• zen of Python vs with statement - philosophical pondering

  - by NeuronQ

  I don't intend to simply waste your time, but: has it occurred to you too, while using Python's with statement that it really is contrary to the 5th line of "The Zen of Python" that goes "Flat is better than nested"? Can any enlightened Python guru share me some of their insights on this? (I always find that one more level of indentation pops up in my code every time I use with instead of f.close()... and it's not like I'm not gonna use try: ... finally: ... anyways and thus the benefits of with still elude me, even as I grow to like and understand Python more and more...)

• Does C# have an equivalent to Scala's structural typing?

  - by Tom Morris

  In Scala, I can define structural types as follows: type Pressable { def press(): Unit } This means that I can define a function or method which takes as an argument something that is Pressable, like this: def foo(i: Pressable) { // etc. The object which I pass to this function must have defined for it a method called press() that matches the type signature defined in the type - takes no arguments, returns Unit (Scala's version of void). I can even use the structural type inline: def foo(i: { def press(): Unit }) { // etc. It basically allows the programmer to have all the benefits of duck typing while still having the benefit of compile-time type checking. Does C# have something similar? I've Googled but can't find anything, but I'm not familiar with C# in any depth. If there aren't, are there any plans to add this?

• EJB3 with Spring

  - by fish

  I have understood that if I use EJB in Spring context, I get all the same benefits as if I was using it in "pure" EJB3 environment, is this true? I have googled but can't find a definitive, clear answer. For example, let's say I have a session bean that updates some tables in the database and it throws a System Exception. In "pure" EJB3 environment the transaction is rolled back. What if I for example @Autowire this bean using Spring, does Spring take care of the transaction handling same way as does the EJB3 container? Or what? Does it maybe require some specific configuration or is it fully "automatic"?

• avr-gcc Atmel AVR microncontrollers on Linux / Windows Arduino IDE

  - by Prakash

  I recently heard all about avr-gcc and avr-lib support on Linux that can be used for developing code for Atmel AVR micro-controller (ATmega48/88/168, ATmega16/32). I also understand that Arduino also uses Atmel's AVR micro-controller (I am not sure which one). Now different vendors have designed their own product (using Atmel AVR uc) where code is to be developed using avr-gcc i.e. on Linux platform. In the same regards Arduino's Windows IDE is much simpler and easy to code with. I am confused as to which platform is more promising - what are the benefits of learning avr-gcc? Which is the better option to program using the same? What type of application can we develop using avr-gcc compiler?

• Whats the significance of named scope in rails?

  - by piemesons

  Before going for details. Question 1:-- Whats the meaning of scope here (ie named scope)? whats the benefits of using named scope? Now:- from agile development with rails book:-- class Order < ActiveRecord::Base named_scope :last_n_days, lambda { |days| {:conditions => ['updated < ?' , days] } } named_scope :checks, :conditions => {:pay_type => :check} end Such a named scope would make finding the last weeks worth of orders a snap. orders = Orders.last_n_days(7) Scopes can also be combined orders = Orders.checks.last_n_days(7) why we are using named_scope here. We can do the same using methods. Whats special thing we got using named_scope.

• Why darcs instead of git?

  - by Ctrl Alt D-1337

  Using pure functional languages can have a lot of benefits over using impure imperatives but low level systems languages will generally allow you to achieve much greater performance especially when they are imperative because it allows you to specify the exact steps in how the cpu should compute the result. If there is ever list of tools where high performance is an absolute must then I would put source version controls systems right at the top of that list and git achieves this very well but performance is not it's only advantage over many other other types of version control systems anyway. The git team are handling the unsafe c code very well and I never worry about my type system or any other features of the language it is written in so why is it that there is a lot of haskell developers that must use darcs when they will only be using the finished product?

