Agree completely. This is one of the worst things you can do, even if the code isn't particularly confidential. It is such an easy case to win. Worse yet, you expose your new employer to enormous liability and can taint their entire co

Talmud scholarship in general is an important part of some Jewish people's culture. They have a rich history of debating rules/their interpretations and applying them to hypothetical or actual life situations. It's a great wa

Sounds similar in operation to a Shabbat Elevator ( https://en.wikipedia.org/wiki/Shabbat_elevator ) which visit every floor automatically, but still have traditional doors and don't run on a looped circuit. The deb

Are men more accepting of high risk, low QOL careers? You don't see many women on oil rigs or driving long-haul trucks, either, even though it can be quite lucrative relative to the skill level required. Software jobs have little in th

Possibly has to do with wealth? When you have little, you have to prioritize finding a job that pays as much as you can possibly make. STEM jobs top that list easily. If you have a lot, pursuing a more leisurely or personally rewarding job

FreeBSD's new CoC wouldn't ban a sexist comment like this, because of the odd "oppressed group" language. Hopefully it was just a copy/paste mistake from the Geek Feminism code. There's no place in a software p

You're both right. There are traders who beat the market in a way that's clearly statistically significant and doesn't involve selling tail risk or other cheats. However, they can stop being successful at any time. To give a

I think it's a case of bad optics. Most leveraged ETFs or ETFs that hold futures and constantly pay roll costs just slowly decay. They're not suitable for the average mom & pop, but holders have ample time to see their investm

Awesome post and your meta-analysis rings true even on tiny time horizons. Years ago I traded energy futures and we hired someone away from a rival. He knew a trick for seeing crude oil price changes on CME a few milliseconds before they se

Please read the prospectus for these products. Leveraged ETFs aren't appropriate for long term hedging.

Not sure what you mean by splitting pennies, earning the bid/offer spread? That's common but the person who paid the spread to them got to trade instantly instead of waiting for another natural buyer or seller. The spread is payme

I would agree with you 99% of the time, but not for these products. Professional fund managers who want to insure against volatility can easily trade VIX futures or index options. They wouldn't use an ETP that can only replicate daily

Why's it a waste? Low latency traders facilitate risk transfer in thousands of instruments at razor thin margins using automation. They keep prices efficient through arbitrage or predictive modeling. Even during extreme market stress I

Depends on competition. Suppose you pay $300k a year in SF and the guy/gal in India's next best alternative is working for a local company making $50k which pays for a very nice lifestyle there. If you pay $100k, you're still

I think the continuous price/time priority limit order book is flawed, but the least bad option out there, similar to democracy. Speed will still matter in batch auctions if other continuous exchanges trade correlated products--the onl

You need to prioritize orders in the market by some objective metric. You want a metric that rewards good behavior and punishes behaviors you don't want, for the market as a whole, not just any one participant. Almost all markets now p

Depends how you mean exploit. Not a lawyer, but to a first approximation, doing anything in markets to elicit a response from others rather than for bona fide economic reasons is illegal market manipulation so active exploitation is rarely

Merely anecdotal, but I've run heavy multi-threaded compile tests on my 1950x for days to check whether the chip was stable when overclocked, and have never seen it segfault. That was my main purpose for purchasing the CPU. I use it fo

Laptop RMAs are way more expensive since they have to swap the entire board w/CPU or reflow solder on a new chip. Can't imagine any OEM will willingly take that hit. Since these issues are well known, I'd bet AMD has to fix t

Didn't know that. Since they know how to fix it on TR/Epyc, why would they release a brand new line with the same issue?

Does this exist on Epyc platforms that don't use a traditional chipset? This is bad, but seems like more of an incremental issue than anything. Can you audit every line of source in your system? No closed source drivers or firmware on
