• remove a varchar2 string from the middle of table data values

  - by Michelle Daniel

  Data in the file_name field of the generation table should be an assigned number, then _01, _02, or _03, etc. and then .ldf (example 82617_01.pdf). Somewhere, the program is putting a state name and sometimes a date/time stamp, between the assigned number and the 01, 02, etc. (82617_ALABAMA_01.pdf or 19998_MAINE_07-31-2010_11-05-59_AM.pdf or 5485325_OREGON_01.pdf for example). We would like to develop an SQL statement to find the bad file names and fix them. In theory it seems rather simple to find file_names that include a varchar2 data type and remove it, but putting the statement together is beyond me. Any help or suggestions apprecuiated. Something like ........... UPDATE GENERATION SET FILE_NAME (?) WHERE FILE_NAME (?...LIKE '%STRING%');?

• Is there any reason why someone would want to create an Core Data model programmatically?

  - by mystify

  I wonder in which cases it would be good to make an NSManagedObjectModel completely programmatically, with NSEntityDescription instances and all this stuff. I'm that kind of person who prefers to code programmatically, rejecting Interface Builder. But when it comes to Core Data, I have a hard time figuring out why I should kill my time NOT using the nice Xcode Data Modeler tool. And since data models are stuck to a given state (except when you want to do some ugly migration operations where thinks probably go wrong and users get mad, really mad), I see no big sense in a data model that's made programmatically for the purpose of changing it all the time. Did I miss something?

• Twitter and Facebook on iPhone - save sessions across app launches?

  - by lostInTransit

  Hi I am using OAuth for twitter and fb-connect for facebook authentication in my iPhone app. Is it possible to save the user sessions across app launches? i.e. if the user logs in once, the next time they launch the app, we log them in automatically from some state saved the last time the app closed? For Twitter would it work if I just save the auth_token and use it every time the user wants to use twitter from my app? Or do I need to do anything else? I could not get it to work like that so wondering if I was doing something wrong. Thanks.

• Proper way to structure a Sync Framework DAL

  - by Refracted Paladin

  I am creating a WPF app that needs to allow users to work in a temporary disconnected state and I plan to use a Local Database Cache. My question's are about my data access layer. Do you typically create the whole DAL to point at the Cache or both and create a switching mechanism? Is Entity's a good way to go for my DAL against the Cache? I am used to L2S but my understanding is that I can't use that against SQLCE, correct? Thanks! PS: Any good resources out there for using Sync, Linq, and WPF ALL TOGETHER? Tutorials, videos, etc?

• What wiki tools exist to generate shippable user doc from a wiki?

  - by tletnes

  I am looking into using a wiki (prefer mediawiki, but not a req.) as the repository for developer generated documentation (User Guides, Release Notes, Application Notes, Errata, etc.) from a collaborative/easy-to-update point of view a wiki seems like a good match, however since this documentation will ultimately ship to customers we want to be able to export the documents in their final state (e.g. during the release cycle) to static versions that no longer include histories. Ideally the export would leave the document n a form where errors could be easily fixed by a non-programmer It would be good if niceties like section ordering and table of contents were available, or easy to add after the fact. Are any tools with features like these avalible?

I want the columns to be side by side not in one column

• How to rebase one Git repository onto another one?

  - by kroimon

  Hi there! I had one Git repository (A) which contains the development of a project until a certain point. Then I lost the USB stick this repo A was on. Luckily I had a backup of the latest commit, so I could create a new repository (B) later where I imported the latest project's state and continue development. Now I recovered that lost USB stick, so I have two Git repositories. I think I just have to rebase repo B onto repo A somehow, but I have no idea how to do that, maybe using fetch/pull and rebase? Thanks in advance for your help!

• Is my TFS2010 backup/restore hosed?

  - by bwerks

  Hi all, I recently set up a sandbox TFS to test TFS-specific features without interfering with the production TFS. I was happy I did this sooner than I thought--I hadn't been backing up the encryption key from SSRS and upon restoring the reporting databases, they remained inactive, requiring initialization that could only come from applying the encryption key. Said encryption key was lost when I nuked the partition after backing up the TFS databases. The only option I seemed to have is to delete the encrypted data. I'm fine with this, since there wasn't much in there to begin with, however once they're deleted I'm not quite sure how to configure TFS to recognize a new installation of these services while using the restored versions of everything else. Unfortunately, the TFS help file doesn't seem to account for this state though. Is there a way to essentially rebuild the reporting and analysis databases? Or are they gone forever?

