  - by Buffernet

  I'm in xcode debugging my iphone application. when i get to a break point and I roll over my object and properties of that object say "out of scope" instead of their respective values.

• Result in an argument isn't correct

  - by Paulo Nunes

  So I have this piece of prolog code: my_avalia(A,R) :- A=="Koza" -koza(R,0,0,e,89). koza(R,_,_,_,87):-!,write(R). koza(R,X,Y,V,C):-movex(V,X,X1),movey(V,Y,Y1),confirma(X1,Y1,Z),Z==1->(append(R,[emFrente],U),L is (C-1),koza(U,X1,Y1,V,L)). The matter is that when I write the "R" at koza(), it has the correct values, however it ends up with a empty list in my_avalia when I call it like this: my_avalia("Koza",R). My recursion might be incorrect but I don't really know what's wrong with it. Thanks in advance.

• How to get Netty websocket client example working

  - by Paul Butcher

  I'm struggling to get the netty example websocket client working. I've compiled successfully with 4.0.0.Alpha8, but when I try to connect to a server (also a netty example) I get: Exception in thread "main" io.netty.handler.codec.http.websocketx.WebSocketHandshakeException: Invalid handshake response upgrade: websocket at io.netty.handler.codec.http.websocketx.WebSocketClientHandshaker13.finishHandshake(WebSocketClientHandshaker13.java:204) which makes no sense to me whatsoever, given that this piece of code reads: String upgrade = response.getHeader(Names.UPGRADE); if (!Values.WEBSOCKET.equalsIgnoreCase(upgrade)) { throw new WebSocketHandshakeException("Invalid handshake response upgrade: " + response.getHeader(Names.UPGRADE)); } And as the message in the exception demonstrates, the Upgrade header does contain websocket as expected. Any idea what's going on?

• pythonic way to associate list elements with their indices

  - by Dragan Chupacabrovic

  Hello Everybody, I have a list of values and I want to put them in a dictionary that would map each value to it's index. I can do it this way: >>> t = (5,6,7) >>> d = dict(zip(t, range(len(t)))) >>> d {5: 0, 6: 1, 7: 2} this is not bad, but I'm looking for something more elegant. I've come across the following, but it does the opposite of what I need: >>> d = dict(enumerate(t)) >>> d {0: 5, 1: 6, 2: 7} Please share your solutions, Thank you

• Using numeric_limits::max() in constant expressions

  - by FireAphis

  Hello, I would like to define inside a class a constant which value is the maximum possible int. Something like this: class A { ... static const int ERROR_VALUE = std::numeric_limits<int>::max(); ... } This declaration fails to compile with the following message: numeric.cpp:8: error: 'std::numeric_limits::max()' cannot appear in a constant-expression numeric.cpp:8: error: a function call cannot appear in a constant-expression I understand why this doesn't work, but two things look weird to me: It seems to me a natural decision to use the value in constant expressions. Why did the language designers decide to make max() a function thus not allowing this usage? The spec claims in 18.2.1 that For all members declared static const in the numeric_limits template, specializations shall define these values in such a way that they are usable as integral constant expressions. Doesn't it mean that I should be able to use it in my scenario and doesn't it contradict the error message? Thank you.

• Annotate and Aggregate function in django

  - by thesteve

  In django I have the following tables and am trying to count the number of votes by item. class Votes(models.Model): user = models.ForeignKey(User) item = models.ForeignKey(Item) class Item(models.Model): name = models.CharField() description = models.TextField() I have the following queryset queryset = Votes.objects.values('item__name').annotate(Count('item')) that returns a list with item name and view count but not the item object. How can I set it up so that the object is returned instead of just the string value? I have been messing around with Manager and Queryset methods, that the right track? Any advice would be appreciated.

