  • Triggering custom events in AJAX callbacks

    - by Sabrina Gelbart
    I'm pretty new to JavaScript, but one of the things that's been frustrating is that our AJAX callbacks have been getting packed with different functionality, making it difficult to keep everything separated and organized. I'm really new to programming, I have a feeling learning MVC a bit more would help me, but for now using custom events seems like it could help me keep my code a lot cleaner and prevent some problems. Here's what I'm talking about: function myAjaxFunction(){ $.post('ajax/test.html', function(data) { $(document).trigger('testDataLoaded',data); }); } function myOtherFunctionThatsDependentUponAjax(){ $(document).one('testDataLoaded', function(data){ alert (data); } } I also don't know if it's ok that I'm triggering document or not... Are there any patterns that look like this that I can read more about? What are the potential problems with this?

  • Why do we need fork to create new process

    - by user3671483
    In Unix whenever we want to create a new process, we fork the current process i.e. we create a new child process which is exactly the same as the parent process and then we do exec system call to replace the child process with a new process i.e. we replace all the data for the parent process eith that for the new process. Why do we create a copy of the parent process in the first place and why don't we create a new process directly? I am new to Unix please explain in lay-man terms.

  • When should I use—and not use—design patterns?

    - by ashmish2
    In a previous question of mine on Stack Overflow, FredOverflow mentioned in the comments: Note that patterns do not magically improve the quality of your code. and Any measure of quality you can imagine. Patterns are not a panacea. I once wrote a Tetris game with about 100 classes that incorporated all the patterns I knew at the time. Why use a simple if/else if you can use a pattern? OO is good, and patterns are even better, right? No, it was a terrible, over-engineered piece of crap. I am quite confused by these comments: I know design patterns help to make code reusable and readable, but when should I use use design patterns and perhaps more importantly, when should I avoid getting carried away with them?

  • printable PHP manual - 'all but the Function Reference section'

    - by JW01
    My Motivation I find it easier to learn things by reading 'offline'. I'd like to lean back and read the narrative part of a paper version of the official php manual. My Scuppered Plan My plan was to download the manual, print all but the Function Reference section and then read it. I have downloaded the "Single HTML file" version of the manual from the php.net download page. (That version did not contain any images, so I patched-in the ones from the Many HTML files version with no problem.) My plan was to open that "Single HTML file" in an HTML editor, delete the Function Reference section then print it out. Unfortunately, although I have tried three different editors, I have not been able to successfully load-up that massive html file to be able to edit it. Its about (~40MB). I started to look into the phpdoc framework with a view to rendering my own html docs from the source...but that's a steep learning curve for a newby..and is a last resort. I would use a file splitter, but they tend to split files crudely with no regard for html/xml/xhtml sematics. So the question is... Does anyone know know where you can download the php manual in a version that is a kind of half-way house between the 'Single HTML file' and the 'Many HTML files'? Ideally with the docs split into 3 parts: File 1 - stuff before the function reference File 2 - function reference File 3 - stuff after the function reference Or Can you suggest any editors/tools will enable me to split up this file myself?

  • Mapping between 4+1 architectural view model & UML

    - by Sadeq Dousti
    I'm a bit confused about how the 4+1 architectural view model maps to UML. Wikipedia gives the following mapping: Logical view: Class diagram, Communication diagram, Sequence diagram. Development view: Component diagram, Package diagram Process view: Activity diagram Physical view: Deployment diagram Scenarios: Use-case diagram The paper Role of UML Sequence Diagram Constructs in Object Lifecycle Concept gives the following mapping: Logical view (class diagram (CD), object diagram (OD), sequence diagram (SD), collaboration diagram (COD), state chart diagram (SCD), activity diagram (AD)) Development view (package diagram, component diagram), Process view (use case diagram, CD, OD, SD, COD, SCD, AD), Physical view (deployment diagram), and Use case view (use case diagram, OD, SD, COD, SCD, AD) which combines the four mentioned above. The web page UML 4+1 View Materials presents the following mapping: Finally, the white paper Applying 4+1 View Architecture with UML 2 gives yet another mapping: Logical view class diagrams, object diagrams, state charts, and composite structures Process view sequence diagrams, communication diagrams, activity diagrams, timing diagrams, interaction overview diagrams Development view component diagrams Physical view deployment diagram Use case view use case diagram, activity diagrams I'm sure further search will reveal other mappings as well. While various people usually have different perspectives, I don't see why this is the case here. Specially, each UML diagram describes the system from a particular aspect. So, for instance, why the "sequence diagram" is considered as describing the "logical view" of the system by one author, while another author considers it as describing the "process view"? Could you please help me clarify the confusion?

