  • How can I tackle 'profoundly found elsewhere' syndrome (inverse of NIH)?

    - by Alistair Knock
    How can I encourage colleagues to embrace small-scale innovation within our team(s), in order to get things done quicker and to encourage skills development? (the term 'profoundly found elsewhere' comes from Wikipedia, although it is scarcely used anywhere else apart from a reference to Proctor & Gamble) I've worked in both environments where there is a strong opposition to software which hasn't been developed in-house (usually because there's a large community of developers), and more recently (with far fewer central developers) where off-the-shelf products are far more favoured for the usual reasons: maintenance, total cost over product lifecycle, risk management and so on. I think the off the shelf argument works in the majority of cases for the majority of users, even though as a developer the product never quite does what I'd like it to do. However, in some cases there are clear gaps where the market isn't able to provide specifically what we would need, or at least it isn't able to without charging astronomical consultancy rates for a bespoke solution. These can be small web applications which provide a short-term solution to a particular need in one specific department, or could be larger developments that have the potential to serve a wider audience, both across the organisation and into external markets. The problem is that while development of these applications would be incredibly cheap in terms of developer hours, and delivered very quickly without the need for glacial consultation, the proposal usually falls flat because of risk: 'Who'll maintain the project tracker that hasn't had any maintenance for the past 7 years while you're on holiday for 2 weeks?' 'What if one of our systems changes and the connector breaks?' 'How can you guarantee it's secure/better/faster/cheaper/holier than Company X's?' With one developer behind these little projects, the answers are invariably: 'Nobody, but...' 'It will break, just like any other application would...' 'I, uh...' How can I better answer these questions and encourage people to take a little risk in order to stimulate creativity and fast-paced, short-lifecycle development instead of using that 6 months to consult about what tender process we might use?

  • Predicate crashing iPhone App!

    - by DVG
    To preface, this is a follow up to an inquiry made a few days ago: http://stackoverflow.com/questions/2981803/iphone-app-crashes-when-merging-managed-object-contexts Short Version: EXC_BAD_ACCESS is crashing my app, and zombie-mode revealed the culprit to be my predicate embedded within the fetch request embedded in my Fetched Results Controller. How does an object within an object get released without an explicit command to do so? Long Version: Application Structure Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller When a row gets clicked on the Platforms view, it sets an instance variable in Games View for that platform, then the Games Fetched Results Controller builds a fetch request in the normal way: - (NSFetchedResultsController *)fetchedResultsController{ if (fetchedResultsController != nil) { return fetchedResultsController; } //build the fetch request for Games NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Game" inManagedObjectContext:context]; [request setEntity:entity]; //predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"platform == %@", selectedPlatform]; [request setPredicate:predicate]; //sort based on name NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; //fetch and build fetched results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [sortDescriptor release]; [sortDescriptors release]; [predicate release]; [request release]; [aFetchedResultsController release]; return fetchedResultsController; } At the end of this method, the fetchedResultsController's _fetch_request - _predicate member is set to an NSComparisonPredicate object. All is well in the world. By the time - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section gets called, the _predicate is now a Zombie, which will eventually crash the application when the table attempts to update itself. I'm more or less flummoxed. I'm not releasing the fetched results controller or any of it's parts, and the only part getting dealloc'd is the predicate. Any ideas?

  • ASP.Net MVC, JS injection and System.ArgumentException - Illegal Characters in path

    - by Mose
    Hi, In my ASP.Net MVC application, I use custom error handling. I want to perform custom actions for each error case I meet in my application. So I override Application_Error, get the Server.GetLastError(); and do my business depending on the exception, the current user, the current URL (the application runs on many domains), the user IP, and many others. Obviousely, the application is often the target of hackers. In almost all the case it's not a problem to detect and manage it, but for some JS URL attacks, my error handling does not perform what I want it to do. Ex (from logs) : http://localhost:1809/Scripts/]||!o.support.htmlSerialize&&[1 When I got such an URL, an exception is raised when accessing the ConnectionStrings section in the web.config, and I can't even redirect to another URL. It leads to a "System.ArgumentException - Illegal Characters in path, etc." The screenshot below shows the problem : http://screencast.com/t/Y2I1YWU4 An obvious solution is to write a HTTP module to filter the urls before they reach my application, but I'd like to avoid it because : I like having the whole security being managed in one place (in the Application_Error() method) In the module I cannot access the whole data I have in the application itself (application specific data I don't want to debate here) Questions : Did you meet this problem ? How did you manage it ? Thanks for you suggestions, Mose

