The turbo is not irrelevant because it has a direct impact on the ratio of power delivery / fuel consumption due to the recaptured energy from exhaust gasses. The volumetric efficiency (ratio of cylinder pressure pre-compression to atmospheric pressure) of engines with turbo-chargers is almost always >1 while the volumetric efficiency of naturally aspirated engines is always (excluding rare high-performance vehicles in specific ranges of operation) <1.

I don't have time to do more thorough research right now, but the Ford Duratec 30 series of engines [1] is roughly comparable in both displacement and cylinder count and produces between 200 and 240 HP depending on configuration which puts this engine slightly ahead of normal engines from a performance perspective (smaller form factor and lighter).

Is there any apples to apples comparison that you can find that actually makes this development look substantially inferior? I get that you used a diesel because historically that gave the ICE an advantage but with modern diesel technology and forced induction they aren't the same animal.

Edit: changed 'pre-combustion' to 'pre-compression' for clarity on volumetric efficiency definition.

I think at this point, it's clear to me that Lyft is the one with poor ethics.

I would literally never have heard of Lyft without all of their accusations against Über. Über is trying to poach drivers; Über is getting our C-level guys to baldly incriminate themselves and then jump ship to Über; Über is stealing our cookies; waaaah waaah waaah Uber.

Honestly, I find it impossible to believe the Über team is both this B-movie-level evil, and stupid. It's really, really hard to believe that a COO of a successful startup wouldn't know how to copy documents that are on his OWN MACHINE (the private dropbox documents).

So, since Lyft obviously gets assloads of free publicity from all these accusations, and since I've never seen an actual court judgment against Über reported, I somewhat doubt that these are actually true, or at least not actually provable, since like others have said, if Lyft could successfully sue Über over any one of these things, the media would have even more of a field day than it's having now.

So okay. Über stole your drivers, your COO, shot your dog, made a mean face at you, whatever. Prove it in court. Until then I'm done with this bullshit. And I'll be happily using Über.

(The only thing that Über has really done that's unethical is be as brutally capitalist as they can, but I find that a difficult accusation to level against them since it's not like any other company is doing exactly the same thing. That's a systemic issue, not a local one.)

Edit: You know, if Lyft was running a black-hat PR campaign against Über, it'd be just like them to shill on HN. Thanks for the downvotes, Lyft.
What's absurd about it? Being hired to oversee Uber's overseas markets, it's hard to see what personal incentive he would have had to take all that data with him.

Not going to happen. Those "regulators" they decry so loudly? I'm sure they have plans to buy a few once they get big enough and use them to put barriers in place to put a stop to any competitors. Combine that with their size (and thus their ability to undercut any new competition), and I don't see anything but an Uber monopoly on the way.

I have a similar idea where the cores are put to work optimizing the produced binaries (profile-guided optimization, genetic algorithms, SAT solvers/theorem proving, etc). You could of course also do static analysis and all forms of testing (generative, property-based, unit, integration, performance, etc.).

Regarding point 1, java.jdbc can accept a variety of types of connection maps. The simplest scenario is you pass in a map that contains the connection information, and you get a new connection and transaction for each call. However, you can also pass in live connections/transactions that can be reused. The with-db-transaction form is one way to accomplish this. It's really pretty flexible.

What's perverse about the logic here? Alaskans say: we're okay with people using marijuana. And the Feds say: that's great, but we're not okay with it and as long as it involves interstate transportation or the coastal waters of the United States, we'll arrest you for it.

That's precisely the separation of state and federal power the founders envisioned.

I'd probably do that. Give the link to a few friends. It's pretty harmless, sort of an automatic snapchat. It'd definitely make me more conscious of when I'm being watched by my webcam, and I'd definitely want to have an opt-out when it was about to snap a picture.

Being aware of exploits and protecting against them comes with the territory. Luckily there are things like owasp.org to help developers keep up on web security. However, security is hard and it can't be done absent mindedly. There is no getting around that.

I like this statement. You could use it today.

