  • How to make CSS/HTML prototyping faster for engineers without strong CSS skills?

    - by rdeshpande
    I've been developing Ruby on Rails applications for some time, and have often found help to develop generate the templates of HTML with accompanying CSS. However, I'd like to make an attempt at doing this myself. Initial experiments leave me feeling like my process is really slow. I'm writing all my Rails code in VIM, which, with accompanying aliases to run the test suite, is pretty fast for me. However, the back-and-forth between browser/VIM to see new changes seems cumbersome - I'm guessing finding an editor with an embedded browser that constantly sees new changes is ideal for this (any suggestions?) So far I've experimented with Blueprint, which at the onset seems like it will save me a ton of time. However, what other tools have helped you do the PSD-HTML/CSS conversion as fast as you can?

  • Good File Organization Suggestions for Developer

    - by Paul
    I am struggling a little with folder organization to organize the many projects that I work on. I work on OS X - right now I am using ~/Development/ as the root folder, and I have many types of projects. For example, I have my iPhone apps under ~/Development/Xcode I develop in many languages, from PHP, to Ruby, to Python, to Objective-C. So, for example, I might have a couple of open-source apps based on PHP where I am using the Zend framework. Some of these projects are for clients, others are tests/experiments when learning a new language or general experimenting. I am really interested in how other developers have organized code/projects and could pass along some advice to make it very easy to navigate through code/projects related to many languages and types of projects.

  • How are python pages coded and what can the language be compared to? [closed]

    - by avon_verma
    I have a few questions about python I've seen many pages like these on Google http://mail.google.com/support/bin/answer.py?answer=6583 https://www.google.com/adsense/support/bin/topic.py?topic=13488 ...that have .py extensions. 1: Are pages like these built on pure python code, but printing out html like print "<div etc..." or like the typical asp,jsp,php type of pages with html pages and embedded python code like: <html> <% some python code %> </html> 2: What is python mainly used for making? windows apps or web or .. ? 3: Are ruby and perl also similar to python?

  • Developing and deploying games for Windows, Mac (& Linux)

    - by nornagon
    I want to write games that run on all the major platforms. I also want people to be able to play them by downloading a file and double clicking it. That means a single .exe/.app file. I'm happy to use OpenGL directly for graphics. What I don't know how to do is show a window, handle mouse/keyboard input and play sounds in a cross-platform manner. I don't really mind what the underlying language is, as long as it isn't C++ or Java. C#, Ruby or Python would be preferable, in that order :) Please, SO, save me from having to write Flash games!

  • How to write custom SQLite functions in Javascript inside a Webkit browser?

    - by Jay Godse
    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

  • How I Can do web programming with Lisp or Scheme?

    - by Castro
    I usually write web apps in PHP, Ruby or Perl. I am starting the study of Scheme and I want to try some web project with this language. But I can't find what is the best environment for this. I am looking for the following features: A simple way of get the request parameters (something like: get-get #key, get-post #key, get-cookie #key). Mysql access. HTML Form generators, processing, validators, etc. Helpers for filter user input data (something like htmlentities, escape variables for put in queries, etc). FLOSS. And GNU/Linux friendly. So, thanks in advance to all replies.

  • Ideal timeout period for dns lookup

    - by railscoder
    In my rails app i do a nslookup using a ruby library resolv. If the site like dgdfgdfgdfg.com is entered its talking too long to resolve. in some instance like 20 sec.(mostly for non-existent sites) Because it cause the application to slowdown. So i though of introducing a timeout period for the dns lookup. What will be the ideal timeout period for the dns lookup so that resolution of actual site doesnt fail. will something like 10 sec will be fine?

  • Create an seo and web accessibility analyzer

    - by rebellion
    I'm thinking of making a little web tool for analyzing the search engine optimization and web accessiblity of a whole website. First of all, this is just a private tool for now. Crawling a whole website takes up alot of resources and time. I've found out that wget is the best option for downloading the markup for a whole site. I plan on using PHP/MySQL (maybe even CodeIgniter), but I'm not quite sure if that's the right way to do it. There's always someone who recommends Python, Ruby or Perl. I only know PHP and a little bit Rails. I've also found a great HTML DOM parser class in PHP on SourceForge. But, the thing is, I need some feedback on what I should and should not do. Everything from how I should make the crawl process to what I should be checking for in regards to SEO and WCAG. So, what comes to your mind when you hear this?

  • Is there a better way to minimize this C# event repetition?

