  • Port a live system from App Engine Helper to App Engine Patch

    - by Alexander
    I am running a live system that is currently serving about 20K pages a day which is based on App Engine Helper (Python) with session support provided by AppEngine utilities. One problem that I have been having is that sessions are occasionally randomly logging out. I would like to try using the App Engine Patch, since it has "native" django session support, but I am worried that this is possibly going to be like doing a brain transplant. Specifically, current database models are all inhereted from BaseModel provided by the App Engine Helper. While, App Engine Patch does not have this inheritance. Does anyone know if it is possible to migrate a live system from App Engine Helper to App Engine Patch? If so, do you have any advice or warnings that I should heed, before attempting this transition? Thank you and kind regards Alex

  • Rails Full Engine using a Full Engine

    - by SirLenz0rlot
    I've got this full rails engine Foo with functionality X. I want to make another engine, engine Bar, that is pretty much the same, but override funcitonality x with y. (it basically does the same, but a few controller actions and views are differently implemented). (I might split this later in several mountable engines, but for now, this will be the setup: project Baz, using engine Bar, which uses engine Foo) I would like to know if there are any pitfalls. It doesn't seem like a pattern that is often used? Anybody else using this 'some sort of engine inheritance'?

  • Gendarme Rules Customisation

    - by Apogee
    Does anyone know the correct way to explicitly specify which rules Gendarme will use? Or which rules to exclude? I'm not having a lot of joy searching the Mono documentation for the answer. What I'm trying to do is to specify the rules one by one in the Gendarme rules.xml file like this: <rules include="AvoidAssemblyVersionMismatchRule" from="Gendarme.Rules.BadPractice.dll"/> Doing this, I'm hoping we can then switch off the rules we don't care about. The problem is, after specifying all the rules in this way, I'm getting a different number of defects detected compared with when I use the default method Gendarme provides, which is of the form: <rules include="*" from="Gendarme.Rules.BadPractice.dll"/> <rules include="*" from="OTHER DLL NAMES"/> Has anyone done this before? Or can anyone point me in the direction of some Gendarme rules usage documentation?

  • BizTalk Business Rules Engine - Repeating Elements Question

    - by Andrew Cripps
    Hello I'm trying to create what I think should be a relatively simple business rule to operate over repeating elements in an XML schema. Consider the following XML snippet (this is simplified with namespaces removed, for readability): <Root> <AllAccounts> <Account id="1" currentPayment="10.00" arrearsAmount="25.00"> <AllCustomers> <Customer id="20" primary="true" canSelfServe="false" /> <Customer id="21" primary="false" canSelfServe="false" /> </AllCustomers> </Account> <Account id="2" currentPayment="10.00" arrearsAmount="15.00"> <AllCustomers> <Customer id="30" primary="true" canSelfServe="false" /> <Customer id="31" primary="false" canSelfServe="false" /> </AllCustomers> </AllAccounts> </Root> What I want to do is to have two rules: Set /Root/AllAccounts/Account[x]/AllCustomers/Customer[primary='true']/canSelfServe = true IF arrearsAmount < currentPayment Set /Root/AllAccounts/Account[x]/AllCustoemrs/Customer[primary='true']/canSelfServer = false IF arrearsAmount = currentPayment Where [x] is 0...number of /Root/AllAccounts/Account records present in the XML. I've tried two simple rules for this, and each rule seems to fire x * x times, where x is the number of Account records in the XML. I only want each rule to fire once for each Account record. Any help greatly appreciated! Thanks Andrew

  • Using Google's App Engine as CDN for static files

    - by Saif Bechan
    I am planning on moving my static files to Google's App Engine. I was wondering if this is a good idea to do. I have read that is it possible that Google will cache your files on multiple locations, which is a good thing in my opinion. The setup should also be quite easy in eclipse with the GAE plugins. But i still have my doubts on the performance of this. Is the setup of App Engine optimized for serving static content. Now I have Nginx server my static content, will App Engine perform the same way. Are there any other ups or downs using this method?

