In so assigning a dollar value, we risk boiling down a whole lot of qualities to a single number that doesn't necessary effectively capture what is going on.

I agree completely.

Obviously the evidence is compelling in cases where, for instance, the parents so destitute that they cannot afford proper nutrition for an infant during critical periods of neural development.

This article conflates things like that with kids who are stranded for a few hours at the bus depot because their mother couldn't leave work early to pick them up after taking the wrong bus home. That's ridiculous.
I had the same response, though not quite as witty. Don't know who this author is talking to but the folks I know who engage in this exercise-as-morality are quite firmly on the Left. The politicians opposing higher wages and subsidized health care did quite well among the smoking, cheeseburger-eating poor.

But Jacobin likes to pretend that anyone that even thought of voting for Hilary in the last election is basically a fascist sellout.
For the college question I think the bill and Melinda gates scholars (gmsp.org) is pretty compelling. They funded African American students who are now going into colleges. When you compare their scores / qualifications with their unfounded peers it suggests that kids who “know” they are going to college do better, and are more qualified for college than kids who did not think they would go. This appears to be true regardless of race or social class.
What's the key difference between Virtlet/KubeVirt and just running VMs alongside your Kubernetes pods? Is the main goal to centralize management? That seems reasonable, I'm just wondering.

Also, how does a Kubernetes-managed VM compare to a plain VM from, say, AWS EC2? I imagine it's a little less efficient, since the situation I'm imagining involves various VMs running a Kubernetes pod running the VM, but I may have this all wrong.

> genetic factors (that is distinct from heritability, which is lower, ~60%

You’re confusing something. Genetic factors = heritability, by definition[^1]. The 60% number is simply the heritability at birth (actually it’s probably lower), whereas the 80% number is the heritability in adults.

I see how this may sound confusing (how can heritability change?!). The reason is simply that “heritability of X” is, strictly speaking, a shortcut for “heritability in the variability of X”. As children grow up, they are influenced by their environment, which accounts for part of their intellectual development. As adults, they are still influenced by their environment but since the majority of their intellectual development has already taken place, there’s less room for variation here.

In other words, between two toddlers there’s a lot room for variation in upbringing with influence on their IQ. But if you take two University graduates from the same school, with doctoral degrees in particle physics, they will have relatively little variability in their IQ that’s due to their upbringing. Instead, the difference in their respective IQs will be mostly due to genetics (80% of it).

> but [the effect of intervention] fades into adulthood and eventual life outcomes

No, that’s another misinterpretation. The effect does not fade, it’s sustained. It simply seems to fade since you are comparing a different population/peer group (see my example of the two PhDs above).

---

[^1] I’m aware that there are other vague definitions of heritability and genetic factors flying around, just to confuse things. However, these aren’t rigorously defined. In genetics, heritability = genetic factors.
I recently set up a couple of Mastodon instances - one for an interest group, and one for my family. The latter is effectively dead, but the former is slowly gaining users.

The biggest problem I've found is content discover. Mastodon works well for new users if the instance you're on has others who follow users that interest you - otherwise, silence. There is no way that I've found to search the entire multiverse, and no easy way to bootstrap an instance by connecting to other instances or other instances' users en masse.

Very low inflation nominally, according to a measure that does not factor in 1. Rent 2. Medical Expenses and Health Insurance 3. Education, stuff that matters more than the eggs and milk the CPI measures
The flipside is that in Erlang often need repetitive code like so:

case X of
{expense, N} -> Total - N;
{invoice, N} -> Total - N;
{loss, N} -> Total - N;
{credit, N} -> Total + N
end

whereas in ocaml (and F#, modulo details) you could just do something like:

match x with
| (`expense, n) | (`invoice, n) | (`loss, n) -> total - n
| (`credit, n) -> total + n;;

The examples are unidiomatic and artificial and you can sometimes ameliorate it with guards, but it's a frequent (minor) annoyance.

Pretty much. See in English railway (Eisenbahn in German) or runway (Startbahn/Landebahn) for the equivalent patterns. Especially since in the beginning railway and Eisenbahn meant primarily the way with rails only, not the entire enterprise.

