  • Perl, regex, extract data from a line

    - by perlnoob
    Im trying to extract part of a line with perl use strict; use warnings; # Set path for my.txt and extract datadir my @myfile = "C:\backups\MySQL\my.txt"; my @datadir = ""; open READMYFILE, @myfile or die "Error, my.txt not found.\n"; while (<READMYFILE>) { # Read file and extract DataDir path if (/C:\backups/gi) { push @datadir, $_; } } # ensure the path was found print @datadir . " \n"; Basically at first im trying to set the location of the my.txt file. Next im trying to read it and pull part of the line with regex. The error Im getting is: Unrecognized escape \m passed through at 1130.pl line 17. I took a look at http://stackoverflow.com/questions/1040657/how-can-i-grab-multiple-lines-after-a-matching-line-in-perl to get an idea of how to read a file and match a line within it, however im not 100% sure I'm doing this right or in the best way. I also seem to produce the error: Error, my.txt not found. But the file does exist in the folder C:\backups\MySQL\

  • iPhone: variable type returned by yajl

    - by Luc
    Hello, I'm quite new to iphone programming and I want to do the following stuff: get data from a JSON REST web server parse the received data using YAJL Draw a graph with those data using core-plot So, 1th item is fine, I use ASIHttpRequest which runs as espected 3rd is almost fine (I still have to learn how to tune core-plot). The problem I have is regarding 2nd item. I use YAJL as it seems to be the faster parser, so why not give it a try :) Here is the part of code that gets the data from the server and parse them: // Get server data response_data = [request responseData]; // Parse JSON received self.arrayFromData = [response_data yajl_JSON]; NSLog(@"Array from data: %@", self.arrayFromData); The parsing works quite well in fact, the NSLog output is something like: 2010-06-14 17:56:35.375 TEST_APP[3733:207] Array from data : { data = ( { val = 1317; date = "2010-06-10T15:50:01+02:00"; }, { val = 1573; date = "2010-06-10T16:20:01+02:00"; }, ........ { val = 840; date = "2010-06-11T14:50:01+02:00"; }, { val = 1265; date = "2010-06-11T15:20:01+02:00"; } ); from = "2010-06-10T15:50:01+02:00"; to = "2010-06-11T15:20:01+02:00"; max = "2590"; } According to th yajl-objc explanations http://github.com/gabriel/yajl-objc, the parsing returns a NSArray... The thing is... I do not know how to get all the values from it as for me it looks more like a NSDictionary than a NSArray... Could you please help ? Thanks a lot, Luc edit1: it happens that this object is actually a NSCFDictionary (!), I am still not able to get value from it, when I try the objectFromKey method (that should work on a Dictionary, no ?) it fails.

  • IList<Item> Collection Class accessing database

    - by Mike
    Hi, I have a database with Users. Users have Items. These Items can change actively. How do you access the items in a collection type format? For the user, I fill all the user properties at the time of instantiation. If I load the user's items at the time of the instantiation, and the items change, they will have old data. I was thinking, maybe I need an ItemCollection class and have that a field/property apart of the user class, that way to traverse all the user's items I could use a foreach loop. So, my question is, what is the best practice/best way of accessing the items from a database using some sort of collection? On accessing the particular Item, it needs to get the latest database information, and when the user does do a foreach loop, the latest item information must be available. I.e. What I'm trying to do Console.WriteLine(User.Items[3].ID); returns 5. //this updates the item information and saves it to the database. User.Items[3].ID = 13; //Add a new item to the database. User.Items.Add(new Item { id = 17}); foreach (Item item in User.Items) { //this would traverse all items in the database. //not some cached copy at the time of instantiation of the user. }

  • Reading a large file into Perl array of arrays and manipulating the output for different purposes

