• Copying a foreign Subversion repository to keep under dependencies

  - by Jonathan Sternberg

  I want to keep dependencies for my project in our own repository, that way we have consistent libraries for the entire team to work with. For example, I want our project to use the Boost libraries. I've seen this done in the past with putting dependencies under a "vendor" or "dependencies" folder. But I still want to be able to update these dependencies. If a new feature appears in a library and we need it, I want to just be able to update that repository within our own repository. I don't want to have to recopy it and put it under version control again. I'd also like for us to have the ability to change dependencies if a small change is needed without stopping us from ever updating the library. I want the ability to do something like 'svn cp', then be able to 'svn merge' in the future. I just tried this with the boost trunk, but I'm not able to get any history using 'svn log' on the copy I made. How do I do this? What is usually done for large projects with dependencies?

• Upgrade .NET 1.1 WinForm/Service to what?

  - by Conor

  Hi Folks, We have a current WinForm/Windows Service running in .NET 1.1 out on various customer sites that is getting data from internal systems, transforming it and then calling a Web Service synchronously. This client app will no longer work in Vista or Windows 7 etc.. and its time to update!! I was looking for ideas on what I could do here, I didn't write the App and I have the Business team telling me they want the world but I need to be realistic :) Things the service must be able to do: - Handle multiple formats from internal system and transform to a schema SAP, ERP etc.. - Run silently and just work on customer sites (it does currently albeit .NET 1.1) - The Customers are unable to call our web service from their sites as they are not technical enough. - Upgrade it's self when updates occur (currently don't have this capability) Is there anything I can do here other than upgrade the service to run in .NET and add a few more transformation capabilities e..g they want the customer to be able to give us a flat file, an xml file, a csv and the service transforms it and calls the Web Service? I was hoping in this day and age we could use the Web, but automating this 100% rules it out in my eyes? I could be totally wrong!! Any help would be gratefully appreciated! Cheers. Conor

• CakePHP 1.26: Bug in 'Security' component?

  - by Steve

  Okay, for those of you who may have read this earlier, I've done a little research and completely revamped my question. I've been having a problem where my form requests get blackholed by the Security component, although everything works fine when the Security component is disabled. I've traced it down to a single line in a form: <?php echo $form->create('Audition');?> <fieldset> <legend><?php __('Edit Audition');?></legend> <?php echo $form->input('ensemble'); echo $form->input('position'); echo $form->input('aud_date'); // The following line works fine... echo $form->input('owner'); // ...but the following line blackholes when Security included // and the form is submitted: // echo $form->input('owner', array('disabled'=>'disabled'); ?> </fieldset> <?php echo $form->end('Submit');?> (I've commented out the offending line for clarity) I think I'm following the rules by using the form helper; as far as I can tell, this is a bug in the Security component, but I'm too much of a CakePHP n00b to know for sure. I'd love to get some feedback, and if it's a real bug, I'll submit it to the CakePHP team. I'd also love to know if I'm just being dumb and missing something obvious here.

• Regular input in ASP.NET

  - by coffeeaddict

  Here's an example of a regular standard HTML input for my radiobuttonlist: <label><input type="radio" name="rbRSelectionGroup" checked value="0" />None</label> <asp:Repeater ID="rptRsOptions" runat="server"> <ItemTemplate> <div> <label><input type="radio" name="rbRSelectionGroup" value='<%# ((RItem)Container.DataItem).Id %>' /><%# ((RItem)Container.DataItem).Name %></label> </div> </ItemTemplate> </asp:Repeater> I removed some stuff for this thread, one being I put an r for some name that I do not want to expose here so just an fyi. Now, I would assume that this would or should happen: Page loads the first time, the None radio button is checked / defaulted I go and select a different radiobutton in this radiobutton list I do an F5 refresh in my browser The None radio button is pre-selected again after it has come back from the refresh but #4 is not happening. It's retaining the radiobutton that I selected in #2 and I don't know why. I mean in regular HTML it's stateless. So what could be holding this value? I want this to act like a normal input button. I know the question of "why not use an ASP.NET control" will come up. Well there are 2 reasons: The stupid radiobuttonlist bug that everyone knows about I just want to brush up more on standard input tags We are not moving to MVC so this is as close as I'll get and it's ok, because the rest of the team is on par with having mixed ASP.NET controls with standard HTML controls in our pages Anyway my main question here is I'm surprised that it's retaining the change in selection after postback.

