  • ColdFusion structs Direct Assignment vs object literal notation.

    - by Tom Hubbard
    The newer versions of ColdFusion (I believe CF 8 and 9) allow you to create structs with object literal notation similar to JSON. My question is, are there specific benefits (execution efficiency maybe) to using object literal notation over individual assignments for data that is essentially static? For example: With individual assignments you would do something like this: var user = {}; user.Fname = "MyFirstnam"; user.Lname = "MyLastName"; user.titles = []; ArrayAppend(user.titles,'Mr'); ArrayAppend(user.titles,'Dr.'); Whereas with object literals you would do something like. var user = {Fname = "MyFirstnam", Lname = "MyLastName", titles = ['Mr','Dr']}; Now this limited example is admittedly simple, but if titles was an array of structures (Say an array of addresses), the literal notation becomes awkward to work with.

  • .htaccess Subfolder Redirect

    - by John K
    Hey Guys & Gals, I recently moved my WordPress website to a subfolder. I want to add a redirect in the .htaccess file so that the links to images I've uploaded originally to ~/wp-content/uploads/ will pass to ~/blog/wp-content/uploads. The .htaccess file must remain in the root folder for WordPress to read it properly. This is what I tried Redirect /wp-content/uploads/ /blog/wp-content/uploads That worked great, except I host other domains on this account, and all of the other domain's upload folders were being redirected in a similar manner. Is there a way to restrict this redirect to just one domain? So that example.com/wp-content/uploads redirects to example.com/blog/wp-content/uploads, but another.com/wp-content/uploads does not? Thanks everyone!

  • Injecting raw TCP packets with Python

    - by Evgeniy Arbatov
    Hello! What would be a suitable way to inject a raw TCP packet with Python? For example, I have the payload consisting of hexadecimal numbers and I want to send that sequence of hexadecimal numbers to a network daemon: so that if I choose to send 'abcdef', I see 'abcdef' on the wire too. But not '6162636566' as in the case of: new = socket.socket(socket.AF_INET, socket.SOCK_STREAM) new.connect(('127.0.0.1', 9999)) new.send('abcdef') Can I use Python's SOCK_RAW for this purpose? If so, can you give me an example of sending raw TCP packets with SOCK_RAW (since I did not get it working myself) Thanks! Evgeniy

  • Blogger (Python) API: How do I retrieve a post by post ID?

    - by larsks
    Having previously obtained a post ID from a call to gdata.blogger.client.add_post()... post = client.add_post(...) post_id = post.get_post_id() ...how do I use that post id to retrieve the post in the future? I thought maybe gdata.blogger.client.Query would be the way to go, but this doesn't support post id as a query term. The example code distributed with the Python gdata module doesn't have an example of this use case, and after poking around gdata.blogger.client.* for a while I'm not making much progress. I could obviously iterate through all the posts in the blog until find the one with the corresponding id, but that would be a terrible, terrible idea.

  • Translate google co-ordinates to the pixels on picture.

    - by kalininew
    I have a city "map" (for example - Moscow). She in accuracy repeats the contours the given city in google maps (that is it is copied from google maps and it is a little processed, but the sense remained the same). Also I have object co-ordinates in a city (in co-ordinates of google). Problem: how to translate google co-ordinates to the co-ordinates of my picture (that is in pixels on OX and OY on a picture). That is I receive google-co-ordinates and it is necessary for me to draw this point on my picture. I know that on small scales (for example on city scales) it to make simply enough (it is necessary to learn what google-co-ordinates has one of picture corners, then to learn "price" of one pixel in google-co-ordinates on a picture on axes OX and OY separately). But on the big scales (country scale) "price" of one pixel will be not a constant, and will vary strongly enough and the method described above cannot be applied. How to solve a problem on country scales?

  • ASP.NET MVC Data passing

    - by user295541
    Hi, I need a good example or guideline which could give me a pattern for data passing between view and partial view. For example I have a view which contains several partial views. I refresh these partial view by ajax. So I need to pass data among view and its partial views. The best way would be if I could pass data without using Temp data dictionary. Anybody know a good article about this? l.

  • jQuery event handlers always execute in order they were bound - any way around this?

