  • License for Opensource project

    - by asterisk
    I am newbie in the open source community world. I am planning to develop a open source project, hosted on github. The project would be using other open source components like- NHibernate, FNH, Log4net, CommonLibrary, Autofac, Quartz.Net Scheduler etc etc My questions are: Would there be any restrictions on using above OSS components? for example: I plan to use MIT license, but Quartz.Net Scheduler uses Apache license, would there be any restrictions? How do I get a license for my own project? Do I need to register my project somewhere? What is the best practice to mention credits to the OSS compoenents used? Many thanks,

  • Daily standups- yea or nay?

    - by Fishtoaster
    How valuable (or not) do you think daily stand-up meetings are? If you're not familiar with it, this refers to a daily meeting often pushed by Scrum adherents (and some other general agile proponents). The idea is that you hold a daily meeting, timeboxed to 15 minutes, and in which everyone must stand (to encourage people to be to-the-point). In the meeting, you go around the room and each say: - What you did yesterday - What you plan to do today - Any blockers or impediments to your progress. Do you think this practice has value? Has anyone worked at a place that's done it, and what did you think?

  • help with matlab and Discrete Fourier transform

    - by user504363
    Hi all I have previous experience with Matlab, but the problem that I face some problems in apply a problem in (DSP : Digital signal processing) which is not my study field, but I must finish that problems in days to complete my project. all i want is help me with method and steps of solving this problem in matlab and then I can write the code with myself. the problem is about the signal x(t) = exp(-a*t); 1) what's the Discrete Fourier transform of the sampled signal with sample rate fs 2) if a=1 and fs =1 , plot the amplitude spectrum of sampled signal 3) fix the sampling frequency at fs = 1(hz) [what's it mean ?] and plot the magnitude of the Fourier Transform of the sampled signal at various values of a thanks

  • Shader inputs in a general purpouse engine

    - by dreta
    I'm not familiar with SDKs like Unity or UDK that much, so i can't check this off hand. Do general purpouse engines allow users to create custom uniform variables? The way i see it, and the way i have implemented it in an engine i'm writing to learn 3D, is that there is a "set" of uniforms provided by the engine and if you want to write a custom shader then you utilize uniforms you need to create a wanted effect. Now, the thing is, first of all i'm not an artist, second of all, i didn't have a chance to create complex scenes yet. So my question is, is it common practice to define variables that the engine provides and only allow the user to work with what they're given? Allowing users to add custom programs and use them where they want is not hard, but i have issues imagining how you'd go about doing the same for uniforms.

  • Is hierarchical product backlog a good idea in TFS 2012-2013?

    - by Matías Fidemraizer
    I'd like to validate I'm not in the wrong way. My team project is using Visual Studio Scrum 2.x. Since each area/product has a lot of kind of requirements (security, user interface, HTTP/REST services...), I tried to manage this creating "parent backlogs" which are "open forever" and they contain generic requirements. Those parent backlogs have other "open forever" backlogs, and/or sprint backlogs. For example: HTTP/REST Services (forever) ___ Profiles API (forever) ________ POST profile (forever) _______________ We need a basic HTTP/REST profiles' API to register new user profiles (sprint backlog) Is it the right way of organizing the product backlog? Note: I know there're different points of view and that would be right for some and wrong for others. I'm looking for validation about if this is a possible good practice on TFS with Visual Studio Scrum.

  • Can it be useful to build an application starting with the GUI?

    - by Grant Palin
    The trend in application design and development seems to be starting with the "guts": the domain, then data access, then infrastructure, etc. The GUI seems to usually come later in the process. I wonder if it could ever be useful to build the GUI first... My rationale is that by building at least a prototype GUI, you gain a better idea of what needs to happen behind the scenes, and so are in a better position to start work on the domain and supporting code. I can see an issue with this practice in that if the supporting code is not yet written, there won't be much for the GUI layer to actually do. Perhaps building mock objects or throwaway classes (somewhat like is done in unit testing) would provide just enough of a foundation to build the GUI on initially. Might this be a feasible idea for a real project? Maybe we could add GDD (GUI Driven Development) to the acronym stable...

  • Handling session between two pages in iframe-based facebook app.

    - by Ray Yun
    I'm a newbie to iframe based facebook application and stuck with session related problems. There are just two pages in my app. First page got many fb_sig_* parameters from facebook platform but when I click a anchor to next page, those fb_sig_* were lost because this is just direct request from end user's browser not from facebook. So I found that http://forum.developers.facebook.com/viewtopic.php?id=52885. It was told that I should not using cookie and always append every fb_sig* to every anchor. This can be the only solution for my problems? Any side effect like session expiry problem?

  • Is "PHP and MySQL Web Development, 4th ed." an outdated book to learn from?

    - by ForeverLearnNeverMaster
    I want to get into web stuff, and thought of going with PHP+MySQL. I have experience in C#, C++, desktop graphics, but no web stuff besides HTML, CSS which I started learning 2 months ago. On SO PHP-book question, the highest rated book is "PHP Objects, Patterns and Practice". However, I'm not sure if it's a book to start PHP with... or is it? Most of the books mentioned in that SO question seem to be for those who already know PHP. I considered "PHP & MySQL Web Development, 4th Ed.", but someone mentioned that "it uses the mysql_* functions which are almost deprecated." Help?

  • Category to Page and blocking category url via robots.txt -Good for SEO?

    - by user2952353
    I am using a template which in the pages it allows me to add sidebars / more content under and above the content I want to pull from a category which is very helpful. If I create pages to display my categories content wont the page urls go in conflict with the category urls? By conflict I mean causing a duplicate content error? What I thought might help was to block from robots.txt the category urls of the blog ex. /category/books /category/music Would that be a good practice in order to avoid the duplicate content penalty? Any tips appreciated.

  • Should all, none, or some overriden methods call Super?

    - by JoJo
    When designing a class, how do you decide when all overridden methods should call super or when none of the overridden methods should call super? Also, is it considered bad practice if your code logic requires a mixture of supered and non-supered methods like the Javascript example below? ChildClass = new Class.create(ParentClass, { /** * @Override */ initialize: function($super) { $super(); this.foo = 99; }, /** * @Override */ methodOne: function($super) { $super(); this.foo++; }, /** * @Override */ methodTwo: function($super) { this.foo--; } }); After delving into the iPhone and Android SDKs, I noticed that super must be called on every overridden method, or else the program will crash because something wouldn't get initialized. When deriving from a template/delegate, none of the methods are supered (obviously). So what exactly are these "je ne sais quoi" qualities that determine whether a all, none, or some overriden methods should call super?

  • Dependency Injection Confusion

    - by James
    I think I have a decent grasp of what Dependency Inversion principle (DIP) is, my confusion is more around dependency injection. My understanding is the whole point of DI is to decouple parts of an application, to allow changes in one part without effecting another, assuming the interface does not change. For examples sake, we have this public class MyClass(IMyInterface interface) { public MyClass { interface.DoSomething(); } } public interface IMyInterface { void DoSomething(); } How is this var iocContainer = new UnityContainer(); iocContainer.Resolve<MyClass>(); better practice than doing this //if multiple implementations are possible, could use a factory here. IMyInterface interface = new InterfaceImplementation(); var myClass = new MyClass(interface); It may be I am missing a very important point, but I am failing to see what is gained. I am aware that using an IOC container I can easily handle an objects life cycle, which is a +1 but I don't think that is core to what IOC is about.

  • Mercurial release management. Rejecting changes that fail testing

    - by MYou
    Researching distributed source control management (specifically mercurial). My question is more or less what is the best practice for rejecting entire sets of code that fail testing? Example: A team is working on a hello world program. They have testers and a scheduled release coming up with specific features planned. Upcoming Release: Add feature A Add feature B Add feature C So, the developers make their clones for their features, do the work and merge them into a QA repo for the testers to scrutinize. Let's say the testers report back that "Feature B is incomplete and in fact dangerous", and they would like to retest A and C. End example. What's the best way to do all this so that feature B can easily be removed and you end up with a new repo that contains only feature A and C merged together? Recreate the test repo? Back out B? Other magic?

