• wsdl interoperability problems

  - by manu1001

  I wrote a .asmx web service which I'm trying to consume from a java client. I'm using axis2's wsdl2java to generate code. But it says that the wsdl is invalid. What exactly is the problem here? It is .net which generated the wsdl automatically after all. Are there problems with wsdl standards, rather the lack of them? What can I do now? I'm putting the wsdl here for reference. <?xml version="1.0" encoding="utf-8"?> <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns="http://localhost:4148/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" targetNamespace="http://localhost:4148/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"> <wsdl:types> <s:schema elementFormDefault="qualified" targetNamespace="http://localhost:4148/"> <s:element name="GetUser"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="uid" type="s:string" /> </s:sequence> </s:complexType> </s:element> <s:element name="GetUserResponse"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="GetUserResult" type="tns:User" /> </s:sequence> </s:complexType> </s:element> <s:complexType name="User"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="HA" type="tns:ComplexT" /> <s:element minOccurs="0" maxOccurs="1" name="AP" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="AL" type="tns:ArrayOfString" /> <s:element minOccurs="0" maxOccurs="1" name="CO" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="EP" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="ND" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="AE" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="IE" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="IN" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="HM" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="AN" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="MI" type="tns:ArrayOfString" /> <s:element minOccurs="0" maxOccurs="1" name="NO" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="TL" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="UI" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="DT" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="PT" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="PO" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="AE" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="ME" type="tns:ArrayOfString" /> </s:sequence> </s:complexType> <s:complexType name="ComplexT"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="SR" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="CI" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="TA" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="SC" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="RU" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="HN" type="s:string" /> </s:sequence> </s:complexType> <s:complexType name="ArrayOfString"> <s:sequence> <s:element minOccurs="0" maxOccurs="unbounded" name="string" nillable="true" type="s:string" /> </s:sequence> </s:complexType> </s:schema> </wsdl:types> <wsdl:message name="GetUserSoapIn"> <wsdl:part name="parameters" element="tns:GetUser" /> </wsdl:message> <wsdl:message name="GetUserSoapOut"> <wsdl:part name="parameters" element="tns:GetUserResponse" /> </wsdl:message> <wsdl:portType name="UserServiceSoap"> <wsdl:operation name="GetUser"> <wsdl:input message="tns:GetUserSoapIn" /> <wsdl:output message="tns:GetUserSoapOut" /> </wsdl:operation> </wsdl:portType> <wsdl:binding name="UserServiceSoap" type="tns:UserServiceSoap"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="GetUser"> <soap:operation soapAction="http://localhost:4148/GetUser" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:binding name="UserServiceSoap12" type="tns:UserServiceSoap"> <soap12:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="GetUser"> <soap12:operation soapAction="http://localhost:4148/GetUser" style="document" /> <wsdl:input> <soap12:body use="literal" /> </wsdl:input> <wsdl:output> <soap12:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="UserService"> <wsdl:port name="UserServiceSoap" binding="tns:UserServiceSoap"> <soap:address location="http://localhost:4148/Service/UserService.asmx" /> </wsdl:port> <wsdl:port name="UserServiceSoap12" binding="tns:UserServiceSoap12"> <soap12:address location="http://localhost:4148/Service/UserService.asmx" /> </wsdl:port> </wsdl:service> </wsdl:definitions>

• .NET Compact COM interoperability

  - by markhor

  I have the following code in a full .NET framework solution: public delegate int CreateObjectDelegate( [In] ref Guid classID, [In] ref Guid interfaceID, [MarshalAs(UnmanagedType.Interface)] out object outObject); ... var createObject = (NativeMethods.CreateObjectDelegate) Marshal.GetDelegateForFunctionPointer( NativeMethods.GetProcAddress(_modulePtr, "CreateObject"), typeof (NativeMethods.CreateObjectDelegate)); object result; Guid interfaceId = _guid; Guid classID = _classId; createObject(ref classID, ref interfaceId, out result); The purpose is to create the needed COM object at runtime. Is it possible with any .NET compact framework? Note that it doesn't have Marshal.GetDelegateForFunctionPointer.

