• Common Ancestor to Java Array and List

  - by Phuong Nguyen de ManCity fan

  In .NET, both array and list have Enumerable as ancestor, so a method that accept Enumerable as an argument can receive both array and list as its argument. I wonder if there is a similar thing in Java?

• Creating a function that will handle objects with common properties

  - by geocine

  Take this as an example I have trimmed this example for readability and you may not find the use of this concept here. class Teacher() { public Name {get; set;} public Salt {get; set;} public Department{get; set;} } class Student() { public Name {get; set;} public Salt {get; set;} public Section{get; set;} } public string GetEncryptedName(object Person) { //return encrypted name based on Name and Salt property return encrypt(object.Salt,object.Name) } callig the function GetEncryptedName(Teacher) GetEncryptedName(Student) How do you implement this kind of stuff?

• Dealing with &rest-parameters in common lisp

  - by Patrick

  I want define a functions that accepts &rest - parameters and delegates them to another function. (html "blah" "foo" baz) = "blahfoobaz" I did not find a better way than this one: (defun html (&rest values) (concatenate 'string "" (reduce #'(lambda(a b) (concatenate 'string a b)) values :initial-value "") "")) But this looks somewhat glumbsy to me, since line 4 does no more than concatenating the &rest parameter "values". I tried (concatenate 'string "" (values-list values) "") but this does not seem to work (SBCL). Could someone give me an advice? Kind regards

• What is the most common way to use a middleware in node with express and connect

  - by Bernhard

  Thinking about the correct way, how to make use of middlewares in a node.js web project using express and connect which is growing up at the moment. Of course there are middlewares right now wich has to pass or extend requests globally but in a lot of cases there are special jobs like prepare incoming data and in this case the middleware would only work for a set of http-methods and routes. I've a component based architecture and each component brings it's own middleware layer which can implement those for requests this component can handle. On app startup any required component is loaded and prepared. Is it a good idea to bind the middleware code execution to URLs to keep cpu load lower or is it better to use middlewares only for global purposes? Here's some dummy how an url related middleware look like. app.use(function(req, res, next) { // Check if requested route is a part of the current component // or if the middleware should be passed on any request if (APP.controller.groups.Component.isExpectedRoute(req) || APP.controller.groups.Component.getConfig().MIDDLEWARE_PASS_ALL === true) { // Execute the midleware code here console.log('This is a route which should be afected by middleware'); ... next(); }else{ next(); } });

• What are the common patterns in web programming?

  - by lankerisms

  I have been trying to write my first big web app (more than one cgi file) and as I kept moving forward with the rough prototype, paralelly trying to predict more tasks, this is the todo that got accumulated (In no particular order). * Validations and input sanitizations * Object versioning (to avoid edit conflicts. I dont want hard locks) * Exception handling * memcache * xss and injection protections * javascript * html * ACLs * phonetics in search, match and find duplicates (for form validation) * Ajaxify!!! (I have snipped off the project specific items.) I know that each todo will be quite tied up to its project and technologies used. What I am wondering though, is if there is a pattern in your todo items as well as the sequence in which you experienced guys have come across them.

• Refactoring common method header and footer

  - by David Wong

  I have the following chunk of header and footer code appearing in alot of methods. Is there a cleaner way of implementing this? Session sess = factory.openSession(); Transaction tx; try { tx = sess.beginTransaction(); //do some work ... tx.commit(); } catch (Exception e) { if (tx!=null) tx.rollback(); throw e; } finally { sess.close(); } The class in question is actually an EJB 2.0 SessionBean which looks like: public class PersonManagerBean implements SessionBean { public void addPerson(String name) { // boilerplate // dostuff // boilerplate } public void deletePerson(Long id) { // boilerplate // dostuff // boilerplate } }

