• Tools for managing eCommerce backend

  - by rboarman

  I am working with an eCommerce company that has outgrown their hacked together backend for managing inventory, pricing and feeds to various shopping engines (Yahoo, 3d cart, Amazon, etc.). They currently manage about 12,000 skus and are doing $40M in revenue. Their internal people are working on a new Magento solution, but that is six months away and they need to replace/improve their current solution in order to hold them over. Their current solution was developed by two people who have left the company. What tools/architecture do other eCommerce sites use to manage their inventory, pricing, product descriptions and feed generation for the shopping engines? The current solution looks like this: 1) Inventory, pricing and product descriptions are maintained in a database and in NetSuite by employees 2) New products are added to the database via import 3) Twice a week data is extracted into a giant Excel spreadsheet 4) The Excel file adjusts pricing based on some simple algorithms 5) The Excel file exports about six different csv feeds which are manually uploaded to Amazon, 3d cart, Yahoo, Google and Merchant Advantage a. Each feed is a variant of the product which different field names and formatting b. Pricing levels differ between feeds c. Some products are not sent to all feeds 6) Orders are manually parsed and the inventory is adjusted as needed once product is sold The new solution should: 1) Import data from ODBC, CSV and NetSuite (CSV via ftp) 2) Apply pricing changes via simple algorithms (< $80 add $10, $200 add $25) 3) Ensure margins are being met 4) Format and generate a bunch of CSV and XML feeds 5) Perhaps upload feeds to shopping engines automatically What I need to do is replace the Excel file with something that is maintainable and automated. Something in the .Net stack is preferable but not mandatory. I’ve been looking at BizTalk but it may take too long to develop and deploy. Any suggestions?

• Site Web Analytics not updating Sharepoint 2010

  - by Rohit Gupta

  If you facing the issue that the web Analytics Reports in SharePoint 2010 Central Administration is not updating data. When you go to your site > site settings > Site Web Analytics reports or Site Collection Analytics reports  You get old data as in the ribbon displayed "Data Last Updated: 12/13/2010 2:00:20 AM" Please insure that the following things are covered: Insure that Usage and Data Health Data Collection service is configured correctly. Log Collection Schedule is configured correctly Microsoft Sharepoint Foundation Usage Data Import and Microsoft SharePoint Foundation Usage Data Processing Timer jobs are configured to run at regular intervals One last important Timer job is the Web Analytics Trigger Workflows Timer Job insure that this timer job is enabled and scheduled to run at regular intervals (for each site that you need analytics for). After you have insured that the web analytics service configuration is working fine and the Usage Data Import job is importing the *.usage files from the ULS LOGS folder into the WSS_Logging database, and that all the required timer jobs are running as expected… wait for a day for the report to get updated… the report gets updated automatically at 2:00 am in the morning… and i could not find a way to control the schedule for this report update job. So be sure to wait for a day before giving up :)

• Importing tab delimited file into array in Visual Basic 2013 [migrated]

  - by JaceG

  I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub

• What's cool about Lisp nowadays? [closed]

  - by Kos

  Possible Duplicates: Why is Lisp useful? Is LISP still useful in today's world? Which version is most used? First of all, let me clarify: I'm aware of Lisp's place in history, as well as in education. I'm asking about its place in practical application, as of 2011. The question is: What features of Lisp make it the preferred choice for projects today? It's widely used in various AI areas as far as I know, and probably also elsewhere. I can imagine projects choosing, for instance... Python because of its concise, readable syntax and it being dynamic, Haskell for being pure functional with a powerful type system, Matlab/Octave for the focus on numerics and big standard libraries, Etc. When should I consider Lisp the proper language for a given problem? What language features make it the preferred choice then? Is its "purity and generality" an advantage which makes it a better choice for some subset of projects than the modern languages? edit- On your demand, a little rephrase (or simply a tl;dr) to make this more specific: a) What problems are solvable with Lisp much more easily than with more common, modern languages like Python or C# (or even F# or Scala)? b) What language features specific for Lisp make it the best choice for those problems?

• accessing live usb files from new hd ubuntu install

  - by Robin Bailey

  After my live USB (ubuntu 12.04 lts) refused to boot, I proceeded to install the same Ubuntu version on the laptop hard drive (a dual boot next to Win xp). This all went well without a hitch. Previous to this, I spent several weeks enjoying and exploring ubuntu from the usb pendrive. During this time I changed lots of settings and customized Firefox and more. Now, I'd like to import the home folder from the usb drive into the new install home folder on the hard disk, which is the purported folder that holds all those special settings to my knowledge. Unfortunately and only being familiar with Windows file systems, the view of the usb file system from the new hdd install is totally perplexing. I can't find anything that looks anywhere close to the original file system. More, I can't find any of the files I had created and stored there, like the LibreOfficeCalc file that has all my passwords (this one is really discouraging) that was stored on the ubuntu desktop. Help me find this file alone and I'll bow down with full apologies to any and all computer gods. Being able to import all those customizing settings into the new install would be a major bonus also, but hey, I'm not greedy. I'll take the passwords file and be happy! And humble! I would be very grateful for some clear, understandable help on this. Thanks

• How do I get my programs to communicate with each other

  - by Benjamin Lindqvist

  I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

• Using runtime generic type reflection to build a smarter DAO

  - by kerry

  Have you ever wished you could get the runtime type of your generic class? I wonder why they didn’t put this in the language. It is possible, however, with reflection: Consider a data access object (DAO) (note: I had to use brackets b/c the arrows were messing with wordpress): public interface Identifiable { public Long getId(); } public interface Dao { public T findById(Long id); public void save(T obj); public void delete(T obj); } Using reflection, we can create a DAO implementation base class, HibernateDao, that will work for any object: import java.lang.reflect.Field; import java.lang.reflect.ParameterizedType; public class HibernateDao implements Dao { private final Class clazz; public HibernateDao(Session session) { // the magic ParameterizedType parameterizedType = (ParameterizedType) clazz.getGenericSuperclass(); return (Class) parameterizedType.getActualTypeArguments()[0]; } public T findById(Long id) { return session.get(clazz, id); } public void save(T obj) { session.saveOrUpdate(obj); } public void delete(T obj) { session.delete(obj); } } Then, all we have to do is extend from the class: public class BookDaoHibernateImpl extends HibernateDao { }

• What technology or skillset should I learn today in order to be able to charge $250+ / hr in 2-3 years? [closed]

  - by Ryan Waggoner

  I've been doing PHP freelance development for the last 4-5 years and I'm starting to max out my hourly rate. So in 2010 I decided to transition to a new language. I played with Python and Ruby, but ended up settling on iOS, for three reasons: I'm enjoying the challenge of working on a completely different type of development, instead of another flavor of web development The demand seems higher right now than for Ruby or Python I see iOS developers charging $150 - 250 / hr Whether these reasons are right or wrong, I've been learning iOS for the last year and I'm starting to get more work in that field. I feel confident that in six months (barring any major shifts in the ecosystem), I can be billing iOS work at $150 / hr or more. However, I'm feeling that I should have done this earlier, that I've missed the boat, and that iOS development is going to dry up or get much more commoditized. Whether this is true or not isn't really my question (though feel free to comment). What I want to know is: what should I start learning right now so that I can be ahead of the curve in a couple years when the demand is far outstripping supply? What technologies or skillsets are going to be so heavily in demand in 2-3 years that you'll be able to charge $250 / hr or more and stay busy? These don't have to be new technologies either...the answer could be iOS or COBOL or whatever.

• CoffeeScript - inability to support progressive adoption

  - by Renso

  First if, what is CoffeeScript?Web definitionsCoffeeScript is a programming language that compiles statement-by-statement to JavaScript. The language adds syntactic sugar inspired by Ruby and Python to enhance JavaScript's brevity and readability, as well as adding more sophisticated features like array comprehension and pattern matching.The issue with CoffeeScript is that it eliminates any progressive adoption. It is a purist approach, kind of like the Amish, if you're not borne Amish, tough luck. So for folks with thousands of lines of JavaScript code will have a tough time to convert it to CoffeeScript. You can use the js2coffee API to convert the JavaScript file to CoffeeScript but in my experience that had trouble converting the files. It would convert the file to CoffeeScript without any complaints, but then when trying to generate the CoffeeScript file got errors with guess what: INDENTATION!Tried to convince the CoffeeScript community on github but got lots of push-back to progressive adoption with comments like "stupid", "crap", "child's comportment", "it's like Ruby, Python", "legacy code" etc. As a matter of interest one of the first comments were that the code needs to be re-designed before converted to CoffeeScript. Well I rest my case then :-)So far the community on github has been very reluctant to even consider introducing some way to define code-blocks, obviously curly braces is not an option as they use it for json object definitions. They also have no consideration for a progressive adoption where some, if not all, JavaScript syntax will be allowed which means all of us in the real world that have thousands of lines of JavaScript will have a real issue converting it over. Worst, I for one lack the confidence that tools like js2coffee will provide the correct indentation that will determine the flow of control in your code!!! Actually it is hard for me to find enough justification for using spaces or tabs to control the flow of code. It is no wonder that C#, C, C++, Java, all enterprise-scale frameworks still use curly braces. Have never seen an enterprise app built with Ruby or PhP.Let me know what your concerns are with CoffeeScript and how you dealt with large scale JavaScript conversions to CoffeeScript.

• Why do I have an error when adding states in slick?

  - by SystemNetworks

  When I was going to create another state I had an error. This is my code: public static final int play2 = 3; and public Game(String gamename){ this.addState(new mission(play2)); } and public void initStatesList(GameContainer gc) throws SlickException{ this.getState(play2).init(gc, this); } I have an error in the addState. above the above code. I don't know where is the problem. But if you want the whole code it is here: package javagame; import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class Game extends StateBasedGame{ public static final String gamename = "NET FRONT"; public static final int menu = 0; public static final int play = 1; public static final int train = 2; public static final int play2 = 3; public Game(String gamename){ super(gamename); this.addState(new Menu(menu)); this.addState(new Play(play)); this.addState(new train(train)); this.addState(new mission(play2)); } public void initStatesList(GameContainer gc) throws SlickException{ this.getState(menu).init(gc, this); this.getState(play).init(gc, this); this.getState(train).init(gc, this); this.enterState(menu); this.getState(play2).init(gc, this); } public static void main(String[] args) { try{ AppGameContainer app =new AppGameContainer(new Game(gamename)); app.setDisplayMode(1500, 1000, false); app.start(); }catch(SlickException e){ e.printStackTrace(); } } } //SYSTEM NETWORKS(C) 2012 NET FRONT

• Best practices in versioning

  - by Gerenuk

  I develop some scripts for data analysis in a small team. For the moment we use SVN, but not in a very structured way. We haven't even looked how to use branches even though we need this functionality. What do you suggest as the best practice to setup the following system: two code bases (core and plugins) versions can be incompatible to previous scripts sometimes individual features are being developed and not yet finished, while other fixes have to be done urgently to the code In the end we don't deliver the code as a package, but rather place the Python scripts in some directory (with version names?). Some other python script which serves as a configuration choses the desired version, sets the path to these libraries and then starts to import the modules. I saw stable releases to be named "trunk" so I did the same. However, no version numbers yet. Core and plugins are different repositories, however we have to match versions for compatibility. Can you suggest some best practices or reference to ease development and reduce chaos? :) Some suggested GIT. I haven't heard about it, but I'm free to change.

• What's so great about Clojure?

