Having done a few weeks of highly repetitive work, the worst was when I had to bundle items in groups of 10. I couldn’t think a thought more complex, that repeating song lyrics to myself. When I got a few hours feeding a machine that counted for itself, it was liberating.
Do whatever you want as long as you give them co-authorship.
Neat, but I don’t think a city they can enforce that for online adds, which are probably more impactful these days.
In lew of a hand cranked centrifuge, we installed a Crank machine next to the centrifuge, for “reforming offenders stimulating researchers by teaching them habits of industry.”
You can design a language where you don’t need to generate code to accomplish this.
Other people have python scripts generate C, so having on in the same codebase and language is certainly an improvement.
My question isn’t why this is necessary in Rust. My question is why Rust was designed such that this was necessary.
Because otherwise the compiler team either also needs to maintain a huge amount libraries or cut corners and move things to runtime that really should happen at compile time.
Someone mentioned elsewhere that this allows for compile-time type safety. I’m still trying to wrap my head around how that works.
printf is a great example. According to the C type system, it takes a string and a variable amount of untyped arguments dependent on the content of the string, but that doesn’t actually describe the allowed arguments.
Misusing printf like this
printf("%s", 42);
will get you a warning, but only because there is a special case for printf in the compiler. If you have your own function that does the same as printf, and you misuse the same way, you will find out by dissecting the core dump.
In rust the format string gets parsed at compile time by a macro, which decides the type of each arguments that can than be checked by the compiler. Imagine printf(“%s %d”,…) created a function with the signature specialized_printf(char* agr0, int arg1), it would be impossible to pass the wrong types of arguments.
Now that these tools exist people have gone further and made a library that checks SQL queries against the shema of a running database and causes a compile error if it doesn’t fit.
AARRRRG, that one hurt.
Enriching is about isotopes of the same element.
You know elements? The things that have the same chemical property?
The whole challenge of enrichment is that you want to separate atoms by mass alone, and the difference is <2%. Nobody would build many expensive centrifuges if there was another way.
Memory-safe since decades.
It’s just reference counting with some common sense optimisations. From the website I can’t quite make out wether they disallow cyclic data structures or just leek them, but I’m guessing it’s the latter.
Also the only thing worse than one-indexed arrays (the default) is allowing user defined array start.
I feel embarrased to admit that I had been totally unaware of Seed7 until mere two months ago.
Don’t be, there are so many out there, no need to be embarrassed for not knowing a language that prides itself on lot having fortran style line length limit.
After slogging through vhdl, I personally will not voluntarily use a language that forces me to write out stuff like
end if;
end for;
end func;
when three } would work just as well.
Similar deal with
const proc: main is func
local
# local variables go here
begin
# finally, the actual code can begin
where proc means func void so essentially const func void main is func begin. Just default to const, remove the redundant funcs and allow locals to go where they are used, not all up front, even when they are only used in one branch.
You missed the opportunity to make the strokes of the A be the flags.
Platt amendment 2, here we go
I came up with a kind of clever data type for storing short strings in a fixed size struct so they can be stored on the stack or inline without any allocations.
C++ already does that for short strings while seamlessly switching to allocation for long strings.
It’s always null-terminated so it can be passed directly as a C-style string, but it also stores the string length without using any additional data (Getting the length would normally have to iterate to find the end).
Also the case in the standard library
The trick is to store the number of unused bytes in the last character of the buffer. When the string is full, there are 0 unused bytes and the size byte overlaps the null terminator.
Iirc, that trick was used in one implementation but discontinued because it was against the standard.
(Only works for strings < 256 chars excluding null byte)
If you need a niche for allocated string you can get to 254 but the typical choice seem to be around 16.
In my opinion bicycles should not have a high beam, but here goes:
Look inside, do any components look fried?
Can you get the led to light by applying the a low voltage with a current limiting resistor directly to it? If I don’t know what to do with the circuit I would probably go outwards from the desired results.
I don’t believe you could save the emissions from animal agriculture.
The easiest is to stop converting more land to animals use.
Most animal ag is on land that isn’t suitable for growing crops,
But 6% of global emissions are from feeding crops to animals.
if it was ended, the land would become useless
Aside from reducing our emissions by 16%, meaning it would be about as useful as removing all emissions from the transport sector.
and left to go wild where it would support just as many just as polluting animals,
Laughable, but if if it where true it could easily be solved with reintroducing predators and rewilding the artificial grass lands.
but with no possibility of treating the pollution problem as no one would be managing the wild animals
What is more polluting? Animals shiting in the forrest every day at a different place or month worth of stored manure deposited on one field in a day, with barely any plant at the moment? Which of those will naturally break down and which will be washed into the ground water?
Where are the huge amounts of biomass fermenting into methane? Some swamps and every farm.
Where is the source code?
You can’t make any claims about privacy without it.
I had the same question a few hours ago, but I found some science.
Tldr: 30% of energy use is in diesel, and about half of that is for tilling fields.
Rant:
Note that this is energy use, so only CO2 emissions are counted, while methan is ignored. If we stopped farming animals, the effective emissions of the sector would be cut in half. Even if we are unwilling to change out diet, maybe we should look at reducing the amount of fertilizer instead.
I can hike for 12h with a big backpack, but standing for 8h is horrible.

The main problem is that, not ploughing increases the need for pesticides, currently around 8% of energy used and reduces yield. While not ploughing increasing requiring 3x the pesticides might not be the case, a 20% reduction in yield seems plausible.
The main energy consumption in farming is fertilizer at around 50%, but more importantly half the emissions are related to animal agriculture. Cutting back on that would actually make a difference.
Don’t trust us until you are here!
The government is defying the supreme court, by refusing to provide visas for people, that are thoroughly vetted and helped us against the taliban on the condition that they get visas.
It’s either printf and stack unwinding in assembly or something to test all possible execution path for very simple multi threaded programms.
My guess:
The kidnapping was arranged with some insiders in Venezuela. Why else would the US accept the vice president backed by the same powers that backed the president?
Trump wasn’t told this, instead they made up something stupid to explain why it worked so smoothly. Trump is incredible uninformed, remember when a reporter showed him the video of the first ice killing and he hadn’t seen it before despite arguing about it?