    - by Brian D.
    Hello, I am relatively new to Perl and have only used it for converting small files into different formats and feeding data between programs. Now, I need to step it up a little. I have a file of DNA data that is 5,905 lines long, with 32 fields per line. The fields are not delimited by anything and vary in length within the line, but each field is the same size on all 5905 lines. I need each line fed into a separate array from the file, and each field within the line stored as its own variable. I am having no problems storing one line, but I am having difficulties storing each line successively through the entire file. This is how I separate the first line of the full array into individual variables: my $SampleID = substr("@HorseArray", 0, 7); my $PopulationID = substr("@HorseArray", 9, 4); my $Allele1A = substr("@HorseArray", 14, 3); my $Allele1B = substr("@HorseArray", 17, 3); my $Allele2A = substr("@HorseArray", 21, 3); my $Allele2B = substr("@HorseArray", 24, 3); ...etc. My issues are: 1) I need to store each of the 5905 lines as a separate array. 2) I need to be able to reference each line based on the sample ID, or a group of lines based on population ID and sort them. I can sort and manipulate the data fine once it is defined in variables, I am just having trouble constructing a multidimensional array with each of these fields so I can reference each line at will. Any help or direction is much appreciated. I've poured over the Q&A sections on here, but have not found the answer to my questions yet. Thanks!! -Brian

  • Get available screen area in autohotkey

    - by Herms
    I'm trying to write a few simple AutoHotkey scripts for moving windows around, and I'm having trouble getting the correct screen size values. I'm trying to get the size of the usable area on the screen (generally the full screen resolution minus the taskbar, and maybe any other docked windows like the sidebar in Vista). Neither of the methods I've found for getting the screen width seems to work. None of the 3 methods I found to get the screen size are giving me the right values. Here's the test script I'm using (running on XP with the taskbar on the bottom at its default size): #7:: WinMove A,,0,0,A_ScreenWidth,A_ScreenHeight return #8:: ;SM_CXMAXIMIZED and SM_CYMAXIMIZED SysGet, ScreenWidth, 61 SysGet, ScreenHeight, 62 WinMove A,,0,0,ScreenWidth,ScreenHeight return #9:: ;SM_CXFULLSCREEN and SM_CYFULLSCREEN SysGet, ScreenWidth, 16 SysGet, ScreenHeight, 17 WinMove A,,0,0,ScreenWidth,ScreenHeight return #7 causes the window to take up the entire resolution, so it overlaps the taskbar. #8 causes the width to be larger than the resolution (I see the window's right edge show up on my secondary monitor) and the height is slightly too large, so the window partially overlaps the taskbar area. Looks like this is correct except for not taking into account the window decorations at the edges. #9 seems to have the correct width, but the height is too short. It looks like it's subtracting the taskbar's height from the resolution's height, but then subtracting another 30 pixels from it. I could just use what I have in #9 and add 30 to the height I get, but that feels too much like a hack that would break in other configurations. It seems like there has to be a way to get the available screen size properly, but I can't find it in AutoHotkey. For reference, this seems to give me what I need in Java: Toolkit.getDefaultToolkit().getScreenSize();

  • Why should the "prime-based" hashcode implmentation be used instead of the "naive" one?

    - by Wilhelm
    I have seen that a prime number implmentation of the GetHashCode function is being recommend, for example here. However using the following code (in VB, sorry), it seems as if that implementation gives the same hash density as a "naive" xor implementation. If the density is the same, I would suppose there is the same probability of cllision in both implementations. Am I missing anything on why is the prime approach preferred? I am supossing that if the hash code is a byte I do not lose generality for the integer case. Sub Main() Dim XorHashes(255) As Integer Dim PrimeHashes(255) As Integer For i = 0 To 255 For j = 0 To 255 For k = 0 To 255 XorHashes(GetXorHash(i, j, k)) += 1 PrimeHashes(GetPrimeHash(i, j, k)) += 1 Next Next Next For i = 0 To 255 Console.WriteLine("{0}: {1}, {2}", i, XorHashes(i), PrimeHashes(i)) Next Console.ReadKey() End Sub Public Function GetXorHash(ByVal valueOne As Integer, ByVal valueTwo As Integer, ByVal valueThree As Integer) As Byte Return CByte((valueOne Xor valueTwo Xor valueThree) Mod 256) End Function Public Function GetPrimeHash(ByVal valueOne As Integer, ByVal valueTwo As Integer, ByVal valueThree As Integer) As Byte Dim TempHash = 17 TempHash = 31 * TempHash + valueOne TempHash = 31 * TempHash + valueTwo TempHash = 31 * TempHash + valueThree Return CByte(TempHash Mod 256) End Function

  • IntegrityError: foreign key violation upon delete

    - by Lukasz Korzybski
    I have Order and Shipment model. Shipment has a foreign key to Order. class Order(...): ... class Shipment() order = m.ForeignKey('Order') ... Now in one of my views I want do delete order object along with all related objects. So I invoke order.delete(). I have Django 1.0.4, PostgreSQL 8.4 and I use transaction middleware, so whole request is enclosed in single transaction. The problem is that upon order.delete() I get: ... File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 28, in _commit return self.connection.commit() IntegrityError: update or delete on table "main_order" violates foreign key constraint "main_shipment_order_id_fkey" on table "main_shipment" DETAIL: Key (id)=(45) is still referenced from table "main_shipment". I checked in connection.queries that proper queries are executed in proper order. First shipment is deleted, after that django executes delete on order row: {'time': '0.000', 'sql': 'DELETE FROM "main_shipment" WHERE "id" IN (17)'}, {'time': '0.000', 'sql': 'DELETE FROM "main_order" WHERE "id" IN (45)'} Foreign key have ON DELETE NO ACTION (default) and is initially deferred. I don't know why I get foreign key constraint violation. I also tried to register pre_delete signal and manually delete shipment objects before delete on order is called, but it resulted in the same error. I can change ON DELETE behaviour for this key in Postgres but it would be just a hack, I wonder if anyone has a better idea what's going on here. There is also a small detail, my Order model inherits from Cart model, so it actually doesn't have id field but cart_ptr_id and after DELETE on order is executed there is also DELETE on cart, but it seems unrelated? to the shipment-order problem so I simplified it in the example.

  • XmlHttpRequest in a bookmarklet returns empty responseText on GET?

    - by David Eyk
    I'm trying to build a javascript bookmarklet for a special URL shortening service we've built at http://esv.to for shortening scripture references (i.e. "Matthew 5" becomes "http://esv.to/Mt5". The bookmarklet is supposed to do a GET request to http://api.esv.to/Matthew+5, which returns a text/plain response of http://esv.to/Mt5. The code for the bookmarklet itself looks like this (expanded for readability): var body = document.getElementsByTagName('body')[0], script = document.createElement('script'); script.type = 'text/javascript'; script.src = 'http://esv.to/media/js/bookmarklet.js'; body.appendChild(script); void(0); The code from http://esv.to/media/js/bookmarklet.js looks like this: (function() { function shorten(ref, callback) { var url = "http://esv.to/api/" + escape(ref); var req = new XMLHttpRequest(); req.onreadystatechange = function shortenIt() { if ( this.readyState == 4 && this.status == 200 ) { callback(req.responseText); }; }; req.open( "GET", url ); req.send(); }; function doBookmarklet() { var ref = prompt("Enter a scripture reference or keyword search to link to:", "") shorten(ref, function (short) { prompt("Here is your shortened ESV URL:", short); }); }; doBookmarklet(); })(); When called from http://esv.to itself, the bookmarklet works correctly. But when used on another page, it does not. The strange thing is, when I watch the request from Firebug, the response is 200 OK, the browser downloads 17 bytes (the length of the returned string), but the response body is empty! No error is thrown, just an empty responseText on the XmlHttpRequest object. Now, according to http://stackoverflow.com/questions/664689/ajax-call-from-bookmarklet, GET shouldn't violate the same origin policy. Is this a bug? Is there a workaround?

