  • How do you access config outside of a request in CherryPy?

    - by OrganicPanda
    I've got a webapp running on CherryPy that needs to access the CherryPy config files before a user creates a request. The docs say to use: host = cherrypy.request.app.config['database']['host'] But that won't work outside of a user request. You can also use the application object when you start the app like so: ... application = cherrypy.tree.mount(root, '/', app_conf) host = application.config['database']['host'] ... But I can see no way of accessing 'application' from other classes outside of a user request. I ask because our app looks at several databases and we set them up when the app starts rather than on user request. I have a feeling this would be useful in other places too; so is there any way to store a reference to 'application' somewhere or access it through the CherryPy API?

  • How to detect pending system shutdown on Linux?

    - by Rajorshi
    Hi, I am working on an app where I need to detect system shutdown. However, I have not found any reliable way get a notification on this event. I know that on shutdown, my app will receive a SIGTERM signal followed by a SIGKILL. What I want to know is if there is someway to query if a SIGTERM is part of a shutdown sequence? Does any one know if there is a way to query that programmatically (C API)? As far as I know, the system does not provide any other method to query for an impending shutdowm. If it does, that would solve my problem as well. I have been trying out runlevels as well, but change in runlevels seem to be instantaneous and without any prior warnings.

  • Returning more than one result

    - by Hairr
    I'm using the following code: def recentchanges(bot=False,rclimit=20): """ @description: Gets the last 20 pages edited on the recent changes and who the user who edited it """ recent_changes_data = { 'action':'query', 'list':'recentchanges', 'rcprop':'user|title', 'rclimit':rclimit, 'format':'json' } if bot is False: recent_changes_data['rcshow'] = '!bot' else: pass data = urllib.urlencode(recent_changes_data) response = opener.open('http://runescape.wikia.com/api.php',data) content = json.load(response) pages = tuple(content['query']['recentchanges']) for title in pages: return title['title'] When I do recentchanges() I only get one result. If I print it though, all the pages are printed. Am I just misunderstanding or is this something relating to python? Also, opener is: cj = CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

  • Java - Array's length property

    - by The New Idiot
    We can determine the length of an ArrayList<E> using its public method size() , like ArrayList<Integer> arr = new ArrayList(10); int size = arr.size(); Similarly we can determine the length of an Array object using the length property String[] str = new String[10]; int size = str.length; Whereas the size() method of ArrayList is defined inside the ArrayList class , where is this length property of Array defined ? Is it implemented by JVM or does it reside in any Java API class file ?

  • Why Microsoft not provide for C# a static Win32 class with the most native functions and structures

    - by Oleg
    Everybody who used P/Invoke of Windows API knows a long list of declarations of static functions with attributes like [DllImport ("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)] The declaration of structures copied from Windows headers like WinNT.h or from web sites like www.pinvoke.net take also a lot of place in our programs. Why we all have to spend our time for this? Why Microsoft not give us a simple way to include a line like in old unmanaged programs #include <windows.h> and we would be have access to a static class Native with all or the most Windows functions and structures inside?

  • Google chrome, native client support and development

    - by hbt
    Hey guys, I would like to write a small C++ app and run it on chrome using the native client API. I have a few questions though: 1) I compiled the examples on Ubuntu and ran the code on firefox but can't run it on chrome (using version 5.0.342.7 beta) Do I need to install something? An extension/plugin? 2) I can't find a single online application I could run? Links anyone, I want to see the power of this thing without having to compile the code locally. Thanks for your help, -hbt PS: I don't know what's the policy with asking multiple questions. If it's a problem, let me know and I will create multiple threads.

  • Why does DataInputStream not support integers?

    - by Jason
    I need to read in a list of numbers from a file, none of which are larger than 32767. Originally I was going to use the Scanner class to pull in the data, then I read about DataInputStream. This would work well for me, except that according to the API, it supports all primitive variables EXCEPT ints! Listed are longs, shorts, bytes, chars, booleans, ect, but no ints. I have no need for double precision from the incoming data. Is this a deliberate or unintentional oversight?

  • Getting Google Chrome to Ignore IE Javascript

    - by swajak
    I'm creating a slideshow using javascript that fades images. Awhile back, I discovered that to change the opacity of an image, I have to use a different API, depending on whether the page is viewed in Firefox or IE. Firefox: img.style.opacity = [value 0 to 1]; IE: img.style.filter="progid:DXImageTransform.Microsoft.Alpha(opacity= [value 0 to 100] )"; So, currently, I use <script LANGUAGE="JScript"> for code that is meant for IE. This was suggested in the Mozilla docs. The problem: Chrome thinks my <script LANGUAGE="JScript"> code is valid, when it is not. How to make Chrome ignore the code inside <script LANGUAGE="JScript"> ? Or how to make my opacity code cross-browser?

  • Quering distinct values throught related model

    - by matheus.emm
    Hi! I have a simple one-to-many (models.ForeignKey) relationship between two of my model classes: class TeacherAssignment(models.Model): # ... some fields year = models.CharField(max_length=4) class LessonPlan(models.Model): teacher_assignment = models.ForeignKey(TeacherAssignment) # ... other fields I'd like to query my database to get the set of distinct years of TeacherAssignments related to at least one LessonPlan. I'm able to get this set using Django query API if I ignore the relation to LessonPlan: class TeacherAssignment(models.Model): # ... model's fields def get_years(self): year_values = self.objects.all().values_list('year').distinct().order_by('-year') return [yv[0] for yv in year_values if len(yv[0]) == 4] Unfortunately I don't know how to express the condition that the TeacherAssignment must be related to at least one LessonPlan. Any ideas how I'd be able to write the query? Thanks in advance.

  • How to deal with extra space characters while Reading a CSV file?

    - by Ravi Dutt
    I am reading a CSV file with CSV Open Source API. as shown below: Java Code:--> CSVReader reader = new CSVReader(new FileReader(filePath),'\n'); String[] values; if((read=(reader.readNext()))!=null) { values = (read[0].split(" (?=([^\"]*\"[^\"]*\")*[^\"]*$)",-1)).length; } // code ends here When I read this CSV file line by line and split that line with delimiter. Then after spliting values each value I get contains extra space character after each character in String. Suppose value in file is like "ABC" and I got this after reading from CSV file reader as " A B C " . I used removeAll("\s+","") on each value even after it is not working. Thank You in Advance.

  • how can I send messages to/from a Websphere Message Broker from an embedded C client (no JVM)?

    - by queBurro
    What are my options for pubsubing (or point to point but pubsub is better) messages to and from an IBM message broker from an embedded headless C/C++ linux client that doesn't have a JVM? Ideally we want large file transfer (2GB once per day off of the client) encryption (SSL) reliable ('assured' delivery / QoS2, maybe QoS1 would do) The client in question currently only has exes and some bash scripts, I've been playing with MQTTv3 and RSMB, but for that I'd have to chomp the large files up (and reassemble back home) and I don't want to get into that if there's a transport that will do this for me? I've looked at MQTTv5 (but our client's got no JVM); JMS (no JVM) and XMS? which again looks like it gives me a C API but then needs the JVM to be installed on the client (or am I wrong?) any clues or hints would be appreciated, cheers

  • Qt grabWindow coordinates shifted from GetCursorPos and GetWindowRect

    - by user1391
    In Qt, when I use the QPixmap::grabWindow(hwnd,x,y,h,w) function, the coordinates are shifted slightly, when compared to the coordinates using the windows api functions GetCursorPos and GetWindowRect. i.e. (0,0) from the point of view of GetCursorPos and GetWindowRect is at the very top left of the toolbar at the top of the window. But (0,0) for QPixmap::grabWindow is more "inside" (i.e. ignoring the window frame). How can I make these 2 coordinates consistent? Especially since the user might have different thicknesses for the window frame?

  • Multithread Communication

    - by Robert
    I'm creating a WPF application that uses a custom object to populate all the controls. The constructor of that object is initiated by an EventHandler that waits for an API. The problem I'm having is when I try to access any information from that object using a button for example, it returns an error saying "The calling thread cannot access this object because a different thread owns it". I'm assuming this is because the EventHandler creates a new thread which doesn't allow the MainThread to have access to it. Any ideas on how to get around this?

  • AES acceleration for Java

    - by chris_l
    I want to encrypt/decrypt lots of small (2-10kB) pieces of data. The performance is ok for now: On a Core2Duo, I get about 90 MBytes/s AES256 (when using 2 threads). But I may need to improve that in the future - or at least reduce the impact on the CPU. Is it possible to use dedicated AES encryption hardware with Java (using JCE, or maybe a different API)? Would Java take advantage of special CPU features (SSE5?!), if I get a better CPU? Or are there faster JCE providers? (I tried SunJCE and BouncyCastle - no big difference.) Other possiblilities?

  • Get ExternalInterface definitions in Javascript

    - by Jamal Fanaian
    Is there a way to get a list of the exposed functions from a Flash object? For example, you could get a list of all methods in an object by executing: for (var i in object) { if (typeof object[i] == "function") { console.log(i); } } The only issue is that this won't expose any methods registered through the ExternalInterfaces API. I can try and see if the function exists (object['method']) and it tells me it is a function, but I would have to guess every existing method in this manner. NOTE: Obviously, I don't have access to the actionscript.

  • Running external php files or snippets with starting session in Modx?

    - by moogeek
    I want to include an external php script or modx snippet to the index.php but it causes the blank screen instead (and no document parser errors). Probably the problem is that this script i want to include contains starting session functions and set_include_path function that might somehow conflict with Modx parser.. I tried to use the Modx API but it doesn't seem to work. I use Modx 0.9.2.6 yet.. How can I overcome the issue? My script checks the session and database if the user is logged-in on the site (logging system is not modx-based) and then prints the menu depends on the user privileges...

  • Where is the appropriate place to define inflector rules in CakePHP 1.3?

    - by Daniel Wright
    In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else? See also: Configuration: Inflections in the documentation Inflector::rules definition in the API documentation

  • How to use this Color's constructor? Java

    - by MaxMackie
    According to Oracle's site, the class Color has a constructor that accepts a single int value which represents an RGB value. http://download.oracle.com/javase/1.4.2/docs/api/java/awt/Color.html#Color(int) An RGB color is actually three different numbers ranging from 0-255. So combining them together to make one int would look like this: White 255,255,255 White 255255255 Right? So I pass this to the constructor and get a vibrant teal color. What am I doing wrong? What haven't I understood?

  • Cached/offline maps for iPhone?

    - by Konstantin
    I'd like to use use maps in my application, so that there will be as less as possible traffic. Perfect solution would be caching of map slices. I know it's not possible with google maps (license). I took a look on OpenStreetMaps and it seems as good solution. The next: SDK. The only one I've found is from CloudMade. The problem is, I found no related API methods for caching/offline calls. Are there any alternative solutions?

  • Http Geocoder (Google) Accuracy level

    - by sushruth
    I am geocoding a large amount of user entered addresses and interested in the accuracy levels returned. My GOAL is to get the BEST POSSIBLE ACCURACY score for a given address. I call the geocder api following way http://maps.google.com/maps/geo?q={address}&output=csv&sensor=false&key=xx now the accuracy levels returned for same address with/without premise name q = Key Arena, 305 Harrison Street, Seattle, WA 98109 (Accuracy is 5) q = 305 Harrison Street Seattle, WA 98109 (Accuracy is 8) q = Key Arena, Seattle, WA 98109 (Accuracy is 9.) Its obvious from the above that the google servers does not return the best accuracy when street name is appended with premise/venue. the question is :) is there a way to pass the complete address ( with premise name / i.e case 1 ) and get the Max Accuracy. ( or how can tell the google server that the address is passed with premise/building name and street name) ( if you are thinking why not just use case 3, the answer is these are user entered addresses, they could enter "my moms's house" for premise, with accurate street address. in which case i want the accuracy to be 8 not 5)

  • iOS Facebook SDK: FBRequestDelegate only works on AppDelegate??

    - by RMR
    Hi guys, I want to encapsulate all my Facebook interactions within a FacebookFacade class to keep things clean and tidy. I have an instance of the iOS SDK Facebook class within my FacebookFacade. My problem is that when I make a Graph API call within the facade, such as: [self.facebook requestWithGraphPath:@"me" andDelegate:self]; the only method of FBRequestDelegate that gets called is requestLoading: and nothing else. I have tried putting similar code in other places, like in controllers and other models, and there too not all of the FBRequestDelegate methods get called, only requestLoading:. In fact the only way I can get the other FBRequestDelegate methods to be called is to put all my Facebook logic in the AppDelegate and make my AppDelegate the FBRequestDelegate. Why is this the case? Am I missing something here? I definitely do not want to use the AppDelegate as my FBRequestDelegate as I don't want to confuse the purpose of the AppDelegate. Thanks.

  • m2eclipse/svn project with packaging of pom

    - by wuntee
    I have a project with the following layout taac * taac-web * taac-backend-api * taac-scheduler all of this is checked into an SVN repository. When creating a new project in eclipse (originally) I checked out the root taac directory, and it gave me the option to select each of the sub-projects to create new eclipse projects for. I had a problem with svn and had to remove the projects from eclipse, and now when trying to check them out, i no longer get this option. If I select just the sub-projects, then their pom's are invalid (due to not having the parent pom).... Does anyone know how to get that option to select each separate project out?

  • Implementing tracing gestures on iPhone

    - by bmoeskau
    I'd like to create an iPhone app that supports tracing of arbitrary shapes using your finger (with accuracy detection). I have seen references to an Apple sample app called "GestureMatch" that supposedly implemented exactly that, but it was removed from the SDK at some point and I cannot find the source anywhere via Google. Does anyone know of a current official sample that demonstrates tracing like this? Or any solid suggestions on other resources to look at? I've done some iPhone programming, but not really anything with the graphics API's or custom handling of touch gestures, so I'm not sure where to start.
