• Revamping an old and unstable IT-solution for a customer?

  - by cmbrnt

  I've been given the cumbersome task to totally redo the IT-infrastructure for a customer's office. They are currently running Windows XP all over, with one computer acting as a file server with no control over which users have access to which files, and so on. To top it off, this file server also functions as a workstation, which means it gets rebooted every time the user notices some sluggish behavior or experiences problems with flash games. To say the least, this isn't working for them. Now - I've got a very slim budget, but I need to set up a new server, and I wish to run Windows Server 2008 on it. I also need the ability to access the network remotely via VPN. Would it be a good idea to install VMware ESXi 4.1 onto the new server, and then run Windows Server 2008 as well as a separate Debian install for openvpn on it? I don't like the Domain Controller for the future AD to also run a VPN-server, because of stability issues when something goes to hell with either of them. There will be no redundancy though. However, I'm not sure if there is something to gain by installing a VPN solution on the Windows Server itself, when it comes to accessing file shares on the network via VPN. I don't know how to enable users logging in via the VPN to access the remote files, since they will be accessing the network from their own home computers (which is indeed a really bad idea, but this is what I've got to work with). They won't be logged in to the windows Domain, but rather their home workgroups. I need to be able to grant access to files in certain directories based on the logged in AD-user, but every computer won't necessarily be configured to log into the domain. I'm not sure how to explain this in a good way, but I'd be happy to clarify if somethings not clear. Any help would be great, because I've got a feeling that I can't do this without introducing a bunch of costly new rules when it comes to their IT-solution. I'd rather leave that untouched and go on my merry way to the next assignment.

• How can I extract data from Toshiba Satellite with a dead Windows installation?

  - by msanford

  I've got a Toshiba Satellite (unknown model number but bought early 2010) running Windows Vista which throws a kernel error on boot. We don't have the restore/recovery CD any more to restore the Windows partition. I have managed to boot to a Live CD version of Ubuntu 10.10 and have mounted the internal hard drive (which takes nearly 8 minutes). I suspect that the hard drive is malfunctioning, however, because copy tasks of even 30 megs of data to an attached and mounted USB flash drive takes over an hour, and some files are mysteriously inaccessible (not a permissions issue). When browsing folders, it takes many minutes to populate the folder window even with a single tiny file. During the copy tasks, the hard disk sounds like it tries to sleep several times in rapid succession, then continues accessing, it sounds, at full throughput. I initially tried using scp (from the shell) to copy data but I encountered the same local problems. I don't know the S.M.A.R.T. status of the hard disk, either. Is there a more effective way of going about recovering the data on the internal disk, assuming that I can't use a recovery CD and am too cheap to bring it in (for now, at least)?

• Nvidia GTX 660m crashes games

  - by dcap

  I just recently bought a Lenovo y580 with both HD intel graphics and an Nvidia GTX 660m. It works great except for one thing: playing games. Every time I load a game, either with Steam or Games for Windows Live, games will end up crashing. I've already talked with lenovo tech support and they couldn't help other than send my new laptop for repair which would take 7 days. So before I do that I thought I'd ask around. These are the games I've tested and what happens when they load: Civilization V: Game loads fine but once it gets loaded to the game, there's noticeable "tearing" popping up and certain things flash. Within a minute of this, the game crashes. Does the same thing regardless if Vsync is on or off. Total War Shogun2: Game gets to the menu screen. The background of the menu screen shows what is expected - slideshow of in-game environments rendered on high settings (this is expected). However, within 2 seconds of the menu loading up it crashes. Age of Empires 3 (Non-steam): This game is several years old so it should work on this brand new laptop fine. However the results are similar to that of Civilization V. Noticeable "Tearing" and after a few seconds it'll freeze/crash. I've done tests on all these games with both the latest stable Nvidia driver 285 as well as the nightly build 307. In addition, Nvidia control panel is set on using the dedicated graphics card for all programs. So is there anything I can do to fix this or will I have to send it back for a week to tech support?

