• Corrupt mercurial repository - cannot update

  Hi all, i think ive managed to corrupt one of mercurial repositories, is there anyway to recover the damage? the message i get when attempting to update the repo to my default branch is: PS C:\wco\projects\ims\code> hg up -C default abort: data/Trunk/application/models/priority_model.php.i@83dbdfb60981: no match found! when i run hg verify, i get the following report: PS C:\wco\projects\ims\code> hg verify checking changesets checking manifests crosschecking files in changesets and manifests checking files data/.buildpath.i@0: missing revlog! 0: empty or missing .buildpath .buildpath@0: daf15acb5273 in manifests not found data/.project.i@0: missing revlog! 0: empty or missing .project .project@0: e8b25997d6d1 in manifests not found Rawlings IMS/index.html@3: empty or missing copy source revlog index.html:b8b2b36a6eea Rawlings IMS/index.php@3: empty or missing copy source revlog index.php:a5f76bf232e9 Rawlings IMS/index_backup.php@3: empty or missing copy source revlog index_backup.php:a5f76bf232e9 Rawlings IMS/index_this_hold.html@3: empty or missing copy source revlog index_this_hold.html:b8b2b36a6eea Rawlings IMS/testera.php@3: empty or missing copy source revlog testera.php:6e9e3666c1bc Trunk/application/models/priority_model.php@32: 83dbdfb60981 in manifests not found data/index.html.i@0: missing revlog! 0: empty or missing index.html index.html@0: b8b2b36a6eea in manifests not found data/index.php.i@0: missing revlog! 0: empty or missing index.php index.php@0: a5f76bf232e9 in manifests not found data/index_backup.php.i@0: missing revlog! 0: empty or missing index_backup.php index_backup.php@0: a5f76bf232e9 in manifests not found data/index_this_hold.html.i@0: missing revlog! 0: empty or missing index_this_hold.html index_this_hold.html@0: b8b2b36a6eea in manifests not found data/nbproject/project.properties.i@14: missing revlog! 14: empty or missing nbproject/project.properties nbproject/project.properties@14: 1efa3074378b in manifests not found data/nbproject/project.xml.i@14: missing revlog! 14: empty or missing nbproject/project.xml nbproject/project.xml@14: 52689bf2b35a in manifests not found data/rcrawley/.buildpath.i@9: missing revlog! 9: empty or missing rcrawley/.buildpath rcrawley/.buildpath@9: 2c6411d4fcff in manifests not found data/rcrawley/.project.i@9: missing revlog! 9: empty or missing rcrawley/.project rcrawley/.project@9: cb4b1495acab in manifests not found data/rcrawley/assets/images/ajax-loader.gif.i@9: missing revlog! 9: empty or missing rcrawley/assets/images/ajax-loader.gif rcrawley/assets/images/ajax-loader.gif@9: 8ef26516c7da in manifests not found data/rcrawley/index.html.i@9: missing revlog! 9: empty or missing rcrawley/index.html rcrawley/index.html@9: 545246299dee in manifests not found data/rcrawley/index.php.i@9: missing revlog! 9: empty or missing rcrawley/index.php rcrawley/index.php@9: 66eac798ed6d in manifests not found data/rcrawley/index_backup.php.i@9: missing revlog! 9: empty or missing rcrawley/index_backup.php rcrawley/index_backup.php@9: 93971228fbf5 in manifests not found data/rcrawley/system/index.html.i@9: missing revlog! 9: empty or missing rcrawley/system/index.html rcrawley/system/index.html@9: 17360d3b566e in manifests not found data/rcrawley/testera.php.i@9: missing revlog! 9: empty or missing rcrawley/testera.php rcrawley/testera.php@9: 7d9bd5196740 in manifests not found data/testera.php.i@0: missing revlog! 0: empty or missing testera.php testera.php@0: 6e9e3666c1bc in manifests not found 1646 files, 59 changesets, 1897 total revisions 57 integrity errors encountered!

• Set up linux box for hosting a-z

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP/MySQL: To upgrade PHP and MySQL to the latest versions, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! Add IUS repository to our package manager cd /tmp wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. # list all the packages in the IUS repository; use this to find PHP/MySQL version and libraries you want to install Remove old version of PHP and install newer version from IUS rpm -qa | grep php # to list all of the installed php packages we want to remove yum shell # open an interactive yum shell remove php-common php-mysql php-cli #remove installed PHP components install php53 php53-mysql php53-cli php53-common #add packages you want transaction solve #important!! checks for dependencies transaction run #important!! does the actual installation of packages.

• Cluster failover and strange gratuitous arp behavior

  - by lazerpld

  I am experiencing a strange Windows 2008R2 cluster related issue that is bothering me. I feel that I have come close as to what the issue is, but still don't fully understand what is happening. I have a two node exchange 2007 cluster running on two 2008R2 servers. The exchange cluster application works fine when running on the "primary" cluster node. The problem occurs when failing over the cluster ressource to the secondary node. When failing over the cluster to the "secondary" node, which for instance is on the same subnet as the "primary", the failover initially works ok and the cluster ressource continues to work for a couple of minutes on the new node. Which means that the recieving node does send out a gratuitous arp reply packet that updated the arp tables on the network. But after x amount of time (typically within 5 minutes time) something updates the arp-tables again because all of a sudden the cluster service does not answer to pings. So basically I start a ping to the exchange cluster address when its running on the "primary node". It works just great. I failover the cluster ressource group to the "secondary node" and I only have loss of one ping which is acceptable. The cluster ressource still answers for some time after being failed over and all of a sudden the ping starts timing out. This is telling me that the arp table initially is updated by the secondary node, but then something (which I haven't found out yet) wrongfully updates it again, probably with the primary node's MAC. Why does this happen - has anyone experienced the same problem? The cluster is NOT running NLB and the problem stops immidiately after failing over back to the primary node where there are no problems. Each node is using NIC teaming (intel) with ALB. Each node is on the same subnet and has gateway and so on entered correctly as far as I am concerned. Edit: I was wondering if it could be related to network binding order maybe? Because I have noticed that the only difference I can see from node to node is when showing the local arp table. On the "primary" node the arp table is generated on the cluster address as the source. While on the "secondary" its generated from the nodes own network card. Any input on this? Edit: Ok here is the connection layout. Cluster address: A.B.6.208/25 Exchange application address: A.B.6.212/25 Node A: 3 physical nics. Two teamed using intels teaming with the address A.B.6.210/25 called public The last one used for cluster traffic called private with 10.0.0.138/24 Node B: 3 physical nics. Two teamed using intels teaming with the address A.B.6.211/25 called public The last one used for cluster traffic called private with 10.0.0.139/24 Each node sits in a seperate datacenter connected together. End switches being cisco in DC1 and NEXUS 5000/2000 in DC2. Edit: I have been testing a little more. I have now created an empty application on the same cluster, and given it another ip address on the same subnet as the exchange application. After failing this empty application over, I see the exact same problem occuring. After one or two minutes clients on other subnets cannot ping the virtual ip of the application. But while clients on other subnets cannot, another server from another cluster on the same subnet has no trouble pinging. But if i then make another failover to the original state, then the situation is the opposite. So now clients on same subnet cannot, and on other they can. We have another cluster set up the same way and on the same subnet, with the same intel network cards, the same drivers and same teaming settings. Here we are not seeing this. So its somewhat confusing. Edit: OK done some more research. Removed the NIC teaming of the secondary node, since it didnt work anyway. After some standard problems following that, I finally managed to get it up and running again with the old NIC teaming settings on one single physical network card. Now I am not able to reproduce the problem described above. So it is somehow related to the teaming - maybe some kind of bug? Edit: Did some more failing over without being able to make it fail. So removing the NIC team looks like it was a workaround. Now I tried to reestablish the intel NIC teaming with ALB (as it was before) and i still cannot make it fail. This is annoying due to the fact that now i actually cannot pinpoint the root of the problem. Now it just seems to be some kind of MS/intel hick-up - which is hard to accept because what if the problem reoccurs in 14 days? There is a strange thing that happened though. After recreating the NIC team I was not able to rename the team to "PUBLIC" which the old team was called. So something has not been cleaned up in windows - although the server HAS been restarted! Edit: OK after restablishing the ALB teaming the error came back. So I am now going to do some thorough testing and i will get back with my observations. One thing is for sure. It is related to Intel 82575EB NICS, ALB and Gratuitous Arp.

