• Errors when trying to compile the driver for the rtl8192su wireless adapter

  - by Tom Brito

  I have a wireless to usb adapter, and I'm having some trouble to install the drivers on Ubuntu. First of all, the readme says to use the make command, and I already got errors: $ make make[1]: Entering directory `/usr/src/linux-headers-2.6.35-22-generic' CC [M] /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c: In function ‘rtl8192_usb_probe’: /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12325: error: ‘struct net_device’ has no member named ‘open’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12326: error: ‘struct net_device’ has no member named ‘stop’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12327: error: ‘struct net_device’ has no member named ‘tx_timeout’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12328: error: ‘struct net_device’ has no member named ‘do_ioctl’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12329: error: ‘struct net_device’ has no member named ‘set_multicast_list’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12330: error: ‘struct net_device’ has no member named ‘set_mac_address’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12331: error: ‘struct net_device’ has no member named ‘get_stats’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12332: error: ‘struct net_device’ has no member named ‘hard_start_xmit’ make[2]: *** [/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o] Error 1 make[1]: *** [_module_/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-22-generic' make: *** [all] Error 2 /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/ is the path where I copied the drivers on my computer.

• Need help partitioning when reinstalling Ubuntu 14.04

  - by Chris M.

  I upgraded to 14.04 about a month ago on my HP Mini netbook (about 16 GB hard disk). A few days ago the system crashed (I don't know why but I was using internet at the time). When I restarted the computer, Ubuntu would not load. Instead, I got a message from the BIOS saying Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key I took this to mean that I needed to reinstall 14.04. When I try to reinstall Ubuntu from the USB stick, I choose "Erase disk and install Ubuntu" but then I get a message: Some of the partitions you created are too small. Please make the following partitions at least this large: / 3.3 GB If you do not go back to the partitioner and increase the size of these partitions, the installation may fail. At first I hit Continue to see if it would install anyway, and it gave the message: The attempt to mount a file system with type ext4 in SCSI1 (0,0,0), partition # 1 (sda) at / failed. You may resume partitioning from the partitioning menu. The second time I hit Go Back, and it took me to the following partitioning table: Device Type Mount Point Format Size Used System /dev/sda /dev/sda1 ext4 (checked) 3228 MB Unknown /dev/sda5 swap (not checked) 1063 MB Unknown + - Change New Partition Table... Revert Device for boot loader installation: /dev/sda ATA JM Loader 001 (4.3 GB) At this point I'm not sure what to do. I've never partitioned my hard drive before and I don't want to screw things up. (I'm not particularly tech savvy.) Can you instruct me what I should do. (P.S. I'm afraid the table might not appear as I typed it in.)

• How to handle multi-processing of libraries which already spawn sub-processes?

  - by exhuma

  I am having some trouble coming up with a good solution to limit sub-processes in a script which uses a multi-processed library and the script itself is also multi-processed. Both, the library and script are modifiable by us. I believe the question is more about design than actual code, but for what it's worth, it's written in Python. The goal of the library is to hide implementation details of various internet routers. For that reason, the library has a "Proxy" factory method which takes the IP of a router as parameter. The factory then probes the device using a set of possible proxies. Usually, there is one proxy which immediately knows that is is able to send commands to this device. All others usually take some time to return (given a timeout). One thought was already to simply query the device for an identifier, and then select the proper proxy using that, but in order to do so, you would already need to know how to query the device. Abstracting this knowledge is one of the main purposes of the library, so that becomes a little bit of a "circular-requirement"/deadlock: To connect to a device, you need to know what proxy to use, and to know what proxy to create, you need to connect to a device. So probing the device is - as we can see - the best solution so far, apart from keeping a lookup-table somewhere. The library currently kills all remaining processes once a valid proxy has been found. And yes, there is always only one good proxy per device. Currently there are about 12 proxies. So if one create a proxy instance using the factory, 12 sub-processes are spawned. So far, this has been really useful and worked very well. But recently someone else wanted to use this library to "broadcast" a command to all devices. So he took the library, and wrote his own multi-processed script. This obviously spawned 12 * n processes where n is the number of IPs to which he broadcasted. This has given us two problems: The host on which the command was executed slowed down to a near halt. Aborting the script with CTRL+C ground the system to a total halt. Not even the hardware console responded anymore! This may be due to some Python strangeness which still needs to be investigated. Maybe related to http://bugs.python.org/issue8296 The big underlying question, is how to design a library which does multi-processing, so other applications which use this library and want to be multi-processed themselves do not run into system limitations. My first thought was to require a pool to be passed to the library, and execute all tasks in that pool. In that way, the person using the library has control over the usage of system resources. But my gut tells me that there must be a better solution. Disclaimer: My experience with multiprocessing is fairly limited. I have implemented a few straightforward which did not require access control to resources. So I have not yet any practical experience with semaphores or mutexes. p.s.: In the future, we may have enough information to do this without the probing. But the database which would contain the proper information is not yet operational. Also, the design about multiprocessing a multiprocessed library intrigues me :)

• All my emails to Yahoo!, Hotmail and AOL are going to Spam, though I've implemented every validation

  - by Chetan

  Hi, I've implemented everything and checked everything (SPF, DomainKey, DKIM, reverse lookup), and only Gmail is allowing my emails to go to Inbox.

• How to set up dual quadro cards on RHEL 5.5?

  - by Alex J. Roberts

  I have a RHEL 5 workstation with 2 nvidia Quadro FX4500 cards, with one display attached to each card. After doing a clean install of RHEL 5.5, the second display doesnt work (it worked ok in RHEL 5.2). Neither separate X screens nor Xinerama are working. The kernel version is 2.6.18-194.el5 I've tried nvidia drivers 185.18.36 (the ones that i was using on 5.2) and the latest 260.19.36 and neither works. My xorg.conf is as follows: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (buildmeister@builder58) Fri Aug 14 18:34:43 PDT 2009 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" FontPath "unix/:7100" EndSection Section "ServerFlags" Option "Xinerama" "1" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/input/mice" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from data in "/etc/sysconfig/keyboard" Identifier "Keyboard0" Driver "kbd" Option "XkbLayout" "us" Option "XkbModel" "pc105" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "DELL 3007WFP" HorizSync 49.3 - 98.5 VertRefresh 60.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor1" VendorName "Unknown" ModelName "DELL 3007WFP" HorizSync 49.3 - 98.5 VertRefresh 60.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro FX 4500" BusID "PCI:10:0:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro FX 4500" BusID "PCI:129:0:0" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection And the Xorg Log: X Window System Version 7.1.1 Release Date: 12 May 2006 X Protocol Version 11, Revision 0, Release 7.1.1 Build Operating System: Linux 2.6.18-164.11.1.el5 x86_64 Red Hat, Inc.

• Packet logging on PIX firewall

  - by georged.id.auindex.htm

  We have a Cisco PIX 515 firewall and I would like to set up a simple logging that would give us a traffic breakdown for billing by: source destination protocol port size time PIX is plugged into Catalyst 2970 and I was told that the best thing since sliced bread for logging is to get Netflow and get Catalyst to log. My concern, however, (besides the Netflow cost) is that I really don't want to "listen" to the internal noise and all I'm interested in are the external traffic stats above for billing and analysis purposes. What would be the simplest and the easiest solution? Cheers George

• How do you set Android ViewPager to encompass only one View or Layout?

  - by Kyle

  I am struggling with the concepts needed to properly implement a view pager. By following some tutorials and referencing developer.android.com, I am able to get a view pager almost fully functional. The pager will flip through several text views that have been setup to say "My Message 0" through "My Message 9". The problem is that the view pager also flips the button on the bottom of the activity and the red block that is right above the button. I would like to have the view pager only cycle through the text. Would you please help me understand what I'm doing wrong? I have an activity that represents a dashboard: public class DashBoard extends FragmentActivity { private static final int NUMBER_OF_PAGES = 10; private ViewPager mViewPager; private MyFragmentPagerAdapter mMyFragmentPagerAdapter; public void onCreate(Bundle icicle){ super.onCreate(icicle); setContentView(R.layout.dashboard); mViewPager = (ViewPager) findViewById(R.id.viewpager); mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mMyFragmentPagerAdapter); } private static class MyFragmentPagerAdapter extends FragmentPagerAdapter{ public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int index) { return PageFragment.newInstance("My Message " + index); } @Override public int getCount(){ return NUMBER_OF_PAGES; } } and a class for the page fragment: public class PageFragment extends Fragment { public static PageFragment newInstance(String title){ PageFragment pageFragment = new PageFragment(); Bundle bundle = new Bundle(); bundle.putString("title", title); pageFragment.setArguments(bundle); return pageFragment; } @Override public void onCreate(Bundle icicle){ super.onCreate(icicle); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle icicle){ View view = inflater.inflate(R.layout.dashboard, container, false); TextView textView = (TextView) view.findViewById(R.id.textViewPage); textView.setText(getArguments().getString("title")); return view; } } and finally, my xml for the dashboard: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/dashbaordLabel" android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" /> <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> <Button android:id="@+id/newGoalButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/stringNewGoal" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:onClick="createNewGoal" /> <RelativeLayout android:id="@+id/SpaceBottom" android:layout_width="match_parent" android:layout_height="75dp" android:layout_above="@id/newGoalButton" android:background="@color/red" > </RelativeLayout> </RelativeLayout> A note about my xml, I tried wrapping the text view in some view pager tags eg: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" > <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> </android.support.v4.view.ViewPager> But all that did was make the text view disappear from the screen, while the button and red block still cycled as in the original issue.

• ASP.NET: Button in user control not posting back

  - by Ronnie Overby

  I have a simple user control with this code: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="Pager.ascx.cs" Inherits="Pager" %> <table style="width: 100%;"> <tr> <td runat="server" id="PageControls"> <!-- This button has the problem: --> <asp:Button ID="btnPrevPage" runat="server" Text="&larr;" OnClick="btnPrevPage_Click" /> Page <asp:DropDownList runat="server" ID="ddlPage" AutoPostBack="true" OnSelectedIndexChanged="ddlPage_SelectedIndexChanged" /> of <asp:Label ID="lblTotalPages" runat="server" /> <!-- This button has the problem: --> <asp:Button ID="btnNextPage" runat="server" Text="&rarr;" OnClick="btnNextPage_Click" /> </td> <td align="right" runat="server" id="itemsPerPageControls"> <asp:Literal ID="perPageText1" runat="server" /> <asp:DropDownList ID="ddlItemsPerPage" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlItemsPerPage_SelectedIndexChanged" /> <asp:Literal ID="perPageText2" runat="server" /> </td> </tr> </table> As you can see, the 2 buttons are wired to click events, which are defined correctly in the code-behind. Now, here is how I include an instance of the control on my page: <uc:Pager ID="Pager1" runat="server" TotalRecords="100" DisplayItemsPerPage="true" ItemsPerPageChoices="10,25,50,100" ItemsPerPageFormatString="Sessions/Page: {0}" PageSize="25" OnPageChanged="PageChanged" OnPageSizeChanged="PageChanged" /> I noticed though, that the 2 buttons in my user control weren't causing a post back when clicked. The drop down list does cause postback, though. Here is the rendered HTML: <table style="width: 100%;"> <tr> <td id="ctl00_MainContent_Pager1_PageControls" align="left"> <!-- No onclick event! Why? --> <input type="submit" name="ctl00$MainContent$Pager1$btnPrevPage" value="?" id="ctl00_MainContent_Pager1_btnPrevPage" /> Page <select name="ctl00$MainContent$Pager1$ddlPage" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$Pager1$ddlPage\',\'\')', 0)" id="ctl00_MainContent_Pager1_ddlPage"> <option value="1">1</option> <option selected="selected" value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> </select> of <span id="ctl00_MainContent_Pager1_lblTotalPages">6</span> <!-- No onclick event! Why? --> <input type="submit" name="ctl00$MainContent$Pager1$btnNextPage" value="?" id="ctl00_MainContent_Pager1_btnNextPage" /> </td> <td id="ctl00_MainContent_Pager1_itemsPerPageControls" align="right"> Sessions/Page: <select name="ctl00$MainContent$Pager1$ddlItemsPerPage" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$Pager1$ddlItemsPerPage\',\'\')', 0)" id="ctl00_MainContent_Pager1_ddlItemsPerPage"> <option value="10">10</option> <option selected="selected" value="25">25</option> <option value="50">50</option> <option value="100">100</option> </select> </td> </tr> </table> And, as you can see, there is no onclick attribute being rendered in the button's input elements. Why not?

