  • Is a Mission Oriented Architecture (MOA) a better way to describe things than SOA?

    - by Brian Langbecker
    I might sound like a troll, but I would like to seriously understand this deeper. The place I work at has started to use the term MOA, versus SOA as we believe it drives more clarity and want to compare it to the true goals of SOA. A Mission Oriented Architecture is an approach whereby an application is broken down into various business mission elements, with the database, file assets, batch and real time functionality all tightly coupled in terms of delivering that piece of the functionality. The mission allows the developers to focus on a specific piece of functionality to get it right, and to build it with the ability for that piece to scale as an independent entity within the overall application. By tightly coupling the data, file assets and business logic you achieve the goals of working on a very large problem in bite size pieces. Some definitions of SOA mix it up with what is essentially a method call on a web service versus a true "service". As an architect, I have always found it fun getting everyone on the same page regarding SOA. Is it better to call it a "mission" versus a "service"?

  • Assuming "clean code/architecture" is there a difference in "effort" between PHP or Java/J2EE web application development?

    - by PhD
    A client asked us to estimate effort when selecting PHP as the implementation language for his next web-based application. We spent about a week exploring PHP, prototyping, testing etc., We are quite new to this language - may have hacked around it in the past but, let's go with PHP-noobs but application development experts (for the lack of a better, less flattering word :) It seems, that if we write, clean maintainable code, follow separation of concerns, enterprise architecture patters (DAOs etc.) the 'effort' in creating an object-oriented PHP based web-application seems to be the same for a Java based one. Here's our equation for estimating the effort (development/delivery time): ConstructionEffort = f(analysis, design, coding, testing, review, deployment) We were specifically comparing effort estimates in creating an enterprise application with the following: PHP + CakePHP/CodeIgniter (should we have considered others?) Java + Spring + Restlet It's an end-to-end application: Client: Javascript/jQuery + HTML/CSS Middle tier/Business Logic - (Still evaluating PHP/Java) Database: MySQL The effort estimates of the 1st and 3rd tier are constant and relatively independent of the middle tier's technology. At a high level with an initial breakdown into user stories of the requested features as well as a high-level SWAG on the sheer number of classes/SLOC that would be required for PHP doesn't seem to differ by much from what is required of the same in Java. Is this correct? We are basing our initial estimates on the initial prototyping/coding we've done with PHP - we are currently disregarding fluency with the language as a factor, since that'll be an initial hurdle and not a long term impediment IMHO (we also have sufficient time to become quite fluent with PHP). I'm interested in knowing the programmers' perspective with respect to effort when creating similar applications with either of the languages to justify choosing one over the other. Are we missing something here? It seems we are going against popular belief of PHP being quicker to market (or we being very fluent with Java have our vision clouded). It doesn't seem to have any coding/programming effort saving from what we/ve played around with.

  • Is the Entity Component System architecture object oriented by definition?

    - by tieTYT
    Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

  • How to build an API on top of an existing Rails app with NodeJs and what architecture to use?

    - by javiayala
    The explanation I was recently hired by a company that has an old RoR 2.3 application with more than 100k users, a strong SEO strategy with more than 170k indexed urls, native android and ios applications and other custom-made mobile and web applications that rely on a not so good API from the same RoR app. They recently merged with a company from another country as an strategy to grow the business and the profit. They have almost the same stats, a similar strategy and mobile apps. We have just decided that we need to merge the data from both companies and to start a new app from scratch since the RoR app is to old and heavily patched and the app from the other company was built with a custom PHP framework without any documentation. The only good news is that both databases are in MySQL and have a similar structure. The challenge I need to build a new version that: can handle a lot of traffic, preserves the SEO strategies of both companies, serve 2 different domains, and have a strong API that can support legacy mobile apps from both companies and be ready for a new set of native apps. I want to use RoR 3.2 for the main web apps and NodeJs with a Restful API. I know that I need to be very careful with the mobile apps and handle multiple versions of the API. I also think that I need to create a service that can handle a lot IO request since the apps is heavily used to create orders for restaurants at a certain time of the day. The questions With all this in mind: What type of architecture do you recommend me to follow? What gems or node packages do you think will work the best? How do I build a new rails app and keep using the same database structure? Should I use NodeJS to build an API or just build a new service with Ruby? I know that I'm asking to much from you guys, but please help me by answering any topic that you can or by pointing me on the right direction. All your comments and feedback will be extremely appreciated! Thanks!

