  • Determine if a url matches a Route, and pull out the terms if it does

    - by Kevin Montrose
    I've got a big old log file I'm trying to break down in terms of routes. Essentially, I'm getting input of a path (/questions/31415 for example) and a list of all the registered Routes. What I want out is a Route and the parameters specified in the route (so in, /questions/{id}/{answer} I'd get id and answers out). I've got a working solution that basically generates a nasty bit of regex on the fly with named groups to do matching and parsing all-in-one. My gut tells me this is a brittle way to do it, and frankly there has to be a better way, right?

  • Find what unknown function does in C using gdb

    - by Gary
    Hi, I have a function m(int i, char c) which takes and returns a char between "-abc...xyz" and also takes an integer i. Basically I have no way to see the source code of the function but can call it and get the return value. Using gdb/C, what's the best way to decipher what the function actually does? I've tried looking for patterns using consecutive chars and integer inputs but have come up with nothing yet. If it helps, here are some results of testing the return values, with the first two bits being the arguments and the last bit being the return value: 0 a i 0 b l 0 c t 0 d x 0 e f 0 f v 1 a q 1 b i 1 c y 1 d e 2 a a 2 b y 2 c f 2 d n

  • pasteHTML removes markup

    - by ullmark
    I am writing a plugin to an old IE-only WYSIWYG-editor which resides in an old CMS. I've created a plugin that opens an popup where the user kan enter the url of an youtube clip. The popup then creates the corrent <object..><param..> markup for the embed and uses Internet Explorers pasteHTML function; var range = plugin.editorDocument.selection.createRange(); var embedHtml = OpenDialog(dialogUrl, null, 400, 200); if (!embedHtml) { return; } range.pasteHTML(embedHtml); I know it's missing a bit of information about some of the variables but you get the picture. The problem is that the <param>-tags gets removed when i run the pasteHTML. I wonder if anyone have an idea of fixing this, and letting me keep my param-tags

  • .NET Database Apps: Your Preferred Setup

    - by mdvaldosta
    I'm struggling to settle into a pattern for developing typical database driven apps in C# and Visual Studio. There are so many ways to set them up, using drag/drop datasets and adapters or writing the queries manually in ADO.NET or Linq to SQL, Linq to Entities, to bind or not to data bind etc etc. Where to store the connection string, in app.config or in a method or both etc etc. So many tutorials and all of them are different. Everytime I write something I start hating the way it looks and works, so I scrap it and start over. It's getting a bit tedious. Maybe it's alittle of the OCD in me. Would any of you professional developers out there share your method of setting up and structuring your database logic and maybe some sample code? It's really how to go about organizing the code and the method(s) of interacting with SQL that I'm trying to get into a routine with, one that works and won't get me laughed at by someone reviewing it.

  • iPhone: Best Method for Passing Data to and from a Server

    - by SAPNA
    I am developing an iPhone application that downloads data from a website. The website database is implemented in SQL and the site itself uses the classic ASP interface. I am unsure as to which method would be best for transferring data to and from the server. Both JSON and SOAP require XML processing and I'm not sure how that affects performance or which of those two is best. What would be the best method in general for data transfer given the server configuration we currently have? I very new to this field and I'm a bit confused. Any help would be appreciated.

  • Clean Up Controller, Update Item Quantity within Cart

    - by Karl Entwistle
    Hi guys I was wondering if anyone could help me out, I need to clean up this controller as the resulting code to simply update an items quantity if it already exists seems way too complex. class LineItemsController < ApplicationController def create @product = Product.find(params[:product_id]) if LineItem.exists?(:cart_id => current_cart.id) item = LineItem.find(:first, :conditions => [ "cart_id = #{@current_cart.id}"]) LineItem.update(item.id, :quantity => item.quantity + 1) else @line_item = LineItem.create!(:cart => current_cart, :product => @product, :quantity => 1, :unit_price => @product.price) flash[:notice] = "Added #{@product.name} to cart." end redirect_to root_url end end ` As always any help is much appreciated, the code should be fairly self explanatory, thanks :) PS posted it here as well as it looks a bit funny on here http://pastie.org/994059

  • Enhanced Podcasts and MPMoviePlayerViewController

    - by Ben Robinson
    Hi, This is a bit of an odd/specific one - possibly a bug? I'm using MPMoviePlayerViewController to play a variety of files, including Enhanced Podcasts - these are audio files, but with a slideshow of images, often created using GarageBand. Until (i think) iOS 3.2 they weren't supported at all, now they are and play fine in the iPod app, but in my app the slideshow doesn't start, the full screen movie player opens, and the audio begins, but all I see is the QuickTime logo. If I scrub the track the pictures appear - and will continue to play correctly - but I see nothing if I don't scrub! Any ideas?? On a related note, these files also include a small rectangluar button containing an (i) button on the right hand side - anybody know what it is or should do?! It does nothing for me!

  • ApnsPHP in server mode (ApnsPHP_Push_Server)

    - by Kukosk
    Hi, Im using ApnsPHP for push notifications on my server, but it's a little bit slow when you have to send a lot of notifications, so i decided to Run it in the server mode. I just want it to run in cron every 1 hour, check if there are some notifications to be sent, and if yes, run it in 5 processes to be faster. I'm sending updates to my users once a day depending on the timezone they set. So i have to run it every hour, and send messages to timezones that actually have 12:00 PM. Is there any way to do this? I know there is a demonstration but i just have no clue about how to do it. A simple sample will really help. Thank you millions!!

  • Understanding pattern matching with cons operator

    - by Mathias
    In "Programming F#" I came across a pattern-matching like this one (I simplified a bit): let rec len list = match list with | [] -> 0 | [_] -> 1 | head :: tail -> 1 + len tail;; Practically, I understand that the last match recognizes the head and tail of the list. Conceptually, I don't get why it works. As far as I understand, :: is the cons operator, which appends a value in head position of a list, but it doesn't look to me like it is being used as an operator here. Should I understand this as a "special syntax" for lists, where :: is interpreted as an operator or a "match pattern" depending on context? Or can the same idea be extended for types other than lists, with other operators?

  • How to migrate existing udp application to raw sockets

    - by osgx
    Hello Is there a tutorial for migration from plain udp sockets (linux, C99/C++, recv syscall is used) to the raw sockets? According to http://aschauf.landshut.org/fh/linux/udp_vs_raw/ch03s04.html raw socket is much faster than udp. Application is client-server. client is proprietary and must use exactly same procotol as it was with udp server. But server can be a bit faster with raw sockets. What parts of udp I must to implement in server? Is there a "quick migration" libraries?

  • Prevent Visual Studio Web Test from changing request details

    - by keithwarren7
    I have a service that accepts Xmla queries for Analysis services, often times those queries themselves will have a string that contains a fragment that looks something like {{[Time].[Year].[All]}} Recording these requests works fine but when I try to re-run the test I get an error from the test runner... Request failed: Exception occurred: There is no context parameter with the name ' [Time].[Year].[All]' in the WebTestContext This was confusing for some time but when I asked VS to generate a coded version of the test I was able to see the problem a bit better. VS searches for the '{{' and '}}' tokens and makes changes, considering those areas to refer to Context parameters, the code looks like this.Context["\n\t[Time].[Year].[All]"].ToString() Anyone know how to instruct Visual Studio to not perform this replacement operation? Or another way around this issue?

  • C++ defines for a 'better' Release mode build in VS

    - by darid
    I currently use the following preprocessor defines, and various optimization settings: WIN32_LEAN_AND_MEAN VC_EXTRALEAN NOMINMAX _CRT_SECURE_NO_WARNINGS _SCL_SECURE_NO_WARNINGS _SECURE_SCL=0 _HAS_ITERATOR_DEBUGGING=0 My question is what other things do fellow SOers use, add, define, in order to get a Release Mode build from VS C++ (2008,2010) to be as performant as possible? btw, I've tried PGO etc, it does help a bit but nothing that comes to parity, also I'm not using streams, the C++ i'm talking about its more like C but making use of templates and STL algorithms. As it stands now very simple code segments flop when compared to what GCC produces on say an equivalent x86 machine running linux (2.6+ kernel) using 02. Side-Note: I believe a lot of the issues relate directly to the STL version (Dinkum) provided by MS. Could people please elaborate on experiences using STLPort etc with VS C++.

  • Delay after pressing a button

    - by KrLx_roller
    After I press a button, Android parse a JSON file and pick the info it needs. Until yesterday, I was using an external library created by a user and it worked perfectly. But now, I don't want to depend on him, so I've searching info about Google's GSON. I've implemented this library with no problem, but now, after pressing the button that opens a new activity there's a delay. This delay is due to the connection and parsing that are done before the activity shows. How can I force the app to wait the Internet connection until de Activity is shown? It's a lil bit uncomfortable because after pressing the button, it seems that the app has frozen, but after all data is loaded, the new activity appears. Thank you in advance!

