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.

Paraphrased from MikroTik SFP module compatibility table – MikroTik Wiki [WayBack]:
SFP+ interface compatibility settings with 1G links
For MikroTik devices with SFP+ interface that support both 10G and 1G link rate following settings are needed to be set on both linked devices for required interfaces. In order to get them working in 1G link rate.
- auto-negotiation disabled
- port speed 1G
- FD
Devices which SFP+ ports support 1G links:
- All SFP+ interfaces can be used in 1G mode if required:
- Only SFP+1 supports 1G link speed, SFP+2 is for 10G links only:
Devices which SFP+ interfaces can be used only for 10G links:
Some caveats leading to the above info: CCR1036-8G-2S+ SFP Problems – MikroTik RouterOS [WayBack]

You can get the below help when pressing these keys in an OpensSSH session:
- Enter
- ~
- ?
So thats Enter, followed by tilde, then question mark.
Then you get this help:
Supported escape sequences:
~. - terminate connection (and any multiplexed sessions)
~B - send a BREAK to the remote system
~C - open a command line
~R - request rekey
~V/v - decrease/increase verbosity (LogLevel)
~^Z - suspend ssh
~# - list forwarded connections
~& - background ssh (when waiting for connections to terminate)
~? - this message
~~ - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)
The one I use most is below; it leaves my tmux session alone.
- Enter
- ~
- .

The records represent the largest and most complete set of DEC records in existence, dating from 1947 through 2002, with the bulk from the company’s years of operation from 1957 through 1998, when they were bought by Compaq Computer. The collection is a comprehensive technical history of every major computing innovation at DEC, as well as its nontraditional business culture, which still serves as an industry model—nearly every contemporary company strives for a “culture of innovation.” The processing of the collection presents an extraordinary opportunity to study DEC’s product lines and business practices in depth as was never before possible. Very few companies as influential as DEC have as long a history, and the breadth and depth of this collection makes it unique in its comprehensiveness.

I could spend months in this archive (:
The PDP-11 and VAX-11/750 were the machines I first learned about DECNET, EARN and BITNET.
