  • Should companies require developers to credit code they didn't write?

    - by sunpech
    In academia, it's considered cheating if a student copies code/work from someone/somewhere else without giving credit, and tries to pass it off as his/her own. Should companies make it a requirement for developers to properly credit all non-trivial code and work that they did not produce themselves? Is it useful to do so, or is it simply overkill? I understand there are various free licenses out there, but if I find stuff I like and actually use, I really feel compelled to give credit via comment in code even if it's not required by the license (or lack thereof one).

  • Can I use access used by Visual Basic for building a database [on hold]

    - by user3413537
    I am the only programmer where I work (summer job) and I am a student with only a few years of programming experience. So I was asked to build a database and I am very excited about this project because hopefully I can learn a lot from this. Using this database my manager is supposed to be able to assign work (dealing with businesses) to different people within the company using an interface (all workers have a shared drive). When workers are done with that paperwork related to the business, they can check off that its done, add comments at the bottom of the interface, and then move on to the next business. The only experience I've had with databases is some querying with SQL, and I've built GUI interfaces with JAVA. The information on the interface will be populated from Excel so workers know what businesses they are dealing with. I've done some research and I believe the best way to build this would be building a GUI using Microsoft Visual Studio (Visual Basic) first, then figuring out a way to populate the Interface from Excel. Also because the data is pretty straight forward and not complicated I will be using MS Access to store and track the database. I know this won't be easy, but for all you geniuses out there, is this on the right path? Thanks.

  • Why are PHP function signatures so inconsistent?

    - by Shamim Hafiz
    I was going through some PHP functions and I could not help notice the following: <?php function foo(&$var) { } foo($a); // $a is "created" and assigned to null $b = array(); foo($b['b']); var_dump(array_key_exists('b', $b)); // bool(true) $c = new StdClass; foo($c->d); var_dump(property_exists($c, 'd')); // bool(true) ?> Notice the array_key_exists() and property_exists() function. In the first one, the property name(key for an array) is the first parameter while in the second one it is the second parameter. By intuition, one would expect them to have similar signature. This can lead to confusion and the development time may be wasted by making corrections of this type. Shouldn't PHP, or any language for that matter, consider making the signatures of related functions consistent?

  • Books for MCSD and advice

    - by Mahesha999
    Hi there I am thinking to get certification done for MCSD. http://www.microsoft.com/learning/en/us/certification/cert-mcsd-web-applications.aspx I did found the books for first exam 480 comprising CSS3, HTML5 and JavaScript. However I did not found books for other exams: 486: ASP.NET MVC 4.5 Apps - Will ASP.NET 4 books suffice for this? Should I also learn Web Forms though I have considerable part of it. 487: Windows Azure and Web Services - What book should I use? I seems that the syllabus is too huge and will take considerable time. Anyone suggesting any advice to complete such exams, since this is going to be my first such. How should I prepare? Should I give this exam? Will it help? Sorry I know I asked many questions here in one questions - a bad practice but the books-question is a big concern for me.

  • RMS java web framework

    - by Kamil Tomšík
    We're currently reconsidering technologies and frameworks to get more agile with "simple" RMS CRUD-based projects. In short, short-living things like this Right now we have custom extension on top of SmartGWT but after some time it has proven not to be enough flexible. I also personally dislike that java-js compilation process and the whole GWT codebase. Not only its ugly designed, it also makes certain low-level js things very complicated if not completely impossible. So what I'm looking for is: closest to web as possible, like JSF or possibly Tapestry, it is very important to be able get "low" and weave framework if necessary. Happens more often than we thought. datagrid capable - Ext.js & PrimeFaces looks pretty good, Vaadin does too. db-schema generators (optional, no matter in which way) If it were only on me, I'd probably stick to Ext.js + custom rest-based java solution, possibly generated from database schema (not sure about concrete tooling yet) I only does have experience with vanilla Ext.js, vanilla GWT and JSF 2.0 / Seam, so it kinda hard for me to judge or even propose other frameworks. What would be your proposition? What are the problems you've faced, what was your solution and how hard do you think it was to deal with them in "big picture"?

  • Should each app have its own database, or should small apps be merged into one?

