• PHP4 No Error When Missing Method is Called

  - by INTPnerd

  I have come across an annoying problem while writing some PHP4 code. I renamed the method of a class but I forgot to rename it where it was being called from. The annoying part is it was hard to track down where the problem was because no error was triggered. The script simply aborted leaving the web page partially rendered. Is it normal for this not to trigger an error or is there something wacky going on here? If this is normal is there a way to force this kind of thing to cause an error?

• Recognizing file - Python

  - by Francisco Aleixo

  Ok, so the title may trick you a bit, and I'm sorry for that but didn't find a better title. This question might be a bit hard to understand so I'll try my best. I have no idea how this works or if it is even possible but what I want to do is for example create a file type (lets imagine .test (in which a random file name would be random.test)). Now before I continue, its obviously easy to do this using for example: filename = "random.test" file = open(filename, 'w') file.write("some text here") But now what I would like to know is if it is possible to write the file .test so if I set it to open with a wxPython program, it recognizes it and for example opens up a Message Dialog automatically. I'm sorry if I'm being vague and in case you don't understand, let me know so I can try my best to explain you.

• tomcat 6 - Cluster / BackupManager

  - by Kevin

  Hi, I have a question regarding Clustering (session replication/failover) in tomcat 6 using BackupManager. Reason I chose BackupManager, is because it replicates the session to only one other server. I am going to run through the example below to try and explain my question. I have 6 nodes setup in a tomcat 6 cluster with BackupManager. The front end is one Apache server using mod_jk with sticky session enabled Each node has 1 session each. node1 has a session from client1 node2 has a session from client2 .. .. Now lets say node1 goes down ; assuming node2 is the backup, node2 now has two sessions (for client2 and client1) The next time client1 makes a request, what exactly happens ? Does Apache "know" that node1 is down and does it send the request directly to node2 ? =OR= does it try each of the 6 instances and find out the hard way who the backup is ?

• Django Comments and Users integration

  - by Patrick

  Hi folks, I am new to django. I am trying to use django.contrib.comments, I saw the table in the database like this, but how can I integrate it with user_id, user_photos, user_name, user_email....and those things with the django commenting system? I also tried to use thread-comments, but I can't configure it properly, is the django threadedcomments table similar to following ? Please let me know if any of you have done this before....all I need is a user login, and post comments, and then show list of comments with users' profile photos and username, as well as there comments. I think shouldn't be that hard.

• virtualenv on Windows: not over-riding installed package

  - by Tom

  My current setup is Python 2.5/ Django 1.1.1 on Windows. I want to start using Django 1.2 on some projects, but can't use it for everything. Which is just the sort of thing I've got virtualenv for. However, I'm running into a problem I've never encountered and it's hard to Google for: installing Django 1.2 into a virtualenv has no effect for me. If I then activate the environment and do python import django django.VERSION I get "1.1.1 Final". Django is installed in the site-packages directory of my environment and the init file in the root shows that it is 1.2. But the environment falls back to 1.1.1, even if I create the environment with the --no-site-packages flag. What am I screwing up?

• SqlBulkCopy unusual TimeOut Error

  - by ChrisHDog

  I have a SqlBulkCopy operation that is taking data from an MS-Access 2007 database (via OleDbConnection) and using SqlBulkCopy to transfer that data to a SQL Server database. This has previously been working and continues to work for one MS-Access database, but not the other. I get the error message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It is hard to believe it is a timeout ast the oledbCommand.CommandTimeout = 0 the sqlBulkCopy.BulkCopyTimeout = 0 and on either side (MS-Access and SQL Server the timeouts have now been set to 0). Are there other issues/exceptions that the above error message could be hiding? Is there a way to determine what the base cause of a sqlBulkCopy.WriteToServer exception is (there doesn't appear to be any inner exceptions etc...)

