>> it also meant that reading comprehension on standardized testing was laughably easy

I'm actually curious to hear how various HNers have done on on standardized reading comprehension tests. I grew up with massive bookcases in the house, I've now populated my own, I read a lot, get a lot out of it, and enjoy it. On the ACT I had perfect scores on every category but a literal 0 on reading comprehension. As far as I'm aware, that's always been the case on my standardized tests, and I wasn't surprised because the questions seemed ludicrous to me (I nodded vigorously while reading [1]). I primarily read non-fiction and have wondered if I just don't grok fiction. What are other people's experience on that?

Already Freakonomics noted/claimed that reading to kids makes little difference to educational outcome, whereas having lots books at home matters. The following explanation (taken from https://abcnews.go.com/WNT/story?id=1633286&page=1) was given:

"Well, no," he continued. "Much more likely is that any family that has 100 children's books in the home is likely to be pretty highly educated to begin with, is starting out with a pretty high IQ, and values or treasures or rewards education to begin with."
It would be fun to have a small electronics package that could turn some of these designs into RC flyers.
But it isn't; some pretty fantastic bands who have a great live ending to a song end up having a fade out on the album from time to time.

Here is one: https://www.bilibili.com/video/av14050662/

That song has a lame fade out on the Glamour album [1988]; what a waste. Love this live ending!

The WORST imho are the sites that ask for notification permission, to which my initial reaction is FUCK YOU... there's no call for that without a user initiated action.
There's no legal burden of proof requirement for firing somebody for suspicion of belonging to a non-protected class.

American libel laws also require that, to convict someone of libel, you need to affirmatively prove that the defendant's claims are untrue, particularly if the victim is a public figure.

The real problem with McCarthyism is that even actions by non-governmental entities to enforce social norms against genuinely totalitarian ideologies by means that fall within the bounds of the law can still be unjust if they are pursued to extremes.
There are definitely health risks. Look at all the bottles that have the "BPA-free" disclaimer on them.

Over the last two years I made a lot of paper aeroplanes for my nephew, after that I started to build my own glider planes and now we're into RC planes.

My house didn't have that many books (less than 100), but I didn't have a computer (I'm from a developing country), so when I got extremely bored I just picked up whatever book I could to keep myself entertained for a couple of hours. This is how I fell in love with Asimov's stories and eventually got into programming.
Why does salary and experience stop correlating after 9 years?
I'm sure no one would ever admit it, but I'm like 75% positive Amazon did the same thing on Etsy when they launched Amazon Handmade.

75% because I'm just recalling based on some forum posts I read around the time they launched, which of course I might be mistakenly remembering or interpreting incorrectly.
This article smells. Like a bad code smell.

Especially since we have the Chinese government freely admitting [1] that they will restrict travel to regular citizens for "spreading false information about terrorism, causing problems on flights, using expired tickets, smoking on trains, failing to pay social insurance or failing to pay fines", according to the National Development and Reform Commission’s website.

> Cutting edge features are proposed way earlier than commercial DBs start thinking about implementing them

Definitely not true. Postgres development is slow, deliberate, and the opposite of cutting edge. It's what has lead to a great platform that is reliable and flexible, but every single commercial database out there has far modern tech implemented.

The web was far more useful for you. I, for one, am glad the days of IE6 and the lot are over.
Also because metformin (last I heard) is considered exceedingly safe and almost universally beneficial--so much so that some recommend prescribing it to everyone over a certain age.
I've had a similar progression. Have you gotten into discus launch gliders?
Fair enough, I'll admit the line is a little fuzzy. But there's clearly a point where we've gone way beyond any reasonable notion of "defense" and are engaging in offense, oppression, empire building, etc. And I'd argue that we're way over that line these days.

What was the range of the Mosquito compared to the Lancaster?
I view it as a trade-off for excellent man pages. Rather than waste time figuring out what the appropriate amoutn of and commands to list in the short help list (especially for commands that might have a lot of and/or complex options), they have very simple rules. List switched with help, list everything and very clearly in the man page.

Since I believe they don't accept code patches without relevant man page patches that explain them if they alter the behavior or add/modify an option, this seems like a sane way to avoid bikeshedding on what is essentially superfluous information, since the "appropriate" amount of info to include is ambiguous.

Read the manpage.

One thing I really dislike about modern UNIXes is their lack of decent manpages in place of standins like --help.

I love the BSDs and especially OpenBSD for their attention to manpages. It's the main reason why I don't use Linux anymore unless I have to.

Adding detailed --help messages would take time away from maintaining manpages, it also presents a duplication of information. If you want to know what the switches do, read the manpage.
I don't know how long ago you used it but that's exactly what I'm doing right now. The files just have to be on the Windows file system. I edit with Visual Studio Code and use WSL (Ubuntu) to manage the repo.

