  • How to fix winlogon.exe randomly crashing/hanging my computer?

    - by Neeb
    I've got these problems: 1) sometimes winlogon.exe crashes at boot-up and my whole computer shuts off once i click "no" to visual-studio-2008 just-in-time-debugger window, takes about 30 secs until my harddrives starts up again, its really scary, i am afraid it is causing hardware malfunctions in long term. this has happened dozen of time now. 2) sometimes i leave the computer alone a while, i come back and i notice ctrl+alt+del doesnt work and winlogon.exe is using 100% of one of my 4 cores.

  • Cannot enable wireless Ubuntu 10.04

    - by woaddoa
    I have recently installed Ubuntu 10.04, however I am having trouble getting wireless to work. Ubuntu says that wireless is disabled, and I am unable to enable it. I have tried Administration Hardware Drivers however the only drivers listed are Nivida graphics ones. I am unsure what to do as I do not think the process is the same as searching for drivers for a windows machine. Any advice appreciated.

  • How to set up a home SIP Server/Proxy for multi ring?

    - by zio
    I have a sip account which only allows one device to be registered. When i'm at home I want incoming calls to be able to ring on multiple devices. All of these devices are connected to the local network. I'm guessing the way to do this is using a local server/proxy that would allow multiple registrations which then forwards traffic to/from my sip provider. What a simple way to do this on either OS X, Ubuntu or using some low cost SIP router hardware?

  • Windows 7 Error Recovery upon boot

    - by nijikunai
    My system doesn't boot at all, upon starting it takes me to the Windows Error Recovery screen saying "Windows failed to start, a recent software or hardware change might be the cause" and gives two options Launch System Repair (Recommended) Start Windows normally But neither options work, upon clicking either of them, some progress bars get displayed and the screen just freezes on "Starting Windows". I tried booting from the Windows 7 disk but it too freezes on the "Starting Windows" screen. I even tried booting from ubuntu, slax linux, but they don't work too.

  • Will any USB DVD reader work with Apple Mac's?

    - by Kev
    Following on from this question: Can Apple Macintosh computers boot from a USB volume? Can I use any USB 2.0 DVD drive to boot a Mac from? I had a look around my local PC World today and only the more expensive drives explicitly state on the packaging that they were Mac compatible. Is this just because these products have been through Apple's hardware approval/testing programme, or do Mac's have some special requirement?

  • Accessing temperature data on ESXi5.1?

    - by Ovesh
    For ESXi5.1 (VMWare vSphere) images, I can see temperature data on the vSphere user interface (under Monitor / Hardware Status). I tried scouring the available snmp data using snmpwalk, but can't find the data anywhere in there. Maybe I'm missing something. Does anybody know the right MIB for temperature data? Otherwise, ow can that data be accessed? By the way, this is a machine installed from an image provided by HP.

  • Quick method to determine SSD drive health?

    - by ewwhite
    I have an Intel X-25M drive that was marked "failed" twice in a ZFS storage array, as noted here. However, after removing the drive, it seems to to mount, read and write in other computers (Mac, PC, USB enclosure, etc.) Is there a good way to determine the drive's present health? I feel that the previous failure in the ZFS solution was the convergence of bugs, bad error reporting and hardware. It seems like this drive may have some life in it, though.

