  • Maintaining a secure database of user logins and info?

    - by Rafe Kettler
    I want to have a login form on a charity website I am building (it's for a friend, and I'm learning on the go), and I want to know what languages/software should I learn to build databases for user logins and info? Note: it HAS to be secure and relatively simple to learn for someone with moderate programming experience. Update: I understand that CMSs offer good tools for logins etc. but I want to do this all by myself.

  • simple toggle problem

    - by meo
    I'm just programming a little function that toggles a content by fading it in and out. this.advancedSearch = function(fieldset, triggerBtn){ fieldset.hide() triggerBtn.click(function(){ fieldset.toggle(function(){ $(this).stop(false, true).fadeIn(300) }, function(){ $(this).stop(false, true).fadeIn(300) }) }) } if just I use toggle() it works, but when i insert the two functions nothing happens and no error is thrown. Is there something i have done wrong?

  • upload an m4a file in flex, saving it as a blob in oracle, and retrieving metadata info from it

    - by Angus
    Hi, I currently have a FileUpload.mxml component that uploads a .m4a to an oracle database, retrieves metadata from the file and saves the metadata info in the database. to acheive this I use FileReference() and set up, amoung others, the dispatcher.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler); So the file is posted to a php file which saves it as a blob. Once the blob is saved, the script sends a message back to flex to dispatch the upload_complete_data event. In the complete handler, the metadata is then retreived by reading the value back from the database into a custom made meta data reader. The metadata info is then saved via flex. This seems a little long winded. Has anyone else successfully achieved this using a different way?

  • Reading from the HTML DOM returns UTF-8 characters

    - by teehoo
    I have a contenteditable div where I'm reading individual characters and sending them off to a server (for more background this is similar to Google Wave where typing a character automatically sends it) I was using a plain old html textfield before and everything worked fine until I "upgraded" to a contenteditable div. My problem is that now the characters are in UTF-8 format, which is causing some weird problems on the server that I would rather not debug. It would be much easier to force everything to be ASCII on the client side. Is there any way to do this? I tried putting in a meta tag stating the html file is charset=ISO-8859-1, but it doesnt seem to work. Reading from the div tag still returns UTF-8 codes. (One example is when I press space I get the pair 0xC2 0xA0 which corresponds to a "non-breaking white space"

  • Order database results by bayesian rating

    - by One Trick Pony
    I'm not sure this is even possible, but I need a confirmation before doing it the "ugly" way :) So, the "results" are posts inside a database which are stored like this: the posts table, which contains all the important stuff, like the ID, the title, the content the post meta table, which contains additional post data, like the rating (this_rating) and the number of votes (this_num_votes). This data is stored in pairs, the table has 3 columns: post ID / key / value. It's basically the WordPress table structure. What I want is to pull out the highest rated posts, sorted based on this formula: br = ( (avg_num_votes * avg_rating) + (this_num_votes * this_rating) ) / (avg_num_votes + this_num_votes) which I stole form here. avg_num_votes and avg_rating are known variables (they get updated on each vote), so they don't need to be calculated. Can this be done with a mysql query? Or do I need to get all the posts and do the sorting with PHP?

  • FieldError when annotating over foreign keys

    - by X_9
    I have a models file that looks similar to the following: class WithDate(models.Model): adddedDate = models.DateTimeField(auto_now_add=True) modifiedDate = models.DateTimeField(auto_now=True) class Meta: abstract = True class Match(WithDate): ... class Notify(WithDate): matchId = models.ForeignKey(Match) headline = models.CharField(null=True, blank=True, max_length=10) For each Match I'm trying to get a count of notify records that have a headline. So my call looks like matchObjs = Match.objects.annotate(notifies_made=Count('notify__headline__isnull')) This keeps throwing a FieldError. I've simplified the query down to matchObjs = Match.objects.annotate(notifies_made=Count('notify')) And I still get the same FieldError... I've seen this work in other cases (other documentation, other SO questions like this one) but I can't figure out why I'm getting an error. The specific error that is returned is as follows: Cannot resolve keyword 'notify' into field. Choices are: (all fields from Match model) Does anyone have a clue as to why I can't get this annotation to work across tables? I'm baffled after looking at the other SO question and various Django docs where I've seen this done. Edit: I am using Django 1.1.1

  • How to read tags out of m4a files in .NET?

    - by dkackman
    I've got some heavily modified code that ultimately came from the Windows Media SDK that works great for reading tags out of MP3 and WMV files. Somewhere along the line, Windows Media Player added support for .m4a files (was it in Windows 7?) but the Windows Media API doesn't seem to reflect that addition (or at least IWMMetadataEditor2::OpenEx pukes on an .m4a file). What would be some good C# code or links on how to dig meta data tags out of m4a files? (Google has come up dry on the C# front.) UPDATE AtomicParsley did indeed end being the best approach. Since that code is a command line tool however I ended up having to create a managed wrapper around some of its functionality in order to use in-process. It is posted on google code if anyone else needs such a thing.

  • Prepending to a multi-gigabyte file.

    - by dafmetal
    What would be the most performant way to prepend a single character to a multi-gigabyte file (in my practical case, a 40GB file). There is no limitation on the implementation to do this. Meaning it can be through a tool, a shell script, a program in any programming language, ...

    - by ritu
    I have been programming for about 10 years: 7 years C++, 3 years MFC, 2 JSP/Servlets, and the last year .NET (since there was some overlap the total won't add up). The problem is now that I am looking for a new job, I don't know what the latest thing is in C++ AND Java AND .NET AND MFC and somehow at interviews I am expected to KNOW everything about these topics because I have them listed on my resume. Any suggestions?

  • If as assert fails, is there a bug?

    - by RichAmberale
    I've always followed the logic: if assert fails, then there is a bug. Root cause could either be: Assert itself is invalid (bug) There is a programming error (bug) (no other options) I.E. Are there any other conclusions one could come to? Are there cases where an assert would fail and there is no bug?

    I am trying to create a class for network programming. This will create a general purpose socket with thread. But when I tried to creat the thread using createthread(). The third argument is producing errors. And from the net I came to know that I can't use the member functions as a argument to the createthread(). Is there any thing by which I can achieve this.

  • Expanding Git SHA1 information into a checkin without archiving?

    - by Tim Lin
    Is there a way to include git commit hashes inside a file everytime I commit? I can only find out how to do this during archiving but I haven't been able to find out how to do this for every commit. I'm doing scientific programming with git as revision control, so this kind of functionality would be very helpful for reproducibility reasons (i.e., have the git hash automatically included in all result files and figures).

  • Client-side session timeout redirect in ASP.Net

    - by Mercury821
    I want to build a way to automatically redirect users to Timeout.aspx when their session expires due to inactivity. My application uses forms authentication and relies heavily on update panels within the same aspx page for user interaction, so I don't want to simply redirect after a page-level timer expires. For the same reason, I can't use '<meta http-equiv="refresh"/>' What I want to do is create a simple ajax web service with a method called IsSessionTimedOut(), that simply returns a boolean. I will use a javascript timer to periodically call the method, and if it returns true, then redirect to Timeout.aspx. However, I don't want calling this method to reset the session timeout timer, or the session would never time out because of the service call. Is there a clean way to avoid this catch-22? Hopefully there is an easy solution that has so far eluded me.
