  • split a string into a key => value array in php

    - by andy-score
    +2-1+18*+7-21+3*-4-5+6x29 The above string is an example of the kind of string I'm trying to split into either a key = value array or something similar. The numbers represent the id of a class and -,+ and x represent the state of the class (minimised, expanded or hidden), the * represents a column break. I can split this into the columns easily using explode which gives and array with 3 $key = $value associations. eg. $column_layout = array( [0] => '+2-1+18' , [1] => '+7-21+3' , [2] => '-4-5+6x29' ) I then need to split this into the various classes from there, keeping the status and id together. eg. $column1 = array( '+' => 2 , '-' => 1 , '+' => 18 ) ... or $column1 = array( array( '+' , 2 ) , array( '-' , 1 ) , array( '+' , 18 ) ) ... I can't quite get my head round this and what the best way to do it is, so any help would be much appreciated.

  • Android game engine for 2d and 3d games?

    - by javame_android
    Hi, There is a library called cocos-2d for iphone. There are number of games developed with that nowadays. Also, there is cocos-2d library available for Android too. I just wanted to know if that is also as stable as iphone one or its still not stable to be used in development. Also, is there any other game engine available for Android? The ones that I know is AndEngine. Which one is better for development? If not both then will it better to develop using core Android API rather than using any game engine.

  • How can I start with <a href=" and have an array element here then end with </a>?

    - by Noor
    The thing im trying to do right now is pulling in multiple links from a textarea, We can pretend that a user inputs c:\pics\img01.jpg and in the next row he'll have the next imglink. I want to pull those links, I allready have the code for that: var entered = $('#filedir').val(); var lines = entered.split(/\r\n/); var opttext = ""; for(var i=0;i<lines.length;i++) { opttext += '< img src="' + lines[i] + '">< /img>'; } ? the problem is in the output which is: < img src="file:///C:/pics/img01.jpgc:/pics/img02.jpg">< /img> There should be two < img> elements.. Where am I going wrong? I've been at it for a bit over 2 hours now..

  • Selecting value from array results

    - by Swodahs
    Being new to learning PHP I am having trouble with understanding how to select/echo/extract a value from array result a API script returns. Using the standard: echo "<pre>"; print_r($ups_rates->rates); echo "</pre>"; The results returned look like this: Array ( [0] => Array ( [code] => 03 [cost] => 19.58 [desc] => UPS Ground ) [1] => Array ( [code] => 12 [cost] => 41.69 [desc] => UPS 3 Day Select ) [2] => Array ( [code] => 02 [cost] => 59.90 [desc] => UPS 2nd Day Air ) ) If I am only needing to work with the values of the first array result: Code 3, 19.58, UPS Ground --- what is the correct way to echo one or more of those values? I thought: $test = $ups_rates[0][cost]; echo $test; This is obviously wrong and my lack of understanding the array results isn't improving, can someone please show me how I would echo an individual value of the returned array and/or assign it to a variable to echo the normal way?

  • Java - Tile engine changing number in array not changing texture

    - by Corey
    I draw my map from a txt file. Would I have to write to the text file to notice the changes I made? Right now it changes the number in the array but the tile texture doesn't change.

Nothing works now. Where is the mistake?

  • Handy Javascript array Extensions &ndash; distinct()

    - by Liam McLennan
    The following code adds a method to javascript arrays that returns a distinct list of values. Array.prototype.distinct = function() { var derivedArray = []; for (var i = 0; i < this.length; i += 1) { if (!derivedArray.contains(this[i])) { derivedArray.push(this[i]) } } return derivedArray; }; and to demonstrate: alert([1,1,1,2,2,22,3,4,5,6,7,5,4].distinct().join(',')); This produces 1,2,22,3,4,5,6,7

  • Unable to Mount Seagate Array from Iomega

    - by GE Cardiff
    I am new to Ubuntu so please be kind! My (Windows based) Iomega Storcentre ix2-200 stopped working, with all my business data upon it. Iomega helpfully told me that I should get Fedora, remove the Seagate hard drives and recover the information by connecting via a USB / SATA cable. First I could not get Fedora to load (due to it needing an Internet connection before loading complete) so I got Ubuntu - much easier to load. Software seems fine, and in "Computer" there is an "Array" icon - this is clearly the Seagate hard drive I have connected. It will not, however, Mount. "Unable to mount location, can't mount file". Any help gratefully received! As a slight aside, I can't seem to find "terminal" in this version of Ubuntu?

