> If humanity's greatest weakness really is our failure to understand the exponential function

If this is in regards to dismissing coronavirus concerns, I don't think that was the problem - more a case of people assuming the exponential growth would be magically stopped earlier by some governmental force or whatever.

When the first case in the city I live in was announced, I remember thinking to myself, it's just one case, they're now quarantined and they've probably done proper contact tracing and the country is preventing people coming in from infected regions abroad. I was perfectly aware how quick exponential growth happens, but to some extent had faith that "the system" would prevent it from going out of hand.
Ok IPV6 is one of those ideas that was obsolete by the time it was deployed. 12 bytes? Why not 16? Why not a UUID for each node? No management; no guessing who's is who's. Heck, use a new one for every connection.
> If you’re trying to understand how much a new deployment on AWS is costing you, and find ways to optimize that, you don’t care about the total budget of the account, or having some auto shutoff. You need detailed, real-time information from Amazon, which I’ve never seen in the console.

No one who is working on this cares about real-time by the second data - the daily cost is enough.

> Again, this is a strawman. This isn’t a response to anything I said.

OK, what are you trying to say? If my response above did not answer the question, can you give me a one sentence summary of the point?
ed basically works like what you can do in vim's normal mode (other than not having to prefix the commands with a :). IIRC, Bill Joy wrote ex as an improved version of ed and he subsequently added a visual mode to ex called vi. You can enter ex mode in vim using Q (though it may be bound to gQ) and you can exit it by typing vi.
That must be some Ubuntu-related issue, GNOME 3.26 on Wayland on NixOS is as snappy as it always was. Pretty much everything is instant.
in literature "exponentially" can be used in a lot of ways that are appropriate but not mathematically correct. you can use it as a euphemism, as a metaphor, as an adjective, like a loose comparator, etc... everything is valid.

the same applies to a lot of other mathematical concepts (i.e. the double negative, etc...)
FYI, the PDP-11 cost around USD $20,000 when introduced in the early 1970s. That's equivalent to ~$135,000 today.
It is a global effort, and not one limited to the US. Besides, the biggest improvements in ICE fuel economy and power are from Japan, not Europe. Europe hitched its wagon to the diesel engine, and we all know how that turned out.

Sure, turbochargers and hybrid tech aren't new in an of themselves, but that doesn't matter because there's still a lot of room for development left in them.

Even just 5 years ago, the idea of getting a roomy, nicely configured sedan that gets 55MPG city was a silly notion. Now, Honda sells them all day for $24k USD.
Take it as a synonym for "order of magnitude" and make your peace with the term? In scientific (aka exponential) representation, the exponent is actually higher in this case...
And + is overloaded in a bunch of ways students encounter in high school, and much time is spent talking about when you're allowed to add and when you're not and which rules apply when. Examples:

1 + 2 - fine.
1/2 + 1/2 - one set of rules.
1/2 + 1/3 - a subtly different set of rules.

1:20 + 0:45 - yet another set of rules. Modular.
30° + 350° - fine? But maybe modular.

15% + 20% - who knows? 15% of what? 20% of what?

(1,2) + (2,4) - can't be done.

a^2 + a^2 - fine.
a^2 + a^3 - nope.
a^2 + b^2 - nope.

It would be lovely if mathematics were taught as a strongly typed language without overloaded operators, alas all our corpus is in the language it's in.
If these are real, I'm sure all those startup founders are thankful for having their phone numbers published in public...
I think this one of those situations where you do a bunch of working out and get to the end and see that, mathematically, the problem is fixed, but in your heart it still feels like the original problem is still there. (1/2) * (1/3) + (1/2) * (2/3) might seem like a small calculation to us, but if you've just encountered fractions for the first time I think that is a huge amount of abstract notation.

Instead, I think it's better to follow CydeWeys's suggestion of saying that both are correct results of combining 1/3 with 1/3, but they're two different ways of combining them. Say that when you combine two fractions within the same group we call it "addition" and use a plus, but when we combine two fractions from different groups we call it "averaging" (and maybe make up your own symbol for it).

Once you've talking about averaging a bit you can move on to multiplication, which in some ways is a more basic concept but, for fractions, is actually a bit less intuitive.
Very true.