• Lucene setboost doesn't work

  - by Keven

  Hi all, OUr team just upgrade lucene from 2.3 to 3.0 and we are confused about the setboost and getboost of document. What we want is just set a boost for each document when add them into index, then when search it the documents in the response should have different order according to the boost I set. But it seems the order is not changed at all, even the boost of each document in the search response is still 1.0. Could some one give me some hit? Following is our code: String[] a = new String[] { "schindler", "spielberg", "shawshank", "solace", "sorcerer", "stone", "soap", "salesman", "save" }; List strings = Arrays.asList(a); AutoCompleteIndex index = new Index(); IndexWriter writer = new IndexWriter(index.getDirectory(), AnalyzerFactory.createAnalyzer("en_US"), true, MaxFieldLength.LIMITED); float i = 1f; for (String string : strings) { Document doc = new Document(); Field f = new Field(AutoCompleteIndexFactory.QUERYTEXTFIELD, string, Field.Store.YES, Field.Index.NOT_ANALYZED); doc.setBoost(i); doc.add(f); writer.addDocument(doc); i += 2f; } writer.close(); IndexReader reader2 = IndexReader.open(index.getDirectory()); for (int j = 0; j < reader2.maxDoc(); j++) { if (reader2.isDeleted(j)) { continue; } Document doc = reader2.document(j); Field f = doc.getField(AutoCompleteIndexFactory.QUERYTEXTFIELD); System.out.println(f.stringValue() + ":" + f.getBoost() + ", docBoost:" + doc.getBoost()); doc.setBoost(j); }

• Is there any reason to use C instead of C++ for embedded development?

  - by Piotr Czapla

  Question I have two compilers on my hardware C++ and C89 I'm thinking about using C++ with classes but without polymorphism (to avoid vtables). The main reasons I’d like to use C++ are: I prefer to use “inline” functions instead of macro definitions. I’d like to use namespaces as I prefixes clutter the code. I see C++ a bit type safer mainly because of templates, and verbose casting. I really like overloaded functions and constructors (used for automatic casting). Do you see any reason to stick with C89 when developing for very limited hardware (4kb of RAM)? Conclusion Thank you for your answers, they were really helpful! I though the subject through and I will stick with C mainly because: It is easier to predict actual code in C and this is really important if you have only 4kb of ram. My team consists of C developers mainly so advance features of C++ won't be frequently used. I've found a way to inline functions in my C compiler (C89). It is hard to accept one answer as you provided so many good answers. Unfortunately I can't create a wiki and accept it so I will choose one answer that made me think most.

• Why would ASP.NET MVC use session state?

  - by ray247

  Recommended by the ASP.NET team to use cache instead of session, we stopped using session from working with the WebForm model the last few years. So we normally have the session turned off in the web.config <sessionState mode="Off" /> But, now when I'm testing out a ASP.NET MVC application with this setting it throw an error in class SessionStateTempDataProvider inside the mvc framework, it asked me to turn on session state, I did and it worked. Looking at the source it uses session Dictionary<string, object> tempDataDictionary = httpContext.Session[TempDataSessionStateKey] as Dictionary<string, object>; // line 20 in SessionStateTempDataProvider.cs So, why would they use session here? What am I missing? Thanks, Ray. ======================================================== Edit Sorry didn't mean for this post to debate on session vs. cache, but rather in the context of the ASP.NET MVC, I was just wondering why session is used here. In this Scott Watermasysk blog post he mentioned on turning off session too as a good practice, so I'm just wondering do I have to turn it on to use MVC from here on?

• Internet Explorer randomly drops sessions between pages in cakePHP

  - by Emerson Taymor

  Hello everyone, I've come across an extremely unusual bug that my team has literally no idea how to solve. Doing some research, I found some similar solutions that I thought would work, but alas did not. Here is my situation, let me know if I can provide additional insight to help solve the problem. The first step is that someone chooses a country via a flash map. Flash passes this region name (as well as a date) through the URL, which we then convert to a session. The next page contains no Flash and doesn't display the selected region, but it does hold on to it for further down the process. Everything works perfectly in Safari and Firefox; however, in IE sometimes unexpected results occur. Frequently (but not always), the session is dropped completely and no sessions are stored between the first and 2nd pages. Here are the steps that I have taken thus far, unsuccessfully: 1. Changed Security from Medium - Low 2. Changed CheckUserAgent from True - False 3. Changed storing of sessions from PHP - Database Some additional information that may be useful: I have tried printing out the session data in Debug (debug($_SESSION) on my view file and debug set to 2 in config). In Internet Explorer everything prints out as expected EXCEPT when the region and date don't get set. For example: If the region and date don't get set NOTHING is printed out for debug. I don't get the session details at the top, and I don't get the normal dump of calls at the bottom of the page either. I am not using redirection on these pages. Please let me know if you have ANY idea of what is causing this or any solutions. I am beyond frustrated and have tried as much as I can to solve this. Thanks!

• What to use for version control with Visual Studio 2008 for inhouse projects?

  - by Boog

  We want to put a number of our in-house projects under version control. Our projects are C# .NET applications and assemblies. We originally decided to go Microsoft all the way (as is the norm around here), and tried installing Visual Studio Team Foundation Server. To say the least, it was way more trouble of trying to get a successful install than it's worth, and I'm afraid we don't have a entire server to dedicate to TFS itself, as the installer seems to insist. We also considered a generic solution like Subversion or CVS, or possibly some kind of free online hosting that doesn't make our source publicly available under some license like Google Code appears to. Does anyone have any suggestions for us that would best fit our in-house MS environment? We'd also get some benefit out of some kind of project management tools if they were nicely integrated in to the solution, but this would only be a perk. I should also mention that we haven't entirely ruled out TFS, but it's looking like a pain, so anything you guys have to say for or against it would be helpful.

• What are the common compliance standards for software products?

  - by Jay

  This is a very generic question about software products. I would like to know what compliance standards are applicable to any software product. I know that question gives away nothing. So, here is an example to what I am referring to. CiSecurity Security Certification/Compliance lists out products ceritified by them to be compliant to the standards published at their website, i.e, cisecurity.org. Compliance could be as simple as answering a questionnaire for your product and approved by a thirdparty like cisecurity or it could apply to your whole organization, for instance, PCI-DSS compliance. I would be very interested in knowing the standards that products you know/designed/created, comply to. To give you the context behind this question: I am the developer of a data-masking tool. The said tool helps mask onscreen html text in a banking web application using filters. So, for instance, if the bank application lists out user information with ssn, my product when integrated with the banking product, automatically identifies ssn pattern and masks it into a pre-defined format.So, I have my product marketing team wanting more buzz words like compliance to be able to sell it to more banking clients. Hence, understanding "compliances that apply to products" is a key research item for me at this point. By which I meant, security compliances. Appreciate all your help and suggestions.

• How can I set a Java applet transparency to show contents behind it?

  - by yuri

  I've got a web page with an applet inside. This applet is a drop target on a drag and drop action from the OS, I simply take an image from a folder, drag it on the applet and something happens. I give this webpage to a graphic designer and he ask to if he can put an image behind the java applet so he can simulate to change the background using CSS (it is a skinned app and graphic design can change during execution). Practically i supposed to do: <div> <applet width="50" height="50" /> </div> with this CSS: div { width:50px; height:50px; background-image: url(image.jpg) center center no-repeat; } But it doesn't work (background is opaque). It is possible to set transparency to the applet without loosing drag and drop capabilities ? I'm searching something similar to flash wmode parameter. Better solutions implies only changes on the CSS/HTML without recompiling java class so the designing team can change the page structure without changing the Java.

• Replacement for Hamachi for SVN access

  - by Piers

  My company has been using Hamachi to access our SVN repository for a number of years. We are a small yet widely distributed development team with each programmer in a different country working from home. The server is hosted by a non-techie in our central office. Hamachi is useful here since it has a GUI and supports remote management. This system worked well for a while, but recently I have moved to a country with poor internet speeds. Hamachi will no longer connect 99% of the time - instead I get a "Probing..." message that doesn't resolve. It's certain to be a latency issue, as the same laptop will connect without problems when I cross the border and connect using a different ISP with better speeds. So I really need to replace Hamachi with some other VPN/protocol that handles latency better. The techie managing the repository is not comfortable installing and configuring Apache or IIS, so it looks like HTTP is out. I tried to convince my boss to go for a web hosting company, but he doesn't trust a 3rd party with our source. Any other recommended options / experiences out there for accessing our SVN repos that would be as simple as Hamachi for setup; but be more tolerant of network latency issues?

