• How to bypass resume from hibernate [closed]

  - by Daniel Trebbien

  I am attempting to resume a Windows Vista laptop from hibernate, but the resume process seems to be stuck in an endless loop in which Windows is repeatedly trying to read from the optical drive. When I press the Power On button on the laptop, the screen is black (not even the backlight turns on) and the following occurs in a loop: Five seconds pass and I hear the optical drive being accessed. (There's no disk in the drive, so it sounds like a short buzzing noise.) Two seconds pass and I hear the optical drive being accessed. Two seconds pass and I hear the optical drive being accessed. So it's three short buzzing noises in a row, over and over again. Eventually I have to abruptly power off the machine. I have tried inserting a data CD into the drive as well as a bootable CD (a live Linux distro boot disk). For both, the optical drive spins up for a bit, but stops after Windows decides that the disk is not what it is looking for. I have since lost the Windows Vista recovery DVD, but I don't know if inserting the recovery disk into the optical drive would have a different effect than the bootable CD. I have tried pressing F8 immediately after pressing the Power On button (hoping to enter System Restore), but that did not have an effect. Is there a special key sequence that will cause Windows to bypass resuming from hibernate, effectively ignoring hiberfil.sys?

• Is it possible to mount a disk image, created with dd, to a directory on a mounted external usb hdd?

  - by Keeper Hood

  I have an image of my home (/dev/sda3) partition, which I've created using the "dd" command. dd if=/dev/sda3 of=/path/to/disk.img I've deleted the home partition via gparted in order to enlarge my /dev/root partition. Then I've recreated the /dev/sda3 partition which is smaller in size then the one I've backed up to the image. I was wondering since I have a 2TB external HDD, could it be possible to mount my backed up image on the external HDD and then copy the files into the /home directory. Since the external HDD would be already in a "mounted state", I'm unsure whether this is a good idea, mounting on a mounted device. I'm running Slackware 13.37 (64bit). used ext4 on all the partitions. resized the root partition with gparted live cd. I've tried mount -t ext4 /path/to/disk.img /mng/image -o loop It gave me an fs error (wrong fs type, bad option, bad superblock on dev/loop/0) Then i did dmesg | tail which outputs: EXT4-fs (loop0) : bad geometry: block count 29009610 exceeds size of defice (1679229 blocks) I have no idea what to do, I want to restore my /home data from the image I've backed up.

• Audio card with built-in ground isolator?

  - by Dave Jarvis

  What audio cards would you recommend that eliminate hum, and hard-drive & mouse movement signal interference? Hardware components: Motherboard. Asus P5Q SE Audio. Realtek ALC 1200, 8-Channel High-Definition Audio CODEC (on board) Harddrive. WD Caviar 320 GB Mouse. Logitech Marbleman USB Mixer. Mackie d.4 Pro Amplifier. Sonance Sonamp 260 All components are plugged into the same Monster Power HDP 910 powerbar (does not help eliminate noise). I have no other components plugged in. The computer uses a Monster iCable 1000 to go from mini (on board audio) to RCA (mixer). I have moved the cable as far from other cables as possible. A ground loop isolator between the mixer and on board audio eliminates all noise. I would rather not use a ground loop isolator; an internal audio card that is Linux-compatible (Kubuntu) would be ideal. Suggestions?

• Can't connect to public WiFi with MacBookPro at coffee shops and libraries

  - by Nathan Bowers

  The Problem: I can't connect to public, unencrypted WiFi at my local public library or Peets Coffee. My Setup: Late 2006 MacBookPro running 10.5.8. I have Parallels installed. It's supposed to work like this: 1) Connect to their unencrypted WiFi network 2) Open a browser which redirects you to their "enter password/agree to terms" page. 3) Browse normally. I can connect to the WiFi network, but when I try to authenticate I always get stuck in a redirect loop. It's been like this for a while. Even before I upgraded to 10.5.8. I never have trouble with encrypted networks or regular open WiFi. What I've tried: Disabling Parallels connections in Network Prefs. Superstition: somehow Parallels installed something in the network stack that's messing me up. Pinging the IP address of the WiFi node I'm connected to. I can ping it, it's there, but I still get stuck in this authentication redirect loop. Tried different browsers, tried different cookie and security settings. Even tried IE under Parallels. No dice. Tried flushing DNS cache. Asked library and coffee employees for help. It didn't go well. My Question: Anybody else have this problem? What should I be looking for?

• Process files in a folder that haven't previously been processed

  - by Paul

  I have a series of files in a directory that I need to carry an action out on using a script. Once the action is done, then I want to keep a log that the file has been processed, so that the next time the script is run, it does not attempt to carry out the action again. So lets say I can find all the files that should be processed like this: for i in `find /logfolder -name '20*.log'` ; do process_log $i echo $i >> processedlogsfile done So I have a file containing the logs I have processed, and my goal would be to modify the for loop such that these processed logs are not processed a second time. Doing a manual scan each time seems inefficient, particularly as the processedlogfiles gets bigger: if grep -iq "$i" processdlogfiles ; then continue; fi It would be good if these files could be excluded when setting up the for loop. Note that the OS in question is a linux derivative, a managment appliance, with a limited toolset (no attr command for example) and so no way to install additional utilities (well it is possible but not an option). Most common bash shell commands are available though. Also, the filenames and locations of the processed files must remain where they are - they can't be altered to reflect their processed status

• Vista won't boot. BSOD: Page fault in nonpaged area

  - by user31576

  Here's the story: I let Windows Update do the updates it wanted to do, then rebooted the computer. The updating process was taking time so I went away. When I came back, my computer was rebooting. It got as far as the Windows logo with the laoding bar. BSOD'd. Rebooted. And I'm stuck in this loop ever since. Looked up on the net, the "Page fault in nonpaged area" seems to be linked to faulty RAM or drivers. So I ran a memory test, it found no error. When I try in safe mode (with promt) I can see a list of drivers being loaded, then I get the same BSOD. I tried to repair using the Vista DVD, it says "nothing to repair". I tried to restore to a previous state, it says "no restore point found". So, my guess is, it's got something to do with the drivers. How can I identify the one causing the BSOD? If you have any other leads, What can I do? By the way, I'm writing from this very computer, running a linux distro I installed after the BSOD loop started. So i guess it's not an hardware issue. I have backed up important data, and will format and reinstall Windows if I must. But I'd like to avoid that. Thanks in advance for any help you can give me.

• What's wrong with my .htaccess? Trying to simplify actual code

  - by AlexV

  This is my actual .htaccess: #If the requested URI does not end with an extension RewriteCond %{REQUEST_URI} !\.(.*) #If the requested URI is not in an excluded location RewriteCond %{REQUEST_URI} !^/(excluded1|excluded2)/ #Then serve the URI via the mapper RewriteRule .* /seo-urls/seo-urls-mapper.php?uri=%{REQUEST_URI} [L,QSA] #If the requested URI ends with .php* RewriteCond %{REQUEST_URI} \.php.*$ [NC] #If the requested file is not seo-urls-mapper.php (avoid .htaccess loop) RewriteCond %{REQUEST_FILENAME} (?<!seo-urls-mapper)\.php.*$ #Then serve the URI via the mapper RewriteRule .* /seo-urls/seo-urls-mapper.php?uri=%{REQUEST_URI} [L,QSA] Since all conditions are compatibles except the 1st ones (no extension and *.php* match) all I should have to do is to add the [OR] condition to these 2 lines, but when I'm adding it it's not working (my no extension rule don't work anymore). This is my new (not working) code: #If the requested URI does not end with an extension OR if the URI ends with .php* RewriteCond %{REQUEST_URI} !\.(.*) [OR] RewriteCond %{REQUEST_URI} \.php.*$ [NC] #If the requested file is not seo-urls-mapper.php (avoid .htaccess loop) RewriteCond %{REQUEST_FILENAME} (?<!seo-urls-mapper)\.php.*$ #If the requested URI is not in an excluded location RewriteCond %{REQUEST_URI} !^/(excluded1|excluded2)/ #Then serve the URI via the mapper RewriteRule .* /seo-urls/seo-urls-mapper.php?uri=%{REQUEST_URI} [L,QSA] Hopefully someone will be able to clarify this issue... I guess I don't fully understand the use of [OR]. Thanks!

