Using DPAPI / ProtectedData in a web farm environment with the User Store

- by Lachman

I was wondering if anyone had successfully used DPAPI with a user store in a web farm enviroment? Because our application is a recently converted from 1.1 to 2.0 asp.net app, we're using a custom wrapper which directly calls the CryptUnprotect methods. But this should be the same as the ProtectedData method available in the 2.0 framework. Because we are operating in a web farm environment, we can't guarantee that the machine that did the encryption is going to be the one decrypting it. (Also because machine failures shouldn't destroy our encrypted data). So what we have is a serviced component that runs in a service under a particular user account on each one of our web boxes. This user is a set up to have a roaming profile, as per the recomendation. The problem we have is that info encrypted on one machine can not be decrypted on another, this fails with the win32 error 'Key not valid for use in specified state'. I suspect that this is because I've made a mistake by having the encryption service running as the user on multiple machines, hence keeping the user logged in on more than one machine at the same time. If this is the problem, how are other using DPAPI with the User Store in a web farm environment?

"echo" in functions or "echo" all page?

- by jasmine

Is this a good method to save to all index in a variable and then echo this? for example <?php $txt='<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-9" /> <link rel="stylesheet" type="text/css" href="css/style.css"/> <title>Untitled Document</title> </head> <body> <div class="wrapper"> <div class="header"> <h2>'.heaf_func().'</h2> </div> <div class="content">content</div> <div class="footer">footer</div> </div> </body> </html>'; echo $txt; ?>

Perl XML SAX parser emulating XML::Simple record for record

- by DVK

Short Q summary: I am looking a fast XML parser (most likely a wrapper around some standard SAX parser) which will produce per-record data structure 100% identical to those produced by XML::Simple. Details: We have a large code infrastructure which depends on processing records one-by-one and expects the record to be a data structure in a format produced by XML::Simple since it always used XML::Simple since early Jurassic era. An example simple XML is: <root> <rec><f1>v1</f1><f2>v2</f2></rec> <rec><f1>v1b</f1><f2>v2b</f2></rec> <rec><f1>v1c</f1><f2>v2c</f2></rec> </root> And example rough code is: sub process_record { my ($obj, $record_hash) = @_; # do_stuff } my $records = XML::Simple->XMLin(@args)->{root}; foreach my $record (@$records) { $obj->process_record($record) }; As everyone knows XML::Simple is, well, simple. And more importantly, it is very slow and a memory hog - due to being a DOM parser and needing to build/store 100% of data in memory. So, it's not the best tool for parsing an XML file consisting of large amount of small records record-by-record. However, re-writing the entire code (which consist of large amount of "process_record"-like methods) to work with standard SAX parser seems like an big task not worth the resources, even at the cost of living with XML::Simple. What I'm looking for is an existing module which will probably be based on a SAX parser (or anything fast with small memory footprint) which can be used to produce $record hashrefs one by one based on the XML pictured above that can be passed to $obj->process_record($record) and be 100% identical to what XML::Simple's hashrefs would have been.

Access and modify attributes/objects which are not part of the form backing bean

- by spa

I use Spring MVC (via Spring Roo) to build a small web application for administering persons. In the page for creating a person the bean Person is used as form backing object (key "person" in the model map). <form:form action="${form_url}" method="POST" modelAttribute="person"> I would like to add some attributes to the model map which can be altered by the user in the creation form. Basically, I try to add a Boolean, so that I can control which page is displayed next after the user presses the submit button. I try to modify the Boolean (key "myBoolean" in the model map) using a simple checkbox: <form:checkbox id="_myboolean_id" path="myBoolean"/> However, as I am new to Spring MVC I have some difficulties here. The Boolean object is not an attribute of the form backing object. So if I try to access it the following exception is thrown (of course): Invalid property 'myBoolean' of bean class [de.cm.model.Person]: Bean property 'myBoolean' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? Is there are way to access a value of the model map directly? The only solution I can imagine right now is a kind of wrapper object around the class Person and my additional attributes which is used as a new form backing object. However, this is more work for a IMHO simple task. Do you have a better solution?

