3D printing and electronics manufacturing strike me as two totally different animals for most applications. There's a lot of variation in cases and the like, so this is great if you need it right now, nobody has to keep a warehouse of that stuff and if you're doing something new (i.e. iterative design and development), the immediacy can't be beaten.
This has a lot in common with POD books.

For a computer like this, you simply don't gain a lot. It's mostly prefab components, with a bit of PCB and soldering. No big need for made-to-order, built from scratch items. You'd get almost nothing out of this, apart from a "support your local automated shop" deal. The eco impact of transport for electronics is negligible.

Now, I'm not saying that there isn't a spot for "local electronics", but that would involve other devices, ones that are highly experimental, customizable and/or short run. If you'd get things like this (or an embedded systems) with oodles of different connectors, memory options, different processor subtypes, or open source hardware (probably FPGA based, to make it more reproducible). I've been dreaming about stuff like that since I read about "nano-facs" in the Cyberpunk RPG…

But again, I don't see the big deal for the Raspberry. It makes sense to print a sole copy of "Best fly fishing sites for Llarregub Creek in late autumn" in your Kinko's, not to get a copy of the Bible or Harry Potter.

15-year-old facing jail time for downloading 24 movies
I had done all of this by the time I hit 10th grade. I hated my 10th grade geometry class because I preferred spending my time writing 3D games to applying the law of cosines and proving millenias-old theorems. I'm now confident that was the right choice.

They have design patents, which are even more insidious. These were added in 2003 and didn't get much interest accept from the big fashion houses trying to stop counterfeits from entering their territory.

As you can see the law has been widely spun out of it's original scope to include all types of things design related.

Show HN: Ravid Video Messenger (because MMS is terrible)
Likewise. We're an all-Mac shop, we do semiregular audits of everyone's machines, and I've never seen this happen.
This is indeed ridiculous.

I've always been pretty neutral towards Apple but I this is just appalling. Seemingly they cannot compete with Android in the normal way so they try the patent troll angle. I hope this backfires on them big time.

I don't want to live in Apple's locked-down walled garden.
This is Sandeep (co-founder of Ravid). My co-founder (keithba) and I found that sending private, asynchronous video messages on mobile devices is way more difficult than it should be. We created Ravid to solve this problem.

Note: US-only for now & requires a phone (so no tablets.)

The stack & tools:

* Rails 3 (MRI) for our API servers.
* Worker nodes running Sinatra (JRuby) w/ Resque
* Monit for monitoring services / Fabric for quick provisioning
* The Android client is typical Java (using IntelliJ)
* iPhone development w/ Monotouch!
* S3 for storage, and our public website using Jekyll
* C2DM message delivery (our Gem: https://github.com/sghael/speedy_c2dm)

Lessons learned so far:

- Fragmentation on Android is a b. Especially when dealing with hardware stuff like cameras, expect to do a lot of device specific coding. Front-facing cameras are a perfect example. Gingerbread solves these problems in theory, but not in practice.

- Uploading video files over mobile connection is non-trivial (duh) - We've put a lot of work towards reliable and efficient uploads and downloads (intelligent packetization, retry logic, etc). We solve for the "elevator scenario". User sends a message, but steps into an elevator half way through delivery. Aside from Gmail, most mobile apps suck at this.

- On the positive side, 4G+ speeds are really impressive.

- Creating a portrait oriented camera application for Android is way harder than it should be (really poor API implementation around camera rotations). Contrast to iOS where it's super easy.

- UX matters - A friction-free UX required a lot of work. We had many alpha testers (both family and friends & paid services like usertesting.com/mobile) that helped us find the sticking points.

We'd love your feedback on anything!

