Alternatively: "how human beings rose from the lesser hominids in 70,000 B.C.E."

There's a serious theory it was this bottleneck where humans were confined to environments without natural preditors (seaside cliffs like those near Cape Town) and where social interaction was a necessity. Those with higher intelligence, particularly social intelligence, would scored more mates in that environment. And thus we had a runaway intelligence arms race that separated modern humans from their immediate hominid ancestors.
Low stress?

Did you ever have to deliver to someone who is away? to an address that doesn't exist? to an address that exists but is located at the wrong place? what when it's inaccessible or has no bell?

That's what you get to deal with every single day, you never know where you gonna be or what's gonna go wrong the next hour. Meanwhile, your delivery time is accounted and customers can complain back about you for anything.

Virtu trades far more than 3 million shares a day. They may even make 3 million trades a day.

If you've seen a system like this in action, it's a beautiful thing to behold and cannot be mere luck. Transactions stream in constantly. It's not just one big, lucky bet, but thousands of tiny bets with a slight edge. A plot of profit & loss with respect to time looks like an almost perfectly smooth upward line. And if you're good, you can do this every single day for years and years.

Still, I wouldn't say guys like that have beaten the market in a real way. I've certainly never felt like I did. This style of trading doesn't need outside capital and can't scale. If I gave you $100 and armed you with a scalping bot, I bet you could easily turn it into $200 buying hot tickets on Ticketmaster and reselling them. But would anyone call you a genius trader? Could you do it with a million? A billion?

As a business net of all costs like employee compensation and technology, returns to owners are pretty lousy. Compare owning Virtu stock to an index fund since their IPO. Ouch.
On the other hand, Twitter also has a right to free speech. They're perfectly within their rights to promote their own opinions or viewpoints. I would assume that also includes the right to selectively amplify the voices of other based on agreeing with their viewpoints.

Because Twitter is a platform for the communication of others, they find themselves in an ironic situation: adhering to the principle of free speech means giving up, or at least severely restricting, their own ability to exercise that right. I think it would be noble of them to accept that restriction voluntarily, but it would be problematic if it were required of them.

Note the difference between 'tax avoidance' and 'tax evasion'.
It's more about an eventual massive drop in media coverage. Like it or not thanks to this account only, twitter is in every media outlet EVERY day... for free.
That's extremely powerful and undeniable.
Trump is hardly making rational, intellectually cogent or even factually correct criticisms of the left on Twitter. He's just making an ass of himself, so the loss of his account would probably help the right more than it hurts them.

I don't think he should be banned, because he's actually quite tame as far as Twitter goes. Sure, his spleen-venting is probably doing real harm to the cultural and political climate of the country, but that is one of the reasons he was elected... brick through the window of the establishment and whatnot. But if he hasn't violated the terms of service, then he has as much of a right to pop off tweets as anyone else.
Tor hides the identity of the service provider to third-party eavesdroppers. You might know someone and have gotten the onion address of a file upload server from them, but not want the government or your ISP to know who you're talking to.

It also hides the a service provider's physical location (well, their IP address and hence location in the network graph) from even a user that knows their identity. You might know that I am an investigative journalist you're trying to send information to - or, given the origin or Tor, maybe you're a spy and you know I'm your handler - but I don't want to give away my location.

There are also a lot of use cases where the user doesn't care that much about knowing who the service provider is, and the service provider cares a lot about hiding their identity (enough so that they would not provide the service if they could not be anonymous).

For the example of, say, political commentary - often what you care about there is less the real-world identity of a person, and more their persistent identity and reputation. On the other side of the equation, though, in some environments people might not feel safe expressing their opinions at all if those opinions could be traced back to them.
With services like ontrac and their inhouse delivery they are intentionally scraping the bottom of the barrel for small-van delivery operating costs (salary, benefits, recruiting/hiring practices and training, vehicles).

Am I taking crazy pills? If he had said, "...then I'm going to order a nuclear strike", that would have been explicit. Saying "they won't be around much longer" is a veiled threat, the threat is implicit.
They should be able to remove his account and decide not to.
Interesting theory! Do you have a link or reference where that theory is expanded more?

My guess is either (a) they're pulling the original price from a DOM element and not checking if there's also a sale price (most sites with sales prices will show the original and the new price), or (b) looking for schema.org product data and not looking at the correct item [0].

Ask HN: What have you done which no one else in the world haven't?
Is there something which no one except you have done in the world? If yes take this opportunity to share it with HN.
Bingo. We were taught not get in a car with strangers or meet people online. Uber and Tinder are things.
Except when things are convenient and we're benefitting from it, it's easy to explain away the negative consequences that befall others.

