• Image an entire computer

  - by DalexL

  I want to start doing a computer repair. I know that some issues may arise (what if I do something wrong and ruin the entire computer?). I'm not saying I'm not confident in my work, but accidents do happen sometimes. Now, the best solution this problem would be to simply just backup their entire computer and restore it if anything goes wrong. If I have an external HD, are there any available methods to create an entire image for the computer so no matter what I do, I can just reload it's last state?

• Can't start computer, it only boots into BIOS update

  - by kerry

  My son has a Compaq Presario computer running on Windows 7 and he has brought it down to me cause it's 'not working'. When I start up the computer I get a HP BIOS update that fails and keeps restarting with the same screens, only to fail every time. I have read some forum posts that suggest taking it back to default settings – how do I do this when I cant get anything on the computer screen except for the update? I'm a complete novice with computers.

• Minimum rights to access the whole Users directory on another computer

  - by philipthegreat

  What is the minimum rights required to access the Users directory on another computer via an admin share? I have a batch file that writes some information to a few other computers using a path of \\%COMPUTERNAME%\c$\Users\%USERNAME%\AppData\Roaming. The batch files run under an unprivileged user (part of Domain Users only). How do I set appropriate rights so that service account can access the AppData\Roaming folder for every user on another computer? I'd like to give rights lower than Local Admin, which I know will work. Things I've attempted: As Domain Admin, attempted to give Modify rights to the C:\Users\ directory on the local computer. Error: Access Denied. Set the service account as Local Admin on the other computer. This works, but is against IT policy where I work. I'd like to accomplish this with rights lower than Local Admin. Any suggestions?

• X11 not sending windows to remote computer matlab

  - by MZimmerman6

  I am trying to set up my home desktop, running OS X Mountain Lion, to basically do a bunch of grunt work for me remotely. I have set up ssh, and am able to remotely control the computer fine, but the issue comes in when I try to run X11 apps, like MATLAB, remotely and get windows to pop up. Every time I try to bring up a new window it either opens that window on the remote computer (not the one I am using to control it), or it tells me it can't find a display. here is how I am setting up my ssh assume my matlab alias is set up properly, which it is. ssh -X [email protected] matlab -nodesktop figure; This will open the window on the computer I am SSHing into, and not on the remote one. Basically I want that window to open on the computer I am remoting from. I changed my SSH X11Forwarding and stuff to be yes in ssh_config and sshd_config. Any other suggestions?

• Stream computer screen to TV via network instead of a USB wireless link

  - by user24559

  I want to stream my computer screen (not just video or a limited amount of content) to my TV via the network. I know there are wireless devices that use USB to tranfer the screen to the TV. However, these are limited to a short distance. What I want to do is stream the data via the network so I can be anywhere within the network and have the data shown on the tv. I am looking for video and sound to transfer. I want the entire computer screen to transfer just like when you connect the computer to the tv via VGA or HDMI and the sound out using the 3.5mm plug. I have been unable to find a unit that allows for the entire computer screen to transfer via the network. I just find the ability to stream video. I am using Windows 7 Ultimate with a quad processor and 16 GB of memory so I have the power to handle the transfer. My tv is hdtv.

• Windows 7 : access denied to ONE server from ONE computer

  - by Gregory MOUSSAT

  We have a domain served by some Windows 2003 servers. We have several Windows 7 Pro clients. ONE client computer can't acces ONE member Windows 2003 server. The other computers can acces every servers. And the same computer can access other servers. With explorer, the message says the account is no activated. With the command line, the message says the account is locked. With commande line : net use X: \\server\share --> several seconds delay, then error (says the account is locked) net use X: \\server\share /USER:current_username --> okay net use X: \\server\share /USER:domain_name\current_username --> okay From the same computer, the user can access other servers. From another computer, the same user can access any server, including the one denied from the original computer. Aleady done : unjoin then join the cilent from the domain. check the logs on the server : nothing about the failed attempts (?!) Is their any user mapping I'm not aware of ?