  • Have Free website Hosting with Google App Engine

    - by mickthompson
    I'm reading about Google App Engine. I'm creating a bunch of simple dynamic websites in java. I'm considering to use Google App Engine and setup my clients' website on it. In this way I've only to register a domain www.myclietdomain.com and then point that to the GoogleAppEngine application... In this way I plan to avoid hosting costs. Infact I'm paying even for hosting few static html pages... Do you think that is possible to use Google App Engine for this scope?

  • StyleCop Custom Rules

    - by Aligned
    There are several blogs on how to do this (http://scottwhite.blogspot.com/2008/11/creating-custom-stylecop-rules-in-c.html, etc). I’ve found a few useful things to point out: Debugging is difficult, but here are the steps (thanks to Tintin’s answer). “One way: 1) Delete your custom rules 2) Open Visual Studio (for dev), open your custom rule solution 3) Build & Deploy custom rules (a PostBuild action to copy the rules into the StyleCop folder is handy) 4) Open Visual Studio (for test) 5) Use VS (dev) and Attach to process devenv.exe (the test VS instance), set breakpoints in the rules you want to debug 6) Use VS’ (test) and right-click on project, Run StyleCop 7) Debug” ~ it worked once, now I’m having problems getting it to work again ~ I also get the message “Cannot evaluate expression because the code of the current method is optimized.” when I try to look at properties. Looking at the source code of the StyleCop.CSharp.Rules.dll that comes with the install. I used JustDecompile from Telerik. Create one xml file and name it the same as the one cs file (CodingGuildelineRules.cs and CodingGuidelinRules.xml) Deploy: 1. Build in Visual Studio 2. Close Visual Studio (Style cop is running so you can’t override your dll without closing) 3. Copy the dll from the bin to the C: \Program Files (x86)\StyleCop 4.7\ 4. Open the settings file or re-open Visual Studio

  • fwbuilder/iptables manually scripted + autogenerated rules at startup?

    - by Jakobud
    Fedora 11 Our previous IT-guy setup iptable rules on our firewall in a way that is confusing me and he didn't document any of it. I was hoping someone could help me make some sense of it. The iptables service is obviously starting at startup, but the /etc/sysconfig/iptables file was untouched (default values). I found in /etc/rc.local he was doing this: # We have multiple ISP connections on our network. # The following is about 50+ rules to route incoming and outgoing # information. For example, certain internal hosts are specified here # to use ISP A connection while everyone else on the network uses # ISP B connection when access the internet. ip rule add from 99.99.99.99 table Whatever_0 ip rule add from 99.99.99.98 table Whatever_0 ip rule add from 99.99.99.97 table Whatever_0 ip rule add from 99.99.99.96 table Whatever_0 ip rule add from 99.99.99.95 table Whatever_0 ip rule add from 192.168.1.103 table ISB_A ip rule add from 192.168.1.105 table ISB_A ip route add 192.168.0.0/24 dev eth0 table ISB_B # etc... and then near the end of the file, AFTER all the ip rules he just declared, he has this: /root/fw/firewall-rules.fw He's executing the firewall rules file that was auto-generated by fwbuilder. Some questions Why is he declaring all these ip rules in rc.local instead of declaring them in fwbuilder like all the other rules? Any advantage or necessity to this? Or is this just a poorly organized way to implement firewall rules? Why is he declaring ip rules BEFORE executing the fwbuilder script? I would assume that one of the first things the fwbuilder script does it get rid of any existing rules before declaring all the new ones. Am I wrong about this? If that was the case, the fwbuilder script would basically just delete all the ip rules that were defined in rc.local. Does this make any sense? Why is he executing all this stuff at startup in rc.local instead of just using iptables-save to keep the firewall settings at /etc/sysconfig/iptables that will get implemented at runtime?

  • How to unit test business rules?

    - by Robert Lamb
    I need a unit test to make sure I am accumulating vacation hours properly. But vacation hours accumulate according to a business rule, if the rule changes, then the unit test breaks. Is this acceptable? Should I expose the rule through a method and then call that method from both my code and my test to ensure that the unit test isn't so fragile? My question is: What is the right way to unit test business rules that may change?

