  • Jquery flowplayer - tabs - content inside div tags not displaying

    - by Gublooo
    Hey guys, I'm looking for a simple example of JQuery tabs in which I am planning to show two different forms. I came across this example http://flowplayer.org/tools/demos/tabs/index.htm which is perfect for my needs. So I implemented the simple example. The code in question is: <div class="panes" <divFirst tab content. Tab contents are called "panes"</div <divSecond tab content</div <divThird tab content</div </div Now my content for the first tab is a form which has several of its own div tags - when I put that form with div tags as the content for the first tab - nothing appears. So I made a simple change and added another div tag to the content of the first tab as shown below and still nothing appears: <div class="panes" <div<divFirst tab content. Tab contents are called "panes"</div</div <divSecond tab content</div <divThird tab content</div </div Is there a simple way to fix this. This is the content that I want to display in my first tab - Thanks for your help <div id="formbox" class="formbox" <form id="shopping_form" method="post" <div id="3" style="width:520px;" <textarea id="message" name="message" rows="3" cols="50"</textarea </div <div id="store_row" style="width:220px;float:left;padding-bottom:10px;"<bStore</b <input type="text" id="store" name="store" class="required" size="20" / <input type="hidden" id="store_id"/ </div <div id="city_column" style="width:200px;float:left;padding-bottom:10px;"<bCity</b <input type="text" id="city" name="city" size="15"/ </div <div id="findbutton_column" style="vertical-align:top;width:80px;float:left;" <input class="find_address" id="findaddress" type="button" value="Find Store"/ </div <div id="googlerow" style="width:120px;float:left;padding-bottom:10px;" <bSelect Store</b<select id="google_stores" name="google_stores"</select <input type="hidden" id="google_address"/ </div <div id="google_message" style="float:left;padding-bottom:10px;display:none;"</div <div id="locationrow" style="float:left;padding-bottom:10px;display:none;" <bAddress/Country</b <input type="text" id="address" name="address" size="20" / <input type="text" id="country" name="country" size="20"/ </div <div style="width:520px;float:left;padding-bottom:10px;" <bPrice    <input type="text" id="price" name="price" size="20" / </div <div id="buttonrow" style="width:200px;float:right;display:none;" <input id="it" type="image" src="http://images.pe.com.s3.amazonaws.com/it.png" height="35px"/ </div </form </div

  • TomTom GO & Ubuntu Linux: impersonating a GPRS phone with dund

    - by Broam
    Background: I've called TomTom support, and they don't support Linux. I can get my GO 730 to mount Mass Storage, and I found a shell script that will allow me to install maps (haven't tried it; will update when I do.). As of note: USB 2.0 only. 1.1 ports will not work. However--I still can't update the TomTom or take advantage of any traffic services. The GO will connect to a mobile phone, but I don't have one that supports tethering. However, I've found a site that claims to know a way to get a Linux Machine to impersonate a phone advertising GPRS services and it apparently works in Fedora as old as FC4. I'm having some serious trouble getting this to work on Ubuntu 9.10 Karmic, mainly because I think some of the built-in bluetooth stuff is getting in the way. Changing the class bits in main.conf (hcid.conf does not exist) doesn't crash..., and dund starts and listens, but the TomTom device never seems to want to connect to my machine. I haven't played around much with sdcptool (I think that's the name, not in front of a Linux machine right now) but maybe I have to advertise the DUN profile...I'm not very sure. My Question: I have no way to diagnose the problems. What are some diagnostic tools I can use to help dig down and figure out what's going on? Update: apparently dund is a legacy tool that's going away. What replaces it?

  • .NET 1.0 ThreadPool Question

    - by dotnet-practitioner
    I am trying to spawn a thread to take care of DoWork task that should take less than 3 seconds. Inside DoWork its taking 15 seconds. I want to abort DoWork and transfer the control back to main thread. I have copied the code as follows and its not working. Instead of aborting DoWork, it still finishes DoWork and then transfers the control back to main thread. What am I doing wrong? class Class1 { /// <summary> /// The main entry point for the application. /// </summary> /// private static System.Threading.ManualResetEvent[] resetEvents; [STAThread] static void Main(string[] args) { resetEvents = new ManualResetEvent[1]; int i = 0; resetEvents[i] = new ManualResetEvent(false); ThreadPool.QueueUserWorkItem(new WaitCallback(DoWork),(object)i); Thread.CurrentThread.Name = "main thread"; Console.WriteLine("[{0}] waiting in the main method", Thread.CurrentThread.Name); DateTime start = DateTime.Now; DateTime end ; TimeSpan span = DateTime.Now.Subtract(start); //abort dowork method if it takes more than 3 seconds //and transfer control to the main thread. do { if (span.Seconds < 3) WaitHandle.WaitAll(resetEvents); else resetEvents[0].Set(); end = DateTime.Now; span = end.Subtract(start); }while (span.Seconds < 2); Console.WriteLine(span.Seconds); Console.WriteLine("[{0}] all done in the main method",Thread.CurrentThread.Name); Console.ReadLine(); } static void DoWork(object o) { int index = (int)o; Thread.CurrentThread.Name = "do work thread"; //simulate heavy duty work.

