| Automate set color cell based on html color code in other column in Excel Posted: 16 Dec 2021 03:39 AM PST I have a column in excel with color codes like: #98BF64 #D9B300 #FF6347 #118DFF #D9B300 #DEEFFF #FF7F48 #000000 #00334E #B3B0AD
And I want each color code to be the fill color of the next column in my spread sheet. I am doing this by hand formatting the fill cell with each custom color code in hex option. I have a loooong list so I wonder, is there a way to automate this? |
| why number and string values are not a true condition for Rust Posted: 16 Dec 2021 03:39 AM PST As we know in some languages like javascript we can control our flow of instructions like this: // This could be something like `-2` or `9` const number = calc(); // This may be `undefined` or empty const name = getName(); if(number && name) { // do staff for truly conditions (number is bigger than `0`) }
Why in Rust-lang can't we use these conditions(always we should be explicit)? fn main() { let number = calc() let name = getName() if(name && number) {} // Error -> mismatched types }

| Using a CSV file as input for searchbar function Posted: 16 Dec 2021 03:39 AM PST Good day, I am struggling to figure out how to use a CSV file as input for a search bar function. The search bar was initially created to search within a certain list. Now I can scrap that list and that same search bar needs to search within a list of products in a CSV file. I don't know where to even begin. Here is a code I have to use to display the list of products from a CSV file, from here I do not know how to use this displayed list and have it behave like data that can be searched in the search bar created previously. '''<?php class Item { public $itemNumber; public $name; public $type; public $make; public $model; public $brand; public $description; } echo "<html><body><center><table>\n\n"; $file = fopen("input.csv", "r"); while (($data = fgetcsv($file)) !== false) { echo "<tr>"; foreach ($data as $i) { echo "<td>" . htmlspecialchars($i) . "</td>"; } echo "</tr> \n"; } fclose($file); echo "\n</table></center></body></html>";
?>''' This is the PHP code I was provided for the assignment that I need to use. |
| Adding numbers on a string with condition R Posted: 16 Dec 2021 03:39 AM PST I have the following data where e_in is exogenous giving. Ann then is an equal distribution of e_in, however, e_in can only be distributed downwards, i.e. a string (this is why 7 and 8 has ann=9 while 1 to 6 have ann=8.5) e_in<-c(13,10,4,9,14,1,11,7) ann<-c(8.5,8.5,8.5,8.5,8.5,8.5,9,9) Dat_1<-data.frame(e_in,ann) >Dat_1 e_in ann 1 13 8.5 2 10 8.5 3 4 8.5 4 9 8.5 5 14 8.5 6 1 8.5 7 11 9.0 8 7 9.0
I would now like to calculate how much e_in is available at each point down the string (shown as smn). So for 1 there is 13 e_in avabile, where 1 will take 8.5. Number 2 will then have own e_in + whatever is send downwards form 1 (here 10 + (13-8.5) = 14.5) and so on. As the following: smn<-c(13,14.5,10,10.5,16,8.5,11,9) Dat_2<-data.frame(e_in,ann,smn) >Dat_2 e_in ann smn 1 13 8.5 13.0 2 10 8.5 14.5 3 4 8.5 10.0 4 9 8.5 10.5 5 14 8.5 16.0 6 1 8.5 8.5 7 11 9.0 11.0 8 7 9.0 9.0
Is there any easy way/package for this sort of calculation (I have done it 'by hand' for this example but it becomes significantly more time consuming with bigger strings.) |

| Why does this exception about deleting shared_ptr happen? Posted: 16 Dec 2021 03:38 AM PST I'm trying to write a simple text query program in C++. In this program I exploit shared_ptr to make class QueryResult to visit class TextQuery member. At the end of the function void runQueries(ifstream &infile), it jump into the function virtual void _M_dispose() noexcept { delete _M_ptr;} in the head file shared_ptr_base.h and throw out an exception as follow. Exception has occurred. Unknown signal. Here is the function runQueries void runQueries(ifstream &infile){ TextQuery tq(infile); shared_ptr<TextQuery> sp(&tq); QueryResult qe(sp); while(true){ cout << "enter word to look for, or q to quit:"; string s; if(!(cin>>s)||s=="q") break; qe.print(cout,tq.query(s)) <<endl; } cout <<sp.use_count()<<endl; }
While in the class QueryResult , it has member variable shared_ptr sp which is initialized at constructor. I conjecture that the cause of the exception might be releasing problem of smart pointers. Could anyone tell me the actual reason? Thanks in advance. |
| Click make Argument mutex Posted: 16 Dec 2021 03:38 AM PST I'm writing a CLI using the beautiful click library the use case i want to implement is something like this: cmd <arg> <option --list> arg: required --list: optional
rationale But... the --list show only the available arg so my purpose is to make all arguments optional in this use case. I'm started from this request on the official repo, and a previous similar question very similar but it works only on Options. I've not found an elegant solution because Arguments works differently, In my real case I have a lot of arguments and options, so is not possible to reduce all Arguments into Options. |
| Problem converting epoch to datetime - python Posted: 16 Dec 2021 03:38 AM PST I have a pandas data frame showing timestamp in epoch. I need to convert it to datetime format. The code looks like this: import pandas as pd import numpy as np import datetime import time data_all = pd.ExcelFile('testData_02.xls') data = pd.read_excel(data_all, 'TestData') GPSTime = data.loc[:,'GpsUtcTime'].astype(int) # In epochs #GPSTime = pd.to_numeric(GPSTime,errors='coerce') print(type(GPSTime)) datetime_time = datetime.datetime.fromtimestamp(GPSTime).strftime('%c') Time_str = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(GPSTime))
The data type comes out as pandas.core.series.Series. I've tried converting it to int using .astype(int) and pd.to_numeric, but neither seems to work. The code returns the following error: In [8]: %run NKS_combmorc <class 'pandas.core.series.Series'> --------------------------------------------------------------------------- TypeError Traceback (most recent call last) ~\Documents\Data\NKS_combmorc\NKS_combmorc.py in <module> 35 #datetime_time = datetime.datetime.fromtimestamp(GPSTime).strftime('%c') 36 #datetime_time = dates.num2date(GPSTime, tz='UTC') ---> 37 Time_str = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(GPSTime)) 38 39 ~\Anaconda3\envs\py3\lib\site-packages\pandas\core\series.py in wrapper(self) 139 if len(self) == 1: 140 return converter(self.iloc[0]) --> 141 raise TypeError(f"cannot convert the series to {converter}") 142 143 wrapper.__name__ = f"__{converter.__name__}__" TypeError: cannot convert the series to <class 'int'>