• Simple XML parsing with Google Picasa API and JQuery

  - by zeedog

  I'm starting to look into Google's Picasa API for photo data, which provides you with a big XML file with info about albums and photos. I'm doing some quick and dirty tests to parse the XML file (which is saved locally to my hard drive for now) with JQuery and pull out the album id's, which are stored as "gphoto:id" tags, and display them in a div: $(document).ready(function() { $.get( 'albums.xml', function(data) { $(data).find('entry').each(function() { var albumId = $(this).children('gphoto:id').text(); $('#photos').append(albumId + '<br />'); }) }) }) I'm getting the following error in the console: jquery.js:3321 - Uncaught Syntax error, unrecognized expression: Syntax error, unrecognized expression: id This will work with other tags in the XML file (such as title, author, updated, etc.), but I'm trying to understand what's going on here. Does it have to do with the colon in "gphoto:id", somehow?

• 2-way anova on unbalanced dataset

  - by mortalitysequence

  Is aov appropriate for unbalanced datasets. According to help ...provides a wrapper to lm for fitting linear models to balanced or unbalanced experimental designs. But later on it says aov is designed for balanced designs, and the results can be hard to interpret without balance. How should I perform a 2-way anova on an unbalanced dataset in R? I would like to reproduce the different results for type I and type III sum of squares of SAS output (when using proc glm). I remember we were using type III sum of squares for unbalanced datasets. Thank you in advance.

• ASP.NET: CSS friendly calendar control

  - by pbz

  I'm using the built-in Calendar control. It works, but in a few places the way the HTML is rendered is broken or not CSS-friendly and unfortunately cannot be changed (it's hard coded). I was hoping they would fix this in .NET 4.0, but as far as I can tell the Calendar control hasn't been changed at all. Also, as far as I know, there's no CSS adapter for the Calendar control. So, I would need a control that would: Allow me to customize the content of each cell (like OnDayRender works) Allow me to assign CSS classes to any HTML it may render Not render anything automatically that cannot be turned off, except layout code No auto-postback or auto-JS code (I can handle these by hand using simple links or custom JS calls) Basically a simple calendar view control that would give me full rendering control. What would you recommend? Thanks!

• How can I tell NetBeans to use the latest available version of a JAR for a library?

  - by Freiheit

  I have a Netbeans project with a library defined which includes several JARs. These JARs are versioned like lib\blah\com.blah.wibble.jar_0.6.1.201004161543 . These are nightly builds from another project so that version changes often. I know I can point NetBeans at the specific JARs with the version name, but this means that every time I get a new version I have to update the NetBeans library. I can also strip the version name from the JARs, but this makes it hard to track down bugs. "What version of the blah JARs?" is usually the second thing we ask when we find a bug. Is it possible to tell Netbeans to use included com.blah.wibble.jar_[??????] where ???? is some sort of automatic pointer to use the latest available version?

• Entity Framework VS LINQ to SQL VS ADO.NET with stored procedures?

  - by BritishDeveloper

  How would you rate each of them in terms of: Performance Speed of development Neat, intuitive, maintainable code Flexibility Overall I like my SQL and so have always been a die-hard fan of ADO.NET and stored procedures but I recently had a play with Linq to SQL and was blown away by how quickly I was writing out my DataAccess layer and have decided to spend some time really understanding either Linq to SQL or EF... or neither? I just want to check, that there isn't a great flaw in any of these technologies that would render my research time useless. E.g. performance is terrible, it's cool for simple apps but can only take you so far

• R: ca plotting text attributes

  - by chasec

  Does anyone know of a way to control the font size/color/weight of the row and column names when plotting a correspondence plot with the ca package? The following code will produce a very nice looking chart, though if there were more attributes (very heavy, super heavy, something more than super heavy) or more classes of workers (peons, underlings, etc) then the graph will get a little cluttered and hard to tell what was what. It would be nice if you could list all the attributes in a separate color than the categories of workers. library(ca) data("smoke") plot(ca(smoke) , map = "symmetric" , what =c("active","active") , mass = c(T,T) , contrib = "absolute" , col = c("red","blue") , pch = c(15,17,15,17) , labels = c(2,2) , arrows = c(T,F) ) Alternatively, does anyone know if there is a way to reproduce something along these lines with ggplot2? I didn't find anything on the website that seemed comparable, but I don't know much about the package. Thanks, -Chase

