  • 12.10 unable to install or even run from Live CD with nVidia GTX 580

    - by user99056
    I've used Ubuntu in the past (set up as web server, etc over in Iraq), so I'm not a 100% Linux Noob, however, I'm running into a brick wall here. I've got a machine I built when I got back to the US earlier this year, running Windows 7 Ultimate on it, and I've now got some free time and would like to transition over to Ubuntu full time. I've searched around in the forums, and there seems to be an issue with the nVidia graphics cards, so I've tried going to the EVGA site to see if I could find a new BIOS update for it and had no luck, so I'm back searching the forums here again and decided to just go ahead and post my question. My apologies if this is covered in another post and I was just unable to find it. I've found a few 'similar' posts, but nothing as bad as my issue. With the history aside, here is the actual detailed issue: I purchased a new SSD (Intel 520 SSD), arrived today, and I disconnect my old Windows 7 SSD. I had pre downloaded the ubuntu-12.10-desktop-amd64 earlier today and burned it to DVD. Upon inserting the Live CD into the computer and booting up, everything was fine up to the 'Run From Live CD' or 'Install Ubuntu Now' buttons. As I was sure I wanted to go ahead and make the switch, I selected the 'Install Now' from the right hand side. CD Spins up, black window pops up, and then the errors started: date/time GPU Lockup date/time Failed to idle channel 1 date/time PFIFO - playlist update failed date/time Failed to idle channel 2 date/time PFIFO - playlist update failed Thinking it might correct itself, I let it run and it would swap over to a GUI Screen that was locked up with major blurring/etc, then back to the command line with the errors. Eventually it said something along the lines of 'unknown status' and switched back to the GUI and froze. So, that's when I tried to see if I could find a BIOS upgrade for the nVidia GTX580 cards, and had no luck. So I thought, why not try to just run it from the Live CD and see if I can at least get a look at it, maybe if I could get it running try to do some sort of install from there and fix the driver issue. I rebooted, brought up the Live CD, and this time chose the left option / run from the CD. It brought me all the way in to the desktop, I saw my drives, the other icons, could move the mouse, etc for about 30 seconds and then it locked up completely. I've tried this a couple of times and get the same results every time. Hardware: Intel i7-3930K CPU @ 3.2GHz (12 CPUs) / MSI MS-7760 Motherboard / 32GB RAM / 2 x EVGA (nVidia) GeForce GTX 580 (4GB Ram each) So the question is: Is there any way to install 12.10 if you can't even get the Live CD to run (for more than 30 seconds)? My current hardware configuration is both of the GTX 580 cards have an SLI jumper on them, and I have 2 monitors on each card. (Ubuntu info obviously only shows on the main monitor from the failed installation and the attempt at running the Live CD). Perhaps opening the machine back up and removing the SLI Jumper and removing the other 3 monitors (so it only would have 1 video card with one monitor on it) would actually allow me to get 12.10 installed, then I could work on an nVidia Video Driver fix for the GTX 580, and then possibly hook up the other video card and monitors? Or is this something that they are currently aware of and may update with a future release in the next few days/weeks? Any thoughts or suggestions would be greatly appreciated, as I can't even try to fix the issue (assuming it is the nVidia drivers) if I can't even get it to install at all.

  • Detect user logout / shutdown in Python / GTK under Linux

    - by Ivo Wetzel
    OK this is presumably a hard one, I've got an pyGTK application that has random crashes due to X Window errors that I can't catch/control. So I created a wrapper that restarts the app as soon as it detects a crash, now comes the problem, when the user logs out or shuts down the system, the app exits with status 1. But on some X errors it does so too. So I tried literally anything to catch the shutdown/logout, with no success, here's what I've tried: import pygtk import gtk import sys class Test(gtk.Window): def delete_event(self, widget, event, data=None): open("delete_event", "wb") def destroy_event(self, widget, data=None): open("destroy_event", "wb") def destroy_event2(self, widget, event, data=None): open("destroy_event2", "wb") def __init__(self): gtk.Window.__init__(self, gtk.WINDOW_TOPLEVEL) self.show() self.connect("delete_event", self.delete_event) self.connect("destroy", self.destroy_event) self.connect("destroy-event", self.destroy_event2) def foo(): open("add_event", "wb") def ex(): open("sys_event", "wb") from signal import * def clean(sig): f = open("sig_event", "wb") f.write(str(sig)) f.close() exit(0) for sig in (SIGABRT, SIGILL, SIGINT, SIGSEGV, SIGTERM): signal(sig, lambda *args: clean(sig)) def at(): open("at_event", "wb") import atexit atexit.register(at) f = Test() sys.exitfunc = ex gtk.quit_add(gtk.main_level(), foo) gtk.main() open("exit_event", "wb") Not one of these succeeds, is there any low level way to detect the system shutdown? Google didn't find anything related to that. I guess there must be a way, am I right? :/

