• Tabular.vim : how to align on the first occurrence of 2 different delimiters placed at the beginning of Words?

  - by ThG

  I have installed the Tabular plugin, which works very well for me, as long as there are no complicated regexes involved… But I have this list : one @abc @rstuvw &foo three @defg &bar four @mn @opq &kludge &hack twelve @hijkl &baz &quux I wish to align it that way (on @… first, then on &…) : one @abc @rstuvw &foo three @defg &bar four @mn @opq &kludge &hack twelve @hijkl &baz &quux which means I have 3 problems at the same time : align on the first occurrence of 2 different delimiters (@ and &) which are not really delimiters but "special characters" at the beginning of Words This is far beyond my understanding of both regexes and Tabular.vim How should I proceed ?

• Repeating characters in VIM insert mode

  - by Cthutu

  Is there a way of repeating a character while in Vim's insert mode? For example, say I would like to insert 80 dashes, in something like emacs I would type: Ctrl+U 8 0 - The only way I know how to do it in VIM is to exit normal mode for the repeat argument, then go back into insert mode to type the dash, then exit to insert the actual dashes, AND then go back into insert mode to carry on typing. The sequence is a really long: <ESC> 8 0 a - <ESC> a It would be nice not to switch in and out of modes. Thanks

• Memory leak in chrome.extension.sendRequest()

  - by jprim

  Chrome Version : 9.0.597.19 (Build 68937) beta & current stable I have simplified my code as far as possible. I ended up with the attached extension: content.js (content script run on every site): setInterval(function() { chrome.extension.sendRequest({ }, function(response) { //Do nothing }); }, 1); background.js (background page script): chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { sendResponse({ }); }); When you install this extension, you can observe it eating up memory extremely fast (I got 90MB in 1 min with 9 tabs opened). You can speed up the process by opening more tabs. Of course, the extension I am actually developing does not send requests every millisecond, but only every 3 seconds. This just slows it down, though. A user who has run it in the background for a long time with many tabs opened has reported 100MB of memory usage, and I can reproduce it to a less extreme extent, too.

• Changing a project's files based on solution in Visual Studio 2008

  - by emddudley

  In one C# solution I have several projects that share a CommonAssemblyInfo.cs file, so that certain assembly attributes are shared across all projects. This works fine so long as I only have one CommonAssemblyInfo.cs file. However I have several solutions (applications) which use these projects, and each solution has its own version of CommonAssemblyInfo.cs. How can I make the projects use a different CommonAssemblyInfo.cs file depending on which solution they are in? In the end I want my assemblies to have attributes specific to the solution they were compiled from. I don't think I can make them files Solution files because they can't all be in the same directory with the same filename. I can't use pre-build events because I don't have a particular project which is always built first. I would prefer not to use a build script because I would like to be able to build and run the solutions through the Visual Studio environment.

• Separate one-off code paths

  - by DeadMG

  I'm implementing an application with different code paths that shall be chosen once at startup and then fixed forevermore for that execution- for example, choosing D3D11 or D3D9 rendering path. Obviously I don't want to duplicate all my other code. Is run-time inheritance (no virtual inheritance) a fair solution? I don't want to waste a bunch of performance making virtual lookups when the type was fixed long ago. Not just that, but it makes me nervous that the functions can't be inlined and whether or not it affects RVO and NRVO and such. Am I just being over-concerned about this?

• C# Random of cordinates is linear

  - by Shawn Mclean

  My code is to generate random cordinates of lat and long within a bound: Random lastLat = new Random(); Random lastLon = new Random(); for (int i = 0; i < 50; i++) { int lat = lastLat.Next(516400146, 630304598); //18.51640014679267 - 18.630304598192915 int lon = lastLon.Next(224464416, 341194152); //-72.34119415283203 - -72.2244644165039 SamplePostData d0 = new SamplePostData(); d0.Location = new Location(Convert.ToDouble("18." + lat), Convert.ToDouble("-72." + lon)); AddPushpin(d0); } My output looks like this: Is there something wrong with how my numbers are generated?

• Shorter GUIDs than hashing a user id?

  - by Alex Mcp

  I'm wondering how Instapaper (bookmarklet that saves text) might generate URLs for their bookmarklet. Mine has a script src of something similar to www.instapaper.com/j/AnJHrfoDTRia The quality of these URLs is that they need to never collide, and not be really guessable (so other people can't save to your account). I know a simple approach might be to MD5 their email address (presumed to have been checked on signup for uniqueness), but then I'd end up with a super long string. This isn't a huge issue, but I'm wondering what techniques there are for shorter GUIDs that won't collide too often (this is obviously the tradeoff, but 12 characters above is pretty short in my opinion)

• Fastest way for inserting very large number of records into a Table in SQL

  - by Irchi

  The problem is, we have a huge number of records (more than a million) to be inserted into a single table from a Java application. The records are created by the Java code, it's not a move from another table, so INSERT/SELECT won't help. Currently, my bottleneck is the INSERT statements. I'm using PreparedStatement to speed-up the process, but I can't get more than 50 recods per second on a normal server. The table is not complicated at all, and there are no indexes defined on it. The process takes too long, and the time it takes will make problems. What can I do to get the maximum speed (INSERT per second) possible? Database: MS SQL 2008. Application: Java-based, using Microsoft JDBC driver.

