Just because Khan Academy teaches it doesn't mean it's the most effective, most useful, or even correct method. They too are victims of needing money. Teaching what is currently being taught has been their bread and butter since the early days.

I can only speak from examples I've seen from young ones in my family "acing" early math and suddenly struggling with trivial stuff like Geometry, more advanced fractions, factoring, etc.

Common tricks like so-called "number bonds", "colored numbers", excessively complicated math for simple arithmetic by using shapes, preferring "regrouping" to carrying, etc.

All of these are valid, and with the correct level of sophistication a student can learn these tricks fast and use them correctly. The issue is you're dealing with kids who haven't gotten any sophistication yet. The reason things are initially taught rote is not because of some shibboleth of mathematics but rather mathematics can be useful without always knowing exactly why something works. There are some examples of common core problems floating around the internet that border on introductory number theory. The premise of it is ridiculous. Your child arrives to high school or college with a cobbled together book of poorly learned tricks that end up having profound influence over their ability to digest actual complicated math.

To drive the point home a "common core" version of calculus would have you learning real analysis long before you even understood a derivative. It's asinine.
I still don’t see why a computer program necessarily self-replicates. You can program it to do so, like a computer virus, but a supremely intelligent one could override its programming.

That is my source for concern, because any such program would have to find self-replication to be some universal “good”, and not just a property of certain dynamical systems like viruses, bacteria, and eukaryotes. And I can’t see any reason why it would, tbh.
Yes, version string comparison is hard because people have all sorts of unstandardized ideas about version strings. Not sure why you seem to believe there’s golang-specific difficulty here.
> If our government was elected based on a "one person one vote" principle, Republicans would be nearly guaranteed to lose the presidency and Congress.

The Republicans are competing under the rules that exist - and they’re very, very good at it. Do you think they would blindly wander from defeat to defeat without seriously changing tactics?
This was my experience at caltech, too. The open campus was really fun to be on with the tourists and the old people, and the buildings were like a science museum.

My funniest memory of this was taking a picture with a Chinese tourist while standing next to my photo on a bulletin board.
Yes I’m sure that Apple’s 95% retention rate is based on iMessage based on the sample size of “people you know”.
Actually, everyone is underwater on RSUs. We do 4 year vesting so even people who started 5 years ago are vesting their stock from 4 years ago.
I'm querying siri on a homepod, not a phone. And I just checked - she still answers with a weather report near "Sidney Tools". (Its currently raining and 17 degrees C, if you're wondering.)

I have a running theory that you can tell how long any FAANG bug will stick around by just imagining a 25 year old tech dude in the bay area. If Dave the bay area tech dude will never encounter the bug, you're in for a bad time.

For example, google maps used to give terrible directions at roundabouts (traffic circles). That makes sense because there's no traffic circles in the bay area. All the people who could fix the problem weren't aware there was a problem at all. Dave is terrified of roundabouts, so of course it took about a decade for directions at roundabouts to improve.

A corollary of this is that modern software works well proportionally to how closely your setup matches that of the average bay area tech dude. Everything works best if you have a new phone (preferably an iPhone), fast computer and you speak english. Woe be to you if your computer is old and slow, or you use a right-to-left language, if you're blind or you have a bad internet connection.

Macos feels laggy and slow on a slow internet connection because of course it does. Bay area tech bros are never in that situation! What would Dave know about slow internet?
Yes, and once we answer the question "How come Twitter is the centre of culture for monetizable users yet appears to be unmonetizable" we'll have the answer to why twitter's stock price has been stagnant for years.

Personally, I think the answer is "twitter is popular because it isn't monetized, when it gets monetized it won't be popular".
Conceivably, a state actor could use this bug to eavesdrop on an espionage target, no?

Well, let's try to conceive it. Our state level actor is now in possession of an exploit that lets them eavesdrop on a target when they text-dictate or activate Siri, while wearing particular Apple headphones. After getting the target to install a specific malicious app from the App Store. And to run it. And to give it Bluetooth permission. And to make sure to restart it whenever they reboot their phone or the phone kills it for any reason. The value of this as state-level actor surveillance malware feels a lot closer to $0 than $7000 to me but I'm happy to hear a different conception of how this might work.
I’m currently playing it on Windows, 7 or 8 hours in. I’ve had 2 bugs so far that required a restart.
> What I'm saying is that I don't actually think Tesla or Elon has suggested you use Autopilot (or Full-Self Driving Beta) in any way other than the approved way.

