• Rails 2.3.4 Vs Rails 3 + Book - Beginner in RoR

  - by zengr

  Hi, I have started with Ruby and Rails development and I am a Java developer from the last 2 years (student). I am in for two things: Learn Ruby Make my website on ROR I have Agile Web Development with Rails, 2nd Edition. So, here are my questions: How is the Agile Web Development with Rails book to start with, where I don't know anything about Ruby and proficient with Java. What is the difference between 2nd and 3rd edition? People say the changes are irrelevant for a starter, how far is that statement correct? Should I start with Rails 2.3.4 or Rails 3 (around the corner)?

• Merging: hg/git vs. svn

  - by stmax

  I often read that hg (and git and...) are better at merging than svn but I have never seen practical examples of where hg/git can merge something where svn fails (or where svn needs manual intervention). Could you post a few step-by-step lists of branch/modify/commit/...-operations that show where svn would fail while hg/git happily moves on? Practical, not highly exceptional cases please... Some background: we have a few dozen developers working on projects using svn, with each project (or group of similar projects) in its own repo. We know how to apply release- and feature-branches so we don't run into problems very often (i.e. we've been there, but we've learned to overcome joel's problems of "one programmer causing trauma to the whole team" or "needing six developers for two weeks to reintegrate a branch"). We have release-branches that are very stable and only used to apply bugfixes. We have trunks that should be stable enough to be able to create a release within one week. And we have feature-branches that single developers or groups of developers can work on. Yes, they are deleted after reintegration so they don't clutter up the repository. ;) So I'm still trying to find the advantages of hg/git over svn. I'd love to get some hands-on experience, but there aren't any bigger projects we could move to hg/git yet, so I'm stuck with playing with small artifical projects that only contain a few made up files. And I'm looking for a few cases where you can feel the impressive power of hg/git, since so far I have often read about them but failed to find them myself.

• Cython Speed Boost vs. Usability

  - by zubin71

  I just came across Cython, while I was looking out for ways to optimize Python code. I read various posts on stackoverflow, the python wiki and read the article "General Rules for Optimization". Cython is something which grasps my interest the most; instead of writing C-code for yourself, you can choose to have other datatypes in your python code itself. Here is a silly test i tried, #!/usr/bin/python # test.pyx def test(value): for i in xrange(value): i**2 if(i==1000000): print i test(10000001) $ time python test.pyx real 0m16.774s user 0m16.745s sys 0m0.024s $ time cython test.pyx real 0m0.513s user 0m0.196s sys 0m0.052s Now, honestly, i`m dumbfounded. The code which I have used here is pure python code, and all I have changed is the interpreter. In this case, if cython is this good, then why do people still use the traditional Python interpretor? Are there any reliability issues for Cython?

• Java Date vs Calendar

  - by Marty Pitt

  Could someone please advise the current "best practice" around Date and Calendar types. When writing new code, is it best to always favour Calendar over Date, or are there circumstances where Date is the more appropriate datatype?

• best practices - multiple functions vs single function with switch case

  - by Amit

  I have a situation where I need to perform several small (but similar) tasks. I can think of two ways to achieve this. First Approach: function doTask1(); function doTask2(); function doTask3(); function doTask4(); Second Approach: // TASK1, TASK2, ... TASK4 are all constants function doTask(TASK) { switch(TASK) { case TASK1: // do task1 break; case TASK2: // do task2 break; case TASK3: // do task3 break; case TASK4: // do task4 break; } } A few more tasks may be added in future (though the chances are rare. but this cannot be ruled out) Please suggest which of the two approaches (or if any other) is a best practice in such a situation.

• ESRI frameworks: java vs javascript

  - by Luke

  I'm about to develop a web mapping application with ESRI Products like ArcGIS Server and Image Server. I can't find a good comparison between the Java Web ADF and the Javascript Framework. They're of course different because one is a full environment and the other is only client side but it's much more concise and the step to start is minimal. Another problem is that the Java Web ADF is not compatible with our current application server (JBoss 4.2.2) and require an old 4.0.2 version. Someone out there has experience that can help me? Many thanks.

• Telerik vs. Infragistics for Silverlight

  - by JeffN825

  Yes, this is certainly a duplicate question, but I wanted to get some fresh takes. My impression is that Telerik is a much more complete suite, but I'm really really turned off by the responsiveness of their controls. It just seems "clunky" in terms of responsiveness (I have a very fast computer and video card). Scrolling in a grid and transitions chunk, even in their latest demos where they claim to have good performance. I do like that their WPF suite matches their SL one in terms of API. Infragistics has fewer controls and less theming possibilities, but their controls are very responsive. Scrolling in a grid is fluid, as are their combo menus and all the other controls. I checked out ComponentOne and their controls seem analogous to Telerik's in terms of the points mentioned above but are a little less "pretty". Any thoughts from other users of these suites? Basically, what I'm looking for is a suite that will be highly performant and responsive, relatively customizable from a theming standpoint, and have enough functionality to develop a LOB SL application without having to use multiple suites to satisfy the majority of common requirements.

• Serializing WPF RichTextBox to XAML vs RTF

  - by chaiguy

  I have a RichTextBox and need to serialize its content to my database purely for storage purposes. It would appear that I have a choice between serializing as XAML or as RTF, and am wondering if there are any advantages to serializing to XAML over RTF, which I would consider as more "standard". In particular, am I losing any capability by serializing to RTF instead of XAML? I understand XAML supports custom classes inside the FlowDocument, but I'm not currently using any custom classes (though the potential for extensibility might be enough reason to use XAML).

