I believe GP was referring to delta as in mathematics, which refers to difference and not necessarily change. So the delta between +7km/s and -7km/s is 14km/s.

Apply HN: Automate the $450B bookkeeping and accounting industry
Business owners know this question all too well: 'what was this transaction for?'

The problem is that, we can hardly remember what we ate for dinner yesterday, let alone what we spent money on from a month ago...

It's annoying and it's a gigantic waste of time; and by gigantic I'm talking $450 Billion dollars spent each year employeeing bookkeepers in just the US.

Fortunately 80% of all bookkeeping work for basically every business imaginable is repeat, month after month. So guess what, that means it can be automated and systematized using business rules.

We've developed a app called AutoKept as our 'level 1' product where business owners can 'Talk' transaction descriptions right into their accounting software. This has generated us over $10,000 MRR since November of 2015.

Now we're releasing 'level 2' which will bring a whole new realm of workflow management around documentation and transactional data / tasks to the business client and accounting firm. All we have to do now is 'watch' how the work is being done by the accounts for their clients and step-by-step automate their repeat entries for them.

We could be on track to automating 50%+ of this industry, very soon. This is fantastic news for all buiessnesses that are involved since it will save them a ton of money by just letting the machines do the work, and for the bookkeepers, well like all other automation technology - let's get on with it and have the humans doing more productive things with their lives.
>I maybe wrong, but a "tech worker" to me is not someone who works for a tech company but rather is one who creating the tech.

You're wrong, if you work at a tech company you're a tech worker. Programmers like to think they're special, but you're the help just like the sales people, support people etc
pledge seems like it could also help in another scenario that the recent npm issues should make us worry about.

When using a third party library, it should be possible to have more faith that it's not doing something unexpected. So not only can it protect you against ingress attacks, but also potentially against malicious code you might accidentally include in your software.

(I'm assuming of course that the third party library can't reset the pledge)
One easy solution is to have a server side application that just serves the view layer. That bit can be JavaScript, then your API can be whatever language you want.
The program being voluntary does not make it un-creepy to use devices which track what an employee is doing at home.

Many people use non-free software and devices which can (and often do) spy on them. It's voluntary, but the spying is still creepy.

My take, is that this primarily attempts to address one of the key criticisms of use cases - the granularity issue. Use cases are often too broadly written initially. When examined closely, one discovers that that the use case presented really needs to be broken down into many more detailed (and changed) cases.

The introduction of "slices" appears to acknowledge that. The problem is that like functional decomposition in structured programming, constant re-arrangement of the functional "tree" representing the problem will likely result.
Higher quality road surfaces have a lot to do with it.

Hi! I have actually spoken to a number of different people regarding this and a vast majority liked and would use something like this. I do understand where your question is coming from so I am going to add some context to their responses.

1.) Some people said it would be awesome to use when they travel to meet up with people at conventions and or other tourist that are also traveling to go site-seeing or enjoy company together.

2.) Another person said, because she is 'single' and most of her friends are in a relationship it is often bothersome for her to go on third wheel or fifth wheel outings and she doesn't really have any friends that are not in a relationship in her circle.

3.) An answer we heard often was from people that just moved to a new place and/or got a new job they said it would be an great tool for them to get to meet people and or enjoy company during their lunch breaks.

Right now many of them did say that they were using other social apps to meet people mainly Tinder. At the same time they all felt that Tinder was not made for this purpose but they did not know of a better tool.
Git-standup: what you committed yesterday for daily
> I feel like in these scenarios he's incentivized to get outlandish PR for his book, so some of the things I'd take with a grain of salt--sentences like, "The offices bear a striking resemblance to the Montessori preschool that my kids attended: lots of bright basic colors, plenty of toys, and a nap room with a hammock and soothing palm tree murals on the wall." But there is probably a lot truth to his story as well.

Surely this is clearly an observation? When I read this I read it as opinion, and a personal observation he had - after all, it speaks of his kids' preschool and it is a judgement he makes.

This sort of comment is done in long-form journalism all the time. The fact you spotted it as subjective commentary almost immediately means it is commentary!

