I got a mail from a company doing power9 boards (something eagle ??). A bit pricey but it seems worth it if you have such needs.
I've seen a couple of oblique references to this in other comments, but I'll go a little deeper: if you want to truly understand the prisoner's dilemma scenario and how it relates to human, or more generally, animal behavior, there is incredible coverage of the topic in Richard Dawkins' The Selfish Gene. He pioneered the idea of running PD "competitions" in an attempt to discover the best evolutionary strategy for PD, and how these strategies might predict large-scale behavior in animal populations. Each competitor (other scientists and researchers) submitted a strategy for handling the PD in the form of written code that could face off against other strategies. Each round of competition consisted of thousands of iterations of the game. Some strategies were simple and some were incredibly complex. Across two competitions, the second with 60 competing strategies, the simple and "non-cynical" strategy called tit-for-tat won handily. (Tit-for-tat is mentioned briefly in the original article without any explanation.) This is the strategy:

- Unless provoked, the agent will always cooperate.

- If provoked, the agent will retaliate.

- The agent is quick to forgive.

- The agent must have a good chance of competing against the opponent more than once.

The fact that this strategy was a consistent winner in his competitions has led Dawkins to argue that "nice guys finish first" and could be a partial explanation for certain forms of so-called "altruistic" animal behavior -- behavior that seemingly gives no benefit to the altruist, except for the fact that too may benefit when it is their turn to be helped.

Really since 1997 at low speeds.

Toyota has put a small battery and electric motor in their cars for 20 years now capable of propelling the vehicle at low speeds.

But if you're trying to build an actual electric vehicle, you don't want a small battery as that puts you on the worst part of the discharge rate and battery life curve. A larger battery in the same vehicle reduces the "C" rate and is much kinder on the battery plus gives you much more power to work with and ability to handle a much higher charge rate.

Big battery wins, long-term. Small battery is a false economy except on hybrids.

I think the lack of appreciation of this (and lack of availability of inexpensive batteries) has hampered a lot of carmakers. Address that (super cheap batteries so you can put a 500 mile battery in if you want), and virtually every "problem" with electric cars goes away or is dramatically reduced.
Hell you can do an apples to apples comparison. Honda said the same thing about both autonomous driving and EV. They are waaaaaaay behind the curve and are hoping that FUD can keep people from buying their competitor's offerings.
Nope. And I'm suspicious too. The weird thing is, this was some off-hand anecdote about some other topic, for which organ harvesting wasn't even the subject. Anyway, whenever organs are harvested from a patient who would have lived, it's not like we'd know. Assuming you don't believe the rate this happens is zero, I'm not sure we have substantially different expectations of how often it does.
According to a quick google, noticing that other cars are pulling in/slowing down usually works if they can't see the emergency vehicle. Still, it's not "perfect", but then Hearing drivers are far from perfect either, and there's plenty of failsafes before an accident happens.
Come to think of it, I can't remember the last time I typed a password in an app, after initial setup.

As for creating a contracting agency, it becomes about sales and marketing. You can market yourself as a premium dev shop if you find other senior programmers to work with you. You have to get good at reaching out to companies and offering them your services. Upwork isn't a good place for that imo, but you could think of Upwork as just another channel for your sales funnel.

I'd love to play around with this dataset! It certainly seems richer than MNIST, and would most likely force the network to extract more features.

But just like MNIST, it seems to lack variety in the positioning of the important elements, they are all centered which means that they don't train the network in being translation invariant. I presume this issue can be tackled with data augmentation techniques like applying affine transformations.
Out of curiosity, I looked up who was Secretary of the Navy in 2003. It was tumultuous year, with 3 different people holding the office. Only one of them had any military experience (in the Air Force).

Gordon R. England held the office at the beginning of the year and was re-instated at the end of the year. He held the office for about 4 years total. He had no Navy experience. His background was in the defense industry. What a crock.
It's a classic speculative bubble. People are making bets to position themselves for a situation where Bitcoin will be worth a lot in the future, but the valuation is untethered from any intrinsic value.

The surge becomes self-sustaining, in that as news stories of easy wealth spread and more speculators bundle into the market, it fuels more demand from new participants looking to get rich quick. This is not sustainable in the long run, and as soon as the crowd gets spooked all the dumb money will bail out very quickly, leading to a very fast crash.

The Gladwell book "The Tipping Point" is a good read about how ideas and fads take hold in societies. It's more a function of the way information spreads than about any secret knowledge about Bitcoin. Nobody can predict the future, but Bitcoin speculation is an attempt to gamble on it.