  • C++ LPTSTR to int (but memory overwrite problem using atoi)

    - by Dexter
    I have the following code, m_edit is a MFC CEdit (I know I would never use MFC but project demanded it). It's a simple loop, that gets the text from a text edit, converts it to integer after getting the first line, then stores it in m_y vector. LPTSTR szTemp; vector<int> m_y; for(int i = 0; i < m_edit->GetLineCount(); i++){ szTemp = s_y.GetBuffer(0); m_edit->GetLine(i, szTemp); // get line text store in szTemp y = atoi(szTemp); m_y.push_back(y); szTemp = ""; y = 0; } IMPORTANT EXAMPLE: So let's say the CEdit has 6 numbers: 0 5 2 5 18 6 If you use Visual Studio's debugger you will notice an anomaly!! Here's what it shows: y = 0 y = 5 y = 2 y = 5 y = 18 y = 68 Do you see that? szTemp when inserted into atoi, it returns the number 6, but concatenates the 2nd digit of the last number!!! This is why I did szTemp = "";, but the problem persists. Also, let's say the last number was 17 (not 18), then this time debugger would say y = 67, so it is definitely this problem. However, Visual Studio debugger, when you hover over szTemp during this iteration, it says '6' <--- not '68' inside szTemp. So somehow atoi is ruining it. Am I suppose to concatenate a \0 into szTemp before putting it into atoi? How do I solve this easily?

  • Entity Framework and stored procedure returning temp table Issues

    - by kaplooeymom
    (Disclaimer - I'm not the database designer. I'm just the poor developer what has to make this work.) There are 17 (at the moment) tables with identical structure - name, address, phone number. Given a phone number, I have to check to see if there's a matching entry in any of the tables, then return that address. So, I created a view to get the list of tables (there's a ref table that holds that info), then I created a stored procedure to create a temp table, using cursors, check each table in the view for the phone number, using sql concatenation. If a record is found, insert it into the temp table. return the rows from the temp table. This all works in straight T-SQL. Now, I'm trying to use Entity Framework 4+ to call the stored procedure. But the function import interface won't generate columns. It says return type = none, and the LINQ code expects an int and won't compile. Any ideas on how to make this work? I know I can move the check tables part to code, if I absolutely have to, but I'd rather have the above method work.

  • Is Software Engineering Dead? [closed]

    - by nik
    Right from Jeff's blog: Software Engineering: Dead? I was utterly floored when I read this new IEEE article by Tom DeMarco (pdf). See if you can tell why. He quotes DeMarco, "I'm gradually coming to the conclusion that software engineering is an idea whose time has come and gone". Further, "What DeMarco seems to be saying -- and, at least, what I am definitely saying -- is that control is ultimately illusory on software development projects." I am writing these lines without context to invoke reading of the related subject. What are the views of the programming community here? I have started to realize that a community wiki is not getting the right amount of participation here. That is the reason I left this question out in the open, while still contemplating a change to CW. It was closed once, and I thought that was the end of it. But, now I see it was reopened and has more answers (all of which I have not yet read). However, I see a lot of CW requests and am forced to reconsider that. This is how I intend to make the CW decision here. There is a comment by Neil Butterworth requesting a CW at 12 upvotes -- "should be community wiki" There is a comment by Lance Roberts requesting no CW at 0 upvotes -- "+1 for not putting it in community wiki" The difference is 12 for a CW request at the moment If this difference becomes 5 more (that is 17), I'll move this question to CW, and it will not return back from there Of course, there is also a close vote at the moment; the question may be closed again.

  • git doesn't show where code was removed.