After Navigate2 Method returns S_OK Stuck at READYSTATE of READYSTATE_LOADING

- by Stone Free

I am working on a MFC Document View architecture application which has multiple documents and views and a tabbed window interface. I have been tasked with making an automatic switch to another tab on the press of the OK button in one of the other tabs. When the other tab is clicked on it uses a C++ wrapper over IWebBrowser2 to navigate to a specific web page. When this is done manually by clicking on the tab everything is fine and the webpage within the view loads successfully. In my first attempt at doing this the tab successfully switched in response to a call to AfxGetMainWnd()->SendMessageToDescendants(SOME_MESSAGE, ...); however by sending this windows message at the wrong point the application would crash once control returned because the chain of events caused the (modeless) dialog (*) that sent the message, to no longer exist. I then found the correct place to make the call, but now when the other tab is activated, it no longer displays the webpage as it should. To debug this problem I added code to check the READYSTATE in both the situation where it works and the situation where it does not. When the page fails to load (despite the call to Navigate2 returning S_OK), the READYSTATE just stays at READYSTATE_LOADING. Unfortunately now I am to many edits away from when I had it partially working. I have added TRACE statements to the most obvious events such as OnSetFocus, CView::OnActivateView but all traces come out in the same order despite the behaviour being different * hosted in the view

Python with Wiimote using pywiiuse module

- by Anon

After seeing the abilities and hackibility of wiimotes I really want to use it in my 'Intro to programming' final. Everyone must make a python program and present it to the class. I want to make a game with pygame incorporating a wiimote. I found pywiiuse which is a very basic wrapper for the wiiuse library using c types. I can NOT get anything beyond LEDs and vibrating to work. Buttons, IR, motion sensing, nothing. I've tried different versions of wiiuse, pywiiuse, even python. I can't even get the examples that came with it to run. Here's the code I made as a simple test. I copied some of the example C++ code. from pywiiuse import * from time import sleep #Init wiimotes = wiiuse_init() #Find and start the wiimote found = wiiuse_find(wiimotes,1,5) #Make the variable wiimote to the first wiimote init() found wiimote = wiimotes.contents #Set Leds wiiuse_set_leds(wiimote,WIIMOTE_LED_1) #Rumble for 1 second wiiuse_rumble(wiimote,1) sleep(1) wiiuse_rumble(wiimote,0) #Turn motion sensing on(supposedly) wiiuse_motion_sensing(wiimote,1) while 1: #Poll the wiimotes to get the status like pitch or roll if(wiiuse_poll(wiimote,1)): print 'EVENT' And here's the output when I run it. wiiuse version 0.9 wiiuse api version 8 [INFO] Found wiimote [assigned wiimote id 1]. EVENT EVENT Traceback (most recent call last): File "C:\Documents and Settings\Nick\Desktop\wiimotetext.py", line 26, in <mod ule> if(wiiuse_poll(wiimote,1)): WindowsError: exception: access violation reading 0x00000004 It seems each time I run it, it prints out EVENT 2-5 times until the trace back. I have no clue what to do at this point, I've been trying for the past two days to get it working. Thanks!

CSS absolute DIV causing other absolute DIV problems

- by Tim

Hello, I have implemented a chat script which requires an absolutely positioned DIV to be wrapped around the pages content. This is to ensure the chat windows stay at the bottom. The problem is that because of the absolute positioning of this main wrapper, all other absolutely positioned elements (eg. Jquery Auto-completes, datepicker's etc) now scroll up and down with the page. Here is an example of the HTML: <body> <div id="main_container"> <div id="content">Elements like Jquery Autocompletes, Datepickers with absolute positioned elements in here</div> </div> The DIV "main_container" style looks like this: #main_container { width:100%; background-color:#ffffff; /* DO NOT REMOVE THIS; or you'll have issue w/ the scrollbar, when the mouse pointer is on a white space */ overflow-x: hidden; overflow-y: scroll; height:100%; /* this will make sure that the height will extend at the bottom */ position:absolute; /* container div must be absolute, for our fixed bar to work */ } I hope there is a simple fix as the chat script is too good to get rid of. Thanks, Tim