• Someone please help google create instuctions that windows users understand. googles "instructions"

  - by nathan

  Below are the only instructions i managed to find from google on how to install the android NDK, it is written as if we all run Linux and presumes we all understand what these obscure tools are. My comments and questions appear in Italics if somone who knows unix and windows would translate for google that would be great! Android NDK Installation Introduction: Please read docs/OVERVIEW.TXT to understand what the Android NDK is and is not. This file gives instructions on how to properly setup your NDK. I. Requirements: The Android NDK currently requires a Linux, OS X or Windows host operating system. Windows users will need to install Cygwin (http://www.cygwin.com) to use it. Note that running the NDK under MSys is not supported. You will need to have the Android SDK and its dependencies installed. The NDK cannot generate final application packages (.apk files), only the shared library files that can go into them. IMPORTANT: The Android NDK can only be used to target system images using the Cupcake (1.5) or later releases of the platform. This is due to subtle toolchain and ABI related changed that make it incompatible with 1.0 and 1.1 system images. The NDK requires GNU Make 3.81 or later being available on your development system. Earlier versions of GNU Make might work but have not been tested. You can check this by running 'make -v' from the command-line. The output should look like: GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc. ... On certain systems, GNU Make might be available through a different command like 'gmake' or 'gnumake'. For these systems, replace 'make' by the appropriate command when invoking the NDK build system as described in the documentation. Great some strange thing called gnu make.. if your not going to tell me what it does maybe you then at least you could give me a URL to it? The NDK also requires a Nawk or GNU Awk executable being available on your development system. Note that the original 'awk' program doesn't implement the 'match' and 'substr' functions used by the NDK build system. Ok another tool, with 1 of 2 possible names, but not the third... and again where should i download this?? On Windows, you will need to install a recent release of Cygwin to use the NDK. See http://www.cygwin.com for instructions. Woohoo a URL! download took about a day because these install instructions do not specify what parts to download. II. Preparing your installation prebuilt cross-toolchain binaries: After installing and unarchiving the NDK, you will need to run the following command from the root folder: build/host-setup.sh hello? windows dont run nothing but .exe .com or .dll, just tell me how you want me to run it.. This will test your setup and make sure the NDK can work properly. Nothing is said about where any of these things need to be installed to (what directory)

• How do I make these fields autopopulate from the database?

  - by dmanexe

  I have an array, which holds values like this: $items_pool = Array ( [0] => Array ( [id] => 1 [quantity] => 1 ) [1] => Array ( [id] => 2 [quantity] => 1 ) [2] => Array ( [id] => 72 [quantity] => 6 ) [3] => Array ( [id] => 4 [quantity] => 1 ) [4] => Array ( [id] => 5 [quantity] => 1 ) [5] => Array ( [id] => 7 [quantity] => 1 ) [6] => Array ( [id] => 8 [quantity] => 1 ) [7] => Array ( [id] => 9 [quantity] => 1 ) [8] => Array ( [id] => 19 [quantity] => 1 ) [9] => Array ( [id] => 20 [quantity] => 1 ) [10] => Array ( [id] => 22 [quantity] => 1 ) [11] => Array ( [id] => 29 [quantity] => 0 ) ) Next, I have a form that I am trying to populate. It loops through the item database, prints out all the possible items, and checks the ones that are already present in $items_pool. <?php foreach ($items['items_poolpackage']->result() as $item): ?> <input type="checkbox" name="measure[<?=$item->id?>][checkmark]" value="<?=$item->id?>"> <?php endforeach; ?> I know what logically I'm trying to accomplish here, but I can't figure out the programming. What I'm looking for, written loosely is something like this (not real code): <input type="checkbox" name="measure[<?=$item->id?>][checkmark]" value="<?=$item->id?>" <?php if ($items_pool['$item->id']) { echo "SELECTED"; } else { }?>> Specifically this conditional loop through the array, through all the key values (the ID) and if there's a match, the checkbox is selected. <?php if ($items_pool['$item->id']) { echo "SELECTED"; } else { }?> I understand from a loop structured like this that it may mean a lot of 'extra' processing. TL;DR - I need to echo within a loop if the item going through the loop exists within another array.

