• TTS on App Engine

  - by yati sagade

  I have written a small front-end to the Festival TTS system using Python/Django. I wish to deploy it on the Google App Engine cloud. A few questions: My application uses the Festival app 'text2wave'. Will is work on the cloud? I have used Python primitives like subprocess.call() to invoke the aforementioned program. Will that work? If your answer to any or both of (1) and (2) is no, is there a free api on the web that I can use (from the appengine)? I read somewhere about placing calls from Phono to a Voxeo backend, but I'm not sure what that means. I am aware of the Google Translate extension that allows translation using an HTTP GET (REST) request, but here the text is limited to 100 chars. Bad. Plus, they may take it down any point of time.

• How to render RSS feed in a desktop RSS reader?

  - by Thiago Moraes

  Consider one feed like this: http://feeds.feedburner.com/codinghorror It has the entire content inside the description tag of the feed, so you don't need to access the website to read the post. Now I have the problem of creating an interface for a feed like this on a desktop client. What's the best way to render the text in a pleasant way to the user? My first thought was to parse the entire HTML as if I was a web browser, but that looks really hard to do in a satisfying way. Are there any better (faster) alternatives? Rephrasing: how a desktop rss client such as feeddamon parses the input to display it nicely? Does it have a web browser inside it?

• C-Objective Function

  - by nimbus

  I'm unsure about how to make MWE with C-Obective, so if you need anything else let me know. I am trying running through a tutorial on building an iPhone app and have gotten stuck defining a function. I keep getting an error message saying "use of undeclared indentifer." However I believe I have initiated the function. In the view controller I have: if (scrollAmount > 0) { moveViewUp = YES; [scrollTheView:YES]; } else{ moveViewUp = NO; } with the function under it - (void)scrollTheView:(BOOL)movedUp { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; CGRect rect = self.view.frame; if (movedUp){ rect.origin.y -= scrollAmount; } else { rect.origin.y += scrollAmount; } self.view.frame = rect; [UIView commitAnimations]; } I have initiated the function in the header file (that I have imported). - (void)scrollTheView:(BOOL)movedUp; Any help would be appreciated, thank you in advanced

• Creating a layer of abstraction over the ORM layer

  - by Daok

  I believe that if you have your repositories use an ORM that it's already enough abstracted from the database. However, where I am working now, someone believe that we should have a layer that abstract the ORM in case that we would like to change the ORM later. Is it really necessary or it's simply a lot of over head to create a layer that will work on many ORM? Edit Just to give more detail: We have POCO class and Entity Class that are mapped with AutoMapper. Entity class are used by the Repository layer. The repository layer then use the additional layer of abstraction to communicate with Entity Framework. The business layer has in no way a direct access to Entity Framework. Even without the additional layer of abstraction over the ORM, this one need to use the service layer that user the repository layer. In both case, the business layer is totally separated from the ORM. The main argument is to be able to change ORM in the future. Since it's really localized inside the Repository layer, to me, it's already well separated and I do not see why an additional layer of abstraction is required to have a "quality" code.

• Are SQL Injection vulnerabilities in a PHP application acceptable if mod_security is enabled?

  - by Austin Smith

  I've been asked to audit a PHP application. No framework, no router, no model. Pure PHP. Few shared functions. HTML, CSS, and JS all mixed together. I've discovered numerous places where SQL injection would be easily possible. There are other problems with the application (XSS vulnerabilities, rampant inline CSS, code copy-pasted everywhere) but this is the biggest. Sometimes they escape inputs, not using a prepared query or even mysql_real_escape_string(), mind you, but using addslashes(). Often, though, their queries look exactly like this (pasted from their code but with columns and variable names changed): $user = mysql_query("select * from profile where profile_id='".$_REQUEST["profile_id"]."'"); The developers in question claimed that they were unable to hack their application. I tried, and found mod_security to be enabled, resulting in HTTP 406 for some obvious SQL injection attacks. I believe there to be sophisticated workarounds for mod_security, but I don't have time to chase them down. They claim that this is a "conceptual" matter and not a "practical" one since the application can't easily be hacked. Their internal auditor agreed that there were problems, but emphasized the conceptual nature of the issues. They also use this conceptual/practical argument to defend against inline CSS and JS, absence of code organization, XSS vulnerabilities, and massive amounts of repetition. My client (rightly so, perhaps) just wants this to go away so they can launch their product. The site works. You can log in, do what you need to do, and things are visibly functional, if slow. SQL Injection would indeed be hard to do, given mod_security. Further, their talk of "conceptual vs. practical" is rhetorically brilliant, considering that my client doesn't understand web application security. I worry that they've succeeded in making me sound like an angry puritan. In many ways, this is a problem of politics, not technology, but I am at a loss. As a developer, I want to tell them to toss the whole project and start over with a new team, but I face a strong defense from the team that built it and a client who really needs to ship their product. Is my position here too harsh? Even if they fix the SQL Injection and XSS problems can I ever endorse the release of an unmaintainable tangle of spaghetti code?