Convert function to read from string instead of file in C

- by Dusty

I've been tasked with updating a function which currently reads in a configuration file from disk and populates a structure: static int LoadFromFile(FILE *Stream, ConfigStructure *cs) { int tempInt; ... if ( fscanf( Stream, "Version: %d\n",&tempInt) != 1 ) { printf("Unable to read version number\n"); return 0; } cs->Version = tempInt; ... } to one which allows us to bypass writing the configuration to disk and instead pass it directly in memory, roughly equivalent to this: static int LoadFromString(char *Stream, ConfigStructure *cs) A few things to note: The current LoadFromFile function is incredibly dense and complex, reading dozens of versions of the config file in a backward compatible manner, which makes duplication of the overall logic quite a pain. The functions that generate the config file and those that read it originate in totally different parts of the old system and therefore don't share any data structures so I can't pass those directly. I could potentially write a wrapper, but again, it would need to handle any structure passed in in a backwards compatible manner. I'm tempted to just pass the file as is in as a string (as in the prototype above) and convert all the fscanf's to sscanf's but then I have to handle incrementing the pointer along (and potentially dealing with buffer overrun errors) manually. This has to remain in C, so no C++ functionality like streams can help here Am I missing a better option? Is there some way to create a FILE * that actually just points to a location in memory instead of on disk? Any pointers, suggestions or other help is greatly appreciated.

How to compile a C DLL for 64 bit with Visual Studio 2010?

- by Daren Thomas

I have a DLL written in C in source code. This is the code for the General Polygon Clipper (in case you are interested). I'm using it in a C# project via the C# wrapper provided on the homepage. This comes with a precompiled DLL. Since switching to a 64bit Development machine with Visual Studio 2010 and Windows 7 64 bit, the application won't run anymore. This is the error I get: An attempt was made to load a program with an incorrect format. This is because of DLLImporting the 32bit gpc.dll, as I have gathered from stuff found on the web. I assume this will all go away if I recompile the DLL to 64bit, but can't for the love of me figure out how to do so. My C skills are basic, in that I can write a C program with the GNU tools, but have no experience with various compilers / processors / IDEs etc. I believe I could port this to C#. By that I mean I trust myself to actually pull it off. But I'd prefer not to, since it is a lot of work that I'd prefer a compiler to do for me ;)

Receiving DB update events in .NET from SQLite

- by Dan Tao

I've recently discovered the awesomeness of SQLite, specifically the .NET wrapper for SQLite at http://sqlite.phxsoftware.com/. Now, suppose I'm developing software that will be running on multiple machines on the same network. Nothing crazy, probably only 5 or 6 machines. And each of these instances of the software will be accessing an SQLite database stored in a file in a shared directory (is this a bad idea? If so, tell me!). Is there a way for each instance of the app to be notifiied if one instance updates the database file? One obvious way would be to use the FileSystemWatcher class, read the entire database into a DataSet, and then ... you know ... enumerate through the entire thing to see what's new ... but yeah, that seems pretty idiotic, actually. Is there such a thing as a provider of SQLite updates? Does this even make sense as a question? I'm also pretty much a newbie when it comes to ADO.NET, so I might be approaching the problem from the entirely wrong angle.

HTML include statement

- by iMaster

I'm just trying to do a simple include statement in HTML. I have no clue why its not working. My file setup is basically index.php in the root and then a file called "includes" with a file "header.html" inside. So here's my code: <!DOCTYPE html> <html lang="en"> <html> <head> <title>Title</title> <link type="text/css" href="style/style.css" media="screen" rel="stylesheet"> <script src="scripts/jquery.js" type="text/javascript"></script> <script src="scripts/code.js" type="text/javascript"></script> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> </head> <body> <div id="wrapper">  ...blah blah blah </div> </body> </html> I've verified that the file is there so I'm not sure what else the problem could be. Thanks!

Why wouldn't a flex remoteobject be able to work within a custom component?

