  • Javascript function to add class to a list element based on # in url.

    - by Jason
    I am trying to create a javascript function to add and remove a class to a list element based on the #tag at the end of the url on a page. The page has several different states, each with a different # in the url. I am currently using this script to change the style of a given element based on the # in the url when the user first loads the page, however if the user navigates to a different section of the page the style added on the page load stays, I would like it to change. <script type="text/javascript"> var hash=location.hash.substring(1); if (hash == 'strategy'){ document.getElementById('strategy_link').style.backgroundPosition ="-50px"; } if (hash == 'branding'){ document.getElementById('branding_link').style.backgroundPosition ="-50px"; } if (hash == 'marketing'){ document.getElementById('marketing_link').style.backgroundPosition ="-50px"; } if (hash == 'media'){ document.getElementById('media_link').style.backgroundPosition ="-50px"; } if (hash == 'management'){ document.getElementById('mangement_link').style.backgroundPosition ="-50px"; } if (hash == ''){ document.getElementById('shop1').style.display ="block"; } </script> Additionally, I am using a function to change the class of the element onClick, but when a user comes to a specific # on the page directly from another page and then clicks to a different location, two elements appear active. <script type="text/javascript"> function selectInList(obj) { $("#circularMenu").children("li").removeClass("highlight"); $(obj).addClass("highlight"); } </script> You can see this here: http://www.perksconsulting.com/dev/capabilities.php#branding Thanks.

  • properly format postal address with line breaks [google maps]

    - by munchybunch
    Using V3 of the google maps API, is there any reliable way to format addresses with the line break? By this, I mean something like 1600 Amphitheatre Parkway Mountain View, CA 94043 should be formatted as 1600 Amphitheatre Parkway Mountain View, CA 94043 Looking through the response object from geocoding, there is an address_components array that has, for the above address, 8 components (not all of the components are used for the address): 0: Object long_name: "1600" short_name: "1600" types: Array[1] 0: "street_number" length: 1 1: Object long_name: "Amphitheatre Pkwy" short_name: "Amphitheatre Pkwy" types: Array[1] 0: "route" length: 1 2: Object long_name: "Mountain View" short_name: "Mountain View" types: Array[2] 0: "locality" 1: "political" length: 2 3: Object long_name: "San Jose" short_name: "San Jose" types: Array[2] 0: "administrative_area_level_3" 1: "political" length: 2 4: Object long_name: "Santa Clara" short_name: "Santa Clara" types: Array[2] 0: "administrative_area_level_2" 1: "political" length: 2 5: Object long_name: "California" short_name: "CA" types: Array[2] 0: "administrative_area_level_1" 1: "political" length: 2 6: Object long_name: "United States" short_name: "US" types: Array[2] 0: "country" 1: "political" length: 2 7: Object long_name: "94043" short_name: "94043" types: Array[1] 0: "postal_code" length: 1 I was thinking that you could just combine parts that you want, like sprintf("%s %s<br />%s, %s %s", array[0].short_name, array[1].short_name, array[2].short_name, array[5].short_name, array[7].short_name) [edit]I just realized that sprintf isn't defined by default in JavaScript, so just a concatenation would do I guess.[/edit] But that seems awfully unreliable. Does anyone know the details on the structure of address_components, and if it's reliably similar like that for street addresses in the US? If I wanted to, I guess I could look for the proper types (street_number,route, etc) as well. I'd love it if anyone had a better way than what I"m doing here...

  • specifying multiple URLs with cURL/PHP using square brackets

    - by Raj Gundu
    I have a large array of URLS similar to this: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); The cURL manual states here (http://curl.haxx.se/docs/manpage.html) that i can use square brackets '[]' to specify multiple urls. Used in the above example this would be similar to this: 'http://www.example.com/product.php?page=[1-3]&sortOn=sellprice' So far i have been unable to reference this correctly. This is the complete code segment I'm currently trying to utilize this with: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); $node_count = count($nodes); $curl_arr = array(); $master = curl_multi_init(); for($i = 0; $i < $node_count; $i++) { $url =$nodes[$i]; $curl_arr[$i] = curl_init($url); curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true); curl_multi_add_handle($master, $curl_arr[$i]); } do { curl_multi_exec($master,$running); } while($running > 0); echo "results: "; for($i = 0; $i < $node_count; $i++) { $results = curl_multi_getcontent ( $curl_arr[$i] ); echo( $i . "\n" . $results . "\n"); echo 'done'; I can't seem to find any more documentation on this. Thanks in advance.

  • Simulated Annealing and Yahtzee!

    - by Jasie
    I've picked up Programming Challenges and found a Yahtzee! problem which I will simplify: There are 13 scoring categories There are 13 rolls by a player (comprising a play) Each roll must fit in a distinct category The goal is to find the maximum score for a play (the optimal placement of rolls in categories); score(play) returns the score for a play Brute-forcing to find the maximum play score requires 13! (= 6,227,020,800) score() calls. I choose simulated annealing to find something close to the highest score, faster. Though not deterministic, it's good enough. I have a list of 13 rolls of 5 die, like: ((1,2,3,4,5) #1 (1,2,6,3,4),#2 ... (1,4,3,2,2) #13 ) And a play (1,5,6,7,2,3,4,8,9,10,13,12,11) passed into score() returns a score for that play's permutation. How do I choose a good "neighboring state"? For random-restart, I can simply choose a random permutation of nos. 1-13, put them in a vector, and score them. In the traveling salesman problem, here's an example of a good neighboring state: "The neighbours of some particular permutation are the permutations that are produced for example by interchanging a pair of adjacent cities." I have a bad feeling about simply swapping two random vector positions, like so: (1,5,6,7, 2 , 3,4,8,9,10, 13, 12,11) # switch 2 and 13 (1,5,6,7, 13, 3,4,8,9,10, 2 , 12,11) # now score this one But I have no evidence and don't know how to select a good neighboring state. Anyone have any ideas on how to pick good neighboring states?

  • erlang design of a card game [closed]

    - by user601836
    I would like to discuss with you a possible implementation for a card game in erlang. The only full example I found online is OpenPoker. I would like to create one myself, so here is the implementation I have in mind: A gen_server to represent a deck: when started creates a deck of cards (shuffled). And stores it in its state. provides an handle_call (draw_card) A gen_server to represent the chat room. Stores in its state the registered name of a player process (e.g. player1, player2, luke etc etc). Exports handle_cast to join the chat (executed by default when somebody joins successfully the game) and one to broadcast a chat message to all users by calling an handle_cast on the gen_server representing a player. a gen_fsm to represent a game instance. Has two states (wait_join, and turn). Exports join/1 to join the game, play_card/2 and send_msg/2. One parameter is the pid of the player process. a gen_server to represent the player. Exports only start_link/1 where the parameter is the name to use to register the process (inside the init I call join method of gen_fsm). Has different handle_calls (e.g. get_hand, draw_card) and handle_casts (e.g. play_card, deliver_msg, and send_msg) A gen_server to represent the main process. Exports (join_game/1 which calls player:start_link/1, send_msg/2 to call player's send_msg, play_card/3 to call player's play_card). What do you think of this architecture? Thanks in advance

  • Push TFS 2008 code to remote VSS over VPN?

    - by drovani
    We have a local Team Foundation Server 2008 that we keep our code under version control. However, we also have a paranoid client that has their own Visual Source Safe installation that wants us to keep a running copy of the code on their server as well. As such, I'm hoping there is a way I can just do a nightly push from our TFS repository to their VSS repository. I'm not concerned about keeping each changeset on TFS as a different changeset on the VSS, just a once-nightly push that creates a new changeset on the VSS and uploads the latest changeset from TFS. I guess the first part is if it is even possible for TFS to push an update to VSS. I've noticed that most replies to this question have been something to the tune of "don't do it", but I can't find anything that specifically states that it cannot be done. The second part would then be automating the process by having the TFS server connect to the client's VPN, then push the code changes. I have full control over the TFS server and I can customize the VSS install, if there are settings that need changing, but I'm limited on what I can do about settings on either firewall or server specific settings on the client's VSS server.

  • Java: Clearing up the confusion on what causes a connection reset

    - by Zombies
    There seems to be some confusion as well contradicting statements on various SO answers: http://stackoverflow.com/questions/585599/whats-causing-my-java-net-socketexception-connection-reset . You can see here that the accepted answer states that the connection was closed by other side. But this is not true, closing a connection doesn't cause a connection reset. It is cauesed by "an underlying TCP/IP error." What I want to know is if a SocketException: Connection reset means really besides "unerlying TCP/IP Error." What really causes this? As I doubt it has anything to do with the connection being closed (since closing a connection isn't an exception worthy flag, and reading from a closed connection is, but that isn't an "underlying TCP/IP error." My hypothesis is this Connection reset is caused from a server's failure to acknowledge an ACK packet (either wholly or just improperly as per TCP/IP). And that a SocketTimeoutException is generated only when no data is generated to be read (since this is thrown during a read after a certain duration, and read is waiting for data, but is not concerned with ACK packets). In other words, read() throws SocketTimeoutException if it didn't read any bytes of actual data (DATA LAYER) in its allotted time.

  • Rails helper module undefined method `sort'

    - by Magicked
    I'm trying to create a simple helper module in rails, and I'm stumped on the following error message from my new person form (app/views/people/new.html.erb): undefined method `sort' for 97:Fixnum Extracted source (around line #17): 14: <p> 15: <% nations = { 'United States of America' => 'USA', 'Canada' => 'Canada', 'Mexico' => 'Mexico', 'United Kingdom' => 'UK' } %> 16: <%= f.label :country %><br /> 17: <%= radio_buttons(:person, :country, nations) %> 18: 19: </p> 20: <p> radio_buttons is a helper module I have created for my view. Here it is (app/helpers/people_helper.rb): module PeopleHelper def radio_buttons(model_name, target_property, button_source) html='' list = button_source.sort list.each do |x| html << radio_buttons(model_name, target_property, x[1]) html << h(x[0]) html << '<br />' end return html end end The problem appears to be on the "list = button_source.sort", but I'm not sure why it says the method is undefined. I have been able to use it directly within my view code. Am I not able to use methods like this within helper modules? Do I need to include something? Thanks for any help!

  • Ideas on frameworks in .NET that can be used for job processing and notifications

    - by Rajat Mehta
    Scenario: We have one instance of WCF windows service which exposes contracts like: AddNewJob(Job job), GetJobs(JobQuery query) etc. This service is consumed by 70-100 instances of client which is Windows Form based .NET app. Typically the service has 50-100 inward calls/minute to add or query jobs that are stored in a table on Sql Server. The same service is also responsible for processing these jobs in real time. It queries database every 5 seconds picks up the queued jobs and starts processing them. A job has 6 states. Queued, Pre-processing, Processing, Post-processing, Completed, Failed, Locked. Another responsibility on this service is to update all clients on every state change of every job. This means almost 200+ callbacks to clients per second. Question: This whole implementation is done using WCF Duplex bindings and works perfectly fine on small number of parallel jobs. Problem arises when we scale it up to 1000 jobs at a time. The notifications don't work as expected, it leads to memory overflow etc. Is there any standard framework that can provide a clean infrastructure for handling this scenario?? Apologies for the long explanation!

  • How do I install the OpenSSL C++ library on Ubuntu?

