- Have been away from RoR development for a couple of years. - Will be doing a new project soon, starting with RoR 3.1. - This site will be hosted on a dedicated user-controlled server inside their intranet, so this question is not about hosting services. - Expect about 100,000 page views a day, with a bit more spikiness than normal around some shift changes, so provisioning as if for 500,000

hi, i have a app which has a spiky activity, there a large period of inactivity between request. With phusion-passenger after a period of inactivity the process is killed, and when the app is respawned the ''show status'' queries take more time than the actual sql themself. I know that ActiveRecord makes the '...

Hello, I could not yet create combined graph in R. To avoid misunderstands, three examples (originally created in Quattro pro) have been attached. At first, I don't know how to create graph composed of bars and areas in the same picture as it is shown in the balance graph (h2plc02.gif). I am sendind the original data table from that I need make the same charts. First column (julian day)

Hi the list, I use rgl to produce a 3D graph. I would like to "show" this graph to some collaborator. Is there a way to save it and send it to someone else? Christophe Genolini

Hello I''ve started working through the book "Agile web development with Rails" and so far everything has been great. I''m on page 56, 57 trying to create the admin tool for the example project "Depot". I''m on OS X Panther 10.3.9. I have checked the Errata on the website and tried some of the suggestions there, but nothing has worked. When I

Hi, I know some of you are very experienced as to the working of networks. I wondered whether there is some accepted way of determining bandwidth needs based on the network traffic over time. For example, looking at the figures for the network traffic through the server interface, we have hourly, daily and monthly figures. If everything were linear, taking the hourly figure and dividing it by

...be sure (I already have a Haar wavelet implementation that build a binary tree, and then saves the coefficients walking the tree breadth-first, which yields the last format). What I hope to do is do a wavelet-transform of each frame. If I understand correctly this should yield a rather "spiky" "graph", due to the characteristics of the data. Now I want to encode the difference in location and amplitude of these spikes in a smooth curve. Ofcourse this only works well if the changes happen to lie on a curve, so I'll have some staring to graphs to do. Anyway, if the...

...e bread and butter for obtaining server-quality hardware. The typical donation will be at least one or two generations old before the non-profit gets it; my current employer is just putting in production some IBM BladeCenters with the dual-socket Opteron LS20 blades (10+ years old). Given the spiky workload, these blades are suitable for the targeted use, and the electrical requirements aren't a problem (I've done the math; it would take ten years or more to justify the purchase price of a new blade based on power savings alone, and our power is quite inexpensive here). At least...

Hi, I am having some problems mentioned below, the box is in production live environment with traffic around 30 - 100 calls. I am running T/E410P in a Dual P4 xeon with HT disabled. I am using zaptel 0.9.0 and asterisk stable 1 release. There is no gui, just mysql, perl (small script) and asterisk. System runs very smoothly if the calls are around 40-50 and comes one by one , however sometimes

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML
