Makes sense and this definitely lowers the risk. However you could still end up with situations where the new method body assumes different constraints/invariants on field values than the old code, so calling the hotswapped method on existing objects could still lead to unexpected behaviour.

Example:

A class has a private read-only field int foo that can take any value and a DoStuff() method which uses foo's value.

Now the constructor is hotswapped to validate that foo > 5 and DoStuff is hotswapped with an implementation that also assumes foo > 5.

This is all good for new objects created after the hotswap - however calling DoStuff on objects created before the swap (which might have foo <= 5) is unsafe.

It's just a matter of parser implementation. These changes are backwards compatible. If python decided to add support for comments and trailing commas in json.loads, that would become the new standard, at least for data scientists, not for web devs. All the other ones would then follow.

Dune seems more like the middle ages in space, specifically the period of explosive Muslim expansion starting in Medina in the 630s. The empire he describes reminds me of the Umayyad Caliphate with a distant Emperor (Caliph) ruling over fiefdoms spread acrss the Mediterranean basin and beyond.
I am interested in how well even smaller communes have scaled through time and not necessarily through space and population size. One force that works against communism is the tendency of people to favor their progeny when allocating resources. Is there good documentation or history on communes that survive through multiple generations?

I think they're fine if you have lots of information to digest and you want to see tidbits about something else.

I came across this thread on my Twitter, was interested, so read parts of the linked complaint myself. I don't see what is bad about that?

Now, linking to the thread on HN seems dumb, I'd prefer something long form.
“ I must read this, learn that, keep tabs on who’s who, and never overlook any chance to compete for research-project funding.”

This is the mind of the modern academic. At least in industry I can feign incompetence at the politics side and my manager will handle it for me as long as I keep delivering the goods.

Not that it’s the best way to advance, but it seems there’s more opportunity to “be undeniable” outside academia, and I see this as the only way to not waste ones brain on politics.
Kudos to them. I remember reading a report from a game dev a few years ago that said basically the same thing and came to the conclusion, "... and that's why we're ending our Linux support," which utterly baffled me.

Google also runs their own public DNS servers which afaik Chrome defaults to. They can just sit server side waiting for DNS lookups of domains they've never seen before and queue them up for the Google bot. No browser telemetry needed.
All this just makes it clear to me that we need a time standard which addresses all the problems and of ISO8601. It’ll be painful until it’s universally adopted, but once it is we’ll be in timekeeping heaven.
Hmm, this comment certainly has its own passionate "depth" of criticism, associating millennials and "younger people" with serial killers.

I think you're still missing the point. Knowing system architecture is not more important than knowing how to read/write code efficiently, specially when you're not designing systems most (if not any) of the time. If you can't do that latter, you most likely can't do the former... this article is good advice for those who need it... once you know those things, you will have a much easier time learning higher level concepts and software architecture - and I, unlike you, find that those are actually the large majority of articles as they're, paradoxically, easier to write as you can bullshit your way through buzzwords and make empirically unverifiable outlandish claims about "microservices", "serverless", "blockchain" or whatever else may make you sound smart, without actually providing anything of real value.
Like depicted in that picture, no; close enough to work, probably. I can't do this ( https://openheart.bmj.com/content/openhrt/2/1/e000169/F5.lar... ) because the joint at the base of my thumb doesn't bend that way much at all.

I can't do this ( https://www.medmd.org/wp-content/uploads/2016/11/Bend-Your-T... ) because I can't bend the tip of my thumb while keeping my fingers straight. The index and middle finger bend with the thumb tip.

I can do what this picture describes as opposition ( http://i2.wp.com/boneandspine.com/wp-content/uploads/2016/09... ) with a combination of little finger movement and straight thumb or bent thumb and clawed fingers, and so I can make a fist with my thumb rotated around and tip covered by fingers.
Of course, most people haven't had smartphones for more than a decade at this point. (Certainly not much longer on the outside especially if you exclude Blackberries.) Not that smartphones are likely to evaporate anytime soon.
What is driving this trend?
No, it isn't. Most, or at least a very high percentage of independent truckers bid for cargo runs. Your cargo needs to get from point A to point B and weighs X amount and needs pickup and delivery at certain times. Truckers bid on the those routes and the the winning bidder gets the route.

If you don't want a delivery you don't bid on it or you set your bid high enough to make you want to take it. If no one bids on a delivery then the shipper raises the maximum they will pay and the process starts all over. Delivery location or pickup location a horrible place? Again, don't bid or bid high.

