  • Language in a Sandbox in Rails

    - by Jon Romero
    I've found that there WAS a sandbox gem (created by the guys that made try ruby in your browser but it was compatible only with Ruby 1.8. Another problem is that I cannot find it anymore (it seems they stop serving the gem from the servers...). So, is there any secure way of running ruby in a sandbox (so you can run it from your browser)? Or an easy way to run (for example lua/python) in a sandbox (no filesystem access, no creation of objects etc) and be called from Ruby (Rails 2.2)? I want to make an application like try_ruby even without having a ruby underneath. But it has to be an easy language (I saw there was a prolog in ruby, even a lisp but I don't think they are easy to learn languages...). So, do you have any suggestions or tips? Or should I just start creating my own DSL in Ruby (if there is a solution in creating a somewhat safe system)? Thx

  • sqlite with Perl for Windows; suitable for relocation

    - by Paul Nathan
    I need to set up sqllite for Perl on a Windows box. However - Perl is probably being run over the network from a central server, and I do not know what modules will be available on initial running of my script. I can guarantee Perl 5.8+ (activestate) or Perl 5.10+ (strawberry). Therefore, I need to package sqlite & the associated Perl module(s) in the project directory itself. Having Goggled around, I don't see any immediate zipfile to do this.

  • IIS 6/.Net 2:How can user A get the user cookie for unrelated user B who is in a different session a

    - by jon.ediger
    1) user A goes to the site, creates an account, and logs in 2) user b goes to the site. Rather than having to log in, user b enters as though user b is user a. User b gets access to all of user a's data and can brows the site as user a. Note: user b does not log in. User b just hits the site, and the site returns as if user b is already logged in as user a. Note 2: user a and user b are on distinct computers. Also, static variables are not involved in the code. Setup: IIS 6 .Net 2.0 OutputCache off for the pages in the site

  • VC7.1 C1204 internal compiler error

    - by Nathan Ernst
    I'm working on modifying Firaxis' Civilization 4 core game DLL. The host application is built using VC7, hence the constraint (source not provided for the host EXE). I've been working on rewriting a large chunk of the code (focusing on low-hanging performance issues & memory leaks). I recently ran into an internal compiler error when trying to mod the code to use an array class instead of dynamically allocated 2-d arrays, I was going to use matrices from the boost lib (Civ4 is already using boost, so why not?). Basically, the issue comes down to: if I include "boost/numeric/ublas/matrix.hpp", I run into an internal compiler error C1204. MSDN has this to say: MSDN C1204 KB has this to say: KB 883655 So, I'm curious, is it possible to solve this error without a KB/SP being applied and dramatically reducing the complexity of the code? Additionally, as VC7 is no longer "supported", does anyone have a valid (supported) link for a VC7 service pack?

  • No Binary File Generation

    I've just bought a new laptop for me on the travel, then on my free time, I've started to test MinGW on it by trying to compile my own OS that is written in C++, then I've created all the files needed and the kernel.cpp: extern "C" void _main(struct multiboot_data* mbd, unsigned int magic); void _main( struct multiboot_data* mbd, unsigned int magic ) { char * boot_loader_name =(char*) ((long*)mbd)[16]; /* Print a letter to screen to see everything is working: */ unsigned char *videoram = (unsigned char *) 0xb8000; videoram[0] = 65; /* character 'A' */ videoram[1] = 0x07; /* forground, background color. */ } And tried to compile it with g++ G: g++ -o C:\kernel.o -c kernel.cpp -Wall -Wextra -Werror -nostdlib -nostartfiles -nodefaultlibs kernel.cpp: In function `void _main(multiboot_data*, unsigned int)': kernel.cpp:8: warning: unused variable 'boot_loader_name' kernel.cpp: At global scope: kernel.cpp:4: warning: unused parameter 'magic' G: But it don't create any binary file at C:/, what can I do?