• Looking at the C++ new[] cookie. How portable is this code?

  - by carleeto

  I came up with this as a quick solution to a debugging problem - I have the pointer variable and its type, I know it points to an array of objects allocated on the heap, but I don't know how many. So I wrote this function to look at the cookie that stores the number of bytes when memory is allocated on the heap. template< typename T > int num_allocated_items( T *p ) { return *((int*)p-4)/sizeof(T); } //test #include <iostream> int main( int argc, char *argv[] ) { using std::cout; using std::endl; typedef long double testtype; testtype *p = new testtype[ 45 ]; //prints 45 std::cout<<"num allocated = "<<num_allocated_items<testtype>(p)<<std::endl; delete[] p; return 0; } I'd like to know just how portable this code is.

• Programmatically find maximum static array size in C++

  - by GuyGreer

  I am curious whether it is possible to determine the maximum size that an array can have in C++. #include <iostream> using namespace std; #define MAX 2000000 int main() { long array[MAX]; cout << "Message" << endl; return 0; } This compiles just fine, but then segfaults as soon as I run it (even though array isn't actually referenced). I know it's the array size too because if I change it to 1000000 it runs just fine. So, is there some define somewhere or some way of having #define MAX MAX_ALLOWED_ARRAY_SIZE_FOR_MY_MACHINE_DEFINED_SOMEWHERE_FOR_ME? I don't actually need this for anything, this question is for curiosity's sake.

• How to add libraries in C++?

  - by m00st

  Yea this is a dumb question... However in both of my C++ classes we did not do this at all (except for native libraries: iostream, iomanip, etc.)... My question is can anyone provide a link that gives the general explanation of adding libraries to C++? I do realize what what #include means; it's just I have no clue on the linker/directories in a C++ IDE. So long question short; could I get a general explanation of terms used to link libraries in C++? I'm using c::b w/ MinGW.

• what are most important things that i must know in order to jump into silverlight development

  - by Poni

  I have vast programming knowledge; C++/C#/ActionScript/ASM/PHP..... so learning the language of SilverLight itself isn't of an issue. To keep long story short, when asking this question I'm asking it as a developer who's coming from Flash world - great graphics/sounds/media support, fully cross-platform, ability to combine several SWFs within a "movie" (which also implies code reusability). A Flash developer have pretty much freedom. What are most important things that i must know in order to jump into silverlight development? Did you already make the move to SilverLight from Flash yourself? Are you a "guru" at both? Great, let's hear what you have to say - developer to developer! =)

• Oracle spatial search within distance

  - by KA_lin

  I have the following table Cities: ID(int),City(char),latitude(float),longitude(float). Now based on a user`s longitude(ex:44.8) and latitude(ex:46.3) I want to search for all the cities near him within 100 miles/KM. I have found some examples but don`t know how to adapt them to my case select * from GEO.Cities a where SDO_WITHIN_DISTANCE([I don`t know], MDSYS.SDO_GEOMETRY(2001, 8307, MDSYS.SDO_POINT_TYPE(44.8,46.3, NULL) ,NULL, NULL), 'distance = 1000') = 'TRUE'; Any help would be appreciated. P.S: If it is possible to have the distance and to be sorted P.P.S: I want to do it in this way due to performance issues, I have done this in this way http://www.scribd.com/doc/2569355/Geo-Distance-Search-with-MySQL but it takes too long...

• C++ Generic List Assignment

  - by S73417H

  I've clearly been stuck in Java land for too long... Is it possible to do the C++ equivalent of the following Java code: // Method List<Bar> getBars() { return new LinkedList<Bar>(); } // Assignment statement. List<Foo> stuff = getBars(); Where Foo is a sub-class of Bar. So in C++.... std::list<Bar> & getBars() { std::list<Bar> bars; return bars; } std::list<Foo> stuff = getBars(); Hope that makes sense....

• Unit testing task queues in AppEngine

  - by Swizec Teller

  For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

• ColdFusion Timeout Error

  - by Jason

  I have a scheduled task that runs once a day that builds an XML file that I pass off to another group. Recently the amount of data has greatly increased and is now causing the task to time out (I think). I have tried to optimize my script as much as possible but with no luck. It times out long before an hour and I don't get any kind of ColdFusion error. Instead I get a "This page cannot be found" after it runs. Could this be a timeout someplace other than Coldfusion? Is there a more efficient way to build this XML file? select PersonID, FirstName, LastName from People select d.DepartmentID, DepartmentName, pd.PersonID from Department d inner join PersonDepartment pd on d.DepartmentID = pd.DepartmentID select PaperID, PaperTitle, PaperDescription, pp.PersonID from Paper p inner join PersonPaper pp on p.PaperID = pp.PaperID select DepartmentID, DepartmentName from getDepartments where PersonID = #getPeople.PersonID# select PaperID, PaperDescription from getpapers where PersonID = #getPeople.PersonID# #getPeople.PersonID# #getPeople.Firstname# #getPeople.LastName# #getPersonDepartments.DepartmentID# #getPersonDepartments.DepartmentName# #getPersonPapers.PaperID# #getPersonPapers.PaperDescription# Done!

