[NEWS] Open Sourcing Cloudant Search {see thread) and Cloudant Search is Open Source now! (see thread)

IBM Cloudant announced to be “Open-Sourcing CouchDB Search Integration with Lucene”! This means, Cloudant open sourced the Search Stack that is powering the Cloudant Search features, which “consists of two repositories, Dreyfus, written in Erlang and Clouseau as a Scalang project that uses Lucene. Dreyfus is compatible with the new clustering features of CouchDB and makes use of them. It establishes links between the VMs/nodes to get the results from the shards before merging them as the final result which is returned to the user. For details how it works under the hood see this document.”

The CouchDB community happily discusses, how to optionally integrate the two projects as part of the ASF.

[2.0] Replication Issues (see thread)

While trying to upgrade a database from 1.6.1 to 2.0.0/master/0c579b98 and Jan listed a number of issues. Help is greatly appreciated with those! (See list of issues in the thread). Replication is running on 2.0, pulling from 1.6.1 over the EC2 internal ip address. One issue has already been fixed.

Hide all _all_docs and _changes (see thread)

A user wants to disable the ‘_all_docs’ feature in general, or ‘_all_docs’/ ‘and _changes’ for only specific databases, to prevent a user from seeing a list of all documents, the latter of which is not possible. It was advised to ensure that only wanted parts of the API are available and to consider using a reverse proxy, like nginx.

Using _active_tasks to track continuous replication status (see thread)

A user tries to find a way to know whether a document has been effectively replicated (in continuous mode) to a remote CouchDB, with a minimum of network requests. Two approaches have been suggested, one of which is getting the document ‘local_seq’ on the source side and watch the replication status on ‘_active_tasks’ until the completed sequence, ‘checkpointed_source_seq’, is equal to the document’s one.

Basic user cannot acces _users view (see thread)

Here a user wants to know how to allow ‘basic users’ in CouchDB 1.4.0 (without user or admin roles defined) to access ‘_users’ design document in order to call some view (when users have a ‘group’-property) and only get users of their group. It was indicated to take the security section about User’s Public Information into concern.

Updating lost user passwords (see thread)

The user@ mailing list was asked, if it is possible to make a user privileged (not an admin), to permit make changes to other ‘_user documents’, such as password changes. The answer to this is, that it is currently not possible, as only admins can edit other user’s ‘_users docs’.

Time to relax!

  • “Just recently I spent a week doing support work for an application while my coworker was on vacation, reminding me yet again how much I learn from it. Since this was the first time I’d been involved with the app, I learned about the ways our users were getting tripped up, and saw pitfalls which I may never have thought about otherwise.” – Developing Empathy
  • “Much like what is said about including accessibility in your design, it doesn’t have to be extra work to make your culture sober-friendly, and it will improve everyone’s experience as a byproduct. Hold events at places other than bars – consider venues that don’t serve alcohol… When you focus on alcohol as the main activity, such as meeting in a bar, it becomes a barrier to participation for those hoping to refrain from alcohol.” – The UX of Alcohol Abuse: Reflections on a Year of Sobriety
  • “… the requirement to use a real name violates the rights, enshrined in German law, to use a pseudonym, while requests for digital copies of an official photo ID also contradict the passport and ID card law. In addition, he said that “the unauthorised modification of the pseudonym … blatantly violated the right to informational self-determination and constitutes a deliberate infringement of the Data Protection Act”.” – Germany fights Facebook over real names policy
  • “Organizations interested in hiring more diverse candidates need not lower their hiring bar; instead, they should raise the bar and create an interview process that takes a more rigorous, research-based approach to hiring.” – Want to Hire More Diverse People? Raise Your Bar.
  • “hen we meet people who are deaf, we can’t see what is physically wrong with them, but we believe them when they say they can’t hear us. Why don’t we believe people with other disabilities?” – Human Operating Systems
  • “As a Black female CS major at Stanford, I hate walking around the halls of the Gates Computer Science Building.” – No, I Am Not Lost, A Black woman’s experience in the Stanford Computer Science Major
  • “There was always going to be a cis white woman on stage (me), which meant that if I didn’t pay attention, these “all women” panels might have reinforced other hierarchies. In the initial list of speakers I wanted to invite, I noticed that a significant number of them speak openly about their queerness, trans identity, or race.” – How I Organized a Series of Six Panels on Technology with Only Women Speaking
