• Looking for Application Framework Features Lists, Comparisons and Guides [closed]

  - by Blah McBlah

  I am looking for lists of the things that application frameworks can do and for websites that have matrices, marketing content, blog articles and whatnot for comparing application frameworks to each other or just selling a framework. I'm talking generally, so regardless of coded language or operating system or client device. I want it all. I've found a few online, and would appreciate whatever sources I can glean from this site too.

• Which iPhone ad API has produced the highest revenue for you?

  - by Kyle Humfeld

  This isn't a technical question, but more of a request for advice and empirical/anecdotal data. I'm nearly done writing a free app for iPhone, and I'm at the stage where I'm going to put ads into the app. I've had mixed success in the past with iAd (their fill rates have been atrocious recently, and their payouts have cut by about 75% over the past 4 months or so), and would like to know how much ad revenue you, the community, has seen from the various ad APIs you've used for your iPhone apps. This isn't a request for opinion, i.e. which is 'better', only what kinds of numbers you're seeing. I don't need absolute figures, but 'iAd pays x% higher than AdMob, and y% lower than AdSense' would be extremely helpful to me as I make my decision as to which ad API to integrate into my App. Also, have you had any experience or success with integrating multiple ad APIs into the same app? That's something I'm considering doing in my current iAd-filled apps (particularly my iPad app, which has yet to receive a single impression after nearly 60,000 requests)... something like: 1) Request-from-iAd 2) if that fails, request-from-adSense 3) if that fails, request-from-adMob 4) if that fails, ... etc.

• How do I improve my code reading skills

  - by Andrew

  Well the question is in the title - how do I improve my code reading skills. The software/hardware environment I currently do development in is quite slow with respect to compilation times and time it takes the whole system to test. The system is quite old/complex and thus splitting it into a several smaller, more manageable sub-projects is not feasible in a neare future. I have realized is what really hinders the development progress is my code reading skills. How do I improve my code reading skills, so I can spot most of the errors and issues in the code even before I hit the "do compile" key, even before I start the debugger?

• Why learning new things is not important on a job hunt? [closed]

  - by IAdapter

  I have just finished my job hunt. I think it was about 40 job interviews, I like to travel and get to know many companies. One thing I did not like is that they don't care about new technologies. I think only 2 persons asked me about new stuff in Java world. Most of them care if I know Java (certification and many years of experiance is not enough for them, they need to test me) For example in IBM they only cared what IBM products do I know. Have I ever used any custom extensions of WebSphere? I don't understand those questions. If I learn new frameworks every day then I can learn whatever technology they have very fast. So why it matters if I have ever used those "great" custom extensions of WebSphere? After those 40 interviews I have no reason to learn any new framework, because I see that they don't care. Why those "developers" don't ask questions about new technologies? are they so long at those comapnies that they don't care about new stuff?

• Using a :default for file names on include templates in SMARTY 3 [closed]

  - by Yohan Leafheart

  Hello everyone, Although I don't think the question was as good as it could be, let me try to explain better here. I have a site using SMARTY 3 as the template system. I have a template structure similar to the below one: /templates/place1/inner_a.tpl /templates/place1/inner_b.tpl /templates/place2/inner_b.tpl /templates/place2/inner_c.tpl /templates/default/inner_a.tpl /templates/default/inner_b.tpl /templates/default/inner_c.tpl These are getting included on the parent template using {include file="{$temp_folder}/{$inner_template}"} So far great. What I wanted to do is having a default for, in the case that the file "{$temp_folder}/{$inner_template}" does not exists, it uses the equivalent file at "default/{$inner_template}". i.e. If I do {include file="place1/inner_c.tpl"}, since that file does not exists it in fact includes "default/inner_c.tpl" Is it possible?

• Best way to use GIT to maintain web application template

  - by Darren

  I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

• Where's Randall Hyde?

  - by user1124893

  This probably doesn't belong here, but I couldn't think of any other StackExchange site that would fit it. Quick question, what ever happened to Randall Hyde, author of The Art of Assembly, HLA, and other works? I ask this because I was just exploring some of the content on his website and a lot of it is now gone. His website was hosted on Apple's MobileMe. As of the writing of this question, Apple has closed off all MobileMe content a few days ago. Correct me if I'm wrong, but didn't Apple warn of this a year in advance? If so, then where's Randall Hyde? Come to think of it, all of the content on his website that I have seen is several years old. A lot of it is rather useful but unfinished.

• How do I explain to HR that my work experience is relevant even if it doesn't match the keywords in the job description?

  - by Dmitri

  I am looking at a job with a great company and in a field that I really want to be in. Unfortunalty, what they want is someone with "experience with ASP (VB), T-SQL in a production environment." But I've never done anything except with FOSS tools: C, Ruby(straight and RoR), Perl, MySQL, et c. I'm thinking that I could probably pick up VB without much trouble (I took a class that used it on college, was impressed at how easy it was to construct Windows UIs, but I've never needed it) Is there any way that I can demonstrate that my experience is similar? What would equivalent experience be in the FOSS world?

• How do I overcome paralysis by analysis when coding?

  - by LuxuryMode

  When I start a new project, I often times immediately start thinking about the details of implementation. "Where am I gonna put the DataBaseHandler? How should I use it? Should classes that want to use it extend from some Abstract superclass..? Should I an interface? What level of abstraction am I going to use in my class that contains methods for sending requests and parsing data?" I end up stalling for a long time because I want to code for extensibility and reusability. But I feel it almost impossible to get past thinking about how to implement perfectly. And then, if I try to just say "screw it, just get it done!", I hit a brick wall pretty quickly because my code isn't organized, I mixed levels of abstractions, etc. What are some techniques/methods you have for launching into a new project while also setting up a logical/modular structure that will scale well?

• How to include serious personal project in Resume?

  - by mob1lejunkie

  My brother has come up with an interesting business idea that could be commercialised. For over a month I have been creating the foundation for SaaS. I have been treating this as commercial project so designing using patterns and best practices. One of the reasons I want to include this in my Resume is my full time job doesn't involve current trendy ASP.Net technologies (e.g Linq/Entity Relationships, jQuery, ASP.Net MVC 3, Silverlight, etc) so the resume lacks impact. In my full time job I work on a 7 year old well designed product and since our data and web layers work well it would be stupid to re-engineer them only because recruiters think Linq, ASP.Net MVC and jQuery are cool. How can I include my personal project in Resume so that it doesn't sound like experiment or quick'n'dirty pet project? Many thanks.

• How to explain pointers to a Java/VB programmer

  - by Skeith

  I am writing a game and my friend has offered to help me as it is a RPG and will take a long time to do the "scripting" bit of the game. The problem is IMO he's not that good a programmer :( (add flame war here). He has only programmed in Java and VB and keeps saying really stupid things to me like "Why don't you drag and drop an onClick event" to design my UI when I'm using DirectX. I tried explaining pointers to him but his response was, if it's just a variable that holds a memory address, why don't you just use an int? I create an instance of an attack class and give the creature a pointer to it so if several creatures use the same attack there is only one instance of it. He keeps saying why not put if statements in the creature class for every attack class and set true for the ones that are there. He has programmed mainly in VB and a little in Java just to learn OOP. How can I explain advanced C++ concepts like pointers and memory management to him? He just doesn't understand there are no super functions like form.show in C++.

• What should be the minimal design/scope documentation before development begins?

  - by Oliver Hyde

  I am a junior developer working on my own in the programming aspect of projects. I am given a png file with 5-6 of the pages designed, most times in specific detail. From this I'm asked to develop the back end system needed to maintain the website, usually a cataloging system with products, tags and categories and match the front end to the design. I find myself in a pickle because when I make decisions based on assumptions about the flow of the website, due to a lack of outlining details, I get corrected and am required to rewrite the code to suit what was actually desired. This process happens multiple times throughout a project, often times on the same detail, until it's finally finished, with broken windows all through it. I understand that projects have scope creep, and can appreciate that I need to plan for this, but I feel that in this situation, I'm not receiving enough outlining details to effectively plan for the project, resulting in broken code and a stressed mind. What should be the minimal design/scope documentation I receive before I begin development?

• What is the best policy for allowing clients to change email?

  - by Steve Konves

  We are developing a web application with a fairly standard registration process which requires a client/user to verify their email address before they are allowed to use the site. The site also allows users to change their email address after verification (with a re-type email field, as well). What are the pros and cons of having the user re-verify their email. Is this even needed? EDIT: Summary of answers and comments below: "Over-verification annoys people, so don't use it unless critical Use a "re-type email" field to prevent typos Beware of overwriting known good data with potentially good data Send email to old for notification; to new for verification Don't assume that the user still has access to the old email Identify impact of incorrect email if account is compromised

• Perl: Negative look behind regex question [migrated]

