Hey, thanks for taking the interest and the time to audit and benchmark.

You can get a rough idea of VM startup time by running a simple hello world program.

fdir is supposed to compete against nodejs alternatives so I am not surprised it comes last. Maybe the next goal should be to optimize it against other cross language platforms.

V8 does a lot of optimizations but there is still overhead. A native solution in bash has little to no overhead so no wonder it's the fastest.

Anyway, thanks again. This benchmark was insightful (also humbling).
Your 'open web' analogy is just plain wrong.
I think this is important advice that needs to be repeated over and over and over again. The number of software developers who get caught up in the latest fashion choices, instead of carefully picking the right set of tools for the job, is absurd. Sometimes it's really important to use the latest thing because it solves a key part of your task; often it's better to use a "boring" technology that is well-understood and does the job without a lot of fuss.

I remember years ago, when I was in high school, reading advice that "customers don't want drills, they want holes". Software developers should constantly focus on what the customer actually wants (that is, the problem the customer is trying to solve).

It sounds trite, but it's easy to get distracted when you're knee-deep in trying to solve the problem.
Honestly most companies, not startups only, run on the idea that if you don't have debt, you're doing something wrong. It's not entirely false when the economy is neutral at least.
I don't even recognize the adjectives used. Might as well be randomly generated.
Looks like you do not need to be a New York citizen to join the effort, though this is the closest I found to confirming it:

> Given that many employers are having many workers work from home, volunteers would collaborate virtually with New York State teams. So, preference will be given to those in the Eastern and Central US timezones but we are open to the west coast as well.

The interest submission form does not ask if you are a NYer, but does ask if you're willing to participate on-site or remote.
Go to book fairs and industry events for the genre of book you are writing. My wife writes sci-fi novels and is an officer in a large writers' club (I think it's one of the oldest ok the country). Pretty much all of the members talk about how they really only make sales on their own at in-person events, even the ones with traditional publishers. My wife mainly manages to cover her costs with the sales, though we don't really go out of our way to go to really big events and have yet to do any sci-fi conventions. She sees a few sales on Amazon, but the peaks are usually right after we've been to a book fair.
I’m 100% sure. You can’t beat free.
Not only is health care regulated, it isn't even a market in the correct sense, because the people actually getting the health care services--patients--don't even know how much the services themselves cost. Which means that nobody is in a position to judge whether the services are worth what they cost. This isn't a market at all, it's a recipe for disaster. Which of course is exactly what we have.
NextDNS is a commercial entity founded by a Netflix employee who is working on a Netflix CDN. Do the NextDNS terms of use address the potential for data sharing between the two entities.

Running NextDNS has costs. Given the absence of fees for using NextDNS, it has a commercial interest in collecting information about users. Like other third party DNS providers (middlemen), e.g., Google or Cisco/OpenDNS, NextDNS supports ENDS Client-Subnet. This extension has zero value in terms of ad-blocking and privacy and arguably should be "off" by default unless the user asks for it.

PiHole is non-commercial project AFAIK, although they have registered a trademark.

Third party DNS caches will always be inferior to DIY in respect of certain issues such as ad-blocking, privacy, security, reliablity, etc. (I am a DIY-er and when third party DNS has an outage, the applications I use are still able to use the internet without any problems because I have zero reliance of third party DNS providers.) When using third party DNS these factors are outside the user's control. Users cannot tell third party DNS providers what to do, nor can they execute quality control, they can only accept what is offered to them. Of course, third party DNS will always be superior in terms of convenience and perhaps "features". I personally do not need all of the "features" offered by third party DNS, but I cannot speak for other users.

The user's "choice" between DIY and third party DNS depends on what is important to the user and what the user is capable of doing herself. When the user is not capable of running DNS software herself, then DIY is removed from consideration and the "choice" is simply between one third party provider or another. The user has very little control in that situation.

When it comes to DNS, for me nothing beats having control. For me, "control", not convenience, is the best feature. I prefer whitelist to blocklist. Every user is different.
Ouch those graphs indicate worst case interrupt latency in the 100ms range... that's one old article!
As I commented upthread, your solution is to just change the entire system of government. Sure, that should be simple. Not.

whenever someone mentions ender's game in a positive light i worry about that person

https://web.archive.org/web/20070206121131/http://www4.ncsu....

tldr; orson scott card is a bigot and ender's game is nazi apologia. if you don't want to read the above it's been written about in numerous places (google "ender's game book fascism").
What sweeneyrod said. Scala is also OK. It has advantage over both in some aspects, but loses in other aspects. Neither of Haskell, Scala or OCaml is _the best_ -- there just isn't the perfect language. Yet! :)

Features I care about:

* Type classes: Haskell, Scala

* Module system: OCaml, Scala

* structural subtyping / row polymorphism: OCaml

* Higher-kinded types: Haskell, Scala

Other important features, but not related to the type system:

* Powerful runtime system (multicore support, green threads, ...): Haskel, Scala (kinda, with the TypeLevel libraries, but still not 1st class)

* pure functional programming focus: Haskell, Scala (kinda, with the TypeLevel libraries, but still not 1st class)

* compiling to JavaScript (so that you can use 1 language for both backend and frontend): Scala, OCaml

... maybe PureScript would tick the most boxes ¯\_(ツ)_/¯
White Noise, by Don Delillo. It's a great story in general and reading it helped me acknowledge my fear of death and how it affected me.

