    Hello everyone! Is it possible to load an html document into a DOM javascript object so that you can read the elements in the document? For example, if I have a file on the server Test.html. Can the page Hello.html call javascript code to load Test.html into a DOM object? Please let me know. Thanks

  • are deleted entries counted in the load factor of a hash table using open addressing

    - by Dr. Monkey
    When calculating the load factor of a hashtable with an open-addressing array implementation I am using: numberOfKeysInArray/sizeOfArray however it occurred to me that since deleted entries must be marked as such (to distinguish them from empty spaces), it might make sense to include these in the number of keys. My thinking is that as far as estimating the average number of probes to find an entry, deleted entries should count towards the load factor, but as far as inserting a new key they should not. Which is the proper calculation: including deleted keys or not?

  • Balancing game difficulty against player progression

    - by Raven Dreamer
    It seems that the current climate of games seems to cater to an obvious progression of player power, whether that means getting a bigger, more explosive gun in Halo, leveling up in an RPG, or unlocking new options in Command and Conquer 4. Yet this concept is not exclusive to video or computer games -- even in Dungeons and Dragons players can strive to acquire a +2 sword to replace the +1 weapon they've been using. Yet as a systems designer, the concept of player progression is giving me headache after headache. Should I balance around the players exact capabilities and give up on a simple linear progression? (I think ESIV:Oblivion is a good example of this) Is it better to throw the players into an "arms race" with their opponents, where if the players don't progress in an orderly manner, it is only a matter of time until gameplay is unbearably difficult? (4th Edition DnD strikes me as a good example of this) Perhaps it would make most sense to untether the core gameplay mechanics from progression at all -- give them flashier, more interesting (but not more powerful!) ways to grow?

  • Balancing agressive invites

    - by Nils Munch
    I am designing a trading card game for mobiles, with the possibility to add cards to your collection using Gems, aquired through victories and inapp purchases. I am thinking to increase the spread of the game with a tracking system on game invites, enabling the user to invite a friend to play the game. If the friend doesn't own the game client (which is free) he will be offered to download it. If he joins the game, the original player earns X amount of gems as an reward. There can only be one player per mobile device, which should rule out some harvesting. My question is, how do you think the structure of this would be recieved ? All invites are mail based, unless the player already exists in the game world (then he gets a ingame invitation.) I have set a flood filter, so a player can only invite a friend (without the client installed) once a month.

  • Network Load Balancing and AnyCast Routing

    - by user126917
    Hi All can anyone advise on problems with the following? I am planning on installing the following setup on my estate: I have 2 sites that both have a large amount of users. Goals are to keep things simple for the users and to have automatic failover above the database level. Our Database will exist at the primary site and be async mirrored to the secondary site with manual failover procedures.The database generate sequential ID's so distributing it is not an option. I plan to site IIS boxes at both sites with all of the business logic on them and heavy operations. The connections to SQL will be lightweight and DB reads will be cached on IIS. On this layer I plan to use Windows network load balancing and have the same IP or IPs across all IIS boxes at both sites. This way there will be automatic failover and no single point of failure. Also users can have one web address regardless of which site they are in automatically be network load balanced to their local IIS. This is great but obviously our two sites are on different subnets and as this will be one IP address with most of our traffic we can't go broadcasting everything across the link between the sites. To solve this problem we plan to use AnyCast routing over our network layer to route the traffic to the most local box that is listening which will be defined by the network load balancing. Has anyone used this setup before? Can anyone think of any issues with this? Also some specifics I can't find anywhere at the moment. If my Windows box is assigned an IP and listening on that IP but network load balancing is not accepting specific traffic then will AnyCast route away from that? Also can I AnyCast on a socket level?

  • Balancing full time work and personal coding projects.

    - by pllee
    I am nearing the end of developing the major pieces of my website that I have been working on in my spare time for the last 3 months. My goal is to get it released by the end of next month and hopefully start making some money on it. Unfortunately the next step will be to write a lot of specific data handling and ui code that I can see becoming very tedious and boring. When I was first started the project I was able to find time for working on it easily, it was interesting and writing the back-end was new. Once I got to the start of writing stuff that I know and do at work (ui), it seemed harder and harder to make myself work on the project, sometimes the last thing I want to do when I get home from work is code again. Anyone in the same situation? Any tips on how to find time and effort for side projects without burning out? Any tips on staying on the right track?

