> (abstract) Optimizations for throughput are: MTU, packet sizes, tuning Linux kernel parameters, thread affinity, core locality and efficient timers.

Cloudflare's u/majke shared a series of articles on a similar topic [0][1][2] (with focus on achieving line-rate with higher packets-per-second and lower latency instead of throughput) that I found super helpful especially since they are so very thorough [3].

Speaking of throughput, u/drewg123 wrote an article on how Netflix does 100gbps with FreeBSD's network stack [4] and here's BBC on how they do so by bypassing Linux's network stack [5].

It's not. The site detects cheating and is pretty good at it.
He’s pretty much right though. It spreads worse than the flu and Dr. Ioaniddis recently published a serological study showing it seems to have a mortality rate similar to the flu. An overwhelming majority of people who get it will not die. Ioaniddis et. al. suggests the evidence points towards 1~2 out of a thousand mortality rate.

We should not be panicking. We should be mitigating the disease based on the evidence at hand.
I think Wolfram makes the point himself that the model may not directly be predictive in the way that states "encrypt" their predecessors. I guess the best bet is to show that there is a direct connection between his model and higher models, because then you can start to look for physical manifestations of things his lower-level model predicts that don't exist in higher-level models. Kind of like how GR keeps getting reinforced by verifying its predictions with phenomena that hadn't been considered before its advent.

No Nvidia drivers is very frustrating. I built a Hackintosh in mid 2017 with a GTX 1080 and it was a dream. Accidentally killed my build and didn't have time to figure out how to fix it, so I was using my hardware as an Ubuntu server for a lot of data processing and machine learning. Finally turned it back into a Hackintosh again this week and was so bummed to find out Mojave and Catalina don't have Nvidia drivers.

Granted, it's still way better than the mid-2012 MBA I was using, but I wish I could still use that GPU.
It's such a sad situation. Why can't companies just provide all the necessary hardware info in the datasheet?
Re-Idea: Agree, sounds useful.

Validation: I would suggest first time someone clicks a headline after the feature is live — that by default before opening a new window the user gets an alert allowing them to configure the setting and confirmation they understand how to edit it later if needed.
Apple is a pile of cash that has a few developers on hire. Most of the developers who made the Mac really great left Apple years ago, and the Mac's been a third-class citizen at Apple for over half a decade. Some guy deciding not to pay for Mac OS, for whatever reason, isn't going to break the bank at Apple.

Apple could make nothing from the Mac and it'd still be more than worth it for them to continue maintaining it because of the benefits it brings to their mobile ecosystem.
It seems to go either way, depending on the source, the consideration of “proto-writing,” and interpretation of date ranges:

That's elegant.
I'm curious about any feature differences between this XDP code and the normal routing code path. Where are the cycles going? Given that they're both using the same drivers and the same FIB lookup, I wonder if there's a way to increase normal routing performance closer to XDP.
Controversial ‘gene drive’ could disarm deadly wheat pathogen
60% to 70% refers to an R0 of about 3. But the R0 is more likely to be around 6. That means you need 5/6th of a population to be immune - that's about 80% to 90%.

UPDATE:

"Results show that the doubling time early in the epidemic in Wuhan was 2.3–3.3 days. Assuming a serial interval of 6–9 days, we calculated a median R0 value of 5.7"

https://wwwnc.cdc.gov/eid/article/26/7/20-0282_article

A herd immunity strategy involving fast immunization by continuing business as usual would then involve an R0 > 5.
I look at these reports as checkpoints of trends that are already happening. All you need is a keen observational eye and some data to back up the qualitative observations to produce something like this.

I don't view these reports are being in the business of predicting the future.

They are describing what's already obviously happening with maybe an optimistic eye towards the future.
Pick a better college than this one then. There are plenty.
Yes, I know that much.

Imagine a sine wave, except when you look at it at 1000x magnification it's a sin + cos. It looks smooth, and at x = π you think that the derivative will be -1 but in fact it's 0 because you don't have a sine crossover there you have a cosine trough.

