I was looking to include a responsive card template into my project and used one of the templates from CodePen to do this. However, when I copied the code from CodePen to my own platform, The card would not expand when I click on "click on expand" like it is unresponsive. But over here, the code runs fine, but not on the IDE I am using.
Where I got the whole code from initially: https://codepen.io/ryanparag/pen/EOBdOK
The HTML/CSS of the card:

QUESTION
I run some benchmarks through JMH
Supposing I have three benchmarks listed in one Java File
...ANSWER
Answered 2020-Dec-02 at 09:37Each benchmark is executed in its own JVM (unless explicitly set to behave otherwise), so cross benchmark pollution should not happen. What can happen, and is quite common, is the thermal throttling of your CPU. If you are benchmarking in an environment where you have no control over CPU frequency the typical behaviour would be for the first benchmark to push CPU frequency up, and later benchmarks to get throttled. You can control for this variable in Linux environments by switching to a user controlled power governor and setting a fixed frequency for your CPU.
QUESTION
I'm trying to setup an orthographic camera in C++ and I have some problems getting the rotation correctly.
When I try to rotate the camera around the z axis by 45 degrees, everything works as expected (model is defined from -0.5f to 0.5f).
However, when trying to rotate around x axis, the angle gets really amplified (i.e. rotation around 1 radian makes it almost disappear).
Here is the related code:
...ANSWER
Answered 2020-Oct-18 at 19:23When you rotate a round the x or y axis, then the objects is clipped by the near and far plane of the Orthographic projection. By default near is -1.0 and far is 1.0. Increase the distance to the near and far plane (see glm::ortho
). For instance:
glm::mat4 projection = glm::ortho(0.0f, 800.0f, 0.0f, 600.0f);
QUESTION
Say I have 2 white images (RGB 800x600 image) that is 'dirty' at some unknown positions, I want to create a final combined image that has all the dirty parts of both images.
Just adding the images together reduces the 'dirtyness' of each blob, since I half the pixel values and then add them (to stay in the 0->255 rgb range), this is amplified when you have more than 2 images.
What I want to do is create a mask for all relatively white pixels in the 3 channel image, I've seen that if all RGB values are within 10-15 of each other, a pixel is relatively white. How would I create this mask using numpy?
Pseudo code for what I want to do:
...ANSWER
Answered 2020-Sep-17 at 13:05What you asked for is having the pixels in which the distance between colors is under 10.
Here it is, translated to numpy.
QUESTION
I'm experiencing a strange issue on MS Edge. I want to animate a door (a div tag ) around the Y axis with the css rotateY() function, combined with perspective properties. The issue is that interpolate angle from a positive value to a negative value (50deg => -100deg) produces a glitch near zero.
Here is the simplified code : https://codepen.io/stephanemill/pen/LYGowqo - Microsoft Edge 44.18362.449.0
...ANSWER
Answered 2020-Jul-30 at 03:12I can reproduce the issue in Edge Legacy. The door looks like jerking once when transforming. I thinks that's due to different rendering engines used in different browsers.
To solve this issue, you can use CSS transform perspective() function instead of CSS perspective property. The sample code is like below:
QUESTION
I am currently using the babel compiler to compile my React component libraries. I made this decision based on the fact that Create React App also uses the babel compiler. However, I am now finding that using babel to create libraries is more complicated. You need to introduce the TypeScript compiler anyway to generate type definitions. Thus I need to maintain two sets of configurations, babel and tsconfig. This complexity gets further amplified by the fact that I have multiple such libraries in a monorepo.
So my question is:
- Is there any good reason to use the Babel TypeScript compiler to compile React libraries (vs tsc)?
- Am I going to loose any features if I get rid of Babel completely and rely only on tsc?
ANSWER
Answered 2020-Jul-26 at 05:35After a lot of research, it was clear to me that when creating a TypeScript library from scratch, it does not make sense to use the Babel compiler. Babel does not do any type checking of TS files. For that I have to run the TypeScript compiler anyway. Hence it is better to use the TypeScript compiler from the get go. For create-react-app, Babel was a better choice because they were. already using it for ES6 builds.
Furthermore, I picked up a CLI/template for creating my library. It's called TXDX. It really makes the job of creating a TS library very easy.
QUESTION
TL;DR
My query has three temp tables due to the many mitigating factors described in the below post. I do not know of a way to combine the temp tables into a single temp table in order to pass information between two case statements. Nor do I have a way to pass the information between the case statements as a SET @variable = CASE
raises the "Multi-part identifier could not be bound" error. So I need a way to refactor or alter my query to allow information to be passed from one Case statement to the other.
I have a query with three temp tables running on SQL Server 2012.

it ends with a CTE

QUESTION
I have two related datasets, with one of them that can be slightly below 0.
I am trying to calculate the 'linear' percent difference between the two.
I have written some example code: perc[1] is the proper percentage method, however in the last two example cases, the percentage differences are not 'linear' for both sides (ie -87 compared to 700)- I need them to be equal or have some linearity in their calculation, whereas the last three methods are linear I guess. I like perc[3] as it is just the absolute difference and amplified, but kind of unitless. Maybe [4] or [5] is the most accurate for this use case, using the mean of the two as the denominator?
...ANSWER
Answered 2020-Mar-27 at 19:02Referencing this Wikipedia article, the relative percentage is, in general, of the form
|x - y| / |f(x, y)|
The absolute value in |x - y| can be removed if you have a reference point, so as to get negative percentages. If that doesn't make sense to you, you should keep it.
The function |f(x,y)| is what is commonly called the scaling factor. You can choose between many options here, and it depends on the application.
You can take just f(x, y) = y, as you did in (1). This is usually done when comparing experimental and theoretical values, say, after measuring in some experiment; or when measuring the change with respect to a past state. But note that it needs a reference point (the theoretical value, or the value before the change was done) and it won't have the "linearity" property you are looking for, since your scaling factors change when swapping x and y (1/2 vs 1 if we use 1 and 2). This is because, for a value of 2, suddenly changing to 10 means a 400% increase, but a 10 becoming a 2 is a 80% decrease.
So you need some function f that doesn't change on swapping the parameters. This is known in mathematics as a symmetric function. Many examples are shown in the article referenced before. I suggest (|x| + |y|)/2, but try out the others to see what makes more sense.
QUESTION
Im currently doing distance calculations between coordinates and have been getting slightly different results depending on the language used.
Part of the calulation is taking calculating the cosine
of a given radian
. I get the following results
ANSWER
Answered 2019-Oct-16 at 12:11Generally, the representation of floating point numbers is defined by the standard IEEE 754 and my assumption is that this standard is implemented by all (major) programming languages.
Precision and rounding are known issues and may sometimes lead to unexpected results.
Aspects that may have an influence on the result of a calculation depending on the programming language or used math library:
- different calculation methods (in your case: the cosine function might be implemented by numerical approximation with different approaches)
- different rounding strategies during calculation or for the final output
