• nth-child doesn't respond to class

  - by Arne Stephensson

  Is it possible to get the nth-child pseudo-selector to work with a specific class? See this example: http://jsfiddle.net/fZGvH/ I want to have the second DIV.red turn red, but it doesn't apply the color as expected. Not only that, but when you specify this, it changes the 5th DIV to red: div.red:nth-child(6) When you specify this, it changes the 8th DIV to red: div.red:nth-child(9) It seems to be one DIV behind. There are only 8 DIV tags in the example so I don't know why nth-child(9) even works. Testing using Firefox 3.6, but in my actual production code the same problem occurs in Chrome. I'm not understanding something about how this is supposed to work, would appreciate clarification. Also, this will change the 6th DIV to red, but what I actually want is for it to change the second DIV.red to red: div.red:nth-of-type(6) And I don't understand why nth-child() and nth-of-type() respond differently, since there are only eight tags of the same type in the document.

• Resources to learn about engineering aspects of data analytics (OLAP, warehousing, ETL, etc.)

  - by JT

  I'm a math/stats guy, interested in learning more about the engineering aspects of "data analytics" (this may be an overly broad term, this is a case of "I don't know what I don't know", so I'm not sure how to be more specific). I'm fine with manipulating and analyzing the data once it's already stored somewhere and I can access it, and I'm fine with writing scripts and SQL queries (and have a general knowledge of things like normalization). What I don't know is the whole engineering process of capturing and storing the data. For example, terms I've heard thrown about that I only vaguely understand the meaning of include: - OLAP, OLTP - Data warehousing - ETL - ??? What's a good book (or any other resource) to learn about these kinds of things? What are things I should know about database design (normalization seems kinda "obvious" to me, something I would have done even before I knew the term -- is there anything else?)? In other words, for jobs falling under the umbrella term of "analytics engineer", what kinds of things should I know?

• facebook iframe application gives null GET/POST

  - by misterjinx

  hey everybody, I came up to something really strange with a facebook iframe application. I don't know why but my global supervariables $_GET and $_POST are empty (nulls actually)! As far as i know, when using iframe for doing applications all the specific facebook variables are kept inside the $_GET variable. But for some reason now I don't have anything. I don't know what might be the problem. And as this wouldn't be enough, when i submit a form using POST as method, my $_POST variable is also null! What you guys think might be the problem? I've spent half a day trying to figure this out, but i didn't get any result.

• Forumotion profile customization using jQuery based on URL

  - by Harvengure

  The idea is have a jQuery snippet (I like Jquery...I can understand it better then regular javascript) that will detect that when it has been run on a profile with a url such as "http://customize.forum-motion.com/profile.forum?mode=viewprofile&u=1" (just as an example)...then upon detecting that it is a url of a profile...fetch data from a specific (and most likely hidden) element before wrapping that data in css tags and appending it to the heady of the current document. In short I'm trying to figure out how to make a sort of profile customization system where users can create their own css. The biggest problem I am having so far is figuring out how to make it so that the snippet can figure out what URL its being run on. Is there a function that can do this in jQuery at all?

• Define Servlet Context in WAR-File

  - by er4z0r

  Hi, How can I tell e.g. Tomcat to use a specific context path when given my WAR-File? Example: I have a war file created by maven build and the resulting name of the file is rather long. So I do not want the tomcat manager application to use the filename of the war as the context. Supplying a context.xml in META-INF did not produce the desired results I also found this in the documentation for the path attribute of Context: The value of this field must not be set except when statically defining a Context in server.xml, as it will be inferred from the filenames used for either the .xml context file or the docBase. So it does not seem to be the right way to tell the application-server what the path for my WAR should be. Any more hints?

  - by Kyriakos Leivadas

  i've got a problem and i hope someone can solve it. I parsed some html to a nsstring and im trying to trim all of the characters and keep some specific words. The problem is that i trimmed all the characters from the nsstring that i didnt want but the weird thing is that i cant get rid of all the whitespace. i used all the techniques i read from other answers but still some whitespace remains. here is my code -(void)requestFinished:(ASIHTTPRequest *)request{ NSString *htmlData = [request responseString]; NSCharacterSet *garbage = [NSCharacterSet characterSetWithCharactersInString:@"qazwsxedcrfvtgbyhnujmik,ol.p;/[]'QAZWSXEDCRFVTGBYHNUJMIKOLP()\"-1234567890#{}=:+_&!`<>"]; //im doing this to remove all characters except non-english chars htmlData = [htmlData compomentsSeparatedByCharactersInSet:garbage ]compomentsJoinedByString:@""]; htmlData = [htmlData stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; htmlData = [htmlData stringByReplacingOccurencesOfString:@"[\n\t\r ]+" withString@""]; htmlData = [htmlData stringByReplacingOccurencesOfString:@" " withString:@""]; NSLog(@"%@",htmlData); } i get this result: nonenglishwordsnonenglishwords nonenglishwordsnonenglishwords (whitespace or new lines in middle remains) thank you.

• Choosing MooTools over Google closure?

  - by Shekhar

  I am in a process to select javascript library for our new web application. This app is not very UI heavy but has forms, reports, search, calendars, tabs and target multiple countries like most web apps. We are a tiny team. Biggest concern is maintainability and readability of the code. We are Python programmers. After evaluating many other javascript frameworks we have narrowed down to mootools and google-closure. We loved mootools syntax. It took us no time to learn. It's like Python. On other hand we were stumped seeing private/public in google closure. It's tempting to go for mootools however, I would love to hear from you about specific advantages these frameworks offer over each other.

• insertNewObjectForEntityForName:inManagedObjectContext: returning NSNumber bug?

  - by beinstein

  I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set one specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 I've tried everything from clean all targets, to restarting both mac and iPhone, even editing the model so that the relationship in question is to-one instead of to-many. No matter what I do, the same problem appears. Has anyone ever seen anything like this before?

• Prototype mouseleave for two connected elements

  - by TenJack

  I have created a small navigation element that is positioned right on top of another element. It is only shown when a user mousenters/mouseovers the main element. I am having some trouble with the prototype. I would like this small nav element to be hidden when a user mouses out of the main box, but I would also like the small nav element to remain visible if a user mouses out of the main box but mouses into the small nav at the same time. This is my attempt so far with some pseudo-code to hopefully explain: $('main_box').observe('mouseenter', function(){ $('small_div').show() }) $('main_box').observe('mouseleave', function(){ if this element is $('small_div') then Event.stop() $('small_div').observe('mouseleave', function(){ if this element is $('main_box') Event.stop observe $('main_box') mouseleave else $('small_div').hide(); }) else $('small_div').hide(); }) The main thing I'm having trouble with is figuring out what element the mouse is over at a given point in time. Is there a way to do something like: on mouseleave do blah unless the mouse is over a specific element then do not do blah?

• Should you remove all warnings in your Verilog or VHDL design? Why or why not?

  - by Brian Carlton

  In (regular) software I have worked at companies where the gcc option -Wall is used to show all warnings. Then they need to be dealt with. With non-trivial FPGA/ASIC design in Verilog or VHDL there are often many many warnings. Should I worry about all of them? Do you have any specific techniques to suggest? My flow is mainly for FPGAs (Altera and Xilinx in particular), but I assume the same rules would apply to ASIC design, possibly more so due to the inability to change the design after it is built.

• How does twitter server get to know single tweet ID from URL fragment segment?