  • Switch interface implementation using configuration

    - by Marcos
    We want to allow the same core service to be either fully implemented or, as other option, to be a proxy toward a client legacy system (via a WSDL for example). In that way, we have both implementation (proxy & full) and we switch which one to use in the configuration of the app. So in a nutshell, Some desired features: Two different implementation (proxy, full) instead of one implementation with a switch inside Switch implementation using configuration: dependency injection? reflection? Nice-to-have: the packaged delivered to the client doesn’t have to change depending on the choice between proxy or full Nice-to-have: Client can develop their custom implementation of the Core Interface and configure the applciation to use that one With this background, the question is: What alternatives we have to choose one implementation or other of an interface just changing configuration? Thanks

  • Where to find clients?

    - by Zenph
    Of course, I don't expect anybody give away their 'gold mine' or whatever but I am struggling to see where I should be advertising my services. I have one other developer I work with and we have a lot of happy clients - on freelance websites. Thing is, freelance websites just seem to suck the life out of you when you're being out-bidded by ridiculous rates. I want to attract customers who are more concerned about quality and accountability than price. Any suggestions at all? I'm so lost with this.

  • Going into Web Development without a C.S. Degree - Suggestions

    - by Klaint Cokeman
    I plan on seeking a career in web development and I'm about two semesters away from graduating with a CIS degree. Although I'm very satisfied with my choice of degree, I'm concerned that I may be lacking knowledge in a few areas because of not majoring in computer science. The programming side of things is no problem for me, I'm just wondering to what extent data structures/theory/etc. might benefit me to learn over spending more time with hands-on programming... and also what aspects of C.S. would be most appropriate to look into you would think would be most applicable to web development. In short, I'd like to expand my horizons a little bit. I'd very much appreciate and advice/suggestions/book or tutorial recommendations, etc. Thanks.

  • Why do you need float/double?

    - by acidzombie24
    I was watching http://www.joelonsoftware.com/items/2011/06/27.html and laughed at Jon Skeet joke about 0.3 not being 0.3. I personally never had problems with floats/decimals/doubles but then I remember I learned 6502 very early and never needed floats in most of my programs. The only time I used it was for graphics and math where inaccurate numbers were ok and the output was for the screen and not to be stored (in a db, file) or dependent on. My question is, where are places were you typically use floats/decimals/double? So I know to watch out for these gotchas. With money I use longs and store values by the cent, for speed of an object in a game I add ints and divide (or bitshift) the value to know if I need to move a pixel or not. (I made object move in the 6502 days, we had no divide nor floats but had shifts). So I was mostly curious.

  • How do you decide site availability requirements?

    - by Nathan Long
    I work on a web application to file a specific kind of county taxes. Our company wants our state to mandate that counties must accept electronic filings (as opposed to paper) from any system that meets some sensible requirements for uptime, security, data validation, etc. (Yes, this would help us as a business, but it would also force county governments to be more efficient.) We're creating a draft of those requirements to be reviewed and tweaked with the state. One of the sections is "availability." We want to specify something reasonably high, but not so high that any unexpected problem will get us (or a competitor) penalized. How do we decide what's reasonable for availability requirements?

