New comment by username3 in "Why tail-recursive functions are loops"

username3 — Mon, 11 Aug 2025 22:23:39 +0000

> I wrote up a detailed blog post about tail call optimization in Elixir/Erlang and its performance. The TLDR; sort of is that none tail call optimized recursive functions (body-recursive) can be faster and more memory efficient than TCO functions. This is something that I never thought before, that TCO is always faster seems to be a common misconception. My example is also not contrived - it’s an implementation of map.

You should see what Elixir is doing with Tidewave and usage rules.

Add an attribute to a model, run `mix ash.codegen`, it creates migrations for you.

Ash can do paging for you.

You don’t need to create a context file with CRUD functions for your Repo.

See the example repository for the Ash book.

Would anyone care if he just used a shorter bat that didn’t get thinner?

Are there any terminal UI frameworks for the web? I want to navigate my web app with a keyboard.

Ask HN: What is the state of private exploits?

username3 — Thu, 29 Aug 2024 05:27:35 +0000

How many zero day exploits are available to private groups? How many private groups are there? What is the ratio like now? I’m looking for a general idea how exploits are shared these days.

I want to know how likely an average person could pay a private group to target another average person’s up-to-date iPhone or computer.

My mental model has been script kiddies have known exploits. They are the last to get exploits. They cannot get into updated devices.

Rich private groups, state actors and NSA have all the zero day exploits and they wouldn’t waste it on normal people.

Private groups for hire have their own exploits or privately share with other groups.

Do you plan to add custom labels?

Let’s say we ask a question to a politician and they ignore it.

Can we label the question as unanswered, so clients will remind users the question is unanswered?

> As early as 2011, a Google engineer revealed he had been working on a tool to Google someone’s face and bring up other online photos of them. Months later, Google’s chairman, Eric Schmidt, said in an onstage interview that Google “built that technology, and we withheld it.” “As far as I know, it’s the only technology that Google built and, after looking at it, we decided to stop,” Mr. Schmidt

Didn’t America have churches before tax exempt laws? Tax laws came later. Your problem is with taxes and government spending. Remove taxes churches are exempt from and raise sales tax.