  • PostgreSQL 8.4 won't start after blackout

    I have problem with starting PostgreSQL 8.4 on Ubuntu 9.10 Server after blackout.

  • Organization &amp; Architecture UNISA Studies &ndash; Chap 4

    - by MarkPearl
    Learning Outcomes Explain the characteristics of memory systems Describe the memory hierarchy Discuss cache memory principles Discuss issues relevant to cache design Describe the cache organization of the Pentium Computer Memory Systems There are key characteristics of memory… Location – internal or external Capacity – expressed in terms of bytes Unit of Transfer – the number of bits read out of or written into memory at a time Access Method – sequential, direct, random or associative From a users perspective the two most important characteristics of memory are… Capacity Performance – access time, memory cycle time, transfer rate The trade off for memory happens along three axis… Faster access time, greater cost per bit Greater capacity, smaller cost per bit Greater capacity, slower access time This leads to people using a tiered approach in their use of memory   As one goes down the hierarchy, the following occurs… Decreasing cost per bit Increasing capacity Increasing access time Decreasing frequency of access of the memory by the processor The use of two levels of memory to reduce average access time works in principle, but only if conditions 1 to 4 apply. A variety of technologies exist that allow us to accomplish this. Thus it is possible to organize data across the hierarchy such that the percentage of accesses to each successively lower level is substantially less than that of the level above. A portion of main memory can be used as a buffer to hold data temporarily that is to be read out to disk. This is sometimes referred to as a disk cache and improves performance in two ways… Disk writes are clustered. Instead of many small transfers of data, we have a few large transfers of data. This improves disk performance and minimizes processor involvement. Some data designed for write-out may be referenced by a program before the next dump to disk. In that case the data is retrieved rapidly from the software cache rather than slowly from disk. Cache Memory Principles Cache memory is substantially faster than main memory. A caching system works as follows.. When a processor attempts to read a word of memory, a check is made to see if this in in cache memory… If it is, the data is supplied, If it is not in the cache, a block of main memory, consisting of a fixed number of words is loaded to the cache. Because of the phenomenon of locality of references, when a block of data is fetched into the cache, it is likely that there will be future references to that same memory location or to other words in the block. Elements of Cache Design While there are a large number of cache implementations, there are a few basic design elements that serve to classify and differentiate cache architectures… Cache Addresses Cache Size Mapping Function Replacement Algorithm Write Policy Line Size Number of Caches Cache Addresses Almost all non-embedded processors support virtual memory. Virtual memory in essence allows a program to address memory from a logical point of view without needing to worry about the amount of physical memory available. When virtual addresses are used the designer may choose to place the cache between the MMU (memory management unit) and the processor or between the MMU and main memory. The disadvantage of virtual memory is that most virtual memory systems supply each application with the same virtual memory address space (each application sees virtual memory starting at memory address 0), which means the cache memory must be completely flushed with each application context switch or extra bits must be added to each line of the cache to identify which virtual address space the address refers to. Cache Size We would like the size of the cache to be small enough so that the overall average cost per bit is close to that of main memory alone and large enough so that the overall average access time is close to that of the cache alone. Also, larger caches are slightly slower than smaller ones. Mapping Function Because there are fewer cache lines than main memory blocks, an algorithm is needed for mapping main memory blocks into cache lines. The choice of mapping function dictates how the cache is organized. Three techniques can be used… Direct – simplest technique, maps each block of main memory into only one possible cache line Associative – Each main memory block to be loaded into any line of the cache Set Associative – exhibits the strengths of both the direct and associative approaches while reducing their disadvantages For detailed explanations of each approach – read the text book (page 148 – 154) Replacement Algorithm For associative and set associating mapping a replacement algorithm is needed to determine which of the existing blocks in the cache must be replaced by a new block. There are four common approaches… LRU (Least recently used) FIFO (First in first out) LFU (Least frequently used) Random selection Write Policy When a block resident in the cache is to be replaced, there are two cases to consider If no writes to that block have happened in the cache – discard it If a write has occurred, a process needs to be initiated where the changes in the cache are propagated back to the main memory. There are several approaches to achieve this including… Write Through – all writes to the cache are done to the main memory as well at the point of the change Write Back – when a block is replaced, all dirty bits are written back to main memory The problem is complicated when we have multiple caches, there are techniques to accommodate for this but I have not summarized them. Line Size When a block of data is retrieved and placed in the cache, not only the desired word but also some number of adjacent words are retrieved. As the block size increases from very small to larger sizes, the hit ratio will at first increase because of the principle of locality, which states that the data in the vicinity of a referenced word are likely to be referenced in the near future. As the block size increases, more useful data are brought into cache. The hit ratio will begin to decrease as the block becomes even bigger and the probability of using the newly fetched information becomes less than the probability of using the newly fetched information that has to be replaced. Two specific effects come into play… Larger blocks reduce the number of blocks that fit into a cache. Because each block fetch overwrites older cache contents, a small number of blocks results in data being overwritten shortly after they are fetched. As a block becomes larger, each additional word is farther from the requested word and therefore less likely to be needed in the near future. The relationship between block size and hit ratio is complex, and no set approach is judged to be the best in all circumstances.   Pentium 4 and ARM cache organizations The processor core consists of four major components: Fetch/decode unit – fetches program instruction in order from the L2 cache, decodes these into a series of micro-operations, and stores the results in the L2 instruction cache Out-of-order execution logic – Schedules execution of the micro-operations subject to data dependencies and resource availability – thus micro-operations may be scheduled for execution in a different order than they were fetched from the instruction stream. As time permits, this unit schedules speculative execution of micro-operations that may be required in the future Execution units – These units execute micro-operations, fetching the required data from the L1 data cache and temporarily storing results in registers Memory subsystem – This unit includes the L2 and L3 caches and the system bus, which is used to access main memory when the L1 and L2 caches have a cache miss and to access the system I/O resources

