  • Why Apple’s New SDK Limitation is So Offensive

    - by TStewartDev
    I am not an Apple fanboy, nor have I ever been. However, I have owned a Mac, an iPod, and an iPhone in my lifetime, and for more than a decade, I have defended Apple against the untruths that the haters so enjoy spewing. I encouraged my wife to buy a MacBook when she needed a new laptop two years ago, and I often recommend them to my friends and relatives. I have proudly and happily used my first generation iPhone for nearly three years. Now, for the first time in well over ten years, I find myself ready to swear off Apple and encourage everyone I know to do the same. I was disappointed when Apple wouldn't allow native apps, but I still bought the iPhone. I've stomached their ambiguous app approval process even though it's apparent that Steve may just reject your app because he doesn't like you or feels threatened by you (I'm still lamenting the rejection of the Google Voice app). But, as a developer, I can no longer tolerate Apple's terms and the kind of totalitarian control they indicate Apple wants. In case you are not already familiar, Apple has dictated in their OS 4.0 SDK license agreement (the now infamous Section 3.3.1) that all apps developed for the iPhone must be coded in C, C++, or Objective C, and moreover, that using any cross-compiling platforms is a violation of the agreement. For those of you who aren't developers, let me try to illustrate why this angers those of us who are. Imagine you're a professional writer. You've had articles published in some journals and magazines, and you've got a couple popular books out there, too. You've got an idea for a new book, and so you take it to your publisher. Your publisher agrees that it's a good idea. "But," says the publisher, "we want to hold our books to a tighter standard so that our readers get the experience we want them to have. Therefore, from now on, all our writers may only use words from this list of the 10,000 most common English words. Furthermore, if you cite any other works or quote anyone, they must comply with that same list, or you'll have to rewrite the entire work as well in case our readers want to look up your citation." What do you do? If your work is a children's book, this probably isn't a big deal to you. If it's an autobiography, textbook, or even a novel, though, you're going to have a lot of trouble describing your content with only common words. It's going to take you longer to complete your book, too, since you'll be looking up less common words frequently to see if you can use them. You could always go to another publisher, but this one has the best ability to distribute your book. The next largest distributor can only do a quarter as much. You could abandon the project altogether, but then everyone loses. Isn't this a silly scenario? Who would put such a limitation on writers? Yet this is very much what Apple is doing. They are using their dominant position in the market to coerce developers to write their apps exclusively for the iPhone OS by making it too expensive to write for multiple platforms. It is at least a threefold attack, striking at Adobe who is set to release a compiler that lets Flash source be compiled to iPhone binaries; striking at Google whose Android platform stands the best chance at the moment of providing serious competition to the iPhone; and reinforcing their own strong position by keeping popular apps exclusively to iPhone. And while developers are already very upset about this, the sad fact is that most of us will cave and give in to Apple because consumers don't know any better. They will continue to buy Apple's toy forcing developers to play Apple's maniacal game in order to make any money, at least until Steve Jobs decides he doesn't like them or he intends to release a competing application (bye-bye OpenFeint). Apple has been kept in check on the desktop front by a very dominant Microsoft, but I'm afraid that their success with iPods, iTunes, and iPhones has created a monster that we may have to bear until it is slain by an anti-trust suit or dies with the retirement of Steve Jobs.

English:  It's been a while since the last post... I have been working on machine translation (MT) and post editing (PE) for Japanese.  Last year was my first step in MT+PE area, and I would take this year as an advanced step.  I plan to talk over Post editing 2011 (Advanced Step) on November 27 at JTF Translation Festival.  ?5 days before application due? 21st JTF Translation Festival ? Date:Nov 29, 2011 Tuesday 9:30~20:30(Gate open: 9:00) ? Place:Arcadia Ichigaya Tokyo ? http://www.jtf.jp/jp/festival/festival_top.html In this session, I would like to expand the thought on "how to best utilize MT and PE" either from the view of Client and Translator.  I will show some examples of post editing as a guideline to know what is the best way and most effective way to do post-edit for Japanese.  Also, I will discuss what is the best practice for MT users (Client). The session lasts 90 minutes... sound a little long for me, but I want to spend more time for discussion than last year.  It would be great to exchange thought or experiences about MT and PE.  What is your concerns or problems in the daily work with MT ?  If you have some, please bring them to my session at JTF Translation Festival.  Here is my session details (Japanese): http://www.jtf.jp/jp/festival/festival_program.html#koen_04 Here is the outline of my session: What is the advantage of MT ? Does it solve all the problems about cost, resource, and quality ?  Well, it is not a magic.  So, you cannot expect all at once.  When you have a problem, there are 3 options... 1. Be patient and wait until everything is ready, 2. Run a workaround using anything available now, 3. Find out something completely new and spend time and money. This time, I will focus Option 2 - do something with what we already have.  That is, I will discuss how we can best utilize MT in our daily business.  My view is two ways: From Client point of view, and From Translator point of view Looking forward to meeting many people and exchanging thoughts and information!