    - by Daryl Spitzer
    I'm trying to build some code on Ubuntu 10.04 LTS that uses OpenSSL 1.0.0. When I run make, it invokes g++ with the "-lssl" option. The source includes: #include <openssl/bio.h> #include <openssl/buffer.h> #include <openssl/des.h> #include <openssl/evp.h> #include <openssl/pem.h> #include <openssl/rsa.h> I ran: $ sudo apt-get install openssl Reading package lists... Done Building dependency tree Reading state information... Done openssl is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded. But I guess the openssl package doesn't include the library. I get these errors on make: foo.cpp:21:25: error: openssl/bio.h: No such file or directory foo.cpp:22:28: error: openssl/buffer.h: No such file or directory foo.cpp:23:25: error: openssl/des.h: No such file or directory foo.cpp:24:25: error: openssl/evp.h: No such file or directory foo.cpp:25:25: error: openssl/pem.h: No such file or directory foo.cpp:26:25: error: openssl/rsa.h: No such file or directory How do I install the OpenSSL C++ library on Ubuntu 10.04 LTS? I did a man g++ and (under "Options for Linking") for the -l option it states: " The linker searches a standard list of directories for the library..." and "The directories searched include several standard system directories..." What are those standard system directories?

  • PHP's openssl_sign generates different signature than SSCrypto's sign

    - by pascalj
    I'm writing an OS X client for a software that is written in PHP. This software uses a simple RPC interface to receive and execute commands. The RPC client has to sign the commands he sends to ensure that no MITM can modify any of them. However, as the server was not accepting the signatures I sent from my OS X client, I started investigating and found out that PHP's openssl_sign function generates a different signature for a given private key/data combination than the Objective-C SSCrypto framework (which is only a wrapper for the openssl lib): SSCrypto *crypto = [[SSCrypto alloc] initWithPrivateKey:self.localPrivKey]; NSData *shaed = [self sha1:@"hello"]; [crypto setClearTextWithData:shaed]; NSData *data = [crypto sign]; generates a signature like CtbkSxvqNZ+mAN... The PHP code openssl_sign("hello", $signature, $privateKey); generates a signature like 6u0d2qjFiMbZ+... (For my certain key, of course. base64 encoded) I'm not quite shure why this is happening and I unsuccessfully experimented with different hash-algorithms. As the PHP documentation states SHA1 is used by default. So why do these two functions generate different signatures and how can I get my Objective-C part to generate a signature that PHPs openssl_verify will accept? Note: I double checked that the keys and the data is correct!

  • CCAnimate/CCAnimation cause inconsistent setTexture behavior in cocos2d on iPhone

    - by chillid
    Hi, I have a character that goes through multiple states. The state changes are reflected by means of a sprite image (texture) change. The state change is triggered by a user tapping on the sprite. This works consistently and quite well. I then added an animation during State0. Now, when the user taps - setTexture gets executed to change the texture to reflect State1, however some of the times (unpredictable) it does not change the texture. The code flows as below: // 1. // Create the animation sequence CGRect frame1Rect = CGRectMake(0,32,32,32); CGRect frame2Rect = CGRectMake(32,32,32,32); CCTexture2D* texWithAnimation = [[CCTextureCache sharedTextureCache] addImage:@"Frames0_1_thinkNthickoutline32x32.png"]; id anim = [[[CCAnimation alloc] initWithName:@"Sports" delay:1/25.0] autorelease]; [anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame1Rect offset:ccp(0,0)]]; [anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame2Rect offset:ccp(0,0)]]; // Make the animation sequence repeat forever id myAction = [CCAnimate actionWithAnimation: anim restoreOriginalFrame:NO]; // 2. // Run the animation: sports = [[CCRepeatForever alloc] init]; [sports initWithAction:myAction]; [self.sprite runAction:sports]; // 3. stop action on state change and change texture: NSLog(@"Stopping action"); [sprite stopAction:sports]; NSLog(@"Changing texture for kCJSports"); [self setTexture: [[CCTextureCache sharedTextureCache] addImage:@"SportsOpen.png"]]; [self setTextureRect:CGRectMake(0,0,32,64)]; NSLog(@"Changed texture for kCJSports"); Note that all the NSLog lines get logged - and the texture RECT changes - but the image/texture changes only some of the times - fails for around 10-30% of times. Locking/threading/timing issue somewhere? My app (game) is single threaded and I only use the addImage and not the Async version. Any help much appreciated.