  - by Morgan Cheng

  Each tweet has a single URL such as http://twitter.com/#!/DeliciousHot/status/23189589820702720. The tweet identification (/DeliciousHot/status/23189589820702720) is in the URL fragment segment which is not actually sent to server. Originally, I thought it works this way: The URL response doesn't have this tweet specific info. It is JavaScript module that extracts tweet id from current browser URL and fetch tweet payload with AJAX. The page content is then updated with the tweet payload. To my surprise, it is doesn't work this way! With Firebug, you can view that response of http://twitter.com/#!/DeliciousHot/status/23189589820702720 has tweet payload "10 Signs of a True Gentleman" text in inline JavaScript. The tweet payload is not fetched by another AJAX. So, how does Twitter server get to know the expected tweet ID even it is in URL fragment segment?

• Dealing with distractions

  - by Onorio Catenacci

  How can I cut-out distractions? Are noise-canceling headphones suitable, and are any specific models recommended? I had a fellow programmer that used to use some headphones to help her shut out distractions and focus on her work. Lately I find that I am less able to focus without quiet and therefore I'm thinking of investing in some headphones. I'm sorry – I suppose this is sort of an open-ended question but I don't want to spend $50 on headphones only to find out they won't help me.

• What is the motivation behind "Use Extension Methods Sparingly?"

  - by Robert Harvey

  I find them a very natural way to extend existing classes, especially when you just need to "spot-weld" some functionality onto an existing class. Microsoft says, "In general, we recommend that you implement extension methods sparingly and only when you have to." And yet extension methods form the foundation of Linq; in fact, Linq was the reason extension methods were created. Are there specific design criteria where using extension methods are perferred over inheritance or composition? Under what criteria are they discouraged?

• SVN - Get all commit messages for a file?

  - by davidosomething

  Is there a way to get a nice list of all commit messages sorted by file? Something like this (as you can see, I don't want the messages specific to a certain file, just show messages for the entire commit if the file was part of the commit, repeats ok): -- index.php 2010-01-02 03:04:05 * added new paragraph 2010-01-01 03:04:05 * moved header out of index.php into header.php * header.php initial check-in 2009-12-31 03:04:05 * index.php initial check-in -- header.php 2010-01-03 03:04:05 * added new meta tags 2010-01-01 03:04:05 * moved header out of index.php into header.php * header.php initial check-in Additional information: svn log filename does something similar, but I want it to do this: get a list of files that have changed between yyyy-mm-dd (r2) and yyyy-mm-dd (r4) (i.e. svn log -q -v -r 2:4 changedfiles.txt strip extraneous crap from changedfiles.txt svn log each file in that list, as in: svn log < changedfiles.txt combinedlog.txt (just pseudocode, i know svn log takes arguments not input, but can't be bothered to write it out)

• Changing the URL of an ExpressionEngine forum

  - by Steph

  I've set up a forum on ExpressionEngine and customised the URL as I want a specific path to the forum. To do this I went to Modules Discussion Forum Forum Board Preferences and in the Forum URL put in my desired URL. Let's call it http://www.mywebsite.com/students/forum/ My homepage displays the latest 5 posts from the forum. It all works except for the URLs which don't go to this URL and instead point to http://www.mywebsite.com/forums/viewthread/xxx Is there an extra step I am missing here? Why doesn't the forum URL just update automatically when I save it?

• Powershell 4 compatibility with Windows 2008 r2

  - by Acerbity

  In my environment I have a single server that has access to pretty much my entire network. That server is running Windows 2008 r2, and I have upgraded Powershell to version 4.0. The question I have is this... Can I run cmdlets from that machine on other machines that are version 4 specific? For instance, when I am using Powershell, even though it is version 4, it doesn't give me an intellisense autocomplete for "Get-Volume" like it would on a 2012 r2 machine. I understand that it won't run on that machine because the infrastructure won't allow for it, but what about a 2012 r2 machine remotely? I am looking to run batch scripts from there for various purposes.

