• Beyond Syntax Highlighting - What other code representations are possible today?

  - by Mathieu Hélie

  Despite GUI applications having been around for 30ish years, software is still written as lines of text instructions, for various valid reasons. But we've also found that manipulating these text instructions is mind-blowingly difficult unless we apply a layer of coloring on different words to represent their syntax, thus allowing us to quickly parse through these text files without having to read the whole words. But besides the Sublime Text minimap feature, I've yet to see any innovation in visual representation of code since colors came around on CRT monitors. I can think of one obviously essential representation that modern graphics technology allows: visual hierarchies for nested structures. If we make nested text slightly smaller than its outer context, and zoom on it when the cursor is focused on the line, then we will be able to browse huge files of nested statements very quickly. This becomes even more essential as languages based on closures and anonymous functions become filled with deep statements. Has anyone attempted to implement this in a text editor? Do you know of any otherwise useful improvements in representing code text graphically?

• Array Multiplication and Division

  - by Narfanator

  I came across a question that (eventually) landed me wondering about array arithmetic. I'm thinking specifically in Ruby, but I think the concepts are language independent. So, addition and subtraction are defined, in Ruby, as such: [1,6,8,3,6] + [5,6,7] == [1,6,8,3,6,5,6,7] # All the elements of the first, then all the elements of the second [1,6,8,3,6] - [5,6,7] == [1,8,3] # From the first, remove anything found in the second and array * scalar is defined: [1,2,3] * 2 == [1,2,3,1,2,3] But What, conceptually, should the following be? None of these are (as far as I can find) defined: Array x Array: [1,2,3] * [1,2,3] #=> ? Array / Scalar: [1,2,3,4,5] / 2 #=> ? Array / Scalar: [1,2,3,4,5] % 2 #=> ? Array / Array: [1,2,3,4,5] / [1,2] #=> ? Array / Array: [1,2,3,4,5] % [1,2] #=> ? I've found some mathematical descriptions of these operations for set theory, but I couldn't really follow them, and sets don't have duplicates (arrays do). Edit: Note, I do not mean vector (matrix) arithmetic, which is completely defined. Edit2: If this is the wrong stack exchange, tell me which is the right one and I'll move it. Edit 3: Add mod operators to the list. Edit 4: I figure array / scalar is derivable from array * scalar: a * b = c => a = b / c [1,2,3] * 3 = [1,2,3]+[1,2,3]+[1,2,3] = [1,2,3,1,2,3,1,2,3] => [1,2,3] = [1,2,3,1,2,3,1,2,3] / 3 Which, given that programmer's division ignore the remained and has modulus: [1,2,3,4,5] / 2 = [[1,2], [3,4]] [1,2,3,4,5] % 2 = [5] Except that these are pretty clearly non-reversible operations (not that modulus ever is), which is non-ideal. Edit: I asked a question over on Math that led me to Multisets. I think maybe extensible arrays are "multisets", but I'm not sure yet.

• Can You Have "Empty" Abstract/Classes?

  - by ShrimpCrackers

  Of course you can, I'm just wondering if it's rational to design in such a way. I'm making a breakout clone and was doing some class design. I wanted to use inheritance, even though I don't have to, to apply what I've learned in C++. I was thinking about class design and came up with something like this: GameObject - base class (consists of data members like x and y offsets, and a vector of SDL_Surface* MovableObject : GameObject - abstract class + derived class of GameObject (one method void move() = 0; ) NonMovableObject : GameObject - empty class...no methods or data members other than constructor and destructor(at least for now?). Later I was planning to derive a class from NonMovableObject, like Tileset : NonMovableObject. I was just wondering if "empty" abstract classes or just empty classes are often used...I notice that the way I'm doing this, I'm just creating the class NonMovableObject just for sake of categorization. I know I'm overthinking things just to make a breakout clone, but my focus is less on the game and more on using inheritance and designing some sort of game framework.

• Should I choose Doctrine 2 or Propel 1.5/1.6, and why?

