Incubator PMC report for May 2019

The Apache Incubator is the entry path into the ASF for projects and
codebases wishing to become part of the Foundation's efforts.

There are presently 50 podlings incubating. During the month of April,
podlings executed 10 distinct releases. We added two new IPMC members
and no IPMC members retired.

We have no new podlings this month. Three projects graduated last month 
namely PLC4X, SkyWalking and Netbeans and several other podlings are 
heading towards graduation in the next few months.

One of the podlings that failed to report last month, Milagro failed to
report again this month and the IPMC will discuss what to do. This is the 
not first time this project has failed to report and it may not have a
working PPMC.

Two podlings Milagro and Toree have not submitted reports and will be asked
to report next month.

There were two IP clearances.

The new Podling clutch page is working well and documentation has been 
created clearly explains what information is collected from where.

The incubator is providing a new service to podlings to provide feedback on
releases. So far no podlings have taken up this service. 

Mentors are being actively encouraged to vote on their podling releases so
that the VOTEs show up on the general@ list with 3 +1 IPMC votes. While a 
couple of podlings have managed to do this, most still need extra votes by 
IPMC members outside their projects. The IPMC will need to look further
into this.

In a couple of cases, podlings canceled vote too early and were encouraged
to continue voting.

Incubator wiki is being deprecated, and it's been migrated to confluence. 
Some of the pages were missed in the transfer and infra are looking into 
why.

The new wiki space has been reorganised and the pages categorised for easier
navigation. A few minor issues have been encountered e.g. confluence 
ignoring formatting but have been addressed. A few people have had permission
issues and because of this move mentor sign-off is a little lower than normal. 

The reorganisation and cleanup of incubator web pages started last month 
continues on.

brpc

brpc is an industrial-grade RPC framework for building reliable and 
high-performance services.

brpc has been incubating since 2018-11-13.

Three most important issues to address in the move towards graduation:
  1. We begin to prepare an apache release, including prepare for unified 
  License/Copyright, clean dependencies.
  2. We depend on npsr’ time, it is MPL/LGPL license, we need to find 
  another lib for it.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware 
of?

  No

How has the community developed since the last report?

  Added two potential committers, they are huwenwei and wangweibing ,
  they will participate in the work of first apache release , and take some 
  tasks already.  .

How has the project developed since the last report?

  There are many bugfix into the trunk.

How would you assess the podling's maturity?

  Still in early stage

DataSketches

DataSketches is an open source, high-performance library of stochastic
streaming algorithms commonly called "sketches" in the data sciences. 
Sketches
are small, stateful programs that process massive data as a stream and can
provide approximate answers, with mathematical guarantees, to 
computationally
difficult queries orders-of-magnitude faster than traditional, exact 
methods.

DataSketches has been incubating since 2019-03-30.

Three most important unfinished issues to address before graduating:

  1. Finish IP Assignments
  2. Code Migration
  3. Perform a Release

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  No

How has the community developed since the last report?

  We have the key committers signed up. We are all learning how
  to navigate in the Apache environment and how to find things.

How has the project developed since the last report?

  This is our first report.

ECharts

ECharts is a charting and data visualization library written in JavaScript.

ECharts has been incubating since 2018-01-18.

Three most important unfinished issues to address before graduating:

  1. Apache domain name should be used for the Website. 
  echartsjs.com and echarts.baidu.com should redirect to 
  echarts.apache.org. 
  Currently they are not redirecting due to slow loading time in China. 
  We are working on with a CDN to improve the loading time in China.
  2. Website Analytics information should be accessed by PPMC members.
  We are going to create an Analytics account that can be accessed by PPMC 
  members.
  3. Develop more committers from the community.
  Currently there are some contributors in the community that have 
  contributed continuously and should be considered as new committers.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
  We haven't come to a conclusion whether we could use Baidu Tongji in the 
  Website, 
  which is a product quiet similar to Google Analytics.
  We've consulted John Kinsella <jlkinsel@gmail.com> as our mentor 
  suggested, but got no reply. See 
  https://lists.apache.org/thread.html/efa62d1ace0cc27f7ee4e47df94c346e863b6419f1d1e3ea6fe32c10@%3Cdev.echarts.apache.org%3E
  My suggestion is to use both Baidu Tongji and Google Analytics. The 
  reason is that Baitu Tongji has only Chinese UI, while Google Analytics
  may have the potential of losing some data in China since many Google products
  are not accessible in China.
  If IPMC and ASF Board are OK with it, we will start a vote for the plan.

How has the community developed since the last report?
  We have announced our first new committer from the community.
  More people come to contribute in the community, in the forms of code 
  changes, document mending, and so on.

How has the project developed since the last report?
  We released v4.2.1.

  Justin Mclean: Is Baidu analytics compliant with the GDPR (EU General Data
  Protection Regulation)? 
  You might also want to see MXNet's report about needing an ICP filing when

IPMC/Shepherd notes:

--------------------
Edgent

Apache Edgent is a programming SDK and micro-kernel style runtime
that can be embedded in gateways and small footprint edge devices enabling
local, real-time, analytics on the continuous streams of data coming
from equipment, vehicles, systems, appliances, devices and sensors of
all kinds (for example, Raspberry Pis or smart phones). Working in
conjunction with centralized analytic systems, Apache Edgent provides
efficient and timely analytics across the whole IoT ecosystem: from the
center to the edge.

Edgent has been incubating since 2016-02-29.