• How to parse HTML with TouchXML or some other alternative.

  - by 0SX

  Hi, I'm trying to parse the HTML presented below with TouchXML but it keeps crashing when I try to extract certain attributes. I'm totally new to the parser world so I apologize for being a complete idiot. I need help to parse this HTML. What I'm trying to accomplish is to parse each attribute and value or what not and copy them to a string. I've been trying to find a good parser to parse HTML and I believe TouchXML is the best I've seen because of Tidy. Speaking of Tidy, How could I run this HTML through Tidy first then parse it? I'm not sure how to do this. Here is the code that I have so far that doesn't work due to it's not pulling everything I need from the HTML. Any help or advice would be much appreciated. Thanks My current code: NSMutableArray *res = [[NSMutableArray alloc] init]; // using local resource file NSString *XMLPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"example.html"]; NSData *XMLData = [NSData dataWithContentsOfFile:XMLPath]; CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease]; NSArray *nodes = NULL; nodes = [doc nodesForXPath:@"//div" error:nil]; for (CXMLElement *node in nodes) { NSMutableDictionary *item = [[NSMutableDictionary alloc] init]; [item setObject:[[node attributeForName:@"id"] stringValue] forKey:@"id"]; [res addObject:item]; [item release]; } NSLog(@"%@", res); [res release]; HTML file that needs to be parsed: <html> <head> <base target="_blank" /> </head> <body style="margin:2;"> <div id="group"> <div id="groupURL"><a href="http://www.example.com/groups">Group URL</a></div> <img id="grouplogo" src="http://images.example.com/groups/image.png" /> <div id="groupcomputer"><a href="http://www.example.com/groups/page" title="Group Title">Group title this would be here</a></div> <div id="groupinfos"> <div id="groupinfo-l">Person</div><div id="groupinfo-r">Ralph</div> <div id="groupinfo-l">Years</div><div id="groupinfo-r">4 years</div> <div id="groupinfo-l">Salary</div><div id="groupinfo-r">100K</div> <div id="groupinfo-l">Other</div><div id="groupoth" style="width:15px">other info</div> </body> </html> EDIT: I could use Element Parser but I need to know how to extract the Person's Name from the following example which would be Ralph in this case. <div id="groupinfo-l">Person</div><div id="groupinfo-r">Ralph</div>

• Overriding Object.Equals() instance method in C#; now Code Analysis / FxCop warning CA2218: "should

  - by Chris W. Rea

  I've got a complex class in my C# project on which I want to be able to do equality tests. It is not a trivial class; it contains a variety of scalar properties as well as references to other objects and collections (e.g. IDictionary). For what it's worth, my class is sealed. To enable a performance optimization elsewhere in my system (an optimization that avoids a costly network round-trip), I need to be able to compare instances of these objects to each other for equality – other than the built-in reference equality – and so I'm overriding the Object.Equals() instance method. However, now that I've done that, Visual Studio 2008's Code Analysis a.k.a. FxCop, which I keep enabled by default, is raising the following warning: warning : CA2218 : Microsoft.Usage : Since 'MySuperDuperClass' redefines Equals, it should also redefine GetHashCode. I think I understand the rationale for this warning: If I am going to be using such objects as the key in a collection, the hash code is important. i.e. see this question. However, I am not going to be using these objects as the key in a collection. Ever. Feeling justified to suppress the warning, I looked up code CA2218 in the MSDN documentation to get the full name of the warning so I could apply a SuppressMessage attribute to my class as follows: [SuppressMessage("Microsoft.Naming", "CA2218:OverrideGetHashCodeOnOverridingEquals", Justification="This class is not to be used as key in a hashtable.")] However, while reading further, I noticed the following: How to Fix Violations To fix a violation of this rule, provide an implementation of GetHashCode. For a pair of objects of the same type, you must ensure that the implementation returns the same value if your implementation of Equals returns true for the pair. When to Suppress Warnings ----- Do not suppress a warning from this rule. [arrow & emphasis mine] So, I'd like to know: Why shouldn't I suppress this warning as I was planning to? Doesn't my case warrant suppression? I don't want to code up an implementation of GetHashCode() for this object that will never get called, since my object will never be the key in a collection. If I wanted to be pedantic, instead of suppressing, would it be more reasonable for me to override GetHashCode() with an implementation that throws a NotImplementedException? Update: I just looked this subject up again in Bill Wagner's good book Effective C#, and he states in "Item 10: Understand the Pitfalls of GetHashCode()": If you're defining a type that won't ever be used as the key in a container, this won't matter. Types that represent window controls, web page controls, or database connections are unlikely to be used as keys in a collection. In those cases, do nothing. All reference types will have a hash code that is correct, even if it is very inefficient. [...] In most types that you create, the best approach is to avoid the existence of GetHashCode() entirely. ... that's where I originally got this idea that I need not be concerned about GetHashCode() always.

• Issue with XSL Criteria

  - by Rachel

  I am using the below piece of XSL to select the id of the text nodes whose content has a given index. This index value in input will be relative to a spcified node whose id value is known. The criteria to select the text node is, The text node content should contain a index say 'i' relative to node say 'n' whose id value i know. 'i' and 'id of n' is got as index and nodeName from the input param as seen in the xsl. Node 'd1e5' has the text content whose index ranges from 1 to 33. When i give an index value greater than 33 i want the below criteria to fail but it does not, [sum((preceding::text(), .)[normalize-space()][. >> //*[@id=$nodeName]]/string-length(.)) ge $index] Input xml: <?xml version="1.0" encoding="UTF-8"?> <html xmlns="http://www.w3.org/1999/xhtml" id="d1e1"> <head id="d1e3"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title id="d1e5">Every document must have a title</title> </head> <body id="d1e9"> <h1 id="d1e11" align="center">Very Important Heading</h1> <p id="d1e13">Since this is just a sample, I won't put much text here.</p> </body> </html> XSL code used: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsd="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xsd" version="2.0"> <xsl:param name="insert-file" as="node()+"> <insert-data><data index="1" nodeName="d1e5"></data><data index="34" nodeName="d1e5"></data></insert-data> </xsl:param> <xsl:param name="nodeName" as="xsd:string" /> <xsl:variable name="main-root" as="document-node()" select="/"/> <xsl:variable name="insert-data" as="element(data)*"> <xsl:for-each select="$insert-file/insert-data/data"> <xsl:sort select="xsd:integer(@index)"/> <xsl:variable name="index" select="xsd:integer(@index)" /> <xsl:variable name="nodeName" select="@nodeName" /> <data text-id="{generate-id($main-root/descendant::text()[sum((preceding::text(), .)[normalize-space()][. >> //*[@id=$nodeName]]/string-length(.)) ge $index][1])}"> </data> </xsl:for-each> </xsl:variable> <xsl:template match="/"> <Output> <xsl:copy-of select="$insert-data" /> </Output> </xsl:template> </xsl:stylesheet> Actual output: <?xml version="1.0" encoding="UTF-8"?> <Output> <data text-id="d1t8"/> <data text-id="d1t14"/> </Output> Expected output: <?xml version="1.0" encoding="UTF-8"?> <Output> <data text-id="d1t8"/> </Output> This solution works fine if index lies between 1 and 33. Any index value greater that 33 causes incorrect text nodes to get selected. I could not understand why the text node 'd1t14' is getting selected. Please share your thoughts.

