• deriving activity diagram-based GUIs and CRUD them with a DB?

  - by Xin Tanaka

  i received a big book full of processes. i was thinking about the end user (they will be lawyers) and decided the best GUI would be showing activity diagrams or business processes. It reminded me Quickbooks and how non-accountants can successfully use it and understand accounting processes. i began doing research before sending my project to a bunch of programmers: is there some open source solution? can i use MS Visio libraries? which UML tool is programable? what about Eclipse and its modeling tools? etc etc the key points here are: relationships between events, artifacts, actors, etc should be stored in a database. processes or steps in a process should be easily modified by updating the database do this sounds too crazy? (should I explain a bit more why it must be programmed this way?)

• Entity Aspect (in Spring)

  - by niklassaers

  Hi guys, I'm having a bit of a problem defining my aspects. I've got a bunch of entities that I'd like to profile the get-methods in, so I've written the following pointcut and method @Pointcut("execution(* tld.myproject.data.entities.*.get*()") public void getEntityProperty() {} @Around("getEntityProperty()") public Object profileGetEntityProperty(ProceedingJoinPoint pjp) throws Throwable { long start = System.currentTimeMillis(); String name = pjp.getSignature().getName(); Object output = pjp.proceed(); long elapsedTime = System.currentTimeMillis() - start; if(elapsedTime > 100) System.err.println("profileGetEntityProperty: Entity method " + name + " execution time: " + elapsedTime + " ms."); return output; } I've got weaving turned on in my configuration, and aspects weaving into the business layer work just fine. Is my pointcut correctly written? Or is there something about entities that make them non-weavable? (my entity is prefixed with @Entity before the class definition) Cheers Nik

• Safari does not show images, but FireFox does

  - by Elliot

  I have a website that I am working on: http://keramed.com in FireFox on my Mac the image on the main page shows up. (The Endoshield DSEK Graft Injector) Now check in Safari and the image does not show up. I have tried taking the original .PSD and saving it as a .jpg or .png and it does not matter. I have commented out all stylesheets and this still does not solve it. The rest of my images are showing up, just not thing one. I just dont understand I am stumped. EDIT: Photoshop says it is an RGB 8-bit image.

• How can I use gnuplot to plot data that is in an un-friendly format?

  - by Zack

  I need to graph some data that is not exactly in the most friendly format, most examples or usage puts things in a nice column/table that is very easy to parse and graph. However I have the following format (and am a bit stuck as to how to tackle this): DATE1 label_1 xx yy DATE1 label_2 xx yy DATE1 label_3 xx yy DATE2 label_2 xx yy DATE2 label_3 xx yy DATE3 label_1 xx yy DATE3 label_2 xx yy DATE3 label_3 xx yy DATE4 label_2 xx yy DATE4 label_3 xx yy ...continues *I've added the extra space between the dates for readability. **Note: under DATE2,DATE4 label_1 is missing, i.e. the data file may have labels that come and go and should represent a discontinuity in the graph. I'd like to have the X-axis use the DATEX for the labels, and then create two lines for each label (xx and yy respectively). Does anyone have any suggestions on the best way to tackle this problem?

• First programming language: PHP, Ruby, Python?

  - by Victor

  I've been a Web developer for over 5 years and am looking to start building more complex Web apps. Currently, I know HTML/CSS/Javascript but I feel it's time to start learning something else. I work with a lot of applications based on PHP. I created a vBulletin forum on my own time and I would definitely want to build off of that since it has gained a bit of popularity. I also work with Wordpress quite often. All of the software I work with tends to be based on PHP but I hear a lot of people say Ruby or Python is better. Since I'm starting out, I really don't care which one I learn but I want to start right. Any recommendations for someone with HTML/CSS/Javascript knowledge but wants to branch out?

• Why is the proper "respond_to" format not getting called?

  - by humble_coder

  Hi All, I'm having a bit of an odd issue. Really too odd to type out, but here goes. Basically I have a controller that refuses to "respond_to" using javascript unless I assign my "chart.generate_xml" to a variable before the "respond_to" block like so: @xml = @chart.generate_xml(@begin_date,@end_date,1.hour) respond_to do |format| format.html format.js{ render :update do |page| page.insert_html :bottom, "chart-div", @xml #page.insert_html :bottom, "chart-div", @chart.generate_xml(@begin_date,@end_date,1.hour) end } If I remove the upper "@xml= …" portion and go with the lower "page.insert", the "format.js" section doesn't get called. And if I try to force the format with "request.format = :js", I get the javascript returned as text. I'm not doing anything special here in that method call, so I'm not sure why it would choose to respond any differently. FWIW, the method that triggers this controller action is using JS to do so, so I'm confused as to why "format.js" isn't always getting called. Thoughts? Best.

