• htaccess mod rewrite changes http://www to http:/www

  - by Nir

  I want to replace calls like this: www.mysite.com/sub/file.php?param1=x&param2=http://www.someurl.com with: www.mysite.com/sub/param1/param2 Param 1 is an integer number Param 2 is a url I wrote this rewrite rule in htaccess: RewriteCond %{REQUEST_URI} \/sub\/ RewriteRule sub\/([0-9]+)\/(.*)$ sub\/file.php?param1=$2&param2=$1 [L] Unfortunately param2 (the URL) starts with http:/www.someurl.com instead of http://www.someurl.com (note the single slash). Any idea what causes it? When I call the same file with same parameters in the format www.mysite.com/sub/file.php?param1=x&param2=http://www.someurl.com , param2 does appear OK so it must be something with the rewrite rule.

• newbie question -- how does one override show for a newtype?

  - by gatoatigrado

  I want to override the default integer constructors in Haskell so they produce strings (mostly for curiosity, but temporarily to make a nice input alternative for LaTeX's \frac{}{} inconvenience). I wanted to be able to use the language itself, instead of a special parser, but I guess that's probably not going to work out... module Main where import Prelude hiding ((+)) newtype A = A Int deriving (Eq, Show, Num) default (A) (+) :: A -> (A -> String) (A a) + (A b) = (show a) ++ " + " ++ (show b) main2 = 3+4 main :: IO () main = putStrLn main2 The problem with the above is that the + function only works for (A, A) instead of (A, String), etc. If one simply leaves out the pattern match "(A a)" and writes "a" instead, then the show() function prepends "A " so "3" becomes "A 3" instead of just "3". I want to override Show for A, but it seems to be quite a headache...

• Specify which row to return on SQLite Group By

  - by lozzar

  I'm faced with a bit of a difficult problem. I store all the versions of all documents in a single table. Each document has a unique id, and the version is stored as an integer which is incremented everytime there is a new version. I need a query that will only select the latest version of each document from the database. While using GROUP BY works, it appears that it will break if the versions are not inserted in the database in the order of version (ie. it takes the maximum ROWID which will not always be the latest version). Note, that the latest version of each document will most likely be a different number (ie. document A is at version 3, and document B is at version 6). I'm at my wits end, does anybody know how to do this (select all the documents, but only return a single record for each document_id, and that the record returned should have the highest version number)?

• Multidimensional arrays in VB.NET 2010

  - by matt_t

  Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python). Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case? e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]] Apologies for the poor explanation but I cannot think of any better ways to explain.

• Boost Mersenne Twister: how to seed with more than one value?

  - by Eamon Nerbonne

  I'm using the boost mt19937 implementation for a simulation. The simulation needs to be reproducible, and that means storing and potentially reusing the RNG seeds later. I'm using the windows crypto api to generate the seed values because I need an external source for the seeds and not because of any particular guarantees of randomness. The output of any simulation run will have a note including the RNG seed - so the seed needs to be reasonably short. On the other hand, as part of the analysis of the simulation, I'll be comparing several runs - but to be sure that these runs are actually different, I'll need to use different seeds - so the seed needs to be long enough to avoid accidental collisions. I've determined that 64-bits of seeding should suffice; the chance of a collision will reach 50% after about 2^32 runs - that probability is low enough that the average error caused by it is negligible to me. Using just 32-bits of seed is tricky; the chance of a collision reaches 50% already after 2^16 runs; and that's a little too likely for my tastes. Unfortunately, the boost implementation either seeds with a full state vector - which is far, far too long - or a single 32-bit unsigned long - which isn't ideal. How can I seed the generator with more than 32-bits but less than a full state vector? I tried just padding the vector or repeating the seeds to fill the state vector, but even a cursory glance at the results shows that that generates poor results.

• can't update rails model

  - by Tristan

  Hi there, I'm rather new to rails. I have a controller that's attempting to update a model using the following code: @test = Product.find(1) @test.increment!(:price) It does successfully retrieve the Product from the database, but does not update the price attribute. Does anyone know why this might be the case, or how I could get more feedback on what the problem is? Thanks a bunch! Tristan edit: price is an integer with value 0. I get the same problem when I set the price with @test.price=50 and then @test.save .