Autobahn might actually be derived from Eisenbahn in that Wikipedia says some group choose it because of the similarity, but it only works because Bahn is the more general concept.
It is really sad that this design wasn't built. The Concorde was a great design, but obviously, you don't hit perfection on the first attempt. The Concorde "B" shows, that as with any design, it is important to have enough iterations to get real efficiency.
The Shuttle was a great design for the late 70ies. If it had at least a significant design iteration every 5-10 years, it could have been a bigger success. Similarly if the Concorde hat gotten 2-3 design iterations over its life, it could have been very successfull.

I think the jump from having children to having a toy robot is still a bit too far. In a few decades maybe, if and when AI has come to fruition (that is, real AI, not the machine-learning fad which is so much en vogue at the moment). Until then I think these toy robots are just that, toys. They might be fun, just like other toys. People might get attached to them, just like they can to other toys.

You should inform the maintainers of CentOS, to take one example.

CentOS 6.9 (supported until November 2020) runs 5.3 with backported security and maintenance updates. Newer versions are not available from them for 6.9.

The issue is not that upgrading cannot or should not be done outside of their repos, but that many, many developers and site admins for various strong reasons are not in a position to do so. There may be other dependencies on either CentOS 6.9 or earlier-than-latest PHPs, or they may not have the freedom to switch distros or PHPs for any number of reasons.

Please consider the possibility that you do not understand the real world in which many, many developers work.

> Do you have a link to this paper on arXiv?

This part was sarcasm.
The distortion sounds like it is applied to individual strings, if it were applied after summing, it would not only resemble more a real electric guitar, but also sum- and difference frequencies of detuned strings would be audible much nicer as beating.

Furthermore, the intervals E-A/A-D/D-G and B-E are not exactly perfect fourths, they should be equal tempered. Luckily the difference is almost negligible for the fourth, the perfect interval would be 4/3 = 1.3333 versus 2^(5/12) = 1.3348 for equal temperament. The interval G-B however is a major third, here the perfect interval is 5/4 = 1.25 while equal tempered is 2^(4/12) = 1.26 Those minor errors accumulate if one string is tuned based on the preceding one, the interval from lowest to highest strings can be calculated:

(4/3)^4 * 5/4 = 3.95 for perfect intervals,
2^(4 * 5/12) * 2^(4/12) = 4 for equal temperament.

The highest string should be exactly two octaves (= a factor of 4) above the lowest one, so the equal temperament should be preferred. A practical result is that tuning a guitar using only intervals of adjacent strings will never really converge to the ideal result, so tuning (fretted) octaves and flageolets should be used in addition.

NanaGram is a super simple service for sending regular printed photos in the mail to your loved ones. Our service acts like a Netflix account. After you sign up, we give you a unique phone number and you can share it with unlimited family and friends. Once someone is approved by you they can send in photos and together the group curates a few fresh photos per month. We print and ship 4x4 and 4x6 prints in glossy or matte. All you have to do is text your photos and wait for a phone call from your loved one.

We’ve had a nice bump in growth the past couple weeks, with Mother’s Day on the horizon (Happy Mother’s Day, Mom! <3) and lots of new folks planning to use us as a gift.

This is the happiest product I’ve worked on. It’s super heartwarming to see it bringing families closer together (the product functions like a private family social network), bringing our elders into the loop (many of whom don’t do social media), and most of all the increase in phone calls and visits.

to be charitable to the author, it's not so much that the ideals aren't good ones, it's more the preening self-regard that the upper middle class (author's words here, and it's an important distinction) holds while engaging in this lifestyle. Not to mention the judgmentalism that they cast while doing so.

Where the argument breaks down is that he connects this with some sort of oppress-the-poor policy program, when in fact the crowd that most loudly crows about its yoga practice and organic food consumption is squarely behind the policy program of living wage and universal healthcare.

>Fines can increase without hiring more people or buying more cars

Fair point.

>Why would they need to make a net profit?

At the end of the day the resources either come from somewhere else or it costs more taxpayer money. Yes, I agree it would improve safety.

>The argument that it costs too much to increase enforcement in any way doesn't really hold much water.