• How to format a money value from an ISOCurrencySymbol in C#

  - by nareshbhatia

  I have created a Money class to save money values in different currencies. The class uses 3 letter ISO symbols to store currency types: public class Money { public decimal Amount { get; set; } public string Currency { get; set; } } Is there a way in C# to use this information, say 100.00 USD, and format it as "$100.00"? Only way I know of requires CultureInfo like this: Amount.ToString("C", CultureInfo.CreateSpecificCulture("en-US")); However this does not work with my Money class. Is there another solution? I am open to changing my Money class. I have searched this site for similar questions (such as this), but couldn't find one that answers the above question.

• Neural Network problems

  - by Betamoo

  I am using an external library for Artificial Neural Networks in my project.. While testing the ANN, It gave me output of all NaN (not a number in C#) The ANN has 8 input , 5 hidden , 5 hidden , 2 output, and all activation layers are of Linear type , and it uses back-propagation, with learning rate 0.65 I used one testcase for training { -2.2, 1.3, 0.4, 0.5, 0.1, 5, 3, -5 } ,{ -0.3, 0.2 } for 1000 epoch And I tested it on { 0.2, -0.2, 5.3, 0.4, 0.5, 0, 35, 0.0 } which gave { NaN , NaN} Note: this is one example of many that produces same case... I am trying to discover whether it is a bug in the library, or an illogical configuration.. The reasons I could think of for illogical configuration: All layers should not be linear Can not have descending size layers, i.e 8-5-5-2 is bad.. Only one testcase ? Values must be in range [0,1] or [-1,1] Is any of the above reasons could be the cause of error, or there are some constraints/rules that I do not know in ANN designing..? Note: I am newbie in ANN

• assigning in system of differential equations

  - by Alireza

  hi every one! when i solve numerically a system of two differential equations: s1:=diff(nDi, t)=...; s2:=diff(nT, t)=...; ics:={...}; #initial condition. sys := {s1, s2, ics}: sol:=dsolve(sys,numeric); with respect to "t",then the solution (for example)for "t=4" is of the form, sol(4): [t=4, n1(t)=const1, n2(t)=const2]. now, how is possible to use values of n1(t) and n2(t) for all "t"'s in another equation, namely "p", which involved n1(t) or n2(t)(like: {p=a+n1(t)*n2(t)+f(t)},where "a" and "f(t)" are defined), and to plot "p" for an interval of "t"?

• How to leverage concurrency checking with EF 4.0 POCO Self Tracking Entities in a N-Tier scenario?

  - by Mark Lindell

  I'm using VS1010RC with the POCO self tracking T4 templates. In my WCF update service method I am using something similar to the following: using (var context = new MyContext()) { context.MyObjects.ApplyChanges(myObject); context.SaveChanges(); } This works fine until I set ConcurrencyMode=Fixed on the entity and then I get an exception. It appears as if the context does not know about the previous values as the SQL statement is using the changed entities value in the WHERE clause. What is the correct approach when using ConcurrencyMode=Fixed?

• plotting results of hierarchical clustering ontop of a matrix of data in python

  - by user248237

  How can I plot a dendrogram right on top of a matrix of values, reordered appropriately to reflect the clustering, in Python? An example is in the bottom of the following figure: http://www.coriell.org/images/microarray.gif I use scipy.cluster.dendrogram to make my dendrogram and perform hierarchical clustering on a matrix of data. How can I then plot the data as a matrix where the rows have been reordered to reflect a clustering induced by the cutting the dendrogram at a particular threshold, and have the dendrogram plotted alongside the matrix? I know how to plot the dendrogram in scipy, but not how to plot the intensity matrix of data with the right scale bar next to it. Any help on this would be greatly appreciated.

• Changing value of a Numeric Stepper

  - by REDDY

  Hi, I am a newbie to Flex and programming. I am trying something where I have 2 Numeric Steppers. One numeric stepper holds values from 0-230 and the other from 0.00-0.99. My question is how to change the value of the first numeric stepper when the second numeric stepper goes from 0.99 to 0.00. Suppose the first numeric stepper has a value 10 and the second numeric stepper is being incremented continuously. As it reaches 0.99 and on mouse up on the up arrow, 10 should change to 11 and this numeric stepper goes to 0.00. Could anyone help me out with some code or suggestion? Thanks is advance, REDDY

• A tool or framework extension or code snippet for logging the internal state of objects?

