That's not true. You don't need expression trees (or equivalent), you can walk and interpret the specification directly. Expression trees are just a trick to compile this as code. But you can do that in any language that can compile code at runtime (of which there are, unfortunately, few).

From Common Lisp's perspective, the example given is just:

`(and (> divident 0.025)
(< payout-ratio 0.5)
(or (< pe-ratio 20)
(< price 130)))

You can walk that tree recursively as-is, calling appropriate operators and substituting correct values.

Or, you can wrap it in a (lambda (divident payout-ratio pe-ratio price) ...) and pass to (compile ...), and get a piece of executable code. With perhaps a line or two of book-keeping (that can be added by your code, and not necessarily typed in by the user), you can make the rule declare which variables it cares about. So a full example:

(let* ((rule '(lambda (data)
(destructuring-bind (&key divident payout-ratio pe-ratio price &allow-other-keys) data
(and (> divident 0.025)
(< payout-ratio 0.5)
(or (< pe-ratio 20)
(< price 130))))))
(executable-rule (compile nil rule)))
(list (funcall executable-rule '(:divident 0.5 :payout-ratio 0.4 :pe-ratio 50 :price 10 :other-data 42))
(funcall executable-rule '(:divident 0.5 :payout-ratio 0.5 :pe-ratio 50 :price 10 :other-data 42))))

How to Connect a React App to the Blockchain
This is a really good question, and the simple answer is that Slack uses an unmodified version of Electron, and it’s not a good idea to make custom modifications to that project for such a small, niche feature. The cost/benefit just doesn’t make sense for Slack, neither to me, nor to Slack management. But Electron didn’t even exist when Screenhero was acquired, and so the constraints we eventually faced were not possible to predict when we got acquired.

Is working from home a possibility for the tens of millions of developers and call center workers?

How's India's internet access at homes? I lived in S. India about a decade ago, and the internet was okay at the various IT offices, but it seemed a lot of office workers used their work PCs for a lot of personal business like banking and media (i.e. after hours), and I assumed this was because access was poor in home residences.

But maybe it has improved in the last decade.
Distance is not something Indians are used to, we measure distance between vehicles, while driving!, in centimeters and not meters.

Jokes aside, this was a needed measure in India. I just hope the government gives a helping hand to the poor, even if it means I have to pay double the tax this year.
Hey jsherwani! I just tried it out and it works amazingly well. Nice job.

Can you go into some detail on the tech stack you used to make this?

A virus also lacks the ability to even duplicate its own genetic material without the help of a host cell. The set of features a virus lacks is much larger.

On the other hand, all animals depend on another form of life to provide energetic molecules. As this organism (presumably) depends on ATP from another source, we depend on energy providing molecules like carbs, fat, protein.
Sorry I guess my question wasn't clear. I meant to ask, what is the source that those hygiene practices he mentioned are factors in the lower rates of spread of the virus given that other countries such as Italy and Spain have enacted stricter measures and yet show higher rates of spread? I am not asking for sources to show the difference in cultural practices.
Trump is already blaming china for not containing this, even though the us has equal responsibility to contain the virus within our own borders. Not to mention the measures taken by china to flatten the curve were extraordinary.
1. There's an option to hide the names of the employees. It would replace all the names with random animal name + a color. It's great if you don't want to know which employees are falling for attacks.

2. I love the idea to actually make the employees create their own attacks, but seems a bit hard to do and pretty much time consuming for a company.
Risks are ever-present. Choosing a liberal democracy involves accepting those risks, and not just in terms of public health and public well-being. A society that guarantees perfect public health and well-being would be unlivable.

Various forms of authoritarian government are well known as being able to respond to crises quicker and more effectively. So, yes, being able to declare a state of emergency is an important ability, but living in a permanent state of emergency is to be avoided.
I think to make a solid argument one way or another, one needs also to take into account medical and scientific opinion regarding the number of people that are going to die in the longer run because of economy stagnation.
Energy sources for off-grid living
One recent headache I had, I had to download JSON files loaded since yesterday's (about 15k) using python. The issue is that the bucket had 20+ million files. The naming convention (folders) wasn't perfect unfortunately. There wasn't a way to do this filtering on the server side. I had to download the file list with the metadata and then make calls to get each file individually based on metadata date.

