Simplest explanation I can think of: there's no reason to model this event as if all of its energy is emitted from a point source. As the NYT article put it, the size of the explosion is comparable to the orbit of Neptune. Meanwhile, two seconds at the speed of light is less than the orbit of Earth's moon.

So, if the gravitational effects originate from the center of mass of the explosion, and the gamma rays originate from some kind of Big Bang-like recombination phenomenon happening a few hundred million km away from the center of the expanding shell, that would easily account for the difference.
To domain switch, slightly: it's essentially a hash bucketing problem in a different guise at that point. The color space and visually distinguishable steps defines your hash bucket count (and kind of an equivalent to a memory limit), and maximally distributing your hashes across the available buckets remains roughly the same problem and you want a relatively well distributed, stable hash for basically the same reasons (color locality versus memory locality).

The perceptual color problem is an interesting "bandwidth" limit on available hash buckets.
Saying that PS/2 boards are "scanned" is inaccurate, as they trigger an interrupt immediately on a keypress.

It's like 20x better than every other product out there though. And their new video chat + screen sharing is pretty great. The bandwidth is far higher than any other competitors I've used.

My brother and I were playing 1080p videos on each of our screens and watching the other's, just to test it out. Obviously it wasn't full quality, but it kept the frame rate up and looked presentable at least to 720p.
That may be a compelling HN argument about the heroism of Elon Musk, but for a competitive car company, "pulling the rest of the industry forward 10 years in the span of 1 year" is a very bad thing.
I'm surprised the "humans don't notice 100 ms" argument is even made. That's trivially debunkable with a simple blind A/B test at the command line using `sleep 0.1` with and without `sleep` aliased to `true`. To my eyes, the delay is obvious at 100 ms, noticeable at 50 ms, barely perceptible at 20 ms, and unnoticeable at 10 ms.

Not to mention that 100 ms is musically a 16th note at 150 bpm. Being off by a 16th note even at that speed is – especially for percussive instruments – obvious.

On the other hand, if you told me to strike a key less than 100 ms after some visual stimuli, I'm sure I couldn't do it – that's what "reaction time" is.
Out of curiosity, what's the demographic makeup of your interviewees? I can see how someone might value diversity while feeling uncomfortable raising the point.

I've gotten a FTDI down to 2 ms RTT, so if done right (using isochronous transfer) you can get USB down to 1 or max 2 ms. Looking at the latencies quoted here and in the article it's certainly not the problem.

Notice that just getting a thread scheduled every 2 ms is already impossible for Windows, certainly one running a game. You'll get a bunch of outliers within the second. So even if you got your keyboard down to 5 ms, great, but you are not running an operating system that can reliably do something within that timespan!
Your sentiment is a good one, but your conclusion is mistaken IMO. For poor countries the old model of centralized fossil fuel infrastructure is not cheap, and its certainly isn't reliable.

The future of third-world energy security is distributed. Expect to see the same transformation as we've seen with telecom; third-world telecom largely skipped the copper and fiber in the last mile and even some of the backbone, and went straight to wireless. Likewise, these countries will benefit from skipping the expensive coal mines, coal trains, pipelines, power plants, and even some transmission infrastructure, and going straight to micro-grids. They may end up ahead of us in some ways.

Yes, the actual answer to the question is "because the pilots are trained not to hit the tail, since it's expensive and makes the passengers nervous."

It's a decent little article but it seems to not quite be on the same topic as the headline suggests.
"United States choose 'Promotes from Within' more than readers from anywhere else."

Can only speak for myself as an Australian, but i initially took this as some kind of "Anthony Robbins" type bullshit motivational phrase or american corporate marketing nonsense statement.

Now that i pause and ask myself to reframe it, presumably in its intended form, my second natural response is "well, where else would they promote from?", thus making it a truism.

Only when i pause even longer would I consider it as asking about the phenomenon of needing to job-hop to get ahead.

But in short, i don't think the phrase captures a universal intended meaning very well :)
Weird, I find Discord's audio quality especially to be terrible.

And their lack of scalable monetization leads me worried about its longterm success as a platform - they are adding more cost-intensive features and continuing to try to support it with what is essentially a $5 monthly donation model.
What I mean to say is that there is an original sin in our marketplace and that sin in EMTLA. Our society doesn't really like the idea of the sick and poor dying just outside the ER's doors (like in a truly free market) so we have EMTLA to make sure that doesn't happen. It's also reflective of America's cultural attitudes towards death and the amount of money that is spent buying our loved ones just one more month, week, day.

All of which is to say that generally we seem quite uncomfortable with the idea of someone else being able to afford more "life" than we can. So maybe we should just toss the idea of marketizing our healthcare entirely.
They mentioned it being a likely culprit in the article :)
Protected class usually refers to groups protected against discrimination by law.
Definitely agreed. I was introduced to functional programming via Pyret, which is similar to Racket and draws from HtDP in terms of pedagogy. It's a much gentler introduction than being thrown to the wolves with Haskell or OCaml. I'm sure one could learn FP effectively with those languages too, but if you're still trying to wrap your head around the functional paradigm you don't really want to have to stumble across words like "endofunctor" while reading the documentation. I even have a good math background but I would have found that confusing at the time.