• Google Chrome on Linux not using ALSA for sound

  - by DarkMoon

  On my laptop, I've got an .asoundrc file that outputs sound to my USB headset. This works fine for SMplayer and Firefox. However, Google Chrome (at least, Flash-based and HTML5-based videos and HTML5-based audio in Chrome) plays through the laptop speakers instead. I've tried running Chrome from a command-line, hoping there would be some helpful output, but no such luck. I've tried looking through Google for whether Chrome even uses ALSA, or if it uses something else, but I have been unsuccessful in this. This question seems to be the same issue, but no suggestion was made. Anyone have any ideas? I'm running Gentoo with a 3.10.17 kernel, 1.0.27 ALSA utils, 2.6.5 FVWM, and 36.0.1985.143 Chrome. If you need more info, please let me know. EDIT: I've configured the USB headset as the default ALSA device. Volume levels for both headset and onboard are set and un-muted using alsamixer. My .asoundrc file is as follows. ctl.!default { type hw card Headset } pcm.dmixer { type dmix ipc_key 1024 slave { pcm { type hw card Headset } period_size 1024 buffer_size 4096 } bindings { 0 0 1 1 } } pcm.!default { type plug slave.pcm dmixer }

• How to run a restricted set of programs with Administrator privileges without giving up Admin acces (Win7 Pro)

  - by frLich

  I have a shared system, running Windows7 X64, restricted to a 'standard user' with no password. Not everyone who has access to the system has the administrator password. This works rather well, except for some applications - specially the unlock-applications for encrypted hard drives/USB flash drives. The specific ones either require Administrator access (eg. Seagate Blackarmor) or simply fail without it -- since these programs are sending raw commands to a device, this is to be expected. I would like to be able to add the hashes of these particular programs to a whitelist, and have them run as administrator without needing any prompts. Since these are by definition on removable media, I can't simply use a filename or even a path. One of the users who shares the system can be considered 'crafty', so anything which temporarily grants administrator rights to an user account is certain to cause problems. What i'd like to be able to do: 1) Create an admin account that can only run programs from a whitelist (or, failing that, from a directory) I can't find a good way to do this: As far as I can tell, SRP applies equally to ALL users? Even if I put a "Deny" token on all directories on the system, such that new directories would inherit it, it could still potentially run things from the mounted USB devices. I also don't know whether it's possible to create a new directory that DOESN'T inherit from the parent, that would lake the deny token, and provide admin access. 2) Find a lightweight service that will run these programs in its local context Windows7 seems to block cross-privilege level communication by default, and I haven't found such for windows 7. One example seems to be "sudo" (http://pages.cpsc.ucalgary.ca/~nfriess/sudo/) but because it uses a WLNOTIFY hook, it won't work under Vista nor Windows7 Non-Solutions: - RunAs: Requires administrator password! (but everyone calls it "sudo" anyway) - SuRun: From Google: "Surun uses its own Windows service that adds the user to the group of administrators during program start and removes him automatically from that group again"

• Modifying value of "Rating" column within Explorer for arbitrary file types.

  - by Fake Name

  Basically, I have a large body of assorted media (text, images, flash files, archives, folders, etc...) and I'm attempting to organize it. Windows Explorer has a rating column, but there seems to be no way to modify the rating of the files short of opening them in their type-specific software (e.g. Media player, or Photo viewer). However, this does not work when the file is of an unsupported type (.rar, .swf ...), or a directory. I'd be more than willing to consider a file-manager replacement (I've alreadly looked at quite a few, Directory Opus, Total Commander, etc...), or even a solution that stores the rating metadata in a hidden file in each folder, or a separate database. The one real critical requirement is the ability to sort by rating, and being filetype-agnostic. Basically, is there any way to categorize a large collection of assorted files by rating that will work with any file type, including directories? - Ideally, there would be an easy way to add arbitrary columns to windows explorer, and edit them directly. However, there seems to be no way to do this. The rating column is the next best thing.

