• DCVS + hosting for a startup commercial multiplatform phone app

  - by AG

  I'm in lean startup mode, working on a simple phone app that will be published initially as a iThingy app and an Android app with, possibly, Blackberry and Symbian versions to follow. I'm about to go from no repository to needing a central repository that up to 4 very part-time resources will be sharing. Two of us have no version control background, one has used Subversion, and I've used most of the major centralized VCS systems. I'm not going to be pushing the technical limitations of any VCS for a long time; I'm sure that any of the major systems would work fine. And the hosting accounts I've looked at seem reasonable. So I'm really focussed on minimizing the downside risks. That is, I'd like to find a stable setup that is easy to learn in general, easy to use from Windows/Eclipse, and won't paint me into any obvious corners for the next 12 months or so. A quick search of the web had led me to consider the following pairs of DVCS and hosting service, with what I think I'm hearing as their strengths and weaknesses (for my purposes): Bazaar/Launchpad -- My initial choice since I need to get more familiar with this pair for the Google Summer of Code mentoring I'm doing. But, whatever the technical merits, a non-starter for me because they are purely open source, no private repositories plans to purchase that I can see. Git/GitHub -- Git: Fast, light, ultimately flexible, but relatively less Windows friendly, Eclipse plugin (eGit) available but relatively young, GitHub: widely used, pricing is fine Mercurial/BitBucket -- Mercurial: a little less flexible, a little more Windows friendly, Eclipse plugin seems a bit more mature, BitBucket: widely used, pricing is fine, includes a wiki and an issue tracker that we might be able to use instead of something like BaseCamp, at least for a while. Mercurial/BitBucket seem like the winning pair so far for my particular situation; at least two of us are definitely going to be working mostly from Eclipse on Windows and reducing my own learning curve is a priority. ;-) But I have two specific questions: 1) Am I wrong about Bazaar/Launchpad and is there a viable, secure way to use them for proprietary code? 2) Any reason to think that the Mecurial/Bitbucket pair will end up being a headache for my Mac developer, soon, or for Blackberry or Symbian developers a little later? ag

• deployment public keys

  - by hyperboreean

  How do you guys deploy your code on your servers? I am using Fabric and Python and I would like a more automated way of pulling code from the repository through the use of public keys, but without any ops or manual intervention to set up the public keys. Are you storing them in the code as text or in a database and generate the pk file on the fly?

• Drawing lattices online

  - by lavabo

  This isn't really a programming question but... Is there any way to draw online a lattice for a material, like a compound? i.e. a 3D gridlike pattern? I know there are some applications for drawing mathematical lattices, but the notation to me is unfamiliar - are there simply programs or applets or something for drawing lattices like in a compound?

• Where do you keep your code?

  - by skiphoppy

  Your code is of course checked into a repository somewhere, but where do you keep your working copy/copies? C:\Program Files isn't right, as it's for installed packages. My Documents somehow doesn't seem right, either—a My Code folder next to My Music and My Pictures? Dumping in C:\ is messy, but seems to be "working" for other people in my office.

• taglib with constants functionality?

  - by jack

  I need to use some constants in my JSP. Now I'd like to use this without using scriptlets. (and adding getters is not an option, it's an external jar) Using the search I've seen that some people put them in a map. However I've seen that there's a constants function in the unstandard taglib but that is a few years old and so far I haven't found a maven repository with it. So are there any other taglibs with this functionality?

• Naming Unit Tests that just calls a constructor?

  - by Thomas Jespersen

  I'm trying to follow Roy Osherove's UnitTests naming convention, with the naming template: [MethodName_StateUnderTest_ExpectedBehavior]. Following this pattern. How would you name a test calling a constructor? [Test] public void ????() { var product = new Product(); Assert.That(product, Is.Not.Null); }

• Are there any drawbacks to class-based Javascript injection?

