  • Adding Boost Library to a C++ project in Windows Eclipse

    - by kingrichard2005
    I recently installed the Boost Library on Windows using the installer, I'm trying to link to the library in Eclipse but am not having any luck. I tried going through Project Properties - C/C++ Build - Settings - MinGW C++ Linker - Libraries and add the reference "boost_filesystem" according to this website: http://www.ferdychristant.com/blog//archive/DOMM-76JN6N , but I think that only applies to Unix variants. Everytime I compile I get the error: "cannot find -lboost_filesystem" . I've scoured the net, but cannot find a way to properly use Boost in Eclipse under a Windows platform. Any help or suggestions are appreciated.

  • DRYing Search Logic in Rails

    - by Kevin Sylvestre
    I am using search logic to filter results on company listing page. The user is able to specify any number of parameters using a variety of named URLs. For example: /location/mexico /sector/technology /sector/financial/location/argentina Results in the following respectively: params[:location] == 'mexico' params[:sector] == 'technology' params[:sector] == 'financial' and params[:location] == 'argentina' I am now trying to cleanup or 'DRY' my model code. Currently I have: def self.search(params) ... if params[:location] results = results.location_permalink_equals params[:location] if results results = Company.location_permalink_equals params[:location] unless results end if params[:sector] results = results.location_permalink_equals params[:sector] if results results = Company.location_permalink_equals params[:sector] unless results end ... end I don't like repeating the searchs. Any suggestions? Thanks.

  • How can I detect a debugger or other tool that might be analysing my software?

    - by Workshop Alex
    A very simple situation. I'm working on an application in Delphi 2007 which is often compiled as 'Release' but still runs under a debugger. And occasionally it will run under SilkTest too, for regression testing. While this is quite fun I want to do something special... I want to detect if my application is running within a debugger/regression-tester and if that's the case, I want the application to know which tool is used! (Thus, when the application crashes, I could report this information in it's error report.) Any suggestions, solutions?

  • C#: How do I get the path of the assembly the code is in?

    - by George Mauer
    Is there a way to get the path for the assembly in which the current code resides? I do not want the path of the calling assembly, just the one containing the code. Basically my unit test needs to read some xml test files which are located relative to the dll. I want the path to always resolve correctly regardless of whether the testing dll is run from TestDriven.NET, the MbUnit GUI or something else. Edit: People seem to be misunderstanding what I'm asking. My test library is located in say c:\projects\myapplication\daotests\bin\Debug\daotests.dll and I would like to get the "*c:\projects\myapplication\daotests\bin\Debug*" path. The three suggestions so far fail me when I run from the MbUnit Gui: Console.Out.Write(Environment.CurrentDirectory) gives c:\Program Files\MbUnit Console.Out.Write(System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location) gives C:\Documents and Settings\george\Local Settings\Temp\ ....\DaoTests.dll Console.Out.Write(System.Reflection.Assembly.GetExecutingAssembly().Location) gives the same as the previous

    Hello, I was thinking of making a commercial application to sell to customers to install on their servers but I wanted to do it with PHP & MySQL. what should i do to ensure that the source code (& Database) will not be opened nor copied. The most important thing is the code will be hosted on the customer server. And also how to ensure that the customer will not resell the web application (like copying the code & Db to other people) Thank you

  • What are some best practises and "rules of thumb" for creating database indexes?

    - by Ash
    I have an app, which cycles through a huge number of records in a database table and performs a number of SQL and .Net operations on records within that database (currently I am using Castle.ActiveRecord on PostgreSQL). I added some basic btree indexes on a couple of the feilds, and as you would expect, the peformance of the SQL operations increased substantially. Wanting to make the most of dbms performance I want to make some better educated choices about what I should index on all my projects. I understand that there is a detrement to performance when doing inserts (as the database needs to update the index, as well as the data), but what suggestions and best practices should I consider with creating database indexes? How do I best select the feilds/combination of fields for a set of database indexes (rules of thumb)? Also, how do I best select which index to use as a clustered index? And when it comes to the access method, under what conditions should I use a btree over a hash or a gist or a gin (what are they anyway?).

  • default webmail url workaround

    - by jan
    Hi, Is there a way or at least a workaround on masking default webmail urls or disabling access webmail urls so users will not be able to change their passwords? Website is PHP based and is using apache server under a shared hosting account. The thing is that http://domain.com/webmail will let users access the main panel where they can change their individual passwords. We do not need this. Most solutions point to changing httpd.conf which we are not allowed to change since this is on a shared hosting service. I'm looking for at least a workaround to this issue. How about disabling it through their browsers if my client is under a network server, this would be a decent workaround isn't it? or are there any more suggestions aside from this? Please help. This is my urgent issue. Thank you very much!

