replace by fee – Blockchain Unconfirmed Transaction (stuck)

Would anyone here please be able to tell me how to do RBF using the ledger nano- I can see the transaction has been stuck for about 12 hours now. The TX is 4acdaa2926d62893b15b186974bfff6cb2d13aa5c04c1121f58d9a2f607a4ee5 and it still has not been accepted.

I have been looking at accelerating it and also RBF, I have been unable to find anything for RBF in line with Ledger Live. I would really appreciate any help and if you could look at the transaction ID for me. I do not understand it unfortunately.

Many Thanks

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?

blockchain – How to make a block given transaction ids, fee ,weight, possible parents

I have a list of transactions in this form
6c665f1d784d2032a13fa0986f08a3306bb1a4430049787cb1b692ed0d5d9bde,302,1136,cbf57b4e77708a6d920a63e9584cb482b03c42374b6a49e6057170a9354a89c5
txid, fee, weight, possible parents

some of them have no parents i.e orphan transcations

some of them have 2,3 possible parents

So how would someone go about making a block out of them to maximize miner fee.

air travel – Does any train or bus company charge a no-show fee, or is that fee specific to some airlines?

Airlines sometimes have a no-show fee in case someone pays for a flight ticket but doesn’t show up to the flight.

I don’t recall seeing such a fee for trains or buses. Does any train or bus company charge a no-show fee, or is that fee specific to airlines?

I’m asking as this would help me identify which potential fees I should be aware of when purchasing train or bus tickets.


Replies to comments:

The whole idea (of charging a no show fee) is absurd. Suppose I buy a bottle of beer but don’t drink it. Will the company surcharge me for not using their product? – Weather Vane 7 mins ago

Some airlines companies do have a no-show fee, e.g. https://www.qatarairways.com/tradepartner/en/bookingnticketing/Penalties-and-Charges.html: “No-Show Charge: The charge made by reason of the failure of a passenger to use reserved accommodation, either through failure to arrive at the airport at the time fixed by the carrier, or through arriving improperly documented or otherwise not ready to travel on flight.”

the airline has been paid for the seat already, and can now re-sell it; that’s much easier (and more significant) money. – DavidSupportsMonica 3 hours ago

No-show fee != cancellation fee.

How would a railway prove you weren’t on the train? And I suspect its probably against EU rules. Afaik they permit a passenger to give up their travel plans at their own discretion. – Krist van Besien 5 mins ago

Some railways check when you enter e.g. high-speed train in China.

air travel – Does Qatar Airways have a no-show fee in case a passenger misses a flight (assuming the passenger only purchased a flight ticket and nothing else)?

https://www.qatarairways.com/tradepartner/en/bookingnticketing/Penalties-and-Charges.html states:

No-Show Charge: The charge made by reason of the failure of a passenger to use reserved accommodation, either through failure to arrive at the airport at the time fixed by the carrier, or through arriving improperly documented or otherwise not ready to travel on flight.

From my understanding, this means that Qatar Airways may charge a no-show fee in case a passenger misses a flight (even if the passenger only purchased a flight ticket and nothing else, i.e. didn’t book any hotel).

However I read some comments that contradict my understanding:

  • To me, it is quite clear that the hotel will want to be paid for accomodation you reserved, but did not pay for, because it could have been used by someone else. The flight has been paid for in advance, but the room was only reserved. So it is no-show as applicable to the accomodation, not the flight. – Weather Vane 10 mins ago

air travel – Qatar Airways flight ticket doesn’t agree with Qatar Airways website regarding the booking change fee. Which is one right?

I read on a Qatar Airways flight ticket with departure and return dates in spring 2021:

Endorsements: /C1-4 NON END/CHANG FEE APPLIES. VALID ON QR ONLY -BG QR

which from understanding means there is a booking change fee.

However, https://www.qatarairways.com/en/travel-with-confidence.html (mirror) states (the statement was already present at the time of the initial booking):

For all travel completed by 31 May 2022, rebooking fees will be waived if reservations are amended more than 1 hour prior to departure.

This seems contradictory to me on whether there is a booking change fee. Is it contradictory? If so, which source prevails, and if not, is there a booking change fee?


I tried to contact Qatar Airways but (‪888-777-2827‬) to nobody is picking up the phone after waiting 1.5 hours. The Qatar Airways webpage to change the booking doesn’t indicate whether there is a booking change fee.

woocommerce offtopic – Custom shipping method fee not added to invoice if user not logged in

I have a shipping method that queries a API for costing:

        );
        return $methods;
    }
 
    add_filter( 'woocommerce_shipping_methods', 'add_shipping_methods' );

}

The rate is pulled and added to the total but when a user that creates an account at checkout places the order, the shipping fee is not including. However if the same user while logged in places a order again the shipping fee is included. I can’t find any information online about this.

Please help if you can
