  • What is logical cohesion, and why is it bad or undesirable?

    - by Matt Fenwick
    From the c2wiki page on coupling & cohesion: Cohesion (interdependency within module) strength/level names : (from worse to better, high cohesion is good) Coincidental Cohesion : (Worst) Module elements are unrelated Logical Cohesion : Elements perform similar activities as selected from outside module, i.e. by a flag that selects operation to perform (see also CommandObject). i.e. body of function is one huge if-else/switch on operation flag Temporal Cohesion : operations related only by general time performed (i.e. initialization() or FatalErrorShutdown?()) Procedural Cohesion : Elements involved in different but sequential activities, each on different data (usually could be trivially split into multiple modules along linear sequence boundaries) Communicational Cohesion : unrelated operations except need same data or input Sequential Cohesion : operations on same data in significant order; output from one function is input to next (pipeline) Informational Cohesion: a module performs a number of actions, each with its own entry point, with independent code for each action, all performed on the same data structure. Essentially an implementation of an abstract data type. i.e. define structure of sales_region_table and its operators: init_table(), update_table(), print_table() Functional Cohesion : all elements contribute to a single, well-defined task, i.e. a function that performs exactly one operation get_engine_temperature(), add_sales_tax() (emphasis mine). I don't fully understand the definition of logical cohesion. My questions are: what is logical cohesion? Why does it get such a bad rap (2nd worst kind of cohesion)?

  • Is a Mission Oriented Architecture (MOA) a better way to describe things than SOA?

    - by Brian Langbecker
    I might sound like a troll, but I would like to seriously understand this deeper. The place I work at has started to use the term MOA, versus SOA as we believe it drives more clarity and want to compare it to the true goals of SOA. A Mission Oriented Architecture is an approach whereby an application is broken down into various business mission elements, with the database, file assets, batch and real time functionality all tightly coupled in terms of delivering that piece of the functionality. The mission allows the developers to focus on a specific piece of functionality to get it right, and to build it with the ability for that piece to scale as an independent entity within the overall application. By tightly coupling the data, file assets and business logic you achieve the goals of working on a very large problem in bite size pieces. Some definitions of SOA mix it up with what is essentially a method call on a web service versus a true "service". As an architect, I have always found it fun getting everyone on the same page regarding SOA. Is it better to call it a "mission" versus a "service"?

  • Extract all related class type aliasing and enum into one file or not

    - by Chen OT
    I have many models in my project, and some other classes just need the class declaration and pointer type aliasing. It does not need to know the class definition, so I don't want to include the model header file. I extract all the model's declaration into one file to let every classes reference one file. model_forward.h class Cat; typedef std::shared_ptr<Cat> CatPointerType; typedef std::shared_ptr<const Cat> CatConstPointerType; class Dog; typedef std::shared_ptr<Dog> DogPointerType; typedef std::shared_ptr<const Dog> DogConstPointerType; class Fish; typedef std::shared_ptr<Fish> FishPointerType; typedef std::shared_ptr<const Fish> FishConstPointerType; enum CatType{RED_CAT, YELLOW_CAT, GREEN_CAT, PURPLE_CAT} enum DogType{HATE_CAT_DOG, HUSKY, GOLDEN_RETRIEVER} enum FishType{SHARK, OCTOPUS, SALMON} Is it acceptable practice? Should I make every unit, which needs a class declaration, depends on one file? Does it cause high coupling? Or I should put these pointer type aliasing and enum definition inside the class back? cat.h class Cat { typedef std::shared_ptr<Cat> PointerType; typedef std::shared_ptr<const Cat> ConstPointerType; enum Type{RED_CAT, YELLOW_CAT, GREEN_CAT, PURPLE_CAT} ... }; dog.h class Dog { typedef std::shared_ptr<Dog> PointerType; typedef std::shared_ptr<const Dog> ConstPointerType; enum Type{HATE_CAT_DOG, HUSKY, GOLDEN_RETRIEVER} ... } fish.h class Fish { ... }; Any suggestion will be helpful.

