Compass grid mixin generating over 16,000 characters of CSS - sass
Today I installed Compass and thought I'd try to generate a grid background to help me line things up.
I checked the docs (http://compass-style.org/reference/compass/layout/grid_background/#mixin-grid-background), and it couldn't be simpler, all I need to write is:
body{
#include grid-background;
}
and SASS will produce the correct CSS. My terminal told me everything had gone to plan. Great. I go to my browser to check out the grid, and it looks a little glitchy. So I open up dev tools to look at the css, and to my horror I see over 16000 characters of CSS....

Did I do something wrong? Do Compass seriously expect people to use something as bloated as this?
If you have a more succinct css-only solution for grid backgrounds, I'm sure we would be happy to use that instead. In the meantime, this mixin was only meant to be used as a development tool, so the answer to your question is mostly: No.
We don't expect you to use this in production. We expect you to turn it on for 5 minutes of grid debugging, then turn it back off. We also expect you to change your settings so that they give the output you want. Don't need legacy webkit gradients? Turn them off.
I'm not sure what magic you expected, but 24-column striped css gradients aren't succinct. You requested that, and Compass made it happen. There will never be any output that you don't request explicitly. But CSS is a mess, and simple gradients have to be repeated 5 times if you want full browser support. That's why Compass exists: You don't have to write or maintain those 16000 chars by hand, and you can change them with simple settings.

Printing tchar array as unicode string rust winapi
I'm using the winapi to grab a list of the current processes running on the system, here's my code:
use winapi::um::tlhelp32::{Process32Next, Process32First, CreateToolhelp32Snapshot, TH32CS_SNAPPROCESS, PROCESSENTRY32};
use winapi::um::winnt::HANDLE;
use winapi::um::handleapi::CloseHandle;
use std::mem::size_of;
...
fn get_processes() {
let h_process_snap: HANDLE;
// really, rust?
let mut pe32 = &mut PROCESSENTRY32{
dwSize: 0,
cntUsage: 0,
th32ProcessID: 0,
th32DefaultHeapID: 0,
th32ModuleID: 0,
cntThreads: 0,
th32ParentProcessID: 0,
pcPriClassBase: 0,
dwFlags: 0,
szExeFile: [0; 260],
};
unsafe {
h_process_snap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
}
pe32.dwSize = size_of::<PROCESSENTRY32>() as u32;
unsafe {
if Process32First(h_process_snap, pe32) == 0 {

println!("can't get a process snapshot");
// TODO: return
}
while Process32Next(h_process_snap, pe32) != 0 {
println!("{:?}", pe32.szExeFile);
}
}
}
...
Now I'm trying to print the actual name of the process, in C++, this can be done using cout or wcout.
When I use println!("{:?}", pe32.szExeFile);, this is what I get:
[115, 117, 112, 101, 114, 102, 52, 45, 114, 117, 115, 116, 46, 101, 120, 101, 0, 116, 46, 101, 120, 101, 0, 98, 108, 101, 83, 104, 101, 108, 108, 46, 69, 120, 112, 101, 114, 105, 101, 110, 99, 101, 115, 46, 84, 101, 120, 116, 73, 110, 112, 117, 116, 46, 73, 110, 112, 117, 116, 65, 112, 112, 46, 101, 120, 101, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
I don't really understand how to work with this, how can I print the pe32.szExeFile as a Unicode string in rust?
see also: https://docs.rs/winapi/0.3.6/winapi/um/tlhelp32/struct.PROCESSENTRY32.html
Thanks to #IInspectable, I used the explicit Unicode versions, e.g. Process32FirstW, and from_wide to print the values in readable format:
let os_string = OsString::from_wide(&pe32.szExeFile[..]);
// ExeFile names have a lot of trailing 0's, remove them...
let exe_files: String = os_string.into_string().unwrap().replace("\u{0}", "");
println!("{:?}", exe_files);
How to draw a star shape in ProcessingJS
Here is my current project code: size(500,500); background(255, 255, 255); fill(250,0,0); ellipse(150, 230, 100, 200); fill(10,0,0); ellipse(180, 233, 30, 30); fill(10,0,0); ellipse(120, 233, 30, 30); fill(250,250,250); ellipse(120,233,10,20); fill(250,250,250); ellipse(180,233,10,20); arc(150, 280, 60, 90, 0, PI/1); fill(250,0,0); rect(100,330,100,100); fill(10,10,10); rect(50,330,50,50); fill(10,10,10); rect(200,330,50,50); fill(250,0,0); rect(90,430,50,100); fill(250,0,0); rect(160,430,50,100); fill(10,0,0); triangle(60, 300, 101, 10, 50, 450); Could someone please provide code on how to draw a basic 5 pointed star beside the deadpool character? (within the sized 500,500 dimensions)
See the processing documentation of PShapes where there is a very simple implementation of a star shape in the Custom PShapes section.
See the p5.js example which is very similar.
The code can be used in processing.js, too. You have to change createCanvas(500,500) to size(500,500) and push() respectively pop() to pushMatrix() respectively popMatrix():
function setup() {
createCanvas(500,500);
}
function draw() {
background(255, 255, 255);
// star
push();
translate(280, 290); // center of the star
fill(102);
beginShape();
vertex(0, -50);
vertex(14, -20);
vertex(47, -15);
vertex(23, 7);
vertex(29, 40);
vertex(0, 25);
vertex(-29, 40);
vertex(-23, 7);
vertex(-47, -15);
vertex(-14, -20);
endShape(CLOSE);
translate(100, 100);
pop();
// character
fill(250,0,0);
ellipse(150, 230, 100, 200);
fill(10,0,0);
ellipse(180, 233, 30, 30);
fill(10,0,0);
ellipse(120, 233, 30, 30);
fill(250,250,250);
ellipse(120,233,10,20);
fill(250,250,250);
ellipse(180,233,10,20);
arc(150, 280, 60, 90, 0, PI/1);
fill(250,0,0);
rect(100,330,100,100);
fill(10,10,10);
rect(50,330,50,50);
fill(10,10,10);
rect(200,330,50,50);
fill(250,0,0);
rect(90,430,50,100);
fill(250,0,0);
rect(160,430,50,100);
fill(10,0,0);
triangle(60, 300, 101, 10, 50, 450);

