I think the biggest thing Boston Dynamics are dealing with ( aside from power density ) are improving balance and running algorithms, under the stresses of heavy loads, non-homogenous terrain, and loss of friction.

It's possible to use deep learning for controlling the servo motor positions and torques, the hierarchy of features is then varying levels of abstraction over the set of positions. The most granular layer may be features related to all the torques and positions of the servo, a higher layer may be some combinations of subsets of these, and the highest level may be features akin to the general representation of the spatial position and tension of the limb.

It's quite naturally similar to how human kinetic intelligence and perception works, say you are learning how to dance, you can be aware of the position of all of your limbs simultaneously ( the general pose you are adopting ), or you can be aware of the angle and position of your ankle or your right hip independently ( what your foot is doing ).

I think there could be things to learn from the networks in octopus limbs -- because of their extensive innervation.
Lounge memberships are 100% worth it. With an Alaska board room membership you can access the Cathay Pacific lounge at SFO as well as any American Admirals Club (which aren't generally anything special).
I think you may have misunderstood something here. The high school static fiction model is:

frictional force = normal force X coefficient of friction

i.e. frictional force is independent of surface area according to this model.

The next big mistake is configuring your packet filters and application ACLs to only filter requests coming in from the internet; they can still make requests to 54.175.131.207 or whatever the IP is and the source of the request packets will be from the loopback interface.

And the IPv6 equivalent is "::1". Did they even set up basic packet filtering or ACLs for IPv6 requests? If they have no public IPv6 address, they probably never did.
It's not gamefaqs, the business model was to be the Lynda of gaming (says it right in the article!). That is: Pro players teaching beginners who want to learn higher level play, through video and other rich media. There is demand for this in esports style games (LOL DOTA CSGO), but higher level players just start their own channel to do this through youtube/patreon.
Okay, so forget the word felony. "You would have aided/abetted a malicious criminal and profited monetarily by doing so?" My point is that selling an exploit doesn't become morally okay just because the company doesn't offer a bounty.

A few years ago (2012) I was taken aback by the Unreal Engine development process. Their IDE features a running game with all elements being selectable and interactively editable. In one video fragment [1] they hop to Visual Studio where they change gravity. After a few seconds of compilation, the game's code is updated.

Just an idea, but would it be possible to add support for the GIFV format [1] so that the source images or videos aren't converted into GIFs?

Maybe it's just me, but it seems crazy to create a much larger and lower quality animated GIF from an MP4 only for it to be converted back into an .mp4 or .webm video after you upload it to Imgur for example.

Isn't part of writing a business plan doing the scenarios of what happens should company X or any other competition enter the space and pitching what would be your competitive advantage. Who plans a non-technical business on the basis of 'no one else will have this idea'. It sounds to me like the OP had a poor business plan to begin with. The fact that there were people willing to fund this just shows that in this bubble will throw money at anything.
> What's it based on, if not an actual curve of growing revenue?

It seems common knowledge enough that budget and revenue forecasts for seed stage start ups aren't going to be precise or very accurate. For investors, that part of a pitch would be meaningless.

"We forecast 1.2 in revenue by our 2nd year."

"How much revenue do you have today?"

If they had prior success, they could raise a round on that, otherwise it would be the standard pitch: size of opportunity, here is what we have so far, here is our team and how great they are.
Which countries prohibit free websites? Do they block Facebook and GMail?
I'd really like to see a solution to how we validate ourselves to banks and other financial institutions as it becomes apparent that Social Security numbers are no longer an effective barrier to identifying a person. It would be nice if we could easily change our identifier and have a service which banks used to validate against.

Something similar to using Google to logon to certain services rather then creating a user name and password. Then you can make a single point much more secure and difficult to log into.

The downside of this is that I think the US government would have have an in person verification system to get an account. I.E. you go into the DMV, get an account and then you are connected to the service. You can then implement 2 factor authentication, and you link that service to your bank accounts.