• Hibernate many-to-many mapping not saved in pivot table

  - by vincent

  I having problems saving many to many relationships to a pivot table. The way the pojos are created is unfortunately a pretty long process which spans over a couple of different threads which work on the (to this point un-saved) object until it is finally persisted. I associate the related objects to one another right after they are created and when debugging I can see the List of related object populated with their respective objects. So basically all is fine to this point. When I persist the object everything get saved except the relations in the pivot table. mapping files: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.thebeansgroup.jwinston.plugin.orm.hibernate.object"> <class name="ShowObject" table="show_object"> <id name="id"> <generator class="native" /> </id> <property name="name" /> <set cascade="all" inverse="true" name="venues" table="venue_show"> <key column="show_id"/> <many-to-many class="VenueObject"/> </set> </class> </hibernate-mapping> and the other <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.thebeansgroup.jwinston.plugin.orm.hibernate.object"> <class name="VenueObject" table="venue_object"> <id name="id"> <generator class="native"/> </id> <property name="name"/> <property name="latitude" type="integer"/> <property name="longitude" type="integer"/> <set cascade="all" inverse="true" name="shows" table="venue_show"> <key column="venue_id"/> <many-to-many class="ShowObject"/> </set> </class> </hibernate-mapping> pojos: public class ShowObject extends OrmObject { private Long id; private String name; private Set venues; public ShowObject() { } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Set getVenues() { return venues; } public void setVenues(Set venues) { this.venues = venues; } } and the other: public class VenueObject extends OrmObject { private Long id; private String name; private int latitude; private int longitude; private Set shows = new HashSet(); public VenueObject() { } @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } public void setId(Long id) { this.id = id; } public int getLatitude() { return latitude; } public void setLatitude(int latitude) { this.latitude = latitude; } public int getLongitude() { return longitude; } public void setLongitude(int longitude) { this.longitude = longitude; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Set getShows() { return shows; } public void setShows(Set shows) { this.shows = shows; } } Might the problem be related to the lack of annotations?

• Why is SQLite3 using covering indices instead of the indices I created?

  - by Geoff

  I have an extremely large database (contacts has ~3 billion entries, people has ~280 million entries, and the other tables have a negligible number of entries). Most other queries I've run are really fast. However, I've encountered a more complicated query that's really slow. I'm wondering if there's any way to speed this up. First of all, here is my schema: CREATE TABLE activities (id INTEGER PRIMARY KEY, name TEXT NOT NULL); CREATE TABLE contacts ( id INTEGER PRIMARY KEY, person1_id INTEGER NOT NULL, person2_id INTEGER NOT NULL, duration REAL NOT NULL, -- hours activity_id INTEGER NOT NULL -- FOREIGN_KEY(person1_id) REFERENCES people(id), -- FOREIGN_KEY(person2_id) REFERENCES people(id) ); CREATE TABLE people ( id INTEGER PRIMARY KEY, state_id INTEGER NOT NULL, county_id INTEGER NOT NULL, age INTEGER NOT NULL, gender TEXT NOT NULL, -- M or F income INTEGER NOT NULL -- FOREIGN_KEY(state_id) REFERENCES states(id) ); CREATE TABLE states ( id INTEGER PRIMARY KEY, name TEXT NOT NULL, abbreviation TEXT NOT NULL ); CREATE INDEX activities_name_index on activities(name); CREATE INDEX contacts_activity_id_index on contacts(activity_id); CREATE INDEX contacts_duration_index on contacts(duration); CREATE INDEX contacts_person1_id_index on contacts(person1_id); CREATE INDEX contacts_person2_id_index on contacts(person2_id); CREATE INDEX people_age_index on people(age); CREATE INDEX people_county_id_index on people(county_id); CREATE INDEX people_gender_index on people(gender); CREATE INDEX people_income_index on people(income); CREATE INDEX people_state_id_index on people(state_id); CREATE INDEX states_abbreviation_index on states(abbreviation); CREATE INDEX states_name_index on states(name); Note that I've created an index on every column in the database. I don't care about the size of the database; speed is all I care about. Here's an example of a query that, as expected, runs almost instantly: SELECT count(*) FROM people, states WHERE people.state_id=states.id and states.abbreviation='IA'; Here's the troublesome query: SELECT * FROM contacts WHERE rowid IN (SELECT contacts.rowid FROM contacts, people, states WHERE contacts.person1_id=people.id AND people.state_id=states.id AND states.name='Kansas' INTERSECT SELECT contacts.rowid FROM contacts, people, states WHERE contacts.person2_id=people.id AND people.state_id=states.id AND states.name='Missouri'); Now, what I think would happen is that each subquery would use each relevant index I've created to speed this up. However, when I show the query plan, I see this: sqlite> EXPLAIN QUERY PLAN SELECT * FROM contacts WHERE rowid IN (SELECT contacts.rowid FROM contacts, people, states WHERE contacts.person1_id=people.id AND people.state_id=states.id AND states.name='Kansas' INTERSECT SELECT contacts.rowid FROM contacts, people, states WHERE contacts.person2_id=people.id AND people.state_id=states.id AND states.name='Missouri'); 0|0|0|SEARCH TABLE contacts USING INTEGER PRIMARY KEY (rowid=?) (~25 rows) 0|0|0|EXECUTE LIST SUBQUERY 1 2|0|2|SEARCH TABLE states USING COVERING INDEX states_name_index (name=?) (~1 rows) 2|1|1|SEARCH TABLE people USING COVERING INDEX people_state_id_index (state_id=?) (~5569556 rows) 2|2|0|SEARCH TABLE contacts USING COVERING INDEX contacts_person1_id_index (person1_id=?) (~12 rows) 3|0|2|SEARCH TABLE states USING COVERING INDEX states_name_index (name=?) (~1 rows) 3|1|1|SEARCH TABLE people USING COVERING INDEX people_state_id_index (state_id=?) (~5569556 rows) 3|2|0|SEARCH TABLE contacts USING COVERING INDEX contacts_person2_id_index (person2_id=?) (~12 rows) 1|0|0|COMPOUND SUBQUERIES 2 AND 3 USING TEMP B-TREE (INTERSECT) In fact, if I show the query plan for the first query I posted, I get this: sqlite> EXPLAIN QUERY PLAN SELECT count(*) FROM people, states WHERE people.state_id=states.id and states.abbreviation='IA'; 0|0|1|SEARCH TABLE states USING COVERING INDEX states_abbreviation_index (abbreviation=?) (~1 rows) 0|1|0|SEARCH TABLE people USING COVERING INDEX people_state_id_index (state_id=?) (~5569556 rows) Why is SQLite using covering indices instead of the indices I created? Shouldn't the search in the people table be able to happen in log(n) time given state_id which in turn is found in log(n) time?

