I have to be honest, I do feel for anybody losing their job, but it makes me happy to see makerbot doing poorly.

These guys really did a mean thing to the maker community. Not only did they betray the trust of everybody that helped on that project, but it seemed like they wanted to take credit for 3D printing, as if capital M makerbot was THE THING that had suddenly made 3D printing explode.

No. It was the efforts of thousands of hackers all over the world collaborating that made 3D printing explode, and it wasn't fair to those people to see Bre's face all over the news, as if he had personally designed and built all of this stuff.

Time heals all wounds, obviously, and I hope there are good things for everybody involved with (or previously involved with) makerbot. But I hope that this is a lesson: being mean to people isn't cool, and they will turn on you and market against you when you do.
It's not a matter of not wanting people to engage. It's a matter of not wanting to provide a platform for engagement when the web itself is that platform.

I read a lot of blogs which disallow comments. Their engagement comes through linking other blogs and responding, or linking tweets.

I wouldn't call it arrogance to disallow comments. It's a matter of encouraging people to create their own platforms from which to respond.

(That said, I have nothing against comments and think comment-first sites like this one are valuable. But not every site needs to provide a platform for engagement or risk being called arrogant.)

Which government requires insurance on a private home?

Mortgage lenders make homeowner's insurance a condition of the loan to protect their assets. I've never heard of a state requirement for homeowner's insurance.

I'm in the US, though. Might be different elsewhere.

It's sad because human beings are losing their jobs, which always sucks. It also sucks because this is a big market player, and them going under may hamper investor confidence in future 3D-printing ventures or give consumers the impression that consumer 3D printing is dead. Additionally, if they go under it would mean that there are suddenly lots of schools and libraries equipped with makerbot machines who are no longer capable of getting support or replacement parts, which would also serve to dampen public adoption. Finally, it's sad because makerbot had so much potential, and although it's been a long time coming and they completely brought it upon themselves it still sucks to watch it end up like this.
Responses to software seem to follow patterns. Sysvinit is basically Windows XP. People hated it for its lack of sophistication until it got replaced by Vista with its enhanced permissions, which people found inconvenient because they required slightly different interactions, and then XP became, if not good, at least the best in existence. Systemd will eventually be replaced by a minor revision which addresses the main complaints of the vocal minority, and then when NeoUpstart establishes dominance despite a massive list of bugs, systemd will rise to immaculate status and everyone will brag about how they used it before it was cool.
When they opened a brick and morter store in Boston, I remember walking in with a real sense of excitement but walking out without any interest in becoming more involved in the 3D printing scene.

If anything, seeing the printers in action made me realize just how inessential their product seemed from a layperson's point of view.

For all of the potential 3D printing has, at the moment it is a solution looking for a consumer problem, and most consumers aren't looking to make custom figurines or embossed text.

A few months ago, I walked by the storefront and it was totally empty. Apparently I wasn't the only one disillusioned by seeing their product up close.
They get to spend less on training, making employees more commoditized.
One of the sad things here is that tech was one of those interesting, creative things people in SF were doing. It fit right in with the funky, artsy town you're describing. Ironically, tech was actually one of the early casualties of the tech boom. It's still out there, though, here and there.

Short term exposure isn't much of an issue, unless you inhale or ingest it. (Simply playing with it isn't going to send out massive amounts of vapor; it's not super volatile.) The real fear is that it seeps into a hard to clean place and provides a steady stream of vapor over a long time.... basically what the OP illustrated about his house.

Previous generations had no qualms playing with it or lighting it on fire in science class. While it might not have been super healthy, we also don't have a generation of mad hatters.
It's worrisome to me that I'm now getting in my emails offers for extreme discounts on their printers as part of customer loyalty (I've bought PLA filament from them, but not a printer). I mean, that's not generally unexpected, but 40% discounts? That does not instill confidence as a buyer, unless they're now going for the "always on sale" model.
I would imagine it's the verification and figuring out where it is that's a hard problem. How would you reassure yourself you got it all, especially if it seeped through the floor?
Probably, possibly, statistically contributing -- yeah maybe. But other automakers have made decisions that directly, indisputably, really killed people. Usually to save a couple of dollars on a part.
Wow this thread has confirmed what I always suspected: shipping a car is a bad idea. I have actually pulled a car behind a U-haul through multiple states, but that was me, and I know how to pull trailers. A friend of mine in Hawaii was all set to ship his car from the mainland until I pointed out how little sense the math made.
The funny thing is that whenever I have to remember whether stuff in general expands or contracts when heated/cooled I immediately think of water and have my answer. But then I have to remember to reverse my answer because that's the one big exception to the rule.
"An insurance company with no ability to pay claims is not a very useful insurance company."

