It's a pity I don't know how to re-create the issue. While there are 1-2 crashed clients in total 120 clients every day.

hi, I''ve got the following tables in mysql notation: CREATE TABLE `nodes` ( `id` int(11) NOT NULL auto_increment, `parent_id` int(11) default ''0'', `group_id` int(11) default ''0'', PRIMARY KEY (`id`), ); CREATE TABLE `groups` ( `parent_id` int(11) NOT NULL default ''0'', `id` int(11) NOT NULL auto_increment,

Hi, I would like to get started with RoR, since it seems to be a terriffic platform for Webdevelopment. However, I''m unsure what "level" you need to be on in terms of programming to get started? Best regards, Gustav -- Posted via http://www.ruby-forum.com/.

Hello, to implement some some kind of optimistic locking, I want to build a view, where an object is displayed together with a link containing the data of the displayed object. My first try looked something like <%= object.object_discription %> <%= link_to "action", :action => "take_action", :data => object %> this won''t work because object is of

I have a situation where I want to duplicate an ActiveRecord including duplication of has_many relationships. I''ve seen a few plugins but it seems unclear if they will work on Rails3. So I was wondering if anyone has a good suggestion for a plugin they are currently using to do this? Basically I''m doing this because I have an object that I want to allow my users to edit. I

Is putting a variable into a list a deep copy (and is tracemem the correct way to confirm)? warmstrong at krypton:~/dvl/R.packages$ R > x <- rnorm(1000) > tracemem(x) [1] "<0x3214c90>" > x.list <- list(x.in.list=x) tracemem[0x3214c90 -> 0x2af0a20]: > Is it possible to put a variable into a list without causing a deep copy (i.e. if you _really_ want the

Does LLVM offer any way of obtaining a deep copy of a CFG, that is all the basic blocks of a function and their instructions. I'm asking because I would like to implement continuations in my VM and I need to create a modified version of some functions. I thought a simple way of doing this would be to modify a copy of the code generated for the orignal function. This would be simpler than

I recently installed Samba 2.2.5 from the FreeBSD ports. It seems Samba works fine when browsing the Samba server from WinXP client, etc. I can copy files from the Samba server, and even create small files and copy small files TO the Samba server. The problem seems to be if I try to copy any file greater than 16Kbytes or so to the Samba server. When I do so, Windows XP complains with an error:

This is Red Hat Enterprise Linux 3.0 server.

It turned out that Samba can not handle the following situation: 2 network cards bonded together, and they are connected to different switches.

I''m seeing a "marshal data too short" error with an ActiveRecord store for my session data. Other posts say that this happens when the size of the session data exceeds the size of the "data" column in the sessions table. But my "data" column is a TEXT field so it seems unlikely that I could have blown it out. Has anyone else seen "marshal data too

I am handling spatial data of huge volumes, so sensitive to the silent duplication of data in script programs. In the following R program, exactly when is the vector data deeply copied? Thanks in advance. 1 v <- 1:10000 2 z <- f(v) --------- function f ---------- 3 f <- function(x) { 4 y = x 5 y[10] = 1 6 xf = date.frame(x=x) 7 xf$x[10] = 1 8

I''m trying to add some per-object behaviors to objects descended from ActiveRecord, by using after_initialize() and instance_eval(), like this: def after_initialize self.instance_eval(File.read(''customers/default.rb'')) end (Ultimately the file path will be dynamic, this is just proof of concept.) default.rb just contains a few method definitions like this one: def

Hi All, i have a problem in understanding what the assignment operator '<-' really is doing. If i create two numeric arrays in R and copy one into the other with '<-' and afterwards change one array by calling a C function, both arrays are changed! The problem I am facing can easily be seen in the following example: (The following R code and the C function is attached and

Some experimentation with the below function should convince you that the runtime of the bit inside sys.time is proportional to size*number*times. I think it should only be proportional to number*times. The function is only manipulating a list of references to vectors and not trying to make changes to the vectors themselves. overcopying <- function(size, number, times) { #Make a list of

I have models with large TEXT, BLOB columns and I don''t wanna fetch them everytime. Is it possible to omit columns when fetching records from DB? Sorry, if it''s trivial, but I can''t find helpful information in docs.

Hi It seems that selecting an element of a factor will copy its levels (Ubuntu 13.04, R 3.0.2). Below is the output of a script that creates a factor with 10000 elements and then calls as.list() on it. The new object seems to use more than 700 MB, and inspection of the levels of the individual elements of the list suggest that they are distinct objects. Perhaps some performance gain could

Hello, I'm introducing to you the decentralized cloud Cherrypop. Combining libvirt and LizardFS (as of now) it becomes a cloud completely without masters. Thus, any node is sufficient for the cloud to be up and therefore no wasted resources and no single point of failure. It's still pretty crude software but will work with some tinkering. Hope you try it and like it! For more
