A black hole has the same escape velocity as a star of the same mass, as long as you are well outside the swarzchild radius. Inside or near it, the effect of general relativity makes things very weird.

In case of mostly anything else, Newtonian physics apply correctly, and the relevant thing is mass (and distance from the center). The escape velocity from a body is sqrt(2GM/d) where d is the distance from the center of mass, M is the mass of the object, and G is the universal gravitational constant.

Note that if the sun was replaced with a black hole of the same mass, the orbit of the earth wouldn't change.
Although their (commendable, IMO) limits on data collection may be a handicap, I think the extremely narrow Siri API is a bigger problem. At first I thought Apple was behind Amazon in terms of opening up the possibilities of using voice commands for more than a few simple things. But so much time has gone by and Siri is still so limited that I'm beginning to wonder if they have any intention of catching up.
Downloading API kits and actually getting those things you built approved for distribution are very different things though.

NSQ has served us pretty well but long term persistence has been a massive concern to us. If any of our NSQ nodes go down it's a big problem.

Kafka has been far more complicated to operate in production and developing against it requires more thought than NSQ (where you can just consume from a topic/channel, ack the message and be done). More to that, if you want more capacity you can just scale up your services and be done. With Kafka we had to plan how many partitions we needed and autoscaling has become a bit trickier.

We now have critical services running against Kafka and started moving our whole pipeline to it as well. It's a slow process but we're getting there.

We've had to build some tooling to operate Kafka and ramp up everyone else on how to use it. To be fair, we've also had to build tooling for NSQ, specifically nsq-lookup to allow us to scale up.

We have an nsq-go library that we use in production along with some tooling: https://github.com/segmentio/nsq-go

Which "good" ciphersuites [1] were usable in TLS 1.0 when BEAST was made public in June 2011; with BEAST affecting only TLS 1.0?

TLS 1.0 per RFC 2246 defined DES40_CBC, DES_CBC, 3DES_EDE_CBC, RC4_40, RC4_128, and IDEA_CBC.

RFC 4132 added CAMELLIA_128_CBC and CAMELLIA_256_CBC in 2005, RFC 4162 proposed SEED_CBC in 2005, and RFC 6209 in April 2011 informationally specified ARIA_128_CBC, ARIA_256_CBC, ARIA_128_GCM, and ARIA_256_GCM, but the GCM ones only work in TLS 1.2 or later. Same story with CAMELLIA_*_GCM.

Informational RFC 5469 in 2009 deprecated the use of DES and IDEA ciphersuites, so that left RC4, 3DES_EDE, the Korean ciphers SEED and ARIA, and CAMELLIA, with the block ciphers in CBC. Pretty much no one supported the latter three, and when Mozilla rejiggled the ciphersuites in 2013, support for these was removed entirely [2].

Your point still stands about BEAST being a flaw in the glue rather than the ciphers themselves, but I believe the parent poster makes a stronger point about the complete lack of AEAD constructions before TLS 1.2, and the lack of other stream ciphers which were more self-contained in TLS 1.0 and thus unaffected.

A little UI comment if the the creator is reading this. It actually took me a while to find the search/filter button.. only to see that it's actually on the bottom. Perhaps make it more visible (on top maybe? and show the form right away instead of having to click the filter link).
Is it really that dramatic a difference? I suppose it must be, if they're building it, but it's strange that no one has done this before if it really helps.
I think it's less about throughput and more about durability guarantees. Kafka producers can specify the number of 'acks' (brokers which have written the message to disk) when they produce a message and the request will only return successfully if that can be done.

From wikipedia [1]:

>Atmospheric and gravity drag associated with launch typically adds 1.3–1.8 km/s to the launch vehicle delta-v required to reach normal LEO orbital velocity of around 7.8 km/s (28,080 km/h).

So it'll help. Also significant is the ability to base out of an airport and launch closer to the equator.