• C++ & proper TDD

  - by Kotti

  Hi! I recently tried developing a small-sized project in C# and during the whole project our team used the Test-Driven-Development (TDD) technique (xunit, moq). I really think this was awesome, because (when paired with C#) this approach allowed to relax when coding, relax when projecting and relax when refactoring. I suspect that all this TDD-stuff actually simplifies the coding process and, well, it allowed (eventually, for me) to get the same result with fewer brain cells working. Right after that I tried using TDD paired with C++ (I used Google Test and Google Mock libraries), and, I don't know why but I actually think that TDD here was a step back in terms of rapid application development. I had some moments when I had to spend huge amounts of time thinking of my tests, building proper mocks, rebuilding them and swearing at my monitor. And, well, I obviously can't ask something like "what I did wrong?" or "what was wrong in my approach?", because I don't know what to describe. But if there are any people who are used to TDD in C++ (and, probably C#) too, could you please advise me how to do this properly. Framework recommendations, architecture approaches, plain coding advices - if you are experienced in TDD & C++, please respond.

• Performance of VIEW vs. SQL statement

  - by Matt W.

  I have a query that goes something like the following: select <field list> from <table list> where <join conditions> and <condition list> and PrimaryKey in (select PrimaryKey from <table list> where <join list> and <condition list>) and PrimaryKey not in (select PrimaryKey from <table list> where <join list> and <condition list>) The sub-select queries both have multiple sub-select queries of their own that I'm not showing so as not to clutter the statement. One of the developers on my team thinks a view would be better. I disagree in that the SQL statement uses variables passed in by the program (based on the user's login Id). Are there any hard and fast rules on when a view should be used vs. using a SQL statement? What kind of performance gain issues are there in running SQL statements on their own against regular tables vs. against views. (Note that all the joins / where conditions are against indexed columns, so that shouldn't be an issue.) EDIT for clarification... Here's the query I'm working with: select obj_id from object where obj_id in( (select distinct(sec_id) from security where sec_type_id = 494 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) and sec_obj_id in ( select obj_id from object where obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) ) ) ) or (obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) and obj_id not in (select sec_obj_id from security where sec_type_id = 494) )

• Not able to connect to TFS Server from TFS Proxy

  - by GV India

  In our office we have setup TFS for project development. The TFS Server is WIN 2003 server SP2 with VSTFS 2008 and is running fine. Now we need to setup a TFS Proxy server on client site for client to access. Before going for the client setup, I wanted to build and test proxy in our office on a dummy server (will call it Proxy server hereon) by keeping it on a different domain. OS configuration of the Proxy server is the same as TFS server. I have installed and configured TFS proxy on Proxy server to connect to TFS Server. Also we have built trust between the two different domains to enable communication. Now problem is that I am not able to at all connect to TFS server. I am trying to connect from Internet Explorer of proxy server using proxy service account. It gives me error: The page cannot be displayed. HTTP 500 - Internal server error. The page I was browsing was http://tfs:8080/VersionControl/v1.0/ProxyStatistics.asmx. I think I have done all the required steps correctly to configure proxy as described in MSDN and also TFS installation guide. Here Proxy service account is a member of ‘Team Foundation Valid Users’ group. I am able to connect to TFS Server (specifying port) using Telnet from command prompt on proxy server as suggested by few sites. The TFS server web sites have been configured to use Integration Windows Authentication. Event Logs on both the servers are also not giving any error. Overall I’m not able to get it done. Any ideas on what might be the problem???

• Is ADO.NET Entity framework database schema update possible?

  - by fyasar

  I'm working on proof of concept application like crm and i need your some advice. My application's data layer completely dynamic and run onto EF 3.5. When the user update the entity, change relation or add new column to the database, first i'm planning make for these with custom classes. After I rebuild my database model layer with new changes during the application runtime. And my model layer tie with tightly coupled to my project for easy reflecting model layer changes (It connected to my project via interfaces and loading onto to application domain in the runtime). I need to create dynamic entities, create entity relations and modify them during the runtime after that i need to create change database script for updating database schema. I know ADO.NET team says "we will be able to provide this property in EF 4.0", but i don't need to wait for them. How can i update database changes during the runtime via EF 3.5 ? For example, i need to create new entity or need to change some entity schema, add new properties or change property types after than how can apply these changes on the physical database schema ? Any ideas ?