- by Gary

Please enlighten this flex noob. I have a remoteobject within my main.mxml. I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint. When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence. How could this be? No spelling errors, or anything like that. What can I do to figure it out? mxml code: < mx:RemoteObject id="myService" destination="remoteService" endpoint="$(Application.application.home}/messagebroker/amf" > < /mx:RemoteObject > function call is just 'myService.getlist();' when I move it to a custom component, I import mx.core.Application; so the compiler doesn't yell my child component: child.mxml <mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" > <mx:Script> <![CDATA[ import mx.core.Application; public function init():void { helloWorld.sayHello(); } ]]> </mx:Script> <mx:RemoteObject id="helloWorld" destination="helloService" endpoint="$(Application.application.home}/messagebroker/amf" /> <mx:Label text="{helloWorld.sayHello.lastResult}" /> </mx:Panel> my main.mxml: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" xmlns:test="main.flex.*" > <mx:Script> <![CDATA[ [Bindable] public var home:String; [Bindable] public var uName:String; public function init():void { //passed in by wrapper html home = Application.application.parameters.appHome; uName = Application.application.parameters.uName; } ]]> </mx:Script> <test:child /> </mx:Application>

magento - multilingual site + Add store codes to url - want to show flag icons

I want to have a multi-language magento site use a flag image instead of a language selector box for user to select language of page. There is a nice article on this at http://www.atwix.com/magento/replace-language-selector-flag-icons/ Only issue is that we use "Add store codes to url" option. I hacked this code, but it can use some refinement and make it more Magento looking. <?php if(count($this->getStores())>1): ?> <div class="form-language"> <div class="langs-wrapper"> <?php foreach ($this->getStores() as $_lang): ?> <?php if ($_lang->getCode() != 'default'): ?> <? $base_url = Mage::getBaseUrl(); // remove language in base url $base_url = str_replace('/en/' , "" , $base_url); $base_url = str_replace('/fr/' , "" , $base_url); $current_url = $this->helper('core/url')->getCurrentUrl(); // take out base url and language code $rest_of_url = str_replace($base_url , "" , $current_url); $rest_of_url = str_replace('/en/' , "" , $rest_of_url); $rest_of_url = str_replace('/fr/' , "" , $rest_of_url); // assmble new url $new_url = $base_url .

vtk glyphs 3D, indenpently color and rotation

- by user3684219

I try to display thanks to vtk (python wrapper) several glyphs in a scene with each their own colour and rotation. Unfortunately, just the rotation (using vtkTensorGlyph) is taken in consideration by vtk. Reversely, just color is taken in consideration when I use a vtkGlyph3D. Here is a ready to use piece of code with a vtkTensorGlyph. Each cube should have a random color but there all will be in the same color. I read and read again the doc of vtk but I found no solution. Thanks in advance for any idea #!/usr/bin/env python # -*- coding: utf-8 -*- import vtk import scipy.linalg as sc import random as ra import numpy as np import itertools points = vtk.vtk.vtkPoints() # where to locate each glyph in the scene tensors = vtk.vtkDoubleArray() # rotation for each glyph tensors.SetNumberOfComponents(9) colors = vtk.vtkUnsignedCharArray() # should be the color for each glyph colors.SetNumberOfComponents(3) # let's make 10 cubes in the scene for i in range(0, 50, 5): points.InsertNextPoint(i, i, i) # position of a glyph colors.InsertNextTuple3(ra.randint(0, 255), ra.randint(0, 255), ra.randint(0, 255) ) # pick random color rot = list(itertools.chain(*np.reshape(sc.orth(np.random.rand(3, 3)).transpose(), (1, 9)).tolist())) # random rotation matrix (row major) tensors.InsertNextTuple9(*rot) polydata = vtk.vtkPolyData() # create the polydatas polydata.SetPoints(points) polydata.GetPointData().SetTensors(tensors) polydata.GetPointData().SetScalars(colors) cubeSource = vtk.vtkCubeSource() cubeSource.Update() glyphTensor = vtk.vtkTensorGlyph() glyphTensor.SetColorModeToScalars() # is it really work ? try: glyphTensor.SetInput(polydata) except AttributeError: glyphTensor.SetInputData(polydata) glyphTensor.SetSourceConnection(cubeSource.GetOutputPort()) glyphTensor.ColorGlyphsOn() # should not color all cubes independently ? glyphTensor.ThreeGlyphsOff() glyphTensor.ExtractEigenvaluesOff() glyphTensor.Update() # next is usual vtk code mapper = vtk.vtkPolyDataMapper() mapper.SetInputConnection(glyphTensor.GetOutputPort()) actor = vtk.vtkActor() actor.SetMapper(mapper) ren = vtk.vtkRenderer() ren.SetBackground(0.2, 0.5, 0.3) ren.AddActor(actor) renwin = vtk.vtkRenderWindow() renwin.AddRenderer(ren) iren = vtk.vtkRenderWindowInteractor() iren.SetInteractorStyle(vtk.vtkInteractorStyleTrackballCamera()) iren.SetRenderWindow(renwin) renwin.Render() iren.Initialize() renwin.Render() iren.Start()

