  • 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

  • Handling dynamic data from javascript or rails

    - by 99miles
    I have page consisting of a calendar view ( http://code.google.com/p/calendardateselect/ ) as well as divs, each of which contain information about a person. In each div I want to have a link to a new controller and action, and pass the id for the person and the date selected in the calendar. I can think of a one way, but I'm thinking there's likely a better solution: 1) Do something like: =link_to_function "Week", "weekClicked(#{person.id})" Then in the weekClicked() javascript method I get the selected date from the calendar, such as: $('e_date').selected_date; then with javascript I could make a post request as mentioned here: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit 2) Or, is there a way that I could make each link a button in it's own form and maybe have a hidden field that gets the selected date from the calendar as or before the form is submitted? I tried this too, but couldn't figure it out. This definitely seems like it's more on the right track than #1. Thanks.

  • Curve fitting: Find a CDF (or any function) that satisfies a list of constraints.

    - by dreeves
    I have some constraints on a CDF in the form of a list of x-values and for each x-value, a pair of y-values that the CDF must lie between. We can represent that as a list of {x,y1,y2} triples such as constraints = {{0, 0, 0}, {1, 0.00311936, 0.00416369}, {2, 0.0847077, 0.109064}, {3, 0.272142, 0.354692}, {4, 0.53198, 0.646113}, {5, 0.623413, 0.743102}, {6, 0.744714, 0.905966}} Graphically that looks like this: And since this is a CDF there's an additional implicit constraint of {Infinity, 1, 1} Ie, the function must never exceed 1. Also, it must be monotone. Now, without making any assumptions about its functional form, we want to find a curve that respects those constraints. For example: (I cheated to get that one: I actually started with a nice log-normal distribution and then generated fake constraints based on it.) One possibility is a straight interpolation through the midpoints of the constraints: mids = ({#1, Mean[{#2,#3}]}&) @@@ constraints f = Interpolation[mids, InterpolationOrder->0] Plotted, f looks like this: That sort of technically satisfies the constraints but it needs smoothing. We can increase the interpolation order but now it violates the implicit constraints (always less than one, and monotone): How can I get a curve that looks as much like the first one above as possible? Note that NonLinearModelFit with a LogNormalDistribution will do the trick in this example but is insufficiently general as sometimes there will sometimes not exist a log-normal distribution satisfying the constraints.

  • Can't wrap my head around appengine data store persistence

    - by aloo
    Hi, I've run into the "can't operate on multiple entity groups in a single transaction." problem when using APPENGINE FOR JAVA w/ JDO with the following code: PersistenceManager pm = PMF.get().getPersistenceManager(); Query q = pm.newQuery("SELECT this FROM " + TypeA.class.getName() + " WHERE userId == userIdParam "); q.declareParameters("String userIdParam"); List<TypeA> poos = (List<TypeA>) q.execute(userIdParam); for (TypeA a : allTypeAs) { a.setSomeField(someValue); } pm.close(); } The problem it seems is that I can't operate on a multiple entities at the same time b/c they arent in the same entity group while in a transaction. Even though it doesn't seem like I'm in a transaction, appengine generates one because I have the following set in my jdoconfig.xml: <property name="datanucleus.appengine.autoCreateDatastoreTxns" value="true"/> Fine. So far I think I understand. BUT - if I replace TypeA in the above code, with TypeB - I don't get the error. I don't believe there is anything different between type a and type b - they both have the same key structure. They do have different fields but that shouldn't matter, right? My question is - what could possible be different between TypeA and TypeB that they give this different behavior? And consequently what do you I fundamentally misunderstand that this behavior could even exist.... Thanks.

