Senate GMail Attack – eXist-db 5.0.0 RC 4 Release – Coincidence?

Filed under: Cybersecurity,eXist,Government,XML,XML Database,XQuery — Patrick Durusau @ 6:16 pm

First I see Senators’ Gmail accounts targeted by foreign hackers from today that reads in part:

The personal Gmail accounts of an unspecified number of US senators and Senate staff have been targeted by foreign government hackers, a Google spokesperson confirmed to CNN on Thursday.
…

then I see in my Twitter feed:

[eXist-db] v5.0.0-RC4 – September 21, 2018.

The campaign season has been devoid of any Clinton-like email leaks, which is both disappointing and a little surprising.

It worked so well last time, taking no news office gossip and by timed release, make back-biting chatter into widely reported news.

You should grab a copy of eXist-db v.5.0.0-RC4 or the current stable version. Practicing now will keep you in shape for any flood of congressional emails.

eXistDB is NOT in league with any hackers anywhere.

I like feeding the paranoid delusions of the IC with groundless gossip. They will write it down, talk about it, do research, all the while they are not out harming US citizens and/or hopefully citizens of any other countries.

eXist-db 5.0.0 RC 3 [Prepping for Assange Data Tsunami]

Filed under: .Net,eXist,XML,XML Database,XQuery — Patrick Durusau @ 10:40 am

eXist-db 5.0.0 RC 3

One new feature and several bugs fixes over RC 2, but thought I should mention it for Assange Data Tsunami preppers.

I have deliberately avoided contact with any such preppers but you can read my advice at: username: 4julian password: $etJulianFree!2Day.

The gist is that sysadmins should, with appropriate cautions, create accounts with “username: 4julian password: $etJulianFree!2Day,” in the event that Julian Assange is taken into custory (a likely event).

If one truth teller (no Wikileaks release has ever been proven false or modified) disturbs the world, creating a tsunami of secret, classified, restricted, proprietary data, may shock it to its senses.

Start prepping for the Assange Data Tsunami today!

PS: Yes, there are a variety of social media events, broadcasts, etc. being planned. Wish them all well but governments respond to bleeding more than pleading. In this case, bleeding data seems appropriate.

eXist-db – First Upgrade for 2018

Filed under: eXist,XML,XML Database,XQuery — Patrick Durusau @ 2:06 pm

I usually update from notices of a new version and so rarely visit the eXist-db homepage. My loss.

There’s a cool homepage image. With links to documentation, community, references, but not overwhelmingly so.

Kudos! Oh, the upgrade:

eXist-db v3.6.1 – January 03, 2018

From the release notes:

eXist-db v3.6.1 has just been released. This is a hotfix release, which contains bug fixes for several important issues discovered since eXist-db v3.6.0.

We recommend that all users of eXist 3.6.0 should upgrade to eXist 3.6.1.

Bug fixes

  • Fixed issue where the package manager wrote non-well-formed XML that caused problems during backup/restore. #1620
  • Fixed namespace prefix for attributes and namespace nodes.
  • Made sure the localName of a in memory element is correctly obtained under various namespace declaration conditions
  • Fix for NPE in org.exist.xquery.functions.fn.FunId #1642
  • Several atomic comparisons raise wrong error code #1638
  • General comparison to empty sequence sometimes raises an error #1639

Backwards Compatibility

  • eXist-db v3.6.1 is backwards binary-compatible as far as v3.0, but not with earlier versions. Users upgrading from previous versions should perform a full backup and restore to migrate their data.

XQuery Working Group (Vanderbilt)

Filed under: eXist,XML,XQuery — Patrick Durusau @ 1:54 pm

XQuery Working Group – Learn XQuery in the Company of Digital Humanists and Digital Scientists

From the webpage:

We meet from 3:00 to 4:30 p.m. on most Fridays in 800FA of the Central Library. Newcomers are always welcome! Check the schedule below for details about topics. Also see our Github repository for code samples. Contact Cliff Anderson with any questions or see the FAQs below.

Good thing we are all mindful of the distinction W3C XML Query Working Group and XQuery Working Group (Vanderbilt).

Otherwise, you might need a topic map to sort out casual references. 😉

Even if you can’t attend meetings in person, support this project by Cliff Anderson.

eXist: XQuery FLWOR Expression Updates

Filed under: eXist,XQuery — Patrick Durusau @ 8:52 am

Fixes for FLWOR expressions #763

From the webpage:

This is a major update to FLWOR processing in eXist to align it with the 3.0/3.1 specification. The “for”, “let”, “where”, “order by” and “group by” clauses are now implemented as separate classes (instead of being attached to a main “for” or “let”), and may thus appear in any place the spec allows. A FLWOR expression may have multiple “order by”, “group by” or “where” clauses. The previous implementation was too restrictive, allowing those clauses only in specific positions.

The “group by” clause, which was added back in 2007 and has been updated a few times since then, was completely rewritten and does now also support collations. The “allowing empty” spec within a “for” is now respected.

You need the nightly build version to benefit from these latest changes. (As of August 28, 2015. Eventually the changes will make it into a release candidate and then into a stable version.)

Currently available versions include:

Stable Release, version 2.2

Release Candidate, version 3.0 RC 1 (not recommended for production)

Nightly Builds, Use at your own risk

I first saw this in a tweet by Jonathan Robie.

eXist RC 1.4.1

Filed under: eXist,XML Database — Patrick Durusau @ 7:55 pm

eXist RC 1.4.1

I saw a post on a mailing list from Adam Retter with the following news:

I would just like to let you all know that the Release Candidate for eXist-db 1.4.1 is out, this is the culmination of two years of hard work. We take our releases very seriously!

eXist-db is all about XML, indexing and querying. We provide various indexes including full-text indexing of structured, semi-structured and un-structured content. Our unit of storage is the Document, XML or Binary. We can also extract and make searchable content from Binary Documents.

Not only is eXist-db an OpenSource XML Native Database, its also a fully fledged web application platform for XRX applications, so don’t let the ‘-db’ bit fool you.

Had not meant to be neglecting the XML databases. You are going to encounter them in a number of contexts, either as storing data you need or as repositories you address from within a topic map.