  • TransformXml Task locks config file identified in Source attribute

    - by alexhildyard
    As background: the TransformXml MSBuild task is typically invoked in a custom build step to mark up a web.config file with per-environment configuration; its flexible directives offer highly granular control over the insertion, removal, substitution and transformation of existing configuration hierarchies. For those using the TransformXML task (typically in a Web Deployment Project) I raised an issue against Visual Studio 2010, in which the file handle on the input file was not released, meaning that following transformation the source file remained locked. As a result, the best way to transform a file was first to rename it, transform it, and then copy it back, leaving the "locked" file to be freed up later.I just heard today that this has now been resolved in Visual Studio 2012 RTM. That's good news, because Web Config Transformations offer a lot. An intelligent, automated build process will swap in the relevant transform(s), making it much easier to synthesise the Developer and Build server builds. This makes for a simpler and more exemplary build process, and with the tighter coupling comes a correspondingly quicker response to Developmental change.Oh, and don't forget -- it isn't just web.configs you can transform. You can transform app.configs, or indeed any XML file that honours the task's schema and hierarchical rules.

  • Correct way to use Farseer Physics in XNA

    - by user1640602
    I am using Farseer Physics for my 2D sidescroller game and I'm not sure how to proceed with it. I currently have a Sprite class (handles nothing but graphics), a GameObject class (contains specific object info like hit points), a World object which contains the list of Bodies, and a Level object which contains all of these objects. Originally I was trying to keep track of the Sprites, GameObjects, and Bodies separately because I felt that would provide loose coupling but it quickly became a headache. So my new idea was to add a Sprite member to the GameObject class but I'm still not sure how to maintain the Bodies because they have to communicate with GameObject. Specifically, my issue is this: The position of the Body is used to draw the Sprite inside of the Level. In order to do that I would have to maintain a link between GameObjects and Bodies. Is this correct or is there a better way to architect my game? If any of this is unclear please ask and I'll try to clarify. Thank you in advance for any help.

  • How to implement behavior in a component-based game architecture?

    - by ghostonline
    I am starting to implement player and enemy AI in a game, but I am confused about how to best implement this in a component-based game architecture. Say I have a following player character that can be stationary, running and swinging a sword. A player can transit to the swing sword state from both the stationary and running state, but then the swing must be completed before the player can resume standing or running around. During the swing, the player cannot walk around. As I see it, I have two implementation approaches: Create a single AI-component containing all player logic (either decoupled from the actual component or embedded as a PlayerAIComponent). I can easily how to enforce the state restrictions without creating coupling between individual components making up the player entity. However, the AI-component cannot be broken up. If I have, for example, an enemy that can only stand and walk around or only walks around and occasionally swing a sword, I have to create new AI-components. Break the behavior up in components, each identifying a specific state. I then get a StandComponent, WalkComponent and SwingComponent. To enforce the transition rules, I have to couple each component. SwingComponent must disable StandComponent and WalkComponent for the duration of the swing. When I have an enemy that only stands around, swinging a sword occasionally, I have to make sure SwingComponent only disables WalkComponent if it is present. Although this allows for better mix-and-matching components, it can lead to a maintainability nightmare as each time a dependency is added, the existing components must be updated to play nicely with the new requirements the dependency places on the character. The ideal situation would be that a designer can build new enemies/players by dragging components into a container, without having to touch a single line of engine or script code. Although I am not sure script coding can be avoided, I want to keep it as simple as possible. Summing it all up: Should I lob all AI logic into one component or break up each logic state into separate components to create entity variants more easily?

  • How would you model an objects representing different phases of an entity life cycle?

    - by Ophir Yoktan
    I believe the scenario is common mostly in business workflows - for example: loan management the process starts with a loan application, then there's the loan offer, the 'live' loan, and maybe also finished loans. all these objects are related, and share many fields all these objects have also many fields that are unique for each entity the variety of objects maybe large, and the transformation between the may not be linear (for example: a single loan application may end up as several loans of different types) How would you model this? some options: an entity for each type, each containing the relevant fields (possibly grouping related fields as sub entities) - leads to duplication of data. an entity for each object, but instead of duplicating data, each object has a reference to it's predecessor (the loan doesn't contain the loaner details, but a reference to the loan application) - this causes coupling between the object structure, and the way it was created. if we change the loan application, it shouldn't effect the structure of the loan entity. one large entity, with fields for the whole life cycle - this can create 'mega objects' with many fields. it also doesn't work well when there's a one to many or many to many relation between the phases.

