Here's what we're using which I'm pretty happy with:

0. Self-hosted Gitlab and Gitlab CI.

1. Chef. I'd hardly mention it because it's use is so minimal but we have it setup for our base images for the nitpicky stuff like connecting to LDAP/AD.

2. Terraform for setting up base resources (network, storage, allocating infrastructure VMs for Grafana).

3. Kubernetes. We use a bare minimum of manually maintained configuration files; basically only for the long-lived services hosted in cluster plus the resources they need (ie: databases + persistent volumes), ACL configuration.

4. Spinnaker for managing deployments into Kubernetes. It really simplifies a lot of the day-to-day headaches; we have it poll our Gitlab container repository and deploy automatically when new containers are available. Works tremendously well and is super responsive.
Surprised no one has mentioned "Trading and Exchanges: Market Microstructure for Practitioners".

Lots of people recommending Ernie Chan - and he is very big in the space but he uses 100 words when 10 will do its a hard time slogging through it.

De Prado is incredibly technical , if there was a De Prado cliff notes Id say read that.

And don't forget if you are coding this stuff up, lots of people have but those books into re-usable code on github.
I don't get why coordination is equated by many people with centralization. You can agree on a set of measures that should be taken by everybody under certain circumstances and then let individual countries apply those measures.

There were three confirmation dialogs. Two of which we can blame the developers/company [1], one we can blame the EU’s good intentions but terrible execution idea.

Think this mostly boils down to the opinion that you should handle errors properly or ignore them instead of just logging them. This article might read better if you defined what "logging" means up front and make sure it's a well scoped definition. I can also think of a bunch of cases where logging is super important that aren't really covered by any of your arguments.

For example, if you have a micro services architecture in production in which many services might be accessed (or not) from a request of a particular origin, then you're going to want to "log" a unique identifier for that request and propagate it across all the systems so that you can tie them back to each other if needed.

Another example, you sell hardware to consumers. The hardware is composed of modules and components that all talk to each other (yep, it's a car), and how long those components and modules last is effected by environment variables (how you drive). You've got a couple of million of these things on the road. If you want to learn how to improve quality of your hardware, you need to "log" how your hardware performs in the environment that you don't control, so you can correlate failure with environment variables. Can't do that without "logging".
Are you all right?
What is WOO number? Otherwise- brilliant!
Thanks everyone for your replies. It does give me clarity and I feel that it wouldn't hurt me to buy 2 weeks supply of super essential things esp baby products.

I used to buy them like this before anyway, but something just felt wrong doing it today when supplies are running so low for everyone.
One of the things I would love to see would be a voxel-based fighting game. The rage at the time was for texture-mapped polygon fighting games, but the Jaguar was better at voxels (see phase zero https://www.youtube.com/watch?v=2OPcFdkj0GU).

TBH I reckon the Atari ST and Amiga could've handled a voxel fighter at a decent clip: https://www.youtube.com/watch?v=CmnZoUxXIQM at about 2:46
What externalities?
Several thoughts:

1. The point about them not actually making that much buying for $2 and selling for $20 is 100% valid. Amazon fees are $3, plus another $10 or so for shipping, plus labor, box, label, gas, etc.

2. On top of that, the business is risky, as evidenced by the fact that he's stuck with the products now. If you have a 50% chance of getting stuck with inventory, you need to make double the mark-up (actually more to account for purchase price) to cover that risk.

3. Obviously he was somewhat naive about talking to the NYT. The reporter clearly has a lot more experience spinning and extracting unfavorable quotes than he has with resisting hostile questioning. Disclaimer - I talked to the same reporter (https://news.ycombinator.com/item?id=22575940 I wrote about my own experience here), and I've also talked to and met both Matt and Chris at various conferences over the years.

