• How do I use Python's itertools.groupby()?

  - by James Sulak

  I haven't been able to find an understandable explanation of how to actually use Python's itertools.groupby() function. What I'm trying to do is this: take a list - in this case, the children of an objectified lxml element - divide it into groups based on some criteria, and then later iterate over each of these groups separately. I've reviewed the documentation (http://docs.python.org/lib/itertools-functions.html), and the examples, (http://docs.python.org/lib/itertools-example.html), but I've had trouble trying to apply them beyond a simple list of numbers. So, how do I use of itertools.groupby()? Is there another technique I should be using? Pointers to good "prerequisite" reading would also be appreciated.

• Traditional loop versus Action delegate in C#

  - by emddudley

  After learning about the Action delegate in C# I've been looking for ways I can best use it in my code. I came up with this pattern: Action<string> DoSomething = (lSomething) => { // Do something }; DoSomething("somebody"); DoSomething("someone"); DoSomething("somewhere"); If I were to have used a traditional loop, it would look something like this: List<string> lSomeList = new List<string>(); lSomeList.Add("somebody"); lSomeList.Add("someone"); lSomeList.Add("somewhere"); foreach (string lSomething in lSomeList) { // Do something } Are there any appreciable differences between the two? To me they look equally easy to understand and maintain, but are there some other criteria I might use to distinguish when one might be preferred over the other?

• What is the release date for Rakudo Star (perl6)?

  - by kbenson

  If a specific release date is not available (as I suspect it is not), can you provide resources for tracking how close it is to the desired feature set that allows release. I'm not necessarily asking for a percentage gauge, or X of Y features completed list. A list of bugs marked in whichever section of the perl RT instance that's tracking Rakudo bugs would meet my criteria, even more so if the list is dynamic (I.e. it's a list of bugs tagged in some manner, not a static list of ticket numbers). If there are only a few planned features left to be finished/tested before it's considered ready for final testing, listing those would also be sufficient.

• How to map an IDictionary<String, CustomCollectionType> in NHibernate

  - by devonlazarus

  Very close to what I'm trying to do but not quite the answer I think I'm looking for: How to map IDictionary<string, Entity> in Fluent NHibernate I'm trying to implement an IDictionary<String, IList<MyEntity>>and map this collection to the database using NHibernate. I do understand that you cannot map collections of collections directly in NHibernate, but I do need the functionality of accessing an ordered list of elements by key. I've implemented IUserCollectionType for my IList<MyEntity> so that I can use IDictionary<String, MyCustomCollectionType> but am struggling with how to get the map to work as I'd like. Details This is the database I'm trying to model: ------------------------ -------------------- | EntityAttributes | | Entities | ------------------------ ------------------ -------------------- | EntityAttributeId PK | | Attributes | | EntityId PK | <- | EntityId FK | ------------------ | DateCreated | | AttributeId FK | -> | AttributeId PK | -------------------- | AttributeValue | | AttributeName | ------------------------ ------------------ Here are my domain classes: public class Entity { public virtual Int32 Id { get; private set; } public virtual DateTime DateCreated { get; private set; } ... } public class EavEntity : Entity { public virtual IDictionary<String, EavEntityAttributeList> Attributes { get; protected set; } ... } public class EavAttribute : Entity { public virtual String Name { get; set; } ... } public class EavEntityAttribute : Entity { public virtual EavEntity EavEntity { get; private set; } public virtual EavAttribute EavAttribute { get; private set; } public virtual Object AttributeValue { get; set; } ... } public class EavEntityAttributeList : List<EavEntityAttribute> { } I've also implemented the NH-specific custom collection classes IUserCollectionType and PersistentList And here is my mapping so far: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" ...> <class xmlns="urn:nhibernate-mapping-2.2" name="EavEntity" table="Entities"> <id name="Id" type="System.Int32"> <column name="EntityId" /> <generator class="identity" /> </id> ... <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <one-to-many class="EavEntityAttributeList" /> </map> </class> </hibernate-mapping> I know the <map> tag is partially correct, but I'm not sure how to get NH to utilize my IUserCollectionType to persist the model to the database. What I'd like to see (and this isn't right, I know) is something like: <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <list> <index column="DisplayOrder"> <one-to-many class="EntityAttributes"> </list> </map> Does anyone have any suggestions on how to properly map that IDictionary<String, EavEntityAttributeList> collection? I am using Fluent NH so I'll take examples using that library, but I'm hand mappings are just as helpful here.