• Imports and Depends

  - by David Diez

  I have read two recent posts that discuss Depends and Imports but I have four lingering, related questions: Suppose I want two packages to also be available to the end-user when they load in my package. Is there a good reason not to use Depends in this context? (The point here is to load all three packages via a command that loads just the one package.) Is it okay to specify a package in both the Depends and Imports fields? If a package is listed in Depends, is there a point to also listing it in Imports? Or are the benefits of Imports already negated by using Depends? [Added Question] Is the following correct? A package should be listed in the Imports field of the DESCRIPTION file if and only if the package is imported (in whole or in part) in the NAMESPACE file. Thanks much! David

• Verifying the purchaser of an App Store application

  - by Keldi

  Is there a way for the developer of an App Store application to tie a sale to an individual user/device ID/Apple account? In other words, a method for the developer to double-check that a specific user has legally purchased the software? I haven't been able to find a reliable answer to this yet. I'm not looking for specific code examples, just some sort of idea as to how possible (or difficult) this is. My intent isn't to penalize piracy; it's to be able to provide additional benefits to paid customers. As such, I'm not looking for a way to identify a cracked or pirated version, which I gather has already been solved. Thanks in advance for any help you can provide!

• MLS Integration (RETSBond RI or?)

  - by prodigitalson

  I'm looking Specifically for some detailed information on RETSBond Integrator (RI) or something similar. Has anyone used it? Drawbacks? benefits? What I need is something that provides a PHP API out of the box or some kind of RPC exposure. This thing seems to provide an API for batching the MLS server and putting in my own DB which is acceptable although ideally I'd prefer something totally external. Do any MLS services provide that that you are aware of? I realize this is somewhat subjective but I'm looking for a starting point on different services/vendors to research.

• Initialize Pointer Through Function

  - by SoulBeaver

  I was browsing my teacher's code when I stumbled across this: Order* order1 = NULL; then order1 = order(customer1, product2); which calls Order* order(Customer* customer, Product* product) { return new Order(customer, product); } This looks like silly code. I'm not sure why, but the teacher initialized all pointers to NULL instead of declaring them right away(looking at the code it's entirely possible, but he chose not to). My question is: is this good or acceptable code? Does the function call have any benefits over calling a constructor explicitely? And how does new work in this case? Can I imagine the code now as kind of like: order1 = new Order(customer, product);

• Best Design pattern for social media file transfer

  - by Onema

  Our system would like our clients to link their accounts with different social media sites like youtube, vimeo, facebook, myspace and so on. One of the benefits we would like to give to the user is to transfer, update and delete files they have uploaded to our sites and transfer them to the social media sites mentioned above. this files could be videos, images or audio. We started thinking about using a strategy pattern, as all of these sites share a common process ( authentication, connection, use the API to transfer/edit/delete the file ), but we soon realized that it may not work as me may want to use some of the extended functionality that is specific to each service (eg: associate a youtube video with a channel, or upload images to a specific album on facebook, and much, much more...) My question is, what would be the best Structural Design Patter to use for this scenario?

• Is Oracle AQ/Streams of any use in my situation?

  - by RenderIn

  I'm writing a workflow system that is driven entirely at each step by explicit human interaction. That is, a task is assigned to a person, that person selects from a few limited options {approve, reject, forward}, and then it is either sent along to the next person or terminated. Just curious of Oracle Streams/AQ has anything to offer over flat tables managed by regular web application code. The amount of processing after each action is fairly limited and the volume is not terribly high, so there's not really a need to throttle things by throwing them into a queue. What are some of the benefits of introducing a queue structure, or is it overkill for my situation?

• Current state of client-side XSLT

  - by Casey

  Last I heard, Blizzard was one of the few companies to put client-side XSLT into practice (2008). Is this still the case in 2011, or are more people now exploring this technique in production?  It seems that modern browsers (IE9, FF4, Chrome) and client processing power are primed to exploit this standard for tangible savings in server CPU power and bandwidth on large scale properties. Am I missing something? The negative aspects I'm aware of include * additional rendering time * additional assets required on uncached page load * additional layer of complexity * noticably less developer experience than server-side template techniques The benefits I perceive include * distributed template composition (offloaded on the client) * caching of common template fragments offloaded on the client * logical separation of document structure and data * well-documented web standard supported by all modern browsers Finally, although I know it's impossible to predict the future, I am curious to know opinions on whether or not client-side XSLT's day will come. With interest in HTML5 driving users to upgrade their browsers and developers to explore new techniques, I would say yes. How about you? Thanks in advance, Casey

• Typescript + requirejs: How to handle circular dependencies?

