Elasticsearch and OpenSearch already support S3 backed indices. See features like https://opensearch.org/docs/latest/tuning-your-cluster/avail... The files in S3 are plain old Lucene segment files (just wrapped in OpenSearch snapshots which provide a way to track metadata around those files).


But you don’t have fast search on those files stored on object storage.


Yes, there is a cold start penalty but once the data is cached, it is equivalent to disk backed indices. There is also active work being done to improve the performance, example https://github.com/opensearch-project/OpenSearch/issues/1380...


Blue Origin is not part of Amazon.


Ok technically yes, but their IP is probably shared.

For instance, Elon Musk has mentioned the Materials Science team he has works for all 3 companies Tesla,SpaceX,BoringCompany etc...


There are close Google <=> SpaceX links too... The Starlink backbone network uses Google Cloud features that appear custom built/aren't available even to big customers. Nearly all Tesla tech seems built on top of Google tech - for example they use various private maps API's for the in-car map display. And everything is built on top of protocol buffers, google's in-house RPC/serialization format.


Protocol buffers have been public for 10+ years (since 2008 according to Wikipedia). Given the mobility between tech companies, it's hardly surprising that the same ideas / solutions are reused across companies.


Some features that Betterment offers for example

* automatic rebalancing

* tax loss harvesting

* tax co-ordinated investing - looks at both your taxable and tax exempt/deffered accounts and directs funds appropriately (for example, puts more tax inefficient assets in your tax exempt accounts)

You can of course do this on your own as well, so it's up to you to decide whether the additional fee is worth it or not. Also, not all robo advisors offer the same features - but most offer automatic rebalancing at a minimum.


Automatic rebalancing is not that useful as long as you're contributing, because that rebalances on its own.

Betterment's tax loss harvesting is good… unless you're expecting your tax rate to go up next year, in which case you want to harvest gains… also, it'd be better to not lose money in the first place. Since they have alternate portfolios like "smart beta" now which try to do that, their features conflict with each other.

The main problem is that every robo uses the same Modern Portfolio Theory based investing which despite being "modern" is from 1960.


As per the landing pages of the projects, ES has 1.6k contributors whereas ClickHouse has 803. The contributors page likely only lists the top contributors to keep the page load time manageable.


That makes much more sense. Thanks for pointing that out.


Yes, there is a base cap of $160K ($185K for HCOL areas like NY and Bay Area), and the rest of the compensation is RSUs. For engineers who are senior and above, RSU based compensation will usually be more than 50% of their overall compensation.

The comments in the original blog post suggests a gap of 60k with the offer. Your comment makes sense only if he was interviewing for a Principal Engineer position or something, but instead was offered an SDE-I position. Plus I'm pretty sure very few (if any) non-Principal SDEs at Amazon actually get 200K in the first year.


Yes. If you can be promoted directly from SDE-I to SDE-II, there should not be a ~60K gap between. I've had the described thing happen (start interview by assuming level 3, but hire at level 2), and the gap is more like 20K. In other words: they should have known better.


In AWS, if anything, it's the other way around. Devs always run their own services at first, and ops teams start helping out once the service reaches some kind of scale where a dedicated ops team makes sense. (source: I work for AWS)


In this case, he did delete the tweet soon after.


Yeah I figured this out once I read the article about it on recode.

I am pretty sure a lot of twitter power users would freak out over this kind of feature. One that integrates something similar to moments, but within the context of your timeline.

But twitter is a global product so when I wake up in the morning in the USA and see something like that apology tweet. I don't want to have to dig to figure out what's going on.


> Once they establish dominance or once the smaller players run out of wall street sponsored discounts, the Amazon offers will also disappear.

My experience as an Amazon customer in the US has been contrary. Amazon is actually one of the rare companies that values loyalty and rewards existing customers. Most other startups (even ones outside e-commerce, like Uber/Ola etc. have offers that aggressively target new customers, but rarely offer anything for existing customers) Compare that to the experience of an Amazon Prime account holder. What started as free 2 day shipping now covers free 2 hour shipping, access to lots of media etc. at no added charge. A majority of the offers and discounts are also made available to all customers, not just new ones. Is this not the case in India?
