If you are interested in the "Living Latin" as a spoken language as Foster teaches, you can't really do that on your own. But really, most people interested in Latin aren't really interested in that but really just want to read Latin. And you certainly can do that on your own. There are lots of textbooks, but probably the most popular is Wheelock's Latin which has the advantage that if you don't understand a particular exercise, you'll have no problem finding someone to explain it to you on the Net.
Fixed spark timing is not that big an engineering deficit for an engine that runs at a fairly constant power setting.

Road-going cars need variable spark timing because they are called upon to efficiently make wildly varying amounts of power. (Idle, cruise, accelerate are all part of the normal drive cycle.) Airplane engines, many racecars, and other similar applications that need to produce fixed, high power for prolonged periods of time often use fixed timing mechanisms.
Electronic meters’ false readings up to six times higher than actual consumption
No, since wired networks are full duplex and are their own collision domains. No need to do carrier sensing at all.
> the biggest expense which is the human driver, so the expenses will drop a lot

This only makes sense if Uber driver's net income is pure profit. Instead I hear they have a set of expenses - fuel, insurance, tires, maintenance as well as servicing payments on the car. Some of these Uber is likely to negotiate down, mainly insurance. But some (cleaning, maintenance, parking, car washes, tires) are currently externalised to the driver and will have to be assumed by the company.

This is even before we get into the details of who manufactures the cars and how Uber comes into the possession of the vehicle (lease? outright purchase? purchase backed by a loan? etc.)

Have you flew above where I live?

Given the number of planes I see in the sky and the data you did.

I live near Paris, and every time you will watch the rivers flowing nearby (may it be Seine or Oise) you will notice this weird patches from the sky near the loops of the rivers. It is/was sand harvesting.

It looks like this: https://www.google.fr/maps/place/Cergy/@49.0222789,2.0684055...

You will notice raw montain near montpellier a hole while approaching ORY from london in a place named cormeilles en parisis.

You may not notice but it may be insidiously happening near your place, everywhere in the world.

Even the desert (cf occidental sahara, UN claim vs Marocco), oceanic islands are targeted.

The law of thermodynamics are saying "any pure enough chemical entities are a resource", and the entropy lost will never be recovered without a way bigger energy than the one for harvesting them.

Thus the reasoning on fossil energy (Hubert's Peak) also applies for sand, water, potasse, alumine, iron ores, bitumes, absestos, helium, nitrogen, coal, gas, uranium....

Why no one cares?

Because there is an economical incentive to ignore the consequence of your actions: the lack of financial liability for the pollution/increase of entropy you are generating.

If you make your own compost and grow your vegetables (lucky us) you can build an intuition of what is wrong here.

But for the other one, our education makes it impossible to understand the slow cycles of resources. So, I bow.
People seek out active managers because it's not a fiction that there are successful ones. They're simply difficult to identify before they become celebrities, at which point they're too expensive for all except institutional investors. Unfortunately, the relative few spur the hunt for the supermajority, who are mediocre.

Keep in mind two other facts. First, this piece is published by the Index Fund Advisors, which implies a fundamental bias against active management (and that's not necessarily bad! Index funds are almost inarguably superior for almost everyone). Second, Eugene Fama's Efficient Market Hypothesis does not have widespread support in its strong form. In the years since his thesis, even Fama has walked back to a more reasonable position that allows for people to beat the market. The weaker form of the hypothesis allows for successful managers, just comparatively few of them.

Do people still use Skype?

There was a time in the past, I used it daily for getting in touch with friends, using chats and (video) calls. It worked very well, I used to love the offline messages feature.

Today I only use Skype once or twice a week to call a single friend that lives in another country, or when I'm in holiday.
Most of the people use WhatsApp calls, Google Hangout or FaceTime.
I tried the first but usually calls quality is awful (i.e. communication is not possible, especially on cellular networks), I don't have an account for the second and FaceTime is limited to Mac and iPhones. Still, there are plenty of alternatives to Skype, and most of the people are using them.

Skype was a nice software. Then they started to change the Mac interface making it worse. On Linux, it was abandoned for years. On Windows, they made it confusing with 2 Apps: the standard one and the Metro one that had just a few of the standard features. The worse was on Windows Phone: just a basic and rarely updated App. Now there is Skype Preview, that it's nice, but I don't know anyone except me that is using it.

Also, in the (far) past it was working perfectly, even on more devices. Until last year (if I remember correctly) sync became a nightmare between PCs and phones with ghost messages, delays (sometimes you would get chat hours-old on one of the devices!), calls ringing only on some devices, or others devices that kept ringing even if you answered on one of them etc.

Oh, and I hated that Skype address book kept syncing with my phone address book, copying all my contacts on Skype. Finally now you can disable this feature.

While it's "only" 52 years old, another plane still in production (albeit under a new company) that's worthy of discussion is the de Havilland Canada (now Viking) DHC-6 Twin Otter[1].

The Twin Otter isn't just nice to fly, cheap, or ubiquitous. It isn't just a mainstay bush plane everywhere. It's still the best plane in existence for certain extreme requirements.

Many different planes can go deep into Antarctica during the summer, but when somebody gets sick enough to warrant evacuation from Amundsen-Scott South Pole Station in Antarctica in the middle of winter, as happened in 2016[2], the DHC-6 is still the best plane for the job. In fact, two DHC-6's went because the only plane capable of performing search and rescue for the first was another DHC-6. There simply aren't other planes out there that can land on a short, frozen runway in the dark of an Antarctic Winter when temperatures are so cold that fuel turns into jelly[3].

Viking has been modernizing many aspects of the Twin Otter, but they're still making Twin Otters. The Twin Otter is 52 years old and still does things no other plane can.

>The only answer I can come up with is that there is a political motivation, driven by neo-Marxism and the narrative that capitalism and big business are inherently evil.

I agree that that kind of rhetoric is in vogue right now, but Uber is definitely not the hill I'd want to die on in making that point.
Well Google is leading the charge, and everyone wants to be like Google so . . .

Keep in mind, modern WiFi uses OFDM where the signal is transmitted via a number of simultaneous carriers offset by very small frequencies. So while the center of the 20Mhz band might be shifted just a little the small carries might be shifted far enough onto each other that the signal is unintelligible.
There is. It's just not always large enough.
The problem is that all or most of the key points for why "Uber has already won" have already been replicated by competitors.

Just for-instance, Boston Metrocab has had a functioning app since at least 2012.

It:
1) Does the same ride-hailing as Uber, in the same way, with real-time GPS locations of your cab.
2) Did not, last time I checked, did auto-pay the way uber does. Is this a hard-to-replicate feature?
3) Are reasonably clean. I find BMC cabs about as clean as Uber; NYC cabs dirtier.
4) Circular reasoning. "Taxis can't do better because they can't do better."

Really, only point 2 is valid, and it's been replicated by other competitors (e.g., Lyft).

So what's Uber's moat?

Oh, yes, unsustainably low prices.
True enough, if there's budget/schedule scope for crafting, we certainly should.

In the short-medium term Electron apps will probably hit that ole VisualBasic sort of sweet spot: for learners to write xcopy-distributable (I'd hope?!) "apps" to share with peers, and for day-to-day hackers writing the "messy no-performance-required" one-off tools that need a tad more visualization than can be effected with quick custom CLI println tools.

I too fail to see "a programmer's text editor" as the "killer app" for Electron of course ;)
The main attractive of uber is the price. Many people won't think twice about jumping to a competitor if one shows up that is cheaper than Uber.

There are so many complex things at play here, but...

1) there are people who work for major institutional investors (think pension funds) who are paid very well to pick managers. If they just pick beta funds, it is hard for them to justify their salaries.

2) not all market participants are interested in 'beating markets'. Many are interested in matching the liabilities to their assets or accomplishing another goal.

3) I believe that there are some managers that are much better than other managers for at least short times. I do not believr i know how to pick them, but the idea that it may be possible may make this bet worth it.

4) If there are good managers, the investment world is winner take all and they will accumulate a lot of assets.

For a type-certified airplane (roughly "one built in a factory"), such an engine swap would require a Supplemental Type Certificate (STC). The process of creating such an STC would require a fairly extensive engineering study as well as flight-testing to prove the new engine was suitable in all regards. During that time period of developing the STC, you would place the aircraft into "Experimental" category to do the testing.

While possible, economically "it's not going to happen".

For non-type-certificated airplanes, there is a large grassroots community around "Experimental-Amateur Built" (E-AB) aircraft. EAA (www.eaa.org) is the largest owner club; they put on "Oshkosh" every year, which is the world's largest fly-in (of E-AB and factory aircraft). In E-AB, the constructor of the airplane has nearly full latitude to choose their engine setup (and to change it later). My limited experience suggests that those who start with tried-and-true aviation-origin engines have a higher success rate with their projects.
How Wealthy Donors Drive Aggressive Foreign Policy
I think one can have this attitude with a lot of things. The job which you were supposed to get is the one you got, etc. It must then be that 'supposed to' doesn't really have any meaning, or the opposite, that things are going according to whatever grand plan there exists for us. Who knows.
Which this doesn't have.
> That said: I think we should. Electron is problematic and you can always tell an Electron app when you see it because the performance is so terrible.

Is this intrinsic to Electron architecture --- or just the current realities of the sort of JS people tend to write, thrown at the JS engine that Electron wraps?

