Interesting! First thing that came to my mind was "Two flat layers of one substance with another flat layer pressed between." This works for food but also for non-food, sandwich transistors for example, or when you get sandwiched between two Finnish dwarves. But of course this use of sandwich came after the original use which was the food item, and "sandwich" nowadays can mean "something resembling the structure of the sandwich food item."

The idea of an "open-faced sandwich" is particularly interesting. It's like sandwiches became so common that the part of definition about two pieces of bread was no longer important - it is a sandwich because it looks like a sandwich. And if it's missing the top piece of bread well then it's a sandwich that's open. Weird. Is that like a one-hand clap? Or a four leaf clover with 3 leaves? Or related to the fact that I'm half-centaur and my girlfriend is half-mermaid?

Reminds me of a nearby mountain called Forbordsfjellet. "Fjell" = mountain, and Forbord is the little village in front of the mountain. So far so good: Forbord's mountain. But "forbord" means "before the foot of the mountain." The village was named for being at the foot of the mountain, and then the mountain was named later after the village. Before-the-foot-of-the-mountain mountain. Weird.

Sorry - don't want to hijack an awesome discussion about sandwiches with Norwegian mountain names, but this feels connected to open-faced sandwiches somehow.

Deep in vacation mode. Bought myself a used acoustic with a pickup, so had to get an amp and a microphone. The salesman talked me into a Fishman Loudbox Mini. I should buy that guy a beer. This amp sounds great, looks great and is a lot of fun.

Started a new art project - haven't done art in about a year and it feels great. Goal is to make 20-25 cm models of the 5 Platonic solids, each made from 6 human figure shapes. They'll be 3d printed in metal. Making 3d art is 10x harder than 2d, my 2d pictures I can cheat and hide things, but a 3d model that people can handle has to be perfect from every angle. This will take me all summer and maybe beyond.

Going to Greece on Sunday to sit on an island and do nothing for a week except eat well and drink adequately.

Are you looking for a fast buck or a long-term investment? If you want to be a trader and flip the coins to make some quick cash it's a pretty dicey time for that and play at your own risk. If you want to invest and hang on to it for a year or two then it's a good time to buy. kleinbl00 has some great advice -- especially his point that anyone giving advice should be sure to include: invest knowing the price could go to zero. When I buy I always expect the price to drop right away and it doesn't bother me when it does.

Here's some advice I posted on cryptocompare last week:

You can be a trader or a holder. Trading is very stressful. When the price is going up you don’t want to sell because you’re sure this is “the big one.” When the price is going down you don’t want to buy because you’re sure it’s going to go even lower. You miss the top point. You miss the bottom point. You feel like you’re wrong about everything. You can make money on it (and we hope you do!), but it’s pretty damn stressful.

Want less stress and less risk? Commit to medium- to long-term holding — you’re probably going to do well and won’t need to be worried when the price jumps like crazy like it has been.

Here’s my advice for my fellow holders:

1. Pick the price you want to cash out at and decide on a reasonable and slightly pessimistic time frame that you think it will take to happen. Maybe $1000/eth is your goal and you figure it will happen at the end of 2018. Great! Whatever happens between now and doesn’t really matter.

2. Don't feel like you've "lost money" every time the price drops. It’s a powerful psychological effect you need to be aware of and fight against. You don’t lose money unless you cash out at less than you bought for. If you bought for 100 and later watch it drop from 400 to 200, you have haven’t lost 200/eth, you’re 100/eth ahead. Yeah, you could have sold at the top, but you didn’t. That’s ok, stop kicking yourself. Just wait. And if eth is worth less now than when you bought it, realize that the quick buck you hoped you would make will just take a little longer. Eventually you will see rewards on your investment, and the rewards will almost certainly be at much higher percentages than you find elsewhere.

3. Ether will surprise you, good and bad, but it’s still on track. When ether jumped from 10 to 50 earlier this year suddenly it was “game on” and there was a lot of talk that it would go to $550 by the end of the year. That seems very reasonable, still. And we can expect to be surprised again and again.