  • Infopath 2007 and WCF Data Connection

    - by Nathan Fisher
    I am having trouble trying to connect an Infopath 2007 form to an WCF web service. I appears that the Infopath only wants to communicate via a SOAP 1.0 message. To get around the issue for the moment I have created an .asmx web service. Should I consider continuing down this workaround or figure out a way to get WCF to dish out SOAP 1.0 1.1 messages?

  • SQLite Modify Column

    - by Nathan
    I need to modify a column in a SQLite database but I have to do it programatically due to the database already being in production. From my research I have found that in order to do this I must do the following. Create a new table with new schema Copy data from old table to new table Drop old table Rename new table to old tables name That seems like a ridiculous amount of work for something that should be relatively easy. Is there not an easier way? All I need to do is change a constraint on a existing column and give it a default value.

  • PNGException "crc corruption" when attempting to create ImageIcon objects from ZIP archive

    - by Nathan Strong
    I've got a ZIP file containing a number of PNG images that I am trying to load into my Java application as ImageIcon resources directly from the archive. Here's my code: import java.io.*; import java.util.Enumeration; import java.util.zip.*; import javax.swing.ImageIcon; public class Test { public static void main( String[] args ) { if( args.length == 0 ) { System.out.println("usage: java Test.java file.zip"); return; } File archive = new File( args[0] ); if( !archive.exists() || !archive.canRead() ) { System.err.printf("Unable to find/access %s.\n", archive); return; } try { ZipFile zip = new ZipFile(archive); Enumeration <? extends ZipEntry>e = zip.entries(); while( e.hasMoreElements() ) { ZipEntry entry = (ZipEntry) e.nextElement(); int size = (int) entry.getSize(); int count = (size % 1024 == 0) ? size / 1024 : (size / 1024)+1; int offset = 0; int nread, toRead; byte[] buffer = new byte[size]; for( int i = 0; i < count; i++ ) { offset = 1024*i; toRead = (size-offset > 1024) ? 1024 : size-offset; nread = zip.getInputStream(entry).read(buffer, offset, toRead); } ImageIcon icon = new ImageIcon(buffer); // boom -- why? } zip.close(); } catch( IOException ex ) { System.err.println(ex.getMessage()); } } } The sizes reported by entry.getSize() match the uncompressed size of the PNG files, and I am able to read the data out of the archive without any exceptions, but the creation of the ImageIcon blows up.

  • Video Synthesis - Making waves, pattern, gradients...

    - by Nathan
    I'm writing a program to generate some trippy visuals. My code paints each pixel with a random blue value which loops at 0.04 second intervals. for (y = 0; y < 5.5; y += 0.2) { for (x = 0; x < 7.5; x += 0.2) { b = rand() / ((double) RAND_MAX); setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise... but my maths is a bit rusty, and Google isn't helping me much today, so it would be great if you could share anything you know about making waves, patterns, gradient animations, etc or links to such material.

  • Arguments On a Console eMbedded Visual C++ Application

    - by Nathan Campos
    I'm trying to develop a simple application that will read some files, targeted for Windows CE. For this I'm using Microsoft eMbedded Visual C++ 3. This program(that is for console) will be called like this: /Storage Card/Test coms file.cmss As you can see, file.cmss is the first argument, but on my main I have a condition to show the help(the normal, how to use the program) if the arguments are smaller than 2: if(argc < 2) { showhelp(); return 0; } But when I execute the program on the command-line of Windows CE(using all the necessary arguments) I got the showHelp() content. Then I've checked all the code, but it's entirelly correct. But I think that eVC++ don't use argc and argv[] for arguments, then I want some help on how to determine the arguments on it.

  • Reading Source Code Aloud

    - by Jon Purdy
    After seeing this question, I got to thinking about the various challenges that blind programmers face, and how some of them are applicable even to sighted programmers. Particularly, the problem of reading source code aloud gives me pause. I have been programming for most of my life, and I frequently tutor fellow students in programming, most often in C++ or Java. It is uniquely aggravating to try to verbally convey the essential syntax of a C++ expression. The speaker must give either an idiomatic translation into English, or a full specification of the code in verbal longhand, using explicit yet slow terms such as "opening parenthesis", "bitwise and", et cetera. Neither of these solutions is optimal. On the one hand, an idiomatic translation is only useful to a programmer who can de-translate back into the relevant programming code—which is not usually the case when tutoring a student. In turn, education (or simply getting someone up to speed on a project) is the most common situation in which source is read aloud, and there is a very small margin for error. On the other hand, a literal specification is aggravatingly slow. It takes far far longer to say "pound, include, left angle bracket, iostream, right angle bracket, newline" than it does to simply type #include <iostream>. Indeed, most experienced C++ programmers would read this merely as "include iostream", but again, inexperienced programmers abound and literal specifications are sometimes necessary. So I've had an idea for a potential solution to this problem. In C++, there is a finite set of keywords—63—and operators—54, discounting named operators and treating compound assignment operators and prefix versus postfix auto-increment and decrement as distinct. There are just a few types of literal, a similar number of grouping symbols, and the semicolon. Unless I'm utterly mistaken, that's about it. So would it not then be feasible to simply ascribe a concise, unique pronunciation to each of these distinct concepts (including one for whitespace, where it is required) and go from there? Programming languages are far more regular than natural languages, so the pronunciation could be standardised. Speakers of any language would be able to verbally convey C++ code, and due to the regularity and fixity of the language, speech-to-text software could be optimised to accept C++ speech with a high degree of accuracy. So my question is twofold: first, is my solution feasible; and second, does anyone else have other potential solutions? I intend to take suggestions from here and use them to produce a formal paper with an example implementation of my solution.

  • Match entities fulfilling filter (strict superset of search)

    - by Jon
    I have an entity (let's say Person) with a set of arbitrary attributes with a known subset of values. I need to search for all of these entities that match all my filter conditions. That is, given a set of Attributes A, I need to find all people that have a set of Attributes that are a superset of A. For example, my table structures look like this: Person: id | name 1 | John Doe 2 | Jane Roe 3 | John Smith Attribute: id | attr_name 1 | Sex 2 | Eye Color ValidValue: id | attr_id | value_name 1 | 1 | Male 2 | 1 | Female 3 | 2 | Blue 4 | 2 | Green 5 | 2 | Brown PersonAttributes id | person_id | attr_id | value_id 1 | 1 | 1 | 1 2 | 1 | 2 | 3 3 | 2 | 1 | 2 4 | 2 | 2 | 4 5 | 3 | 1 | 1 6 | 3 | 2 | 4 In JPA, I have entities built for all of these tables. What I'd like to do is perform a search for all entities matching a given set of attribute-value pairs. For instance, I'd like to be able to find all males (John Doe and John Smith), all people with green eyes (Jane Roe or John Smith), or all females with green eyes (Jane Roe). I see that I can already take advantage of the fact that I only really need to match on value_id, since that's already unique and tied to the attr_id. But where can I go from there? I've been trying to do something like the following, given that the ValidValue is unique in all cases: select distinct p from Person p join p.personAttributes a where a.value IN (:values) Then I've tried putting my set of required values in as "values", but that gives me errors no matter how I try to structure that. I also have to get a little more complicated, as follows, but at this point I'd be happy with solving the first problem cleanly. However, if it's possible, the Attribute table actually has a field for default value: id | attr_name | default_value 1 | Sex | 1 2 | Eye Color | 5 If the value you're searching on happens to be the default value, I want it to return any people that have no explicit value set for that attribute, because in the application logic, that means they inherit the default value. Again, I'm more concerned about the primary question, but if someone who can help with that also has some idea of how to do this one, I'd be extremely grateful.

  • How can I force asp.net webapi to always decode POST data as JSON

    - by Nathan Reed
    I getting some json data posted to my asp.net webapi, but the post parameter is always coming up null - the data is not being serialized correctly. The method looks something like this: public HttpResponseMessage Post(string id, RegistrationData registerData) It seems the problem is that the client (which I have no control over) is always sending the content-type as x-www-form-urlencoded, even though the content is actually json. This causes mvc to try to deserialize as form data, which fails. Is there anyway to get webapi to always deserialize as json, and to ignore the content-type header?

  • How to make a custom NSFormatter work correctly on Snow Leopard?

    - by Nathan
    I have a custom NSFormatter attached to several NSTextFields who's only purpose is to uppercase the characters as they are typed into field. The entire code for my formatter is included below. The stringForObjectValue() and getObjectValue() implementations are no-ops and taken pretty much directly out of Apple's documentation. I'm using the isPartialStringValid() method to return an uppercase version of the string. This code works correctly in 10.4 and 10.5. When I run it on 10.6, I get "strange" behaviour where text fields aren't always render the characters that are typed and sometimes are just displaying garbage. I've tried enabling NSZombie detection and running under Instruments but nothing was reported. I see errors like the following in "Console": HIToolbox: ignoring exception '*** -[NSCFString replaceCharactersInRange:withString:]: Range or index out of bounds' that raised inside Carbon event dispatch ( 0 CoreFoundation 0x917ca58a __raiseError + 410 1 libobjc.A.dylib 0x94581f49 objc_exception_throw + 56 2 CoreFoundation 0x917ca2b8 +[NSException raise:format:arguments:] + 136 3 CoreFoundation 0x917ca22a +[NSException raise:format:] + 58 4 Foundation 0x9140f528 mutateError + 218 5 AppKit 0x9563803a -[NSCell textView:shouldChangeTextInRange:replacementString:] + 852 6 AppKit 0x95636cf1 -[NSTextView(NSSharing) shouldChangeTextInRanges:replacementStrings:] + 1276 7 AppKit 0x95635704 -[NSTextView insertText:replacementRange:] + 667 8 AppKit 0x956333bb -[NSTextInputContext handleTSMEvent:] + 2657 9 AppKit 0x95632949 _NSTSMEventHandler + 209 10 HIToolbox 0x93379129 _ZL23DispatchEventToHandlersP14EventTargetRecP14OpaqueEventRefP14HandlerCallRec + 1567 11 HIToolbox 0x933783f0 _ZL30SendEventToEventTargetInternalP14OpaqueEventRefP20OpaqueEventTargetRefP14HandlerCallRec + 411 12 HIToolbox 0x9339aa81 SendEventToEventTarget + 52 13 HIToolbox 0x933fc952 SendTSMEvent + 82 14 HIToolbox 0x933fc2cf SendUnicodeTextAEToUnicodeDoc + 700 15 HIToolbox 0x933fbed9 TSMKeyEvent + 998 16 HIToolbox 0x933ecede TSMProcessRawKeyEvent + 2515 17 AppKit 0x95632228 -[NSTextInputContext handleEvent:] + 1453 18 AppKit 0x9562e088 -[NSView interpretKeyEvents:] + 209 19 AppKit 0x95631b45 -[NSTextView keyDown:] + 751 20 AppKit 0x95563194 -[NSWindow sendEvent:] + 5757 21 AppKit 0x9547bceb -[NSApplication sendEvent:] + 6431 22 AppKit 0x9540f6fb -[NSApplication run] + 917 23 AppKit 0x95407735 NSApplicationMain + 574 24 macsetup 0x00001f9f main + 24 25 macsetup 0x00001b75 start + 53 ) Can anybody shed some light on what is happening?