  • new ActiveXObject('Word.Application') creates new winword.exe process when IE security does not allo

    - by Mark Ott
    We are using MS Word as a spell checker for a few fields on a private company web site, and when IE security settings are correct it works well. (Zone for the site set to Trusted, and trusted zone modified to allow control to run without prompting.) The script we are using creates a word object and closes it afterward. While the object exists, a winword.exe process runs, but it is destroyed when the word object is closed. If our site is not set in the trusted zone (Internet zone with default security level) the call that creates the word object fails as expected, but the winword.exe process is still created. I do not have any way to interact with this process in the script, so the process stays around until the user logs off (users have no way to manually destroy the process, and it wouldn't be a good solution even if they did.) The call that attempts to create the object is... try { oWordApplication = new ActiveXObject('Word.Application'); } catch(error) { // irrelevant code removed, described in comments.. // notify user spell check cannot be used // disable spell check option } So every time the page is loaded this code may be run again, creating yet another orphan winword.exe process. oWordApplication is, of course, undefined in the catch block. I would like to be able to detect the browser security settings beforehand, but I have done some searching on this and do not think that it is possible. Management here is happy with it as it is. As long as IE security is set correctly it works, and it works well for our purposes. (We may eventually look at other options for spell check functionality, but this was quick, inexpensive, and does everything we need it to do.) This last problem bugs me and I'd like to do something about it, but I'm out of ideas and I have other things that are more in need of my attention. Before I put it aside, I thought I'd ask for suggestions here...

  • Programming Java 7 in Eclipse

  • Silverlight WCF serialization DataContract(IsReference=true) problem

    - by Ciaran
    Hi, I'm have a Silverlight 3 UI that access WCF services which in turn access respositories that use NHibernate. To overcome some NHibernate lazy loading issues with WCF I'm using my own DataContract surrogate as described here: http://timvasil.com/blog14/post/2008/02/WCF-serialization-with-NHibernate.aspx. In here I'm setting preserveObjectReferences = true My model contains cycles (i.e. Customer with IList[Order]) When I retrieve an object from my service it works fine, however when I try and send that same object back to the wcf service I get the error: System.ServiceModel.CommunicationException was unhandled by user code Message=There was an error while trying to serialize parameter http://tempuri.org/:searchCriteria. The InnerException message was 'Object graph ...' contains cycles and cannot be serialized if references are not tracked. Consider using the DataContractAttribute with the IsReference property set to true.' So cyclical references are now a problem in Silverlight, so I try change my DataContract to be [DataContract(IsReference=true)] but now when I try to retrieve an object from my service I get the following exception: System.ExecutionEngineException was unhandled Message=Exception of type 'System.ExecutionEngineException' was thrown. InnerException: Any ideas?

  • ValueProvider.GetValue Extension Method

    - by griegs
    I have a model like this; public class QuickQuote { [Required] public Enumerations.AUSTRALIA_STATES state { get; set; } [Required] public Enumerations.FAMILY_TYPE familyType { get; set; } As you can see the two proerties are enumerations. Now I want to employ my own model binder for reasons that I won't bother getting into at the moment. So I have; public class QuickQuoteBinder : DefaultModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { quickQuote = new QuickQuote(); try { quickQuote.state = (Enumerations.AUSTRALIA_STATES) Enum.Parse(typeof(Enumerations.AUSTRALIA_STATES), bindingContext.ValueProvider.GetValue(bindingContext.ModelName + ".state").AttemptedValue); } catch { ModelState modelState = new ModelState(); ModelError err = new ModelError("Required"); modelState.Errors.Add(err); bindingContext.ModelState.Add(bindingContext.ModelName + ".state", modelState); } The problem is that for each property, and there are heaps, I need to do the whole try catch block. What I thought I might do is create an extension method which would do the whole block for me and all i'd need to pass in is the model property and the enumeration. So I could do something like; quickQuote.state = bindingContext.ValueProvider.GetModelValue("state", ...) etc. Is this possible?

  • Getting fields_for and accepts_nested_attributes_for to work with a belongs_to relationship

    - by Billy Gray
    I cannot seem to get a nested form to generate in a rails view for a belongs_to relationship using the new accepts_nested_attributes_for facility of Rails 2.3. I did check out many of the resources available and it looks like my code should be working, but fields_for explodes on me, and I suspect that it has something to do with how I have the nested models configured. The error I hit is a common one that can have many causes: '@account[owner]' is not allowed as an instance variable name Here are the two models involved: class Account < ActiveRecord::Base # Relationships belongs_to :owner, :class_name => 'User', :foreign_key => 'owner_id' accepts_nested_attributes_for :owner has_many :users end class User < ActiveRecord::Base belongs_to :account end Perhaps this is where I am doing it 'rong', as an Account can have an 'owner', and may 'users', but a user only has one 'account', based on the user model account_id key. This is the view code in new.html.haml that blows up on me: - form_for :account, :url => account_path do |account| = account.text_field :name - account.fields_for :owner do |owner| = owner.text_field :name And this is the controller code for the new action: class AccountsController < ApplicationController # GET /account/new def new @account = Account.new end end When I try to load /account/new I get the following exception: NameError in Accounts#new Showing app/views/accounts/new.html.haml where line #63 raised: @account[owner] is not allowed as an instance variable name If I try to use the mysterious 'build' method, it just bombs out in the controller, perhaps because build is just for multi-record relationships: class AccountsController < ApplicationController # GET /account/new def new @account = Account.new @account.owner.build end end You have a nil object when you didn't expect it! The error occurred while evaluating nil.build If I try to set this up using @account.owner_attributes = {} in the controller, or @account.owner = User.new, I'm back to the original error, "@account[owner] is not allowed as an instance variable name". Does anybody else have the new accepts_nested_attributes_for method working with a belongs_to relationship? Is there something special or different you have to do? All the official examples and sample code (like the great stuff over at Ryans Scraps) is concerned with multi-record associations.

  • Oracle & Active Directory : A love/hate relationship

    - by Frank
    Hi SO'ers, I'm currently trying to access Active Directory via the dbms_ldap API in Pl/Sql (Oracle). The trouble is that I'm not able to connect with my own username and password or anynoymously. However, in C# I can connect anonymously with this code : DirectoryEntry ldap = new DirectoryEntry("LDAP://Hostname"); DirectorySearcher searcher = new DirectorySearcher(ldap); searcher.Filter = "(SAMAccountName=username)"; SearchResult result = searcher.FindOne(); If I try to connect anonymously in Oracle, I only get the error(ORA-31202 : LDAP client/server error) when I try to search (and the result code for the bind is SUCCESS)... my_session := dbms_ldap.init('HOST','389'); retval := dbms_ldap.simple_bind_s(my_session, '', ''); retval := dbms_ldap.search_s(my_session, ldap_base, dbms_ldap.scope_subtree, 'objectclass=*', my_attrs, 0, my_message); Why is the anonymous connection is C# works but doesn't work in Pl/Sql? Do you have any other idea to connect to Active Directory via Oracle? Help me reunite them together. Thanks. Edit When I bind with anonymous credentials I get : ORA-31202: DBMS_LDAP: LDAP client/server error 00000000: LdapErr: DSID-0C090627, comment: In order to perform this operation a successful bind must be completed on the connection And if I try to connect with my credentials, which are supposed to be valid since I'm connected to the domain with it...

  • Display Simple Web Page In My Application Using Blackberry BrowserField

    - by ankit
    Hello All, What I am trying to do is display a simple web page in my application (no javascript,cookies or any scripting and not trying to detect any events such as mouse click etc.). I am using the code below and right now all I get is empty screen .. I know that the application is accessing the internet (the data transfer arrow flashes in the top right corner) but not sure why its not rendering. The code I am using is : HttpConnectionFactory factory = new HttpConnectionFactory("www.google.ca",HttpConnectionFactory.TRANSPORT_WIFI | HttpConnectionFactory.TRANSPORT_WAP2 | HttpConnectionFactory.TRANSPORT_DIRECT_TCP); while(true) { try { HttpConnection connection = factory.getNextConnection(); try { BrowserContent bc = RenderingSession.getNewInstance().getBrowserContent(connection,null,0); Field f = bc.getDisplayableContent(); add(f); } catch(RenderingException e) { //Log the error or store it for displaying to //the end user if no transports succeed System.out.println("error with rendering page"); } } catch(NoMoreTransportsException e) { //There are no more transports to attempt //Dialog.alert( "Unable to perform request" ); //Note you should never //attempt network activity on the event thread System.out.println("no more transport"); break; } } Some points to note: Im using the http-connection-factory class from www.versatilemonkey.com only becuase they have impelemented the abstract httpConnection class. If someone can also point me on how to implement my own that would be great. I am using '0' for the flags for getBrowserContent function. I looked through the rimn documentation and could not find an explanation for them. Any help would be greatly appreciated. Thanks, ankit

    - by ikurtz
    The following class implements a chatGUI. When it runs okay the screen looks like this: Fine ChatGUI The problem is very often when i enter text of large length ie. 50 - 100 chars the gui goes crazy. the chat history box shrinks as shown in this image. Any ideas regarding what is causing this?

  • Problems with MediaRecorder class setting audio source - setAudioSource() - unsupported parameter

    - by arakn0
    Hello everybody, I'm new in Android development and I have the next question/problem. I'm playing around with the MediaRecorder class to record just audio from the microphone. I'm following the steps indicated in the official site: http://developer.android.com/reference/android/media/MediaRecorder.html So I have a method that initializes and configure the MediaRecorder object in order to start recording. Here you have the code: this.mr = new MediaRecorder(); this.mr.setAudioSource(MediaRecorder.AudioSource.MIC); this.mr.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); this.mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); this.mr.setOutputFile(this.path + this.fileName); try { this.mr.prepare(); } catch (IllegalStateException e) { Log.d("Syso", e.toString()); e.printStackTrace(); } catch (IOException e) { Log.d("Syso", e.toString()); e.printStackTrace(); } When I execute this code in the simulator, thanks to logcat, I can see that the method setAudioSource(MediaRecorder.AudioSource.MIC) gives the next error (with the tag audio_ipunt) when it is called: ERROR/audio_input(34): unsupported parameter: x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value ERROR/audio_input(34): VerifyAndSetParameter failed And then when the method prepare() is called, I get the another error again: ERROR/PVOMXEncNode(34): PVMFOMXEncNode-Audio_AMRNB::DoPrepare(): Got Component OMX.PV.amrencnb handle If I start to record bycalling the method start()... I get lots of messages saying: AudioFlinger(34):RecordThread: buffer overflow Then...after stop and release,.... I can see that a file has been created, but it doesn't seem that it been well recorderd. Anway, if i try this in a real device I can record with no problems, but I CAN'T play what I just recorded. I gues that the key is in these errors that I've mentioned before. How can I fix them? Any suggestion or help?? Thanks in advanced!!

  • generic DAO in java

    - by akshay
    I am trying to develop generic DAO in java.I have tried the following.Is this a good way to implement generic dao?I dont want to use hibernate.I am trying to make it as generic as possible so that i dont have to repeate the same code again and again. public abstract class AbstractDAO<T> { protected ResultSet findbyId(String tablename, Integer id){ ResultSet rs= null; try { // the following lins in not working; pStmt = cn.prepareStatement("SELECT * FROM "+ tablename+ "WHERE id = ?"); pStmt.setInt(1, id); rs = pStmt.executeQuery(); } catch (SQLException ex) { System.out.println("ERROR in findbyid " +ex.getMessage() +ex.getCause()); ex.printStackTrace(); }finally{ return rs; } } } Now i have public class UserDAO extends AbstractDAO<User>{ public List<User> findbyid(int id){ Resultset rs =findbyid("USERS",id) //USERS is tablename in db List<Users> users = convertToList(rs); return users; } private List<User> convertToList(ResultSet rs) { List<User> userList= new ArrayList(); User user= new User();; try { while (rs.next()) { user.setId(rs.getInt("id")); user.setUsername(rs.getString("username")); user.setFname(rs.getString("fname")); user.setLname(rs.getString("lname")); user.setUsertype(rs.getInt("usertype")); user.setPasswd(rs.getString("passwd")); userList.add(user); } } catch (SQLException ex) { Logger.getLogger(UserDAO.class.getName()).log(Level.SEVERE, null, ex); } return userList; } }

  • How do you construct an array suitable for numpy sorting?

