I have rapidminer studio 7.1, and I want to try sentiment analysis on twitter, but operator search twiiter cannot used. There is error "Operator is not supported by your current product edition". Anyone can help me?? please..
there is the screenshot : http://prnt.sc/b4z3k0
the access to Twitter is a feature of the Professional RapidMiner version, that is not available in the Basic or Community versions. So you might consider upgrading your license or (if feasible) apply to the academia program for students and academic researchers.
Otherwise the operator works fine in RapidMiner.

I am trying to help a niece to make a thesis on programming a software that will be able to store and retrieve scanned pictures using a GUI where we can input some parameters like name, unique id number, address and the like. Also, it should enable us to fill in some forms and then later on, we can print it. I have a little background in programming as I have tried VB6 a decade ago and never again ever since. I know that all these are possible with VB6 but it is obsolete now and I know that there are a lot of programming softwares out there that are more powerful and up to date. Can someone give me an advice on where to start and what programming language I can use now?
Since you are familiar with the VB6 syntax, I would think VB.NET would be a good choice for you. As a .NET language, it is fully featured and powerful. You can get Visual Studio Express Edition, or now Visual Studio Community Edition, for free. Check them out at https://www.visualstudio.com/vs/visual-studio-express/ and https://www.visualstudio.com/vs/community/
What has been the experience of folks who have already been using OpenDJ and OpenAM? Older versions seem free to use but the new releases don't seem to be free for use. How do they compare to the existing commercial offerings? They look like a better option than using OpenLDAP with CAS but don't look free.
Below you can find answers depending on when this question was asked just for the sake of history.
ANSWER AFTER April 3rd, 2017
With the recent changes made to the business model here you can find the key details you will need to know:
The latest versions of the main products have been firstly renamed, but secondly has been re-versioned to match ForgeRock's Identity Platform views:
OpenAM 14.0.0 -> Access Manager 5.0.0
OpenDJ 4.0.0 -> Directory Services 5.0.0
OpenIDM 5.0.0 -> Identity Management 5.0.0
OpenIG 5.0.0 -> Identity Gateway 5.0.0
The products listed above were all released under a commercial licence, meaning:
The ForgeRock contributed source code (i.e. ForgeRock's intellectual property) is not licensed under an open source licence.
All source code that does not solely belong to ForgeRock (e.g. original source code that belonged to Sun, or source that had open source contributor's work associated with them) will be still available under the CDDL licence and can be obtained as detailed under forgerock.org.
All ForgeRock IP is licensed under a non open source licence.
The products released under the commercial licence can be evaluated for 60 days only.
At the same time of the official release of the new products, community editions have been released for the Open* products:
The community editions are essentially the latest maintenance releases of the last EOL'd versions of the products.
Since these are maintenance releases, they are meant to be firstly more stable, but secondly slightly more secure (only slightly since these versions have not been updated to include the security fixes that have been issued since these versions' original release date).
The community editions can be found under forgerock.github.io
With these new releases every community member will have to make a decision themselves: do they want to go for the latest, but EOL'd stable version of the product, or do they want to try their luck with the latest public, but likely to be less mature software versions (like OpenAM 13.0.0 that was released before the business model change).
Whether community versions will be released/updated by ForgeRock in the upcoming years is currently unknown, no such information has been publicly provided.
Short of an official announcement from ForgeRock, please have a look at this topic in the ForgeRock forum for more details.
To summarize:
The Open* products are still open source and freely available, however they are no longer being publicly developed by ForgeRock. Whether new community versions will be made available is yet unknown, but given the current example, each year the community would get access to an EOL'd version of the product..
ANSWER BEFORE April 3rd, 2017
Here are some facts about the projects and the licensing in general:
Only major releases are made publicly available, which means the source code is available in the format of an SVN tag, whilst the binary that can be downloaded from BackStage will have the binary license on it.
The binary license allows people to test out the product, but it prevents them from using those binaries in production environments without support subscription.
Maintenance versions are not available publicly neither in source nor in binary format.
Each project's trunk (or master) is publicly available, which means that in one shape or form every single bugfix is available, so with some luck it should be possible to cherry-pick important fixes from trunk onto your own special maintenance version.
Each product is relatively simple to build (except maybe the web agents), and as such it shouldn't pose much of a risk to your deployment (ForgeRock does have customers who are building their own artifacts for their deployments, so it is really not a rocket science).
Downloading the artifacts from BackStage only requires some skills on working with agent protected applications, here is an example curl command:
$ curl -O -H "Cookie: fr_sso_sess_prod=AQIC5w..." https://backstage.forgerock.com/downloads/enterprise/openam/openam12/12.0.0/OpenAM-12.0.0.war
Unfortunately it is common that the major releases have some annoying bugs, for those, backporting is relatively simple, since the difference between trunk and the latest major release shouldn't be too big, so you should be able to handle those by manually backporting the fixes. Since major releases happen every ~year or so, you don't have to live with these local changes for too long fortunately.
The projects have active community, and getting help with any kind of issues shouldn't be too difficult (let it be a deployment issue or how to build the projects locally)
Probably I should mention that I'm a ForgeRock employee, so take my comments as you please.
Just to clarify: when you build trunk on your own, you do not have to buy subscription. Only ForgeRock enterprise builds should include the binary license. When building your own stuff, it is you who creates the binaries, hence you can simply decide to leave the binary license out of it.
I'll answer your question in two parts:
First as it compares to existing commercial it's actually a very good solution, as it scales, and it's very feature rich. You can go to the site and read all about the features.
The second part of newer version requiring subscription is somewhat wrong. Mainly because there are subscription downloads from forgerock.com. I assume this are for support service contract reasons that one must purchace. If you want to run the latest version just download the nightly builds forgerock.org, and you will be running the latest version. Lastly I will echo Ludovic's comments about the confusion of free.
[Community] - https://forgerock.org/
[Commercial Support] - https://forgerock.com/
PS. I'm in no way associated with forgerock.
I think you are confusing free as in Free beer and the freedom of open source.
This said OpenAM and OpenDJ are enterprise ready products, mature and used in a large number of mission critical environments including governments, telecom operators, financial institutions, insurances...
SQLite is available for WinRT. Is it possible to use SQLCipher with SQLite in WinRT applications? If not is there any other way to encrypt data in SQLite database?
It was released on windows phone 8 and windows RT platforms recently (though only like Commercial Edition, link below).
sqlcipher-for-windows-phone-8-and-windows-runtim
In general our goal is to have SQLCipher work on the widest possible range of platforms, so we are definitely interested in supporting it. However, SQLite only recently added upstream support for WinRT in 3.7.13, and we haven't had sufficient time to investigate what is involved with getting SQLCipher working there yet.
Please keep an eye out for future updates, or if you or your company has a funded commercial requirement for this sooner, reach out to us at support#zetetic.net.
I am getting into ActionScript-ing and SQLLite development.
What are the essential development IDEs and utility tools I should get set up for a smooth development experience?
It would be great if you categorize - as free and paid-for-software.
I am accustomed with the Microsoft "free" experience in terms of - Visual Studio Express edition or SQL Server Express edition.
Are there similar counter parts for this platform?
FlashDevelop - Open source IDE for flash but no visual designer. As far as SQLLite you can actually create and manage the databases all with actionscript but if you want to edit/create them with an IDE there are several open/free solutions, from a quick google search we have:
//SQLLite DB manager/admin tool made in Adobe AIR
http://www.dehats.com/drupal/?q=node/58
//Same idea but open source made with QT so probably C/C++
http://sourceforge.net/projects/sqlitebrowser/
//FlashDevelop
http://www.flashdevelop.org/wikidocs/index.php?title=Main_Page
Flashdevelop is pretty much king when it comes to code hinting/completion, pretty much what you'd expect in features from microsoft VS IDEs. There is also a pretty good user base and thus many tutorials/documentation and project templates.
I too use the DB admin tool formerly from www.dehats.com, which has since been renamed Lita and put on GitHub . However, a significant drawback to Lita is its complete lack of runtime error reporting when executing SQL queries.
Mauricio Piacentini is an excellent programmer, but Flash developers should be aware that his
SQLite Database Browser does not support the non-standard features added to AIR's version of SQLite, such as additional column affinity types.
So, as a complement to Lita I've been using Paul Robertson's Run! app. It doesn't have as many features as Lita, but it supports AIR's version of SQLite and it does report errors in your SQL queries.
Like Ascension, I'm a fan of FlashDevelop.

