  • How to unit test django middleware?

    - by luc
    I've implemented a django middleware for getting pages from the database (something similar to the flatpage subframework) Unfortunately it seems that it is not possible to test it with the django testing framework. Any suggestion? Thanks in advance Update: maybe a mistake in my test but I can't get an object that should be returned by a middleware. I'll inverstigate more.

  • Variable-byte encoding clarification

    - by Myx
    Hello: I am very new to the world of byte encoding so please excuse me (and by all means, correct me) if I am using/expressing simple concepts in the wrong way. I am trying to understand variable-byte encoding. I have read the Wikipedia article (http://en.wikipedia.org/wiki/Variable-width_encoding) as well as a book chapter from an Information Retrieval textbook. I think I understand how to encode a decimal integer. For example, if I wanted to provide variable-byte encoding for the integer 60, I would have the following result: 1 0 1 1 1 1 0 0 (please let me know if the above is incorrect). If I understand the scheme, then I'm not completely sure how the information is compressed. Is it because usually we would use 32 bits to represent an integer, so that representing 60 would result in 1 1 1 1 0 0 preceded by 26 zeros, thus wasting that space as opposed to representing it with just 8 bits instead? Thank you in advance for the clarifications.

  • HG takes too much time to push

    - by phmr
    I commited a lot of files locally (including binary files removing & adding...) and now when I try to push it takes a lot of time. Actually I messed up my local repo history. How could I avoid this mistake in the future ? Can I transform a set of local revision 1-2-3-4 to 1-2 with 2 being the final revision of the local clone ?

  • Weird Java Math ,10 ^ 1 = 11?

    - by Simon
    For an exercise I was writing a loop that turns a string into an integer without using the built in functions by multiplying each individual value by its numerical position. 75 would be 7*(10 ^ 1) + 5*(10 ^ 0), for example. However, for some reason (10 ^ 1) keeps coming back as 11. Is there some mistake I have made or an explanation for this?

  • Is html5 video ready for primetime yet?

    - by Galen
    I've been asked to develop a website for the iPad. It's going to have a couple videos on it. I'd like to try out html5. I'd really only be using the new video part of html5 (with flash fallback for browsers that don't yet support it). Would it be a mistake to do this on a fairly traffic heavy site?

  • how to read values from the remote OPC Server

    - by Shailesh Jaiswal
    I have created one asp.net web service. In this web service I am using the web method as follows. The web service is related to the OPC ( OLE for process control) public string ReadServerItems(string ServerName) { string txt = ""; ArrayList obj = new ArrayList(); XmlServer Srv = new XmlServer("XDAGW.CS.WCF.Eval.1"); RequestOptions opt = new RequestOptions(); ReadRequestItemList iList = new ReadRequestItemList(); iList.Items = new ReadRequestItem[3]; iList.Items[0] = new ReadRequestItem(); iList.Items[0].ItemName = "ServerInfo.ConnectedClients"; iList.Items[1] = new ReadRequestItem(); iList.Items[1].ItemName = "ServerInfo.TotalGroups"; iList.Items[2] = new ReadRequestItem(); iList.Items[2].ItemName = "EventSources.Area1.Tracking"; ReplyItemList rslt; OPCError[] err; ReplyBase reply = Srv.Read(opt, iList, out rslt, out err); if ((rslt == null)) txt += err[0].Text; else { foreach (xmldanet.xmlda.ItemValue iv in rslt.Items) { txt += iv.ItemName; if (iv.ResultID == null) // success { txt += " = " + iv.Value.ToString() + "\r\n"; obj.Add(txt); } else txt += " : Error: " + iv.ResultID.Name + "\r\n"; } } return txt; } I am using the namespaces as follows using xmldanet; using xmldanet.xmlda; I have installed XMLDA.NET client component evaluation. In this there is an in built Test client which successfully reads the values of these data items from the remote OPC server. I also provides the template through which we can build the OPC based applications. In the above code I am trying to read the values of the data items but i am not able to read the values. I have applied the breakpoint. In that I can see that the condition if (iv.ResultID == null) becomes false & also there is null values in the variable rslt. Please tell me where I am doing mistake ? how should I correct my mistake ? can provide me the correct code ?

  • variables in assembler

    - by stupid_idiot
    hi, i know this is kinda retarded but I just can't figure it out. I'm debugging this: xor eax,eax mov ah,[var1] mov al,[var2] call addition stop: jmp stop var1: db 5 var2: db 6 addition: add ah,al ret the numbers that I find on addresses var1 and var2 are 0x0E and 0x07. I know it's not segmented, but that ain't reason for it to do such escapades, because the addition call works just fine. Could you please explain to me where is my mistake?

  • In MVVM should the ViewModel or Model implement INotifyPropertyChanged?

    - by Edward Tanguay
    Most MVVM examples I have worked through have had the Model implement INotifyPropertyChanged, but in Josh Smith's CommandSink example the ViewModel implements INotifyPropertyChanged. I'm still cognitively putting together the MVVM concepts, so I don't know if: you have to put the INotifyPropertyChanged in the ViewModel to get CommandSink to work this is just an aberration of the norm and it doesn't really matter you should always have the Model implement INotifyPropertyChanged and this is just a mistake which would be corrected if this were developed from a code example to an application What have been others' experiences on MVVM projects you have worked on?