  • I am not satisfied with my career and accomplished nothing in my life. what should I do now [on hold]

    - by user2906155
    After my complete my College education I got chance to work on software programming. I work on few software and now nothing make me feel good. I don't like web-programming. Can't have too much mind to play with other people in team a designer or a senior. it's totally time wasting for me. We do integration without any source code control. copy through pen drive. I write in too many language for web-programming but know nothing about any language specially. I don't like to have a BOSS. I would like to do something on my own. From last 3 year I thing I will got a better job but I am unable to get it. I am not good at Programming nor my English is native. I have a big list for pay then my salary. I have problem with nothing. my atmosphere is about illiterate people. they abuse 24 hours a day. this thing make me sick. people watch CRIME patrol my home (watching rape in TV because it's happen to someone). I do my work from home. I don't like to live in my state. All state is one of the biggest illiterate state of my country. Once I apply for a Job in China and it's look like I can get thing Job but I don't get it. My family doesn't want me to settle anywhere else. I told my family 4 time a day that I can't live in this worst situation. Everyone (including the person who I work for) tell me that you can do it only you have money. Now I really don't know how to make money. My job not allow me to work for anyone. My productivity going down since I don't learn anything new. I thing if this happen to me for next 2 year I don't have any knowledge more then a peon. I hate it. When I was in other city then I see that if I spent 7 days their all my 7 days going better. even I go for travelling in green places then I like it. but all I hate it where I work for. When I work on other city then I see my productivity are improved and I don't hate my work. I listen a song "If you don't your love what are you doing it for". I seriously don' t know what I still live here because this place gave me nothing but depression and trouble. for people I clear that I don't belong to RICH or middle class family. All I got is doing something on my own or help of someone. affording a rental place make my run on footpath. All I save in one month is just 10$ (approximately) (actually I afford some guys's education now). Can a programmer live worst life like this. I really not happy. Today is a festival in India and I don't celebrate it because I really hate myself. I want to do suicide. someone guide me how to start solving this headache

  • Windows 7 UAC manifest file for some VB6 application

    - by Daniel
    Hi, all, I have an old VB6 application which should run on Windows 7 (with UAV set to the default level, 3 of 4 IMHO). It has the functionality to update itself, and Windows 7 is now complaining that it would modify the computer (At least windows 7 is right here). I was able to run it in Vista with some kind of manifest file, but this does not seem to work anymore (which is the intended behaviour if I think of it). The manifest file is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.1.0.24" processorArchitecture="X86" name="IKOfficeAppStarter" type="win32"/> <description>IKOffice Starter</description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*"/> </dependentAssembly> </dependency> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="true"/> </requestedPrivileges> </security> </trustInfo> </assembly> The manifest can be found near the exe "IKOffice Starter.exe" and is called "IKOffice Starter.exe.manifest", which should be okey. Currently the Shield Icon has gone from my .exe, but when try to start the software, i get the message "Der angeforderte Vorgang erfordert höhere Rechte", or translated to english "the requested operation requires elevation". What can I do to stop windows to bug me anymore, so I can install this application on our clients computers. Hey, I already told Windows to run it as Invoker, so why is it still complaining?

  • WPF WriteableBitmap Memory Leak?