  - by Aymeric Gaurat-Apelli

  I am in the process of porting my JS+requirejs code to typescript+requirejs. One scenario I haven't found how to handle is circular dependencies. Require.js returns undefined on modules that are also dependent on the current and to solve this problem you can do: MyClass.js define(["Modules/dataModel"], function(dataModel){ return function(){ dataModel = require("Modules/dataModel"); ... } }); Now in typescript, I have: MyClass.ts import dataModel = require("Modules/dataModel"); class MyClass { dataModel: any; constructor(){ this.dataModel = require("Modules/dataModel"); // <- this kind of works but I lose typechecking ... } } How to call require a second time and yet keep the type checking benefits of typescript? dataModel is a module { ... }

• I wanted to be a programmer

  - by Henrik P. Hessel

  Hello, let me ask your opinion. I'm 25 now, living in Germany. I started with QBASIC, did some Java in Highschool, and after School I created some Websites in PHP. Now, because my Company is Microsoft Gold Partner, I've to use Microsoft all the time. C#, MSSQL, ASPX and Sharepoint <- I really hate it! So, in my spare I concentrate to gain more knowledge (C++, Java, Silverlight or WPF), because it feels that I'm so far behind, in comparison for example to you guys, or other older employees in my company. Do think that my behaviour is useful? Should I focus my time to become i.e. a pure C# Programmer? I did C# even before I started to learn some C++. Should I learn what do with pointers, memcpy and stuff like that, even if managed code brings us so much benefits? Or is it a waste of time, better invested in learning the latest technologies? rAyt

• Why Use PHP OOP over Basic Functions and When?

  - by Codex73

  There are some posts about this matter, but I didn't clearly get when to use Object Oriented coding and when to use programmatic functions in an include. Somebody also mentioned to me that OOP is very heavy to run, and makes more workload. Is this right? Lets say I have a big file with 50 functions, why will I want to call these in a class? and not by function_name(). Should I switch and create object which holds all of my functions? What will be the advantage or specific difference? What benefits does it bring to code OOP in php ? Modularity?

• Cannot sort a row of size 8130, which is greater than the allowable maximum of 8094

  - by Sri Kumar

  Hello All, SELECT DISTINCT tblJobReq.JobReqId, tblJobReq.JobStatusId, tblJobClass.JobClassId, tblJobClass.Title, tblJobReq.JobClassSubTitle, tblJobAnnouncement.JobClassDesc, tblJobAnnouncement.EndDate, tblJobAnnouncement.AgencyMktgVerbage, tblJobAnnouncement.SpecInfo, tblJobAnnouncement.Benefits, tblSalary.MinRateSal, tblSalary.MaxRateSal, tblSalary.MinRateHour, tblSalary.MaxRateHour, tblJobClass.StatementEval, tblJobReq.ApprovalDate, tblJobReq.RecruiterId, tblJobReq.AgencyId FROM ((tblJobReq LEFT JOIN tblJobAnnouncement ON tblJobReq.JobReqId =tblJobAnnouncement.JobReqId) INNER JOIN tblJobClass ON tblJobReq.JobClassId = tblJobClass.JobClassId) LEFT JOIN tblSalary ON tblJobClass.SalaryCode = tblSalary.SalaryCode WHERE (tblJobReq.JobClassId in (SELECT JobClassId from tblJobClass WHERE tblJobClass.Title like '%Family Therapist%')) When i try to execute the query it results in the following error. Cannot sort a row of size 8130, which is greater than the allowable maximum of 8094 I checked and didn't find any solution. The only way is to truncate (substring())the "tblJobAnnouncement.JobClassDesc" in the query which has column size of around 8000. Do we have any work around so that i need not truncate the values. Or Can this query be optimised? Any setting in SQL Server 2000?

• What's the reason for leaving an extra blank line at the end of a code file?

