@openbsd: OpenBSD 6.4 is out now! https://www.openbsd.org/64.html

Grab the goods: https://cdn.openbsd.org/pub/OpenBSD/6.4
Upgrade guide: https://www.openbsd.org/faq/upgrade64.html

@mjg59: Psst being passionate about something doesn't make you good at it

This guide was super helpful for setting up Linux to pass the PCI device (audio chip) to Windows under qemu and dump all PCI I/O to a log file. Now to try to make sense of all the data...

Lazyweb: what's the best way to log all I/O for a PCI device under Windows to reverse engineer what a driver is doing? Run Windows under qemu with some kind of PCI passthru? A shim driver on native Windows?

garbage[43]: What year is it?

Chicago Area BSD Users Group is meeting next month
https://chibug.org/2018-10-10

After primarily using a fanless laptop for the past year, it's hard to go back to one with a fan even if it's not that loud or on constantly.

Coil whine is worse though. I've been playing with undervolting and limiting TDP to see if I can minimize it, but it's still there.

Aw shucks, the Intel ME seems to have been neutered and doesn't work any more

And we're live... thanks @mjg59

Flashing coreboot on the X210

These last two episodes of The Daily have been really hard to listen to

But on the plus side, ThinkLight!

I'm sad the modem is still a Winmodem though and won't work in OpenBSD

My 51nb ThinkPad X210 finally arrived that I ordered long ago. Kaby Lake R quad-core i5-8250, 1920x1200 IPS, outfitted with 16Gb RAM (expandable to 32Gb) and a 500Gb Samsung 860 SSD. I swapped in a palmrest from an X200 to get rid of the useless miniature touchpad.

I always picture Comic Book Guy writing the one-star reviews of @PushoverApp on Google Play and it makes me slightly less upset

First mention of Linux in a commercial BIOS? https://twitter.com/hdevalence/status/1038305566517415936

"Please be informed that there was a mix up with another server and your drives were removed."

Fridays are supposed to be read-only, right? One of my dedicated servers with 2 1TB SATA drives (softraid RAID 1) spontaneously restarted according to the iLO and now neither of the drives are recognized by the BIOS/AHCI controller. Sounds like a long day of tarsnap recovery...

OpenBSD on the Microsoft Surface Go

Yeah but for most people, there's no difference between Samsung and Android

Wow, my Galaxy S8 test device shows this notification every couple weeks recommending that I restart the device just because it's been a while. Android really is the new Windows.

What is the best practice for doing customer support when a user loses their 2FA device/token? Tell them they're SOL? Just reset manually and confirm by e-mail?

The last thing I backed is a year past its delivery estimate and they just e-mailed all of us to advertise that they're now selling the product from their own website (before sending out any product to backers).

I really need to stop backing things on Kickstarter. Aside from the Pebble and Thimbleweed Park, everything else I've backed has ended up being garbage.

Chicago BSD Users Group is meeting on August 8th, come out and eat pizza with us

https://chibug.org/updates/20

@rob_pike: Things should just work.

Do any services notify the account owner when an account login succeeds but 2FA fails/times out?

It's a `git reset --hard` kind of day.

I'd just assume never update anything once it works, but Google is mandating that apps target Android 8 or they won't be able to be updated in Google Play in a few months. And of course Android 8 changes everything about notifications and services that Pushover relies on.

Android Studio kept bugging me that stuff was out of date, so I let it update. Then nothing built because some deprecated things in the Gradle config needed to be changed, so I do that and now nothing builds but in a completely different way.

Halfheartedly considering using one of those crappy cross-platform frameworks to rewrite Pushover for Android just so I never have to deal with Android Studio and all of this Java crap ever again. So much time wasted with tooling upgrades that break stuff I care nothing about.

"OpenBSD still uses [CVS], and it's the main reason I've only rarely contributed patches. CVS is just that crappy."

Yeah, I'm sure that's why. #shithnsays

Schadenfreude-as-a-service: monitor eBay auctions you got sniped on and lost, then later notify you if that auction resulted in negative feedback because the thing being sold was garbage anyway

Pizza delivery guy: Here you go, enjoy
Me: Thanks, you too

Fetching node status from AirPort APs

You can enable SSH on it and it appears to use DJB's daemontools for some local services.

The hidden webcam is neat though. I'd never use it so it's one less thing to worry about.

Trying out OpenBSD on the new Huawei Matebook X Pro, but this as far as it gets (reboots as soon as the kernel loads). Unfortunately it has terrible coil whine, on par with the XPS 13. I seriously thought it had a spinning disk in it, it's so noisy.
