• Requirement, architecture data capture tool

  - by Deno

  Are there any tools available for the following use case: I am planning to write a complex application and now I just know about the basic functional requirments. I am refining the functionality with more and more details. I am also writing down how to implement this in software architecture perspective. I am in a situation where there are multiple ways implement a certain functionality and based on the selected approach, other parts of the program will also change. At this moment, I don't want to decide on the approach to use, I just want to list down all the options, present to a wider audience and get it finalized. Are there any standard software tools to do this? I know I can use MS excel or some mind mapper tools, but just thinking of some standard tools (not just for programmers, but for managers and other) availability Thanks, Den

• Is there a correlation between complexity and reachability?

  - by Saladin Akara

  I've been studying cyclomatic complexity (McCabe) and reachability of software at uni recently. Today my lecturer said that there's no correlation between the two metrics, but is this really the case? I'd think there would definitely be some correlation, as less complex programs (from the scant few we've looked at) seem to have 'better' results in terms of reachability. Does anyone know of any attempt to look at the two metrics together, and if not, what would be a good place to find data on both complexity and reachability for a large(ish) number of programs? (As clarification, this isn't a homework question. Also, if I've put this in the wrong place, let me know.)

• client website compromised, found a strange .php file. any ideas?

  - by Kevin Strong

  I do support work for a web development company and I found a suspicious file today on the website of one of our clients called "hope.php" which contained several eval(gzuncompress(base64_decode('....'))) commands (which on a site like this, usually indicates that they've been hacked). Searching for the compromised site on google, we got a bunch of results which link to hope.php with various query strings that seem to generate different groups of seo terms like so: (the second result from the top is legitimate, all the rest are not) Here is the source of "hope.php": http://pastebin.com/7Ss4NjfA And here is the decoded version I got by replacing the eval()s with echo(): http://pastebin.com/m31Ys7q5 Any ideas where this came from or what it is doing? I've of course already removed the file from the server, but I've never seen code like this so I'm rather curious as to its origin. Where could I go to find more info about something like this?

• Is possible to write too many asserts?

  - by Lex Fridman

  I am a big fan of writing assert checks in C++ code as a way to catch cases during development that cannot possibly happen but do happen because of logic bugs in my program. This is a good practice in general. However, I've noticed that some functions I write (which are part of a complex class) have 5+ asserts which feels like it could potentially be a bad programming practice, in terms of readability and maintainability. I think it's still great, as each one requires me to think about pre- and post-conditions of functions and they really do help catch bugs. However, I just wanted to put this out there to ask if there is a better paradigms for catching logic errors in cases when a large number of checks is necessary.

• What library should I use for 2D Geometry? [closed]

  - by Luka

  I've been working on a 2D game in java, but found that java just didn't cut it for me and had forced me to a lot of bad design choices, so I've decided to port all my work to c++. The main reason I've decided change to c++ is that i had reached a point where i had 3 geometry libraries (the native, one from the game engine and one to handle "complex" polygons), none of witch worked very well together and i couldn't keep track of them. I'm new to c++, but i know all the basics. My question is, what would be a good geometry library to use, ideally it should be able to handle integer and decimal data types, have point, line, and polygon classes witch are able to check for intersection and contains. Thanks in advance, Luka

• How should UI layer pass user input to BL layer?

  - by BornToCode

  I'm building an n-tier application, I have UI, BL, DAL & Entities (built from POCO) projects. (All projects have a reference to the Entities). My question is - how should I pass user input from the UI to the BL, as a bunch of strings passed to the BL method and the BL will build the object from the parameters, or should I build the objects inside the UI submit_function and send objects as parameters? EDIT: I wrote n-tier application, but what I actually meant was just layers.

• How to generate "language-safe" UUIDs?

