uMatrix is a much more effective way of using DNS to block ads than HOSTS file editing. You can select only certain items from certain domains. Sure, I block Google cookies on most sites, but those sites are dependent on scripts coming from the same domains. With uMatrix, I can permit just the scripts that the site needs.

And I can quickly and easily test different resource combinations to customize my website experience.
In python it is quite commonly used too.

The problem is that it's actually very unlikely you'll wind up with a valuable product. The odds of getting on a user's home screen get longer every day and if you're not on the home screen you might as well not be on the phone at all.

I would like to see Swift eventually become a general purpose programming language useful outside of Apple's niche but it's got enough baggage from its ties to UIKit & ObjC I'm not sure how likely this is to happen.
This doesn't change the huge red flag that should give prospective customers pause.

The device will still operate only as long as Glowforge's servers stay up. If there are internet outages, or the company goes out of business, the device will no longer function as a laser cutter.

The firmware is a very small piece of the puzzle. The cloud service is being portrayed as doing all of the heavy lifting. That's image processing, CAM, toolpath creation, and motion optimization/lookahead. Once the motion is optimized so that the motion system will move as fast as possible within its acceleration limits, the result is a list of explicit instructions for the motion system and laser. Accelerate at rate A for T seconds. After X steps, pulse the laser at a power level of P.

Thus, the firmware simply processes these instructions, and actuates the motors and lasers. That's not to say the firmware is trivial. But in comparison to the overall codebase, it is a very small chunk of the complete CNC system.

I'm not arguing that Glowforge is under any obligation to open source anything. But this is a fairly small concession that does not address the main concern that most people have voiced, the inability to run the complete system on your local machine.
Yeah perhaps he is just indulging in the benefits of hindsight.
Probably mediate in his tent on the virtues of stoic persistence in the face of overwhelming user stupidity.
This is a great step in the right direction, but I wonder how difficult it may be to actually use considering they've removed so much of normal laser hardware. Anyone know how feasible it will be to control it?

http://techcrunch.com/2015/05/20/glowforge-series-a/

How defensible is Glowforge’s laser cutting tech? Shapiro says the key innovation the team has come up with is moving a large number of functions out of the hardware itself and into the cloud. “We have ripped out huge amounts of hardware from the machine — from a typical laser design, and replaced those with software that we run in cloud servers instead of running locally,” he explains.

One example is the motion controller board used on many traditional laser cutters to translate whatever line the person wants cutting or engraving into a series of electrical pulses that choreograph the motor. Instead of using that type of component, which Shapiro says starts at $400, or even using a cheaper alternative controller like an Arduino, the Glowforge uses cloud software to do the grunt work. “We simply send down the ones and zeros for the motor to the machine over the internet which reduces the cost by a factor of 100,” he notes.

“The thing that’s relatively easy to clone is the hardware, although we have some interesting innovations and patents there, but the place where we think we can really add a great deal of value is in the software,” he adds.

> Apple doesn't serve the same encrypted binary to everyone. Each user has an independent set of FairPlay keys and Apple serves up content encrypted for that particular user. That's kind of the whole point of FairPlay. If Apple served the same encrypted blob to everyone, then the encryption would be completely useless as everyone could decrypt it.

I used to think this as well. However, (my memory is fuzzy on this so take it with a grain of salt) a year ago I downloaded the same app from two different iTunes accounts. Both encrypted apps were identical, and had the same encrypted blob. So it seems Apple is not distributing a unique encrypted blob to each user, at least as far as apps are concerned.

Then you're gonna love the product which is a wifi enabled battery monitor paired with a smartphone app that tells you the current charge of a battery.

Actually the fridge lightbulb might have been a better place to source power.

But given a product description like eggminder, I would assume the company would fail anyhow. While there may be some people who need eggminder v2.0, there aren't very many of them. Eventually someone will invent the IoT device to end all devices, much like how the iPhone ended up reducing the number of gadgets a person needs.

So maybe they failed due to lack of iteration, but maybe the wacky gadget business just isn't a good one.
For anyone interested in the dynamics of the Air Force that explain the abysmal performance of the F-35, and why the F-16 can beat it in a dogfight despite being commissioned 40 years ago, look up John Boyd or read "Boyd: The Fighter Pilot who Changed the Art of War." The Air Force is structured to enable and shelter operational failures such as the F-35
Lithium ion might not be the battery tech for high energy density uses once we work out some other, non battery technologies.

Aluminum-air batteries [1] are well studied in the past decade and there is lots more research going on there. Currently the state of the art for such a battery is about 4.7 MJ/kg and the theoretical maximum is as high as 28.8 MJ/kg, at which point the mass of the turbopumps and other fuel handling parts might make up the difference.

