• Limit number of views per day in Django

  - by ariddell

  Is there an easy way to limit the number of times a view can be accessed by a given IP address per day/week? A simplified version of the technique used by some booksellers to limit the number of pages of a book you can preview? There's only one view that this limit need apply to--i.e. it's not a general limit--and it would be nice if I could just have a variable overlimit in the template context. The solution need not be terribly robust, but limiting by IP address seemed like a better idea than using a cookie. I've looked into the session middleware but it doesn't make any references to tracking IP addresses as far as I can tell. Has anyone encountered this problem?

• Finding the right version of the right JAR in a maven repository

  - by Matt McHenry

  I'm converting a build that has 71 .jar files in its global lib/ directory to use Maven. Of course, these have been pulled from the web by lots of developers over the past ten years of this project's history, and weren't always added to VCS with all the necessary version info, etc. Is there an easy, automated way to go from that set of .jar files to the corresponding <dependency/> elements for use in my pom.xml files? I'm hoping for a web page where I can submit the checksum of a jar file and get back an XML snippet. The google hits for 'maven repository search' are basically just finding name-based searches. And http://repo1.maven.org/ has no search whatsoever, as far as I can see. Update: GrepCode looks like it can find projects given an MD5 checksum. But it doesn't provide the particular details (groupId, artifactId) that Maven needs.

• Can I animate a radial gradient in iPhone?

  - by user364782

  I would like to animate a radial gradient to shrink and grow the inner radius, as if it were pulsing. Right now I'm rendering the gradient with CGGradient, but I'm not sure how to animate it. I've seen this topic http://stackoverflow.com/questions/1819311/can-you-animate-gradients-using-quartz-in-an-iphone Which explains how animate a linear gradient with CAGradientLayer, but it doesn't seem like this will draw a radial gradient. Is there an easy way to animate a CGGradient, or some way to create a radial gradient CAGradientLayer? Any thoughts are appreciated.

• My page was attacked via xss, but on ftp all files are not changed?

  - by Dobiatowski

  Hi, yesterday i noticed that sometimes on my webpage shows up javascript errors. when i went to source code, i found that one of .js files was totaly replaced with a ton of porn links. i checked the ftp for this file, but there was just old javascript file without any changes. yet i go back to check source code via browser and indeed there was again original .js today i visited my webpage again and the problem repeated. first visit showed me ton of porn pages cached .js file was hacked but after clearing browser cache js go back to oryginal i checked all files on my ftp against my offilne version, but all files are without any change. in last few years i was attacked by xss few times but in every case it was easy to diagnose and fix. but now i spend 12h and didnt find infection. do you have any idea how to find it? the webpage is: http://robert.frk.pl

• Checking if parsed date is within a date range

  - by Brett Powell

  So I am using a scripting language with c++-like syntax, and I am trying to think of the best way to check if a date is within range. The problem I am running into is that if the current day is in a new month, the check is failing. Here is what my code looks like: if(iMonth >= iStartMonth && iMonth <= iEndMonth) { if(iDay >= iStartDay && iDay <= iEndDay) { if(iYear >= iStartYear && iYear <= iEndYear) { bEnabled = true; return; When I have something like this: Start date: 3 27 2010 End Date: 4 15 2010 Current Date: 3 31 2010 The day check fails because if (iDay <= iEndDay) does not pass. The scripting language doesn't have a lot of time related functions, and I can't compare timestamps because I'm allowing users to put like "03:27:2010" and "04:15:2010" as start/end dates in a config file. I'm assuming I am just not thinking straight and missing an easy fix.

• Database table design vs. ease of use.

  - by Gastoni

  I have a table with 3 fields: color, fruit, date. I can pick 1 fruit and 1 color, but I can do this only once each day. examples: red, apple, monday red, mango, monday blue, apple, monday blue, mango, monday red, apple, tuesday The two ways in which I could build the table are: 1.- To have color, fruit and date be a composite primary key (PK). This makes it easy to insert data into the table because all the validation needed is done by the database. PK color PK fruit PK date 2.- Have and id column set as PK and then all the other fields. Many say thats the way it should be, because composite PKs are evil. For example, CakePHP does no support them. PK id color fruit date Both have advantages. Which would be the 'better' approach?

• Removing the Default Wrap Character From all records

  - by aceinthehole

  I am using BizTalk 2009 and I have a flat file that is similar to the following "0162892172","TIM ","LastName ","760 "," ","COMANCHE ","LN " "0143248282","GEORGE ","LastName ","625 "," ","ENID ","AVE " When I parse it and start mapping it I need to get rid of the quotation marks. I have marked the Wrap Character attribute for the schema as a quotation mark but it doesn't remove it when BizTalk is parsing the file. Is there an easy way to specify the removal of a wrap character or am I going to have to run it through a script functiod every time? Also I would like to be able to remove the trailing spaces as well, if at all possible.

