  • C++ header file and function declaration ending in "= 0"

    - by Adam
    hi, I have the following code inside the .h file and I'm not sure what does the assignment statement do and how is it called properly? virtual void yield() = 0; I thought that the function returns a value of 0 by default but since this function returns void I am a little bit confused. Can anyone comment on this and maybe say how can I refer to this assignment, I mean how is it called in C++ jargon? Thanks.

  • Concurrent processes do not utilize all available CPU

    - by metdos
    I run some processes on an EC2 cc2.8xlarge instance which has 32 virtual processors. For some type of processes, when I run 16 processes on parallel, all of them use 100% of CPU cycles. But for other type of processes, they are not using 100% CPU and they finish considerably slower than a single thread. There is no time spend on IO and all data is served from memory. Do you have any idea about the reason of this problem?

  • Why is the operation address incremented by two?

    - by Gavin Jones
    I am looking at a Javascript emulator of a NES to try and understand how it works. On this line: addr = this.load(opaddr+2); The opcode is incremented by two. However, the documentation (see appendix E) I'm reading says: Zero page addressing uses a single operand which serves as a pointer to an address in zero page ($0000-$00FF) where the data to be operated on can be found. By using zero page addressing, only one byte is needed for the operand, so the instruction is shorter and, therefore, faster to execute than with addressing modes which take two operands. An example of a zero page instruction is AND $12. So if the operand's argument is only one byte, shouldn't it appear directly after it, and be + 1 instead of + 2? Why +2? This is how I think it works, which may be incorrect. Suppose our memory looks like: ------------------------- | 0 | 1 | 2 | 3 | 4 | 5 | <- index ------------------------- | a | b | c | d | e | f | <- memory ------------------------- ^ \ PC and our PC is 0, pointing to a. For this cycle, we say that the opcode: var pc= 0; //for example's sake var opcode= memory[pc]; //a So shouldn't the first operand be the next slot, i.e. b? var first_operand = memory[pc + 1]; //b

  • Bridged virtual interface is not available or visible to ifconfig.

    - by Omniwombat
    Hello all. I'm running Ubuntu 9.04, kernel 2.6.28-18, and vmware-server 2.0.1. I'm attempting to setup a virtual linux machine to use a bridged interface rather than NAT or host-only. Both NAT and host-only work just fine. When running vmware-config.pl, I set /dev/vmnet0 to bridge eth0, /dev/vmnet1 to host-only, and /dev/vmnet8 to NAT. When I run ifconfig -a I see the physical interface (eth0), vmnet1 and vmnet8 both of which are up and have IP addresses assigned to them. I also see other various interfaces that are not relevant here. In the web console, when I ask that the guest machine's network card be bridged, it states that a bridged setup is "Not available" and shows the disabled device icon. Inside the guest machine, I do have an eth0 interface which I can set to anything I like, however it can't see my external network, or the host. I do see errors in my vmware/hostd.log which state: "The network bridge on device vmnet0 is not running. The virtual machine will not be able to communicate with the host or with other machines on your network" which confirms the problem. vmnet-bridge is running, and I see the following in my process table: /usr/bin/vmnet-bridge -d /var/run/vmnet-bridge-0.pid -n 0 -i eth0 I confirm that the /var/run/vmnet-bridge-0.pid file is there and that it points to the correct process. I saw this question relating to Ubuntu 9.04 and bridged interfaces, in which the poster determined that the vsock library was not getting built due to a flaw in the vmware-config.pl script. I applied the patch, reran the script, and confirm that vsock.ko and vsock.o are in my /lib directory structure. vsock does show up in an lsmod. My /etc/vmware directory has /vmnet1 and /vmnet8 subdirectories. They contain configuration utilities for running DHCP and nat type services as expected. There is no vmnet0 subdirectory. My /etc/vmware/netmap.conf file DOES show entries for vmnet0; both the name and the device as I configured it from the script. My /dev directory contains devices vmnet0 through vmnet9. They have major device number 119, and minor device numbers 0 through 9. /proc/net/dev shows statistics for vmnet1 and vmnet8, but not vmnet0. I have a /proc/vmnet directory, but it's empty. When I start or stop the vmware service with /etc/init.d/vmware start, I see the following: Starting VMware services: Virtual machine monitor done Virtual machine communication interface done VM communication interface socket family: done Virtual ethernet done Bridged networking on /dev/vmnet0 done Host-only networking on /dev/vmnet1 (background) done DHCP server on /dev/vmnet1 done Host-only networking on /dev/vmnet8 (background) done DHCP server on /dev/vmnet8 done NAT service on /dev/vmnet8 done VMware Server Authentication Daemon (background) done Shared Memory Available done Starting VMware management services: VMware Server Host Agent (background) done VMware Virtual Infrastructure Web Access Starting VMware autostart virtual machines: Virtual machines done Nothing appears to be wrong there. What n00b thing am I doing such that vmnet0 and only vmnet0 does not show up in the interface list?

