  • Windows Server 2008 R2 + IIS 7.5 + ASP.NET 4.0 = HTTP Error 500.0

    - by Dave
    I am having an impossible time getting asp.net 4.0 to work in any fashion at all. In fact, I completely wiped my server, reinstalled with Server 2008 R2 Standard (running on a VMWare ESXi box, not that it should matter), and cannot even get a test .aspx page to work. Here is exactly what I did: Installed 2008 R2 Standard Activated windows and enabled Remote Desktop Installed the Web Server Role with the necessary role services(common http, asp.net, logging, tracing, management service and FTP) Enabled the management service Installed .Net Framework 4.0 via web executable Added FTP publishing to the default web site Switched default web site application pool to asp.net 4.0 (integrated) Added a 'test.aspx' file to the inetpub\wwwroot folder (contents below) Opened a browser to http://localhost/test.aspx and received a 500.0 error (also below) What am I missing? I haven't touched IIS in a while (3+ years), so it could be something stupid/trvial. Please point it out, call me a noob; my ego can take it.

  • How to use Devicemotion/Gyroscope to move a dot from center to 8 directions of iphone screen

    - by iSeeker
    I am trying to move a dot at center to 8 directions of iphone screen using Devicemotion such that it moves faster when tilted at a faster rate. Rough sketch is below: I could find a similar implementation in an app called Gyrododge in appstore, i cant figure out how to make it work... Update: This is what i have done so far, but the response is not smooth, and is very jittery.. xdiff and ydiff are the change of device attitude in x and y directions, derived from quatenion implementation. if (currDeviceMotion.rotationRate.x < -2) { NSLog(@"To Top"); if (195+800*ydiff >=193 && 195+800*ydiff <= 197) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (195+800*ydiff >=390 ) { [self.pitchDot setFrame:CGRectMake(150, 390, 20, 20)]; }else if (195+800*ydiff <= 0){ [self.pitchDot setFrame:CGRectMake(150, 0, 20, 20)]; }else if(195+800*ydiff < 194){ [self.pitchDot setFrame:CGRectMake(150, 195+800*ydiff, 20, 20)]; }else if(195+800*ydiff > 196){ [self.pitchDot setFrame:CGRectMake(150, 195+800*ydiff, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.x > 2){ NSLog(@"To Bottom"); if (195+800*ydiff >=193 && 195+800*ydiff <= 197) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (195+800*ydiff >=390 ) { [self.pitchDot setFrame:CGRectMake(150, 390, 20, 20)]; }else if (195+800*ydiff <= 0){ [self.pitchDot setFrame:CGRectMake(150, 0, 20, 20)]; }else if(195+800*ydiff < 194){ [self.pitchDot setFrame:CGRectMake(150, 195+800*ydiff, 20, 20)]; }else if(195+800*ydiff > 196){ [self.pitchDot setFrame:CGRectMake(150, 195+800*ydiff, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.y < -2){ NSLog(@"To Left"); if (150+500*xdiff >= 148 && 150+500*xdiff <=152) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (150+500*xdiff >= 300 ) { [self.pitchDot setFrame:CGRectMake(300, 195, 20, 20)]; }else if (150+500*xdiff <= 0){ [self.pitchDot