• Bootstrap site mobile view not using full viewport

  - by jbarnett

  I'm currently making a responsive blog using the bootstrap 3.0 framework. I'm using the 1197 Max-width container for my content and it renders fine on desktops. However, when I try opening the site on my phone (I'm using an Android Galaxy Note 2), there is a lot of extra padding on the right and left sides of the viewport. I've tried following the API docs and guides as close as possible, but still can't get this to work. Here is the site I am working on http://www.justinbar.net Does anyone know what is going on with this? Am I doing something wrong, or do I need to override default behavior (which sounds a bit hacky to me).

• jQuery link nudge and color transform

  - by DaveKingsnorth

  Hey everyone, I have achieved the effect described in the title using the following code: $(document).ready(function(){ $('.button').mousedown(function() { $(this).animate({ 'top': '3px' }, 70); }); $('.button').mouseup(function() { $(this).animate({ 'top': '0px' }, 70); }); $('.button').hover(function() { $(this).stop().animate({ color: '#fff', backgroundColor: '#000' }, 250); }); $('.button').mouseout(function() { $(this).stop().animate({ color: '#000', backgroundColor: '#fff' }, 250); }); }); I am pretty sure that that this code can be reduced significantly, can anyone help me out? Please note that I want the button to animate when the mouse is clicked and not return to it's original position until the mouse is released. Cheers

• Do you leave historical code commented out in classes that you update?

  - by 18Rabbit

  When you need to obsolete a section of code (say either the business rules changed, or the old system has been reworked to use a new framework or something) do you delete it from the file or do you comment it out and then put in the new functionality? If you comment it out, do you leave a note stating why it was removed and what it was originally intended to do? I ask mainly because I've done a lot of contract work for different places over the years and sometimes it's like excavating a tomb to find the actual code that is still being used. Why comment it out and leave it in the file if source control has a record of what used to be there? If you comment out a method do you also comment out/delete any methods that were exclusively used by that method? What do you think the best practices for this should be?

• Is it possible to get the current request that is being served by node.js?

  - by user420504

  I am using express.js. I have a need to be able to log certain request data whenever someone tries to log a message. For this I would like to create a helper method like so function log_message(level, message){ winston.log(level, req.path + "" + message); } I would then use the method like so. exports.index = function(req, res){ log_message("info", "I'm here"); } Note that I am not passing the req object to the log_message function. I want that to be transparently done so that the log_message API user does not need to be aware of the common data that is being logged. Is there a way to achieve this with express.js/node.js. Is the request object available from a global variable of some sort?

• Lucene boost: I need to make it work better

  - by zvikico

  I'm using Lucene to index components with names and types. Some components are more important, thus, get a bigger boost. However, I cannot get my boost to work properly. I sill get some components appear later (get worse score), even though they have a higher boost. Note that the indexing is done on one field only and I've set the boost to that field alone. I'm using Lucene in Java. I don't think it has anything to do with the field length. I've seen components with the same name (but different type) get the wrong score.

• With Google's #! mess, what effect would a redirect on the converted URL have?

  - by Ne0nx3r0

  So Google takes: http://www.mysite.com/mypage/#!pageState and converts it to: http://www.mysite.com/mypage/?_escaped_fragment_=pageState ...So... Would be it fair game to redirect that with a 301 status to something like: http://www.mysite.com/mypage/pagestate/ and then return an HTML snapshot? My thought is if you have an existing html structure, and you just want to add ajax as a progressive enhancement, this would be a fair way to do it, if Google just skipped over _escaped_fragment_ and indexed the redirected URL. Then your ajax links are configured by javascript, and underneath them are the regular links that go to your regular site structure. So then when a user comes in on a static url (ie http://www.mysite.com/mypage/pagestate/ ), the first link he clicks takes him to the ajax interface if he has javascript, then it's all ajax. On a side note does anyone know if Yahoo/MSN onboard with this 'spec' (loosely used)? I can't seem to find anything that says for sure.

• Error when changing or resetting FBProfilePictureView profileId

  - by Jeff Schwartz

  I have programmatically added an FBProfilePictureView object to a view. When initially logging in, the user's profile picture displays as expected when setting the profileId of the object within the FBLoginViewDelegate method loginViewFetchedUserInfo:user:. However, when logging off the following line of code produces an error: profilePicture.profileId = nil; The error thrown is: [__NSCFNumber isEqualToString:]: unrecognized selector sent to instance Note: This was only an issue after I incrementally upgraded the iOS SDK from 3.5 to 3.8. If anyone has encountered this issue, please let me know. Thanks!