  • How to handle notifications to several partial views of the same model?

    - by Seki
    I am working on refactoring an old simulation of a Turing machine. The application uses a class that contains the state and the logic of program execution, and several panels to display the tape representation and show the state, messages, and the GUI controls (start, stop, program listing, ...). I would like to refactor it using the MVC architecture that was not used originaly: the Frame is the only way to get access to the different panels and there is also a strong coupling between the "engine" class and the GUI updates in the way of frame.displayPanel.state.setText("halted"); or frame.outputPanel.messages.append("some thing"); It looks to me that I should put the state related code into an observable model class and make the different panels observers. My problem is that the java Observable class only provides a global notification to the Observers, while I would prefer not to refresh every Observers everytime, but only when the part that specificaly observe has changed. I am thinking of implementing myself several vectors of listeners (for the state / position, for the output messages, ...) but I feel like reinventing the wheel. I though also about adding some flags that the observers could check like isNewMessageAvailable(), hasTapeMoved(), etc but it sounds also approximative design. BTW, is it ok to keep the fetch / execute loop into the model or should I move it in another place? We can think in a theorical ideal way as I am completely revamping this small application.

  • How To Restore Firefox Options To Default Without Uninstalling

    - by Gopinath
    Firefox plugins are awesome and they are the pillars for the huge success of Firefox browser. Plugins vary from simple ones like changing color scheme of the browser to powerful ones likes changing the behavior of the browser itself. Recently I installed one of the powerful Firefox plugins and played around to tweak the behavior of the browser. At the end of my half an hour play, Firefox has completely become useless and stopped rending web pages properly. To continue using Firefox I had to restore it to default settings. But I don’t like to uninstall and then install it again as it’s a time consuming process and also I’ll loose all the plugins I’m using. How did I restore the default settings in a single click? Default Settings Restore Through Safe Mode Options It’s very easy to restore default settings of Firefox with the safe mode options. All we need to do is 1.  Close all the Firefox browser windows that are open 2. Launch Firefox in safe mode 3. Choose the option Reset all user preferences to Firefox defaults 4. Click on Make Changes and Restart button. Note: When Firefox restore the default settings, it erases all the stored passwords, browser history and other settings you have done. That’s all. This excellent feature of Firefox saved me from great pain and hope it’s going to help you too. Join us on Facebook to read all our stories right inside your Facebook news feed.

  • Can't copy file with green filename, access denied

    - by Swinders
    Using Windows Explorer under XP I see some of my files have green filenames. When I try and copy one of these files I get an error reporting Access denied. The My pictures folder also appears with green text and I have a large number of photos from family holidays I don't want to loose. I need to backup these files as I'm changing laptop soon. We use SafeBoot to encryt our hard drives but I don't think this is the problem as it allows me to copy other files to removable media with no problems. Has anybody come across this before and how can I resolve this?

  • SQL SERVER – Auto Recovery File Settings in SSMS – SQL in Sixty Seconds #034 – Video

    - by pinaldave
    Every developer once in a while facing an unfortunate situation where they have not yet saved the work and their SQL Server Management Studio crashes. Well, you can minimize the loss by optimizing auto recovery settings. In this video we can see how to set the auto recovery settings. Go to SSMS >> Tools >> Options >> Environment >> AutoRecover There are two different settings: 1) Save AutoRecover Information Every Minutes This option will save the SQL Query file at certain interval. Set this option to minimum value possible to avoid loss. If you have set this value to 5, in the worst possible case, you can loose last 5 minutes of the work. 2) Keep AutoRecover Information for Days This option will preserve the AutoRecovery information for specified days. Though, I suggest in case of accident open SQL Server Management Studio right away and recover your file. Do not procrastinate this important task for future dates.