Think of all the engineering effort to create dark patterns or make it easier for people to buy stuff. I won't work on ads, but a lot of other engineers are okay with it, especially if the money is good.
Well, Mastercard ALONE processes well over 3.5 billion transactions per day, compared to Bitcoin's 300,000. So without knowing anything at all about how energy-efficient they are, we can say it must be many, many thousands of times better, considering that otherwise there wouldn't be enough energy on the planet to power them all.
TBH, I've had a Twitter account since 2009, but the only reason I will visit their site once a day now is to check DT's Twitter feed to see if I have to watch out for anything that will impact (a) my industry (b) the financial markets and (c) world peace. No word of a lie.

Twitter is probably marking off my visits as a solid 'daily user activity - this person keeps coming back to our platform within 24 hours on a regular basis'. But aside from checking his feed (and sometimes getting drawn into a senseless argument thread), I rarely post my own stuff on there any more as it is just a futile exercise in shouting at the void.
I thought about building a box that auto-locks when the weight of a package is detected in it. Can be a simple flap on the bottom that moves a latch. The lid would be a double lid -- an outside lid with a key lock, and the inside frame that the flap-activated latch slides into.
Twitter and other social media networks should be seen as common carriers and not interfere with what people post. Twitter should be able to exercise their free speech on their own twitter account, not by censoring other users.

It is ideal for social media to be common carriers the same way the net should be neutral.
They would need to MITM you. But take into account that it doesn't need to be Savitech. If Savitech was compromised, an attacker could get access to their private key.

In a sense, your security becomes dependent on the security of Savitech. I imagine their private key is not as securely stored as a real CA would store theirs. (e.g. with Superfish, Lenovo included the private key on all laptops, for anyone to grab[1])

Gravity.io – New Android Physics Game
https://play.google.com/store/apps/details?id=com.gravity.io
Gravity.io is a physics puzzles game.
The goal of the game is simple - to guide the diamond ball to the yellow cup, collect all stars and complete the level.
To do this, you have a physical set up consists of bricks, springboards, air bubbles & your fingers. Use them to perform the physics task.
In each of the addicting levels you will need to get the diamond into the cup, sounds simple right?
Your timing and finger sensitivity are the main keys in this game.
Show how clever you are.
Enjoy!
You can have cryptographically anchored pseudonymous trust, which is what Tor does. In many ways it’s stronger than the kinds of trust you run into normally.
The thing about the Toba catastrophe theory is that the best evidence for it is "there was a massive eruption ~73K years ago" (the largest in the past several hundred thousand years). Which is to say, there is no archaeological evidence of depopulation. I don't know the genetic evidence well enough, but Wikipedia's presentation of that evidence is non-sensical, and I don't think there is unambiguous genetic evidence that "humans were relatively inbred ~70kya."
Militaries are good at making horrible UI. :-) I used to work at early warning radar, that should notify our tops about incoming ICBMs. When there's a target, classified as "suspicious" or "something that's going to fall onto {our, neighbour} territory", the following happens:
- very loud sine 1200Hz tone starts sounding
- the only output device, "fast-printing device", starts dumping hexdumps of internal structures to long 10cm wide paper (like toilet paper).
- the whole chain of command start yelling to each other (downwards), demanding data and info about the target.

So as the last person in that food chain, you're in the middle of panic, 1200Hz are drilling into your brain, damned thing prints hexdumps, and you need to apply binary shifts and ANDs, convert from floating point hex to decimals and pray that there's enough paper in damned FPD.

I could never imagine worse UI, it's strange that we didn't start WW3 in those conditions.
It makes sense, People will keep buying and adding computational power until the return on running the machines is lower than the cost of electricity. when the "cost of a bitcoin" rises faster than the cost of electricity it can directly lead to an increase in use. So unlike any other thing we run on computers for profit... bitcoin has a direct cause and effect relationship.
>TL;DR: they do this because they can, and they can because you let them.

You may be passionate and well informed enough to have the strength of conviction to take appropriate action, but most people are not.

Nothing will change unless you can affect the behavior of others. You will be fought every step of the way: for the company, this is a fight for survival.

>they can because you let them.

What does this statement reveal about your internal dialogue? You can't expect people who don't understand or who aren't involved to take action. You are delegating your responsibility. Perhaps it is good for your ego, but I can tell you how it turns out.

