How to Make Remote Work Effective for Data Science Teams
The Circllhist algorithm is interesting, but I get an uneasy feeling from the use of a _relative error_ measure to evaluate the performance of quantile estimation. Note that other authors don't use this measure.

Dunning uses Mean Absolute Error in his latest T-digest paper: https://arxiv.org/pdf/1902.04023.pdf

Cohen uses Normalized Root-Mean-Squared Error to evaluate sampling schemes, which are equally capable of estimating latency quantiles: https://dl.acm.org/doi/abs/10.1145/3234338

The problem with Relative Error as a measure of accuracy is that it depends on the location of the distribution. The same size absolute error becomes a large relative error near zero and becomes a small relative error farther up the number line.

Another thing about this study is that only one value for the T-digest quality is tested. Of course, the T-digest quality parameter equates directly with compressed size, so it's unsurprising that T-digest's size is fixed throughout the experiment. I also suspect that the choice of data set matters quite a lot in this study. If your latency values were clustered around a small range, then the algorithms like DDSketch and Circllhist will indeed have relative error less than 5% (as they prove) but T-digest will be significantly more accurate.

Crisis fatigue. The boy who cried wolf syndrome. I think it plays a part, I would love to know for sure. Such things are often impossible to know, but it's not impossible to realize that there are things that are unknown.

personally I was more thinking something like xymox or sisters, without the haunting vocals of either (it actually reminded me most of a local band from the late 80's and early 90's, but definitely not them). but I guess we hear what we want from it :)

The SAT is designed to be an intelligence test, not a course final, and it's possible that the large team of education and psychometrics people who've been working on it for decades know what they're doing.

Armchair speculation: there are probably some really bright kids out there with poor test-taking skills, and prep likely has a dramatic effect on scores for them, but most students are not that.

Did you actually sit an SAT before you started gaming? What was your improvement?

I want to go out today because its going to be 75 out, but I'm afraid that a lot of people will head out too. Its a tough situation.

Not everyone has perfectly reliable access to the internet.
The SAT is not fair. By taking an expensive prep course, you can potentially increase your SAT score by 100 (although that's quite extreme, the average improvement attributed to SAT prep is closer to 20 points). That's a significant, but not earth-shattering improvement: it moves you from the 75th percentile to the 84th, or from the 97th percentile to the 99th.

Now let's compare that to other criteria used in the college admissions process.

It's way easier to have impressive and relevant extracurricular activities if you're rich and go to a good school. And unlike SAT prep, acquiring good extracurriculars will definitely take years of your time and money.

Well-written admissions essay? MIT requires one. But you do it at home, instead of a tightly controlled testing center. So if you're rich enough, you can have ghost-written admissions essays. Needless to say, this process can turn even a completely worthless essay into an impressive one.

Creative portfolio? Unless you're in the 99th percentile of musical talent, the difference between "I write songs that I play on an old guitar" and "an orchestra performed my composition" is money. The former is probably not even 75th percentile; the latter, probably 95+.

Alumni parents who would be likely to donate big bucks? You don't need an expensive prep course to get that, yet it can provide your application with a much bigger boost than 100 SAT points. And unlike the SAT, if you don't have alumni parents to begin with, then you'll never get this boost, no matter how much extra work you put in.

The SAT is not fair. But it's the fairest admissions criterion used by U.S. universities today.

I think everyone would like to see the CDC be better funded. Hindsight makes that an obvious mistake, but monitoring C19 should have been their number one priority in any case. From January onwards it was clear that it was the number one threat. There's still no explanation (afaik) for why they rolled their own test instead of using the WHO's test, nor have they effectively communicated their plans for ramping up testing or medical capacity. I don't see how this is anything besides mismanagement (e.g., how does funding impact which test they used? Presumably being under-funded would prompt them to use the test that the rest of the world is going with instead of rolling their own), and I really hope congress or the justice dept rips into this after the crisis is averted.

EDIT: Note that I say all of this as someone who is a big believer in "it's almost always more complicated/nuanced than it looks", but there seems to be no information about said nuance or complexity.
> > All abstractions leak. I cannot make an abstraction perform better than what's underneath

> Performance is not within the scope of abstraction. This is a category error.

