Ever wondered what dealers get cars for?

I had got my used car dealer license JUST to cut out the middle man and find out, even though it's expired now, I still have access to the ACTUAL SALES results for the dealer only auctions. Below is the link to the Dealer-Only auction post sales result in the bay area. Mark up is crazy!

Anyone fooling themselves and thinking "It'll be different this time," is in for disappointment. Of course Tumblr is the next Geocities. Yahoo is a public company that won't tolerate the freedom that Tumblr offers.
>>What I will give Yahoo the biggest credit they deserve is that THEY ARE making headlines and becoming a common topic of discussion.

Making headlines does not have to cost over a billion dollars. Hiring PR agencies is much cheaper.

My opinion however is along the same lines: at least Yahoo! Is looking like they have some sort of plan and are working (i.e. spending) towards them. This is probably better than the alternative, which is doing nothing.
Hmmm, perhaps if it was sort of tethered to the ocean floor using cables? Using a tethered base would also allow you to build in shallower water, as the flexibility would allow you to withstand some of the effects of a tsunami.
Do you think youtube's profits have paid for the initial purchase price and the losses it ran for the first few years?
Most people don't realize that they too have gluten issues.

I thought I didn't have any issues with gluten until I stopped eating it for a month. Now if I eat gluten I get a headache almost immediately afterwards.
Chuck, have you verified that the price is $15? because i heard it's mostly marketing and the real price is much higher.
Does anyone else find the push by the dealers to be incredibly anti-freemarket and anti-capitalistic? Strangely, many of the people who own the dealerships and are pushing on the side of the dealerships are conservatives, who in theory say they like supporting freedom, free markets, etc?
I like the concept, but how does it compare to using node + underscore?

Isn't the whole idea of JSON that it exactly serializes most JavaScript objects, and the "right way" to do stuff with it is to just use it like a normal object in your program?
It will sit in a VM.

Vagrant creates a VirtualBox (default) VM, uses chef / puppet (preferably) to set the environment up then you link the host's rails directory to a suitable location on the VM.

So yes, the environment is a VM, you can use "vagrant ssh" to access that VM easily enough but for coding you use your usual code directory on the host with your usual editor.

For information which functions as advertising to also be a candidate for fraud it must first assert something as fact.

There are many forms of advertisement which do not assert facts or even include language. An advertisement could simply consist of a graphical fictional portrayal of consumption or brand usage done in a glamorous light.

If something does not include a representation of facts, it does include a potential for fraud, and it would not make sense to regulate it as such solely on a principle of equivalence.
The answer is that currying reduces the cost of breaking apart and combining functions on their arguments, two things that are done frequently in functional programming.

Currying allows functions to be broken apart ("specialized") on certain arguments for virtually free because specialization and normal function application, in effect, become the same thing.

Consider Haskell's _map_ function for example:

map :: (a -> b) -> [a] -> b

You can specialize it into a function that adds one to every element in a list by simply applying it to its first argument:

incList = map (+1)

Currying also reduces the cost of combining functions by allowing any function that returns a function to have the returned function applied to any following arguments directly, without need of intervening syntax. For example, _flip_ modifies a function of two arguments (or more, thanks to currying) to receive its first two arguments in "flipped" order, the second first and the first second:

flip :: (a -> b -> c) -> (b -> a -> c)

To flip _map_'s arguments, I don't need to write

let flipMap = flip map in flipMap [1,2,3] (+1)

but, thanks to currying, can simply write

flip map [1,2,3] (+1)

The value of these tools, however, is not to be able to write complete calls like those in my examples above but to quickly assemble from simple functions the exact functions needed to solve the problems at hand, usually by feeding those functions into the higher-order functions found in libraries.

In sum, currying makes some of the most frequently done things in functional programming virtually free.
> They're rent-seekers, pure and simple, with no value add at all. Half the time they don't even have stock!

That's a major oversimplification. Car dealers can provide a lot of value to individuals looking to purchase a vehicle, both at the time of purchase and after the fact via test drives, financing, and discounts for future maintenance at their service centers. There are plenty of shady car salesmen that take advantage of vulnerable people, but that should not negate the benefits that many dealerships provide.

The stock issue is tricky, as many local dealers can't afford to carry a wide range of models and configurations. Stopping by the local dealership looking to buy a specific model vehicle same-day may result in disappointment. However, dealerships are very good about acquiring a vehicle that you are interested in purchasing. All you need to do is ask.

That being said, I agree with you that buying a car should be more similar to buying an iPad than it currently is. There are ludicrous laws that stifle innovation in the vehicle purchasing process, such as the Massachusetts Franchise law 93B[1] that prohibits manufacturers from owning dealerships. I think Tesla's vision[2] for first party dealerships and vehicle distribution is a step in the right direction.