    - by Andrew Myers
    So I was tasked at replacing some dummy code that our project requires for historical compatibility reasons but has mysteriously dropped out sometime since the last release. Since disappearing code makes me nervous about what else might have gone missing but un-noticed I've been digging through the logs trying to find in what commit this handful of lines was removed. I've tried a number of things including "git log -S'add-visit-resource-pcf'", git blame, and even git bisect with a script that simply checks for the existence of the line but have been unable to pinpoint exactly where these lines were removed. I find this very perplexing, particularly since the last log entry (obtained by the above command) before my re-introduction of this code was someone else adding the code as well. commit 0b0556fa87ff80d0ffcc2b451cca1581289bbc3c Author: Andrew Date: Thu May 13 10:55:32 2010 -0400 Re-introduced add-visit-resource-pcf, see PR-65034. diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index f8e692d..a6f8d38 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -115,6 +115,7 @@ #:add-to-current-resource-pcf #:add-user-package-nickname #:add-value-criteria + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types commit 9fb10e25572c537076284a248be1fbf757c1a6e1 Author: Bob Date: Sun Jan 17 18:35:16 2010 -0500 update-defpackage for Spike 33.1 Delivery diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index 983666d..47f1a9a 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -118,6 +118,7 @@ #:add-user-package-nickname #:add-value-criteria #:add-vars-from-proposal + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types This is for one of our package definition files, but the relevant source file reflects something similar.

  • Using Custom MapType with Google Maps API

    - by Pat Long - Munkii Yebee
    I realise there are a couple of examples such as Maoki's Add Your Own Custom Map and Mike Williams' [link text][Google Maps API Tutorial] however I have looked at these and still end up with a Grey box. The API will not call my "getTileUrl" callback function. This is the javascript I am using var map = new GMap2(document.getElementById("map")); map.setUIToDefault(); var copyCollection = new GCopyrightCollection('Map Data:'); var copyright = new GCopyright(1, new GLatLngBounds(new GLatLng(-90, -180), new GLatLng(90, 180)), 0, "©2006 RunwayFinder.com"); copyCollection.addCopyright(copyright); var tilelayers = [new GTileLayer(copyCollection, 3, 11)]; tilelayers[0].getTileUrl = function (a, b) { var z = 17 - b; var f = "http://localhost:25213/test.jpg?x=" + a.x + "&y=" + a.y + "&zoom=" + z + "&width=100&height=100"; return f; }; var custommap = new GMapType(tilelayers, new GMercatorProjection(12), "Chart", { errorMessage: "No chart data available" }); map.addMapType(custommap); Can anyone see what it is i am doing wrong?

  • Downloading jQuery UI: Ok, so what part of this mess do I copy to the server?

    - by Martha
    From the "should be simple, but..." files: Trying to get started with jQuery UI. Went to the site, used their custom builder thingy to assemble the parts I need, made myself a custom theme using the Theme Roller, downloaded the zip file thus produced, unzipped it on my local drive. Ok, so I have 37 folders, 311 files, and a total of 2.4 MB. Ain't no way in hell all this is going on the server. What parts do I need to put there? 'css' 'custom-theme': jquery-ui-1.8.custom.css, 'images' subfolder with 12 .png images 'development-bundle' 'demos': demos.css, index.html, plus 18 subfolders, but I'm guessing "not needed" 'docs': 17 .html files, but again, I'm guessing "not needed" 'external': 4 .js files, one .css 'themes': 'base' and 'custom-theme' subfolders, each with 8 or 9 .css files and an 'images' subfolder with about a dozen images 'ui': 25 .js files, an 'i18n' subfolder with 53 .js files, and a 'minified' subfolder with 24 .js files 'js': jquery-1.4.2.min.js and jquery-ui-1.8.custom.min.js Also, the file structure. Our server is set up something like this: root admin (administrative tools) css forms (the gist of the site lives here) images include (asp code snippets that are used by multiple pages) js (just a few things right now, like an ancient wheezing spelling checker) As far as I can tell, the jQuery css files assume that (1) each theme is in its own folder, and (2) each folder has its own images subfolder. How can I convince it otherwise? i.e. put the necessary .js files in the 'js' folder, the .css files in the 'css' folder, and the images in the 'images' folder?