  • Mutating the expression tree of a predicate to target another type

    - by Jon
    Intro In the application I 'm currently working on, there are two kinds of each business object: the "ActiveRecord" type, and the "DataContract" type. So for example, we have: namespace ActiveRecord { class Widget { public int Id { get; set; } } } namespace DataContracts { class Widget { public int Id { get; set; } } } The database access layer takes care of "translating" between hierarchies: you can tell it to update a DataContracts.Widget, and it will magically create an ActiveRecord.Widget with the same property values and save that. The problem I have surfaced when attempting to refactor this database access layer. The Problem I want to add methods like the following to the database access layer: // Widget is DataContract.Widget interface DbAccessLayer { IEnumerable<Widget> GetMany(Expression<Func<Widget, bool>> predicate); } The above is a simple general-use "get" method with custom predicate. The only point of interest is that I 'm not passing in an anonymous function but rather an expression tree. This is done because inside DbAccessLayer we have to query ActiveRecord.Widget efficiently (LINQ to SQL) and not have the database return all ActiveRecord.Widget instances and then filter the enumerable collection. We need to pass in an expression tree, so we ask for one as the parameter for GetMany. The snag: the parameter we have needs to be magically transformed from an Expression<Func<DataContract.Widget, bool>> to an Expression<Func<ActiveRecord.Widget, bool>>. This is where I haven't managed to pull it off... Attempted Solution What we 'd like to do inside GetMany is: IEnumerable<DataContract.Widget> GetMany( Expression<Func<DataContract.Widget, bool>> predicate) { var lambda = Expression.Lambda<Func<ActiveRecord.Widget, bool>>( predicate.Body, predicate.Parameters); // use lambda to query ActiveRecord.Widget and return some value } This won't work because in a typical scenario, for example if: predicate == w => w.Id == 0; ...the expression tree contains a MemberAccessExpression instance which has a MemberInfo property (named Member) that point to members of DataContract.Widget. There are also ParameterExpression instances both in the expression tree and in its parameter expression collection (predicate.Parameters); After searching a bit, I found System.Linq.Expressions.ExpressionVisitor (its source can be found here in the context of a how-to, very helpful) which is a convenient way to modify an expression tree. Armed with this, I implemented a visitor. This simple visitor only takes care of changing the types in member access and parameter expressions. It may not be complete, but it's fine for the expression w => w.Id == 0. internal class Visitor : ExpressionVisitor { private readonly Func<Type, Type> dataContractToActiveRecordTypeConverter; public Visitor(Func<Type, Type> dataContractToActiveRecordTypeConverter) { this.dataContractToActiveRecordTypeConverter = dataContractToActiveRecordTypeConverter; } protected override Expression VisitMember(MemberExpression node) { var dataContractType = node.Member.ReflectedType; var activeRecordType = this.dataContractToActiveRecordTypeConverter(dataContractType); var converted = Expression.MakeMemberAccess( base.Visit(node.Expression), activeRecordType.GetProperty(node.Member.Name)); return converted; } protected override Expression VisitParameter(ParameterExpression node) { var dataContractType = node.Type; var activeRecordType = this.dataContractToActiveRecordTypeConverter(dataContractType); return Expression.Parameter(activeRecordType, node.Name); } } With this visitor, GetMany becomes: IEnumerable<DataContract.Widget> GetMany( Expression<Func<DataContract.Widget, bool>> predicate) { var visitor = new Visitor(...); var lambda = Expression.Lambda<Func<ActiveRecord.Widget, bool>>( visitor.Visit(predicate.Body), predicate.Parameters.Select(p => visitor.Visit(p)); var widgets = ActiveRecord.Widget.Repository().Where(lambda); // This is just for reference, see below Expression<Func<ActiveRecord.Widget, bool>> referenceLambda = w => w.Id == 0; // Here we 'd convert the widgets to instances of DataContract.Widget and // return them -- this has nothing to do with the question though. } Results The good news is that lambda is constructed just fine. The bad news is that it isn't working; it's blowing up on me when I try to use it (the exception messages are really not helpful at all). I have examined the lambda my code produces and a hardcoded lambda with the same expression; they look exactly the same. I spent hours in the debugger trying to find some difference, but I can't. When predicate is w => w.Id == 0, lambda looks exactly like referenceLambda. But the latter works with e.g. IQueryable<T>.Where, while the former does not (I have tried this in the immediate window of the debugger). I should also mention that when predicate is w => true, it all works just fine. Therefore I am assuming that I 'm not doing enough work in Visitor, but I can't find any more leads to follow on. Can someone point me in the right direction? Thanks in advance for your help!

  • Useful Java Annotations

    - by Jon
    I'm interested in finding out exactly which Java annotations people think are most useful during development. This doesn't necessarily have to limited to the core Java API, you may include annotations you found in third party libraries or annotations you've developed yourself (make sure you include a link to the source). I'm really interested in common development tasks rather than knowing why the @ManyToOne(optional=false) in JPA is awesome... Include the annotation and a description of why it's useful for general development.

  • How do I get ELMAH to work with SQL Server (permission problems)

    - by Gary McGill
    I've got ELMAH working on my (Cassini) development server, and was quite happy with it, but now that I'm trying to move everything to my production server (IIS7), the honeymoon looks like being over. I've got past the "gotcha" with IIS7, which frankly could have been better highlighted in the documentation, and if I just use the in-memory log then it works. However, I'm trying to get it to use the SQL Server log (as I do on my development system), and I'm getting an error along the lines of: The EXECUTE permission was denied on the object ELMAH_GetErrorsXml Well, fine. I know how to grant database permissions, but I'm really struggling to understand which user and which stored procs/tables I need to grant access to. The thing that's really confusing me is that I didn't have to do anything like this to get it to work on my development server. The only difference I can see is that on my development server it seems to connect as NT AUTHORITY\IUSR, whereas on my production server it seems to connect as NT AUTHORITY\NETWORK SERVICE. (It's just using a trusted connection so I've not explicitly configured it to do that - I presume it's to do with the web server). UPDATE: I've since established that because I'm using Cassini, it was actually logging in as me (an admin) and not IUSR, which explains why I didn't get any permission problems. On my development server, the IUSR account is a member of the public database role, and has access to the required database (again as "public"). There's no explicit granting of object-level permissions. [See update above - this is irrelevant]. On my production server, I've added NETWORK SERVICE in exactly the same way (public database role, explicit access to the database as "public"). Yet, I get this permission error. Why?!! [See update above - the only reason I don't get a permission error is because I'm running as an admin]. And, of course, if the fact that it works locally is just "luck", I will need to know which SPs/tables to grant access to. My guess would be all 3 SPs and not the table, but it would be good (again) to see some documentation that makes this explicit.

  • How do I get a value of a reference type in an Expression?

    - by Jon Kruger
    I have this method: public void DoSomething<T>(Expression<Func<T, object>> method) { } If this method is called like this: DoSomething(c => c.SomeMethod(new TestObject())); ... how do I get the value of the parameter that was passed into SomeMethod()? If the parameter is a value type, this works: var methodCall = (MethodCallExpression)method.Body; var parameterValue = ((ConstantExpression)methodCall.Arguments[0]).Value; However, when I pass in a reference type, methodCall.Arguments[0] is a MemberExpression, and I can't seem to figure out how to write code to get the value out of it.

  • What do I have to do and how much does it cost to get a device driver for Windows Vista / 7 (32 and

    - by Jon Cage
    I've got some drivers which are basically LibUSB-Win32 with a new .inf file do describe product/vendor ids and strings which describe my hardware. This works fine for 32 bit windows, but 64 bit versions have problems; namely that Microsoft in their wisdom require all drivers to be digitally signed. So my questions are thus: Is there a version of the LibUSB-Win32 drivers which are already signed I could use? If there aren't already some signed ones I can canibalise, what exactly do I have to do to get my drivers signed. Do I need to get 64 and 32 bit versions signed separately and will this cost more? Is this a free alternative to getting them signed? Are there any other options I should consider besides requiring that my customers boot into test mode each time they start their machines (not an option I'd consider).
