  • Regex to exclude 1 word out of a regex code.

    - by Mech Software
    I need a regex expert to help out on this one. Examples I've found on here and the net I cant seem to get right. I'm using PHP and I have the following regex expression /([^a-zA-Z0-9])GC([A-Z0-9]+)/ This matches items like GCABCD GC123A, etc. What i need to do is EXCLUDE GCSTATS from this. So basically I want it to work just as it has, except, ignore GCSTATS in the regex.

  • Why doesn't this Ruby on Rails code work as I intend it to?

    - by Justin Meltzer
    So I attempted to build what I asked about in this question: Fix voting mechanism However, this solution doesn't work. A user can still vote however many times he or she wants. How could I fix this and/or refactor? def create @video = Video.find(params[:video_id]) @vote = @video.video_votes.new @vote.user = current_user if params[:type] == "up" @vote.value = 1 else @vote.value = -1 end if @previous_vote.nil? if @vote.save respond_to do |format| format.html { redirect_to @video } format.js end else respond_to do |format| format.html { redirect_to @video } format.js {render 'fail_create.js.erb'} end end elsif @previous_vote.value == params[:type] @previous_vote.destroy else @previous_vote.destroy if @vote.save respond_to do |format| format.html { redirect_to @video } format.js end else respond_to do |format| format.html { redirect_to @video } format.js {render 'fail_create.js.erb'} end end end @previous_vote = VideoVote.where(:video_id => params[:video_id], :user_id => current_user.id).first end

  • SEO - Problems possibly related to 301 Moved Permanently

    - by ILMV
    Right, here's the story: We have had a website for one of our brands now for many years, the site design was very bad and recently did a complete overhaul, mostly design, but also some of the backend code. The original site was using links such as this example.com/products/item/127 and thus I wanted to change them to be move user friendly, especially to include the product name, the same link now reads example.com/product/127/my-jucy-product/. Since our switch over we have seen our Google results take a beating (we were on the first page for our normal search terms, now we're nearer the 4th!). The other problem we're having is that the links to the old products haven't updated to the new links despite me coding a 301 redirect from old to new. The 301 is not being fired from .htaccess, but in our PHP framework. I had a look at how the site is being loaded from a old link that is still in Google and here's what firebug is reporting: GET <google link> 302 Found GET example.com/products/item/127 302 Found GET example.com/products/item/127 301 Moved Permanently GET example.com/product/127/my-jucy-product/ 302 Found So the Google link has a 302, good. But when the old link comes in our framework is returning a 302! It's only afterwards when it finally hits the right part of the framework does it 301, so here's my question: Is the reason our old links have not changed and our Google Ranking has significantly nose dived because Google is seeing a 302 before the 301? At the time I was reluctant to mess with our .htaccess because it had become pretty complicated and I was under some pretty intense time constraints, now I'm wondering whether this was an incorrect disicion and perhaps I should revisit it. Many thanks! Edit Bugger, just signed up to the Webmaster Tools and I'm getting redirect errors all over the place, hundreds of them! I think this is my problem.

  • How can I tell if a set of parens in perl code will act as grouping parens or form a list?

    - by Ryan Thompson
    In perl, parentheses are used for overriding precedence (as in most programming languages) as well as for creating lists. How can I tell if a particular pair of parens will be treated as a grouping construct or a one-element list? For example, I'm pretty sure this is a scalar and not a one-element list: (1 + 1) But what about more complex expressions? Is there an easy way to tell?

  • How should I handle pages that move to a new url with regards to search engines?

    - by Anders Juul
    Hi all, I have done some refactoring on a asp.net mvc application already deployed to a live web site. Among the refactoring was moving functionality to a new controller, causing some urls to change. Shortly after the various search engine robots start hammering the old urls. What is the right way to handle this in general? Ignore it? In time the SEs should find out that they get nothing but 400 from the old urls. Block old urls with robots.txt? Continue to catch the old urls, then redirect to new ones? Users navigating the site would never get the redirection as the urls are updated through-out the new version of the site. I see it as garbage code - unless it could be handled by some fancy routing? Other? As always, all comments welcome... Thanks, Anders, Denmark

  • Concatenation with Zero is not occurring properly in code?

