kandi X-RAY | redbird Summary
The HTTPS proxy supports virtual hosts by using SNI (which most modern browsers support: IE7 and above). The proxying is performed by hostname, so you must use the same SSL certificates for a given hostname independently of its paths.

QUESTION
I'm trying to get two animations to show at the same time. The application builds successfully but crashes in the emulator.
I have created an Anim class in a thread that handles the Animations in a while loop. I think there is a problem with my draw method but I cant seem to figure it out.
I appreciate any help on this, thank you
Error Log ...ANSWER
Answered 2021-Mar-20 at 06:13Because accessing a SurfaceView (with Canvas) is exclusive, you cannot draw simultaneously to it.
QUESTION
I have a yaml file that I converted into a nested dictionary variable. The dictionary is passed into a python function (render_yaml_dict()
) that takes the nested dictionary with unformatted values and returns the nested dictionary with formatted values. I'm using recursion to parse through the nested dictionary and jinja formatting to format string values with sibling values.
Here's the function's input nested dictionary:

QUESTION
Bad(?) news "SSL For Free is joining ZeroSSL". Since their news I renewed my certificates and TLS stopped working. Used to work fine.
With new certificates I get error "You may need to install an Intermediate/chain certificate to link it to a trusted root certificate" from https://www.sslshopper.com/ssl-checker.html and this error "TLS Certificate is not trusted" from https://www.digicert.com/help.
Browsers are smart enough to mask the problem but my Android app uses an API and it stopped working.
Anyone else getting TLS problems since ZeroSSL got involved?
I'm using redbirdjs on nodejs which is awesome since its so simple (two domains, same server), but Zero provides no installation instructions for my setup. (My domains are small in traffic so using the fastest webservers etc. isn't an issue).
Zero took away the 2 domains in one cert option (gee thanks) so my updated script looks like:
...ANSWER
Answered 2020-Jun-12 at 15:22Well, I got it working. I used https://whatsmychaincert.com, which I think just literally joins a couple files together. Either way for redbird fans (like me) here is the script for multiple domains on the same server.
QUESTION
I want to implement the same functionality Intercom provides to their clients; they allow the implementation of Custom Domains for Articles. I'm not quite sure how they go about their method of implementation, or what they're doing behind the scenes, exactly.
Take the following scenario; a client (company NorthWind), has a subdomain on my company's website (northwind.example.com).
The following is to occur:
- If a user types
northwind.example.com
, they go tonorthwind.example.com
andnorthwind.example.com
appears in the url bar. - If a user types
example.northwind.com
, they go tonorthwind.example.com
andexample.northwind.com
appears in the url bar.
The difference between the way Intercom implements it and the way I wish to implement it is that I'm using a subdomain, not a directory, as seen in Intercom's help article linked above.
Considering my website runs on Nginx, NodeJS, and MongoDB, here's what I came up with so far:
- Client registers a CName record on their domain provider to point to their page on my website.
- Client provides the CName record they used to my website (register it through a form).
- I save a record in MongoDB for the company and their custom domain.
- I register, or re-register, the reverse proxies of my website, using redbird to allow the redirection to go through.
I've already looked into Redirect Web Page to Another Site Without Changing URL and Does a Cname Change the URL that the Browser Displays.
Am I on the right path, or is there a better method?
...ANSWER
Answered 2020-Jun-09 at 07:14I decided to ask Intercom themselves, through their support channel, for an answer, and I was given the following response:
This isn't actually something we do anything too special with, it is all to do with the configuration of the web server, both on our side and the side of the client.
This stackoverflow goes into more details on this, but keep in mind that whilst it is a ruby StackOverflow - it focuses on the web server set up, in this case nginx - but it could be any web server software.
How to preserve request url with nginx proxy_pass
This then allows your service to receive the requests, but also have access to the original server address - we then ask our customers to provide the custom domain they are using within their Article Setting to help us translate the server address to the correct help center.
I do hope this helps, if you do have any follow up questions I'm happy to try and help, but as you mentioned this does fall out of the scope of our team so the help I can provide may be limited.
Quite happy with the response, as they went above and beyond for me. Basically, the path I was on was the correct one. I decided to leave the question to help others. I also found the following related questions:
- How do I enable custom domains for my users?
- How to give cname forward support to saas software
- Custom domain feature for saas product customers
Good luck to those who find this.
QUESTION
I've set up a redbird based proxy following its README file examples.
By now I've configured single domain both for http and https and it's working well (https still using self-signed certificate).
But now I'm trying to configure it to use letsencrypt to automatically get valid ssl certificates and I'm getting stuck in following error:
...ANSWER
Answered 2020-Jan-16 at 09:13SOLVED!!
Many issues were involved at the same time (despite my lack of experience with either redbird and letsencrypt.
- The magic 404/Not found page: I guess it came from a lighttpd server that seems to had been preinstalled in my VPS.
Port 80 was redirected via iptables but I suppose in one or other configuration tweak I could have redirected incoming requests to localhost's port 80 (which is not redirected).
- My redbird missunderstanding: Looking at examples in its README file, I thought redbird were kinda "multi- reverse_proxy" in the sense that you could redirect http and https requests with single redbird instance.
But I finally realized that the (maybe not so well named) port option which is, in fact, an http port, serves only to configure a built-in unconditional http->https redirector (of which I already had read about, but I thought it were optional).
- The actual underlying issue: If your DNS have DNSSEC activated, you should define a CAA register in it pointing to letsencrypt.org.
At the moment I disabled DNSSEC instead because my provider's control panel doesn't allow me to create such register.
I discovered it while trying to get the certificates through certbot (sudo apt-get install certbot
which I must say that, If I had known about it before, I wouldn't had care about trying redbird's letsencrypt integration.
It is much more verbose (while redbird is more like a black box when errors arise) and pointed out that I needed the CAA register.
Here the notes I took about it (in case anyone could be interested):

QUESTION
I'm still programming my Flappy Bird game and I'm starting the "debugging" part now For that, I repaired some problems like the text of the score which did not appear and I even customized the icon as well as the name of the window (little attention to detail). Except that I have to correct a rather unfortunate detail, the speed of the fall of the bird is too slow. Thus, there are displacements impossible to achieve for the player, especially when the bird goes from a pair of very high pipes to a pair of very low pipes. However, the bird's jumps are perfect and I do not want to change them of course!
It was then logical for me to increase the speed of fall of the bird as it falls but nothing to do, I used various methods to program this increasing speed but they have not not completed. I tried, for example, to break down the movement of the bird but it did not change anything. I am aware that I have little experience but I thought to be able and I can not find similar topics on the net
In order for you to help me, I have reduced my program to the strict minimum and there is only the movement of the objects of the game, I am aware that I ask you too much help during this week and I am sorry but promised, after this adjustment you will never see me again!
...ANSWER
Answered 2019-Apr-27 at 12:10To increase the downwards speed, you must increase DY
, it is currently fixed at 5
; however, you are also using DY
in the sauter method, that you want to keep intact...
I suggest to add one variable DY_fall
, and set it at a larger value than the current DY
; this way, you do not need to modify sauter
.
You will need to:
initialize DY_fall
with the value you want.
change the movement of the bird in movement, to use DY_fall
:
canvas.move(image_oiseau, 0, DY_fall)
[EDIT]:
I added a variable GRAVITY
that increase the velocity of a downward fall, without interfering with the sauter
function.
This required adding yet another variable, dy_fall
that is increased by the acceleration from GRAVITY
, as long as the bird falls. This is reset to the default DY_fall
value each time the bird 'jumps'.
You will need to tweak the values to get a smooth game, but I think it should behave as you wished.
QUESTION
I'm programming a Flappy Bird clone but whatever I do, I can not display a game over screen if the bird touches the pipes. I did not think it was going to be difficult but it is. I managed to get a start screen with the debut and rapide function and canvas.delete ... However, I do not know how to do the opposite: display images / buttons or text if the game is over.
Thank you in advance for your help in hopes that the solution is simple but I just did not find it.
I tried to manage the image displays but the images just do not appear ...
Here are the pictures of the game (it's a mediafire link to download the zip file of the pictures)!
...ANSWER
Answered 2019-Apr-25 at 09:23You have use canvas.unbind("")
instead of canvas.unbind("",sauter)
which gives error message.
Now you should see Game Over image.
Pipes are stil moving.
You need global pause
in fin()
, debut()
, debut2()
.
And use pause
in deplacement
to stop animation.
QUESTION
I'm programming a Flappy Bird and I'm almost done, but I only miss one thing: the collisions between the bird and the pipes ... I managed to make sure that if the bird hit the ground or disappears from the screen, the game is over (thanks to the function fin() ). I would like the game to end also if the bird touches the pipes but I can not do it and people who ask for such a thing use, generally, Pygame :(.
Thank you in advance for your help in hoping that the solution is simple but that I just did not find it.
I tried to manage the collisions alone (we can see the corresponding part in my program) but the bird stops randomly ...
Here are the pictures of the game (it's a mediafire link to download the zip file of the pictures)!
...ANSWER
Answered 2019-Apr-24 at 13:41You have two approaches:
1- Determine which coordinates to check for a collision with the bird perimeter, safe zones, top and bottom y, width of the pipes, movement of the pipes, and other obstacles, etc. all quite interesting to implement and check, but a bit tedious and prone to errors.
2- Take advantage of the power of tkinter canvas, and use the method find_overlapping(x0, y0, x1, y1)
that returns a tuple of all items that overlap the given rectangle, or that are completely enclosed by it, and use this to determine if a collision has occurred, maybe with the use of a tag
to mark the obstacles.
My suggestion is to use find_overlapping
.
maybe something like this (pseudocode)
QUESTION
My question is about displaying and updating text, in order to display the score on screen.
I would like to create a score like the real game that would appear on the screen. But after researching Google, I have not found anyone wishing to increase a score on the screen ...
Indeed, I would like the score to increase each time the bird passes between the pipes and therefore whenever the pipes have an X of 67 pixels. So does anyone know how to do this?
...ANSWER
Answered 2019-Apr-22 at 13:01Here is one approach to display the scores: It uses a tk.Label
, that is updated at the same time the score increases.
The trigger that increases the score is currently a random call to on_change
; you can modify this to be a test if a pipe x coordinates becomes lower than the bird x coordinates (the bird successfully crossed the obstacle)
You can, if you want relocate the score label on the canvas.