    - by Damien Wildfire
    I have a lot of code like this: public class Microwave { private EventHandler<EventArgs> _doorClosed; public event EventHandler<EventArgs> DoorClosed { add { lock (this) _doorClosed += value; } remove { lock (this) _doorClosed -= value; } } private EventHandler<EventArgs> _lightbulbOn; public event EventHandler<EventArgs> LightbulbOn { add { lock (this) _lightbulbOn += value; } remove { lock (this) _lightbulbOn -= value; } } // ... } You can see that much of this is boilerplate. In Ruby I'd be able to do something like this: class Microwave has_events :door_closed, :lightbulb_on, ... end Is there a similar shorter way of removing this boilerplate in C#?

  • Getting started with C++ ( the paradigm shift from Python )

    - by orokusaki
    I want to learn C++ so that i can develop C++ Python modules for server-related stuff. I'm a purely dynamic languages developer (Python, PHP, Ruby, etc). I want to learn a fast language, and if I'm going to do this, I'd rather learn a really fast language like C++. Before I even get started though, I understand that suddenly working with static types, a different syntax, and compiling code will be quite the paradigm shift. Is there any advice that a C++ dev who also has dynamic languages experience can give me to me to help me make that shift faster?

  • Are tags considered requirements? [closed]

    - by krunk
    I'm new to stack overflow, made a few responses. I responded to a question that was something like: "I need to do X, I found a sed one liner that almost does it, but not quite" And was tagged 'sed'. I assumed the user just wanted a solution and tagged it with sed because it was a possible answer. So I suggested an alternate way using another tool that was more concise and didn't involve regex (another one-liner). I received a down vote for not meeting the requirement of the user. Since I'd like to make sure I conform to good forum etiquette, my question is: Are tags considered hard requirements that should limit the scope of responses? (within reason of course, a .NET question with a .NET tag obviously shouldn't receive a ruby answer).

  • Stuck in implementing Pagination in Android

    - by user443141
    I am implementing pagination for ListView in Android . I am extending the BaseAdapater class for customising the ListView. Already I have the code working fine for the Customised ListView. Below is the new requirement. 1I am fetching 6 items from server & displaying them . Now when the user scrolls to the 6th item(end of list) , I need to call the server to fetch the next 6 items & update the Listview I have overriden the methods ipublic void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, int totalItemCount) iipublic void onScrollStateChanged(AbsListView view, int scrollState) In the first response from the server, I get the total no of pages from the server & for each time I call the server , I get the current page value . Kindly provide me the steps/sample code on how to check the last item of the list & update the list . The code should be iterative since I may need to call multiple times & fetch from server. Warm Regards, CB

  • XMLHttpRequest progressive download?

    - by StackedCrooked
    Just for fun I was creating a JavaScript console for controlling my PC. It involves a small webserver that takes command strings and forwards those to the system using popen calls (to be more specific popen4 on a Ruby mongrel server). The stdout channels are redirected to the http response. The problem is that the response only arrives once the entire contents of stdout has been sent. This is ok for small commands, but not for a command like find / which lists all the files in the system. In such situations it would be nice to have the results shown progressively in the webview (just like in the regular terminal). I thought that using XMLHttpRequest synchronously might result in progressive downloading, but it doesn't seem so. Is there any way to make it work?

  • Handling large (object) datasets with PHP

    - by Aron Rotteveel
    I am currently working on a project that extensively relies on the EAV model. Both entities as their attributes are individually represented by a model, sometimes extending other models (or at least, base models). This has worked quite well so far since most areas of the application only rely on filtered sets of entities, and not the entire dataset. Now, however, I need to parse the entire dataset (IE: all entities and all their attributes) in order to provide a sorting/filtering algorithm based on the attributes. The application currently consists of aproximately 2200 entities, each with aproximately 100 attributes. Every entity is represented by a single model (for example Client_Model_Entity) and has a protected property called $_attributes, which is an array of Attribute objects. Each entity object is about 500KB, which results in an incredible load on the server. With 2000 entities, this means a single task would take 1GB of RAM (and a lot of CPU time) in order to work, which is unacceptable. Are there any patterns or common approaches to iterating over such large datasets? Paging is not really an option, since everything has to be taken into account in order to provide the sorting algorithm.