  • How to set ReceiveBufferSize for UDPClient? or Does it make sense to set? C#

    - by Jack
    Hello all. I am implementing a UDP data transfer thing. I have several questions about UDP buffer. I am using UDPClient to do the UDP send / receive. and my broadband bandwidth is 150KB/s (bytes/s, not bps). I send out a 500B datagram out to 27 hosts 27 hosts send back 10KB datagram back if they receive. So, I should receive 27 responses, right? however, I only get averagely 8 - 12 instead. I then tried to reduce the size of the response down to 500B, yes, I receive all. A thought of mine is that if all 27 hosts send back 10KB response at almost same time, the incoming traffic will be 270KB/s (likely), that exceeds my incoming bandwidth so loss happens. Am I right? But I think even if the incoming traffic exceeds the bandwidth, is the Windows supposed to put the datagram in the buffer and wait for receive? I then suspect that maybe the ReceiveBufferSize of my UdpClient is too small? by default, it is 8092B?? I don't know whether I am all right at these points. Please give me some help.

  • How to create a "Shell IDList Array" to support drag-and-drop of virtual files from C# to Windows Ex

    - by JustABill
    I started trying to implement drag-and-drop of virtual files (from a C# 4/WPF app) with this codeplex tutorial. After spending some time trying to figure out a DV_E_FORMATETC error, I figured out I need to support the "Shell IDList Array" data format. But there seems to be next to zero documentation on what this format actually does. After some searching, I found this page on advanced data transfer which said that a Shell IDList Array was a pointer to a CIDA structure. This CIDA structure then contains the number of PIDLs, and a list of offsets to them. So what the hell is a PIDL? After some more searching, this page sort of implies it's a pointer to an ITEMIDLIST, which itself contains a single member that is a list of SHITEMIDs. My next idea was to try dragging a file from another application with virtual files. I just got a MemoryStream back for this format. At least I know what class to provide for the thing, but that doesn't help at all for explaining what to put in it. So now that that's explained, I still have no idea how to create one of these things so that it's valid. There's two real questions here: What is a valid "abID" member for a SHITEMID? These virtual files only exist with my program; will the thing they are dragged to pass the "abID" back later when it executes GetData? Do they have to be system-unique? Why are there two levels of lists; a list of PIDLs and each PIDL has a list of SHITEMIDs? I'm assuming one of them is one for each file, but what's the other one for? Multiple IDs for the same file? Any help or even links that explain what I should be doing would be greatly appreciated.

  • Representing complex scheduled reoccurance in a database

    - by David Pfeffer
    I have the interesting problem of representing complex schedule data in a database. As a guideline, I need to be able to represent the entirety of what the iCalendar -- ics -- format can represent, but in a database. I'm not actually implementing anything relating to ics, but it gives a good scope of the type of rules I need to be able to model. I need to allow allow representation of a single event or a reoccurring event based on multiple times per day, days of the week, week of a month, month, year, or some combination of those. For example, the third Thursday in November annually, or the 25th of December annually, or every two weeks starting November 2 and continuing until September 8 the following year. I don't care about insertion efficiency but query efficiency is critical. The operation I will be doing most often is providing either a single date/time or a date/time range, and trying to determine if the defined schedule matches any part of the date/time range. Other operations can be slower. For example, given January 15, 2010 at 10:00 AM through January 15, 2010 at 11:00 AM, find all schedules that match at least part of that time. (i.e. a schedule that covers 10:30 - 11:00 still matches.) Any suggestions? I looked at http://stackoverflow.com/questions/1016170/how-would-one-represent-scheduled-events-in-an-rdbms but it doesn't cover the scope of the type of reoccurance rules I'd like to model.