• Where can a self-teacher learn general good programming habits and conventions?

  - by lucid

  A few mistakes and general childishness in early adulthood have left me in a situation where I work a menial job, with no possibility (in the near future) of attending school. I aspire to one day work in the programming field (gaming specifically), after proving myself on the indie end of things. I've gotten very confident in C++, java, and python, and I find I'm able to solve any problem I want either from previous experience, or from scouring the web for help. The solutions work, and with each attempt they become more readable, maintainable, and extensible. But this is because I'm learning from mistakes and bad programming and design habits I feel I might have avoided with actual schooling. General tips like: "if it's hard to read or getting long, or you're writing it twice, it should be in one or more functions." or "design all your classes before you start coding, so you don't have to rewrite classes later when you discover an unforeseen dependency" Is there a good book or website for learning general good programming practices and design habits? Also, naming and format conventions. I realize sometimes development houses have their own conventions, but things like "Classes in python usually have the first letter of each word capitalized". I'd like to be able to show some source code to a potential employer, and be prepared when for what's expected on a team. Is there some central database of naming and formatting conventions somewhere? Also, feel free to give any thoughts on whether or not the self-teach, garner some indie sales, use them as your resume' route is realistic

• How to detect how many time the users have click the button...

  - by Jerry

  Hello guys. Just want to know if there is a way to detect how many times a user has clicked a button by using Jquery. My main application has a button that can add input fields depend on the users. He/She can adds as many input fields as they need. When they submit the form, The add page will add the data to my database. My current idea is to create a hidden input field and set the value to zero. Every time a user clicks the button, jquery would update the attribute of the hidden input field value. Then the "add page" can detect the loop time. See the example below. I just want to know if there are better practices to do this. Thanks for the helps. main page <form method='post' action='add.php'> //omit <input type="hidden" id="add" name="add" value="0"/> <input type="button" id="addMatch" value="Add a match"/> //omit </form> jquery $(document).ready(function(){ var a =0; $("#addMatch").live('click', function(){ $('#table').append("<input name='match"+a+"Name' />") //the input field will append //as many as the user wants. a++; $('#add').attr('name', 'a'); //pass the a value to hidden input field return false; }); Add Page $a=$_POST['a']; // for($k=0;$k<$a;$k++){ //get all matchName input field $matchName=$_POST['match'.$k.'Name']; //insert the match $updateQuery=mysql_query("INSERT INTO game (team) values('$matchName')",$connection); if(!$updateQuery){ DIE('mysql Error:'+mysql_error()); }

• EMF ecore and xsd out of sync, how to resolve ?

  - by SeB

  Hi there, My application is using a model base on an xsd that have been converted to an ecore before generation of the java classes. One of my team member modified the .ecore metamodel in a previous version ,one attribute that used to be generated. He modified the attribute name but not the Extended MetaData specifying the element name used for xml persistance. <eStructuralFeatures xsi:type="ecore:EReference" name="javaDocsAndUserApi" upperBound="-1" eType="#//JavaDocsAndUserApi" containment="true" resolveProxies="false"> <eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData"> <details key="kind" value="element"/> <details key="name" value="docsAndUserApi"/> </eAnnotations> </eStructuralFeatures> so we have an attribute name which is javaDocsAndUserApi and the persisted element named docsAndUserApi, and of course if I create change the attribute in the xsd to be named javaDocsAndUserApi, the ecore transformation will generate a metadata name javaDocsAndUserApi as well, which will break compatibility with previously persisted models. I have looked at xsd authoring guide to find an ecore:som_attribute that would allow me to specify which key to use in the xsd to force the metadata to be named docsAndUserApi during the xsd to ecore transformation but did not find anything. Does anybody have an idea to help me? Thank you.

• Mercurial CLI is slow in C#?