• Issue with XSL Criteria

  - by Rachel

  I am using the below piece of XSL to select the id of the text nodes whose content has a given index. This index value in input will be relative to a spcified node whose id value is known. The criteria to select the text node is, The text node content should contain a index say 'i' relative to node say 'n' whose id value i know. 'i' and 'id of n' is got as index and nodeName from the input param as seen in the xsl. Node 'd1e5' has the text content whose index ranges from 1 to 33. When i give an index value greater than 33 i want the below criteria to fail but it does not, [sum((preceding::text(), .)[normalize-space()][. >> //*[@id=$nodeName]]/string-length(.)) ge $index] Input xml: <?xml version="1.0" encoding="UTF-8"?> <html xmlns="http://www.w3.org/1999/xhtml" id="d1e1"> <head id="d1e3"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title id="d1e5">Every document must have a title</title> </head> <body id="d1e9"> <h1 id="d1e11" align="center">Very Important Heading</h1> <p id="d1e13">Since this is just a sample, I won't put much text here.</p> </body> </html> XSL code used: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsd="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xsd" version="2.0"> <xsl:param name="insert-file" as="node()+"> <insert-data><data index="1" nodeName="d1e5"></data><data index="34" nodeName="d1e5"></data></insert-data> </xsl:param> <xsl:param name="nodeName" as="xsd:string" /> <xsl:variable name="main-root" as="document-node()" select="/"/> <xsl:variable name="insert-data" as="element(data)*"> <xsl:for-each select="$insert-file/insert-data/data"> <xsl:sort select="xsd:integer(@index)"/> <xsl:variable name="index" select="xsd:integer(@index)" /> <xsl:variable name="nodeName" select="@nodeName" /> <data text-id="{generate-id($main-root/descendant::text()[sum((preceding::text(), .)[normalize-space()][. >> //*[@id=$nodeName]]/string-length(.)) ge $index][1])}"> </data> </xsl:for-each> </xsl:variable> <xsl:template match="/"> <Output> <xsl:copy-of select="$insert-data" /> </Output> </xsl:template> </xsl:stylesheet> Actual output: <?xml version="1.0" encoding="UTF-8"?> <Output> <data text-id="d1t8"/> <data text-id="d1t14"/> </Output> Expected output: <?xml version="1.0" encoding="UTF-8"?> <Output> <data text-id="d1t8"/> </Output> This solution works fine if index lies between 1 and 33. Any index value greater that 33 causes incorrect text nodes to get selected. I could not understand why the text node 'd1t14' is getting selected. Please share your thoughts.

• fonts mac vs pc

  - by Kieran

  Hi all hope your having a good day/evening. Simple question, but maybe not so simple to answer. I have an unordered list, which i am using as a menu. The list items are floated right and sized due to an anchor tag inside them with a roll over. The last element is given a specific size to suck up any extra space. See the code snippits bellow. css ul.mainNav { width: 970px; display:block; background:black; clear:both; overflow:hidden;} ul.mainNav li { float: left; height:29px;} ul.mainNav li a { display: block; padding:7px 19px; color:#ffffff; background-color:#000; font-weight:bold; text-decoration:none; font-size:13px; } ul.mainNav li a:hover, ul.mainNav li a.selected { background-color:#ffff00; color:#000; } ul.mainNav li a.last{ text-align:center; padding: 7px 19px; width:58px;} html <ul class="mainNav" id="mainNav"> <li><a href="/Default.aspx">home</a></li> <li><a href="/About/">about</a></li> <li><a href="/News/">news</a></li> <li><a href="/Enter/Registration.aspx">enter SOYA 2010</a></li> <li><a href="/Categories/Film.aspx">categories</a></li> <li><a href="/Mentors/janChapman.aspx">mentors</a></li> <li><a href="/PastWinners/">past winners</a></li> <li><a href="/Awards/">awards nights</a></li> <li><a href="/Support/" class="last">contact</a></li> </ul> It is containted in a <div style="margin:0 auto;">...</div> to center on the menu on screen Now my problem is: On PC; firefox/ Safari /IE /Chrome are all displaying correctly. Take the same code to a Mac; Safari/ firefox are displaying the menu to be too short and the only thing i can point to is that the fonts may be smaller in widths. The width is currently set to 970px. My question is: How can i get it to display at the same widths without specifying exact widths for each list item? Any help would be appreciated. If my structure is wrong or it is just a mac thing that i will never solve(hope not). Cheers, KJ

• How to set width of parent div in css

  - by Marcin Wiankowski

  I am using vaadin in combination with navigator7 addon. In header and footer there are spacings between conponents That i would not have. I tried to remove the spacings using setSpacing(false) for header and footer component but it is not working probably becouse of the addon. So i tried to solve this using css. The sample below i a test output html that vaadin generates: <!DOCTYPE html> <html> <head> <style type="text/css"> div div .footer-label, .footer-label{ color: green; width: 100px !important; } </style> </head> <body> <div class="my-footer"> <div> <div style="color: red; height: 20px; width: 482px; overflow: hidden; float: left; padding-left: 0px; padding-top: 0px; background-color:yellow;"> <div style="float: left; margin-left: 0px;"> <button class="footer-label" style="width: 400px;">Text</button> </div> </div> </div> </div> </div> </body> </html> There is a button inside div div. I would like to make the width of root div to have exact same width as the button. I ended with this css code but it does not work. The root div stays in its 482 pixels width. div div .footer-label, .footer-label{ color: green; width: 100px !important; } Is it possible to do something like that in css and how to do it? Or how to solve this using problem using Vaadin? Vaadin Code public class MyAppLevelWindow extends HeaderFooterFixedAppLevelWindow { @Override protected Component createHeader() { ... } @Override protected Component createFooter() { HorizontalLayout myFooter = new HorizontalLayout(); akmedFooter.setSpacing(false); akmedFooter.setStyleName("my-footer"); NativeButton sendProblemButton = new NativeButton("Button"); sendProblemButton.setStyleName("footer-label"); akmedFooter.addComponent(sendProblemButton); ..... return akmedFooter; } ............. } Answer .my-footer div div{ width: auto !important; }