• The "Why" behind PMD's rules.

  - by James Kingsbery

  Is there a good resource which describes the "why" behind PMD rule sets? PMD's site has the "what" - what each rule does - but it doesn't describe why PMD has that rule and why ignoring that rule can get you in trouble in the real world. In particular, I'm interested in knowing why PMD has the AvoidInstantiatingObjectsInLoops and OnlyOneReturn rules (the first seems necessary if you need to create a new object corresponding to each object in a collection, the second seems like it is a necessity in many cases that return a value based on some criteria). Just to be clear, I know that I can disable these and how to do that, I'm just wondering why they are there in the first place. Sorry if there's something obvious I missed out there, but I did a Google search and SO search before posting this.

• Things you should implement in your own programming language

  - by I can't tell you my name.

  I've created an experimental toy programming language with a (now) working interpreter. It is turing-complete and has a pretty low-level instruction set. Even if everything takes four to six times more code and time than in PHP, Python or Ruby I still love programming all kinds of things in it. So I got the "basic" things that are written in many languages working: Hello World Input - Output Countdowns (not as easy as you think as there are no loops) Factorials Array emulation 99 Bottles of Beer (simple, wrong inflection) 99 Bottles of Beer (canonical) Conjatz conjecture Quine (that was a fun one!) Brainf*ck interpreter (To proof turing-completeness, made me happy) So I implemented all of the above examples because: They all used many different aspects of the language They are pretty interesting They don't take hours to write Now my problem is: I've run out of ideas! I don't find any more examples of what problems I could solve using my language. Do you have any programming problems which fit into some of the criteria above for me to work out?

• EF Code First - Include(x => x.Properties.Entity) a 1 : Many association

  - by VulgarBinary

  Given a EF-Code First CTP5 entity layout like: public class Person { ... } which has a collection of: public class Address { ... } which has a single association of: public class Mailbox { ... } I want to do: PersonQuery.Include(x => x.Addresses).Include("Addresses.Mailbox") WITHOUT using a magic string. I want to do it using a lambda expression. I am aware what I typed above will compile and will bring back all Persons matching the search criteria with their addresses and each addresses' mailbox eager loaded, but it's in a string which irritates me. How do I do it without a string? Thanks Stack!

• Discrete and Continuous Classifier on Sparse Data

  - by Chris S

  I'm trying to classify an example, which contains discrete and continuous features. Also, the example represents sparse data, so even though the system may have been trained on 100 features, the example may only have 12. What would be the best classifier algorithm to use to accomplish this? I've been looking at Bayes, Maxent, Decision Tree, and KNN, but I'm not sure any fit the bill exactly. The biggest sticking point I've found is that most implementations don't support sparse data sets and both discrete and continuous features. Can anyone recommend an algorithm and implementation (preferably in Python) that fits these criteria? Libraries I've looked at so far include: Orange (Mostly academic. Implementations not terribly efficient or practical.) NLTK (Also academic, although has a good Maxent implementation, but doesn't handle continuous features.) Weka (Still researching this. Seems to support a broad range of algorithms, but has poor documentation, so it's unclear what each implementation supports.)

• Finding parents where child collection does not contain an item with a specific property value

  - by Colin Bowern

  I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

• Does anyone know of a code change management tool that can highlight code changes in Visual Studio?

