• Demoted domain controller and now IIS has permissions issues

  - by tladuke

  I have a machine that was a domain controller and everything else, includin an IIS site. I built new 2 new domain controllers and transferred the FSMO roles and waited a day and then demoted the original domain controller. Now the IIS site says : HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers. I have a call in with the web app vendor, but maybe someone can guess what I need to fix now. I haven't looked at IIS since this was installed and am pretty lost. I thought about restoring the machine from a backup, but I think that would be an Active Directory disaster, right? The server is Windows 2008 (not R2). The new DCs are 2008 R2

• My Windows 8 App in Windows Store

  - by Stephen.Walther

  Finally, you have a good reason to upgrade to Windows 8! My Brain Eaters app was just accepted into the Windows Store. Just in time for Halloween! The Brain Eaters app is a sample app from my soon to be released book Windows 8 Apps with HTML5 and JavaScript. The game illustrates several important programming concepts which you need when building Windows 8 games with JavaScript such as using HTML5 Canvas and the new requestAnimationFrame() method. If you are looking for Halo or Call of Duty then you will be disappointed. If you are looking for PAC-MAN then you will be disappointed. I created the simplest arcade game that I could imagine so I could explain it in the book. All of the code for the game is included with the book. The goal of the game is to eat the food pellets while avoiding the zombies while running around a maze. Every time you get eaten by a zombie, you can hear my six year old son saying “Oh No!”. Here’s the link to the game: http://apps.microsoft.com/webpdp/app/brain-eaters/e283c8d0-1fed-4b26-a8bf-464584c9de6d

• KB980408: Fix for Explorer freezing: does anyone know what app caused it?

  - by Ian Boyd

  Microsoft released an update for Windows 7 today (Tuesday, April 27, 2010): KB980408: The April 2010 stability and reliability update for Windows 7 and Windows Server 2008 R2 is available. The update fixes, among other things: Windows Explorer may stop responding for 30 seconds when a file or a directory is created or renamed after certain applications are installed. i'm not experiencing it on my own Windows 7 machine, but two colleagues at work were experiencing the problem. i would really like to know what applications were causing problems. Microsoft will never call out the misbehaving applications. i want to know what software i should be ridiculing and insulting. And avoid in the future. Did anyone who was experiencing this problem isolate the applications?

• Importing tab delimited file into array in Visual Basic 2013 [migrated]

  - by JaceG

  I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub

• Why isn't there a typeclass for functions?

  - by Steve314

  I already tried this on Reddit, but there's no sign of a response - maybe it's the wrong place, maybe I'm too impatient. Anyway... In a learning problem I've been messing around with, I realised I needed a typeclass for functions with operations for applying, composing etc. Reasons... It can be convenient to treat a representation of a function as if it were the function itself, so that applying the function implicitly uses an interpreter, and composing functions derives a new description. Once you have a typeclass for functions, you can have derived typeclasses for special kinds of functions - in my case, I want invertible functions. For example, functions that apply integer offsets could be represented by an ADT containing an integer. Applying those functions just means adding the integer. Composition is implemented by adding the wrapped integers. The inverse function has the integer negated. The identity function wraps zero. The constant function cannot be provided because there's no suitable representation for it. Of course it doesn't need to spell things as if it the values were genuine Haskell functions, but once I had the idea, I thought a library like that must already exist and maybe even using the standard spellings. But I can't find such a typeclass in the Haskell library. I found the Data.Function module, but there's no typeclass - just some common functions that are also available from the Prelude. So - why isn't there a typeclass for functions? Is it "just because there isn't" or "because it's not so useful as you think"? Or maybe there's a fundamental problem with the idea? The biggest possible problem I've thought of so far is that function application on actual functions would probably have to be special-cased by the compiler to avoid a looping problem - in order to apply this function I need to apply the function application function, and to do that I need to call the function application function, and to do that...

• What functionality should a (basic) mock framework have?

