  • How to slave a 3.5" 500gb SATA external hard drive (Western Digital) to my Dell Inspiron laptop

    - by AJ HDD
    I have a 3.5" Western Digital My Book 500gb external hard drive. I gave it to a friend of mine, and he broke the USB port in it. I went to a nearby comp repair shop and had him solder the thing, and it didn't detect when it when I plugged it into my Dell Inspiron laptop. I recently saw about the 3.5" SATA to USB enclosure, so I went to check it. Strangely, when its placed in the enclosure, its not detecting in Windows. Also, when it was put as secondary (I'm guessing slave) to the shop fellow's desktop, it shows up in the BIOS and while starting, but then again doesn't show in Windows 7. The guy told me that I need to use a data recovery tool to get my data back. P.S. Whe WD hard drive doesnt have an OS, just data. So my question is: Can I slave the drive to my Dell laptop and try to recover the data, and if so how? I would really appreciate it any help, thanks in advance.

  • Logic for capturing unique characteristics in an object array. C# LINQ [closed]

    - by Shawn H.
    Given the following "response" or array of objects, what would be the most efficient way to get the desired results. There must be an easier way than the exhaustive and tedious way I'm doing it now. A LINQ solution would be fantastic. Situation #1 <things> <thing id="1"> <feature>Tall</feature> </thing> <thing id="2"> <feature>Tall</feature> </thing> <thing id="3"> <feature>Tall</feature> <feature>Wide</feature> </thing> <thing id="4"> <feature>Tall</feature> </thing> </things> Result: Wide Situation #2 <things> <thing id="1"> <feature>Short</feature> </thing> <thing id="2"> <feature>Tall</feature> </thing> <thing id="3"> <feature>Tall</feature> <feature>Wide</feature> </thing> <thing id="4"> <feature>Tall</feature> </thing> </things> Result: Wide, Short, Tall Situation #3 <things> <thing id="1"> <feature>Tall</feature> <feature>Thin</feature> </thing> <thing id="2"> <feature>Tall</feature> </thing> <thing id="3"> <feature>Tall</feature> <feature>Wide</feature> </thing> <thing id="4"> <feature>Tall</feature> </thing> </things> Result: Wide, Thin Thanks.

  • What kind of steering behaviour or logic can I use to get mobiles to surround another?

    - by Vaughan Hilts
    I'm using path finding in my game to lead a mob to another player (to pursue them). This works to get them overtop of the player, but I want them to stop slightly before their destination (so picking the penultimate node works fine). However, when multiple mobs are pursuing the mobile they sometimes "stack on top of each other". What's the best way to avoid this? I don't want to treat the mobs as opaque and blocked (because they're not, you can walk through them) but I want the mobs to have some sense of structure. Example: Imagine that each snake guided itself to me and should surround "Setsuna". Notice how both snakes have chosen to prong me? This is not a strict requirement; even being slightly offset is okay. But they should "surround" Setsuna.

  • Logic that can traverse all possible layouts, but not checking every combination of identical pieces?

    - by George Bailey
    Suppose we have a grid of arbitrary size, which is filled by blocks of various widths and heights. There are many 2x2 blocks (meaning they take a total of 4 cells in the grid) and many 3x3 blocks, as well as some 5x4, 4x5, 2x3, etc. I was hoping I could set up a program that would look at all possible layouts, and rank them, and find the best one. Simply it would look at all possible positions of these blocks, and see what setup is the best rank. (the rank based on how many of these can be connected by a roadway system of 1x1 road blocks, and how many squares can be left empty after this is done. - wanting to fit the most blocks as possible with the least roads.) My question, is how should I traverse all the possibilities? I could take all the blocks and try them one at a time, but since all 2x2 blocks are equal, and there are a couple dozen of them, there is no point in trying every combination there, as in the following AA BBB AA BBB CCBBB CCEEE DD EEE DD EEE is exactly the same as CC EEE CC EEE AAEEE AABBB DD BBB DD BBB You notice that there are 2 3x3 blocks and 3 2x2 blocks in my two examples. Based on the model I have now, the computer would try both of these combinations, as well as many others. The problem is that it is going to try every single possible variation of my couple dozen 2x2 blocks. And that is sorely inefficient. Is there a reasonable way to take out this duplicated work, somehow getting the computer program to treat all 2x2 blocks as equal/identical, instead of one requiring rearranging/swapping of these identical blocks? Can this be done?