There's an investment adage that's something like "When your barista's telling you to invest in something, it's time to get out". Have had a number of non-tech/non-finance friends ask about how to invest money into Bitcoin lately, which is a signal to me that Bitcoin is becoming dangerously overheated.

Take a look at http://static4.businessinsider.com/image/515b40886bb3f7bd490... from the South China Seas bubble in the 18th Century. The first half of that curve look familiar? Guessing we will see a lot of Newtons in the not so distant future...

How would you go about generating such dataset?

1. Scrape images and store as png

2. Downscale to 28px

3. Convert each image to grayscale

4. Convert to matrices and add label (additional row?)

5. Normalize to have matrices of 1 and 0 for faster computation

6. Vectorize said matrices

7. Concatenate into one big vector

I plan on working on my first ML side project and I would love to gain some insights from HN.
I think Musk realizes that electric cars will be a commodity which will lead to razor-thin margins. The one thing that's not yet a commodity, and will not be for a while, is lithum-ion battery tech which is why they are building the gigafactory to cement their place as near sole supplier to the rest of the industry when they eventually catch up with selling all-electric drive trains.
AMT is a piece of software that runs on the Management Engine. vPro-enabled platforms are the ones aimed at business laptops and workstations, not consumer stuff. It's important to make the distinction because people can check, find that their machine doesn't have the VNC functionality and then assume that they don't have anything to worry about as far as the ME goes, which is a false sense of security.
I never understood that - why do people brag about cheating the tax man? I have to make up the difference, in either (very slightly) reduced services or higher taxes.

Facebook burnt through $700M if I recall correctly. Back then this was unheard of. Though, most of it was to support their explosive organic growth while ad revenue was catching up.

Google made money almost from the start I think.

Reddit has been losing money since its inception.
Wikipedia is misleading again. Notice that there are no sources for any of the claims made about several of the softwares, to check the article against.

qmail does not, strictly speaking, even support SMTP over TCP. This is because it relies upon UCSPI tools to do the actual transport layer setup. UCSPI-TCP does the TCP part for qmail. And one can equally well layer it over UCSPI-SSL.

People did. Erwin Hoffmann, one of the UCSPI-SSL authors, even wrote a lengthy article on the subject of SMTP over TSL/SSL with qmail.

It is quite a logical thing though. 90% full autonomous driving is not. And the first 90% of autonomous driving could very well be within reach of our software capabilities at the moment (or maybe 80%, but it will not change the discussion much).

You can only release it when you reach 100%, and if that last fraction takes the next 50 years then we really are not even close.

Okay sure. but...

How is 10-20 peoples worth of coronor time worldwide an appreciable number for taxpayers. Furthermore is it even remotely comparable to the cost of trying to enforce a ban, which would presumably also be funded by tax payers.

My point is more that you've at least thought about it a little, unlike the OP of this thread.
Does it? Revenue is != profit though.

This is where it bothers me. Startups start out by taking a share of the enterprise companies lunch by doing things that enterprise companies can't because of the structures they built.

At some point when startups get successful they flip a switch a switch and try to become more enterprisy. They might get a "real" CEO, one of the big performance metrics becomes by how many hundred people you can grow the company per year and at some point if they make this transition successfully the company will start to stagnate. Back in the days when I went to some Erlang user group I was complaining about how I could solve a problem and rather than solving the problem the guy wanted to grow the engineering team to 20 people(from 5) some government contractor said that I don't get how the system works. You think that solving the problem is the key performance metric, but the actual metric is how many people the manager manages.

One of the comments I saw below is true though. They grow the numbers and then they don't have proper management to fill the gaps. But what's proper management to begin with?

If they "invest" in their people they will promote their earliest employees to director of xyz. Congrats, now some random crappy junior javascript developer is now your Director of Engineering and it will be legitimized by the $10000 Leadership 1 weekend course he got at Stanford. He will do 1 on 1s with you and try to talk about your future.

But here's the problem though. Where do you get good management? Anecdotal evidence, I once sat at a dinner table and next to me was some old school business guy with his friend, a senior management guy at another company who recently got fired, saying that the worst thing you can do is hire middle management that is weaker than you. He will always try to keep the lower tier below himself. I'm supposedly in a leadership position in my company, yet the thing that no one ever wants to hear in upper and mid management is fixing issues.

Ironically I recently did a PMP certification to see what the fuss is all about(granted, it's not really a management certificate). Nothing I saw in that formal guidebook aligns with what I've seen in real life. So if you can't get good management from other "enterprise" companies, and you can't get good management from your early employees and you can't get it from training, then why strive for that model to begin with?

