  • Some good websites to learn about JavaScript and programming architecture?

    - by Jack Roscoe
    I'm not sure if 'architecture' is the correct term, but I've been looking for some articles online which talk about programming design and more about how best to use languages such as JavaScript in a code design sense rather than the actual syntax itself. I have found many websites but a lot seem to be very out dated, and I'm not sure what developments have taken place with JavaScript over the years so do not know how old is too old. If anybody could suggest some great websites, or maybe specific articles you think would be useful, that would be highly appreciated. I am a beginner programmer currently using JavaScript with XML and of course HTML & CSS, and I'm currently trying to get further into and learn more about web development.

  • A good architecture is evil? Hardcode forever?

    - by igor
    I have worked in many companies. Most of all reached a big success in their field. Some times I found the code was written by owner or co-owner or the first developer of this company. It was strange from architectural point of view code or awful code styled, or hardcoded and so on. I know a couple of startups, that were grown up and were started from the "one night" code. Is it only way to get success to write code in this way? Why does a code written "on knee" but in time is better than delayed well thought-out one? What about future? Which way is the best: to write a good architecture, code and spend some more time at the startup or to write "fast" and hardcoded one that would be completely (partially) throw out (or maybe wouldn't) after some period of time (or never)?

  • Unable to connect to Samba printer

    - by user127236
    I have a headless Ubuntu 12.04 server for files and printers. It shares files via Samba just fine. However, the HP PSC-750xi connected to the server via USB is not accessible from my Ubuntu 12.04 laptop. I can browse for it in the Printing control panel, but any attempt to authenticate my ID to the printer with my user credentials results in the error "This print share is not accessible". I have included the Samba smb.conf file below. Any help appreciated. Thanks... JGB # # Sample configuration file for the Samba suite for Debian GNU/Linux. # # # This is the main Samba configuration file. You should read the # smb.conf(5) manual page in order to understand the options listed # here. Samba has a huge number of configurable options most of which # are not shown in this example # # Some options that are often worth tuning have been included as # commented-out examples in this file. # - When such options are commented with ";", the proposed setting # differs from the default Samba behaviour # - When commented with "#", the proposed setting is the default # behaviour of Samba but the option is considered important # enough to be mentioned here # # NOTE: Whenever you modify this file you should run the command # "testparm" to check that you have not made any basic syntactic # errors. # A well-established practice is to name the original file # "smb.conf.master" and create the "real" config file with # testparm -s smb.conf.master >smb.conf # This minimizes the size of the really used smb.conf file # which, according to the Samba Team, impacts performance # However, use this with caution if your smb.conf file contains nested # "include" statements.

  • Connect to host computer from Virtual PC 2007

    - by Vegard Larsen
    I am having trouble using my guest (Windows XP SP3) to communicate over TCP/IP to the host computer (Windows 7) using Virtual PC 2007. I have WAMPServer running on my host, and want to be able to access the websites on there from my guest OS. What do I do to make this work? What is the IP address of the host computer when using Shared Networking? As far as I can tell "Internal Networking" won't work, because that only allows communication between the guests, not between a guest and the host.

  • vmware windows7 professional changing ip addresses

    - by chris hough
    is there a way to fix your windows 7 professional guest host os ipaddress so it does not change every time you startup? I am currently using NAT for networking and would like to remain using this networking method if possible. In older versions of windows this never used to be a problem in vmware so I am wondering if I am missing a setting in windows 7 professional or in vmware. thank you for your help, chris

  • Cannot reset an network interfaces without a reboot

    - by yangchenyun
    I have edited the /etc/network/interfaces file and I use the sudo /etc/init.d/networking restart. After restart, the eth1 interfaces don't setup properly. I need a hard reboot to enable this configuration. Meanwhile the command line hints: Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces. Am I using the run command to restart network interfaces? auto eth1 iface eth1 inet static address 192.168.1.87 netmask 255.255.255.0 gateway 192.168.1.1

