I've been riding Uber since October 2010, and I've chatted with plenty of drivers. Many of them used to be taxi drivers and have told me about how much they prefer driving for Uber. They also tend to be very happy with their income. I remember in particular one recent driver's big grin as he raved about Uber and praised Travis the entire ride for letting him, his wife, and his two kids live such a great lifestyle. His wife would even take the car out and do some Uber driving once in a while while he spent time with the kids.

The calculations in the article seem to be based on just a couple numbers -- such as the 40,000 miles per year that Uber gave for the purpose of cost of ownership calculation, which is used to try to calculate the hours drivers work and the fare they earn per hour. Some real numbers about fares earned would help here. The conclusion is not clearly stated in the "Conclusion" section, but here's my interpretation: If you make certain assumptions about an uberX driver, you find they make about as much as a typical taxi driver. This suggests that driving uberX instead of a taxi does not automatically put you in a completely different income bracket, but I think the devil is in the details. Obviously the spread between different drivers is much, much larger than the spread between taxis and uberXs. If we made a histogram of income for each and superimposed them, they would be two humps with a lot of overlap. It would be more interesting to know, for example, how the jobs of top-earning uberX drivers and top taxi drivers compare.

Then there are implications that Uber is another Groupon, and its financial success is dependent on a steady stream of investment dollars. Well, Uber is making plenty of money. They write software and do operations and the money just pours in. Every user is a paying customer, and the vast majority of users come away satisfied and happy to have a better way to get from point A to point B. The drivers make money and are thrilled. Some people take Uber literally every day. Seems like a pretty good business to me.
Overblown how does it even compare? I've listed a series of links to the major events in chronological order.

It's only a mistake if they recognize it as one, i.e. with a public apology of the same exposure as their original post. They have not done so, or recanted their post, or even recognized Ben's efforts since. Their treatment of contributors is especially relevant given they're now seeking to attract more contributors.

Until then I have no reason to like Joyent or consider using any of their services.

DO-178/C permits virtual machine separation of function on shared computer hardware; this ("Special Conditions") is the first time all three networks have been allowed to share a single network bus. Previously, networks were separated (primarily for historical reasons; the three network domains came aboard years apart; it made retrofitting features like seatback video screens easier on old aircraft) but that separation gave obvious safety benefits as well. Now, when building new airframes, Boeing quite rightly wants to avoid running three wires where one will serve, saving kilograms of mass.

But if we believe VM separation suffices for safety critical software, do we believe it as strongly for network traffic?

I suspect pure marketing. A mainstream player announcing support for bitcoin is still newsworthy. In another year, probably not so much as there will have been a series of such announcements by then.

Even if they don't do a single bitcoin transaction, the coverage and back-links will more than cover the cost of integration, and any resulting bit coin transactions (that don't replace a more traditional form of payment) are upside.

There are plenty of dating apps with auto-renewing subscriptions.

I think a big problem with Apple is that the whole review process is a black box, because the documentation is thin, contrary, or non-existent. You basically have to submit and hope they accept your app and when it's rejected, the reasons are often arbitrary or contrary to previous submissions that were excepted.

I see, thanks for the data.

Rent in Argentina is crazy low in proportion to property pricing. As rent grows 20% year over year on contract, and inflation is higher, rent is lagging behind. I remember my absolute dollar value rent going down from 400U$S to 350U$S, in a 1 br 82m2-next to subway-first occupant appt.

Inflation really does a number on the economy.

And Im glad meal vouchers dissapeared in argentina, we had all sorts of them 8 years ago.

Regarding property prices in Uruguay, don't you have a reliable mortgage industry? Ours is ridiculously small, and inflation makes it risky and unreliable for both lenders and borrowers.

One small correction: the D machines weren't all smaller; there was the Dandelion (later sold as the Star), the Dolphin and the Dorado (which was a full rack, the size of a 32-bit CADR machine, and built of ECL logic). There were at least three different standard microcoded environments you could boot with, Interlisp-D, Smalltalk and Mesa. When I was at PARC if I worked late I could connect to a Dorado, but most of the time I used a Dolphin (plus my group had some Dandelions which ran some custom microcode). They could also run Alto microcode by the way.