• XNA how to organize code with game components (managers)

  - by Johannes

  XNA If I have a button class, and I have a buttonManager class that manages what buttons to be drawn to the screen depending on what the current game state is (main menu, in game, etc), how do I organize my code so that when I click on a button, it takes the user to a different screen. (ex. options menu, ingame). To be more specific, if I were to put the check to see if the user clicks on the button within the buttonManager how would I have the game switch and run the actual game (which is in an entire different class)? Main gameclass buttonManager game component (adds buttons) Button class

• Can Tomcat provide seperate (or HTTPS only) sessions for HTTPS requests?

  - by Joe

  I have a web application which contains both secure (SSL) and non-secure pages. A user can login to the site and must appear logged-in in both the SSL and non-SSL areas. (NB. SSL isn't implemented via Tomcat, but via Apache HTTPD servers which sit in front of Tomcat - so Tomcat has no SSL configuration.) The logged-in state is currently maintained via a servlet session (using Tomcat's vanilla session management). The obvious issue with this approach is that the JSESSIONID cookie is transported over both HTTP and HTTPS connections, meaning that it's potentially possible to intercept it and hijack the session. Are there any solutions to this without rolling our own session management (i.e. does Tomcat cater for this situation)? I'm prepared to implement our own session management, but don't want to reinvent something that may already be supported.

• Is it ok to Swallow SocketExceptions in some situations?

  - by NoPyGod

  Let's say I've programmed an application which connects to a server using the Socket Class (TCP). If I encounter a SocketException while reading or writing, then obviously I have to do go ahead and run a disconnection routine to change the application's state to Disconnected. But what if I've started to Disconnect, and while I'm cleaning up, a SocketException occurs? The SocketException doesn't really mean anything to me, as I was going to shutdown the socket myself anyway.. so is it ok to swallow it? I really want to know what the best practice for this situation is.

• embed multiple youtube videos to chromeless player cue

  - by Quaze

  So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

• Retrive multiple values from single dimension value / key JSON

  I'm busting my head trying to work this out. "ContentBlock1":["2","22"] I have been trying to get the 2 and the 22 into a comma sepertaed string so i can use it within a MySQL IN(2,22) query. I currently have tried several ways but none seem to work for me. $ContentBlock = my json data; $cid = json_decode($ContentBlock,true); foreach ($cid as $key){ $jsoncid = "$key ,"; } And then: SELECT * FROM content WHERE featured=1 AND state=1 AND catid IN($jsoncid) ORDER BY ordering ASC LIMIT 4");

• Rollback to a specific moment with PostgreSQL

  - by mada54

  Hi, Is there a way to rollback to a specific starting point. Im looking for something like this. Start specific_point; Now after this, an other application connected with the SAME login will insert & delete datas (webservices with crud operations) for about 2 minutes doing tests. Each webservice call is declared as a transaction with Spring Ws. After that i want to rollback to the specific_point to have a clean database to a known previous state. I was thinking that ROLLBACK TO SAVEPOINT foo; was the solution but not unfortunately? Any idea ? Configuration: PostgreSQL 8.4 / windows XP Regards

• Polymorphic classes in templates

  - by soxarered

  Let's say we have a class hierarchy where we have a generic Animal class, which has several classes directly inherit from it (such as Dog, Cat, Horse, etc..). When using templates on this inheritance hierarchy, is it legal to just use SomeTemplateClass<Animal> and then shove in Dogs and Cats and Horses into this templated object? For example, assume we have a templated Stack class, where we want to host all sorts of animals. Can I simply state Stack<Animal> s; Dog d; s.push(d); Cat c; s.push(c);

• I get "stack level too deep" error when using a named scope

  - by Brian Roisentul

  I'm using ruby on rails 2.3.8 and when I write the syntax shown below I get the "stack level too deep" error message. The model is called Announcement and the line of the error looks like this: Tag.find(category_id).announcements.published Where published is named_scope :published, :conditions => "announcements.state = 'published'" I use this named scope in many other places and it works fine. What am I doing wrong? (the relationship between Tag and Announcement model is ok because if I remove the ".published" method from that line it works just fine).

• LINQ to SQl updating primary key field?

  - by Curtis White

  I have a linq to sql table/class that uses a GUID as both a primary key and as foreign key. This problem came up when factoring some code that previously worked. The exception generated is "Operation is not valid due to the current state of the object." The process I use is as such: aspnet_User user() = new aspnet_User(); aspnet_user.childTable = new childTable(); .. set some properties user.Insert() -> my custom method ... @ my custom method using (mycontext dc = new context() ) { user.childTable.ID = (Guid)myNewlyCreatedGuid; } The exception occurs on the assignment childTable.set_UserId().

