  • when will ruby 1.8.6 be retired?

    - by Derick Bailey
    I can't seem to find any info on this... when will ruby 1.8.6 be 'retired'? ruby 1.8.7 is much more functional while maintaining syntax compatibility, and ruby 1.9.1 is significantly better all around... any idea when 1.8.6 will be retired?

  • Information Gain and Entropy

    - by dhorn
    I recently read this question regarding information gain and entropy. I think I have a semi-decent grasp on the main idea, but I'm curious as what to do with situations such as follows: If we have a bag of 7 coins, 1 of which is heavier than the others, and 1 of which is lighter than the others, and we know the heavier coin + the lighter coin is the same as 2 normal coins, what is the information gain associated with picking two random coins and weighing them against each other? Our goal here is to identify the two odd coins. I've been thinking this problem over for a while, and can't frame it correctly in a decision tree, or any other way for that matter. Any help? EDIT: I understand the formula for entropy and the formula for information gain. What I don't understand is how to frame this problem in a decision tree format. EDIT 2: Here is where I'm at so far: Assuming we pick two coins and they both end up weighing the same, we can assume our new chances of picking H+L come out to 1/5 * 1/4 = 1/20 , easy enough. Assuming we pick two coins and the left side is heavier. There are three different cases where this can occur: HM: Which gives us 1/2 chance of picking H and a 1/4 chance of picking L: 1/8 HL: 1/2 chance of picking high, 1/1 chance of picking low: 1/1 ML: 1/2 chance of picking low, 1/4 chance of picking high: 1/8 However, the odds of us picking HM are 1/7 * 5/6 which is 5/42 The odds of us picking HL are 1/7 * 1/6 which is 1/42 And the odds of us picking ML are 1/7 * 5/6 which is 5/42 If we weight the overall probabilities with these odds, we are given: (1/8) * (5/42) + (1/1) * (1/42) + (1/8) * (5/42) = 3/56. The same holds true for option B. option A = 3/56 option B = 3/56 option C = 1/20 However, option C should be weighted heavier because there is a 5/7 * 4/6 chance to pick two mediums. So I'm assuming from here I weight THOSE odds. I am pretty sure I've messed up somewhere along the way, but I think I'm on the right path! EDIT 3: More stuff. Assuming the scale is unbalanced, the odds are (10/11) that only one of the coins is the H or L coin, and (1/11) that both coins are H/L Therefore we can conclude: (10 / 11) * (1/2 * 1/5) and (1 / 11) * (1/2) EDIT 4: Going to go ahead and say that it is a total 4/42 increase.

  • Run SQL Queries on DataTables, or similar, in .Net, without an RDBMS

    - by FastAl
    I'd like to have a dataset or datatables, and be able to run SQL statements on them, without using any external RDBMS. For Example, to take take 2 datatables in a dataset and just join them outright with a SQL statement and Where clause, the result being a new datatable? For example if I have 2 datatables, named People and Addresses in a dataset (that I built using code, not getting from a database .. pardon the old fashioned Join syntax): dim dtJoined as DataTable = MyDataSet.RunSQLQuery ("Select * from People, Orders Where People.PersonID=Orders.OrdereID") Thanks

  • Calling and writing jquery/javascript functions

    - by Ankur
    I think I have not got the syntax correct for writing a javascript function and calling it to assign its return value to a variable. My function is: getObjName(objId){ var objName =""; $.ajax( { type : "GET", url : "Object", dataType: 'json', data : "objId="+objId, success : function(data) { objName = data; } }); return objName; } I am trying to call it and assign it to a variable with: var objName = getObjName(objId); However Eclipse is telling me that "the function getObjName(any) is undefined"

  • How to quote and reference MS SQL table and field names

    - by artvolk
    Good day! Despite the fact LINQ2SQL and ADO.NET Entity Framework exists there were situations when I need to revert to plain old DataSet (not typed) and friends. While writing SQL for SqlCommand: Is it needed to quote field and table names with []? Is it good to prefix table names with [dbo] I use to use this syntax: SqlCommand command = new SqlCommand("SELECT [Field1], [Field2] FROM [dbo].[TableName]", connection); May be there is a better way? Thanks in advance!

  • IgnoreArguments including an Action<T>

    - by James L
    I'm probably missing something obvious here, so apologies in advance! Using Rhino Mocks, how do I set an expectation that a method taking an Action will be called, but I want to use IgnoreArguments. Obviously I can't specify null as that isn't an Action, and I dont want any meaningless code in the test. As I said, it's probably obvious by the syntax is eluding me at the moment!

  • vim adding new function names for project's API

    - by Flavius
    Hi How can I add new function names for .c and .h files to be highlighted, similar to this http://stackoverflow.com/questions/2464593/custumizing-syntax-highlighting-in-vim but much easier? (as I don't need to color words in different colors, only in the default color for keywords as defined by my theme). I need this to add highlighting for function names in a project written in C which has a clearly defined API. Thanks

  • Switch Statement in C#

    - by pm_2
    Does anyone know if it's possible to include a range in a switch statement (and if so, how)? For example: switch (x) { case 1: //do something break; case 2..8: //do something else break; default: break; } The compiler doesn't seem to like this kind of syntax - neither does it like: case <= 8:

  • Make a Button Appear Focused When Not

    - by Bret
    The Find and Replace dialog in Visual Studio is a perfect example of what im trying to accomplish. Notice how the "Find what" text field has keyboard focus but the "Find Next" button appears bluish as if it has keyboard focus also even though it does not. How can I accomplish this myself? I've tried messing with FocusManager and Focus Scopes without much luck. I suspect i may be barking up the wrong tree? Any advice is appreciated! Thanks

    - by Leif Andersen
    If you look at the following line of python code: bpy.ops.object.particle_system_add({"object":bpy.data.objects[2]}) you see that in the parameters there is something enclosed in braces. Can anyone tell me what the braces are for (generically anyway)? I haven't really seen this type of syntax in python and I can't find any documentation on it. Any help is greatly appreciated. Thank you.
