I worked for Unimation, the company that invented Robots. The 'research lab' consisted of myself and Ming. We were, I believe, the first people to ever connect a computer to a robot. It was a PDP-1103 (https://en.wikipedia.org/wiki/PDP-11#/media/File:DEC_LSI11-2...) connected to a 6-axis industrial robot (http://www.robothalloffame.org/inductees/03inductees/unimate...).

We built a board to talk to the robot by replacing the robot plated-wire memory (https://en.wikipedia.org/wiki/Plated_wire_memory) with our wires. We ran into two problems. The first was a hardware bug. We had a 'ground loop' (https://en.wikipedia.org/wiki/Ground_loop_(electricity)) when we connected the 5-volt DC computer buss to the 440-volt AC robot. The computer was unhappy.

The programming bug was more subtle. Ming's computer card required a 'trash read' (read-and-ignore-results) in order to initialize the card. So the first read of the robot position required 2 reads, the first result was ignored and the second result was used. Normally I wrote machine language using paper tape. But that week I got a BLISS language compiler (https://en.wikipedia.org/wiki/BLISS) from a programmer at CMU. It was a super-optimizing compiler. The machine language program worked. The BLISS language program did not. Ming finally convinced me that the BLISS program, despite what the source code said, was NOT issuing an inital double-read (using an oscilloscope on the data lines). The bug was that the BLISS compiler figured out that the first read results were never used and that it could optimize the first read away, no matter what the source code said. Props to the BLISS guys.
How often do planes actually crash? Is it often enough to get statisically significant data about survival rates in the event of an evacuation?

Also, evacuation after a crash is not the only safety issue - there is deep vein thrombosis, for example.

Nice strawman, but in reality you can punch back at someone who wants to fight or run away. When all you have is one planet and there exists a few cunning and belligerent actors with immense resources and oversized military budgets, you don't have the same options when you're cornered.
This information is freely available, e.g. on seatguru.
They just gave up, and that's the reason?

You're probably young, and have a wonderful support sysyem (these days, a rich, sympathetic father), but be careful about throwing around aspersions.

Life will throw you some real curves. It might get so ugly, you will look back upon your youth idealism and literally cry?
Focus on what you want, you are in control.

I'm not interested in what easily distracts you.
So the people that went through the Great Depression and WW2 and buried all that shit inside after WW2 ended so their children could live without that burden were selfish? I'd like to hear your explanation on that one!
I think this is a great idea! You should submit some feedback to Kayak to suggest it.
All the more reason to do research into making sure there isn't a safety issue here. Stats like this just make people and companies complacent until the next tragedy strikes.
no one ever denied the fact of internet censorship in China. the point is that the biggest impact of GFW is the block of sites like Google/fb/twitter and its largely for protectionism.

blocking WSJ is bad, really bad, but let's be honest, how many Chinese would be reading WSJ? 0.1%? Sure, that 0.1% still counts, they should be allowed to read WSJ or Reuters, but it is not remotely comparable to the impact of blocking, say, youtube. how many Chinese would be watching youtube? I'd argue hundreds of millions could be watching.

With all these numbers in mind, and the fact that there are highly popular replacement services in China for every single one of those blocked one like google/fb/twitter, you tell me what is the primary goal.

it is also worth pointing out that blocking WSJ/Reuters and similar web sites are bad decisions, but blocking Xinjiang/Tibet independence movement sites are totally different matter.
The parent comment is mostly correct, at least according to the Slate article here:

> You bought a TL-15 safe for your home?

Yes I did. It did not weigh hundreds of pounds. Its location was constrained a bit by where it could be secured to the structure but not unreasonably so. And it wasn't like I've got paintings or something in it, just stuff that if the house burned down I'd want to have survive and a few things I'd rather other folks not have (like passports).
Seems more like helicopter money, without the goverment middleman
If that's the case, then the burden of proof for copyright-based censorship is questionably low in this UK scheme.

I mean, mail.ru clearly has a primarily non-CP non-infringement purpose; banning it (is it actually banned?) should have been transparently disproportionate to anyone reviewing that claim.

There must be something we're missing. Not that I think the tin-foil-hat theories sound much more likely.
>>If not, it should be of global interest to crush the dictators

As a species, we have evolved institutions such as the UN to effectively convey and act upon those global interests in a civilised manner. This happened after humanity suffered the horrors of two world wars. If anyone, anywhere decides to wage a war supposedly to guard global interests, they should at least get a global consensus, no? That democracy that you speak of.

Because other wise self defence would be justified, honourable even. The problem with Iraq and Libya isn't what you described post-war, it is that they got invaded in the first place. A perfectly good country would turn into Iraq and Libya if you invaded and dismantled its government.
Thanks for honest counter arguments!

I agree with (1) from a long term perspective and think we should increase funding to green tech researchers. But I weigh political resistance to developing resources (ice breaking trade lanes, oil wealth, etc.) on the North American side of the Arctic ocean as benefiting Russia more than unquantifiable acceleration (due to more research funding) of the eventual long term, technology based decline of fossil fuels.

On (2) and (3) these are basically free market vs. government organized enterprise and left vs. right political arguments, so I'm not sure if I can rebut them articulately. And they probably come down to Putin's and Xi's personal opinions, not ours.

But if Xi wants to subsidize worldwide solar power production at the cost of China's other industries, I say go ahead and we'll probably still compete with private actors. They should lead some like us.

And again, I'm not saying there shouldn't be any US government organized enterprise in this field. For example I think the US, Russia, China, UK, and others could work together by laying a great circumnavigating high voltage DC cable for solar energy, on which ``the sun never sets''. But still the validity of (2) and (3) is definitely colored by political leanings.

> How could a library not excite you? :D

I'll go ahead and answer that for you: $80 a year for a service I have never used nor do I know anyone who has used in the past decade. It's just not a good value for money to me.
Totally.

I think airline travel provides one of the clearest examples of the big different between what people say they want (legroom, good quality food, friendly service), and what they will actually want / will pay for (cheap seats).

Let's not forget, premium economy, business class, first class, private jets are all available in this market for people that actually want large and comfortable seats and are willing to pay more for it.
In the SF main library, it's mostly a smell thing for me. I would feel the same as you if I didn't have to feel like I was reading a book in a sewer. I agree, I don't care about the socioeconomic status of the library patrons.
Sounds unfair and probably happened to other small businesses.

I'd love to read a blog post about your experience with amazon affiliates, and I also think it'll help with getting those cheques amazon owes you.

That means we have a model to start with. Chicken & egg.

I'm not going to lie, homeless people make me uneasy. I'm not rich, white, or privileged that I put myself on a pedestal; I'm simply aware that a great deal of homeless people are mentally ill, and that doesn't make me feel secure or comfortable.
People like you are exactly why I love HN - no matter the topic there is someone along with immense personal knowledge and a fascinating story. Thanks for sharing!
> The X11 system used to require knowledge of monitor characteristics in order to install it. So you had to know things about the clock rates, flyback time, etc. to use a monitor. There were many X11 threads about finding the settings for a new monitor since the manufacturers were not very forthcoming with them.

Oh boy, I remember those days playing around with xfconfig and hoping for the best.

When I got Slackware 2.0, my card was a Trident that could only do 640x480 by default, anything higher required playing with that configuration.

Generally, doing business of any kind requires a license. At small scale, the rules aren't enforced very much, but when you get big or someone doesn't like you, they are. Since everything you do can be interpreted as illegal in some way, there's no defense, and there's no recourse, since the courts aren't independent.

About embedding of workers: local employees who are party members will organize a party branch inside the company. The more powerful internal party members you have, the easier it will be to be given permission to do things, get licenses, etc, so they'll gain committee seats and power. So you end up with an internal organization with power in your company whose allegiances are to an outside agency.
Presenting unexpected futuristic solution to client
I'm in talks with a client who is asking me to build a software solution for his company. They have a preconceived idea of the software (that I'll build for them) which is very ancient way of doing things. But I have a far advanced solution that is being adopted around the world and it will change they way they work in very awesome way.

Trouble is, I think they'll be scared away from the new ideas and reject it altogether.

Question:
Have any of you ever been in to my situation? What did you do and what outcome did that bring?

Thanks in advance.

You can't copyright a softwarw API in the US because they are considered purely functional (in the mechanical sense). Take flathead screwdrivers as an example.

You can't copyright the dimensions of the blade head, since they're just the dimensions of the screw slot, and the only thing the copyright does is harm interoperability between screws and screwdrivers. You can copyright some other aspects of the screwdriver design, and if screwdrivers were a new thing, you could patent the idea of a screwdriver.

Index of element is greater than minus one is an odd way of thinking about whether an array contains an element.
The motivation for the Hessian is the same as for dividing by the second derivative. Suppose we want to solve f(x) = 0. Taylor expand f(x) around the current iterate (a)

f(x) =~ f(a) + f'(a)(x-a)

We want f(x) = 0 so,

0 = f(a) + f'(a)(x-a)

Multiply both sides by the inverse of f'(x):

0 = f'(a)^-1 f(a) + x-a

So:

x = a - f'(a)^-1 f(a)

This is the update equation for Newton's method where a is the current iterate and x is the next iterate.

If f is a multi dimensional function f : R^n -> R^n then the derivative f'(a) is the Jacobian, and inversion becomes matrix inversion.

When we use Newton's method for minimisation of a function g we solve g'(x) = 0, so we pick f(x) = g'(x). Since the formula above contains f' we get a second derivative. The second derivative in multiple dimensions is the hessian.
This is a real problem, and one that is difficult to address. San Jose's MLK Library (also shared with San Jose State University) is the day time destination for much of the city's homeless population. Who can blame them -- it's a safe cool place to stay and sleep during the day.

Unfortunately, this limits the space that is available for people to work and study. There have also been two suicides in the past year (people jumping from the 7th floor balcony into the central atrium -- it's now being walled off to prevent this).
That sounds more like a mental health issue though. I just hope the US government puts in single payer healthcare so resources can be allocated to deal with it properly.
My grandmother worked in the oil industry around that time. I think she was at Gulf in the 60's / 70's before moving on to Shell and retiring in the later 80's.

When I was too young and unknowing she would lecture me about her work in Fortran and other languages in her systems analysis work. Unfortunately she lost her mind and passed away before I had the chance to question her in my own better state about her work.

Ask HN: Best way to turn plain text tab-indented list into JSON?
I have a list of unknown depth in plain text, where the levels are represented by tabs.

Something like this:

item 1
item 1.1
item 1.2
item 2
item 2.1
item 2.2
item 2.2.1
item 2.2.2
item 3

What is the most efficient way to turn this into a JSON array (ideally in JavaScript)?

Of course, I could go line by line, have a currIndentation variable and create an array, but I'm wondering if there is a better way.
The market is not "too large to leave". The company is making a choice to stay there because to them profit is more important than ethical considerations.

At the same time, the fact that the West generally doesn't care about ethics shows that the West is not necessarily a good model to follow. Maybe China has a better alternative.

I'm in the Canadian Maritimes about 1,000km (400 miles) north east of NY city. Winters here Dec/Jan/Feb/Mar can easily be a static -20C (-4F) my old Dodge diesel truck has no problems starting, I used to use a grill blocker and a block heater but really it isn't needed just use thinner motor oil for the winter. And the ability to travel 1,000km (621m) per 100 liter (26.4US gal.) tank was nice for a large truck the efficiency of diesel is far beyond gasoline engines.

I'd love a small diesel or electric or diesel/electric 4x4 like a Jeep or a four door 4x4 truck.

I'd take that electric truck though my love of diesel was due to its efficiency and torque now electric vehicles getting common that's a good replacement. Although I worry about going through deep water with a giant battery! In the springtime I've been through water 30cm deep (12") even in the middle of my small town.
Rules. No sleeping. No drug use. No bathing in the restrooms. No shitting on anything. No violent or threatening behavior. Period.

Then enforce those rules. One violation, and you're out. Two, and you're out for good.

Librarians know who the troublemakers are. They just have no power to do anything about them. It's not illegal to be homeless, but that doesn't mean you should be allowed to do violent, illegal or disgusting things without consequence.
I would really like to see a study of the economics of the smaller legroom.

My napkin math tells me if you remove two rows of seats from an all-economy 737, every remaining seat would get an extra 2.5-3 inches of legroom, which is significant.

I wonder how much revenue would this change cost to a major airline.

Looks cool!

I don't do much Python anymore, but I do use a tool like this for Javascript called Prettier (https://github.com/prettier/prettier). I'm not sure if Prefactor is inspired at all by Prettier, but it would be a good source for ideas as Prettier is an absolute game changer for Javascript programmers and makes programming a whole lot more efficient (and fun!). I hope Prefactor (or something like it) could do the same for Python.
Wanted to make a chatbot a while ago to allow the support guys to unlock AD accounts from our chat system. This sounds like it could be useful!

The point is to make it universally available, like the ingredients list on food packages, not just "freely available."
I'm impressed by the even handedness of the article.

Normally, I wouldn't even think about using a language developed and championed by a litle Czech company, however, JetBrain's tooling is incredible and I gladly give them money every month for R#.