  - by Leejo

  Hey all, I am trying to find a tool that can highlight code changes in Visual Studio so they can be easily found and reviewed. Below are some requirements for what we are looking for... Identify and use a difference highlighting tool that meets the following criteria: • can highlight areas that need to be reviewed • there is a place to enter comments • retains line numbering from code • preference for doing within IDE Issue addressed: Hard to see what was changed in code - changes not identified. Coders do not provide administrators diffs. No tool that does a nice job to identify differences. Daunting/time consuming to provide a good diff. When highlighting differences was provided, loss of line numbers was a substantial issue (was worse).

  I have a sharepoint intranet portal which has many blogs and they have customized design. We use default Data form webpart for displaying blog posts. By default the posts are sorted based on "created date". I have a new requirement from the client asking me to change the sorting criteria to "Published date". What is the easiest method to achieve this without using SharePoint Designer . Note: Creating a new view is not a solution as I will not be able to apply the customized design.

• [change] Vlookup onto another workbook

  - by Arcadian

  Hello, here is my dilemma. I have two worksheets one that has the name of clients and one that i want to copy the names to depending on the city. For instance: associated to each column is last name, first name and city. i have hundreds of names associated to different cities and what i would like is from worksheet1.xls to copy all the New York clients to worksheet2.xls either when i open worksheet2 or via macro what ever is easier and because last name is in one cell and the first name is in the other i would have to copy both. I saw that its possible to link cells from one worksheet to another and then do a vlookup depending on the criteria. Is that the best easiest way or is there another? thanks in advance and cheers oleg

• Determining full XHR request URL on a Google Chrome XHR Breakpoint

  - by DanH

  I am initiating a jQuery ajax ($.ajax) post, within the Google Chrome browser. I have setup a XHR breakpoint in the "XHR Breakpoints" section of the "Scripts" tab within the Developer Tools. The criteria of the breakpoint is "get" ie. I want the debugger to break on all XHR requests which contain the word "get" in them (somePage.asmx/getListOfAnimals) is an example. The breakpoint is being correctly hit, however I am unable to determine what the exact URL that is being requested. I realize I can remove the breakpoint and see what URL is being requested from the "Network" tab, but I want to know this at the time the breakpoint is hit. I have tried stepping through the XHR request once it has been hit in Chrome, but I must be missing a Javascript object/property which contains the fully requested URL. Google Chrome has detected that the XHR requested URL contains "get" but how do I get to this URL from within the debug session before the request is made?

• What's the best way to view/analyse/filter huge traces/logfiles?

  - by oliver

  this seems to be a reoccurring issue: we receive a bug report for our software and with it tons of traces or logfiles. since finding errors is much easier when having a visualization of the log messages/events over time it is convenient to use a tool that can display the progression of events in a graph etc. (e.g. wireshark (http://www.wireshark.org) for analyzing network traffic) what tool do you use for such a purpose? the problem with most tools i used so far is that they mercilessly break down when you feed them huge data traces ( 1GB) so some criteria for such a tool would be: can deal with huge input files ( 1 GB) is really fast (so you don't have to get coffee while a file is loading) has some sort of filtering mechanism

• NHibernate Mapping and Querying Where Tables are Related But No Foreign Key Constraint