  • Objective-c design advice for use of different data sources, swapping between test and live

    - by user200341
    I'm in the process of designing an application that is part of a larger piece of work, depending on other people to build an API that the app can make use of to retrieve data. While I was thinking about how to setup this project and design the architecture around it, something occurred to me, and I'm sure many people have been in similar situations. Since my work is depending on other people to complete their tasks, and a test server, this slows work down at my end. So the question is: What's the best practice for creating test repositories and classes, implementing them, and not having to depend on altering several places in the code to swap between the test classes and the actual repositories / proper api calls. Contemplate the following scenario: GetDataFromApiCommand *getDataCommand = [[GetDataFromApiCommand alloc]init]; getDataCommand.delegate = self; [getDataCommand getData]; Once the data is available via the API, "GetDataFromApiCommand" could use the actual API, but until then a set of mock data could be returned upon the call of [getDataCommand getData] There might be multiple instances of this, in various places in the code, so replacing all of them wherever they are, is a slow and painful process which inevitably leads to one or two being overlooked. In strongly typed languages we could use dependency injection and just alter one place. In objective-c a factory pattern could be implemented, but is that the best route to go for this? GetDataFromApiCommand *getDataCommand = [GetDataFromApiCommandFactory buildGetDataFromApiCommand]; getDataCommand.delegate = self; [getDataCommand getData]; What is the best practices to achieve this result? Since this would be most useful, even if you have the actual API available, to run tests, or work off-line, the ApiCommands would not necessarily have to be replaced permanently, but the option to select "Do I want to use TestApiCommand or ApiCommand". It is more interesting to have the option to switch between: All commands are test and All command use the live API, rather than selecting them one by one, however that would also be useful to do for testing one or two actual API commands, mixing them with test data. EDIT The way I have chosen to go with this is to use the factory pattern. I set up the factory as follows: @implementation ApiCommandFactory + (ApiCommand *)newApiCommand { // return [[ApiCommand alloc]init]; return [[ApiCommandMock alloc]init]; } @end And anywhere I want to use the ApiCommand class: GetDataFromApiCommand *getDataCommand = [ApiCommandFactory newApiCommand]; When the actual API call is required, the comments can be removed and the mock can be commented out. Using new in the message name implies that who ever uses the factory to get an object, is responsible for releasing it (since we want to avoid autorelease on the iPhone). If additional parameters are required, the factory needs to take these into consideration i.e: [ApiCommandFactory newSecondApiCommand:@"param1"]; This will work quite well with repositories as well.