  • Balancing dependency injection with public API design

    - by kolektiv
    I've been contemplating how to balance testable design using dependency injection with providing simple fixed public API. My dilemma is: people would want to do something like var server = new Server(){ ... } and not have to worry about creating the many dependencies and graph of dependencies that a Server(,,,,,,) may have. While developing, I don't worry too much, as I use an IoC/DI framework to handle all that (I'm not using the lifecycle management aspects of any container, which would complicate things further). Now, the dependencies are unlikely to be re-implemented. Componentisation in this case is almost purely for testability (and decent design!) rather than creating seams for extension, etc. People will 99.999% of the time wish to use a default configuration. So. I could hardcode the dependencies. Don't want to do that, we lose our testing! I could provide a default constructor with hard-coded dependencies and one which takes dependencies. That's... messy, and likely to be confusing, but viable. I could make the dependency receiving constructor internal and make my unit tests a friend assembly (assuming C#), which tidies the public API but leaves a nasty hidden trap lurking for maintenance. Having two constructors which are implicitly connected rather than explicitly would be bad design in general in my book. At the moment that's about the least evil I can think of. Opinions? Wisdom?

  • Balancing Player vs. Monsters: Level-Up Curves

    - by ashes999
    I've written a fair number of games that have RPG-like "levelling up," where the player gains experience for killing monsters/enemies, and eventually, reaches a new level, where their stats increase. How do you find a balance between player growth, monster strength, and difficulty? The extreme ends of this spectrum are: Player levels up really fast and blows away monsters without much effort Monsters are incredibly strong and even at low levels, are very difficult to beat I've also tried a strange situation of making enemies relative to players, i.e. an enemy will always be at 50% or 100% or 150% of player stats (thus requiring the player to use other techniques instead of brute strength to succeeed). But where's the balance, and how do you find it? Edit: For example, I am expecting to hear things like: Balance high instead of balance low (200 HP and 20 str is easier to balance than 20 HP and 2 str) Look at easiest vs. hardest monsters, and see what you have in terms of a range

  • Growing a small hosting company [closed]

    - by user2353007
    We currently have a few servers, 1 WHM VPS (2GB), 1 MS SQL VPS (2 GB), and 1 IIS VPS (2GB). The VPS servers are doing fine as far as uptime and response times but we would like to add the following features. 1) monitoring with load statistics 2) failover I have looked a Zabbix, Zenoss, Nagios, and a couple of other cloud solutions like monitor.us and watchdog from Zerigo. Ideally for the monitoring solution. Our current hosting company suggested we get a dedicated server or VPS and install load balancing software (not sure I like that idea). I've looked into Rackspace and Amazon load balancers which seem like the most feasible solutions for load balancers. Does anybody have any input on the monitoring and load balancing products I'm looking into? Monitoring should monitor uptime as well as give reports on memory usage, disk usage, processor usage, and which processes/websites/users are responsible for the load. It would be ideal if the load balancer worked with any IP. Not sure if either Rackspace or Amazon load balancers would allow load balancing with servers outside their datacenter. Thank you.

  • .NET load assembly error metabase config

    - by peter
    Hi, Yesterday I found out that the mailroot directory had moved to a different location on the C drive. I don't know how this happened as no configs were changed, using IIS7 with IIS6 SMTP service on Windows 2008 R2 web edition. I wanted to restore it to the default c:\inetpub\mailroot location. So I opened system32/inetsrv/MetaBase.xml, and in the node was the problem, BadMailDirectory, DropDirectory etc were all pointing to the wrong location... I changed them back to the default c:\inetpub\mailroot. Later I discovered an ASP.NET application was throwing this error: An error occurred in the Microsoft .NET Framework while trying to load assembly id 1. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error: System.IO.FileNotFoundException: Could not load file or assembly 'microsoft.sqlserver.types, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified. I figured it had to do with my changes to the mailroot locations, so I gave ASP.NET access to the mailroot directory and it was working.... My question is, how is this possible? Why does APS.NET require access to the mailroot directory to load assemblies? Thanks

