• getting the "this" that a function's caller was called with in JavaScript

  - by David Morrissey

  Is it possible to get the this that a function's caller was called with in JavaScript without passing this to the arguments in a way which supports IE as well as Firefox/Chrome et al? For example: var ob = { callme: function() { doSomething() } } function doSomething() { alert(doSomething.caller.this === ob) // how can I make this work? } ob.callme() I'm starting to suspect it's not, but I thought I may as well ask as it'd make my code much shorter and easier to read. Thanks for any information!

• Queuing methods to be run on an object by different threads in Python

  - by Ben

  Let's say I have an object who's class definition looks like: class Command: foo = 5 def run(self, bar): time.sleep(1) self.foo = bar return self.foo If this class is instantiated once, but different threads are hitting its run method (via an HTTP request, handled separately) passing in different args, what is the best method to queue them? Can this be done in the class definition itself?

• Running Java CORBA Client on Unix

  - by Benny

  I'm trying to run a Java application I wrote to subscribe to a CORBA event service. It runs OK on my Windows machine, but as soon as I deploy it to the UNIX server, it gives me an org.omg.CORBA.NO_IMPLEMENT exception. Any ideas as to why this might be happening? I'm using JacORB on my Windows machine and passing VM arguments to initialize the client ORB, but I'm not sure how to do that on UNIX and if it's even necessary. Thanks in advance!

• How do faces in .obj work?

  - by Adl

  Hi When parsing an .obj-file, with vertices and vertex-faces, it is easy to pass the vertices to the shader and the use glDrawElements using the vertex-faces. When parsing an .obj-file, with vertices and texture-coordinates, another type of face occur: texture-coordinate faces. When displaying textures, apart from loading images, binding them and passing texture coordinates into the parser, how to use the texture-coordinate faces? They differ from the vertex-faces and I suppose that the texture-coordinate faces have a purpose when displaying textures? Regards Niclas

• Is there an use case for non-blocking receive when I have threads?

  - by Gabriel Šcerbák

  I know non-blocking receive is not used as much in message passing, but still some intuition tells me, it is needed. Take for example GUI event driven applications, you need some way to wait for a message in a non-blocking way, so your program can execute some computations. One of the ways to solve this is to have a special thread with message queue. Is there some use case, where you would really need non-blocking receive even if you have threads?

• Pros and cons of escaping strategies in symfony

  - by zergu

  I am still not sure in that matter. While turned on we're quite safe but some other problems appear (with passing template variables or counting characters). On the other hand we have magic turned off, everything is clear, but we have to manually escape every variable (that come from untrusted source) in templates. By the way, non-magic solution is used in Ruby-on-Rails. So the question is: when starting a new project in symfony do you disable escaping_strategy and why?

• Is it possible to bind arrays of literals in sqlite3-ruby?

  - by willb

  I'd like to execute the following sort of query through sqlite3-ruby: SELECT * FROM foo WHERE bar IN (:items) and bind :items to one or many literals. Is this possible? The obvious technique of passing the list of literals as an array as follows doesn't seem to work: db.execute("SELECT * FROM foo WHERE bar IN (:items)", :items=>[3,1]) (In the above example, only the first value in the array is bound to :items.)

• jQuery oembed plugin z-index problem

  - by Ben

  I'm using the jQuery oembed plugin to display videos from a Vimeo feed. The only problem is they display over the top of my navigation menu. I have tried setting the z-index of the menu but this makes no difference. A common suggestion seems to be to set the wmode parameter to transparent or opaque. However, passing this as a parameter to the oembed function makes no difference. Thanks

  - by Scott B

  I've tried to code a recent posts script for my custom WP theme, however, it occurs to me that since WP ships with a recent posts widget, ideally I should just be able to call that from within my sidebar.php script, passing it the "Number of posts to show" parameter. Anyone know how to do this?

• Javascript: Inline function vs predefined functions

  - by glaz666

  Can any body throw me some arguments for using inline functions against passing predefined function name to some handler. I.e. which is better: (function(){ setTimeout(function(){ /*some code here*/ }, 5); })(); versus (function(){ function invokeMe() { /*code*/ } setTimeout(invokeMe, 5); })(); Strange question, but we are almost fighting in the team about this

• Preserving the dimensions of a slice from a Numpy 3d array

  - by Brendan

  I have a 3d array, a, of shape say a.shape = (10, 10, 10) When slicing, the dimensions are squeezed automatically i.e. a[:,:,5].shape = (10, 10) I'd like to preserve the number of dimensions but also ensure that the dimension that was squeezed is the one that shows 1 i.e. a[:,:,5].shape = (10, 10, 1) I have thought of re-casting the array and passing ndmin but that just adds the extra dimensions to the start of the shape tuple regardless of where the slice came from in the array a.

• Why is this code's execution speed so different?

  - by Steve Watkins

  In Internet Explorer 7, this code executes consistently in 47 ms: function updateObjectValues() { $('.objects').html(12345678); // ~500 DIVs } however, this code executes consistently in 157 ms: function updateObjectValues() { $('.objects').html('12345678'); // ~500 DIVs } Passing a number is over 3x faster than a string. Why are these results so dramatically different? And, is there any way to help the performance of the string?
