Most smartphones lenses are f1.8 to f2.5 which is plenty fast.
The images aren't sharp because the sensor is too damn small, it's more about sensor size than pixel density. That's why a 4x5" sheet of film still blow any digital camera away in term of details, sharpness, tonal range, &c. even when using 80 years old glass in front of it. You realistically can't get more than maybe 12 mega pixels of data from a phone sensor, you can't cheat optic laws by adding pixels.

This is the new 108mpx sensor used on phone, zoom anywhere in the pic and it looks more like a blurry abstract painting than a picture:

Only through meaningful antibody mass tests can we decide the true scope of the spread, thus the real numbers of fatality rate.

This is pretty cool. I didn't really get to do this sorta thing with a speech therapist until I was in middle school. I think it'd be pretty good for young children.

One small worry... I wouldn't want the child to get overdependent on the device. Perhaps it would be good if they only wear it for a certain portion of the day? Not sure.
Germany had colonies. East European countries are not rich. East India Company was the most profitable corporation in the history of humanity. It accumulated the wealth much greater than any of the current corporations. And contemporary corporations wealth is mostly ones and zeroes increased arbitrarily with ever increasing speed.
By the way, here’s an anecdote for the flip side: at one of my internships I was working on a tool to process large log files, and by careful application of Aho-Corasick I was able to make it about 50 times faster on the dataset we were dealing with, which made using the tool change from “let’s go grab lunch while this finishes” to “let’s stream the logs through this live”. Sometimes you do know how to make things faster: just make sure to test them before you do, and asking why something is a certain way is always a good thing to do before proclaiming it’s broken.
Same. One manager of mine gave me a special project to work on which turned out to be busy work while they waited for HR to complete the lay-off paperwork. The meeting to share my results was remote, and had him and an HR person it it. Fuck that guy.
Ask HN: Covid-19 online contact tracing?
With the abundance of data from social networks, I would thing it would be feasible to implement a sort of a crowd-sourced contact-tracing website. Something along the lines of...

1). User indicates they have the coronavirus
2). Site fetches potential locations they may have visited, and people they may have interacted with based on their social media data.
3). User indicates interaction with said locations and users.
4). Risk profile for other users is updated.
Before administering a vaccine into everybody, we must first make sure it's not worse than the disease (on average, what is a very high var).

This test takes some time, so no, not on the next 6 months. One can realistically expect it by 2022, if we are willing to rush and accept some risk.

By the way, 6 months is how long it takes to create a batch of flu vaccines.
Yup, linear data reads are easily 10-30x faster than random thanks to cache miss penalty staying static since the 90s.

If you want to see real-world DDR speeds figure out what algorithms do linear reads.

Apologies; my thinking was:

* counter the emerging anti-Asian sentiment

Agree that my last statement could have been more productive.
It's not even that. You could have a normal hash table with a decent hashing function, and you'll still get beaten by a flat array for small n (hundreds, low thousands), because the array is contiguous in memory - so operations like search or moving stuff around after addition make extremely good use of CPU's cache.
Why would 1) be an issue at all of the service was a public utility or not? It's not like a website will not use HTTPS just because it's on publicUtil.

2) is problem regardless. Something to be addressed, but it's not anything new just because it's becomes a utility.

I could see where 3) & 4) might be questionable. If it's gov't funded, then they like to tack on a lot of rules about what can/can't be used on the service. Obvious things like porn/p2p/etc would be blocked, but would access to things like Planned Parenthood be blocked too?
As a senior dev, I wish that I could say I always knew more than my interns, and that all the code that's there is because it was carefully planned to be that way.

But more often than not, I don't, and it's not.

My take on it is that for the most part senior devs are a lot more paranoid on breaking things and don't want to make code changes unless enough people are asking for it and it'll make a notable difference. Even making things strictly faster can break users if they depend on the algorithm being slow (an extreme edge case that you'd usually say is the user's fault anyway, but could nonetheless be relevant in things like optimizing away a spin-wait).
The possible end result of the disease is death. Which cure is worse? A 44 year old school teacher and father of six died in my county. He went from sick to dead in a week. He had no underlying conditions that made him "at risk." By all accounts, he was active and healthy. The population of people who are at risk of death or long term lung damage are those that can be classified as "human."

I don't particularly care if people don't want to protect themselves but this isn't about selfish individuals. This is about everyone else. If, like some politicians, you are willing to "sacrifice" yourself, please do it quickly and away from populations.
-27°C happens there once in about 10 years, and the coldest winter in a century was in 1941-42 (because of General Moroz on duty!).

This year Moscow basically didn't have a winter, in my town near Urals it was pretty similar with 2002.

Since I looked around a lot for newer numbers, I thought I'd point out some newer numbers in my reply to the sibling comment [0].

