  - by Haseeb Akhtar

  We have migrated from SharePoint 2010 foundation to SharePoint 2010 standard. Now, the problem is we are looking for Secure Store Service on 'Services on Server' page in Central Administration, but we didn't see it. We have another server where SharePoint 2010 standard is installed and there we can see Secure Store Service available. Please let me know what needs to be done for the same. Thanks in Advance

• Working for free?

  - by Jonny

  I came across this article Work for Free that got me thinking. The goal of every employer is to gain more value from workers than the firm pays out in wages; otherwise, there is no growth, no advance, and no advantage for the employer. Conversely, the goal of every employee should be to contribute more to the firm than he or she receives in wages, and thereby provide a solid rationale for receiving raises and advancement in the firm. I don't need to tell you that the refusenik didn't last long in this job. In contrast, here is a story from last week. My phone rang. It was the employment division of a major university. The man on the phone was inquiring about the performance of a person who did some site work on Mises.org last year. I was able to tell him about a remarkable young man who swung into action during a crisis, and how he worked three 19-hour days, three days in a row, how he learned new software with diligence, how he kept his cool, how he navigated his way with grace and expertise amidst some 80 different third-party plug-ins and databases, how he saw his way around the inevitable problems, how he assumed responsibility for the results, and much more. What I didn't tell the interviewer was that this person did all this without asking for any payment. Did that fact influence my report on his performance? I'm not entirely sure, but the interviewer probably sensed in my voice my sense of awe toward what this person had done for the Mises Institute. The interviewer told me that he had written down 15 different questions to ask me but that I had answered them all already in the course of my monologue, and that he was thrilled to hear all these specifics. The person was offered the job. He had done a very wise thing; he had earned a devotee for life. The harder the economic times, the more employers need to know what they are getting when they hire someone. The job applications pour in by the buckets, all padded with degrees and made to look as impressive as possible. It's all just paper. What matters today is what a person can do for a firm. The resume becomes pro forma but not decisive under these conditions. But for a former boss or manager to rave about you to a potential employer? That's worth everything. What do you think? Has anyone here worked for free? If so, has it benefited you in any way? Why should(nt) you work for free (presuming you have the money from other means to keep you going)? Can you share your experience? Me, I am taking a year out of college and haven't gotten a degree yet so that's probably why most of my job applications are getting ignored. So im thinking about working for free for the experience?

• How can one manage thousands of IF...THEN...ELSE rules?

  - by David

  I am considering building an application, which, at its core, would consist of thousands of if...then...else statements. The purpose of the application is to be able to predict how cows move around in any landscape. They are affected by things like the sun, wind, food source, sudden events etc. How can such an application be managed? I imagine that after a few hundred IF-statements, it would be as good as unpredictable how the program would react and debugging what lead to a certain reaction would mean that one would have to traverse the whole IF-statement tree every time. I have read a bit about rules engines, but I do not see how they would get around this complexity.

• Is it worth to learn programming for windows?

  - by Herr Kaleun

  as a programmer, i was skeptical about (Microsoft) desktop software back in the early 2000s (i was a kid then) and yet, i was right. So i advanced to PHP in 2004 and began working on Web applications. When i look at the software world today, i really can't understand, how software for Microsoft or call it, "windows" should have a future. Is it still worth, learning it? I have a strong feeling that, in about 3-4 years, mac will have the dominance in the Personal Computer market. If i am wrong, please correct me. Thanks!

• Acceptance tests done first...how can this be accomplished?

  - by Crazy Eddie

  The basic gist of most Agile methods is that a feature is not "done" until it's been developed, tested, and in many cases released. This is supposed to happen in quick turnaround chunks of time such as "Sprints" in the Scrum process. A common part of Agile is also TDD, which states that tests are done first. My team works on a GUI program that does a lot of specific drawing and such. In order to provide tests, the testing team needs to be able to work with something that at least attempts to perform the things they are trying to test. We've found no way around this problem. I can very much see where they are coming from because if I was trying to write software that targeted some basically mysterious interface I'd have a very hard time. Although we have behavior fairly well specified, the exact process of interacting with various UI elements when it comes to automation seems to be too unique to a feature to allow testers to write automated scripts to drive something that does not exist. Even if we could, a lot of things end up turning up later as having been missing from the specification. One thing we considered doing was having the testers write test "scripts" that are more like a set of steps that must be performed, as described from a use-case perspective, so that they can be "automated" by a human being. This can then be performed by the developer(s) writing the feature and/or verified by someone else. When the testers later get an opportunity they automate the "script" for regression purposes mainly. This didn't end up catching on in the team though. The testing part of the team is actually falling behind us by quite a margin. This is one reason why the apparently extra time of developing a "script" for a human being to perform just did not happen....they're under a crunch to keep up with us developers. If we waited for them, we'd get nothing done. It's not their fault really, they're a bottle neck but they're doing what they should be and working as fast as possible. The process itself seems to be set up against them. Very often we end up having to go back a month or more in what we've done to fix bugs that the testers have finally gotten to checking. It's an ugly truth that I'd like to do something about. So what do other teams do to solve this fail cascade? How can we get testers ahead of us and how can we make it so that there's actually time for them to write tests for the features we do in a sprint without making us sit and twiddle our thumbs in the meantime? As it's currently going, in order to get a feature "done", using agile definitions, would be to have developers work for 1 week, then testers work the second week, and developers hopefully being able to fix all the bugs they come up with in the last couple days. That's just not going to happen, even if I agreed it was a reasonable solution. I need better ideas...

• How do you develop web applications? [closed]

  - by ck3g

  How do you and/or your team develop your web applications? Language, framework or platform doesn't matter. I would like to know about the structure of your environment. For example: Using IDE on workstation and project files on remote host accessing via sftp. Files are saved instantly on remote host; All files are local and are uploaded on remote host during saving; Files are local, web server is running on local computer and is tested at local host. etc. You could write down also about the benefits of your approach, this will be useful for me. Thanks upd: Here must be a question and here it is: which is the best approach by your opinion?

• I'm tasked with leading the documentation effort for an existing, entirely undocumented, software product - what resources are there to help me?

  - by Ben Rose

  I'm a software developer at a technology company. I have been tasked with leading the documentation effort for the product I work on. The goal is to produce documentation internal to developer, and the project spills over into the business side, where it covers requirements documentation. This project is challenging. Specifically, I'm dealing with a product which: - has been around for a long time, at least 6 years. - has no form of documentation other than some small, outdated pieces here and there. - has comments in the code, but they are technical and do not convey any over-arching behavior (even on technical side). - as a consequence of having little to no documentation, is often unnecessarily complex under the covers In addition, we have not been given a lot of time to work on this project. I do not have any formal documentation or writing background, training, or experience. I have displayed some ability in writing/communication around the office, which may be why I was assigned to this project. Please share your advice or recommendation for resources to help me prepare and deal with this project. I'm looking for references to books/website/forums/whatever, to help me come up with the design of a plan with milestones, learn about best practices, task delegation, templates, buy-in, etc. I'm hoping specifically for resources targeting or giving special mention of introducing good documentation to existing, undocumented, projects. I would be very grateful for your responses. Ben

• Integration of advertisement into WP7 apps: Any experiences?

  - by OneWorld

  Has anyone of you guys integrated or is thinking about integrating either admob, MS pubCenter, adwhirl or any other advertising provider into your apps? Please share your experience... Who pays best? Any regulations? Any problems with getting the app approved by Microsoft Market? If you chose Admob: Which plugin do you suggest? This or that or another one? Any experiences in Europe or Germany? (MS pubCenter is US only so far) Edit: I think we discussed enough about acceptance of mobile advertisement. Let's focus now on the questions I asked. Edit 2: Hmm, maybe Stackoverlfow is a better place to discuss question 2-5. Could somebody migrate this one?

• How to start competitive programming?

  - by Vaibhav Agarwal

  I am practicing coding for a while but the problem is that it takes me a lot of time to write a solution for the problems. I want to ask if competitive programming can help me in improving this? If yes, then how should I start and from what site like TopCoder? I would obviously won't be able to solve very hard problems for now. What should I do? If no, what else should I do? I also have another problem that I want to learn coding but the thing is that I feel that I am not very good at it. What should I do? It's like bugging me from inside. I know some people may not find this question informative but please at least allow me to get an answer.

