• Function that converts hex color values to an approximate color name?

  - by dclowd9901

  I don't suppose anyone knows of a function (PHP, preferably) that can take a hex color code and give an approximate color name for that hex value. I don't need a solution with 100s of colors. Even if it just amounted to the colors white, black, red, green blue, brown orange and yellow, I'd be pretty well in shape. If you don't know of an existing resource, does anyone know of a good way to approach this problem? Thanks in advance for the help.

• Sequential numbering from recursive function? e.g. 2, 2.1, 2.1.1, 2.2, 2.2.1

  - by Pete

  I have a recursive function reading a "table of contents" of documents from a database. I would like to print numbering with the document that reflects where the item is in the tree, e.g. First item, 1.1 Child of first item, 1.1.1 Child of child of first item, 1.2 Child of first item, Second item, 2.1 Child of second item, etc. Rather stumped about this at the moment - help please?

• Getting ORA Oracle error code using PHP function oci_connect?

  - by me_here

  The PHP function oci_connect (which connects to an Oracle database) just returns false if it fails, which at the moment I handle like this: $connection = oci_connect($username, $password, $database); if (!$connection){ return $result = "Trouble connecting to the Oracle Database"; } But really I'd like to have the actual ORA error code, so I can be more informative. Is this possible?

• Is there a way to set a handler function for when a set of events has happened?

  - by allyourcode

  eg I have two concurrent AJAX requests, and I need the result from both to compute a third result. I'm using the Prototype library, so it might look something like this: var r1 = new Ajax.Request(url1, ...); var r2 = new Ajax.Request(url2, ...); function on_both_requests_complete(resp1, resp2) { ... } One way would be to use polling, but I'm thinking there must be a better way.

• What is the simplest way (or simplest library) to create a truly secure php mail() function?

  - by Tchalvak

  The mail() function is bad, because it is so permissive with headers that you pretty much can't use it with any user input without subjecting yourself or others to spam. So what is the simplest substitute that can still ensure that it's use is secure? Ideally something that can be included in an external file.

• Most inappropriate function or variable names you have encountered?

  - by Andrioid

  I was reading through my daily doze of RSS when I noticed a link to the python compiler documentation where class names like assList, assName and assTuple exist. While starting names with 'ass' is perfectly acceptable to me, it just sparked this idea that there probably exist much better examples of this. Have you personally used or otherwise encountered any inappropriate function or variable names? Personally I have used 'crap' and 'moo' for temporary purposes, forgot them and at a later point they came too integrated for me to bother with fixing them.

• How do I create and read non-global variables that aren't destroyed at end of function?

  - by Paul Reilly

  I am attempting to code some plugins to use with MIDI sequencers but have hit a stumbling block. I can't use global-scope variables to store information because multiple instances of the .dll can exist which share memory. How do I create a class (for re-usability purposes in other plugins) containing 2 dimensional array and other variables the content of which is to be shared between functions? If that is possible, how would I read and write the data from the function in the framework where I do the processing?

• Jython: is there a clean way to implement a Java interfaces with function references?

  - by auramo

  I know that I can implement a Java interface with Jython like this: class MyListener (Listener): def foo(self, event): print(str(event)) Python has first-class functions so that seems like an overkill - especially for interfaces with one method. Is there a way to just pass a lambda or function which implements a single method in an interface instead?

• Can one construct a "good" hash function using CRC32C as a base.

  - by DavidD

  Given that SSE 4.2 (Intel Core i7 & i5 parts) includes a CRC32 instruction, it seems reasonable to investigate whether one could build a faster general-purpose hash function. According to this only 16 bits of a CRC32 are evenly distributed. So what other transformation would one apply to overcome that? David
