• save state of external running program

  - by SuitUp

  Hi, my goal is to save state of running process and later start from this point. This is not necessary need to be state from this exact moment, let's say save after 5 seconds is good too. Problem is, i can't alter in code of this external program, i am even don't aware of it's architecture. I have resources to save whole program to disk from memory, but i need some tips, where to start. I can't use any VM like Virtual Box to save state of whole operating system, and program can be written in c++ or c or c#...

• JSF (and friends) tags vs. traditional html tags

  - by H3wh0s33ks

  So this question came up today and I didn't have a specific or scientific answer. What are the costs associated with using jsf (or tomahawk, faclets, etc., etc.) tags in place of traditional html tags. My gut reaction is that you should use jsf tags in situations where you need the additional functionality they provide, and use traditional tags when you don't. Also I feel like jsf tags would require more resources (since the server has to take them and rerender them as html anyways) than html. Does anybody know what the cost actually is (as far as time and memory)? Also useful information is what is the convention that is in use, pure jsf or a mixture of the two?

• Ruby on Rails ActiveScaffold: Showing {{model}} instead of model name?

  - by AnExtremelySmellyPerson

  Hi there, I'm using ActiveScaffold with Ruby on Rails and I'm loving it, however there is one weird thing. Whenever I hit "Edit" or "Create New" in my webapp's ActiveScaffold, it says "Create {{model}}" or "Update {{model}}" in the webapp rather than using the model's name. Why is this? I have an ads_controller.rb that includes this: active_scaffold :ad do |config| config.label = "Ads" config.columns = [:name, :description, :imageUrl, :linkUrl, :apps, :created_at, :updated_at] config.update.columns = [:name, :description, :imageUrl, :linkUrl, :apps] config.create.columns = config.update.columns list.sorting = {:created_at => 'DESC'} columns[:imageUrl].label = "Image URL" columns[:linkUrl].label = "Link URL" end And my routes.rb includes this: map.namespace :admin do |admin| admin.root :controller => 'admin_home', :action => 'index' admin.resources :ads, :active_scaffold => true end Any thoughts on why I'm seeing "Create {{model}}" instead of "Create ad" ?

• Clojure for a lisp illiterate

  - by dbyrne

  I am a lifelong object-oriented programmer. My job is primarily java development, but I have experience in a number of languages. Ruby gave me my first real taste of functional programming. I loved the features Ruby borrowed from the functional paradigm such as closures and continuations. Eventually, I graduated to Scala. This has been a great way to gradually learn to approach non-trivial problems in a functional manner. Now I am interested in Clojure. I know all the sexy features that make it enticing (software transactional memory, macros, etc.), but I just can't get used to "thinking in lisp". I've seen Rich Hickey's screencasts aimed at java programmers, but they are geared towards explaining language features and not approaching real world problems. I am looking for any advice or resources which have made this transition easier for others.

• How can I improve my programming skills with out a computer (or reading material)?

  - by Tom Duckering

  Given the recent and continued chaos with grounded flights and folks stuck in airports, and what not, I'm wondering if anyone has any suggestions for activities that would help sharpen and develop a progammer's mind. The constraints are: Laptop is out of battery and there are no free sockets. You're bored of the book you're reading or you have none with you. Reasonable resources such as a pen and pad of paper are available. Rules can be bent within reason. As daft examples, things I have thought about are: How I might optimise the boarding of a plane. How I might improve the UI of a departure board.

• Javascript Phone Swap

  - by Batfan

  I've been trying to find a way to do this but, have not found many resources that specifically relate to this situation. I need a javascript (can make use of Jquery if need be) to swap phone numbers on a site. 2 numbers would be specified. One would show on the site by default. The script needs to be able to create a cookie and do this by recognizing a value in the URL string. For Example: http://www.site.com/index.html?value= '?value=' would be the value. This URL (with the additional variable) would bring the user to the same site but, the variable in the string would set the cookie and display a different number. The default number would not be displayed again until the cookies were removed. Due to the situation with my server, I cannot make use of PHP ( I know, that would make things alot easier :P ) Any help would be greatly appreciated.