  - by HappyDeveloper

  I always wanted to use randomly generated strings for my resources' IDs, so I could have shorter URLs like this: /user/4jz0k1 But I never did, because I was worried about the random string generation creating actual words, eg: /user/f*cker. This brings two problems: it might be confusing or even offensive for users, and it could mess with the SEO too. Then I thought all I had to do was to set up a fixed pattern like adding a number every 2 letters. I was very happy with my 'generate_safe_uuid' method, but then I realized it was only better for SEO, and worse for users, because it increased the ratio of actual words being generated, eg: /user/g4yd1ck5 Now I'm thinking I could create a method 'replace_numbers_with_letters', and check that it haven't formed any words against a dictionary or something. Any other ideas? ps. As I write this, I also realized that checking for words in more than one language (eg: english and french, spanish, etc) would be a mess, and I'm starting to love numbers-only IDs again.

• Recommended flexible website solution?

  - by Omega

  My site has a MyBB forums installation, and that is pretty much all I need. Forums. However, I need a homepage and a couple other static pages, for showing relevant information, links, etc. I don't need something fancy, all I need is something very flexible regarding theme and style editing, and just a couple simple modules, like public polls. That's all. I am very graphical, and I am looking for something to let me edit pretty much every aspect of the site. These are static pages, mainly, so I don't need something very complex. Some people tell me to use Dreamweaver, but quite honestly, that is not what I am looking for, even thought it does offer a lot of flexibility. I want something like, you know, Drupal or.. some other simple, deeply-editable in terms of graphics and style web platform. What would you recommend to me? Thank you.

• I'm having trouble understanding these exercises wording.

  - by KasHKoW

  Exercise 1-20. Write a program detab that replaces tabs in the input with the proper number of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every n columns. Should n be a variable or a symbolic parameter? Exercise 1-21. Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab. When either a tab or a single blank would suffice to reach a tab stop, which should be given preference? could you paraphrase these for me. thanks

• when should a database table be broken into multiple tables with relations?

  - by GSto

  I have an application that needs to store client data, and part of that is some data about their employer as well. Assuming that a client can only have one employer, and that the chance of people having identical employer data is slim to none, which schema would make more sense to use? Schema 1 Client Table: ------------------- id int name varchar(255), email varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16), employer_name varchar(255), employer_phone varchar(255), employer_address varchar(255), employer_city varchar(255), employer_state char(2), employer_zip varchar(16) **Schema 2** Client Table ------------------ id int name varchar(255), email varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16), Employer Table --------------------- id int name varchar(255), phone varchar(255), address varchar(255), city varchar(255), state char(2), zip varchar(16) patient_id int Part of me thinks that since are clearly two different 'objects' in the real world, seperating them out into two different tables makes sense. However, since a client will always have an employer, I'm also not seeing any real benefits to seperating them out, and it would make querying data about clients more complex. Is there any benefit / reason for creating two tables in a situation like this one instead of one?

• How will this affect my SEO ranking?

  - by dunc

  I run a fishkeeping website based on a WordPress (PHP) CMS. I've recently put a fairly complex "filter" into place which searches my content for mentions of fish species profiles and turns them into an active link. For example, asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and A. panduro and Apistogramma panduro ...becomes asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and <a href="/?p=1703" class="link_species">A. panduro</a> and <a href="/?p=1703" class="link_species">Apistogramma panduro</a> On the rest of my website, the species are linked with pretty URLs such as /species/apistogramma-panduro/ but due to the way this filter works, the only information I can get access to is the idof the post. As such, I'm using /?p=1703 or whatever the ID is. What I'd like to know is: how much will this affect my SEO rating/ranking? Will it be detrimental if I don't rewrite the function? Thanks in advance,

• Good technologies for developing a modular server component in .net?

  - by nubbers

  I am using WPF, Prism and Unity to develop the user interface for a .net application. The UI will run from a PC, but I also need to develop a separate complex server component that will provide services to the PC component via WCF. Prism and Unity have proved to be of great value in creating a modular application, at least as far as the user interface is concerned. I would also like to make the server component modular, but I cannot find anywhere what techniques, patterns and technologies are suitable. I have considered: Unity or one of the other DI containers Selected parts of Prism, such as modules and events Are these suitable for developing a modular server component? Or are these UI technologies only and should I be looking at something completely different?

