There are a couple issues with the article that I'd love to address.

While DD was making progress with its 3D-printed gun experiment, the company managed to get a license to become a legal manufacturer and vendor of guns, somewhat muddling the legal status of the 3D-printed gun, a weapon anyone with a 3D-printer could make at home.

There's absolutely no "muddling" here. You can do any amount of gunsmithing you want, at home, and it's legal without a manufacturer's license up to a very specific point. You can feel free to make a stock, a trigger, a pistol grip, etc., but just don't make a receiver. On some guns there's a lower and upper receiver, in which case you can make the lower without the license. Make the upper without a license and you're in trouble.

Side note: don't make a silencer either. They are easy enough to make and you don't need the license to make it, but you do need the license to own it.

The Liberator still has some more testing to go through

It's probably damn close to a 1-shot gun and then replace the barrel. It also won't have rifling so it won't be accurate. The cartridge next to the gun in the picture appears to be a .22 short which is probably the maximum the plastic can handle. I wouldn't want to be anywhere near this thing when a .38 or 9mm cartridge is fired. The plastic won't contain the significant force.

but the lack of requiring a license — and the gun’s lack of a serial number — are unsettling thoughts.

Much like you don't technically need a license to make a gun, you don't need a license to drive a car. Simple guns have been made by machinists for a long, long time. And you don't need a serial number on a gun either but if you are found with a gun sans serial number it's a felony with huge prison time. But cops see guns with serial numbers shaved off all the time.

I understand the threat of plastic guns getting on a plane or through security but you'd still need to get a bullet through as well which wouldn't be so easy.

Ask HN: help me find a post ft. a one-page comic strip about drawing
Dear community, my advanced google & hnsearch skills having failed me despite my best efforts to remember the appropriate keywords, I have this unusual request:

Approx. one month ago (order of magnitude) someone posted here a link to a one-page comic strip. It pictured the evolution of an artist on his way to mastery of his drawing skills.
From what I remember, the artist had "a good taste" (watched Calvin & Hobbes – &/or star wars as a child), persevered where most people stopped until finally achieving the quality he always aimed for – but never attained – the previous years. (final picture of the guy behind his computer screen with a graphics tablet).
Does someone remember this post ?

I'd really like to retrieve this submission as I wanted to share it with a friend who just started publishing his drawings on the web.

FYI, if you're into the drawing thing, there are some related posts that I ended discovering today: https://news.ycombinator.com/item?id=3032389

Stunning improvements. By the way, you should definitely check my friend's work there -> http://pierrefeytis.tumblr.com/ – and maybe I'll take the freedom to present his company here, he's a motion designer & associate at http://vodcreation.eu/ they do short movie clips to present your startup/business/service/event if that's what you need (working essentially in France, Paris).
Oh yeah, I also caused a small explosion at school by filling a water bottle with LN2.
> Something that sets these apart from the Raspberry Pi are that they full of easy access I/O

How so?

I thought RasPi has plenty of I/O, but I'm not familiar with BB.

Minor quibble: The lack of analog sound output. It shows that their mindset was not entirely focused on the robotics / DIY genre, but more on the miniature computer thing. You don't do sound output on a robot or controller from HDMI.
All great points. I'm surprised that I never experienced these problems till you pointed it out. Could be because my usage of Gmail is strictly personal. I would have run into these I used it for work (deleting signature, modifying subject etc.).
For what it's worth, the new title is more accurate and more likely to get me to click.

Finding the Right Words to Confront a ‘Showroomer’
The point is M contains the fixes required to make A-B-C plus A-D build. Then you have no histories in that tree that don't compile.

Like you said, A-B-C-D' DOESN'T build, PRECISCELY because D' is the same diff as D. You need to make A-B-C-D'-M to get a working build, but the history A-B-C-D' is STILL BROKEN.
This is seriously oddpants, but I could not log into HN until clicking on this link, at which point I was automatically logged in.
Remember that a hammer and a pair of pliers is also a "gun" if you happen to have a bullet. Its dangerous to fire, hard to aim, and has a very low muzzle velocity, but it does meet the criteria.
You're right about delivery. This is something we are going to work on. Don't think of us as a competitor. We want to create an infrastructure and we need client solutions to work with us ;-)

I was just listening to Adam Savage's "Still Untitled" podcast where he talks about blowing stuff up as the least favorite part of what he does.