• DI and hypothetical readonly setters in C#

  - by Luis Ferrao

  Sometimes I would like to declare a property like this: public string Name { get; readonly set; } I am wondering if anyone sees a reason why such a syntax shouldn't exist. I believe that because it is a subset of "get; private set;", it could only make code more robust. My feeling is that such setters would be extremely DI friendly, but of course I'm more interested in hearing your opinions than my own, so what do you think? I am aware of 'public readonly' fields, but those are not interface friendly so I don't even consider them. That said, I don't mind if you bring them up into the discussion Edit I realize reading the comments that perhaps my idea is a little confusing. The ultimate purpose of this new syntax would be to have an automatic property syntax that specifies that the backing private field should be readonly. Basically declaring a property using my hypothetical syntax public string Name { get; readonly set; } would be interpreted by C# as: private readonly string name; public string Name { get { return this.name; } } And the reason I say this would be DI friendly is because when we rely heavily on constructor injection, I believe it is good practice to declare our constructor injected fields as readonly.

• How can I implement an EPUB reader in JavaScript?

  - by Vlad Nicula

  I'm wondering if I can create an EPUB (free and open e-book standard) reader in JavaScript. The basic requirements would be: Server parts of the EPUB reader from a server API. Read the EPUB data in JavaScript. Render it on page. Provide some extra functionality, like text highlights or page notes. I have no information about how I could do this. I'm willing to try a prototype project. What are the steps that I could take towards implementing such a thing?

• Organizing Git repositories with common nested sub-modules

  - by André Caron

  I'm a big fan of Git sub-modules. I like to be able to track a dependency along with its version, so that you can roll-back to a previous version of your project and have the corresponding version of the dependency to build safely and cleanly. Moreover, it's easier to release our libraries as open source projects as the history for libraries is separate from that of the applications that depend on them (and which are not going to be open sourced). I'm setting up workflow for multiple projects at work, and I was wondering how it would be if we took this approach a bit of an extreme instead of having a single monolithic project. I quickly realized there is a potential can of worms in really using sub-modules. Supposing a pair of applications: studio and player, and dependent libraries core, graph and network, where dependencies are as follows: core is standalone graph depends on core (sub-module at ./libs/core) network depdends on core (sub-module at ./libs/core) studio depends on graph and network (sub-modules at ./libs/graph and ./libs/network) player depends on graph and network (sub-modules at ./libs/graph and ./libs/network) Suppose that we're using CMake and that each of these projects has unit tests and all the works. Each project (including studio and player) must be able to be compiled standalone to perform code metrics, unit testing, etc. The thing is, a recursive git submodule fetch, then you get the following directory structure: studio/ studio/libs/ (sub-module depth: 1) studio/libs/graph/ studio/libs/graph/libs/ (sub-module depth: 2) studio/libs/graph/libs/core/ studio/libs/network/ studio/libs/network/libs/ (sub-module depth: 2) studio/libs/network/libs/core/ Notice that core is cloned twice in the studio project. Aside from this wasting disk space, I have a build system problem because I'm building core twice and I potentially get two different versions of core. Question How do I organize sub-modules so that I get the versioned dependency and standalone build without getting multiple copies of common nested sub-modules? Possible solution If the the library dependency is somewhat of a suggestion (i.e. in a "known to work with version X" or "only version X is officially supported" fashion) and potential dependent applications or libraries are responsible for building with whatever version they like, then I could imagine the following scenario: Have the build system for graph and network tell them where to find core (e.g. via a compiler include path). Define two build targets, "standalone" and "dependency", where "standalone" is based on "dependency" and adds the include path to point to the local core sub-module. Introduce an extra dependency: studio on core. Then, studio builds core, sets the include path to its own copy of the core sub-module, then builds graph and network in "dependency" mode. The resulting folder structure looks like: studio/ studio/libs/ (sub-module depth: 1) studio/libs/core/ studio/libs/graph/ studio/libs/graph/libs/ (empty folder, sub-modules not fetched) studio/libs/network/ studio/libs/network/libs/ (empty folder, sub-modules not fetched) However, this requires some build system magic (I'm pretty confident this can be done with CMake) and a bit of manual work on the part of version updates (updating graph might also require updating core and network to get a compatible version of core in all projects). Any thoughts on this?

• Brief explanation for executables in a GNU/Clang Toolchain?

