  • Pros and cons of programmatically enforcing foreign key than in database

    - by Jeffrey
    It is causing so much trouble in terms of development just by letting database enforcing foreign key. Especially during unit test I can’t drop table due to foreign key constrains, I need to create table in such an order that foreign key constrain warning won’t get triggered. In reality I don’t see too much point of letting database enforcing the foreign key constrains. If the application has been properly designed there should not be any manual database manipulation other than select queries. I just want to make sure that I am not digging myself into a hole by not having foreign key constrains in database and leaving it solely to the application’s responsibility. Am I missing anything? P.S. my real unit tests (not those that use mocking) will drop existing tables if the structure of underlying domain object has been modified.

  • Are these tables too big for SQL Server or Oracle

    - by Jeffrey Cameron
    Hey all, I'm not much of a database guru so I would like some advice. Background We have 4 tables that are currently stored in Sybase IQ. We don't currently have any choice over this, we're basically stuck with what someone else decided for us. Sybase IQ is a column-oriented database that is perfect for a data warehouse. Unfortunately, my project needs to do a lot of transactional updating (we're more of an operational database) so I'm looking for more mainstream alternatives. Question Given these tables' dimensions, would anyone consider SQL Server or Oracle to be a viable alternative? Table 1 : 172 columns * 32 million rows Table 2 : 453 columns * 7 million rows Table 3 : 112 columns * 13 million rows Table 4 : 147 columns * 2.5 million rows Given the size of data what are the things I should be concerned about in terms of database choice, server configuration, memory, platform, etc.?

  • unable to add objects to saved collection in GAE using JDO

    - by Jeffrey Chee
    I have a ClassA containing an ArrayList of another ClassB I can save a new instance of ClassA with ClassB instances also saved using JDO. However, When I retrieve the instance of Class A, I try to do like the below: ClassA instance = PMF.get().getPersistenceManager().GetObjectByID( someid ); instance.GetClassBArrayList().add( new ClassB(...) ); I get an Exception like the below: Uncaught exception from servlet com.google.appengine.api.datastore.DatastoreNeedIndexException: no matching index found.. So I was wondering, Is it possible to add a new item to the previously saved collection? Or was it something I missed out. Best Regards

  • Issue with javascript array object

    - by ezhil
    I have the below JSON response. I am using $.getJSON method to loads JSON data and using callback function to do some manipulation by checking whether it is array as below. { "r": [{ "IsDefault": false, "re": { "Name": "Depo" }, "Valid": "Oct8, 2013", "Clg": [{ "Name": "james", "Rate": 0.05 }, { "Name": "Jack", "Rate": 0.55 }, { "Name": "Mcd", "Rate": 0.01, }], }, { "IsDefault": false, "re": { "Name": "Depo" }, "Valid": "Oct8, 2013", "Clg": [{ "Name": "james", "Rate": 0.05 }, { "Name": "Jack", "Rate": 0.55 }, { "Name": "Mcd", "Rate": 0.01, }], }, { "IsDefault": false, "re": { "Name": "Depo" }, "Valid": "Oct8, 2013", "Clg": [{ "Name": "james", "Rate": 0.05 }, { "Name": "Jack", "Rate": 0.55 }, { "Name": "Mcd", "Rate": 0.01, }], }] } I am passing the json responses on both loadFromJson1 and loadFromJson2 function as "input" as parameter as below. var tablesResult = loadFromJson1(resultstest.r[0].Clg); loadFromJson1 = function (input) { if (_.isArray(input)) { alert("loadFromJson1: Inside array function"); var collection = new CompeCollection(); _.each(input, function (modelData) { collection.add(loadFromJson1(modelData)); }); return collection; } return new CompeModel({ compeRates: loadFromJson2(input), compName: input.Name }); }; loadFromJson2 = function (input) // here is the problem, the 'input' is not an array object so it is not going to IF condition of the isArray method. { if (_.isArray(input)) { alert("loadFromJson2: Inside array function"); //alert is not coming here though it is an array var rcollect = new rateCollection(); _.each(input, function (modelData) { rcollect.add(modelData); }); return rcollect; } }; The above code i am passing json responses for both loadFromJson1 and loadFromJson2 function as "input". isArray is getting true on only loadFromJson1 function and giving alert inside the if condition but not coming in loadFromJson2 function though i am passing the same parameter. can anyone tell me why loadFromJson2 function is not getting the alert inside if condition though i pass array object?

  • WebSphere MQ/MQSeries - Possible to send a message to multiple queues with single call?

    - by Jeffrey White
    I'm queuing messages to a WebSphere MQ queue (NB: A point-to-point queue -- not a topic) using a stored procedure in my Oracle database. Is there a way to publish each message to multiple queues with a single call? What I would like is to find a solution that would incur zero additional latency on my database compared to sending the message to a single queue. Solutions that involve changing my WebSphere MQ settings are certainly welcome! What I had in mind was somehow creating a "clone" queue that got all the same messages as the original one, but I've been unable to locate anything like this in the documentation. Thanks, Jeff

  • Import CSV from url address and export as XML -- Rails

    - by Jeffrey
    Two questions: How can I import a file from a web address, without a form? Example: Organisation.import(:from = 'http://wufoo.com/report.csv') How can I use xml builder without pulling from the db? More Info My company uses wufoo for web forms. The data from wufoo is exported as csv files. To get the data into my company's cms, it needs to be formatted as xml. I don't need to store any of the data, aside from the url to the csv file. I thought this might work well as a simple rails app.

  • jQuery table filter with text, checkboxes, selects

    - by Jeffrey
    Need to filter a table from outside of the table, with a text search, checkboxes, and selects. PicNet Table Filter for jQuery works for both searching and using checkboxes outside of the table... though I can't find any examples of how to get a select box to work. Anyone know? *I might be getting too specific here, but thought I'd at least inquire. I'm also open to possibilities other than PicNet.

  • Android App Widget: Data storage

    - by Jeffrey
    Hello everyone, I'm implementing a home screen app widget. I was wondering which is better to store/read data: SharedPreferences or a SQLite database? The data is accessed from an AppWidgetProvider (similar to a BroadcastReceiver), and any given instance of the widget displays different data based on appWidgetId. Is one way or the other frowned upon? Thanks for your time.

  • Double-Escaped Unicode Javascript Issue

    - by Jeffrey Winter
    I am having a problem displaying a Javascript string with embedded Unicode character escape sequences (\uXXXX) where the initial "\" character is itself escaped as "&#92;" What do I need to do to transform the string so that it properly evaluates the escape sequences and produces output with the correct Unicode character? For example, I am dealing with input such as: "this is a &#92;u201ctest&#92;u201d"; attempting to decode the "&#92;" using a regex expression, e.g.: var out = text.replace('/&#92;/g','\'); results in the output text: "this is a \u201ctest\u201d"; that is, the Unicode escape sequences are displayed as actual escape sequences, not the double quote characters I would like.

  • 'Forward-Compatible' Program Design

    - by Jeffrey Kern
    The majority of my questions I've asked here so far on StackOverflow have been how to implement individual concepts and techniques towards developing a software-based NES clone via the XNA environment. The small samples that I've thrown together on my PC work relatively great and everything. Except I hit a brick wall. How do I merge all of these samples together. Having proof-of-concept is amazing, except when you need it to go beyond just that. I now have samples strewn about that I'm trying to merge, some of them incomplete. And now I'm stuck with the chicken-and-the-egg situation of where I would like to incorporate these samples together, to make sure they work, but I cannot without test data. And I don't have tools to create test data, because they'd need to be based off of the individual pieces that need to be put together. In my mind, I'm having nightmares with circular reference. For my sample data, I am hoping to save it in XML and write a specification - and then make sample data by hand - but I'm too paranoid of manually creating an XML file full of incorrect data and blaming it on my code, or vice-versa. It doesn't help that the end-result of my work is graphic-oriented, which makes it interseting how a graphic on the screen can be visualized in XML Nodes. I guess, my question is this: What design patterns and disciplines exist in the coding world that address this type of concern? I've always relied on brute-force coding and restarting a project with a whole new code base in attempts to further along my goals, but I doubt that would be the best way to do so. Within my college career, the majority of my programming was to work on simple projects that came out of a book, or with a given correct data set and a verifyable result. I don't have that, as my own design documents that I am going by could be terribly wrong.

  • Best practices retrieving XML/stream from HTTP in Android

    - by Jeffrey
    Hello everyone, what are the best practices parsing XML from an HTTP resource in Android? I've been using HttpURLConnection to retrieve an InputStream, wrapping it with a BufferedInputStream, and then using SAX to parse the buffered stream. For the most part it works, though I do receive error reports of SocketTimeoutException: The operation timed out or general parsing error. I believe it's due to the InputStream. Would using HttpClient instead of HttpURLConnection help? If yes, why? Should the stream be output to a file, having the file parsed instead of the stream? Any input or direction would be greatly appreciated. Thanks for your time.

  • Is it possible to broadcast audio to shoutcast / icecast / other server? from flash player?

    - by Jeffrey
    I am trying to create a flash client that can stream audio to an online radio server. Theoretically a user could enter the server info / login, and then connect and start sending data to the server which could then be broadcasted and listened to by other clients. I don't think this would be very hard, but am unsure about what data formats to use and what is the best server for the job. I'd like to be able to use one of the most popular radio servers like shoutCast. Any ideas? Thanks in advance.

  • JSF Templating without RAD

    - by Jeffrey Knight
    I have a set of jsp's based off a jtpl template. The template (jtpl file) looks like this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <%-- tpl:metadata --%> <%-- jsf:codeBehind language="java" location="/JavaSource/pagecode/my.java" --%> <%-- /jsf:codeBehind --%> <%-- /tpl:metadata --%> <%@taglib uri="http://www.ibm.com/jsf/html_extended" prefix="hx"%> <%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <HTML> <%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <f:view> <HEAD> ... Without using RAD, how can I change the jtpl (template) and regenerate jsp? I'm looking for a command line solution. Related question: is the jsp intended to be rendered from the template design-time in the IDE, or runtime on the server?

