Does HN know about Bubble?  Here's a quick demo integrating 3rd party APIs
I would choose Symfony. I believe it matches all of the above criteria.

And it has:

- amazingly simple upgrade paths, backwards compatibility guarantee on minor and patch releases

- regular, non BC breaking, updates and new features

- corporate backing

- large ecosystem of "bundles", which are Symfony's addon system

- cli tool for scaffolding, debugging and more

- strong conventions that help keep code structure clean when you are in a team of 2+ members
NASA SLS Qualification Booster Test
What polynomials are being derived, and from what premises? Are you thinking of how to derive series solutions to differential equations or something? I'm unclear on what you're getting at here.

(Or, oh: did you mean "differentiation" when you said "derivation"? That would fit what you've said. Sorry for the pedantic post; I'll just leave this here in case anyone else is confused.)
If you don't have to name things, you have zero chance of getting bug caused by naming things

That's why i love anonymous function. it frees me from names overload
I asked myself the same question, and did read some papers, but could not find a recent comprehensive survey on automatic fuzzy rule generation (I admit I gave up after ~15 minutes).

What I found did not convince me that it would fare better than an off-the-shelf (somewhat) non-interpretable statistical supervised learning algorithm.

It can be a nice way of bootstrapping the rule writing process, or to go the other way : to discover and analyze new expert knowledge by looking at the rules.

But performance-wise, I would go the machine learning way anytime.

Also, Inverse Reinforcement Learning seems to be very promising : one guesses the reward function by observing the expert acting.
What Are Some of the Worst Debugging Nightmares?
I love it. I've wished this feature implemented for quite some time.
It should be possible to put limits on the lost energy of individual components, and in doing so, quantify the range of the problem.

e.g.: For now, let's assume that the wheel is a torsional spring, we're putting a force of 1000N (~100kg*g) at the rim, (roughly 300NM torque) and it deflects 1 degree. The energy that goes into the elastic deformation of a torsional spring is k(theta)^/2, t=k(theta), so energy = t(theta)/2. Plugging the numbers, you get 2.5 joules.

Now, 1000N is a lot of force, and you're only likely to have that level of force with a heavy rider in a very low gear. (i.e., your tires have a coefficient of friction around 1, so that's implying 100kg on the back tire just to prevent wheelspin) But 2.5 joules starts to sound like it _might_ be measurable, and maybe look at the numbers a little more closely to see if they're reasonable.

I'm only a fairly decent rider, but even then that's only about 1% of my 5 minute output, (if you assume 1 power stroke per second).
The framework's language should be PHP, not Python.
Laravel isn't developed by a company.
no... nothing to do with that...

This is about visually grouping related things together, not decomposition of functions.
This is well put. In judo, for example, most throws are pretty simple in having a readily discernible fulcrum. The setup and execution of the throws are efficient and reliable.

In aikido, the point around which someone falls can often be floating unintuitively in space after a combined sequence of off balancings that are neither intuitive nor natural. I study aikido primarily today--not because it is easy, but because it's hard. I'm also utterly unconcerned with self defense. I train for those moments when everything is in alignment and either I or my training partner go vaulting effortlessly through the air. I wouldn't count on that happening in real life.

In terms of self defense, people are almost always better off 1. giving an attacker what they want in terms of money or belongings, 2. Running away, 3. Fighting dirty--in that order.
From an urban planning perspective the typical big box build of 100,000 sqft of box with 30 acres of parking lot is a disaster. I don't think retrofitting them is the correct answer.

I've always felt that big boxes should have to put their demolition cost up as a surety bond before construction. Should the store close or go out of business the land could be returned to a field.

It generally takes me much longer to parse data in Python (I use Pandas sometimes) than in Excel/Access but I like to think that's because I've put much more practice in the latter and have to spend more time reading the docs for the former.

You be the judge of that. Compare

e^(iπ) = -1

to

e^(iτ) = 1.

The whole business of re-writing the identity as

e^(iπ) + 1 = 0

is nothing but a hack to get around the weirdness of π as a constant.
For this to work, every aspect of the simulation would have to match up with real world circumstances.

...which would mean no secrets.

...or weapons that, when used, obviate many degrees of secrecy, like nuclear weapons.
Actually, Symfony has corporate backing with SensioLabs, if that's the company you are referring to, but Symfony is also largely developed by the developer community. You can submit patches, feature additions and they can be merged if there is a consensus on the quality and usefulness of the patch.

I think Laravel has the same development model.
Yes, LINQ is really good. With these news i am willing to go back and try it in some more project.
A lot of the benefit that comes from this code storage method doesn't really seem like the best solution.