4. If you look at the pricing charts, everything was basically normal until 1-2 weeks ago. There was a small increase which is reasonable with the increase in demand. At that point, there was nothing wrong with buying from stores or liquidators and reselling. The article says Matt bought this stuff up in February, which is before any states of emergency were announced, before demand blew up, etc. I think there's a distinction to be made between people going to stores and buying now, and people who did that a month ago.

Yah, maybe it's just me but the first thing I look for on any project is a bunch of screenshots. Doesn't matter if it's for a game or a statistical analysis tool.

A picture tells a thousand words and it can quickly let ppl ascertain whether the project is something we're interested in.

Of course, the next leap is actually having documentation.
You're comparing a country to medium sized cities though - on a continent with a population of 750 million people, versus a country like America with 350 million, it's like 350 thousand. What small City governments can do and how they govern is different from alrger cities like NY, different again from states and from the monster of the federal government or the European union

For that use, I would get some Techflex F6 split sleeving, or some of the velcro-closure stuff. Not only does it hold them together, it also provides quite a bit of protection from abrasion if you drag the resulting "snake" around the floor or whatever.

The problem with lacing an assembly that might flex, is that the cord keeps the cables from sliding against each other, and makes the assembly very stiff. So any flexing force is concentrated at points where it can overcome that stiffness, and this is bad for the cables long-term.

Inside equipment, lacing is used to keep wires from abrading against each other. In an office, it's used to secure them to frames for density, organization, and seismic reasons. In all cases, every piece of connected equipment is rigidly mounted, and no part of the laced form ever has to move relative to any other part.

That's just poor reasoning on multiple levels: it assumes supply, the argument that it prevents hoarding misses that as prices are driven up the incentive to hold increases, and it overlooks that some populations night need the good immediately so real harm is being done.

The gain is personal, the harm is social, this is ethics 101 and solipsistic pseudo-libertarion reasoning doesn't make it right.
One example is a pandemic.
The opposite is true in 2020: log everything. We now have incredible open source tooling for time series data, like ElasticSearch and InfluxDB. Disk space is almost free. There is very little downside to essentially tracking EVERYTHING!

Log everything but focus on logs and metrics that matter most to customers (eg reliability and percentile latencies).
A recurring symptom mentioned here is difficulty breathing. That's terrible and can easily cause harmful feedback loop. I'm mid-30s so I will try to defer medicinal interaction for as long as possible. To self-assess the seriousness of breathing issues I intend to make us of a pulsoxymeter.

Is there somebody here who could suggest a rule set for when to seek help?

Something like: seek help if SpO2

- between 85% and 90% for more than 48 hours

- between 80% and 85% for more than 24 hours

- below 80% immediately

(actually I do feel mildly ill and as if breathing is a little bit more uncomfortable than usual - but according to my pulsoxymeter SpO2 is at healthy 98% with a pulse around 60 bpm. so everything seems perfectly fine)
Not a single shred of evidence or a single claim that corona viruses mutate in a similar manner to influenza. You are indeed done. Perhaps you could spread the word? Not make the panic worse?

> Now try to come up with a solution for homelessness that works in both Spokane, Washington and Coral Gables, Florida

Isn't homelessness generally handled at the city and county levels? Both places can independently look at how different areas of the world have combated homelessness, and also share their successes (or failures) with each other without being forced to both do the same exact thing.

Iceland might very well be the richest country (Non city /oil state) in the world per capita. Measured both in monetary and non monetary terms. See: https://en.wikipedia.org/wiki/Economy_of_Iceland
You'll find a similar argument in any basic econ textbook. Put a cap on prices, then when demand rises for something (which normally leads to an increase in price, all other things being equal), the lack of an accompanying rise in price means there is no incentive to produce more of the good (no incentive for more producers to enter the market), so there isn't a corresponding increase in supply.

Might work okay in China, where the government can e.g. command factories to switch to producing masks, but it means American factory owners won't have any incentive to switch over to producing them.
Inappropriate metaphor
So low wage workers should abandon their jobs to spend their time procuring essentials at reasonable prices? Because right now there's a lot of speculation short-term, but things will go back to normal in a week or so after everyone has enough toilet paper to last until 2050.

