journal | : notebook : A simple self-hosted journaling app | Privacy library

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:

I am trying to scrape specific portions of html based journal articles. For example if I only wanted to scrape the "Statistical analyses" sections of article in a Frontiers publication how could I do that? Since the number of paragraphs and locations of the section change for each article, the selectorGadget isn't helping.

I've tried using rvest with html_nodes and xpath, but I'm not having any luck. The best I can do is begin scraping at the section I want, but can't get it to stop after. Any suggestions?

I am trying to understand how ActiveMQ Artemis manages the journal files (under data/journal) and when it creates new ones. I read the documentation, but it wasn't clear how the files are create. I have a broker.xml has simple settings (won't be able to share unfortunately). Here are a few:

• journal min threads - 2
• journal pool size - 50
• file size is defaulted to 10MB.

ActiveMQ Artemis starts, and I see 2 files are already created under /data/journal. I am now running a request that posts a lot of messages in a very short time. These messages are being actively consumed. I am publishing a lot of messages but they are not accumulating as fast because the consumer is consuming them. However, this doesn't cause the files to grow to recreate the space issue.

As the message volume is going up I don't see the number of files going up. It goes up and stays at 12 files for a long time. I can understand the message # is not sufficient trigger additional files if only the latest journal file is being written to. However, I see all the 11 files have updated timestamps making me think they are being rotated.

My paging directory is empty.

I am trying to understand why the journal is not growing despite the message volume.

In case we had the model:

I want to find the simplest barebones (that is, no libraries if possible; this is a learning exercise) way to draw a simple line between components. The elements are divs representing cards always stacked vertically potentially forever. Cards can be different heights. The line will exit the left hand side of any given element (card a), turn 90 degrees and go up, turning 90 degrees back into another (card b).

I've tried a few things. I haven't got any fully working yet and they're looking like they all need some serious time dedicated to figuring them out. What I want to know is what's the right/preferred way to do this so that I spend time on the right thing and it's future proof with the view:

1. I can add as many connecting lines as I need between any two boxes, not just consecutive ones
2. These lines obey resizing and scrolling down and up the cards
3. Some cards may not have an end point and will instead terminate top left of page, waiting for their card to scroll into view or be created.

My first thought was a in a full column component on the left but aligning canvas' and the drawings in them to my divs was a pain, as well as having an infinite scrolling canvas. Couldn't make it work.

Next I tried

Lastly I tried s. Just .getElementById() then add an SVG path that follows the instructions above. i.e.

I have two dataframes - the list of influential medical journals and the list of articles from a broader list journals.

I work in a library, and we get a regular database output in a csv that has journal article information (title, author, abstract, etc.). It has 67 columns, and the column names are the same every time. Each row has citation information for a different journal article. The goal is to create a spreadsheet of full citations in one column (by pasting together different columns like author and publication date) and open-access status in another column, with the extraneous columns deleted. I wrote some R code that automatically gets rid of the unnecessary columns and pastes the rest together, which worked fine when I was the only one cleaning. However, my supervisor wants others in the office to be able to perform the work and asked that I make an R Shiny app to do so. I've never created one before. While I've managed to write the code for the uploading and downloading portions of the script, I'm having trouble actually getting the cleaning portion to work. This first bit of code is the cleaning that I already have working, outside the app, which works.

I am learning Linux programing.
When I trying to write a simple module to get family of a process, I find I can not get current pid of a process and its parent process. How to fix it?
Here is a part of my code.

Liferay 7.4 stores the structure data in the "ddmfieldattribute" table. I'm trying to get the fields of the structures in the ADT template, but I can't find the solution.

The structure has the following fields:

• title
• content

The ADT code is as follows:
