  • How should I deal with sqlite errors?

    - by Dustin
    I have a long running application written in a mix of C and C++ that stores data in sqlite. While I am confident that committed data will remain available (barring mechanical failure) and uncommitted data will not be, it's not clear to me what I can do with this sort of middle state. I do a large number of inserts in a transaction and then commit it. When an error occurs on a given statement, I can schedule it to be attempted at some point in the future. It sounds like some errors might implicitly rollback my transaction (which would be undesirable if true). A larger problem is what happens when my commit itself fails. Currently, I'm just going to continue to retry it until it works. I would expect that whatever would cause my commit to fail may very well also cause a rollback to fail. What is the recommended mechanism for error handling in such a situation?

  • Adding variably named fields to Python classes

    - by Carson Myers
    I have a python class, and I need to add an arbitrary number of arbitrarily long lists to it. The names of the lists I need to add are also arbitrary. For example, in PHP, I would do this: class MyClass { } $c = new MyClass(); $n = "hello" $c.$n = array(1, 2, 3); How do I do this in Python? I'm also wondering if this is a reasonable thing to do. The alternative would be to create a dict of lists in the class, but since the number and size of the lists is arbitrary, I was worried there might be a performance hit from this. If you are wondering what I'm trying to accomplish, I'm writing a super-lightweight script interpreter. The interpreter walks through a human-written list and creates some kind of byte-code. The byte-code of each function will be stored as a list named after the function in an "app" class. I'm curious to hear any other suggestions on how to do this as well.

  • Operator overloading in generic struct: can I create overloads for specific kinds(?) of generic?

    - by Carson Myers
    I'm defining physical units in C#, using generic structs, and it was going okay until I got the error: One of the parameters of a binary operator must be the containing type when trying to overload the mathematical operators so that they convert between different units. So, I have something like this: public interface ScalarUnit { } public class Duration : ScalarUnit { } public struct Scalar<T> where T : ScalarUnit { public readonly double Value; public Scalar(double Value) { this.Value = Value; } public static implicit operator double(Scalar<T> Value) { return Value.Value; } } public interface VectorUnit { } public class Displacement : VectorUnit { } public class Velocity : VectorUnit { } public struct Vector<T> where T : VectorUnit { #... public static Vector<Velocity> operator /(Vector<Displacement> v1, Scalar<Duration> v2) { return new Vector<Velocity>(v1.Magnitude / v2, v1.Direction); } } There aren't any errors for the + and - operators, where I'm just working on a Vector<T>, but when I substitute a unit for T, suddenly it doesn't like it. Is there a way to make this work? I figured it would work, since Displacement implements the VectorUnit interface, and I have where T : VectorUnit in the struct header. Am I at least on the right track here? I'm new to C# so I have difficulty understanding what's going on sometimes.

  • Best way to notify several java applets/applications of a change on a server

    - by Dustin
    I need to know the best (fastest) way to have a server (preferably a php based one, but a jsp/servlet one could be set up as well using google app engine) notify several java applets/applications that a change has occurred to the data. The way i am picturing this to work will be very similar to that of the way i think an online java game (like Runescape) works User 1: Changes data on server. Server: returns success to User 1, notifies connected computers of change. Connected Computer 1: processes change, returns success to server. Connected Computer 2: processes change, returns success to server. Connected Computer 3: processes change, returns success to server. Connected Computer 4: processes change, returns success to server. I am hoping to have this entire process complete in half a second, and not involve polling as there will be long durations of nothing, followed by a sudden moment where 4 events happen in succession.

  • MySQL look for missing ratings

    - by Dustin
    Hopefully I can ask this without being confusing. I am a photographer and I am having some of our clients rate pictures that we have taken. We have hundreds of pictures in our portfolio that they may be rating. What I want to do is ask our clients to rate pictures again, but only show them the pictures they haven't yet rated. I currently have three tables: one that stores the actual ratings, one that stores the pictures (or location of each picture), and one that stores the information about the rater. I'm using codeigniter for my db management, if that helps at all. What I have so far is this: "SELECT * FROM ratings LEFT JOIN portfolio ON ratings.portfolioid = portfolio.portfolioid" This will give me a row for each rating, but won't show me where a rating is missing for a picture. Thanks in advance!