setFrame:CGRectMake(0, 195, 20, 20)]; }else if(150+500*xdiff < 148){ [self.pitchDot setFrame:CGRectMake(150+500*xdiff, 195, 20, 20)]; }else if(150+500*xdiff > 152){ [self.pitchDot setFrame:CGRectMake(150+500*xdiff, 195, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.y > 2){ NSLog(@"To Right"); if (150+500*xdiff >= 148 && 150+500*xdiff <=152) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (150+500*xdiff >= 300 ) { [self.pitchDot setFrame:CGRectMake(300, 195, 20, 20)]; }else if (150+500*xdiff <= 0){ [self.pitchDot setFrame:CGRectMake(0, 195, 20, 20)]; }else if(150+500*xdiff < 148){ [self.pitchDot setFrame:CGRectMake(150+500*xdiff, 195, 20, 20)]; }else if(150+500*xdiff > 152){ [self.pitchDot setFrame:CGRectMake(150+500*xdiff, 195, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.x < -0.20 && currDeviceMotion.rotationRate.y > 0.20 ){ NSLog(@"To Diagonal Right Top"); if (150+650*xdiff >= 148 && 150+650*xdiff <=152) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (150+650*xdiff >= 300 ) { [self.pitchDot setFrame:CGRectMake(300, 0, 20, 20)]; }else if(150+650*xdiff > 152){ [self.pitchDot setFrame:CGRectMake(150+650*xdiff, 195-1.3*650*xdiff, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.x > 0.20 && currDeviceMotion.rotationRate.y < -0.20 ){ NSLog(@"To Diagonal Left Bottom"); if (150+650*xdiff >= 148 && 150+650*xdiff <=152) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (150+650*xdiff <= 0 ) { [self.pitchDot setFrame:CGRectMake(0, 390, 20, 20)]; }else if(150+650*xdiff < 148){ [self.pitchDot setFrame:CGRectMake(150+650*xdiff, 195-1.3*650*xdiff, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.x < -0.20 && currDeviceMotion.rotationRate.y < -0.20 ){ NSLog(@"To Diagonal Left Top and xdiff is %f",xdiff); if (150+650*xdiff >= 148 && 150+650*xdiff <=152) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (150+650*xdiff <= 0 ) { [self.pitchDot setFrame:CGRectMake(0, 0, 20, 20)]; }else if(150+650*xdiff < 148){ [self.pitchDot setFrame:CGRectMake(150+650*xdiff, 195+1.3*650*xdiff, 20, 20)]; } } }else if (currDeviceMotion.rotationRate.x > 0.20 && currDeviceMotion.rotationRate.y > 0.20 ){ NSLog(@"To Diagonal Right Bottom"); if (150+650*xdiff >= 148 && 150+650*xdiff <=152) { [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; }else{ if (150+650*xdiff >= 300 ) { [self.pitchDot setFrame:CGRectMake(300, 390, 20, 20)]; }else if(150+650*xdiff > 152){ [self.pitchDot setFrame:CGRectMake(150+650*xdiff, 195+1.3*650*xdiff, 20, 20)]; } } }else if((currDeviceMotion.rotationRate.x < 0.20 && currDeviceMotion.rotationRate.x < -0.20) ||(currDeviceMotion.rotationRate.y < 0.20 && currDeviceMotion.rotationRate.y < -0.20) ||(currDeviceMotion.rotationRate.z < 0.20 && currDeviceMotion.rotationRate.z < -0.20)){ [self.rollDot setFrame:CGRectMake(150, 195, 20, 20)]; [self.pitchDot setFrame:CGRectMake(150, 195, 20, 20)]; } It could be great if i could make it move like the application i have stated above, called Gyrododge This link also addresses a similar question:Link. Any advice or help is greatly appreciated... Thanks.

  • Why does my Perl CGI script cause a 500 internal server error?

    - by Nitish
    I get a 500 internal server error when I try to run the code below in a web server which supports perl: #! /usr/bin/perl use LWP; my $ua = LWP::UserAgent->new; $ua->agent("TestApp/0.1 "); $ua->env_proxy(); my $req = HTTP::Request->new(POST => 'http://www.google.com/loc/json'); $req->content_type('application/jsonrequest'); $req->content('{ "cell_towers": [{"location_area_code": "55000", "mobile_network_code": "95", "cell_id": "20491", "mobile_country_code": "404"}], "version": "1.1.0", "request_address": "true"}'); my $res = $ua->request($req); if ($res->is_success) { print $res->content,"\n"; } else { print $res->status_line, "\n"; return undef; } But there is no error when I run the code below: #! /usr/bin/perl use CGI::Carp qw(fatalsToBrowser); print "Content-type: text/html\n\n"; print "<HTML>\n"; print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H2>Hello World!</H2> <br /> \n"; foreach $key (sort keys(%ENV)) { print "$key = $ENV{$key}<p>" ; } print "</BODY>\n"; print "</HTML>\n"; So I think there is some problem with my code. When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please.

  • What could trigger a change of http status to 500 on the client's end?

    - by VexedPanda
    We have a PHP web application that posts data to itself, and either displays an updated page based on that data, or redirects to another page. An example of this is a script with a paged list on it, where clicking on the Next link causes a post to the same page, which then returns an updated version of the page showing the new set of list items. One client is reporting that IE is displaying friendly error messages when the page updates itself instead of the correct behavior of displaying the updated page. Turning friendly error messages off "corrects" this problem, and displays the updated page normally, indicating no actual server error occurred. When testing from any location other than this client's our web app does not produce any http error statuses, and in this specific situation only produces 200 statuses. (According to Fiddler.) What could be interfering with the HTTP POST and changing the response's http status code to 500 (or another code that would trigger friendly errors in IE)? Are there certain proxies or other network tools that could be misconfigured or buggy in this manner? Is there any way we can alter our application (apart from avoiding posts to the same script, which is not feasible) to get around this misbehavior?

  • Fade in an HTML element with raw javascript over 500 miliseconds.

    - by Juan C. Rois
    Hello everybody, Once again I find myself stuck by something that I just don't understand. Any help would be appreciated. I'm working on a modal window, you click something and the background is masked and a modal window shows some content. I have a div with "display:none" and "opacity:0", and when the user triggers the modal, this div will overlay everything and have certain transparency to it. In my mind, what I need to do is: Set the opacity Perform a "for" loop that will check if the opacity is less than the desired value. Inside this loop, perform a "setInterval" to gradually increment the value of the opacity until it reaches the desired value. When the desired value has been reached, perform an "if" statement to "clearInterval". My code so far is as follows: var showMask = document.getElementById('mask'); function fireModal(){ showMask.style.opacity = 0; showMask.style.display = 'block'; var getCurrentOpacity = showMask.style.opacity; var increaseOpacity = 0.02; var finalOpacity = 0.7; var intervalIncrement = 20; var timeLapse = 500; function fadeIn(){ for(var i = getCurrentOpacity; i < finalOpacity; i++){ setInterval(function(){ showMask.style.opacity = i; }, intervalIncrement) } if(getCurrentOpacity == finalOpacity){ clearInterval(); } } fadeIn(); } As you all can guess, this is not working, all it does is set the opacity to "1" without gradually fade it in. Thanks in advance for your help.

  • 500 - An error has occurred! DB function reports no errors when adding new article in Joomla!

    - by Roland
    I have an article that I want to publish on my Joomla! site. Every time I click apply or save. I get error 500 - An error has occurred! DB function reports no errors. I have no idea why this error comes up, al I can think is that it's a server error. I'm using TinyMCE to type articles together with Joomla! 1.5.11. Updated: I turned on Maximum error reporting in Joomla! and in the article manager I tried to save the article and got these couple of errors. Please check screenshot I tried adding <?php ini_set('error_reporting', E_ALL); error_reporting(E_ALL); ini_set('log_errors',TRUE); ini_set('html_errors',TRUE); ini_set('display_errors',true); ?> at the top of the index.php pages for Joomla! but it does not show any errors. I checked the error logs on the server and also no errors come up. I managed to publish the article via phpMyAdmin but then something else happens. I try to access to article from the front end, by clicking on the link to the article, but only a blank page comes up. This is really weird, since the error log does not show any information. So I assume the error needs to be coming from Joomla! This happens if I add a print_r($_POST) before if (!$row->check()) { on /administrator/components/com_content/controller.php (around line 693) Array ( [title] => Test. [state] => 0 [alias] => test [frontpage] => 0 [sectionid] => 10 [catid] => 44 [details] => Array ( [created_by] => 62 [created_by_alias] => [access] => 0 [created] => 2008-10-25 13:31:21 [publish_up] => 2008-10-25 13:31:21 [publish_down] => Never ) [params] => Array ( [show_title] => [link_titles] => [show_intro] => [show_section] => [link_section] => [show_category] => [link_category] => [show_vote] => [show_author] => 1 [show_create_date] => 0 [show_modify_date] => 0 [show_pdf_icon] => [show_print_icon] => [show_email_icon] => [language] => [keyref] => [readmore] => ) [meta] => Array ( [description] => Test.

  • Kill UDP port that has no process?

    - by Chocohound
    I can't bind to UDP port 500 from my code (yes I'm running w/ sudo). The port is reported as "already in use" (Mac os X), but doesn't have an associated process: $ sudo netstat -na | grep "udp.*\.500\>" udp4 0 0 192.168.50.181.500 *.* udp4 0 0 192.168.29.166.500 *.* But sudo lsof doesn't show a process on port 500 (ie sudo lsof -i:500 -P reports nothing). How can I unbind port 500 so I can use it again? I believe I have a bad VPN client that isn't cleaning up after itself, but I can't get rid of this without rebooting the machine.