  • Categorized Document Management System

    - by cmptrgeekken
    At the company I work for, we have an intranet that provides employees with access to a wide variety of documents. These documents fall into several categories and subcategories, and each of these categories have their own web page. Below is one such page (each of the links shown will link to a similar view for that category): We currently store each document as a file on the web server and hand-code links to these documents whenever we need to add a new document. This is tedious and error-prone, and it also means we lack any sort of security for accessing these documents. I began looking into document management systems (like KnowledgeTree and OpenKM), however, none of these systems seem to provide a categorized view like in the preview above. My question is ... does anyone know of any Document Management System that allow for the type of flexibility we currently have with hand-coding links to our documents into various webpages (major and minor , while also providing security, ease of use, and (less important) version control? Or do you think I'd be better off developing such a system from scratch?

  • WCF on Windows Phone 7 (Silverlight 4)

    - by Igor Zevaka
    Has anyone been able to communicate using WCF on Windows Phone Series 7 emulator? I've been trying for the past two days and it's just happening for me. I can get a normal Silverlight control to work in both Silverlight 3 and Silverlight 4, but not the phone version. Here are two versions that I've tried: Version 1 - Using Async Pattern BasicHttpBinding basicHttpBinding = new BasicHttpBinding(); EndpointAddress endpointAddress = new EndpointAddress("http://localhost/wcf/Authentication.svc"); Wcf.IAuthentication auth1 = new ChannelFactory<Wcf.IAuthentication>(basicHttpBinding, endpointAddress).CreateChannel(endpointAddress); AsyncCallback callback = (result) => { Action<string> write = (str) => { this.Dispatcher.BeginInvoke(delegate { //Display something }); }; try { Wcf.IAuthentication auth = result.AsyncState as Wcf.IAuthentication; Wcf.AuthenticationResponse response = auth.EndLogin(result); write(response.Success.ToString()); } catch (Exception ex) { write(ex.Message); System.Diagnostics.Debug.WriteLine(ex.Message); } }; auth1.BeginLogin("user0", "test0", callback, auth1); This version breaks on this line: Wcf.IAuthentication auth1 = new ChannelFactory<Wcf.IAuthentication>(basicHttpBinding, endpointAddress).CreateChannel(endpointAddress); Throwing System.NotSupportedException. The exception is not very descriptive and the callstack is equally not very helpful: at System.ServiceModel.DiagnosticUtility.ExceptionUtility.BuildMessage(Exception x) at System.ServiceModel.DiagnosticUtility.ExceptionUtility.LogException(Exception x) at System.ServiceModel.DiagnosticUtility.ExceptionUtility.ThrowHelperError(Exception e) at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address) at WindowsPhoneApplication2.MainPage.DoLogin() .... Version 2 - Blocking WCF call Here is the version that doesn't use the async pattern. [System.ServiceModel.ServiceContract] public interface IAuthentication { [System.ServiceModel.OperationContract] AuthenticationResponse Login(string user, string password); } public class WcfClientBase<TChannel> : System.ServiceModel.ClientBase<TChannel> where TChannel : class { public WcfClientBase(string name, bool streaming) : base(GetBinding(streaming), GetEndpoint(name)) { ClientCredentials.UserName.UserName = WcfConfig.UserName; ClientCredentials.UserName.Password = WcfConfig.Password; } public WcfClientBase(string name) : this(name, false) {} private static