:realtek: のオーディオは近年のデジタルオーディオの普及でデジタルアンプを積んだデバイスが多いので結果的に使わないから気にならないが、NICはWindowsでタグVLANのドライバ入れたらブルスク吐きまくったの、まだ忘れられない。

💾 4am AMD Xorg/Kernel Debugging 💾

Ongoing fun ongoes, so much so. This iteration receives triple output: tty video (Display Port), COM1 redirect via DB9 to laptop running minicom, COM2 to the usual BMC SoL terminal watched from ipmitool on adjacent laptop.

Coming up, rebooting into GENERIC-DEBUG kernel rebuilt with remote GDM (kgdb) access via the COM1 link to laptop.

[속보] 중국 여객기, 김해공항에 남풍 불자 착륙 포기하고 김포로 회항 - 디지털타임스

dt.co.kr/contents.html?article

20여년전에 비슷한 상황에서 중국항공기가 김해공항 옆 산에 추락한 적 있으니 저럴만도 하지.

Z80はZilogという会社の製品です。
Intelの8080を大幅に拡張して便利な命令が多数搭載された8ビットCPUでした。
8ビットパソコンの時代の代表的CPUで、互換CPUも色々作られています。

ちなみに任天堂ゲームボーイのCPUもZ80(というよりは8080)から機能を大幅に削った独自のものが使われていましたね。

MSXturboRで搭載されたR800がZ80界(?)では最速クラスになるのかと思います。

When sharing a rapid news cycle, how do we share information that is validated and attributed?

"Speed of light" used to be the moniker for things "moving fast", e.g. "oh wow that happened at the speed of light".

It's worth mentioning that these days, especially with a never-pausing news cycle, there's something to be said for "moves at the speed of information".

e.g. The current news cycle in the United States right is paced at "the speed of information". When it feels like we're spreading Breaking News, or life saving information, it feels more urgent to spread the information than almost anything else.

This is a very "yes, and" sentiment!

Now is a great time to build a practice for how you can personally handle sharing things at the speed of information, which will have the double impact of making sure the information is 1 ) correct and 2 ) attributed.

When you see information you wish to share, esp if it's a news headline:

1. Do a quick search with your engine of choice ( :google: , :duckduckgo: )
2. Credit both sources

For # 2: this is because you have two sources, not one. *Your* sources are whatever post you saw that prompted your search *and* the results of the search.

Verifying in this way also has the double benefit of ensuring the original author is credited, which is doubly important for marginalized voices.

Let's use today's news about and the (labor data) for practice!

1. There's a :bluesky: post making rounds about DOGE + NLRB data
2. A quick search shows that the original source is an :npr: article by Jenna McLaughlin.

So that means when *I* post about it, my sources are: MattJay AND Jenna McLaughlin. *I* have *two* sources.

To capture this, I might make a post like:

There is a story breaking about gaining access to data! Sources are Jenna McLaughlin @ NPR:

npr.org/2025/04/15/nx-s1-53558

There is also additional analysis circulating by MattJay:

bsky.app/profile/mattjay.com/p

====

Posting like this:

1. Credits both sources
2. Fact checks and attributes
3. Isn't accusing

For # 3: It doesn't matter to my post what anyone else is or isn't doing. (And I would need to validate my own accusation.)

My only goals should be to validate and attribute what I wish to share.

>대한민국 전체 면적 330만 평을 한꺼번에 팔면 매국노이고, 천 평 만 평씩 쪼개서 팔면 매국노가 아닌가? 오세훈 서울시장은 1만4500평에 달하는 국토를 민간기업에게 매각하려고 했다. 특수목적에 따른 장기임대도 아니고, 그 땅과 산출되는 모든 것에 대한 양도권을 시민의 동의 없이 팔아버리는 것이다.

Intelの昔のCPU
16ビットの8086、バス幅を8ビットにした廉価版8088がありました

NECは8088互換のV25と、8086互換のV30を作りPC-9801シリーズにV30を搭載しました
高速化したV30HL、ピン非互換の後継V33、V33Aもありました
型番はV30はμPD70116、V25はμPD70320だったと思います

V30に周辺回路を搭載したV50やV50HLなど各種シリーズもありました

数値演算は昔はコプロセッサーで実施していて8087を別途付ける必要がありました。V30搭載98シリーズでもコプロは8087が使われていました

ちなみにV30には8086などにはない独自命令があり、この命令を使うアプリが少なからずあったので互換性のため386時代にもV30が搭載され切り替えできるようなっていましたね

PC-88VAシリーズではμPD9002というV30互換でかつZ80エミュレーションモード搭載の独自CPUが使われていました。これはCPUだけでなく周辺回路も1パッケージになっていたので、V50に近い製品でした

また型番忘れましたがNECのオリジナルCPU製品もあり、中の人がまだリーマンだった昔、そのCPU用のプログラムを書いたりしていたことがあります

My dream on the future of online ? Simple. One that supports and much better than it does now, so it actually serves mankind.

I want us to get past the madness of mindless , vicious spyware metaverses, and hungry . That's all hypercapitalism. Dehumanising us, eroding the fabric, so it can prolong itself and serve the elite owner classes.

starts offline, where we're humans of flesh and blood, living our daily life.
