  • How to version control config files pragmatically?

    - by erenon
    Suppose we have a config file with sensitive passwords. I'd like to version control the whole project, including the config file as well, but I don't want to share my passwords. That could be good, if this config file: password=secret foo=bar becomes password=* foo=bar and the other users of the vcs could also set up the password on they own. To ignoring the file isn't a good approach, the developers should be aware, if the config file changes. Example: Local version: password=own_secret foo=bar config file in vcs: password=* foo=bar Then suddenly, the config file changes: password=* foo=bar baz=foo And the local version would become for each developer: password=own_secret foo=bar baz=foo This is my solution. How could I achieve this behaviour? How do you store your config files? Is there a way to do that, or should I hack something?

  • jQuery - iGoogle style interface

    - by samhamilton
    Hi all, I'm currently working on developing a customizable website layout using jQuery, so I can drag, drop, add and remove blocks of content... much like the iGoogle interface. I have my blocks dragging and dropping working with 3 columns of content My question is to do with adding and removing blocks If I use hide(), I can simply hide and show the blocks. If I use remove, I would have to append the list of blocks to load in a new block into a column. I'm not sure which is the best approach to take. I'd be grateful for any advice on best practise, i.e. to hide() or remove() and any other advice on building this kind of interface. Thank, Sam.

  • Code First / Database First / Model First : are they just personnal preferences?

    - by Antoine M
    Merely knowing the internal functionality of each approaches, and after reading a lot of posts, I still can't figure out if each one of them is just a matter of personnal preference for the developper or if they deserve different axes of productivity ? Does one of them should be applyed for some specific productivity needs or MS is just beeing kind offering three different flavours ? Should we consider CF as a sort of improvement over DBF or MF and thinking of it as a futur standard on wich spending a peculiar intelectual investment ... ? Is there a link showing a sort of synthetic table with un-passionate pros and cons for each approach, a little bit like for web-forms and MVC. Sorry for those who will find this question redondant. I know it is.

  • How to convert a MSSQL database (including procedures, functions and triggers) to a firebird databas

    - by user193655
    I am considering migrating to Firebird. To have a "quick start" approach I downloaded the trial of a conversion tool (DBConvert) and tried it. I just picked up a random tool, this tool doesn't convert procedures, functions and triggers (I don't think it is a limit of the trial since there is not an explicit reference to sp, sf and triggers in the link above). Anyway by trying that tool I had the message: "The DB cannot be converted succesfully because some FK names are too long." This is because in some tables I have FK whose description is 32 chars. Is this a real firebird limit or it is possible to overcome it somehow (of course renaming the FK is an extreme option because it is extra work)? Anyway how to convert a MS SQL DB fully to FIREBIRD? Is there a valid tool? Did someone succed in a conversion of non trivial databases?

  • Need help with a conditional SELECT statement

    - by Ethan
    I've got a stored procedure with a select statement, like this: `SELECT author_ID, author_name, author_bio FROM Authors WHERE author_ID in (SELECT author_ID from Books) ` This limits results to authors who have book records. This is the Books table: Books book_ID INT author_ID INT book_title NVARCHAR featured_book BIT What I want to do is conditionally select the ID of the featured book by each author as part of the select statement above, and if none of the books for a given author are featured, select the ID of the first (top 1) book by the author from the books table. How do I approach this?

  • Should I use custom exceptions to control the flow of application?

    - by bonefisher
    Is it a good practise to use custom business exceptions (e.g. BusinessRuleViolationException) to control the flow of user-errors/user-incorrect-inputs??? The classic approach: I have a web service, where I have 2 methods, one is the 'checker' (UsernameAlreadyExists()) and the other one is 'creator' (CreateUsername())... So if I want to create a username, I have to do 2 roundtrips to webservice, 1.check, 2.if check is OK, create. What about using UsernameAlreadyExistsException? So I call only the 2. web service method (CrateUsername()), which contains the check and if not successfull, it throws the UsernameAlreadyExistsException. So the end goal is to have only one round trip to web service and the checking can be contained also in other web service methods (so I avoid calling the UsernameAlreadyExists() all the times..). Furthermore I can use this kind of business error handling with other web service calls completely avoiding the checking prior the call.

  • Why is this variables declared as private and also readonly?

    - by Sergio Tapia
    In the following code: public class MovieRepository : IMovieRepository { private readonly IHtmlDownloader _downloader; public MovieRepository(IHtmlDownloader downloader) { _downloader = downloader; } public Movie FindMovieById(string id) { var idUri = ...build URI...; var html = _downloader.DownloadHtml(idUri); return ...parse ID HTML...; } public Movie FindMovieByTitle(string title) { var titleUri = ...build URI...; var html = _downloader.DownloadHtml(titleUri); return ...parse title HTML...; } } I asked for something to review my code, and someone suggested this approach. My question is why is the IHtmlDownloader variable readonly?