  • Maintainability of Boolean logic - Is nesting if statements needed?

    - by Vaccano
    Which of these is better for maintainability? if (byteArrayVariable != null) if (byteArrayVariable .Length != 0) //Do something with byteArrayVariable OR if ((byteArrayVariable != null) && (byteArrayVariable.Length != 0)) //Do something with byteArrayVariable I prefer reading and writing the second, but I recall reading in code complete that doing things like that is bad for maintainability. This is because you are relying on the language to not evaluate the second part of the if if the first part is false and not all languages do that. (The second part will throw an exception if evaluated with a null byteArrayVariable.) I don't know if that is really something to worry about or not, and I would like general feedback on the question. Thanks.

  • What is wrong with my logic for the divide and conquer algorithm for Closest pair problem?

    - by Programming Noob
    I have been following Coursera's course on Algorithms and came up with a thought about the divide/conquer algorithm for the closest pair problem, that I want clarified. As per Prof Roughgarden's algorithm (which you can see here if you're interested): For a given set of points P, of which we have two copies - sorted in X and Y direction - Px and Py, the algorithm can be given as closestPair(Px,Py): Divide points into left half - Q, and right half - R, and form sorted copies of both halves along x and y directions - Qx,Qy,Rx,Ry Let closestPair(Qx,Qy) be points p1 and q1 Let closestPair(Rx,Ry) be p2,q2 Let delta be minimum of dist(p1,q1) and dist(p2,q2) This is the unfortunate case, let p3,q3 be the closestSplitPair(Px,Py,delta) Return the best result Now, the clarification that I want is related to step 5. I should say this beforehand, that what I'm suggesting, is barely any improvement at all, but if you're still interested, read ahead. Prof R says that since the points are already sorted in X and Y directions, to find the best pair in step 5, we need to iterate over points in the strip of width 2*delta, starting from bottom to up, and in the inner loop we need only 7 comparisions. Can this be bettered to just one? How I think is possible seemed a little difficult to explain in plain text, so I drew a diagram and wrote it on paper and uploaded it here: Since no one else came up with is, I'm pretty sure there's some error in my line of thought. But I have literally been thinking about this for HOURS now, and I just HAD to post this. It's all that is in my head. Can someone point out where I'm going wrong?

  • What options are there for splitting UI layout from code logic using a markup language?

    - by Daenyth
    What tools similar to GWT's UIBinder exist in other languages? By this I mean a system where you can define your UI layout in a markup language (preferably html+css) and attach the functionality to the layout using the code. I'm most interested in anything for python, but answers in other languages would interest me as well. I'm interested because the benefits of having a non-programmer work directly on the layout without needing to touch the code and adjust a bunch of UI toolkit method calls is very productive. I'm aware of Flex for flash, but is there anything else out there? What search terms might I use to find such frameworks? I've looked around but I haven't found anything concrete.

  • Entity Framework 5, separating business logic from model - Repository?

