Most "Uber for X" companies are not actually "Uber for X". That's why they're struggling. "Uber for X" does not mean "on-demand for X". On-demand has always been a tricky business. SpoonRocket, one of the companies mentioned in the article, is clearly "food on demand", not "Uber for food".

What are the essential differences? Uber delivers a simple product, a car ride, that even a minimally skilled contractor can complete. SpoonRocket delivers pre-made meals. Complication is added in having to design, cook, and package pre-made meals.

For SpoonRocket, overhead costs exist in the forms of delivery fees: for Uber, no such fees exist. The delivery itself is the product. For SpoonRocket, the real product is the (instant) meal, not the delivery. SpoonRocket had so many costs that in order to turn a profit, they ended up trying to save on meal quality -- and in turn promptly lost their userbase.

SpoonRocket cannot meaningfully differentiate itself from its competitors: who really wants to try another service for delivery meals when you could just order GrubHub or Seamless? The folks at SpoonRocket were effectively trying to start a restaurant, which is a hard business with tons of near-equivalent competition. On the other hand, Uber clearly and meaningfully beats taxis, both in terms of price and experience.

We know that on-demand businesses are hard. We know that food businesses are hard. Combining them, guess what? Not easy.

Let's talk about an actual "Uber for X" companies that is doing well: take Airbnb. Airbnb allows you to take your existing property (spare room, couch, whatever) and with extremely little effort begin renting out access to that property, but only when you want. This is similar to Uber, which allows you to take your existing property (car) and make some extra money by driving every now and again.

The conclusion here is that Uber is an on-demand service from the customer side only. From the service-providing side, Uber is among the very first of its kind (you can tell that from the fact that Uber has completely subverted the employee/contractor distinction -- there's extremely little legal precedent for a business like Uber).

Thus, it is a severe mistake to look at other businesses that provide on-demand services from the customer side, and to conclude that such a business is "Uber for X". It's only "Uber for X" if it's similar from the service-providing side, which very few businesses are.

2)We are NOT from Nebraska, but we found an awesome tech-forward bank in Lincoln Savings Bank who saw a pain point in the 1099 world and got really excited about helping us build out a tax solution.

3) We don't automatically send quarterlies (yet) but we do send reminders and make it really easy to remit that payment every quarter. Shortly, you'll see an automated solution built into the product.

4) In answer to your W-2 question, yes, employers automatically withhold taxes for their employees and remit that money to the IRS throughout the year. Essentially the government holds on to this cash all year and if you've overpaid, you'll get a refund. This is what happens in a fair amount of W-2 job situations, but when you're self-employed, you're on the hook for taxes and are expected to separate funds and pay estimated quarterlies throughout the year - a tough thing to manage on top of client work, life, and whatnot.
Almost exactly decimation.
Factory<MarketDataService<Stock>> marketDataService = new Factory<MarketDataService<Stock>>()

Is objectively less readable than

def marketDataService = new Factory<MarketDataService<Stock>>()

And even the latter is not the best.

def MyClass(marketDataService){

this.marketDataService = marketDataService

}

It's imho the most readable.

When I hear that the US still hasn't adopted chip+pin it sort of sounds unbelievable. This is the country that created VISA International, after all - a fantastic story chronicled in Dee Hock (founder of VISA)'s book. It seems like the financial industry in the US has taken giant strides backwards since then.

I don't understand how these help mitigate fraud in any way. You still have to sign afterwards, there is no PIN which is the way it works in Europe. How is this ANY different other than harder to implement a scanner which would steal the swipe, and those are bound to get implemented sooner or later anyway.