  • Teamwork 101 for the solo newbie

    - by clankercrusher
    Forgive my newbishness but I have a question to ask about teamwork...mainly because I stink at it. Most of my projects up until this point have been solo so I have a very limited experience with teamwork. I did make graphics for a game that was being developed by several people, but that was completely different than programming with several different people. Right now I'm working with someone else on an indie MMO along with a few other team members. I've already made some pretty stupid mistakes, (like rewriting EVERYTHING) so I have two questions for you guys: 1) What are some of the most common mistakes that people make in a team environment and how can they be avoided? 2) How can the structure of your program be altered to allow for multiple teams members to work on different parts of the program at the same time? P.S. Is this the right stack exchange site for this type of question? (if not, where does it go? Thanks)

  • How do I resolve a plugin conflict in Eclipse?

    - by Jason Thompson
    I'd like to upgrade my Helios installation of Eclipse to Indigo. When I do, I get the following message: Cannot complete the install because of a conflicting dependency. Software being installed: Eclipse IDE for Java EE Developers 1.4.2.20120213-0813 (epp.package.jee 1.4.2.20120213-0813) Software currently installed: Oracle GlassFish Server Tools 1.6.1.201009290929 (oracle.eclipse.tools.helios.glassfish.feature.group 1.6.1.201009290929) So my first thought was to simply uninstall GlassFish. For the life of me, I can't figure out how and where to go to do this. I went to Help-About Eclipse...-Installation Details. The only place that it looks like I can uninstall stuff is in the "Installed Software" tab. I do not see the Oracle Glassfish package anywhere. If I go to "Feature" or "Plug-ins", I can find it just fine, but there is no option to uninstall. So my next thought was to upgrade Glassfish. So I put the indigo repo in there, but I still get the same message when trying to update. Any ideas?

  • What is spreadsheet useful for?

    - by zvrba
    I have been in computer business for 15 years in various roles (sysadmin, developer, researcher), and I have never encountered someone using excel for something more advanced than for formatting tables, or as an ad-hoc database that could have been maintained in a text-file. I had to do heavy data-processing and plotting and for that I used some perl scripts + gnuplot, got tiredof it, and went over to R eventually. 2D spreadsheet just didn't seem well-suited for doing statistical analyses over 5-dimensional datasets (not to mention that it produces UGLY plots). I attempted to use spreadsheet for time-tracking, and found out that I would have better been served by a relational database, so I gave up on using excel for that too. For example, it's important to consistently name tasks, and I needed to find out unique task names in a given column across several sheets (I had one timesheet for each month). How do you make such "query" in a program that essentially evaluates independent cells and has little notion of relations between them? So, what are spreadsheets useful for? Why do they have a bunch of mathematical stuff built into them when, AFAICT, people use them mostly as table formatters or bad substitutes for databases?

  • NLP - Queries using semantic wildcards in full text searching, maybe with Lucene?

    - by Zsolt
    Let's say I have a big corpus (for example in english or an arbitrary language), and I want to perform some semantic search on it. For example I have the query: "Be careful: [art] armada of [sg] is coming to [do sg]!" And the corpus contains the following sentence: "Be careful: an armada of alien ships is coming to destroy our planet!" It can be seen that my query string could contain "semantic placeholders", such as: [art] - some placeholder for articles (for example a / an in English) [sg], [do sg] - some placeholders for NPs and VPs (subjects and predicates) I would like to develop a library which would be capable to handle these queries efficiently. I suspect that some kind of POS-tagging would be necessary for parsing the text, but because I don't want to fully reimplement an already existing full-text search engine to make it work, I'm considering that how could I integrate this behaviour into a search engine like Lucene? I know there are SpanQueries which could behave similarly in some cases, but as I can see, Lucene doesn't do any semantic stuff with stored texts. It is possible to implement a behavior like this? Or do I have to write an own search engine?

  • Genetic algorithms with large chromosomes

    - by Howie
    I'm trying to solve the graph partitioning problem on large graphs (between a billion and trillion elements) using GA. The problem is that even one chromosome will take several gigs of memory. Are there any general compression techniques for chromosome encoding? Or should I look into distributed GA? NOTE: using some sort of evolutionary algorithm for this problem is a must! GA seems to be the best fit (although not for such large chromosomes). EDIT: I'm looking for state-of-the-art methods that other authors have used to solved the problem of large chromosomes. Note that I'm looking for either a more general solution or a solution particular to graph partitioning. Basically I'm looking for related works, as I, too, am attempting using GA for the problem of graph partitioning. So far I haven't found anyone that might have this problem of large chromosomes nor has tried to solve it.