I have known Jared for about 8 years. He is one of the kindest and most intelligent people I know. Talking about a complicated topic with Jared is a joy. His incisive mind gets to the heart of things extremely rapidly. I often find myself thinking about the points he makes days after the conversation. Any founders would be lucky to talk through their business with Jared.
Doesn't that make sense? Insurance is to cover immediate problems, but the risk given the driver increases with each claim (I'm assuming, that just makes sense to me). So, premiums should reflect this.

While that's true, you still need sun for solar panels. I grew up in the cloud forest without electricity, and solar panels are a drag. Hydro is a much better option there.

Alternative energy isn't a one size fits all sort of deal. And it's not an either-or deal either. The more research is done in any area benefits everyone.
>What is the impact on people when their energy costs are raised? (Hint: energy - vast amounts of it - goes into everything, from growing food to producing artificial heart valves.)

There ought to be minimal impact on overall energy costs since renewable energy is capable of filling in the demand at the same cost these days.

Renewable energy is also perfectly capable of ramping up supply to match demand (unlike oil or gas there isn't a hard resource limit to manufacturing capacity).

I'm no stranger to the GPL. I had a project which spent 9 months arguing with legal in a large institution to support 6 months work involving an independent open source contractor to work on a GPL'd thing.

But it is a restrictive license. Its "plague"-ness comes from its incompatibility with other licenses. Or at least, in the case of ZoL/CDDL and Linux/GPL, the crippling practical realities of the resulting kernel module binaries that are a derived work trying to impose restrictions on each other. That's why you can find precompiled modules on the ZoL website, but never in a distro.

That's a legitimate criticism, but as you say, also its defining feature.

Sorry to hear about the problems at makerbot ... This company really got out in front of 3D printing and made people excited about it. That being said, maybe the growth was a little to aggressive. I remember seeing a makerbot store here in Boston in the last few years-- a lot of people watching the machines in awe, but no one was actually making any purchases (as in the printed items they were trying to sell). It just seemed more like an expensive showroom rather than a store. So cool, though!

I'm still bullish on the maker space. I saw a functioning prototype of this 3in1 machine in Pittsburgh last year.

CNC routing and laser cutting/etching included and priced much better. The maker machines will just get better and less expensive and I can't wait.

The alarming concern is that by creating 70k new jobs in the South Lake Union, that's roughly 70k units of housing near SLU that are going to primarily higher earning white tech workers. This is raising rent in all of the central city (including many historically considered neighborhoods of color) and pushing lower-earners further and further away from their jobs, their churches, and their communities. Yes, eventually the latter two will move with them, but to separate these communities is painful and their labor is still needed in the inner city.

Please do see my other post [3].

I want to make it very clear - I do NOT agree with the rulings and RIAA bullying. If you want to be upset at someone - call your representatives and ask them to start passing laws that are in favor of scraping.

As an aside note - to expand on my original post. Emulators are not illegal by definition (unless they circumvent/bypass encryption - but that's a whole other ball of wax), downloading a free or open source community made ROM for the emulator is not illegal. It is, however, illegal to download a ROM for a copyrighted game. Now, Nintendo isn't going to come after you for playing an old NES game in the privacy of your home - it's still illegal but they aren't going to expend the legal resources and the amount of bad PR to make an example out of you. They may and probably will come after you if you sell or distribute said ROMS.

I've never seen a more FUD headline than that. Got to love the journalistic sensationalism at play here.

To clear this up: the technique in the article is literally what we use in unit tests to check that our TX-based event code won't break under malleability. It's something that Bitcoin developers have been writing code around forever (and warning about just as long.) So truly: if there's anyone out there still writing code that assumes static TXIDs they really do deserve what's coming to them.

As I see it: the attack reaches critical mayhem in a similar way to accepting zero-conf transactions in that what you have is a consensus problem. The specific fix for TX malleability is to watch transactions based on their meaning, not their TXID (in this case "meaning" is looking at the inputs, outputs, version, timelock, etc to produce equivalent transactions.) And of course: don't accept zero-confirmation transactions.

Here's some of my ultra-1337 Python code for producing the "attack" just for laughs:

def mutate_tx(tx_hex):

"""
Mutates a raw transaction using TX malleability in the scriptSig (specifically, the OP codes.) This function shouldn't be used beyond testing as it uses an ugly eval() hack.

https://en.bitcoin.it/wiki/Transaction_Malleability
"""
tx = CTransaction.deserialize(binascii.unhexlify(tx_hex))
script_sig = repr(tx.vin[0].scriptSig)[9:]
script_sig = eval("CScript([OP_1, OP_DROP, " + script_sig)
tx.vin[0].scriptSig = script_sig
return b2x(tx.serialize())

As you can see, there's nothing to it. Just a clueless attention whore claiming to an even more clueless journalist that he can break Bitcoin.
If cars and all the oil infrastructure didn't exist, EV and batteries are superior. They have far better efficiency and are a much more elegant solution. But all the oil infrastructure does exist and is a huge advantage for oil producing solutions. Consider asking a random person, would you rather keep your current car and use oil that has a side benefit of being carbon neutral or throw away the car, buy a brand new EV, and all the other associated costs (like upgrading the electric sockets in the garage). I think most would keep their car. And for someone living in an apartment without a personal garage, it's not even an option.

If we someday convert our deserts into massive solar energy farms, it may not even matter much that the oil technology is less efficient. There would be so much excess energy during daytime, the greater efficiency of EV wouldn't be a big advantage.

And gas engine technology itself isn't standing still. The traditional ICE engine efficiency of 25% is pathetic compared to the EV 80%. But the Prius combines both technologies and gets 40% thermal efficiency which is a big improvement. It's possible this could be increased further with more improvements in hybrid technology.

Many think that hybrids and plug-in hybrids are a bridge technology to a pure EV future. But the future may end up being a lot more similar to the present than expected. Maybe the typical car purchase in the future will be a 100 mpg hybrid with 60 mile plug-in battery range as an option. Those who have personal garages would buy the option, those who don't would not. And it would be all powered by massive solar power farms in the Mojave desert and wind farms in the mid-west. And the output from all this would be electricity and carbon neutral oil.

If it's so easy why is it the case that well meaning website after website decides to give up? I'll suggest that it's actually quite hard, that trolls and astroturfers will modify their behavior in accordance with whatever rules you put up but they are still not commenting in good faith and will tend to derail and dominate conversation.

practically free energy

We've heard that before, as far back as 1954: "too cheap to meter". The problem is, even if the incremental generation of electricity is practically free, there are still large costs in building the windmills and solar panels. And there are large distribution costs as well.

In addition, the more cheap energy there is, the more inefficiently people will use it. Why bother with things like Energy Star and LEED? Just build inefficient power supplies and poorly insulated buildings. After all, it is "practically free" to heat them and cool them.

Post scarcity energy is a non-starter. Consumption will always increase as necessary. Here's an even more crazy example: just how much bitcoin (or similar) mining would there be if energy were cheap? It's already a disgusting misuse of resources, it would be a lot worse!

Thanks for the reply, but I wasn't intending on visiting the same coffee shop twice.

I'm sure people might assume I'm "up to no good," but that's not something I'm particularly concerned about. No one would really be worried about my appearance in person, nor would I become a regular anywhere.

However, this whole point is probably effectively mitigated with a prepaid data card and mobile hotspot.

You seem pretty confident in your argument that developers are just complaining while using the tool wrong. It makes me think that your experiences in UI development on large teams is limited.

There is a reason why you hear this constant complaint, and the reason is because IB is really horrible in this regard. Behind the scenes it is generating unnecessarily verbose xml that is not developer friendly at all. This is unacceptable. Even Microsoft did a much better job when generating XAML from Expression Blend, and this was half a decade ago.

I'm not sure if you've ever used react-native, but imagine if IB generated ode that looked like a react component. Not a single soul would be complaining because these problems wouldn't exist.

The WantedBy value in the system definition file isn't an absolute (nor are the similar values Wants/Requres/RequiredBy/etc). Instead they are defaults.

What systemd actually does at startup, or when starting services individually, is look for symlinks. If I have a foo.service and a bar.service, and a symlink called foo.service.d/bar.service -> ../bar.service, then systemd will start bar.service automatically whenever I ask it to start foo.service. If it also sees a multi-user.wants.d/foo.service -> ../foo.service, then it will start foo (and also bar) whenever it enters the multi-user "runlevel". (This is almost exactly how sysv runlevels work, except that they're named rather than numbered, and they can depend on each other.)

I can make that symlink manually, if I want, or I can call "systemctl enable foo.service" in which case systemd will read the dependency information from the .service files and make the appropriate symlinks.

If I don't like how the distro or packager has set up the service file, I can override it. The service files live in /etc/systemd/system by default, but systemd also looks in /var/systemd/system for overrides. This is the real reason why systemd uses key=value stores for units; merging them is trivial while merging shell scripts is decidedly not.

Putting the overrides in a separate directory is a pretty nice decision; it's always obvious what changes have been made, and upgrades never overwrite them. I can even put those overrides into version control and track changes to them over time.
Our high school science teacher went to school in the late 1950s.
