• Code First / Database First / Model First : are they just personnal preferences?

  - by Antoine M

  Merely knowing the internal functionality of each approaches, and after reading a lot of posts, I still can't figure out if each one of them is just a matter of personnal preference for the developper or if they deserve different axes of productivity ? Does one of them should be applyed for some specific productivity needs or MS is just beeing kind offering three different flavours ? Should we consider CF as a sort of improvement over DBF or MF and thinking of it as a futur standard on wich spending a peculiar intelectual investment ... ? Is there a link showing a sort of synthetic table with un-passionate pros and cons for each approach, a little bit like for web-forms and MVC. Sorry for those who will find this question redondant. I know it is.

• Android and Kernel-Modules...

  - by Nils Pipenbrinck

  So - Android is build on top of a stripped down linux system. Most of the convenient utilities are missing but all the basics are there. I can call insmod and rmmod. No problem. But where do kernel-modules and firmware files reside? I can't find any. there is no /lib/modules in the standard distribution. Problem: I need modules. For sure don't want to compile support for each and every usb-device in the world into the linux-kernel. Where should I put them?

• Is it dangerous to store user-enterable text into a hidden form via javascript?

  - by KallDrexx

  In my asp.net MVC application I am using in place editors to allow users to edit fields without having a standard form view. Unfortunately, since I am using Linq to Sql combined with my data mapping layer I cannot just update one field at a time and instead need to send all fields over at once. So the solution I came up with was to store all my model fields into hidden fields, and provide span tags that contain the visible data (these span tags become editable due to my jquery plugin). When a user triggers a save of their edits of a field, jquery then takes their value and places it in the hidden form, and sends the whole form to the server to commit via ajax. When the data goes into the hidden field originally (page load) and into the span tags the data is properly encoded, but upon the user changing the data in the contenteditable span field, I just run $("#hiddenfield").val($("#spanfield").html(); Am I opening any holes this method? Obviously the server also properly encodes stuff prior to database entry.

• Launch external application from C++ program and attach it to visual 2008 debugger while debugging host in WinAPI

  - by PiotrK

  Basically I have Host and Child program. I do not have sources for Child so I can't change anything in it. I want to launch Host from debugger, which at some point should launch Child program. I want to attach Child automatically for debugging session as well (so any breakpoints set in DLL sources loaded under Child process will hit). How to do this in Visual Studio 2008 C++ with standard WinAPI? I tried this: SHELLEXECUTEINFO sei = {0}; sei.cbSize = sizeof (SHELLEXECUTEINFO); sei.fMask = SEE_MASK_NOCLOSEPROCESS; sei.lpVerb = "open"; sei.lpFile = "Child.exe"; sei.lpParameters = "/Param"; sei.nShow = SW_SHOWNORMAL; if (ShellExecuteEx (&sei)) { WaitForSingleObject (sei.hProcess, INFINITE); } But this does not attach debugger for Child.exe

• SForceAPI : unable to find classes listed on API? (Account, Contact, etc)

  - by Firefox

  Hi, API referred : http://www.salesforce.com/us/developer/docs/api/index.htm subsection: reference-standard objects Client side details : partner.wsdl, Axis2 1.5, generated stubs using unpacked option (-u). I was hoping to find some basic objects like Account, Contact, etc (which were listed on above url) so that I can do something like - SObject[] sObjArray = queryResult.getRecords(); for(SObject sObj : sObjArray){ Account acc = [Account] sObj; } [used above approach successfully in another webservice - 'Zuora'] However, I could not find Account class in the generated classes. I guess I am into wrong approach, but atleast I should be finding the classes listed in the reference API. Please help.

• Supervisor callback for child normal exit

  - by Aler

  I am creating a test app where is one supervisor with simple_one_for_one strategy and many worker children added dynamically to it. How to implement callback (or receive a message) in supervisor that will be called when child exit normally? Main goal is to notify some other process that all supervised worker processes are done and it's time to show final report. How to design such kind of behavior? Should I create my own behavior that combine supervisor and gen_server, or there is a way to do this with standard otp behaviors?

• Service Application too visible

  - by Tom

  Working on a service application in Delphi 5 that is intended to run on Windows XP - 7. Most of the application is coming together nicely, but I'm running into one issue. Part of this service application is a form that displays data occasionally (similar to the slider box Avast uses to let you know its updated). When the service shows the form, the form displays on the taskbar, but we don't want it to. Does anyone have any suggestions as to how to hide the form's button on the taksbar? None of the standard methods I've found for regular applications have worked so far. Thanks.

• Declaring pointers; asterisk on the left or right of the space between the type and name?

  - by GenTiradentes

  I've seen mixed versions of this in a lot of code. (This applies to C and C++, by the way.) People seem to declare pointers in one of two ways, and I have no idea which one is correct, of if it even matters. The first way it to put the asterisk adjacent the type name, like so: someType* somePtr; The second way is to put the asterisk adjacent the name of the variable, like so: someType *somePtr; This has been driving me nuts for some time now. Is there any standard way of declaring pointers? Does it even matter how pointers are declared? I've used both declarations before, and I know that the compiler doesn't care which way it is. However, the fact that I've seen pointers declared in two different ways leads me to believe that there's a reason behind it. I'm curious if either method is more readable or logical in some way that I'm missing.

• Incremement Page Hit Count in Django

  - by Andrew C

  I have a table with an IntegerField (hit_count), and when a page is visited (ie. http://site/page/3) I want record id 3 'hit_count' column in the database to increment by 1. The query should be like: update table set hit_count = hit_count + 1 where id=3 Can I do this with the standard Django Model conventions? Or should I just write the query by hand? I'm starting a new project, so I am trying to avoid hacks. We'll see how long this lasts! Thanks!

• PreferenceActivity used as main activity has strange animation

  - by Tobia Loschiavo

  Hi, I have a preference screen (subclass of PreferenceActivity) set as main activity (opened when the application starts). Anyway the animation android uses to open this activity is different from standard activity. It seems that two types of animation run concurrently: the usual fade animation and the right to left one. This is the code of the onCreate() method: getPreferenceManager().setSharedPreferencesName("app"); addPreferencesFromResource(R.xml.preferences); screen = getPreferenceScreen(); How can fix this glitch? Thanks

• Only compiles as an array of pointers, not array of arrays

  - by Dustin

  Suppose I define two arrays, each of which have 2 elements (for theoretical purposes): char const *arr1[] = { "i", "j" }; char const *arr2[] = { "m", "n" }; Is there a way to define a multidimensional array that contains these two arrays as elements? I was thinking of something like the following, but my compiler displays warnings about incompatible types: char const *combine[][2] = { arr1, arr2 }; The only way it would compile was to make the compiler treat the arrays as pointers: char const *const *combine[] = { arr1, arr2 }; Is that really the only way to do it or can I preserve the type somehow (in C++, the runtime type information would know it is an array) and treat combine as a multidimensional array? I realise it works because an array name is a const pointer, but I'm just wondering if there is a way to do what I'm asking in standard C/C++ rather than relying on compiler extensions. Perhaps I've gotten a bit too used to Python's lists where I could just throw anything in them...

• Setting up a Git remote with a truncated history

  - by drg

  I am in the midst of doing some non-standard, probably doomed, experiments on a git repository. The goal is to create a remote repository with a truncated history which can still share commits with an internal repository which has a full history. I've had some success using a graft to connect the public history with the private history - when I push from my internal repository, only the post-graft contents are included. So my main question is: what is the simplest way of taking a commit, eliminating its parent and writing a graft in place of the parent? A more general question: is what I'm trying to do going to cause me pain in the long run, do you know if there's a better way?

• First Fluent NHibernate Project

  - by Andy

  I'm trying to follow the "Your first project" tutorial at http://wiki.fluentnhibernate.org/Getting_started and have hit a roadblock. When I try to run the console application, I'm getting this error: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. I have created a SQLite database "firstProject.db" and referenced the full path to the file in the call to: return Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile)) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>()) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); so I don't know what I'm doing wrong. What/where is this "PotentialReasons" collection? Thank you for the help. Andy

• Are there any open source SimpleTest Test Cases that test PHP SPL interfaces

  - by JW

  I have quite a few objects in my system that implement the PHP SPL Iterator interface. As I write them I also write tests. I know that writing tests is generally NOT a cut 'n paste job. But, when it comes to testing classes that implement Standard PHP Library interfaces, surely it makes sense to have a few script snippets that can be borrowed and dropped in to a Test class - purely to test that particular interface. It seems sensible to have these publicly available. So, I was wondering if you knew of any?

• "Dynamic" java validation framework?

  - by pihentagy

  AFAIK JSR-303 is the standard bean validation system. I don't know whether it could do validations like this (I guess no): if an object has a deleted flag set, you cannot modify the object you cannot change the start date property, after the date is passed you cannot decrease some integer properties in the bean So how can I handle validations, which depend on the previous state of an object? I would like to solve problems like that in hibernate3.5 - spring3 - JPA2 environment. Thanks My solution was to mess with hibernate, reload the object to see the old state (after evicting the new object). This time I need some smarter solution...

• Hash Digest / Array Comparison in C#

  - by Erik Karulf

  Hi All, I'm writing an application that needs to verify HMAC-SHA256 checksums. The code I currently have looks something like this: static bool VerifyIntegrity(string secret, string checksum, string data) { // Verify HMAC-SHA256 Checksum byte[] key = System.Text.Encoding.UTF8.GetBytes(secret); byte[] value = System.Text.Encoding.UTF8.GetBytes(data); byte[] checksum_bytes = System.Text.Encoding.UTF8.GetBytes(checksum); using (var hmac = new HMACSHA256(key)) { byte[] expected_bytes = hmac.ComputeHash(value); return checksum_bytes.SequenceEqual(expected_bytes); } } I know that this is susceptible to timing attacks. Is there a message digest comparison function in the standard library? I realize I could write my own time hardened comparison method, but I have to believe that this is already implemented elsewhere.

• Log out of an SSH session into Erlang VM without stopping the VM or leaving stale processes

  - by Garret Smith

  I have an Erlang application running as a daemon, configured as an SSH server. I can connect to it with an SSH client and I get the standard Erlang REPL. If I 'q().' I shut down the Erlang VM, not the connection. If I close the connection ('~.' for OpenSSH, close the window in PuTTY) some processes remain under the sshd_sup/ssh_system_xx_sup tree. These appear to be stale shell processes. I do not see any exported function in the shell module that would let me shut down the shell (and therefore the SSH connection) without affecting the entire VM. How should I be logging out of the SSH session to not leave stale processes in the VM?

• Visual C++ 2010 solution-wide macros with parameters

  - by OregonGhost

  I'm trying to compile some source code with Visual C++ 2010 Express. The code was written for GCC, and contains attributes like this: struct something { ... } __attribute__((packed)); Since this is not standard C++ syntax, Visual C++ doesn't recognize it. With this macro prior to the struct declaration, it works fine: #define __attribute__(p) But I don't want to alter the files. I created a new property sheet (GccCompat), and went to Preprocessor Definitions, and added the macro, like this: __attribute__(p) or like this: __attribute__(p)= But it doesn't work. It's simply not called. If I define just __attribute__ (without parameters) in the same location, the macro is correctly defined. Note that the command line that is generated looks fine (the macros with parameters are passed exactly the same as the ones without), but the compiler seems to ignore it. So, how can I globally define my macro with a parameter?

• algorithm for checking addresses for matches?

  - by user151841

  I'm working on a survey program where people will be given promotional considerations the first time they fill out a survey. In a lot of scenarios, the only way we can stop people from cheating the system and getting a promotion they don't deserve is to check street address strings against each other. I was looking at using levenshtein distance to give me a number to measure similarity, and consider those below a certain threshold a duplicate. However, if someone were looking to game the system, they could easily write "S 5th St" instead of "South Fifth Street", and levenshtein would consider those strings to be very different. So then I was thinking to convert all strings to a 'standard address form' i.e. 'South' becomes 's', 'Fifth' becomes '5th', etc. Then I was thinking this is hopeless, and too much effort to get it working robustly. Is it? I'm working with PHP/MySql, so I have the limitations inherent in that system.

• Compatibility of x-www-browser

  - by rohit.arondekar

  I want to open html files from a shell script. I know that Ubuntu has a command x-www-browser that will open the default browser on the system. I also found via some Googling that the command is part of the debian system. I was wondering if the command is available on non debian based distros. If it isn't is there a standard way of opening an html file in the default browser on a linux OS via command line? Note that I'm using Bash.

• extracting a quadrilateral image to a rectangle

  - by Will

  In the image below, the sign on the side of the van is not face-on to the camera. I want to calculate, as best I can with the pixels I have, what it'd look like face on. I imagine that this is some kind of loop through the x and y axis doing a Bresenham's line on both dimensions at once with some kind of mixing when pixels in the source image overlap - some sub-pixel mixing of some sort? What approaches are there, and how do you mix the pixels? Is there a standard approach for this?

• c99 goto past initialization

  - by R Samuel Klatchko

  While debugging a crash, I came across this issue in some code: int func() { char *p1 = malloc(...); if (p1 == NULL) goto err_exit; char *p2 = malloc(...); if (p2 == NULL) goto err_exit; ... err_exit: free(p2); free(p1); return -1; } The problem occurs when the first malloc fails. Because we jump across the initialization of p2, it contains random data and the call to free(p2) can crash. I would expect/hope that this would be treated the same way as in C++ where the compiler does not allow a goto to jump across an initialization. My question: is jumping across an initialization allowed by the standard or is this a bug in gcc's implementation of c99?