Edit: oh, and since I don't think anyone else has mentioned them yet ... Riddley Walker by Russell Hoban, and Grendel by John Gardner. Their impact on me was less specific so harder to explain, but they're great books that get mentioned on HN now and then. Another one that kind of blew my mind is The Infernal Desire Machines of Dr. Hoffmann by Angela Carter.
I agree, and I'm basically trying to appease the hn crowd with the semantics. I didn't think my statement was controversial or incorrect enough to be hit with that many downvotes (I am an econ major - trying to balance layperson definitions with hyper technical ones) but clearly that ended up not being the case.
Plus, you don't have to use Windows on Azure. Linux instances are cheaper.
There is that; oddly some of those rich people are staying safe(1) all the while the administration appears to consider opening the US to the low caste Americans.

For the record, I have no intention of turning it into anti-rich tirade, but now more than ever people should be careful how they present themselves in public eye. In my view, pitchforks are a much closer possibility this time than in 2008..

How is it not an intrinsic trait? Is "bloated", "huge", "slow" an intrinsic trait of a software? If so then the opposite should be true as well.

The claims are true intrinsic or not and they are also claims other software developers classify different libraries with.
> My undergrad is very focused on self-study. Prof's have gone the the extent of saying, "I won't waste time showing you this, you could just go on youtube". Flipped classroom models are increasing and the focus is again, on self study.

What university is that? It sounds awful.

> But do you need to sit in a room with 1k people in order to learn calc 1? It's just the prof going through some examples on the powerpoint/overhead nothing more. Asking questions isn't easy either.

That's only kinda true of 100-level courses and massively popular generals, and quickly becomes false the farther you advance.

And even if it is a 100-level general, you can still ask questions if you're motivated and curious. When I was considering a career change, I retook general chemistry and a few other lower-level science courses as an adult. I asked a lot of questions, though many were picking at things that were too advanced for the course. You can't do that with a recording.
Show HN: Security Advice for Regular People
I had the idea to create a dedicated web page containing basic, easy-to-understand digital hygiene advice. So if a friend or relative asks you for advice on securing their digital lives, you can simply give them a link and hopefully they'll share it with their friends too.

Hosting is on GitHub pages; just a single, semantic, accessible HTML file.

I just made this today, so contributions are welcome, especially right now. I am not a security researcher, so if anyone finds an issue with what I've written in this first draft, or thinks some other point deserves mentioning, please tell me either here or in the form of a GitHub ticket or pull-request. Project goals and contribution guidelines are available in the readme.

I'm also thinking about getting a custom domain name for it, but I'm not sure what has the right balance of sounding trustworthy and being available/affordable. So let me know if you have any ideas on that front as well!

I don't think you can pick a single /r/medicine thread as evidence of a widespread problem. My wife and every other doctor to ever practice medicine can give you anecdotal examples of other doctors mismanaging patients.

Another thing to consider is this is a rapidly changing/progressing disease and there are no standards. The opinion of a recently graduated fellow has different biases than an experienced attending. They can both be correct while disagreeing on the specifics.
A friend who is a former epidemiologist, writing about some of his work in another place:

> Also, mine is a SIRD model (guess what the D stands for). People didn't use to include mortality in these because it depletes the population you are trying to simulate, but I've been able to run large enough numbers that you can include it as long as your disease is not too lethal ... and if it is that's also a result of sorts.

I feel bad about my last response.

I'm Scottish, living out on the west coast. We've had no cases of coronavirus here yet. Therefore things are not as bad here as they are elsewhere.

So, you should just read all my comments in your finest Scottish accent. I'm sure it will be terrible but at least it might give you a laugh.
Marginal cost is the amount it costs to produce additional unit of a good, cost overall would include fixed costs. Price is different from cost as well, since that's what people pay, not how much it costs (though in perfect competition price will equal marginal cost - but not the case in monopolies). These are nitpicky technical things but they do give you different answers when you do out the math.
Not to mentioned the prose ...

"For the height of this sort of deliciousness is to have nothing but the blankets between you and your snugness and the cold of the outer air. Then there you lie like the one warm spark in the heart of an arctic crystal. "
Yes, but you need to model it in the database. You don't even need to use the built in role system, you can use a user id that you pass into your database session.

Basically, create three tables: user, user_role, role_permission. Each user can have one or more role, and each role has one or more permissions. Permissions could be things like "view_admin_panel" or even granular like "view_project_with_id_5".