  • data filter using dataloadoptions

    - by Tassadaque
    Using dataloadoptions i have tried the following example Northwnd db = new Northwnd(@"northwnd.mdf"); // Preload Orders for Customer. // One directive per relationship to be preloaded. DataLoadOptions ds = new DataLoadOptions(); ds.LoadWith<Customer>(c => c.Orders); ds.AssociateWith<Customer> (c => c.Orders.Where(p => p.ShippedDate != DateTime.Today)); db.LoadOptions = ds; var custQuery = from cust in db.Customers where cust.City == "London" select cust; foreach (Customer custObj in custQuery) { Console.WriteLine("Customer ID: {0}", custObj.CustomerID); foreach (Order ord in custObj.Orders) { Console.WriteLine("\tOrder ID: {0}", ord.OrderID); foreach (OrderDetail detail in ord.OrderDetails) { Console.WriteLine("\t\tProduct ID: {0}", detail.ProductID); } } } Now i need to ask how can i display Category ID and Category Name of the productID (i am supposing that One product can be in at most one category) by extending the above example Regards

  • Can layouts be chosen by Grails controllers?

    - by maerics
    I'm building a CMS as a learning exercise in Grails and would like to give content managers the ability to choose between different HTML page structures (e.g. 2 column, 3 column, etc). Grails Layouts seem like a logical choice but is it possible for a Grails controller to explicitly name which layout will be used for rendering? Ideally there would be a layout option to the render method, per Ruby on Rails but I don't see anything like it. It seems like it might be possible using the applyLayout method by passing the name of the layout but this requires each GSP page to explicitly request layout (annoying overhead per-page) rather than using Layout by Convention. Any ideas?

  • Where to add an overloaded operator for the tr1::array?

    - by phlipsy
    Since I need to add an operator& for the std::tr1::array<bool, N> I wrote the following lines template<std::size_t N> std::tr1::array<bool, N> operator& (const std::tr1::array<bool, N>& a, const std::tr1::array<bool, N>& b) { std::tr1::array<bool, N> result; std::transform(a.begin(), a.end(), b.begin(), result.begin(), std::logical_and<bool>()); return result; } Now I don't know in which namespace I've to put this function. I considered the std namespace as a restricted area. Only total specialization and overloaded function templates are allowed to be added by the user. Putting it into the global namespace isn't "allowed" either in order to prevent pollution of the global namespace and clashes with other declarations. And finally putting this function into the namespace of the project doesn't work since the compiler won't find it there. What had I best do? I don't want to write a new array class putted into the project namespace. Because in this case the compiler would find the right namespace via argument dependent name lookup. Or is this the only possible way because writing a new operator for existing classes means extending their interfaces and this isn't allowed either for standard classes?

  • Free service that allows storing game data online?

    - by StackedCrooked
    I have created a small game in Java and I would like to add the ability for a player to publish his highscores online. I'm willing to write the server software myself (it's easy these days with Ruby Mongrel, or even C++). All I just need to have some sort hosting. One solution that immediately comes to mind is Amazon EC2. But that's kind of expensive for my needs. Since the requirements are very minimal (I don't even need a website, just a web service) I think there may be a cheaper solution out there. Does anyone know of a free or cheap provider for this kind of thing?

  • Neo4j+Gremlin : Trouble with T.gte and floating point node attributes

    - by letronje
    For a type of nodes in my graph, attribute values for an attribute(named 'some_count') is either missing or an integer or a float. I'm trying to write gremlin to filter these nodes based on minimum value for this attribute. I first verified that the values are indeed present by firing the following gremlin g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).some_count Next, I tried filtering by exact value and that works and show me the matching nodes or gives an empty array if there is no match g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.eq, 120000.0d) But the following query that uses the 'greater than or equal to' comparator doesn't work. g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.gte, 1.0d) this returns nil (I'm querying via ruby/rails using Neo4j AR Adapter ) Instead of returning an empty array for no match, it returns a nil, which tells me something could be wrong with the query itself. I'm running neo4j community server 1.8. Is there a way I can ask Neo4j to log errors/queries, to see what could be going wrong ?

  • How can I kill MySQL queries every 60 seconds in Windows?

    - by Ethan Allen
    I want to check my MySQL server every minute and kill queries that have run longer than 150 seconds. The main reason I want to do this is because I don't want queries from certain people to lock up the DB for everyone else. I know this is not the ultimate solution to the problem, but at least it's a fallback in case something goes wrong with a query. I don't have a slave DB (this is just an at-home project). I'd like to schedule a script to run that does this for me. I'm unfamiliar with Perl or Ruby and I need it done on my Windows 2008 Server box. I've looked into creating a simple cmd line script, but that doesn't seem to be possible. I know currently I can do something like this but I have to do it manually: mysqladmin processlist mysqladmin kill Anyone have any ideas or examples on how I could do this?

