• How to plan/manage multi-platform (mobile) products?

  - by PhD

  Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

• Storing Tiled Level Data in J2ME game

  - by Alex

  I'm developing a J2ME game which uses tiled backgrounds for the levels. My question is how do I store this tile information in my game. At the moment it is stored as an array; with each number representing a different tile from the tile-sheet. This works well enough, however I don't like the fact that it is 'hard-coded' into the game because (at least in my opinion) it is harder to edit the levels, or design new ones. I was also thinking that it would be difficult if you wanted to add a 'level pack', I'm not sure on how this would be achieved though; it's not something I was planning on doing, I'm just curious. I was wondering if there was a way I could store level data in some external file and then load this in to the game. The problem is I don't know what the limitations are for J2ME regarding file I/O, can it read in any file like Java? I am aware of the RMS, but from my experience I don't think this would work (unless I am mistaken). Also, would loading the data in this way be too big a performance hit? Or is there another way I can achieve what I am trying to do. As I said, the way I have it at the moment works fine, and if this is the only viable option then it will suffice.

• How to tackle an experienced C# Programmer?

  - by nandu.com

  I am a noob in c# and asp.net developing. I have spent 6 months in design and another 6 in sql and asp.net programming. I just know the basics of asp.net and C#. I was programming as per the instruction of my tech leads and all good things changed in a day. :( All my tech leads (2+ experienced) left the company complaining about salary. And instead of those, company has recruited a 5+ experienced programmer cum tech lead (who is very strict), he is expecting me to code anything he says. Previous seniors of me, would say 'use ajax for this, use query for this instead of coding' and so on. I will do it exactly. I am not experienced enough to perform it myself. Now I am in a dilemma. I want to stay in the company and learn some more, but this new tech lead is expecting me to learn everything myself (he is telling me to learn jquery, javascript menus, session and chart in .Net, and so on and do things myself without asking him anything...I mean anything) :(((( PLease suggest to me some good tips to handle him. I think all programmers world wide would have faced a similar problem atleast once in the big programming life. So please..help .. 911

• Learning a new concept - write from scratch or use frameworks?

  - by Stu

  I have recently been trying to learn about MVVM and all of the associated concepts such as repositories, mediators, data access. I made a decision that I would not use any frameworks for this so that I could gain a better understanding of how everything worked. I’m beginning to wonder if that was the best idea because I have hit some problems which I am not able to solve, even with the help of Stack Overflow! Writing from scratch I still feel that you have a much better understanding of something when you have been in the guts of it than if you were at a higher level. The other side of that coin is that you are in the guts of something that you don't fully understand which will lead to bad design decisions. This then makes it hard to get help because you will create unusual scenarios which are less likely to occur when you working within the confines of a framework. I have found that there are plenty of tutorials on the basics of a concept but very few that take you all the way from novice to expert. Maybe I should be looking at a book for this? Using frameworks The biggest motivation for me to use frameworks is that they are much more likely to be used in the workplace than a custom rolled solution. This can be quite a benefit when starting a new job if it's one less thing you have to learn. I feel that there is much better support for a framework than a custom solution which makes sense; many more people are using the framework than the solution that you created. The level of help is much wider as well, from basic questions to really specific, detailed questions. I would be interested to hear other people's views on this. When you are learning something new, should you/do you use frameworks or not? Why? If it's a combination of both, when do you stop one and move on to the other?

• how to architect this to make it unit testable

  - by SOfanatic

  I'm currently working on a project where I'm receiving an object via web service (WSDL). The overall process is the following: Receive object - add/delete/update parts (or all) of it - and return the object with the changes made. The thing is that sometimes these changes are complicated and there is some logic involved, other databases, other web services, etc. so to facilitate this I'm creating a custom object that mimics the original one but has some enhanced functionality to make some things easier. So I'm trying to have this process: Receive original object - convert/copy it to custom object - add/delete/update - convert/copy it back to original object - return original object. Example: public class Row { public List<Field> Fields { get; set; } public string RowId { get; set; } public Row() { this.Fields = new List<Field>(); } } public class Field { public string Number { get; set; } public string Value { get; set; } } So for example, one of the "actions" to perform on this would be to find all Fields in a Row that match a Value equal to something, and update them with some other value. I have a CustomRow class that represents the Row class, how can I make this class unit testable? Do I have to create an interface ICustomRow to mock it in the unit test? If one of the actions is to sum all of the Values in the Fields that have a Number equal to 10, like this function, how can design the custom class to facilitate unit tests. Sample function: public int Sum(FieldNumber number) { return row.Fields.Where(x => x.FieldNumber.Equals(number)).Sum(x => x.FieldValue); } Am I approaching this the wrong way?

• RESTful applications logic and cross resource operations

  - by Gaz_Edge

  I have an RESTful api that allows my users to receive enquiries about their business e.g. 'I would like to book service x on date y. Is this available?'. The api saves this information as a resource to the following URI users/{userId}/enquiries/{enquiryId} The information shown when this resource is retrieved are the standard sort of things you'd expect from an enquiry - email, first_name, last_name, address, message The api also allows customers to be created for a user. The customer has a login and password and also a profile. The following URIs expose these two resources PUT users/{userId}/customers/{customerId} PUT users/{userId}/customers/{customerId}/profile The problem I am having is that I would like to have the ability to allow users to create a customer from an enquiry. For example, the user is able to offer their service on the date requested and will then want to setup a customer with login details etc to allow them to manage the rest of the process. The obvious answer would be to use a URI like users/{userId}/enquiries/{enquiryId}/convert-to-client The problem with this is is that it somewhat goes against a lot of what I've been reading about how to implement REST (specifically from the book Restful Web Services which suggests that URIs should point to resources not operations on resources). The other option would be to get the client application (i.e. the code that calls the api) to handle some of this application logic. This doesn't quite feel right to me. I have implemented in my design that the client app is fairly dumb. It knows just enough to display the results from the API, and does not contain any application logic. Would be great to hear what others views are on the best way of setting this up Am I wrong to have no application logic in the client app? How would I perform this operation purely in the REST api?

• O'reilly certification in PHP worth it?

  - by editzombie

  I asked this question over on stack overflow but I didn't realise it wasn't really the place for not so technical questions. I've seen quite a few related threads on this forum so I thought I'd try and get some feedback here: This is my first time asking a question on this forum, though I´ve read it a lot. I apologise if this is repeating a thread. I´m interested in getting into web development. I am a video editor by trade but living in Spain the way things are at the moment its very difficult to find work. I have some very basic knowledge of HTML and CSS and a little bit of flash and have designed a few little personal websites myself. I also worked for a online marketing production company where I worked a little on blog design in Blogger amongst other social media. So thats my background, but I´m trying to expand my skills and get into web development as a career or in general part of my skill base, I was thinking particularly about PHP/MySQL. I have worked a little on some of the Lynda.com tutorials and have invested in a book (Sams Teach Yourself PHP, MySQL and Apache). I´m still finding it very difficult to progress. I know I should really try some practice projects (any reccomendations would be welcome). But I was also thinking about doing one of the O´Reilly certification courses and was wondering whether it would be worthwhile for a noob like me. I hear that the courses are associated with an American University which I guess gives it more clout. Any other thoughts you guys have about how to make progress in learning web development would be fantasic. Thanks in advance.

• Why can't non-admin users install software?

  - by fiftyeight

  This is probably something I don't understand since I am used to Windows and am only starting out with Ubuntu. I know that software in linux comes in packages what I don't understand is why can't non-admin users install software. I mean, every application is run by a specific user, and that user will only be able to run that applciation with his privilages, so if he has no admin privileges, the application also won't be able to access unauthorized directories etc. I want most of the time to work on my PC with a non-admin user since it seems more safe to me, most of the time I have no need for admin privileges. and even though I know viruses in linux are uncommon I still think the best practice is to work on the computer in a state that you yourself can't make any changes to important files, that way viruses also can't harm any important files, but I need to install software for programming and web-design etc. and first of all I don't want to switch users all the time. But also it sounds safer to me that everything being done on the PC will be done through the non-admin user. I'll be glad to know what misunderstanding I have here, cause something here doesn't sound right.