The book he wrote is a commentary on his personal experiences with HubSpot, interspersed with his views. I honestly don't see where the issue is, it's still factual but as with any article or book like this the author is giving his considered view on the material he is writing about. It's perfectly reasonable to disagree, of course, but is it really to get PR for his book?
an autonomous robot can go swap out it's own batteries, or go charge itself. if it can operate for 24 hours a day, losing ~5% of that time for battery swapping is not that significant.

> Imagine if you used your car insurance to pay for gas. That would be ludicrous.

That's not ludicrous enough for me. Can the insurance be provided through my employer so that I'll need different insurance to pay for my gas if I switch jobs?
1) We do specifically address the power imbalance between employers and employees. Because managers typically have more power in the relationship, it is critical that managers take the initiative to prove themselves trustworthy. Now that talent mobility has increased so much, employers who continue to treat employees as disposable are going to have a hard time attracting the best talent.

This doesn't mean that all companies will behave in an enlightened way, and there are cases where employees who lack specialized and valuable skills will still be treated badly.

2) There are also corporate cultures that place such high demands that they have negative impacts on employees' health and happiness. The purpose of our book isn't to defend all corporate employers! Its purpose is to lay out a plan for how corporate employers who believe in our ideas can build stronger, more mutually beneficial relationships with employees.

3) Losing a job can be devastating, both to your financial life, and to your health and happiness. It doesn't help that the social safety net in the United States is stingy and inconsistent. But unless you prohibit employers from laying off employees, I really think this is more a matter of government policy. And preventing employers from firing people always has unintended consequences, such as discouraging any hiring, and encouraging black market, off-the-books work.

Have you actually read our book, or even one of our many articles? I feel like you're judging me based on Dan Lyons' editorial, which as I've already pointed out, quotes exactly 6 words out of the entire book.

Broadly speaking, capitalism works because it is a voluntary exchange mechanism. It doesn't work perfectly, which is why we should strive for things like educational reform (to give everyone a chance to get a good education). But no system does.
Let me work in news industry for a while and write about how terrible the management is, how honest journalism is rejected and shitty PR articles are the way to go, the sheer amount of pointless meetings and asshole co-workers.

I am not sure if you would be happy to work in such a workplace and that describes most of the corporate culture. People are fond of bashing startups for what they are while conveniently ignoring how much more work they get done while keeping everyone happy. Don't like it? Get a job at IBM.
If that happens it will be a fight.
Are you really contributing to the conversation when you leave out important stuff (like everything BO is working on), and then, when challenged, call something that's scheduled to be flight qualified in 2017 "far off future stuff"?

In my limited experience, OEM is horrible, unless it is the only option.
This doesn't have much in the way of interesting details, you need to go to the paper for that.

The armour is a composite sandwich, with boron carbide on the front face (a hard ceramic), followed by the metal foam, and either aluminium or kevlar on the rear face.

The boron carbide layer blunts the bullet and distributes the compressive stress over a large area of the metal foam. The metal foam is made of 2mm-diameter hollow steel spheres in a stainless steel matrix (created using powder metallurgy). The metal foam deforms plastically under the compressive stress, absorbing the kinetic energy of the projectile (i.e. the spheres get crushed). The backplate provides tensile strength and stops the foam from tearing apart due to residual tensile stresses.
Sales opportunity.
>Dan Lyons idealises a world in which people worked their whole career for one company, had a slow progression of minor promotions and pay rises & retired to a gold watch they took to Florida. That reality makes me personally want to buy a chair, some rope and to Google how to tie a noose, but my view is certainly NOT universal, and I need to accept and recognise that.

I think the angle you're missing on this sort of job is that it's perfect for someone for whom their job is not their self-identity. In the tech realm today, a lot of people really tie their identity to their work, and for them, this sort of job is really bad. However, there are lots of people for whom a job is just a paycheck, and their passion lies elsewhere. Often that passion is in an area where significant money just cannot be made (family is the most obvious one, but there are others.) I've worked in public service in the past, and you see lots of people that have been working the same job for 10, 20, or even 30 years. When you talk to them, it's clear that the job is fine, and they enjoy it, but what they really care about is their kids, or the dogs they walk at the local shelter, or whatever their passion is.
if you have something that interrupts the wave it blocks the whole wave. that's why the gauss on the microwave front door works yet you can see through it, because microwaves (the actual waves) are in the order of centimetres wide.
I've wondered why rail isn't automated. Trains have accidents but they have a (mostly) 1D, simple existence. Cars and trucks are mostly 2D, with many more variables and one-off situations. Fix rail accidents and you get a huge win.
I understand that it's voluntary, but the company has literally followed its employee into the bedroom, via remote sensor.

It's easy to see how that might be unsettling to some, even to suggest, "hey, wear this leash on your off hours, and I'll give you extra money."

I didn't criticize Dan's book, or say that his statements about HubSpot were inaccurate. (Note that I'm not saying they're accurate either; I haven't worked there!) What I did do was to point out that his op ed does not accurately reflect what I wrote on my book. I don't believe this constitutes mischaracterization on my part.

HubSpot fired two senior managers because they tried (foolishly) to use deception to obtain copies of Dan Lyons' book before it came out. You seem to be implying that our book promotes such unethical behavior. Again, I'm unconvinced that describing a program for allowing employees to expense networking lunches constitutes encouraging an abusive culture.
A Wild Way to Save the Planet
Just like pizza tastes better when you made it yourself, it is sweeter when you were able to code your own working coupon generator.
Programmers are still operating under the delusion that they are so much better (or worse) than the guy working next to them. It is this kind of egotistical thinking that probably gets in the way of them unionizing. You want to give a large caliber a-hole like Bezos the finger while working in his own company? It takes balls to do that - stage a walk out and strike. It takes camaraderie, intimacy and loyalty to a cause (or a person) that supersedes the workplace, an all in support to that cause by engineers/programmers alike.

For as long as the pissing contests over languages, productivity, hubris, etc continues among intelligent people like programmers, their Jimmy Hoffa won't be born and their cause will lie with the company's objectives.

In a nutshell, programmers -deserve- the Bezos and Hastings of this world. Keep thinking you are God's gift to programming and insure the demise of your own fellow programmers.

I have zero sympathy toward programmers (having been one for 17+ years now) - not because I don't love the profession or the contribution we make, but because of the infinitely immature attitude and disunion that exists among engineers.

If there's one thing that has motivated me to think of doing something else, it's that...
You are not alone in thinking that only copyleft licenses are free. I think people get this association from GPL = free = Stallman = copyleft, since rms does keep talking about all of those things, so that's what people think he is saying (or they get it second-hand from people talking about what rms said). However, rms has never said that non-copyleft licenses are not free. He does call them weak or pushover licenses, though, but he doesn't think they're wrong.
Merchants typically have margins of at least 35%, so they may make smaller profits, but probably not negative. It may be a discount, though the value of GD is not measured solely in it's USD value.
I'm not an expert, but after some Googling, I think the bullet they're using there consists of a steel core inside a lead envelope inside a copper or copper-nickel jacket. So, at a guess, you'd want to replace the steel with something much harder and/or denser. Tungsten, maybe? I dunno. Depleted uranium would probably do it; I've never heard of it being used in anti-personnel rounds, but in cannon sizes it pokes holes in tanks quite nicely.
I am an engineering manager and I am explicit about telling my team that they should expect and pursue personal career growth during their employment at any company. My challenge is to figure out how keep this aligned with the company's needs.

Hardware Teardown of Tesla Autopilot Module
Two clarifications:

When I say "lifetime employment at a single company," I refer to spending one's entire career at a single firm.

When I say that employment is a voluntary relationship, I mean that the employer cannot compel an employee to accept a job offer, and that an employee cannot compel an employer to extend one.

Just wanted to add, I think it is regretful that it was not possible for Odoo to grow a business on free software. I hope to be able to best Odoo at this some day, in a different domain.

