Few days ago I had a installation problem package revoIPC 1.0-3 and doSMP 1.0.1. When I was compiled revoIPC 1.0-3, compilator returned this error:
g++ -I/usr/local/lib64/R/include -I/usr/local/include -I . -fpic
-g -O2 -c interface.cc -o interface.o

ERROR: compilation failed for package ‘revoIPC’
Rich Calaway from revolutionanalytics.com helped me quickly and sent solution. The patch with fix this problem is a:
„… go to src/boost/interprocess/detail/iterators.hpp and comment out lines 341-353″
Thanks for this advice we can compile revoIPC 1.0-3 and use it in with doSMP 1.0.1. Just one thinks, if we use doSMP 1.0.1 in new revoIPC 1.0-4 and we try execute this program:
rmSessions(all.names = TRUE)
w <- startWorkers(2)
registerDoSMP(w)
foreach(i=1:3) %dopar% sqrt(i)
R return this error:
> foreach(i=1:3) %dopar% sqrt(i) *** caught segfault ***
address 0x7fd0e562f58c, cause ‘memory not mapped’ Traceback:
1: .Call(„returnResult”, q, t$task, serialize(res, NULL))
2: ipcTaskReturnResult(taskq, taskchunk, resultchunk)
3: doSMP:::workerLoop(qname, rank, verbose, out)
aborting …
Rich Calaway helped me fixed this problem to. I don’t check it but if someone want to use revoIPC 1.0-4 must:
„… remove the PKG_CPPFLAGS=-DNDEBUG line from Makevars.in in the src directory.”
Good luck.

For few mounth I created a data mining review – „Data mining review and use’s classification, methods and techniques”. This article can finds in Studia i Materiały Informatyki Stosowanej (SIMIS, http://www.simis.ukw.edu.pl/) if he will favourably reviews. Below I represended abstract of this paper:
The large quantity of the data and information accumulated into actual information systems and their successive extension extorted the development of new processes, techniques and methods to their storing, processing and analysing. Currently the achievement from the statistical analyses and artificial intelligence area are use to the analysis process of the large data sets. These fields make up the core of data exploration – data mining. Currently the data mining aspires to independent scientific method which one uses to solving problems from range of information analysis comes from the data bases menagments systems. In this article was described review and use’s classification, methods and techniques which they are using in the process of the data exploration. In this article also was described actual development direction and described elements which require this young applied discipline of the science.

I finished implementation a questionnaire for fire service on the previous day. This questionnaire was implemented for quantitative/qualitative research. The destination of this research is a creation a hybrid decision support system for Polish fire service. It’s a complicate problem which require many of different researches. This research integrate solution from logistic, transport, game theory, artificial intelligence, linguistics, retrieval of text information like a text mining and especially text reprezentation and his processing. All project was described by process of design for trustworthy software (DFTS). The results of investigations will be published after the completion questionnaire by respondenst.
Questionnaire was implemented using web technologies like a JAVA+JSF+Hibernate+MySQL.

First step in investigations is a create of hypothesis. Hypothesis is a question or assumption of results. In next step is created a proof which negated or confirmed hypothesis. After that is received a thesis. Thesis plus proof equal theorem.
In this post was described a simple model of theorem which have a multi conclusions. In next part for another day I will try explain this conclusions.

This day I spend on writing some part of article about what’s konowladge mean. I defined a formal model of knowladge and I hope that I could public this material in SGSP jurnal for a few mounth. When this aricle will be publish I will wirte about it in this blog.

In this time, weekend day I spent for a modeling a new approach to building decission support system for fire service. I hope that in next few day I finis this question and somevher I can public this material. Actualy I done work and go away, It’s time to begin a Saturday hot nite.
