The script sends a batch of emails (currently 100), waits a bit (currently 25 seconds), and then sends another batch.
When we first set this up it ran perfectly. We do a mailing every week or two, and after a few mailings we started getting very high server loads as reported by WHM. We have a dual core machine, so the server load should never go over 2. At one point, after the script had been running unattended for several hours, it was 5000! Memory usage was also up to over 97%.
We cut the batch size, increased the delay, but we still have to monitor the mailing constantly. We went in with top to see what was happening but the only thing we could tell for certain was that sendmail was basically taking over the server.
I don't have a lot of experience with Linux. If this was Windows I'd look for disc fragmentation, but I think Linux is not subject to that kind of problem. The mailing list includes over 400,000 names. When we first started using the script there were no problems, and the problems seem to be getting worse over time.
Any ideas as to what the problem might be or a way to fix it? | linux | script | sendmail | null | null | 02/12/2012 23:27:47 | off topic | Overloads with sendmail on Linux server

The system uses one big database ordered by longitude, when a player joins, their current longitude is written to the database. The reason for this is so that the database can quickly be polled for other nearby players.
Not really understanding that much about databases I was wondering the best structure to use to achieve this. I want to avoid larger re-ordering rewrites when players join so I'm going to make the database prior to the game launching and create blank spaces for every value of longitude, however it dawned in me that I may need multiple slots for each value due to more than one player being at the same location - this doesn't scale well at all.
What would be the best structure to achieve this? Perhaps player id's that index into another database storing information? | database | null | null | null | null | 04/30/2012 15:56:14 | not a real question | appropriate database structure for a location based game

I would like to be able to define certain properties in the ES5 style: `prop: { value: '1', enumerable: false, writable: true }`, but there's a hitch.
First, JSON.parse() simply interprets the 'enumerable' and 'writable' properties as generic properties on a generic JavaScript object. This is probably expected and desirable behavior, but is the a comparable method to 'parse' the JSON with respect to new ES5 property attributes?
Second, Object.create() works, but it has some limitations. For example,
//Native works
var prop = Object.create(Object.prototype, { prop: { value: '1', enumerable: false, writable: true } });
//prop === "1"
//Parse works
var prop = Object.create(Object.prototype, JSON.parse({ "prop": { "value": '1', "enumerable": false, "writable": true } });
//prop === "1"
//Parse fails
var prop = Object.create(Object.prototype, JSON.parse({ "prop": { "value": '1', "enumerable": "false", "writable": "true" } });
// prop === JSON.parse({ "prop": { "value": '1', "enumerable": "false", "writable": "true" } })
The problem here, of course, is that `"true" !== true`, which instructs `Object.create()` to return the same object as `JSON.parse()`. Further, either because of the truthy evaluation of a particular prop attribute OR because I'm attempting to create particularly large objects, `Object.create()` seems to be quite fragile.
Is there a better way to "parse" these objects in a way that respects the ES5 prop attributes?

===
[In my client/server web app][1], I am generating large JSON strings (using JSON.NET JToken classes in C# web services) which I pass via AJAX Get requests to the client.
I would like to be able to define certain properties in the ES5 style: `prop: { value: '1', enumerable: false, writable: true }`, but there's a hitch.
First, JSON.parse() simply interprets the 'enumerable' and 'writable' properties as generic properties on a generic JavaScript object. This is probably expected and desirable behavior, but is the a comparable method to 'parse' the JSON with respect to new ES5 property attributes?
Second, Object.create() works, but it has some limitations. For example,
//Native works
var prop = Object.create(Object.prototype, { prop: { value: '1', enumerable: false, writable: true } });
//prop === "1"
//Parse works
var prop = Object.create(Object.prototype, JSON.parse({ "prop": { "value": '1', "enumerable": false, "writable": true } });
//prop === "1"
//Parse fails
var prop = Object.create(Object.prototype, JSON.parse({ "prop": { "value": '1', "enumerable": "false", "writable": "true" } });
// prop === JSON.parse({ "prop": { "value": '1', "enumerable": "false", "writable": "true" } })

I and my team was told to do some documentation as we are working on the project. It is made in c# .net and we are using Visual Studio 2010 for this. I have never documented any project so far and have no idea where to start. Can someone guide me to some tips for this like what all things need to be noted down and how should I proceed? Its a pretty huge project and we will be working on small areas of it and need to document it. On google I have come across some documentation software as well but I suspect that I can use it here. Any good documentation article for beginners will also work fine for me.

I was originally using a XAMPP server on my PPC Mac running OS X 10.4 Tiger, but it didn't have the ssl support that I needed.

By compiling from the source, I have installed an Apache server (2.2), the imap extension for php, and the openssl extension for php. (Though I don't know if that's needed.)