I preferred the MIT lispm environment better because I grew up with it. For a while I had a job where I had both a dandelion and a 3600 in my office; later I had two 36xx machines, one with a color display.

They were pretty fast for their time. The late, hyper-dynamic window system was probably too heavyweight for its time, especially when later translated over X, but I generally used the simpler base window system because it was faster.

It was the most productive (in terms of amount of useful code generated per unit time) system I have ever used and I still miss it. The Interlisp D, though quite different to use (and in some ways better), is a close second.

> Free markets are the only way to avoid catastrophic booms and busts.

Actually, many people believe the opposite. Some even argue that high-frequency boom-bust cycles are beneficial, because the short duration of the bust makes it much easier to bear (everyone tries to get as much of the boom as they can, then suffer through the bust with minimal losses).

I, for one, would like to see websites that didn't install any tracking software. Specifically, I mean no Google metrics.

I can't tell if StorJ and MaidSafe are "scams" or not. I think they are. They're very handwavy about the exact algorithms they will use to solve the big problems (such as sybil attacks, etc). The StorJ "white paper" really does not explain much. Maidsafe recently made millions of dollars without having much to show for it, I get the feeling StorJ is the same thing. Pretty website, nice buzzwords, but no explanation of how it will work against greedy actors.

Now, here is another p2p storage-meets-bitcoin idea that actually has a very informative paper, Permacoin: http://cs.umd.edu/~amiller/permacoin.pdf

Compare the StorJ whitepaper to the above :)
Expedia accepts Coinbase, not Bitcoin. This is no different than accepting PayPal. Did you pay with PayPal balance, credit card, or bank account - it doesn't matter. You implement PayPal APIs and you receive dollars from PayPal. The rest is just speculation, but seems that price is dropping as "acceptance" like this can only lead to selling pressure if it ever gains any traction, of course. I'm really surprised all these merchants implementing Bitcoin for the PR, but confusing their checkout routine. The path to checkout should be as short as possible with as little decisions to be made along the way. Any distraction can lead to abandonment. Is the cheap PR all worth it? I personally doubt. It's obvious that the general public is not interested in Bitcoin and is, in fact, getting bored. I keep polling non-techie friends, the common theme is "Bitcoin is a scam". Even most tech people aren't much interested except the small share who invest in stocks, i.e. the speculator by nature.
Copyright restricts copying, it doesn't restrict similar, or even identical, expressions that are independently generated (a jury may see similarity as evidence of copying, so merely the theoretical possibility that a similar work was independently arrived at doesn't get you a free pass from liability, but similarity itself isn't restricted by copyright.)

So, no, the fact that a sequence of bytes occurs in a particular digital recording doesn't mean that the copyright owner of that recording "owns" that series of bytes. It means they own a specified set of rights in that particular recording.

> I should point out that the insurance costs here are surely low — although Uber encourages its uberX drivers to find “standard vehicle insurance” as opposed to livery insurance, the coverages required are nearly impossible to find, especially for someone with poor or no credit working 70 hours a week as a cab driver. Meanwhile, taxi insurance in NYC can run $7,000 – 10,000 per year...

For (1), how do you think it applies? The situation analyzed is taken from Uber's numbers, and is for an "average" driver that works 70 hours per week. If you're working 70 hours, you're not gaining a huge advantage from surge pricing.

For (2), again, this is a vehicle being used 70 hours per week, 40,000 miles per year. If you were looking at the case of a part-time driver it might not be appropriate to allocate all the expenses as business expenses, but in this case I think it is.

Hi Alupis! PixelBlock specifically goes after known tracking images and things that smell like them (ie. 1x1 images). It doesn't block all images.

You can get pretty good wifi pentesting functionality out of a Pineapple, currently retailing at $100.

https://wifipineapple.com/

I think for the particular purposes of this investigation, the Pineapple would have made a fine substitute for the PwnPlug R2.

