• Business/Development Liaison Wanting To Enhance Understanding In Programming

  - by James Alexander

  I lead software development for a team of of about 20 devs and we're primarily a .net/sql server shop. We've recently created a new role in our organization for a more business like role to assist in prioritization of development and this business liaison has asked me if there are any books or resources he could use to better understand software concepts in a meaningful way. Any suggestions or advice would be greatly appreciated.

• 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?

• 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?

• Visualize flowchart diagram with multiple end symbols

  - by platzhirsch

  I am looking for a standardize way to visualize the following hierarchical logic: The state of the thread is represented by the answers to the hierarchical set of question You can read this listing like a flowchart, you iterate over the questions decide, go one step deeper and so on. Therefore I thought the best way to visualize it, using a flowchart. The problem is, in this hierarchical set it is possible to end in more than one state and its totally valid. I have never seen a flowchart where you can enter more than one state. Is it still possible and I am missing the right symbol to present this logic or are flowchart not fitting anyway? What other graphical representation could I use, is there something fitting in UML? A non-deterministic state machine seems not to be intuitive enough, transfering it into a deterministic state machine would result in to many states, and so on.

• 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.

• 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)

• C++ : Lack of Standardization at the Binary Level

  - by Nawaz

  Why ISO/ANSI didn't standardize C++ at the binary level? There are many portability issues with C++, which is only because of lack of it's standardization at the binary level. Don Box writes, (quoting from his book Essential COM, chapter COM As A Better C++) C++ and Portability Once the decision is made to distribute a C++ class as a DLL, one is faced with one of the fundamental weaknesses of C++, that is, lack of standardization at the binary level. Although the ISO/ANSI C++ Draft Working Paper attempts to codify which programs will compile and what the semantic effects of running them will be, it makes no attempt to standardize the binary runtime model of C++. The first time this problem will become evident is when a client tries to link against the FastString DLL's import library from a C++ developement environment other than the one used to build the FastString DLL. Are there more benefits Or loss of this lack of binary standardization?

• 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!!

• 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

• 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.

• Learning frameworks without learning languages

  - by Tom Morris

  I've been reading up on GUI frameworks including WPF, GTK and Cocoa (UIKit). I don't really do anything related to Windows (I'm a Mac and Linux guy) or .NET, but I'd like to be able to throw together GUIs for various operating systems. We are in the enviable position now of having high level scripting languages that work with all of the major GUI toolkits. If you are doing Linux GUI programming, you could use GTK in C, but why not just use PyGTK (or PyQt). Similarly, for Java, one can use JRuby. For Mac, there's MacRuby. And on .NET, there's IronRuby. This is all fine and good, and if you are building a serious project, there are tradeoffs that you might encounter when deciding whether to, say, build a WPF app in C# or in IronRuby, or whether you are going to use PyGTK or not. The subjective question I have is: what about learning those frameworks? Are there strong reasons why one should or should not learn something like WPF or Cocoa in a language one is familiar with rather than having to learn a new language as well? I'm not saying you should never learn the language. If you are building Windows applications and you don't know C#, that might be a bit of a problem. But do you think it is okay to learn the framework first? This is both a general question and a specific question. I've used some Cocoa classes from Ruby and Python using things like PyObjC and there always seems to be an impedance mismatch because of the way Objective C libraries get built. Experiences and strong opinions welcome!

• 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?

• How to use TCP/IP Nagle algorithm at Apple Push Notification

  - by Mahbubur R Aaman

  From Apple's Developer Library The binary interface employs a plain TCP socket for binary content that is streaming in nature. For optimum performance, you should batch multiple notifications in a single transmission over the interface, either explicitly or using a TCP/IP Nagle algorithm. How to use TCP/IP Nagle algorithm in case Apple's Push Notification? How to batch multiple notification in a single transmission over the interface? Additional # In Apple's Push Notification Urban Airship is a familiar name to send large amount of push notification within several minutes. Does they use TCP/IP Nagle algorithm?

• 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?

• 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.

• 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#.

• 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.

• 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.

• 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

• 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?

• 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?

• 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? )

• 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?

• What strategies you followed to keep your programming skills fresh during a long break?

  - by TRoh

  After being away from development for more than a year, I find it challenging to join back the work force, and I can feel the rustiness. I wonder what you have done to either keep your skills fresh during such periods or how you gained back the skills you might have forgotten? I understand coding is a great way to become more competent, but how do you start getting more involved in it while you are not working as a developer?