  • Avoiding Multiple Dialog Calls with htaccess

    - by Jeffrey J Weimer
    OK, I'm new to this, so pardon if the question is already a FAQ. Searching multiple places still leaves me dumbfounded. I have a Web site generated with iWeb09/Mac hosting on an ISP. To secure certain pages, I am trying to set up .htaccess + .htpasswd files. The basic directory structure is ... Main index.html Images.html Images (some css, js stuff) Media Image01 Image01.jpeg ... Image02 Image02.jpeg ... I want to password protect access to the Images directory and all the files therein. The index.html file has a link to the Images.html file that contains the layout for the files in the Images directory. I have put a basic .htaccess file at the Main level that restricts access via ... <Files "Images.html"> AuthType Basic AuthName "Images" AuthUserFile /Main/.htpasswd AuthGroupFile /dev/null Require valid-user </Files> I have then created a valid .htpasswd file. All works at the start, however after the first call to set up the Images.html page, the secure login prompt is displayed multiple times, presumably once for every sub-sub-directory Images/Media/ImageXX (with multiple sub-directories, I just give up after two or three times). I have also tried placing the .htaccess file inside the Images directory with the same problem. Recommendations I have seen suggest a better convention is needed in the basic .htaccess file itself. Alternatively, perhaps a companion .htaccess is needed in the Images directory. So, how do I fix this problem? -- JJW

  • 'Bank Switching' Sprites on old NES applications

    - by Jeffrey Kern
    I'm currently writing in C# what could basically be called my own interpretation of the NES hardware for an old-school looking game that I'm developing. I've fired up FCE and have been observing how the NES displayed and rendered graphics. In a nutshell, the NES could hold two bitmaps worth of graphical information, each with the dimensions of 128x128. These are called the PPU tables. One was for BG tiles and the other was for sprites. The data had to be in this memory for it to be drawn on-screen. Now, if a game had more graphical data then these two banks, it could write portions of this new information to these banks -overwriting what was there - at the end of each frame, and use it from the next frame onward. So, in old games how did the programmers 'bank switch'? I mean, within the level design, how did they know which graphic set to load? I've noticed that Mega Man 2 bankswitches when the screen programatically scrolls from one portion of the stage to the next. But how did they store this information in the level - what sprites to copy over into the PPU tables, and where to write them at? Another example would be hitting pause in MM2. BG tiles get over-written during pause, and then get restored when the player unpauses. How did they remember which tiles they replaced and how to restore them? If I was lazy, I could just make one huge static bitmap and just grab values that way. But I'm forcing myself to limit these values to create a more authentic experience. I've read the amazing guide on how M.C. Kids was made, and I'm trying to be barebones about how I program this game. It still just boggles my mind how these programmers accomplisehd what they did with what they had. EDIT: The only solution I can think of would be to hold separate tables that state what tiles should be in the PPU at what time, but I think that would be a huge memory resource that the NES wouldn't be able to handle.

  • C# WebBrowser Invoke issue

    - by James Jeffrey
    I am logging into facebook using a web browser. Everything works, but the problem is when I invoke the button click I need to check if the password is correct but, the check seems to happen before the button is invoked which makes no sense at all because the checking code is after the invoke. private void Facebook_Login(String username, String password) { webBrowser1.Url = new Uri("http://m.facebook.com"); while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); HtmlElementCollection inputs = webBrowser1.Document.GetElementsByTagName("input"); foreach(HtmlElement input in inputs) { if (input.GetAttribute("name") == "email") { input.SetAttribute("value", "[email protected]"); } if (input.GetAttribute("name") == "pass") { input.SetAttribute("value", "kelaroostj"); // dont worry that pass wont work lol. } if (input.GetAttribute("name") == "login") { input.InvokeMember("click"); } } while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); HtmlElementCollection bs = webBrowser1.Document.GetElementsByTagName("b"); foreach(HtmlElement b in bs) { MessageBox.Show(b.InnerHtml); } Log_Message("Logged into Facebook with: [email protected]"); }

  • How to Command Query Responsibility Segregation (CQRS) with ASP.NET MVC?

    - by Jeffrey
    I have been reading about Command Query Responsibility Segregation (CQRS). I sort of wonder how would this work with ASP.NET MVC? I get the idea of CQRS conceptually it sounds nice and sure does introduce some complexities (event and messaging pattern) compared to the "normal/common" approach . Also the idea of CQRS sort of against the use of ORM in some ways. I am trying to think how I could use this pattern in the coming projects so if anyone has experience in combining CQRS with ASP.NET MVC and NHibernate please give some concrete examples to help me better understand CQRS and use with ASP.NET MVC. Thanks!
