• Creating a list of lists with consecutive numbers

  - by Henrik

  I am looking for a convenient way to create a list of lists for which the lists within the list have consecutive numbers. So far I only came up with a very unsatisfying brute-typing force solution (yeah right, I just use python for a few weeks now): block0 = [] ... block4 = [] blocks = [block0,block1,block2,block4] I appreciate any help that works with something like nrBlocks = 4.

• How to zip multiple lists in Haskell?

  - by TheMachineCharmer

  In python zip function accepts arbitrary number of lists and zips them together. >>> l1 = [1,2,3] >>> l2 = [5,6,7] >>> l3 = [7,4,8] >>> zip(l1,l2,l3) [(1, 5, 7), (2, 6, 4), (3, 7, 8)] >>> How can I zip together multiple lists in haskell?

• Maintaining property lists for xCode projects

  - by William Jockusch

  My project currently contains two largish property lists. One is currently 20KB; another is 8KB. So far, I have been maintaining them with xCode's property list editor. This is manageable but also a bit clunky. I am wondering if other people have better ways of doing this? So far, my lists consist of nested arrays of strings. The depth is not uniform.

• In Python 3, dictionary methods no longer return lists

  - by Eric

  In python 2, keys(), values() and items() returned lists. But in Python 3, they are dynamic views and to get these dynamic views to be lists, use the list() function to convert. Ok, I get that but what the heck is a dynamic view? What is it used for? Thanks

• Prolog: How to make three lists the same lenght (by adding leading zeros)

  - by sixtyfootersdude

  I am writing a prolog program to solve a problem. The problem takes three lists as input: solve( [L|Lr] , [R|Rr] , [S|Sr] ) :- Unfortunately the lists all need to be equal length for the program to work. So these work: ?- solve( [A, B, C, D] , [1, 3, 5, 6], [E, F, G, H]). ?- solve( [1] , [2], [3]). But these do not: ?- solve( [A, B, C, D], [1], [B, I, T] ). ?- solve( [A], [1, 2], [4, 5]). What I would like to do is write a predicate(?) to pad the smaller lists with leading zeros. So: solve( [A, B, C, D], [1], [B, I, T] ) would become: solve( [A, B, C, D], [0, 0, 0, 1], [0, B, I, T] ) Any points on how to accomplish this would be awesome. I am from a functional background so I am struggling. Is there a way tell the length of a list? I think I could do that recursively, but it seems like a pain. Thanks

• weird result with c# winForms array of Lists

  - by jello

  so I'm trying to store values in an array of Lists in C# winForms. In the for loop in which I make the sql statment, everything works fine: the message box outputs a different medication name each time. for (int i = 0; i < numberOfMeds; i++) { queryStr = "select * from biological where medication_name = '" + med_names[i] + "' and patient_id = " + patientID.patient_id; using (var conn = new SqlConnection(connStr)) using (var cmd = new SqlCommand(queryStr, conn)) { conn.Open(); using (SqlDataReader rdr = cmd.ExecuteReader()) { while (rdr.Read()) { medObject.medication_date = (DateTime)rdr["patient_history_date_bio"]; medObject.medication_name = rdr["medication_name"].ToString(); medObject.medication_dose = Convert.ToInt32(rdr["medication_dose"]); medsList[i].Add(medObject); } } conn.Close(); MedicationTimelineClass medObjectx = medsList[i][0] as MedicationTimelineClass; MessageBox.Show(medObjectx.medication_name); } } but then, when I take the message box code out of the loop, meaning that the array of Lists is supposed to be populated, I always get the same value: the last value entered. the same medication name, no matter what number I put between those brackets. It's like if the whole array of Lists is populated with the same data. for (int i = 0; i < numberOfMeds; i++) { queryStr = "select * from biological where medication_name = '" + med_names[i] + "' and patient_id = " + patientID.patient_id; using (var conn = new SqlConnection(connStr)) using (var cmd = new SqlCommand(queryStr, conn)) { conn.Open(); using (SqlDataReader rdr = cmd.ExecuteReader()) { while (rdr.Read()) { medObject.medication_date = (DateTime)rdr["patient_history_date_bio"]; medObject.medication_name = rdr["medication_name"].ToString(); medObject.medication_dose = Convert.ToInt32(rdr["medication_dose"]); medsList[i].Add(medObject); } } conn.Close(); } } MedicationTimelineClass medObjectx = medsList[0][0] as MedicationTimelineClass; MessageBox.Show(medObjectx.medication_name); what's going on here?