At the same time, I am unapologetic for classifying pinky07's language as marketing. Evidence of marketing-speak is in "open source" instead of "free software", "open core" instead of "proprietary extensions" and other things such as "top notch usability", "best of both worlds".
If you can reliably hit a target that small, you could just shoot the other fellow in the eye and not worry about armor.
Apply HN: Poor Man's Apple TV
Another jab at cheesy taglines
a) Build your own Roku/AppleTv
b) Democratizing Video publishing / Video Publishing for the masses
c) Buzzword loaded - (Hyperlocal) Video publishing Infrastructure as a service

What is this about?
I am building a system which will allow you to convert your Android phone into a VOD streaming device and serve it to people within 100 mts range without Internet. A system, that will allow anyone to provide on-demand content without any data cost to the end user.

What's the purpose?
Imagine you are a <Business> willing to provide on-demand content for <Media Type> to <Target Users>.

So you can be
a) An Airport, Shopping Mall, Train station, Hotel serving Entertainment & Movies to Travelers
b) A College serving Educational content to Students/Professors
c) A Coffee chain who also wants to entertain customers with Videos
d) TV-rejected channel serving channel content in Trains, Coffee shops etc..

Bonus Edge case
e) An user using it as a Settop box to cast available content (based on their subscription) to their TV;

Extreme Edge cases
f) Shops pushing formatted content like catalogs, offers
g) NGOs/Government using this to push regional content for awareness, education etc.., in remote areas with limited internet connectivity

Replace <Business>, <Media Type>, <Target User> with anything. Combinations and possibilities are endless. Whoever you are, you can easily publish content to users at your desired locations.

How to make money?
3 most common ways
1) Charge monthly subscription to Businesses for using VooWIN-S, charge $x per GB of content stored etc.
2) Add in-roll advertisements to content for more money, share a part with businesses/content creators
3) Create a matte-black sleek box and sell that to businesses as the Local server.
I asked Dr Rabiei that very question by email yesterday, and she is working on it:

"Let me start by saying that it is not a crazy idea and is actually what I have been working on recently. I even have a proposal in DARPA on testing the performance of the material at supersonic speeds. At this time, our data covers up to a speed close to 1Km/s as you mentioned. We have not tested the performance at higher speed and that is what I was hoping to conduct soon."

(I asked if it could be used for space debris at 8-15km/s, and apologized for asking a crazy question)
They are not "fully unrelated". The backquote syntax for constructing lists was primarily designed for macro programming. See the paper Evolution of Lisp by Guy Steele and Peter Gabriel:

"Macros took a major step forward with Lisp-Machine Lisp, which consolidated the various macro-defining techniques into two standardized features that were adopted throughout the MacLisp community and eventually into Common Lisp. The macro defining operator DEFMACRO provided list-structure destructuring to arbitrary depth; the backquote feature provided a convenient and concise pseudo-quoting facility. [ ... ] Backquote and DEFMACRO made a big difference. This leap in expressive power, made available in a standard form, began a new surge of language extension [...]" [3.3]

Firing is rejection, it does not necessarily mean that the person being fired has anything to do with it. Whole unit moving to a different city, moving to a different tech stack. Brining in pals of the New Director, etc. etc. There are 1000 reasons, but Firing is REJECTION. At a human level, only the vexed are relieved that they are fired, most even after understanding the big picture are not in a rejoicing state of mind, because they have to find some other way to find lost Pay. So, no celebrating loss of Income is only fitting for few and in most cases a Sadistic ritual. Its a different thing that co-workers take initiative to send off a good bye, but the company doing it looks dubious and the whole "Graduate" ritual is sadistic.
> Don't just believe that because something is trendy that it is good

The JS community would do well to listen to this advice. I see a lot of JS developers choosing a library or framework without putting a lot of thought into considering the long term tradeoffs of using such dependencies. This is acceptable for side projects as they're done for learning, but it's irresponsible if you do this for production codebase.

It saddens me that the choice of a tool is driven by resume or coolness factor rather than being the right tool for the job.
What I understood was that, if GD is allowed to sit in an account, it will eventually convert to USD at the reserve rate for that account, thus losing value (assuming GD=USD in terms of purchasing power). Wouldn't this discourage people from keeping large sums of GD in their accounts?