Then, you can create a row level security policy that does the right look up in these tables. I've not run this in a production system yet, but did successfully build out a proof of concept that worked. Performance seemed reasonable.
So the real question is.. what happens if you do not stop? As I stated before, most reasonable people allow for a lot of leeway to the government during a crisis, but.. the government response has been inconsistent ( at best ). I don't feel good about it at all. It makes me feel like Super Sad Love Story was basically a prophecy.
I came to say this. Some folks just have intermittant needs. I want to a remote hookup for Z minutes at x time from y sat.
I agree with you about the tools being in a data science course. What I'm pointing out is a lot of people have spent energy creating intro to programming courses but similar amount of effort has not been spent in creating intermediate courses that help people become proficient with the tools of data science. It's usually "intro" level content or library documentation.

I think writing code really helps you understand the algorithms in more depth so I'm all for exercises for LA like you suggest.
They do have some impressive "I didn't know anyone would need that!" services. I also love this one:

Does this regulation applies to the entire supply chain? Otherwise it might become unreasonable to produce some goods at all if component cost raises too much.

Forums everywhere end up with their own set of memes which are very effective thought-terminators. It's hard to stay engaged in serious debate in the first place, and even a couple people are usually enough to derail a discussion among "equals" to the point where nothing productive can happen.
A bit of a tangent, but how feasible is it for Starlink to crowdsource their ground stations? Let people contribute to the constellation by putting up antennas on top of their fiber connections (perhaps via solar roofs).

I think hard thing about Spacex is gonna be all the legalities across the planet of establishing an ISP. In some places it's demonopolised, but in some seems it might require to put up their own network.
lol this whole thread reminds me of the first time I dated a medical resident, carrying myself with similar confidence seen here, and quickly realized (after pissing them off with intensely ignorant statements a few times) I knew absolutely goddam nothing about medicine and how the human body works.
I highly doubt it. Ventilator operators are trained medical technicians and there is a lot of experience required to handle them correct, plus they're checked and supervised by ER/ICU doctors as well.

Article doesn't mention if he was actually infected by the spanish flu or if he just survived the times. Anywho, fun happy news, worth the 5 seconds. Maybe not hn material.

Edit:
Free from memory of a spanish flu documentary I watched the other day:
"As I entered the train, the conductor fell dead on floor. As the journey went on, I saw two more passengers die. Then the train stopped. The loco pilot had died, and I walked the rest of the way home."

Spanish flu was some heavy shit. With young healthy people dying the first day of symptoms.
Governments will also exert this force on behalf of their citizens, is the happier read. In a disaster, everything becomes finite, but profiteering is still deeply disruptive to the shared societal fabric.
I read a fair amount of Pynchon, but neither GR or the others jump out as having a "positive impact" on me. It's been too long, and I guess I'm not really clear on what that means. With some books I walk away with positive affirmations or a sense of better understanding. I suppose there was some of the latter, but not the same sort of catharsis. The world is dark and disgusting and confusing. I'd be lying if I said it didn't impact me though, which I'll grant, probably for the better.
Not necessarily the stock market, but yes of course all models are wrong. Some are useful though, including these models. You can see that a pharma company with a government granted monopoly with patent power has high gross margins, while a more undifferentiated retail firm like walmart has far lower gross margins. That understanding can be drawn from using these models to understand how businesses will behave under a set of given assumptions (they want to maximize profit etc)
All depends on the course of study and the people you're in it with and your own motivations.

I've done both for a very long time. There used to be value in going to the computer lab and spending hours and hours working through problems with peers and seniors.

But that doesn't happen anymore. I've learned just as much in slack chatrooms with fellow students at Georgia Tech, if not more.

If you want to learn, you'll learn. If you don't, you won't -- no matter what the environment is.
> economists and policymakers agree with your usage of monopoly power

Policymakers may; they'll agree with most definitions of a Bad Thing.

Economists have to be more careful. Saying Saudi Arabia has monopoly power in the oil market because it produces oil at a lower cost than other suppliers is crazy. What power they have to manipulate the market doesn't come from what they're already doing -- it comes from what they could do. They have a marginal cost of production which is below the current market price. The fact that their average cost of production is below the current market price is not relevant.

Consider a world where Arabia, Canada, Russia, and Venezuela all produce oil and sell it at the world price of $50 / barrel. In this world, Arabia's strategy is "pump all the oil we can sell at a profit". They have a marginal cost of production of $70 / barrel, above the market price, and an average cost of production of $20 / barrel, well below the market price. They're making money hand over fist.

No one considers them to have monopoly power here. What would it mean? How would they exercise it?

See e.g. The Concept of Monopoly and the Measurement of Monopoly Power ( https://sci-hub.tw/https://link.springer.com/chapter/10.1007... ), which would define Arabia's monopoly power in the hypothetical I've described as, on a scale from 0 to 1, negative 0.4.

But again, profits are determined by average cost, not marginal cost. There is no reason to expect average cost to equal marginal cost.
Maybe right wingers and xenophobes will finally understand why migrant workers are a thing. I doubt they'll appreciate all the work migrant workers do after all this is over, but hopefully the general populace will understand that voting for a bunch of fear-mongerers might lead to a situation where they actually have to pick their own produce.

Maybe it has to get worse before people understand just how connected the world is and that local actions do actually have an impact on the world.

I severely doubt it though...