• htaccess rewriting all subdomains to subdirectories

  - by indorock

  I'm trying to build a catch-all for any subdomains (not captured by previous rewrite rules) for a certain domain, and serve a website from a subdirectory that resides in the same folder as the .htaccess file. I already have my vhosts.conf to send all unmapped requests to a "playground" folder, where I want to easily create new subdomains by simply adding a subfolder. So, my structure looks like this: /var/www/playground |-> /foo |-> /bar The .htacces living inside the /playground folder and /foo and /bar being seperate websites. I want http://foo.domain.com to point to /foo and http://bar.domain.com to /bar. Here is my .htaccess file: RewriteEngine On RewriteCond %{HTTP_HOST} ^([^.]+).domain.com$ [NC] RewriteCond %{REQUEST_URI} !^/%1/(.*) RewriteRule ^(.*) /%1/$1 [L] This is supposed to capture the subdomain, add it as a subfolder in RewriteRule, then append after the slash and path information. The second RewriteCond is there to prevent an infinite loop. My idea was that %1 in the second RewriteCond would be able to capture the capture group in the first RewriteCond. But so far I haven't had any success, it's always ending up in a redirect loop. If I would replace %1 in the second RewriteCond with hardcoded 'foo' or 'bar', it works, which leads me to believe that you cannot refer to a capture group inside a RewriteCond. Is is true? Or am I missing something?

• Is it safe to format this partition?

  - by xanesis4

  On a ubuntu server I own, I am running out of space. When I ran sudo parted /dev/sda -l to find all available drives, I got this: Model: ATA ST31000528AS (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 256MB 255MB primary ext2 boot 2 257MB 1000GB 1000GB extended 5 257MB 1000GB 1000GB logical lvm Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/server--vg-swap_1: 2135MB Sector size (logical/physical): 512B/512B Partition Table: loop Number Start End Size File system Flags 1 0.00B 2135MB 2135MB linux-swap(v1) Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/server--vg-root: 998GB Sector size (logical/physical): 512B/512B Partition Table: loop Number Start End Size File system Flags 1 0.00B 998GB 998GB ext4 I understand /dev/mapper/server--vg-root is the filesystem, and /dev/sda1 has some stuff related to GRUB. But, what about /dev/sda2 and /dev/sda5? When I tried to mount /dev/sda2, it said that I needed to specify the file system, which according to the table, is nonexistent. So, is it safe to format this with, say ext4 and mount it? Also, when I tried to mount /dev/sd5, it gave me this error: mount: unknown filesystem type 'LVM2_member' I assume it is NOT save to reformat this. If I'm wrong, then that would be great, because I could save some space. Please let me know either way. Thanks in advance!

• Invalid or expired security context token in WCF web service

  - by Damian

  All, I have a WCF web service (let's called service "B") hosted under IIS using a service account (VM, Windows 2003 SP2). The service exposes an endpoint that use WSHttpBinding with the default values except for maxReceivedMessageSize, maxBufferPoolSize, maxBufferSize and some of the time outs that have been increased. The web service has been load tested using Visual Studio Load Test framework with around 800 concurrent users and successfully passed all tests with no exceptions being thrown. The proxy in the unit test has been created from configuration. There is a sharepoint application that use the Office Sharepoint Server Search service to call web services "A" and "B". The application will get data from service "A" to create a request that will be sent to service "B". The response coming from service "B" is indexed for search. The proxy is created programmatically using the ChannelFactory. When service "A" takes less than 10 minutes, the calls to service "B" are successfull. But when service "A" takes more time (~20 minutes) the calls to service "B" throw the following exception: Exception Message: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail Inner Exception Message: The message could not be processed. This is most likely because the action 'namespace/OperationName' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding. The binding settings are the same, the time in both client server and web service server are synchronize with the Windows Time service, same time zone. When i look at the server where web service "B" is hosted i can see the following security errors being logged: Source: Security Category: Logon/Logoff Event ID: 537 User NT AUTHORITY\SYSTEM Logon Failure: Reason: An error occurred during logon Logon Type: 3 Logon Process: Kerberos Authentication Package: Kerberos Status code: 0xC000006D Substatus code: 0xC0000133 After reading some of the blogs online, the Status code means STATUS_LOGON_FAILURE and the substatus code means STATUS_TIME_DIFFERENCE_AT_DC. but i already checked both server and client clocks and they are syncronized. I also noticed that the security token seems to be cached somewhere in the client server because they have another process that calls the web service "B" using the same service account and successfully gets data the first time is called. Then they start the proccess to update the office sharepoint server search service indexes and it fails. Then if they called the first proccess again it will fail too. Has anyone experienced this type of problems or have any ideas? Regards, --Damian