If I understand you correctly, you want to be able to join the results of multiple sources? You can do something like that with a library I wrote, riko [1]. A simple example would look something like this:

from riko.modules import join, fetch, fetchdata

rss_url = 'http://site.com/rss'
json_url = 'http://site.com/json'
json_path = 'path.to.data'

fetch_conf = {'url': json_url, 'path': json_path}

rss = fetch.pipe(conf={'url': rss_url})
json = fetchdata.pipe(conf=fetch_conf)

joined = join.pipe(rss, other=json)
next(joined)

You can see the docs for the `join` pipe here [2].

NSQ has been (IMO) far far easier to operate than Kafka has been. With Kafka you need a Zookeeper cluster in addition to your Kafka brokers. Not to mention developing against NSQ is pretty simple whereas Kafka you need to think about partitions and offsets.

If you're worried about data loss, Kakfa can be what you're looking for (but takes a lot to learn how to operate it correctly).

I had a similar issue with Seveneves recently. I had a strong science-based disagreement with the idea of Izzy always keeping its anchored asteroid facing into the oncoming atmosphere of LEO, which I was sure was impossible because it would be facing the rear as often as it would the front, because objects in space/thin atmospheres don't fly and don't maintain a constant relative orientation just because they're orbiting something. To me it seemed as dumb as a spacecraft that had to constantly have its engines firing behind it just to stay in orbit.

It wasn't until I shared this frustration with a smart friend, and he pointed out that it actually is possible if the space station has a rotational period equal to its orbital period, that I realized I was wrong. The author was indeed being smarter about the science of it than I was, and had done the research. And, forget just the future part of it; the ISS actually currently flies with a specific constant relative orientation through the atmosphere so as to minimize air resistance, using, you guessed it, a rotational period equal to its orbital period, plus occasional corrective actions from gyros and thrusters.
Being a native English speaker, having taken a few years of Russian back in college, and having just recently been mutually trolled by some coworkers into completing the Duolingo course on Esperanto, this notion of simple English being easy strikes me as implausible.

First, I'd argue that simple English compares unfavorably to the expressiveness of Esperanto given a similar investment of effort. Due to the way that Esperanto uses prefixes and suffixes to form more complex ideas, it takes a ludicrously short amount of time to start playing with and bending the language in what I can only assume are entirely legit ways.

Second, Russian spelling is pretty darned regular / phonetic. I'll believe you that spelling is taught up until grade 11, but for the life of me I have no idea why. Given my extreme reliance on a spell checker to save me from embarrassment English, I'd posit that it's by no means because English is easier to spell—and my undergraduate major was journalism. Maybe in we in English speaking countries just give up on doing English sans spell checker earlier? My comprehension is pretty mediocre in Russian, but I can certainly sound out unfamiliar words and spell spoken words reliably...

Also, a plug for the Duolingo Esperanto course: It's great fun, and is a very short path to getting a basic grasp on another language. Plus it has a baked in idealism that I love for the same reason I love Star Trek (see: https://www.currentaffairs.org/2017/03/the-regrettable-decli...)
FWIW, the speaker on the original Amazon Echo isn't very good.

Pg_squeeze: A PostgreSQL extension for automatic bloat cleanup
It's World No Tobacco Day today and we developed a smartwatch app which helps people quit smoking, on Android Wear 2.0 (atm), here is how it works:

-> we automatically detect when a person smokes (motion recognition)
-> from here you are suggested a best time to smoke next (we slowly increase their time to their next cigarette)
-> when you wait until after the suggested time you receive points which can be converted into Starbucks credits

Here are a couple quotes from our initial testers; looking to get 1000 user market study to confirm our results!

“Cue is a helpful app because it provides positive reinforcement that rewards delaying my next cigarette." - Adrian

Amazon approval is basically a rubber stamp. Can't say the same for Apple's. I'm also not aware of Amazon denying anything for competitive purposes. Amazon is happy to let Spotify on their platform, despite having a music service of their own, for instance.
If I recompile blake2sp with "/O2" optimization, it improves to 171MB/sec.