  • How to: Save order of tabs when customizing tabs in UITabBarController

    - by Canada Dev
    I am having problems finding any other information than the docs for how to save the tab order for my UITabBarController, so that the user's customization is saved for next app launch. I have searched online, but have been unable to find any blog posts or articles that goes through the proper code for doing this. I realize I have to use the delegate methods for the UITabBarController (didEndCustomizingViewControllers:) but I am not sure how I best approach persistance in terms of saving the state of the order the user wants the tabs in. Can someone post some code, point me in the right direction or perhaps you have a link for something saved? :) Thanks

  • LINQ-to-SQL vs stored procedures?

    - by scottmarlowe
    I took a look at the "Beginner's Guide to LINQ" post here on StackOverflow (http://stackoverflow.com/questions/8050/beginners-guide-to-linq), but had a follow-up question: We're about to ramp up a new project where nearly all of our database op's will be fairly simple data retrievals (there's another segment of the project which already writes the data). Most of our other projects up to this point make use of stored procedures for such things. However, I'd like to leverage LINQ-to-SQL if it makes more sense. So, the question is this: For simple data retrievals, which approach is better, LINQ-to-SQL or stored procs? Any specific pro's or con's? Thanks.

  • Returning values from Swing using invokeAndWait

    - by Joonas Pulakka
    I've been using the following approach to create components and return values from Swing to/from outside the EDT. For instance, the following method could be an extension to JFrame, to create a JPanel and add it to the parent JFrame: public JPanel threadSafeAddPanel() { final JPanel[] jPanel = new JPanel[1]; try { EventQueue.invokeAndWait(new Runnable() { public void run() { jPanel[0] = new JPanel(); add(jPanel[0]); } }); } catch (InterruptedException ex) { } catch (InvocationTargetException ex) { } return jPanel[0]; } The local 1-length array is used to transfer the "result" from inside the Runnable, which is invoked in the EDT. Well, it looks "a bit" hacky, and so my questions: Does this make sense? Is anybody else doing something like this? Is the 1-length array a good way of transferring the result? Is there an easier way to do this?

  • Multiple robots.txt for subdomains in rails

    - by Christopher
    I have a site with multiple subdomains and I want the named subdomains robots.txt to be different from the www one. I tried to use .htaccess, but the FastCGI doesn't look at it. So, I was trying to set up routes, but it doesn't seem that you can't do a direct rewrite since every routes needs a controller: map.connect '/robots.txt', :controller => ?, :path => '/robots.www.txt', :conditions => { :subdomain => 'www' } map.connect '/robots.txt', :controller => ?, :path => '/robots.club.txt' What would be the best way to approach this problem? (I am using the request_routing plugin for subdomains)

  • Algorithm to match natural text in mail

    - by snøreven
    I need to separate natural, coherent text/sentences in emails from lists, signatures, greetings and so on before further processing. example: Hi tom, last monday we did bla bla, lore Lorem ipsum dolor sit amet, consectetur adipisici elit, sed eiusmod tempor incidunt ut labore et dolore magna aliqua. list item 2 list item 3 list item 3 Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquid x ea commodi consequat. Quis aute iure reprehenderit in voluptate velit regards, K. ---line-of-funny-characters-####### example inc. 33 evil street, london mobile: 00 234534/234345 Ideally the algorithm would match only the bold parts. Is there any recommended approach - or are there even existing algorithms for that problem? Should I try approximate regular expressions or more statistical stuff based on number of punctation marks, length and so on?

  • What to store at application Settings, numeric / string representations or objects?

    - by SoMoS
    Hello, I've been thinking for a while on what to store at the Project Settings, objects or numeric/string representations of those objects to set a rule and avoid thinking on this at the future so I want to take the best approach. On one side storing object representations grants you that what is stored is valid and saves you from doing conversions each time you access them. You only need objects with the attribute. At the other side storing the numeric/string representation of an object eases the editing of the setting because at the end the user will be entering numeric or string information. What do you do with this issue?

  • Show UIView for app presentation only once in iOS

    - by André Muniz
    I need to show an UIScrollView with some pages for present the app to user when launched for the first time. My slides are working correctly, lefting the logic to present it.

If there is a better way to do this can someone help? Thanks.

  • Javascript: gradually adding to string in each iteration ?

    - by Kim Jong Woo
    I have a string like this that is split up: var tokens = "first>second>third>last".split(">"); What I would like in each iteration is for it to return Iteration 0: "last" Iteration 1: "third>last" Iteration 2: "second>third>last" Iteration 3: "first>second>third>last" I am thinking of using decrementing index for loop.... but is there a more efficient approach ? for (int w = tokens.length-1; w == 0; w--) { }

  • Do you take the pain of learning it or use an out of the box solution?

    - by Mantorok
    Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

  • What is the best way to migrate documents into Sharepoint (MOSS) 2007?

