Typical red LEDs used for displays have a peak emission somewhere in 600-650nm range, but it's bell curvish so yeah you can expect a small amount of 670nm light out of it. Does getting exact 670nm light matter? It's just the wavel

It's sign that your VPN works:) Unfortunately that's the price to pay for anonymity today. Go to another website? DDG instead of google.

GPUs are too slow for HFT trading, yes. Deep neural networks in general do work in this domain, people do use them, but the stuff that you can profitably deploy into production is not going to be your vanilla garden variety neural networks,

Really depends on time horizon you're talking about. They actually work pretty well for HFT, there's plenty of data around, and most of the information is just in market data - no nasty low frequency stuff to deal with like news,

Why not both? Linear models for absolute lowest tick-to-trade latency doesn't preclude you from using fancier stuff at earlier modelling steps. Final linear models you ship to fpga can be mere distillations/triggers

Amazon is worst payer among them in the US as well. Facebook and Google pay decent money in London and Zurich, almost on par with US in the latter, London is maybe ~30% less. > How much are you left with now, ~1% of the total tech jobs?

The author is spot on. You just happened to be working for the scrappiest/shittiest faang that's all. Shop around, there is decent money to be made in Europe - but of course it's not as easy to walk into it as in the US today

Exactly. If you're in tech, you should be shooting first of all for $500k TC today than $500k pnl, the former is way easier (luck aspect aside). No point in thinking about active investing until you have like 7 figures of own capital t

Put spare money every now and then into VOO or VT or similar and forget. No knowledge needed and time investment is like a few minutes of your time a month/quarter/year. Squeezing more alpha than that and not losing it, properly d

wat? Google used clicks ("navboost") since approximately forever, it's one of strongest signals for all major web search engines. I guess the better question is why they don't optimize ranking directly on clicks, why sti

Steadily losing 0.5-1kg/month just by cutting out carbs and sugar. Not really full keto (which requires like 70-80%+ calories from fat to maintain ketosis), just paying attention to nutrition facts, stopped buying high carb food, start

Not flaky at all. 10M+ LOC monorepo with a few hundred devs here. All it takes is a fast build system. Full clean rebuild for me is a few minutes tops (distributed on a shared cluster), incremental is O(seconds) - mostly linker. Precommit c

You are grossly underpaid, even for eastern europe. Guys just across the border (or two) from you make 2x+ more, while paying next to nothing in taxes (5% I've heard, as faux contractors) and enjoying some of lowest CoL in europe - ht

Still pretty useful in high noise/signal regime. Though at my last two gigs in this area they were kind of obsoleted in favor of generalized additive models which are more interpretable, robust and have more powerful fitters e.g. moder

Kind of, I've seen some non-public Intel SKUs in the fleet but afaik they just had tweaked core counts and clocks for better perf/watt. They were also exploring non-intel architectures at some point, ppc especially but no signific

Yes, you can explicitly set up additional aliases that will bounce incoming mail (or redirect it). It's an option in "New Alias" screen - "Reject (bounce) all mail sent to this address (disable the alias)". While ev

What's the benefit of running own server in this case? Wildcard aliases is actually a standard fastmail feature, I use it a lot. No per-email setup needed whatsoever, I just give out <whatever>@mydomain.com, they all will reach m

Sounds normal. I had experience with Google - they would categorically refuse to uplevel on transfers (except maybe across ladders e.g. PM<->SWE) and reneg on pay (mostly 'cause you have zero leverage in this position). They have

Right, Google actually has a 'no jerks' policy and values being a good team player more than pure technical brilliance. Being a good engineer gets you L4 (mid) or low L5 level at Google. Growing beyond that is mostly about soft sk

Exactly. Click = upvote. Returning to SERP after a short dwell time = downvote. It's noisy but because you can mine such things implicitly by just logging user's behavior, the volume of data is way bigger than what an explicit fee

Whereas OPT not being lottery-based is 100%, no? And more importantly, you can pretty much go work wherever you want with it, every tech firm is ok with it, but relatively few bother with H1B today for overseas candidates.