"It is titled “The March of Intellect” and has the alternative title of “Lord how this world improves as we grow older.’ The main title is borrowed from a well-known phrase of the time, describing how the likes of Jeremy Bentham, Lord Brougham and others thought that educating the masses, and harnessing technology, would transform our world – for the better."

There are 7 billion people on the planet. Imagine if we educated everyone and then we could find a way for us to work on solving the important problems.
Same here... anyone got a mirror?
Unnamed defendants are common in litigation in the early stages. It's easier to amend the details of the complaint than to join additional parties to it after the case has started moving so if you have an expectation of edintifying more defendants you might as well mention that from the outset - otherwise you're liable to get derailed in obtuse procedural litigation.

So just to clarify, you think Lyft is making these accusations up for the sake of getting publicity?

And fabricating evidence to file in a lawsuit?
Here's how things will go. Über will continue steamrolling the country and locking down the market and subduing drivers into subjugation, then they will start regulatory and policy capture by corrupting politicians to write rules that keep them in power with as little effort as possible.

The reason Über is trying to crush competition, is that it knows they are currently still vulnerable for real competition to enter. Once they have dominated all the major metropolitan centers, they will know that they dominate to a point that significantly disincentivizes entry by real competition.
Pretty much, but the one Commcast was dropping in had an AC power feed, a set of lead acid battery boxes built into one side, and a moulded in space for holding about 40U of rack gear (telcom depth though so it looked like 12" not 40". Oh and a ladder in one side and a lockable lid. Very interesting kind of box.

This is really insightful.

I feel like a lot of the heavy drug use in our society comes from the fact that so few people get to get away from the nonsense. The promise of drugs is that your time between "real world mode" and detachment is 15 minutes instead of several days. Of course, most of these drugs have supply-integrity and dosage-certainty issues on account of being illegal, and are unpredictable at best and dangerous at worst. I don't intend to say "drugs are bad", because I think that research into the therapeutic potential of these compounds is 50 years behind where it should be, but most people don't know what they're doing and are using them irresponsibly.

I've noticed that as I've gotten older I'm better at dropping into a detached, almost Zen state... and ignoring the bullshit in "the real world". I've learned that you can't let yourself get sucked into the bullshit, even if you have to be at work. There's an almost sociopathic skill I've cultivated of playing the role without caring. I need to be the subordinate? Fine, I'm a paid actor. I've also worked to cultivate that ability to just focus on the moment, in order to make weekends more useful or effective. A long (15+ mile) bike ride can have that effect, or an outdoor meditation session, or just having a purring cat sleep on top of me. Even if I get just 30 seconds of that detachment, I consider it a success.
So basically e-commerce sites are charging me more?

For many of these criticisms, can't we strike the balance by designing rules based on an individual's proxy-power (ie the #people for which they proxy). For example:

re:1) For any individual exercising a proxy-power <10, all votes are explicitly private. For any individual exercising proxy-power >=10, all votes are explicitly public.

re:2) Monitoring, transparency, ethics rules, etc increase in proportion with proxy-power.

re:3) Budget and staffing increase in proportion with proxy-power.

Additionally: Proxy-power is capped (e.g. 0.5% of national population). If you try to assign proxy-power to someone who has met the cap, then the assignment is rejected.

"Elector selection" would be immediately subject to strong pressure from monied interests. The electors would need to be chosen from a pool (who gets in the pool?) and steps would need to be taken to prevent bribery (sequestration?).

Perhaps it worked better on your browser, but the content was so delayed that many times I scrolled past it before it decided to load.

Though there's no answer in the video, the classic demonstration of TMS (Transcranial Magnetic Stimulation) you'll find in an intro to brain imaging class is to trigger sections of brain containing the motor neurons. This creates involuntary movement in the muscles of your body, rather than any kind of information you would process willfully act upon. Given the mention of placing the TMS paddle on the opposite hemisphere of the brain from the subject's arm, it's plausible that they are actually just aiming at the motor neurons.
They're trying to slide a non-solicit into a confidentiality agreement. Hopefully the court will not accept this.
I think the fact that this boggles your mind says a lot more about your inability to understand other people's point of view than it says about the policies of the federal government (or the government of Alaska for that matter).
Uber completely ignored Philadelphia's telling them that launching uberX there is illegal, then let their own drivers get their personal vehicles impounded in a game of chicken.

