• web.config inheritance problem

  - by abszero

  Hello everyone, I am having an issue when I try and prevent inhertiance from a parent web.config down to a child specifically related to the node. My parent web.config contains about a dozen appSettings values while my child web.config contains none. Now, I originally began wrapping around only my system.net, web, etc nodes however when I ran my child application I recieved the following error: The configuration section 'appSettings' cannot be read because it is missing a section declaration I really wasn't sure what this meant and a google search didn't yield me any decent results so I attempted to move the location node to also encompass the field in my parent web.config but to no avail. My child web.config is pretty vanilla so I am not sure what the problem is. Any help you can provide would be greatly appreciated! Thanks. The child config is completely vanilla except for the addition of an Xml Namespace and a 'clear' in the config sections as follows: <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <configSections> <clear /> <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/> <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="Everywhere" /> <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> </sectionGroup> </sectionGroup> </sectionGroup> </configSections> The error in question is thrown at The parent web.config is far from vanilla as it is part of an Umbraco install.

• Noob-Ready Cython Tutorials

  - by spearfire

  I know a bunch of scripting languages, (python, ruby, lua, php) but I don't know any compiled languages like C/C++ , I wanted to try and speed up some python code using cython, which is essentially a python - C compiler, aimed at creating C extensions for python. Basically you code in a stricter version of python which compiles into C - native code. here's the problem, I don't know C, yet the cython documentation is aimed at people who obviously already know C (nothing is explained, only presented), and is of no help to me, I need to know if there are any good cython tutorials aimed at python programmers, or if I'm gonna have to learn C before I learn Cython. bear in mind I'm a competent python programmer, i would much rather learn cython from the perspective of the language I'm already good at, rather than learn a whole new language in order to learn cython. 1) PLEASE don't recommend psyco edit: ANY information that will help understand the oficial cython docs is useful information

• Usng Rails ActiveRecord relationships

  - by Brian Goff

  I'm a newbie programmer, been doing shell scripting for years but have recently taken on OOP programming using Ruby and am creating a Rails application. I'm having a hard time getting my head wrapped around how to use my defined model relationships. I've tried searching Google, but all I can come up with are basically cheat sheets for what has_many, belongs_to, etc all mean. This stuff is easy to define & understand, especially since I've done a lot of work directly with SQL. What I don't understand is how to actually used those defined relationships. In my case I have 3 models: Locations Hosts Services Relationships (not actual code, just for shortening it): Services belongs_to :hosts Hosts has_many :services belongs_to :locations Locations has_many :hosts In this case I want to be able to display a column from Locations while working with Services. In SQL this is a simple join, but I want to do it the Rails/Ruby way, and also not use SQL in my code or redefine my joins.

• Eclipse software management

  - by Maroloccio

  How to streamline/automate the configuration of Eclipse? Given N developers running a mixture of Ubuntu and Mac OS X, all with the same version of Eclipse, how to make sure that: Each developer, on top of his favourite "Available Software Sites" selection, has a common set of installation sources? Each developer has an easy (automated?) way of installing a base set of plug-ins? Each developer can just as easily install a custom plugin developed in-house and distributed over the local network? No automatically deployed plugins conflict with any others a developer might already be using? I would post this to serverfault.com if it wasn't that I am more interested in a "scripting" answer than a traditional "system management" solution... ;-)

• Monitor RAM usage on CentOS and restart Apache at a certain usage

  - by Chris

  Hi, I'm running a CentOS 5.3 server with a basic LAMP stack. I've optimized LAMP and my code to run efficiently as possible, but Apache has a memory leak somewhere that kills my server every hour or so. What is the best way to write a script that will monitor the memory usage and if it peaks over, say, 450MB kill all the Apache processes and restart Apache. I know C++/PHP and basic Linux server administration but I'm not familiar with Perl or bash scripting. I'd be open to learn any solutions, though, as a temporary solution while I find the issue.

