I see what you are saying, but, in general, I think the aviation industry has taught us that people are pretty price sensitive when it comes to transportation. Uber is quite expensive, so the risk you run is making people think "Expensive" when they think of the Black Limousine service (which is incredibly awesome, BTW - totally appropriate for dates where you want to drink, or taking executives out to a meal).

I don't think twice about using UberX/Lyft right now - and certainly would never call a taxi in an area served by them.
I thought about it, and I'm still waiting for someone to answer this. Good question.
I went to go see if they actually did say "amateur hour" (they do, amazingly) and in the process noticed this: "If you run to the press and trash us, it never helps." It blows my mind that they're willing to say that so explicitly.
Ada get compiled to machine code, so of course it can run directly on the CPU.

There's also no reason it can't be used to write a compiler and there's probably several Ada compilers written in Ada. I'm not sure what you mean about binary data having to be embedded in the code generator; you can easily generate arbitrary binary data from almost any language.
My kneejerk reaction was "oh my god don't dump a general-purpose language into the runtime just to write mission scripts," but this is actually a good example of how to do it: The DSL defines some data structures that the C++ code uses, and has a direct handoff of the emitted results from Lisp into C++. Lisp doesn't have to interact with every frame of the game.

If you start exposing the engine in arbitrary fashion, things go south rather quickly; the scripting language will never stop finding more things it happens to need to get access to, and then you have an inner platform with boilerplate abstractions that make for worse tooling than whatever you started with.
It's nothing to do with iCloud
Isn't it a neat idea, that in so few years we may see the end of the need for a donor registry? The end of your body rejecting a new part, the end of anti-rejection post-implantation medications? Massive, limb-destroying battlefield wounds completely fixable?

And eyes - eyes and ear drums and nerves and...

...and reattached spinal columns. It's all coming, and many of us will be alive to see it.
Interesting, they've always logged in to my submissions. Process is truly random imho.
We don't tend to write that much justification (at least in industry).
I used to work for a company writing application essays for Chinese students. I didn't write them myself but I have no moral objection. The requirements are bizarre - effectively "tell us what you know will make us like you but hide the fact that you know we want to hear it".

Should you tell the truth "I love CS and play it in all my spare time, I'm obsessed with it and usually don't get enough sleep for school because I'm so committed staying up late at night shooting people" or tell a story about an incident at the beach that makes it look like you have amazing management skills? Who knows!

University selection is ridiculous and I support any attempt to bring fairness to it like these services.
> Eh, casual friendliness is one thing, telling all of your employees/contractors to fist-bump customers is something else.

Totally. You're not wearing the minimum pieces of flair again, right? That whole concept of forced friendliness makes me ill.
The parts involving humans.
To make a huge positive benefit in our transportation system and built environment we need only take 10% of cars off the road, so I think they won't come to take away your family car just yet. Certainly there are many excellent reasons to own one. But on the other hand the impossibility of car-free and car-light lifestyles are overstated.
Plenty of line still have drivers.

The only fully automated lines are 1 and 14.
> You can't price businesses as though they will have incredible growth without some discount for the risk involved. One of the risks is competition.

I'm just gonna go ahead and assume that the investors understand this basic principle perfectly well, you're not being cleverer than them by disagreeing on the valuation, you're just using different assumptions about how incredible the growth could be and how large the risks are.

If Whatsapp can sell for $18 billion I don't see why Uber can't. Uber, after all, has an actual business model and income stream.
I lived in LA for a year and don't even have a license. I bought a road bike and cycled to and from work, though if drinking was (frequently) involved I'd throw my bike in the back of a cab. Assuming the average fare was around $60, and I used a cab five times per week, that was $300/week. I was considering buying a motorbike to evade this rising fee when our company was bought by HTC, the company reshuffled, by job disappeared, and I was suddenly placed in to a US visa expiry grace period where I had 10 days to get out of the country or face being an illegal immigrant (despite many people wanting to employ me, I had to leave and return to comply with their visa rules). I opted out (once bitten, twice shy re: visas), and was very glad that I only had to sell my road bike at a loss... rather than a car.
Not so much begging the question, but making an assertion that I don't have space to prove. How could I prove that modern physics is correct to someone who had perused a physics textbook and concluded it wasn't worth serious consideration?

For military aircraft, there are far more hours of maintenance than flying time. It's a factor of 10-20 in the other direction.

I had no idea Boeing was subsidizing Midway Island in order to provide an ETOPS alternate airport.

Also, 5.5 hour ETOPS? That's crazy long!

Build consumer demand on the site first and you'll be able to sell something in the long term. At least that's what I'm hoping works with my current project.
"...are not ready to be distributed and cannot be be approved."

I found a typo, I'm rejecting Apple's App Rejections page.
Did you even read the story?

It's about IBM mainframes (not Unix systems) on an uninterruptable ("immortal") power supply, a VAX which wasn't, but which could survive reboots in pretty good shape. Except when handling world-changing financial transactions.
Unless it favors them.
Yes, was parent claiming that C has a lot of "certified" tools as much as Ada does? The phrasing was ambiguous.
Fairness is not concomitant to a spare 2K$.
Fairly obvious extension: when arrived at a composite image, choose the one image from the set that is closest to it and show that instead of the composite to get a sharp version.
You are mistaking security and ethics. Yes, it is up to the university to make sure that people aren't cheating. No, that it no way makes it ethical to cheat.
Funny, I used to work for DataRealm (impressed the OP capitalized it right). Wasn't there when they sold the serve.com domain, but it was a big deal for them. Everything internal used serve.com (including email addresses) and switching to Datarealm.com was a lot of changes. As a small business it's hard to say "cool URLs don't change" when you're just trying to get by.
malloc / free style memory management has unbounded latency, too. Though Ada might do something even more conservative.
ZFS still protects you from bitrot when compared to ext4 over mdraid. When you get to many terabytes of data, it's almost guaranteed that you're going to lose something to bitrot. In my case, my most recent scrub detected and repaired 1.58MB of bitrot. And in any given month, `zpool status` will show one or two checksum errors as having been corrected in real-time, as I was working with the corresponding files directly.

This is probably the number one thing that excites people about ZFS over any other solution, and it's something that isn't really easily implemented on a standard RAID + standard filesystem arrangement, since this sort of functionality depends on the filesystem knowing about the underlying disk arrangement.

"ZFS uses its end-to-end checksums to detect and correct silent data corruption. If a disk returns bad data transiently, ZFS will detect it and retry the read. If the disk is part of a mirror or RAID-Z group, ZFS will both detect and correct the error: it will use the checksum to determine which copy is correct, provide good data to the application, and repair the damaged copy."

Deaf people can drive well.
Nobody knows anything about the real origin of the leaks yet. If nudes of famous people are the only thing that come out of an iCloud bug that massive, then some people have really lucked out. It seems like a silly thing to waste this kind of exploit on, when it could be used to read all of the files of virtually any OS X or iPhone user. That makes me think this isn't really an iCloud exploit.
Is there any support at all for the implication that this anecdote has any more than a humorous and coincidental relationship with the 1987 stock market crash?

I've run across this story more than once. It's amusing but also more than a little troubling if that is in fact how fragile the global financial system is.
The dmd D compiler has a built in coverage analyzer, while not quite what you describe, comes close:

|bool foo(bool i, bool j) {
2| return i ||
1| j;
|}
|
|void main() {
1| foo(true, false);
1| foo(false, false);
|}

It'll give an execution count on each statement, and logical expression operands count as separate statements. I've found that when this is used in conjunction with a test suite to ensure that the tests cause every code path to be executed, the code becomes remarkably free of bugs.
> I'm sure you're aware of this, but the high demand from foreign language students is likely because US colleges often have a foreign language requirement.

I read that to mean foreign nationals (non-native English speakers), not students studying foreign languages (which rarely have long essays for introductory courses). That people with poor English skills would use ghostwriting services (like the article author's clients) seems pretty intuitive.
A certified C compiler a la CompCert is still nothing like Ada Spark. C just lends itself too easily to error.
So if 10% of the people outperform the market and they all happen to be value investors", is that a random event?
There might be further reaching impacts that we don't know about yet.
Uber has slipped in terms of standards too. They have been adding drivers like crazy in my area and apparently to save time they have stopped meeting new drivers in person all together. The driver I got didn't get the memo about having a clean car. It was his first day on the job and the interior had all his personal junk in it as well as a bunch of garbage from fast food visits past strewn about. It was truly disgusting.
Thanks, excited to roll out the proper v1 - personally, I did not like the experience of opening so many different tabs to check out featured products so the same page navigation play is where I would say that it might be better than pure RSS

In the meantime, I'n curious, is there something you can think of that might make the application more valuable?
Whatever happens, it's very likely that only one of them will go public.

And given how indistinguishable both have become and how non-sticky their service is, it wouldn't surprise me if the very existence of two competitors that are so similar makes it impossible for either one of them to reach the kind of profitability that's a requirement for IPO's.

Kudos for disrupting the taxi industry, which was in dire need of a kick in the butt, but I think both companies are about to discover that profitability is a lot harder to achieve when you have competitors who can run a business that's 100% a clone of yours.

