To redistribute code written with Mono for Unreal Engine, you must have a commercial license to the Mono runtime. These licenses are available from Xamarin for Mac, Android and iOS online, and you can request Windows licenses through support.

If you want to code in C# it is the primary language for Unity, and a commercial third party unsupported add on for UE4.
In this case the issue is not that it is HARD but that they don't have people with the right experience in their team. Also in pure software projects, you can cover for your mistakes with personal sacrifices and working crazy hours but with hardware, some mistakes really cost money.
Unreal Engine was free for students since at least October last year (2014).
If you inflate a balloon, the surface area of the balloon increases and some dots drawn on the surface would get further apart but you couldnt say that the enlargement has a 'centre' The entire surface is simply expanding everywhere at once. The universe is like that with an extra dimension.

The fact that nobody has sued them over the (many, many) failed projects suggests that people in general understand the risk involved with Kickstarter much better than you seem to. It is all about backing speculative projects which may fail. I don't understand how you can know anything about Kickstarter and not be aware of that.

Never understood the concept of measuring map size in km. It's like measuring distance on a map while ignoring scaling. Something like source's hammer units make a lot more sense to me.
If you're looking to support AI safety, the Machine Intelligence Research Institute is researching it.
I'm surprised they didn't mention how amazingly insecure it is to be running a phone that old. If you're running a private messenger like Signal, you might not want to install it on a device vulnerable to bootrom exploits that negate all the advantages of disk encryption.
We use POST when we need to because it's an understood solution. I really wish we had a better option. There are so many tools we can't use without modifications. Some examples:

Varnish. POST responses do not have cache control of etag or last modified. Nothings stopping you from adding them, but without guarantees no general purpose tool is going to look at them. For our larger datasets, serving from a fast cache is going to make a world of difference.

Shadow. https://github.com/twilio/shadow Twilio built this out for their billing system as they migrated to a new platform. It only works with idempotent requests (basically everything but POST). It executes the request on both the new system and the old system and compares the output.

The proposed solution here is one I've pondered quite a bit. Making all large queries into two requests would help a lot. The first request is a PUT and returns a URI to a new resource. The second request is a GET.

For large queries with significant payloads, two queries that result in a 304 is well worth the cost. The point of a 304 is to reduce data transfer (as well as cost of generating a response). The new resource URI does not need to be stored indefinitely. It's a time sensitive URI.

All that said, I haven't gone that route yet. It's too new, too "unique snowflake". The old _method=get approach with a POST is going to be understood by all (even if it makes many people cringe).
> Criminal laws have intent requirements

Most criminal laws have mental state requirements, and intent is the highest requirement that criminal laws might have. Many criminal laws do not have intent requirements -- requiring only recklessness or negligence, for instance -- and some are strict liability (requiring only that the prohibited act be done, independent of mental state.)

> and honest mistakes usually don't clear the bar for criminal culpability.

Honest, but unreasonable, mistakes can clear the bar for crimes with recklessness or negligence requirements rather than intent requirements, and honest and reasonable mistakes do so for ones that are of the strict liability type.
Flip the oscillators, the sea is the tree branch, and the swing is the moon.

The tree branch is moved slightly each swing, and if I am to extract energy from the branch by forcing it to do work, I will damp the motion of the swing and it will eventually stop.

You're right in that it's not renewable, the energy is being extracted from the kinetic energy of the moon, and it will slow the moon to some minute degree.
If it's smart enough to be a threat, I wouldn't be surprised if it's smart enough to avoid getting EMPed.

Is there some good historic overview of this issue for e-mail?
There's a lot to criticize here, but one suggestion I've not seen anyone make is some kind of commitment to backers to make them whole.

This is an ongoing enterprise, so there are any number of ways that might happen. One is just to say, "Look, we don't have the money to pay you back now but we are converting your contributions to loans at interest rate $X and will pay you back when we have the cash, which we expect to be $DATE." Or give people a discount on some future product. Free software updates for life. Something. Otherwise this reads as kind of narcissistic: "It's been so painful for us to spend all your money!"

They also made any number of mistakes that are so large and well-known as to be nearly inexcusable. They were clearly learning on other people's dime, and that's kind of a problem when the product never materializes.

Outsourcing design and development is a terrible mistake for a boutique product. While this was a product management failure, the lack of in-house resources was an even bigger error.