  • My Android XML files can't find ActionBarSherlock themes

    - by MalcolmMcC
    I'm trying to develop an app with ActionBarSherlock and everything works except the theming. Specifically, I can import com.actionbarsherlock.app.*, extend SherlockActivity, but I always have this error in my manifest: Error: No resource found that matches the given name (at 'theme' with value '@style/Theme.Sherlock'). I know there have been plenty of questions asked about this, but they have not worked for me. I have tried refreshing the workspace cleaning all of my projects putting the line in both the <activity> and the <application> setting my targetSdkVersion and minSdkVersion to various values, in both my manifest and ABS's and I've tried the following variations, and probably others: android:theme="@style/Theme.Sherlock" android:theme="@android:style/Theme.Sherlock" theme="@style/Theme.Sherlock" theme="@android:style/Theme.Sherlock" theme="@theme/Theme.Sherlock" theme="@android:theme/Theme.Sherlock" It's worth noting that the autocomplete after I typed "@style/" was showing nothing, so I tried making my own style in styles.xml and then that showed up but still nothing from ActionBarSherlock. Also, in styles.xml, I tried to make my own theme to extend Theme.Sherlock, and @style/Theme.Sherlock was not found there either when I tried to add it as a parent. I tried loading the samples but got a JAR Mismatch. My conclusion is that somehow my xml files are unable to access the ABS library, but I'm at a loss as to how to fix it. Any help hugely appreciated.

  • PHP: retrieve all declared namespaces of a DOMElement

    - by soulmerge
    I am using the DOM extension to parse an xml file containing xml namespaces. I would have that namespace declarations are treated just like any other attribute, but my tests seem to disagree. I have a document that starts like this: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns="http://purl.org/rss/1.0/" xmlns:taxo="http://purl.org/rss/1.0/modules/taxonomy/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:syn="http://purl.org/rss/1.0/modules/syndication/" xmlns:prism="http://purl.org/rss/1.0/modules/prism/" xmlns:admin="http://webns.net/mvcb/" > And a test code like this: $doc = new DOMDocument(); $doc->loadXml(file_get_contents('/home/soulmerge/tmp/rss1.0/recent.xml')); $root = $doc->documentElement; var_dump($root->tagName); # prints 'string(7) "rdf:RDF"' var_dump($root->attributes->item(0)); # prints 'NULL' var_dump($root->getAttributeNode('xmlns')); # prints 'object(DOMNameSpaceNode)#3 (0) {}' So the questions are: Does anyone know where could I find the documentation of DOMNameSpaceNode? A search on php.net does not yield any useful result. How do I extract all those namespace declarations from that DOMElement?

  • Parse usable Street Address, City, State, Zip from a string

    - by Rob Allen
    Problem: I have an address field from an Access database which has been converted to Sql Server 2005. This field has everything all in one field. I need to parse out the individual sections of the address into their appropriate fields in a normalized table. I need to do this for approximately 4,000 records and it needs to be repeatable. Here are the rules for this exercise: 1 - no whining about how this should have been separate fields in the first place, we are often confronted with less than ideal situations and have to make the best of them 2- for this post, use any language you want 3- feel free to play code golf 4 - Assume an address in the US (for now) 5 - assume that the input string will sometimes contain an addressee (the person being addressed) and/or a second street address (i.e. Suite B) 6 - states may be abbreviated 7 - zip code could be standard 5 digit or zip+4 8 - there are typos in some instances UPDATE: In response to the questions posed, standards were not universally followed, I need need to store the individual values, not just geocode and errors means typo (corrected above) Sample Data: A. P. Croll & Son 2299 Lewes-Georgetown Hwy, Georgetown, DE 19947 11522 Shawnee Road, Greenwood DE 19950 144 Kings Highway, S.W. Dover, DE 19901 Intergrated Const.