It does though because it is the only solution and the fact that is costs too much is the main reason it isn't done already.

>So how would you make roads safer?

That isn't my job and it isn't a pressing political issue in most places. If autonomous cars exacerbate the problem, they should lobby the state and local government to spend more on traffic enforcement to enable them to operate safely.
While the central point about using things inherent to your structural position in life as a personal morality skewer is spot on, I find some of the buttressing arguments annoying.

> if upgrading to PHP 7 is going to break the shitty old version, that's a problem too

The problem is that PHP 7 finally removed some legacy APIs that had already been deprecated for an eternity. The removal wasn't a bad decision in and of itself, but there's a non-trivial amount of code in the wild that still uses those ancient APIs, either because it was written more than a decade ago before they were deprecated, or because it was written by people who either didn't understand what "deprecated" means or didn't care. So when that code moves from 5 to 7, it breaks.

WordPress core is developed by smart people who stay on top of changes in the language they work in, so moving to 7 wasn't a problem for WP itself. It was a problem for lots of WP themes and plugins, however, since there's lots of those that were written and then abandoned before 7 was a thing, and even some that were written by people who knew 7 was coming and just didn't understand why they should care.

If I were going to suggest one thing WordPress itself could do/have done to make the transition less rocky, it would be to require PHP 7 compatibility for plugins and themes distributed through the official repositories at wordpress.org. Currently that's not a requirement -- there's not even a way to filter out PHP 7 compatible plugins and themes from the ones that are stuck on 5. So unsophisticated users are still getting recommended software by those repositories that will break if you run it in a modern PHP environment.

(You can avoid this problem somewhat by looking for other heuristics that correlate well with PHP 7 compatibility -- actively updated plugins will tend to be compatible, well-reviewed plugins will tend to be compatible, etc. But you can't just ask directly for plugins that will work with PHP 7, which is a shame.)
This is brilliant and I love that it relies almost entirely on Linux primitives already in place.
You are absolutely correct. But there is an upshot to this -- modular infotaiment system that you can upgrade every few years.

Are you referring to "velocity of money"? Yes, it's a thing and economists agree it's a thing. But it does not follow that UBI causes runaway inflation - as we covered above. And there is certainly no
consensus among economists about runaway inflation from UBI. (Unless you care to provide references..? I just did a search and came up emty)

Do you think that UBI is qualitatively different from normal tax financed income transfers, from inflation POV, or do you think that just bigger income transfers cause runaway inflation?
Your attitude on this entire thread has been incredibly condescending. Why don't you try and think of why these problems are hard instead of just assuming they are all easy, as you've done so far?

I challenge you try and think through why your simple spam filter and human appeals process will not scale to Twitter's size. What kind of throughput can it handle? What happens when there is more content being appealed than the review team can handle? How do you prevent attackers from maliciously flagging other users' content? How do you handle advanced threats where attackers compromise existing accounts then begin to spam, thus bypassing any "easy" checks like looking at account age? How do you classify "hateful" speech? How does it scale to foreign languages, slang, etc?
Because you already do?

While the central observation of the article is vaguely interesting, what is more interesting perhaps is the slow and gradual pivots from Victorian moral signaling to modern moral signaling, and whether modern moral signaling is more or less adaptive towards actually making one's life better than Victorian moral signaling was.

For example, life satisfaction is strongly correlated with exercise. This was true even before the general population used exercise to signal virtue. (See the Harvard longitudinal study as an example of this.)

Additionally, the modern practice of allowing (some) women to have highly successful careers seems to lead to better outcomes than the Victorian practice of locking women out of everything except teaching and nursing, and encouraging them to get out of those as soon as they could lock down a man.

Perhaps virtue signaling slowly converges on actual virtue? (This isn't to imply that all modern virtue signaling practices are virtuous. For example, I'd argue that modern virtue signaling around sleep, or lack thereof, and work, namely filling one's life entirely full of it with no breaks, at least in the USA, are terrible for health and life satisfaction.)

Edit: added clarification that modern values around female careers are better than Victorian ones, but are not yet a fully solved problem.