I wonder if this is related at all to the Altera acquisition, and how many of those employees will be affected. Intel had to give up a lot of cash, and take on quite a few redundant employees…
3. Demographic shifts. For example the classic nobody is going to buy cars because we'll all live in luxury city apartments and uber. As if the FIRE sector will simply give up on car loan revenue, those dollars will have to come from somewhere. Or if you laugh at the boosterism people for saying the same things since 1970 and it all fails, then who eats the losses on those luxury apartments and gig economy taxi startups? Either way its going to be very exciting.
So, I haven't used Mongo, but here's a list of things I found to be bad about jsonb (use case was a project where we need to be able to quickly aggregate over large numbers of items with small-cardinality metadata):

1. Can't sort using a GIN index.

2. Stats are shit with GIN indices - Postgres assumes that every filter has 100 matches, every array has 99 elements or something. Usually this works well, sometimes (specifically in my case) it's terrible. Specifically, it means that if you combine an aggregation over a GIN filter with an inner join, the performance will be awful because postgres picked a nested loop join for expected 100 results instead of a hash join for the actual 50,000.

3. This also means that additional expression indices you add basically aren't getting used, because it'll always appear better to the query planner to use the GIN index first. This includes things like sorting.

4. Because of how jsonb is implemented (basically arrays containing fields ordered by key alphabetical), we discovered that we were taking out more and more fields out of our jsonb field and placing them in other columns, which kinda missed the point of it (but was very good that we could do so, yay relational data model).

5. Sorting can become an epic chore if you don't have stuff like enum types etc, especially when you try to combine it with tsvectors.

So, very happy with Postgres, but don't slam people who don't use Postgres because of insufficient json support - because Postgres' json support although excellent has quirks that will bite you with certain use cases. Very good, but not a panacea.
That and when you accidentally pull your card out before the transaction finishes because your patience wanes. Then I just end up using the old magnetic swipe out of guilt.
Also you can't start the process early. At Trader Joe's I always swiped and entered pin before the clerk finished, but it's no longer possible. :(
One must understand that this is re-structuring. Intel is probably letting go of some divisions it no longer intends to pursue. In the not-so-distant past, Microsoft did an internal re-structuring when Satya Nadella became the CEO. It isn't as bad as it is portrayed to be as most people end up getting re-hired in other groups or take the severance and join a new company.
Chip cards with contactless ability work great for speed, but I'm not sure about safety and fraud thing. It's also a matter of having people trained. I rarely need to use swipe, so naturally it takes me longer than entering pin.
This is a very interesting and convincing theory. The same could be said for AirBnB.

So the question is, what other locally-regulated industries are ripe for disruption?

Just a guess, but tech companies are occasionally release % of their workers to clean its workforce, boost productivity and make space for new, young and experienced engineers.

Of course, they might just save themselves a bit of time by introducing all the invasive species at once. Let them duke it out in a battle royale, rather than bringing them in one at a time, to control and/or compete with the previously introduced invasive species.

I don't shed many tears for the species that had a protected niche and never managed to do much with it. In the long run, Earth needs species that can quickly colonize hostile environments and make them more biologically productive.

Interesting - I was suspicious that this "Quick Chip" process they refer is less secure, but apparently it is just a matter of poor implementations requiring the card for the entire authorization process:

"According to Ericksen, the ability for EMV transactions to continue as usual without the card remaining dipped after the creation of the cryptogram is actually already an existing EMV process, but it is just not widely used. With the implementation of Quick Chip, no additional testing or certification is needed from a Visa or EMVCo point of view, there are no changes to the process and the technology is inherently EMV compliant."

They are much slower. Both perceptively because you have to leave your card in during the entire transaction, and we're sending/receiving more encrypted information.

My biggest gripe is the sound for a successful transaction is the same as an error sound. It always causes me to do a double take to ensure it went through.
Again, you didn't cite any actual facts. Repeating something doesn't make it true. You should reply with a citation proving that the rate of temperature rise is an anomaly. Cause right now you're ironically "making shit up and pretending it was truth", in your own words.

Also, noting the fact that the record only goes back 130 years is merely pointing out how little statistical significance climate models based on "the record" have.

See a recent episode of The Allusionist ( http://www.theallusionist.org/allusionist/please ) discussing the difference between American and British English, when it comes to the word "please".