  - by jonathanconway

  A phenomena I'm seeing more and more of is Javascript code that is tied to a particular element on a particular page, rather than being tied to kinds of elements or UI patterns. For example, say we had a couple of animated menus on a page: <ul id="top-navigation"> ... </ul> <!-- ... --> <ul id="product-list"> ... </ul> These two menus might exist on the same page or on different pages, and some pages mightn't have any menus. I'll often see Javascript code like this (for these examples, I'm using jQuery): $(document).ready(function() { $('ul#top-navigation').dropdownMenu(); $('ul#product-selector').dropdownMenu(); }); Notice the problem? The Javascript is tightly coupled to particular instances of a UI pattern rather than the UI pattern itself. Now wouldn't it be so much simpler (and cleaner) to do this instead? - $(document).ready(function() { $('ul.dropdown-menu').dropdownMenu(); }); Then we can put the 'dropdown-menu' class on our lists like so: <ul id="top-navigation" class="dropdown-menu"> ... </ul> <!-- ... --> <ul id="product-list" class="dropdown-menu"> ... </ul> This way of doing things would have the following benefits: Simpler Javascript - we only need to attach once to the class. We avoid looking for specific instances that mightn't exist on a given page. If we remove an element, we don't need to hunt through the Javascript to find the attach code for that element. I believe techniques similar to this were pioneered by certain articles on alistapart.com. I'm amazed these simple techniques still haven't gained widespread adoption, and I still see 'best-practice' code-samples and Javascript frameworks referring directly to UI instances rather than UI patterns. Is there any reason for this? Is there some big disadvantage to the technique I just described that I'm unaware of?

• SelectList in Asp-mvc and data from the database

  - by George

  Hello guys. I'm having some troubles with SelectList in ASP.MVC. Here is the issue: I have a Create View and begind a ViewModel model. The page load just fine (GET verb). But when posting, something happens, and my model is considered invalid, and it cannot insert. Here's what i've tried so far. public class DefinitionFormViewModel { private Repository<Category> categoryRepository = new Repository<Category>(); public Definition ViewDefinition { get; private set; } public SelectList Categories { get; private set; } public DefinitionFormViewModel(Definition def) { ViewDefinition = def; // here i wanted to place it directly, like shown in NerdDinner Tutorial // new SelectList(categoryRepository.All(),ViewDefinition.Category); Categories = new SelectList(categoryRepository.All(), "CategoryId", "CategoryName", ViewDefinition.CategoryId); } } // pageview which inherits DefinitionFormViewModel <div class=editor-field"> <%= Html.DropDownList("Category",Model.Categories) %> <%= Html.ValidationMessageFor(model => Model.ViewDefinition.Category) %> </div> // controller methods [Authorize] public ActionResult Create() { Definition definition = new Definition(); return View(new DefinitionFormViewModel(definition)); } [AcceptVerbs(HttpVerbs.Post), Authorize] public ActionResult Create(int id,Definition definition) { Term term = termRepository.SingleOrDefault(t => t.TermId == id); if (term == null) { return View("NotFound", new NotFoundModel("Termo não encontrado", "Termo não encontrado", "Nos desculpe, mas não conseguimos encontrar o termo solicitado.", "Indíce de Termos", "Index", "Term")); } else { if (ModelState.IsValid) { try { definition.TermId = term.TermId; definition.ResponsibleUser = User.Identity.Name; UpdateModel(definition); term.Definitions.Add(definition); termRepository.SaveAll(); return RedirectToAction("Details", "Term", new { id = term.TermId }); } catch (System.Data.SqlClient.SqlException sqlEx) { ModelState.AddModelError("DatabaseError", "Houve um erro na inserção desta nova definição"); } catch { foreach (RuleViolation rv in definition.GetRuleViolations()) { ModelState.AddModelError(rv.PropertyName, rv.ErrorMessage); } } } } return View(new DefinitionFormViewModel(definition)); } I'm sorry about the long post, but I cant figure this out. I got no graphic errors or exceptions. My execution terminates in if (ModelState.IsValid). Thanks for your time George

• How do you unit test a class that's meant to talk to data?