In the next version of Juniper everything will be moved over to purely stack based allocation. Currently only function closures and refs are allocated on the heap. The refs are only created once when the program initializes itself, so that isn't an issue. The closures will become part of the function type. The FRP model works very well for the Arduino platform since you're essentially modelling a data-flow from input to output devices. Currently the compilation target is C++, which means that the Juniper compiler doesn't have a ton of control over the final assembly code.

Ask HN: Is Google recording our conversations to serve us with relevant ads?
I believe we have all been served with ads for products and services that we haven’t even searched for. I presented this question to our Google Account Manager and he told me that Googles machine learning has become really good at predicting people’s intent. Having dabbled in Machine Learning myself, I don’t buy his crap.

Furthermore, the real problem is cross-directional intersections when traffic is heavy. Assuming you need to give traffic in both directions roughly treatment, you're still going to have traffic jams whether the flow is mediated by a traffic signals or by this V2V communication scheme.

Roundabouts work better to keep traffic flowing in all directions, without complicated signaling of any kind.

indeed. dpdk uses this (and other techniques) to achieve 10gbps line-rate (at least) packet forwarding on minimally sized packets per (x86) core.
"event storming" and "knowledge crunch with stakeholders" are two phrases I've never heard before. Can you explain them?
Agree! That is what I've liked more about the post. The design is just great. Very good looking, simple, and clean.
The planes are nice too though :)
"Sprint" is a horrible term for an iteration, even if you argue that "it's just a metaphor". The metaphors we use help shape our thinking, and creating the notion that one can "sprint, sprint, sprint, sprint" with no end, and with no rest, is silly and harmful.

That said, we don't need to coin the term "relay". Just use "iteration". No need to over-complicate things.
I was intrigued by this device when I first read about it. This should be on the "alternative path" to MRR focused digital landlords, but instead it's just the same damn thing...? The rent seeking in this industry is disgusting.
It's not fair to compare the two. I love OpenBSD for use cases where I care about correctness, stability, security even at the cost of performance or the having the latest feature set. Firewall, DNS, HTTPD and the like.

However, when it comes to running scientific applications and squeezing out last bits of performance or servers where people expect stuff to "just work, and if doesn't do apt-get blah", it's Linux that takes the cake.

FreeBSD and ZFS - the best I've worked with for Network Attached Storage. Can't believe it is just free.
>We codify against pointless discrimination against protected classes of people for a reason. Some things are no longer worth debating and serve no purpose but to actively harm people. So no, they shouldn't be allowed to do that.

But where do we draw a bright line? Sure, maybe we want religious people baking cakes for gay weddings. But should Muslim bakers be forced to draw likenesses of the Prophet Muhammad if a customer requests it? Should a bikini wax establishment that only works on women be forced to wax the intimate areas of a pre-op transwoman?

When I would get in trouble as a kid my mom would ground me for a certain number of books. As I got older/wiser/in-more-trouble the requirement moved from # of books to # of pages and she'd test me on random sections of the readings. A++ productive way of dealing with a difficult child!
Whether or not other states "uphold" them is missing the point.

The point is that is is quite easy to get a job, and just not tell your previous employer.

You might find it amusing to learn that non-competes are generally unenforceable against attorneys on grounds that it'd be denying the client the choice of her counsel...
Interesting. I've always thought of variable pitch propellers as being more efficient by allowing the engine to stay at it's peak horse power. For a piston engine this is obviously at the peak of the nice curve you'll see on any dyno run. A fixed pitch propeller sized for climb would allow the engine to run above this speed in cruise and vise-versa if it were pitched for cruise.

Now an electric motor has maximum torque at 0rpm (stalled) and practically no torque at it's no load speed. The relationship in-between is practically linear. So long as the motor was matched and / or geared so that during all stages of flight the RPM stayed within a reasonable band I don't see what the advantage is. Maybe some second order effects of efficiency at lower speeds perhaps.

Edit: Actually, thinking again, it's the exact same reason that cruising at the lowest possible RPM for the required power output in a piston engine is typically the most efficient. Just less friction. Still think it'd be a smaller effect given we're talking roller bearings rather than plain bearings and piston rings.
We already have this. Traffic lights in a given municipal area are often networked and have sensors to get traffic data.

For example, McCain (a popular manufacturer of traffic controllers), has their own TMS (Traffic Management System):

What I don't think there is yet is any sort of neural network training environment for a TMS, but I might be wrong.

>to deride: to speak of or treat with contempt, mockery, or ridicule; scoff or jeer at

Is the Hollywood sign really the target of that much mockery? Caricature surely but that's not the same thing.
Agreed. Our local gypsies exchange the same babies on queues for social help and never have to be worried about not having money for food while I have to bust my health and reduce my life expectancy to not be thrown out of my rented flat and have food in the fridge. And I have to produce kids so I can help the world?