The Latest Terrorism Non-Menace: Pilot Potty-Break Attacks
If this actually works as advertised, I hope it makes it to market as fast as possible. I'm pretty much done with the days of having new cavities, but I have composite fillings for all the cavities I did have, and ten years down the line they're starting to go bad. It's incredibly frustrating to have a dentist tell you you need to have an already-filled tooth re-drilled because the composite isn't sealing the cavity anymore and decay has set in around the edges where no amount of brushing could have prevented it. With any luck the current generation will be the last to suffer this fate.
This book: Mathematics for 3D Game Programming and Computer Graphics, Third Edition (http://www.amazon.com/Mathematics-Programming-Computer-Graph...)

StackMob, The “Heroku For Mobile”, Partners With… Heroku
I don't think it's possible to come up with the 80 to 90 percent that he claimed. The top marginal rate for federal tax is 35%. State taxes and sales taxes can be deducted from income for federal tax. Social Security tops out at $106,800.00, and Medicare taxes are 1.45% on all income. As far as the estate tax, he won't pay that - unless he inherited the money. His heirs will pay an estate tax on anything over 5 million dollars that they inherit from him

The federal estate tax tops out at 35%, but also excludes some property and deductions. New York state's estate tax is also capped at 35%.

Finally, the estate tax is seldom actual double taxation since a large percentage of estates subject to taxation are in the form of stocks or property which are not taxed until they are actually sold.
No, it detects the release of CO_2 from the blood to the pulmonary alveoli.

Presence of CO_2 in the alveoli signs the presence of a blood flow, regardless of the nature of the pump (heart vs CPR).

If the blood flows, the organs (including the brain, which is the most sensitive to oxygen deprivation) are properly fed and viable (assuming CPR started soon enough).
Part of my point is that even engagement might not be the best metric. For example, here in hn, I'm far happier if people don't post than if they post something trivial or uninteresting (your post and comments are interesting as I think this is a discussion worth having).

"There is a concentration of tech startups in SV because the internet lets them sell to the rest of the country without issue."

I don't think so. If the Internet was all that was needed to explain this concentration, then that would not be a sufficient explanation because it would prompt a new question. If geographical proximity was due to the Internet, then why Silicon Valley vs some other location?

I think that it is more likely that there are a high concentration of tech startups in SV because the concentration of tech companies in SV offers positive externalities to firms that locate themselves in SV. This is not a very good article (even by wikipedia standards), but I think that it could help to paint a picture:

http://en.wikipedia.org/wiki/Economies_of_agglomeration

But then, you are right. If tech companies needed to be within a hundred miles of their customers in order to transact business with them, then they would not be able to benefit from agglomeration effects. But I think that there are probably other things that factor into as well - margins, competition, regulations, etc.

"Brick layers / construction are far less mobile because you need to be at the construction site to build a brick wall."

I agree, this is true. Perhaps I should have been more selective with my examples. One more thing that is also true is that a side effect of their lack of mobility is that it is more challenging for them to scale vis-a-vis the technology companies.

"PS: Read the millionaire next door and you find a lot of people in the use that made a few million from those bricklaying startups. The main difference is it often took them 20 years to get where software companies got in 5."

The OP cited bricklayers as an example of million-dollar startup companies not being unique to the computer industry. I think that your point about how challenging it is to scale more conventional "mobility-challenged" businesses is actually a very convincing argument against the idea that starting a computer company and starting a bricklayer company offer comparable potential rewards.

Holding all other factors constant, if bricklayer startups are more geographically limited than tech startups, then it is reasonable to hypothesize that tech startups have a higher probability of becoming million-dollar companies.

Also, with regards to the Millionaire Next Door, I think that it is worth repeating the old axiom: the plural of anecdote is not data.

I think this will be a minority report but:

Although I hate Apple's heavy-handed approach to this, I also like the message that this sends to Asian companies, who have quite a cavalier approach when it comes to "borrowing & adapting" the designs and innovations from others. The list is long and is by no means limited to Apple: Routers from Cisco, phone designs from Motorola, etc. etc.

It may be impossible to properly enforce copyright and trademarks in China and other neighbors but at least this shows that Europe may be a different battle ground.