In my experience in New York, Verizon basically uses the public service commission as a level-1 helpdesk -- they take referrals incredibly seriously. I had an issue with Verizon equipment infested with bees -- and they literally rolled trucks within 30 minutes of getting a referral from the regulator, a pole and a bunch of equipment was replaced within 24 hours.

With TWC/Spectrum, unless they do something grossly incompetent or unsafe, the regulator is more like another party nagging them.

Interesting. I'd never purchased a Kindle book because I assumed I couldn't open it with any app of my choice(I use FBReader on Android)

But it'd be real nice to be able to purchase DRM free ebooks, a la GOG for games.
I would suggest to replace 1/2 with 3/6 since the number of students at each table is what matters, not the number of tables, which only yields the correct result if each table has the same number of students.
I prefer captchas or even arbitrary btc donations. Matrix.org Riot does this just fine. Since it is just for registration, it's easy for me to register in a privacy preserving conditon (vpn, private mode,noscript,etc...)
The units are missing, and I think that's a key factor here.

Both of the equations up on the board at the end are correct because they are counting different things. This is a huge miss if you use a numeric only approach to fractions.

The student came up and wrote 1/3 + 1/3 = 2/6.

What they meant by that is 1/3 (of the students at a table) + 1/3 (of the students at a different table) = 2/6 (of the students at those tables).

The teacher then demonstrates an entirely different formula:
1/3 (of the students at a table + 1/3 (of the students at a table) = 2/3 (of the students at a table).

The confusion comes because no one calls out that they're talking about fractions of different things.

Edit: There are a whole range of exploratory questions you can follow on from here as well.

Imagine if the tables have different numbers of students or if there are more than two tables. Helping students navigate these types of ratio transformations is why keeping track of units is so important. Otherwise, things can get hairy for the students very quickly.
Funny. I actually do the opposite.

Alternatively,

“The billing UI and billing infrastructure is a major weakness of AWS when it comes to helping people understand what their usage will cost.” You can clearly see this is true by the large number of people who complain about it.
Not very much when you are on the freeway.
Agreed.

I won't go back and edit my comment, but what you say is true. There really is an interesting thing going on here, even if the original paper was an over-reach.
Indeed, this was also one of my hypotheses. The problem is that there was much more asymptomatic transmission that it was initially assumed.

Even later, when the exponential got out of control, I expected the states to step in with much more drastic measures than the lockdowns we have witnessed. I thought there will be tanks on the streets, I thought one day we will wake up and see the military everywhere à la 1968 Prague.
I've done every step the author has done, in multiple flavors. I have the Kindle for PC app running under Wine on my Linux laptop, so that I can get ebooks I buy off Amazon decrypted and converted to EPUBs. I have the requisite suite of DeDRM tools and Calibre plugins so that I can strip the DRM off books I buy on my Kobo. At one time I had an Android VM so that I could pull the decryption key out of my Nook app and decrypt those books as well. It's a massive pain in the ass on every front, and I despise having to do it.

There is hope on this front, however. People need to understand this. The e-book manufacturers implement DRM at the behest of the publishers. Publishers can also request that the books they sell not be DRM-encumbered. You'll see that listed on the product page. See below:

https://www.kobo.com/us/en/ebook/lightspeed-magazine-issue-7...

> Download options: EPUB 2 (DRM-Free)

Or you may see a note like this on Amazon:

https://www.amazon.com/gp/product/B00ME0TBFE/ref=dbs_a_def_r...

> At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

It's not easy to find books that are DRM-free, but this does show that pressuring the publisher works. I think this is the route to go if we want to make DRM-free books the norm. Pressure the publisher, not the platform.
> Not i3 snappy

i3 isn't even snappy, the default application launcher can take up to 10 seconds to open on my old laptop.

There is a faster application launcher you can use instead, but you have to hunt through github issues to find out about it. The i3 project maintainers seem to actively object to telling users about 3rd party components and simultaneously refuse to integrate them or improve the default behaviour.

Problem is they are all built up of many smaller pieces as well - you may need the information about them at different points. For ex. EC2 drives are from EBS. if you need a load balancer ELB. You probably use S3 for some or other reason (log exports etc at least). You want a db - RDS makes it easier. Dynamo is literally a button click away. Kubernetes? Well there is EKS.

