What happened to the Teradata Kylo product? - teradata

GitHub activity is just empty last month, at least
download links for the latest release 0.10.1 (March, 2019) lead to nowhere
same thing for VirtualBox images - AWS S3 bucket does not exist
My questions are:
Is the project dead?
Is there any open source active project which supersedes Kylo?

According to the post pinned at the top of the Kylo community Google Group, Teradata decided to discontinue Kylo development and support in early 2019 and no new sponsor stepped forward to take over the project

Here is the message posted in the Kylo Google Group:

Teradata made the decision to discontinue Kylo in early 2019. Teradata
had been the sole sponsor of the open-source project and offered paid
corporate training, consulting services, and enterprise subscriptions
for support. The team was unable to immediately secure a new sponsor
and devs have moved on to other projects.
The last official release of Kylo was March 2019. The downloads of
the RPM and sandbox are no longer available but you may still build
the RPM (or TAR) from maven.

Which Distribution CDH Vs HDP

I happened to work on CDH longtime back ( around 1 year) and am planning to start again.Now we had CDH , HDP and Hortonwork acquired by Cloudera .
Is HDP being developed actively ? Or Is CDH being developed actively ?
Which distribution I should get started with ?
Cloudera (the company behind CDH) and Hortonworks (the company behind HDP) have merged. They now are called Cloudera.
After the merger a new distribution was released, called the Cloudera Data Platform, or CDP in short.
Though both older platforms will still exist for a short while, all new users should go for CDP. This is the platform that is seeing all development focus.
Note that the situation may be more nuanced if your company is already a heavy user of either HDP/CDH but even in those cases the formal recommendation is still to go to CDP as soon as possible.
Full disclosure: I am an employee of Cloudera (formerly Hortonworks), the company behind CDP as well as HDP and CDH.

What is the status of RxAndroidBle and RxJava3?

RxAndroidBle is a great piece of software and has reduced development time for Ble projects and has increased stability and readability significantly.
I just want to ask, what the status is of the rxjava3 branch of RxAndroidBle?
It says it is a test branch and stale at this moment.
So is it not recommended to take the rxjava3 branch for production applications?
I wonder if there are future plans to concentrate on rxjava3, since on the RxJava page it says:
The 2.x version is in maintenance mode and will be supported only through bugfixes until February 28, 2021.
Greetings from t4rj4n
RxAndroidBle added support for RxJava3 in version 1.15.0 on 13. June 2022. All releases after that have had support for both RxJava2 and RxJava3.
You can find the releases on the Releases page on GitHub.

Is Tinkerpop3 production ready?

I am currently using Tinkerpop 2.5 in my application to represent a graph in-memory and gremlin to query it. This application will go into production at end of July 2015. I am confused if I should use 2.5 or 3. Currently Tinkerpop 3.0.0 is in M7 release. I don't see any information on the GA release schedule.
At this time, TinkerPop 2.x is basically in maintenance-mode only (i.e. we've generally frozen development short of major bug fixes). All effort is focused on TP3 and getting it to GA. GA has been somewhat delayed as TinkerPop moves to its new home as an Apache project: http://tinkerpop.incubator.apache.org/
Unfortunately, we can't provide much certainty for when GA will be available, so this leaves people starting a project and trying to make the choice between TP2 and TP3 a bit difficult. I can say that if you use TP2, it has good stability and a very wide number of vendors who support it. If you use TP3, expect some turmoil in the API on the way to GA and keep in mind that, at this time, you don't have a lot of vendor support for the interfaces though many vendors are committed to having TP3 implementations when GA is in place: http://www.tinkerpop.com/docs/3.0.0-SNAPSHOT/#_graph_vendors
UPDATE: TinkerPop 3.x was released into GA in July 2015 and can now be considered production-ready. There have been multiple releases since that initial one. Latest developments can be found on the project home page: http://tinkerpop.apache.org/

Neo4j replication alternative to Neo4j Enterprise edition?

It seems Neo4J High Availability is only available for the Enterprise edition which is paid- is there another alternative to achieve replication without that module? (i.e. without cost). Thanks for any help!
Update:
This answer has changed. Neo4j is now open core, so the Enterprise code is no longer dual-licensed - only the commercial license option remains.
You can find more details here: https://neo4j.com/open-core-and-neo4j/
Original Answer:
Enterprise is available as quid-pro-quo - if you put your code out under an open source license, then you get access to the open source Neo4j Enterprise free of charge. However, if you are closed source, Neo Tech charges a license fee. This fee is determined by your needs and your ability to pay - if you are a small outfit with no venture capital, it's still free, and then the licensing cost increases as your ability to pay back to the development of Neo4j increases.
If your application is open-source as you mention, then you are free to use Neo4j Enterprise without paying for it, simply download it at neo4j.org.
Actually Neo4j Enterprise is free under the open source AGPLv3 license.
Neo4j Inc can't modify the terms and still call it AGPL.
If you use Neo4j Enterprise as a server (like most people do) and communicate with it via its REST API or any of the official BOLT drivers then you never trigger AGPL's copyleft requirements.
In other words - the software that connects to it does not have to be open sourced.
You can download Neo4j Enterprise open source licensed binaries up to version 3.2.x from dist.neo4.org. The links for the windows and unix packages are below. (Replace the version number for specific versions)
http://dist.neo4j.org/neo4j-enterprise-3.2.8-windows.zip
http://dist.neo4j.org/neo4j-enterprise-3.2.8-unix.tar.gz
If you want Neo4j Enterprise 3.3.0 and on under it's free open source license, then you can build them from source like we do for our US government clients, or just grab them from our free distribution site.
Check out the blog post if you want to understand why this has happened.

Does the Mobile Device Browsing File live on?

According to http://mdbf.codeplex.com/:
"Due to the organizational restructuring of the team that developed and supported the Mobile Device Browser file, we will no longer have the resources to support and update this CodePlex project. The team will be providing two more releases – one on the 27th July 2010 and the final release on the 24th August 2010.
We would like to thank everyone who used our product over the past year and a half. We would also like to thank everyone who contributed to the discussions and raised issues on our data."
Does this project live on someplace else or is there an equivelent project?
51degrees claims to have a replacement, but it isn't made in the same way (via .browser definition files).
MDBF is still hosted on codeplex though - they reopened it by demand, but there isn't any promises of any updates that could occur.
