Dear all, I have been trying to speed up a process we have been done in ArcGIS. We have to read a single layer TIFF (monochrome image) in . For this, I have used the "rtiff" package. After reading the TIFF file, I compared the raw values for each pixel that I have in ArcGIS to the ones obtained in R. In ArcGIS I have discrete values in the range 0..255, while in R I have continuous

Full_Name: Julio Rojas Version: 2.2.1 OS: XP Pro Submission from: (NULL) (213.60.4.253) I was debugging a program with browser "()", made a couple of "plot"'s within the debugging console.

Dear @ll. I have to calculate numerical integrals for triangular and trapezoidal figures. I know you can calculate the exactly, but I want to do it this way to learn how to proceed with more complicated shapes. The code I'm using is the following: integrand<-function(x) { print(x) if(x<fx[1]) return(0) if(x>=fx[1] && x<fx[2]) return((x-fx[1])/(fx[2]-fx[1]))

hi, I'm trying to compile OpenSSH, latest version on my Linux box. I know that it requires openssl and I've installed the 0.9.5a and it's working just fine. Now when I'm trying to ./configure the openssh with the options ./configure --prefix=/usr/local/bin/openssh/ --without-pam --without-shadow --with-tcp-wrappers It's giving me checking for openssl directory... configure:

One of my accounts was having login failures when trying to send mail, but was able to check mail. I tried everything I could think of to see what the issue might be, but eventually went in and reset the password in the sql database (I knew the password, so I reset it to the same password). {SHA256-CRYPT}$5$VuS? {SHA256-CRYPT}$5$VI7? So the password was updated properly. Clients can still

I was just thinking last night, how about this: For each frame, detect edges and divide the frame into a bunch of non-overlapping polygons. Extract textures from the first frame, then save changes in polygon vertex coordinates only, unless the textures change too much in which case new textures (which could be wavelet compressed) would be stored. Also, if the movements of the vertices would

Hello All, I am hoping someone can help me. I am having a nightmare of a time trying to get rSpec to work. It was working at one time, but I tried installing Zentest to get autotest to work with rSpec and it''s been downhill ever since. Here are the gems I have installed in my rails app: ZenTest 3.6.1 if it matters (technically this is in my Ruby gems list and not in my vendor

I have written a bash script (see below) to generate bootable SD-USB images using syslinux as booter. The script works OK with versions 3.63 and 3.71, but I get a null pointer error executing /tmp/$SYSLINUX/linux/syslinux -sf -o 16384 SD.img in 3.72. If you execute $ sudo sh SDformat.sh sys then you can test the image easily with qemu $ qemu -hda SD.img ++++++ SDformat.sh

First of all congratulations on reaching alpha status. I was wondering if you people are implementing multiple layer support into the codec. I don't know if it should be in the container (ogg) or codec (theora) but perhaps the syncing requires at least support in the codec. For example a commercial: a cup of hot chocolate with steam escaping. Little action, low bandwidth. Then comes the

Hola, lo primero muchísimas gracias a todos por las respuestas que me habéis dado. Precisamente, lo que busco es una solución opensource para realizar informes con los resultados de R. Que permita cierta maquetación como LaTeX, y sobre todo una impresión correcta (que no corte las imágenes como ocurre con markdown/html). Y si dicha solución está orientada a servidor pues mucho mejor. Respecto a

Hi, I have an extension which has the follow me option activated. The followme option should go to a IVR if no answer... The problem that I have is that everything works when I'm calling it from my extension, but if I use any landline phone or a cell phone, I'm unable to enter any options. When I press one option, it seems I do nothing... Please, could you help me? Thanks, Anahi