• netbook screen stays black

  - by sam113101

  I have an acer aspire one netbook. The screen is black but the computer turns on (LED's are on, fan is spinning, etc.) By black I mean absolutely no backlight. I tried to remove the battery and power it on to "discharge" it (I read that on the Internet, not sure if that ever fixes anything), but no luck. I also tried to replace the RAM stick with another one (which I know for sure is working properly), still no luck. I tried to connect an external monitor and switch to it (fn + f5 on this particular model), still no luck, nothing on the external monitor. I read that flashing the BIOS could fix it (http://community.spiceworks.com/how_to/show/22042-acer-aspire-one-black-screen-of-death), I tried to flash it but basically it doesn't do anything when I power it on with the usb thumb drive. No blinking power button. To me it sounds like it might be a dead motherboard, a dead RAM slot (there's only one), or the BIOS thing. I would like to rule out the BIOS possibility, but I need help. The reason I ruled out the dead screen possibility is that it did not switch to the external display when I pressed fn + f5, am I wrong by assuming so? Thank you for your help.

• Windows 8 Killed my SSDs

  - by SLaks

  I have a computer running 2 256GB Crucial M4's (CT256M4SSD2) in a RAID 0 (striped) array on an ASUS P9X79 Pro using Intel's (built-in) RAID system. I recently installed Windows 8 Pro as UEFI on this RAID array. (wiping a fully-function Windows 7 non-UEFI installation) Now, whenever the computer is left running for about an hour, the system no longer sees those drives. Since those drives contain Windows, this leads to various forms of BSODs. If I Intel RSTe (RAID manager) is running at the time, it will say that the disk backing that RAID array has been removed. Once this happens, if I reset the computer, it will no longer boot. Entering BIOS setup shows that the SATA 3 (6Gbps) ports that those disks are connected to are both empty. If I then power down the system completely, then turn it on again, the drives reappear, but the problem repeats after another hour or so. I have inconclusively determined that the problem occurs even if Windows is not running (booted into the installation environment from a UEFI flash drive) I don't think there has been any data corruption since this started happening, although I have had two strange issues with a GIT repo on that disk. sfc /ScanNow and Intel's disk check (in RSTe) both do not find anything. Does anyone know what might cause this?

• 100% CPU use when new usb device plugged in - services.exe / Windows Server 2003

  - by Will3265

  On my server I am trying to install a new usb drive but all that happens is that the system starts using huge amounts of processor cycles with services.exe. On closer inspection with process explorer there is a thread called umpnpmgr.dll using most of the services.exe processor time. I left it for a half hour and still nothing happened. Rebooted and tried again, same result. Tried a different usb drive, then a flash drive but still same issue. Tried updating driver but it said the update function was already in action. I have used process explorer to kill the thread now so the server can still perform its intended functions. Any device that was previously installed before this began happening will still work but any device new to the system will not. My question(s) is/are: Is there a way to manually install the device into the registry so Windows thinks it is a previously installed device? Or can this problem be repaired through anything other than a reinstall? To do a reinstall would mean backing up large amounts of data which is hard with a usb drive and insufficient space on all other network machines. Any help would be greatly appreciated. William

• Lots of first chance Microsoft.CSharp.RuntimeBinderExceptions thrown when dealing with dynamics

  - by Orion Edwards

  I've got a standard 'dynamic dictionary' type class in C# - class Bucket : DynamicObject { readonly Dictionary<string, object> m_dict = new Dictionary<string, object>(); public override bool TrySetMember(SetMemberBinder binder, object value) { m_dict[binder.Name] = value; return true; } public override bool TryGetMember(GetMemberBinder binder, out object result) { return m_dict.TryGetValue(binder.Name, out result); } } Now I call it, as follows: static void Main(string[] args) { dynamic d = new Bucket(); d.Name = "Orion"; // 2 RuntimeBinderExceptions Console.WriteLine(d.Name); // 2 RuntimeBinderExceptions } The app does what you'd expect it to, but the debug output looks like this: A first chance exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in Microsoft.CSharp.dll A first chance exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in Microsoft.CSharp.dll 'ScratchConsoleApplication.vshost.exe' (Managed (v4.0.30319)): Loaded 'Anonymously Hosted DynamicMethods Assembly' A first chance exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in Microsoft.CSharp.dll A first chance exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in Microsoft.CSharp.dll Any attempt to access a dynamic member seems to output a RuntimeBinderException to the debug logs. While I'm aware that first-chance exceptions are not a problem in and of themselves, this does cause some problems for me: I often have the debugger set to "break on exceptions", as I'm writing WPF apps, and otherwise all exceptions end up getting converted to a DispatcherUnhandledException, and all the actual information you want is lost. WPF sucks like that. As soon as I hit any code that's using dynamic, the debug output log becomes fairly useless. All the useful trace lines that I care about get hidden amongst all the useless RuntimeBinderExceptions Is there any way I can turn this off, or is the RuntimeBinder unfortunately just built like that? Thanks, Orion

