No math is escaping me. Video is sequential I/O, which hard drives do fine at. Multiple drives is needed under many workloads, but not video.

If you want to do video stuff on a laptop you have room for maybe one extra hard drive. And if you are willing to have an external drive (which isn’t too bad), it’s not going to work to plug several hard drives in and expect to RAID them together.

Secondarily, there are only so many drives you can stuff in a workstation. A lot of compact ones only have a couple slots in them, and not everyone wants a RAID or JBOD controller with a bunch of ports on it just to do a video workflow. And if you have a video surveillance small server or appliance, you might only have a few slots in it (4 is fairly common).

So again, even one or two hard drives is fine for most uses. Not everyone is gonna put a 24 slot JBOD/RAID chassis in to just provide enough storage space for their video surveillance system or whatever.

The Chinese were nearly universally oppressed by Imperial Japan before/during WW2. Later, they nearly universally suffered some level of starvation under the reign of Mao. As far as the oppression Olympics goes, I’d say the Chinese are ahead of the blacks.

Maybe playing oppression Olympics is just a bad idea in general though. I’m not sure.
If you haven't tried it yet give note-taking/keeping a (work) diary a shot. Works well to get stuff out of your head and separates work from the sleep.
RAID0 can't give you a true 2x increase, because reads and writes are constrained to a particular device, and big reads tend to require both drives working together.

RAID1 can give you a 2x increase in reads, but suffers even more than RAID0 when it comes to writes.

Dual actuators, implemented in a straightforward way, can both access the entire drive surface which means they can give you a true 2x increase. Sometimes even better than 2x, because each arm can focus on one side of the disk. For read/write workloads it completely outclasses RAID.
A lot of Europe tried.

It's really hard unless you can control borders. Even if the US locked down for 3 months and got to zero, it could be undone by one group of illegal immigrants crossing the border with COVID.

The US and EU were already pretty well infected before they realized what was happening. Only China, S. Korea, and Australia had major outbreaks that were contained, and even those, the outbreaks were fairly isolated (Wuhan, Shincheonji Church, Melbourne).

Rust's embedded and OS-level capabilities are a big point in its favor, particularly over something like C#.

Let me say something that may reveal my ignorance, but which I'm very happy to be corrected on: for the purpose of writing moderately-sized, everyday programs, I've never needed to understand how computation works theoretically (more abstractly than introductory algorithms and data structures). And that's not because I'm not comfortable with abstraction, or because I don't know how it works theoretically, I just haven't.

Further, the obstacles I face when coding are mostly tightly coupled to the fact that I'm programming on physical hardware – again, nothing to do with the theory of computation. Even in a high-level language like Python, if you program the Sieve of Eratosthenes in a naive way without understanding what's going on under the hood with deleting an element from a list, you're going to have a bad time [0].

To caricature SICP-style instruction a bit, I'm imagining someone learning that recursion is useful (Scheme peeps seem to love it) without also being taught it generally has poor performance characteristics.

Perhaps a better criticism is the mostly useless emphasis on immutable data structures. The example I like to bring up is how Haskell for a long time didn't have a readily-available hash table implementation for completely ideological reasons. No, hash maps are strictly worse, thank you.

Who in the heck thought this would be a good idea? For the record, back when Desk.com existed, I also saw strange session issues that were probably complex and irreproducible race conditions as well.

I am not as paranoid an adult but CJD and Ebola scare the shit of me still.
The survival rate of Covid-19 is higher than both Ebola and anything prion based so Covid-19 doesn't scare me as much.

I will get the shot. Most of my family has already(medical profession). If my parents get Covid-19 they are as good as dead so I will be getting it for their sake also.
> To caricature SICP-style instruction a bit, I'm imagining someone learning that recursion is useful (Scheme peeps seem to love it) without also being taught it generally has poor performance characteristics.

SICP teaches that recursion can have bad performance and how to use it without blowing the stack or wasting time with unnecessary computations. Scheme, the language, requires tail call elimination so compilers will transform tail recursion into something as fast as a conventional loop.
Also, perhaps standardization could play a role. If the Redis / Mongo / etc were standardized by a neutral party, it may make it riskier for big techs to make their on proprietary or incompatible modifications.

Though I guess this doesn't apply too much to postgresql, since any serious RDBMS is much more than just SQL standards compliant.

Writing "racist" makes it easy for people to stop trying to look for meaning in your writing.
I’m not sure what you mean by “real covid” because the epi case definition is the epi case definition.

Here’s a systematic review of many tests for accuracy [0] and they describe how different tests determine sensitivity and they aren’t based on the epi definition. They do stuff like chest X-rays and none of them, that I read, rely on symptoms or any circular case definition.

Here’s the surveillance case definition that CDC puts out from back on April 5 [1] and it’s not meant to be “real covid” for healthcare purposes but used to try to estimate incidence. So I think of it as the most likely to be useful.

The lab test accuracy is closest to “real covid” in that they try to measure whether the disease actually exists and corresponds to the test result. For novel diseases there’s no gold standard so different tests attempt different techniques. I don’t think all these different tests are all politically biased especially since many report pretty bad sensitivity (50%).