The presenter in the video linked in this thread that this is very advantageous due to cross dependencies. I don't think that this is the correct way to handle a cross dependency.

I'd much rather handle it by abstracting your subset of the problem into another repository. Have some features that two applications need to share? That means you're creating a library in my mind. This is much better suited for something like git as you can very simply use sub-modules to your advantage.

Hell, you can even model this monolithic system within that abstracted system. Create one giant repository called "libraries" or "modules" that just includes all of the other sub-modules you need to refer to. You now have access to absolutely everything you need within the google internal code base. You can now also take advantage of having a master test system to put overarching quality control on everything.

This can be done automatically. Pull the git repo, update all the sub-modules, run you test platform.

I'd say that's a better way to handle it. Creating simple front end APIs for all of the functionality you need to be shared.
I guess he's meant an open source solution, which both Laravel and Symfony are.
You have to learn how to code
I find it really hard to find anything when it's split into a bunch of smaller repositories. If you're going to do that, you should at least have one master repository that adds the tiny ones as git submodules.
Sloan and NumFOCUS Program for sustaining open source projects
They did only one simulation? Strange to report on details of one single simulation when more makes sense.

Why not do hundreds of simulations, with different amounts of attacking and defending jets. Sounds like fun, must not be a problem to find pilots who want to do this simulation, it's merely hundreds of hours of gameplay :).

Or was it like, they did hundreds, but this is the only one where the AI won, and it had 4 planes while the humans had only 2?
Lastpass, quite happy about it. Best feature is that you can have externals having access to websites via a browser plugin without knowing the actual usernames and password. You can later revoke access easily.
There is a time and a place to make that 'complex point' and I highly doubt that hijacking a thread with wall-of-text posts like these will make that point effectively.

As for your entry paragraph: such veiled accusations are also not worthy of HN.
We need to distinguish between "I don't understand this and I'm not going to bother to try before I start criticizing" and "Ok, I understand why you did this, but have you considered this alternate approach?" (and maybe "I don't understand this, and I think we need better docs here.", but that's already been covered).

(Some) new devs seem to classify themselves into "I'm just a clueless noob" and "I'm the new hotness".
not really a PHP framework
There is also a cognitive overhead when trying to find local variables defined in huge functions, at least when they are split into smaller private (static) methods (with variables passed as arguments) it's easier to track.

Both in the parent method and in the encapsulated child.
I can't remember the specific example, but it was a scenario where the source language was ambiguous but the target required more specificity. It was like "give me some bread" in one language and then when I supplied "give me a piece of bread" it told me it should have been "give me a slice of bread".

While I could see where it was coming from, this would be incredibly confusing for a beginner, who wouldn't even know to report this as a problem - they might conclude that "piece of bread" was just incorrect.
To get a feeling for the size of the problem, the carrier logs all handset accesses on all transceivers. To do location tracking you have to get the carrier to give you access to those logs and you have to have the storage and processing to get finer-grained location based on overlapping transceiver accesses and precise times. It's a bit more than the carrier themselves would do for network quality monitoring, but not even 10X more. With this data your daily routine and divergence from that routine can be learned and detected. With this plus payment information, you've got enough to tell who is doing something interesting in real time.
Really? This seems very similar to problems with variable naming and magic numbers, which are far from bike shedding.
> First, the article is rather vacuous and chaotic in content, and so the motive for writing the article shifts toward drawing attention to oneself ("Oh, look how charitable I am!"). Charity doesn't do that.

There is no such thing as a selfless good deed, and a lot of philanthropists want people to know how good they are. But when selfless and selfish ambition align, as in the case of charity, society itself benefits. That's a good thing.

If a charity is legitimately disinterested in being recognized you never would have heard of it. This getting popular could help the concept spread.

> Second, the article seems to reinforce the condescending/patronizing attitude Americans often have toward immigrants when they're not busy hating them. The attitude consists in thinking that immigrants come from backward, horrible, uncivilized places and that the American is the noble, better educated, civilized, great benefactor.

Which exact text in the article gave you that impression? I feel like I am pretty sensitive to such tones but I didn't pick up any of that.

> Third, if you're paying $60 for a laptop, just pay for it yourself. Getting people to chip in for a 10 year old, $60 brick just looks really cheap. It's not much of a sacrifice, guy.

You too could chip in. As you yourself said, it isn't much of a sacrifice, so why don't you?
Completely false. Across three factories in two states, I don't get "guaranteed" power. In fact, the only place I see basically uninterrupted power is in the nice parts of residential Bombay.
On the subject of affordable housing, not to be argumentative, what is it? Why is that term used? If there was sufficient housing, it would be affordable. Seems to me affordable housing means crap housing, thereby cheap in the current environment where there is insufficient housing. Therefore people should stop talking about affordable housing, and start talking about more housing.
Why Doesn’t More Stuff Go Viral?
This is a part of the plot of Ian M. Banks 'Surface Detail' (2010).