  • Flash AS3 load file xml

    - by Elias
    Hello, I'm just trying to load an xml file witch can be anywere in the hdd, this is what I have done to browse it, but later when I'm trying to load the file it would only look in the same path of the swf file here is the code package { import flash.display.Sprite; import flash.events.; import flash.net.; public class cargadorXML extends Sprite { public var cuadro:Sprite = new Sprite(); public var file:FileReference; public var req:URLRequest; public var xml:XML; public var xmlLoader:URLLoader = new URLLoader(); public function cargadorXML() { cuadro.graphics.beginFill(0xFF0000); cuadro.graphics.drawRoundRect(0,0,100,100,10); cuadro.graphics.endFill(); cuadro.addEventListener(MouseEvent.CLICK,browser); addChild(cuadro); } public function browser(e:Event) { file = new FileReference(); file.addEventListener(Event.SELECT,bien); file.browse(); } public function bien(e:Event) { xmlLoader.addEventListener(Event.COMPLETE, loadXML); req=new URLRequest(file.name); xmlLoader.load(req); } public function loadXML(e:Event) { xml=new XML(e.target.data); //xml.name=file.name; trace(xml); } } } when I open a xml file that isnt it the same directory as the swf, it gives me an unfound file error. is there anything I can do? cause for example for mp3 there is an especial class for loading the file, see http://www.flexiblefactory.co.uk/flexible/?p=46 thanks

  • using jQuery to load the body of another HTML document between entries

    - by justin hall
    I'm trying to use jQuery to load the body of another HTML document, which contains our AdSense banner. It should display under each blog entry when in list view. I'm able to get it to load text, even images, but not the banner; the banner is a small script. Here is the website we are working with: http://neverknowtech.com/data/ (that's a test page, and the 'entry' displayed there contains the intended body content) As you can see here the body code does include an ad, and the word 'Ad'. The word 'Ad' is shown correctly below the post (as it is in list view) but the script for the Google Ad doesn't seem to make it. Here is what we have in the footer currently (replace [ with < and ] with ): [script type="text/javascript"] var classSelector = ":nth-child(1n)"; if ($(".list-journal-entry-wrapper .journal-entry-wrapper").length ] 0) { $('.list-journal-entry-wrapper .journal-entry-wrapper' + classSelector).after('[div class="journal-list-ad-insert"][/div]'); $('.list-journal-entry-wrapper .journal-list-ad-insert').load("/data/journal-list-ad-insert.html .body"); } [/script] note: the nth-child is there for when they decide how frequently to place the ads.

  • Ajax -- re-load div on success.

    - by RPM
    I am trying to accomplish a "re-load." More specifically, I need to be able to refresh a portion of my page as a result of another successful ajax call. Moreover, I load my portion of the page via ajax which obtains it's content from an ajax post. The result is my content being displayed inside my portion precisely. I need this portion of the page refreshed after a successful ajax post. Here is some of the code: /* Ajax-- this part is loaded automatically, and I need it reloaded upon success of another ajax post. This data comes from the outcome of my other ajax function. */ $('#newCo').load('click', function() { $.ajax({ url: 'index.php?dkd432k=uBus/310/Indeed', dataType: 'json', success: function(json) { if (json['newCompare']) { $('#newCo .newResults').html(json['newCompare']); } } }); }); The next portion of code is responsible for posting the data of which I obtain in this above ajax function. function ZgHiapud (ofWhich) { $.ajax({ url: 'index.php?dkd432k=uBus/310/update', type: 'post', data: 'product_id=' + product_id, dataType: 'json', success: function(json) { $('.success, .warning, .attention, .information').remove(); if (json['success']) { $('.attention').fadeIn('slow'); $('#compare_total').html(json['total']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); } In the end, I need to obtain the data that I send to the server immediately upon success of the second ajax call. This data that is sent via the second ajax call needs to fire the first ajax call upon success.

  • LOAD DATA INFILE with variables

    - by Hasitha
    I was tring to use the LOAD DATA INFILE as a sotred procedure but it seems it cannot be done. Then i tried the usual way of embedding the code to the application itself like so, conn = new MySqlConnection(connStr); conn.Open(); MySqlCommand cmd = new MySqlCommand(); cmd = conn.CreateCommand(); string tableName = getTableName(serverName); string query = "LOAD DATA INFILE '" + fileName + "'INTO TABLE "+ tableName +" FIELDS TERMINATED BY '"+colSep+"' ENCLOSED BY '"+colEncap+"' ESCAPED BY '"+colEncap+"'LINES TERMINATED BY '"+colNewLine+"' ("+colUpFormat+");"; cmd.CommandText = query; cmd.ExecuteNonQuery(); conn.Close(); The generated query that gets saved in the string variable query is, LOAD DATA INFILE 'data_file.csv'INTO TABLE tbl_shadowserver_bot_geo FIELDS TERMINATED BY ',' ENCLOSED BY '"' ESCAPED BY '"'LINES TERMINATED BY '\n' (timestamp,ip,port,asn,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy,url,agent,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy,@dummy); But now when i run the program it gives an error saying, MySQLException(0x80004005) Parameter @dummy must be defined first. I dont know how to get around this, but when i use the same query on mysql itself directly it works fine. PLEASE help me..thank you very much :)