  • SQLiteOpenHelper.getWriteableDatabase() null pointer exception on Android

    - by Drew Dara-Abrams
    I've had fine luck using SQLite with straight, direct SQL in Android, but this is the first time I'm wrapping a DB in a ContentProvider. I keep getting a null pointer exception when calling getWritableDatabase() or getReadableDatabase(). Is this just a stupid mistake I've made with initializations in my code or is there a bigger issue? public class DatabaseProvider extends ContentProvider { ... private DatabaseHelper databaseHelper; private SQLiteDatabase db; ... @Override public boolean onCreate() { databaseHelper = new DatabaseProvider.DatabaseHelper(getContext()); return (databaseHelper == null) ? false : true; } ... @Override public Uri insert(Uri uri, ContentValues values) { db = databaseHelper.getWritableDatabase(); // NULL POINTER EXCEPTION HERE ... } private static class DatabaseHelper extends SQLiteOpenHelper { public static final String DATABASE_NAME = "cogsurv.db"; public static final int DATABASE_VERSION = 1; public static final String[] TABLES = { "people", "travel_logs", "travel_fixes", "landmarks", "landmark_visits", "direction_distance_estimates" }; // people._id does not AUTOINCREMENT, because it's set based on server's people.id public static final String[] CREATE_TABLE_SQL = { "CREATE TABLE people (_id INTEGER PRIMARY KEY," + "server_id INTEGER," + "name VARCHAR(255)," + "email_address VARCHAR(255))", "CREATE TABLE travel_logs (_id INTEGER PRIMARY KEY AUTOINCREMENT," + "server_id INTEGER," + "person_local_id INTEGER," + "person_server_id INTEGER," + "start DATE," + "stop DATE," + "type VARCHAR(15)," + "uploaded VARCHAR(1))", "CREATE TABLE travel_fixes (_id INTEGER PRIMARY KEY AUTOINCREMENT," + "datetime DATE, " + "latitude DOUBLE, " + "longitude DOUBLE, " + "altitude DOUBLE," + "speed DOUBLE," + "accuracy DOUBLE," + "travel_mode VARCHAR(50), " + "person_local_id INTEGER," + "person_server_id INTEGER," + "travel_log_local_id INTEGER," + "travel_log_server_id INTEGER," + "uploaded VARCHAR(1))", "CREATE TABLE landmarks (_id INTEGER PRIMARY KEY AUTOINCREMENT," + "server_id INTEGER," + "name VARCHAR(150)," + "latitude DOUBLE," + "longitude DOUBLE," + "person_local_id INTEGER," + "person_server_id INTEGER," + "uploaded VARCHAR(1))", "CREATE TABLE landmark_visits (_id INTEGER PRIMARY KEY AUTOINCREMENT," + "server_id INTEGER," + "person_local_id INTEGER," + "person_server_id INTEGER," + "landmark_local_id INTEGER," + "landmark_server_id INTEGER," + "travel_log_local_id INTEGER," + "travel_log_server_id INTEGER," + "datetime DATE," + "number_of_questions_asked INTEGER," + "uploaded VARCHAR(1))", "CREATE TABLE direction_distance_estimates (_id INTEGER PRIMARY KEY AUTOINCREMENT," + "server_id INTEGER," + "person_local_id INTEGER," + "person_server_id INTEGER," + "travel_log_local_id INTEGER," + "travel_log_server_id INTEGER," + "landmark_visit_local_id INTEGER," + "landmark_visit_server_id INTEGER," + "start_landmark_local_id INTEGER," + "start_landmark_server_id INTEGER," + "target_landmark_local_id INTEGER," + "target_landmark_server_id INTEGER," + "datetime DATE," + "direction_estimate DOUBLE," + "distance_estimate DOUBLE," + "uploaded VARCHAR(1))" }; public DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); Log.v(Constants.TAG, "DatabaseHelper()"); } @Override public void onCreate(SQLiteDatabase db) { Log.v(Constants.TAG, "DatabaseHelper.onCreate() starting"); // create the tables int length = CREATE_TABLE_SQL.length; for (int i = 0; i < length; i++) { db.execSQL(CREATE_TABLE_SQL[i]); } Log.v(Constants.TAG, "DatabaseHelper.onCreate() finished"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { for (String tableName : TABLES) { db.execSQL("DROP TABLE IF EXISTS" + tableName); } onCreate(db); } } } As always, thanks for the assistance! -- Not sure if this detail helps, but here's LogCat showing the exception:

  • Recursive move utility on Unix?

