Edit 20260501: be careful, as this damaged the NAND memory of my router because of too many write cycles. Root cause: too high update frequency.
Interesting: middelink/mikrotik-fwban: Use your Mikrotik firewall to do fail2ban like blocking of unwanted IPs. Written in Go.
It might beat these (that just count SSH connections, not failed connection attempts)

The operation could not be completed.

Include In Project
I’ve got a bunch of PowerShell projects in a solution. In some of them, I can include new files, in others I get the below error.
The diff of a good/bad project is below as well.
Two questions:
- Does anybody know how to work around this?
- Does anybody know how to find the actual error for this?

For one of my VMs I forgot to note which of the initial password I had changed, so I wanted to check them.
Since I didn’t have a keyboard attached to the console and ssh wasn’t allowing root, I needed an alternative than actual login to test the passwords.
Luckily /etc/shadow, with getent and openssl came to the rescue.
Since getent varies per distribution, here is how it works on OpenSuSE:

A while ago, I had to fix some stuff in an application that would write – using a binary mechanism – UTF-8 and UTF-16 strings (part of it XML in various flavours) to the same byte stream without converting between the two encodings.
Some links that helped me investigate what was wrong, choose what encoding to use for storage and fix it:

Ask GetLocaleInfo (example function GetAnsiCodePageForLocale included): [WayBack] How can I get the default code page for a locale? – The Old New Thing
UINT GetAnsiCodePageForLocale(LCID lcid)
{
UINT acp;
int sizeInChars = sizeof(acp) / sizeof(TCHAR);
if (GetLocaleInfo(lcid,
LOCALE_IDEFAULTANSICODEPAGE |
LOCALE_RETURN_NUMBER,
reinterpret_cast<LPTSTR>(&acp),
sizeInChars) != sizeInChars) {
// Oops - something went wrong
}
return acp;
}
And even though you didn’t ask, you can use LOCALE_IDEFAULTCODEPAGE to get the OEM code page for a locale.
Bonus gotcha: There are a number of locales that are Unicode-only. If you ask the GetLocaleInfo function and ask for their ANSI and OEM code pages, the answer is “Um, I don’t have one.” (You get zero back.)

One day I need to research how to get the conversions right for this: How do I Check DHCP Lease info in terminal – Ars Technica OpenForum as I think that ipconfig getoption en0 lease_time gives me the value in a different format than date -r expects.
Also:
At T1 seconds (typically set to 0.5*lease_time) after the last successful renewal, the DHCP client attempts to renew it’s lease with the DHCP server that granted it’s current address via unicast. If unsuccessful, at T2 seconds (typically set to 0.875*lease_time) after the last renewal, the DHCP client attempts to rebind with any DHCP server via multicast.