It seems like the only rational explanation for all of that is to pump up to numbers so you can aim for a nice exit on the ipo.
Unfortunately you can't augment a level 5 self-driving car with human resources in an analogous way.
I especially like the way the following video explains the long-term vision of why Bitcoin is valuable. Once you understand the long-term vision, and how Bitcoin's fate is still very much up-in-the-air in some respects and still subject to a lot of speculation and possible government interference, it's not hard to understand that such large short-term upsides and downsides are to be expected. The speaker is Andreas Antonopoulos, a particularly eloquent speaker (IMHO) about all things bitcoin: https://youtu.be/ONvg9SbauMg
My question in that vein is more of "why will this succeed, where beanshell failed?"

That is, I had REPL style environments for java a long time ago. And literally nobody used it. I can see arguments for having the REPL being in actual Java instead of a shell subset. But, Java has a long way to go from bootstrapping something in a repl and automatically saving it to something that will work as a normal entry point. (Though, again, even JRebel has existed for a long time now.)
You are right that in principle an image based system should be able to produce a better tool for dealing with that environment than is possible with a text based system.

However no image based system is poised to take over the world. And I'm willing to bet my salary that none will ever have sufficient mind share to do so. Programmers switch languages, environments and operating systems. When you add switching tooling to the learning curve, you've just created a barrier to entry to the environment, and programmers are going to spend time learning something that is not applicable to whatever else they do next.

So you wind up with using "awesome tool if you just understood it" where your hires don't. And the "awesome tool" probably isn't quite what those people find most productive. So it becomes a constant frustration.

Move back to a text based language, and this problem goes away. People use the tools that they know. I'm probably going to write code in 4 different languages this week, and have to look at what is going on on a half-dozen machines..and won't need to switch tools.

On having a textual representation, yes you can do that. And then you've changed your image based language into just being yet another VM for another language. Whether you write code in Java, JavaScript or Python in the end it runs in a VM, and that doesn't matter.

As for LISPs in general, it depends. What I've seen with Lisp has mostly been image based, but I don't use Lisp very often.

Tesla is going to consume the entire output of the gigafactory and build also more battery factories.

The problem is X is never the same. To me the more X is different from all previous Xs and it still gets done the better the developer.

Also, it's real easy to rush and put in shit code and add bugs and all kinds of other problems.

It's the same reason people brag about other criminal endeavours, they want to brag about how smart they are and that they beat the system.

> I don't think flying

I've picked up a bicycle after not riding for 10 years, and it's true, you never forget how to ride. But this is just not true for flying. You must fly regularly or your license will be suspended.

A large part of instrument flying training is teaching you to ignore what your body is telling you and trust the instruments.

Ask HN: Anyone using Branch to track attribution across paid and organic channels?
I'm setting up source attribution for our products across our iOS, Android and Mac apps and looking for reliable yet reasonably priced solutions. The likes of Appsflyer, Adjust etc are fairly expensive and I've found Branch (branch.io/attribution) as a good alternative, at least on paper.

Curious if anyone has first hand experience and advice.

1) Now the taxi can operate day and night without substantial breaks. That reduces per-passenger-mile amortization costs by at least a factor of 2.

2) Especially since amortization cost is also reduced, you might as well electrify the vehicle (this requires some sort of robot arm for fast charging, but I suppose you could pay someone like $0.50 per cycle to plug and unplug a bunch of vehicles in the interim). That reduces fuel costs by a factor of 2 and maintenance costs even more.

3) No driver means room for more people or ability to shrink the car, reducing all the above costs.

So you've now reduced all the other costs by a factor of 2. That means your overall costs are now reduced by 75% or more. Yeah, that's starting to look pretty attractive.

This was definitely the wisdom I've heard historically. I suspect the number may be slightly higher than it was 40 years ago due to digital communication, but a lot of what I hear is that it's just really hard to deal with all the personal, and interpersonal problems that crop up.

This also makes me think if you're lucky and have a low drama team, you can do more than 10, but at the end of the day you're going to get a superlinear increase in interpersonal drama the more people you manage so this number is likely to remain small.
Because it's a "fuck you" to The Man™. A marginal several thousand or whatever is probably a fraction of the amount that's lost daily across the federal government due to negligence.
These companies can also track you by IP address. I've had conversations with co-workers about them considering a specific large purchases, and then seen ads for what we talked about popping up. I'm assuming that if the CPM is low enough, many ad-retargeters will take the risk of targeting ads based on IP address alone.

> The response was not to make cars safer by say physically limiting them to 10 MPH

Umm, reasonably sure that implementing a legal speed limit was an initial response, in the UK at least. It took a number of years (and likely a lot of propaganda, though I haven't looked that closely into it and history is, of course, written by the victors) to allow motorcars to use roads at anything close to a reasonable speed.