  - by James

  The Perlre in Perldoc didn't go into much detail on negative look around but I tried testing it, and didn't work as expected. I want to see if I can differentiate a C preprocessor macro definition (e.g. #define MAX(X) ....) from actual usage (y = MAX(x);), but it didn't work as expected. my $macroName = 'MAX'; my $macroCall = "y = MAX(X);"; my $macroDef = "# define MAX(X)"; my $boundary = qr{\b$macroName\b}; my $bstr = " MAX(X)"; if($bstr =~ /$boundary/) { print "boundary: $bstr matches: $boundary\n"; } else { print "Error: no match: boundary: $bstr, $boundary\n"; } my $negLookBehind = qr{(?<!define)\b$macroName\b}; if($macroCall =~ /$negLookBehind/) # "y = MAX(X)" matches "(?<!define)\bMAX\b" { print "negative look behind: $macroCall matches: $negLookBehind\n"; } else { print "no match: negative look behind: $macroCall, $negLookBehind\n"; } if($macroDef =~ /$negLookBehind/) # "#define MAX(X)" should not match "(?<!define)\bMAX\b" { print "Error: negative look behind: $macroDef matches: $negLookBehind\n"; } else { print "no match: negative look behind: $macroDef, $negLookBehind\n"; } It seems that both $macroDef and $macroCall seem to match regex /(?<!define)\b$macroName\b/. I backed off from the original /(?<\#)\s*(?<!define)\b$macroName\b/ since that didn't work either. So what did I screw up? Also does Perl allow chaining of multiple look around expressions?

• UML Class Diagram: Abstract or Interface?

  - by J Smith

  I am modeling a class diagram and have spotted an opportunity to simplify it slightly. What I want to know is, would this it be better to implement an abstract class or an interface? The scenario is this, I have the classes: Artist Genre Album Song All of which share the methods getName, setName, and getCount (playcount that is). Would it be best to create an abstract 'Music' class with the aforementioned abstract methods, or should I create an interface, since the classes that implement the interface have to include all of the interface's methods (I think, correct me if I'm wrong). I hope I've given enough detail, please ask questions if I haven't. Thanks!

• Backbone.js, Rails and code duplication

  - by Matteo Pagliazzi

  I'm building a web app and I need a JS framework like Backbone.js to work with my backend rovided by Rails that mostly return JSON objects after DB queries. Searching on the web I've discovered Backbone which seems to be complete, quite populare and actively developed but I've noticed that a lot of things done by Backbone are simply a duplicte of the works done by Rails: for example validation and models. My idea of "perfect" (for my actual needs) JS mvc (it can't be called mvc but i don't have any other names) is something really simple that has a function for each action in my Rails controller that are triggered by a specific event (user/hash changes, click on a button...) and send requests to the server that respond with a JSON object then I'll load a template or execute some JS code. Do you have any concern/suggestion about my idea? Do you know some "micro" js framework like what i have described? If you have worked with backone.js + rails what can you suggest me?

• Versioning millions of files with distributed SCM

  - by C. Lawrence Wenham

  I'm looking into the feasibility of using off-the-shelf distributed SCMs such as Git or Mercurial to manage millions of XML files. Each file would be a commercial transaction, such as a purchase order, that would be updated perhaps 10 times during the lifecycle of the transaction until it is "done" and changes no more. And by "manage", I mean that the SCM would be used to not just version the files, but also to replicate them to other machines for redundancy and transfer of IP. Lets suppose, for the sake of example, that a goal is to provide good performance if it was handling the volume of orders that Amazon.com claimed to have at its peak in December 2010: about 150,000 orders per minute. We're expecting the system to be distributed over many servers in order to get reasonable performance. We're also planning to use solid-state drives exclusively. There is a reason why we don't want to use an RDBMS for primary storage, but it's a bit beyond the scope of this question. Does anyone have first-hand experience with the performance of distributed SCMs under such a load, and what strategies were used? Open-source preferred, since the final product is to be FOSS, too.

• What is the correlation between the quality of the software development process and the quality of the product?

  - by Ophir Yoktan

  I used to believe the practicing "good" software development methods tends to yield a better product in the long run. However, I've seen quite a few cases where "quick-and-dirty" \ "brute-force" \ "copy-paste" programming appeared to give decent results quicker, and cheaper. This appears especially in cases where time to market is more critical then maintenance overhead. Is there a correlation between the quality of the development process and techniques and the quality of the product?

