  • Is implementing an interface defined in a subpackage an anti-pattern?

    - by Michael Kjörling
    Let's say I have the following: package me.my.pkg; public interface Something { /* ... couple of methods go here ... */ } and: package me.my; import me.my.pkg.Something; public class SomeClass implements Something { /* ... implementation of Something goes here ... */ /* ... some more method implementations go here too ... */ } That is, the class implementing an interface lives closer to the package hierarchy root than does the interface it implements but they both belong in the same package hierarchy. The reason for this in the particular case I have in mind is that there is a previously-existing package that groups functionality which the Something interface logically belongs to, and the logical (as in both "the one you'd expect" and "the one where it needs to go given the current architecture") implementation class exists previously and lives one level "up" from the logical placement of the interface. The implementing class does not logically belong anywhere under me.my.pkg. In my particular case, the class in question implements several interfaces, but that feels like it doesn't make any (or at least no significant) difference here. I can't decide if this is an acceptable pattern or not. Is it or is it not, and why?

  • It is inconsiderate to place editor settings inside code files?

    - by Carlos Campderrós
    I know this is kind of a subjective question, but I'm curious if there's any good reason to place (or not place) editor settings inside code files. I'm thinking in vi modelines, but it is possible that this applies to other editors. In short, a vi modeline is a line inside a file that tells vi how to behave (indent with spaces or tabs, set tabwidth to X, autoindent by default or not, ...) that is placed inside a comment, so it won't affect the program/compiler when running. In a .c file it could be similar to // vim: noai:ts=4:sw=4 On one hand, I think this shouldn't be inside the file, as it is an editor setting and so belongs to an editor configuration file or property. On the other hand, for projects involving developers outside one company (that are not imposed an editor/settings) or collaborators on github/bitbucket/... it is an easy way to avoid breaking the code style (tabs vs spaces for example), but only for the ones that use that editor though. I cannot see any powerful enough reason to decide for or against this practice, so I am in doubt of what to do.

  • How difficult is it for an artist to make their own artwork cohesive to another artists' style? [on hold]

    - by user36200
    I have a lot of artwork I purchased from a website, but the artist who drew the game assets is unavailable. I need to create additional artwork which fits with this style, but I am not an artist- nor do I have any idea of how artists work. Obviously, the solution is to find a new artist, who I can pay to draw this artwork while keeping it to look at certain way. I am scared of wasting money though. I don't want to contract an artist, only to find out it is extremely difficult for someone to match another person's art style. I don't need it to be identical, I just need it to be cohesive. I also want to know what I'm asking of people, before I ask them. Artists are workers just like me, and deserve to be understood when contracted. As an artist, is it extra difficult or time consuming to alter your artwork to match a certain style? Does it require a lot of talent to make a cohesive piece of art? To be specific, I am talking about structures, such as 2D symbols of towns for a map. They all have this "gritty" penciling effect to them and lots of saturated colors, which is what will be required when I say "cohesive". Along with looking like the architecture belongs in the same world.

  • Installing Windows from Ubuntu while booting only from the hard drive

    - by WindowsEscapist
    My problem is unrelated to this workaround (the question) here, but the end result is that I cannot change boot order (or use a boot menu) on my laptop. It is currently running Ubuntu 12.04 with a dual-boot to Fedora if anything goes catastrophically wrong with Ubuntu (read "if I mess it up"). I would really like to install Windows 7 (but XP would be fine) on an empty FAT32 partition I have already made because of issues with WINE-emulated programs running more slowly than under Windows. The problem is, I can only boot from my hard drive. I can boot from other devices by removing the hard drive, but this is irrelevant because SATA is non-hotpluggable (I can't plug it back in to install). Is there any way I could boot up a Windows installer CD (or other CDs)? (I know how to keep my Linux distros.) I have both the .iso's and the physical CDs (or can obtain them). This may be unneeded, but just as a disclaimer this is completely legal. The computer belongs to me, I have admin privs, etc. I'm not doing anything shady!

  • Use constructor or setter method?

    - by user633600
    I am working on a UI code where I have an Action class, something like this - public class MyAction extends Action { public MyAction() { setText("My Action Text"); setToolTip("My Action Tool tip"); setImage("Some Image"); } } When this Action class was created it was pretty much assumed that the Action class wont be customizable (in a sense- its text, tooltip or image will be not be changed anywhere in the code). Of late, now we are in need of changing the action text at some location in code. So I suggested my co-worker to remove the hardcoded action text from the constructor and accept it as an argument, so that everybody is forced to pass the action text. Something like this code below - public class MyAction extends Action { public MyAction(String actionText) { setText(actionText); setTooltip("My Action tool tip); setImage("My Image"); } } He however thinks that since setText() method belongs to base class. It can be flexibly used to pass the action text wherever action instance is created. That way, there is no need to change the existing MyAction class. So his code would look something like this. MyAction action = new MyAction(); //this creates action instance with the hardcoded text action.setText("User required new action text"); //overwrite the exisitng text. I am not sure if that is a correct way to deal with problem. I think in above mentioned case user is anyway going to change the text, so why not force him while constructing the action. The only benefit I see with the original code is that user can create Action class without much thinking about setting text.

  • Mobile (Client) to Amazon S3 (Server) - Architecture

    - by wasabii
    let's start off with the problem statement: My iOS application has a login form. When the user logs in, a call is made to my API and access granted or denied. If access was granted, I want the user to be able to upload pictures to his account and/or manage them. As storage I've picked Amazon S3, and I figured it'd be a good idea to have one bucket called "myappphotos" for instance, which contains lots of folders. The folder names are hashes of a user's email and a secret key. So, every user has his own, unique folder in my Amazon S3 bucket. Since I've just recently started working with AWS, here's my question: What are the best practices for setting up a system like this? I want the user to be able to upload pictures directly to Amazon S3, but of course I cannot hard-code the access key. So I need my API to somehow talk to Amazon and request an access token of sorts - only for the particular folder that belongs to the user I'm making the request for. Can anyone help me out and/or guide me to some sources where a similar problem was addressed? Don't think I'm the first one and the amazon documentation is so extensive that I don't really know where to start looking. Thanks a lot!

  • Model View Controller² [closed]

    - by user694971
    I am working on a quite complex web application in Go and I tried to stay in an MVC pattern. However, I ended up having a structure isomorphic to this: /boilerplate The usual boilerplate an application needs to survive in the wilderness /db Layer talking to an SQL DB /helpers Helpers /logic Backend logic, not directly affiliated with any routes, sessions etc. /templates View /web Glue between /logic and /templates. In more dynamic languages the size of /web would be next to zero. But Go doesn't exactly have a RoR integrated so I need a lot of helper structures to feed the templates with data, to process GET/POST parameters and session information. I remember once reading about patterns similar to MVC with one extra letter but Wiki-searching I couldn't find it right now. (BTW currently /logic also contains data retrieval from API services to fill some hash maps; this is no simple task, but that probably belongs into the model, right?) So question: is this structure considered sane? Or does it need some bending to be tagged MVC app?

  • More SharePoint 2010 Expression Builders

    - by Ricardo Peres
    Introduction Following my last post, I decided to publish the whole set of expression builders that I use with SharePoint. For all who don’t know about expression builders, they allow us to employ a declarative approach, so that we don’t have to write code for “gluing” things together, like getting a value from the query string, the page’s underlying SPListItem or the current SPContext and assigning it to a control’s property. These expression builders are for some quite common scenarios, I use them quite often, and I hope you find them useful as well. SPContextExpression This expression builder allows us to specify an expression to be processed on the SPContext.Current property object. For example: 1: <asp:Literal runat="server" Text=“<%$ SPContextExpression:Site.RootWeb.Lists[0].Author.LoginName %>”/> It is identical to having the following code: 1: String authorName = SPContext.Current.Site.RootWeb.Lists[0].Author.LoginName; SPFarmProperty Returns a property stored on the farm level: 1: <asp:Literal runat="server" Text="<%$ SPFarmProperty:SomeProperty %>"/> Identical to: 1: Object someProperty = SPFarm.Local.Properties["SomeProperty"]; SPField Returns the value of a selected page’s list item field: 1: <asp:Literal runat="server" Text="<%$ SPField:Title %>"/> Does the same as: 1: String title = SPContext.Current.ListItem["Title"] as String; SPIsInAudience Checks if the current user belongs to an audience: 1: <asp:CheckBox runat="server" Checked="<%$ SPIsInAudience:SomeAudience %>"/> Equivalent to: 1: AudienceManager audienceManager = new AudienceManager(SPServiceContext.Current); 2: Audience audience = audienceManager.Audiences["SomeAudience"]; 3: Boolean isMember = audience.IsMember(SPContext.Current.Web.User.LoginName); SPIsInGroup Checks if the current user belongs to a group: 1: <asp:CheckBox runat="server" Checked="<%$ SPIsInGroup:SomeGroup %>"/> The equivalent C# code is: 1: SPContext.Current.Web.CurrentUser.Groups.OfType<SPGroup>().Any(x => String.Equals(x.Name, “SomeGroup”, StringComparison.OrdinalIgnoreCase)); SPProperty Returns the value of a user profile property for the current user: 1: <asp:Literal runat="server" Text="<%$ SPProperty:LastName %>"/> Where the same code in C# would be: 1: UserProfileManager upm = new UserProfileManager(SPServiceContext.Current); 2: UserProfile u = upm.GetUserProfile(false); 3: Object property = u["LastName"].Value; SPQueryString Returns a value passed on the query string: 1: <asp:GridView runat="server" PageIndex="<%$ SPQueryString:PageIndex %>" /> Is equivalent to (no SharePoint code this time): 1: Int32 pageIndex = Convert.ChangeType(typeof(Int32), HttpContext.Current.Request.QueryString["PageIndex"]); SPWebProperty Returns the value of a property stored at the site level: 1: <asp:Literal runat="server" Text="<%$ SPWebProperty:__ImagesListId %>"/> You can get the same result as: 1: String imagesListId = SPContext.Current.Web.AllProperties["__ImagesListId"] as String; Code OK, let’s move to the code.

  • Hexagonal Grid Coordinates To Pixel Coordinates

    - by CaptnCraig
    I am working with a hexagonal grid. I have chosen to use this coordinate system because it is quite elegant. This question talks about generating the coordinates themselves, and is quite useful. My issue now is in converting these coordinates to and from actual pixel coordinates. I am looking for a simple way to find the center of a hexagon with coordinates x,y,z. Assume (0,0) in pixel coordinates is at (0,0,0) in hex coords, and that each hexagon has an edge of length s. It seems to me like x,y, and z should each move my coordinate a certain distance along an axis, but they are interrelated in an odd way I can't quite wrap my head around it. Bonus points if you can go the other direction and convert any (x,y) point in pixel coordinates to the hex that point belongs in.

  • iphone - UITapGestureRecognizer problem

    - by Mike
    I have two UIImageViews one as subview of the other. The subview is smaller and is centered on the screen. Both have UITapGestureRecognizer assigned and both were intended to respond to single taps. A single tap on the main view (= the area outside the subview) is fine, but a tap inside the subview is seen as the main view as a tap too. How can I have this to work independently? both views have setCancelsTouchesInView and setDelaysTouchesEnded set to NO and both have the same delegate (yes, I need to have the same delegate and cannot change that). How may I force the main view to ignore any tap on the area that belongs to its subview? thanks for any help.

  • Refinery CMS (Rails): Creating a plugin or plugins with multiple models and relationships

    - by jklina
    My goal is to create a way for an admin to create two models in the Refinery admin: Campaigns and Videos I would like to have it setup so that a Campaign has many Videos and that each Video belongs to a Campaign. Both Videos and Campaigns will have a title, description, and a preview image. I'm not certain of the best way to go about this. Is it possible to setup two plugins and form a relationship between the two? Or, should I create one plugin with both models. If someone could point me in the right direction or a good example of a solution to a similar problem, I would be grateful. Thank you for looking!

  • How to set permissions so two users can work on the same hg repository?

    - by John Mee
    Ubuntu: Jaunty Mercurial: 1.3.1 Access: ssh (users john and bob) File permission: -rw-rw---- 1 john john 129276 May 17 13:28 dirstate User: bob Command: 'hg st' Response: **abort: Permission denied: /our/respository/.hg/dirstate** Obviously mercurial can't let bob see the state because the file it needs to read belongs to me. So I change the permissions to allow bob to read the file and everything is fine, up until I next try to do something, whence the situations are reversed. Now he owns the file and I can't read it. So I set up a "committers" group and both john and bob belong to the group, but still mercurial fiddles with the ownership and permissions whenever one or other commits. How do we configure it so two different logins in the same group can commit to the same repository over ssh?

  • User.IsInRole returning false

    My ASP.NET app is using windows authentication. If I run the following code: WindowsIdentity wi = (WindowsIdentity)User.Identity; foreach (IdentityReference r in wi.Groups) { ListBox1.Items.Add(r.Translate (typeof (NTAccount)).Value); } if (User.IsInRole ("Everyone")) Label1.Text = "Is in role"; The listbox will contain the name of every group the user belongs to. If I then call User.IsInRole, and pass in the name of any of those groups, I always get a false. Can anyone tell me what I am doing wrong? Thanks

  • Access Control Lists basics

    - by vtortola
    Hi, I'm gonna add authorization, user and groups management to my application, basically... you will can define a set of permissions for a concrete user or group. For example, you could specify whom can use a concrete resource. So I want to ensure that my assumptions about ACLs are right: A basic rule could be "Grant", "Deny", "NoSet". User permissions have priority over group permissions. "Deny" statement has priority over "Grant". For example, user "u1" belongs to group "A", the resource "X" has this ACL "u1:grant,A:deny" user "u1" should be able to access the resource, shouldn't it? If a resource has no ACL set... does it means that anyone can access it? should I provide a default ACL? Any document about ACL in a general way? Cheers.

  • python union of 2 nested lists with index

    - by sbas
    I want to get the union of 2 nested lists plus an index to the common values. I have two lists like A = [[1,2,3],[4,5,6],[7,8,9]] and B = [[1,2,3,4],[3,3,5,7]] but the length of each list is about 100 000. To A belongs an index vector with len(A): I = [2,3,4] What I want is to find all sublists in B where the first 3 elements are equal to a sublist in A. In this example I want to get B[0] returned ([1,2,3,4]) because its first three elements are equal to A[0]. In addition, I also want the index to A[0] in this example, that is I[0]. I tried different things, but nothing worked so far :( First I tried this: Common = [] for i in range(len(B)): if B[i][:3] in A: id = [I[x] for x,y in enumerate(A) if y == B[i][:3]][0] ctdCommon.append([int(id)] + B[i]) But that takes ages, or never finishes Then I transformed A and B into sets and took the union from both, which was very quick, but then I don't know how to get the corresponding indices Does anyone have an idea?

However, when I click Change Properties for that field I get an error message: This field belongs to a locked section and cannot have its properties modified. How can I get around this and edit it? Is there a workaround similar to customizing the Article view? Or can I hack the DB somehow to "unlock" that field?

  • Dectect ASCII codes for asian double byte / cyrillic character sets?

    - by jfroom
    Is it possible to detect if an ascii character belongs to Asian double byte or Cyrillic character sets? Perhaps specific code ranges? I've googled, but not finding anything at first glance. There's an RSS feed I'm tapping into that has the locale set as 'en-gb'. But there are some Asian double byte characters in the feed itself - which I need to handle differently. Just not sure how to detect it since the meta locale data is incorrect. I do not have access to correct the public feed.

  • Nhibernate Criteria Group By clause and select other data that is not grouped

    - by Peter R
    Hi, I have a parent child relationship, let's say class and children. Each child belongs to a class and has a grade. I need to select the children (or the ids of the children) with the lowest grade per class. session.CreateCriteria(typeof(Classs)) .CreateAlias("Children", "children") .SetProjection(Projections.ProjectionList() .Add(Projections.Min("children.Grade")) .Add(Projections.GroupProperty("Id")) ) .List<Object[]>(); This query returns me the lowest grade per class, but I don't know which child got the grade. When I add the children's Id to the group, the group is wrong and every child gets returned. I was hoping we could just select get the id's of those childs without grouping them. If this is not possible, then maybe there is a way to solve this with subqueries?

  • Datamining on a mysql database

    - by sliptix
    Hello, I Begin with textmining. I have two database tables with thousands of data.. a table for "skills" and a table for "skills categories" every "skill" belongs to a skills categorie. a "skill" is , physicaly, a varchar(200) field in the database, where there is some text describing the skill. Here are some skills extracted from the skills table: "PHP (good level), Java (intermediaite), C++" "PHP5" "project management and quality management" "begining Javascript" "water engineering" "dfsdf zerze rzer" "cibling customers" what i want to do is to extract knowledge from those fields, i mean extract only the real skill and ignore the rest of useless text. for the above example i want to get only an array with: "PHP" "Java" "C++" "PHP5" "project management" "quality management" "Javascript" "water engineering" "cibling customers" what should i do to extract the skills from tons of data please ? do you know specific algorithms to do this ? ex : k-means ... ? Thanks in advance.

  • F# currying efficiency?

    - by Eamon Nerbonne
    I have a function that looks as follows: let isInSet setElems normalize p = normalize p |> (Set.ofList setElems).Contains This function can be used to quickly check whether an element is semantically part of some set; for example, to check if a file path belongs to an html file: let getLowerExtension p = (Path.GetExtension p).ToLowerInvariant() let isHtmlPath = isInSet [".htm"; ".html"; ".xhtml"] getLowerExtension However, when I use a function such as the above, performance is poor since evaluation of the function body as written in "isInSet" seems to be delayed until all parameters are known - in particular, invariant bits such as (Set.ofList setElems).Contains are reevaluated each execution of isHtmlPath. How can best I maintain F#'s succint, readable nature while still getting the more efficient behavior in which the set construction is preevaluated. The above is just an example; I'm looking for a general pattern that avoids bogging me down in implementation details - where possible I'd like to avoid being distracted by details such as the implementation's execution order since that's usually not important to me and kind of undermines a major selling point of functional programming.

  • Linq join with COUNT

    - by shivesh
    I have 2 tables, Forums and Posts. I want to retrieve all Forums fields with a new extra field: count all post that belong to this forum. I have this for now: var v =(from forum in Forums join post in Posts on forum.ForumID equals post.Forum.ForumID select new { forum, //Need to retrieve all fields/columns from forum PostCount = //count all post that belong to this forum with a condition: count it only if post.Showit==1 } ).Distinct() The join must be Left join: if there are no post that belongs to some forum, the forums fields should be retrieved but PostCount field should be 0. The result set must be distinct (join gives me the full cross...or how it's called)

  • CALayer flickers when drawing a path

    - by Alexey
    I am using a CALayer to display a path via drawLayer:inContext delegate method, which resides in the view controller of the view that the layer belongs to. Each time the user moves their finger on the screen the path is updated and the layer is redrawn. However, the drawing doesn't keep up with the touches: there is always a slight lag in displaying the last two points of the path. It also flickers, but only while displaying the last two-three points again. If I just do the drawing in the view's drawRect, it works fine and the drawing is definitely fast enough. Does anyone know why it behaves like this? I suspect it is something to do with the layer buffering, but I couldn't find any documentation about it.

  • building a backend for generating webquests with rails

    - by buk
    hello, i want to learn rails and as a project to learn rails i came across webquests. what a webquest is is clearly written here1 and this is a example how a webquest look like. i started with script/generate nifty_scaffold introduction index and repeat this for every section like task , Process, Evaluation and so on. but i dont think thats the right way because i have a lot of code for the same thing. on the other side i am more flexible on designing views or controllers instead of having only one controller foer all pages. i am not asking here to get code. i am asking who to "build" such a backend where you can click on "New Webquest" a form comes up and you can enter all the text who belongs to the topic. maybee i can add some drawings later. i hope anyone can show me how to do that. or post me some links or some rtfms :D regards, buk

  • Effective file permissions tool's api in windows

    - by apoorv020
    Starting from Windows Server 2003, Windows included a new tool which calculates the effective permissions for a user (basically it resolves all groups access and takes care of all "deny" permissions as well). An example in point is that a user A belongs to groups B and C. B has been denied read permissions on a file F, while C has been allowed read and write permissions on the file and I want to calculate the effective permissions user A has on file F. This tool is available on Windows Server 2003,Vista,7 and Server 2008 by right clicking on a file and going to properties - security - advanced - effective permissions. What I need is an API in C# which does the same job. The most common FILE API returns access rules (class FileAccessRules), but there seems to be no direct way to calculate effective permissions from these set of access rules. Note: I do not want to process effective permissions in the code if at all possible, but am ready to do so as a last resort.