  • PHP Installer Script

    - by totallymike
    I'm looking to create a fully functional installer for a slightly complicated web application using PHP. Basically, you go to URL/setup.php and you are asked a series of questions, and during the process a database is set up and a config file is populated according to the answers given. A good example of this is how Wordpress handles its install procedure, as well as any number of PHP applications. My question to you, oh great internet, is this: This technique is so prevalent that surely not everyone is re-inventing the wheel, is there a place I can go to find a basic walkthrough (not code, just a description) of the technique. Either that or a good book which outlines if not this specific technique, then the fundamentals relevant to this? I can bang out something ugly and probably make it work myself, but if there's a best known method I'd like to find it. Far more important than having a working function is to have a description of what's going on from step to step. I'd like to have the installer, but I really want to learn how it's done. Thanks, Mike

  • PHP: Profiling code and strict environment ~ Improving my coding

    - by DavidYell
    I would like to update my local working environment to be stricter in an effort to improve my code. I know that my code is okay, but as with most things there is always room for improvement. I use XAMPP on my local machine, for simplicities sake Apache Friends XAMPP (Basic Package) version 1.7.2 So I've updated my php.ini : error_reporting to be E_ALL | E_STRICT to help with the code standard. I've also enabled the XDebug extension zend_extension = "C:\xampp\php\ext\php_xdebug.dll" which seems to be working, having tested some broken code and got the nice standard orange error notice. However, having read this question, http://stackoverflow.com/questions/133686/what-is-the-best-way-to-profile-php-code and enabled the profiler, I cannot seem to create a cachegrind file. Many of the guides that I've looked at seem to think you need to install XDebug in XAMPP which leads me to think they are out of date, as XDebug is bundled with XAMPP these days. So I would appreciate it if anyone can help point me in the right direction with both configuring XDebug to output grind files, and or just a great set of default settings for the XDebug config in XAMPP. Seems there is very little documentation to go on. If people have tips on integrating these tools with Netbeans, that would be awesomesauce. I'm happy to get suggestions on other things that I can do to help tighten up my php code, both syntactically and performance wise Thanks, and apologies for the rambling question(s)! Ninja edit I should menion that I'm using named vhosts as my Apache configuration, which I think is why running XDebug on port 9000 isn't working for me. I guess I'd need to edit my vhost to include port 9000

  • Customizing the TFS 2008 build sequence to avoid compilation and deploy SSRS

    - by Andrew
    I'm trying to create a CI process for SQL Server Reporting Services. I am fairly new to TFS but quite experienced with MSBuild. In the past I've used a combination of MSBuild with Team City so the whole build process is more or less custom. Here lies the start of my problems, as the solution I am deploying only contains Report Server projects (rds), no compilation is required. I thought that I would override the the first default task that TFS runs (EndToEndIteration) to override the default TFS build sequence and inject my own. The first snag that I have come across is that the build always fails, how can I set the status of the build to success? Currently the EndToEndIteration task is very light and only has a message. Is this the best method to create a custom build process in TFS where compilation is not required? Or should I use the default sequence and override one of the hook tasks mentioned in http://msdn.microsoft.com/en-us/library/aa337604%28VS.80%29.aspx (ie: AfterCompile) The core steps that I'd like to achieve are: Bundle the RDL and datasource files Connect to the host server to register/deploy the reports Re-apply any subscriptions that previously existed Run tests to verify the deployment succeeded and is returning results as expected I have found another article on Report services deployment: http://stackoverflow.com/questions/88710/reporting-services-deployment But it doesn't mention the best practice for customizing the standard build process. Any help would be appreciated.

