Nothing was stopping the Robinhood customers from opening an eTrade or TD Ameritrade account or something and doing their trading out of that platform for the duration of the outage. Robinhood isn't really an institutional platform in my understanding anyway.
I don't offhand remember AWS increasing prices for a service before but I might be wrong. How often does Google increase prices?

For a business I prefer a company that starts with higher prices and then only lowers them to one that may increase them at any time.
There are two things:

1) Somewhat pedantic: A big reason why performance is-what-it-is is that at any real $$$ liquidity/volume becomes an issue. Lots of option markets are just not that liquid. If you play with only a few $k and robinhood pays for much of market friction then you can potentially outperform market at risk parity.

2) More real: For most people active trading is not about investing, it is about easy and legal gambling. There is a thrill of throwing you money into high risk options or skyrocketing meme-stocks. Because markets are (relatively) efficient the prices of these assets usually reflect their risk profile, so on average you should gain money (flip side of it being hard to beat market is that it is hard to severely underperform, on average, as long as you don't all-in; normally friction cost makes these kind of strategies not work but RH reduces that significantly). It ends up like going to a casino where on average you make a bit of money (but with high volatility means some people lose a lot, some people gain a lot).
I totally agree with you.

>china and south korea both explicitly stated that they were transitioning to wartime footing to combat the virus. we need to follow in their footsteps. we need billions of dollars in spending, suspension of normal daily life, and requisitioning of the necessary resources from private entities if needed. and we need to do this today. now. this afternoon. preferably before 5 PM. this isn't a problem to be left until tomorrow.

This won't happen in North America. As a Chinese who reads Chinese and English news sources everyday, it appears while China is very heavy handed in censorship for anything coronavirus related, in NA there is too much misinformation floating around, to the point that people cannot agree on anything. Specifically western media have been producing outrage porn for clicks around Covid 19 for a while, resulting in much misinformation on how China's measurements in combatting the virus are inhumane and in violation of human rights, that even talking about those options will bring so much negativity into the discussion. Apparently inaction and incapability of the government and every one only takes care of themselves are not human right violation.

Even we don't have a cure, slowing down the spread is a huge win in for the healthcare system as a whole.[1]

I'm interested now that PowerShell is cross platform. For someone reasonably fluent in bash/zsh (and Python, etc.) already, could someone give examples of where they might use PowerShell?

http://nushell.sh/ is an example of a new (non-POSIX) shell that's trying to be more structured, similar to PowerShell. Thanks to nu's new -c option, it's possible to use nu profitably even if you don't make it your shell. I doubt I'd ever use PowerShell as my system shell on Mac/Linux, but I don't want to close myself off from tools that might be useful for particular tasks or scripts.

I imagine healthy companies keep enough manufacturing parts to be able to repair/replace/scale as needed. Particularly a company like tesla which is well known for scaling rapidly.

like, for example, if the vaccine is made from chicken eggs and a non-sterile batch gets through because we scaled up the pipelines faster than what was safe...

Yup! I'd highly recommend reading through this link as it is a great literature review of education theory and how it relates to CS Education.
As a side observation: most reporting seems rather binary, i.e. you either die or survive, period. What interests me the most, however, is how often survival means full recovery, especially now that the nervous system comes up. Are there any long term effects? Should one generally expect to come out of it worse, the same, or stronger? I'm much less afraid to die from this than to end up with chronic respiratory and/or neurological issues.

I have to say, I can't understand the author's glee while investigating the bug. To me, bugs are a source of irritation.

This person seems to do it because investigating seems to be a source of joy for them. For me, investigating is a frustrating necessity to fix the bug.
I agree with your point.

Of course an alert system would have to be able to understand all those things. That's why we don't have that kind of system.

A single number in isolation is rarely useful. Graphs with trends are useful. Alerts are useful.

The only reason we don't have alert based speeds is because it can't get all the necessary information to make a useful alert, so we compromise by telling you the number.