  • I’m new to C++ and unsure about how to improve this code [migrated]

    - by Laian Alsabbagh
    The purpose of the following code is to get a random number of 100 nodes and to distribute these nodes randomly in range 500*500 …(X,Y).. this was the first step #include<iostream> #include <fstream> #include<cmath> using namespace std; int main() { const int x = 0, y = 1; int nodes[100][2]; ofstream myfile; myfile.open ("example.txt"); myfile << "Writing this to a file.\n"; for (int i=0; i<100 ;i++) { nodes[i][x] = rand() % 501; nodes[i][y] = rand() % 501; myfile <<nodes[i][x]<<" "<<nodes[i][y]; } myfile.close(); } now the next step is to improve this code to distribute these nodes in order ( "Imust divide both xy_coordinates as : x= 0-100-200-300-400-500 & y=0-100-200-300-400-500) next is to distribute the nodes (regardless number of nodes) in order range Starting from (0,100 )….(100,100)..(100,200)…….untile i reach the last point (500,500),, ") I’m really confused of how to do it correctly I start to think to define 2 dimensional array , and then to define 2 for loops enter code here Int no_nodes=100; Int XY_coordinate [500][500]; For (int i=0;i<no_nodes; i++) { For (int j=0;j<no_nodes; j++)

  • Atmospheric scattering sky from space artifacts

    - by ollipekka
    I am in the process of implementing atmospheric scattering of a planets from space. I have been using Sean O'Neil's shaders from http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter16.html as a starting point. I have pretty much the same problem related to fCameraAngle except with SkyFromSpace shader as opposed to GroundFromSpace shader as here: http://www.gamedev.net/topic/621187-sean-oneils-atmospheric-scattering/ I get strange artifacts with sky from space shader when not using fCameraAngle = 1 in the inner loop. What is the cause of these artifacts? The artifacts disappear when fCameraAngle is limtied to 1. I also seem to lack the hue that is present in O'Neil's sandbox (http://sponeil.net/downloads.htm) Camera position X=0, Y=0, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. Camera position X=500, Y=500, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. I've found that the camera angle seems to handled very differently depending the source: In the original shaders the camera angle in SkyFromSpaceShader is calculated as: float fCameraAngle = dot(v3Ray, v3SamplePoint) / fHeight; Whereas in ground from space shader the camera angle is calculated as: float fCameraAngle = dot(-v3Ray, v3Pos) / length(v3Pos); However, various sources online tinker with negating the ray. Why is this? Here is a C# Windows.Forms project that demonstrates the problem and that I've used to generate the images: https://github.com/ollipekka/AtmosphericScatteringTest/ Update: I have found out from the ScatterCPU project found on O'Neil's site that the camera ray is negated when the camera is above the point being shaded so that the scattering is calculated from point to the camera. Changing the ray direction indeed does remove artifacts, but introduces other problems as illustrated here: Furthermore, in the ScatterCPU project, O'Neil guards against situations where optical depth for light is less than zero: float fLightDepth = Scale(fLightAngle, fScaleDepth); if (fLightDepth < float.Epsilon) { continue; } As pointed out in the comments, along with these new artifacts this still leaves the question, what is wrong with the images where camera is positioned at 500, 500, 500? It feels like the halo is focused on completely wrong part of the planet. One would expect that the light would be closer to the spot where the sun should hits the planet, rather than where it changes from day to night. The github project has been updated to reflect changes in this update.