  • Jobs stuck in Print Queue on print server

    Hello, I have a Server 2003 machine acting as a print server for about 20 printers. There is 1 printer which we are having issues with and it has 104 documents in its queue. I have attempted the "Cancel All Documents" and tried to manually cancel individual documents without success. The print jobs state "Deleting - Sent to printer" under their status. It has been in this state for about 2 hours. I do not believe restarting the spool is an option without effecting the other printers and we have Hold printer for a specific non windows printing friendly application, in which I can not loose the jobs for. Any ideas on a fix? Thanks, Carl

So, please help me. I have already asked a question about how to download from my website all my pictures automatically here and I was advised to use Wget. But I don't know the very basics as to how to use it. The basics are not explained on that page. In that questioned that I asked I was even given this line: wget -r -A .jpg,.gif,.png but I don't know what I am supposed to do with it in order to get the Wget going and download all the pictures from my website. Please, help me somebody!

  • General directions on developing a server side control system for JS/Canvas Action RPG

    - by Billy Ninja
    Well, yesterday I asked on anti-cheat JS, and confirmed what I kind of already knew that it's just not possible. Now I wanna measure roughly how hard it is to implement a server side checking that is agnostic to client input, that does not mess with the game experience so much. I don't wanna waste to much resource on this matter, since it's going to be initially a single player game, that I may or would like to introduce some kind of ranking, trading system later on. I'd rather deliver better more cool game features instead. I don't wanna have to guarantee super fast server response to keep the game going lag free. I'd rather go with more loose discrete control of key variables and instances. Like store user's action on a fifo buffer on the client, and push that actions to the server gradually. I'd love to see a elegant, generic solution that I could plug into my client game logic root (not having to scatter treatments everywhere in my client js) - and have few classes on Node.js server that could handle that - without having to mirror/describe all of my game entities a second time on the server.

  • CoffeeScript Test Framework

    - by Liam McLennan
    Tonight the Brisbane Alt.NET group is doing a coding dojo. I am hoping to talk someone into pairing with me to solve the kata in CoffeeScript. CoffeeScript is an awesome language, half javascript, half ruby, that compiles to javascript. To assist with tonight’s dojo I wrote the following micro test framework for CoffeeScript: <html> <body> <div> <h2>Test Results:</h2> <p class='results' /> </div> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> <script type="text/coffeescript"> # super simple test framework test: { write: (s) -> $('.results').append(s + '<br/>') assert: (b, message...) -> test.write(if b then "pass" else "fail: " + message) tests: [] exec: () -> for t in test.tests test.write("<br/><b>$t.name</b>") t.func() } # add some tests test.tests.push { name: "First Test" func: () -> test.assert(true) } test.tests.push { name: "Another Test" func: () -> test.assert(false, "You loose") } # run them test.exec(test.tests) </script> <script type="text/javascript" src="coffee-script.js"></script> </body> </html> It’s not the prettiest, but as far as I know it is the only CoffeeScript test framework in existence. Of course, I could just use one of the javascript test frameworks but that would be no fun. To get this example to run you need the coffeescript compiler in the same directory as the page.

  • PowerDNS 3+ - Recursive queries for subdomains

    - by PDNS Troubles
    We are trying to find functionality in the PDNS 3.x that existed in PDNS < 2.9.2.5. Whereby if we have a domain in the database backend with records, if a query is unable to resolve a subdomain it would then query the recursor setup in the pdns.conf file. We have found that on Centos 6.x the rpm packages are the latest verison of pdns where by 5.x available was pdns-2.9.22-4.el5. The pdns-2.9.22-4.el5 package works as expected but when upgrading servers to Centos 6.x we loose this required functionality. pdns-backend-mysql-2.9.22-4.el5.rpm fails to install on Centos 6.x due to mysql libs that aren't availble, this is caused by an upgrade in the mysql version whereby the pdns backend mysql requires older mysql libs then what is available on centos 6.x .

  • Deleted the .AppleDouble files inside my Time Machine backups - are they still OK?