• Problems with sp_addlinkedserver in MSSQL 2000

  - by manneorama

  Hi! I'm having a bit of a problem with moving specific data from one server running MSSQL 2000 (A) and another running MSSQL 2008 (B). I'm writing a script according to customer specifications which is to be executed on A, populating tables in B with data. However, I can't seem to get the server link to work. -- Bunch of declarations here EXEC sp_addlinkedserver @server = @ServerName, @srvproduct = @ServerProduct, @provider = @ProviderString, @datasrc = @RemoteHost -- Data migration stuff here EXEC sp_dropserver @ServerName Now if I run the script in its entirety I get an error saying: Msg 7202, Level 11, State 2, Line 55 Could not find server 'remoteServer' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. However, if I higlight only the sp_addlinkedserver-part and execute that, there is no error and I can highlight the rest of the script and run it. What am I missing here? Please help! PS. If backup-restore was an option, I would have done that already.

• defining a simple implicit Arbitary

  - by FredOverflow

  I have a type Foo with a constructor that takes an Int. How do I define an implicit Arbitrary for Foo to be used with scalacheck? implicit def arbFoo: Arbitrary[Foo] = ??? I came up with the following solution, but it's a bit too "manual" and low-level for my taste: val fooGen = for (i <- Gen.choose(Int.MinValue, Int.MaxValue)) yield new Foo(i) implicit def arbFoo: Arbitrary[Foo] = Arbitrary(fooGen) Ideally, I would want a higher-order function where I just have to plug in an Int => Foo function. I managed to cut it down to: implicit def arbFoo = Arbitrary(Gen.resultOf((i: Int) => new Foo(i))) But I still feel like there has got to be a slightly simpler way.

• Static classes in PHP via abstract keyword?

  - by Boldewyn

  According to the PHP manual, a class like this: abstract class Example {} cannot be instantiated. If I need a class without instance, e.g. for a registry pattern: class Registry {} // and later: echo Registry::$someValue; would it be considered good style to simply declare the class as abstract? If not, what are the advantages of hiding the constructor as protected method compared to an abstract class? Rationale for asking: As far as I see it, it could a bit of feature abuse, since the manual refers to abstract classes more as like blueprints for later classes with instantiation possibility.

• Good portfolio projects

  - by David

  Hi, I am a recent graduate and am looking to start a career in web development. Its kind of a catch 22 at the moment as I have a fair bit of programming experience from university but not really in web development and to get a job in web development a portfolio is typically required. So, I am looking to start a building a few application in order to have something to show potential employers. Im more into the backend stuff although am just as comfortable with front end development. Does anyone have any thoughts on some potential projects that would be both relatively quick (as i need to get a job soon!) to build but show off enough programming knowlege / skills to be impressive to employers. At the moment i am also learning to use the zend framework and I would hope to find work using such a framework (mvc). My initial thoughts would be things like a webmail app or maybe a custom CMS. Any ideas would be greatley appreciated.

• How can I programatically test which CSS elements match my XHTML?

  - by Shawn Lauzon

  I have an application which generates XHTML documents which are styled with (mostly) static CSS. I'm currently using XPath and Hamcrest (Java) to verify that the documents are constructed correctly. However, I also need to verify that the correct CSS properties are matched. For example, I would like a test like this: Given XHTML element Foo, verify that the property "text-transform:uppercase" is applied. Ideally, I would like a Java framework that provides this. I've looked a bit at Selenium, but I don't see this type of functionality. Thanks ...

• Only Integrating Box2D collision detection in my 2d engine?

  - by Mr.Gando

  I have integrated box2d in my engine, ( Debug Draw, etc. ) and with a world I can throw in some 2d squares/rectangles etc. I saw this post, where the user is basically not using a world for collision detection, however the user doesn't explain anything about how he's using the manifold (b2Manifold), etc. Another post, is in the cocos2d forum, ( scroll down to the user Lam in the third reply ) Could anyone help me a bit with this?, basically want to add collision detection without the need of using b2World ,etc etc. Thanks a lot!

• Getting javascript mouse position relative to website prefferably without jQuery

  - by Constructor

  I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

• Jquery Slide to position on click

  - by Andy

  Here's a scenario... I have a column. In the column i have multiple divs with text inside each one. A bit like a list of categories. Which ever one is SELECTED gains a different background colour. What i would like to be able to do is use jquery so that when a different div is clicked on the background colour appears to slide behind the rest of the items until it reaches the one you selected. Does anyone have any idea if this can be done? And if so any idea on Markup? Any help is greatly appreciated.

• In Django, why is user.is_authenticated a method and not a member variable like is_staff

  - by luc

  Hello all, I've lost some time with a bug in my app due to user authentication. I think that it's a bit confusing but maybe someone can explain the reason and it will appear to me very logical. The user.is_staff is a member variable while user.is_authenticated is a method. However is_authenticated only returns True or False depending if the class is User or AnonymousUser (see http://docs.djangoproject.com/en/dev/topics/auth/) Is there a reason for that? Why user.is_authenticated is a method? Thanks in advance

• Simulating a mouse button click in Windows

  - by Ncarlson

  Hi everyone, I'm writing Remote Desktop clone in C++ using QT. So far I'm able to move the mouse cursor around fine. QT has a nice setPos function for that. However, I'm a bit lost as to what API/Library to use for simulating mouse button clicks. One method I'm aware of is to send the WM_(event) to a window using the window's HWND. However, I was hoping there was a more salient method for taking complete control over a mouse. Is there any other way to tell the operating system that the left mouse button has been clicked? Thanks.