• Remote Desktop Services Gateway Issue

  - by AVandelay05

  Alright fellow techies here's the rundown. I have installed Server 2008 r2 Remote Dekstop Services on a VM in my network. I installed the following RD role services: RD Session Host, Licensing, Connection Broker, Gateway, Web Access. When I set things up originally, the gateway server and RDWeb worked as it should locally. After getting things running locally (remoteserver.domainname.local) I wanted to test things externally. From the outside, I couldn't get things running (meaning I could connect to rdweb access externally, but when I tried to run an app I would get the message "can't connect/find computer"). Here's my setup for external access The VM has every RD Services role services installed on it, meaning it acts as gateway, rd web access, session host, licensing, the whole bit. I made a self-signed certificate on the gateway server (gateway.domainname.net is the cert name). Internally, I have a secondary forward-lookup zone called domainname.net with an A record gateway pointing to the local IP of the gateway server. On our public DNS (domainname.net) I have an A record gateway. This is to access the RDWeb externally. In IIS I have the following authentication settings RDWeb: All disabled except for anonymous authentication Rpc: All disabled except for basic and windows RpcWithCert: All disbled except for windows authentication I have the necessary web access config in our sonicwall tz210 (https and rdp, external ip pointing to local ip of rds server) RAP and CAP have the correct user and computer groups, authentication, and allowed devices After all of this, here's what happens accessing externally. I can login correctly to RDWeb Access (I've tried a bogus login, I can't login to it so that's working properly). I see the Apps for use. I click on an app, click connect, the credential window opens, I put in the correct user creds, it tries to connect to the gateway server, but then the cred window comes back in view. I tried to reach a limit of failed logins, but never reached one, haha. So from the same external client machine I try to connect to the gateway through a Remote Desktop connection. I put in the correct gateway settings in the RD window, try to connect and get the same results as I did in RDWeb access. I checked the event logs on the RD Services machine and saw the following event IDs around the time I tried to login externally: ID 6037 with the message "The program svchost.exe, with the assigned process ID 2168, could not authenticate locally by using the target name host/gateway.domainname.net. The target name used is not valid. A target name should refer to one of the local computer names, for example, the DNS host name. Try a different target name." ID 10 RADWebAccess "RD Web Access was unable to access gateway.domainname.net, which is the server that is specified as running the RemoteApp and Desktop Connection Management service. Ensure that the computer account of the RD Web Access server is a member of the TS Web Access Computers security group on gateway.domainname.net" ID 4625 "An account failed to log on. Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: Administrator Account Domain: gateway.domainname.net Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc000006a Process Information: Caller Process ID: 0x0 Caller Process Name: - Network Information: Workstation Name: USER-LAPTOP Source Network Address: External IP Source Port: 63125 Detailed Authentication Information: Logon Process: NtLmSsp Authentication Package: NTLM Transited Services: - Package Name (NTLM only): - Key Length: 0 This event is generated when a logon request fails. It is generated on the computer where access was attempted. The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network). The Process Information fields indicate which account and process on the system requested the logon. The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols." I don't think the VM has a null SID. The SID of the VM and it's physical host have different SIDS. I can access the blank page for rpc externally using the external gateway name. It seems like authentication is a problem. Also, is it a problem that the external name of the gateway server doesn't match the local name? The external name (which the cert is based on) is gateway.domainname.net and the internal name is remoteserver.domainname.local. That's the only thing I can think of that would be the problem, but the external name has to be different from the local right? Internally, I ping gateway.domainname.net and it gives me the correct local IP of the server. Now, there isn't an actual computer name in AD, but I don't know how I would achieve that? I hope I've been clear....any help would be appreciated. I think I'm close to achieving this. :)

• Help with this code.

  Heading ##Hey guys i need help with this code.The short version is,i have to do match the follwing by using drag and drop in jquery and later i need to show a message whether it is right or wrong. var output = "Wrong"; var old_item ; var new_item ; var newObjArray=[]; $(function() { var $gallery = $('.gallery'), $trash = $('.trash'); $('div',$gallery).draggable({ revert: 'invalid', containment: 'document', helper: 'clone', cursor: 'move', }); // let the trash be droppable, accepting the gallery items $trash.droppable({ //accept: '#gallery div', //activeClass: 'ui-state-highlight', tolerance: 'touch', drop: function(ev, ui) { new_item = ui.draggable; $(this).droppable("option","activeClass",'.ui-state-highlight'); if(contains(newObjArray,ui.draggable)) { newObjArray.pop(ui.draggable); } newObjArray.push(ui.draggable); deleteImage(ui.draggable,$(this)); } }); // let the gallery be droppable as well, accepting items from the trash $gallery.droppable({ //accept: '#trash li', activeClass: 'custom-state-active', drop: function(ev, ui) { recycleImage(ui.draggable); } }); // image deletion function function deleteImage($item,element) { var $list; $item.fadeOut(10,function() { if($(".ui-widget-content", element).length <1){ old_item = $item; $list = $('<div class="gallery ui-helper-reset"/>').appendTo(element); //$('ul',$trash).length ? $('ul',$trash) : $('<ul class="gallery ui-helper-reset"/>').appendTo($trash); $item.appendTo($list).fadeIn(10); } else{ recycleImage($(".ui-widget-content",element)); $list = $('<div class="gallery ui-helper-reset"/>').appendTo(element); $item.appendTo($list).fadeIn(10); old_item = $item; } }); } //check for given answer // image recycle function function recycleImage($item) { $item.fadeOut(10,function() { $item.find("img").end().appendTo($gallery).fadeIn(10); }); } // image preview function, demonstrating the ui.dialog used as a modal window }); function checkOrder(){ if(newObjArray==null){ } else if(newObjArray!=null){ if(newObjArray[0].attr("id")=="5"&& newObjArray[1].attr("id")=="1" && newObjArray[2].attr("id")=="3" && newObjArray[3].attr("id")=="2" && newObjArray[4].attr("id")=="4"){ parent.parent.increaseCorrectA(); } else{ parent.parent.increaseWrongA(); } } } function contains(a, obj) { var i = a.length; while (i--) { if (a[i] === obj) { return true; } } return false; } I am calling the function checkOrder() from the html page after the matching of items is over.What happens here is i have just stored the user responses on the draggable over droppable in an array,based on it's position.It is a bad practice cause,i am saying whether it's right or wrong through its position in the array.The only thing i can do is get the draggable's id present in the droppable.But i dont know how to get that inside the function checkOrder().Any ideas please?

• Explicitly instantiating a generic member function of a generic structure

  - by Dennis Zickefoose

  I have a structure with a template parameter, Stream. Within that structure, there is a function with its own template parameter, Type. If I try to force a specific instance of the function to be generated and called, it works fine, if I am in a context where the exact type of the structure is known. If not, I get a compile error. This feels like a situation where I'm missing a typename, but there are no nested types. I suspect I'm missing something fundamental, but I've been staring at this code for so long all I see are redheads, and frankly writing code that uses templates has never been my forte. The following is the simplest example I could come up with that illustrates the issue. #include <iostream> template<typename Stream> struct Printer { Stream& str; Printer(Stream& str_) : str(str_) { } template<typename Type> Stream& Exec(const Type& t) { return str << t << std::endl; } }; template<typename Stream, typename Type> void Test1(Stream& str, const Type& t) { Printer<Stream> out = Printer<Stream>(str); /****** vvv This is the line the compiler doesn't like vvv ******/ out.Exec<bool>(t); /****** ^^^ That is the line the compiler doesn't like ^^^ ******/ } template<typename Type> void Test2(const Type& t) { Printer<std::ostream> out = Printer<std::ostream>(std::cout); out.Exec<bool>(t); } template<typename Stream, typename Type> void Test3(Stream& str, const Type& t) { Printer<Stream> out = Printer<Stream>(str); out.Exec(t); } int main() { Test2(5); Test3(std::cout, 5); return 0; } As it is written, gcc-4.4 gives the following: test.cpp: In function 'void Test1(Stream&, const Type&)': test.cpp:22: error: expected primary-expression before 'bool' test.cpp:22: error: expected ';' before 'bool' Test2 and Test3 both compile cleanly, and if I comment out Test1 the program executes, and I get "1 5" as I expect. So it looks like there's nothing wrong with the idea of what I want to do, but I've botched something in the implementation. If anybody could shed some light on what I'm overlooking, it would be greatly appreciated.