• What platform to use for browser based turn based strategy game

  - by sunwukung

  I want to write a browser based strategy game that can be played by two players in separate locations. The game itself is predominantly turn based. To that end, I want to determine the correct platform on which to build this game. To prevent gamers "gaming" the system, the business logic needs to reside in the server. I could arguably use AJAX for a large part of the games functionality, but at two key points in the game loop, the opposing player can "counter" the current players move. In addition, when it's time for the players to swap, AJAX polling is likely to fall short, so it's starting to look like WebSockets is going to be a requirement to pull this off smoothly. So, the remaining question is regarding the back end. I'd kinda like to build this in Python/Flask - but this is primarily out of wanting to tackle a project with that language, not neccessarily because it's the appropriate tool for the job. The next most likely candidate has got to be NodeJS given it's (apparently) tighter integration with the WebSockets protocol. My question, then, is regarding the best platform on which to pursue this objective.

• Understanding the problem when things break in production

  - by bitcycle

  Scenario: You push to production The push broke multiple things That same build did not break qa or dev As a developer, you don't have prod access. There is lots of pressure from above to get things working agian. Specifics: PHP/MVC application that is API-driven in Zend. Deployed to a few servers. My question: While investigating, lets say I have a hunch that something is wrong. But, I don't know for sure. And, of course, I can't test things in production. If I have a suggested fix based on that hunch, would it be wise to try and apply it and see if it works, before understanding what the problem is?

• I'm a CS student, and honestly I don't understand Knuth's books..

  - by Raymond Ho

  I stumbled this quote from Bill Gates: "You should definitely send me a resume if you can read the whole thing." He was talking about The Art of Programming books.. So I was pretty curious and want to read it all but honestly, I don't understand it at all.. I'm really not that highly intellectual being.. So this should be the reason why I can't understand it, but I am eager to learn.. I'm currently reading volume 1 about fundamental algo.. So is there any books out there that are friendly to novice/slow people like me? So I can build up myself and hopefully in the future I can read Knuth's book at ease..

• How to avoid code duplication for a system which has logic that may change year wise?

  - by aravind

  What would be the way to design a system which has logic that may change year wise? There is an application which conducts online exams. There are five questions for a particular subject. The questions may (or may not) change year wise. As per my current design, the questions in database are stored year wise. There are some year specific code logic as well. In order to enable the application for another year, the year specific database records and code will be copied or duplicated. How to avoid this code duplication?

• Storing Attendance Data in database

  - by Ali Abbas

  So i have to store daily attendance of employees of my organisation from my application . The part where I need some help is, the efficient way to store attendance data. After some research and brain storming I came up with some approaches . Could you point me out which one is the best and any unobvious ill effects of the mentioned approaches. The approaches are as follows Create a single table for whole organisation and store empid,date,presentstatus as a row for every employee everyday. Create a single table for whole organisation and store a single row for each day with a comma delimited string of empids which are absent. I will generate the string on my application. Create different tables for each department and follow the 1 method. Please share your views and do mention any other good methods

• Lvalue required error [migrated]

  - by ankur.trapasiya

  While working with pointers i wrote the following code, int main() { int a[]={10,20,30,40,50}; int i; for(i=0;i<5;i++) { printf("\n%d",*a); a++; } return 0; } Now as per my understanding array name itself is an address in c and the pointer arithmetic done is here is correct as per my knowledge. But when i try to run the code it is giving me "Lvalue Required" error. So what is the exact reason for occuring Lvalue required error because before this also i have come across situations where this error is there. Secondly why the arithmetic on the pointer is not legal here in this case?

• What version control system can manage all aspects?

  - by Andy Canfield

  A few months ago I dug into Subversion and GIT and was disappointed. They handle SOURCE CODE fine but not other aspects. For example, a web site under version control needs to manage file/directory ownership, file/directory read & write access, Access Control Lists, timestamps, database contents. and external links. Is there a version control system that can do as perfect a reversion as reloading from a month-old backup?