• What's wrong with the architecture of a game object drawing and updating itself?

  - by Ricket

  What are the reasons for and against a game object drawing and updating itself? For example, if you have a game where the player has a position on screen, why not have an all-encompassing class: public class Player { private int x, y, xVelocity, yVelocity; private Sprite s; //... public Player() { // load the sprite here, somehow? } public void draw(CustomGraphicsClass g) { g.draw(s, x, y); } public void update(long timeElapsed) { x += (xVelocity * timeElapsed); y += (yVelocity * timeElapsed); } } What is wrong with this design? What are the downfalls or concerns? How would you better write something like this, or better architect this type of thing in a game? Also, somewhat connected, how would you implement loading that Sprite image? And furthermore, how would you then implement collision between two Players? (I should probably separate these extra two questions into new questions, huh?)

• C++ private pointer "leaking"?

  - by jbu

  I'm going to create a class to hold a long list of parameters that will be passed to a function. Let's use this shorter example: class ParamList{ public: ParamList(string& a_string); string& getString(); //returns my_string private: string& my_string; } My question is this: my_string is private, yet I'm returning the reference to it. Isn't that called something like private pointer leaking in C++? Is this not good programming practice? I want callers of getString to be able to get the reference and also modify it. Please let me know. Thanks, jbu edit1: callers will use getString() and modify the string that was returned.

• How to get "printer ready bytes" from a source in c#?

  - by luis_villase

  Hey everyone! I'm in a bit of trouble here, hoping you can help a fellow programmer out. I have an application that receives a pointer to raw bytes (plus length and stuff) and sends said raw data to a printer. This is important, I have no choice but to use this method to get any printing done. If I send a raw string, it will print with no problem. However, I need to be able to print formatted text, images, etc. So the thing is... I would like to be able to get printer ready bytes from a given source (maybe a pdf, or html, does not matter as long as it contains formatted text and/or images). It would be like "splitting" the print command like so: a) Open file and read data b) Load printer data into memory c) Send bytes to printer Obviously, I've got a) and c) covered, it's b) the one that's breaking my head. Any thoughts? Thanks in advance for your help.

• SQL tables using VARCHAR with UTF8 (with respect to multi byte character length)

  - by Elius

  Like in Oracle VARCHAR( 60 CHAR ) I would like to specify a varchar field with variable length depending on the inserted characters. for example: create table X (text varchar(3)) insert into X (text) VALUES ('äöü') Should be possible (with UTF8 as the default charset of the database). On DB2 I got this Error: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001 (Character data, right truncation occurred; for example, an update or insert value is a string that is too long for the column, or a datetime value cannot be assigned to a host variable, because it is too small.) I'm looking for solutions for DB2, MsSql, MySql, Hypersonic.

• Generic object load function for scala

  - by Isaac Oates

  I'm starting on a Scala application which uses Hibernate (JPA) on the back end. In order to load an object, I use this line of code: val addr = s.load(classOf[Address], addr_id).asInstanceOf[Address]; Needless to say, that's a little painful. I wrote a helper class which looks like this: import org.hibernate.Session class DataLoader(s: Session) { def loadAddress(id: Long): Address = { return s.load(classOf[Address], id).asInstanceOf[Address]; } ... } So, now I can do this: val dl = new DataLoader(s) val addr = dl loadAddress(addr_id) Here's the question: How do I write a generic parametrized method which can load any object using this same pattern? i.e val addr = dl load[Address](addr_id) (or something along those lines.) I'm new to Scala so please forgive anything here that's especially hideous.

• Looking for a specific kind of WEB framework, no malarkey please

  - by Hello you all men

  We do maintenence on a number of systems. I'm finally in a place where I'm teh fucking boss for once, and have to design a large system that will have a long maintenance contract. There's a couple of tasks I find myself always repeating: 1) similar tasks for users with JS and those without 2) similar things for contents and rss/atom feeds, etc. To combat these I will need appropriate handling of assets (think JS files, CSS, themes/templates, etc.), excellent auth/user systems, javascript/ajax forethought, appropriate model setups. Codeigniter fails on many of these. Basically, with enough time I could build this system with Zend, but I'm curious what else is out there as Zend is also kind of a heavy-weight. We need something that is Rapid but maintainable, CodeIgniter is not maintainable. We will have a lot of AJAX APIs in place for the design team to play with. At first I thought jQuery was cool, but now I'm looking at Dojo.
