Getting calculation using three tables in MySQL

Asked 2022-Apr-16 at 11:28

I am trying to calculate the total cost of each task. There is a task assignment table which has the task assigned to a specific employee with start to finish date & time. On the other hand, there is another table which holds the hour wages rate for an employee. For a task, the cost will be the number of hours they work multiply by their wagers rate. Plus I have another table which also have various cost/expenses that has to be added to the sum to get the final cost for a task.

So my approach was that I converted start & finish time to seconds using TO_SECONDS then substracted finish from the start to calculate total hours an employee worked. Then I tried to extract the wagers rate for an employee and then multiply it. However, my output is not accurate, and sometimes not even close.

My appraoch seems to be logical. However my query or understanding is not right. Firstly I am presenting my table structure.

Task Table: Within this table I store various task details such titile, location, commence date etc.

Task Assignment: This table holds the information regarding which task is assigned to which employee with start and finish time for the employee to work on.

Employee wagers related table: This table tells the hourly wages rate for each employee.

Additional Cost: In this table I have cost that they each belongs to a task in the task table using the joining key task_id.

Now I am going to show you my query that I wrote.

You need to do the multiplication by the wage rate within the sum. You're calculating the sum of hours, and then multiplying that by just one of the rates in the group. So if the task was done by multiple people, you're picking one of them and using their wage as the rate for the entire task.

Error whilst running a state space equation using python GEKKO library

Asked 2022-Mar-23 at 01:05

Attempting to model thermal losses from a building, I have implemented the following code to run the model using a state-space equation. It seems to take in variables as expected from .csv files and arrange them into correctly formed matrices. However, it is returning "Exception: Data arrays must have the same length, and match time discretization in dynamic problems". When trying to debug I printed all the matrices in the equations to see if they matched (see below). I feel like this should be easy to see but I don't know where I have gone wrong.

Answered 2022-Mar-23 at 01:05

The code needed some modifications to import the data but the model was good. The script was also missing the data file and the btype variable. Here is some sample data for testing with data.csv.

"mount: /dev/mqueue: must be superuser to use mount" when starting a Yocto Linux system via NFS and TFTP

Asked 2022-Mar-12 at 09:16

I followed the guide "Yocto NFS & TFTP boot" from the i.MX knowledge base to make my embedded Linux device run a kernel and a filesystem on my development machine.

The kernel seems to be correctly loaded via TFTP, but the system doesn't boot up properly and systemd goes into maintenance mode.

Here's the first error in the log:

Answered 2022-Mar-12 at 09:16

The message must be superuser to use mount is a hint to a permission problem.

The Linux system expects most system files to be owned by UID 0 (root), but when reading the NFS filesystem set up in the guide it actually reads UID 1000, or the UID of whoever built the system in the development machine. If I list the contents of ${YOCTO_BUILD_DIR}/tmp/work/${TARGET}-poky-linux-gnueabi/${IMAGE}/1.0-r0/rootfs, I get:

QUESTION

Databricks Feature Store - Can I use native Python (instead of PySpark) to create features?

Asked 2022-Mar-12 at 08:59

I would like to create a feature table with some popular time series features using out of the box feature transformations provided by popular python packages such as ta-lib or pandas-ta - these packages rely on numpy/pandas and not Spark dataframes.

Can this be done with Databricks Feature Store?

In the documentation I could only find feature creation examples using Spark dataframes.

...

ANSWER

Answered 2022-Mar-12 at 08:59

When it comes to creation - yes, you can do it using Pandas. You just need to convert Pandas DataFrame into Spark DataFrame before creating the feature store or writing new data into it. The simplest way to do it is to use spark.createDataFrame function, passing Pandas DataFrame to it as an argument.

ANSWER

Answered 2022-Feb-22 at 09:06

The general answer to your question is that Plots uses the bang (!) naming convention to naming functions which mutate an existing plot object. Therefore if you want to add something to another plot, you should call plot! (or scatter!, bar!, etc.) after your first plot call.

In your case, the high level solution would therefore be:

You can only have 1 indicator() or study() tag in a script.