    - by asgeo1
    It can be anoying that jQuery event handlers always execute in the order they were bound. For example: $('span').click(doStuff1()); $('span').click(doStuff2()); clicking on the span will cause doStuff1() to fire, followed by doStuff2(). At the time I bind doStuff2(), I would like the option to bind it before doStuff1(), but there doesn't appear to be any easy way to do this. I suppose most people would say, just write the code like this: $('span').click(function (){ doStuff2(); doStuff1(); }); But this is just a simple example - in practise it is not always convienient to do that. There are situations when you want to bind an event, and the object you are binding to already has events. And in this case you may simply want the new event to fire before any other existing events. So what is the best way to achieve this in jQuery?

  • How to show an animated spinner while a background task is processing in nested rails model using aj

    - by Globalkeith
    My specific example is highly complex, so I will use the example shown by Ryan from Railscasts to discuss this: http://railscasts.com/episodes/197-nested-model-form-part-2 Background I have a form, let's say "Survey", which contains an arbitrary number of "Questions". Senario Give i am on the "Edit Survey" page. I would like to add a button to each "Question" field which calls a remote_function, which in turn queue's up a delayed_job to execute some processing on the "Question". To give feedback to the user, i would like to disable the button, and show an animated spinner, which remains until the delayed_job has processed the "Question". Hint - I can add methods to the "Question" model to indicate the status of the delayed_job. So, with best practices in mind, what is the best way to achieve this?

  • Pyramid.security: Is getting user info from a database with unauthenticated_userid(request) really secure?

    - by yourfriendzak
    I'm trying to make an accesible cache of user data using Pyramid doc's "Making A “User Object” Available as a Request Attribute" example. They're using this code to return a user object to set_request_property: from pyramid.security import unauthenticated_userid def get_user(request): # the below line is just an example, use your own method of # accessing a database connection here (this could even be another # request property such as request.db, implemented using this same # pattern). dbconn = request.registry.settings['dbconn'] userid = unauthenticated_userid(request) if userid is not None: # this should return None if the user doesn't exist # in the database return dbconn['users'].query({'id':userid}) I don't understand why they're using unauthenticated_userid(request) to lookup user info from the database...isn't that insecure? That means that user might not be logged in, so why are you using that ID to get there private info from the database? Shouldn't userid = authenticated_userid(request) be used instead to make sure the user is logged in? What's the advantage of using unauthenticated_userid(request)? Please help me understand what's going on here.

  • Should i really use integer primary IDs?

    - by arthurprs
    For example, i always generate an auto-increment field for the users table, but i also specifies an UNIQUE index on their usernames. There is situations that i first need to get the userId for a given username and then execute the desired query. Or use a JOIN in the desired query. It's 2 trips to the database or a JOIN vs. a varchar index The above is just an example There is a real performance benefit on INT over small VARCHAR indexes? Thanks in advance!

  • In database table design, how does "Virtual Goods" affect table design -- should we create an instan

    - by Jian Lin
    When we design a database table for a DVD rental company, we actually have a movie, which is an abstract idea, and a physical DVD, so for each rental, we have a many-to-many table with fields such as: TransactionID UserID DvdID RentedDate RentalDuration AmountPaid but what about with virtual goods? For example, if we let a user rent a movie online for 3 days, we don't actually have a DVD, so we may have a table: TransactionID UserID MovieID RentedDate RentalDuration AmountPaid should we create a record for each instance of "virtual good"? For example, what if this virtual good (the movie) can be authorized to be watched on 3 devices (with 3 device IDs), then should we then create a virtual good record in the VirtualGoods table, each with a VirtualGoodID and then another table that has VirtualGoodID DeviceID to match up the movie with the DeviceIDs? We can also just use the TransactionID as the VirtualGoodID. Are there circumstances where we may want to create a record to record this "virtual good" in a VirtualGoods table?

  • Are there any JSF components for implementing breadcrumb navigation?

    - by kazanaki
    As far as I know there are two "kinds" of breadcrumbs. The static/hierarchy one Works like a stack Entries are pushed when a user goes "deeper" into the site Entries are poped when user goes "up" into the site Is the same for all users (for a given page) Shows location rather than history A simple Example would be HOME - BIG CATEGORY - SMALL CATEGORY - ARTICLE The dynamic/historical one Works like a queue Entries are pushed at the end when a user goes to another page Entries are removed from the front when the maximum size is reached Is different for each user, since it is personalized. Shows timeline/history instead of location. A simple example would be SMALL CATEGORY - HOME - BIG CATEGORY - HOME The question is: Are there any ready-made JSF component for these types of navigation?

  • How to log in to a website using installed twill?

    - by brilliant
    Hello, everybody!!!! I have just successfully installed TWILL on my computer with the help of one very supportive member of "StackOverflow" (you can check it out HERE) and have tried to run one of the simple examples on the twill documentation page (you can see that page HERE). Here is that example: Let's say my username on www.slash.org is lynxye and my password is mammal. When I try to enter that example code into my Python prompt, I can only type and enter the first line of the code because when I click on "Enter" to start a new line, I get some error messages right away: The same happens when I try to enter this code into my terminal: I think I miss out on some basics here. Perhaps, I need to create a file that would contain that code and then run that file somehow, but I really don't know where I need to create that file and with what extensdion. Can anyone, please, help me with this?

  • Non RBAC User Roles and Permissions System: a role with properties

    - by micha12
    We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case. This is my second question (the first question is here: http://stackoverflow.com/questions/2839797/non-rbac-user-roles-and-permissions-system-checking-the-users-city). We have the following case: we need to implement a Manager role in our web application. However, a Manager can belong to one or several companies (within a big group of companies for which we are creating this web app). Say, there can be “Manager of companies A and B”, “Manager of company C”, etc. Depending on the companies that the Manager belongs, he has access to certain operations: for example, he can communicate with clients only of those companies that he belongs to. That is, “Manager of companies A and B” can only have contacts with clients of companies A and B, and not with those of company C. He can also view clients’ details pages of companies A and B and not of C, etc. It seems that this case falls within the RBAC. However, this is not really the case. We will need to create a ManagerRole class that will have a Companies property – that is, this will not be just a role as a collection of permissions (like in the classical RBAC), but a role with properties! This was just one example of a role having properties. There will be others: for example, an Administrator role that will also belong to a number of companies and will also have other custom properties. This means that we will a hierarchy or roles classes: class Role – base class class ManagerRole : Role List Companies class AdministratorRole : Role List Companies Other properties We investigated pure RBAC and its implementation in several systems, and found no systems featuring a hierarchy or roles, each having custom properties. In RBAC, roles are just collections of permissions. We could model our cases using permission with properties, like ManagerPermission, AdministratorPermission, but this has a lot of drawbacks, the main being that we will not be able to assign a role like “Manager of Companies A and B” to a user directly, but will have to create a role containing a ManagerPermission for companies A and B… Moreover, a "Manager" seems to be rather a "role" (position in the company) rather than a "permission" from the linguistic point of view. Would be grateful for any ideas on this subject, as well as any experience in this field! Thank you.

  • Why does Maven have such a bad rep?

    - by Dan
    There is a lot of talk on the internet about how Maven is bad. I have been using some features of Maven for a few years now and the most important benefit in my view is the dependency management. Maven documentation is less than adequate, but generally when I need to accomplish something I figure it once and than it works (for example, I remember when I implemented signing the jars.) I don’t think that Maven is great, but it does solve some problems that without it would be a genuine pain. So, why does Maven has such a bad rep and what problems with Maven can I expect in the future? Maybe there are much better alternatives that I don't know about? (For example, I never looked Ivy in detail.) NOTE: This is not an attempt to cause an argument. It is an attempt to clear the FUD.

  • Error inflating class android.widget.CompoundButton

    - by snctln
    [Disclaimer: This has been cross posted on the Android Developers Google Group I am trying to use a CompoundButton in a project I am working on. Every time I try and use it by declaring it in my layout xml file I receive the error "01-04 12:27:46.471: ERROR/AndroidRuntime(1771): Caused by: android.view.InflateException: Binary XML file line #605: Error inflating class android.widget.CompoundButton" After fighting the error for a half an hour I decided to try a minimalistic example. I am using the latest eclipse developer tools, and targeting android 2.2 makign the minimum sdk required 2.2 (8). Here is the activity java code: package com.example.CompoundButtonExample; import android.app.Activity; import android.os.Bundle; public class CompoundButtonExampleActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } Here is the layout xml code: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <CompoundButton android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> Here is the manifest xml code: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.CompoundButtonExample" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".CompoundButtonExampleActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="8" /> </manifest> As you can see it is just the default hello world project that eclipse creates for you when you start a new Android project. It only differs in the fact that I add a "CompoundButton" to the main layout in a vertical LinearLayout. Can anyone confirm this bug? Or tell me what I am doing wrong?

