You are not entitled to your multi-six figure job, and no one should feel bad for you if the company decides you are an excess. If you are not creating enough value to justify your presence, the company has every right and frankly society s

It's silly to mention the cash on the balance sheet without also mentioning the debt of $77B. In reality, the net cash position is on the order of magnitude of $30B which puts a much tighter perspective on the impact of this cut. 40% o

That's not how I read it. Index funds are conservative, but the author points out a big difference between the optimism + paranoia ideal mindset vs. the conservative mindset. With index funds, you'll never go poor, but you'll

Web programming is incredibly easy in general, and gets even easier every year. Game programming is much harder in my experience. Game Engine programming is not even comparable.

No one needs this much, but lots of people want this much or even a lot more. Some folks have expensive tastes while others are content with reading library books in a cabin in the woods.

Most bitcoin investors never move their coins off the exchange and thus don't have a distinct address on the blockchain, so your sampling technique is probably just as flawed as time of app download, if not more so.

Of course not, because it was pulled from his ass. Google had 120k employees in 2019, and 150k in 2021. Even with churn, the OP is way off

That depends on your alternative options. The S&P 500 has averaged 6.6% real returns historically. Better than bonds? sure. Better than unleveraged global real estate? sure. Better than gold? sure. Better than PE? no. Better than levera

The base problem is that people have expected pensions to pay out like they always did in the past, before the ZIRP era. When real interest rates were positive (like they were for most of history until circa 2010-present), it was very easy

Very interesting, I'm glad to hear you are also building your own models and having success! I'm pretty tight-lipped about the inner-workings of mine, as unlike selling access to the generated signals, sharing details about the in

This is different, no martingale here and no leverage used at all in obtaining the returns, the models are always either hedged (effectively in cash or 0% long) or unhedged (100% long). This is also not a high frequency trading system. Most

Right, but as it mentions there, "Continuous data is from 5-Aug-2008 , Individual contracts start with VXF09 (March 2009)". To calculate the Vix Futures curve, our models need the individual contract intraday breakdown not just th

Healthy skepticism is warranted! I've answered several of these in previous HN comments such as https://news.ycombinator.com/threads?id=pyrrhotech&next=3012... and https://news.ycombinator.com/threa

IMO it's easier and less work to outperform the indices with a combination of passively holding ETFs like VTI / VOO and strategic hedging based on quantitative leading indicators of economic trouble rather than trying to pick indi

Most of them aren't really hiring, but instead using the thread as covert advertisement for brand. In fact, HN largely exists in general to promote YC companies. Why would they allow comments on these threads, of which a large majority

As the Fed has backstopped every drop since 2009 with seemingly endless liquidity, passive investing has been all the rage over the last decade+. Unfortunately, the party is coming to an end soon, and who knows how history will judge the Fe

How do you implement all the things the game engine gives you for free? Physics, camera, scene management, lighting, colliders, shaders, navmesh, etc. It seems like an impossible feat to implement all this yourself PLUS build a game on top.

Though management's questionable shift in focus to the Metaverse over its core apps and spending $10B+ annually on it is certainly largely responsible for the drop, it's also clear the the competition of its core apps is fiercer t

The numbers were pretty bad, big miss on revenue and guidance below analyst expectations. It seems the market was pricing in even worse numbers, given the terrible stock performance over the last quarter and last 18 months. It's really

Highly insightful. The pandemic stimulus isn't the only cause though, more like the icing on the cake. The experimental QE and ZIRP policies probably won't be looked at too kindly 50 years from now when economists are still trying

Thanks for the detailed response, I'll do my best to answer: 1. Internally, the model does work on a sort of weightings / probability system but it's not so simple as boiling down to a single probability figure, i.e. if it hi