Of course there are issues, primarily the fact that they're not rechargeable and have to be chemically recycled. It's currently too expensive to do that now, but once we can do it economically, each airport will just have to have a stock of batteries and a robot to swap them on the jet and we'll have electric flight.

Is there any reason this is getting a lot of press now? I've seen it all over twitter. This thing has been out for a WHILE. I used one a Toms store in Portland. It was neat but I'd much prefer something with a higher resolution. VR is all about resolution imo.
"The firmware is a very small piece of the puzzle."

Probably right. What's needed is source code escrow for the cloud service, so if Glowforge tanks, the code goes open source.
Except the risk is relative. What else are you going to do with your money? What government is backing the money?
It great that they're open-sourcing the firmware, but its still not great that the product depends on "a cloud" in order to operate. I hope that is one of the very first things that gets addressed by contributors .. as someone who has orbited around some nice laser firmware projects in the past, I'll be interested in their source release and see if I can help in some way .. so, kudo's for the open source!

That doesn't explain whether or not the N=1 case is covered by an "integer" multiple of time steps. I'm not aware of a definition any definition of the term integer which does not include 1, which is what the EFF is mocking here.

Even the patent holder said N=1 was obviously included... until that presented a problem and they decided it was obviously not what they intended.

Why is it the case that people believe that the public, who did not write this patent, should have to guess regarding what it may or may not cover when they're also at threat of millions of dollars in penalties should they guess wrong? And that's neglecting court costs & attorney's fees, which are almost always a sunk cost--you pay them merely for getting sued and you have essentially no chance of recovering any of that, even if you're right, unless they essentially get laughed out of court because it's your burden to prove that the case was exceptionally bad... even though you did nothing wrong.

They open source the firmware because the firmware is a dumb client; all the logic that controls the laser (aka makes it not set your house on fire) is hidden in the cloud.
I'm not sure about the other capabilities of the F-35, but judging a modern war plane based on its ability to dogfight is like judging a modern ship based on its ability to ram other ships.

Dogfighting just isn't going to happen anymore in a battlefield where smart munitions are relatively cheap, plentiful, smart, and getting smarter every year.

We are talking about skies that will soon be filled with extremely agile drones and missiles. In that environment, a manned fighter, that cannot pull high-G maneuvers (because the human pilot will pass out) cannot beat a supersonic missile or drone.

We should not build planes to perform well in dogfights in the style of the Korean and Vietnam war. Stealth or unmanned is the way to go.

Having said that, the Chinese long-term strategy of developing high performance drones to saturate the battlespace is probably the smartest idea of all. I don't think any stealth technology remains very "stealthy" for very long, in this era of software processing.

There's a very strict limitation on solar planes that depends on the panel efficiency and other material science avances as well as the shape and, especially, its height.

The bigger you make the jet, the more of its surface you have to cover with solar panels. However, while the mass grows geometrically with the size because of volume, the surface area of the panels only grows exponentially (x^3 vs x^2). Just like with single celled organisms: at some point the surface area can no longer absorb enough energy to support the massive machinery.

There are tricks to increase surface area but the panels still have to face the sun so you're forced to make planes short vertically but very long horizontaly. I don't think existing airports would be able to support such a different design.

> there is no harm with later adding a glossary item

When are you adding this? If you do that when obtaining the patent, all is well and good.

If you do that in court, after saying otherwise, as has been done here, there's quite a lot of harm. People have a right to know what is and is not patent infringement, as they're on the hook for big money.

If you can just change what your patent does and does not cover, on a whim, when fishing for money in court, there's quite a lot of harm in that. Millions of dollars worth of harm. Nobody had any way of knowing what idiosyncratic definitions of words you were using and yet everybody else was responsible for not infringing upon your patent.
This is very sad they failed.
pypy has not been updated in a while (it's compatibility is with Python 3.25).

Well, an obvious step after putting all your eggs in one basket is to silence criticism of that basket. This is just one more reason why the Air Force's decision to reduce diversity in weapons systems is a bad idea. Not only do they become too big to fail, they become too big to criticize.

In a few months you'll be able to easily try the consumer Rift, the HTC Vive and see for yourself how convincing the VR is. I think you might be pleasantly surprised.

While the road toward "perfect" VR is just getting started, these first-gen consumer sets have crossed the starting line, and are qualitatively different from earlier VR experiences.

(BTW, while comfort isn't a totally solved problem, for 1:1 motion, these sets (and PSVR) are pretty good and I think for most people, won't make them sick.)

These folks didn't invent the CNC ecosystem. They didn't even invent the realatively inexpensive laser cutter. If the firmware is GPL, I'm fairly certain plenty of existing toolkits will get drivers for the it in short order.
Ask HN: Can you give me some advice on writing essays?
I am trying to learn to write some interesting essays/blog post, and I need some advice, because I'm completely stuck.