• Make wix installation set upgrade to same folder

  - by Magnus Akselvoll

  How can I make a major upgrade to an installation set (MSI) built with Wix install into the same folder as the original installation? The installation is correctly detected as an upgrade, but the directory selection screen is still shown and with the default value (not necessarily the current installation folder). Do I have to do manual work like saving the installation folder in a registry key upon first installing and then read this key upon upgrade? If so, is there any example? Or is there some easier way to achieve this in MSI / Wix? As reference I paste in my current Wix file below: <?xml version="1.0" encoding="utf-8"?> <!-- Package information --> <Package Keywords="Installer" Id="e85e6190-1cd4-49f5-8924-9da5fcb8aee8" Description="Installs MyCompany Integration Framework 1.0.0" Comments="Installs MyCompany Integration Framework 1.0.0" InstallerVersion="100" Compressed="yes" /> <Upgrade Id='9071eacc-9b5a-48e3-bb90-8064d2b2c45d'> <UpgradeVersion Property="PATCHFOUND" OnlyDetect="no" Minimum="0.0.1" IncludeMinimum="yes" Maximum="1.0.0" IncludeMaximum="yes"/> </Upgrade> <!-- Useless but necessary... --> <Media Id="1" Cabinet="MyCompany.cab" EmbedCab="yes" /> <!-- Precondition: .Net 2 must be installed --> <Condition Message='This setup requires the .NET Framework 2 or higher.'> <![CDATA[MsiNetAssemblySupport >= "2.0.50727"]]> </Condition> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="MyCompany" Name="MyCompany"> <Directory Id="INSTALLDIR" Name="Integrat" LongName="MyCompany Integration Framework"> <Component Id="MyCompanyDllComponent" Guid="4f362043-03a0-472d-a84f-896522ce7d2b" DiskId="1"> <File Id="MyCompanyIntegrationDll" Name="IbIntegr.dll" src="..\Build\MyCompany.Integration.dll" Vital="yes" LongName="MyCompany.Integration.dll" /> <File Id="MyCompanyServiceModelDll" Name="IbSerMod.dll" src="..\Build\MyCompany.ServiceModel.dll" Vital="yes" LongName="MyCompany.ServiceModel.dll" /> </Component> <!-- More components --> </Directory> </Directory> </Directory> <Feature Id="MyCompanyProductFeature" Title='MyCompany Integration Framework' Description='The complete package' Display='expand' Level="1" InstallDefault='local' ConfigurableDirectory="INSTALLDIR"> <ComponentRef Id="MyCompanyDllComponent" /> </Feature> <!-- Task scheduler application.

• PHP-How to Pass Multiple Value In Form Field

  - by Tall boY

  hi i have a php based sorting method with drop down menu to sort no of rows, it is working fine. i have another sorting links to sort id & title, it is also working fine. but together they are not working fine. what happens is that when i sort(say by title) using links, result gets sorted by title, then if i sort rows using drop down menu rows get sorted but result gets back to default of id sort. sorting codes for id & tite is if ($orderby == 'title' && $sortby == 'asc') {echo " <li id='scurrent'><a href='?rpp=$rowsperpage&order=title&sort=asc'>title-asc:</a></li> ";} else {echo " <li><a href='?rpp=$rowsperpage&order=title&sort=asc'>title-asc:</a></li> ";} if ($orderby == 'title' && $sortby == 'desc') {echo " <li id='scurrent'><a href='?rpp=$rowsperpage&order=title&sort=desc'>title-desc:</a></li> ";} else {echo " <li><a href='?rpp=$rowsperpage&order=title&sort=desc'>title-desc:</a></li> ";} if ($orderby == 'id' && $sortby == 'asc') {echo " <li id='scurrent'><a href='?rpp=$rowsperpage&order=id&sort=asc'>id-asc:</a></li> ";} else {echo " <li><a href='?rpp=$rowsperpage&order=id&sort=asc'>id-asc:</a></li> ";} if ($orderby == 'id' && $sortby == 'desc') {echo " <li id='scurrent'><a href='?rpp=$rowsperpage&order=id&sort=desc'>id-desc:</a></li> ";} else {echo " <li><a href='?rpp=$rowsperpage&order=id&sort=desc'>id-desc:</a></li> ";} ?> sorting codes for rows is <form action="is-test.php" method="get"> <select name="rpp" onchange="this.form.submit()"> <option value="10" <?php if ($rowsperpage == 10) echo 'selected="selected"' ?>>10</option> <option value="20" <?php if ($rowsperpage == 20) echo 'selected="selected"' ?>>20</option> <option value="30" <?php if ($rowsperpage == 30) echo 'selected="selected"' ?>>30</option> </select> </form> this method passes only rows per page(rpp) into url. i want it to pass order, sort& rpp. is there a way around to pass multiple values in form fields like this. <form action="is-test.php" method="get"> <select name="rpp, order, sort" onchange="this.form.submit()"> <option value="10, $orderby, $sortby" <?php if ($rowsperpage == 10) echo 'selected="selected"' ?>>10</option> <option value="20, $orderby, $sortby" <?php if ($rowsperpage == 20) echo 'selected="selected"' ?>>20</option> <option value="30, $orderby, $sortby" <?php if ($rowsperpage == 30) echo 'selected="selected"' ?>>30</option> </select> </form> this may seem silly but it just to give you an idea of what i am trying to implement,(i am very new to php) please suggest any way to make this work. thanks

• EHome IR receiver and Ubuntu 13 - any one have this working?