    - by Mario
    Hello, everyone! I'm trying to figure out how to release a WriteableBitmap memory. In the next section of code I fill the backbuffer of a WriteableBitmap with a really large amount of data from "BigImage" (3600 * 4800 px, just for testing) If I comment the lines where bitmap and image are equaled to null, the memory it´s not release and the application consumes ~230 MB, even when Image and bitmap are no longer used! As you can see at the end of the code its necessary to call GC.Collect() to release the memory. So the question is, what is the right way to free the memory used by a WriteableBitmap object? Is GC.Collect() the only way? Any help would be great. PS. Sorry for my bad english. private void buttonTest_Click(object sender, RoutedEventArgs e) { Image image = new Image(); image.Source = new BitmapImage(new Uri("BigImage")); WriteableBitmap bitmap = new WriteableBitmap( (BitmapSource)image.Source); bitmap.Lock(); // Bitmap processing bitmap.Unlock(); image = null; bitmap = null; GC.Collect(); }

  • How to retrieve value from DropDownListFor html helper in ASP>NET MVC2?

    - by Eedoh
    Hello I know there was few similar questions here about DropDownListFor, but neither helped me... I use Entity Framework as ORM in my project. There's EF model called "Stete". Stete has Foreign on EF model called "Drustva" Now I'm trying to make a form for editing the data, for Stete model. I managed to display everything, including Stete.Drustva.Naziv property, but I can't get this last property in my handler method [HttpPost]. It always return 0, no matter what I select in drop down list. Here's the code: DrustvaController: public static IEnumerable<SelectListItem> DrustvaToSelectListItemsById(this KnjigaStetnikaEntities pEntities, int Id) { IEnumerable<Drustva> drustva = (from d in pEntities.Drustva select d).ToList(); return drustva.OrderBy(drustvo => drustvo.Naziv).Select(drustvo => new SelectListItem { Text = drustvo.Naziv, Value = drustvo.Id.ToString(), Selected = (drustvo.Id == Id)? true : false }); } SteteController: private IEnumerable<SelectListItem> privremenaListaDrustava(int Id) { using (var ctx = new KnjigaStetnikaEntities()) { return ctx.DrustvaToSelectListItemsById(Id); } } public ActionResult IzmijeniPodatkeStete(Int32 pBrojStete) { PretragaStetaModel psm = new PretragaStetaModel(); ViewData["drustva"] = privremenaListaDrustava(psm.VratiStetuPoBrojuStete(pBrojStete).Drustva.Id); ViewData.Model = new Models.Stete(); return View("EditView", (Stete.Models.Stete)psm.GetSteta(pBrojStete)); } EditView: <div class="editor-label"> <%: Html.Label("Društvo") %> </div> <div class="editor-field"> <%: Html.DropDownListFor(m => m.Drustva.Naziv, ViewData["drustva"] as IEnumerable<SelectListItem>) %> <%: Html.ValidationMessageFor(model => model.FKDrustvo) %> </div> I am sorry for not translating names of the objects into english, but they hardly have appropriate translation. If necessary, I can try creating similar example...

  • C# - Fill a combo box with a DataTable

    - by MrG
    I'm used to work with Java where large amounts of examples are available. For various reasons I had to switch to C# and trying to do the following in SharpDevelop: // Form has a menu containing a combobox added via SharpDevelop's GUI // --- Variables languages = new string[2]; languages[0] = "English"; languages[1] = "German"; DataSet myDataSet = new DataSet(); // --- Preparation DataTable lTable = new DataTable("Lang"); DataColumn lName = new DataColumn("Language", typeof(string)); lTable.Columns.Add( lName ); for( int i=0; i<languages.Length; i++ ) { DataRow lLang = lTable.NewRow(); lLang["Language"] = languages[i]; lTable.Rows.Add(lLang); } myDataSet.Tables.Add(lTable); // --- Handling the combobox mnuActionLanguage.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView; mnuActionLanguage.ComboBox.DisplayMember = "Language"; One would assume to see some values in the dropdown, but it's empty. Please tell me what I'm doing wrong ;( EDIT: mnuActionLanguage.ComboBox.DataBind() is what I also found on the net, but it doesn't work in my case. SOLUTION mnuActionLanguage.ComboBox.BindingContext = this.BindingContext; at the end solved the problem!

