• IRb: how to start an interactive ruby session with pre-loaded classes

  - by Shyam

  Hi, As I am going through my journey by adopting the Ruby language, I spend a lot of time inside IRb. It's just fantastic! But, as I am not very aware of it's capabilities, and still a nuby with Ruby, I would like to know the following: How can I 'flush' the session, without restarting IRb (or is this not possible). How can I configure IRb to load a bunch of source files "hello.rb" and "hello_objects.rb", i.e. at startup? I am heavily working in these and it would be nice to know a short hand to load these classes, without manually typing 'load' for each again. Thank you for your answers, comments and feedback!

• PHP Interview questions

  - by David

  Hi, does anyone have any thoughts on what would be considered good technicaly interviews for new php programmers. Im not meaning the little questions that are intended to know language specific intricacies but more on larger interview questions that potential employees may take an hour or 2 to solve in their own time and then come back with. Specifically im looking at PHP and object orientated but are there any ideas on suitable problems that a php programmer should be able to solve within a couple of hours? I am thinking that I want to have demonstrated object orientated techniques and also unit testing capabilities but as for that it can be anything.

• Windows Azure Platform, latest version?

  - by Vimvq1987

  I searched through internet but found nothing. The whitepapers of Windows Azure Platform say something like that: In its first release, the maximum size of a single database in SQL Azure Database is 10 gigabytes A few things are omitted in the technology’s first release, however, such as the SQL Common Language Runtime (CLR) and support for spatial data. (Microsoft says that both will be available in a future version.) I want to know that Microsoft had updated Windows Azure Platform and removed these limits or not? I decided to post this question here instead of Serverfault.com because it's more relative to programming than administration. Thank you

• Java book for programmer with intermediate experience

  - by Anthony Forloney

  I am well aware of this previous question here and have heard great things about those books. I actually bought two of them, Effective Java and Java in a Nutshell as an early Christmas present. I am looking for a good Java book, or books, to further continue my understanding of Java from a recent college graduate point of view. I have learned Java in college and would consider it to be the language I am most comfortable with. Can anyone recommend a good "intermediate" Java book for a situation like mine? This question should be community, I just don't know how to migrate it. I apologize for any inconvenience. Thank you in advance.

• How "healthy" is the haskell community

  - by Asher

  I came across a post where someone wrote something inaccurate about haskell (won't go into it) and he got flammed for it. Which (pleasantly) surprised me. About 3 years ago I read this joke about haskell: All the haskell programmers in the world can fit into a 747 and if that plane were to crash no one would care... or something along those lines. Which brings me to my question: is haskell "mainstream"? Is it mainly used by hobbiest and academics or someone making some serious money from it (which is the true yardstick of how good a language is - just kidding, geez!)?

• Large Scale VHDL modularization techniques

  - by oxinabox.ucc.asn.au

  I'm thinking about implimenting a 16 bit CPU in VHDL. A simplish CPU. ADD, MULS, NEG, BitShift, JUMP, Relitive Jump, BREQ, Relitive BREQ, i don't know somethign along these lines Probably all only working with 16bit operands. I might even cut it down and use only a single operand and a accumulator. With Some status regitsters, Carry, Zero, Neg (unless i use a Accumlator), I know how to design all the parts from logic gates, and plan to build them up from first priciples, So for my ALU I'll need to 'build' a ADDer, proably a Carry Look ahead, group adder, this adder it self is make up oa a couple of parts, wich are themselves made up of a couple of parts. Anyway, my problem is not the CPU design, or the VHDL (i know the language, more or less). It's how i should keep things organised. How should I use packages, How should I name my processes and port maps? (i've never seen the benifit of naming the port maps, or processes)

• Best practices for TDD BDD with code that uses external services / api

  - by adam

  I'm using a twitter gem which basically accesses twitter and lets me grab tweets, timeline etc. Its really good but I have a lot of my code that uses the stuff it returns and I need to test it. The things the gem returns aren't exactly simple strings, there pretty complex objects (scary as well) so im left scratching my head. So basically I'm looking for an answer, book, blog, open-source project that can show me the rights and wrongs of testing around external services. answers that are either not language centric or ruby/rails centric would most greatly be appreciated.

• How to handle value types when embedding IronPython in C#?

  - by kloffy

  There is a well known issue when it comes to using .NET value types in IronPython. This has recently caused me a headache when trying to use Python as an embedded scripting language in C#. The problem can be summed up as follows: Given a C# struct such as: struct Vector { public float x; public float y; } And a C# class such as: class Object { public Vector position; } The following will happen in IronPython: obj = Object() print obj.position.x # prints ‘0’ obj.position.x = 1 print obj.position.x # still prints ‘0’ As the article states, this means that value types are mostly immutable. However, this is a problem as I was planning on using a vector library that is implemented as seen above. Are there any workarounds for working with existing libraries that rely on value types? Modifying the library would be the very last resort, but I'd rather avoid that.

