Many utilities are run on a cost plus basis which means they would be entirely economically rational to literally turn down free money, because it would reduce the amount of profit they could make.

Also, the duck curve doesn't show peak use. The duck curve shows the peaks that are left after solar has been subtracted.

Go find a duck curve, note that it will almost certainly be in springtime when overall demand is low. Then look up the yearly demand peak for that region. It will almost certainly be in the afternoon in the summer and will dwarf the duck curve peaks. So solar will be directly reducing the requirement to build out capacity (and further reducing utility profit potential/ saving everyone lots of money).

Worst case scenario for the duck is to throw away a bit of solar power sometimes because other parts of the system need time to ramp. People clutch their pearls at this, just like they do at negative prices, but it's just nonsense with no logical basis.

It's like complaining that buying a dozen eggs is wasteful if you only need 11. Yeah, but it's cheaper than buying 11 individual eggs so maybe just think of something to do with your "free" egg instead of complaining about a non-issue.
100Mbps was fast 15 years ago. These days it's the bare minimum. And remember that you'll be sharing this capacity with all your neighbors who sign up, and since it's wireless you can't just expand the capacity by adding more cables.

And, as jkilpatr mentioned[0], the latency will make it pretty much useless for a lot of applications (such as real-time multiplayer games, or anything that creates a lot of short-lived TCP connections such as web browsing).

The only way to build out decent Internet infrastructure is to dig. Even if they come from the best intentions then these WISP efforts ultimately just end up poisoning the well.

Then again, maybe it'd be a good thing to keep connectivity at a point just before garbage like Stadia becomes viable.

Shout out to the lonely node on Smith and Douglass! Howdy neighbor.
I really want to cheer for matrix/riot and this blog post moves me in that direction, but then seeing your comment as lead-dev throws me back into reality. The post is all about _tightening_ privacy! So why is the suggestion to solve addressbook feature more elegantly than a a TOS not addressed and instead GP is dismissed as being hyperfocused on privacy.

The reason I cheer about Matrix is exactly because of its P2P nature, which neither of the other privacy focused solutions like Wire/Signal address (though these give better privacy right now). Isn't it exactly the privacy conscious crowd that matrix is pitching to? Those of us who don't trust a signal or wire server because that server code is proprietary? Matrix has been promising better privacy (and e2e encryption) for some time but maybe this isn't actually where matrix is heading? I sure would like to know because there is no point for many of us to continue cheering for what otherwise looks really promising. And it's not like a better technical solution for the address book doesn't exist!!

The Day of Two Noons
I find these articles interesting if looked at from a historical standpoint. Imagine an article from 1939 decrying the treatment of German scientists in the US who happen to be sharing information with the Nazi government back home. In the modern version of this, we have an apologist admin on HN changing the article title so no one flinches at its original obvious anti-US slant, there’s no mention of China’s horrrible human rights abuses like concentration camps and organ harvesting, and now there’s discussion rules making sure there’s no US “nationalists” commenting against China. I wonder if people who hated the Nazis in 1939 felt the way I do right now about the pro-China people.
I have gigabit fiber at home. I also run a WISP.

This is from one of my wisp customers taken literally seconds ago.

root@OpenWrt:~# ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1): 56 data bytes
64 bytes from 1.1.1.1: seq=0 ttl=61 time=7.791 ms
64 bytes from 1.1.1.1: seq=1 ttl=61 time=7.084 ms
64 bytes from 1.1.1.1: seq=2 ttl=61 time=6.691 ms

Same server from my gigabit fiber to the apartment unit

[justin@DESKTOP-UALBV95 ~]$ ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
64 bytes from 1.1.1.1: icmp_seq=1 ttl=56 time=11.4 ms
64 bytes from 1.1.1.1: icmp_seq=2 ttl=56 time=11.2 ms

The point to point customer antenna added ~6ms of latency the remaining ~2ms is the fiber line to the internet exchange.

tl;dr Wireless point to point is easily competitive to Cable on speed and anything on latency.
As a long-time follower of digital currencies, while I have some skepticism about Libra (and see plenty of opportunities for competition), it's hard to take an editorial like this seriously when it's making such terrible arguments.

