Please help me .
Thanks in advance.
Titan as product is dead about 2 weeks ago. DataStax (Cassandra company) hired the Titan team, but not the product. They preferred to abandon Titan. Here the official announcement:
http://www.zdnet.com/article/datastax-snaps-up-aurelius-and-its-titan-team-to-build-new-graph-database/
"We're not going to do an integration. The play here is we'll take
everything that's been done on Titan as inspiration, and maybe some of
the Titan project will make it into DSE Graph," DataStax engineering
VP Martin Van Ryswyk said... But we're really going to build something
new because we're going to be able now to take advantage of Cassandra
specifically and DSE features specifically. It will be an engineering
effort to build a new product. We will not be supporting or
integrating Titan as a product into our portfolio."
And this is the official announcement in Titan group:
"However, there is also some sadness in this announcement. As we
transition to DataStax, we will find little time to contribute toTitan
and interact with the Titan community. We will miss that and hope that
it will be carried forward."
Now, some users was very pissed off about this news. Read this:
"Not even that. They pulled the plug without a stable product, no
prior notice and not caring about the companies that used a buggy
system that broke compatibility every time just because a version 1.0
was promised."
(source: https://groups.google.com/d/msg/aureliusgraphs/WtU6om8CtqI/Q1_AIFRA4mkJ)
So after few days of flame in the group, Titan team said "Ok, Titan is alive", but this has been the reaction on Hacker News:
https://news.ycombinator.com/item?id=9025798
I'm not talking about Titan vs OrientDB from technical perspective (I'm the OrientDB author, so it would be unbiased), but I'm just pointing here that creating a new project based on a dead product seems a not so good idea. So you can go with OrientDB or wait for the new Cassandra DSE (Commercial only?) with graph features "inspired" to Titan.
You could also use spring-data-gremlin and see for yourself which database works best for you. It is a Tinkerpop blueprints Spring-Data abstraction allowing you to switch to potentially any graph database that implements the blueprints API - which both OrientDB and TitanDB do, and the project already includes those databases.
Note: spring-data-gremlin is a work in progress and may not yet fit all your requirements, but we'll get there.
Neo4J has native spring-data support.
http://projects.spring.io/spring-data-neo4j/
You can also use Blueprints (https://github.com/tinkerpop/blueprints/wiki), which allows you to switch backend database easily.

I am learning and analyzing the difference between eCommerce platforms like SAP Hybris, Salesforce, WCS, ATG and Magento etc.
What are the key parameters while you zero down to choose a product? And which is the best in the market at present?
This is a broad question that doesn't have a best answer. You could use Gartner to help you decide: https://www.gartner.com/reviews/market/digital-commerce
Personally, I would consider things like:
Cost: Do you want a free platform or a paid one? Some features (or support) may not be available in free platforms. Or, a paid platform may be too expensive for a small company.
Existing landscape: Are you building from scratch without dependencies on other systems, or do you need to consider existing systems (e.g. ERP) in the enterprise? Your customer may already have a SAP system and have a good relationship with them. So, they may want to use SAP Commerce Cloud, rather than Oracle Commerce Cloud
Developer experience: Do developers have experience with an existing platform, or do they need to learn a new platform? What is the learning curve for a new platform like? SAP Commerce Cloud needs Java/Spring background (and maybe Angular for their latest frontend technology).
Community / Support: Is there a community where you can ask questions in case you have a problem? Are there documentation / blogs available?
Future of technology: Is the platform continuously improving or "future-proof", or is it content with staying with old technology? For example, SAP Commerce Cloud's frontend is moving towards Angular, instead of its own technology.
etc
#geffchang already share some information in his response. I want to add my personnel parameters:
Business processes: Every company has own business processing for preparing products, photos, campaigns, prices, page designs. Some solution has work flow and roles for these changes. If your company small and few people manage it, these work flow steps get extra workload. On the other hand some companies need to approve every changes.
Search engine capabilities: Some products use special search engines such as Solr, Elastic Search, etc. These solutions can manipulate search result, built in synonym and search with root of word support.
Other e-commerce related tasks: Some product has solution for other e-commerce related background tasks. Such as taken product picture, marketing emails/sms, mobile app, wharehouse/stock management, payment integration, cargo integration.
Sector/company related functions: Some solutions has extra functionalities which are not needed for all companies. Such as multi brand capabilities, auto publish new pages/campaigns, ticketing system, region/country/segment based prices, products and pages, business reports (stock, sales, etc.).
At the end, you need to list client needed functionalities and short term future plans then find best fitting e-commerce software for them.

