  - by 8888q8888

If operator= is just something default, like copy everything in A to B, how this following code works? vector<double> v(100,1); v = vector<double>(200,2); // if operator= is just a trivail version, how to make sure the old v get cleared?

• Previous version of ant manual

  - by Brian

  Ugh, I can't believe I have to ask this, but where can I find previous versions of the ant manual (http://ant.apache.org/manual/index.html)? That page says, "Please use the documentation appropriate to your current version" but I can't find anything other than the current version (1.8.0) on the Web site - I had to resort to using archive.org to find the old version (which I would consider a hack, not a clean solution)...

• When I change templates in Netbeans, why doesn't anything happen?

  - by Matthew

  I want to modify the "Java class" template, so that the class javadoc comment includes more than just the author. In Netbeans 6.8., I go to Tools Templates Java Java Class, and modify the template. However, nothing seems to change. I tried restarting Netbeans, just in case, but the old template is still used. How do I get Netbeans to recognize changes to the template for Java Classes?

• installing opencv for python issues

  - by vlad

  I'm running OS X Leopard. I followed this site to install it. Trying to run any demo script, I now get "No module named opencv.cv", which is obviously stopping me from doing any programming. I am running python 2.5.1 (yes, I know it's kind of old). Why would this be, and how can I solve it? Thanks

• Put indexes on a table with lots of BOOL/TINYINT?

  - by John Tyler

  An old mentor once told me to place indexes on most things you use a WHERE clause for. Should I put an index on BOOL/TINYINT's? There is a significant amount of them in the table I am working with, and often results are filtered by anywhere from 1-20 of these boolean conditions.

• Is Spring.Threading.Helpers still supported?

  - by Paul Morrison

  I am converting some old C# code, and it has a CountDownLatch using a package called Spring.Threading.Helpers. The odd thing is that I can't find this package on Google - so a) is it still supported? And, if so, where is it documented? b) What I really want to do is wait for a count to get to zero, but interrupt every so many msecs. Would it just be simpler to set up another thread, and do WaitOnes on an Event specifying an interval? TIA

• How do I get the name of the parent folder in a command prompt?

  - by Bernhard Hofmann

  I'm in a Windows Command Line and want the parent folder in a variable. Assuming current directory is "C:\foo\bar", how can I get the value "bar"?

• create a new model instance version instead of update

  - by pablo

  Hi, I have a model with a version field - autocreate timestamp. When a model instance is being saved I want to create a new instance with a new timestamp instead of updating the old model instance. Is it possible? I thought of overriding the model save() method but I don't know how to create a new instance without creating a infinite save() loop. Thanks

• Real world examples of tree structures

  - by Arec Barrwin

  I'm looking for some examples of tree structures that are used in commercial/free software projects, modern or old. I can see examples on wikipedia, but I am looking for more concrete examples and how they're used. For example primary keys in databases are (from what I've read) stored in BST structure or a variation of the BST (feel free to correct me on this) My question isn't limited Binary Search Trees (BSTs), it can include any variation such as red-black, AVL and so on.

• How can I remove connections in Visual Studio "Copy Web Site" tool?

  - by John Hoge

  Visual Studio 2008 has a Copy Web Site tool that remembers previous FTP locations that files have been copied to. There is a "Connections" drop down where they are listed. I'd like to remove some old listings from that, but I can't find where they're stored. I've looked at the solution file, and there's nothing there. John

• Is there a replacement for Paste.Template?

  - by Jorge Vargas

  I have grown tired of all the little issues with paste template, it's horrible to maintain the templates, it has no way of updating an old project and it's very hard to test. I'm wondering if someone knows of an alternative for quickstart generators as they have proven to be useful.

• No getdate() function in Enterprise PostgreSQL

  - by Suezy

  Hi guys, do you have any idea on how to have getdate() function in enterprise postgresql? I upgraded to EDB-PSQL, and now when I tried to restore old data from the free PSQL, it returns error on some tables since there is no getdate(). I believe this should automatically be created upon creating new database? But it didn't. :( Only now() function. Can I create the function instead? Help!

• <asp:Table> Vs html <table>

  - by keith

  What are the pros and cons between using the ASP.Net control compared to the old reliable table html implementation. I know that the asp:Table will end up on the returned page as a html table, and from looking into it so far people are saying its easier to work with the asp:Table in the server side code, but I'd love to hear what the stackoverflow community has to say about the matter.

• What was the most refreshingly honest non-technical comment you saw in the code?

  - by DVK

  OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored proc, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

• How do I tell GWT to not compile a permutation for gears

  - by Clinton Bosch

  I have included gwt-html5-geolocation into my GWT project and was disappointed to find that it doubled up on my number of permutations compiled. Apparently if the browser does not support geolocation API then it falls back to use gears to find out your location. Is there a way to NOT compile a permutation for gears similar to the way you can tell GWT to only compile certain browser permutations? (the geolocation stuff is very much a nice-to-have and frankly if the client is running an old browser then I am happy not to get their location) Thanks