Ask HN: Why do people worry about scaling before they actually scale?
I've asked countless entrepreneurs the following question: "Would you rather send 1000 generic emails to prospects to get 10 responses or send 10 personalized emails to get 1 response. Consistently the answer is the first option. This strikes me as arrogant and mathematically flawed, but the counterpoint is that it takes too much time to personalize marketing when attention needs to be paid to the product.

What are your thoughts? I feel like personalization cannot in fact scale, but in the early days it may be the one thing that actually helps you get bigger.
Xilinx' block diagram shows the FPGA having direct access to both the peripheral bus and the memory bus, including the cache coherency port, so I'd guess you can transfer data to the ARM cores fairly fast (as fast as you can get something from dram into L2 cache).

Now, while I agree with you that we better preserve civil rights, being stupid and forgetting to lock your front door certainly isn't a crime. However, opening said door and copying sensitive documents certainly is, no matter how dumb it was of the owner to not lock the door in the first place.

What I think we need is public disclosure of who had their data leaked and to make sure that the ToS can't cover "loosing" the data. Then at least we could have a class-action lawsuits and make sure that the incentives push companies towards securing their damn infrastructure instead of relying on insurance coverage and public ignorance.

>Is there such a "database", which:...?

As far as I know, no, all of them are lazy and load only what you query into the memory. But if your data fits in memory, it'll stay there, and subsequent queries will be faster.

Also, you can take the quotation marks from database, you have some quite generic requisites, most of them implement all requisits, except for the caching at startup one.
-I'm sure I can't just email these professors and say "hey, want to chat?"-

Why not? I am a barista with a high school dimploma and no interest in higher education, but I have emailed linguists and archaeologists to ask questions and discuss my independent research. In most cases I have heard back within 24 hours, in one, where the gentleman I reached out to had a 32 page CV, had held multiple chairs, and ran 2 institutions, I heard back from him within the hour. In each case I was received with enthusiasm and treated as a peer who just needed some questions answered.

It was a revelation for me, and I'm just some guy. I suggest that if you are active in both your field of study and academia, you should absolutely reach out to the experts in your field.

I kind of doubt it's Code Academy.

This article as of Jan 2013 said Udacity (which IMO is more rigorous than Code Academy) has only placed 20 people and Coursera only a 'handful'.

But the company (Coursera) matched only a handful of students in its months-long pilot
OMG this is so true. Disney and Nick were so bad that we cancelled cable for several years before eventually giving up when a good deal came along. :( We've regretted it. We limit how much they watch, but it doesn't matter. It isn't even attitude so much as just non-stop nonsense from both kids at the dinner table because that is what they watch. The shows aren't funny to begin with but imagine children trying to parrot the same behavior of the children in the shows without having any idea how to fully pull it off. It is HORRIBLE. Please make it stop. Our cable contract is coming up, but the fam is addicted again to the other shows we didn't get on air or via netflix.

So screwed.

"Car dealers can provide a lot of value to individuals looking to purchase a vehicle, both at the time of purchase and after the fact via test drives, financing, and discounts for future maintenance at their service center."

none of those things are exclusive to dealers for any reason other than the law requires it. a manufacturer-owned store could provide the same (or better) service in all cases. they add no value above and beyond what a first-party dealership would provide.
If you think they create value, then why not have the market validate that?

It's the same issue over and over. Just because you did work does not mean it is worth anything.

Oh man, a philosophical/ethical rabbit hole! Down we go...

> I mean, it is not ethical to willfully expose human to known dangerous drugs, yet if they take it wilfully by themselves or by mistake, it's a great source of data: for example, pharmacovigilence collects accidental use of drugs by pregnant mothers to guesstimate the toxicity on the fetus or the LD50 on humans)

The issue at hand isn't the subject's consent, I assume - the issue is our act of encouraging an individual to do something that might be harmful. Otherwise, there would be nothing wrong with performing studies on heroin use, as long as the appropriate warning labels were affixed. (I'm just assuming you're not a hard-core libertarian. If you are: just have a private company enforce the ban, and all will be well ;P )

I think, though, that it's also unethical to allow /others/ to knowingly encourage an individual to do something harmful. I recognize this is pretty controversial (if I were religious, I'd be a pain in the ass), but it means that if we are reasonably certain that item X is harmful, banning or restricting advertising is a must.

I also think it's ethically preferred to, where feasible act to discourage others (without coercion) from doing things harmful to themselves. Government- and charity-run nutrition programs, PSAs, etc.

That's our ethical dilemma, I guess, or at least mine. On the one hand, long-term scientific knowledge may be more rich and valuable if nothing is done. On the other, there is a moral imperative to take actions which might limit that long-term knowledge.

I'm inclined to assert, boldly and without factual basis, that there will be "enough" people who disregard the advertisements and PSAs, that scientists won't be much bothered by the missing data. Remember it's not like LSD; we're not banning the substance, just the encouragement. People smoke plenty of cigs, even though they're not advertised (and there's abundant negative advertising).

