• Group multiple or statements within an IF in javascript

  - by nick

  The following code works: $(".valClear").each(function () { if ($(this).val().indexOf(".png") == -1) { $(this).val(''); } }); However this doesn't (the value is removed even if it contains .png or .jpeg), what am I doing wrong? $(".valClear").each(function () { if (($(this).val().indexOf(".png") == -1) || ($(this).val().indexOf(".jpeg") == -1)) { $(this).val(''); } });

• Can you execute multiple statements in with a If statement?

  - by Jack Null

  This is my function: (defun MyFunction(input) (let ((NEWNUM (find input num))) (if (find input num) //if this (setq num NEWNUM) (FUNCT2) //then execute both of these (list 'not found)))) //else output this So after the if statment I want to be able to execute (setq num NEWNUM) and (FUNCT2).

• Is there an easily available implementation of erf() for Python?

  - by rog

  I can implement the error function, erf, myself, but I'd prefer not to. Is there a python package with no external dependencies that contains an implementation of this function? I have found http://pylab.sourceforge.net/packages/included_functions.htmlthis but this seems to be part of some much larger package (and it's not even clear which one!). I'm sorry if this is a naive question - I'm totally new to Python.

• mySQL convert varchar to date

  - by Jeff V

  I need to convert a varchar value of 1/9/2011 to a date in mySQL and I want only the month and year. So that I can then use the PERIOD_DIFF function (so I would need the above to be converted to 201101). I've tried various ways using the STR_TO_DATE function: SELECT STR_TO_DATE(CYOApp_oilChangedDate, '%m/%Y') FROM CYO_AppInfo But I get weird results... (for example: 2009-01-00) What am I doing incorrectly?

• Returning the size of available virtual memory at run-time in C++

  - by Greenhouse Gases

  In C++ is there a predefined library function that will return the size of RAM currently available on a computer a program is being run on, at run-time? For instance, if an object is 4bytes, then can we divide the available virtual memory by 4 bytes to give an estimate of how many more objects could be stored by the program safely? I have used the sizeof() function to return the size of objects within my program. Thanks

• Thread safety with heap-allocated memory

  - by incrediman

  I was reading this: http://en.wikipedia.org/wiki/Thread_safety Is the following function thread-safe? void foo(int y){ int * x = new int[50]; /*...do some stuff with the allocated memory...*/ delete x; } In the article it says that to be thread-safe you can only use variables from the stack. Really? Why? Wouldn't subsequent calls of the above function allocate memory elsewhere?

• Optimizing division/exponential calculation

  - by Saltheart

  I've inherited a Visual Studio/VB.Net numerical simulation project that has a likely inefficient calculation. Profiling indicates that the function is called a lot (1 million times plus) and spends about 50% of the overall calculation within this function. Here is the problematic portion Result = (A * (E ^ C)) / (D ^ C * B) (where A-C are local double variables and D & E global double variables) Result is then compared to a threshold which might have additional improvements as well, but I'll leave them another day any thoughts or help would be appreciated Steve

• Apply Xslt on in-memory Xml and returning in-memory Xml

  - by Jan Willem B

  I am looking for a static function in the .NET framework which takes an XML snippet and an Xslt file, applies the transformation in memory, and returns the transformed XML. I would like to do this: string rawXml = invoiceTemplateDoc.MainDocumentPart.Document.InnerXml; rawXml = DoXsltTransformation(rawXml, @"c:\prepare-invoice.xslt")); // ... do more manipulations on the rawXml Alternatively, instead of taking and returning strings, it could be taking and returning XmlNodes. Is there such a function?

• What is the purpose of using a reference to a reference in C++?

  - by SilverSun

  In my adventures studying the boost libraries, I've come across function signatures that have parameters which are a reference to a reference to an object. Example: void function(int && i); What is the purpose/benefit of doing it this way rather than simply taking a reference to an object? I assume there is one if it's in boost.

• How to compare strings ignoring case (C++)?

  - by zebraman

  I am aware there is a function strcasecmp() that compares cstrings ignoring case, but I was wondering if there is a function that does the same thing except with strings? I am working with a bunch of strings, and feel like it would be terribly inefficient to have to use c_str() each time I want to compare them with strcasecmp(). Should I just use cstrings instead of strings...?

• Mysql: Order Results by number of matching rows in Second Table.

  - by KyleT

  I'm not sure the best way to word this question so bear with me. Table A has following columns: id name description Table B has the following columns: id a_id(foreign key to Table A) ip_address date Basically Table B contains a row for each time a user views a row from Table A. My question is how do I sort Table A results, based on the number of matching rows in Table B. i.e SELECT * FROM TableA ORDER BY (SELECT COUNT(*) FROM TableB where TableB.a_id = TableA.id) Thank you!