Free market capitalism frequently generates outcomes that are at odds with a functioning society, and this is just another example.

> State is always the enemy in technology.

I work in data storage. Am I the enemy, then? ;)

> can't even imagine managing hundreds of servers whose state is unpredictable at any moment

Be careful not to conflate immutability with predictability. The state of these servers is predictable. All of the information necessary to reconstruct them is on a single continuous timeline in source control. But that doesn't mean they're immutable because the head of that timeline is moving very rapidly.

> can't be terminated and replaced with a fresh instance for fear of losing something.

No, there's (almost) no danger of losing any data because everything's erasure-coded at a level of redundancy that most people find surprising until they learn the reasons (e.g. large-scale electrical outages). But there's definitely a danger of losing availability. You can't just cold-restart a whole service that's running on thousands of hosts and being used continuously by even more thousands without a lot of screaming. Rolling changes are an absolute requirement. Some take minutes. Some take hours. Some take days. Many of these services have run continuously for years, barely resembling the code or config they had when they first started, and their users wouldn't have it any other way. It might be hard to imagine, but it's an every-day reality for my team.
> person-to-person spread of misinformation

You know, for as much as I've heard about the supposed danger of "misinformation", so many factual observations have been labeled "misinformation" early on, only to be later confirmed by WHO, a major national authority, or a medical journal.

The type of misinformation matters a lot, because if people take the concerns about permanent lung damage, reproductive damage, and the extreme contagiousness of the virus seriously, it doesn't matter if they were "misinformed" to some extent. If the misinformation encourages them to not take things seriously, or to breach social distancing (see Rudy Gobert, who should hope he hasn't committed homicide for a laugh), that's when it is the most dangerous.

It was acknowledged by the 2008 edition of the Guinness World Records as the largest computation in history.[22] With over 145,000 active computers in the system (1.4 million total) in 233 countries, as of 23 June 2013, SETI@home had the ability to compute over 668 teraFLOPS.[23] For comparison, the Tianhe-2 computer, which as of 23 June 2013 was the world's fastest supercomputer, was able to compute 33.86 petaFLOPS (approximately 50 times greater).”
> Obama was not caught unprepared during H1N1

Did the US actually do widespread testing for H1N1? Or do anything at all?

My memory of the H1N1 outbreaks are that it was downplayed heavily in the media, and doing nothing was our response. It's pretty easy to do nothing. The way I remember it is that Asia did all of the heavy lifting by quarantining anyone with a fever.

How often does anyone get charged for this other than a few token made to be an example for the most egregious behavior? Price gouging laws seems to be mostly a threat rather than an actual attempt at regulating pricing. It's similar to how the police will arrest huge numbers of people during a protest and then drop the charges against almost all of them the next day. The backbone of the protest had been broken so it no longer mattered if they swept up a bunch of bystanders with protestors and rioters as they're all let go. I wonder how well any of these gouging laws would stand up in court if the state didn't quickly drop charges when challenged.

Disclaimer - I probably did work somewhat far from protein folding research, but still could be considered a "potential consumer" for such research since projects in my lab for example tried to make a therapeutic protein better by structural modification based on structures published by others.

I will say that there's nothing wrong with continuing the folding research that's being done. We have a ways to go before purely predicted protein structures (as opposed to structures from crystallography or EM) become trustworthy enough to make research decisions based off of. But we can't get there if we don't continue the basic research! In that sense I'm all for these studies. A lab I always appreciate (purely from perceived merit of the papers I see continuously from) is that of David Baker. They seem to make meaningful strides towards making synthetic protein folding more powerful as a tool among other projects.