• Longitudinal Redundancy Check fails

  - by PaulH

  I have an application that decodes data from a magnetic stripe reader. But, I'm having difficulty getting my calculated LRC check byte to match the one on the cards. If I were to grab 3 cards each with 3 tracks, I would guess the algorithm below would work on 4 of the 9 tracks in those cards. The algorithm I'm using looks like this (C#): private static char GetLRC(string s, int start, int end) { int result = 0; for (int i = start; i <= end; i++) { result ^= Convert.ToByte(s[i]); } return Convert.ToChar(result); } This is an example of track 3 data that fails the check. On this card, track 2 matched, but track 1 also failed. 0 1 2 3 4 5 6 7 8 9 A B C D E F 00 3 4 4 4 4 4 4 4 4 4 4 5 5 5 5 5 10 5 5 5 5 5 6 6 6 6 6 6 6 6 6 6 7 20 7 7 7 7 7 7 7 7 7 8 8 8 8 8 8 8 30 8 8 8 9 9 9 9 9 9 9 9 9 9 0 0 0 40 0 0 0 0 0 0 0 1 2 3 4 1 1 1 1 1 50 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 60 3 3 3 3 3 3 3 3 The sector delimiter is ';' and it ends with a '?'. The LRC byte from this track is 0x30. Unfortunately, the algorithm above computes an LRC of 0x00 per the following calculation (apologies for its length. I want to be thorough): 00 ^ 3b = 3b ';' 3b ^ 33 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 34 = 3c 3c ^ 34 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 35 = 3d 3d ^ 35 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 36 = 3e 3e ^ 36 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 37 = 3f 3f ^ 37 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 38 = 30 30 ^ 38 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 39 = 31 31 ^ 39 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 30 = 38 38 ^ 30 = 08 08 ^ 31 = 39 39 ^ 32 = 0b 0b ^ 33 = 38 38 ^ 34 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 31 = 3d 3d ^ 31 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 32 = 3e 3e ^ 32 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 33 = 0c 0c ^ 33 = 3f 3f ^ 3f = 00 '?'

• overloaded stream insetion operator with a vector

  - by julz666

  hi, i'm trying to write an overloaded stream insertion operator for a class who's only member is a vector. i dont really know what i'm doing. (lets make that clear) it's a vector of "Points" which is a struct containing two doubles. i figure what i want is to insert user input (a bunch of doubles) into a stream that i then send to a modifier method? i keep working off other stream insertion examples such as... std::ostream& operator<< (std::ostream& o, Fred const& fred) { return o << fred.i_; } but when i try a similar..... istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr.vertices; return inStream; } i get an error "no match for operator etc etc. if i leave off the .vertices it compiles but i figure it's not right? (vertices is the name of my vector ) and even if it is right, i dont actually know what syntax to use in my driver to use it? also not %100 on what my modifier method needs to look like. here's my Polygon class //header #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); public: //Constructor Polygon(const Point &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return (int) vertices.capacity();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; #endif //Body using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const Point &theVerts) { vertices.push_back (theVerts); } //Copy Constructor Polygon::Polygon(const Polygon &polyCopy) { vertices = polyCopy.vertices; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } any help greatly appreciated, sorry to be so vague, a lecturer has just kind of given us a brief example of stream insertion then left us on our own thanks. oh i realise there are probably many other problems that need fixing

• Policy-based template design: How to access certain policies of the class?

  - by dehmann

  I have a class that uses several policies that are templated. It is called Dish in the following example. I store many of these Dishes in a vector (using a pointer to simple base class), but then I'd like to extract and use them. But I don't know their exact types. Here is the code; it's a bit long, but really simple: #include <iostream> #include <vector> struct DishBase { int id; DishBase(int i) : id(i) {} }; std::ostream& operator<<(std::ostream& out, const DishBase& d) { out << d.id; return out; } // Policy-based class: template<class Appetizer, class Main, class Dessert> class Dish : public DishBase { Appetizer appetizer_; Main main_; Dessert dessert_; public: Dish(int id) : DishBase(id) {} const Appetizer& get_appetizer() { return appetizer_; } const Main& get_main() { return main_; } const Dessert& get_dessert() { return dessert_; } }; struct Storage { typedef DishBase* value_type; typedef std::vector<value_type> Container; typedef Container::const_iterator const_iterator; Container container; Storage() { container.push_back(new Dish<int,double,float>(0)); container.push_back(new Dish<double,int,double>(1)); container.push_back(new Dish<int,int,int>(2)); } ~Storage() { // delete objects } const_iterator begin() { return container.begin(); } const_iterator end() { return container.end(); } }; int main() { Storage s; for(Storage::const_iterator it = s.begin(); it != s.end(); ++it){ std::cout << **it << std::endl; std::cout << "Dessert: " << *it->get_dessert() << std::endl; // ?? } return 0; } The tricky part is here, in the main() function: std::cout << "Dessert: " << *it->get_dessert() << std::endl; // ?? How can I access the dessert? I don't even know the Dessert type (it is templated), let alone the complete type of the object that I'm getting from the storage. This is just a toy example, but I think my code reduces to this. I'd just like to pass those Dish classes around, and different parts of the code will access different parts of it (in the example: its appetizer, main dish, or dessert).

• Update to Easy Slider 1.7 made all my JQuery code stop working.

  - by Anders H

  I'm pretty novice as a JQuery user goes. I've got some experience implementing different plugins but would be lost trying to customize my own. I can't share the exact site details with you due to a NDA, so I hope someone can give me a little help. I've got a project due today (Just HTML/CSS/JQuery). It has a lightbox, show/hide login menu and a slider is Easy Slider 1.5. Everything was working together, until I attempted to update to Easy Slider 1.7 (see link on same page, I'm too new to post more than 1 link). When I did so, JQuery stopped working for all the plugins. I've attempted to revert back to the original state, by undoing my work (didn't do much), ad JQuery remains broken.