This is exactly the definition of a free market. Telling an independent that they must take the next load available without letting them decide if they even want it is not. That's being an employee. And shipping companies have spent years getting rid of their own fleets and drivers to push the cost to the individual drivers. And yes, there are a LOT of apps for this.

Why take the biased article at its word? Luckily we have access to all of these studies and can do the research ourselves (thanks Internet!)

https://ivmmeta.com/

The current count of medical studies that show Ivermectin being beneficial for treating or preventing COVID-19 is 64. Out of those 64, 44 of them are peer reviewed.

Or we could throw the baby out with the bathwater because this article cherry picked a few of the worst studies to shape a narrative.
To those of us (most of us) from a liberal background, I think governance of these kinds can be confusing. We look for legible rulesets and interrogate them with "what happens if." At a second level, we look for legible dynamics like the influence of group size you mention.

None of these are wrong but they're not necessarily key to the character of the system. "Consensus," meaning something more complex than "vote until everyone agrees," is a pretty natural way of making in tightly knit groups. We do it without realising we do it. Some people talk. Some agree. Some object. People talk some more. Usually, a consensus forms.

It's voting or other formal authority systems that need to be invented. They don't tend to exist by default. Not every culture has voting. Every culture has talking until a decision is made.

Consider jury systems. These are pretty formal, but they do have some consensus as part of the system. This is premised on jurors spending a lot of time together, discussing, argueing, etc.

Anyway, my point is that the most important parts are probably ilegible. A functioning culture forms, or it does not. The right governance rules or group size, with the wrong group of people will not work. The reverse probably will.

@Animats said > A place that just stacks empty containers 2 high probably only has large forklifts. The special equipment for high stacking is far more expensive, and only bought if you need it.[2]

Some facts:

1) Container Height: 8'6". Add approx 4" for the lift slots on the bottom.

2) Forklift with 22' lift available from Sunbelt = 3 Container Height / 50% increase in yard capacity https://www.sunbeltrentals.com/equipment/detail/1044/0550320...

3) Common "construction" type forklift with 39' lift from United Rentals = 4 Container Height / 100% increase in yard capacity. https://www.unitedrentals.com/marketplace/equipment/forklift...

And United has forklifts with even higher reach available.
> Is it crucial and it's a crime against humanity for being suppressed? Maybe, and I'm inclined to say probably because the same people who lie about everything are mighty certain that Ivermectin is something that doesn't help covid and anyone who says otherwise is a horse paste eating moron.

It is truly an indictment of our time that this is deemed a useful standard of evidence.
What if I told you I don't watch any of these 24/7 news channels because I think they are all garbage that share an agenda of making you very afraid and glued to your chair? Just last night my Biden NIMBY neighbors went up my street to warn us all of the imminent danger of the atmospheric river that is about to destroy the neighborhood (a suburb nowhere near any sort of flood zone).

I try to get my news from online and print sources ranging from slightly left of center to slightly right of center. It is becoming increasingly difficult to find slightly right of center sources of information because that's just not profitable anymore.

What is egregious to me is that all the curated news is now hiding behind paywalls but the sensationalist crap spanning the entire political spectrum is as free as the polluted air and the tainted water. Which is the way we all want it, well we get it etc.

It seems that in America, we attach too much of our identity and life's purpose to our occupation. It's no wonder that people have a hard time in retirement. The embarrassment of retirement comes from some fear that one is no longer useful to society.
I think the seeds of a happy retirement are planted much earlier. You have to cultivate interests and relationships outside of your career. I plan to approach retirement as a swap where my paid career becomes a hobby and hobbies become my full time occupation. A soft transition will hopefully make this easier and more fulfilling.
‘Utterly disgusting’: Fauci caught up in ‘cruel’ experiments on puppies
I have a Lenovo Thinkpad L380 and it's the worst laptop I haver ever owned. When I put it on my lap and I hit the wrong spot, it freezes and only turning it off and on again fixes the issue.

I sent it to the Lenovo support center in HK once, but the problem has never been fixed.

Long story short, as a guy who moves a lot internationally, Apple and Lenovo are the only companies offering global warranty and after my horrible experience with Lenovo, I'll be back to Apple!

Thinkpad quality has been terrible after the sale to the China-based Lenovo.

Maybe my experience would have been better with the T or X series though.