• How to model "target day" in UML Classdiagrams

  - by Tobiask

  Hi there, I want to describe the following situation in an UML Classdiagram: A day, on which a newspaper is send to a customer. This day could be sth. like "every friday" or "every first day of a month". My idea to represent this in a UML Classdiagram: -targetDay:Integer -targetDayGrid:Enumeration targetDay would be sth. like "1" (for monday) oder "5" (for friday) or it could be "1" for the first day of the month or "10" for the 10th day of the month. targetDayGrid is an enum: weekly, monthly. So the enum sets the semantic meaning of the number in targetDay. I´m not happy with this, do you know any other solution to represent my problem? Or do you think my solution is okay?

• Need Simple way to access XML in VB.Net - Pain with Linq-to-Xml

  - by aiart

  Dim myXDoc As XDocument = _ I want to access this in a simple way in VB.Net - Like: Dim Integer SizeXStr = CInt(MyZDoc.Cameras(1).Camera_Desc.@SizeX) ' where (1) is an index Why isn't this implemented in VB.Net? Better yet, type the values with a Schema and eliminate the conversion. Is this so hard? How do I access, in a simple way, data in XML - this would be VERY VERY useful! I have been using Query to try to get the values - when I use MsgBox() to display results, they display, but my main Windows Form is Trashed - changed colors, etc. The system has Bugs. Instead, I have to create an elaborate structure of arrays of objects and read the XML line-by-line and do the same for saving - this is the dark ages. Art

• MySQL index cardinality - performance vs storage efficiency

  - by Sean

  Say you have a MySQL 5.0 MyISAM table with 100 million rows, with one index (other than primary key) on two integer columns. From my admittedly poor understanding of B-tree structure, I believe that a lower cardinality means the storage efficiency of the index is better, because there are less parent nodes. Whereas a higher cardinality means less efficient storage, but faster read performance, because it has to navigate through less branches to get to whatever data it is looking for to narrow down the rows for the query. (Note - by "low" vs "high", I don't mean e.g. 1 million vs 99 million for a 100 million row table. I mean more like 90 million vs 95 million) Is my understanding correct? Related question - How does cardinality affect write performance?

• How to configure Multi-tenant plugin as single-tenant with Spring security plugin as resolver?

• Error while Installing Android app on Android virtual device

  - by Priyank

  Hi. I have created a small and simple android app. I tried installing it on an actual android device. But because it won't install, I created an AVD resembling my phone. I tried copying and installing app on that AVD and it still says that error. "Application xxx could not be installed on this phone". Before I tried installing my app on the phone or AVD I following steps: 1. Exported an unsigned copy of application onto my hard-drive. 2. User jarsigner to sign the app 3. Verified with jarsigner that my app is signed properly. 4. Used zipalign to optimize the app resources. I do not have an icon assigned to myapp but mandatory properties like version etc. have been specified properly. I had initially developed app using 2.1 version but because of compatability issues with my phone I reverted code to compile on 1.5 and it still doesn't get installed either on AVD or my phone. My AVD is on 2.1 though and code is compiled with 1.5. Is there a place where I can see the logs as to why app is not getting installed. It would be really helpful. Cheers

• PLT Scheme Extracting field ids from structures

  - by Steve Knight

  I want to see if I can map PLT Scheme structure fields to columns in a DB. I've figured out how to extract accessor functions from structures in PLT scheme using the fourth return value of: (struct-type-info) However the returned procedure indexes into the struct using an integer. Is there some way that I can find out what the field names were at point of definition? Looking at the documentation it seems like this information is "forgotten" after the structure is defined and exists only via the generated-accessor functions: (<id>-<field-id> s). So I can think of two possible solutions: Search the namespace symbols for ones that start with my struct name (yuk); Define a custom define-struct macro that captures the ordered sequence of field-names inside some hash that is keyed by struct name (eek).

Is there a quicker way? Speed seems to be a bit slow on it as it pulls down the entire feed before parsing.

• gettype and unknown type in php

  - by justjoe

  i just start to practice with php built-in, gettype() and its return value. This function is capable to return testing result such as boolean, integer, unknown type, etc. But among those testing result, there's one caught my eyes : unknown type. After reading gettype, and try to find some reference here, i can not get any. So, the question is what kind of type can be categorized as "unknown type" ? is it possible ? or am i just missing reading something ?