No.

I refuse to bring kids in such an uncertainty. I don't "owe" our civilization nothing. I can die tomorrow and it never did anything for me except demand more and more bills and trying to scam me into yet another loan or an expensive buy that I don't need. That civilization is not entitled to dictate anything personal in my life.
You can search for "PLA vs ABS" - biodegradable vs permanent plastics and the main players in 3D printing so there's a lot written for a laymen audience about their pros and cons.

LEGO is trying really hard to introduce biodegradable plastics into their product line and have written about the struggle to produce something that is as permanent as they want it to be (so you can hand your LEGOs down to your grandchildren) while making them from plant sources, which is different, but related.

But basically all the resin / petro plastics win out in strength, durability, UV resistance, etc etc -- so there's a lot of products that can be made from bioplastics but you won't see fiberglass boat hulls being composted anytime soon.
It's a combination of the command line itself, and the actual command line apps.

For me, this is the single biggest use case for thefuck:

$ git push
fatal: The current branch my-branch-name has no upstream branch.
To push the current branch and set the remote as upstream, use

git push --set-upstream origin my-branch-name

$ fuck
git push --set-upstream origin my-branch-name [enter/↑/↓/ctrl+c]

(enter)

I'm pretty unrepentant about that one - I _could_ waste brain cells on keeping track of whether my branch already exists upstream, and I _could_ waste keystrokes typing out the more verbose command myself. But I'm not gonna. Life's too short.
It is a bit nicer looking than ?option_a=1&option_b=2&option_c=3 etc

It's my intuition that salary increases with experience for that time until you have basically "capped out" what the market will pay for your skills. After 9 or 10 years, talent and skill are probably a more a factor than experience.

Another way of saying that would be the difference in pay between a 1 and 3 year developer would be pretty easy to explain on experience alone. But, the difference in pay between a 12 and 18 year developer would be more explained by their skills and specific experiences (not time).
Roundabouts take a lot more space and suck for pedistrians.

Every time I've thought about moving away from Utah, I've found it almost impossible to find a place with a better salary/cost of living ratio.

There are a handful of things to not like about Utah, but in the software industry at least, it has been pretty good for the last decade.
Thank you. I agree, and I seem to recall other comments to this effect, in the past.

The guidelines don't specifically mention URL shorteners, but they do ask posters to supply original sources:

https://news.ycombinator.com/newsguidelines.html

Please submit the original source. If a post reports on something found on another site, submit the latter.

Personally, and as a suggestion for this site, I would extend that to ask that sources not be hidden behind a URL shortener. I want to see where I'm going; I also don't appreciate my click being tracked.

I go "meta" on HN only reluctantly. But, I've noticed the increasing volume of comments on HN, and it seems worthwhile mentioning that HN has some different expectations than other sites. Expectations that have helped to keep the commentary elevated and on point, up to now.

(I'm just another poster, here. The only basis for my comment is appreciating the quality of discussion here, and hoping it continues. Thanks.)

P.S. Not sure why the downvotes, but ok. As far as I recall, there are many past cases where the use of URL shorteners has been discouraged.

Somewhat akin to the advice to stick [PDF] in the submission title for links to PDF files. People don't like surprises. Or, in my case, mystery links.

> American libel laws also require that, to convict someone of libel, you need to affirmatively prove that the defendant's claims are untrue

That's true, but potentially misleading: under the civil standard of proof (“preponderance of the evidence”), all the burden of proof means is that you are obligated to provide some evidence from which that conclusion could be drawn.

> particularly if the victim is a public figure.

No, while there are other things that must be proven when the plaintiff is a public figure or the issue is one of public concern, the degree of responsibility or required proof on the falsity element of libel doesn't change. (What does change, specifically, is about the publisher’s mental state; while for libel more generally mere negligent misreprentation will suffice for libel, for issues of public concern actual malice is required.)
True but in statically typed languages we have a lot of options now. It's interesting to see how c# and C++ have developed and what approaches new languages are taking. My own practices have definitely changed over the last 25 years, where I initially used class hierarchies to model my problems I now think in terms of interfaces. Also, with everything being connected I just don't worry about building large monolithic systems composed of class libraries any more.
I always found that the reading comprehension part of the test as the easiest by far, and would generally score at the highest level the test could predict.
You did? It was broken down into types-of-failure and each type of failure had examples/hypotheticals of where this type-of-failure led to bad outcomes.
I run OpenBSD on my router and it's great. It was refreshing to not need Google for figuring out how to set things up, because everything is in the included manual pages, which often do a great job explaining new concepts. Want a quick intro to OSPF? man ospfd

I don't think I'll run OpenBSD as a desktop OS unless performance drastically improves, but it's staying on my router for the foreseeable future.
