  • Parsing special strings within a text (eg. "%var%") ?

    - by RadiantHex
    Hi, I am supplying a Javascript function strings with commands (SVG path commands): eg. "move 10 10 line 50 50" move and line are commands numbers are x, y coordinates I would like to add special strings to these commands, that would instruct the function to use specific variables eg. "move %mouseX%+1 %mouseY%+1" where %mouseX% and %mouseY% would be the mouse x,y coordinates How can I parse and replace these?

  • Random loading swf files into main swf with countdown timer

    - by Plugger
    ok guys a question, can this be done or has it already been done, or can someone point me in the right direction (be aware i an a total newbie with action script) i have a main swf movie about 600px x 400 px what i want is this to run for say 30 seconds, then i want a countdown timer in the bottom corner for say 10 seconds, after this i want it to randomly load another swf file over the top of the original, and then the timer repeats for 10 seconds and repates the random loading of another swf file over the top etc, etc, etc so whats the best way around this

  • MySQL to fill in missing dates when using GROUP BY DATE(table.timestamp) without joining on temporar

    - by twmulloy
    Hello, after reading through a couple similar Qs/As I haven't quite found the solution I'm looking for. The table data I have is GROUP BY DATE(timestamp) and returning a count, example result: [timestamp] = 2010-05-12 20:18:36 [count] = 10 [timestamp] = 2010-05-14 10:10:10 [count] = 8 Without using a temporary table, or calendar table is there a way to fill in those missing dates? so that with the same table data would return (adding the bold row): [timestamp] = 2010-05-12 20:18:36 [count] = 10 [timestamp] = 2010-05-13 00:00:00 [count] = 0 [timestamp] = 2010-05-14 10:10:10 [count] = 8 Thanks!

  • Python multiprocessing global variable updates not returned to parent

    - by user1459256
    I am trying to return values from subprocesses but these values are unfortunately unpicklable. So I used global variables in threads module with success but have not been able to retrieve updates done in subprocesses when using multiprocessing module. I hope I'm missing something. The results printed at the end are always the same as initial values given the vars dataDV03 and dataDV04. The subprocesses are updating these global variables but these global variables remain unchanged in the parent. import multiprocessing # NOT ABLE to get python to return values in passed variables. ants = ['DV03', 'DV04'] dataDV03 = ['', ''] dataDV04 = {'driver': '', 'status': ''} def getDV03CclDrivers(lib): # call global variable global dataDV03 dataDV03[1] = 1 dataDV03[0] = 0 # eval( 'CCL.' + lib + '.' + lib + '( "DV03" )' ) these are unpicklable instantiations def getDV04CclDrivers(lib, dataDV04): # pass global variable dataDV04['driver'] = 0 # eval( 'CCL.' + lib + '.' + lib + '( "DV04" )' ) if __name__ == "__main__": jobs = [] if 'DV03' in ants: j = multiprocessing.Process(target=getDV03CclDrivers, args=('LORR',)) jobs.append(j) if 'DV04' in ants: j = multiprocessing.Process(target=getDV04CclDrivers, args=('LORR', dataDV04)) jobs.append(j) for j in jobs: j.start() for j in jobs: j.join() print 'Results:\n' print 'DV03', dataDV03 print 'DV04', dataDV04 I cannot post to my question so will try to edit the original.

  • When deinstalling Oracle falls PHP

    - by Adomas
    Hi, I have a web on php5, iis6, and Oracle on windows server 2003. I had Oracle 10.2.0.1.0 and deinstalled it. After that I installed earlier version (10.1.0) for cloning DB purposes, php doesn't work. As I understand it failes because of oci8.dll, but can't find the real problem. Please, help.

  • form a number using consecutive numbers

    - by Mahesh
    Hi, I was puzzled with one of the question in Microsoft interview which is as given below: A function should accept a range( 3 - 21 ) and it should print all the consecutive numbers combination's to form each number as given below: 3=1+2 5=2+3 6=1+2+3 7=3+4 9=4+5 10=1+2+3+4 11=5+6 13=6+7 15=1+2+3+4+5 17=7+8 19=8+9 21=10+11 21=1+2+3+4+5+6 could you please help me in forming this sequence in C#?