    - by Vineet
    I was trying to reverse a number in PL/SQL. It's working fine, but when my number contains any 0, the output is unexpected. For example: 1234 output 4321 1000 output 1 1203 ouput 3021 10001 output 1 DECLARE r number(9); num number(9):=&p_num; BEGIN WHILE num>=1 LOOP IF mod(num,10)=0 THEN -- extracting last digit of a number . r:=r||0; --if end digit is 0 then concat r with 0 ELSE r:=r||mod(num,10);--if mod is not 0 then it would be last digit. END IF; num:=trunc(num/10);--Removing last digit from number END LOOP; dbms_output.put_line(r); END;

  • Can you change VS Win Forms designer code generation?

    - by Big Endian
    We implemented new standards, which call for our private members to have a leading underscore. Like so: private System.Windows.Forms.Label _label; Unfortunately VS will put out the default below when you drag a new label onto your form: private System.Windows.Forms.Label label1; Is there a way to change that to: private System.Windows.Forms.Label _label1; Cheers, Plamen

  • How to checkout a case sensitive SVN source code branch to a case insensitive system?

    - by gagneet
    I am working on a Macbook system , which is formatted as a case insensitive system. The issue is that, I need to check out a SVN branch which has some case sensitive files in it. Example: inbuilt-file.c InBuilt-File.c How do I checkout this branch when both the files are in the same folder? When I try and checkout, it gives me an error stating that an unversioned file of the name already exists.

  • Accessing the MSP and PSP registers of the Cortex-M3 in C/C++ code using Keil's µVision

    - by Captain NedD
    I need to access the MSP and PSP registers (the main and process stack registers) of the Cortex-M3 processor. I'm writing in C/C++. The µVision and associated compiler doesn't let you do inline assembly for this Thumb-2 only core (and I'm not sure that'd be such a good idea anyway). I need to do this so that I can extract the immediate value of an svc instruction regardless of whether it was executed while in thread or handler mode. Thanks,

  • Entity Framework 4.0: Why Would One Use the Code Generated EntityObjects Over POCO Objects?

    - by senfo
    Aside from faster development time (Visual Studio 2010 beta 2 has no T4 templates for building POCO entity objects that I'm aware of), are there any advantages to using the traditional EntityObject entities that Entity Framework creates, by default? If Microsoft delivers a T4 template for building POCO objects, I'm trying to figure out why anybody would want to use the traditional method.

  • null != null - any ideas on how to re-arrange the code or prevent this?

    - by Alex
    Currently debugging, and found an if-statement which for no (I thought...) reason gave me an NPE, obviously for a reason. Which seemed to be that the statement turned out to be if(false && (null != null || null != Color)). if(destination != null && (destination.getPiece() != null || destination.getPiece().getColour() != pieceColour)) - the if-statement Both destination can be null and piece can be. The getColour() method returns an attribute of type Color from piece, which must be null if the piece is null. The piece at destination has a different pieceColour attribute then the one in the if-statement. Specifically, how do I re-arrange (destination.getPiece() != null) ?

  • C# check age of db Item

    - by Jacob Huggart
    Hello All, I am using C# to send an email with an encrypted link. The encrypted portion of the link contains a time stamp that needs to be used to verify if the link is more than 48 hours old. How do I compare an old time to the current time and find out if the old time is more than 48 hours ago? This is what I have now: var hours = DateTime.Now.Ticks - data.DTM.Value.Ticks; //data.DTM = stored time stamp if (hours.CompareTo(48) > 1) //if link is more than 48 hours old, deny access. return View("LinkExpired"); } Comparing ticks seems like it's a very backwards way to do it and I know that the hours.CompareTo would have to be adjusted if I stick with comparing ticks. How can I just get a value for the number of hours that have passed?