• Xaml not WPF

  - by xan

  I am interested in using Xaml with expression blend for creating user interfaces in an application. However, because of the limitations of the target architecture, I cannot use WPF or C#. So, what I am interested in is in any examples / existing projects or advice from anyone who has experiance of this technology on the use of Xaml in it's "Pure" form as a specification language not tied to WPF. Specific questions: 1) Is it possible to use Blend + Xaml without the WPF elements, or without C# backing classes? 2) Are there any other implementations of Xaml parsers etc. which use different architectures, and can they work with blend or similar tools. 3) Are there alternative editor / designer tools which can help in this situation? I am aware of the MyXaml and MycroXaml projects, and have found a lot of resources on the web about Xaml, but 99% of it relates directly to WPF. This is fine for understanding the concepts of Xaml, but doesn't help with the implimentation I need. Many thanks!

• How to write a shell in Python

  - by panzi

  I've written a small console application that can perform certain tasks. The user interface is similar to things like version control systems or yum etc. So basically you can think of it as a domain specific language. Now I'd like to write a (bash like) shell that can execute and auto-complete this language and has a command history (so I do not have to load and save the quite large xml files on each command). In a nutshell I want something like ipython but not for executing python code but my own DSL. Are there any libraries that help me doing this? I see that there is a readline and rlcompleter module in python but its documentation seems to indicate that this is only for use with the python shell itself, or did I miss something there?

• Negative logical shift

  - by user320862

  In Java, why does -32 -1 = 1 ? It's not specific to just -32. It works for all negative numbers as long as they're not too big. I've found that x -1 = 1 x -2 = 3 x -3 = 7 x -4 = 15 given 0 x some large negative number Isn't -1 the same as << 1? But -32 << 1 = -64. I've read up on two's complements, but still don't understand the reasoning.

• Best language to use when exporting an excel file

  - by Aaron

  I want to write a macro program that takes in data from a text file and then arranges it in a specific manner in an excel file. I don't know which language has the best features for dealing with Excel. I prefer java, and I see someone made an api called JExcelApi, but I'm not sure about it's capabilities. I would like to be able to generate a graph automatically in excel based on the data in a certain column. Is this possible in any language? I would guess that Microsoft's VB or C# would have an advanced feature such as this, but I'm not sure. Thanks.

• flex List Size not updating when itemRenderer resizes itself

  - by duder

  I've got a list with a custom itemRenderer that's just a rectangle of specific size. The list <s:List id="thelist" width="100%" dataProvider="{thelistdata}" itemRenderer="ListItem" borderVisible="true" /> Note the list's border is visible to help with debugging The itemRenderer <s:Rect id="box" width="50" height="50"> <s:fill> <s:SolidColor color="blue"/> </s:fill> </s:Rect> When the itemRenderer receives an event, it changes its size to half box.width = 25; box.height = 25; I see the itemRenderers are resizing themselves correctly, but the list itself stays the same size and the border stays where it is. Anyone knows how to fix this bug. Basically the list should refresh its size too to fit the smaller boxes.

• RewriteCond and Full QUERY_STRING

  - by Tim

  I'm having hard time getting my head wrapped around this one - and it should be trivial. I would like to redirect one URL with a specific query string to another URL. I want to send any requests that contain the query string in the URL http://mysite.com/index.php?option=com_user&view=register To: http://mysite.com/index.php?option=com_regme&view=form&regme=4&random=0&Itemid=6 If they add anything to the end of the first URL, it should still go to the second URL so that they cannot bypass the redirection. Nothing in the first query string needs to be preserved and passed to the second - all I want to do is change the URL completely. I'm tearing my hair out trying to get this to work yet it should be trivial. Suggestions? Thanks, -Tim

• How to obtain Bing maps like InfoWindow in Google Maps?

  - by BillB

  I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

• Looking for a generic handler/service for mongodb and asp.net / c#

  - by JohnAgan

  I am new to MongoDB and have a perfect place in mind to use it. However, it's only worth it if I can make the queries from JavaScript and return JSON. I read another post on here of someone asking a similar question, but not specific to C#. What's the easiest way I can implement a generic service/handler in asp.net/c# that would allow me to interact with mongodb via JavaScript? I understand JavaScript can't call mongodb directly, so the next best thing is what I'm looking for.