• Perl graph garbage collection usage

  - by Kevin

  Hi, I have built a tiny application in Perl that displays a graph over time. It graphs garbage collection usage over time. I use gnuplot to display the actual graph. This works fine if the time period is short, like a few hours. However, as the time increases (say a few days), the graph becomes difficult to read as the information gets crammed. Note that there is a tool called gcviewer which performs a similar function, it works by allowing you to choose the percentage of the graph. http://www.tagtraum.com/gcviewer.html Ideally I would like to take this further by adding the ability to "move" within the graph. I am not a developer but am good at scripting, so if there is some module in Perl which would provide this functionality it would be excellent! However, if it cannot be done in Perl, I am not averse to learning a new technology. Inputs are highly appreciated. Thanks!

• How to manage test fixtures for end-to-end testing?

  - by Peter Becker

  Having just set up a test framework for a new web application, I realized I missed one of the big questions: "How do I make tests independent from each other?" Years ago I have set up some complicated Ant scripting to do full cycles of deleting all database tables, creating the schema again, adding test data, starting the application, running one test and then stopping the application. That was a pain to maintain and restricted us to nightly tests due to the time it took to run the full suite. It was still worth it, but I wonder if there is an easier way. Are there alternatives to this approach? The main criterion is that each test should not be affected by any other test in the suite, no matter if it failed or succeeded.

• How do I automate navigation to a website that requires authentication?

  - by Wiz

  Here's what I'm trying to achieve. I would like to write a script that will navigate to a website that requires me to be authenticated as myself, say Facebook, Live Spaces, Twitter or any other, and then have that script search for certain information on one of the pages of the website. I've done something similar in the past with the Windows.Forms WebBrowser control, which is a full blown implementation of IE that can be controlled through code and will store whatever cookies you get once you're authenticated, but it was very unfriendly to modify and I was hoping to use a scripting language instead, maybe Powershell or something of that sort. Are there maybe some good tutorials about this out there on the web? Thanks!

• RichFaces rich:insert takes a long time to output large files

  - by Mark Lewis

  Hello I'm using a RichFaces <rich:insert like this: <rich:panel header="my head"> <a4j:outputPanel ajaxRendered="true"> <rich:insert src="#{MyBacking.myPath}" highlight="groovy" /> </a4j:outputPanel> </rich:panel> If I have a 60k file to output, it takes 23 seconds. I've got a requirement to output the contents of some larger files than that and obviously the larger the file, the larger the wait for content. The recommendation in the answer to another related question is to introduce paging. I will, but the question is, why does it take so long to output 60k of text using JSF/RichFaces? That is, reading off a local disk with Windows XP SP2 PC - I can see from the log the data has already been written to disk from the network. Other scripting languages appear to be faster than this - is it something to do with the JSF lifecycle having to handle the text maybe? Thanks

• Flex - How to call a webservice without crossdomain.xml file

  - by Stephane Grenier

  How can I consume a webservice that hasn't explicitely created a crossdomain.xml? I understand it's for security and to prevent cross-site scripting, but it does seem like a major limitation to the Flex framework. For example, if I want to consume a webservice, which is suppose to be language agnostic, then I can't with Flex. The webservice/server has to be specifically prepared for Flex/Flash. If it's not, then it cannot be consumed. That can't be right can it?

• How to fetch the data from binary log file and insert in our desired table in MySQL?

  - by Parth

  How to fetch the data from binary log file and insert in our desired table in MySQL? I am on my way of scripting a PHP code for Audit Trail, in this I encountered a situation that if there will be new table created then I will not be available with triggers for that new table and hence no tracking could be done for that, so if I code it to create three new triggers for this new table, then how will get the last change done in this table? Hence I found that Binary Log File can be helpfull for me in this case, to fetch the last change for this new table and insert it in tracking table... BUT HOW????

• What language has the longest "Hello world" program?

  - by Kip

  In most scripting languages, a "Hello world!" application is very short: print "Hello world" In C++, it is a little more complicated, requiring at least 46 non-whitespace characters: #include <cstdio> int main() { puts("Hello world"); } Java, at 75 non-whitespace characters, is even more verbose: class A { public static void main(String[] args) { System.out.print("Hello world"); } } Are there any languages that require even more non-whitespace characters than Java? Which language requires the most? Notes: I'm asking about the length of the shortest possible "hello world" application in a given language. A newline after "Hello world" is not required. I'm not counting whitespace, but I know there is some language that uses only whitespace characters. If you use that one you can count the whitespace characters.

• How to integrate pep8.py in Eclipse?

  - by DZPM

  A little background: PEP 8 is the Style Guide for Python Code. It contains the conventions all python programmers should follow. pep8.py is a (very useful) script that checks the code formating of a given python script, according to PEP 8. Eclipse is a great IDE. With the Pydev extension, it that can be used to develop Python I run pep8.py manually when I'm scripting, but with bigger projects I prefer to use Eclipse. It would be really useful to integrate pep8.py in Eclipse/Pydev, so it can be run automatically in all the files in the project, and point to the lines containing the warnings. Maybe there is an obvious way to do it, but I haven't found it yet. Question is: How to integrate pep8.py in Eclipse?

• Helper Casting Functions -- Is it a code smell?

  - by Earlz

  I recently began to start using functions to make casting easier on my fingers for one instance I had something like this ((Dictionary<string,string>)value).Add(foo); and converted it to a tiny little helper function so I can do this ToDictionary(value).Add(foo); Is this a code smell? Also, what about simpler examples? For example in my scripting engine I've considered making things like this ((StringVariable)arg).Value="foo"; be ToStringVar(arg).Value="foo"; I really just dislike how inorder to cast a value and instantly get a property from it you must enclose it in double parentheses. I have a feeling the last one is much worse than the first one though (also I've marked this language agnostic even though my example is C#)

• Why is J2ee/EJBs a dying Trend?

  - by Taranfx

  I might be wrong on this, but I no longer see heavy Business and Web services being hosted using J2ee technologies (Especially EJBs). Having known the power and scalability of J2ee applications, what is keeping developers/decision makers to restrict themselves to Core Java (POJOs) or even other web technologies like PHP, python. Is it the development time? Is it the Ease of configuration? (I feel this should not be a strong reason with Java EE 6, things are simplified) Of course scripting languages are faster to develop, we cannot ignore the fact that they are inherently not-as-scalable as Java Applications are (using App servers)

• When will NAnt reach version 1.0

  - by sundar venugopal

  I like Nant very much. I do a lot of scripting with NAnt. It is a great little tool. Since NAnt is pre 1.0, when problems occur, I often think if that it is a problem with NAnt itself, but this is not always the case. One funny example: After running the oracle scripts I parsed the log output to make sure there was no problem. I was testing this with a small log file and it was fine. I used the task to load the file contents to a string property and used a regex to search for errors. When I used this script for a large log file, I stopped getting the "build failed" message at the bottom, because I was printing the error messages. Because the "build failed" was hiding at the top, I thought NAnt crashed, but it worked fine. It would be better for NAnt to have a 1.0 release. Any reasons why not?

• Tools to test softwares against any attacks for programmers ?

  - by berkay

  in these days, i'm interested in software security. As i'm reading papers i see that there are many attacks and researchers are trying to invent new methods for softwares to get more secure systems. this question can be a general including all types of attacks.There are many experienced programmers in SO, i just want to learn what are using to check your code against these attacks ? Is there any tools you use or you don't care ? For example i heard about,static,dynamic code analysis, fuzz testing. SQL injection attacks Cross Site Scripting Bufferoverflow attacks Logic errors Any kind of Malwares Covert Channels ... ... thanks

• newbie: how to upload images from a form with PHP and mySQL

  - by paracaudex

  I'm creating a web app (locally, so security doesn't matter) in PHP where the user uploads a set of information and a small .jpeg, which is then inserted into a mySQL table. I can do this no problem with all the text data, but I'm not sure how to cause the image to upload alongside it. I assume I will have to use the blob data type and input type="file", but I fooled around with that a little bit and the solution doesn't seem to be an intuitive extension of how input type="text" works. Do I need to do a lot more PHP scripting to get this to work? Is it possible to upload an image with a form, or is there a necessary intermediate step?