  • Automatic Adjusting Range Table

    - by Bradford
    I have a table with a start date range, an end date range, and a few other additional columns. On input of a new record, I want to automatically adjust any overlapping date ranges (shrinking them to allow for the new input). I also want to ensure that no overlapping records can accidentally be inserted into this table. I'm using Oracle and Java for my application code. How should I enforce the prevention of overlapping date ranges and also allow for automatically adjusting overlapping ranges? Should I create an AFTER INSERT trigger, with a dbms_lock to serialize access, to prevent the overlapping data. Then in Java, apply the logic to auto adjust everything? Or should that part be in PL/SQL in stored procedure call? This is something that we need for a couple other tables so it'd be nice to abstract. If anyone has something like this already written, please share :) I did find this reference: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:474221407101 Here's an example of how each of the 4 overlapping cases should be handled for adjustment on insert: = Example 1 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (20, 50, 'A') Gives (0, 10, 'X') **(20, 50, 'A') **(51, 100, 'Z') (200, 500, 'Y') = Example 2 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (40, 80, 'A') Gives (0, 10, 'X') **(30, 39, 'Z') **(40, 80, 'A') **(81, 100, 'Z') (200, 500, 'Y') = Example 3 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (50, 120, 'A') Gives (0, 10, 'X') **(30, 49, 'Z') **(50, 120, 'A') (200, 500, 'Y') = Example 4 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (20, 120, 'A') Gives (0, 10, 'X') **(20, 120, 'A') (200, 500, 'Y') The algorithm is as follows: given range = g; input range = i; output range set = o if i.start <= g.start if i.end >= g.end o_1 = i else o_1 = i o_2 = (o.end + 1, g.end) else if i.end >= g.end o_1 = (g.start, i.start - 1) o_2 = i else o_1 = (g.start, i.start - 1) o_2 = i o_3 = (i.end + 1, i.end)

  • help setting up an IPSEC vpn from my linux box

    - by robthewolf
    I have an office with a router and a remote server (Linux - Ubuntu 10.10). Both locations need to connect to a data supplier through a VPN. The VPN is an IPSEC gateway. I was able to configure my Linksys rv42 router to create a VPN connection successfully and now I need to do the same for Linux server. I have been messing around with this for too long. First I tried OpenVPN, but that is SSL and not IPSEC. Then I tried Shrew. I think I have the settings correct but I haven't been able to create the connection. It maybe that I have to use something else like a direct IPSEC config or something like that. If someone knows of a way to turn the following settings that I have been given below into a working IPSEC VPN connection I would be very grateful. Here are the settings I was given that must be used to connect to my supplier: Local destination network: 192.168.4.0/24 Local destination hosts: 192.168.4.100 Remote destination network: 192.167.40.0/24 Remote destination hosts: 192.168.40.27 VPN peering point: xxx.xxx.xxx.xxx Then they have given me the following details: IPSEC/ISAKMP Phase 1 Parameters: Authentication method: pre shared secret Diffie Hellman group: group 2 Encryption Algorithm: 3DES Lifetime in seconds:28800 Phase 2 parameters: IPSEC security: ESP Encryption algortims: 3DES Authentication algorithms: MD5 lifetime in seconds: 28800 pfs: disabled Here are the settings from my attempt to use shrew: n:version:2 n:network-ike-port:500 n:network-mtu-size:1380 n:client-addr-auto:0 n:network-frag-size:540 n:network-dpd-enable:1 n:network-notify-enable:1 n:client-banner-enable:1 n:client-dns-used:1 b:auth-mutual-psk:YjJzN2QzdDhyN2EyZDNpNG42ZzQ= n:phase1-dhgroup:2 n:phase1-keylen:0 n:phase1-life-secs:28800 n:phase1-life-kbytes:0 n:vendor-chkpt-enable:0 n:phase2-keylen:0 n:phase2-pfsgroup:-1 n:phase2-life-secs:28800 n:phase2-life-kbytes:0 n:policy-nailed:0 n:policy-list-auto:1 n:client-dns-auto:1 n:network-natt-port:4500 n:network-natt-rate:15 s:client-dns-addr:0.0.0.0 s:client-dns-suffix: s:network-host:xxx.xxx.xxx.xxx s:client-auto-mode:pull s:client-iface:virtual s:client-ip-addr:192.168.4.0 s:client-ip-mask:255.255.255.0 s:network-natt-mode:enable s:network-frag-mode:disable s:auth-method:mutual-psk s:ident-client-type:address s:ident-client-data:192.168.4.0 s:ident-server-type:address s:ident-server-data:192.168.40.0 s:phase1-exchange:aggressive s:phase1-cipher:3des s:phase1-hash:md5 s:phase2-transform:3des s:phase2-hmac:md5 s:ipcomp-transform:disabled Finally here is the debug output from the shrew log: 10/12/22 17:22:18 ii : ipc client process thread begin ... 10/12/22 17:22:18 < A : peer config add message 10/12/22 17:22:18 DB : peer added ( obj count = 1 ) 10/12/22 17:22:18 ii : local address 217.xxx.xxx.xxx selected for peer 10/12/22 17:22:18 DB : tunnel added ( obj count = 1 ) 10/12/22 17:22:18 < A : proposal config message 10/12/22 17:22:18 < A : proposal config message 10/12/22 17:22:18 < A : client config message 10/12/22 17:22:18 < A : local id '192.168.4.0' message 10/12/22 17:22:18 < A : remote id '192.168.40.0' message 10/12/22 17:22:18 < A : preshared key message 10/12/22 17:22:18 < A : peer tunnel enable message 10/12/22 17:22:18 DB : new phase1 ( ISAKMP initiator ) 10/12/22 17:22:18 DB : exchange type is aggressive 10/12/22 17:22:18 DB : 217.xxx.xxx.xxx:500 <- 206.xxx.xxx.xxx:500 10/12/22 17:22:18 DB : c1a8b31ac860995d:0000000000000000 10/12/22 17:22:18 DB : phase1 added ( obj count = 1 ) 10/12/22 17:22:18 : security association payload 10/12/22 17:22:18 : -