  • SharePoint: Can't Connect to a Configuration Database When Using Configuration Wizard

    - by Denis
    Hello everyone. I wonder if you could help me with the following problem: We have a SharePoint farm consisted of two servers with an NLB (a load balancer), a database server and an index server (4 servers in total). The issues initially appeared when we were trying to change Search settings via Shared services provider and an error was appearing with the message I can’t even remember now. To fix that problem, we decided to restart Search services on the Index server via Central Administration… and the process had stuck with a status “stopping” for several days. We’ve found a few solutions on the forums, but nothing had helped. Then we’ve tried to exclude the Index server from the farm, but yet again, Search services would not stop. However, after a week we’ve noticed that the services finally stopped. That was a prologue. So, after the Search services have finally stopped, we decided to return the Index server back to the farm via the SharePoint Configuration wizard. When we click on a button “Search database instances” (don’t know the exact name in English, we have a Russian version), a correct database name and user are automatically appear in the relevant fields. Then we supply a password for the user and click “next” two times and the configuration begins. Unfortunately, at the second stage we receive the error “Could not connect to a configuration database” with the exception in the log file: “Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.” Now we can’t figure out why the configuration wizard can’t connect to the configuration database. Any suggestions will be really appreciated.

  • Confused about C++'s std::wstring, UTF-16, UTF-8 and displaying strings in a windows GUI

    - by dfrey
    I'm working on a english only C++ program for Windows where we were told "always use std::wstring", but it seems like nobody on the team really has much of an understanding beyond that. I already read the question titled "std::wstring VS std::string. It was very helpful, but I still don't quite understand how to apply all of that information to my problem. The program I'm working on displays data in a Windows GUI. That data is persisted as XML. We often transform that XML using XSLT into HTML or XSL:FO for reporting purposes. My feeling based on what I have read is that the HTML should be encoded as UTF-8. I know very little about GUI development, but the little bit I have read indicates that the GUI stuff is all based on UTF-16 encoded strings. I'm trying to understand where this leaves me. Say we decide that all of our persisted data should be UTF-8 encoded XML. Does this mean that in order to display persisted data in a UI component, I should really be performing some sort of explicit UTF-8 to UTF-16 transcoding process? I suspect my explanation could use clarification, so I'll try to provide that if you have any questions.

  • How to get Processor and Motherboard Id ?

    - by Frank
    I use the code from http://www.rgagnon.com/javadetails/java-0580.html to get Motherboard Id, but the result is "null", <1 How can that be ? <2 Also I modified the code a bit to look like this to get processor Id : "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"+ "Set colItems = objWMIService.ExecQuery _ \n"+ " (\"Select * from Win32_Processor\") \n"+ "For Each objItem in colItems \n"+ " Wscript.Echo objItem.ProcessorId \n"+ " exit for ' do the first cpu only! \n"+ "Next \n"; The result is something like : ProcessorId = BFEBFBFF00010676 On http://msdn.microsoft.com/en-us/library/aa389273%28VS.85%29.aspx it says : ProcessorId : Processor information that describes the processor features. For an x86 class CPU, the field format depends on the processor support of the CPUID instruction. If the instruction is supported, the property contains 2 (two) DWORD formatted values. The first is an offset of 08h-0Bh, which is the EAX value that a CPUID instruction returns with input EAX set to 1. The second is an offset of 0Ch-0Fh, which is the EDX value that the instruction returns. Only the first two bytes of the property are significant and contain the contents of the DX register at CPU reset—all others are set to 0 (zero), and the contents are in DWORD format. I don't quite understand it, in plain English, is it unique or just a number for this class of processors, for instance all Intel Core2 Duo P8400 will have this number ? Frank