  - by squakie

  I have a "generic" USB IR receiver I purchased off of Ebay to make my life a little easier with XBMC on my Ubuntu box. I am currently running 13.10 and have never tried nor have any knowledge of IR in Ubuntu. I know of lirc, and I know a lot of it is now included in the kernel. My understanding is that lirc in basic terms maps pulses from an remote control to functions - like keyboard or mouse clicks. It is also my understanding that I might still need a driver or something for my device. lsusb shows the device as: Bus 006 Device 003: ID 147a:e016 Formosa Industrial Computing, Inc. eHome Infrared Receiver dmesg shows the following pertaining to the device: [43635.311985] usb 6-2: USB disconnect, device number 2 [43641.344387] usb 6-2: new full-speed USB device number 3 using ohci-pci [43641.543454] usb 6-2: New USB device found, idVendor=147a, idProduct=e016 [43641.543467] usb 6-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [43641.543473] usb 6-2: Product: eHome Infrared Transceiver [43641.543478] usb 6-2: Manufacturer: Formosa21 [43641.543483] usb 6-2: SerialNumber: FM000623 [43641.555736] Registered IR keymap rc-rc6-mce [43641.555968] input: Media Center Ed. eHome Infrared Remote Transceiver (147a:e016) as /devices/pci0000:00/0000:00:12.0/usb6/6-2/6-2:1.0/rc/rc2/input15 [43641.556221] rc2: Media Center Ed. eHome Infrared Remote Transceiver (147a:e016) as /devices/pci0000:00/0000:00:12.0/usb6/6-2/6-2:1.0/rc/rc2 [43641.556584] input: MCE IR Keyboard/Mouse (mceusb) as /devices/virtual/input/input16 [43641.557186] rc rc2: lirc_dev: driver ir-lirc-codec (mceusb) registered at minor = 0 [43641.731965] mceusb 6-2:1.0: Registered Formosa21 eHome Infrared Transceiver with mce emulator interface version 1 [43641.731978] mceusb 6-2:1.0: 2 tx ports (0x0 cabled) and 2 rx sensors (0x0 active) (excuse the double spacing, but I had to put in extra cr/lf using "enter" or the entire thing was just one long unreadable string). When I connect the same IR receiver to a Raspberry Pi running OpenELEC/XBMC there is no flashing led unless I press a remote button, and the device works. In Ubuntu, the led is constantly blinking, and nothing happens when I press a remote key. I tried the command line program to test but it never echoes anything back to the terminal window. I believe it must need some sort of driver or something else, but I am completely in the dark on this. If it matters I also have: - Logitech wireless keyboard/mouse USB receiver - Tenda USB wireless adapter And.....I've also noticed some errors now that show in dmesg that seem to somehow related to HDMI if that makes any sense: 46721.144731] HDMI: ELD buf size is 0, force 128 [46721.144749] HDMI: invalid ELD data byte 0 [46721.444025] HDMI: ELD buf size is 0, force 128 [46721.444061] HDMI: invalid ELD data byte 0 [46721.743375] HDMI: ELD buf size is 0, force 128 [46721.743411] HDMI: invalid ELD data byte 0 [46722.043092] HDMI: ELD buf size is 0, force 128 [46722.043118] HDMI: invalid ELD data byte 0 [46722.343086] HDMI: ELD buf size is 0, force 128 [46722.343122] HDMI: invalid ELD data byte 0 [46722.642517] HDMI: ELD buf size is 0, force 128 [46722.642574] HDMI: invalid ELD data byte 0 [46722.942459] HDMI: ELD buf size is 0, force 128 [46722.942485] HDMI: invalid ELD data byte 0 [46723.242103] HDMI: ELD buf size is 0, force 128 [46723.242129] HDMI: invalid ELD data byte 0 [46723.541877] HDMI: ELD buf size is 0, force 128 [46723.541923] HDMI: invalid ELD data byte 0 [58366.651954] HDMI: ELD buf size is 0, force 128 [58366.651980] HDMI: invalid ELD data byte 0 [58366.951523] HDMI: ELD buf size is 0, force 128 [58366.951549] HDMI: invalid ELD data byte 0 [58367.251075] HDMI: ELD buf size is 0, force 128 [58367.251121] HDMI: invalid ELD data byte 0 [58367.550517] HDMI: ELD buf size is 0, force 128 [58367.550563] HDMI: invalid ELD data byte 0 [58367.850219] HDMI: ELD buf size is 0, force 128 [58367.850256] HDMI: invalid ELD data byte 0 [58368.150160] HDMI: ELD buf size is 0, force 128 [58368.150185] HDMI: invalid ELD data byte 0 [58368.449544] HDMI: ELD buf size is 0, force 128 [58368.449570] HDMI: invalid ELD data byte 0 [58368.749583] HDMI: ELD buf size is 0, force 128 [58368.749629] HDMI: invalid ELD data byte 0 [58369.049280] HDMI: ELD buf size is 0, force 128 [58369.049326] HDMI: invalid ELD data byte 0 [58394.706273] HDMI: ELD buf size is 0, force 128 [58394.706300] HDMI: invalid ELD data byte 0 [58394.706350] HDMI: ELD buf size is 0, force 128 [58394.706367] HDMI: invalid ELD data byte 0 [58395.003032] HDMI: ELD buf size is 0, force 128 [58395.003058] HDMI: invalid ELD data byte 0 [58395.302680] HDMI: ELD buf size is 0, force 128 [58395.302705] HDMI: invalid ELD data byte 0 [58395.602442] HDMI: ELD buf size is 0, force 128 [58395.602477] HDMI: invalid ELD data byte 0 [58395.902143] HDMI: ELD buf size is 0, force 128 [58395.902179] HDMI: invalid ELD data byte 0 [58396.201839] HDMI: ELD buf size is 0, force 128 [58396.201875] HDMI: invalid ELD data byte 0 [58396.501538] HDMI: ELD buf size is 0, force 128 [58396.501574] HDMI: invalid ELD data byte 0 [58396.801232] HDMI: ELD buf size is 0, force 128 [58396.801268] HDMI: invalid ELD data byte 0 [58397.100583] HDMI: ELD buf size is 0, force 128 [58397.100627] HDMI: invalid ELD data byte 0 [63095.766042] systemd-hostnamed[8875]: Warning: nss-myhostname is not installed.

