You don't need a Thermodynamics Ph.D. to understand this. Moreover the normal (gas) cars have the same behavior. So it's annoying that a car expert don't know it.

You get the best mpg at a constant speed of ~50mph, and it's better with the cruise control because it reduce the times that you need to accelerate or decelerate.

If you go too fast, the mpg drops because you need more fuel to compensate the additional resistance.

If you accelerate and brake (for example in a city), the mpg drops because you need more fuel to accelerate and when you brake the energy goes away as heat.

The advantage of the regenerations brakes is that some of the energy that is "lost" as heat braking is stored and used again to accelerate. This is not magic. It doesn't make braking lossless, it only recycles part of the energy so accelerating and braking is not so bad (it's only bad). This is well known for the electric and hybrid cars (I think that there are some tries to do something like this for gas cars, perhaps store the energy mechanically, I'm not sure.)

I think that the recommendation was (paraphrase) "If you are going to drive inside a city, it's better to turn off the cruise control."

The articles that he understood something like (paraphrase) "It's better to drive inside a city than in a highway with cruise control."

It's very surprising that a car expert can understood this so totally wrong that it look like it was a willfully misunderstandment.

Enterprise America is very different from small company America, that is why I made mention of talent retention, it is a tangential but related conversation but it does not really fit in the space of what the article is lamenting. I have worked in both, I prefer small business America because their is a stronger focus on quality and individualism but sometimes the enterprise is where the bills are paid. Those of us not in the valley have to split our times between what we would like to do and lucrative contracts that the likes of companies like IBM provide.

The interesting part is it has created a culture of something akin to special forces teams, where groups of caravan style freelancers who have worked together in ad-hoc groups tend to come together on contracts many who have worked together many times over the years and yet other who have worked with others that you know. So sometimes you will go into a contract with guys that you don't know, but you know of them so the relationship develops quickly because it is like you know them. They are very talented individuals, but it's almost a mercenary mentality. They do quality work, but it is almost a robotic professionalism.

As I recall, the control problems were in the boundary layer, when the ground effect benefits waned, but before the engines pushed it into 'flight'-proper.

That said, it also sounded like it was capable of 'flight'-proper for the same reason that just about any-shaped craft is capable of flight when strapped to engines of such outsize mass and power.
> it's just important to understand than Rails doesn't get any special treatment on a PaaS done correctly, so it's important to come up with a generic solution.

Its kind of weird to describe not optimizing the entire platform provided to apps as "PaaS done correctly". Making a PaaS more generic has a certain kind of value in terms of broadening the audience and enabling heterogenous systems to be implemented on it, but if you are doing that by sacrificing the optimization of the individual application platforms available, you are losing some of what makes a PaaS valuable as opposed to roll-your-own platform support on top of a generic IaaS.

Its especially problematic to say that worsening support for the main existing app framework in use on an establish PaaS and giving existing customers orders of magnitude less value for their money is doing something right.

> I think part of the solution would be customizable option

That's probably a good idea, though the default for existing apps should not have changed, especially without clear up-front notice.

> But apps are increasingly unlike a checkout line.

Existing apps are, for the most part, exactly as much like a checkout line as they were before the unannounced change.

To be fair the German's lost the war to two separate things, neither of which was due to anything that happened on the battlefield directly.

Hitler's move to bomb cities in Britian cost them London. His decision to change his objectives half way through the Russian campaign cost them Moscow (although you could argue invading Russia at all was dumb, the German army was still poised to overcome this, amazingly.

As for Japan, I think your point stands.

nope, the point is that the machine won't boot a compromised OS without the user knowing. the scenario is that the bootloader is compromised by some process other than the user turning it off.

we're not trying to protect computers from the people that own them. security isn't about stopping people from having full control of their devices, it's about stopping processes from having control that the owners don't allow.
you have to admit the status-quo has changed with regards to public understanding of how to deal with "terrorists have taken over my airplane." before 9/11 it was a scary affair but basically was reduced to the same equation as a mugging: let them do what they want, it will all be over soon, it's not worth being a hero over. not the case anymore, quite the opposite.

They show two versions in the diagram. One has conventional jet engines inside the saucer, but the other one has parts of the whole saucer spinning so the fuselage works like an engine. They have compressor blades, burners and turbine blades inside.

That is interesting, and I haven't run into anyone pointing out this distinction or doing any analysis on it. I don't know what limits the aerodynamics but potentially you could get really high amounts of thrust, something more comparable to a helicopter than a Harrier. You could run into big problems with gyroscopic effects as well, maybe you would need two "spools" that counter rotate.
Exactly! It's a very cynical view of the media and unfortunately one I encounter too often among tech vendors. This statement makes everything else seem like sour grapes, regardless of the facts of the matter.
> A true testament to his disinginuity is his pretending to think that stop and go is more efficient than highway mileage. He has no place as an energy reporter unless acting as a shill.

Why is everyone here conflating gas-powered machines with EVs? There's a reason Tesla recommended he slow down and go through a city. There's a reason the Prius has a higher mileage rating for city driving than highway driving.

The reason is that driving faster requires proportionally more energy. It's always been that simple. The reason cities have historical given poor mileage is because of energy wastage from idling and from braking, both of which many EVs (incl. Tesla's) can minimize the energy loss from.