That's not to say he won't come to her defense, but I was surprised to hear that.
No problem, thanks for posting the details instead of just "try it now." It's just a matter of time before I would have done something similar. I appreciate the opportunity to learn from someone ELSE's mistakes for a change---one of the benefits of HN.
So Kiera, I think what is being done to you is a gross abuse.

I could not agree more.
If its like the tech industry once he made it clear he was serious (and sometimes even before that) they might reach out to him.
I may be in the minority here, but I actually think most changes to the Gmail interface have been improvements.

My biggest gripe was when they did the overall visual refresh, which reduced the information density on my small laptop screen. Then they added a "Density" switcher, which made things alright again.

I actually like it when interfaces change. Even when I was super busy I wouldn't mind learning and adapting to changes interfaces. Oh well, I guess I just like change for its own sake.

I don't think it's nitpicking. It's the difference between the standard way web forms work and Gmail overriding a known behavior to do something else.

That said, after you hit tab, you'll probably type a word and hit space, which will then click the button and send off the message.
I am inclined to think that the school would have had the same reaction regardless of the student's race. It sounds like a classic case of, "How dare she learn things we did not sanction in our curriculum?! She needs to be punished!"
Great work. I worked with RTMP for some time and I recall the pain to reverse-engineer their protocol. One other comment, maybe the title should be more like: "How I improved a slow/inefficient RTMP video streaming service by 20x". Just a thought.

The only to prevent it, is to implement the two-facotr authentication on protocol-level instead of application-level. This brings you to smartcard-authentication, or VPN solutions (using smartcard or RSA tokens)

But if they would implement that, everybody will start screaming that they have to pay for a smartcard or rsa-token...

Be honest here, how many of you would actually want to pay for that?

yeah, thought so...

Good feedback. To address your comments:

>> This just seems like a wrapper around webrtc, with some presence stuff thrown in.

It turns out there is quite a bit of server-side infrastructure required to support webrtc apps. The biggest ones being relay, STUN, and signaling servers. Operating these yourself is non-trivial, especially if you want good performance around the world. We also have a pretty full-featured chat service.

Doing a good job of session management (which is a large part of what our javascript framework does) is also a pretty complex problem, especially doing a good job of handling a single user logged in from multiple devices / browser tabs.

>> Your website does not mention anywhere that the majority of web users do not support webrtc

Good point. We should definitely cover supported browsers. Since full WebRTC support will be enabled in Firefox 21, the majority of web users actually will have support soon. Also, I have no data to back this up, but I have strong anecdotal evidence that users who have webcams and do video chat are much more likely to be on a modern browser.

- Is this a product?

It's a platform that includes cloud infrastructure (signaling, messaging, STUN, and relay), a javascript framework for using said infrastructure in your own web app, and a pre-built "web client" (a skype-like web app that you can use on its own, in conjunction with your web app, or not at all).

>> Why would I use this?

If you are a developer looking to add WebRTC to your app, the answer is that running the cloud infrastructure to support it is hard and costs a lot of money. We take care of those parts.

> Are you actually aiming at replacing skype?

As a general-purpose communications network, no. As a tool that businesses use to communicate with their customers, yes. A surprising number of companies, including a lot of startups, are doing skype calls with their customers, which involves walking them through the install process, adding them as contacts, and then coordinating the call. Everyone who is doing this hates it and is looking for a solution that doesn't require an install, doesn't require a permanent "contact" relationship, and has better call quality.

>> Do you intend on having users embed it in their site?

Yes, absolutely. One of the most compelling use cases is to have customers placing a call from your site, while your reps/salespeople/stylists/doctors/etc are using the "web client" to answer the calls.

>> Make paid chat applications with your platform?

This is certainly possible and is a use-case we want to support, but the bigger problem we're trying to solve is let business communicate more effectively with their customers on their own web sites.
I was talking about not having to worry about device drivers and things "just working", you're talking about being on the latest and greatest version.

