Random "Freezing" with AMD Ryzen CPUs

It seems that numerous GNU/Linux users (including myself) have been having issues with the system randomly "freezing" during light usage. From journalctl output and anecdotal accounts, it is speculated that the AMD Ryzen CPUs do not support other C-states for power management very well (at least on GNU/Linux distributions), and the freezing may be resolved by limiting the C-state of the CPU.

Possible Solution

Limiting the C-state of the CPU can be done through the addition of the following kernel boot parameter.

processor.max_cstate=1

Downgrade Virtualbox guest additions in your virtual machine (Ubuntu 16.04)

Make sure your VM is running and ssh into it. From there, run the contents of downgrade-vbox-guest-additions.sh below.

Stop vagrant-vbguest automatic updates

From your host machine, if you have the vagrant-vbguest plugin installed, make sure you deactivate it for this specific VM. To do that, set auto_update to false in your Vagrantfile:

config.vbguest.auto_update = false

Formats

Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in that tuto.

Note that the reST is recommended by the PEP 287

There follows the main used formats for docstrings.

I am deploying with this IAM using Codeship and Circle CI to Elastic Beanstalk. I had a lot of trouble with this config. I talked to the aws support for about 6 hours until this worked properly, so, I guess it is worth to share.

UPDATE: In the end, I have to use the AWSElasticBeanstalkFullAccess policy. My custom policy keep breaking every week with some new added permission or some EB internal change. Anyway, the IAM I was using is below.

This works for me with CircleCI and EB Cli.

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

	import io
	import sys


	class RedactIO(io.IOBase):
	"""
	A minimal io wrapper to redact sensitive data.
	"""

	def __init__(self, buffer, redactions: dict[str, str], **kwargs) -> None:

 def docx_replace(doc, data):
 	paragraphs = list(doc.paragraphs)
 	for t in doc.tables:
 		for row in t.rows:
 			for cell in row.cells:
 				for paragraph in cell.paragraphs:
 					paragraphs.append(paragraph)
 	for p in paragraphs:
 		for key, val in data.items():
 			key_name = '${{{}}}'.format(key) # use placeholders in the form ${PlaceholderName}