In summary:
Data for the US from 2016-2018 suggest 93,000 ICU beds total, that is a ratio of 28.43 per 100,000. (research referenced in WoPo article linked in the comment below).

For comparison, Germany (official 2017 data) has 28031 ICU beds total, a ration of 33.76 per 100,000.

Both countries likely have the highest ratio in the world at this time.

Hi David,
Thanks for doing that. As someone that was affected by the layoffs, this is really helpful.

Currently on the final round with Facebook, they mentioned that they hire L5 and above. E3 & E4 is on hold.
No, in an in-person layoff situation. I was addressing the comment I replied to where it said "This is equally true for in-person layoffs".

I've been in an office during an in-person layoff situation (surprisingly only once during my 15+ year career), and they were definitely taking advantage of it being done in person.
I would guess that there are translation agencies in China that specifically hire native English speakers. Maybe ask around in online expat communities?
One big factor is the lockdown in many places.

Working from home when I can go to the gym at lunch, the doctors office at 9, pick up X and Y hour, etc, is a lot different than what we're dealing with now - which is: "you're WFH but can't do anything else."
Plastics are very easy if you have in house tooling capability. In 2002 I was working in a plastic moulding part of the factory that produces commutators. We went from 0 to fully developed product in 24 hours and were ready to mass produce. Hundred parts on three machines per minute. And this was 2002. I imagine today it's even easier. So, indeed this is not a hard problem because it was solved decades ago.

I am going crazy, but my kids are also learning an absolute ton from having all this 1:1 attention from someone who is totally invested in them. I've seen big strides from each of them. Their character is really coming out.

I'm one to look for silver linings; this is surprisingly one of them.
Hopefully we'll discover the tradeoff is less severe than that, but if not it's going to have to be. I don't think you realize just how unhappy people are with being locked down; it's very likely we would see violent rebellions against an attempt to impose a second one.

Ask HN: Books giving practical advice on starting a solo SaaS business?
My goal in life (as of right now at least) is to start my own SaaS business so that I can eventually quit my 40 hour work week and have more time for things I enjoy doing. To reach that goal I am first compiling practical advice from people who have already been through that process and are now sharing that advice around ideation and idea validation, marketing, pricing, etc.

I've been looking for book recommendations on this topic both here on HN and also on Indiehackers and while there are many books that are most certainly relevant in some ways and generally just good reads, I would like to start out by asking you if there are any books you've read that specifically give this type of advice. I say books to keep it simple but am of course also open to other types of high-quality resources like blog series or conference talks.

Looking forward to hearing about all the great things you guys have read!
If you’re interested in spatial interfaces it’s worth looking at John Underkoffler’s work (Minority Report and Oblong Industries).

Totally agree, as someone that's jumped back and forth between software engineering & data science. Data science programming already brings out my worst habits - mixing business logic everywhere, using libraries with odd APIs (pandas, matplotlib) => trawling Stackoverflow for code snippets without really understanding them, ugly performance optimizations.

Add poor version control practices and the dawning realization that you don't know whether your code ever worked or just seemed to work because some variable was in scope that shouldn't have been, and it quickly becomes chaos.
Not to ignore the forced nationalizations, thinking that having one "state champion" would allow competitiveness against IBM. Of course innovation went to hell given the aggressive minimization of internal (UK market) competition.
Arkouda [1], [2] is a recent and substantial example use of Chapel. It's a Python package that supports a subset of NumPy operations on distributed Terabyte-scale arrays implemented using a server written in Chapel. It currently involves ~10k lines of Chapel code.

Other recent notable examples include using Chapel for Dark Matter simulations [3], tree-based search algorithms [4], and CFD simulations (to appear at CHIUW 2020 [5]).

Your point is taken that the Chapel webpage could be better at pointing to such examples via a "powered by Chapel" section or the like.

Worse than killing millions? What's the economic impact of that?
There is, it's just done subtly.
I do not think mixing up the practice of science with how ideas and policys are being spread is productive. We are beings who care a lot about what other people do and about our own turf, that will have a greater effect on science even if we get perfect reproducible results.

Over all I think we make progress, even if it's needs to be backwards at times.
that's somewhat disingenuous, taking away agency and ascribing it to other nations - some of which haven't done so great in their own coronavirus efforts. so that doesn't really make sense to me, at least not in the 21st century.

in my experience, Germany is quite conservative (lagging behind in smoking bans, preferring cash over cards until the coronavirus hit), but wants to do the right thing (look at e.g. solar power subventions). them being a federal republic means they have similar jurisdictional issues as the US, but less hamstrung by a crippling fear and distrust in the federal government. those traits, if i'm accurate, would also explain it.

(what is still there as a disparity between some western states and eastern states.)
I live in NYC. It is entirely reasonable for those of us fleeing here to rigorously quarantine for two-three weeks (I am still here). It is entirely reasonable for law enforcement to get involved with making sure this happens. If there are any moves to actually seal off NY then its a declaration of Civil War.
I think it's hilarious that you are deeply concerned about the shocking immorality of setting a fair price. But have absolutely no moral problem with large-scale worker exploitation.