Tesla does that quite regularly.

Population shifts mean an ever-shrinking minority of the population can block changes to the constitution. It’s barely even double digits at this point.

Constitutional amendments were supposed to be easier than right to rebellion. That’s not really the case any more. At the same time, the supreme court is just ignoring the law, over the objections of 66-75% of the population (depending on the ruling).

These are dark times for US democracy. There’s no evidence things are working as intended.

Yes. And the issue is, that's not an acceptable stance for a language seeking to be a systems programming language.
Even with wormholes? Brute force traveling (aka using pure speed) may be a fools errand but we may still have clever ways to bend (pun intended) the universe to our will.
You can buy rifles and ammo in the same stores as milk and eggs here.
I'm also wary to use programming languages as a metaphor to advance a view about writing constitutions.

I can agree with the broad point that inertia is a major cause for constitutions to stay the same over time. But I disagree with the original commenter's implication that more recently-written constitutions tend to be better than older ones due to lessons from the past, because of the idea (perhaps relating to yours) that contemporary political and ideological considerations can introduce weaknesses into more recently-written constitutions, which overlook potential lessons from the past.
If at times the Constitution is not responsive enough, it does have one big benefit: it is almost impossible to change it to do something like, allow a President to serve life tenure, and yet we see a number of places where such constitutional changes were pushed through by those who would be dictators, or sought more powers as executive(Russia's in 2020, China in 2018, Ecuador in 2016, Turkey in 2017, etc.
A conspiracy theory is, by definition, a secret. That the government routinely ignores the Constitution isn't a conspiracy, just a sad fact. How many wars have we been in over the last 70 years? Vietnam? Korea? Iraq? Afghanistan? Just to name a very few. Read Article 1 Section 8 of the Constitution. How many times has the Congress voted to go to war? Is this just a conspiracy, or another example of our government's disregard for the document that purportedly grants them their legitimate legal authority? Congress actually voted against going to war against Libya in 2011, but Obama ignored them and destroyed Libya anyway. Conspiracy or disregard for the highest law in the land?

> And if you have a modern condensing gas boiler it is considerably more efficient (over 90%) to burn gas in it than use electricity generated in even the most modern and efficient gas fired power station.

If your grid is low carbon it might still break even (it will cost you money though).

This is all relatively pointless minuitae though. The main advantage is it's faster so one should do it anyway as there's no downside.

Unrelated, I've always been fascinated by the idea of a solid state heat engine driven kettle. Peltiers are so inefficient that it's not really pointful even as a toy though. I keep waiting for magnetothermal to be a thing.

> without any clarification it is a future promise

and even then, oftentimes it's -very- strongly implied that if it's not really available now the only thing holding it back is regulators.

(Well, that's actually true in its own way, though not a good thing - I am certain that Elon would be yeeting all sorts of shit over the fence if the regulators let him, if only so Tesla could realize all manner of deferred income.)
I often wonder why people don't use SI prefixes for money.

Xi Jinping is feeling his age. He wants to be the one what got Taiwan. Soon enough he'll try for it, just as Putin has tried for Ukraine. Age is catching up with them both.
I discovered E years ago and always lament it never had a resurgence. Coming from Scala/Akka, I adore message-based/actor systems and saw the promise of E to that end. Maybe some day we will get a first class actor language. Swift is kind of trying right now but it still feels bolted on.

The author does not "complain these amendments cannot be passed because of political polarisation [sic]" - she points out that even prior to polarization most amendments couldnt be passed. There are many other important and nuanced points in the article as well, it's neither pro- nor anti- amendment.
Podman implemented Dockers REST API as part of either the Podman 3 or 4 release (whichever one is in Debian stable), and I’ve been able to use docker-compose with it since then.

Podman has fairly good support for k8s deployment configurations, which I’ve used as well, if you’re a k8s shop, but I understand there are a lot of places that have standardized on compose for development.