  - by user1175327

  If i would start on writing a simple Mock framework, then what are the things that a basic mock framework MUST have? Obviously mocking any object, but what about assertions and perhaps other things? When I think of how I would write my own mock framework then I realise how much I really know (or don't know) and what I would trip up on. So this is more for educational purposes. Of course I did research and this is what i've come up with that a minimal mocking framework should be able to do. Now my question in this whole thing is, am I missing some important details in my ideas? Mocking Mocking a class: Should be able to mock any class. The Mock should preserve the properties and their original values as they were set in the original class. All method implementations are empty. Calls to methods of Mock: The Mock framework must be able to define what a mocked method must return. IE: $MockObj->CallTo('SomeMethod')->Returns('some value'); Assertions To my understanding mocking frameworks also have a set of assertions. These are the ones I think are most important (taken from SimpleTest). expect($method, $args) Arguments must match if called expectAt($timing, $method, $args) Arguments must match when called on the $timing'th time expectCallCount($method, $count) The method must be called exactly this many times expectMaximumCallCount($method, $count) Call this method no more than $count times expectMinimumCallCount($method, $count) Must be called at least $count times expectNever($method) Must never be called expectOnce($method, $args) Must be called once and with the expected arguments if supplied expectAtLeastOnce($method, $args) Must be called at least once, and always with any expected arguments And that's basically, as far as I understand, what a mock framework should be able to do. But is this really everything? Because it currently doesn't seem like a big deal to build something like this. But that's also the reason why I have the feeling that i'm missing some important details about such a framework. So is my understanding right about a mock framework? Or am i missing alot of details?

• How can I use domain masking without having self referral in Google Analytics

  - by Cdore

  I have one old domain that points to a website's server's ip (let's call it www.oldsite.com). I have a new one, www.newsite.com, that is set up to be forwarded to a specific page on the website. Due to the way the host of newsite.com places the website in a frame, in Google Analystics, the newsite.com is listed as a source rather than the source they were at before hand, causing a self referral. A solution is to edit the code of the iframe as I looked up, but there's no way to really edit the host's masking source code of course. Another solution I did previously was have www.newsite.com point to the address that www.oldsite.come pointed to. It solved the analytics problems, but in exchange, the url masking no longer worked. In the address bar, it came up as www.oldsite.com. Is there a way to make me have url masking and be able to forward to agree with google analytics? The server of the website is hosted on a cloud server, if this is anymore information.

• I don't understand the definition of side effects

  - by Chris Okyen

  I don't understand the wikipedia article on Side Effects: In computer science, a function or expression is said to have a side effect if, in addition to returning a value, it also 1.) Modifies some state or 2.) Has an observable interaction with calling functions or the outside world. I know an example of the first thing that causes a function or expression to have side effects - modifying a state Function and Expression modifying a state : 1.) foo(int X) { return x = x % x; } a = a + 1; What does 2.) - Has an observable interaction with calling functions or the outside world," mean? - Please give an example. The article continues on to say, "For example, a function might modify a global or static variable, modify one of its arguments, raise an exception, write data to a display or file, read data, or call other side-effecting functions...." Are all these examples, examples of 1.) - Modifiying some state , or are they also part of 2.) - Has an observable interaction with calling functions or the outside world?

• Go/Obj-C style interfaces with ability to extend compiled objects after initial release

  - by Skrylar

  I have a conceptual model for an object system which involves combining Go/Obj-C interfaces/protocols with being able to add virtual methods from any unit, not just the one which defines a class. The idea of this is to allow Ruby-ish open classes so you can take a minimalist approach to library development, and attach on small pieces of functionality as is actually needed by the whole program. Implementation of this involves a table of methods marked virtual in an RTTI table, which system functions are allowed to add to during module initialization. Upon typecasting an object to an interface, a Go-style lookup is done to create a vtable for that particular mapping and pass it off so you can have comparable performance to C/C++. In this case, methods may be added /afterwards/ which were not previously known and these new methods allow newer interfaces to be satisfied; while I like this idea because it seems like it would be very flexible (disregarding the potential for spaghetti code, which can happen with just about any model you use regardless). By wrapping the system calls for binding methods up in a set of clean C-compatible calls, one would also be able to integrate code with shared libraries and retain a decent amount of performance (Go does not do shared linking, and Objective-C does a dynamic lookup on each call.) Is there a valid use-case for this model that would make it worth the extra background plumbing? As much as this Dylan-style extensibility would be nice to have access to, I can't quite bring myself to a use case that would justify the overhead other than "it could make some kinds of code more extensible in future scenarios."