  I've just set up my first Android development environment consisting of Eclipse 3.5 Mac OSX 10.5 Android SDK for x86 macs ADT Eclipse plugin 0.9.6 I've set set $PATH to my SDK/tools directory (which shouldn't matter if I only use Eclipse right?) and started Eclipse, but when I try to set the path to the SDK in Eclipse, i get the error "parseSdkContent failed".

Any ideas as to why this might fail?

• Mutual SSL Client Authentication

  - by nordisk

  Hi, I'm trying to achieve mutual SSL client authentication but without much success so far. Let me explain my scenario first: I have a client certificate issued by an intermediate CA whose certificate in turn was issued by a root CA (the intermediate and root CAs are within the company's network). This is the certificate I am including as part of my call to the server (using the HttpWebRequest object). The server has imported my client certificate and it is one of the certificates presented to me. An important thing to note is that the server does not trust the intermediate CA or the root for that matter. What we're trying to achieve is authentication against the certificate directly, i.e. mutual authentication using my client certificate. The error I'm getting is: "The request was aborted: Could not create SSL/TLS secure channel." From my trace logs I also get the following: System.Net Information: 0 : [3380] SecureChannel#34868631 - We have user-provided certificates. The server has specified 2 issuer(s). Looking for certificates that match any of the issuers. System.Net Information: 0 : [3380] SecureChannel#34868631 - Left with 0 client certificates to choose from. One of the certificates presented to us from the server is the same as our client certificate but the matching between them seems to fail. It looks like it's trying to verify the issuer. Now to make things even more interesting: If the server trusts and sends back the intermediate CA then everything works fine! (This is not an option for the production environment though I'm told) Using jmeter to test the request works fine too. I can only assume that Java's SSL handshake implementation is somewhat different. So it really comes down to this: Do you need to implement mutual SSL authentication differently from normal client SSL authentication? Any ideas or comments would be greatly appreciated.

• DevExpress AspxGridView clientside SelectionChanged problem when using paged ObjectDataSource

  - by Constantin Baciu

  The context is as follows: One DexExpress AspxGridView with a server-side paging/filtering/sorting mechanism (using ObjectDataSource). I've been having problems with the filter mechanism ( see this stack ). Now, the problem I'm having is this: the client-side events get mangled between DataSource events. :O . Let me explain what happens: if I change the page (or sort/filter for that matter), then, select one row from the grid, the client-side SelectionChanged event fires well. If I change the page (or sort/filter), the event doesn't fire anymore.

• How to troubleshoot errors with TeamCity

  - by Tomas Lycken

  I'm following this guide to set up a small environment for source control and automated builds - mostly for learning what it is and how it works, but also for using in those of my hobby projects that I believe will actually be useful some day. However, at the step where he commits and builds, I fail to get a success status in the TeamCity history log. I keep getting the error described in the stack trace below. I have verified with Windows Explorer that the solution file it can't find is actually there, so I really don't know what to do. How do I fix/troubleshoot this?

• What good technology podcasts are out there?

  - by Michael Stum

  Yes, Podcasts, those nice little Audiobooks I can listen to on the way to work. With the current amount of Podcasts, it's like searching a needle in a haystack, except that the haystack happens to be the Internet and is filled with too many of these "Hot new Gadgets" stuff :( Now, even though I am mainly a .NET developer nowadays, maybe anyone knows some good Podcasts from people regarding the whole software lifecycle?