The argument was over the operator override. My co-worker feels that it's not best programming practice to set values of private fields anywhere but the constructor. The solution proposed by my co-worker was to refactor the name of the `Stuff` property to `AllStuff` and add a property, `Stuff`, that has a `get` AND `set` accessor and use the new `Stuff` property in the operator override.

I disagree. I feel the first way is better since it keeps the property read-only outside the class. My question is, which way is the best practice for object-oriented design? | c# | null | null | null | null | null | open | Should I use a Field or Property within the class to set values

![Problem][1]
My lower level is a drop-shadow in this case. Because I assumed the drop shadow would be attached to the main element (a Button), I created another visual element, a Border, which sits behind the Button and has the shadow attached. What I would like is for all of my shadow elements to be at the same overall ZIndex, and all of the Button elements to be above them.
In practice, it appears that WPF renders the contents of my template as a single UI element, essentially flattening the ZIndexes within it. Is there any way I can make it so that the ZIndex values are not flattened?

I'm not really used to newer architectures that superseded old TLA (three layer architecture), so that's where I'm coming from.
When designing the *Model* and the *DAL* for my application (POCO classes, right??), I got the following doubts:
1. **Should my Model classes only expose properties and implement rule validations?** A few years ago I'd implement classes that were analogous to the real world, so if I had a *Person* who could *Walk*, I'd create such a method. Now, every sample I check (MVC, MVVM, etc.) have "dumb classes", which expose data and, when required, validate those data. What about complex operations? Should they become, somehow, part of the VM (I doubt this is right...).
2. **When using LINQ to SQL as an ORM mapper, should I expose in the model all the attributes of the entity?** For example, most of my entities have an ID column as its primary key. This should be of no concern of the Model or Business, just an implementation detail of my database schema.
3. **If (1) and (2) are false, so the Model *should* expose complex operations on the classes and not all of the entities attributes should be exposed, how do I create the Model classes using LINQ to SQL and sqlmetal?** I've seen some samples that use partial classes to extend the functionality of the schema entities, but that would result in exposing the entity details (since it's just an extension).
3. **If (2) is false, what is the most correct way of using sqlmetal and LINQ as an ORM?** I use sqlmetal to extract the schema, LINQ to select entities, and then what? Create new entities based on what I have on the database?
4. **In my researches I found that the VM from MVVM and the P from MVP are somewhat similar. What are the responsibilities of a *Presenter*? And those of a *ViewModel*?** I'm focusing on those two patterns because they completely isolate the View from the Model, an aspect that I prefer.
5. **What are some methodologies when designing such [MVVM, MVP] applications?** Should I begin thinking about the Model, then the {P, VM} layer, then the view? This is more of a subjective question, I know, but examples would be nice.
*I hope I was able to make the questions objective enough. I've added explanations to my doubts in order to simplify answering, but I'm afraid this has made the post a little bit too large.

What I want in my game is the availability of a few "prebaked" levels that come installed with the game but also the ability for users to create their OWN levels.
So what I did is created a new directory inside visual studio in the "Content" called levels, and put a "level1.txt" there. But the only way I can access the level *.txt files is by using full path, and I cannot INCLUDE them in my visual studio solution because it does not build:
"C:\My Documents\blahblabh....\levels\level1.txt"
- Do I put these "prebaked" maps instead into some directory near the executable? How do I create a directory inside the /bin directory Before I compile the project?
- How do I dissalow users from deleting the "prebaked" levels that come installed with the game?
- Also, Where do I store the User Custom created levels? I assume that should be done with StorageDevice. But that ties in with the first question on how to create a directory after game is deployed.

I have been looking at ASP.NET4 in terms of books and theoretical knowledge, and that is the world of JSONs and AJAX (looks like repeaters are from an older world)- so everything that I learn in context of ASP.NET4 is not applicable directly to my environment (I do use JSONs/AJAX etc lightly).
This is not the typical code request that we see in the forum and I am sorry if my post is out of the norm. However, this is a great forum with knowledgeable members and I am a frequent visitor- so I though I would ask this basic question anyway. Any suggestions(and/or clarifications on contents of ASP.NET 1-4) are very welcome.
Thanks,
K.

