As my question was remained unanswered in Rapidminer forum via this address :
my original question
I would like to propose it here again, please inform me if by any chance you know the answer.
I have noticed no matter what type of extensions we use for getting export (i.e. .pdf, .ps .jpg , etc), the export engine do like a screenshot of the current view instead of the whole output space, this has caused lots of issues for me exporting gigantic decision trees of my research.
Please someone advise me on this issue.
Best,
Amir
Use the log operator at the end of your process and configure it by the information you need. The log operator will save all results in a text file. Based on this file you can generate all your graphs at any time using rapidminer or gnuplot...
I find this way the best to save your time and memory space and also very easy to share in my opinion.

We have a need for "Blending of hits from different sources", as per your documentation it is recommended to write a custom-searcher in JAVA. Is there a demo of this written somewhere on Github ? I wouldn't even know where to start :( I understand I can create search "chains" , preferably Asynchronous, and then blend results in JAVA before returning them...but then how would I handle paginations, limits...etc ? This all seems very complicated, for someone who doesn't even know JAVA that much. So, I am hoping someone has already written a demo for this ? Please ? Anyone ?
Thank you so much
EDIT to make my quesion clearer:
We are writing a search engine that fetches data from various websites. Some websites have 10mil indexable items, other websites only 100,000. When we present the results to end user, we want to include results from all our sources ( when match applies ). Let's say 10 results from each of the websites we crawl, so that they all get equal amount of attention on page. If we don't do custom blending, what happens is that the largest website with most items wins all our traffic.
I understand that we can send 10 separate queries to VESPA, and blend the results in our front end, but that seems very inefficient. Thus, the quesion of "Custome Searcher". Thank you so much !
That documentation covers some very advanced use cases which you do not have. Are your sources different Vespa schemas or content clusters? If so Vespa will by default blend the hits returned from each according to their relevance scores so there's nothing you need to do.
The two other most common use-cases are:
Some (or all) the data sources are external, so you need to write a Searcher component to fetch the external data and turn it into a Result.
You want the data to be blended in some custom way (rather than by relevance score). If so you need to exclude the default blending Searcher (com.yahoo.prelude.searcher.BlendingSearcher) and write your own.
If you provide some more information about your use cases I can give you some code examples.
EDIT: Use grouping to solve the need explained under "EDIT" in the question:
Create a "siteid" field when feeding (e.g in document processing).
Use the grouping expression all(group(siteid) each(max(10) output(summary())))
See http://docs.vespa.ai/documentation/grouping.html
I have the following question:
The calendar text file and binary file should have a name that with a fixed part and a variable part. Use the time function (in time.h) or some other automatic mechanism to make sure that, when you write the files back out after updating the calendar, you do not overwrite the files you read in but you write a new version of the file that is clearly more recent.
Knowing that I have a program that manages a calendar.
Is it possible to to create a file with a fixed part and a variable part using the time.hlibrary ?
Thank you in advance!
Your question is vague, so the answer could only be similar.
From your specification, I guess you need a filename, f.e. "calendar-YYYYMMDDhhmmss.bin" and "calendar-YYYYMMDDhhmmss.txt"
When you "man time.h", you can see, that the time-"library" provides all these data. At the bottom of the man-page you see some related functions like "time()" and "strftime()", which help you to get a timestamp and to format a time to your needs.
If you "http://www.whathaveyoutried.com" and are stuck again, please update your question, and we will help you further.
EDITH (to the comment):
That depends on whether you should have a lot of files with each containing one "calendar" and the most recent dateded file is the actual calendar and the olde ones are backups; or you have one calendar-file with a new section for each "calendar", then you have to define (for yourself) how to organise these actual and historical sections.
as a matter of fact i would prefere the first solution, so each time you update your calendar, you call "fopen(path_filename_timestamp_txt, "w");". In the second case you would call "fopen(path_filename_txt, "a");" and "fwrite(timestamp);" your section-header;
Please show us, what you have done so far! (as short as possible, according to http://sscce.org/)
The current XML Helper in CakePHP doesn't give you the ability to specify if you want the whitespace to be significant or non-significant. Normally it wouldn't matter, but I'm working with a strict API that requires certain values to have no excess characters surrounding the value (no \n's or \t's). I'd like to modify the Cake source to support this ability, and if anyone has done this before and has any tips or advise on how to start, I'd appreciate it. Actually I believe the most helpful thing would be if someone has a flowchart of how Cake comes together (ie: starts in index.php and flows through router.php or what-not). I'd like to get a better understanding of how Cake is constructed (even from a high level).
Thanks!
If you want to change one of the built-in helpers, just copy it into your /app/views/helpers/ directory and edit it from there. The version in your app will be used instead of the original.
I wonder if it is possible to embed dynamic text into Keynote'09? I want to create a new presentation and run this presentation with different text messages (depending on the time of the day and day of the month).
You can insert formulas in tables. I don't have the english version of keynote open, so I can't tell you the exact names of the functions (guessing). You can do something like
=IF(MINUTE(NOW()) > 30; "> 30" ; "<= 30")
See the formula help. If you tell me what you want to achieve, I can give you further details.
I'm not aware of any direct or easy method to achieve what you are asking for.
However, with AppleScript you can access and change at least the title and the body boxes of the slides. This should be done prior to the presentation.
If the 'dynamic' text is to appear in a text box, you could use some scripting to modify the presentation's XML directly. An older Keynote's XML schema should be reasonably well (but not wholly) documented in the iWork Programming Guide, but as the '09 file format is not backwards compatible I don't know how much that would help.
You could try using an encapsulated post script image file. Postscript is a real programming language. I don't know if Keynote will accept it (or if it will cache a bitmap), but Cocoa loads EPS, and Keynote is cocoa.
On Mac OS X, an EPS file gets evaluated when it is opened and converted to a PDF in memory. This process can take a really long time, like 30 seconds, if this is the first time you've tried to open an EPS file since logging in.
Ah! Someone pointed out to me that you can embed Quartz Composer compositions into keynote. This is a good way to do it.
When you take your first look at an Oracle database, one of the first questions is often "where's the alert log?". Grid Control can tell you, but its often not available in the environment.
I posted some bash and Perl scripts to find and tail the alert log on my blog some time back, and I'm surprised to see that post still getting lots of hits.
The technique used is to lookup background_dump_dest from v$parameter. But I only tested this on Oracle Database 10g.
Is there a better approach than this? And does anyone know if this still works in 11g?
Am sure it will work in 11g, that parameter has been around for a long time.
Seems like the correct way to find it to me.
If the background_dump_dest parameter isn't set, the alert.log will be put in $ORACLE_HOME/RDBMS/trace
Once you've got the log open, I would consider using File::Tail or File::Tail::App to display it as it's being written, rather than sleeping and reading. File::Tail::App is particularly clever, because it will detect the file being rotated and switch, and will remember where you were up to between invocations of your program.
I'd also consider locking your cache file before using it. The race condition may not bother you, but having multiple people try to start your program at once could result in nasty fights over who gets to write to the cache file.
However both of these are nit-picks. My brief glance over your code doesn't reveal any glaring mistakes.
