Yeah, my initial reaction was "name an auto manufacturer who isn't betting its future on small, turbocharged engines. It's pretty much a necessity, and much to the lament of automobile enthusiasts everywhere (who prefer a high-revving, naturally-aspirated engine).

Volvo does appear to be distinguishing themselves though. Namely in the fact that they're coming to market with an e-booster (electric turbo). There are plenty of dual-inlet turbocharged engines on the market, and Mercedes pushed the envelope with their M133 engine found in their performance oriented version of the CLA, but no one, that I'm aware of, has brought an e-booster to market. There was quite a bit of speculation that BMW would use one on their latest M3, but instead they went with a dual-turbo setup and some cool electronic wastegate management software that improves spool-up time.

The combo supercharger/turbochargers setup is crazy exciting though. The last car I can remember with that kind of setup was Lancia's group B rallye submission, the Delta S4. That car made, ostensibly, 480 HP from about 1.8L. In reality, the output was more in the area of 550 HP, and legend has it that engineers pushed the powerplant close to 1000 HP.

Every auto manufacturer is staring down a future of emissions and fuel economy standards that are going to require some fundamental shifts in the way cars are built and powered. Most manufacturers are moving in the direction of hybrid technology. BMW is betting the farm on mass-produced carbon fiber technology. Everyone has a strategy, and most involve lower displacement, forced-induction engines, often coupled with hybrid drivetrain components.
Correct. Victims bodies are tricked into generating large amounts of cells. This causes the hemorrhaging which is the ultimate cause of death.

Fun fact: The victim's body continues producing cells for several hours after death. In rare cases this (in conjunction with post-death bloating) causes the cadaver to "explode"

I thought there was a way to enter a namespace (googled this as I write the comment). Basically you have your shell and debug bits outside the container and make it appear as if it was inside it via nsenter [1]. I have not tested this, but will do that in a second. This might correct the situation you are thinking of.

That's not the case, Apple now hosts downloadable data (as of iOS 6 IIRC).
Andreessen makes some really excellent points in there, but there a few that just strike me as incorrect:

> Another classic Krugman rhetorical maneuver. According to Paul, keeping prices low is a sign of monopoly power, but of course he’d also say that keeping prices high would also be a sign of monopoly power.

Yeah its both. You can be a monopoly by having ridiculously high or low prices, mainly its really low then really high and if you think Amazon wouldnt raise everything by 100$ if it could, you're just wrong.

> It will startle every single business owner and CEO in the world to learn that negotiating with suppliers is now a business tactic that is “out of line”.

No negotiating is smart. Strong arming is wrong. Amazon is strong arming people not negotiating. They are playing the game where if you don't agree with what they are doing they are taking their toys and leaving. This causes economic harm to the company because of Amazon's volume to the point where the publishers have to use Amazon's terms which is monopolistic power.

> Another classic Krugman rhetorical maneuver. According to Paul, keeping prices low is a sign of monopoly power, but of course he’d also say that keeping prices high would also be a sign of monopoly power.

This seems silly. Krugman doesn't say that Amazon's low prices are a sign that they have monopoly power. He's saying that Amazon uses low prices to acquire or maintain ("reinforce") monopoly power ("dominance").
Don't compress then encrypt. It doesn't matter in this use case, but it matters very much in others. When attackers have chosen plaintext (which is virtually always), they can exploit compression to create a traffic-analytic side channel. This is the CRIME and BREACH attack on TLS, for instance.

Schneier, in Applied Cryptography (which: avoid) recommended compressing before encrypting. That was bad advice. Compression and encryption interact in treacherous ways. Get of out the habit of combining them.
This format is terrible for both usability (click click click click) and general coherence. A plain old fisking would be vastly superior.

Indeed, HBO's plans for direct subscribers[1] may be part of their strategy to be less dependent on the cable providers. When contracts expire and are up for renegotiation, HBO will have more leverage with Time Warner, Comcast. I think channels such as ESPN and HBO already do have quite a bit of leverage with cable providers but having their own direct link to consumers would give them even more.

To relate back to amazon, I'm guessing Jeff Bezos has to buy old HBO content at a loss to fill out the selections for Amazon Prime Video. That way, the $99 membership fee looks like a good value. Could amazon put a price squeeze on HBO? It doesn't look like it. Amazon needs HBO content more than HBO needs Amazon.

20 years ago, HBO didn't have these type of business options. If HBO didn't like Comcast terms, it would be unrealistic for HBO to start digging streets and laying new video cables to a million residential homes. With the internet, they don't have to. I'm not convinced that book publishers have no chess moves left to use.

Confirmational promotion may be true for the first leap into the management ladder, but not after that. Aspirational promotion makes sense for management, since it's really about social status rather than achievement anyway.

concern for other peoples' careers, ability to delegate, humility, emotional stability, ability to see multiple perspectives, commitment to Google and its values

You don't really see these among the people in power. Stack ranking? Secret "calibration scores"? Closed allocation? Blind allocation? People getting PIP'd for having 20% Time projects?

