  • MySQL can't access root account or reset with mysqladmin

    - by glumptious
    So if I type mysql -u root I'm supposedly logged in, however upon trying to create or access a database I get this lovely error: ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'test1'. I haven't the foggiest idea why after logging in as root it's trying access DB's as ''@'localhost' and it's driving me a bit crazy right now. Possibly related, when I try to set the root password I get the error mysqladmin: Can't turn off logging; error: 'Access denied; you need (at least one of) the SUPER privilege(s) for this operation'. I've tried removing mysql-server via running apt-get purge mysql-server and then reinstalling with no luck. This is running Ubuntu Server 12.10 64-bit and mysql is indeed running. --Edit-- I wonder if perhaps there is no root user. So I try to start MySQL with --skip-grant-tables and the create the root user but then I'm given this: ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement. Fun fun fun fun fun.

  • PHP Hashtable array optimisation.

    - by hiprakhar
    I made a PHP app which was taking about ~0.0070sec for execution. Now, I added a hashtable array with about 2000 values. Suddenly the time for execution has gone up to ~0.0700 secs. Almost 10 times the previous value. I tried commenting out the part where I was searching inside the hashtable array (but array was still left defined). Still, the execution time remains about ~0.0500secs. Array is something like: $subjectinfo = array( 'TPT753' => 'Industrial Training', 'TPT801' => 'High Polymeric Engineering', 'TPT802' => 'Corrosion Engineering', 'TPT803' => 'Decorative ,Industrial And High Performance Coatings', 'TPT851' => 'Project'); Is there any way to optimize this part? I cannot use Database as I am running this app on Google app engine which is still not supporting JDO database for php. Some more code from the app: function getsubjectinfo($name) { $subjectinfo = array( 'TPT753' => 'Industrial Training', 'TPT801' => 'High Polymeric Engineering', 'TPT802' => 'Corrosion Engineering', 'TPT803' => 'Decorative ,Industrial And High Performance Coatings', 'TPT851' => 'Project'); $name = str_replace("-", "", $name); $name = str_replace(" ", "", $name); if (isset($subjectinfo["$name"])) return "(".$subjectinfo["$name"].")"; else return ""; } Then I am using the following statement 2-3 times in the app: echo $key." ".$this->getsubjectinfo($key)

  • puzzled with java if else performance

    - by user1906966
    I am doing an investigation on a method's performance and finally identified the overhead was caused by the "else" portion of the if else statement. I have written a small program to illustrate the performance difference even when the else portion of the code never gets executed: public class TestIfPerf { public static void main( String[] args ) { boolean condition = true; long time = 0L; int value = 0; // warm up test for( int count=0; count<10000000; count++ ) { if ( condition ) { value = 1 + 2; } else { value = 1 + 3; } } // benchmark if condition only time = System.nanoTime(); for( int count=0; count<10000000; count++ ) { if ( condition ) { value = 1 + 2; } } time = System.nanoTime() - time; System.out.println( "1) performance " + time ); time = System.nanoTime(); // benchmark if else condition for( int count=0; count<10000000; count++ ) { if ( condition ) { value = 1 + 2; } else { value = 1 + 3; } } time = System.nanoTime() - time; System.out.println( "2) performance " + time ); } } and run the test program with java -classpath . -Dmx=800m -Dms=800m TestIfPerf. I performed this on both Mac and Linux Java with 1.6 latest build. Consistently the first benchmark, without the else is much faster than the second benchmark with the else section even though the code is structured such that the else portion is never executed because of the condition. I understand that to some, the difference might not be significant but the relative performance difference is large. I wonder if anyone has any insight to this (or maybe there is something I did incorrectly). Linux benchmark (in nano) performance 1215488 performance 2629531 Mac benchmark (in nano) performance 1667000 performance 4208000