• WPF ListBox not binding to INotifyCollectionChanged or INotifyPropertyChanged Events

  - by Gabe Anzelini

  I have the following test code: private class SomeItem{ public string Title{ get{ return "something"; } } public bool Completed { get { return false; } set { } } } private class SomeCollection : IEnumerable<SomeItem>, INotifyCollectionChanged { private IList<SomeItem> _items = new List<SomeItem>(); public void Add(SomeItem item) { _items.Add(item); CollectionChanged(this, new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset)); } #region IEnumerable<SomeItem> Members public IEnumerator<SomeItem> GetEnumerator() { return _items.GetEnumerator(); } #endregion #region IEnumerable Members System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() { return _items.GetEnumerator(); } #endregion #region INotifyCollectionChanged Members public event NotifyCollectionChangedEventHandler CollectionChanged; #endregion } private SomeCollection collection = new SomeCollection(); private void Expander_Expanded(object sender, RoutedEventArgs e) { var expander = (Expander) sender; var list = expander.DataContext as ITaskList; var listBox = (ListBox)expander.Content; //list.Tasks.CollectionChanged += CollectionChanged; collection.Add(new SomeItem()); collection.Add(new SomeItem()); listBox.ItemsSource = collection; } and the XAML the outer listbox gets populated on load. when the expander gets expanded i then set the itemssource property of the inner listbox (the reason i do this hear instead of using binding is this operation is quite slow and i only want it to take place if the use chooses to view the items). The inner listbox renders fine, but it doesn't actually subscribe to the CollectionChanged event on the collection. I have tried this with ICollection instead of IEnumerable and adding INotifyPropertyChanged as well as replacing INotifyCollectionChanged with INotifyPropertyChanged. The only way I can actually get this to work is to gut my SomeCollection class and inherit from ObservableCollection. My reasoning for trying to role my own INotifyCollectionChanged instead of using ObservableCollection is because I am wrapping a COM collection in the real code. That collection will notify on add/change/remove and I am trying to convert these to INotify events for WPF. Hope this is clear enough (its late).