    - by Alex
    I need to sort two arrays simultaneously, or rather I need to sort one of the arrays and bring the corresponding element of its associated array with it as I sort. That is if the array is [(5, 33), (4, 44), (3, 55)] and I sort by the first axis (labeled below dtype='alpha') then I want: [(3.0, 55.0) (4.0, 44.0) (5.0, 33.0)]. These are really big data sets and I need to sort first ( for nlog(n) speed ) before I do some other operations. I don't know how to merge my two separate arrays though in the proper manner to get the sort algorithm working. I think my problem is rather simple. I tried three different methods: import numpy x=numpy.asarray([5,4,3]) y=numpy.asarray([33,44,55]) dtype=[('alpha',float), ('beta',float)] values=numpy.array([(x),(y)]) values=numpy.rollaxis(values,1) #values = numpy.array(values, dtype=dtype) #a=numpy.array(values,dtype=dtype) #q=numpy.sort(a,order='alpha') print "Try 1:\n", values values=numpy.empty((len(x),2)) for n in range (len(x)): values[n][0]=y[n] values[n][1]=x[n] print "Try 2:\n", values #values = numpy.array(values, dtype=dtype) #a=numpy.array(values,dtype=dtype) #q=numpy.sort(a,order='alpha') ### values = [(x[0], y[0]), (x[1],y[1]) , (x[2],y[2])] print "Try 3:\n", values values = numpy.array(values, dtype=dtype) a=numpy.array(values,dtype=dtype) q=numpy.sort(a,order='alpha') print "Result:\n",q I commented out the first and second trys because they create errors, I knew the third one would work because that was mirroring what I saw when I was RTFM. Given the arrays x and y (which are very large, just examples shown) how do I construct the array (called values) that can be called by numpy.sort properly? *** Zip works great, thanks. Bonus question: How can I later unzip the sorted data into two arrays again?

  • Javascript html5 database transaction problem in loops

    - by Marek
    I'm hittig my head on this and i will be glad for any help. I need to store in a database a context (a list of string ids) for another page. I open a page with a list of artworks and this page save into the database those artowrks ids. When i click on an artwork i open its webpage but i can access the database to know the context and refer to the next and prev artwork. This is my code to retrieve the contex: updateContext = function () { alert("updating context"); try { mydb.transaction( function(transaction) { transaction.executeSql("select artworks.number from artworks, collections where collections.id = artworks.section_id and collections.short_name in ('cro', 'cra', 'crp', 'crm');", [], contextDataHandler, errorHandler); }); } catch(e) { alert(e.message); } } the contextDatahandler function then iterates through the results and fill again the current_context table: contextDataHandler = function(transaction, results) { try { mydb.transaction( function(transaction) { transaction.executeSql("drop table current_context;", [], nullDataHandler, errorHandler); transaction.executeSql("create table current_context(id String);", [], nullDataHandler, errorHandler); } ) } catch(e) { alert(e.message); } var s = ""; for (var i=0; i < results.rows.length; i++) { var item = results.rows.item(0); s += item['number'] + " "; mydb.transaction( function(tx) { tx.executeSql("insert into current_context(id) values (?);", [item['number']]); } ) } alert(s); } the result is, i get the current_context table deleted, recreated, and filled, but all the rows are filled with the LAST artwork id. the query to retrieve the artworks ids works, so i think it's a transaction problem, but i cant figure out where. thanks for any help

  • In Java Concurrency In Practice by Brian Goetz, why is the Memoizer class not annotated with @ThreadSafe?

    - by dig_dug
    Java Concurrency In Practice by Brian Goetz provides an example of a efficient scalable cache for concurrent use. The final version of the example showing the implementation for class Memoizer (pg 108) shows such a cache. I am wondering why the class is not annotated with @ThreadSafe? The client, class Factorizer, of the cache is properly annotated with @ThreadSafe. The appendix states that if a class is not annotated with either @ThreadSafe or @Immutable that it should be assumed that it isn't thread safe. Memoizer seems thread-safe though. Here is the code for Memoizer: public class Memoizer<A, V> implements Computable<A, V> { private final ConcurrentMap<A, Future<V>> cache = new ConcurrentHashMap<A, Future<V>>(); private final Computable<A, V> c; public Memoizer(Computable<A, V> c) { this.c = c; } public V compute(final A arg) throws InterruptedException { while (true) { Future<V> f = cache.get(arg); if (f == null) { Callable<V> eval = new Callable<V>() { public V call() throws InterruptedException { return c.compute(arg); } }; FutureTask<V> ft = new FutureTask<V>(eval); f = cache.putIfAbsent(arg, ft); if (f == null) { f = ft; ft.run(); } } try { return f.get(); } catch (CancellationException e) { cache.remove(arg, f); } catch (ExecutionException e) { throw launderThrowable(e.getCause()); } } } }
