skysight-inc/HackerNews huggingface dataset:
Consider three conditions:

- high link-layer integrity; packet loss is mainly due to congestion

- low packet loss; most flows unaffected

- bursty packet loss; individual flows, where they see any loss at all, have a non-negligible probability of multiple back-to-back packets lost (e.g. in FIFO queue tail drop, or a dynamic routing transient like a black hole or brief (~ ttl) forwarding loop).

Consider the limit in which the number of simultaneous flows becomes large. In that limit, there is a lot of additional FEC data that has been generated, successfully transported across a network, and ultimately discarded as redundant. There is also FEC data that fails to help in the reconstruction of flows which experience a multi-packet loss too great for the erasure code being used.

We can calculate wasted power in this limit, and in some situations that waste can be significant.

One situation is when the FEC-generator is sending a large number of flows that stay near steady-state equilibrium amongst themselves and with other long-lived flows, which is reasonable to expect when multi-minute adaptive streaming video is the dominant component of the traffic.

Conversely a transmission that is sufficiently short that it never enters into the moral equivalent of congestion avoidance, and where the application is also latency-sensitive, small amounts of FEC in the early parts of conversations might be a win over retransmissions, depending on how often the FEC forms part of loss recovery.

In the modern Internet, the cost-benefit analysis of the extra power the extra FEC requires is probably strongly time-dependent, and it may be counter-intuitive. (e.g., if FEC doubles initial traffic, it may exacerbate any burstiness, which may in turn lead to greater burst synchronization; that is, in a microburst environment the additional FEC data, unless it's somehow congestion-avoiding (hard to do for very short flows) it might be the opposite of beneficial).

It's probably also worth considering differences in FEC receivers, for instance whether they are drawing power from a small battery or not. Consider a toy question like, "What drains more battery energy: two hours of receiving FEC or two and a bit hours of receiving non-FEC?" "A bit" may matter. It might also be dynamically calculable: lots of retransmits? Transition to sending FEC proactively. No FEC use? Transition to reactive packet loss recovery.

Anyway, it's cool to get even a little look at what Google's learned from its experiments. Everyone should encourage the sharing of these sorts of details, and we should probably encourage other large scale entities with different types of traffic (e.g. non-YouTube Google; Facebook; Twitter) to do likewise.
I'd suggest reading the Caro book.

The author literally spent decades studying the man and traced the arc of his life from his teenage years to political boss. It's pretty clear that the man was a racist, and personally drove publics works projects to keep races he disliked away from public parks, beaches and other things.

What we really need is a universal IoT OS. Something like Android for devices. Then we can enforce the same set of safety rules that apply for smartphones and have some relative ease of mind. Otherwise it's gonna be hell because on top of everything we'd have to deal with manufacturer's incompetence to build decent software.
In other professional disciplines particularly ones that require some sort of certification there are ethics tests and ethics committees. For example if your trying to get a CFA half of the test is ethics. Likewise for becoming and being a lawyer.

Given the importance of academia and its impact on policy in general perhaps something similar should exist?

I'm not sure if ethical tests and committees curb bad behavior but it could be a start or at least improve awareness. Maybe there is even something like the above already in place for academia that I'm unaware of?
Step 0: Do a cost/benefits analysis of your network connectivity, taking into account the risks of doing it wrong and the expense of doing it right, plus the support pain of doing it right but still having to deal with dodgy home network support calls, and figure out if it's even worth it.

Networked cameras do make sense to me, but a lot of the IoT stuff I see, if one really takes into account the full range of costs and benefits, are quite absurd propositions.

I feel the exact opposite on both counts. I've never really had a problem with Skype for desktop (though I agree that Hangouts is better), but the week after I updated my work machine to Lync was full of lag, dropped connections, and a suddenly bloated interface.
But that's not how much their house is worth to the market—it's how much their house is worth to them. “Make Me Move” doesn't reflect the cost of the property when you're ready to move, it reflects the value of the home to you when you're not really ready to move. It seems completely reasonable that that value would be significantly higher than the value of a piece of land that you need to or are looking to get out of anyway.