  • In symfony/doctrine's schema.yml, where should I put onDelete: CASCADE for a many-to-many relationsh

    - by nselikoff
    I have a many-to-many relationship defined in my Symfony (using doctrine) project between Orders and Upgrades (an Order can be associated with zero or more Upgrades, and an Upgrade can apply to zero or more Orders). # schema.yml Order: columns: order_id: {...} relations: Upgrades: class: Upgrade local: order_id foreign: upgrade_id refClass: OrderUpgrade Upgrade: columns: upgrade_id: {...} relations: Orders: class: Order local: upgrade_id foreign: order_id refClass: OrderUpgrade OrderUpgrade: columns: order_id: {...} upgrade_id: {...} I want to set up delete cascade behavior so that if I delete an Order or an Upgrade, all of the related OrderUpgrades are deleted. Where do I put onDelete: CASCADE? Usually I would put it at the end of the relations section, but that would seem to imply in this case that deleting Orders would cascade to delete Upgrades. Is Symfony + Doctrine smart enough to know what I'm wanting if I put onDelete: CASCADE in the above relations sections of schema.yml?

  • Many-To-Many dimensional model

    - by Mevdiven
    Folks, I have a dimension table called DIM_FILE which holds information of the files we received from customers. Each file has detail records which constitutes my FACT table, CUST_DETAIL. In the main process, file is gone through several stages and each stage tags a status to it. Long in a short, I have many-to-many relationship. Any ideas around star schema dimensional modeling. A customer record only belong to a single file and a file can have multiple statuses. FACT ---- CustID FileID AmountDue DIM_FILE -------- FileID FileName DateReceived FILE_STATUS ----------- FileID StatusDateTime StatusCode

  • Java appending XML data

    - by Travis
    I've already read through a few of the answers on this site but none of them worked for me. I have an XML file like this: <root> <character> <name>Volstvok</name> <charID>(omitted)</charID> <userID>(omitted)</userID> <apiKey>(omitted)</apiKey> </character> </root> I need to add another <character> somehow. I'm trying this but it does not work: public void addCharacter(String name, int id, int userID, String apiKey){ Element newCharacter = doc.createElement("character"); Element newName = doc.createElement("name"); newName.setTextContent(name); Element newID = doc.createElement("charID"); newID.setTextContent(Integer.toString(id)); Element newUserID = doc.createElement("userID"); newUserID.setTextContent(Integer.toString(userID)); Element newApiKey = doc.createElement("apiKey"); newApiKey.setTextContent(apiKey); //Setup and write newCharacter.appendChild(newName); newCharacter.appendChild(newID); newCharacter.appendChild(newUserID); newCharacter.appendChild(newApiKey); doc.getDocumentElement().appendChild(newCharacter); }

  • Is NSManagedObjectContext autosaved or am I looking at NSFetchedResultsController's cache?

    - by Andreas
    I'm developing an iPhone app where I use a NSFetchedResultsController in the main table view controller. I create it like this in the viewDidload of the main table view controller: NSSortDescriptor *sortDescriptorDate = [[NSSortDescriptor alloc] initWithKey:@"date" ascending:YES]; NSSortDescriptor *sortDescriptorTime = [[NSSortDescriptor alloc] initWithKey:@"start" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptorDate,sortDescriptorTime, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; [sortDescriptorDate release]; [sortDescriptorTime release]; [sortDescriptors release]; controller = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:context sectionNameKeyPath:@"date" cacheName:nil]; [fetchRequest release]; NSError *error; BOOL success = [controller performFetch:&error]; Then, in a subsequent view, I create a new object on the context: TestObject *testObject = [NSEntityDescription insertNewObjectForEntityForName:@"TestObject" inManagedObjectContext:context]; The TestObject has several related object which I create in the same way and add to the testObject using the provided add...Objects methods. Then, if before saving the context, I press cancel and go back to the main table view, nothing is shown as expected. However, if I restart the app, the object I created on the context shows in the main table view. How come? At first, I thought it was because the NSFetchedResultsController was reading from the cache, but as you can see I set this to nil just to test. Also, [context hasChanges] returns true after I restart. What am I missing here?

