Some interesting data here.

- Mean age of 79.5 sheds light on Italy’s extremely high fatality rates; in essence, it’s the (very) elderly that are dying due to complications from viral pneumonia. Which begs the next question...

Why are they overwhelmingly treating patients with antibiotics in cases of viral pneumonia and not antivirals (Remdesivir)/ chloroquine?

Sure, these are “experimental” therapies but decent data out of China/South Korea shows these therapies work. Perhaps they found out too late?

- The younger fatalities (17) show multiple, serious co-morbidities and smoking is not listed; an assumption can be made a fair amount of these younger patients smoke. But again, an assumption.

- Almost 50% of patients showed 3 or more co-morbidities - this is high and important to note. 25% of patients showed 2 co-morbidities. Roughly 75% of patients had 2 or more co-morbidities (!).

- Sample size (2003) is good given their current 3,500 fatality numbers.

Not a medical doctor but a few things I’m struggling to figure out:

- How did so many elderly get infected? Did the disease simply spread in close quarters where many elderly live? Elderly folks aren’t necessarily out and about drinking espresso and touching surfaces yet alone having younger asymptomatic carriers cough on them.

I wonder if Italy is similar to a Kirkland, Washington situation. High density of elderly folks spreading infection.

It’s obvious that SARS-Cov-2 is highly, highly contagious but it’s interesting how we’re seeing these somewhat “bomb” explosions of infection: Wuhan > Daegu > Kirkland > Lombardy > NYC next.

Sure, quarantine works but the rate of new infection stays rather localized and then just annihilates everyone around it.

Perhaps it’s a viral load issue; viral load increases exponentially the more we have infected. Why you see doctors and nurses infected / critical and dying even with full PPE.

Let’s hope the Italians figure out a way to get this curve to fall of ASAP. Hoping they have a similar effect to Wuhan’s curve and just drop down rather than flatten.
Show HN: Orchestra – Model and data pipeline monitoring as a service
Hi HN-ers,

We're Teren and Qiyan, founders of Orchestra (https://orchestrahq.com). We help data scientists/data engineers discover, prioritize and investigate machine learning model performance issues in real-time. We're Datadog for machine learning.

We first came across this problem while Teren was leading a team of analysts and data scientists at a global bank. Their main role was to identify opportunities to apply AI/ML to drive business performance internally and externally. When he joined, several models were already in production but upon further investigation, there were a few that were unusable for years. One particular model need significant manual rework to make it usable again.

With an early detection system, model performance issues such as the one Teren faced can easily be fixed before it causes further damage not only to the business but the reputation of the data science community internally as a whole. That's the motivation behind Orchestra - to provide robust ML-specific tools to help AI/ML/data science teams build trust and credibility.

Our tools are designed for data scientists who are time starved with a million priorities. Let us handle the infrastructure and you can focus on improving the model to actually deliver value for the business.

We want to make it easy to use but also flexible enough to meet your monitoring needs for just about any kind of model you develop. In short, a few code snippets allow us to extract, monitor and analyze model inputs/outputs as well as the data pipeline.

We want to build a product that solves a problem and loved by customers so we're eager to learn from all the experiences you've had in this area and ideas on how you've built trust and credibility within your organizations. We welcome any feedback so please feel free to share. We're also looking for testers/collaborators to join us on the journey to building high quality machine learning models.

Thanks in advance

Look at this page for `capacity`: https://en.cppreference.com/w/cpp/string/basic_string/capaci...

False. Most games do target iGPUs, including most eSports and most indie games, which are the /most popular games.

The console AAA games are the ones that target proper GPUs because consoles have them. If they were targeting PC only, you wouldn't see them.

You said cores, not threads. In any case, 2 cores are still a thing. Even the new Macbook Air has 2 cores, so yeah...

Further, no one targets 16 GB RAM for a game. Not even the non-released, next-gen consoles have 16 GB dedicated CPU memory.