Except at 1000000 times magnification (ie another 1000) the cosine curve that forms that apparent sine curve is itself a sine curve. So everything is switched again.

f(x) is something like sin(x)+cos(ax)/a+sin(a^2x)/a^2+cos(a^3x)/a^3+ ... (sin(x.a^j)/a^j+cos(x.a^j+1)/a^j+1+ ...

for a=some arbitrary large number. Something like that, I'm a bit rusty, sorry.

At whatever scale you look at the curve the derivative is always wrong: you zoom in on the sine, at the peak it's got a cosine, so the d/dx is -1; but zoom in and the cosine has a sine at the crossing point, so the d/dx is 0; but zoom in and ...

The curve is provably smooth, it's sinuses all the way down, but nowhere can you tell the derivative as it's fractal???

That's what I had in mind.

Anyway, I thought their might be clever curves of that type.
This looks promising, thanks!

That makes more sense. And we could still break out states into functions without being quite so explicit as in the article (and without the __init__ problem I described):

def create_state_machine(self):
if yield == 'a':
yield from self.q2()

def q2(self):
while (char := yield) == 'b':
pass

if char == 'c':
self.match = True

Or something like that anyway, untested of course.

(NB that actually fixes a bug in yours in that it would continue processing 'b's after the 'c' - of course that's still a match for the regex, but the FSM should have stopped.)
True. I think it's important to remember that it's ultimately not your obligation or responsibility to help others, it is a gift. I've found this mental distinction allowed me to create healthy boundaries around my time and resources. It's important to be able to draw the line at how much you're willing to give without feeling guilty.
I don't understand. If they wanted to tax it for the government / social programs it would sort of make sense. But why distribute it to old media companies?

Is there any merit to this at all?
What if Google and Facebook just said “No, thank you.”? I think Google and Facebook have more power in this relationship, which might say something about the tech giants. The only possible thing the Aussies could do is block the websites, and that sounds like political suicide to me. I’m guessing the companies will decide to play ball, but if other countries start to follow suit, it might be interesting to see what happens if they start pushing back.
> the length of that interval is bound by the ratio of the error in the data over the derivative with respect the parameter

This is interesting! Could you expand on this a bit? Why is the length of the interval bound by the ratio of the data error over the derivative?
When you’re choosing Scala you have all the perks of JVM platform. You can reuse Java libraries if needed. Scala has pretty powerful type system. JVM in turn is a pretty good platform, with decades of effort, which can tolerate high load, make different optimizations in runtime, tolerate large heaps if needed, GC story in Haskell runtime is not even close to JVM.
I don't know if that's true, because I think the idea of a rule having causal invariance is that the many paths converge anyway into causal sequences of events that always hold.
Traditional error free transmission in optical comms is 1E-15 BER. I can't access the EPON standard right now, but my experience with other IEEE standards would tell me they're probably guaranteeing 1E-15 for worst-case optical link. This link is pretty close to optimal, so 400G of data is nowhere the amount to say anything with certainty about the BER of the channel.
No. All modern DNSSEC implementations are online signers anyways, because the BCP mitigation for zone enumeration, "whitelies", depends on that. So what we in fact have is the worst of both worlds: a protocol that makes painful compromises to work in an offline-signer model, and all the operational concerns of online signers. A DNSSEC that was designed for online signers from the jump would be cleaner and more secure.

That the root zone was signed with 1024-bit RSA in 2016 is its own dunk, and I think you for making it for me, but of course the root zone isn't the only zone; the 1024-bit root just meant every TLD was capped at that level of security. Now they're not, but the rest of the DNS is still littered with them. See: every DNSSEC survey.

And, of course, you've addressed only a small part of that previous argument --- just the key sizes.

I don't know what point you're trying to make about BGP. I think you think I'm opposed to RPKI. I'm not.
If lots of smart people decide to not start then it might be easier to get in for the Fall semester if you're less able. That is, it might be to your advantage to start college this Fall.
The code was to require the companies to negotiate in good faith on how to pay news media for use of their content, advise news media in advance of algorithm changes that would affect content rankings, favour original source news content in search page results, and share data with media companies.

This seems...confused. At that point why wouldn't Facebook, Google, et al just ban the media company links from their platforms and avoid the hassle?