Same is true of a person who owns their own business but isn't ready to stop running it. You're not reflecting the market value of your business, you're reflecting the market plus emotional/‘satisfactional’ value of it.
Pro tip: It is often a good heuristic to identify a sexist by their use of 'male' and 'female' for humans instead of 'men' and 'women', because it sounds dehumanizing. Call them 'women', never females, etc, etc.
I don't think anyone was claiming what you seem to be arguing against; the point was merely that even the accidental and minimal security brought on by being unable to externally address internal networks is going away with IPv6. It was never "real" security, but it did make it materially harder to breach into someone's network.

Of course it's also going away with all the IoT things actively reaching out, since every external connection made without care is also an avenue for attack. ("Oh, you want your firmware update little camera? Have I got an unsigned blob for you! You're gonna love this update.")
Skype for business is the biggest dumpster fire of software that I've had to use for work in the last few years. Truly awful- resource hog, screen sharing rarely works, and frequently crashes.

Here in Brazil we have no such laws. You can drink anywhere and anytime. I remember drinking till 5am when I was a teenager and bars would stay open until the last customer was out. Today there is still no restriction, but mostly because of labour laws and the costs of maintaining service it's very hard to find open bars after 3am.

* edit: of course I'm talking about my experience living on a medium-sized city (Maceió). I guess bigger cities like São Paulo and Rio de Janeiro you can find a good number of late open venues.
I wonder if what we're seeing is a quantitative change leading to a qualitative change.

It's undeniable that old people have always held power in society, from hunting-gathering societies (various elders/shamans/wisepeople) through early civilization (Senator comes from the Latin "senex" for "old". Senatus = "chamber of old men"), though to today.

At the same time, their numbers (and effectiveness) were probably limited, either by a more pyramidal population distribution and/or by lower life expectancy (including duller minds in older age).

I think what we're seeing for the first time in history is a huge swath of healthy, long-lived older people, throwing the relative balance way off and leading to various situations we see across many different societies.

I like to sum it up as Boomers eating the young and I don't think things will change until the numbers/demographics do, ie, Millenials will experience a lost generation and things won't start to look good until we're well into middle-age.

The argument your link makes is that Singapore has low fertility therefore cities are bad, and I'm not being reductionist here that is literally all the content to be found there.

How do you uncouple the effect that the people moving into cities have on the city fertility rate from the effect the city has on the fertility rate of the people moving into it? Cities offer things that are valuable to people who don't want children (like, high utility activity for the time they aren't spending raising the children they don't have, compared to places that aren't cities) so they are especially attractive to people who don't want children, and you would expect any place that is attractive to people who don't have children to have a low fertility rate.
Well, even though I am not sure it would (because that OS would surely allow http requests, right?), there is no incentive for manufacturers to use such an OS, at least yet.

I can't really think of anything that would change this situation -- although IoT devices will get more sophisticated, they will likely remain quite single-purpose, with webapps or mobile apps serving as the UI, so there isn't going to be much to gain from a large common code base.
I guess they just don't want to be seen as competing with all the other wikis for specific franchises. Bulbapedia exists for Pokemon stuff, Mario Wiki for Mario stuff, Wookiepedia for Star Wars, Memory Alpha for Star Trek...

They want to be seen as a place for knowledge about a variety of topics, not one that's heavily focused on a single subject.

To be fair to mercurial, of which I have no experience, the point I'm really making here is that distributed version control has won. Seeing as you're arguing for SVN, you're in favour of non-distributed version control.

With regard to technology choices, there'll never be complete consensus. Many people still choose to write in C++ despite other languages having similar performance and features (Go, Rust, Java).

SVN may work for some people but by having the same power on the client as the server, I believe you fundamentally have a better tool. The functionality to work on, say, three independent changes on my development machine and jump between them is at the heart of git and for just that feature alone, I'd never go back to using SVN or Perforce.

Maybe some don't want to migrate to git but distributed version control is the paradigm the majority of the world is heading to, if they're not already there. We can agree to disagree because, in terms of tech choices, I assert that git has won comfortably and with good reason.

> What's the future for those Chinese Megacities? I'm not sure we see a linear/whatever development of them over the next decades.