• Can't find .js file in my mainBundle?!

  - by Nic Hubbard

  This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it. I am using: NSData *jsData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"]]; if (jsData) { NSLog(@"%@", jsData); } else { NSLog(@"Can't find file"); return; } Even checking the [[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"] string returns null. My globaly.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

• Tutorials for an experienced C# user to learn C++

  - by Tim R.

  Are there any good resources for learning C++ that a C# user could use, which don't require knowledge of C? I have quite a good knowledge of C# via courses in my University's game development program (in a 300 level course right now) but now I need to use C++ for a project. I would use a beginner tutorial but they are so hard for me to follow and learn the basic syntax because they start so slowly. I found a few of tutorials for switching from C++ to C#, but none in the other direction. I do have a little bit of Objective C practice from iPhone programming as well.

• Rails routes looking for show action

  - by user1334345

  I am pretty new to rails and basically I want to make a user registration form. I am currently using rails 3.2.3 Basically I want to make basic routes like user/register on top of basic REST route for user. Here are my routes.rb resources :user do collection do get 'register' end end And here are my rake routes: register_user_index GET /user/register(.:format) user#register user_index GET /user(.:format) user#index POST /user(.:format) user#create new_user GET /user/new(.:format) user#new edit_user GET /user/:id/edit(.:format) user#edit user GET /user/:id(.:format) user#show PUT /user/:id(.:format) user#update DELETE /user/:id(.:format) user#destroy From my understanding, since register user is on top of show, it should match with register first before going to show. However, when I try to do localhost:3000/user/register, it gives me this error: No route matches {:action="show", :controller="user"} Can somebody help me with this? Thanks!!

• Port a Rails App from Windows to Mac or Linux

  - by Ryan Max

  Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Either that or install unix on another box. Is there any way I can port my app to this mac or linux machine, without having to start over? I can't find any resources on the internets about this.

• Visual Studio keeps inserting absurd default property value in designer file

  - by Bugz R us

  i have a simple usercontrol with following properties: public partial class RichTextEditorControl : UserControl { public string EditorText { get { return richTextBox1.Rtf; } set { richTextBox1.Rtf = value; } } public string EditorPlainText { get { return richTextBox1.Text; } set { richTextBox1.Text = value; } } } Now whenever I EDIT a form which contains this control, VS fills its designer file with the following code line, and then throws a designer error : this.richTextEditorControl1.EditorPlainText = global::Project.Resources.MyResources_de_DE.SomeString; Now I don't know where it gets this value from ??? I've searched entire solution, and nowhere there's mention of this var, except for 1 file, where it's needed ... Moreover, the code VS writes, has an error in it ?! It doesn't compile ... The only thing I can do is edit the designer file, but the next time I have to edit the form with the designer, the same error happens again ... Where on earth is VS getting this value from ??

• advanced search with mysql

  - by Arsenal

  I'm creating a search function for my website where the user can put in anything he likes in a textfield. It get's matched against anything (name, title, job, car brand, ... you name it) I initially wrote the query with an INNER JOIN on every table that needed to be searched. SELECT column1, column2, ... FROM person INNER JOIN person_car ON ... INNER JOIN car ... This ended up in a query with 6 or 8 INNER JOINs, and a whole lot WHERE ... LIKE '%searchvalue%' Now this query seems to cause a time'out in MySql, and I even got a warning from my hosting provider that the queries just taking up too many resources. Now obviously I'm doing this very wrong, but I was wondering how the correct approach to these kind of search functions is. Thanks!

• Passing Func<T> to controller constructure when using Unity IoC with MVC, advantages?

  - by user1361315

  I was looking at a sample of how to setup Unity IoC with MVC, and noticed someone who recommended the approach of having the parameters of Func. I believe the advantage is this is kind of like lazy loading the service, if it never gets called it will never get executed and not consume any resources. private readonly Func<IUserService> _userService; public CourseController(Func<IUserService> userService) { this._userService = userService; } Versus a parameter without a Func: private readonly IUserService _userService; public CourseController(IUserService userService) { this._userService = userService; } Can someone explain to me the differences, is it really more effecient?