    - by Thomas Vander Stichele
    Sometimes I have two trees that used to have the same content, but have grown out of sync (because I moved disks around or whatever). A good example is a tree where I mirror upstream packages from Fedora. I want to merge those two trees again by moving all of the files from tree1 into tree2. Usually I do this with: rsync -arv tree1/* tree2 Then delete tree1. However, this takes an awful lot of time and disk space, and it would be much easier to be able to do: mv -r tree1/* tree2 In other words, a recursive move. It would be faster because first of all it would not even copy, just move the inodes, and second I wouldn't need a delete at the end. Does this exist ? As a test case, consider the following sequence of commands: $ mkdir -p a/b $ touch a/b/c1 $ rsync -arv a/ a2 sending incremental file list created directory ./ b/ b/c1 b/c2 sent 173 bytes received 57 bytes 460.00 bytes/sec total size is 0 speedup is 0.00 $ touch a/b/c2 What command would now have the effect of moving a/b/c2 to a2/b/c2 and then deleting the a subtree (since everything in it is already in the destination tree) ?

  • NTRU Pseudo-code for computing Polynomial Inverses

    - by Neville
    Hello all. I was wondering if anyone could tell me how to implement line 45 of the following pseudo-code. Require: the polynomial to invert a(x), N, and q. 1: k = 0 2: b = 1 3: c = 0 4: f = a 5: g = 0 {Steps 5-7 set g(x) = x^N - 1.} 6: g[0] = -1 7: g[N] = 1 8: loop 9: while f[0] = 0 do 10: for i = 1 to N do 11: f[i - 1] = f[i] {f(x) = f(x)/x} 12: c[N + 1 - i] = c[N - i] {c(x) = c(x) * x} 13: end for 14: f[N] = 0 15: c[0] = 0 16: k = k + 1 17: end while 18: if deg(f) = 0 then 19: goto Step 32 20: end if 21: if deg(f) < deg(g) then 22: temp = f {Exchange f and g} 23: f = g 24: g = temp 25: temp = b {Exchange b and c} 26: b = c 27: c = temp 28: end if 29: f = f XOR g 30: b = b XOR c 31: end loop 32: j = 0 33: k = k mod N 34: for i = N - 1 downto 0 do 35: j = i - k 36: if j < 0 then 37: j = j + N 38: end if 39: Fq[j] = b[i] 40: end for 41: v = 2 42: while v < q do 43: v = v * 2 44: StarMultiply(a; Fq; temp;N; v) 45: temp = 2 - temp mod v 46: StarMultiply(Fq; temp; Fq;N; v) 47: end while 48: for i = N - 1 downto 0 do 49: if Fq[i] < 0 then 50: Fq[i] = Fq[i] + q 51: end if 52: end for 53: {Inverse Poly Fq returns the inverse polynomial, Fq, through the argument list.} The function StarMultiply returns a polynomial (array) stored in the variable temp. Basically temp is a polynomial (I'm representing it as an array) and v is an integer (say 4 or 8), so what exactly does temp = 2-temp mod v equate to in normal language? How should i implement that line in my code. Can someone give me an example. The above algorithm is for computing Inverse polynomials for NTRUEncrypt key generation. The pseudo-code can be found on page 28 of this document. Thanks in advance.

  • Is it possible to be a Linux professional studying on your own?

    - by Marc Jr
    I read economics at university(nothing to see with linux, isn't it? :P). I have some basic knowledge about booting process, Linux Kernel compiling from source and stuff like that. But of course I have still much to learn sometimes some errors appears and "voila" I am lost. I had: Ubuntu, Fedora, OpenSuse, Arch.. using Gentoo now. I'd like to know what you linux users, professionals, administrators... would think it is the best way to learn linux in a professional way. Is it worth studying it and passing the LPIC test enough to work in the linux world? or do I need going to IT uni? I've heard LFS is a good way of learning about linux, is that real? I've been thinking about getting to LFS learn about more deeply about the linux process and learning scripts. It is possible to do this way? if anyone has a tip or a good way of doing, maybe someone did it. Any tip is very welcome. Words from a person in love with linux. :D The best, Marc

  • Where should CentOS users get /usr/share/virtio-win/drivers for virt-v2v?

    - by Philip Durbin
    I need to migrate a number of virtual machines from VMware ESX to CentOS 6 KVM hypervisors. Ultimately, I wrote an RPM spec file that solved my problem at https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec but I'm not sure if there's another RPM in base CentOS or EPEL (something standard) I should be using instead. Originally, I was getting this "No root device found in this operating system image" error when attemting to migrate a Window 2008 VM. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm virt-v2v: No root device found in this operating system image. . . . but I solved this with a simply yum install libguestfs-winsupport since the docs say: If you attempt to convert a virtual machine using NTFS without the libguestfs-winsupport package installed, the conversion will fail. Next I got an error about missing drivers for Windows 2008. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/amd64/Win2008 . . . and I resolved this by grabbing an iso from Fedora at http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ as recommended by http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers and building an RPM from it with this spec file: https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec Now, virt-v2v exits without error: [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: my-vm configured with virtio drivers. [root@kvm01b ~]# Now, my question is, rather that the virtio-win RPM from the spec file I wrote, is there some other more standard RPM in base CentOS or EPEL that will resolve the error above?

  • bind9 "error sending response: host unreachable"

    - by wolfgangsz
    of course), I have a number of DNS servers, all running bind9 (9.5.1, to be specific) under fedora. 4 of them are slaves, fed by a common master for our public DNS. These are all located on the public gateways of our various offices. One of them has tons of messages in its log files similar to these: Jul 21 17:26:18 gateway named[3487]: client 10.171.3.8#52500: view internal: error sending response: host unreachable I wonder where that comes from. The firewall is open on port 53 between the two machines (10.171.3.8 is an internal DNS server located on a Windows Domain Controller). The internal domains do NOT list the gateway as a name server (so there should not be any attempts of replicating the domains), and the gateway does not handle any internal DNS. The clients in these messages vary between the two domain controllers on the internal network and a third internal name server (running bind9 on debian in a different segment of the network). Any pointers are highly welcome. In response to the first reply: The issue with this really is that tcpdump doesn't show any problems. Here is an extract from "tcpdump -i any port 53" 09:13:38.283308 IP valine.aminocom.com.61815 ns-pri.ripe.net.domain: 14075 PTR? 166.225.58.95.in-addr.arpa. (44) 09:13:42.007410 IP gateway-eng.aminocom.com.37047 alanine.aminocom.com.domain: 35410+ PTR? 12.3.172.10.in-addr.arpa. (42) At the same time, the DNS log shows: Jul 22 09:13:38 gateway named[3487]: client 10.171.3.6#61300: view internal: error sending response: host unreachable Jul 22 09:13:40 gateway named[3487]: client 10.172.3.12#56230: view internal: error sending response: host unreachable Jul 22 09:13:40 gateway named[3487]: client 10.171.3.8#55221: view internal: error sending response: host unreachable Jul 22 09:13:49 gateway named[3487]: client 10.171.3.8#51342: view internal: error sending response: host unreachable So clearly at 09:13:40 there were two unsuccessful attempts to connect to internal machines (10.172.3.12 and 10.171.3.8, both are DNS servers), but nothing in the tcpdump output.

  • Server Performance

    - by sb12
    I know very little about performance tuning of servers etc... so i thought i'd put this up here as i start some research on it, just to get some direction. I am in the process of migrating from my old server to a new one - both are 64 bit machines. One is a few years old, the other brand new (PowerEdge R410). The old server spec is: 2 cpus, 3.4GHz Pentiums, 8G of RAM, Fedora 11 currently installed The new server spec is: 16 cpus, 3.2 GHz Xeon, 16G of RAM, CentOS 6.2 installed. Also RAID10 is on the new server - no RAID on the old one. Both servers currently have the same database (MySQL) with the same data migrated. I wrote a Perl script that simply steps through each row of a table in the database (about 18000 rows) and updates a value in that row. Every row in the table is updated. Out of curiosity i ran this perl script on both machines, just to see how the new server would perform vs. the old one, and it produced interesting results: The old server was twice as fast as the new one to complete. Looking at the database, both are configured exactly the same (the new one being a dump of the old one...)... Anyone any ideas why this would be given the hardware gap between both? As i said i'm about to start some digging, but thought i'd put this up here to maybe get some good direction.... Many thanks in advance..

  • Creating a Blog ruby on Rails - Problem Deleting Comments

    - by bgadoci
    As I always type I am new to rails and programming in general so go easy. Thanks in advance. I have successfully followed the initial tutorial from Ryan Bates on how to build a weblog in 15 minutes. If you don't know this tutorial takes you through creating posts and allowing for comments on those post. It even introduces AJAX through the creating and displaying comments on the posts show.html.erb page. All works great. Here's the hiccup, when Ryan takes you though this tutorial he clears out the comments_controller and only shows the code for creating comments. I am trying to add back the ability to edit and destroy comments. Can't see to get it to work, keeps deleting the actual post not the comment (log shows that I keep sending DELETE request to PostsController). Here is my code: class CommentsController < ApplicationController def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| format.html { redirect_to @post } format.js end end def destroy @comment = Comment.find(params[:id]) @comment.destroy respond_to do |format| format.html { redirect_to(posts_url) } format.xml { head :ok } end end end /views/posts/show.html.erb <%= render :partial => @post %> <p> <%= link_to 'Edit', edit_post_path (@post) %> | <%= link_to 'Destroy', @post, :method => :delete, :confirm => "Are you sure?" %> | <%= link_to 'See All Posts', posts_path %> </p> <h2>Comments</h2> <div id="comments"> <%= render :partial => @post.comments %> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area :body %> </p> <p> <%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <p> <strong>Posted <%= time_ago_in_words(comment.created_at) %> ago </strong><br/> <%= h(comment.body) %><br/> <%= link_to 'Destroy', @comments, :method => :delete, :confirm => "Are you sure?" %> </p> <% end %>

