• What guides or standards do you use for version control in your team ?

  - by PaulHurleyuk

  I'm starting to do a small amount of development within my company. I'm intending to use Git for version control, and I'm interested to see what guidelines or standards people are using around version in their groups, similar to coding standards are often written within the group for the group. I'm assuming there will be things like; Commit often (at least every day/week/meeting etc) Release builds are always made from the master branch Prior to release, a new branch will be created for Testing and tagged as such. only bug fixes from this point onwards. The final release of this will be tagged as such and the bug fixes merged back into the trunk Each developer will have a public repo New features should get their own branch Obviously a lot of this will depend on what cvs you're using and how you've structured it.

• Should my internal API classes be all in one package?

  - by Chris

  I'm hard at work packaging up an API for public consumption. As such I'm trying to limit the methods that are exposed to only those that I wish to be public and supportable. Underneath this of course there are a multitude of limited access methods. The trouble is that I have a lot of internal code that needs to access these restricted methods without making those methods public. This creates two issues: I can't create interfaces to communicate between classes as this would make these my internal methods public. I can't access protected or default methods unless I put the majority of my internal classes in the same package. So, I have around 70 or 80 internal classes in cleanly segregated packages BUT with overly permissive access modifiers. Would you say that a single package is the lesser of two evils or is there a better way to be able to mask my internal methods whilst keeping more granular packages? I'd be interested to find out the best practice here. I'm already aware of This

• Custom User Management for Google App Engine Java

  - by Gopi

  I am using GAE Java for a multi-user application. There are multiple users with different roles. Each user can login, do some operations and logout. The business restricts me from using Google User Service and I need to implement my own for authentication and session management. Can anyone please share with me how should I go about implementing my own user management? I have read its very tricky to implement own user management. Any pointers in terms of best approaches/ design / existing frameworks if any ? I could see some similar posts but they are for python.

• Style of if: to nest or not to nest

  - by Marco

  A colleague of mine and me had a discussion about the following best-practice issue. Most functions/methods start with some parameter checking. I advocate the following style, which avoids nesting. if (parameter one is ugly) return ERROR; if (parameter two is nonsense || it is raining) return ERROR; // do the useful stuff return result; He, who comes from a more functional/logic programming background, prefers the following, because it reduces the number of exit points from the function. if (parameter one is ok) { if (parameter two is ok && the sun is shining) { // do the useful stuff return result } } return ERROR; Which one would you prefer and why?

• Writing a custom iterator -- what to do if you're at the end of the array?

  - by Goose Bumper

  I'm writing a custom iterator for a Matrix class, and I want to implement the increment method, which gets called when the iterator is incremented: void MatrixIterator::increment() { // go to the next element } Suppose the iterator has been incremented too many times and now points to past the end of the matrix (i.e. past the one-past-the-end point). What is the best practice for this situation? Should I catch this with an assert, or should I just say it's the user's responsibility to keep track of where the iterator is pointing and it's none of my business?

• Can anyone recommend a primer to Erlang?

  - by Till

  I've recently found myself getting more and more interested in Erlang. I've purchased a book (Programming in Erlang) and started reading up on the basics. Reading books is time consuming so I am looking to shortcut this a bit and go back to the book later. What I lack is a good introductory tutorial. Kind of like, hands on, this is what you need to get started in Erlang, these are best practices, this is how you organize code and this is how you do a small project. I've googled this topic extensively and haven't had much luck. ;)

• Communication between layers in an application

  - by Petar Minchev

  Hi guys! Let's assume we have the following method in the business layer. What's the best practice to tell the UI layer that something went wrong and give also the error message? Should the method return an empty String when it was OK, otherwise the error message, or should it throw another exception in the catch code wrapping the caught exception? If we choose the second variant then the UI should have another try,catch which is too much try,catch maybe. Here is a pseudocode for the first variant. public String updateSomething() { try { //Begin transaction here dataLayer.do1(); dataLayer.do2(); dataLayer.doN(); } catch(Exception exc) { //Rollback transaction code here return exc.message; } return ""; } Is this a good practice or should I throw another exception in the catch(then the method will be void)?

• R: simple and short if clauses for combind statements

  - by jorgusch

  Hello, TRUE/FALSE if clauses are easily and quickly done in R. However, if the argument gets more complex, it also gets ugly very soon. For instance: I might want to execute different operations for a row(foo) dependent on the value in one cell (foo[1]). Let the intervals be 0:39 and 40:59 and 60:100 Something like does not exit: (if foo[1] "in" 40:60){... In fact, I only see ways of at least two if clauses and two else statements and the action for the first interval somewhere at the bottom of the code. With more intervals(or any other condition) it is getting more complex. Is there a best practice (for this purpose or others) with a simple construction and nice design to read? Thanks a lot!

• C# Async call garbage collection

  - by Troy

  Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? internal MyClass { public void OnMyButtonClicked() { var wcfClient = new WcfClient(); wcfClient.SomeMethodFinished += OnMethodCompleted; wcfClient.SomeMethodAsync(); } private void OnMethodCompleted(object sender, EventArgs args) { //Do something with the result //After this method does the subscription to the event //fall out of scope for garbage collection? } } Will I run into problems if I call the function again and create another subscription? Thanks in advance to anyone who responds.

• Converting a constantly changing scalar value to a changing interval or frequency

  - by eco_bach

  Although I'm coding in Objective C, this is more of a general programming question. What is the best way to convert a constantly changing scalar value to a changing interval or frequency? Right now every time the scalar value changes I am destroying the NSInterval ie [self.myTimer invalidate]; self.myTimer = nil; and creating a new one, but this seems like a VERY expensive way to achieve my goal, since the changing scalar value in my case represents the horizontal velocity of a swipe. For a rough analogy, think of the speed of a swipe being reflected in a visual metronome, the faster you swipe, the higher(shorter interval) the frequency of the metronome.

• Passing HttpFileCollectionBase to the Business Layer - Bad?

  - by Terry_Brown

  hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

• SQL Server: Mitigating schema changes/upgrades

  - by bradhe

  I haven't spent a ton of time researching this yet, mostly looking for best practices on upgrading/changing DB schemas. We're actively developing a new product and as such we often have additions or changes to our DB schema. We also have many copies of the DB -- one for the test environment, one for the prod environment, dev environments, you name it. We don't really want to have to blow away test data every time we want to make a change to the DB. Are there good ways of automating this or handling this? None of us have really ever had to deal with this so...

• What is a good practice to access class attributes in class methods?

  - by Clem

  I always wonder about the best way to access a class attribute from a class method in Java. Could you quickly convince me about which one of the 3 solutions below (or a totally different one :P) is a good practice? public class Test { String a; public String getA(){ return this.a; } public setA(String a){ this.a = a; } // Using Getter public void display(){ // Solution 1 System.out.println(this.a); // Solution 2 System.out.println(getA()); // Solution 3 System.out.println(this.getA()); } // Using Setter public void myMethod(String b, String c){ // Solution 1 this.a = b + c; // Solution 2 setA(b + c); // Solution 3 this.setA(b + c); } }

• Debugging a Browser Redirect Loop

  - by just_wes

  Hi all, I am using CakePHP with the Auth and ACL components. My page loads fine for non-registered users, but if I try to log in as a registered user I get an infinite redirect loop in the browser. I am sure that this is some sort of permissions problem, but the problem exists even for users who have permissions for everything. The only way to prevent this behavior is to allow '*' in my AppController's beforeFilter method. What is the best way to debug this sort of problem? Thanks!