  • Rolling Back a Transaction with MySQL Connector in VB.net

    - by Jonathan
    Hey all- I have one multi-row INSERT statement (300 or so sets of values) that I would like to commit to the MySQL database in an all-or-nothing fashion. insert into table VALUES (1, 2, 3), (4, 5, 6), (7, 8, 9); In some cases, a set of values in the command will not meet the criteria of the table (duplicate key, for example). When that happens I do not want any of the previous sets added to the database. I've implemented this with the following code, however, my rollback command doesn't appear to be making a difference. I've used this documentation: http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqltransaction.html Dim transaction As MySqlTransaction = sqlConnection.BeginTransaction() sqlCommand = New MySqlCommand(insertStr, sqlConnection, transaction) Try sqlCommand.ExecuteNonQuery() Catch ex As Exception writeToLog("EXCEPTION: " & ex.Message & vbNewLine) writeToLog("Could not execute " & sqlCmd & vbNewLine) Try transaction.Rollback() writeToLog("All statements were rolled back." & vbNewLine) Return False Catch rollbackEx As Exception writeToLog("EXCEPTION: " & rollbackEx.Message & vbNewLine) writeToLog("All statements were not rolled back." & vbNewLine) Return False End Try End Try transaction.commit() I get the DUPLICATE KEY exception thrown, no Rollback Exception thrown, and every set of values up to duplicate key committed to the database. What am I doing wrong? Thanks- Jonathan

  • Templates, and C++ operator for logic: B contained by set A

    - by James Morris
    In C++, I'm looking to implement an operator for selecting items in a list (of type B) based upon B being contained entirely within A. In the book "the logical design of digital computers" by Montgomery Phister jr (published 1958), p54, it says: F11 = A + ~B has two interesting and useful associations, neither of them having much to do with computer design. The first is the logical notation of implication... The second is notation of inclusion... This may be expressed by a familiar looking relation, B < A; or by the statement "B is included in A"; or by the boolean equation F11= A + ~B = 1. My initial implementation was in C. Callbacks were given to the list to use for such operations. An example being a list of ints, and a struct containting two ints, min and max, for selection purposes. There, selection would be based upon B = A-min && B <= A-max. Using C++ and templates, how would you approach this after having implemented a generic list in C using void pointers and callbacks? Is using < as an over-ridden operator for such purposes... <ugh> evil? </ugh> (or by using a class B for the selection criteria, implementing the comparison by overloading ?)

  • Thinking Sphinx with a date range

    - by Leddo
    Hi, I am implementing a full text search API for my rails apps, and so far have been having great success with Thinking Sphinx. I now want to implement a date range search, and keep getting the "bad value for range" error. Here is a snippet of the controller code, and i'm a bit stuck on what to do next. @search_options = { :page => params[:page], :per_page => params[:per_page]||50 } unless params[:since].blank? # make sure date is in specified format - YYYY-MM-DD d = nil begin d = DateTime.strptime(params[:since], '%Y-%m-%d') rescue raise ArgumentError, "Value for since parameter is not a valid date - please use format YYYY-MM-DD" end @search_options.merge!(:with => {:post_date => d..Time.now.utc}) end logger.info @search_options @posts = Post.search(params[:q], @search_options) When I have a look at the log, I am seeing this bit which seems to imply the date hasn't been converted into the same time format as the Time.now.utc. withpost_date2010-05-25T00:00:00+00:00..Tue Jun 01 17:45:13 UTC 2010 Any ideas? Basically I am trying to have the API request pass in a "since" date to see all posts after a certain date. I am specifying that the date should be in the YYYY-MM-DD format. Thanks for your help. Chris EDIT: I just changed the date parameters merge statement to this @search_options.merge!(:with = {:post_date = d.to_date..DateTime.now}) and now I get this error undefined method `to_i' for Tue, 25 May 2010:Date So obviously there is something still not setup right...

  • How to detect when video is buffering?