  • Hybrid IT or Cloud Initiative – a Perfect Enterprise Architecture Maturation Opportunity

By this, I mean the EA activities - whether targeted towards compliance, risk mitigation or value opportunity propositions – may not be attached to measurable, active, visible projects that could advance and prove the value of EA. EA doesn’t work by itself, in a vacuum, without collaborative engagement and a means of proving usefulness. A critical vehicle to this proof is successful orchestration and use of assets and investment resources to meet a high-profile business objective – i.e. a successful project. More and more organizations are now exploring and considering some degree of IT outsourcing, buying and using external services and solutions to deliver their IT and business requirements – vs. building and operating in-house, in their own data centers. The rapid growth and success of “Cloud” services makes some decisions easier and some IT projects more successful, while dramatically lowering IT risks and enabling rapid growth. This is particularly true for “Software as a Service” (SaaS) applications, which essentially are complete web applications hosted and delivered over the Internet. Whether SaaS solutions – or any kind of cloud solution - are actually, ultimately the most cost-effective approach truly depends on the organization’s business and IT investment strategy. This leads us to Enterprise Architecture, the connectivity between business strategy and investment objectives, and the capabilities purchased or created to meet them. If an EA framework already exists, the approach to selecting a cloud-based solution and integrating it with internal IT systems (i.e. a “Hybrid IT” solution) is well-served by leveraging EA methods. If an EA framework doesn’t exist, or is simply not mature enough to address complex, integrated IT objectives – a hybrid IT/cloud initiative is the perfect project to advance and prove the value of EA. Why is this? For starters, the success of any complex IT integration project - spanning multiple systems, contracts and organizations, public and private – depends on active collaboration and coordination among the project stakeholders. For a hybrid IT initiative, inclusive of one or more cloud services providers, the IT services, business workflow and data governance challenges alone can be extremely complex, requiring many diverse layers of organizational expertise and authority. Establishing subject matter expertise, authorities and strategic guidance across all the disciplines involved in a hybrid-IT or hybrid-cloud system requires top-level, comprehensive experience and collaborative leadership. Tools and practices reflecting industry expertise and EA alignment can also be very helpful – such as Oracle’s “Cloud Candidate Selection Tool”. Using tools like this, and facilitating this critical collaboration by leading, organizing and coordinating the input and expertise into a shared, referenceable, reusable set of authority models and practices – this is where EA shines, and where Enterprise Architects can be most valuable. The “enterprise”, in this case, becomes something greater than the core organization – it includes internal systems, public cloud services, 3rd-party IT platforms and datacenters, distributed users and devices; a whole greater than the sum of its parts. Through facilitated project collaboration, leading to identification or creation of solid governance models and processes, a durable and useful Enterprise Architecture framework will usually emerge by itself, if not actually identified and managed as such. The transition from planning collaboration to actual coordination, where the program plan, schedule and resources become synchronized and aligned to other investments in the organization portfolio, is where EA methods and artifacts appear and become most useful. The actual scope and use of these artifacts, in the context of this project, can then set the stage for the most desirable, helpful and pragmatic form of the now-maturing EA framework and community of practice. Considering or starting a hybrid-IT or hybrid-cloud initiative? Running into some complex relationship challenges? This is the perfect time to take advantage of your new, growing or possibly latent Enterprise Architecture practice.

  • Orbital equations, and power required to run them

    - by Adam Davis
    Due to a discussion on the SO IRC today, I'm curious about orbital mechanics, and The equations needed to solve orbital problems The computing power required to solve complex problems The question in particular is calculating when the Earth will plow into the Sun (or vice versa, depending on the frame of reference). I suspect that all the gravitational pulls within our solar system may need to be calculated, which makes me wonder what type of computer cluster is required, or can this be done on a single box? I don't have the experience to do a back of the napkin test here, but perhaps you do? Also, much thx to Gortok for the original inspiration (see comments).

  • How do I analyze vague Google Analytics data re traffic from Facebook?

    - by user6982
    We have one Facebook fan page and two personal profiles that could be sending traffic and then there are the many facebook pages of friends etc. I am also running an ad campaign from my FB account for my husband's business which has a link from his personal FB profile and his fan page. On Google analytics for his business we get the following referring sites from Facebook: /ajax/emu/end.php which is listed under facebook.com / referral /l.php (which is a not-found page at FB /ajax/emu/end.php which is listed under apps.facebook.com Both of the working links send me to the home page of my profile, which is the account I am working from to create and review the FB ad campaign that we are running. Is this info telling me any useful information at all? Is there a best practice for tracking and analyzing Facebook traffic that is a lot more granular? thanks!