Three most important issues to address in the move towards graduation:

  1. Re-creating a working community
  2. Re-populating the PPMC
  3. Replenishing the group of mentors

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  For the past months, there has been very few activity in the project
  There have been a hand full of Emails from external peoples in the
  last 3 months but the activity in the project has been solely by me
  (Julian) and Christofer Dutz writing emails without getting any form
  of response from the rest of the committers, PPMCs or mentors

  Julian held a Talk on the conference buildingiot 2019 with very positive
  response and we have an Edgent Meetup on May, 6. Where we hope to see 
  some new faces.

  The main problem we have is that the only active people in the project
  came in Late and are not that firm with the codebase. Currently, we
  have a codebase for which we have a detailed understanding of the build,
  but almost none of the code itself. Furthermore, there has been a lot of
  activity in other projects and generally edge processing has developed
  further in the recent years.
  Thus, there is some discussion going on about the core or the aim of the 
  project to keep its significance and uniqueness.

How has the community developed since the last report?

  * Total, we have 82 subscribers to our mailing list, an increase of 5
  since the last report.
  * There has been one questions asked by users and little
  discussions about these issues on the list
  * On April, 4th, Julian Feinauer has Talked about Edgent on the building
  iot 2019
  * On May, 6th, a Edgent Meetup is planned in Frankfurt

How has the project developed since the last report?

  * According to JIRA, 0 new issue were added and none were resolved in
  the last 90 days

How would you assess the podling's maturity?

  After the withdrawal of most of the active committers and PPCM members
  currently a new committer, PPMC and mentor-base has to be built.
  Currently we try to re-gain the focus of edgent to
  Start to rebuild the community and resume development.

  I just double checked, but it seems our mentors are not existent
  there had been one or two issues where feedback was explicitly
  asked for, but both the PPMC as well as all mentors remained silent.
  Except Justin mentioning the absence of mentors. Christofer Dutz
  joined as new Mentor and is active in the project.

MXNet

A Flexible and Efficient Library for Deep Learning

MXNet has been incubating since 2017-01-23.

Three most important unfinished issues to address before graduating:

  1. Increase diversity in contributors, committers, and PMC members — NEAR 
  COMPLETION.
  2. Identify remaining ICLAs or SGAs that need signing – NEAR COMPLETION.
  3. Revisit Apache Maturity Model Assessment — TODO

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
  1. Community reached consensus on Gluon branding. In the context of the 
  Gluon API in MXNet, it would be mentioned as MXNet Gluon. 
  https://lists.apache.org/thread.html/af7dcb430e2cedf23d1531e79877e8bf2b40ec392e40853a2d7015da@%3Cdev.mxnet.apache.org%3E
  2. Community addressed the IP/licensing issues discovered during previous 
  releases. Updated status can be found here: 
  https://cwiki.apache.org/confluence/display/MXNET/MXNet+Source+Licenses 
  3. MXNet has significant user presence in China that are worth optimizing 
  for in terms of infrastructure. Setting up CDN in China requires ICP 
  filing.

PageSpeed

PageSpeed represents a series of open source technologies to help
make the web faster by rewriting web pages to reduce latency and
bandwidth.

PageSpeed has been incubating since 2017-09-30.

Three most important unfinished issues to address before graduating:

  1. Get the project site in order
  2. Start releasing
  3. Engage more active developers, expanding the community

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

How has the community developed since the last report?

  The number of active developers is low, we are still working
  to follow up on the recommendation to create a release.

How has the project developed since the last report?

  - A first draft-release is being manually checked for policy compliance. 
  We expect
  to be able to raise a thread on general soon to discuss/vote.
  - There has been some discussion how to get the project site in-order, 
  and there's
  a plan for that now (transfer modpagespeed.com to the AFS, duplicate 
  contents to
  pagespeed.incubator.apache.org).

  Comments: The podling is likely in need of more mentors who can pay 
  closer attention if they want to survive (an additional mentor was added 
  but has yet to participate in the podling).  I'm not sure how much of a 
  community is here to be honest, while development works well (slow, but 
  well) not seeing much consumer interaction.

Training

The Training project aims to develop resources which can be used for 
training purposes in various media formats, languages and for various 
Apache and non-Apache target projects. 

Training has been incubating since 2019-02-21.

Three most important issues to address in the move towards graduation:

  1. Agree upon underlying technology stack and architecture for training 
  content
  2. Develop first training topic contents
  3. Set up our contribution process

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  - no critical issues at this point in time

How has the community developed since the last report?

  - The project has been set up recently, so there is an initial 
  activation/development towards a community.
  - The dev mailing list is active. The total number of posts in March was 
  160 and in April 140
  - Total number of subscribers is 32 (25 in March)

How has the project developed since the last report?

  - The scope of the project deliverables and core procedures are still 
  under discussion (e.g. what makes a release?)
  - We have had our first few commits. They were for infrastructure (e.g. 
  website) and repository structure
  - We have been approached by a few more people wanting to donate content 
  and we hope to be able to accept it soon
  - We actually have the first issue for an actual content donation (Apache 
  Way, ZooKeeper and Git) and hope to have it included soon, the first ones 
  will probably be slow while we work on processes and best practices

  2. Have the works of the project comply with legal requirements of the 
  ASF;
  3. Consistently releasing products;

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be

  Currently there are no issues that require the involvement of either the
  Incubator PMC or the ASF board.

How has the community developed since the last report?

  As this is the first full month of the project incubating the development
  of the community has been low.

  The project started out with onboarding all parties showing interest
  at the pre-incubation discussions in general@incubator.a.o.

  The project consists of a healthy number of mentors and committers/PPMC
  Members.

How has the project developed since the last report?

  All required INFRA services have been put in play to have the community
  collaborate.

  The project is working on getting more body to the whole set of 
  information pages (website, wiki, etc.)

  The project is working on getting its first release product vetted and
  released, and is also working on getting the Incubator clutch details
  up to date.