• Software development life cycle in the industry

  - by jiewmeng

  I am taking a module called "Requirements Analysis & Design" in a local university. Common module, I'd say (on software development life cycle (SDLC) and UML). But there is a lot of things I wonder if they are actually (strictly) practiced in the industry. For example, will a domain class diagram, an not anything extra (from design class), be strictly the output from Analysis or Discovery phase? I'm sure many times you will think a bit about the technical implementation too? Else you might end up with a design class diagram later that is very different from the original domain class diagram? I also find it hard to remember what diagrams are from Initiation, Discovery, Design etc etc. Plus these phases vary from SDLC to SDLC, I believe? So I usually will create a diagram when I think will be useful. Is it the wrong way?

• How abstract should you get with BDD

  - by Newton

  I was writing some tests in Gherkin (using Cucumber/Specflow). I was wondering how abstract should I get with my tests. In order to not make this open-ended, which of the following statements is better for BDD: Given I am logged in with email [email protected] and password 12345 When I do something Then something happens as opposed to Given I am logged in as the Administrator When I do something Then something happens The reason I am confused is because 1 is more based on the behaviour (filing in email and password) and 2 is easier to process and write the tests.

• Dual Inspection / Four Eyes Principle

  - by Ralf

  I have the requirement to implement some kind of dual inspection or four-eyes principle as a feature of my software, meaning that every change of an object done by user A has to be checked by user B. A trivial example would be a publishing system where an author writes an article and another has to proofread it before it is published. I am a little bit surprised that you find nearly nothing about it on the net. No patterns, no libraries (besides cibet), no workflow solutions etc. Is this requirement really so uncommon? Or am I searching for the wrong terms? I am not looking for a specific solution. More for a pattern or best practice approach. Update: the above example is really trivial. Let's add some more complexity to it. The article has been published, but it now needs an update. Putting the article offline for the update is not an option, but the update has to be proof read, too.

• As a programmer how do I plan to learn new things in my spare time

  - by priyank patel

  I am a Asp.Net/C# developer, I develop few projects in my spare time. I try to utilize my time as much as I can. I have been working for past 7 months. Suddenly these days I am a bit worried about learning the new stuff that is there for me as a programmer. I develop in my spare time so I don't get enough time to read books or blogs. So my question to some of you guys is how should I plan to learn new things, should I at least dedicate two-three evenings for new stuff, maybe ebooks while travelling is a good option too. How do you people plan to learn,should I also start to develop with whatever I learnt? As far as learning is concerned, should I just pick up the basics and then implement it or I should seek deeper understanding of the subject?

• When using membership provider, do you use the user ID or the username?

  - by Chris

  I've come across this is in a couple of different applications that I've worked on. They all used the ASP.NET Membership Provider for user accounts and controlling access to certain areas, but when we've gotten down into the code I've noticed that in one we're passing around the string based user name, like "Ralph Waters", or we're passing around the Guid based user ID from the membership table. Now both seem to work. You can make methods which get by username, or get by user ID, but both have felt somewhat "funny". When you pass a string like "Ralph Waters" you're passing essentially two separate words that make up a unique identifier. And with a Guid, you're passing around a string/number combination which can be cast and made unique. So my question is this; when using Membership Provider, which do you use, the username or the user ID to get back to the user? Thanks all!

• Is there a more intelligent way to do this besides a long chain of if statements or switch?

  - by Harrison Nguyen

  I'm implementing an IRC bot that receives a message and I'm checking that message to determine which functions to call. Is there a more clever way of doing this? It seems like it'd quickly get out of hand after I got up to like 20 commands. Perhaps there's a better way to abstract this? public void onMessage(String channel, String sender, String login, String hostname, String message){ if (message.equalsIgnoreCase(".np")){ // TODO: Use Last.fm API to find the now playing } else if (message.toLowerCase().startsWith(".register")) { cmd.registerLastNick(channel, sender, message); } else if (message.toLowerCase().startsWith("give us a countdown")) { cmd.countdown(channel, message); } else if (message.toLowerCase().startsWith("remember am routine")) { cmd.updateAmRoutine(channel, message, sender); } }