• Easy way to replicate web page across machines?

  - by Mike_G

  I am trying to replicate a browser page to another browser on another machine. I basically want to reproduce a page exactly how it appears to a customer for viewing by the website owner. I have done this before using some impersonation trickery, but found that it would throw the session state out of wack when the site owner would switch customers. So I would like to stay away from cookie and authentication manipulation. Anybody done anything like that? Is there a way to easily transfer the DOM to a webservice? The tech/programming at my disposal are C#, javascript, WCF.

• Fault address when malloc/free pthread_t across threads

  - by scleung

  Fault address occurred when i malloc pthread_t to save a newly created thread id and free it in another thread. Codes as follows: typedef struct _TaskInfo { // int dummy_int; pthread_t tid; } TaskInfo; void* dummy_task(void* pArg) { free(pArg); return NULL; } void create_task() { TaskInfo *pInfo; pthread_attr_t attr; // set detached state stuff ... pInfo = (TaskInfo*) malloc(sizeof(TaskInfo)); pthread_create(&pInfo->tid, &attr, dummy_task, pInfo); // destroy pthread attribute stuff ... } int main() { int i; while(i < 10000) { create_task(); ++i; } return 0; } When I uncomment the member dummy_int of TaskInfo it sometimes ran successfully, but sometimes failed. My platform is VMWare + Ubuntu 9.10 + ndk r3 Thanks!

• jquery animating different img widths

  - by romeozor

  Hi there, I've been searching for an answer for a long time with no avail, so it's time to ask. I'm trying to use .animate() to change the size of an image once clicked. The first state of the image would be a thumbnail size, which would animate to the image's original size, then to a thumbnail again. The problem is, not all the images have the same "original" size so I need a way to tell one generic function to switch to the current image's original size. This is my current code which loads on $(window).load: $('img[class=resize]').click(function (){ if ($(this).width() != 150) { $(this).animate({width: '150px'}, 400); } else { $(this).animate({width: ''}, 400); } }); Now this obviously doesn't work the way I want it, because .animate() thinks when I say width: '' I want to make the width = 0. Any suggestions how I should go about this?

• What are the advantages of a rebase over a merge in git?

  - by eSKay

  In this article, the author explains rebasing with this diagram: Rebase: If you have not yet published your branch, or have clearly communicated that others should not base their work on it, you have an alternative. You can rebase your branch, where instead of merging, your commit is replaced by another commit with a different parent, and your branch is moved there. while a normal merge would have looked like this: So, if you rebase, you are just losing a history state (which would be garbage collected sometime in the future). So, why would someone want to do a rebase at all? What am I missing here?

• Removing Duplicates in an array in C

  - by LuckySlevin

  The question is a little complex. The problem here is to get rid of duplicates and save the unique elements of array into another array with their original sequence. For example : If the input is entered b a c a d t The result should be : b a c d t in the exact state that the input entered. So, for sorting the array then checking couldn't work since I lost the original sequence. I was advised to use array of indices but I don't know how to do. So what is your advise to do that?

• Git - will the file moves be detected?

  - by Ben Aston

  I performed some modifications on a branch (A). I then decided to create a brand new branch (B) based on the state of my existing working copy and commit and push to that. There were a number of files that had been moved during my earlier refactoring, and hence were now not included in version control having been moved directly in the filesystem. By accident I did not add these files to git before committing and pushing to the new branch (B). If I now add these files and commit and push, will Git be able to detect the file move operations?

• why Observable snapshot observer vector

  - by han14466

  In Observable's notifyObservers method, why does the coder use arrLocal = obs.toArray();? Why does not coder iterate vector directly? Thanks public void notifyObservers(Object arg) { Object[] arrLocal; synchronized (this) { /* We don't want the Observer doing callbacks into * arbitrary code while holding its own Monitor. * The code where we extract each Observable from * the Vector and store the state of the Observer * needs synchronization, but notifying observers * does not (should not). The worst result of any * potential race-condition here is that: * 1) a newly-added Observer will miss a * notification in progress * 2) a recently unregistered Observer will be * wrongly notified when it doesn't care */ if (!changed) return; arrLocal = obs.toArray(); clearChanged(); } for (int i = arrLocal.length-1; i>=0; i--) ((Observer)arrLocal[i]).update(this, arg); }
