The scientists quoted in this article may be right but they seem to be responding in an overly aggressive manner against a perceived outsider to their field.

> “It is complete bull, and you can quote me,” says Richard Connor

How do you really feel?

> “The Ryabov paper effectively ignores most of what is currently known about the properties of dolphin clicks, how to measure them correctly, and how they are used by animals in various contexts, and instead lays out the author's own ideas for how dolphin communication might work by weaving together some simple observations with various disconnected notions of acoustics, cognition, and language research,” says Lammers.

I guess thinking out of the box is discouraged.

> “Many, many animals across the animal kingdom will avoid signal masking and thus time their vocalizations accordingly...This by no means should be compared to human language” says Stephanie King

What I'm not even allowed to make comparisons.
Tl;dr: Even startupy people need to behave like adults.
Passenger planes are much more fuel efficient per passenger-mile than single-occupancy cars.

Where did you get this idea from? Flying being more efficient than rolling doesn't fit with what little physics I know.

Do you have a better source than:

I would be genuinely interested if you have other references to transport fuel efficiency.
I'm Scottish and thus was brought up on entirely cooked food.

Fish was bread-crumbed or battered, and was invariably cod. And deep fried. It was always filleted, no bones, and was either a fully filleted piece of quality fish, or fish fingers.

In fact I can't remember a time where I had to eat any kind of meat which was raw. Also, we didn't really eat any kind of shellfish - or at least, I had an aversion to shellfish ever since I was given boiled winkles (sea snails) at a young age - around 4 or 5. So I got fussy with my food - no shellfish, no "sea bugs" - prawns, lobster, whatever wasn't filleted and bread-crumbed or battered fish.

You can imagine the comedy after I married a Japanese woman. The Japanese love raw fish. And me being set in my ways, and 100% stubborn, usually refused to eat raw fish. The only time I've eaten raw fish was after a good few doses of sake, when my inhibitions were lowered. Otherwise, it's a case of "Nope!"

I also decided that moving to Japan was a Good Idea (we had lived in London for 12 years, which as a Scotsman I hated vehemently), and ripped our family (by then we had a son) out to Japan, where we lived and I worked for 6 years - in Koriyama city, Fukushima prefecture, until the magnitude 9 earthquake and subsequent Drama made for a less than perfect life and which was the trigger for me to drag my family over to my native Scotland where we now live, and where the ground is reassuringly Very Ancient and Doesn't Wobble So Much.

So, living in Japan had plenty of comedy. There were the inevitable Family Get-Togethers, and in Japan this invariably involves copious amounts of raw fish, which, if you're me, is "Totally Awesome </sarc>". It means there's 15 plates filled with raw fish sushi and sashimi, and then one plate filled with salads and chicken kari-agi (chicken nuggets for the uninitiated ;) ).

Yep - pretty stubborn and fussy eater all right. The point of this monologue? My motto is "I eat to live, not live to eat".
I use a pretty vanilla Emacs. The only customizations I do are:

- removing clutter (zapping toolbars, splash screens and the ilk)

- making very small tweaks to keyboard bindings so that it works more like Epsilon

I don't think that any of the Emacs improvements made over the last decade or more have done anything to my quality of life in Emacs. Rather, each release is more "what do I have to turn off this time?"

Fortunately, getting to bare-bones Emacs is not hard; with commercial editors it's often much harder to undo the damage of gratuitous "marketing checkbox" features. [I'm looking at you, Visual Studio 2013...]
Maybe I should have stayed in self-driving. But in 2006, the field was dead, and I got into other things.
The headline and one line summary at the top were probably written by an editor, not the author. The editor probably skimmed over the piece, saw the line "the Japanese government projects that 30 to 50 people will be poisoned each year", and didn't realize that most poisoning victims recover. Or didn't care.
Doesn't apply to obvious wins such as variable font sizes or high DPI. Those items are necessarily high priority, because of their low hanging fruit nature.

Or, they just get their priorities wrong, meaning, they're being stupid. Not a safe assumption in my opinion.
Portland's homeless problem is supposedly vastly, vastly worse than San Francisco.

What does it mean to "take care of" our homeless? House them? Who is willing to pay $3k/mo rent per homeless person?

In a third world nation, the "homeless" in San Francisco would be allowed to build a shantytown and would not be considered homeless. I'm not trying to minimize the real issues of poverty, but you can't avoid the fact that part of the problem is that regulation/civilization/whatever you want to call it has disallowed poor housing.
That's not the point of the OP's question. It just stinks of plain greed. Typical banker attitude from a lot of people here.
If you're a user then it doesn't matter what distro you use, they're all fine.