Similarly, not everyone one has an SSD and therefore companies cannot target that. Only in a few months with the new gen of consoles we will see actual games targeting SSD speeds.
Probably tens of thousands of undiagnosed, asymptomatic.

Aka super carriers.

The virus is smart and has evolved from an evolutionary standpoint. Infect younger and asymptomatic patients with the goal of spreading and infecting as many as possible. Eventually, the more infected, the more that will die. The young are just carrier pigeons and don’t even know it.
The timeline really depends on how fast it spreads but we need 40-60% of the population to have immunity to have herd immunity
> Elderly folks aren’t necessarily out and about drinking espresso and touching surfaces yet alone having younger asymptomatic carriers cough on them.

From what I understand about Italian culture, they kind of are. Older Italians seem to have much stronger social lives than in the US.

Thank you for the excellent write-up here. I'm sad to hear that Starsky is dissolving, but I have hope that the lessons learned here will be applicable elsewhere.

The point about safety being a low priority with investors makes sense but is unfortunate. I hoped that Google's investment in Waymo would push past this hurdle, but they're latest funding round makes it clear that they also have to deal with investor wants over the success of the technology. Really hoping to see someone get the funding to make this tech work reliably in the future and apply the same safety-first design that Starsky used.

> 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.

Also, your claim is incorrect as a general statement. The type structure of a given program is an abstraction of its value flow, but without that abstraction a compiler would not be able to optimize it nearly as well. A typed program will always be faster than an equivalent untyped program.

Creating an abstraction may also allow you to add a transparent memoization layer, which not only can make your program orders of magnitude faster, it can make previously unsolvable problems solvable (see how PEGs handle left recursion).

but at the same time, there's more anti-bacterial soap, better cleaning products and methods, improvements in material science for non-porous, easy to clean surfaces. so overall, it's possible we experience much less exposure, despite the lack of these metals in our immediate environment.

in any case, it isn't obvious that a (small?) increase in exposure would necessarily be bad for the immune system and people. there's evidence that reduced microbial exposures in children leads to an increase in allergies (e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1838109/)
This is encouraging for healthy youngsters BUT age and health are also the criteria for receiving treatment in Italy at the moment. As the epidemic grows the categories of people that get ventilation decrease and the deaths will get younger and healthier.

I'll be honest, I initially downvoted your comment as a kneejerk reaction, since I am so weary of seeing Hindutva activists claim that ancient India had nuclear weapons and airplanes. I’m sorry for that, because you are right indeed. The Bose in question is Jagadish Chandra Bose [0], and he seems to have been a remarkable man indeed. Everyone should know about him just like we recognize the names of Marconi, Tesla, and other scientists of his era.

There’s truth to this and perhaps I jumped to an invalid American based assumption, stupid given that I’m European.

In Europe, the elderly are out and about, walking, sitting at parks, drinking coffee, the works. They’re actually still doing this as we speak in countries, from what friends and family tell me. Go figure.

However, even if they are in cafes, grocery stores, parks - the numbers are still very high.

This virus is either incredibly efficient and contagious (spread by totally asymptotic carrier pigeon patients > elderly) and/or it’s been there for a long time. Months.

On antibiotics, aside from secondary infections, there’s a paper out talking about azithromycin:
“Our preliminary results also suggest a synergistic effect of the combination of hydroxychloroquine and azithromycin. Azithromycin has been shown to be active in vitro against Zika and Ebola viruses [20-22] and to prevent severe respiratory tract infections when administrated to patients suffering viral infection [23].”

Not sure of they used azithromycin but would’ve been good to see that verified.
HotBot was my go-to search engine before Google got popular, so thanks :)

The article seems to imply AOLserver ran pretty well (28,000 hits per second in the late 90s), and AOL used it with their users. How many hits were you getting that it didn't work? Or was it the nature of the workload (presumably db queries for search results) that were the bottleneck?
> Why are they overwhelmingly treating patients with antibiotics in cases of viral pneumonia and not antivirals (Remdesivir)/ chloroquine?