    - by King
    We have a bunch of small to medium sized apps, each of which has its own database (MSSQL Server). There was a suggestion that we consoldate the 'related' databases into a smaller set amount of larger databases. They don't particularly share a lot of data, they would just be under a similar business group. For example, using a 'Finance' DB to hold the tables and procedures for finance apps. Would it be appropriate to use a different schema for each app? E.g. App1.SomeTable App1.SomeOtherTable AppTwo.SomeTable What are the pros and cons of this approach? What should I watch out for? Thanks

  • Can an agile shop really score 12 on the Joel Test?

    - by Simon
    I really like the Joel test, use it myself, and encourage my staff and interviewees to consider it carefully. However I don't think I can ever score more than 9 because a few points seem to contradict the Agile Manifesto, XP and TDD, which are the bedrocks of my world. Specifically: the questions about schedule, specs, testers and quiet working conditions run counter to what we are trying to create and the values that we have adopted in being genuinely agile. So my question is: is it possible for a true Agile shop to score 12?

  • Learning Erlang vs learning node.js

    - by Noli
    I see a lot of crap online about how Erlang kicks node.js' ass in just about every conceivable category. So I'd like to learn Erlang, and give it a shot, but here's the problem. I'm finding that I have a much harder time picking up Erlang than I did picking up node.js. With node.js, I could pick a relatively complex project, and in a day I had something working. With Erlang, I'm running into barriers, and not going nearly as quickly. So.. for those with more experience, is Erlang complicated to learn, or am I just missing something? Node.js might not be perfect, but I seem to be able to get things done with it.

  • Are project managers useful in Scrum?

    - by Martin Wickman
    There are three roles defined in Scrum: Team, Product Owner and Scrum Master. There is no project manager, instead the project manager job is spread across the three roles. For instance: The Scrum Master: Responsible for the process. Removes impediments. The Product Owner: Manages and prioritizes the list of work to be done to maximize ROI. Represents all interested parties (customers, stakeholders). The Team: Self manage its work by estimating and distributing it among themselves. Responsible for meeting their own commitments. So in Scrum, there is no longer a single person responsible for project success. There is no command-and-control structure in place. That seems to baffle a lot of people, specifically those not used to agile methods, and of course, PM's. I'm really interested in this and what your experiences are, as I think this is one of the things that can make or break a Scrum implementation. Do you agree with Scrum that a project manager is not needed? Do you think such a role is still required? Why?

  • Why did Alan Kay say, "The Internet was so well done, but the web was by amateurs"?

    - by kalaracey
    OK, so I paraphrased. The full quote: The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free? The Web, in comparison, is a joke. The Web was done by amateurs. -- Alan Kay. I am trying to understand the history of the Internet and the web, and this statement is hard to understand. I have read elsewhere that the Internet is now used for very different things than it was designed for, and so perhaps that factors in. What makes the Internet so well done, and what makes the web so amateurish? (Of course, Alan Kay is fallible, and no one here is Alan Kay, so we can't know precisely why he said that, but what are some possible explanations?) *See also the original interview*.

  • Questions re: Eclipse Jobs API

    - by BenCole
    Similar to http://stackoverflow.com/questions/8738160/eclipse-jobs-api-for-a-stand-alone-swing-project This question mentions the Jobs API from the Eclipse IDE: ...The disadvantage of the pre-3.0 approach was that the user had to wait until an operation completed before the UI became responsive again. The UI still provided the user the ability to cancel the currently running operation but no other work could be done until the operation completed. Some operations were performed in the background (resource decoration and JDT file indexing are two such examples) but these operations were restricted in the sense that they could not modify the workspace. If a background operation did try to modify the workspace, the UI thread would be blocked if the user explicitly performed an operation that modified the workspace and, even worse, the user would not be able to cancel the operation. A further complication with concurrency was that the interaction between the independent locking mechanisms of different plug-ins often resulted in deadlock situations. Because of the independent nature of the locks, there was no way for Eclipse to recover from the deadlock, which forced users to kill the application... ...The functionality provided by the workspace locking mechanism can be broken down into the following three aspects: Resource locking to ensure multiple operations did not concurrently modify the same resource Resource change batching to ensure UI stability during an operation Identification of an appropriate time to perform incremental building With the introduction of the Jobs API, these areas have been divided into separate mechanisms and a few additional facilities have been added. The following list summarizes the facilities added. Job class: support for performing operations or other work in the background. ISchedulingRule interface: support for determining which jobs can run concurrently. WorkspaceJob and two IWorkspace#run() methods: support for batching of delta change notifications. Background auto-build: running of incremental build at a time when no other running operations are affecting resources. ILock interface: support for deadlock detection and recovery. Job properties for configuring user feedback for jobs run in the background. The rest of this article provides examples of how to use the above-mentioned facilities... In regards to above API, is this an implementation of a particular design pattern? Which one?