• Backbone JS central model where all views can use

  - by chchrist

  I am new to backbone js and require js. I use requirejS to organize my backbone code into modules. I don't know if this has any importance to what I want though. I want to have a central model where all my views will have access to. They should be able to get and set values. I don't want to use it as each view model though. I need to keep in memory search options, user status (logged in/out) etc. Any ideas? EDIT Maybe the answer is here? Share resources across different amd modules

• Is there a slick way to deploy my silverlight app and change settings programmatically?

  - by MIke S.

  I am fairly new to web development. I am at the point of deployment (for testing). I have a few places (maybe 4 places) where I had to add a URI that was non-relative into the appliation. So now, at deployment, those need to be changed. Is there a slick way of handling this? By slick I mean not manually going through the app and changing the URIs or a blanket find and replace (too risky). I only have 4 places to change now, but this could easily change and cause deployment issues. I am using a Microsoft technology stack. Silverlight, ASP.NET, RIA, etc. Development is done in Visual Studio 2010. I noticed that the web projects have a nifty transformation for the web.config...which is nice. Is there an equivalent mechanism for silverlight resources? Any other ways? Any thoughts?

• Customize iphone app for different clients

  - by gnibbler

  I have an existing app that needs to be compiled for different clients Each client requires their own icon and splash screen. I would also like to be able to conditionally include various features depending whether the particular client requires them or not. I have tried setting up different targets for each client, but not having much luck so far. The different resources with the same name, but a different path keep getting mixed up. Ideally I would like to be able to build an app by duplicating another client that is similar and then just make the minimum number of changes to create the app for the new client. What is the best way to set this app up?

• What algorithm would you use to code a parrot?

  - by Phil H

  A parrot learns the most commonly uttered words and phrases in its vicinity so it can repeat them at inappropriate moments. So how would you create a software version? Assuming it has access to a microphone and can record sound at will, how would you code it without requiring infinite resources? The best I can imagine is to divide the stream using silences in the sound, and then use some pattern recognition to encode each one as a list of tokens, storing new ones as you meet them. Hashing the token sequences and counting occurrences in a database, you could build up a picture of the most frequently uttered phrases. But given the huge variety in phrases, how do you prevent this just becoming a huge list? And the sheer number of pairs to match would surely generate lot of false positives from the combinatorial nature of matching. Would you use a neural net, since that's how a real parrot manages it? Or is there another, cleverer way of matching large-scale patterns in analogue data?

• Can I run multiple websites under a single membership database?

  - by higgsy

  Hi all, I'm trying to plan a series of websites that all share many of the resources such as css/jscript/images/content etc. For this reason I wanted to run all of the websites under the same application and IIS profile, but depending on the URL being used change the masterpage and theme/skin. The ASP.NET membership database seems as if it was designed with this goal in mind because it allows you to setup multiple applications, however I believe the purpose for which this was built was to allow applications to be run under virtual directories/fodlers, not on seperate urls. Is it possible to map a url to a particular application? Thanks in advance Al

• Printing python tkinter output

  - by Eric

  I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

• How to optimize indexing of large number of DB records using Zend_Lucene and Zend_Paginator

  - by jdichev

  So I have this cron script that is deployed and ran using Cron on a host and indexes all the records in a database table - the index is later used both for the front end of the site and the backed operations as well. After the operation, the index is about 3-4 MB. The problem is it takes a lot of resources (CPU: 30+ and a good chunk of memory) and slows the machine down. My question is about how to optimize the operation described below: First there is a select query built using the Zend Framework API, this query is then passed to a Paginator factory that returns a paginator which I am using to balance the current number of items being indexed and not iterate over too much items. The script is iterating over the current items in the paginator object using a foreach loop until reaching the end and then it starts from the beginning after getting items for the next page. I am suspecting this overhead is caused by the Zend_Lucene but no idea how this could be improved.