On the other hand, usually I would think that the language being endorsed by a major company for their platform was a big plus, but the way that Google drops products and initiatives, their support means little.

So yeah, I trust JetBrains a lot more than I trust Google and if I ever decide to bite the bullet and start developing for Android, Kotlin will be my first choice.

> Mostly, performance is an issue with large apps and their rspec run times

I hear you! I hate long test suit runtimes, and they are easily grown. I made a gem to address this, by running your test suite across a cluster of cloud VM's and reduce test times from 30 minutes to 30 seconds. http://github.com/meesterdude/cloudspeq

> but that's where the "convention over explicit configuration" stuff becomes a hindrance rather than a help

I feel It just gets you going - you have a foundation you can run with - and one that other devs will know "out of the box", which means onboard is easier/faster. But it's never meant it's not configurable. You'll still need to cache, to adjust web servers and background jobs and all of course. But rails makes it possible, easy (and fun!) for one person to do all that.

> Our big old Rails monolith (started on Rails 2, currently on 4.2, and hopefully on 5.x in a few months) has carried us to about $500mil projected revenue this year.

Dayum! Well done! Do you know how many requests a second you serve and the avg. response time?

> Could other stacks have done the job better?

I think so long as you haven't been severely bitten by scaling or performance issues; the product itself is what matters so long as the technology can deliver on it. Clearly you're doing pretty well regardless! Proof is in the pudding.
I go to the SF library frequently and it is a gorgeous library, but it is absolutely full of homeless. I have seen needles on multiple occasions, almost always you will people hear screaming obscenities or just gibberish, and you guaranteed will at least smell some pretty nasty stuff on any trip in there.

A couple days ago one of them threw themselves from the 5th story and landed in the atrium. He could very easily have killed someone in addition to himself. I have trouble rationalizing this romantic view of the homeless as these poor downtrodden, down on their luck people who just need a hand up, with the realities I see everyday of mentally ill, dangerous, and completely uncontrollable people. They definitely are not there to read. A few have developed the skill set necessary to direct the free access computers to porn sites.

That being said I agree that homeless is not effective as a blanket term to describe anyone without a home, huge difference between someone living out of their car and showering at the gym, and a schizophrenic who hasn't bathed in 6 months.
Many think of Southwest as in the same league as Frontier and Spirit, in fact. It’s a budget airline which happens to resonate with some non-budget-minded flyers, proving that you can make a budget airline half decent more than anything.
TBH that's not how valuations work, simce projections higher than current sales are not reliable (unless there are special circumstances).

you have any questions on how an acquisition for your plugins would work?
Sure, the US and Russia should go first in ridding themselves of nuclear weapons since they seem to have the most. Then we can really talk about non-nuclear proliferation. There's really no reason anyone should have these immensely dangerous weapons, other than for MAD. But should these nuclear-armed-to-the-teeth states push others around while largely keeping their own nukes, what kind of message does that send?
My impression is that it can be installed on any machine (even your own workstation) so long as it can reach your DC.
I think I've not visited a public library since I first used Amazon in 2001.

While studying I've used the university ones a few times, but I've also always preferred to buy my books if they were important enough to be read thoroughly and repeatedly.

On the one hand I'm kinda sad about this, on the other hand I like to own and revisit the books I read.
Wow, not the same thing at all as the airline disclosing it up front. I should not have to go looking at third party sites for information like that.
That's not too far off base - just that the AR-15 came first, followed by the M16 and later M4 variants on the military side, and any number of manufacturers' and homebrewers' variants on the civilian side.
I love the library and will frequently check out books. I much prefer physical books to digital books. There's something satisfying about holding a book, opening up the cover, flipping the page, etc.

A few areas for improvement:

- Most of the libraries I frequent have very slow wifi, but this may be on purpose.

- Most digital library catalogs have terrible UIs (broken back buttons, poor search results, etc.) They work, but they're not fun to use.
How available is knowledge if nobody knows they can attain it? This is the first I've heard of seatguru, and given the post you responded to, I'd hazard I'm not the only one.
In my experience, if you don't travel enough to have status, Southwest is one of the better companies for not being treated like a pleb and getting nickel and dimed at every turn. Furthermore, many people find no assigned seats to be a plus.
So a three year old finding an unanticipated way to slip out of its chair is evidence that it is smart, but a neural net finding an unanticipated common pattern to all school bus images in its training set is evidence to the contrary?