• Sharing a database connection with included classes in a Sinatra application

  - by imightbeinatree

  I'm converting a part of a rails application to its own sinatra application. It has some beefy work to do and rather than have a million helps in app.rb, I've separated some of it out into classes. Without access to rails I'm rewriting finder several methods and needing access to the database inside of my class. What's the best way to share a database connection between your application and a class? Or would you recommend pushing all database work into its own class and only having the connection established there? Here is what I have in in app.rb require 'lib/myclass' configure :production do MysqlDB = Sequel.connect('mysql://user:password@host:port/db_name') end I want to access it in lib/myclass.rb class Myclass def self.find_by_domain_and_stub(domain, stub) # want to do a query here end end I've tried several things but nothing that seems to work well enough to even include as an example.

• Is it a good idea to keep documentation in the VCS?

  - by Jj

  At work we just moved to Mercurial for our VCS from SVN. In SVN we used to have a "docs" folder next to "trunk", in "docs" we would keep all our file documentation, client files, diagrams, mockups, etc. (we use a wiki(Redmine) for internal documentation). Now in a DVCS enviroment we don't need a "trunk" folder, so we drop the code at the root of the repo, and now having a "docs" folder inside the repo feels weird being at the same level that the code. This has taken me to reconsider if it is a good idea to keep those files in the VCS, we have a "documents" section in Redmine, but I have never used it because it is a pain to have to download a file each time I want to open it and I can't access the file when I'm offline. What best practices have you guys found to manage these kind of non-code files?

• ArgumentException or ArgumentNullException for string parameters?

  - by Anna Lear

  Far as best practices are concerned, which is better: public void SomeMethod(string str) { if(string.IsNullOrEmpty(str)) { throw new ArgumentException("str cannot be null or empty."); } // do other stuff } or public void SomeMethod(string str) { if(str == null) { throw new ArgumentNullException("str"); } if(str == string.Empty) { throw new ArgumentException("str cannot be empty."); } // do other stuff } The second version seems more precise, but also more cumbersome than the first. I usually go with #1, but figured I'd check if there's an argument to be made for #2.

• In ASP.NET MVC Should A Form Post To Itself Or Another Action?

  - by Sohnee

  Which of these two scenario's is best practice in ASP.NET MVC? 1 Post to self In the view you use using (Html.BeginForm) { ... } And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Edit(EditModel model) 2 Post from Edit to Save In the view you use using (Html.BeginForm("Save", "ControllerName")) { And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Save(EditModel model) Summary I can see the benefits of each of these, the former gives you a more restful style, with the same address being used in conjunction with the correct HTTP verb (GET, POST, PUT, DELETE and so on). The latter has a URL schema that makes each address very specific. Which is the correct way to do this?

• In .NET which loop runs faster for or foreach

  - by Binoj Antony

  In c#/VB.NET/.NET which loop runs faster for or foreach? Ever since I read that for loop works faster than foreach a long time ago I assumed it stood true for all collections, generic collection all arrays etc. I scoured google and found few articles but most of them are inconclusive (read comments on the articles) and open ended. What would be ideal is to have each scenarios listed and the best solution for the same e.g: (just example of how it should be) for iterating an array of 1000+ strings - for is better than foreach for iterating over IList (non generic) strings - foreach is better than for Few references found on the web for the same: Original grand old article by Emmanuel Schanzer CodeProject FOREACH Vs. FOR Blog - To foreach or not to foreach that is the question asp.net forum - NET 1.1 C# for vs foreach [Edit] Apart from the readability aspect of it I am really interested in facts and figures, there are applications where the last mile of performance optimization squeezed do matter.

• Decimal rounding strategies in enterprise applications

  - by Sapphire

  Well, I am wondering about a thing with rounding decimals, and storing them in DB. Problem is like this: Let's say we have a customer and a invoice. The invoice has total price of $100.495 (due to some discount percentage which is not integer number), but it is shown as $100.50 (when rounded, just for print on invoice). It is stored in the DB with the price of $100.495, which means that when customer makes a deposit of $100.50 it will have $0.005 extra on the account. If this is rounded, it will appear as $0, but after couple of invoices it would keep accumulating, which would appear wrong (although it actually is not). What is best to do in this case. Store the value of $100.50, or leave everything as-is?

