gsub error message when addressing column in dataframe in RStudio

gsub error message when addressing column in dataframe in RStudio

Since a couple of days I get the following error message in RStudio from time to time and cant figure out what is causing it. When I write in the console window to address a data.frame followed by to address a specific column in the data.frame for example dfSomeVariable, the following message is shown in the console window and is printed over an over with every letter I type Error in gsubreStrip, , completions, perl TRUE : input string 38 is invalid UTF-8 The error message doesnt have any real effect. Everything works just fine except the automatic completion of the variable name. Im using R version 3.4.4 and RStudio Version 1.0.143 on a Windows computer. In the R script I am currently working on I dont use gsub or any other string or regular expression function for that matter. The issue appeared with various data.frames and various types of variables in the data.frames numeric, integer, date, factor, etc.. It also happens with various packages. Currently, I am using combinations of the packages readr, dplyr, plm, lfe, readstata13, infuser, and RPostgres. The issue disappears for a while after closing RStudio and opening it again but re-appears after working for a while. Does anyone have an idea what may cause this and how to fix it

Connection string for MariaDB using ODBC

Connection string for MariaDB using ODBC What is the connection string for using MariaDB with ODBC Im guessing its something like DRIVERMariaDB ODBC 5.1 Driver; SERVERLOCALHOST; PORT3306; DATABASEDatabaseName; UIDroot; PASSWORDpassword;OPTION3; Connection strings seems to show strings for MySQL but not MariaDB. MariaDB seems to have a lot of connection strings for Access, SQL Lite, excel, etc ... What have I missed Although this is late answer, but MariaDB have that documented here SQLWCHAR ConnStr LDriverMariaDB ODBC 2.0 Driver;Serverlocalhost;UIDodbc_user;PWDodbc_pw;DBodbc_test;Port3306;

Celery like system based on django channels

Celery like system based on django channels According to the docs of django channels: http:channels.readthedocs.ioenlatestconcepts.htmlhighlightcelerynext-steps One thing channels do not do, however, is guarantee delivery. If you need certainty that tasks will complete, use a system designed for this with retries and persistence e.g. Celery, or alternatively make a management command that checks for completion and re-submits a message to the channel if nothing is completed rolling your own retry logic, essentially. I worked with celery some years ago. Yes, it is great, it is big, it is too much. I would like to avoid it. I am searching a simple tasks queue with guarantee delivery and a re-submission on failure. An other alternative would be python-rq. But this has other disadvantages like using pickle data format instead of json. A friend gave me an advice: https:github.comfurious-lukedjango-cq Looks good. From the docs An attempt to implement a distributed task queue ...