  • How can I implement lazy loading on a page with 500+ images?

    - by Fedor
    I basically have a booking engine unit results page which must show 40 units and per each unit there's 1 large image of the first thumbnail and an X number of accompanying thumbnail images. I've been using the jquery lazy load plugin, but it's not thorough enough ( I'm invoking it on DOM Ready ), plus it doesn't really work in IE ( 50% of the clients use IE so it's a big issue ). What I think I really need to do is not really spit out the image but a fake element such as a span, and possibly modify my code such that if the user views the span, render it into an image element. <span src="/images/foo.gif"> The booking engine relies on JS so I think I might be forced to just rely on ajaxifying all the thumbnails and have event handlers on window scroll, etc in order for the page to be "usable" and load at an average time ( 2-3 seconds instead of 5-30s on high speed DSL/Cable ). I'd appreciate any examples or ideas.

  • Minimum-Waste Print Job Grouping Algorithm?

    - by Matt Mc
    I work at a publishing house and I am setting up one of our presses for "ganging", in other words, printing multiple jobs simultaneously. Given that different print jobs can have different quantities, and anywhere from 1 to 20 jobs might need to be considered at a time, the problem would be to determine which jobs to group together to minimize waste (waste coming from over-printing on smaller-quantity jobs in a given set, that is). Given the following stable data: All jobs are equal in terms of spatial size--placement on paper doesn't come into consideration. There are three "lanes", meaning that three jobs can be printed simultaneously. Ideally, each lane has one job. Part of the problem is minimizing how many lanes each job is run on. If necessary, one job could be run on two lanes, with a second job on the third lane. The "grouping" waste from a given set of jobs (let's say the quantities of them are x, y and z) would be the highest number minus the two lower numbers. So if x is the higher number, the grouping waste would be (x - y) + (x - z). Otherwise stated, waste is produced by printing job Y and Z (in excess of their quantities) up to the quantity of X. The grouping waste would be a qualifier for the given set, meaning it could not exceed a certain quantity or the job would simply be printed alone. So the question is stated: how to determine which sets of jobs are grouped together, out of any given number of jobs, based on the qualifiers of 1) Three similar quantities OR 2) Two quantities where one is approximately double the other, AND with the aim of minimal total grouping waste across the various sets. (Edit) Quantity Information: Typical job quantities can be from 150 to 350 on foreign languages, or 500 to 1000 on English print runs. This data can be used to set up some scenarios for an algorithm. For example, let's say you had 5 jobs: 1000, 500, 500, 450, 250 By looking at it, I can see a couple of answers. Obviously (1000/500/500) is not efficient as you'll have a grouping waste of 1000. (500/500/450) is better as you'll have a waste of 50, but then you run (1000) and (250) alone. But you could also run (1000/500) with 1000 on two lanes, (500/250) with 500 on two lanes and then (450) alone. In terms of trade-offs for lane minimization vs. wastage, we could say that any grouping waste over 200 is excessive. (End Edit) ...Needless to say, quite a problem. (For me.) I am a moderately skilled programmer but I do not have much familiarity with algorithms and I am not fully studied in the mathematics of the area. I'm I/P writing a sort of brute-force program that simply tries all options, neglecting any option tree that seems to have excessive grouping waste. However, I can't help but hope there's an easier and more efficient method. I've looked at various websites trying to find out more about algorithms in general and have been slogging my way through the symbology, but it's slow going. Unfortunately, Wikipedia's articles on the subject are very cross-dependent and it's difficult to find an "in". The only thing I've been able to really find would seem to be a definition of the rough type of algorithm I need: "Exclusive Distance Clustering", one-dimensionally speaking. I did look at what seems to be the popularly referred-to algorithm on this site, the Bin Packing one, but I was unable to see exactly how it would work with my problem. Any help is appreciated. :)

  • Is it possible to make a MS-SQL Scalar function do this?

