QUESTION
I have a concave hull (not convex) that I have the points for eg: A,B,C,D,E. I've gotten the pairs of points that make up the outer edges. [A,B],[A,E],[C,D],[B,C],[E,D]. (This is a very simplified version)
I want to get the connected points in order (CW or CCW doesn't matter) so I can use them as a contour.
But the pairs are not ordered, you can see A goes to B, then A goes to E, etc. The only solution I had was searching for each point and its next pair sequentially in a loop
Is there a way to solve this using numpy only in a vectorized manner so that its fast for a large array of edges? I know shapely exists but I have trouble installing it and I'd prefer no external dependancies
this is my code:

QUESTION
I have data in devanagari that needs some extraction to be done. This is an example of a few lines
तत् इदम् K7 <<<<K1-अर्थ>T6-सार>T6-संग्रह>T6-भूतम्>T2 K1 <T6-आविष्करणाय>T6 अनेकैः <<T6-T6>Di-न्यायम्>T6>Bs6 अपि <K1-K1>K1 त्वेन लौकिकैः गृह्यमाणम् उपलभ्य अहम् विवेकतः <T6-अर्थम्>T4 संक्षेपतः विवरणम् करिष्यामि
T4 अपि यः Bs6 धर्मः वर्णान् आश्रमान् च उद्दिश्य विहितः सः <<<Bs6-स्थान>T6-प्राप्ति>T6-हेतुः>T6 अपि सन् <T6-बुद्ध्या>T6 अनुष्ठीयमानः T6 भवति <T6-वर्जितः>T3
The alphanumerics are the tags of the text. I need to extract the binary compounds along with their tags (the alphanumerics immediately after the compound) from the line. Binary compounds are the two words hyphenated in the angular brackets.
<<T6-T6>Di-न्यायम्>T6>Bs6
The first two are both examples of binary compounds whereas the last one is not. The simplest way to identify a binary compound is to find two words hyphenated enclosed by one set of angular brackets and followed by a single tag.
So after extraction, of say the first line, I should get a list with this in it

QUESTION
I’m loving the expanded CSS support in SVG2. It’s great not having to rewrite attributes over and over. So I’ve been converting some code in a project from SVG attributes to CSS. Most of this has worked just fine.
When it comes to transforms, things can seem tricky if you are comfy with how CSS transforms work in HTML. (This is especially true for rotate() transformations, which is the focus of this question.) That’s because SVG doesn’t have the “automatic flow” that HTML does.
In other words, when you have a bunch of HTML elements, one after another, they will automatically lay themselves out according to the box model.
There is no such “automatic” or “default” layout in SVG. As a result, SVG transforms default to being calculated from the origin. (That’s 0,0 in user coordinates).
For most elements, there’s a simple solution: the awesome CSS property transform-box. In most cases, using the following CSS will allow you to transform SVG elements in pretty much the same way as HTML elements:

Answered 2021-May-22 at 18:42So you want to put an element somewhere with , and then rotate it in place?
The simplest solution I have found does include the transform attribute, but you don't need to specify the rotation point. See the following example, where the green rectangle does what you want.
In CSS, we include use elements in the transform-box rule. Then we position and rotate each element with the transform attribute (replacing x, y and CSS rotation):
QUESTION
ANSWER
Answered 2021-May-17 at 14:16Your code is missing two return statements, one on the CallNextHookEx(), and one at the end of the callback. So, the return value of the callback is indeterminate unless the input string matches your criteria. Your compiler should have warned you about the second missing return. A function with a non-void return type must exit with a return ; statement.
Try this instead:

QUESTION
Application: we are working in a sector where our product can have hundreds of different properties. And when we have to do an offer for tens products, this app could help us to reduce the number of offers by gathering products with the same configuration
How it works: user gives the properties in the entries and the application will compare them to see if some configurations are the same (Here configuration = "Config 0", or "Config 1" and so on ...).
The configurations and the given properties should be put in a dictionary-like {Config 1:[1800,1,1500,x...], Config 2:[2000,2,1600,x...], Config n:[x,y,o,x...]} The program will compare the values list of the keys and try to if some values list are the same.
Problem: I have not managed to compare the values of the dictionnary to know if there are keys with the same values
How can I solve this problem?
The button 'Launch' enables to launch of the comparison
...ANSWER
Answered 2021-May-11 at 14:03it looks like what you are comparing is a list of tkinter entry instances. What you need to do is extract the value from the entry, and then compare the values. You cannot do a comparison on an entire list, because what you are comparing is the list object itself, not the values.

QUESTION
I am adding alarms/monitoring to a logging pipeline. Specifically, I am creating CW Alarms that are triggered on 50+% disk/memory utilization for EC2 instances within an Auto Scaling Group. The ASG is created in the "workers" module directory and outputs the scaling group name for reference in alarm creation which occurs in the "cloudwatch" module directory.
I am struggling to understand a few things about creating this alarm:
- do all dimensions of a metric have to be referenced in alarm creation?
- and, if so, how do I reference InstanceID when only target group/scaling groups are defined in the TF files?
in "alarms" parent module:
...ANSWER
Answered 2021-May-08 at 02:29do all dimensions of a metric have to be referenced in alarm creation?
Yes.
and, if so, how do I reference InstanceID when only target group/scaling groups are defined in the TF files?
You can't do this (easily) from TF. Once you use ASG to manage your instances, they are out of your control, thus you can't get their IDs directly. Also you shouldn't do this, even if you could. Instances in ASG should be treated as group (thus, there is "Group" in Auto Scaling Group name), not as an individual entities.
Even if you could do this (easily), how would you manage these alarms? ASG can replace your instances at any time, leaving lots of dead alarms after a while, and new instances without any alarms.
The proper way to manage this, would be through CloudWatch Event rules, outside of your TF. You would have to detect additions and terminations of instances by your ASG. Any such action would trigger a lambda function which would add/remove alarms dynamically in response to ASG events.