Programming by Voice: Staying Productive Without Harming Yourself
> This bill is like going to a restaurant and ordering the $20.00 dinner 'special' only to get a bill of $38.68, not counting the allowable taxes

That's a terrible example. In the US that's exactly how restaurants work.

In Europe if the meal deal says 20 euro it costs 20 euro (inc. taxes and tips are legitimately optional). In the US if it says $20 it costs $20 + 5% hidden tax + mandatory tip (15-20%). So in the US a $20 meal costs $24.15 (15% tip which I'm told is the minimum).

That's the way the entire US society is set up top to bottom. Hidden fees, surcharges, and required "tips" on every single thing. You cannot even use an ATM without being hit for a $3 fee now.

Yet whenever anyone brings this up everyone flocks to defend the practice, like people who want an inclusive price are bonkers! Sorry but American pricing is screwed up, stuff like this is the normal rather than the exception unfortunately.

Speaking of "really is just C with some syntactic sugar" — so, is there really a point in putting effort in learning (and using) Cython over C? Reading the code in the article I wasn't completely sure if I should feel like it is "cool" or "confusing". Not that there was something I actually dislike, but it's somewhat awkward to see C written like Python, so I can't "rate" it myself right away.
I've been thinking about using a simpler browser for reading simple documents. The motivation is to have a sort of "minimalism", as in using simpler programs to do simple things, and not get easily distracted by all the bells and whistles in a more complex application (like for example Firefox). This, I think, would be aided by using a simpler browser that could for example be run in a virtual terminal for reading things like documentation, in the context of developing where I will need a terminal (and maybe also a graphical text editor), anyway. So then there is less context-switching, presumably.

I am not someone who tries to do everything within Emacs[0] (yet?), but this seems like something that might be able to fit nicely with this kind of style, since I can restrict myself to only using Emacs and terminals for developing and reading online documentation. Does anyone enjoy working/developing like this?

[0] Yes, I see the slight contradiction in wanting to do things in simpler software, and then suggesting doing those simpler things within Emacs. :P
> engine still burns fossil fuels

It does, it's just centralised and called a power station... it's incredibly naive to think a Telsa isn't contributing to burning fossil fuels - it's just not in front of your face.

Also I am not sure whether any modern power grid in the world could cope if even 10% of cars became PHEV, imagine the spike when everyone got home and plugged in their car - would be like a "TV Pickup[0]" on steriods, they usually cover these with short term solutions such as hydro pump but this wouldn't run the time it takes to charge a car.

I think you're grossly underestimating the number of people that an electric car is a complete non-starter for.

It's great that electric cars exist now (and maybe someday in the future I'd even be interesting in buying one once there existed infrastructure that made it feasible), but I think your timeline for the obsolescence of internal combustion engines is laughable.
Also, the exact question you're trying to answer makes a difference. If the question is, "Is this a picture of a bird?" where "of a bird" means that the primary focus of the picture is a single bird, then your picture should return "No". That's different than, "Are there one or more birds in this picture?"

I'm not sure which question Flickr's team actually seeks to answer here.

They are related in that they are both probabilistic programming languages, but the similarities stop there.

First, infer.net is a DSEL of C# implemented as a library, while this is a new language. More substantially, infer.net is designed to use variational inference, which limits the class of graphical models that can be supported, while R2 seems to be based on sampling hence has no limits on the models it can represent. A more similar approach would be Church (http://projects.csail.mit.edu/church/wiki/Church), a probabilistic language based on Scheme.

Of course, the downside of sampling is that inference is orders of magnitude slower, and there's no principled way to know when it converges, that's why many people prefer variational inference.
We also hit this - it was a bug, and was fixed within a couple days. They are now rolling this out intentionally on Feb 1.

This is a challenge for us because we use a large 3rd party library (WebRTC) that has a bunch of armv7 assembly in it, but Feb 1 should be enough time to get it sorted.

The argument being made against the picobrew is that it takes away exactly the thing a significant portion of the home brewing community enjoys:

There's a depth and risk of failure to brewing that is simply not there with baking bread.

Yes, as long as the features remain reliable. But sometimes, though rarely, an upgrades retires an API or worse, changes a default behavior. I guess that you have thought about that, but that is what I meant with my original question... Sometimes you have to choose between feature stability and newer versions (for new features or, more importantly, bugfixes). How will you handle that balance ? What guarantees does the customer gets either way ? Doesn't making it explicit to the customer comes in conflict with hiding the gritty details of database server operations ?
I've only heard about 5s supporting Apple Pay with Apple Watch.
It seems an odd choice to say three turbochargers in an article that references superchargers when it reads as an electric supercharger plus sequential turbos.

Personally, I'd much rather see advancement / acceptance of self-drivers even if limited to highways than incremental improvements to traditional cars.

The main, perhaps only reason I really care about response and acceleration is the generally selfish, adversarial behavior of human drivers.

The contrast between the same daily drive in a 4-cyl compact and torquey V8 is stark. In the former, every lane change has to come with permission - that drivers are often unwilling to give. In the latter, I'm in complete control.

