kandi X-RAY | Spreads Summary
The name Spreads stands for Series and Panels for Real-time and Exploratory Analysis of Data Streams. Spreads is an ultra-fast library for complex event processing and time series manipulation. It could process tens of millions items per second per thread - historical and real-time data in the same fashion, which allows to build and test analytical systems on historical data and use the same code for processing real-time data. Spreads is a library, not a framework, and could be plugged into existing code bases and used immediately. Even though the primary domain is financial data, Spreads was designed as a generic complex event processing library, with a performance requirement that it must be suitable for ticks and full order log processing. This is probably the largest data stream that cannot be meaningfully sharded: financial instruments are all directly or indirectly correlated and we need to monitor markets as a whole while Google/Facebook and similar user event streams could be processed independently.

Other people are having same problems where everything breaks down after the update, see the recent issues opened here. My suggestion is to downgrade the react types until they release a hotfix for this. See also this issue
QUESTION
For practice I've implemented the qoi specification in rust. In it there is a small hash function to store recently used pixels:
index_position = (r * 3 + g * 5 + b * 7 + a * 11) % 64
where r, g, b, and a are the red, green, blue and alpha channels respectively.
I assume this works as a hash because it creates a unique prime factorization for the numbers with the mod to limit the number of bytes. Anyways I implemented it naively in my code.
While looking at other implementations I came across this bit hack to optimize the hash calculation:
...ANSWER
Answered 2022-Apr-08 at 02:28If you think about the way the math works, you want this flipped order, because it means all the results from each of the "logical" multiplications cluster in the same byte. The highest byte in the first value multiplied by the lowest byte in the second produces a result in the highest byte. The lowest byte in the first value's product with the highest byte in the second value produces a result in the same highest byte, and the same goes for the intermediate bytes.
Yes, the 0x78...
and 0x03...
are also multiplied by each other, but they overflow way past the top of the value and are lost. Having the order "backwards" means the result of the multiplications we care about all ends up summed in the uppermost byte (the total shift of the results we want is always 56 bits, because the 56th bit offset value is multiplied by the 0th, the 40th by the 16th, the 16th by the 40th, and the 0th by the 56th), with the rest of the multiplications we don't want having their results either overflow (and being lost) or appearing in lower bytes (which we ignore). If you flipped the bytes in the second value, the 0x78 * 0x0B
(alpha value & multiplier) component would be lost to overflow, while the 0x12 * 0x03
(red value & multiplier) component wouldn't reach the target byte (every component we cared about would end up somewhat that wasn't the uppermost byte).
For a possibly more intuitive example, imagine doing the same work, but where all the bytes of one input except a single component are zero. If you multiply:

QUESTION
I have multiply taps in one sheet A
, each tap has 5000+ rows, some rows have the same content and want to find specific rows, while entering content and copy those rows which are matching to a different sheet B
and keep the formatting etc from sheet A.
Example:
I need to make a shipping/order list
I have 2 sheets Sheet A
is full of information (my stockload), multiply tabs with a lot of rows in each tab. in Sheet B
(new URL) I want to filter the information.
Lets say, I have 5000 articles spread in 5 tabs on Sheet A
, someone is ordering 20 articles, so I just want to scan the EAN or any other code on that article to Sheet B
, and all rows with that data, will be imported. Now I have a brand new list with only the 20 articles, which I can share to the client.
I have tried with script:

QUESTION
I'm not sure how to even ask about this; hopefully this explanation is clear enough.
Using a VBA recorded macro, with the relative selection on, I have a formula that uses the countif($C$656:C656,[@Column1])
(which is actually the cell directly below the Table Header, Column1)
The problem I'm facing is the formula doesn't translate as the variable locations because I don't know how to use relative code to actually tell vba to search all the way up the Table column until you reach the cell directly below the header. It must be relative because the table is not always created on row 655 and has varying numbers of rows within the table itself so I can't tell VBA R[1]C[1]:R[367]c[1]
for example.
Below is the formula entered in the cell itself (B656).
...ANSWER
Answered 2022-Feb-15 at 16:08Don't use cell references within tables and much of your problem goes away.
Assuming your table is named "Table1", try inserting a new column titled DataRowsAbove with a formula of =ROW()-ROW(Tables[#Headers]-1
Then insert another column titled Column1Repeated with a formula of =IF([@DataRowsAbove]=0,0,COUNTIF(OFFSET(Table1[#Headers][Column1],1,0,[@DataRowsAbove],1),[@Column1])
The offset is the secret sauce, here. It gives you a range of every Column1 value above the current line without any cell address references.
Then your Column2 formula can be

QUESTION
I am trying to render a table on shinyapps.io, but it is populating with all NA's. I am scraping NCAA basketball spreads from https://www.vegasinsider.com/college-basketball/odds/las-vegas/. Locally, the table renders fine. But on shinyapps.io, all the numeric spreads display as NA's. It only displays correctly on shinyapps.io if all the spread values are characters. But then I cannot perform any math operations. As soon as the BetMGM, Caesers, FanDuel columns are numeric, they display with NA. I'll provide some code and data to help recreate the issue. There was a lot of data cleaning steps that I will skip for the sake of brevity.
@akrun here is the code to scrape the table. I do this and then some regex to split apart the game_info into components.
...ANSWER
Answered 2021-Dec-24 at 16:58It seems that the spread_table
after scraping may be post-processed in a way that couldn't convert the extracted substring into numeric
class - i.e. when we do as.numeric
, if there is any character, it may convert to NA
.
In the below code, select
the columns of interest after scraping, then extract
the substring from the 'game_info' column to split into
'date', 'time', 'away_team_name' and 'home_team_name' based on a regex pattern matching and capturing ((...)
) those groups that meet the criteria. (^(\\S+)
) - captures the first group as one or more non white spaces characters from the start (^
) of the string, followed by one or more white space (\\s+
), then capture characters that are not newline character (([^\n]+)
) followed by any character that is not letter ([^A-Za-z]+
), capture third groups as one or more characters not the newline followed by again the characters not a letter and capture the rest of the characters ((.*)
). Then loop across
the 'BetMGM' to 'FanDuel', extract the substring characters not having u
or -
and is followed by a space ((?=\\s)
), replace the substring fraction with + 0.5
(as there was only a single fraction), loop over the string and eval
utate the string
QUESTION
I am creating an InDesign plugin where one of the features is to draw shapes on a given page.
I get a drawing from the backend with the page number on which it should be drawn.
For this, I do :
app.activeDocument.pages[index]
to get the page I want.
Unfortunately, I realized that this technique only works when the pages are not facing each other like this :
When the pages are facing each other like this :
, the shapes on page 3 will be drawn on page 2 instead of on page 3.
Here, the drawings are on the right page :
But here, the rectangle isn't on the right page :
