  • Idiomatic approach for structuring Clojure source code

    - by mikera
    I'm interested in how people structure their Clojure source code. Being used to Java, I'm pretty familiar with the paradigm of one class per source code file, bundling all the data and method definitions with appropriate comments and annotations etc. However Clojure offers a lot more flexibility, and I'm not sure how I should structure my project (likely to end up as a medium sized app, maybe 5,000 lines with three or four distinct subsystems) In particular I'm wrestling with: What guidelines should I use to determine whether code should be in a single namespace vs. separated out into different namespaces? Should each protocol/datatype have it's own namespace + source file with associated set of functions? When should I require vs. use other namespaces?

  • Is it possible to preg replace unique variables into a string?

    - by Scarface
    What I want to do is use preg replace to replace matches within a string with a varying replacement, and I was wondering if anyone knew if that is possible in php or at least achievable by some means. For example, a string has two matches, then those matches will be replaced with two different variables. What I want are replacements to each be a unique id and I cannot figure out how this could possibly work or if php could even do this. For example if the match is 'a' and there is a sentence, 'put a smile on a person' then one 'a' will be unique id 98aksd00 and the other will be 09alkj08. I am retrieving my comments from a database so the preg replace is happening within while ($row=mysql_fetch_assoc($query)){ //preg replace If anyone could provide any insight into this, I would really appreciate it

  • SaaS Multi-tenancy Applications: How is data import/export/backup being implemented?

    - by Mark Redman
    How are applications providing import / export (or backups) of data in SaaS based multi-tenancy applications, particularly single database designs? Imports: Keeping things simple I think basic imports are useful, ie CSV to a spec (or a way of providing a mapping between CSV columns and fields in the database. Exports: In single database designs I have seen XML exports and HTML (basic sitse generated) exports of data? I would assume that XML is a better option? How does one cater for relational data? Would you reference various things within XML and provide documentation of the relationships or let users figurethis out? Are vendors providing an export/backup that can be imported back in/restored? Your comments appreciated.

  • How to set background image in Java?

    - by Dew
    I am developing a simple platform game using Java using BlueJ as the IDE. Right now I have player/enemy sprites, platforms and other items in the game drawn using polygons and simple shapes. Eventually I hope to replace them with actual images. For now I would like to know what is the simplest solution to setting an image (either URL or from local source) as the 'background' of my game window/canvas? I would appreciate it if it isn't something long or complex as my programming skills aren't very good and I want to keep my program as simple as possible. Kindly provide example codes with comments to elaborate on their function, and also if it's in its own class, how to call on relevant methods used by it on other classes. Thank you very much.

  • xml to xsd to c# class - C# 3.0, .net 3.5

    - by uno
    Following this articlelink text one of the comments from 'zanoni' said he did it this way Using .NET 3.5: [XmlRoot] public class EmailConfiguration { [XmlElement] public string DataBoxID { get; set; } [XmlElement] public DefaultSendToAddressCollectionClass DefaultSendToAddressCollection { get; set; } } public class DefaultSendToAddressCollectionClass { [XmlElement] public string[] EmailAddress { get; set; } } How would I get my class to be as what he described?

    - by melaos
    hi is there a tool that i can use to generated msdn type documentation? i recently just started playing with sandcastle and i found that there used to a tool called scriptdoc but it has been absorbed into aptana and i don't really want to use aptana studio. what i could find so far is jsdoc which is a perl script which extracts comments from javascript files but i'm still looking for a better fit. from my initial testing it seems that the xml generated from jsdoc doesn't match completed with sandcastle or maybe i'm missing something there... any help?

  • what is the best and valid way for cross browser min-height?

    - by metal-gear-solid
    for #main-content I don't want to give any fix height because content can be long and short but if content is short then it should take minimum height 500px. i need compatibility in all browser. Is thery any w3c valid and cross browser way without using !important because i read !important should not be used In conclusion, don’t use the !important declaration unless you’ve tried everything else first, and keep in mind any drawbacks. If you do use it, it would probably make sense, if possible, to put a comment in your CSS next to any styles that are being overridden, to ensure better code maintainability. I tried to cover everything significant in relation to use of the !important declaration, so please offer comments if you think there’s anything I’ve missed, or if I’ve misstated anything, and I’ll be happy to make any needed corrections. http://www.impressivewebs.com/everything-you-need-to-know-about-the-important-css-declaration/

  • Should we use a CSS frame work ? Are they worth it ?

    - by Gaurav M
    CSS frameworks have nice styles inbuilt and ask you to focuses on the grids but still there is a bit of dependency and lack of freedom it provide.. If I need to generate a webpage by looking on a PSD based mockup screen ..either i will use the classes provided by the framework but if that actual measurements does not exist I need to again specify my own rules that will add upto my CSS filesize and if performance is a constraint as always it is...you need not a big size file..though its in kb but every drop counts. Any comments and suggestions to use the framework in a best possible way.

  • Matlab: How to find the right-most point of a white line within the imrect?

    - by mchlfchr
    i've got a question regarding the imrect() function, which is part of the image processing toolbox in MatLab. I'd like to find a starting point within an image. I use the imrect function for setting a region to limit and specify the lookup area, but I can't get the point where the ROI mask is getting back mapped to the original size of the image. As you can see on the image there is a specified rectangle (cyan-colored), which I want to inspect for the white line, especially the nearest point to the right edge of the rectangle. I experimentated with only looking up on the last column of the rectangle, but as I mentioned before, the re-mapping onto the global image coordinates failed. So in this example, the white point I'd like to get would be around (98,302) The original (x,y) coordinates are relevant, so a cropping of the image to the rectangle is not acceptable. So, do you have any ideas? Thanks for any helping comments. Kind regards,

  • What's your favorite programmable calculator?

    - by Pat Notz
    The HP-32S still holds a soft spot in my heart, even though it only had 4 registers. I have fond memories of writing a nonlinear solver for finding an azeotrope curve during a Thermodynamics final. Despite the increase in power, memory, pixels and features the HP-32G that followed never could steal my heart away. Here's to you, HP-32S. Let's hear it, what's your favorite programmable calculator? As with all poll type questions, do NOT submit a new answer unless your answer is not represented. Vote up your answer instead of adding yet another TI-85 or HP-49 to the list, and add comments to that answer if you want to relate specifics. EDIT: I moved my photo into an answer for polling.

  • Regex problem ...

    - by carlos
    hello i have the next regex Dim origen As String = " /c /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt"" /cid:45 423 /z:65 /a:23 /m:39 /t:45rt " Dim str As String = "(^|\s)/p:""\w:(\\(\w+[\s]*\w+)+)+\\\w+.\w+""(\s|$)" Dim ar As Integer Dim getfile As New Regex(str) Dim mgetfile As MatchCollection = getfile.Matches(origen) ar = mgetfile.Count When i evaluate this it works, and gets the /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt"" that basically is the path to a file. But if I change the origen string to Dim origen As String = " /c /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt""/cid:45 423 /z:65 /a:23 /m:39 /t:45rt " Check that the end of the file is follow by "/cid:45" whitchs makes de patter invalid, but insted of getting a mgetfile.count = 0 the program is block, if i make a debug I got a property evaluation failed. Thanks for your comments !!!

  • Overloading Controller Actions

    - by DaveDev
    Hi Guys I was a bit surprised a few minutes ago when I tried to overload an Action in one of my Controllers I had public ActionResult Get() { return PartialView(/*return all things*/); } I added public ActionResult Get(int id) { return PartialView(/*return 1 thing*/); } .... and all of a sudden neither were working I fixed the issue by making 'id' nullable and getting rid of the other two methods public ActionResult Get(int? id) { if (id.HasValue) return PartialView(/*return 1 thing*/); else return PartialView(/*return everything*/); } and it worked, but my code just got a little bit ugly! Any comments or suggestions? Do I have to live with this blemish on my Controllers? Thanks Dave

  • Get data from html form to ruby in Ruby on Rails

    Get data from html form to ruby in Ruby on Rails I have some html like this <html> <h1>Text to PDF</h1> <textarea name="comments" cols="40" rows="5"> Enter your Text here... </textarea><br> <input type="submit" value="Submit" /> </form> </body> </html> I want to give the value of the text into the controller for this page/view. How do I do this with rails? I am new to rails, what is the mechanism for this? I don't need to write to the database just want to hand it to the controller. If there is a good tutorial for this sort of thing that would be great, I am not convince I am approaching this correctly.

  • @Resource annotated member not injected - bad code or bug?

    - by Brabster
    I am using an @Resource annotation in a class instantiated in a ServletContextListener's contextInitialized(...) method, but the member is always null. Here's my sample code. Listener: public void contextInitialized(ServletContextEvent sce) { System.err.println("In contextInitialised"); new ResourceListenerTargetTest().executeMe(); } ResourceListenerTargetTest: @Resource(name="MyJDBCResource") private DataSource source; public void executeMe() { /*try { InitialContext ictx = new InitialContext(); source = (DataSource)ictx.lookup("java:comp/env/MyJDBCResource"); } catch (NamingException e) { e.printStackTrace(); }*/ System.err.println("source is " + source); } If I switch the comments and run the manual resource lookup, it works fine. Should the @Resource annotation work like this, when used in a contextInitalized method? Appserver is WAS 7.0.0.5, if it should work then I guess it's a bug? Can anyone confirm?

