orangea — Tue, 11 Aug 2026 17:41:57 +0000

It's because it's effectively impossible to make a markdown authoring app that meets everyone's needs, and people tend to be picky about what they want in a writing environment. People have strong preferences about WYSIWYG, flavor of markdown (pandoc/quarto/GFM/etc), theming support, some want notes to be able to link to each other, etc. As an example, I require math notation support for basically everything I write which automatically rules out 90% of markdown editors for me.

It probably has more to do with the fact that formalizing chess in such a way wouldn't be particularly interesting. Chess is mostly studied because of its historical significance, and if you change the rules then the game no longer is as connected to its historical significance.

I mean... is it not obvious that in a he said she said scenario like this they have to simply side with the buyer? I struggle to understand your mentality, assuming that you have no way to prove (to Amazon or to a court or whatever) that their negative feedback was fraudulent.

New comment by orangea in "Let's discuss sandbox isolation"

orangea — Sat, 28 Feb 2026 01:39:04 +0000

The first half of the article says "namespaces, cgroups, and seccomp aren't 'security boundaries' because if the kernel had a bug it could be used to escape from a sandbox". Then in the second half it says "use gvisor and do all this other stuff to avoid these problems." This presentation feels kind of dishonest to me because the article avoids acknowledging the obvious question: "well what if gvisor has a bug then?" I mean, sure, another layer of sandboxing that is simpler than the other layers probably increases security, but let's not pretend like these are fundamentally different approaches.

If the successful people you meet in real life are nice and you see lots of meanness on the internet, it probably just means that anonymity causes meanness.

I don't think you meant "ostensibly".

Learning homological algebra is a long way away from learning about varieties and ideals in any sensible order in which to learn material. You have to do a lot of work in between in order for homological algebra to seem motivated. Sounds like you ought to try an introduction to algebraic topology.

> Well, dhh considers torrents outdated (I’m not kidding, check the tweet), so it’s only officially being offered as a single download from a Cloudflare server. Which sounds cool until you’re on a weak-ass connection in constant danger of dropping halfway through the download.

That has nothing to do with bittorrent vs http; use a download manager instead of a browser.

Asahi is useless to me, and I would assume many others, without USB-C display support.

Don't you think that the vast majority of dangerous human drivers would be perfectly capable of changing their behavior during a driving test? Even without any malicious intent most people would be more careful during a test.

> targeted specifically high ticket items (jewelry, luxury)

My immediate instinct upon reading this is "of course those businesses wouldn't be interested". They are selling a brand and image first, and if it looked like they wanted people to download some new app and put in their bank details to make a purchase instead of swiping a credit card it would cheapen the brand. Luxury stores are all about a streamlined experience and the appearance that money is no issue.

At least this is a topic that the average HN reader is likely to be able to understand and which is closely related to software. Several years ago there was a period where there were periodic posts about things like homotopy type theory and research-level algebraic geometry which inevitably spark only inane misunderstandings and uninformed speculation in the comments. I can only attribute it to some kind of fetish for the frontiers of pure math.

When something costs $1/year, the primary barrier isn't being able to afford it, but having a valid payment method. Depending on the requirements, it can be an issue if you don't have a credit card, don't have a bank account, etc. And not having those things is slightly correlated with poverty. In addition, it makes it harder for children to sign up (not necessarily a bad thing, just saying).

- Doesn't allow installing multiple versions of packages at the same time

- In practice, requires being installed to /usr/local

- Hard to uninstall in practice, leaves files scattered behind

On the other hand, the F key has a bump on it on every keyboard I've recently come into contact with, which could provide an anchor.

I suppose with ESDF you have the two keys Q and W where otherwise only tab would be.

You could also just find a way to rebind caps lock, which would accomplish more or less the same thing.

> Another bought a laptop by taking out a stablecoin loan on a DeFi platform when no bank would lend to him.

Could someone explain this to me — I thought that loans on cryptocurrency platforms had to be collateralized by cryptocurrency? How could someone buy a house with a crypto loan if they didn’t already have enough to buy one in the first place?
