  • best way to write a-> ..->[a] recursive functions in haskell

    - by Roman A. Taycher
    So I keep having this small problem where I have something like func :: a -> b -> [a] -- or basically any a-> ...-> [a] where ... is any types -> func x y = func' [x] y -- as long as they are used to generate a list of [a] from x func' :: [a] -> b -> [a] func = undefined --situation dependant generates a list from each element and returns it as one long list should I keep it like this? should I use func' hidden by a where? should I only use the [a] - b - [a] version and leave the responsibility of passing [variable] to the callee? I might well need to compose these functions and might want to mess around with the order so I'm leaning towards option 3. What do you think?

  • Insert into select and update in single query

    - by Ossi
    I have 4 tables: tempTBL, linksTBL and categoryTBL, extra on my tempTBL I have: ID, name, url, cat, isinserted columns on my linksTBL I have: ID, name, alias columns on my categoryTBL I have: cl_id, link_id,cat_id on my extraTBL I have: id, link_id, value How do I do a single query to select from tempTBL all items where isinsrted = 0 then insert them to linksTBL and for each record inserted, pickup ID (which is primary) and then insert that ID to categoryTBL with cat_id = 88. after that insert extraTBL ID for link_id and url for value. I know this is so confusing, put I'll post this anyhow... This is what I have so far: INSERT IGNORE INTO linksTBL (link_id,link_name,alias) VALUES(NULL,'tex2','hello'); # generate ID by inserting NULL INSERT INTO categoryTBL (link_id,cat_id) VALUES(LAST_INSERT_ID(),'88'); # use ID in second table I would like to add here somewhere that it only selects items where isinserted = 0 and iserts those records, and onse inserted, will change isinserted to 1, so when next time it runs, it will not add them again.

  • Documenting an existing website (symfony)

    - by Mark Blades
    Hi, I need to document a web application which wasn't built by me. It was built in symfony. The documentation needed is code documentation, including list/description of classes, components etc and their interdependencies. At the moment the code isn’t commented much and the way it has been commented is inconsistent. I was thinking of using Doxygen to generate initial documentation and then take it from there. Any other suggestions? Thanks in advance. Mark.

  • LINQ to SQL, how to write a method which checks if a row exists when we have multiple tables

    - by Beles
    Hi, I'm trying to write a method in C# which can take as parameter a tabletype, column and a columnvalue and check if the got a row with a with value the method looks like: public object GetRecordFromDatabase(Type tabletype, string columnname, string columnvalue) I'm using LINQ to SQL and need to to this in a generic way so I don't need to write each table I got in the DB. I have been doing this so far for each table, but with more than 70 of these it becomes cumbersome and boring to do. Is there a way to generate the following code dynamically, And swap out the hardcoded tablenames with the values from the parameterlist? In this example I have a table in the DB named tbl_nation, which the DataContext pluralizes to tbl_nations, and I'm checking the column for the value if (DB.tbl_nations.Count(c => c.code.Equals(columnvalue)) == 1) { return DB.tbl_nations.Single(c => c.code.Equals(columnvalue)); }

  • what are the various approaches for generating PDFs?

    - by andthereitgoes
    I have an idea for an app that would take some flash content which contains graphics and images like various geometric shapes and polygons and some random images and convert them to PDF. Also, since I envision this app to be used my multiple users I want this process to be quick and scalable. One possible solution I could think of is have a small flash client with the capability of assembling the above mentioned graphics and images. Generate some sort of XML, send it to a server running a Java process which could render the PDF using iText. I was wondering what are the other possible ways to do it or the best practices. Technology isn't an issue; open source or commercial. I am looking for ideas to make the process fast and scalable. Most importantly, I don't want the back end server side PDF render engine to constraint the flash client capabilities. I would appreciate if you could share your tech stack idea. Thanks a lot!

  • JclLastExceptStackListToStrings produces an empty string list

    - by Max
    I've installed JCL into Delphi 2010. In the following code try raise Exception.Create('Error Message'); except on E: Exception do begin ResultStatus := JclLastExceptStackListToStrings(sl, True, True, True, True); end; end; Also I have this call in the initialization section: initialization JclStartExceptionTracking; ResultStatus is false and sl is empty. I have set options to generate map and .jdbg files. Other functions, like ProcByLevel work fine. Is there something else I need to do to make JclLastExceptStackListToStrings work?