System.ServiceModel.Channels.Binding GetBinding(bool streaming) { System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding(); binding.MaxReceivedMessageSize = 1073741824; if(streaming) { //binding.TransferMode = System.ServiceModel.TransferMode.Streamed; } /*if(XXXURLXXX.StartsWith("https")) { binding.Security.Mode = BasicHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; }*/ return binding; } private static System.ServiceModel.EndpointAddress GetEndpoint(string name) { return new System.ServiceModel.EndpointAddress(WcfConfig.Endpoint + name + ".svc"); } protected override TChannel CreateChannel() { throw new System.NotImplementedException(); } } auth.Login("test0", "password0"); This version crashes in System.ServiceModel.ClientBase<TChannel> constructor. The call stack is a bit different: at System.Reflection.MethodInfo.get_ReturnParameter() at System.ServiceModel.Description.ServiceReflector.HasNoDisposableParameters(MethodInfo methodInfo) at System.ServiceModel.Description.TypeLoader.CreateOperationDescription(ContractDescription contractDescription, MethodInfo methodInfo, MessageDirection direction, ContractReflectionInfo reflectionInfo, ContractDescription declaringContract) at System.ServiceModel.Description.TypeLoader.CreateOperationDescriptions(ContractDescription contractDescription, ContractReflectionInfo reflectionInfo, Type contractToGetMethodsFrom, ContractDescription declaringContract, MessageDirection direction) at System.ServiceModel.Description.TypeLoader.CreateContractDescription(ServiceContractAttribute contractAttr, Type contractType, Type serviceType, ContractReflectionInfo& reflectionInfo, Object serviceImplementation) at System.ServiceModel.Description.TypeLoader.LoadContractDescriptionHelper(Type contractType, Type serviceType, Object serviceImplementation) at System.ServiceModel.Description.TypeLoader.LoadContractDescription(Type contractType) at System.ServiceModel.ChannelFactory1.CreateDescription() at System.ServiceModel.ChannelFactory.InitializeEndpoint(Binding binding, EndpointAddress address) at System.ServiceModel.ChannelFactory1..ctor(Binding binding, EndpointAddress remoteAddress) at System.ServiceModel.ClientBase1..ctor(Binding binding, EndpointAddress remoteAddress) at Wcf.WcfClientBase1..ctor(String name, Boolean streaming) at Wcf.WcfClientBase`1..ctor(String name) at Wcf.AuthenticationClient..ctor() at WindowsPhoneApplication2.MainPage.DoLogin() ... Any ideas?

  • call python with system() in R to run a python script emulating the python console

    - by Yihui
    I want to pass a chunk of Python code to Python in R with something like system('python ...'), and I'm wondering if there is an easy way to emulate the python console in this case. For example, suppose the code is "print 'hello world'", how can I get the output like this in R? >>> print 'hello world' hello world This only shows the output: > system("python -c 'print \"hello world\"'") hello world Thanks! BTW, I asked in r-help but have not got a response yet (if I do, I'll post the answer here).

  • `# probe: true` in /etc/rc.d/init.d/* files on a RedHat system

    - by Chen Levy
    Some files (e.g. nfs, nfslock, bind) in my /etc/rc.d/init.d/ directory have in their comment header a line such as: # probe: true I found that those particular scripts has the probe verb i.e.: service nfs probe But this is due to the fact that the mentioned scripts has code that deals with the probe verb. I find no mention of the # probe: true notation in chkconfig man page, nor in any related man pages. Googleing for it also didn't help. Is there a real significance for that line, or is it pure documentation?