Point 1 is explained, at a high level, in the introduction:

"In Hummingbird,
user-provided type annotations actually execute at
run-time, adding types to an environment that is maintained
during execution. As metaprogramming code creates new
methods, it, too, executes type annotations to assign types to
dynamically created methods. Then whenever a method m is
called, Hummingbird statically type checks m’s body in the
current dynamic type environment. More precisely, Hummingbird
checks that m calls methods at their types as annotated,
and that m itself matches its annotated type. Moreover,
Hummingbird caches the type check so that it need not
recheck m at the next call unless the dynamic type environment
has changed in a way that affects m."

Personally, I think they're pushing the bounds of what "statically" means, but hey, they do say it's "just-in-time static". It does indeed do the checking before executing the function, it just happens to be immediately before executing the function. A paragraph later:

"To ensure our approach to type checking is correct, we
formalize Hummingbird using a core, Ruby-like language in
which method creation and method type annotation can occur
at arbitrary points during execution. We provide a flowsensitive
type checking system and a dynamic semantics that
invokes the type system at method entry, caching the resulting
typing proof. Portions of the cache may be invalidated
as new methods are defined or type annotations are changed.
We prove soundness for our type system."

Based on how their approach works, I don't think Point 2 stands.
I think the trouble with application processors is you ought to have lower prices and margins compared to desktops and servers, so even if they do great there it's not that great financially. Intel is a relatively high margin business so it either needs to find markets where that works, or grow volume very drastically, which is hard given their already very high volumes, or shrink.
Uber provides a better service at a lower price than it's alternative(taxi).
Most Uber for X companies are just providing a delivery service at a higher price.
That's true, especially if you have someone with a chip card who, out of habit, first tries swiping it. It takes him awhile to realize the swipe didn't work and that the reader is prompting him to insert the card into the chip reader.

That "someone" is me, by the way.

Perhaps some people believe that is what happens. But if I were a talented employee, I'd see an 11% staff reduction as a sign to stop ignoring those recruiter emails.

Using your power, whatever it may be, to help others is one thing. Deliberately, actively, perhaps even desperately seeking more power to help more people is another. The first is a form of compassion. The other is a form of pride. Why do these others need your help? Have they asked for it? Are you seeking that power to help or because you like power? Lots of questions that muddy the water there.

There are certain things, like enlightenment, which naturally slip out of your grasp the moment you try to deliberately reach out for them.
Windows users should uninstall Quicktime, security alert warns
but why should we expect increasingly warm temperatures? like you demonstrate, the difference between the span of a human life and the age of the earth is so vast that we really have no reason to expect any significant change in temperatures during the course of our lives, or even the 130 years for which records have been kept (only .00000000028% of the life of the earth).
Well, technically, "the earth orbits the sun" is precisely nothing more than a "point of view" (or a choice of reference frame, if you wish). The laws of physics tell us it's an arbitrary (though very convenient) choice, and you are free to make any other choice you like, such as "the sun and the planets all orbit the earth". Poor analogy, I guess?
Is it catching the type error before executing the code with the type error? The technique presented by the authors does not wait until there's a type mismatch in an individual expression inside of a function. It catches the type mismatch before executing the function. That's what they mean by "just-in-time static". It happens "just-in-time" because it's during program execution, but it's "static" because it happens before executing the function itself.

A Simple Approach to PCI DSS Compliance for Google Cloud Platform
I think that this is the result of the wider economic turmoil we're experiencing since 2008. The US economy, in theory, is recovering but the biggest player worldwide is Europe and Europe right now can't handle a few hundred thousand immigrants - should be trivial given the available resources. Europe has political midgets in a time when at least mediocre politicians would be needed all over the place (France, Germany, UK, etc.).

So I think it's mainly EUs fault. That said if the US fails to regulate the financial sector in the years to come, we're going to see recurrent financial turmoils until we end up with WW3.

The problem is knowing what you are getting into. With big accelerators, like YC, there are tons of resources online and you can get an idea quite easily. For other, it is much harder. Although their websites generally have some information, it's the founders stories that provide the most value. Somehow, it seems that there is more accelerators than content written by founders about their experiences.
