Yes, lock-free datastructures are most useful in real-time contexts where you simply cannot ever block, for example real-time audio.

Doing this today is actually way, way easier than it would have been back then. Today we have a wealth of information and much better tooling (QEMU alone makes the process of writing an OS so much easier). Writing a simple OS and compiler a

The space laser is certainly more outlandish, but both are fundamentally the same. They both posit (contra all the available evidence!) that sinister forces are behind something in the world that you feel has gone wrong.

"Market manipulation" is what we call it when you affect markets illegally. If it's not illegal, it's not manipulation. For example, if I buy a bunch of stock in a company it will usually raise the stock price. That affe

Market manipulation is not anything that "affects the market." That definition would cover pretty much any and all behavior. In this case Discord is not trading securities, is not telling any one else to trade securities, has noth

Not surprisingly, software engineers think that the only thing going on with a company like Uber is software engineering. Which is way more complex and requires way more people than it is frequently given credit for. (Uber isn't just a

That's not true at all. Tons of people in Bay Area/NYC/Seattle are making $500k+ just for being relatively good at their jobs at a company that values software engineers. That's a typical Staff+ comp at a FAANG or simila

"Finding cycles" is not really the problem a GC is trying to solve. It's trying to find all of the non-reachable data, across a possibly cyclic graph. It just has to ensure that it doesn't loop infinitely while traversin

The simplest way to do this is to use the low bit of the address (so long as you align your memory to at least 2 bytes this is fine as all addresses will end in 0) as a marker for whether you've already visited that pointer. See https

I'm not saying there wasn't excitement about AVs. The specific claim I'm disputing (which I've heard over and over again over the past few years) is that either company considered AVs to be the only path to profitability

If there are competitors (e.g., Waymo) that have self-driving that's significantly cheaper, then Uber and Lyft can't compete. So it's a huge potential threat to their businesses. And if self-driving makes rides much cheaper

No, that was never the strategy, no matter how many times people on HN claimed it was. Both Uber and Lyft are aiming for profitability next year with human drivers. (Disclaimer, I work for Lyft but this has been said in public many, many ti

Laptop cameras are terrible because they are embedded in screens, and laptop screens are very thin. It's a physics issue, not a cost one. The Surface can have a better camera because the screen is the thick part (although this makes it

Yeah, had the same experience at a previous company. It's very frustrating that your transparency gets used against you by unscrupulous competitors.

My experience (went to a small liberal school that nobody recruits at) is that it makes things easier for your first job, but doesn't matter at all after that. Even then, grads from my college end up at Google/Apple/Facebook

Indeed. Big tech actually provides both more money and better work-life balance than your typical startup. I think the main tradeoff is that it's more "corporate," but that will depend in large part on your team.

Blind self-selects for the worst of these attitudes (in addition to the general shittiness of almost any anonymous community). I would not take this as representative of SV. The private forum for my company is amazingly toxic.

I used to struggle with this too. What helped me get over it is realizing that this is completely backwards. At every company I've worked for there has been a near-constant need for good people. When a former colleague who I know does

At least on violin the different strings have slightly different timbres, as do different fingerings. Playing a G4 as 3rd finger on the D string will not sound the same as playing it in third position on the G string even with very precise

This is a bummer. I gather that I'm one of the few users of Google Play Music, so it's not surprising it's being killed. But it was one of the few streaming services that had the ability to upload your own music, a good catal

I think it's not so cut-and-dry. As a violinist, I can recognize absolute violin pitches, but can't do so with other instruments. This is definitely a learned skill; presumably there's something about the timbre of the differ

You're talking about relative pitch, not perfect (absolute) pitch. Any competent musician will have excellent relative pitch, which is the ability to recognize intervals between pitches. This is necessary for transcription, learning mu

An issue with this is that it's inherently one-sided: you get to see the performance of the people you hire, but you have no idea what happens with the people you reject. Because of that, you inevitably get "weird" results li