>If you use technology in 2022, it's reporting on you.

Categorically impossible statement to apply universally. I have several machines that do not have the physical hardware necessary for any kind of networking. I also have multiple machines that do not have ME fully functional. My most upstream local router, running open source firmware, has whitelist rules for outbound traffic and blocks by default. I also have detailed traffic analysis running 24/7 on my other routers, running different open source firmware. I regularly review for any traffic that I cannot definitively associate to my own activity, and I regularly mix and match the network route my devices take outbound to look for anomalies.

>In your example you buy DVD's... where did you get them? How did you pay for them?

As opposed to copying a friend's discs, or receiving them as gifts, both of which apply to a nonzero number of my movies and shows? What if I did buy them and paid in cash? Not cash received from an ATM or bank teller, of course, but cash received as payment from a customer at a farmer's market?

>IME isn't the only privacy hill to die on... and frankly, that hill already has too many bodies on it.

Privacy is somewhat like security in that you're never truly "done" implementing it. That's not an excuse not to strive for it. While it remains unproven that ME/PSP actually is a functional backdoor, there's no good reason to trust these subsystems. I have personally observed Ryzen-based systems attempting to send outbound traffic while the system was hibernating (before you ask, I will not reveal any metadata about this traffic publicly for obvious reasons.) I know I personally would gladly pay 3x MSRP for Ryzen chips without the PSP. I know many other people who would pay well above MSRP for modern Intel/AMD chips that do not have these subsystems. Market demand is there. The fact that neither major chip producer even offers the option to purchase chips without these subsystems should absolutely continue to arouse suspicion.

You are correct that there are many other issues like writing style analysis, timing analysis (including netflow metadata being sold by your ISP to Team Cymru), many entire threads could be filled with software privacy threats, etc, but again - that's not good justification to just throw your hands up and stop caring altogether. Privacy is an uphill battle in a losing war in today's world, but I for one will not stop fighting. I have a natural human right to privacy, not granted by any man, nor a million men calling themselves a government, and I will stop at nothing to exercise that right.

To your point, that insistence does push me closer and closer to the "cabin in the woods" lifestyle than a vast majority would be comfortable with.
Ask HN: How long do take home coding projects take you?
I have had a number of take home projects for interview loops lately. On average they say that it should take about 4-6 hours, but I have found myself actually spending a about two days on it. The first day is spent understanding the problem space, which is often unique to the company's domain, and creating an MVP. The second day is spent refining and polishing.
Why does all the "nation building" around the world by the United States never result in a US style constitution, but seemingly inevitably in something closer to the German one?

I mean, Americans always talk about their Constitution's supremacy, but they never want to give it to others (not even to Puerto Rico).

You either don't know many programmers, or they're not being forthcoming with you about such personal matters.

“decade” is quite optimistic.
Would that allow them to cache the full collection at multiple resolutions? I expect not.
This is why I like the “lame” gifts.

Once I got a towel. Only one, but still, I needed to get some new ones and now I get to delay shopping that while longer because who wants to buy towels? Awesome.

People always think of gifts as fancy stuff. But if you can save me some time, or feed me, fantastic.
It's not about getting the best, it's about finding that which establishes the relationship, in particular that you know them, remember what was said, have shared experiences. Example:

Someone I was fairly fond of was retiring, a few levels above me. Traditionally, items are given. I gave an autographed copy of a particular book (we discussed it in my job interview over ten years prior) which related to our profession, a special dessert one (from the area in which she served in the Peace Corps), and a bottle of dandelion wine (her favorite author was Bradbury, who just died, and who authored Dandelion Wine). These went over well, despite not being the rarest of books or the most expensive of wines, but because of the dependence on and acknowledgement of my knowledge of her.
Crushed it!
> If you had or have children at university, do you really want an open door policy with non-students allowed to go where they want on campus at any time without appointments or permission and unescorted?

Dear god, yes. University without an open culture sounds terrible and pointless. Might as well send your kid to some sterile LAC and put them out to pasture.
I didn't claim that. It's just the main reason for not switching according to my friends. The imessage moat in the US is pretty heavily discussed on here.

