  • Google App Engine Project hierarchy

    - by Ron
    Hey guys, I'm working on a google app engine (with Django) and I just can't figure out what's a good practice for folder hierarchy.. I've looked at this: Project structure for Google App Engine but one thing isn't clear - what if I have static folder (like js files) that are unique to my app, not project? where do they go? my current hierarchy is: proj static ** js ** css myapp ** templates So when a template inside my app sends a GET for js/script.js. this gets redirected to /myapp/js/script.js, which my server doesn't recognize. here is my project url.py: urlpatterns = patterns('', (r'^myapp/', include('myapp.urls')), ) and here is my myapp.urls.py: urlpatterns = patterns('myapp.views', (r'^$', 'myapp.views.index'), ) how should I rearrange this to work? thanks!

  • How do I do multipled level routes best in MVC

    - by Lilja
    I have a site where I would like an URL like: /Some maincategory name/{id}/Some subcategory name/{id}/Some item name/{id} I include the IDs of each level since the name is not unique. This is doable but I have to create a new routing for each level. My Html.ActionLink also looks nasty. Each level has it's own controller since the levels are completely different. The URLs could be something like this: _/Birds/2/Waders/4/Flamingos/23_ _/Mammals/5/Dogs/23/Longeared/25/Somedog/76_ _/Insects/7/Spiders_ This is just an example and not what I'm going to use. My applications has nothing to do with animals. Is there a good way of doing this or should I use the standard routing instead?

  • Maximizing the number of threads to fully utilize all available resources without hindering overall

    - by Matt
    Let's say I have to generate a bunch of result files, and I want to make it as fast as possible. Each result file is generated independently of any other result file; in fact, one could say that each result file is agnostic to every other result file. The resources used to generate each result file is also unique to each. How can I dynamically decide the optimal number of threads to run simultaneously in order to minimize the overall run time? Is my only option to write my own thread manager that watches performance counters and adjust accordingly or does there exists some solid classes that already accomplish this?

  • gethostbyname in C

    - by Matic
    I don't know how to write applications in C, but I need a tiny program that does: lh = gethostbyname("localhost"); output = lh->h_name; output variable is to be printed. The above code is used in PHP MongoDB database driver to get the hostname of the computer (hostname is part of an input to generate an unique ID). I'm skeptical that this will return the hostname, so I'd like some proof. Any code examples would be most helpful. Happy day, Matic

  • Display field from another table in SQL

    - by Roland Bengtsson
    I'm a newbie with SQL... Now I want to do display some instances of AddrDistances from DevExpress CxGrid with SQL. Select Cast((DistanceAsMeters * 0.001) as Decimal(8,1)) DistanceAsKm, bold_id, created, fromAddress, toAddress From AddrDistance Where DistanceAsMeters = 0 and PseudoDistanceAsCostKm = 0 and not AddrDistance.bold_id in (select bold_id from DistanceQueryTask) Order By Created Desc This SQL is working and the result is: DistanceAsKM Bold_ID Created FromAddress ToAddress 0 134808 16.02.2010 121795 134570 0 121701 10.03.2010 120850 122991 The result I want is this: DistanceAsKM Bold_ID Created FromAddress ToAddress 0 134808 16.02.2010 Kalmar Stockholm 0 121701 10.03.2010 Falkenberg Oslo So the amount of rows is right but I want to replace the numbers in FromAddress and ToAddress with strings from another table. The numbers shows here is just the boldid. Every object in the database have an unique boldid. The addresses above is stored in table Address and it have a City field with the column and a boldid as a key. What should I write in SQL to get this right ? Is there something in the CxGrid that could help here ? Regards

  • Overriding PEAR error handler

    - by Rolf
    Hi everyone, I'm currently working on an application that requires lots of external libraries. My job right now is set a unique error handler that will manage every error. So far, I found 7 different types of PEAR errors: PEAR_ERROR_RETURN: PEAR_ERROR_EXCEPTION: PEAR_ERROR_CALLBACK: PEAR_ERROR_EXCEPTION: PEAR_ERROR_PRINT: PEAR_ERROR_TRIGGER: PEAR_ERROR_DIE: I want to handle only the serious error (like the native E*_ERROR). The only problem is I have absolutely no idea about PEAR error criticity ! Those names are more related to the way of handling them than to their seriousness... Is there a real documentation about it ? I guess a better solution would consist in using their pushErrorHandling, but I just don't understand how to use it... If someone here knows, I'd be grateful... Thanks in advance !