  • c#: Clean way to fit a collection into a multidimensional array?

    - by Rosarch
    I have an ICollection<MapNode>. Each MapNode has a Position attribute, which is a Point. I want to sort these points first by Y value, then by X value, and put them in a multidimensional array (MapNode[,]). The collection would look something like this: (30, 20) (20, 20) (20, 30) (30, 10) (30, 30) (20, 10) And the final product: (20, 10) (20, 20) (20, 30) (30, 10) (30, 20) (30, 30) Here is the code I have come up with to do it. Is this hideously unreadable? I feel like it's more hacky than it needs to be. private Map createWorldPathNodes() { ICollection<MapNode> points = new HashSet<MapNode>(); Rectangle worldBounds = WorldQueryUtils.WorldBounds(); for (float x = worldBounds.Left; x < worldBounds.Right; x += PATH_NODE_CHUNK_SIZE) { for (float y = worldBounds.Y; y > worldBounds.Height; y -= PATH_NODE_CHUNK_SIZE) { // default is that everywhere is navigable; // a different function is responsible for determining the real value points.Add(new MapNode(true, new Point((int)x, (int)y))); } } int distinctXValues = points.Select(node => node.Position.X).Distinct().Count(); int distinctYValues = points.Select(node => node.Position.Y).Distinct().Count(); IList<MapNode[]> mapNodeRowsToAdd = new List<MapNode[]>(); while (points.Count > 0) // every iteration will take a row out of points { // get all the nodes with the greatest Y value currently in the collection int currentMaxY = points.Select(node => node.Position.Y).Max(); ICollection<MapNode> ythRow = points.Where(node => node.Position.Y == currentMaxY).ToList(); // remove these nodes from the pool we're picking from points = points.Where(node => ! ythRow.Contains(node)).ToList(); // ToList() is just so it is still a collection // put the nodes with max y value in the array, sorting by X value mapNodeRowsToAdd.Add(ythRow.OrderByDescending(node => node.Position.X).ToArray()); } MapNode[,] mapNodes = new MapNode[distinctXValues, distinctYValues]; int xValuesAdded = 0; int yValuesAdded = 0; foreach (MapNode[] mapNodeRow in mapNodeRowsToAdd) { xValuesAdded = 0; foreach (MapNode node in mapNodeRow) { // [y, x] may seem backwards, but mapNodes[y] == the yth row mapNodes[yValuesAdded, xValuesAdded] = node; xValuesAdded++; } yValuesAdded++; } return pathNodes; } The above function seems to work pretty well, but it hasn't been subjected to bulletproof testing yet.

  • Why do I get rows of zeros in my 2D fft?

    - by Nicholas Pringle
    I am trying to replicate the results from a paper. "Two-dimensional Fourier Transform (2D-FT) in space and time along sections of constant latitude (east-west) and longitude (north-south) were used to characterize the spectrum of the simulated flux variability south of 40degS." - Lenton et al(2006) The figures published show "the log of the variance of the 2D-FT". I have tried to create an array consisting of the seasonal cycle of similar data as well as the noise. I have defined the noise as the original array minus the signal array. Here is the code that I used to plot the 2D-FT of the signal array averaged in latitude: import numpy as np from numpy import ma from matplotlib import pyplot as plt from Scientific.IO.NetCDF import NetCDFFile ### input directory indir = '/home/nicholas/data/' ### get the flux data which is in ### [time(5day ave for 10 years),latitude,longitude] nc = NetCDFFile(indir + 'CFLX_2000_2009.nc','r') cflux_southern_ocean = nc.variables['Cflx'][:,10:50,:] cflux_southern_ocean = ma.masked_values(cflux_southern_ocean,1e+20) # mask land nc.close() cflux = cflux_southern_ocean*1e08 # change units of data from mmol/m^2/s ### create an array that consists of the seasonal signal fro each pixel year_stack = np.split(cflux, 10, axis=0) year_stack = np.array(year_stack) signal_array = np.tile(np.mean(year_stack, axis=0), (10, 1, 1)) signal_array = ma.masked_where(signal_array > 1e20, signal_array) # need to mask ### average the array over latitude(or longitude) signal_time_lon = ma.mean(signal_array, axis=1) ### do a 2D Fourier Transform of the time/space image ft = np.fft.fft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log(mgft) log_mgft= np.log(mgft) Every second row of the ft consists completely of zeros. Why is this? Would it be acceptable to add a randomly small number to the signal to avoid this. signal_time_lon = signal_time_lon + np.random.randint(0,9,size=(730, 182))*1e-05 EDIT: Adding images and clarify meaning The output of rfft2 still appears to be a complex array. Using fftshift shifts the edges of the image to the centre; I still have a power spectrum regardless. I expect that the reason that I get rows of zeros is that I have re-created the timeseries for each pixel. The ft[0, 0] pixel contains the mean of the signal. So the ft[1, 0] corresponds to a sinusoid with one cycle over the entire signal in the rows of the starting image. Here are is the starting image using following code: plt.pcolormesh(signal_time_lon); plt.colorbar(); plt.axis('tight') Here is result using following code: ft = np.fft.rfft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log1p(mgft) plt.pcolormesh(log_ps); plt.colorbar(); plt.axis('tight') It may not be clear in the image but it is only every second row that contains completely zeros. Every tenth pixel (log_ps[10, 0]) is a high value. The other pixels (log_ps[2, 0], log_ps[4, 0] etc) have very low values.