• C++ template-function -> passing a template-class as template-argument

  - by SeMa

  Hello, i try to make intensive use of templates to wrap a factory class: The wrapping class (i.e. classA) gets the wrapped class (i.e. classB) via an template-argument to provide 'pluggability'. Additionally i have to provide an inner-class (innerA) that inherits from the wrapped inner-class (innerB). The problem is the following error-message of the g++ "gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)": sebastian@tecuhtli:~/Development/cppExercises/functionTemplate$ g++ -o test test.cpp test.cpp: In static member function ‘static classA<A>::innerA<iB>* classA<A>::createInnerAs(iB&) [with iB = int, A = classB]’: test.cpp:39: instantiated from here test.cpp:32: error: dependent-name ‘classA::innerA<>’ is parsed as a non-type, but instantiation yields a type test.cpp:32: note: say ‘typename classA::innerA<>’ if a type is meant As you can see in the definition of method createInnerBs, i intend to pass a non-type argument. So the use of typename is wrong! The code of test.cpp is below: class classB{ public: template < class iB> class innerB{ iB& ib; innerB(iB& b) :ib(b){} }; template<template <class> class classShell, class iB> static classShell<iB>* createInnerBs(iB& b){ // this function creates instances of innerB and its subclasses, // because B holds a certain allocator return new classShell<iB>(b); } }; template<class A> class classA{ // intention of this class is meant to be a pluggable interface // using templates for compile-time checking public: template <class iB> class innerA: A::template innerB<iB>{ innerA(iB& b) :A::template innerB<iB>(b){} }; template<class iB> static inline innerA<iB>* createInnerAs(iB& b){ return A::createInnerBs<classA<A>::template innerA<> >(b); // line 32: error occurs here } }; typedef classA<classB> usable; int main (int argc, char* argv[]){ int a = 5; usable::innerA<int>* myVar = usable::createInnerAs(a); return 0; } Please help me, i have been faced to this problem for several days. Is it just impossible, what i'm trying to do? Or did i forgot something? Thanks, Sebastian

• Wrapping Arbitrary XML within XML

  - by Marc C

  I need to embed arbitrary (syntactically valid) XML documents within a wrapper XML document. The embedded documents are to be regarded as mere text, they do not need to be parseable when parsing the wrapper document. I know about the "CDATA trick", but I can't use that if the inner XML document itself contains a CDATA segment, and I need to be able to embed any valid XML document. Any advice on accomplishing this--or working around the CDATA limitation--would be appreciated.

• Warning: This class was probably produced by a broken compiler.

  - by Michal Dymel

  I have added Jacson libs to my android project and now I am getting such warnings in console: warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.) I've tried to recompile libs, but it didn't help. Warnings are gone when I remove these libs from project. Everything is working fine on the device, but this annoys me ;) Do you know any solution?

• I'm referencing an WiX extension in a WiX library project -- how do I avoid having to reference this

  - by arathorn

  I'm referencing a WiX extension in a WiX library project. This WiX library project is itself referenced by my main WiX MSI project. Why does the main project have to also reference the WiX extension, even though it doesn't directly need it? I'd like to keep my wixlib's as self-contained as possible, so that other projects that use them don't need to know about their inner workings. I'm using latest stable release of WiX (3.0.x).

• How can I set fancyBox's contents dynamically?

  - by alex

  I have tried $('.selector').fancybox({ scrolling : 'no', titleShow : false, type : 'inline', content : '<p>hello</p>' But it did not work I have also tried adding the option onComplete: function() { $('#fancybox-inner').html(contents); } Except then when fancyBox is closed, it will not launch again. How can I dynamically set the contents of fancyBox, and retain all of it's functionality? Thanks

• How do I avoid a repetitive subquery JOIN in SQL?

  - by Karl

  Hi In SQL Server 2008: I have one table, and I want to do something along the following lines: SELECT T1.stuff, T2.morestuff from ( SELECT code, date1, date2 from Table ) as T1 INNER JOIN ( SELECT code, date1, date2 from Table ) as T2 ON T1.code = T2.code and T1.date1 = T2.date2 The two subqueries are exactly identical. Is there any way I can do this without repeating the subquery script? Thanks Karl

• Python performance: iteration and operations on nested lists

  - by J.J.