• Can I use XText for a DSL involving an XML file type?

  - by Chris

  I have defined a small DSL that is mostly written in the form of different types of XML files in conjuction with some property files. This works very well but I wish to create an Eclipse Editor to make editing these files easier for beginners (I already have a working parser). The main XML file can reference some items from the .properties files and vice-versa. THe main xml file can also reference other XML files. Certain options should only be available in the main xml file based on the contents of the .properties files and based on some osgi plugins that can be added to the DSL project (the syntax is dynamic depending on context). The structure of the language is fixed but the options available in each attribute or the choice of attributes themselves changes depending on metadata contained in plugin .jar files. Questions: Does XText support dynamic syntax (validation changes depending on external factors)? Does XText support XML files / .properties files? Thank you very much for your help in advance.

• Visualizing an AST created with ANTLR (in a .Net environment)

  - by Benjamin Podszun

  Hi there. For a pet project I started to fiddle with ANTLR. After following some tutorials I'm now trying to create the grammar for my very own language and to generate an AST. For now I'm messing around in ANTLRWorks mostly, but now that I have validated that the parse tree seems to be fine I'd like to (iteratively, because I'm still learning and still need to make some decisions regarding the final structure of the tree) create the AST. It seems that antlrworks won't visualize it (or at least not using the "Interpreter" feature, Debug's not working on any of my machines). Bottom line: Is the only way to visualize the AST the manual way, traversing/showing it or printing the tree in string representation to a console? What I'm looking for is a simple way to go from input, grammar - visual AST representation a la the "Interpreter" feature of ANTLRWorks. Any ideas?

• Wanting a simple overview on how to connect to a SQLite database in Cocoa/Objective-C

  - by Jesse

  Hi, everyone. I've been experimenting with Cocoa and Objective-C programming on the Mac for a few months now, and I am wanting to start developing applications that manage large amounts of data. The trouble is, I'm not really sure where to start with databases. I have a good background in Java programming with SQLite. I've read a bit about CoreData and I haven't been able to find any good resources for just manually connecting to the database. I'm looking for recommendations. Should I try CoreData, and if so, can anyone recommend a good tutorial for someone new to the language? Or, should I try to manually connect and query an SQLite database somehow, and, if so, any tutorials? Any help would be greatly appreciated! Thanks!

• Creating a multiplayer card game

  - by Vikram.exe

  Hi, I was trying to make a multiplayer card game. I know networking concepts, so I know how to handle data between successive turns. I Haven't done a similar thing before so if any one could point me to a tutorial, that would be nice. I am comfortable with html/php/javascript and a bit of adobe flash. Please suggest are these sufficient to create a game or should I go for some other language(s)? Which are the best languages that are currently used to create such multiplayer games? Thanks, Vikram

• 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?

• Shared Source CLI 4.0?

  - by Paul Alexander

  Microsoft released the Shared Source Common Language Infrastructure (the code previously known as ROTOR) code some years ago basically as a reference implementation of the .NET runtime. While the actual .NET runtime (mscorlib, mscoree, mscorjit, etc.) aren't compiled from the code, debugging them shows that they are remarkably similar and at a minimum share much of the same memory structures. This has been an invaluable resource when debugging tricky system behavior with .NET 2.0 compiled assemblies. Now that 4.0 has been released with major changes to the runtime I'd love to find the reference source for that as well. Microsoft has changed names for the source in the past so I'm either searching for the wrong thing, or it hasn't been released. Is there reference source for a .NET 4.0 compatible runtime?

• Use Javascript to copy Text from Label

  - by Josh

  Hello All- Label1 (asp.net control) is located inside Panel1 of my webpage and I have a button called bt. What is the Javascript to copy the Text from Label1 to the clipboard? Thanks, @ artlung, I placed the below code just outside of my form but inside the body. The last line of code I placed inside Panel1 of my form. Anything wrong with this code because nothing happens when I click the Copy to Clipboard button. <script language="JavaScript"> var clip = new ZeroClipboard.Client(); clip.addEventListener( 'mouseDown', function(client) { // set text to copy here clip.setText( document.getElementById('form1.Label1').value ); // alert("mouse down"); } ); clip.glue( 'd_clip_button' ); </script> The next line of code is above the script tags but inside Panel1 in my form <div id="d_clip_button">Copy To Clipboard</div>

• Windows Forms: Enable/Disable WS_CLIPCHILDREN

  - by Agnel Kurian

  How do I turn on/off the WS_CLIPCHILDREN window style in a Windows Forms parent control? I would like to display some text on top of the child control after it has painted. In my parent control, this is what I have: class Parent : public Control { void Parent::OnPaint(PaintEventArgs ^e){ Control::OnPaint(e); // parent draws here // some drawing should happen over the child windows // in other words, do not clip child window regions } }; On checking with Spy++ I find that the parent has the WS_CLIPCHILDREN window style enabled by default. What is the Windows Forms way to turn this off? Note: Sample code is in C++/CLI but I have tagged this C# for visibility... language is immaterial here. Feel free to translate the code to C#.