  • How to create a chart from mysql data?

    - by user187580
    Hello, I have some data and want to create some dynamic charts. I have looked on Google visualisation api .. It looks great but the problem is I am not very familiar with it. Any ideas, how I can set the data.setValue from mysql data. <script type='text/javascript'> google.load('visualization', '1', {'packages': ['geomap']}); google.setOnLoadCallback(drawMap); function drawMap() { var data = new google.visualization.DataTable(); data.addRows(6); data.addColumn('string', 'Country'); data.addColumn('number', 'Popularity'); data.setValue(0, 0, 'Germany'); data.setValue(0, 1, 200); data.setValue(1, 0, 'United States'); data.setValue(1, 1, 300); data.setValue(2, 0, 'Brazil'); data.setValue(2, 1, 400); data.setValue(3, 0, 'Canada'); data.setValue(3, 1, 500); data.setValue(4, 0, 'France'); data.setValue(4, 1, 600); data.setValue(5, 0, 'RU'); data.setValue(5, 1, 700); var options = {}; options['dataMode'] = 'regions'; var container = document.getElementById('map_canvas'); var geomap = new google.visualization.GeoMap(container); geomap.draw(data, options); }; </script> I can create chart using some other methods but just interested in using Google Visualisation API. Thanks.

  • Question about cloning in Java

    - by devoured elysium
    In Effective Java, the author states that: If a class implements Cloneable, Object's clone method returns a field-by-field copy of the object; otherwise it throws CloneNotSupportedException. What I'd like to know is what he means with field-by-field copy. Does it mean that if the class has X bytes in memory, it will just copy that piece of memory? If yes, then can I assume all value types of the original class will be copied to the new object? class Point { private int x; private int y; @Override public Point clone() { return (Point)super.clone(); } } If what Object.clone() does is a field by field copy of the Point class, I'd say that I wouldn't need to explicitly copy fields x and y, being that the code shown above will be more than enough to make a clone of the Point class. That is, the following bit of code is redundant: @Override public Point clone() { Point newObj = (Point)super.clone(); newObj.x = this.x; //redundant newObj.y = this.y; //redundant } Am I right? I know references of the cloned object will point automatically to where the original object's references pointed to, I'm just not sure what happens specifically with value types. If anyone could state clearly what Object.clone()'s algorithm specification is (in easy language) that'd be great. Thanks

  • Regular expression for dividing country calling codes

    - by RickiG
    Hi I have a list of calling codes for all countries(the phone number prefixes), I would like to split them up in the country name and the actual code so I can put then into an xml. I have tried back and forth but can not get a regexp going that takes all cases into account. I think it is fairly simple for someone with a bit of experience. The codes have these formats: Afghanistan 93 Anguilla 1 264 Antarctica 6721 Antigua and Barbuda 1 268 Bosnia and Herzegovina 387 Canada 1 Congo, Republic of the 242 Cote d'Ivoire 225 Ireland (Eire) 353 United States of America 1 There are around 235 of them in total, but these are the regulars and the exceptions. ^[a-zA-Z]\s,'()] for between 1 and X words and then it is [0-9\s]{1,5}$ for the numbers: X XX XXX XXXX X XXX So if I should express it as a sentence it would be: "from beginning of a line, take all characters (1) including space,'() until you encounter digits, then take all of these including space(2) until you encounter a line break." I am using TextMate, and the docs says: TextMate uses the Oniguruma regular expression library by K. Kosako. I would appreciate any help given:) Thank you.