This is required by federal law. Contractors are required to reside in the US or be a US citizen. There is no outsourcing in the federal government for obvious security, quality, and political reasons. It is one of the reasons that while many large tech companies are/were laying off gobs of people in their US divisions the survivors were notably for the most part working on government contracts.

No, no, no. There is no such thing as journalistic embellishment. That's not okay, and certainly not for a journalist at The New York Times of all places.

I'm a journalist, and I expected what was written by Broder to be accurate, not embellished. This isn't Top Gear. There is no story to tell, just the truth.
Secure boot doesn't offer any practical security.

Most attacks are just social engineering, spyware and daemons for DDoS attacking. Basically all stuff that can be run from user space. There's no real advantage in writing rootkits in our current climate as it's significantly more complicated and not nearly as profitable.

The cynical side of me thinks secure booting was intentionally developed to lock users into their respective platforms and only later sold as a security mechanism to avoid a massive outcry (a la the "terrorism" excuses that Apple used to argue against jailbreaking).
Stop and go may be inefficient since it takes a lot of energy to get a still car moving. Regenerative braking can't capture all of the energy lost when decelerating. That said, city driving may still be more efficient than highway in an electric vehicle. Note that the speed which maximizes fuel efficiency for most vehicles is around 30mph. So driving 60 on the highway isn't as good as driving consistently 30mph. Depending on how much speed deviates from 30mph and how good the regenerative braking is, fuel efficiency could plausibly be higher at 30mph with some stop and go than a consistent 60mph.

Of course, I imagine Manhattan is not the place to test this hypothesis...

>Does Windows 8 not run on UEFI systems without Secure Boot enabled?

It runs without any issues on machines with secure boot disabled.

>Or is this fix just due to pre-installed OEM Windows 8 configurations with Secure Boot enabled?

Yes, although the user can disable secure boot, it's an additional step and also reduces the security of their Windows 8 boot (if they're still using it).
>What better way to demonstrate Supercharger tech than in a real world scenario.

My point is that Musk is saying that like he didn't write the story he was supposed to, which was about 'future advancements in our Supercharger technology'. But clearly they knew what the eventual point of the story was, since they lent a car and provided support. So why bring up the original intent of the story?

Yeah, it looks like the basic display is range plus a basic bar graph. So when Musk is quoting percentages, that's not what the driver sees.
Yup. Musk didn't explain the biggest issue here, which was the drop in mileage overnight. There has to be a perfectly reasonable explanation, but Tesla doesn't seem willing to explain it.

The .6 mile circle in front of the charging station is completely irrelevant, because it's in front of a freaking charger, which is the best place to see if 0 is actually 0.

There's actually a route to the charger from the highway(if you miss a few turns) that's about... .6 of a mile.

We broadly agree.

Science is more than "being objective". My "test" vs "prove" business was about devising tests that you expect would be most informative, not just accepting the results.

For instance, I could test if an apple really falls when I drop it. But I'm know it will, and I'm quite certain I will learn nothing from such a test. Therefore, I won't perform it in the first place.

I reckon objectivity is a good start, though.

Also, I did say that a biased journalist should not be allowed to conduct reviews. That indeed prove we don't live in an ideal world. Unless you made a deeper point, and asserted that such journalists actually should be able to operate precisely because of non-ideal aspects of our world?

WorkSimple is Shutting Down
I received this email from them on Monday; it's definitely a shame. Their website said they have 4000+ customers, and Crunchbase listed a $250 Series A in December.

Good luck to the WorkSimple team for the future.

==========================================================

After exhausting all options, we are forced to close WorkSimple. We're devastated to have to shut down the service, but unfortunately due to capital constraints, we have no choice.

It has been an incredible journey and we're heartbroken not to be able to continue on. We've created the Social Performance space with you and demonstrated that there is significant demand for this type of service, but not yet enough demand to support what the company needs.

We have an incredible community of customers and partners across the globe who have helped shift how we work together. We believe this will continue in the marketplace.

What about the app?

We'll keep the platform running through February after which we will have to shut it down; however, we recommend you begin taking data off the application as soon as possible.

The simplest way to get goal data is via exports in the reporting section of the application. If you are a paying customer and need exports beyond what reporting provides, please email help.

Finally…

We're grateful you chose WorkSimple, and we're very sorry to have let you down.

Sincereley,

>"They were, in no way, behaving like any half-ways rational person would"

I know, right? No rational person would put the cruise on 60, sometimes do 80, and expect the cabin temperature to be a balmy 75 degrees.

Broder's article was a hack job. That's obvious. But I can't come to terms with how a rational person would want to stop every 3 hours to charge a car for an hour. Get yourself a small turbo-diesel and you're doing this trip in probably half the time, thanks to no charging and setting the cruise at whatever you want. Oh, and you can play whatever music and set the cabin temperature to whatever you'd like. And it's 1/5th the price.

I'm not surprised that the Times wrote a shitty article. I am surprised at how bad the Tesla looks as a daily driver.
It is indeed very dangerous to call one's self "rational" or "rational thinking', but I'd say that's exactly why they call themselves "less wrong."