  • Queuing rpc calls

    - by alfa64
    i'm designing a system wich listen to json rpc calls from clients, piles it up inside a list, and if it gets full it should store them in a DB and keep recieving calls. My original plan is to listen to the rpc calls from Perl with the json-rpc and put them in the array. The clients do some long polling in another server to get responses as they appear. What is this blocking/noblocking thing? Should i do a script for node.js to listen to the calls? What do you think is a good practice in this case? The objective is to listen as much calls as possible.

  • Does Agile (scrum) require one server environment?

    - by Matt W
    Is it necessary/recommend/best practice/any other positive to use only one server environment to perform all development, unit testing and QA? If so, is it then wise/part of Agile to then have only one staging environment before Live? Considering that this could mean internationally distributed teams of developers and testers in different time zones is this wise? This is something being implemented by our QA manager. The opinion put forward is that doing all the dev and testing on a single server is "Agile." The staging environment would be a second environment, and then live.

  • 301 Redirects for regional variants of a homepage

    - by Adam Jenkin
    I am planning on implementing a website which has regional homepage variants. For Example: mycompany.com/europe mycompany.com/us The rest of the site is region agnostic and content will continue such as: mycompany.com/news mycompany.com/about-us etc For homepage (.com) requests, I plan on redirecting users to the correct homepage variant (via 301). If I cannot determine the correct one, I will fallback to redirecting them to the US homepage (/us). From an SEO point of view, firstly is this ok? or should I be doing anything additional to this for making search engines aware of the regional differences? As crawlers are region agnostic, I plan on directing them to the US page with a 301, or should I have something on the .com page which they use? Being that the regional homepage's will likely be the most visited pages, they should show up in result sitelinks when searching for mycompany (which I think is a good thing). Apologies for the slightly open question - I know anything SEO related is more opinion/best practice than fact but am purely looking for advice.

  • Should a primary key be immutable?

    - by Vincent Malgrat
    A recent question on stackoverflow provoked a discussion about the immutability of primary keys. I had thought that it was a kind of rule that primary keys should be immutable. If there is a chance that some day a primary key would be updated, I thought you should use a surrogate key. However it is not in the SQL standard and some RDBMS' "cascade update" feature allows a primary key to change. So my question is: is it still a bad practice to have a primary key that may change ? What are the cons, if any, of having a mutable primary key ?

  • Devise and cancan gems: has_many association

    I use devise and cancan gems and have simple model association: user has_many subscriptions, subscription belongs_to :user. Have following SubscriptionsController: class SubscriptionsController < ApplicationController load_and_authorize_resource :user load_and_authorize_resource :subscription, through: :user before_filter :authenticate_user! def index @subscriptions = @user.subscriptions.paginate(:page => params[:page]).order(:created_at) end #other actions end And Cancan Ability.rb: class Ability include CanCan::Ability def initialize(user) user ||=User.new can [:index, :show], [Edition, Kind] if user.admin? can :manage, :all elsif user.id can [:read, :create, :destroy, :pay], Subscription, user_id: user.id can [:delete_from_cart, :add_to_cart, :cart], User, id: user.id end end end The problem is that i cannot use subscriptions actions as a user but can as a admin. And have no problems with UsersController. When i delete following lines from SubscriptionsController: load_and_authorize_resource :user load_and_authorize_resource :subscription, through: :user before_filter :authenticate_user! Have no problems at all. So the issue in these lines or in Ability.rb. Any suggestions?

  • How do I know if I'm being truly clever and not just "clever"?

    - by Covar
    If there's one thing I've learned from programming is that there are clever solutions to problems, and then there are "clever" solutions to problems. One is an intelligent solution to a difficult problem that results in improved efficiency and a better way to to do something and the other will wind up on The Daily WTF, and result in headaches and pain for anyone else involved. My question is how do you distinguish between one and the other? How do you figure out if you've over thought the solution? How do you stop yourself from throwing away truly clever solutions, thinking they were "clever"?