• How to write PowerShell code part 3 (calling external script)

  - by ybbest

  In this post, I’d like to show you how to calling external script from a PowerShell script. I’d like to use the site creation script as an example. You can download script here. 1. To call the external script, you need to first to grab the script path. You can do so by calling $scriptPath = Split-Path $myInvocation.MyCommand.Path to grab the current script path. You can then use this to build the path for your external script path. $scriptPath = Split-Path $myInvocation.MyCommand.Path $ExternalScript=$scriptPath+"\CreateSiteCollection.ps1" $configurationXmlPath=$scriptPath+"\SiteCollection.xml" [xml] $configurationXml=Get-Content $configurationXmlPath & "$ExternalScript" $configurationXml Write-Host 2.If you like to pass in any parameters , you need to define your script parameters in param () at the top of the script and separate each parameter by a comma (,) and when calling the method you do not need comma (,) to separate each parameter. #Pass in the Parameters. param ([xml] $xmlinput)

• Using a permutation table for simplex noise without storing it

  - by J. C. Leitão

  Generating Simplex noise requires a permutation table for randomisation (e.g. see this question or this example). In some applications, we need to persist the state of the permutation table. This can be done by creating the table, e.g. using def permutation_table(seed): table_size = 2**10 # arbitrary for this question l = range(1, table_size + 1) random.seed(seed) # ensures the same shuffle for a given seed random.shuffle(l) return l + l # see shared link why l + l; is a detail and storing it. Can we avoid storing the full table by generating the required elements every time they are required? Specifically, currently I store the table and call it using table[i] (table is a list). Can I avoid storing it by having a function that computes the element i, e.g. get_table_element(seed, i). I'm aware that cryptography already solved this problem using block cyphers, however, I found it too complex to go deep and implement a block cypher. Does anyone knows a simple implementation of a block cypher to this problem?

This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

• Switching PHP to FastCGI from mod_php broke AMFPHP

  - by wezzy

  Hi, i've just switched my debian server from mod_php to fastcgi following this tutorial everything goes right but now i've found that one of the hosted application that using AMFPHP for flash remoting is broken. I'm trying to understand what's happend. Looking at it with FireBug and FireAMF it seems that the responses has a content but the Flash callbacks never get called and if i try to open the service browser it displays this error: (mx.rpc::Fault)#0 errorID = 0 faultCode = "Client.Error.RequestTimeout" faultDetail = "The request timeout for the sent message was reached without receiving a response from the server." faultString = "Request timed out" message = "faultCode:Client.Error.RequestTimeout faultString:'Request timed out' faultDetail:'The request timeout for the sent message was reached without receiving a response from the server.'" name = "Error" rootCause = (null) It's strange it seems that the server takes a long time to responde, then (in the service browser) flash made a new call to the server and the old one get a response. Some problem with sessions ? Really no idea ....

• What's the proper term for a function inverse to a constructor? Deconstructor, destructor, or something else?

  - by Petr Pudlák

  Edit: I'm rephrasing the question a bit. Apparently I caused some confusion because I didn't realize that the term destructor is used in OOP for something quite different - it's a function invoked when an object is being destroyed. In functional programming we (try to) avoid mutable state so there is no such equivalent to it. (I added the proper tag to the question.) Instead, I've seen that the record field for unwrapping a value (especially for single-valued data types such as newtypes) is sometimes called destructor or perhaps deconstructor. For example, let's have (in Haskell): newtype Wrap = Wrap { unwrap :: Int } Here Wrap is the constructor and unwrap is what? I've seen both, for example: ... Most often, one supplies smart constructors and destructors for these to ease working with them. ... at Haskell wiki, or ... The general theme here is to fuse constructor - deconstructor pairs like ... at Haskell wikibook (here it's probably meant in a bit more general sense). The questions are: How do we call unwrap in functional programming? Deconstructor? Destructor? Or by some other term? And to clarify, is this terminology applicable to other functional languages, or is it used just in the Has

• Frustrated with MythTV 0.26

  - by Mike

  I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?