  • Selecting contents of Label Control

    - by j-t-s
    Hi All I have what I consider to be a pretty unique problem here, and no idea how to implement. From what I've seen, there is no documentation, tutorials, samples and/or articles on this. I've spent weeks researching, with nothing to show. The problem: I need the user to be able to select the contents of a Label Control at runtime, and edit it. If this can be done by extending the existing Label control, great! Or, if this requires a whole new Label Control to be created, fine. So be it. Using a TextBox is not an option I'm afraid. Any help at all is greatly appreciated! Thank you, jase

  • How do people manage changes to common library files stored across mutiple (Mercurial) repositories?

    - by mckoss
    This is perhaps not a question unique to Mercurial, but that's the SCM that I've been using most lately. I work on multiple projects and tend to copy source code for libraries or utilities from a previous project to get a leg up on starting a new project. The problem comes in when I want to merge all the changes I made in my latest project, back into a "master" copy of those shared library files. Since the files stored in disjoint repositories will have distinct version histories, Mercurial won't be able to perform an intelligent merge if I just copy the files back to the master repo (or even between two independent projects). I'm looking for an easy way to preserve the change history so I can merge library files back to the master with a minimum of external record keeping (which is one of the reasons I'm using SVN less as merges require remembering when copies were made across branches). Perhaps I need to do a bit more up-front organization of my repository to prepare for a future merge back to a common master.

  • database vs flat file, which is a faster structure for regex matching with many simultaneous request

    - by Jamex
    Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching using regex against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? TIA

  • Why does C# not implement GetHashCode for Collections?

    - by Peterdk
    I am porting something from Java to C#. In Java the hashcode of a ArrayList depends on the items in it. In C# I always get the same hashcode from a List... Why is this? For some of my objects the hashcode needs to be different because the objects in their list property make the objects non-equal. I would expect that a hashcode is always unique for the object's state and only equals another hashcode when the object is equal. Am I wrong?

  • phonegap crossplatform redirection to local file

    - by Marco Gagliardi
    Hi I'm developing a phonegap + JQueryMobile app, which should be correctly executed on Android, iOs and WindowsPhone as well. I need to exploit an external service wich requires one callback url to redirect the app to in case of success, and one in case of error (pretty common situation. In my case both will be local files, say www/success.html and www/error.html). Of course I could write different paths for each device (e.g. file:///android_asset/www/success.html on Android), but i'm wondering if the framework provide a more simple elegant solution. So the questions is, how can i get a unique absolute URL wich allows me to perform a cross-platform HTTP redirection from a remote web page to a local file within a phonegap application? Thanks

  • Concatenating databases with Squeryl

    - by Pengin
    I'm trying to use Squeryl to take the contents of a table from one database, and append it to the equivalent table in another database. The primary key will have to be reassigned in the process, but I'm getting the error NULL not allowed for column "SIMID". Why is this? object Concatenator { def main(args: Array[String]) { Class.forName("org.h2.Driver"); val seshA = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsA", "sa", "password"), new H2Adapter ) val seshB = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsB", "sa", "password"), new H2Adapter ) using(seshA){ import Library._ from(sims){s => select(s)}.foreach{item => using(seshB){ sims.insert(item); } } } } case class Simulation( @Column("SIMID") var id: Long, val date: Date ) extends KeyedEntity[Long] object Library extends Schema { val sims = table[Simulation] on(sims)(s => declare( s.id is(unique, indexed, autoIncremented) )) } }

  • What keying option does the keychain use?