  • Most efficient way to search the last x lines of a file in python

    - by Harley
    I have a file and I don't know how big it's going to be (it could be quite large, but the size will vary greatly). I want to search the last 10 lines or so to see if any of them match a string. I need to do this as quickly and efficiently as possible and was wondering if there's anything better than: s = "foo" last_bit = fileObj.readlines()[-10:] for line in last_bit: if line == s: print "FOUND"

  • DataAnnotation attributes buddy class strangeness - ASP.NET MVC

    - by JK
    Given this POCO class that was automatically generated by an EntityFramework T4 template (has not and can not be manually edited in any way): public partial class Customer { [Required] [StringLength(20, ErrorMessage = "Customer Number - Please enter no more than 20 characters.")] [DisplayName("Customer Number")] public virtual string CustomerNumber { get;set; } [Required] [StringLength(10, ErrorMessage = "ACNumber - Please enter no more than 10 characters.")] [DisplayName("ACNumber")] public virtual string ACNumber{ get;set; } } Note that "ACNumber" is a badly named database field, so the autogenerator is unable to generate the correct display name and error message which should be "Account Number". So we manually create this buddy class to add custom attributes that could not be automatically generated: [MetadataType(typeof(CustomerAnnotations))] public partial class Customer { } public class CustomerAnnotations { [NumberCode] // This line does not work public virtual string CustomerNumber { get;set; } [StringLength(10, ErrorMessage = "Account Number - Please enter no more than 10 characters.")] [DisplayName("Account Number")] public virtual string ACNumber { get;set; } } Where [NumberCode] is a simple regex based attribute that allows only digits and hyphens: [AttributeUsage(AttributeTargets.Property)] public class NumberCodeAttribute: RegularExpressionAttribute { private const string REGX = @"^[0-9-]+$"; public NumberCodeAttribute() : base(REGX) { } } NOW, when I load the page, the DisplayName attribute works correctly - it shows the display name from the buddy class not the generated class. The StringLength attribute does not work correctly - it shows the error message from the generated class ("ACNumber" instead of "Account Number"). BUT the [NumberCode] attribute in the buddy class does not even get applied to the AccountNumber property: foreach (ValidationAttribute attrib in prop.Attributes.OfType<ValidationAttribute>()) { // This collection correctly contains all the [Required], [StringLength] attributes // BUT does not contain the [NumberCode] attribute ApplyValidation(generator, attrib); } Why does the prop.Attributes.OfType<ValidationAttribute>() collection not contain the [NumberCode] attribute? NumberCode inherits RegularExpressionAttribute which inherits ValidationAttribute so it should be there. If I manually move the [NumberCode] attribute to the autogenerated class, then it is included in the prop.Attributes.OfType<ValidationAttribute>() collection. So what I don't understand is why this particular attribute does not work in when in the buddy class, when other attributes in the buddy class do work. And why this attribute works in the autogenerated class, but not in the buddy. Any ideas? Also why does DisplayName get overriden by the buddy, when StringLength does not?