  • Web Performance testing using VS2010 "Testing a file download"

    - by cheedep
    Hi All, I am trying out the VS 2010 testing tools for the first time. And I tried recording a web performance test and my actions had a file download implemented as in the KB article here http://support.microsoft.com/kb/812406 by streaming chunks of 10000 bytes. However my test is failing at the download saying "The response stream has been closed". Please help me understand why it is happening this way also any suggestions how you would test such a file download. My main aim was to see how the download was performing for a load test with Intercontinental 350kbps connection on files of about 30-50 MB. Thanks.

  • GKSession sendDataToAllPeers including sender?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. If the device doing the sending is also a GKSessionModePeer, I would expect it to "fire" its receiveData: message as well since I'm sending to all peers. Should I call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would be calling sendDataToAllPeers: and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendDataToAllPeers: list so that it responds exactly the same as all connected peers?

  • Doubt about django model API

    - by Clash
    Hello guys! So, here is what I want to do. I have a model Staff, that has a foreign key to the User model. I also have a model Match that has a foreign key to the User model. I want to select how much Matches every Staff has. I don't know how to do that, so far I only got it working for the User model. From Staff, it will not allow to annonate Match. This is what is working right now User.objects.annotate(ammount=Count("match")).filter(Q(ammount__gt=0)).order_by("ammount") And this is what I wanted to do Staff.objects.annotate(ammount=Count("match")).filter(Q(ammount__gt=0)).order_by("ammount") And by the way, is there any way to filter the matches? I want to filter the matches by a certain column. Thanks a lot in advance!

  • Opencart not working

    - by user1588341
    I can go to http://www.sunnybrookfs.com/sstore/upload/ and it works awesome. But when I change the physical path in the basic settings for this website in the iis manager to the sstore/upload/ directory only text shows up. No images can be found or css style sheets. So basically www. sunnybrookfs. com/ goes to my xampp page, then I can access my OpenCart by going to http://www.sunnybrookfs.com/sstore/upload/. If I want www.sunnybrookfs.com to point to my store it does not work. Any suggestions? Thank you.

  • How can I break into the development business scene if I'm the new kid on the block?

    - by Sergio Tapia
    I'm about 1 semester short of graduating from college with my Systems Engineer degree. I've started my own software development company here in a country in South America last week, and so far I managed to land myself a nice account. I have to build a simple enough program that will take me 6-7weeks to complete and I'll charge 2000$. 40% up front and the rest on completion. While this is great and I'm really excited about my first project (Hell it's a landmark for any professional!), I'm already setting my eye on landing projects that will be visible for other companies to see. I've spoken with many people in my trade around town and it seems there are two companies that manage the big accounts with other small companies scrounging around for the scraps. How can I break this so called fellowship that is pretty much a monopoly here? Any and all suggestions will be massively appreciated.

  • SOA design principles with regards to database relationships

    - by Eitan
    If I were to extricate my current membership provider from my solution, i.e. as a dll and expose it as a web service with it's own db, how would I model the relationships with regards to SOA design. For example I have a table: USER id, name, lastname, username, password, role. and table PRODUCT id, name, price, createdate, userid the foreign key being userid to table user. How would I model the relationship and/or query the db. If I wanted to get all products that were uploaded today for example, before I would query: SELECT u.name, u.lastname, u.username, p.* FROM PRODUCT p INNER JOIN USER u ON p.userid = u.id WHERE createdate = '05/05/2010' Now that I don't have the table within the database how would I perform this query? Thanks.

  • Better way to clean this messy bool method

    - by Luís Custódio
    I'm reading Fowler Clean Code book and I think that my code is a little messy, I want some suggestions: I have a simple business requirement that is return the date of new execution of my Thread. I've two class fields: _hour and _day. If actual day is higher than my _day field I must return true, so I'll add a month to "executionDate" If the day is the same, but the actual hour is higher than _hour I should return true too. So I did this simple method: private bool ScheduledDateGreaterThanCurrentDate (DateTime dataAtual) { if (dateActual.Day > _day) { return true; } if (dateActual.Day == _day && dateActual.Hour > _hour) { return true; } if (dateActual.Day == _day && dateActual.Hour == _hour) if (dateActual.Minute>0 || dateActual.Second>0) return true; return false; } I'm programming with TDD, so I know that the return is correct, but this is bad maintain code right?