  • Determining Whether a String Is Contained Within a String Array (Case Insensitive)

    About once every couple of months I need to write a bit of code that does one thing if a particular string is found within an array of strings and something else if it is not ignoring differences in case. For whatever reason, I never seem to remember the code snippet to accomplish this, so after spending 10 minutes of research today I thought I'd write it down here in an effort to help commit it to memory or, at the very least, serve as a quick place to find the answer when the need arises again.So without further adieu, here it is:Visual Basic Version:If stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase) Then ... Else ... End IfC# Version:if (stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase)) ... else ...Without the StringComparer.OrdinalIgnoreCase the search will be case-sensitive.

  • Removing mdadm array and converting to regular disks while preserving data

    - by Jeffrey Kevin Pry
    I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

  • Comparison between a value with static type Array and a possibly unrelated type Class

    - by Kaoru
    I got this error: Comparison between a value with static type Array and a possibly unrelated type Class. After i modify the class to many classes (before that, everything is on 1 class (all of the functions)), but after i move everything to many classes (all the functions is not on 1 class), that error appear. How to solve this? I am using AS3 and as3isolib Library. Here is the code after i modify the function: if (Constant.dude.y < Constant._numY) { if (Constant.dude.sprites != marioBackClass) { Constant.dude.sprites = [marioBackClass]; Constant.dudeDir = "Up"; } } Here is the code before i change the function to many classes: if (dude.y < ._numY) { if (dude.sprites.toString() != marioBackClass.toString()) { dude.sprites = [marioBackClass]; dudeDir = "Up"; } }

  • Channel 9 Interview: Array and Collection Initializers in Visual Basic 2010 (Beth Massi, Spotty Bowl

    Ive written about collection initializers on my blog before, but I thought Id catch up with the VB Team to tell me more about how they really work. In this interview Spotty Bowles, a tester on the VB Compiler team, shows us a couple of new language features: Array and Collection Initializers. He gives us insight into how they are implemented in the compiler and best practices on how to use them in our code. Additionally, he discusses how to extend Collection Initializers with your own extension...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Interpolating 2d data that is piecewise constant on faces

    - by celil
    I have an irregular mesh which is described by two variables - a faces array that stores the indices of the vertices that constitute each face, and a verts array that stores the coordinates of each vertex. I also have a function that is assumed to be piecewise constant over each face, and it is stored in the form of an array of values per face. I am looking for a way to construct a function f from this data. Something along the following lines: faces = [[0,1,2], [1,2,3], [2,3,4] ...] verts = [[0,0], [0,1], [1,0], [1,1],....] vals = [0.0, 1.0, 0.5, 3.0,....] f = interpolate(faces, verts, vals) f(0.2, 0.2) = 0.0 # point inside face [0,1,2] f(0.6, 0.6) = 1.0 # point inside face [1,2,3] The manual way of evaluating f(x,y) would be to find the corresponding face that the point x,y lies in, and return the value that is stored in that face. Is there a function that already implements this in scipy (or in matlab)?

  • computing z-scores for 2D matrices in scipy/numpy in Python

    - by user248237
    How can I compute the z-score for matrices in Python? Suppose I have the array: a = array([[ 1, 2, 3], [ 30, 35, 36], [2000, 6000, 8000]]) and I want to compute the z-score for each row. The solution I came up with is: array([zs(item) for item in a]) where zs is in scipy.stats.stats. Is there a better built-in vectorized way to do this? Also, is it always good to z-score numbers before using hierarchical clustering with euclidean or seuclidean distance? Can anyone discuss the relative advantages/disadvantages? thanks.

