Lessons learned when using in general and -k configfile: everyone hates whitespace at the end of a line and so does bhyve; to successfully configure PCI and LPC devices you have to follow the man pages to the letter; bhyve(8) slightly deviates from bhyve_config(5) it seems; contents of man pages may change, depending on the version (surprise!); I’m probably not experienced enough to understand why there is a difference between “normal” PCI devices and LPC devices and why this is reflected in the config syntax and there are very good reasons why (if I remember correctly when I had a look) chose to use bhyve command line options rather than -k configfile in their source code; the man pages do not always make clear that some bhyve features are experimental (and not compiled in) and reading the FreeBSD handbook is always worthwhile; my system was not unusable due to active ZFS deduplication during my experiments; bhyve appeared to excel in terms of performance, I did not expect that my VM runs so smoothly on a 15+ year old laptop (SSD upgrade only), didn’t try Windows yet though. And after all this I’m still not sure why I’m supposed to bhyvectl —destroy my VMs, like does that free up some resources somewhere? I did note that this makes the device node of the VM in /dev/vmm disappear though.

Today, we're launching two things at @anewsocial: a Bridgy Fed settings page and a Patreon!

Bridgy Fed Config lets you switch bridging on/off for your Bluesky, Mastodon, or Pixelfed accounts. For ActivityPub-based accounts, you can add a custom domain to look native on Bluesky.

I’m installing a Windows 7 VM using and GEOM Gate at the moment. This is quite impressive (not the Windows part). I don’t have a CD drive in my bhyve machine, but my laptop has. So I put that Win7 CD into my laptop, SSH-remoteforwarded GEOM gate’s default port 3080 and told bhyve that /dev/ggate0 is a CD drive. And it just works, no questions asked, no complaints, super easy. GEOM Gate seems to exist for ages, just discovered it, never heard about it before.

Four terminal windows on an XFCE desktop. In the upper left: GEOM gate server output (laptop with CD drive). In the upper right: GEOM gate client output (machine without CD drive running bhyve hypervisor). In the lower left: Windows 7 installation boot screen (running on bhyve using remote CD drive). In the lower right: ggatec(8) manual page window.

Starting a new thread as I pay attention to what's going on in LA and Santa Ana. I'll include again my warning to followers that I will be posting about the protests for several hours. If you don't wanna see those posts, it would be best to mute me, but I will try to include tags as well.

"People are often curious about how much energy a ChatGPT query uses; the average query uses about 0.34 watt-hours, about what an oven would use in a little over one second, or a high-efficiency lightbulb would use in a couple of minutes. It also uses about 0.000085 gallons of water; roughly one fifteenth of a teaspoon." - Sam Altman in blog.samaltman.com/the-gentle-

Edit: please have a scroll through that PDF, because the ingredients below are just a few that I need to avoid, there's many more.

Are there pasta sauces without:
- tomatoes
- cream / cheese
- eggs
- large amounts of oil

garlic can be okay in small amounts after cooking

I'm trying to figure out an MCAS friendly way to eat pasta, and I'm kinda stumped.

There's this list of foods & their impacts on MCAS, particularly if they're high in histamines, histamine liberators, etc: mastzellaktivierung.info/downl

(I'm waiting for the cook book listed in that PDF to be delivered, because I'm struggling hard at times with what to eat, tonight I'm having to go pasta with tomato sauce which I know will affect me, but just because I don't really want plain rice or potatoes)

머스크가 이민자 시위에 대한 트럼프 대통령의 초강경 대응 방침에는 동의를 표하면서 과거 '선 넘는' 발언을 주워 담고 있다. n.news.naver.com/mnews/articl... 빡치는게 머스크 이 인간은 고학력 프로그래머, 개발자는 이민 받고 민주당 주지사/시장 있는 LA의 라틴계 이민자 시위는 폭력으로 제압하자는거라. 언팔했던(...) 백악관 부비서실장 계정도 다시 팔로우. 세계적인 하남자.

Latest in sea trials. An old 12v trolling motor provides propulsion. A pico is always-on and runs the basics, sensors, h-bridges and such.

An RPi4 will be the main autonomy hub to enable detailed mapping and surveys and such. But for now I can just push buttons in and move it around.

I built it almost totally out of scrap and epoxy. What a delightful waste of time! 😜

P. S. Note the crew on the bridge.

iPadOS 26 개발자 베타 하루 써봤는데 제법 괜찮다 맥북 사용성의 80% 정도 따라온 상태에서 터미널이 빠지고 셀룰러 + 터치를 추가한 정도?

물론 아직은 불안정해서 업데이트 권장은 못하겠지만 안정화되고 나면 생산성이 꽤나 좋아질 것 같음

I'm looking at the Astro tutorial— two minor questions—

- Do I understand correctly I'm allowed to eschew .astro files completely and specify everything via JSX?
- It says you can "integrate your favorite framework", and lists React, Vue, Preact, "Svete" and "Solid". I like Preact, I like React, and I know I'm not interested in Vue. Is it worth it to find out what "Svete" and "Solid" are?
- Can Astro be run in a "no framework" mode (IE: JSX becomes HTML on server side, no JS on client side)?