  • How many users are sufficient to make a heavy load for web application

    - by galymzhan
    I have a web application, which has been suffering high load recent days. The application runs on single server which has 8-core Intel CPU and 4gb of RAM. Software: Drupal 5 (Apache 2, PHP5, MySQL5) running on Debian. After reaching 500 authenticated and 200 anonymous users (simultaneous), the application drastically decreases its performance up to total failure. The biggest load comes from authenticated users, who perform activities, causing insert/update/deletes on db. I think mysql is a bottleneck. Is it normal to slow down on such number of users? EDIT: I forgot to mention that I did some kind of profiling. I runned commands top, htop and they showed me that all memory was being used by MySQL! After some time MySQL starts to perform terribly slow, site goes down, and we have to restart/stop apache to reduce load. Administrators said that there was about 200 active mysql connections at that moment. The worst point is that we need to solve this ASAP, I can't do deep profiling analysis/code refactoring, so I'm considering 2 ways: my tables are MyIsam, I heard they use table-level locking which is very slow, is it right? could I change it to Innodb without worry? what if I take MySQL, and move it to dedicated machine with a lot of RAM?

  • How to merge multiple internet connections into one

    - by Luis Alvarado
    My PC has 2 wired cards. Both gigalan. It also has 2 wireless cards. One broadcom with proprietary drivers and ralink with open software (which works much better than broadcom). My cellphone can share its connection wirelessly to my PC. But I also have a wired connection. So I have multiple connections that I can use to have internet. How can I merge 2 or more connections together and balance them to enjoy one unified internet experience that it is the sum of all internet connections connected to it. For example if I have an internet connection that offers 1024KB/Sec and another that offers 512KB/Sec and one small one that offers 128KB/Sec, after load balancing and merging all connections, I could download at a speed of 1664KB/Sec using all 3 internet connections as one for example. This question has always intrigued me.

  • DB2 load partitioned data in parallel

    - by Erik Paulson
    I have a 10-node DB2 9.5 database, with raw data on each machine (ie node1:/scratch/data/dataset.1 node2:/scratch/data/dataset.2 ... node10:/scratch/data/dataset.10 There is no shared NFS mount - none of my machines could handle all of the datasets combined. each line of a dataset file is a long string of text, column delimited. The first column is the key. I don't know the hash function that DB2 will use, so dataset is not pre-partitioned. Short of renaming all of my files, is there any way to get DB2 to load them all in parallel? I'm trying to do something like load from '/scratch/data/dataset' of del modified by coldel| fastparse messages /dev/null replace into TESTDB.data_table part_file_location '/scratch/data'; but I have no idea how to suggest to db2 that it should look for dataset.1 on the first node, etc.

  • MySQL: Blank row in table after LOAD DATA INFILE

    - by Tom
    Hi, I'm uploading a large amount of data from a CSV (I'm doing it via MySQL Workbench): LOAD DATA INFILE 'C:/development/mydoc.csv' INTO TABLE mydatabase.mytable CHARACTER SET utf8 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r'; However, I'm noticing that it keeps adding an empty line full of nulls/zeros after the last record. I'm guessing it's because of the "LINES TERMINATED" command. However, I need that to load the data in correctly. Is there some way around this / some better SQL to avoid the blank row in the table? Thanks

  • LOAD DATA INFILE not working in mariadb

    - by Haseena
    Iam trying to migrate from mysql to mariadb. On this time I can face an issue with mariadb. When I can trying to load a data file into a table, it shows an error like : SQL Error (29): File 'C:/Documents and Settings/Administrator/Local Settings/Temp/SAMPLE/DATA_TEMP1351761841668/SampleFile0' not found (Errcode: 2) But the file already exists in the path.... Another one point is that the same command successfully works with MySQL. Is MariaDB has any permission issue? Login as Administrator. See below my query : load data infile "'C:/Documents and Settings/Administrator/Local Settings/Temp/SAMPLE/DATA_TEMP1351761841668/SampleFile0" into table SAMPLETABLE; When changing the path loke "C:/SampleFile0", its working properly. From Administrator folder it doesn't working. Can anyone help me in this regard??? Iam a newone in MariaDB.
