  • C++ stack for multiple data types (RPN vector calculator)

    - by Arrieta
    Hello: I have designed a quick and basic vector arithmetic library in C++. I call the program from the command line when I need a rapid cross product, or angle between vectors. I don't use Matlab or Octave or related, because the startup time is larger than the computation time. Again, this is for very basic operations. I am extending this program, and I will make it work as an RPN calculator, for operations of the type: 1 2 3 4 5 6 x out: -3 6 -3 (give one vector, another vector, and the "cross" operator; spit out the cross product) The stack must accept 3d vectors or scalars, for operations like: 1 2 3 2 * out: 2 4 6 The lexer and parser for this mini-calculator are trivial, but I cannot seem to think of a good way for creating the internal stack. How would you create a stack of for containing vectors or doubles (I rolled up my own very simple vector class - less than one hundred lines and it does everything I need). How can I create a simple stack which accepts elements of class Vector or type double? Thank you.

  • Linked Measure Groups and Local Dimensions

    - by ekoner
    Mulling over something I've been reading up on. According to Chris Webb, A linked measure group can only be used with dimensions from the same database as the source measure group. So I took this to mean as long as two cubes share a database, a linked measure group can be used with a dimension. So I created a new cube and added a local measure group, a local dimension and a linked measure group. However, I can't create a relationship between the linked measure group and the local dimension even though they are within the same database. I get the message below: Regular relationships in the current database between non-linked (local) dimensions and linked measure groups cannot be edited. These relationship can only be created through the wizard. This dialog can be used to delete these relationships. I see that I can go to the original cube and add the dimension there, but does the message below mean I have an alternative? I just know it's going to be something simple and trivial! Thanks for reading.

  • How to send large objects using boost::asio

    - by Max
    Good day. I'm receiving a large objects via the net using boost::asio. And I have a code: for (int i = 1; i <= num_packets; i++) boost::asio::async_read(socket_, boost::asio::buffer(Obj + packet_size * (i - 1), packet_size), boost::bind(...)); Where My_Class * Obj. I'm in doubt if that approach possible (because i have a pointer to an object here)? Or how it would be better to receive this object using packets of fixed size in bytes? Thanks in advance.

  • news feed using .Net Dataservices / OData / Atom ?

    - by Stephan
    Let's say I have an web CMS type application, and an EDM model with an entity called 'article', and I need to offer the ability for client applications, to a read/query the articles (and other resources stored in our database) a straightforward syndication feed of these articles to end users (along the lines of a simple RSS feed) It seems to me that for the first task, and .net 4's dataservice would be perfect for the job. For the second case, I'm wondering (a) whether atom the right format to choose - I think it is - and (b) whether it's possible to achieve such a feed using the same ado.net OData service. I took a look at some of the examples out there and briefly set up a proof of concept: http://localhost/projectname/DataService.svc/Articles <?xml version="1.0" encoding="utf-8" standalone="yes"?> <feed xml:base="http://localhost/projectname/DataService.svc/" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom"> <title type="text">Articles</title> <id>http://localhost/projectname/DataService.svc/Articles</id> <updated>2010-05-21T09:41:22Z</updated> <link rel="self" title="Articles" href="Articles" /> <entry> <id>http://---------DataService.svc/Articles(1)</id> <title type="text"></title> <updated>2010-05-21T09:41:22Z</updated> <author> <name /> </author> <link rel="edit" title="Article" href="Articles(1)" /> <category term="Model1.Article" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /> <content type="application/xml"> <m:properties> <d:int_ContentID m:type="Edm.Int32">1</d:int_ContentID> <d:Titel>hello world</d:Titel> <d:Source>http://www.google.com</d:Source> </m:properties> </content> </entry> </feed> and noticed that, though the feed works and items are showing up, the title tag on the entry level is left blank. (as a result, when you check this feed in a feed reader, you will see no title). I searched msdn but haven't found a way to do that, but it should be possible. Stackoverflow itself uses an atom feed in that fashion, so it should be possible. Right? So I suppose my question is; Is there a way to make the ado.net dataservice Atom feed look like something suitable for your average news feed reader? - OR, am I using the wrong tool for the wrong purposes, and should I be looking elsewhere (.net syndication API's perhaps)?