    - by bnice7
    I am working on my first public-facing web application and I’m using MVC 4 for the presentation layer and EF 5 for the DAL. The database structure is locked, and there are moderate differences between how the user inputs data and how the database itself gets populated. I have done a ton of reading on the repository pattern (which I have never used) but most of my research is pushing me away from using it since it supposedly creates an unnecessary level of abstraction for the latest versions of EF since repositories and unit-of-work are already built-in. My initial approach is to simply create a separate set of classes for my business objects in the BLL that can act as an intermediary between my Controllers and the DAL. Here’s an example class: public class MyBuilding { public int Id { get; private set; } public string Name { get; set; } public string Notes { get; set; } private readonly Entities _context = new Entities(); // Is this thread safe? private static readonly int UserId = WebSecurity.GetCurrentUser().UserId; public IEnumerable<MyBuilding> GetList() { IEnumerable<MyBuilding> buildingList = from p in _context.BuildingInfo where p.Building.UserProfile.UserId == UserId select new MyBuilding {Id = p.BuildingId, Name = p.BuildingName, Notes = p.Building.Notes}; return buildingList; } public void Create() { var b = new Building {UserId = UserId, Notes = this.Notes}; _context.Building.Add(b); _context.SaveChanges(); // Set the building ID this.Id = b.BuildingId; // Seed 1-to-1 tables with reference the new building _context.BuildingInfo.Add(new BuildingInfo {Building = b}); _context.GeneralInfo.Add(new GeneralInfo {Building = b}); _context.LocationInfo.Add(new LocationInfo {Building = b}); _context.SaveChanges(); } public static MyBuilding Find(int id) { using (var context = new Entities()) // Is this OK to do in a static method? { var b = context.Building.FirstOrDefault(p => p.BuildingId == id && p.UserId == UserId); if (b == null) throw new Exception("Error: Building not found or user does not have access."); return new MyBuilding {Id = b.BuildingId, Name = b.BuildingInfo.BuildingName, Notes = b.Notes}; } } } My primary concern: Is the way I am instantiating my DbContext as a private property thread-safe, and is it safe to have a static method that instantiates a separate DbContext? Or am I approaching this all wrong? I am not opposed to learning up on the repository pattern if I am taking the total wrong approach here.

  • Where should a programmer explain the extended logic behind the code?

    - by SRKX
    I have developed a few quantitative libraries in C# where it is important to understand not only the classic information that goes with the XMLDoc comments (which contains basic information with the method signature) but also the mathematical formulas being use within the methods. Hence I would like to be able to include extended documentation with the code, which could contain, for example Latex formulas, graphs, and so on. Do you think such information should be included in the API documentation? Or should it be included in a dev blog for examples? Are there common tools that are usually used for this kind of purposes?

  • C# calendar needs Business Logic for real-time reminders? [on hold]

    - by lazfish
    I am not a super experienced C# user, though I have some experience in .Net and VB.Net. Just got this new job and my first assignment is a mission critical part of the business. It is pretty important I get it right so I was hoping for some sage advice. We have created a calendar using jQuery, C#, .Net & SQL Server 08. The calendar works but now we are wanting to add email, SMS and voice-call reminders. We are a small company and can do whatever we need to do with no restrictions on our IT environment. I have some base-line experience with Unix servers but would prefer to stay in the Micro$oft universe if it is prudent to do so. I know how to add the API calls and services to initiate these reminders (using built in email services for email and Twilio.com for SMS). I am asking for advice about how to approach a reliable and timely listener service that knows when to call the service or API for the reminder before an appointment. EG. SMS: "You have a conference call in 30 minutes." I have done some research, but it is hard to know what is a proven reliable approach. What I am looking for is an experienced opinion on a good (or the best) strategy for implementing a solution that will reliably listen for appointments and dispatch the reminders when needed.

  • How much business logic belongs in RIA services layer?

    - by jkohlhepp
    I have been experimenting recently with Silverlight, RIA Services, and Entity Framework using .NET 4.0. I'm trying to figure out if that stack makes sense for use in any of my upcoming projects. It certainly seems like these technologies can be very productive for developing applications, but I'm struggling to decide how an application on top of this stack should be architected. The main issue I have is that in most of the demos I've seen most of the business logic ends up as DataAnnotations and custom validations in the RIA Services domain service class. This seems inappropriate to me. I view the domain service as basically a glorified web service that happens to make it easy to push information to the client. But most of what I've seen seems to orient the domain service as the main source of business logic in the application. So, my questions: What is the best location for business logic (rules, validations, behaviors, authorization) in an application using this stack? Are there any guidelines published at an architectural level for using this stack? My questions pertain to large, complex, and long-lived applications. Obviously for an application of only a few screens this is less of a concern. Edit: Another thing I meant to mention is that obviously you can make the domain service class stupid, but then you lose a lot of the automagic entity information (e.g. validations) being pushed to the client. And then if you lose that is there any point to using RIA services?

  • Logic in the db for maintaining a points system relationship?