• What are the best patterns/designs for stateful API development?

  - by Svante

  I am about to implement a API for my TCP/IP server written in Java. Right now I have a temporary method that takes a String, executes a command based on the String and returns a String basically like the following. public void communicate(BufferedReader in, PrintWriter out) { while(true) { out.println(handleCommand(in.readLine())); } } private String handleCommand(String command) { if (command.equals("command1") { // do stuff return "Command 1 executed"; } else if (command.equals("command2") { // do some other stuff return "Command 2 executed"; } } I really want to do something more extensible, smarter and stateful, so I could handle more complex and stateful commands and without the method/class getting bloated. How would you start? Suggestions, ideas, or links for further reading are very welcome.

• How to determine the right amount of up front design?

  - by Gian

  Software developers occasionally are called upon to write fairly complex bits of software under tight deadlines. Often, it seems like the quickest thing to do is to simply start coding, and solve the problems as they arise. However, this approach can come back to bite you—often costing time or money in the long run! How do we determine the right amount of up front design work? If your work environment actively discourages you from thinking about things up front, how do you handle that? How can we manage risk if we eschew up-front thinking (by choice or under duress) and figure out the problems as they arise? Does the amount of up front design depend entirely on the size or complexity of the task, or is it based on something else?

• From the Coalface - 4 - Getting a connection string

  - by TATWORTH

  Creating a connection string by hand is quite difficult, however you create a connection string as follows: 1) Create an empty text file in windows explorer and rename it to X.UDL 2) Double click on it and the datalink provider dialog will appear. 3) Select the provider tab. Find the provider for your data access method and click next. 4) Select your source  5) Test the connection and save it. 6) Open X.UDL with a text editor to see your connections string. You can also look at http://www.connectionstrings.com/ for examples of connection strings.

• Data for animation

  - by saadtaame

  Say you are using C/SDL for a 2D game project. It's often the case that people use a structure to represent a frame in an animation. The struct consists of an image and how much time the frame is supposed to be visible. Is this data sufficient to represent somewhat complex animatio? Is it a good idea to separate animation management code and animation data? Can somebody provide a link to animations tutorials that store animations in a file and retrieve them when needed. I read this in a book (AI game programming wisdom) but would like to see a real implementation.

• Is OOP becoming easier or harder?

  - by tunmise fasipe

  When the concepts of Object Oriented Programming were introduced to programmers years back it looks interesting and programming was cleaner. OOP was like this Stock stock = new Stock(); stock.addItem(item); stock.removeItem(item); That was easier to understand with self-descriptive name. But now OOP, with pattern like Data Transfer Objects (or Value Objects), Repository, Dependency Injection etc, has become more complex. To achieve the above you may have to create several classes (e.g. abstract, factory, DAO etc) and Implement several interfaces Note: I am not against best practices that makes Collaboration, Testing and Integration easier

• Vanilla forum personal journal tool

  - by user16648

  I am developing a forum for a research project, i am using Vanilla forum (though i am not tied to this yet). Another feature of this site will be a personal journal/diary/blog. Only the user and administrators will have access to the journal. The journal does not need any advanced features. Does anybody have any suggestions on software/script that could easily be integrated with Vanilla forum for this purpose? My first thought was using Wordpress but it is a bit to complex to adminstrate as the site is meant to be simple. And i dont really see how it can be intregrated easily the way i want it.

• SEO Impact of using Responsive Design and the serving of different content on the same URL

  - by bmenekl

  We are currently working on redesigning our site and making it responsive. It is a search intensive site with complex functionality, a lot of search filters and a lot of content. Our mobile versions of certain pages need to hide some functionality (i.e. search filters) that exists in the desktop version and/or content (mainly blocks of text that are not necessary or are increasing page load in mobile devices). My questions is this: does the situation of having the same URL (responsive site) serving slightly different content (text and/or search filters) for certain pages in different devices affect our SEO (SERPs or otherwise)?