Fast JSON serialization (and comparison with Pickle) for cluster computing in Python?

- by user248237

I have a set of data points, each described by a dictionary. The processing of each data point is independent and I submit each one as a separate job to a cluster. Each data point has a unique name, and my cluster submission wrapper simply calls a script that takes a data point's name and a file describing all the data points. That script then accesses the data point from the file and performs the computation. Since each job has to load the set of all points only to retrieve the point to be run, I wanted to optimize this step by serializing the file describing the set of points into an easily retrievable format. I tried using JSONpickle, using the following method, to serialize a dictionary describing all the data points to file: def json_serialize(obj, filename, use_jsonpickle=True): f = open(filename, 'w') if use_jsonpickle: import jsonpickle json_obj = jsonpickle.encode(obj) f.write(json_obj) else: simplejson.dump(obj, f, indent=1) f.close() The dictionary contains very simple objects (lists, strings, floats, etc.) and has a total of 54,000 keys. The json file is ~20 Megabytes in size. It takes ~20 seconds to load this file into memory, which seems very slow to me. I switched to using pickle with the same exact object, and found that it generates a file that's about 7.8 megabytes in size, and can be loaded in ~1-2 seconds. This is a significant improvement, but it still seems like loading of a small object (less than 100,000 entries) should be faster. Aside from that, pickle is not human readable, which was the big advantage of JSON for me. Is there a way to use JSON to get similar or better speed ups? If not, do you have other ideas on structuring this? (Is the right solution to simply "slice" the file describing each event into a separate file and pass that on to the script that runs a data point in a cluster job? It seems like that could lead to a proliferation of files). thanks.

Python c_types .dll functions (pari library)

- by silinter

Alright, so a couple days ago I decided to try and write a primitive wrapper for the PARI library. Ever since then I've been playing with ctypes library in loading the dll and accessing the functions contained using code similar to the following: from ctypes import * libcyg=CDLL("<path/cygwin1.dll") #It needs cygwin to be loaded. Not sure why. pari=CDLL("<path>/libpari-gmp-2.4.dll") print pari.fibo #fibonacci function #prints something like "<_FuncPtr object at 0x00BA5828>" So the functions are there and they can potentially be accessed, but I always recieve an access violation no matter what I try. For example: pari.fibo(5) #access violation pari.fibo(c_int(5)) #access violation pari.fibo.argtypes=[c_long] #setting arguments manually pari.fibo.restype=long #set the return type pari.fibo(byref(c_int(5))) #access violation reading 0x04 consistently and any variation on that, including setting argtypes to receive pointers. The Pari .dll is written in C and the fibonacci function's syntax within the library is GEN fibo(long x) (docs @http://pari.math.u-bordeaux.fr/dochtml/html/Arithmetic_functions.html#fibonacci, I need more rep it seems). Could it be the return type that's causing these errors, as it is not a standard int or long but a GEN type, which is unique to the PARI library? Any help would be appreciated. If anyone is able to successfully load the library and use ANY function from within python, please tell; I've been at this for hours now.