  • Color Theory: How to convert Munsell HVC to RGB/HSB/HSL

    - by Ian Boyd
    I'm looking at at document that describes the standard colors used in dentistry to describe the color of a tooth. They quote hue, value, chroma values, and indicate they are from the 1905 Munsell description of color: The system of colour notation developed by A. H. Munsell in 1905 identifies colour in terms of three attributes: HUE, VALUE (Brightness) and CHROMA (saturation) [15] HUE (H): Munsell defined hue as the quality by which we distinguish one colour from another. He selected five principle colours: red, yellow, green, blue, and purple; and five intermediate colours: yellow-red, green-yellow, blue-green, purple-blue, and red-purple. These were placed around a colour circle at equal points and the colours in between these points are a mixture of the two, in favour of the nearer point/colour (see Fig 1.). VALUE (V): This notation indicates the lightness or darkness of a colour in relation to a neutral grey scale, which extends from absolute black (value symbol 0) to absolute white (value symbol 10). This is essentially how ‘bright’ the colour is. CHROMA (C): This indicates the degree of divergence of a given hue from a neutral grey of the same value. The scale of chroma extends from 0 for a neutral grey to 10, 12, 14 or farther, depending upon the strength (saturation) of the sample to be evaluated. There are various systems for categorising colour, the Vita system is most commonly used in Dentistry. This uses the letters A, B, C and D to notate the hue (colour) of the tooth. The chroma and value are both indicated by a value from 1 to 4. A1 being lighter than A4, but A4 being more saturated than A1. If placed in order of value, i.e. brightness, the order from brightest to darkest would be: A1, B1, B2, A2, A3, D2, C1, B3, D3, D4, A3.5, B4, C2, A4, C3, C4 The exact values of Hue, Value and Chroma for each of the shades is shown below (16) So my question is, can anyone convert Munsell HVC into RGB, HSB or HSL? Hue Value (Brightness) Chroma(Saturation) === ================== ================== 4.5 7.80 1.7 2.4 7.45 2.6 1.3 7.40 2.9 1.6 7.05 3.2 1.6 6.70 3.1 5.1 7.75 1.6 4.3 7.50 2.2 2.3 7.25 3.2 2.4 7.00 3.2 4.3 7.30 1.6 2.8 6.90 2.3 2.6 6.70 2.3 1.6 6.30 2.9 3.0 7.35 1.8 1.8 7.10 2.3 3.7 7.05 2.4 They say that Value(Brightness) varies from 0..10, which is fine. So i take 7.05 to mean 70.5%. But what is Hue measured in? i'm used to hue being measured in degrees (0..360). But the values i see would all be red - when they should be more yellow, or brown. Finally, it says that Choma/Saturation can range from 0..10 ...or even higher - which makes it sound like an arbitrary scale. So can anyone convert Munsell HVC to HSB or HSL, or better yet, RGB?

  • Blackberry - Listfield layout question

    - by Kai
    I'm having an interesting anomaly when displaying a listfield on the blackberry simulator: The top item is the height of a single line of text (about 12 pixels) while the rest are fine. Does anyone know why only the top item is being drawn this way? Also, when I add an empty venue in position 0, it still displays the first actual venue this way (item in position 1). Not sure what to do. Thanks for any help. The layout looks like this: ----------------------------------- | *part of image* | title | ----------------------------------- | | title | | * full image * | address | | | city, zip | ----------------------------------- The object is called like so: listField = new ListField( venueList.size() ); listField.setCallback( this ); listField.setSelectedIndex(-1); _middle.add( listField ); Here is the drawListRow code: public void drawListRow( ListField listField, Graphics graphics, int index, int y, int width ) { listField.setRowHeight(90); Hashtable item = (Hashtable) venueList.elementAt( index ); String venue_name = (String) item.get("name"); String image_url = (String) item.get("image_url"); String address = (String) item.get("address"); String city = (String) item.get("city"); String zip = (String) item.get("zip"); EncodedImage img = null; try { String filename = image_url.substring(image_url.indexOf("crop/") + 5, image_url.length() ); FileConnection fconn = (FileConnection)Connector.open( "file:///SDCard/Blackberry/project1/" + filename, Connector.READ); if ( !fconn.exists() ) { } else { InputStream input = fconn.openInputStream(); byte[] data = new byte[(int)fconn.fileSize()]; input.read(data); input.close(); if(data.length > 0) { EncodedImage rawimg = EncodedImage.createEncodedImage( data, 0, data.length); int dw = Fixed32.toFP(Display.getWidth()); int iw = Fixed32.toFP(rawimg.getWidth()); int sf = Fixed32.div(iw, dw); img = rawimg.scaleImage32(sf * 4, sf * 4); } else { } } } catch(IOException ef) { } graphics.drawText( venue_name, 140, y, 0, width ); graphics.drawText( address, 140, y + 15, 0, width ); graphics.drawText( city + ", " + zip, 140, y + 30, 0, width ); if(img != null) { graphics.drawImage(0, y, img.getWidth(), img.getHeight(), img, 0, 0, 0); } }