• Interoperability between two AES algorithms

  - by lpfavreau

  Hello, I'm new to cryptography and I'm building some test applications to try and understand the basics of it. I'm not trying to build the algorithms from scratch but I'm trying to make two different AES-256 implementation talk to each other. I've got a database that was populated with this Javascript implementation stored in Base64. Now, I'm trying to get an Objective-C method to decrypt its content but I'm a little lost as to where the differences in the implementations are. I'm able to encrypt/decrypt in Javascript and I'm able to encrypt/decrypt in Cocoa but cannot make a string encrypted in Javascript decrypted in Cocoa or vice-versa. I'm guessing it's related to the initialization vector, nonce, counter mode of operation or all of these, which quite frankly, doesn't speak to me at the moment. Here's what I'm using in Objective-C, adapted mainly from this and this: @implementation NSString (Crypto) - (NSString *)encryptAES256:(NSString *)key { NSData *input = [self dataUsingEncoding: NSUTF8StringEncoding]; NSData *output = [NSString cryptoAES256:input key:key doEncrypt:TRUE]; return [Base64 encode:output]; } - (NSString *)decryptAES256:(NSString *)key { NSData *input = [Base64 decode:self]; NSData *output = [NSString cryptoAES256:input key:key doEncrypt:FALSE]; return [[[NSString alloc] initWithData:output encoding:NSUTF8StringEncoding] autorelease]; } + (NSData *)cryptoAES256:(NSData *)input key:(NSString *)key doEncrypt:(BOOL)doEncrypt { // 'key' should be 32 bytes for AES256, will be null-padded otherwise char keyPtr[kCCKeySizeAES256 + 1]; // room for terminator (unused) bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding) // fetch key data [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [input length]; // See the doc: For block ciphers, the output size will always be less than or // equal to the input size plus the size of one block. // That's why we need to add the size of one block here size_t bufferSize = dataLength + kCCBlockSizeAES128; void* buffer = malloc(bufferSize); size_t numBytesCrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(doEncrypt ? kCCEncrypt : kCCDecrypt, kCCAlgorithmAES128, kCCOptionECBMode | kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES256, nil, // initialization vector (optional) [input bytes], dataLength, // input buffer, bufferSize, // output &numBytesCrypted ); if (cryptStatus == kCCSuccess) { // the returned NSData takes ownership of the buffer and will free it on deallocation return [NSData dataWithBytesNoCopy:buffer length:numBytesCrypted]; } free(buffer); // free the buffer; return nil; } @end Of course, the input is Base64 decoded beforehand. I see that each encryption with the same key and same content in Javascript gives a different encrypted string, which is not the case with the Objective-C implementation that always give the same encrypted string. I've read the answers of this post and it makes me believe I'm right about something along the lines of vector initialization but I'd need your help to pinpoint what's going on exactly. Thank you!

• Check user language selection in NSIS MUI2

  - by wls

  I have multiple language packs in my NSIS installer, using the MUI2 interface. Now I try to select the language pack, which is installed by the "Typical" installation type according to the user's chosen setup language. My problem is, that I can't figure out, how to get the user's language selection. I already tried to access the variables $LANGUAGE and $mui.LangDLL.RegistryLanguage, as well as trying to compare a defined language string to a specific translation string, but without success.

• Android Bluetooth Cross Platform Interoperability

  - by Philipp

  Hi, I have a Bluetooth service that I programmed for .Net on a Windows machine and I would like my Android 2.1 phone to connect to it. The server is listening for the same UUID which the Android is using to connect. But the connection is failing. When I try to connect to devices that are not listening for that UUID, I get an exception with the message "Service discovery failed", but when I try to connect to the server that is listening for the right UUID a message box pops up saying: "There was a problem pairing with bluetooth device." And I get an exception with the message "Connection timed out." So it looks like the server and the Android are communicating, but there is some sort of failure during handshaking. I know that the Android requires that the server is paired with the phone and also encrypts the communication channel. Does anyone know which specifications are used to do this? I would love to get my server to respond properly to the connection attempt. Thanks!

• Best tool for monitoring Coldfusion interoperability with .Net web service

  - by John Galt

  Is there a tool to see the message sent to webservice hosted on an IIS server? I have a webservice written in .Net and our ColdFusion people are having trouble building a "complex" parameter. This problem is described from a ColdFusion perspective at: adobe forum question It runs when called from a .net client. While hosted on a server inside our LAN, I put it out on a public server so the WSDL could be viewed: please take a quick look at this WSDL here When the CF developer runs her code, she gets: java.lang.IllegalArgumentException: argument type mismatch ...and I am wondering if there is a tool I could run on the server that hosts my webservice to see if it is even entering the WS or is being rejected by Java code that CF uses and is not really even getting to my webservice.