A perfect example of why a graph would be ideal here, not a single number.

They specifically said it lead to a DNS failure.

I was wondering the same thing. Nothing comes to mind but there are enough services I don't use that its easily possible something slipped through.

AWS lowering compute costs is fairly largely shared, but I am curious if anyone has compiled a list of the cloud providers (AWS, Azure, and GCC) increasing the costs of services.
If you know how these storage services worked under the hood you would understand that durability is not guaranteed. It is the responsibility of the customer to ensure their data is backed up.
>my "high-interest savings account". Maybe a grand or two over decades

Huh? Either you have very little savings for someone on this site, or your "high-interest" account isn't high-interest. Ally Bank currently has 1.6% interest on their savings account, so you'd make $1000 in interest in 1 year with a balance of about $62k. If your savings account doesn't have at least 1.5% interest, then why do you have it? There's lots of places with rates of 1.5-2%.

I have found that subreddits almost become an anti-expertise forum over time - when actual experts show up to give advice, they are often downvoted if their advice goes against whatever that subreddit is cargo culting (which, as you mentioned, is often not great advice in the first place). Then the expert is discouraged from participating ever again.

I've witnessed this pattern in an array of subreddits spanning from hobbies to coding to gaming. Ultimately they become discussion forums for the lowest common denominator of skillsets.
Different companies make money using different approaches and it's perfectly valid to be upset at the approach a particular company is taking. Just because they provide a service doesn't mean they'll try to f* you over at every chance. For some it's bad long term business to do that.

AWS, for example, begins with high prices and then lowers them over time. It costs money but you know the maximum.

Google seems to be grabbing you with cheap prices and then jacking them up when you're committed (google maps is another example offhand). Maybe no on purpose but bad initial pricing and ill-intent have the same impact externally.
Raw materials are not my concern - the industries that supply them can get all the people they need from others. You might find yourself demoted from programmer to some third shift factory labor job, but with a few weeks training you can do it (with okay odds that you won't lose life/limb from missing some safety item)
On top of providing some limited protection of the wearer, it also works like herd immunity in that if everyone wears them, then those that don’t yet know they’re sick are reducing their spread.

At the moment because of the misinformation people wearing masks are being mocked and chided in public and its really unhelpful. Especially since there are immune compromised individuals and individuals with other conditions that really need to take every precaution they can, including that 10% reduction a surgical mask may give them.

> My point is your article is based on a fake premise, or a poorly designed premise.

That's a strong statement which you should at least try to provide counter-example to support - just saying "you design it wrong" is not enough. I've seen this kind of problem irl left-right-and-center - so I take it there is an issue, and it's not happening because "everybody doing it wrong".

> If one service goes down, they all go down

I believe you don't understand the diagram. Lines are not dependencies, but a way to connect components of different versions into single product. (I.e., you pick either v1 or v2 of each component, and it becomes single product along the lines - it doesn't necessarily mean there is hard dependency).

To my point, I treat whole architecture as a product. I don't necessarily speak about dependencies. Instead, I'm taking general view of this as a math problem - first of all, I establish search space - that is number of available versions to the power of number of microservices.

Then I very much support and want to discuss various ways to reduce this search space via pruning - and what you're talking about is just one of the options how to prune it (by reducing dependencies). But as others pointed (rephrasing in my words), you can apply a greedy algorithm to NP-problem, but first of all understand what the real problem you're dealing with is and second of all realize that your algorithm is greedy - meaning it may have flaws in the edge cases and it's better to be prepared to those.

In your specific case I claim that you can't be completely sure that you actually don't have any interdependency between components - I believe it would be impossible to prove for any system. And again I saw really hard bugs irl coming from those assumptions. Recent example (this is not about microservices - but pls try to solve this case): https://stackoverflow.com/questions/60486853/aws-ecr-uploadi... - Tools in question must be completely independent, but somehow they are not. So assuming something is completely independent is frequently dangerous.