  • Transfer data between C++ classes efficiently

    - by David
    Hi, Need help... I have 3 classes, Manager which holds 2 pointers. One to class A another to class B . A does not know about B and vise versa. A does some calculations and at the end it puts 3 floats into the clipboard. Next, B pulls from clipboard the 3 floats, and does it's own calculations. This loop is managed by the Manager and repeats many times (iteration after iteration). My problem: Now class A produces a vector of floats which class B needs. This vector can have more than 1000 values and I don't want to use the clipboard to transfer it to B as it will become time consumer, even bottleneck, since this behavior repeats step by step. Simple solution is that B will know A (set a pointer to A). Other one is to transfer a pointer to the vector via Manager But I'm looking for something different, more object oriented that won't break the existent separation between A and B Any ideas ? Many thanks David

  • Is It Incorrect to Make Domain Objects Aware of The Data Access Layer?

    - by Noah Goodrich
    I am currently working on rewriting an application to use Data Mappers that completely abstract the database from the Domain layer. However, I am now wondering which is the better approach to handling relationships between Domain objects: Call the necessary find() method from the related data mapper directly within the domain object Write the relationship logic into the native data mapper (which is what the examples tend to do in PoEAA) and then call the native data mapper function within the domain object. Either it seems to me that in order to preserve the 'Fat Model, Skinny Controller' mantra, the domain objects have to be aware of the data mappers (whether it be their own or that they have access to the other mappers in the system). Additionally it seems that Option 2 unnecessarily complicates the data access layer as it creates table access logic across multiple data mappers instead of confining it to a single data mapper. So, is it incorrect to make the domain objects aware of the related data mappers and to call data mapper functions directly from the domain objects? Update: These are the only two solutions that I can envision to handle the issue of relations between domain objects. Any example showing a better method would be welcome.

  • Aggregate Functions on subsets of data based on current row values with SQL

    - by aasukisuki
    Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

  • PL/SQL profiler missing data

    - by user289429
    We are using pl/sql profiler to collect metrics. We noticed that on one of the environment the plsql_profiler_runs table is populated with the total execution time but the finer details that gets collected in the table plsql_profiler_data is missing. Any idea why this would be happening? We do use dbms_profiler.flush_data() before stopping the profiler and have seen this work fine in another environment.

  • How do I Data-Bind dual DateTimePicker to a single DateTime object

    - by S.C. Madsen
    Hi, I have a simple form, with two DateTimePicker-controls: One for date, and one for time. The thing is these two controls are supposed to represent a single point in time. Hence I would like to "Bind" them to a single DateTime property on my form (for simplicity). I did the following: // Start is a DateTime property on the form _StartDate.DataBindings.Add("Value", this, "Start"); _StartTime.DataBindings.Add("Value", this, "Start"); But hooking into "ValueChanged" event, yields mixed results... Sometimes I get exactly what I want, sometimes the updates of the property are "sluggish". I figured this way of splitting into two DateTimePicker's was fairly common. So how to do it? Update: There is possibly multiple questions in there: How do I bind a DateTimePicker (Format: Date) to a DateTime Property on a form? Then, how do I bind yet another DateTimePicker (Format: Time) to the same property? I'm using Visual Studio Express 2008 (.NET 3.5), and I seemingly get ValueChanged events from the DateTimePickers before the value is changed?

  • Google Maps Terms of Service - saving some data to a database

    - by R.M.
    I've read the terms of service, and, from what I understand, I'm not allowed to store any information I retrieve from the Google Maps API. Are there any exceptions to this? More to the point, I'm planning on building an application that shows the user several points of interest (like restaurants, libraries etc) at a certain distance around a location he chooses (it can be in one city or more, depending on the distance he chooses). There are two problems: The first problem is that (at least for my country) the geocoder doesn't locate exact addresses, at best it only locates street names (but completely ignores street numbers) in larger cities. It is even worse for smaller rural areas. So the only way to accurately show the places on the map is by storing their coordinates in the database. Another problem seems to be with calculating distances. To show the points located below a certain distance from the user, it would mean I would have to use GDirections to get all distances between the user's location and the other points, to see which ones to show. That would be really slow for the user (since I also have to set a small delay between requests), and it would also send a pretty large amount of requests to google. Would I be allowed to store those distances in a database? The users would not be able to access a list of all the stored information, they would only see the names of the places, and a map with some markers on it. Thank you.