Calling C from Python is very different from calling Java code from Clojure. Clojure always runs on it's host (Java/JavaScript), so calling functions via interop usually speeds up everything with zero overhead, compared to calling C code from Python which does introduce overhead.

Everything in Clojure comes from Java, it's unfair to compare it to "performance is coming from C, not Python" as Clojure works differently.

No one at YC thinks of HN that way. I certainly don't. If we did, we'd run HN very differently.

You're also wrong about why HN exists. pg created it for a bunch of reasons. Some had nothing at all to do with YC (e.g. wanting interesting things to read, once Reddit stopped being that for him; and wanting to make a web app in Arc) and others did. All of those reasons are still alive today, so your interpretation is much too reductionist.

It's true there are job ads for YC startups, and Launch HN threads for YC startups get placed on the front page (this is all in https://news.ycombinator.com/newsfaq.html). I'd like to hear what you think we should do instead. Surely you don't think HN should give nothing back to YC in exchange for funding it?
Sounds like terrible design if that's necessary. Also absurd that the owner can't re-sign hardware given that they should have a master key.
> unnecessary luxury

as en expat living in amsterdam i couldnt disagree more. a city with a bike first infrastucture is incomparably safer, quieter and more pleasant for everyone in the city.

when it takes 15 minutes to get anywhere in the city using the bike infrastructure, one would be crazy to pull out the car and look 30 minutes for parking places that cost north of 7 euros an hour.

"people dont bike in bad weather and in winter" is nonsense garbage from people who dont live in biking places. if the infrastructure is there people will bike even in snow (https://www.youtube.com/watch?v=Uhx-26GfCBU).

> just take the bus if you don't want to drive

i dont depend on any public transport if i have my bike. it's the exact reason why people choose cars over public transport.
The user wants convenience, and then, under the premise of convenience, corporations create systems that give them the convenience they want in exchange for their privacy and freedom.

Until the forced update interrupts your game, that is.

Anthony Fauci Facing Quiz over NIH Funding for 'De-Barking' Beagle Puppies
The somewhat remarkable thing to me--and maybe it reflects how large dominant companies can be very resilient to market changes and competition--is that, under Nadella, Microsoft has been able to largely thrive. In spite of basically losing mobile in multiple form factors and device types, to say nothing of search, maps, etc.
It's a different technology. Just because we use the same word for it ("vaccine"), it doesn't mean our knowledge about e.g. the polio vaccine is applicable also to mRNA vaccines.

Partially.

The problem with Apache Arrow and Parquet is that you have two - one for storage and one for computation - but in the end you only want one for both. You want to run fast algorithms on memory mapped compressed columns. Not doing this stupid deserialization from parquet to arrow.

Parquet and arrow are designed by committee and try to accomplish too much for that matter. While that's good for some cases, my prediction is that there will exist a data processing system in the future whose file format will support that and be good enoigh for most data intensive applications. It will not be feature complete, like json, but will be good enough. Some devs from then on will complain about adding this and that feature to that format, but majority will be happy as they are now with json. Such format can only come from industry, not from a committee.

Isn't saying there is a need for centralized trust (regardless of an actual basis) logically the same as "we need to support delusions because the delusions are widespread?" When support of such delusions and establishment as norms are why they are so widespread in the first place.

Sure, some people get too frail, but in general being in physical shape is NOT a requirement to cycling as a means of transport (as opposed to a sport) in the Netherlands. Especially e-bikes are helping out a lot in that regard.

The question is a little ridiculous to me to begin with: you are too old once you can’t get the pedals round. If you can move a bike forwards you can participate in Dutch cycling traffic. There is no distinction between the two.

EDIT - But just to clarify: many people cycle well into retirement. We’re talking 60-70+ stopping ages over here, easily.

EDIT 2 - Here, have some governmental data: https://www.government.nl/binaries/government/documents/repo....
It doesn’t say anything on bicycle use in older age, but it does show you that average speed goes down by age. Average trip length does not however. In general it’s just an interesting read though.
Yes constantly.

I think it helps to specialize more as your career progresses FWIW. I specialize in search, etc, so constantly get emails about new positions to do some smart thing with Elasticsearch or some such.
Yes, but in most cases GraalVM would be a preferable choice (https://www.inner-product.com/posts/benchmarking-graalvm-nat...).

All of them refer to heavily confounded data (e.g. no medical history) and I'm having difficulties finding more thorough studies.

Are better analyses available/underway? Thank you!