For a $500K budget, zero money should be have been spent on design. Let the engineers decide how it looks. You can make it pretty on the second iteration. The first one will be charmingly ugly, and it will exist. Design people can suck down an astonishing amount of cash arguing about fonts, and that kind of thing makes a difference if you're selling to the mass-market, but for a niche/enthusiast/industrial product? No one cares.

I once worked on an industrial product where a design company burned a huge amount of money on everything from UI layouts (mostly unusable) to icon design, to fonts. I re-did their UI so it could actually be implemented with the development and hardware resources available, added a few icons they had missed, and replaced their pricey commercial font with a free one. Number of complaints about the UI from the people who had approved the design dollars in the first place? Zero. No one could tell the difference (I'm sure a designer would have gone spare looking at what I produced, but our customers weren't designers... they almost never are.)

Good design in a mass-market product can be a huge big deal, but hitting that perfect sweet spot the way Apple does so often is incredibly difficult and expensive. The odds of hitting it are so low for a project with limited resources that you're far better off not trying until you've got a shipping product.
It's not really a replacement, more of a secure alternative. Ideally it would be possible to totally replace iMessage with Signal allowing non-secure messages from legacy contacts. However, even if the team were so inclined Apple does not provide adequate messaging APIs. For example, there is no way to intercept an SMS message, see message history, etc.
These essays are embarrassing in how poorly researched they are and dangerous given the gravity of their arguments.
Well, super-massive stars can have extremely short lifespans (of only a few million years). Also the heavier elements (gold for instance) only get created (and distributed) during giant supernovae events which are the end result of these giant stars lives.
But those are regulating current products or services. This is calling for regulation now of RESEARCH in a specific field.
At the same time, though, being paid back shouldn't be a low priority.
I'm honestly not sure if Yahoo is "fixable." I don't use any of their products and I can't see any reason to change that. Everybody else does everything they can do better or is utterly irrelevant to me. But even nobodies can get people on board with a compelling product--I still remember abandoning Infoseek for the then-unknown Google--so it's up to them to create a reason to use it.
Or maybe A1689- evolved into it's magnifier Abell.

As others have indicated, AI planning is a significant field, critical to self-driving cars, space probes, etc. Markov Decision Processes is a great sub-field.

> A good "cuccoo field" for that would be video games, where such planning systems would be a holy grail.

The game developer conventional wisdom for some time has been that very good AI is not worth building [1] because it is not very entertaining. I believe that's by far the dominant opinion. But, there are some interesting ways that AI is being explored in ways other than strong AI opponents [2].

A GLIMPSE of the Galaxy
Well, to be honest, Kickstarter is not a shop. Even though nowadays it's mostly a marketing tool, it's original idea was to be a way to invest in ideas you like. That is, take a risk with your money.
sama, please do everyone a favor and stop trying to emulate pg. You need to pick up a new hobby, or failing that, stick to writing what you actually know about, whatever that is.
I guess that's the end of the argument on if Pluto is a planet :(

"A new, zoomable panorama from NASA's Spitzer Space Telescope shows us our galaxy's plane all the way around us in infrared light. The 360-degree mosaic comes primarily from the GLIMPSE360 project, which stands for Galactic Legacy Infrared Mid-Plane Survey Extraordinaire. It consists of more than 2 million snapshots taken in infrared light over 10 years, beginning in 2003 when Spitzer launched."
In Canada an offer to trade is legally binding. At least for the first sale of a erronous advertisement.

Legally speaking if a company posts a screaming good deal in a flyer or advertisement they have to honour the first sale, but after that may make corrections.

This has been tested in court.

Also, if you make an offer and accept a response by mail, the second the response hits the mailbox (NOT the postmark) it's considered accepted.

So if you offer to sell something, to person A who who responds via mail but sell to person B before the letter gets to you you're legally bound to make person A whole.

This too has been tested in court.

This is why you now see legalize at the bottom of flyers now which says the in store price is the valid price if disagreements pop up.
The whole point of Kickstarter is supposedly to let people fund projects that require a minimum investment to be feasible, without their money going to waste if that minimum isn't met.

If they knew their business model was only viable with 50,000 orders at $99 each, they should have set their target at $5million. Anything else is dishonest and deceptive.
> So when there's little traffic on a single lane side street, let alone the avenues, it's taxis and Escalades busting 40+ always.

While the taxis are a separate kettle of fish, the existence of off-hours speeding by local traffic f'n tells me that your own f'n neighbors do not agree with you. I suggest you f'n take it up with them.