  - by IanT8

  I'm fairly new to NHibernate, and I need to ask a couple of questions relating to a very frequent scenario. The following simplified example illustrates the problem. I have two tables named Equipment and Users. Users is a set of system administrators. Equipment is a set of machinery. Tables: Users table has UserId int and LoginName nvarchar(64). Equipment table has EquipId int, EquipType nvarchar(64), UpdatedBy int. Behavior: System administrators can make changes to Equipment, and when they do, the UpdatedBy field of Equipment is "normally" set to their User Id. Users can be deleted at any time. New Equipment items have an UpdatedBy value of null. There's no foreign key constraint on Equipment.UpdatedBy which means: Equipment.UpdatedBy can be null. Equipment.UpdatedBy value can be = existing User.UserId value Equipment.UpdatedBy value can be = non-existent User.UserId value To find Equipment and who last updated the Equipment, I might query like this: select E.EquipId, E.EquipName, U.UserId, U.LoginName from Equipment E left outer join Users U on. E.UpdatedBy = U.UserId Simple enough. So how to do that in NHibernate? My mappings might be as follows: <?xml version="1.0" encoding="utf-8"?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="Data" assembly="Data"> <class name="User" table="Users"> <id name="Id" column="UserId" unsaved-value="0"> <generator class="native" /> </id> <property name="LoginName" unique="true" not-null="true" /> </class> <class name="Equipment" table="Equipment"> <id name="Id" column="EquipId" type="int" unsaved-value="0"> <generator class="native" /> </id> <property name="EquipType" /> <many-to-one name="UpdatedBy" class="User" column="UpdatedBy" /> </class> </hibernate-mapping> So how do I get all items of equipment and who updated them? using (ISession session = sessionManager.OpenSession()) { List<Data.Equipment> equipList = session .CreateCriteria<Data.Equipment>() // Do I need to SetFetchmode or specify that I // want to join onto User here? If so how? .List<Data.Equipment>(); foreach (Data.Equipment item in equipList) { Debug.WriteLine("\nEquip Id: " + item.Id); Debug.WriteLine("Equip Type: " + item.EquipType); if (item.UpdatedBy.Country != null) Debug.WriteLine("Updated By: " + item.UpdatedBy.LoginName); else Debug.WriteLine("Updated by: Nobody"); } } When Equipment.UpdatedBy = 3 and there is no Users.UserId = 3, the above fail I also have a feeling that the generated SQL is a select all from Equipment followed by many select columns from Users where UserId = n whereas I'd expected NHibernate to left join as per my plain ordinary SQL and do one hit. If I can tell NHibernate to do the query in one hit, how do I do that? Time is of the essence on my project, so any help you could provide is gratefully received. If you're speculating about how NHibernate might work in this scenario, please say you're not absolutely sure. Many thanks.

• Modifying generator.yml views in Symfony

  - by Alex Ciminian

  Hey! I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. list: display: [=name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ filters: [name, county_id, _status_filter, activity_id] fields: name: name: Nume Actiune indemn: name: Îndemn la actiune description: name: Descriere approved_: name: Operatiune created_at: name: Creata la status: name: Status Actiune I'm new to Symfony, so any help would be appreciated :).

• Linq and Lamba Expressions - while walking a selected list perform an action

  - by Prescott

  Hey, I'm very new to linq and lamba expressions. I'm trying to walk a collection, and when I find an item that meets some criteria I'd like to add that to another separate collection. My linq to walk the collection looks like this (this works fine): From i as MyCustomItem In MyCustomItemCollection Where i.Type = "SomeType" Select i I need each of the select items to then be added to a ListItemCollection, I know I can assign that linq query to a variable, and then do a for each loop adding a new ListItem to the collection, but I'm trying o find a way to add each item to the new ListItemcollection while walking, not a second loop. Thanks ~P

• SQL Having Clause

  - by Wally

  I'm trying to get a stored procedure to work using the following syntax: select count(sl.Item_Number) as NumOccurrences from spv3SalesDocument as sd left outer join spv3saleslineitem as sl on sd.Sales_Doc_Type = sl.Sales_Doc_Type and sd.Sales_Doc_Num = sl.Sales_Doc_Num where sd.Sales_Doc_Type='ORDER' and sd.Sales_Doc_Num='OREQP0000170' and sl.Item_Number = 'MCN-USF' group by sl.Item_Number having count (distinct sl.Item_Number) = 0 In this particular case when the criteria is not met the query returns no records and the 'count' is just blank. I need a 0 returned so that I can apply a condition instead of just nothing. I'm guessing it is a fairly simple fix but beyond my simple brain capacity. Any help is greatly appreciated. Wally

• Portable C++ library for IPC (processes and shared memory), Boost vs ACE vs Poco?