  • Connected host failed to respond (internal NAT address)

    - by MostRandom
    I'm writing my first C# web application that connects to an XML based service. It requires that I present a certificate and feed the XML stream. It seems to authenticate properly but then it gives the following error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.1.10.4:3128 The funny thing is that I'm not on a proxy or anything like that. I'm connecting directly to the internet. At one point I we did use a proxy that with internal NAT address. So my question is: Does Visual Studio have some sort of default proxy setting that I need to change? This IP is no longer used for anything, so I know that I don't need to use any proxy authentication code. using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Net; using System.Security.Cryptography.X509Certificates; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; namespace WebApplication1 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Uri requestURI = new Uri("*site omitted*"); //Create the Request Object HttpWebRequest pageRequest = (HttpWebRequest)WebRequest.Create(requestURI); //After installing the cert on the server export a client cert to the working directory as Deluxe.cer string certFile = "*certificate omitted*"; X509Certificate cert = X509Certificate.CreateFromCertFile(certFile); //Pull in your Data, if it is from an external xml as below or create an xml string with variables if a dynamic post is required. string xmlPath = "*XML omitted*"; System.Xml.XmlDocument passXML = new System.Xml.XmlDocument(); passXML.Load(xmlPath); //XML String with the data needed to pass string postData = passXML.OuterXml; //Set the Request Object parameters pageRequest.ContentType = "application/x-www-form-urlencoded"; pageRequest.Method = "POST"; pageRequest.AllowWriteStreamBuffering = false; pageRequest.AllowAutoRedirect = false; pageRequest.ClientCertificates.Add(cert); postData = "xml_data=" + Server.UrlEncode(postData); pageRequest.ContentLength = postData.Length; //Create the Post Stream Object System.IO.StreamWriter postStream = new System.IO.StreamWriter(pageRequest.GetRequestStream()); //Write the data to the post stream postStream.Write(postData); postStream.Flush(); postStream.Close(); //Set the Response Object HttpWebResponse postResponse = (HttpWebResponse)pageRequest.GetResponse();

  • How can I host a website on a dynamically-assigned IP address?

    - by nick
    I recently upgraded my internet to the point that it is much faster and more reliable than my current webhost. I would like to move my current domain to be hosted at home, but my IP address is dynamic. As far as I know, I only get a new IP when I restart my modem and or router (which is almost never) or when cable one (my ISP) pushes out a firmware update (rarely). There are a few ways I can see doing this: Convince my ISP to give me a static IP Assign my router my current IP to force a static IP (which might work?) Set my DNS record to my current IP address and update it on the rare occasions that it changes. Obviously I'm hoping that the first one works, but I don't want to pay a lot of extra money (if that's what it takes) to get a static IP address. Which of these options will work most reliably?

  • How to clear a Firefox address bar without selecting its content?

    - by zuba
    Sometimes I need to move an url from an app to a browser. I select the url, say in gvim, and make Firefox window active. Then I see that I should clear address bar before pasting the new url, which requires selecting existing url, which wipes the new url from PRIMARY clipboard out. What is the best way to put the new url from PRIMARY clipboard to address bar? Is there a shortcut to clear address bar and then to move focus there? ps I know I can use Ctrl-C to put the new url to CLIPBOARD clipboard, but I prefer to use PRIMARY clipboard.

  • How to be anonymous on IPV6 protocol by not using MAC address in EUI-64?

    - by iugamarian
    The IPV6 protocol has a feature called "Extended Unique Identifier" or EUI-64 witch in short uses the MAC address of the network card when choosing an IPV6 Adress. Proof: http://www.youtube.com/watch?v=30CnqRK0GHE&NR=1 at 7:36 video time. If you want to be anonymous on the internet (so that nobody can find you when you download something, etc.) you need this EUI-64 to be bipassed in order for the MAC address not to be discovered by harmful third parties on the internet and for privacy. How do you avoid EUI-64 MAC address usage in IPV6 selection in Ubuntu? Also for DHCP IPV6?

  • How to write the path to a Windows shared folders address in terminal?