'Embarrassing revelation' indeed. How in the world is it possible that a German court can impose a EU-wide ban in a trial that contained what is basically fabricated evidence? How did this slip past Samsung's lawyers ( I remember this whole thing blowing up at the hands of the tech media, no? ) Didn't the court do its own, independent, impartial research into the matter? Why didn't the court compare some physical devices as opposed to basing a decision with such far-reaching consequences on some printed pictures?! Can somebody who has studied the law explain to me the benefit of allowing plaintiffs to have command over which court they want to litigate in? It feels self-defeating.

After reading this I'm also surprised how the author of this article can possibly assess that, "there’s also Dusseldorf, Germany, where judges are proving themselves quick [and] competent" after this incident that demonstrate just how patently (!) incompetent they really are. But I guess this is just testimony to the fact that actual evidence and reason are tertiary in a justice system that can be defeated by cherry-picking courts that are friendly to whatever the litigator's cause. How can the public trust in a judiciary framework that functions with this total lack of precision and attention to detail.

On a different note, and I'm sure nobody really cares but since Düsseldorf is my hometown I'd like to point out that it is spelled with an umlaut. If for some reason you can't do that, how about spelling it Duesseldorf :) That's how it's done in German if you can't use the umlaut for any reason (url's etc.). Is it common to just leave out diacritics when dealing with foreign vocabulary in the english language ?
Hardly surprising[1]. And I don't think this will make a big splash against them. The public doesn't care and Apple fanboys will be Apple fanboys. I expect some apologetics any moment on Daring Fireball any moment now…

NB: I'm typing this on a Mac. I really like the OS and the desktop/laptop systems, but since they've become the big mobile player, there's not a lot of progress in those fields and they're getting increasingly litigious. Time to install Arch on some spare machine again…

Just remember Apple is being sued as much as it's suing. Yes, it is disgusting business practice across the industry, but nobody is immune and nobody is pure. Apple gets the most air time because they are Apple.

Take some of your anger and let your representatives know how sick the patent system is. Then do it again and again. We need to get the message to them!

EDIT: Yes, this case is Europe, but if America became more intelligent with patents, Europe, who already is more intelligent, would likely follow.
And initially I thought that EPO patents didn't applied to my country (Switzerland), being outside of the EU: well, I'm wrong...

the most common phenomena that leads to that kind of heart activity without any actual pumping result is a ventricular fibrillation, which looks like this: http://www.ecglibrary.com/ecgs/VFNORWCH.gif, compared to a regular rhythm looking like http://www.grundkurs-ekg.de/definition/ekg1_neu.jpg. This is ( likely ) the underlying problem. What's described here is the fact that the medical personel was able to determine whether their actions ( CPR ) where effective enough to maintain blood circulation. there are, of course other metrics, like o2-saturation levels etc, but this one seems to be especially suitable.

One note aside, it's not uncommon for a resuscitation to go on for 1 or even 2 hours, it depends on the circumstances, the patient, the medical situation and most importantly, the timespan that elapsed before cpr was first administered, which was obviously quite fast in this example.

By comparison, law and medicine have long since circled the wagons. It used to be that to be a lawyer, you only needed to pass the bar in your state of practice. Sure, many aspiring lawyers did attend law school, but the profession was not hermetically sealed. Today, you have to pass the bar and have graduated from an accredited law school, at tremendous cost. Same story w/ medicine.

So these $400K salaries do not translate to $400K in value produced. Maybe $100K, maybe $200K, but the remainder is rent-seeking. Meanwhile, your modest salary of $75-150K if anything undervalues your product. And this is good! You have a produced a surplus. You are the engine of progress. Yes the rentiers will take their cut, but the rest returns to society and benefits society.

There is an important thing missing: In order to prove that someone is dead, you must do electroencephalography. This will detect the brain electric charges. Normally, since the patient isn't dead, there will be brain pulses, which will prove he is alive.
Is an exploit "malware"? No.

Could an exploit be used to install malware? Yes.

So, no, it doesn't count.

iOS definitely isn't without security issues, but it doesn't have the same malware issues that plague Android.
Ask HN: What happens to failed entrepreneurs?
In his essays, Paul Graham often mentions that even entrepreneurs who fail at their startups are usually much better off (in terms of experience, and perhaps monetarily too) than they would have been had they chosen not to start (see for example: http://www.paulgraham.com/notnot.html). As an aspiring entrepreneur, I find this rather encouraging. However, I am looking for data or detailed stories on failed entrepreneurs with more than just a few data-points. Successful founders get a lot more media attention than failed ones, so information on the latter seems to be generally lacking on the Internet. What do founders do after failure? How do they know they have failed? Where do they go next? If they do another startup, is it harder to get funded by VCs? If they look for a regular job, is their experience running a startup valued? Are there other hidden challenges a failed founder must face? Not to be a pessimist, but I feel information about failed founders is a bit of a blind spot for me (and maybe others too), and it would be very useful to get more factual data about this subject, from members of the HN community.

Signals intelligence and counter-intelligence is a narrow view of how computers can impact the battlefield. While the NSA and CIA may have some capability beyond listening in on enemy communications, I question whether the responsibility to make attacks on foreign targets which could be considered acts of war should be left separate from the military.

Weaponizing computers can have a much broader use that would be appropriate for a Cyber Force in addition to military intelligence operations. For example, today we might want to knock out a communications array, a factory, or a power plant in enemy territory. Our options at the moment are to send in missiles, bomber jets, or an elite ground unit. But those aren't always good options. The missiles and bombs could cause unwanted collateral damage to civilians. Missiles and bombers are crazy expensive and so is the cost to get them to the target. The risks to using an elite ground unit are enormous not only to the unit itself but to foreign policy if they are killed or captured.

But a Cyber Force could electronically disrupt or disable a facility through any number of means. This would be far cheaper in terms of financial and human costs. Even if there are counter measures in place for the facility to run offline on a private grid, such an attack could sufficiently hinder it until it can be disabled more permanently.

This is no different than sending a bomber jet instead of an infantry platoon. The goal is to make a surgical strike, the generals need to choose the right tool for the job. For an increasingly large class of technologically advanced targets in increasingly urban areas the military will more often want to employ hackers instead of bombers.

The point, then, was that this will be equally true for enemies wishing to attack the United States. A dedicated team of hackers can easily cause as much or more damage than a fleet of bombers. And the United States can either be ready for it or watch as enemies walk over them with impunity like the United States air force flies over enemies today.
So it went from 25 to 44 over the last quarter? .00017% malware. Still, no-good if one app gains popularity before it gets noticed. And this will only get worse.

I'd like to see a secure app store from Goog. It'd be easy to grow as they could start with the most popular apps from the current marketplace. Eventually phase out the open marketplace and let users sideload apps if they want to risk it (plus, they could still make "but we're _open!_" claims).
To be a little more speculative . . . if it is on GPU, is there some way of using rendering operations?

I don't understand. http://www.wolframalpha.com/input/?i=life+expectancy+at+21 says that my life expectancy is 76.62 years and my probability of dying is 0.001329. That's a really low probability of dying already and I haven't even weighted in statistics like being healthy, high income, and taking the bus instead of car or bike. I can't believe that my probability of dying before I'm thirty is any higher than 0.1%.

Syntax highlighting doesn't seem to do anything. Isn't it a little grand to be calling this an IDE?
If you do the naive implementation:
int temp = x;
x = y;
y = temp;

Then a sufficiently smart compiler can decide to assign, say, %eax to x and %ebx to y, and then just rename its notion of registers, and after the swap just begin using %ebx for x and %eax for y. A swap with no copies at all!

(It won't do this in every case, and it depends on context, but such an optimization is possible... but not with xor swaps.)