  • Schliemann's method of programming language learning

    - by DVK
    Background: 19th-century German archeologist Heinrich Schliemann was of course famous for his successful quest to find and excavate the city of Troy (an actual archeological site for the Troy of Homer's Iliad). However, he is just as famous for being an astonishing learner of languages - within the space of two years, he taught himself fluent Dutch, English, French, Spanish, Italian and Portuguese, and later went on to learn seven more, including both modern and ancient Greek. One of the methods he famously used was comparison of a known text, e.g. take a book in a language one is fluent in, take a good translation of a book in a language you wish to learn, and go over them in parallel. (various sources cited the book used by Schliemann to be the Bible, or, as the link above states, a novel). Now, for the actual question. Has anyone used (or heard of) an equivalent of Schliemann's method for learning a new programming language? E.g. instead of basing the leaning on references and tutorials, take a somewhat comprehensive set of programs known to have high-quality code in both languages implementing similar/identical algorithms and learn by comparing them? I'm curious about either personal experiences of applying such an approach, or references to something published, or existance of codebases which could be used for such an approach? What got me thinking about the idea was Project Euler and some code snippets I saw on SO, in C++, Perl and Lisp.

  • "Parameter type conflict" when calling Java Stored Procedure within another Java Stored Procedure

So, the error message I'm getting is: 'parameter type conflict'... the function "FC_RJS_INCLUIR_RELACAO_PRODCAT" it's a Java Stored Procedure too, it's already exported to Oracle, and returns an int variable, and i have to read this to decide which webservice i will call from this JavaSP. I have already tried the OracleTyep.NUMBER in the registerOutParameter. Anyone knows what i'm doing wrong?

  • Need help understanding "TypeError: default __new__ takes no parameters" error in python

    - by Gordon Fontenot
    For some reason I am having trouble getting my head around __init__ and __new__. I have a bunch of code that runs fine from the terminal, but when I load it as a plugin for Google Quick Search Box, I get the error TypeError: default __new__ takes no parameters. I have been reading about the error, and it's kind of making my brain spin. As it stands I have 3 classes, with no sub-classes, each class has it's own defs. I never use def __init__ or def __new__, but I have gotten the distinct feeling that these are the functions (or the lack thereof) that would be giving me the error. I have no idea how to summarize the code down to a snippet that would be helpful here, since I'm a bit over my head, but the entire script can be found at github. Not expecting anyone to bugfix my code for me, I am just at my wit's end on this. A simple (plain english, not the quote from the python docs which I have read 20 times and still don't really understand) explination of why this error would pop up, or why I should be, or not be, using the __init__ and/or __new__ functions would be seriously appreciated. Thanks for any help you can give in advance.

  • Any Other Ideas for prototyping..

    - by davehamptonusa
    I've used Douglass Crockford's Object.beget, but augmented it slightly to: Object.spawn = function (o, spec) { var F = function () {}, that = {}, node = {}; F.prototype = o; that = new F(); for (node in spec) { if (spec.hasOwnProperty(node)) { that[node] = spec[node]; } } return that; }; This way you can "beget" and augment in one fell swoop. var fop = Object.spawn(bar, { a: 'fast', b: 'prototyping' }); In English that means, "Make me a new object called 'fop' with 'bar' as its prototype, but change or add the members 'a' and 'b'. You can even nest it the spec to prototype deeper elements, should you choose. var fop = Object.spawn(bar, { a: 'fast', b: Object.spawn(quux,{ farple: 'deep' }), c: 'prototyping' }); This can help avoid hopping into an object's prototype unintentionally in a long object name like: foo.bar.quux.peanut = 'farple'; If quux is part of the prototype and not foo's own object, your change to 'peanut' will actually change the protoype, affecting all objects prototyped by foo's prototype object. But I digress... My question is this. Because your spec can itself be another object and that object could itself have properties from it's prototype in your new object - and you may want those properties...(at least you should be aware of them before you decided to use it as a spec)... I want to be able to grab all of the elements from all of the spec's prototype chain, except for the prototype object itself... This would flatten them into the new object. Should I use: Object.spawn = function (o, spec) { var F = function () {}, that = {}, node = {}; F.prototype = o; that = new F(); for (node in spec) { that[node] = spec[node]; } that.prototype = o; return that; }; I would love thoughts and suggestions...