    - by Leon
    Hi guys, my question today deals with Flash AS3 video buffering. (Streaming or Progressive) I want to be able to detect when the video is being buffered, so I can display some sort of animation letting the user know to wait just a little longer. Currently my video will start up, hold on frame 1 for 3-4 secs then play. Kinda giving the impression that the video is paused or broken :( Update Thanks to iandisme I believe I'm faced in the right direction now. NetStatusEvent from livedocs. It seems to me that the key status to be working in is "NetStream.Buffer.Empty" so I added some code in there to see if this would trigger my animation or a trace statement. No luck yet, however when the Buffer is full it will trigger my code :/ Maybe my video is always somewhere between Buffer.Empty and Buffer.Full that's why it won't trigger any code when I test case for Buffer.Empty? Current Code public function netStatusHandler(event:NetStatusEvent):void { // handles net status events switch (event.info.code) { case "NetStream.Buffer.Empty": trace("¤¤¤ Buffering!"); //<- never traces addChild(bufferLoop); //<- doesn't execute break; case "NetStream.Buffer.Full": trace("¤¤¤ FULL!"); //<- trace works here removeChild(bufferLoop); //<- so does any other code break; case "NetStream.Buffer.Flush": trace("¤¤¤ FLUSH!"); //Not sure if this is important break } }

  • Multiple, Simultaneous Factories and Protocols in Twisted: Same Service, Different Ports

    - by RichardCroasher
    Greetings, Forum. I'm working on a program in Python that uses Twisted to manage networking. The basis of this program is a TCP service that is to listen for connections on multiple ports. However, instead of using one Twisted factory to handle a protocol object for each port, I am trying to use a separate factory for each port. The reason for this is to force a separation among the groups of clients connecting to the different ports. Unfortunately, it appears that this architecture isn't quite working: clients that connect to one port appear to be available among all the factories (e.g., the protocol class used by each factory includes a 'self.factory.clients.append (self)' statement...instead of adding a given client to just the factory for a particular port, the client is added to all factories), and whenever I shutdown service on one port the listeners on all ports also stop. I've been working with Twisted for a short while, and fear I simply don't fully understand how its factory classes are managed. My question is: is it simply not possible to have multiple, simultaneous instances of the same factory and same protocol in use across different ports (without these instances stepping on each other's toes)?

  • Inserting null fields with dbi:Pg

    - by User1
    I have a Perl script inserting data into Postgres according to a pipe delimited text file. Sometimes, a field is null (as expected). However, Perl makes this field into an empty string and the Postgres insert statement fails. Here's a snippet of code: use DBI; #Connect to the database. $dbh=DBI-connect('dbi:Pg:dbname=mydb','mydb','mydb',{AutoCommit=1,RaiseError=1,PrintError=1}); #Prepare an insert. $sth=$dbh-prepare("INSERT INTO mytable (field0,field1) SELECT ?,?"); while (<){ #Remove the whitespace chomp; #Parse the fields. @field=split(/\|/,$_); print "$_\n"; #Do the insert. $sth-execute($field[0],$field[1]); } And if the input is: a|1 b| c|3 EDIT: Use this input instead. a|1|x b||x c|3|x It will fail at b|. DBD::Pg::st execute failed: ERROR: invalid input syntax for integer: "" I just want it to insert a null on field1 instead. Any ideas? EDIT: I simplified the input at the last minute. The old input actually made it work for some reason. So now I changed the input to something that will make the program fail. Also note that field1 is a nullable integer datatype.

  • Key strokes in wpf window hosted in MFC ActiveX running in Internet Explorer

    - by user310046
    We have an MFC ActiveX control created in Visual Studio 2008 with CLR support which creates a WPF grid and shows a WPF window within that grid. This ActiveX is hosted within Internet Explorer and it shows up and works nicely except that the tab key, backspace, function keys etc. does not work since they are handeled by IE instead of the WPF window. Regular characters works nicely. This is a known feature and previously when we used to have MFC based dialogs within this ActiveX we used this: http://support.microsoft.com/kb/187988. By just using this code directly the AfxGetApp()->PreTranslateMessage((LPMSG)lParam) statement will return FALSE, so I'm not able to get the key stroke to be handled by the WPF window. I beleive I need to ask the WPF application this instead of the CWinApp, but I'm not sure how and if this can be done. Does anyone have enough understanding of what's going on here to get this to work? Using XBAP instead of ActiveX is not an option as this is run in an intranet application which needs more access than the sandbox can give us. I hope this is enough information. With best regards Svein Dybvik

