How to multiply every row in dataframe by value from csv file

Asked 2021-Jun-15 at 21:54

Here's my csv file CSV

I'm trying to take the mean of columns "Angle Min" and "Angle Max" and then multiply every row in the resulting dataframe with the "Angle Conversion Factor" in cell D8. Likewise I want to do the same with "Torque Min" and "Torque Max" (get the mean and then multiply the resulting dataframe by the "Torque Conversion Factor" in Cell E8).

Here's my code so far:

Your AngleConcFactor and TorqueConvFactor remain as 1x1 DataFrames in your code. Just a slight cleanup of your function might give you what you need:

Crash on a protocol witness related issue

In my iOS app "Progression" there is rarely a crash (1 crash in ~1000+ Sessions) I am currently not able to fix. The message is

ANSWER

Answered 2021-Jun-15 at 13:26

While editing my initial question to add more context as Jay proposed I think it found the issue.

What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.

My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.

Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.

The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

What is the reset type of the reset signal of an always_latch .?

Asked 2021-Jun-15 at 06:39

I don't have much knowledge on system verilog and I have the following question.

As I know, if an edge of a reset signal has been triggered in the sensitivity list of an always block then the reset type of that reset signal is 'asynchronous' I need to know, what is the reset type of the reset signal of an always_latch?

...

ANSWER

Answered 2021-Jun-15 at 06:39

Both resets are asynchronous. You cannot have a synchronous reset in a latch because there is no clock. The always_latch construct in your example creates an implicit sensitivity list

Django does not look for any file named signal.py, etc. by default. Hence what is happening it that your signals are never registered (in fact the file you write them in is never run). The general solution to adding signals is to write them in a separate file and then import / register them in the app config's ready method.

In the app in which you write signal.py there should be a file apps.py in which there should be a class inheriting from AppConfig edit this class and add a ready method to it and import your signals there:

Qt. signal linked to slot of latest object

I am creating multiple object of type QWidget_WindowContact at runtime. When I click the Increment or decrement buttons the value in the last generated object gets updated and not the value in the same object.

I am struggling to properly link the signals and slots, so that when multiple objects of the same type are generated at runtime the signal emitted by the button coressponds to the signal in the right object.

ANSWER

Answered 2021-Jun-14 at 02:02

SIGNAL means the string representation of the function and &QAction::triggered is a function pointer. SIGNAL is the old way of doing things and slow due to string comparison at run time.

The following line of code will resolve to a connect which uses string comparison of signal and slot.

Creating a Bullish engulfing candle script

Asked 2021-Jun-14 at 01:57

Just getting started with Pine Script and coding in general. I found a couple open source scripts that was able to signal a buy when there is an engulfing bullish candle. Is there a way to code it so that there has to first be 3 bearish candles and then a bullish candle to signal the buy? Image 1 shows what I am wanting with 3 red candles then signal a buy. Image 2 shows that there was only 1 red candle and then there was a bullish candle that signaled a buy.

threeRed = close[1] < open[1] and close[2] < open[2] and close[3] < open[3]

oneRed = close[1] < open[1]

bullishEng = close > open and close > max(open[1], close[1])

buySignal1 = oneRed and bullishEng and not threeRed
buySignal3 = threeRed and bullishEng
