  • Django version in GAE

    - by Alex
    I'm tring to use Django 1.1 in GAE, But when I uncomment use_library('django', '1.1') in this script import os os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' from google.appengine.dist import use_library #use_library('django', '1.1') # Google App Engine imports. from google.appengine.ext.webapp import util # Force Django to reload its settings. from django.conf import settings settings._target = None import django.core.handlers.wsgi import django.core.signals import django.db import django.dispatch.dispatcher # Unregister the rollback event handler. django.dispatch.dispatcher.disconnect( django.db._rollback_on_exception, django.core.signals.got_request_exception) def main(): # Create a Django application for WSGI. application = django.core.handlers.wsgi.WSGIHandler() # Run the WSGI CGI handler with that application. util.run_wsgi_app(application) if __name__ == "__main__": main() I receives AttributeError: 'module' object has no attribute 'disconnect' What is going on?

  • How to create an "hybrid" usb stick?

    - by rdesign
    Hey guys, I was wondering how to make an hybrid usb stick. That means a usb stick that runs under mac and windows and displays specific content. Example: Plug in on win : index.html opens. Mac os X files are invisible. Plug in on mac: indexMac.html opens. Win files are invisible. I know that every usb stick can be read by both platforms. The Apple Mac os X CD is something which inspired me. thanks a lot.

  • Cleaning up temp folder after long-running subprocess exits

    - by dbr
    I have a Python script (running inside another application) which generates a bunch of temporary images. I then use subprocess to launch an application to view these. When the image-viewing process exists, I want to remove the temporary images. I can't do this from Python, as the Python process may have exited before the subprocess completes. I.e I cannot do the following: p = subprocess.Popen(["imgviewer", "/example/image1.jpg", "/example/image1.jpg"]) p.communicate() os.unlink("/example/image1.jpg") os.unlink("/example/image2.jpg") ..as this blocks the main thread, nor could I check for the pid exiting in a thread etc The only solution I can think of means I have to use shell=True, which I would rather avoid: cmd = ['imgviewer'] cmd.append("/example/image2.jpg") for x in cleanup: cmd.extend(["&&", "rm", x]) cmdstr = " ".join(cmd) subprocess.Popen(cmdstr, shell = True) This works, but is hardly elegant, and will fail with filenames containing spaces etc.. Basically, I have a background subprocess, and want to remove the temp files when it exits, even if the Python process no longer exists.

  • Is there an online user agent database?

    - by Gary Richardson
    How do you parse your user agent strings? I'm looking to get: Browser Browser Version OS OS Version from a user agent string. My app is written in perl and was previously using HTTP::BrowserDetect. It's a bit dated and is no longer maintained. I'm in no way tied to using perl for the actual lookup. I've come to the conclusion that automagic parsing is a lost cause. I was thinking of writing a crud type app to show me a list of unclassified UA's and manually keep them up to date. Does such an resource already exist that I can tap into? It would be awesome if I could make an HTTP call to look up the user agent info. Thanks!

  • how JVM arguments can be passed to apps started through java webstart in macOS.

    - by siva
    Hi, We have a application which is triggered from browser. This application consumes around 800 mb of memory. This works perfectly when invoked from any browsers in windows OS. The same application when triggered from MacOS throws an out of memory exception which occurs when the application is short of memory. Is there any way to increase the memory allocated for apps running in mac os environment. Also please let me know how JVM arguments can be passed to apps started through java webstart in macOS. Thanks in advance Regards, Siva

  • Google Chrome sync: limit for bookmarks & extensions?

    - by Lyubomyr Shaydariv
    Actually, Chrome is my favorite web-browser, and one of its most powerful features is synchronizing the actual data into a Google account. For the last years I gained a lot of bookmarks and from time to time browse the extensions gallery to find new valuable ones. Really, synchronizing between my work and home PC's freed me from manual sync. And for the recent months I experience strange glitches. I guess it may be caused by a lot of stored bookmarks (potentially about 3K [in estimate], but please don't ask why :)) and extensions (about 130 installed but only 10-15 daily used). I can mention the following strange things: Recently added bookmarks sometimes are not synchronized (e.g. I put a bookmark at work, but it's not guaranteed I can see it that evening), despite about:sync indicates a good sync process. Sometimes recently modified bookmarks appear in either (let's call) last at home or last at work bookmark folders. Sometimes bookmarks are not synced at all. (Moreover, Chromium versions may even crash) Extensions are not synced now at all. Perhaps, there's another reason, but Google Mail Checker and Google Reader Notifier do not show indicators of incoming e-mails and news. ... I'm not sure but it looks like I might exceed Chrome internal sync limits... Is it right? Are there any workarounds, or should I make a massive bookmarks/extensions cleanup (I really don't want it :()? I mostly use Google Chrome Canary builds, and the my current one is 12.0.732.0. Thanks in advance. Update #1 (2001-04-19): I removed about 50 extensions that I'm not interested in (or that I consider as trash), and gained pretty some results: The extensions count is below 100 (exactly 97); The chrome://extensions page does not get slow (or even frozen) any more on enabling/disabling/uninstalling extensions; The extensions are seem to be synchronized now again.

  • Bug in the official Android Fragments training sample?

    - by Jeff Axelrod
    It seems to me that there must be a bug in the Android Fragments demo. As background, Fragments are apparently sometimes instantiated by the Android OS and thus need a public no-arg constructor: All subclasses of Fragment must include a public empty constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the empty constructor is not available, a runtime exception will occur in some cases during state restore. But the NewsReader demo from the official Android training on Fragments constructs the HeadlinesFragment class and configures it with setOnHeadlineSelectedListener(this) from NewsReaderActivity.onCreate(). If the Android OS re-instantiates this fragment, the mHeadlineSelectedListener field will be null because HeadlinesFragment doesn't save or restore its state. Is this a bug or am I missing something?

  • How do I program an AVR Raven with Linux or a Mac?

    - by Andrew McGregor
    This tutorial for programming these starts with programming the Ravens and Jackdaw with a Windows box. Can I do those initial steps with avrdude on a Linux or OS X machine instead? If so, how? Is there any risk of bricking the hardware if I just try? I have a USB JTAG ICE MKii clone, which is supposed to work for this. I'm totally new to AVR, but very experienced with C/C++ programming on Linux or OS X, up to and including kernel programming... so any hint at all would be appreciated, I can read man pages, but only if I know what I'm looking for.

  • Automated Scanning for Corrupted Archive Files

    - by Synetech inc.
    Hi, I have all kinds of files that I have downloaded from everywhere over the years scattered around my hard drives. I’m in the process of trying to organize them all and have run into a problem. Sometimes a file was not downloaded correctly (this was a big issue when Chromium first came out) and is thus corrupt. For media files, this is relatively simple to determine (it requires actually opening and examining the file). For executables or other binaries, it is relatively difficult (executables may or may not crash, other binaries could be completely unknown). Archive files (eg zip, rar, 7z, exe, ace, etc.) however should be pretty simple, they have a built-in corruption detection facility. My problem now is that I really don’t want to open and test each and every single archived file throughout my drive; that would be a nightmare. I’m looking for a utility that can automate the process. Is there a program that can scan archive files on a drive and list the ones that are corrupt? Thanks a lot.

  • How to do a sample rate conversion in Windows (and OSX)

    - by Paperflyer
    I am about to write an audio file converter for my side job at the university. As part of this I would need sample rate conversion. However, my professor said that it would be pretty hard to write a sample rate converter that was both of good quality and fast. On my research on the subject, I found some functions in the OSX CoreAudio-framework, that could do a sample rate conversion (AudioConverter.h). After all, an OS has to have some facilities to do that for its own audio stack. Do you know a similar method for C/C++ and Windows, that are either part of the OS or open source? I am pretty sure that this function exists within DirectX Audio (XAudio2?), but I seem to be unable to find a reference to it in the MSDN library.

  • appcfg.py upload_data entity kind problem

    - by Dingo
    Hi, I am developing application on app-engine-path and I would like to upload some data to datastore. For example I have a model models/places.py: class Place(db.Model): name = db.StringProperty() longitude = db.FloatProperty() latitude = db.FloatProperty() If I save this in view, kind() of this entity is "models_place".

  • ListView adapter data change without ListView being notified

    - by brockoli
    I've written a ListActivity that has a custom list adapter. The list is being updated from a ContentProvider when onCreate is run. I also have a service that gets started when I run the app and it first updates the ContentProvider, then sends a Broadcast that the content has been updated. My ListActivity recieves the broadcast and tries to update my ListView. My problem is, I'm getting intermittent errors about the ListView adapter data changing without the ListView being notified. I call the notifyDataSetChanged() method on my list adapter right after I update it. What it seems like is happening is the list is still in the process of being updated after first call in onCreate when it recieves the broadcast from the service to update, so it tries to update my ListView before it's finished updating from it's first run. Does this make sense? Here is some of my code. NOTE: The service is working properly, it gets new data and updates my ContentProvider, and I do get the broadcast in my activity when it is updated. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ctx = this; getPrefs(); setContentView(R.layout.main); // Setup preference listener preferences = PreferenceManager.getDefaultSharedPreferences(this); preferences.registerOnSharedPreferenceChangeListener(listener); // Setup report list adapter ListView nzbLv = (ListView) findViewById(R.id.report_list); nzbla = new NZBReportListAdaptor(ctx); getReports(); nzbla.setListItems(report_list); nzbLv.setAdapter(nzbla); // Broadcast receiver to get notification from NZBService to update ReportList registerReceiver(receiver, new IntentFilter(NZBService.BROADCAST_ACTION)); startService(new Intent(ctx, NZBService.class)); } @Override public void onResume() { super.onResume(); timerHandler.resume(); new updateSabQueue().execute(); //updateList(); } @Override public void onPause() { super.onPause(); timerHandler.pause(); unregisterReceiver(receiver); } private BroadcastReceiver receiver = new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { Toast.makeText(ctx, "NZBService broadcast recieved", Toast.LENGTH_SHORT).show(); updateReportList(); } }; private void updateReportList() { new updateReportList().execute(); } private class updateReportList extends AsyncTask<Void, Void, Boolean> { /* (non-Javadoc) * @see android.os.AsyncTask#onPreExecute() * Show progress dialog */ protected void onPreExecute() { } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) * Get new articles from the internet */ protected Boolean doInBackground(Void...unused) { getReports(); return true; } /** * On post execute. * Close the progress dialog */ @Override protected void onPostExecute(Boolean updated) { if (updated) { Log.d(TAG, "NZB report list adapter updated"); synchronized(this) { nzbla.setListItems(report_list); } Log.d(TAG, "NZB report list notified of change"); nzbla.notifyDataSetChanged(); } } } Now that this question is answered, I will post my updated code in an effort to help others who might come across it. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ctx = this; getPrefs(); setContentView(R.layout.main); // Setup preference listener preferences = PreferenceManager.getDefaultSharedPreferences(this); preferences.registerOnSharedPreferenceChangeListener(listener); // Setup report list adapter ListView nzbLv = (ListView) findViewById(R.id.report_list); nzbla = new NZBReportListAdaptor(ctx); report_list.addAll(getReports()); nzbla.setListItems(report_list); nzbLv.setAdapter(nzbla); // Broadcast receiver to get notification from NZBService to update ReportList registerReceiver(receiver, new IntentFilter(NZBService.BROADCAST_ACTION)); startService(new Intent(ctx, NZBService.class)); } private class updateReportList extends AsyncTask<Void, Void, ArrayList<Report>> { /* (non-Javadoc) * @see android.os.AsyncTask#onPreExecute() * Show progress dialog */ protected void onPreExecute() { } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) * Get new articles from the internet */ protected ArrayList<Report> doInBackground(Void...unused) { return getReports(); } /** * On post execute. * Close the progress dialog */ @Override protected void onPostExecute(ArrayList<Report> updated) { nzbla.setListItems(updated); nzbla.notifyDataSetChanged(); } } private ArrayList<Report> getReports() { ArrayList<Report> reports = new ArrayList<Report>(); ContentResolver r = getContentResolver(); Cursor c = r.query(NZBReportProvider.CONTENT_URI, null, null, null, NZBReportProvider.ARTICLE_KEY_ROWID + " DESC"); startManagingCursor(c); Log.d(TAG, "NZBReport cursor.getCount=" + c.getCount()); int title = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_TITLE); int desc = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_DESCRIPTION); int cat = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_CAT); int size = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_SIZE); int link = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_LINK); int catid = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_CATID); int date = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_DATE_ADDED); int group = c.getColumnIndex(NZBReportProvider.ARTICLE_KEY_GROUP); if (c.getCount() > 0) { c.moveToFirst(); do { URL url = null; try { url = new URL(c.getString(link)); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } reports.add(new Report(c.getString(title), url, c.getString(desc), c.getString(cat), c.getString(date), c.getString(size), c.getInt(catid), c.getString(group))); } while (c.moveToNext()); } return reports; }

  • iTunes Apple Events API

    - by jldupont
    I'd like to control iTunes through Objective-C ( I just can't get Python appscript installed correctly on my OS/X 10.6.3 system ... that would have been my first choice ). From what I gather, the IPC on Cocoa is based on Apple Events : is there either: Online documentation on iTunes / Apple Events API ? Instrospection mechanism to get to iTunes API? I know about Applescript Editor / Open Dictionary functionality but I can't figure out how to translate the information I see into IPC calls. Note: I have already tried working out a solution through PyObjC but the main function I am after is track searching which I can't figure out. Disclaimer: OS/X super-newbie here.

  • iPhone application launch time guidelines

    - by Alexander Gladysh
    Please point me to the iPhone application launch time guidelines. I see that there is a hard limit of ~24 seconds. OS kills application if it did not started in that time with the message: com.bundle.id failed to launch in time There is also a QA article on this. (24 seconds is the time until OS on my phone kills the app.) But I think that there should be a shorter soft limit somewhere in the docs. However, my google-fu failed me and I was not able to find it. Any help?

  • JNI call to Intel or PPC arch jnilib function differs

    - by vinzenzweber
    I am making a call from within Java to a jnilib function and get different logs on PPC and Intel. My function definitions are as follows: private native int initHandler(long vendorID, long productID); JNIEXPORT jint JNICALL Java_com_sue_protocol_SerialPortObserverThread_initHandler( JNIEnv *env, jobject obj, jlong usbVendor, jlong usbProduct) When initHandler() is called, the logs differ on the platforms: Mac OS X/10.5.8/ppc, Java 1.5.0_22 Looking for devices matching vendor ID=0 and product ID=7982. Mac OS X/10.6.3/x86_64, Java 1.6.0_17 Looking for devices matching vendor ID=7982 and product ID=10. The sample source for this project can be found on http://github.com/vinzenzweber/USBEventHandler What do I need to do to get the JNI call right on ALL platforms?

  • fd.seek() IOError: [Errno 22] Invalid argument

    - by Julian Kessel
    My Python Interpreter (v2.6.5) raises the above error in the following codepart: fd = open("some_filename", "r") fd.seek(-2, os.SEEK_END) #same happens if you exchange the second arg. w/ 2 data=fd.read(2); last call is fd.seek() Traceback (most recent call last): File "bot.py", line 250, in <module> fd.seek(iterator, os.SEEK_END); IOError: [Errno 22] Invalid argument The strange thing with this is that the exception occurs just when executing my entire code, not if only the specific part with the file opening. At the runtime of this part of code, the opened file definitely exists, disk is not full, the variable "iterator" contains a correct value like in the first codeblock. What could be my mistake? Thanks in advance

  • Fairness: Where can it be better handled?

    - by Srinivas Nayak
    Hi, I would like to share one of my practical experience with multiprogramming here. Yesterday I had written a multiprogram. Modifications to sharable resources were put under critical sections protected by P(mutex) and V(mutex) and those critical section code were put in a common library. The library will be used by concurrent applications (of my own). I had three applications that will use the common code from library and do their stuff independently. my library --------- work_on_shared_resource { P(mutex) get_shared_resource work_with_it V(mutex) } --------- my application ----------- application1 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application2 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application3 { *[ work_on_shared_resource ] } *[...] denote a loop. ------------ I had to run the applications on Linux OS. I had a thought in my mind, hanging over years, that, OS shall schedule all the processes running under him with all fairness. In other words, it will give all the processes, their pie of resource-usage equally well. When first two applications were put to work, they run perfectly well without deadlock. But when the third application started running, always the third one got the resources, but since it is not doing anything in its non-critical region, it gets the shared resource more often when other tasks are doing something else. So the other two applications were found almost totally halted. When the third application got terminated forcefully, the previous two applications resumed their work as before. I think, this is a case of starvation, first two applications had to starve. Now how can we ensure fairness? Now I started believing that OS scheduler is innocent and blind. It depends upon who won the race; he got the largest pie of CPU and resource. Shall we attempt to ensure fairness of resource users in the critical-section code in library? Or shall we leave it up to the applications to ensure fairness by being liberal, not greedy? To my knowledge, adding code to ensure fairness to the common library shall be an overwhelming task. On the other hand, believing on the applications will also never ensure 100% fairness. The application which does a very little task after working with shared resources shall win the race where as the application which does heavy processing after their work with shared resources shall always starve. What is the best practice in this case? Where we ensure fairness and how? Sincerely, Srinivas Nayak

  • Writing temporary data from R

    - by Shane
    I want to write some temporary data to disk in an R package, and I want to be sure that it can run on every OS without assuming the user has admin rights. Is there an existing R function that can provide a path to a temporary directory on all major OS's? Or a way to reference a user's home directory? Otherwise, I was thinking of trying this: Sys.getenv("temp") I presume that I can't expect people to have write access to their R locations, otherwise I could reference a path within the package directory: .find.package("package.name").

  • MSMQ.MSMQQueueInfo PathName Not Accepted

    - by user357596
    I am using MSMQ.MSMQQueueInfo with jscript on Windows 7 (the latest MSMQ version). This is being run on a domain joined computer. For some reason unknown to me, it just will not accept the PathName I give it (which is in an acceptable format). Here is the code: var qi = new ActiveXObject ("MSMQ.MSMQQueueInfo"); qi.PathName = "FormatName:Direct=OS:mycomputer\\Private$\\myqueue"; I know this PathName works, because I use the exact same path in c#, and that works: queue = new MessageQueue("FormatName:DIRECT=OS:" + contollerName + "\\Private$\\" + queueName); When the code "qi.Open()" in the jscript code attempts to execute, it returns this error message: The queue path name specified is invalid. Has anyone else run into this? Ideas? Comments? Suggestions? Thank you in advance!

  • PIL saves image colour wrong

    - by Tom Viner
    I have an image. I want to resize it using PIL, but it come out like this. Even without a resize it still messes up the colour. Minimal code: from PIL import Image import os import urllib import webbrowser orig_url = 'http://mercedesclub.org.uk/images/stackoverflow-question/least-popular-colours-_-500-x-500.jpg' temp_fn, _ = urllib.urlretrieve(orig_url) im = Image.open(temp_fn) fn = os.tempnam() + '.jpg' im.save(fn) webbrowser.open(fn) I've tried Image.open(temp_fn).convert(format) with 'RGB', 'CMYK' and 'L' as formats, but still get weirdly coloured or grey results. When I load the image from my hard drive and I can see: >>>im.info {'adobe': 100, 'progression': 1, 'exif': 'Exif\x00\x00MM\x00*...\x7f\xff\xd9', 'adobe_transform': 100} >>>im.format 'JPEG' >>>im.mode 'CMYK' >>> im._getexif() {40961: 65535, 40962: 500, 40963: 500, 296: 2, 34665: 164, 274: 1, 305: 'Adobe Photoshop CS Macintosh', 306: '2010:02:26 12:46:54', 282: (300, 1), 283: (300, 1)} Thanks and let me know if you need any more data.