  • How do I find a source code position from an address given by a crash in Window CE

    - by Shane MacLaughlin
    I have a Windows mobile 4.0 application, written using EVC++ 4.0 SP4 with MFC, that is exhibiting a random occasional crash in the field. e.g. Exception ox800000002 at 00112584. It does not happen under various emulators and simulators, hence is very difficult to trace using a debugger. The crash throws up and address and exception type. Given that I have the PDB is there any way to track this address to the source. I can't recompile using VC++ 8 as it doesn't support the mobile 4 SDK. My guess is that without a stack trace I'm not going to have much joy, as the chances are that the exception may not be in my source. Worth a try all the same. Edit As suggested, I have looked at the address in the context of the .MAP file for the program. This reveals the following Address Publics by Value Rva+Base Lib:Object 0001:00000000 ?GetUnduValue@@YANMM@Z 00011000 f 7Par.obj ' ' ' 0001:001124b8 ?OnLButtonUp@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@AAVCPoint@@AAI@Z 001234b8 f gxseldrg.obj 0001:001126d8 ?OnSelDragStart@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@KK@Z 001236d8 f gxseldrg.obj Which suggests the error occured during CGXGridUserDragSelectRangeImp::OnLButtonUp(), which seems a bit odd as I don't think there was a mouse / keyboard / screen button pressed at the time. Could be the stack got fragged before the crash got reported, and I'm wasting my time. I'll recompile with assembler output to try to isolate it to a given line, but don't hold out much hope :( Does the fact that the map file reports segmented addresses e.g. 0001:xxxxxxxxx and the crash report unsegmented addresses mean I have to carry out some computation to get the map address from the crash address?

  • Clever ways to better test GPS code using only the iPhone simulator?

    - by Patty
    I've been playing around with the iPhone SDK, using MapKit and Core Location. What are some of the tricks you can use to better test things... while still on the simulator (long before I have to try it out on my iPhone). Is there a way to use NSTimer and regularly get 'pretend' values for location, heading, speed, etc? The simulator only giving 1 location... and no movement... really limits its 'testing' usefulness.

  • What is the ambiguity in this piece of code?

    - by cambr
    #include <iostream> using namespace std; class A { public: void eat(){ cout<<"A";} }; class B: public A { public: void eat(){ cout<<"B";} }; class C: public A { public: void eat(){ cout<<"C";} }; class D: public B,C { public: void eat(){ cout<<"D";} }; int main(){ A *a = new D(); a->eat(); } I am not sure this is called diamond problem or not, but why doesn't this work? When I said, a->eat() (remember eat() is not virtual), there is only one possible eat() to call, that of A. Why then, do I get this error: 'A' is an ambiguous base of 'D'

  • How should I rewrite my code to make it amenable to unittesting?

    - by justin
    I've been trying to get started with unit-testing while working on a little cli program. My program basically parses the command line arguments and options, and decides which function to call. Each of the functions performs some operation on a database. So, for instance, I might have a create function: def create(self, opts, args): #I've left out the error handling. strtime = datetime.datetime.now().strftime("%D %H:%M") vals = (strtime, opts.message, opts.keywords, False) self.execute("insert into mytable values (?, ?, ?, ?)", vals) self.commit() Should my test case call this function, then execute the select sql to check that the row was entered? That sounds reasonable, but also makes the tests more difficult to maintain. Would you rewrite the function to return something and check for the return value? Thanks

  • What is the correct way to specify dimensions in DIP from Java code ?

    - by Pavel Lahoda
    Trying to digest docs about design Multiple resolutions (http://d.android.com/guide/practices/screens_support.html#dips-pels) I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment : "android:layout_width="10dip" But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this ? I figured that I have to use property density of DisplayMetrics class but is this a correct way ? May I relly that formula : pixels * DisplayMetrics.density = dip is always correct ? Will there be API in DIPs for Java ?

  • How does 64 bit code work on OS-X 10.5?

    - by philcolbourn
    I initially thought that 64 bit instructions would not work on OS-X 10.5. I wrote a little test program and compiled it with GCC -m64. I used long long for my 64 bit integers. The assembly instructions used look like they are 64 bit. eg. imultq and movq 8(%rbp),%rax. I seems to work. I am only using printf to display the 64 bit values using %lld. Is this the expected behaviour? Are there any gotcha's that would cause this to fail? Am I allowed to ask multiple questions in a question? Does this work on other OS's?
