  • Admin now missing from Authors dropdown

    - by Driss Zouak
    I've been running my Wordpress install for months with 2 users, the original administrator which I use and another admin account created for my co-admin. We've been posting fine, no issues, all was great. Two days ago I created another user, and now whenever I log in as the original admin (my account) I am no longer in the authors dropdown list. Any new users I create show up, but my original account is no longer listed. I can't figure out what's going on, nor how to restore myself.

  • Does sending mails with mail() hide the recipieints address

    - by user161179
    I am trying to build a email messaging system for a classified site ( a la craigslist), so that users can email each other. emails of registered users are stored in a database. What I want is for the recipients email address to be hidden from the sender's . If I just use the mail() function and dynamically get the recipients email from the database, will this email be visible to the person sending the mail ?? if the recipients email is indeed hidden from the sender's when using mail() this way, then why does craigslist anonymize's email ? isn't it already anonymous ? Edit: so the email won't be visible to the person filling the form. SO the question remains is why does craigslist anonymizes email addresses? and whether I should implement the same ?

  • What is the best way to make a game timer in Actionscript 3?

    - by Nuthman
    I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?

  • How to delete unused sequences?

    - by user1023877
    We are using PostgreSQL. My requirement is to delete unused sequences from my database. For example, if I create any table through my application, one sequence will be created, but for deleting the table we are not deleting the sequence, too. If want to create the same table another sequence is being created. Example: table: file; automatically created sequence for id coumn: file_id_seq When I delete the table file and create it with same name again, a new sequence is being created (i.e. file_id_seq1). I have accumulated a huge number of unused sequences in my application database this way. How to delete these unused sequences?

  • How Android retrieves info of the Stacked Activities which are killed when memory goes low.

    - by taranfx
    I was reading on how Activities communicate and how the calls stack up on top of each other. But at any instant when the OS(or dalvik) is low on resources, it can choose to kill Paused or Stopped Activities. In this scenario, how do we restore previous state of the activity(in which it was before getting killed) when we reach the same activity on our way back. Does stack store the state as well as references to the Activity? Aren't their chances of achieving a different state when we re-constuct activity (onCreate)?

  • tortoisesvn - Error REPORT request failed on ../../../!svn/vcc/default

    - by John
    Users attempting to check out files from a particular Subversion 1.4.x repository with Apache 2.2 on Windows 2003 have suddenly begun getting an error message in their log windows upon checkout with TortoiseSVN 1.4: Error REPORT request failed on '/[path_to_repo]/!svn/vcc/default' Error REPORT of '/[path_to_repo]/!svn/vcc/default': 200 OK (http://[server_name]) This started following an hd crash on the server and subsequent restore of about 10 subversion repositories. Only one repository is having this problem after an attempted working directory reconciliation. The repo owner reconcile their working directory with the repository by modifying/deleting the hidden .svn directories (though this was not advised). I can't find anything on the Internets that represents my situation. The restored server is exactly as the original and no other repositories on this server are throwing errors. Any ideas on 1) what this error is and 2) how to fix it?

    - by Mike

Example is: i deploy a new installation of this framework to a new client, i want the following files to be downloaded (they have default values 'CHANGEME') and i just have to make changes specific to this client IE(database credentials, email address info, custom css styling). // the production config files i want the files but they need to be updated to specific client needs application/config/production/config.php application/config/production/database.php application/config/production/tank_auth.php // index page, defines the environment (production|development) /index.php // all of the css/js cache (keep the folder but not the contents) /assets/cache/* // production user based styling (color, fonts etc) needs to be updated specific to client needs /assets/frontend/css/user/frontend-user.css currently if i run git clone [email protected]:user123/myRepo.git httpdocs and then i edit the files above, all is great.. until i release a hotfix or patch and run git pull.

  • Cascading MVC controllers with CatchAll Routes

    - by Richard
    Hi, I have an MVC app which has its routes defined with the final route being a catch all route to a "PageController" for a database driven collection of pages. What I want to achieve is to be able to plugin to the app a second controller to the catch all route which the first controller passes on to if it does not find the url recieved in the database. Effectively I want to queue up controllers with catch all actions: public ActionResult PageCatchall(string url) { var page = repository.Get<Page>(string url); if (page != null) { // Handle the request return View(page) } // Otherwise pass to a new controller ???? } Anyone have any good ideas as to how to solve this? I have tried RedirectToAction but that requires that the next controller has a different route to the action. I have tried ActionInvoker but this failed to work the way I did it.