• Flash Media Server Streaming: Content Protection

  - by dbemerlin

  Hi, i have to implement flash streaming for the relaunch of our video-on-demand system but either because i haven't worked with flash-related systems before or because i'm too stupid i cannot get the system to work as it has to. We need: Per file & user access control with checks on a WebService every minute if the lease time ran out mid-stream: cancelling the stream rtmp streaming dynamic bandwidth checking Video Playback with Flowplayer (existing license) I've got the streaming and bandwidth check working, i just can't seem to get the access control working. I have no idea how i know which file is played back or how i can play back a file depending on a key the user has entered. Server-Side Code (main.asc): application.onAppStart = function() { trace("Starting application"); this.payload = new Array(); for (var i=0; i < 1200; i++) { this.payload[i] = Math.random(); //16K approx } } application.onConnect = function( p_client, p_autoSenseBW ) { p_client.writeAccess = ""; trace("client at : " + p_client.uri); trace("client from : " + p_client.referrer); trace("client page: " + p_client.pageUrl); // try to get something from the query string: works var i = 0; for (i = 0; i < p_client.uri.length; ++i) { if (p_client.uri[i] == '?') { ++i; break; } } var loadVars = new LoadVars(); loadVars.decode(p_client.uri.substr(i)); trace(loadVars.toString()); trace(loadVars['foo']); // And accept the connection this.acceptConnection(p_client); trace("accepted!"); //this.rejectConnection(p_client); // A connection from Flash 8 & 9 FLV Playback component based client // requires the following code. if (p_autoSenseBW) { p_client.checkBandwidth(); } else { p_client.call("onBWDone"); } trace("Done connecting"); } application.onDisconnect = function(client) { trace("client disconnecting!"); } Client.prototype.getStreamLength = function(p_streamName) { trace("getStreamLength:" + p_streamName); return Stream.length(p_streamName); } Client.prototype.checkBandwidth = function() { application.calculateClientBw(this); } application.calculateClientBw = function(p_client) { /* lots of lines copied from an adobe sample, appear to work */ } Client-Side Code: <head> <script type="text/javascript" src="flowplayer-3.1.4.min.js"></script> </head> <body> <a class="rtmp" href="rtmp://xx.xx.xx.xx/vod_project/test_flv.flv" style="display: block; width: 520px; height: 330px" id="player"> </a> <script> $f( "player", "flowplayer-3.1.5.swf", { clip: { provider: 'rtmp', autoPlay: false, url: 'test_flv' }, plugins: { rtmp: { url: 'flowplayer.rtmp-3.1.3.swf', netConnectionUrl: 'rtmp://xx.xx.xx.xx/vod_project?foo=bar' } } } ); </script> </body> My first Idea was to get a key from the Query String, ask the web service about which file and user that key is for and play the file but i can't seem to find out how to play a file from server side. My second idea was to let flowplayer play a file, pass the key as query string and if the filename and key don't match then reject the connection but i can't seem to find out which file it's currently playing. The only remaining idea i have is: create a list of all files the user is allowed to open and set allowReadAccess or however it was called to allow those files, but that would be clumsy due to the current infrastructure. Any hints? Thanks.

• One letter game problem?

  - by Alex K

  Recently at a job interview I was given the following problem: Write a script capable of running on the command line as python It should take in two words on the command line (or optionally if you'd prefer it can query the user to supply the two words via the console). Given those two words: a. Ensure they are of equal length b. Ensure they are both words present in the dictionary of valid words in the English language that you downloaded. If so compute whether you can reach the second word from the first by a series of steps as follows a. You can change one letter at a time b. Each time you change a letter the resulting word must also exist in the dictionary c. You cannot add or remove letters If the two words are reachable, the script should print out the path which leads as a single, shortest path from one word to the other. You can /usr/share/dict/words for your dictionary of words. My solution consisted of using breadth first search to find a shortest path between two words. But apparently that wasn't good enough to get the job :( Would you guys know what I could have done wrong? Thank you so much. import collections import functools import re def time_func(func): import time def wrapper(*args, **kwargs): start = time.time() res = func(*args, **kwargs) timed = time.time() - start setattr(wrapper, 'time_taken', timed) return res functools.update_wrapper(wrapper, func) return wrapper class OneLetterGame: def __init__(self, dict_path): self.dict_path = dict_path self.words = set() def run(self, start_word, end_word): '''Runs the one letter game with the given start and end words.

• When should I use indexed arrays of OpenGL vertices?

  - by Tartley

  I'm trying to get a clear idea of when I should be using indexed arrays of OpenGL vertices, drawn with gl[Multi]DrawElements and the like, versus when I should simply use contiguous arrays of vertices, drawn with gl[Multi]DrawArrays. (Update: The consensus in the replies I got is that one should always be using indexed vertices.) I have gone back and forth on this issue several times, so I'm going to outline my current understanding, in the hopes someone can either tell me I'm now finally more or less correct, or else point out where my remaining misunderstandings are. Specifically, I have three conclusions, in bold. Please correct them if they are wrong. One simple case is if my geometry consists of meshes to form curved surfaces. In this case, the vertices in the middle of the mesh will have identical attributes (position, normal, color, texture coord, etc) for every triangle which uses the vertex. This leads me to conclude that: 1. For geometry with few seams, indexed arrays are a big win. Follow rule 1 always, except: For geometry that is very 'blocky', in which every edge represents a seam, the benefit of indexed arrays is less obvious. To take a simple cube as an example, although each vertex is used in three different faces, we can't share vertices between them, because for a single vertex, the surface normals (and possible other things, like color and texture co-ord) will differ on each face. Hence we need to explicitly introduce redundant vertex positions into our array, so that the same position can be used several times with different normals, etc. This means that indexed arrays are of less use. e.g. When rendering a single face of a cube: 0 1 o---o |\ | | \ | | \| o---o 3 2 (this can be considered in isolation, because the seams between this face and all adjacent faces mean than none of these vertices can be shared between faces) if rendering using GL_TRIANGLE_FAN (or _STRIP), then each face of the cube can be rendered thus: verts = [v0, v1, v2, v3] colors = [c0, c0, c0, c0] normal = [n0, n0, n0, n0] Adding indices does not allow us to simplify this. From this I conclude that: 2. When rendering geometry which is all seams or mostly seams, when using GL_TRIANGLE_STRIP or _FAN, then I should never use indexed arrays, and should instead always use gl[Multi]DrawArrays. (Update: Replies indicate that this conclusion is wrong. Even though indices don't allow us to reduce the size of the arrays here, they should still be used because of other performance benefits, as discussed in the comments) The only exception to rule 2 is: When using GL_TRIANGLES (instead of strips or fans), then half of the vertices can still be re-used twice, with identical normals and colors, etc, because each cube face is rendered as two separate triangles. Again, for the same single cube face: 0 1 o---o |\ | | \ | | \| o---o 3 2 Without indices, using GL_TRIANGLES, the arrays would be something like: verts = [v0, v1, v2, v2, v3, v0] normals = [n0, n0, n0, n0, n0, n0] colors = [c0, c0, c0, c0, c0, c0] Since a vertex and a normal are often 3 floats each, and a color is often 3 bytes, that gives, for each cube face, about: verts = 6 * 3 floats = 18 floats normals = 6 * 3 floats = 18 floats colors = 6 * 3 bytes = 18 bytes = 36 floats and 18 bytes per cube face. (I understand the number of bytes might change if different types are used, the exact figures are just for illustration.) With indices, we can simplify this a little, giving: verts = [v0, v1, v2, v3] (4 * 3 = 12 floats) normals = [n0, n0, n0, n0] (4 * 3 = 12 floats) colors = [c0, c0, c0, c0] (4 * 3 = 12 bytes) indices = [0, 1, 2, 2, 3, 0] (6 shorts) = 24 floats + 12 bytes, and maybe 6 shorts, per cube face. See how in the latter case, vertices 0 and 2 are used twice, but only represented once in each of the verts, normals and colors arrays. This sounds like a small win for using indices, even in the extreme case of every single geometry edge being a seam. This leads me to conclude that: 3. When using GL_TRIANGLES, one should always use indexed arrays, even for geometry which is all seams. Please correct my conclusions in bold if they are wrong.