I have no clue if this would actually be more secure then what is already in place, but it seems more then likely that hackers already have my Social Security number and my previous residences because of the OPM hack.
Design Hunt: Creative Jobs
I've done this sort of thing a few times for different clients who need to be able to put something out on the web quickly and easily. It's a useful technique. And if done right, in my experience, a lot easier to "lock down", and leaner than if you were depending on a full-fledged CMS system for the same sort of thing.

The one thing you have to warn people about, however, is that Dropbox (last I checked) does not scan files for viruses. There are of course ways to incorporate virus scan into the pipeline if it's not already being done by the user.
> Then just paying that developer will cost $1000 per box on a 100-box production run; paying a team of three such developers for two years would still cost nearly $700 per box on a 1000-box production run.

That's not correct. Development is a fixed cost -- you don't rewrite all the software and re-design the hardware every time you run a new production run.

Furthermore, this isn't even necessary for hardware stuff where production run size actually does affect cost. If the machines are developed in house and you know you'll be using them for the next 15 years across the whole US, you can do a few medium-sized production runs.

Which is exactly why federal and state governments should have a permanent bank of software engineers and EEs for routine software projects like this. Then they can do what makes sense for the taxpayers, instead of having to play fiddle to the profit motives of an incompetent money grubbing contracting firm.
“opt-out” is certainly correct (though, as I understand it, Pocket, as with all parts of Firefox, is only loaded when it is actually used, so “opt-out” does not seem to tell the whole story to me). I do disagree with the “non-removable” bit. Fully disabling it, to me, counts as removable (though I can understand why someone would disagree).

Perhaps I just read something into the Author's tone (probably due to all the vitriole from the typical discourse around the integration) that wasn't really there. If that's the case, and all the author meant by that statement was that the code itself could not be completely erased from Firefox as-packaged, then that seems to be factually true, and I simply read it incorrectly.

The short version: Super Meat Boy for PC connected directly to a MySQL database to upload levels created in the level editor. The DB address, username, and password were all stored in plaintext in the binary.

Yes, doubling the screen on one side raises the pixel count by 4x... but right now 3D graphics cards have at least a couple of orders of magnitude more graphics power than they need to drive a conventional 2D display, and 3 or 4 isn't out of the question, frankly. It really isn't a problem in 2D. Compared to any modern 3D game it's still a walk in the park for them. They've been overprovisioned for 2D work for a long time now. Even non-3D cards were getting pretty powerful before it just wasn't worth shipping 2D-only cards anymore, really, and that was a long time ago, and graphics cards have gotten scarily more powerful since then.
What are the units of that coefficient? Per square? And are we talking force or pressure. Hm.

The experiment used blocks with hook-and-eye screws. You dragged them across the surface linked in a chain, then again stacked, in twos and threes. The result came out nothing like a linear relationship.
Liverpool, UK -> Toronto, Canada

Applied under the Federal Skilled Workers program once I passed the threshold of required points. I always wanted to live in Canada because of the better standard of living and wages.

It also cleared up my wife's visa status - we were at the mercy of the UK Home Office whether my wife could stay in the country. If I lost my job when we applied to renew her visa she would have had to leave. Canada cleared up all that uncertainty as we are now permanent residents here.

Canada has one of the most generous immigration programs in the world. Check it out.
Well, of course the middle ages would never invent sex toys - that chastity belts exist now can only mean they are recent, because people had not kinky fantasies back then.
Luddites may be the best example ever that history is written by the winners.

Suffice to say, early industrialization was abysmal for the workers, who really had no choice but to take whatever bad deals they were given. Corporal punishments were used to inflict respect and security didn't exist.

So Luddites were bascially revolts, and in several ways a precursor to the worker's movement that came later. It nearly escalated into civil war (at one point more soldiers were occupied with fighting Luddites than Napoleon). Leaders were tortured and killed.