  • nested include in php

    - by aeonsleo
    The directory structure: C:/wamp/www/application/model/data_access/data_object.php C:/wamp/www/application/model/users/user.class.php C:/wamp/www/application/controller/projects.php C:/wamp/www/application/controller/links/links.php I have 2 php files data_object.php and user.class.php Now user.class.php has an include statement for data_object.php wchih is relative to user.class.php.These two files are under different directory hierarchy. Now I have to include this user.class.php in various files (like projects.php, links.php-which themselves are under different hierarchy) whenever i want to create a User() object. The problem is the relative path for file inclusion of data_object.php does work for say projects.php but if i open links.php the error message says it could not open file data_object.php in user.class.php. What i think is for relative inclusion of data_object.php it is considering the path of the file in which user.class.php is included. I am facing such problems in more than one scenarios I have to keep my directory structure the way it is but have to find a way to work with nested includes. I used Document root of session it give root path as C:/wamp/www/ i appended the path for data_object.php include but this is not working. (note: the forward slash is present after www) I am currently running on wamp server's localhost but after completion i have to host the solution on a domain. Pls help

  • What's the compelling reason to upgrade to Visual Studio 2010 from VS2008?

    - by Cheeso
    Are there new features in Visual Studio 2010 that are must-haves? If so, which ones? For me, the big draws for VS2008 as compared to VS2005 were LINQ, .NET Framework multitargeting, WCF (REST + Syndication), and general devenv.exe reliability. Granted, some of these features are framework things, and not tool things. For the purposes of this discussion, I'm willing to combine them into one bucket. What is the list of must-have features for VS2010 versus VS2008? Are there any? I am particularly interested in C#. Update: I know how to google, so I can get the official list from Microsoft. I guess what I really wanted was, the assessment from people using it, as to which things are really notable. Microsoft went on for 3 pages about 2008/3.5 features, and many people sort of boiled it down to LINQ, and a few other things. What is that short list for VS2010? Summary so far, what people think is cool or compelling: Visual Studio engine multi-monitor support new extensibility model based on WPF, prettier and more usable new TFS stuff, incl automated test tools parallel debugging .NET Framework parallel extensions for .NET C# 4.0 generic variance optional and named params easier interop with non-managed environments, like COM or Javascript VB 10.0 collection and array literals / initializers automatic properties anonymous methods / statement lambdas I read up on these at Zander's blog. He described these and other features. Nobody on this list said anything about: Visual Studio engine F# support Javascript code-completion JQuery is now included UML better Sharepoint capabilities C++ moves to msbuild project files

  • How does the last integer promotion rule ever get applied in C?

    - by SiegeX
    6.3.1.8p1: Otherwise, the integer promotions are performed on both operands. Then the following rules are applied to the promoted operands: If both operands have the same type, then no further conversion is needed. Otherwise, if both operands have signed integer types or both have unsigned integer types, the operand with the type of lesser integer conversion rank is converted to the type of the operand with greater rank. Otherwise, if the operand that has unsigned integer type has rank greater or equal to the rank of the type of the other operand, then the operand with signed integer type is converted to the type of the operand with unsigned integer type. Otherwise, if the type of the operand with signed integer type can represent all of the values of the type of the operand with unsigned integer type, then the operand with unsigned integer type is converted to the type of the operand with signed integer type. Otherwise, both operands are converted to the unsigned integer type corresponding to the type of the operand with signed integer type. For the bolded rule to be applied it would seem to imply you need to have have an unsigned interger type who's rank is less than the signed integer type and the signed integer type cannot hold all the values of the unsigned integer type. Is there a real world example of such a case or is this statement serving as a catch-all to cover all possible permutations?