• DAO/Webservice Consumption in Web Application

  - by Gavin

  I am currently working on converting a "legacy" web-based (Coldfusion) application from single data source (MSSQL database) to multi-tier OOP. In my current system there is a read/write database with all the usual stuff and additional "read-only" databases that are exported daily/hourly from an Enterprise Resource Planning (ERP) system by SSIS jobs with business product/item and manufacturing/SCM planning data. The reason I have the opportunity and need to convert to multi-tier OOP is a newer more modern ERP system is being implemented business wide that will be a complete replacement. This newer ERP system offers several interfaces for third party applications like mine, from direct SQL access to either a dotNet web-service or a SOAP-like web-service. I have found several suitable frameworks I would be happy to use (Coldspring, FW/1) but I am not sure what design patterns apply to my data access object/component and how to manage the connection/session tokens, with this background, my question has the following three parts: Firstly I have concerns with moving from the relative safety of a SSIS job that protects me from downtime and speed of the ERP system to directly connecting with one of the web services which I note seem significantly slower than I expected (simple/small requests often take up to a whole second). Are there any design patterns I can investigate/use to cache/protect my data tier? It is my understanding data access objects (the component that connects directly with the web services and convert them into the data types I can then work with in my Domain Objects) should be singletons (and will act as an Adapter/Facade), am I correct? As part of the data access object I have to setup a connection by username/password (I could set up multiple users and/or connect multiple times with this) which responds with a session token that needs to be provided on every subsequent request. Do I do this once and share it across the whole application, do I setup a new "connection" for every user of my application and keep the token in their session scope (might quickly hit licensing limits), do I set the "connection" up per page request, or is there a design pattern I am missing that can manage multiple "connections" where a requests/access uses the first free "connection"? It is worth noting if the ERP system dies I will need to reset/invalidate all the connections and start from scratch, and depending on which web-service I use might need manually close the "connection/session"

• Rails and Mongoid best way to implement sharing system

  - by Matteo Pagliazzi

  I have to model User and Board in rails using mongoid as ODM. Each board is referenced to an user through a foreign key user_id and now I want to add the ability to share a board with other users. Following CRUD I'd create a new Model called something like Share and it's releated Controller with the ability to create/edit/delete a Share but I have some doubts: First, where to save informations about Shares? I think I may create a field in the Board's collection called shared_with including an array of user ids. in a MySQL I'd created a new table with the ids of who share, the resource shared and the user the resources is shared with but I don't think that's necessary using MongoDB. Every user a Board is shared with should be able to edit the Board (but not to delete it) so the Board should have two relations one with the owner and another with the users the board is shared with, right? For permission (the owner should be able to delete a board but the users it is shared with shouldn't) what to use? I'm using Devise for authentication but I think something like CanCan would fit better. but how to implement it? What do you think about this way? Do you find any problems or have better solutions?

• Detect frameworks and/or CMS utilized on websites in Firefox

  - by jkneip

  I'm redesigning the website for my academic library and am examining other sites to determine to identify the technologies used. Things like: Web frameworks Javascript frameworks Server-side technology Content management system Now I've had some real success in Firefox using plugins like Wappalyzer, Firebug, and the DOM Inspector. But some sites just don't display any of the info. I'm looking for using these tools, especially it seems it an enterprise-level CMS is being used. Does anyone know of any other tools to detect this kind of data? Also with Firebug & the DOM Inspector, there is a lot of info. displayed and I wondered if there was a way to derive the presence of server-side technologies, CMS's, etc. within certain elements of a web page? Also, if this question is more relevant to another Stack Exchange site, please let me know and I'll post it there instead. Much thanks, Jason

• Is the development of CLI apps considered "backward"?

  - by user61852

  I am a DBA fledgling with a lot of experience in programming. I have developed several CLI, non interactive apps that solve some daily repetitive tasks or eliminate the human error from more complex albeit not so daily tasks. These tools are now part of our tool box. I find CLI apps are great because you can include them in an automated workflow. Also the Unix philosophy of doing a single thing but doing it well, and letting the output of a process be the input of another, is a great way of building a set of tools than would consolidate into an strategic advantage. My boss recently commented that developing CLI tools is "backward", or constitutes a "regression". I told him I disagreed, because most CLI tools that exist now are not legacy but are live projects with improved versions being released all the time. Is this kind of development considered "backwards" in the market? Does it look bad on a rèsumè? I also considered all solutions whether they are web or desktop, should have command line, non-interactive options. Some people consider this a waste of programming resources. Is this goal a worthy one in a software project?

• Is it appropriate for a class to only be a collection of information with no logic?

  - by qegal

  Say I have a class Person that has instance variables age, weight, and height, and another class Fruit that has instance variables sugarContent and texture. The Person class has no methods save setters and getters, while the Fruit class has both setters and getters and logic methods like calculateSweetness. Is the Fruit class the type of class that is better practice than the Person class. What I mean by this is that the Person class seems like it doesn't have much purpose; it exists solely to organize data, while the Fruit class organizes data and actually contains methods for logic.

• Link between tests and user stories

  - by Sardathrion

  I have not see these links explicitly stated in the Agile literature I have read. So, I was wondering if this approach was correct: Let a story be defined as "In order to [RESULT], [ROLE] needs to [ACTION]" then RESULT generates system tests. ROLE generates acceptance tests. ACTION generates component and unit tests. Where the definitions are the ones used in xUnit Patterns which to be fair are fairly standard. Is this a correct interpretation or did I misunderstand something?