  • Obfuscate strings in Python

    - by Caedis
    I have a password string that must be passed to a method. Everything works fine but I don't feel comfortable storing the password in clear text. Is there a way to obfuscate the string or to truly encrypt it? I'm aware that obfuscation can be reverse engineered, but I think I should at least try to cover up the password a bit. At the very least it wont be visible to a indexing program, or a stray eye giving a quick look at my code. I am aware of pyobfuscate but I don't want the whole program obfuscated, just one string and possibly the whole line itself where the variable is defined. Target platform is GNU Linux Generic (If that makes a difference)

  • regular expressions: love or hate or alternatives?

    - by yamspog
    While I can see the value and usefulness of regular expressions, I also find that they are extremely complicated and difficult to create and debug. I am often at the point where I find their usefulness is offset by the difficulty in creating expressions. I am a bit astonished by the fact that there is nothing quite like them and that there hasn't been an effort to recreate them use a more verbose or less arcane syntax. so, are regular expressions here to stay? are there alternatives that are gaining traction? do other people just ignore them and write hundreds of lines of string compare functions?

  • Injecting an XML fragment into the current document from an external file

    - by makenai
    I'm currently parsing an XML file using REXML and trying to come up with a way of inserting an XML fragment from an internal file. Currently, I'm using some logic like the following: doc.elements.each('//include') do |element| handleInclude( element ) end def handleInclude( element ) if filename = element.attributes['file'] data = File.open( filename ).read doc = REXML::Document.new( data ) element.parent.replace_child( element, doc ) end end Where my XML looks like the following: <include file="test.xml" /> But this seems a little bit clunky, and I'm worried that REXML might not always parse XML fragments correctly due to absence of a proper root node in some cases. Is there a better way of doing this? Concern #2: REXML seems not to pick up my changes after I replace elements. For example, after making a change: doc.elements.each('rootNode/*') do |element| end ..picks up neither the original element I replaced, nor the one I replaced it with. Is there some trick to getting REXML to rescan its' tree?

  • Transportation Web App - utilizing google or bing map api

    - by BillS
    I am working on a transportation web app and I am having a bit of a problem. First, I want to be able to define a shipping corridor, say like I-95 between Baltimore MD and Richmond VA. And store what parameters I need to define this route. Users will then use a web interface and can select various routes, in this case, I-95. Vendors will be posting constantly changing pickup locations in the application database which have a shelf life of about 2 days. Some of these locations maybe along this route. I am storing the LAT and LONG for the specific location right now. If any of these points ARE along or within 2 mile of the route (just off the highway basically - the ideal check would based on an actual highway exit but at this point anything would work), I want them to show up in my search results. Any ideas or suggestions?

  • Getting sign of an integer in Assembly

    - by Sagekilla
    Hi all, I'm writing some assembly for a project using MASM (32-bit), and I was wondering what would be the easiest way to do this: int delta = A - B; int value = floor((delta + sign(delta)) / 2); Which is basically the following mapping: For 1 < A < 9, and B = 5: A = [1, 2] -> -2 A = [3, 4] -> -1 A = [5] -> 0 A = [6, 7] -> +1 A = [8, 9] -> +1 Any help is much appreciated!

  • Mercurial - revert back to old version and continue from there

    - by Paolo
    I'm using mercurial locally for a project (it's the only repo there's no pushing/pulling to/from anywhere else). To date it's got a linear history. However, the current thing I'm working on I've now realised is a terrible approach and I want to go back to the version before I started it and implement it a different way. I'm a bit confused with the branch / revert / update -C commands in Mercurial. Basically I want to revert to version 38 (currently on 45) and have my next commits have 38 as a parent and carry on from there. I don't care if revisions 39-45 are lost for ever or end up in a dead-end branch of their own. Which command / set of commands do I need?

    Dear Gurus All you be agree with the value and worth of Performance Counters while developing and maintaining a server kind application I would like to know what is the best way to implement those, Specifically using C#? Usually performance counters have the following attributes They are shared global Writing requires locks to ensure Synchronization Reading Some times requires locks too.
