QUESTION
I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as
...ANSWER
Answered 2021-Jun-15 at 18:32Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.
Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():
QUESTION
In my project, I've hand-rolled a tiny dialog box that can be used to pick a key and/or mouse combination, "S" or "CTRL-SHIFT-C" or something. I had it working fine in Linux and Windows, but when I went to check it on the Mac, the dialog box would only respond to mouse events.
I boiled it down to a ~30-line minimal example, which actually made it be broken in the same way, mouse events but no keyboard, on Linux. On Windows my minimal code works as expected.
I've looked at the demo code, and I feel like I'm doing pretty precisely the things they're doing, so I'm stumped, most especially by the simple code being broken on Linux. Is there some magic or secret to making key events work reliably and cross-platform?
...ANSWER
Answered 2021-Jun-15 at 03:35I just ran this on OSX 11.4. Works fine with mouse and key events. The imporant part on OSX (and I suspect Linux as it is more similar to OSX than Windows) is that the parent panel is getting the focus and the events. Also, StaticText can't get focus.
Here's the working code:

import yfinance as yf
msft = yf.Ticker('MSFT')
data = msft.history(period='6mo')
import mplfinance as mpf
data['30 Day MA'] = data['Close'].rolling(window=20).mean()
data['30 Day STD'] = data['Close'].rolling(window=20).std()
data['Upper Band'] = data['30 Day MA'] + (data['30 Day STD'] * 2)
data['Lower Band'] = data['30 Day MA'] - (data['30 Day STD'] * 2)
apdict = (
mpf.make_addplot(data['Upper Band'])
, mpf.make_addplot(data['Lower Band'])
)
mpf.plot(data, volume=True, addplot=apdict)

Answered 2021-Jun-15 at 01:49- As per Adding plots to the basic mplfinance plot(), section Plotting multiple additional data sets
- Aside from the example below, for two columns from a dataframe, the documentation shows a number of ways to configure an appropriate object for the
addplotparameter. apdict = [mpf.make_addplot(data['Upper Band']), mpf.make_addplot(data['Lower Band'])]works as well. Note it's alist, not atuple.

QUESTION
Hello and thank you for reading this.
First off, I have to say that I can't use JavaScript. I am not aloud to any code that needs 'upkeep' because we run hundreds of sites for hundreds of clients in-house clients. Any code that needs maintenance is highly discouraged. I've tried to push back and it's not working. I don't have the power.
With that said, I have a client that would like to have icons to represent topics and when you roll over the icon, there is an overlay over said icon with the text saying what the topic is.
For example, if there is the topic 'Fruit' there would be a photo representation of a fruit (say, a banana). When the mouse rolls over the banana pic, an overlay would appear with the word fruit in the middle.
This isn't about the overlay or the icon.
What I would like to know is if I can read read the topic name in and have that displayed in the :after pseudo element.
In pretend code, this is what I'm tryin to do:
...ANSWER
Answered 2021-Jun-15 at 00:43You may set up the pseudo class with :hover::after selector, with the content of attr(topic)
QUESTION
I have this module I made for a discord.py bot (not a COG though). It clearly has the function "help_command" defined but whenever I try to run it it gives me the above error. I couldn't wrap my head around it so I thought it might worth it to ask the community.
discord_main.py
ANSWER
Answered 2021-Jun-14 at 17:28I think the problem is that you are importing from discord_main in embed_storage and vice-versa.
You need to resolve this somehow or, if there is no other way, you could move the import into the function definition, e.g. in embed_storage.py:
QUESTION
I have a data frame that is indexed from 1 to 100000 and I want to calculate the slope for every 12 steps. Is there any rolling window for that?
I did the following, but it is not working. The 'slope' column is created, but all of the values as NaN.
ANSWER
Answered 2021-Jun-14 at 15:14- It's not necessary to use
.groupbybecause there is only 1 record per day. - Don't use
.reset_index(0, drop=True)because this is dropping the date index. When you drop the index from the calculation, it no longer matches the index ofdf, so the data is added asNaN.df['Close'].rolling(window=days_back, min_periods=days_back).apply(get_slope, raw=True)creates apandas.Series. When assigning apandas.Seriesto apandas.DataFrameas a new column, the indices must match.
QUESTION
CREATE OR REPLACE FUNCTION PPP ()
RETURNS cursor
F1: BEGIN ATOMIC
declare c1 cursor ;
set c1 = CURSOR FOR select * from aaa ; {get error here}
RETURN c1 ;
END
ANSWER
Answered 2021-Jun-14 at 07:15You get this error because your syntax is not valid.
One of the many restrictions on inline SQL blocks (that is, any compound block that starts withBEGIN ATOMIC ), is that:
"Cursors and condition handlers are not supported in inline SQL PL and therefore neither is the RESIGNAL statement."
See docs.
To get your code to compile , the function should not be inlined, but instead be a compiled block, replace BEGIN ATOMIC by BEGIN.
Compilation is just the first step, you will also need to get the function to execute correctly - other changes may be needed.

QUESTION
I am new to vue js and front end development. How can I direct the console errors and API errors from front end application that is running on user's browser to cloud watch logs.
I know that in Java backend development, we can use log4j to log the errors to a rolling log file and wire those logs to cloudwatch log groups (so I can monitor cloudwatch logs for any potential errors or warnings). How can I have similar functionality for logging console and API errors from front end vue js application to cloud watch logs
...ANSWER
Answered 2021-Apr-22 at 01:19There really isn't a great way to do this from a security standpoint. You'd have to expose your cloudwatch log stream to the world essentially.
You can use npm packages like winston-cloudwatch for this fairly easily, but you have to more or less "hardcode" your credentials since a frontend/vue app runs in the users browser. They'll always be able to see the credentials you're sending along which makes them meaningless.
With that being said, there really isn't any risk of someone doing anything malicious besides sending dirty messages to your logs.