  • Problems deploying MVC2 - Could not load type 'System.Web.Mvc.UrlParameter'

    - by Evgeny
    Hi Everyone, I have problems deploying MVC2 application to my hosting. It shows the following error: Could not load type 'System.Web.Mvc.UrlParameter' from assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. It looks like it does not understand the new "optional URL parameters" feature of MVC2. This is just a simple test application I created with "New Project" wizard in VWD 2008. It works ok localy both in IIS and Visual Studio web servers. MVC1 web sites are working ok on the hosting server. I've contacted the hosting support and they installed MVC2 but the problem still exists. The web site is working in ASP.NET 2.0 integrated pipeline mode. Does anyone know why it is happening? Thank you!

  • DirectoryServicesCOMException when working with System.DirectoryServices.AccountManagement

    - by antik
    I'm attempting to determine whether a user is a member of a given group using System.DirectoryServices.AccountManagment. I'm doing this inside a SharePoint WebPart in SharePoint 2007 on a 64-bit system. Project targets .NET 3.5 Impersonation is enabled in the web.config. The IIS Site in question is using an IIS App Pool with a domain user configured as the identity. I am able to instantiate a PrincipalContext as such: PrincipalContext pc = new PrincipalContext(ContextType.Domain) Next, I try to grab a principal: using (PrincipalContext pc = new PrincipalContext(ContextType.Domain)) { GroupPrincipal group = GroupPrincipal.FindByIdentity(pc, "MYDOMAIN\somegroup"); // snip: exception thrown by line above. } Both the above and UserPrincipal.FindByIdentity with a user SAM throw a DirectoryServicesCOMException: "Logon failure: Unknown user name or bad password" I've tried passing in a complete SAMAccountName to either FindByIdentity (in the form of MYDOMAIN\username) or just the username with no change in behavior. I've tried executing the code with other credentials using both the HostingEnvironment.Impersonate and SPSecurity.RunWithElevatedPrivileges approaches and also experience the same result. I've also tried instantiating my context with the domain name in place: Principal Context pc = new PrincipalContext(ContextType.Domain, "MYDOMAIN"); This throws a PrincipalServerDownException: "The server could not be contacted." I'm working on a reasonably hardened server. I did not lock the system down so I am unsure exactly what has been done to it. If there are credentials I need to allocate to my pool identity's user or in the domain security policy in order for these to work, I can configure the domain accordingly. Are there any settings that would be preventing my code from running? Am I missing something in the code itself? Is this just not possible in a SharePoint web? EDIT: Given further testing, my code functions correctly when tested in a Console application targeting .NET 4.0. I targeted a different framework because I didn't have AccountManagement available to me in the console app when targeting .NET 3.5 for some reason. using (PrincipalContext pc = new PrincipalContext(ContextType.Domain)) using (UserPrincipal adUser = UserPrincipal.FindByIdentity(pc, "MYDOMAIN\joe.user")) using (GroupPrincipal adGroup = GroupPrincipal.FindByIdentity(pc, "MYDOMAIN\user group")) { if (adUser.IsMemberOf(adGroup)) { Console.WriteLine("User is a member!"); } else { Console.WriteLine("User is NOT a member."); } } What varies in my SharePoint environment that might prohibit this function from executing?

  • Using System.Security.SecureString in .NET Remoting App?

    - by Beaner
    I am developing a Remoting application where a client looks up store specific information to login to a web server. It sets the user name and passwords in a class that stores the properties as System.Security.SecureString. I then try to pass the class with the login credentials to a server object that uses it to connect to the web host, get and some information back. When I call the server method I this error:Type 'System.Security.SecureString' in Assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable. The class that contains the SecureStrings is marked as serializeable, and this was working while developing until I added the SecureString properties. Is there something I need to do to make this work, or am I going to have to change SecureString to String?