  • Keeping User-Input UITextVIew Content Constrained to Its Own Frame

    - by siglesias
    Trying to create a large textbox of fixed size. This problem is very similar to the 140 character constraint problem, but instead of stopping typing at 140 characters, I want to stop typing when the edge of the textView's frame is reached, instead of extending below into the abyss. Here is what I've got for the delegate method. Seems to always be off by a little bit. Any thoughts? - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { BOOL edgeBump = NO; CGSize constraint = textView.frame.size; CGSize size = [[textView.text stringByAppendingString:text] sizeWithFont:textView.font constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; CGFloat height = size.height; if (height > textView.frame.size.height) { edgeBump = YES; } if([text isEqualToString:@"\b"]){ return YES; } else if(edgeBump){ NSLog(@"EDGEBUMP!"); return NO; } return YES; } EDIT: As per Max's suggestion below, here is the code that works: - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { CGSize constraint = textView.frame.size; NSString *whatWasThereBefore = textView.text; textView.text = [textView.text stringByReplacingCharactersInRange:range withString:text]; if (textView.contentSize.height >= constraint.height) { textView.text = whatWasThereBefore; } return NO; }

  • C# Hook Forms / Windows / Dialogs etc. (via HWND?) to Capture Video Buffer (D3D Device?)

    - by Drax
    I am looking to create a very simple C# application which runs Full-Screen in Direct3D, and is able to grab the Desktop 'scene', mapping each Window from the Desktop to a Textured Polygon in my D3D Scene... I'm hoping to create a simplistic "3D Desktop" type of application as an experiment, and I'm wondering if there is a specific method for doing something like the following: 1)Get a list of all the Windows open on the Desktop (List of HWNDs?). 2)Grab the X,Y position of each Window, as well as the Width and Height. 3)Grab the Rendered image of each Window (magic happens here). 4)Create a new Texture/Surface in D3D using the Width and Height of the Window(s), and apply the Image we grabbed as a Texture. Is there an efficient 'best practice' for acquiring the actual image(s) being rendered to the Desktop? Is there also a 'best practice' for "extending the desktop" to a virtual second, third, etc. "desktop" and being able to swap between them, including creating a unique instance of the task-bar for each virtual desktop. Thanks a million for any suggestions!

  • Application logic for invoicing and subscriptions?

    - by Industrial
    Hi everyone, We're just in the planning stage of a web app that offers subscriptions to our customers. The subscription periods varies and can be prolonged indefinitely by our customers, but are always at least one month (30 days). When a customer signs up, the customer information (billing address, phone number and so on) are stored in a customers table and a subscription is created in the subscriptions table: id | start_date | end_date | customer_id -------------------------------------------------------- 1 | 2010-12-31 | 2011-01-31 | 1 Every month we'll loop through the subscriptions table (cronjob preferably) and create invoices for the past subscription period, which are housed in their own table - invoices. Depending on the customer, invoices are manually printed out and sent by mail, or just emailed to the customer. Due to the nature of our customers and the product, we need to offer a variety of different payment alternatives including wire transfer and card payments, hence some invoices may need to be manually handled and registered as paid by our staff. The 15th every month, the invoices table are looped through and if no payment has been marked for the actual invoice, the according subscription will be removed. If there's a payment registered, the end_date in the subscriptions table is incremented by another 30 days (or what now our period our customer has chosen). Are we looking at headaches by incrementing dates forwards and backwards to handle non-paying customers and extending subscriptions? Would it be a better idea to add new subscriptions as customers extends their subscription?

  • How might you unobtrusively enhance the jQuery Datepicker class?

    - by Teflon Ted
    You can pass special strings into jQuery's Datepicker class setDate() method like "+7" which will be translated into "7 days from today": http://docs.jquery.com/UI/Datepicker#method-setDate But you can't get that "+7" back out. When you call getDate() you get the calculated resulting date. I have a use case where I need to pull out the special string "+7" for propagation. One chunk of code is passing a special string into the Datepicker and passing the Datepicker over to another chunk of code which pulls out the date, but the latter sometimes needs to know the special string rather than the calculated date. So I need to enhance the Datepicker tool to (a) store the special code internally and (b) expose it via a method like getOriginallyPassedInDate() or some such. I'm not a jQuery/Javascript ninja so I could really use some guidance on how I might preferably-unobtrusively add the necessary functionality to the Datepicker class, the way you might monkey-patch an object in Ruby I'm guessing.