    - by Rudiger
    I have read into the keychain and have found that it uses Triple DES. What I can't find is what keying option it uses. I am guessing / hoping that its keying option 1 where all 3 passwords are unique but if thats the case I can only think of two passwords it can use (user password and App ID that comes from your dev cert) so where is the third coming from? Is it a key private to Apple? If its keying option 2 (first and third key are the same) it might not be secure enough for our company to rely on. Although that might sound paranoid I have to justify to our security department that it is secure enough.

  • [C#] How to consume web service adheres to the Event-based Asynchronous Pattern?

    - by codemonkie
    I am following the example from http://msdn.microsoft.com/en-us/library/8wy069k1.aspx to consume a web service implemented (by 3rd party) using the Event-based Asynchronous Pattern. However, my program needs to do multiple calls to the DoStuffAsync() hence will get back as many DoStuffCompleted. I chose the overload which takes an extra parameter - Object userState to distinguish them. My first question is: Is it valid to cast a GUID to Object as below, where GUID is used to generate unique taskID? Object userState = Guid.NewGuid(); Secondly, do I need to spawn off a new thread for each DoStuffAsync() call, since I am calling it multiple times? Also, would be nice to have some online examples or tutorials on this subject. (I've been googling for it the whole day and didn't get much back) Many thanks

  • Why does MySQL autoincrement increase on failed inserts?

    - by Sorcy
    A co-worker just made me aware of a very strange MySQL behavior. Assuming you have a table with an auto_increment field and another field that is set to unique (e.g. a username-field). When trying to insert a row with a username thats already in the table the insert fails, as expected. Yet the auto_increment value is increased as can be seen when you insert a valid new entry after several failed attempts. For example, when our last entry looks like this... ID: 10 Username: myname ...and we try five new entries with the same username value on our next insert we will have created a new row like so: ID: 16 Username: mynewname While this is not a big problem in itself it seems like a very silly attack vector to kill a table by flooding it with failed insert requests, as the MySQL Reference Manual states: "The behavior of the auto-increment mechanism is not defined if [...] the value becomes bigger than the maximum integer that can be stored in the specified integer type." Is this expected behavior?

  • PHP Dynamic include based on current file path

    - by Adrian M.
    Hello, I want to find a method to include some files based on the current file path.. for example: I have "website.com/templates/name1/index.php", this "index.php should be a unique file that I will use in many different directories on different depths, so I want to make the code universal so I don't need to change anything inside this file.. So if this "index.php" is located in "website.com/templates/name1/index.php" than it should include the file located here: "website.com/content/templates/name1/content.php" another example: "website.com/templates/name2/index.php" than it should include the file located here: "website.com/content/templates/name2/content.php" Also I want to overrun "*Warning: include_once() [function.include-once]: http:// wrapper is disabled in the server configuration by allow_url_include=0*" kind of error.. because is disabled and unsafe.. Is there a way to achieve this? Thank you!

  • Instantiating a python class in C#

    - by Jekke
    I've written a class in python that I want to wrap into a .net assembly via IronPython and instantiate in a C# application. I've migrated the class to IronPython, created a library assembly and referenced it. Now, how do I actually get an instance of that class? The class looks (partially) like this: class PokerCard: "A card for playing poker, immutable and unique." def __init__(self, cardName): The test stub I wrote in C# is: using System; namespace pokerapp { class Program { static void Main(string[] args) { var card = new PokerCard(); // I also tried new PokerCard("Ah") Console.WriteLine(card.ToString()); Console.ReadLine(); } } } What do I have to do in order to instantiate this class in C#?

  • More strict query yields more results?

    - by Mark
    I've got a query that looks like this affiliates = User.objects.annotate(referral_count=Count('referrals')).filter(referral_count__gt=0) But when I restrict it more by adding referrals__user__date_joined__gt=start_date to the filter, I get even higher referral counts. I'm trying to count the number of people a user has referred within a time period. The relevant model looks like this: class Profile(models.Model): user = models.ForeignKey(User, unique=True, related_name='profile') referred_by = models.ForeignKey(User, null=True, blank=True, related_name='referrals') In contrast, when I try it like this: affiliates = User.objects \ .exclude(referrals__user__date_joined__lte=sd, referrals__user__date_joined__gt=ed) \ .annotate(referral_count=Count('referrals')) \ .filter(referral_count__gt=0) The exclude statement seems to do nothing... the counts don't change (should be 0 if no referred users have joined within that time period, but it isn't).