• Can I use PayPal to charge a Credit Card automatically?

  - by Mark

  If I have a Visa card number saved in my database, is there a way I can charge that Visa automatically through the PayPal API without the user having to enter anything? We want to keep this site as easy and hassle-free to use as possible. It would be a variable amount, based on how they use the site. (Don't worry, proper disclaimers will be in place, and the user will be notified) What about these "recurring payments"? That way I don't have to store the CC info on my website, but do they allow variable amounts that I could periodically send to PayPal?

• Reinstalling Debian Package -manager?

  - by hhh

  I have had this problem for too long time: package-manager not working or very unstable, examples here. Now suppose my laptop has very little precious stuff. Is there some easy way to reinstall Debian -package-manager? I don't really have time to fix this problem so I am considering reinstallation of the OS, I have no idea what is causing this repetitive errors with the installers such as aptitude, pip and apt-get. How can I reinstall the package-managers? Perhaps related rebuilding packages and the package manager on debian

• How to prepare a codebase for compiling on both Windows and Unix-based systems

  - by Max

  Hi! I am wondering about different solutions to easily compile my cross-platform application for both windows and unix. Right now I am using a makefile on Ubuntu, but before my codebase grows larger I'd like to perform the steps necessary to compile it on Windows, and then continue doing so regularly to see that it still works. I'd preferably not contaminate my SVN codebase repository with multiple "makefile" solutions, such as VC++ solutions and so on, I'd like a more automatic way. I tried using mingw with make for windows, but it seems my secondexpansion awesomeness doesn't work on the Windows version (or something like that). It wouldn't compile, and also complained about _winNT or something like that not being defined. How should I prepare my codebase for cross-platform easy compiling? Things like buildtools, perhaps autogenerate VS file from makefile, or something similar. Some preprocessor magic in a stdinc file perhaps? Thanks!

• How to make Subversion use Linux system accounts for authentication?

  - by Alejandro García Iglesias

  Hi all, I've set up a Ubuntu Server for Subversion with Apache/WebDAV interface to share repositories with other developers. My question is, how can I make Subversion use the linux system accounts for authentication? This would lead to very easy Subversion account management. Subversion with Apache/WebDAV is currently working with this configuration: Contents of /etc/apache2/mods-available/dav_svn.conf: <Location /svn> DAV svn SVNParentPath /home/svn SVNListParentPath On AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd Require valid-user </Location> I have tried changing AuthUserFile /etc/apache2/dav_svn.passwd with AuthUserFile /etc/shadow with no success. This makes the server to respond with a error 500 internal server error. It's logical, why the Web service should have access to system authentication file? Thanks a lot in advance!

• Whats the deal with python?

  - by gmatt

  My interests in programming lie mainly in algorithms, and lately I have seen many reputable researchers write a lot of their code in python. How easy and convenient is python for scientific computing? Does it have a library of algorithms that compares to matlab's? Is Python a scripting language or does it compile? Is it a great language for prototyping an algorithm? How long would it take me to learn enough of it to be productive provided I know C well and OO programming somewhat? Is it OO based? Sorry for the condensed format of questions, but I'm very curious and was hoping a more experienced programmer could help me out.

• just-in-time list

  - by intuited

  I'd like to know if there is a class available, either in the standard library or in pypi, that fits this description. The constructor would take an iterator. It would implement the container protocol (ie _getitem_, _len_, etc), so that slices, length, etc., would work. In doing so, it would iterate and retain just enough values from its constructor argument to provide whatever information was requested. So if jitlist[6] was requested, it would call self.source.next() 7 times, save those elements in its list, and return the last one. This would allow downstream code to use it as a list, but avoid unnecessarily instantiating a list for cases where list functionality was not needed, and avoid allocating memory for the entire list if only a few members ended up being requested. It seems like a pretty easy one to write, but it also seems useful enough that it's likely that someone would have already made it available in a module.

• Insert multiple rows into temp table with one command in SQL2005

  - by Adam Haile

  I've got some data in the following format: -1,-1,-1,-1,701,-1,-1,-1,-1,-1,304,390,403,435,438,439,442,455 I need to insert it into a temp table like this: CREATE TABLE #TEMP ( Node int ) So that I can use it in a comparison with data in another table. The data above represents separate rows of the "Node" column. Is there an easy way to insert this data, all in one command? Also, the data will actually being coming in as seen, as a string... so I need to be able to just concat it into the SQL query string. I can obviously modify it first if needed.

• Working effectively unit tests / Anyone tried the in-assembly approach?

  - by CodingCrapper

  I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

• How should open source libraries be used on Windows?

