Good day all. I have successfully installed Engines and LoginEngine and LE is setup and running correctly. However, after installing and setting up UE, when attempting to run the rake bootstrap method I get the following error: undefined method `synchronize_with_controllers'' for Permission:Class My environment is Rails 1.0.0 Ruby 1.8.2 WinXP WebBRICK MySQL 4.1.14 I found the following

Hello! I''m pretty new to unit testing, and have only been using RSpec for a few weeks. I found that for my controller specs, my setup methods were getting very long building mocks/stubs for all the model objects I needed to work with. I''ve started creating helpers like the following for each of my models. The "min_" methods are short for "minimum", and

Good day all. This is one of the most frustrating days I have had with Rails in quite some time now (almost 8 months actually). Yesterday I complete my development and testing and everything is peachy. I head home for the evening and do my things there. This morning, I come back in and do my typical morning routine of starting up eclipse and the usual "ruby script/server" command in

Hi, I use link_to_remote to create a link to trigger an ajax, things work fine, a new rhtml is created, however, the newly created rhtml doesn''t replace my old zone, it shows instead on top of my old zone...Does someone know why??? my code is like <table> <tr><td colspan="2"><a href="#" onclick="new Ajax.Updater(''zone1'',

Well, I did finally get the after_update_element to call my controller action with the following syntax: <%= text_field_with_auto_complete ( :customer, :company_name, { :size => "45" }, :after_update_element => "function(element,value){" + remote_function( :url => { :action => :get_customer_info }, :with =>

The current libxl_set_memory_target function subtracts a negative amount from an uint32_t variable without checking if the operation wraps around.

I am just beginning to learn R. Please help. I have two matrices. One 20 columns by 16 rows represent student responses on a 20 question test. The second is 20 by 16 representing the correct responses 16 times. Subtracting one from the other should yield 0's if a response is correct. Yet Response minus Bigkey doesn't work. Documents indicate vectors should add and subtract, and

I was working on a teaching example, but came across this weird result: > q<-c(1.6,2.6, -3.4) > q [1] 1.6 2.6 -3.4 > sum(q) [1] 0.8 > sum(q)- 0.8 [1] 2.22044605e-16 Why is the result not precisely zero? Thanks! AT

I don't know if there is a way to do this in R but I want to subtract within the same column from different rows. I want to subtract c(r)-c(r-1) and continue down the column until they are all calculated and form another column. Again I don't know if R can do this but I thought I would ask. Thanks either way

I have a data frame with 2 columns, one for day and one for average. The day starts at 97 all the way to 279. I want to subtract day 98 average- day 97 average, then day99 average -day 98 average and so on down my list, creating another column with the subtracted results. I have: Day DailyAverage 1 97 0.6076782 2 98 0.7121478 3 99 0.8059347 4 100 0.9545806 5

I would like to calculate vector from existing value e.g v <- 1000 s <- 30 d1 <- v-s d1 <- 970 d2 <- d1 -s d2 <- 940 d 3 <- d2-s d3 <- 910 : : d15 <- ..... so how I should get vector of length 15 d < - 970,940 , 910 , ....... -- View this message in context:

https://bugzilla.mindrot.org/show_bug.cgi?id=3732 Bug ID: 3732 Summary: An integer underflow may occur due to arithmetic operation (unsigned subtraction) between values '0' and '67108864', where the first value comes from the expression 'h4 + b' and the second value comes from

OK, this is very elementary, but I need help. I have looked in Verzani, past postings etc. Problem: I need to subtract the "length" date between "h4" and "a3" #which would be 4-1 I would rather not convert the two columns into four columns (with headings being "a3","a4","c4","h4"). DF <- data.frame(length=c(1,2,3,4),

Hello, I have a vector (numeric) v-> c(a,b,c,d,e) and I want to create the vector n->c(b-a,c-b,d-c,e-d). How can I do that? Thank you Hermann [[alternative HTML version deleted]]

hello, today while trying to extract data from a list for subsequent analysis, i stumbled upon this funny behavior on my system: > x<-c(0.1,0.9) > 1-x[2] [1] 0.1 > x[1] [1] 0.1 > x[1]==1-x[2] [1] FALSE > x[1]>1-x[2] [1] TRUE > x<-c(0.3,0.7) > x[1] [1] 0.3 > x[2] [1] 0.7 > 1-x[2] [1] 0.3 > x[1]==1-x[2] [1] FALSE but: >

Hi all, This is my first ever post, so forgive me and let me know if my etiquette is less than that required. I am searching for a faster way of subracting group means within a data frame than the solution I've found so far, using AGGREGATE and MERGE. I'll flesh my question out using a trivial example: I have a data frame Z with two columns - one X of values and one Y of labels: > Z

Hi all, I am writing a custom backend. Doing more testing i notice that for some reason something like: int test(int x) { return x - 1; } is being turned into this IR: ; Function Attrs: nounwind define i32 @test(i32 %n) #0 { entry: %n.addr = alloca i32, align 4 store i32 %n, i32* %n.addr, align 4 %0 = load i32* %n.addr, align 4 %sub = sub nsw i32 %0, 1 ret i32 %sub } But finally in

Hi, This message is a result of a discussion of backend optimization for sub(max) pattern(https://reviews.llvm.org/D25987), which can be either converted to unsigned min-max or unsigned saturation instruction(if the target supports it). Currently these versions of the code produce different IR(and we need to manage both types in backend): (1.16) void foo(unsigned short *p, unsigned short max,