  - by Arda Xi

  I have a few repository classes that are meant to talk to different kinds of data, deriving from an IRepository interface laid out like so: In implementations, the code talks to a data source, be this a directory of XML files or a database or even just a cache. Is it possible to reliably unit test any of these implementations? I don't see a mock implementation working, because then I'm only testing the mock code and not the actual code.

• How to change the extension of a processed xml file (using eXist & cocoon)

  - by Carsten C.

  Hi all, I'm really new to this whole web stuff, so please be nice if I missed something important to post. Short: Is there a possibility to change the name of a processed file (eXist-DB) after serialization? Here my case, the following request to my eXist-db: http://localhost:8080/exist/cocoon/db/caos/test.xml and I want after serialization the follwing (xslt is working fine): http://localhost:8080/exist/cocoon/db/caos/test.html I'm using the followong sitemap.xmap with cocoon (hoping this is responsible for it) <map:match pattern="db/caos/**"> <!-- if we have an xpath query --> <map:match pattern="xpath" type="request-parameter"> <map:generate src="xmldb:exist:///db/caos/{../1}/#{1}"/> <map:act type="request"> <map:parameter name="parameters" value="true"/> <map:parameter name="default.howmany" value="1000"/> <map:parameter name="default.start" value="1"/> <map:transform type="filter"> <map:parameter name="element-name" value="result"/> <map:parameter name="count" value="{howmany}"/> <map:parameter name="blocknr" value="{start}"/> </map:transform> <map:transform src=".snip./webapp/stylesheets/db2html.xsl"> <map:parameter name="block" value="{start}"/> <map:parameter name="collection" value="{../../1}"/> </map:transform> </map:act> <map:serialize type="html" encoding="UTF-8"/> </map:match> <!-- if the whole file will be displayed --> <map:generate src="xmldb:exist:/db/caos/{1}"/> <map:transform src="..snip../stylesheets/caos2soac.xsl"> <map:parameter name="collection" value="{1}"/> </map:transform> <map:transform type="encodeURL"/> <map:serialize type="html" encoding="UTF-8"/> </map:match> So my Question is: How do I change the extension of the test.xml to test.html after processing the xml file? Background: I'm generating some information out of some xml-dbs, this infos will be displayed in html (which is working), but i want to change some entrys later, after I generated the html site. To make this confortable, I want to use Jquery & Jeditable, but the code does not work on the xml files. Saving the generated html is not an option. tia for any suggestions [and|or] help CC Edit: After reading all over: could it be, that the extension is irrelevant and that this is only a problem of port 8080? I'm confused...

• Resharper Warnings with MVVM

  - by Dan Bryant

  As I implement the MVVM pattern with WPF, I'm finding that Resharper is often warning me that certain properties are never used in my ViewModels. The problem is that they are being used, but only by the data binding system. Has anyone else encountered this annoyance and is there a way to help Resharper realize that these properties are, indeed, being used? I am glad, at least, that VS 2010 properly realizes that [Import] tagged members won't "always be null", but hopefully I can fix this issue as well.

• ASP.NET Exception Handling in background threads

  - by Xodarap

  When I do ThreadPool.QueueUserWorkItem, I don't want unhandled exceptions to kill my entire process. So I do something like: ThreadPool.QueueUserWorkItem(delegate() { try { FunctionIActuallyWantToCall(); } catch { HandleException(); } }); Is this the recommended pattern? It seems like there should be a simpler way to do this. It's in an asp.net-mvc app, if that's relevant.

• Datamapper In Memory Database

  - by Daniel Ribeiro

  It is easy to setup Datamapper with a Sqlite3 in memory database with: DataMapper.setup :default, 'sqlite3::memory:'. However, when testing, I'd like to destroy the whole in memory database after each test, instead of invoking automigrate! as a shortcut on dropping everything. Is it possible? Or is it enough to set the default repository to nil, and let the garbage collector dispose of it?
