Ning provides a structured content dump of Ning sites when requested. I was wondering whether a) the schema for this dump is publically specified and b) any open-source web applications can use such a dump to populate a community website.
FWIW, if dump format is not yet published, it certainly will be by the time when networks are asked to start paying, and there will be flow of requests. I don't know details of format, but I would expect it to be in JSON or possibly in XML (maybe both alternatives are given).
Given that there may be a few networks who want to do, I would bet on tools being built by some network creators. Activity on creator network is quite high, and people seem helpful, so you could try asking this question there (if you haven't already).

I have a few questions:
It is possible to implement a "private messages" within GetStream?
Or, for example, can I combine Getstream API with http://social-stream.dit.upm.es/ ? (this system written on ROR).
It is possible to control and change algorithm, how Machine learning works in getstream.io ?
I mean, I found not much information about Machine learning in documentation and getstream account. Maybe I can read about it somewhere in more detail?
Machine learning works only on paid plans or in free plan also?
getstream.io have specific API for Machine learning purpose?
For example, if we write some additional features, like "private messages" on our side, which GetStream don't have in API, how we can apply Machine learning on this new features?
You may ask, "why you need a Machine learning for PM"?
Not only PM. Here a few examples:
a) If user have some keyword in PM - we can determine what the topic is interesting to the user.
b) In another scenario - we can analyze images (we use our engine for that purpose) in posts and if some image contain correlation between keywords and specific topic and if we look at who like/vote this image - we can show him more relative content.
c) There is dozens another examples, which we need to control Machine learning process.
Even if we implement Machine learning on our side (from zero, just "for private messages" and other related stuff), how we can connect our results in machine learning with results in GetStream? If we will use it separately, it can be inefficient and bring unpredictable results (even negative).
I want to clarify, I am not a developer. I am owner, but understand very well the project management and the entire development process.
My question is a lack of understanding of how the API works.
Thanks in advance!
Stream helps you build activity streams and newsfeeds. A central aspect of that is the follow relationship. The same building blocks also make it easy to build notification feeds and private messages. Stream isn't build for private messages, but we have dozens of apps using us for that purpose. It works for many apps, but depending on your feature set your milage may vary.
As for your second question. Stream provides scalable newsfeeds, analytics and personalization (machine learning). For larger customers we extensively customize the machine learning component. There are similarities between apps, but it's definitely something which needs to be tailor made. At the moment analytics and personalization are only available to our largest customers. More information can be found here: http://getstream.io/personalization/
Using your own machine learning and Stream's at the same time is pretty easy. You simply track engagement events both in Stream and in your own system. That will allow you to run your own analysis.
Is there a way to monitor statistics on usage of documents within a database?
I have a lotus notes database hosted on a local server. I know I can get some info from 'User Detail...' in Info tab of Database property (right click on the database from domino designer), which basically shows me which user accessed database and which CRUD action was performed, but I was looking for something more in depth i.e. which document in particular is read the most and by who.
Since this is StackOverflow, not SuperUser or ServerFault, I'm going to treat this as a programming question. (On those other sites, they would tell you that tracking actions at the document level is not built into Notes and Domino's functionality, but there are some 3rd party add-on products that can do it for you.)
You can implement tracking features down to the document level in Notes and Domino using the Extension Manager API portion of the Notes C API. There is also a free package on the OpenNTF.org web site, called TriggerHappy, which provides a framework for using the Extension Manager features to call Java agents when events that you want to track occur. This can make it significantly easier to accomplish what you want, but it will not scale as well for large user bases.
You should also bear in mind that since Notes and Domino are designed for use in a distributed environment in which users can do their work in local replica databases, a tracking mechanism that is based on an Extension Manager plugin running on the server may not see changes at the moment that users make them. Instead, it might see them when those changes replicate from the user's computer to the server -- and replication does not guarantee that order is preserved, so the server might see some things happen in a different order than what the user actually did.
Have a look at the activity trends, see notes help.
If you need more details, you have to implement it by yourself.
I am looking to create a simple mobile agent system which will deal with 4 tasks, i.e 4 different mobile agents jobs: Database update, meeting scheduling, network services discovery and kernel update.
I have done my research and have seen different frameworks such as Aglet, Jade, agent builder etc. My question is which one should i use? Also i need to setup the base code for it to work, can someone point me to a site or help me to setup the basic functions of the mobile agent?
I've read about tahiti server for the Aglet model. I'm quite confused about how to set up the mobile agent system. Any help would be much appreciated.
I have also tried to it using RMI. I had created a method of type agent, but i couldn't pass it through remote method implementation. I was reading about tcp and udp socket programming. I was thinking may be it would be more fair to do it using socket programming. In this case, would this be called an agent? I was thinking about the server sending datagram packets to multiple clients.