• Testing a codebase with sequential cohesion

  - by iveqy

  I've this really simple program written in C with ncurses that's basically a front-end to sqlite3. I would like to implement TDD to continue the development and have found a nice C unit framework for this. However I'm totally stuck on how to implement it. Take this case for example: A user types a letter 'l' that is captured by ncurses getch(), and then an sqlite3 query is run that for every row calls a callback function. This callback function prints stuff to the screen via ncurses. So the obvious way to fully test this is to simulate a keyboard and a terminal and make sure that the output is the expected. However this sounds too complicated. I was thinking about adding an abstraction layer between the database and the UI so that the callback function will populate a list of entries and that list will later be printed. In that case I would be able to check if that list contains the expected values. However, why would I struggle with a data structure and lists in my program when sqlite3 already does this? For example, if the user wants to see the list sorted in some other way, it would be expensive to throw away the list and repopulate it. I would need to sort the list, but why should I implement sorting when sqlite3 already has that? Using my orginal design I could just do an other query sorted differently. Previously I've only done TDD with command line applications, and there it's really easy to just compare the output with what I'm expected. An other way would be to add CLI interface to the program and wrap a test program around the CLI to test everything. (The way git.git does with it's test-framework). So the question is, how to add testing to a tightly integrated database/UI.

• I can't program because the code I am using uses old coding styles. Is this normal to programmers? [closed]

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: Does not have comments Does not have functions (50, 100, 200, 300 or more lines executed in sequence) Uses a lot of if statements with a lot of paths Has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) Uses an old language (Visual FoxPro 8 from 2002), but there are new releases from 2007. I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way? EDIT: All the answers are very good. For my (un)hope, appears that there are a lot of this kind of code bases around the world. A point mentioned to all answers is refactor the code. Yeah, I really like to do it. In my personal project, I always do this, but... I can't refactor the code. Programmers are only allowed to change the files in the task that they are designed for. Every change in old code must be keep commented in the code (even with Subversion as version control), plus meta informations (date, programmer, task) related to that change (this became a mess, there are code with 3 used lines and 50 old lines commented). I'm thinking that is not only a code problem, but a management of software development problem.

• What is the R Language?

  - by TATWORTH

  I encountered the R Language recently with O'Reilly books and while from the context I knew it was a language for dealing with statistics, doing a web search for the support web site was futile. However I have now located the web site and it is at http://www.r-project.org/R is a free language available for a number of platforms including windows. CRAN mirrors are available at a number of locations worldwide.Here is the official description:"R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS."

• Handling game logic events by behavior components

  - by chehob

  My question continues on topic discussed here I have tried implementing attribute/behavior design and here is a quick example demonstrating the issue. class HealthAttribute : public ActorAttribute { public: HealthAttribute( float val ) : mValue( val ) { } float Get( void ) const { return mValue; } void Set( float val ) { mValue = val; } private: float mValue; }; class HealthBehavior : public ActorBehavior { public: HealthBehavior( shared_ptr< HealthAttribute > health ) : pHealth( health ) { // Set OnDamage() to listen for game logic event "DamageEvent" } void OnDamage( IEventDataPtr pEventData ) { // Check DamageEvent target entity // ( compare my entity ID with event's target entity ID ) // If not my entity, do nothing // Else, modify health attribute with received DamageEvent data } protected: shared_ptr< HealthAttribute > pHealth; }; My question - is it possible to get rid of this annoying check for game logic events? In the current implementation when some entity must receive damage, game logic just fires off event that contains damage value and the entity id which should receive that damage. And all HealthBehaviors are subscribed to the DamageEvent type, which leads to any entity possesing HealthBehavior call OnDamage() even if he is not the addressee.