  • Softpedia published some of my open source projects — how to react?

    - by polarblau
    (FYI: I've just moved this question over from Stackoverflow on recommendation.) I just received a few emails, informing me that softpedia.com has added some of my "products" to their "database of scripts, code snippets and web applications". My products are in this case some smaller open source projects, which I have hosted and published on github. Now I'm wondering how to react to this. This site is indirectly making money of my free work through ads on three pages before the actual download. They also seem to "invent" version numbers and I can't find out if they're hosting the latest or all versions of my projects. — I can see how this could lead to problems in the future, since I don't control what's "the latest" everywhere. On the other hand I don't mind some extra publicity. I want as many people as possible to know about the projects, use them, fork them and hopefully improve them. The projects in questions are really fairly small, but this might not be the case in the future for me and/or other people reading this question. I'm sure that this must have happened to others around here. What's your opinion? Should I try to get the downloads removed? Update 1 I've requested the removal and mentioned that I don't feel that Softpedia can provide the right environment for this kind of project. Their team got back to me instantly with a friendly email saying, that they'll remove the links for now: If you are worried that your projects won't be updated, then I must tell you that I have them bookmarked in my RSS reader, so any version changes will be forwarded to me when needed. So I promise I'll keep your script up to date as soon as I see an update in the repository. I have to say, that I appreciate this kind of reaction quite a lot and so I sent them another email, describing in more detail what I'm worried about and what bothers me. I also stated, that I'm aware that my license clearly permits them to host the projects in any case, but that I'd be even happy if they would host the projects as long as they could convince me of a few details and maybe make some small changes to the way the projects are represented. — Let's see where this goes. Update 2 After discussing with their contact and requesting some changes regarding display of version (they had given the possibility to do so) and authorship they put the projects back up on their site. All in all a positive and definitely interesting experience.

  • Git Project Dependencies on GitHub

    - by VirtuosiMedia
    I've written a PHP framework and a CMS on top of the framework. The CMS is dependent on the framework, but the framework exists as a self-contained folder within the CMS files. I'd like to maintain them as separate projects on GitHub, but I don't want to have the mess of updating the CMS project every time I update the framework. Ideally, I'd like to have the CMS somehow pull the framework files for inclusion into a predefined sub-directory rather than physically committing those files. Is this possible with Git/GitHub? If so, what do I need to know to make it work? Keep in mind that I'm at a very, very basic level of experience with Git - I can make repositories and commit using the Git plugin for Eclipse, connect to GitHub, and that's about it. I'm currently working solo on the projects, so I haven't had to learn much more about Git so far, but I'd like to open it up to others in the future and I want to make sure I have it right. Also, what should my ideal workflow be for projects with dependencies? Any tips on that subject would also greatly appreciated. If you need more info on my setup, just ask in the comments.

  • How does I/O work for large graph databases?

    - by tjb1982
    I should preface this by saying that I'm mostly a front end web developer, trained as a musician, but over the past few years I've been getting more and more into computer science. So one idea I have as a fun toy project to learn about data structures and C programming was to design and implement my own very simple database that would manage an adjacency list of posts. I don't want SQL (maybe I'll do my own query language? I'm just having fun). It should support ACID. It should be capable of storing 1TB let's say. So with that, I was trying to think of how a database even stores data, without regard to data structures necessarily. I'm working on linux, and I've read that in that world "everything is a file," including hardware (like /dev/*), so I think that that obviously has to apply to a database, too, and it clearly does--whether it's MySQL or PostgreSQL or Neo4j, the database itself is a collection of files you can see in the filesystem. That said, there would come a point in scale where loading the entire database into primary memory just wouldn't work, so it doesn't make sense to design it with that mindset (I assume). However, reading from secondary memory would be much slower and regardless some portion of the database has to be in primary memory in order for you to be able to do anything with it. I read this post: Why use a database instead of just saving your data to disk? And I found it difficult to understand how other databases, like SQLite or Neo4j, read and write from secondary memory and are still very fast (faster, it would seem, than simply writing files to the filesystem as the above question suggests). It seems the key is indexing. But even indexes need to be stored in secondary memory. They are inherently smaller than the database itself, but indexes in a very large database might be prohibitively large, too. So my question is how is I/O generally done with large databases like the one I described above that would be at least 1TB storing a big adjacency list? If indexing is more or less the answer, how exactly does indexing work--what data structures should be involved?