Ya exactly.. with Uber it's just yourself for risk.

Wag is one stop closer to "I trust you with something import to me, don't break it". I guess the ultimate test would be "uber for babysitting".. some stranger stops by and picks up your kid and takes them to the park.

Where you value your pets varies a lot by culture. But I value them much closer to my children than myself.. which would make Wag a nogo for me.

Edit - Not to make you paranoid, but my event happened at my vet. Turns out my vet abused 100s of dogs. No criminal charges. She is under review to MAYBE have something happen to her license. Or maybe have some additional oversight. After abusing and killing many animals.

No, but it would increase the chance of you noticing that person and taking corrective action.
Even if there isn't a normal exchange, there's usually a market in options and futures. And if it isn't a full market, there are players who can make bespoke deals. Someone who holds on the "long term" exchange along with a costless collar (long OTM put / short OTM call) has much less economic exposure to the stock but has "held" it for the same amount of time.
I work at a place that's very not diverse, and the groupthink can be suffocating. It's not so much as having sufficient nonwhites on your team, it's more about having people with different ways of solving problems. In my experience, a lot of mid-level problems get solved by inviting over a low-level programmer and have them look at the problem for a bit, asking questions about it.

Having a good distribution of perspectives is much more important than having a multi-ethnic hivemind.
We've debated it internally, but currently have decided to stick with Slack (free version)
It's a plausible story. Fine to present as a parable, but we should stop presenting it as true unless we can find a reliable source for it.

Until today, I believed it was true. It was told to me as an undergrad, by a professor who believed it himself.
You might want an upper limit, so either logistic growth [1] or something like 1 - exp(-(T + T_0)) feels like it makes more sense.

I especially like logistic growth for having slow growth at the start and end, only growing quickly in the middle.

> can I short on the normal exchange and buy on the long term exchange for some free voting power that increases over time?

Buying voting power on the long-term exchange isn't free, your capital is allocated. You have finite capital. Your cost for each unit of voting power declines perpetually so long as you hold it, it never goes to zero (free).

You can view the shorting as paying for your purchase in the long-term position, however you could view it that way for shorting any other company just as well. It's meaningless as a premise or issue.

To put it in painfully simple terms, just because the "hacker's code" contains Cyrillic, it doesn't mean Putin was behind it.

As a layman, "fourth-party collection" sounds a lot like "false flag" to me... is there any key difference I'm missing?
Oops, yeah I just got to that part. My fault for not reading past the conclusion before posting.

Still, I guess in a way, timing it from the start of a key press is the most real measure of actual latency when you want to press a key. It's just got nothing to do with the processor etc.
do serious gamers avoid v-sync ? even at 120Hz they get at least ~8ms * 2(double buffer) latency right ?

Can you give more explicit examples of the bad audio quality you experience? I'd be happy to forward this onto our native team to look into if there are some concrete things they can look at. Generally 99% of the audio issues we see people experience are due to ISP/peering/DDoS/etc issues, most of which are handled automatically by our servers within a few minutes.

The patent for Autotune can be found here: https://www.google.com/patents/US5973252?dq=5,973,252

My (very non-expert) reading of the patent is that it uses sample reduction and some specific features of the periodic form of the human voice to simplify the math involved in the auto-correlation routine. Although this routine does seem to be unique as far as I know, I wouldn't be surprised if it shares similarities to other techniques to reduce correlation complexity.

It's worth noting that the instance migration basically null-routed the redis VM for a good 30 minutes, until we manually intervened and restarted it. The instance was completely disconnected from the internal network immediately following the migration. From what we could gather from instance logs, the routing table on the VM was completely dropped and it could not even connect to the magic metadata service (metadata.internal - we saw "no route to host" errors for that). This is a pretty serious bug within GCP and we've already opened a case with them hoping they can get a fix. I think this is the 4th or 5th major bug we've encountered with their live migration system that could have, or has led to an outage or internal service degradation. GCP team has seriously investigated and fixed every bug we've reported to them so far, so props to them for that! Live migration is incredibly difficult to get right.

We believe this triggered a bug in the redis-py python driver we use (specifically this one: https://github.com/andymccurdy/redis-py/pull/886) that made us have to rolling restart our API cluster in the first place, to get the connection pools back into a working state. redis-sentinel had appropriately detected the instance going away, and initiated a fail-over almost immediately following the instance going offline, but due to the odd network situation that was caused by the migration (absolute packet loss instead of connections being reset) - the client driver was unable to properly fail-over to the new master. We already have work planned for our own connection pooling logic for redis-py - as right now the state of the drive in HA redis is actually pretty awful, and the maintainer doesn't appear to have the time to close or look at PRs that address these issues (we opened one that fixes a pretty serious bug during fail-over in march https://github.com/andymccurdy/redis-py/pull/847 that has yet to be addressed).

>I know next to nothing about faxing - how is the transmitted data secured? Is it?

