kandi X-RAY | fixed Summary
A fixed place numeric library designed for performance. All numbers have a fixed 7 decimal places, and the maximum permitted value is +- 99999999999, or just under 100 billion. The library is safe for concurrent use. It has built-in support for binary and json marshalling. It is ideally suited for high performance trading financial systems. All common math operations are completed with 0 allocs. Primarily developed to improve performance in go-trader. Using Fixed rather than decimal.Decimal improves the performance by over 20%, and a lot less GC activity as well. You can review these changes under the 'fixed' branch. If you review the go-trader code, you will quickly see that I use dot imports for the fixed and common packages. Since this is a "business/user" app and not systems code, this provides 2 major benefits: less verbose code, and I can easily change the implementation of Fixed without changing lots of LOC - just the import statement, and some of the wrapper methods in common.

QUESTION
I've come across an issue of trying to fade the edges of the background image of a div so that it looks like it's blending with the background image of the full site (so the background image applied to the body).
...ANSWER
Answered 2021-Jun-16 at 02:49You can use the background as gradient where the edges are rgba(0,0,0,0). This way it will smoothly blend with background. But this will not work for images. For images You will have to a div of background color and rgba(0,0,0,0) in gradient with color facing outward.
QUESTION
I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.
I can figure out how to change one area, but unsure how to implement the other areas.
What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.
What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?
...ANSWER
Answered 2021-Jun-15 at 11:48You could try having a "select" function run when you click on one of the areas. This function would "highlight" the area (border-color), and save the id of the area in a variable.
Then when you click on the color swatches another function would run that will take the value previously saved id and select the HTML element based on that.
QUESTION
A part of my form contains QGroupBox (Status Box) with 4 child QGroupBoxes arranged in a grid layout (2x2). Two bottom QGroupBoxes (Widget 1 Box and Widget 2 Box) contain widgets of fixed size (with set minimumSize and maximumSize) so they're non-resizable at all in both directions. Because of that rigid size constraints top row of QGroupBoxes (Summary Box and Helper Box) can only be resized in vertical direction.
And here comes the troublesome part. Top-left QGroupBox (Summary Box) have grid layout 5x3 while top-right (Helper Box) have vertical layout with 6 rows. If I have naive widget placement as shown on picture 1 Qt is enlarging vertical size of both labels in top row to make height of both QGroupBoxes equal (see red arrows on picture 1).
This is definitely that I don't want so I've added vertical spacer to the bottom of Summary Box and from the first glance it worked (picture 2). But only from the first glance... What you see is the minimum height of my whole form and the bottom side of spacer and last QCheckBox in the Helper Box seems to be aligned.
If I'm expanding my form vertically this spacer grows a bit and that causes the increase of height of both top QGroupBoxes. As a result spacing between QCheckBoxes increases too and we can also see that top and bottom spacing are unequal for the top-right box (see red arrows on picture 3).
I've tried to play with sizeType for my vertical spacer. If I set it to Minimum or MinimumExpanding then the spacer doesn't grow on resize (and doesn't shrink, too) but it appears to be expanded to the size as on picture 3 (corrupting spacings between QCheckBoxes too). If I set it to Maximum, Preferred or Expanding then I observe the same behavior as described above for picture 3.
What is the proper way to achieve alignment for two QGroupBoxes in a row of grid without affecting spacing between elements (e. g. in that case make vertical spacer to fit only single row of grid layout and never expand/shrink)?
ANSWER
Answered 2021-Jun-15 at 17:18Items will be aligned if both QGroupBoxes have same count of children and each row have at least one child with Expanding vertical policy. Instead of spacer use QWidget
I removed unrelated widgets and reduces number of rows to 4 for demonstration purposes (less xml).

QUESTION
I have some JSON data in Google Sheets that I wish to parse for the data after a keyword, eg:
"splashtopname":"DESKTOP-XXYYZZ"
This is in the middle of the JSON data which is delimited by commas eg:
"cpuidentifier":"Intel64 Family 6 Model 92 Stepping 9","splashtopname":"DESKTOP-XXYYZZ","splashtopversion":"3.4.6.2",
What I want to do is extract DESKTOP-XXYYZZ only from this (however this string length is variable and not fixed, nor does it always begin DESKTOP). I am stumped as to the formula to get this output, so any help would be greatly appreciated.
Thanks in advance!
...ANSWER
Answered 2021-Jun-15 at 16:31Using REGEXEXTRACT should achieve your wanted data.
=REGEXEXTRACT(A1, """splashtopname"":""([^""]*)""")
Simply extract from pattern "splashtopname":"" via regex.
QUESTION
I expect that this code prints "0" since the starting size of the array is 0, but what it does is printing "1". Can someone explain me why, using Arrays.asList on an empty collection alter the size of the resulting collection? I know that "asList" gives back a fixed-size array but still I cannot imagine what's the reason behind that.
...ANSWER
Answered 2021-Jun-15 at 16:26Because you've made a list of byte arrays. Not a list of bytes.
In other words, your list contains 1 item: An empty byte array.
You can't easily turn a byte[] into a List. There are slightly less trivial ways to do it (just do the obvious thing: Write a for loop), but note that a List is about 10x more wasteful than a byte[]. Generally, you don't 'want' a List, unless you are really very sure you do. Just about every byte-stream related API takes a byte[], In/OutputStream, or ByteBuffer, and rarely if ever a List, for example.
EDIT: To be clear, if the component type is not a primitive, then lists are just as efficient as arrays are, in practice more efficient (because it is cleaner code, and that is the only feasible road to a non-trivially-sized project that performs well). It's just collections-of-primitives that are, and it's the worst, by far, when we're talking about byte[].

Answered 2021-Jun-15 at 13:53There are all manner of clustering algorithms and many are implemented in scikit-learn.cluster. They are well documented and the docs have nice examples, but the various algorithms have trade-offs which can take a while to figure out. For example if you have a general idea about how spaced the clusters are (reflected in the epsilon parameter) you can get good results with DBSCAN:
