  • Using regular expressions to remove relative path slashes

    - by Adam Carlile
    Hey Guys I am trying to remove all the relative image path slashes from a chunk of HTML that contains several other elements. For example <img src="../../../../images/upload/1/test.jpg /> would need to become <img src="http://s3.amazonaws.com/website/images/upload/1/test.jpg" /> I was thinking of writing this as a rails helper, and just passing the entire block into the method, and make using Nokogiri or Hpricot to parse the HTML instead, but I don't really know. Any help would be great Cheers Adam

  • Sphinx, reStructuredText show\hide code snippets

    - by Adam Matan
    Hi, I've been documenting a software package using Sphinx and reStructuredText. Within my documents, there are some long code snippets. I want to be able to have them hidden as default, with a little "Show\Hide" button that would expand them (Example). Is there a standard way to do that? If not, I think I will suggest this feature to the developers. Thanks, Adam

  • Intro to GPU programming

    - by Adam Davis
    Everyone has this huge massively parallelized supercomputer on their desktop in the form of a graphics card GPU. What is the "hello world" equivalent of the GPU community? What do I do, where do I go, to get started programming the GPU for the major GPU vendors? -Adam

  • Pythonic reading from config files

    - by Adam Matan
    Hi, I have a python class which reads a config file using ConfigParser: Config file: [geography] Xmin=6.6 Xmax=18.6 Ymin=36.6 YMax=47.1 Python code: class Slicer: def __init__(self, config_file_name): config = ConfigParser.ConfigParser() config.read(config_file_name) # Rad the lines from the file self.x_min = config.getfloat('geography', 'xmin') self.x_max = config.getfloat('geography', 'xmax') self.y_min = config.getfloat('geography', 'ymin') self.y_max = config.getfloat('geography', 'ymax') I feel that the last four lines are repetitive, and should somehow be compressed to one Pythonic line that would create a self.item variable for each item in the section. Any ideas? Adam

  • ASP.NET MVC framework port for Java EE?

    - by Adam Asham
    So I've played some with the new, not yet final release of ASP.NET MVC framework and I find it to be very nice and elegant. However at work we are tied to Java for the time being, so I'm wondering this: is there a port of the framework out there for Java people like myself? I realize that webforms isn't going to be available unfortunately but what about the routing framework? /Adam

  • Python: using doctests for classes

    - by Adam Matan
    Hi, Is it possible to use Python's doctest concept for classes, not just functions? If so, where shall I put the doctests - at the class' docstring, or at the constructor's docstring? To clarify, I'm looking for something like: class Test: """ >>> a=Test(5) >>> a.multiply_by_2() 10 """ def __init__(self, number): self._number=number def multiply_by_2(self): return self._number*2 Thanks in advance, Adam

  • Changing IIS URL Rewrite config location

    - by adam
    Hi When used at site level, the IIS7 URL Rewrite 2 module saves its configuration in the web.config file of that site. I'm using Sitecore CMS, and best practice is to store any web.config customisations in a separate config file for ease of upgrading, staging/production setups etc. Is there any way to specify a different config file for IIS7 redirects? I know that application-level rewrites are stored in ApplicationHost.config, but I have several sites running on the server and would like to keep them separated. Thanks, Adam

  • Google Maps iPhone API Terrain View

    - by Adam
    We're using MapKit on an iPhone app to display a Google Map with terrain view. However, the terrain view only shows when the user has an active Internet connection, the moment the user's Internet is off, the terrain on the map disappears and it appears flat. Is there any way to keep the terrain view on even when the user isn't on an active internet connection? Thanks! Adam

  • eclipse+bzr (Or: DVCS + IDE)

    - by Adam Matan
    Hi, I have some projects on bzr code repositories shared with colleagues. Problem is, I really want to switch to eclipse in some projects, but I don't want to pollute the repository with the unnecessary metadata eclipse creates in its Workspaces. Any idea how to keep Eclipse's metadata outside my bzr repo? Adam

  • PostgreSQL: SELECT all fields, filter some

    - by Adam Matan
    Hi, In one of our databases, there is a table with dozens of columns, one of which is a geometry column. I want to SELECT rows from the table, with the geometry transformed to another SRID. I want to use something like: `SELECT *` in order to avoid: SELECT col_a, col_b, col_c, col_d, col_e, col_f, col_g, col_h, transform(the_geom, NEW_SRID), ..., col_z Any ideas? Adam

  • Win32: How do I get the listbox for a combobox

    - by Adam Tegen
    I'm writing some code and I need to get the window handle of the listbox associated with a combo box. When looking in spy++, it looks like the parent of the listbox is the desktop, not the combo box. How can I programmatically find the listbox window handle? I know I'd be looking for a window class of ComboLBox that belongs to my process, but how do I narrow that down to the specific one I am looking for? Adam

  • When learning C, should one only refer to resources published from 2007 onward?

    - by Adam Siddhi
    I ask this question because the international standardization subcommittee for programming languages, or ISO/IEC JTC1/SC22 Programming languages, states on this page: http://www.open-std.org/JTC1/SC22/WG14/www/standards that Technical Corrigendum 3, the latest one, was published in 2007. Now I take it that this means the C language it self was changed and that the books and tutorials pre-2007 may contain outdated information. Please correct me if I am wrong. Thanks, Adam

  • Why did Dylan lose to Objective-C

    - by Adam Gent
    I have played/worked with many different programming languages and Dylan is still one of my favorites. My question is why did Dylan fail when Objective-C, Ruby and even Scheme have had more success? Was Dylans performance that much worse than Objective-C that Apple went with it or was purely for social/political reasons. Hopefully someone from apple will see this question :) BTW if you have no idea what Dylan is please google Dylan Progrmaming Language.

  • Handling incremental Data Modeling Changes in Functional Programming

    - by Adam Gent
    Most of the problems I have to solve in my job as a developer have to do with data modeling. For example in a OOP Web Application world I often have to change the data properties that are in a object to meet new requirements. If I'm lucky I don't even need to programmatically add new "behavior" code (functions,methods). Instead I can declarative add validation and even UI options by annotating the property (Java). In Functional Programming it seems that adding new data properties requires lots of code changes because of pattern matching and data constructors (Haskell, ML). How do I minimize this problem? This seems to be a recognized problem as Xavier Leroy states nicely on page 24 of "Objects and Classes vs. Modules" - To summarize for those that don't have a PostScript viewer it basically says FP languages are better than OOP languages for adding new behavior over data objects but OOP languages are better for adding new data objects/properties. Are there any design pattern used in FP languages to help mitigate this problem? I have read Phillip Wadler's recommendation of using Monads to help this modularity problem but I'm not sure I understand how?

  • Track pageviews in Google Analytics on partial url of Grails application

    - by Pieter van Gent
    For my Grails application I want to set up Google Analytics to track only "partial" url's. I 'll explain: a typical Grails url consists of the following parts: domain + application-name + controller + action + id e.g. www.mydomain.com/myapp/controller/action/12345 As far as I understand for Google Analytics the page to be tracked is identified by the entire url. For my purpose I'm not interested in the id part of the url: I want to know which actions have been performed, but I need not know for which id the action was executed. And of course I would like a generic solution, because I have multiple controllers and multiple actions... Maybe some kind of filter stating "I want to track pages 3 levels deep (/myapp/controller/action)" would do? Or a filter stating "exclude everything from url after the last /"? Any help would be much appreciated. Kind regards, Pieter

  • How do I do automatic data serialization of data objects in Haskell

    - by Adam Gent
    One of the huge benefits in languages that have some sort of reflection/introspecition is that objects can be automatically constructed from a variety of sources. For example in Java I can use the same objects for persisting to a db (with Hibernate) serializing to XML (with JAXB) or serializing to JSON (json-lib). You can do the same in Ruby and Python also usually following some simple rules for properties or annotations for Java. Thus I don't need lots "Domain Transfer Objects". I can concentrate on the domain I am working in. It seems in very strict FP like Haskell and Ocaml this is not possible. Particularly Haskell. The only thing I have seen is doing some sort of preprocessing or meta-programming (ocaml). Is it just accepted that you have to do all the transformations from the bottom upwards? In other words you have to do lot of boring work to turn a data type in haskell into JSON/XML/DB Row object and back again into a data object.

  • Single page Web App in Java framework or examples?

    - by Adam Gent
    Has anyone seen an example or done the following in Java: http://duganchen.ca/single-page-web-app-architecture-done-right/ That is a design a single page web app that will work with Google SEO with out massive violation of DRY using Java technologies? It doesn't seem terrible hard to do this on my own but I was curious (and lazy) to see if someone had already done it with either Spring or JAX-RS.

  • Commutative (operational transform) diffs for databases

    - by barrycarter
    What Unix program generates "diff"s between text files (or INSERT/UPDATE/DELETEs for databases) in such a way that the order that the "diff"s are applied in is irrelevant, and the result is the same regardless of order. Etherpad used to do something like this. Example (for a given document or database): % Adam makes a change X, then Bob makes a change Y, then Adam makes another change Z. % However, because of network latency, Adam sees the changes in this order: XZY, while Bob sees them in this order: YXZ. % However, the code/changes are written so that XYZ and YXZ yield the same result. Note: ideally, this can be done without having to do X/Y/Z inverse at any point. I have read http://stackoverflow.com/questions/2043165/operational-transformation-library but I'm not sure this really does what I want.

  • In Java it seems Public constructors are always a bad coding practice

    - by Adam Gent
    This maybe a controversial question and may not be suited for this forum (so I will not be insulted if you choose to close this question). It seems given the current capabilities of Java there is no reason to make constructors public ... ever. Friendly, private, protected are OK but public no. It seems that its almost always a better idea to provide a public static method for creating objects. Every Java Bean serialization technology (JAXB, Jackson, Spring etc...) can call a protected or private no-arg constructor. My questions are: I have never seen this practice decreed or written down anywhere? Maybe Bloch mentions it but I don't own is book. Is there a use case other than perhaps not being super DRY that I missed? EDIT: I explain why static methods are better. .1. For one you get better type inference. For example See Guava's http://code.google.com/p/guava-libraries/wiki/CollectionUtilitiesExplained .2. As a designer of the class you can later change what is returned with a static method. .3. Dealing with constructor inheritance is painful especially if you have to pre-calculate something.