• NSInteger differences between CLI and GUI ?

  - by d11wtq

  I've been building a framework and writing unit tests in GHUnit. One of my Framework's accessor methods returns an NSInteger. I assert the expected value in the tests like this: GHAssertEquals(1320, request.port, @"Port number should be 1320"); When running my tests with an AppKit UI based frontend this assertion passes. However, when I run my tests on the command line, it fails with a type-mismatch unless I type-cast my hard-coded 1320 as (NSInteger). What's causing the difference in the way the integer is being interpreted by the compiler? Is xcodebuild on the command line using a different data-type for hard coded integers?

• Create a polynomial object from a number using change-class

  - by charlieb

  I have written a polynomial class along the lines described in SICP 2.5.3 (except using defclass). I would like to be able to seamlessly add and multiply polynomials and regular numbers but I can't make change-class accept a number. I tried to simplify the problem by changing class from an integer to a float: (change-class 4 'float) but that gave me the error: There is no applicable method for the generic function #<STANDARD-GENERIC-FUNCTION CHANGE-CLASS (7)> when called with arguments (4 #<BUILT-IN-CLASS FLOAT>). [Condition of type SIMPLE-ERROR] I get an error of the same form from (fyi): (change-class 4 'polynomial) I'm going to go ahead and implement a manual conversion but I would prefer to use the built-in clos facilities.

• Int or NSInteger as object for method argument. Objective-C

  - by sergiobuj

  Hi. I'm having some trouble passing a number as an argument for a method: -(void) meth2:(int)next_int; And to call that method i need this: int next_int = 1; [self performSelectorOnMainThread:@selector(meth2:) withObject:next_int waitUntilDone:NO]; //update next_int and call meth2 again at this point i get a "pointer from integer without a cast" error, and would happen the same with a NSInteger. A NSNumber is not useful because it's immutable and i need to change the value constantly. Any Idea how can i do this? Thanks.

• Databinding int32 to MaskedEditExtender enabled TextBox

  - by Zach Skinner

  I have a master/detail scheme for editing an asp:GridView using an asp:DetailsView. One of my fields is for a phone number of type int64 (always 10 digits). I would like this field to always be displayed as (###)###-####. My issue is the first digit in the phone number is always truncated for my edit item field which I used a MaskedEditExtender to achieve the formatting. Here is my EditItemTemplate for the details view: <cc1:MaskedEditExtender TargetControlID="edtPROJ_Leader_Phone" Mask="(999)999-9999" runat="server" ClearMaskOnLostFocus="false" ClipboardEnabled="true" MaskType="Number" /> <asp:TextBox ID="edtPROJ_Leader_Phone" runat="server" Text='<%# Bind("PROJ_Leader_Phone") %>' ></asp:TextBox> When my details view is displayed for editing, the text box displays(_23)456-7890 for the integer 1234567890. Also worth noting that if the property MaskType="Number" is removed, the textbox shows: (234)567-890_. I would of course have the textbox show (123)-546-67890 after binding.

• Create new field in a table that already exists - flex/air sqlite?

  - by Adam

  I've got a flex/air app I've been working on, it uses a local sqlite database that is created on the initial application start. I've added some features to the application and in the process I had to add a new field to one of the database tables. My questions is how to I go about getting the application to create one new field that is located in a table that already exists? this is a the line that creates the table stmt.text = "CREATE TABLE IF NOT EXISTS tbl_status ("+"status_id INTEGER PRIMARY KEY AUTOINCREMENT,"+" status_status TEXT)"; And now I'd like to add a status_default field. thanks! Thanks - MPelletier I've add the code you provided and it does add the field, but now the next time I restart my app I get an error - 'status_default' already exists'. So how can I go about adding some sort of a IF NOT EXISTS statement to the line you provided?

• SQL Server 2000 tables

  - by klork

  We currently have an SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: Does anyone have any experience with a SQL Server (2000/2005) installation with millions of tables? What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

• Algorithm question.

  - by Lukasz Lew

  I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach.
