| Vaex expression to select all rows Posted: 29 Apr 2022 12:26 PM PDT In Vaex, what expression can be used as a filter to select all rows? I wish to create a filter as a variable and pass that to a function. My wish is that if x <= 5 it will ignore the filter (thus I'm trying to use True as a value). Doing it this way gives the error | ||||||||||||||||||||||||||||||||||||||||||||||||

| How to route two machines in different local networks? Posted: 29 Apr 2022 12:25 PM PDT I cannot connect from my Ubuntu server (10.10.57.5) back to my personal PC (10.15.0.4) which is on a different local network. The server has the following ifconfig: I connect to it through 10.10.57.5, and 10.10.20.0/24 is another network that cannot be reached externally. This is the route info: If I try to ping my local machine from the server, it obviously does not return anything as it's outside the network: Then, I tried to configure the network like this: And suddenly, the ping command suddenly works: However, I cannot see anything in my tcpdump in my local machine: Finally, if I host a server on my local machine: It cannot be reached from the server: If also tried to add a new route without success: What am I missing? | ||||||||||||||||||||||||||||||||||||||||||||||||
| In Python, If there is a duplicate, use the date column to choose the what duplicate to use Posted: 29 Apr 2022 12:25 PM PDT I have code that runs 16 test cases against a CSV, checking for anomalies from poor data entry. A new column, 'Test case failed,' is created. A number corresponding to which test it failed is added to this column when a row fails a test. These failed rows are separated from the passed rows; then, they are sent back to be corrected before they are uploaded into a database. There are duplicates in my data, and I would like to add code to check for duplicates, then decide what field to use based on the date, selecting the most updated fields. Here is my data with two duplicate IDs, with the first row having the most recent Address while the second row has the most recent name.
Here is a snippet of my code showing the 5th testcase, which checks for the following: Record has Name information, Spouse has name information, no one is marked deceased, but Addressee or salutation doesn't have "&" or "AND." Addressee or salutation needs to be corrected; this record is married. What is the best approach to check for duplicates, choose the most updated fields, drop the outdated fields/row, and perform my test? | ||||||||||||||||||||||||||||||||||||||||||||||||

| C: How to properly reallocate an array of strings Posted: 29 Apr 2022 12:26 PM PDT This seems like a simple question and probably a simple answer but I am trying to read in words from a text file and allocate each word to a dynamically allocated array of strings: (It must be allocated this way.) And then I must resize the array as needed. My problem comes when I try to use Where MAX is the max number of elements that can be stored in the array. My array is populated with correct values but when realloc is called some strings appear to be missing! Several indexes are not populated anymore and I get a memory error when trying to print the array out as they are missing somehow. Here is how I allocate the strings and store them at the index: What's going wrong? | ||||||||||||||||||||||||||||||||||||||||||||||||

| Accessing Walmart API and setting up product mapping Posted: 29 Apr 2022 12:26 PM PDT To start: I'm completely new to working with APIs, so please bear with me. My first question is related to getting access to the Walmart API. I see the example code to generate time stamp and signature. How do I run this file? I've looked at YouTube videos, the Walmart tutorial, and other posts in this forum and am still a little stuck. Second, I'm guessing this file needs to be included in the actual application to continue to be able to access the products? Third, my goal is to map only a subset of the product catalog for users of the app to view. Let's use 'soda' as an example. Is it the Taxonomy API I need to use? And how do I limit the available products a user can search? Note: This will be implemented in a Flutter application, if it makes any difference. | ||||||||||||||||||||||||||||||||||||||||||||||||