How to create list of vars in loop?
I have a main colour #abc
and we can create colour with darken with percentage
how can i create list of darken colours with a loop?
#mixin create-color($main) {
create some vars
}
#include create-color(blue);
i will get
$c-green-1: green
$c-green-2: (green-lighten 10%)
$c-green-3: (green-lighten 20%)
This will accomplish what you're after:
#mixin alphaColor($name,$color) {
#for $i from 1 through 10 {
.c-#{$name}-#{$i} {
color: rgba($color,$i/10);
}
}
}
#include alphaColor("blue",blue);
#include alphaColor("red",#ed1414);
#include alphaColor("absurd",rgb(20,237,20));
This is a mixin that will take a color (named, hex, rgb), and loop thru it creating named (you give it an initial name) color declarations in RGBA with alpha from .1 - 1 incrementing by .1.
Output above would be:
.c-blue-1 { color: rgba(0, 0, 255, 0.1); }
.c-blue-2 { color: rgba(0, 0, 255, 0.2); }
.c-blue-3 { color: rgba(0, 0, 255, 0.3); }
.c-blue-4 { color: rgba(0, 0, 255, 0.4); }
.c-blue-5 { color: rgba(0, 0, 255, 0.5); }
.c-blue-6 { color: rgba(0, 0, 255, 0.6); }
.c-blue-7 { color: rgba(0, 0, 255, 0.7); }
.c-blue-8 { color: rgba(0, 0, 255, 0.8); }
.c-blue-9 { color: rgba(0, 0, 255, 0.9); }
.c-blue-10 { color: blue; }
.c-red-1 { color: rgba(237, 20, 20, 0.1); }
.c-red-2 { color: rgba(237, 20, 20, 0.2); }
.c-red-3 { color: rgba(237, 20, 20, 0.3); }
.c-red-4 { color: rgba(237, 20, 20, 0.4); }
.c-red-5 { color: rgba(237, 20, 20, 0.5); }
.c-red-6 { color: rgba(237, 20, 20, 0.6); }
.c-red-7 { color: rgba(237, 20, 20, 0.7); }
.c-red-8 { color: rgba(237, 20, 20, 0.8); }
.c-red-9 { color: rgba(237, 20, 20, 0.9); }
.c-red-10 { color: #ed1414; }
.c-absurd-1 { color: rgba(20, 237, 20, 0.1); }
.c-absurd-2 { color: rgba(20, 237, 20, 0.2); }
.c-absurd-3 { color: rgba(20, 237, 20, 0.3); }
.c-absurd-4 { color: rgba(20, 237, 20, 0.4); }
.c-absurd-5 { color: rgba(20, 237, 20, 0.5); }
.c-absurd-6 { color: rgba(20, 237, 20, 0.6); }
.c-absurd-7 { color: rgba(20, 237, 20, 0.7); }
.c-absurd-8 { color: rgba(20, 237, 20, 0.8); }
.c-absurd-9 { color: rgba(20, 237, 20, 0.9); }
.c-absurd-10 { color: #14ed14; }

Obtain sub-cv::Mat from a given image such that
I have a processed an image that returns a Mat say: [ [ 0, 0, 255, 255, 255, 0, 0, 0], [ 0, 0, 0, 255, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 255, 255, 0], [ 0, 0, 0, 0, 0, 255, 255, 0], [ 0, 0, 0, 0, 0, 0, 0, 0] ] are there any segmentation functions that can help me isolate individually ? if not so what would be the best approach ? i.e. say if i do mysegment(Mat a,0) should return [ [ 0, 0, 255, 255, 255, 0, 0, 0], [ 0, 0, 0, 255, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0] ] then mysegment(Mat a,1) will return [ [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 0, 0, 0], [ 0, 0, 0, 0, 0, 255, 255, 0], [ 0, 0, 0, 0, 0, 255, 255, 0], [ 0, 0, 0, 0, 0, 0, 0, 0] ] I consider continuous 255 pixels to be a block. Now I want to iterate over or process these blocks ... since more than one block can be formed in a matrix.

3D skew transformation matrix along one coordinate axis
Is there a way to calculate the skew transformation matrix along one coordinate axis, given the skew angle, as follows
This should work for the most part for skewing an object with a transformation matrix, in particular using glMultMatrix(matrix)

tan(a), 0, 1, 0,

};
matrix3[] = {
1, tan(a), 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