  - by Lord Torgamus

  Eclipse and MyEclipse create new Java files with an extra blank line after the last closing brace by default. I think CodeWarrior did the same thing a few years back, and that some people leave such blank lines in their code either by intention or laziness. So, this seems to be at least a moderately widespread behavior. As a former human language editor -- copy editing newspapers, mostly -- I find that those lines look like sloppiness or accidents, and I can't think of a reason to leave them in source files. I know they don't affect compilation in C-style languages, including Java. Are there benefits to having those lines, and if so, what are they?

• Good reasons to migrate PHP libraries to namespaces

  - by Joseph Mastey

  I have a significant number of object libraries written for PHP 5.2.5, and I'm trying to weigh the benefits of retrofitting them for namespaces. I don't have any concerns about the server PHP version at the moment, since any relevant machines are under my control, so I'm not worried about backwards compatibility. As far as the structure of the libraries, I use the same convention as Zend Framework, (Library_Module_Class_Name e.g.) so I don't currently have any naming conflicts internal to the libraries. I'd anticipate moving the Library and Module parts of those classnames to namespaces. That said, if the code is already written, is there any good reason to move over to namespaces? Thanks, Joe

• Possible to view T-SQL syntax of a stored proc-based SqlCommand?

  - by mconnley

  Hello! I was wondering if anybody knows of a way to retrieve the actual T-SQL that is to be executed by a SqlCommand object (with a CommandType of StoredProcedure) before it executes... My scenario involves optionally saving DB operations to a file or MSMQ before the command is actually executed. My assumption is that if you create a SqlCommand like the following: Using oCommand As New SqlCommand("sp_Foo") oCommand.CommandType = CommandType.StoredProcedure oCommand.Parameters.Add(New SqlParameter("@Param1", "value1")) oCommand.ExecuteNonQuery() End Using It winds up executing some T-SQL like: EXEC sp_Foo @Param1 = 'value1' Is that assumption correct? If so, is it possible to retrieve that actual T-SQL somehow? My goal here is to get the parsing, etc. benefits of using the SqlCommand class since I'm going to be using it anyway. Is this possible? Am I going about this the wrong way? Thanks in advance for any input!

• Why might SQL execute more quickly on SQL Server 2000 when NOT using a stored procedure?

  - by Kofi Sarfo

  I could see nothing wrong with the execution plan. Besides, as I understand it, SQL Server 2000 extended many of the performance benefits of stored procedures to all SQL statements by recognising new T-SQL statements against T-SQL statements of existing execution plans (by retaining execution plans for all SQL statements in the procedure cache, not just stored procedure execution plans) It's a fairly straight forward SELECT statement with sensible table joins, no transactions included or linked servers being referenced within the query and WITH (NOLOCK) table hints applied. The stored procedure was created by dbo and the user has all the necessary permissions. So my question is this: What are the likely reasons for a query to take only a few seconds to run but then take several minutes when identical T-SQL is run via a stored procedure?

• Is System.AddIn mostly about making it easier to use Remoting or does it make it harder to do so?

  - by MatthewMartin

  It takes at least 7 assemblies and restricting my AddIn's data model to data types that remoting can deal with before the appdomain isolation features begin to work. It is so complex! The System.AddIn teams blog implies to me they were trying to re-create a mental model of COM, a model I never understood very well in the first place and am not sold on the benefits. (If COM is so good why's it dead?-rhetorical question.) If I don't need to mirror or interop with legacy COM (like VSTO does using System.AddIn), is it possible to just create some classes that load load in a new AppDomain? I can write the discovery code my self, I've done it before and a naive implementation is pretty fast because I'm not like iterating over the assemblies in the GAC! So my specific question is, can I get the AppDomain isolation that AddIns provide with a few code Remoting snippets, and what would those be?

• Is it considered a good/bad practice to configure tomcat for deploying certain apps?

  - by Roman

  Disclaimer: I've never used technique which is described below. That's why there may occur some mistakes or misunderstandings in its description. I heard that some teams (developers) use 'pre-configured' tomcat. As I understand they add different jars to tomcat \lib folder and do something else. Once I've read something about recompilation (or reassembly?) of tomcat for certain needs. Just yesterday I heard a dialog where one developer sayd that his team-mates were not able to deploy the project until he would give them configured tomcat version. So, I wonder, what is it all about and why do they do it? What benefits can they gain from that?