• How can I show SQL Server LOGS (2005)

  - by Marcin Rybacki

  Hello, I'm trying to track the error thrown by SQL Server 2005. The problem is SQL Server reports it in my native language so it's hard for me to google it. I think that the core issue would be avialable in English in SQL Server LOGS. I'm running SQL Server Management Studio Express, going to "Management" node, and then SQL Server Logs. I can see the list of logs but I cannot enter them, the only available option in context menu is Refresh. Could you help me to show the contents of those logs?

• How can I separate Logic/UI in Android

  - by Ungureanu Liviu

  Hi, I want as my application to be structured in 2 parts: the logic code and the UI. I've tried to implement that using a controller class(here I keep the logic code) inside of each activity. The activity send messages to controller and receive the answer in two ways: the answer is returned immediately (if the action is not complex and it can be done in a verry short time) the activity set some listeners and the controller fire this listener when the action is complete. The problems appears when the controller have a lot of objects(each object should handle a set of actions and for each action I have to set & trigger a listener): it is hard to keep the code syncronized. I'm asking if you know a better way to implement this mechanism. Thank you.

• Open source configuration framework for ASP.NET - does one exist?

  - by Jon

  We currently have an old product written in classic asp and are about to re-write parts in ASP.NET. One big problem is that much of the cutomer-specifics within the system are hard coded. We want to split this out for specific customers by storing data in the database. Is there a quick an easy open source framework which allows me to set up some quick tables and simple UIs to allow me to change configuration items? We have 6-7 modules, and it would be nice to have the ability to have system admins gain access to a configuration area where they can set-up settings in a tabbed UI format, settings could also be set-up to allow dropdown, fields, numbers etc. The items could then be accessed via classes in C#/vb for use within the operational parts of the system. If not, I'm suprised and it might even be a good basis for a new open source project.

• Advice on e-commerce logging strategy

  - by yalestar

  I recently inherited an e-commerce app (Java/Struts) that I'm porting to Rails. The thing is, we frequently have to do forensics on orders by poring through the log files, and with the old app's logs (log4j wall of text) it's pretty hard to make sense of the individual orders when several people are placing orders simultaneously. So I'm soliciting advice on a good strategy for logging of these orders, like maybe logging each individual order to its own MongoDB collection based on unique cart ID? Or maybe group them by IP address? Something different entirely? Essentially, what is the best approach for logging of an online store so that it's easy to backtrace each user's interaction with the site?

• How Can I Generate Random Unqiue Numbers in C#

  - by peace

  public int GenPurchaseOrderNum() { Random random = new Random(); _uniqueNum = random.Next(13287, 21439); return UniqueNum; } I removed unique constraint from the PONumber column in the db because an employee should only generate P.O. # when the deal is set. Otherwise, P.O. # would have 0. P.O. Number used to have unique constraint, this forces employee to generate P.O. in all cases so the db doesn't throw unique constraint error. Since i removed the unique constraint, any quote doesn't have P.O. will carry 0 value. Otherwise, a unique value is generated for P.O. #. However, i don't have a unique constraint in db which makes it hard for me to know whether the application generated P.O. # is unique or not. What should i do? I hope my question is clear enough

• bash: hwo to know NUM option in grep -A -B "on the fly" ?

  - by Michael Mao

  Hello everyone: I am trying to analyze my agent results from a collection of 20 txt files here. If you wonder about the background info, please go see my page, what I am doing here is just one step. Basically I would like to take only my agent's result out of the messy context, so I've got this command for a single file: cat run15.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' This means : after the regex match, continue forward by 50 lines, stop, then match a line separator starts with "==", go back by 50 lines, if possible (This would certainly clash the very first line). This approach depends on the fact that the hard-coded line number counter 50, would be just fine to get exactly one line separator. And this would not work if I do the following code: cat run*.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' The output would be a mess... My question is: how to make sure grep knows exactly when to stop going forward, and when to stop getting backward? Any suggestion or hint is much appreciated.