  • How to add SQLite (SQLite.NET) to my C# project

    I followed the instructions in the documentation: Scenario 1: Version Independent (does not use the Global Assembly Cache) This method allows you to drop any new version of the System.Data.SQLite.DLL into your application's folder and use it without any code modifications or recompiling. Add the following code to your app.config file: <configuration> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> My app.config file now looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > <section name="DataFeed.DataFeedSettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <DataFeed.DataFeedSettings> <setting name="eodData" serializeAs="String"> <value>False</value> </setting> </DataFeed.DataFeedSettings> </userSettings> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /> </DbProviderFactories> </system.data> </configuration> My project is called "DataFeed": using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.SQLite; //<-- Causes compiler error namespace DataFeed { class Program { static void Main(string[] args) { } } } The error I get is: .\dev\DataFeed\Program.cs(5,19): error CS0234: The type or namespace name 'SQLite' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) I'm not using the GAC, I simply dropped the System.Data.SQLite.dll into my .\dev\DataFeed\ folder. I thought that all I needed to do is add the DLL to the project folder as it was mentioned in the documentation. Any hints on how to actually make this work?

  • Problem making system calls with PHP scripts

    - by mazin k.
    I have the following PHP script: <?php $fortune = `fortune`; echo $fortune; ?> but the output is simply blank (no visible errors thrown). However, if I run php -a, it works: php > echo `fortune`; Be careful of reading health books, you might die of a misprint. -- Mark Twain php > Am I missing a config directive or something that would cause this? Edit: So, I tried running my script using $ php-cgi fortunetest.php and it worked as expected. Maybe the issue is with Apache2?

  • Windows 2000 uninstall on a dual-boot 2000/XP system

    - by Viktor
    While several questions have already been answered about removing an OS from a dual-booting machine, most refer to Windows 7 vs. Linux/Vista/XP. I have W2K installed on my older HDD (Drive C). Later on I bought a new HDD and installed XP's under W2K environment. Each time I turned my PC on, I had the choice of W2K or XP OS, which I still have. I eventually stopped using the w2k OS and as the older HDD where this OS is installed is getting old, I plan to remove it completely. The problem is that the active master boot record is on this very HDD. So when I remove the HDD, I get no OS loader, no matter what boot drive I choose in BIOS. Apparently I have to set the boot record on the newer HDD with XP's. Some advise to use the bootable XP CD and try to set the active MBR from there.. I don't have the CD anymore. Regardless, I suspect there is much less to solving this problem than running the recovery console, like a simple boot.ini file edit. But I might be wrong.

  • System calls on Windows

    - by b-gen-jack-o-neill
    Hi, I just want to ask, I know that standart system calls in Linux are done by int instruction pointing into Interrupt Vector Table. I assume this is similiar on Windows. But, how do you call some higher-level specific system routines? Such as how do you tell Windows to create a window? I know this is handled by the code in the dll, but what actually happend at assembler-instruction level? Does the routine in dll calls software interrupt by int instruction, or is there any different approach to handle this? Thanks.

  • gparted installed on OpenSuse shows all file system types as greyed out except for hfs

    - by cmdematos.com
    I have had this problem before and fixed it, but I don't recall how I did it and I did not record it (sadness :( ) I have all the requisite commands installed on OpenSuse to support gparted's efforts in creating any of the supported file systems. I recall that the problem was that gparted could not find the commands, in any event all the file systems are greyed out in the context menu except for the legacy hfs partition which only supports < 2gb. Even extfs2-extfs4 are greyed out. How do I fix this?

  • Default Screensaver on Mac OS X

    - by DanieL
    Hi, How do I change the default screensaver in Mac OS X using shell. I am writing a script to customize computers that I need to distribute. In particular I would like them all to have the same default screensaver. How could I change this in a script? So far I have done the following: I have a com.apple.screensaver.default.plist file with the screensaver settings I want in it, and in the script I copy it to /Users/guest/Library/Preferences/ByHost/com.apple.screensaver.${UUID}.plist where UUID is the relevant value. I have modified /System/Library/Frameworks/Screensaver.framework/Versions/A/Resources/EngineDefaults.plist to have the screensaver I want as the default settings. But when I open Screensaver settings in System Preferences after running the script, the default screensaver is Flurry! What can I do to make this work? Thanks, ChilisWorld
