It was a black website with white squares laid out in a grid. Each square was a different musical note, and you could click and unclick different squares to change the melody as it looped. It was extremely relaxing to me, and I can't seem to find it through google searches.
Still relatively new to Chicago, whenever I've made that journey I've been slightly terrified due to the high traffic volume paired with inadequate bike infrastructure. Is there like a pedestrianized bridge along there somewhere that I've missed?
Edit: Thanks for ideas, I particularly liked crossing on Damen. Will try out the other suggestions in the future!
Just curious. Anybody else? Just started.
Everybody knows that binary logic gates form the basis of CPUs. Everything else is just unoptimized garbage. So obviously, it stands to reason that coding in purely binary logic would lead to the absolute fastest code you've ever seen in your life!
Here's a function for computing the square root of an integer:
def add(a,b):#a,b>=1
while b:
a,b=a^b,(a&b)<<1
return a
def sub(a,b):#a>=b
m=1
while m<a:
m=add(m<<1,1)
b=b^m
return add(add(a,b),1)&m
def sqrt(n,o=None):
if n==0:return 0
r,s,i,u,j=n,0,0,n,0
while u>=4:
s=s<<2
u=u>>2
j=add(j,1)
while i<256:
if r>=add(s,1):
r,s=sub(r,add(s,1<<(j<<1)))<<2,add(s,2<<(j<<1))<<1
else: r,s=r<<2,s<<1
i=add(i,1)
if o: return s
else: return s/(1<<257<<j)
guys its totally optimized trust me its not like a module exists for this
Marine here, asking because I’m curious.
I have built on-the-move NVIS loop antennas (horizontal square loops) that have everything correct except the real estate (due to being vehicle mounted). Impedance, VSWR, scores, LQA, etc, all are where they should be.
However, after doing some tests on both the 80m and 40m wave lengths, not getting very far for NVIS shots.
I am suspicious it’s due to the fact I’m taking a small portion of the real estate I should be. For example, let’s say I had 4.5225 MHz, and in order to mount it, I’m taking a quarter wave (51.7 feet of wire-shouldn’t matter too much, however because my HF assets can self-tune) and coiling it into a 3x3 square foot FEAK build made of PVC pipe. When I do that, I’m really just looping the wire into a tight box that “technically” propagates with NVIS, but I’m only hitting 10 km or so away. The loop has me winding it into this square several times around.
Instead of looping around such a small box, what if I coiled the wire tightly instead? Imagine a corded phone wire that is coiled and I only need to do 1 loop due to how tight I’m able to coil the wire.
Would this help my propagation? What else can I do to really get my propagation where it should be?
