BSDNow 265: Software Disenchantment
BSDNow 265 has a con report – the just-finished EuroBSDCon 2018 in Romania, plus the usual roundup of news items. One news item that will be useful someday: how to perform a BIOS update on a non-Windows computer.

Dumpoffon
If your kernel panics, the current state of memory can show why. That memory dump needs to be saved somewhere. ‘dumpon’ is the command to specify the device that will keep it. If you want to turn it off, you end up using the odd syntax ‘dumpon off’. Thanks to Aaron Li, there’s now a linguistically-sane comman [...]
LibreSSL 2.8.1 Released
We have released LibreSSL 2.8.1, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon.
This is the second development release from the 2.8 series, which will
eventually be part of OpenBSD 6.4. It includes the following changes:
* Added Wycheproof test vectors for ECDH, RSASSA-PSS, AES-GCM,
AES-CMAC, AES-CC [...]
EuroBSDcon 2018 slides available
EuroBSDcon 2018
is now over, and slides for OpenBSD-related presentations are now available
from the
usual place.
As always, there\'s some great reading there (especially for those of us
who were unable to attend the conference).
Unfortunately, there will not be any video this year.
New limits for unix socket sysctls
As a fix for wpa_supplicant, the upper limit on socket datagrams has been increased. What else does this affect? We’ll find out the hard way, which is why I mention it here.
Lazy Reading for 2018/09/23
I still have a backlog. Geez. I’m starting to worry I’m posting too much for anyone to read through.
After Years of Abusive E-mails, the Creator of Linux Steps Aside. Important to read to see the mind-boggling scale of money flowing into Linux; it’s a corporate UNIX at this point, with priorities determined by a number o [...]
In Other BSDs for 2018/09/22
Still running on extra links from previous weeks. Usually it takes a larger convention to cause this sort of backlog.

Hyper-V and DragonFly
I tried Hyper-V, and of course, I had to install a virtual DragonFly system. Sascha Wildner very helpfully pointed out that DragonFly on Hyper-V requires a legacy network adapter and a gen-1 image type; both changes you can make during initial setup. I’m noting it here for the benefit of future people walking down the same path.
Note: [...]
BSDNow 264: Optimized-out
BSDNow 264 is available now and has the usual roundup of news, including discussion of Threadripper performance that I’ve avoided.
OpenBSD Errata: September 21st, 2018 ...
Errata patches for the kernel have been released for OpenBSD 6.3 and 6.2.
On AMD CPUs, LDTR must be managed crossing between VMs.
Binary updates for the amd64 platform are available via the syspatch utility.
Source code patches can be found on the respective errata pages:

Chromium on BSD
Chromium, the open sourced base of the Chrome browser, builds on BSDs, including DragonFly. But not without some work.
SemiBUG meeting tonight
There’s a SemiBUG meeting at 7 PM tonight. Bring your troubleshooting lightning talks.
Ryzen buying advice
For anyone considering the purchase of a Ryzen system given the good benchmarks/power usage, here’s some discussion on users@ about which model is which.
Using acme.sh for Let’s Encrypt...
Peter Wemm\'s writeup about using acme.sh for FreeBSD.org served as inspiration, but I chose to do a few things different:
using DNS alias mode with sub-domains dedicated to ACME verification
delegating the sub-domains to the servers where the certificate will be needed
using bind on the servers where the certificate will be needed (wher [...]