  • bin-deploying DLLs banned in leiu of GAC on shared IIS 6 servers

    - by craigmoliver
    I need to solicit feedback about a recent security policy change at an organization I work with. They have recently banned the bin-deployment of DLLs to shared IIS 6 application servers. These servers host many isolated web application pools. The new rules require all DLLs to be installed in GAC. The is a problem for me because I bin-deploy several dlls including the ASP.NET MVC Framework, HTML Agility Pack, ELMAH, and my own shared class libraries. I do this because: Eliminates web application server dependencies to the Global Assembly Cache. Allows me (the developer) to have control of what goes on inside my application. Enables the application to deployed as a "package". Removes application deployment burden from the server administrators. Now, here are my questions. From a security perspective what are the advantages to using the GAC vs. bin-deployment? Is it possible to host multiple versions of the same DLL in the GAC? Has anyone run into similar restrictions?

  • Java: Clearing up the confusion on what causes a connection reset

    - by Zombies
    There seems to be some confusion as well contradicting statements on various SO answers: http://stackoverflow.com/questions/585599/whats-causing-my-java-net-socketexception-connection-reset . You can see here that the accepted answer states that the connection was closed by other side. But this is not true, closing a connection doesn't cause a connection reset. It is cauesed by "an underlying TCP/IP error." What I want to know is if a SocketException: Connection reset means really besides "unerlying TCP/IP Error." What really causes this? As I doubt it has anything to do with the connection being closed (since closing a connection isn't an exception worthy flag, and reading from a closed connection is, but that isn't an "underlying TCP/IP error." My hypothesis is this Connection reset is caused from a server's failure to acknowledge an ACK packet (either wholly or just improperly as per TCP/IP). And that a SocketTimeoutException is generated only when no data is generated to be read (since this is thrown during a read after a certain duration, and read is waiting for data, but is not concerned with ACK packets). In other words, read() throws SocketTimeoutException if it didn't read any bytes of actual data (DATA LAYER) in its allotted time.

  • How to show a server side error message in a popup using php

    - by Fero
    Hi all, I found some of the similar questions here but they are all in C#. So kindly tell me the easiest way to show the server side error message using popup. The popup may be anything like thickbox, modalpopup etc... Here is the sample code. I didn't get the error message in the popup. <script type="text/javascript" src="thickbox/jquery-latest.js"></script> <script type="text/javascript" src="thickbox/thickbox.js"></script> <link href="thickbox/thickbox.css" rel="stylesheet" type="text/css" /> <span class="prtexterror" style="color:#FF0000;display:none;" id="hiddenModalContent" >{$error_login}</span> {literal} <script language="javascript" type="text/javascript"> $(document).ready(function() { tb_show("Please, login", "?tb_inline=true&inlineId=hiddenModalContent&height=180&width=300&modal=true", null); }); </script> {/literal} Any other ways are always welcome. thanks in advance

  • How to exit current activity to homescreen (without using "Home" button)?

    - by steff
    Hi everyone, I am sure this will have been answered but I proved unable to find it. So please excuse my redundancy. What I am trying to do is emulating the "Home" button which takes one back to Android's homescreen. So here is what causes me problems: I have 3 launcher activities. The first one (which is connected to the homescreen icon) is just a (password protected) configuration activity. It will not be used by the user (just admin) One of the other 2 (both accessed via an app widget) is a questionnaire app. I'm allowing to jump back between questions via the Back button or a GUI back button as well. When the questionnaire is finished I sum up the answers given and provide a "Finish" button which should take the user back to the home screen. For the questionnaire app I use a single activity (called ItemActivity) which calls itself (is that recursion as well when using intents?) to jump from one question to another: Questionnaire.serializeToXML(); Intent i = new Intent().setClass(c, ItemActivity.class); if(Questionnaire.instance.getCurrentItemNo() == Questionnaire.instance.getAmountOfItems()) { Questionnaire.instance.setCompleted(true); } else Questionnaire.instance.nextItem(); startActivity(i); The final screen shows something like "Thank you for participating" as well as the formerly described button which should take one back to the homescreen. But I don't really get how to exit the Activity properly. I've e.g. used this.finish(); but this strangely brings up the "Thank you" screen again. So how can I just exit by jumping back to the homescreen?? Sorry for the inconvinience. Regards, Steff

