chj··on Defrag Like It's 1993
But a defrag FAT jumps much much less, because the cluster slots allocated to the same file will be close to each other, often in the same sector. I would be surprised if DOS doesn't optimize for this case.
chj··on Intel seems awfully scared of Graviton2. Why pay for this ad on Google?
Intel is heavily investing now, meaning less profits in the coming years. That may put off a lot of existing investors.
chj··on This website has 81% battery power remaining
A suggestion: in bad weathers, the server should turn off during the time when there is less visitors and less sunshine. That probably could help it to serve a few more days (Of course the visitors must know when is the best time to visit)
chj··on Show HN: Mako – a full Bitcoin implementation in C
What do you mean "obfuscated"? This is the cleanest C code I've ever read in quite a while.
chj··on Ask HN: Are you also getting extremely obvious spam bypassing Gmail's filters?
This also happened to me. A very important email was put under the promotions. Usually I just kept the gmail tab open and didn't check my phone. Fortunately for me, I noticed this mail on my phone when I was clearing the unread status.

At the same time, all sorts of ads fall into my inbox repeatedly, even I deliberately mark them as spam or junk.

( Being cautious, I just checked the promotions again. And there is another important email lying. WTF!)

chj··on E-Ink Typewriter
I bought an eink display once, thinking to use it for text editing, but returned it the second day. There is nothing paper like when it comes to typing.
chj··on EU antitrust: Apple shouldn't use privacy and security to stave off competition
You are right. Every app lives in its Sandbox, so it is really not an issue.
chj··on What did ancient languages sound like?
Shijing is a collection of folksongs, so of course the words must sound very nice at the day, or the music behind them must be good. Jian Jia is in my opinion one of the best, which by the way rhymes well even in Mandarin.

But I don't like how it sounds in the video, and those weird sound bits (no idea what you call them) is not very friendly for singing either.

chj··on All Is Orwell
The author tried to paint Orwell just as "next man", but he can't even write half as clearly as Orwell does.
chj··on HTML Notepad – HTML WYSIWYG editor
Great choice of QuickJS. I would go with SQLite3 for storage though.
chj··on The Importance of Humility in Software Development (2020)
I thought it was from bwk.
chj··on Apple deletes Steve Jobs's “Thoughts on Flash”
I don't see how that could be acceptable in macOS world.
chj··on Apple deletes Steve Jobs's “Thoughts on Flash”
This is an insult to their OS team. macOS appears to be working just fine.
chj··on On UML
I have always been looking for something to UML as markdown to HTML. Any idea? Not text based tools though. PlantUML is nice, but it already feels like coding instead of modeling.
chj··on The Unparalleled Genius of John von Neumann (2019)
It was striking for me when I read his paper on self replicating machine, basically a design spec for DNA, and that was in the 40s. I still can't believe it.
chj··on I want a computer that I own
The author didn't define what owning means, but my guess is that, the computer must not run code without his approval, and must be able to run any code he wants.

Nowadays, you can only truly own an emulator.

chj··on Starlink is now Accepting General Pre-orders
> satellites need to be simultaneously in view of your terminal and a spacex earth station.

Does that mean that there is no connection between satellites?

chj··on Graphics Programming Black Book (1997)
Recently I also had a similar experience, when I was about to call it a day, then discovered that there is another 10%.
chj··on Permanent suspension of @realDonaldTrump
How can you tell a lunatic from a philosopher? Am I sounding like a lunatic now? You can refuse to answer, but why stop me from asking?
chj··on Computed goto for efficient dispatch tables (2012)
As of today, Computed goto is still much faster than switch, both on x64 or arm64.
chj··on Write code. Not too much. Mostly functions.
I only saw them occasionally, never tried to understand them before.
chj··on Write code. Not too much. Mostly functions.
Thanks. That is clear.
chj··on Write code. Not too much. Mostly functions.
I have trouble understanding this kind of talk. What's a problem domain, what's its dimension and normalization, and what's the high order logic all about? Can we use plain words people from our grandfather generation can recognize?
chj··on Apple Silicon M1 Emulating x86 Is Still Faster Than Every Other Mac
I guess there should be a difference between binary code translation and emulation. Emulation gives you a feeling that you are doing it instruction by instruction, but here from the benchmark, there are tasks heavily relied on system provided API, and behind those API calls are highly optimized native code.
chj··on On Apple's Piss-Poor Documentation
They really should hire the team behind MDN.
chj··on About iSH’s pending removal from the App Store
This is an emulator! everything runs inside a sandbox within sandbox.
chj··on Lambda Calculus Diagrams (2015)
> a similar knotation that Louis Kauffman

that's much simpler to understand than the lambda diagram.

chj··on Magit – A Git Porcelain inside Emacs
Insanely powerful.
chj··on Apple Disabling 'Sign in with Apple' for Epic Games on September 11
I was confused too, then I tried to picture them as AAPL holders, and it makes me feel more comfortable ever since.
chj··on Facebook says Apple blocked it from informing about App Store 30% fee
Why we didn't hear anything about it at the time?