  • how to initialize a 2d array in perl

    How do I initialize a 2d array in perl? I am trying the following code: 0 use strict; 10 my @frame_events = (((1) x 10), ((1) x 10)); 20 print "$frame_events[1][1]\n"; but it gives the following error: Can't use string ("1") as an ARRAY ref while "strict refs" in use at ./dyn_pf.pl line 20. This syntax only seems to initialize a 1d array as print "$frame_events[1]\n" works. Though perl doesn't give any error during the assignment.

  • 2D pixel array rotation and scaling

    - by Betamoo
    Hi I am working on C# program to process images ( given as int[,] ).. So I have 2D array of pixels, and I need to rotate them around a point, then scale them down to fit the original array.. I already found articles about using matrix to transform to a point and rotate then transform back.. What remains is to scale the resultant image to fit an array of original size.. How that can be done? (preferably with 2 equations one for x and one for y ) Thanks in advance

  • Build a RAID-5 USB Array or NAS?

    - by TK Kocheran
    I'm looking to build a RAID-5 or RAID-6 hard disk array to be used as a centralized backup location for my home network. I have a lot of 4-8GB DVD ISO files which I intend to serve over the network to my TV using DLNA or something similar. I need decent write times, fast read times, and preferably a way to connect this array to my network router over USB. I'll probably be using ext3/4 on it (I'd use btrfs if my router supported it :-[). Is there a way to build a RAID array that is accessible over USB? I'm kind of new to this and most guides assume you're running a RAID array inside your machine. I need at least 5TB of space, and I need redundancy, so I prefer RAID-6. How can I go about accomplishing this?

  • Resizing RAID 1 Array on Dell PowerEdge with Perc 4/Di & Windows SBS 2003

    - by Scott McKinney
    I have a Dell PowerEdge 2600 with Perc 4/Di RAID card and Windows SBS 2003 installed. The original system drive was a set of 17GB drives in a RAID 1 array. Over the years, these drives have failed (individually) and been replaced by a set of 73GB drives, but the RAID array is still 17GB in size. Is there a safe procedure to resize the RAID 1 array to use the entire 73GB without destroying/corrupting the data on the array? The Perc documentation mentions a Reconstruct option with Online Capacity Expansion, but is a woefully short on the exact details. Has anyone performed this procedure successfully (or unsuccessfully)? What were the steps? Are there any gotchas I should watch out for?

  • converting 0+1 raid array to 0

    - by werelord
    I'm currently running raid 0+1; four 500 GB drives in the array.. I'm looking at migrating the array from 0+1 (Stripe+Mirror) to 0 only (stripe).. The goal is to remove the hard drives from the array in order to put them in the newly purchased Drobo, then copy the data from the remaining striped raid to the said Drobo.. Is it sufficient to just remove the drives themselves and change the raid configuration within the nvidia raid config?? Or is there something more that needs to be done?? Does the order matter (i.e. removing drives first or changing the raid configuration??) Is it possible to migrate the array this way without having any loss of data? I'm wary about burning all that data to DVDs (few hundred GB worth) to back it up.. Any other advice from people that may have done this (or have other insight) would be helpful as well..

  • Replacing a non-failing drive in a RAID-0 array

    - by TallFurryMan
    I have a Windows 7 machine booting on a RAID-0 pair of 500GB disks, controlled by an ICH9R. One of those was indicating an end-To-end SMART failure, so I added a spare disk as a temporary workaround, before receiving another to replace the failing one. The RAID-0 rebuilt on the spare and dropped the failing one from the array, as expected. Now that I received the new drive, what are my options to reintegrate it in the array? My first thought was to simply clone the temporary disk to the new one while the array is offline, but shouldn't there be a way to force a second rebuild, just as if the temporary drive had a warning, and drop that temporary from the array?
