  - by Daniel

  Hi I'm trying to initialize a session but i get this error: Warning: session_start() [function.session-start]: open(/tmp/sess_7af3ee9ec1350680bedcf63833d160bd, O_RDWR) failed: Permission denied (13) The session.path is set to /tmp with 777 perms.

• Is there any way to delete an HttpOnly cookie from C# Selenium tests?

  - by BenA

  I have a set of C# Selenium tests that need to delete a cookie that has the HttpOnly flag set. Unfortunately the DefaultSelenium.GetCookie() and DefaultSelenium.DeleteCookie() commands aren't able to access the cookie, because it has that HttpOnly flag set. I've confirmed this by removing the flag by hand, and checking that subsequent calls to either of those methods are then happily able to manipulate the cookie in question. Is there any other way to do this via the Selenium .NET client driver? All ideas welcome!

• Sparse quadratic program solver

  - by Jacob

  This great SO answer points to a good sparse solver, but I've got constraints on x (for Ax = b) such that each element in x is >=0 an <=N. The first thing which comes to mind is an QP solver for large sparse matrices. Also, A is huge (around 2e6x2e6) but very sparse with <=4 elements per row. Any ideas/recommendations?

• How to display a date as iso 8601 format with PHP

  - by Matthew James Taylor

  I'm trying to display a datetime from my MySQL database as an iso 8601 formated string with PHP but it's coming out wrong. 17 Oct 2008 is coming out as: 1969-12-31T18:33:28-06:00 which is clearly not correct (the year should be 2008 not 1969) This is the code I'm using: <?= date("c", $post[3]) ?> $post[3] is the datetime (CURRENT_TIMESTAMP) from my MySQL database. Any ideas what's going wrong?

• What kind of applications should a one-man software company create?

  To clarify, I already have ideas -- some of which are in progress. My question has more to do with what qualities in a piece of software makes it a good candidate for just one man to develop & maintain it. And what are some examples of successful software applications that were developed by just one man (or woman)?

• LINQ query on a DataTable

  - by Calanus

  I'm trying to perform a LINQ query on a DataTable object and bizarrely I am finding that performing such queries on DataTables is not straightforward. For example: var results = from myRow in myDataTable where results.Field("RowNo") == 1 select results; This is not allowed. Any ideas how to get something like this working? I'm amazed that LINQ queries are not allowed on DataTables!

  Could really use with some help here...

Any Ideas? Thanks!

• How to integer-divide round negative numbers *down*?

  - by Conrad Albrecht

  Seems like whenever I divide a negative int by a positive int, I need it to round down (toward -inf), not toward 0. But both C# and C++ round toward 0. So I guess I need a DivideDownward() method. I can write it in a few lines with a test for negative and so on, but my ideas seem klugey. So I'm wondering if I'm missing something and if you have an "elegant" way to round negative division downward.

• ibatis/Oracle - SELECT query inside INSERT is failing

  - by whoopy_whale

  Hi, I'm trying to do an Insert operation using iBatis. INSERT INTO SCHEMA.TABLE (FIELD1, FIELD2, FIELD3) VALUES (#field1#, (SELECT ANOTHER_FIELD FROM SCHEMA.TABLE WHERE FIELD4= #field2#), #field2#) The inner select query always fails and returns NULL. But if I substitute #field2# with the actual value only in the inner query, it works fine. Why is iBatis not substituting fieldvalues in the innerqueries? Any ideas?