Those are two different discussions.

Obviously when Apple controls the hardware and software there are going to be some trade-offs, one of which, as you pointed out, is a lack of frequent updates.

I, personally, am just fine with that.

Too bad she didn't make a dry-ice bomb. I think a lot of states don't categorize it properly as an explosive device because it is caused by a phase-change and not a chemical reaction.

Oh and response to the officials that said this:

>Their response: kids should learn that "there are consequences to their actions."

That is a disingenuous response that could be used for any punishment. Kids can learn about consequences without needing a draconian punishment. No one every suggested not punishing her.
Commenting on internet forums and engaging in debate is at least better than clicking "like". In terms of conversation, the "like" button is DH3, where comments and debate can potentially be DH4 or higher (http://www.paulgraham.com/disagree.html).

If I "like" a support page about marriage equality, I'm not convincing anyone who holds an opposing view. That's not necessarily true of commenting on e.g. HN.

Of course, commenting does nothing for many issues, such as those requiring money, but a comment can be marginally better than a "like".

I think what is being discussed is a TN Visa for Canadian citizens. Generally, it is very easy for any Canadian to come work in the U.S. as they just need to go to the boarder to have some paperwork signed off for their TN Visa. But, the problem with SpaceX is that we have to follow ITAR Regulations and can only employ permanent residents (U.S. Citizens and Green Card Holders). TN Visa Holders unfortunately do not fall within either of those groups. If anyone is interested in working at SpaceX, then definitely apply or contact me. Cheers!
"Maybe"? Bringing race into a discussion makes everything worse. Don't do it unless you have very good evidence. There's enough injustice here already to talk about.
In the late 90's some guy trademarked "Halloween" in France, because "Halloween" wasn't in any French dictionary back then.
He made an incredible fortune by going after all of those (starting with McDonald's and Disney) making Halloween-based advertising.
jdc... it's the name of the actual article...
> By the traditional definitions, you have the lower class (proletariat), middle class (bourgeoisie), and upper class (aristocracy). People who work for someone else--in exchange for a wage meted out by that someone else--are lower class, no matter how high-up they are in their particular organization.

The "traditional" scheme I'm most familiar with has the proletariat, the petit bourgeosie, and the haute borgeoisie; that is, the post-aristocratic system used in 19th century discussions of capitalist society. The petit bourgeosie includes both what would, in modern terms, be elite and white collar workers (technical experts, managers, etc.) and small business owners (who may technically be 'capitalist', but are nevertheless are dependent largely on their own labor for support even if it is not wage labor), while the haute bourgeousie are the major capitalists.

Both the proletariat (lower class) and much of the petit bourgeosie (middle class) work at wage labor, and the proletariat and the whole of the petit bourgeosie are dependent on their ability to find a market for their labor for their living. The haute bourgeosie corresponds very closely to how you describe the aristocracy, but the distinction between the proletariat and the petit bourgeosie is not at the point where your description draws the line between the proletariat and the bourgeosie; business ownership isn't the sine qua non of the middle class.
Speaking of "nefarious purposes":

Blythe Masters, the creator of the CDS, is about to be put on the financial chopping block for her influential role in "nefarious purposes" (aforementioned creation of "convenience" and usage) that others also have the same usage of such "convenience".

http://dealbook.nytimes.com/2013/05/02/jpmorgan-caught-in-sw...

Where am i going with this?

I'm sure the unemployed youth of spain and greece would long to get their hands on a couple "Liberators" for their "nefarious purposes".
As some of the others said, I see this as complementary, since you can deal with logic on Layer 7 with ease.
So much for a socratic free Internet. Someone should make a hacker news without censorship
That would be a comforting fiction. However it seems that this prosecutor might have a pattern of behavior consistent with taking race into account:

http://raniakhalek.com/2013/05/02/prosecutor-behind-kiera-wi...