There seems to be a lot of press regarding the announcement that Intellij is being made available for free as an open source tool. Yet from what I read of the licenses, that's only true if the end product is open source and free. If you plan on selling your end product, you can't use the free community version.
Have I misread something?
Only a subset of IntelliJ, the IntelliJ community edition has been released as open source software. The page that you linked to describes a special license of the "Ultimate" edition (which is not open source), that they are specifically giving for free to people who promise that they will only use it for writing open source software for non-commercial purposes.
According to the FAQ, the new open source version of IntelliJ is available under an Apache license.
To clarify:
The community edition of IntelliJ is available under the Apache license, which means you can use it for whatever purposes you want, including writing proprietary, commercial software. It also mean you can modify the code of IntelliJ yourself, sell modified versions of it, anything like that, as long as you abide by the Apache license.
The community edition does not have all of the functionality of the ultimate edition. It only has some of the functionality; for instance, it has support for Java and Groovy, but not Python or Scala. But the community edition can be used for any purposes you want, as long as you follow the terms of the Apache license.
The ultimate edition (which includes extra functionality as listed in their comparison) normally costs money. However, they are also offering the ultimate edition for free to people who promise that they are using it for non-commercial purposes for an open source project (I have no idea how they would actually enforce this, but that's beside the point). I believe this is an offer that they've had since before they released IntelliJ community edition as open source software; as a way of helping out open source development, without giving away everything to everyone.
So, go ahead and download the community edition, and use it for anything you want, from developing free software to developing commercial software to modifying IntelliJ yourself and selling it.
IntelliJ has a licenses folder that you can check out; For instance mine is located under here JetBrains\IntelliJ IDEA 129.111\license
You can see that there is a file called IDEA_OpenSource_license.txt
GRANT OF LICENSE
Subject to the terms, conditions, and limitations set forth in this
Agreement, including any amendments thereto, Licensor hereby grants to

(a) Licensee may: (i) install the version of the Software that has
been specified in License Certificate on multiple Clients and
operating systems; (ii) use the Software by Authorized Users solely
for the purpose of development of non-commercial open source projects
that meet the Open Source Definition at

(b) Licensee may not: (i) sell, redistribute (except as set forth in

engineer, decompile, disassemble, modify, translate, make any attempt
to discover the source code of the Software, or create derivative
works from the Software, or (iii) use the Software for any commercial
purpose.
Which seems to completely go against what the Apache License allows you to do
I wonder if this is a relic of a previous License before it was open sourced?
Edit
Dmitry Jemerov has posted on the following on the Jetbrains blog [source]
IntelliJ IDEA Community Edition is completely free and open-source,
licensed under the Apache 2 license and can be used for any kind of
development. Android Studio has the same licensing terms.
You will find that the free version has most of the features of IntelliJ removed, so you can get experience with IntelliJ, but if you really want to do anything of complexity with it you will need to buy the full-featured version.
But, if you use the free version how can anyone tell which IDE you used to create the java source?
