I have a json object (json string) which has values like this:

I'm trying to make a chart (either with lines or bars) to show periods of time in certain Stages. Using the data below, the closest I've gotten is to try to get a Gantt chart and turn off the color for the start date, only showing the duration. Rather than the duration in days on the x-axis, I'd like it just to be dates (months or years).

(screenshot - Gantt chart example - note the multiple appearances of "Cultivate")

It's close to what I want, but the stage can be reentered multiple times. So I would like those separate Cultivate periods/bars on one line. Something like this:

Data:

I have some code that I could cross-compile with an older toolchain that used uClibc, but the project is moving to musl libc, and I can't seem to get the code to compile with that toolchain. It always fails during the linking stage with a bunch of errors along these lines:

I am new to regular expressions and I have a text as follows. How can I use the RegEx to extract all words with at least one digit in it? Really appreciate it.

I'm replacing an older cross-compile toolchain, and I can't figure out how to get buildroot to include host/.../sysroot/usr/include/boost like the old toolchain had.

Context:

I'm trying to build a docker image that can be used to cross-compile software for MiyooCFW in GitHub Actions. Here is my current Dockerfile.

The project moved from uClibc to musl libc, which is why the toolchain needs to be updated.

The older toolchain that actually works is a .zip file on google drive. I think it was probably built using Makefile.legacy in this buildroot fork. The newer one uses make sdk with the main Makefile there. (There is a bit of documentation, but it's incomplete.)

I installed libboost-all-dev which puts the libraries in /usr/include/boost/ but just having them installed is apparently not enough.

GMenuNX is an example program I'm trying to cross-compile that depends on boost. The steward branch uses a docker image with the older toolchain and compiles successfully. The ci branch uses my new docker image and fails with:

According to (steward,1998). A matrix A which is invertible can be approximated by the formula A^{-1} = \sum^{inf}_{n=0} (I- A)^{n}

I tried implementing an algorithm to approximate a simple matrix's inverse, the loss function showed funny results. please look at the code below. more info about the Neumann series can be found here and here

here is my code.

I've done some searching on the internet but haven't be able to find an answer or solution. I'm wondering whether it is possible to apply logic within PhpMyAdmin to prevent certain users appearing in the aliases list on another table?

I have a "users" table and a "races" table. In the races table I have a column called "Steward" which is a foreign key (index) referencing the primary key of the user table. The problem is not all the users in the users table have the privilege of being a steward. Is there a way to stop the non-steward users appearing in the races table?

For further support, here's my users table:

Here's my races table:

In summary, I don't want the users who don't have the access level of "steward" in the users table appearing in the races "stewards" column of the races table.

I'm using R to work with the US county-level voting data that the good folks at MIT steward. I'd like to know the total votes each candidate got in each county. For some states, such as Wisconsin, that's easy:

Attempted Solution at bottom of post.

I have near-working code that extracts the sentence containing a phrase, across multiple lines.

However, some pages have columns. So respective outputs are incorrect; where separate texts are wrongly merged together as a bad sentence.

This problem has been addressed in the following posts:

• Solution 1
• Solution 2

Question:

How do I "if-condition" whether there are columns?

• Pages may not have columns,
• Pages may have more than 2 columns.
• Pages may also have headers and footers (that can be left out).
