My experience is that it is much more a matter of architecture. This is a lock free key value store in a single file - it doesn't have the network protocol, but any threads dealing with the network IO could use it without doing anythin

This is completely untrue to the point of being the polar opposite of reality. Look up the attributes of ideal money. Gold and silver are the original currencies. They are trustless because they can be verified easily and transferred phys

Those were influential and have a had a very positive effect on modern C++ without a doubt. Now that they are part of the standard though there are fewer reasons to use anything from boost, largely because it is a double edged sword of com

I'm sure there are good parts to boost. I have no idea what they are, but just by sheer quantity, something must be worth using.

Prefetching is another technique. If memory is accessed linearly, the CPU can prefetch ahead of what is currently being accessed, and that will include the TLB lookups.

I was already assuming that concurrency was a big part of that statement. I respect Rust's attempt to solve these issues at the language level, but my experience has led me to think that they need to be solved at the architectural lev

I'm not sure an anecdote about about a software project failing twice and succeeding on a third try can be used as evidence the the language of the third try enabled something to be pragmatically possible. I'm sure rust helped, b

I don't think there is anything that Rust can do technically that wasn't possible before. I think it's benefits are more about implicit organization.

Requiring trust is not a positive aspect of currencies. Gold and silver succeeded in large part because they can be verified.

The same extrapolations happen with population density. People in LA and New York think the world is overpopulated and everyone is on top of each other. They don't realize that 45 minutes north east of San Francisco there are no hous

No it isn't, flash was the best way to do many things for the years it was popular. Video, vector animation, simple interactivity. Electron is only the best way to do something when someone knows only javascript and web dev but doesn&

Not only that, but it isn't clear how many kids are in private schools, or even what the demographics are of both groups.

Your post that I replied to said that no governments wanted free energy, now you are shifting the goal post to some sort of further made up hypothetical world where big governments have free energy and small governments don't.

by AboutTheWhisles 8y ago
Wouldn't that imply that less powerful governments would want unlimited energy to become less dependent on richer and more powerful governments?

It's not what you know, it's what you can prove.

Exactly - if you could copy and paste a function, having it as a full library dependency is insanity.

SQLite, which is a single 6MB .c file compiles in under a second in any compiler and under 0.01 seconds with tcc.

You can mitigate the reading from disk by memory mapping the file. I don't think serialization is a problem either. It is possible to make data structures that always exist as a single span of memory, so that they don't have a se

I'm not clear which scenario you are alluding to. It the expectation figuring out only how to sparsely sample the same area or how to quickly sample the larger area so that a detailed scan can be taken after that?

by AboutTheWhisles 8y ago
How are they expecting 'faster' MRIs from this? Are they searching for a way to hone in on the important parts to take more detailed scans?