• I have a problem with a AE1200 Cisco/Linksys Wireless-N USB adapter having stopped working after I ran the update manager in Ubuntu 12.04

  - by user69670

  Here is the problem, I use a Cisco/Linksys AE1200 wireless network adapter to connect my desktop to a public wifi internet connection. I use ndiswrapper to use the windows driver and it had been working fine for me untill I ran the update manager overnight a few days ago. When I woke up it was asking for the normal computer restart to implement the changes but after rebooting the computer, the wireless adapter did not work, the status light on the adapter did not light up even though ubuntu recognizes it is there and according to ndiswrapper the drivers are loaded and the hardware is present. the grep command is being a bitch for some unknown reason today so this will be long sorry Output from "lspci": 00:00.0 Host bridge: Advanced Micro Devices [AMD] nee ATI Radeon Xpress 200 Host Bridge (rev 01) 00:01.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RS480 PCI Bridge 00:12.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB600 Non-Raid-5 SATA 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI0) 00:13.1 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI1) 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI2) 00:13.3 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI3) 00:13.4 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI4) 00:13.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB Controller (EHCI) 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 13) 00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI SB600 IDE 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB600 PCI to LPC Bridge 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RC410 [Radeon Xpress 200] 02:02.0 Communication controller: Conexant Systems, Inc.

• Why do I get an exception when playing multiple sound instances?

  - by Boreal

  Right now, I'm adding a rudimentary sound engine to my game. So far, I am able to load in a WAV file and play it once, then free up the memory when I close the game. However, the game crashes with a nice ArgumentOutOfBoundsException when I try to play another sound instance. Specified argument was out of the range of valid values. Parameter name: readLength I'm following this tutorial pretty much exactly, but I still keep getting the aforementioned error. Here's my sound-related code. /// <summary> /// Manages all sound instances. /// </summary> public static class Audio { static XAudio2 device; static MasteringVoice master; static List<SoundInstance> instances; /// <summary> /// The XAudio2 device. /// </summary> internal static XAudio2 Device { get { return device; } } /// <summary> /// Initializes the audio device and master track. /// </summary> internal static void Initialize() { device = new XAudio2(); master = new MasteringVoice(device); instances = new List<SoundInstance>(); } /// <summary> /// Releases all XA2 resources. /// </summary> internal static void Shutdown() { foreach(SoundInstance i in instances) i.Dispose(); master.Dispose(); device.Dispose(); } /// <summary> /// Registers a sound instance with the system. /// </summary> /// <param name="instance">Sound instance</param> internal static void AddInstance(SoundInstance instance) { instances.Add(instance); } /// <summary> /// Disposes any sound instance that has stopped playing. /// </summary> internal static void Update() { List<SoundInstance> temp = new List<SoundInstance>(instances); foreach(SoundInstance i in temp) if(!i.Playing) { i.Dispose(); instances.Remove(i); } } } /// <summary> /// Loads sounds from various files. /// </summary> internal class SoundLoader { /// <summary> /// Loads a .wav sound file. /// </summary> /// <param name="format">The decoded format will be sent here</param> /// <param name="buffer">The data will be sent here</param> /// <param name="soundName">The path to the WAV file</param> internal static void LoadWAV(out WaveFormat format, out AudioBuffer buffer, string soundName) { WaveStream wave = new WaveStream(soundName); format = wave.Format; buffer = new AudioBuffer(); buffer.AudioData = wave; buffer.AudioBytes = (int)wave.Length; buffer.Flags = BufferFlags.EndOfStream; } } /// <summary> /// Manages the data for a single sound. /// </summary> public class Sound : IAsset { WaveFormat format; AudioBuffer buffer; /// <summary> /// Loads a sound from a file. /// </summary> /// <param name="soundName">The path to the sound file</param> /// <returns>Whether the sound loaded successfully</returns> public bool Load(string soundName) { if(soundName.EndsWith(".wav")) SoundLoader.LoadWAV(out format, out buffer, soundName); else return false; return true; } /// <summary> /// Plays the sound. /// </summary> public void Play() { Audio.AddInstance(new SoundInstance(format, buffer)); } /// <summary> /// Unloads the sound from memory. /// </summary> public void Unload() { buffer.Dispose(); } } /// <summary> /// Manages a single sound instance. /// </summary> public class SoundInstance { SourceVoice source; bool playing; /// <summary> /// Whether the sound is currently playing. /// </summary> public bool Playing { get { return playing; } } /// <summary> /// Starts a new instance of a sound. /// </summary> /// <param name="format">Format of the sound</param> /// <param name="buffer">Buffer holding sound data</param> internal SoundInstance(WaveFormat format, AudioBuffer buffer) { source = new SourceVoice(Audio.Device, format); source.BufferEnd += (s, e) => playing = false; source.Start(); source.SubmitSourceBuffer(buffer); // THIS IS WHERE THE EXCEPTION IS THROWN playing = true; } /// <summary> /// Releases memory used by the instance. /// </summary> internal void Dispose() { source.Dispose(); } } The exception occurs on line 156 when I am playing the sound: source.SubmitSourceBuffer(buffer);

• Deduping your redundancies

  - by nospam(at)example.com (Joerg Moellenkamp)