  • How to perform undirected graph processing from SQL data

    - by recipriversexclusion
    I ran into the following problem in dynamically creating topics for our ActiveMQ system: I have a number of processes (M_1, ..., M_n), where n is not large, typically 5-10. Some of the processes will listen to the output of others, through a message queue; these edges are specified in an XML file, e.g. <link from="M1" to="M3"</link> <link from="M2" to="M4"</link> <link from="M3" to="M4"</link> etc. The edges are sparse, so there won't be many of them. I will parse this XML and store this information in an SQL DB, one table for nodes and another for edges. Now, I need to dynamically create strings of the form M1.exe --output_topic=T1 M2.exe --output_topic=T2 M3.exe --input_topic=T1 --output_topic=T3 M4.exe --input_topic=T2 --input_topic=T3 where the tags are sequentially generated. What is the best way to go about querying SQL to obtain these relationships? Are there any tools or other tutorials you can point me to? I've never done graps with SQL. Using SQL is imperative, because we use it for other stuff, too. Thanks!

  • Data mining - parsing a log file in Java

    - by nuvio
    Hello I am carrying on a Java project for the university, where I should analyse poker hands. I found some poker hands in a txt log file. They would typically look like this: PokerStars Zoom Hand #86981279921: Hold'em No Limit ($0.10/$0.25 USD) - 2012/09/30 23:49:51 ET Table 'Whirlpool Zoom 40-100 bb' 9-max Seat #1 is the button Seat 1: lgwong ($30.99 in chips) Seat 2: hastyboots ($28.61 in chips) Seat 3: seula i ($25.31 in chips) Seat 4: fr_kevin01 ($31.81 in chips) Seat 5: limey05 ($27.45 in chips) Seat 6: sanlu ($24.65 in chips) Seat 7: Masterfrank ($25.35 in chips) Seat 8: Refu$e2Lose ($33.23 in chips) Seat 9: 1pepepe0114 ($37.62 in chips) hastyboots: posts small blind $0.10 seula i: posts big blind $0.25 *** HOLE CARDS *** fr_kevin01: folds limey05: folds sanlu: folds Masterfrank: folds Refu$e2Lose: folds 1pepepe0114: folds lgwong: folds hastyboots: folds Uncalled bet ($0.15) returned to seula i seula i collected $0.20 from pot seula i: doesn't show hand *** SUMMARY *** Total pot $0.20 | Rake $0 Seat 1: lgwong (button) folded before Flop (didn't bet) Seat 2: hastyboots (small blind) folded before Flop Seat 3: seula i (big blind) collected ($0.20) Seat 4: fr_kevin01 folded before Flop (didn't bet) Seat 5: limey05 folded before Flop (didn't bet) Seat 6: sanlu folded before Flop (didn't bet) Seat 7: Masterfrank folded before Flop (didn't bet) Seat 8: Refu$e2Lose folded before Flop (didn't bet) Seat 9: 1pepepe0114 folded before Flop (didn't bet) My problem is that I am not sure about how to proceed to parse the log file: the only knowledge I have is "manually" scanning line by line for a particular character or symbol, but I am afraid it would need exhaustive error handling. So I was wandering if there is any other techniques or better way to parse these poker hands? Many thanks for your help

  • arbitrary typed data in django model

    - by Dmitry Shevchenko
    I have a model, say, Item. I want to store arbitrary amount of attributes on it, like title, description, release_date. And i want them to be not just strings but have python type, so string, boolean, datetime etc. What are my options here? EAV pattern with separate name-value table won't work because of the same DB type across all values. JSONField can probably help, but it doesn't know about datetime, for example. Also i was looking at PickeField, it fits perfectly, but i'm a bit concerned about performance.

  • Easiest Way to Parse data from twitter with Coccoa

    - by happyCoding25
    Hello, Im followed the tutorial from here: Twitter Client Tutorial to make a little twitter app. Now I need to find out how to parse the XML twitter gives you when you make a request. I've looked at tons of tutorials on phrasing xml on the iPhone but none have made much sense because Im still new to cocoa. Twitter stores the text of the tweet in something like this <text> Some tweet here </text>. From reading the tutorials I think this would involve nsxmlparser but I'm not sure. If anyone could share some code that could parse the <text> Some tweet here </text> things into an array that would be really great. Thanks in advance

  • NSMutableObject from existing custom class

    - by A.S.
    Hello there. I have an existing class that has methods to deserialise from XML in my code. Now I need to create correct CoreData model from that class. It's objects will be created not only from CoreData storage but also by deserializing XML (somehow like instance->title = [[NSString stringWithUTF8String: (const char *)subNode->children->content] retain; ) without saving to CoreData, and sometimes I need to save it. What is the correct steps to modify existing class to do that except of adding CoreData framework and making my class an NSManagedObject instead of NSObject? Class sample: @interface TSTSong : NSManagedObject<NTSerializableObject> { NSString *identifier; NSString *title; float length; NSURL *previewURL; NSString *author; NSURL *coverURL; NSString *appStoreId; BOOL isPurchased; NSURL *bannerURL; NSDecimalNumber *priceValue; NSLocale *priceLocale; } P.S. I'm noob, so I'f I'm doing smth. wrong - please let me know. Sorry for my english.

