A Bid To Take 3D Printing Mainstream

leftover Re:Yet Another Crap Extruder (143 comments)

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.

Could We "Wikify" Scholarly Canons?

leftover "Accessibility" has multiple dimensions. (63 comments)

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.

The First Phone You Can Actually Bend: LG's G Flex

leftover Re:Battery (92 comments)

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.

US Nuclear Weapons Lab Discovers How To Suppress the Casimir Force

leftover Prior Technology (112 comments)

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.

South African Research Team Creates World's First Digital Laser

leftover Rather long in the tooth? (81 comments)

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?

New Snowden Revelation: Terrorists Attempting To Infiltrate CIA

leftover Better use for NSA capabilities: Watch Congress (250 comments)

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.

Ask Slashdot: How To Teach IT To Senior Management?

leftover First, get their attention and commitment. (159 comments)

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.

National Security Letters Ruled Unconstitutional, Banned

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.

Over-reach, just a little.

leftover leftover writes  |  more than 3 years ago

leftover (210560) writes "A report from no less than Stanford has concluded that "digital health care records" don't improve care. Hopefully this is a case of ignorant reporting rather than ignorant research. All "digital health care records", really? All methods of incorporating digital technology into healthcare? Or is the single method they tested the Only feasible approach. This crap reporting matters because it will be absorbed by people in general and Congressional representatives in particular. As usual, any clarification will now need clarification/elaboration effort greater by at least O(2). (Can you tell I'm happy about Knuth v4A?)"