Two parties agrees to wage a war in virtual worlds to decide if virtual hells should be allowed or banned. Unsurprisingly, the losing party tries to move the war in the real world to reverse the losing trend.
Because people expect services as robust and useful as Facebook to be free? Based on how much time people spend using their service, the user's data is hardly a large price to pay. Have certain types of things you like, profession, education, gender, demographic and expect your profile able to be targeted (anonymously) with advertising. Share something public (including anything above), expect any corporation to be able to see or mine it.

Slightly OT but Azure is such a better product than AWS. I was really skeptical because Microsoft has a legacy of doing an absolute shit job at all their copycat products. I happened into some credit and gave it a try during some downtime and was extremely pleasantly surprised. It's as if somebody applied a 2016 interface and usability to AWS.

"clever code isn't." Is what I try to teach all who will listen.

Good code should never be illegible to newbies. And if they can read your code, they can learn way faster.
The true purpose of the tracking, is to track American Citizens. Who cares if they are tracking people outside of the USA? I don't care if the the UK, China or Russia is tracking me. I don't live in any of those countries. But I live in the USA and every agency is better at watching their own citizens instead of ones living outside of the USA.

The USA is not the land of the free, home of the brave.
It's the home of the enslaved and it's been like this for over 20+ years now. It's a pyramid of power and at the top are the rich (Corps, people, families and politicians). Next are the enforcers, they carry weapons and can make you disappear (3 letter agencies, State & local Police, Military). then there's the rest of us: Middle Class & the poor, which are both merging into the peasantry, the enslaved, the human resource. Yes -> resource.

Why is our (USA) "news" Media and government trying so very hard to remove weapons from the peasantry? They are afraid that the peasantry will revolt some day soon.

The Enforcer Class kills with impunity and without consequence. It appears that the powers that be, would like to keep it that way.

How do you deal with updating a vendored library, do all the reverse dependencies need to be fixed in one go?

I can see how it would be an advantage to use only one library version but it could also discourage upgrading since all the cost is upfront.
e^(i tau) - 1 = 0

Seems pretty comparable to me: this one elegantly demonstrates the full periodicity of complex exponentials, while the original elegantly demonstrates how complex exponentials can produce pure negative numbers.
If you have actual enemies, it might make sense to block them on things like Facebook, LinkedIn, etc..

Tojo let his people die to avoid loosing [sic] face.

According to TFA we should probably blame Nitobe for that as well. Frankly this seems as ridiculous to me as blaming Nietzsche for the Nazis.
Hi, I'm a product manager on Google Cloud Platform. Sorry to hear that your credits expired before you could try out GCP.

I inquired on your behalf, and was told that the Web Summit you're referring to is from 2014 (2 years ago), and the credits expired in 2015 (1 year ago), and unfortunately, this program is no longer available.

That said, we do have a credits program for startups (https://cloud.google.com/startups/) but you cannot apply for it directly, you need to "contact your VC, Accelerator, or Incubator and ask about GCP for Startups application details." (quote from the site)

In the mean time, if you just want to kick the tires, you can sign up on https://cloud.google.com for a free trial.
Because terrorists establish normal-seeming patterns of movement that do not diverge from that pattern until it is too late.

Whereas if you take some time off from work to attend a protest, the FBI knows to come knocking on your door to ask pointed questions about your friends.

That's what's pernicious about these programs. They're not good enough to focus on terrorists, but there is plenty of fodder for harassment of protesters.
Interesting, thanks for that info.

I wondered who is financing Telegram since it's really moving fast and it has no apparent source of revenue; it makes sense that it's even coming from Russian government, since they want alternatives to US-owned services.
Ok, only Americans have over-inflated self esteem, that's a different statement. Still wrong, but at least it's a common stereotype.

And I don't think that study supports your comment at all.

> Supporting this contention, our Chinese participants reported liking themselves every bit as much as our European American participants.

> This finding supports our claim that cultural differences in self-esteem arise from cultural differences in self-evaluations, with people from East Asian countries evaluating themselves less positively than people from Western countries.

> Thus, even though cognitive self-evaluations are lower in China than in America, they are not less predictive of global self-esteem. This finding suggests that global self-esteem is experienced similarly across dissimilar cultures

This study finds that self esteem is equally prevalent across the two cultures, and as far as I can see says nothing about how much the participants value their self esteem.
Ha, it wasn't brand new. It was a 2007 that I sold in 2014. Repairs were EXPENSIVE! ($190/hr for labor at the dealer, $130 at the place I went to). Every part was 4x what it would be in a Camry. KBB was about $26k when I sold it.