• Visual Basic 2010 Language Enhancements

  Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10 (also referred to as Visual Basic 2010). Previously, the C# and Visual Basic programming languages were managed by two separate teams within Microsoft, which helps explain why features found in one language was not necessarily found in the other. For example, C# 3.0 introduced collection initializers, which enable developers to define the contents of a collection when declaring it; however, Visual Basic 9 did not support collection initializers. Conversely, Visual Basic has long supported optional parameters in methods, whereas C# did not. Recently, Microsoft merged the Visual Basic and C# teams to help ensure that C# and Visual Basic grow together. As explained by Microsoft program manager Jonathan Aneja, "The intent is to make the languages advance together. When major functionality is introduced in one language, it should appear in the other as well. ... [T]hat any task you can do in one language should be as simple in the other." To this end, with version 4.0 C# now supports optional parameters and named arguments, two features that have long been part of Visual Basic's vernacular. And, likewise, Visual Basic has been updated to include a number of C# features that it was previously missing. This article explores some of these new features that were added to Visual Basic 2010.

• AJAX Control Toolkit - Globalization (Language)

  - by Guilherme Cardoso

  For those who use AjaxToolKit controls presenting a language-dependent data (the CalendarExternder with the names of the months and weeks, for example) you can change the language to be presented in a simple way. In Web.Config let's define the primary culture as follows: < system . web > <System. Web> < globalization uiCulture = "pt-pt" culture = "pt-pt" /> <Globalization UICulture = "en-us" culture = "en-us" /> ... ...  In this example I'm using Portuguese. To finish it is necessary to change our ScriptManager. Be it the ToolScriptManager AjaxToolKit or belonging to the ScriptManager's framework. NET, the properties as a vibrant and true are the EnableScriptGlobalization EnableScriptLocalization. < cc1 : ToolkitScriptManager ID = "ToolkitScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true" > <Cc1: ToolkitScriptManager ID = "ToolkitScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true"> </ cc1 : ToolkitScriptManager > </ Cc1: ToolkitScriptManager> or < asp : ScriptManager ID = "ScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true" > <Asp: ScriptManager ID = "ScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true"> </ asp : ScriptManager > </ Asp: ScriptManager>   Like hus we use the controls on AjaxToolKit, always using the Portuguese language. It is important that AjaxTookKit is updated to avoid shortages or errors in translation, though I have not updated by this error in the ModalPopup the latest version, and any controls that I have used are translated correctly.

• Visual Studio, .NET Framework, and language versions

  - by Scott Dorman

  Every so often a question comes up about how Visual Studio, the .NET Framework, and a .NET programming language relate to each other. Mostly, these questions have to do with versions. The reality is that these are actually three different “products” that are versioned independently of each other but are related. Looking at how Visual Studio, the .NET Framework version, and the CLR versions relate to each other results in the following: Visual Studio CLR .NET Framework Visual Studio .NET (Ranier) 1.0.3705 1.0 Visual Studio 2003 (Everett) 1.1.4322 1.1 Visual Studio 2005 (Whidbey) 2.0.50727 2.0 Visual Studio 2005 with .NET 3.0 Extensions 2.0.50727 2.0, 3.0 Visual Studio 2008 (Orcas) 2.0.50727 2.0 SP1, 3.0 SP1, 3.5 Visual Studio 2008 SP1 2.0.50727 2.0 SP2, 3.0 SP2, 3.5 SP1 Visual Studio 2010 (Hawaii) 4.0.30319 4.0 The actual Visual Studio version numbers are: Product Name Version Ship Date Visual Studio .NET 7.0.???? 02/2002 Visual Studio .NET 2002 SP1 7.0.????   Visual Studio 2003 7.1.???? 04/2003 Visual Studio 2003 SP1 7.1.6030 09/13/2006 Visual Studio 2005 8.0.5072   Visual Studio 2005 SP1   12/14/2006 Visual Studio 2008 9.0.21022.8 11/19/2007 Visual Studio 2008 SP1 9.0.30729.1   Visual Studio 2010 10.0.30319.1 04/12/2010 (For those entries that are missing information, it simply means that I didn’t already know it and/or couldn’t easily find it online.) So far, everything seems fairly reasonable and isn’t terribly difficult to keep coordinated. However, when you start trying to find language versions and how those relate to .NET Framework, CLR, or Visual Studio releases it becomes more difficult. The breakdown for the programming languages that are part of Visual Studio are: Framework CLR Language     C# VB F# 1.0 1.0.3705 1.0 7.0 - 1.1 1.1.4322 1.1 7.1 - 2.0 2.0.50727 2.0 8.0 - 3.0 2.0.50727 2.0 8.0 - 3.5 2.0.50727 2.0 9.0 - 4.0 4.0.30319 4.0 10.0 2.0   Technorati Tags: Visual Studio,.NET