• Diagram to show code responsibility

  - by Mike Samuel

  Does anyone know how to visually diagram the ways in which the flow of control in code passes between code produced by different groups and how that affects the amount of code that needs to be carefully written/reviewed/tested for system properties to hold? What I am trying to help people visualize are arguments of the form: For property P to hold, nd developers have to write application code, Ca, without certain kinds of errors, and nm maintainers have to make sure that the code continues to not have these kinds of errors over the project lifetime. We could reduce the error rate by educating nd developers and nm maintainers. For us to be confident that the property holds, ns specialists still need to test or check |Ca| lines of code and continue to test/check the changes by nm maintainers. Alternatively, we could be confident that P holds if all code paths that could violate P went through tool code, Ct, written by our specialists. In our case, test suites alone cannot give confidence that P holdsnd » nsnm ns|Ca| » |Ct| so writing and maintaining Ct is economical, frees up our developers to worry about other things, and reduces the ongoing education commitment by our specialists. or those conditions do not hold, so focusing on education and testing is preferable. Example 1 As a concrete example, suppose we want to ensure that our web-service only produces valid JSON output. Our web-service provides several query and mutation operators that can be composed in interesting ways. We could try to educate everyone who maintains those operations about the JSON syntax, the importance of conformance, and libraries available so that when they write to an output buffer, every possible sequence of appends results in syntactically valid JSON. Alternatively, we don't expose an output stream handle to application code, and instead expose a JSON sink so that every code path that writes a response is channeled through a JSON sink that is written and maintained by a specialist who knows JSON syntax and can use well-written libraries to produce only valid output. Example 2 We need to make sure that a service that receives a URL from an untrusted source and tries to fetch its content does not end up revealing sensitive files from the file-system, like file:///etc/passwd. If there is a single standard way that any developer familiar with the application language's libraries would use to fetch URLs, which has file-system access turned off by default, then simply educating developers about the standard mechanism, and testing that file probing fails for some inputs, will probably be sufficient.

• Design Application to "Actively" Invite Users (pretend they have privileges)

  - by user3086451

  I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

• Proposal for a new position at work

  - by Seth P.

  I have an idea at work for a new Product Manager position at our office. I work with several developers, and it would be helpful to have someone working in a type of "Scrum Master" capacity, dividing out assignments and making sure they get complete. This position does not currently exist, however I feel that I have enough evidence to indicate that it be very helpful for our business. What is the best way to present this proposal to my boss? Is there a specific template that you know of for new position? It should be able to describe the qualification for the position, their responsibilities, and what metrics we would use to measure them. Thanks. UPDATE++++ With Anna's suggestion, I gave more details about this specific position. However, I would ideally like the most generic way to present a new position to my boss.

• Flash messages in ASP.NET MVC without sessions

  - by Fernando Correia

  I'm developing a web application for Windows Azure using ASP.NET MVC 4. I would like to enforce one restriction in the architecture: do not use Session. To achieve availability on Azure, and since there is no sticky sessions, I would need to store the session data in some central service, probably either SQL Azure or the Caching Service. I would rather avoid sessions on the SQL database to avoid the increased latency, and the caching service on Azure is very expensive for the ammount of memory offered. On the other hand, I would like to have the ability to easily pass Flash-style messages among redirects. TempData is the recommended way to do this, but by default it uses the session object. So I would like to know: Is there an alternative way to use TempData that doesn't require sessions or shared data between servers? Cookies perhaps? Is there a better alternative I'm overlooking?

• Is it customary to write Java domain objects / data transfer objects with public member variables on mobile platforms?

  - by Sean Mickey

  We performed a code review recently of mobile application Java code that was developed by an outside contractor and noticed that all of the domain objects / data transfer objects are written in this style: public class Category { public String name; public int id; public String description; public int parentId; } public class EmergencyContact { public long id; public RelationshipType relationshipType; public String medicalProviderType; public Contact contact; public String otherPhone; public String notes; public PersonName personName; } Of course, these members are then accessed directly everywhere else in the code. When we asked about this, the developers told us that this is a customary performance enhancement design pattern that is used on mobile platforms, because mobile devices are resource-limited environments. It doesn't seem to make sense; accessing private members via public getters/setters doesn't seem like it could add much overhead. And the added benefits of encapsulation seem to outweigh the benefits of this coding style. Is this generally true? Is this something that is normally done on mobile platforms for the reasons given above? All feedback welcome and appreciated -

• Are #regions an antipattern or code smell?

  - by Craig

  In C# code it allows the #region/#endregion keywords to made areas of code collapsible in the editor. Whenever I am doing this though I find it is to hide large chunks of code that could probably be refactored into other classes or methods. For example I have seen methods that contain 500 lines of code with 3 or 4 regions just to make it manageable. So is judicious use of regions a sign of trouble? It seems to be to me.

• What is the oldest living piece of unaltered production code? [closed]

  - by user1598390

  It's come to my mind that parts of the code in, say, Unix, has maybe passed unaltered from one version or flavor into another. Maybe some pieces of the source code of the ls command is the same, unaltered, than was written years ago. Have any of you read or learn about this ? What would be the oldest living piece of unaltered production code still running, passing from version through version of a program or system ? Will the code we write outlive us for decades ?