  • Discover periodic patterns in a large data-set

    - by Miner
    I have a large sequence of tuples on disk in the form (t1, k1) (t2, k2) ... (tn, kn) ti is a monotonically increasing timestamp and ki is a key (assume a fixed length string if needed). Neither ti nor ki are guaranteed to be unique. However, the number of unique tis and kis is huge (millions). n itself is very large (100 Million+) and the size of k (approx 500 bytes) makes it impossible to store everything in memory. I would like to find out periodic occurrences of keys in this sequence. For example, if I have the sequence (1, a) (2, b) (3, c) (4, b) (5, a) (6, b) (7, d) (8, b) (9, a) (10, b) The algorithm should emit (a, 4) and (b, 2). That is a occurs with a period of 4 and b occurs with a period of 2. If I build a hash of all keys and store the average of the difference between consecutive timestamps of each key and a std deviation of the same, I might be able to make a pass, and report only the ones that have an acceptable std deviation(ideally, 0). However, it requires one bucket per unique key, whereas in practice, I might have very few really periodic patterns. Any better ways?

  • Should an NSLock instance be "global"?

    - by Alex Reynolds
    Should I make a single NSLock instance in the application delegate, to be used by all classes? Or is it advisable to have each class instantiate its own NSLock instance as needed? Would the locking work in the second case, if I, for example, had access to a managed object context that is spread across two view controllers?

  • Using Linq2Sql to insert data into multiple tables using an auto incremented primary key

    - by Thomas
    I have a Customer table with a Primary key (int auto increment) and an Address table with a foreign key to the Customer table. I am trying to insert both rows into the database in one nice transaction. using (DatabaseDataContext db = new DatabaseDataContext()) { Customer newCustomer = new Customer() { Email = customer.Email }; Address b = new Address() { CustomerID = newCustomer.CustomerID, Address1 = billingAddress.Address1 }; db.Customers.InsertOnSubmit(newCustomer); db.Addresses.InsertOnSubmit(b); db.SubmitChanges(); } When I run this I was hoping that the Customer and Address table automatically had the correct keys in the database since the context knows this is an auto incremented key and will do two inserts with the right key in both tables. The only way I can get this to work would be to do SubmitChanges() on the Customer object first then create the address and do SubmitChanges() on that as well. This would create two roundtrips to the database and I would like to see if I can do this in one transaction. Is it possible? Thanks

  • C# thread functions not properly sharing a static data member

Problem: Datatable ScheduleConfiguration is updated in the UpdateSchedulingRefTable (called from outside world - say manually) but when i try to use Datatable ScheduleConfiguration in GetAndSaveScheduledUpdate, i get the older version of values.... What am I missing in this stuff??? About EDIT: I thought the stuff i have not shown is quite obvious and possibly not desired, perhaps my structure is wrong :) and sorry for incorrect code previously, i made a simple function call as a thread initialization... sorry for my code indentation too because i don't know how to format whole block...

  • Display additional data while iterating over a Django formset

The list comes from a remote source. matches = ["A vs. B", "C vs. D", "E vs, F"] matchFormset = formset_factory(MatchForm,extra=len(matches)) formset = MatchFormset() On the template side, I would like to display the formset with the according title (i.e. "A vs. B"). {% for form in formset.forms %} <fieldset> <legend>{{TITLE}}</legend> {{form.team1}} : {{form.team2}} </fieldset> {% endfor %} Now how do I get TITLE to contain the right title for the current form? Or asked in a different way: how do I iterate over matches with the same index as the iteration over formset.forms? Thanks for your input!

  • HT create a new vector in data frame that takes correlation of existing vectors

    - by Milktrader
    I have a time series of two indexes, with each row representing the closing price on the same day. I'd like to go to row 30 and lookback over the last 30 'days' and calculate the pearson correlation. And then store that value in a new vector. Then, repeat the calculation for the entire time series. It is a trivial task in Excel, so I'm convinced it can be done in R. I don't know the method to use though.

  • Visual Studio ReportViewer repeating data block on every page

    - by muhan
    I am using Reportviewer to generate a sales invoice to be printed by the user. How can I get databound fields to be printed on every page of a multi page invoice? The invoice is printed on a pre-printed form. I want the printed form to look roughly like: page 1 customer john smith 123 main st. city, CA 90000 some item1 $100 some item2 $150 some item3 $150 page 2 customer john smith 123 main st. city, CA 90000 some item4 $500 some item5 $250 some item6 $950 Total $2100 Using 1 list which contains databound textbox fields for the customer info, and a table for the items. The problem is if there are many items such that the items flow over to page 2, the next page only contains items, and not the customer info which needs to be printed on second page as well. I tried using page header, but I can't use databound items in page header. Please Help!
