Ask HN: What do you think about a 3D printer for your child(ren)?
I'm working on a project that may result in a software package that allows children to digitally create toys, then create them in real life on their own (very simple) 3D printer to play with - and I'd love to get your feedback.

If you could include if you're a parent, as well as the age(s) of your child(ren), that'd be very helpful.

Thanks!

I'm just going to throw this out there: the UFCW has had Kroger, Safeway, Supervalu, and the other major players paying for fully subsidized insurance. Every employee working more than 80 hours a MONTH has had medical insurance for their families for more than 20 years.

And Safeway's president reworked the plan 10 years ago to require preventative care like annual physicals, arguing that the ounce of prevention was cheaper than the pound of cure.

The amazing thing (as far as I have been following it) is that Uberspace encourages its users to learn to use the command line and SSH instead of restricting them to a "safer" GUI with fewer options.

It will be interesting to see if educating a growing user base does scale (as more knowledgeable admins may ask fewer questions and can find their own answers on StackOverflow) or introduces more (and much more complicated) customer support requests over time.
This is terrible. I am from India and I know how deeply copying is rooted in the brains of students here. Basically, all parents (and thus children) care about is marks. So, students learn copying and tend to copy all the assignments. Plug, we have professors who are good for nothing and accept this equally.

Recently, I made a small web app and got lowest marks in class for project. In another project, when I told my idea to professor, she was all like, "this is too small, increase the scope!" So, my idea of attendance tracker expended to "Learning Management System". I used WordPress as foundation for app and added plugins. Instead of testing anything, professor asked, "What does "collapse menu" do?" Nothing else asked.

Other people who copied it all and shied crappy command line "hospital management system" and other things scored way higher than me.

While all people do not copy here, copying is not checked at all and this indirectly encourages it. India is worst place to be a programmer right now. At least in college. I don't think companies are any better. I had a friend certified as "Java Programmer" for a crappy one day program.
Use the right tool for the better job
For those running testing (or sid/experimental) I highly recommend apt-listbugs -- it will list (critical) bugs related to packages you're about to upgrade/install -- and allow you to back out. Often you can just hold off a few days, and some hardworking Debian volunteer will have made the problem go away -- before you need to experience it.
And more importantly why does it have to be at the Federal level, clearly MA thought it was a good idea and passed it -- it's not working well, but hey that's there choice. Why must everything be a national policy?
Yes, I read what you wrote and disagree with it. I have seen no evidence that the USA can execute on massive projects when it has shown no ability to do it in pilot programs. If the VA and IHS don't represent the pilots for this bill then what does? That is one reason there is a fair history in the USA of pilot programs. In the US, small projects are fair predictor of larger success because of a pilot first culture.

No, the cut in Medicare is justified by the saving from fraud detection. Perhaps you are thinking Medicaid?
Asus also sells Linux systems via Amazon in Germany, that is how I got my netbook with an AMD Brazos CPU.

The only issue is that they only do it occasionally with a limited set of units.

I posted this article because it touches on a subject that my friends and I were talking about on a hike last week: how does society handle a world where production is so very efficient that relatively few people need to work to meet the basic necessities of the world's population.

Some of my hiking friends didn't like my solution: a broad socialist style safety net to cover only basic needs with (probably) stiff competition for the fewer jobs, assuming that most people would want as good of a lifestyle as possible for their families. A good job == money for travel and richer experiences.

I see such a future world as an exciting place!
Any hint?
Have you atudied economics? The OP reads like someone who has and is utterly incredulous at the statements being made by Bitcoin's proponents. In fairness, the gentleman interviewed in this article insisted it was all an experiment. But the WSJ editorial board has a long time habit of being very non-mainstream and almost Austrian with its economic views, so this interview was likely intended to play into a political narrative.

Here is a summary of what he is trying to say:

1. Bringing up hyperinflation in Zimbabwe is a common tactic of right-wing/Austrian economists to warn of the evils of government control over fiscal spending and currency, and that our current course of monetary expansion means that we in the US too are on the same path.

This ignores of course that (a) Zimbabwe had a civil war at the time and the government confiscated or destoyed most private productive capacity; (b) we are in a liquidity trap currently, which in short means that money is nearly free to borrow at 0% interest. Companies are sitting on piles of cash or continuing to unwind their debt from the 2008 crisis, therefore we have not enough people spending. Printing money has had no discernible impact on inflation over the past 5 years. In fact, we could use a bit right now - to encourage spending!

2. The thought that "encouraging saving is good" therefore fixed currency and deflation is good.

An economy is a closed system - if some are saving, others have to spend to keep the music going. If we all stop spending, we get into a depression, where people lose their jobs, and the economy isn't working to its potential - all because the currency is rising in value.

In short, it is arguable the point of an economic system is to make and consume goods and services, not sit and watch your bank balance grow due to the psychological whims of the market.

3. A currency based in faith is not a dangerous thing - basing currency on gold is mostly a form of superstition. and it has real drawbacks (see #2).

Lots of things in the world are based on faith in institutions or theorems. Bitcoin is too - faith in the algorithm, that it works and won't be compromised. Also (blind) faith that a fixed amount of Bitcoin will not lead to destabilization.

Now. Does that help? These arguments lead to exasperation because they seem to happen over and over across decades in slightly different forms.
"I seriously do not understand why everybody has rolled over so hard on this issue."

It is the same reason that Linus Torvalds and plenty of other people have no problem with TiVO, or even see it as a success. A lot of people in the open source community do not subscribe to the free software philosophy. For a lot of people, as long as they can boot Linux by some means and continue to hack, there is no problem, even if Microsoft's signing key is required in that process.

Plenty of people also live in a state of denial about the bootloader restrictions. They do not believe that Microsoft would ever deny anyone the ability to turn the restrictions off, or that Microsoft would otherwise prevent us from running GNU/Linux. How anyone can trust Microsoft to not abuse its power is a mystery to me, but there are lots of people here on HN who seem to have such trust.

At this point, I do not think there is any debate about the FSF's stance on the open source movement:

The author is being deceitful with his chart and it throws this entire article in question. Just because you draw a line and call it stagnation doesn't mean it is. The chart is a monthly change in employment not cumulative growth.

I like the technical idea of these items, but in reality they don't really provide any added usability. In fact, I would say they take away from a message more than a standard icon. The idea of an icon is to instantly convey a message. Adding an animation to said message on hover doesn't really add any extra 'reason'

That chart is admittedly pretty terrifying. But the article itself argues the big reason is because Canada's nationalized healthcare plan has more leverage and price control capabilities than US Medicare. That seems more reasonable than simply attributing it to corruption.
More and more advice on being a better programmer comes down to being a better, more focused person.
> Is it really the case that there's an argument that this can't work in the US because there are more people?

The simplest such argument would be that there are diseconomies of scale - it's conceivable that the bigger you make a bureaucracy the less responsive/effective/efficient it gets. That certainly could be true - whether it actually is is an empirical question.

Another possibility is that our federal system is ill-suited to the task. There's nothing really preventing individual US states from providing such services. And if most states haven't done so thus far - and in the few that have tried, it hasn't worked out very well - there might be reasons for that which we should try to understand.
Which is why here in Canada the health care is provided by a province-level organization, which is partially funded by the federal government.

I agree there's a range, but if you have to abandon an analogy to describe another end of the range, then it's time to find a new analogy. I think one trap in the article's logic is thinking that all structural engineering is at the scale of bay-spanning bridges or skyscrapers. Structural engineering can range from structures that withstand earthquakes down to a shack to stash your garden tools--just because one end of the continuum requires more rigor than the other doesn't make them unrelated.

In software engineering there are still rigorous requirements in fields that run software on other planets or in medical systems, but there's software with looser requirements as well.

The best metaphor I've encountered for the wide variety of software engineering was a talk that covered the book "How Buildings Learn" http://www.amazon.com/How-Buildings-Learn/dp/0140139966 -- there are structures that favor adaptability, and others that favor rigor, but that doesn't mean that structural engineering doesn't happen on one end of the continuum compared to the other.

(To be fair, there are rigorous forms of writing, too, but I think restricting the analogy to only novels is too narrow to be effective.)
You underestimate the supposed role of randomness in evolution and science in general. The universe itself is supposedly the product of a random explosion. Hence, my phrasing, "that all of this occured randomly".

From there, life sprang up and evolved into these insanely intricate and complex life forms and systems. Give me a break. If people choose to reject religious explanations, then OK. But, it's a bit rich to pretend that science has much better answers to the really hard questions at this point.
On your point 2. Saving doesn't have to mean saving money. It can mean investing in stocks, bond, or funding start ups.
The conclusion drawn at the end, via chart, is completely wrong.

It's wrong for the same reason the old Bush vs Obama job chart from the election period was wrong (both sides context dropping).

There is a reasonable limit to the number of jobs an economy will or can lose, unless you're talking Zimbabwe style economic armageddon (that takes decades typically top to bottom). Even then, in the most extreme of scenarios, it runs out.

After the point of maximum damage, job losses will revert to close to nil by default. The side the author is claiming as recovery, is not recovery but rather it's continued job losses in fact (at a gradually lessening rate). So it's remarkable to see it used as an indication of recovery, when it doesn't inherently indicate any sort of thing. A chart with an arrow pointing up does not mean recovery.

If you took a look at the Spanish economy right now, which suffers from intense 27% unemployment, you could run a similar chart on their unemployment. For it's a mathematical requirement that eventually the job losses must slow to a trickle, and at that point some idiot economist could claim that as a proof of recovery via a similar chart with a fun arrow pointing up to lessened job losses. Noone would confuse 27% unemployment, in which there are low job losses, as a proof of recovery - context matters.

In the same vein, producing 100k jobs per month on average is no proof of stagnation just because the average is flat. That is to say, there's literally zero strong evidence to suggest it would have been better without Obamacare. The US economy has problems far worse than the mess that is the implementation of Obamacare. We began losing massive numbers of manufacturing jobs at far back as the 1970s, all the way through the 1990s and 2000's. The inflation disaster the Fed gave us over those 40 years, is continuing today, and is approximately a million times larger a financial issue than Obamacare. If you wanted to look for the reason for the destruction of below middle class paying jobs in America (most service jobs), that'd be the first place to start (the impossibility of keeping up with just 3% to 5% perpetual inflation).

A real discussion on all of this would require detailed information on the types of jobs being created, the number of hours those workers were getting, the portion of those that are 2nd or 3rd jobs, and so on. It would also require examining the number of people falling out of the work force versus jobs created, and on and on and on. That would be context.
Citations needed. The primary argument used against ACA's constitutionality was struck down by the supreme court [1]. And there already exists at least 50 government agencies that reserve the right to pass regulations without congressional approval [2].

Don't think of yourself as a kid. As long as you have the algebra background, you can learn CS from the same resources as anyone else. How you go about studying CS really depends on your situation and learning style. Does your secondary school/sixth form (I'm guessing you're British from your writing style, else high school) offer computer science courses? If so, I'd highly recommend you take them from your school. Even if they don't have great teachers, they'll give you a structured form to learn CS principles. If your school doesn't offer CS courses or you want to supplement your learning, I'd highly recommend you take Coursiva/EdX courses for the topics you would like to learn. This, of course, takes patience and discipline, but you'll end up being very prepared to study computer science at university.

A global installation of IPython now recognises if you start it with a virtualenv active, and adds the virtualenv to sys.path so that you can import modules installed there.

It isn't limited to packages in the virtualenv - that is, it always behaves like you created the virtualenv with system-site-packages enabled, because it is importing its own modules from there. But for most interactive use, that's not a problem.
Maybe that guy had a big exam or a build going on that day. I am just saying :).
The real issue is that uninsured people are an externality to society.

If we actually let people choose to not buy insurance and deal with those consequences, that would be fine. But as a civilized society, we don't find it acceptable to let people die for preventable reasons, so society ends up footing the bill for that person.

Either we need to let those who can afford it and choose not to purchase insurance die of pneumonia if they can't afford the treatment, or everyone needs to buy health insurance if they expect to be treated for life-threatening conditions.

It's not a matter of "spend your money how you see fit". It's "you choose not to buy health insurance and we pay for it anyway", which is patently unfair on the rest of us.
I severely doubt the average American has any sort of experience with the Canadian health care system whatsoever, let alone "first-hand" or "up-close".

The average American probably didn't even know Canada had universal health care before 2009. Shoot, the average American might still not know that.
What I don’t get is why anyone would oppose a bill that makes affordable healthcare accessible to more people.

Ignoring the philosophical debate for the time being (something as a non-American, he at least tries to understand), his premise seems to be that Obamacare makes affordable healthcare accessible to more people. That (along with the philosophical debate) is the argument.
"An economy is a closed system" that's not quite true.

The economy is a balance between things that create value and those that destroy it. In a healthy economy more value is created than destroyed so as long as the 'savings' is close to the amount of new wealth created there is no problem. The problem is when people try to store more value than than the genuine amount of new wealth created. Often it's as simple as a bubble created by over-investment followed by a crash back to actual value. However, the special case of people 'investing' in cash cash does strange things which are directly harmful even without a crash.

How do they avoid theft? My town tried bike sharing and within weeks all the bikes were gone or destroyed.
> The so-called social healthcare as pushed by the government will inherently waste a lot of money because government is always wasteful with it's resources. Governments are wasteful because whenever they run out of money they have the option to tax people more. On the other hand companies that waste a lot of money will eventually be removed from the marketplace, as they are unhealthy.

Which large companies that sell health insurance have gone bankrupt due to being wasteful with money?

The incentive to "not waste money" in the health insurance industry is "deny coverage when possible". Is that really the best way to provide healthcare for all Americans? Presumably that's the real goal that we all share, and we're just arguing about the best way to do it.

If government-provided health insurance is too wasteful, why does the American federal government spend more money on healthcare than most other countries (not even counting the American private healthcare expenses), with worse outcomes?
Well yours may be the typical scenario. I had the slightly opposite experience.

I built Warehouse management system with RFID. i bought a RFID reader and few cards, connected with serial port to PC and basically had a checkout check-in system in place (for the curious, Java is the language, sadly i lost the original source code :( still have the RFID reader tough ).

On the demo day the professor was so happy with my project, the first question e asked was "From where did u buy this project?" . He was very reluctant to believe that projects of such scope can be built by students. If the professors are so sure the projects are copied, why do they even grade them?.

Ya and most of the students in my class bought projects(C Compiler, Steganography etc,) for few thousand rupees and got equally good marks (Hey , i got the top mark ;) .
I'd be worried about:

1) Safety: Choking hazard, heated plastic, etc.

2) The ability for children to be able to use 3D modeling software. (this problem would be solved with the proper software)

"The American rights impose no obligations on other people"

I still see Ceph as competition to supercomputer filesystems and not really as competition to GlusterFS. For example, the design of it directly attacks the problem of centralized metadata (especially useful after the DARPA project to bring it to Lustre failed).

I was working on an unrelated project with one of the designers of Ceph (UCSC's Scott Brandt) and in conversation he also seems to concur that Ceph was really built as a replacement for PanFS or Lustre (but still may be useful for other things of course).

Using it to replace GlusterFS still seems odd to me. It feels like they're both solutions to different problems.
The instability we have seen is with the metadata server, but have been able to relatively quickly push fixes to upstream as we encounter them. The focus has been on stability, and we have been running pretty large terasort jobs without issue. In the upcoming release of Cuttlefish, due out any time now, there will be locality information exposed to Hadoop for better task scheduling. We will start focusing on improving Hadoop performance soon, now that things have stabilized.
> German style model of healthcare.

Which has the curious drawback that those most able to contribute to it (i.e. those earning more than X €/month) are allowed to opt-out of it. I never quite understood why this would have to be the case, and the various attempts to introduce an actual public health insurance system failed so far.
Remember the perfect is the enemy of the good.