  • PyGTK: dynamic label wrapping

    - by detly
    It's a known bug/issue that a label in GTK will not dynamically resize when the parent changes. It's one of those really annoying small details, and I want to hack around it if possible. I followed the approach at 16 software, but as per the disclaimer you cannot then resize it smaller. So I attempted a trick mentioned in one of the comments (the set_size_request call in the signal callback), but this results in some sort of infinite loop (try it and see). Does anyone have any other ideas? (You can't block the signal just for the duration of the call, since as the print statements seem to indicate, the problem starts after the function is left.) The code is below. You can see what I mean if you run it and try to resize the window larger and then smaller. (If you want to see the original problem, comment out the line after "Connect to the size-allocate signal", run it, and resize the window bigger.) The Glade file ("example.glade"): <?xml version="1.0"?> <glade-interface> <!-- interface-requires gtk+ 2.16 --> <!-- interface-naming-policy project-wide --> <widget class="GtkWindow" id="window1"> <property name="visible">True</property> <signal name="destroy" handler="on_destroy"/> <child> <widget class="GtkLabel" id="label1"> <property name="visible">True</property> <property name="label" translatable="yes">In publishing and graphic design, lorem ipsum[p][1][2] is the name given to commonly used placeholder text (filler text) to demonstrate the graphic elements of a document or visual presentation, such as font, typography, and layout. The lorem ipsum text, which is typically a nonsensical list of semi-Latin words, is a hacked version of a Latin text by Cicero, with words/letters omitted and others inserted, but not proper Latin[1][2] (see below: History and discovery). The closest English translation would be "pain itself" (dolorem = pain, grief, misery, suffering; ipsum = itself).</property> <property name="wrap">True</property> </widget> </child> </widget> </glade-interface> The Python code: #!/usr/bin/python import pygtk import gobject import gtk.glade def wrapped_label_hack(gtklabel, allocation): print "In wrapped_label_hack" gtklabel.set_size_request(allocation.width, -1) # If you uncomment this, we get INFINITE LOOPING! # gtklabel.set_size_request(-1, -1) print "Leaving wrapped_label_hack" class ExampleGTK: def __init__(self, filename): self.tree = gtk.glade.XML(filename, "window1", "Example") self.id = "window1" self.tree.signal_autoconnect(self) # Connect to the size-allocate signal self.get_widget("label1").connect("size-allocate", wrapped_label_hack) def on_destroy(self, widget): self.close() def get_widget(self, id): return self.tree.get_widget(id) def close(self): window = self.get_widget(self.id) if window is not None: window.destroy() gtk.main_quit() if __name__ == "__main__": window = ExampleGTK("example.glade") gtk.main()

  • How do you separate the template of a blog block in Drupal?

    - by Ralph
    Hi, In Drupal, I created a block using views. This block contains the latest blog entries. I've placed this on a specific page to display it as an archive. Now, as for the blog itself (for example when one of them is clicked), A blog template for it depends on node-blog.tpl.php. My problem is, when I style node-blog.tpl.php, the block I created for the archives (as it displays on the page) gets affected. For example if I add TEST on node-blog.tpl.php, I will also get that on the block for every entry. I think it's because it is associated to a blog entry? What I want is to have node-blog styled "alone" when blog entries are viewed individually and not get the other entries on the blocks on the archive page be affected. How should I do this?

  • Delete a line from a file in java

    - by dalton conley
    Ok, so I'm trying to delete lines from a text file with java. Currently the way I'm doing this, is I'm keep track of a line number and inputting an index. The index is the line I want deleted. So each time I read a new line of data I increment the line count. Now when I reach the line count that is the same index, I dont write the data to the temporary file. Now this works, but what if for example I'm working with huge files and I have to worry about memory restraints. How can I do this with.. file markers? For example.. place the file marker on the line I want to do delete. Then delete that line? Or is that just too much work?
