innocenat··on Thunderbolt, Displayport and Docks
There is plenty of bandwidth if DP 1.4 is used. DP1.4 only require one superspeed pair for 4K@60Hz, leaving the other pair for USB3.1 data connection.
innocenat··on Thunderbolt, Displayport and Docks
I am pretty sure DP cannot be encaspulate in USB 3.1/3.2. (USB4 can carry DP over Thunderbolt), so alternative mode MUST be used (1 highspeed TX/RX pair for USB-C 5/10Gbps, and another pair for DP Alt Mode).

That just mean the charger is underpowered.

> Except it does work, for charging at least.

Most phone can charge off of the base 5V/3A profile, so it works for phone.

But many bigger devices don't. I think most laptop only charge off of 20V mode, so it won't work if the charger can only do 5V or 9V. Some tablet also only do 9V, refusing to charge on 5V.

But that isn't "locally"?
innocenat··on USB4 v2 is also 120 Gbps
This isn't even new. Even USB 3.0 (the first gen, later rebranded as USB 3.1) micro-B to A cable, which has been around for at least 10 years at this point, is already not good for mouse. Nor is my USB-C 2.0 with 60W PD cable.

Where is write contention coming from if it's operated locally?
innocenat··on Complete Introduction to Particles in Japanese
I don't know what's happening but the font on that website rendered so bad on my standard DPI monitor with Chrome/Win11 (100%) that it's very distracting.

That 1MB is the full resolution image you open in another tab.
innocenat··on Dell XPS 13 Plus developer edition: Now available with Ubuntu 22.04 LTS
Dell claimed that physical keyboard is too thick to put in enough cooling for 28W Alder Lake-P chip in thin-and-light form factor. The touchbar is much thinner allowing more room for the heat spreader.

Having seen benchmark number from XPS 13 Plus compared with other notebook equipped with Alder Lake-P, it looks like it's working.

Email I wanted to use as a login is a totally be a different email than what I wanted to forward to.

There's AirGuard app on Android that will similarly check for AirTags.
innocenat··on Retirement of Amazon MOBI eBook file format
I heard that it's because Amazon don't want to use WebKit for HTML rendering. AZW3 is mostly EPUB in different package.

Don't quote me on this though.

innocenat··on Retirement of Amazon MOBI eBook file format
Dropbox is only available on Kobo Forma, Sage, and Elipsa. It isn't available in more popular Libra 2 or Aura HD.
innocenat··on Retirement of Amazon MOBI eBook file format
That process has been being done with AZW3 for a long, long time already. It's not related.
innocenat··on Retirement of Amazon MOBI eBook file format
Kobo doesn't have wireless sync for third party book. That's a killing feature for many people on Kindle.

> What about battery replacement?

I don't think any e-readers are designed to be user-replaceable except the very first Kindle. As for DIY replacement, I don't really know, sorry.

> A replacement battery manufactured shortly after the reader is going to be as bad as the one that came installed by the time I need it.

Is it? I was under impression that battery mostly degrade with cycle count. At least, there are plenty of people still use Kindle from 10 years ago.

> [...] warranty replacement is a solution.

Then I think you are mostly limited to Kindle or Kobo. Most other e-reader or e-ink tablet are mostly shipped from China so warranty and replacement are going to not be as good.

AFAIK iOS Kindle App can't read AZW3. It's converted to AZK. Amazon probably don't have AZW3->AZK pipeline.
innocenat··on Retirement of Amazon MOBI eBook file format
EPUB3, yes. I don't think I have seen any EPUB2 having problem (except if it's missing encoding declaration)
innocenat··on Retirement of Amazon MOBI eBook file format
Kindle Paperwhite (2021) is one of the fastest E-reader available right now (in term of responsive ness). Kindle device have excellent dictionary too, especially for non-latin language. (Japanese dictionary implementation on Kobo is not very good).

Kobo is more open and is price competitively with Kindle. It's also much more customizable if you are into that.

There are also a lot of Android e-ink tablet like BOOX. These are more expensive but a much, much more customizable as it's basically an Android reader.

Contrast shouldn't be a problem with any recent device. But anything release in past 1-2 years are excellent.

innocenat··on Retirement of Amazon MOBI eBook file format
Probably because the EPUB file has some problem. Amazon is very strict about EPUB validity.
innocenat··on Retirement of Amazon MOBI eBook file format
The CLI is still shipped with Kindle Previewer 3 software. It's still used internally by Amazon.
innocenat··on How fast is 12th Gen Intel Core?
Gen 12 machine with low heat is an exception rather than the norm sadly. It must be possible, since there are a few machine out there that manage to do it, but most machines right now are quite hot and has low battery life (compared to 11th gen), especially the P-series in thin-and-light form factor (I am writing this comment from Lenovo X1 Carbon Gen 10 with 1280P, which can't even match the Cinebench score of the frame.work)
innocenat··on Standard Ebooks
> This is perfectly readable even on a small phone screen, in landscape orientation and without margins.

That's a lot of condition to be perfectly readable.

EPUB is readable even without all those conditions because it's reflowable.

(And personally I hate using landscape mode on my phone/Kindle)

innocenat··on Standard Ebooks
I guess you don't read on smaller device. Kindle, for example, with 6-7" screen, is not going to read A4-formatted PDF well at all. On phone, too. A4-sized PDF only works well on 10" device or larger.
innocenat··on Does a compiler use all x86 instructions? (2016)
Maybe I was not clear. The problem is that no one is going to agree to the same definition.

I have already listed several points where disagreements may occurs, and that is just the surface of the complexity.

innocenat··on Does a compiler use all x86 instructions? (2016)
That's a big "if".

We can't even get a single assembly syntax, and Intel vs GNU/AT&T syntax war is almost as bad as vi/emac.

innocenat··on Does a compiler use all x86 instructions? (2016)
ffmpeg and other multimedia library are full of handwritten assembly and C/C++ with intrinsics function. Most math/scientific libraries too.

They also usually contain macro to generate code for multiple variations of instruction sets (SSE2, SSE3, SSE4, AVX, AVX2 at least, maybe more).

Shuffle and Unpack are very, very common in multimedia code.

Isn't like REP MOV the only thing useful in application code? I think it's special cased in CPU to use whatever available to copy as fast as possible.