• Cry Engine 3 vs UDK

  - by Daniele Riccardelli

  I'm new here and I hope that other people may find this question interesting. Me and a bunch of guys from my University are thinking about getting started in game development, but, even though the game design is kind of ready, we are stucked at the point "which Engine should we choose". At first, we were thinking about Unity3D Free, in particular because we are pretty familiar with C# and, even better, it's completely free, but on the other hand there are some cons like no dynamic shadowing that make the realization of our game kinda hard. So, we are thinking about moving either to UDK or Cry Engine, since they are not as expensive as Unity3D Pro (at least before the game deployment) . The thing we are worried the most, though, is that we are kind of scared about the support for team work(i mean, that we might find it hard to coordinate our efforts without software support), since in Unity3D the team features are part of purchasable content, and we are not interested in paying that much for a project we are not even sure we can complete. So, finally, I hope one of you knows the mentioned engines enough to give us a tip telling which one offers better team features and is advisable for guys that have barely worked before on videogames but have good object oriented programming skills. Probably might be helpful for your suggestion, if i say that our game is an exploration game. Thanks to anybody who's going to answer.

• Get to No as fast as possible

  - by Tim Hibbard

  There is a sales technique where the strategy is to get the customer to say “No deal” as soon as possible.  The idea being that by establishing terms that your customer is not comfortable with with, the sooner you can figure out what they will be willing to agree to.  The same principal can be applied to code design.  Instead of nested if…then statements, a code block should quickly eliminate the cases it is not equipped to handle and just focus on what it is meant to handle. This is code that will quickly become maintainable as requirements change: private void SaveClient(Client c) { if (c != null) { if (c.BirthDate != DateTime.MinValue) { foreach (Sale s in c.Sales) { if (s.IsProcessed) { SaveSaleToDatabase(s); } } SaveClientToDatabase(c); } } }   If an additional requirement comes along that requires the Client to have Manager approval or for a Sale to be under $20K, this code will get messy and unreadable. A better way to meet the same requirements would be: private void SaveClient(Client c) { if (c == null) { return; } if (c.BirthDate == DateTime.MinValue) { return; }   foreach (Sale s in c.Save) { if (!s.IsProcessed) { continue; } SaveSaleToDatabase(s); } SaveClientToDatabase(c); } This technique moves on quickly when it finds something it doesn’t like.  This makes it much easier to add a Manager approval constraint.  We would just insert the new requirement before the action takes place.

• Move unity launcher to bottom of the screen

  - by argvar

  I have Ubuntu 13.04 DESKTOP version and for some odd reason I'm told that the Unity launcher cannot be moved to the bottom of the screen because of several reasons: 1. Canonical wants it there so it fits with their overall design goals, namely when it comes to touchscreen devices and netbooks. This in my mind totally ignores the fact that most Ubuntu users are DESKTOP users. No matter what Canonicals long term goal is, it surely mustn't be at the expense of needs of their core user base. 2. Most monitors are widescreen, the launcher is more compact where it is. This is not only taking away the users choice, but is also a wrong assessment. Widescreen monitors can sometimes be rotated on a pivot, giving it a portrait aspect. By displaying the Unity launcher on the left side it takes up a lot of space. Many desktop users have multiple monitors, and having the launcher on the left side of each monitor is very awkward. Also, many websites are catered to fit on a half 1920 display, so you can have two browser windows open side-by-side with all content visible. The placement of the Unity launcher takes away the horizontal space meaning there's less room for each browser window, and you'll see the right side of the web pages being occluded. Any suggestion to simply hide the Unity launcher, or "Canonical knows best" or "get used to it" are unwelcome and totally ignores the above points. Linux is about choice. Canonical's stubbornness with the Unity launcher placement is inconsistent with what Linux is about.