    - by MarcusBooster
    I'm making a little web based game and need to determine where to put logic that checks the integrity of some underlying data in the sql database. Each user keeps track of points assigned to him, and points are awarded by various tasks. I keep a record of each task transaction to make sure they're not repeated, and to keep track of the value of the task at the time of completion, since an individual award level my fluctuate over time. My schema looks like this so far: create table player ( player_ID serial primary key, player_Points int not null default 0 ); create table task ( task_ID serial primary key, task_PointsAwarded int not null ); create table task_list ( player_ID int references player(player_ID), task_ID int references task(task_ID), when_completed timestamp default current_timestamp, point_value int not null, --not fk because task value may change later constraint pk_player_task_id primary key (player_ID, task_ID) ); So, the player.player_Points should be the total of all his cumulative task points in the task_list. Now where do I put the logic to enforce this? Should I do away with player.player_Points altogether and do queries every time I want to know the total score? Which seems wasteful since I'll be doing that query a lot over the course of a game. Or, put a trigger in the task_list that automatically updates the player.player_Points? Is that too much logic to have in the database and should just maintain this relationship in the application? Thanks.

  • Should the program logic reside inside the gui object class or be external to the class?

    - by hd112
    I have a question about how to structure code in relation to GUI objects. Suppose I have a dialog that has a list control that has a bunch of names obtained from a database. The user can edit the names. Does the logic reside inside that dialog class or should it be from the outside. To illustrate what I mean, here’s some pseudo code showing the structure of the code when the logic is handled outside the dialog class: NamesDialog : wxDialog { Private: ..stuff.. Public: ... SetNames(wxStringArray names); wxStringArray GetNames(); ..stuff.. } So the user of the class would do something like: wxStringArray names = DatabaseManager::Get()->GetNames(); names.Sort(); NamesDialogObject.SetNames(names); NamesDialogObject.ShowModal(); wxStringArray modified_names = NamesDialogObject.GetNames(); AddToDatabase(modified_names); //or something like this. On the other hand, the database logic can reside inside the NamesDialog class itself. In the show method I can query the database for the names and as the user interacts with the controls (list control in this case), the database can be updated from the event handlers. As a result the NamesDialog class only has the Show() method as there is no need to use SetNames or GetNames() etc. Which method is generally preferred? I don’t have much work experience so I’m not sure which is the proper way to handle it. Sometimes it's easier to handle everything in the class but getting access to objects it interacts with can be challenging. Generally can do it by having the relevant objects be singletons like the database manager in the above example.

  • What is the logic behind IE7s Ctrl-Tab order?

    - by torbengb
    Using Ctrl+Tab in Internet Explorer 7 (on Windows XP) seems to follow no sequence that I can work out. Using Shift+Ctrl+Tab even jumps around with no clear logic in what tab order is being followed. It doesn't even work to the reverse as expected from using it in other programs, such as Firefox. Please explain to me how this key combo works in IE7 because I can't figure it out.

  • How do I refactor these two C# functions to abstrtact their logic from the specific class properties

    - by ObligatoryMoniker
    I have two functions whose underlying logic is the same but in one case it sets one property value on a class and in another case it sets a different one. How can I rewrite the following two functions to abstract away as much of the algorithm as possible so that I can make changes in logic in a single place? SetBillingAddress private void SetBillingAddress(OrderAddress newBillingAddress) { BasketHelper basketHelper = new BasketHelper(SiteConstants.BasketName); OrderAddress oldBillingAddress = basketHelper.Basket.Addresses[basketHelper.BillingAddressID]; bool NewBillingAddressIsNotOldBillingAddress = ((oldBillingAddress == null) || (newBillingAddress.OrderAddressId != oldBillingAddress.OrderAddressId)); bool BillingAddressHasBeenPreviouslySet = (oldBillingAddress != null); bool BillingAddressIsNotSameAsShippingAddress = (basketHelper.ShippingAddressID != basketHelper.BillingAddressID); bool NewBillingAddressIsNotShippingAddress = (newBillingAddress.OrderAddressId != basketHelper.ShippingAddressID); if (NewBillingAddressIsNotOldBillingAddress && BillingAddressHasBeenPreviouslySet && BillingAddressIsNotSameAsShippingAddress) { basketHelper.Basket.Addresses.Remove(oldBillingAddress); } if (NewBillingAddressIsNotOldBillingAddress && NewBillingAddressIsNotShippingAddress) { basketHelper.Basket.Addresses.Add(newBillingAddress); } basketHelper.BillingAddressID = newBillingAddress.OrderAddressId; basketHelper.Basket.Save(); } And here is the second one: SetShippingAddress private void SetBillingAddress(OrderAddress newShippingAddress) { BasketHelper basketHelper = new BasketHelper(SiteConstants.BasketName); OrderAddress oldShippingAddress = basketHelper.Basket.Addresses[basketHelper.ShippingAddressID]; bool NewShippingAddressIsNotOldShippingAddress = ((oldShippingAddress == null) || (newShippingAddress.OrderAddressId != oldShippingAddress.OrderAddressId)); bool ShippingAddressHasBeenPreviouslySet = (oldShippingAddress != null); bool ShippingAddressIsNotSameAsBillingAddress = (basketHelper.ShippingAddressID != basketHelper.BillingAddressID); bool NewShippingAddressIsNotBillingAddress = (newShippingAddress.OrderAddressId != basketHelper.BillingAddressID); if (NewShippingAddressIsNotOldShippingAddress && ShippingAddressHasBeenPreviouslySet && ShippingAddressIsNotSameAsBillingAddress) { basketHelper.Basket.Addresses.Remove(oldShippingAddress); } if (NewShippingAddressIsNotOldShippingAddress && NewShippingAddressIsNotBillingAddress) { basketHelper.Basket.Addresses.Add(newShippingAddress); } basketHelper.ShippingAddressID = newShippingAddress.OrderAddressId; basketHelper.Basket.Save(); } My initial thought was that if I could pass a class's property by refernce then I could rewrite the previous functions into something like private void SetPurchaseOrderAddress(OrderAddress newAddress, ref String CurrentChangingAddressIDProperty) and then call this function and pass in either basketHelper.BillingAddressID or basketHelper.ShippingAddressID as CurrentChangingAddressIDProperty but since I can't pass C# properties by reference I am not sure what to do with this code to be able to reuse the logic in both places.

  • How to structure an enterprise MVC app, and where does Business Logic go?

    - by James
    I am an MVC newbie. As far as I can tell: Controller: deals with routing requests View: deals with presentation of data Model: looks a whole lot like a Data Access layer Where does the Business Logic go? Take a large enterprise application with: Several different sources of data (WCF, WebServices and ADO) tied together in a data access layer (useing multiple different DTOs). A lot business logic segmented over several dlls. What is an appropriate way for an MVC web application to sit on top of this (in terms of code and project structure)? The example I have seen where everything just goes in the Model folder don't seem like they are appropriate for very large applications. Thanks for any advice!

  • If you are forced to use an Anemic domain model, where do you put your business logic and calculated

    - by Jess
    Our current O/RM tool does not really allow for rich domain models, so we are forced to utilize anemic (DTO) entities everywhere. This has worked fine, but I continue to struggle with where to put basic object-based business logic and calculated fields. Current layers: Presentation Service Repository Data/Entity Our repository layer has most of the basic fetch/validate/save logic, although the service layer does a lot of the more complex validation & saving (since save operations also do logging, checking of permissions, etc). The problem is where to put code like this: Decimal CalculateTotal(LineItemEntity li) { return li.Quantity * li.Price; } or Decimal CalculateOrderTotal(OrderEntity order) { Decimal orderTotal = 0; foreach (LineItemEntity li in order.LineItems) { orderTotal += CalculateTotal(li); } return orderTotal; } Any thoughts?

  • How to reuse backup on Time Machine on Snow Leopard after a logic board change, after choosing wrong

How can I trigger that popup again? Turning Time Machine on and off does not work, and the instructions on forums to fix via terminal doesn't work because snow leopard is missing the fsaclctl command (and I'm also not familiar with terminal commands.)