• C++ and system exceptions

  - by Abyx

  Why standard C++ doesn't respect system (foreign or hardware) exceptions? E.g. when null pointer dereference occurs, stack isn't unwound, destructors aren't called, and RAII doesn't work. The common advice is "to use system API". But on certain systems, specifically Win32, this doesn't work. To enable stack unwinding for this C++ code // class Foo; // void bar(const Foo&); bar(Foo(1, 2)); one should generate something like this C code Foo tempFoo; Foo_ctor(&tempFoo); __try { bar(&tempFoo); } __finally { Foo_dtor(&tempFoo); } Foo_dtor(&tempFoo); and it's impossible to implement this as C++ library. Upd: Standard doesn't forbid handling system exceptions. But it seems that popular compilers like g++ doesn't respect system exceptions on any platforms just because standard doesn't require this. The only thing that I want - is to use RAII to make code readable and program reliable. I don't want to put hand-crafted try\finally around every call to unknown code. For example in this reusable code, AbstractA::foo is such unknown code: void func(AbstractA* a, AbstractB* b) { TempFile file; a->foo(b, file); } Maybe one will pass to func such implementation of AbstractA, which every Friday will not check if b is NULL, so access violation will happen, application will terminate and temporary file will not be deleted. How many months uses will suffer because of this issue, until either author of func or author of AbstractA will do something with it? Related: Is `catch(...) { throw; }` a bad practice?

• Simplest way to render image over top of another with another image used as mask in OpenGL?

  - by Adam Naylor

  The effect I'm looking for is to have a single large background image that is always visible (at full alpha) and then show a second image (what I call a light map or specular map) that is partially shown over the top based on a third image (which is effectively a mask). The effect is similar to this effect except instead of simply darkening or lightening the background image using the third image it needs to mask the second without effecting the first at all. The third image is the only one that moves therefore hard baking the third images alpha into the second image isn't an option. If my explanation isn't clear I'll provide visual examples when I have more time. I'd prefer not to go down a shader route as I haven't taught myself this area yet so unless I have too I'd rather try to achieve this with simple alpha blending. Happy to use a shader approach. Cheers. Additional These third images are obviously light sources being cast onto the first image showing the specular information from the second image to simulate the light 'shining' off the objects in the first image. The solution I implement will need to allow two light sources to potentially overlap so my current thoughts are that the alpha values of the two images will need to be combined (Added?) to produce a final image which masks the second image? Don't worry about things like coloured lights. For this technique the lights are all considered white.

• How to write PowerShell code part 2 (Using function)

  - by ybbest

  In the last post, I have showed you how to use external configuration file in your PowerShell script. In this post, I will show you how to create PowerShell function and call external PowerShell script.You can download the script here. 1. In the original script, I create the site directly using New-SPSite command. I will refactor it so that I will create a new function to create the site using New-SPSite. The PowerShell function is quite similar to a C# method. You put your function parameters in () and separate each parameter by a comma (,). Then you put your method body in {}. function add ([int] $num1 , [int] $num2){ $total=$num1+$num2 #Return $total $total } 2. The difference is you do not need semi-colon (;) at the end of each statement and when calling the method you do not need comma (,) to separate each parameter. function add ([int] $num1 , [int] $num2){ $total=$num1+$num2 #Return $total $total } #Calling the function [int] $num1=3 [int] $num2=4 $d= add $num1 $num2 Write-Host $d 3. If you like to return anything from the function, you just need to type in the object you like to return, not need to type return .e.g. $ObjectToReturn not return $ObjectToReturn

• Oracle ADF and Simplified UI Apps: I18n Feng Shui on Display

  - by ultan o'broin

  I demoed the Hebrew language version of Oracle Sales Cloud Release 8 live in Israel recently. The crowd was yet again wowed by the simplified UI (SUI). I’ve now spent some time playing around with most of the 23 language versions, or the NLS (Natural Language Support) versions as we’d call them, available in Release 8. Hebrew Oracle Sales Cloud Release 8 The simplified UI is built using 100% Oracle ADF. This framework is a great solution for developers to productively build tablet-first, mobility-driven apps for users who work and live using natural languages other than English. Oracle ADF’s internationalization (i18n) relies on built-in Java and Unicode,  packing in i18n goodness such as Bi-Di (or bi-directional) flipping of pages, locale-enabled resource bundles, date and time support, and so on. Comparing German (left) and Hebrew Bi-Di (right) page components in the simplified UI. Note the change in the direction of the arrows and positions of the text. So, developers who need to build global apps don’t have to do anything special when using Oracle ADF components, all thanks to the baked-in UX Feng Shui, as Grant Ronald of the ADF team would say to the UK Oracle User Group. Find out more  about  ADF i18n from Frédéric Desbiens (@blueberrycoder)  on the ADF Architecture TV channel.