• How can I put all twill commands together into one piece of code in a .py file?

  - by brilliant

  Hello everybody! I have just started exploring TWILL. Twill is an amazing scripting language for Web browsing and it does all I want!!! So far I've been using twill from a Python shell (IDLE (Python GUI) to be precise) and I do things in the way of executing commands one by one (I mean, I type one command, run it, then type the next command): But I don't know how to put all these commands together in one .py file, so that they would all be executed one by one automatically. It seems that there is such possibility in twill. This example from the twill documentation page (you can see it HERE) shows us one piece of code consisting of several commands: So, my question is: How can I put all commands together in twill?

• How prevalent is the use of Emacs' eshell in multi-platform development?

  - by pajato0

  I've only recently become aware of Emacs' eshell tool. It looks quite powerful in that it is entirely written in Emacs Lisp and does not require native subshell support. The Emacs info documentation is a bit sparse but EmacsWiki has pretty decent information, at least on a first glance. Given the potential value of eshell as a scripting tool/programmer's aid that works equally well on multiple platforms I'm wondering how prevalent the use of eshell versus the normal (bash) shell is among software developers. Would those of you who have taken the time to learn it recommend it or is it one of those many interesting ideas that did not really pan out?

• Which hosting will let me execute my own EXE with PHP?

  - by guitar-

  I have a task that PHP (or any server-side scripting language) isn't practical for. It involves a lot of file I/O, processing, etc. and it will execute a lot faster using the program I made in C instead of PHP. Do any hosts allow you to upload your own EXE files and run them on the server using PHP's exec, shell_exec, etc. functions? Do you need a dedicated server to do this? Also, I don't know if Facebook's PHP HipHop is out yet, but I really don't want to use that.

• Programmer's editor or IDE for C code

  - by Yktula

  I feel like this question has been repeated here, but I couldn't find it. What open-source programmer's editor or IDE is best for writing code in C? A GUI and integration with Clang for static code analysis or git for version control would be convenient, but aren't necessary. I would ideally use two editors: one feature-filled IDE and one with a small memory footprint, but editors like jEdit, Geany, Diakonos, nano, etc. don't satisfy many of my needs, which include: Good support for refactoring and code completion. Extensibility in C or a "modern" scripting language (i.e. Ruby or Python) Relatively good performance and lack of bloated-ness

• Writing UTF8 text to file

  - by sonofdelphi

  I am using the following function to save text to a file (on IE-8 w/ActiveX). function saveFile(strFullPath, strContent) { var fso = new ActiveXObject( "Scripting.FileSystemObject" ); var flOutput = fso.CreateTextFile( strFullPath, true ); //true for overwrite flOutput.Write( strContent ); flOutput.Close(); } The code works fine if the text is fully Latin-9 but when the text contains even a single UTF-8 encoded character, the write fails. The ActiveX FileSystemObject does not support UTF-8, it seems. I tried UTF-16 encoding the text first but the result was garbled. What is a workaround?

• How to handle value types when embedding IronPython in C#?

  - by kloffy

  There is a well known issue when it comes to using .NET value types in IronPython. This has recently caused me a headache when trying to use Python as an embedded scripting language in C#. The problem can be summed up as follows: Given a C# struct such as: struct Vector { public float x; public float y; } And a C# class such as: class Object { public Vector position; } The following will happen in IronPython: obj = Object() print obj.position.x # prints ‘0’ obj.position.x = 1 print obj.position.x # still prints ‘0’ As the article states, this means that value types are mostly immutable. However, this is a problem as I was planning on using a vector library that is implemented as seen above. Are there any workarounds for working with existing libraries that rely on value types? Modifying the library would be the very last resort, but I'd rather avoid that.
