Originally posted on github, reported to the right place. I would like to open a discussion about how `to_json` and `as_json` operates in Rails from a performance standpoint. I''m using Rails 3.2 but this issue applies to almost all versions of Rails. Our use case presents the challenge in sending out potentially large JSON (or XML, but we''ll focus on JSON rendering here)

Hi, To generate random numbers between 0 and 1, do you use rnorm followed by dnrom? for ex, for 10 variables a = rnorm(10) > a [1] -0.87640764 -0.95842391 -1.33434559 -0.63844932 -1.69829393 0.80010865 [7] -0.01026882 -0.23887516 2.29912600 -1.38352143 > dnorm(a) [1] 0.27171985 0.25202507 0.16378878 0.32538464 0.09432211 0.28966637 [7] 0.39892125 0.38772103 0.02838403 0.15320103

I sent a message a couple days ago about doing calculations for power of the ANOVA. Several people got back to me very quickly which I really appreciated. I'm working now on a similar problem, but instead of a balanced ANOVA, I have an unbalanced one. The first part of the question was: You assume that the within-population standard deviations all equal 9. You set the Type 1 error rate at á

The "hide unreadable = yes" option gives strange results with samba 3.x. Everything works fine when the server runs as a domain controller. Users see the directories they are supposed to (unix group permission) in the share. Turning off domain control and setting "security = DOMAIN", however, hides every directory in the share unless you are an admin user. I can cd to the

After upgrading XP to SP2, I can no longer connect to server aliases. The client reports an error 53, "The network path was not found", when doing "net use * \\prof\profile. Mapping to a share on the real netbios name works fine. Anyone else seen this? Setup: samba-3.0.6.rc2 smb.conf [global] netbios aliases = PROF include = /etc/samba/smb.%L smb.prof [profile] path =

Hi I'm trying to get the rebuilt parking functionality to work in Asterisk 12.0.0. In Asterisk 11.6.0 I managed to get a call to get parked by adding a dynamic feature in features.conf for the DMTF sequence *# which called a macro in extensions.conf, which then runned the ParkAndAnnounce application, and the call got parked. The syntax for ParkAndAnnounce I used was this (I don't

Hi, I am new to R. and even though I've made my code to run and do what it needs to . It is taking forever and I can't use it like this. I was wondering if you could help me find ways to fix the code to run faster. Here are my codes.. the data set is a bunch of 0s and 1s in a data.frame. What I am doing is this. I pick a column and make up a new column Y with values associated with that

Hi everyone ! Please have a look below : [Image: http://designed2.free.fr/forums/winescreen.png ] This box should show my personal folders, currently obviously don't display right now [Shocked] I think I have others things like these, some texts I can't see in some particular windows (emule.exe for example: texts in connection log won't show up). I'm certainly missing something in

Here is a letter I sent them for my $150 paper weight. Dear Voipsupply, As a small service provider, using you company for the first time, I'm very disappointed that you have removed the configuration CD that should have been shipped with the Mediatrix 2102 just to get a few more bucks. I have contacted mediatrix and they have informed me that the CD's is shipped in every 2102. If I

Hello all, I just installed chan_h323 by Jeremy (nufone) with asterisk-head. well, I have some questions if someone please briefly answer. 1 - can we configure h323 to work in g729 pass-thru mode, like we do in SIP. becaz I had to installed g729+intel libraries to work with g729. where as we don't need to install g729 to work in pass-thru mode. 2 - now most important question is

Hi, I'd like to plot in in polar coordinates a line which is given as a vector of lengths and angles. library("plotrix")

When you create a parser via ANTLR you specify the output language of the resulting recursive descent parser, at the moment there exists no C++ output template to my knowledge, thus you would have to generate the parser as C code for which a template exists. The runtime support should be there, at least partially but it won't use things like exceptions, nor will it have a very modular design

That sounds like a problem. Just so I understand, do you mean there isn't the run-time support etc. to write back ends for the C++ language, or that the compiler IR is also somehow insufficient to write a code generator? --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Jul 11, 2009, at 3:00 PM, Granville Barnett
