She's a sometimes model whose non-modeling job also involves looking very professional. I'm not even allowed to look at the laundry for fear of destroying something by washing it wrong. She bought a ... shirt? blouse? I dunno, something you wear on the upper half of your body, the other day, and I was all "that's very pretty!" and she's all "it should be. It cost 800 euros." So, yeah, I don't go anywhere near her clothes. And clothes like that don't have pockets. It ruins the lines/aesthetic. Definitely not something Woz considers, nor would he have any reason to, but there are a whole bunch of people who do.
Even her painting-the-house pants have these microminiature pockets that you can fit, like, a credit card and a car key into. Whenever we go out I carry her wallet, because even that doesn't fit. Totally different clothing regime from my ten-pocket dungarees, where I could carry most of a toolkit for doing bicycle maintenance and still be able to sit down comfortably.

There aren't any current cellphones that fit in the pockets of the sort of clothes she wears. Size zero/one fashion clothing often doesn't even have pockets, much less ones that'll fit the half-tablet-sized cellphones these days. She had an HP Veer, the size of a credit card, that she loved, until it died. So now she has the same smartwatch and has what she calls a GIANT cellphone in her purse or stuck in her desk at work, and takes calls using her watch.

Size zero clothing is probably not on Woz's radar, but there are people who want tiny connectivity.

This is currently what I'm struggling to find. The main thing I've established is FreeCAD just isn't ready yet - very buggy and I can not get it to work, but parametric modelling is an interesting concept.

What else are people using for dimensioning parts which need to fit together? (i.e. part design, rather then modelling I guess?)

I've been using freecad, personally. I just did a series of adapters that allow me to attach RC servos to LEGO bricks for some inverse kinematics robots. It worked reasonably well. I've had it crash and do unexpected things, but what I've found is that if I work in the part design toolbar, build sketches that are fully constrained, and then use extrude/pocket operations to build my final parts, it seems pretty robust. Then I can switch to mesh and turn those into exportable meshes individually, and get parts that interact the way I want to. Half the stuff I'm doing I 3d print and the other half I mill on my cnc mill, and when I'm processing stl's I find again that having started from fully constrained sketches means the stl's are more robust and less likely to crash the cam programs I use.

1. Go into debt to obtain college degree
2. ...
3. Profit!

So, all this time, step (2) was "figure out a way to do it"!

Time to revise:

1. Identify a career that pays well and that you would enjoy spending your waking hours being devoted to. (Until you are certain, live at home, work at some crap jobs, and save money while you figure these things out. Take at least one community college or cheap online course year-round and at all times to maintain your study skills and knowledge base. "Undeclared" full-time college majors should be reserved for children of millionaires.)

2. Identify the lowest cost educational providers that provide quality training and education. (Starting at 2 years of community college followed by 2 years of state college should work just fine for 80% of us. Living at home while attending college should be an option if you live close to good inexpensive colleges.)

3. Work while you are in college to pay what you can and minimize borrowings. (College students who are also working can also often apply classroom lessons to their real-world experience. By not living in an "ivory tower," the lessons are integrated and retained instead of being forgotten after an all-night cram session before the final.)

4. Graduate with reasonable debt and start on a great career and great life.

Not even remotely accurate. Check out the chart at and you will see that while manufacturing employment is on the decline, that Professional Services (including tech), Health Services, Leisure & Hospitality, Financial Services, Government, Trade, Transport, and Utilities have relentlessly grown over the last 40 years.

At the height of the Great Recession (2007-2012), the unemployment rate for people with technical and professional degrees in the US never exceeded 4.5%!

One problem in the US is that our policies discourage risk taking and entrepreneurship. (Single payer college education and healthcare would go a long way toward helping gin this area.) Another problem in the US is that our tax policies insure the biggest corporations hoard cash instead of investing in growing jobs FASTER. A third problem in the US is that we do not treat immigrants with the respect and dignity that future taxpayers deserve.

All are fixable problems. I don't know if we actually fix them. But the solutions are right in front of us.

My guess RFID. By one regular pod, cut RFID chip out of it, tape to the bottom of subsequent generic pods.