  - by marco-fiset

  I've been taking a look at Clojure lately and I stumbled upon this post on Stackoverflow that indicates some projects following best practices, and overall good Clojure code. I wanted to get my head around the language after reading some basic tutorials so I took a look at some "real-world" projects. After looking at ClojureScript and Compojure (two the the aforementioned "good" projects), I just feel like Clojure is a joke. I don't understand why someone would pick Clojure over say, Ruby or Python, two languages that I love and have such a clean syntax and are very easy to pick up whereas Clojure uses so much parenthesis and symbols everywhere that it ruins the readability for me. I think that Ruby and Python are beautiful, readable and elegant. They are easy to read even for someone who does not know the language inside out. However, Clojure is opaque to me and I feel like I must know every tiny detail about the language implementation in order to be able to understand any code. So please, enlighten me! What is so good about Clojure? What is the absolute minimum that I should know about the language in order to appreciate it?

• Save Actions in NetBeans IDE 7.3

  - by Geertjan

  Several developers, especially those familiar with equivalent functionality in Eclipse, have been asking for so-called "Save Actions", that is, support for actions that are automatically performed when a file is saved. Here's the related NetBeans issue: http://netbeans.org/bugzilla/show_bug.cgi?id=140719   In NetBeans IDE 7.3, the issue is resolved as follows: A new "On Save" tab is found in the "Editor" tab of the Options window. Defaults for all languages are set via the "All Languages" item in the drop-down. Here, for all languages, you can specify what kind (all, none, or only modified lines) of formatting and space removal will occur automatically when a file is saved: Via the drop-down, you see all the languages supported by the IDE: You can pick a language and then override the default On Save settings: Per language, there may be additional On Save settings. For example, for Java, you can specify that, when saving a Java file, unused import statements should be removed and/or the rules you've set for organizing import statements should be applied: There's also a set of new NetBeans IDE APIs for adding new On Save functionality via custom plugins. Via MIME type registration of OnSaveTask.Factory, you can register new On Save actions that will be run for files conforming to the relevant MIME type. There's also extensions via the Editor Options API for registering new panels (one per language) to the On Save panel in the Options window. I'll demonstrate some examples of the APIs in upcoming blog entries.

• Time Zone on WebLogic Server

  - by adejuanc

  In order to configure the time zone with WebLogic Server, use the following JVM startup command: -Duser.timezone=<timezone> For example, in the java arguments in the admin console at Environments -> Servers -> Servername -> - Server Start tab, configure the startup settings that Node Manager will use to start the particular server. For example: -Duser.timezone='America/Arizona' There are many different time zones, each with its own code. For a complete list please refer to : http://en.wikipedia.org/wiki/List_of_zoneinfo_time_zones For testing, you can run the following code on WLS with a JSP, servlet, or deploying the class: import java.util.Calendar; import java.util.TimeZone; public class TestTimeZone {  public static void main(String[] args) {    Calendar calendar = Calendar.getInstance();    TimeZone timeZone = calendar.getTimeZone();    System.out.println(" your Current TimeZone is : " + timeZone.getDisplayName());    System.out.println(" Time Zone id : "+ timeZone.getID());  } }

• Are short abbreviated method/function names that don't use full words bad practice or a matter of style?

  - by Alb

  Is there nowadays any case for brevity over clarity with method names? Tonight I came across the Python method repr() which seems like a bad name for a method to me. It's not an English word. It apparently is an abbreviation of 'representation' and even if you can deduce that, it still doesn't tell you what the method does. A good method name is subjective to a certain degree, but I had assumed that modern best practices agreed that names should be at least full words and descriptive enough to reveal enough about the method that you would easily find one when looking for it. Method names made from words help let your code read like English. repr() seems to have no advantages as a name other than being short and IDE auto-complete makes this a non-issue. An additional reason given in an answer is that python names are brief so that you can do many things on one line. Surely the better way is to just extract the many things to their own function, and repeat until lines are not too long. Are these just a hangover from the unix way of doing things? Commands with names like ls, rm, ps and du (if you could call those names) were hard to find and hard to remember. I know that the everyday usage of commands such as these is different than methods in code so the matter of whether those are bad names is a different matter.

