I’ve “Reset this PC” in a macOS Bootcamp installation of Windows and have lost the ability to sign into macOS

After installing Windows 10 on my Macbook via Bootcamp, I’ve “Reset this PC” while in Windows, and now I’m no longer able to reboot into macOS.

I’m not concerned with losing any files on this computer (in either OS), but I would like to reinstall macOS, and then reinstall Windows via Bootcamp.

How would one go about this?

signature – Locally Sign transactions Blockcypher API

I’m having a problem that I can’t solve since yesterday with the blockCypher APIs when I try to create a new transaction and submit it.

https://www.blockcypher.com/dev/bitcoin/?shell#creating-transactions

i have to sign locally but their php or cURL code don’t work (they give me several problems)

I searched the internet but found nothing suitable.
many signing tools found online tell me to enter a message in addition to the private key, what message should I enter? does not refer to any messages here:

# next, you sign the data returned in the tosign array locally
# any ECDSA secp256k1 signing tool should work
# $PRIVATEKEY here is a hex-encoded private key corresponding to the input from address

do you have any algorithm that i can use in php?

forms – Should users be allowed to sign up using an email that has already been used…but it’s not yet confirmed?

Yes.

The “confirm email” is a side channel mechanism to confirm you own the email address.

If someone else tries to use an email address that they don’t own (either by accident or maliciously), that should have no bearing on the user who actually owns the address.

You are basing your trust on the fact that a user can access the email address, that is all you need to worry about. I.e. don’t worry about people who do not have access to the email address.

EDIT – “Don’t worry” is incorrect. You may want to worry about what happens if someone receives a confirmation email (which they didn’t initiate) and accidentally clicks on it. Make sure the ‘malicious’ user doesn’t have access to the account. Either mitigate it by having a timeout, or ask for password / shared secret after confirmation etc.

mac appstore – Why do I get “Sign in to use this application on this computer” for a non-App-Store app?

I’ve downloaded a free app from an independent developer. This is a custom app for a small community, and is not provided by the App Store. The developer provides it as a public download from Google Drive.

I extracted the .app file from the zip, placed it in /Applications, and then set permissions on it (as you need to do sometimes for zip-extracted apps):

sudo chmod -R 755 /Applications/PokeGenesis.app

Following this, I double-clicked to launch the app. However, I get a dialog stating, “Sign in to use this application on this computer”:

dialog

I’m already signed in to the App Store, but if “sign in” again with this dialog for fun, it dismisses itself for a second or two, and then reappears.

Is there a way to get around this? If not, what should I tell the developer to do to alleviate the issue?

I think maybe the developer is missing a step when making the build. I don’t think they test extensively on Mac; they simply create the app in Unity and then build it for multiple platforms.

If it matters, I’m on an M1, though I have Rosetta installed: MacBook Pro (13-inch, M1, 2020), Big Sur 11.2.3

single sign on – SSO for Intranet SharePoint Online Site on windows startup

I’d like to ask you if it’s possible to have a mandatory Single Sign-On when the employees log in to their laptops/desktops. We want to automatically open the intranet communication SharePoint Online Site, upon windows startup.

If yes, what is the best way to do it?

Any help will be highly appreciated.

Thank you!

debugging – is f”{expr=}” a new f-string expression (see equal sign before training brace)? from which version of python on?

I have received a python notebook that is full of expressions like f"{expr=}" that in my environment produce error messages:

var=7

print(f"{var=}")

  File "<fstring>", line 1
    (var=)
        ^
SyntaxError: invalid syntax

I suspect/expect that it could be in fact a new syntax for f"expr={expr}", i.e. as in the following print statement:

print(f"var={var}")

var=7

In fact I often use expressions like the latter for debug, and it would be nice to have a shorthand for it.

Is that a higher version of python than mine (3.7.6)? Or is it a customization of the fstring module?
Searching for it on the web or in SE was not productive.

And if it is not a standard feature, how can I get it to work?