It's not within the scope of abstraction... until it is. When that beautiful abstraction does exactly what you need, but does it too slowly to be usable in your circumstances, performance is not separable from the abstraction. (I mean, yes, performance is part of the implementation of the abstraction, not the abstraction itself. But the moment I have to care about the implementation of an abstraction rather than the abstraction itself, the abstraction has leaked. Performance is absolutely one of the ways that this can happen.)

And, as a concrete example, the STL went to great lengths to specify the performance of their abstractions.

I think browser product teams are out of step with what users want these days. It is easy to confuse the browser ecosystem with users. Or even claim that the browser ecosystem is good for users, and therefore doing things to improve the ecosystem _is_ doing things the user wants. In truth, the user just wants to see the web page and have the browser get out of the way. You know who does that well? Native. Identity and payments are now _solved_ there. The web is still trying to figure out this out and probably never will. Too busy working on things that don't matter. Then something like AMP shows up, which actually builds _on_ the ecosystem, in _favor_ of the user experience, and people blow up about it. The browser ecosystem is sort of in a sad state, leadership wise.

I would agree with that suggestion more. As in it sounds derivative of those, not that it could be one of those bands. It definitely suggests "local band" to me.

Although, what I was thinking of might be the guitar riff at 10-12 seconds in, not totally unlike this from 1982

Again, in the sense of it might be derivative of that. Any kid who had a radio in 1982 would have heard it.

Bingo. On Feb 18, China released the 6th edition of its treatment guidelines that included a Chloroquine recommendation. They've subsequently updated that guidance to reduce the dose

On Feb 19, Chinese authorities published this paper: https://www.ncbi.nlm.nih.gov/pubmed/32074550 which provides basically no details except that Chloroquine works.

Everyone who was paying attention saw this. The U.S. gov should have started ramping up production at that time, but four days later Trump tweeted "The Coronavirus is very much under control in the USA... Stock market starting to look very good to me!"
> Comparing GraphQL to REST is apples to oranges

Just because you say that, doesn't make it true.

> most of those endpoints load more data than they need

GraphQL proponents seem to forget query parameters exist. It has never been the case that REST has to return more than you need. Never. Not now, not ten years ago. Why people keep repeating this obviously false claim is bizarre.

The hoops you have to jump through to get GraphQL efficient as off-the-shelf REST are rather insane. Caching, both client and server side, have to be entirely reinvented. What Apollo does may be open source but it's also proprietary. And at this point, a single corporation controls the entire stack. Without Apollo, GraphQL is a terrible joke.

Anybody cheering the exclusion of some test or other, because it was a pain to study for in high school, is simply not noticing the frog-boiling secondary effects going on. Every bit of emphasis taken out of objective results mean more advantage for smooth talking, photogenic, well-connected people.

Yes, some misguided parents waste thousands of dollars on SAT courses. But students can also prep using the $20 official book, which is what I did, and what I still regard as the best option. Even if money helps incrementally for tests, it helps for everything else even more. International volunteer work? An inspiring (i.e. college counselor approved) essay? Recommendation letters from authoritative people? Anything that requires equipment, like computer labs or robotics? It all costs money -- and in many cases literally measures nothing besides how much money you have.

I am not sure if this is some kinda RDP attack & that's why I'm here.

> There's still no explanation (afaik) for why they rolled their own test instead of using the WHO's test

The explanation is obvious, isn't it? "We thought our test would work, and it would be better."

It was stupid, to be sure. It would have been a stupid risk even if it had paid off—although in that case, few would be chastising them, and many would be thankful.
> And then what?

They touch their mouth, or eyes, or nose.

> How does the virus get from their face into the lungs in enough quantity to infect them?

They're already infected. I don't understand the question. Are you asking how the virus replicates? It's a strand of RNA that takes over human cell replication. It binds to ACE2, which is how it targets lungs. https://blogs.plos.org/dnascience/2020/02/20/covid-19-vaccin...