The piece starts by claiming that Facebook is profiting from Libra by collecting one-time fees from participants, and that this would somehow be motivation to launch the endeavor. This is so wholly wrong that my head spins a bit at this - the Libra Association members pay in $10M (which gives them a single vote, and "Libra Investment Tokens"), and the cash goes to support 1:1 backing into the Libra Reserve - while there may be a float, the return is basically de minimas since it's basically going into short term treasuries and the like. Considering these funds are controlled by the association (a Geneva non-profit) and that all members have equal voting right, I don't see how there's any way that Facebook Inc (or any individual member) could actually make a "cool billion dollars" in any way from this. Either this argument was made from not taking a few minutes to make a cursory read any of the website announcements or white papers, or is, I don't know, pure imagination?

The second argument is less bewildering, but shows even less understanding of what kind of play Libra is. It imagines that somehow FB will benefit (as a 1/100th investor in the LA) from transaction fees! If the goal were to maximize tx fees from a payment system within FB properties, they'd have been much better off launching a first party payment system (the same is true if the only goal was for collection of transaction data, btw). Sure FB wants to make money from Libra, but it'll be by creating exactly what it says on a tin - an open access, low friction, cross-border, transactional digital currency. FB benefits from opening up huge markets in (especially) its EM marketplace, which has been largely underserved by er everyone, and by creating new markets (microtransactions, small international transfers) that have been simply impossible without a true "internet" currency.

Of course there won't be any privacy, but this IMO is driven as much by KYC/AML/global money flow of sovereign interests, as much as for consumer data mining purposes. We know how to make private cryptocurrencies, but it'd simply be DOA if that were what were proposed to any regulatory authority around the world.

IMO FB has pushed the conversation forward in a good way and I'd say that it's up to everyone else (whether its competing national or corporate consortiums, or open-source/independent cryptocurrency projects) to step up and offer some better alternative.

For those arguing that this should simply be stopped (or for the status quo of how money and banking currently work globally, which I personally think is much worse than what Libra promises), well, I guess at the very least, argue better.
Like everyone else they want to become the next WhatsApp - with only "the privacy conscious crowd" they don't think they'll get there. They market to your mom.

I don't think your comment helps. An alternative to Slack exists: Zulip and Mattermost and both aren't annoying to use. You can use Signal instead of WhatsApp or if you don't trust that you can also use Ricochet. Being passionate about something doesn't make them a Nazi.

> it's easiest to get them involved cause these people all know each other, obviously.

Right and that's precisely the reason drug cartels are so attractive to the people who run them....what's your point?

> Visa, Mastercard, Paypal, Stripe, etc.

Are you serious? If you don't understand how in bed these companies are with each other then I have a bridge to sell you.

You've brought up some seriously good points about how Libra is a reaction to WeChat, but IMHO this is a naive perspective into historically how companies work with each other in markets.
Keep in mind that by buying DRMed books you give companies an incentive to produce them. If you're opposed to DRM, it may be better to pirate instead. Especially if you live in a jurisdiction in which removing DRM is illegal so you're breaking the law anyway.
Because it doesn't make much sense to me. Those truly decentralized currencies are choking out themselves with slow transaction speeds and high transaction fees all on their own.

I think true decentralization is super interesting and I'd like to see it happen (I think, there's some unease for me still relative to fiat). I think Ethereum 2.0 with it's proof-of-stake and sharding to combat transaction speeds is super interesting, for example.

Libra is an in-between that could bridge today to tomorrow for true decentralization.

Parallelize GCC with Threads – First Evaluation
Okay, so i guess it's not really a question of privacy hyperfocus but just different users having very disjoint use cases.

I'm not sure i'd characterise this as phoning it in: the point of the blog post and all the accompanying bugs is to spell out that we're trying to solve for once and for all the problem of how best to enable contact discovery for folks who want it (as opt-in rather than opt-out!)... while also keeping the private-messaging crew happy. Totally agreed that it's been half-baked historically though, which is why we're fixing it now that 1.0 is out the door and we have some bandwidth to address it.

> Separate the flows.

The idea here is absolutely to separate the flows. We don't have a final UI proposal yet (as is clear from the bugs) because we're still working it through. The closest is probably https://github.com/vector-im/riot-web/issues/10091 right now.
Studies have shown that current UI is much, much less responsive than 1980’s teletypes.

I’m not sure if those were peak UI performance. It wouldn’t surprise me.

I’m guessing at least a generation of people haven’t actually experienced reasonably responsive computing environments.
Ever watch two kittens get themselves all tangled up while playing with a ball of yarn? Imagine being one of those kittens and getting tangled in string in front of an audience of other CS PhD students and senior CS researchers. In addition to the issue that we really couldn't simulate what GC was doing (or even explain it), imagine trying to untangle yourself while doing it.