  • Rules regarding iPhone apps

    - by iphone newbie
    iphone dev has this rule for iphone developers Be certain that the items you offer for purchase do not contain, or relate to, pornography, hate speech, defamation, or gambling (simulated gambling is acceptable). But how come there are apps in the app store such as iBetMate, which, in fact, allows users to gamble? Is there a clause or something that I missed in Apple's rules?

  • Rules engine for Silverlight?

    - by frances1983
    At the moment I'm developing a web based application using Silverlight 3.0. For the business rules I'm looking for a rules engine that's both easy to use for me and my users, which will work with SL3. Is something like that available out of the box or will I need to roll my own? I've Googled and looked around the various code sites (Codeplex, Code Project etc), but didn't see anything that suits my needs. I did also have a good long look at NxBRE, but it's Rules syntax is too complex for 'dummy' users.

  • What Data structure for Reputation Rules in C# (like stackoverflow)

    - by optician
    I am currently building a system which will have entities that will have scores like reputation etc.. I will have a service that will check for certain rules having been triggered, and will perform certain logic if they are triggered. Previously I have used say an Enum for doing this when I have only had to store an id and a description. public enum ShoppingCratCalculation { PartialCalculation = 1, CompleteCalculation =2 } But in this situation I want to carry more information, such as the modification to reputation, all in one place. I'm essentially asking what data structure would be best suited to storing this information, for each rule in the system. 1. Description = string ("User forgot to write a review") 2. DB id = int (23) 3. Rep score modification = int (-5) Maybe a little class (Rule) with these as properties , and then just a list? Does anyone have any best practice suggestions for this kind of struct?

  • What are some good resources for creating a game engine in XNA?

    - by Glasser
    I'm currently a student game programmer working on an indie project. We have a team of eleven people (five programmers, four artists, and two audio designers) aboard, all working hard to help design this game. We've been meeting for months now and so far we have a pretty buffed out Game Design Document as well as much audio/visual concept art. Our programmers are itching to progress on our own end. Each person in our programming team is well versed in C++, but is very familiar with C#. We have enough experience and skill that we're confident that we will be successful with our game, and we're looking to build our own game engine in XNA as it seems like it would be worth our time and effort in the end. The game itself will be a 2D beat 'em up style game to be released over xbox live and the PC. It's play style will be similar to that of Castle Crashers or Scott Pilgrim vs The World. We want to design the game engine to allow us to better implement our assets into the game as well as to simplify the creation of design elements/mechanics. Currently between our programmers, we have books such as "XNA 4.0" and "Game Coding Complete, Third Edition," but we'd still like more information on both XNA and (especially) building a game engine from scratch. What are any other good books, websites, or resources we could use to further map out and program our game engine?

  • Custom Domain for Google App Engine and Google Apps

    - by Kevin
    I have set up and configured Google App Engine and Google Apps to use my custom domain with a cname 'www'. I have configured my DNS (via fasthosts.co.uk) with the cname and pointed it to ghs.google.com. I can access the website using the google app engine domain at capel-y-crwys.appspot.com but I can't access it via my custom domain www.capelycrwys.org.uk. I have allowed several days for propagation of the DNS etc. The really strange this is I can access the app via my custom domain when I use the web browser on my Android mobile phone. I can't access the app via my custom domain from my home internet connection, my work internet connection or a friends internet connection. I tried a few online web proxies and I can access the app via the custom domain. I posted this question on the google forums code.google.com/appengine/forum/?place=topic%2Fgoogle-appengine%2FfUP-G_0FKE4%2Fdiscussion and a commentor has said he could access the app via the custom domain. So why can't I access it direct via my home internet connection etc? I've tried loads of google searching and even found a similar sounding post here on serverfault serverfault.com/questions/208461/custom-domain-name-server-not-found-google-app-engine-and-google-apps but it doesn't have an answer that helps me.