• jQuery RJS inserting string vs dom.

  - by Dmitriy Likhten

  So I am trying to use jQuery to insert data from an ajax call. I actually use the jquery.form plugin, and have the ajax form submitted with a dataType: 'script'. The response is a jquery expression which contains a <%= javascript_escape(render ...) %> erb tag (similar to what the railscasts episode 136 instructs to do). However the end result is that the full text of the render is inserted as if that was the content to be inserted into the page, as text, not as dom elements. Could the fact that the render had some newlines at the beginning be the cause? Dom text: "\n \n &lt;li>....&lt;/li>" I also tried having jQuery just read the response as a script and execute it, and used the prototype-based rjs stuff, same effect, the text is inserted into the dom. Are there any reasons why such a behavior would be experienced? A bit of clarification: My response.js.erb is jQuery("#content").append("<%= escape_javascript(render(:partial => "widgets")) %>"); jQuery("#information").text("Finally, something happened!"); The full text inside the append() call is inserted as text into #content.

• Performance Hosting under WAS vs Host as Service?

  - by ashraf

  I have some performance issue when I host WCF service (net.tcp) under WAS (IIS 7). It is working fine when I host service under console application. The issue is WCF Become Slow After Being Idle For 15 Seconds and a solution. After applying Wenlong Dong workaround delay is gone, but it does not work in WAS (IIS 7). I tried to put "ThreadPoolTimeoutWorkaround.DoWorkaround()" in static AppInitialize() as suggested here, still no luck. Thanks

• App.config vs. .ini files

  - by Jakob Gade

  I'm reviewing a .NET project, and I came across some pretty heavy usage of .ini files for configuration. I would much prefer to use app.config files instead, but before I jump in and make an issue out of this with the devs, I wonder if there are any valid reasons to favor .ini files over app.config?

• Eclipse RCP: Actions vs Commands - would like an update

  - by nEm

  I know this question has been asked before but it was in 2009 and I haven't found anything more recent either on the web. I was wondering if the answer in that still holds or can it be updated? I am just starting work on an RCP and I haven't been able to decide between actions and commands for my menu items. I will be using a lot of the ones provided by Eclipse such as the Edit, File and some of their sub menu items as well. Since it has been nearly two years for the answer provided in the '09 question, I just wanted to make sure there is nothing else that could sway my decision in either direction or maybe if there have been some new developments that I am not aware of.

• When to use CouchDB vs RDBMS

  - by Andrew Whitehouse

  I am looking at CouchDB, which has a number of appealing features over relational databases including: intuitive REST/HTTP interface easy replication data stored as documents, rather than normalised tables I appreciate that this is not a mature product so should be adopted with caution, but am wondering whether it is actually a viable replacement for an RDBMS (in spite of the intro page saying otherwise - http://couchdb.apache.org/docs/intro.html). Under what circumstances would CouchDB be a better choice of database than an RDBMS (e.g. MySQL), e.g. in terms of scalability, design + development time, reliability and maintenance. Are there still cases where an RDBMS is still clearly the right choice? Is this an either-or choice, or is a hybrid solution more likely to emerge as best practice?

• Getting a Method's Return Value in the VS Debugger

  - by Bullines

  Is it possible to get a method's return value in the Visual Studio debugger, even if that value isn't assigned to a local variable? For example, I'm debugging the following code: public string Foo(int valueIn) { if (valueIn > 100) return Proxy.Bar(valueIn); else return "Not enough"; } Since I'm not setting any local variables in Foo, and assuming I'm not setting a break point in whatever's calling Foo, is there a way to see what the return value is if I have a breakpoint inside of Foo (or another way)? I don't have much experience with the Autos or Intermediate windows, so I'm not sure if those are even a valid option or not.

  Hello all, I want to create a simple batch file that would perform some Visual Studio 2008 refactoring tasks on some files. For example, I would like to call the Refactor.ExtractInferface command on a given file. Can I do this from the command line? Is there a better way (I am sure there is) of doing this? Thanks, H.

• Python try...except comma vs 'as' in except

  - by peter

  What is the difference between ',' and 'as' in except statements, eg: try: pass except Exception, exception: pass and: try: pass except Exception as exception: pass Is the second syntax legal in 2.6? It works in CPython 2.6 on Windows but the 2.5 interpreter in cygwin complains that it is invalid. If they are both valid in 2.6 which should I use?

• valueOf() vs. toString() in Javascript

  - by brainjam

  In Javascript every object has a valueOf() and toString() method. I would have thought that the toString() method got invoked whenever a string conversion is called for, but apparently it is trumped by valueOf(). For example, the code var x = {toString: function() {return "foo"; }, valueOf: function() {return 42; }}; window.console.log ("x="+x); window.console.log ("x="+x.toString()); will print x=42 x=foo This strikes me as backwards .. if x were a complex number, for example, I would want valueOf() to give me its magnitude (so that zero would become special), but whenever I wanted to convert to a string I would want something like "a+bi". And I wouldn't want to have to call toString() explicitly in contexts that implied a string. Is this just the way it is?