A more appropriate statement would be, "because I let them."
A better rebuttal is that UAC is not a security boundary and bypassing it is trivial.
I love Stafford Beer's "The purpose of a system is what it does" here. It separates fact from intention when reasoning about systems. The engineers that Kumail catches offguard are (in my opinion) confused because the issues he raises are so far from their intentions.

Ironic counterpoint: I now notice that the deactivation itself is 'newsworthy' and has been picked up by Reuters et al. Does this mean that this particular employee is now exempt from sacking or other disciplinary measures because what he/she did was 'newsworthy'?

What a tangled (inter)web we have weaved...
Lock Screen Note Taking on Chrome OS
A number of people have already attacked one of your fundamental assumptions about low skilled labor. I think one way to say it is you're making the assumption that what you call "low skilled labor" is in fact "zero skill labor." I think you underestimate the level of skill required to deliver goods efficiently and quickly, and yes, the cost that is involved in it. (to be fair, you seem to be saying that I am overestimating that skill in your first sentence.)

Also, "one off consumers. Varying routes every day." Well, delivery company employees will have precisely fewer of those because their job is to deliver things, seems like the reason not to trust Amazon drivers over Fedex.
They need to fire that employee. Apple, Netflix, and Tesla don't put up with this, because they have strong leaders at the helm. The amount of hypocrisy and constant outraged that comes out of the bay area makes me sick to my stomach. I used to be liberal, then I moved and lived in SF for 5 years.

To quote; and I'll be sure to get it right (unlike the Texans owner) "the inmates are running the asylum".

Interesting to hear the execs talk about iPhone sales in a manner that explicitly refutes the rumors of iPhone 7 outselling 8:

“They instantly became our two most popular iPhone models and have been every week since then.”
Oh, not this again...
Obama wasn't setting policy or doing "diplomacy" on Twitter. If he were, I'd say the same thing. People asking for Twitter to ban Trump aren't all doing it because of their political "side" -- his use of the platform is harmful on its own.

There's no way you can trust this to be unbiased, and the same can be said about the MariaDB comment they're responding to but don't directly reference (I've been unable to find it.)
You still have to get a correct onion address from a reputable source otherwise how do you know that you're going to the right onion and not a malicious mirror or something?
So somehow there is a chain of trust, not too unlike the traditional PKI model.
Growing Energy Labs Inc. | Engineering Manager | Melbourne, Australia

Growing Energy Labs Inc. (Geli) provides software and business solutions to design, connect, and operate energy storage and microgrid systems ranging in size from residential to utility-scale, as well as grid-tied, microgrid, and off-grid systems.

Geli is currently looking for an Engineering Manager to join the team in Melbourne. This role will be responsible for managing and growing our 10 person Melbourne based engineering team, ensuring collaboration with the 20+ person San Fransisco based team, and working with the local business development resources to ensure projects are aligned to technical and resource capabilities.

If you have an interest in energy, are comfortable navigating the rapidly maturing energy storage market, and feel up to the challenge of managing a regional headquarters then drop me a note at ben.harris[~at~]geli.net.
Correct. It's spatial intelligence.
You make it seem like you disagree with the person you’re replying to. But don’t you see? You agree with him. That exactly what he’s saying: what Twitter legally can do is different than what they should do.
Autopilot is not a standard mid range car feature.

"Enhanced Autopilot adds these new capabilities to the Tesla Autopilot driving experience. Your Tesla will match speed to traffic conditions, keep within a lane, automatically change lanes without requiring driver input, transition from one freeway to another, exit the freeway when your destination is near, self-park when near a parking spot and be summoned to and from your garage."

You can get adaptive cruse control for more reasonable costs, but lane changing takes a lot more awareness around the car.
thankyou for the downvotes, it was a genuine question. I see a lot of this bot-like behaviour on HN these days
I believe you'd could get the same ratios when unit costs go down (e.g., raw materials costs drop, fixed costs such as tooling are amortized, and so forth).
People don't tend to be equally sophisticated buyers across all product categories. Mac usage is definitely a metric for buyer sophistication, when we're talking about Mac sales!
Awesome list! I’ve been a death to stock photo subscriber for a while and love their work!
I don't think i'm knowledgable enough to do anything other than refer you to sharding (we don't need to store the whole chain, just like in distributed computing) and the recent paper by Vitalik (Ethereum) and Joseph Poon of Lighting Networks on Plasma, which seems like MapReduce/Hadoop/Spark stuff with a blockchain

Logitech announces a development kit for using keyboards in virtual reality
Yes. The web didn’t get “dumbed down”; it got more diverse. This is a very good thing.

