NewsBits: Fresh Elasticsearch, WebGL Graphs and Redis toolsPublished
Welcome to NewsBits where you'll find the database, OS, security, and developer news from around the net for the week ending July 27th.
- Elasticsearch gets a "trial security" update.
- See your graphs in WebGL.
- Redis tools to work with RDB files.
- Updated Ubuntu LTS edition lands.
- For BSD afficiandos, NetBSD 8.0 has arrived.
- The Spectre vulnerability, now on the network.
- Elixir gets better, metadata enhanced, docs.
- Bug fix release for GCC.
- And finally, the end of an era in Japan means...
Now, those bits in full:
Although not formally announced, Elasticsearch 6.3.2 is now available. The release notes note a number of bug fixes, though its release may have been pre-empted by the need to fix a trial license upgrade bug which was disabling X-Pack security in Elastic's proprietary extensions.
Graphs and WebGL
We've all seen two dimensional renderings of graph databases, but in this article from Neo4j they show how to use WebGL to create 3D force graphs which are using 3d-force-graph. The library is database agnostic, so the techniques should work with any graph dataset.
redis-cli-tool is actually a new collection of tools for working with Redis rdb files and Redis either to extract, merge or migrate data from them. It's an interesting option with a plethora of options.
Ubuntu 18.04.1 LTS - If you're running the latest Ubuntu 18.04 LTS on your servers, be aware that Ubuntu 18.04.1 LTS is now available. The update's change summary lists a large number of upgrade process fixes, paving the way for smoother future updates. There's also point updates for OpenStack packages, kernel updates and bug fixes (including microcode fixes for Spectre2 on some Intel processors) and much more. All these fixes and updates should have already rolled out to regularly updated systems; the 18.04.1 release gives admins new images to start from with the changes already rolled in. The new ISOs are available to download from Canonical's servers.
NetBSD 8.0 - The NetBSD project has released NetBSD 8.0, complete with a new USB stack with USB 3 support, Spectre and Meltdown mitigations, CAN bus support and many updates of the various packages used. If you use NetBSD, the developers urge you to upgrade. The project has also reworked it's future support plans reducing the number of small forks in future for better long term support.
Spectre on the network
NetSpectre - At 15 bits of data an hour leaked, the latest variant of Spectre attacks is not the fastest. NetSpectre does though work remotely over the network without using a covert channel - and adding a covert channel bumps that rate up to a blistering 60 bits an hour. NetSpectre is an attack that is probably of interest to owners of very high value targets but it shows the genie of speculation and caches in modern CPUs is completely out the bottle. Read the paper(pdf) or read more on Ars technica.
Elixir 1.7 - Elixir, the dynamic/functional language built on the Erlang VM, has seen an update in the form of Elixir 1.7. Headline feature on this release is that the documentation for Elixir is now compatible with EEP48, an Erlang wide specification for compatible documentation metadata. That means also that the IEx shell can access that metadata and that Elixir documentation tools will use the EEP48 features to mark deprecations and versions better. Also added: Erlang/OTP 21 logger support and
__STACKTRACE__ handling along with improved ExUnit testing.
GCC 8.2 - The GNU Compiler Collection has a fresh bug update. Most of the listed changes address regressions in the various compilers behaviors.
Japan's own Y2K is approaching in the form of the planned abdication of the Japanese Emperor, Akihito, in April 2019. The problem? The Japanese calendar counts up from the coronation of the emperor marking the start of a new era. This hits the tech business in particular, including the next revision of Unicode, tax systems and diary makers.