  • JavaOne - Java SE Embedded Booth - Servergy Micro Server

    - by David Clack
    Hi All,  So it's been awhile, I've been working with all the ARM and Power Architecture partners we have now on testing Java SE Embedded. We will have a Java SE Embedded for ARM and PPC at Java One next week, I'll be bringing in some of the great ARM and PPC systems to demonstrate.  The first system I'd like to tell you about is a really cool 8 core Power Architecture Micro Server from a company in Dallas called Servergy. Java One will be it's first public outing, Bill Mapp the CEO will be doing a talk at the Java Embedded @ JavaOne conference in the Hotel Nikko, right next door to the JavaOne show in the Hilton. To read more about Servergy https://www.linux.com/news/enterprise/cloud-computing/641488-linux-based-servergy-advances-data-center-efficiency http://www.servergy.com/ If you are registered at JavaOne you can come over to the Java Embedded @ JavaOne for $100 Come see us in booth 5605 See you there Dave

  • Getting out of my head

    - by BenCole
    (I put this on SO, but it got a couple close votes saying it belonged here instead...) I've spent the last year as a single person team developing a rich-client application (35,000+ LoC, for what it's worth). It's currently stable and in production. However, I know that my skills were rusty at the beginning of the project, so without a doubt there are major issues to the code. At this point, most of the issues are in architecture, structure, or interactions - the easy problems, even architecture/design problems, have already been weeded out. Unfortunately, I've spent so much time with this project that I'm having a hard time thinking outside of it - approaching it from a new perspective to see the flaws deeply buried or inherent in the design. How do I step outside my head and outside my code so I can get a fresh look at this code so I can make it better? Is this less of an issue than I think it is, or is this a problem for other people as well?

  • Good floor planner program?

    - by torbengb
    I'm planning to have a house built. I want to draw up some sketches on the computer, so I am looking for a program that can help me do this. It doesn't have to be a professional architecture tool; in fact that would be too complicated just yet (but maybe later on, for the detailed work...?). A simpler tool would be better. Features should include such things as ability to draw and move walls (not just using simple boxes), calculate room/floor area, add windows and doors, and the like. That's why Inkscape or OOo Presentation won't do. On Windows, a friend would just download a cracked professional architecture tool but that is not what I want to do. Suggestions?

  • Interview question: How would you implement Google Search?

    - by ripper234
    Supposed you were asked in an interview "How would you implement Google Search?" How would you answer such a question? There might be resources out there that explain how some pieces in Google are implemented (BigTable, MapReduce, PageRank, ...), but that doesn't exactly fit in an interview. What overall architecture would you use, and how would you explain this in a 15-30 minute time span? I would start with explaining how to build a search engine that handles ~ 100k documents, then expand this via sharding to around 50M docs, then perhaps another architectural/technical leap. This is the 20,000 feet view. What I'd like is the details - how you would actually answer that in an interview. Which data structures would you use. What services/machines is your architecture composed of. What would a typical query latency be? What about failover / split brain issues? Etc...

  • How and what setting do you use in order to create your customized application with database? [closed]

    - by FullmetalBoy
    I have a homemade project combining with application and database. Today I'm using architecture N-tier. Totally I have 4 project in my solution in VS2010. The fourth project is a transaction layer that connect all the 3 project (one for presentation, business logic and database layer) in order to retrieve data from the database and all the way to present the data in presentation layer. Transaction layer contains entity framework 4 + customized class to carry data to the presentation layer. I always use LINQ to retrieve data in database layer. From my experience, everytime I use LINQ in relation with entity framework it always take a lot of time to retrieve data because what I believe is that my entity framework always has to reload everytime when I want to retrieve any data from the database. My question for you guys is: When you create your application connecting to a database, what architecture do you use? How do you retrieve the data from you application? Is it entity framework etc?

  • Is ROA a specific form of doing SOA?

    - by JohnDoDo
    I have read somewhere that ROA (Resource Oriented Architecture) is SOA (Service Oriented Architecture) with specific constraints added. SOA is the abstract concept of combining discrete pieces of software and ROA is an implementation of SOA with all of the constraints of RESTful services applied to it: SOA = the concept ROA = the concept + specific implementation details I also had my share of posts saying that ROA is different than SOA, then simply fallback to statements like "ROA is REST" and "SOA is SOAP" and presenting the same more or less pertinent comparisons and differences between SOAP and REST. So just to clear up my confusion: Is ROA a specific form of doing SOA?

  • Need some clarification on the ANSI/SPARC 3-tier database architecture.

    - by Moonshield
    Hi there, I'm currently revising for a databases exam and looking over some past papers, but there's one question that I'm slightly unsure about and was wondering if someone could offer some assistance. "Describe EACH of the THREE levels of the ANSI SPARC 3 level architecture. Your answer should include the purpose of EACH of the schemas, the level of abstraction they provide and the software tools that would be used to access and support them." As I understand it (although please correct me if I'm wrong): the internal schema specifies the physical storage of the data; the conceptual schema specifies the structure of the database and the domains; and the external schemas are how the database is viewed by "users" (applications, etc.). As for the abstraction, I understand that the conceptual layer means that the physical data storage can be altered without the end user being affected, likewise the The bit that I'm not sure about is what tools are used to access and support each layer. Would the internal schema be handled by the DBMS, the conceptual schema handled by some sort of DDL interpreter and the external schema handled by a DML interpreter (or have I misunderstood what each level does)? Any assistance would be greatly appreciated. Thanks, Moonshield

  • architecture - centraled location for different modules (cms, webapplications, ...) - best practise

    - by NicoJuicy
    Let's just say that i want to create a cms + other online applications. I want them all to integrate into a central location, but they also have to be available seperately (not everyone want's more than the cms solution). Would i create a huge central application that contains all the database, which communicates through a webserice with the "standalone - integrated" modules? Or would i create them seperately and the only thing that the "central" application would do is syncing the information (eg. the cms and another solution can have the same tables (eg. clients or employees). Or do you have another idea? (i know i'm a little vague, but i can't "give" a lot of details because of work - contract). If someone has all the "packages" it should be possible for the central application to integrate all the modules at one place! Or if someone has more than 1 module, it should combine this on the website. What i thought is best, is that the central location contains only the users and their rights (eg. cms - all rights, ...), and the information get synced with every change. (module cms, adding a new client - store locally and send data to the central location, central location - send to modules = table clients updated everywhere) This way it is easy if someone only "bought" a module, they can sync it easily through the complete architecture. I hope i made myself clear!

  • Do you know about the Visual Studio 2010 Architecture Guidance?

    - by Martin Hinshelwood
    If you have not seen the Visual Studio 2010 Architectural Guidance from the Visual Studio ALM Rangers then you are missing out. I have been spelunking the TFS Guidance recently and I discovered the Visual Studio 2010 Architectural Guidance. This is not an in-depth look at the capabilities of the architectural tools that shipped with Visual Studio 2010 Ultimate, but is instead a set of samples that lead you by example through real world scenarios. There is practical guidance and checklists to help guide lead developers and architects through the common challenges in understanding both existing and new applications. The content concentrates on practical guidance for Visual Studio 2010 Ultimate and is focused on modelling tools. There is integration into Visual Studio so all you need to do to access it is select “Architecture | Visual Studio ALM Rangers – Architecture Guidance”. Figure: Accessing the Architecture guidance is easy This brings up an inline version of the documentation and a kind of Explorer that lets you pick the tasks you want to perform and takes you strait to that part of the Guidance. Figure: Access the Guidance from right within Visual Studio 2010 This is a big help when you just want to figure out how to do something and can’t be bothered searching for and through the content in the provided Word documents. The Question and Answer section is full of useful content and there are six Hands-On-Labs to sink your teeth into: Creating extensions with the feature extension Explore an Existing System Scenario Extensibility Layer Diagrams New Solution Scenario Reusable Architecture Scenario Validation an Architecture Scenario I’m sold! Where can i get my hands on this fantastic content? Download the Visual Studio 2010 Architecture Tooling Guidance and if you like it don’t forget to add a review to make the team that put it together in their spare time feel all the mere loved.

  • Windows.Networking.EndpointPair constructor parameters

    - by ComFreek
    I want to create a new EndpointPair object: // hostname is a string // port is an integer var endpointPair = new Windows.Networking.EndpointPair(null, null, hostname, port); But I always get this error: 0x800a000d - JavaScript runtime error: Type mismatch I've already tried the following: converting port to a string passing "" instead of null for the first two Parameters. (null should be okay if the documentation here, under the section Remarks, is right) passing no Parameters, but that ends up in an "too few parameters" error message Above all, the documentation about the constructor has been removed (as of September 4, 2012): http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.endpointpair.endpointpair.aspx

  • No Homegroup Computers, Network Troubleshooter Fails

    - by Mokubai
    I have a problem with my Windows 7 Homegroup, between two Windows 7 Home Premium machines. On one machine I get this: The other machine in the Homegroup is perfectly happy and is able to see and browse this faulty machine as if there is nothing wrong. The Network and Sharing Center shows that I am joined to a Homegroup on my "Home" network and nothing is out of the ordinary. I have tried leaving the Homegroup and rejoining/recreating it several times and that does nothing at all. Normal browsing to machine names and looking through folders seems to work, but it's a much more clunky way to get stuff compared to the convenience of the Homegroup facilities. Starting the troubleshooter detects some problems with a "Peer Networking" (PNRpr or something like that) service not starting but fails to fix anything. Sure enough when I go to view the services via Control Panel - Administrative Tools - Services I see that both the "Peer Name Resolution Protocol" and "Peer Networking Grouping" services are stopped. Attempting to start the "Peer Networking Grouping" gives an error that a dependency service will not start, the only service it is dependant on is the "Peer Name Resolution Protocol" so I try to start that and I get an error saying that the "service could not start due to error 0x80630801" This has happened before and I have fixed it then by using System Restore and restoring the machine to a week before when I knew it had all worked. This time though I cannot remember when I last used the Homegroup from this machine and I've installed quite a bit so I don't want to go fumbling through restore points trying to find one that works... Can anyone tell me if there is a way to reset things so that this machine is able to use the Homegroup again?

  • S#harp architecture mapping many to many and ado.net data services: A single resource was expected f

    - by Leg10n
    Hi, I'm developing an application that reads data from a SQL server database (migrated from a legacy DB) with nHibernate and s#arp architecture through ADO.NET Data services. I'm trying to map a many-to-many relationship. I have a Error class: public class Error { public virtual int ERROR_ID { get; set; } public virtual string ERROR_CODE { get; set; } public virtual string DESCRIPTION { get; set; } public virtual IList<ErrorGroup> GROUPS { get; protected set; } } And then I have the error group class: public class ErrorGroup { public virtual int ERROR_GROUP_ID {get; set;} public virtual string ERROR_GROUP_NAME { get; set; } public virtual string DESCRIPTION { get; set; } public virtual IList<Error> ERRORS { get; protected set; } } And the overrides: public class ErrorGroupOverride : IAutoMappingOverride<ErrorGroup> { public void Override(AutoMapping<ErrorGroup> mapping) { mapping.Table("ERROR_GROUP"); mapping.Id(x => x.ERROR_GROUP_ID, "ERROR_GROUP_ID"); mapping.IgnoreProperty(x => x.Id); mapping.HasManyToMany<Error>(x => x.Error) .Table("ERROR_GROUP_LINK") .ParentKeyColumn("ERROR_GROUP_ID") .ChildKeyColumn("ERROR_ID").Inverse().AsBag(); } } public class ErrorOverride : IAutoMappingOverride<Error> { public void Override(AutoMapping<Error> mapping) { mapping.Table("ERROR"); mapping.Id(x => x.ERROR_ID, "ERROR_ID"); mapping.IgnoreProperty(x => x.Id); mapping.HasManyToMany<ErrorGroup>(x => x.GROUPS) .Table("ERROR_GROUP_LINK") .ParentKeyColumn("ERROR_ID") .ChildKeyColumn("ERROR_GROUP_ID").AsBag(); } } When I view the Data service in the browser like: http://localhost:1905/DataService.svc/Errors it shows the list of errors with no problems, and using it like http://localhost:1905/DataService.svc/Errors(123) works too. The Problem When I want to see the Errors in a group or the groups form an error, like: "http://localhost:1905/DataService.svc/Errors(123)?$expand=GROUPS" I get the XML Document, but the browser says: The XML page cannot be displayed Cannot view XML input using XSL style sheet.

  • Configure a Windows PC as network appliance w/o monitor, keyboard and mouse

    - by Joshua Lim
    I intend to use a small form factor PC with Windows 7 Professional installed as a network appliance attached directly to my customer's LAN without connecting a monitor, keyboard or mouse. How should I configure the networking for my PC so that I can access it via say my laptop? I figure that I can do it 2 ways. Attach my laptop to the PC using a crossover cable? Connect via RDP and configure networking. Configure an IP address on the PC before I deliver it to the customer place. At the customer's place, attach the PC to LAN and connect to the IP address which I previously configured from my laptop or from one of the customer's workstations. I know the first way is doable, but is the second way possible? I'm sorry if this question sounds ridiculous - I am Delphi programmer but a novice on networking. Finally, if possible, I hope to make the configuration process web based as I wouldn't like to reveal the fact that I am using Win7 Pro for the network appliance!

  • No network connection for vmware esxi guests

    - by JavaDev
    I'm new to VMware and setting up an Esxi server as a trial with the intention of possibly virtualizing some of our servers in the near future. I have setup ESXi on a Dell poweredge server, and installed a Centos 5.6 and Ubuntu 11.04 guest os on the server. However I cannot get networking on my guest OS's. The host is connected to a network with a DHCP server via a switch and is configured with a static IP. I have the default set-up for networking on the host: both guests are connected to the default vmnic1 adapter via the virtual switch vSwitch0. One thing though, the virtual adapter shows 'Observed IP ranges' to be XXX.XXX.XXX.194-XXX.XXX.XXX.195 (I've blanked out the initial prefixes) i.e just 1 address, even though the network the host is connected to has the usual 255.255.255.0 subnet mask. On the guest machines (using DHCP) by default, I can see an eth0 interface but with no connection or assigned IP address. A physical machine connected to the network gets a DHCP lease as expected. How do I get networking working on my guest OSes? Apologies for the long-winded question.

  • Need some suggestions on my softwares architecture. [Code review]

    - by Sergio Tapia
    I'm making an open source C# library for other developers to use. My key concern is ease of use. This means using intuitive names, intuitive method usage and such. This is the first time I've done something with other people in mind, so I'm really concerned about the quality of the architecture. Plus, I wouldn't mind learning a thing or two. :) I have three classes: Downloader, Parser and Movie I was thinking that it would be best to only expose the Movie class of my library and have Downloader and Parser remain hidden from invocation. Ultimately, I see my library being used like this. using FreeIMDB; public void Test() { var MyMovie = Movie.FindMovie("The Matrix"); //Now MyMovie would have all it's fields set and ready for the big show. } Can you review how I'm planning this, and point out any wrong judgement calls I've made and where I could improve. Remember, my main concern is ease of use. Movie.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Drawing; namespace FreeIMDB { public class Movie { public Image Poster { get; set; } public string Title { get; set; } public DateTime ReleaseDate { get; set; } public string Rating { get; set; } public string Director { get; set; } public List<string> Writers { get; set; } public List<string> Genres { get; set; } public string Tagline { get; set; } public string Plot { get; set; } public List<string> Cast { get; set; } public string Runtime { get; set; } public string Country { get; set; } public string Language { get; set; } public Movie FindMovie(string Title) { Movie film = new Movie(); Parser parser = Parser.FromMovieTitle(Title); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } public Movie FindKnownMovie(string ID) { Movie film = new Movie(); Parser parser = Parser.FromMovieID(ID); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } } } Parser.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using HtmlAgilityPack; namespace FreeIMDB { /// <summary> /// Provides a simple, and intuitive way for searching for movies and actors on IMDB. /// </summary> class Parser { private Downloader downloader = new Downloader(); private HtmlDocument Page; #region "Page Loader Events" private Parser() { } public static Parser FromMovieTitle(string MovieTitle) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindMovie(MovieTitle); return newParser; } public static Parser FromActorName(string ActorName) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindActor(ActorName); return newParser; } public static Parser FromMovieID(string MovieID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownMovie(MovieID); return newParser; } public static Parser FromActorID(string ActorID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownActor(ActorID); return newParser; } #endregion #region "Page Parsing Methods" public string Poster() { //Logic to scrape the Poster URL from the Page element of this. return null; } public string Title() { return null; } public DateTime ReleaseDate() { return null; } #endregion } } ----------------------------------------------- Do you guys think I'm heading towards a good path, or am I setting myself up for a world of hurt later on? My original thought was to separate the downloading, the parsing and the actual populating to easily have an extensible library. Imagine if one day the website changed its HTML, I would then only have to modifiy the parsing class without touching the Downloader.cs or Movie.cs class. Thanks for reading and for helping!

  • Set up two IP addresses with one gateway?

    - by Ahmed
    I would like to ask if it is possible to set up two static IPs from same subnet through one gateway? and How if it is? What I am interested in is described here Routing for multiple uplinks/providers, but in my case I have two IP addresses from one provider, both are on same subnet and off course I have internet access on both. I have two NICs, but I don't mind to go with one if that makes it possible. Any thought is appreciated!