Yes you can probably launch your own cache fleet using a bunch of ec2 boxes - but you don't get all the low level hooks Elasticache gets. You don't get the pricing discounts either (I remember cross zone replication or something being distinctly free for ec2 but you pay for network. Same with dynamo - access from all zones cost the same pretty much IIRC).

If you are going to make the dive, it is worth spending the time. I would do a small overview bootcamp somewhere so that you know what's available and then start digging in for each new service you take up.
It's quite a famous quote from some notable smart person who I don't remember. I think they were talking about population growth (perhaps ironically). My intention was not to make a sly point about reactions to coronavirus.
You used too little context when arguing with an audience who isn't used to that style of writing...
Oh I never imagined it could be contained. It's not the 1950's where folks lived and died within 2 miles of the spot they were born.

People travel promiscuously today. Even if only 1 in 100 did, it'd defeat 'containment'. And far more travel than that.

Heck we are more careful with pets and cattle, than with people. Because, disease. People were somehow exempt because it's inconvenient to quarantine - takes time. And now we're reaping the result of this.
Really? The 1st paragraph is just about his friend trying to borrow the book, and noboby having it, and the author eventually buying it. Is the problem that people are trying to borrow books from their friends? This has been going on for centuries.
Without a system with prefixes every router needs to hold the next step for every single ip address in use in memory all the time and needs to be able to look them up fast.

I'm not here to criticize the content, just the to vent a frustration as a marketer:

Why does this industry keep repacking/renaming concepts just to sound like something new... it's like many get value out of perceived progress, when in reality it's just something that has been done for years.

This makes me want to step away from this discipline honestly. Instead of trying to compact knowledge to try to make actual leaps, it thrives on side steps.

Now here comes the new wave of Flywheel Marketers that are specialized in building Flywheels? God damn it...
> Also, try vim mode in VSCode before stating that it's not really mature enough and you're better off with vanilla vim. I am certain you haven't and are operating on the mistaken assumption that vim modes are not mature enough

I gave this a shot actually, and it was 1) slow and 2) missing features I used a lot. The tab/window/buffer behavior was close enough to feel similar but not close enough to be a direct replacement, and that just left me frustrated.

For anybody who has really deeply ingrained muscle memory on using vim (beyond the basics of navigating around a file), trying to switch to an IDE with a vim emulation mode is still a pretty big haul.

(This isn't to say that the vim-like modes of other editors aren't good/useful for people, it's just to say that for a lifelong vim user they may be lacking in too many ways to justify)
Internet 'marketing' is a fascinating pyramid scheme, where established players create content to help new entrants create content that will expose them to newer entrants. Somehow this should get everybody paid (not just the big players selling the domains and website creation tools).

A minuscule number of new entrants have achieved some form of success, so of course they get a louder and more influential voice.
I had a script to de-DRM books from VitalSource. It “printed” each page one at a time to a PDF and then concatenated the individual PDFs into a single file.

Sweden also has a larger immigrant population, many of whom have difficulty synthesizing Vitamin D. This factor should not be ignored.

> A risk factor that we want to highlight, however, is the low vitamin D levels found in the Swedish-Somali population. Vitamin D status is strongly related to low sun exposure and dark skin. In two different studies, the great majority of Swedish women of Somali origin had very low levels of S-25(OH)-D (< 25 nmol/l).[3,4] In Finland, Somali women required more than twice the amount of vitamin D in order to maintain recommended vitamin D status. [5] In addition, vitamin D deficiency was twice as common, regardless of gender, in immigrants from Africa compared with those from the Middle East.[6]
several battery breakthroughs that will dump the cost way bellow the holy grail of car batteries of $100/kwh that makes them on pair with ICE cars. Some estimates predict that they will go way bellow $80 in 2021-22, Means end of 2022 beginning of 2023 will be flooded with even cheaper comparing to Model 3 cars with better quality batteries. Good quality $25-30k electric car will be a new reality. Those segments attack bestsellers like Toyota Camry etc... I'm pretty sure the price war will push them even lower within 1-2 years. Means full line of EV's from very cheap to luxury by 2024-25 on a scale from multiple companies.
As a result we will have cars on the market that cost the same, perform better, and cheaper in a lifetime from service and fuel perspective.
Millennials and GenZ also very eco-friendly, which means younger people are eager to buy EV's.
The only delay could be new battery terra-factories rollout lag. That might give an extra 1-3 years lifetime for ICE.
After that the traditional car market will be shaking as never before.