  • Fast multi-window rendering with C#

    - by seb
    I've been searching and testing different kind of rendering libraries for C# days for many weeks now. So far I haven't found a single library that works well on multi-windowed rendering setups. The requirement is to be able to run the program on 12+ monitor setups (financial charting) without latencies on a fast computer. Each window needs to update multiple times every second. While doing this CPU needs to do lots of intensive and time critical tasks so some of the burden has to be shifted to GPUs. That's where hardware rendering steps in, in another words DirectX or OpenGL. I have tried GDI+ with windows forms and figured it's way too slow for my needs. I have tried OpenGL via OpenTK (on windows forms control) which seemed decently quick (I still have some tests to run on it) but painfully difficult to get working properly (hard to find/program good text rendering libraries). Recently I tried DirectX9, DirectX10 and Direct2D with Windows forms via SharpDX. I tried a separate device for each window and a single device/multiple swap chains approaches. All of these resulted in very poor performance on multiple windows. For example if I set target FPS to 20 and open 4 full screen windows on different monitors the whole operating system starts lagging very badly. Rendering is simply clearing the screen to black, no primitives rendered. CPU usage on this test was about 0% and GPU usage about 10%, I don't understand what is the bottleneck here? My development computer is very fast, i7 2700k, AMD HD7900, 16GB ram so the tests should definitely run on this one. In comparison I did some DirectX9 tests on C++/Win32 API one device/multiple swap chains and I could open 100 windows spread all over the 4-monitor workspace (with 3d teapot rotating on them) and still had perfectly responsible operating system (fps was dropping of course on the rendering windows quite badly to around 5 which is what I would expect running 100 simultaneous renderings). Does anyone know any good ways to do multi-windowed rendering on C# or am I forced to re-write my program in C++ to get that performance (major pain)? I guess I'm giving OpenGL another shot before I go the C++ route... I'll report any findings here. Test methods for reference: For C# DirectX one-device multiple swapchain test I used the method from this excellent answer: Display Different images per monitor directX 10 Direct3D10 version: I created the d3d10device and DXGIFactory like this: D3DDev = new SharpDX.Direct3D10.Device(SharpDX.Direct3D10.DriverType.Hardware, SharpDX.Direct3D10.DeviceCreationFlags.None); DXGIFac = new SharpDX.DXGI.Factory(); Then initialized the rendering windows like this: var scd = new SwapChainDescription(); scd.BufferCount = 1; scd.ModeDescription = new ModeDescription(control.Width, control.Height, new Rational(60, 1), Format.R8G8B8A8_UNorm); scd.IsWindowed = true; scd.OutputHandle = control.Handle; scd.SampleDescription = new SampleDescription(1, 0); scd.SwapEffect = SwapEffect.Discard; scd.Usage = Usage.RenderTargetOutput; SC = new SwapChain(Parent.DXGIFac, Parent.D3DDev, scd); var backBuffer = Texture2D.FromSwapChain<Texture2D>(SC, 0); _rt = new RenderTargetView(Parent.D3DDev, backBuffer); Drawing command executed on each rendering iteration is simply: Parent.D3DDev.ClearRenderTargetView(_rt, new Color4(0, 0, 0, 0)); SC.Present(0, SharpDX.DXGI.PresentFlags.None); DirectX9 version is very similar: Device initialization: PresentParameters par = new PresentParameters(); par.PresentationInterval = PresentInterval.Immediate; par.Windowed = true; par.SwapEffect = SharpDX.Direct3D9.SwapEffect.Discard; par.PresentationInterval = PresentInterval.Immediate; par.AutoDepthStencilFormat = SharpDX.Direct3D9.Format.D16; par.EnableAutoDepthStencil = true; par.BackBufferFormat = SharpDX.Direct3D9.Format.X8R8G8B8; // firsthandle is the handle of first rendering window D3DDev = new SharpDX.Direct3D9.Device(new Direct3D(), 0, DeviceType.Hardware, firsthandle, CreateFlags.SoftwareVertexProcessing, par); Rendering window initialization: if (parent.D3DDev.SwapChainCount == 0) { SC = parent.D3DDev.GetSwapChain(0); } else { PresentParameters pp = new PresentParameters(); pp.Windowed = true; pp.SwapEffect = SharpDX.Direct3D9.SwapEffect.Discard; pp.BackBufferFormat = SharpDX.Direct3D9.Format.X8R8G8B8; pp.EnableAutoDepthStencil = true; pp.AutoDepthStencilFormat = SharpDX.Direct3D9.Format.D16; pp.PresentationInterval = PresentInterval.Immediate; SC = new SharpDX.Direct3D9.SwapChain(parent.D3DDev, pp); } Code for drawing loop: SharpDX.Direct3D9.Surface bb = SC.GetBackBuffer(0); Parent.D3DDev.SetRenderTarget(0, bb); Parent.D3DDev.Clear(ClearFlags.Target, Color.Black, 1f, 0); SC.Present(Present.None, new SharpDX.Rectangle(), new SharpDX.Rectangle(), HWND); bb.Dispose(); C++ DirectX9/Win32 API test with multiple swapchains and one device code is here: http://pastebin.com/tjnRvATJ It's a modified version from Kevin Harris's nice example code.