  - by ZhangChn

  I roughly understand that cc, ld and other parts are called in a certain sequence according to schemes like Makefiles etc. Some of those commands are used to generate those configs and Makefiles. And some other tools are used to deal with libraries. But what are other parts used for? How are they called in this process? Which tool would use various parser generators? Which part is optional? Why? Is there a brief summary get these explained on how the tools in a GNU or LLVM/Clang toolchain are organised and called in a C/C++ project building? Thanks in advance.

• Pythonic use of the isinstance function?

  - by Pace

  Whenever I find myself wanting to use the isinstance() function I usually know that I'm doing something wrong and end up changing my ways. However, in this case I think I have a valid use for it. I will use shapes to illustrate my point although I am not actually working with shapes. I am parsing XML configuration files that look like the following: <square> <width>7</width> </square> <rectangle> <width>5</width> <height>7</height> </rectangle> <circle> <radius>4</radius> </circle> For each element I create an instance of the Shape class and build up a list of Shape objects in a class called the ShapeContainer. Different parts of the rest of my application need to refer to the ShapeContainer to get certain shapes. Depending on what the code is doing it might need just rectangles, or it might operate on all quadrangles, or it might operate on all shapes. I have created the following function in the ShapeContainer class (the actual function uses a list comprehension but I have expanded it here for readability): def locate(self, shapeClass): result = [] for shape in self.__shapes: if isinstance(shape,shapeClass): result.append(shape) return result Is this a valid use of the isinstance function? Is there another way I can do this which might be more pythonic?

• What are some of the benefits of a "Micro-ORM"?

  - by Wayne M

  I've been looking into the so-called "Micro ORMs" like Dapper and (to a lesser extent as it relies on .NET 4.0) Massive as these might be easier to implement at work than a full-blown ORM since our current system is highly reliant on stored procedures and would require significant refactoring to work with an ORM like NHibernate or EF. What is the benefit of using one of these over a full-featured ORM? It seems like just a thin layer around a database connection that still forces you to write raw SQL - perhaps I'm wrong but I was always told the reason for ORMs in the first place is so you didn't have to write SQL, it could be automatically generated; especially for multi-table joins and mapping relationships between tables which are a pain to do in pure SQL but trivial with an ORM. For instance, looking at an example of Dapper: var connection = new SqlConnection(); // setup here... var person = connection.Query<Person>("select * from people where PersonId = @personId", new { PersonId = 42 }); How is that any different than using a handrolled ADO.NET data layer, except that you don't have to write the command, set the parameters and I suppose map the entity back using a Builder. It looks like you could even use a stored procedure call as the SQL string. Are there other tangible benefits that I'm missing here where a Micro ORM makes sense to use? I'm not really seeing how it's saving anything over the "old" way of using ADO.NET except maybe a few lines of code - you still have to write to figure out what SQL you need to execute (which can get hairy) and you still have to map relationships between tables (the part that IMHO ORMs help the most with).

• Odd company release cycle: Go Distributed Source Control?