  • The best Drupal and JavaScript developer?

    - by hakanito
    I've read a lot of JS articles and books by Nicholas Zakas and Addy Osmani, in my opinion evangelists in the field. But I am also a Drupal developer, and these guys are not. Many of the techniques they're talking about such as AMD and RequireJS are great, but it's hard to know how to integrate them when it comes to Drupal (and do it right, ofc). So my question is if there are any recognized developer/s out there with strong JavaScript AND Drupal experience?

  • Architecture for Social Graph data that has a Time Frame Associated?

    - by Jay Stevens
    I am adding some "social" type features to an existing application. There are a limited # of node & edge types. Overall the data itself is relatively small (50,000 - 70,000 for each type of node) there will be a number of edges (relationships) between them (almost all directional). This, I know, is relatively easy to represent with an SDF store (such as BrightstarDB) or something like Microsoft's Trinity (or really many of the noSQL options). The thing that, I think, makes this a unique use case is that each relationship will have a timeframe associated with it (start and end dates). Right now, I'm thinking of just storing this in a relational structure and dealing with the headaches of "traversing the graph", but I'm looking for suggestions on a better approach (both in terms of data structure and server): Column ================ From_Node_ID Relationship To_Node_ID StartDate EndDate Any suggestions or thoughts are welcomed.

  • If I define a property to prototype appears in the constructor of object, why?

    I took the example from this question modified a bit: What is the point of the prototype method? function employee(name,jobtitle,born) { this.name=name; this.jobtitle=jobtitle; this.born=born; this.status="single" } employee.prototype.salary=10000000; var fred=new employee("Fred Flintstone","Caveman",1970); console.log(fred.salary); fred.salary=20000; console.log(fred.salary) And the output in console is this: What is the difference salary is in constructor but I still can access it with fred.salary, how can I see if is in constructor from code, status is still employee property how can I tell for example if name is the one of employee or has been touch by initialization? Why is salary in constructor, when name,jobtitle,born where "touched" by employee("Fred Flintstone","Caveman",1970); «constructor»?

  • Entity Framework with large systems - how to divide models?

    - by jkohlhepp
    I'm working with a SQL Server database with 1000+ tables, another few hundred views, and several thousand stored procedures. We are looking to start using Entity Framework for our newer projects, and we are working on our strategy for doing so. The thing I'm hung up on is how best to split the tables into different models (EDMX or DbContext if we go code first). I can think of a few strategies right off the bat: Split by schema We have our tables split across probably a dozen schemas. We could do one model per schema. This isn't perfect, though, because dbo still ends up being very large, with 500+ tables / views. Another problem is that certain units of work will end up having to do transactions that span multiple models, which adds to complexity, although I assume EF makes this fairly straightforward. Split by intent Instead of worrying about schemas, split the models by intent. So we'll have different models for each application, or project, or module, or screen, depending on how granular we want to get. The problem I see with this is that there are certain tables that inevitably have to be used in every case, such as User or AuditHistory. Do we add those to every model (violates DRY I think), or are those in a separate model that is used by every project? Don't split at all - one giant model This is obviously simple from a development perspective but from my research and my intuition this seems like it could perform terribly, both at design time, compile time, and possibly run time. What is the best practice for using EF against such a large database? Specifically what strategies do people use in designing models against this volume of DB objects? Are there options that I'm not thinking of that work better than what I have above? Also, is this a problem in other ORMs such as NHibernate? If so have they come up with any better solutions than EF?

  • How to deal with colleagues refuse to follow practices?

    - by Adrian Shum
    I was discussing with another colleague about what we should be used when an DB entity is referring to another. I don't think there is any good reason to break the practice of putting the Primary Key in the referring entity. However, one of my colleague says: "You should use a surrogate key in the entity, but it is better to put the human-readable natural key in the referring entity. As long it is unique, it is fine and it is easier when you are doing support or maintenance job" I know it will works, but obviously it is not a good practice you are putting a non-PK unique column as "foreign key", just for gaining a bit of ease in writing SQL during support as we can have less table join. Though I mentioned the his approach is conceptual incorrect, and causing problem too practically etc, he seems rather trade off correctness in data model in exchange of ease of maintenance. And he said: "I know it is not good practice, but good practice is not golden rule" Honestly I feel frustrated when dealing with something like this.