  • Understanding MongoDB (and NoSQL in general) and how to make the best use of it

    - by Earlz
    Hello, I am beginning to think that my next project I am wanting to do would work better with a NoSQL solution. The project would either involve a ton of 2-column tables or a ton of dynamic queries with dynamically generated columns in a traditional SQL database. So I feel a NoSQL database would be much cleaner. I'm looking at MongoDB and it looks pretty promising. Anyway, I'm attempting to make sense of it all. Also, I will be using MongoMapper in Ruby. Anyway though, I'm confused as to how to layout things in such a freeform database. I've read http://stackoverflow.com/questions/2170152/nosql-best-practices and the answer there says that normalization is usually bad in a NoSQL DB. So how would be the best way of laying out say a simple blog with users, posts, and comments? My natural thought was to have three collections for each and then link them by a unique ID. But this apparently is wrong? So, what are some of the ways to lay out such a thing? My concern with the answer given in the other question is, what if the author's name changed? You'd have to go through updating a ton of posts and comments. But is this an okay thing to do with NoSQL?

  • Python - Things one MUST avoid

    - by Anurag Uniyal
    Today I was bitten again by "Mutable default arguments" after many years. I usually don't use mutable default arguments unless needed but I think with time I forgot about that, and today in the application I added tocElements=[] in a pdf generation function's argument list and now 'Table of Content' gets longer and longer after each invocation of "generate pdf" :) My question is what other things should I add to my list of things to MUST avoid? 1 Mutable default arguments 2 import modules always same way e.g. 'from y import x' and 'import x' are totally different things actually they are treated as different modules see http://stackoverflow.com/questions/1459236/module-reimported-if-imported-from-different-path 3 Do not use range in place of lists because range() will become an iterator anyway, so things like this will fail, so wrap it by list myIndexList = [0,1,3] isListSorted = myIndexList == range(3) # will fail in 3.0 isListSorted = myIndexList == list(range(3)) # will not same thing can be mistakenly done with xrange e.g myIndexList == xrange(3). 4 Catching multiple exceptions try: raise KeyError("hmm bug") except KeyError,TypeError: print TypeError It prints "hmm bug", though it is not a bug, it looks like we are catching exceptions of type KeyError,TypeError but instead we are catching KeyError only as variable TypeError, instead use try: raise KeyError("hmm bug") except (KeyError,TypeError): print TypeError

    i must say i m not very good at this. and you probably know that (cause noone bothers to answer my questions) but i will keep on trying!!! lol here it goes! i wanted to find an "easy" way to use the pinch/zoom function on my app! so i decided to use a UIScrollView. so far so good. i load my image from an sqlite db like so: - (void)loadView { self.title = @"ScrollView"; imageView = [[UIImageView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame]; imageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; imageView.contentMode = UIViewContentModeScaleAspectFit; imageView.backgroundColor = [UIColor blackColor]; self.view = imageView;} and - (void)viewWillAppear:(BOOL)animated {imageView.image = entity.imageA} I followed a tutorial but i cnnot seem to be able to load my image at all: - (void)vieDidLoad { imageView = [[UIImageView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame]; imageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; imageView.contentMode = UIViewContentModeScaleAspectFit; imageView.backgroundColor = [UIColor blackColor]; //when i have this it does load the image but when i cant load my own data!! /*UIImageView *tempImageView = [[UIImageView alloc] initWithImage:[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://www.austinbull.com/clonemines.png"]]]]; [self setMyImage:tempImageView]; [tempImageView release];*/ myScrollView.contentSize = CGSizeMake(imageView.frame.size.width, imageView.frame.size.height); myScrollView.maximumZoomScale = 4.0; myScrollView.minimumZoomScale = 0.75; myScrollView.clipsToBounds = YES; myScrollView.delegate = self; [myScrollView addSubview:imageView]; self.view = scrollView; [window makeKeyAndVisible]; } (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myImage; } any help would be appreciated! thank you for your time!

