I wish people would gamble with something other than a proof-of-work coin. There are very similar alternatives now. When bitcoin rises, more money is spent on mining. Whoever holds bitcoin is in part responsible for this waste of energy.

Orange oil works wonders. It's explicitly not food safe, but you get that stuff on your hand every time you peel an orange and it's also present in juice. Just rinse them afterwards and wear gloves.

Sure if you are already airing every hour you don't need it. Then for me it was surprising how often I have to air and for how long (also depends on draft and temperature difference). Once you take into account the more harmful particulate matter coming in from outside, it's about finding a compromise, and without measuring you are tapping in the dark. But in the end people get old without all that stuff.

The professors I know are experts in their small domain (and most of them are really smart, but this is not my point here). They know all the nitty details, I am always amazed by their wide knowledge in discussions. I think for a society it is easily worth it to pay people to dig so deep into their field of interest and the market is not the right mechanism to enable that. I also think Youtube is nice to get started, but I found it insufficient for graduate level material.

Yeah, you only ever hear the naysayers. So second voice to combat that: I like the integration and use it with (admittedly few) selected friends to split bills. And I think it fits signals mission.

Would you expand a bit on the shortcomings? I'm under the impression artificial life was an attempt in the 90s and after some disappointments fizzled away. Why is simple copying with mutation not sufficient for real evolution? In my naivety I hoped it would lead to digital evolution finding exploits to proliferate across the internet.

In Germany, there is an account people can donate money to, to reduce state debt ("Schuldentilgungskonto"), without any personal benefit. It's not even tax deductible. I think that would qualify to refute your last paragraph. It's not used a lot, though. 1.33M in 16 years.

If it comes to that, I expect manufacturers to design processors in a way that electromigration limits their lifetime.

Maybe take a look at evcxr, it runs in a terminal and is REPL like. When I'm dabbling in rust, I use it e.g. to quickly try out library functions and how to work with the result. But I'm just getting started.

Is it just about a REPL? There is the evcxr hack, though I'm not sure how far you can take it.

The paper packaging of Wasa has a thin plastic liner, which you can see stretching by slowly tearing the paper. It is probably better that the thicker FinnCrisp plastic, but Wasa paper does not belong in the paper bin for recycling.

I learned something, thanks. One of Chen's arguments is, that C allows better memory control compared to C++. For example, it's easy to place the vtable in pageable memory instead of non-pageable memory. Do you know if rust has this problem too, since it also uses vtables?

To quote their FAQs:

>Is it firesafe?

>WikiHouse is not really any different from most kinds of 1-3 storey buildings with timber roof, floors, or internal walls, in that the building needs to be designed with adequate means of escape, and the chassis needs to be reasonably protected from catching fire. This can usually be achieved either with a plasterboard internal lining, by using a non-toxic fire protection coating, or by installing a basic sprinkler system.

>If you are building several adjacent houses, located close together in a row, you will usually need to use an external fire barrier material to prevent fire spreading from one building to the next.