Not a smooth process.
I'll throw my voice in that "screen" 100% refers to GNU screen in my friend circle. Tmux and dtach still don't quite supplant the specific slot that screen has occupied for decades.
Even today, the iPod hardware is excellent and long-lasting; if you ever need a portable music player with a long battery life and that's great for hacking, try getting a 5th-generation iPod Video and upgrading it. It's fantastic: in a matter of weeks (shipping takes time), I made a 256GB iPod Video that could play nearly any format (Ogg, FLAC, WAV, MP3, etc.) and that has an over-24h (I've not been able to run its battery down yet) battery life.

Its main advantage, though, is its ease of repair and upgradeability: an amateur with a plastic pry tool and a screwdriver can do nearly anything in a matter of minutes: replace the battery, replace the LCD (which are extremely cheap), upgrade or replace its storage, replace the headphone jack, etc.
“If you ask the American people to choose between public health and the economy, then it’s no contest. No American is going to say accelerate the economy at the cost of human life” - Cuomo

Unfortunately, this just isn't true. Is life worth living if you're destitute and living in poverty or emotional turmoil? Won't a strong economy increase the pace at which we develop and produce life saving technologies?

At a certain point of economic ruin, I think many people will choose a strong economy over saving lives. The question is more so what the tipping point is. It seems hard to quantify and compare the total impact a strong economy has versus lives saved, but I think it's definitely worth having the conversation. Ultimately, this is a value judgment so there's no objective answer.
Yeah, Evans' book really changed the way I do a bunch of design. That software is infinitely flexible is generally great, but it can allow complexity to metastasize. Anchoring design to the domain, which tends to be pretty stable, can provide a lot of clarity. It does require taking an anthropological approach to one's users, but I think that pays off in all sorts of ways.
For those curious as I was, Windows 10 1903 or later made it harder to disable Cortana. It's no longer in Settings and now requires a change in the Group Policy Editor (available to Enterprise and Education editions) or adding a registry entry.
What was expected to become a quick and decisive victory for the otherwise highly effective Qing army, ended in a stalemate.

This was a constant theme throughout Chinese dynastic history -- leaders at the provincial or national level underestimating the military capabilities of tribal peoples/"barbarians," rebels, and smaller tributary states. The preceding Ming dynasty is littered with similar examples involving Japanese-led pirate bands on the coast and tribal groups to the north and west. The 15th-century Zhengtong Emperor decided to take part in crushing one border flare-up with the Mongols, and was even captured. The dynasty itself was ended by Manchu invaders in the mid-1600s.

I don't believe the Ming ever trained a distinct/elite group of special forces as described in TFA, but innovative and effective generals were sometimes given special commands and employed new modes of training and tactics but using regular conscripted forces. The aforementioned Japanese-led pirates raiding the coast were vanquished in this way.

I recommend 1587, A Year of No Significance: The Ming Dynasty in Decline by Ray Huang (a historian and former military officer) for anyone who is interested in this topic.

> For instance, in a space of less than one roll of TP, canned meats can supply you with a day's worth of calories - and they're just halfway on the kcal/kg scale

Right, so, let's say 2 cans, one roll; two days, one roll. One month, 15 rolls? No. "Halfway on the scale"?" One month, 7 rolls? Maybe more likely, but I'm rounding up at every stage here, and granting you're eating only mayo.

The math just doesn't come close.
Thanks for sharing! This resonates strongly with me.

One thing I did (and fairly recently too: https://github.com/alefore/edge/commit/6e93c2bb327f57d13d067... says just 10 days ago) is adjust my text editor (http://github.com/alefore/edge) to keep a log per file of all the operations I do on that file. I expect to use this to generate reports along the lines of "what files did I work on last Thursday", "how much active (for some definition) time have I spent modifying this file" or "on how many different days have I opened this file". Perhaps I'll also use this as a cluster to feed to the Bayesian filter ("I tend to edit file X whenever I edit file Y") that I use to optimize my autocomplete predictions/search history.