Not at all true. Lots of people prefer Mint, for instance. I'm one, and one reason is for me the Ubuntu gui is just awful. Or what if you need really high security?

One of the main things that scares people off of Linux is the hundreds of distributions. Telling them it doesn't matter which one they pick isn't going to help with this.
San Francisco spends $241 million a year[1] on the homeless. Perhaps what it says about America is that you can't solve these kinds of problems by throwing more and more money at them, but that won't keep politicians from trying.

GnuWin32 complements emacs quite nicely. (It is an extensive set of natively built GNU utilities - no emulation is required.)
Will ethics (e.g., the collection and storage of personal information, or professional responsibilities in regulated industries) be given any treatment?
If x.Foo() and y.Foo() do different things and return different values, clearly x != y, and golang needs some kind of SQL-style is-null check rather than using equality to check for null.

But dynamic dispatch on "what type of object do I not have?" is still a damn weird thing to want.
It boggles the mind to hear 10+ million civilian deaths and wartime atrocities in Asia described as being "merely one perspective".

One can only assume that this individual believes Germany's concentration camps and what occurred therein were just "cultural relativism" and "propaganda" too and that Germany was "doing what it felt was necessary to protect itself".
I'm sorry to say you're in a minority. At least for the past 5 years commercial libraries assume you are running RHEL (usually one major release behind) or Ubuntu (LTS). It used to be Debian before that. If you're not you are going to have a bad time.

Of course if you're determined with a lot of work you can recreate the environment by compiling the exact versions of tools and libraries required (if you're lucky the library will specify that, otherwise you'll have to divine it through magic). But when you're doing this for a living you probably have better things to do.

It's a lot easier to use the distro that already has the correct deps and just get a newer version of a tool that you want to use if you really think that the one in the distro repo is too stable for you. So much less work.
ISIS got started from funding rebels against Assad...
You have the power to do the same thing, far less effectively (because less money and less knowledge of AdWords), for as long as Google choose to permit you to. That's not the same power as Google have at all.
I could only read a third of the article before starting to crinch too much. If this was on purpose and I missed the same conclusion I am presenting here, sorry.

The article sounds like "this of course is the smart way, make money first, worry about details later". But if you think about it this is very, very wrong. First, if any system will fail drastically at some point. You wait long enough and something unexpected happens. Second, if this consistency tolerance becomes widely known people will try, and at some point succeed, to cheat the system big time.

If any of these two scenarios happens, the whole system breaks. And then, what do you do? You can only get so many bail outs from the tax payers. The smart way, of course, is to not be too greedy and stick close to a relatively consistent scenario.
Did you ever read Jamie Zawinski's blog about setting up DNA Lounge in SOMA? Neighbors absolutely do care about this stuff, and will make enormous pests of themselves.

For that matter, are you a member of any local social network thingies? I've on NextDoor, whatever that is, for the last few weeks, and I'm surprised to discover that every local business I knew about (and several that I've only now become aware of) are defined primarily by the random, petty (to me) seeming complaints they generate from the neighborhood.

I wouldn't be too quick to jump to the conclusion that complaints like these are "enemy action".
Having lived in chicago, DC, San Diego, and visited NY, philly, LA, honolulu and baltimore, extensively, and volunteered among the homeless in SF, SD, DC, and Fargo - SF is much worse than the rest of the country.... Except maybe Baltimore. I think the US had a long tradition of taking care of the downtrodden outside of state-run institutions. This tradition was slowly dismantled starting at the beginning of the progressive movement (1920s-1930s through FDR) in favor of having the state run things. The net result now is that the state runs things poorly, and people now think that there is no longer any need for private charitable action, because government will deal with it.
With Twilio that should actually be possible.
One has debugging symbols and the other was compiled with -O2 optimizations enabled.
At the time, the ADA was harsh. He went to a lawyer when then sent a demand letter. This person was what some would call a 'professional plaintiff'. Laws in recent years have made that sort of thing more difficult, but the ADA still needs to be respected if you want to avoid headaches. Don't interview people in an non-accessible location.

But part of me does side with the guy. The startup wasn't wheelchair accessible. And they were small enough that making it accessible would have been very costly. Even if he had made it to the interview there was a good chance they might have passed him over because of his chair. That's the sort of discrimination that the ADA was meant to address. The startup should never have setup at that location.

