Is this the space version of Controlled Flight Into Terrain? All the other mishaps I can recall were equipment failures, barring the satellite collision.
Fused-filament is actually welding because the molten material is the same as the 'base' material. The real problem is shrinkage in going from melt to solid. The same problem occurs in 2-part polymers since they shrink as they both polymerize and cool. (They get bleep-ing HOT during the process!) Some of the other processes (selective UV curing, selective laser sintering) avoid that problem and produce much better surface quality but at the cost of even longer build times and extremely more expensive materials.
Note that Chicago has its own gun laws in addition to those of IL. Some have been struck down by SCOTUS but they are still considerably more restrictive than the state laws.
I did wonder about that, having read that all nerve tissue is light-responsive. What would sunlight do to thought processes? Trans Cranial Optical Stimulation?
One aspect of "accessibility" is certainly the freedom of access, to get a copy of the paper. This aspect is being discussed most and for good reason. A second dimension, less discussed, is readability. Scholarly articles are written to be information-dense and unambiguous, communication from a specialist to another of the same. Writing more broadly readable articles is difficult and really not in the skill set of most science specialists. The more expository translation of a scholarly article will be longer than the original and will take a great amount of work to develop. Who is going to do this and how will they be compensated? I think we need an even greater breakthrough than the Internet for this one.
Rectilinear "pouch" type lithium-polymer batteries are mostly flexible. It's the glass in the display that isn't. Finding another oxygen barrier that flexes is the real breakthrough.
This is centuries-old hat in all kinds of precision equipment. Just think about the slides on the massive old machine tools. They are crisscrossed with grooves and the flat surfaces are flaked to reduce contact and let slide oil help keep the metal surfaces apart.
Whoever launched this as an amazing new discovery should be painfully embarrassed. Don't even want to spend time for links - just search if you're interested.
Spatial light modulators to shape laser beams were big stuff 25 years ago but I haven't seen mention of them for a very long time. Is there really anything new in this work or is it something (nearly) forgotten being rediscovered?
I think it would be an obvious move to have the NSA monitor "our" Congress-critters. Add their staffers, all the top people in the political parties, consulting companies and lobbyists. This is a manageable target size, all composed of people who presume to control public resources. As a group these people have caused more damage than all terrorists put together.
A shock collar might not be sufficient. Seriously, in my considerable experience with this situation the biggest problem is their expecting a quick sound-bite to tell them everything they want. When that fails, as it must, they will blame you.
A second issue is their weak math/logic skills for mentally organizing complex new information. Your one-sentence syllabus is already far too much information for any C-level person to absorb in one sitting.
Rather than trying to be complete and accurate, you should identify a list of simple facts you want them to know. Express each fact in a simple sentence with visceral impact. Emphasize it with a physical prop. Example: "Real-world software is more complex than most people realize." Related prop: Source listing, on paper, of software they can relate to their own work life. (Strap it onto a dedicated $25 hand truck for easy re-use.)
Do not try to paint a big picture, it will just annoy them and they will direct that annoyance at you.
A modestly positioned judge has taken a stand against what most of us here oppose. What can we do? Make noise! Write your congrescritters -- real letters, made of paper. Call your local TV stations and urgently express your desire that they talk this up repeatedly. Use social media to praise the judge too.
If you are going to expend those resources why not pick something more desirable? Bring Lindsey Lohan back to life and keep her/them away from Hollywood, for instance. And whatever happened to the effort to reconstruct the auroch? I'd really like to see them.
Thanks for your informative answer. The din of uninformed opinion really is discouraging.
A follow-on question: by taking the action of cancelling the lease, did the printer manufacturer suggest a precedent of presuming liability for objects made with their printer? Their move seems cautious in this one case but certainly not in the general sense. People, being people, can and will print risky, dangerous, incredibly ill-advised things with these printers. Seems to me that anyone in the business of providing printers, supplies or even CAD files would want a very tall barrier between themselves and any user's results.
One thing the article could have mentioned is that the US has abandoned its capability to build big machines like this. Marion Power Shovel and its peers, who also built the machines to dig the Panama Canal and other historic feats of engineering, are gone. Empty fields here in Ohio where the plants stood.
Thinking about this in juxtaposition to present-day ideas of 'innovation', such as new versions of stupid games for telephones, makes me feel ill.
This doesn't begin to address the transition from subsonic to supersonic, where at some point you must have flow at 45 degrees over both supersonic and subsonic surfaces, stably; the plane would have a tendency to pitch and roll under this maneuver.
Transition was the part that made me wince too. Slow rotation while moving at transonic speed -- Gulp.
OS-X is what Linux could have been if it hadn't fragmented, if it had been properly packaged and supported, if the developers had put some emphasis on ease-of-use instead of "cool features" and obscure options and if it had worked with all the printers, cameras, phones, webcams and scanners that the average user just wants to plug in and have work - immediately and fully.
If Linux teaches us anything, it's that users will pick integration, polish and design over "free" any day of the week.
This is the most concise statement of the problem I have seen to date. Slashdotters deride the Apple way: 1 choice, hardware and software and it just works. Also the Microsoft way: 1 choice in software, many in hardware and it mostly just works. Then there is the Linux desktop way: many software options all about 80% complete, any hardware as long as you can write your own drivers and kernel modules. The total amount of effort represented by all the Linux options is more than enough to have completed several options fully equivalent to OSX if that effort had been focused into several efforts instead of being fragmented into dozens. Why does the fragmentation occur? Because too much of the rewards for an OSS project (feel-good stuff like having fun, seeing your own name on a project) come from the first 10% of the work. Something needs to encourage people to complete the next 90%: the hard parts like actually making everything work right, accommodating all the variety in machines and peripherals. Then there is the next 1800% of the job: maintenance. These are the weak links in OSS.
Projects that work, such as the kernel and Python, have a single person who maintains the vision. This person is able to enlist the help of others to implement the vision. Notice that both of these traits parallel commercial startups. Worker bees in commercial startups are rewarded with wages and stock. What are the rewards for worker bees in OSS projects?

Very well said, Sir or Madame AC!
AC, this is the most cogent statement ever! Fresh out of mod points but you deserve +5 Insightful.

The committee was chaired by a Congress-critter named Church. Nothing whatever to do with religion.
1. Sell empty promises now.
2. Wait for your "customers" to die.
3. No 'Profit!' because you bolted with the money during Step 2.
Look for them to avoid any preview of the avatar,

Keep going back -- look up Whiskey Rebellion.

Smart but misguided, one might say ...
Kudos, AC. That is both the funniest and most insightful comment here.
Poster was talking about traffic signal lights and they can get covered by wind-driven snow.