In spite of what you think, speed cameras will only be a temporary solution if people do not think the speed limit is fair. This happened in California with red light cameras. Once enough people knew someone who got busted and thought it was unfair, there was enough political will to scrap them altogether even though there really were intersections that desperately needed them.

This also happened in Pittsburgh with parking boots. Once the city got the biggest scofflaws, they didn't have the usage they expected. So, they started using them for even first time offenders. Well, people didn't find that very fair, so cottage businesses to acetylene torch the boot off sprung up and cost the city a lot since they now had to buy a new boot every time one got torched. Very quickly, the city figured out that over-use of that enforcement tool cost more than it helped.

Enforcement does not create compliance. Enforcement is simply an adjunct to something that most people are complying with already.

If you want people to slow down, you have to engineer the road so that they want to slow down. Speed humps, roundabouts, curb extensions, etc. are all tools to make that work.
Google published a paper which I think is relevant to the topic, Machine Learning: The High Interest Credit Card of Technical Debt (2014).

http://research.google.com/pubs/pub43146.html

The conclusion seems to be that even this level of machine learning decreases controllability substantially. "We note that it is remarkably easy to incur massive ongoing maintenance costs at the system level when applying machine learning."
Ah, turns out you're right:

Finally, research on the possibility of superintelligent machines or rapid, sustained self-improvement (“intelligence explosion”) has been highlighted by past and current projects on the future of AI as potentially valuable to the project of maintaining reliable control in the long term. The the AAAI 2008–09 Presidential Panel on Long-Term AI Futures’ “Subgroup on Pace, Concerns, and Control” stated that:

"There was overall skepticism about the prospect of an intelligence explosion... Nevertheless, there was a shared sense that additional research would be valuable on methods for understanding and verifying the range of behaviors of complex computational systems to minimize unexpected outcomes. Some panelists recommended that more research needs to be done to better define “intelligence explosion,” and also to better formulate different classes of such accelerating intelligences. Technical work would likely lead to enhanced understanding of the likelihood of such phenomena, and the nature, risks, and overall outcomes associated with different conceived variants."

Stanford’s One-Hundred Year Study of Artificial Intelligence includes “Loss of Control of AI systems” as an area of study, specifically highlighting concerns over the possibility that:

"we could one day lose control of AI systems via the rise of superintelligences that do not act in accordance with human wishes – and that such powerful systems would threaten humanity. Are such dystopic outcomes possible? If so, how might these situations arise? ...What kind of investments in research should be made to better understand and to address the possibility of the rise of a dangerous superintelligence or the occurrence of an 'intelligence explosion'?"

Research in this area could include any of the long-term research priorities listed above, as well as theoretical and forecasting work on intelligence explosion and superintelligence, and could extend or critique existing approaches begun by groups such as the Machine Intelligence Research Institute.

Professionally I practice law so yes, myself and my colleagues are concerned about government entities violating not just privacy but the attorney client-privilege...though I digress and this is not what I am talking about, but it does happen.

>but if you look at the "average" person, they have next to zero concern for their privacy.

The "average" person isn't using Yahoo, that's why it would be a niche. I'll leave you with a interesting quote: "A search engine whose users consisted of the top 10,000 hackers and no one else would be in a very powerful position despite its small size, just as Google was when it was that search engine."[1]

Correct. As I mention above this is unfortunately not possible on iOS due to API lockdown.

> This galaxy is so distant that it would have been invisible without the gravitational lensing effects of a large galaxy cluster called Abell 1689, located nearly 2.2 billion light years away in the constellation Virgo.

Straight from the article. :)
If UC Berkeley acted as the author thinks they ought, I would have graduated in 1989 with outstanding skills focused on Fortran, VMS, sccs, troff, and XView. My design skills would probably have included an awesome ability to draw block diagrams of code. Best of all, I'd be very knowledgable about the pros and cons of various tty brands.

Fortunately they taught me stuff which has stood the test of time instead. If you can grok P vs. NP, the Dragon Book, Computing Theory, Data Structures, and a half-dozen programming languages, you can certainly manage to grapple with such mighty topics as "code reviews" and "unit testing".
> Humanity has shown very little capacity to agree on a global scale. The proliferation of nuclear arms and the persistence of human trafficking are two cases in point.