  • Is it possible to submit an update for an app on the AppStore without losing reviews?

    - by Frank Krueger
    Whenever I submit an update for me app, the number of reviews visible for it drops to 0. If the customer bothers to click through they can see the previous versions' reviews... But the damage has been done. Since the app has 0 stars, I see a significant drop in sales. It takes the app a good week of earning new reviews to restore sales. I usually version the app as 1.1, 1.2, 1.3 etc. Is there something I can do during the update process to prevent losing reviews like this?

  • A question about making a C# class persistant during a file load

    - by Adam
    Apologies for the indescriptive title, however it's the best I could think of for the moment. Basically, I've written a singleton class that loads files into a database. These files are typically large, and take hours to process. What I am looking for is to make a method where I can have this class running, and be able to call methods from within it, even if it's calling class is shut down. The singleton class is simple. It starts a thread that loads the file into the database, while having methods to report on the current status. In a nutshell it's al little like this: public sealed class BulkFileLoader { static BulkFileLoader instance = null; int currentCount = 0; BulkFileLoader() public static BulkFileLoader Instance { // Instanciate the instance class if necessary, and return it } public void Go() { // kick of 'ProcessFile' thread } public void GetCurrentCount() { return currentCount; } private void ProcessFile() { while (more rows in the import file) { // insert the row into the database currentCount++; } } } The idea is that you can get an instance of BulkFileLoader to execute, which will process a file to load, while at any time you can get realtime updates on the number of rows its done so far using the GetCurrentCount() method. This works fine, except the calling class needs to stay open the whole time for the processing to continue. As soon as I stop the calling class, the BulkFileLoader instance is removed, and it stops processing the file. What I am after is a solution where it will continue to run independently, regardless of what happens to the calling class. I then tried another approach. I created a simple console application that kicks off the BulkFileLoader, and then wrapped it around as a process. This fixes one problem, since now when I kick off the process, the file will continue to load even if I close the class that called the process. However, now the problem I have is that cannot get updates on the current count, since if I try and get the instance of BulkFileLoader (which, as mentioned before is a singleton), it creates a new instance, rather than returning the instance that is currently in the executing process. It would appear that singletons don't extend into the scope of other processes running on the machine. In the end, I want to be able to kick off the BulkFileLoader, and at any time be able to find out how many rows it's processed. However, that is even if I close the application I used to start it. Can anyone see a solution to my problem?

  • best way to create tables with ORM?

    - by ajsie
    assume that i start coding an application from scratch, is the best way to create tables when using an ORM (doctrine), to manually create tables in mysql and then generate models from the tables, or is it the other way around, that is to create the models in php and then generate tables from models? and if i already have a database, will the models created be optimal? cause i have heard some say that its best to create the database from scratch when using ORM, so that the relations are optimized for OOD. share your thoughts!

  • Rolling back a git tree, fully or partially (single file) how to?

    - by Tzury Bar Yochay
    On a given server, I have a set of daemons each of which has its own configuration file. I would like to use git to manage the configuration files editing during time and always have the option to rollback to the "factory defaults" in regards to all files or a specific one. For instance, given the following structure: $ ls -l total 0 -rw-r--r-- 1 tzury tzury 0 2011-01-05 06:36 bar.conf -rw-r--r-- 1 tzury tzury 0 2011-01-05 06:36 baz.conf -rw-r--r-- 1 tzury tzury 0 2011-01-05 06:36 foo.conf Assuming all those .conf files are stored in a git repository, I want to be able to restore all files into their original shape (that would be the first git commit). Yet, I would also like to be able to rollback a specific file to the factory defaults, while others remain up to date.

  • How to use GPS data like the double value returned by getLatitude()?

    - by Dan
    I have been searching quite a bit for an answer, but maybe I'm just not using the correct terminology. I am creating an app that will access a database to return a list of other users that are within a certain distance of the users location. I've never worked with this type of data, and I don't really know what the values mean. I'd like to do all the calculations on the backend with either MySQL or PHP. Currently, I am storing the latitude and longitude as doubles within the database. I can access them and store them, but I have no idea how I might be able to sort them based on distance. Perhaps I should be using a different type or some technique that is common in this area. TIA.