Traditionally, transmitting a fax was just making a telephone call so it was vulnerable in the same way that any telephone call was to wiretapping. With fax services as exist today, you're basically emailing them a PDF and they're then sending that as a fax to someone's phone number. (Or the reverse.) So there's no real security other than that provided by the telephone network and the service's internal controls.

I had efax for a number of years but I believe they eliminated the free incoming fax number for free accounts and I haven't actually needed to send or receive an actual fax (as opposed to a scanned document) in years.

I also wondered if diversity would be more important among HN/San Francisco folks! Right now, I don't have sufficient data to say either way. I actually predicted "Actively Practices Inclusion" to be selected more frequently in the Bay Area, or at least California and New York, but this doesn't seem to be the case either.

Re: interviews, you're right. It's not brought up very often. Since working on Key Values though for the last several months, I've learned that many women refuse to be the first female engineer at a company. While diversity isn't always visible, many people will simply look at the current team members and draw conclusions themselves.
I work remote currently, but I've spent many years working in offices. In those times, as an introvert, I've greatly preferred to eat outside the office, to avoid feeling expected to socialize during what would otherwise be a nice 30-45 minute break from other people. That isn't to say I don't like other people, but it is exhausting to be continuously around people who you ought not to ignore, especially if you aren't actually interacting with them (but might be called upon to do so at any moment), and having a break most days from that makes it doable.
What do you mean by "zero egos?"
Semi-related aside, several of the original OKC founders are now at Keybase, and I feel like part of that blog culture you recall fondly is part of why Keybase articles get such high regards here at HN, beyond just the coolness of the tech they are working on.

Whether I subscribe to read the emails or just to archive them for later reference or for feeding them into a robot that distills out the most important information for me ... that's simply none of your business and you shouldn't try second-guessing me if I have explicitly declared my intentions.
Yes, and something like a touch interface is very obvious, too.

You can plainly see that 100ms is an eternity. While keyboards aren't the same thing, but high latency is noticeable. I had to change a keyboard because of the near eternity of when I pressed a key and when it registered on the screen. The difference between the old and the new is quite stark.
One thing that I've noticed helps is swapping the region for the server. It doesn't result in any noticeable outage on your server and has resolved any voice quality issues that we've run into most of the time. Usually just swapping between US-Central and US-West in our case.

Didn’t watch good enough. There are mechanical keyboards in the review as mentioned below. My bad. Original comment below for future reference.

—- original comment —-

True gaming keyboards have
mechanical switches which activate on first key press, not on full key down. Bit disappointed no mechanical keyboard was tested as they are perceived to be the ultimate keyboards when speed matters.
Actually 5mph is quite fast. When I do a rolling stop in my car, it's typically on the order of perhaps 2mph, which is a speed where I can proceed in 1st gear without coming to a complete stop and then having to start again from a stop.

I just ran the math, the kinetic energy of a 2000kg car at 5mph is the equivalent of the kinetic energy of a 100kg bicycle+cyclist at 22mph.

I absolutely roll stops, but it's important to recognize what we might miss. My old commute had a series of 5 (virtually useless) stop signs in a row, an arterial with very little cross traffic but tons of 4-way stops. (should have been roundabouts). The routine of the drive, and the necessity to stop, the focus on the stop signs and stop lines, and the almost total lack of pedestrians meant that I'd occasionally start off before noticing the cross traffic or pedestrian. (yes, this is more of a boy-who-cried wolf kind of thing). Also, modern cars are amazingly difficult to see out of-- pedestrians can be hidden behind thick airbag-containing A pillars. When you're moving, however slowly, everything in your field of view is also moving. When you stop, it's much easier to spot objects that are NOT stopped.

Hell, just last week I was making a left turn on my bicycle. As I approached the intersection, I slowed, looked each way up the road several times as my sightlines improved, and just at the moment I committed to my turn and began to proceed, I saw the minivan coming from my left that was on a collision course with me; I locked up my brakes and stopped just in time. I know I looked exactly where the van was coming from, multiple times, but somehow missed it. I suspect, again, our brains are much better at seeing what's in motion when we are ourselves stopped.

I don't believe this ordering has anything to do with the languages themselves but rather rather the projects I needed to get done at the time.
When someone tells me "think of all you can learn!" When trying to sell me on a project / job I always say, "as long as it comes with an ever growing pay check"

To me it's just a way "the man" tries to keep us underpaid. Interesting work or experience is not a substitute for money. In truth, the more learning required, the more stress (typically) and thus, the more money I'd like for my services.

It is understood that there will be those who buy bottled water where public utilities provide clean drinking water for all. Roughly 10% of the UK population are contributing to private health plans (https://www.theguardian.com/business/2017/jan/16/private-med...). Apparently, the % of population fully covered by such plans is lower still (at under 1%). While this is a huge waste, this is not what I was alluding to. I have no argument to make if everyone in the US had access to health care comparable to that provided by the NHS.

I've spent some time working with ill-defined scenarios/flows so having validation doesn't look to be something bad to me. Although I had never worked in an environment that could be said to be fixated on it, so I guess I'm missing something.

So I wonder... what's bad about this? (Or I misunderstood what this is about?)