• PHP Image gallery that integrates well into custom CMS

  - by Thorarin

  I've been trying to find an image gallery that plays nice with our custom CMS. I've evaluated a number of them, but none of them seems to have the feature list that I would like: Run on LAMP environment Free software or low license costs (the website belongs to a non-profit organisation) Multi-user support Multiple albums. We're posting concert pictures, and would like an album per event. Pluggable authentication system. I want to reuse the accounts we have for our CMS. Permissions can be done inside the gallery itself, but I want to have a single sign on solution in a maintainable manner, by writing my own plugin/add-on for the software. Upload support (multiple images at the same time) And preferrably also: Can be integrated into a PHP page layout without IFRAMEs Automatic resizing of uploaded images to a maximum size Ability for visitors to place comments This combination is proving hard to find, especially the authentication requirement. I don't want to mess around all over the place in the source code to make it use the existing authentication. A plugin would be ideal, but alternatively a well thought out software design that allows for maintainable surgical changes would be acceptable. Any suggestions on which software I should take a closer look into?

• POLL: How do you build your interfaces in xcode for iphone/coco-touch applications?

  - by LolaRun

  Hi all, It's been 2 months i'm using xcode and building iphone apps, and i'm finding it really hard to grasp the good design for the applications. I always face problems like you can't put your tabbarcontroller in another custom viewcontroller sort of a thing? or other problems... That 'sometimes' - of course - would work if you did the creation of the views/viewcontrollers programmatically. so I don't know if i should start writing the creation of my objects or use interface builder. This is why i'm asking this poll question, to see what's the most accepted way among other developers. I'm not going to answer my question, so the votes would not increase my reputation and risk my poll being closed soon. I prefer that the first two readers of this question should answer by 'using IB' and the second one 'programmatically' and the rest would vote up or down for these two answers. And don't vote my question either, i just need to know, and maybe someone else wants to know. so the longer this question lives the better. and gaining nothing from it concerning reputation would help that cause. thank you all for your cooperation. and go ahead and answer Peace

• What constitutes a programming language and how does one copyright a programming language?

  - by Yannbane

  I've decided to create a programming language of my own, mostly just for fun. However, I got interested in the legal aspect of it all. You can, for example, licence specific programs under specific terms. However, how do you go about licensing a language? Also, by that I don't just mean the implementation of the language (compiler & VM), but the standard itself. Is there something else to a programming language I'm missing? What I would like to achieve by such licensing: Make it completely FOSS (can a language even be FOSS, or is that the implementation that can be FOSS?) Establish myself as the author (can you legally be an author of a language? Or, again, just the implementation?) Make it so that anyone implementing my language would be required to attribute me (MIT-style. Please note that I do not have any hopes for anyone actually ever doing that though, I'm just learning.) I think that the solution would be to separately license the VM and the compiler for my language, as "the official implementation", and then license the design document as the language itself. What exactly am I missing here?

• Javascript is not loading

  - by Oden

  Hey, I've got a problem with JavaScript under Ubuntu, that drives me crazy. I'm using Gedit for my web sites since I'm an Ubuntu user. When I start a new website I create (usually with the gnome terminal) folder structure, and I copy the files I need into them. The next step is creating an index.html where I build the design and basic JavaScript functionality. JavaScript is stored in a sub-folder of the project and when i try to load one using the tag in the header, my whole page body disappears. If the source contains a script tag with its own body, and its not the first its code wont run. I've tried to solve the problem by setting chmod to 777 with sudo chmod -R 777 . but nothing changed. CSS is loading correctly, but JS isn't. I'm using the newest version of apache, no mod_rewrite stuff, but i get the same problem when I run the html from file (file:///...) Do anyone know how to solve this problem?

• Welcome to the Gamification Blog!

  - by erikanollwebb

  If you are here, you have probably been hearing about gamification and game mechanics, and wondering how it all fits into the enterprise space.  Although I've been leading some efforts in the Fusion Apps UX team on gamification for a while, I have left it to a couple of others to blog on it.  For example, check out the links below from Ultan Ó Broin if you haven't seen these already: #gamifyOracle: Oracle Applications Gamification Worldwide #UX Design Jam Oracle Applications UX Gamification Worldwide All Hands Day Gamification, Schamification: Reality Isn't Broken. Your User Experience Is I've been tweeting to #GamifyOracle for a while but I'll try to use this blog to put a little of my own thoughts on the matter together.  In the meantime, I spoke at the GSummit in June on the things we're working on and I'll be leading a workshop and speaking on Enterprise Gamification at the Enterprise Gamification Summit in September.  Oracle peeps, let me know if you are interested in attending, since we can get a group discount for the workshop/summit.  We're also planning to conduct some more research on gamification in the enterprise space at Oracle OpenWorld this October.  In the meantime, let me know if there are issues you are interested in and I'll try to put some things together here.  I'd love to know who all is working on gamification in Oracle--I know some of you but I'm sure there are others!