• Managing BES Software Configurations

  - by DaveJohnston

  Hi, I am having problems with OTA deployment of a bespoke application that we have written. I have read loads of threads elsewhere and I have got mixed help, but for my particular case none of it has really helped. So I thought I would explain my exact situation and try and get some help here. I am running BES version 4.1.5 (Bundle 79) for Microsoft Exchange. The application we have written is split into 5 modules, which we control, and another 4 modules which are 3rd party libraries that we require. So for our modules the version numbers are regularly changing but for the others they are pretty much always going to remain the same. We have an alx file set up that identifies all of the files required and in fact I am able to create a software configuration and deploy the application with no problems. What I am trying to do however is maintain multiple versions of our application on the BES and be able to select which version I want to deploy to each user. I have tried this a number of ways (as I said I have read lots of other threads with solutions to this problem) but each seems to come with its own problem. First of all I tried just creating different configurations for each version of the application, but because they each had the same application ID the BES informed me that I couldn't do this. I read somewhere that the solution was to create a second shared folder (e.g. \Program Files\Common Files\RIM) and add the apploader stuff and the new version of the app to this folder. I could then create a second software configuration that would have the same application ID. The result of this seemed promising to start with. When I changed the config that was assigned to a user the new version was pushed out fine. But afterwards the BES reported that the device state was invalid, which meant I couldn't push anything else until I reactivated the device. I guess this is because the first config was never set to disallowed so the old version wasn't removed and the device essentially reported that it had multiple versions of the same application installed. The next suggestion I got was to change the application ID for each version, e.g. to include the version number. This meant that each version of the application could be included in a single configuration and I could set one to disallowed and the other to required. Initially this worked and the first version was deployed. But when I switched (i.e. the old version became disallowed and the new version required) the BES reported upgrade required and removed the old version. The device restarts and the old version is gone but the new version is not pushed out. I checked the BES and it still said Upgrade Required. I checked the log files and found: [40000] (11/12 09:50:27.397):{0xEB8} {[email protected], PIN=1234, UserId=2}SCS::PollDBQueueNewRequests - Queuing POLL_FOR_MISSING_APPS request [40000] (11/12 09:50:28.241):{0xE9C} RequestHandler::PollForMissingApps: Starting Poll For Missing Apps.

(You will notice I have removed actual names and email addresses etc for privacy reasons. But one question: where does the name of the module group come from? In my case it is close to the application ID but doesn't include the version number that I added at the end in order to get it to work. Is that information embedded in a COD file or something??) So it is reporting a duplicate module group on the device? What does this mean? I checked the device properties (as reported on the BES) and it confirms that the modules with the old version numbers are still present on the device. So the application has been removed but not the modules?? I checked the device and the modules are gone, so it is just the BES reporting that they are still there?? I checked the database and it has the modules in questions in the SyncDeviceMgmt table. If I delete these from the DB the BES changes to report Install Required, and low and behold the new version of the app is pushed out. So at the end of all that, my question is: does anyone have any other suggestions of how to handle upgrading our bespoke application OTA from the BES? Or can anyone point out something I am doing wrong in what I described above that might solve the problems I am having? I guess the question is why does the database maintain that the modules are on the device after they are removed? Thanks for any help you can provide.

• Spring Security and the Synchronizer Token J2EE pattern, problem when authentication fails.

  - by dfuse

  Hey, we are using Spring Security 2.0.4. We have a TransactionTokenBean which generates a unique token each POST, the bean is session scoped. The token is used for the duplicate form submission problem (and security). The TransactionTokenBean is called from a Servlet filter. Our problem is the following, after a session timeout occured, when you do a POST in the application Spring Security redirects to the logon page, saving the original request. After logging on again the TransactionTokenBean is created again, since it is session scoped, but then Spring forwards to the originally accessed url, also sending the token that was generated at that time. Since the TransactionTokenBean is created again, the tokens do not match and our filter throws an Exception. I don't quite know how to handle this elegantly, (or for that matter, I can't even fix it with a hack), any ideas? This is the code of the TransactionTokenBean: public class TransactionTokenBean implements Serializable { public static final int TOKEN_LENGTH = 8; private RandomizerBean randomizer; private transient Logger logger; private String expectedToken; public String getUniqueToken() { return expectedToken; } public void init() { resetUniqueToken(); } public final void verifyAndResetUniqueToken(String actualToken) { verifyUniqueToken(actualToken); resetUniqueToken(); } public void resetUniqueToken() { expectedToken = randomizer.getRandomString(TOKEN_LENGTH, RandomizerBean.ALPHANUMERICS); getLogger().debug("reset token to: " + expectedToken); } public void verifyUniqueToken(String actualToken) { if (getLogger().isDebugEnabled()) { getLogger().debug("verifying token. expected=" + expectedToken + ", actual=" + actualToken); } if (expectedToken == null || actualToken == null || !isValidToken(actualToken)) { throw new IllegalArgumentException("missing or invalid transaction token"); } if (!expectedToken.equals(actualToken)) { throw new InvalidTokenException(); } } private boolean isValidToken(String actualToken) { return StringUtils.isAlphanumeric(actualToken); } public void setRandomizer(RandomizerBean randomizer) { this.randomizer = randomizer; } private Logger getLogger() { if (logger == null) { logger = Logger.getLogger(TransactionTokenBean.class); } return logger; } } and this is the Servlet filter (ignore the Ajax stuff): public class SecurityFilter implements Filter { static final String AJAX_TOKEN_PARAM = "ATXTOKEN"; static final String TOKEN_PARAM = "TXTOKEN"; private WebApplicationContext webApplicationContext; private Logger logger = Logger.getLogger(SecurityFilter.class); public void init(FilterConfig config) { setWebApplicationContext(WebApplicationContextUtils.getWebApplicationContext(config.getServletContext())); } public void destroy() { } public void doFilter(ServletRequest req, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; if (isPostRequest(request)) { if (isAjaxRequest(request)) { log("verifying token for AJAX request " + request.getRequestURI()); getTransactionTokenBean(true).verifyUniqueToken(request.getParameter(AJAX_TOKEN_PARAM)); } else { log("verifying and resetting token for non-AJAX request " + request.getRequestURI()); getTransactionTokenBean(false).verifyAndResetUniqueToken(request.getParameter(TOKEN_PARAM)); } } chain.doFilter(request, response); } private void log(String line) { if (logger.isDebugEnabled()) { logger.debug(line); } } private boolean isPostRequest(HttpServletRequest request) { return "POST".equals(request.getMethod().toUpperCase()); } private boolean isAjaxRequest(HttpServletRequest request) { return request.getParameter("AJAXREQUEST") != null; } private TransactionTokenBean getTransactionTokenBean(boolean ajax) { return (TransactionTokenBean) webApplicationContext.getBean(ajax ? "ajaxTransactionTokenBean" : "transactionTokenBean"); } void setWebApplicationContext(WebApplicationContext context) { this.webApplicationContext = context; } }