• mysql get table based on common column between two tables

  - by Zentdayn

  while trying to learn sql i came across "Learn SQL The Hard Way" and i started reading it. Everything was going fine then i thought ,as a way to practice, to make something like given example in the book (example consists in 3 tables pet,person,person_pet and the person_pet table 'links' pets to their owners). I made this: report table +----+-------------+ | id | content | +----+-------------+ | 1 | bank robbery| | 2 | invalid | | 3 | cat on tree | +----+-------------+ notes table +-----------+--------------------+ | report_id | content | +-----------+--------------------+ | 1 | they had guns | | 3 | cat was saved | +-----------+--------------------+ wanted result +-----------+--------------------+---------------+ | report_id | report_content | report_notes | +-----------+--------------------+---------------+ | 1 | bank robbery | they had guns | | 2 | invalid | null or '' | | 3 | cat on tree | cat was saved | +-----------+--------------------+---------------+ I tried a few combinations but no success. My first thought was SELECT report.id,report.content AS report_content,note.content AS note_content FROM report,note WHERE report.id = note.report_id but this only returns the ones that have a match (would not return the invalid report). after this i tried adding IF conditions but i just made it worse. My question is, is this something i will figure out after getting past basic sql or can this be done in simple way? Anyway i would appreciate any help, i pretty much lost with this. Thank you. EDIT: i have looked into related questions but havent yet found one that solves my problem. I probably need to look into other statements such as join or something to sort this out.

And 1 table for each derived class. 3 tables have same columns. How can I create mapping file ignoring base class? Do I need to create 1 mapping file for each derived class? can I achieve this using only 1 mapping file?

• intrusive_ptr: Why isn't a common base class provided?

  - by Jon

  intrusive_ptr requires intrusive_ptr_add_ref and intrusive_ptr_release to be defined. Why isn't a base class provided which will do this? There is an example here: http://lists.boost.org/Archives/boost/2004/06/66957.php, but the poster says "I don't necessarily think this is a good idea". Why not?

• An algorithm to find common edits

  - by Tass

  I've got two word lists, an example: list 1 list 2 foot fuut barj kijo foio fuau fuim fuami kwim kwami lnun lnun kizm kazm I'd like to find o ? u # 1 and 3 i ? a # 3 and 7 im ? ami # 4 and 5 This should be ordered by amount of occurrences, so I can filter the ones that don't appear often. The lists currently consist of 35k words, the calculation should take about 6h on an average server.

• SQL most executed query?

  - by Esabe

  Hi everyone, I have a database in SQL Server 2008, and there are a lot of machines making queries against it. I know there is a SQL Server profiler, but I don't know very well how to use it. Is there any way to know what are the most common queries executed in the database? Through the profiler or not, it doesn't matter. Thank you very much in advance!

• What is the difference between 1 and '1 in Lisp?

  - by Jason Baker

  I had never really thought about whether a symbol could be a number in Lisp, so I played around with it today: > '1 1 > (+ '1 '1) 2 > (+ '1 1) 2 > (define a '1) > (+ a 1) 2 The above code is scheme, but it seems to be roughly the same in Common Lisp and Clojure as well. Is there any difference between 1 and quoted 1?

• Programming DataEntry&Forms: Population of Official Common Data Lists

  - by rlb.usa

  As a programmer of data-entry forms of all kinds, I often find myself making fields for things like Country and State. Consider: Perhaps a list the 50 United States names is an easy thing to find (does one include DC?) , but the countries are not. Nearly every site you find has a differing list with all of the political goings on over the years, and they become outdated quickly. What's the best practice regarding population of these kinds of lists? Is there an official list somewhere that one uses to populate these kinds of formal/official fields? Where do you get this data from, when it's not exactly specified in the specs?

• Django: common template subsections

  - by Parand

  What's a good way to handle commonly occurring subsections of templates? For example, there is a sub-header section that's used across 4 different pages. The pages are different enough to not work well with template inheritance (ie. "extends" doesn't fit well). Is "include" the recommended method here? It feels a bit heavyweight, requiring each subsection or snippet to be in its own file. Are there any performance issues in using include or is it smart about forming template from the subsections (ie. if I make extensive use of it, do I pay any penalties)? I think what I'm looking for is something like template tags, but without the programming - a simple way to create a library of html template tags I can sprinkle in other templates.