To answer the question about why GCs are an issue, a GC scans memory, moving objects, updating pointers, writing marks in special headers, etc.
In a perfect world there would be no DRM in the first place.
Why would you continue to pay for something that you weren't using though? That seems odd to me in terms of being responsible with company money, especially if it came down to some free tshirts.

Dunno about Zulip, but IMO Mattermost is pretty clunky and uncomfortable.
In short, no. There's a reason that General Number Sieve is only used for numbers bigger that 10^80 and Elliptic Curve Method (ECM) is used instead. If number is smaller, than you don't benefit from the better complexity. This invalidates your point, because it might happen that your hardware is fast enough to factor a number using ECM and not fast enough to do the same with GNFS. So practically speaking, you don't have any assurance that what you have is fast or slow. Of course, it might happen that you actually manage to factor some big numbers, in that case you have the empirical proof you sought.

> Why would a non-profit or NGO or university (several are already in the Libra Association) stay silent?

Because they don't have equal say perhaps? Or more realistically, because staying silent would politically benefit their institutions.
Totally agree. Using non-Latin characters would be a non- starter for most of the world.

It's simple: Zuck wants to do basic stuff on FB like have an easy link that lets people split a bar bill or have an easy link for buying into a bridal registry, and his lawyers keep telling him stuff like "don't do that or FB will be regulated as a bank" or "don't do that or FB will need to do KYC" and he's sick of hearing that.

Libra's sole purpose is to let FB do this kind of stuff while sidestepping the regulatory red tape.
In most cases, most certainly not. If the OP was hired as a managing PM with direct PM reports, that's a different story. It is unclear what the context is.
There is a non-dark side to DRM? Seriously, it just makes everything worse out of a misguided sense of greed and scarcity while not stopping piracy.

The whole concept of DRM is certifiable. Asking to have something accessible yet not accessible to the end client at the exact same time.

When it can be bypassed by capturing the output channel anyway on top of that.

It does come from a single point but they can not tell where inside the shaded area of space the single point was.

As far as I can tell from their website the event was seen by Virgo and only one of the Ligo detectors (Livingston), which makes localization in the sky rather uncertain. No clue at the moment why the second Ligo detector (Hanford) did not see it.
I run cable with WISP as fallback, their ping times in pfSense gateway monitoring for 1.1.1.1 are within ~5ms of each other.

Point to point can be faster than cable due to fiber/copper running at a fraction of the speed of light. That's why some HFT firms prefer ptp links.
Well, correctness / security are probably more important than performance.

(Spoiler alert: If your system is well-enough implemented to be correct, it is well on the way to being secure and performant too)
This, basically. People should stop thinking about "composition vs. inheritance" and start thinking of implementation-inheritance and thus OOP in a strict sense as "composition plus open recursion". Open recursion (viz. the fact that methods defined on your "base" classes can invoke 'virtual' methods on self and end up depending on behavior that may have been overridden at any level in the class hierarchy) is quite often a misfeature and not what you actually want, given that the invariants involved in making its use meaningful or sane are extremely hard to usefully characterize.
Not sure why this is here, but a universe where this exists is more interesting than one where it doesn't.

I’ve been lucky to get 2Mbps at places I lived in the last couple years. 100 would be lucky for me.
No way, 100Mbps is fast today for most people.

This 8K youtube video is 5m38s long and 850MiB large: https://www.youtube.com/watch?v=1La4QzGeaaQ

100Mbps down is fast for most people. What do you think the average user is doing that needs more than 100Mbps down?
Naively, it would inflate the absolute values, but you might be able to correct for it in various ways. Still, knowing that tank production fell 50% is probably useful, even if you don't know what exactly it fell from....

I would get up, go to the managers, if they don't listen to me I would go to the CTO/CEO then explain why that's a huge mistake that may cost peoples lives. If they don't listen to me I would go anonymously to the police and explain the situation. If nothing is solved I would start writing heaps of posts about this and fuck what the companies would think about hiring me.

The thing that made autogyros (and helicopter autorotations) click in my mind was when someone pointed out that the outside of the rotors is spinning faster than the inside. As such, there's a balance where some point inward of the rotor tips will be driven by air flowing through causing the outside to spin fast enough to generate positive lift. There's obviously more to it, but if anyone is wondering why air going up through a rotor somehow causes that rotor to push air back down, this might be a helpful way to think of it.