  - by Billy ONeal

  I'd like to hear from those who have used Doctrine 2 (or later) and Propel 1.5 (or later). Most comparisons between these two object relational mappers are based on old versions -- Doctrine 1 versus Propel 1.3/1.4, and both ORMs went through significant redesigns in their recent revisions. For example, most of the criticism of Propel seems to center around the "ModelName Peer" classes, which are deprecated in 1.5 in any case. Here's what I've accumulated so far (And I've tried to make this list as balanced as possible...): Propel Pros Extremely IDE friendly, because actual code is generated, instead of relying on PHP magic methods. This means IDE features like code completion are actually helpful. Fast (In terms of database usage -- no runtime introspection is done on the database) Clean migration between schema versions (at least in the 1.6 beta) Can generate PHP 5.3 models (i.e. namespaces) Easy to chain a lot of things into a single database query with things like useXxx methods. (See the "code completion" video above) Cons Requires an extra build step, namely building the model classes. Generated code needs rebuilt whenever Propel version is changed, a setting is changed, or the schema changes. This might be unintuitive to some and custom methods applied to the model are lost. (I think?) Some useful features (i.e. version behavior, schema migrations) are in beta status. Doctrine Pros More popular Doctrine Query Language can express potentially more complicated relationships between data than easily possible with Propel's ActiveRecord strategy. Easier to add reusable behaviors when compared with Propel. DocBlock based commenting for building the schema is embedded in the actual PHP instead of a separate XML file. Uses PHP 5.3 Namespaces everywhere Cons Requires learning an entirely new programming language (Doctrine Query Language) Implemented in terms of "magic methods" in several places, making IDE autocomplete worthless. Requires database introspection and thus is slightly slower than Propel by default; caching can remove this but the caching adds considerable complexity. Fewer behaviors are included in the core codebase. Several features Propel provides out of the box (such as Nested Set) are available only through extensions. Freakin' HUGE :) This I have gleaned though only through reading the documentation available for both tools -- I've not actually built anything yet. I'd like to hear from those who have used both tools though, to share their experience on pros/cons of each library, and what their recommendation is at this point :)

• Student wanting to go to a developer conference

  - by Jamie Keeling

  I'm a 21 year old student in my last year of University, and I am looking for information about developer conferences. I live in Derby (United Kingdom) and there's not (As far as I know) many conferences local to where I live. I do have a car at my disposal so travelling shouldn't be a problem. I was hoping somebody could recommend the best way to go about finding and attending a conference, which one is probably the best to go to and what kind of things I'd need to know and take beforehand. I've done a couple of Google searches and searched SO itself but nothing specific to my needs was found. Note: I'm primarily a C# developer using WPF and WinForms but I'm open to pretty much anything.

• Single python file distribution: module or package?

  - by DanielSank

  Suppose I have a useful python function or class (or whatever) called useful_thing which exists in a single file. There are essentialy two ways to organize the source tree. The first way uses a single module: - setup.py - README.rst - ...etc... - foo.py where useful_thing is defined in foo.py. The second strategy is to make a package: - setup.py - README.rst - ...etc... - foo |-module.py |-__init__.py where useful_thing is defined in module.py. In the package case __init__.py would look like this from foo.module import useful_thing so that in both cases you can do from foo import useful_thing. Question: Which way is preferred, and why? EDIT: Since user gnat says this question is poorly formed, I'll add that the official python packaging tutorial does not seem to comment on which of the methods described above is the preferred one. I am explicitly not giving my personal list of pros and cons because I'm interested in whether there is a community preferred method, not generating a discussion of pros/cons :)

• College Courses through distance learning

  - by Matt

  I realize this isn't really a programming question, but didn't really know where to post this in the stackexchange and because I am a computer science major i thought id ask here. This is pretty unique to the programmer community since my degree is about 95% programming. I have 1 semester left, but i work full time. I would like to finish up in December, but to make things easier i like to take online classes whenever I can. So, my question is does anyone know of any colleges that offer distance learning courses for computer science? I have been searching around and found a few potential classes, but not sure yet. I would like to gather some classes and see what i can get approval for. Class I need: Only need one C SC 437 Geometric Algorithms C SC 445 Algorithms C SC 473 Automata Only need one C SC 452 Operating Systems C SC 453 Compilers/Systems Software While i only need of each of the above courses i still need to take two more electives. These also have to be upper 400 level classes. So i can take multiple in each category. Some other classes I can take are: CSC 447 - Green Computing CSC 425 - Computer Networking CSC 460 - Database Design CSC 466 - Computer Security I hoping to take one or two of these courses over the summer. If not, then online over the regular semester would be ok too. Any help in helping find these classes would be awesome. Maybe you went to a college that offered distance learning. Some of these classes may be considered to be graduate courses too. Descriptions are listed below if you need. Thanks! Descriptions Computer Security This is an introductory course covering the fundamentals of computer security. In particular, the course will cover basic concepts of computer security such as threat models and security policies, and will show how these concepts apply to specific areas such as communication security, software security, operating systems security, network security, web security, and hardware-based security. Computer Networking Theory and practice of computer networks, emphasizing the principles underlying the design of network software and the role of the communications system in distributed computing. Topics include routing, flow and congestion control, end-to-end protocols, and multicast. Database Design Functions of a database system. Data modeling and logical database design. Query languages and query optimization. Efficient data storage and access. Database access through standalone and web applications. Green Computing This course covers fundamental principles of energy management faced by designers of hardware, operating systems, and data centers. We will explore basic energy management option in individual components such as CPUs, network interfaces, hard drives, memory. We will further present the energy management policies at the operating system level that consider performance vs. energy saving tradeoffs. Finally we will consider large scale data centers where energy management is done at multiple layers from individual components in the system to shutting down entries subset of machines. We will also discuss energy generation and delivery and well as cooling issues in large data centers. Compilers/Systems Software Basic concepts of compilation and related systems software. Topics include lexical analysis, parsing, semantic analysis, code generation; assemblers, loaders, linkers; debuggers. Operating Systems Concepts of modern operating systems; concurrent processes; process synchronization and communication; resource allocation; kernels; deadlock; memory management; file systems. Algorithms Introduction to the design and analysis of algorithms: basic analysis techniques (asymptotics, sums, recurrences); basic design techniques (divide and conquer, dynamic programming, greedy, amortization); acquiring an algorithm repertoire (sorting, median finding, strong components, spanning trees, shortest paths, maximum flow, string matching); and handling intractability (approximation algorithms, branch and bound). Automata Introduction to models of computation (finite automata, pushdown automata, Turing machines), representations of languages (regular expressions, context-free grammars), and the basic hierarchy of languages (regular, context-free, decidable, and undecidable languages). Geometric Algorithms The study of algorithms for geometric objects, using a computational geometry approach, with an emphasis on applications for graphics, VLSI, GIS, robotics, and sensor networks. Topics may include the representation and overlaying of maps, finding nearest neighbors, solving linear programming problems, and searching geometric databases.

• As a solo programmer, of what use can Gerrit be?

  - by s.d

  Disclaimer: I'm aware of the questions How do I review my own code? and What advantages do continuous integration tools offer on a solo project?. I do feel that this question aims at a different set of answers though, as it is about a specific software, and not about general musings about the use of this or that practice or tech stack. I'm a solo programmer for an Eclipse RCP-based project. To be able to control myself and the quality of my software, I'm in the process of setting up a CSI stack. In this, I follow the Eclipse Common Build Infrastructure guidelines, with the exception that I will use Jenkins rather than Hudson. Sticking to these guidelines will hopefully help me in getting used to the Eclipse way of doing things, and I hope to be able to contribute some code to Eclipse in the future. However, CBI includes Gerrit, a code review software. While I think it's really helpful for teams, and I will employ it as soon as the team grows to at least two developers, I'm wondering how I could use it while I'm still solo. Question: Is there a use case for Gerrit that takes into account solo developers? Notes: I can imagine reviewing code myself after a certain amount of time to gain a little distance to it. This does complicate the workflow though, as code will only be built once it's been passed through code review. This might prove to be a "trap" as I might be tempted to quickly push bad code through Gerrit just to get it built. I'm very interested in hearing how other solo devs have made use of Gerrit.

• Are C++ templates just a kind of glorified macros?

  - by Gulshan

  From different comparisons among C++ templates and C#/Java generics like this one- http://stackoverflow.com/questions/31693/what-are-the-differences-between-generics-in-c-and-java-and-templates-in-c/31929#31929 I have a got a perception that, C++ templates are implemented by some kind of preprocessing, not compiling. In other words, they are just a kind of C macros. Is this right? Then I felt that, if C++ templates are implemented by preprocessing, dynamic linking(.dll) cannot be used. A quick google search also supports this. And lastly, how can we use macros in C to deliver C++ templates like functionalities? Another thing came in my mind about templates similar to some kind of preprocessor that, there can be integers passed as arguments to some templates. And it even supports kind of recursion. But the recursion is not in the assembly/machine code. So, am I wrong calling templates glorified macros? Unlike normal macros, it has some superior abilities. But isn't it a kind of preprocessing?

• How should I store and secure self-signed certificates?

  - by Anthony Mastrean

  I'm fairly certain I shouldn't commit certificates into source control. Even if the repository is private and only authenticated coworkers (for example) have access to it. That would allow for accidental exposure (thumb drives, leaked credentials, whatever). But, how should I store and secure certificates? I don't suppose I should just plop them on the network file server, for some of the same reasons I wouldn't put them into source control, right? Is there some kind of secure certificate store that I can run? Does the Java "keystore" do that generally or is it specific for like weblogic servers or something?

• scalablity of Scala over Java

  - by Marcus

  I read an article that says Scala handles concurrency better than Java. http://www.theserverside.com/feature/Solving-the-Scalability-Paradox-with-Scala-Clojure-and-Groovy ...the scalability limitation is confined specifically to the Java programming language itself, but it is not a limitation of the Java platform as a whole... The scalability issues with Java aren't a new revelation. In fact, plenty of work has been done to address these very issues, with two of the most successful projects being the programming languages named Scala and Clojure... ...Scala is finding ways around the problematic thread and locking paradigm of the Java language... How is this possible? Doesn't Scala use Java's core libraries which brings all the threading and locking issues from Java to Scala?

• Why is Software Engineering not the typical major for future software developers?

  - by FarmBoy

  While most agree that a certain level of Computer Science is essential to being a good programmer, it seems to me that the principles of good software development is even more important, though not as fundamental. Just like mechanical engineers take physics classes, but far more engineering classes, I would expect, now that software is over a half century old, that software development would begin to dominate the undergraduate curriculum. But I don't see much evidence of this. Is there a reason that Software Engineering hasn't taken hold as an academic discipline?

• Intellectual Property for in house development

  - by Kyle Rogers

  My company is a sub contractor on a major government contract. Over the past 5 years we've been developing in house applications to help support our company and streamline our work. Apparently in 2008 our president of the company at that time signed a continuation of services contract with the company we subcontract with on this project. In the contract amendment various things were discussed such as intellectual property and the creation of new and existing tools. The contract states that all the subcontractor's tools/scripts/etc... become the intellectual property of the main contractor holder. Basically all tools that were created in support of the project which we work on are no longer ours exclusively and they have rights to them. My company really doesn't do software development specifically but because of this contract these tools helped tremendously with our daily tasking. Does my company have any sort of recourse or actions to help keep our tools? My team of developers were completely unaware of any of these negotiations and until recently were kept in the dark about the agreements that were made. Do we as developers have any rights to the software? Since our company is not a software development shop, we have created all these tools without any sort of agreements or contracts within the company stating that we give our company full rights to our creations? I was reading an article by Joel Spolsky on this topic and was just wonder if there is any advice out there to help assist us? Thank you Joel Spolsky's Article

• Need clarification concerning Windows Azure

  - by SnOrfus

  I basically need some confirmation and clarification concerning Windows Azure with respect to a Silverlight application using RIA Services. In a normal Silverlight app that uses RIA services you have 2 projects: App App.Web ... where App is the default client-side Silverlight and app.web is the server-side code where your RIA services go. If you create a Windows Azure app and add a WCF Web Services Role, you get: App (Azure project) App.Services (WCF Services project) In App.Services, you add your RIA DomainService(s). You would then add another project to this solution that would be the client-side Silverlight that accesses the RIA Services in the App.Services project. You then can add the entity model to the App.Services or another project that is referenced by App.Services (if that division is required for unit testing etc.) and connect that entity model to either a SQLServer db or a SQLAzure instance. Is this correct? If not, what is the general 'layout' for building an application with the following tiers: UI (Silverlight 4) Services (RIA Services) Entity/Domain (EF 4) Data (SQL Server)

• Starting off with web dev with php

  - by pavan kumar

  I'm currently working with Java / C++. I'm interested in web development and am planning to shift my stream. I heard that PHP is a good platform to start off and also it does not require that much of knowledge in technologies like JSP / Servlets or frameworks like springs / struts / hibernate. I have basic ideas about HTML and Javascript as well. I have gone through previous posts in SO and found out the relevant resources as well: http://net.tutsplus.com/tutorials/php/the-best-way-to-learn-php/ http://www.webhostingtalk.com/archive/index.php/t-1028265.html http://www.killerphp.com/ http://phpforms.net/tutorial/tutorial.html http://www.php5-tutorial.com/ etc. Now, my question is: I heard of PHP frameworks like CodeIgniter, Zend Frameworkd and Yii. Doesn't learning PHP & MySql implicitly makes us aware of these frameworks? Am I making a good choice in stating with PHP? Is it a good idea to shift streams?