  • Android Template Application?

    - by stormin986
    I have built an application that I want to use as the foundation for a few other variants. The variants will come from assets / resource files and a unique AndroidManifest.xml. However, I want to be able to leave all the application code alone (modifying the package of all my classes, etc). I'm having a hard time figuring out how to do so. My first thought was to simply have my main application in its own package, and then specify the specific application package in the manifest. However, this gives me issues with the generated R.java class, since it is generated to be in the main application's package. Anyone have any thoughts on how to accomplish this? To have a code baseline, and the application variants happen in resources/assets and the manifest?

  • Is it better to comment out unneeded code or delete it?

    - by Matt Connolly
    For web applications under maintenance, assuming you have source control, when you need to remove part of the UI and the associated code, do you delete the code and check in, or do you comment out the old code? Arguments in favor of deleting: cleaner code, can still see deleted code in source control history, no worrying about refactoring code that might be uncommented some day. Arguments in favor of commenting: sometimes you need to add the feature back in and the developer adding it back in may not know to check source control history, sometimes the code represents unique functionality that can be a handy reference, seeing it all in one place can help provide clues to deciphering the active code.

  • "partial views" best practices for 'container' divs?

    - by ropstah
    What is the 'best' way to handle the html markup for partial views? (which are also refreshed using AJAX) The biggest issue I run into is where to place the 'container' div... Consider having a masterpage and a partial view. (class="" could be interchanged with id="" depending if the partial is guaranteed to be unique, however this isn't really important to the issue i think) Masterpage: <div id="place1" class="placeholder"> <!-- render partial --> </div> Partial: <div id="partial1" class="partial"> <!-- content --> </div> I feel that something isn't being done right. However I cannot remove the div in the masterpage, because I need that to 'encapsulate' the response from AJAX partial updates. And also I cannot move the div in the partial to the masterpage, because that would require to move 'partial' info to the masterpage... How do you handle this?

  • Complicated MySQL query?

    - by Scott
    I have two tables: RatingsTable that contains a ratingname and a bit whether it is a positive or negative rating: Good 1 Bad 0 Fun 1 Boring 0 FeedbackTable that contains feedback on things...the person rating, the rating and the thing rated. The feedback can be determined if it's a positive or negative rating based on RatingsTable. Jim Chicken Good Jim Steak Bad Ted Waterskiing Fun Ted Hiking Fun Nancy Hiking Boring I am trying to write an efficient MySQL query for the following: On a page, I want to display the the top 'things' that have the highest proportional positive ratings. I want to be sure that the items from the feedback table are unique...meaning, that if Jim has rated Chicken Good 20 times...it should only be counted once. At some point I will want to require a minimum number of ratings (at least 10) to be counted for this page as well. I'll want to to do the same for highest proportional negative ratings, but I am sure I can tweak the one for positive accordingly.

  • Does a System.DirectoryServices.AccountManagement.Principal ever have a null GUID?

    - by Josh
    I have a situation where I need to store a globally unique identifier that points to an Active Directory user account. I'm leaning towards the Guid because it is easier to store than the Sid. According to the MSDN entry, the property (which is a Nullable), will always return null if the ContextType is set to "Machine." I don't need to worry about this because our ContextType will always be set to "Domain." My question is, will this property ever return null if the ContextType is "Domain"? In other words, will an account in an AD DS store always have a Guid?

  • How do I add a one-to-one relationship in MYSQL?

"recid" is a recommended song for that user. I hope to have a list of pid's, and then recommended songs for each person. Of course, in my 2nd table, (pid, recid) would be unique key. How do I do a one-to-one query for this ?