4. There’s lots of talk about ICOs cashing out, draining the buyers and sending the price down. That may be, but then that means that there’s a lot of talent that are now very motivated to go out and make many many fine products that will use ethereum. Within a year we’ll be seeing user-friendly ether browsers and dapps with exciting functionality, all of them running on ethereum and using ether. When that happens, your ether is going to be worth a whole lot. Think of the price drops now as paying in advance for to be able to realize the ethereum dream. And then not only will you reap the financial rewards, but the world will have some great tools.

5. Obsessed with the ups and downs and wishing you were taking advantage of them? Try a little day trading with a small percentage of your ether. If you play around with 2% and lose a quarter of that in bad trades you’ve only lost 1/2%. And if you guess right it’s fun to earn a free dinner or a free vacation (depending on how many ether you’ve got). But keep a chunk of ether reserved for your target price and don’t touch it.

6. Enjoy the ride! As a holder you can laugh when you the price drops and you say “I just lost $X today!” You can also laugh when your friends say “The price is all the way up to $Y, why aren’t you selling?” Nope. Let it ride, relax, and enjoy being part of this experience.

Wicked cool. Mac lets you set it as a shortcut. I just can't stop toggling now!

Lots of good points there. goobster makes the point about what vehicle safety inspections look like in Europe and Scandanavia. I live in Norway, where as he says the inspections take over an hour (and cost about $80). We don't have to be able to diagram engine parts for our driver's licenses, but it's not easy to get one. There are different requirements for immigrants based on the the country you're coming from. I got off easy because I moved from the US with a valid driver's license. I only had to take a 45 minute road test.

One problem with Norwegian driver's licenses -- they are valid until you're 100 years old, although you have to a driving fitness test every 5 years starting at age 80. My driver's license expires in 2068.

Possibly! The environment changes and species go extinct - I reckon we'll see quite a few disappear as the planet warms. I don't think is necessarily a bad thing. As species disappear, new ones appear and thrive in the new conditions... so it has gone and so it will go. Homo sapiens will one day disappear as well, I just hope something smarter takes our place!

In my country, tipping is limited to rounding up a few cents to the nearest 20 or 50 crowns. Servers make good salary, they make what they're worth without having to busk. The customer is not expected to directly pay their wages. Servers are good servers because that's their job and they're professionals, not because they're hoping to get extra reward for doing the job they're being paid well for already.

My unpopular opinions:

It is a good thing that some species go extinct.

Genetically modified foods are generally a good thing.

The EU requires vehicle inspections every 2 years. We all grumble every time our EU-kontroll comes due but dutifully take our cars in to find out there's a light burned out and a shock-absorber that's worn. We pay up, people complain but generally agree that it is nice to know that your car has everything fixed and every other car is in good condition. I actually like getting everything fixed on my car every two years.

Folks that don't like the inspections quote the studies that say required vehicle inspections do not improve safety. But that doesn't seem to make sense. Google will give you stats favoring both side. I do know I see almost no cars broken down on the road, which I used to see often when in the US. How do cars on the side of the highway affect safety, both for the driver and passengers of that car and of the other cars? It is not zero.

The question seems to be of cost-effectiveness: what is the cost of these inspections vs. the costs of repairs after failure/accident, hospitalization and funeral expenses related to vehicle failure, and is it worth this cost?

Love it! Well done.

Spent the morning at the nearby highschool (there aren't many nearby highschools in rural Norway) where I'm allowed to play with their laser cutter. Only my second day on it, they've used it only for glass engraving so I'm the guinea pig for cutting plywood. Got some good results today but plenty to learn. I'm prototyping puzzle pieces that will become products - fun and exciting work.

My secondary goal is to develop a clean workflow to go from Sketchup Make to a laser cut piece in the correct size as designed in SU, using freeware programs like Vectr and Acrobat. I can't use Inkscape because it cheats and doesn't export vector graphics.

What software do you use?

I've been reading this, digesting it slowly over several days and loving it!

The author says you need to read all 6 chapters to get up to speed just to understand the amazing project underways. I'm on chapter 3 now and getting a feeling for where this is going...

Very clever that BM (for bone marrow) written in Braille and turned upside down is your company logo. You guys thought of EVERYTHING!

Seriously awesome guys. Been a follower since day 1. I already have a bag of stem cells in a freezer in Norway. I like to think of a magic potion, ready to save my life (again) someday!