• Exception converting Office files to PDF using ABCpdf.NET onWindows Server 2008

  - by drivendevelopment

  Has anyone delt with this exception from ABCpdf? We're running on Server 2008 and only have issues converting Office files (Word and Excel). This all worked well on Server 2003. Because we're only having issues with Office files I wonder if it's related to the XPS support on Server 2008? The code that calls into this function is running as a Windows Service. Private Overloads Function ConvertMicrosoftOfficeDocToPdf(ByVal inputFile As Byte(), ByVal fileExt As String) As Byte() Dim abcDoc As WebSupergoo.ABCpdf7.Doc = Nothing Try abcDoc = New WebSupergoo.ABCpdf7.Doc() Dim xro As New WebSupergoo.ABCpdf7.XReadOptions() xro.FileExtension = fileExt Try abcDoc.Read(inputFile, xro) Catch ex As Exception System.Diagnostics.Trace.Write(ex.ToString()) Throw ex End Try Dim fileBytes As Byte() = abcDoc.GetData() Return fileBytes Finally If Not abcDoc Is Nothing Then abcDoc.Clear() abcDoc.Dispose() End If End Try End Function WebSupergoo.ABCpdf7.Internal.PDFException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. --- System.AccessViolationException: Attempted to read or write protected memory.

• Getting warning about sensitive information that could be disclosed to 3rd parties - Asp.net MVC 2.0

  - by chobo2

  Hi I never gotten this message before I started to use asp.net mvc 2.0 and jquery 1.4. <title>This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.</title> <span><H1>Server Error in '/' Application.<hr width=100% size=1 color=silver></H1> <h2> <i>This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request.

What I was trying to send back was a rendered string of a partial view(http://www.klopfenstein.net/lorenz.aspx/render-partial-view-to-string-in-asp-net-mvc) and a success msg.

• How to change StartupUri of WPF Application?

  - by Akash Kava

  I am trying to modify App.cs and load the WPF XAML files from code behind but its not working as it should. No matter whatever I try to set as StartupUri it doesnt start, the program quits after this. public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); LoginDialog dlg = new LoginDialog(); if (dlg.ShowDialog() != true) return; switch (dlg.ChoiceApp) { case ChoiceApp.CustomerEntry: StartupUri = new Uri("/MyApp;component/Forms/CustomerEntry.xaml", UriKind.Relative); break; case ChoiceApp.VendorEntry: StartupUri = new Uri("/MyApp;component/Forms/VendorEntry.xaml", UriKind.Relative); break; } } } Now I even did trace and found out that LoginDialog is working correctly and is returning values correctly but setting "StartupUri" does not work. I checked in reverse assembly that DoStartup method of App gets called after OnStartup, so technically my StartupUri must load, but it doesnt, in App.xaml startup uri is not at all defined. Note: Bug Confirmed I noticed that ShowDialog sets Application.MainWindow and when dialog ends, it sets it back to null, and because of this setting StartupUri does not work after calling Modal Dialog in OnStartup or Startup event. There is no error or exception about invalid uri or anything like that. This method works without DialogBox being called in Startup event or OnStartup, i think calling showdialog on this method causes something like its mainwindow being set to expired window and it shuts down after this.