While the component you're talking about is real, I'm sure, I suspect that the part of it where a young girl curious about science has her life ruined is probably at least as motivated by race as by control issues in the school.
We ran this experiment a few times and it took most people about a minute to install Skype if they already had an account, and at least a couple if they did not. On many machines (such as mine) it can take 30 seconds just to open Skype.
I'm from the US and have never heard that either.
Based on the name Liberator and the shape, it's probably an homage to the FP-45 Liberator: http://en.wikipedia.org/wiki/FP-45_Liberator

The FP-45 was created to basically be good for one shot. You would use it at close range to incapacitate someone with a better weapon (e.g. an occupying soldier) and take theirs.
This brings to mind an interview I saw on Top Gear once with an Olympic athlete after the Olympic games in China, and he commented on how he ate McDonalds before competing.

His reasoning was that in a foreign country, the last thing you want to do before competing professionally is to subject yourself to food you are unfamiliar with (or just don't know if the local variety will cause problems).

Similarly, in parts of Mexico where US citizens are advised to be careful of the water, if bottled water isn't available or desired, a bottle of coke or beer works as a stand in, because there's trust in the product and it's uniformity across regions.

Note: Yes, I know Mexican coke is different[1], but I'm lucky enough to live in CA where I can get it at any of the 10 Taquerias within a mile of me.

You are definitely in the minority liking change for its own sake.

I enjoy change if it's at worst neutral in impacting functionality but when it makes the application/system/whatever harder to use then it's obviously bad.

New Compose is terrible and they're saying they'll get rid of old compose soon.

The new reply interface is terrible.

The new interface doesn't play well with the GChat boxes either. It used to be that the reply box was small enough that it was trivial to have it on the page at the same time as your GChat, but now the chat boxes will overlay the replay area if you have more than 1. They do this because they want us to be chatting via Google+. But nobody uses Google+. And rather than convincing me to start using Google+ what they're doing is convincing me to ditch GChat and GMail.
I wouldn't call it a total fail. Tab moves focus to the next input element on almost all web forms, in this case the send button. It allows you to send the message without moving your mouse in a fashion consistent with how we use web forms, much like how I can submit this comment with tab+enter.

Their integrity? THQ was about to tank, and they wanted to flip the games to whoever they could.
I'm sure that if there were THQ-internal beta versions for Linux and Mac, they would have happily shipped them.
The analogous technological situation is with color printers and counterfeiting money. The color printer did not bring about a "counterfeiting revolution" or "distributed currency" or anything like that. Simply manufacturers of the printers have software preventing printing of realistic currency.

When the 3d printing industry reaches some sort of maturity, IF it ever goes mainstream, similar measures will be instituted.

Hell, I haven't read the relevant law but quite possibly he's already in violation of the Undetectable Firearms Act. Any federal prosecutors keeping up with this story? Ortiz?

Basically all you have here is a privileged middle class kid who enjoys media attention and getting reactions from people.
I convinced my little brother to do a science experiment where we measured the explosive power of black powder by seeing how high it would launch a metal ball out of a tube ( We basically made a vertically fixed homemade cannon ) He brought our apparatus the balls and black powder to his presentation. Had he done this today I imagine he would have been arrested for possessing a weapon of mass destruction.
Definitely. I would value some feedback from you as well.
When it comes to law and guns, don't be wrong. One oops and you're in prison for 10 years.

On some guns there's a lower and upper receiver, in which case you can make the lower without the license. Make the upper without a license and you're in trouble.

Not in the USA. Here, the "lower receiver" (at least for the AR15, the quintessential semiautomatic rifle most presume for this discussion and what DD is making) is the gun. Uppers you can freely make; lowers you can make in small quantities so long as there is no indication you'll sell them as a business.

[Silencers] are easy enough to make and you don't need the license to make

OH YES YOU DO. It's a $200 manufacturing tax per item, background check, Chief LEO signature, and related paperwork before you start making one. This is one of those things that WILL get you 10 years in prison fast.

HN being an international phenomenon, your jurisdiction may vary greatly in both legality and severity of punishment for violations.
I'm not sure your comment was all that appropriate.

I think untog's comment is spot on. There are lots of stories that seem to get upvoted for reasons other than their own merit.

Pointing that out in this case is probably appropriate.