  • Decorator Design Pattern Use With Service Objects (wSingleton)

    - by Dustin
    I'm working on a project where I need to add some functionality to a service object and using a decorator to add it in seems like a good fit. However, I've only ever used decorators with simple beans, never on a singleton like a service object. Has anyone ever done this before and what are the pros and cons? In this case I don't think creating a subclass will work so a decorator seems to be a good fit. What are your thoughts on doing this?

  • Extract elements from list based on object property type

    - by Dustin Digmann
    Often, I have a list of objects. Each object has properties. I want to extract a subset of the list where a specific property has a predefined value. Example: I have a list of User objects. A User has a homeTown. I want to extract all users from my list with "Springfield" as their homeTown. I normally see this accomplished as follows: List users = getTheUsers(); List returnList = new ArrayList(); for (User user: users) { if ("springfield".equalsIgnoreCase(user.getHomeTown()) returnList.add(user); } I am not particularly satisfied with this solution. Yes, it works, but it seems so slow. There must be a non-linear solution. Suggestions?

  • Retreive value stored in array with jquery index

    - by Dustin
    I am trying to retreive the stored value (div id) of an index stored in var "current" when it's div is clicked, so I can use it in a function to iterate through to the next index later. I want to store this stored value in a var so I can use it in a div show/hide function. my html is quite simple: <div class="gallerypreview" id="1"></div> <div class="gallerypreview" id="2"></div> <div class="gallerypreview" id="3"></div> my javascript is something like this: var images = new Array(); $(document).ready( function(){ $('.gallerypreview').each(function() { images.push($(this).attr("id")); }); $('.gallerypreview').click(function() { var current = $('.gallerypreview').index(this); }); }); how would I go about retrieving the div id from this clicked div? nothing I have tried has worked. I can get the index # fine, but I cannot find the value of the index using any functions that utilize the index # yet.

  • Jquery gradient behavior applies to all but first URL

    - by Dustin
    I've got a page that shows my photography portfolio. I'm trying to do a jquery gradient on the text, and it's working on all but the first link. Here's the html: <h1><a href="portfolio/engagements"><span></span>engagements</a> | </h1><br> <h1><a href="portfolio/weddings"><span></span>weddings</a> | </h1> <br> <h1><a href="portfolio/bridals"><span></span>bridals</a> | </h1> <br> <h1><a href="portfolio/families"><span></span>families</a> | </h1> <br> <h1><a href="portfolio/seniors"><span></span>seniors</a> </h1> <br> And here's the jquery call: $(".jquery h1").prepend("<span></span>"); And here's the css for it: .gradient4 span { background: url(images/gradient-dark.png) repeat-x; position: absolute; bottom: -0.1em; display: inline; width: 100%; height: 29px; } The problem I'm having is that all urls but the first link (currently 'engagements'), have the gradient effect. Any ideas why the first link isn't working?

  • Make graphics on left and right side of text change width depending on the amount of text?

    - by Dustin McGrew
    I need to have an H1 tag centered between two graphics on the left and right of the text. The H1 text will be various widths depending on what page you are on. The dot on the left should stay on the left edge of the site and the line should extend until it reaches the edge of the text. Same for the right side. Is there a way to accomplish this by using CSS or even some jquery/javascript? In the attached graphic, if the text was just "WHO YOU ARE" I'd need the bars on the left and right to grow wider to bump up against the edges of the text.

  • Upgrade issues due to broken "dependency problems prevent configuration of linux-image-generic" error

    - by tsukune1791
    okay, I've recently upgrade from 11.10 to 12.04 and I've been having some issues. I don't know if its a bug or not, but I thought I would submit it here. Okay here's a little background; I ran the distro update from the update manager and got a couple errors that I didn't catch. the computer restarted, and when I logged the Launcher and my top bar of the Ubuntu desktop didn't load. While it was trying to load a couple error messages came up, I think they were called "apport", saying they couldn't send the bug information for some reason. I believe it said somethings wrong with my internet connection, but nothing's wrong with it. Anyway I tried running some things in terminal, namely sudo apt-get -f install sudo apt-get upgrade sudo apt-get dist-upgrade and keep getting the following errors; dustin@marceau-laptop:~$ sudo apt-get dist-upgrade [sudo] password for dustin: Reading package lists...

