I know the following may sound too basic but I thought the mailing list is for the benefit of all levels of people. I ran a simple if statement on two numeric vectors (news1o and s2o) which are of equal length. I have done an str on both of them for your kind perusal below. I am trying to compare the numbers in both and initiate a new vector s as 1 or 0 depending on if the elements in the arrays

We have 50 complex applications written in Microsoft Visual Basic 6.0 providing banking solutions. We are seriously thinking of porting our applications to Linux under WINE. Is it possible to do so? Nature of our VB applications: ------------------------------ 1. Extensively used all controls provided in VB 2. Total size of our applications is around 2 million lines 3. Applications are having

Dear all, Without a loop, I would like transform 3 numeric vectors empty of 0/1 of same length Vec1 : transform 1 to A and 0 to "" Vec2 : transform 1 to B and 0 to "" Vec3 : transform 1 to C and 0 to "" to obtain only 1 vector Vec who is the paste of the 3 vectors (Ex : ABC, BC, AC, AB,...) Any idea ? Thank you for your help -- Michel ARNAUD

Hi, I''m having a problem loading a sample data with simple rake command. rake db:fixtures:load When I run the above command,I get the following error $rake db:fixtures:load (in /home/raghu/www/photos) rake aborted! a YAML error occurred parsing /home/raghu/www/photos/test/fixtures/photos.yml.

I''m following along with the depot example in ''Agile Web Development'' and ran into a problem with Scaffold. I changed the MySQL table structure to add a few columns directly and also tried the migrate script to change the database after I got the initial scaffolding to work. However, I can''t seem to get the new columns to show up and am stumped as to how I can

Based on the feedback received, I did the following: a) moved my lib sub-directory from the existing installed R version to c:\myRLib b) installed the updated R version c) created .Renviron file in the home directory (C:\R-2.5.1) with the line R_LIBS=c:/myRLib d) used .libPaths() command to confirm that the new R installation was recognizing the myRLib sub-directory e) deleted my old R

Hi I have 2 data.frames each of the same number of rows (approximately 30000 or more entries). They also have the same number of columns, lets say 2. One column has the date, the other column has a double precision number. Let the column names be V1, V2. Now I want to calculate the correlation of the 2 sets of data, for the last 100 days for every day available in the data.frames. My code looks

Dear Folks, Is there a documented case of earliest use of rsync over internet? I presume rsync was used almost as soon as internet was invented as a file transfer and bandwidth efficient backup solution. If anyone has any information, please respond. -- Raghu Kulkarni

The topic of Ra and jit has come up on this list recently (see http://www.milbo.users.sonic.net/ra/index.html) so I thought people might be interested in this little demo. For it I used my machine, a 3-year old laptop with 2Gb memory running Windows XP, and the good old convolution example, the same one as used on the web page, (though the code on the web page has a slight glitch in it). This

Have you added the $LLVM_INSTALL_DIR/bin to your PATH environment variable? Regarding changing a particular backend, check the documentation in http://llvm.org/docs/WritingAnLLVMBackend.html http://llvm.org/docs/CodeGenerator.html A few LLVMdev meetings have good talks to give you a good enough idea. http://llvm.org/devmtg/ Cheers, Raghu. ----- Original Message ----- From: "Teklu

Hi I am new to llvm and Linux (I am using ubuntu 10) My aim is to add backend to llvm. I install llvm using $ sudo apt-get install llvm and I am able to understand what I read about Writing an LLVM Compiler Backend. I have seen the assembly codes of the targets on llvm using llc. What I need now is to change some of the TableGen files of one of the target like SparcInstrInfo.td.  So I

Hi all, I have started using LLVM recently, and I have a basic question. There are two different ways in which an executable can be generated from a .c file - by just using llvm-gcc, and using a combination of llvm-gcc (to emit bitcode .bc), llc (to emit assembly code), as (to assemble the code) and collect2 (linker). For example, consider compiling test.c : 1) llvm-gcc -O3 test.c -o

I use BDRb to process RSS feeds for users on my site (http://feedflix.com). I have a batch job that queries the DB for records that haven''t been updated in the last so many hours and kicks off a background job for each of them. If N records are returned by the DB, N background jobs gets queued and get done serially. As long as N is 255 or under, everything works like a charm.

Hello all, I am trying to modify the Sparc backend to do something for my team's project, to do the following. Whenever the backend encounters a call to one particular type of function names (functions like p0(), p1()..etc), I want the backend to generate a "sethi %g0, <number>", and NOT a "call p0, call p1..." instruction. However, the backend should work as usual

Hello all, I get this intermittent error saying OpenURI::HTTPError. At the bottom of the email is what is reported in my backgroundrb_server_<port>.log file. The process_netflix_reviews method is parsing (in the background) Netflix''s RSS feeds. This error also pretty much brings down the BDRb process and to recover, I am forced to do a ./script/backgroundrb stop

Hi Tim, Thanks for the patch. I had a few questions though - just to make sure that I get the problem correctly. Currently, here is your flow, as I understand it : x86 llvm-gcc binary llc -march=sparc gcc cross/sparc source ---------------------> .bc ------------------> .s -----------------> sparc executable. Is this correct? Or did you manage to build the

Hi I have a sorted array ( in ascending order) and I want to find the subscript of a number in the array which is the the next highest number to a given number. For example,if I have 67 as a given number and if I have a vector x=c(23,36,45,62,79,103,109), then how do I get the subscript 5 from x (to get 79 which is the next highest to 67) without using a for loop? Thx -- 'Raghu'

Hi I have say a large vector of 3500 digits. Initially the digits are 0s and 1s. I need to check for a rule to change some of the 0s to -1s in this vector. But once I change a 0 to -1 then I need to start applying the rule to change the next 0 only after I see the next 1 in the vector. Say for example x = (0,0,0,0,0,0,0,1,0,0,1,1,0,0,1,0,0,0,1) I need to traverse from the 9th element to the last
