  • Kohana 3 Auto loading Models

    - by pigfox
    I'm attempting to use a Model but I get a fatal error so I assume it doesn't autoload properly. ErrorException [ Fatal Error ]: Class 'Properties_Model' not found The offending controller line: $properties = new Properties_Model; The model: class Properties_Model extends Model { public function _construct() { parent::_construct(); } } I also put the class in three different locations hoping one would work, all there failed. They are: application/classes/model application/model application/models What am I missing?

  • Can't get iptables firewall working correctly

    - by Jay
    I'm setting up a new Centos 5.6 system and can't get my iptables firewall to work correctly. it won't let me use SSH through it. I'm new to Centos but not to Linux or iptables. I've been removing things until I have isolated the problem. I set up the firewall with a default ACCEPT rule for the INPUT chain. I can connect through to the server fine. If I change the command to only allow traffic from the interface connecting to my trusted network it stops working. Working: iptables -A INPUT -s 0/0 -d 0/0 -j ACCEPT Failing: iptables -A INPUT -i eth0 -s 0/0 -d 0/0 -j ACCEPT I've double checked the ip address I'm using corresponds to eth0 using ifconfig. Any ideas where I went wrong?

  • Project Euler 9 Understanding

    - by DMan
    This question states: A Pythagorean triplet is a set of three natural numbers, a b c, for which, a2 + b2 = c2 For example, 32 + 42 = 9 + 16 = 25 = 52. There exists exactly one Pythagorean triplet for which a + b + c = 1000. Find the product abc. I'm not sure what's it trying to ask you. Are we trying to find a^2+b^2=c^2 and then plug those numbers into a+b+c=1000?

  • Help needed in database design for application of Timetable Generation

    - by Himadri
    I am planning for an application of time-table generation. I wanted the data such as standardname, teachername, standard wise subjects and also relate the corresponding teacher with the subject and standard. I had think like, StandardMaster(stdid,stdname) TeacherMaster(teacherid,teachername) SubjectMaster(subid,subname,stdid) What more I need? Any corrections needed in these three tables?

  • C# as a very first language?

    - by I00I
    Is it possible to learn C# as your first computer language without any knowledge of the other three languages it combines? I learned objective-c without knowing c first, but assuming I know nothing of C# or any other language is it possible to learn as a first language?

  • CSF Unresolved issue

    - by josephmarhee
    I began receiving service failures for CSF/LFD once the limit was reached in iptables preventing the service from working properly. I flushed all iptables rules, and redid by rules using CIDR rather than the individual IPs that were listed and the issue persists. Error: The VPS iptables rule limit (numiptent) is too low (1527/1536) - stopping firewall to prevent iptables blocking all connections, at line 1459 This is after restarting CSF, which gave me: You have an unresolved error when starting csf. You need to restart csf successfully to remove this warning CSF still seems to be trying to enforce rules that no longer exists (lists entire chains upon trying to be restarted,only to fail with that error). Any idea of what's going on?

  • Set an Excel cell's color based on multiple other cells' colors

    - by Lord Torgamus
    I have an Excel 2007 spreadsheet for a list of products and a bunch of factors to rate each one on, and I'm using Conditional Formatting to set the color of the cells in the individual attribute columns. It looks something like this: I want to fill in the rating column for each item with a color, based on the color ratings of its individual attributes. Examples of ways to determine this: the color of the category in which the item scored worst the statistical mode of the category colors the average of the category ratings, where each color is assigned a numerical value How can I implement any or all of the above rules? (I'm really just asking for a quick overview of the relevant Excel feature; I don't need step-by-step instructions for each rule.)

  • How to choose between UUIDs, autoincrement/sequence keys and sequence tables for database primary keys?

    - by Tim
    I'm looking at the pros and cons of these three primary methods of coming up with primary keys for database rows. So assuming I am using a database that supports more than one of these methods, is there a simple heuristic to determine what the best option would be for me? How do considerations such a distributed/multiple masters, performance requirements, ORM use, security and testing have on the choice? Any unexpected drawbacks that one might run into?

  • Filtering python string through external program

    - by Peter
    What's the cleanest way of filtering a Python string through an external program? In particular, how do you write the following function? def filter_through(s, ext_cmd): # Filters string s through ext_cmd, and returns the result. # Example usage: # filter a multiline string through tac to reverse the order. filter_through("one\ntwo\nthree\n", "tac") # => returns "three\ntwo\none\n" Note: the example is only that - I realize there are much better ways of reversing lines in python.