The only points this makes me reconsider is the legal right to murder your own children and having criteria for who gets to have children in the first place.
This is also a problem over in Python-land. One of the interesting approaches is automatically generating non-async code from async code by editing out the async annotations (at the source level). The Trio folks call this "bleaching" the code, in reference to the "What color is your function?" blog post https://journal.stuffwithstuff.com/2015/02/01/what-color-is-... complaining about how the common approach to async in JavaScript divides the world into "red" (async) and "blue" (sync) functions that interoperate poorly - you can bleach your code if it's the wrong color.

https://github.com/urllib3/urllib3/issues/1323 is a discussion of this. "Solution: we maintain one copy of the code – the version with async/await annotations – and then a little script maintains the synchronous copy by automatically stripping them out again. It's not beautiful, but as far as I can tell all the alternatives are worse.

https://github.com/python-trio/unasync is the current production implementation of this approach.
There was this question about books on software engineering. https://news.ycombinator.com/item?id=26488944

I appreciate its flat footed approach and systematic method. To me, these are hallmarks of professional engineering practice. There's no attempt to make the problems more interesting by adding complexity or affectations. YMMV.
> It's easy to show crabs can make logic gates - just do it

That's just an artifact of the way we reason about the world. We take as an assumption that induction works for "positive" events (we showed that these crabs can make logic gates) and can't accept the same evidence when it pertains to "negative" events (we showed that crab movements _are not_ uniformly random -- no you didn't; what if you didn't feed the crabs the right kind of peanut butter?).

That is where my head is at on this too.

I am not worried about the relationship play. I believe that is all this is right now. And she is right in the pocket on that with imaginary friends that are well developed. She is active, but not abnormal from what I can tell.

And the pandemic is hard for those of us who rate on the social axis. She does, and all that is just coping, adapting, getting through a hard time.

However, Siri does not convey being unreal.

I am a little troubled by that.

But, I also need to hear those exchanges and will need to catch them in context too.

On that point, OK Google is a prompt, and one that is also not a common form of address people would use regularly, though it does all get said and done that way. I need to ask some variations on real/unreal too.

Siri is a more full overlap. If I may coin a term, Siri has an ambiguity bias factor much higher than OK Google does.
There is some threshold below which contact tracing and isolation work. A few dozen infected people crossing the border could be dealt with.

> honour in a valiant fight to the end

Having recently witnessed my grandfather's slow decay into ultimately death from up close (living next door), I can say with conviction that there's no "honour" in "fighting to the end". He went from having developed trouble walking to laying stiffly in bed blankly staring ahead in just a month and one ER trip + hospital stay.
He then stayed in bed for just under two years only occasionally moaning or grunting quietly gradually losing the last bit of his muscle mass with the only exceptions being:

- getting sponge-bathed by a visiting nurse, my uncle or my father,

- getting put on the toilet chair to pee/take a dump if it didn't already wind up in his diapers while laying in the bed,

- getting wheelchaired over to the table in the next room to get fed some pureed mush that was (almost always) the same as the lunch/dinner my Grandmother was having,

- etc. one can get the idea

> Both also had huge support from loving family and friends, the way it should be.

Having the support from the family involved basically putting their lives on hold for ~2 years.
They always had to be there every single day to take care of one thing or another and watching my grandma take that for granted was frankly disgusting to witness.
I was roped into plenty of tasks as well but thankfully one of the things I could avoid was having to wipe my grandpa's ass or bathing him.
When my grandpa finally died in his sleep one night I wasn't really sad.
I was more relieved that he wouldn't have to suffer anymore - my mother and I sometimes wondered if even in his mental state (severe dementia, basically a drooling vegetable) his occasional refusal to open his mouth during feeding was the only little bit control he could exercise, even though he was then just force-fed instead by prying his mouth open enough to get the spoon in.
And the thing is, my grandfather was a VERY prideful man with strict principles during his conscious life. Going by what I remember from that time, he would've despised being in that position.

TL;DR: romanticizing long drawn-out physical and mental decay as some sort of "valiant fight" is just wrong and taking "huge support from family and friends" for granted during such death-spirals is frankly a disgusting attitude.
I don't think you quite understood what I was saying, reread the first sentence. You can be proud of coming from any culture, China included. I just can't fathom any reason other than racism for being proud of just your skin color.
Hold your hand to a flame and tell me there is no experience that goes beyond the material world. It feels like something to experience pain. Why? That is the question here. To deny that there is such an experience is self deceiving.
> This suggests that doctors would approve the killing of newborns even without a terminal illness.

Saying doctors would be OK with post-viability abortions in the case of a major (though still viable) birth defect does not at all "suggest" to me that they would be OK with the killing of newborns.

This is a super cool project and I will definitely be buying one. However, I've been burned too many times on Kickstarter hardware projects (most spectacular loss was the Lily Camera) - nowadays I just pay the premium for a guaranteed shipping date. Some companies like Glowforge actually handled multiple delivery delays quite well, and raised venture capital so they wouldn't have to touch Kickstarter funds for overhead costs.

Excited to follow your project and eventually have one sitting in my workshop!

How is a policy explicitly based on specific races not racist?

And who are "white people"? I really find the whole concept of "white people" racist. My Polish family were discriminated against for being Polish when they moved here, to the point of being shot at by more wealthy neighbors and consistent unfair treatment from the justice system. This was my grandfather and his brothers.

>Nope. Redlining, the entire history of USDA subsidies in the 20th century, the GI bill etc are far more economically impacting than any meager adjustments to the dominance of white people in business and government

edit: I've been flagged, I believe for what i was trying to say below, so let me try again.

This is something we as a society really need to come to a consensus on if we ever hope to end tribalistic hate. I really want to bridge the gap here, and I don't understand this. I believe in equality of opportunity, which is why I can't stand systemic racism or unconscious bias. I have seen no evidence that we can fight those particular things, not their down stream effects of equality of outcome mind, by actively treating people unequally within society. I am completely open to having my mind changed, but my understanding of history and anthropology leads me to believe that it only serves as a wedge.

Unless I'm misunderstanding the definitions here, that would seem to show that the third generation is identical (or better) in terms of risk of ruin?