An alternate approach is to have kids young while you work through the grind-ier stages of your career and then do your high impact work when they're teenagers / young adults. One benefit of this approach is that even if your attention is sometimes away from them during that stage in their life they still get to see what you're doing, and if you take time when you can to talk to them about it they'll feel at least a little bit involved. In my experience sometimes bringing what you're learning as a parent out in the real world back home to them can be very engaging for them. School can be very mundane, and a glimpse in to how the real world works can be very enlightening.

When I first became a parent I thought it would be great if I could just stay home with my kids all the time and not have to go to work. I thought that would be better for them and me, and concluded that's what I'd do if I ever had fuck-you money. Then when they got old enough to have conversations with (3-4 yo) I realized that they really engaged with conversations about things outside their daily lives, which for better or worse can be very routine. If I wasn't going to work I wouldn't have much to tell them that they don't already know. And again for better or worse, young kids and teens tend to see anything that happened before they were born as ancient irrelevant history, so I'm not sure that telling stories about the glory days of past contributions would have the same impact.

Lastly, if you'll pardon a bit of good-natured snark, while

> Empirically, people with kids almost never achieve outlier levels of success

is certainly true,

> Empirically, people almost never achieve outlier levels of success

Is almost equally true!
When I was a kid, all I did was give. I gave until I had nothing left to give. When my mother found out about it, she would always yell at me and ask, "what about you? How are you going to survive without X?"
Truth is, I never thought about the consequences. I just knew that if I gave someone something they needed, that was all that mattered. And it felt good.
I'm 29 now and my mother is late. Things are different. I am the most selfish person I know. I always give less than I want to give. Sometimes, I just outright say NO. But that's because I am trying to build a life for myself. I am saving for marriage, a house and my business; so I hardly have anything to give anyway. I always tell myself, I will help out more once I am all settled but I don't really believe it deep down. And it feels good.
I’d be on board with both of these, provided that becoming involuntarily unemployed since the beginning of the year automatically qualified for the $2k/month. There should preferably be no phase out, but as long as people who are losing income through no fault of their own qualify, I’d be satisfied. As it is, it looks like this is just another half measure.
Show HN: I Made “Coronavirus Containment the Game”
I'm a non-German who lived in Germany, the US, and other places.

As you say 'it's impolite' to talk about the citizens in a nationalist way, yes, but Germany (and many other nations) are still deeply ethnocentric - it's by default. Almost everything about Germany is 'German' and when almost all economic, political and social concern on a broader level is about 'Germany'. It actually takes some intellectual effort to go beyond and think in terms of 'Europe' or even 'The World'.

'Not being so nationalist' is a social artifact of many nations these days, and I suggest it's just a healthy dose of self-awareness, but it doesn't change the definition of what the community is in the minds of citizens.

FYI I should point out that I don't think the US in a 'Germany model' would somehow result in the government building rocket-ships, but it would result in healthcare, better employment terms.
"""You see it in manufacturing. Contrary to conventional wisdom, American manufacturing output is higher than ever, but why has so much manufacturing been offshored to places with cheaper manual labor?"""

"""Is the problem money? That seems hard to believe when we have the money to wage endless wars in the Middle East and repeatedly bail out incumbent banks, airlines, and carmakers."""

This is interesting. They are investors, why is he asking the government to provide the capital for this. Shouldn't they be all over these great unexplored opportunities? How many companies that build actual physical stuff have they backed compared to yet-another-SaaS plays? I'm really curious how a pitch of "we want to build/manufacture stuff in the USA" would have went pre-Pandemic at a16z. Even trying to pitch hardware instead of software seems hard enough as is.

"""The problem is regulatory capture. We need to want new companies to build these things, even if incumbents don’t like it, even if only to force the incumbents to build these things. And the problem is will. We need to build these things."""

This is also interesting. Isn't one of the first things they want "moat, moat, moat"? Sure it's nice to ask for easier entry into markets when you try to fund the disruptor. But once said disruptor is funded they also want as much protection as possible.

"""Instead of attacking my ideas of what to build, conceive your own! What do you think we should build?"""