Ex: A=[1 1 2 4]; B=[1 2 4];
Desired result would be A-B=C=[1]
Or, another example, E=[3 3 5 5]; F=[3 3 5];
Desired result would be E-F=G=[5]
I wish I could do this using Matlab's set operations, but their function setdiff does not respect the repeated elements in the matrices. I appreciate that this is correct from a strict set theory standpoint, but would nevertheless like to tackle problems like: "I have 3 apples and 4 oranges, and you take 2 apples and 1 orange, how many of each do I have left." My range of possible values in these sets is in the thousands, so building a large matrix for tallying elements and then subtracting matrices does not seem feasible for speed reasons. I will have to do thousands of these calculations with thousands of set elements during a gui menu operation.
Example of what I would like to avoid for tackling the second example above:
E=[0 0 2 0 2]; F=[0 0 2 0 1];
G=E-F=[0 0 0 0 1];

import matplotlib as mpl
AXES_COLOR = '#333333'
mpl.rc('axes', edgecolor=AXES_COLOR, labelcolor=AXES_COLOR, grid=True)
mpl.rc('xtick', color=AXES_COLOR)
mpl.rc('ytick', color=AXES_COLOR)
mpl.rc('grid', color=AXES_COLOR)
The color of the axes labels and the ticks are properly set both in 2D and in 3D. However, the `edgecolor` doesn't apply to 3D axes and they remain black. Likewise, the grid isn't affected.
I think figured out how to access the individual axes of a 3D plot:
import matplotlib.pyplot as plt
import mpl_toolkits.mplot3d # Needed for 3d projection.
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.w_zaxis # <- the z axis
The [documentation][1] mentions a property that we can use until the developers have finished refactoring their 3D code:
import pprint
pprint.pprint(ax.w_xaxis._AXINFO)
{'x': {'color': (0.95, 0.95, 0.95, 0.5),
'i': 0,
'juggled': (1, 0, 2),
'tickdir': 1},
'y': {'color': (0.9, 0.9, 0.9, 0.5),
'i': 1,
'juggled': (0, 1, 2),

'z': {'color': (0.925, 0.925, 0.925, 0.5),
'i': 2,
'juggled': (0, 2, 1),
'tickdir': 0}}
However, the color parameter changes the color of the background of the axes planes (between the wired of the grid), not the color of the edges of these planes.
Am I digging too deep ?

jQuery(document).ready(function() {
jQuery('.more_info').each(function(){
jQuery(this).tooltip({
effect: 'slide',
offset: [10, 570],
predelay: 100,
position: "bottom left"}).dynamic( {
bottom: {
direction: 'down',
bounce: true
}
});
});
});
after ajax is loaded , tooltips not working any more because , script already was loaded , i tried solution from forum http://flowplayer.org/tools/forum/30/37281 , but is not working , or is not implemented correctly
here is code :
jQuery(document).ready(function() {
jQuery('.more_info').each(function(){
jQuery(this).not('.tt_init').tooltip({
effect: 'slide',
offset: [10, 570],
predelay: 100,
position: "bottom left"}).dynamic( {
bottom: {
direction: 'down',
bounce: true
}
});
jQuery(this).not('.tt_init').addClass('tt_init');
});
});
and nothing ... I'm doing something wrong , Thank you for helping ;) , sorry for my bad English | 0 |

The code each time switches 'off' and 'on' the devices to which it is communicating, then initializes the three com ports, tries to send and read data and then closes the com port. This keeps continuing for a pre-defined number of loops.
My problem is that after about 8 or 9 iterations, the COM port communication stops working. Sometime it throws an error saying the port is closed, sometime it does not throw any exception but it is actually not reading or writing anything from the com port. Some point it was only writing but not reading back the data.
What might be the reason and any tips to debug this problem?

There is a recomendation to use Excel to have this view (i.e each row is a initiative/task/project at a highlevel, each cell being the day and the value in the cell is the effort required). However, working on MS Project (to manage project) I've found that this is a better alternative than excel, purely since it is easier to manage in the future.
I wanted:
A) Get your views on excel vs ms project
B) On how to get a view of MS Project of daily utilisation, and easy editing (i.e not having to switch back and forth from views)
C) any other methods...

There is a recomendation to use Excel to have this view (i.e each row is a initiative/task/project at a highlevel, each cell being the day and the value in the cell is the effort required). However, working on MS Project (to manage project) I've found that this is a better alternative than excel, purely since it is easier to manage in the future.
I wanted:
A) Get your views on excel vs ms project
B) On how to get a view of MS Project of daily utilisation, and easy editing (i.e not having to switch back and forth from views)
C) any other methods...

As I see it you would still lose just as many significant bits while shifting. | floating-point | precision | floating-accuracy | accuracy | numerical-analysis | null | open | Addition vs Subtraction in loss of significance with floating-points

resources :cars do
resources :owners
end
and then a custom route -
match "/:cars" =>"cars#edit", :as => :car
This works - if a user visits mydomain.com/somecarname - it takes them to the edit action of the cars controller.
The problem occurs when I edit that car and hit save -
I get redirected to mydomain.com/1 (or whatever id the car is) - I presume this is the show action.
and get the following error -
undefined method `owner' for nil:NilClass
how do I set up it up to work correctly?