  • Lawler's Algorithm Implementation Assistance

    - by Richard Knop
    Here is my implemenation of Lawler's algorithm in PHP (I know... but I'm used to it): <?php $jobs = array(1, 2, 3, 4, 5, 6); $jobsSubset = array(2, 5, 6); $n = count($jobs); $processingTimes = array(2, 3, 4, 3, 2, 1); $dueDates = array(3, 15, 9, 7, 11, 20); $optimalSchedule = array(); foreach ($jobs as $j) { $optimalSchedule[] = 0; } $dicreasedCardinality = array(); for ($i = $n; $i >= 1; $i--) { $x = 0; $max = 0; // loop through all jobs for ($j = 0; $j < $i; $j++) { // ignore if $j already is in the $dicreasedCardinality array if (false === in_array($j, $dicreasedCardinality)) { // if the job has no succesor in $jobsSubset if (false === isset($jobs[$j+1]) || false === in_array($jobs[$j+1], $jobsSubset)) { // here I find an array index of a job with the maximum due date // amongst jobs with no sucessor in $jobsSubset if ($x < $dueDates[$j]) { $x = $dueDates[$j]; $max = $j; } } } } // move the job at the end of $optimalSchedule $optimalSchedule[$i-1] = $jobs[$max]; // decrease the cardinality of $jobs $dicreasedCardinality[] = $max; } print_r($optimalSchedule); Now the above returns an optimal schedule like this: Array ( [0] => 1 [1] => 1 [2] => 1 [3] => 3 [4] => 2 [5] => 6 ) Which doesn't seem right to me. The problem might be with my implementation of the algorithm because I am not sure I understand it correctly. I used this source to implement it: http://www.google.com/books?id=aSiBs6PDm9AC&pg=PA166&dq=lawler%27s+algorithm+code&lr=&hl=sk&cd=4#v=onepage&q=&f=false The description there is a little confusing. For example, I didn't quite get how is the subset D defined (I guess it is arbitrary). Could anyone help me out with this? I have been trying to find some sources with simpler explanation of the algorithm but all sources I found were even more complicated (with math proofs and such) so I am stuck with the link above. Yes, this is a homework, if it wasn't obvious. I still have few weeks to crack this but I have spent few days already trying to get how exactly this algorithm works with no success so I don't think I will get any brighter during that time.

  • WPF: How to specify units in Dialog Units?

    - by Ian Boyd
    i'm trying to figure out how to layout a simple dialog in WPF using the proper dialog units (DLUs). i spent about two hours dimensioning this sample dialog box from Windows Vista with the various dlu measurements. Can someone please give the corresponding XAML markup that generates this dialog box? (Image Link) Now admittedly i know almost nothing about WPF XAML. Every time i start, i get stymied because i cannot figure out how to place any control. It seems that everything in WPF must be contained on a panel of some kind. There's StackPanels, FlowPanels, DockPanel, Grid, etc. If you don't have one of these then it won't compile. The only XAML i've been able to come up with (uing XAMLPad) so far: <DockPanel xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Image Width="23" /> <Label>Are you sure you want to move this file to the Recycle Bin?</Label> <Image Width="60" /> <Label>117__6.jpg</Label> <Label>Type: ACDSee JPG Image</Label> <Label>Rating: Unrated</Label> <Label>Dimensions: 1072 × 712</Label> <Button Content="Yes" Width="50" Height="14"/> <Button Content="Cancel" Width="50" Height="14"/> </DockPanel> Which renders as a gaudy monstrosity. None of the controls are placed or sized right. i cannot figure out how to position controls in a window, nor size them properly. Can someone turn that screenshot into XAML? Note: You're not allowed to measure the screenshot. All the Dialog Unit (dlu) widths and heights are specified. Note: 1 horizontal DLU != 1 vertical DLU. Horizontal and vertical DLUs are different sizes.