  • Silverlight MVVM Confusion: Updating Image Based on State

    - by senfo
    I'm developing a Silverlight application and I'm trying to stick to the MVVM principals, but I'm running into some problems changing the source of an image based on the state of a property in the ViewModel. For all intents and purposes, you can think of the functionality I'm implementing as a play/pause button for an audio app. When in the "Play" mode, IsActive is true in the ViewModel and the "Pause.png" image on the button should be displayed. When paused, IsActive is false in the ViewModel and "Play.png" is displayed on the button. Naturally, there are two additional images to handle when the mouse hovers over the button. I thought I could use a Style Trigger, but apparently they're not supported in Silverlight. I've been reviewing a forum post with a question similar to mine where it's suggested to use the VisualStateManager. While this might help with changing the image for hover/normal states, the part missing (or I'm not understanding) is how this would work with a state set via the view model. The post seems to apply only to events rather than properties of the view model. Having said that, I also haven't successfully completed the normal/hover affects, either. Below is my Silverlight 4 XAML. It should also probably be noted I'm working with MVVM Light. <UserControl x:Class="Foo.Bar.MyUserControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" mc:Ignorable="d" d:DesignHeight="100" d:DesignWidth="200"> <UserControl.Resources> <Style x:Key="MyButtonStyle" TargetType="Button"> <Setter Property="IsEnabled" Value="true"/> <Setter Property="IsTabStop" Value="true"/> <Setter Property="Background" Value="#FFA9A9A9"/> <Setter Property="Foreground" Value="#FF000000"/> <Setter Property="MinWidth" Value="5"/> <Setter Property="MinHeight" Value="5"/> <Setter Property="Margin" Value="0"/> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalAlignment" Value="Top" /> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Cursor" Value="Hand"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid> <Image Source="/Foo.Bar;component/Resources/Icons/Bar/Play.png"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="Active"> <VisualState x:Name="MouseOver"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="/Foo.Bar;component/Resources/Icons/Bar/Play_Hover.png" /> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Button Style="{StaticResource MyButtonStyle}" Command="{Binding ChangeStatus}" Height="30" Width="30" /> </Grid> </UserControl> What is the proper way to update images on buttons with the state determined by the view model? Update I changed my Button to a ToggleButton hoping I could use the Checked state to differentiate between play/pause. I practically have it, but I ran into one additional problem. I need to account for two states at the same time. For example, Checked Normal/Hover and Unchecked Normal/Hover.

  • Modelling deterministic and nondeterministic data separately

    - by Superstringcheese
    I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

  • Insert data in an object to a database.

    - by paul
    I am facing the following design/implementation dilemma. I have a class Customer which is below with getters and setters. I would like to insert the value of the Customer into a "Customer" table of a database. But Customer has an address which is of type "Address". How do I go about inserting this field into the database?(I am using sqlite3). I thought of writing a separate table "Address(customerId,doorNo,city,state,country,pinCode)". But I am having second thoughts about generating the primary key(customerId) which should be same for both the "customer" and "Address" table. Sqlite3 faq states that I can do "Integer Primary Key" to use the field to generate an auto number. But if I do that in customer table, I would have to retrieve the same Id to be used in Address table. This kinda looks wrong to me :-?. There should be an elegant method to solve this. Any ideas would be much appreciated. Thanks in advance. import java.io.*; import java.sql.*; class Customer { private String id; private String name; private Address address; private Connection connection; private ResultSet resultSet; private PreparedStatement preparedStatement; public void insertToDatabase(){ } } class Address{ private String doorNumber; private String streetName; private String cityName; private String districtName; private String stateName; private String countryName; private long pinCode; }

  • Colorizing as SAS Map

    - by user601828
    I'm trying to generate a map in SAS where I would like to to make gradual color changes which correspond to my results. So the higher the counts the more intense the color changes. Also I would like to add state labels to the map. Here is my code, so far it produces a white map with varying degress of blue blocks. I'd like the states colored in intense colors, like red, bright pink,brilliant, blues and greens. Can anyone please help me modify the code to add state labels and colorize the map, and below the map add a table summarizing the statistics, like counts and percentages. Thanks in advance. goptions gunit=pct cback=white htitle=4 htext=3 colors=(PAGY LIY STY DEGY dark_yellow very_dark_yellow ) ; title "My Map Results"; proc gmap map=maps.us data=My_data all; id state; block person_per_event/levels=6; choro person_per_event/levels=6; run; quit; I looked at his page before for example if I wanted to make a map like this one http://robslink.com/SAS/democd61/election_2012.htm with my data. I tried modifying the code that he gives on the link, but wasnt very successful. I would like to use that map along with the state labels and keep the colors and represent my data with blocks in the corresponding locations with city and state, and high level counts. The rest of the summary statistics I would like to summarize in a colorful table next to the map, like a dashboard of sorts. Appreciate any help in advance. Thanks, -rachel

  • Ideas Related to Subset Sum with 2,3 and more integers

    - by rolandbishop
    I've been struggling with this problem just like everyone else and I'm quite sure there has been more than enough posts to explain this problem. However in terms of understanding it fully, I wanted to share my thoughts and get more efficient solutions from all the great people in here related to Subset Sum problem. I've searched it over the Internet and there is actually a lot sources but I'm really willing to re-implement an algorithm or finding my own in order to understand fully. The key thing I'm struggling with is the efficiency considering the set size will be large. (I do not have a limit, just conceptually large). The two phases I'm trying to implement ideas on is finding two numbers that are equal to given integer T, finding three numbers and eventually K numbers. Some ideas I've though; For the two integer part I'm thing basically sorting the array O(nlogn) and for each element in the array searching for its negative value. (i.e if the array element is 3 searching for -3). Maybe a hash table inclusion could be better, providing a O(1) indexing the element? For the three or more integers I've found an amazing blog post;http://www.skorks.com/2011/02/algorithms-a-dropbox-challenge-and-dynamic-programming/. However even the author itself states that it is not applicable for large numbers. So I was for 2 and 3 and more integers what ideas could be applied for the subset problem. I'm struggling with setting up a dynamic programming method that will be efficient for the large inputs as well.

  • Python's asyncore to periodically send data using a variable timeout. Is there a better way?

    - by Nick Sonneveld
    I wanted to write a server that a client could connect to and receive periodic updates without having to poll. The problem I have experienced with asyncore is that if you do not return true when dispatcher.writable() is called, you have to wait until after the asyncore.loop has timed out (default is 30s). The two ways I have tried to work around this is 1) reduce timeout to a low value or 2) query connections for when they will next update and generate an adequate timeout value. However if you refer to 'Select Law' in 'man 2 select_tut', it states, "You should always try to use select() without a timeout." Is there a better way to do this? Twisted maybe? I wanted to try and avoid extra threads. I'll include the variable timeout example here: #!/usr/bin/python import time import socket import asyncore # in seconds UPDATE_PERIOD = 4.0 class Channel(asyncore.dispatcher): def __init__(self, sock, sck_map): asyncore.dispatcher.__init__(self, sock=sock, map=sck_map) self.last_update = 0.0 # should update immediately self.send_buf = '' self.recv_buf = '' def writable(self): return len(self.send_buf) > 0 def handle_write(self): nbytes = self.send(self.send_buf) self.send_buf = self.send_buf[nbytes:] def handle_read(self): print 'read' print 'recv:', self.recv(4096) def handle_close(self): print 'close' self.close() # added for variable timeout def update(self): if time.time() >= self.next_update(): self.send_buf += 'hello %f\n'%(time.time()) self.last_update = time.time() def next_update(self): return self.last_update + UPDATE_PERIOD class Server(asyncore.dispatcher): def __init__(self, port, sck_map): asyncore.dispatcher.__init__(self, map=sck_map) self.port = port self.sck_map = sck_map self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.bind( ("", port)) self.listen(16) print "listening on port", self.port def handle_accept(self): (conn, addr) = self.accept() Channel(sock=conn, sck_map=self.sck_map) # added for variable timeout def update(self): pass def next_update(self): return None sck_map = {} server = Server(9090, sck_map) while True: next_update = time.time() + 30.0 for c in sck_map.values(): c.update() # <-- fill write buffers n = c.next_update() #print 'n:',n if n is not None: next_update = min(next_update, n) _timeout = max(0.1, next_update - time.time()) asyncore.loop(timeout=_timeout, count=1, map=sck_map)