The simple fact that most drivers are working for both Uber and Lyft should be a red flag for any savvy investor.
IPHONE VIDEO TRAINING COURSE- JULES WATKINS IPHONE VIDEO HERO
I don't quite understand what the problem is with the apps you have listed. Is it that because they are "primitive" and the graphics is "ugly" that they should not be popular?

Or is that the rankings have been frauded in some way? And exactly how is that done? Is there anything wrong with using an existing popular game to market a new game?
I see. Indeed, this is the impression that I got from the last paragraph:

> Now that the spheres are done, researchers in different countries will try to discern the exact number of atoms they contain, to get universal agreement on what exactly is the mass of a kilogram.

However, when it is understood this way, I find the previous word choice confusing:

> two softball-sized, near-perfect spheres, made entirely of silicon-28 atoms, … should remain exactly one kilogram in perpetuity

(emphasis mine). If they are made entirely of silicon-28, and the kilogram is defined as the mass of a certain number of silicon-28 atoms, then they will remain one kilogram in perpetuity (by definition), right?
Dynamic memory management is inadvisable in avionics code, making languages that rely on garbage collection (perhaps pointlessly) challenging to use. But in general, there are no restrictions on what language is used. The particular version of the compiler you are using has to be certified, but just long as you can use the language and the compiler to meet DO-178B/C standards, you can use whatever you want. You can use whatever tools you want, if they get certified. You can write your own tools and certify them. Anything goes, just so long as it meets standards.

(Working on some flight management software, I found a bug in our version of GCC. It's free software, right? So I could just fix it? Or even upgrade to a newer version? That would have meant re-certifying the compiler, so it was easier to work around the bug.)

In practice, I do see a lot avionics code written in Ada. I see a lot written in C. I see a lot written in C++. I haven't seen much else. I would guess a roughly even split between Ada and C or C++, with either C or C++ being increasingly favored for new clean sheet projects.
I am quite unclear on where ridiculous, anti-intellectual scientism comes from. Can you clarify?
Well back here in India, you can get a little pushy and people won't say anything. Another thing is "There are absolutely no Queues here". In my whole life so far, I have never been to a Grocery shop where people were standing in a queue, it is always a swarm of people around the counter. Isn't the same in supermarkets though. Shouldn't write more, other
Indian folks here will reprimand me for giving a negative image ;)
NB: wget's '--spider' argument can be used to test link integrity (though it only checks that the link returns 200, not that the content is intact).
I think its quite possible that lyft's schtick was a key aspect that kept it in the game. And the more social experience was a key differentiator. Sure its subsiding but i woukd not discount its importance.
Not to mention the fact that a few times (at least) per year, people are likely to use their cars for much more than just a local public transport replacement, but will want to drive across the country with the car loaded to the hilt with holiday gear of some description.
Try reading the PostgreSQL documentation on this, then read my comment again.
True, but this is the kind of bug that one would never want to expose. A smart person (of the personality type to go into other people's private files instead of performing a responsible disclosure to Apple) would ride it out for years and leak content slowly, so that he continues to have unfettered access to the data of the 70 million+ Americans who use Apple computers or phones.

Something like this would be worth millions. It's not something that gets thrown away unless the possessor is just absolutely, completely, ridiculously naive.

My guess is that the photos in question came from a much more basic password guessing attack, which has historically been the case in these high-profile leaks, like the Scarlett Johansson leak that landed this guy in jail for 10 years: http://www.cbsnews.com/news/christopher-chaney-so-called-hol...
I used one of this series as my wallpaper for quite some time after its initial release. It's useful to remember humans can do extraordinary things.
I was just asking that recently too [1]. I think it's because most "normal" projects, aka web/desktop/mobile apps aren't safety critical, a large cadre of developers prefers dynamic languages that let them program in a completely bottom-up exploratory manner without thinking about types and the like.

Why Uber Must Be Stopped
What? That's a crazy story.
Whatsapp is a paid service and was profitable (probably highly highly profitable)
YCombinator is all tied up with VCs and incubators and such, right? In other contexts such as applying for various types of placements, are people's comment histories reviewed (including whatever amount of doxing is possible via server logs etc) to weed out "bad eggs"?

Cuz, I sure wouldn't hire anybody on here who is condoning or defending in any way cheating in school, even in the most oblique way.
What new languages are being developed that could be even safer than Ada for safety critical systems? Are Agda, Haskell, or Rust as safe or strongly typed as Ada?
I can give some personal experience on this - I started bug/vuln reporting mid-last year. I've reporting a bunch of web-applications bugs that ranged from simple XSS and CSRF to RCE and directory transversal in a range of applications (Enterprise software is rampant with holes).