The issue is that technologists insist on making a clear distinction between the “user” and the “developer”. If you hide the number of web requests away in an obscure, borderline illegible, “developer tools” pane, is it a surprise that the average user has no idea about what is going on in their browser? No one is interested about building a browser, or even an operating system for that matter, that focuses on making things understandable, learnable. That is part of the reason why we end up in situations like the ones described in the article.

Regarding differences in intelligence, that is not a particularly relevant point here. People have differences (plural) in intelligences (plural). Even one person has diffferences in intelligences throughout their life at many different scales - I was much better at physics back in college than I am now because I practiced it more, and yet I wouldn’t say I was more intelligent 10 years ago than I am now even though I could solve physics problems faster. There are even pretty big fluctuations in my intelligence in a single day based on how tired/frustrated I am, if I have concerns at the back of my mind, etc. All of these statements aren’t really relevant here, because we have systems that deliberately obfuscate how they work, which is a much bigger problem.
This is why even the phrase "hate speech" is dangerous -- it ultimately has no concrete meaning so it's definition is ever-expanding. It's an ideal term to use as a basis for censorship and political violence.
but a higher standard of what? His words will be more scrutinized but beyond that should a higher standard of censorship be implored? If that's the underlying suggestion than who's this arbiter of good speech and how might that go about working?
If it wasn’t on purpose, then they must have some interesting special logic around his account in particular (maybe others?) that was maybe accidentally altered/enabled. I’m just curious what the nature of that special logic is. Maybe to exempt it from context-free abuse review, as gb_ said below?

Does it fix the LONG standing issue that Dr. Krawetz keeps discussing on his blog that makes it trivial to DOS an onion site? Description in the section about ‘Eddie’.

https://www.hackerfactor.com/blog/index.php?/archives/762-At...
The article was updated to include the two other authors names. There is an update at the end of the article mentioning this.
That's a valid point. Thanks for bringing that up.

So now I have a private channel to that address and I don't have to worry about the exit nodes (unlike when I use Tor for clearnet sites).

But now how do I know that I can trust the owner of that onion?
My understanding is that MariaDB is using an updated replication format which is not readable by Oracle MySQL or the Percona fork of MySQL. So you could not maintain a MySQL slave of a MariaDB instance, and would have to take downtime to switch from MariaDB to MySQL.

(This is only be true if you're using GTIDs in MariaDB, the old file:position format is still compatible. MariaDB does understand MySQL GTIDs, so replication from MySQL to MariaDB does work when using GTIDs in MySQL.)

Predict the stock market. There has to be alpha in abnormal increases in product-related queries.
>I'm sure you're correct, all stock picking is dangerous though. I'd assert that my style is the least dangerous.

Why? Seems to me that all stock picking has the exact same level of risk.
The difference is that with the on the fly cert, you blindly trust one piece of code, at one point in time, and when it did not lie to you then you will be safe from it later. A conventional cert owner on the other hand could theoretically turn on you any time (e.g. when ownership multiplies into pwnership) once "automatic trust" for the next binary is established.

I'd still prefer the latter, given reasonable standards in terms of key handling, but the one-time trust is not completely without merit. It would certainly be more reasonable though to just allow one-time blind trust without forcing the installer to create a certificate that may or may not be as private as advertised.
Sometimes; and tools like Ansible Container can help have the best of both worlds.

But for every time I see someone using actual configuration management and best practices for reproducible Docker architecture, I see a hundred times when there are brittle and convoluted shell scripts or worse, entire application definitions in a 500+ line Dockerfile (which is neither configuration management nor scripts. At least the scripts are somewhat more portable and maintainable!)
This would mean wasting fuel, no?
In the vein of Kumail's critique, if it's useful to anyone, I wrote some thoughts about software engineering and ethics from my own experiences:

A serial tech entrepreneur in Silicon Valley once asked me to design a “social stockade” for his financial services customers. It would lock people out of their social media accounts and tweet out/FB share to their friends when they hadn’t paid a loan. He pitched it to prospective employees as meaningful work that would reduce the cost of loans for the needy.

I was horrified that his product was being built and that many others would likely take the role I was turning down. And he was hardly the first to pitch his “innovation” as providing only good.

Every software engineer I’ve worked with has had a strong sense of personal values and ethics, but the organizations we work for can take actions that are at odds with these. I’d like to highlight a few of the key challenges you’ll face and provide feedback for living your personal values. Most importantly, it’s critical that you think about the impact of your work and consciously set your personal values in advance of inevitable future challenges.