People touch their face all day everyday, even when they've been told not to. Even when they're telling other people to stop doing it. https://twitter.com/Kojoanan/status/1235275598697771011

It's unusual for people in public places to be coughed on. I can't think of it happening to me in the past 5 years.

Healthcare professionals wear masks (and goggles, and protective clothing, and sometimes gloves) because their work involves close contact with ill people who are coughing over them.
This is a great reminder, thank you for pointing it out. Interestingly during the 1918 Spanish flu aspirin was a new drug and was given to people in an effort to reduce fever. The problem is they gave it in doses that we now know is toxic. There is some evidence that patients treated in hospitals with aspirin had a 30x!!! deathrate vs those treated "homeopathically". This YouTube video goes into the history and context of it ...

I beleive in modern medicine and science but we should be careful about being overly optimistic and harming people by giving them a powerful drug that hasn't been tested properly.

Seeing `for i in range(len(lst)): lst[i]...` gives me hives. That's cool if you're wanting to be super explicit about how the indexing works, but in this page it goes on to say "or you can just write sum(lst)" without worrying about the indexing.

I would write the explanations like:

result = 1
x = [1, 2, 3, 4, 5]
for number in x:
result = result * number
print(result)

which in my opinion is much closer to the way a mathematician would think about the process.
Not only that, but these prep courses tend to assign practice SATs that are harder in the beginning and easier at the end, to give the impression of rapid progress.
That's right. What we have today is more of a bus but for customer event data.

Let's say you have a website or mobile app and you want to collect all the user interaction events (clicks, searches, impressions) in a data-warehouse like Snowflake.

RudderStack can do it for you. We have SDKs (Android, iOS, JS, Python etc) which you can use to send events. We have a corresponding backend (you can run it or we can host it) which will collect these events and dump into your warehouse.

You often want to send (subset of these) events to other 3rd party websites too like Amplitude for analytics, Braze for marketing automation and so on. RudderStack can forward events to those too so you don't have to embed multiple 3rd party SDKs and understand their library etc.

The second part of this is to create a unified view of the customer as you mentioned and take action on that (e.g. find all churning users and send them email). That's where Segment has a product called Personas and we are working on something similar but it's not launched yet.

Though even before, you can build that customer view on top of your event data in your data warehouse by using SQL or a tool like Looker. For example, you find all churning users by writing a simple SQL query. And then send that result by something like Looker Action Hub.

Happy to discuss more here or offline (email: soumyadeb@rudderstack.com)
As someone who has used similar accommodations (though not specifically on the SAT), yes. Dyslexia will hold you back in college. SAT is intended to measure odds of success in college.
You are puting it mild. Those people are often on bunch of drugs concurently: ACE inhibitors, NSAIDs, anti-inflamatories. Many of those drugs deplete essential nutrients such as Zinc, vitamin C etc. Maybe that is the dominannt reason why older folks have such incidence. I wonder what are the stats for old & healthy (rare thing indeed, but not unheard of).
Black swan events extreme enough to push our normal operating infrastructure to the limit are very hard to prepare for efficiently and effectively. Preparing for them to double up is likely a fool's errand. This is obviously cold comfort if we have an extinction level event on the heels of a pandemic, but at some point you have to just accept your fate.
Also - different reporting strategies. Germany is not always reporting someone as a CV death if the dominating factor was something else, whereas Italy reports them all as CV deaths. Or at least that's a widespread theory I've seen. It's hard to imagine such a huge difference can be down purely to testing.

I think the next days will see people dig into these stats and start a more complex discussion about what exactly it means to die of this virus, what exactly capacity means in a world where doctors can go to enormous lengths to save every life in quiet times but can't in crisis times. Just comparing raw numbers doesn't tell us the whole story.
What if it turns?

Form 4868 requires you to (on line 4) give an estimate of the taxes you will owe. The form's instructions say, "Make your estimate as accurate as you can with the information you have. If we later find that the estimate wasn’t reasonable, the extension will be null and void."

Because of the difficult situations many people face right now, it's helpful to have one less thing to worry about. Some people are sick, unemployed/furloughed, trying to save their business, healthcare workers working 80 hour weeks, away from home and unable to travel back, unable to meet with accountant, etc.