  • How do I split the output from mysqldump into smaller files?

    - by lindelof
    I need to move entire tables from one MySQL database to another. I don't have full access to the second one, only phpMyAdmin access. I can only upload (compressed) sql files smaller than 2MB. But the compressed output from a mysqldump of the first database's tables is larger than 10MB. Is there a way to split the output from mysqldump into smaller files? I cannot use split(1) since I cannot cat(1) the files back on the remote server. Or is there another solution I have missed? Edit The --extended-insert=FALSE option to mysqldump suggested by the first poster yields a .sql file that can then be split into importable files, provided that split(1) is called with a suitable --lines option. By trial and error I found that bzip2 compresses the .sql files by a factor of 20, so I needed to figure out how many lines of sql code correspond roughly to 40MB.

  • SQL version control methodology

    - by Tom H.
    There are several questions on SO about version control for SQL and lots of resources on the web, but I can't find something that quite covers what I'm trying to do. First off, I'm talking about a methodology here. I'm familiar with the various source control applications out there and I'm familiar with tools like Red Gate's SQL Compare, etc. and I know how to write an application to check things in and out of my source control system automatically. If there is a tool which would be particularly helpful in providing a whole new methodology or which have a useful and uncommon functionality then great, but for the tasks mentioned above I'm already set. The requirements that I'm trying to meet are: The database schema and look-up table data are versioned DML scripts for data fixes to larger tables are versioned A server can be promoted from version N to version N + X where X may not always be 1 Code isn't duplicated within the version control system - for example, if I add a column to a table I don't want to have to make sure that the change is in both a create script and an alter script The system needs to support multiple clients who are at various versions for the application (trying to get them all up to within 1 or 2 releases, but not there yet) Some organizations keep incremental change scripts in their version control and to get from version N to N + 3 you would have to run scripts for N-N+1 then N+1-N+2 then N+2-N+3. Some of these scripts can be repetitive (for example, a column is added but then later it is altered to change the data type). We're trying to avoid that repetitiveness since some of the client DBs can be very large, so these changes might take longer than necessary. Some organizations will simply keep a full database build script at each version level then use a tool like SQL Compare to bring a database up to one of those versions. The problem here is that intermixing DML scripts can be a problem. Imagine a scenario where I add a column, use a DML script to fill said column, then in a later version that column name is changed. Perhaps there is some hybrid solution? Maybe I'm just asking for too much? Any ideas or suggestions would be greatly appreciated though. If the moderators think that this would be more appropriate as a community wiki, please let me know. Thanks!

  • How to deploy updates to .NET website in cluster

    - by royappa
    We are operating a corporate web application on a load-balanced cluster that consists of two identical IIS servers talking to a single MSSQL database. To deploy updates I am using this primitive process: 1) Make a copy of the entire site folder (wwwroot\inetpub\whatever) on each IIS box 2) Download the updated, compiled files onto each IIS box from our development area 3) Shut down IIS both web servers 4) Copy the new and updated files into the wwwroot folder (overwriting any same files) 5) Then restart IIS on both machines When there are database changes involved there are a few other steps. The whole process is fairly quick but it is ugly and fraught with danger, so it has to be done with full concentration. I would like to just push one button to make it all happen. And I want a one-click rollback in case there is a problem (that's the reason I make the copy in step #1). I am looking for tools to manage and improve this process. If it also helped us maintain a changelog, that would be nice. Thanks.

  • Embedded Java Databases for Large Data Sets

    - by ExAmerican
    I would like to port a PHP/MySQL-based client/server application to be a standalone desktop application written in Java. The database has grown to be fairly large, with several tables with hundreds of thousands of rows. I expect these could grow to over a million entries for certain tables. What embedded database would best handle this? HSQLDB and Sqlite seem to be the obvious choices, though I'm guessing there are others out there as well. My main priorities are the ability to perform queries on large amounts of data efficiently (this thread seems to confirm Sqlite can handle this) and the ease with which I can import old data from MySQL (I remember HSQLDB being kind of a pain for that). Note: I am aware that similar questions comparing embedded databases have been posted before (for example here and here) but as my priorities differ somewhat from most applications considering the large data migration I thought it justified a new question.