  • google search as an rss feed

    - by Jonathan
    Hi guys, Is there a way to have treat google serach results as an rss feed? For example say I worked for stackoverflow and wanted to montior how if the results from the following search url: http://www.google.com/search?hl=en&q=stackoverflow changes from day today. It would be cool if I could append &output=rss to the url and get back a feed like with google news. But that does not seem to be supported. Anyone have ideas? (Note I am programing with Ruby and Rails, if that matters) Thanks! Jonathan

  • Where can I find simple beta cdf implementation.

    - by Gacek
    I need to use beta distribution and inverse beta distribution in my project. There is quite good but complicated implementation in GSL, but I don't want to use such a big library only to get one function. I would like to either, implement it on my own or link some simple library. Do you know any sources that could help me? I'm looking for any books/articles about numerical approximation of beta PDF, libraries where it could be implemented. Any other suggestions would be also appreciated. Any programming language, but C++/C# preffered.

  • NHibernate Projections to retrieve a Collection?

    - by Simon Söderman
    I´m having some trouble retrieving a collection of strings in a projection: say that I have the following classes public class WorkSet { public Guid Id { get; set; } public string Title { get; set; } public ISet<string> PartTitles { get; protected set; } } public class Work { public Guid Id { get; set; } public WorkSet WorkSet { get; set; } //a bunch of other properties } I then have a list of Work ids I want to retrieve WorkSet.Title, WorkSet.PartTitles and Id for. My tought was to do something like this: var works = Session.CreateCriteria<Work>() .Add(Restrictions.In("Id", hitIds)) .CreateAlias("WorkSet", "WorkSet") .SetProjection( Projections.ProjectionList() .Add(Projections.Id()) .Add(Projections.Property("WorkSet.Title")) .Add(Projections.Property("WorkSet.PartTitles"))) .List(); The Id and Title loads up just fine, but the PartTitles returns null. Suggestions please!

  • XmlSerializer Performance Issue when Specifying XmlRootAttribute

    - by Dougc
    I'm currently having a really weird issue and I can't seem to figure out how to resolve it. I've got a fairly complex type which I'm trying to serialize using the XmlSerializer class. This actually functions fine and the type serializes properly, but seems to take a very long time in doing so; around 5 seconds depending on the data in the object. After a bit of profiling I've narrowed the issue down - bizarrely - to specifying an XmlRootAttribute when calling XmlSerializer.Serialize. I do this to change the name of a collection being serialized from ArrayOf to something a bit more meaningful. Once I remove the parameter the operation is almost instant! Any thoughts or suggestions would be excellent as I'm entirely stumped on this one!

  • Flex: Would a computational engine for a Connect-4 type game be too slow?

    - by Robusto
    OK, I was just fooling around in my spare time and have made this cool interface and game-playing code for a Connect-4 type game, written in Flex and playable by 2 human players in Flash. It accurately detects wins, etc. I'm smart enough to know that I've done the easy part. Before I dig into an AI for game play, I wanted to ask if this is the kind of thing that can really be handled computationally by a Flash plugin. It seems to me that for every turn up until the end there are 8 possible moves, 8 responses to each move, etc. So wouldn't a perfect engine have to be able to potentially see 8^8 moves (over 16 million), and a fairly good engine see up to a million? I don't know game coding so this is new to me. What's a reasonable move horizon for such a game to be able to see?

  • How to use the correct Google OpenID url to login to my site?

    - by Michael Mao
    Hello everyone: I am trying to implement OpenID as one preferred option to my next web app here The code is taken from this tutorial and works if I use my openID from myopenid.com However, I believe most people would just love to use their everyday email address as their openID, as far as I know, Google, Yahoo, and some other big players have already done this in their systems. My question is: how could I find the correct "url" to enter in the form to login? I used my Google OpenID account for StackOverflow and it works just fine. I try to copy my openID like this: www.google.com/accounts/o8/id?id=aitoawllano10bzdzp3ht0diffry0qt6_j2ls-m And paste it directly into my form, but it doesn't work. I also tried to remove the url parameter, but that won't do, either. Thanks a lot in advance for any tips and suggestions.

  • How much should I charge for Rails programming?

    - by Oskar Gantt
    I have been asked to quote an hourly rate for freelance programming for a Rails project. Although it would be my first paid project on Rails, I know the technology well from personal projects and have a decade of professional programming experience. This would be my first freelance project ever, so I have no idea how to find out what the going rate for my services should be. Obviously, if I quote a rate that is too high, they may choose someone else - too low and I may feel cheated later on. Any suggestions? Update: I am in NYC and the project is scheduled for 6 months to a year (but this seems unrealistic - I think it will be a multi-year project). I would develop on site (at a corporate location) with one other developer and the project would consist of about 200 custom-built pages initially. 10 hour days with weekends and additional overtime as required. The customer has given no information about how much they will pay - "a competitive rate" - they want me to start the discussion.