  • Modelling deterministic and nondeterministic data separately

    - by Superstringcheese
    I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

  • Persistant Http client connections in java

    - by Akusete
    I am trying to write a simple Http client application in Java and am a bit confused by the seemingly different ways to establish Http client connections, and efficiently re-use the objects. Current I am using the following steps (I have left out exception handling for simplicity) Iterator<URI> uriIterator = someURIs(); HttpClient client = new DefaultHttpClient(); while (uriIterator.hasNext()) { URI uri = uriIterator.next(); HttpGet request = new HttpGet(uri); HttpResponse response = client.execute(request); HttpEntity entity = response.getEntity(); InputStream s = entity.getContent(); processStream (); s.close(); } In regard to the code above, my questions is: Assuming all URI's are pointing to the same host (but different resources on that host). What is the recommended way to use a single http connection for all requests? And how do you close the connection after the last request? --edit: Also what is the difference between using uri.openConnection(), versus HttpClient? Which is preferable, and what other methods exist?

  • How to implement a download for dynamic files in asp.net with masterpages

    - by Tim
    Hello, the title says it all. I have seen some similar questions on SO like this or this, but either i have overlooked something or my requirement is different, neither works. My situation is following: i have a Masterpage one of its contentpage is called MasterData.aspx MasterData has an asp.net ajax tabcontainer control with one usercontrol in every tabpanel these usercontrols(f.e. MD_Customer.ascx)hold the main content(like a normal page) they all have GridViews in it and i want to provide an Excel-Export-Button What i've tried is is to use an iframe like here. But the function that adds the iframe to the document gets never called and therefore i never see the save-as-dialog. Maybe this is caused by using a MasterPage. Does somebody has an idea on how to provide a button in an UpdatePanel that causes an async postback, so that i can generate a CSV dynamically in codebehind and write it to the response? Thank you in advance. aspx-markup: <asp:UpdatePanel ID="UpdGridInfo" runat="server" > <ContentTemplate> <asp:Label ID="LblInfo" Font-Underline="false" runat="server" CssClass="content" ></asp:Label>&nbsp;&nbsp; <asp:ImageButton ToolTip="export to Excel" style="vertical-align:bottom" ID="BtnExcelExport" ImageUrl="~/images/excel2007logo.png" runat="server" /> </ContentTemplate> </asp:UpdatePanel> and the BtnExportExcel codebehind handler(of course it cannot work to write the csv to the response of this page): Private Sub BtnExcelExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles BtnExcelExport.Click Dim csv As String = tableToCsv(DirectCast(Me.GridSource, DataTable)) Response.AddHeader("Content-disposition", "attachment; filename=RuleConfigurationFile.csv") Response.ContentType = "application/octet-stream" Response.Write(csv) Response.End() End Sub

  • Creating ODT and PDF files as end result

    - by Bill Zimmerman
    Hello, I've been working on an app to create various document formats for a while now, and I've had limited success. Ideally, I'd like to dynamically create a fairly simple ODT/PDF/DOC file. I've been focusing my efforts on ODT, because it is editable, and open enough that there are several tools which will convert it to any of the other formats I need. The problem is that the ODT XML files are NOT simple, and there aren't any good-quality API's I could find (especially in python). So far, I've had the most success creating a template ODT file, and then manipulating the DOM in python as needed. This is ok generally, but is quickly becoming inadequate and requires too much tweaking every single time I need to alter one of the templates. The requirements are: 1) Produce a simple document that will have lists, paragraphs, and the ability to draw simple graphics on the page (boxes, circles, etc...) 2) The ability to specify page size, and the different formats should generally print the exact same output when sent to a printer My questions: 1) Are there any other ways I can produce ODT/PDF/DOC files? 2) Would LaTeX be acceptable? I've never really used it, does anyone have experience converting LaTeX files into other formats? 3) Would it be possible to use HTML? There are a lot of converters online. Technically you can specify dimensions in mm/cm, etc..., but I am worried that the printed output will differ between browsers/converters.... Any other ideas?