  • Literate Haskell (.lhs) and Haddock

    - by finnsson
    At the moment I'm only using Haddock but after seeing some really interesting examples (e.g. this gist ) of literate Haskell I'm interested in trying it out in a project. The questions I got are: What do you write as Haddock comments and what do you write in the literate part? How do you scale literate programming to multiple files? Can anyone point me to an example where literate programming is used in a package with multiple modules? What is your experience of using literate programming in larger packages? Which flavour (markdown, latex, ...) of literate Haskell is preferred? Why are you programming in literate Haskell or plain vanilla Haskell? Are you programming in both styles and if so why? Do you prefer block-style (\begin{code}) or Bird-style (>)? Why?

  • OpenID PAM module

    - by Harvey Kwok
    I am looking for a PAM module that can use OpenID to do the authentication. My idea is that I want to logon my Linux box using my gmail account and password. I found there is a open source project in Google Code which seems to be doing the things I want but I don't see any code available for download. I saw there are so many examples or implementations but they are all about web apps. Is there any non-web based OpenID applications in the world? Is it technically possible to make a non-web based OpenID application? I naively think that it should be possible. I can emulate whatever packets the browser send out to the OpenID provider and get back the result. As long as my Linux box is connected to the Internet, I should be able to use my OpenID to login. Appreciate any comments, suggestions or pointers on how to make an OpenID PAM module. Thanks!

  • Scala downwards or decreasing for loop?

    - by Felix
    In scala, you often use an iterator to do a for loop in an increasing order like: for(i <- 1 to 10){ code } How would you do it so it goes from 10 to 1? I guess 10 to 1 gives an empty iterator (like usual range mathematics)? I made a scala script which solves it by calling reverse on the iterator, but it's not nice in my opinion, is this the way to go: def nBeers(n:Int) = n match { case 0 => ("No more bottles of beer on the wall, no more bottles of beer."+ "\nGo to the store and buy some more, "+ "99 bottles of beer on the wall.\n") case _ => (n+" bottles of beer on the wall, "+n +" bottles of beer.\n"+"Take one down and pass it around, "+ (if((n-1)==0) "no more" else (n-1))+ " bottles of beer on the wall.\n") } for(b <- (0 to 99).reverse)println(nBeers(b)) ?? Any comments/suggestions?

  • Painless way to install a new version of R?

    - by Shane
    Andrew Gelman recently lamented the lack of an easy upgrade process for R (probably more relevant on Windows that Linux). Does anyone have a good trick for doing the upgrade, from installing the software to copying all the settings/packages over? This suggestion was contained in the comments and is what I've been using recently. First you install the new version, then run this in the old verion: #--run in the old version of R setwd("C:/Temp/") packages <- installed.packages()[,"Package"] save(packages, file="Rpackages") Followed by this in the new version: #--run in the new version setwd("C:/Temp/") load("Rpackages") for (p in setdiff(packages, installed.packages()[,"Package"])) install.packages(p)

  • Delphi JavaDoc Parser

    - by Christian Sciberras
    I need to parse JavaDoc (documentation) comment syntax with Delphi 7. It is well known in the java world as "JavaDoc", but I'm actually doing this for PHP, ie, parsing JavaDoc in some PHP code. Call it PHPDoc if you want to. To see how these comments work, you can see RAD IDEs like NetBeans etc. Example of JavaDoc for addition function: /** * Adds to numbers together. * @param integer $a The first number. * @param integer $b The second number. * @return integer The resulting number. */ function add($a,$b){ return $a+$b; } Please note that the parser need not be full, ie, parsing all of the PHP code. I mean, it's perfectly fine if it accepted the comment text only as input. Cheers, Chris.

  • Custom session state provider needed for DB storage?

    - by subt13
    I know this question is related to many others, but please bear with me. I am trying an experiment to store all information in database tables instead of the ASP.NET session. In ASP.NET 4 one can create a custom provider for session. So, again should I implement a Custom Session-State Provider or should I just disable session (in Web.config)? Thanks! From the comments my question can be misunderstood. Hopefully this tidbit will help clarify: I don't want to store the session in the database. I want to store information in the database that you would typically store in the session. One reason why: I don't want to carry around a session on every page, especially if that page doesn't care about 90 percent of the information in the session

  • removing dashboard menu options for the user role editor

Ive also got this snippet of code but dont know how to combine it with what I have: $editor = get_role(‘editor’); $editor->remove_cap(‘publish_pages’);

  • How does the Amazon Recommendation feature work?

    What technology goes in behind the screens of Amazon recommendation technology? I believe that Amazon recommendation is currently the best in the market, but how do they provide us with such relevant recommendations? Recently, we have been involved with similar recommendation kind of project, but would surely like to know about the in and outs of the Amazon recommendation technology from a technical standpoint. Any inputs would be highly appreciated. Update: This patent explains how personalized recommendations are done but it is not very technical, and so it would be really nice if some insights could be provided. From the comments of Dave, Affinity Analysis forms the basis for such kind of Recommendation Engines. Also here are some good reads on the Topic Demystifying Market Basket Analysis Market Basket Analysis Affinity Analysis Suggested Reading: Data Mining: Concepts and Technique