• SEO for Country & Language Specific content.

  - by kecebongsoft

  Currently I am creating a website which has a common topic for an article, but it's going to be different content for each country, and also, each of that content will be provided in several languages. And this mechanism exists in most of the parts in the website. For example, I have an article about tax. This article has to be different for each country, for example china. And tax content for china should be written in china AND english language (for non china-speaker). What is the best URL pattern to handle this? What I've been thinking is, using a sub folder (/country-code/language-code/) such as: www.example.com/cn/cn/tax www.example.com/cn/en/tax Or using top level domain such as: www.example.cn/cn/tax www.example.cn/en/tax Or subdomain such as cn.example.com/cn/tax cn.example.com/en/tax I think I will not prefer the last option since I might need to use subdomain for other purpose. Which left only subfolder and TLDN. I've read some articles saying that TLDN is good for localized content (language-specific content), but in my case, my TLDN will also has english contents (for non local speaker) which is specific only to that particular country (also the purpose of this is to let people from other country easily search it through google). What is the best pattern to pick and why?.

• Is a Model Driven Architecture in Language Oriented Programming (MPS) feasible at this time

  - by Steven Jeuris

  As a side project I am developing some sort of DSL where I describe a data model, and generate desired code files from it. I believe this is called Model Driven Architecture. My partial existing implementation uses C#, CodeDOM, XML and XSLT to do this manually. I discovered there already exist better environments to do this in. The one which fascinated me the most is called MPS, which follows the Language Oriented Programming paradigm. This article, written by a cofounder of JetBrains was a real eye opener for me. I truly believe LOP has a very good chance of becoming the next big programming paradigm once it has broader support. From my short experience with MPS, I noticed it is still mainly Java-oriented. My question is, how feasible is it to generate code files for other (multiple) languages instead of just Java. I don't need full language support from the start, so preferably, I need to be able to implement a language in a agile way. E.g. first support only one type, add access modifiers, ... Perhaps some other (free) environment already provides this out of the box. P.S.: I find it important to have a lot of control over the naming conventions and such of the generated code. This is one of the reasons why I started my own implementation.

• Which language meets my needs? [closed]

  - by Gerald Goward

  I am a junior C# developer, working for half a year now. In my company I am working on some enterprise projects and after doing it for quite some time I understood that I dont like enterprise projects. I have my own browser-game written in PHP+MySql with some simple HTML+CSS and I have 300 active (those, who entered the game at least once per 5 days) players currently :) After thinking quite some time I understood that I am interested in: 1). Web-development AND 2). standalone programs (but not enterprise ones). 3). Development for mobile platforms is also nice, Android/iOs. 1st and 2nd categories are what I want the most. Android/iOs is good too. I am NOT interested in big systems which are hard to integrate, I am not interested in enterprise systems. In future I would like to start my own business/projects. I would like to create my own projects or/and create a small programmers company to create and release own products. Please tell me what programming language(s)/technologies would you advice me for it? Thanks alot! UPD: It's NOT a "which language is better" or any flame/holywar generating topic since I ask for language that suits my EXACT needs better. I believe C++ is better for low-level coding, while PHP is good for web-development and Object-C being made for iOs. I am still newbie at programming so dont hate me please.

• Which language is more suitable heavy file tasks?