What I mean, if the final executable is actually some sort of embedded Python interpreter and "Electron" is a bunch of shoddy Python scripts messing with WebKit and Gtk/Tk/Qt/whatever then I'd steer clear. But if the non-3rd-party parts are solidly high-perf-engineered, I'll remain interested..
Looks great! Very intuitive. This is something I could actually see myself using instead of argparse; and being able to generate a CLI from a third party object is amazing!
JavaScript got at least part of its popularity because it was the only thing that ran in all clients (Flash and Java were close, but had the disadvantage of being owned by a single big player)

Similarly, node.js got at least part of its popularity because it was the only thing that used _the_ language you can also run in the client.

This levels that playing field at least a bit (completely, if it can manipulate the DOM with little friction)

I expect to see many server-side languages will fairly soon compile to WebAssembly, so that they can position themeselves as an alternative to node (For example, I think Apple would be stupid if it wasn't working on a Swift-to-WebAssembly compiler).

In my book, that is good; competition in that field will improve all tools.
Active management for maximizing returns is a fiction. Active management for controlling risk and volatility is not.

What original predictions? All the old ones I've seen show exactly what seems to be happening: an accelerating warming.

The majority of the 0.74C is in the second half of that 100 years, just like one would expect.
Very good question. Planes used to be so much cheaper, too.

I'm not an expert, but from what I gather there was this issue where product liability law suits drove aircraft manufacturers out of business. Even Cessna went bankrupt and was sold to Textron, and production of even the Cessna 172 stopped for a decade or so in the mid 80's.

The General Aviation Revitalization Act was supposed to fix this, not sure how much it has (see link at end).

Would love to hear more about this. Regulation is clearly a huge factor.

By the way, as much as one can complain about the general aviation scene in the USA (regulation, FAA, ...), on a global level it's still paradise. In Europe it's more complicated and expensive and cumbersome, even though the EASA is slowly moving in the right direction as far as I can tell. In Asia, general aviation is nearly unheard of. Australia has some, though it's really too big :-) Interestingly, Africa has pockets, e.g. in the south (South Africa, Namibia) and east (Kenya).

This is not true. Mutual funds and most hedge funds are designed for capital returns these days, and few of them optimize for capital preservation, despite the name. Beyond that, a minority of funds are consistently successful at beating the market.

> I've been trying for the last 3 days to wrap my work style around cabal/stack...

You have me puzzled! You can totally ignore/skip cabal and just use

- to create project dir with stack.yaml

stack new myproject simple

- to ensure all dependencies and a ghc for that stack.yaml are present

stack setup

- to rebuild any changes

stack make

- to live-code in your project

stack repl

- to run interpreted any one of your mains:

stack runghc some/tool.hs

- to grab 3rd-party dependencies for the project:

stack install some-external-lib

Pretty similar to most other modern languages' "canonical" build/run/package-management tooling really.

> Ideally, I'd be able to write Haskell that compiles into concise, trimmed down, readable javascript bundles, (as you can compile OCaml with bucklescript). But I don't think it's really possible right now. Once upon a time I successfully managed to get ghcjs to compile code using a library I was interested in. It spit out a 1 MB bundle, without even doing much of anything.

Well. For JavaScript from Haskell, other than GHCJS that "compiles the whole runtime system" to multi-MB packages, there's more lightweight options (outside of PureScript/Elm), namely: Fay and Haste. Fear not, a new from-scratch transpiler is also next on my agenda however! ;) that's because Fay parses Haskell to transpile, but I definitely want to transpile from the highly optimized and richly annotated-with-compilation-hints "STG" IR. Not sure how Haste does it, but I'd rather have full control over the JS I emit over the coming half-decade anyway and it's certainly a bit dated (ES 6+ can be emitted so much more "compactly" than legacy JS!)

That being said, from what you're saying I think you're better served with ReasonML or PureScript as these projects seem to already have matured somewhat yet also not-yet-stale =)

Looks pretty good. But if you're going to open source it, you might as well make it a proper Python project and conform to style guides (Google's own for one). This one has all the tests in the same directory as other files instead of a 'tests' directory, it's missing requirements.txt and method names start with upper case.
There's only one certificate in the FAA line up that requires actually spinning an aircraft. In that sense the Cirrus makes a perfectly acceptable trainer.

Ask HN: How to get into the space industry as citizen from 3rd world?
I'm a web dev in my mid 30s and my country doesn't have a space program. I've always been fascinated by space but it was never a realistic nor possible route in my youth. Now that I'm somewhat settled in my current career, I wonder if it's possible to pursue breaking into the space industry.

Specifically, I _want_ to go to space. But I am willing to settle for a career that helps send people into space and hoping to get a trip as a retirement gift before I die.

There was a terrible "aviation winter" in the mid-80s with product liability concerns, economic issues (high interest rates), and a spike in fuel prices resulting in the bankruptcy of several manufacturers and other manufacturers stopping the manufacture of piston-powered airplanes entirely.

To me, the more interesting question is "why were the 60s and 70s so good for GA?" De-regulation of airlines was probably one factor, but it can't be the only one.