  • Windows Messages Bizarreness

  • Generic object to object mapping with parametrized constructor

    - by Rody van Sambeek
    I have a data access layer which returns an IDataRecord. I have a WCF service that serves DataContracts (dto's). These DataContracts are initiated by a parametrized constructor containing the IDataRecord as follows: [DataContract] public class DataContractItem { [DataMember] public int ID; [DataMember] public string Title; public DataContractItem(IDataRecord record) { this.ID = Convert.ToInt32(record["ID"]); this.Title = record["title"].ToString(); } } Unfortanately I can't change the DAL, so I'm obliged to work with the IDataRecord as input. But in generat this works very well. The mappings are pretty simple most of the time, sometimes they are a bit more complex, but no rocket science. However, now I'd like to be able to use generics to instantiate the different DataContracts to simplify the WCF service methods. I want to be able to do something like: public T DoSomething<T>(IDataRecord record) { ... return new T(record); } So I'd tried to following solutions: Use a generic typed interface with a constructor. doesn't work: ofcourse we can't define a constructor in an interface Use a static method to instantiate the DataContract and create a typed interface containing this static method. doesn't work: ofcourse we can't define a static method in an interface Use a generic typed interface containing the new() constraint doesn't work: new() constraint cannot contain a parameter (the IDataRecord) Using a factory object to perform the mapping based on the DataContract Type. does work, but: not very clean, because I now have a switch statement with all mappings in one file. I can't find a real clean solution for this. Can somebody shed a light on this for me? The project is too small for any complex mapping techniques and too large for a "switch-based" factory implementation.

  • NHibernate Oracle stored procedure problem

    - by Mr. Flint
    ------Using VS2008, ASP.Net with C#, Oracle, NHibernate---- I have tested my stored procedure. It's working but not with NHibernate. Here are the codes: Procedure : create or replace procedure ThanaDelete (id number) as begin delete from thana_tbl where thana_code = id; end Mapping File: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DataTransfer" namespace="DataTransfer"> <class name="DataTransfer.Models.Thana, DataTransfer" table="THANA_TBL"> <id name="THANA_CODE" column="THANA_CODE" type="Int32" unsaved-value="0"> <generator class="native"> <param name="sequence"> SEQ_TEST </param> </generator> </id> <property name="THANA_NAME" column="THANA_NAME" type="string" not-null="false"/> <property name="DISTRICT_CODE" column="DISTRICT_CODE" type="Int32" not-null="false"/> <property name="USER_ID" column="USER_ID" type="string" not-null="false"/> <property name="TRANSACTION_DATE" column="TRANSACTION_DATE" type="Date" not-null="false"/> <property name="TRANSACTION_TIME" column="TRANSACTION_TIME" type="string" not-null="false"/> <sql-delete>exec THANADELETE ? </sql-delete> </class> </hibernate-mapping> error: Message: could not delete: [DataTransfer.Models.Thana#10][SQL: exec THANADELETE ?] Source: NHibernate Inner Exception System.Data.OracleClient.OracleException Message: ORA-00900: invalid SQL statement

  • TSQL to insert an ascending value

    - by David Neale
    I am running some SQL that identifies records which need to be marked for deletion and to insert a value into those records. This value must be changed to render the record useless and each record must be changed to a unique value because of a database constraint. UPDATE Users SET Username = 'Deleted' + (ISNULL( Cast(SELECT RIGHT(MAX(Username),1) FROM Users WHERE Username LIKE 'Deleted%') AS INT) ,0) + 1 FROM Users a LEFT OUTER JOIN #ADUSERS b ON a.Username = 'AVSOMPOL\' + b.sAMAccountName WHERE (b.sAMAccountName is NULL AND a.Username LIKE 'AVSOMPOL%') OR b.userAccountControl = 514 This is the important bit: SET Username = 'Deleted' + (ISNULL( Cast(SELECT RIGHT(MAX(Username),1) FROM Users WHERE Username LIKE 'Deleted%') AS INT) ,0) + 1 What I've tried to do is have deleted records have their Username field set to 'Deletedxxx'. The ISNULL is needed because there may be no records matching the SELECT RIGHT(MAX(Username),1) FROM Users WHERE Username LIKE 'Deleted%' statement and this will return NULL. I get a syntax error when trying to parse this (Msg 156, Level 15, State 1, Line 2 Incorrect syntax near the keyword 'SELECT'. Msg 102, Level 15, State 1, Line 2 Incorrect syntax near ')'. I'm sure there must be a better way to go about this, any ideas?

  • How can I programmatically add more than just one view object to my view controller?