My HfJsonValue contains the following json data {"Table" : [{"Emp_Id" : "3","Identity_No" : "","Emp_Name" : "Jerome","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Supervisior","Desig_Description" : "Supervisior of the Construction","SalaryBasis" : "Monthly","FixedSalary" : "25000.00"},{"Emp_Id" : "4","Identity_No" : "","Emp_Name" : "Mohan","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Acc ","Desig_Description" : "Accountant","SalaryBasis" : "Monthly","FixedSalary" : "200.00"},{"Emp_Id" : "5","Identity_No" : "","Emp_Name" : "Murugan","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Mason","Desig_Description" : "Mason","SalaryBasis" : "Weekly","FixedSalary" : "150.00"},{"Emp_Id" : "6","Identity_No" : "","Emp_Name" : "Ram","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Mason","Desig_Description" : "Mason","SalaryBasis" : "Weekly","FixedSalary" : "120.00"},{"Emp_Id" : "7","Identity_No" : "","Emp_Name" : "Raja","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Mason","Desig_Description" : "Mason","SalaryBasis" : "Weekly","FixedSalary" : "135.00"},{"Emp_Id" : "8","Identity_No" : "","Emp_Name" : "Raja kumar","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Mason Helper","Desig_Description" : "Mason Helper","SalaryBasis" : "Weekly","FixedSalary" : "105.00"},{"Emp_Id" : "9","Identity_No" : "","Emp_Name" : "Lakshmi","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Mason Helper","Desig_Description" : "Mason Helper","SalaryBasis" : "Weekly","FixedSalary" : "100.00"},{"Emp_Id" : "10","Identity_No" : "","Emp_Name" : "Palani","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Carpenter","Desig_Description" : "Carpenter","SalaryBasis" : "Weekly","FixedSalary" : "200.00"},{"Emp_Id" : "11","Identity_No" : "","Emp_Name" : "Annamalai","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Carpenter","Desig_Description" : "Carpenter","SalaryBasis" : "Weekly","FixedSalary" : "220.00"},{"Emp_Id" : "12","Identity_No" : "","Emp_Name" : "David","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Steel Fixer","Desig_Description" : "Steel Fixer","SalaryBasis" : "Weekly","FixedSalary" : "220.00"},{"Emp_Id" : "13","Identity_No" : "","Emp_Name" : "Chandru","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Steel Fixer","Desig_Description" : "Steel Fixer","SalaryBasis" : "Weekly","FixedSalary" : "220.00"},{"Emp_Id" : "14","Identity_No" : "","Emp_Name" : "Mani","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Steel Helper","Desig_Description" : "Steel Helper","SalaryBasis" : "Weekly","FixedSalary" : "175.00"},{"Emp_Id" : "15","Identity_No" : "","Emp_Name" : "Karthik","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Wood Fixer","Desig_Description" : "Wood Fixer","SalaryBasis" : "Weekly","FixedSalary" : "195.00"},{"Emp_Id" : "16","Identity_No" : "","Emp_Name" : "Bala","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Wood Fixer","Desig_Description" : "Wood Fixer","SalaryBasis" : "Weekly","FixedSalary" : "185.00"},{"Emp_Id" : "17","Identity_No" : "","Emp_Name" : "Tamil arasi","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Wood Helper","Desig_Description" : "Wood Helper","SalaryBasis" : "Weekly","FixedSalary" : "185.00"},{"Emp_Id" : "18","Identity_No" : "","Emp_Name" : "Perumal","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Cook","Desig_Description" : "Cook","SalaryBasis" : "Weekly","FixedSalary" : "105.00"},{"Emp_Id" : "19","Identity_No" : "","Emp_Name" : "Andiappan","Address" : "Madurai","Date_Of_Birth" : "","Desig_Name" : "Watchman","Desig_Description" : "Watchman","SalaryBasis" : "Weekly","FixedSalary" : "150.00"}]}

  • Asynchronous readback from opengl front buffer using multiple PBO's

    - by KillianDS
    I am developing an application that needs to read back the whole frame from the front buffer of an openGL application. I can hijack the application's opengl library and insert my code on swapbuffers. At the moment I am successfully using a simple but excruciating slow glReadPixels command without PBO's. Now I read about using multiple PBO's to speed things up. While I think I've found enough resources to actually program that (isn't that hard), I have some operational questions left. I would do something like this: create a series (e.g. 3) of PBO's use glReadPixels in my swapBuffers override to read data from front buffer to a PBO (should be fast and non-blocking, right?) Create a seperate thread to call glMapBufferARB, once per PBO after a glReadPixels, because this will block until the pixels are in client memory. Process the data from step 3. Now my main concern is of course in steps 2 and 3. I read about glReadPixels used on PBO's being non-blocking, will this be an issue if I issue new opengl commands after that very fast? Will those opengl commands block? Or will they continue (my guess), and if so, I guess only swapbuffers can be a problem, will this one stall or will glReadPixels from front buffer be many times faster than swapping (about each 15-30ms) or, worst case scenario, will swapbuffers be executed while glReadPixels is still reading data to the PBO? My current guess is this logic will do something like this: copy FRONT_BUFFER - generic place in VRAM, copy VRAM-RAM. But I have no idea which of those 2 is the real bottleneck and more, what the influence on the normal opengl command stream is. Then in step 3. Is it wise to do this asynchronously in a thread separated from normal opengl logic? At the moment I think not, It seems you have to restore buffer operations to normal after doing this and I can't install synchronization objects in the original code to temporarily block those. So I think my best option is to define a certain swapbuffer delay before reading them out, so e.g. calling glReadPixels on PBO i%3 and glMapBufferARB on PBO (i+2)%3 in the same thread, resulting in a delay of 2 frames. Also, when I call glMapBufferARB to use data in client memory, will this be the bottleneck or will glReadPixels (asynchronously) be the bottleneck? And finally, if you have some better ideas to speed up frame readback from GPU in opengl, please tell me, because this is a painful bottleneck in my current system. I hope my question is clear enough, I know the answer will probably also be somewhere on the internet but I mostly came up with results that used PBO's to keep buffers in video memory and do processing there. I really need to read back the front buffer to RAM and I do not find any clear explanations about performance in that case (which I need, I cannot rely on "it's faster", I need to explain why it's faster). Thank you

  • How does enterprise failover, such as with google.com, actually work?