  • Ur/Web new purely functional language for web programming?

    - by Phuc Nguyen
    I came across the Ur/Web project during my search for web frameworks for Haskell-like languages. It looks like a very interesting project done by one person. Basically, it is a domain-specific purely functional language for web programming, taking the best of ML and Haskell. The syntax is ML, but there are type classes and monad from Haskell, and it's strictly evaluated. Server-side is compiled to native code, client to Javascript. See the slides and FAQ page for other advertised advantages. Looking at the demos and their source code, I think the project is very promising. The latest version is something 20110123, so it seems to be under active development at this time. My question: Has anybody here had any further experience with it? Are there problems/annoyances compared to Haskell, apart from ML's slightly more verbose syntax? Even if it's not well known yet, I hope more people will know of it. OMG this looks very cool to me. I don't want this project to die!!

  • Object model design: collections on classes

    - by Luke Puplett
    Hi all, Consider Train.Passengers, what type would you use for Passengers where passengers are not supposed to be added or removed by the consuming code? I'm using .NET Framework, so this discussion would suit .NET, but it could apply to a number of modern languages/frameworks. In the .NET Framework, the List is not supposed to be publicly exposed. There's Collection and ICollection and guidance, which I tend to agree with, is to return the closest concrete type down the inheritance tree, so that'd be Collection since it is already an ICollection. But Collection has read/write semantics and so possibly it should be a ReadOnlyCollection, but its arguably common sense not to alter the contents of a collection that you don't have intimate knowledge about so is it necessary? And it requires extra work internally and can be a pain with (de)serialization. At the extreme ends I could just return Person[] (since LINQ now provides much of the benefits that previously would have been afforded by a more specified collection) or even build a strongly-typed PersonCollection or ReadOnlyPersonCollection! What do you do? Thanks for your time. Luke

  • Which Python Framework and CMS coming from PHP - Codeigniter+ExpresionEngine?

    - by Joshua Fricke
    We are currently developing most of our applications in PHP using CodeIgniter (CI) and ExpressionEngine (EE) and are looking to try our hands at Python. So we are looking for a Framework and ideally a CMS that work well together like the CI+EE combo does. Have done a bit of research, it looks like these are some good suggestions (though we are not limiting to these): Frameworks - http://wiki.python.org/moin/WebFrameworks Django Web2py CMS - http://wiki.python.org/moin/ContentManagementSystems Below picked because they are developed with a Framework (my only frame of reference using CI+EE) Merengue Mezzanine Django CMS Input would be great in helping us decide.

  • What functionality does dynamic typing allow?

    - by Justin984
    I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is under what circumstances it would be preferred. It is flexible and readable, but at the expense of more runtime checks and additional required unit testing. Aside from non-functional criteria like flexibility and readability, what reasons are there to choose dynamic typing? What can I do with dynamic typing that isn't possible otherwise? What specific code example can you think of that illustrates a concrete advantage of dynamic typing?

  • If some standards apply when "it depends" then should I stick with custom approaches?

    - by Travis J
    If I have an unconventional approach which works better than the industry standard, should I just stick with it even though in principal it violates those standards? What I am talking about is referential integrity for relational database management systems. The standard for enforcing referential integrity is to CASCADE delete. In practice, this is just not going to work all the time. In my current case, it does not. The alternative suggested is to either change the reference to NULL, DEFAULT, or just to take NO ACTION - usually in the form of a "soft delete". I am all about enforcing referential integrity. Love it. However, sometimes it just does not fully apply to use all the standards in practice. My approach has been to slightly abandon a small part of one of those practices which is the part about leaving "hanging references" around. Oops. The trade off is plentiful in this situation I believe. Instead of having deprecated data in the production database, a splattering of "soft delete" logic all across my controllers (and views sometimes depending on how far down the chain the soft delete occurred), and the prospect of queries taking longer and longer - instead of all that - I now have a recycle bin and centralized logic. The only tradeoff is that I must explicitly manage the possibility of "hanging references" which can be done through generics with one class. Any thoughts?