  • Can find any /.ecryptfs dir to retrieve my encrypted home dir

    - by Roberto de Armas
    At firs sorry for my english, it isn't my native languaje. I've readed some questions similar but no the exactly whith the same problem. I've moved my home directory to a separated partitión (Ubuntu 11.10) following this tutorial http://www.ubuntu-es.org/node/58233 After checking that they were all my files and folders (forgetting that one of dirs was encrypted by ecryptfs) i've installed fedora 16. Well, suprised when in my home folder was an Readme.txt advising me that my folder was unmounted for security reasons and proposing to type in comand line "ecryptfs-mount-Private" (din't work) or make click on labeled icon "acces your private data desktop" (neither din't work). After three days reading all i could find on the internet, i follow The Dustin Kirkland tutorial in http://blog.dustinkirkland.com/2011/04/introducing-ecryptfs-recover-private.html, but any /.ecryptfs was found. I'm sure that the data are somewere (the size of the moved dir is identical to the original one). Any help would by greatly appreciated. Thaks a lot.

  • How can I remove packages using preseed?

    I'm setting up an automated "no questions asked" preseed system and using Dustin Kirkland's server preseed as an example. He uses the following line to install three packages as part of the automated install: d-i pkgsel/include string byobu vim openssh-server I am looking for the inverse of this, basically be able to remove packages as part of the automated install. I've checked the Installation Guide I've checked this example preseed, but it's not clear if this is the canonical list of every single option available. I am thinking I need to to use d-i preseed/late_command string apt-remove packagename to clean up stuff I don't want when the install is done, but I am not sure

  • transparent home directory encryption

Problem or query is my home directory is encrypted & has a www folder ... now when I reboot the system the decryption doesnt happen at startup/boot & apache is not able to find the files rather the folder www since it is not mounted ... in order to mount it I have to login .... is there a way by which an encrypted home / private folder can be mounted at boot without human intervention ? #2 I have installed ubuntu server 11.10 & had selected "encrypt home directory" when installing the same. With ubuntu things are working transparently even after reboot & without logging in. Kindly can anyone pls explain or guide on the same ?