  Problem Hey folks. I'm looking for some advice on python performance. Some background on my problem: Given: A mesh of nodes of size (x,y) each with a value (0...255) starting at 0 A list of N input coordinates each at a specified location within the range (0...x, 0...y) Increment the value of the node at the input coordinate and the node's neighbors within range Z up to a maximum of 255. Neighbors beyond the mesh edge are ignored. (No wrapping) BASE CASE: A mesh of size 1024x1024 nodes, with 400 input coordinates and a range Z of 75 nodes. Processing should be O(x*y*Z*N). I expect x, y and Z to remain roughly around the values in the base case, but the number of input coordinates N could increase up to 100,000. My goal is to minimize processing time. Current results I have 2 current implementations: f1, f2 Running speed on my 2.26 GHz Intel Core 2 Duo with Python 2.6.1: f1: 2.9s f2: 1.8s f1 is the initial naive implementation: three nested for loops. f2 is replaces the inner for loop with a list comprehension. Code is included below for your perusal. Question How can I further reduce the processing time? I'd prefer sub-1.0s for the test parameters. Please, keep the recommendations to native Python. I know I can move to a third-party package such as numpy, but I'm trying to avoid any third party packages. Also, I've generated random input coordinates, and simplified the definition of the node value updates to keep our discussion simple. The specifics have to change slightly and are outside the scope of my question. thanks much! f1 is the initial naive implementation: three nested for loops. 2.9s def f1(x,y,n,z): rows = [] for i in range(x): rows.append([0 for i in xrange(y)]) for i in range(n): inputX, inputY = (int(x*random.random()), int(y*random.random())) topleft = (inputX - z, inputY - z) for i in xrange(max(0, topleft[0]), min(topleft[0]+(z*2), x)): for j in xrange(max(0, topleft[1]), min(topleft[1]+(z*2), y)): if rows[i][j] <= 255: rows[i][j] += 1 f2 is replaces the inner for loop with a list comprehension. 1.8s def f2(x,y,n,z): rows = [] for i in range(x): rows.append([0 for i in xrange(y)]) for i in range(n): inputX, inputY = (int(x*random.random()), int(y*random.random())) topleft = (inputX - z, inputY - z) for i in xrange(max(0, topleft[0]), min(topleft[0]+(z*2), x)): l = max(0, topleft[1]) r = min(topleft[1]+(z*2), y) rows[i][l:r] = [j+1 for j in rows[i][l:r] if j < 255]

• T-SQL selecting values that match ISNUMERIC and also are within a specified range. (plus Linq-to-sql

  - by Toby

  I am trying to select rows from a table where one of the (NVARCHAR) columns is within a numeric range. SELECT ID, Value FROM Data WHERE ISNUMERIC(Value) = 1 AND CONVERT(FLOAT, Value) < 66.6 Unfortunately as part of the SQL spec the AND clauses don't have to short circuit (and don't on MSSQL Server EE 2008). More info: http://stackoverflow.com/questions/789231/is-the-sql-where-clause-short-circuit-evaluated My next attempt was to try this to see if I could achieve delayed evaluation of the CONVERT SELECT ID, Value FROM Data WHERE (CASE WHEN ISNUMERIC(Value) = 1 THEN CONVERT(FLOAT, Value) < 66.6 ELSE 0 END) but I cannot seem to use a < (or any comparison) with the result of a CONVERT. It fails with the error Incorrect syntax near '<'. I can get away with SELECT ID, CONVERT(FLOAT, Value) AS Value FROM Data WHERE ISNUMERIC(Value) = 1 So the obvious solution is to wrap the whole select statement in another SELECT and WHERE and return the converted values from the inner select and filter in there where of the outer select. Unfortunately this is where my Linq-to-sql problem comes in. I am filtering not only by one range but potentialy by many, or just by the existance of the record (there are some date range selects and comparisons I've left out.) Essentially I would like to be able to generate something like this: SELECT ID, TypeID, Value FROM Data WHERE (TypeID = 4 AND ISNUMERIC(Value) AND CONVERT(Float, Value) < 66.6) OR (TypeID = 8 AND ISNUMERIC(Value) AND CONVERT(Float, Value) > 99) OR (TypeID = 9) (With some other clauses in each of those where options.) This clearly doesn't work if I filter out the non-ISNUMERIC values in an inner select. As I mentioned I am using Linq-to-sql (and PredicateBulider) to build up these queries but unfortunately Datas.Where(x => ISNUMERIC(x.Value) ? Convert.ToDouble(x.Value) < 66.6 : false) Gets converted to this which fails the initial problem. WHERE (ISNUMERIC([t0].[Value]) = 1) AND ((CONVERT(Float,[t0].[Value])) < @p0) My last resort will have to be to outer join against a double select on the same table for each of the comparisons but this isn't really an idea solution. I was wondering if anyone has run into similar issues before?