This is very true. Therefore you think regulations on nuclear arms and human trafficking are worthless?
For the sake of its customers, Kickstarter needs to be doing a better job of evaluating projects, as it sounds like this project wasn't viable from the outset. This hurts their credibility and makes me wary of funding in the future.

In the "Refunds" breakdown on the Kickstarter page, it shows that they're refunding the remaining 20%, while Kickstarter is keeping the 5% fee. Shouldn't Kickstarter be refunding their cut?

"We cannot determine whether the email exists or not because the email service has a catch-all address." So, if you don't want to be found if someone uses that tool, then make sure you set up a catch-all address ;)
So, what you are telling me is that we need to put fences on all sidewalks except at the crossings to prevent pedestrians from doing something stupid that could get them killed? That would save hundreds of lives a year, right? Much easier than getting millions of drivers to comply with speed limits they don't agree with, right?

Everything has a cost, and it's very easy to blow that off if you don't have to pay it.

And, before you suggest that no one would ever put up a fence like that, California actually does occasionally. Generally where pedestrians try to cross a 12-freakin'-lane-superhighway on foot.
Yes, I see now that I was only half paying attention to the article and skipped a bunch of words ;)
From personal experience whilst traveling through Tanzania & Kenya using a 4G modem from Safaricom the issue was/is latency. Bandwidth is plentiful but the latency is horrible which resulted in AJAX applications timing out before requests could be completed. Example of this was Gmail, the application would not even function in AJAX mode but switching to plain HTML mode, whilst it took forever, worked like a charm every time.

The quaternions are a subalgebra of geometric algebra. It's not quite the same in that it's strictly more general and, therefore, more broadly applicable.

It's great to see that competition's result both supported and extended!
In materials engineering there is a similar technique to the articles "misfit analysis" used for materials selection. It is not uncommon to have competing constraints. For example to address a problem like designing a beam section optimally you want a beam thats as light as possible, meets the minimum stiffness requirements (usually with an added safety factor) and is still competitvely costed - depending on how the constraints are weighted (cost vs weight vs performance) it could mean the difference between aluminum, steel or carbon fibre for example. The real science lies in expressing the constraints and weighting them against one another correctly.
Why you can no longer trust any USB device plugged into your PC
Awesome! I have always wanted to work on Unreal Engine 4, but have almost always been a bit skeptical on the pricing.
This is awesome.

Back in the day, writing cross-platform code meant knowing the ins-and-outs of each platform you wanted to support and coding specifically for each one. Interpreted languages (like Python) and runtimes (like JRE) take a lot of the pain away, but that means all those programs have a dependency: the interpreter or runtime.

Go isn't interpreted and bundles its runtime inside the executable. That has always been pretty great, but with Go 1.5, the programmer won't even have to run `env GOOS=... GOARCH=... make.bash --no-clean` before compiling for another platform.

With veteran OS and systems engineers working on the language, this is why we can have nice things.
Are you suggesting that's what we should do in the face of this potential threat?
In Source the scale is fixed (1 "unit" ~= 1 inch) and I imagine the same's true for UE.

It may be true that no one has sued Kickstarter, but people -- including the State of Washington -- have sued failed Kickstarter projects.

If no one has sued Kickstarter, that may mean that Kickstarters has been successful at direct responsibility to projects rather than Kickstarter itself.
Indeed. Two of my friends managed to build a custom robotics platform that bridges Lego Mindstorms and traditional electronics for way, way less money. They managed to do that because both are EEs who were fully competent to design and manufacture the prototypes of the product. They're on Kickstarter now (https://www.kickstarter.com/projects/1992634922/robocore-the...), with a finished product (seen it myself, it works as advertised) and they're aiming for 1/10th of the amount.

The lesson should indeed be, don't go to Kickstarter unless you are dead sure you have all the expertise you need to finish the project in-house.
When you can run assembly on it, unless of course you are emulating a computer without assembly...
Partial measures do matter; in fact, currently most of the advances are coming from the US. And research can be regulated. Probably noone will catch an independent researcher working alone and not releasing anything, but progress tends to come from teams of experts who have come through elite labs/universities. Furthermore having significant data&hardware seems to be helpful for making progress.

It doesn't require mass surveillance for something like this to work. I'm not saying there are clear positive next steps, just that blanket dismissals on the basis that perfect enforcement won't be reached are silly.

We shouldn't actually trust that positive effects of every technology outweigh negative ones; that seems obviously wrong (think about weapons tech for example).