  • Weird RecordStore behavior when RecordStoreFullException occurs

    - by Michael P
    Hello everyone! I'm developing a small J2ME application that displays bus stops timetables - they are stored as records in MIDP RecordStores. Sometimes records can not fit a single RecordStore, especially on record update - using setRecord method - a RecordStoreFullException occurs. I catch the exception, and try to write the record to a new RecordStore along with deleting the previous one in the old RecordStore. Everything works fine except of deleting record from RecordStore where the RecordStoreFullException occurs. If I make an attempt to delete record that could not be updated, another Exception of type InvalidRecordIDException is thrown. This is weird and undocumented in MIDP javadoc. I have tested it on Sun WTK 2.5.2, MicroEdition SDK 3.0 and Nokia Series 40 SDK. Furthermore I created a code that reproduces this strange behaviour: RecordStore rms = null; int id = 0; try { rms = RecordStore.openRecordStore("Test", true); byte[] raw = new byte[192*10024]; //Big enough to cause RecordStoreFullException id = rms.addRecord(raw, 0, 160); rms.setRecord(id, raw, 0, raw.length); } catch (Exception e) { try { int count = rms.getNumRecords(); RecordEnumeration en = rms.enumerateRecords(null, null, true); count = en.numRecords(); while(en.hasNextElement()){ System.out.println("NextID: "+en.nextRecordId()); } rms.deleteRecord(id); //this won't work! rms.setRecord(id, new byte[5], 0, 5); //this won't work too! } catch (Exception ex) { ex.printStackTrace(); } } I added extra enumeration code to produce other weird behavior - when RecordStoreFullException occurs, count variable will be set to 1 (if RMS was empty) by both methods - getNumRecords and numRecords. System.out.println will produce NextID: 0! It is not acceptable because record ID can not be 0! Could someone explain this strange behavior? Sorry for my bad English.

  • Using Java PDFBox library to write Russian PDF

    - by Brad
    I am using a Java library called PDFBox trying to write text to a PDF. It works perfect for English text, but when i tried to write Russian text inside the PDF the letters appeared so strange. It seems the problem is in the font used, but i am not so sure about that, so i hope if anyone could guide me through this. Here is the important code lines : PDTrueTypeFont font = PDTrueTypeFont.loadTTF( pdfFile, new File( "fonts/VREMACCI.TTF" ) ); // Windows Russian font imported to write the Russian text. font.setEncoding( new WinAnsiEncoding() ); // Define the Encoding used in writing. // Some code here to open the PDF & define a new page. contentStream.drawString( "??????? ????????????" ); // Write the Russian text. The WinAnsiEncoding source code is : Click here --------------------- Edit on 18 November 2009 After some investigation, i am now sure it is an Encoding problem, this could be solved by defining my own Encoding using the helpful PDFBox class called DictionaryEncoding. I am not sure how to use it, but here is what i have tried until now : COSDictionary cosDic = new COSDictionary(); cosDic.setString( COSName.getPDFName("Ercyrillic"), "0420 " ); // Russian letter. font.setEncoding( new DictionaryEncoding( cosDic ) ); This does not work, as it seems i am filling the dictionary in a wrong way, when i write a PDF page using this it appears blank. The DictionaryEncoding source code is : Click here Thanks . . .

  • Good locations worldwide for a coder gypsy wannabe

    - by fung
    Yes, this is not programming related but please bear with me =). I run a small niche SaaS business. Lately I've been thinking of traveling and experiencing life in other places. Would really appreciate suggestions for good places a developer could relocate to. In particular I'm looking for a place that: Has good internet connection (cheap stable broadband, lots of places that provide free wifi, etc.) Low cost of living (rent and food fairly cheap). At least half of the population speak English. Has a local courier agent (DHL, Fedex, any...). The government allows for extended stay of foreigners. I'm thinking of staying for about 6 months at each location and maybe doing it for 3 years. So looking for 5 to 6 locations in total. So if any of you think you're staying in a place that would be great for a visiting developer then please shout out. Include as detailed a description as possible. And include any cons about the place if there are. The only place that pops to mind right now is Bali =). Isle of Skye also seems interesting but I think immigration is tight and cost of living would definitely be higher. Thanks in advance for suggestions =)

  • FLEX/BISON : Why my rule is not regonized ?

  • How to create this MongoMapper custom data type?