• Modifying the initrd.img to run additional binaries in a PXE booted RHEL 6

  I am trying to add additional automation to our existing RHEL 6 (or Oralce's implementation thereof) PXE install process by running a script in the %pre section of my kickstart config that call hpacucli, HP's raid device configuration binary.

I've unpacked the initrd.img and copied in the required libraries, binaries, and scripts but when the system boots using the modified initrd.img, the modified /lib (and /lib_64) are moved aside to /lib_old and /lib is linked to the /mnt/runtime/lib. How can I change this configuration so that the /lib is not moved (unlikely) or required libraries are available in the runtime /mnt/runtime/lib? To test and confirm this I've been able to get the install process to move to the 6th virtual console, which allows me to see errors, and then open a shell (a useful debugging mechanism). %pre exec /dev/tty6 2 /dev/tty6 chvt 6 /bin/sh

• SEO for maps-based websites that require user interaction

  - by j0nes

  I have a website that basically shows a lot of locations worldwide on a Google Maps like interface. The map itself is built using the Leaflet library and Open Street Map tiles. In the map, I show markers at each location I have. There is a popup window when I click on a marker that shows additional information and contains links to "detail" pages for this location. I fetch the location data for the viewpoint from an AJAX call from my server, so the additional information is not available in the HTML page itself. The detail pages are the pages my users are interested in. My normal users load the map, search the location they are interested in, click on a marker and click on a link in the popup window. However for search engines, this might look different. As this navigation pattern relies on user interaction, I think they might not be able to find the details page. My questions: Are search engines able to follow a navigation path like outlined above? How can I improve the navigation for search engines? (For example showing textual links below the map, sitemaps...) How important are internal links for SEO?

• Determine All SQL Server Table Sizes

  Im doing some work to migrate and optimize a large-ish (40GB) SQL Server database at the moment.  Moving such a database between data centers over the Internet is not without its challenges.  In my case, virtually all of the size of the database is the result of one table, which has over 200M rows of data.  To determine the size of this table on disk, you can run the sp_TableSize stored procedure, like so: EXEC sp_spaceused lq_ActivityLog This results in the following: Of course this is only showing one table if you have a lot of tables and need to know which ones are taking up the most space, it would be nice if you could run a query to list all of the tables, perhaps ordered by the space theyre taking up.  Thanks to Mitchel Sellers (and Gregg Starks CURSOR template) and a tiny bit of my own edits, now you can!  Create the stored procedure below and call it to see a listing of all user tables in your database, ordered by their reserved space. -- Lists Space Used for all user tablesCREATE PROCEDURE GetAllTableSizesASDECLARE @TableName VARCHAR(100)DECLARE tableCursor CURSOR FORWARD_ONLYFOR select [name]from dbo.sysobjects where OBJECTPROPERTY(id, N'IsUserTable') = 1FOR READ ONLYCREATE TABLE #TempTable( tableName varchar(100), numberofRows varchar(100), reservedSize varchar(50), dataSize varchar(50), indexSize varchar(50), unusedSize varchar(50))OPEN tableCursorWHILE (1=1)BEGIN FETCH NEXT FROM tableCursor INTO @TableName IF(@@FETCH_STATUS<>0) BREAK; INSERT #TempTable EXEC sp_spaceused @TableNameENDCLOSE tableCursorDEALLOCATE tableCursorUPDATE #TempTableSET reservedSize = REPLACE(reservedSize, ' KB', '')SELECT tableName 'Table Name',numberofRows 'Total Rows',reservedSize 'Reserved KB',dataSize 'Data Size',indexSize 'Index Size',unusedSize 'Unused Size'FROM #TempTableORDER BY CONVERT(bigint,reservedSize) DESCDROP TABLE #TempTableGO Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