Thats exactly what i was doing with the elasticsearch plugin for logstash, but i still couldent figure out how to auth vanilla http requests to it from kibana or the like... Then i decided id wasted way too much time on this, and would just build it myself. Other services such as bonzai support basic auth which i would have almost preferred :/
Huh, couple that with an aircraft not bound by human limits (no life support, much faster maneuvering with no loss in decision making) and it should be awesome. And terrifying.
One argument in favor of tau is that in many formulas pi
often has the multiplier 2 in front of it.

And an argument in favor of pi is that many formulas do not have that any multiplier in front it. So this cannot be resolved without quantitative evidence of the number of formulas using either one, including their frequency of use.

Of course you can construct infinitely many formulas, but most of those are used a vanishingly small number of times. The question is what common formulas use pi or tau. How often would people actually have to write, read or say a factor?
>Neither Android nor iOS support [pairing ... via the Out-of-Band method].

I'm not sure this is actually true (unless you're talking about bugs with individual manufacturers implementation on Android?). Both iOS and Android support SSP with OOB key exchange via NFC.

There are lots of products that have been available that use this for pairing/connecting, eg: https://www.bose.com/en_us/support/article/pairing-a-device-...
I had these concerns almost 10 years ago [FB "friend" request from my boss, WAT?]. Clearly, the ship has already sailed and nobody is moving away (at least not for that reason). As others have mentioned, Google Plus had an elegant solution that I quite liked, and was never truly replicated by facebook.

As a father, I've started building my own web presence for my family. I have no desire to upload pictures of my daughter growing up to Facebook, and I definitely don't want all of these photos shared with everyone I've ever facebook friended. Right now, I've got a bunch of photo galleries on my-daughters-name.com, but I'm going to have to re-think this strategy since we're expecting again next month.
Except that no one will ever trust investing in trade with Britain again after this. "British interests come first", in Britain. Brexit erased what is now $2.8 trillion from the global markets, devalued what was thought to be a strong safe currency, losing UK territories and has no leadership to speak of taking any sort of accountability for this disaster.

To the rest of the world it's shocking and infuriating to witness. You see a nation that will be more competitive, we see a nation in freefall collapse. Even here in the USA, we are not on board with this. Our banks are pulling out of London as we speak.

No banks, no pound, no stability.. no leverage. To the rest of the world from now on, British interests come last.
The so-called "cyber war" will be a very important component of any future war between nation states. Taking over the enemies SCADA systems, power grid, net infrastructure etc. can do massive economic damage with few casualties.

I don't think we'll ever see a civilized form of war where no real harm is done, because abiding by the rules of such a war is not a game-theoretic equilibrium. If a party builds a real army in addition to the simulated army and uses it, it will win the war.

Nice work, thanks for the insight!
I have also worked with mono/multi repos. My conclusion is the same. A mono repo is much easier to manage. It is a shared repository but every team manages their own runtime instances. Each team releases at their own pace. The repository is always consistent, no need to manage inter-repo dependencies. You really get the best of both worlds.

Coincidentally, I have been reading "Building Microservices" from O'reilly and I still don't see the benefits.
MAD is the future. And righteousness is the enemy. Don't mess with us. Don't mess with them.

Also, do the world a favor, and don't innovate new weapons. They leave an indelible affect on the collective mind.
Not entirely. Particularly in America, housing is made as absolutely huge detached houses with two car garages and a huge garden. Nothing wrong with that, but in the space of two of those houses you could build an apartment building with apartments that are a lot more, yes, affordable.

Space is finite.
You do mean the marginal tax rate, right? Not the average tax rate. To be taxed @ 42% (average) in Germany your income would have to be way north of 300k€ [1]. With that kind of income, your social security (health, unemployment, pension) would already be somewhere below 10% so nothing to complain about, really, given the benefits (yes, I know the benefits are no longer what they never used to be).

Add to that the absurd housing costs in, say, London, and things don't look too shabby for Berlin. Although you need to be tolerant towards the locals. I can understand some people having problems with that nonchalant "don't care if you care because, you know, I don't care" attitude that sometimes shows. But if you're capable of letting the occasional inflammatory/stupid remark slide, these guys and gals are quite nice. (Protip: This ability is great to have pretty much anywhere. Hanlon's Razor, anyone?)

To me, London is great to spend a few days of vacation. The atmosphere, the people, British humour, all great. Still, I never felt the urge to permanently move there to work. Too crowded, hard to get a decent flat... I guess it's not always just the money.
