replace by fee – Using RBF in python application

I’d like to create transactions within my python application, that support replace-by-fee RBF (BIP125).

Apparently, if I want to be able to replace my transaction later on, I need to signal that already in the first transaction. I saw that I’d have to do something with the sequence field for that, but I didn’t quite understand it.

Is there any library that would help me with that, or do I need to craft this transaction manually, and if yes, how?

Sorry for being so vague, but this RBF-stuff is giving me a hard time.

Reading the answer to the question What restrictions are there to the application of opt-in RBF?, is only confusing me more.
Why would setting the sequence number to MAX-1 mean 2 things at the same time (transaction uses locktime and transaction is replaceable)?
What if I don’t want to use locktime but only make my transaction replaceable?

Can chained function calls replace nested calls?

I have a function generateResult() that returns a number. I then need to do something with this result via handleResult(number) that returns a string. The example is fictitious, I have complete control over handleresult and generateResult

This can be coded in several ways :

x = generateResult()
y = handleResult(x)

which can be simplified to

y = handleResult(generateResult())

Alternatively, I could chain the functions

y = generateResults().handleResults()

I am looking for a “consensual” (generally accepted) approach to these two ways of coding. Since the end result and testing approach are the same, I would like to use the least surprising one.

The content is amateur coding in a home environment, but I would like to possibly use best practices just in case.

Python script to replace GitHub password with tokens

I manage a fleet of IoT devices.

As for now, GitHub announced that the username-password authentication would be deprecative soon, so I have to change the password on each device to the GitHub access token.
I store the new token at AWS secrets manager. And those are the scripts to extract the new token and implement it on the device.

update_github_token.py

from get_aws_secret_manager import get_secret
import subprocess

SECRET_NAME = 'prod/GitHub/Token'
GITHUB_TOKEN_KEY = 'droneGitHubToken'
GITHUB_USER_NAME = 'danAairlines'
GITHUB_REPO_OWNER = 'Aairlinesfox'


def get_github_tokken():
    github_secret_dict = get_secret(SECRET_NAME)
    return github_secret_dict(GITHUB_TOKEN_KEY)


def build_token_github_url():
    github_token = get_github_tokken()
    return f'https://{GITHUB_USER_NAME}:{github_token}@github.com/{GITHUB_REPO_OWNER}/drone.git'


def update_drone_github_url():
    github_url = build_token_github_url()
    subprocess.run(f'sudo git remote set-url origin {github_url}', shell=True, check=True)


if __name__ == '__main__':
    update_drone_github_url()

The second module is AWS script, as appears on their website. I just modified the get_secret function by adding args. And at the end of the file, I added:

secret = json.loads(get_secret_value_response('SecretString'))
        return secret

            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response('Error')('Code') == 'InvalidParameterException':
            # You provided an invalid value for a parameter.
            # Deal with the exception here, and/or rethrow at your discretion.

            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
    else:
        # Decrypts secret using the associated KMS CMK.
        # Depending on whether the secret is a string or binary, one of these fields will be populated.
        if 'SecretString' in get_secret_value_response:
            secret = json.loads(get_secret_value_response('SecretString'))
            return secret

        else:
            decoded_binary_secret = base64.b64decode(get_secret_value_response('SecretBinary'))```

sql server 2016 – SQL Mirroring Replace Certificates

I have inherited two SQL 2016 servers with two mirrored databases.

They have been built with certificates as they are in a workgroup, the certs expire in six months. I am trying to understand the process to replace the certs with new ones with a longer lifespan, and if the process can be done online with no downtime?

Just to confirm the certs haven’t expired yet, I am just being proactive.

I am thinking something like this:

  • Create new certs with longer expiry dates
  • Backup the certs to files and copy between primary and secondary servers
  • Restore the certs with Authorisation to the existing mirror users no need to create new users
  • Alter the existing end points to point to the new certs
  • Clean up

Realizar un replace() dentro de una función Python

.
Hola, tengo una función que debe ser aplicada en 300 archivos Excel path_to_file

def DataBaseGenerator(path_to_file):
    '''
    Parametros
    path_to_file(string): Caminho ate os arquivos
    
    return
    df_final(DataFrame): DataFrame com todos os calculos de temperatura e power.
    
