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.

Mostly true, but I personally have it turned of for duckduckgo and it shows me some ads with [ad] label. Actually if you wanted to disable ads there, you wouldn't even need an ad blocker, there's toggle in the settings

I was surprised not to find cantata[1], another MPD graphical client, on the list. Used it for the past three years, despite it being unmaintained for quite some time now. The client is very featureful, allows downloading lyrics and covers automatically (TBF had many mismatches, like downloading some Gillette ad as an Eminem's album cover). Most important to me is the ability to listen do directories and not artists/albums, which cantata does perfectly. Recently nixpkgs replaced cantata with a fork[2], so cantata is kind of online again.

I wanted to say Haskell with shh[^1] and stack's or nix's shebangs[^2][^3], but interpreted haskell is not particularly fast.

Also I think a Python script is reasonable if you use a type-checker with full type annotations, although they are not a silver bullet. For most scripts I use fish, which is my preferred interactive shell too.

[2]: https://docs.haskellstack.org/en/v3.9.1/topics/scripts/

[3]: https://wiki.nixos.org/wiki/Nix-shell_shebang. On a side note, if you were to use nix's shebang for haskell scripts with dependencies, you should be using https://github.com/tomberek/- instead of impure inputs, because it allows for cached evaluation. I personally cloned the repo to my personal gitlab account, since it's small and should never change

I would argue that the barrier to entry is on par with python for a person with no experience, but you need much more time with Haskell to become proficient in it. In python, on the other hand, you can learn the basics and these will get you pretty far

I think smalltalks just didn't bring you to the right topic, if you were to reach topic you both fancy, you would definitely remember each other. If anything, having a smalltalk is nicer than staying in awkward silence.

Unless there is some vulnerability in the current version that you want to take advantage of. See e.g. mediatek exploit to unlock bootloaders without authorization by OEM or hacking PS4.