• Should HTTP POST be discouraged?

  - by Tomas Sedovic

  Quoting from the CouchDB documentation: It is recommended that you avoid POST when possible, because proxies and other network intermediaries will occasionally resend POST requests, which can result in duplicate document creation. To my understanding, this should not be happening on the protocol level (a confused user armed with a doubleclick is a completely different story). What is the best course of action, then? Should we really try to avoid POST requests and replace them by PUT? I don't like that as they convey a different meaning. Should we anticipate this and protect the requests by unique IDs where we want to avoid accidental duplication? I don't like that either: it complicates the code and prevents situations where multiple identical posts may be desired.

• TFS Automated Builds to Code Packages

  - by Adam Jenkin

  I would like to hear the best practices or know how people perform the following task in TFS 2008. I am intending on using TFS for building and storing web applications projects. Sometimes these projects can contain 100's of files (*.cs, *.acsx etc) During the lifetime of the website, a small bug will get raised resulting in say a stylesheet change, and a change to default.aspx.cs for example. On checking in these changes to TFS, and automated build would be triggered (great!), however for deploying the changes to the target production machine, I only need to deploy for example: style.css default.asx MyWebApplications.dll So my question is, can MSBuild be customized to generate a "code pack" of only the files which require deploying to the production server based on the changeset which cause the re-build?

• How to insert an n:m-relationship with technical primary keys generated by a sequence?

  - by bitschnau

  Let's say I have two tables with several fields and in every table there is a primary key which is a technical id generated by a database sequence: table1 table2 ------------- ------------- field11 <pk> field21 <pk> field12 field22 field11 and field21 are generated by sequences. Also there is a n:m-relationship between table1 und table2, designed in table3: table3 ------------- field11 <fk> field21 <fk> The ids in table1 und table2 are generated during the insert statement: INSERT INTO table1 VALUES (table1_seq1.NEXTVAL, ... INSERT INTO table2 VALUES (table2_seq1.NEXTVAL, ... Therefore I don't know the primary key of the added row in the data-access-layer of my program, because the generation of the pk happens completely in the database. What's the best practice to update table3 now? How can I gain access to the primary key of the rows I just inserted?

• How to synchronize static method in java.

  - by Summer_More_More_Tea

  Hi there: I come up with this question when implementing singleton pattern in Java. Even though the example listed blow is not my real code, yet very similar to the original one. public class ConnectionFactory{ private static ConnectionFactory instance; public static synchronized ConnectionFactory getInstance(){ if( instance == null ){ instance = new ConnectionFactory(); } return instance; } private ConnectionFactory(){ // private constructor implementation } } Because I'm not quite sure about the behavior of a static synchronized method, I get some suggestion from google -- do not have (or as less as possible) multiple static synchronized methods in the same class. I guess when implementing static synchronized method, a lock belongs to Class object is used so that multiple static synchronized methods may degrade performance of the system. Am I right? or JVM use other mechanism to implement static synchronized method? What's the best practice if I have to implement multiple static synchronized methods in a class? Thank you all! Kind regards!

• PHP explode and set to empty string the missing pieces

  - by Marco Demaio

  What's the best way to accomplish the following. I have strings in this format: $s1 = "name1|type1"; //(pipe is the separator) $s2 = "name2|type2"; $s3 = "name3"; //(in some of them type can be missing) Let's assume namen/typen are strings and they can not contain a pipe. Since I need to exctract the name/type separetly, I do: $temp = explode($s1, '|'); $name = $temp[0]; $type = ( isset($temp[1]) ? $temp[1] : '' ); Is there an easier (smarter whatever faster) way to do this without having to do isset($temp[1]) or count($temp). Thanks!
