People who get this should donate their excess bandwidth to a "worthy" cause. For example e-hentai.org serve their images from a p2p system called hentai@home and their total netwo…

CAPTCHA isn't just a matter of protecting your site. One of the most evil attacks nowadays is "Distributed Spam Distraction", where you spam your victim with thousands of emails pe…

Yea someone else also mentioned that generalization (called a tiered vector) in that thread: https://news.ycombinator.com/item?id=20873110

Express Helmet also turns it off by default and included a rationale for why (tldr: privacy leaks when there are random external links posted on a page): https://helmetjs.github.io…

There was a really interesting post on this topic recently where you have a circular array of circular arrays of size sqrt(n). [1] The result is you can do O(1) access, O(sqrt(N)) …

I think people are supposed to report their salary with the stock price at grant, not after appreciation (at least on levels.fyi). But yea it's a lot more because google stock is h…

It's no secret that content moderators moderate content. Most of the stuff on HN is shaped by a few people who gets to decide what's interesting enough to get a boost or not. It de…

It wouldn't help if new features extend the capabilities of existing stuff (which is done all the time). For example the CSS Shader example from before adds new syntax to the exist…

I am always irrationally(?) scared of using these sanitizers despite their successful history. As soon as new html/js/css syntax/features are introduced, won't your security model …

(We're getting way off topic) but I think the problem with auto increment is that it can't be sharded easily since multiple shards can increment to the same value. If you then try …

I am trying this out and I am still on the edge of whether I like it or not. Create a table with a json column: CREATE TABLE Doc ( id UUID PRIMARY KEY, val JSONB NOT NULL ); Then l…

Technical note: big oh isn't a useful measure here. Most databases use b-trees (yes, even mongo) so lookups are at best O(log(n)). That goes for you and the people replying too. Th…

I think we're way past that point already. Everyone with a phone already has their location tracked at least by their phone company. You might've even given it away to other compan…

I didn't believe that number but it seems like it's true if you restrict it to just north america monthly active users: https://thespring.io/investing/facebook-makes-more-revenue-p…

The two communities have surprisingly different cultures (despite having high content overlap).

I have recently been struggling with versioning(and learning devops in general) myself so I would love to hear more on this topic. For example if you rollback a deployment (or if y…

It's sad that you're getting downvoted. I was trying this out on my phone and although I had to switch to landscape to make the UI fit, it was buttery smooth! I was really impresse…

Figma is pretty successful and is written in C++ compiled to webassembly: https://www.figma.com/blog/building-a-professional-design-to... https://www.figma.com/blog/webassembly-cut…

I don't work with webgl much but I remember there being a max texture size of around 2048 or 4096 on many devices. Wouldn't you end up needing to tile the texture and stuff?

Machine learning researchers aren't working on language modeling because they want to enable fake news. They are working on it because it improves all downstream NLP tasks. See: ht…
