPORT REPRINT With Strato, Esgyn sends hybrid data workloads to the cloud JAMES CURTIS 01 NOV 2018 Esgyn is an emerging player in the hybrid processing space that sells a SQL-based query engine based on the Apache Trafodion project. Now the company is introducing a managed cloud service to handle hybrid workloads as it looks to spur US adoption. THIS REPORT, LICENSED TO ESGYN, DEVELOPED AND AS PROVIDED BY 451 RESEARCH, LLC, WAS PUBLISHED AS PART OF OUR SYNDICATED MARKET INSIGHT SUBSCRIPTION SERVICE. IT SHALL BE OWNED IN ITS ENTIRETY BY 451 RESEARCH, LLC. THIS REPORT IS SOLELY INTENDED FOR USE BY THE RECIPIENT AND MAY NOT BE REPRODUCED OR RE-POSTED, IN WHOLE OR IN PART, BY THE RE- CIPIENT WITHOUT EXPRESS PERMISSION FROM 451 RESEARCH. ©2018 451 Research, LLC | WWW.451RESEARCH.COM 451 RESEARCH REPRINT Establishing itself as an up-and-coming player in the hybrid processing space, Esgyn has rolled out an updated version of its EsgynDB database, which is based on Apache Trafodion. The company is also making an active push into the cloud with a managed cloud service called Esgyn Strato, which is ex- pected to be generally available in November on AWS and Azure. THE 451 TAKE With hybrid workloads on the rise, Esgyn is in a good position to ride the current wave. The startup’s core technology of Apache Trafodion hearkens back nearly 30 years to technology developed at Tan- dem and later refined at Hewlett-Packard. As such, the company’s core technology rests on a solid foundation with a proven history.

  • Supplementary Material for Traditional Agricultural Practices and the Sex Ratio Today Alberto Alesina1,2, Paola Giuliano3,2,*, Nathan Nunn1,2
    Supplementary Material for Traditional agricultural practices and the sex ratio today Alberto Alesina1,2, Paola Giuliano3,2,*, Nathan Nunn1,2 1 Harvard University. 2 NBER. 3 UCLA. *Correspondence to: [email protected] The Supplementary Material provides details on the data sources and the robustness of the analysis for the results derived in the paper. Additional details on the Ethnographic Atlas The Ethnographic Atlas was constructed by George Peter Murdock. It contains ethnographic information for 1,265 ethnic groups worldwide. The period in which the information was collected varies by ethnicity, with the earliest observation dates coming from ethnicities in the Old World (where early written evidence is available) and the most recent information dating around the 20th century, for those parts of the world without a written history and directly observed by anthropologists. All societies are observed prior to industrialization. In total, 23 ethnicities are observed during the 17th century or earlier, 16 during the 18th century, 310 during the 19th century, 876 between 1900 and 1950, and 31 after 1950. For nine ethnicities, an exact year is not provided. The variable v39 classifies each ethnic group as being in one of the following three categories: (1) the plough was absent, (2) the plough existed at the time the group was observed, but it was not aboriginal, and (3) the plough was aboriginal, having existed prior to contact. Using this information, we construct an indicator variable that equals one if the plough was ever adopted during the pre-industrial period (whether aboriginal or not) and zero otherwise. Of the 1,156 ethnicities for which information exists, for 997 the plough was absent, for 141 the plough was adopted (and aboriginal), and for 18 it was adopted, but after European contact.

We will look at: ● Kernel Implementation details. ●what was added/changed in brief. ● User space interface. ● Some working examples. ● Usage of namespaces and cgroups in other projects. ● Is process virtualization indeed lightweight comparing to Os virtualization ? ●Comparing to VMWare/qemu/scaleMP or even to Xen/KVM. 3/121 http://ramirose.wix.com/ramirosen Namespaces ● Namespaces - lightweight process virtualization. – Isolation: Enable a process (or several processes) to have different views of the system than other processes. – 1992: “The Use of Name Spaces in Plan 9” – http://www.cs.bell-labs.com/sys/doc/names.html ● Rob Pike et al, ACM SIGOPS European Workshop 1992. – Much like Zones in Solaris. – No hypervisor layer (as in OS virtualization like KVM, Xen) – Only one system call was added (setns()) – Used in Checkpoint/Restart ● Developers: Eric W. biederman, Pavel Emelyanov, Al Viro, Cyrill Gorcunov, more. – 4/121 http://ramirose.wix.com/ramirosen Namespaces - contd There are currently 6 namespaces: ● mnt (mount points, filesystems) ● pid (processes) ● net (network stack) ● ipc (System V IPC) ● uts (hostname) ● user (UIDs) 5/121 http://ramirose.wix.com/ramirosen Namespaces - contd It was intended that there will be 10 namespaces: the following 4 namespaces are not implemented (yet): ● security namespace ● security keys namespace ● device namespace ● time namespace.

  • Magic Quadrant for Data Integration Tools
    20/08/2019 Gartner Reprint Licensed for Distribution Magic Quadrant for Data Integration Tools Published 1 August 2019 - ID G00369547 - 92 min read By Analysts Ehtisham Zaidi, Eric Thoo, Nick Heudecker The data integration tool market is resurging as new requirements for hybrid/intercloud integration, active metadata and augmented data management force a rethink of existing practices. This assessment of 16 vendors will help data and analytics leaders make the best choice for their organization. Strategic Planning Assumptions By 2021, more than 80% of organizations will use more than one data delivery style to execute their data integration use cases. By 2022, organizations utilizing active metadata to dynamically connect, optimize and automate data integration processes will reduce time to data delivery by 30%. By 2022, manual data integration tasks (including recognition of performance and optimization issues across multiple environments) will be reduced by 45% through the addition of ML and automated service-level management. By 2023, improved location-agnostic semantics in data integration tools will reduce design, deployment and administrative costs by 40%. Market Definition/Description The discipline of data integration comprises the architectural techniques, practices and tools that ingest, transform, combine and provision data across the spectrum of data types. This integration takes place in the enterprise and beyond — across partners as well as third-party data sources and use cases — to meet the data consumption requirements of all applications and business processes. This is inclusive of any technology that supports data integration requirements regardless of current market nomenclature (e.g., data ingestion, data transformation, data replication, messaging, data synchronization, data virtualization, stream data integration and many more).