(I also plan to use this to see if I can find ways to optimize the types of transformations that I bind to my keys if I notice special patterns (e.g., when I do transformation X, I very frequently do transformation Y immediately after), but I haven't yet thought very much about how I'll do this.)

I'm somewhat curious as to how much value I'll actually derive from this. I tried the Quantified Self in the past but ... I think it suffers from the fact that reality tends to be too complicated to be predicted by ~simple models.

Yeah. Basically the concept of species is bust taxonomically and largely a social construct at this point. (That is to say, what is a species is what the community agrees to be a species for the sake of convenience)
The guy mentioned has quite a significant online profile. He runs a startup that just raised quite a bit of money and I heard about him before I clicked the post.

Not going to link (tbh, anyone can probably find this guy/his picture/videos online) in case this turns out to be a case of mistaken identity (the guy who raised the money is 100% the guy Krebs is talking about...maybe Krebs is wrong though) but...if this is true...it seems that some well-regarded people really didn't do their due diligence.

Great idea! Yes, I think you'd have to give at least a cursory wash ahead if using the washing machine. I said washer mainly because mine has a very hot "sanitize" cycle though, so fouling shouldn't be an issue, especially if I add a little bleach to the load.

This argument is not worth responding to. You are arguing that our economy should be protected before people are protected. It is disgusting, and I'm tired of rehashing the same disgusting crap over and over.

If you really think that the economic effects outweigh the loss of life this virus can and will cause, all I can do is be glad that all you have is your ability to express your opinion, not the ability to do anything about it. Thank god for that.

Finally, and yes I'm quoting myself here "If you do not have another solution that keeps people alive, kindly be quiet; you have nothing important to say."

> Kindly keep the nasty comments about trying to dissuade me from discussing these important topics to yourself.

This is absurd; you're responding to me. And this isn't a discussion, these are opinions, with no facts to back them up. I simply find these opinions disgusting, as they do not prioritize keeping people healthy and alive.

Even on this site where people are somewhat more technically oriented than the general public, you see people who haven't a fucking clue what an exponential function looks like. NYS is expecting the peak 2 weeks from now. The numbers are Not Good. ICU's will certainly be overwhelmed and doctors will have to choose who must die. I don't think the healthcare system in NY will collapse but it will be tenuous even with the field hospitals they're setting up.

I think in large parts of the country where people aren't taking this seriously, the healthcare system will collapse and it will be awful. Especially if national leaders push to end lockdown very prematurely.

The article reads like they didn't even look for the boulder itself. Just that they made a brief visit to the island before turning around.

The "proving it was a hoax" part seems entirely down to the lack of available evidence that could be found before the trip was undertaken. The trip itself seems separate from that.
It's amazing to see how, when faced with the dilemma of "Industrial development, at the cost of have millions of people die", so many people want to follow in the footsteps of the USSR.

with regards to compounding rounding, is this not why we have significant digits? I haven't done physics in ten years so my memory is hazy on them, but I remember them being some control on what level of precision we can remain confident with.

Heads up- I made an edit that may make your comment seem off I originally had just responded "Medical and scientific experts" or something to that extent.

Appreciate your comment, it does make a good point. I think the difference is that virus deaths are more predictable than the economy as a whole, so if we know we can move one lever to limit the known damage, the desire to move to a nebulous and often partisan economic approach is a bit concerning for a lot of folks.
"Is life worth living if you're destitute and living in poverty or emotional turmoil?"

It sounds like you're saying you think maybe poor people should just die.
Curious why you're so opposed to spacer components. In my experience they work quite well--often a designer has specified that two widgets lie a certain distance apart, either vertically or horizontally, and the programmer needs to express that in code. Makes much more sense to use a spacer component than to add a margin to one or both of the widgets themselves.

If responsiveness is what you're after, you can easily make your spacers adaptable to different screen sizes.