Frankly, they had so many people crammed in that they were probably in violation of the fire code, another law that they don't teach you about at coding bootcamps.
Could you go into a little more detail here? Thanks!
I'm not sure how wise that is. It doesn't exactly lead to readable scripts. Zsh has had the equivalent feature with the syntax ${(operator)parameter) for over two decades so plenty of time for more operators to be added. It is very powerful but worse than perl for code that looks like line noise.
Maybe it's a simple way of saying that the OP is not looking at it the right way? Sheesh! If you're just motivated by money, you're not going to go anywhere in this industry. I've met consultants who increase their fees overnight in the industry and piss of their existing customers. You don't win business by putting your finances first!
There was a choice to fund education for families and former patients, and attempt a transition to outpatient care. Dumping them on the streets and into prisons most definitely was a choice.
Easiest way to handle this is invite the local alderman over to lunch and contribute a few hundred dollars to his campaign.

Also invite the cops in. If you give the impression that you're connected, these things go away. Plus, a few hundred bucks means your phone call gets picked up.
I wish there were more info about this computer training to minimize cognitive bias. Wouldn't mind trying that out.

The distinction between rationality and intelligence (I usually think about it as rationality and logic) is an important one that is rarely made. Economists especially do a bad job of this, despite being the sort of people who should know better. Thanks to cognitive biases, limited information, and costs associated with getting past those two hurdles, people are rarely logical. But we are typically rational; we make the best decision available given our beliefs, evolved instincts, limited available information, etc. That can result in illogical behavior, but hardly unpredictable/erratic behavior. Understanding that people are maximizing utility based on a function that includes lots of tricky psychological factors--not just pure logic--is helpful in empathizing with others.
The USA is a lot more homogeneous than it is diverse.

The comparisons the author makes are on a scale much larger than the diversity of the USA.

If you cannot see this I cannot work out how to tell you, except perhaps to suggest that you and live and work on the other side of the world.
Bear in mind, when you're looking at making a commercial product, you look at cost. Presumably, that's why most companies have ruled out Google's sensor setup, which costs more than my house. As costs drop, sensors will probably be added or improved, and you'll see more companies integrate those features.

Google's program is a tech demo for PR purposes. Everyone else is trying to actually put systems in cars.
Would love to see some real highres screenshots. Even if the real world is lower res, to get an idea of the quality. I am still annoyed that you cant test the HoloLens on Microsoft stores.

I would get one of this instead of buying several monitors.
Ask HN: Is it real to get investment from CIA (In-Q-Tel)?
First of all, don't understand me wrong. We are a small team that have some kind of communication solutions that is popular in Iran, Iraq, Saudi Arabia etc. We can't read, of course, their communications, but it feels that it can be good to have such project in CIA invest fund. What if we will be able to save lives together? Is it real?

We are not US citizens, but we are from countries that are not that democratic and many clever people will be happy to leave and to work for a country that much much better developed in this field.

If you have some clue how to make it work and don't want to share it here you can write me to hanako@protonmail.com.
Irritating use of "zero" instead of "no"
It'll be a pick and choose situation. The UK does not care at all for ideas like freedom of expression. An example is the fact that it is illegal to draw or posses or distribute drawings depicting fictitious children engaged in sexual situations. This isn't an old law that's just a relic of history that's been forgotten to be erased, it's a relatively new one.

With the kind of attitude this displays, I have a bad feeling about the "Bill of Rights" that the government has promised to create.
There's overly complex regulation, and then there's "this type of business is required to have an air filtration system and yours has been operating without one for months".

My brother just opened a coffee roaster and cafe in suburban Chicago. It's just him, my sister in law, and a couple friends, none of them with any hospitality experience. There were a lot of regulations, and they had to go several rounds with the city during their build-out. But they got through it.

The weird thing about the comment upthread is that they were "forced to install" a filtration system. How did that get past inspection? The dumb little coffee shop --- no food, no cooking smells --- had to have one just to open up.
Msys2 by design restricts the available packages to those useful for compiling software for Windows. The emacs package is in their separate mingw repository, which means the produced binary is a Windows program and does not understand the posix environment at all (i.e. no /proc/, /dev/ etc).

Cygwin is an OS that runs on top of windows - all cygwin programs are windows programs but not all windows programs are cygwin programs. The emacs package for cygwin can fopen() /proc/ and /dev/, use the linux socket API, and in general follow the linux makefile more closely.
The proposed distro (Debian) was spot on for me. You could probably split the questionnaire between people who want to try linux for the first time, and people who want to try a new distro.
(TL;DR - this is a concept that computer science borrowed from math)

In math (say abstract algebra / group theory), the operations on your database form a group under composition. Given two operations f,g (say f is "subtract $10" and g is "subtract $20"), the composition of those operations could be written "f•g" (depending on notation this can mean g is done first or f is done first, typically the former convention is used).

(So, instead of numbers and plus (+) in your example, we're using functions and composition (•) as our group.)