I've only encountered two non-respondents. Everyone else has thanked and patched within a month and I even gained employment from one encounter! Yet to get a reward, however I do this for a hobby, rather than money.

Although one day I hope to do this professionally! There isn't much work in New Zealand for it though.

EDIT: To clarify, my process is: report to vendor with suggested patches, follow-up 1 week later if no response, follow-up two weeks after response to see if it's patched, ask permission to use my bug report publicly. In some cases there'll be a phone call from the respondent to ask about my background and see what my intentions are. Occasionally they schedule a coffee/meeting.
Your team's health is proportionate to the amount of “undiscussables”
There is also the dynamic language run-time (DLR), which as a generalization of LINQ (to support statements) is pretty powerful when writing up these tools on .NET. I use it often in my work.
At the time, it was a top-secret government project. That plane was the best spy resource our government had. We did not want the plane, nor its designs falling into the hands of others.
The great thing about Uber versus Taxis - is that you were able to downvote him down, and presuming others do as well - he will no longer be driver for Uber for much longer.

Compare that to crazy taxi drivers with really terrible cars - they stay in the system for many, many years.
Could it be a poorly-disciplined employee somewhere? At one of the phone companies? (Or, dare I say it, the NSA?)
> A smart person

I don't think a smart person would do this.
To prevent them from falling into the wrong hands and another nation building an SR-71:

> In 1968, a presidential order required that all molds and tools used to build the SR-71 be destroyed so that the plane could never be built by anyone again. This also meant that spare parts could not be made, so if there were any major problems, planes in storage would have to be cannibalized.
http://www.strategic-air-command.com/aircraft/reconnaissance...

> 8. How many SR-71's were built? 50 Blackbird airframes of various designations. The dies or molds were destroyed as directed by then Secretary of Defense McNamara to prevent any other nation from building the aircraft.

Ship it and iterate. As long as there isn't a crippling series of bugs that prevent the users from going through A > Z, then you should be fine.

The man at 18.00 minutes with the question about the mailing list tone. He kind of called Mr. Torvalds out on the way he talks to people on the mailing list. What grounds does he have to say something like that to Torvalds?
> GitHub portfolios

The tricky thing is that github profiles don't always make obvious the amount of real, quality code someone is producing. It's often hidden away in private company repos, or, on the other hand, appears to be an impressive list of contributions but when you investigate it is mostly minor changes and grammar/typo pull requests.
Weirdly, avionics development seems to be moving away from Ada toward C! I personally think something like OCaml would be a better choice...

I think the problem is, there is so much momentum built up around Ada and C usage in the avionics world that there just isn't the infrastructure and culture built up around better languages, so it's hard to make the switch. Even if you have to write a brand new codebase for some small avionics project, how do you justify the expense of doing it all in OCaml when there is already certified compilers and support for Ada?

It ought to happen, though.
Ada uses its type system plus managed memory pools for manual memory management, it's very cool. Safe manual memory management with memory control of C/C++ but the safety of an ML.

> Why are college courses giving "major" assignments that can reasonably be completed in 5-10 hours by a smart person with no training in the field?

Because that's precisely the point of a liberal arts or humanities education: to make you able to look at a new field with a modicum of critical thinking & intelligence.

Within the humanities, it is largely irrelevant post-grad what field you actually studied since actually working in that field (usually the only humanities jobs are in academia) means post-grad study. Instead, that field provides a framework for you to learn how to acquire, analyze, and summarize knowledge.

Hence, it's absolutely expected that any educated adult should have no problem writing in an unrelated humanities field, because they've already gone through the system.

This of course doesn't mean a random person can easily write such an essay (hence the demand for ghostwriting services). Many of my high school peers would've flunked out of even a basic college course. Hence, despite its apparent tedium, college does provide an important certification/funnel—even for mid-level office jobs, whose chief qualification is reading and synethsizing reports.

I do hope you understand how it's unethical to aid and abet people in cheating their way through college. This does a disservice to them (they likely won't learn the necessary writing/analysis skills for the workplace), to employers (they might be hiring incompetent writers), and to society (by credentialing the wrong people, potentially driving out smarter/more ethical people). It's ethics 101 that claiming someone else's work as your own is wrong.

> the heaviest users of the service were education majors.

I sadly suspect that has something to do with class dynamics. Education is not very prestigious and (based solely on the ads I see in the subway) is one of the fields (together with "business administration," "IT management", etc.) targeted at low-income/low-ability people who probably don't belong in college at all.
why do you think they are planning on killing the work?