Yet Lyft has the poor ethics. Right.

Considering there is serious civil harm arising from making up a lawsuit, do you have any evidence that Lyft's allegations are false or do you just flap your gums because you like Uber more? It never ceases to amaze me how people in all considerations can pick a side and stick to it, ignoring all data that doesn't fit their narrative. You like Uber more, nobody is begrudging you that. Turning your preference into calling Lyft unethical and the rest of your comment is, quite honestly, stupid.
While obviously overkill to run a small blog it certainly feels tempting. If could be efficiently automated surely it is worth a try.

However, what I'm more interested in is how Mirage works for, say, more practical tasks. It is quite some time already after it came up the first time, there were few blog posts about how to do this or that on Mirage OS, yet I never saw any real benchmarking. Is Mirage more/less/about-the-same effective in serving static content than nginx on Linux? Is it any worse/better than CloudFron static hosting for that purpose? How about real apps on multiple nodes using Mirage? How about it performing on ARM (as I understand that's still largely an experiment, but anyway, it is interesting enough topic to talk about)? Never saw an analysis of it by any actual security professional as well. Essentially speaking, I'm a bit upset that such an interesting project gathers somewhat less attention than, it feels to me, it should.

Wow, that video is fairly offensive if you look at the details.

- Video ostensibly made for blind people. Says: "Buy a windows phone." Writes: "Or any other smartphone."

- Video goes "65% of blind people are unemployed." Video suggests: "Buy an expensive smartphone, and a set of expensive special headphones."

- Video goes "65% of blind people are unemployed." Video promises the world, but only if one lives in a city with bluetooth beacons everywhere. ()

And at the end it makes clear why everything is so incongruous, they want to have everyone use this as a personal assistant.

Politically it kind of is a dichotomy. I see very little hope for Basic Income politically because the A) protestant work ethic is too deeply embedded in American culture and B) for many Americans the only outcome they would notice would be very high inflation.

I'm not against the very idea of it and if there were a referendum for it tomorrow I would almost certainly vote yes, but I honestly think that its basic presumptions are wrong:

* The the labor market today is allocating people to jobs efficiently.

* That as a society we don't have enough useful work for everybody to do today.

* That the government wouldn't efficiently allocate resources if it were to create jobs.

Treaty obligations do not have "almost constitutional standing". Treaty obligations have exactly the same standing as any law passed by Congress, whether they're constitutionally ratified (which is extremely rare), or congressional-executive (the common kind), in which the president signs a treaty that is completely non-binding on the US, but promises that Congress will enact legislation to fulfill its terms[0].

In either case, there is zero domestic legal consequence to deciding to ignore the treaty provisions. Technically a decision by the executive branch to violate treaty provisions is a violation of federal law, but there are no consequences. Obviously, if the US decides to violate a treaty agreement there may well be international consequences, including other nations' decisions to back out of the treaty, to refuse to trust the US in other negotiations or treaties, etc. All of that, of course, is exactly the same regardless of whether or not there is a formal process of derogation.

[0] There's a third form of treaty, "sole executive". That form is applicable when the treaty obligations are entirely within the scope of presidential power, such as Status Of Forces Agreements which the president executes in his role as Commander-In-Chief. Those, of course, have no legal standing at all except as lawful orders from the president to his employees.

We used to do nginx + gunicorn for our rest services, it was not responding well beyond a point (for a given ec2 instance). We replaced that with nginx + lua (openresty module), we saw almost 10x increase in response times. Would it make sense for us to invest in something like this and hope to see a significant performance gain? Lowering response times is not a big deal but being able to get those same response times on a lower priced instance would definitely help. We have no real C++ skills in the team but we could learn or hire.