• PHP and Javascript cookies

  - by shummel7845

  Can I access a cookie written with jQuery's cookie plug-in with PHP? I know you can't set Javascript equal to PHP or vice versa, but IN ESSENCE is: $.cookie('var') = $_COOKIE['var']? Again, I know you can't set them equal to each other, but if I set it in jQuery and then go to another page, can PHP access it? I've read lots of posts about this, but I can't seem to find an answer to this part. Note, if I look in Firefox's preferences, I can see the cookies are there, so I know they're set.

• How to store and retrieve file in mongoengine?

  - by Seiverence

  I am attempting to store and retrieve file within mongodb, but am having issues with the retrieval. class Animal(Document): genus = StringField() family = StringField() photo = FileField() def get_file(): marmot = Animal.objects(genus='Marmota').first() photo = marmot.photo.read() content_type = marmot.photo.content_type print marmot.family # Prints out "Sciuridae" print content_type # Gives me an error, as content_type is "None" def save_file(): marmot = Animal( genus='Marmota', family='Sciuridae') marmot_photo = open('marmot.jpg', 'r') marmot.photo = marmot_photo marmot.photo.content_type = 'image/jpeg' marmot.save() When I check mongodb, it appears the document does save after the save_file, but when I call get_file, it appears the content_type is "None"? Am I saving and retrieving the file correctly? If not, whats wrong with the code? NOTE: The issue appears only to occur in the Windows environment. When run on linux, it works fine... very confused.

• Java Programming Help

  - by user215049

  hi, im a bit confused on this and i dont know how to solve this question that i have been asked, id be grateful if you could assist me on this question, maybe try to tell me what needs to be done, and how. the question is: Write a method called countChars which takes an InputStream as a parameter, reads the stream and returns the number of characters it contains as an int. Any IOExceptions which might occur in the method should be passed back to the method's caller. Note that the method header should show that it is possible that an exception might occur. i attempted this question with the following code: public class countChars { public int countChars(int InputStream) { return InputStream; } } and i get an error message saying : Main.java:26: cannot find symbol symbol : method countChars(java.io.InputStream) location: class Main s1 = "" + countChars(f1); ^ 1 error

• C++ vector that *doesn't* initialize its members?

  - by Mehrdad

  I'm making a C++ wrapper for a piece of C code that returns a large array, and so I've tried to return the data in a vector<unsigned char>. Now the problem is, the data is on the order of megabytes, and vector unnecessarily initializes its storage, which essentially turns out to cut down my speed by half. How do I prevent this? Or, if it's not possible -- is there some other STL container that would avoid such needless work? Or must I end up making my own container? (Pre-C++11) Note: I'm passing the vector as my output buffer. I'm not copying the data from elsewhere.

• <hash_set> equality operator doesn't work in VS2010

  Sample code: std::hash_set<int> hs1; // also i try std::unorded_set<int> - same effect std::hash_set<int> hs2; hs1.insert(15); hs1.insert(20); hs2.insert(20); hs2.insert(15); assert(hs1 == hs2); hash_set doesn't stores elements in some order defined by hash function... why? Please note that this code works in VS2008 using stdext::hash_set.

• Number 0 is not saving to database as a prefix in SQL Server of CHAR data type column

  - by gmhk

  I am trying to insert an value as '019393' into a table with a CHAR(10) column. It is inserting only '19393' into the database I am implementing this feature in a stored procedure, doing some manipulation like incrementing that number by 15 and saving it back with '0' as the prefix I am using SQL Server database Note: I tried CASTING that value as VARCHAR before saving to the database, but even that did not get the solution Code SELECT @fromBSB = fromBSB, @toBSB = toBSB, @type = Type FROM [dbo].[tbl_REF_SpecialBSBRanges] WHERE CAST(@inputFromBSB AS INT) BETWEEN fromBSB AND toBSB SET @RETURNVALUE = @fromBSB IF(@fromBSB = @inputFromBSB) BEGIN PRINT 'Starting Number is Equal'; DELETE FROM tbl_REF_SpecialBSBRanges WHERE Type = @type AND fromBSB = @fromBSB AND toBSB = @toBSB INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@type, CAST('0' + @fromBSB + 1 AS CHAR), @toBSB) INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@inputBSBName, @inputFromBSB, @inputToBSB) END