(By the way, I'm also very against coffee, having bad personal experiences with an individual who's behavior was/is noticeably negatively affected by the stuff. I'd support normalizing drug laws by lumping hyper-junk foods, caffeine, alcohol, cigs, pot, and other mildly harmful items of varying addictiveness into one big "restricted advertising" category, and using the taxes to send out occasional PSAs.)
And to think my first "real" computer had a 6502 inside it...
You should take a closer look at Xilinx's tech docs (there are a lot): http://www.xilinx.com/products/silicon-devices/soc/zynq-7000... - it uses ARM AMBA for interconnect.

FWIW, Parallella uses a very similar chip (ZYNQ7010 vs 7020) and lists the interconnect bandwidth as 2.4GB/s so I'd expect it'd be around there.
Who "ultimately pays" depends.

Surely there's at least a nominal rationale for these laws, even if the real reason is manipulation by special interests. Some kind of monopoly prevention? It seems a stretch.
I think we must include where you are growing as a factor of the discussion. The Indian consumer does not have a very high purchasing power. This means that the average Indian must focus on covering his/her basic needs, rather than buy luxury items. Your app falls manages to squeeze in by allowing Indians to send SMS without incurring into any cost. You are simply buying your way into their phones in order to get a fair amount of downloads in a short time. The issue with this tactic is that you can only spend so much. Time will come for you to stop paying for the SMS. By then, your funds will not increase. The rate at which you are spending them will only decrease by n amount. You cannot count on an UI to battle this issue. A pretty UI is nice, but doesn't matter if your users cannot use your app. I do reason that you will start advertising in order to level out the financials a bit. Something that wont really do a lot for you, due to the low purchase power of the local consumer. On the other hand, this seems like an app built to be acquihired. Something with which I have no issue. Companies engineered to be acquihired solve a problem, and are a fair way for another company to simply buy researched and developed products.

Anyhow, I'm just talking business. I wish your team good luck. I really want India to move forward in tech. This might help achieve that.
Preface: My son is 3 years old.

I let my kid choose his own entertainment. He'll more often than not either request the tablet or violent Donald Duck cartoons from the 50s (both of which we cap the duration to ~15 min). I believe that while curiosity is something to foster, we shouldn't force it upon our kids without providing them with alternative choices. Helping him develop an ability to discern pros and cons when making decisions along with negotiation skills will help round him out much more than trying to force him into a purely producer role.
Well it was a quote I got from the distributor. At a conference the guy talking about the chip gave me that price and I asked the distributor to verify it. They squirmed a bit but eventually said they would (also Arrow btw).

That said, there has apparently been a lot more interest in this chip than Xilinx expected and I got the impression they were worried they had under priced it. But some of the markets they are shooting for won't tolerate a higher price so my hope is that it will hold. At 10K units its only a $150K buy to get the 'good' price, one wonders if you could get enough interest in a kickstarter to meet that quantity goal.

Different? No. Its simply repeating past mistakes. Tumblr makes no financial sense. If they wanted to bring in talent to innovate, they could simply buy fifty bootstrapped startups for 5% of the Tumblr deal. That would net them the people they would have wanted. The only reason Tumblr is being bought is due to how Yahoo is showing off to the market. The CEO is simply trying to position Yahoo as bullish. Wall street will rejoice, their stock goes up (for a short time), and the shareholders rejoice. But this sort of thing does not last a long time.
I don't think so. It's just a bad parody of VC's.

Someone with the intellect and having developed disruptive technologies similar to some of what Tesla patented could still easily score investors. I think whoever did this was partially right-on but mostly just pissed at the way things are. The fact is, money doesn't grow on trees. There has to be a filter, and that filter isn't perfect.

I believe the 2.4GB/sec is the spec rate for this chip. Their demo board does three 1080p feeds mixed into a 1080p output which suggests it is pretty usable.

One of the key differences in this chip versus other architectures is that ARM system boots first and has some ability to do reconfiguration. (all of the key subsystems for the ARM core to boot are hard blocks.)

I don't hold out a lot of hope for open floorplanning tools from Xilinx but they do have a Linux toolchain so hopefully it will be possible to do native development.

Your biggest complaint seems to be that nobody is using sample sizes that are large enough to satisfy you. What is your justification for setting the bar so high? Just what kind of confidence levels are you looking for before you think a public health intervention is justified? 10 million people may be only 0.14% of the world population, but the total size of the world population has basically nothing to do with what constitutes a healthy diet for most people - human biology hasn't changed much in the past 300 years even though the population grew by a factor of 10. Huge sample sizes are only necessary if you're trying to study something rare (which is almost by definition not public health), or if the population is very inhomogeneous: an assumption you're making without supplying much evidence.

And the first two paragraphs of your comment read like a conspiracy nut's rant. It significantly lowers your credibility and quite justifies downvoting you for making assertions that contradict scientific consensus without providing any supporting evidence.