Too slow! You're doing something wrong or measuring some slow implementation :) It should be more than 500 MB/s.

Therefore, every hash had no optimizations to keep the comparisons apples to apples.

That's not apples to apples at all. Most performant code is written specifically to be optimized by compiler. Use /O3 for benchmarking. Also, you just wrote that you were measuring a hand-optimized assembly version and then compared it to a C version compiled with optimization disabled? O_o

I chose 500MB because I wanted the fastest hashes (CRC32, MD5) to take at least 1 second and many data sizes I want to hash will be 10GB+.

Then call the update function with a reasonable 8K buffer many times. Using such large buffers will generate a lot of noise in benchmarks.

Speaking of JS, you can try my newer implementations/ports by cloning https://github.com/StableLib/stablelib. run ./scripts/build, cd into packages/blake2s (/sha3, /sha256, etc.) and run: node lib/.bench.js Note that SHA-3 (and SHA-512, BLAKE2b [not implemented yet]) is slow in JS compared to SHA-256, BLAKE2s, etc. because it uses 64-bit numbers, so in JS I have to emulate them by using two 32-bit ones for low and high bits.

A fair point. I never use the dictation, but I often try to use Siri when the phone is out of reach. My Echo understands me when I speak at a conversational level from across the room with the faucet running. If the dictation is spot on and Siri is still bad when speaking directly into the phone, then yeah, that seems pretty damning.
I wouldn't say that Amazon's is open. I would say it is much more open than Apple's, though.

https://en.wikipedia.org/wiki/DART_Light_Rail -> System Length 93 mi (150 km)
https://en.wikipedia.org/wiki/Trams_in_Melbourne -> System Length 160 miles (250 kilometres)

However, your point that the decentralization plays a difference is very valid. The Melbourne network is a dense grid which serves a much more compact area whereas the Dallas system consists of a small number of lines that stretch very far out into the low-density suburbs. Hence, far fewer people are near a DART station.

Hey sorry but this

> In addition, too much of ML is .... short on math guarantees.

is utterly false. As I keep telling you need to upgrade :)

In fact I will level the same exact criticism on standard stats. NP lemma is fantastic math but of little practical importance because you rarely ever know the densities. Most of the time 'test of hypothesis' is a bad joke catering to a contrived scenario. Real problems are rarely about 'is it H0 or H1'. Estimation is typically more useful. Stats have long suffered from their fetish for parametric models, asymptotic normality, asymptotic guarantees and what i feel their greatest deficiency: the focus on parameter estimation rather than guarantees over prediction. Parameters and parametric models are convenient fiction, nobodody has seen them, will ever see them. What's all the fuss about estimating a fictional object to great accuracy under strong assumptions in infinite time about.

Made sense a century ago though. If their purported utility is in aiding prediction then why not go after the real deal, that is, non-asymptotic guarantees on prediction in a distribution free / nonparametric setting. That is what ML does. Please dont characterize ML by bad examples and work in progress stuff. I do know nonparametric stats exist but thats not the face of stats that people get to see, but even in those cases the focus is usually on accuracy of estimating a functional.

I was deliberately harsh on stats in my comment to offset some of the wrong things you mentioned about stats, but the relation between ml and stats are really not adversarial. I see ML as a course correction for stats: focus on prediction guarantees and adding some muscle in two areas (i) algorithms for scaling (ii) optimization. In anycase i know where both the tribe hide their dirty laundry :)

That said I strongly agree that Ml is indeed applied math a mix of probability, optimization, functional analysis and algorithms/Datastructures

Look at this analysis of the Falcon 9 flight profile, in particular the graph at the bottom right: https://www.reddit.com/r/spacex/comments/6303ko/falcon_9_ful...

The majority of the horizontal delta-V is produced in the second stage. The job of the first stage is to a large extent just to lift the second stage out of the densest part of the atmosphere, to minimize drag for the second stage. A plane can do the same thing, and possibly more cheaply in certain scenarios (well, that has to be Allen's plan anyway).