• Auto Generated - CREATE Table Script in SQL 2008 throws error

  - by jack

  I scripted the tables in my dev database using SQL 2008 - generate scripts option (Datbase-right click-Tasks-Generate Scripts) and ran it on the staging database, but the script throws the below error for each table Msg 102, Level 15, State 1, Line 1 Incorrect syntax near '('. Msg 319, Level 15, State 1, Line 15 Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon. Below is the script for one of my table ALTER TABLE [dbo].[Customer]( [CustomerID] [int] IDENTITY(1,1) NOT NULL, [FirstName] [nvarchar](500) NULL, [LastName] [nvarchar](500) NULL, [DateOfBirth] [datetime] NULL, [EmailID] [nvarchar](200) NULL, [ContactForOffers] [bit] NULL, CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED ( [CustomerID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO Any help will be much appreciated.

• GUI system architecture?

  - by topright

  I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

• customise jQuery totemticker plugin

  - by Don

  I'm using the totemticker jQuery plugin, but need to be able to stop it programatically. It doesn't seem to provide this feature, so I had a look at the source code to see if I could add it myself. It seems that all I need to do is figure out how to call base.stop_interval() However, I can't seem to make the object that is stored in base accessible to callers. I've made a couple of unsuccesful atttempts, but hopefully someone who knows a bit more about how jQuery plugins work can point me in the right direction.

• SharePoint Cannot Log in after making entry in hosts file

  - by bmw0128

  I'm building a MOSS 2007 site on Windows 2008 R2, 64 bit. Not wanting to use my machine name or IP in the URL, I made an entry in my hosts file: 127.0.0.1 mydev.com I can surf to the URL, http://mydev.com, but when I try to log in (Windows Authentication), I am denied. I am able to successfully log in if I take out the hosts file entry, and surf to http:// Do I need to edit something else for the authentication to work when I want to use a custom URL like mydev.com that is only mapped in the hosts file?

• Strict pointer aliasing: any solution for a specific problem?

  - by doublep

  I have a problem caused by breaking strict pointer aliasing rule. I have a type T that comes from a template and some integral type Int of the same size (as with sizeof). My code essentially does the following: T x = some_other_t; if (*reinterpret_cast <Int*> (&x) == 0) ... Because T is some arbitary (other than the size restriction) type that could have a constructor, I cannot make a union of T and Int. (This is allowed only in C++0x only and isn't even supported by GCC yet). Is there any way I could rewrite the above pseudocode to preserve functionality and avoid breaking strict aliasing rule? Note that this is a template, I cannot control T or value of some_other_t; the assignment and subsequent comparison do happen inside the templated code. (For the record, the above code started breaking on GCC 4.5 if T contains any bit fields.)

• Posting an image and textual based data to a wcf service

  - by James Hay

  I have a requirement to write a web service that allows me to post an image to a server along with some additional information about that image. I'm completely new to developing web services (normally client side dev) so I'm a little stumped as to what I need to look into and try. How do you post binary data and plain text into a servic? What RequestFormat should I use? It looks like my options are xml or json. Can I use either of these? Bit of a waffly question but I just need some direction rather than a solution as I can't seem to find much online.

• NASM shift operators

  - by Hudson Worden

  How would you go about doing a bit shift in NASM on a register? I read the manual and it only seems to mention these operators , <<. When I try to use them NASM complains about the shift operator working on scalar values. Can you explain what a scalar value is and give an example of how to use and <<. Also, I thought there were a shr or shl operators. If they do exist can you give an example of how to use them? Thank you for your time.

• Complicated MySQL query?

  - by Scott

  I have two tables: RatingsTable that contains a ratingname and a bit whether it is a positive or negative rating: Good 1 Bad 0 Fun 1 Boring 0 FeedbackTable that contains feedback on things...the person rating, the rating and the thing rated. The feedback can be determined if it's a positive or negative rating based on RatingsTable. Jim Chicken Good Jim Steak Bad Ted Waterskiing Fun Ted Hiking Fun Nancy Hiking Boring I am trying to write an efficient MySQL query for the following: On a page, I want to display the the top 'things' that have the highest proportional positive ratings. I want to be sure that the items from the feedback table are unique...meaning, that if Jim has rated Chicken Good 20 times...it should only be counted once. At some point I will want to require a minimum number of ratings (at least 10) to be counted for this page as well. I'll want to to do the same for highest proportional negative ratings, but I am sure I can tweak the one for positive accordingly.