  • How to send Event signal through Processes - C

    - by Jamie Keeling
    Hello all! I have an application consisting of two windows, one communicates to the other and sends it a struct constaining two integers (In this case two rolls of a dice). I will be using events for the following circumstances: Process a sends data to process b, process b displays data Process a closes, in turn closing process b Process b closes a, in turn closing process a I have noticed that if the second process is constantly waiting for the first process to send data then the program will be just sat waiting, which is where the idea of implementing threads on each process occurred and I have started to implement this already. The problem i'm having is that I don't exactly have a lot of experience with threads and events so I'm not sure of the best way to actually implement what I want to do. I'm trying to work out how the other process will know of the event being fired so it can do the tasks it needs to do, I don't understand how one process that is separate from another can tell what the states the events are in especially as it needs to act as soon as the event has changed state. Thanks for any help Edit: I can only use the Create/Set/Open methods for events, sorry for not mentioning it earlier.

  • Drupal WebForm with CCK content types. For anonymous users.

    - by thepearson
    I am probably asking a noob question... however: I have a Drupal site that the customer has a web form where anonymous users can fill in to order some posters (there is 3 to choose from). These are free and at the moment they user just states in the body of a textarea what posters they want. The site owner wants to now add more posters and now wants the ability to have each poster listed in the web form with a field for quantity next to them. When the web for is submitted it will post the node title and quantity to the web form along with the required information. I have researched using UC but it's too much of a eCom solution for such a simple requirement. I also looked at SimpleCart, Flag and Session favorites, all of which aren't really what I need. So I am looking for a simple way to itterate over all the "Poster" content types, and display them on the webform page with a quantity numerical field to be submitted with the web form for each poster. Currently I have: CCK Poster Title Image WebForm OrderPoster Name Email Address Details What I am looking for is a page that does the following: WebForm OrderPosters: Poster 1 [form qty text input for poster 1] Poster 2 [form qty text input for poster 2] Poster 3 [form qty text input for poster 3] ... Poster n [form qty text input for posters n] Name Email Address Details I'd imagine there is a simple way to do this, but I can't seem to find articles of customizing "WebForm" forms. Any help would be much appreciated.

  • Reporting Services: Tablix RepeatColumnHeaders doesn't work on some reports

    - by I Have the Hat
    So I've got various reports that consist of a DataSet rendered in a Tablix... pretty garden variety stuff. There is a property for the Tablix control named RepeatColumnHeaders, which I have set to True for each report in question. The explanation for this property states “Indicates whether column headers are repeated on each page on which part of the data region appear.” Sounds pretty straightforward, but on some reports it works and on others it does not. I can't seem to find what's different about the reports that might affect this. On one report where the headers do repeat, there is some fairly arcane grouping mojo, but in an example where it doesn't work the Tablix only has one level--no grouping. I would expect the multi-nested one to be the problem, not the flat one. Maybe it's a different problem altogether. I threw together a simple Tablix rendering SELECT * FROM Foo, accepted all the default values, which results in RepeatColumnHeaders being set to False, and lo and behold the column headers do repeat for that report... Grrr. Any insights greatly appreciated.

  • Search engine recommendation for 100 sites of about 4000 pages

    - by fwkb
    I am looking for a search engine that can regularly (daily-ish) scan about 100 pages for changes and index an associated site if changes since the last scan are found. It should be able to handle about 100 sites, each averaging 4000 pages of about 5k average size, each on a different server (but only the one centralized search engine). Each of these sites will have a search form that gets submitted to this search engine. The results that are returned must be specific to the site that submitted them. I create the templates for the external sites, so I can give the search form a hidden field that specifies which site the form is submitted from. What would you recommend I look into? I would love to use a Python-based system for this, if feasible. I am currently using something called iSearch2. It doesn't seem very stable at this scale, the description of the product states it is not really intended to do multiple sites, is in PHP (which is less comfortable to me than Python), and has a few other shortcomings for my specific situation.
