Even when the country gov is hostile to USG, the citizens will still use USD. Citizens use cash, USD notes - not USD bank accounts. No bank accounts are involved. The relations between USG and the local gov bears no consequence to the use

Done that. As a store of value - USD has lower volatility than BTC => USD wins as a store of value. As a medium of exchange - USD paper notes are more convenient to work with (on balance) => USD wins as a medium of exchange. Hence - p

Yes, agreed. I understand what you mean. I grew up in "in Europe but not quite european" country. I hope at some point e.g. BTC version 23 is going be as convenient to use as is a credit card - no need to DL 300GB, wait 10 mins fo

Indeed everyone holds non-local currency too. I'd presume USD and/or EUR have taken on the role of "store of value". I lived through collapse of a state 30yrs ago, and exactly that happens: locals refuse to hold the loca

+1 on this, you nailed the issues exactly! Bad fiat currency is simply a proxy for bad state, bad government, bad governance. USD is safe and sound as long as USA and USG are. Would reuse tax-based and fiat-crypto - you got that right too -

Then you are going to drive 150 miles and spend extra 3 mins to change the battery again - no? Not a big deal, and certainly not a deal breaker. Nah - the pit-stop type battery replacement is the obvious solution to most EV charging problem

"Succinctness is power" is illustrated nicely in the array/matrix languages. Code working on time series - switching away from a matrix language seems to increase code size by a factor of x5 - x7 times. It is mentally taxing.

Not sure if it is possible to have "only valid object exists, ever" and have it working for real. In pointers we have NULL to signal "not a pointer". In floats we have NAN to signal "not a number". In integers

Prompted by this thread, I went to the (slight) hassle of compiling the latest octave (and installing the dependent libs along the way). What a pleasant surprise! I remembered ancient versions (maybe v3?), and it was a (very) poor relative

Ha-ha-ha :-) - too late! Every generation will make their own "Worse is better" mistake. Have faith (and patience), what works and is good, will (eventually) be re-discovered.

Would like to try it at some point. I am trying pandas now b/c other people are using it. So far - the more I learn pandas, the less I like it. Not a good sign. I keep finding things that annoy me in pandas, b/c have seen them sol

Agreed it is mostly used interactively in the IDE. FWIW one can compile into p-code (=underlying virtual machine), package the p-code files of the application with the matlab standalone engine+libraries (MCR), and deploy using standard shel

In the opposite direction, being away from matlab, I notice an upside to "vectorise everything" seems to have been "code shrinkage". Looks like ~3-5x times compared to "code with loops". I often find myself ill
