At the company that I work we have a successful software product that did well but is now obsolete and unmaintainable. I am trying to explain that you need to innovate and replace this product with new offering in order to survive. I am looking for some good examples of companies that made the mistake that we are close to making - relyin...
I'm trying to implement the strategy pattern using TDD. Each strategy item implements an interface. What's the best way to do this with TDD? Do you have to create a test fixture for each implementation of the interface testing the same methods but on each implementation? Any articles detailing the approach to take would be gratefully w...
I am working on a regular iPhone app which pulls data from a server (XML, JSON, etc...), and I'm wondering what is the best way to implement synching data. Criteria are speed (less network data exchange), robustness (data recovery in case update fails), offline access and flexibility (adaptable when the structure of the database changes ...
The substance of an app is more important to me than its apperance, yet GUI always seems to dominate a disproportionate percentage of programmer time, development and target resource requirements/constraints. Ideally I'd like an application architecture that will permit me to develop an app using a lightweight reference GUI/kit and foc...
I'm building an ASP.NET MVC site where I want to have a Google Maps Javascript API map that shows markers loaded from my backend through AJAX. As I don't want the client to run into memory issues, I want to lazy-load the markers and apply them to Fluster2 to put them into clusters. I think the best way to lazy-load the markers is to add...
In the code where I work, we got many think like that : if (user.HasRight("Profile.View")) {} So, there is many place where we pass a string as parameter to see if the user have a specific right. I don't like that because that generate a lot of magic string. What would be a better way of doing it ? Enum, Constant, class ? ...
For computing Income Tax, I tried to use Enum Strategy approach to make the logic more concise. But in the end I’m not satisfied mainly because I had to write different enums for income groups, limits and rates. This was because they are all constants of different nature. But due to this the code doesn’t looks compact and seems to lack e...
A web application contains sensitive data of the users. Neither the operator of the web application nor the hosting provider should be able to see this data. Therefore I wanted to store these data in the DB encrypted with the entrance password of the users. dataInDB = encrypt (rawData, user password) With this strategy it is however...
Say we have three dependent select dropdowns (selecting parent asynchronously populates the child via a database query): DD1: [People of this world] DD2: [Hair Strands] DD3: [Keratin Molecules] Ok, our options' lists won't be as large as what the names here imply, but each dropdown is going to house about 1 million option i...
I have an Flash/Flex application that is showing weird behavior when used in conjunction with international keyboards. For example, I have extended TextInput in this app to allow for special behavior when the user presses the hyphen ('-') key. When this happens I want the text of the input to be padded with zeros in addition to the typ...
Hey i need some general advice on how to structure my project. i am trying to make a simple strategygame where some object move around in a "worldspace" and youve got several different tactical views, which show diffent areas of the game. nothing special. but since i'm a rather unexperienced programmer, some things are not quiet clear to...
Hi, Consider that you have "System_A" which is a web application. And System_A has simply 3 layers: UI, BusinessLayer and Data-Layer. And now you want to make a widespread refactoring of System_A (the UI and BusinessLayer only) meanwhile that is working as a live product. What should be the safest strategy of refactoring System_A and ...
I've got a class that serializes data. I may want to serialize this data as JSON, or perhaps YAML. Can I cleanly swap YAML for JSON objects in this case? I was hoping I could do something like the following. Is it a pipe dream? FORMATS = { :json => JSON, :yaml => YAML, } def serialize(data, format) FORMATS[format].serialize(data)...
Hi guys, I've been working at my university this summer in an image/video lab. Just recently, my professor gave me a program written by a grad student who just left the program to "fix up", because it was "giving some errors." The project was written in C++ (seems to be a recurring bad sign in student code). I opened the project in VS0...
Hi, I'm using asynchronous methods in my service (Spring 3 @Async annotation). And I've got a problem - spawned thread doesn't have security context. Cause of it is Spring Security by default uses SecurityContextHolder.MODE_THREADLOCAL strategy for its context holder. But I need to use SecurityContextHolder.MODE_INHERITABLETHREADLOCAL s...
Hi, i've a Drupal theory/strategy related question. First i want to say that i'm very new to the drupalling world, so this question can be quiet stupid. I'm trying to develop/make a part of a site that has the following structure: (level one) virtual_exhibitions: shows an overview of exhibition categories. (level two) themes, places, p...
What is the right format for a git merge with a strategy of recursive ours? (not to be confused with the git merge ours strategy) http://www.kernel.org/pub/software/scm/git/docs/git-merge.html I tried a bunch of ways and it doesn't seem to work. git merge foo -s recursive-ours // doesn't work git merge foo -s recursive ours // doesn...
This question is not Perl-specific, (although the unpack function will most probably figure into my implementation). I have to deal with files where multiple formats exist to hierarchically break down the data into meaningful sections. What I'd like to be able to do is parse the file data into a suitable data structure. Here's an examp...
Hi, What would you advice to a development team that is about to move to a new technology (Let's say from asp.net application to SilverLight where no one in the team has an experience so far on SL development, or for a similar case)? How should be the learning, experiencing, planning, development and other phases should be orchestrated...
Hello! I'm trying to implement my own Hibernate NamingStrategy based on the ImprovedNamingStrategy. This is quite nice... only the foreign keys of many-to-many relations are ugly. Example scenario: public class Teacher { @ManyToMany private Set<Course> courses; } public class Course { @ManyToMany private Set<Teacher> ...