I'd much rather the third possibility - to know we're all on autopilot gliding along at a safe, predictable rate to our destinations.
I can't imagine that this stuff is legal - the NYT has paid Krugman to write this, and Genious is just copying the text and adding a few (to my mind inane) links and comments. It all seems very shady..

Wow. Talk about an advertisement for the ineffectiveness of annotations. I've got comments from multiple different authors on here simultaneously - who are all these people? I was interested in Marc's annotations - talk about bait and switch.

For complex subjects, this is a great example of why single-author critiques are best, so you can follow a single person's train of thought and their logical conclusions (or errors).

This particular debate strikes me as pretty juvenile in both directions - by Krugman, and his critics. Marc gets "closest to the pin" for me when he says "if Amazon was a monopoly, it would be raising prices." Of course, that's not to say any big company can't overplay its leverage in "supplier negotiations" and this is surely something worth discussing. Marc is also right that the judgment here is a lot more nuanced than standard oil owning 60% of the market.

Going a little deeper on the Hachette dust-up, it's really interesting that the chattering classes never took much of an axe to Amazon's reputation until it tread on their turf - book publishing! All the waylaid mom-and-pop stores were just hicks who had it coming. Protecting the fat advances paid to big name authors - that is sacrosanct - part of the rewards that go with public life these days, and part of the corruption IMHO.

I will end with Glazer's beginning - "Krugman nearly always gets it right...but this is very wrong." I find that this Amazon critique is easier to contextualize if you shift that understanding - Krugman is frequently wrong about many things, and this Amazon article fits neatly with that overall trend.

A simpler explanation for Amazon offering 2 - 3 day shipping for Paul Ryan's book is that Amazon purposely avoided aggravating an influential Congressman. This is a much lesser accusation than systematically favoring books of a certain political bias with quicker shipping times.

They just look like BMW took some inspiration from Fisher-Price. It screams "we don't take this car seriously". Teslas look good, like they're /meant to sell/ rather than just making an eco-statement. It might be a nice car in the practical sense but it's not a serious entry in the EV space. The only electric cars that matter is Tesla Model S and Nissan Leaf, period.
Facebook’s Jan Koum Apologizes for Past Restraining Order
How can you possibly compress encrypted data? An ideal cipher should produce output indistinguishable from randomness, which is inherently difficult (read: near impossible) to compress.

This is the similar project built on top of compressive sensing:

As soon as a brand new Tesla costs between $20-30K (which is pretty typical for a new family car) you'll have a point. Right now they MIGHT be releasing a $36K car MAYBE at some unspecific point in the future.

That also entirely ignores the range problems. Even with charging stations every few towns, you'll still have to stop for 30 minutes to "supercharge." That is as opposed to 5 minutes for petrol or diesel.
The article is kind of confusing. At one point, they say:

"The 2016 XC90 (on sale early next year) is the first of this new generation of Volvos. It’s powered by a 2.0-liter four-cylinder engine with a turbocharger and a supercharger. (While the turbo works best when the engine’s already going, a supercharger forces in air with power generated by the engine itself, so increased boost is available from idle.) The supercharger runs from idle to 3,500 RPM. Above that, an integrated clutch disengages the supercharger, allowing the turbocharger to take over."

Based ont his paragraph, it sounds like a traditional supercharger that works up to 3,500 RPM. Later on though, we get this bit:

"We’ve seen plenty of twin-turbos before. Volvo’s innovation is adding a third—third!—turbo. But this one doesn’t charge the engine. It charges the other turbos. It’s electric, hence the name “e-booster,” and sends air into the two conventional turbos to improve their performance below 3,300 RPM, filling out the torque curve and eliminating that pesky lag problem."

Now we have an e-booster referred to as a third turbo, which runs up to 3,300 RPM.

So, the confusion is warranted. The article isn't entirely clear on whether these are two engine options, or a single engine with inconsistent details.
That puzzles me. Why would one want to get into Facebook? Do they pay that well?

Cython is used to write extension modules for Python. If that is something you want to do, it is better than plain C because the code is more compact and less error prone because some things are taken care of behind the scenes. The point of using Cython is to combine the best of both worlds (Python and C).
TL;DR: -Top employees use top large corporations as springboards to their careers rather than as 30-year destinations, a marked change from the past.

The author didn't provide evidence for much of what she claimed, and did not build towards a conclusion. More, the above themes did not seem like new news to me. Also, the first two themes did not clearly related to the third.

Brilliant is a very bold word -- I've met a number of people who work (or who have previously worked) at Google and Facebook that are a long way from brilliant.

But the point is valid in that we have an industry where every company likes to posture and interview as if they are hiring the top 1% of programmers only to turn around and give them jobs that a well-trained monkey could almost do.
A "twincharger" (super+turbo) is notable for different reasons than you suggest. A turbo can hit stupid peak power numbers all by itself.

The addition of the supercharger to the turbo dramatically improves low RPM power and often peak torque as well. In doing so, it also makes a larger turbo more practical as it reduces the problem of "turbo lag" (wherein a large turbo paired with a small engine doesn't engage until very high RPM)

Race engines, of course, often aren't quite as worried about turbo lag because many cars spend their entire time at peak power.