CFHost DNS Resolution - When is it OK to use synchronous API?

- by Jasarien

I went to the iPhone Developer Tech Talk a few months ago and asked one of the gurus there about the lack of NSHost on the iPhone. Some code I was porting to the iPhone made significant use of NSHost throughout its networking code. I was told that NSHost is on the iPhone, but its private. I was also told that NSHost is a synchronous API and that I shouldn't use it anyway. (If anyone could elaborate on why it shouldn't be used, as a bonus, that'd be great.) I can see the caveats of using synchronous API's on the main thread in that they'll block until complete - and that's never a good thing with network code because there are so many factors that could cause the API to block the thread for a significant amount of time. My solution was to write a wrapper around CFHost's asynchronous resolution functions. The result works quite well, and I'm considering releasing it into the public domain. But my question is this: Say my app only resolves a hostname once per run, during the connecting phase, and then cache's it for the rest of the session. During the time it is resolving, a modal screen is shown telling the user "Connecting" with a nice spinner. Does it really matter whether or not the resolution is asynchronous?? The user has to wait to connect anyway, and the resolution is only done on the first connection. Subsequent connections use the cached result of the resolution. When is it OK to be synchronous and when should things be asynchronous?

Good hash function for a 2d index

- by rlbond

I have a struct called Point. Point is pretty simple: struct Point { Row row; Column column; // some other code for addition and subtraction of points is there too } Row and Column are basically glorified ints, but I got sick of accidentally transposing the input arguments to functions and gave them each a wrapper class. Right now I use a set of points, but repeated lookups are really slowing things down. I want to switch to an unordered_set. So, I want to have an unordered_set of Points. Typically this set might contain, for example, every point on a 80x24 terminal = 1920 points. I need a good hash function. I just came up with the following: struct PointHash : public std::unary_function<Point, std::size_t> { result_type operator()(const argument_type& val) const { return val.row.value() * 1000 + val.col.value(); } }; However, I'm not sure that this is really a good hash function. I wanted something fast, since I need to do many lookups very quickly. Is there a better hash function I can use, or is this OK?

How do I use Linq-to-sql to iterate db records?

- by Seth Spearman

I asked on SO a few days ago what was the simplest quickest way to build a wrapper around a recently completed database. I took the advice and used sqlmetal to build linq classes around my database design. Now I am having two problems. One, I don't know LINQ. And, two, I have been shocked to realize how hard it is to learn. I have a book on LINQ (Linq In Action by Manning) and it has helped some but at the end of the day it is going to take me a couple of weeks to get traction and I need to make some progress on my project today. So, I am looking for some help getting started. Click HERE To see my simple database schema. Click HERE to see the vb class that was generated for the schema. My needs are simple. I have a console app. The main table is the SupplyModel table. Most of the other tables are child tables of the SupplyModel table. I want to iterate through each of Supply Model records. I want to grab the data for a supply model and then DoStuff with the data. And I also need to iterate through the child records, for each supply model, for example the NumberedInventories and DoStuff with that as well. I need help doing this in VB rather than C# if possible. I am not looking for the whole solution...if you can supply a couple of code-snippets to get me on my way that would be great. Thanks for your help. Seth

Disassembling with python - no easy solution?

- by Abc4599

Hi, I'm trying to create a python script that will disassemble a binary (a Windows exe to be precise) and analyze its code. I need the ability to take a certain buffer, and extract some sort of struct containing information about the instructions in it. I've worked with libdisasm in C before, and I found it's interface quite intuitive and comfortable. The problem is, its Python interface is available only through SWIG, and I can't get it to compile properly under Windows. At the availability aspect, diStorm provides a nice out-of-the-box interface, but it provides only the Mnemonic of each instruction, and not a binary struct with enumerations defining instruction type and what not. This is quite uncomfortable for my purpose, and will require a lot of what I see as spent time wrapping the interface to make it fit my needs. I've also looked at BeaEngine, which does in fact provide the output I need, a struct with binary info concerning each instruction, but its interface is really odd and counter-intuitive, and it crashes pretty much instantly when provided with wrong arguments. The CTypes sort of ultimate-death-to-your-python crashes. So, I'd be happy to hear about other solutions, which are a little less time consuming than messing around with djgcc or mingw to make SWIGed libdisasm, or writing an OOP wrapper for diStorm. If anyone has some guidance as to how to compile SWIGed libdisasm, or better yet, a compiled binary (pyd or dll+py), I'd love to hear/have it. :) Thanks ahead.