I'm working with my brother on a website idea we have, and we'd like to use a tool to plan sprints and assign estimates to individual tickets.
Atlassian's JIRA+Greenhopper looks fantastic but costs $20/month and at this stage we're just validating our idea and would rather not spend money on a tool if we can avoid it.
Are there any free alternatives to these tools?
Taiga is 100% free and has all the features that comes with something like JIRA.
http://taiga.io/
It even has a burn-down chart! So that's a win!
Here's a site with a nice overview of what Taiga integrates with and real developer opinions on the tool.
http://stackshare.io/taiga
Trello is a good tool for creating task boards and tracking work for small teams.
https://trello.com/
I get this question a lot as a Scrum Trainer.
I strongly recommend Index Cards and a Physical Scrum Board. While it won't calculate time addition for you, that task is trivial and the 'information at a glance' that a Scrum Board offers is hugely beneficial.
If you absolutely HAVE to have an electronic board, try Visual Studio Online (TFS in the cloud) which, at present, is free for up to 5 users.
Another option (We use Jira) would be YouTRACK. http://www.jetbrains.com/youtrack/buy/
It is free for up to 10 users and seems to offer pretty much the same functionality.
DISCLAIMER: I have never used YouTRACK on any level. IntelliJ is a great product though.
For Agile project management, I have used extensive Thoughtworks - Mingle
It's free for 5 users.
Another good alternative could be agilefant. Agilefant offers a free and open source product that can be downloaded and deployed into your own private cloud.
If you are looking open source project management, which you can host on your own, the following list could be useful:
ProjectLibre is a java based ms-project rich client alternative
LibrePlan is a rich client and based on these videos it seems like ms-project and includes hours spend by user on task, collaboration was not visible in the videos
OpenProject is a web based software with features such as issues, time lines (gantt chart), calendars, meeting notes and more
Redmine is a web based software using the Ruby on Rails framework that includes issues, work log, a wiki and a gantt chart and more.
You can also check TargetProcess (http://www.targetprocess.com/pricing/) it's free for 5 users
i use it for three months and it's very good
I used Trello (http://trello.com) and Mingle (http://getmingle.io) on two different projects. Trello is great for tracking tasks and collaborating for small team. My trello project team had 3 members, we were distributed. We also use Google drives to track unstructured information. My mingle project team have more than 10 people, and used it for years. Team love using it for standup on big touch TV and different roles (BA/QA/PM) like it because you have have your own workspace track different tasks and sometime build their own report).
IceScrum.
It's open source and you can run on your own server.
The best open source project planning in my opinion!
https://www.teamwork.com/pricing
"If you don't pay after the 30 day free trial you can still use Teamwork Projects free forever"
"We also have a Free Forever Plan with 2 projects and 100mb space"

I am using Redmine and as a free software it is more than good.
But I'm facing some problems now and I'm looking for some system to replace Redmine.
Main disadvantages from my point of view are:
hard installation - My version is 1.3.1 (installation process was pain in the #$$), now when I want to upgrade to 2.. I can see in the site that this will be pain too
not so stable - (using stand-alone nginx server) there are some problems like sometimes cannot upload files until restart passenger, stopped working two times (passenger process missing for some reason) etc
my last attempt to set-up a plugin was unsuccessful
I'm not Ruby developer and it's hard to maintain the Redmine - I'm pretty not sure what are the security issues, how to use Redmine with already installed SSL on one of the domains (port 80) etc
So I'm looking for a new system (preferred /but not mandatory/ option to be NOT SaaS) with these features:
Required:
Project management
Bug Tracking
Possibility to generate Invoices (as a plugin is cool too)
User friendly interface
Good to have:
openID login
not necessarily free (but for a reasonable price)
if it's not SaaS - to be PHP based, not Ruby, Python, Java etc
I have some experience with Assembla, Pivotal, Yodiz and Mantis.
Yodiz interface is too complex and not clean for me.
Mantis is like from the past (looks like the first tracker ever)
Pivotal is not so bad, but I think is best for issues tracking only (not project management, invoices etc)
Assembla.. very little experience, only for SVN
I know there are lots of discussions, the problem is that many people liked Redmine for some reasons that are totally opposite of my opinion.
I'm spending some time last 2 days to review most popular trackers, but with no success so far.
I'll try "Trac" now, but will be glad if someone share it's experience with this popular Trac problem - multiple projects. :)
Thanks!
I would suggest to take a look at assembla. It is not for SVN only - you can use git / svn / mercurial tools or even add external github tool.
Project management for assembla recently got much better (with implementation of Planner and Cardwall) and new improvements are planned.
If you track your hours in commit messages or web interface, it is very easy to export the working hours (to generate an invoice)
After some research I found needed software.
FengOffice seems to fit my requirements very well.
community version (free)
self hosted (2 minutes installation)
written on PHP
very good UI - I like the way it's organized, AJAX UI is very good implemented in this case
cool features
.. etc
I don't have more detailed impressions, but it looks really promising.
The current Trac version (1.0) does not natively provide multi-project support, although there is some discussion about that topic in the Trac wiki. But since Trac 0.12 there is a plugin SimpleMultiProjectPlugin that extends Trac with the feature 'multiple projects in one installed Trac instance'.
A good description of what that Trac plugin SimpleMultiProjectPlugin exactly provides can be read here or on the plugin wiki page (see link above).