In propaganda, they were bascically pictured as lazy and/or against technology itself, which carried over to the modern meaning of the word. Well worth a read.
As stated in the wikipedia article, the microwaves penetrate to a depth of about 1cm (give or take, depending on the food). So, in a sense, it can be argued that the microwaves heat from inside, though in reality, not very far inside.

The trouble is that microwaves work mostly by heating liquid water. Ice is not liquid water and absorbs microwaves relatively poorly. The already melted parts tend to heat up faster while the still frozen parts heat up very little. This, in addition to the limited penetration, is how you wind up with food that is napalm hot on the outside and still frozen in the middle. If you are trying to defrost something or cook it from frozen, you are much better off using a lower power setting. The peak power output is actually the same, but it gets turned on and off (you can hear it cycling) so that the warm areas of the food have more time to transfer some of that heat to the still cold areas through good old fashioned conduction. Incidentally, this is the same reason that the instructions for many pre-made items tell you to let them sit for 1 or 2 minutes before taking it out of the microwave.
Yes, I did too. And I'm saying: it isn't universally, or even usually, the case that Google giving something away destroys any market for selling something similar.

Your starting point is wrong there: the DOJ wasn't against them for making it free, but for bundling it with their OS.

They could offer it for free all they want. Similar in the EU, they weren't against them for it being free, and once they stopped bundling it and windows media player, they were off the hook (even though they still offered them for free).

I think you're overestimating how much fuel could be saved by this. You need 7.8 km/s of delta-v expenditure in any event because that's orbital velocity. Generally a rocket uses up 10.5 km/s of delta v to reach orbit with the difference being atmospheric and gravity drag[1]. So you'e got almost 3 km/s of delta v you could theoretically save here. You'd probably lose most of the atmospheric component but there's still the thrust you need to counteract gravity for however long it takes you to reach orbital velocity. The lack of air means you can safely accelerate a little faster but you're still limited by the weight of your engines and the heavier structure that faster acceleration requires. I'd put the reduction in needed delta-v at closer to 5% with a fuel reduction around 12%.

Follow the money.

People who buy ATMs have a strong vested interest in their security, both physical and virtual. If the machines can be broken into or hacked, the people who buy the machines lose real actual cash. If the machines merely malfunction, it upsets their customers, which then costs the machine owners.

Ultimately, you can run the numbers on security to see how much money it's worth, how much it costs, and find the ideal tradeoff.

Voting machines have completely different incentives. The buyers have no vested interest in their security whatsoever. I would actually argue that they have a bit of a vested interest in insecurity, because a successful voting machine hack would probably cost people their jobs if it came to light, and if a machine is so insecure that you can't even detect hacks then this risk goes away. And if the machines malfunction, users often can't even tell. Even if they can tell, their unhappiness typically won't financially impact the people who buy the machines.

And thus we can see why, for example, Diebold builds good ATMs but craptastic voting machines.

Yeah, you're misunderstanding what they do. It's like elance, but without the race to the bottom on pricing. You can do everything from very small jobs up to hiring them directly into your company.

Gun helps you find somebody that fits your requirements, which I think is a step up from elance and the like. They even kick freelancers out of the system if they scam customers or produce poor quality work.

I'm not surprised you're disappointed with the quality of work from elance and similar. Anyone and their dog can offer services through that platform, and the reality is that the people doing the hiring often don't know what they actually want and they don't know how to evaluate the quality of what they're given (on a technical level), so it's pretty easy for a bad developer to get a 5 star rating.

Perhaps, but my intuition is that the bottleneck between most people and programming isn't the tools. It's that programming requires the programmer to conceptualize the problem formally, and then to formally define what he/she wants the computer to do.

We can come up with better and better formal languages and ways for editing these languages (and probably should), but I would guess even a visual formal language, will still pose many of the same difficulties for users that existing formal languages do.

There was also the address of the other internal services.

I think the best way here is to put the "fetch random URLs" service out in its own subnet, where it cannot access any other internal services like the EC2 status service. You'll also have to validate the URLs (no non-HTTP-or-HTTPS URLs) and prevent things like the redirect attack from working.