• Multi choice form field in Django

  - by Dingo

  Hi! I'am developing application on app-engine-path. I would like to make form with multichoice (acceptably languages for user). Code look like this: Language settings: settings.LANGUAGES = ((u"cs", u"Ceština"), (u"en", u"English")) Form model: class UserForm(forms.ModelForm): first_name = forms.CharField(max_length=100) last_name = forms.CharField(max_length=100) languages = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=settings.LANGUAGES) The form is rendered o.k. (all languages have checkbox. IDs, NAMEs is ok.) But if I save some languages for user, those languages don't check checkboxes. User model look like this class User(User): #... languages = db.StringListProperty() #... and view: def edit_profile(request): user = request.user if request.method == 'POST': form = UserForm(request.POST) if form.is_valid(): # ... else: form = UserForm(instance=user) data = {"user":user, "form": form} return render_to_response(request, 'user_profile/user_profile.html', data)

• Web scraping with Python

  - by Jack

  I'm currently trying to scrape a website that has fairly poorly-formatted HTML (often missing closing tags, no use of classes or ids so it's incredibly difficult to go straight to the element you want, etc.). I've been using BeautifulSoup with some success so far but every once and a while (though quite rarely), I run into a page where BeautifulSoup creates the HTML tree a bit differently from (for example) Firefox or Webkit. While this is understandable as the formatting of the HTML leaves this ambiguous, if I were able to get the same parse tree as Firefox or Webkit produces I would be able to parse things much more easily. The problems are usually something like the site opens a <b> tag twice and when BeautifulSoup sees the second <b> tag, it immediately closes the first while Firefox and Webkit nest the <b> tags. Is there a web scraping library for Python (or even any other language (I'm getting desperate)) that can reproduce the parse tree generated by Firefox or WebKit (or at least get closer than BeautifulSoup in cases of ambiguity).

• Hidden Features of ActionScript

  - by Ole Jak

  What are some of the hidden features of ActionScript? ActionScript is widely used language. It has been around for so many years. So at least from the existing features, do you know any that are not well known but very useful. Of course, this question is along the lines of: Hidden Features of JavaScript Hidden Features of CSS Hidden Features of C# Hidden Features of VB.NET Hidden Features of Java Hidden Features of ASP.NET Hidden Features of Python Hidden Features of TextPad Hidden Features of Eclipse Hidden Features of HTML Do not mention features of ActionScript 2.0, since it is quite old and not eweryone can understend it now Please specify one feature per answer. Note that it's not always a great idea to use these hidden features; often times they are surprising and confusing to others reading your code.

• Mixin or Trait implementation in AS3?

  - by Brian Heylin

  I'm looking for ideas on how to implement a Mixin/Trait style system in AS3. I want to be able to compose a number of classes together into a single object. Of course this is not a language level feature of AS3, but I'm hoping that there is maybe some way to do this using prototype based techniques or maybe some bytecode hacking that I believe AsMock uses to implement it's functionality. An existing Java example is Qi4J where the user define interfaces that the Qi4j framework implements based on metadata tags and coding by convention. Has anyone any ideas on how to get the Mixin/Trait concept working within AS3?

• Switching from web to desktop development

  - by Dziamid

  Being a web developer (php, symfony, doctrine) for 2 years now, I was recently asked by a friend to come up with a desktop solution. So I developed a project, installed a LAMP on his machine and he is mostly happy using it now. But I'm not. It just doesn't seem right to wait for a server response from a localhost. Obviously php isn't suited for desktop development. So, my question is: what language \ framework would you advice a php programmer if he was going to develop a desktop application (something that you can install, that has it's own gui, but utilizes the similar concepts of web apps: css, javascript, orm). I would like to bring up Python as a possible answer to my question. Does anyone have an experience of developing a desktop app with Python, utilizing an ORM and(or) HTML-based GUI?

• Extract string from string using Regex

  - by stacker

  I want to extract MasterPage value directive from a view page. I want the fastest way to do that, taking into account a very big aspx pages, and a very small ones. I think the best way is to do that with two stages: Extract the page directive section from the view (using Regex): <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> Then, extract the value inside MasterPageFile attribute. The result needs to be: ~/Views/Shared/Site.Master. Can I have help from someone to implement this? I badly want to use only regex, but I don't Regex expert. Another thing, Do you think that Regex is the fastest way to do this?