• Ruby on Rails + Jquery: Saving data from draggable lists

  - by sjsc

  Hello. I'm trying to save data to the MySQL database in Rails when the user drags items from different lists. I'm using the below Jquery script and HTML: <script> $(document).ready(function() { $("#draggable").draggable( { connectToSortable: 'ul#myList', helper:'clone' } ); $("#myList").sortable(); }); </script> HTML: <ul> <li id="draggable">Drag me to myList</li> </ul> <ul id="myList"> <li id="item-1">item 1</li> <li id="item-2">item 2</li> </ul> I know I probably have to use something like this: $.post({ url: 'lists/update', data: $('#myList').sortable("serialize") }); I've been Googling for the last few hours but can't seem to find how to save data between multiple lists using Rails. Any idea?

• Doubly Linked Lists Implementation

  - by user552127

  Hi All, I have looked at most threads here about Doubly linked lists but still unclear about the following. I am practicing the Goodrich and Tamassia book in Java. About doubly linked lists, please correct me if I am wrong, it is different from a singly linked list in that a node could be inserted anywhere, not just after the head or after the tail using both the next and prev nodes available, while in singly linked lists, this insertion anywhere in the list is not possible ? If one wants to insert a node in a doubly linked list, then the default argument should be either the node after the to-be inserted node or node before the to-be inserted node ? But if this is so, then I don't understand how to pass the node before or after. Should we be displaying all nodes that were inserted till now and ask the user to select the node before or after which some new node is to be inserted ? My doubt is how to pass this default node. Because I assume that will require the next and prev nodes of these nodes as well. For e.g, Head<-A<-B<-C<-D<-E<-tail If Z is the new node to be inserted after say D, then how should node D be passed ? I am confused with this though it seems pretty simple to most. But pl do explain. Thanks, Sanjay

• Last parameter of last command in bash in vi-mode

  - by Mo

  I have been convinced (over at stackoverflow) to use my beloved bash in vi mode. So far I got used to it quite well and I like it. However I really do miss one feature: In emacs-mode, you can enter the last parameter of the previous command by pressing "ESC ." (That is, press escape followed by the .) Is there a default binding to insert the last parameter in vi-mode? I wasn't able to find one and I really miss this command... Thanks a lot

• Parameter based bindings in ninject 2.0

  - by Przemaas

  I want to use conditional binding in ninject, based on passed parameters. I have something like below: public class Subject { } public interface ITarget { } public class Target1 : ITarget { } public class Target2 : ITarget { } And now I need to instantiate ITarget interface: public void MethodName(IKernel kernel) { ITarget target1 = kernel.Get<ITarget>(new Parameter("name", new Subject(), true)); // Should be instance of Target1 ITarget target2 = kernel.Get<ITarget>(); // Should be instance of Target2 } I have problems to define proper bindings. I tried the following: kernel.Bind<ITarget>().To<Target1>().When(Predicate); kernel.Bind<ITarget>().To<Target2>(); private bool Predicate(IRequest request) { IParameter parameter = request.Parameters.Count == 0 ? null : request.Parameters[0]; if (parameter == null) { return false; } object parameterValue = parameter.GetValue( /*what to put here?*/); return parameterValue != null && parameterValue.GetType().IsAssignableFrom(typeof(Subject)); } but I don't know how to get value of passed parameter. I need to pass IContext instance to GetValue method, but don't know how to get valid instance of IContext. Or maybe there is better way to accomplish my task? Regards

• What exactly is a no-parameter method name?

  - by mystify

  From the Core Data docs: A property name cannot be the same as any no-parameter method name of NSObject or NSManagedObject—for example, you cannot give a property the name “description” Ok, so -description is blocked for property names. I guess it's because of KVC. But what exactly does "no-parameter" mean? Is that any method which does not take a parameter? So in other words: Any property of NSObject or NSManagedObject ANY method name of NSObject or NSManagedObject, which does not take a parameter Did I get that right?

