LOC is far, far from a perfect measure of productivity, but ultimately if you do want to be shipping plenty of customer value (and/or tech debt reduction), it does take plenty of code to do so. Sometimes there’s 10 LOC which huge value

It is worth noting there are good options out there to get both compile time type safety and runtime validation using TypeScript. Personally I’m a fan of ts-rest: https://ts-rest.com/ Write a specification of your endpoints

Well that was extremely suspicious. New thread, on the first page of HN, getting tonnes of comments very quickly. Almost all of them very negative about Airbnb, a HN company, and then the thread magically disappears from the front page? Wen

I used to be a big fan of Airbnb, but have gone back to hotels. Cost is one thing, but honestly, the entire Airbnb experience is shit now: - Used to be very personal/unique. You’d stay in someone’s house while they were camping/wh

Yeah agreed, I worded that poorly, there’s always multiple causes. Both logging and fire suppression are significant causes too. It is worth noting, though: - That paper cuts off at 2017. Things have gotten even worse recently: the previous

Depends where you live. I live in Vancouver, BC, and the effects here are very, very significant. It used to be that wildfire smoke in the city was super rare, but for the past ~10 years there’s been massive amounts of smoke in the city alm

Seems highly unlikely Dave Clark was a double agent installed by Amazon. Flexport only compete with a small part of Amazon, specifically Fulfilment by Amazon - hard to see them risking the massive blowback if discovered just to take down a

There are legit security researchers out there, doing good work and finding real issues, but the vast, vast majority are … not that. If you open a security bug bounty program, for example, you’ll mostly get either auto-generated garbage lik

I do think it’s a form of overfitting - loss on the training set improved while loss on the validation set got worse. However, it’s not the common form of overfitting, where accuracy on the validation set gets worse. In this case, accurac

Fingers crossed that both regulators and the general public can differentiate between very good tech rolled out very carefully (like Waymo, or to a lesser extent Cruise) and very buggy tech rolled out very recklessly (like Tesla FSD). Hard

You have to be absolutely insane to beta test Tesla FSD, it’s very dangerous and full of bugs, nowhere close to ready. The only reason it’s out on public roads is because Musk is in charge, and he’s happy to take massive risks and kill peop

I agree, and I’m extremely far from a free speech absolutist - to a level that I’m sure most at HN would disagree with. I completely believe in limits to free speech on a case by case basis, online and otherwise. For example, I think HN wou

Go’s decision to not support function overloading leads to a tonne of really ugly APIs. Obviously every decision in language design is a tradeoff, but IMO they made the wrong call here.

Ooh ty, will give that article a read! And yeah, that's really the trick to queries that are consistently fast, even with cold caches - read few pages :)

by yashap 3y ago
Yeah, I believe which order is best (sortKey/filterKey or filterKey/sortKey) really depends on the specific data/queries, best to try both and pick the best one - looks like sortKey/filterKey in this case :) But I think

Lots of replies to this one! I created a little benchmark that you can easily run yourself, as long as you have Docker installed. It shows how, for cases like the one I described above, the only way to have consistently fast queries (i.e. e

First off, ty for running all these benchmarks, above and beyond! FWIW, I don’t think joins are bad, I’m 100% for normalized DB schemas with joins. But I’ve done tonnes of performance work over the past ~10 years, and run into a bunch of re

Ty for benchmarking, but this isn’t a good benchmark for the issue I’m talking about. This is only fast because 100% of users have a phone number as a primary contact, so the join filter is essentially meaningless. If in the contact table,
