  • Enabling mod_wsgi in Apache for a Django app on Gentoo

    - by hobbes3
    I installed Apache, Django, and mod_wsgi on Gentoo using emerge (on Amazon EC2). I know that the mod_wsgi is configured in /etc/apache2/modules.d/70_mod_wsgi.conf: <IfDefine WSGI> LoadModule wsgi_module modules/mod_wsgi.so </IfDefine> # vim: ts=4 filetype=apache So in my /etc/conf.d/apache I added the WSGI module: APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D WSGI" But when I try to list the loaded module, mod_wsgi isn't listed. root ~ # apache2 -M | grep wsgi Syntax OK I also know that mod_wsgi isn't loading properly because the Apache configuration file doesn't recognize WSGIScriptAlias. By the way for Django to work I need to include a custom Apache configuration file. Where should I insert the line below? Include "/var/www/localhost/htdocs/mysite/apache/apache_django_wsgi.conf" I currently have that in the httpd.conf file but I feel like that file will get reseted whenever I upgrade Gentoo or related package. EDIT: it seems the mod_wsgi file is located in /usr/lib64/apache2/modules/mod_wsgi.so. Here is my detailed Apache settings: root@ip-99-99-99-99 /usr/portage/eclass # apache2 -V Server version: Apache/2.2.21 (Unix) Server built: Mar 7 2012 06:52:30 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.5, APR-Util 1.3.12 Compiled using: APR 1.4.5, APR-Util 1.3.12 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/usr" -D SUEXEC_BIN="/usr/sbin/suexec" -D DEFAULT_PIDLOG="/var/run/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types" -D SERVER_CONFIG_FILE="/etc/apache2/httpd.conf"

  • Which CMS or blogging engine supports multiple sites ?

    - by Lamnk
    Dont know if SO is the appropriate place to ask this question, but anyway ... I have some sites running Wordpress and maintaining/managing them is a pain. Is there any CMS or blogging platform out there that support multiple sites/blogs in one codebase ? I know there are some hacks for Wordpress but they are quite ugly and do not scale (i need 100-1000 blogs supported). WPMU AFAIK run with subdomains only. Thanks in advance.

  • DCVS + hosting for a startup commercial multiplatform phone app

    - by AG
    I'm in lean startup mode, working on a simple phone app that will be published initially as a iThingy app and an Android app with, possibly, Blackberry and Symbian versions to follow. I'm about to go from no repository to needing a central repository that up to 4 very part-time resources will be sharing. Two of us have no version control background, one has used Subversion, and I've used most of the major centralized VCS systems. I'm not going to be pushing the technical limitations of any VCS for a long time; I'm sure that any of the major systems would work fine. And the hosting accounts I've looked at seem reasonable. So I'm really focussed on minimizing the downside risks. That is, I'd like to find a stable setup that is easy to learn in general, easy to use from Windows/Eclipse, and won't paint me into any obvious corners for the next 12 months or so. A quick search of the web had led me to consider the following pairs of DVCS and hosting service, with what I think I'm hearing as their strengths and weaknesses (for my purposes): Bazaar/Launchpad -- My initial choice since I need to get more familiar with this pair for the Google Summer of Code mentoring I'm doing. But, whatever the technical merits, a non-starter for me because they are purely open source, no private repositories plans to purchase that I can see. Git/GitHub -- Git: Fast, light, ultimately flexible, but relatively less Windows friendly, Eclipse plugin (eGit) available but relatively young, GitHub: widely used, pricing is fine Mercurial/BitBucket -- Mercurial: a little less flexible, a little more Windows friendly, Eclipse plugin seems a bit more mature, BitBucket: widely used, pricing is fine, includes a wiki and an issue tracker that we might be able to use instead of something like BaseCamp, at least for a while. Mercurial/BitBucket seem like the winning pair so far for my particular situation; at least two of us are definitely going to be working mostly from Eclipse on Windows and reducing my own learning curve is a priority. ;-) But I have two specific questions: 1) Am I wrong about Bazaar/Launchpad and is there a viable, secure way to use them for proprietary code? 2) Any reason to think that the Mecurial/Bitbucket pair will end up being a headache for my Mac developer, soon, or for Blackberry or Symbian developers a little later? ag

  • Core-Data Can't pass managedObjectContext from app delegate to view controller

    - by yahuie
    I'm making a core-data application that is view based. I can create the managedObjectContext and 'use' it in the app delegate, but can not pass it to the mainviewcontroller. Probably something simple, but I can't find the problem after looking for quite a while. The managedObjectModel is nil in the mainviewcontroller.