  • getting a job in game industry as a developer, just knowing a game engine

    - by numerical25
    I recently enrolled at a community college for game developement. But I am skeptical about the circulum. I have no experience in the gaming industry so I wouldnt be able to tell rather its a good investment or not. So I am asking you. I dont want to get too much into detail of all the classes I am taking so I will try to be brief. By the time I graduate, I should have a understanding of how a game engine works. I will be working with the unreal engine to develop a Multiplayer game from scratch. So in the process of my final project, I will learn how to work within the unreal engine, Learn python and learn how to use it's API to connect to a remote server and build game mechanics. Overall I will also recieve a associates degree in game development. I learn c++ but not c. The director said he was trying to implement c in the program as well. What I notice is I will not learn how to build a 3d game engine from scratch. They do not teach any AI. I will not learn how to work with the graphics card using a graphic's api such as DirectX or OpenGL. I know building a game engine from scratch is a little complex, but at the same time the track is requireing me to take some advances math courses such a calculus and geotomtry 1 and 2. I also got to take a physic class. I just think thats a little much for just learning how to use the unreal engine but not actually build one or try to learn the anatomy of a game engine. Is this good enough to possibly land my a job in the insdustry. If I left anything out or was not detail, please feel free to ask more questions. Thanks Guys!!

  • I made a 2D ENGINE for Android, looking for cooperation.

    - by Roger Travis
    My name is Robert, I am an Android programmer and wanted to show off my latest project - a 2d game engine. You can see it in action here - https://play.google.com/store/apps/details?id=engineDemo.com My engine's main advantage is its ease of use. To have your level up and running, you'll need only 3 lines of code. ABoxView aboxView = new ABoxView(this); setContentView(aboxView); aboxView.loadLevel("level/level02"); Level are created in a special level constructor and object physical properties are stored in a corresponding XML file. I am looking to cooperate with those, who might be interesting in using my engine in their games. You can email me at [email protected] or post here. Thanks, Robert

  • Are there any open source projects for car engine sound simulation?

    - by Petteri Hietavirta
    I have been thinking how to create realistic sound for a car. The main sound is the engine, then all kind of wind, road and suspension sounds. Are there any open source projects for the engine sound simulation? Simply pitching up the sample does not sound too great. The ideal would be to something that allows me to pick type of the engine (i.e. inline-4 vs v-8), add extras like turbo/supercharger whine and finally set the load and rpm. Edit: Something like http://www.sonory.org/examples.html

  • What file formats and conventions should I support to make my game engine artist-friendly?

    - by Avi
    I'm writing a game engine, and I want to know what I should do to make it more artist-friendly. I don't want to be too limiting in terms of what file formats I support, etc. Some specific questions: Are there specific formats artists like to model in? Does it not matter because the 3D modeler abstracts the data storage away? Is it okay if I don't support per-vertex coloration in my game engine? If I have to store a diffuse, specular, ambient, and emissive color value for each vertex, it doubles the size of vertices in the buffer. Is it reasonable to ask artists to do all these things in textures / maps? Any other tips you have about making it so that artists have to adapt their style to my specific engine as little as possible would be nice.

  • Using Oracle Data in the Business Rules Engine

    - by Christopher House
    Yesterday I started working on some new functionality that I had planned to implement using the Business Rules Engine.  As I got further into it, I realized that some of my rules were going to need to reference some data that resides in an Oracle database.  I knew the Business Rules Composer supports using DataConnections and TypedDataTables, but I’d never used this functionality myself, so I wasn’t so sure how it would work with Oracle.  As it turns out, it’s very do-able, there’s just little hoop you need to jump through. I fired up BRC and my suspicions were quickly confirmed.  BRC only recognizes SQL Server databases when it comes to editing rules.  Not letting that deter me, I decided to see if I could “trick” BRE into using Oracle data. On my local SQL server, I created a new database and in that database, created a table that matched the schema of the table I wanted to use in the Oracle database.  I then set about creating my rules, referencing the new SQL Server database everywhere I wanted to use Oracle data.  Finally, I created a new class library and added a class that implements Microsoft.RuleEngine.IFactRetriever.  In that class, I added the necessary code to get a DataSet from the Oracle server, wrap it in a TypedDataTable and assert it into the rule engine.  It’s worth pointing out that in my IFactRetriever class, I made sure to set my DataSet name to the name of the database I’d referenced in the BRC and the DataTable’s name to the name of the table that I’d referenced in the BRC. After gac’ing the new class library and deploying my policy, I tested and everything worked as expected.