It’s not that widespread. For international payments, you can do international bank transfers which have fees associated with them which can be shared or put on one side of the transaction only. It’s often easier and cheaper to use a 3rd-party provider like XE or TransferWise.

This. I hate getting books as gifts because I am lucky about the editions I buy nowadays. People used to gift me books until I asked them not to. I'd prefer it if someone asked me what I wanted and got me specifically that, unless, of course, they made me handmade cards or bookmarks.
… and it will happily fly you into a construction crane that was notam’d a couple weeks back ;)
Fair enough, but you're not me. It's not just campuses, everywhere I go, I am persona non grata.
“Democracy” isn’t a one-dimensional issue. How you make decisions (majority vote) is one dimension. But who makes the decision—what group does the voting and is bound by the results of voting—is another dimension. Many countries balance these issues by having different levels of voting. Distinct communities wishing to govern themselves is a nearly universal phenomenon. My country exists because we didn’t want to be in a body politic with Pakistanis. It was our right to decide we should have our own government where we, and not they, voted on the laws that governed us. Dismissively comparing all such impulses to the Civil War is intellectually lazy.

Self determination is a widely recognized political right. If folks in Alabama don’t want folks in California to have a say in their affairs, they have that right. That must be balanced against other practicalities of course. But letting different groups govern themselves is conceptually part of “democracy” just as much as “one person one vote.”
From my perspective, vim is just a tool that I picked up in college, back in the bad old days (early 00's) where good IDE's were paid and anything free was largely terrible.

Sure IDE's are great, I love stepping through code, it really helps when you're in deep and are having problems reasoning about the state of your program.

That said, every shop I've worked in used a different IDE. Possibly one picked out by some long gone coder who thought that their choice was the best.

Finally not being saddled to any one IDE lets me use the any other tool to get a job done.
> Why does all the "nation building" around the world by the United States never result in a US style constitution, but seemingly inevitably in something closer to the German one?

Then again, US nation building tends to be an abysmal failure (though, tbf, constitutional structure is not high on the list of defensible reasons for that.)
If anyone finds "a standard library string comparison function, while quite fast in absolute terms, isn't as fast as it could be" to be practical justification for a fork, I'd be very surprised.

If we used a nationwide popular vote, the GOP would just run someone closer to the median of their House delegation, which consistently does win the popular vote.

Sounds pretty great to me.
There are a lot of comments here about how the founding fathers intended this or that as if they were a unified group of people with a single vision. This is far from the truth. The original attempt at a governing document wasn’t the constitution, it was the articles of confederation, which failed. The constitution was a compromise. Some wanted a king, some wanted direct democracy and there were people in every shade in the middle.

I read an autobiography of Benjamin Franklin today. He spoke highly of a religious sect that refused to write their laws down. They felt it was absurd to think that they had come up with the perfect laws that would govern all future generations. If they wrote it down, future generations would consider it sacred and would dogmatically enshrine those views rather than improving upon them. Ironic that we do the same to him.
Perhaps the idea of the submitted article can be amended to account for your experience.

If a person has a friend that is into coffee, that's great news because you know your friend has a clear interest, but additional research is needed to make sure the gift is high-quality and redundant. Maybe 15-20 minutes of research on a specialty forum like r/coffee (at least the wiki) or a reputable YouTube channel (like James Hoffmann's) can help the gift-giver understand how to find quality beans (often light-to-medium from a smaller reputable roaster). If there's uncertainty, one can either directly ask the friend or make observations.

In the end, perhaps the best gift isn't so much the coffee beans per se, but the thoughtfulness you take in the person's hobby as you can then develop a shared interest.
> I don't know of any energy source that will last 20,000 years.

Maybe not as such, but I think indefinite self repair is pretty much within reach of modern technology, if we put in the engineering human-years. Build a vessel with redundant power sources, so you can turn one off to repair it, some parts fabrication, and good recycling, and it'll at least have a chance of lasting for the long haul.
I doubt any civilizations capable of robotic interstellar travel would consider unleashing a Replicator-esque paper clip maximizer into the universe a worthwhile pursuit.