  • Most efficient method of generating PNG as HTTP response

    - by awj
    I've built an ASP.NET page whose output stream is a dynamically-generated PNG image containing only text on a transparent background. The text is based upon database IDs contained in the querystring. There will be a limited number of variations. Which one of the following would be the most efficient means of returning the image to the client? Store each variation upon the first generation, and thenceforth retrieve this from the drive. Simply generate the image each time. Cache the output response based upon the querystring.

  • Is there any way to use imagegrabwindow() with Firefox or Chrome?

    - by patternsofchaos
    I'm trying to generate website thumbnails programatically in PHP. To do this, I'm using imagegrabwindow() with a COM object: $browser = new COM("InternetExplorer.Application"); $handle = $browser->HWND; $browser->Visible = true; $browser->Navigate($pre.$URL); while ($browser->Busy) { com_message_pump(4000); } $img = imagegrabwindow($handle); What I'm wondering is if there is any way to do the same thing with Firefox or Chrome? Can I invoke either of them with PHP COM?

  • Annotation retention policy: what real benefit is there in declaring `SOURCE` or `CLASS`?

    - by watery
    I know there are three retention policies for Java annotations: CLASS: Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time. RUNTIME: Annotations are to be recorded in the class file by the compiler and retained by the VM at run time, so they may be read reflectively. SOURCE: Annotations are to be discarded by the compiler. And although I understand their usage scenarios, I don't get why it is such an important thing to specify the retention policy that retention policies exist at all. I mean, why aren't all the annotations just kept at runtime? Do they generate so much bytecode / occupy so much memory that stripping those undeclared as RUNTIME does make that much difference?

    - by orangebrainer
    I'm trying to create hidden iframes in my page dynamically to load 3 other pages so that i can grab all the HTML and combine them into 1 in a new window. However i'm stuck at this. tHe frames are created fine.

  • Design ideas for

    - by ZeroVector
    I need to design and I'm looking in to using WCF to accomplish this. Basically here is how I have it: Server process: Generate list of files to transfer across multiple FTP/SFTP sites in to a queue. Client(s): Talk to server to get files to transfer. Transfer the files acquired. All the data necessary to transfer the files will be present. Once transferred successfully, notify the server to remove it from the queue. Also, make sure no other client is trying to perform the transfer. Are there are any good articles/design patterns to use? I think it sounds like a good candidate for WCF since ideally it would be load balanced against a few machines. Development will be in C#/.NET 3.5.

  • JS/PHP: Who is responsible for generating the content?

    - by Extrakun
    Here's a situation which I have encountered, creating a form on the client side and using PHP to process. Here are some considerations The PHP script generates the form and send to the client side. This is because of internationalization issues The client side uses JavaScript to submit form; the ID of the form is hard-coded inside the JavaScript as it is generated by PHP. This means everytime the PHP code is updated, the JS must change. The question here is, who should be dependent on who? Should the JS generate the form instead, so that the PHP script has to know the names of the form elements? OR should it be the other way round?

  • How to update JLabel in Swing?

    - by Roman
    I am trying to use Swing Timer and I wanted to start from a very simple program. I have a window with text: "You have n seconds", where n changes from 10 to 0 every second. I know how to generate a window with text. And I understand how Timer works (it starts an action periodically). But I cannot figure out how to combing this two things. Should I use that: JLabel label = new JLabel(myMessage); and then with timer I need to update the "myMessage" variable? But I think I need to "force" my window to "update" itself (to display a new value stored in "myMessage").

  • How to get the Primary/Secondary color in jQuery UI Theme

    - by simonsanderson
    Is there a way to reference the colours used in the jQuery themes without creating a simple style for each theme that I may choose to use? Example: I have some text as follows <div>Hello</div> which I'd like to be change colour in line with my theme of the day. I wish to use the primary colour from a theme (say ui-lightness) which is "#1c94c4" as defined in several of the styles such as ui-state-default in ui-lightness.css The problem is that if I do the following <div class='ui-state-default'>Hello</div> I get all the other style effects, like borders and background colour, which are not right for my application What I'd like to do is something like <div class='ui-primary-color'>Hello</div> which would automatically change only the colour dependent on the theme. PS. Doing a pre-build pre-processing step to parse the themes and generate a customised css style would be my least favourable option here!