I was asked to manage and develop a project. The client does not really care if I hire people who would do it or I do it myself. Thus, I've decided to be more manager than developer.
Are there any (free / low cost) web projects that could help me to communicate with each "sub-developer" outta there on Internet?
What I expect is to have similar project as basecamp, however sub-developers wouldn't know about each other because I would be communicator between them. It's possible that basecamp includes this kind of service, but I am not going to pay to every possible similar service to know this.
If you have some real-life experience with this kind of problem I'm about to encounter, please, write it here.
Thank you
As many open source projects found, trac is a good fit - lightweight project management with integrated subversion interface:
Trac is an enhanced wiki and issue tracking system for software development projects. Trac uses a minimalistic approach to web-based software project management. Our mission is to help developers write great software while staying out of the way. Trac should impose as little as possible on a team's established development process and policies.
It provides an interface to Subversion, an integrated Wiki and convenient reporting facilities.
Trac allows wiki markup in issue descriptions and commit messages, creating links and seamless references between bugs, tasks, changesets, files and wiki pages. A timeline shows all current and past project events in order, making the acquisition of an overview of the project and tracking progress very easy. The roadmap shows the road ahead, listing the upcoming milestones.
Both trac and subversion can be used from anywhere on the Web, using one of the free or low cost providers (for some references, see TracUsers).
I'd set up sharepoint if i were you. It's perfect for handling projects and talking to members. Also set up a couple of mailing-lists where you all can easily communicate.
Good Luck
I would suggest looking at Assembla, it has issue tracking, version control and Trac support all in it - and it's free.
It is possible that you can do this with the free version of AceProject.
There are quite a lot of software available to manage projects easily, here I'd suggest you to check out ProofHub - https://www.proofhub.com (heads up - I work there). It allows you to capture both the full picture and a detailed snapshot of your plans and progress. The Gantt charts and task management feature provide clear picture for you to understand what is being worked on and what needs to be done. You can track task dependencies on your Gantt chart to see the progress of your projects. Here's how it looks:

I've recently begun evaluating a few project management projects for the company I work for. It's the classic case - growing company looking for the right solution (meaning, free or really cheap). It's a combination shop - Windows, Macs, and Linux on the desktop. The tech savviness, of course, ranges from newbie to unix guru.
I have yet to find anything really close to a total solution. I don't expect to find one, but I am looking for suggestions/guidance/any sort of feedback based on people's experience.
What I'm looking for:
web based
methodology independent (not looking for an agile solution, etc.)
free or really cheap
document management
timelines and milestones
task tracking and assigning
reporting
source control
development wiki
I've looked at Trac, Projectivity, Basecamp, JIRA, RT, XPlanner, and SharedPlan. I've stayed away from Bugzilla due to previous unhappy experiences with it. None of these things really does everything - some are extendable, but I'd check here before going down that path.
Thanks,
Read through Edward Tufte's long-running Ask E.T. topic Project Management Graphics (or Gantt Charts). There is no consensus answer, but a lot of things have been evaluated.

Trac - integration of tickets / wiki / commit-comments is great.
Caveat: installation can be PITA...
Check out Jira Studio. All of Atlassian's apps, hosted for you.
http://www.jira.com/
You get wiki/tracker/svn browser and more.
Have a look at Redmine, it's a Rails app. Haven't used it yet myself, but thinking about moving to it from activecollab. This applications seems to be evolved quite fast last year.
My experience of Jira (with Confluence for the wiki) has been rather good, although it is quite pricey the support people were very responsive and helpful. The place where I used that had svn for version control, and the two played together OK. On the other hand I found Xplanner to be a very odd app - really inflexible if you don't want to be doing XP, and surprisingly documentation-centric for an XP shop.
If you don't mind doing a bit of configuration yourself and have a windows server somewhere in your shop then you could set up your very own customized project management system in SharePoint.
* web based
* methodology independent
* free or really cheap
* document management
* timelines and milestones
* task tracking and assigning
* reporting
* source control
* development wiki
The source control system is not a part of SharePoint so it is really a question whether that requirement is paramount or not. But besides that you will have all of the above for free if you install WSS (comes free with a 2003/2008 server)
There is even a book from O'Reilly about how to set up a PMIS in SharePoint
One solution for the more visual of us would be to use Drupal 6x. with the Project and Subversion (now Version Control) modules. I prefer Joomla with ProjectFork, but until its modded with a repo browser, this will have to do.
Hope this helps.
http://drupal.org/project/project
I looked hard at Alfresco and Joomla.
None met my needs because I wanted the ultimate in simplicity. But, you seem to prefer having the kitchen sink included (while keeping it easy to use, I guess), so either one of these might be right for you.
Currently, I'm throwing together my own using Django, keeping only the project-deadline, forum and file-versioning concepts.