  - by Jason Owen

  There are many open-source libraries that can be compiled with Visual Studio. I'm porting a program from Linux to Windows, but it depends on a number of libraries. I don't know what the best practices regarding libraries are on Windows. On Linux, these libraries are typically part of the distribution. To use sqlite on Debian, for example, you need only to install libsqlite3-dev and the include files and libraries (both static and dynamic) are automatically installed and available to your program. If you need a different version than your distribution supplies, you can compile it in your home directory, install it to ~/include and ~/lib, and set the appropriate environment variables so that your compiler includes those directories in its search path. What is the best way to use libraries that are distributed as source on Windows? If I link dynamically rather than statically, is there an easy way to copy required DLLs into the output directory to ease redistribution (assuming license requirements are met)?

• Change default Console I/O functions handle.

  - by b-gen-jack-o-neill

  Hello. Is it possible to somehow change standart I/O functions handle on Windows? Language preffered is C++. If I understand it right, by selecting console project, compiler just pre-allocate console for you, and operates all standart I/O functions to work with its handle. So, what I want to do is to let one Console app actually write into another app Console buffer. I though that I could get first´s Console handle, than pass it to second app by a file (I don´t know much about interprocess comunication, and this seems easy) and than somehow use for example prinf with the first app handle. Can this be done? I know how to get console handle, but I have no idea how to redirect printf to that handle. Its just study-purpose project to more understand of OS work behind this. I am interested in how printf knows what Console it is assiciated with.

• Is it possible to reference object within the same object?

  - by fudgey

  I've been messing around with jQuery plugin code and I'm trying to put all of my common variables into a single object for easy access. I have included a few examples below on how I've done this, but I'm wondering how others deal with this problem. Lets say I have this var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : $('ul#list').children().length } $.extend(options, defaults); // do other stuff } What I'm trying to do is use the ulist object in as a base, then find the number of li's I guess I could do this: var x = function(options){ var defaults = { ulist : $('ul#list'), listLen : 0 } defaults.listLen = defaults.ulist.children().length; $.extend(options, defaults); // do other stuff } or this: var x = function(options){ var defaults = { ulist : $('ul#list') }; var defaults2 = { listLen : defaults.ulist.children().length } $.extend(defaults, defaults2); $.extend(options, defaults); // do other stuff } The above code samples are just thrown together, and only meant to get the idea across to you. Anyway, is there a better way to do this?

• google analytics - event tracking without affecting bounce rate

  - by cmancre

  Hi, I'm studding a way of using Google Analytics to track Ad impressions/clicks. Looks like event tracking is the way to go. Tracking clicks it's easy to implement. My doubt resides on impressions: using event tracking on page load will cut down my bounce rate to 0 using a second profile doesn't look elegant (leave it for last resource) GOAL: John loads page A and leave. Count 1 for impressions and 1 for bounce rate as it should. Is there a way of doing it with Google Analytics?

• Sending variables in URLs in PHP with echo

  - by alexpelan

  Hi all, I can't really find good guidelines through google searches of the proper way to escape variables in URLs. Basically I am printing out a bunch of results from a mysql query in a table and I want one of the entries in each row to be a link to that result's page. I think this is easy, that I'm just missing a apostrophe or backslash somewhere, but I can't figure it out. Here's the line that's causing the error: echo "<a href = \"movies.php/?movie_id='$row['movie_id']'\"> Who Owns It? </a> "; and this is the error I'm getting: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING If you could elaborate in your answers about general guidelines for working with echo and variables in urls, that would be great. Thanks.

• Filling in a multi-choice field in a Sharepoint Doc-Lib using SetDocsMetaInfo Frontpage Server Extentions RPC method

  - by notnot

  I've been given a big chunk of code which eventually calls upon the SetDocsMetaInfo method from Frontpage Server Extension RPC. This is easy enough for most document uploading and property updating, except when dealing with multichoice fields. I've been scouring through MSDN and I can't find anything on how to fill in multiple values for such a field. The general syntax for properties is something like this: [SR|default], with the type (string in this case) followed by a pipe and then the value to be written. Does anyone know the syntax for multichoice fields? references: MSDN: SetDocsMetaInfo

• ASP.Net Treeview - Client side event handling (jQuery??)

  - by The Great Gonzo

  I have a Treeview (bog standard ASP.Net Treeview) that is bound to an Xml source which allows the user to navigate to various parts of our system. Nothing special.... However, I wanted to generate a breadcrumb for use in the main content area on the client side when the user clicks a node in the Treeview control. I know there are mechanisms available for breadcrumb generation (such as site maps) but for various reasons I need to do it when a node is clicked. So far hooking up a click event using the document ready function available as part of jQuery is easy. However, having spent sometime looking I can not see how I navigate back up the tree nodes to get to each parent nodes text value to build the breadcrumb. I have been playing with .parent(), .parents() and .closest() available via jQuery but don't seem to be getting anywhere. Has anyone done anything like this or can anyone provide a better method? Thanks in advance....