However what I see as problems are two things in this field:

1. Definitely have seen papers where they'll try to do some molecular Dynamics simulations on some protein related to a disease but it's not clear if it's meaningful to anyone - people actually working on the disease therapy probably weren't even asking for these insights if there were even any; these low-hanging-fruit studies also don't aid the progress of folding and Dynamics research either, because they were just applying standard techniques to a problem domain. Often times these are just cash grabs by researchers who have specialized in the mol.dyn fields and end up writing grants to disease research agencies allegedly in aid of curing the disease but practically not. I know this because my lab did this blatantly. When anthrax was a real threat we got funds for anthrax related research, then we shifted to MS, now cancer. I wouldn't be surprised if they suddenly write grants for corona virus related research! This goes on in all these fields.

2. I argue that folding@home keep advertising misleadingly that they're gonna help cure aids or corona or whatever. I don't think they are, not directly. In a very vague way this feels more like war profiteering to me - these experts are exploiting the current fears to canvas their projects (even design them around this) and giving what is closer to false hope than anything that people are contributing towards end goals of curing disease. I feel like they should be honest about it - this is more basic research than anything else, so they should just say they want computational power for basic science. If people still choose to give their resources, great. Otherwise at least you live and die with dignity.

Anyways this is of course a rant from a PhD who got sick of the system and left, and someone with only an associative knowledge of this particular field. Hence these thoughts should be taken with a grain of salt!

The point is that capping the price of e.g. masks means _fewer masks_ are produced, which is worse for stopping the pandemic.

Alive is just a word. It means different things to different people and any formal definition will necessarily be arbitrary.
From an economics stand point, I don't understand why the government should ban price-gouging. Doesn't this place an artificial price ceiling that will ensure a shortage of goods? I would personally rather stores have items such as food/water at marked-up prices than not at all.
I believe your comment is in good faith, but I also believe you are wrong.

This approach sounds very similar to the UK approach, overseen by Whitty[0] and Vallance[1], and agreed with by Neal[2] and Ferguson[3] (and I assume more but I haven't looked very hard). I don't think all these guys are morons. Well, I hope they're not.

Haven't got a link but I heard him speak on UK Radio 4's Today programme this morning.
High prices induce production that would not have occurred otherwise. They also curve demand downwards so that only those who really want the item will get it. There is little reason to outlaw price gouging save for humans have a disgust response to people who profit from tragic events. Absent these laws, there would be incentive to create stockpiles of needed items before a disaster and retool less-efficient factories to produce now more-profitable items during a crisis.
We do not think markets are magic. We think they are machines that run on price signals, and bashing these signals with hammers will degrade the efficiency of the machine.
Do you actually think our economy needs 200x as much hand sanitizer production?

If the demand runs high enough for long enough, it wont be an emergency, and emergency measures don't apply.
I would rather the price 10x if it means people can buy toilet paper, than have it be unavailable to all. But I am thinking rationally rather than emotionally.
> In some other fields humans are modelled as fluids or herds, devoid of individual judgement/decision making

From a game theory perspective, following the herd in this case could be the rational choice on an individual level even if you have decision making. If enough people think there's a shortage coming, and they stock up in preparation for it, then you get an actual shortage as a result. In this scenario, there's very little potential downside to stocking up (at least for non-perishables) from your perspective, since even if you're wrong then you're just saving a few trips to the supermarket in the near future, and you might even get a discount if you buy in bulk (incl. saving gas, time, etc). But there is a potential downside to not stocking up, since you then risk not being able to later find the item when need it again, or having to pay more for it if you do find it. Going further, if you think that other people are going to start panic buying, then it makes sense for you to do so as well. But by doing so you also contribute to causing the shortage, leading to a self fulfilling prophesy.

So I don't think it's necessarily that people aren't being logical, but more that they're acting based on limited information.
I read that here in the Netherlands the testing capacity is limited by a shortage of little plastic slabs that hold ~90 test samples at a time. One tactic to increase capacity is to not test the samples until the slab is full, which also delays test results.