• Using ASP.NET C# and Javascript

  - by ctck

  I'm looking for the most efficient / standardized way of passing data between client javascript code and C# code behind in an ASP.NET application. Currently ive been using the following methods to achieve this but they all feel a bit like a fudge. The way i pass data from javascript to the C# code behind is by setting hidden asp variables and triggering a postback <asp:HiddenField ID="RandomList" runat="server" /> function SetDataField(data) { document.getElementById('<%=RandomList.ClientID%>').value = data; } Then in C# code i collect the list protected void GetData(object sender, EventArgs e) { var _list = RandomList.value; } Going back the other way i often use either scriptmanager to register a function and pass it data during Page_Load: ScriptManager.RegisterStartupScript(this.GetType(), "Set","get("Test();",true); or i add attributes to controls before a post back or during Initialization / pre rendering stages: Btn.Attributes.Add("onclick", "DisplayMessage("Hello");"); These methods have served me well and do the job. However they just dont feel complete. Is there a more standardized way of passing data between client side markup / javascript and backend code. Ive seen some posts like this one: Injecting JavaScrip : StackOverflow that describe HtmlElement class. Is this something is should look into? Thanks everyone for your time.

• Cross-platform desktop programming: C++ vs. Python

  - by John Wells

  Alright, to start off, I have experience as an amateur Obj-C/Cocoa and Ruby w/Rails programmer. These are great, but they aren't really helpful for writing cross-platform applications (hopefully GNUStep will one day be complete enough for the first to be multi platform, but that day is not today). C++, from what I can gather, is extremely powerful but also a huge, ugly behemoth that can take half a decade or more to master. I've also read that you can very easily not only shoot yourself in the foot, but blow your entire leg off with it since memory management is all manual. Obviously, this is all quite intimidating. Is it correct? Python seems to provide most of the power of C++ and is much easier to pick up at the cost of speed. How big is this sacrifice? Is it meaningful or can it be ignored? Which will have me writing fast, stable, highly reliable applications in a reasonable amount of time? Also, is it better to use Qt for your UI or instead maintain separate, native front ends for each platform? EDIT: For extra clarity, there are two types applications I want to write: one is an extremely friendly and convenient database frontend and the other, which no doubt will come much later on, is a 3D world editor.

• Block elements vs inline elements in HTML: why the distinction?

  - by EpsilonVector

  The distinction between block and inline elements always seemed strange to me. The whole difference is that a block element takes up the entire width thus forcing a line break before and after the element, and an inline element only takes up as much as the content. Why not just have one type of element- an inline element where you can also apply custom height/width, and use that? You want line breaks? Insert a <br />, or maybe add a special tag in the CSS for that behavior. The way it's now, I don't see it solving any problem, and instead it only forces a property that in my opinion should be decided by a designer. So why the two types?

• Interfaces, Adapters, exposing business objects via WCF design

  - by Onam

  I know there have been countless discussions about this but I think this question is slightly different and may perhaps prompt a heated discussion (lets keep it friendly). The scene: I am developing a system as a means for me to learn various concepts and I came across a predicament which my brain is conflicting with. That is whether to keep my interfaces in a separate class library or should they live side by side my business objects. I want to expose certain objects via WCF, however refuse to expose them in its entirety. I am sure most will agree exposing properties such as IDs and other properties is not good practice but also I don't want to have my business objects decorated with attributes. The question: Essentially, I'll be having a separate interface for each of my objects that will essentially be exposed to the outside world (could end up being quite a few) so does it make sense to create a separate class library for interfaces? This also brings up the question of whether adapters should live in a separate class library too as ideally I want a mechanism from transferring from one object to the other and vice versa?