  • How to associate Wi-Fi beacon info with a virtual "location"?

    - by leander
    We have a piece of embedded hardware that will sense 802.11 beacons, and we're using this to make a map of currently visible bssid -> signalStrength. Given this map, we would like to make a determination: Is this likely to be a location I have been to before? If so, what is its ID? If not, I should remember this location: generate a new ID. Now what should I store (and how should I store it) to make future determinations easier? This is for an augmented-reality app/game. We will be using it to associate particular characters and events with "locations". The device does not have internet or cellular access, so using a geolocation service is out of consideration for the time being. (We don't really need to know where we are in reality, just be able to determine if we return there.) It isn't crucial that it be extremely accurate, but it would be nice if it was tolerant to signal strength changes or the occasional missing beacon. It should be usable in relatively low numbers of access points (e.g. rural house with one wireless router) or many (wandering around a dense metropolis). In the case of a city, it should change location every few minutes of walking (continuously-overlapping signals make this a bit more tricky in naive code). A reasonable number of false positives (match a location when we aren't actually there) is acceptable. The wrong character/event showing up just adds a bit of variety. False negatives (no location match) are a bit more troublesome: this will tend to add a better-matching new location to the saved locations, masking the old one. While we will have additional logic to ensure locations that the device hasn't seen in a while will "orphan" any associated characters or events (if e.g. you move to a different country), we'd prefer not to mask and eventually orphan locations you do visit regularly. Some technical complications: signalStrength is returned as 1-4; presumably it's related to dB, but we are not sure exactly how; in my experiments it tends to stick to either 1 or 4, but occasionally we see numbers in between. (Tech docs on the hardware are sparse.) The device completes a scan of one-quarter of the channel space every second; so it takes about 4-5 seconds to get a complete picture of what's around. The list isn't always complete. (We are making strides to fix this using some slight sampling period randomization, as recommended by the library docs. We're also investigating ways to increase the number of scans without killing our performance; the hardware/libs are poorly behaved when it comes to saturating the bus.) We have only kilobytes to store our history. We have a "working" impl now, but it is relatively naive, and flaky in the face of real-world Wi-Fi behavior. Rough pseudocode: // recordLocation() -- only store strength 4 locations m_savedLocations[g_nextId++] = filterForStrengthGE( m_currentAPs, 4 ); // determineLocation() bestPoints = -inf; foreach ( oldLoc in m_savedLocations ) { points = 0.0; foreach ( ap in m_currentAPs ) { if ( oldLoc.has( ap ) ) { switch ( ap.signalStrength ) { case 3: points += 1.0; break; case 4: points += 2.0; break; } } } points /= oldLoc.numAPs; if ( points > bestPoints ) { bestLoc = oldLoc; bestPoints = points; } } if ( bestLoc && bestPoints > 1.0 ) { if ( bestPoints >= (2.0 - epsilon) ) { // near-perfect match. // update location with any new high-strength APs that have appeared bestLoc.addAPs( filterForStrengthGE( m_currentAPs, 4 ) ); } return bestLoc; } else { return NO_MATCH; } We record a location currently only when we have NO_MATCH and the app determines it's time for a new event. (The "near-perfect match" code above would appear to make it harder to match in the future... It's mostly to keep new powerful APs from being associated with other locations, but you'd think we'd need something to counter this if e.g. an AP doesn't show up in the next 10 times I match a location.) I have a feeling that we're missing some things from set theory or graph theory that would assist in grouping/classification of this data, and perhaps providing a better "confidence level" on matches, and better robustness against missed beacons, signal strength changes, and the like. Also it would be useful to have a good method for mutating locations over time. Any useful resources out there for this sort of thing? Simple and/or robust approaches we're missing?

  • What is Causing This Memory Leak in Delphi?