• Computer won't start when connecting SATA HDD

  - by vlad

  I just bough a new HDD some time ago and recently i bought another SATA cable to have both HDDs connected at the same time, to transfer all the files from the older one to the newer. When i connected both of them, the computer started working, i tapped F2 to go to bios to make sure it was detected, and then after 5-10 seconds the computer instantly shut down. After this incident, my computer won't start at all when connecting the SATA power supply to the old HDD. If i connect only my new drive, it works without any problem. If i connect only my old drive, or both the old drive and the new one, and then push on the power button, the cpu fan simply rotates about 5 degrees and then stops.. and that's it, the computer doesn't start, and no sound from the pc speaker either. Is there any way to recover my files from the old HDD and transfer them to my new one? I do not want to use the old HDD any more, i only need to save all my files.

• Choosing the right .NET architecture. WCF? WPF/Forms, ASP.NET (MVC)?

  - by Tommy Jakobsen

  I’m in the situation that I have to design and implement a rather big system from the bottom. I’m having some (a lot actually) questions about the architecture that I would like your comments and thoughts on. I don’t hope that I’ve written too much here, but I wanted to give you all an idea of what the system is. Quick info about the applications, read if you want: I can’t share much detail about the project, but basically it’s a system where we offer our customer a service to manage their users. We have a hotline where the users call and our hotline uses an (windows) application (intranet) to manage the user’s data, etc. The customer also has a web application where they can see reports, information about their business and users, and the ability to modify their data. Modifying data is not just user data like address and so, but also information about the products/services the user has, which can be complicated. The applications will be built on Microsoft .NET Framework 4, with a MS SQL Server 2008 database. There will be a few applications that have to access this database, such as: Intranet application (used by us and our hotline) Customer web application type 1 Customer web application type 2 Customer web application type n different applications) … Now my big problem is what .NET parts I should use for such a system. For the “backend” I’ve considered using Windows Communication Foundation: Would WCF be a good choice? The intranet application will be an application that has to edit lots of records in the database. It has to be easy to navigate using the keyboard (fast to work with). Has a feature such as “find customer, find that, lookup this, choose this and update that”. What would be the best choice to develop this application in? Would it be WPF or good old Windows Forms? I don’t need all of the fancy graphics features in WPF, like 3D, but the application has to look nice (maybe something like the new Visual Studio/Office tools). And the same question goes for the web pages. They have much the same work to do, but not as many features as the intranet application, and not the same amount of data (much less). That is my questions for now. I’m hoping to get a discussion going that will open my eyes to some of these technologies, helping me decide architecture to go with. I would like to say thanks in advance, and let you all know that any thoughts will be much appreciated.

• How to train yourself to avoid writing “clever” code?

  - by Dan Abramov

  Do you know that feeling when you just need to show off that new trick with Expressions or generalize three different procedures? This does not have to be on Architecture Astronaut scale and in fact may be helpful but I can't help but notice someone else would implement the same class or package in a more clear, straightforward (and sometimes boring) manner. I noticed I often design programs by oversolving the problem, sometimes deliberately and sometimes out of boredom. In either case, I usually honestly believe my solution is crystal clear and elegant, until I see evidence to the contrary but it's usually too late. There is also a part of me that prefers undocumented assumptions to code duplication, and cleverness to simplicity. What can I do to resist the urge to write “cleverish” code and when should the bell ring that I am Doing It Wrong? The problem is getting even more pushing as I'm now working with a team of experienced developers, and sometimes my attempts at writing smart code seem foolish even to myself after time dispels the illusion of elegance.

• AIA und die "IT Strategies from Oracle"

  - by Hans Viehmann

  Die Oracle Application Integration Architecture lässt sich gut nutzen, um eine SOA Initiative zügig zu starten. Naturgemäß berücksichtigt sie aber nicht alle Aspekte einer IT Strategie. Zu diesem Thema gibt es nun seit einigen Wochen eine umfassende Bibliothek von Handbüchern ("Practitioner's Guides") und Referenz-Architekturen, in denen die Erfahrung aus zahlreichen Projekten zusammengefasst ist.Hier ist beispielsweise ein IT Governance Framework beschrieben, das auch die wesentlichen Aspekte der SOA GovernanceSOA Portfolio GovernanceService Lifecycle GovernanceSOA Solution Lifecycle GovernanceSOA Vitality GovernanceSOA Organization Governancenäher beschreibt.In den Handbüchern sind zahlreiche wertvolle Hinweise und best practices enthalten; ich denke, es lohnt sich, einen Blick hinein zu werfen.Die gesamte Bibliothek findet sich unter http://www.oracle.com/goto/itstrategies; eine Übersicht über die verschiedenen Aspekte ist in dem Bild unten zusammengefasst.View image

• Amazon SOA: database as a Service

  - by Martin Lee

  There is an interesting interview with Werner Vogels which is partly about how Amazon does Service Oriented Architecture: For us service orientation means encapsulating the data with the business logic that operates on the data, with the only access through a published service interface. No direct database access is allowed from outside the service, and there’s no data sharing among the services. I do not understand that. Why do they need to 'wrap' a database into some layer if it already can be consumed as a service by other service through database adaptors? Does Amazon do that just because they need to expose the database to third parties or because of anything else? Why "no direct database access is allowed"? What are the advantages of such an architectural decision?

• Can a loosely typed language be considered true object oriented?

  - by user61852

  Can a loosely typed programming language like PHP be really considered object oriented? I mean, the methods don't have returning types and method parameters has no declared type either. Doesn't class design require methods to have a return type? Don't methods signatures have specifically-typed parameters? How can OOP techniques help you code in PHP if you always have to check the types of parameters received because the language doesn't enforce types? Please, if I'm wrong, explain it to me. When you design things using UML, then code classes in PHP with no return-typed methods and no-type parameters... Is the code really compliant with the UML design? You spend time designing the architecture of your software, then the compiler doesn't force the programmer to follow your design while coding, letting he/she assign any object variable to any other variable with no "type-mismatch" warning.

• Developing an analytics's system processing large amounts of data - where to start

  - by Ryan

  Imagine you're writing some sort of Web Analytics system - you're recording raw page hits along with some extra things like tagging cookies etc and then producing stats such as Which pages got most traffic over a time period Which referers sent most traffic Goals completed (goal being a view of a particular page) And more advanced things like which referers sent the most number of vistors who later hit a goal. The naieve way of approaching this would be to throw it in a relational database and run queries over it - but that won't scale. You could pre-calculate everything (have a queue of incoming 'hits' and use to update report tables) - but what if you later change a goal - how could you efficiently re-calculate just the data that would be effected. Obviously this has been done before ;) so any tips on where to start, methods & examples, architecture, technologies etc.

• How should modules access data outside their scope?

  - by Joe

  I run into this same problem quite often. First, I create a namespace and then add modules to this namespace. Then issue I always run into is how best to initialize the application? Naturally, each module has its own startup procedure so should this data(not code in some cases, just a list of items to run) stay with the module? Or should there be a startup procedure in the global namespace which has the startup data for ALL the modules. Which is the more robust way of organizing this situation? Should some things be made centralized or should there be strict adherence to modules encapsulating everything about themselves? Though this is a general architecture questions, Javascript centric answers would be really appreciated!

• Looking for literature about graphics pipeline optimization

  - by zacharmarz

  I am looking for some books, articles or tutorials about graphics architecture and graphics pipeline optimizations. It shouldn't be too old (2008 or newer) - the newer, the better. I have found something in [Optimising the Graphics Pipeline, NVIDIA, Koji Ashida] - too old, [Real-time rendering, Akenine Moller], [OpenGL Bindless Extensions, NVIDIA, Jeff Bolz], [Efficient multifragment effects on graphics processing units, Louis Frederic Bavoil] and some internet discussions. But there is not too much information and I want to read more. It should contain something about application, driver, memory and shader units communication and data transfers. About vertices and attributes. Also pre and post T&L cache (if they still exist in nowadays architectures) etc. I don't need anything about textures, frame buffers and rasterization. It can also be about OpenGL (not about DirecX) and optimizing extensions (not old extensions like VBOs, but newer like vertex_buffer_unified_memory).

• What can programmers learn from the construction industry?

  - by Renesis

  When talking with colleagues about software design and development principles, I've noticed one of the most common sources for analogies is the construction industry. We build software and we consider the design and structure to be the architecture. One of the best ways to learn (or teach) are through analyzing analogies - what other analogies can be drawn from construction? (whether already in common use in software or not). Please provide a description, or your personal experience, regarding how the programming concept is similar to the construction concept. [Credit to Programming concepts taken from the arts and humanities for the idea]

• Application layer vs domain layer?

  - by Louis Rhys

  I am reading Domain-Driven Design by Evans and I am at the part discussing the layered architecture. I just realized that application and domain layers are different and should be separate. In the project I am working on, they are kind of blended and I can't tell the difference until I read the book (and I can't say it's very clear to me now), really. My questions, since both of them concerns the logic of the application and are supposed to be clean of technical and presentation aspects, what are the advantages of drawing a boundary these two?

• Convenient practice for where to place images?

  - by Baumr

  A lot of developers place all image files inside a central directory, for example: /i/img/ /images/ /img/ Isn't it better (e.g. content architecture, on-page SEO, code maintainability, filename maintainability, etc.) to place them inside the relevant directories in which they are used? For example: example.com/logo.jpg example.com/about/photo-of-me.jpg example.com/contact/map.png example.com/products/category1-square.png example.com/products/category2-square.png example.com/products/category1/product1-thumb.jpg example.com/products/category1/product2-thumb.jpg example.com/products/category1/product1/product1-large.jpg example.com/products/category1/product1/product2-large.jpg example.com/products/category1/product1/product3-large.jpg What is the best practice here regarding all possible considerations (for static non-CMS websites)? N.B. The names product1-large and product1-thumb are just examples in this context to illustrate what kind of images they are. It is advised to use descriptive filenames for SEO benefit.

• Understanding Data Binding for Windows Phone 7

  - by nikhil

  I want to develop a simple app for the Windows Phone 7 platform. It's basically a vocabulary based game that involves the user moving word tiles from one area to another to score points. I want to know what is the best way of tying the UI to the game's backend? I saw the Windows Phone 7 jumpstart videos, there they touch up on Data Binding but don't really go into any depth. I'm a newbie and don't have any experience with designing the architecture for a phone app, It'd be great if someone could explain what steps I should be taking or guide me to a resource from where I could learn more.

• HTML Canvas: Should my app x, y values be global?

  - by Joe

  I have a large file of functions. Each of these functions is responsible for drawing a particular part of the application. My app has x and y parameters that I use in the setup function to move the whole app around in order to try different placements. So, naturally, I need to use these x and y values to anchor each function's component rendering so that everything moves in unison if the global x,y values ever change. My question is, is it bad practice/architecture to have these x,y values in the global namespace and having the each function directly access them like so? function renderFace() { var x = App.x; var y = App.y; // drawing here } is there a better way i'm missing?

• Material, Pass, Technique and shaders

  - by Papi75

  I'm trying to make a clean and advanced Material class for the rendering of my game, here is my architecture: class Material { void sendToShader() { program->sendUniform( nameInShader, valueInMaterialOrOther ); } private: Blend blendmode; ///< Alpha, Add, Multiply, … Color ambient; Color diffuse; Color specular; DrawingMode drawingMode; // Line Triangles, … Program* program; std::map<string, TexturePacket> textures; // List of textures with TexturePacket = { Texture*, vec2 offset, vec2 scale} }; How can I handle the link between the Shader and the Material? (sendToShader method) If the user want to send additionals informations to the shader (like time elapsed), how can I allow that? (User can't edit Material class) Thanks!