  - by All

  I need to write a script (based on basic functions) to process /image/audio/video files. The process is mainly filesystem tasks and converts. The database of files has been stored by mysql. The script is simple but cause heavy tasks on the system; for example renaming/converting/copying thousands of file in a run. The script does not read the content of files into memory, it just manage the commands for sub-processes. The main weight is on the communication with filesystem. The script will be used regularly for new files. My concern is about performance. I am thinking of Shell script a complied language like C Please advise which programming language is more suitable for this purpose and why? UPDATE: An example is to scan a folder for images, convert them with ImageMagick, move files to destination folder, get file info, then update the database. As you can see, the process has no room for optimization, and most of languages have similar APIs for popular programs like ImageMagick, MySQL, etc. Thus, it can be written in any language. I just wish to reduce resource usage by speeding up the long loop. NOTE: I know that questions about comparing languages are not favorable, but I really had problem to choose, because the problems can appear in action.

• Script language native extensions - avoiding name collisions and cluttering others' namespace

  - by H2CO3

  I have developed a small scripting language and I've just started writing the very first native library bindings. This is practically the first time I'm writing a native extension to a script language, so I've run into a conceptual issue. I'd like to write glue code for popular libraries so that they can be used from this language, and because of the design of the engine I've written, this is achieved using an array of C structs describing the function name visible by the virtual machine, along with a function pointer. Thus, a native binding is really just a global array variable, and now I must obviously give it a (preferably good) name. In C, it's idiomatic to put one's own functions in a "namespace" by prepending a custom prefix to function names, as in myscript_parse_source() or myscript_run_bytecode(). The custom name shall ideally describe the name of the library which it is part of. Here arises the confusion. Let's say I'm writing a binding for libcURL. In this case, it seems reasonable to call my extension library curl_myscript_binding, like this: MYSCRIPT_API const MyScriptExtFunc curl_myscript_lib[10]; But now this collides with the curl namespace. (I have even thought about calling it curlmyscript_lib but unfortunately, libcURL does not exclusively use the curl_ prefix -- the public APIs contain macros like CURLCODE_* and CURLOPT_*, so I assume this would clutter the namespace as well.) Another option would be to declare it as myscript_curl_lib, but that's good only as long as I'm the only one who writes bindings (since I know what I am doing with my namespace). As soon as other contributors start to add their own native bindings, they now clutter the myscript namespace. (I've done some research, and it seems that for example the Perl cURL binding follows this pattern. Not sure what I should think about that...) So how do you suggest I name my variables? Are there any general guidelines that should be followed?

• Middle tier language for interfacing C/C++ with db and web app

  - by ggkmath

  I have a web application requiring a middle-tier language to communicate between an oracle database and math routines on a Linux server and a flex-based application on a client. I'm not a software expert, and need recommendations for which language to use for the middle-tier. The math routines are currently in Matlab but will be ported to C (or C++) as shared libraries. Thus, by default there's some C or C++ communication necessary. These routines rely on FFTW (www.fftw.org), which is called directly from C or C++ (thus, I don't see re-writing these routines in another language). The middle tier must manage traffic between the client, the math routines, and the Oracle database. The client will trigger the math routines aynchronously, and the results saved in the db and transferred back to the client, etc. The middle-tier will also need to authenticate user accounts/passwords, and send out various administrative emails. Originally I thought PhP the obvious choice, but interfacing asychronously multiple clients with the C or C++ routines doesn't seem straightforward. Then I thought, why not just keep the whole middle tier in C or C++, but I'm not sure if this is done in the industry (C or C++ doesn't seem as web-friendly as other languages). There's always Jave + JNI, but maybe that introduces other complications (not sure). Any feedback appreciated.

• Best scripting language for project [on hold]

  - by Dave

  This is a subjective question, but I don't know where else to ask it. I'd appreciate it if someone could direct me to an appropriate scripting language for my project. I'm a little new at this so I'd appreciate any help. The project is a website that will display a list of photo subject groups (such as "nature" "people" "sports" etc) on the home page. The photos will all be in subdirectories of the main photo directory (photos) and each subject group will represent a subdirectory in photos. For example in directory photos there might be 3 subdirectories, "nature" "people" "sports" and in each of those subdirectories there will be the actual photos. The idea is that when the website owner wants to update/add/delete a subject group all he has to do is add, delete or update a subdirectory of the photos directory. This means, I think, that I need a scripting language that can read the directories and files in the website and then send a web page with the information in it. What is the simplest and easiest scripting language to do this in? Any ideas? Thanks