FWIW we tried that with our Stratasys 3d printer. It remembered the RFID number and remembered that the print cartridge was out of print material, so sticking the rfid tag to a new, third-party, 1/4 the price, filled to the brim container of print material did precisely nothing for us. I have no idea if the keurig will do the same. Oh, it was also a pain in the butt because they'd built it into the side of the cartridge, so when we cut it out it wouldn't simply stick on the new cartridge as it had a flat side and the resultant cartridge+rfid tag wouldn't fit in the printer, so we had to bodge something up by putting it on the front where the door closed and hoping it would be detected. It was, but see above.

Why not simply lower the water pressure by 10% to curb water usage?

I dunno about everywhere else, but where I live -- next door to the local water tower -- there isn't any sort of water pressure regulation mechanism. You pump water into the water tower, and it flows by gravity to all the houses that are lower than it. And, in the summer, when everyone down in the valley is running their sprinklers, my water pressure is low enough it's difficult to take a shower, so even if you did manage to regulate pressure it would have a disproportionately large effect on some of the people and very little on some others.

This is purely anecdotal, but the two indie framemakers I know who have worked with 3d printed lugs have both said the lugs broke very quickly and they only used them for prototypes, didn't consider them safe to ride. One said he thought he could make a 3d printed lug (this was stainless steel, through shapeways, silver-soldered to Reynolds SS tubing) that would be durable but he guessed it would weigh about 4x as much as equivalent forged columbus lugs.

It's the same as how Congress's approval rate is extremely low, yet in the last election most seats didn't change hands. In both cases, people are saying "everyone else is the problem, not me!" -- they said "vote out your incumbents" but still voted for their incumbents claiming their incumbent isn't the problem.

What makes this complicated is that I think that's a reflection of America. My congressman _is_ a really good representative for me: he's a smart gay liberal who has started several successful tech companies. I vote for him because he's doing stuff I like. My aunt's congressman is a good representative for her: a pro-life, pro-gun conservative creationist pastor. She votes for him because he's doing stuff she likes.
We'd like to think that there's a logical disconnect between "congress is crazy" and "my congress person is awesome" but that's not necessarily true: we, as a country, have an extremely wide spectrum of opinion. Jim Hightower used to say there's nothing in the middle of the road but yellow stripes and dead armadillos. If congress is a dead armadillo, midway between what I want them to be and my aunt wants them to be, my aunt and I can both be contemptuous of congress while liking our personal representatives, and both of us can be logically consistent in doing so.

Lactose intolerance is complex. The Tuareg of Saharan Africa have lower lactose intolerance rates than Finnish people, for instance. It mostly has to do with whether a group has spent a long time as nomadic herders or not, and adult persistence of lactase activity appears to be caused by several different mutations, that arose spontaneously. has a nice list of adult lactase activity in different ethnic groups.

Pure speculation, but it could very well be a knock-on effect from off-shoring manufacturing. You want at least some of your engineers to be close to the manufacturing line to debug when things go wrong. The designers might stay in the US, but manufacturing, test, packaging, etc., will shift towards the factories. And then, some years later, you'll want the designers to be near the mfg/tst/pkg guys to allow easier communication.

It's exactly this. You want your chip designers to be working right next to the mask layout people because layout needs designers to correctly optimize the layout. You want your test people to be able to walk through the whole test program design with the designers, who will be involved throughout the test hardware and program design, because test engineers know how testers work, and designers know how the chip works, and matching those is tricky. And you don't really want to be shipping tested wafers overseas for packaging and then waiting for them to come back to test packaged parts, and the product engineers need tester access and parts access to characterize the parts and produce the datasheet info, so at that point you have the whole silicon design team, from conception to finished parts, in one place. It can be done remotely but with a significant time adder or lots of evening/midnight phone meetings. It's easier to separate applications and project engineering from the design/manufacture group, but there's still some value in having them colocated. At that point, all that's left is middle management... and that's even easier to outsource.

If private organizations can't use drones to help with natural disasters, such as those in Colorado, how do you suppose this will get approved to fly near local airports and various cities and towns won't outlaw the flying of drones?

Of course, there's always the question: How do you deliver to high-rise apartments and other high-density dwellings?

During the Colorado flood, the area around it was under temporary flight restrictions, as determined by the FAA, and no unauthorized aircraft were allowed to fly in it.
While TFR's are getting vastly more common as every penny-ante promoter wants to make every event seem so big it needs special FAA protection to allow it to run, the reality is that 99% of the time, 99% of the airspace is available for private and commercial air operations.

When you don't know what you are doing, do it neatly.