• Does it make sense to write build scripts in C++?

  - by Klaim

  I'm using CMake to generate my projects IDE/makefiles, but I still need to call custom "scripts" to manipulate my compiled files or even generate code. In previous projects I've been using Python and it was OK, but now I'm having serious trouble managing a lot of dependencies in two very big projects I'm working on so I want to minimize the dependencies everywhere. Someone suggested to me to use C++ to write my build scripts instead of adding a language dependency just for that. The projects themeselves already use C++ so there are several advantages that I can see: to build the whole project, only a C++ compiler and CMake would be necessary, nothing else (all the other dependencies are C or C++); C++ type safety (when using modern C++) makes everything easier to get "correct"; it's also the language I know the better so I'm more at ease with it even if I'm able to write some good Python code; potential gain in execution speed (but i don't think it will really be perceptible); However, I think there might be some drawbacks and I'm not sure of the real impact as I didn't try yet: might be longer to write the code (that said I'm not sure because I'm efficient enough in C++ to write something that work quickly, so maybe for this system it wouldn't be so long to write) (compilation time shouldn't be a problem for this case); I must assume that all the text files I'll read as input are in UTF-8, I'm not sure it can be easilly checked at runtime in C++ and the language will not check it for you; libraries in C++ are harder to manage than in scripting languages; I lack experience and forsight so maybe I'm missing advantages and drawbacks. So the question is: does it make sense to use C++ for this? do you have experiences to report and do you see advantages and disadvantages that might be important?

• Is white the best base color to start with when planning to shade sprites within Unity?

  - by SpartanDonut

  I'm looking into prototyping a game in Unity which will consist of solid square sprites / tiles. I figure I can represent different types of objects with different colors for each of the tiles in the game. I figure that I can import a single square sprite and shade it appropriately in Unity as opposed to imported squares of many different colors. My experience with adjusting the hue and saturation within Photoshop shows that white is not an easy color to change as things that are white often stay white. My testing in Unity shows that I can change the "color" of a sprite to anything other than white and the sprite is seemingly shaded appropriately, despite what I would have thought given my Photoshop experience. Since white objects do seem to take on the appropriate color shading when changed within Unity my gut tells me that this is the best base color to begin with, meaning that I can import a single white square sprite and simply adjust the color to represent different objects and object states. Is a white sprite actually the best color sprite to begin with and why does something like this work in Unity as opposed to adjusting the hue and saturation within Photoshop?

• Screen going black, further investigation reveals healthy ram and hard disk, and several kernel oops logs

  - by Virulan

  Six days ago, I went to go take a shower, and I suspended Ubuntu as usual, to save battery life. I came back, and the screen was black. REISUB and general fiddling around did nothing. Restarted, and still had nothing on the screen. Since then, this has happened several times, and the only fix is to 1) force shut laptop, 2) take out battery, 3) hold power button, 4) put battery back in, 5) boot. I have investigated further into the matter, doing a ram test and a hard disk check. Both turned out fine, but then my attention turned towards the error messages I was receiving upon bootup, the whole "System program problem detected" dealio. I did some digging and found four kernel oops logs in my /var/crash. What I can understand of them points to two things, 1) they are connected to my suspending problems, since there are four them (I have had four suspending crashes), and they both confirm that there was a issue with waking up from suspend, and 2) the crashes might have to do with Python (possibly could be jumping to conclusions), since mentions of Python are peppered throughout the logs. At this point, I am unsure of how to continue, and I have come here for help. Is there any way I can fix this? Should I start by uploading the logs here?

• 25 years old and considering a career change...possible? practical?