    - by Alex Regan
    We have a few fedora systems that are configured for web, FTP, and email services. We'd like to mirror these services, so that we can provide near 100% reliability for our users. I'm a fairly experienced Linux administrator, but don't have much experience with redundant systems. What is the best way to do this? How does google and amazon do it? Google.com resolves to multiple IP addresses, but if my local desktop caches one of the IPs that are unreachable, I'm going to get a failed connection message. How do they prevent that from happening? If one of their servers goes down, how is it automatically redirected to another system, without the end-user ever knowing it? I understand there are failover devices, but they're only for failing over the system itself, not a complete network. Let's say we have the worst-case scenario, such as my primary system becomes inaccessible. What are the fundamental components that are used on Linux systems to provide this capability? I'm looking for concepts, or approaches, not answers like "check out openstack". What are the actual pieces that make up the solution? What has to be done to implement this capability? Hopefully my question is clear. I'd like to know what the pieces are that make up a failover system and what approach is taken by successful organizations that implement it. Thanks again, Alex

  • Processing an Integer Buried in a String in XSL

    - by justkt
    I have a stored time value which is of the format H:mm:ss. The hours may be any value from 0 up through several days. This data is sent in an XML tag and processed by XSL to be displayed. The display that I want is of the format: D days, HH:mm:ss (hours/minutes) Where the last tag shows hours if HH is greater than 0, minutes if it is 0. Given the original HH, which may be more than 24, I know I need the floor of HH / 24 to get the days value. Then the original HH % 24 gives me the leftover hours. I have also handled the minutes and hours question using xsl:when and xsl:if. It's getting days and hours from the hours value that has me stumped. EDIT So far, I'm looking at doing the following: Variable declaration <xsl:variable name="time"><xsl:value-of select="time" /><xsl:variable> <xsl:variable name="days"><xsl:value-of select="floor(substring-before(time, ':') / 24)" /></xsl:variable> <xsl:variable name="hours"><xsl:value-of select="substring-before(time, ':') mod 24" /></xsl:variable> <xsl:variable name="minutes"><xsl:value-of select="substring-after(time, ':')" /></xsl:variable> Use <xsl:if test="$days > 0"> <xsl:value-of select="$days" /> days </xsl:if> <xsl:value-of select="$hours" />:<xsl:value-of select="$minutes" /> <xsl:choose> <xsl:when test="$hours > 0"> hour<xsl:if test="$hours > 1">s</xsl:if> </xsl:when> <xsl:otherwise> minute<xsl:if test="$minute != '01:00'">s</xsl:if> </xsl:otherwise> </xsl:choose> And for clarification, a sample time would be <time>26:15:00</time> for 1 day 2:15 hours.

  • Code Complete 2ed, composition and delegation.

    - by Arlukin
    Hi there. After a couple of weeks reading on this forum I thought it was time for me to do my first post. I'm currently rereading Code Complete. I think it's 15 years since the last time, and I find that I still can't write code ;-) Anyway on page 138 in Code Complete you find this coding horror example. (I have removed some of the code) class Emplyee { public: FullName GetName() const; Address GetAddress() const; PhoneNumber GetWorkPhone() const; ... bool IsZipCodeValid( Address address); ... private: ... } What Steve thinks is bad is that the functions are loosely related. Or has he writes "There's no logical connection between employees and routines that check ZIP codes, phone numbers or job classifications" Ok I totally agree with him. Maybe something like the below example is better. class ZipCode { public: bool IsValid() const; ... } class Address { public: ZipCode GetZipCode() const; ... } class Employee { public: Address GetAddress() const; ... } When checking if the zip is valid you would need to do something like this. employee.GetAddress().GetZipCode().IsValid(); And that is not good regarding to the Law of Demeter ([http://en.wikipedia.org/wiki/Law_of_Demeter][1]). So if you like to remove two of the three dots, you need to use delegation and a couple of wrapper functions like this. class ZipCode { public: bool IsValid(); } class Address { public: ZipCode GetZipCode() const; bool IsZipCodeValid() {return GetZipCode()->IsValid()); } class Employee { public: FullName GetName() const; Address GetAddress() const; bool IsZipCodeValid() {return GetAddress()->IsZipCodeValid()); PhoneNumber GetWorkPhone() const; } employee.IsZipCodeValid(); But then again you have routines that has no logical connection. I personally think that all three examples in this post are bad. Is it some other way that I haven't thougt about? //Daniel