| Partial itertools.product in python Posted: 16 Dec 2021 03:39 AM PST I would like to create the following list of tuples in Python, based on a list of possible values [0, 1, 2, 3]: (0, 0, 0), # all set to first value: 0 (0, 0, 1), (0, 0, 2), (0, 0, 3), (0, 1, 0), (0, 2, 0), (0, 3, 0), (1, 0, 0), (2, 0, 0), (3, 0, 0), (3, 3, 3), # all set to last value: 3
To summarize: - first value (
0) for all elements of the tuples - each value of the list of values (
[0, 1, 2, 3]) for a given element of the tuple and other elements set to 0 - last value (
3) for all elements of the tuples What would be an efficient way to do it? ... maybe there is a magic function to do it? I was first thinking of using itertools.product and then filtering: list(product([0, 1, 2, 3], repeat=3))
... or maybe by using pandas (which looks a bit overkill though). Thanks |

| Standard Deviation Per Group With Condition Posted: 16 Dec 2021 03:39 AM PST I have a dataset that looks as follows: id year value 1 2000 1 1 2002 3 2 1999 10 2 2000 8 2 2001 9 3 2000 12 3 2001 5 3 2003 6 3 2004 7 3 2005 13 3 2006 2 3 2007 1 4 2005 5 4 2006 5 4 2007 5 4 2008 4 4 2009 7
I now want to add a column that indicates the recursively calculated standard deviation per ID, including at least 5 prior years of data (including the respective current year; the fact that years might be missing is ignored), i.e.: id year value SD 1 2000 1 NA 1 2002 3 NA 2 1999 10 NA 2 2000 8 NA 2 2001 9 NA 3 2000 12 NA 3 2001 5 NA 3 2003 6 NA 3 2004 7 NA 3 2005 13 3.26 3 2006 2 3.86 3 2007 1 4.24 4 2005 5 NA 4 2006 5 NA 4 2007 5 NA 4 2008 4 NA 4 2009 7 0.98
The solution to this can rely on the fact that the data is ordered by id and year. However I also appreciate solutions that do not explicity rely on ordering. Any help is appreciated, thanks. |

| Nodejs module.parent condition not working on ubuntu server Posted: 16 Dec 2021 03:39 AM PST I am working on an existing project and found this piece of code in my app.js //if (!module.parent) { // Server listen app.listen(mysettings.port, function () { console.log(`Server ready at ${ENV}:${mysettings.port}`); }); //}
When I run locally, app.listen hits and my project runs, when I upload my project on a ubuntu server, the project does not run, but times out. When I comment out the condition on ubuntu the project runs perfectly. I know on my localhost, module.parent is null. Any help would be apperciated. |
| Yarn packages out of date when running Rails app in Docker Posted: 16 Dec 2021 03:38 AM PST I start my Rails 6 app as Docker containers, but when it starts the Rails server, it keeps giving the error: warning Integrity check: System parameters don't match website_1 | error Integrity check failed website_1 | error Found 1 errors. website_1 | website_1 | website_1 | ======================================== website_1 | Your Yarn packages are out of date! website_1 | Please run `yarn install --check-files` to update. website_1 | ======================================== website_1 | website_1 | website_1 | To disable this check, please change `check_yarn_integrity` website_1 | to `false` in your webpacker config file (config/webpacker.yml).
So why is this not working? I have that command in the Dockerfile and also that check is disabled in webpacker.yml. I build it with docker-compose up --build and then it doesn't seem to give errors. When I start it with docker-compose up, it will return the erorr when the Rails server is started. Here are the relevant files: Dockerfile: FROM ruby:2.6.5-slim LABEL maintainer="John van Arkelen <johnvanarkelen@fastmail.com>" RUN apt-get update -qq && apt-get install -y curl build-essential libpq-dev postgresql postgresql-contrib RUN mkdir /app RUN mkdir -p /usr/local/nvm WORKDIR /app RUN curl -sL https://deb.nodesource.com/setup_11.x | bash - RUN apt-get install -y nodejs RUN node -v RUN npm -v ENV BUNDLE_PATH /gems RUN gem install bundler -v 2.0.2 COPY Gemfile Gemfile.lock package.json yarn.lock ./ RUN bundle install RUN npm install -g yarn COPY . /app RUN yarn install --check-files

| Heap Analytics for react native app Posted: 16 Dec 2021 03:38 AM PST Heap Analytics automatically tracks all events so you can analyze data in hindsight without having to manually define all events upfront. Unfortunately, Heap does not seem to work in this way when used with a react native app. Does anybody know an analytics solution for React Native iOS, where all events are tracked automatically or how to get Heap working in that way without having to define all events manually? Thanks in advance. |
