QUESTION
i read the (go)mem info from runtime.MemStats, but cant found rss value, i use m.HeapSys-m.HeapReleased, but found the value is very not like rss ,also i dump the Rss by other tool(github.com/shirou/gopsutil/process), i want to know how to get the rss by memstats, and why m.HeapSys-m.HeapReleased, and m.Sys not equal the rss, so different the value ?
...ANSWER
Answered 2022-Feb-23 at 16:04[H]ow to get golang rss from runtime.MemStats [?]
You cannot. runtime.Memstats doesn't provide that information.
why m.HeapSys-m.HeapReleased, and m.Sys not equal the rss [?]
Because RSS is a completely different metric.
QUESTION
I am trying to reduce code duplication by writing functions to generate user interfaces.
However, it seems I am unable to create multiple selectizeInput
elements with the arguments selected
and selectize
both set to FALSE
. This is important because I need some elements initially set to NULL
which can only be done this way.
Example that fails
...ANSWER
Answered 2022-Jan-01 at 21:14For now, I have switched to selectInput
since this is not a performance stringent application. This seems to work as required.
QUESTION
We are facing issues with varnish Max Threads hit & backend and session connections spikes. We are not sure about the cause, but what we have observed is it happens when the origin servers have high response times and eventually return uncacheable (502) responses.
Varnish usage :
We've configured varnish behind nginx proxy, so the incoming requests first hit nginx and then is consistently balanced to n varnish. Varnish, in case of miss, call the origin nginx host, here example.com.
In our case, we only cache HTTP GET requests and all of them have JSON payload in response, size ranging from 0.001 MB to 2 MB.
Example request :
HTTP GET : http://test.com/test/abc?arg1=val1&arg2=val2
Expected xkey : test/abc
Response : Json payload
Approx QPS : 60-80 HTTP GET Requests
Avg obj ttl : 2d
Avg obj grace : 1d
Attaching the vcl file, statistics and varnish run command for debugging purpose.

Varnish and VCL Configuration :
Varnish version : Linux,5.4.0,x86_64,varnish-6.5.1

Here's a varnishstat
command that displays realtime thread consumption and potential thread limits:

I would like to plot for example a square (or maybe more generally speaking a n-gon).
I know that I can plot "functions" that form a shape, like a circle:

...ANSWER
Answered 2021-Jun-23 at 02:36c.Data
writes the given bytes verbatim, setting the Content-Type
to application/json
, so the receiver knows how to interpret data.
c.JSON
first converts the input data into JSON. In your case the input data is a string, so it is marshaled to convert to a JSON string.

So I currently have a function that will take in a string APIKey
to check it against my MongoDB collection. If nothing is found (not authenticated), it returns false - if a user is found, it returns true. My problem, however, is I'm unsure how to integrate this with a Gin POST route. Here is my code:

QUESTION
I am interested in the Hyperbolic Tessellations such as those generated by @TilingBot. To narrow it down a bit more, I would like to be able to construct some of the Uniform Tilings on the Hyperbolic Plane, such as this:
The closest answer I have found comes from Math SE and recommends these 3 resources:
- Ajit Datar's master's thesis
- David Joyce's Hyperbolic Tessellations applet
- And David Joyce's corresponding Java source code.
Here I have translated the Java to JavaScript (and preserved the comments), as well as attempted to draw the center shape:

Answered 2020-Sep-28 at 23:05I would recommend you do a stroke instead of fill, that way you see what that polygon is giving you.
Run the code below so you can see the difference...
Now, comparing that result with your image it looks nothing like what you want
QUESTION
Edit: So I found a page related to rasterizing a trapezoid https://cse.taylor.edu/~btoll/s99/424/res/ucdavis/GraphicsNotes/Rasterizing-Polygons/Rasterizing-Polygons.html but am still trying to figure out if I can just do the edges
I am trying to generate points for the corners of an arbitrary N-gon. Where N is a non-zero positive integer. But I am trying to do so efficiently without the need of division and trig. I am thinking that there is probably some of sort of Bresenham's type algorithm for this but I cannot seem to find anything.
The only thing I can find on stackoverflow is this but the internal angle increments are found by using 2*π/N: How to draw a n sided regular polygon in cartesian coordinates?
Here was the algorithm from that page in C
...ANSWER
Answered 2020-Jul-19 at 04:42There's no solution which avoids calling sin
and cos
, aside from precomputing them for all useful values of N
. However, you only need to do the computation once, regardless of N
. (Provided you know where the centre of the polygon is. You might need a second computation to figure out the coordinates of the centre.) Every vertex can be computed from the previous vertex using the same rotation matrix.
The lookup table of precomputed values is not an unreasonable solution, since at some sufficiently large value of N
the polygon becomes indistinguishable from a circle. So you probably only need a lookup table of a few hundred values.
