Different AirDrop dialogs between two Macbooks sending same file to an iPhone

Have a problem which I cannot get solved actually.
It’s related to sending a file (GPX) downloaded on my computer(s) via AirDrop to my iPhone 8 (iOS 14.4.2).

On one macbook (MBP 2019 BigSur) I just get a dialog to open the AppStore or to save the file in the Apple “Files” app (see image below).

Generic dialog

On the other macbook (MBP 2015 BigSur) I get for the same file a nice dialog offering me the apps which are installed on the phone and capable for the GPX file format (see image below).

meaningful dialog

As you see in the first image there appears my name and so it might be someting related to a “binding” between iPhone<>Laptop and if so is that changable to two devices or where can I change it to have the MPP 2019 opening the 2nd type dialog.
Actually tried to reset my phone settings as explained in apple support to get the “Trust this Computer” dialog but even after a reset nothing in the above explained behavior has changed.

transactions – Minimum for sending BTC from BTC wallet

Is there a particular minimal amount of Bitcoin one is allowed to send?

0.00005460 BTC.

According to Paxful

Before making any transactions or depositing Bitcoin to your Paxful wallet, it is important for you to know the minimum BTC amount allowed by the blockchain network for a transaction.

Currently, the smallest amount of Bitcoin you can send or receive in a transaction is 5460 Satoshis, which is equivalent to 0.0000546 BTC.

One of the reasons behind this limit is to prevent spamming transactions.

Although Paxfull isn’t Saint Bitts LLC (owner of Bitcoin.com) they are talking about Bitcoin network limits, not proprietary company limits. So it applies. See also What’s the minimum transaction with bitcoin?

To send smaller amounts you’d have to use something like the Lightning Network (LN).

Currently 0.0000546 Bitcoin equals approximately 2.71 EUR

Your 0.001707 BTC is larger than this limit. So this is not the cause of your problem.


I keep on receiving the error at confirm “Insufficient funds for fee”

Take the transaction fee into account

“Insufficient funds” is an entirely different problem. When you send x amount of money, for the recipient to receive x you also have to send a transaction fee y. So the amount needed in your wallet at the start is x+y.

See https://bitcoin.stackexchange.com/search?q=insufficient+funds

The size of y depends on

  • The complexity of your transaction (especially amount of small change rustled up to make the amount)
  • How busy the network is
  • How long you are prepared to wait for the transaction to go through. Minutes? Hours? Days? Weeks?

Many wallet programs help you to choose an appropriate fee. You can also use a search engine to find sites that report on current fee-rates.

forms – Sending Message Information via XmlHttpRequest or Ajax

Please bare with me as I am new to web programming and have spent a long time trying to figure this out on my own. I am using node.js with express and am attempting to send data from my client to the server in order to send an email from a “Contact Me” page.

My simple test html form is this:

<form action="email" method="POST" class="contact-form">
  <input type="text" id="name" placeholder="Your Name" value="Test">
  <input type="email" id="email" placeholder="Your Email" value="Bob@bob.com">
  <input type="text" id="subject" placeholder="Subject" value="Subject of Email">
  <textarea cols="30" rows="7" id="message" placeholder="Message" >I was here.</textarea>
  <input type="submit" value="Send Message" class="submit">
</form>

This is the code for my server using XMLHttpRequest:

const contactForm = document.querySelector(".contact-form");
let name    = document.getElementById("name");
let email   = document.getElementById("email");
let subject = document.getElementById("subject");
let message = document.getElementById("message");

contactForm.addEventListener("submit", (e) => {
e.preventDefault();

let formData = {
  name: name.value,
  email: email.value,
  subject: subject.value,
  message: message.value
}

let xhr = new XMLHttpRequest();
xhr.open("POST", "/");
xhr.setRequestHeader("content-type", "application/json");
xhr.onload = function() {
console.log(xhr.responseText); //This never runs
if(xhr.responseText == "success") {
  alert("Email sent"); //this never fires
  name.value = "";
  email.value = "";
  subject.value = "";
  message.value = "";
} else {
  alert("Something went wrong!"); //nor does this
}

  console.log(xhr.statusText); //nor does this
  xhr.send(JSON.stringify(formData));
}

});

I also have the exact same thing using ajax here.

const contactForm = document.querySelector(".contact-form");
let name    = document.getElementById("name");
let email   = document.getElementById("email");
let subject = document.getElementById("subject");
let message = document.getElementById("message");

contactForm.addEventListener("submit", (e) => {
  e.preventDefault();

  let formData = {
    name: name.value,
    email: email.value,
    subject: subject.value,
    message: message.value
  }

  $.ajax({
    type: 'POST',
    url: "/",
    contentType: "application/json; charset=utf-8",
    datatype: 'json',
    data: formData,
    success: function (response) {
        console.log(response);
    },
    error: function(error) {
        console.log("error");
    }
 });

});

For both cases, my server side code is this:

const express = require("express");
const app = express();

const PORT = process.env.PORT || 3000;

//Middleware
app.use(express.static("public"));

app.get("/", function(req, res) {
    //send html file. Do this so that other code can run.
    res.sendFile(__dirname + "/contactform.html");
});

app.post("/", function(req, res) {
     var data = JSON.parse(req.body)
     console.log(data);
  });
  

app.listen(PORT, function(req, res) {
    console.log('Listening on port ${PORT}');
});

My XMLHttpRequest version does not run the onload code. The ajax version returns a 500 internal server error and the data sent is undefined.

Any help would be appreciated.

sharepoint online – Approval Workflow SP2013 Not Sending Approval Email

So I have created the following workflow.

When a person creates a new list item, the variable Approval Status is by default Pending. So once the list item is created, it send an email to who created the request letting them know that it has been submitted for approval.

Next, the workflow will create a Task to send to HR to either approve or reject the employees leave request. If accepted, I have it showing on a calendar view, and if not it doesn’t show up on the Calendar.

Everything up to that works just fine.

For some reason, when it is changed to approved or rejected from Pending, it will not send either of the emails I have created to notify the employee of his/her approval rejection. Why is this

enter image description here

sharepoint enterprise – Infopath hanging on “Sending data to the server” even though data was sent. but workflows don’t begin

My InfoPath form had been working fine but suddenly any new entries after submit hang on “Sending data to the server”.
Oddly enough the new data is written BUT the workflows that should begin now do not.
The other clue is that I can still start the approval workflow manually but when I try to approve, after clicking “approve” now it would just be stuck on “Working on it – please wait while your task is updated.”

And lastly when I try to manually approve it through “workflows” on the browser, I get

Sorry, something went wrong 
This task is currently locked by a running workflow and cannot be edited.

I have scoured the web for answers, I have tried everything from clearing the browser cache to swapping over a “larger” copy of Core.js and nothing.

I could sure use some good karma back my way. I have a day trying to get this to work.

Is it okay that a payment app is sending my payment details via a GET request?

I was trying to use a state-owned mobile payment app to conduct some transaction on the internet and, thanks to an error message, I found out that my card number and the amount I’m paying were sent via a GET request.

Other data on the request: the name of the service and an HMAC. And, yes, it’s on HTTPS but I don’t believe this really helps if the data is in URL.

Is this secure? Shouldn’t such details be sent over a POST or a PUT request? I’m not a security expert so maybe I’m missing something here.

How do I take screenshot of restricted area with delay while sending the screenshot to clipboard at the same time?

How do I take a screenshot of restricted area with delay while sending the screenshot to clipboard?
I would like to get the screenshot stored on the clipboard to be able to paste it afterwards.

gnome-screenshot -a -c works but gnome-screenshot -a -c --delay=2 does not work. It outputs the following:
Conflicting options: --area and --delay should not be used at the same time.

In case it is not possible to do this with gnome-screenshot, what other alternatives are there out there?

Thanks

development – Difference between sending a transaction on bitcoin and bitcoin cash

I am making a script that connect to a node and do a transaction, everything from scratch, what would be the difference if I wanted to use the same script for bitcoin and bitcoin cash.

I have already changed the seed discovery peers and the magic number related to each protocol, but is there more things I need to change so that I can communicate properly for each kind of protocol ?