  • VNC from Windows to OS X Lion: App stuck in fullscreen mode

    - by Jonny
    I'm connecting to a remote Mac through a Windows. ahh it gets more complicated than that. I'm sitting by my iMac. I use Virtual Box in it to launch Windows 7. In it I have a VPN connection to a remote Windows network, which allows me to use Remote Desktop to one of the Windows (Vista!) boxes over there. From that Vista box I VNC into a Mac OS X Lion. (Don't ask me why, but that Mac doesn't have a public ip which prevents me from accessing it in the first place.) So: OSXLion - (virtual)Windows7 - Windows Vista - OSX Lion That last Mac was recently upgraded from Snow Leopard. Now with Lion, sometimes apps run in fullscreen. Somehow I can't get out of that fullscreen. Normally you'd move the mouse pointer to the top of screen and a menu list bar drops down allowing you to reach the fullscreen button top right. Now, in my current setup that menu list bar never drops down on the remote Mac at the end of the line. Any ideas?

  • Delete files from blobstore using file serving URL

    - by Arturo
    In my app (GWT on GAE) we are storing on our database the serving URL that is stored on blobstore. When user selects one of these files and clicks "delete", we need to delete the file from blobstore. This is our code, but it is not deleting the file at all: public void remove(String fileURL) { BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); String key = getBlobKeyFromURL(box.getImageURL()); BlobKey blobKey = new BlobKey(key); blobstoreService.delete(blobKey); } Where fileURL looks like this: http://lh6.ggpht.com/d5VC0ywISACeJRiC3zkzaZug-tPsaI_LGt93-e_ATGTCwnGLao4yTWjLVppQ And getBlobKeyFromURL() would return what is after the last "/", in this example: d5VC0ywISACeJRiC3zkzaZug-tPsaI_LGt93-e_ATGTCwnGLao4yTWjLVppQ Could you please advice? Thanks

  • Axis Rotation Question using sio2 game engine

    - by Leo
    By using left hand rule, I rotate one object left and right using x axis, and rotate up/down using y axis. After first object is rotated to the right, the up/down rotation should be using z axis. However, when I try to rotate using z axis, after the first rotation, it has the same effect when I rotate using y axis. Anyone has any ideas? Thanks

  • Pin same app multiple times in Windows 7

    - by Mr. Shiny and New
    I use some programs with command line arguments and like to have shortcuts for launching those programs with those arguments. For example, I keep several Firefox profiles around and like to specify the profile name on the command line. Similarly I have several Eclipse shortcuts with a command line argument specifying the workspace to open. I would like to be able to pin these shortcuts to the start menu or taskbar in Windows 7. The problem I have is that once I've pinned one of these, no other shortcuts which launch the same exe can be launched. I'm also open to suggestions such as a suitable desktop gadget which can contain a bunch of arbitrary shortcuts, yet remain in a fixed position on my desktop somewhere, or some way of adding a secondary taskbar (this was possible in XP).

  • memory usage in C# (.NET) app is very high, until I call System.GC.Collect()

    - by Chris Gray
    I've written an app that spins a few threads each of which read several MB of memory. Each thread then connects to the Internet and uploads the data. this occurs thousands of times and each upload takes some time I'm seeing a situation where (verified with windbg/sos and !dumpheap) that the Byte[] are not getting collected automatically, causing 100/150MB of memory to be reported in task manager if I call System.GC.Collect() i'm seeing a huge drop in memory, a drop of over 100MB I dont like calling System.GC.Collect() and my PC has tons of free memory. however if anyone looks at TaskManager they're going to be concerned, thinking my app is leaking horribly. tips?

  • Using powershell call native command-line app and capture STDERR

    - by crtracy
    I'm using a port of a cygwin tool on Windows which writes normal status messages to STRERR. This produces ugly output when run from PowerShell: PS> dos2unix.exe -n StartApp.sh StartApp_fixed.sh dos2unix.exe : dos2unix: converting file StartEC3.sh to file StartEC3_fixed.sh in UNIX format ... At line:1 char:13 + dos2unix.exe <<<< -n StartApp.sh StartApp_fixed.sh + CategoryInfo : NotSpecified: (dos2unix: conve...UNIX format ...:String) [], RemoteException + FullyQualifiedErrorId : NativeCommandError Is there a better way? P.S. I intend to post one solution I've found and compare it to answers from others.

  • Add single sign-on into existing web app

    - by EvilDr
    Apologies if this isn't the best site, I've search for an answer but can't find anything quite right. I don't actually now the correct terminology I should be using here, so any pointers will be appreciated. I have a web application that accessed by many different users across different organisations. Access is provided by each user having a unique username/password which is stored in SQL (database fields are customerID, userID, username). Some organisations are now asking if we can change this to allow "Active Directory single sign-on" so that users don't need to remember yet another set of login details. From research I can see how this is achieved using OpenAuth and Google (etc), but I know hardly anything about AD and can't find much information on this (again I'm sure it helps when you know the terminology). Is this request even possible to achieve, given that most users will be from different (and unrelated) organisations? I saw on a Microsoft Build video not long ago that there is some kind of replication service for AD to allow Cloud authentication. Is this what I should be aiming for?

  • App not shown in 2.1 Market

    - by an
    I published several free and paid app in the Market. I recently get several complains from customers about not finding my app in the 2.1 Market. Even if they have bought them before, they can't find it in the market or their download list after updating to 2.1. Can anyone tell me what the problem is? My apps only require minimal SDK 3.. Thanks a lot!! Update: It looks like that they are not shown because they have copy protection enabled. Is this a bug in the Market?

  • Hiding monitor from windows, working with it from my app only [closed]

    - by Mikhail
    I need to use a monitor as a "private" device for my special application, I want to use it as a flashlight of a sort and draw special patterns on it in full screen. I don't want this monitor to be recognized by OS (Windows 7) as a monitor. I.e. user should not be able to move mouse to that monitor, or change its resolution, or run screensaver on it or whatever. But I want to be able to interact with it from my application. Monitor is plugged using an HDMI cable to a video card (most probably nVidia). What is the simplest way to do this? All solutions are appreciated, including purchasing additional adapters or simple video cards, or any other special devices.

  • Optimizing tasks to reduce CPU in a trading application

    - by Joel
    Hello, I have designed a trading application that handles customers stocks investment portfolio. I am using two datastore kinds: Stocks - Contains unique stock name and its daily percent change. UserTransactions - Contains information regarding a specific purchase of a stock made by a user : the value of the purchase along with a reference to Stock for the current purchase. db.Model python modules: class Stocks (db.Model): stockname = db.StringProperty(multiline=True) dailyPercentChange=db.FloatProperty(default=1.0) class UserTransactions (db.Model): buyer = db.UserProperty() value=db.FloatProperty() stockref = db.ReferenceProperty(Stocks) Once an hour I need to update the database: update the daily percent change in Stocks and then update the value of all entities in UserTransactions that refer to that stock. The following python module iterates over all the stocks, update the dailyPercentChange property, and invoke a task to go over all UserTransactions entities which refer to the stock and update their value: Stocks.py # Iterate over all stocks in datastore for stock in Stocks.all(): # update daily percent change in datastore db.run_in_transaction(updateStockTxn, stock.key()) # create a task to update all user transactions entities referring to this stock taskqueue.add(url='/task', params={'stock_key': str(stock.key(), 'value' : self.request.get ('some_val_for_stock') }) def updateStockTxn(stock_key): #fetch the stock again - necessary to avoid concurrency updates stock = db.get(stock_key) stock.dailyPercentChange= data.get('some_val_for_stock') # I get this value from outside ... some more calculations here ... stock.put() Task.py (/task) # Amount of transaction per task amountPerCall=10 stock=db.get(self.request.get("stock_key")) # Get all user transactions which point to current stock user_transaction_query=stock.usertransactions_set cursor=self.request.get("cursor") if cursor: user_transaction_query.with_cursor(cursor) # Spawn another task if more than 10 transactions are in datastore transactions = user_transaction_query.fetch(amountPerCall) if len(transactions)==amountPerCall: taskqueue.add(url='/task', params={'stock_key': str(stock.key(), 'value' : self.request.get ('some_val_for_stock'), 'cursor': user_transaction_query.cursor() }) # Iterate over all transaction pointing to stock and update their value for transaction in transactions: db.run_in_transaction(updateUserTransactionTxn, transaction.key()) def updateUserTransactionTxn(transaction_key): #fetch the transaction again - necessary to avoid concurrency updates transaction = db.get(transaction_key) transaction.value= transaction.value* self.request.get ('some_val_for_stock') db.put(transaction) The problem: Currently the system works great, but the problem is that it is not scaling well… I have around 100 Stocks with 300 User Transactions, and I run the update every hour. In the dashboard, I see that the task.py takes around 65% of the CPU (Stock.py takes around 20%-30%) and I am using almost all of the 6.5 free CPU hours given to me by app engine. I have no problem to enable billing and pay for additional CPU, but the problem is the scaling of the system… Using 6.5 CPU hours for 100 stocks is very poor. I was wondering, given the requirements of the system as mentioned above, if there is a better and more efficient implementation (or just a small change that can help with the current implemntation) than the one presented here. Thanks!! Joel

  • Iphone & Web App synch

    - by Jack Welsh
    I am trying to build an Iphone App client for our CRM solution so our sales people would be able to access the information available in our CRM through an Iphone App. I am trying to find out what is the recommended approach to architect the application when it comes to the database. I am not sure where should the data reside, should I save a subset of the data on the iPhone, or should I just rely on webservices and pull the information I need from the database whenever I need it. Also, is there any best practices or frameworks to build such applications on the Iphone.

  • facebook app using fbml displays nothing

    - by fusion
    i've made an app in php and html and trying to integrate it with fb. the app on my website is using jquery, but knowing that fbml doesn't support jquery, i've tried to instead use fbjqry. this doesn't work either. i'm not sure where i'm going wrong. /////////////// index.php: <?php // Copyright 2007 Facebook Corp.

  • MS Office & WebDAV Server Engine for .NET

    On this website,http://www.webdavsystem.com/server/documentation/ms_office_read_only, it states that in order to open a writable version of a MS Office doc this condition has to be met: Your WebDAV server must be configured on site root. Is this still true? Because I tried the SqlStorage sample and it works fine. I deployed the application on IIS 7, under <server>/TestWebDav and MS Office 2010 opened the documents in the sample just fine. Thanks