I have had trouble coming up with things to talk about my whole life. I read a lot, and I feel like I know a lot of things, but when I sit down to write my mind goes completely blank, I have nothing to say, or rather I feel like there's nothing worth writing about.

I don't have anything to say to people who know less than me, because explaining obvious things seems boring, and I don't know what to say to people on HN/LessWrong, because I feel like they are smarter than me and already know everything I am about to say.

For example when I read Eliezer Yudkowsky's essays, I think that I already know a lot of the things he is talking about, so before I've read them I had this information in my head, information that could be turned into some interesting writing. I was supposed to be able to write at least something similar, but clearly I didn't. I assume I have some interesting information in my mind, it can't be completely empty, but when I try to come up with topics for essays I hit this weird roadblock, and end up with nothing.

Recently I'm making some progress at writing fiction, but with essays I'm completely stuck, I've got nothing. It's like I'm missing some key element necessary to just start writing things.

Can you help me out? Do you have any advice that could help me to get started?
>The only time you're protected is if the key in question is password protected AND you only memorized the key (ie didn't write it down anywhere). Then you can plead the fifth.

I don't think that's the case. There was a court ruling a year or two back where the court ordered the defendant to unlock his data. The key part of the ruling was that passwords and keys aren't evidence in and of themselves - the court can demand them in the same way it can demand, for example, physical keys for a safe.

Glowforge has enough horsepower to work offline if someone built the custom firmware, albeit without the features that differentiate it from a traditional CNC laser cutter/engraver. We started out the design with a minimal microcontroller but decided to bump up the capabilities of the onboard processor along the way.

An advertising industry where content is still 'free' (paid for by advertising) but the actual curation and safety costs are foisted onto the advertiser rather than the consumer - through a third party - is a nice middleground to strive towards.

That shouldn't make it Affero GPL incompatible as long as they make the code available. Regardless, if they own the copyright, they don't need to follow Affero GPL despite licensing it that way; it only applies to those who don't have copyright.

Though I agree with you that all government agencies are political machines which have evolved to protect their bureaucrats; the F-35 was simply not designed to be a lightweight low-cost fighter. Comparing the F-35 to the F-16 is about as useful as comparing the F-105 to the F-86 (, which is to say not very informative).

Boyd thought that even the F-16 was overweight and over-sized (and he may have been correct).

The comment on the blog seems about right so ill copy:

"Lets see David Axe the nonstop liar that wrote this used the words “commands”, “requires”. and “demands” when referring to the document in question. No where in the document cited are any of those things. This author constantly takes any accusation about F35 and exaggerates it to the ridicules level. He uses thinly sourced quotes and seems to have a vivid imagination. WiB should be embarrassed to have such a talent-less hack writing this drivel… do you guys even have an editor?"

This is a new version and the first non-"Innovator Edition" (read: enthusiasts/devs) - the big deal I think is that presumably as a true consumer product, it'll be getting a lot more distribution, and moving forward will probably a big part of Samsung's pitch for differentiation of their flagship mobile products.

More resolution would be nice, but it's not everything. The biggest issue for VR geeks is probably the lack of positional tracking. A close second (or first, depending on how sensitive you are) is the relatively low refresh rate (60Hz) causes noticeable strobing for a lot of people. At that refresh rate you don't get the temporal super-resolution bonuses you get at higher rates. Fill factor is as important (if not moreso) for screen-door effect - the CV1 and Vive screens are lower-res, but look much better. AFAIK, the S6/N5 screens don't support global refresh (although there is direct front-buffer access). Lack of physical IPD adjustment is a big deal, and it's hard to solve w/ a single screen w/o sacrifices. Oh, and of course, running the devices comfortably w/o overheating.
If they put their content up without charging me for it, then why wouldn't I deserve to see it? If the deal is "look at this ad in exchange for viewing the article", then they could key on the ad as a password for the article.

But that's obviously not the deal, because your traffic would plummet as many of your visitors would reject that deal. So don't pretend an agreement exists here. Visiting a website is not an obligation to view the content or the ads.

The agreement is between the website and the advertiser. They have obligations to each other, we don't have obligations to them.

The arguments you are using are similar to those used to defend the century series; back then they argued that missiles had eliminated the need for agile fighters, but the Vietnam War's rules of engagement meant that agility was crucial. If one is to defend the F-35, it should be on the basis of its advanced strike capabilities, or other design considerations which were given priority.

Perhaps stealth, unmanned, and/or saturation are the best strategies; I am not sure whether anyone can predict what the outcome of an encounter between such asymmetrical adversaries will be in 15-25 years.