  • Simulating inheritance with WF 4.0

    - by pablocastilla
    Hello everyone, I would like to achieve the following: all the workflows created should have the same structure (validation, execution, save results), and all the developers should implement those three stages (maybe leaving it empty). Similar to inheritance with abstract methods. Any ideas?

  • PHP preg_replace - Very quick question

    - by RC
    Masters of regular expressions, please help! See this string: $string = "http://www.url.com/?fieldA=123&fieldB=456&fieldC=789"; Assuming "fieldB" always has a positive non-decimal numerical value (but not necessarily three digits long), what preg_replace command do I need to remove it completely, such that the string will then read: $string = "http://www.url.com/?fieldA=123&fieldC=789"; Thanks!

My problem is all three sprite1, sprite2, remaining screen should have independent touches. But my program is taking all the touches as same. How can I make them as what I needed ? Thank You.

  • Are comonads a good fit for modeling the Wumpus world?

    - by Tim Stewart
    I'm trying to find some practical applications of a comonad and I thought I'd try to see if I could represent the classical Wumpus world as a comonad. I'd like to use this code to allow the Wumpus to move left and right through the world and clean up dirty tiles and avoid pits. It seems that the only comonad function that's useful is extract (to get the current tile) and that moving around and cleaning tiles would not use be able to make use of extend or duplicate. I'm not sure comonads are a good fit but I've seen a talk (Dominic Orchard: A Notation for Comonads) where comonads were used to model a cursor in a two-dimensional matrix. If a comonad is a good way of representing the Wumpus world, could you please show where my code is wrong? If it's wrong, could you please suggest a simple application of comonads? module Wumpus where -- Incomplete model of a world inhabited by a Wumpus who likes a nice -- tidy world but does not like falling in pits. import Control.Comonad -- The Wumpus world is made up of tiles that can be in one of three -- states. data Tile = Clean | Dirty | Pit deriving (Show, Eq) -- The Wumpus world is a one dimensional array partitioned into three -- values: the tiles to the left of the Wumpus, the tile occupied by -- the Wumpus, and the tiles to the right of the Wumpus. data World a = World [a] a [a] deriving (Show, Eq) -- Applies a function to every tile in the world instance Functor World where fmap f (World as b cs) = World (fmap f as) (f b) (fmap f cs) -- The Wumpus world is a Comonad instance Comonad World where -- get the part of the world the Wumpus currently occupies extract (World _ b _) = b -- not sure what this means in the Wumpus world. This type checks -- but does not make sense to me. extend f w@(World as b cs) = World (map world as) (f w) (map world cs) where world v = f (World [] v []) -- returns a world in which the Wumpus has either 1) moved one tile to -- the left or 2) stayed in the same place if the Wumpus could not move -- to the left. moveLeft :: World a -> World a moveLeft w@(World [] _ _) = w moveLeft (World as b cs) = World (init as) (last as) (b:cs) -- returns a world in which the Wumpus has either 1) moved one tile to -- the right or 2) stayed in the same place if the Wumpus could not move -- to the right. moveRight :: World a -> World a moveRight w@(World _ _ []) = w moveRight (World as b cs) = World (as ++ [b]) (head cs) (tail cs) initWorld = World [Dirty, Clean, Dirty] Dirty [Clean, Dirty, Pit] -- cleans the current tile cleanTile :: Tile -> Tile cleanTile Dirty = Clean cleanTile t = t Thanks!

  • cPanel IPTables custom rules

    - by James Haigh
    Hi, I'm trying to allow a host access to port 3306 by IP. I've added the rule and ran an iptables-save and also service iptables save. These commands show as "OK" with no reported errors. And this works absolutely fine. Now, the server hasn't been restarted at all since I've been having this problem, but every day when I start developing on the server that needs mySQL access, it reports that the connection is refused. Back on the mySQL server, all I need to do is service iptables restart and everything then works as normal. The mySQL server is a CentOS cPanel VPS running on OpenVZ. Anyone know how I can make these rules persist? Is it something cPanel is doing overnight that is messing with my config? Thanks.
