To everyone thinking about using caffine or other drugs to combat sleep: all of the latest sleep reseach would suggest that 'optimizing alertness during sleep loss' is a fool's errand if what you want is productivity. The rea

Theres an @. macro that will broadcast all the following operations. ie. exp.(v.^2) .+ (10 .* u) can be written as @. exp(v^2) + (10 * u) with no added runtime cost.

:shrug: I don't have to recompile a julia function every time I run it so long as I don't close my julia session. If I do need to close and reopen my julia session a lot for some reason, I'd just statically compile the funct

To be fair, the majority of the stackoverflow questions on how to speed up julia are from people brand new to the language coming from Python or whatever. Its relatively easy to optimize julia code, but I think its understandable that someo

I'm not knowledgeable on this topic at all, but I can tell that the bulk of julia development hasn't involved a lot of thought towards web technologies. So I wouldn't be surprised to learn that the infrastructure just isn&#x2

I can see how one might naïvely think that, but in my experience and the experience of everyone I’ve talked to who uses julia, gradually improving the performance in your bottlenecks using only Julia is much nicer that just working in C or

> The biggest issue with the standard Julia benchmarks is that they're not using what would be optimal C code to compare against. Yes, the C code benchmarks are not optimal. Neither are the julia benchmarks or any of the other langu

Theres a discussion on that post in another thread below, but suffice to say the julia community is pretty exasparated with the constant need to respond to that post when its main source of the speed claims was to measure the perofrmance of

this discussion [0] showed up recently on the julia forums regarding what julia pacakges can be considered 'state of the art' ie. just don't have equivalents out there in other langauges and there was some interesting discuss

For what it's worth, I got involved in the Julia community about a year ago and people have been nothing but friendly to me and toleant of my sometimes excessively dumb questions. I don't doubt that some people have gotten into na

That is absolutley false. Look closely at the 'benchmarks' shown in the above article and tell me if they are at all compelling. They measure Julia's startup time and compilation time. IF you wanted to compare Julia to C ther

To be fair, ownning an iPad Pro, I can say first hand that the handwriting recognition possible with the stylus is actually quite remarkable and a great improvement from the old palm-pilot days.

Doesn't seem to really take advantage of Julia's compelling tools but still neat.

Haven't read his book but I've listened to him talk on podcasts. I think he makes some excellent criticisms on the horrible state of dietary science. He can be a bit digmatic himself and sometimes makes unhelpful statements but he

Julia has much better support for functional programming.

Any Dirac 4-spinor can be formally decomposed into two independent Majorana spinors, so yes a Majorana spinor May be thought of as half of a conventional Dirac spinor. On a 1D lattice this manifests itself in that one can formally decompose

It’s been painful having that older blog post show up as one of the top items when people search for Julia. I know The first time I got interested in Julia I was turned off by that article and it wasn’t till I came back later and started th

I think it’s hard to argue that the original article was valid when it’s opening argument was as far as I can tell, a deliberate attempt to misrepresent Julia’s performance.