  - by George Mauer

  When spiking on how something works or when my unit test behave in an unpredictable manner I usually have to drop into debug mode. 99% of my time in debug mode is spent checking the values of fields on objects to verify its state. I already have log4net set up, it would seem that if I could easily add a line of code to log out the state of objects I could remove most of my need to start up the bulky debugger. The problem is of course that to expose object state implicitly you need to manually override each object's ToString() method. What I would like to be able to do is the ability to do logger.LogState(someObject) and have logged out the object state including at least a formatted list of all the private variables, references (to some arbitrary depth), and collections. Does anyone know a tool/framework/code snippet that can be used to generate a string of the internal state of any object? I could of course write one myself but its a non-trivial problem and I'd prefer something someone has put some thought into.

• Ho to get PHP setrawcookie value back?

  - by user250343

  The IETF recommends to use base64 encoding for binary cookie values. http://tools.ietf.org/html/draft-ietf-httpstate-cookie-07 So I use setrawcookie(..) but I don't know what variable to use to get the cookie back because $_COOKIE[..] still uses the URL decoding that matches setcookie(..). This replaces "+" with " " in the output. <?php var_dump($_COOKIE['TEST']); $binary_string = ""; for($index = 0; $index < 256; $index++){ $binary_string .= chr($index); } $encoded_data = base64_encode($binary_string); var_dump($encoded_data); $cookie_set = setrawcookie('TEST', $encoded_data, time() + 3600); ?

• How do I gain Control of a row in Tabular Layout in Oracle

  - by DotNetDan

  This might be simple but I am new to Oracle. I am using Oracle 10g and have a form that lists our information from a linked table in a tabular Layout. The last column of data is a "list Item" item type that has the Element list of Enabled (T) and Disabled (F). What I need is when a user changes this dropdown, to disabled, I want ONLY that row to have some of the columns be disabled and not the entire column. This is also assuming on load of the form, it will disable and enable rows of data depending on what values are being pulled from the EnabledDisabled column in the database. Thanks for the help!

• SQL Server 2008 Management Studio doesn't recognize new Schema

  - by Lieven Cardoen

  I have created a new Schema in a database called Contexts. Now when I want to write a query, Management Studio doesn't recognize the tables that belong to the new Schema. It says: 'Invalid object name Contexts.ContextLibraries'... Transact-SQL: INSERT INTO [Contexts].[ContextLibraries] (ChannelId, [IsSystem]) VALUES (@ChannelId, 1) When I try the same thing on my local database, it does work... Any ideas? I did try to change the Default schema for the user from dbo to Contexts but this doesn't work. Also checked Contexts in Schemas owned by this user without success. Update: Apparently the sql query does work but the editor gives a fault saying the object is invalid.

• Using boost unordered map

  - by Amrish

  Guys, I am using dynamic programming approach to solve a problem. Here is a brief overview of the approach Each value generated is identified using 25 unique keys. I use the boost::hash_combine to generate the seed for the hash table using these 25 keys. I store the values in a hash table declared as boost::unordered_map<Key_Object, Data_Object, HashFunction> hashState; I did a time profiling on my algorithm and found that nearly 95% of the run time is spent towards retrieving/inserting data into the hash table. These were the details of my hash table hashState.size() 1880 hashState.load_factor() 0.610588 hashState.bucket_count() 3079 hashState.max_size() 805306456 hashState.max_load_factor() 1 hashState.max_bucket_count() 805306457 I have the following two questions Is there anything which I can do to improve the performance of the Hash Table's insert/retrieve operations? C++ STL has hash_multimap which would also suit my requirement. How does boost libraries unordered_map compare with hash_multimap in terms of insert/retrieve performance.