• PDF rendering crashes app Core Graphics

  - by Felixyz

  EDIT: The memory leaks turned out to be unrelated to the crashes. Leaks are fixed but crashes remain, still mysterious. My (iPhone) app does lots of PDF loading and rendering, some of it threaded. Sometime, it seems always after I flush a page cash after getting a memory warning, the app crashes with a bad access when trying to draw a pdf page stored in an NSData object. Here is one example trace: #0 0x3016d564 in CGPDFResourcesGetResource () #1 0x3016d58a in CGPDFResourcesGetResource () #2 0x3016d94e in CGPDFResourcesGetExtGState () #3 0x3015fac4 in CGPDFContentStreamGetExtGState () #4 0x301629a8 in op_gs () #5 0x3016df12 in handle_xname () #6 0x3016dd9e in read_objects () #7 0x3016de6c in CGPDFScannerScan () #8 0x30161e34 in CGPDFDrawingContextDraw () #9 0x3016a9dc in CGContextDrawPDFPage () But sometimes I get this instead: Program received signal: “EXC_BAD_ACCESS”. (gdb) bt #0 0x335625fa in objc_msgSend () #1 0x32c04eba in CFDictionaryGetValue () #2 0x3016d500 in get_value () #3 0x3016d5d6 in CGPDFResourcesGetFont () #4 0x3015fbb4 in CGPDFContentStreamGetFont () #5 0x30163480 in op_Tf () #6 0x3016df12 in handle_xname () #7 0x3016dd9e in read_objects () #8 0x3016de6c in CGPDFScannerScan () #9 0x30161e34 in CGPDFDrawingContextDraw () #10 0x3016a9dc in CGContextDrawPDFPage () Is this an indication that I've mistakenly deallocated an object? It's hard for me to decode what's happening here. This is how I create and retain the various objects involved: // Some data was just loaded from the network and is pointed to by "data" self.pdfData = data; _dataProviderRef = CGDataProviderCreateWithData( NULL, [_pdfData bytes], [_pdfData length], NULL ); _documentRef = CGPDFDocumentCreateWithProvider(_dataProviderRef); _pageRef = CGPDFDocumentGetPage(_documentRef, 1); CGPDFPageRetain(_pageRef); _pdfFrame = CGPDFPageGetBoxRect(_pageRef, kCGPDFArtBox); So the NSData object is retained, and I explicitly retain the page reference. The data provider and the document are already retained by the create-functions. And here is my dealloc method: -(void)dealloc { if (_pageRef) CGPDFPageRelease(_pageRef); if (_documentRef) CGPDFDocumentRelease(_documentRef); if (_dataProviderRef) CGDataProviderRelease(_dataProviderRef); self.pdfData = nil; [super dealloc]; } Am I doing anything wrong? Even an assurance that I'm not, with explanation, would be a help.

• .NET "must-have" development tools

  - by nzpcmad

  James Avery wrote a classic article a while back entitled Ten Must-Have Tools Every Developer Should Download Now which is a companion to Visual Studio Add-Ins Every Developer Should Download Now and Scott Hanselman has an excellent list on his blog but if you were on a desert island and were only allowed three .NET development tools which ones would you pick? Update: Assuming you already have an IDE like Visual Studio ... Update (5) : Up to 08/01 : The current state of play: Reflector 13 Resharper 9 NUnit + TestDriven.Net 7 Refactor Pro 4 Process Explorer (other Sysinternals) 3 SnippetCompiler 3 CodeRush 3 MSDN Library 2 LinqPad 2 Cruisecontrol.net 2 VMWare 2 RhinoMocks 2 Fiddler 2 PowerShell 2 PowerCommands for VS 2008 1 Sandcastle 1 SQL Profiler 1 Redgate ANTS profiler 11 NCover 1 VisualSVN 1 Rubber Ducky 1 WinMerge 1 NAnt 1 ViEmu 1 AnkhSVN 1 dotTrace Profiler 1 BeyondCompare 1 DPack VS Plugin 1 WCF Trace Viewer (SDK) 1 xUnit.net 1 SourceGear DiffMerge 1 Ghostdoc 1 Expression Studio 1 XAML Pad 1 KaXaml 1 Blender for 3D modeling 1 Snoop a WPF tool 1 DiffMerge 1 DPack 1 NDepend 1 Kodos 1 WatiN 1 HTTPWatch Basic Edition 1 Paint.Net 1 Mole For VS 1 What I find particularly interesting about this is that "NUnit + TestDriven.Net " is right up there in third place which shows the growing emphasis on testing as an integral part of the development process rather than as an adjunct which is simply bolted on. And I'm somewhat perplexed that Codesmith didn't receive a single vote?