My guess is that they try to avoid an additional bacterial super infection with antibiotics. Also these antivirals can be dangerous to (very) old people. I think because of liver malfunctions. But take all I say with a grain of salt.. this is all stuff in the back off my head that I remember vaguely from my father (a doctor).

"China reports outbreak of deadly bird flu among chickens in Hunan province, close to coronavirus epicentre of Wuhan"
And that low chance of false positive can be easily derived (as in, just looking at the bars) from the Italian National Biotechnology Association graph, based on the known cases in Italy, which I've cited before. The numbers are orders of magnitude different, so the same can be concluded -- the can be no significant misrepresentation. There's the whole Italy and actual people dying or having to be connected to the machines to keep them alive -- a much bigger and more horrifying confirmation of low chance of false positives than just comparing thousand probes.

> I miss the optimism and feeling of limitless potential that existed around technology

Having grown up along with the Internet, I feel this is a common sentiment among those who experienced the early days when things were just getting started. It seems we're losing touch with the vision and culture that gave birth to this technology and made it seem magical, like participating in a collective evolution.

The commercialization of the Internet and the shared space it enables is a symptom of modern social priorities (as a sibling comment pointed out). It's part of the history of colonization of all public space and the public themselves. As one of the "natives", it's hard not to feel cynical about the transformation - but that, at least for me, ties in with a deeper cynicism about society and its values, the direction of culture and civilization.

On a more positive note, there's a kind of generational knowledge transfer, passing the torch: the history, the set of values, the original insights that formed the foundation are all (or much of it) still there, being taught/learned, carried on, elaborated and pursued further. As I get older, I feel more responsibility to play my part, to do what I can in my local sphere of influence. That also opens my eyes to what others are doing in terms of activism and education.
I wish there was something similar to the Haskell Haddock (https://www.haskell.org/haddock/) for Rust.

Something that would automatically generate the signatures and modules entry points/data types. These seem to be very neglected and generally hard to keep up-to-date in the Rust ecosystem.
Sorry for the ambiguous wording: more likely than before a period of strict isolation to be immune. There would still be a spike after isolation is lifted, but the total number of people infected by the end of this wave will be reduced.

Of course, the question is "how much" and whether that's worth the cost. But not overloading the ICUs is valuable on its own.
I wondered that, but they've made at least a couple of good product decisions in the post-jobs era. Most notably in my mind: the AirPods, and the iPad Pro (with pencil, and more powerful iOS).

I wonder if intubating these patients is actually killing them. I have ZERO evidence but is there an off chance they’re actually treating them incorrectly?

There’s the cytokine storm problem although I just wonder, for some weird and maybe even wrong reason, that the standard of care, the protocol for this particular viral infection is not intubation for most?

If you look at a video of the ICU or ward in Lombardy, everyone is either intimated or negative pressure oxygen. Yes, their Sp02 levels are bad and they have breathing difficulties. So I get why they are following standard protocol - but I just wonder if this particular infection, at its peak, requires a different approach.

But enough Doogie Howser from me.

Don't countries like ethopia skim the foreign currency sales of things like coffee in various ways (ie, low official exchange rate, then elites can resell at higher black market rate and give farmers the less valuable local currency).

This is a common issue in a lot of developing countries - and also makes investment harder because it can be very difficult to get your foreign currency profits out (elites only want to buy at fake low rate - if they had to sell at it they'd lose their profit).
On the contrary. Global is good, but it has to be globally distributed. Global cannot mean just make it in China.

Right now, since China is ahead of the curve, it is valuable to be globalized in many respects. But it is not enough.
> The virus is smart and has evolved from an evolutionary standpoint. Infect younger and asymptomatic patients with the goal of spreading and infecting as many as possible.

I think you are giving a bit too much agency to the virus. It has evolved in such a way that optimises for further spreading for sure, but I do not think it has a sneaky strategy to use young people as attack vectors.

What's more likely is that it has evolved to replicate and spread within the human population, while not acting so fast as to kill most people. The problem is that replicating at a rate that doesn't kill most people will kill some of the oldest and sickest within a population.
