"Oracle MAF : TypeError: Object[object Object] has no method 'signature'",
"I am developing the mobile application using Oracle MAF.

"Reading Joystick in Windows without Pygame using Python",
"After searching for hours, I cannot seem to find a way to read a joystick's axis and buttons in Windows using Python. I don't want to use Pygame due to the fact it has a massive overhead and size. Also, the only code I could find can only read XBox controllers. I've tried using the XInput dll, but it doesn't recognize the joystick.\n\nIf anyone can point me in the right direction of what library to use, that would be great."

"Safest way to use eval to parse equations entered by a form",
"I'm wondering what sorts of things should be checked when using eval() in PHP to parse a formula that is entered by a user filling out a form. I've seen lots of answers about eval(), but not all of them seem to agree.\n\nHere's what I've gathered:\n\n\nDon't use eval for strings (this could be a problem, since it is a formula I need to parse)\nStrip the input coming from the form (I'm not entirely sure what things I need to strip)\nEval may or may not be evil, and is a security risk (are there alternatives for parsing an equation in a string?)\n\n\nWhat do you folks think I should do?\n\nEDIT: I tried the eval method, and while it does work, the sanitation I used did not support more than two operands. Since I really don't feel like writing my own (possibly insecure) sanitation regex, I'm just going to find and use a pre-written math class instead. Thanks to everyone for the suggestions!"

"Can Spring access-denied-handler refer to popup?",

"ASP.NET SqlDataSource update and create FK reference",
"The short version: \n\nI have a grid view bound to a data source which has a SelectCommand with a left join in it because the FK can be null. On Update I want to create a record in the FK table if the FK is null and then update the parent table with the new records ID. Is this possible to do with just SqlDataSources?\n\nThe detailed version:\n\nI have two tables: Company and Address. The column Company.AddressId can be null. On my ascx page I am using a SqlDataSource to select a left join of company and address and a GridView to display the results. By having my UpdateCommand and DeleteCommand of the SqlDataSource execute two statements separated by a semi-colon I am able to use the GridView's Edit and Delete functionality to update both table simultaneously.\n\nThe problem I have is when the Company.AddressId is null. What I need to have happen is have the data source create a record in the Address table and then update the Company table with the new Address.ID then proceed with the update as usual. I would like to do this with just data sources if possible for consistency/simplicity sake. Is it possible to have my data source do this, or perhaps add a second data source to the page to handle some of this?\n\nOnce I have that working I can probably figure out how to make it work with the InsertCommand as well but if you are on a roll and have an answer for how to make that fly as well feel free to provide it.\n\nThanks."

"Assign nested Product/Tuple to Array[Numeric]",

For instance I want to fill the array elements with values:\n\n// not restricted to be 4-by-2, can be abritary\n// Double will be later replaced by type T : Numeric\nvar elements = new Array[Double](4*2) \n// can contain other Numemrics as Int\nvar values = ((11.0,12.0),(21.0,22.0),(31.0,32.0), (4.0,1.0)) \n\n\nMy approach so far is\n\nvar i = 0;\nvar itRow = values.productIterator.asInstanceOf[Iterator[Product]]\nwhile(itRow.hasNext){\n var itCol = itRow.next.productIterator.asInstanceOf[Iterator[Double]]\n while(itCol.hasNext){\n elements(i) = itCol.next.asInstanceOf[Double]\n i = i + 1\n }\n}\n\n\nIt works if all entries in values are Double, but it would be nice to get this working for abritary Numerics too.\nSecond, is there a more ellegant and faster way to do this? Maybe it would be better to flatten the Tuple by\n\ndef flatProduct(t: Product): Iterator[Any] = t.productIterator.flatMap {\n case p: Product => flatProduct(p)\n case x => Iterator(x)\n} \n\n// edit: I think this is better, \n// but still the problematic if there are Int-types in values\nflatProduct(values).asInstanceOf[Iterator[Dobule]].copyToArray(elements)\n\n\nWhat to you think?\n\nThank you very much!"

"How to write a query to control a datasheet subform's combobox based on a linked table?",
"I would like my users to select from a pre-defined project list combobox in a subform. The easy way would be to use lookup fields, but I've been told to avoid those like poison. To provide context, I have two linked tables, one for User Entry, and one that stores projects.\n\nUser Entry Table\n\nPK ProjectFK Projected Hours Actual Hours\n1 1 15 13\n2 3 12 14\n3 4 13 13\n\n\nProject List Table\n\nPK ProjectName\n1 Caterpillar\n2 Omaha\n3 Dilly\n4 Holdout\n\n\nOn a separate main form, the User Entry Table serves as a datasheet subform where users select which projects they're working on, and how many hours they spend on them. Rather than having users select the project by foreign key, I was hoping the users could select the project by Project Name located in the linked table.\n\nI'm having trouble experimenting/visualizing this process. Does it involve a query, and if so, how should I go about it?\n\nThank you for your help!"

"How to resize images in pylab",
"Whenever I generate an image it very easy to zoom it manually using pylab, i.e. drawing a rectangle around the region we intend to zoom in. I was wondering if it was possible coding this operation.\n\nHere is an example code, where I generate a 100x100 image with random values on each row:\n\nfrom random import *\nfrom pylab import *\nfrom numpy import *\n\n\na=ones((100,100))\nimage=array([dummy*random() for dummy in a])\n\nimshow(image,extent=[0,1]+[5,6])\n\n\nIn the above example our image extends from 0 to 1 in the x-axis and from 5 to 6 in the y-axis. How can show a zoom on the image, let's say in the region 0.5"
