• c++ g++ llvm-clang compiler profiling

  - by anon

  Note, my question is not: how do I tell my compiler to compile with profiling on. I want to profile my compiles process. For each file, I'd like to know how much time is spent on each line of the program. I'm working on a project, some files have huge compile times, I'm trying to figure out why. Is there anyway to do this with g++ or llvm-clang? Thanks!

• php regex - can't find the error

  - by peirix

  Just one simple, specific question: I've got the string {var1}12345{var2}, and I want to get the variable names used. if (preg_match("/{([a-zA-Z0-9]*)}/g", $url, $matches)) { print_r($matches); } If I remove the global flag, it works, but I only get the first variable, as expected. Why isn't it working with a global flag? It works when I'm testing it with the Regex Tester

• JQuery Tabs: How to get a list of the tab titles

  - by user340254

  As the title suggest, my question is what is the best way to get or build a list of the titles for the set of tabs. I was thinking I would have to build the list in a for loop, but there does not appear to be any 'name' or 'title' property where you could do something like this: var $tabs = $('contentContainer').tabs(); $tabs.tabs( 'title', index );

• What features would you like to see added to your favorite programming language?

  - by George Edison

  Are there any features you would like to see added to a programming language? Maybe... A programming construct An extra operator A built-in function you think would be useful I realize questions like this are frowned upon, but I think this one is a genuine programming question that can be answered and the answers will spawn valuable discussion. (And it's community wiki.) Here is one of mine: How come C++ has no exponent operator, like Python's **?

• c# bound Datagridview

  - by Jin

  I have a datagridview and it is bound to a stored procedure which returns a number of result columns. There is also a binding navigator with "Add New" button included. If I click "Add New" button, it creates a new row in datagridview automatically, and If I leave that new row by clicking a different row. datagridview invokes "commit" or something. so the question is How do I make datagridview not to commit adding a new row when I leave the cell?

• Does anyone know what happens if you do not implement iequtalable when using generic collections?

  - by ChloeRadshaw

  I asked a question here : http://stackoverflow.com/questions/2476793/when-to-use-iequatable-and-why about using Iequatable. From the msdn: The IEquatable(T) interface is used by generic collection objects such as Dictionary(TKey, TValue), List(T), and LinkedList(T) when testing for equality in such methods as Contains, IndexOf, LastIndexOf, and Remove. If you dont implement that interface what exactly happens?? Exception / default object equals / ref equals?

• What is the best way to flag some elements in MATLAB? using NaN or Inf? or something else?

  - by Kamran Bigdely Shamloo

  As you may know, in many occasions, there is a need to flag some elements of a matrix. For example when we have weighted adjacency matrix, and our graph is not fully connected, we have to flag some elements to show that there is no edge between those nodes. The question is how to do that? Is it better to put NaN or Inf on that elements in the matrix? or something elese(such as -1)?

• Cannot have a qualifier in the select list while performing a JOIN w/ USING keyword.

  - by JuiceBerry123

  I am looking at a practice test that doesn't have explanations about the correct answers. The question I'm confused about basically asks why the following SQL statement can never work: SELECT oi.order_id, product_jd, order_date FROM order_items oi JOIN orders o USING(order_id); The answer it gave was: "The statement would not execute because the column part of the USING clause cannot have a qualifier in the SELECT list" Can someone elaborate on this? I am pretty stumped.

• Objects With No Behavior

  - by Patrick Donovan

  I've been teaching myself object oriented programming and I'm thinking about a situation where I have an object "Transaction", that has quite a few properties to it like account, amount, date, currency, type, etc. I never plan to mutate these data points, and calculation logic will live in other classes. My question is, is it poor Python design to instantiate thousands of objects just to hold data? I find the data far easier to work with embedded in a class rather than trying to cram it into some combination of data structures.

• Testing in Scrum

  - by alex

  In Scrum it's a good idea to test frequently when iteration is finished at customer. But the question is what kind of test should I use when some of the prototype is done with customer? In my knowledge Acceptance test is ok when all the iteration is done - but not some part of it. Examples for the test plan would be helpful

• Do autorelease methods always survive a whole method?

  - by Jan Hendrix

  Hi, If I'm correct then the releasing of the pool of autoreleased objects has something to do with the run loop.. I barely have an idea of what that 'run loop' is but my question is, is it possible that the object gets released before the end of the method is reached?

  - by ripper234

  I am using Castle ActiveRecord as my ORM. When I try to store unicode strings, I get question marks instead. Saving unicode strings worked perfectly when I was using mysql, but when I recently switch to SQL Server it broke. How should I go about fixing this?

• Loading external SWF's with Transparent Background

  - by alvincrespo

  Just to get some professional opinions, is it possible to load in an external SWF and set that SWF's background to transparent? This question has nothing to do with embedding the SWF in an HTML page. I already know that setting the WMODE to transparent will create a SWF with a transparent background in a browser.

• Looking for similar projects: Iphone/Android + Google Maps + "external" database = sightseeing map

  - by sniurkst

  Hello, sorry, it's not exactly a programming question, but I am currently in a research state and looking for similar projects, so I could analyze them: It should be application to iPhone or Android or other mobile platform, where, basically, user can access map with "places of interest" and add it's own "place of interest" (with photo and description). Kind of, community generated sightseeing map. I know it is quite simple and not a groundbreaking idea, but my google-fu is quite weak and I can't find anything like that.

• Drupal: assign block to a specific content type

  - by bert

  I made a customized template called node-mynode.tpl.php Whenever a node of type mynode is requested, then node-mynode.tpl.php is automatically used. However, now user wants to see a specific menu block in this case. Question: How can I assign a block to a specific content type? Hint: I have started to look at URL aliases with Pathauto. I suspect one solution may lie in this direction.

• Substitute for Iterator that is Serialization

  - by Mahmoud

  I'm working on a GWT project, and I have a bunch of Java classes that use Java Object Iterators on the server side. As I was reading through the internet...Iterators seem to not be serializable preventing me from sending them over to the client side from the server side. My question is is there an efficient way to serialize the iterator or use a substitute that might be serializable ? Many thanks!

• .NET Framework versions

  - by PintSizedCat

  I've had a little search and I was wondering if there is back compatibility for the .NET framework. The real question is, if there's a program that uses .NET Framework 1.1, can I install 3.5 and be done, or do I have to install 1.1 and then if something uses 3.5 I have to install 3.5 as well?

• How do you efficiently generate a list of K non-repeating integers between 0 and an upper bound N

  - by tucuxi

  The question gives all necessary data: what is an efficient algorithm to generate a sequence of K non-repeating integers within a given interval. The trivial algorithm (generating random numbers and, before adding them to the sequence, looking them up to see if they were already there) is very expensive if K is large and near enough to N. The algorithm provided here seems more complicated than necessary, and requires some implementation. I've just found another algorithm that seems to do the job fine, as long as you know all the relevant parameters, in a single pass.

• Python named print?

  - by Mark

  I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)

• How to programatically search a PDF document in c#

  - by Nathan Reed

  I have a need to search a pdf file to see if a certin string is present. The string in question is definately encoded as text (ie. it is not an image or anything). I have tried just searching the file as though it was plain text, but this does not work. Is it possible to do this? Are there any librarys out there for .net2.0 that will extract/decode all the text out of pdf file for me?