• Ubiquitous Language and Custom types

  - by EdvRusj

  Note that my question is referring to those attributes that even on their own already represent a concept ( ie on their own provide a cohesive meaning ). Thus such attribute needs no additional functional support and as such is self-contained. I'm also well-aware that even with self-contained attributes the custom types may prove beneficial ( for example, they give the ability to add new behavior later, when business requirements change ). Thus, my question focuses only on whether custom types for self-contained attributes really enrich Ubiquitous Language UL a) I've read that in most cases, even simple, self-contained attributes should have custom, more descriptive types rather than basic value types ( double, string ... ), because among other things, descriptive types add to the UL, while the use of basic types instead weakens the language. I understand the importance of UL, but how does having a basic type for a self-contained attribute weaken the language, since with self-contained attributes the name of the attribute already adequately describes the concept and thus contributes to the UL vocabulary? For example, the term person_age already adequately explains the concept of quantifying the number of years a person has: class Person { string person_age; } so what could we possibly gain by also introducing the term ThingAge to the UL: class person { ThingAge person_age; } thanks

• Multilingual sites and Google search results, using sub-folders for language

  - by AWinter

  About three months ago we added an English version of our, previously Japanese only, site under the subfolder /en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> Alternate languages are setup in the sitemap. (as per Google's recommendations) It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? What are the best practices for ensuring that the correct language version of my website is displayed through Google and other search engines? And how long will it take before the new language version becomes prominent in search engine results?

• Help deciding on language for a complex desktop - web application

  - by user967834

  I'm about to start working on a fairly complex project needing a desktop GUI as well as a web interface and I need to decide on a language(s) to use. This is from an electrical engineering/robotics background. These are the requirements: Program will have to read data from multiple sensors and inputs (motion sensor, temperature sensor, capacitive sensor, infrared, magnetic sensors, etc) through a port on a computer - so either through USB or ethernet. Program will have to be able to send control signals based on this input. Program will have to continuously monitor all input signals at all times - so realtime data. Program will require authentication. Program will need to be controllable from a web interface from anywhere via logging in to a website. Web interface will also need to have realtime feedback once authenticated. What language do you think would best accomplish this? I was thinking maybe saving everything into a database which can be accessed by both the desktop and web app? And would Python be able to do all of this? Or something like a remote desktop app? I know this is a complex project but let's assume I can learn any language. Has anyone done something like this and if so how did you accomplish it?

I have been using this command as of now awk '/CVSS Score is/ < /Potential vulnerability found/' output.txt but this seems to display only the name of the vulnerability or the score. How do I display this in file(text,excel) such that all the vulnerability and the corresponding score willbe displayed. Any help would be appreciated Thank you.

• Programming languages, positional languages and natural languages

  - by Vitalij Zadneprovskij

  Some programming languages are modeled on machine code, like assembly languages. Other languages are modeled on a natural language, the English language. Others are not modeled on either machine code or natural language. Languages such as PROLOG, for example, don't follow either model. I came across this Perl module Lingua::Romana::Perligata, that allows to write programs using a syntax that is very similar to Latin. Are there programming languages that have less positional syntax? Are there other languages or modules that allow you to write in syntaxes inspired by other natural languages, like French, Hebrew or Farsi? There is a very long list on Wikipedia, but most of those projects are dead. There is a related question on StackOverflow. The answer that was accepted is "Use Google".

• How should I structure my urls for both SEO and localization?

  - by artlung

  When I set up a site in multiple languages, how should I set up my urls for search engines and usability? Let's say my site is www.example.com, and I'm translating into French and Spanish. What is best for usability and SEO? Directory option: http://www.example.com/sample.html http://www.example.com/fr/sample.html http://www.example.com/es/sample.html Subdomain option: http://www.example.com/sample.html http://fr.example.com/sample.html http://es.example.com/sample.html Filename option: http://www.example.com/sample.html http://www.example.com/sample.fr.html http://www.example.com/sample.es.html Accept-Language header: Or should I simply parse the Accept-Language header and generate content server-side to suit that header? Is there another way to do this? If the different language versions don't have different urls, what do I do about the search engines?