    - by BeachRunnerJoe
    I'm diving into iPhone OS development and I'm trying to understand how I can add multiple view objects to the "Left/Root" view of my SplitView iPad app. I've figured out how to programmatically add a TableView to that view based on the example code I found in Apple's online documentation... RootViewController.h @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate, UITableViewDelegate, UITableViewDataSource> { DetailViewController *detailViewController; UITableView *tableView; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } RootViewController.m - (void)loadView { UITableView *newTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; newTableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; newTableView.delegate = self; newTableView.dataSource = self; [newTableView reloadData]; self.view = newTableView; [newTableView release]; } but there are a few things I don't understand about it and I was hoping you veterans could help clear up some confusion. In the statement self.view = newTableView, I assume I'm setting the entire view to a single UITableView. If that's the case, then how can I add additional view objects to that view alongside the table view? For example, if I wanted to have a DatePicker view object and the TableView object instead of just the TableView object, then how would I programmatically add that? Referencing the code above, how can I resize the table view to make room for the DatePicker view object that I'd like to add? Thanks so much in advance for your help! I'm going to continue researching these questions right now.

  • Why do I get CA1806 when I catch exception in C++/CLI?

    - by brickner
    I've recently upgraded my project from Visual Studio 2008 to Visual Studio 2010. By enabling Code Analysis and compiling in Release, I'm getting warning CA1806: Do not ignore method results. I've managed to reduce the code that produces the warning to this code: .h file: public ref class Foo { public: void Bar(); }; .cpp file: void Foo::Bar() { try { } catch (const std::exception&) // here I get the warning { } } the warning: CA1806 : Microsoft.Usage : 'Foo::Bar(void)' calls 'Global::__CxxRegisterExceptionObject(void*, void*)' but does not use the HRESULT or error code that the method returns. This could lead to unexpected behavior in error conditions or low-resource situations. Use the result in a conditional statement, assign the result to a variable, or pass it as an argument to another method. If I try to use the exception value or do catch(...) the warning still appears. If I catch managed exceptions instead or compile in Debug I don't get the warning. Why do I get this warning? UPDATE I've decided to open a bug report on Microsoft Connect.

  • ASP.NET MVC 2 VB, Not recognising my import.

    - by SLC
    I had a problem with a project I converted from C# to VB, in that the VB version it cannot seem to find an object even though I declared it with an Import statement at the top. I created a new, default MVC 2 VB project, and the same problem occurs there. I create a new MVC 2 application, I then add a reference to System.Data.Services.Client, and in my Index.aspx, in the Content area, I type <% Dim x As DataServiceQueryContinuation %> which is what I want to use. It gives me a blue squiggly line and says Type 'DataServiceQueryContinuation' is not defined. At the top of the page, I add this: <%@ Import Namespace="System.Data.Services.Client" %> The error persists. My original C# version has no such error. I also get this warning: Warning 2 Namespace or type specified in the Imports 'System.Data.Services.Client' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. e:\ASPNETDEBUG\MvcApplication1\MvcApplication1\Views\Home\Index.aspx 10 9 MvcApplication1 Examining the DLL using the tool provided shows that it does have a public member. Also when typing the above, System.Data. provides intellisense but there is no 'Services'. Any ideas?

  • Cache consistency & spawning a thread

    - by Dave Keck
    Background I've been reading through various books and articles to learn about processor caches, cache consistency, and memory barriers in the context of concurrent execution. So far though, I have been unable to determine whether a common coding practice of mine is safe in the strictest sense. Assumptions The following pseudo-code is executed on a two-processor machine: int sharedVar = 0; myThread() { print(sharedVar); } main() { sharedVar = 1; spawnThread(myThread); sleep(-1); } main() executes on processor 1 (P1), while myThread() executes on P2. Initially, sharedVar exists in the caches of both P1 and P2 with the initial value of 0 (due to some "warm-up code" that isn't shown above.) Question Strictly speaking – preferably without assuming any particular CPU – is myThread() guaranteed to print 1? With my newfound knowledge of processor caches, it seems entirely possible that at the time of the print() statement, P2 may not have received the invalidation request for sharedVar caused by P1's assignment in main(). Therefore, it seems possible that myThread() could print 0. References These are the related articles and books I've been reading. (It wouldn't allow me to format these as links because I'm a new user - sorry.)
