kandi X-RAY | lumberjack Summary
Production scripts may contain many data transformations, aimed to clean, select, model, or augment data with new variables. Analyzing the effect of each step is cumbersome because it involves adding a lot of code that is not concerned with the primary goal of the script, namely to analyze and process data. In the lumberjack philosophy, a programmer (analyst) should be only concerned with the primary process of data analyses.

QUESTION
How do I use AWS Cloudwatch Log Insights' replace function?
The docs do not give working examples.
Given logs which contain paths such as /api/lumberjack/123/axe/456/fashion
I am trying:
...ANSWER
Answered 2022-Jan-10 at 14:59The error message is pretty self-explanatory. The replace function expects an input of type string for the first argument. You provided a fieldname path which is not acceptable.
EDIT: To my surprise, the replace function accepts path as the first argument, which is not mentioned in the doc. See Omar's answer above.
QUESTION
I tried to cluster my dataset using K-mean, but there is a categorical data in column 9; so when I ran k-mean it had an error like this:
...ANSWER
Answered 2021-Dec-17 at 17:31To solve your specific issue, you can generate dummy variables to run your desired clustering.
One way to do it is using the dummy_columns() function from the fastDummies package.
QUESTION
I ran multiple imputation to impute missing data for 2 variables of a data frame, then I got a new data frame (with 2 columns for 2 imputed variables).
Now, I want to replace the 2 columns in the original data frame with the two newly imputed columns from my new dataframe. What should I do?
Original data frame new data frame for imputed variables
This is the code I used. Only 2 columns in this data frame are missing data, so I only imputed those two. Is that ok? Can you please suggest me a better way?
...ANSWER
Answered 2021-Dec-14 at 22:53Updated
As @dcarlson recommended, you can run mice on the entire dataframe, then you can use complete to get the whole output dataframe. Then, you can join the new data with your original dataframe.
QUESTION
I use logrus and lumberjack for log file on macOS.
...ANSWER
Answered 2021-Nov-01 at 11:20Based on the stated behaviour, I assume this is happening on an OS which implements POSIX-compatible behaviour for files (so it's running on some kernel with Unix heritage — such as *BSD or Linux, — or it's a Mac OS system).
On these systems, removing a file from a file system does nothing to that file's storage on that file system — as long as it is opened in at least a single running process.
Specifically, to cite the POSIX documentation on open(2):
If the link count of the file is 0, when all file descriptors associated with the file are closed, the space occupied by the file shall be freed and the file shall no longer be accessible.
Having a file open is considered to increment its link count by 1, and removing a file from its filesystem is the same as decrementing that link count by 1.
You might read more about link counts here.
Supposedly the logging package you're using keep the log file opened, and so what happens is that you merely remove the file's name from the filesystem's directory it was it, but this does not in any way affect the logging process.
Moreover, the process which has the file open is not notified when any of the file names goes away (on Unix-like systems a file might have many names at the same time—read about hard links).
Typically for Unix-like OSes is to have a way to explicitly ask the process to re-open its log file(s).
Casually, a SIGUSR1 signal is used for this, so you could setup a handler (via signal.Notify) to setup a handler for such a signal and then make your log rotation code to kill -USR1 the running process to tell it re-open the log file, which will be recreated.
Of course, more involved schemes could be implemented as you can use any form of IPC to communicate that command to your running process.

As per the title, I am trying to clean a large compilation of short texts, to remove sentences that start with certain words -- but only if it is the last of >1 sentences that text.
Suppose I want to cut out the last sentence if it begins with 'Jack is ...'
Here is an example with varied cases:

QUESTION
I have two tables. First one stores user information called "users"
...ANSWER
Answered 2021-Jun-20 at 13:17Concerning your query add WHERE clause to it.
Eg if the user id is 26 SQL query will be
SELECT lumberjack, stonemanson, farmer FROM materials JOIN users ON materials.user = users.user WHERE users.user=26
And checking your table structure, if you will not need any data from the users table then you shouldn't bother to use JOIN
this will also work fine and it'll be faster
SELECT lumberjack, stonemanson, farmer FROM materials WHERE materials.user =26
NB: using query() makes your code vulnerable to SQL injection You should use Mysqli or PDO prepared statement.
Stackoverflow has many answers on that. So after you have resolved your issue, then start read on SQL injection and use of PDO or Mysqli prepared statement
QUESTION
Every time I publish a Kotlin Multiplatform Mobile library to maven central the only I can seem to add/use the Android dependency in an Android app is by adding both the releaseImplementation and debugImplementation
Example
...ANSWER
Answered 2021-May-28 at 01:36You should not specify -android postfix, just use implementation("io.github.tyczj.lumberjack:Lumberjack:1.0.0").
This works because dependency variant resolution is based on Gradle Module Metadata. This metadata is just another file published with your library (it has .module extension) and it contains description of all variants. As you are publishing the library as a whole, the top-level artifact io.github.tyczj.lumberjack:Lumberjack contains the metadata for the whole library, allowing gradle to choose the right variant.
Another option would be to make sure your -android artifact contains proper module metadata with both release and debug variants. I believe publishLibraryVariantsGroupedByFlavor is the way to tell the publisher plugin to make it this way, but I have not tried it.
QUESTION
Here's was appears to be an odd question at least from what I've been able to turn up in Google. I'm not trying to determine IF there's a UAC prompt (I've got a couple of reliably ways to do that, win32gui,GetForegroundWindow() returns a 0, or win32gui.screenshot returns exception OSError at least in my case)
I'm also not looking to BYPASS the UAC, at least from python, I have an update process that's kicking off automatically that I need to get through the UAC. I don't have control of the update process so I don't think it's a good candidate for disabling the UAC with Python. I could just disable the UAC in Win10, but I'd prefer not to if possible. I do have a couple of methods for bypassing the UAC, in one instance where I'm running this in vitualbox I believe I can use VBoxManage guestcontrol to sent keystrokes to the guest system, for a stand alone system I have a microcontroller connected as a USB HID Keyboard, with a basic deadman switch (using the scroll lock to pass data between the python and the microcontroller acting as the HID keyboard) if it doesn't get the signal it sends left arrow enter to bypass the UAC.
What I'm trying to do, and getting stymied with, is verifying that the UAC popup is actually from the update process that I want to accept the UAC prompt for, and not some other random, possibly nefarious application trying to elevate privileges. I can use the tasklist to verify the UAC is up, but I'm not seeing any way to see WHAT caused the UAC prompt. The update process is kicked off from an application that's always running, so I can't check to see if the process itself it running, because it's running under normal operation, I just want to accept the UAC when it's attempting to elevate privileges to update. I've been using a combination of using win32gui.GetWindowText and win32gui.EnumWindows to look for specific window titles, and for differentiating between windows with the same title, taking a screenshot and using OpenCV to match different object that appear in the windows. Both of those methods fail though when UAC is up, which is why I can use them to detect UAC as I mentioned before.
I suppose I could use a USB camera to take a screenshot of the system, but I'd like to be able to run this headless.
Anybody have an idea on a way to accomplish this, as the tree said to the lumberjack, I'm stumped.
...ANSWER
Answered 2021-May-12 at 18:58If you run a process as administrator, no user account control prompt will appear. You could manually run your process as administrator. You need system privileges to interact with a user account control prompt.

QUESTION
Using the w3schools.com SQL tutorial Northwind database, I'm trying to display the category that has the most products shipped. Additionally, I want to display the net income from all sales in that category. I can't figure out how to take the category with the most products shipped, and use the amount of products shipped to calculate the net income of that category. This is because there are many different products that have the same CategoryID but different prices.
...ANSWER
Answered 2021-Jan-25 at 07:24So first of all you get the income for each product and category and then based on that you find total income for that category and you do this with the help of subquery, then you join this resultant table with the category table and with the help of group by you find the product count and total income for each category, below is the sql query for more indepth understanding
