We're using the facebook SDK to install multiple facebook applications simultaneously, but sometimes not all apps are installed.
It appears there is some limitation or bug regarding the number of facebook applications we can install at a time (on facebook's side).
For the time being we've implemented a workaround, which includes waiting for a few seconds between each app installation, but obviously that's not a solution and it's also not working properly.
Has anyone encountered such a problem? What did you do with it?
Thanks!
Relevant Installation Code:

So I am building a simple crud webapp using django on frontend I am using typescript no frontend frameworks or libraries whatsoever. And currently I am doing this on windows 10 but if I switch to linux Ubuntu completely and continue building this on linux, Will it have any problems when building it even if I use the same version of django and python that was on windows 10.
I am asking this because of problems in past that it works on one machine but not on different so then vm's and container technologies came out.
Appreciate any help.
No, I don't think you will encounter any issues doing so. Most of the developers develop Django applications on Windows machines and deploy them to Linux servers. so you will find plenty of documentation to get it running on Linux.
I am implementing push notifications from my server to the users who are subscribed to my server.
Right now sending the push notifications to Firefox users works like a charm. However, on Chrome I get an Unauthorized Registration error. I am using Django as a backend.
In this image are the relevant parts of the error and my code (email edited), aswell as the subscription. If any more information is needed please let me know.
Does anyone know why I can't send push notifications on Chrome?
And I am using this library.
In the murky depths of Google and Github I have found the answer. If you install pywebpush it installs v1.2.2 of py-vapid, which had a bug in it. Overwriting this package with
pip install py-vapid --upgrade
installs the patched version 1.2.3 (released only 5 days ago as of this post), fixes the Unauthorized bug I was having.
I've just pushed pywebpush 1.0.2 which includes py-vapid 1.2.3. Sorry for the delay, but it was unavoidable.
Please don't be afraid to file issues against the package. I do try to respond fairly quickly and it helps out everyone.
I am currently developing an instant messaging feature for my apps (ideally cross platform mobile app/web app), and I am out of ideas to fix my issue.
So far, I have been able to make everything work locally, using a Node.js server with socket.io, django, and redis, following what most tutorials online suggest.
The step I am now at consists in putting all that in the cloud using amazon AWS. My Django server is up and running, I created a new separate Node.js server, and I am using Elasticache to handle the Redis part. I launch the different parts, and no error shows up.
However, whenever I try using my messaging feature on the web, I keep getting an error 500:
handshake error
I then used the console to check the request header, and I observed that the cookies are not in there, contrary to when I am on localhost. I know it is necessary to authorize the handshake, so I guess that's where my error is coming from..
Furthermore, I have also checked that the cookies do exist, they are just not set in the request header.
My question is then: How can I make sure Django or socket client (not sure who's responsible here..) puts the cookies in the header??
One of my ideas was that maybe I am supposed to put everything on the same server, with different ports, instead of 2 separate servers? Documentation on that specific architecture problem is surprisingly scarce, compared to the number of tutorials describing how to make it work on local.
I hope I described the problem accurately enough! :)
Important note: I am using socket.io v0.9.1-1, only one compatible with a titanium mobile app.
Thank you for any help!
All right, so I've made some progress.
The cookie problem came from the fact I was making cross-domain request, adding a few lines enabled CORS, which didn't solve the cookie issue, but allowed me to communicate between servers (basically I set the headers of the response using express. I then passed necessary data in the query, even if not the most secure way to do it, I'm just building an MVP, and it's enough for now.
I haven't been able to make the chat work from my Titanium mobile app, but since I can use a webview to handle it, I will be fine.
Hopefully that will help someone.. If anyone needs me to post some code snippets I will gladly do so upon request!
Cheers
Recently I have been experimenting with Firebreath and developed a plugin in order to showcase my c++ projects on my portfolio website. I would like to make it easy for users to look at the projects without downloading files if they are new on my website.
The only issue I have at this point is that when users visit my page, they will receive a message indicating the plugin is missing. I would like to have an option for the users to automatically install my plugin without having to manually download and run it.
The plugin is mainly targetted at Windows users, since the applications are as well. I intend to support Google Chrome, Firefox, Internet Explorer. Currently I am using a MSI installer to install the plugin.
I have found a question similar to this, but I still needed to save the MSI installer and run it.
My question is: What would be the best way to implement this?
There isn't any way to "automatically" do what you want to do. The closest that I have heard of would be to use a java applet that would download and install the plugin for them. This can be pretty reliable on Mac but far less reliable on windows (for a number of reasons, among which the fact that many windows users don't have java installed and that Chrome blocks java applets by default without intervention by the user).
Other options include:
Creating a CAB file installer (only works on IE)
Creating a XPI firefox extension that packages the plugin (requires restarting the browser, only works on firefox)
Creating a CRX chrome extension that packages the plugin (only works on Chrome)
Microsoft ClickOnce used to work pretty well for one click installs of MSI files from a web page, but recently I think it doesn't work on many (if any) browsers; haven't seen it used in awhile, anyway.
There is no "automatic" way to install plugins; that would be considered a severe security issue. This is probably the #1 reason that plugins are as uncommon as they are.
do what adobe does,
create a tiny activeX application downloader, sign the activeX from with cheap SSL
when a user, enters your site, he will automatically be downloading this tiny ActiveX, after installation complete, inside the tiny ActiveX, have some type of batch script to download the EXE from remote server and silently install it.
adobe does this, on every reboot in boot.ini or startups
very easy
I am given a responsibility in my project to develop a Equipment tracking tool with following requirements
New Equipment can be added by admin to a particular user
Once equipment is assigned to a person he will a request to accept the request so he will be responsible
User can transfer his equipment to other users.
At the same time Admin should be sent a mail or message whenever there is a change in status.
It should be deployed locally on a PC( So it is not actually a web app) that is connected to network which can be accessed by everyone
I thought I can use Django for this( I am new to it ), but I do not know much about deployment on a local PC , How can I do this, or is there any better Idea for this?
It still sounds like you want a web app, you just won't be deploying it on a traditional web server. One thing to note, client versions of Windows (XP, Vista) will limit you to 10 incoming connections per computer.
You'll want to follow these instructions on how to install Django. If you haven't installed python yet, I'll recommend that you install version 2.5, since that will include sqlite, an embedded database that makes it very easy to get started developing with Django. Django includes its own development web server, which you will come across naturally as you go through the tutorial.
Start by installing and then jump right into the tutorial. Your deployment options will be much easier to understand once you're comfortable with developing in Django.
Try http://docs.djangoproject.com/en/dev/howto/deployment/#howto-deployment-index
and if you should deploy using IIS then try http://code.djangoproject.com/wiki/DjangoOnWindowsWithIISAndSQLServer