  - by pATCheS

  I'm writing a utility in C# that will make managing multiple Mercurial repositories easier for the way my team is using it. However, it seems that there is always about a 300 to 400 millisecond delay before I get anything back from hg.exe. I'm using the code below to run hg.exe and hgtk.exe (TortoiseHg's GUI). The code currently includes a Stopwatch and some variables for timing purposes. The delay is roughly the same on multiple runs within the same session. I have also tried specifying the exact path of hg.exe, and got the same result. static string RunCommand(string executable, string path, string arguments) { var psi = new ProcessStartInfo() { FileName = executable, Arguments = arguments, WorkingDirectory = path, UseShellExecute = false, RedirectStandardError = true, RedirectStandardInput = true, RedirectStandardOutput = true, WindowStyle = ProcessWindowStyle.Maximized, CreateNoWindow = true }; var sbOut = new StringBuilder(); var sbErr = new StringBuilder(); var sw = new Stopwatch(); sw.Start(); var process = Process.Start(psi); TimeSpan firstRead = TimeSpan.Zero; process.OutputDataReceived += (s, e) => { if (firstRead == TimeSpan.Zero) { firstRead = sw.Elapsed; } sbOut.Append(e.Data); }; process.ErrorDataReceived += (s, e) => sbErr.Append(e.Data); process.BeginOutputReadLine(); process.BeginErrorReadLine(); var eventsStarted = sw.Elapsed; process.WaitForExit(); var processExited = sw.Elapsed; sw.Reset(); if (process.ExitCode != 0 || sbErr.Length > 0) { Error.Mercurial(process.ExitCode, sbOut.ToString(), sbErr.ToString()); } return sbOut.ToString(); } Any ideas on how I can speed things up? As it is, I'm going to have to do a lot of caching in addition to threading to keep the UI snappy.

• How do repos (SVN, GIT) work?

  I read SO nearly everyday and mostly there is a thread about source control. I have a few questions. I am going to use SVN as example. 1) There is a team (small, large dosnt matter). In the morning everyone checks out the code to start working. At noon Person A commits, while person B still works on it. What happens when person B commits? how will person B know that there is an updated file? 2) I am assuming the answer to the first question is "run an update command which tells you", ok so person B finds out that the file they have been working on all morning in changed. When they see the udpated file, it seems like person A has REWRITTEN the file for better performance. What does person B do? Seems like there whole day was a waste of time. Or if they commit their version then its a waste of person A's time? 3) What are branches? thanks, and if anyone knows a laymen terms pdf or something that explains it that would be awesome.

• How do I manage dependencies for automated builds on my build server?

  - by Tom Pickles

  I'm trying to implement continuous integration into our day to day workings. In our team, we're moving from just building our code in Visual Studio on our workstations and deploying, to using MSBuild.exe and automating on our build server (which is Jenkins) without the use of Visual Studio. We have external dependencies to references such as Automap in our projects. Because the automap (for example) dll isn't on the build server, the msbuild execution fails, for obvious reasons. There are other dll's which I need to be part of the build, I'm just using automap as an example. So what's the best way to get any dependencies onto the build server as part of the automated build? I've seen references to using a 'lib' folder, but I don't really understand where I should be putting it (in my project, filesystem, SVN ...?), and how the build server will get to it. I've also read that NuGet can do something with dependencies, but my build server isn't connected to the internet, and I don't understand how I can get my build to pull a NuGet package I may have created, and how it works together. Edit: I'm using subversion and we cannot use TeamCity as we would have to buy it and there's zero chance of funding.

• Methods to Analyze Sell Orders (in a video game)

  - by Travis

  I'm building a market manager for EVE, but this problem should be solvable without any prior knowledge of the game. Basically, sell orders in EVE look like this: All I'm really concerned with is picking a good price. The numbers the program would pick are sent out to our production team so they can buy the items to build things. Just like in a real market, the numbers we send off need to reflect the cheapest price that still offers a good quantity. Also, available quantities change over time, so we can't just pick the lowest listed price. For example, in the screencap above, we would set the sell price between 2,800.00 ISK and 3,000.00 ISK, even if only 500 units were needed. Even though the cheapest order would fit the quantity, it would probably quickly disappear. It would be better to set the price a tad higher so we don't underpay the production people. The Question: It's easy enough to figure prices out just by looking at the data, but I can't figure out how to have a program [java] do it. Different items sell with much less or more quantities (i.e. 3 or 300 or 3000 items) so the program has to be able to modify itself based on the offerings. I don't really want code as much as I do a way to think this through. Thanks in advance.
