QUESTION

Azure Pipelines local agent failing to connect with SSL error

Asked 2022-Mar-29 at 19:29

We have an on premise server (Windows Server 2012 R2) with an Azure Pipelines agent running on it. Today (31st Jan 2022) this agent could not longer connect to our Azure DevOps organisation.

Judging by the log files, I assume this is because it is trying to connect with an older TLS version, which as of today is no longer available - https://devblogs.microsoft.com/devops/azure-devops-services-to-require-tls-1-2/

So I followed the instructions on how to make sure TLS 1.2 was enabled, and confirmed my settings in the registry editor and by running the PowerShell script suggested here - https://docs.microsoft.com/en-us/security/engineering/solving-tls1-problem#update-windows-powershell-scripts-or-related-registry-settings

All seems ok, yet it still fails to connect with the same issue. The machine has been restarted as well. If I try the URL it is requesting in the in built Internet Explorer browser, it fails, but with Chrome it succeeds, so it must still be trying to connect with TLS 1.2, but I don't know why. I've tried reinstalling the agent (with the latest build) as well but it fails on the same error. Any suggestions?

Enabling below Cyphers with IISCrypto on the server helped us fix the issue

Setting proxies when crawling websites with Python

Asked 2022-Mar-12 at 18:30

I want to set proxies to my crawler. I'm using requests module and Beautiful Soup. I have found a list of API links that provide free proxies with 4 types of protocols.

All proxies with 3/4 protocols work (HTTP, SOCKS4, SOCKS5) except one, and thats proxies with HTTPS protocol. This is my code:

ANSWER

Answered 2021-Sep-17 at 16:08

I did some research on the topic and now I'm confused why you want a proxy for HTTPS.

While it is understandable to want a proxy for HTTP, (HTTP is unencrypted) HTTPS is secure.

Could it be possible your proxy is not connecting because you don't need one?

I am not a proxy expert, so I apologize if I'm putting out something completely stupid.

I don't want to leave you completely empty-handed though. If you are looking for complete privacy, I would suggest a VPN. Both Windscribe and RiseUpVPN are free and encrypt all your data on your computer. (The desktop version, not the browser extension.)

While this is not a fully automated process, it is still very effective.

QUESTION

moving between section page using next and previous button in javascript

Asked 2022-Jan-03 at 11:53

In the same page I have multiple sections.

One section will be shown and this will happen using an active class.

In the same page I have li buttons 1, 2 and 3 and when I click on one of them the section related to it appears and the old one disappears. For that purpose I'm using Javascript.

Also in the same page I have a next and previous button. When I click on the next button the next section should appear and the old one should disappear.

And also the related li to the section should have the active class, the same thing for the previous: when I click on it it should go to the old section and the current should disappear and the li class should be active.

When I'm in the first section the previous button should disappear and when I'm in the last section the next button should disappear.

How can I implement this behavior for the next and previous buttons in this way using Javascript?

Any Help Please!!?

QUESTION

Understanding the effects of shared references on a nested data structure

Asked 2021-Dec-31 at 02:14

Ownership Tree

Hi,

I was trying to understand ownership concepts in Rust and came across this image (attached in this post) in "Programming Rust" book.

In particular am concerned about the "Borrowing a shared reference" part. In the book, the author says

Values borrowed by shared references are read-only. Across the lifetime of a shared reference, neither its referent, nor anything reachable from that referent, can be changed by anything. There exist no live mutable references to anything in that structure, its owner is held read-only, and so on. It’s really frozen

In the image, he goes on to highlight the path along the ownership tree that becomes immutable once a shared reference is taken to a particular section of the ownership tree. But what confused me is that the author also mentions that certain other parts of the ownership tree are not read only.

So I tried to test out with this code:

Someone should probably check my answer, as I am fairly new to Rust myself. But...

I think this is because a Vec doesn't uphold the same invariance as, say, a tuple or nested structs.

Here's a tuple version of the example you gave (Although tuples don't support pushing, so I'm just incrementing an integer):

How to map function directly over list of lists?

Asked 2021-Dec-26 at 15:38

I have built a pixel classifier for images, and for each pixel in the image, I want to define to which pre-defined color cluster it belongs. It works, but at some 5 minutes per image, I think I am doing something unpythonic that can for sure be optimized.

How can we map the function directly over the list of lists?

...

ANSWER

Answered 2021-Jul-23 at 07:41

Just quick speedups:

You can omit math.sqrt()
Create dictionary of colors instead of a list (that way you don't have to search for the index each iteration)
use min() instead of sorted()