• Is hashing of just "username + password" as safe as salted hashing

  - by randomA

  I want to hash "user + password". EDIT: prehashing "user" would be an improvement, so my question is also for hashing "hash(user) + password". If cross-site same user is a problem then the hashing changed to hashing "hash(serviceName + user) + password" From what I read about salted hash, using "user + password" as input to hash function will help us avoid problem with reverse hash table hacking. The same thing can be said about rainbow table. Any reason why this is not as good as salted hashing?

• So what *did* Alan Kay really mean by the term "object-oriented"?

  - by Charlie Flowers

  Reportedly, Alan Kay is the inventor of the term "object oriented". And he is often quoted as having said that what we call OO today is not what he meant. For example, I just found this on Google: I made up the term 'object-oriented', and I can tell you I didn't have C++ in mind -- Alan Kay, OOPSLA '97 I vaguely remember hearing something pretty insightful about what he did mean. Something along the lines of "message passing". Do you know what he meant? Can you fill in more details of what he meant and how it differs from today's common OO? Please share some references if you have any. Thanks.

• Should I group all of my .js files into one large bundle?

  - by Scottie

  One of the difficulties I'm running into with my current project is that the previous developer spaghetti'd the javascript code in lots of different files. We have modal dialogs that are reused in different places and I find that the same .js file is often loaded twice. My thinking is that I'd like to just load all of the .js files in _Layout.cshtml, and that way I know it's loaded once and only once. Also, the client should only have to download this file once as well. It should be cached and therefore shouldn't really be a performance hit, except for the first page load. I should probably note that I am using ASP.Net bundling as well and loading most of the jQuery/bootstrap/etc from CDN's. Is there anything else that I'm not thinking of that would cause problems here? Should I bundle everything into a single file?

• Can I remove all-caps and shorten the disclaimer on my License?

  - by stefano palazzo

  I am using the MIT License for a particular piece of code. Now, this license has a big disclaimer in all-caps: THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF... ... I've seen a normally capitalised disclaimer on the zlib license (notice that it is above the license text), and even software with no disclaimer at all (which implies, i take it, that there is indeed a guarantee?), but i'd like some sourced advice by a trusted party. I just haven't found any. GNU's License notice for other files comes with this disclaimer: This file is offered as-is, without any warranty. Short and simple. My question therefore: Are there any trusted sources indicating that a short rather than long, and a normally spelled rather than capitalised disclaimer (or even one or the other) are safely usable in all of the jurisdictions I should be concerned with? If the answer turns out to be yes: Why not simply use the short license notice that the fsf proposes for readme-files and short help documents instead of the MIT License? Is there any evidence suggesting this short 'license' will not hold up? For the purposes of this question, the software is released in the European Union, should it make any difference.

• Are books on programming hard to understand?

  - by DarkEnergy

  I've been reading books that are extremely daunting. Accelerated C++ is by far one of the books -- that I haven't finished. I plan too, but that's another story. When reading a programming book, do you find yourself re reading a lot of the paragraphs? Sometimes it takes me like an hour to read 20 pages out of a book. Sometimes they become so daunting that it takes me all day to finish a single chapter. I think having these as e-books makes them even harder to read sometimes, since I'm so used to looking down to read a book or just looking at tangible paper. IDK, just wanting to know if reading these books becomes extremely hard, and do you find yourself rereading the most simplest paragraphs 2-3 times just to get the meaning of it because the previous paragraph left your brain hurting? http://www.it-career-coach.net/2007/03/04/are-computer-programming-books-hard-to-study/ here is a article i read on something similar to this. edit sometimes I find myself reading a whole page... then I look up and say 'wth did I just read'... I could finish a chapter in 30 minutes to an hour and feel this way too...

• Modified Strategy Design Pattern

  - by Samuel Walker

  I've started looking into Design Patterns recently, and one thing I'm coding would suit the Strategy pattern perfectly, except for one small difference. Essentially, some (but not all) of my algorithms, need an extra parameter or two passed to them. So I'll either need to pass them an extra parameter when I invoke their calculate method or store them as variables inside the ConcreteAlgorithm class, and be able to update them before I call the algorithm. Is there a design pattern for this need / How could I implement this while sticking to the Strategy Pattern? I've considered passing the client object to all the algorithms, and storing the variables in there, then using that only when the particular algorithm needs it. However, I think this is both unwieldy, and defeats the point of the strategy pattern. Just to be clear I'm implementing in Java, and so don't have the luxury of optional parameters (which would solve this nicely).