  - by mq330

  Hi all, I'm new to this site and new to programming as well. I've spent some time going through an intro cs book that uses python as the language of choice. I find the exercises interesting and engaging and I generally have had a favorable experience programming so far. I've gone through some of the basics with python like writing simple programs, basics of GUIs, manipulating strings, lists, defining functions, etc. And I've always loved technology. Although I've never done any real hardcore programming yet, I was inclined to building websites from a very young age but I never really developed my skills. Now, the thing is I'm 25, I have my bacholors in environmental studies and two masters degrees in urban planning and landscape architecture respectively. I know, it would be quite a departure to pursue a career in programming at this point. Currently, I'm working as a geographic information systems intern. I've taken some GIS classes and have a lot of experience with making maps, doing spatial analysis etc. So what I'm thinking is maybe I can learn some solid programming skills and apply these skills in the field of GIS. From what I've seen, .net languages are the norm in this arena. Could you perhaps provide some guidance to me in terms of what languages I should focus on or courses I should take at this point? What about for building web mapping applications? Also, I was thinking about getting a certificate in programming from a university extension program. Do you think it would be worth it? And furthermore, do you think potential employers would be interested in hiring someone like me (once I get a couple of languages down pretty well) as an intern or in an entry level position? I'll be living in the bay area so I feel that there should be decent opportunities even though I don't have a b.s. in cs.

• The better way to ask for input?

  - by Skippy

  I am wondering which is the best way to go with java code. I need to create a class with simple prompts for input.. I have tried using both classes and cannot work out the particular benefits for each. Is this because I am still in the early stages of programming or are there situations that will occur as it becomes more complex?? import java.util.Scanner; public class myClass { Scanner stdin = new Scanner(System.in); public String getInput(String prompt) { System.out.print(prompt); return stdin.nextLine(); } ... or import java.io.*; public class myClass { public static void main(String[] args) throws IOException { BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in)); System.out.print("Input something: "); String name = stdin.readLine(); I know these examples are showing different methods within these classes, but thought this might serve well for the discussion. I'm really not sure which site is the best to ask this on.

• Space Invaders-type game: Keeping the enemies aligned with each other as they turn around?

  - by CorundumGames

  OK, so here's the lowdown of the problem I'm trying to solve. I'm developing a game in PyGame that's a cross between Space Invaders and Columns. I'm trying to make the motion of the enemies similar to that of the aliens in Space Invaders; that is, they're all clustered in a grid, and if even one hits the side of the screen, the entire formation moves down and turns around. However, the motion of these aliens is continuous (as continuous as a monitor can be, anyway), not on a discrete grid like in the original. The enemies are instances of an Enemy class, and in turn they're held by a 2D array in a enemysquadron module (which, if you don't use Python, is in this case essentially a singleton due to the way Python modules work). Inside the Enemy class I have a class-scope velocity vector that is reversed every time an Enemy object touches the edge of the screen. This won't do, though, because as time goes on the enemies just become disorganized and jumbled (i.e. not in a grid as planned). I haven't implemented the Enemies going downward yet, so let's not worry about that right now. Any tips?

• Learning how to design knowledge and data flow [closed]

  - by max

  In designing software, I spend a lot of time deciding how the knowledge (algorithms / business logic) and data should be allocated between different entities; that is, which object should know what. I am asking for advice about books, articles, presentations, classes, or other resources that would help me learn how to do it better. I code primarily in Python, but my question is not really language-specific; even if some of the insights I learn don't work in Python, that's fine. I'll give a couple examples to clarify what I mean. Example 1 I want to perform some computation. As a user, I will need to provide parameters to do the computation. I can have all those parameters sent to the "main" object, which then uses them to create other objects as needed. Or I can create one "main" object, as well as several additional objects; the additional objects would then be sent to the "main" object as parameters. What factors should I consider to make this choice? Example 2 Let's say I have a few objects of type A that can perform a certain computation. The main computation often involves using an object of type B that performs some interim computation. I can either "teach" A instances what exact parameters to pass to B instances (i.e., make B "dumb"); or I can "teach" B instances to figure out what needs to be done when looking at an A instance (i.e., make B "smart"). What should I think about when I'm making this choice?
