58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

<statechart> = (state / <whitespace> / <comments>)+

state = comments? state-name <whitespace>? <newline> block?
transition = comments? event-name <whitespace>? <'->'> <whitespace>? state-name <newline>

<block> = indent (state / transition / <whitespace> / <comments>)+ dedent

comments = comment (<newline> comment)* <newline>
<comment> = <'#'> #".*"

# Load the contents of the receipt file
receipt_file = open('./receipt_data.bin', 'rb').read()

# Use asn1crypto's cms definitions to parse the PKCS#7 format
from asn1crypto.cms import ContentInfo
pkcs_container = ContentInfo.load(receipt_file)

# Extract the certificates, signature, and receipt_data
certificates = pkcs_container['content']['certificates']
signer_info = pkcs_container['content']['signer_infos'][0]

This is a working example on how to store CryptoKeys locally in your browser. We are able to save the objects, without serializing them. This means we can keep them not exportable (which might be more secure?? not sure what attack vectors this prevents).

To try out this example, first make sure you are in a browser that has support for async...await and indexedDB (latest chrome canary with chrome://flags "Enable Experimental Javascript" works). Load some page and copy and paste this code into the console. Then call encryptDataSaveKey(). This will create a private/public key pair and encrypted some random data with the private key. Then save both of them. Now reload the page, copy in the code, and run loadKeyDecryptData(). It will load the keys and encrypted data and decrypt it. You should see the same data logged both times.

Quick List of Resources for Topological Data Analysis with Emphasis on Machine Learning

This is just a quick list of resourses on TDA that I put together for @rickasaurus after he was asking for links to papers, books, etc on Twitter and is by no means an exhaustive list.

Survey Papers

Both Carlsson's and Ghrist's survey papers offer a very good introduction to the subject

• Topology and Data by Gunnar Carlsson
• Barcodes: The Persistent Topology of Data by Robert Ghrist

Other Papers and Web Resources

• Extracting insights from the shape of complex data using topology A good introductory paper in Nature on the Mapper algorithm.

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:
