QUESTION
I am using twisted and PySide2 to create an app that can send information through network. However, twisted's reactor
and PySide2's QApplication
both need an event loop that runs forever.
What I need is when twisted receives a new message, I want it to update the message in the PySide2 Window. So that means twisted and PySide2 need to share the same memory. Here's some sample code:

QUESTION
For example, guestbook-ui service and bbs-ui service are installed in k8s.
And I want to map guestbook-ui only to the 8080 listener port and bbs-ui service to the 8081 listener port to the pre-generated k8s ALB ingress.
However, if you write and store the following in spec, all guestbook-ui and bbs-ui services are deployed to all ports of 8080, 8081, and routing is twisted.

QUESTION
I am working on certain stock-related projects where I have had a task to scrape all data on a daily basis for the last 5 years. i.e from 2016 to date. I particularly thought of using selenium because I can use crawler and bot to scrape the data based on the date. So I used the use of button click with selenium and now I want the same data that is displayed by the selenium browser to be fed by scrappy. This is the website I am working on right now. I have written the following code inside scrappy spider.

QUESTION
as the title states,
I am having trouble displaying my webpage properly on other screen resolutions.
I am not certain why it looks so bad on other screen resolutions and not scaling to the device itself.
I don't know exactly where to start, I would think that it has something to do with the way that I positioned my div containers but I am not too sure...
and would like a more experienced person to answer my question before I started messing with the code.
below is my HTML, CSS code:
...ANSWER
Answered 2022-Jan-04 at 19:50I advise you to follow many good techniques when developing a responsive webpage, here I explain to you:
- Replacing in your CSS absolute units such as px for percentages or em. It is always much better to work with relative measurements rather than absolute ones. From my experience, I always try to work with em, here is a conversion from px to em.
- Using responsive layouts like flex or grid.
- Adding metadata related to the viewport in the HTML head tag. I can see you haven't written it. As we can read in W3Schools viewport is the user's visible area of a web page. It varies with the device so it will be smaller on a mobile phone than on a computer screen. You should include the following element in all your web pages:
In conclusion, try to avoid absolute positioning because it is not the best option. Try to follow this advice and I am sure your webpage will turn so much better. :D.
QUESTION
Here is the code for the spider. I am trying to scrape these links using a Scrapy spider and get the output as a csv. I tested the CSS selector separately with beautiful soup and scraped the desired links, but cannot get this spider to run. I also tried to account for DEBUG message in the settings, but no luck so far. Please help
...ANSWER
Answered 2021-Dec-26 at 13:45Just a guess - you may be facing a dynamic loading webpage that scrapy cannot directly scrape without the help of selenium.
I've set up a few loggers
with the help of adding headers
and I don't get anything from the start_requests
. Which is why I made the assumption as before.
On a additional note, I tried this again with splash
and it works.
Here's the code for it:
QUESTION
The sizeof
builtin can take either a type or an expression, and will return the appropriate value.
I'd like to build a macro that uses _Generic()
expressions to do something similar. In particular, I'd like to be able to pass either a type name or a value as the parameter, just like sizeof
.
As a trivial example, I can do something like this:

Answered 2021-Dec-03 at 19:56Your compound literal idea will work if you combine it with typeof

However, please note that typeof
is a a GCC C language extension, so it might not work in every C compiler.
QUESTION
I have an issue when in try generating mesh around a spline.
Everything is good but at random point on the spline the mesh is "twisted". Some of triangle are shifted (cf picture)

More detailed mesh

And the code who create the mesh. I do not start filling the array at index 0 because i generate the cap of the "tube" before (i can share the code if needed)
...ANSWER
Answered 2021-Nov-24 at 22:41The problem is that only knowing the current position and direction of the pipe isn't enough.
To illustrate, start with two identical pipes lined up going forward, with the top marked in red and the bottom marked in cyan with paint. Bend pipe 1 upwards, then to the right, then back down, then to the right. Bend pipe 2 downwards, then to the right, then back up, then to the right. Both pipes will end up at the same point and direction, but the red and blue sides at the end are in different positions:
(also applies to round pipes, of course)
If you don't account for this ambiguity and always treat the "top" as red, you would have to have points in the pipe where the red paint "twists" around your pipe. The same principle is what is happening to the edges & faces of your mesh.
To account for this, you can use the power of quaternions to calculate where the "first vertex" on the current ring corresponds to where the "first vertex" should belong on the previous ring.
The position of this "first vertex" we will call the "index direction". We can think of this direction as the direction of our "red paint". In reality it will be the first vertex for the ring at that location in the spline. So, the same thing your perpendicularVect
did!
So, you can begin the pipe by finding any valid index direction. For the purposes of getting rid of these twists, it doesn't matter how this is found. Cross product with a constant parameter works great, just be sure to handle colinearity.
Then, at each following step, find the minimal rotation which rotates the previous direction of the pipe to the new direction. Quaternion.FromToRotation
does exactly this. Then, apply that rotation to the index direction to find the new index direction.
Regardless of the step you are on, once you have your index direction, you can proceed as you were as if it was your perpendicularVect
. Rotate it around the pipe's axis to find the other points in the ring, and connect adjacent points to each other. Then, continue to the next step.
Altogether:
QUESTION
This is a follow up to my previous question. I recieved some good answers there, but, because of the way I simplified my actual problem, I think I misled the answerers, and I hope to remedy that here.
TL;DR I have a typeclass Category
from constrained-categories
which constrains the domain/codomain of it's Category
s using a TypeFamily ("constraint family") called Object
. I would like to make a Free Category

constraint.

data type, and its constrained-categories.Category

QUESTION
I've been tasked with creating a reverse proxy that is required to make a TLS connection to the proxied service. The certificates I have are unique per request, and in-memory.
I haven't had much luck getting it right, and I've tried a number of things. Here's where I'm at now, hopefully someone can help:
...ANSWER
Answered 2021-Oct-01 at 17:10For TLS (ie https, which is http with TLS) you must connect to the correct server port. It is usually port 43 or port 8443. It is never the same as the port used for http. So this means that to start, the server must provide a port for TLS, although most do.
The only code you've shared has nothing to do with the connection to the server.
Since you've not shared any of the code making the request to the server, it is not possible to show where it is wrong.

Install twisted
You can use twisted like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