  - by MrLane

  sorry about this long post, but I think it is worth it! I have just started with a small .NET shop that operates quite a bit differently to other places that I have worked. Unlike any of my previous positions, the software written here is targetted at multiple customers and not every customer gets the latest release of the software at the same time. As such, there is no "current production version." When a customer does get an update, they also get all of the features added to he software since their last update, which could be a long time ago. The software is highly configurable and features can be turned on and off: so called "feature toggles." Release cycles are very tight here, in fact they are not on a shedule: when a feature is complete the software is deployed to the relevant customer. The team only last year moved from Visual Source Safe to Team Foundation Server. The problem is they still use TFS as if it were VSS and enforce Checkout locks on a single code branch. Whenever a bug fix gets put out into the field (even for a single customer) they simply build whatever is in TFS, test the bug was fixed and deploy to the customer! (Myself coming from a pharma and medical devices software background this is unbeliveable!). The result is that half baked dev code gets put into production without being even tested. Bugs are always slipping into release builds, but often a customer who just got a build will not see these bugs if they don't use the feature the bug is in. The director knows this is a problem as the company is starting to grow all of a sudden with some big clients coming on board and more smaller ones. I have been asked to look at source control options in order to eliminate deploying of buggy or unfinished code but to not sacrifice the somewhat asyncronous nature of the teams releases. I have used VSS, TFS, SVN and Bazaar in my career, but TFS is where most of my experience has been. Previously most teams I have worked with use a two or three branch solution of Dev-Test-Prod, where for a month developers work directly in Dev and then changes are merged to Test then Prod, or promoted "when its done" rather than on a fixed cycle. Automated builds were used, using either Cruise Control or Team Build. In my previous job Bazaar was used sitting on top of SVN: devs worked in their own small feature branches then pushed their changes to SVN (which was tied into TeamCity). This was nice in that it was easy to isolate changes and share them with other peoples branches. With both of these models there was a central dev and prod (and sometimes test) branch through which code was pushed (and labels were used to mark builds in prod from which releases were made...and these were made into branches for bug fixes to releases and merged back to dev). This doesn't really suit the way of working here, however: there is no order to when various features will be released, they get pushed when they are complete. With this requirement the "continuous integration" approach as I see it breaks down. To get a new feature out with continuous integration it has to be pushed via dev-test-prod and that will capture any unfinished work in dev. I am thinking that to overcome this we should go down a heavily feature branched model with NO dev-test-prod branches, rather the source should exist as a series of feature branches which when development work is complete are locked, tested, fixed, locked, tested and then released. Other feature branches can grab changes from other branches when they need/want, so eventually all changes get absorbed into everyone elses. This fits very much down a pure Bazaar model from what I experienced at my last job. As flexible as this sounds it just seems odd to not have a dev trunk or prod branch somewhere, and I am worried about branches forking never to re-integrate, or small late changes made that never get pulled across to other branches and developers complaining about merge disasters... What are peoples thoughts on this? A second final question: I am somewhat confused about the exact definition of distributed source control: some people seem to suggest it is about just not having a central repository like TFS or SVN, some say it is about being disconnected (SVN is 90% disconnected and TFS has a perfectly functional offline mode) and others say it is about Feature Branching and ease of merging between branches with no parent-child relationship (TFS also has baseless merging!). Perhaps this is a second question!

• Can One Get a Solid Programming Foundation Without Going To College/University?

  - by Daniel

  First, I have already searched the site and read all the previous "self-taught vs. college" topics. The majority of the answers defended that going to college was the best choice, for two main reasons: Going to college gives you the paper, which is essential to landing jobs, especially in tough economic times. Going to college gives you a solid programming base, teaching you the principles that will be essential regardless of the language/path you take after. Here comes my question: I am not worried about reason 1 at all, because I already have my own company (I build websites/ do affiliate marketing) and a stable financial situation, so I am pretty sure I won't need to look around for a job. I am worried about reason 2 though. That is, I want to make sure I'll have as solid a programming foundation as anyone else out there, and I am wondering if that is possible with self-learning. Suppose I take my time to study the very basics, like discrete maths, algorithm design, programming logic, computer architecture, Assembly, C programming, databases and data structures - mostly using books,online resources and lots of coding. Say I spend 1-2 years covering those basics. Do you think my foundation would be solid, or still lack in comparison to someone who went to college?

• Continual Professional Development - proving new skills to non-technical employers

  - by Tom

  Background I work in a non-IT based company, as a professional software developer, building a large scale internal database system. I am fortunate to have a fairly senior position within the company, and have been working here for around 4 years. Often I get asked by management "how do you learn new things?". To be honest, I don't know how to answer this. Over the last 6 months, I've really gotten my teeth into some new techniques and technologies to make my level of coding far better and hopefully improve the quality of the software. Even if it's just refreshing my skills on things I've learnt already. Like last week I dived into some complex XLinq and TPL code (.net). Nothing revolutionary, but I feel like I am a bit better than before. Question The question is, how do I prove this to my employer? It'd be nice to be able to put this on paper. Possibilities I could: Keep a journal of what I've learnt - keeping the technical bits in (nobody would understand or care, but it's better than them being omitted) ???? (I've run out of ideas already) Any ideas? Thanks, Tom

• Should my dropdown of recently used items show items I no longer have access to

  - by Dan Hibbert

  We are implementing a client for our document management system. Part of this is the checkin screen where one of the fields a user chooses is the folder where the document should be checked into. In our original system, this was represented with a combobox where a user could hand type a folder path or select a path from a list of 5 folders they'd recently used for checking. It is possible that between the time they used the folder and the time they are doing the new checkin the user will no longer have access to the folder. At present, we still show the folder as an option and then, if the user chooses that folder, display an error message when the user submits the check in. We are thinking of removing these recently used folders the user doesn't have access to (we'll make a check when the form is instantiated) because why show an option if we know it will cause a failure (and another dialog message the user has to OK). However, an opposite opinion is that if we remove those folders, the users will think the system has "forgotten" their recent choices and will lose trust in what they are using. I'd like to get some opinions on the better user experience for this problem.