Depending on your wifi card and drivers, it would also be possible to run something like Jasager or Karma on a laptop instead of a specialized wifi base station (although then you have to dedicate your laptop to the surveillance function instead of using it for your own regular laptoppy purposes).
Sure, didn't mean to imply that I thought this was a big advancement there (haven't looked at the options deep enough to tell, this included), just that the two concerns are different and YAGNI may apply to scale but not HA (though it can certainly apply to HA as well).
Interesting article. If I might "think out loud", and summarize:

Suppose I have decided that claim X is false. Now someone says, "Here is evidence for X." Then I am likely to think that there is deception involved: someone made something up, or misinterpreted something. Now suppose someone comes up with very strong evidence for X. I think: of course there is deception involved.

Thus, what is presumably strong evidence for X becomes, in my hands, strong evidence that either flawed reasoning or fraud is happening.

Also, while those coverages might be difficult-to-find-but-available now, that could change in a hurry. Once most insurance companies catch on to the fact that people are paying for regular insurance and then operating essentially a taxi service, they'll add clauses to their contracts specifically forbidding it, and charge something more in line with commercial taxi insurance. It's a lot like what we see with AirBnB, where as it caught on more and more, landlords started fighting back against tenants who were using it.
I wouldn't put too much weight on it...

> Why do people pay $1 million to own a cab? Because this is the aggregated value they estimate to be, based on the number of years they will operate the cab for(and the profit they will make from it). This is precisely why most cab owners in the NYC are immigrants who can barely speak English, because only they have the savings to own and operate a cab.

I find it extremely hard to believe that an immigrant with $1 million in savings (which practically makes someone rich in most parts of the world) would move to NYC and then decide to become a cab driver.

That reminds me of the missing mechanical equivalent of the capacitor, the inerter, which McLaren secretly began using on their formula one cars in 2005. But does this mean there's potentially another missing suspension component?

Predicting Exponential Growth with SQL

By replacing the distance function with:

let distance (a1 : int array) (a2 : int array) =
let open Array in
let len = length a1 in
let acc = ref 0 in
for i = 0 to len - 1 do
let v1 = unsafe_get a1 i in
let v2 = unsafe_get a2 i in
let d = v1 - v2 in
acc := !acc + d * d
done;
!acc

the OCaml goes 3 times faster. This is what would be produced if OCaml's inliner had triggered on the original definition of `distance`, so that is probably the main difference in the two language's performance. If you inline some of the other functions by hand (and tidy up some of the sillier parts of the OCaml code) it easily runs 4 times faster than the original.

> Oh? What is this great solution you have? The courts? That takes years, at which point the teacher is unemployed and may years later receive compensation. Good luck expecting that to go well.

Nah, it's an institutional problem; you'd solve it with slightly different rules about how schools are run. For instance, you could give principals more autonomy over hiring/firing teachers but make it harder to fire THEM, thereby reducing the ability of nitwit politicians to exert pressure to fire particular people. You could make more of the relevant intermediary jobs (like state superintendent) nonpartisan, and make being nonpartisan an explicit part of the job. You could add more transparency to hiring/firing decisions and leave it to the voters to punish politicians who do that sort of thing - if regular elections aren't enough disincentive, then add a petition-based recall process.

Or you could recognize that political sea changes at the local level don't happen often enough for this to be a significant problem, so we shouldn't worry about it until and unless it actually happens. Don't institute cures that are worse than the disease. (The fact that some district in Texas has this problem doesn't mean you need tenure everywhere in the country.)

Though the real solution is more student autonomy. Let parents decide which schools to send their kids to rather than arbitrarily assigning them to a specific one and the whole issue basically goes away. If parents don't like what's being taught to their kids, make it easy for them to go elsewhere or teach the kids at home and they don't NEED to get rid of bad teachers. (When people don't like what's served at a restaurant, they don't typically lobby to fire the cook, they just eat somewhere else! Because they CAN.)

Fundamentally, the purpose of a school system is to benefit the students, not the teachers. If you want to convince people tenure is a good idea, you need to make the case from that perspective - why it helps the students. Otherwise it just sounds like special pleading.
I've been working on an automated failover framework based on Zookeeper and ZFS for some time now.