  Robin Harris of Storagemojo pointed to an interesting article about about deduplication and it's impact to the resiliency of your data against data corruption on ACM Queue. The problem in short: A considerable number of filesystems store important metadata at multiple locations. For example the ZFS rootblock is copied to three locations. Other filesystems have similar provisions to protect their metadata. However you can easily proof, that the rootblock pointer in the uberblock of ZFS for example is pointing to blocks with absolutely equal content in all three locatition (with zdb -uu and zdb -r). It has to be that way, because they are protected by the same checksum. A number of devices offer block level dedup, either as an option or as part of their inner workings. However when you store three identical blocks on them and the devices does block level dedup internally, the device may just deduplicated your redundant metadata to a block stored just once that is stored on the non-voilatile storage. When this block is corrupted, you have essentially three corrupted copies. Three hit with one bullet. This is indeed an interesting problem: A device doing deduplication doesn't know if a block is important or just a datablock. This is the reason why I like deduplication like it's done in ZFS. It's an integrated part and so important parts don't get deduplicated away. A disk accessed by a block level interface doesn't know anything about the importance of a block. A metadata block is nothing different to it's inner mechanism than a normal data block because there is no way to tell that this is important and that those redundancies aren't allowed to fall prey to some clever deduplication mechanism. Robin talks about this in regard of the Sandforce disk controllers who use a kind of dedup to reduce some of the nasty effects of writing data to flash, but the problem is much broader. However this is relevant whenever you are using a device with block level deduplication. It's just the point that you have to activate it for most implementation by command, whereas certain devices do this by default or by design and you don't know about it. However I'm not perfectly sure about that ? given that storage administration and server administration are often different groups with different business objectives I would ask your storage guys if they have activated dedup without telling somebody elase on their boxes in order to speak less often with the storage sales rep. The problem is even more interesting with ZFS. You may use ditto blocks to protect important data to store multiple copies of data in the pool to increase redundancy, even when your pool just consists out of one disk or just a striped set of disk. However when your device is doing dedup internally it may remove your redundancy before it hits the nonvolatile storage. You've won nothing. Just spend your disk quota on the the LUNs in the SAN and you make your disk admin happy because of the good dedup ratio However you can just fall in this specific "deduped ditto block"trap when your pool just consists out of a single device, because ZFS writes ditto blocks on different disks, when there is more than just one disk. Yet another reason why you should spend some extra-thought when putting your zpool on a single LUN, especially when the LUN is sliced and dices out of a large heap of storage devices by a storage controller. However I have one problem with the articles and their specific mention of ZFS: You can just hit by this problem when you are using the deduplicating device for the pool. However in the specifically mentioned case of SSD this isn't the usecase. Most implementations of SSD in conjunction with ZFS are hybrid storage pools and so rotating rust disk is used as pool and SSD are used as L2ARC/sZIL. And there it simply doesn't matter: When you really have to resort to the sZIL (your system went down, it doesn't matter of one block or several blocks are corrupt, you have to fail back to the last known good transaction group the device. On the other side, when a block in L2ARC is corrupt, you simply read it from the pool and in HSP implementations this is the already mentioned rust. In conjunction with ZFS this is more interesting when using a storage array, that is capable to do dedup and where you use LUNs for your pool. However as mentioned before, on those devices it's a user made decision to do so, and so it's less probable that you deduplicating your redundancies. Other filesystems lacking acapability similar to hybrid storage pools are more "haunted" by this problem of SSD using dedup-like mechanisms internally, because those filesystem really store the data on the the SSD instead of using it just as accelerating devices. However at the end Robin is correct: It's jet another point why protecting your data by creating redundancies by dispersing it several disks (by mirror or parity RAIDs) is really important. No dedup mechanism inside a device can dedup away your redundancy when you write it to a totally different and indepenent device.

• Getting instance crashes on IntelliJ IDEA with scala plugin.

  - by egervari

  I am building a scala web project using scala test, lift, jpa, hibernate, mercurial plugin, etc. I am getting instant crashes, where the ide just bombs, the window shuts down, and it gives no error messages whatsoever when I am doing any amount of copy/pasting of code. This started happening once my project got to about 100 unit tests. This problem is incredibly annoying, because when the crash happens, 30-60 seconds of activity is not saved. Even IDEA will forget which files were last opened and will forget where the cursor was, which makes it really hard to continue where you left off after the crash. A lot can happen in 60 seconds! Now, I've given up, because it seems like all sorts of things cause the IntelliJ IDEA to crash over and over. For example, if I were to copy and paste this code, to write a similar test for another collection type, it would crash shortly after: it should "cascade save and delete status messages" in { val statusMessage = new StatusMessage("message") var user = userDao.find(1).get user.addToStatusMessages(statusMessage) userDao.save(user) statusMessage.isPersistent should be (true) userDao.delete(user) statusMessageDao.find(statusMessage.id) should equal (None) } There is nothing special about this piece of code. It's code that is working just fine. However, IDEA bombs shortly after I paste something like this. For example, I might change StatusMessage to the new class I want to test cascading on... and then have to import that class into the test... and BOOM... it crashed. On windows 7, the IDEA window literally just minimizes and crashes with no warning. The next time I startup IDEA, it has no memory of what happened. Now, I've had this problem before. I posted it way back on IDEA's YouTrack. I was told to invalidate my caches. That never fixed it then, and it's not fixing it now. Please help. This error is fairly random, but it's happening constantly now. I could program for hours and not see it before... and the fact that my work just gets destroyed and I can't remember what I did during the last minute causes me to swear at my monitor at a db level higher than my stereo can go.

• DRBD on a disk with existing file system that takes all the place

  - by Karolis T.

  I'm currently trying to simulate the environment via XEN. I have installed two debian systems with such FS layout: cltest1:/etc# df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda2 6.0G 417M 5.2G 8% / tmpfs 257M 0 257M 0% /lib/init/rw udev 10M 16K 10M 1% /dev tmpfs 257M 4.0K 257M 1% /dev/shm Host cltest2 is identical. Here's my drbd.conf global { minor-count 1; } resource mysql { protocol C; syncer { rate 10M; # 10 Megabytes } on cltest1 { device /dev/drbd0; disk /dev/xvda2; address 192.168.1.186:7789; meta-disk internal; } on cltest2 { device /dev/drbd0; disk /dev/xvda2; address 192.168.1.187:7789; meta-disk internal; } } I have not created filesystem on drbd0 Starting DRBD via init.d script errors out with: Starting DRBD resources: [ d(mysql) /dev/drbd0: Failure: (114) Lower device is already claimed.

You need to either * use external meta data (recommended) * shrink that filesystem first * zero out the device (destroy the filesystem) Operation refused. Command 'drbdmeta /dev/drbd0 v08 /dev/xvda2 internal create-md' terminated with exit code 40 drbdadm aborting As I understand, all of my problems are because I don't have unallocated disk space on xvda2. What are my options besides shrinking FS and connecting a separate physical disk? Can't the meta-data be stored on a file in the local filesystem?