• One site being on a subdirectory of another. Does google count this againt you?

  - by Mick

  I have created two similar websites (relating to monetary systems). So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for the successful one, but less liked one is just an "add-on" which sits on a subdirectory of the successful one. I wonder if Google somehow detects this and treats it as a less significant website? EDIT: Just to clarify, even though one site is an add-on that sits on a subdirectory of the other, the URL is arranged to look like it is a root. I.e. the unpopular site can be accessed directly with a simple www.myunpopularsite.com name, without specifying any subdirectory.

• Opinion: Passwords as a concept are completely broken

  - by Greg Low

  One thing you get to do as you get older, or have been around the industry for a long time, is to pontificate. My pet topic today is passwords. I think that they are, as a concept, now completely broken and have been for a long time. We tell users:1. Pick something really complex2. Don't write it down3. Change it regularly4. Use a different password for each site, and often each role that you hold in each site5. Deal with the fact that we apply different rules for passwords on each siteetc, etc.Is this even humanly possible? I don't think it is. Yet we blame the users when "they" get it wrong. How can they be getting it wrong when we design a system that requires super-human ability to comply. (These guys are potential exceptions: http://www.worldmemorychampionships.com/) We are the ones that are getting it wrong and it's long overdue that we, as an industry, need to apply our minds to fixing it, instead of assuming that users should just deal with it.

• Offshoring: does it ever work?

  - by DanSingerman

  I know there has been a fair amount of discussion on here about outsourcing/offshoring, and the general opinion seems to be that at best it is difficult, and at worst it fails. I have direct experience of offshoring myself; a previous company where I was a dev manager wanted to send some development offshore, and we ran a pilot scheme to see how well it would work. Of course it was a complete failure, although it is not completely clear to me whether this was down to the offshore devs being less talented, the process, or other factors (no doubt it was really a combination). I can see as a business how offshoring looks attractive (much lower day rate), but as far as I can see, the only way it could possibly work is if you do exceptionally detailed design up front, with incredibly detailed specifications; and by the time you have invested in producing that, you have probably spent as nearly as much as if you had written the actual code locally (which I think is an instance of No Silver Bullet) So, what I want to know is, does anyone here have any experience of offshoring actually working ever? Especially if there are any success stories of it working in a semi-agile way? I know there are developers here from all over the World; has anyone worked on an offshore project they consider successful?

• Engineered Systems and PCI

  - by Joel Weise

  Oracle has a number of different engineered systems.  These are design to be highly integrated, optimized and secure systems.  The Exadata database engineered system and the Exalogic application engineered system are two good examples.  Often I am asked how these comply with different standards and regulations.  Exalogic is the Oracle engineered system that supports applications and the focus of today's blog.  First, we must recognize that as a collection of hardware and software, we cannot simply state that Exalogic is "compliant" with PCI DSS.  This is because Exalogic must be implemented within the context of one's existing IT infrastructure, the security features of that infrastructure, the governance framework that exists, security policies, operational procedures, and other factors.  What we can say though, is that Exalogic has been designed with various security capabilities that can be utilized to support compliance to PCI DSS as well as other standards and regulations (e.g., NIST and HIPAA).  Given that, Exalogic can be an excellant platform for running PCI related payment applications.  Coalfire Systems, a leading QSA in the US, has evaluated Exalogic against PCI DSS and supports this position.  Their evaluation can be found here: Exalogic and PCI Compliance. I hope you find it useful.