    - by Kapslok
    I'm trying to create a custom MongoMapper data type in RoR 2.3.5 called Translatable: class Translatable < String def initialize(translation, culture="en") end def languages end def has_translation(culture)? end def self.to_mongo(value) end def self.from_mongo(value) end end I want to be able to use it like this: class Page include MongoMapper::Document key :title, Translatable, :required => true key :content, String end Then implement like this: p = Page.new p.title = "Hello" p.title(:fr) = "Bonjour" p.title(:es) = "Hola" p.content = "Some content here" p.save p = Page.first p.languages => [:en, :fr, :es] p.has_translation(:fr) => true en = p.title => "Hello" en = p.title(:en) => "Hello" fr = p.title(:fr) => "Bonjour" es = p.title(:es) => "Hola" In mongoDB I imagine the information would be stored like: { "_id" : ObjectId("4b98cd7803bca46ca6000002"), "title" : { "en" : "Hello", "fr" : "Bonjour", "es" : "Hola" }, "content" : "Some content here" } So Page.title is a string that defaults to English (:en) when culture is not specified. I would really appreciate any help.

  • WCF selfhosted service, installer class and netsh

    - by jeho
    I have a selfhosted WCF service application which I want to deploy by a msi installer package. The endpoint uses http port 8888. In order to startup the project under windows 2008 after installation I have to either run the program as administrator or have to edit the http settings with netsh: "netsh http add urlacl url=http://+:8888/ user=\Everyone" I want to edit the http settings from my installer class. Therefore I call the following method from the Install() method: public void ModifyHttpSettings() { string parameter = @"http add urlacl url=http://+:8888/ user=\Everyone"; System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("netsh", parameter); psi.Verb = "runas"; psi.RedirectStandardOutput = false; psi.CreateNoWindow = true; psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; psi.UseShellExecute = false; System.Diagnostics.Process.Start(psi); } This method will work for english versions of windows, but not for localized versions (The group Everyone has different names in localized versions). I have also tried to use Environment.UserName to allow access at least for the current logged on user. But this does also not work, because the installer class is run by the msi service which runs under the user SYSTEM. Hence Enviroment.UserName returns SYSTEM and that is not what I want. Is there a way to grant access to all (or at least for the current logged on) user to my selfhosted WCF service from a msi installer class?

  • PHP4 including file during session

    - by Matherw
    I am trying to put second language on my webpage. I decided to use different files for different languages told apart by path - language/pl/projects.ln contains Polish text, language/en/projects.ln - English. Those extensions are just to tell language files from other, the content is simple php: $lang["desc"]["fabrics"]["title"] = "MATERIALY"; $lang["desc"]["fabrics"]["short_text"] = "Jakis tam tekst na temat materialów"; $lang["desc"]["services"]["title"] = "USLUGI"; $lang["desc"]["services"]["short_text"] = "Jakis tam tekst na temat uslóg"; And then on the index page I use it like so: session_start(); if (isset($_SESSION["lang"])) { $language = $_SESSION["lang"]; } else { $language = "pl"; } include_once("language/$language/projects.ln"); print $lang["desc"]["fabrics"]["title"]; The problem is that if the session variable is not set everything works fine and array item content is displayed but once I change and set $_SESSION["lang"] nothing is displayed. I tested if the include itself works as it should by putting print "sth"; at the beginning of projects.ln file and that works all right both with $_SESSION["lang"] set and unset. Please help.

  • UML class diagram vs ER database diagram

    - by salva84
    Hi, I'm a little confused, I'm developing a program, the program consist in two parts, the server and the clients, there are groups, places, messages... stored in the server, and the clients has to connect with it. I've design the use cases diagram, the activity diagrams, and I have design the class diagram too. The thing is that I want to implement the server in a mysql tables for storing the users, groups, places... users in groups... so I've designed a E-R diagram consisting in 6 tables, but the problem is that I think that my class diagram and my ER diagram looks too similar, I mean, I think I'm not doing things right because I have a class for each table practically, and when I have to extract all the users on my system, do I have to convert all the rows into objects at first and write in the database for each object modified? The easy choice for me would be to base my whole application only in the database, and making a class to extract and insert data in it, but I have to follow the UML specification and I'm a little confused what to do with the class diagram, because the books I have read say that I have to create a class for each "entity" of my program. Sorry for my bad English. Thank you.