>The fourth grader is saying "1/3 + 1/3 = 2/6" but the idea she's trying to get across is that "avg(1/3,1/3) = 1/3 but the size of the whole has doubled."

I disagree. The fourth-grader is perfectly correct within the context of the analogy that the teacher used. The problem is the analogy is wrong which is a general problem of relying on metaphors and analogies to explain rigorous technical concepts. Fractions are not like tables of girls and boys. There are rules for how you add fractions that flow from the underlying axioms. Those rules say that you cannot add fractions like "1/3 + 1/3 = 2/6", not because of any intuitive reason, but because it's disallowed by the 'rules' of fraction addition - that's it.
Half a loaf is greater than nothing. Nothing is greater than God. Therefore, half a loaf is greater than God.
Well, most arguments in the original article for DHCPv6 in android are based on things that either do not apply to android or are better solved without DHCPv6:

- DNS search paths can be set with RFC8106 RA options

- Changing DNS servers can be done the same way via RA options or via Anycast addresses

- tracking IP-host-assignments are better done with 802.1x, MAC filters and ARPwatch/NDwatch (One might use DHCP snooping, but that is usually broken with DHCPv6, also in this case, the security is in the snooping and blocking part, not the DHCP part). Everything else is really easy to fake and therefore useless.

- WLC options are only relevant in the control network of your WIFI which shouldn't really be shared with any android device

- VoIP phones should be a separate ESSID/VLAN/network because of QoS and security anyways. Also, most VoIP equipment doesn't properly handle IPv6 anyways, Let alone IPv6-only.

The only arguments left are: hostname registration and "everybody else is doing DHCPv6". Those are not bad arguments, but maybe don't justify the added support complexity for the android devs.
I think it's worth trying to be prescriptivist here. Exponentiality is a specific, important phenomenon, and it frustrates me to see language diluted in this way. I wouldn't care in the context of a reddit post, but NPR should know better.
If you thought it was inevitable as soon as a single case appeared in your country, that just seems misinformed. SARS was contained.
In the diesel case, fuel is immediately at its auto-ignition temperature when introduced. In this, the air-fuel mixture is heated until it reaches its auto-ignition temperature.
And today we can't do that? That's what I mean by, obsolete before it was deployed. IPV6 was designed in an age of lesser storage/higher cost memory and embedded processor power.

And no, not every one. Store the ones routed thru you. That's all you need. Look them up and keep a cache.
Frankly, the parent's point is more visible as the rare, generally dissenting discussion is almost always downvoted and show grey.
The blame issue is huge.

When humans are wrong, the business’ “ego” can be saved by blaming the employee who made the call, sometimes firing them. But the process goes on with the same error rate.

But when software makes the wrong call, it feels like the business itself has done the wrong thing. With no way to externalize the blame for the decision, the blame gets placed on the decision to use ml in the first place.

The narrative fallacy is that human form simpler narratives because the reality is very complicated to comprehend. May be it is true, but how to prove. It is possible to prove narrative is simple, but to measure the incomprehensible reality.
Agreed. Taking large amounts of admin workers from low productivity to moderate productivity (and RPA can easily boost the productivity of these kinds of tasks, if not the whole job by 200%) has a much bigger effect than hyperoptimising workflows that were already highly optimised.

I think it's important to know that this really isn't true. Maths at all times is a subjective language. Maths notation is imprecise "intentionally confused", or just ad-hoc defined all the time.

When you see something like.

f(x) = summation(x^n, n=0, 10)

We conveniently ignore that this polynomial is defined at x=0 despite 0^0 not making any sense by ad-hoc defining 0^0 = 1 in this context.

- also charges non-c USB

- does not explode (and bring down the whole trains outlets...)