For those not quite so consumed by their ideology, let me point out that a market economy can only work when relevant factors are included in the price.

E.g., if we want clean rivers and oceans, we could make everybody who ever makes a purchase study the manufacturing process and supply chain and let them decide as individuals to trade off global pollution against sticker price. But even if companies were incredibly transparent about this, it wouldn't work. We'd all be paralyzed with information and analysis overload every time we tried to buy so much as a pack of gum.

So instead what we do is use regulation to force people to price in the no-brainers, and then try to enforce clear labeling at the margins. E.g., there are legitimate disputes about the environmental impact of farming, so you can pay extra get produce that aims to be lower-impact under the regular "organic" label. Or one way we could solve our global CO2 problem is just to put a price on CO2 emissions and then let pricing adjustments flow through the supply chain.

Here, we already have long societal agreement on what reasonable labor standards are. E.g., the 40-hour work week and the 8-hour day go back more than 100 years. We have worked hard to reduce labor exploitation, and for good reason. So rather than absurdly insisting that each person try to calculate a non-exploitative wage adjustment every time they want a pizza delivered, I think we should just require fair wages and then let companies price that in.
I think that has a lot to do with your municipality. I have municipal electricity and not only is it very affordable, it's 100% renewable because they started the shift to renewables back in the 1980s. They haven't had to raise rates in years. My internet is also municipally owned and it is about half the cost for double the speed as Comcast, which is it's only local competition. So, I think it largely depends on how well the government is run. If government officials look out for the public interest, listen to science, and think long-term, we'll get better outcomes.
That's a great example; the most important part of your anecdote is the end which says what was the user impact? There is no prior reason to believe that a 50x speedup is actually a win; taking an algorithm from 100K nanoseconds to 2K nanoseconds when hitting the file system takes billions of nanoseconds is not a win for the user, and taking an algorithm that takes 5000 years down to 100 years is probably not either.

But a 50x win that, as you note, goes from "let's have lunch" to "let's change this one thing ten times and re-do the analysis to see which gets us the best results" is a huge game changer; it's not just that it saves time, it's that it makes possible new ways to work with data.
> the array is contiguous in memory - so operations like search or moving stuff around after addition make extremely good use of CPU's cache

Also - if I see someone try to use a linked list for an enormous data structure again.... Wow it does not scale worth crap because it turns out that the hardware is actually important, and contiguous memory is amazing.
Ask HN: Automate Bag Valve Masks
The manual alternative to ventilators is bag valve masks[1]. NY is considering training their https://en.m.wikipedia.org/wiki/Bag_valve_mask

HN is full of tinkerers that could probably come of with endless cheap, efficient and effective methods to automate bag valve masks so they could be operated hands free under supervision.

Just a thought for people looking to help and/or for the latest startup idea.

That is just a single example. You go out with your car, you get a coffee in a crowded Starbucks, go to work and test positive. Now what? There's a new cluster.
This is still being done in the U.S. by "chiropractors" pushing their own mixtures of zinc lozenges and herbs. Google "chiropractor" and "COVID-19" if you want to be disgusted. And local news channels are reporting on this as if it's real.
I've worked with juniors who always scope creep their very simple introductory tasks. Something as simple as "add these two fields to the existing API response" suddenly turns into "change the method signature of 90% of existing methods because DTOs make code lines shorter".
For the experiment to be fair we should spend three months unable to leave our offices, and have everyone bring their kids, and be responsible for janitorial, barista, and cafe services.
I'm not sure I agree with your premise on tests primarily helping on the down slope. However, even if that's the case, we don't have to choose between masks, ventilators, and tests. All 3 can be pursued at the same time without harming other efforts. The manufacture & supply logistics of these items don't really overlap. No one is going to stop making & shipping masks or ventilators because of this.
I am thinking I might fuck around with it soon for some standalone art, but I am currently in the middle of a multi-year comics project[1] that pushes Illustrator really hard to produce complex, painterly work at high speed and really don’t feel like changing horses in the middle of a stream would be a good idea. :)

In my parents county, there is one village with 9 cases out of 800 inhabitants that has been put on full lock-down, nobody is allowed to leave the village.

In that case I don't think your previous comment makes much sense.

but it's not uncommon for jr. devs to believe every piece of code deserves the most efficient runtime. Runtime speed causing projects to fail is very uncommon. What does add an incredible amount of work time is combing through a codebase looking for micro optimizations. I've never once seen a jr. dev who claimed to care about efficiency start by writing benchmarks over large parts of the system and using that to find real bottlenecks. No, they always comb through the code trying to impress the sr. dev. with their algorithmic knowledge.