    
    '''
    #Load de uma lista com todos os arquivos.
    _list = (os.path.join(path_to_file,i) for i in os.listdir(path_to_file))(:-4)
    
    #Cria o dataframe vazia para armazenar os dados.
    df_final = pd.DataFrame(columns = ('Horário', 'Temperatura', 'Potência'))
    _trash = ('11967608', '11967609', '11968098', '11968099','11968752', '11968753', '11969030', '11969031', '11969114','11969115', 'Horário')
    
    #Primeiro for percorre a lista de arquivos.
    for i in _list:
        print(f'Arquivo:{i}')
        #i=i.e i= "20190122.xlsx"
        #Carrega o DataFrame
        df = pd.read_excel(i, skiprows=7, usecols=('Potência','Temperatura','Horário'))
        
        #Preprocessamento antes de realizar os calculos.
        for j in _trash:
            df = df(df.Horário != j)
            
        df('Horário')=df('Horário').astype(str)
        
        df_final = Fill_df(df_final,df)
        
    return df_final

Tengo un problema con las columnas Potência y Horario que debo reemplazar valores numericos por ejemplo 2,15 para 2.15

Es posible realizar un .str.replace(',','.') dentro de la función def DataBaseGenerator(path_to_file) específicamente en la linea df = pd.read_excel(i, skiprows=7, usecols=('Potência','Temperatura','Horário')) que sea aplicada en todos los Excel?

Pues yo intente aplicar lo siguiente:

 df = pd.read_excel(i, skiprows=7, usecols=('Potência','Temperatura','Horário').str.replace(',','.'))

y obtengo el error:

AttributeError: 'list' object has no attribute 'str'

microsoft word – How can I replace a character with a new bullet point

If I copy and paste a PDF with bullet points into Word, Word no longer detects the bullet points

I created a Word document, added some bullets and printed to PDF and the result is

enter image description here

I then copy and paste the text from the PDF into Word, and I get

enter image description here

I understand that it no longer see’s the black circles as bullet points

I don’t see any options for a magic paste in Word

My question therefore is, is there something like a find and replace operation that will convert the black circles into bullet points, so I end up with something like the first picture in this post.

Does receiving a student visa replace my existing business travel visa? (China)

Does receiving a student visa replace my existing business travel visa? Is it possible to hold two visa types simultaneously?

I still hold a now rare 10 year multiple entry business travel visa (though COVID-19 rules mean this is temporarily unusable). If I receive a new visa e.g. student visa, must this replace my existing visa? or put another way, what would I expect to see when I receive my passport back from the embassy?

How can I replace WordPress standard process of editing posts with making WordPress use a custom page?

I have the following problem: When I want to edit the content of posts, WordPress simply opens its standard page editor where I can add and arrange blocks, control the general page design and what not. That page editor comes with tons of controls and in my case also all kinds of additional parameter areas for various plugins (like Yoast SEO and Content Egg etc), so it looks kind of cluttered or freightened with many elements not needed when you simply want to edit a post’s content. Only among others can I edit the post content (text) there.

What I would like WordPress to do is to open a custom page where I can just edit the post content (text) and submit the changed text back to the underlying database.

So how would I go about directing WordPress to opening some custom page I have created where I can simply edit the post content, without all the editing facilities of WordPress around?

The custom post editing page would probably a form with a message field where I can edit and submit the post content. How exactly would I need to build that form so that the (edited) post content is stored back into the database when I click on the form’s submit button?

python – How to replace a string with parts of it between markers (regex)?

I have a text, let’s say:

Lorem ipsum dolor sit ((amet)), consectetur adipiscing elit, sed do eiusmod ((time (sample)|tempor)) 
incididunt ut ((labore)) et dolore magna aliqua.

I want to replace the ((time (sample)|tempor)) with tempor.
The structure is always the same: ((string to remove|string to extract)) and can appear several times in the text.

I tried regular expressions in regex, but I wasn’t successful without cutting off half of the text: re.sub(r'(.*?|', '', text)

How can I replace the string?