• Saving variables (not sessions)

  - by james.bcn

  This may be a silly question, but how do I save variables that are not specific to a particular session. An simple example of why you might want to do this would be a visitor counter - a number that increases by one each time someone visits a web page (note - I'm not actually doing that, my application is different, but that is the functionality I need). The only ways I can think of doing this are either writing the variables to a file, or putting the variables into a database. Both seem a bit inelegant. Is there a better way to to this kind of thing?

• can't compile min_element in c++

  This is my code: #include <algorithm> #include <vector> #include <string> using namespace std; class A { struct CompareMe { bool operator() (const string*& s1, const string*& s2) const { return true; } }; void f() { CompareMe comp; vector<string*> v; min_element(v.begin(), v.end(), comp); } }; And this is the error: error: no match for call to ‘(A::CompareMe) (std::string*&, std::string*&)’ test.cpp:7: note: candidates are: bool A::CompareMe::operator()(const std::string*&, const std::string*&) const I feel that there is some syntax defect, but can't find out which one. Please, help!

• C / C++ / C#: Howto do "mount -a"

  - by Quandary

  Question: In C/C++/C#. (I need it for C#, but C and C++ is also fine). How can I do a mount -a on Linux. I mean programmatically, without starting a process like system("mount -a"); Edit: Note the "-a". My question is not actually about how to mount A mountpoint. It's about how to mount ALL mountpoints in /etc/fstab. That means parsing the file, extracting the mountpoints, check if already mounted, and only if not already mounted, mount...

• New datatype which can have numbers upto 100 digits.

  - by ckv

  Note: This was an interview question and may not have an actual use case currently The question was to design a class that can store numbers which are very very large say each number can have 100 digits. This new class is a datatype like int. What are the different types of constructors, overloads and other functions that you would write. How can this be further extended to support really large floating point numbers. How this can be given to others so that they can reuse the same component with their own additional functionality. My answer consisted of 2 approaches 1. using array of integers to store every say 10 digits 2. using string itself to store the number and perform operations on individual numbers. What would be the best approach?

• Get all Methods with a given return type

  - by Aren B

  Is this code wrong? It's just not returning anything: public IEnumerable<string> GetMethodsOfReturnType(Type cls, Type ret) { var methods = cls.GetMethods(BindingFlags.NonPublic); var retMethods = methods.Where(m => m.ReturnType.IsSubclassOf(ret)) .Select(m => m.Name); return retMethods; } It's returning an empty enumerator. Note: I'm calling it on a ASP.NET MVC Controller looking for ActionResults GetMethodsOfReturnType(typeof(ProductsController), typeof(ActionResult));

• Microsoft SQL Server xml data

  - by cf_PhillipSenn

  This site has a technique to pass xml data around in Microsoft SQL Server: DECLARE @productIds xml SET @productIds ='<Products><id>3</id><id>6</id><id>15</id></Products>' SELECT ParamValues.ID.value('.','VARCHAR(20)') FROM @productIds.nodes('/Products/id') as ParamValues(ID) But what is the syntax if I add another field? The following does NOT work: DECLARE @productIds xml SET @productIds ='<Products><id>3</id><descr>Three</descr><id>6</id><descr>six</descr><id>15</id><descr>Fifteen</descr></Products>' SELECT ParamValues.ID.value('.','VARCHAR(20)') ,ParamValues.descr.value('.','VARCHAR(20)') FROM @productIds.nodes('/Products/id') as ParamValues(ID) Note: Maybe I've constructed my xml wrong.

• Qt Should I derive from QDataStream?

  - by ShaChris23

  I'm currently using QDataStream to serialize my classes. I have quite a few number of my own classes that I serialize often. Should I derive QDataStream to create my own DataStream class? Or is there a better pattern than this? Note that these custom classes are used by many of our projects, so maybe doing so will make coding easier. Another way to phrase this question is: when a framework provides you with a serialization class, how do you handle serializing your own custom-type classes such that you don't have to remember how to serialize them everytime.