    - by Hokken
    I have a 3rd party application that can call a MS-SQL scalar function to return some summary information from a table. I was able to return the summary values with a table-valued function, but the application won't utilize table-valued functions, so I'm kind of stuck. Here's a sample from the table: trackingNumber, projTaskAward, expenditureType, amount 1122, 12345-67-89, Supplies, 100 1122, 12345-67-89, Supplies, 150 1122, 12345-67-89, Supplies, 250 1122, 12345-67-89, Misc, 50 1122, 12345-67-89, Misc, 100 1122, 98765-43-21, General, 200 1122, 98765-43-21, Conference, 500 1122, 98765-43-21, Misc, 300 1122, 98765-43-21, Misc, 100 1122, 98765-43-21, Misc, 100 I want to summarize the amounts by projTaskAward & expenditureType, based on the trackingNumber. Here is the output I'm looking for: Proj/Task/Award: 12345-67-89 Expenditure Type: Supplies Total: 500 Proj/Task/Award: 12345-67-89 Expenditure Type: Misc Total: 150 Proj/Task/Award: 98765-43-21 Expenditure Type: General Total: 200 Proj/Task/Award: 98765-43-21 Expenditure Type: Conference Total: 500 Proj/Task/Award: 98765-43-21 Expenditure Type: Misc Total: 500 I'd appreciate any help anyone can give in steering me in the right direction.

  • Expand a volume residing on one X-RAID disk installed on a Netgear ReadyNas Duo v2

    - by Sid
    I've got a Netgear ReadyNas Duo v2 (2 disk slots). System is configured with X-RAID which does not provide flexibility but automatically expands based on a sort of RAID-5 logic. I had 2 500 GB hard disk installed, redundant, so I had 500 GB of volume size. I wanted to upgrade the whole system to 3 GB * 2 hard disk maintaining both the data already on the NAS and the data on one of the two 3 TB hard disks. So I did this: Unplugged one disk from the ReadyNas. Now the readynas has 1*500 GB non redundant. Plugged one empty 3 TB hard disk. Now the readynas has 1*500 GB + 1*3 TB, redundant. I waited for the resync. I then unplugged the 500 GB hard disk, so that I have only the 3 TB hard disk with the previous data. Now what I want is to copy the data on my other 3 TB hard disk in the NAS, so that I can plug this other disk in the NAS and use it for redundancy. The problem is that: the NAS has the (single) 3 TB hard disk in X-RAID, but the volume does not expand to 3 TB, it remains fixed to 500 GB. Is there a way to tell the ReadyNas to force expanding the volume to the whole disk without plugging in another hard disk of the same size?

  • jquery delay() doesn't delay attr() in the queue

    - by luca
    hi, what is wrong in this code? I'm trying to get this effect: fadeOut(500) and attr('class','myClass') delayed by 600 millisecs.. then delay(600) again, and fadeIn(500). The delays happen correctly but the attr() is not being delayed, it fires when #myDiv is still fading! :'( $('#myDiv').fadeOut(500).delay(600).attr('class','myClass').delay(600).fadeIn(500); many thanks in advance for any suggestions!

  • Why is numpy's einsum faster than numpy's built in functions?