    - by user206996
    I want to permanently mount a few Windows shared folders. I googled that topic and found a lot of good answers, but with all the solutions I have a little problem: I believe I can't properly give an address of shared folder. I can find it following way: "Network" - "Windows Network" - "WORKGROUP_name" - "Computer_name" - and there is some folder i would like to mount. How can I write the path to the folders in terminal? UPD i can access needed folder throw address in location bar smb://server/ro/, but i try mount it by editing /etc/fstab file (using guide https://wiki.ubuntu.com/MountWindowsSharesPermanently) i get error mount error: could not resolve address for server: Unknown error PS in /etc/fstab : //SERVER/RO /media/server cifs username=user,password=pwd, uid=1000,iocharset=utf8 0 0

  • Reading email address from contacts fails with weird memory issue - Solved

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount > 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on? Solution: It turned out that I wasn't storing the ABRecordRef personDealingWith var correctly. I'm still not sure how to do that properly, but instead of having the functionality in another routine (performed later), I'm now doing the grunt-work in the delegate method, and using the derived results at my leisure. The new (working) routine: - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person { // as soon as they select someone, return personDealingWithFullName = (NSString *)ABRecordCopyCompositeName(person); personDealingWithFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); // construct array of emails [personDealingWithEmails removeAllObjects]; ABMutableMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty); if (ABMultiValueGetCount(multi) > 0) { // collect all emails in array for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [personDealingWithEmails addObject:(NSString *)emailRef]; CFRelease(emailRef); } } CFRelease(multi); return NO; }

  • IP address shows as a hyphen for failed remote desktop connections in Event Log

  • Automapper: Handling NULL members

    - by PSteele
    A question about null members came up on the Automapper mailing list.  While the problem wasn’t with Automapper, investigating the issue led to an interesting feature in Automapper. Normally, Automapper ignores null members.  After all, what is there really to do?  Imagine these source classes: public class Source { public int Data { get; set; } public Address Address { get; set; } }   public class Destination { public string Data { get; set; } public Address Address { get; set; } }   public class Address { public string AddressType { get; set; } public string Location { get; set; } } And imagine a simple mapping example with these classes: Mapper.CreateMap<Source, Destination>();   var source = new Source { Data = 22, Address = new Address { AddressType = "Home", Location = "Michigan", }, };   var dest = Mapper.Map<Source, Destination>(source); The variable ‘dest’ would have a complete mapping of the Data member and the Address member. But what if the source had no address? Mapper.CreateMap<Source, Destination>();   var source = new Source { Data = 22, };   var dest = Mapper.Map<Source, Destination>(source); In that case, Automapper would just leave the Destination.Address member null as well.  But what if we always wanted an Address defined – even if it’s just got some default data?  Use the “NullSubstitute” option: Mapper.CreateMap<Source, Destination>() .ForMember(d => d.Address, o => o.NullSubstitute(new Address { AddressType = "Unknown", Location = "Unknown", }));   var source = new Source { Data = 22, };   var dest = Mapper.Map<Source, Destination>(source); Now, the ‘dest’ variable will have an Address defined with a type and location of “Unknown”.  Very handy!

  • Setting up Mono/ASP.NET 4.0 on Apache2/Ubuntu: Virtual hosts?

    - by Dave
    I'm attempting to setup Mono/ASP.NET 4.0 on my Apache server (which is running on Ubuntu). Thus far, I've been following a few tutorials/scripts supplied here, and here. As of now: Apache 2.2 is installed (accessible via 'localhost') Mono 2.10.5 is installed However, I'm struggling to configure Apache correctly... apparently the Virtual Host setting isn't doing its job and invoking the mod_mono plugin, nor is it even pulling source from the proper directory. While the Virtual Host setting points to '\srv\www\localhost', it clearly is pulling content instead from 'var/www/', which I've found is the default DocumentRoot for virtual hosts. I can confirm: "/opt/mono-2.10/bin/mod-mono-server4" exists. Virtual hosts file is being read, since undoing the comment in the main httpd.conf changed the root directory from 'htdocs' to 'var/www/' The Mono installation is at least semi-capable of running ASP 4.0, as evidenced by running XSP, navigating to 0.0.0.0:8080/ and getting an ASP.NET style error page with "Mono ASP 4.0.x" at the bottom. Can anyone point out how to fix these configurations and get Mono linked up with Apache? Here are my configs and relevant information: /usr/local/apache2/conf/httpd.conf: # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo_log" # with ServerRoot set to "/usr/local/apache2" will be interpreted by the # server as "/usr/local/apache2/logs/foo_log". # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "/usr/local/apache2" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default.

  • Fix: Azure Disabled over 49 cents? Beware of using a Java Virtual Machine on Microsoft Azure

    - by Ken Cox [MVP]
    I love my MSDN Azure account. I can spin up a demo/dev app or VM in seconds. In fact, it is so easy to create a virtual machine that Azure shut down my whole account! Last night I spun up a Java Virtual Machine to play with some Android stuff. My mistake was that I didn’t read the Virtual Machine pricing warning: “I have a MSDN Azure Benefit subscription. Can I use my monthly Azure credits to purchase Oracle software?” “No, Azure credits in our MSDN offers are not applicable to Oracle software. In order to purchase Oracle software in the MSDN Azure Benefit subscription, customers need to turn off their {0} spending limit and pay at the regular pay-as-you-go rate. Otherwise, Oracle usage will hit the {1} spending limit and the subscription will be immediately disabled.”  Immediately disabled? Yup. Everything connected to the subscription was shut off, deallocated, rendered useless - even the free Web sites and the free Sendgrid email service.  The fix? I had to remove the spending limit from my account so I could pay $0.49 (49 cents) for the JVM usage. I still had $134.10 in credits remaining for regular usage with 6 days left in the billing month.  Now the restoration/clean-up begins… figuring out how to get the web sites and services back online.  To me, the preferable way would be for Azure to warn me when setting up a JVM that I had no way of paying for the service. In the alternative, shut down just the offending services – the ones that can’t be covered by the regular credits. What a mess.

  • OpenGL Colorspace Conversion

    - by Steven Behnke
    Does anyone know how to create a texture with a YUV colorspace so that we can get hardware based YUV to RGB colorspace conversion without having to use a fragment shader? I'm using an NVidia 9400 and I don't see an obvious GL extension that seems to do the trick. I've found examples how to use a fragment shader, but the project I'm working on currently only supports OpenGL 1.1 and I don't have time to convert it to 2.0 and perform all the regression testing necessary. This is also targeting Linux. On other platforms I've been using a MESA extension but it doesn't function on the Nvidia card.

  • Running cmd commands via .NET?

    - by a2h
    System.Diagnostics.Process proc0 = new System.Diagnostics.Process(); proc0.StartInfo.FileName = "cmd"; proc0.StartInfo.WorkingDirectory = Path.Combine(curpath, "snd"); proc0.StartInfo.Arguments = omgwut; And now for some background... string curpath = System.IO.Path.GetDirectoryName(Application.ExecutablePath); omgwut is something like this: copy /b t.wav + y.wav + p.wav + e.wav + space.wav + i.wav + n.wav + space.wav + s.wav + o.wav + m.wav + e.wav + space.wav + t.wav + e.wav + x.wav + t.wav + space.wav + h.wav + e.wav + r.wav + e.wav + space.wav + a.wav + n.wav + d.wav + space.wav + p.wav + y.wav + r.wav + o.wav + space.wav + w.wav + i.wav + l.wav + l.wav + space.wav + s.wav + h.wav + o.wav + w.wav + space.wav + h.wav + i.wav + s.wav + space.wav + r.wav + e.wav + n.wav + d.wav + i.wav + t.wav + o.wav + n.wav + space.wav output.wav And nothing happens at all. So obviously something's wrong. I also tried "copy" as the executable, but that doesn't work.

  • Algorithm to generate numerical concept hierarchy

    - by Christophe Herreman
    I have a couple of numerical datasets that I need to create a concept hierarchy for. For now, I have been doing this manually by observing the data (and a corresponding linechart). Based on my intuition, I created some acceptable hierarchies. This seems like a task that can be automated. Does anyone know if there is an algorithm to generate a concept hierarchy for numerical data? To give an example, I have the following dataset: Bangladesh 521 Brazil 8295 Burma 446 China 3259 Congo 2952 Egypt 2162 Ethiopia 333 France 46037 Germany 44729 India 1017 Indonesia 2239 Iran 4600 Italy 38996 Japan 38457 Mexico 10200 Nigeria 1401 Pakistan 1022 Philippines 1845 Russia 11807 South Africa 5685 Thailand 4116 Turkey 10479 UK 43734 US 47440 Vietnam 1042 for which I created the following hierarchy: LOWEST ( < 1000) LOW (1000 - 2500) MEDIUM (2501 - 7500) HIGH (7501 - 30000) HIGHEST ( 30000)