• Algorithm for Shortest Job First with Preemption

  - by Shray

  I want to implement a shortest job first routine using C# or C++. Priority of Jobs are based on their processing time. Jobs are processed using a binary (min) heap. There are three types of jobs. Type 1 is when jobs come in between every 4-6 seconds, with processing times between 4-6. Type 2 job comes in between 8-12 seconds, with processing times between 8-12. Type 3 job comes in between 24-26 seconds, with processing times between 14-16. So far, I have written the binary heap functionality, but Im kinda confused on how to start processing spawn and also the processor. #include <iostream> #include <stdlib.h> #include <time.h> using namespace std; int timecounting = 20; struct process{ int atime; int ptime; int type; }; class pque{ private: int count; public: process pheap[100]; process type1[100]; process type2[100]; process type3[100]; process type4[100]; pque(){ count = 0; } void swap(int a, int b){ process tempa = pheap[a]; process tempb = pheap[b]; pheap[b] = tempa; pheap[a] = tempb; } void add(process c){ int current; count++; pheap[count] = c; if(count > 0){ current = count; while(pheap[count/2].ptime > pheap[current].ptime){ swap(current/2, current); current = current/2; } } } void remove(){ process temp = pheap[1]; // saves process to temporary pheap[1] = pheap[count]; //takes last process in heap, and puts it at the root int n = 1; int leftchild = 2*n; int rightchild = 2*n + 1; while(leftchild < count && rightchild < count) { if(pheap[leftchild].ptime > pheap[rightchild].ptime) { if(pheap[leftchild].ptime > pheap[n].ptime) { swap(leftchild, n); n = leftchild; int leftchild = 2*n; int rightchild = 2*n + 1; } } else { if(pheap[rightchild].ptime > pheap[n].ptime) { swap(rightchild, n); n = rightchild; int leftchild = 2*n; int rightchild = 2*n + 1; } } } } void spawn1(){ process p; process p1; p1.atime = 0; int i = 0; srand(time(NULL)); while(i < timecounting) { p.atime = rand()%3 + 4 + p1.atime; p.ptime = rand()%5 + 1; p1.atime = p.atime; p.type = 1; type1[i+1] = p; i++; } } void spawn2(){ process p; process p1; p1.atime = 0; srand(time(NULL)); int i = 0; while(i < timecounting) { p.atime = rand()%3 + 9 + p1.atime; p.ptime = rand()%5 + 6; p1.atime = p.atime; p.type = 2; type2[i+1] = p; i++; } } void spawn3(){ process p; process p1; p1.atime = 0; srand(time(NULL)); int i = 0; while(i < timecounting) { p.atime = rand()%3 + 25 + p1.atime; p.ptime = rand()%5 + 11; p1.atime = p.atime; p.type = 3; type3[i+1] = p; i++; } } void spawn4(){ process p; process p1; p1.atime = 0; srand(time(NULL)); int i = 0; while(i < timecounting) { p.atime = rand()%6 + 30 + p1.atime; p.ptime = rand()%5 + 8; p1.atime = p.atime; p.type = 4; type4[i+1] = p; i++; } } void processor() { process p; process p1; p1.atime = 0; int n = 1; int n1 = 1; int n2 = 1; for(int i = 0; i<timecounting;i++) { if(type1[n].atime == i) { add(type1[n]); n++; } if(type2[n1].atime == i) { add(type1[n1]); n1++; } if(type3[n2].atime == i) { add(type1[n2]); n2++; } /* if(pheap[1].atime <= i) { while(pheap[1].atime != 0){ pheap[1].atime--; i++; } remove(); }*/ } } };

• Is there a language or design pattern that allows the *removal* of object behavior or properties in a class hierarchy?

