@PhilipSchonenb2 @blind_via It’s not set in stone. I’d probably be targeting a 130 nm process for the ASIC. Very little of my CPU architecture work has been outside of the chip, so a slow speed gives me a chance at making less mistakes. This personal project would be a reintroduction to VLSI for me.

If you want to suggest something, be my guest. Don't tell me what to do. This is my house. I have no problems with showing you the door if there is a problem.

@chrisf_cpuarch @51Yukkoro @kaeruZangyo 十分に伝わりました。 日本でも多文化共生は始まっています。特にムスリム。 教育機関にまで入り込んでいます。 頑張って声を上げているところです。

@51Yukkoro, @kaeruZangyo, @daihuku2023. Hello Japanese friends. I would like your help. I met an elderly Japanese man who can no longer work because he broke his femur and nearly died from pneumonia. He commented on my burger post and asked how much it cost. I learned the price was enough to pay for three days of his food! I would like to buy him lunch sometime. Can you please tell me if that would be ok culturally? And if so, are there any apps that let people share money? What is the best way to help?

@51Yukkoro @daihuku2023 @kaeruZangyo It requires strong leaders who will say no even if there are social consequences. Not many people can do that. God bless the ones who do (did this sentence translate ok?).

@chrisf_cpuarch @daihuku2023 @kaeruZangyo 正直怖いです。大多数の人が違和感を持っていても、正しいものとして政策やイベントが変更されていくなんて。でも、様々なことに配慮しすぎていると、みんなが疲れて逆の流れになる気がする。本当に好きなものを、何も考えず好きと言える世界が一番いい。

@chrisf_cpuarch ブリトーは日本でも有名です。 コンビニエンスストアで手軽に買うことがができて、私はハムとチーズが挟まったものが好きです🥴

Hello Japan. I am about to have dinner. This is a Mexican food called a burrito. It is a tortilla shell with meat and cheese inside of it. Very good.

They have an unexploded Iranian drone and found chips made in Europe. Meaning people were aiding a country that is blackballed. Many will end up in prison for it.

@2ray_degenemax Hello, hi, what’s up? All good phrases. Morning doesn’t really start until the sun rises. It’s still the evening right now. Good evening would be better than good morning, generally.

@ankoromochuu It started out as both being lowercase. Then black started being capitalized by academics. Then the morons got upset when people wanted to uppercase white. It was called “white supremacy”. It’s really stupid all around, except to the people who live in perpetual offense.

どうして?! 私は日本語で普通に「白人」「黒人」と書いてます!
BrokenSpiritlol@BSpiritlol

@ankoromochuu Did you know that in the translation Black is captialized but White is not? Interesting, right? I have a feeling you didn't mean to put one above the other and yet the translation capitalizes only one of them.

@NAITOTokihiro Absolutely. Writing code carelessly is dishonorable. One should always strive to be efficient, and that requires knowing what the computer is doing! It offends me when I see a single tab in chrome using 200MB or more!

@chrisf_cpuarch CとC++はコンパイル後のバイナリがある程度予想できるので、それを意識すると最適化が進みますよね。その最適化もだいぶ進化して、割と適当に書いてもそこそこの速度は出てしまいますが…

思うんだけど、Z80だとバグが出るとだいたい暴走するので、最終的にはバグはかなり少なくなるが、GDScriptのような高級言語とかスクリプトだと、多少おかしくても動いてしまうので、バグを内包したまま製品化ってのは普通にあり得る。こう考えるとアセンブラって最高なのでは?

@chrisf_cpuarch depends on the speeds you need to operate. if you are interacting slow enough, you don't need much. but when you get up to the higher speeds of ram, you need to length match your data and address busses independently

@NAITOTokihiro Most microcontroller work was with the ATmega AVR assembly. For desktop work x86 and x86-64, and purely ARMv9 now. Most of my code is C++ these days, but I still write it with how its assembly looks in mind.
