Welcome to NewsBits where you'll find the database, cloud, and developer news from around the net for the week ending December 15th 2017
- Elasticsearch 6.1 splits the index.
- GA comes for Apache Hadoop 3.0.
- Machine learning instead of database indexes?
- pgBackRest gets encrypted.
- The return of a classic TLS security hole.
- W3C recommend their HTML 5.2.
- The final JSON specification?
- VS Code gets refreshed.
- And finally, some Rusty CHIPs...
And now, those NewsBits in full:
Elasticsearch - Version 6.1 of Elasticsearch is now available from Elastic. New features include an index splitting API and a new pageable composite aggregation function so you can return all the results from a query and work your way through them page by page.
The biggest updates though seem to be for Kibana - the 6.1 release has new input controls for dashboards, a homepage, cross-cluster search monitoring support, new visualizations, labels for piecharts and more.
Apache Hadoop - Less a singular project and more a huge ecosystem, Hadoop is found in many big data projects, and now it's GA time for Hadoop 3.0.0. The changes include a bump for required Java version (now Java 8), HDFS erasure coding to save space, a rewrite for all Hadoops shell scripting and a preview of a new more scalable and reliable YARN Timeline.
Indexes as models - In The Case for Learned Index Structures, the MIT and Google authors put forward the concept of using models instead of indexes to locate stored data. It argues that real-world access patterns could make the learned model more efficient than the general purpose B-tree index and then delves into some experimentation around that idea.
The early results are promising - expect plenty of research into this in the future as machine learning hardware becomes more integrated into general purpose computing.
pgBackRest - pgBackRest, the backup utility for PostgreSQL, has a new release out. The new version 1.26 adds the ability to encrypt your backup repositories and comes at the end of a year of solid improvements such as S3 bucket support, multi-threaded asynchronous archiving and backup standby support.
TLS ROBOT - It's an old flaw with a new twist and a website and logo - say hello to the ROBOT (Return of Bleichenbacher's Oracle Threat). It turns out that an old vulnerability from 1998 still has legs partly because the countermeasures in subsequent versions of TLS were "incredibly complex".
It's no Heartbleed because to exploit it you need to do hundreds of thousands of connections to reveal data but it is an important issue. The final question on the web page shows how hard it was to classify:
W3C HTML 5.2 - Here's the latest version of the W3C's HTML 5.2, now a W3C recommendation. The changes include additions like a new
JSON - "I think this is the last specification of JSON that anyone will ever publish" says Tim Bray in a blog post about RFC 8259. Bray edited the RFC which basically takes current JSON specifications and says JSON must be encoded in UTF-8 (with an exception if you are in a closed ecosystem). Developers should note, if you're building a REST API or similar, Bray recommends RFC7493 instead - same syntax but more rules to avoid "legal-but-dumbass things".
VS Code - The latest update to Microsoft's VS Code has arrived. Amongst the improved performance, diagnostics, Intellisense and tab layout enhancements, our favourite addition is that you can now pipe output from the command line straight into the editor.
And finally, how about a story that combines the latest in WebAssembly and Rust with the old school charm of the CHIP-8 interpreter and ends up running ROMs in your browser.
