 *
 * Submitted by: voyager
 *
 * Design Overview:
 *   In this implementation, the limit order book is represented using
 *   a flat linear array (pricePoints), indexed by the numeric price value.
 *   Each entry in this array corresponds to a specific price point and holds
 *   an instance of struct pricePoint. This data structure maintains a list

Implement user API keys with Supabase

Rationale

JWTs are at the heart of Supabase authorization, but sometimes we wanna build an app that also gives users access via API keys; or perhaps only exclusively via API keys. As you may know, using JWTs as API keys makes them difficult to revoke and therefore a security issue.

We also want to ensure this doesn't significantly add to RLS polices, if at all.

Finally, we'd love to have this handled by Supabase and do as little as possible in our framework. This simplifies our code and reduces third-party libraries.

set "params=Problem_with_elevating_UAC_for_Administrator_Privileges"&if exist "%temp%\getadmin.vbs" del "%temp%\getadmin.vbs"
fsutil dirty query %systemdrive%  >nul 2>&1 && goto :GotPrivileges
::    The following test is to avoid infinite looping if elevating UAC for Administrator Privileges failed
If "%1"=="%params%" (echo Elevating UAC for Administrator Privileges failed&echo Right click on the script and select 'Run as administrator'&echo Press any key to exit...&pause>nul 2>&1&exit)

Phoenix in a splicing future (a.k.a death to all swaps)

Phoenix implements trusted swaps for users' convenience (to allow easy onboarding and offboarding). But it's not a satisfying solution for the following reasons:

• It uses two on-chain transactions for swap-in where one should be sufficient (one transaction from the user to Acinq followed by a channel open)
• Swap-out feerates are unpredictable (because we may fund the swap-out with unconfirmed previous outputs) which is frustrating for users
• It forces Acinq to use its own utxos, which doesn't scale well and is an operational burden
• If Acinq doesn't have any utxos available and the mempool is completely full, swaps are stuck which is also frustrating for users

param( [ScriptBlock] $scriptBlock )
<#
    .SYNOPSIS 
          Impersonates a user and executes a script block as that user. This is an interactive script
        and a window will open in order to securely capture credentials.
    .EXAMPLE
        Use-Impersonation.ps1 {Get-ChildItem 'C:\' | Foreach { Write-Host $_.Name }}
        This writes the contents of 'C:\' impersonating the user that is entered.