    - by Jeramie Mercker
    I'm working with a customer that needs to migrate documents from their current document management system (not Sharepoint) into Sharepoint MOSS 2007 retaining document history and metadata. I've written a proof of concept using the Sharepoint web services and that looks promising, but the snag so far seems to be programmatically setting the created date/time and user. The webservices allow the fields to be set but implicitly override them to be the currently logged in user + date/time. For obvious reasons, I need to be able to keep the original created date/time and user on migration. Does anyone know the best way to approach this problem?

  • Clean Method for a ModelForm in a ModelFormSet made by modelformset_factory

    - by Salyangoz
    I was wondering if my approach is right or not. Assuming the Restaurant model has only a name. forms.py class BaseRestaurantOpinionForm(forms.ModelForm): opinion = forms.ChoiceField(choices=(('yes', 'yes'), ('no', 'no'), ('meh', 'meh')), required=False, )) class Meta: model = Restaurant fields = ['opinion'] views.py class RestaurantVoteListView(ListView): queryset = Restaurant.objects.all() template_name = "restaurants/list.html" def dispatch(self, request, *args, **kwargs): if request.POST: queryset = self.request.POST.dict() #clean here return HttpResponse(json.dumps(queryset), content_type="application/json") def get_context_data(self, **kwargs): context = super(EligibleRestaurantsListView, self).get_context_data(**kwargs) RestaurantFormSet = modelformset_factory( Restaurant,form=BaseRestaurantOpinionForm ) extra_context = { 'eligible_restaurants' : self.get_eligible_restaurants(), 'forms' : RestaurantFormSet(), } context.update(extra_context) return context Basically I'll be getting 3 voting buttons for each restaurant and then I want to read the votes. I was wondering from where/which clean function do I need to call to get something like: { ('3' : 'yes'), ('2' : 'no') } #{ 'restaurant_id' : 'vote' } This is my second/third question so tell me if I'm being unclear. Thanks.

  • Android: Using MediaRecorder to crop an existing audio file?

    - by user141146
    Hi, I'd like to take an existing mp3 file located on an SD card and arbitrarily crop it (e.g. crop from 0:12 to 1:14 in a 3 minute song). The only class that I've seen that seems remotely relevant to do this is the MediaRecorder class. My 'hope' would be to "record" an existing file like this: MediaRecorder recorder = new MediaRecorder(); recorder.setAudioSource(###some magical way of specifying an existing file??###); But this obviously doesn't work (setAudioSource() takes an int and seems to default to the phone's microphone). Is there a class or an approach that can be used to crop audio on the phone itself? TKS!!

  • How to do steps of an API through CLI

    - by Dolphin
    I'm using Audiveris API to generate xml(MusicXML) file once the sheetmusic(e.g. pdf/img file) is being input (i.e. When I give the sheet music (pdf file) location, to generate the xml file out of it (in another location)). Audiveris has its own GUI to do this. But can I do this process of sheetmusic-to-xml without using their GUI, but only from the CLI? If so how may I approach it? And also if so - is there a possibility to make it work in CLI - using Java code (say to invoke steps for API to occur in the CLI using Java Code)? I managed to open the GUI by opening the jar file from CLI. But I need to know whether there's a possibility to carry out the sheetmusic(say pdf)-to-xml process without using their GUI, but only through CLI? Greatly appreciate any help or guidance Thanks in advance

  • How to display SUM fields from a detailed table in a master table

    - by max
    What is the best approach to display the summery of DETAILED.Fields in its master table? E.g. I have a master table called 'BILL' with all the bill related data and a detailed table ('BILL_DETAIL') with the bill detailed related data, like NAME, PRICE, TAX, ... Now I want to list all BILLS, without the details, but with the sum of the PRICE and TAX stored in the detail table. Here is a simplified schema of that tables: TABLE BILL ---------- - ID - NAME - ADDRESS - ... TABLE BILL_DETAIL ----------------- - ID - BILLID - PORDUCT_NAME - PRICE - TAX - ... The retrieved table row should look like this: BILL.CUSTOMER_NAME, BILL.CUSTOMER_ADDRESS, sum(BILL_DETAIL.PRICE), sum(BILL.DETAIL.TAX), ... Any sugguestions?

  • Changing the style attribute of a button according to its state

    - by LambergaR
    I know you can change buttons background by creating a simple XML file, like this: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_window_focused="false" android:state_enabled="true" android:drawable="@drawable/button_normal" /> <!-- ... --> </selection> I was wondering if it is possible to use a similar approach to change the style attribute of an element using the same (or similar) technique. Or, if that is not possible, how can the style attribute be changed during runtime (there is no such thing as button.setStyle(R.style.button)).

  • How to use R-Tree for plotting large number of map markers on google maps

    - by Eeyore
    After searching SO and multiple articles I haven't found a solution to my problem. What I am trying to achieve is to load 20,000 markers on Google Maps. R-Tree seems like a good approach but it's only helpful when searching for points within the visible part of the map. When the map is zoomed out it will return all of the points and...crash the browser. There is also the problem with dragging the map and at the end of dragging re-running the query. I would like to know how I can use R-Tree and be able to achieve the all of the above.

    Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.