• Best loose way to get objects with common base class

  - by Michael Teper

  I struggled to come up with a good title for this question, so suggestions are welcome. Let's say we have an abstract base class ActionBase that looks something like this: public abstract class ActionBase { public abstract string Name { get; } public abstract string Description { get; } // rest of declaration follows } And we have a bunch of different actions defined, like a MoveFileAction, WriteToRegistryAction, etc. These actions get attached to Worker objects: public class Worker { private IList<ActionBase> _actions = new List<ActionBase>(); public IList<ActionBase> Actions { get { return _actions; } } // worker stuff ... } So far, pretty straight-forward. Now, I'd like to have a UI for setting up Workers, assigning Actions, setting properties, and so on. In this UI, I want to present a list of all available actions, along with their properties, and for that I'd want to first gather up all the names and descriptions of available actions (plus the type) into a collection of the following type of item: public class ActionDescriptor { public string Name { get; } public string Description { get; } poblic Type Type { get; } } Certainly, I can use reflection to do this, but is there a better way? Having Name and Description be instance properties of ActionBase (as opposed to statics on derived classes) smells a bit, but there isn't an abstract static in C#. Thank you!

  - by govardhan

  We have two applications. One application in .asp and second application in java. we want to build interface for universal authentication, so that one can access the other application once signed into one application. Both applications are using SQL database, but one is written in .ASP hosted on Windows server while the other is in JAVA hosted on a Linux server. The applications are currently resided on two different servers. requirements: 1)The end user are most likely to access the applications through .ASP first, then reach the 2nd application more like "back office" management system. 2)he JAVA application currently works well with IE web browser, but not very smooth with other browsers such as Firefox. Would like to make the application to be more compatible with other browsers. Please help me, its very important to me. Thanks in advance!

• delete common dictionaries in list based on a value

  - by pythoonatic

  How would I delete all corresponding dictionaries in a list of dictionaries based on one of the dictionaries having a character in it. data = [ { 'x' : 'a', 'y' : '1' }, { 'x' : 'a', 'y' : '1/1' }, { 'x' : 'a', 'y' : '2' }, { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, ] For example, how would I delete all of the x = a due to one of the y in the x=a having a / in it? Based on the example data above, here is where I would like to get to: cleaneddata = [ { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, ]

• Listing all objects that share a common variable in Javascript

  - by ntgCleaner

  I'm not exactly sure how to ask this because I am just learning OOP in Javascript, but here it goes: I am trying to be able to make a call (eventually be able to sort) for all objects with the same variable. Here's an example below: function animal(name, numLegs, option2, option3){ this.name = name; this.numLegs = numLegs; this.option2 = option2; this.option3 = option3; } var human = new animal(Human, 2, example1, example2); var horse = new animal(Horse, 4, example1, example2); var dog = new animal(Dog, 4, example1, example2); Using this example, I would like to be able to do a console.log() and show all animal NAMES that have 4 legs. (Should only show Horse and Dog, of course...) I eventually want to be able to make a drop-down list or a filtered search list with this information. I would do this with php and mySQL but I'm doing this for the sake of learning OOP in javascript. I only ask here because I don't exactly know what to ask. Thank you!

• Several modules in a package importing one common module

  - by morpheous

  I am writing a python package. I am using the concept of plugins - where each plugin is a specialization of a Worker class. Each plugin is written as a module (script?) and spawned in a separate process. Because of the base commonality between the plugins (e.g. all extend a base class 'Worker'), The plugin module generally looks like this: import commonfuncs def do_work(data): # do customised work for the plugin print 'child1 does work with %s' % data In C/C++, we have include guards, which prevent a header from being included more than once. Do I need something like that in Python, and if yes, how may I make sure that commonfuncs is not 'included' more than once?

• Recursive only 2 level records using common sql

  I have an Employee table, it's a self-referencing table, with managerId refers to primary key empID. I want to find 2 level records by a given empId. For example: if given empId=5, if empId=5 has children records, display them, as well as the children in children records. You may also provide a recursive suggestion without level limitation. The database is SQL Server 2005.
