Sounds like it could be optimized to run 10x faster on a single thread. ~7MB/s is not that fast

It makes perfect sense when writing and reading strings from disk, since you don’t have to worry where and how to store the integer for the length (#bytes & endianness)

Using GNU make you can get very nice output sync: all: variant-1 variant-2 @echo done with all variant-%: @echo starting $@ @sleep 1 @echo done $@ Use `make -j2 --output-sync=target`.

> but I don't think any language is going to offer that out of the box. That's what compilers are for. I tried to improve the C version to make it friendlier to the compiler. Clang does a decent job: https://godbolt.

The title I/O is _no longer_ the bottleneck seems to suggest disk speed has caught up, while in reality the slowness is due to poor implementation (slow Python or Go with lots of allocations). The real problem to me is that languages a

Is the 2022 in the bound there cause it's sharpest or because he happened to have the freedom to pick it equal to the year of publication?

I guess it won't work for rich editors that create tons of elements for every style applied, like `<b><span style=font:...><span style=...>...<i>...` it requires some sanity of the editor.

sudo feels like a broken concept to me in general. sudo make install, ok, great, some of the many operations you need to do requires privileges? Better give elevated privileges to all operations! Even worse with GUI: enter your password t

Even a 2x faster Python still makes a terribly slow language. Improvements look amazing relative to old Python. But compare it to PHP, Javascript, Lua. Ok, it might be better than Ruby sometimes.

Another nice tool is the Julia repl: julia> 1.4 + eps(1.4) === nextfloat(1.4) true julia> bitstring(1.4) "0011111111110110011001100110011001100110011001100110011001100110" julia> bitstring(nextfloa

My guess: in C++ it's templated and header-only, which means optimized hash table code gets generated for the types you use it for, and you don't pay for it in binary size when you don't use it. In C you get stuff like qsort

> I opted for a hash table, as conveniently implemented by glib, which QEMU already depends on I wonder how many C projects use linear scans instead of hash maps simply because C doesn't have it in its standard library.

You're not talking about shuffle, you're talking about broadcast. Shuffle instructions is where you take one or two vectors, and output a third with elements from any index of the input. So for example `out = [in[2], in[1]]` is a

On a related note, I feel that some websites at are a point where they're complete, and adding new features makes the experience worse. Take Github: to me it feels that it's now at an optimum where adding new features that make it

The optimization is under -O1 in gcc, and can be turned off with `-fno-merge-constants`. However, if you use lld as a linker, strings are duplicated by default. To merge them, you need `gcc -O1 -Wl,-O3 -fuse-ld=lld`. So, it is a combination

It doesn't require sudo install, you can just download and extract it and you're done.