  • SQLRally Nordic gets underway

    - by Rob Farley
    PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

  • Sonicwall VPN, Domain Controller Issues

    - by durilai
    I am trying to get the domain logon script to execute when I connect to VPN. I have a SonicWall 4060PRO, with the SonicOS Enhanced 4.2.0.0-10e. The VPN connects successfully, but the script does not execute. I am posting the log below, but I see two issues. The first is the inability to connect to domain. 2009/12/18 19:49:53:457 Information XXX.XXX.XXX.XXX NetGetDCName failed: Could not find domain controller for this domain. The second is the failure of the script. 2009/12/18 19:49:53:466 Warning XXX.XXX.XXX.XXX Failed to execute script file \DT-WIN7netlogondomain.bat, Last Error: The network name cannot be found.. I assume the second issue is caused because of the first, also on the second issue it seems to be trying to get the logon script from my local PC, not the server. Finally, the DC can be pinged and reached by its computer name once the VPN is connected. The shares that the script is tring to map can be mapped manually. Any help is appreciated. 2009/12/18 19:49:31:063 Information The connection "GroupVPN_0006B1030980" has been enabled. 2009/12/18 19:49:32:223 Information XXX.XXX.XXX.XXX Starting ISAKMP phase 1 negotiation. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX Starting aggressive mode phase 1 exchange. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX NAT Detected: Local host is behind a NAT device. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX The SA lifetime for phase 1 is 28800 seconds. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX Phase 1 has completed. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX Received XAuth request. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX XAuth has requested a username but one has not yet been specified. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX Sending phase 1 delete. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX User authentication information is needed to complete the connection. 2009/12/18 19:49:32:393 Information An incoming ISAKMP packet from XXX.XXX.XXX.XXX was ignored. 2009/12/18 19:49:36:962 Information XXX.XXX.XXX.XXX Starting ISAKMP phase 1 negotiation. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX Starting aggressive mode phase 1 exchange. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX NAT Detected: Local host is behind a NAT device. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX The SA lifetime for phase 1 is 28800 seconds. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX Phase 1 has completed. 2009/12/18 19:49:37:094 Information XXX.XXX.XXX.XXX Received XAuth request. 2009/12/18 19:49:37:100 Information XXX.XXX.XXX.XXX Sending XAuth reply. 2009/12/18 19:49:37:110 Information XXX.XXX.XXX.XXX Received initial contact notify. 2009/12/18 19:49:37:153 Information XXX.XXX.XXX.XXX Received XAuth status. 2009/12/18 19:49:37:154 Information XXX.XXX.XXX.XXX Sending XAuth acknowledgement. 2009/12/18 19:49:37:154 Information XXX.XXX.XXX.XXX User authentication has succeeded. 2009/12/18 19:49:37:247 Information XXX.XXX.XXX.XXX Received request for policy version. 2009/12/18 19:49:37:253 Information XXX.XXX.XXX.XXX Sending policy version reply. 2009/12/18 19:49:37:303 Information XXX.XXX.XXX.XXX Received policy change is not required. 2009/12/18 19:49:37:303 Information XXX.XXX.XXX.XXX Sending policy acknowledgement. 2009/12/18 19:49:37:303 Information XXX.XXX.XXX.XXX The configuration for the connection is up to date. 2009/12/18 19:49:37:377 Information XXX.XXX.XXX.XXX Starting ISAKMP phase 2 negotiation with 10.10.10.0/255.255.255.0:BOOTPC:BOOTPS:UDP. 2009/12/18 19:49:37:377 Information XXX.XXX.XXX.XXX Starting quick mode phase 2 exchange. 2009/12/18 19:49:37:472 Information XXX.XXX.XXX.XXX The SA lifetime for phase 2 is 28800 seconds. 2009/12/18 19:49:37:472 Information XXX.XXX.XXX.XXX Phase 2 with 10.10.10.0/255.255.255.0:BOOTPC:BOOTPS:UDP has completed. 2009/12/18 19:49:37:896 Information Renewing IP address for the virtual interface (00-60-73-4C-3F-45). 2009/12/18 19:49:40:189 Information The virtual interface has been added to the system with IP address 10.10.10.112. 2009/12/18 19:49:40:319 Information The system ARP cache has been flushed. 2009/12/18 19:49:40:576 Information XXX.XXX.XXX.XXX NetWkstaUserGetInfo returned: user: Dustin, logon domain: DT-WIN7, logon server: DT-WIN7 2009/12/18 19:49:53:457 Information XXX.XXX.XXX.XXX NetGetDCName failed: Could not find domain controller for this domain. 2009/12/18 19:49:53:457 Information XXX.XXX.XXX.XXX calling NetUserGetInfo: Server: , User: Dustin, level: 3 2009/12/18 19:49:53:460 Information XXX.XXX.XXX.XXX NetUserGetInfo returned: home dir: , remote dir: , logon script: 2009/12/18 19:49:53:466 Warning XXX.XXX.XXX.XXX Failed to execute script file \DT-WIN7netlogondomain.bat, Last Error: The network name cannot be found..

  • Throwing Exception in CTOR and Smart Pointers

    - by David Relihan
    Is it OK to have the following code in my constructor to load an XML document into a member variable - throwing to caller if there are any problems: MSXML2::IXMLDOMDocumentPtr m_docPtr; //member Configuration() { try { HRESULT hr = m_docPtr.CreateInstance(__uuidof(MSXML2::DOMDocument40)); if ( SUCCEEDED(hr)) { m_docPtr->loadXML(CreateXML()); } else { //throw exception to caller } } catch(...) { //throw exception to caller } } Based on Scott Myers RAII implementations in More Effective C++ I believe I am alright in just allowing exceptions to be thrown from CTOR as I am using a smart pointer(IXMLDOMDocumentPtr). Let me know what you think....