  • Who practices, or is likely to practice, the IEEE Software Engineering? [closed]

    - by user72757
    There is an interesting issue in Software Engineering which I'd like to explore. The issue is firstly what is and what is not software engineering. Secondly, if software engineering is what the IEEE defines it to be, what are good examples of companies which practice the SE? Detailed question: Software engineering (SE) is the application of a systematic, disciplined, quantifiable approach to the design, development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software. [updated definition, originating in 610.12-1990 - IEEE Standard Glossary of Software Engineering Terminology] If we consider as SE only those approaches that 100% match the above definition, we naturally get to SWEBOK (Software Engineering Body of Knowledge) which is created by the IEEE and the ACM. I'm seeking the answer to this: How can I find a company outside the defence industry which practices the SE as defined by IEEE? Clues: SE originates in 1968 NATO conference. The Software Engineering Institute (SEI) is based in the US at Carnegie Mellon University. Funding of the SEI is largely done by the US DoD. Defence industry uses the SE and sometimes has a partnership with the IEEE (as in case of Boeing). Possible decomposition of my big question into smaller chunks: a) Where is anyone who acknowledges the IEEE Software Engineering standards at work and perhaps even uses some of them? http://cs.hbg.psu.edu/cmpsc487/IEEEStds_List.htm b) Where can I find a person or a company building around SWEBOK? http://www.computer.org/portal/web/swebok/html/contents c) What is an example of a company professionally using CSDP (apart from those at IEEE website)? Does anyone have any possible contribution to this question?

  • Does programming knowledge have a half-life?

    - by Gary Rowe
    In answering this question, I asserted that programming knowledge has a half-life of about 18 months. In physics, we have radioactive decay which is the process by which a radioactive element transforms into something less energetic. The half-life is the measure of how long it takes for this process to result in only half of the material to remain. A parallel concept might be that over time our programming knowledge ceases to be the current idiom and eventually becomes irrelevant. Noting that a half-life is asymptotic (so some knowledge will always be relevant), what are your thoughts on this? Is 18 months a good estimate? Is it even the case? Does it apply to design patterns, but over a longer period? What are the inherent advantages/disadvantages of this half-life? Update Just found this question which covers the material fairly well: "Half of everything you know will be obsolete in 18-24 months" = ( True, or False? )

  • Don't Use "Static" in C#?

    - by Joshiatto
    I submitted an application I wrote to some other architects for code review. One of them almost immediately wrote me back and said "Don't use "static". You can't write automated tests with static classes and methods. "Static" is to be avoided." I checked and fully 1/4 of my classes are marked "static". I use static when I am not going to create an instance of a class because the class is a single global class used throughout the code. He went on to mention something involving mocking, IOC/DI techniques that can't be used with static code. He says it is unfortunate when 3rd party libraries are static because of their un-testability. Is this other architect correct? update: here is an example: APIManager - this class keeps dictionaries of 3rd party APIs I am calling along with the next allowed time. It enforces API usage limits that a lot of 3rd parties have in their terms of service. I use it anywhere I am calling a 3rd party service by calling Thread.Sleep(APIManager.GetWait("ProviderXYZ")); before making the call. Everything in here is thread safe and it works great with the TPL in C#.

  • What Contents in a Young Programmer's Personal Website

    - by DotNetStudent
    I recently stumbled upon this question in which the contents a professional programmer's website should have were discussed and I agree with most of the answers there. However, I am by no means a professional programmer (just came out from university) and so I am a bit lost in what concerns the contents I should provide in the personal website I am designing for myself now. I do have a pretty nice job at a fast-growing software company but I would really like to present myself to the outside world in a nice but humble manner since my curriculum is by no means a long one. Any ideas?
