Same can be said about loopback device in general. Why do you need to use networking when you are literally on the same device and can use binder/dbus and friends with native apps?

Shizuku uses Binder AFAICS[^1]. Looking deeper it seems that Shizuku does not connect to the device itself per se, but rather it has a privileged server launched manually through adb. Never used Shizuku, so can't say for sure.

Arguably PCIe lanes the thunderbolt exposes are a differentiating factor, not the maxed-out specs that "plain" usb-c cables can have. Although to be fair, I've never used the PCIe lanes on thunderbolt ports.

Sort of, there're more posts about graphene in the year 2026 & they get much more attention. Aggregated some data and plotted it with my agent: https://boop.icu/Pr.png

That's what I wondered as well, whether it is a new implementation, or perhaps they still use their version of cups? Or maybe they use the forked openprinting cups? Would be nice if somebody knowledgeable with a mac device told whether the cups is still used

The repo got archived in march, I wonder whether it means that Apple uses something other than CUPS on their devices? Quick search suggests they still use CUPS, but why would they archive the project then?

Both are non-deterministic, both have some metric to optimise, one is specific and efficient, the other is too broad and very expensive

Much older? Wikipedia says[^1][^2] java appeared in 1995 (started in 1991), while python appeared in 1991 (started in late 1980s). 4 years doesn't seem too far apart, considering both language are >30 years old now.

He doesn't have a role at Facebook anymore AFAIK, although I can't find the source now. I remember hearing it was mostly due to filtering engine at Facebook being rewritten in Hack, so they don't have the need for Haskell people anymore.

Secure boot ensures the image you boot was not tampered with. You can't install keylogger without tampering with the image. If you wanted to install physical keylogger, you would need to open the device up, and at least my laptop provides detection of bottom cover removal, meaning the system will ask you for a bios password if the laptop was opened up.

> you don't have a colourblind person's 'profile'

Why not? As far as my understanding of color blindness goes, you just need to find a precise transformation matrix and offsets to be able to correct any type of deficiency (except for achromatopsia, I guess).

> When I use them I find the colour profile I am used to in the wider world flipped, and the semantic meanings given to colours, or their hierarchies, completely changed.

I think the correction applied to digital content is a positive thing. At once you can perceive color the way it was intended to be perceived. May be wrong here because I don't have daltonism.

> You can try to make a perfect system for every variation but the end user won't see it as precisely as you intend.

My goal is not cover every case, but to create exactly one profile (and perhaps create a usable correction workflow for someone else)

Thanks for an elaborate response :)

Ask HN: How do you deal with color blindness?

qrobit — Thu, 07 May 2026 13:42:19 +0000

Hello, I am interested in how do technical folks deal with color blindness problems when using screens? Especially those of you who have rarer variations of it.

There are some color correction options in OSes and games, but they do not cover the full spectrum of color blindness.

One current solution I am investigating is using ICC profiles to perform correction, perhaps you can tell me whether this is feasible/efficient.

There should still be privacy concerns, especially with their demo which sends a POST on "Generate". The author suggests the model is 85kB of weights, which could run perfectly well in browser.

> But with this software - the tolerances are looser, so the clothing becomes more manufacturable.

Does it? How do looser measurements help? I assume manufacturer would always take the upper bound of dimensions. Suppose model also predicted your dimensions are higher then they really are, so these two in combination give you an oversized piece of clothing.

Just a reminder that even if you managed to amend those commits and force-push, the commits would still exist and will be addressable given the hash is known.

Hackage recommends using Haskell's PVP[^1], but does not enforce it. That's why many haskell packages are a four-places versions: 3 required and fourth optional (but popular) that represents "other" changes, like documentation.