    - by Jon M
    My Ubuntu server is set up to emulate a TimeCapsule (after a very long weekend following the instructions here, here and here). My macbook pro has been backing up happily to it for a month or so now, and all seems well. The other day I was tidying up the extraneous files from my music collection on the server, got a bit loose with the find command... and ended up deleting all the .AppleDouble files underneath '/', which included the Time Machine folder. Now, Time Machine still appears to work fine, it backs up regularly, I can look through all the previous versions of my files, and they seem to restore without trouble. My question is: by deleting the .AppleDouble files, have I actually broken anything? Is the TM data still good, or should I trash it and start fresh (i.e. with a new 'day 0' full backup)?

(tags: oracle otn oracleace oow10) Andy Mulholland: Complicated or complex architecture or solutions "Enterprise architecture, and EAI middleware, is not likely to be the answer to this, instead we should be looking at provisioning through using the granularity of ‘services’ as opposed to the monolithic approach of applications.

The goal is to introduce an abstraction layer between the core processes represented by applications connected together through closed coupled middleware in defined relationship, and the loose coupled environment of services with the flexibility of orchestrations.

  • How to PERMANENTLY disable touchpad tap-to-click on Dell Inspiron/Windows 7

    - by Graham
    Hi all - my first time here, so I hope you can help. I've seen a lot of stuff on various forums (including here) about disabling the annoying "tap" function on a laptop touchpad. I learned the hard way not to de-install the driver (as the software suggests), since you then loose the Synaptic tab in the mouse control settings, and with it all means to modify the touchpad settings ... indicentally, if this happens to you, reboot in safe mode and do a restore, and the synaptic tab comes back. Not ideal, I know, but it works. Anyway, I have the most up-to-date drivers, and I can go to the Synaptics tab and can disable the tap-to-click function no problem. However, next time the machine is booted, tap-to-click is back on. It can alsways be disabled, but it's pain having to reset it every time the mchine is powered up. Is there a way to permanently disable it, once and for all? Thanks in advance, Graham

  • Converting to and from local and world 3D coordinate spaces?

    - by James Bedford
    Hey guys, I've been following a guide I found here (http://knol.google.com/k/matrices-for-3d-applications-view-transformation) on constructing a matrix that will allow me to 3D coordinates to an object's local coordinate space, and back again. I've tried to implement these two matrices using my object's look, side, up and location vectors and it seems to be working for the first three coordinates. I'm a little confused as to what I should expect for the w coordinate. Here are couple of examples from the print outs I've made of the matricies that are constructed. I'm passing a test vector of [9, 8, 14, 1] each time to see if I can convert both ways: Basic example: localize matrix: Matrix: 0.000000 -0.000000 1.000000 0.000000 0.000000 1.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 5.237297 -45.530716 11.021271 1.000000 globalize matrix: Matrix: 0.000000 0.000000 1.000000 0.000000 -0.000000 1.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 -11.021271 -45.530716 -5.237297 1.000000 test: Vector4f(9.000000, 8.000000, 14.000000, 1.000000) localTest: Vector4f(14.000000, 8.000000, 9.000000, -161.812256) worldTest: Vector4f(9.000000, 8.000000, 14.000000, -727.491455) More complicated example: localize matrix: Matrix: 0.052504 -0.000689 -0.998258 0.000000 0.052431 0.998260 0.002068 0.000000 0.997241 -0.052486 0.052486 0.000000 58.806095 2.979346 -39.396252 1.000000 globalize matrix: Matrix: 0.052504 0.052431 0.997241 0.000000 -0.000689 0.998260 -0.052486 0.000000 -0.998258 0.002068 0.052486 0.000000 -42.413120 5.975957 -56.419727 1.000000 test: Vector4f(9.000000, 8.000000, 14.000000, 1.000000) localTest: Vector4f(-13.508600, 8.486917, 9.290090, 2.542114) worldTest: Vector4f(9.000190, 7.993863, 13.990230, 102.057129) As you can see in the more complicated example, the coordinates after converting both ways loose some precision, but this isn't a problem. I'm just wondering how I should deal with the last (w) coordinate? Should I just set it to 1 after performing the matrix multiplication, or does it look like I've done something wrong? Thanks in advance for your help!