    - by lkessler
    I just can't figure out this memory leak that EurekaLog is reporting for my program. I'm using Delphi 2009. Here it is: Memory Leak: Type=Data; Total size=26; Count=1; The stack is: System.pas _UStrSetLength 17477 System.pas _UStrCat 17572 Process.pas InputGedcomFile 1145 That is all there is in the stack. EurekaLog is pointing me to the location where the memory that was not released was first allocated. According to it, the line in my program is line 1145 of InputGedcomFile. That line is: CurStruct0Key := 'HEAD' + Level0Key; where CurStruct0Key and Level0Key are simply defined in the procedure as local variables that should be dynamically handled by the Delphi memory manager when entering and leaving the procedure: var CurStruct0Key, Level0Key: string; So now I look at the _UStrCat procedure in the System Unit. Line 17572 is: CALL _UStrSetLength // Set length of Dest and I go to the _UStrSetLength procedure in the System Unit, and the relevant lines are: @@isUnicode: CMP [EAX-skew].StrRec.refCnt,1 // !!! MT safety JNE @@copyString // not unique, so copy SUB EAX,rOff // Offset EAX "S" to start of memory block ADD EDX,EDX // Double length to get size JO @@overflow ADD EDX,rOff+2 // Add string rec size JO @@overflow PUSH EAX // Put S on stack MOV EAX,ESP // to pass by reference CALL _ReallocMem POP EAX ADD EAX,rOff // Readjust MOV [EBX],EAX // Store MOV [EAX-skew].StrRec.length,ESI MOV WORD PTR [EAX+ESI*2],0 // Null terminate TEST EDI,EDI // Was a temp created? JZ @@exit PUSH EDI MOV EAX,ESP CALL _LStrClr POP EDI JMP @@exit where line 17477 is the "CALL _ReallocMem" line. So then what is the memory leak? Surely a simple concatenate of a string constant to a local string variable should not be causing a memory leak. Why is EurekaLog pointing me to the ReallocMem line in a _UStrSetLength routine that is part of Delphi? This is Delphi 2009 and I am using the new unicode strings. Any help or explanation here will be much appreciated.

I don't know for certain, but I think my counter-party is using some form of Java. <soap-env:Header> <wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext"> <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> <ds:SignedInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> <ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#" /> <ds:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1" /> <ds:Reference URI="#secinfo"> <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> <ds:DigestValue>xxxxxxxxxxxxx</ds:DigestValue> <ds:Transforms> <ds:Transform Algorithm="http://www.w3.org/TR/1999/REC-xpath-19991116"> <ds:XPath>//*[@id='secinfo']/child::*/text()</ds:XPath> </ds:Transform> </ds:Transforms> </ds:Reference> </ds:SignedInfo> <ds:SignatureValue>xxxxxxxxxxds:SignatureValue> <ds:KeyInfo> <ds:KeyName>xxxxxxx</ds:KeyName> </ds:KeyInfo> </ds:Signature> <t:UsernameToken xmlns:t="http://schemas.xmlsoap.org/ws/2002/04/secext" id="secinfo"> <t:UserInfo>USER=xxxx;CORR=xxxx;TIMESTAMP=201003161916</t:UserInfo> </t:UsernameToken> </wsse:Security> </soap-env:Header>

    - by Greener
    Hello, I am using HMLHttpRequest object to retrieve information from the database via servlet and populate combo box. The code run in Firefox 3.6 and Chrome without any problems. However, I have a problem with IE 8. here is my code: var req; var isIE; function initRequest(){ if (window.XMLHttpRequest) { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { isIE = true; req = new ActiveXObject("Microsoft.XMLHTTP"); } } function populateMuniBox(countyCode) { initRequest(); req.onreadystatechange = populateMuniCallback; req.open("GET","./CntyMuni?county="+ countyCode,true); req.send(null); } function populateMuniCallback() { //clean combo box document.getElementById("cmbMuni").options.length = 0; var muni; if(req.readyState==4){ if (req.status == 200){ var XMLresult = req.responseXML; var muni = XMLresult.getElementsByTagName("rec"); } } for(var i=0;i<muni.length;i++) { //create Html option Element var opt = document.createElement("option"); //Set up the option - add values from XML opt.value = muni[i].getAttribute("code"); opt.text = muni[i].getAttribute("desc"); //add the option to the combobox document.getElementById("cmbMuni").appendChild(opt); } } HMTL code //First combo box the sends a value to the script <td> <select name="cn" id="county" onchange="populateMuniBox(this.value)"> // Second cmb <select name="mu" id="cmbMuni" ></select> IE error: 'lenght' is null or not an object cntymuni.jsp Code: 0 I am not sure how to fix the error.