You need to ask yourself why you want to use mobile agents at all. The notion of a mobile agent was popular in the agent research community in the early 90's, but fell out of favour because (i) it wasn't clear what problem it was solving, (ii) the capability to allow arbitrary code to migrate to a particular computer and execute with enough privileges to access local data and services is very open to abuse, and (iii) all of the claimed benefits of mobile agents can actually be achieved though web services (REST or otherwise) and open data formats such as RDF. Consequently, few, if any, mobile agent platforms have been properly maintained since the early experiments.
It also sounds as though you need to be clear which end-user problem you want to solve. Scheduling a meeting and updating my kernel are very different tasks - I'd be very uncomfortable with a program that claims do both. If your interest is in the automation of system maintenance tasks, such as DB tuning and kernel patching, on large networks you might want to look at the SmartFrog project, or read up on autonomic computing.
I use JADE and I agree with the first guy, agent systems usually take alot of overhead to going so if you can avoid it, please do. If however you choose to proceed choose a platform with alot of support and a big user group.
Jade has some neat features like a directory facilitator DF, which works like a yellow pages so other agents don't have to know what agents are running and what services are supplied they can simply inquire by the DF.
Also JADE ContractNetBehaviours help simplify communication.
I'm sure many of you are familiar with the IBM i5 series emulator (looks like this poop)
My company uses this religiously and there is no Biz logic in it so anytime somone in our finance dpt makes a human error it accepts it and adds it to the database. Not to mention its ugly, hard to use, not intuitive, etc....
I would like to create a frontend for this interface so that we can control the logic before its submitted to the system (we dont control the system itself) so in effect I need to make my own emulator app.
However I cant seem to find any information on how to interface with the i series, namely login, send commands, and view or gather data from the screens it would normally send back.
Any suggestions?
The problem is not the iSeries but the software package your company is running on it.
There ARE advantages to use green screens: it's fast and it's almost unbeatable at data entry, provided you get used to it.
But to answer your question, the iSeries is a J2EE enabled machine: a HTTP server comes installed and depending of the version of the iSeries, WebSphere might be already installed, or are entitled to install it. Then you can use JT400, which is the java toolkit for the os400 containing the jdbc drivers to connect the database and the necessary classes for calling programs.
If you prefer php, there is a flavor of the Zend framework made to work on the iSeries but I never tried it.
I'd recommend that you take a look at both the Attachmate Verastream Host Integrator (VHI) and IBM's Host Access Transformation Services (HATS) products. They effectively just screen scrape the green screen terminals to allow you to pull and push data and provide macro recording and editing tools to automate the process. App integration can be achieved via web services or html/jsp/servlet programming (plus .Net for VHI and EJB's for HATS). They do come with enterprise pricing however which may be an obstacle for some. They do have free trial offerings for evaluation purposes to help determine if they are an appropriate solution to your problem.
What software packages are they using? Most programs that I use in the 5250 emulator has some business logic that error checks the data before adding it to the database. Can you get us some more information so we can direct you in a better direction.
There are vendors that sell products that screen-scrape the 5250 data stream and produces a web front-end. Or you can write your own front-end in the language of your choice and just do SQL calls to the database.
THere's got to be some source code. Start by looking at the menu and menu option your users are accessing and figure that's running behind them.
Use command STRPDM to look for source code - look in different libraries (they are like folders)
You might have source code in a "member" called something like xxxMNUSRC xxxRPGSRC (rpg program source) or xxxCLSRC (cl programs), xxxDDSSRC (display/screen source, physical/logical file source)
Objects a "compiled" objects such as files (tables), screens, priter files (reports)
Stay away from Qxxx and #xxx libraries - those are system libraries.

I have been looking at the "_layouts/SpUsageSite.aspx" logs for my site, but they are giving erroneous results (eg 0 unique visitors when I know at least I have been on the site)
What is the best way to see these logs in a better way than the ootb functionality?
Did you enable the usage processing and the usage logging for the site in question?
You can enable them in you central admin under:
Operations -> Usage analysis processing
It may also be that the processing is limited to a speciffic timespan
I have come across a bug with the Usage analysis processing to do with UTC date conversion which resulted in the processed numbers being erroneous. This is apparently fixed in SP2, but we have not been able to implement this quite yet.
The alternative is a bit onerous as you need to copy the usage logs from each front end server to a location and configure the log parser to store the information in a data base.
Serge van den Oever steps through this quite well here.
I don't really recommend this as a regular process as it takes a lot of effort, but it does give you a huge amount of information for when you wish to take a detailed look at usage on a particular point of your SharePoint farm.
Ideally we would have a solution to parse the logs automagically using the log parser utility and provide that information in SSRS reports.
We patched to sp2 and it all started working again like magic.