This group, of operations under composition, is said to be commutative if f•g = g•f for all f and g. (That is for all combinations of your possible operations.)

For addition/subtraction operations you're good to go.

If you can consider operations on a hash table being things like 'set a value of 10 for key "a"' the order that the operations are executed in do matter, and the group of those operations, under composition, is not commutative.

The subject of CRDT's in computer science is an attempt to create data types whose operations are commutative.

One reason to want do deal with commutative operations is that you don't have to figure out the order in which the operations officially occurred.
But that't the whole point - Xi'an foods started as exactly the kind of a no-name, hole-in-the-wall like you describe.

How'd they get to where they are now? Because they get food, they get what what people really want, and they found a culinary niche that until that point had been widely ignored.

That's how they made their "brand".
the security guard sounds overeager ("Everyone in there makes over $1 million" - really?).

Not having been to skid row, but if it's like the tenderloin (and I've heard it's worse) you know the streets are totally overrun with vice.

The notion that private corporations enforce social control is not novel. What's new is this pattern of tech companies going into sketchy neighborhoods and 'cleaning them up'. In San Francisco Twitter got a tax break for 'revitalizing' the area. Part of the tactic is patrols by 'Business Improvement District' officers.

I think Google must have known what they were getting themselves into. Probably got a tax break for their 'sanitizing' effect. This being said, it's disingenuous for them to not acknowledge the problem and point their 'brilliant minds' to research being done.

There's a need for more evidence-based policy on homelessness. Services and transitional housing are good ideas. For Google to quarantine a two-block radius doesn't help solve the larger issue at all.

At the same time, the issues of skid row are not just 'lack of sidewalk space for tents'. The concept of a "sanctuary encampment" is developing, but I'm not sure that designating the neighborhood 'tent-friendly' is productive for anyone considering the amount of drugs there.

It's also not really fair that low-income apartment renters need to live in such a chaotic area in order to afford a bed.

Kicking homeless people out of a peaceful off-the-grid settlement might seem cruel, but I have slightly less sympathy for their plight at the urban core. Making these neighborhoods sanctuaries is not a solution unless the broader support network is there (stuff like mental health, finance, and drug support), which it's not.

For Google to kick out these people may be slightly counterproductive to society's larger homeless issue, but not dramatically so.
Sandwich boards are terrible. They are very ugly and very annoying to walk around, particularly for the visually impaired.
Under those conditions, everyone would pick the utilitarian solution. There lies the problem IMO: psychologists carrying out experiments about "morality" when they have absolutely no theory of morality. Lacking this, they're left with "two of the same bad thing is worse than one of that exact same bad thing," and limit themselves to problems of relative morality, ignoring the fact that you can't do the same bad thing twice.

Ignoring is a mild way to put it, actually, because all of their experiments involve doing multiple additions and subtractions and substitutions. For them, morality is definitely a real number.

I think the complexity of these hypotheticals is entirely a result of a need for varied responses. The real answer is that there's not enough information given to make a determination. In the case of your hypothetical, there's clearly enough information (because one of the premises is that you have all possible information.) The question for the subject becomes easier, and the tough question becomes "Why is this horrible magical creature doing this, and how can we make it stop?"
I ran into this when working on some software that put user comments in <p> tags. I added some allowed markup that came out as <div> tags for a collapsible section. It didn't strike me as a particularly insane feature, but I about lost my mind trying to figure out why the <div> tags appeared to negate the <p> tag styling for all of the text after it.
such an awesome story!
What is the most interesting thing live streaming right now?
That's a wonderful point. You still get to experience the culture -- what is popular and what makes a place unique, and what works well in that place.

Often when I travel, I take note of things I like and wish to buy, but remind myself not to make an impulse purchase; I can always buy it once I get home, if I still want it -- and not have to carry it with me for the next 2 weeks!

I think perhaps that very thought process is the reason I began thinking of travel as less "special".
I think it's not necessarily that the money is being spent (in general) but rather the money is being spent in the wrong way. For example, we've spent untold billions of dollars on the "war on drugs" since it started with Nixon, but it's been mostly spent on incarceration rather than rehabilitation; if that money had been spent on safe needle spaces, mental health clinics, and easier access to alternatives for drugs such as heroin like methadone, the problem may not be solved but would be in a better place.

Homelessness would also be in a better place if the money was spent better. Better shelters, better services similar to those I mentioned above, and better information about each person like the article mentions would substantially make the issue better.

But those things aren't as easy to justify as the alternative. In the case of incarceration, because the effects are effectively immediate, it feels easier to put someone away for 10-20-life rather than giving them a better life.