Stored insert procedure in plpgsql

- by crazyphoton

I want to do something like this in PostgreSQL. I tried this: CREATE or replace FUNCTION create_patient(_name text, _email text, _phone text, _password text, _field1 text, _field2 text, _field3 timestamp, _field4 text, OUT _pid integer, OUT _id integer) RETURNS record AS $$ DECLARE _id integer; _type text; _pid integer; BEGIN _type := 'patient'; INSERT into patients (name, email, phone, field1, field2, field3) values (_name, _email, _phone, _field1, _field2, _field3) RETURNING id into _pid; INSERT into users (username, password, type, pid, phone, language) values (_email, _password, _type, _pid, _phone, _field4) RETURNING id into _id; END; $$ LANGUAGE plpgsql; But there are a lot of instances where I would not want to specify some of field1/field2/field3/field4 and want the unspecified fields to use the default value in the table. Currently that is not possible, because to call this function I need to specify all fields. TLDR; Is there a simple way to create a wrapper procedure for INSERT in PL/pgSQL where I can specify which fields I want to insert?

Debugging mono assembly load error

- by Will I Am

I am running asp.net/mono on Ubuntu with lighthttpd/fastcgi. Somehow I suspect an assembly reference sneaked in that I cannot track down, and it's causing my application to fail (it works fine on windows under MS.NET). When I try it under mono, I get: Failed to create shadow copy (CopyFile). Description: HTTP 500. Error processing request. Stack Trace: System.ExecutionEngineException: Failed to create shadow copy (CopyFile). at (wrapper managed-to-native) System.Reflection.Assembly:LoadFrom (string,bool) at System.Reflection.Assembly.LoadFrom (System.String assemblyFile) [0x00000] at System.Web.Compilation.BuildManager.LoadAssembly (System.String path, System.Collections.Generic.List`1 al) [0x00000] at System.Web.Compilation.BuildManager.GetReferencedAssemblies () [0x00000] at System.Web.Compilation.BuildManager.GenerateAssembly (System.Web.Compilation.AssemblyBuilder abuilder, System.Collections.Generic.List`1 buildItems, System.Web.VirtualPath virtualPath, BuildKind buildKind) [0x00000] at System.Web.Compilation.BuildManager.BuildAssembly (System.Web.VirtualPath virtualPath) [0x00000] at System.Web.Compilation.BuildManager.GetCompiledType (System.String virtualPath) [0x00000] at System.Web.HttpApplicationFactory.InitType (System.Web.HttpContext context) [0x00000] Version information: Mono Version: 2.0.50727.1433; ASP.NET Version: 2.0.50727.1433 I am at a loss to how to debug this, as it's not giving me a hint of what assembly it's having problem with. Any ideas?

Jeditable setting default selected value after change.

- by Dk589

My app allows the user to update a field via a drop down box using jeditable. When the program is loaded i created this function to get the selected value and set it as the selected value in jeditable. But after i change the value, the selected tag stays set as the old value. how can i make it change to the new value? this is the function function updateType(ID,type){ $(document).ready(function(){ $('#tweekType-'+ID).editable("edit.php?type=tweekType", { data : " {'copywriting':'Copywriting','design':'Design','code':'Code', 'selected':'"+type+"'}", type : 'select' }); }); this is the wrapper around the tag. <span id="tweekType-<?php echo $getTweaksReturned->tweekID; ?>"> <?php type($getTweaksReturned->type); ?> <script>updateType('<?php echo $getTweaksReturned->tweekID; ?>','<? echo $getTweaksReturned->type; ?>'); </script> </span> The same tag is replicated on the page the returns the new variable.