• Create Out-Of-Process COM in C#/.Net ?

  - by Huck

  Hi, I need to create an out-of-process COM server (.exe) in C# that will be accessed by multiple other processes on the same box. The component has to be a single process because it will cache the information it provides to its consumers in memory. Note: the processes that will access my COM Server are mostly Matlab processes, thus the necessity for a COM interface. I have seen threads regarding creating in-process COM components in .Net on stack overflow (Create COM ...) and on the web, but am having a hard time to find a way to create out-of-process components with .Net. How is this achievable? Any suggested references? Thanks.

• Android WebView not respecting scaling percentage...

  - by fiXedd

  I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag: <meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1"> Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%. Ideas?

• Delphi Typed Constants in Case Statements

  - by Andreas Rejbrand

  What is the most elegant (or least ugly) way of using typed constants in a case statement in Delphi? That is, assume for this question that you need to declare a typed constant as in const MY_CONST: cardinal = $12345678; ... Then the Delphi compiler will not accept case MyExpression of MY_CONST: { Do Something }; ... end; but you need to write case MyExpression of $12345678: { Do Something }; ... end; which is error-prone, hard to update, and not elegant. Is there any trick you can employ to make the compiler insert the value of the constant (preferably by checking the value of the constant under const in the source code, but maybe by looking-up the value at runtime)? We assume here that you will not alter the value of the "constant" at runtime.

• Does Ruby on Rails "has_many" array provide data on a "need to know" basis?

  - by Jian Lin

  On Ruby on Rails, say, if the Actor model object is Tom Hanks, and the "has_many" fans is 20,000 Fan objects, then actor.fans gives an Array with 20,000 elements. Probably, the elements are not pre-populated with values? Otherwise, getting each Actor object from the DB can be extremely time consuming. So it is on a "need to know" basis? So does it pull data when I access actor.fans[500], and pull data when I access actor.fans[0]? If it jumps from each record to record, then it won't be able to optimize performance by doing sequential read, which can be faster on the hard disk because those records could be in the nearby sector / platter layer -- for example, if the program touches 2 random elements, then it will be faster just to read those 2 records, but what if it touches all elements in random order, then it may be faster just to read all records in a sequential way, and then process the random elements. But how will RoR know whether I am doing only a few random elements or all elements in random?

• Where to open sessions in a Spring/Hibernate stack?

  - by CaptainAwesomePants

  I'm trying to figure out a good design for a Spring/Hibernate app. When creating such an app, it appears like there are a handful of major decisions. The first major decision seems to be where to put the session/transaction boundary. It seems like I have 3 major choices: as a filter before controllers are even invoked, immediately below the controllers at the service call level, and stuffed way below the business level in repository calls. It seems to me like the right call is the middle path, but I'm not sure. I don't want my transactions open too long, but at the same time, I don't want to constantly worry about detached objects and lazy loading in the business logic. Still, there are some downsides. For instance, it makes it hard for the business logic to make a remote call without holding up a transaction for a few seconds. I wonder if there's a better way?

• A quick over view of facebook's db?

  - by Matt

  Hey guys I find it hard to believe that Facebook uses simple sql, surely it would use some other method but lets assume for now it does use sql how would the code assimilating the 'wall' work? Lets say that there is three tables (just for the example) Friends: id (entry key) - uid(your id) - fid (your mates' id) Wall:id (entry key) - username - comment - time - commentcount comments: id (entry key) - wid (wall id (original comment)) - reply - time Lets forget about the like part and report etc, as well as mod things (ip, ban etc.) How would this work? Select wall.id, wall.username, wall.comment, wall.time, wall.commentcount, comments.wid, comments.reply, comments.time FROM wall inner join comments ON wall.id=comments.wid ORDER BY wall.time; That's your own wall but how do they get friend's? A heap of unions?