• Can't access shared drive when connecting over VPN

  - by evolvd

  I can ping all network devices but it doesn't seem that DNS is resolving their hostnames. ipconfig/ all is showing that I am pointing to the correct dns server. I can "ping "dnsname"" and it will resolve but it wont resolve any other names. Split tunnel is set up so outside DNS is resolving fine So one issue might be DNS but I have the IP address of the server share so I figure I could just get to it that way. example: \10.0.0.1\ well I can't get to it that way either and I get "the specified network name is no longer available" I can ping it but I can't open the share.

• SQL Server 2008: Using Multiple dts Ranges to Build a Set of Dates

  - by raoulcousins

  I'm trying to build a query for a medical database that counts the number of patients that were on at least one medication from a class of medications (the medications listed below in the FAST_MEDS CTE) and had either: 1) A diagnosis of myopathy (the list of diagnoses in the FAST_DX CTE) 2) A CPK lab value above 1000 (the lab value in the FAST_LABS CTE) and this diagnosis or lab happened AFTER a patient was on a statin. The query I've included below does that under the assumption that once a patient is on a statin, they're on a statin forever. The first CTE collects the ids of patients that were on a statin along with the first date of their diagnosis, the second those with a diagnosis, and the third those with a high lab value. After this I count those that match the above criteria. What I would like to do is drop the assumption that once a patient is on a statin, they're on it for life. The table edw_dm.patient_medications has a column called start_dts and end_dts. This table has one row for each prescription written, with start_dts and end_dts denoting the start and end date of the prescription. End_dts could be null, which I'll take to assume that the patient is currently on this medication (it could be a missing record, but I can't do anything about this). If a patient is on two different statins, the start and ends dates can overlap, and there may be multiple records of the same medication for a patient, as in a record showing 3-11-2000 to 4-5-2003 and another for the same patient showing 5-6-2007 to 7-8-2009. I would like to use these two columns to build a query where I'm only counting the patients that had a lab value or diagnosis done during a time when they were already on a statin, or in the first n (say 3) months after they stopped taking a statin. I'm really not sure how to go about rewriting the first CTE to get this information and how to do the comparison after the CTEs are built. I know this is a vague question, but I'm really stumped. Any ideas? As always, thank you in advance. Here's the current query: WITH FAST_MEDS AS ( select distinct statins.mrd_pt_id, min(year(statins.order_dts)) as statin_yr from edw_dm.patient_medications as statins inner join mrd.medications as mrd on statins.mrd_med_id = mrd.mrd_med_id WHERE mrd.generic_nm in ( 'Lovastatin (9664708500)', 'lovastatin-niacin', 'Lovastatin/Niacin', 'Lovastatin', 'Simvastatin (9678583966)', 'ezetimibe-simvastatin', 'niacin-simvastatin', 'ezetimibe/Simvastatin', 'Niacin/Simvastatin', 'Simvastatin', 'Aspirin Buffered-Pravastatin', 'aspirin-pravastatin', 'Aspirin/Pravastatin', 'Pravastatin', 'amlodipine-atorvastatin', 'Amlodipine/atorvastatin', 'atorvastatin', 'fluvastatin', 'rosuvastatin' ) and YEAR(statins.order_dts) IS NOT NULL and statins.mrd_pt_id IS NOT NULL group by statins.mrd_pt_id ) select * into #meds from FAST_MEDS ; --return patients who had a diagnosis in the list and the year that --diagnosis was given with FAST_DX AS ( SELECT pd.mrd_pt_id, YEAR(pd.init_noted_dts) as init_yr FROM edw_dm.patient_diagnoses as pd inner join mrd.diagnoses as mrd on pd.mrd_dx_id = mrd.mrd_dx_id and mrd.icd9_cd in ('728.89','729.1','710.4','728.3','729.0','728.81','781.0','791.3') ) select * into #dx from FAST_DX; --return patients who had a high cpk value along with the year the cpk --value was taken with FAST_LABS AS ( SELECT pl.mrd_pt_id, YEAR(pl.order_dts) as lab_yr FROM edw_dm.patient_labs as pl inner join mrd.labs as mrd on pl.mrd_lab_id = mrd.mrd_lab_id and mrd.lab_nm = 'CK (CPK)' WHERE pl.lab_val between 1000 AND 999998 ) select * into #labs from FAST_LABS; -- count the number of patients who had a lab value or a medication -- value taken sometime AFTER their initial statin diagnosis select count(distinct p.mrd_pt_id) as ct from mrd.patient_demographics as p join #meds as m on p.mrd_pt_id = m.mrd_pt_id AND ( EXISTS ( SELECT 'A' FROM #labs l WHERE p.mrd_pt_id = l.mrd_pt_id and l.lab_yr >= m.statin_yr ) OR EXISTS( SELECT 'A' FROM #dx d WHERE p.mrd_pt_id = d.mrd_pt_id AND d.init_yr >= m.statin_yr ) )