• Where to keep a querystring parameter in session ?

  - by hoang

  Users will get to my site using a specific parameter, e.g. : http://www.mysite.com/whatever/?keepTrackOfThisValue=foo or http://www.mysite.com/who/cares/?keepTrackOfThisValue=bar I would like to store the value of this peculiar parameter in Session everytime I found it in the QueryString. I'm currently using the Session_Start event in Global.asax in order to store this but I would like to override the value each time the parameter value change, which is not possible my way. Where would you do this ?

• MDX query for SSRS2008 parameter, to be used as filter in dataset

  - by adolf garlic - SAVE BBC6MUSIC

  What I want to do: The report parameter that the user can select from is a subset of the data available in a dimension. I have a query to retrieve this subset and it works fine. I am then trying to use the selection as a filter in a dataset. In the dataset properties, you can add a parameter based on the ones you have specified on the report, but when you look in the filters pane, there seems to be no way to select this. If I try and select something in there, it creates a whole new parameter and dataset. How can I get a dataset to consume and filter by a parameter that the user has selected?

• Kerberos: Running an app with a parameter using krenew

  - by Mihai Todor

  I need to run an application with krenew, but the application also needs to receive a parameter via command line and I need to send its output to a file. From the documentation, it looks like this should do the trick: krenew -t -- sh -c 'compute-job > /afs/local/data/output' but, unfortunately, when I run the command below: krenew -s -- sh -c './my_app config.xml > results/test.txt &' the application just dies after a while and I can see from the output of ps aux that krenew is not running along with my_app. I am not sure what the parameter -t does, and as far as I can see, if I run krenew -s ./my_app, it works properly. I hope someone can clarify this.

• Ruby: Add a method to the class of an input parameter

  - by TJB

  I'm just exploring ruby and was wondering about the theoretical possibility of adding a method to the class of an object. For example, define a method that takes in a parameter and would add a method to the class of that parameter (not just to the parameter object itself). Something like this example: class SomeClass end class AnotherClass end alpha = SomeClass.new beta = AnotherClass.new def AddHelloMethodTo param # This is where I'm trying to # add a method to the class of the parameter def param.class.Hello "Hello" end end AddHelloMethodTo alpha AddHelloMethodTo beta gamma = AnotherClass.new alpha.Hello beta.Hello gamma.Hello (Excuse me if I have syntax errors / typos I'm REALLY new to this!) Notice how I don't call the AddHelloMethodTo on gamma but I expect Hello to be defined because I added it to the class. Is this possible?

• Why does UdpClient.Receive require a ref parameter?

  - by Martinho Fernandes

  Why is the parameter on UpdClient.Receive a ref parameter, instead of simply out? According to the MSDN page, the parameter is filled with the address that the datagram was sent from. However it doesn't specify what kind of input it is used for, only output.

• Puppet apache module causing 'Error 400 on SERVER: Invalid parameter identifier'

  - by Andy Shinn

  I am receiving the following error when trying to use the latest puppetlabs-apache module from github (https://github.com/puppetlabs/puppetlabs-apache): Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid parameter identifier at /etc/puppet/environments/apache_update/modules/apache/manifests/mod.pp:40 on node zordon.mydomain.com Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run My node config looks like: node 'zordon.mydomain.com' { include template::common include template::puppetagent include template::lamp User::Create sudo::conf { 'joe': priority = 60, content = 'joe ALL=(ALL) NOPASSWD: ALL', require = User::Create['joe'], } } The template::lamp class is what uses apache module: class template::lamp { include myfirewall Firewall Firewall class { 'apache': } class { 'apache::mod::php': } class { 'apache::mod::ssl': } class { 'mysql::server': } } It looks like serverfault markup is getting garbled on Puppet realize statements. The User::Create and Firewall lines are just realizing a user and 2 firewall rules. I have verified that the /var/lib/puppet/lib/puppet/type/a2mod.rb type has the identifier parameter and it is the same MD5 as the server. I am using Puppet 3.0.1 on both agent and master. Any idea what may cause this?