    - by Ophion
    Lets start with three arrays of dtype=np.double. Timings are performed on a intel CPU using numpy 1.7.1 compiled with icc and linked to intel's mkl. A AMD cpu with numpy 1.6.1 compiled with gcc without mkl was also used to verify the timings. Please note the timings scale nearly linearly with system size and are not due to the small overhead incurred in the numpy functions if statements these difference will show up in microseconds not milliseconds: arr_1D=np.arange(500,dtype=np.double) large_arr_1D=np.arange(100000,dtype=np.double) arr_2D=np.arange(500**2,dtype=np.double).reshape(500,500) arr_3D=np.arange(500**3,dtype=np.double).reshape(500,500,500) First lets look at the np.sum function: np.all(np.sum(arr_3D)==np.einsum('ijk->',arr_3D)) True %timeit np.sum(arr_3D) 10 loops, best of 3: 142 ms per loop %timeit np.einsum('ijk->', arr_3D) 10 loops, best of 3: 70.2 ms per loop Powers: np.allclose(arr_3D*arr_3D*arr_3D,np.einsum('ijk,ijk,ijk->ijk',arr_3D,arr_3D,arr_3D)) True %timeit arr_3D*arr_3D*arr_3D 1 loops, best of 3: 1.32 s per loop %timeit np.einsum('ijk,ijk,ijk->ijk', arr_3D, arr_3D, arr_3D) 1 loops, best of 3: 694 ms per loop Outer product: np.all(np.outer(arr_1D,arr_1D)==np.einsum('i,k->ik',arr_1D,arr_1D)) True %timeit np.outer(arr_1D, arr_1D) 1000 loops, best of 3: 411 us per loop %timeit np.einsum('i,k->ik', arr_1D, arr_1D) 1000 loops, best of 3: 245 us per loop All of the above are twice as fast with np.einsum. These should be apples to apples comparisons as everything is specifically of dtype=np.double. I would expect the speed up in an operation like this: np.allclose(np.sum(arr_2D*arr_3D),np.einsum('ij,oij->',arr_2D,arr_3D)) True %timeit np.sum(arr_2D*arr_3D) 1 loops, best of 3: 813 ms per loop %timeit np.einsum('ij,oij->', arr_2D, arr_3D) 10 loops, best of 3: 85.1 ms per loop Einsum seems to be at least twice as fast for np.inner, np.outer, np.kron, and np.sum regardless of axes selection. The primary exception being np.dot as it calls DGEMM from a BLAS library. So why is np.einsum faster that other numpy functions that are equivalent? The DGEMM case for completeness: np.allclose(np.dot(arr_2D,arr_2D),np.einsum('ij,jk',arr_2D,arr_2D)) True %timeit np.einsum('ij,jk',arr_2D,arr_2D) 10 loops, best of 3: 56.1 ms per loop %timeit np.dot(arr_2D,arr_2D) 100 loops, best of 3: 5.17 ms per loop The leading theory is from @sebergs comment that np.einsum can make use of SSE2, but numpy's ufuncs will not until numpy 1.8 (see the change log). I believe this is the correct answer, but have not been able to confirm it. Some limited proof can be found by changing the dtype of input array and observing speed difference and the fact that not everyone observes the same trends in timings.

  • MySQL Query to find consecutive available times of variable lenth

    - by Armaconn
    I have an events table that has user_id, date ('2013-10-01'), time ('04:15:00'), and status_id; What I am looking to find is a solution similar to http://stackoverflow.com/questions/2665574/find-consecutive-rows-calculate-duration but I need I need two additional components: 1) Take date into consideration, so 10/1/2013 at 11:00 PM - 10/2/2013 at 3:00AM. Feel free to just put in a fake date range (like '2013-10-01' to '2013-10-31') 2) Limit output to only include when there are 4+ consecutive times (each event is 15 minutes and I want it to display minimum blocks of an hour, but would also like to be able to switch this restriction to 1.5 hours or some other duration if possible).

  • Shuffling a list with a constraint

    - by 500
    Preparing a new psychophysic experiment, I have 48 original stimuli displayed 4 times (4 conditions). Resulting in 192 trials. Trying to randomize the order of presentation during the experiment, I need to maximize the distance between the 4 display of the same original stimuli. Please Consider : Table[{j, i}, {j, Range[48]}, {i, Range[4]}] Where j is the original stimuli number and i the condition Output Sample : {{1, 1}, {1, 2}, {1, 3}, {1, 4}, {2, 1}, {2, 2}, {2, 3}, {2, 4}, ... {47, 1}, {47, 2}, {47, 3},{47, 4}, {48, 1}, {48, 2}, {48, 3}, {48, 4}} How could I shuffle the order of presentation of those 192 items, maximizing the distance between identical item with regard to j the original stimuli number ?