  • Is there a Javadoc-like plugin for Xcode that automatically generates the doc template?

    - by Mark
    I'm aware of Doxygen to generate the documentation. What I'm looking for is quick way to insert documentation in Xcode similar to what Eclipse does when editing Java files. Let's say I have an objective-c method with a couple of arguments like this: -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {... In Eclipse, if you place the cursor above the method and type: /**<Enter> you get a Javadoc template pre-populated with @param and @return tags. Is it possible to achieve something similar in Xcode? After typing /**<Enter>, I'd like to get this automatically: /** * * @param one * @param two * * @return */ -(NSInteger*) sumOf: (NSInteger*) one and:(NSInteger*) two {...

  • .NET web service call slower when performed asynchronously

    - by joelt
    I have an ASP.NET site, and some pages need to call a web service. I used Visual Studio's "Add Web Reference" to auto-generate classes and methods for the web service. When I call the service synchronously, i.e. objService.MethodName("param1"), a call might take a second or so. When I call it asynchronously, i.e., objService.BeginMethodName("param1", AddressOf MyCallback, Nothing), it typically takes about 6 seconds. When debugging, it appears that the bulk of the time is spent waiting between the completion of the BeginMethodName call and the beginning of MyCallback. Does the thread switching really incur that much overhead? Is there another reason for this?

  • Methods of sending web-generated config files to servers and restarting services.

    - by JPG
    Hi, We're writing a web-based tool to configure our services provided by multiple servers. This includes interfaces configuration, dhcp configs etc. etc. Having configs in database and views that generate proper output, how to send it/make it available for servers? I'm thinking about sending it through scp and invoking reload command to services through ssh. I'm also thinking about using Func to do all the job, as this is Python tool and will seemingly integrate with python-based (django) config tool. Any other proposals?

  • Django store regular expression in DB which then gets evaluated on page

    - by John
    Hi, I want to store a number of url patterns in my django model which a user can provide parameters to which will create a url. For example I might store these 3 urls in my db where %s is the variable parameter provided by the user: www.thisissomewebsite.com?param=%s www.anotherurl/%s/ www.lastexample.co.uk?param1=%s&fixedparam=2 As you can see from these examples the parameter can appear anywhere in the string and not in a fixed position. I have 2 models, one holds the urls and one holds the variables: class URLPatterns(models.Model): pattern = models.CharField(max_length=255) class URLVariables(models.Model): pattern = models.ForeignKey(URLPatterns) param = models.CharField(max_length=255) What would be the best way to generate these urls by replacing the %s with the variable in the database. would it just be a simple replace on the string e.g: urlvariable = URLVariable.objects.get(pk=1) pattern = url.pattern url = pattern.replace("%s", urlvariable.param) or is there a better way? Thanks

  • HTML5 - Creating a canvas on top of an SVG(or other image)

    - by cawd
    The reason for asking this question is because I want to be able to draw an arrow between two svg images. I want to use canvas to create the arrows, so firstly I generate the svgs then place a canvas on top of them to be able to draw the arrows. I've tried using style=... but haven't had any luck as everytime I add the canvas element it just pushes my svg images to another pl If there's no easy way to do this I'll just create arrows using SVG, I figured it would be more efficient to use canvas if I had to do lots of arrows in a short amount of time.

  • movedown method not saving new position - cakephp tree

    - by Ryan
    Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

  • For what purposes have YOU used T4?

    - by Chris Melinn
    T4 has existed for several years in Visual Studio, but doesn't get a lot of attention. However, for those that know it, there seems to be some very creative and useful purposes. I am researching some different ways that T4 is used, and I would appreciate to hear how YOU may have used it for real life scenarios. I am primarily interested in non-standard and creative uses. Some interesting examples: Phil Haack uses T4 to create static CSS files from .less To Generate WPF and Silverlight Dependency Properties using T4 Templates Note: I realize this is a discussion-oriented question, but the answers could be helpful to others. I have tagged it as subjective and also marked as "community wiki", so please allow the question to remain open. Thanks!
