Mistakenly entered Open League for #umamusume #libracup and thought I had really messed up. Made a team of B-ranks as fast as possible. My Taishin is a bit OP....

The first champions meeting I didn't try to make good aces for ended up being the only CM I got 1st place in so far. The Tokai Teio from my first Teio career won the day. LOL #umamusume #leocup

It is a consistent pattern of bad behavior. I have even called him out on it just to be blocked by him. Some examples:

Margot Kraus@markekraus· Feb 20

Guess the resulting values of $x and $y. #PowerShell #pwsh #CursedCode #CodeInAltText

$x, $y = 1, 1
$null = + $x ++ + $y ++ + ++ $x

$x = $y + + + + + $x
$y = $y + - + - + $x
$x = $y + - + - + $x
$y = $y + - + - + $x
$x = $y + + + + + $x

$null = - $y -- - $x -- - -- $y

$x, $y

in fact.. all the ps*1 files are signed there.. It doesn't rule out it being an exploit.. but given this is the same link provided int he doc for this tool, and it's signed by MSFT, I think the probability is really low.

$The picture shows the code signing for TSS PowerShell files.

I'll just leave this less intuitive version here as my contribution to the conversation...

$Shows PowerShell command line code to get the Friday 13ths of a given year using the the first day of the week of the previous 12 years to detect for years starting on Sundays and using that iterator as the month in the current year that contains a Friday 13th. PS C:\temp> $y=2025; 1..12 | where {!(date $y-$_).DayOfWeek} | Foreach {date "$y/$_/13"} Friday, June 13, 2025 12:00:00 AM PS C:\temp> $y=2026; 1..12 | where {!(date $y-$_).DayOfWeek} | Foreach {date "$y/$_/13"} Friday, February 13, 2026 12:00:00 AM Friday, March 13, 2026 12:00:00 AM Friday, November 13, 2026 12:00:00 AM$

Yeah, it's okay when you use the command line interactively, but it starts to hurt if you do it in a loop or something. at n=10,000, the difference between get-date and date is measured in MINUTES

$Image demonstrates the extreme difference in execution times between get-date and date at n = 10,000. PS C:\Users\MarkLocal> $n = 10000 PS C:\Users\MarkLocal> (Measure-Command{1..$n | %{$null = date}}).TotalMilliseconds 270625.4923 PS C:\Users\MarkLocal> (Measure-Command{1..$n | %{$null = get-date}}).TotalMilliseconds 323.3579 PS C:\Users\MarkLocal> [timespan]::FromMilliseconds(270625.4923) - [timespan]::FromMilliseconds(323.3579) Days : 0 Hours : 0 Minutes : 4 Seconds : 30 Milliseconds : 302 Ticks : 2703021345 TotalDays : 0.00312849692708333 TotalHours : 0.07508392625 TotalMinutes : 4.505035575 TotalSeconds : 270.3021345 TotalMilliseconds : 270302.1345$

Couple that with the DontShow Parameter Attribute Setting. The param will no longer be available via tab completion.