Individual cities like Beijing and Shangai are peanuts compared to what is coming. I don't know if you are aware and if that is what you were referring to with "Chinese Megacities", but the Chinese government is working to tightly integrate larger regions. Some very explicitly directed from the central government, some thanks to city/province level cooperation.

E.g. the Bohai Economic Rim[1] include cities like Beijing and Tianjin. Currently about 66 million people in the whole area. There's work underway to tie them together with high speed rail, more highways, combining communications networks, government structure etc. Some projections suggest that all of the Bohai Rim will merge into a megacity with 250m+ people over the next few decades.

Then there's the Pearl River Delta [2], which includes Hong Kong, Guangzhou, Macau, Shenzhen, Dongguan and a number of other large cities, and which is headed in the same direction. Depending on how you count, the PRD is already the largest metropolitan area in the world with the number of people ranging from somewhere around 63million people and up to 120 million.

Then there's the Yangtze River Delta [3], which may compete with PRD for the largest population - the main contention is whether the YRD is one metropolitan areas or series of adjacent ones - it's not as tightly integrated as the PRD. Yet. But it has 140 million inhabitants, and includes cities like Shanghai, Nanjing, Hangzhou etc.

Chances are all three of these will in practice merge. Whether or not they will be unified to the point of being governed like cities is another matter (they are large enough that currently they straddle multiple provincial boundaries.

I don't think you understand my point because whether or not the man was clearly racist isn't relevant to it. The original quote was

> measured the overpasses on the Wantagh Parkway himself to verify that they were in fact deliberately built too low

I'm questioning how the measurement of the bridge allows it to be determined if the bridge is deliberately, or accidentally too low, in the absence of other information. You're suggesting that there is copious other evidence that the bridge was deliberately too low, but that kind of proves my point. The measurement didn't show that it was deliberate - other evidence did instead.

But this is becoming a bit of a ridiculous conversation for such a trivial point. I was just pointing out that it was sloppy writing.

Exactly, and they cast a disproportionately long shadow over society and politics.

EDIT: just look at the recent Irish referendum on same-sex marriage. A vast majority of the "no" votes came from the >60 cohort. I'll wager the age breakdown of last weeks election would reveal a similar dynamic: the young want change and meaningful progress while the old continue to vote for the past, keeping our culture and politics firmly rooted in the early/mid 20th century.
A lot of that is how we create friendships. Growing up in an area, you have many years with the same people. In college, you have many years with the same people. After you graduate, even if you're in the same area there will be multiple phases to friendship.

1. You're going to be working and single/married but still have plenty of time to spend after hours and on weekends with friends. The crux comes from income disparities that might prevent some friends from spending money on activities that others are willing to do.

2. As soon as kids happen, the group dynamics shift. The parents are often times going to be exhausted for a few years (especially if both are working), going out requires hiring a babysitter, inviting people over involves working around the kids or trying to avoid waking them. We host our friends all the time just because it's easier, but it's very different. Overtime this shift in dynamics becomes a big deal.

3. The solution for getting together with friends when you have small kids is other people with kids the same age who can play together. This causes another significant shift in the dynamic as you start to create new friends with parents from your neighborhood, school, church, scouts, etc. If you're in an new area and many people in these groups already know each other, then you're going to be responsible for making the effort to get to know them.

Partly because Wikia is a for-profit, extremely unethical company. They stuff more ads than content on their wikis, force established brands to move to .wikia subdomains, force awful design changes on their users, and they don't hesitate copying content from other wiki bases such as Gamepedia.

I thought about this a bit, and didn't answer. And today asked a colleague that had the exact same response as me.

There's no one day that stands out as a highlight that trumps all other days. That things went OK, nice and smooth, I got some satisfaction, perhaps some personal goal was reached or something got recognised, but there's no one day that I came home thinking I had the best job in the world. There are certainly days this doesn't happen, so to minimize these days is rewarding. A meaningful job, a satisfying job, these are all good days to go home to, but the best job in the world; I don't know what that is, and I think I'd be deceiving myself if I said I thought I had it, because every day brings new challenges and hopefully new cases for achieving a sense of feeling I had a worthwhile role and was contributing value to company, clients, and colleagues.