  • How to efficiently show many Images? (iPhone programming)

    - by Thomas
    In my application I needed something like a particle system so I did the following: While the application initializes I load a UIImage laserImage = [UIImage imageNamed:@"laser.png"]; UIImage *laserImage is declared in the Interface of my Controller. Now every time I need a new particle this code makes one: // add new Laserimage UIImageView *newLaser = [[UIImageView alloc] initWithImage:laserImage]; [newLaser setTag:[model.lasers count]-9]; [newLaser setBounds:CGRectMake(0, 0, 17, 1)]; [newLaser setOpaque:YES]; [self.view addSubview:newLaser]; [newLaser release]; Please notice that the images are only 17px * 1px small and model.lasers is a internal array to do all the calculating seperated from graphical output. So in my main drawing loop I set all the UIImageView's positions to the calculated positions in my model.lasers array: for (int i = 0; i < [model.lasers count]; i++) { [[self.view viewWithTag:i+10] setCenter:[[model.lasers objectAtIndex:i] pos]]; } I incremented the tags by 10 because the default is 0 and I don't want to move all the views with the default tag. So the animation looks fine with about 10 - 20 images but really gets slow when working with about 60 images. So my question is: Is there any way to optimize this without starting over in OpenGl ES? Thank you very much and sorry for my english! Greetings from Germany, Thomas

  • Total Order between !different! volatile variables?

    - by andreas
    Hi all, Consider the following Java code: volatile boolean v1 = false; volatile boolean v2 = false; //Thread A v1 = true; if (v2) System.out.println("v2 was true"); //Thread B v2 = true; if (v1) System.out.println("v1 was true"); If there was a globally visible total order for volatile accesses then at least one println would always be reached. Is that actually guaranteed by the Java Standard? Or is an execution like this possible: A: v1 = true; B: v2 = true; A: read v2 = false; B: read v1 = false; A: v2 = true becomes visible (after the if) B: v1 = true becomes visible (after the if) I could only find statements about accesses to the same volatile variable in the Standard (but I might be missing something). "A write to a volatile variable (§8.3.1.4) v synchronizes-with all subsequent reads of v by any thread (where subsequent is defined according to the synchronization order)." http://java.sun.com/docs/books/jls/third_edition/html/memory.html#17.4.4 Thanks!

  • With Go, how to append unknown number of byte into a vector and get a slice of bytes?

    - by Stephen Hsu
    I'm trying to encode a large number to a list of bytes(uint8 in Go). The number of bytes is unknown, so I'd like to use vector. But Go doesn't provide vector of byte, what can I do? And is it possible to get a slice of such a byte vector? I intends to implement data compression. Instead of store small and large number with the same number of bytes, I'm implements a variable bytes that uses less bytes with small number and more bytes with large number. My code can not compile, invalid type assertion: 1 package main 2 3 import ( 4 //"fmt" 5 "container/vector" 6 ) 7 8 func vbEncodeNumber(n uint) []byte{ 9 bytes := new(vector.Vector) 10 for { 11 bytes.Push(n % 128) 12 if n < 128 { 13 break 14 } 15 n /= 128 16 } 17 bytes.Set(bytes.Len()-1, bytes.Last().(byte)+byte(128)) 18 return bytes.Data().([]byte) // <- 19 } 20 21 func main() { vbEncodeNumber(10000) } I wish to writes a lot of such code into binary file, so I wish the func can return byte array. I haven't find a code example on vector.

  • concatenate string and running index into string within a loop

    - by user331706
    To use a given graphic package I need to define, book and fill histogram. How can I get the name of the histogram which is a string to concatenate with 2 integer as a string ( hts_i_j ) in 3 for loop instead. That has to be done in c++ See the exemple below to define TH1F* hts_5_53; TH1F* hts_5_54; …… TH1F* hts_5_69; to book hts_5_53= HDir.make("hts_5_53")," Title", 100,0.,100.); hts_5_54-HDir.make("hts_5_54")," Title", 100,0.,100.); …… hts_16_69-HDir.make("hts_16_69")," Title", 100,0.,100.); to fill hts_5_53-Fill(f) hts_5_54-Fill(f) …… hts_16_69-Fill(f) Instead I would like to define, book and fill in 3 for loops. e.g . for(int i=5, i<17, ++i){ for(int j=53, j<70, ++j){ hts_i_j } } how can I get the string hts to concatenate with the indices ( i,j) in a simple short way while defining, booking and filling in 3 for loop instead