Possible to Inspect Innards of Core C# Functionality

- by Nick Babcock

I was struck today, with the inclination to compare the innards of Buffer.BlockCopy and Array.CopyTo. I am curious to see if Array.CopyTo called Buffer.BlockCopy behind the scenes. There is no practical purpose behind this, I just want to further my understanding of the C# language and how it is implemented. Don't jump the gun and accuse me of micro-optimization, but you can accuse me of being curious! When I ran ILasm on mscorlib.dll I received this for Array.CopyTo .method public hidebysig newslot virtual final instance void CopyTo(class System.Array 'array', int32 index) cil managed { // Code size 0 (0x0) } // end of method Array::CopyTo and this for Buffer.BlockCopy .method public hidebysig static void BlockCopy(class System.Array src, int32 srcOffset, class System.Array dst, int32 dstOffset, int32 count) cil managed internalcall { .custom instance void System.Security.SecuritySafeCriticalAttribute::.ctor() = ( 01 00 00 00 ) } // end of method Buffer::BlockCopy Which, frankly, baffles me. I've never run ILasm on a dll/exe I didn't create. Does this mean that I won't be able to see how these functions are implemented? Searching around only revealed a stackoverflow question, which Marc Gravell said [Buffer.BlockCopy] is basically a wrapper over a raw mem-copy While insightful, it doesn't answer my question if Array.CopyTo calls Buffer.BlockCopy. I'm specifically interested in if I'm able to see how these two functions are implemented, and if I had future questions about the internals of C#, if it is possible for me to investigate it. Or am I out of luck?

I'm having a strange issue on a galaxy nexus when trying to have a live camera view in my app. I get this error in the log cat: 06-29 16:31:26.681 I/CameraClient(133): Opening camera 0 06-29 16:31:26.681 I/CameraHAL(133): camera_device open 06-29 16:31:26.970 D/DOMX (133): ERROR: failed check:(eError == OMX_ErrorNone) || (eError == OMX_ErrorNoMore) - returning error: 0x80001005 - Error returned from OMX API in ducati 06-29 16:31:26.970 E/CameraHAL(133): Error while configuring rotation 0x80001005 06-29 16:31:27.088 I/am_on_resume_called(21274): [0,digifynotes.Activity_Camera] 06-29 16:31:27.111 V/PhoneStatusBar(693): setLightsOn(true) 06-29 16:31:27.205 E/CameraHAL(133): OMX component is not in loaded state 06-29 16:31:27.205 E/CameraHAL(133): setNSF() failed -22 06-29 16:31:27.205 E/CameraHAL(133): Error: CAMERA_QUERY_RESOLUTION_PREVIEW -22 06-29 16:31:27.252 I/MonoDroid(21274): UNHANDLED EXCEPTION: Java.Lang.Exception: Exception of type 'Java.Lang.Exception' was thrown. 06-29 16:31:27.252 I/MonoDroid(21274): at Android.Runtime.JNIEnv.CallVoidMethod (intptr,intptr) <0x00068> 06-29 16:31:27.252 I/MonoDroid(21274): at Android.Hardware.Camera.StartPreview () <0x0007f> 06-29 16:31:27.252 I/MonoDroid(21274): at DigifyNotes.CameraPreviewView.SurfaceChanged (Android.Views.ISurfaceHolder,Android.Graphics.Format,int,int) <0x000d7> 06-29 16:31:27.252 I/MonoDroid(21274): at Android.Views.ISurfaceHolderCallbackInvoker.n_SurfaceChanged_Landroid_view_SurfaceHolder_III (intptr,intptr,intptr,int,int,int) <0x0008b> 06-29 16:31:27.252 I/MonoDroid(21274): at (wrapper dynamic-method) object.4c65d912-497c-4a67-9046-4b33a55403df (intptr,intptr,intptr,int,int,int) <0x0006b> That very same source code works flawlessly on a Samsung Galaxy Ace 2X (4.0.4) and an LG G2X (2.3.7).