  • Rails, RSpec and Webrat: Expected output matches rendered output but still getting error in view spe

    - by Anthony Burns
    Hello all, I've just gotten started using BDD with RSpec/Cucumber/Webrat and Rails and I've run into some frustration trying to get my view spec to pass. First of all, I am running Ruby 1.9.1p129 with Rails 2.3.2, RSpec and RSpec-Rails 1.2.6, Cucumber 0.3.11, and Webrat 0.4.4. Here is the code relevant to my question config/routes.rb: map.b_posts 'backend/posts', :controller => 'backend/posts', :action => 'backend_index', :conditions => { :method => :get } map.connect 'backend/posts', :controller => 'backend/posts', :action => 'create', :conditions => { :method => :post } views/backend/posts/create.html.erb: <% form_tag do %> <% end %> *spec/views/backend/posts/create.html.erb_spec.rb:* describe "backend/posts/create.html.erb" do it "should render a form to create a post" do render "backend/posts/create.html.erb" response.should have_selector("form", :method => 'post', :action => b_posts_path) do |form| # Nothing here yet. end end end Here is the relevant part of the output when I run script/spec: 'backend/posts/create.html.erb should render a form to create a post' FAILED expected following output to contain a <form method='post' action='/backend/posts'/> tag: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><form action="/backend/posts" method="post"> </form></body></html> It would appear to me that what have_selector is looking for is exactly what the template generates, yet the example still fails. I am very much looking forward to seeing my error (because I have a feeling it is my error). Any help is much appreciated!

  • Frameset isn't working in IE

    - by Cameroon
    First of all, why use a frame set in the first place you ask? answer: Because my boss told me. That been said, I have 2 files. Index.html and Head.html. Contents of index.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/frameset.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Site Title</title> </head> <frameset rows="122,*" FRAMEBORDER=NO FRAMESPACING=2 BORDER=0> <frame name="t" src="head.html" scrolling="no" marginheight="0" marginwidth="0"> <frame name="b" src="http://www.website.com"> </frameset> <noframes> <p>You have frames turned off on your browser, please turn it on and reload this page.</p> </noframes> </html> Contents of head.html: <div style="border-bottom:2px solid #000;height:120px"> <center>This is the frame head.</center> </div> The code works fine in all browsers except Internet Explorer 7 and 8 (I don't care about 6). Is there anything I am doing wrong, and if not then can the same effect be achieved without frames and if so how?

  • F#: Tell me what I'm missing about using Async.Parallel

    - by JBristow
    ok, so I'm doing ProjectEuler Problem #14, and I'm fiddling around with optimizations in order to feel f# out. in the following code: let evenrule n = n / 2L let oddrule n = 3L * n + 1L let applyRule n = if n % 2L = 0L then evenrule n else oddrule n let runRules n = let rec loop a final = if a = 1L then final else loop (applyRule a) (final + 1L) n, loop (int64 n) 1L let testlist = seq {for i in 3 .. 2 .. 1000000 do yield i } let getAns sq = sq |> Seq.head let seqfil (a,acc) (b,curr) = if acc = curr then (a,acc) else if acc < curr then (b,curr) else (a,acc) let pmap f l = seq { for a in l do yield async {return f a} } |> Seq.map Async.RunSynchronously let pmap2 f l = seq { for a in l do yield async {return f a} } |> Async.Parallel |> Async.RunSynchronously let procseq f l = l |> f runRules |> Seq.reduce seqfil |> fst let timer = System.Diagnostics.Stopwatch() timer.Start() let ans1 = testlist |> procseq Seq.map // 837799 00:00:08.6251990 printfn "%A\t%A" ans1 timer.Elapsed timer.Reset() timer.Start() let ans2 = testlist |> procseq pmap printfn "%A\t%A" ans2 timer.Elapsed // 837799 00:00:12.3010250 timer.Reset() timer.Start() let ans3 = testlist |> procseq pmap2 printfn "%A\t%A" ans3 timer.Elapsed // 837799 00:00:58.2413990 timer.Reset() Why does the Async.Parallel code run REALLY slow in comparison to the straight up map? I know I shouldn't see that much of an effect, since I'm only on a dual core mac. Please note that I do NOT want help solving problem #14, I just want to know what's up with my parallel code.