  - by user363778

  Hi, I need a portable C++ library for doing IPC. I used fork() and SysV shared memory until now but this limits me to Linux/Unix. I found out that there are 3 major C++ libraries that offer a portable solution (including Windows and Mac OS X). I really like Boost, and would like to use it but I need processes and it seems like that this is only an experimental branch until now!? I have never heard of ACE or POCO before and thus I am stuck I do not know which one to choose. I need fork(), sleep() (usleep() would be great) and shared memory of course. Performance and documentation are also important criteria. Thanks, for your Help!

• Do i *have* to use ObservableCollection in Silverlight WCF client?

  - by Simon_Weaver

  When accessing Silverlight in WCF you get proxies generated with ObservableCollection Thats fine when you're databinding, but a little clumsy when you're just calling a method. For instance the following service method : [OperationContract] public SearchOrdersMsgOut SearchOrders(ShippingStatusType[] shippingStatuses, string[] orderId) { } gets generated with ObservableCollection. What! They're just parameters. Why would I ever want to 'observe' them? I'm fine if I have to do this - but it seems like there should be a way to force simple array structures when I know I'm never databinding - especially on input messages. I'd much rather do this : searchCriteria.PaymentStatus = new [] { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; than this : searchCriteria.PaymentStatus = new ObservableCollection<PaymentStatusType> { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; Is there a way? PS. I do actually use a SearchCriteria object for my search criteria - but I simplified for this example wondering if parameters were handled differently.

• Searching a set of data with multiple terms using Linq

  - by Cj Anderson

  I'm in the process of moving from ADO.NET to Linq. The application is a directory search program to look people up. The users are allowed to type the search criteria into a single textbox. They can separate each term with a space, or wrap a phrase in quotes such as "park place" to indicate that it is one term. Behind the scenes the data comes from a XML file that has about 90,000 records in it and is about 65 megs. I load the data into a DataTable and then use the .Select method with a SQL query to perform the searches. The query I pass is built from the search terms the user passed. I split the string from the textbox into an array using a regular expression that will split everything into a separate element that has a space in it. However if there are quotes around a phrase, that becomes it's own element in the array. I then end up with a single dimension array with x number of elements, which I iterate over to build a long query. I then build the search expression below: query = query & _ "((userid LIKE '" & tempstr & "%') OR " & _ "(nickname LIKE '" & tempstr & "%') OR " & _ "(lastname LIKE '" & tempstr & "%') OR " & _ "(firstname LIKE '" & tempstr & "%') OR " & _ "(department LIKE '" & tempstr & "%') OR " & _ "(telephoneNumber LIKE '" & tempstr & "%') OR " & _ "(email LIKE '" & tempstr & "%') OR " & _ "(Office LIKE '" & tempstr & "%'))" Each term will have a set of the above query. If there is more than one term, I put an AND in between, and build another query like above with the next term. I'm not sure how to do this in Linq. So far, I've got the XML file loading correctly. I'm able to search it with specific criteria, but I'm not sure how to best implement the search over multiple terms. 'this works but far too simple to get the job done Dim results = From c In m_DataSet...<Users> _ Where c.<userid>.Value = "XXXX" _ Select c The above code also doesn't use the LIKE operator either. So partial matches don't work. It looks like what I'd want to use is the .Startswith but that appears to be only in Linq2SQL. Any guidance would be appreciated. I'm new to Linq, so I might be missing a simple way to do this. The XML file looks like so: <?xml version="1.0" standalone="yes"?> <theusers> <Users> <userid>person1</userid> <nickname></nickname> <lastname></lastname> <firstname></firstname> <department></department> <telephoneNumber></telephoneNumber> <email></email> </Users> <Users> <userid>person2</userid> <nickname></nickname> <lastname></lastname> <firstname></firstname> <department></department> <telephoneNumber></telephoneNumber> <email></email> </Users>