  - by Sebastien Diot

  A well-know shortcoming of traditional class hierarchies is that they are bad when it comes to model the real world. As an example, trying to represent animals species with classes. There are actually several problems when doing that, but one that I never saw a solution to is when a sub-class "looses" a behavior or properties that was defined in a super-class, like a penguin not being able to fly (there are probably better examples, but that's the first one that comes to my mind, having seen "Madagascar 2" recently). On the one hand, you don't want to define for every property and behavior some flag that specifies if it is at all present, and check it every time before accessing that behavior or property. You would just like to say that birds can fly, simply and clearly, in the Bird class. But then it would be nice if one could define "exceptions" afterward, without having to use some horrible hacks everywhere. This often happens when a system has been productive for a while. You suddenly find an "exception" that doesn't fit in the original design at all, and you don't want to change a large portion of your code to accommodate it. So, is there some language or design patterns that can cleanly handle this problem, without requiring major changes to the "super-class", and all the code that uses it? Even if a solution only handle a specific case, several solutions might together form a complete strategy. [EDIT] Forgot about the Liskov Substitution Principle. That is why you can't do it. Assuming you define "traits/interfaces" for all major "feature groups", you can freely implement traits in different branches of the hierarchy, like the Flying trait could be implemented by Birds, and some special kind of squirrels and fish. So my question could amount to "How could I un-implement a trait?" If your super-class is a Java Serializable, you have to be one too, even if there is no way for you to serialize your state, for example if you contained a "Socket". So one way to do it is to always define all your traits in pair from the start: Flying and NotFlying (which would throw UnsupportedOperationExceiption, if not checked against). The Not-trait would not define any new interface, and could be simply checked for. Sounds like a "cheap" solution, in particular if used from the start.

• Conways Game of Life C#

  - by Darren Young

  Hi, Not sure if this is the correct place for this question or SO - mods please move if necessary. I am going to have a go at creating GoL over the weekend as a little test project : http://en.wikipedia.org/wiki/Conway's_Game_of_Life I understand the algorithm, however I just wanted to check regarding the implementation, from maybe somebody that has tried it. Essentially, my first (basic) implementation, will be a static grid at a set speed. If I understand correctly, these are the steps I will need: Initial seed Create 2d array with initial set up Foreach iteration, create temporary array, calculating each cells new state based on the Game of Life algorithm Assign temp array to proper array. Redraw grid from proper array. My concerns are over speed. When I am populating the grid from the array, would it simply be a case of looping through the array, assigning on or off to each grid cell and then redraw the grid? Am I on the correct path?

• Rights and use of developed software

  - by Nils Munch

  I have been working on a piece of software for a company, that they wish to resell. There was an mail-based agreement upon a flat hourly rate for my work, and eager me chose to accept a rather low fee. Due to the stress and tempo of the task, a direct contract was never formed or signed. The software was developed locally on my machine, and I was pretty much alone with it, except by excellent help from StackOverflow when I got stuck. Now, the software is nearing completion, I suddenly hear that they have hired a new developer to make the same piece of software as me, and that I was expected to resign within long. Confused I ask around, and realize that the CEO of the company had informed the rest of the company that I was terminally ill and had cancer, and was expected to leave the company soon. Since I'm perfectly healthy, this confused me even more, until I realized what was going on. When I confronted my boss with this, I was no longer seen as a member of the company, and I left the same day, never to return. Later, I raised the question about my missing pay, since I had been working for quite a bit, and not received any payment for my software. I saw that they had already sold a fair copy of my software, and since it's not exactly sold cheap, the company should have plenty of gold to pay me. The company refused, and said that they owned the software, and everything it contained. That was a lot of drama, but my question is this: Who has the rights to the software ? The source code had my personal watermarks and copyrights inprinted, but they have since simply deleted it. The company claim that they have all the rights, because they have a website made about the product, where they write that they have "All rights reserved" in the bottom. My instinct tells me that if a company buys a service like this, and then refuses to pay their developer, then they should not be allowed to keep, and much less resell the product. I have not signed any agreements about giving the company the use of this product, I have made it in my own time and without help from the rest of the company. This all takes place in Denmark, Europe, but I would guess that the rules about this is somewhat universal. Im not the strongest person to legal-talk, so I might be wrong.