As a start, I would humbly suggest to rethink the model of "relocating all companies to where the capital is located" and move towards "move companies to the places where they should build most of their stuff". It's pretty mindblowing to me why software companies should be located in SV even when their customers are located elsewhere.
I would also argue that building stuff should be done in a more humble way than the typical VC-ambition. Build, test, show profit, grow organically. I think that could be more healthy than pump up 20 builders and hope one goes hyperbolic.

As an aside, the cynic in me thinks that Theranos would probably go through the roof right now if it was still around and waste a lot more capital than it did. It's easy to call for action, any action in times of crisis without being careful and level headed enough.
Here in British Columbia it's reality. I get my regular meds prescription refills using eqvirtual and when I got tendonitis during the lockdown I called the office and my doc called me back on the phone and totally causally just texted me a link to set up a video chat and we conducted our business just like that.

> The only possible thing the Aussies could do is block the websites, and that sounds like political suicide to me.

The first thing they could do is fine them. Google and FB might say "ha! but we don't have bank accounts in Australia!" and the government will simply collect from companies in Australia that have outstanding bills from Google for e.g. Adwords or Google Cloud.

Google can still run their websites to be reachable from Australia, but they wouldn't be able to do business in Australia. And what's the point of running an ad tech empire if you can't make money off of it?
I can see it being a spectrum.

For a big movie that people want to watch? Piracy probably hurt.

For a small indie that is in dire need of more exposure, then they're probably on youtube, but I can see how piracy could help.

If you're in the middle? Not clear.
Because of the SEO, most of the news sites are already clickbaits with junk information in them, it seems like this will grow a new industry: Link-tax-optimization.
I think it's a question of write vs. rewrite. Most archival backups are write-once in the sense that they're append-only, especially now that storage is so cheap nowadays (see: Amazon Glacier).

SMR performs generally fine except in the physical rewrite case. A 6TB disk is unlikely to see a lot of physical rewrites except in this pathological case of a RAID rebuild that people are complaining about.
I'm a Googler in Ads. This is a multi-faceted issue and there are tons of legitimate points on both its criticism and defense but IMO the backlash itself is deserved, especially for a number of anti-competitive business practices. But probably the exact same criticism can be applied to Apple, Amazon and Microsoft so I consider this to be more of a general tech sector problem where network effects tend to be amplified by its nature and perhaps better handled by regulations.

For privacy perspective, I'm not very satisfied with the status quo, but at least for Ads, privacy is now the top priority with a strict deadline so the situation may get improved. But I still think collecting less (or no) user data solves just a part of the problem; users still don't have understanding on what the real trade-off between their privacy and benefits to themselves/the overall web ecosystem from the ads they're watching is. Without this information, users cannot really make informed arguments and decisions on their privacy and ads. IMO, this is one of the fundamental reason of having significant discrepancies on the ads' perception across many people. But as this is not just a technical problem like 3rd party cookie but more of a subjective issue, this might be a much harder problem to tackle though.
No mention of differences in obesity rates, which while not politically correct, seems particularly important for covid.

This looks great, but this is similarly not encrypted, right? Google/Apple will be able to read all my notifications, no?

The only way I've found to do encrypted notifications is using Signal and signald, through a library I wrote:

signald isn't as reliable as I'd like, but it works well enough. Still, if there were a simpler alternative, I'd switch.
All these different costs have to be leveled for dollars in the same year to account for inflation etc.
That sounds like a massive privacy violation to me.

It seems like a lot of people get married and have kids just because it's the thing people do. Which I guess you can't really fault them for, but it is the root of a lot of society's problems as you say. I think it's great that my generation is seeing lower marriage rates and people waiting until later, I optimistically interpret that as a sign that people are starting to bring more intention into those decisions.

Here's a hot take: In a generation or two, once the technology matures, we'll start seeing a lot of people opting (themselves or their children) into reversible sterilization, and it will soon become the norm.
When somebody says ~“is this true” and you say ~“read the docs”, you’re dodging the question. It’s a pretty fair assumption that `tptacek and I are familiar with the docs and the concept of a Sybil attack. Even if we weren’t, you could just as easily say “Yes, the design of Handsake is based around a cryptocurrency, and our implementation involves speculation. For more info, you may want to check out the docs <here>.”

Instead, you’re deflecting by insinuating that we haven’t read the spec, and thus refusing to answer the question we’re posing to you.
